DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given below with reference to the drawings. FIG. 1 shows the whole of the device according to the present invention for each mechanism step by step, and a large number of carrying hands A are stocked in one stock part 3 of the device. Each of the carrying hands A is attached to each of the front and rear edges of the opening of the bag B, that is, two per bag, but there is no distinction between the front and the back and they are the same. As shown in FIG. 4, the shape of the carrying hand A is a band-like shape and is made of plastic, and the inner piece d and the outer piece which are respectively placed inside and outside the bag to sandwich the opening edge of the bag at both ends. e is provided, and both pieces d and e have a fitting means f including a protruding shaft and a hole into which the protruding shaft can be fitted. Numerals g and g ′ are binding means for opening the bag body, which are provided inwardly on the inner piece d.

[0006] The above-mentioned carrying hands A are vertically aligned in the stock portion 3, and a picking member 5 having a suction cup 4 provided on the stock portion 3 is provided on the surface of the band-shaped portion of the carrying hand A. It is picked up by suction, the transfer member 6 moves to it, the central part of the band-shaped part is held by the clamp 7 and conveyed to the front end part, and the sliding rod 2 is provided there, which is composed of a pair of parallel left and right rails. The engagement piece D at the lower end is locked. While the carrying hand A is being passed from the stock portion 3 to the sliding rod 2, the orientation discriminating mechanism 8 discriminates which direction the binding means g, g'of the fitting piece D is facing. In FIG. 3, 8a is a window for arranging the binding means g (g ') protruding from the fitting piece, 8b is a detection section for applying a beam of light to the binding means g, and one surface of the fitting section D is the window 8
When the projection of the binding means g blocks (or is not blocked) the beam light when it is applied to a, it is determined as the correct direction (FIG. 3). When the orientation is different, the orientation is reversed and the sliding rod 2 is locked.

A bending frame mechanism 10 is installed in front of the sliding rod 2. A hand 9 is provided to pass the carrying hand A from the sliding rod 2 to the bending frame mechanism 10, and the carrying hand A is moved inwardly from the position on the sliding rod 2 by the hand 9. Since the bending frame mechanism 10 bends the carrying hand A in a substantially horizontal U shape, a bending die member 13 having upper and lower ruler surfaces 11 and 12 provided in parallel at intervals for attaching the fitting piece D to the bag body B is used. , The ruler surface 1 from the outside of the middle part of the carrier
It comprises a bending frame 16 having inner surfaces 14, 15 for pressing and bending against 1, 1. In FIG. 4, 17 is a bending frame 16.
The cylinder 18 is attached to the bending die member 13 by a piston shaft for advancing and retracting the guide rod 19 and
To move back and forth in parallel.

Both ends D of the carrying hand A bent laterally in a substantially U-shape by the bending frame mechanism 10 project forward from the bending mold member 13, and in this state, the vicinity of the fitting piece is clamped from the outside by the clamp 21, 22 is held by the holding mechanism A, and the carrying hand A is held by the relay mechanism 20.
(Fig. 5). The relay mechanism 20 includes a movable base 24 capable of reciprocating on a rail 23 installed in front of the sliding rod 2 and a rotary base 25 capable of rotating laterally or upwardly to the rail 23, and fixed on the rotary base 25. Clamps 21 and 2 with a spacing of
2 is attached.

Therefore, the carrying hand A is passed to the relay mechanism 20 in a horizontal U-shaped posture, converted into a downward U-shaped posture, and carried forward by the rail 23 (FIG. 6). Two
Reference numeral 6 denotes a drive unit for opening and closing the clamps 21 and 22.

At the tip of the rail 23 of the relay mechanism 20, there is set a carrying hand mounting position F for the bag B sent from a direction substantially orthogonal to the rail direction. A setting mechanism 30 is provided for carrying the carrying hand A. The setting mechanism 30 has an arm 34 whose front end can reciprocally rotate between the rail end and the mounting position F of the rail, and the inner piece d of the fitting piece D is located above and inside the bag body B. A pair of claw pieces 31 and 32 for holding from above are attached to the arm 34 so as to be able to move up and down. Reference numeral 33 is a cylinder piston for moving up and down, and 35 is a lifting guide rod. The holding claw pieces 31 and 32 are openably and closably provided on the protrusions 36 and 36 in the vertical direction that form grooves in which both sides of the fitting piece D are fitted. Reference numeral 37 denotes a holding head for the fitting piece D, which is provided on the left and right of a base material 38 attached to the arm 34 so as to be able to move up and down.

Therefore, the carrying hand A is at the tip of the rail 23,
The arm 34 is received by the descending set mechanism 30.
Is rotated and carried to the mounting position F of the carrying hand,
At the position F, the bag is lowered to the opening of the bag B.

A pressure mechanism 40 having cylinders 41, 42 for approaching the setting mechanism 30 lowered to the opening and pressing the fitting piece D is provided at the mounting position F of the carrying hand. The piston cylinders 41 and 42 are mounted on support members 43 and 44 that are vertically rotatable in the left and right directions so as not to hinder the movement of the bag body B, and are provided at the tips of the respective pistons. The pressure plate 45 presses the fitting piece D toward the holding head 37 (FIG. 8). An attachment hole C is formed in advance at the mounting position of the bag body B on the mounting side, the inner piece d of the fitting piece D is arranged inside the bag body, and the outer piece e is arranged outside the bag body. The protruding shaft of the fitting means f formed in e passes through the mounting hole C and fits into the fitting hole, and the bag body at the opening is sandwiched and mounted.

In the above-mentioned device according to the present invention, the sliding rod 2, the bending frame mechanism 10, the clamp 21 of the relay mechanism 20,
22, the claw pieces 31 and 32 of the setting mechanism 30 and the pressing mechanism 4
0 is configured such that the carrying hands A can be simultaneously attached to the front and rear surfaces of the bag body B (see FIG. 8). Also,
Pneumatic pressure is used as a drive source for operating each of the mechanisms 10 to 40. From the stock portion 3 to the mounting position of the carrying hand, each part has one carrying hand A (two if the front and rear sides are focused). It is configured to operate in a chain for sending. However, manual operation may be arbitrarily performed at a portion where the direction of the carrying hand A can be discriminated and other assistance can be added manually.

As described above, the carrying hand A is bent into a substantially U-shape from a large number of stocked positions, is carried to the carrying hand mounting position while maintaining its posture, and the fitting piece D is held at the same position. It is attached to the bag body B. Although the attachment of the carrying hand A to the bag body B can be completed in a short time, after that, the bag body B advances from the carrying hand attachment position, and the next bag body B moves to the same position and is attached. Stop for a short time until completion.
