These oblique conveyors 3.4 and the conveyor 5 attached to the edging device 1 form a linear panel transport conveyor 6. The oblique conveyor 3.4 consists of a roller conveyor in which each conveyance roller is provided diagonally with respect to the conveyance direction, and the panel 2 is conveyed while being pressed against conveyance guide guides 3a and 4a, which are examples of the conveyance guides 3a and 4a. Parallel to the panel conveyor 6, a valent conveyor 8 is provided which conveys the pallet 7 loaded with the panels 2 in the opposite direction.

The pallet transport conveyor 8 is provided with horizontal turning parts 9.10 at the intermediate part and at the extended position of the starting end, and each horizontal turning part 9. Two consecutive delivery conveyors 11, 12 are installed with the lO turned by 90°. First and second truck guide structures 13.14 are constructed between the opposite ends of the panel conveyor 6 and the pallet conveyor 8, and a truck 15.16 is installed on each truck guide frame 13.14, respectively. It is. Each trolley 15.16 is equipped with a self-propelled device (
The gripping device 1217 has a plurality of suction pads 18 and a gripping device f 17 (not shown) and a gripping device f 17.
．． It is rotatably suspended from the lower end of a piston rod 20 of an elevating cylinder 19 installed at 1G via a joint 21. An outer frame 21a of the joint 21 is fixed integrally with the gripping device 17, has a gear 22 on its outer periphery, and is engaged with an output gear 24 of a motor 23 attached to the piston 6. The motor 23 serves as a turning device for the gripping device I7, and has a built-in speed reducer, and by driving the motor 23, the gripping device 17 can rotate 360° in forward and reverse directions. The suction pad 18 is connected to a suction device such as a suction blower via a flexible tube or the like.

Operation As shown in FIG. 4, the panels 2 are supplied to the first oblique conveyor 3 from the front side. The panel 2 has a rectangular shape, for example, the length of which is about four times the width, and is supplied with its longitudinal direction being vertical. The panel 2 supplied to the oblique conveyor 3 is
While being conveyed by the edging device 1, edging is performed on the negative long side a. The panel 2 with the edges pasted is squeezed out onto the second oblique conveyor 4, where the suction pad 18 of the cart 15 descends and is suctioned by the suction pad 18.The panel 2
The truck 15 that has absorbed the pallet (ship conveyor 8
The panels 2 are loaded onto the pallet 7 of In this way, a large number of panels 2 are sequentially conveyed to the first oblique conveyor 3, one short side a is pasted, and the panels are placed M on the pallet 7. When a predetermined number of sheets are loaded on the pallet 7, the panel 2
The pallet 7 carrying gj is conveyed to the second cart guide mechanism 14 by the pallet conveyor 8. Here, the panels 2 on the pallet 7 are sequentially unloaded by the cart 16 and conveyed onto the first oblique conveyor 3. At this time, the trolley 16 moves to the first oblique conveyor 3 f! ,! While moving to I, the suction pad 18 is rotated by the motor 23 to change the angle of the panel 2 by 90'. Therefore, as shown in FIG. 5, the panel 2 is fed by the edge-binding device 1 in a landscape orientation, and one short side is edge-bound. The panels 2 with edges pasted on the short sides are conveyed from the oblique conveyor 4 by the trolley 15 onto the pallet 7 at the starting end of the bullet conveyor 8 and loaded thereon. At this time, while the cart 15 is moving, the suction pad 18 is rotated to change the angle of the panel 2 by 90'. Therefore, the panels 2 are stacked on the pallet 7 at an angle where the longitudinal direction is along the first general feeding direction of the bullet conveyor 8, as in the previous case. In this way, each panel 2 on the pallet 7 under the second truck guide frame 14 is stacked on the pallet 7 of the first truck guide frame 13 with its short sides edged one after another.

When all the panels 2 are loaded on this pallet 7, the pallet 7 is conveyed to the second cart guide frame 13 side by the pallet conveyor 8, and from there, the panels are removed one by one on the platform 16 and placed on the first Transport it to diagonal conveyor 3. At this time, the suction pad 18 is not rotated, but the long side C of the panel 2 is facing to the left side of the figure, contrary to FIG.
Then, edge pasting is performed on the long side C. And Paburu 2
The second diagonal conveyor 4 remains in the same direction as the carriage 13.
The leaves are conveyed and laid out on pallets 7. When all the panels 2 are loaded on the pallet 7, the pallet 7 is conveyed to the bottom of the second cart guide frame 14. After this, trolley 16
While rotating panel 2 on pallet 7 by 90 degrees,
The remaining short side d of the panel 2 is hemmed using the hemming device l. In this way, when the edge pasting on the four sides a to d of all the panels is completed and the pallet 7 under the first trolley guide frame 13 is loaded, the pallet 7 is Conveyor 8 transports the shells to any horizontal turning section 9.IO, and from there one shell is taken out (withdrawal conveyor 11.12).

In this way, the panel 2 is attached to the edging device 1 at an angle of 9
It is possible to carry out circular conveyance by changing the angle by 0°, and to attach edges to the four sides a to d. At this time, the rotation of panel 2 is controlled by the carriage guide frame fJ! Since this can be done while the cart 15.16 is moving on the 13.14, the turning can be done efficiently and does not take up much space. Furthermore, since the panels 2 are stacked and stored on the pallet 7, a large number of panels 2 can be sequentially conveyed in a short tact, and efficiency is further improved. In addition, since the suction pads 18 can be rotated in both the carts 15 and 16 of the first and second cart guide frames 13 and 14, the panels 2 can be conveyed by the pallet conveyor 8 in the elongated direction as described above. It can be loaded facing the direction. Therefore, even if the puffles 2 have an elongated shape, a large number of puffles 2 can be stacked on the pallet 7 and sent by IM without taking up much space.

Further, when the panel 2 is conveyed on the second oblique conveyor 4, the panel 2 is pressed against the conveyance guide 4a and its widthwise position is determined. Therefore, by appropriately restricting the stop position to a constant position using a stopper or the like, when the panel 2 is sucked by the suction pad 18 of the truck 15, the center of the panel 2 can always be aligned with the center of rotation. Therefore, regardless of whether or not the panel 2 is rotated, the pallet 7
It can be loaded with high accuracy.

In the above embodiment, the suction pad 18 can be rotated on both of the carts 15 and 16 on both sides, but it is also possible to rotate only one of the carts 15 and 16. Also, the gripping device 17 is not limited to the suction type. It may be by means of clamping claws or the like.

Further, the present invention can be applied to various panel processing devices other than the edge pasting device.
