The present invention relates to a bag strap length adjusting device molding apparatus, and more particularly, to a bag strap length adjusting device molding apparatus capable of automatically producing a combination of the adjustment of the support of the bag strap length adjusting tool in a series of processes without manual process.

Ordinary bag strap length adjusting device is composed of support and adjustment.In the past, in the manufacture of the support, the support is formed by bending the support using a support molding machine, and then the material between the rolled and ejected adjustments is cut to a certain length, and the adjustment is made by hand. Was ring-shaped to the support ring.

As a result, the defect rate of the product was high, the finish of the finished product was not neat, and the competitiveness of the product was deteriorated. Gave a fatal loss.

Accordingly, the present inventors have devised a bag strap length adjusting device forming apparatus capable of cleaning the above-mentioned end and automatically performing a series of processes from forming the support and the adjustment of the bag strap length adjusting tool to mutual coupling. When described in detail with the drawings as follows.

The bag strap length adjusting device is designed to cut into the annular ring between adjustments by bending the support between the bending part between adjustments to bend both ends into annular ring shape by cutting the material between the adjustments into the proper length. It is divided into the support bending part to make it.

As shown in FIG. 1, the bag strap length adjusting device forming device 1 (hereinafter, referred to as a molding device) of the present invention has an inlet cylinder 41 and a driven roller 43 for moving the proper amount of the intermodal material W1. An arm 42 is formed on the plate 41A and is axially pinned to the forming apparatus 10 to transfer the rotational motion of the motive cam 21 to the adjusting rod W1 by the driving force. It is installed in contact with the other end is connected to the circular cam (21) and the guide (8) having a square slide groove on the coaxial line of the inlet cylinder 41 is installed horizontally in the forming apparatus (1), the bolt is fixed to the slide groove A bending punch 3 having a bending groove 5 is inserted, and a connecting rod 9 is hingedly coupled to the rear end of the bending punch 3 to fix the upper portion of the arm 10, and the arm 10 is formed on the forming apparatus 1. It is hinged to the fixed bracket 12 and has a driven roller 11 at its lower end and connected to a three-stage circular split cam 13. To be transmitted to the bending punch the rotational motion to step 3 of the split cam 13.

A bending block 4 having a bending protrusion 6 in front of the bending punch 3 is discharged in the guide 8, and the bending block 4 vertically moves up and down by a solenoid.

A striking rod (7,7 ') is inserted into the front end of the bending block (3) through the inlet hop of the side wall of the guide (8) and fixed to the upper end of the arms (39,39') axially coupled to the forming apparatus (1). And the driven rollers 38 and 38 'at the hostile positions of the arms 39 and 39' so as to be connected to the motive cams 32 and 32 'and to the upper arm springs 37 and 39'. 37 ').

With the above-described configuration, the adjustment bending portion 2 is formed, and a bending punch 16 for vertical bending of the support base material W2 is installed vertically in front of the adjustment bending portion 2 to prevent the bending punch 16 from being separated. Guides 18, 18 ′ are bolted to the molding apparatus 1 to guide the bending punch 16.

At the upper end of the bending punch 16, the driven roller 20 in contact with the circular cam 21 is configured with a one-piece spring 34 for returning the bending punch 16 after the downward movement of the installation pottery. A clamp 17 for clamping of the support material W2 is formed on the front of the bending punch 16 and fixed to the support 35 fixed by the 36, and bolted thereto, and bent directly under the bending punch 16. The block 24 is discharged from the inside of the forming apparatus 1 to be moved forward and backward by the solenoid, and a bending plate 23 is formed for adjusting the bending. The solenoid is pressed with the adjusting bending punch 3 by the solenoid. It is configured to be able to do forward and backward movement to the proper distance.

The bending member 25 is formed at the bottom of the bending plate 23 to form a bending member 25 for finishing the square in the form of a square so as to be able to move forward and backward by a solenoid and maintain a predetermined interval while maintaining the bending interval 27. The driven bites 29 and 29 'are fixed to the guides 28 and 28' and are driven by the driven rollers 30 and 30 'and the one-piece springs 33 and 33' which are connected to the driving shafts 32A and 32A '. It is formed with the brackets 31 and 31 '.

The operational effect of the present invention having the above structure is as follows.

Adjusting bending part through the inlet cylinder 41 installed in the driven roller 43 and the copper plate 41A by pushing the arm 42, one end of which is in contact with the driving cam 21 and the other end of which is connected to the driven roller 43. (2) When the inter-adjustment material W1 drawn into the slide groove of the guide 8 is settled in the proper length at the rear end of the bending block 4, the split cam 13 rotates one step, and the arm 10 And the bending punch (3) connected by the connecting rod (9) to the first advance, the inlet side of the adjustment material (W1) of the bending punch (3) cuts and slides the adjustment material (W1) to press the bending block (4) By the bending groove (5) and the bending projection (6) to perform the primary bending of the adjustment material (W1) in the return shape.

Subsequently, the striking rods 7 and 7 ', which are auxiliary means for the second bending, are driven by the driving cams 32 and 32' through driven rollers 38 and 38 'provided on the arms 39 and 39'. By hitting both ends of the adjustment material (W1) to facilitate the annular pressing operation with the bending plate 23 is a secondary bending process. After completion of the hit by the striking rods (7, 7 '), the cutting block (4) is lowered vertically by the solenoid to be locked in the guide (8) and at the same time the split cam 13 is rotated in two stages. The bending punch 3 performs the second forward movement to form the adjustment section 51 forming a complete annular shape by pressing the bending plate 23 which is advanced by the solenoid in the advancing direction of the bending punch 3.

The bending punch of the support bar bending part 15 located in front of the bending part 2 by adjusting the bending punch 3 while the division cam rotates three steps of the adjustment bar 51 shape | molded in the annular shape by the above process. The adjusting section 51 is inserted into the central space between the 16 and the bending member 25.

At the upper end of the inserted adjustment, the support bending punch 16 vertically moves by the motive cam 21 and the driven roller 20, and the support material W2 of the bending punch 16 is supported by the support material W2. Cutting the support material (W2) with the clamp 17 and pressing the support material block 26 to the support material (W2) While forming into a shape, it is inserted into the annular ring of the adjusting section 51 and squared by bending both ends of the support material W2 with the bending bites 29 and 29 'by using the lower bending member 25 as a bending jaw for bending. The bag strap length adjusting device 50 is molded and the support bending punch 16 is lifted, the clamping of the support 52 fixed to the front of the bending punch 16 is released, and the support block 24 and the bending member 25 are The solenoid is retracted and the bag strap length adjusting port 50 is dropped into a bucket [not shown] installed at an enemy position and then transferred to the next process.

Bag strap length adjusting device molding device having the configuration and action effects as described above is a very useful design that can reduce the defect rate and labor costs by automatically producing a series of processes without manual work to play a role in strengthening corporate competitiveness It can be said.
