However, in the prior invention device, before being bundled with adhesive tape, the ends of the wires are simply placed on the product holder. only,
There were problems such as short objects losing their balance, and long objects falling or sliding down due to their own weight.

Problems to be Solved The purpose of the present invention is to solve the above problems.
This system securely holds string-like products such as twisted wires, strings, round bars, etc. that are successively conveyed to the product receiver until they are finished, thereby preventing errors in counting the number of products and saving labor. An object of the present invention is to provide a temporary bundling method and device that can improve the results.

[Structure of the invention]

The method of temporarily bundling string-like products according to the present invention for bundling is to use a set of product holding claws to alternately bundle string-like products such as electric wires from above, which are sequentially conveyed and placed on a product receiver with an open top. A device for carrying out this method is characterized by holding a string-like product in a product receptacle, and a device for carrying out this method is characterized in that the product holding pawl is a virtual product receptacle formed by an opening of the product receptacle. (a) traverses and partially closes the receiving space; (b) moves away from and opens the partially closed receiving space; (c) rises from the open position; (d) raises the space. (81) is provided with means for performing a wheeling operation of approaching the upper part of the receiving space from the approach position (81) and returning to the (al) position, and the set of product holding claws performs the transporting operation. It is constituted by providing means for performing alternately.

String-shaped products such as electric wires that are transported to the final product receiver are securely pressed from above one by one by a set of product presser claws that operate alternately, so that the product is held down securely from above until the product is wrapped. The product does not fall or shift from the product holder, thereby reducing errors in counting the number of products and eliminating the need for manpower, thereby promoting labor savings. In addition, the product presser claw opens away from the virtual product receiving space formed by the opening of the product holder, rises, approaches, and then descends to return to its original state. Because it performs action, there are no problems such as entanglement with the product or damage caused by pulling.
