Definitions

  • the invention relates to a front table on vascular treatment machines, preferably on vascular or bottle filling machines, and in this case specifically to a front table according to the preamble of claim 1.
  • vascular treatment machines such as e.g. Filling machines, capping machines and labeling machines to provide a so-called front table or a machine area with transport elements, via which the vessels to be treated or processed are fed to the treatment station having the treatment organs of the machine or removed from this station after the treatment and removed from the machine .
  • the front table thus forms the actual vessel inlet and the vessel outlet of the entire machine consisting of the front table and treatment station, at least two transport elements being provided on the front table for the vessel flow, one of which is used to convey the vessels to the treatment station at a predetermined machine distance or division distance by means of a conveyor belt and inlet screw feeds the vascular treatment machine and one removes the treated vessels from the treatment station and thus from the vascular treatment machine.
  • the front table then has at least three transport elements, namely in turn one for feeding the vessels to be filled to the vessel or bottle filling station, one in the form of a transfer element for removing the filled vessels or bottles from the vessel or bottle filling station and for transferring them to the sealing station and to a conveyor belt for removing the sealed containers or bottles from the sealing station and for transferring them, for example, to a subsequent conveyor belt which removes the containers or bottles.
  • the above-mentioned transport elements of the front table are each designed as transport stars, each of which has several circumferentially open and evenly spaced at its circumference Has recesses (pockets) for receiving vessels.
  • the vessels received by the recesses of the transport stars are each moved on a part-circular conveyor line by the transport stars.
  • a securing element is also provided on the part-circular conveyor section of each transport star, which encloses the relevant transport star on its part-circular conveyor section between the transport star inlet and the transport star outlet, the transport star inlet beginning and the transport star outlet the end the part-circular conveyor line.
  • these securing elements are outer guide railings or guide curves, each of which forms a stationary guide surface for the vessels which surrounds the relevant transport star on the part-circular conveyor path.
  • the distance between the guide surface and the axis of rotation of the respective transport star must be adapted to the diameter of the vessels arranged upright in the recesses of the transport stars.
  • FIG. 1 Also known is a front table of the type mentioned at the beginning (US Pat. No. 3,957,145), which (front table) has a transport star at the vessel inlet and at the vessel outlet, the associated securing element of which is not a guide railing, but a free length of a band-shaped element, which as closed loop runs endlessly over rollers provided on the machine frame.
  • the invention has for its object to develop a front table of the type mentioned in such a way that while maintaining its basic advantages, as many vessels as possible in the transport path of the at least one transport star are kept free of play and safely even in the event of gaps in the vessel flow.
  • the band-shaped element which rotates synchronously with the transport star, presses the receptacles received by the transport star into the recesses of the transport star and holds them there.
  • the band-shaped element also acts here as a tensioning strap with which the vessels are clamped in the recesses of the transport star.
  • the required tensioning force is achieved by a tensioning device, preferably in cooperation with a certain intrinsic elasticity of the band-shaped element.
  • the band-shaped element serving as a securing element lies radially to the axis of rotation of the transport star opposite a circular-cylindrical circumferential surface of this transport star and is under the influence of the clamping force, the band-shaped element can be in the absence of vessels, i.e. If there are gaps in the flow of the vessel, place it against this peripheral surface of the transport star. Even if there are gaps in the flow of vessels, the invention does not lead to malfunctions, but also in this case the vessels in the recesses of the transport star are kept free of play.
  • this circular-cylindrical peripheral surface is designed such that the radius (radius) determining this peripheral surface is smaller than the radius determining the circular path of the conveying path of the transport star.
  • the peripheral surface is formed on a partial area of the transport star between its top and bottom, at which (partial area) the transport star has a diameter that is less than or at most equal to twice the distance that the closed side of the at least one recess facing the axis of rotation of the transport star of this axis of rotation.
  • This design has the advantage that the circular or cylindrical peripheral surface is not interrupted by the recesses of the transport star and is also between two sections of the transport star, where it has a larger diameter, so that even if gaps suddenly appear in the vessel flow and despite the occurring or possible short-term relaxation of the band-shaped element with its length runs perfectly onto the peripheral surface of the transport star.
  • the circular cylindrical peripheral surface is designed such that the radius determining this peripheral surface is equal to or greater than the radius determining the circular path of the conveying path of the transport star.
  • the band-shaped element runs freely over the rollers, i.e. a separate drive for the band-shaped element is not provided, but this is moved by the transport star by its abutment against the vessels or against the peripheral surface of the transport star. This always results in a synchronous movement of the band-shaped element with the transport star. In particular, a relative movement between the band-shaped element and the vessels is also avoided, so that these are free of vibrations due to their clamping in the transport star and due to the lack of a relative movement between the vessels and the band-shaped element even without their own movement, i.e. can be transported around their high axes without turning. The clamping of the vessels also results in a quiet or low-noise run for the front table. However, it is also within the scope of the invention to drive the band-shaped element from the machine.
  • the design is such that a roller, preferably serving as a deflection roller, is provided in the area of the transport star inlet and in the area of the transport star outlet in such a way that the axes of rotation of these rollers are at a radial distance from the axis of rotation of the transport star such that at the transport star inlet and at the transport star outlet, the respective partial length of the band-shaped element lying against the roller there and facing the transport star has a radial distance from the axis of rotation of the transport star, which ensures that the vessels, in particular also the vessels with the largest diameter to be processed, are free of faults on Transport star inlet can be inserted into the recesses or removed from the recesses at the transport star outlet. It is then not necessary to adjust these roles provided at the transport star inlet and at the transport star outlet to different vessel sizes.
  • the star on its partially circular conveying path is replaced by a free one
  • the length of the at least one band-shaped element is enclosed, ie the band-shaped element is not guided over rollers over this arcuate length.
  • the free length of the at least one band-shaped element forming the securing element encloses the associated transport star over an angular range greater than 90 ° , preferably over an angular range of 180 ° , ie preferably over an angular range which is also somewhat larger than the part-circular conveyor path of the transport star, so that the vessels, regardless of their respective diameter, are firmly clamped on the transport star by the length of the band-shaped element.
  • the front table has an inlet area 1 on a bottle treatment machine, which otherwise has a filling station and a closing station and is not shown in detail, at which the bottles 2 are conveyed by a conveyor, e.g. via a conveyor belt 3 in the direction of arrow A, i.e. 1, the front table and thus the bottle treatment machine are fed from the left, and an outlet area 4, at which the closed bottles 2 after the treatment (e.g. filling) from the front table to a transporter, e.g. be transferred to a conveyor belt for removing the bottles 2 in the direction of arrow B.
