  2. The binding machine according to claim 1 , wherein the working part is an inclined surface formed such that the direction of the force applied to the staple is neither perpendicular to the direction of movement of the driver nor parallel to the direction of movement of the driver.
  3. On the side of the driver facing the connecting body, a recess is formed that recedes toward the opposite side from the connecting body. The binding machine according to claim 1 or 2 , wherein the working portion is a surface formed at the position of the recess that is closest to the clincher.
  4. In the aforementioned connecting body, adjacent staples are connected by connecting parts. The fastening machine according to claim 1, wherein the working part applies force to the staple connected to the projection by contacting the projection formed on the staple as part of the connecting part.
  5. The staple has a pair of legs that are spaced apart from each other at the tip end. The binding machine according to claim 1, wherein the acting part applies force to the staple by contacting the leg portion of the staple.
  6. The system further includes a feed claw that, by applying force to one of the legs, feeds the connecting body toward a predetermined position within the movable range of the driver, The binding machine according to claim 5 , wherein the working part applies force to the staple by contacting the leg of the staple that is subjected to force by the feed claw.
  7. The fastening machine according to claim 5 or 6 , wherein the working part applies force to the staple by contacting the tip of the leg portion of the staple.
  8. The bundling machine according to claim 1, wherein the distance from the tip of the driver to the working part is shorter than the distance the driver travels from the first position to the second position.
  9. The binding machine according to claim 7 , wherein the working part moves beyond the position of the tip part while the driver is moving from the first position to the second position.

Description

This invention relates to a binding machine for binding objects to be bound. A binding machine is a device used to bind, for example, the opening of a bag containing fruits and vegetables, using staples. The binding machine comprises a driver that pushes the staples toward the object to be bound, and a clincher that, together with the driver, grips and deforms the staples. To enable continuous binding of objects, multiple staples are pre-connected to each other and are sequentially fed into predetermined positions within the binding machine. Patent Document 1 below describes a binding device capable of repeated binding using interconnected staples (chain clips). The multiple interconnected staples will also be referred to as a "connecting unit" below. Patent No. 3840401 Figure 1 shows the external appearance of a strapping machine according to the first embodiment.Figure 2 shows the external appearance of the strapping machine according to the first embodiment.Figure 3 shows the external appearance of the strapping machine according to the first embodiment.Figure 4 shows the bundled object with its entrance portion secured.Figure 5 shows the configuration of the staples.Figure 6 shows the configuration of a connecting body in which multiple staples are linked together.Figure 7 shows the external appearance of the strapping machine according to the first embodiment.Figure 8 shows the configuration of the part that guides the connecting body in the binding machine according to the first embodiment.Figure 9 shows the internal configuration of the strapping machine according to the first embodiment.Figure 10 shows the internal configuration of the strapping machine according to the first embodiment.Figure 11 shows the driver configuration.Figure 12 is a diagram illustrating the operation of each part of a stapler according to a comparative example when staples are fed out by the driver.Figure 13 is a diagram illustrating the operation of each part of a stapler according to a comparative example when staples are fed out by a driver.Figure 14 is a diagram illustrating the operation of each part of a stapler according to a comparative example when staples are fed out by the driver.Figure 15 is a diagram illustrating the operation of each part of a stapler according to a comparative example when staples are fed out by the driver.Figure 16 is a diagram illustrating the operation of each part of a stapler according to a comparative example when staples are fed out by a driver.Figure 17 is a diagram illustrating the operation of each part of a stapler according to a comparative example when staples are fed out by the driver.Figure 18 is a diagram illustrating the operation of each part of the stapling machine according to the first embodiment when staples are fed out by the driver.Figure 19 is a diagram illustrating the operation of each part of the stapling machine according to the first embodiment when staples are fed out by the driver.Figure 20 is a diagram illustrating the operation of each part of the stapler according to the first embodiment when staples are fed out by the driver.Figure 21 is a diagram showing the driver configuration of a strapping machine according to the second embodiment.Figure 22 is a diagram illustrating the operation of each part of the stapling machine according to the second embodiment when staples are fed out by the driver.Figure 23 is a diagram illustrating the shape of a staple. The embodiments will be described below with reference to the attached drawings. To facilitate understanding of the explanation, the same reference numerals are used for identical components in each drawing whenever possible, and redundant explanations are omitted. The first embodiment will now be described. The bundling machine 10 according to this embodiment is a device for bundling the opening portion of bags containing fruits and vegetables, and is used, for example, in the back room of a supermarket. Figures 1 to 3 show the external appearance of the bundling machine 10. Figure 4 shows a bag BG after being bound using the binding machine 10. The bag BG contains fruits and vegetables, and its opening is bound with staples 80. The staples 80 are, for example, roughly rod-shaped members made of resin. The staples 80 are wrapped around the opening of the bag BG by the binding machine 10, thus binding the opening. The object to be bound may be a bag BG as in this embodiment, but other objects may also be used. The configuration of the binding machine 10 described below can also be applied to binding machines for bundling multiple components together, for example. Figure 5 shows the shape of the staple 80 in its initial state before fastening. As shown in the figure, the staple 80 has a shape in which a pair of legs 81 are connected by a connecting portion 82, and the overall shape is roughly U-shaped. On the opposite side of the connecting portion 82, there is an open space between each of the legs 81. Thus,
