In order to prevent the lowest corrugated sheet from being damaged during stacking or transport to a box making machine or yard, etc., a pallet, plywood, or other sheet should be placed on the lowest level of the corrugated sheet. Plates are placed as shown in FIGS. 4 and 5. The pallet or plywood board used at this time is usually one type of board material with a predetermined width and length, and these are placed on a corrugated sheet loading truck by hand or by power (forklift, chain block, etc.). When using one type of pallet or plywood, the width of the pallet gutter or the width of the plywood may be too wide or too narrow relative to the total width of the stacked corrugated sheets, as shown in Figures 6 and 7. or

(Problem to be Solved by the Invention) Conventionally, as mentioned above, only one type of pallet or plywood board with a predetermined width and length is provided, so The width of the pallet or plywood may be too wide or too narrow. For example, as shown in Figure 6, if the width of the corrugated cardboard sheet is narrow, the space will be taken up by the size of the pallet.
Stockyard (warehouse) of stacked cardboard sheets
area efficiency deteriorates. For example, as shown in Figure 7, if the width of the corrugated sheets is too wide relative to the width of the pallet, the stacked corrugated sheets may collapse during transportation, or the ends of the corrugated sheets may protrude from the plywood. This may cause problems such as the exposed parts sagging and causing scratches.

The present invention was developed to solve the above-mentioned problems.
Always the optimal size sheet according to the sheet width to be stacked! ! It is an object of the present invention to provide a sheet loading plate supplying device capable of supplying two sheet loading plates.

The present invention provides a sheet mounting plate supplying device characterized by the above features, and is intended to solve the above-mentioned problem.

That is, in the present invention, for example, (11) prepare many types of pallets or plywood boards with different widths, and (2) select a corrugated sheet width from among the various types of pallets or plywood boards (hereinafter simply referred to as sheet mounting boards). In order to be able to use a sheet placement plate with a width commensurate with
Necessary sheet loading plates are supplied to the corrugated sheet loading truck by a suction device for picking up sheet 2ia plates that can travel in two directions: the axis and the Y axis.

(3) In addition, in order to supply the sheet placement plates to the stockyard where the sheet placement plates mentioned above are placed, we also provide a trolley for delivering the sheet placement plates and the sheets! ! A roller conveyor section consisting of multiple roller conveyors for plate storage will also be installed.

(Function) In the stockyard, sheet placement plates of various types with different widths are stacked up for each type and arranged in a predetermined order. .

At the same time, the suction device for the sheet placement plate moves onto the stockyard, and the type of sheet suitable for the width of the corrugated cardboard sheet to be manufactured among the various sheet placement plates is moved onto the suction device board, where it is The device operates to suction and grip a desired sheet placement plate from above.

After that, the suction device holds the sheet mounting plate and
The sheet is moved to the supply area to the corrugated sheet loading truck, and the sheet loading plate is released from adsorption at the same point.The unadsorbed sheet loading plate is conveyed to the corrugated sheet loading truck using an appropriate conveyance means, and then transported to the corrugated sheet loading truck. @ is placed at the bottom of the .

Here, if a track for a corrugated sheet vi carrying cart is provided between the above-mentioned supply section and an external carrying-out section, and the above-mentioned cart is directly moved to the same supply section and kept on standby, it is possible to provide other special conveyance means. It becomes possible to directly supply the desired sheet loading plate from the stockyard to the corrugated sheet loading truck.

On the other hand, separate carts are used to transport spare sheet placement plates by type to the stockyard and replenish them.
