However, in Patent Document 1, since the support member of the holding unit that supports the sheet has a structure extending from the floor on which the pallet or the like is placed, the space occupied by the floor of the sheet feeding device is necessarily large.

In particular, in the case of handling the packing of glass plates of various sizes, it is necessary to individually provide a dedicated sheet feeding device corresponding to each of the sheets having different widths, so that an increase in the floor space occupied becomes significant.

In view of the above circumstances, a technical problem of the present invention is to provide a sheet feeding device capable of reducing the occupied space of the floor as much as possible.

The present invention, which is invented in order to solve the above-mentioned problems, is a sheet feeding device, which is configured to form a glass plate laminate in which a glass plate and a sheet are alternately laminated in a vertical posture on a pallet, and is configured to form a band shape The sheet material is cut to a fixed length at the cutting position while being sent out, and the cut sheet is moved to the feeding position and is disposed on the surface side of the glass plate. The sheet feeding device includes a pair of holding units, and a As for the guide member, the pair of holding units respectively hold both ends in the width direction of the sheet, and the pair of guide members can move each of the pair of holding units between the cutting position and the feeding position. Ground support; and the guide members are suspended and supported on the fixing system above the pallet.

With this configuration, the holding unit for holding the sheet is positioned above the pallet. Suspension support is supported by the guide member of the fixing system. Further, in this state, if the holding unit is moved back and forth between the cutting position and the feeding position, the sheet can be fed and arranged on the surface of the glass plate on the pallet. Therefore, the sheet can be fed in a state where the guide member and the holding unit are separated from the floor, and the floor area can be kept small.

In the above configuration, it is preferable that the fixing system is a structure of a building located above the pallet.

In this way, it is possible to effectively use a structure of a building such as a ceiling or a beam that is liable to become a dead space. In addition, since the structure of the building is strong, it is preferable as a fixed system.

In the above configuration, it is preferable that at least one of the pair of guide members is movable in the width direction with respect to the fixing system.

In this way, even for a plurality of types of sheets having different widths, it is possible to cope with the same sheet feeding device. Therefore, it is not necessary to separately provide a dedicated sheet feeding device corresponding to the width of the sheet, so that the floor space can be further saved.

In the above configuration, it is preferable that each of the guide members is movable in the front-rear direction with respect to the fixing system.

If so, the forward and backward position of the holding unit can be adjusted by the forward and backward movement of the guide member. Therefore, even if the stacked position of the frontmost glass plate is changed due to the alternate arrangement of the glass plates and the sheets arranged vertically, the positional relationship between the glass plate and the holding unit can always be maintained constant. Therefore, the sheet can be continuously and stably supplied to the surface of the glass plate existing on the forefront side.

In the above configuration, there may be provided a plurality of pairs of the holding unit and the guide member in the width direction, and the sheet feeding device may be configured to support a single The plurality of sheets are supplied at different positions of the pallet or the plurality of pallets.

In this case, a plurality of sheets can be supplied and arranged at the same time.

In the above configuration, an auxiliary guide member that can be moved in the up-down direction along each of the guide members may be included, and the holding unit is provided to be movable in the front-rear direction along the auxiliary guide member.

In this case, by moving the holding unit in the front-rear direction along the auxiliary guide member, the position of the holding unit in the front-rear direction can be slightly adjusted according to the strain of the pallet or the number of laminated sheets of the glass plate laminate. Adjust so that accurate sheet feeding can be achieved. In this case, since the holding unit is supported by the guide member via the auxiliary guide member, the auxiliary guide member can be moved in the up-down direction along the guide member to realize the vertical movement of the holding unit.

As described above, according to the present invention, the guide member that supports the holding unit that holds the sheet is suspended and supported by a fixing system that is positioned above the pallet, so that the floor area can be minimized.
