Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a taping machine for binding articles with tape.

(Prior art) As this type of tape hanging machine, for example,
-36560. In this tape hanging machine, an item is fed onto a table so as to feed the tape against the tape stretched between the tip of a tape hanging arm and a tape presser, and then the item is attached to the item by lowering the tip of the arm. In the conventional device shown in the above-mentioned publication, in particular, as shown in FIG. Although the reel e is rotated to rewind the tape, a tape tension adjustment device is not provided.

(Problem to be solved by the invention) In this type of tape hanging machine, it is important to apply a certain tension to the tape before wrapping it, and for this reason a spring is installed inside the reel that supports the tape. Although this method prevents the tape from being unrolled excessively due to excessive rotation of the reel, there is a problem in that it is not possible to apply appropriate tension to the tape when the reel is operated rapidly.

An object of the present invention is to provide a tape hanging machine that can always apply a predetermined tension to the tape during banding, and can therefore perform banding with an appropriate tension applied to the tape.

(Means for Solving the Problems) The tape hanging machine according to the present invention is characterized by a tape hanging arm having a plate spring 18 that pinches and contacts the tape with one of the guide rollers 15 provided on the arm. and an adjustment mechanism 19 for adjusting the contact of the leaf spring with the guide roller.

(Operation of the above means) By sandwiching the tape between the guide roller 15 and the leaf spring 18, tension can be applied to the tape in an adjustable manner. Note that the support rod 7 of the tape guide roller 7a is
The downward pivoting of the tape prevents excessive tension from being applied to the tape, and the support rod 7 absorbs slack in the tape.

(Embodiment) Figures 1 to 3 show the entire embodiment of the tape hanging machine according to the present invention, in which 1 is a base, 2 is a table on which the article A to be bound is placed; , a support 3 is provided near the table 2. Arm 1 for hanging tape on post 3
The arm 10 is preferably a generally U-shaped member having a crimp portion 1 at its distal end.
1 and a cutter 12 are installed, and furthermore, a handle 13 for operation and a member 14 for supporting a reel 4 storing tape are installed at appropriate positions. On the table 2, there are a crimping table 21 and a tape presser 22 at a position corresponding to the tip of the arm 10. In this embodiment, a transverse member 5 extending rearward from the column 3 and a column 3 are provided.
There is a member 6 extending upwardly along the axis, the upper end of the member 6 being provided with a stop member, preferably a roller 6a. Further, a support rod 7 is pivotally fixed to the support member 14 of the reel 4, and a tape guiding roller 7a is supported at the tip of the support rod 7. and support rod 7
The right-angled portion 7b at the pivot end of the cross member 5
There is a spring 8 between the end of the cross member 5 and a spring 9 between the end of the cross member 5 and a suitable position on the arm 10.

Furthermore, guide rollers 15, 16, and 17 for guiding the tape are installed at appropriate positions on the arm 10.

As shown in the figure, the present invention is characterized by a plate spring 18 that pinches and contacts the tape T with one of the guide rollers, in the illustrated example, the guide roller 15, in order to apply an appropriate tension to the tape during banding. A mechanism 19 is provided for adjusting the contact, that is, the pressing force, of the leaf spring 18 with respect to the guide roller 15, and the adjustment mechanism preferably consists of an adjusting screw 19a and a female screw 19b as shown in the figure. In that case, the tip of the adjustment screw is in contact with the leaf spring 18. In this way, with a simple structure,
Adjustment is possible with simple operations. In addition, leaf spring 1
In the case of the illustrated embodiment, it is preferable to use the guide roller 15 between the reel 4 and the roller 7a at the tip of the support rod 7 as the guide roller that is contacted by the roller 8.

During operation, the item A is fed into a predetermined position on the table 2 by applying it to the tape T loosely stretched between the tip of the arm 10 and the tape presser 22 below, and then the arm 10 is pivoted downward by the handle 13. The tape is then wrapped around the item by lowering the tip of the arm.
In the process of feeding the article onto the table 2, the tape is unwound from the reel 4, passes between the guide roller 15 and the leaf spring 18, and passes through the roller 7a.
It is guided by guide rollers 16 and 17 and is let out from the tip of the arm 10. At this time, since the tape is held between the guide roller 15 and the leaf spring 18, back tension acts on the tape, thereby applying tension to the tape. Further, when the tape is wound around the entire circumference of the article by lowering the arm 10, the tape is also unwound and tension is similarly applied. The tension of the tape is increased by strongly pressing the guide roller 15 with the plate spring 18 and weakened by the adjustment screw 19a.

When the tip of the arm 10 reaches the lowest position, the crimping unit 11 abuts against the crimping table 21 with the tape in between, crimps or welds the tapes together, and then cuts the tape with the cutter 12. , complete the taping. Next, as the arm 10 rises, the cutter 12 moves away from the crimping table 21, and at the same time the tape presser 22 presses the new end of the tape and returns to its initial state. Note that the arm may be operated automatically using a cylinder device or the like. Further, in this embodiment, the leaf spring 18 is in contact with the guide roller 15 between the reel 4 and the roller 7a, so that even if the arm 10 is lowered, the support rod 7 is held in place by the spring 8 as shown in FIG.
When the arm 10 rises, the support rod 7 is held down by the roller 6a of the member 6, keeping the tape in a slack state, as shown in FIG. Therefore, in this case, when the item is fed onto the table 2, the tape is unwound from the reel and tension is applied after the tape has no slack. In the structure of this embodiment, when the arm 10 is rapidly lowered and excessive tension is applied to the tape, the support rod 7 pivots downward to relieve the tension on the tape, which has the advantage of avoiding breakage of the tape. .

In the above embodiment, the tension of the tape is adjusted using an adjustment screw, but the guide roller 1
5 can be pressed by the leaf spring 18 by another mechanism. For example, as shown in FIG. 5, the wedge body 19c may be moved by a screw 20.

Alternatively, it is possible to use a cam 19d as shown in FIG. 6, or any other suitable mechanism can be used.

(Effects of the invention) Therefore, according to the invention, it is only necessary to absorb the slack of the tape after the guide roller that the leaf spring 18 comes into contact with at the time of banding, and as a result, the reel rotates too much due to inertia and the imaginary line in FIG. Even if there is excess slack as shown, it only occurs between the reel and the guide roller at the leaf spring position, and has no relation to the tension of the tape used for banding. Therefore,
Tension can be applied to the tape at all times during banding. With conventional products, all tape slack after the reel must be absorbed during banding.
If the reel becomes too slack due to excessive rotation, no tension is applied to the tape, but the present invention does not have such drawbacks, and even if the reel rotates too much, the tape can be wrapped with appropriate tension applied. can.
