Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is a method for filling 40 icg, 50/cg, and 60 icg bags (commonly called jute bags), and then threatening the mouth of the bags. This relates to a device for sewing.

[Prior art] Traditionally, grains such as rice and wheat are packed in jute bags or, in recent years, coarse bags woven with synthetic side fat stretched tape, usually weighing 60 kg.
On this day, the pieces are packed in g and held by a pair of grippers, transported horizontally, and the edges are sewn using a sewing device such as a sewing machine. This type of bag is breathable, has 3774 threads, and can be used several times (approximately 4 to 10 times) after being unraveled and fenced, and will not break even if the bag filled with grain is scooped up into multiple layers. It is widely used because it has many advantages such as:

[Problems to be solved by the invention 5] However, since this type of squeezing is uncollected, it is difficult to feed grains, etc., to a device position by holding the mouth rim between a pair of grippers after a predetermined condition. Then, the rim of the bag above the position where it is held by the gripper hangs to either the left or right, and -
Since the sewing thread becomes paralyzed or incapacitated, usually one person is present at this -N device, and the upper part of the ribbon that is fed into the sewing device with the manual sewing thread is held upright from the gripper. It is troublesome and dangerous to create rows near the conveyor that transports the filled bags, and if safety devices are installed, these devices will increase the cost of the equipment and increase the cost of the equipment.
It becomes a practical ratio.

This approach completely eliminates the need for manual stitching when a bag is inserted into a sewing machine to seal the opening by sewing.

Even if the bag is flexible, the upper part of the bag that protrudes above the gripper will stand up as the bag is transported, ensuring that the Mffi device seals the bag in a beautiful manner. The purpose is to

[Means for solving problems]
