  However, the push-out means of the prior art 1 “when the bale is taken out, the latching claw 27 is rotated by the cam portion 32 of the foot pedal 30 and hooked on the front end of the pipe 24 to connect the rod 19 to the large door 3. In this state, the large door 3 is opened, the rod 19 is pulled out, and the bale B is pushed out to the front of the compression chamber 2 by the push-out plate 14 and is removed from the restoration prevention claw 13 ”. In addition to the need for force work to be pushed out together with the opening, the structure is complicated and the manufacturing cost is also a problem.

  Further, in the case of the compression device provided with the restoration preventing claw, there is a problem that the restoring force of the processed material acts on the restoration preventing claw and becomes resistance, and the processed material cannot be easily pulled out from the compression chamber without the extrusion means.

In order to solve the above-mentioned problem, an outlet that can take out the processed product compressed from one side is provided on one side, an extraction door that can be opened and closed is provided at the outlet, and an inlet that can input the processed product is provided. A compression chamber,

It consists of a groove-side straight portion 22c having a groove 22b and a chamber-side straight portion 22d. The switching hook 22 is in a state in which the L-shaped groove-side straight portion 22c is erected while the chamber-side straight portion 22d is in a horizontal state on the press body 34 during the vertical movement including the compression operation by the downward movement of the press body 34. is there. When the push-out means 21 of the workpiece push-out mechanism 2 is operated, the switching hook 22 causes the groove-side straight portion 22c to turn to the interlocking rod 23 side to be in a horizontal state. When the groove-side straight portion 22c of the switching hook 22 is horizontal, the interlocking rod 23 is positioned between the grooves 22b at the tip. The tip of the groove-side linear portion 22c of the switching hook 22 protrudes outward from the switching arm return groove 46 when it is in a horizontal state.

  The interlocking rod 23 is provided vertically in the center of the outer wall surface facing the outlet 40 of the compression chamber 4, and a disk-shaped hook plate 25 is horizontally disposed on the upper portion near the ceiling portion of the compression chamber 4. It is fixed to the interlocking rod 23 and can be engaged with a switching hook 22 rising from below.

  The bundling device 5 includes a bundling cord roll 50 provided on the outer wall surface facing the outlet 40 in the compression chamber 4, a cord guide 52 for guiding and holding the bundling cord 51 fed out from the bundling cord roll 50, and a bundling cord And a pull-out bar 53 for pulling out.

  Next, the operation of the processed product extrusion mechanism 2 of the compression device 1 and the operations of the compression means 3, the compression chamber 4, and the bundling device 5 according to the embodiment of the present invention will be described. As shown in FIG. 7, the compression device 1 opens a loading door 44 provided in the upper half of the take-out door 41 and opens the opening 45 into the compression chamber 4 to open the plastics, plastic bottles, papers, and the like. The waste is thrown in as processed material B.

  Next, the operation panel 6 is operated, the hydraulic cylinder 33 which is the compression means 3 is operated, the cylinder rod 33b is moved up and down, and the press body 34 provided at the tip of the cylinder rod 33b is also moved up and down. Then, the processing object B in the compression chamber 4 is compressed by the descending pressure of the press body 34, and this compression operation is repeated as the processing object charging operation is repeated. When the press body 34 moves upward, the processed object B tries to be restored because the pressure from the upper side disappears. However, the processed object B is caught by the bottoms of the plurality of processed object return prevention claws 47 protruding on the side surface in the compression chamber 4 to prevent the restoration. To do.

  At this time, the switching hook 22 provided on the press body 34 is in a state where the L-shaped groove-side straight portion 22c is erected during the up-and-down movement including the compression operation by the downward movement of the press body 34. It is in a horizontal state on the press body 34. Therefore, the groove-side linear portion 22c of the switching hook 22 remains in a disengaged state with the hook plate 25 provided on the interlocking rod 23, and the interlocking rod 23 does not move up and down.

  After the compression of the processed product B by the compression means 3 is completed, the binding operation of the processed product B is started using the binding device 5. The operator operates the operation panel 6 and stops the cylinder rod 33b in an extended state, and the press body 34 stops the processed product B in a pressed state (FIG. 9). Next, the operator opens the take-out door 41, inserts the hook rod 53 into the horizontal string passing gap in the press body 34 from the outlet 40, hooks the binding string 51 on the opposite side, and hooks the string passing gap. Is taken out from the outlet 40 (FIG. 10). Next, the binding string 51 that has come out is appropriately cut and tied to the end of the binding string 51 that passes under the processed material B (FIG. 11). From this state, the operator operates the operation panel 6 to shorten the cylinder rod 33b and raise the press body 34 (FIG. 12).

  While the cylinder rod 33b is shortened and the press body 34 is raised, when the switching arm return groove 46 reaches the opening height, the elevation of the press body 34 is temporarily stopped, and the operator manually pushes the switching hook 22 manually. The groove side linear portion 22c is made horizontal by rotating around the rotation shaft 22a. The groove side linear portion 22c of the switching hook 22 protrudes outward from the switching arm return groove 45 when in the horizontal state, and the interlocking rod 23 is positioned between the grooves 22b at the tip.

  When the cylinder rod 33b is further shortened and the press body 34 is raised in this state, the groove-side linear portion 22c of the switching hook 22 engages and pushes up the hook plate 25 fixed to the interlocking rod 23 from below. As a result, the interlocking rod 23 also rises against the urging force of the return spring 27. Due to the linear rise of the interlocking rod 23, the upper end portion 24a of the swinging bracket 24 that is rotatably connected to the lower end portion of the interlocking rod 23 is pulled up and rotated around the right-angled rotating portion 24c. The part 24 b moves the extrusion rod 20 a in the horizontal direction, and moves the extrusion plate 20 in the compression chamber 4 toward the outlet 40. The processed product B bound by the movement of the extrusion plate 20 is moved in the direction of the outlet 40 and is taken out from the processed product return prevention claw 47.

  Next, when the cylinder rod 33 b is moved downward, the switching hook 22 is also lowered with the lowering of the press body 34, and the groove-side straight portion 22 c protruding outward from the switching arm return groove 46 becomes the switching arm return groove 46. And the groove-side straight portion 22c returns to the vertical state, and the groove-side straight portion 22c returns to the disengaged state with the hook plate 25. Therefore, when the switching hook 22 is in this state, there is no hindrance to the compression operation of the workpiece B due to the vertical movement of the press body 34 of the compression means 3.

  By the downward movement of the cylinder rod 33 b, the hook plate 25 is also lowered and disengaged from the groove-side linear portion 22 c, and the interlocking rod 23 is pulled downward by the urging force of the return spring 27. As a result, the upper end 24a of the swinging bracket 24 is pushed down and rotated around the right-angled rotating part 24c, and the lower end 24b moves the extrusion rod 20a to move the extrusion plate 20 in the direction opposite to the outlet 40. Return to the original position in the compression chamber 4.

  This operation is sequentially repeated, and the compression operation, the bundling operation, and the extrusion operation are repeated, so that wastes such as plastics, plastic bottles, and papers are compressed and reduced in volume.

  The present invention is used in a compression apparatus that compresses and reduces and binds wastes such as plastics, plastic bottles, and papers as processed products.
