A carry-out mechanism D is provided on the carry-out side of the automatic stacking device 11.
is placed. This carry-out mechanism D is similar to the carry-in mechanism A described above, and the same drawing number will be given and the explanation thereof will be omitted. Further, a cylinder 109 having an axis in the unloading direction is attached to the main body frame 15 according to the downward movement position of the gantry 21, and the cylinder 109
An extrusion member 111 is attached to the rod. That is, when the magazine 3 is moved to the lower position by the downward movement of the pedestal 21, the pushing member 111, which moves with the operation of the cylinder 109, moves the magazine 3 onto the carry-out conveyor provided on the carry-out side of the automatic stacking device 11. pushed out.

Next, the operation of this embodiment configured as described above will be explained with reference to FIGS. 11 to 15.

When the magazine 3 is carried into the carry-in side of the automatic stacking device 11 by the carry-in conveyor 13 and placed on the pedestal 21, the pedestal 21 is moved upward by the screw 17 which rotates as the motor 19 is driven, and the magazine 3 is placed on the pedestal 21. Moved to the upper position. When the cylinder 35 is operated in this state, the magazine 3 is clamped by the claws 37a that move toward each other. Next, when the cylinder 33 is operated in the above state, the chuck member 3 that clamps the magazine 3
7 is provided with the slider 31 is moved upward, and the pedestal 2
Magazine 3 is lifted from 1. When the cylinder 38 is operated in the above state, the magazine 3 is moved to the loading side of the support rail 39 by the slider 31 which moves to the right as shown in FIG. When the cylinder 33 is moved back at this position, the magazine 3 clamped by the chuck member 37 is transferred onto the support rail 39, and then the magazine 3 is clamped by the claw 37a by the return movement of the cylinder 35. It will be canceled. After the above operation, the slider 31 is returned to its original position by the return movement of the cylinder 38. Furthermore, the pedestal 21 is returned to the lower position by the screw 17 which rotates in the opposite direction as the motor 19 is driven in the reverse direction. In FIGS. 11 and 12 showing the pitch feeding operation, when the cylinder 49 on which the magazine 3 is placed on the support rail 39 is operated, the claw portion 51 moves upward.
is engaged with the groove 5 of the magazine 3. When the cylinder 41 is operated in the above-mentioned state, the magazine 3 in the transport direction is fed in pitches in accordance with the section width by the claw portion 51 that moves to the right as shown in FIG. When the cylinder 49 is moved back after the above operation,
After the engagement of the claw portion 51 with the groove 5 is released, the claw portion 51 is returned to its original position as the cylinder 41 moves back. By repeating the above operations, the magazine 3 is sequentially fed in pitches in the transport direction. In FIGS. 13 to 15 showing the transfer operation, when the magazine 3 is sent to the transfer position with the pitch feeding operation, four half cases 1 are simultaneously loaded into each compartment of the magazine 3. be done. That is, as shown in FIG. 13, the four half cases 1 taken out from the molding machine by the take-out device in two rows in front and back in the transport direction are placed on each receiving plate 65 and on the first support plate 95. are placed on top of each other. At this time, the first support plate 95 has been moved to a height that substantially coincides with the receiving plate 65 by the operation of the cylinder 85. Furthermore, when the half case 1 is placed on each receiving plate 65,
The rod is moved upward by the actuation of cylinder 61. Then, the half case 1 is positioned on the receiving plate 65 by inserting the rod into the through hole of the half case 1 placed on the receiving plate 65. When the half cases 1 are respectively placed on the respective pedestals 65, each of the pedestals 65 is rotated approximately 180° in the direction perpendicular to the conveying direction of the magazine 3 as the rotary actuator 59 is driven. be moved. At this time, when the push-up shaft 71 is pushed upward against the elastic force of the spring 75 as the roller 73 rolls against the cam surface of the cam 77,
The guide plate 67 is pushed up so that the side plates 67a are located on both sides of the half case 1 placed on the receiving plate 65. After the above operation, when the cylinder 61 is moved back and the rod is released from the through hole,
The half case 1 placed on the receiving plate 65 by the pushing plate 81 that moves with the operation of the pushing cylinder 79 is moved to the second supporting plate 95 located on both sides of the first supporting plate 95.
is transferred onto the support plate 101 of. At this time, the second
Half case 1 transferred onto support plate 101 of
is held between the guide plate 103 and the guide plate 105. As a result, the four half cases 1 taken out in two rows in the front and back in the transport direction are aligned in a straight line in the direction perpendicular to the transport direction.

After the above operation, each cylinder 99 is operated and the second
When the support plate 101 is moved toward the center, the two half cases 1 placed on the first support plate 95 are sandwiched between the guide plate 105 and the guide plate 97.

When the rotary actuator 91 is driven after the above operation, the first support plate 95 and the second support plate 101 are rotated approximately 90 degrees as the rotation shaft 89 rotates. As a result, the half cases 1 on each of the first support plate 95 and the second support plate 101 are moved so as to face vertically so that they can be loaded into each compartment of the magazine 3 that has been moved to the transfer position. Ru. When the cylinder 85 is moved back after the above operation, the chuck mechanism C2 is brought close to the top surface of the magazine 3.
When the rotary actuator 106 is operated in this state, the contact plate 108, which rotates counterclockwise as shown in FIG.
The half case 1 held on the support plate 101 is pushed downward and inserted into each compartment of the magazine 3. After the above operation, the abutting plate 108 and the chuck mechanism C2 are returned to their original positions, and the magazine 3 is fed in pitches by the pitch feeding mechanism B. After the above operation, the pitch feed mechanism B is driven to move one pitch in the conveying direction, and the next section is positioned at the transfer position.

By repeating the above operation, the magazine 3 with half cases 1 loaded into each compartment is moved to the support rail 39.
When the magazine 3 is moved to the unloading side, the magazine 3 is clamped by the chuck member 37 that has been waiting at that position. The magazine 3 lifted from the support rail 39 by the operation of the cylinder 33 is moved to the right side as shown in FIG. 2 as the cylinder 38 is operated. At this time, the pedestal 21 is moved to the upper position as the screw 17 rotates, and the magazine 3 is placed on the pedestal 21 as the cylinders 33 and 35 move back. Next, as the screw 17 is reversed, the pedestal 21 on which the magazine 3 is placed is moved to a lower position, and the cylinder 1
The magazine 3 placed on the pedestal 21 is pushed out onto the carry-out conveyor by the push-out member 111 that moves in accordance with the operation of the push-out member 09.

In this way, in this embodiment, four half cases 1 are taken out in two rows in front and back in the transport direction, and are taken out from each compartment of the magazine, which is fed in pitch according to the compartment width in the transport direction. It is possible to align the half cases in a straight line with respect to the direction perpendicular to the conveyance direction, and it is possible to improve the efficiency of stacking the half cases in the magazine.

For this reason, the present invention makes it possible to arrange a plurality of molded products taken out in front and back rows in the transport direction so as to be in a straight line in a direction perpendicular to the transport direction, and to input them into each section of the magazine. ,half·
It is possible to provide a transfer device for a half-case automatic stocker that can efficiently accumulate cases.
