Definitions

  • the invention relates to a bottoming cylinder of a bagging machine according to the preamble of claim 1.
  • Pouch machines are known. They are for example in fonts DE 42 05 062 A1 . DE 197 02 144 A1 and F 2 548 161. Also the DE 806 312 shows such a bag machine.
  • the functional core of such a machine is a floor maker cylinder.
  • This Bodenmacherzylinder usually takes over pieces of tubing, which has been separated from a paper tube, which has been unwound from a unwinding unit in a tear-off unit to paper tube pieces or sections.
  • the Bodenmacherzylinder takes over these paper tube pieces, arresting them at its periphery and leads them during one revolution to various processing stations, which are arranged around the Bodenmacherzylinder to. In this case, impacts are formed on the pieces of hose, which are glued and folded together and form solid bag bottoms in this way. As a rule, the piece of hose is transported ahead of the subsequent floor.
  • one of the bottom flaps which must be superimposed to form the soil, to seize and fold.
  • One of the bottom flaps can be closed by running this bottom flap onto a fixed resistor and folding it over.
  • the second bottom flap must be folded down in the transport direction. For this purpose, this bottom flap must be moved faster than the hose piece for a short time.
  • the publication DE 1 278 211 shows chains that carries Umlege 1952. This chain is driven by a drive, wherein a cam is provided, which ensures different running speeds of the chain within a circuit.
  • the object of the present invention is therefore to propose a bagging machine in which the adaptation of the rotating parts to new bag formats can be made easier and faster.
  • phase position of the rotatable part is adjustable to Bodenmacherzylinder during operation of the bag machine. In this way it is avoided to put the bag machine down for the purpose of format change. Furthermore, the rotatable part no longer needs to be replaced in a format change. A format change can thus be done much faster.
  • the movement of the Bodenmacherzylinders and the rotatable member are mechanically coupled and in the bag machine, at least one differential is provided with which the adjustment of the phase position is made.
  • the part that drives the rotatable parts can be rotated relative to the drive of the bottoming cylinder. This can be done for example mechanically, but also by means of a servomotor.
  • different drives are provided for the Bodenmacherzylinder and the rotatable part.
  • the adjustment of the phase position between the Bodenmacherzylinder and the rotatable part can be vorrisebar via a different control of the drives.
  • the use of gear means is avoided, whereby the susceptibility to wear of the bag machine is significantly reduced.
  • FIG. 1 shows a sketched side view of a bag machine 135. This figure has been added to show the technical background of the devices according to the invention. This is primarily to the description of the core function of such a bag machine, which consists in the field of tube section formation and soil preparation. For this purpose, it is again noted at this point that the Bodenmacherzylinder and the Bodenöffner are also explained in the German Auslegeschriften 1611699 and 1080846.
  • the in FIG. 1 The bag machine shown is fed to a paper web 100 from right to left in the transport direction of the paper web or the bag components z. In the hose forming station 101, which comprises the rollers 102, which also guide the conveyor belt 103, the paper web is folded into a tube 130.
  • the finished paper tube 130 is fed to the tear-off unit 131.
  • the feed rollers 106 which guide the paper web and lock the paper webs between opposing opposing rollers.
  • the paper tube is perforated by the knife 108, which is locked to the rotating knife carrier 107, which guides the knife along the dashed line 107a.
  • the counter-pressure cylinder 109 forms an abutment. Two knives 108 are attached to the knife carrier 107, so that two cross-sections are formed on the tube web 130 during one revolution of the knife carrier 107.
  • the impression cylinder 109 performs during this time two revolutions.
  • the pre-perforated tube then enters the nip between the two tear-off cylinders 110, which run faster than the feed rollers 106.
  • the tube is torn at the perforation, which takes place between the knife 108 and the nip between the Abr strictlyzylindern 110.
  • the paper tube is now singulated into paper tube sections 112. These paper tube sections 112 are first transported by the transport rollers 111 on. They reach the longitudinal cutting station 105, in which a longitudinal section is introduced into the front end of the hose section between the two rollers 116, which is necessary for the subsequent bottoming.
  • the tube sections are supplied to the bottom opening station 114, which mainly consists of the bottom opener 113. This is where the floors are opened.
  • the aforementioned German Auslegeschrift 1611699 shows such a bottom opener.
  • the pieces of hose are fed to the bottom maker cylinder 115, which takes over these and at different processing stations, which are arranged around the Bodenmacherzylinder passes.
  • the first of these stations is the bottom folding and gluing station 117.
  • the individual elements of this station are shown only in outline and can be found in the cited references. In any case, they are known to the person skilled in the art.
  • the floors are fixed or pressed in the floor closing station.
  • FIG. 2 again shows a bag as it can be made in such a bag machine 135.
  • This bag 123 has gussets 122.
  • FIG. 3 shows a slightly more advanced bag 121 with carrying handles 124, which have been additionally fixed with a cover sheet 125 to the bag.
  • Carrying handles and the methods and apparatus for their preparation and attachment to the bag are known in the art and are used for example in the DE 42 05 062 A1 , which was already mentioned at the beginning, shown.
  • such carrying handle stations form components of the bag machine which are downstream of the bottom maker cylinder.
  • the carrying handle station can also be arranged in front of the tube forming station.
  • FIG. 3 clarifies once again the design of the bag. So the width and height of the bag is shown again. The height H of the bag is determined by the length of tube section defined by the tear-off station.
  • the height of the bag or the tube section length is determined primarily by the diameter of the circumferential circle of the knife carrier 107.
  • the width B results from the width of the paper web and the settings of the hose station 101. Even with width changes extensive changes in the settings of the tools must be made, for example, on Bodenmacherzylinder.
  • FIG. 4 shows a detail 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. by virtue of the temporally 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.
