Description

[Detailed Description of the Invention] This invention relates to a tape tying machine used for tying the insertion opening of bags or attaching display labels to rod-shaped bodies such as round or square bodies.

Various binding machines for this purpose have been proposed in the past, but
These methods have a simple structure, but because the materials to be bound are cut horizontally, there are problems in that they cannot be applied to objects with large bulges at both ends of the materials to be bound, or to endless objects.

This idea was made to solve the above-mentioned shortcomings of the conventional binding machine.The device was designed to solve the above-mentioned drawbacks of the conventional binding machine. By inserting the material and pressing the material to be bound onto the bottom of this recess and rotating the main frame downward, the tape is wrapped around the material to be bound and both ends are affixed, making it possible to cut the tape. The purpose of the present invention is to provide a tying machine that can simultaneously perform tape wrapping and take out the material to be bound upward after wrapping the tape.

Next, the details will be explained based on the attached drawings.

Reference numerals 17 and 18 refer to front and rear links whose lower ends are pivotally attached to the front and back of the middle of the main frame 2. is fixed so that the head 20 moves in and out of the recess 6 as the links 17 and 18 swing, and the lower tip of the head 20 is shaped like an arc, so that the cutter 15 is inserted from the lower tip. A groove 21 into which the cutting edge fits is provided.

Further, the lower end of the swinging rod 22, whose upper end is pivoted to the end of a piece projecting rearward and downward from the pivot joint at the lower end of the link 17, is pivoted to the upper support piece of the base plate 1, so that the main frame 2 When the link 17 is rotated downward, the link 17 is configured to rotate forward, and a spring 23 is installed between the ring 18 at the rear and the main frame 2 to pull the link 18 rearward, and the spring 23 is attached to the rear of the link 17 at the front. A stopper 24 that limits the rotational position of the main frame 2 is fixed to the main frame 2.

Reference numeral 25 denotes a tape holding lever whose lower end is pivotally connected to the rear end of the board 1 by the shaft 3, and this lever 25 and the link 1
8 are connected by a connecting rod 26.

This lever 25 consists of a pair of left and right levers, and the shaft of the tape winding frame 27 is removably engaged with the notch at the upper end of the lever 25.
The adhesive tape 28 wound around 7 is guided to the upper side of the feeding head 20 with the adhesive side facing upward.

A check roller 29 having a check pawl and a ratchet wheel is provided near the upper rear end of the main frame 2, and a guide roller 30 that presses the tape 28 against this roller 29 is pivoted to the main frame 2 to move the tape 28 forward. should move, but not backwards.

Additionally, a tape pressing device A is provided near the front end of the upper part of the main frame 2.

This device A includes a swinging frame 32 whose rear end is pivotally connected to the main frame 2 by a shaft 31, and a plate spring pivoted to the same shaft 31 so as to be swingable.
It consists of a spring 34 that is attached between the rear end of the leaf spring 33 and the swing frame 32 to apply rotational force to the leaf spring 33.

The binding machine of this invention has the above structure, and FIG. 1 shows the state before operation, at which time the front link 17 hits the stopper 24 by the action of the spring 23, and the swinging rod 22 connected to the link 17
The main frame 2 is held in the upper position by the action of .

At this time, the advancing/retracting rod 19 is in the retracted position, and the feeding head 2
0 is retracted to the rear of the recess 6, and the tip of the adhesive chip 128 that is fed out from the winding frame 27, passes between the rollers 29 and 30, and passes through the swing frame 32 of the tape holding device A and the leaf spring 33 is retracted into the recess. 6 and reaches the cutter 15.

In this state, when the material to be bound B is inserted into the one-housing recess 6 placed on the tape 28 above the recess 6, this tape 28 bends into the recess 6 as shown in FIG. It is attached to the bottom of B.

After the material to be bound B with the chi 128 attached to the lower part hits the support 7, when the material to be bound B is further pushed down, the main frame 2 rotates downward about the shaft 3.

When the main frame 2 rotates downward, a forward rotational force is applied to the link 17 by the action of the swinging rod 22, and the advancing/retracting rod 19 moves forward.
The head 20 at the front end advances onto the material B to be bound in the recess 6, and the tip of the head 20 pushes the tape 28 from above the head 20 toward the bottom of the material B to be bound, causing the material B to be bound to become Wrap the chi 128 from the side to the top.

As the head 20 moves further forward, the cutter 15 is inserted into the groove 21.
The cutting edge penetrates and cuts the tape 28.

The end A of the cut tape 28 on the side of the material to be bound B is the tape 28 pushed into the notch 16 of the cutter mount 14.
It is attached to the tip of the

At this time, the main frame 2 hits the stopper 5 as shown in FIG. 2, so when the material to be bound B is released from the press, the main frame 2
The material to be bound is taken out from the recess 6 as each part returns to its original position and becomes the state shown in FIG.

In the above operation, when the main frame 2 rotates downward and the feeding head 20 moves forward, the link mechanism causes the tape holding lever 25 to rotate forward, so that the resistance to feeding the tape 28 is alleviated.

When the head 20 moves back, the lever 25 also moves back, but since the tape 28 is prevented from moving back by the check roller 29, the tape 28 is fed out from the tape reel 27.
Since the leading end of the tape 28 is placed on the cutter 15, the next binding operation can be performed immediately.

As mentioned above, the present invention is pivotally mounted on the board and can be bound with an extremely simple operation of inserting the objects to be bound into the recess at the upper front of the frame and rotating the main frame downward. However, since the series of operations such as feeding, pasting, and cutting the tape by moving the tape feeding head back and forth is automatically performed by a link mechanism, no power such as an electric motor is required.

Further, since the moving distance of the material to be bound is short and the material to be bound can be pulled out in the same direction as the insertion direction, it is easy to take it in and out of the recess of the main frame.

Furthermore, since the recess is equipped with an adjustable support and a guide member, it has the advantage of being able to adjust the size of the recess according to the size of the material to be bound, and the tape holding lever is linked to the feeding head. Because it moves, there is less resistance when applying the tape,
Adhesion of the tape can be done easily even by manual operation.
