In general, a buffer material such as a slip sheet or resin powder, or a partition member such as a spacer is interposed between glass plates.

  In addition, these spacers are properly used depending on the shape, purpose, application, etc. of the glass plate, and many methods and apparatuses for loading a glass plate on a pallet using these spacers have been proposed and known. In most cases, a slip sheet or a spacer is used for the plate.

  For example, Patent Document 1 discloses an apparatus that supplies slip sheets one by one to a glass plate being transported from a state in which a large number of slip sheets are stacked.

  If the interleaf paper is significantly larger than the size of the flat glass product, when the flat glass products are stacked and stacked vertically, the interleaf that protrudes above and below the flat glass product will unnecessarily enter between the flat glass products, making packing difficult. The slip sheet is usually cut according to the size of the flat glass product.

  For this reason, it is necessary to prepare slip sheets for each type of flat glass products such as window glass for automobiles, which requires a wide storage space, and management of slip sheets is difficult. is there.

  Without preparing the slip sheet cut according to the size of the sheet glass product, the slip sheet is pulled out from the roll rolled in the slip sheet and cut into the length of one sheet glass product while the sheet glass product being transported is cut. Patent Document 2 discloses a method for supplying slip sheets on top.

It is a method of supplying slip sheets without stopping the glass plate to the glass plate moving on the conveyor, but it is difficult to move horizontally for bent plate glass products used for automobile windows etc. It is difficult to use the method disclosed in Patent Document 2.
