Definitions

  • the invention relates to a packaging machine according to the preamble of claim 1.
  • Such a packaging machine is known from DE-B-24 37 127.
  • a drive is provided which, depending on a print mark sensor, moves all workstations together during a feed movement together with the material web and in a subsequent backward movement against the movement of the material web.
  • a drive is provided which adjusts two working stations relative to one another depending on the position of the sealing seams produced in the sealing station.
  • the material webs processed with such packaging machines usually have printing marks for identifying the repeat length provided in the context of the printing.
  • the location of the individual work stations and their distance from each other are preset depending on the target size of the repeat length. Difficulties arise during operation because the repeat length is usually not constant.
  • the object of the invention is to design a packaging machine of the type described in the introduction in such a way that adaptation to repeat lengths is possible in a simple manner.
  • the packaging machine comprises a frame 1 which comprises side walls 15, 16 and feet 3 carrying these.
  • a first work station 4 designed as a molding station, a second work station 5 designed as an evacuation sealing device and a third work station 6 designed as a cutting device are carried by the frame.
  • each of the side walls 15, 16 is designed as a profile having an essentially U-shaped cross section.
  • the two lateral legs 8, 9 of the profile are relatively long in relation to the dimension of the transverse leg 10 'connecting the two lateral legs 8,9.
  • Steel sheet is preferably used as the starting material for shaping the profile.
  • a plurality of connecting elements 10 located at a distance from one another are firmly connected to the ends at the location of the free ends of the side walls 8, 9.
  • the connecting elements can be connected to the free ends by gluing, screwing, welding or the like.
  • 5 shows a connecting element in cross section, which is prepared for a particularly advantageous resistance pressure welding by providing a corresponding ring boss 11 '.
  • a side wall of such a machine frame is composed of several profile parts 11, 12, depending on the desired length.
  • a connection element 10 is provided at a predetermined distance from the end face to be connected to the adjacent profile part, which has a bore 13 extending in the longitudinal direction of the profile part.
  • a corresponding connecting element with a corresponding bore is provided in the second transverse part at the same predetermined distance from the end face.
  • a centering part 14 is provided, the outer cross section of which corresponds in size and shape to the inner cross section of the profile parts to be connected. At the location of the bores 13, the centering part 14 also has a corresponding bore.
  • the thickness d of the centering part is a little smaller and at most equal to the sum of the distances of the two connecting elements 10 from the associated end faces.
  • the non-positive connection of the adjacent profile parts 11, 12 takes place in the manner best seen in FIG. 4 by screwing the ends together via the connecting elements 10 and the centering part 14 located between them.
  • FIG. 3 shows an end view along the line 111-111 in FIG. 1 with the workstations omitted.
  • This comprises a pair of side walls 15, 16 which are connected to a pair of feet 3 and which each carry guides 18, 19 for endless chains.
  • FIG. 2a shows an enlarged illustration of the one side wall 15 with the guides for the chains.
  • the associated connecting element 10 has a vertical bore 20 instead of the horizontal bore 13, via which the connecting element is firmly screwed to a part 21 of the foot 3.
  • a guide 22 On the inner lateral leg 9, a guide 22, best seen in FIG. 2b, is firmly screwed to the profile part by means of a spacer bolt 23.
  • the guide 22 has a holder 24 consisting of a web-shaped central part 25 and two C-or a substantially rectangular cross-section. bracket-shaped sections 28, 29.
  • the sections 28, 29 are aligned with their long sides essentially parallel to the side walls 15, 16.
  • Their inner cross section is substantially equal to the outer cross section of chain guide rods 26, 27 to be received.
  • the lateral free ends 28 ', 29' of the sections 28, 29 are bent inwards.
  • the chain guide rods are inserted into the profiles of sections 28, 29.
  • a central section which is essentially U-shaped and has a base section 30 and lateral legs which can be connected to the central part 25, the free ends 31, 32 of the side legs thus pointing outwards in the manner shown in FIG. 2b are bent over that, together with the inwardly bent free ends 28 ', 29' of the sections 28, 29, they lock the chain guide rods 26, 27 in these sections.
  • the chain guide rods have longitudinal slots in which the endless chain 33 is guided with its rollers 34.
  • the chain has clips in a known manner for gripping a packaging material web 35 to be guided through the machine.
  • rail-like strips 36, 37 are provided, which are firmly fastened to the connecting elements 10 by screws which are guided through vertical bores in the connecting elements 10 are connected.
  • the work stations have wheels 38, 39 mounted on their frames on the sides on horizontally extending axes. The work stations are mounted with these running wheels on the rail-shaped strips 36, 37 rails and can be moved back and forth on them in the longitudinal direction of the frame in a predetermined rail section to adapt to certain formats.
  • a transport device is provided through the entire machine from the entrance to the exit in the form of an endless chain 42 driven by a motor 41.
  • a print mark sensor 40 is arranged on the input side, which detects print marks attached to the material web 43 and feeds the output signal to an input of a controller 44.
  • the print mark sensor is arranged on the input side for detecting print marks on the lower web of a package.
  • the print mark sensor is arranged in the area of the supply of an upper web to cover the packs to be formed.
  • the work stations 4, 5, 6 are each provided with displacement measuring devices 45, 46, 47, which either detect the absolute position of the stations or the relative position of the stations by incremental measurement.
  • the outputs of the displacement measuring device are connected to respective inputs of the control 44.
  • the control 44 is connected on the input side to the output of a data input device 48, via which data about the desired position of the workstations can be input from the outside.
  • Each of the workstations 4, 5, 6 is non-positively connected via a spindle drive 49, 50, 51 to a respective servomotor 52, 53, 54, which in turn is connected with its control input to an output of the control 44. Furthermore, the control input of the drive motor 41 is connected to an output of the controller 44. Instead of the spindle drive, other linear drives can also be used.
  • the distances detected by the print mark sensor 40 between two successive print marks are summed up by a computer of the controller 44.
  • the controller 44 controls the actuators 52, 53, 54 in such a way that the individual work stations are tracked in accordance with the measured print mark spacings with each individual work feed of the machine.
