Reciprocating insertion device

Abstract

The present invention provides a reciprocating insertion device capable of inserting contents into a large number of bag bodies in a reduced time. The reciprocating insertion device (1), in a process in which bag bodies (3) having openings (2) are conveyed in a conveying direction (T), inserts contents (4) into the openings (2). The reciprocating insertion device (1) is provided with a moving means (6) for moving, in synchronism with the speed at which the bag bodies (3) are conveyed, the contents (4) in an attitude in which the contents (4) face the bag bodies (3), an in-and-out means (8) for advancing and retracting guide horns relative to the bag bodies (3), the guide horns guiding the contents (4) to the openings (2) of the bag bodies (3), an advancing and retracting means (7) for advancing and retracting pushers relative to the bag bodies (3), the pushers pushing out the contents (4) from the moving means (6) to the openings (2) of the bag bodies (3), and a reciprocating means (9) for moving forward or in the opposite direction the in-and-out means (8) and the advancing and retracting means (7) in the conveying direction (T) at the conveying speed. In the process in which the reciprocating means (9) moves forward the in-and-out means (8) and the advancing and retracting means (7), the in-and-out means (8) and the advancing and retracting means (7) perform the following operations. That is, the operations by the in-and-out means (8) are an operation in which the in-and-out means (8) advances the guide horns until the guide horns enter the openings (2) of the bag bodies (3) and an operation in which the in-and-out means (8) retracts the guide horns from the bag bodies (3).

Description

technical field [0001] The invention relates to a reciprocating inserting device capable of inserting contents such as sheets of paper or booklets into a bag body. Background technique [0002] Patent Document 1 below discloses an article insertion device for inserting contents (articles) into a pouch. In this article inserting device, 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 pitch equivalent to 1 unit. The action of conveying the bag and the contents within a certain distance, and the intermittent operation of stopping the conveying action. Items are inserted into one bag while the two conveyor lines are stopped. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2006-232321 [0004] However, in the above-mentioned intermittent operation, there is a limit to increasing the number of bags and contents that...

Problems solved by technology

[0004] However, in the above-mentioned intermittent operation, there is a limit to increasing the number of bags and contents that can be conveyed per unit of predetermined time. For example, this article insertion device is not suitable for handling envelopes for express product advertisements (Direct Mail) at the same time. Such a huge number of bags and their contents

In addition, since there is only one bag into which an article can be inserted every time the conveying line stops, it is difficult to increase the number of contents that can be inserted into the bag per unit of predetermined time even if the article insertion device is operated at high speed. quantity
