Definitions

  • the invention relates to a Bodenlegevorraum for accomplishracsoothe as shown in the preamble of claim 1.
  • transport belts which have at least components of extremely tensile material such as steel is recommended.
  • these components of the belt are covered with a much more elastic softer material, which protects the transported objects.
  • so-called Jardincortriemen be mentioned, which include in their core, which are usually coated with rubber.
  • the object of the present invention is to propose a device according to the preamble of claim 1 and a method according to the preamble of claim 4, which limits the caused by the manufacturing tolerances of the conveyor belt quality defects of the bags.
  • the present invention takes advantage of a number of surprising findings.
  • the transport process of the bags is first determined by the tensile material.
  • the angular velocity of the transport discs and the distance of the tensile material from the axis of the transport discs prevail.
  • the latter size hereinafter referred to as the effective disk radius
  • the thickness of this layer is subject to fluctuations, which are transmitted to the effective radius of the transport discs and thus to the transport speed.
  • a configuration in which the ratio of the angular velocity of the drive disks to the angular speed of the machining rollers is 2/3 is particularly preferred.
  • the ratio of the angular velocity of 2/3 the flutter of the conveyor belt also decreases by a factor of 2/3 as compared with the case that the drive pulleys have the same angular velocity as the processing rollers.
  • a drive system which, with the aid of a bevel gear, branches off torque for at least one drive disk from a vertical shaft and transmits it to the drive disk via a reduction planetary gear.
  • Fig. 1 shows a section of a Bodenlegevorraum invention.
  • the tube pieces 1 are transported lying flat in the conveying direction x.
  • the bottom 2 of the hose pieces 1 has already been formed.
  • the formation of a sack bottom is described, for example, in another unpublished patent application of the same Applicant with the reference number DE 102 55 483.
  • the piece of tubing 1 is clamped between the conveyor belt 3.
  • the Bodenrillstation 30 and the glue station 31 are described below.
  • the tools designed as creasing knives which are mounted on the circumference of the creasing rollers 7 of Bodenrillstation 30, provided the bottoms 2 of the hose piece 1 with a Bodenrillung, the counter-pressure rollers 8 provide the counterforce.
  • the transport belt 3 is formed as an endless belt and wraps at both ends of the ground-laying deflecting rollers.
  • the drive of the conveyor belt 3 is effected by the drive pulleys 4. These are driven by the king shaft 12 and driven by the transmission 5 described in detail with reference to FIG. 5.
  • each drive pulley 4 is arranged on the right and left each a deflection plate 6, as shown in FIG. 2 can be seen.
  • These deflecting disks 6 are rotatably supported by their bearing journals 11 in the machine frame.
  • the speed of the conveyor belt 3 and thus the transport speed of the hose pieces 1 results from the distance traveled per unit of time. However, the distance traveled depends on the distance from the steel wire 13 of the conveyor belt 3 to the axis of the drive pulley 4 occupies. This distance is referred to below as the effective radius R eff .
  • the effective radius R eff is the sum of the radius of the drive pulley 5 and the thickness D of the rubber sheath 15 between the steel strand 13 and the surface 17 of the conveyor belt 3.
  • the surface 17 is in direct contact with the outer periphery of the drive pulley 5.
  • the thickness D does not have a constant value but varies between the values D min and D max .
  • the distance D is subject to an error ⁇ D resulting from the difference of D max and D min .
  • This error which results from the manufacturing tolerances of the conveyor belt, causes immediate synchronization fluctuations of the conveyor belt 3 and thus losses in the production quality of the cross-bottom bags.
  • Fig. 4 shows the structure of the conveyor belt 3 in a perspective view.
  • the transport belt 3 consists essentially of a plurality of steel strands 13 arranged in a horizontal plane and a rubber jacket 15 surrounding the steel strands 13. Since the steel strands 13 have a substantially higher tensile strength compared to the rubber jacket 15, the steel strands 13 constitute the so-called "neutral phase of the transport belt 3. This means that the steel strands 13 can neither be compressed nor stretched. Conveyor belts 3 having such a structure are referred to in the art as “cable coring belts" and can be kept narrow due to their tensile strength.
  • FIG. 5 shows a view of the transmission according to FIG. 1.
  • the drive torque is supplied to the transmission via the king shaft 12.
  • the shaft passes through a bevel gear 20, which decreases a portion of the torque and distributed to the planetary gear 21 and the shaft 23.
  • the shaft 23 ends in a further bevel gear 20, which deflects the torque and delivers to another planetary gear 21.
  • Both planetary gears 21 each drive a drive pulley 4. All gear parts 20, 21, 23 are connected to the support plates 18 or the support plates 19, 22, wherein the support plates 19, 22 are also fixedly connected to the support plates 18.
  • the support plates 18 are attached to the machine frame in a manner not shown in detail.
