Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tape folding device in a device for binding seaweed bundles with tape.

[Prior art] When binding an appropriate number of folded seaweed bundles with paper tape, wrap the seaweed bundles around, overlap both ends of the tape, and bend the tape at right angles at a 45° crease. The wrapped tape is folded in parallel and passed between the wrapped tape and the seaweed to form a single knot, and the remaining tape end is used to form a double knot.

For this purpose, in order to first bend the overlapped tape ends in the right angle direction, place the overlapped tape ends on a folding seat with a 45° step, press the tape against the step using the bending guide to create a crease, and then Press the top of the tape from the direction (JP-A-63-167889), or fold the tape by rotating the tape clamping piece inserted from the 45° direction by 180° (JP-A-63-232117) ) is used.

[Problems to be Solved by the Invention] In such conventional folding devices, the operation for folding the tape in the right angle direction is complicated;
In addition to raising and lowering the folding seat for folding, the folding guide and pressing pieces must be moved back and forth from both sides, and the clamping pieces must be rotated, which is not only cumbersome, but also requires the use of tape to attach the folding device to the machine base. Since it is installed on both sides or diagonally, there are problems such as the installation space becomes large.

The present invention allows for easy operation and a compact device.

[Means for solving the problem] For this purpose, a holding frame that reciprocates in the width direction of the tape on the front surface of the backing plate, a holding plate that protrudes from this holding frame and has a tip formed at a 45° angle, and this holding plate are provided. The inserter is provided with a bending operation plate whose tip is bent in a 45° direction so as to face the holding frame, and an opening/closing mechanism that opens and closes the interval between the holding plate and the bending operation plate, and which reciprocates independently of the holding frame. The plate is provided on the holding plate side of the holding frame so that it can be raised and folded together with the holding frame, and after the holding plate and the bending operation plate sandwich the end of the tape and closing, the bending operation plate is placed on the bending part of the holding plate. I try to move it in a direction that covers the tip.

[Function] Therefore, when the holding frame is folded down and the space between the holding plate and the bending operation plate is opened and the holding frame is moved forward, the holding frame is overlapped from the bottom between the tip of the holding plate and the bent part of the bending operation plate. When the end of the tape is inserted and the holding plate and bending plate are closed in this state, the tape end is pinched and the bending part of the bending plate pushes up the tape, bending it at a 45° crease along the tip of the holding plate. It will be done. After that, when the bent part of the bending operation plate moves toward the holding plate so as to cover the tip of the holding plate, the tape end is folded down within the bent part along the tip of the holding plate, and is perpendicular to the holding plate and the insertion plate. It can be bent in the direction.

The tape end bent in this way is folded over the insertion plate, so when the holding frame and insertion plate are raised vertically, the tape end bent at right angles will cross in front of the insertion plate. In this state, the end of the tape is pushed by the forward movement of the insertion plate, and is inserted between the tape and the seaweed bundle through the back side of the winding guide.

Next, the operation will be explained.

The lever 12 moves the sliding plate 11 to open the opening 9.
The seaweed bundle 4 is held by the backing plate 2 and the pressing plate 3 while the tape is being blocked, and when the tape is fed into the guide groove 5 and the tip of the tape operates the tape end detector 10, the wrapping device 6 As a result, the rear end of the tape is wrapped around in front of the opening 9, and the winding guide 8 descends to press the front surface of the tape. The front end of the tape in the guide groove is pushed up and overlapped with the rear end of the tape coming out of the winding guide 8 to form the tape end 7a.

When the holding frame 15 is tilted horizontally by the operation lever 33 and the operation ring 29 moves to the right by the operation of the operation lever 31, the operation rod 22 is moved through the operation piece 30.
moves to the right, and the stopper 28 is pushed by the spring 32, causing the spline shaft 14 to move to the right until it hits the support seat 27. Therefore, the holding frame 15 and the operating rod 22 move simultaneously, and the tape end 7a is moved from FIG. is inserted.

When the operating ring 29 moves further, the operating piece 30 compresses the spring 32, causing only the operating rod 22 to move to the right, and the tip of the operating rod 22 pushes out the tapered piece 21 via the spring 23, as shown in Figure 5c. Close the gap between the presser plate 16 and the bending operation plate 19 to sandwich the tape end 7a, and also close the bending part 1 of the bending operation plate.
9 pushes up the tape end 7a and bends it upward at an angle of 45 degrees along the tip of the presser plate 16. At this time, the pin 40 of the operating rod 22 moves within the elongated hole 45 shown in FIG. 3, and the lever 44 does not operate.

When the operating ring 29 moves further to the right, the tapered piece 2
Since the pin 1 cannot be moved due to engagement with the holding piece and the bending operation plate, the operation rod 22 moves the pin 26 within the elongated hole 25 and moves the pin 40 to the right while compressing the spring 23. Therefore, the pin 40 in contact with the right end of the elongated hole 45 of the lever 44
is pressed, the lever 46 is pulled via the lever 43, the pin 42 is moved to the left along the elongated hole 47 of the holding frame, and the bending operation plate 17 is pulled back. By this movement of the operation plate, the bent part 19 covers the tip of the presser plate 16 as shown in FIG.
At 9, it is pressed against the holding plate 16 side, bent at a right angle, and stacked on the holding plate 16.

When the tape end 7a is bent, the spline shaft 14 is rotated via the operating lever 33, the holding frame 15 is raised together with the insertion plate 34, and the tape end is bent so that the width direction thereof is perpendicular. (Figure 5e).

The operation lever 36 moves the operation ring 35 to the spline shaft 3.
5 to the right, the insertion plate 34 pushes the bent tape end 7a into the back side of the winding guide 8.

As the insertion plate pushes the end of the tape,
When the operating ring 29 is moved to the left with the operating lever 31 and the operating rod 22 is pulled back, the pin 40 pulls back the lever 44 and moves the pin 42 of the lever 46 to the right in the elongated hole 47, pushing out the bending operating plate 17.
As the operation rod retreats, the pin 26 pulls back the tapered piece 21 and presses the holding plate 16 and bending operation plate 17.
is opened, and the holding frame 15 is moved to the left via the spline shaft 14 (FIG. 5f).

When the insertion plate 34 is pushed into the tape end 7a, a single knot is formed, but the tape end 7a is held by the leaf spring 37 and the insertion plate 34 is pulled back. Next, when the deflection device 38 is operated, the tape end 7a held by the leaf spring 37 is removed from the leaf spring 37 by the upright pin 39, is folded back to cover the bent part on the front surface of the winding guide 8, and is folded back again. The tape end 7a is inserted into the back side of the winding guide 8 using the insertion plate 34 (FIG. 5g) to form a double knot.

When the insertion plate 34 is pulled back by the operation ring 35, the operation ends in the state shown in FIG. 5h.

[Effects of the Invention] As described above, the present invention provides a binding machine for binding seaweed bundles with tape, which includes a holding frame that reciprocates in the width direction of the tape in front of the backing plate, and a holding frame that protrudes from the holding frame so that the tip thereof is bent at an angle of 45 degrees. a bending operation plate that faces the presser plate and has a bent portion in a 45° direction with its tip bent toward the presser plate, and an opening/closing mechanism that opens and closes the presser plate and the bending operation plate, An insertion plate that reciprocates separately from the holding frame is provided on the holding plate side of the holding frame so as to be raised and folded together with the holding frame, and after the holding plate and the bending operation plate are closed with the end of the tape between them, the bending operation plate is inserted. Since the insertion plate is configured so that it moves to a position where it covers the tip of the presser plate at the bent part, the insertion plate can be integrated with the holding frame equipped with the presser plate and the bending operation plate, and the end of the tape can be moved in the right angle direction. Since the bending operation can be performed by reciprocating the holding frame, opening and closing the holding plate and bending operation plate, and the bending part, the device can be configured compactly, the installation space can be reduced, and the bending operation can be performed reliably. The bent end of the tape is bent over the presser plate and the insertion plate, making it easier to insert the end of the tape.
