The present invention relates to an apparatus for manufacturing a bundle of strings for tying the stems of crops to a support, and more particularly, to an apparatus for manufacturing a bundle of strings by cutting a raw material wound on a shaft to a predetermined width. .

Semi-automatic tie-downs have been developed to bind the stems of the crops to the posts. A roll bundle bundle is used for this binding mechanism.

Conventional apparatus for producing such a bundle of bundles has been produced a bundle of bundles by cutting a wide plate-like material using a plurality of blades, and rewinding each cut material to the shaft tube.

However, such a conventional device not only takes a lot of manufacturing time, but also has a cumbersome problem of rewinding the cut material.

Accordingly, it is an object of the present invention to provide a device that can manufacture the bundle of bundles in a simple process to solve the above drawbacks.

The purpose of this is to produce a binding string bundle by cutting a predetermined width from a raw material wound on a wide plate-shaped material around a shaft, the means comprising a blade, a blade for rotating the raw material around the shaft, A blade drive member which moves forward and backward at a predetermined interval to cut the raw material and moves along the guide rail in the axial direction by a predetermined width in a state in which the blade is backward; And it is achieved by the binding strap bundle manufacturing apparatus including a control unit for controlling the rotating means and the blade drive member.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a partially cutaway perspective view of an apparatus for manufacturing a bundle string according to a preferred embodiment of the present invention.

The binding strap bundle manufacturing apparatus of the present invention has a configuration capable of rotatably installing the raw material (5) wound around a shaft (3) on the base (1) wound around a wide plate-like material. This shaft 3 is rotatably comprised with the raw material 5 by the 1st motor 7. Of course, the change of the structure for rotating the raw material 5 can be made easy. In addition, the base 1 is rotatably provided with guide rails 8, 9 of the upper phase installed in parallel with the shaft 3. The guide rails 8, 9 are rotationally driven through the gears 12, 13, 14 coupled with the second motor 11 installed on one side. A spiral is formed on one of the guide rails 8 and 9 to engage with a tooth (not shown) formed on the bottom surface of the blade driving member 15, whereby the guide rails 8 and 9 are operated. In this rotation, the blade driving member 15 coupled thereto can be transferred in a desired lateral direction. Moreover, the bundle string manufacturing apparatus has the control part 17. As shown in FIG. The control unit 17 is a device capable of controlling the blade drive member 15, which is provided with a normal hydraulic pressure (not shown), by controlling the hydraulic pressure of the blade drive portion 19 of the blade drive member 15 before, Drive backwards. In addition, the control unit 17 controls the lateral movement of the blade drive member 15 by controlling the driving of the second motor 11 at a predetermined time interval. Reference numeral 21 is a blade that is rotationally driven.

FIG. 2 is a plan view of the blade driving member 15 of FIG. 1, wherein the blade driving portion 19 is fastened to a pair of slide grooves 23A and 23B formed on the blade driving member 15 and controlled by the controller 17. As shown in FIG. It has a configuration that is operated forward, backward along the slide groove by the hydraulic action through the cylinder 25. The cylinder 25 is fixed to the cylinder holder 27 and the blade drive unit 19. The blade drive unit 19 is provided with a third motor 29 therein, the drive shaft (not shown) of the third motor 29 and the rotary shaft 33 of the blade 21 is an electric belt 31. Connected by). The rotary shaft 33 of the blade is rotatably fixed to the pair of rotary shaft support intervals 35A and 35B.

3 is a right side view of FIG. 2, and FIG. 4 is a side view of the rotary blade of FIG. 3 moved to a position where the raw material is cut, and the same parts are denoted by the same reference numerals in order to avoid overlapping descriptions. The support guides 37 and 38 of the blade driving member 15 are movably coupled to the pair of guide rails 8 and 9. That is, the spiral guide is formed in the guide rail (9) is formed inside the support 38, the spiral is engaged with the spiral of the guide rail (9), the blade driving member due to the engaging operation when the guide rail (9) rotates 15 moves along the guide rail 9.

The operation and effects on the apparatus for manufacturing a tie string of the present invention configured as described above will be described in detail with reference to FIGS. 1 to 4.

The control unit 17 is preset with necessary data which enables the blade drive member 15, the first motor 7 and the second motor 11 to be driven. First, when the first motor 7 and the second motor 11 are driven by a signal from the controller 17, the raw material 5 rotates in the direction of the arrow due to the rotation of the shaft 3 and the blade drive. The member 15 rotates the guide rails 8, 9 due to the rotation of the guide rails 8, 9 by the engagement operation between the second motor 11 and the gears 12, 13, 14. Therefore, it is linearly moved to either end of the raw material 5 to be rotated. As the blade drive member 15 is linearly moved along the guide rails 8 and 9, the blade drive member 15 is guided by one of the guide rails 9 as shown in FIGS. 1 and 3 and 4. Is screwed together. When the blade drive member 15, which is linearly moved to one end of the rotating raw material 5, reaches the desired position of the raw material 5, the driving of the second motor 11 is stopped by the controller 17. Thus, there is no further movement of the blade drive member 15. Next, the blade 25 is continuously operated to allow the blade 21 to extend gradually toward the raw material 5, and the third motor 29 is operated to operate the blade 21 linked with the third motor 29 and the belt 31. Rotate (21) in the direction of the arrow. As soon as the blade 21 extended by the cylinder 25 is rotated and comes into contact with the raw material 5, the raw material 5 is easily cut by the sharp blade 21, and the cylinder 25 By continuous elongation of the blade), the blade 21 cuts the raw material 5 while entering the deep inside of the raw material 5, that is, adjacent to the shaft 3, as shown in FIG. When the blade 21 reaches a position adjacent to the shaft rod 3 that rotates the raw material 5, the blade 21 only rotates in a stopped state without further stretching due to the stopping of the stretching operation of the cylinder 25. . The cylinder 25 stops after being precisely stretched by the roll thickness t of the raw material 5 by the data previously input to the controller 17. Therefore, since the blade 21 also forms a state of exactly stopping in the adjacent position with the shaft 3, there is almost no damage due to the friction between the blade 21 and the shaft 3. Furthermore, as shown in FIG. 4 and FIG. 5, since the core 5a of the paper material is generally provided inside the raw material 5, the blade 21 is adjacent to the shaft 3 of the core 5a. Even if it stops after only positioning up to the site, the binding string bundle 39 can be easily separated in the state as shown in FIG. 5 due to the paper material of the core material 5a.

When the expansion operation of the cylinder 25 is stopped in the above, the control unit 17 causes the cylinder 25 to be retracted to its original position. When it is confirmed that the blade 21, which is rotated by the contracting operation of the cylinder 25, comes out of the raw material 5, stops the contracting operation of the cylinder 25 again and then drives the second motor 11 to drive the blade. The second motor 11 is stopped after the member 15 is moved by a predetermined width from the cutting position. In this state, when the cylinder 25 is stretched only to a predetermined position, the raw material 5 is cut by the blade 21 continuously rotating. By repeating this process, the raw material 5 is cut on the shaft 3 with a roll-shaped bundle 39 as shown in FIG. In the above embodiment, the cutting process of the raw material 5 has been described step by step, but this is only to help understanding of the present invention and may automate the entire process. In addition, since the control operation of the first to third motors 7, 11 and 29 and the cylinder 25 by the controller 17 may be variously modified, only one of the embodiments will be described in detail. Is omitted.

In addition, while the preferred embodiment of the present invention has been described above, a plurality of raw materials may be collectively processed by installing a plurality of blades and installing a plurality of raw materials at the same time. In addition, various modifications may be made to the driving means disclosed in the present invention without departing from the scope of the claims by those skilled in the art.

As described above, the binding strap bundle manufacturing apparatus according to the present invention has an excellent effect that the manufacturing cost is reduced as well as the manufacturing time is significantly reduced by manufacturing the bundle strap bundle with a simple fixing.
