FIG. 1 is a longitudinal sectional view of a container cutting and volume reducing apparatus according to an embodiment of the present invention, FIG. 2 is an AA sectional view of FIG. 1, FIG. 3 is a BB sectional view of FIG. 1, FIG. 5 shows the operation of the cutting volume reducing device, and FIG. 6 shows the volume reduction state of the cut drum can.

As shown in FIGS. 1 to 3, a semi-circular metal mold 12 having an opening at the top is integrally formed on a box-shaped frame 11, and a metal mold 12 is formed below the metal mold 12. A rotating roller 13 and a supporting roller 14 which are parallel to each other are rotatably supported, and their outer peripheral surfaces project from the inner peripheral surface of the die 12 through openings. Further, a driven gear 15 is integrally fixed to the rotary roller 13, and the driven gear 15 meshes with a drive gear 17 which is integral with a pulley 16. On the other hand, a drive motor 18 is installed under the pedestal 11, a pulley 19 is fixedly connected to the output shaft of the drive motor 18, and a belt 20 is wound around the pulleys 16 and 19.

Therefore, when the drive motor 18 is driven, the driving force is transmitted to the driven gear 15 via the pulley 19, the belt 20, the pulley 16, and the drive gear 17, and the rotary roller 13 integrated with the driven gear 15 is transmitted. It can be rotated.

A screw shaft 21 is rotatably supported in a lower portion of the gantry 11 along a direction orthogonal to the axial direction of the rotary roller 13 and the support roller 14, and an operation handle 22 is attached to one end of the screw shaft 21. A nut 23 is screwed onto the screw shaft 21. A pair of parallel guide rails 24 are laid on both sides of the screw shaft 21, and a cutting base 26 is movably supported by the guide rails 24 via linear bearings 25. A nut 23 is connected to the lower surface.

A drive motor 27 is mounted on the lower part of the pedestal 26, and a pulley 28 is fixedly connected to its output shaft. On the other hand, a support shaft 31 having two brackets 30 fixed thereto is rotatably supported by a bracket 29 on the upper portion of the frame 26. A pulley 32 is fixedly connected to one end of the support shaft 31, and a belt 33 is wound around the pulleys 28 and 32. An opening 34 is formed in the metal mold 12 facing the cutter 30.

Therefore, when the drive motor 27 is driven, the driving force is transmitted to the support shaft 31 via the pulley 28, the belt 33, and the pulley 32, and the cutter 30 integrated with the support shaft 31 can rotate. It is like this. Further, when the operation handle 22 is rotated, the screw shaft 21 rotates and the nut 23 screwed with the screw shaft 21 moves in the axial direction of the screw shaft 21, and the cutting rack 26 integrated with the screw shaft 21 is provided. That is, the cutter 30 can be moved.

Further, a base end portion of a pressing arm 35 is pivotally supported on an upper portion of the gantry 11, and a supporting roller 36 is rotatably attached to an intermediate portion. Further, a downwardly U-shaped support frame 37 is fixed to the gantry 11, a cylinder 38 is mounted on the upper part of the support frame 37, and a cylinder rod 39 can move downward. A crushing die 40 is fixed to the tip of the crushing die 40. The width of the crushing mold 40 is ⅔ of the axial length of the drum 50 whose volume is cut and reduced, and the mounting position is one side as shown in FIG. A pair of guide bars 41 are attached to the crushing mold 40, and the guide bars 41 are movably supported by a guide cylinder 42 fixed to a support frame 37.

Then, a case will be described in which the cutting and volume-reducing device of this embodiment is used to cut and crush the drum can 50 that has been used and is discarded for volume reduction.

First, as shown in FIG. 1, a drum can 50 having a bottom without a lid is placed in a receiving mold 12, and the lower part of the drum can 50 is rotatably supported by a supporting roller 14 and a rotating roller 13. Then, the pressing arm 35 is lowered, and the supporting roller 36 supports and stabilizes the upper portion of the drum can 50. In this state, the drive motor 18 is driven to rotate the rotating roller 13 to rotate the drum can 50.

Then, the drive motor 27 is driven to rotate the cutter 30, and in this state, the operation handle 22 is operated to rotate the screw shaft 21 to move the pair of cutters 30 supported by the cutting frame 26. Advance to the drum can 50 side. Then, as shown in FIG. 4, the two rotating cutters 30 are brought into contact with the outer peripheral surface of the rotating drum can 50 through the openings 34. Then, the drum can 50 is cut into three parts, that is, the upper part 51, the central part 52, and the bottom part 53. Then, the operation handle 22 is operated in the opposite manner to the backward movement of the cutter 30, and the drive motor 27 is stopped to stop the rotation of the cutter 30. Further, the drive motor 18 is stopped to stop the rotating roller 13 and the rotation of the drum can 50 is also stopped.

Next, as shown in FIG. 5, the holding arm 35 is lifted to release the support of the drum can 50 by the support roller 36. Then, the cylinder 38 is operated and the crushing mold 40 is lowered through the cylinder rod 39 to apply a crushing load only to the upper portion 51 and the central portion 52 of the cut drum can 50 to crush it.

Thereafter, as shown in FIG. 6, the crushed drum can 50 is taken out from the die 12, and the upper portion 51 and the central portion 52 thereof are fitted to each other, and in this state, the drum can is cut and not crushed. By storing the drum can 50 in the bottom portion 53 of the drum 50, the volume of the drum can 50 is reduced.

In this way, the drum can 50 is cut into three parts, that is, the upper part 51, the central part 52, and the bottom part 53, and only the upper part 51 and the central part 52 are crushed and fitted to each other. By storing the drum can 50 in the bottom portion 53, the volume of the drum can 50 is reduced to 1/3.
