Definitions
- the invention relates to a method for stacking of shingled sheets, especially Cardboard sheets according to the preamble of Claim 1 and a device for performing of the method according to the preamble of claim 5.
- DE-C 38 23 806 discloses a stacking device with an auxiliary stacking platform designed as a bar grate, on which the sheets are stacked until a new pallet has been placed on the storage platform and lifted under the bar grate .
- the bar grate can be arranged vertically fixed at a certain distance below the feed level, since - unlike sensitive paper sheets - these can fall freely over a longer distance without having to be stacked Problems occur.
- a stack change can be carried out while the partial stack formed on the bar grate grows up to the level of the feed level.
- a disadvantage of the generic method and devices is that for retracting the bar grate a gap in the scale flow of the supplied Sheets must be created.
- the staffs of the Bar grates cannot be covered over the entire Move stacks if sheets continue to be fed will.
- the weight of the on the bar grate partially resting when entering the stacking area Arches rises constantly, so it especially on the last part of the driveway damage in front of the notice boards the sheet leading edges and malfunctions by turning the front edge of the sheet. According to the state of the art, this can only be prevented if, during the retraction of the Bar grates in the stacking area of the sheet feeder is temporarily interrupted. To do this, arches are rejected, but not as a committee are more usable.
- the invention is based on the object generic method and a generic To improve the device so that a stack change done without loss of arches can be.
- the cyclical retraction of the bar grate Claim 3 allows sensitive arches to yourself to pull straight again during downtime, to fold the leading edges of the sheet to prevent.
- According to claim 4 are in particular thin and delicate arches in the area between the bar tips of the bar grate and the leading edges of the sheet hanging downwards pushed up again. In this Position pull yourself back by shaking straight.
- the dependent claim 6 contains a constructive particularly advantageous embodiment of a Apparatus according to claim 5.
- the low-friction Coating of the bulletin board according to claim 7 ensures that the range between the rod tips of the bar grate and the bulletin board leading edges of the sheet hanging down for straightening the arches without resistance can move up.
- Figures 1 to 4 show roughly schematically in Side view of a device according to the invention and the procedure for changing the stack.
- Fig. 5 shows an enlarged view Longitudinal section in the direction of suction through the bulletin board with the vibrating device.
- FIG. 6 shows a section along the line A - B of Fig. 5.
- FIGS. 1 to 4 The schematically shown in Figures 1 to 4 Stacking device is used for storing continuously transported in a stream of shed Cardboard sheets 1 on a stack 2 in the connection to a cross cutting machine.
- the stack 2 is on a lifting and lowering storage platform educated; in this example a scissor lift table, placed on the pallets.
- the sheets 1 are from a belt conveyor 3rd fed to the stacking area, the outlet side Deflection rollers 4 as well as the ejection rollers 5 above the maximum stack height in the Storage rack are stored.
- transversely Message board extending across the working width 6, the vertically stationary in or against the direction of sheet travel adjustable to different format lengths is. Its structure is shown in more detail in FIGS. 5 and 6 shown.
- the bulletin board 6 extends vertically Direction from an area above the feed level to below the bar grate 7. In his lower part in the area of the rods 8 vertical recesses so that the tips of the Bars 8 - as indicated in Fig. 6 - by Message board 6 can be moved through, for. B. when filing short formats.
- Prefers is the notice board 6 over the working width in separate separate segments, so two or more stack 2 with different format lengths can be formed side by side at the same time can.
- the bulletin board 6 or its individual Segments are at the end of adjustment rods 9 attached, which is approximately at the level of the belt conveyor 4 in and slidable against the direction of sheet travel in the stacker frame are stored. It can be in a horizontal Vibration in and against the direction of sheet travel be transferred.
- the front part 10 of the Message boards 6 is on the sheet stop side low friction, e.g. B. coated with PTFE.
- the Damper elements 12 are arranged at two heights: On the one hand on the suspension on part 11, on the other hand approx. 100 mm lower, i.e. in the area between the suspension and the point of attack the vibrating device 13.
- the sheet longitudinal edges are not shown vertical side guide plates, those on both sides of the machine and each between the stacks 2 in the direction of sheet travel extend.
- a sensor 14 is located slightly below the feed level, the second sensor 15 approx. 40 mm above the bar grate 7.
- Fig. 1 the storage on the stack 2nd shown, which is formed on a pallet. Of the Bar grate 7 is located outside the stacking area in a waiting position. During the arches 1 are continuously fed, the storage platform continuously lowered to the head the sheets 1 towards the stack 2 constantly hold. Controlling the height of the top of the stack takes place by means of the sensor 14. When the stack 2 has reached the desired size, e.g. Legs certain number of sheets 1 has been deposited, the batch change is initiated. This will be done first the stack 2 up at high speed lowered to sensor 15, then the lowering movement slows down until the top edge of the stack approx. 50 mm below the rods 8 of the Bar grate 7 is located (Fig. 2).
- the sheets will be 1 continue to be funded continuously, with by quickly lowering the stack 2 the Fan the rear edges of the supplied sheets 1, so that the rod grate 7 retract between them can.
- the retraction of the bar grate 7 is triggered as soon as the top of the stack is up located under it.
- there is a shaking motion of the front part 10 of the bulletin board 6 triggered by the eccentric elements of the vibrating device 13 is rotated.
- the shaking motion will be on the bar grate 7 forming partial stacks in a horizontal vibration offset in and against the direction of sheet travel. It has been shown that there is a suitable vibration sets when hard damper elements 12 in the heights specified above be and the eccentric 14 with a frequency from 60 - 70 Hz.
- the bar grate 7 in a first step with a Speed from approx. 120 mm / s to approx. 50% - 75% of the format length moved into the stacking area (Fig. 3). Meanwhile, the trailing edges of the sheets supplied below 1 placed on it. By shaking the one on it formed sub-stack, the friction is reduced, so that the bar grate 7 without compression or Damage to the sheets 1 can be retracted. After The rod grate becomes the continuous running-in phase 7 moved in cycles, the standstill and Travel cycles are set depending on the format. It has been shown that by the cyclical movement the rod grate 7 this easily between the leading edges of the sheet growing on it Partial stack 9 can be moved.
- the bar grate 7 is then opened moved back the stacking area so that the Part of the pallet is transferred. Once the Stack 2 reaches the height of the upper sensor 15 the storage platform will be accordingly the increase in height of the stack 2 continuously lowered. The stack 2 has the desired size reached, a stack change to the performed as described above.
