Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a stem and leaf binding machine for root vegetables, which bundles a desired number of root vegetables sent by a conveyor and wraps a binding string around the stems and leaves. This invention relates to an improved foliage holding device for bundling.

[Prior Art] The present applicant previously submitted a stem and leaf binding machine for root vegetables as Utility Application No. 1987-77592.

In this root vegetable tying machine, as shown in FIG. 4, the foliage 4 of the root vegetables placed on the conveying surface 3 is transferred to the tying area 7 by the moving projection 6. The stems and leaves 4 are compressed by the guide plate 8 and transferred to the binding section 19.

That is, since the lower surface of the guide plate 8 is inclined so that the distance between it and the conveying surface 3 becomes narrower from the leading end to the rear end, the stems and leaves 4 are transported along the lower surface of the guiding plate 8. Therefore, it is compressed so as to be pressed by the lower surface of this guide plate 8.

Then, the binding of the compressed foliage portion 4 is completed, and the compression force of the foliage portion 4 transferred backward from the guide plate 8 is released, and the binding becomes stable due to the expansion of the foliage portion 4.

[Problem to be solved by the invention] However, when the number of root vegetables to be bound decreases, or when the capacity decreases due to poor growth of the stems and leaves 4 of the root vegetables, the amount of compression by the guide plate 8 decreases. Therefore, the amount of expansion of the stems and leaves 4 transferred rearward from the guide plate 8 also decreases, the binding force decreases, and the binding becomes unstable.

In order to solve this problem, tension is applied to the moving binding string 24 by increasing the braking force of the braking device 29 to apply a load to the moving binding string 24, thereby compressing the insufficient amount of stems and leaves. 4 may be compressed and bundled.

The braking device 29, which has been widely used in the past, is provided near the string passage hole 31 of the storage box 30 that stores the binding string 24 provided on the frame 1. That is, the braking device 29, as shown in FIG.
A protruding rod 3 protruding outward from the side plate of the storage box 30
A spring 33 is interposed between the brake plates 2 and 2, and two brake plates 34 are provided so as to be expandable and retractable, and the binding cord 24 drawn out from the storage box 30 is passed between the brake plates 34, and the needle of the arm 35 is The portion 36 is inserted through the binding portion 19 and supported by the binding portion 19.

If this braking device 29 is not provided, when the binding is started and the arm 35 rotates, the binding string 29
is drawn out from the storage box 30, and the binding string 24
However, due to inertia, the length ends up being longer than necessary.
The binding string 24 is bent, and a phenomenon occurs in which the binding string 24 cannot be positioned at the predetermined position of the knot.

In this case, due to the above-mentioned phenomenon, a problem arises in which the knot is not tied even if the bundling means 5 operates, but the braking device 29 brakes the bundling string 24 to prevent the above-mentioned phenomenon from occurring.

However, when applying tension to the string 24 to compress the foliage part 4, the string 24 moves on the outer circumferential surface of the foliage part 4, reducing the volume. The problem of cutting or damaging the stems and leaves may occur, and although the initially desired binding force can be obtained, the binding force may be reduced due to cutting of the stems and leaves due to damage during transportation during post-work, or the quality may deteriorate due to damage to the stems and leaves. A problem arises.

The present invention was devised to solve these problems, and regardless of the volume of the stem and leaves, it can be used to securely bind the stems and leaves without cutting or damaging them with strings. It is an object of the present invention to provide a simple and novel stem and leaf pressing device for a root vegetable stem and leaf binding machine that can be used to bind roots.

[Means for Solving the Problems] In order to achieve the above object, the stem and leaf pressing device of the root vegetable tying machine of the present invention is supported by a frame, and the root vegetable is held perpendicular to the conveyance direction, and the stem and leaf portion are held on one side. A conveyor is provided in the middle of the conveyor for placing and conveying the stems and leaves extending from the side of the conveyor, and a binding string is attached from the front in the conveying direction of the stems and leaves to be conveyed by extending from the side of the conveyor. a tying means for feeding the root vegetables across the side and folding them back to tie them; The movable protrusions for aligning and pressing the foliage and the transport receiving plate surface of the frame are provided at an angle above the binding area where the binding means is provided, so that the distance between the movable protrusions and the conveying plate surface of the frame becomes narrower. A guide plate for guiding the string, and a removably installed guide plate facing the guide plate on the transport receiving plate surface of the frame below the binding area, in order to reduce friction of the binding string wound around the stem and leaves. It is equipped with an elastic auxiliary guide plate.

[Function] In the above configuration, even when the volume of the stems and leaves of root vegetables is small, the stems and leaves transferred to the binding area are held between the guide plate and the auxiliary guide plate and are supplied to the binding unit under a predetermined amount of compression. By simply wrapping the string around the outer circumferential surface of the compressed stems and leaves and tying them together, the intended binding force can be obtained.
