Abstract

(57) [Summary] [Purpose] To prevent a string from slipping off from a string brake during tying operation, due to excessive feeding of the string on the upper side of the string brake in the string feeding direction, in a tying device. [Structure] Between the string outlet 8 of the string storage container 7 and the string brake 9, the plates 10 and 11 for forming the string brake 9 are installed.
A string regulating member 17 is provided outside the string insertion/removal port 14 to receive and prevent the drawn string from bending and protruding.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a string supply structure for a tying device used in a reaping and tying machine, etc. A rolled string is stored in a storage container, and a string handle is formed on one side of the storage container. The string is configured to be drawn out of the container from the outlet, and the string is removed from the outlet. A string brake is installed at a predetermined distance from the side of the container at an outer position, and this string brake It is made up of a pair of plates that are slidably inserted into the rod and supported and pressed together. The present invention relates to a string supply structure for a binding device.

0002

[Conventional technology]

In the string supply structure of the above-mentioned binding device, conventionally, for example, As shown in Publication No. 0, there is a new cable between the string outlet and the string brake. A work space for attaching the standard winding cord and passing the feeding cord through the cord brake. There is a structure in which only the bracket for supporting the string brake exists in this space. It had become.

0003

[Problem that the idea aims to solve]

The above string brake is used because the string is paid out at high speed due to the tying operation of the tying device. Therefore, at the end of the tying operation, the string is unwound from the winding string excessively due to inertia and hangs down for a long time. This is to prevent the cord from falling, but it is placed on the lower side of the string brake than the string brake. Although it is possible to prevent the string from being excessively drawn out when the string is placed in the Since there is no brake function between It may bend and protrude significantly outward. At this time, the string is inserted into the string brake. When the next binding operation is performed with the exit bent and protruding outward, the string brake will The string on the upper side of the drawer is in a position that protrudes outward from the string insertion/removal opening, allowing for high-speed pulling. There was a risk that the string would come off the string brake due to the pulling out.

0004 The present invention aims to eliminate such problems.

[0005]

[Means to solve the problem]

A characteristic configuration of the present invention is that in the string supply structure of the binding device described at the beginning, the string Between the take-out port and the string brake, the outer part of the string insertion/removal port of each of the plates is A string regulating member is provided at the location to catch and prevent the drawn string from bending and protruding. The point is that

[0006]

[Effect]

Due to the inertia of the string due to the high-speed string withdrawal associated with the tying operation, the string removal port and the string brake, the string is connected to the string insertion/removal opening of each plate in the string brake. Even if you try to bend and protrude outward, the string will be caught by the string regulating member and the string will be too large. prevent it from protruding too much. Moreover, the string regulating member is located on the outside of the string insertion/removal opening of each of the plates. There is a working space for threading the string on the left and right sides of this string regulating member. We can secure enough.

[0007]

[Effect of the idea]

Therefore, by rationally arranging simple structural members, the string can be pulled out from the string brake. This eliminates the inconvenience of the bundling operation being hindered due to it coming loose, and maintains smooth bundling operation. It became something I could hold.

[0008]

【Example】

Examples will be described below based on the drawings. FIG. 1 shows a waste straw tying device in a harvesting and tying machine. This binding device The waste straw that is successively raked in by the pick-up packer 1 is received and collected, and a predetermined amount is collected. Each time the string 3 is wound and fed by the needle 2, the string 3 is knotted at the knotted portion 4. After that, the bundled bundles of waste straw are discharged outside the machine. Said needle 2 The binding string 3 supplied by is stored in the storage container 6 in the string storage section 5. The winding cord 7 is wound in a roll-like manner and is sequentially let out.

[0009] The binding string 3 is inserted into the string outlet 8 formed in the string storage container 6 from inside the winding string 7. The cord is supplied to the needle 2 through the cord outlet 8, and A string brake 9 is disposed at a predetermined distance from the side surface 6a of the container. Figure 2, fig. As shown in FIG. 3, this string brake 9 is fixed to the side surface 6a of the container and connected to the string outlet 8. A plate-shaped brake body 10 extending from the center to a position at a predetermined interval [an example of a plate material] A plate-shaped brake plate 11 that overlaps the brake body 10 [another example of plate material] The brake body 10 and the brake plate 11 can be freely slid onto the rod 12. The string 3 is inserted and supported, pressed and biased by the coil spring 13, and the string 3 is pressed and clamped to perform the binding operation. It is configured to prevent the string 3 from being excessively fed out due to inertia accompanying the movement. A predetermined interval is provided between the string outlet 8 and the string brake 9 as described above. To facilitate the work of passing the string 3 through the string brake 9 when a new winding string 7 is installed. A working space has been created. Also, at a location near the string insertion/removal port 14 of the brake body 10. A protrusion 15 is formed toward the brake plate 11 side, and the above-mentioned portion of the brake plate 11 is An engagement hole 16 into which the protrusion 15 fits is formed at a location corresponding to the protrusion 15 to prevent pressure. In the connected state, the string 3 is prevented from coming off from the string insertion/removal port 14.

0010 Between the string outlet 8 and the string brake 9, a string insertion/removal port 1 is provided. 4 has a strip-like shape that catches and prevents the drawn string 3 from bending and protruding. A string regulating member 17 is provided. In other words, the string regulating member 17 is located at the upper end of the container side surface 6a. It is connected and fixed to the brake body 10 from the upper end of the side surface 6a of the container. The contact point against the brake body 10 is provided with the protrusion for preventing the brake from coming off. It is configured to be located closer to the rod 12 than the raised part 15. In this way, the string 3 is paid out at high speed with the binding operation, and the string brake 9 Due to the inertia of the string 3, the string brake 9 is pulled out of the string insertion/removal port 14 between the string outlet 8 and the string outlet 8. It can prevent the bending and protruding greatly towards the other side, and the next time the binding is activated. It is possible to effectively prevent the string 3 from coming off from the string insertion/removal port 14 of the string brake 9. It turns out.
