The package lifter 4 has a holding arm 40 for holding the plate material package 1' attached to a chain.

Next, the operation of this plate packing apparatus will be explained.

The carry-in conveyor 2 is supplied with two-width plates (not shown). This two-width plate material is divided into one-width pieces by the halving machine 17, and the receiver of the loading and binding device 3 is sent onto the arm 11 by the sending device 18 with the two divided plates l lined up. . The receiver is the plate on arm 1] The receiver is the plate on arm 11
The loading table 12. is dropped by rotating it downward. be placed on top.

By repeating such operations, when a certain number of plates l are stacked on the loading table 12, the width regulating guide plate 14 operates to align the widthwise positions of the plates l, and then the strapping is carried out by the machine 16. The stacked plates 1 are bundled together. When the bundling is completed, the rollers of the loading platform 12 are driven, and the plate materials 1 are
The bundle 1 is sent forward.

In the cross-feed lifting device 4, the plate material bundle 1' carried from the loading and binding device 3 to the receiving roller conveyor 21 is pushed out onto the cross-feed belt conveyor 22 by the extrusion cylinder 23, and then laterally conveyed by the cross-feed belt conveyor 22. After that, the lifting device 24 lifts it up to the upper end position.

In the corrugated board covering device 6, the corrugated cardboards 5 are transported from the corrugated board supply device 7 onto the pushing mold 25, and the board material bundle 1' is placed on the transported corrugated cardboards 5 from the rising end of the cross-feeding lifting device 4 with the feeding cylinder 29. Bring it in. At this time, the plate material bundle 1' is carried in while sliding on the bending member 26 which also serves as a guide. Further, when the corrugated board 5 is carried into the push die 25, a hot melt adhesive is applied along both sides of the upper surface by an adhesive applicator 32. Note that the corrugated board 5 has a folded edge 2 that is easy to bend, and cuts for folding are provided at both ends. In this way, the push mold 25
When the corrugated pole and the plate bundle 1' are carried in, the plate bundle 1' is pushed into the push mold 25 by the pushing cylinder 28 (FIG. 5(A)). After that, when the push mold moving cylinder 33 is shortened, the guide/bending member 26 moves toward the push mold 25.
The upper covering portion of the corrugated cardboard 5 rising from the push-in die 25 is bent (FIG. 5(B)). When the push-in type moving cylinder 33 continues to be shortened further, the push-in die 25 moves toward the upper valve plate 27' together with the guide/bending member 26. Due to this movement of the push-in die 25, the other upper covering portion of the corrugated board 5 rising from the push-in die 25 hits the upper valve plate 27 and is bent. Guide/bending member 26
stops near the upper valve plate 27 and does not move below the upper valve plate 27.

Furthermore, while the push-in mold 25 moves below the upper valve plate 27, an end bending device (not shown) operates to fold the cardboard 5
The end portion of the plate material bundle 1' is bent and placed over the end face of the plate material bundle 1'. When the folding of the corrugated cardboard 5 is completed in this way, the upper valve plate 27 is lowered by the operation of the presser cylinder 34, and the corrugated cardboard 5 is pressed and bonded with the hot melt adhesive.

The package 1'' of the plate materials 1 that has been packed in this way is pushed out from the push die 25 onto the receiving conveyor 37 of the stacking device 9 by an extrusion device (not shown) attached to the corrugated board covering device 6. The extruded plate packs 1' are carried by the package lifting device 41 in a gate-shaped orbit as shown by the arrow Q, and are lowered onto the arrangement arm 38.The arrangement arm 38 lifts the plate packs 1''. Each time it is loaded, it moves forward and three plate packs l' are placed closely side by side. When the placement of the three plate packages I' is completed, the arrangement arm 38 descends and retreats, whereby the plate packages 1' are lowered onto the .;rent i.

A certain number of stages of plate packs 1 are placed on the bullet 8,
Bullet 8 completes 1ltl.

In this way, the cardboard packaging of the plate material 1 is carried out completely unmanned, but the installation space can be kept small due to the arrangement of each device. That is, as can be seen from FIG. 2, the corrugated board feeding device 7 is installed in line with the loading and binding device 3, and the corrugated pole covering device 6 is installed in front of it, and the corrugated board is fed horizontally from the loading and binding device 3 to the corrugated board covering device 6. Since the board material bundle 1' is conveyed by the lifting device 4, the arrangement of each device 3, 4, 6, 7 is neatly arranged.
Can fit into a small floor space.

As described above, in the board packaging apparatus of the present invention, a corrugated board feeding device is installed in line with the loading and binding device, and a corrugated board covering device is installed in front of the loading and binding device, and the board is transported horizontally from the loading and binding device to the corrugated pole covering device.
