Definitions
- the invention relates to a method for producing foil bags, in which two Films to form the side walls of the film bags and a bottom film to form of the bottom of the film bag are fed and connected together, and a Device for performing the method.
- Foil bags are used to hold a filling, e.g. Beverages. Such Foil bags are e.g. from two side foils on two opposite Edges are welded together. There is a between the respective third edges The bottom foil is welded in place, which in the unfolded state is a stand represents and forms space for the contents between the side foils. After the filling the fourth side edges are welded together.
- Automated processing lines are used to manufacture such film bags the side foils and the bottom foil are unrolled in one piece from corresponding supply rolls, placed on top of each other in the correct layer sequence and then, as described above, welded together. The resulting series of foil bags is then cut into individual foil bags along the weld seams.
- a malfunction can easily result in the cutouts defective, misplaced or not manufactured at all. Since the bottom sheet between the two side films come to lie and accordingly in the unfilled Condition of the foil bag is not visible, a visual inspection can be carried out to check whether the bottom film has corresponding recesses, only with great effort and if the further processing is slowed down or interrupted be performed.
- At least holes are punched into the bottom film during feeding, which holes in Running direction of the bottom film have a distance that is the width of a film bag corresponds.
- the arrangement of these holes is essentially symmetrical to the center line the bottom film in the running direction.
- the bottom sheet is folded along this center line.
- the punching and folding process can also be interchanged during the feeding process a measurement is carried out after the punching process, with the aid of which it is determined whether punch holes have been created.
- the side foils and the folded bottom foil are placed one on top of the other, on the future side edges of the foil bags connected that where the bottom sheet is between the side sheets, the side edges only directly connected to each other through the punch holes. Finally, the connected film sequence cut so that the side edge connection area is divided between two foil bags.
- the base film is thus already introduced checks whether the punched holes are in the correct position and at the correct distance were introduced.
- the optical measurement can e.g. to be used, an acoustic or visual warning signal to the operating personnel to enter or stop the film bag manufacturing facility. Because the detection the punch holes before the bottom film is inserted between the side films happens, no defective foil bags are made afterwards should be sorted out.
- the method according to the invention thus increases reliability and avoids wasted time due to malfunctions.
- the punching process can be carried out before the folding process of the bottom film. So the presence of the punch holes for all punched holes that are arranged side by side perpendicular to the direction of the bottom film are carried out individually and precisely. However, it is also possible that the folding process is carried out before the punching process. In this way, the Stamping process and the hole measuring process effectively and with a minimum number of Punching or measuring devices performed.
- the foils can be glued together along the future edges.
- welded edges are very simple and reliable.
- the measurement of whether the punch holes have been made can e.g. with corresponding Touch sensors are performed.

- Another advantageous embodiment provides proximity switches that are used with metal Films can be used and less susceptible to pollution and Are moisture.
- the punch holes are around the center line of the bottom sheet on which the bottom sheet is folded is arranged symmetrically. This can be a single punch hole in the direction be provided perpendicular to the running direction of the base sheet, that when folding the base sheet is also folded. An increase in the reliability of the production process and However, the stability of the foil pouch is achieved if there are two punch holes are provided in the direction perpendicular to the running direction of the base sheet, which be placed on top of each other by the folding process.
- a Measurement to determine whether bottom film is being supplied at all A Malfunction of the feed mechanism of the bottom sheet can easily be done in this way can be detected and side films can be prevented from being joined together without any bottom film between them. Also a film tear or the film end can be determined in this way.
- the senor can also be used to detect when between Sensor and a downstream processing station malfunction, e.g. a film tear occurs. This is recognized by the fact that the signal state of the Sensor does not change.
- this measurement is again optical, which is a contactless detection enables, or carried out with the aid of a proximity switch.
- the method according to the invention can be carried out with great effectiveness if the two supplied side foils each have a width that the expansion of several Foil bag corresponds and a corresponding number of bottom foils is fed.
- several foil bags can be produced side by side and individual ones Components such as the connection or cutting device for cutting in individual floor foils, only have to be provided once.
- the film bag manufacturing device for performing the inventive Method has a punching device for punching the holes in the Bottom film, which are arranged symmetrically to the center line of the bottom film, and a Measuring device for the detection of the punch holes.
- a second measuring device can advantageously be provided to demonstrate whether there is a bottom sheet.
- An advantageous embodiment comprises a light barrier as a measuring point.
- the signal A light barrier is easy to read and can be used to generate a warning signal or used to switch off the device.
- Another advantageous embodiment comprises a proximity switch as a measuring point.
- a proximity switch is less susceptible to contamination and Moisture and can be used especially with metal-containing foils.
- FIG. 4 shows a finished foil bag 2.
- 10 denotes weld seams which are attached to the Side edges connect the side foils with each other (hatched area). 16 designated the area in which the bottom foil is welded to the side foils (by crosses shown). Die cuts 20 are provided in the base film in the base area, through which the side foils are welded together directly in the floor area. This leads to direct side foil / side foil welds 18 in the bottom area. After the bag has been filled, the upper edge is sealed with another weld seam 14 locked.
- FIG. 5 shows a still empty and unsealed film bag 2 in Side view shown. The width is indicated by x.

- 64 is the transport device of the collapsed slides.
- Figure 2 shows the supplied base film 8 after passing through the punching device 30.
- a distance x which corresponds to the width of an unfilled plastic bag, there are punched holes 20 provided, the distance from the center line 22 is y in each case.
- the dimensions y or x are a few millimeters or centimeters, depending on the dimensions of the finished foil bag 2.
- Figure 3 shows a series of foil bags after passing through the welding device 36 and before passing through the cutting device 38 according to the arrangement the figure 1.
- the height of the foil bag perpendicular to the conveying direction 50 is z designated.
- 24 denotes the lines along which the row of foil bags passes the knife 44 of the cutting device 38 is to be cut.
- 22 denotes the Center line of the bottom film 8 (see FIG. 2), which is in this state after welding represents a folded edge.
- the method according to the invention is as described with the embodiment described follows.
- the feeders 40 e.g. designed as rotating rollers can promote both the side foils 4, 6 and the bottom foil 8.
- the bottom foil 8 is unwound from the supply roll 48 (see FIG. 1). Downstream of the Supply roll 48 are punched holes 20 into the bottom film with the aid of the punching device 30 introduced, which are arranged symmetrically to the center line.
- the bottom sheet will then passed through light barriers 32, which are arranged according to the position of the punch holes are. If a punch hole 20 passes through a light barrier 32, a corresponding one generates an electrical signal, which via the signal line 62 of the controller 60 is fed.
- the controller 60 also receives a signal about the speed of the supply roll 48 and the punching frequency of the punching device 30. From the speed of the bottom film and the punching frequency, the control device 60 calculates the distance between the Punch holes 20 are to be expected on the light barrier 32 and compares this calculated Value with the signal from the light barriers 32.
- the Light barriers 32 constantly generate a signal, even if there are no punch holes 20 are present and the light barriers 32 accordingly no signals at all output, there is no match between the calculated and the measurement signal of the light barrier 32 ahead and the controller 60 generates a warning signal which e.g. to stop the entire device can be used.
- the light barriers 32 no signals if there is a malfunction downstream of the punching and folding device occurs, e.g. a film tear. Then no more foil is requested and the signal state does not change.
- the punched base sheet 8 is folded in the folding device 34 along the line 22 and brought between the side foils 4 and 6.
