EP1354798A1 - Apparatus for filling plastic bags, opened at one side - Google Patents

Abstract

The machine for the filling of film bags open on one side operates in a way such that the bag (3) reaches the filling station (7) with its stepped filling opening (6) lying uppermost and inclined. A device is provided on the filling opening for the opening of it by an air blast. The full bag on the side opposite the filling opening has a suspension flange (4). At the end of the transporting surface (10), in contact with a welding station, an endless conveyor belt (12) acting from above is provided for the controlled leading away of waste strips (5).

Description

The invention relates to a device according to the preamble of claim 1.

This device is used to fill different bags Formats in a width of 40 to 300 mm and a length of 100 to 400 mm. Such bags are common made from a wide variety of plastic films. she have a stepped filler opening that allows filling by hand or by a machine.

The invention is based on the object of a device of the type mentioned at the beginning to create a safe and quick filling guaranteed.

This task is fundamentally determined by the characteristic of Claim 1 solved.

The fact that the bag to be filled individually with the graded Filling opening on top of a blowing device is fed, its exact orientation on the conveyor made sure. The one opposite the filling opening Edge is brought into contact with a corresponding by gravity Stop angle (guided) positioned. The same applies to the donated filling product, which accordingly slips into the foil bag to be filled and also arrives at the stop bracket.

The film bag points to the one opposite the filling opening Side advantageously a suspension flange which is a bit more stable and so the clean system on the Support bracket supported. At the same time lies after final Processing and sealing a finished manageable Product before.

At the end of the device, one of Conveyor belt acting above the waste strip controls controlled, so that this with the finished product (bag with packaging) is not mixed.

In the following the invention with reference to a Embodiment explained in more detail.

The device shown in the drawing consists of a machine frame 1 which carries a belt conveyor 10. The conveying level is, as can be seen in particular from FIG. 3, inclined.

There is a magazine at the beginning of the conveyor line a separating device 2. Located in the magazine a large number of foil bags 3, which are in this embodiment a hanging tab 4 and this opposite have a filling opening 6.

The foil bags dispensed from the separating device 2 3, as can be seen in FIG. 2, reach the inclined position Delivery level that the filling opening 6 above so higher lies as the opposite hanging tab 4.

The film bags 3 are individually in the area of the filling station 7 moves. Here they are through the blowing device opened at the graduated filling opening 6. It is now possible by hand or automatically the filling material, for example Fill in pen. The filling bags are with the Suspension bracket 4 and lying along a stop bracket 9 conveyed to the welding station 8. Here is done by a corresponding welding bar a separating welding, i.e. the filling opening is closed and at the same time a waste strip 5 remains. The filled bag will into a collection container and the waste strip 5 by one conveyor belt 12 acting from above checks into a waste container 15 funded.

In Fig. 3 it can be seen that the separating device 2nd is at a higher level than the section of the funding level, which promotes the hanging tab 4. The funding level is determined by the conveyor belt 10 and the stop angle 9.

4 shows how the conveyor is designed in detail is. It is formed by two flat belts, the opened mechanically to hold the foil pouch.

The different transport directions are indicated by arrows.

FIGS. 5 and 6 show how the filling station 7 is specifically constructed in this embodiment.

Compressed air is supplied via a hose 13 to the foil bag 3 at the stepped fill opening 6 opens. With With the help of a slide 14, the filling material 11 is opened Foil bag entered, as can be seen in Fig. 6.

Claims (3)

Device for filling film bags open on one side, which are individually fed to a filling station, characterized in that the film bags (3) with the stepped filling opening (6) are inclined at the top and reach the filling station (7), and
that a device is provided on the stepped fill opening for opening this stepped fill opening by blowing air. Apparatus according to claim 1 or 2, characterized in that the filling bag (1) has a suspension flange 4 on the side opposite the filling opening (6). Apparatus according to claim 1, characterized in that at the end of the conveyor plane (10), following a welding station (8), an endless conveyor belt 12 acting from above is provided for the controlled removal of the waste strip (5).
