By the way, most pickles on the market are generally put in a polyester bag together with pickle juice, and the opening is sealed. Due to the necessity of heightening, a binding process is performed to shape the mouth side of the bag into a drawstring shape. In the past, aluminum wire was used as the binding material.However, not only is aluminum wire becoming an industrial waste after opening, but due to aluminum food hygiene problems, it can be replaced with adhesive tape such as polyester. It is supposed to be. Usually, the winding of the adhesive tape is performed manually, or the winding of the tape is mechanized, and the bag is manually inserted into the tape winding machine to perform the binding operation. Therefore, work efficiency is low, and improvement in work efficiency has been demanded. Therefore, it is conceivable to use a binding device as disclosed in Japanese Patent Publication No. 7-55693 as a binding device for bags. However, since the above-described object is intended to bind a bundle of a material that is relatively hard to deform such as a wire harness, this is used for binding a material that is easily deformable such as a polyester bag. Then, when the bag is pushed into the recess for receiving the object to be tied (bag), the bag is easily deformed, so that a part of the bag may protrude from the recess and may not be well bound. There is a problem. Also, it is still necessary to manually supply bags to the device,
