Abstract

PURPOSE:To efficiently finish a reed screen product by a method wherein, only with an operation of a worker inserting a screen material into material holding devices, all the following processes are automatically performed. CONSTITUTION:After a material is manually inserted into each material holding device 30 which is attached at the end of each material pulling devices 29, 29' provided on a machine main body 1, the material is pulled into the machine main body by the material pulling devices when a starting button is pressed. When the material is then reached in place, it is forcibly released and pressed down to a specified knotting position by an operation of a press-regulating bar 20 for pressing the material. After that, by a string turning device 36, two strings are, with a half turn, twisted together to the same direction, and the material is knotted. On this operation being ended, the regulating bar 20 is moved upward for restoration and stopped. Each of the material pulling devices is also restored to the original state at the starting position. These operations are repeated and the materials are knotted one after another. In this manner, since the material is knotted with equal tension, an interval between the materials being knotted is finished with the specification, thereby obtaining a beautiful finished product at low cost.

Description

[Detailed description of the invention] A. Industrial application field The only method of manufacturing rectangular bamboo blinds from ancient times using strong fibrous wild plants such as Yoshi, Japanese pampas grass, and bamboo that are distributed throughout Japan as raw materials. We manufacture not only conical, trapezoidal, triangular, circular, etc. bamboo blinds, but also weave patterns to enhance the aesthetic appearance, and use them for day protection, wind protection, frost protection, cold protection, snow damage prevention, etc. Not only is it useful for protecting agricultural and forestry crops, it is also excellent for protecting garden plants in cold, snowy regions, and as a drying underlay for fish, seaweed, wild plants, root vegetables, etc., and is especially suitable for protecting garden plants in cold, snowy regions. It is very easy to put on and take off, and furthermore, with the development of RJJJ's Sudare A manufacturing equipment, it has become possible to make large-sized blinds in various places, and it is expected that they will be offered to the market at low prices, becoming even more versatile, and will also contribute to the revitalization of the village. be.

B. Conventional technology Yoshi and Japanese pampas grass are used as the raw materials for the bamboo blinds.

The string for the material knot is wrapped around a wooden weight multiple times.
A pair of two weights is placed across the crossbar and main, and for each piece of material, the weight in front of the knot is moved to the opposite side, and the weight on the opposite side is moved to the front. Since there are several knots, it is common for people to move from side to side at all times to knit, a primitive domestic craft.

In addition, operating a foot-operated blind knitting machine is hard work, and the machine is long and does not have a mechanical structure that allows it to be carried into the material's own area. However, bent materials cannot be used, and only straight materials can be used, which results in wasted time for selecting materials to be used from the harvested material, and a reduction in the amount of materials used.

C1 Problems to be Solved by the Invention As stated in (A) above, in order to popularize bamboo blinds as socially contributing products, it is necessary to have ■effectiveness, ■low cost, and ■beauty, and these cannot be achieved by conventional methods. In knitting work or on a foot-operated knitting machine, the problem is that it becomes a solid layer.

A major challenge was to solve this problem through automation using electricity.

For the effect of ■, the materials are knotted with uniform tension, and the gaps between the knotted materials are also set to a certain standard to ensure ventilation.

(1) In terms of low cost, the first step is to go electric in order to increase production efficiency, and the second step is to minimize the number of blind manufacturing equipment.
Being able to work close to the natural habitat of the raw materials, 3rd.
In order to get closer to the area where the material grows, the legs of the device are equipped with wheels and skis, making contact with the ground extremely easy and making it possible to change over time, making it easy to transport the equipment year-round. Fourthly, a string ball holder is installed on the top of the machine, and a matching large cylindrical string ball can be used, so frequent replenishment of string is required, as is the case with manual or foot-operated knitting machines. unnecessary.

Fifth, even curved materials can be forcibly pulled into the machine body for knitting.

■In terms of aesthetics, we are not limited to the rectangular bamboo blinds that have been passed down since ancient times, but also various shapes such as one conical, trapezoidal, triangular, circular, etc., as well as one votive knot of material, two or three non-simultaneous knots, composite knots of long and short materials, etc. , In addition, by changing the width and narrowing of the positions between the knots and by making it possible to temporarily rotate or stop some of the string rotation devices, we solved the problem of adding aesthetics by looking at various patternsD. In order to make the machine body as compact as possible, the material pulling device that pulls the material into the main body is a multi-stage tubular stretching and contracting mechanism, and the material gripping device installed at the tip of the material By grasping the material, there is no risk of it falling off during transportation, but when the material is pulled to a predetermined position, it will automatically release and firmly press the material to the knotting position to ensure complete knotting. There is a material presser regulating rod, and a string turning device immediately creates a uniform knot. In addition to the general rectangular shape of the blind, in order to create a deformed blind, among the multiple string ball rests on the main body of the machine, only a specific string ball rest may be temporarily prevented from knotting. There is a solenoid-driven clutch 'gitz. Furthermore, there is a pattern knitting drive device that moves all of the multiple string ball stands on the machine body to the left and right at the same time in a - direction to enable pattern knitting. On the ground, there is a device that allows you to switch wheels to skis very easily.
, Operation and Examples If you manually insert the material into the material gripping device attached to the tip of the material drawing device installed in the machine body and press the start button, the material drawing device will pull the material into the machine body, When the predetermined position is reached, the material is forcibly released, and at the same time, the material presser regulating rod is activated to push the material down to the determined knot site, and immediately after that, the two strings are rotated 180 degrees to each other by the string turning device. Rotate in the same direction to knot the material.

At the same time as the process ends, the material presser regulating rod rises to its original position and stops. The material drawing device is also restored to the starting position. Repeat this process to knit the materials one by one to form a bamboo blind.

In addition, in order to make the machine body as small as possible, the material drawing device is a multi-stage tubular stretching and contracting mechanism. There are two ways to do this: one is to do this by switching high-pressure air, and the other is to use a spring to protrude it and use a drum with a magnetic clutch driven by an electric motor to wind it up and contract it.

Furthermore, the axle and skis provided on the legs of the main body of the machine can be changed over by simply inserting and removing one #I lock bottle.

In addition, multiple string ball stands installed in the main body of the machine are simultaneously rotated 180° equally by a worm screw installed on a single rotating drive shaft to knot the material, which can be used for boat fishing. However, in special cases, when knitting long and short composite bamboo blinds of I material, a solenoid and a This is done by disengaging the mesh using the action of a clutch, etc.

Furthermore, when performing a pattern aIi, after all or part of the string ball stand has been rotated 180 degrees and knotting is performed, the entire string ball YL stand must be rotated in one direction before performing the next turning knot. Pattern knitting is formed by repeating the knotting operation by shifting slightly to the right or left in the longitudinal direction of the machine body. This can be done by a pattern knitting drive shaft.

〔Example〕

FIG. 1 to FIG. 8 show an embodiment of the present device, and (1) in FIG. 1, FIG. 2, and FIG.

All equipment is attached to the main body of the machine.

(2) is a string ball stand, and the string ball (3) is made by wrapping two long strings used for knots into nine cylindrical shapes in a hollow state.
It is meant to store. As you can see in the figure, there are multiple units in the longitudinal direction of the machine body! I will set it up.

As shown in Figure 3, the shaft of the string ball holder (2) is connected to the string 1 mist stand holding bracket (5) by a ball bearing (4).
It is supported by and can rotate freely. Each of the plurality of string ball holder holding fittings (5) can be slid on the machine body in the longitudinal direction, and can also be fixed.

As is clear from FIG. 3, the string ball holder (2) is divided into two parts at the F section, forming a string guide groove fitting (2A). The two cords for the knot branch into two prongs (2A) as shown by dotted lines from the upper arrow, and extend further downward to reach the knot. As shown in the figure, there is a string tension adjuster (6) in the middle, and by tightening or loosening it, the tension of the string at knotting can be adjusted.

(7) is a worm wheel, which is installed on the shaft of the string ball holder (2) so that it can rotate freely, and a part of the worm wheel body has a conical friction clutch receiver (as shown in Fig. 3). 7A) is formed. Also, (8) is a harvested worm wheel that meshes with the worm wheel. Figure 3 (9) is a conical clutch body.
A) indicates a state in which they are engaged so that power can be transmitted.
In addition, the conical clutch body (9) is attached to a string ball stand (
2), and a spline if (I O) is inserted between the shaft and the shaft to engage with each other. Therefore, both can always transmit power [1, and (9) can also slide up and down along the spline of (10).

Next, (11) is a thrust bearing, and as shown in the figure, a presser operating member (12) having a groove on the outer periphery is installed on this bearing.

Also, (13) is a tsurenoid, and (14) is an operating lever, as shown in the figure when there is no current in the solenoid.

Using the force of the operating spring (15), the conical clutch body (9) is moved by the pin at the tip of (14) via (12) and (11).
) is structured to transmit power to the other worm wheel (7) by pressing the solenoid (13) downward.
) When current is applied to (14), it becomes pulled up like (14), and therefore (12), (l l), and (9) each float up due to the spring installed below, and the five-cone clutch The connection becomes loose, and the worm wheel (7) becomes idling independently, making the string ball stand (2) unable to turn at this time.All the string balls placed on the machine body (1) The stand (2) has the above structure.

Next, Fig. 1 (16) is the main drive motor, which is connected to the drive shaft (17), which is the key (18) that extends over the entire length.
) is cut out as shown in FIG. 3, and the worm screw (8) is driven by this key. (19) is the pattern knitting drive shaft, as shown in Figures 1 and 3, the string ball straightening table holding bracket (
It passes through a protrusion (5A) made of the same material as 5). In addition, (19) has a thread cut at the tip as shown in Figure 1, and by rotating this shaft, the entire shaft can slide from side to side in the longitudinal direction. (5)
And the string ball stand (2) slides left and right. This can be done by rotating the pattern knitting drive shaft (19) shown in Figure 1 appropriately after performing the knotting shown in Figure 2 and before performing the first knotting, and by performing the next knotting, the knotted part will be out of alignment with the holder. position. In other words, this allows you to knit your favorite patterns.

Next, the reference numeral (20) shown in FIGS. 1 and 2 is a material holding regulating rod, which is used to plant a large number of materials at arbitrary positions on the regulating rod (2). Both ends of the planting material (21) are made to be able to slide up and down rapidly by motor-driven gears and rack devices and springs, and (22) is a regulating rod rebound spring, (21A) is a sliding member in the guide tube, which is made of the same material as the regulating rod planting material (21), and its lower surface is supported by the regulating rod repulsive spring (22).

(24) is the regulation frame drive motor and the regulation rod drive shaft (25)
is constantly running. A regulating rod drive gear (26) is rotatably installed on this shaft, and this gear is separately attached to ff1.
li! A clutch device can be used to drive or separate from the shaft, and a separate brake device can be used to fix the shaft in a non-rotatable manner.

Furthermore, a regulation frame drive rack (27) is installed in mesh with this gear, and vertically slides up and down as the gear rotates. The lower end of the rack (27) is in pressure contact with the upper surface of the sliding member (21A) in the guide tube via a buffer spring (28). That is, when the rack (27) is lowered, the (2
1A), (21) and the material presser regulating rod (20) compresses the repulsion spring (22) and descends (
20) shows the state in which the tube is lowered to the lowest position and the nodule is held down.

Next, a material drawing device (29 or 29') in FIG. 1 forms a multi-stage tubular stretching and contracting mechanism. FIG. 1 shows this contracted state, and FIGS. 4 and 5 show cross sections in the stretched state, both of which are divided into four parts.

FIG. 4 shows a pressurized air-operated type, and in the same figure (29A) is an extension port, and when pressurized air enters from this port, all the divided parts extend and protrude as shown. On the other hand, if pressurized air enters from (29B), the air will enter into each of the gaps between the double tubes, causing all nine divisions to fully contract.

In Fig. 5, the spring is used, and in order to pull back the spring in Fig. 5 into the contracted state, the spring in Fig.
Connect the wire lobe (29E) tied to the tail of the divided first protruding tube (29D) to the motor-driven pulley (29F).
).

Next, FIGS. 6 to 8 are cross-sectional views of the material gripping device (30) installed at the tip of the first protruding tube (29D). FIG. 6 shows a state where the material is gripped, FIG. 8 shows a state where the material is released, and FIG. 7 is a cross section of the left end surface of FIG. 6 viewed from the front. In these figures, (3OA) is a material gripping spring, which is formed of a plate-like material that acts as a spring, and a plurality of these springs are installed as shown in the figure. (30B) is a material support metal fitting, which is screwed and fixed to the tip of the first protruding tube (29D) of the material drawing device, and is pushed out by an extrusion spring (30C) as shown in FIG. The base of the material forming the blind shown by the dotted line (
30D) between (30A) and (30B), and if you try to pull it out after inserting it, the (3OA
) is gripped more and more tightly and cannot be pulled out. (31) is the material release fitting, and the material pulling device (31)
29 or 29'), but can be freely positioned and fixed inside the machine body.

Figure 1 shows the fully retracted state, Figure 6 shows (30
) and (31) are not in contact with each other, so (30B) is projected by the extrusion spring (30C) and supports (30D). However, as (29D) retreats, (30
) comes into contact with (31), (30C) compresses the spring and becomes the state shown in FIG. In other words, in this state, there is nothing to support the base of the material (30D), and (300)
falls naturally. That is, depending on the set position of the opening fitting (31), the material can be freely dropped to any position on the machine body. In FIG. 1, (30') shows a state in which the material gripping device is stopped at a predetermined position by the opening fitting (31).

Next, as shown in FIGS. 1 and 2, a car N (32) is installed on each leg of the machine body so that it can be moved freely.

Furthermore, the skis (33) are attached to the legs via ski support links (33A) so as to be swingable back and forth, as shown in the figure. However, in order to prevent this swinging and fix it, a fixed bin (
33B) is inserted as shown in the figure.The cage 1 is useful not only for stabilizing the main body of the machine but also for moving on snow. When moving to wheel running, remove one of the fixed bins and the ski will be lifted to the state shown by the dotted line in Figure 1 (33'), allowing the ski to move to axle running. That is, replacing the axle or skis can be done extremely easily by simply inserting and removing a single pin.

The overall structure and embodiments have been described above.

To explain further, the worker first sets the position of the material opening fitting (31) according to the length of the blind to be manufactured. For example, as shown by the dotted line in Figure 1, a material gripping device (30)
Suppose that it comes to the position (30') and contacts the opening fitting (31). At this time, move the worm screw (8) to position (G) to disengage the string ball holder (2) at the leftmost end of the machine so that it does not operate. The root part of the material is manually inserted into the material gripping device (30) at the tip of the material pulling device (29 or 29') which has been protruded and waiting. Next, when the start button is pressed, the material drawing devices (two or 29') are activated and start drawing the material into the machine body.

At the same time, the regulating rod drive motor (24) and the directly connected drive shaft (25) rotate. However, since the driving gear (26) connected to the shaft is released by an electromagnetic clutch installed between the shaft and the shaft, the gear does not rotate and remains stationary. By operating the material pulling device (29 or 29'), the material is pulled into the machine body and the previously set opening fitting (
When (30) hits (31), the material drops, i.e., the state shown in Figure 8 occurs. In response, the electromagnetic clutch of the regulating frame drive gear (26) engages, and the gear (26) immediately begins to rotate at high speed, and at the same time, the clutch (27) that engages with it also rapidly descends 6 Therefore, as is clear from the above, the material is held down. The regulating rod (20) reaches the end point (20') as shown in FIG.
). A signal is transmitted by a microswitch or the like installed here, and the electromagnetic clutch mentioned above disengages the gear (26), but the brake device operates and the gear (26) remains stopped.

That is, the presser foot regulation stop (20) also temporarily stops at this position.

Next, in response to the above-mentioned signal, the string ball holder (2) begins to rotate (180°) and becomes bent. A signal is sent by a micro switch etc. installed here, and the ball rest (2) is temporarily stopped at this point.
It turns out to be twisted. When the gear (26) rotates (180 degrees), the brake device attached to the gear (26) is activated in response to the signal from the microswitch. Due to the fidgeting, the regulating bar rebound (22) rebounds, and the T4 material presser regulating bar (20
) is pushed to the top and stops. (20) receives the signal that it has been pushed up, and the material pulling device (29)
is activated to restore the state of maximum elongation. One cycle ends with this, and by repeating this, blind products (35) are made.
is automatically produced.

Effects of the F1 invention As already detailed, one work tool can hold a material by a material gripping device (30
), all subsequent steps will be performed automatically.
It is possible to efficiently complete blind products, and therefore mass-produced blinds can be offered to the market at low cost.

If both the material drawing devices (29 or 29') installed on the left and right sides of the machine body in FIG. 1 are operated simultaneously, a rectangular bamboo blind product as shown in FIG. 9 can be obtained.

Moreover, by operating only one of the material drawing devices (29 or 29'), using thick and thin knotting strings, and inserting only the base portion of the material, a conical product as shown in FIG. 1O can be obtained.

In addition, when knitting bamboo blinds by mixing long and short materials, the string ball stand (2) should be set at 180° at the part where both the long and short materials are knotted.
Nodulate after each rotation. However, in this case, the knot in the long part of the material, that is, the tip.

- It is necessary to stop knotting from time to time, by activating the solenoid (3) using No. 48 and disengaging the clutch, the rotation of the string ball holder (2) at this point in this part is stopped. This can be achieved by This product can have a deep cone and also has an aesthetic appearance. Figure 11 shows this product, with one short material sandwiched between long materials, but it is of course also possible to sandwich two or three long and short materials. When knitting a pattern, as described above, after one knot is completed, the pattern knitting drive shaft (19) is rotated as appropriate, and then the next knot is performed, and the knot and thread will be misaligned during the same knot. If you do this properly, you will be able to knit patterns in various shapes. This product will have the beauty and dignity of bamboo blinds. FIG. 12 is an example of this.

In addition, although only - pieces of material gripping devices (30) are installed in FIGS. 6 to 8, two pieces are installed at the tip of the material pulling device (29 or 29') in three lateral rows. Then 2, 3
The book material can be drawn into the machine body at the same time, and these two and three
You can tie books together and increase the efficiency of blind weaving. Figure 13 shows a product in which two pieces are knotted together.The products shown in Figures 9 to 13 are just examples of products made using one device, but the devices described above can be used in various combinations. In addition to this, various other unusual products are possible.

G. Other Embodiments (A) The pressurized air actuation mechanism shown in Fig. 4 and the spring repulsion actuation mechanism shown in Fig. 5 regarding the material drawing device can be applied to protruding drawing mechanisms other than the blind a manufacturing device. In particular, in the case of a spring repulsion mechanism, the spring height during compression can be shortened, such as a helical spring.

(O), Figures 6 to 8 show a single-stage material gripping device,
When formed in parallel, it becomes a two-stage material gripping device, and this material,
The n-arm mechanism can also be applied to other devices than this device.

(c), Figures 9 to 13 show examples of products.
The method of combining materials and knitting patterns can be applied to various types.

(d) Regarding the method of pressing the material, please refer to the material presser regulating rod (
20) In addition to the operation method of raising and lowering the material presser, the material presser regulating rod is formed into the required shape and crossed diagonally from both sides.
The intersection moves up and down to press down the material, for example, by using the motor of this device in combination, and by combining, for example, a spring, magnet, weight, belt, etc. with a shaft attached to the end of the material presser regulating rod. You can also do it.

(E) When knitting Sudaku, the string ball stand (
2) does not need to be knotted every 180° rotation; for example, if it is knotted at 360° rotation, the material (30D
) The technical idea of the present invention can be applied in a wide range of combinations, such as increasing the distance between the lines.
