Sheet Product Wrapping Apparatus

Abstract

The apparatus includes a clamp lever 3 by which sheet products 1 are clamped near one edges thereof after being stacked. The clamp lever 3 is rotated at an angle of 180° so that the sheet products 1 are swung and turned over by the clamp lever 3. The apparatus further includes a horizontal member 13 by which the sheet products 1 are received and supported, a press bar 14 being pressed against the sheet products 1 and then moved along the sheet products 1. The sheet products 1 are therefore pushed and smoothed out by the press bar 14. The sheet products 1 are wrapped with a wrapper 17 after being smoothed out.

Description

FIELD OF THE INVENTION[0001]The invention relates to a sheet product wrapping apparatus in which sheet products are wrapped with a wrapper after being stacked.BACKGROUND[0002]Each of Japanese Laid-Open Patent Publication No. S62-244,864 and Japanese Patent Publication No. H05-43,479 discloses a machine for successively making plastic bags. In the machine, a plastic film is fed longitudinally thereof and intermittently and heat cut widthwise thereof by a heat cutter whenever being fed intermittently, to successively make flexible plastic bags. The plastic bags are discharged successively after making.[0003]Japanese Patent Publication No. H07-67,927 discloses an apparatus in which plastic bags are stacked with each other after being discharged. The plastic bags are then wrapped with a wrapper. The wrapper comprises a plastic film. The plastic bags are fed toward and across the plastic film to be surrounded by the plastic film. The plastic film is then heat cut by a heat cutter so that...

AI Technical Summary

Benefits of technology

This invention is about a machine that makes sure sheets of product are clamped securely after they are stacked. The machine has a lever that rotates to swing and turn over the sheets, a member that supports the sheets after they are turned, and a press bar that pushes the sheets out. The sheets are then wrapped with a wrapper. There is also a vertical member that guides the sheets as they are folded. The machine can make sure the sheets are smoothed and folded evenly throughout their length. The clamp lever is positioned opposite the discharge position where the sheets are discharged, and a stopper and receiver are used to make sure the sheets are securely clamped and stacked. Overall, this invention makes sure the sheets are well-made and ready for use.

Problems solved by technology

In this case, some of the plastic bags may be slack or folded due to static electricity or air entrapment when the plastic bags are stacked with each other after being discharged.

However, some of the sheet products may be slack or folded in the same way when the sheet products are stacked with each other.
