Abstract

PURPOSE: To reliably hold a tape without relying on an adhesive or the like by a method wherein objects to be bundled are bound by a tape, the tape is adhered and cut, the just cut tape is held by a tape push receiver and a rear cape holder, and thereafter it is held by a front tape holder and the rear tape holder. CONSTITUTION: A tape 10 is fed out from a drum along a binding arm 16, its end is held on a tape table 18, and objects to be bundled 22 are mounted onto a binding table 20 to push the tape 10 from the front. The binding arm 16 is vertically moved to make the tape table 18 close and distant, and the tape 10 is wound around the objects 22, adhered and cut by a cutter 42. The just cut tape 10 is held by a tape push receiver 38 and a rear tape holder 40, and it is securely held by a front tape holder 36 and the rear tape holder 40 thereafter. Thus since the tape 10 is held without relying or an adhesive, the tape can be reliably held.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape binding machine for binding vegetables and the like using a reel tape.

[0002]

2. Description of the Related Art The present applicant first unwinds a reeled tape and holds it on a tape stand via a binding arm that moves up and down, and moves the binding arm up and down to bring it into contact with and separate from the tape stand. Various tape tying machines have been proposed for tying the objects to be bound with a tape, adhering and cutting them (for example, Jikken Sho 63-
No. 30648).

[0003]

However, the above-mentioned proposal has a structure in which, when the ends of the cut tape are held on the tape base, they are temporarily held by the adhesive of the tape. Also, the cutter had a structure in which it was attached to the binding arm downward. For this reason, when the adhesive of the tape is soiled with mud or the like, the initial holding force cannot be exerted and a binding error occurs. In particular, when binding vegetables, the tape is often soiled with mud or the like, which often causes this situation.

If the cutter is attached to the binding arm side, the operator may not see the cutter directly,
You may inadvertently insert your hands under the binding arm,
Sometimes I hurt my hand. The present invention solves these problems at the same time.

[0005]

Under the above problems, according to the present invention, a reeled tape is unwound and held on a tape stand via a binding arm that moves up and down, and the binding arm is moved up and down to form a tape stand. In a tape tying machine that binds and binds the objects to be bound by adhering and separating them with a tape, a tape retainer that presses the tape against the tape stand on the tying arm side, and a tape retainer that is provided in front of the tape retainer. Before and after the tape is pushed down from the table, and before and after the tape is pressed down, the tape guide rollers for guiding the tape are attached, respectively, and at the tape table side,
A cutter installed upward before and after the tape is pressed down to cut the tape before and after the tape is pressed down, and a cutter that is installed in front of the cutter and below the tape before it is pressed down. Provided below the tape guide roller and the tape push-down receiver that descends before lowering to allow advance after pinching the tape and rises before climbing tape to regulate forward after pinching the tape, It is provided below the tape guide roller guide, which rotates downward when the tape guide roller descends to advance the tape sandwiching front, and rotates upward when the tape guide roller rises to retract the tape sandwiching front, and below the tape guide roller guide. , The tape guide roller guide moves downward to release the holding of the tape end after the tape is sandwiched, and the tape guide roller guide rotates upward to retract to hold the tape end after the tape is sandwiched. It is provided before the tape is sandwiched for the purpose of holding it, and between the tape before the tape is sandwiched and the cutter. It moves forward when the tape push-down receiver descends and pinches the tape end with the tape push-down receiver, and moves backward when the tape push-down receiver rises. A tape tying machine is provided which has a tape before clipping and a tape after pinching the end of the tape.

[0006]

With the above-described means of the present invention, the tape immediately after cutting is sandwiched between the tape push-down receiver and after the tape is sandwiched, and then before and after the tape is sandwiched. Therefore, since the tape is not held by an adhesive or the like, the tape is held reliably. Further, the cutter is provided on the tape table so that the operator can see it. Therefore, it is safe without putting hands etc. on the cutter.

FIG. 1 is a sectional side view showing the details of the bundling arm 16 and the tape base 18. At the lower end (tip) of the bundling arm 10, a tape guide roller 24, a tape push-down front 26, and After the tape is pushed down 28 and a tape retainer 30 are provided respectively. Of these, the tape guide roller 24 and the tape front and rear 26, 28 are fixed to the bundling arm 16, but only the tape retainer 30 can move up and down with respect to the bundling arm 16, and It is urged downward by the spring 32.

On the other hand, on the tape base 18 side, a tape guide roller guide 34 is provided below the tape guide roller 24, and a tape nipping front 36 is provided below the tape guide roller guide 34.
A tape push-down receiver 38 is provided below the tape push-down 26.
In the tape push-down receiver 38, a tape 40 after the tape is caught behind the tape before the tape 36, and a front 40 after the tape is pressed,
Cutters 42 are provided behind the tape sandwiching 40, respectively.

The tape guide roller guide 34 has a rotation fulcrum 44 in front of the tape sandwiching 36, and the tape guide roller 24 rolls on the upper surface thereof (vertical movement of the bundling arm 16) so that the tape guide roller 24 can be vertically rotated. It has become. The tape sandwiching front 36 is also rotatable around a lower rotation fulcrum 46. The tape guide roller guide 34 is urged upward by a spring 48, so that the tape 3
6 is also biased rearward by a spring 50.

FIG. 2 is a front view of a main portion of the tape push-down receiver 38. The tape push-down receiver 38 is designed so that it can be moved up and down by guiding the vertical column 52, and after the tape is sandwiched 40, the tape is pressed from below. In addition to having a notch space through which a tape can be inserted, a window through which the tape sandwiching front 36 can enter is formed on the front surface. Further, a pin 54 is laterally provided in the tape push-down receiver 38, and restricts the forward movement of the tape after pinching 40. The tape push-down receiver 38 is biased upward by a spring 56.

Further, the after-tapping 40 of the tape and the before-tapping 36 of the tape are urged to approach each other by a spring 58. The cutter 42 is attached after the tape is sandwiched 40 with the blade surface facing upward, and the blade surface is formed obliquely and is set at substantially the same height as the tape base 18.

Next, the operation of the tape binding machine having the above construction will be described. When binding the objects to be bound 22,
The binding arm 16 is set to the highest position so that the tape 10 is stretched between the tape guide roller 24 and the tape base 18, and the binding target 22 is pushed from the front to push the tape 10 forward. Place it on top. Then
The tape 10 is slightly unwound from the drum 12 and is bound to
In this state, the binding arm 16 is lowered (the drum 12 is forcibly rotated in the opposite direction to narrow the loop of the tape 10) in this state. In this state, the end of the tape 10 is firmly sandwiched between the tape sandwiching portion 36 and the tape sandwiching portion 40 as described later.

FIG. 1 is a side sectional view showing the moment when the bundling arm 16 descends and the tape guide roller 24 comes into contact with the tape guide roller guide 34. The tape guide roller guide 34 rotates downward. The inclination of the top rolling surface of the tape guide roller guide 34 is different between the upper and lower sides, and the tape guide roller 24 moves from the upper rolling surface 34 a to the lower rolling surface 34.
At the time of moving to b, the downward rotation of the tape guide roller guide 34 is restricted, and this time, the tape sandwiching front 36 is moved forward (forward rotation around the rotation fulcrum 46).

FIG. 3 is a side cross-sectional view showing this state. In this state, the holding of the end of the tape 10 by the tape sandwiching 40 is released, but the tape base 18 of the tape 10 by the tape retainer 30 is released. Pressing against is maintained. At the same time, before and after the tape is pressed down, both the rear 26 and the rear 28 are lowered to lower the toe pressing receiver 38, and the front and rear of the cutter 42 of the tape 10 are strongly pressed downward to cut the tape 10.

FIG. 4 shows that the binding arm 16 is further changed from the above state.
Is a side cross-sectional view of a state where the tape is lowered, and in this state, the tape push-down receiver 38 is further lowered, and accordingly, the pin 54 moves below the tape-holding portion 40, and the tape-holding portion 40 is moved by the spring 58. It moves forward (rotates forward around the rotation fulcrum 46). Then 40 after the tape is sandwiched
Holds the end of the tape 10 remaining after being cut with the tape before pressing 2 so as not to come off.

From this state, the bundling arm 16 rises, but when the pin 54 of the tape push-down receiver 38 rises and retracts the tape after pinching 40 (release of holding of the tape 10), the tape before pinching 36 also simultaneously. As the tape 10 moves backward, the end of the tape 10 will be sandwiched by the tape sandwiching front 36 (the timing of this takeover is set instantaneously). Then, the binding arm 16 returns to the highest position and waits for the next binding.

[0019]

As described above, according to the present invention, the tape immediately after cutting is sandwiched between the tape push-down receiver and after the tape is sandwiched, and after that, the tape is sandwiched before and after the tape is sandwiched.
Therefore, since the tape is not held by an adhesive or the like, the tape is held reliably. The cutter is also provided on the tape table, which is visible to the operator. Therefore,
It is safe without putting hands etc. on the cutter.
