Definitions
- the invention relates to a device for producing bags according to the preamble of claim 1.
- Devices for the production of bags or bag packs in which a packaging material band is formed into a tube and the tube is pulled forward and divided in intervals by one bag length, are essentially divided into two types, namely in pliers-pulling machines and belt or roll-pulling machines.
- the tube In the case of forceps drawing machines, the tube is advanced by a bag length by a reciprocating or moving up and down transverse sealing device, while at the same time the tools of the transverse sealing device make transverse seams on the hose and divide a bag.
- the sealing time corresponds to the preferred time.
- a disadvantage of this type of tubular bag machine is that when the tube is pulled forward due to the pull, the end is wedge-shaped, so that a bottom is prevented and the capacity of the bag is not fully utilized.
- the hose is gradually advanced by a bag length of a pair of conveyor belts or reels by frictional engagement and the transverse sealing seams are each attached by a stationary sealing device during standstill.
- a clean stand-up base can be formed, but it has the disadvantage that the times for the cross-seam sealing and for the tube feed add up and the performance of this type of machine is therefore lower than that of the forceps pulling machine.
- a tubular bag machine has become known from DE-OS 2134 475, in which the tubing is carried out both by a reciprocating cross-sealing device and by conveyor rollers or belts which convey in cycles.
- the transverse sealing device is only moved back and forth by part of the length of the bags to be manufactured and the remaining tube length for a bag to be manufactured is advanced using the conveyor rollers or belts.
- the production of bags with the same length is very difficult.
- the time available for cross-seam sealing is not fully used.
- the object of the invention is to provide a device for producing bags, on which bags with a shaped bottom can be formed, and on which bags with very strong transverse sealing seams can be produced.
- the solution to this problem is specified in the characterizing part of claim 1.
- bags and bag packs with sealed seams of high strength and very high produce delivery are sealed seams of high strength and very high produce delivery.
- the bags made have a large capacity due to a molded stand.
- the configuration of the device according to claim 2 provides a simple and uniform drive for the transverse sealing device and the rotating conveying device.
- the measures according to claim 3 lead to a simple coupling of the transverse sealing device with the rotating conveying device.
- a form and fill tube 12 is suspended in a vertical orientation on a plate 11 which projects from a machine frame 10.
- a shaping shoulder 13 surrounds the upper part of the shaping tube 12, via which a heat-sealable packaging material strip 1 is pulled off a supply roll, not shown, and is shaped around the shaping tube 12 to form a tube 2.
- the overlapping edges of the packaging material strip 1 formed into the tube 2 are sealed together by a heated heat-sealing jaw 14 against the molded tube 12.
- an endless conveyor belt 15, 16 and a pair of transverse sealing jaws 17 are arranged on both sides of the lower part of the molded tube 12.
- the conveyor belts 15, 16 rotating in cycles are arranged around upper and lower tere Ümlenkmann 20, 21 and 22, 23 guided so that their mutually facing dreams abut by friction on the outside of the tube 2 guided on the molded tube 12.
- the two strands of the perforated conveyor belts 15, 16 which rest against the hose 2 run in front of suction boxes 24, 25, in which a negative pressure is built up.
- the pair of transverse sealing jaws 17 is arranged in a frame-like slide 26 so that the two transverse sealing jaws can be moved and pressed against one another, compressing the tube 2 transversely and dividing a bag 3 from the lower end of the tube.
- a bag 3 is divided, a head seam is formed on the tube 2 at the bottom and a bottom seam is formed at the top, and the bag 3 located underneath is separated therebetween.
- a bag 3 is divided while the carriage 26, which can be raised and lowered on two vertical rods 27, 28, is moved downward by one bag length by a stepping gear 30 via a rocker arm 31 and a pull rod 32.
- the two conveyor belts 15, 16 are driven synchronously, so that the hose 2 is not only conveyed by one bag length by pulling at the compartment location but also by thrust.
- a vacuum is generated in the suction boxes 24, 25 while the hose is being pulled, so that the hose 2 is pulled firmly onto the conveyor belts 15, 16.
- the transverse sealing jaws 17 are moved apart, thereby releasing the hose 2 and the divided bag 3.
- the carriage 26 is then raised again.
- the latter drives the chain drives 35, 36 in the opposite direction via the tabs 41, 42, the upper sprockets 37, 38 rotating freely due to the action of the freewheels 34, without the lower deflection wheels 22, 23 of the conveyor belts 15, 16 to turn.
- the tabs 41, 42 it is also possible to see pneumatic cylinders which, during the hose advance, increase the feed path of the conveyor belts relative to the transverse sealing device by means of a superimposed movement, so that a particularly pronounced formation of a bottom on the bags is possible is.
- two folding slides 44, 45 are arranged on the slide 26 a little above the transverse sealing jaws 17, which each pull a side fold on both sides of the tube 2 when the transverse sealing jaws 17 go together, as is known, for example, from US Pat. No. 3,201,913.
- Such folding slides can also be arranged below the transverse sealing jaws 17, so that 3 side folds are also drawn in at the top of the bag.
- a high degree of filling of the bag packs is achieved by attaching side folds in the top and bottom area of the bags.
- the tube 2 is pulled through the Shaped tube 12 each introduced a quantity of product in the end of the hose 2.
- empty bags can also be produced with the described device, filling being omitted and only a bottom seam being attached to the tube by appropriate design of the transverse sealing jaws.
- rollers can also be arranged which are driven in the same way as the conveyor belts.
- perforated conveyor belts to which the hose is held by vacuum
