Definitions

  • the invention relates to a device for transporting material webs of packaging material, the material web having lateral recesses, depressions and / or openings arranged at regular intervals from one another, with an endless conveyor, in particular with at least one conveyor drum, for transporting the material web, with on the top of the Continuous conveyor arranged increases or projections, namely first increases in the area of one side edge of the material web and second increases in the area of the other side edge of the material web, the material web (10, 35) abutting the endless conveyor during transport, such that the increases in the Enter depressions, recesses and / or openings.
  • Such a device is known from US-A-4 625 902.
  • the material web is transported by frictional contact of a lateral surface of a transport roller.
  • the circumferential length of the lateral surface is slightly larger than the length of one or more blanks.
  • the material web is thus transported slightly faster than is necessary for feeding to a processing station.
  • the frictional engagement between the material web and the outer surface is interrupted by lifting pressure rollers. This delays the material web while the transport roller continues to rotate. In this way, protrusions of the transport roller rest against the front edges of the recesses in the material web, so that the material web is positioned for processing in the processing station. Through this measure, one that occurs due to the frictional transport Slip balanced.
  • the elevations hit the front edges of the recesses in the material web, which can damage them.
  • the invention has for its object to enable a positionally correct transport of material webs of the type mentioned without additional measures and with gentle handling of the material web.
  • the endless conveyor is precisely adapted for the transport of material webs from blanks for hinged boxes. Since characteristic projections and depressions are formed on both sides of a material web formed from them due to the design of blanks for folding boxes, the endless conveyor, in particular the conveyor drum, is designed according to the invention with lateral edge elevations which correspond exactly to the contour of the material web. The elevations are thus always in positive engagement with the recesses in the material web, so that it is constantly transported in the correct position.
  • This design of the conveyor drum enables the same to be used in the formation of zigzag-shaped formations of a material web from blanks for folding boxes, for example to form a temporary store.
  • two interacting drums are provided according to the invention, which transport the material web in the correct position and which have suction elements arranged offset from one another and these act alternately on one and the other side of the successive cuts, such that the material web zigzag through the interplay of the suction elements. Is folded zigzag.
  • the present exemplary embodiment relates to the handling of material webs 10 from blanks 11 for hinged boxes or hinge-lid packs for holding cigarettes.
  • the elongated, approximately rectangular blanks 11 are oriented transversely within the material web.
  • the blanks 11 for hinged boxes have a characteristic structure.
  • An elongated center piece 12 consists at one end (edge of the material web 10) of a front wall 13 and opposite from a cover front wall 14 with a cover inner tab 15 arranged on the free edge thereof.
  • the center piece 12 is - except in the area of the cover - Inner flap 15 - provided with side flaps.
  • side flaps 16, 17 in the region of the front wall 13 and lid side flaps 18, 19 on the opposite side of the blank 11 are of interest.

  • the blanks 11 are provided with longitudinal and transverse punchings in the area of the side folding tabs.
  • the blanks 11 are therefore almost completely finished. Only in a central area are the blanks 11 connected to one another via material webs 24 as residual connections to be separated, forming the material web 10.
  • the special shape of the blanks 11 results in a material web 10 with special contours on the two longitudinal edges.
  • the blanks 11 form trapezoidal depressions 25 which are delimited by triangular or tapered projections 26.
  • a triangular depression 27 is formed between adjacent blanks 11 with limbs delimited by the inner lid lugs 15.
  • conveying members are provided with projections which fit into the recesses 25 and 27 in a suitable and form-fitting manner.
  • the material web 10 is transported on the circumference of a conveyor drum 28.
  • This is provided on the one hand with trapezoidal elevations 29 and on the opposite with the recess 27 corresponding in shape and size to elevations 30.
  • the elevations 29 form a continuous edge elevation 31 on one side of the conveyor drum 28. With the inside contour, this continuously delimits the material web 10 in the entire area of the system on the circumference of the conveyor drum 28.
  • the material web 10 is between the elevations 29, 30, that is to say both sides of the conveyor drum 28, exactly positioned.
  • the elevations 29, 30 enter and leave the depressions 25, 27 is lightened out and mechanical loads on the material web 10 are avoided, the elevations 29, 30 and also the edge elevation 31 in the areas facing the material web 10 are provided with inclined side surfaces 33, 34.
  • the elevations in question converge towards the free outside, that is to say with a decreasing cross section.
  • the conveyor for the material web 10, in particular the conveyor drum 28, can also be designed so that several, for. B. two material webs 10, 35 are transported side by side. If the blanks 11 are aligned in the same direction within the two material webs 10, 35, there is an edge formation of the conveyor drum 28 in the manner already described.
  • form-fitting guiding or adjusting members are arranged in the area between the material webs 10 and 35, that is to say in the middle of the conveying drum 28. that enter into a correspondingly designed, V-shaped recess 37 between the two material webs 10 and 35 in a form-fitting manner.
  • the recess 37 results in the area of the inner lid lugs 15, delimited by the beveled edges 20..23.
  • the two material webs 10, 35 are separated from one another in the longitudinal direction by a longitudinal cut 38.
  • the conveyor drum 28 need not be designed with a full cylindrical outer surface.
  • the conveyor drum 28 can have grooves 39, 40, 41 running in the circumferential direction. Between these, support disks 42, 43 are formed in the central area, which are cylindrical and form corresponding contact surfaces for the material web 10.
  • the one groove 39 on the edge is delimited on the outside by a drum disk 32, on the cylindrical circumference of which the elevations 30 are arranged.
  • the opposite groove 41 on the edge is delimited by the edge elevation 31.
  • conveyor belts 44 and 45 enter the grooves 39..41 with their ends, namely with deflection rollers 46, and take over the material web 10, 35.
  • strip-shaped, fixed deflectors 47 are in the region of the transition from the conveyor drum 28 to the conveyor belts 44, 45 arranged. The deflectors 47 enter the grooves 39..41 at one end.
  • three adjacent conveyor belts 44 are provided for the removal of the material web 10, 35 in accordance with the number of grooves 39..41.
  • the device described is particularly suitable for forming a zigzag-shaped formation 48 of the material web 10, 35.
  • This formation 48 can serve as a material store, since a large supply of blanks 11 can be accommodated in a small space.
