Definitions

  • the invention relates to a device for separating blanks from a stack with a magazine open at the bottom for receiving the stack, as well as a support device for the stack which can be moved back and forth on the underside of the stack and which rests against an underside of the stack between a starting position and a transfer position for the removed blank back and forth rotatable suction roller carries.
  • Such a device is known from EP-A-0 133 511, in which a magazine for receiving the stack is provided which has rollers on the underside which support the stack. The removal takes place via a suction roller movable by means of a crank mechanism. When a blank is removed, the rollers move along the underside of the stack, since they are coupled in terms of movement to the suction roller. The friction exerted on the blanks leads to the blanks being crumpled or the like, particularly at high removal speeds, as are common, for example, in cigarette packers. can be damaged.
  • the object of the invention is therefore to provide a device for separating blanks of the type mentioned, in which the risk of damage to the blanks is avoided.
  • the support device moves back and forth along a straight guide on the underside of the magazine, the movement of which is coupled to the rotary movement of the suction roller in such a way that the suction roller opposes the movement Direction of the carriage rolls on the underside of the stack, and on both sides of the suction roll each includes a belt section located in the plane of the bottom side of the magazine for supporting the stack on the underside, the length of which can be changed in accordance with the movement stroke of the carriage with smooth engagement with the underside of the stack.
  • Such a device is particularly suitable for soft, flexible, sheet-like blanks, in particular for outer paper blanks for soft cigarette packs.
  • no frictional force is exerted on the blanks, so that they cannot be pushed together and crumpled or damaged in any other way.
  • the device shown in FIGS. 1 to 3 comprises a magazine 2 carried by a stand 1 for receiving a stack of blanks 3 of packaging material.
  • the blanks 3 are in particular blanks for soft cigarette packs.
  • the blanks 3 can be removed at the lower open end of the magazine 2 by means of a suction roller 4 with a peripheral portion of a length that extends approximately over the length of a blank 3 in the removal direction and to a transfer device 5, only indicated schematically, for forwarding to a packaging station, such as it is described, for example, in EP-PS 0 133 511, can be transferred.
  • the suction roller 4 sits on a shaft 6, which is rotatably mounted in a carriage 7, extends through a slot in the stator 1 to the rear and carries there a pinion 8, which is in engagement with a rack 9 attached to the stator 1.
  • the carriage 7 can be moved back and forth in a direction parallel to the underside of the magazine 2 between two end positions along a guide 10 attached to the stand 1.
  • the drive for this takes place, for example via a rod 11 articulated on the carriage 7, which is articulated at its other end to a crank mechanism 12.
  • the pinion 8 is moved from the starting position shown in FIG. 1 into the transfer position shown in FIG. 2 and then back into the position shown in FIG shown starting position pivoted.
  • the shaft 6 is provided with a bore 13 that can be connected to a suction air source (not shown), from which suction air channels 14 lead to a section of the circumference of the suction roller 4 that is in the starting position of the suction roller 4 the underside of the bottom blank 3, guide.
  • a suction air source not shown
  • a belt 19 is fastened between two fastening elements 21 ', 21' on the stand 1 and guided around two deflection rollers 22 ', 22' in such a way that it is arranged essentially in a Z-shape.
  • the carriage 7 has two interrupted by a central recess 23, in a plane parallel to and below the bottom of the magazine 2 bearing surfaces 24 ', 24', wherein the suction roller 4 is in the recess 23.
  • the belt 19 extends from the fastening element 21 'adjacent to the starting position of the carriage 7 on the side facing away from the magazine 2 via the bearing surface 24' to an end of the bearing surface 24 'adjacent to the recess 23, carried by the carriage 7, projecting into the recess 23 Deflection roller 22 'to the further deflection roller 22' carried by the carriage 7, which is located at a greater distance from the magazine 2 and is offset from the fastening element 22 ', from there to the fastening element 22 ⁇ to be led.
  • the further belt 20 is attached on the one hand to the suction roller 4 and on the other hand to a fastening element 25 of the stand 1 and extends over the support surface 24 'of the slide 7 located therebetween.
  • the belt sections running over the support surfaces 24', 24 'of the slide 7 and the outer circumference the suction roller 4 in the area of the suction openings of the suction air channels 14 lie in a plane immediately below the underside of the magazine 2.
  • the belt 19 continuously engages the underside of the lowest blank 3 remaining in the magazine 2 by the carriage movement, while the belt 20 correspondingly continuously rotates around the circumference of the by rotating the suction roll 4 Suction roll 4 is wound so that the support of the stack of blanks 3 in the magazine 2 is progressively shifted from the belt 20 to the belt 19 until the latter supports practically the entire stack in the transfer position of the removed blank 3.
  • the belts 19, 20 are progressively placed on the underside of the lowermost blank 3 or moved away from it without any relative movement in the direction of movement of the carriage 7 between the belts 19, 20 and the blanks 3, and furthermore the lowermost blank 3 is also smoothly continuously removed from the underside of the stack in one unwinding process by the suction roller 4, there is no risk that the blanks 3 or the like by crumpling. to be damaged.
  • the belt 20 can also be a suction belt which can be acted upon by suction air by means of a suction device 26.
  • the operation is the same as in the previous embodiment. Only the belt 20 'is to be provided with a slot through which the blank 3 removed from the magazine 2 can be passed on to the transfer device 5 in the transfer position.
