Definitions

  • the invention relates to a device for bulging Collar (13) on metal drums (10) with a Bulge device with a pressure roller (40), at least two support rollers (38, 39) and a holding device (21) for holding the metal drums (10) during bulging.
  • Beer and other beverages are supplied by the breweries etc. increasingly in so-called KEG barrels at restaurants and other major customers delivered.
  • the KEG barrels are Metal barrels made of stainless steel on their lower and Have a foot or head collar on the top. This Collars have one on their free faces tubular ring.
  • the KEG barrels on an operator Machine frame placed and rotatable here about its axis clamped.
  • the collar is then replaced by a radial pressure roller arranged on the inside and two radially on the outside arranged, interacting with the pressure roller Back-up rolls based on the principle of three-roll bending bulged.
  • the KEG barrel is rotating for this purpose driven.
  • EP 0 377 219 B1 Another device for denting metal drums describes EP 0 377 219 B1, which relates to FR 2 542 646 A1 refers.
  • the device after the FR 2 542 646 A1 perceived as disadvantageous that the KEG barrel must be driven in rotation, which is a separate Drive requires, as well as that the pressure roller obliquely is directed inside, mostly to the inside dented collar to be able to dent what the Device only suitable for KEG barrels with a high collar lets appear.
  • the device according to EP 0 377 219 B1 therefore leaves the principle of three-roller bending.
  • the barrel will also manually upright on a machine frame set and clamped.
  • the collar is then through a claw reaching into the collar bulged out by the Claw is pulled radially outwards.
  • An abutment The outside of the collar prevents it from closing is strongly pulled outwards.
  • the barrel always exactly with the lowest point of the bump through the Operator is set in the device. This does the bulge with this device accordingly complex.
  • a disadvantage of the devices both after the FR 2 542 646 A1 and EP 0 377 219 B1 is that the KEG barrels manually into the by an operator Devices or their machine frame are provided have to.
  • the devices according to the prior art can not be in a fully automatic system incorporate.
  • the respective bulge in the collar is exactly Claw must be positioned, making for one fully automatic operation additional monitoring organs would be required.
  • the invention is based on the problem of a Device of the type mentioned above to train that they are in a fully automated system can be incorporated.
  • the invention Device characterized by a conveyor, by which the metal drums can be transferred to the holding device are.
  • the invention leaves that through EP 0 377 219 B1 path and returns to the three-roller bend back.
  • the discharged from the bottling plant Metal drums are thus possibly over a Intermediate conveyor through the conveyor to the Pass holding device that takes over the metal barrel and positioned to dent. After denting you can hand the metal drums back to the conveyor and if necessary via a second intermediate conveyor again be sluiced back into the normal filling process.
  • the device according to the invention can thus be part a fully automated system. Manual Intervention by an operator is no longer necessary required.
  • the conveyor is preferably a turning device for assigned the metal barrels. This allows both Collar, namely the foot collar and the head collar bulge the device according to the invention. After one the collar has bulged, the metal barrel is on returned the conveyor, turned it over and then put it back on passed the holding device and finally bulged.
  • the conveyor itself can expediently be a roller conveyor seen in the conveying direction is preferably V-shaped.
  • the sponsor a magazine for temporarily storing metal drums and / or downstream. With a high volume of too Repairing barrels can be found in this magazine cached and then at a lower one Volume to be processed. The same can be done under Circumstances that have already been repaired may be appropriate store them in the filling plant.
  • Printing roller and the backup rollers on a roller guide stored, which in turn rotating around its axis is drivable, while the metal barrel in the Holding device is clamped.
  • Different from the The device according to FR 2 542 646 A1 is thus Metal drum silent while the roller guide with the Printing roller and the support rollers rotates. This gives a simpler design effort, because the rotating drive of the metal barrels on the model the FR 2 542 646 A1 large frictional forces between one Drive roller and the metal barrel are required. This In practice, friction forces can hardly be represented.
  • Fig. 1 shows a plant part of a filling plant for Metal drums, so-called KEG drums.
  • the empty ones Metal drums 10 are one by a feed conveyor 11 Barrel detection 12 supplied.
  • metal barrels 10 recognized with dented collar 13 and then computer-controlled on a subsequent switch 14 one Transfer intermediate conveyor 15. Not damaged Metal drums 10 pass the switch 14 on a by-pass conveyor 16 directly to barrel cleaning and Bottling line.
  • the metal drum 10 passes on the intermediate conveyor 15 a light barrier 17. This actuates a stopper 18, the possibly subsequent metal drums 10 stops.
  • the Metal drum 10 then passes into a turning device 19.
  • the metal drum 10 is in the turning device 19 tensioned, raised and then 90 ° with the damaged, bulging collar 13 forward filed again.
  • the metal barrel then reaches one Roller conveyor 20, the metal barrel 10 in the Area of a holding device 21 transported. Here the metal barrel 10 is gripped by the holding device 21 and excited and then in more detail later descriptively bulged.
  • the barrel After bulging the collar 13, the barrel is again from the holding device 21 on the roller conveyor 20 filed. Should the opposite collar 13 of the Metal barrel 10 damaged, the barrel will then rotated again by the turning device 19 by 180 ° and the denting process in the form described above fed. Are both collars 13 of a metal barrel 10 bulged, the barrel is turned by the turning device 19 90 ° in the upright position and by means of a Switch 22 to a second intermediate conveyor 23 postponed.
  • the repaired metal barrel 10 passes here a second light barrier 24, which the stopper 18th actuated so that a new metal barrel 10 to be repaired is released.
  • a further stopper may be provided, so that the intermediate conveyor 23, as well as the Intermediate conveyor 15 as a magazine for temporary storage of metal drums 10 can serve.
  • the roller conveyor 20 is V-shaped in cross section educated. It consists of two rows 25, 26 in each case V-shaped rollers 27, 28. The metal barrel 10 is thereby always exactly in the middle fed.
  • roller conveyor 20 is V-shaped in cross section is arranged in front of the turning device 19 Intermediate conveyor 15 and the intermediate conveyor 23 just are.
  • the metal barrels 10 namely in the area of Intermediate conveyor 15 and 23 transported upright, while being transported by the roller conveyor 20 lying down become.
