Definitions
- EP-B-667 288 describes a method and an apparatus for Manufacture of 3 sealed edge bags with welded closure profile known.
- a packaging film is taken from a stock gradually withdrawn and around a collar to a cylindrical, molded downward hose. Adjacent to the Two overlapping longitudinal edges of the film become closure profile pieces fed between the film edges and with the foils by sealing jaws moved against the foils in cycles sealed.
- the product to be packaged is portion by portion Filled through the top of the collar. Then will the package thus formed with a transverse sealing seam by clockwise working sealing jaws sealed and the package separated. Then there is a feed step, followed by the next Hose section is filled.
- the closure profile pieces are approximately as long as the inner distance between the cross seal seams.
- a similar device of this type is described in WO 99/20529, which also works step by step.
- a further device for the production is known from 3-sealed edge bags. It is about a horizontal form, fill and seal machine.
- the zipper is considered continuous continuous band between longitudinal edges of a continuous peeled off film wrapped around the products and at the same time the film is welded to the free edges.
- Cross seal seams are formed in a cross sealing station and separated the individual bags.
- the object of the present invention is a method and to provide a device of the above type with which the packaging speed can be increased. This task is solved by the combination of features of claims 1 and 4.
- the device according to FIGS. 1 and 2 has a first supply 10 for a thermoplastic packaging film 11 or a composite film and a second supply 12 for a closure profile 13 (Zipper).
- the film 11 is in a folding station 14 via a Fold edge in a known manner around the at regular intervals Products 15 supplied in a likewise known manner to one flat, horizontal tube 16 folded.
- the folding station 14 is in Figures 1 and 2 in the transport direction A of the hose 16th drawn very shortened.
- the stock 10 can also contain an already folded hose.
- the hose 16 is continuously with a first feed unit 17 from the supply 10 deducted.
- the unit 17 consists of two pairs of transport rollers 18, 19 and 20, 21.
- Each roll 18-21 consists of two coaxial single rollers mounted on the same shaft 25, 26 18a, 18b, 20a, 20b. At least one of the rollers 18, 20 of each pair is driven by a servo motor 27, 28. The single roles 18a, 20a grip the film along its free edges 29. The individual rollers 18b, 20b have a circumferential groove accordingly half the cross-sectional profile of the closure profile 13.
- the motors 27, 28 are connected to rotation angle sensors 31.
- feed unit 17 can also be a single motor 27 may be provided, the two pairs of rollers 18, 19, 20, and 21st drives synchronously.
- the motors 27, 28 and angle sensors 31 are connected to a control device 32.
- the closure profile 13 is by a second feed unit 37 deducted from stock 12.
- the unit 37 comprises a pair of transport rollers 38 by a servo motor 39 with an angle sensor 40 is driven, which also with the control device 32nd are connected.
- the rollers 38 have a circumferential groove 41 accordingly groove 30.
- Downstream of rollers 38 is a separator 42 for separating the closure profile 13 into closure profile pieces 43 adjustable length arranged.
- the facility 42 consists of a rotating knife 44 that by a another servo motor 45 is driven with an angle sensor 46. This are also connected to the device 32.
- the knife 44 works with a rotating or stationary counterholder 47 together.
- the profile pieces 43 are from the unit 37 between the two Foils spaced from but adjacent edges 29 fed.
- Between the two pairs of rollers 18, 19 and 20, 21 are two longitudinal sealing stations 50, 51, to form a longitudinal sealing seam 49 and for sealing the film 11 on both sides onto the Profile pieces 43 arranged.
- the stations 50, 51 consist of each a pair of continuously at least almost contiguous, heated sealing jaws 52, 53. These can on the Film 11 facing side be coated with PTFE.
- the foil 11 is continuously between the Jaws 50, 51 pulled through.
- the rollers 20, 21 can be cooled his. They then ensure that the sealed seams cool down quickly.
- a cross sealing station 56 Downstream of the pair of rollers 20, 21 is a cross sealing station 56 arranged. It consists of two circulating on oval tracks 57 Cross sealing jaws 58, 59. One can be placed in the jaws 58, 59 Separating device consisting of a knife 60 and a counter holder 61 be integrated. The way of guiding the jaws 58, 59 is known in the art. With this knife the Hose 16 divided into individual bags 66.
- a sensor 62 can also be arranged on one of the rollers 18, 19 are also connected to the control device 32 is.
- the sensor 62 can be, for example, a force sensor or a Be path sensors. If the leading end 63 of a profile piece 43 between the rollers 18b, 19b, these are namely slightly moved apart to generate the necessary contact pressure the film on the profile piece 43. This increased contact pressure or the resulting shift is with the feeler 62 recorded.
- the device described works as follows:
- the Slide 11 is continuously withdrawn from unit 17.
- the Unit 37 also transports the profile 13 continuously.
- the sensor 62 responds, its signal triggers via the device 32, delayed by an adjustable, with the angle sensor 31 measured angle of rotation, one rotation of the knife 44 by 360 °, with the rotational speed of the cutting edge the feed rate of the profile 13 corresponds to that with the pull-off speed of the film 16 is synchronized.
- the motor 39 briefly and then accelerates it back to the synchronous speed. To this A distance x between the leading end 63 of the Profile piece 43 and the trailing end 64 of the previous one Profile piece 43 formed.
- This distance x corresponds to the Width b of the transverse sealing jaws 61 or is slightly larger.
- the transverse sealing seams 65 are only in this gap between two successive profile pieces 43 formed. This will make one perfect sealing and good tightness achieved. Because of the continuous deduction, high packaging performance achieved.
- the command to initiate the separation movement by the knife 44 also derived exclusively from the angle of rotation of the pair of rollers 18, 19 be measured with the sensor 31.
- the device 37 can also be used to retrofit existing ones Tubular bag packaging machines are used.
- the device is particularly suitable for horizontal tubular bag packaging machines.
- Figure 3 shows a section of a variant of the embodiment according to FIGS. 1 and 2.
- the rollers 38 and the supply 12 in the vertical median plane through the sealing jaws 53 arranged. 3 is the vertical plane through the rollers 38, the knife 44 and the stock in contrast, arranged at an acute angle to this median plane.
- the cut closure profile pieces 43 are fed to the rollers 18b, 19b by a bent guide rail 70.
- This variant can have advantages when feeding the products 15 have between the folded film 11.
