[Problem that the idea aims to solve]

Recently, the band b used in binding machines is designed to easily conform to the external shape of the object to be bound. There is a tendency to switch to thinner and thinner materials for reasons such as

[0006] Therefore, when the thin band b is sent out from the feeding mechanism e, the guide tube f and If a slight feeding resistance occurs due to a band guide, etc., this band Since the band b is buckled under the compressive load in the direction, the band b gets stuck at the outlet side of the feeding mechanism e and There was a problem that the band could not be supplied to the band guide.

[0007] Considering the conventional circumstances, this idea is designed to prevent buckling even if the band is thin. Band feeding system in the binding machine that enables smooth band feeding without any problems. The purpose is to provide a

[0008]

[Means to solve the problem]

The band feeding device in the binding machine of this invention consists of a driving roller and a driven roller. from a band feeding mechanism and a guide tube provided near the outlet of this band feeding mechanism. One of the driving roller and driven roller has a convex surface and the other has a concave surface. By forming a flat band and placing it with a gap between the two, a flat band can be curved. A hole type is configured to allow the band to be fed out in a bent state, and the inside of the guide tube has a hole shape that allows the band to be fed out in a bent state. A support edge is formed to maintain the structure.

[0009]

[Effect]

The flat band is guided in an arched shape by the hole type of the band feeding mechanism. The band guide is fed into the tube, and the guide tube maintains this curved state as it is. By feeding the band to the side, smooth band feeding is performed without buckling.

【Example】

An embodiment of this invention will be described below with reference to the drawings.

[0011] The band feeding device 1 shown in FIGS. 1 and 2 is suitable for a binding machine 51 as shown in FIG. It is used.

0012 This binding machine 51 has a guide frame erected in an arch shape from both sides of a binding table 52. A band guide 54 is held inside the body 53 by appropriate means, and this band guide A protrusion support edge 14 and a step support edge 15 similar to the guide tube 5 described later are formed on the inside of the guide tube 5. It is. In addition, near the entrance 54a of the band guide 54, a band feeder of this invention is provided. A device 1 and a known heat welding cutting mechanism 55 are provided, and both of the heat welding cutting mechanism 55 Both ends of the band guide 54 are connected to the sides. 56 is a band pool box. 57 is a band reel, and this band reel 57 includes a band reel. A band pullback mechanism (not shown) for reversing the movement of the band 57 is connected.

[0013] The band feeding device 1 keeps the band B in a state that does not buckle the band guide 54. This is a band feeding system consisting of a driving roller 2 and a driven roller 3. It consists of a band feeding mechanism 4 and a guide tube 5 disposed near the outlet of the band feeding mechanism 4. ing. 6 is a drive machine connected to the drive roller 2 via a transmission mechanism 7 such as a chain. ing.

[0014] Either one of the driving roller 2 and the driven roller 3 (in this embodiment, the driven roller The roller 3) has an arc-shaped convex surface 8, and the other (in this embodiment, the drive roller 2) has an arc-shaped convex surface 8. By forming a concave surface 9 and arranging both 8 and 9 with a gap C, a flat plate is formed. A hole die 10 is configured for sending out a shaped band B in an arched curved state (see Fig. 1). It is.

[0015] In the guide tube 5, the band B fed out from the band feeding mechanism 4 is placed in a band guide 54. This is to maintain the curved state of band B until it enters the upper half 11 and The lower half portion 12 is coupled with bolts or the like.

[0016] The upper half 11 is provided with a protrusion 13 projecting downward from the center position. Thus, a protruding support edge 14 for pushing down the center portion of the band B is formed. The lower half 12 includes a central bottom surface 15 and stepped surfaces 1 provided on both sides of the central bottom surface 15. 6, two stepped support edges 1 for upwardly supporting both ends of the band B. 7 is formed, and the bump is formed by each step support edge 17 and the protrusion support edge 14. The car is supported at three points so that it can move forward while maintaining an arcuate curved state. Ru.

[0017] Next, the operation of the above embodiment will be explained.

[0018] In FIG. 4, when the objects W to be bound are carried onto the binding table 52, the band is fed. The band B stored in the band pool box 56 by the device 1 is transferred to the band pool box 56. It is sent toward the entrance 54a of the id 54.

[0019] At this time, the band B is curved into an arcuate shape by the hole mold 10 of the band guide feeding mechanism 4. Then, it is fed into the guide tube 5. In this guide tube 5, the band B is in step with the protrusion support edge 14. While being supported at three points by the differential support edges 17, 17, the band maintains an arched curved state. Enter the entrance 54a of the guide 54.

[0020] Therefore, the band B fed out from the band feeding mechanism 4 is curved in an arcuate shape. Since a large compressive load can be tolerated, feeding resistance can be reduced by the guide cylinder 5 and band guide 54. Smooth band supply all the way to the end of the band guide without buckling even if resistance occurs will be held.

[0021] After that, the band B passes above the heat welding cutting mechanism 55, and the tip part is cut by an appropriate hand. When held in the stage, this band B is pulled back by a band pull-back mechanism (not shown). By being strongly pulled back by the reversing operation of the reel 57, the binding table 52 is After being tightly wrapped around the object W to be bound, the band is joined by the thermal welding cutting mechanism 55. Heat welding treatment is performed on the joint portions and cutting treatment is performed on the portions where the band is not needed.

[0022] In addition, the convex surface 8 of the above embodiment is shaped into the driving roller 2, and the concave surface 9 is shaped into the driven roller 3. Alternatively, the hole shape 10 composed of the convex surface 8 and the concave surface 9 may have an arcuate shape. It may also be Yamagata.

[0023]

[Effect of the idea]

The band feeding device in the banding machine of this invention consists of a driving roller and a driven roller. A band feeding mechanism and a guide tube installed near the exit of this band feeding mechanism. One of the driving roller and driven roller has a convex surface and the other has a concave surface. By forming a flat band on the surface and placing them with a gap between them, a flat band can be curved. A hole type is configured to feed the band in a curved state, and the inside of the guide tube is designed to record the curved state of the band. Since the band has a supporting edge to maintain the It is fed out curved in an arcuate shape according to the hole shape of the mechanism, and this curved state is maintained in the guide tube. Since it is maintained as it is, even if there is feeding resistance in the guide tube or band guide, the feeding direction will be maintained. Smooth band feeding occurs without buckling.

[0024] Therefore, the clogging of the band, which occurs frequently in the past, can be easily resolved. , which has the excellent advantage of significantly improving the workability of bundling work.
