Description

Automated polyproplylene sack manufacturing system capable of insertion and sewing of individual straps on both sides of the opening}

The present invention relates to an automated sack manufacturing apparatus capable of inserting and sewing individual strings on both sides of an opening of a sack, and more specifically, since a conveyor transport method is limited to a horizontal transfer system, it is impossible to insert and sew a string on both sides of an opening of a sack. Thus, unlike the existing technology, which was all done manually, the conveyor is switched from horizontal to vertical to enter the stand, transporting the opening toward the upper side, dividing both sides of the opening close to each other from side to side, and then inserting the string. A fold that spontaneously folds in a state in which the string is embraced by passing through a pair of tapered pipes, and a pair of sewing machines installed at the rear of each taper pipe immediately sews and discharges both sides of an opening drawn out from the tapered pipe. The present invention relates to an automatic stand fabrication device capable of inserting and sewing individual strings on both sides of an opening.

In general, hemp refers to a large sack woven from coarse and coarse twine, sometimes referred to as hemp sack or turret sack. These sacks are mainly used to store grain or to dispose of soil or garbage.

The above-used sacks are provided with a function to open and close easily and quickly by installing a zipper in the opening, but when purchasing them in large quantities, they are mainly used when they are used in large quantities or because they are used for one-time use due to the burden on the purchase cost. Use a string with a string inserted into the opening.

As in the above, as the conveying method of the conveyor is limited to the horizontal conveying method in the manufacturing process, the rope is inserted into both sides of the opening of the sack and cannot be sewn.

For example, the public utility model publication 20-2001-0020656 "PP Paddle Production System" is published as an example of the pavement manufacturing apparatus as described above, and the prior art has a paddle feeder supplying a PP paddle wound in a roll form, It consists of a tension adjusting part to adjust the tension on the supplied bag, a cutting part to cut the supplied bag to a certain size, a printing part to print one side of the PP bag, and a sewing part to sew an opening on one side of the PP bag, In particular, the above prior art proposes to iron a surface of a carriage being transported on a roller by inserting a heating wire into a plurality of rollers constituting a tension adjusting unit so that heat is released.

As can be seen from the above prior art, only the technique of sewing one side of the stand is described, and the technique of closing the opening cannot be found. That is, in order to insert a string or attach a zipper to the opening, the operator is forced to sew manually or supply it to a separate sewing device to manufacture.

On the other hand, to solve the above problems and developed a technique for automatically sewing the zipper in the opening. As an example, the public utility model publication No. 20-1995-0039102 "Zipper automatic sewing machine for the pipidae" is published, and the related art has vacuum pads provided on both sides after dividing the folds of the opening by thermal cutting. It is a device that separates the left and right sides of each of the divided openings and separates the folds into the tapered fallopian tubes, and performs folding by placing a pair of zippers on the folds and closing with a sewing machine.

However, when dividing the opening using only a vacuum pad as in the prior art, frequent defects occurred because the same adsorption was not performed every time due to the characteristics of the material of the sack, and the above technique is a technology limited to zipper sewing. It was not possible to manufacture this inserted ledge.

Accordingly, there is an urgent situation in which the opening of the opening is more completely divided to reduce the defect rate of the product during manufacture, and it is possible to automatically insert the string.
