Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a pedestal for a binding machine.

[Conventional technology]

Wrap the tape around the items to be bound that are placed on the pedestal,
There are known binding machines in which one end of the tape is held by a tape holding device, the other end is guided to a binding arm, and the binding arm is moved up and down relative to the tape holding device to adhere and cut the tape (for example, ,
(Japanese Patent Application Laid-open No. 57-125107), it is often used for binding vegetables, etc.

[The problem that the idea attempts to solve]

By the way, when the objects to be bound need to be made into a large bundle, the objects cannot be placed on the pedestal all at once, so it is done in several batches. For this reason, the mounting operation takes time, and during this time the tape stretched under the objects to be bound on the pedestal becomes slack, making it impossible to obtain tight binding. That is, even if the tape is loosened before binding and is attempted to be tightened at the time of binding, the weight of the object to be bound on the pedestal is too heavy and the resistance is too strong, resulting in the disadvantage that the tape cannot be tightened sufficiently.

[Means to solve the problem]

Therefore, in this invention, a tape is wound in a loop around an object to be bound placed on a pedestal, one end of the tape is held by a tape holding device, and the other end is guided to a binding arm to perform the binding. In a binding machine that binds the objects to be bound by sliding the tape loop on the pedestal and tightening it as the arm descends, the tape is placed on the top surface of the pedestal in parallel to the direction in which the tape extends. By providing a cradle for a binding machine characterized by providing a protrusion having a chevron-shaped cross section and having a height slightly larger than the thickness of the tape and a gap slightly wider than the width of the tape. The problem was solved.

[Effect]

This creates a gap between the items to be bound and the tape, reducing the weight of the items on the tape, allowing the tape to slide easily during binding.
It will be a tight bond.

[Example] Hereinafter, an example of this invention will be described with reference to the drawings.

Figure 1 is a plan view of the binding machine, Figure 2 is a front view, Figure 3 is a partially sectional front view showing how the tape is bonded and cut, Figure 4 is a cross-sectional view of the pedestal, and Figure 5 is a front view of the binding machine.
The figure is also a longitudinal sectional view.

The binding machine consists of a binding arm 1, a tape holding device 2, etc., and the binding arm 1 holds a wound tape 3.
The tape is fed out from behind, guided by a binding arm 1, and one end of which is held by a tape holding device 2. On the other hand, between the binding arm 1 and the tape holding device 2, a pedestal 5 is set on which objects to be bound 4 are placed. With this configuration, when the object to be bound 4 is inserted from the outside of the tape 3 onto the pedestal 5 and the switch is turned on, the binding arm 1 descends to the tape holding device 2 and adheres and cuts the tape 3 as follows. Do it.

That is, the tip of the binding arm 1 is equipped with a press body 6, a pusher 7, a cutter 8, and a guide roller 9 from the inside, and the tape holding device 2 is also equipped with a press body 6 corresponding to the press body 6 from the inside. A press stand 10, a hole 11, a fixed clamp 12 and a movable clamp 13 are installed at the position. Furthermore, one end of the tape 3 is held between the fixed clamping body 12 and the movable clamping body 13, and the other end is guided to the guide roller 9 with the other end half wrapped around the object 4, so that the binding arm 1 When the tape 3 is lowered, the press body 6 overlaps the tape 3 in two sheets, and the guide roller 9 hits the movable clamping body 13 and moves it backward. Therefore, the tape 3 is bonded between the press body 6 and the press stand 10 (because adhesive is applied to the polymerized inner surface), and the pusher 7 pushes the polymerized tape 3 into the hole 11. A tension force is applied to the upper tape 3, and the lower tape 3 is peeled off from the movable clamping body 13. In this state, when the binding arm 1 continues to descend, the cutter 8 descends due to the relative movement of the press body 6 with respect to the binding arm 1 and cuts the upper tape 3. As the tape 3 rises, the cut end of the tape 3 is again held between the movable holding member 13 and the stationary holding member 12.

Next, the area around the pedestal 5 is configured as follows.

That is, the pedestal 5 is composed of a lower pedestal 14 and an upper pedestal 15, of which the lower pedestal 14
is the set screw 17 for the case 16 of the binding arm 1.
It is fixed by etc.

The upper pedestal 15 is fitted and fixed onto the upper surface of the lower pedestal 14 from above. In addition, inside the lower pedestal 14, there is a rotator 1 which can be rotated downward while being urged upward by a spring 18.
9, a plate 20 projects laterally (forward) from the rotator 19, and a push plate 21 is fixed to the end of the plate 20. A switch 22 (for starting the motor) is provided to detect the inclination of the rotator 19 due to the depression of the plate 20.

By the way, in this invention, on the upper surface of the upper pedestal 15 constituting the top surface of the pedestal 5, two tapes having a chevron-shaped cross section and having a height slightly larger than the thickness of the tape 3 are placed in a direction parallel to the direction in which the tape 3 extends. Projections 23, 23
is formed, and furthermore, this protrusion 2
3 and 23 are installed at an interval slightly wider than the width of the tape 3. As a result, when the objects 4 to be bound are placed, a gap is created between the upper surface of the pedestal 5 and the objects 4 to be bound where the tape 3 passes, and it may take time to place the objects 4 to be bound. , or even when the objects 4 to be bound are placed on the pedestal 5 in several parts, the tape 3 does not slacken.
It will be stretched with appropriate tension. Further, during binding, the tape 3 slides on the object to be bound 4 in order to tighten the object to be bound, and at this time as well, the presence of the above-mentioned gap allows for good sliding. Note that since the tape 3 used is very thin (about 0.05 mm), the height of the protrusions 23, 23 may be small. That is, the height of the protrusions 23, 23 is small, and the width is only slightly wider than the width of the tape 3, and the cross section is chevron-shaped. It occupies a small area, and its presence means that there is no need to worry about the posture of the object 4 changing when placed on it.

[Effect of idea]

As described above, in this invention, the pedestal 5 in contact with the object 4 to be bound
Two protrusions 2 are provided on the top surface parallel to the stretching direction of the tape 3.
3 and 23, the resistance of the tape 3 from the objects 4 etc. to be bound is reduced even when the tape 3 is tensed during adhesion, and the tape 3 slides sufficiently and a tight binding is achieved. It can be done. In this case, the height of the protrusions 23, 23 is small,
The width is a little wider than the width of the tape 3, and the cross section is chevron-shaped, so the object to be bound 4 can be wrapped around the protrusions 23, 23.
Since it is floating with only a small gap between the parts and the other parts are in good contact with the pedestal 5, changes in posture and damage are less likely to occur.

Furthermore, since the adhesive (glue) side of the tape 3 is on the top surface, floating the object 4 by the height of the protrusions 23, 23 means that the adhesive surface and the object 4 do not come into contact with each other as much as possible. , to ensure more slippery.

Furthermore, since the tape 3 extends between the protrusions 23, 23, this becomes the target binding position, and advantages such as being able to always bind at a constant position can be expected.
