Definitions

  • the invention relates to a method for removing the jute wrapper from a rectangular tobacco bale.
  • the invention also relates to a device for removing the jute casing from a right-angled tobacco bale transported on a horizontal conveyor.
  • the invention is based on the object of further improving a method or a device of the type described at the outset.
  • the jute wrapping is cut through at least two mutually parallel sides of the tobacco bale by a horizontal longitudinal section and on a third side of the tobacco bale by a cross section intersecting the longitudinal section and is released from the tobacco bale by lifting and dropping the tobacco bale.
  • the longitudinal section is made through three sides of the tobacco bale extending perpendicularly to the conveying plane and the cross section through the third side of the tobacco bale running transversely to the parallel sides.
  • the longitudinal section is made through two sides of the tobacco bale that extend perpendicular to the conveying plane and parallel to one another, and the cross section is essentially through a third side of the tobacco bale that is parallel to the conveying plane.
  • opening the jute wrapping is made even easier by the fact that the longitudinal cut is made in a height section of the tobacco bale that is close to the conveying plane.
  • a procedural simplification results from the fact that the longitudinal cut is produced by the longitudinal transport of the tobacco bale relative to an adjustable cutting device. It is also expedient if the cross section is produced in a stop position of the tobacco bale placed between the longitudinal transport and a transverse transport.
  • the transport movement of the tobacco bale is additionally integrated into the cutting process in that the cross section is produced by the transverse transport of the tobacco bale relative to a stationary cutting device.
  • a modified procedure for producing the longitudinal section consists in that the longitudinal section is produced in a stop position of the tobacco bale placed in the longitudinal transport.
  • the device for carrying out the method described at the outset consists in that the horizontal conveyor has a horizontally oriented cutting means for at least two parallel long sides of the tobacco bale and a vertically oriented cutting means for a transverse third side, and a pulling means interacting with a lifting means for the tobacco bale on the top of the tobacco bale assigned for the jute wrapping.
  • a preferred embodiment consists in that the horizontal cutting means each consist of a circular knife which can be set against the longitudinal sides of the horizontal conveyor and the vertical cutting means consists of a circular knife which can be moved vertically transversely to the conveying direction of the horizontal conveyor.
  • a variant of the invention which produces a modified cutting profile consists in that the horizontal cutting means consists of two circular knives positioned on both longitudinal sides of the horizontal conveyor and the vertical cutting means consists of a circular knife positioned in a direction of advance of the tobacco bale running transverse to the conveying direction of the horizontal conveyor.
  • the opening of the severed jute wrapping is made considerably easier in that the horizontal cutting means is arranged in a height section of the tobacco bale which is close to the horizontal conveyor.
  • the horizontal cutting means is arranged on an angle lever which can be pivoted about a fixed axis.
  • a variant of the invention is that the horizontal cutting means are arranged on pivotable angle levers arranged on both sides of the horizontal conveyor, the pivot axes of which can be moved longitudinally relative to the horizontal conveyor.
  • the sliced jute covering can be pulled off in a single operation in that the pulling means has a needle gripper integrated into a pair of clamp grippers of the lifting gripping means.
  • Undressing the tobacco bale in a manner according to the invention represents a considerable simplification of the method, which can be achieved with a significantly lower construction cost of the device, since the transport movement of the tobacco bale through the cutting and pulling station is included to make the separating cuts.
  • the device for cutting and removing a jute wrapping 1 from oriental tobacco bales 2 has horizontal conveying means in the form of tobacco bales 2 in opposite conveying directions 3 or 4 conveying belts 6, 7 and one the tobacco bales 2 in the direction of arrow 8 from the conveying belt 6 on the conveyor belt 7 transferring cross conveyor in the form of a transport plunger 9 and a transfer table 11.
  • the conveyor belt 6 is assigned a pressure belt 12 running at the same speed and acting on the tobacco bales 2 and indicated by dash-dotted lines.
  • a lifting gripping means 23 for the wrapped tobacco bales 2 which have a drive 27 for gripping and releasing the tobacco bale 2 and a drive 28 are equipped for lifting the tobacco bale 2, a needle gripper 29 for gripping the jute casing 1 being additionally integrated in the lifting gripping means 23. 31 with a storage table for the jute wrapper 1 is designated.
  • a wrapped tobacco bale 2 is on the conveyor belt conveyed non-positively under pressure by the pressure belt 12, where it first meets the end face of the circular knife 14 projecting into the conveying path, which swings back elastically laterally about its axis 19 and thereby first executes a horizontal longitudinal section 32 through the jute wrapping 1 over half the end face of the tobacco bale 2 .
  • the circular knife 14 strikes the long side thereof, over the full length of which the longitudinal cut is completed.
  • the same process is repeated for the other half of the leading end face and long side of the tobacco bale 2 by means of the offset circular knife 13. In this way, a continuous horizontal cut is achieved over one end face and two parallel long sides.
  • a vertical section 34 through the jute wrapper that crosses the horizontal section 32 on the end face of the tobacco bale is produced in a holding position of the tobacco bale 2 determined by a stop 33 at the end of the conveyor belt 6.
  • the tobacco bale 2 with the severed jute wrapping 1 is transferred through the ram 9 over the table 11 onto the conveyor belt 7, where, according to FIGS. 2a to 2d, the clamp grippers 24, 26 grip the tobacco bale 2, lift it and drop it by subsequent opening, so that it falls out of the underside of the jute casing 1, which opens along the horizontal section and is held in place by the needle gripper 29 of the lifting gripping means 23, which is seated from above.
  • the lifting gripping means 23 then moves on the portal 22 via the deposit table 31, where the jute wrapper 1 is deposited, while the bare tobacco bale 2 is removed in the opposite direction 4 by the conveyor belt 7.
  • the horizontal cut 32 is made here with a tobacco bale 102 stopped under a stationary punch 136 by means of the circular knives 113, 114 which can be moved relative to it, whose pivot axes 118 and 119 in this case on a carriage 137 and 138 along the stationary conveyor belt 106 can be moved from the position shown in solid lines to the position indicated by dash-dotted lines in the direction of arrows 139 and 141, respectively.
  • FIGS. 1 In FIGS.
  • the jute wrapper 201 opens to the sides from the center of the bale, as shown in FIGS. 6a to 6d, so that the bale can also fall out downwards.
