FRONT STOPPING DEVICE, SHEET LAYERING DEVICE, COUNTER-EJECTOR, AND CARTON FORMER

摘要

The purpose of the invention is to stop a variety of sheets while absorbing the impact and to prevent problems generated by sheets colliding with a front stopper while in a state of being inclined to the front or rear. A front stopping device that receives sheets being sent along a horizontal transport route on a hopper unit and stops the movement in the direction of travel comprises: a plate-shaped buffering member (101) which is directly contacted by the front part of a sheet (10); and supporting members (103, 104) that supports the upper end and lower end of the buffering member (101). The buffering member (101) is formed of a flexible material to absorb the kinetic energy of the sheet (10) by elastically deforming into a concave shape when receiving the front part of the sheet (10), and the buffering member (101) is supported by being inclined up or down by the supporting members (103, 104) so that the restoring force that pushes back the front part of the sheet (10) due to the restoration of the elastic deformation contains a vertical component.
