Japanese Patent Laid-Open No. 11-347966 JP 2001-246576 A JP 2002-168216 A

  With conventional staples, it is easy to pierce a needle made of paper or fiber with a material made of a hard metal material. Some touched the edges and damaged the skin.

  Therefore, staples, that is, staples using soft materials such as paper and synthetic fibers other than metal have come out. However, how can a staple group with a set of a plurality of continuous needles be stably manufactured by using a soft and unstable staple? Is it easy to hold the set on the equipment? And, in use, how to insert and fix staples made of a soft material on an object to be locked has become a problem.

  That is, starting from the configuration of staples, how to configure and operate the staple holding device, the opening device to the locked object, the staple pressing device, the staple guide device, and the like is stable with a simple operation. It was difficult to do continuous work.

  The known technique presented by the present applicant as Patent Document 1 is that a plurality of staples made of soft materials such as paper and synthetic fibers are connected, a hole is formed in an object to be bound, and then one staple is separated and inserted into the hole. After both ends are folded and overlapped, both ends are fixed by adhesion, welding or the like.

  This is an explanation of a material such as paper, fiber, or synthetic fiber as a “bar-shaped staple formed into a plurality of U-shapes that are connected with a joint so that they can be separated with a slight force”, and the specific configuration is not clear. Therefore, when viewing the drawings, there is disclosed a configuration in which adjacent staples are connected via a joint in a continuous manner with almost no gap, and the specific shape of the joint itself is unclear.

Further, the publicly known technology presented by the present applicant as Patent Document 2 is provided with a punch needle or a presser for opening and inserting a staple made of a soft material such as copper, aluminum, plastic, or fiber into an object to be locked. Yes.
However, in this known technique, first, the presser is operated, the punch needle is pressed to open a through hole in the locked object, the staple is then aligned with the through hole, and the staple is pushed out with the same presser. It is inserted through the object to be locked and fixed by twisting or tying both ends of the staple.

  That is, in order to insert one staple, the presser must be rotated twice at the same position, and it is also necessary to confirm whether the staple tip and the through hole are coincident with each other. Even if it is carried out, it has become a structure which requires much time and labor for the operation | work which inserts a staple and fixes a to-be-latched object.

  Further, in the publicly known technology presented by the present applicant as Patent Document 3, a soft material such as paper is used as a staple, a heat-soluble adhesive is applied to the left and right ends of the staple, and the object to be locked is secured by a cutter with a cutting blade. While opening the hole, push both ends of the staple into the through-holes of the locked object at the same time, and after stacking the left and right ends of the staple, heat the adhesive to unify the staple end, thereby locking It is intended to fix things.

  However, in this configuration of Patent Document 3, when both ends of the soft staple are pushed into the locked object at the same time while making a hole in the locked object with the cutter with a cutting blade, Both end portions are forcibly escaped to the left and right outer sides, and the left and right end portions of the staples are slid and moved along the guide surfaces on the cradle toward the inside in both directions.

  In other words, the cutter with a cutting blade only guides the staples halfway, and the subsequent staples are moved only by being pushed from the rear, so that even if the staples are soft materials, a certain amount of waist is required. If it is thin and soft, there is a risk that when the cutter with a cutting edge moves to the left and right outer sides, it will shake and be pulled together to the left and right outer sides.

  In addition, each time the staple is pushed into the locked object, both ends of the cutter with a cutting edge are moved in the direction to forcibly change the posture to the left and right outside, which may cause problems with the durability and strength of the cutter with a cutting edge. Was inherent.

The present invention takes the following technical means in order to solve the above-mentioned problems.
