2. Description of the Related Art When cultivating vegetables and flowers in a tunnel or an agricultural house, various agricultural soft films such as soft vinyl chloride film and polyolefin film (hereinafter simply referred to as a film) are used in the tunnel or the agricultural house. There is. There are many kinds of these films having various standards such as width, thickness and length. Films for tunnel cultivation are classified as vinyl chloride.

The used film is collected and sent to a waste plastic reprocessing plant or stored by individual farmers for reuse in the next season. When sending used films to a reprocessing plant, there are standards for packing and packaging, and packaging is also specified. They differ depending on the type of film, but in the case of vinyl chloride, it is required to have a zigzag shape as shown in FIG. Even if it is folded and folded, be sure to attach a registration number to the package, package the vinyl for agriculture and the polyolefin for agriculture separately and package, fluorine-based, hard film,
We do not accept vinyl containing thread, do not mix stones, metal, wood chips, etc. as the cutter will be damaged (please wipe the sand), take measures to prevent sunburn and deterioration of the film (accept severe deterioration) No), and so on.

Regarding the packing form, the cutting conveyor is small, so please pack it in a small size. Further, in the case of vinyl chloride, it is specified that the two parts should be folded and then tied with a string made of the same material as the covering material removed from the house. Moreover, the size of the zigzag folded film B is set to have a width W80 cm, a width L50 cm between the strings, a height H10 to 15 cm, and a weight 15 kg as shown in FIG.

After unfastening, the operator C folds the film B in the standard shown in FIG. 7 as shown in FIG.
Two parts of the film were tied with a string D. When collecting used film and storing it for reuse, it is not necessary to conform to the above standards, but it is easy to store because it is easy to store, so it is folded. .

[0006]

The conventional collecting and folding methods have the following problems. 1. It takes a lot of force to pull the film out of the field, it is hard work, and it is too heavy for children and the elderly. 2. It takes a lot of labor and time to fold the drawn film so that it conforms to the standard, pack it, and pack it. 3. Even if it is packed and packed according to the standard, it is not shipped to the waste plastic reprocessing plant free of charge, and a fixed fee is collected every year as a vegetable shipping association.
For each shipment, charges will be added individually by weight.
4. As mentioned above, since the farmers are burdened with a great deal of labor and money, illegal activities such as illegal dumping and burning in the middle of the night, which are prohibited for environmental protection, frequently occur. There is. 5. Due to the above-mentioned various problems, there is an urgent need for a recovery folding machine and method that can reduce labor and facilitate shipping.

BEST MODE FOR CARRYING OUT THE INVENTION An example of an apparatus for collecting and folding agricultural films according to the present invention is shown in FIGS. 1 and 2, and an example of the apparatus is shown in FIGS. This device is frame 1
A table 11 is formed at 0, and on the entrance side of the table 11, a width alignment guide 5 for uniformly aligning the width of the film is provided. The guide 5 is composed of four vertical guide rollers 12 vertically installed on a table 11. The lateral spacing of the vertical guide rollers 12 is equal to or slightly smaller than the lateral width of the film 2 to be packed, and when the film 2 passes between the two vertical guide rollers 12,
The width of the film 2 is made to match that width. When each of the vertical guide rollers 12 is made rotatable, the film 2 can be smoothly drawn in, but it is possible not to rotate the film. The distance between the vertical guide rollers 12 arranged side by side may be adjustable. By adjusting this distance, the width of the film 2 drawn into the drawing mechanism 1 can be adjusted. Various mechanisms for adjusting the space between the vertical guide rollers 12 can be considered. For example, a horizontally elongated hole is opened in the table 11, and the lower end of the vertical guide roller 12 is inserted into the table 11 and fixed with a nut.
2 is slid in the longitudinal direction of the horizontally elongated hole so that the distance between the vertically arranged vertical guide rollers 12 can be adjusted, or a plurality of insertion holes are opened in the lateral direction of the table 11 at intervals. By inserting the lower end of the vertical guide roller 12 into it and replacing the vertical guide roller 12 with another insertion hole, it is possible to form a mechanism or the like that can adjust the distance between the vertically arranged vertical guide rollers 12. it can.

Two horizontal guide rollers 13 and 14 are rotatably mounted on the table 11. The lateral guide rollers 13 and 14 are provided for facilitating the film 2 passing between the vertical guide rollers 12 to slide on the film 2 to move forward and to be easily drawn into the drawing mechanism 1.

A retraction mechanism 1 is provided above the table 11 near the exit. The width of the retracting mechanism 1 is adjusted by the vertical guide roller 12, and the horizontal guide roller 13
It is for forcibly pulling in the film 2 that is pulled on the top 14. The retracting mechanism 1 includes two rotating rollers 7 and 8
Is mounted on the table 11 in a laterally opposed manner, and a drive gear 16 is mounted on one end of the lower rotary roller 7 in the axial direction. Further, a power chain 17 is hung between the drive gear 16 and a power source 6 such as a motor or an engine, and driven gears 18 and 19 are attached to the other axial ends of both the rotating rollers 7 and 8.
These driven gears 18 and 19 and two tensioning gears 20 rotatably attached to the frame 10 are configured to be driven by a driven chain 21. With the pull-in mechanism 1 having this configuration, when the power chain 17 is rotated by the power source 6, the drive gear 16 rotates, and the rotation of the lower rotating roller 7 causes the driven gears 18 and 19 to rotate. It rotates so that the upper and lower rotating rollers 7 and 8 rotate together. When the upper and lower rotating rollers 7 and 8 rotate, the film 2 is drawn between the rotating rollers 7 and 8 and is fed out as shown in FIG.

A guide mechanism 3 is provided below the front ends of the rotating rollers 7 and 8. The guide mechanism 3 includes both rotating rollers 7,
The film 2 sent out from the film 8 is automatically folded into a zigzag shape. The guide mechanism 3 has a main gear 22 rotatably attached to the frame 10 and a link gear 23 of the lower rotating roller 7 to which a drive chain 24 is applied, and a main gear 22 and a secondary gear rotatably attached to the frame 10. An interlocking chain 26 is hung between the crank 25 and the crank 25, the crank 9 is attached to the rotary shaft of the secondary gear 25, and the support 27 is attached to the tip of the crank 9. The support 27 has a roller 29 rotatably attached to the tip of a receiving member 28 such as a net or a plate. When a stainless material is used for the receiving material 28, the film 2 slides well, the film 2 slides down smoothly without being caught by the receiving material 28, and is smoothly folded into a folded shape.

By configuring the guide mechanism 3 as described above,
When the power chain 17 rotates and the main gear 22 rotates, the sub gear 25 rotates, the crank 9 rotates as the sub gear 25 rotates, and the rotation causes the support 27 to move up and down periodically. It swings (moves up and down). Support 27
4 swings forward (upward) as shown by the phantom line in FIG. 4, the film 2 that is sent out between the rotating rollers 7 and 8 and hangs downward is pushed upwards upward, and the support 27
As shown by the solid line in FIG. 4, when the head is swung downward (downward), the pushing up of the film 2 is released, and the film 2 returns to the front and hangs down. When the support body 27 swings (raises) further upward as shown by the phantom line in FIG. 4, the film 2 is pushed upward and upward. When the swinging of the support 27 up and down is repeated in this manner, the film 2 is sequentially folded into a V shape and automatically folded into a zigzag shape. When the receiving material 28 of the support 27 is a net, the film 2 is supported by the support 27 and pushed up, so that dust, sand, pebbles, etc. adhering to the film 2 fall from the stitches of the receiving material 28. Then removed.

Although the power source 6 such as a motor and an engine is fixed to the frame 10 as shown in the figure, the power source 6 may be detachable from the frame 10. When the power source 6 is removed, the weight of the device is reduced, so that the device can be easily loaded and unloaded. Also, it becomes easy to move when changing the installation location in the field. Although the power source 6 is used to drive the retracting mechanism 1 and the guiding mechanism 3 in the present invention, it is also possible to drive them manually. In that case, it becomes easier to drive by using a foot-operated type like a sewing machine or a foot-operated type like a bicycle pedal.

The outer periphery of the frame 10 is surrounded by a peripheral wall so that the film 2 does not enter the frame 10 from the side so as not to be entangled with a gear or a chain, but in some cases, the peripheral wall may not be enclosed. Wheels 30 are attached to the bottom of the frame 10 to facilitate movement of the device. Also,
A handle 31 is attached to facilitate movement of the device.
Although four wheels 30 are attached in the illustrated one, the number of wheels 30 may be two. In that case, if the wheel 30 is attached to the central portion of the frame 10 in the front-rear direction or slightly ahead thereof, it becomes easy to move while holding the handle 31. In this case, the front side of the frame 10 (handle side)
In this case, one rod-shaped or pipe-shaped support leg protruding downward is provided in advance, and when the hand is released from the handle 31 and the lower end of the support leg is lowered to the ground, the front side of the frame 10 is supported by the support leg. The frame 10 will be stable. When the ground is a field, the lower ends of the support legs bite into the field soil, further stabilizing the ground. The handle 31 can be retractable. Various storage mechanisms are possible. For example, there may be a folding method in which the front side of the handle 31 can be folded downward from the middle in the longitudinal direction, or a slide type in which the front side of the handle 31 can be pushed in and pulled out from the base side of the handle 31. it can.

A collection container 4 can be installed below the outside of the retracting mechanism 1 as shown in FIGS. The recovery container 4 is for accommodating the film 2 which is continuously folded in a V shape by the guide mechanism 3 and folded in a zigzag shape until it falls and is tied with a string 38. The illustrated recovery container 4 is a horizontally elongated box having an upper opening and front and rear walls 35, 3 thereof.
A groove 37 is formed at 6. This groove 37 is for arranging the string 38, and after arranging the string 38 in the groove 37, the film 2 which is formed into a zigzag shape and is continuously bent in a V shape is collected. It is intended to be dropped and stored. In this case, when the film 2 is not sufficiently folded, the film 2 folded in a V shape is collected.
It hits the inner wall surface of the building and is folded in a loop. The film 2 has a predetermined weight (for example,
When it is stored up to 15 kg), cut out the film 2 sent out and replace it with another empty collection container. The film 2 can be bound with the string 38 by lifting the end of the string 38 of the recovery container 4 in which the film 2 is accommodated. The collection container 4 is not a box but may be a box-shaped box made by standing several plates in a square shape, or a box-shaped frame made by standing several bars or pipes at intervals. Good. Other shapes are possible.
