Description

  The present invention provides a resin melt injection apparatus for injecting a large number of plastic pellets and injecting the molten resin in a heated melter and an adapter, and the first member and the second member are connected to each other by the resin. The present invention relates to a first member and a second member that are resin-bonded by a resin-bonding device that can improve the speediness and airtightness of the molten resin from the melt-injection device.

  Generally, there are screw type and plunger type injection devices. As a typical example, as disclosed in Patent Document 1 for a screw type, and as disclosed in Patent Document 2 for a plunger type, each is mainly composed of a cylinder and a screw. The pellets introduced from the hopper provided in the cylinder are transferred to the injection nozzle side by the rotation of the screw inside the cylinder, and are heated and melted in the transfer process. Then, the molten resin is collected at the tip of the nozzle, injected, and the molten resin is sent to the mold.

  General plastic pellets (hereinafter simply referred to as “pellets”) are made of plastic (synthetic resin) and have a thermal conductivity of about 0.07 to 0.20 kcal / m · hr · ° C. This is one-hundredth to several-thousandth of the thermal conductivity of the metal, and thus, the pellet can be said to be a substantially heat insulating material. Therefore, even when sufficient heat of fusion is applied to melt the pellet, it is difficult for the heat to be transferred to the inside (center) of the pellet, and it takes a considerable time to be sufficiently heated.

  Accordingly, it has been impossible in a short time until the individual pellets are sufficiently melted and ready for resin molding. For this reason, the pellets have to be melted for a relatively long time in the cylinder, and the working efficiency is not good. Further, in the injection device, each of the solids of a large number of pellets charged into the cylinder is heated and moved to the injection side when the screw rotates, and at this time, a part of the large number of pellets is moved to the inner wall of the cylinder. It will be in a state of being pressed against.

  That is, it is pressed against the cylinder inner wall. And also about each pellet pressed, only a part of the surface of the solid contacts a cylinder inner wall, and melting of each pellet only melts the pellet solid partially. Pellets that are kneaded by the screw in the cylinder are separated from the inner wall of the cylinder in a short time, are not heated sufficiently, the pellet solid is not melted as a whole, and most of the pellets are mixed with the molten part and the unmelted part It becomes a state.

  By repeatedly pressing the pellet against the inner wall of the cylinder with the screw, the pellet is completely melted, and even when the melted pellet is transferred to the vicinity of the nozzle, the amount of resin stored in the cylinder is one time. This amount is more than several tens of times the amount required for the injection, and a wasteful amount of pellets remains in the cylinder.

  Further, when the molten resin passes through the gap between the screw and the cylinder, the resin is mechanically damaged. In particular, when melting glass fiber-containing pellets, there are many problems, and the screw is worn. Also, since each pellet is randomly melted only partially, it is inevitable that the same pellet will remain in the cylinder indefinitely. Therefore, the work is particularly difficult when changing the material in the pellets in the cylinder.

  There is a plunger type for such a screw type. This type has a simple structure and is easy to downsize. Also, the plunger type does not have the disadvantage that the screw is worn. Patent Document 2 is of the plunger type having the most basic structure, and is mainly composed of a frustoconical heating cylinder having a large number of through holes, an injection plunger, a supply cylinder, and the like. . The synthetic resin raw material is sent out to the heating cylinder by the injection plunger, and injection is performed. However, Patent Document 2 also has various problems.

  In Patent Document 2, the injection plunger and the frustoconical heating cylinder have different diameters, and the diameter of the injection plunger is slightly smaller than the diameter of the facing portion of the heating cylinder. . In addition, a gap chamber having a volume larger than the area of the tip of the injection plunger exists between the tip of the injection plunger, the heating cylinder, the tip of the injection plunger, and the supply cylinder.

  Therefore, the molten synthetic resin raw material is once extruded into the gap chamber by the injection plunger, but even if the injection plunger further moves to the heating cylinder side, the synthetic resin raw material efficiently flows into the through hole of the heating cylinder. There is a possibility that it will not flow into the heating cylinder and remain in the gap chamber. And the synthetic resin raw material remaining in the space may be a hindrance to the synthetic resin raw material to be newly sent out to the through hole of the heating cylinder. Moreover, there is a sufficient possibility that the synthetic resin raw material to be newly sent out and the resin that has deteriorated due to remaining for a long time are mixed.

  The present applicant has improved an inconvenient point of such a frustoconical heating cylinder and an injection plunger, and an injection device in a molding machine capable of efficiently performing a pellet resin melting process and a molten resin injection process. Was developed in Patent Document 3. In this patent document 3, the pellets can be melted by the resin only by pressing the aggregate of the pellets with the plunger, and the pellets can be melted by the resin. It is possible to provide an epoch-making invention that can be performed.

  In the present invention, as a melting step for melting the pellets, the molten resin passes through a large number of conical holes of the heated melter at a predetermined pressure, and becomes a molten resin when it exits from the pellet solid. That is, the melting speed and the injection speed are the same in relation to the material of the pellet, the viscosity of the molten resin, the melting temperature, the pressure, the melting speed, the extrusion speed, the flow rate, and the like. Then, when considering the melting rate, it can be melted fairly quickly. Furthermore, it has succeeded in making it much smaller and lighter than conventional injection devices, and further uses have been devised.

  Cited Document 3 discloses an invention in which an appropriate member is connected by an injection device. In this apparatus, a conventional injection apparatus is used, and in fact, there is a serious drawback that the gate portion is complicated and the hole diameter is small and a smooth connection cannot be made. In particular, it has been desired to use a small resin melt injection apparatus to join at least two members while improving airtightness, not rivets, bolts / nuts, welding, or the like.

  The invention according to claim 5 is characterized in that an outlet member is provided on the front end injection side in the longitudinal direction, a closing portion is provided on the rear side, and a pellet supply port for supplying plastic pellets to an intermediate position between the closing portion and the outlet member is provided.

The above-mentioned problem has been solved by using the first and second members joined by the resin, wherein the coupled holes are formed as screw holes.

  According to a sixth aspect of the present invention, in the first, second, second, or third aspects of the present invention, the resin-bonded device according to any one of the first, second, third, fourth, and fifth aspects is manufactured by a robot arm. By using the member and the second member, the above problems have been solved. According to a seventh aspect of the present invention, in any one of the first, second, third, fourth, fifth, and sixth aspects, a heat insulating material is interposed between the nozzle portion of the outlet member and the first adapter. In the resin bonding apparatus, the molten resin is injected between the coupling holes drilled in the first member and the second member, respectively, and the one side outer surface of the first member and the second member is melted on the one side The above-mentioned problems are solved by using the resin-bonded first member and the second member, which are manufactured by resin bonding so that the resin does not bulge.

According to the first aspect of the present invention, the first member and the second member are connected to each other by the resin melting injection apparatus and the adapter for injecting the molten resin while the resin is melted in a large number of plastic pellets in a heated melter. There is the greatest advantage that quickness, airtightness, waterproofness, etc. can be improved with respect to the joining by the molten resin from the resin melt injection apparatus.
The first and second members resin-bonded by such a resin bonding apparatus can be provided as a bonding member that can be bonded extremely quickly.

  In particular, in the experimental example, when a large number of pellets are clogged in the cylinder, pressurizing or the like does not cause a large number of pellets filled in the cylinder to flow backward, and the pellets are pressed against each other. Thus, the pellets are melted by passing through a large number of melting holes communicating from the large opening on the inflow side to the small opening on the outflow side, and the resin can be melted well.

The pressed many pellets are not wasted at all, and can be directly fed into a large number of large openings on the inflow side of the melting holes of the melter. Therefore, a large number of pellets between the fixed or movable blocking portion and the inflow side surface portion of the melter can be sequentially fed. The pellet that is pressed between the closing portion and the inflow side surface portion of the melter and enters from the large opening on the inflow side of the melting hole is surrounded by the inner peripheral wall surface of the melting hole.
Thus, since the melting hole is a cone-shaped or constricted melting hole passage, the pressing force gradually increases with the movement toward the outflow side small opening side and is melted by heating to become small.

  The melter itself is heated to the melting temperature of the pellets by heating means, and the pellets are melted. At this time, the entire periphery of the pellet is in a state surrounded by the inner peripheral wall surface of the melting hole, and the pellet can be melted from the outer periphery to the center part in a substantially even balance. In addition, since the pellet body moves in the melting hole from the inflow side large opening toward the outflow side small opening, the container body has a large heat capacity. Can be maintained at a sufficient melting temperature while heating the pellets without being affected by the temperature of the molten pellets.

  And while the pellets are melted substantially uniformly from the outer periphery toward the center, they are pressed by a large number of pellets that enter one after the other from the inflow side large opening, and can move to the outflow side small opening of the melt hole. Melting of the pellets progresses, and most of the melted part is passed through approximately the middle in the axial direction (longitudinal direction) of the melt hole. Melting of the surrounding pellets progresses at an accelerated rate with the melting heat of the melter. . In the vicinity of the small opening on the outflow side, the pellets are completely melted at the maximum temperature and can be stored in the cylinder as a molten resin.

  Thus, the melter has a plurality of constricted melting holes in the main body, and the pellet storage area of the cylinder in the constricted melting holes heated to the melting temperature by the heating means. Since the pellets extruded inside enter from the large opening side inflow side, the pellets melt in a well-balanced manner and the heat capacity of the melter is large, so that a high temperature state can be maintained and melting is promoted. As a result, the melting rate is increased, and the molten resin is stored on the outlet member side.

  In particular, in the melter, the temperature of the resin reaches the maximum at the small opening portion on the outflow side by the heating means. The optimum temperature required immediately before injection and the maximum temperature can be set, and the resin is not deteriorated by setting the high temperature state to the minimum time, so that high-quality molding is possible. That is, the melter has a structure that can raise the resin to the optimum temperature immediately before injection in the last process in which the resin melts.

  Until it is injected into the adapter, the melter is once heated to a high temperature by the heating means, and the high temperature is maintained by a large heat capacity, and the molten pellet maintains a sufficient melting temperature without lowering the temperature. , A molten resin can be made with high quality pellets. When the molten resin is injected into the adapter, it immediately solidifies at the normal temperature peripheral walls of the first member and the second member, and the first member and the second member are joined to each other quickly and airtight. Etc. can be improved. Such a solidification rate is different for both the bond and the joint material.

  In the first aspect of the invention, in particular, when the coupling hole of the first member or the second member is formed as a female screw, the resin bolt coupling configuration can be manufactured almost instantaneously by the molten resin injection operation through the adapter. There is an advantage, and when it is desired to disassemble, etc., there is an advantage that the resin bolt cured by the resin bonding can be loosened and removed, and it can be returned to the original state. In the case of a hard synthetic resin, it can be firmly fixed. Furthermore, the adapter can be simply configured and can be provided at a low cost. The 1st, 2nd member resin-bonded with such a resin-bonding apparatus can have a favorable joint part.

According to the second aspect of the present invention, when the first member and the second member are to be separated and disassembled, there is an advantage that the resin bolt cured by the resin bonding can be loosened and removed. In particular, because of the metal nut, it can be firmly joined and returned to its original state. If the metal nut is not welded, there is an effect that the whole can be easily separated at the time of dismantling. According to the third aspect of the present invention, a resin nut (cap nut) coupling structure can be manufactured by mounting a metal bolt. The first and second members thus resin-bonded can also be good members. Later, the first member and the second member are separated,
When it is desired to disassemble, there is an advantage that the resin bag nut cured by the resin bonding can be loosened and removed. In particular, because of the metal bolt, it can be firmly joined or returned to its original state. If the metal bolts are not welded, it is easy to separate the whole when dismantling.

  The invention according to claim 4 has an advantage that the first member and the second member can be joined to each other without providing any coupling holes or the like for the first member and the second member. Even if the first member and the second member are joined at an appropriate interval, they can be joined well. Further, the first member and the second member can be joined by a round bar or a square bar as well as a plate material. The resin-bonded first and second members can be made orderly without any processing, and there is an advantage that a member from which resin bonding has been removed can be used as a new member.

  In the invention of claim 5, when the first member and the second member are joined by resin, if it is desired to temporarily separate and disassemble the first member and the second member later, the resin joining is performed. The cured resin can be used as a headless screw. In the case where it is desired to finally dismantle, since a molten resin is used, when the resin is heated to a temperature higher than the melting temperature of the resin, the maximum effect is achieved in that the bonding is released and disassembly and separation can be easily performed.

  In the invention of claim 6, there is an advantage that the robot factory can be manufactured so as to be capable of handling for 24 hours. In the invention of claim 7, there is an advantage that the resin can be satisfactorily bonded by avoiding the cooling by the first adapter. Thus, the 1st, 2nd member joined by resin can be provided as an orderly member. In particular, in the inventions of the first to seventh aspects, the first and second members can be disassembled by heating and melting the resin at the jointed portion so that it can be instantaneously decomposed and disassembled.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the main configuration of the present invention includes a resin melt injection apparatus A that injects a molten resin q and an adapter 8. The resin melt injection apparatus A and the adapter 8 are apparatuses for resin-bonding the first member 91 and the second member 92 to each other.

  The material of the first member 91 and the second member 92 can be metal, glass, resin, timber, etc., but generally there are many metals. The first member 91 and the second member 92 are often made of the same material, but may be made of different materials depending on the application. That is, aluminum and iron, iron and plastic, and the like.

  Since the resin bonding apparatus of the present invention has high injection performance, it can be used in a wide range of materials from low-temperature molten resins (general-purpose plastics, ABS, polyethylene, polypropylene, etc.) to high-temperature molten resins (engineering plastics, polyamide, polycarbonate, polyimide, etc.). Therefore, various selections can be made depending on the application. In addition, an appropriate color can be selected depending on the product.

  The resin melt injection apparatus A is shown in FIGS. The main structure is composed of a cylinder 1, a melter 2 for melting the pellets p, p,..., A driving means 3 for reciprocating the melter 2, a heating means 4 and the like.

  As shown in FIG. 1, the resin melt injection apparatus A is fixed to an end of an upper clip portion 97a provided on a column portion 96 on a base 95 of a small stand B (about 0.5 m to about 1 m) so as to be vertically adjustable. Further, the outlet member 5 below the cylinder 1 of the resin melt injection apparatus A is supported and fixed together with a fixing frame 97c for supporting and fixing the periphery of an upper adapter 81 (described later) provided at the tip of the lower clip portion 97b. It is configured. In particular, the lower clip portion 97b and the fixed frame 97c can withstand pressing from the lower side.

  As shown in FIG. 1, the lower adapter 82 is fixed on a pedestal 98a of an elevating device 98, on which a first member 91 and a second member 92 can be set. When the elevating device 98 is appropriately raised, the first member 91 and the second member 92 are held in a pressed state so as to match the upper adapter 81. In this state, the molten resin q is injected from the resin melt injection apparatus A. Hereinafter, since the resin melt injection apparatus A has a feature, this configuration will be described first, and then the adapter 8 will be described sequentially.

  An outlet member 5 is provided at the end (lower end in each drawing) of the cylinder 1 of the resin melt injection apparatus A, and the melter 2 and the closing portion 6 that reciprocate are provided therein. In the embodiment, the closing portion 6 is formed in an internal cylinder shape, and a plate-like closing surface 61 is provided at the tip (lower end in each figure), and is fixed in a sealed manner on the inner surface of the cylinder 1. . The driving means 3 of the melter 2 is provided with a reciprocating rod 34 slidably provided through the closing surface 61. A heat insulating material 61a made of a thick hard synthetic resin may be provided on the entire surface of the closing surface 61.

  That is, the outlet member 5 is attached to one end side (the lower end in FIG. 1) of the cylinder 1 in the axial direction (or also referred to as the longitudinal direction, the vertical direction in FIGS. 1, 2A and 2B). On the other end side (upper end in FIG. 1A) in the axial direction (upper end in the longitudinal direction), the blocking portion 6 as a cylinder is built. Further, the driving means 3 is mounted on the other end side (upper end in FIGS. 1A and 1B) in the axial direction (upper end in the longitudinal direction) via a cylindrical case 13, and the melting means is used by the driving means 3. The device 2 is configured to reciprocate (see FIGS. 1 and 2).

  The material of the cylinder 1 needs to be heated quickly, and iron or stainless steel with a high iron content is suitable. The cylinder 1 is composed of an elongated cylinder body 11 and a tubular supply pipe 12 connected from a pellet supply port 11a formed near the closing portion 6.

  The supply pipe 12 is configured to communicate with a hopper 18 for storing pellets p, p,. The supply pipe 12 is connected by a portion integrated with the cylinder 1 and a pipe formed in an appropriate arc shape. The cylinder main body 11 is a cylindrical member, and an inner side of the cylinder main body 11 has a substantially columnar space surrounded by an inner peripheral side surface 11b.

  The thickness of the cylinder body 11 is preferably about 2 mm. A large number of pellets p, p,... Can be charged into the hopper 18, and the charged pellets p, p,... Are fed into the cylinder body 11 from the pellet supply port 11 a through the supply pipe 12.

  Further, although not particularly shown, the supply pipe 12 may be provided with a screw conveyance or pneumatic device to forcibly introduce the pellets p, p,. Although the cylinder 1 has a circular cross section, the circle may be slightly deformed to be elliptical. In this case, accurate reciprocation is possible without the melter 2 having the same shape rotating.

  The outlet member 5 is mounted on one end side (lower end) of the cylinder body 11 in the axial direction (longitudinal direction). The outlet member 5 includes a nozzle part 51, a funnel part 52, and a connection part 53. The nozzle part 51 is composed of an injection tip 51a and a base part 51b [see FIGS. 1 and 5A].

  The injection tip 51a has a small diameter, and the base 51b has a slightly large diameter through a step. It may be the same diameter. An insertion hole 81 a is formed in the first adapter 81 of the adapter 7 so that the nozzle portion 51 can be stored properly. The connecting portion 53 of the outlet member 5 and the cylinder main body 11 are detachable with a structure having a screw structure (an outer screw, an inner screw). The material of the nozzle part 51 is preferably a material having good thermal conductivity, and specifically, beryllium copper or copper is desirable.

  The melting device 2 is formed by a plurality of melting holes 22, 22,... Formed in a substantially cylindrical body main body 21 (see FIGS. 1 to 3, 18 to 21, etc.). The material of the vessel body 21 is preferably a material having a large heat capacity and good heat conduction. Specifically, copper or beryllium copper is used. The vessel main body 21 is configured to be reciprocable (see FIGS. 1 to 3) inside the cylinder main body 11 of the cylinder 1, and is always disposed near the outlet member 5. [Refer FIG. 1 (A)].

  As shown in FIG. 18, the vessel main body portion 21 of the melter 2 is formed in a cylindrical shape as described above, and the side of the vessel main body portion 21 facing the plugging portion 6 and a large number of them. The surface on which the pellets p, p,... Flow is referred to as an inflow side surface portion 21a. The surface opposite to the inflow side surface portion 21a faces the outlet member 5, and the surface on the side from which the molten resin q flows out is referred to as an outflow side surface portion 21b.

  Further, the outer peripheral side surface of the vessel main body 21 is referred to as a circumferential side surface 21c. The vessel body 21 has a cylindrical shape as described above. The diameter D2a of the inflow side surface portion 21a and the diameter D2b of the outflow side surface portion 21b are the same as those of the circumferential side surface 21c along the axial direction. It is an exact cylindrical shape having the same diameter (see FIGS. 18A and 18B). Also, the melting device 2 in FIGS. 1 to 3 and FIG. 18 has the above-described accurate cylindrical shape.

である〔図１８（Ａ）参照〕。 That is,

[See FIG. 18 (A)].

  Next, the fusion hole 22 is formed along the axial direction (longitudinal direction) of the vessel body 21 (see FIGS. 1 to 3). More specifically, the melting hole 22 is a tunnel-shaped or pipe-shaped conical through-hole [see FIGS. 18B and 18C]. In the melt hole 22, the aforementioned conical through-hole is formed so that the cross-sectional shape at a plurality of arbitrary positions orthogonal to the hole forming direction is changed from a wide shape to a narrow shape. A hole having a gap such as a cone or a pyramid [see FIGS. 18B and 18C].

  In the present invention, in particular, a conical shape is preferable as the conical shape of the melting hole 22, and the diameter is formed so as to gradually decrease from large to small (see FIGS. 18B and 18C). As described above, since the melt hole 22 is a hole having a conical gap, the sizes of the openings at both ends of the melt hole 22 are different. Therefore, the large opening side of the melting hole 22 is referred to as an inflow side large opening 22a into which the pellets p, p,... Flow in (see FIGS. 4A, 4B, 18B and 18C).

  The small opening side of the melting hole 22 is referred to as an outflow side small opening 22b (see FIGS. 4A, 18B and 18C). That is, the melt hole 22 is a passage that communicates from the inflow side large opening 22a to the outflow side small opening 22b, and the cross section gradually becomes narrower from the inflow side large opening 22a toward the outflow side small opening 22b.

  And the inflow side large opening 22a is located in the inflow side part 21a side of the container main body part 21, and faces (or opposes) the blocking part 6 (see FIGS. 1 to 3). Moreover, the outflow side small opening 22b is located in the outflow side part 21b, and faces (or opposes) the outlet member 5 (refer FIG. 1 thru | or FIG. 3).

  As described above, the inflow side surface portion 21a of the melter 2 is provided with inflow side large openings 22a, 22a,... Of a large number of melting holes 22, 22,. Since the pellets p, p,... Flow into the inflow side large opening 22a facing the plugging portion 6, they are referred to as the inflow side of the melter 2.

  18 to 20, the outflow side surface portion 21b of the melter 2 is provided with outflow side small openings 22b, 22b,... Of a large number of melting holes 22, 22,. The outflow side surface portion 21b faces the outlet member 5 side and flows out the molten resin q in which the pellets p, p,... Are melted from the outflow side small opening 22b, and is therefore referred to as the outflow side of the melter 2. The melted state toward the inflow side and the outflow side of the melter 2 is shown in FIGS. 4 (A) and 4 (B).

  In the case where the melting hole 22 is a conical hole, the cross-sectional shape of each orthogonal portion along the axial direction (longitudinal direction) is a circular shape (see FIGS. 18B and 18C). The inflow side large opening 22a of the melting hole 22 is sized so that one whole pellet p can enter and at least a part (part) of the pellet p can enter. The specific size of the inflow side large opening 22a is a diameter that allows the pellets p, p,.

  The outflow side small opening 22b has a diameter of about 1 to 1.5 mm so that the pellets p, p,... The melting hole 22 has a substantially tapered cross-sectional shape along the axial direction (longitudinal direction). That is, when the shape is a pyramid along the axial direction (longitudinal direction) and the shape is a pyramid, the shape may be a quadrangular pyramid or a triangular pyramid. There is also a type that combines a quadrangular pyramid shape and a conical shape. In this type of melting hole 22, the inflow side large opening 22a of the conical melting hole 22 has a polygonal shape of a triangle or more, and the outflow side small opening 22b has a circular shape.

  FIGS. 19A and 19B show another embodiment of the melting hole 22 of the melting device 2, which is formed as a constricting melting hole. FIG. 19A is a second embodiment of the melting hole 22 of the melting device 2 and gradually increases from the large diameter to the small diameter so that the inflow side large opening 22a becomes the outflow side small opening 22b. However, it is formed as a plurality of cylindrical portions 22c, 22c, and the end portion of the cylindrical portion 22c corresponds to the outflow side small opening 22b, or only the end portion is formed as the outflow side small opening 22b [FIG. (See (A)).

  FIG. 19B is formed as a melting hole 22 whose tip is narrowed. 3. A third embodiment of the melting hole 22 of the melting device 2, wherein the conical hole has a diameter from a large diameter to an intermediate diameter so as to be changed from the inflow side large opening 22a to the outflow side small opening 22b. And only the end is formed as the outflow side small opening 22b.

  FIG. 20A is also formed as a melt hole 22 whose tip is narrowed. In the fourth embodiment of the melting hole 22 of the melting device 2, the large-diameter cylindrical portion 22d as the inflow side large opening 22a is end so that the inflow side large opening 22a becomes the outflow side small opening 22b. The outflow side small opening 22b is formed only at the end portion.

  In FIG. 20B, the inflow side large opening 22a of the melting hole 22 is formed in a circular cross section, and the inlet portion of the inflow side large opening 22a is adjacent to each other with a dish-like chamfer 22a1 formed. A portion serving as a boundary between the dish-shaped chamfers 22a1 and 22a1 of the inflow side large opening 22a may be formed as a blade shape 22s. Due to the presence of the blade shape 22s, the pellet p is often crushed and finely separated at the position of the blade shape 22s, and the pellet p becomes easier to enter through the inflow side large opening 22a, thereby promoting the melting of the pellet p. It also has an effect.

  The drive means 3 includes a motor drive unit 31 with a reduction gear, a pinion gear 32, and a rack shaft 33. Alternatively, although not shown, there is also a drive means 3 in which the rod reciprocates by driving a motor drive unit 31 with a speed reducer and a ball screw and a ball screw nut drive. A reciprocating rod 34 is connected to the tip of the rack shaft 33 or the rod end.

  As shown in FIG. 1, the reciprocating rod 34 is passed through substantially the center of the closing portion 6, and the tip thereof is connected to the melter 2. The rear side of the rack shaft 33 is slidably provided on the motor case 38 of the motor drive unit 31. The reciprocating rod 34 is made of iron or stainless steel.

  The motor drive unit 31 is configured by a brushless motor, a stepping motor, or the like, and is capable of high-precision drive control. In consideration of the material of the pellet, the time of the melting process and the injection process of the molten resin q Time can be separated and controlled. As a result, a sufficient time for melting the resin can be ensured, and the injection process of the molten resin q can be performed very quickly and efficiently in a short time.

  For example, by setting the melting process time to about 30 to about 60 seconds and the molten resin injection process time to about 1 second, the maximum resin bonding time after injection can be achieved very quickly and efficiently in a short time. There are advantages. In particular, the brushless motor is suitable for extending the melting process time and controlling the resin bonding time repeatedly and accurately.

  The heating means 4 is a structural member that heats the melting device 2 from the outer peripheral surface of the cylinder body 11, and is configured in a cylindrical shape so that the thermal conductivity to the melting device 2 is good. Specifically, a sufficient amount of heat can be obtained with an IH heater or the like configured in a winding shape.

  The heating means 4 serves to heat the melter 2 that reciprocates in the cylinder body 11 of the cylinder 1. Specifically, the heating means 4 is preferably an electromagnetic induction device, that is, an IH (Induction Heating) coil, and an IH coil is wound around a heat insulating material coil bobbin made of resin or ceramic.

  The bobbin shape is set so that the distance between the IH coil and the outer peripheral side surface of the cylinder body 11 is optimal. The input power is preferably variable from 0 to 1 Kw by the control device. A thermocouple is attached to the cylinder 1 so that the temperature of the cylinder 1 can be set to a set value. A band heater may be used as another type of the heating means 4. Furthermore, the heating means 4 is not limited to the one described above, and any other heating device that can be used in the present invention may be used.

  Although the heating means 4 is fixed to the cylinder body 11, the heat capacity of the melter 2 can maintain a sufficient heat source even if the driving means 3 reciprocates. . This is because it is normally set as the fixed position approaching the position of FIG. 1A, that is, the five outlet members. Even if the melter 2 moves in the return path (melting process) in the pellet storage region W, it immediately moves from the state to the forward path (injection process), and the melter 2 is easily cooled in the heating state. Therefore, a sufficient heating amount can be obtained and a predetermined temperature can be maintained.

  Moreover, about the said melter 2, the heat insulation process is provided as needed. This point will be specifically described. As shown in FIG. 18 (A), the reciprocating rod 34 of the driving means 3 is loosely inserted into the central through hole 21d passing through the centers of the inflow side surface portion 21a and the outflow side surface portion 21b of the melter 2. . That is, the inner diameter of the center through hole 21d is formed slightly larger than the diameter of the reciprocating rod 34 and is configured not to contact. Further, concave portions 21a1 and 21b1 are formed at the center positions of the inflow side surface portion 21a and the outflow side surface portion 21b of the melter 2, respectively.

  As shown in FIG. 18 (A), in the recesses 21a1 and 21b1, the reciprocating rod 34 is provided with heat insulating materials made of ceramic or polyimide, or stainless steel disk-like support pieces 25 and 25. It is fixed to. Specifically, after one support piece 25 is inserted into the reciprocating rod 34, the tip end side of the reciprocating rod 34 is passed through the central through hole 21 d of the melter 2. The one support piece 25 is disposed in the concave portion 21a1 of the inflow side surface portion 21a of the melter 2.

  In this state, as shown in FIG. 18A, the collar member 72 into which the other support piece 25 and the disc 71 are inserted is inserted into the distal end side small diameter portion 34a formed in the reciprocating rod 34. The The collar member 72 is made of iron or stainless steel. Further, a nut 34 c is screwed into the threaded portion 34 b of the distal end side small diameter portion 34 a of the reciprocating rod 34, and the fuser 2 is fixed to the reciprocating rod 34. That is, the melter 2 is fixed to the reciprocating rod 34 via the support pieces 25, 25 without directly contacting the reciprocating rod 34. For this reason, the reciprocating rod 34 can be in a state where there is almost no heat conduction of the melting device 2. That is, it can be in a heat cutoff state.

  With these structures, the heat source generated in the melter 2 is configured not to conduct heat to the metal reciprocating rod 34 (mainly stainless steel or the like) inside the cylinder 1. As described above, the purpose of the heat insulation of the melter 2 is to use the heat quantity of the melter 2 only for melting the pellets p, p,. Therefore, a heat insulating material (support piece 25 or cylindrical collar 35) is interposed between the melting device 2 and the reciprocating rod 34.

  In particular, when the hole diameter of the outflow side small opening 22b of the melter 2 is much smaller than the inflow side large opening 22a [see FIG. 1 to FIG. Even when the molten resin q is pressed through the outlet member 5 by the forward path process, the surface area of the outflow side surface portion 21b of the melter 2 is much larger than the area of the entire outflow side small opening 22b, The ratio of the molten resin q flowing backward from the hole portion of the opening 22b is extremely reduced, and the molten resin q can be favorably injected from the outlet member 5 by being pressed. Thus, the injection process of the molten resin q may be performed without providing the opening / closing valve 7 in the melter 2.

  As the internal structure of the melter 2, an on-off valve 7 is provided as necessary (see FIGS. 1 to 3). That is, the on-off valve that opens the inflow side large opening 22a or the outflow side small opening 22b of the melter 2 in the return path process and closes the inflow side large opening 22a or the outflow side small opening 22b of the melter 2 in the outbound path process. 7 is provided.

  Specifically, the on-off valve 7 is configured to close the front end side of the melter 2 during the forward pass process or to release during the return pass process. Specifically, as shown in FIGS. 18 to 20, the on-off valve 7 includes a disc 71 and a collar member 72 with a collar 73. The collar member 72 with the flange 73 is located on the front surface of the outflow side surface portion 21b of the melter 2 and is disposed at the tip of the reciprocating rod 34 penetrating through the center of the melter 2 via the collar member 72. Thus, it is provided so as to be slightly movable back and forth between the flange 73 and the outflow side surface portion 21b.

である。これは、復路工程の時に、溶融樹脂ｑが前記開閉弁７の外縁より流れやすくするためである。 The diameter D7 of the disc 71 is smaller than the diameter D2b of the outflow side surface portion 21b [see FIG. 16 (A)].
That means

It is. This is to make the molten resin q flow more easily than the outer edge of the on-off valve 7 during the return path process.

  Briefly describing the above-described configuration, the on-off valve 7 is provided between the outlet member 5 and the melter 2 and is a disk that contacts and separates from the outflow side small opening 22b of the melter 2. 71, and the disk 71 is formed to have a diameter smaller than the diameter of the melter 2.

  As shown in FIGS. 18B and 18D, the disk 71 in the on-off valve 7 is formed with a large number of through holes 71a, which are formed in the outlet side small opening 22b of the melter 2. The guide pins 71b projecting from the disc 71 are formed so as to be inconsistent with the positions, and can be loosely inserted between the holes 21p formed in the melter 2.

  In another embodiment of the on-off valve 7, as shown in FIG. 18 (E), the disc 71 is formed without any number of through holes 71a. That is, only the disk 71 without holes is formed, and the disk 71 is formed with a diameter smaller than the diameter of the melter 2. In the case of this embodiment, all the molten resin q flows from the outer edge of the on-off valve 7 during the return path process.

  When the melter 2 with the on-off valve 7 is injected into the adapter 8 during the injection process, the molten resin q in the outlet member 5 may also become a high pressure, and the reverse flow Therefore, the on-off valve 7 is always configured to be elastically biased in the direction of the melter 2 by an elastic body 75 as a compression spring.

  Although another embodiment of the disk 71 of the on-off valve 7 is not shown, it is formed to be equivalent to the diameter D2b of the outflow side surface portion 21b of the melter 2, and a plurality of locations (for example, the circumferential edge of the disk 71 (for example, A notch through which the molten resin q flows out may be formed at the four locations). The notch is formed in a U shape, a U shape, or the like.

  In the collar member 72 shown in FIG. 18A, an inner screw is formed on the inner cylinder side to be screwed into the threaded portion 34b of the distal end side small diameter portion 34a. Further, as shown in FIG. 19A, the threaded portion of the collar member 72 itself is screwed into the distal end side small diameter portion 34a, so that the nut 34c is unnecessary, and the reciprocating rod 34 is removed. The melter 2 is fixed to [see FIG. 19 (B) and FIG. 20 (A)].

  With such a configuration of the collar member 72 and the on-off valve 7, the disc 71 can be slightly contacted and separated between the collar 73 of the collar member 72 and the surface of the melter 2. Specifically, when the thickness of the circular plate 71 is t, the thickness between the ridge and the surface of the melter is the thickness t + α, and the contact / separation movement is exhibited within the range of α [FIG. (See (A)). This is the same movement even when an elastic body 75 as a compression spring is provided.

  The pellet melting process and theory will be described below. First, in the stage before the melting process, as shown in FIG. 3A, pellets p, p,... From the pellet supply port 11a are placed in the pellet storage area W in the cylinder 1 before the inflow side surface portion 21a of the melter 2. It is stored on the side. The pellet storage area W is provided between the rear part of the melter 2 and the closing part 6 when the injection process in the cylinder 1 is finished, and the pellet supply port 11a is located at the rear part position of the pellet storage area W. Is provided.

  When the melting process is turned ON, a large number of pellets p, p,... Contained in the pellet storage area W by the return path process by the driving means 3 are converted into the melter as shown in FIG. 2 is compressed between the inflow side surface portion 21a and the closing portion 6 and returns to the hopper 8 side, but in reality, the pressing force f, are generated in an extruded state, and flow into the melt holes 22, 22,... from a large number of inflow-side large openings 22a, 22a,... [FIG. 3 (B), FIG. 4 (A)] reference〕. As described above, the inflow side large opening 22a has such a size that at least a part (part) of each pellet p enters.

  Normally, the inflow-side large opening 22a is sized so that the entire average size pellet p enters the inflow-side large opening 22a (see FIG. 4A). The pellets p, p,... Entering the melting holes 22, 22,... Are pressed toward the outflow side small opening 22b by the pellets p, p,. 4 to maintain the temperature at which the pellet p is melted.

  Accordingly, the pellet p entering from the inflow side large opening 22a melts toward the center of the pellet p as it moves from the inflow side large opening 22a toward the outflow side small opening 22b [see FIG. 4A]. The pellet p is set so that the periphery of the pellet p is substantially uniformly surrounded by the inner peripheral wall surface of the melting hole 22 in the initial state where the pellet p starts to enter the large opening 22a.

  As the pellet p moves through the melting hole 22 toward the outflow side small opening 22b, the size is gradually reduced while being melted (see FIG. 4A). Even if the pellet p moves while melting toward the outflow side small opening 22b side, the melting hole 22 is gradually narrowed, so that the periphery of the pellet p that has been melted and reduced is uniformly surrounded. doing. Therefore, the pellet p is melted quickly.

  In other words, the periphery of each pellet p is substantially evenly surrounded by the inner wall surface of the melting hole 22 and always maintains a state of being close to or in contact with the inner wall surface (see FIG. 4A). Then, as the melting of the pellet p proceeds, it further proceeds to a narrow portion of the melting hole 22 to promote the melting of the pellet p. Moreover, since the pellet p is melted and liquefied inside the melting hole 22, the melting of the pellet p fed later is further promoted by the heat of the already liquefied pellet pa [see FIG. 4 (A)]. ].

  In addition, as shown in FIG. 19A, when the molten hole 22 is formed so that the tip is narrowed by the presence of the cylindrical portions 22c, 22c, the pellet is pressed on the outlet side of the molten hole 22. However, the same action as that of the conical melting hole 22 can be exhibited by melting by the heating force. Such stepwise formation can provide a cheaper process compared to the conical process.

  Further, as shown in FIG. 20A, the large-diameter cylindrical portion 22d as the inflow-side large opening 22a is formed to the end, and the outflow-side small opening 22b is formed only on the outflow side. Thus, the pellet can be pressed on the back side and melted by a heating force to exhibit the same effect as a conical melting hole [see FIG. 4 (B)]. Even such hole drilling can be cheaper.

  In this way, as the pellet p moves from the inflow side large opening 22a of the melting hole 22 toward the outflow side small opening 22b, the melting progresses, and the melting is completed in the vicinity of or near the outflow side small opening 22b. The liquid is completely liquefied [see FIGS. 3B, 4A and 4B]. The pellet p becomes the completely liquefied molten resin q, and is stored in the cylinder 1 from the small outlet 22b on the outlet side as shown in FIG.

  As described above, a pressing force is generated between the pellets p, p,. The pellet p entering from the large opening 22a is always surrounded by the inner peripheral wall surface of the melting hole 22 in the process toward the outflow side small opening 22b. Therefore, the pellet p is melted through the heating means 4 and, as shown in FIG. The molten resin q is stored in 1. The stroke amount L may be equal to the pellet storage area W.

  A large number of pellets p, p,... Can be melted only in a necessary amount, so that the material is not exposed to thermal and mechanical stress in the cylinder body 11 for a long time. Therefore, a high-quality resin molded product can be obtained. In addition, the injection apparatus according to the present invention has high melting efficiency and does not require the addition of more materials than necessary, so that the entire apparatus is miniaturized, saving power and resources. In addition, the fact that the high temperature state of the resin can be shortened to the minimum time by achieving the injection proper temperature and the maximum temperature in the final melting process immediately before injection can also achieve high quality resin molding.

  In the above description, a large number of pellets p are continuously supplied from the pellet supply port 11a. However, as shown in FIG. 1, a predetermined amount of pellets p may be supplied. Specifically, a shutter mechanism 16 is provided. The shutter mechanism 16 includes a shutter plate 16a and a drive source 16b such as a solenoid for driving the shutter plate 16a up and down.

  The lower end portion of the shutter plate 16 a is inserted into a groove portion 12 a formed at the base portion of the supply pipe 12 to close the pellet supply port 11 a, and a flow of a large number of pellets p flowing into the supply pipe 12. Is configured to shut off. In the case of such a shutter mechanism 16, the pellet p supplied from the hopper 18 is controlled by controlling the time for opening and closing the shutter plate 16a in consideration of the flow speed and flow time of a large number of pellets p. Can be controlled to an appropriate amount.

  Thus, by melting and injecting the desired melting amount of the pellet p, there is an effect that these operations can be made orderly. Further, since the melter 2 reciprocates from the five outlet members to the vicinity of the closing portion 6 in the cylinder 1, it is integrally formed up to the vicinity of the closing portion 6, and the same diameter as the cylinder 1 from this position. A case 38 of the motor drive unit 31 is provided. The inner cylinder portion as the closing portion 6 is fixed in a sealed manner in the case 38.

  Next, the configuration of the adapter 8 will be described. The basic configuration of the adapter 8 is composed of a first adapter 61 and a second adapter 82. As shown in FIGS. 5A to 5C, the first embodiment of the adapter 8 includes a first adapter 81 and a second adapter 82. The first adapter 81 includes the resin melt injection device. An insertion port 81a into which the nozzle portion 51 through which the molten resin q generated in A is injected is formed.

  On the back surfaces of the first adapter 81 and the second adapter 82, the escape holes of the molten resin q are prevented while closing the coupling holes 911 and 921 respectively drilled in the first member 91 and the second member 92 for resin bonding. It has blocking surfaces 81b and 82b as surfaces. Specifically, when the upper and lower surfaces of the first member 91 and the second member 92 are flat surfaces, the blocking surfaces 81b and 82b are simply formed as flat surfaces.

  In the case of the adapter 8 of the first embodiment, the back surface (lower surface) of the first adapter 81 and the back surface (upper surface) of the second adapter 82 are only formed with the blocking surfaces 81b and 82b as flat surfaces. Therefore, expansion holes 911a and 921a for preventing detachment and tapered holes 911b and 921b are formed in the coupling holes 911 and 921 respectively formed in the first member 91 and the second member 92.

  In the case of the embodiment of FIG. 5, the case has been described in which the diameter of the coupling holes 911 and 921 is larger than the diameter of the injection port 51 a of the nozzle portion 5. FIG. 15 shows a case where the diameters of the coupling holes 911 and 921 are smaller than the diameter of the injection port 51a. This is a modification of the adapter 8 according to the first embodiment. Also in this case, the first member 91 and the second member 92 are provided with the coupling holes 911 and 921 and tapered holes 911b and 921b for preventing the detachment. The first adapter 81 is formed with an insertion port 81a into which the nozzle portion 51 into which the molten resin q generated by the resin melt injection apparatus A is injected.

It has blocking surfaces 81b and 82b as surfaces to prevent. Further, when the diameter of the coupling holes 911 and 921 is smaller than the diameter of the injection port 51a, the first adapter 81 may not be necessarily required. However, when the molten resin q is injected and bonded, a relatively high pressure is applied. Therefore, it is important that the first adapter 81 and the second adapter 82 are firmly fixed so as not to be separated from each other.

  In the case of a modification of the adapter 8 of the first embodiment, as shown in FIG. 6, a brass screw projection 82 c and a minus screw projection 82 d are slightly formed on the back surface of the second adapter 82, and the other surfaces Each has a closed surface 82b as a flat surface. In this case, the coupling holes 911 and 921 respectively drilled in the first member 91 and the second member 92 for resin bonding are formed as screw holes.

  In this way, when the first member 91 and the second member 92 are resin-bonded, when it is desired to temporarily separate and disassemble the first member 91 and the second member 92 later, the resin The bonded and cured resin can be used as a headless screw. When it is desired to finally disassemble, the molten resin q is used. Therefore, when heated to a temperature equal to or higher than the melting temperature of the resin, the maximum effect is achieved in that the bonding is released and disassembly and separation can be easily performed.

  As shown in FIG. 7A, the second embodiment of the adapter 8 includes a first adapter 81 and a second adapter 82. The first adapter 81 is generated by the resin melt injection apparatus A.

A concave portion 81c is provided which forms a bulging portion corresponding to a bolt head having a diameter larger than the diameters of the coupling holes 911 and 921. A flat surface other than the concave portion 81c is formed with a closing surface 81b as a surface for preventing the molten resin q from escaping.

  The second adapter 82 is formed with a flat surface that only blocks the coupling hole 921 as a screw hole drilled in the second member 92, and a blocking surface 82b is formed as a surface that prevents the molten resin q from escaping. Has been. In this case, the first member 91 and the second member 92 are joined by resin bolts. In the case where it is desired to disassemble the resin bolt, there is an advantage that the resin bolt cured by the resin bonding can be loosened and removed, and it can be returned to the original state.

A blocking surface 81b is formed as a surface that blocks 911 and prevents escape of the molten resin q. 7C, a hard synthetic resin heat insulating material 85 is interposed between the nozzle portion 51 and the nozzle portion 51 is clogged because it is difficult to cool the molten resin q. It may be configured to prevent this.

  The second adapter 82 is provided with a recess 82e that closes the coupling hole 921 drilled in the second member 92 and forms a bulging portion corresponding to a bolt head having a diameter larger than the diameter of the coupling hole 921. ing. A flat surface other than the recess 82e is formed with a blocking surface 82b as a surface for preventing the molten resin q from escaping. Also in this case, the first member 91 and the second member 92 are joined by resin bolts. In the case where it is desired to disassemble the resin bolt, there is an advantage that the resin bolt cured by the resin bonding can be loosened and removed, and it can be returned to the original state.
