CZ20033336A3 - Device for withdrawing flat, hose-like, straight packages from a storage container and subsequent opening thereof - Google Patents

Abstract

In the present invention, there is disclosed a device for withdrawing flat, hose-like, straight packages (O) from a storage container (6) and subsequent opening thereof wherein the device consists of two parts (2, 3) provided with air bleeds (4) connected to a vacuum source. The upper part (2) is adjustable between the storage container (6) and the lower part (3) from above.

Description

Technical field

The invention is an apparatus for removing flat tubular line packages from a container and subsequently opening them.

BACKGROUND OF THE INVENTION

The packaging of the goods in line segments, i.e. in advance for the final length of the cut packages, is carried out manually. The operation, which considerably lengthens the packaging process, is to open the flat tubular segment. Such a package is in the form of a flat hose, the opposing walls of which are electrostatically adjacent to one another with respect to the material used, or the cut edges are joined together already during cutting by the heat generated.

The packaging of the goods into the tubular packaging is therefore carried out by machine into a continuous hose strip which is unwound from the disc magazine and after partial packaging the used part with the packed goods is separated in such a way as to guarantee accessibility of the opening in the continuous hose strip. The sensitivity of this operation makes such devices malfunctioning. For this reason, in other devices, the tubing is formed immediately prior to packaging. A flat strip is unwound from the disc magazine, which is welded longitudinally, thereby allowing the resulting tubular package to be filled from above.

None of the machinery is suitable for wrapping rods of constant length in packages of constant length, where the package is a carrier of information which must be completely on the package only once. For goods where there is no such requirement, the information on the packaging is shorter. ’. * .Her

Although ⁵ is a surface finish of a pencil or other rod-like article, the package still remains an integral part of the article to be wrapped, even after being shrunk.

The essence of the solution

The invention is a device for removing flat tubular line packages from a container and subsequently opening them, which removes the above-mentioned drawbacks while allowing the package to be prepared for machine packaging. The device consists of two parts provided with air holes connected to a vacuum source. The upper part is adjustable between the container and the lower part from above. On the one hand, the upper part removes the tubular tubular package from the flat container by means of a vacuum, to whose source the air holes are connected. Upon approaching the upper part to the lower part from above, the flat tubular segmental casing partially opens under the action of a vacuum from the air holes in the lower part.

If the upper and / or lower parts are provided with a longitudinal groove into which the air openings open, then the suction fills the wall of the flat tubular segmental package and the extent and shape of the opening are defined by the size and shape of the longitudinal groove.

The device according to the invention is schematically shown in cross-section in the two extreme positions in Figs. 1 and 2; Fig. 3 is a general view of a flat tubular segment, while various exemplary embodiments of longitudinal grooves are shown in Figs. 4, 5 and 6.

Description of an exemplary embodiment. The upper part 2 is adjustable between the reservoir 6 and the lower part 3 by means of a movement device (not shown here). The lower part 3 and the reservoir 6 are fixed to the frame 1. Neither the vacuum source nor the connecting pipes to both parts 2, 3 are shown. In Figures 1 and 2, the lower part 3 is provided with a longitudinal groove 5 into which the air openings 4 enter. Also shown in Fig. 5 is the lower part 3 with a longitudinal V-shaped groove over the entire width of the profile of the lower part 3. Longitudinal. The grooves 5 can also be formed in both the parts 2, 3, as shown in FIGS. 4 and 6. The size and shape of the grooves 5 are chosen according to the profile of the packaged goods.

The upper part 2 sucks under the vacuum a flat tubular segment O placed on top of the container 6, to which the upper part 2 has been placed from above. Subsequently, the upper part 2 is displaced in the indicated direction with the flat tubular tubular wrapping O attached to the lower part 3. By applying a vacuum in the air holes 4, the wrapper is partially opened when the two parts 2, 3 are brought closer together. If at least one of the parts 2, 3 is provided with a longitudinal groove 5, it defines the size and shape of the opening of the package O.
