4A is sealed, and the bag body 134 containing the inner paper 5 is obtained, with the bent portion serving as the bottom portion 134B.

This bag 134 is conveyed on a conveyance path 135, and the conveyance path 135 is the conveyance path 1 of the workpiece 139.
It is temporarily stopped at a position orthogonal to 38 and fixed with a stopper or the like. Then, a pair of opening guides 142 are pushed into both sides 134A of the bag body 134, so that the cross section of both sides 134A is approximately U-shaped or V-shaped, and the bag body 134 is opened wide and one opening is The guide 142 is located below one side of the main piece 5C of the inner paper 5, and the other opening guide 142 is located between the other side of the main piece 5C and the folded piece 5.
The main body piece 5C is bent upwardly and the folded piece 5B is bent downwardly. In this state, the workpiece 139 is placed between the main piece 5C and the folded piece 5B of the inner paper 5 stored in the bag body 134.
The workpiece 139 easily and smoothly enters between the main body piece 5C and the folded piece 5B through the large opening of the bag body 134, and the inner paper 5 and the bag body 134 are integrated by the opening guide 142. As a result, the workpiece 139 is placed in the first position without causing any troubles such as misalignment, distortion, or bending of the inner paper 5.

A pressure-sensitive adhesive is applied to the cut end, and the end is bent, thereby performing a sealing operation such as closing the opening of the bag body 134.

Although the present invention is applied to a device for loading inner paper, which is a type of workpiece, into a bag, the present invention is applicable to flat paper, flat textile products such as socks, etc. The present invention is also applicable to devices that charge various types of workpieces into bags.

As described in detail above, the present invention uses a conveyor, a guide device, and a cylinder equipped with a pushing member to move the workpiece into the bag material when the conveyance device that intermittently conveys the bag material in the longitudinal direction stops conveying the bag material. Therefore, the workpieces can be accurately and efficiently loaded into the bag material without moving the conveyor, the guide device, the cylinder equipped with the pushing member, etc. in the conveying direction of the conveying device in synchronization with the conveying speed. The structure can be simplified.
In addition, since the conveyor device is equipped with a clamping device that vertically clamps the bag material together with the work over the entire length from the workpiece loading position to the fusing position, the bag material into which the workpiece has been loaded is placed at the workpiece loading position. The workpiece does not shift its position within the bag material while being conveyed from the to the melting position, and the bag body containing the workpiece can be manufactured with high precision and in good condition. Furthermore, in the clamping device, the mechanism located at the workpiece loading position of the conveying device is an intermittent clamping mechanism that releases clamping of the bag material only when loading the workpiece into the bag material.
The clamping device does not interfere with the charging of the workpiece into the bag material, and the workpiece can be easily inserted into the bag material. The present invention has the above-mentioned various advantages, and the bag containing the workpiece can be manufactured with high accuracy, quality, and efficiency, and is of great practical benefit.
