Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a binding machine suitable for use in gathering together a large number of elongated bodies, such as green onions, beef leaves, etc., and tightly binding them together using an adhesive tape.

Conventionally, a common method for collecting and binding a large number of long objects of this type is to apply a pressure-sensitive adhesive tape to an arbitrary location in a direction intersecting the longitudinal direction of the collected objects. A method has been used in which the material is wound with the adhesive layer on the inside, and the starting end of the winding and the back end of the winding are overlapped and bonded and bound.

However, the back side of the end of the bundle bound in this way is usually treated with peeling, so it is extremely easy to turn over, and a strong binding cannot be obtained. This tendency was strong in unity.

The present invention has been made for the purpose of solving the drawbacks of the conventional bundling body as mentioned above and providing a tying machine that can obtain a bundling body that is easy to unpack. A supply device, a winding device for winding adhesive tape around objects to be bound, a binding device for joining adhesive surfaces of the wound adhesive tapes to bind objects to be bound, and a plurality of adhesive tape holding surfaces. The holding block, which is a regular polygonal prism that holds the front and rear ends of the adhesive tape and has a flat spring pressed against one holding surface, can rotate only in the direction opposite to the winding direction of the adhesive tape. , a holding device connected to the link mechanism via a roller clutch mechanism or a ratchet mechanism, a suppressing device capable of sticking the rear end of the adhesive tape to the holding surface of the holding block opposite to the rear end, and the adhesive tape. an adhesive tape cutting device capable of cutting the rear end of the wound adhesive tape so as to separate from the wound adhesive tape and remain on the holding block; the other end of the link mechanism is connected to a winding device; The binding machine is characterized in that the holding block rotates when the adhesive tape is rotated in a direction opposite to the winding direction of the adhesive tape, and the holding block does not rotate when the adhesive tape is rotated in the winding direction.

An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a pedestal, and columns 2, 2 whose upper portions are bent in the horizontal direction are erected at both ends of one side of the pedestal 1, and between the tips of the horizontal parts of the columns 2, 2. A support plate 3 is suspended from the support plate 3, and an adhesive tape winding body 4 is rotatably attached to the left side of the support plate 3 in FIG. A supply installation 7 is constituted by a tension adjustment mechanism 6 formed by an arm and a roller at the tip of the arm, and the adhesive tape 4 is pulled out so that its back surface is in contact with the roller of the tension adjustment mechanism 6. It is led out to a holding block via a spreading roller.

8 is a winding lever, which is fixed to one end of the rotating shaft 22;
As shown in FIG. 2, an output shaft 11,
The adhesive is rotated in the direction of arrow A via the arm 12 and pin 13, and is stretched onto the objects to be bound placed on the support stand 15 by the stretching roller 14 provided at the tip of the winding lever 8. It functions to wind the tape 4, and after winding, it is rotated in the direction of arrow A' by the tension spring 16 and restored to its original position, thus forming a winding device 17.

Reference numeral 18 denotes a holding block made of a regular triangular prism, which has three adhesive tape holding surfaces, and is fixed to a rotating shaft 20 attached to bearings 19, 19.

Therefore, the holding block 18 is operated in conjunction with the operation of the winding lever 8, and the rotating shaft 20 is provided with a rotating shaft 20 that rotates only in the opposite direction to the winding direction of the adhesive tape 4, that is, in the clockwise direction in FIG. An arm 23 in which a roller clutch 21 that rotates idly in the counterclockwise direction is fixed,
On the other hand, an arm 24 is fixed to the other end of the rotating shaft 22 to which the winding lever 8 is fixed.
A connecting arm 25 is connected between these arms 22 and 4.
A link mechanism 26 is formed by 24 and 25, and when the winding lever 8 is rotated in the direction of arrow A by the rotary solenoid 10, the arm 23 is rotated around the rotation axis 20. However, since the rotational resistance of the roller clutch 21 may cause the rotating shaft 20 to rotate together, one holding surface of the holding block 18 is shaped like a plate. The rotation is stopped by pressing with a spring 21.

Then, when the winding lever 8 is rotated in the direction of arrow A' by the spring 16 and restored, the arm 23 is rotated clockwise by the roller clutch 21 via the link mechanism 26, and the holding block is also rotated. 18 rotates in the same direction while pushing down the plate spring 27.

At this time, the rotation angle is 120 degrees due to one movement of the winding lever 8 in the direction of arrow A', and thus the holding block 18
, rotation shaft 20, roller clutch 21, link mechanism 26
A holding device 28 is constituted by the plate spring 27 and the plate spring 27 .

Reference numeral 29 denotes a binding lever, which is rotatable in the direction of arrow B by a row solenoid 31 having a rotation shaft 30 mounted on the right side opposite to the adhesive tape winding body 4;

A binding block 35 is vertically disposed on the slide shaft 33 so as to be slidable on the slide shaft 33.

Free rollers 36 and 37 are provided at the tip of the binding block 35.
, 38, 39 are attached.

As shown in FIG. 2, the binding lever 29 has an arm 44 fixed to the output shaft 40 of the low pressure solenoid 31 and an arm 45 rotatable on the support plate 3 connected by a pin 46, and 45 is fixed to the binding lever 29, the rotary solenoid 31 and the binding lever 29 are interlocked. On the other hand, when the rotary solenoid 31 is not activated, the tension spring 56 causes the binding lever 29 to move in the direction of arrow B. It is rotated in the ' direction and restored to its original position.

Therefore, when the binding block 35 rotates in the direction of arrow B, the free rollers 38 and 39 press the adhesive tape against the stopper 47 attached under the support base 15, and the adhesive tape is wound. The adhesive surfaces of the tapes are joined together to bind objects to be bound, and a binding lever 29, a low resolenoid 31, a binding block 35, a free roller 38.
39 and the stopper 47 constitute a binding device 48.

Further, due to the rotation of the binding block 35, the free rollers 36, 37 press the rear end of the adhesive tape against the holding surface of the holding block 18, which corresponds to the left slope in FIG.

The pressing device 49 is thus configured.

A cutting blade 50 is fixed to the slide shaft 33 and moved in and out of the binding block 35 by sliding the binding block 35 by a compression spring 34, thus forming a cutting device 51.

Next, as shown in FIG. 4, the compression spring 34 is compressed by the restraining operation of the binding block 35, and the cutting blade 50 attached to the slide shaft 33 is projected, and the rear end of the adhesive tape is wound It is cut to separate it from the adhesive tape, and the front end of the adhesive tape is pressed and peeled off from the holding block 18.

The rear end of the adhesive tape thus becomes a bale that remains on the holding block 18.

Next, when the object to be bound P is moved in the direction of the arrow and rotated counterclockwise, the rear end of the adhesive tape bends the rear end of the adhesive tape, and the lower layer of the adhesive tape is bent, as shown in FIG. When a binding body in the form of a binding body is obtained and the completion of binding is confirmed by a signal (not shown), the binding lever 29 is first rotated in the direction of arrow B' by the tension spring 46. The winding lever 8 returns to its original position, and then the winding lever 8 is rotated in the direction of arrow A' by the tension spring 16, and the link mechanism 2
6, the rotation shaft 20 is also rotated clockwise, and the holding block 18 is also rotated 120 degrees in the direction of arrow C, and the state before binding is restored and the cycle is completed.

By repeating this series of operations, a large number of bundles can be made continuously.

The long bodies to be bound by the binding machine of the present invention include green onions,
In addition to vegetables such as natural vegetables, products that are relatively lightweight and long, such as straw-shaped chopsticks, toothpicks, and pencils, and are sold in large numbers can be cited as targets.

The adhesive tape front and rear end holding device used in the device of the present invention has a flat holding surface to which the adhesive tape can be stuck, and the holding surface corresponds to the front and rear ends of the adhesive tape. Although the shape is not particularly limited as long as it has a direction, a regular polygonal column shape as in the above embodiment is preferably used.

Mechanisms that can rotate only in one direction include a rotary clutch mechanism and a ratchet mechanism.

In the above embodiment of the device of the present invention, an example was shown in which the binding device, the pressing device, and the cutting device were integrated into the binding lever and the binding block. It may also be operated by an independent mechanism.
