The present invention relates to a transposer for a paper stack.

[Prior Art] A stacking process is performed as a pre-process such as a packaging process for packaging a predetermined number of paper paper laminates or a stack of these paper paper laminates to form a paper paper aggregate. Checking the number of each paper stack and the defective paper in the paper stack consisting of the supplied paper stacks, and checking and transposing these inspected paper stacks into an aligned stack Work is done.

Conventionally, the inspection and inspection of a large-sized Western paper laminate is carried out in order to inspect the number of defective papers and the number of defective papers sequentially from the uppermost paper pile of the Western paper stack that is supplied in a stacked state. However, in reality, two workers hold both ends of the paper stack and transfer it to the paper stack.

[Problems to be solved by the invention] As described above, the conventional inspection transshipment work is inefficient because two workers are all manually performed, and the paper piles are piled in a piled state by hand. It was difficult to transfer it to my body.

In view of the above-mentioned circumstances, the present invention is a stack of paper stacks that enables an operator to perform a transshipment work on a stack of paper stacks that are efficiently and accurately aligned and are in a stacked state. The purpose is to provide a replacement device.

[Means for Solving the Problems] In order to achieve the above object, the transposer for a paper stack of the present invention has the following configuration. That is, a paper stack consisting of a group of paper stacks supplied in a stacked state on the supply-side lifting table is transferred from the paper stack located in the upper stage of the paper stack to the transshipment completion position. This is a transposing device for a stack of paper sheets that is sequentially transposed on the side lifting table, and this transposing device stacks the stacked paper sheets supplied in a stacked state on the supply side lifting table from this supply position. A gripping transfer member having a transfer gripping tool capable of gripping and pulling and transferring the front end portion of the paper stack to the replacement side lifting table surface, and the supply in synchronization with the pulling and transferring operation of the transfer gripping tool. The paper stack is moved from the position to the surface of the elevating table on the transshipment side, and the transfer gripping tool grips the front end of the transfer and pulls and transfers the paper stack according to the transfer of the paper stack while supporting the lower surface thereof. Shiru Transport Tab The transfer table and the transfer gripping tool are provided with a loading and transporting member having a surface, and after the paper stack is synchronously pulled and placed and transferred from the supply position to the surface of the transshipment-side elevating table. In order to be able to transfer the paper stack on the transshipment-side lifting table surface at the transfer position, a loading transfer member supporting the lower surface of the paper stack whose front end is gripped by the transfer gripping tool. The transfer table surface is moved from that position to a position off the transshipment-side elevating table surface that can release the support state of the paper stack, and the transfer gripping tool grips the front end of the paper stack. The holding function is released and the transfer holding tool can be moved forward from this release position to a release position separated from the front end of the paper stack.

[Operation] According to the transposing apparatus for a paper sheet stack configured as described above, the inspection operator inspects the paper sheet stack located at the top of the paper sheet stacks supplied on the supply-side lifting table. ,
If the same inspection worker sequentially grips the inspected paper paper laminate and manually supplies it to the transfer gripping tool of the transfer member, the supplied paper paper stack is gripped at its front end by the transfer gripping tool. The transfer table surface of the mounting transfer member, which is moved at the same time as the transfer gripping tool is moved while being pulled and transferred, is placed and transferred while the lower surface is supported by the transfer table surface of the mounting and transfer member and is moved up and down from the supply position on the transshipment side. Transferred to the table surface.
Then, the paper paper stack transferred to the transshipment-side lifting table surface is moved from the position to the transfer table surface supporting the lower surface of the paper paper stack whose front end is gripped by the transfer gripping tool. By moving to a position where the supporting state of the paper stack can be released, the paper stack other than the front end held by the transfer gripping tool falls on the surface of the elevating table on the transshipment side waiting below. The gripping function of the transfer gripping tool that is placed and further grips the front end of the paper stack is released, and the transfer gripping tool is released from the release position and separated from the front end of the paper stack.
