Bag making and inserting device

Abstract

The present invention provides a bag making and inserting device which can, while sequentially producing bag bodies, continuously perform steps in which contents are inserted into the bag bodies. Also provided is a bag making and inserting device capable of inserting a doubled number of contents into bag bodies in a predetermined unit time. A bag making and inserting device is provided with a film supplying means (2) for forming a band-like film (18) into a shape in which the film is folded double in the middle in the lateral direction thereof so as to be superposed on each other and discharging the film (18) in the longitudinal direction thereof, a bag making means (4) which forms bag bodies by pressing a heat cutter (24), which extends in the lateral direction of the film (18), to the middle in the longitudinal direction of the film (18) to thermally fusion-bond together the superposed portions of the double-folded film by heat of the heat cutter (24) and then cutting the middle in the longitudinal direction of the film (18), a conveying means (6) for arranging the bag bodies in a line and conveying the bag bodies in the direction of the arrangement, a moving means (8) for moving contents respectively facing the bag bodies at a conveying speed synchronized with the speed of the bag bodies, inserting means (10) advancing and retracting pushers relative to the bag bodies, the pushers being arranged in a conveying direction (T) in which the bag bodies are conveyed and pushing out the contents from the moving means (8) to the bag bodies, and a reciprocating means (12) for moving forward or returning in the opposite direction the inserting means (10) in the conveying direction (T) at the conveying speed.

Description

technical field [0001] The present invention relates to a bag making and inserting device capable of forming a bag body of a desired size and inserting contents such as sheets of paper or booklets into the bag body. Background technique [0002] Patent Document 1 discloses an article insertion member for inserting contents (articles) into a pouch. In this article inserting unit, the bags and the contents are arranged in a row at equal intervals on two conveying lines, and the two conveying lines perform the following intermittent operation, that is, repeating the operation at a distance corresponding to one unit pitch. The action of conveying the bag and contents, and stopping the conveying. During the period when the two conveying lines are stopped, the articles are pushed into the bag body by the pusher. [0003] However, the size and aspect ratio of the contents vary, and the number (thickness) of contents inserted into one bag is not constant. Therefore, it is difficu...

Problems solved by technology

In addition, since there is a limit to the operating speed of the pusher, it is not possible to increase the number of contents that can be inserted into the pouch per unit of predetermined time only by increasing the above-mentioned conveying speed.
