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 feed operation, when the cylinder 49 is operated with the magazine 3 placed on the support rail 39, the claw portion 51 that moves upward engages the groove 5 of the magazine 3. will be combined. When the cylinder 41 is operated in the above state, the second
The magazine 3 is pitch-fed in accordance with the section width in the transport direction by the claw portion 51 that moves to the right side as shown in the figure. When the cylinder 49 is moved back after the above operation, the claw portion 51 is disengaged from the groove 5, and then the claw portion 51 is returned to its original position as the cylinder 41 moves back. By repeating the above operation, 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, the 13th
As shown in the figure, the four half cases 1 are taken out from the molding machine by the take-out device in two rows in the front and back in the transport direction, and are placed on each pedestal 65 and the support plate 95, respectively. . At this time, the support plate 95 has been moved to a height that substantially coincides with the pedestal 65 by the operation of the cylinder 85. In addition, each pedestal 6
When the half case 1 is placed on the half case 5, the rod is moved upward by the actuation of the cylinder 61. Then, the half plate placed on the pedestal 65
The half case 1 is positioned on the pedestal 65 by inserting the rod into the through hole of the case 1.
When the half cases 1 are respectively placed on the respective pedestals 65, each pedestal 65 is rotated approximately 180° in the direction perpendicular to the conveyance 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 side plate 67a - The guide plates 67 are pushed up so that they are positioned on both sides of the case 1. After the above operation, when the cylinder 61 is moved back and the rod insertion into the through hole is released, the half case 1 placed on the pedestal 65 is supported by the extrusion plate 81 that moves with the operation of the extrusion cylinder 79. It is transferred onto support plates 101 located on both sides of plate 95. At this time, the half case 1 transferred onto the support plate 101 is held between the guide plates 103 and 105. As a result, the 4
The half cases 1 are aligned in a straight line with respect to the direction perpendicular to the transport direction.

After the above operation, when each cylinder 99 is activated and the support plate 101 is moved toward the center, the two half cases 1 placed on the support plate 95 are held between the guide plate 105 and the guide plate 97. Ru.

When the rotary actuator 91 is driven after the above operation, the support plate 9
5 and the support plate 101 are rotated approximately 90 degrees. As a result, the half plate on each support plate 95 and support plate 101
The case 1 is moved into each compartment of the magazine 3 which has been moved to the transfer position so as to face up and down so that it can be loaded. 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 half case 1 held between the support plates 95 and 101 is moved downward by the contact plate 108 which rotates counterclockwise as shown in FIG. It is pushed out into each compartment of the magazine 3. After the above operation, the contact plate 10
8. The chuck mechanisms C2 are returned to their original positions, and the magazine 3 is pitch-fed by the pitch-feeding mechanism B. After the above operation, pitch feed mechanism B
is moved by one pitch in the transport direction, and the next partition 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. Then, 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 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 the front and back in the transport direction 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 and accumulate the materials in a straight line with respect to the direction perpendicular to the transport direction.

For this reason, the present invention provides a magazine that is divided into a plurality of rows in the transport direction and a direction perpendicular to the transport direction, and is transported sequentially according to the width of the partitions in the transport direction. The present invention provides a cassette/half-case auto-stocker that can improve half-case accumulation efficiency by accommodating a plurality of half-cases in a straight line in a direction perpendicular to the transport direction and transporting them to the next process. It is possible to provide
