The operation with such a configuration will be described. The NO, width, depth, height, and other shape / dimension / number of the rectangular parallelepiped case W, and the stacking direction on the pallet are stored in advance in the storage device of the control device 21. The pallet P is placed on the center of the pallet table 121 by a forklift, a conveyor or the like. When the NO of the case W to be stacked is determined, the control device 21 reads the stored related data and, based on the data, the servo motor 24 is instructed by the control device 21 to stack the case W from the front right corner (a) of the pallet. Is driven to position the X table 23 at the right end in the X axis direction. In this case, the swing conveyor 68 is inclined.

Further, the ball screw 22 is driven by the servo motor to position the Z table 19 at the first step height position on the pallet P. Further, the servo motor 82 is driven to position the Y-axis conveyor at a position at a predetermined distance from the case contact plate 126, that is, at the front end position where the case can be sent to the position (a). Then, the case contact plate 126 is closed. The case W is placed on the rollers 3 of the case loading conveyor 2 rotated by the chain driven by the motor 4 manually or by another carrying means. While the case W is being fed, the air actuator 8 operates to bring the lever 7 into contact with the stop plate 9 to regulate the flow path.

Next, when the sheet is to be fed in a portrait orientation, the lever 12 is pushed out by the air actuator 13 onto the flow path by a command. If it is sent horizontally, the corner of the case W comes into contact with the lever 12 and is swung, and the direction of the rectangular parallelepiped is corrected to be vertically long. The case W sent by the case loading conveyor 2 is mounted on the auxiliary rollers 58a, 58b which are inclined to the roller 3 by a half of the oblique angle of the swing conveyor 68, and the direction thereof is changed by the rotation of the motor rollers 3a, 3b. It is changed and sent by the endless belt 66 of the swing conveyor 68 and placed on the forks 73.

The forks 73 are rotated by the weight of the case W against the force of the compression spring 78, and are transferred onto the motor roller group 69 which is arranged on the U-shaped support 46 in an inclined manner. Furthermore, the triangular portion of the bottom plate of the U-shaped support 46 at the tip hides one side of the taper roller 87 by the oscillating conveyor 68 in which the taper roller 87 receives first, and the inclination of the case is corrected by the outer taper roller 87 that appears. The case receives a component force toward the center. At this time, the air actuator 9
By the operation of 1, the L-shaped lever 88 is momentarily swung to bring the roller 89 to the upper position and receives the fall of the case W, and corrects the case W, which faces diagonally, in the Y-axis direction more accurately. In the case of continuous operation, the next case is sent in sequence while the previous case is being stacked.

When the orientation of the case W is corrected, the L-shaped lever 88 pivots to bring the roller 89 to the lower position, and the case W
Are transferred onto the Y-axis conveyor 81. Motor roller 84
Case W sent by pushes up the swing 104 and the protruding piece 1
The displacement due to the turning of 06 is detected by the non-contact sensor 107 and sent to the control device 21 to confirm whether the case of a predetermined height has been sent. On the other hand, at substantially the same time, the timer is activated by a command corresponding to the width of the case to activate the air actuator 114 for a short time to move the mover 111, and the L-shaped lever 113 of the primary centering device 110 is spaced so that the swing conveyor 68 is operated. Thus, the case that has flown with a deviation is regulated to the center of the Y-axis conveyor 81 to facilitate the flow.

Motor roller 84 on the upper stage of the Y-axis conveyor
The case W dropped further is transferred to the delivery plate 93, abuts on the guide plate 117 for performing the secondary centering, and is stopped without overrun. The delivery plate 93 is retracted by a predetermined amount by the servo motor 96, and the case W is caught by the upper motor roller and dropped onto the transfer plate 98.

Then, in response to a command from the controller 21, the delivery plate 93 is moved forward while pushing the case W to a position away from the case contact plate 126 by the case length L ₁ . During this process, the case is secondarily centered by the guide plate 117, and the guide plate 117 is expanded against the spring 116 and slides on the transfer plate 98 until it comes into contact with the case contact plate 126. At this time, the next case is dropped on the delivery plate 93. Then, the servo motor 99 operates according to the command, and the transfer plate 98 returns slightly more than the case length L ₁ to drop the case W onto the pallet P at the (a) position. Then, the feed screw 22 is rotated by a command from the control device 21, the Z table 19 is raised by the height of one case, and the second stage is stacked. In this way, a predetermined number of cases are sequentially stacked at the position (a) to form a column.

In response to a command from the control device 21, the X-axis servomotor 24 is driven to move the X table 23 by one width of the case W to the (B) position. At this time, the front end position of the Y-axis conveyor 81 is corrected by the angle change of the swing conveyor. Similarly, the next case W is stacked on the pallet P at the (b) position. When (a), (b), (c), and (d) are stacked in sequence and the stacking of several stages in the front row is completed, the Y-axis conveyor 8
In No. 1, the servomotor 82 is driven by a command from the control device 21 and is retracted by the length of the case W, and similarly, rods are stacked from the second row. In this way, when the stacking of a predetermined amount of cases on the pallet P is completed, the case contact plate 12
6 is driven by a motor (not shown) to rotate the wire 128 and open on both sides. The forklift carries pallet P away and replaces it with the next empty pallet.

Further, the turning point of the swing conveyor 68 will be described. The swing conveyor 68 is swung by the movement of the X table 23. Gear groups 54a, 54b, 56 that mesh with the sun gear 53 by turning the U-shaped support 52 on the case loading conveyor side
The auxiliary rollers 58a and 58b supported on the shaft centers of the gears 56a and 56b are rotated by a predetermined angle to rotate the auxiliary rollers 58a and 58b by half the swing angle of the swing conveyor 68 to correct the flow direction of the case. The support shaft 47 of the U-shaped support 46 on the front side of the swing conveyor 68 is supported by the midpoint of the connecting plate 38 of the U-shaped lever 37, and the center of the connecting plate 34 of the U-shaped lever 37 is the same. Since it is connected at the center of the connecting bone plate 32 of the arm 27, the U-shaped lever 37 is connected to the lever 43 as shown in FIG. 3. Therefore, as shown in FIG. Is located closer to the center of the machine than the center of the Y-axis conveyor 81 and prevents the case from popping out from the Y-axis conveyor.
