Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a retrieval device comprising rolled strips of bag closure tags arranged side by side and joined at their short and narrow sides and serving to separate these tags. .

Plastic bag closure tags, like stamps, tickets, etc., are typically separated by tearing from a roll suspended for rotation about a horizontal axis.

The object underlying the invention is to enable the end of the bag to be closed to be quickly and precisely inserted into the opening of the bag closure tag, and then to tear or remove the tag from the strip of the bag closure tag. The bag 13 has an ejection device that allows it to be broken.
/l is provided for the same tag.

According to the invention, to achieve this objective, a retrieval device of the kind defined above is first proposed, which comprises a strip of bag closure tag with at least one vertical stop. and a groove extending forward from the end of the support plate for the passage of the bag closure tag strip, corresponding to the thickness of the bag closure tag strip. The width of the groove and its height are greater than the width of the strip of the bag closure tag. This passage groove can be linear, curved, spiral or twisted.

In the last mentioned case, it is also possible for the bag closure tag to emerge from the groove opening after being rotated, for example, 900 times on the strip of the bag closure tag.

The first bag closure tag of the bag closure tag strip is pulled forward enough from the tf'pWr groove to allow the end of the bag to be closed to move along the ramp and into the opening of the tag. It will be done. This operation can be facilitated by extending the groove and providing a rail with a stop at its end in the preferential development of the removal device according to the invasion. Since the distance between this stop and the end face of the groove wall is slightly greater than the length of the bag closure tag, the tag is free to tear or break.

Since the sloped surface of the f-claw in the groove is in such a positional relationship with the stop at the end of the rail, the sloped surface is in contact with the second bag-closing tag when the first bag-closing tag contacts the stop. It reaches the opening in the upper edge.

After the first bag-closing tag has been pulled away from or broken off from the bag-closing tag strip, the next most forward bag-closing tag is moved so that the end of the bag to be closed is aligned with the bag-closing tag along the sloped surface. It occupies a precise position where it can be moved into the opening in the upper edge of the.

When the bag is pulled, the strip of the bag closure tag moves to a stop at the end of the rail, and then, after the foremost bag closure tag is broken, the next tag takes its place and assumes the correct position for the insertion of the bag. . A notch at the outer end of the passage channel facilitates insertion of the bag neck.

To ensure that the strip of the bag closure tag is guided in the passage groove, a spacer element is inserted above the groove; this element shall be removable and Allows for replacement if the size changes.

According to the priority development of the extraction device according to the invention:
A support extending beyond the protrusion of the separation point is installed below the force support plate. This support serves to prevent the removal device from tipping over when the foremost bag closure tag is torn from the strip. However, if the support plate is fixed to the base (table), e.g. by screws, or, according to other preferred embodiments, is folded to the wall, e.g. by hinges, , this support is unnecessary.

An illustrative example of a removal device based on this innovation is shown in the drawing.

Identical parts are designated by the same reference numerals in different drawings.

The retrieval device includes a support plate carrying a strip of bag closure tag. In the embodiment shown in Figures 1N and 2, two vertical stop plates 3
, 4 are V@ on the edge of the support plate 1 to prevent the at strip 2 of the bag closure tag from slipping off the support plate 1.

Starting from the corner where the stop surfaces 3, 4 meet, the passage groove 5 extends outwardly as an extension of the stop surface 4 approximately tangentially to the rolled strip 2 of the bag closure tag. The tip of the strip 2 of the bag closure tag passes through a narrow passage channel. The groove 5 is surrounded by side walls 6, 7 whose spacing is slightly larger than the thickness of the strip 2 of the bag closure tag (1st-). The walls 6-7 terminate outside the inclined surface 8. The height h of the groove 5 is greater than the width 6 of the strip 2 of the bag closure tag. Therefore, the inclined surface 8 at the end of the passage groove 5 extends to a point higher than the height of the bag closure tag 9.

The end 10 of the bag 11 to be closed can move along this slope from top to bottom and automatically enters the opening in the upper edge of the bag closure tag 9 (FIG. 2). )
. The leading tag 9, together with the bag 11, is pulled along the rail 12 forming an extension of the groove 5 to the stop 13 at the end of the rail 12 and then torn from the strip 2 of the bag closing tag, or broken. The bag-closing tag 9, which has subsequently come forward, receives the end of the bag 10 guided along the inclined surface 8 in the central opening and assumes the correct position for further closing.

The groove 5 is closed at its top by a spacer element 14 which is removably inserted into the groove 5. If the size is changed, this spacer element 14
can be replaced.

A support 15 can be provided below the support plate 1 and furthermore has a protrusion at the tear point to prevent the device from falling over when the preceding bag closure tag 9 is torn from the 411 strip 2 of the bag closure tag. It should extend beyond and onto a horizontal surface.

In the embodiment shown in 3rd rW, the support plate 1 is circular and the groove 5 for ;m W, δ is curved. Therefore, regarding the separate strip 2 of the bag closure tag,
A single vertical stop surface 4 is practically sufficient.

FIG. 4 shows a take-out device a having a structure corresponding to that shown in FIG. and their respective final positions are indicated by dotted lines. For this purpose, the hinge 20 is fixed by one swivel plate on the horizontal arm of the plate 19 to be fixed to the wall 18 and another swivel plate on the support plate 1. In this way, the present extraction device can be installed at any location in a space-saving manner.

There is also a notch 21 to facilitate insertion of the neck 10 of the bag.
In FIG. 14 it can be seen at the front end of the walls 6, 7 of the passage groove 5.
