BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste packaging material processing apparatus for compressing waste packaging material removed from a package so as not to be bulky.

[0002]

2. Description of the Related Art Generally, about 180 to 300 sheets of can lids which are wound around a can opening in a canning line or a canning production line are wound in a state of being stacked in a cylindrical shape with a packaging material such as recycled paper. The packaging material is supplied to an automatic incision device for the packaging material attached to the device, and the packaging material is incised and removed by the device, and then supplied one by one to the winding device. Conventionally, the waste packaging material removed from the can lid body by the automatic can lid packaging material incision device is a basket for storing the waste packaging material which is arranged to be opened below the device.
It is processed by dropping it into a container such as a box or a bag and storing it, and when the storage container is full, replacing it with the next empty storage container.

However, the waste packaging material that has fallen into the storage container is in a fluffy state while maintaining its original cylindrical shape, and is bulky. In particular, recently, a high-speed line of 2000 cans / minute has appeared, and as a result of frequent cutting and removal of packaging materials, crushing of waste packaging materials must be performed at intervals of 10 to 15 minutes. There was a problem that required personnel for that.

[0004] In order to solve the above problem, the present applicant has
First, a waste packaging material processing apparatus that can automatically compress and drop the waste packaging material removed from the packaged object into the storage container and does not require manual crushing work has been provided (see Japanese Utility Model Application Laid-Open No. Hei 5-5-2).
13906).

[0005]

The waste packaging material processing apparatus described above automatically compresses the waste packaging material, so that the volume of the waste packaging material at the time of being accommodated in the storage container is particularly small as compared with the conventional one. Thus, the predetermined purpose was achieved in that the manual crushing operation was unnecessary. However, the waste packaging material recovers to some extent due to its restoring force when the pressure is released even if it is strongly compressed, so that it becomes bulkier than that when compressed, and it is not possible to reduce the volume to the state when compressed. There is a problem that cannot be done.

The present invention is to improve the previously proposed apparatus so as to solve the above problem, and to obtain a waste packaging material processing apparatus capable of processing waste packaging material more compactly. Accordingly, it is an object of the present invention to provide a waste packaging material processing apparatus which can enhance the compressibility of the waste packaging material and reduce the amount of restoration after the compression processing, thereby further reducing labor. I do.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a waste packaging material processing apparatus according to the present invention is capable of absorbing a water-absorbing waste packaging material supplied from a hopper into a pusher stroke in a compression space having an outlet regulating device. A waste packaging material processing apparatus that performs compression processing by pressing with a pusher device, wherein a spray nozzle that sprays water droplets on the waste packaging material that has reached the compression space is provided above the compression space. ing.

The pusher device includes a first-stage stroke for pushing the waste packaging material to a position below the spray nozzle, and a second-stage stroke for stopping at this position, spraying the waste packaging material with water, and further pressing the waste packaging material to compress it. It is desirable to configure a dual stroke cylinder having a stepped stroke. The outlet restricting device includes an opening / closing lid rotatably provided at a compression space outlet, an actuator for driving the opening / closing lid to open and close, and a lower edge of the opening / closing lid to be locked in a closed state. By comprising a lock member and an actuator for displacing the lock member to two positions of a locked state and a released state, the waste packaging material can be surely compressed by a strong press pressure, and the treated waste packaging material is processed. Can be reliably discharged from the compression space.

[0009]

The pusher reciprocates in a predetermined cycle, and pushes the waste packaging material supplied in the pusher stroke to below the spray nozzle in the first stroke, and temporarily stops. When the waste packaging material reaches below the spray nozzle, the spraying device is operated to spray a predetermined amount of water to the waste packaging material to give a suitable humidity. After that, the pusher presses the waste packaging material against the open / close lid with the second-stage stork and presses.When the waste packaging material reaches a certain amount in the compression space, the actuator operates to open the open / close lid, and the pusher discards the waste from the compression space. Extrude the packaging material. By compressing the waste packaging material after imparting moisture, the compressibility at the time of pressing is improved, and the restoring force after the compression force is released is lost, thereby increasing the pressing effect. The amount of water to be sprayed varies depending on the material and capacity of the waste packaging material, and is adjusted to give optimum moisture.

[0010] By configuring the outlet restricting device as described in claim 3, the opening / closing lid is locked in the closed state to withstand a strong pressing force, and the waste packaging material is compressed with a strong press pressure. After the compression process, the opening / closing lid can be reliably opened, and the treated waste packaging material can be smoothly discharged from the compression space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a waste packaging material processing apparatus according to the present invention will be described below in detail with reference to the drawings. The present embodiment relates to a waste packaging material treating apparatus provided below an automatic can lid packaging material incising apparatus and treating cut empty cylindrical bags cut from the apparatus. In the figure, 1 is a hopper,
The waste packaging material has a depth equal to or greater than the axial length of the waste packaging material so that it can receive the waste packaging material falling from the can lid packaging material automatic cutting device (not shown). The hopper drop port 2 is open in a rectangular cross section. The inclined wall 3 is supported by the air cylinder 4 so as to be tiltable as shown by the imaginary line in FIG. 1, and can be adjusted so that the waste packaging material easily falls. The base plate 6 is separated from the hopper drop port 2 by a predetermined distance.
In the drawing, an upper plate 7 is provided extending from the right end of the hopper drop port 2 to the left along the left side. An upper plate 7 is provided above the extended portion from the lower end of the drop port in parallel with the base plate 6, and is disposed between the hopper drop port 2 and the base plate 6. Compressed space 8 for packaging material
Is formed.

At the right end side of the compression space 8, a pusher device 10 having a pusher 11 which enters and exits the space is arranged. In this embodiment, the pusher device 10 attaches the common pusher 11 to the three cylinders 12 at the tip of the cylinder rod, and the pusher 11 is always in the parallel state even if the packaging bag acts unevenly in the width direction of the pusher 11. , But the number of cylinders is arbitrary. 13 is the cylinder 12 from the upper edge of the pusher.
A safety plate extending over the top surface, having a sufficient area to cover the hopper drop port 2,
With the movement of the pusher 11, the lower end of the hopper falling port 2 is closed to receive the waste packaging material falling from the hopper during the movement of the pusher 11, thereby preventing the waste packaging material from falling between the cylinder rods. As shown in FIG. 1, a goodwill shutter 9 made of a flexible material such as rubber is hung down on the inlet side of the compression space 8. It is designed to prevent a return with a return movement.

The cylinder 12 is a dual-stroke cylinder, which pushes the waste packaging material to the position of the spray nozzle in the first stroke and temporarily stops it, and compresses the waste packaging material in the second stroke, as described later. Has become.

A spray device 15 having a spray nozzle 16 for spraying water droplets on the waste packaging material that has reached the compression space 8 to give an appropriate humidity is provided above the inlet side of the compression space 8.
Are provided in parallel (five in the embodiment shown in FIG. 2). In the spray device 15, the base end portion 18 of the injection pipe 17 is connected to a water supply pipe (not shown), and the amount of water to be jetted can be adjusted by an adjustment nozzle.

An outlet at the left end side of the compression space 8 has a function of pressing the waste packaging material between itself and the pusher 11 and a function of opening the compression space after the pressing to enable discharge of the waste packaging material. A regulating device 20 is provided. The outlet restricting device 20 includes an opening / closing lid 21 rotatably provided at the compression space outlet, and an opening / closing lid having a base end pivotally attached to a shaft 22 and a piston rod tip connected to the opening / closing lid 21. An actuator 23 such as a lid driving cylinder and the like, a lock member 24 which is locked to the lower edge side of the open / close lid 21 to lock the open / close lid in a closed state, and displaces the lock member to two positions of a locked state and a detached state. And an actuator 25 such as a solenoid.

Reference numeral 27 denotes a discharge conveyor for conveying the waste packaging material falling from the outlet of the compression space to the storage container, and reference numeral 28 denotes a discharge guide. In the present embodiment, the compressed waste packaging material is once received by the discharge conveyor 27 and transported to a storage container (not shown). Of course, the storage container is positioned immediately below the compression space outlet. It is also possible to drop the waste packaging material directly into the storage container.

The waste packaging material processing apparatus of this embodiment is configured as described above, and operates as follows. The opening / closing lid 21 is always in a position to close the compression space outlet as shown by a solid line in FIG. 1 and is in a state of being locked by the lock member 24. The cylinder 12 is driven in a predetermined cycle at substantially the same timing as the drop of the waste packaging material, and the waste packaging material dropped onto the base plate 6 from the drop port 2 of the hopper 1 is passed through the pusher 11 at the first stroke. Push down to below spray nozzle 16 to temporarily stop. When the waste packaging material reaches below the spray nozzle, the spray device 15 is operated to spray water on the waste packaging material to give a proper humidity.

After spraying the waste packaging material with water, the cylinder 1
2 operates again to press the waste packaging material against the opening / closing lid 21 in the second stroke to compress it. In the following, the waste packaging material is sequentially compressed by the repetition, but since the waste packaging material is provided with moisture, the compressibility is good and even when the cylinder moves backward, the waste packaging material is restored and spreads or falls into the compression space. Compression can be performed satisfactorily.

When the amount of the waste packaging material deposited under pressure in the compression space reaches a certain amount, the actuator 25 operates to lower the lock member 24 to unlock the open / close lid, and
The actuator 23 is operated to rotate the opening / closing lid 21 to open the outlet of the compression space, and the pusher 11 pushes out the waste packaging material pressurized and deposited in the compression space and drops it onto the discharge conveyor 27.

In the above process, the pusher 11
Even if the waste packaging material drops from the hopper during the reciprocating movement of the hopper, the safety plate 13 that reciprocates with the pusher is provided, so that the waste packaging material does not fall on the cylinder rod and clogging occurs. There is no. Therefore, it is not always necessary to take the timing between the dropping of the waste packaging material and the operation of the pusher, and the control and the device can be simplified.

With the above-described apparatus, the number of compressed sheets of the can lid packaging material made of recycled paper was about 70 sheets / time when water spraying was performed and when water spraying was not performed.
A compression test was performed at a compression time of 7.5 seconds, and the bulk of the waste packaging material discharged after compression was examined.

As a result, when the water volume is compressed after spraying 2 ml / sheet, the bulkiness in the compression direction is reduced to about 3/5 as compared with the case where the water volume is simply compressed without spraying, and the compression effect is remarkable. It was confirmed that. When the amount of spray water is increased to 3 ml / sheet and the amount of spray water is increased, about 1 /
In the case where the compression time was increased to 10.5 seconds with the spray water amount of 3 ml / sheet, the reduction was remarkably reduced to about 2/5. However, when the amount of water spray was further increased, water became excessive and handling of waste packaging materials became difficult.

In the above, the present embodiment has been described with respect to the processing apparatus for the can lid waste packaging material. However, the present invention is not limited to the waste lid packaging material, but may be any water-absorbing packaging material. It goes without saying that the present invention can be applied to a material that compresses and processes various waste packaging materials such as bags.

With a simple configuration, the compressibility of the waste packaging material can be effectively improved, and the amount of restoration after the compression processing is small, and the waste packaging material can be made more compact.
Labor saving for post-processing can be achieved.

Further, according to the configuration of the second aspect, it is possible to surely impart moisture to the waste packaging material, and it is possible to surely and effectively compress the waste packaging material.

Further, according to the third aspect of the present invention, the opening / closing lid can withstand a strong pressing force, and the waste packaging material can be surely compressed with a strong press pressure, and after the compression processing, it can be reliably formed. The open / close lid can be opened, and the treated waste packaging material can be reliably discharged from the compression space.
