Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a simple binding machine used to bundle stick-like objects such as vegetables, metal materials, or wood with adhesive tape.

(Prior Art) Recently, many vegetables such as spinach bound with adhesive tape are on the market, but when they are used, they are usually separated into individual pieces by tearing or cutting the adhesive tape. Ru. However, this type of adhesive tape cannot be easily cut by simply pulling it by hand, so a knife is usually used to cut it.

In order to solve this inconvenience, there are adhesive tapes in which the adhesive tape itself is treated to make it easier to tear, but this has the drawback of high manufacturing costs.

In addition, in a binding device that has a binding arm that can be tilted freely and a holder that holds the end of the tape, and that binds objects by tilting the binding arm, the binding arm may be knurled, etc. A device has already been proposed in which a pair of rolled rolls is provided, and the tape stretched over the binding arm is always held between the pair of rolls, thereby pre-damaging the tape to be wound and bound. However, in this type of binding device, the tape stretched on the binding arm is
The tape moves from the tape reel toward the tip of the binding arm, and during binding, moves in the opposite direction due to the action of back tension, and ends up reciprocating between the rolls, so the tape is moved by the rolls. You will be hurt twice. However, when binding objects to be bound, a considerable amount of tension is applied to the tape, resulting in the problem that the tape may break during binding in some cases.

(Problems to be solved by the invention) As mentioned above, in the conventional example described above, the tape itself is treated to make it easier to tear, but the cost is high, and a pair of rolls are used in the binding arm. However, there remains a problem in that the tape is excessively damaged and may not be able to withstand the tension during binding. In view of these problems, the present invention aims to make it possible to easily tear the tape after binding and to make it possible to damage the tape to the extent that it can withstand the tension exerted during winding and binding. .

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a tape binding device in which a cutting blade for cutting the tape is provided on a base on which a tape reel is rotatably held. A pair of rolls that hold the adhesive tape are provided between the reel and the cutting blade, and a scratch section is provided on the entire circumferential surface of one of the rolls to scratch the adhesive tape without penetrating the tape along its longitudinal direction. In addition, one roll can be freely moved toward and away from the other smooth roll, thereby making it possible to adjust the depth of scratches.

(Function) After the adhesive tape is pulled out from the tape reel and the tape is held by the cutting/scratching means, the tape is further pulled out and the end thereof is held by the cutting blade in preparation for winding and binding of the objects to be bound. When winding and tying, grasp the end of the tape and pull it out to extend it outward from the cutting blade for the required length. Then, apply the object to be bound to the extended part, and then pull the end of the tape. After wrapping the tape around the object to be bound by folding back the tape, the end of the tape is adhered to the tape between the cutting blade and the object to be bound, and the adhesive part is pressed against the cutting blade. Then the winding and binding is completed, and the adhesive tape is scratched along its length by a pair of rolls by grasping its end and pulling it out from the tape reel. Since the tape is wound and bound around the object to be bound, the tape can be easily removed from the object by tearing the tape.

Furthermore, since one roll can move toward and away from the other roll, the depth of the scratches on the tape can be adjusted by adjusting the pressure force between the rolls.

(Embodiments) The present invention will be described below with reference to embodiments shown in the drawings. As shown in FIG. 1, the base 1 includes a pair of support plates 1a, 1 arranged at a predetermined distance
a, and bottom plates 1b, 1b extending outward from the bottoms of the support plates 1a, 1a.
A cutting blade 2 for cutting the tape is attached to the upper part of the front end of the support plate 1a so as to cross the gap between the support plates 1a, 1a.
At the rear end, a rotating shaft 3 is rotatably attached to the supporting plates 1a, 1a at a predetermined distance from the cutting blade 2 so as to cross the gap between the supporting plates 1a, 1a. A tape reel 4 is removably attached to the shaft 3.

A frame 5 is provided between the cutting blade 2 and the tape reel 4. This frame body 5 has side plates 5a, 5a that are in contact with the inner surfaces of both support plates 1a, 1a.
and a horizontal plate 5b that crosses the gap between both support plates 1a, 1a.
The horizontal plate 5b is connected to the rear end portions of the side plates 5a, 5a, that is, the side plates 5a, 5a and the horizontal plate 5b are formed in a U-shape in cross section.

As shown in FIG. 2, a fixed shaft 6 that crosses the gap between the side plates 5a, 5a is provided at the upper part of the side plates 5a, 5a.
is attached to the shaft 6, and a guide roll 7 is attached to the shaft 6.
is rotatably mounted.

Furthermore, a second fixed shaft 8 is attached to the side plates 5a, 5a at a predetermined distance from the fixed shaft 6, and a holding roll 9 is rotatably attached to the fixed shaft 8. .

Further, a third fixed shaft 1 is provided on the side plates 5a, 5a.
0 is attached to the fixed shaft 10, and one end of a swinging member 11 is swingably attached to the fixed shaft 10.
The swinging member 11 includes a pair of holding plates 11a, 11a arranged at a predetermined interval, and the holding plate 11.
and a mounting plate 11b that connects the side plates 5a, 11a to each other, and the holding plates 11a, 11a are connected to the side plates 5a, 5
a, and the mounting plate 11b is arranged so as to cross the gap between the side plates 5a, 5a, that is, the holding plates 11a, 11a and the mounting plate 11b
It has a U-shaped cross section. The holding plate 1
A fixing pin 12 is attached to each of 1a and 11a at a predetermined distance from the third fixed shaft 10 and on the front side of the fixed shaft 10, and a scratching roll 13 is attached to the fixed pin 12. It can be installed freely.

The scratching roll 13 is used to damage the adhesive tape T in cooperation with the holding roll 9, as will be described later.For this purpose, the scratching roll 13 has a shape shown in FIGS. 3a to 3d on its surface. A scratched portion 13a is formed. In Figures a to c, a large number of small grooves are carved, and in Figure d, a large number of small protrusions are formed. As shown in the figure, this scratched portion 13a may be provided on both ends of the scratched roll 13, or may be provided only on one side end, or may be formed by a narrow notch or a protrusion with an extremely small diameter. If necessary, it may be provided over the entire surface of the scratching roll 13.
In these cases, the scratching roll 13 and the holding roll 9 are made of metal such as steel, iron, or aluminum, or hard resin such as plastic.

In addition to the above, a needle roll having a large number of short needles may be used as the scratching roll 13, and in this case, a rubber roll is used as the holding roll 9.

Furthermore, the scratching roll 13 may be a grinding wheel having abrasive grains on its outer circumferential surface, or a paper surface or a thin metal plate with abrasive grains attached to the surface, such as sandpaper, may be pasted on the outer peripheral surface of the roll. It can be anything.

The distribution density of the notches or small protrusions in the scratched portion 13a is appropriately selected depending on the type, thickness, etc. of the base material of the adhesive tape T (resin such as polypropylene, polyethylene, vinyl chloride, etc.).

As shown in FIG. 4, a screw hole is formed at the lower end of the mounting plate 11b of the swinging member 11, and an adjustment screw 14 is screwed into the screw hole. A stopper 15 is fixed to the tip. One end of a spring 16 is fixed to the stopper 15, and the other end of a spring 16 is attached to the lower end of the horizontal plate 5b of the frame 5 via a metal fitting 15'.

Next, to describe the operation of the binding machine having the above configuration, first, the tape T pulled out from the tape reel 4 is wound around the upper surface of the guide roll 7, and then passed between the holding roll 9 and the scratching roll 13, and the end of the tape T is wound around the upper surface of the guide roll 7. part is held by the cutting blade 2. To pass the tape T between both rolls 9 and 13, push the lower end of the swinging member 11 counterclockwise and move the member 11 onto the fixing pin 1.
2, the scratching roll 13 is moved counterclockwise, and the holding roll 9
The scratching roll 13 is kept separated from the. The swinging member 11 is elastically biased clockwise by the spring 16 attached in a compressed state, so when no external force is applied, the scratching roll 13
is pressed against the holding roll 9 as also shown in FIG.

This pressing force affects the depth of the scratches made on the tape T, so appropriate adjustment is required. This adjustment is performed by advancing and retracting the adjusting screw 14. In other words, when the screw 14 is screwed forward, the spring 16 is further compressed, and therefore the springing force is further increased, so the swinging member 11 swings clockwise, and the scratching roll 13 moves clockwise, so the pressing force increases. On the contrary, when the adjustment screw 14 is screwed back, the urging force of the spring 16 becomes weaker, so that the pressing force decreases.

After adjusting the pressure contact force of the scratching roll 13 in this way, the tape T held on the cutting blade 2
Pull out the tape T by holding the end of the tape T, wrap the tape T around an object (not shown), and then stick the end of the tape T to the part of the tape T extending from both rolls 9 and 13. The adhesive part is pressed against the cutting blade 2 and cut. This completes the winding and binding of the tape. To remove the tape that has been wound and bound around the object in this way from the object, grasp any two parts of the wound tape and pull it in opposite directions, or pull it in the width direction of the tape. Just tear it apart.

By the way, the above-mentioned holding roll is covered with adhesive tape T.
Since the adhesive side of the tape T is applied, the tape T will be adhered to the same roll 9, and the tape T
Since the tape T is once wrapped around the guide roll 7 and then wrapped around the holding roll 9, the adhesion length of the tape T to the holding roll 9 can be increased, and meandering of the tape T is therefore prevented. As a result, the tape T is prevented from deviating from the scratched portion 13a of the scratching roll 13.
will be accurately damaged. Further, as clearly shown in FIG. 2, a large-diameter collar 7a is usually formed at both ends of the guide roll 7 to prevent the tape from meandering. Since it is mostly prevented by adhesion to 9,
The diameter of the flange 7a can be made smaller, and compactness can be achieved.

Furthermore, as mentioned above, since the spring 16 is attached to the lower end of the swinging member 11, the tape T
Even if there is a thickness or thickness, the distance between the holding roll 9 and the scratching roll 13 will be maintained at the set value,
Therefore, the depth of the scratches made on the tape T is kept constant.

In the above, a scratching roll is used as the tape scratching means, but a roll having an endless band movably attached to the roll having a scratched portion having the shape described above on the surface may also be used.

Further, as shown in FIG. 5, in the above description, the length of the scratching roll 13 in the axial direction is approximately equal to the interval between the holding plates 11a, 11a of the swinging member 11, but as shown in FIG. 13 does not need to be provided over the entire length of the holding roll 9 in the axial direction, and may be provided so as to be able to contact only one end, the center, or both ends of the holding roll 9, as shown in FIG.

(Effects) As is clear from the above, the present invention is equipped with a pair of rolls that have scratched parts, so the tape with scratches is wound around and bound around the objects to be bound, resulting in damage. This means that the bound tape can be easily torn without using a knife or the like.

Furthermore, since one roll can move toward and away from the other roll, the depth of the scratches made on the tape can be adjusted as desired.

Furthermore, since scratches on the tape do not penetrate the tape,
To prevent the tape from breaking even if considerable tension is applied to the tape during winding and binding.
