  • the bags can be on the transport device regarding the flat bag machine in mutual correct Alignment.
  • the one in the transport device then properly mutually aligned bags from the usually existing holding device or gripper arrangement recorded and fed to the flat bag machine will.
  • the isolated bags are therefore before handover in the, for example, transport grippers trained as a rotary machine in front of the Flat bag machine already aligned correctly with each other positioned as they place in the flat bag machine should find.
  • the correct positioning of the individual in the cutting station Bags on the transport device can be easily Way done in that the transport device accordingly is driven at different speeds.
  • a very simple design of such a transport device is realized by an arbitrarily drivable conveyor belt. If the conveyor belt is designed as a suction belt the bags placed on the conveyor belt can be placed in their respective correct orientation easily maintained and be fixed in position. On the conveyor belt, the Bag then related to their respective transfer position the first workstation, for example as a rotary machine trained flat bag machine are brought.
  • Cutting station only a single cutting device. This can also apply if several bags are clocked in the Flat bag machine to be traded.
  • This one Separating device can be used as a rotary knife or rotary punch or also as a reciprocating cutting knife be trained. The cutting edge of the cutting device must be used during the respective cutting or cutting process at least approximately the speed of those traveling Have packaging material web.
  • Counter roll is formed as a suction roll, can be the same one with a corresponding corrugated, for example Separation line sucked-in waste piece generated by punching and the piece of waste from its further transport with the individual Bags are held. Such a piece of waste is shown as an example in the drawing.
  • the cutting device a Feed roller device for the still inseparable packaging material web to arrange.
  • the transport device can also be motor drives have.
  • the motor drives are on the clock sequence and the mutual spacing of the individual bags matched. If a counter roll is arranged, it is advantageous these are also driven by a motor drive.
  • the packaging material web is advantageously timed Cutting station fed. Be within one bar step a certain number in succession in the cutting station isolated from bags from the packaging material web. This group of individual bags is transported one after the other by a transport device added. The mutual distance between the bags this group in the transport device corresponds to that mutual distance the bags in the flat bag machine should have. A change in the mutual Distance of the bags by the holding device with which the Bags from the transport device to the flat bag machine are therefore not necessary.
  • a flat-bag machine that is designed as a rotary machine and works in a clocked manner 10 has several arranged one after the other Workstations in which two bags at a time can be handled.
  • a first work station 12 there are two bags each 16.1 and 16.2 simultaneously by a gripper arrangement 22 for each bag 16.1, 16.2 taken over.
  • the two bags 16.1, 16.2 by two grippers 24 for the bag 16.1 and two grippers 26 for the Bag 16.2 held. Bags 16.1 and 16.2 are already positioned on the conveyor belt 20 so that you are centered Distance 28 the central distance between the two pairs of grippers 24, 26 corresponds.
  • the two gripper assemblies 22 therefore need only perform one movement within one level at a time to be able to.
  • the individual bags are made from a packaging material web 32 in the present case, fold over once and section by section Attaching longitudinal seal seams 34 and attaching an in Fig. 1, not shown, in the fold area 35 of the packaging material web 32 running transverse sealing seam.
  • the packaging material web 32 is over preferred rollers, one of which Preferred roller 36 is shown in front of the cutting station 30 in Transport direction 38 moved in cycles.
  • Preferred roller 36 is shown in front of the cutting station 30 in Transport direction 38 moved in cycles.
  • Within a Clock step in the present case are two bags of Cutting station 30 fed, passed through the same and placed on the conveyor belt 20.
  • the preferred roller 36 correspondingly by means of a servo motor M1 is driven, an upper roller 40 is assigned. Between the preferred roller 36 and the counter roller serving upper roller 40, the packaging material web 32 is moved through.
  • the with longitudinal seal seams 34 and a lower transverse seal seam provided packaging material web 32 reaches the cutting station 30.
  • the cutting station 30 has a top view of the packaging material web 32 acting rotary punch 42.
  • a lower counter roll 44 is positioned below the Is the packaging material web 32, opposite the rotary punch 42.
  • the counter roller 44 has a rotational speed adapted to the rotary punch 42.
  • the rotary punch 42 is by a not shown Drive motor set in rotation so that its cutting edge 48 at least during their contact with the packaging material web 32 has an orbital speed that of the speed corresponds to the packaging material web 32.
  • the sections of the packaging material web are cut by the cutting station 30 32 in the area between the longitudinal seal seams 34 isolated and thereby individual bags 16 made then be transferred individually to the conveyor belt 20.
  • the flat bag machine 10.2 shown in FIG. 2 differs differs from the flat bag machine shown in Fig. 1 10 in that not two, but four bags 16 (16.1, 16.2, 16.3 and 16.4) together in the Flat bag machine can be handled.
