Abstract

PROBLEM TO BE SOLVED: To prevent a tape from going backward as to a binding machine for gardening. SOLUTION: The tip end of a leaf spring 16 provided in a driver handle 2 is elastically contacted to the ceiling face near the front end of the handle. By forming the bottom end part of the front wall face of the handle as a tape pulling out opening 15, a tape comes out from the opening 15 downward curved sharply with the tip end of the spring 16 as a boundary. When the tape is pulled backward by a tape roll in a tape magazine turned in a reverse direction owing to a vibration, etc., the tape T is prevented from moving backward because the tape is curved sharply at the tip end of the spring 16 for upward pulling force to be applied to the spring 16 and for causing the tape T to be pressed against the ceiling face of the handle.

Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a tape guide device for a horticultural tying machine, and more particularly to a tape guiding device for a horticultural tying device that prevents tape from moving backward. It is about. 2. Description of the Related Art Cucumbers,
BACKGROUND ART In cultivation of agricultural products such as melons, grapes, and tomatoes, horticultural tying machines are used for tying vines and branches of these plants along pillars and shelves. The horticultural binding machine is a hand-held stapler-type tool combined with a driver handle and a clincher arm.A tape magazine is attached to the back of the driver handle, and the tape loaded in the tape magazine is pulled out at the tip of the driver handle. Pull out from mouth and use. [0003] When the driver handle and the clincher arm are closed once, the leading end of the tape is captured by a tape gripping device provided on the clincher arm. When the driver handle and the clincher arm are opened, the tape is moved between the driver handle and the clincher arm. Tape is stuck. And
When the tape is wrapped around the branch and the prop of the crop and the driver handle and clincher arm are closed with a stronger force than the last time, the overlapping portion of the tape wrapped around the branch etc. is bound by staples and at the same time the driver handle cutter is cut. The blade cuts the tape in the vicinity of the binding portion, and the tape loop wound around a branch or the like is cut off from the tape on the main body side. [0004] A gardening bundling machine is used in various postures for bundling agricultural products. At this time, the tape roll in the tape magazine may rotate in the reverse direction and the leading end of the tape may be pulled back. In this case, the tape gripping device on the clincher arm side may not catch the leading end of the tape on the driver handle side, and may fail in binding. In addition, there is a problem that it takes time to adjust the amount of pulling by pulling the leading end of the tape. . In the conventional horticultural binding machine, a leaf spring is arranged in a driver handle, the tape is pressed against a passage wall surface or a guide by the leaf spring, and tension is applied to the tape to prevent slack. The effect of the prevention is weak, and the tape often returns as described above. Therefore, there arises a technical problem to be solved in order to prevent the tape from moving backward, and an object of the present invention is to solve the above problem. SUMMARY OF THE INVENTION The present invention proposes to achieve the above object. A tape magazine is provided in a driver handle of a stapler, and a tape loaded in the tape magazine is inserted into the driver handle. A tape guide device in a horticultural binding machine that pulls out a tape by pulling out the tape by pulling out the tape by a tape gripping device provided on a clincher arm through a tape pull-out opening at a leading end, wherein a leaf spring is forwardly inserted in a driver handle. In a tape guide device of a gardening tying machine that applies tape to the inner wall surface of the driver handle by a leaf spring and applies tension to the tape by using a leaf spring, the tip of the leaf spring is positioned above or below the front end of the driver handle. While making elastic contact with the wall, the contact point of the leaf spring and the tape The tape guide device of the tying machine for horticulture is characterized in that the tape path is prevented from reversing by displacing the tape path at an acute angle by displacing the tape path. An embodiment of the present invention will be described below in detail with reference to the drawings. First, the overall configuration and operation of a horticultural binding machine will be described. FIG. 1 shows a gardening binding machine 1, in which a driver handle 2, a clincher arm 3, and a lower handle 4 are combined in a pliers shape, and a tape for gardening is loaded into a tape magazine 5 at the rear of the driver handle 2, and a driver is installed. Pull out the tape from the tip of the driver handle 2 through the inside of the handle 2. As shown in FIG. 2, a clincher 6 is attached to the tip of the clincher arm 3, and a picking plate 7 and a push plate 8 are provided slightly ahead of the clincher 6.
And a tape gripping device that combines a fixed cam plate (not shown) with a tape gripping device. Although illustration is omitted, the pin of the picking plate 7 is engaged with the groove cam of the push plate 8 slidable up and down and the groove cam of the fixed cam plate, and when the push plate 8 projecting upward by a spring is pressed down, By the cooperation of the groove cam of the push plate 8 and the groove cam of the fixed cam plate, the picking plate 7 is rotated to the near side, and the push plate 8 is locked at the pushed position. When the push plate 8 is further pushed in, the lock is released, and when the push plate is released, the push plate 8 returns to the initial position, and the picking plate 7
Rotates backward and returns to the initial position. In the binding operation, the upper and lower handles 2,
If the push plate 8 is pushed in one step by grasping and closing the pick 4, the picking plate 7 rotates to the near side, the wedge-shaped projection formed at the tip of the picking plate 7 pierces the tip of the tape, and the picking plate 7 and The front end of the tape is sandwiched by the fixed tape support plate 9. Then, once the handle operation is released and the upper and lower handles 2 and 4 are opened, the tip of the tape is pulled by the picking plate 7 and pulled out from the tip of the driver handle 2, and between the driver handle 2 and the clincher arm 3. The tape is put on. In this state, if a crop branch and a support are inserted between the driver handle 2 and the clincher arm 3, a tape loop is looped around the branch and the support (not shown). As shown in FIG. 3, when the upper and lower handles 2, 4 are closed to form a tape loop and the handles 2, 4 are further gripped, the staple driver 10 provided on the driver handle 2 is further lowered. And push out the staples (not shown) in the staple magazine.
Staples penetrating both ends of T loop are clincher 6
And the tape is bound, and the tapered cutter blade 12 pushes off the tape T near the binding location. The lock is released by pushing the push plate 8 deep, and when the upper and lower handles 2, 4 are returned to the initial positions, the picking plate 7 and the push plate 8 return to the initial positions shown in FIG. FIG. 4 shows the front part of the driver handle 2 and 13
Is a handle frame, and 14 is a handle cover. The handle cover 14 is attached to the handle frame 13, and a gap between the lower end of the front wall surface hanging down from the front end of the upper surface 14 a of the handle cover 14 and the lower surface 14 b is a tape outlet 15. The leaf spring 16 is located on the lower surface 14b of the handle cover 14.
However, the plate spring 16 may be directly attached to the handle frame 13 without providing the lower surface portion 14b, and the tape outlet 15 may be formed between the handle cover 14 and the handle frame 13. The distal end of the leaf spring 16 faces forward and upward, and is in elastic contact with the ceiling surface near the front wall surface of the handle cover 14. Tape T is attached to handle cover 14 by the end of leaf spring 16.
And is pulled out through the tape outlet 15. By causing the tip of the leaf spring 16 to resiliently contact the ceiling surface near the front end of the handle cover 14, the tape T bends sharply around the tip of the leaf spring 16 and exits from the tape outlet 15 below. I have. FIG. 5 shows a state when the tape T is pulled out. The leaf spring 16 is pushed down by the tape tension, and the tape T is pulled out from the tape pull-out opening 15. On the other hand, when the tape roll in the tape magazine 5 rotates in the reverse direction due to vibration or a change in the posture of the gardening bundling machine from the stop state in FIG. The tape is bent sharply downward from the tip of the
A force is applied to pull the tape 16 upward, and the tip of the leaf spring 16 presses the tape T against the ceiling surface of the handle cover 14. Also,
The pressure of the leaf spring 16 increases as the tension for pulling back the tape T increases, thereby preventing the tape T from moving backward. It should be noted that the present invention is not limited to the above-described embodiment, and various modifications are possible within the technical scope of the present invention, and it goes without saying that the present invention extends to those modifications. is there. As described above, in the tape guide device of the gardening bundling machine of the present invention, when a force for pulling the tape back to the tape roll is applied, the leaf spring presses the tape and moves backward. Since the configuration is such that the tape roll in the tape magazine rotates in the reverse direction due to vibration or the like, the leading end of the tape is not pulled back, and the possibility of unsuccessful binding is eliminated.
