Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is applicable to polysheets, PVC sheets,
The present invention relates to a compression volume reduction device suitable for compressing and packaging miscellaneous solid wastes that have resiliency properties such as acetic acid vinyl sheets, rags, and paper, or solid products that have restorability properties such as wool and cotton.

[Conventional technology]

As an apparatus for compressing and reducing the volume (packing) of miscellaneous solid waste (hereinafter referred to as solids) having restorability, for example, there is known a device as disclosed in Japanese Utility Model Publication No. 13202/1983. This compression volume reduction device has a rectangular piston inserted into a cylinder with a rectangular cross-sectional shape so as to be movable in the axial direction, and a wire twist joint mechanism is installed on the upper side of the cylinder, and a wire pushing rod is installed on the lower side. After putting a solid material such as waste paper into the cylinder and compressing it with a piston, the lower wire is moved closer to the upper wire by pushing the wire pusher up into the twist joint mechanism through the guide structure formed on the piston. The wire is wound around a solid object, and the upper wire and lower wire are tied together by the action of the twist joint mechanism.

[Problem that the invention seeks to solve]

However, in the above-mentioned compression volume reduction device, when multiple wire push rods are arranged in one plane to bind solid materials at multiple locations, the multiple binding locations become parallel to each other. It can only prevent springback in the X and Y2 directions, and cannot prevent springback in the Z direction. In addition, in order to prevent springback in the X, Y, and Z directions by intersecting multiple bundles, it is necessary to move multiple wire push rods so that they cross in multiple parallel planes. Not only is this complicated, but the wire is also likely to become loose, making it difficult to implement in practice.

Furthermore, when trying to pack solid objects by compressing them into a cylindrical shape, the wires can only be bound in one place unless the wires cross, making it impossible to sufficiently prevent springback. There is also the problem that it is limited to rectangular parallelepipeds.

[Means for solving problems]

The present invention includes a compression cylinder having a discharge port at one end, an intake port at the other end, and a through hole formed at a position facing each other between the discharge port and the intake port. , an opening/closing means for opening and closing the discharge port of the compression cylinder, and a communication hole that communicates with each other a pair of through holes facing each other at the position of the through hole, and a pressing surface of a binding string inserted into the communication hole. between the pressing piston, which compresses the solids put into the compression cylinder from the intake port toward the opening/closing means in the closed state, and the through holes facing each other; Both ends of the binding string, which is stretched across the compression cylinder and pulled into the compression cylinder as the solid material moves during the compression operation of the solid material by the pressing piston, are inserted through the through hole when the solid material is compressed. This method solves the above conventional problem by including a binding device that is inserted into a communication hole of a pressing piston that is aligned with the position of the through hole and welded together within the communication hole. To provide a compression volume reduction device that has a large volume reduction effect, can improve transportation efficiency and space utilization efficiency, and can also be used for compression packaging of wool, cotton, etc.

[Effect]

To compress and pack a solid material that has resilience, first, a binding string is stretched between the through holes, the discharge port of the compression cylinder is closed with an opening/closing means, and the solid material is put into the compression cylinder and pressed. Actuate the piston to compress the solid material. At this time, the above binding string is
As the solid material moves, it is drawn into the compression cylinder.

When binding the binding string, stop the pressing piston when the communication hole matches the position of the through hole,
Insert the binding device from the communication hole into the communication hole of the pressing piston. At this time, during the compression operation of the solid material, the binding machine inserts both ends of the binding cord drawn into the compression cylinder as the solid material moves into the communication hole of the pressing piston, and ties it within the communication hole. Weld the strings together. The binding string bound to the solid object within the communication hole passes through the slit and comes into close contact with the solid object. Therefore, the solid material is bound by the binding cord in a compressed state.

When the binding of the solids is completed, the binding machine leaves the communication hole of the pressing piston and returns to the position before binding.
Thereafter, the opening/closing means is operated to open the discharge port of the compression cylinder, and the press piston is moved to discharge the solid matter.

Incidentally, the compression cylinder 1 is provided with a pressing piston 10 movable in the axial direction by a drive device (not shown), and an intake port 1b between the discharge port 1a and the intake port 1b of the compression cylinder 1. A pair of through holes 11 are provided in the compression cylinder 1 at mutually opposing positions near the sides. In addition, the above-mentioned pressing piston 1
0 is provided with communication holes 13 at positions corresponding to the pair of through holes 11, and a narrow slit 12 is opened along the communication hole 13 on the pressing surface of the pressing piston 10 that contacts the solid object 16. It is provided. A binding string 1 made of polypropylene synthetic resin or the like is placed near the through hole 11.
Four supply units 15 are provided.

The position of the through hole 11 in the circumferential direction with respect to the compression cylinder 1 must be set so that the tying machine 17 and the supply part 15 of the tying cord 14 do not come into contact with the lid 2 that is opened and closed. In order to simplify the explanation, they are provided in the up, down, left and right directions. In the through hole 11, a binding string 14 is stretched across the compression cylinder 1 between the through holes 11 before the solid material 16 having resilience is introduced into the compression cylinder 1.
A binding machine 17 is attached to bind the solid materials 16. This binding machine 17 has the above-mentioned pressing piston 1
During the compression operation of the solid material 16 by the solid material 16, both ends 14a of the binding string 14 drawn into the compression cylinder 1 as the solid material 16 moves, that is, the through hole 1
The binding strings 14 on the top of the press piston 10 are inserted from the through hole 11 into the communication hole 13 of the pressing piston 10 and welded together within the communication hole 13, and are actuated by a drive device 18.

Moreover, on the inner wall surface 1c of the compression cylinder 1,
As shown in FIG. 3, a guide groove 20 is provided for guiding the binding cord 14 that is drawn into the compression cylinder 1 during compression movement of the solid material 16, and a plurality of circumferential grooves 21 are connected to the guide groove 20. is formed. Furthermore, parallel grooves 22 are formed in parallel with the guide grooves 20 between the respective guide grooves 20 on the inner wall surface 1c.

Note that the guide groove 2 is provided in the blocking portion 3a of the slide gate 3 that constitutes a part of the inner wall surface 1c.
A vertical groove 23 communicating with the parallel groove 22 is formed.

A resistance mechanism 24 that adds resistance to the feeding of the binding cord 14 is provided in the supply path of the binding cord 14 between the supply section 15 of the binding cord 14 and the through hole 11. This resistance mechanism 24 is mainly composed of an air cylinder, restrains the binding string 14 by sandwiching it between the air cylinders, adjusts the amount of feeding of the binding string 14 to the compression cylinder 1, and adjusts the amount of feeding of the binding string 14 to the compression cylinder 1. It is designed to give tension to 14. Note that the supply section 15 is provided with a binding cord 1.
4 is slack, an unwinding mechanism using a spring or the like is provided to unwind it.
may be provided directly on the supply section 15 of the binding cord 14 to apply resistance to the supply section 15 itself to adjust the amount of feeding of the binding cord 14 to the compression cylinder 1.

Further, an opening/closing gate 25 that covers the through hole 11 is slidably provided in the through hole 11, and the through hole 11 is opened and closed by an actuating device 26.

In addition, in FIG. 1, 30 is a gate cover of the slide gate 3, and 31 is a cover of the opening/closing gate 25. And these covers 3
0 and 31 are connected via piping 32 to an exhaust unit 35 having a filter 33 and an exhaust fan 34, so that the inside of the compression cylinder 1 is constantly ventilated.

Next, the operation of the compression volume reduction device of the above embodiment will be explained with reference to FIGS. 6 to 10.

In order to compress and pack the resilient solid material 16, first, the binding string 14 is stretched between the through holes 11, the lid body 2 is opened, and the solid material 16 is packed into the compression cylinder 1 by a conveyor (not shown) or the like. Insert. At this time, in preparation for work, the exhaust fan 34 is operated to start ventilation inside the compression cylinder 1. Further, the slide gate 3 and the opening/closing gate 25 are kept closed.

Next, the lid 2 is closed and the pressing piston 10 is operated to compress the solid material 16. Then, the above binding string 1
4 is guided by the guide groove 20 in the compression cylinder 1 as the solid material 16 moves, and is moved into the compression cylinder 1.
The binding string 14 is then drawn in and sent out from the supply section 15. At this time, the resistance mechanism 24 is activated to apply resistance to the feeding of the binding string 14, and adjust the feeding amount of the binding string 14 so that the binding string 14 does not loosen.

Then, when the solid material 16 is repeatedly compressed and introduced into the compression cylinder 1 and the solid material 16 is sufficiently introduced into the compression cylinder 1, the pressing piston 10 is moved to the binding position, that is, the through hole 11 and the pressing piston 10 are At the same time, the opening/closing gate 25 is opened to allow the pair of mutually opposing through holes 11 to communicate with each other. In addition, since the width of the slit 12 is narrow, there is no possibility that the solid material 16 will pass through the slit 12 and enter the communication hole 13 when the solid material 16 is compressed by the pressing piston 10.

Then, as shown in FIG. 9, the binding device 17 is inserted into the communication hole 13 of the pressing piston 10 from the through hole 11. At this time, during the compression operation of the solid material 16, the binding machine 17 connects both ends 14 of the binding cord 14, which is drawn into the compression cylinder 1 as the solid material 16 moves.
a into the communication hole 13 of the pressing piston 10,
Binding cords 14 are welded together within this communication hole 13. The binding cord 14 bound to the solid object 16 within the communication hole 13 passes through the slit 12 and comes into close contact with the solid object 16. Therefore, the solid material 16 is bound by the binding cord 14 in a compressed state, and no springback occurs in the solid material 16 after compression.
The binding machine 17 welds both ends of the binding cord 14 and simultaneously cuts the welded portion back and forth.
Therefore, the next new binding string 14 will be left in tension inside the compression cylinder 1 with the ends welded together.

When the binding of the solid material 16 is completed, the binding machine 1
7 is separated from the communication hole 13 of the pressing piston 10 and returns to the position before binding, and the opening/closing gate 25 is activated by the actuating device 26.
moves to close the through hole 11. Thereafter, the slide gate 3 is operated by the drive cylinder 4 to open the discharge port 1a of the compression cylinder 1, and the connecting tool 6 is opened.
The solid matter 16 is stored in the storage container 5 connected to the discharge port 1a by moving the pressing piston 10. Thereafter, the pressing piston 10 returns to the position shown in FIG. 6 in order to perform the next compression packing operation, but the binding string 1 whose ends are welded to each other through the communication hole 13
4 is a binding string 14 which is separated from the pressing piston 10 through the slit 12 and is sent out in excess when storing the bound solid material 16 in the storage container 5.
Since the supply section 15 unwinds the wire, the wire is stretched between the through holes 11. In the above embodiment,
Since the binding string 14 is guided through the guide groove 20 and drawn into the compression cylinder 1 along with the movement of the solid object 16, the frictional force between the solid object 16 and the binding string 14 is reduced. Furthermore, since the resistance mechanism 24 applies resistance to the binding cord 14 drawn into the compression cylinder 1 during the compression operation of the solid material 16, the binding cord 14 does not slacken within the compression cylinder 1. Therefore, once the solid material 16 is compressed,
Even if the new solid material 16 is put into the compression cylinder 1 and compressed again, the binding string 14 is not sent into the compression cylinder 1 more than necessary together with the new solid material 16, and the binding of the solid material 16 is loosened. There is no.

In the above description, the packed solid material is directly pushed out by the pressing piston 10, but it may be pushed out during the initial compression operation of the solid material. In this way, there is no need to unwind the binding cord. In addition, it can also be used for packaging not only miscellaneous solid waste but also solid products with resilience such as wool and cotton.

Both ends of a binding string stretched across the compression cylinder between the pressing piston and the through holes facing each other, and pulled into the compression cylinder as the solid material moves during the compression operation of the solid material by the pressing piston. and a tying machine which inserts the through-hole into the communicating hole of the pressing piston aligned with the position of the through-hole and welds them together within the communicating hole when the compression of the solid material is completed. Because there are
A solid material having resilience can be compressed with a high compression force, and the solid material in the compressed state can be bound with a binding string. Therefore, after the solid material is compressed, no spring back occurs in the solid material. Therefore, the volume reduction effect of solids is large, and the transport efficiency and space utilization efficiency can be significantly improved. In addition, since the binding string is welded by the binding machine in the communication hole formed in the pressing piston, as shown in the embodiment shown in the figure, a plurality of binding strings are made to cross each other and solid objects are , Y, Z3 direction springback can be prevented and cylindrical shapes can be packed freely.
It has excellent effects such as
