Description

[Detailed Description of the Invention] (a) Industrial Field of Application The present invention involves crushing a compressed package of cardboard boxes, waste paper, etc. in order to facilitate crushing of the package. It is used in the field.

(b) Conventional technology Generally discarded cardboard boxes, waste paper, etc. are compressed to a high density in order to increase the efficiency of transportation to a crushing plant.

For this reason, the highly densely compressed package as described above has been processed as it is in a crusher or the like.

(c) Problems to be solved by the invention However, if a compressed package is processed as is in a crusher, etc., a large amount of driving force is required for the crusher, etc., and the crusher becomes large. There was a problem.

Therefore, there has been a need for an apparatus for crushing the package in advance.

(d) Means for solving the problems The present invention satisfies the above-mentioned needs.
In the package processing apparatus, a package crushing device is provided in front of the pushing device, and the package loaded into the pushing device is pushed forward and the package is crushed by the crushing device, the pushing device A pushing plate is provided in the pit so as to be movable back and forth, a protrusion is provided in front of the pushing plate, and a guide member for guiding the package upward is provided at the front end of the pit at a position that does not obstruct the back and forth movement of the protruding part. The present invention relates to a package processing device in which a rotary drum of the crushing device is provided with a fixed blade for crushing packages guided by a guide member.

(e) Action A compressed package such as a cardboard box is placed in a pit, and the package is moved forward by the protrusion of the pushing plate.As the package moves forward, the package is gradually moved by the guide member. The package, which had been compressed by being pushed upward, moves in a somewhat collapsed state, and the package that has moved forward from the guide member is broken up by the fixed blade of the rotating drum, and the broken state is broken. It can be moved to the next step and processed in the next step easily.

(f) Embodiments The following embodiments will be explained with reference to the drawings.
As shown in the figure, it is comprised of a pushing device 1 for moving the package forward and a crushing device 2 for crushing the package.

The package is made by compressing cardboard boxes and waste paper into a laminated form.

The pushing device 1 is provided with a pushing plate 5 which is moved back and forth by a cylinder 4 in the rear part of the pit 3, and the pushing plate 5 is moved back and forth by a cylinder 4.
A comb-shaped protrusion 6 is provided on the front surface of the pit 3, and the package 7 in the pit 3 is directly pushed by the protrusion 6.

A guide member 8 having a right triangular cross section is provided at the front end of the pit 3, and is adapted to gradually push up the advancing package 7 diagonally forward. Further, a plurality of the guide members 8 are fixed at spaced positions so as not to obstruct the forward and backward movement of the protrusions 6 of the pushing plate 5, and the protrusions 6 can fit between each guide member 8. It's becoming like that.

The crushing device 2 is provided with a rotating drum 9 in front of the pit 3, and the rotating drum 9 is placed horizontally so that its outer circumferential surface faces the pit 3 side. It is designed to be rotated in the direction of the arrow.

12... is a fixed blade for catching and crushing the front surface of the package 7 that has moved forward from the pit 3. The fixed blade 12... is fixed to the outer peripheral surface of the rotating drum 9, and as a whole, Packing body 7 in an inclined shape
It is now easier to crush.

Further, the fixed blades 12 are arranged so as to hook onto the lower part of the package 7 guided by the guide members 8.

13 is a cover that covers the rotating drum 9.

14 is a chute for guiding the crushed package 7.

15 is a conveyor for transporting the crushed packages 7 to the next process.

The present invention has the structure as described above, and its operation will be explained next. First, the package 7 is put into the pit 3.
At this time, the packages 7 are placed so that the stacked state is located in the longitudinal direction of the pit 3.

Thereafter, the cylinder 4 is extended and the package 7 is moved forward by the projections 6 of the pushing plate 5. When the package 7 moves forward, the package 7 is gradually pushed upward by the guide members 8, and the stacked state of the package 7 collapses somewhat.

When the package 7 is moved further forward in a somewhat collapsed state, the fixed blades 12 pull the front surface of the package 7 because the rotary drum 9 of the crushing device 2 is rotating in the direction of the arrow in FIG. The stacked packages 7 are crushed by hanging.

At this time, the protrusions 6 of the pushing plate 5 can move forward between the guide members 8, so the package 7 can be pushed all the way to the rotating drum 9 side. The crushed package 7 is led to a conveyor 15 through a chute 14, and is transferred to the next process by this conveyor 15.

In the embodiment, the fixed blade is arranged to be inclined in only one direction, but the arrangement is not limited to inclination in only one direction, and the same effect can be obtained even if inclinations in multiple directions are combined. It is.

Further, even if the rotating drum is rotated clockwise in FIG. 1, the same effect can be obtained.

(g) Effects of the Invention As described above, the present invention breaks down a package solidified in a layered manner using a guide member, and further breaks the package that has been broken down by the guide member using a fixed blade of a rotating drum. In this way, the packages can be continuously and reliably crushed. Furthermore, since the crushed product can be transferred to the next process, the next process, such as processing using a crusher, can be easily carried out with little effort.
