Description

[Detailed description of the invention] The present invention relates to a tag supply device for an automatic tying machine.

An automatic binding machine that wraps steel plate strips (hereinafter referred to as straps) around items to be bound and automatically binds them has a sealing machine that tightens the straps at their overlapped parts on a movable guide plate that guides the straps to the required position. It is composed of a binding mechanism.

In this automatic tying machine, a steel plate tag (hereinafter referred to as a tag) with the factory number and symbol stamped on it is installed in advance in the strap, and the strap is tightened over the object to be bound. ing. As shown in Fig. 2, the tag normally used with conventional binding machines has long holes 2a at both ends of a rectangular plate 4 for passing the strap 2 through, and the end including the hole is bent toward the object to be bound. It has a similar structure.

In order to incorporate this tag 4 into the strap 2, a magazine case is used in which the tags are stacked vertically and pushed out one by one from the side, and this is attached to the side of the strap passage route, while the tags are moved back and forth along the strap passage route. It was equipped with a cradle. The first drawback of such conventional devices is
After tying, the tag strongly presses the object to be bound at the edge of the steel plate, which is just the thickness of the steel plate, which damages the surface of the object. By mounting on the side, a movable tag holder must be provided for this purpose, which complicates the structure of the automatic tying machine. As a countermeasure for the first drawback, the inventor of the present application has provided a hole 5a at both ends of the flat plate 5 as shown in FIG. We created a prototype tag.

However, with this type of tag structure, the conventional magazine case that pushes out the tag from the side cannot be used as is. The present invention is intended to eliminate the drawbacks of the above-mentioned prior art,
The purpose is to provide a binding machine that can automatically supply a binding agent that does not damage the objects to be bound.

The structure of the invention disclosed in this application is as follows.

In other words, ``the present invention consists of a seal tightening mechanism that is installed along the path of passage of a strip for surrounding and binding objects to be bound, tightens the strip, and seals the strip at the overlapping portion; This invention relates to an automatic binding machine, which is equipped with a tag supply device installed adjacent to a fiber continuation mechanism and for attaching a tag to the strip in a part of the passage path of the strip. The magazine case has long notches on both sides for passing through the belt plate, and the outermost part of the hole is folded into a plano-convex shape to store multiple tags stacked vertically. A pair of locking mechanisms that move forward and backward to hold the lowest tag on both sides and allow it to escape downward;
and a movable guide plate having a swinging arm so as to move backward from that position, so that the tags are sequentially taken out from below without damaging the objects to be bound in the tag supply device and moved to the strip passing position. An automatic tying machine can be provided that can be brought to the site and installed on the strip.

Hereinafter, the contents of the present invention will be explained in detail according to preferred embodiments. FIG. 4 shows the entirety of an automatic tying machine equipped with a tag feeding device according to the present invention.

In the same figure, ``7 is the sealing and tightening mechanism which is the main body of the binding machine;
7a is a seal storage box, 6 is a tag supply device, and these are connected along the passage route of the strap 2 shown by the dashed line. 8 is a strap guide plate, which is a seal tightening mechanism. 7, it is moved back from the position shown in the figure by swinging on the lower surface side in a direction perpendicular to the strap passing direction.

A magazine case 9 of the tag supply device 6 is installed above the strap passage path where the tag is supported by the guide plate 8. FIG. 5 is a sectional view of the tag supply device taken along the row 0'' direction of FIG. 4.

In the figure, reference numeral 9 denotes a magazine case in which the tags 5 shown in FIG. 3 are stored vertically stacked with the plano-convex surface 5b facing down. At this time, a certain amount of gap d is created between the stacked tag plates. The bottom tag 5A of the stacked tags has two pairs of claws, that is, upper claws 10, that protrude inward from the window holes 9a on both sides of the magazine case 9.
, 10 and the lower claws 11, 11. These claws are air cylinders 12 and 13 that operate on the upper and lower sides, respectively.
It is attached to the tip of the magazine case and moves forward and backward into the magazine case. Reference numeral 8 denotes a strub guide plate, which is attached to the arm 8a and is attached to the seal tightening mechanism as described above, and is driven by the motor 7b and oscillates 1800 degrees around the axis 0 in the figure, as indicated by the two-dot chain line in the figure. It is designed to retreat to position 8' as shown.

Next, the tag supplying operation by the above tag supplying device will be explained.

The lower claws 11, 11 move forward in the magazine case 9, and the upper claw 10 moves forward.
9 With 10 in retreat, stack the tags on top of the 1,1 stove. Next, after advancing the upper claws 10, 10, the lower claw 1
1. When the holder I is moved backward, one of the tags 5A at the bottom naturally falls onto the strap guide plate 8 at the strap passing position, and the other tag is still supported by the upper claw 10 and the holder 01. In this state, the strap 2 coming out of the sealing tightening mechanism 7 passes through the hole 5a of the tag 58 on the guide plate 8 and passes around the object 3 to be tied through the strap chute 14 as shown in FIG. The strap guide plate 8 moves counterclockwise as indicated by the arrow x, encircling the object to be bound, and overlaps the binding material twice at the bottom of the woven cotton width 7. During this time, the strap guide plate 8 on the lower side
is closed and guides the strap at the bottom of the sealing and tightening mechanism 7. Next, the strap guide plate 8 is swung by the power of the motor and retreated to the position shown by the two-dot chain line (Fig. 5, 8'), and in this state, the seal tensioning mechanism lowers and moves the strap in the opposite direction (clockwise). ), and when the upper surface of the object to be bound is reached, a clamp claw (not shown) on the side of the sealing loom operates to perform sealing.

FIG. 1 shows a state in which the objects 3 to be bound have been bound with the tie 1 attached to a part of the strap 2.

As described in the embodiments above, all the objects of the present invention are achieved and the following effects are obtained.

{1} By using a tag bent in a plano-convex shape, it is possible to obtain objects to be bound that will not be damaged by tags.

- By moving the upper and lower claws forward and backward, the tag supply device can take out tags stacked one above the other from below, bring them to the strap passing position, and attach them to the strap.

{3} Since the swinging strap guide plate provided in the seal tensioning mechanism can be used as is, and there is no need to provide a strap holder, the structure of the automatic strapping machine including the strap supply device can be simplified. Moreover, since no extra space is required for the tag holder, the device becomes compact and the manufacturing cost can be reduced. The invention is not limited to the above embodiments.

For example, the strap guide plate may be of a type that does not swing but slides in the horizontal direction. As a means for moving the upper and lower claws of the tag supply device forward and backward, a linkage mechanism, an electromagnetic solenoid, a motor drive, etc. may be used.
