Description

  The present invention relates to an automatic packaging machine for manufacturing a package in which a solid bag is filled in a resin film packaging bag, and more particularly to a raw material supply device of an automatic packaging machine for supplying a solid material.

  Conventionally, an automatic packaging machine capable of producing a package containing a large amount of raw materials at a high speed has been demanded. A rotary automatic packaging machine is known as one of such automatic packaging machines that can be manufactured at high speed. In this rotary automatic wrapping machine, a long resin film (wrapping film) unwound from a film coil is folded by a film guide while being moved in the horizontal direction, and the resin film is introduced into a turntable. Many sealing bars (side seal devices) arranged around the turntable hold the resin film while forming width seals (side seals) at regular intervals on the introduced resin film. Thus, a packaging bag is formed between the resin films that are sequentially folded, and is divided into a large number of packaging bags.

  A large number of filling chutes swivel between the sealing bars adjacent to each other and are inserted into a packaging bag between the resin films that are sequentially folded. When the raw material is supplied from the raw material supply device, this raw material is sent to the packaging bag between the resin films by a large number of filling chutes, and a predetermined amount of the raw material is filled in the packaging bag. After filling the raw materials, a large number of filling chutes are removed from the resin film packaging bag, and the sealing bar is removed from the resin film. The resin film in which the packaging bag is filled with the raw material is sealed by heat sealing (top sealing) on the upper edge thereof. The sealed resin film after filling is cut and perforated at the width seal portion, and is sealed for each package. Such conventional rotary automatic packaging machines are disclosed in, for example, Patent Document 1, Patent Document 2, and the like.

  Today, instant noodles and the like use a variety of foodstuffs, that is, a package filled with “gakusan” foodstuffs. As one form of the ingredients of the “grins”, there is a form in which a dry solid, that is, the ingredients are dried. Conventionally, since it is difficult to quantitatively count solids by a machine and put them into a package, the dried solids are manually scooped up and chopped and put into an automatic packaging machine. A method for producing a package filled with a solid material at a high speed using a rotary automatic packaging machine has been attempted regardless of such a manual operation.

Conventional rotary type automatic packaging machines have used raw materials such as a fixed amount of powder to squeeze a fixed amount. As described above, in the conventional rotary automatic packaging machine, the raw material is quantitatively filled only by punching. Therefore, when counting and filling the dried solid matter, a device for that is required. As an example, the dried solid matter can be put into a rotary automatic packaging machine by a machine using a raw material supply apparatus that supplies the dried solid matter as follows.
This raw material supply apparatus inputs the dried solid material from the raw material hopper in which the dried solid material is stored into a linear feeder. The linear feeder receives the solid material dried from the raw material hopper in a lump state, and separates the dried solid material lumped into the lump into the shooter. This conventional linear feeder is shown in FIG.

As shown in FIG. 6, the conventional linear feeder 200 is configured by a trough shape having a substantially V-shaped cross section. Therefore, the solid material 201 dried in a lump cannot be unwound in the lateral direction on the left and right, and it is only possible to loosen the dried solid material layered vertically on the front and back. Therefore, since the dried solid 201 is accelerated only in the front-rear direction, the moving speed of each dried solid 201 increases as it is transferred to the tip of the linear feeder 200. Therefore, it is difficult to adjust the amount of the dried solid 201. Furthermore, the dried solid mass only loosens into smaller masses, or even if loosened, gaps are likely to occur between the individual dried solids 201. For this reason, it becomes difficult to averagely put the dried solid material 201 loosened in the filling shooter, and the amount cannot be adjusted to a constant amount.
JP 2001-199402 A JP 2001-122208 A

Thus, when filling and packaging solids with a conventional rotary type automatic packaging machine, the solids accelerate and the solids are difficult to average on average. There is a problem in that the number of objects varies, and the amount of solids supplied to the filling shooter cannot be adjusted to a certain amount.
The present invention has been made to solve such problems, and an object of the present invention is to provide a raw material supply device for an automatic packaging machine capable of adjusting the amount of solids to be supplied to a constant amount.

The raw material supply device of the automatic packaging machine according to the present invention is a solid material as the raw material in an automatic packaging machine that forms a packaging bag by sealing a packaging film and continuously fills the packaging bag with the raw material. A material hopper for supplying an aggregate composed of a plurality of the solid materials, and feeding the solid material into the automatic packaging machine by transferring the aggregates supplied from the raw material hopper A feeding member that has a long shape and allows the assembly to pass in a row in a longitudinal direction, and a midway portion between a front end and a rear end of the passage member. And a dropping mechanism for dropping the solid material that has overlapped on the solid material in a single row under the passage member.
In such a configuration, the input feeder can remove the solids that are superimposed on the solids in a single row from the aggregate, so that the solids can be in a single row. As a result, the solids arranged in a row can be supplied to the automatic packaging machine, and the amount of the supplied solids can be adjusted.

  Furthermore, the raw material supply apparatus of the automatic packaging machine according to the present invention includes a return mechanism that inputs the solid material dropped by the dropping mechanism into the passage member and returns it. Thereby, the solid substance supplied to an automatic packaging machine can be utilized efficiently.

  Preferably, the return mechanism receives a first tray slider for receiving the dropped solid, a belt conveyor for lifting an aggregate received by the tray slider, and an aggregate lifted by the belt conveyor. And a second tray slider to be put into the passage member.

  Furthermore, the passage member has an inclination such that an input side end portion into which the solid material is charged into the automatic packaging machine is higher than a supply side end portion to which the aggregate is supplied from the raw material hopper. . Thereby, since the speed | rate of the solid substance at the time of throwing into an automatic packaging machine can be suppressed, control of a solid substance becomes easy and it becomes possible to adjust the quantity of the solid substance supplied to a fixed quantity.

In addition, the input feeder has a plurality of the passage members arranged side by side.
Alternatively, the input feeder includes a first passage member provided with a first dropping mechanism and a second passage member arranged below the first passage member and provided with a second dropping mechanism. The first dropping mechanism drops the overlapped solid matter under the first passage member, and the second passage member is dropped from above by the first dropping mechanism. It is intended to receive solids.
In this case, since the amount of the solid matter can be adjusted for each of the first passage member and the second passage member, the amount adjustment of the supplied solid matter can be further simplified.

  Preferably, the passage member has a substantially V-shaped cross section substantially perpendicular to the longitudinal direction, and the dropping mechanism is a cut portion cut along the substantially V-shaped slope. Thereby, a dropping mechanism can be formed simply.

On the other hand, the rotary automatic packaging machine according to the present invention includes a side seal device that forms a side seal by thermocompression bonding in the width direction with respect to a packaging film folded in the center while being transported in the horizontal direction, and A raw material supply device that puts the solid material into a plurality of packaging bags between the side seals, a turntable that rotates the side seal device, and a top of the packaging bag filled with the solid material by thermocompression bonding And a top seal device for forming a seal, and the devices are linked to make a large number of packages.
In such a configuration, when a rotary automatic packaging machine is used, the package can be packed and filled at a high speed. A packaged package can be manufactured.

  ADVANTAGE OF THE INVENTION According to this invention, the raw material supply apparatus of the automatic packaging machine which can adjust the quantity of the solid substance supplied to a fixed quantity can be provided.

  The best mode for carrying out the present invention will be described using a rotary automatic packaging machine. However, the present invention is not limited to this, and any automatic packaging machine for filling and packaging a solid material may be used. Moreover, the raw material supply apparatus in the automatic packaging machine according to the present invention uses a linear feeder, and puts solid materials along the linear feeder without overlapping each other and puts a certain amount into the packaging bag. .

In addition, as a solid substance with which a packaging bag is filled, it demonstrates using dry solids (dry solid substance), such as dry porridge, dry raising, dry chopped onion, dried Takano tofu, dried wakame, etc., for example. However, the present invention is not limited to this, and it may be a quantum solid raw material that can be separated and counted, such as a solidified powder that can be counted. In addition, the solid material may be a raw material that can be counted regardless of the size of the lump.
The best mode for carrying out the present invention will be described below with reference to the drawings.

Embodiment 1 of the Invention
First, the overall configuration of the rotary automatic packaging machine according to the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a front view showing a rotary automatic packaging machine according to the present invention. FIG. 2 is a top view showing the raw material supply apparatus of the rotary automatic packaging machine according to the present invention.
In FIG. 1, a rotary automatic packaging machine (hereinafter abbreviated as “automatic packaging machine”) according to the present invention is generally indicated by reference numeral 1. In FIG. 1, 2 is a rewinding reel, 3 is a film guide, 4 is a turntable, 5 is a side seal device, 6 is a raw material supply device, 7 is a filling chute, 8 is a guide roll, 9 is a top seal device, Reference numeral 10 denotes a notch device, and 11 denotes a cutter device.

  Further, the film coil 120 is obtained by winding the packaging film 121 in a coil shape around the same axis. The packaging film 121 is made of a transparent or translucent material, for example, a base film such as PET, or a heat seal film such as polyethylene having a melting point lower than that of the base film. The packaging film 121 may have a three-layer structure of a base film, an intermediate film, and a heat seal film.

  As shown in FIG. 1, the packaging film 121 is pulled out from the film coil 120 while being back tensioned by the coil rewinding reel 2. The drawn packaging film 121 continuously flows upward in the figure, and is folded into two in a U shape at the center by the film guide 3. The folded packaging film 121 is introduced into the turntable 4 from the tangential direction of the turntable 4.

  On the turntable 4, the side seal device 5 that forms the side seal 124 is disposed apart by a certain distance. When the packaging film 121 is positioned at a predetermined position, the side sealing device 5 performs heat sealing in the width direction of the packaging film 121 and locally melts the heat sealing film. As a result, the melted heat seal films of the two-fold packaging film 121 are pressure-bonded to form a side seal 124. In this way, a plurality of packaging bags 122 sandwiched between the side seals 124 are formed on the folded packaging film 121. A filling chute 7 is inserted into the plurality of packaging bags 122.

  The raw material supply device 6 inputs a dry solid 130 as a raw material from the raw material hopper 60 to the circular feeder 61. At this time, the dry solid 130 is put in a large lump. The dried solid material 130 charged into the circular feeder 61 is loosened into a relatively smaller lump in the circular feeder 61 than when it was charged, and is sent to the linear feeder 62 in this state. As will be described in detail later, the linear feeder 62 aligns the dry solids 130 in a row by sieving the dry dry solids 130 sent from the circular feeder 61 from the cut portions 631. The state is charged into the filling chute 7. At this time, the dry solid 130 is put into the filling chute 7 via the collective bracket 70 fixed on the filling chute 7. In this way, a plurality of types of dry solids 130 are sequentially charged into the filling chute 7 (see FIG. 2). The filled dry solid 130 is filled in the packaging bag 122 through the filling chute 7 because the filling chute 7 is disposed on the packaging bag 122.

  The packaging bag 122 filled with the dry solid material 130 is rotated by the rotation operation of the turntable 4, the transfer direction is changed by the guide roll 8, and then linearly transferred to the top seal device 9. When the top seal device 9 heats the upper edge portion of the packaging film 121 with the preheating seal bar 91, the heat seal film on the upper edge portion of the packaging film 121 is melted. In this state, the top seal roller 92 pressurizes the edge portion thereof, whereby the heat seal films of the bi-fold packaging film 121 are pressure-bonded to form the top seal 125. Thereby, the packaging bag 122 is sealed.

  Thereafter, the packaging bag 122 is sent to the notch device 10 by the extrusion of the top seal roller 92. The packaging film 121 is nipped by the notch guide 100 of the notch device 10, and the top seal 125 is partially cut by the notch cutter 101 in this nipped state. Thereby, a notch is made in the packaging film 121. The cutter device 11 cuts the side seal 124 or perforates the side seal 124, whereby the plurality of packaging bags 122 are packaged into a package 123 that packages the dry solid 130.

Next, the raw material supply apparatus 6 of the automatic packaging machine 1 according to the present invention will be described. A configuration example of the raw material supply device 6 is shown in the top view of FIG. As shown in FIG. 2, the raw material supply device 6 includes a raw material hopper 60, a circular feeder 61, and a linear feeder 62.
The raw material hopper 60 puts the lump of the dried solid material 130 supplied from the supply port 600 by the operator into the circular feeder 61 from the input port 601 protruding substantially horizontally. That is, the raw material hopper 60 changes the transfer direction of the dry solid 130 supplied substantially vertically downward to a substantially horizontal direction. Moreover, the raw material hopper 60 vibrates in the projecting direction of the charging port 601 projecting substantially horizontally from the raw material hopper 60 by a vibration device (not shown), and the mass of the dry solid material 130 is sent by this vibration.

  The circular feeder 61 loosens the lump of the dried solid material 130 introduced from the raw material hopper 60 and sends the loosen lump of dried solid material 130 of the lump to the linear feeder 62. The circular feeder 61 has a substantially cylindrical shape, a cavity is formed inside, and an upper surface is opened. The circular feeder 61 is provided with a transfer shelf (not shown) for feeding the dried solid material 130 on a substantially cylindrical curved side surface. The transfer shelf (not shown) is formed so that a substantially cylindrical curved side surface is spirally raised from the bottom surface to the top surface. Further, the circular feeder 61 is provided with a vibration device (not shown), and this vibration device gives vibration to the circular feeder 61 in the direction of going up the spiral transfer shelf.

  The lump of the dried solid material 130 from the raw material hopper 60 is put into a cavity inside the circular feeder 61 and moves in the direction of the curved side surface of the circular feeder 61 by vibration of a vibration device (not shown). The lump of the dried solid material 130 that has moved is further broken by vibrations into a smaller lump while moving on a transfer shelf (not shown), and sent from the bottom surface to the top surface. The circular feeder 61 is put into the linear feeder 62 from a loading port 611 protruding along the curved side surface of the circular feeder 61. Since the dry solid material 130 that has become a lump in the circular feeder 61 can be loosened into a small lump, the circular feeder 61 can be used to save space in the raw material supply device 6.

Next, the linear feeder 62 of the raw material supply device 6 will be described in detail with reference to FIG. FIG. 3 shows a configuration example of the linear feeder 62 of the raw material supply apparatus 6. FIG. 3A is a top view of the linear feeder 62 observed from above. 3B is an end view of the linear feeder 62 observed from the left side of FIG. 3A, and FIG. 3C is a side view of the linear feeder 62 observed from the lower side of FIG.
As shown in FIG. 3, the linear feeder 62 includes troughs 621, 622, 623, a tray slider 624, a belt conveyor 625, and a tray slider 626.

  As shown in FIG. 3A, the troughs 621 to 623 are substantially the same substantially plate-like members having a long shape and using stainless steel or the like. As shown in FIG.3 (b), the cross section substantially perpendicular | vertical to the longitudinal direction of these troughs 621-623 has a substantially V-shaped shape. These troughs 621 to 623 are formed by pressing one substantially plate-like member into a substantially V shape (trough shape) or welding a plurality of substantially plate-like members into a substantially V shape. .

The troughs 621 to 623 are juxtaposed in the left-right direction (in the width direction) so that the respective longitudinal directions are substantially parallel, and are connected along the longitudinal direction. At one end in the longitudinal direction of each of the connected troughs 621 to 623, the troughs 621 to 623 are connected to a raw material input port 627 from which the dry solid 130 is input from the circular feeder 61. The troughs 621 to 623 are arranged in a substantially aligned state at the other end with respect to the one end, that is, at the end portion 628 on the side where the dry solid material 130 is introduced into the automatic packaging machine 1.
Hereinafter, the end portion 628 on the side where the dry solid 130 is charged is referred to as a charging side end portion 628. The end 629 on the side to which the dry solid 130 is supplied from the circular feeder 61 with respect to the charging side end 628 is referred to as a supplied side end 629. Further, since the dry solid 130 is supplied from the supply-side end 629 side and supplied from the input-side end 628 to the filling chute 7, the input-side end 628 and the supply-side end 629 are dry solids. The front end portion and the rear end portion are based on the 130 transfer direction.

  In FIG. 3A, the troughs 621 to 623 are connected along the length thereof, but may not be connected. Since the dried solid material 130 is charged in a lump state to the raw material input port 627, the troughs 621 to 623 are connected in the vicinity of the connection portion with the raw material input port 627 in order to receive the dried solid material 130 that has become a lump. It is preferable.

  In the troughs 621 to 623, cut portions 631 and 632, cut portions 633 and 634, and cut portions 635 and 636 are formed. These cut portions 631 to 636 are formed in the middle of the supplied side end portion 629 and the input side end portion 628. More specifically, the cut portions 631 to 636 are formed in the middle portions of the lengths of the troughs 621 to 623, and are formed at substantially the same locations in the respective troughs 621 to 623.

  The cut portions 631 and 632 of the trough 621 are formed by cutting into both slopes 641 and 642 having a substantially V-shaped cross section from these upper ends to a predetermined depth. These cut portions 631 and 632 are cut from the upper ends of the slopes 641 and 642 so that a height of about one dry solid 130 remains from the upper ends of the slopes 641 and 642. The cut portions 633 to 636 of the troughs 622 and 623 are formed on the inclined surfaces 643 to 646, similarly to the trough 621. In addition, the cut portions 631 to 636 have substantially the same substantially rectangular shape, but can have various other shapes. Such cut portions 631 to 636 allow one dry solid 130 to pass near the bottom of the troughs 621 to 623 in the vicinity thereof.

  As shown in FIG.3 (b), the cross-sectional shape substantially perpendicular | vertical to the longitudinal direction of the troughs 621-623 is substantially V shape. Further, a support member 630 that supports the troughs 621 to 623 is joined to the bottom side of the troughs 621 to 623. The support member 630 is a substantially plate-like member, and the bottom surfaces of the troughs 621 to 623 are fixed on substantially the same plane by the support member 630. The slope 642 of the trough 621 and the slope 643 of the trough 622 are connected to the slope 644 of the trough 622 and the slope 645 of the trough 623 at their upper ends.

  Further, the support member 630 that supports the troughs 621 to 623 is connected to a vibration device, an elastic member, a mounting base, and the like, although not shown in FIG. The support member 630 is swingably supported by the automatic packaging machine 1 by these members. At the same time, the support member 630 is provided with vibrations in the front-rear direction (left-right direction in FIG. 3C) from these members, and the troughs 621 to 623 can swing up and down by this vibration. More specifically, when the supply-side end 629 of the troughs 621 to 623 swings up and down, the charging-side end 628 located on the opposite side moves up and down in the opposite direction, and the troughs 621 to 623 swing back and forth. Can do.

  As shown in FIG. 3C, the supply-side end 629 connected to the raw material input port 627 is lower than the input-side end 628 that is the front end of the troughs 621 to 623 facing the opposite side. ing. In other words, the troughs 621 to 623 and the raw material inlet 627 are arranged such that the dry solid 130 moves from the low supply side end 629 to the high input side end 628. That is, the troughs 621 to 623 are inclined such that the right side in FIG. 3 is higher than the left side. Further, as shown in FIG. 3C, a cut portion 631 of the trough 621 is formed on the slope 641.

  As shown in FIG. 3A, the tray slider 624 is a substantially rectangular tray when viewed from above, and an open end 651 is formed by removing one side surface (wall surface) thereof. As shown in FIG. 3B, the tray slider 624 is disposed below the troughs 621 to 623. The tray slider 624 has such a size that all of the cut portions 631 to 636 can be disposed on the tray slider 624 in this arrangement state. More specifically, the tray slider 624 has a long side longer than the length of the troughs 621 to 623 in the short direction, and a short side longer than the length of the cut portions 631 to 636 along the length of the troughs 621 to 623. Has a substantially rectangular shape when viewed from above.

  As shown in FIGS. 3B and 3C, the tray slider 624 is inclined so that the belt conveyor 625 side is lowered. That is, the tray slider 624 has an inclination such that the open end 651 side is lowered. Further, the tray slider 624 is arranged so that the vicinity of the open end 651 reaches the belt conveyor 625. The vicinity of the open end 651 of the tray slider 624 is disposed on the belt conveyor 625 in a state of being separated from the surface of the belt conveyor 625.

  The belt conveyor 625 is a long conveying means, and conveys the dry solid 130 by moving the surface thereof in a predetermined direction. As shown in FIG. 3A, a tray slider 624 is disposed near one end in the longitudinal direction of the belt conveyor 625. The other end of the tray slider 624 side end is disposed on the tray slider 626. More specifically, as shown in FIG. 3C, the belt conveyor 625 is inclined so that the tray slider 624 side is lower than the tray slider 626 side.

As shown in FIG. 3A, the tray slider 626 is a substantially rectangular tray in a top view, like the tray slider 624, and one side surface (wall surface) is removed from the open end portion 652. The tray slider 626 is disposed below the belt conveyor 625 as shown in FIG. At the same time, the vicinity of the open end 652 of the tray slider 626 is disposed on the raw material inlet 627.
As shown in FIG. 3B, the tray slider 626 is inclined such that the belt conveyor 625 side is higher than the raw material inlet 627 side. That is, the tray slider 626 has an inclination such that the open end 652 side is lowered.

Next, the charging of the dry solid 130 by the linear feeder 62 will be described in detail with reference to FIG. FIG. 4 shows a state of the linear feeder 62 during operation, FIG. 4A shows a top view observed from above during operation, and FIG. 4B shows a perspective view of the troughs 621 to 623 during operation. Has been.
The dry solid 130 is fed from the raw material hopper 60 of the raw material supply device 6 to the linear feeder 62 via the circular feeder 61. As shown in FIG. 4A, the linear feeder 62 receives the dried solid 130 near the raw material inlet 627. At this time, as shown in FIG. 4B, the dry solid 130 is dropped and received from the circular feeder 61 in a lump state.

  The troughs 621 to 623 and the raw material inlet 627 of the linear feeder 62 receive vibration in the front-rear direction from a vibration device or the like (not shown) connected to the support member 630. This vibration is transmitted to the dry solid 130 formed as a lump on the troughs 621 to 623 and the raw material inlet 627. The mass of the dry solid 130 to which the vibration is transmitted gradually collapses between the slopes 641 to 644 of the troughs 621 to 623. When the troughs 621 to 623 and the raw material inlet 627 are shaken back and forth, the broken dry solid 130 is gradually transferred along the troughs 621 to 623. At this time, the broken dry solids 130 are arranged in a line near the bottom of the troughs 621 to 623 having a substantially V-shaped cross section, or overlap the dry solids 130 arranged in this line.

  When the dry solid 130 is transferred, it passes through the middle part of the troughs 621 to 623. Cut portions 631 to 636 are formed in the middle of the troughs 621 to 623. In these cut portions 631 to 636, one dry solid 130 can pass through, so as shown in FIGS. 4 (a) and 4 (b), the vibration transmitted to the linear feeder 62 causes the most. The dry solid 130 that has overlapped on the dry solid 130 below is discharged from the cut portions 631 to 636 to the outside of the troughs 621 to 623 and screened down below the troughs 621 to 623.

  When the overlapped dry solids 130 are screened at the cut portions 631 to 636, all the dry solids 130 on the troughs 621 to 623 are aligned (see FIG. 4A). The dry solid 130 is transferred to the input side end 628 in this one-row state. At this time, since the troughs 621 to 623 have a charging side end 628 to the filling chute 7 higher than the supplied side end 629 of the raw material charging port 627, the acceleration of the dry solid 130 ahead of the transfer direction is increased. It gradually becomes smaller and its moving speed becomes slower. Therefore, the rear dry solid 130 moves at a faster speed than the front dry solid 130 and catches up with the front dry solid 130, so that the interval between the dry solids 130 is reduced. As a result, the dry solids 130 in a single row are finally transported in a clogged state and put into the filling chute 7 at a relatively slow moving speed.

  Further, the dry solid 130 shaken off at the cut portions 631 to 636 is received by the tray slider 624. The dried solid matter 130 received by the saucer slider 624 slides down on the belt conveyor 625 due to the inclination of the saucer slider 624, and the belt conveyor 625 conveys the fallen dried solid matter 130 to the upper saucer slider 626. The dried solid material 130 carried by the belt conveyor 625 is dropped on the tray slider 626 and received by the tray slider 626. Thereafter, the received dry solid 130 slides down to the raw material inlet 627 due to the inclination of the tray slider 626 and is sent to the troughs 621 to 623 again.

  As described above, in the raw material supply device 6 of the automatic packaging machine according to the present embodiment, the cut portions 631 to 636 are formed in the middle portions of the troughs 621 to 623 of the linear feeder 62. Therefore, at the time of transfer, among the dry solids 130 that overlap each other, the dry solids 130 that overlap with each other can be dropped from the cut portions 631 to 636. Thereby, only the dry solids 130 arranged in a row near the bottom of the troughs 621 to 623 can be left. Therefore, the amount of each of the dry solids 130 falling on the filling chute 7 can be adjusted by dropping each of the dry solids 130 arranged in a row from the troughs 621 to 623 onto the filling chute 7. .

  Furthermore, since the troughs 621 to 623 are inclined so as to increase along the transfer direction of the dry solid 130, the moving speed of the dry solid 130 can be gradually reduced when the trough 621 to 623 is thrown into the filling chute 7. it can. Therefore, the interval between the dry solids 130 in a single row state can be shortened, and when falling onto the filling chute 7, the dry solids 130 can be in a continuous state. As a result, the solids can be arranged substantially uniformly, and the individual dry solids 130 can be introduced at regular intervals.

  Furthermore, since the moving speed of the dry solid 130 at the time of charging into the filling chute 7 can be reduced by the inclination of the troughs 621 to 623, the dry solid 130 that falls into the charging chute 7 and is charged easily Can be controlled. As a result, it is possible to easily adjust the amount of the dry solid 130. Therefore, the amount of the dry solid 130 can be adjusted, and furthermore, the amount of the dry solid 130 can be adjusted to a constant amount because it can be charged almost uniformly.

  Further, the dried solid material 130 dropped from the troughs 621 to 623 is received by the tray slider 624 and then fed to the raw material inlet 627 by the belt conveyor 625 and the tray slider 626. Therefore, since the fallen dry solid 130 can be used as the dry solid 130 that is automatically charged again into the filling chute 7, the dry solid 130 can be efficiently thrown into the filling chute 7 without waste.

Embodiment 2 of the Invention
In the second embodiment of the invention, a linear feeder 62 in which a plurality of troughs are vertically arranged will be described. The schematic diagram of FIG. 5 shows another configuration example of the linear feeder 62. In FIG. 5, 661, 662, 663 are troughs in the linear feeder 62 of this other form, 671, 672, 673 are the notches of the troughs 661-663, and 681, 682, 683 are the raw material inlets. It is. In the present embodiment, the same members as those in the first embodiment of the invention are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 5A, the troughs 661 to 663 are arranged in three rows in a state of being separated in the vertical direction. The cut portion 671 of the trough 661 is disposed on the raw material inlet 682 of the trough 662 in this juxtaposed state. Similarly, the cut portion 672 of the trough 662 is disposed on the raw material inlet 683 of the trough 663. A tray slider 624 is provided below the cut portion 673 of the trough 663 disposed at the lowermost portion.

  In these troughs 661 to 663 arranged above and below, the dried solid matter 130 dropped from the cut portion 671 of the uppermost trough 661 is received by the trough 662. The dried solid matter 130 that has been screened off from the cut portions 672 and 673 of the troughs 662 and 663 is received by the trough 663 and the tray slider 624 in this order. Although not shown in FIG. 5, the dried solid material 130 that has fallen on the tray slider 624 is again loaded into the raw material inlet 691 of the uppermost trough 661 by the belt conveyor 625 and the tray slider 626.

  As shown in FIG. 5B, a new trough 664 may be provided in place of the bottom tray slider 624. In this case, by adjusting the total amount of the dry solid 130 supplied to the uppermost trough 661, it is possible to arrange the dry solids 130 finally dropped on the lowermost trough 664 in a line.

  The troughs 661 to 664 are long members having a substantially V-shaped cross section, similar to the troughs 621 to 623. The shapes of these troughs 661 to 664 may be substantially the same, but the shape in which the slopes of the troughs are opened wider in order downward (in the order of troughs 661, 662,...). It can be. Thereby, the lower trough can reliably receive the dry solid material 130 falling from the upper trough.

  In addition, the troughs 661 to 664 are inclined back and forth to approximately the same degree (front and rear with respect to the transfer direction), but may be inclined to different degrees. For example, in the troughs 661 to 664 in which the amount of the dry solid 130 is small, there may be a case where the space between the dry solids 130 in a line is opened. In this case, by increasing the inclination of the troughs 661 to 664, the acceleration of the dry solid 130 when it is put into the filling chute 7 may be greatly reduced. More specifically, when the amount of dry solid 130 falling on the trough 664 is small, the interval between the dry solids 130 can be more reliably reduced by increasing the inclination of the trough 664.

Thus, by arranging the troughs 661 to 664 in the vertical direction, it is possible to control the dry solid material 130 to be charged for each of the troughs 661 to 664. Thereby, the amount adjustment of the dry solid 130 can be made simpler.
Further, when the trough 664 is provided at the lowermost part, the dry solid 130 can be supplied to the filling chute 7 while adjusting the amount thereof without providing the tray slider 624, the belt conveyor 625, and the tray slider 626. Thereby, the number of parts of the raw material supply device 6 can be reduced, and the production cost of the raw material supply device 6 can be reduced.

In the present embodiment, the straight feeder 62 is provided with three troughs 621 to 623 and four troughs 661 to 664. However, the number is not limited to this, and the number of dry solids 130 to be charged into the filling chute 7 is not limited. One or a plurality of troughs may be provided according to the moving speed of the dry solid 130 or the like.
Furthermore, in this embodiment, the raw material hopper 60 of the raw material supply apparatus 6 supplies the dry solid 130 to the linear feeder 62 via the circular feeder 61, but directly from the linear feeder 62 without using the circular feeder 61. You may make it supply.
In addition, in the raw material supply apparatus of the automatic packaging machine according to the present invention, the trough is provided with a lid, a long trough is formed in a curved shape, or the trough bottom surface and the side surface are connected non-linearly. You can also do it.
