Definitions

  • the invention relates to a method for transporting prefabricated blanks for packs, in particular made of thin cardboard, preferably for the production of cigarette packs of the hinged box type, with stacked blanks delivered in boxes or similar containers, delivered, the boxes opened and the blank stacks of the latter be removed. Furthermore, the invention relates to a device for performing the method.
  • Transporting packaging material is an important problem with increasingly powerful packaging machines.
  • Such blanks are usually removed from the application site, e.g. B. manufactured in a paper mill and delivered in stacks. Most of these stacks of blanks are entered manually into magazines of the packaging machines. With the performance of these packaging machines is manual Considerable effort. This applies in particular if - as is known - the cut stacks are delivered to the place of use in larger boxes. It is now necessary to first open the box, then take out the stack of blanks to insert them into the magazines.
  • the object of the invention is to improve the handling and transport of stacks of blanks in the area of a system, preferably with several packaging machines, in such a way that only a slight manual use is required or can be dispensed with entirely.
  • Part of the invention is the use of special transport containers, namely cassettes, which are aligned with the size and shape of the stack of blanks. With the help of these cassettes, an exclusively mechanical transport of the blank stacks within the factory to the magazines of the packaging machines is possible.
  • the blank stacks are in the area a central distribution station ("station") received and reloaded onto the company-specific cassettes. If the blank stacks are received in closed boxes, these are opened in the distribution station for the removal of the blank stacks.
  • station central distribution station
  • the transfer of the stack of blanks from the supply containers, in particular from the cardboard boxes, into the cassettes and the transfer thereof to the transport device are also mechanized and automated.
  • the device according to the invention is characterized, inter alia, in that a cutting unit is provided for opening the cartons in the region of a side wall. Furthermore, a removal unit is provided for gripping the stack of blanks and for removing them. The stack of blanks can be inserted into the cassettes through the removal unit.
  • a special feature of the device according to the invention is that in the area of the distribution station the boxes with the cut stacks are mechanically opened on one side by cutting out a side wall from the box.
  • a cutting unit is used, which makes horizontal and vertical cuts on the edges of a side wall.
  • a removal unit grasps one, several or all of the blank stacks of the carton or a position of the blank stacks in the carton with clamp holders and pulls them out of the carton via the open side.
  • the removal unit can always be used when there is a gap between adjacent blank stacks for attaching clamping members.
  • the use of blanks for (cigarette) folding boxes is particularly advantageous. By default, these are designed such that an end region of the blank is designed to be relatively narrower, namely an inner tab of the lid. The stack of blanks thus have a laterally directed projection, in the area of which a stack of blanks with clamp holders can be gripped.
  • the cassettes for the transport of the blank stacks are designed so that the removal unit can transfer the blank stacks directly to the cassettes.
  • the stack of blanks is also removed in the unloading area possible from the cassettes with simple sliders.
  • FIG. 1 An embodiment of such a blank 10 is shown in FIG. 1.
  • the shape of the blank 10, which is common worldwide, is important for the functioning of parts of the device. This consists of a plurality of walls and folding tabs to form a box part 11 on the one hand and a cover 12 on the other.
  • the design of the parts of the lid 12 is of interest.
  • a lid front wall 13 is provided as an end part of the elongated blank 10 with an inner lid flap 14. In the finished hinged box, this is folded inwards, namely against the inside of the front cover 13 of the cover.
  • the inside cover 14 has a significantly smaller width than the blank 10 for the rest.
  • a stack of blanks 15 formed from such blanks 10 accordingly forms a projection on one side.
  • the stack of blanks 15 can be grasped by handling members which have clamping jaws for grasping the stacked lid inner tabs 14 one above the other.
  • the blanks 10 formed, for example, in the manner described are delivered as blanks 15.
  • Several, in the present case four, blank stacks 15 with, for example, 1000 blanks 10 each are accommodated in a closed carton 16. It is now a matter of removing the blank stacks 15 from the cartons 16 without manual use and feeding them to packaging machines (not shown).
  • a permanently installed conveyor device 17 is used for the mechanical transport of the blank stacks 15 within the system having a plurality of packaging machines.
  • This conveyor device is designed here as an overhead conveyor with a transport rail 18 running in a higher conveying plane.
  • Carriages, namely roller carriages 19, are movably mounted thereon, respectively with independent drive by a motor 20.
  • the roller carriages 19 are moved to the individual consumption points for the blanks 10, that is to say to the packaging machines.
  • the blank stacks 15 are transferred in a suitable manner to blank magazines on the machine.
  • the loading of the conveyor 17 takes place in the area of a distribution station 22.
  • the incoming cartons 16 are assembled with the blanks to carton stacks 23.
  • the cartons 16 are placed one after the other on the carton stacks 23 assigned feed conveyors 24, 25.
  • two cardboard stacks 23 are each assigned a feed conveyor track 24, 25. They consist of conventional roller conveyors known in conveyor technology, on which the cartons 16 can be conveyed in a sealed position or at a distance from one another.
  • the feed conveyor tracks 24, 25 lead to a distribution track 26. This is also designed as a roller conveyor. It runs below the conveyor 17 or the transport rail 18.
  • the feed conveyor tracks 24, 25 have a receiving leg 27, in the area of which the boxes 16 are placed.
  • the receiving leg 27 is directed transversely to the distribution track 26.
  • the receiving leg 27 runs over an arc into a transfer leg 28, running parallel to the distribution track 26 and directly next to it without any distance.
  • the workflow in the system according to FIG. 2 is such that the boxes placed on the feed conveyors 24, 25 are opened laterally in the area of a cutting station 29. This means that a side wall 30 is cut out of the carton 16. The projections of the blank stacks 15 formed by the inner lid flaps 14 are located in the region of this open side wall 30.
  • the open cartons 16 then go to a removal station 31.
  • the cut stacks 15 are removed via the open side wall 30 when the carton 16 is at a standstill.
  • all (four) blank stacks 15 are removed together and transferred directly into special transport containers, namely cassettes 32, during the removal movement.
  • the carton 16 on the feed conveyor track 24, 25 and the cassette 32 on the distribution track 26 lie directly opposite one another and aligned.
  • the cassettes 32 with the cut stacks 15 are then transported a little on the distribution track 16, in the direction of the arrow 33.
  • the cassettes then reach the area of one of several successive lifting stations 34.
  • Each of these lifting stations 34 is equipped with a vertical conveyor 35.
  • This consists of a movable on a vertical column 36 conveyor box 37 with a laterally projecting support frame 38 for a cassette 32.
