Definitions

  • the invention relates to a floor laying device for cross bottom bags as shown in the preamble of claim 1.
  • transport belts which have at least components made of extremely tensile material such as steel.
  • these components of the belt are covered with a significantly more elastic, softer material, which is gentle on the transported objects.
  • so-called cable cord straps are to be mentioned, which contain in their core, which are usually covered with rubber.
  • conveyor belts of the type described have manufacturing tolerances. As a result of these manufacturing tolerances, there are again inaccuracies in the positioning of the bags in the processing positions and thus in manufacturing tolerances for the bags.
  • the object of the present invention is therefore to propose a device which limits the quality deficiencies of the bags caused by the manufacturing tolerances of the transport belt.
  • Angular velocity can be driven as the at least one
  • the present invention takes advantage of a number of surprising findings.
  • the transport process of the bags is initially determined by the tensile material.
  • the angular speed of the transport disks and the distance of the tensile material from the axis of the transport disks are thus decisive for the transport speed of the bags in the processing stations.
  • the latter size which is referred to below as the effective disk radius
  • the thickness of this layer is subject to fluctuations which are transferred to the effective radius of the transport discs and thus to the transport speed.
  • the measures according to the invention reduce the relative proportion of the fluctuations in the thickness of the more elastic, softer layer between the outer circumference of the transport disc and the material which can be subjected to tensile stress to the effective radius of the transport disc and thus to the transport speed.
  • a configuration is particularly preferred in which the ratio of the angular velocity of the drive disks to the angular velocity of the processing rollers is 2/3. This ratio of the angular speed of 2/3 also reduces the synchronism fluctuation of the transport belt by a factor of 2/3 compared to the case where the drive pulleys have the same angular speed as the processing rollers. It is advantageous to provide a drive system; which branches off torque for at least one drive pulley from a vertical shaft with the help of a bevel gear transmission and transmits it to the drive pulley via a reduction planetary gear.
  • Fig. 1 plan view of a section of an inventive
  • FIG. 2 Side view according to II-II in Fig. 1.
  • Fig. 3 Detailed view of the area encircled in Fig. 2.
  • Fig. 4 Detailed view of a transport belt.
  • Fig. 5 Gear configuration for driving the drive pulleys in a floor laying device according to the invention
  • Fig. 1 shows a section of a floor laying device according to the invention.
  • the tube pieces 1 are transported lying flat in the conveying direction x.
  • the bottom 2 of the tube pieces 1 has already been formed.
  • the formation of a bag bottom is described, for example, in another unpublished patent application by the same applicant with application number DE 102 55 483.
  • the piece of hose 1 is clamped between the conveyor belts 3.
  • the floor scoring station 30 and the glue station 31 are described below as an example of two processing stations present in a floor laying device.
  • the tools designed as creasing knives, which are fastened on the circumference of the creasing rollers 7 of the bottom creasing station 30, provide the bottoms 2 of the tube piece 1 with a bottom creasing, the counterpressure rollers 8 providing the counterforce.
  • a format-type adhesive application is carried out on the bottoms 2 of the tube pieces 1 by the format rollers 9.
  • the counter-pressure rollers 10 provide the necessary for the adhesive application Back pressure ready. All rollers 7, 8, 9, 10 are mounted in a machine frame, not shown, in a manner not shown.
  • the transport belt 3 is designed as an endless belt and wraps around deflection rollers at both ends of the floor-laying device.
  • the transport belts 3 are driven by the drive pulleys 4. These are driven by the vertical shaft 12 and driven by the gear 5 described in more detail with reference to FIG. 5.
  • a deflection pulley 6 is arranged on the right and left of each drive pulley 4, as can be seen in FIG. 2. These deflection disks 6 are rotatably supported in the machine frame via their bearing journals 11.
  • the speed of the transport belt 3 and thus the transport speed of the hose pieces 1 results from the distance traveled per unit of time.
  • the distance traveled depends, however, on the distance that the steel strand 13 of the transport belt 3 is from the axis of the drive pulley 4. 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 jacket 15 between the steel strand 13 and the surface 17 of the transport belt 3.
  • the surface 17 is in direct contact with the outer circumference of the drive pulley 5.
  • the thickness D is not a constant value but varies between the values D j m n and D ma ⁇ -
  • the distance D is subject to an error .DELTA.D resulting from the difference between D ma x and Dmin.
  • This error which results from the manufacturing tolerances of the conveyor belt, immediately causes synchronous fluctuations in the conveyor belt 3 and thus losses in the manufacturing quality of the cross-bottom bags.
  • Fig. 4 shows the structure of the conveyor belt 3 in a perspective view.
  • the transport belt 3 essentially consists of a plurality of steel strands 13 arranged in a horizontal plane and a rubber sheath 15 surrounding the steel strands 13.
  • the steel strands 13 Since the steel strands 13 have a considerably higher tensile strength than the rubber sheath 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.
  • Transport belts 3 with such a construction are referred to in the art as” cable cord belts "and can be kept narrow due to their tensile strength. This makes them particularly suitable for use in floor-laying devices with which cross-bottom bags with a small center-to-bottom dimension are to be produced. If transport belts with a lower specific tensile strength are used, they would have to be made wider in order to obtain a comparable tensile strength. The minimum floor center dimension that must be observed increases accordingly.
  • FIG. 5 shows a view of the transmission according to FIG. 1.
  • the drive torque is supplied to the transmission via the vertical shaft 12.
  • the shaft passes through a bevel gear 20, which takes up part of the torque and distributes it 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 it to a further 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, the support plates 19, 22 also being fixed to the support plates 18.
  • the Tragplatte ⁇ 18 are attached to the machine frame in a manner not shown.
