BACKGROUND OF THE INVENTION
The present invention relates to a volume reduction packaging apparatus that compresses and reduces the volume of waste contained therein and further packs it.
[0002]
[Prior art]
Conventionally, as a device to reduce the volume of corrugated cardboard, plastic bags, paper bags, absorbent cotton, PET bottles and other wastes (hereinafter referred to as “processed objects”), to reduce the storage space and reduce transportation costs, Volume reduction devices are known. In addition, a volume-reducing device that can package a volume-reduced material consisting of a reduced volume of the processed material is also known. A conventional volume reduction packaging apparatus includes a volume reduction chamber into which an object to be processed is placed. The volume reduction packing apparatus is disposed in the volume reduction chamber so as to be movable up and down, and is compressed to reduce the volume of the object to be processed in the volume reduction chamber by being lowered. Has a board. A rope passage groove through which the rope passes is formed on the back side of the volume reducing chamber, and the rope that has passed through the rope passage groove extends to the surface around the lower surface of the volume reducing chamber. Further, the compression plate is formed with an insertion hole through which a pulling rod for pulling out the rope is inserted from the front side toward the back side.
[0003]
In this volume-reduction packaging apparatus, an object to be processed is put into a volume reducing chamber, and when a certain amount of object to be processed has accumulated, the compression plate is lowered to reduce the object to be processed to a volume-reduced object. At this time, the rope reaches the surface side from the back side of the volume reducing chamber through the lower surface. Subsequently, the workpiece is again put into the volume reducing chamber, and when a certain amount of workpiece is accumulated, the compression plate is lowered to reduce the volume of the workpiece, thereby increasing the volume of the volume reducing material. Go. This operation is repeated, and when the volume of the volume-reduced material becomes a considerable amount, the extraction rod is inserted into the insertion hole formed in the compression platen, and the rope is hooked on the tip of the extraction rod and pulled out as it is. Then, the rope passes over the reduced volume and is pulled out to the surface. By binding the end of the rope pulled out from the upper surface side of the volume-reducing material and the end of the rope extending from the bottom to the surface of the volume-reducing material, the volume-reducing material can be packed. is there.
[0004]
[Problems to be solved by the invention]
However, in the volume reduction packaging apparatus, the rope simply passes through the rope passage groove formed on the back side of the volume reduction chamber. For this reason, when the rope passes through the rope passage groove, the width between the rope and the rope passage groove is not particularly restricted and may be greatly separated or very close. Here, when the rope and the rope passage groove are separated to some extent, the rope can be easily hooked with the pulling rod. However, when the distance between the rope passage grooves is short, there is a case where the draw rod cannot enter between the rope and the rope passage groove and the rope cannot be pulled out reliably.
[0005]
Further, even if the rope and the rope passage groove are separated to some extent, if the pull-out rod cannot be inserted straight into the insertion hole formed in the compression plate, the rope is pushed in by the pull-out rod. For this reason, the rope could not be pulled out.
[0006]
Accordingly, an object of the present invention is to facilitate the work of packing an object to be processed so that when the object to be processed is reduced in volume and packed, the rope can be reliably pulled out with a pull-out rod. Is to make it.

[0018]
The operation procedure of the volume reduction packaging apparatus having the above configuration will be described.
In the volume reduction packaging apparatus 1, an object to be processed is put into the volume reduction chamber 3, and the object to be processed is reduced in volume and packed, and provided in the compression platen 4 as a previous stage of the volume reduction packing operation. The rope R is passed through the rope guides 34, 34, 34. At this time, the compression platen 4 is moved upward as indicated by a virtual line in FIG. The rope R is unwound from the rope bundles B, B, B attached to the rope bundle attachment portion 37, and passes through the rope passage grooves 11A, 11A, 11A and the rope guides 34, 34, 34. . The ropes R, R, and R that have passed through the rope passage grooves 11A, 11A, and 11A pass through the rope passages 15A, 15A, and 15A provided in the bottom plate 15 as they are, and are hooked on hooks provided on the front surface of the frame. Then, the rope R is set. Among the operations of setting the rope R, the operations of passing the ropes R, R, R through the rope guides 34, 34, 34 are performed in the depth of the volume reducing chamber 3, but the object to be processed is still in the volume reducing chamber 3. Is not put in. For this reason, an operator can easily perform the work of entering the volume reducing chamber 3 and passing the ropes R, R, R through the rope guides 34, 34, 34. The ropes R, R, R passed through the rope guides 34, 34, 34 are guided by the rope guides 34, 34, 34, respectively, and are arranged at substantially the center of the rope passage grooves 11A, 11A, 11A.
[0019]
When the work for setting the ropes R, R, R is thus completed, the opening / closing door 16 is closed, the closing door 17 is opened, and the closing port 16A is opened. Then, objects to be processed such as cardboard and plastic bags that are no longer needed are sequentially introduced from the introduction port 16A and accommodated in the volume reducing chamber 3. When a certain amount of objects to be processed are collected, the charging door 17 is closed, and as shown in FIG. 7A, an operation panel (not shown) is operated to lower the cylinder rod 19 and the compression disk 4 of the hydraulic cylinder 18 and accommodate them. The processed object is compressed to reduce the volume. When the volume reduction operation is completed, the cylinder rod 19 and the compression disc 4 are raised as they are. When it is completely raised to the position indicated by the phantom line in FIG. 1, the object to be processed is again input from the input port 16 </ b> A and accommodated in the volume reducing chamber 3. When a certain amount of objects to be processed is collected, the loading door 17 is closed and a volume reduction operation is performed by operating an operation panel (not shown).
[0020]
By the way, when reducing the volume of the object to be processed by the compression platen 4, as shown in FIG. 8 (a), the volume reduction material G is raised in the rope passage groove 11A formed on the back plate 11 by the pressing force of the compression platen 4. I will try. However, in the volume reduction compression apparatus 1 according to the present invention, as shown in FIG. 8B, the rope guide 34 provided on the compression plate 4 enters the rope passage groove 11 </ b> A formed on the back plate 11. It is out. For this reason, the rope guide 34 can suppress the rise of the workpiece to be raised in the rope passage groove 11A.
[0021]
When the volume reduction operation is repeated several times and the volume reduction product G is packed, the compression plate 4 is stopped in a lowered state, and the volume reduction product G is packed. This packing operation will be described. When the opening / closing door 16 is opened and the packing operation is started, first, as shown in FIG. 7B, the tip member 42 of the pull-out bar 40 faces the height direction so that the compression plate 4 is lowered. The extraction rod 40 is inserted into the formed insertion hole 32. At this time, for example, when the worker is right-handed, the extraction rod 40 is inserted from the right side of the guide projection 33 formed in the insertion hole 32 (FIG. 4). The worker inserts the pulling rod 40 into the back as it is. At this time, since the guide protrusion 33 is formed in the insertion hole 32, the pull-out rod 40 can be inserted straight without being inserted obliquely. Further, the guide member 33 supports the tip member 42 facing in the vertical direction so as not to fall down.
[0022]
When the leading end member 42 of the extraction rod 40 directly hits the rope passage groove 11A formed in the back plate 11, the worker stops the insertion of the extraction rod 40. At this time, since the extraction rod 40 is inserted straight along the guide projection 33, it is guided to the edge of the rope passage groove 11A. A rope R is passed through the rope passage groove 11 </ b> A, and this rope is guided to the center by a rope guide 34 provided in the compression platen 4. Further, since the tip member 42 of the pull-out rod 40 is supported in the vertical direction, the pull-out rod 40 passes through the side of the rope R, so that a situation where the rope R is pushed out can be prevented. .
[0023]
When the tip member 42 of the pull-out bar 40 hits the rope passage groove 11A of the back plate 11, the pull-out bar 40 is rotated approximately 90 degrees counterclockwise as shown in FIG. Then, as shown in FIG. 5, the tip member 42 turns in the lateral direction and wraps around the back side of the rope R. At this time, the rope R is positioned by the rope guide 34 and the tip member 42 of the pull-out rod 40 is positioned by the guide projection 33, so that the tip member 42 of the pull-out rod 40 is reliably wound around the back side of the rope R. be able to.
[0024]
Thus, when the extraction rod 40 is rotated and the tip member 42 of the extraction rod 40 is turned around the back side of the rope R, the extraction rod 40 is pulled forward. Then, the rope R is pulled out to the front, and when the pulling rod 40 is pulled as it is, the rope R is pulled out to the near side of the compression platen 4 as shown in FIG. Thereafter, the rope R is removed from the compression platen 4. Then, the rope R is cut into an appropriate length, and the end of the rope R fixed to the hook is removed. Then, one end of the cut rope R and the other end of the rope R fixed to the hook are connected and tightened.
[0025]
Thereafter, the extraction rod 40 is inserted from the other insertion holes 32 and 32 and the same operation is performed. The ropes R and R are extracted from the insertion holes 32 and 32, respectively, and the ropes R and R are taken out from the compression platen 4. Then, the ropes R, R are cut into appropriate lengths and tied to the other ends of the ropes R, R fixed to the hooks. Thus, the reduced volume G is packed, and the packed reduced volume G is taken out from the near side.
[0026]
The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. For example, in the above-described embodiment, three rope passage grooves are formed. However, these may be an appropriate number such as two or four. In the above-described embodiment, the guide protrusion is provided in the insertion hole of the compression disc. However, the guide protrusion may not be provided.
Moreover, in the said embodiment, although the rope guide 34 is attached with respect to the compression board 4, a compression board and a rope guide can also be shape | molded integrally. Moreover, in the said embodiment, although the guide protrusion 33 is attached to the insertion hole 32, an insertion hole and the guide protrusion can also be shape | molded integrally.
