Description

Device for separating stacked packaging inserts The present invention relates to a method for separating one into the other stacked packaging inserts, primarily made of thin, elastic e.g. also metallized plastic film, which are trough-shaped or cup-shaped Have depressions.

The packaging inserts are used for reasons of transport and storage Delivered in stacks and, after being separated, serve as sorting inserts e.g. for Confectionery, electrical parts, Christmas baubles and the like.

There are methods for separating stacked packaging inserts known, in which the pulling off of the foremost packaging insert through Suction takes place by means of rubber eyes. A real separation result depends on the liability of the packaging inserts to one another. It often happens that when peeling off, the subsequent insert is also deducted due to cohesion.

Even with a method in which tong-shaped grippers are used for separation are used, which primarily capture the packaging inserts at their edges, The possibility of subsequent missions getting stuck is not excluded.

There is one more decisive disadvantage in the aforementioned processes ascertain. The packaging inserts are not pulled off the stack in a plane-parallel manner, whereby the cup-like depressions jam against one another.

The present invention has the object of packaging inserts to separate a stack, with a suction die with all sides opposite the indentations of the insert with reduced surface a reduction in the size of the insert by shrinking it on the suction patrix is created, thereby loosening caused by the surfaces of the adjacent insert and then the extension of the Bet is made from the stack.

An embodiment of the invention is based on the drawings explained in more detail.

Figure 1 shows a stack of packaging inserts in the magazine and one Suction male when approaching the extraction point.

Figure 2 shows the suction male in the removal position on the magazine.

According to FIG. 1, the stack (i) consists of nested packaging inserts (2) in a magazine guide (3) which is horizontal, vertical or inclined can be arranged, stored. At the removal point of the magazine are adjustable Stops (4) with angularly bent leaf springs (5) are arranged, which the stack (1) wear. The angled ends (6) of the leaf springs (are slightly narrower than the edge of the packaging inserts (2) and are about 3 mm in front of the base (7) the magazine guide (3). A separating device is assigned to the magazine, in a guide not shown here and a drive known per se is brought plane-parallel to the extraction point. The separating device consists of a male mold (8), the shape of which corresponds to the packaging insert (2), however, it is made somewhat smaller on all sides. This patrix is on a plate (9) attached, on the protruding edge of which an elastic covering (10) is applied is. The plate (9) is on a suitable by means of the bolts (11) and compression springs (12) Traverse (13) mounted elastically.

The separating device is now brought up to the magazine, until the spring-mounted plate (9) with its elastic covering (10) is in a non-positive manner Connection with the magazine guide (3) (Fig. 2) is. The stack (1) and the leaf springs (5) pushed back accordingly. The foremost packaging insert (2) has centered itself with the male part (8), its edge (14) lies tightly on the elastic covering (10).

The hose line (15) is in a known manner applied with a vacuum. Through the suction channels (16) is now the foremost packaging insert (2) with its cup-like depressions on the male mold (8) sucked and reduced in size on all sides due to its natural elasticity, whereby at the same time its edge (14) is pulled from the leaf spring ends (6). In this The packaging insert has completely detached itself from the stack (1).

The separating device with the sucked-in packaging insert is guided away from the magazine plane-parallel. By venting the line (15) or Pressurized air is applied to the insert at the appropriate point on the patrix (8) solved.

Claims (2)

Patent claims 9 Device for separating packaging inserts stacked one inside the other, mainly made of thin, elastic, e.g. also metallized plastic film, which Are formed trough-shaped or also have cup-like depressions, thereby characterized in that stacked packaging inserts in a magazine (3) by stops (4) positioned at the removal point with angled leaf springs (5) are, however, a male mold (8) that corresponds to the shape of the packaging inserts it is somewhat reduced on all sides and has an elastic at its protruding edge Covering, sucks off the foremost packaging insert by vacuum by whose original shape is reduced by its natural elasticity, at the same time whose edge (14) pulls off the leaf spring ends (6) and thus completely from the replaces subsequent packaging inserts. 2. Apparatus according to claim (1), characterized in that the angled ends (6) of the leaf springs (5) over the base (7) of the magazine guide (3) protrude so that the resiliently mounted male part (8) at the removal point Push back the stack (1) accordingly in order to make an exact contact with the foremost To ensure the use of packaging.
