Definitions

  • the invention relates to a transfer device for gripping and depositing a filled bag from a hanging position on a filler neck onto a means of transport and for transferring it to a bag closing device, with a clamp arrangement with two approximately vertical arms articulated below, to which horizontal clamp strips are fastened, the Arms for clamping the sack flag by means of the clamping strips below the sack clamps on the filler neck can be moved with their free ends in the sense of closing the clamping strips and the arms can take up the means of transport running between them in the direction of the opening edge of a sack, and with a linear drive unit for moving the terminal arrangement in the running direction of the means of transport.
  • Sacks filled on a filler neck in the attached position are usually dropped onto a conveyor belt passing under the filler neck by releasing the bag clamps on the filler neck or gripped, placed on the conveyor belt and released there. Its opening is then spread by spreaders which engage in it from above. The bags are then transferred to a closing device with the bag flag spread by the spreaders above the product level.
  • the bags are at least partially out of control. This can result in the sacks being placed crookedly on the conveyor belt and, in deviation from their predetermined side folds, being spread and sealed. It can even lead to bags that are filled with a highly air-enriched filling material falling over on the conveyor belt after being released. This applies both to flat sacks and to gusseted sacks where the gussets can open in the area of the bag opening.
  • a transfer device of the type mentioned in which to lower a filled sack from its attached position to a filler neck, the latter is lowered overall by means of height adjustment means and so the sack is first placed on a grate. After the clamp assembly has been closed, this grate is lowered until the bottom of the sack is placed on a trolley to which the clamp device is attached.
  • the height adjustment of the filler neck requires flexible feed means for the neck. The lowering of the grate leads to a tensile load on the sack edges already closed by the clamp arrangement.
  • the present invention is based on the object of providing a transfer device with which bags attached to the filler neck, in particular already spread there, are transferred to the bag closing device under the greatest possible control.
  • the solution for this consists in a transfer device which is characterized by a lifting unit for the terminal arrangement in order to place the sack clamped between the terminal strips on the transport means, the actuating means for the terminal arrangement, the drive unit and the lifting unit are arranged under the transport means, which is designed as a conveyor belt.
  • the terminal arrangement is designated 100, the drive unit 200 and the lifting unit 300. Identical parts are provided with the same reference numbers in the figures, without being addressed several times in each case.
  • FIG. 1 shows an essentially U-shaped holder 1, in which vertical arms 2 can be pivoted about first axes of rotation 3. At the upper end head pieces 4 are pivotally attached, on which terminal strips 5 are attached.
  • the lower ends of the levers 2 are, as indicated only schematically here, connected to one another via a coupling 30.
  • a conveyor belt F is indicated by dashed lines. Above that, a filler neck S is indicated with dashed lines.
  • a drive cylinder 11 is provided in a middle position.
  • the rails 10 are placed at their ends on tabs 12 on a lifting device.
  • This essentially comprises an upper plate 13, a lower plate 14 and intersecting levers 33, 34 which are mounted in axes 15, 16 in these plates and are supported at their other ends by rollers 35, 36 on the plates which in axes 17th , 18 are mounted in the levers 33, 34.
  • Lift cylinders 19 are placed vertically on the top plate 13. The plates move apart when actuated.
  • the axes 3 and 7, which are mounted in the frame 1, are indicated, which represent the pivot points for the arm 2 and the handlebar lever 6.
  • the axis of rotation 21 for the head piece which was not previously discussed in detail, is attached.
  • 3 tabs 22 are attached to the handlebar, in which an axis of rotation 23 is held for parallel control of the head piece 4.
  • the multi-part terminal block 5 is attached to the head piece.
  • the substantially horizontal movement of the terminal strip when pivoting the lever 2 is shown with dashed lines. This prevents a pull on the sack surfaces from being exerted by a vertical movement component when the levers 2 and the clamping strips 5 are closed.
  • the U-shaped bracket 1 which has a rectangular cross section, is shown in three sections.
  • the right arm of the bracket is shown shortened, so that again the axes 3 and 7 for the arm 2 and the handlebar lever 6 can be seen, on which tabs 24 are also attached here.
  • the lower end of an arm with attached tabs 25 is shown in the left arm of the holder.
  • An actuating cylinder 27 acts on the first axis 26 of the arms.
  • Handlebar levers 29 are mounted in second axes 28 and move synchronously via a rotatable coupling member 30.
  • the lower part of the holder 1 can be seen on one of the guide pieces 9, which is axially displaceable on rods 10.
  • the rails 10 are protected on both sides by the guide pieces 9 with bellows 31.
  • the brackets 12 at the ends of the rails 10 are mounted on the upper plate 13 of the lifting device, of which the lower plate 14 and the pair of scissor levers 33, 34 can also be seen. These are mounted in axes 15, 16 and at the end have rollers 35, 36 mounted in axes 17, 18.
  • the actuating cylinders 19 bring about the stroke of the plate 13 with respect to the plate 14, the said scissor arrangement ensuring the parallelism of the plates.
  • End stops 38 for the holder 1 can be seen on central holders 37.
  • the drive cylinder 11 can be seen below this.
