Definitions

  • the invention relates to a Bodenmacherzylinder a bag machine after the preamble of claim 1.
  • Pouch machines are known. They are used, for example, in DE 42 05 062 A1, DE 197 02 144 A1 and F 2 548 161.
  • that is functional core of such a machine is a bottoming cylinder.
  • This Bottom cylinder usually takes pieces of hose, which made a paper tube which has been unwound from an unwinding unit, in a tear unit to paper tube pieces or sections isolated has been.
  • the Bodenmacherzylinder takes over these paper tube pieces, locks it to its circumference and guides it during a turn various processing stations that are around the floor maker cylinder are arranged, too.
  • the hose pieces impacts formed, which are glued and folded together and on this Form solid bag bottoms. In general, the hose piece with the transported later soil ahead.
  • the bottom flaps which is used to form the Soil must be placed on top of each other, to grab and fold.
  • a The bottom flaps can be closed by using this bottom flap on a fixed resistor runs and is folded over.
  • the second bottom flap must be folded in the transport direction.
  • This bottom flap must be moved faster than that for a short time Piece of hose.
  • the scope of the Treadmill rotating parts usually sickle-shaped are formed. These are preferably driven by elliptical wheels, which are mechanically coupled to the drive of the Bodenmacherzylinders. Using the elliptical wheels, the rotating parts are briefly in such a way high speed moves faster than the hose piece move and thus be able to close the bottom flap.
  • Object of the present invention is therefore a bag machine to propose adapting the rotating parts to new ones Bag formats can be done easier and faster.
  • the task is characterized by the characteristics of the characterizing parts of the Claims 1 and 4 solved.
  • the phase position of the rotatable part is the grounding cylinder adjustable during operation of the bag machine. This will avoid to put the bag machine down for the purpose of format change. Farther the rotatable part no longer needs to be replaced when the format is changed become. A format change can thus be done much faster.
  • the movement of the Bodenmacherzylinders and the rotatable part are mechanically coupled and when in the Bag machine at least one differential is provided with which the Adjustment of the phase position is made.
  • the part which drives the rotatable parts can be opposite to the drive twisted the Bodenmacherzylinders. This can for example mechanically, but also by means of a servomotor.
  • FIG. 1 shows a sketched side view of a bag machine 135 Figure has been added to the technical background of show devices of the invention. This is primarily about the description of the core function of such a bag machine used in the Area of tubing section formation and grounding. For this purpose is at this point once again noted that the Bodenmacherzylinder and the Bodenöffner also in the German Auslegeschriften 1611699 as well 1080846 are explained.
  • the bagging machine shown in FIG. 1 becomes a Paper web 100 from right to left in the transport direction of the paper web or the bag components z supplied.
  • the Hose forming station 101 which includes the rollers 102, which also includes the Lead conveyor belt 103, the paper web to a tube 130th merged.
  • This process is also symbolized by the lines 104, which represent the edges of the paper web when folded.
  • the tear-off unit 131 To this Tear-off include initially the preferred rollers 106, which the paper web lead and the paper webs in opposition to each other Lock preferred rollers. After passing through the nips between the preferred rollers of the paper tube from the knife 108, which at the rotating blade carrier 107 is locked, which the knife along the dashed path 107a leads, perforated. Forms itself during the perforation process the counter-pressure cylinder 109 a counter-position. On the knife carrier 107 are two knives 108 attached so that upon one rotation of the knife carrier 107 two cross sections on the tube web 130 arise.
  • Figure 2 shows once again a bag, as in such a Bag machine 135 can be made.
  • This bag 123 has Gussets 122.
  • FIG. 3 shows a somewhat more advanced bag 121 with carrying handles 124, which has been additionally fixed with a cover sheet 125 to the bag are.
  • carrying handles and the method and apparatus for their preparation and the attachment to the bag are known in the art and are for example in DE 42 05 062 A1, which was already mentioned at the beginning, shown.
  • carrying handle stations form part of the Bag machine, which are downstream of the Bodenmacherzylinder.
  • the But carrying handle station can also already before the hose forming station Figur 6 also clarifies once again the design of the Bag. So the width and height of the bag is shown again. The Height of the bag is determined by the length of hose section, which of the Abr constitustation is defined determined.
  • the height of the bag or the hose section length in the first Line through the diameter of the circumferential circle of the knife carrier 107th certainly.
  • the width results from the width of the paper web and the Settings of the hose station 101. Even with width changes must extensive changes to the settings of the tools, for example on Bodenmacherzylinder, be made.
  • FIG. 4 shows a section of the ground station 117 in a detailed view.
  • the drive of the bottom folding station is effected by a shaft, not shown, which supplies a deflection gear 1 with a drive torque.
  • the deflection gear is preceded by elliptical gears, which provide for differences in speed compared to the speed of the drive shaft.
  • the shaft 4 which in turn ends in a differential gear 5.
  • This differential gear 5 drives another gear 6.
  • the gear 6 drives the shaft 8 via another gear 7. From the shaft 8 torque from the reversing gear 9 on the rotatable part, which is designed as a sheet 10, transmitted.
  • This sheet 10 which may be sickle-shaped, is thereby set in rotation. Due to the temporarily higher rotational speeds during a revolution compared to the rotational speed of the drive shaft, the sheet 10 is able to fold down the bottom flap in the transport direction of the hose piece.
  • the deflection gear 9 is fixed to a carrier 11. This carrier 11 is slidably mounted in the direction of the double arrow A in the direction of the rail 12. In this way, the closing mechanism, consisting of the deflection gear 9 and the sheet 10 can be adjusted to the width of the hose piece without having to replace the sheet.
