It can be suppressed. As a result, the weight of the transfer device can be reduced.

  According to the third aspect of the present invention, by connecting the pins serving as the rotation center axes of the arms by the shaft, it is possible to easily ensure the positioning accuracy for coaxially arranging the rotation center axes of the arms.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 1, a volume reduction device 1 for waste plastic or the like includes a feed cylinder 2 into which waste plastic is charged, and a rotary that primarily compresses and reduces the waste plastic in the charge cylinder 2 and pushes it into the volume reduction cylinder 3. The press 4, the main press 6 that secondarily compresses and reduces the waste plastic filled in the volume reduction cylinder 3 by the parallel movement of the ram 5, and the bale of the waste plastic that has been secondarily compressed and reduced by the main press 6. 10 is provided with a take-out machine 7 to be taken out from the volume-reducing cylinder 11 and a packing machine 9 to put the bag on the taken-out bale 10 and bind it.

  The bale 10 bound by the packing machine 9 is pushed out onto the roller conveyor 11. The bale 10 has a rectangular parallelepiped shape. After being transferred from the roller conveyor 11 onto the pallet 12, the bale 10 is transferred through the pallet 12 by a forklift.

  The transfer device 20 of the present invention automatically transfers the bale 10 as a transfer object from the roller conveyor 11 to the pallet 12.

  As shown in FIGS. 2 and 3, the transfer device 20 includes a base 21 installed on the floor 8 and a pair of arms 23 and 24 that are supported by the base 21 so as to be rotatable about a horizontal axis. A sandwiching mechanism 30 for sandwiching the bail 10 between the arms 23 and 24, and a pair of hydraulic cylinders 40 as actuators for rotating the arms 23 and 24, with the bail 10 sandwiched between the sandwiching mechanism 30. By rotating the arms 23 and 24 by about 90 °, the bale 10 is automatically transferred from the roller conveyor 11 to the pallet 12.

  The base 21 is formed in a U shape surrounding the roller conveyor 11 on the plan view of FIG. 2, and is installed on the floor 8 without interfering with the roller conveyor 11.

  The rotating front end portions of the arms 23 and 24 are connected via a beam 25, and the portal frame 22 is formed by the arms 23 and 24 and the beam 25.

  A pair of pins 26 and 27 for supporting the base ends of the arms 23 and 24 with respect to the base 21 so as to be rotatable around a horizontal axis are provided. Each pin 26 and 27 is formed at both ends of one shaft 28. The front ends of the pins 26 and 27 are connected to the base 21 via bearings 29.

  The rod-side tip of each hydraulic cylinder 40 is connected to the middle of each arm 23, 24, and the cylinder-side base end is connected to the base 21. As each hydraulic cylinder 40 contracts, each arm 23, 24 is in a position to sandwich the bail 10 on the roller conveyor 11 as shown by the solid line in FIG. On the other hand, when each hydraulic cylinder 40 is extended, each arm 23, 24 is in a position to sandwich the bail 10 on the pallet 12 as shown by a two-dot chain line in FIG.

  The sandwiching mechanism 30 includes a pair of disk-like plates 31 pressed against the bail 10, three pairs of guide rods 32 protruding from the back of each plate 31, and each guide rod 32 inserted through each arm 23, 24 to each plate 31. And a pair of hydraulic cylinders 34 for moving the plates 31 forward and backward with respect to the arms 23 and 24, respectively.

  The rod-side distal end of each hydraulic cylinder 34 is connected to a central guide rod 32, and the cylinder-side proximal end is connected to each arm 23, 24 via a frame 35. As each hydraulic cylinder 34 contracts, each plate 31 moves to a standby position away from the bail 10. On the other hand, as each hydraulic cylinder 34 extends, each plate 31 is pressed against the side surface of the bail 10, and the bail 10 is sandwiched between the arms 23 and 24.

  The interval between the plates 31 at the standby position is set larger than the width between the side surfaces of the bail 10 at a predetermined ratio so that the plates 31 do not hit the bail 10 even if the bound bale 10 swells to some extent. To do.

  A controller (not shown) detects that the bail 10 has reached a predetermined position by a sensor, and sequence-controls the operation of each hydraulic cylinder 34 and each hydraulic cylinder 40 to automatically move the bail 10 from the roller conveyor 11 to the pallet 12. Transport.

  In addition, it is good also as a structure which abolishes said sensor etc. and controls the action | operation of each hydraulic cylinder 34 and each hydraulic cylinder 40 by operation of an operator.

  Next, the operation will be described.

  When the bail 10 reaches a predetermined position on the roller conveyor 11, the transfer device 20 holds the bail 10 in the pinching mechanism 30 and rotates the arms 23 and 24 by about 90 ° to thereby move the bale 10 to the roller conveyor. It is automatically transferred from 11 to the pallet 12. Subsequently, the bail 10 is released by the sandwiching mechanism 30, and the arms 23 and 24 are rotated to their original positions. Thereby, it is not necessary to transfer the bale 10 manually, and labor saving is achieved.

  As the bale 10 is transferred from the roller conveyor 11 onto the pallet 12, it rotates 90 ° together with the arms 23 and 24 and is placed on the pallet 12 as it is. There will be no hindrance.

  The gate-shaped frame 22 has a structure in which the rotating tip portions of the arms 23 and 24 are connected via the beam 25, so that the arms 23 and 24 have sufficient rigidity, and the reaction force of the sandwiching mechanism 30 causes the arms 23 and 24 to be The deformation | transformation which 24 spreads is suppressed.

  In addition, not only this but each arm 23 and 24 may be provided independently. In this case, it is necessary to increase the rigidity of each arm 23 and 24 independently, resulting in an increase in weight.

  By connecting the pins 26 and 27, which are the rotation center axes of the arms 23 and 24, by the shaft 28, it is possible to easily ensure the positioning accuracy for coaxially arranging the rotation center axes of the arms 23 and 24.

  Since the transfer device 20 is configured to transfer the bail 10 by the operation of the clamping mechanism 30 by each hydraulic cylinder 34 and the rotation of the arms 23 and 24 by each hydraulic cylinder 40, the structure is simplified, and the product Cost reduction.

  A rotary actuator or an electric motor may be provided in place of the hydraulic cylinders 34 and 40.

  The present invention is not limited to the above-described embodiment, and it is obvious that various modifications can be made within the scope of the technical idea.

  The transfer device according to the present invention can be used for, for example, one that bundles a lump of waste plastic that has been reduced by a volume reduction device such as waste plastic, and then transfers the lump of waste plastic onto a pallet on a conveyor, or other transport equipment.
