Definitions

  • the invention relates to a device for storing from on a transport device with a first one Speed in a row and spaced apart promoted tabular goods the preamble of claim 1.
  • Such a device is from DE 41 19 511 A1 known. It is used for handling paper or cardboard sheets suggested.
  • Transport and storage devices are, for example used in sheet dryer to ensure their continuous operation.
  • the ones coming from the sheet dryer, before for example, painted metal sheets are by means of a transport device one behind the other at high speed from about 6,000 to 10,000 sheets per hour of a stacking device fed.
  • the Braking difficulties In the event of an abrupt braking the panels can be damaged, or there can be impressions of buffered or sprung Stop devices, mostly at the end of a stacking table are attached. It has already been proposed to be tabular Goods before reaching the storage position respectively before reaching a stacking table delay. To further prevent the following Blackboard collided with the one just braked, becomes one while retarding the panels Overlap or scale of the panels tried to achieve.
  • Such a device is in the not previously published Patent application AZ: P 43 14 760.7 der Applicant described.
  • the conveyor in the form of a conveyor belt formed, and the braking device is in the transport direction behind the conveyor and below whose transport level is arranged. After this the rear edge of a panel the conveyor left, it hits the braking device on and is delayed there. Meanwhile, the Front edge of the following still unbraked board overlap.
  • the delayed table is reduced Speed of a storage position fed to a stacking table and stored there.
  • the invention is therefore based on the object a storage device of the type described Way of creating at high speed promoted tabular goods targeted and damage-free can be filed.
  • the device according to the invention enables non-contact Overlap or scale of the to be put down.
  • the one from the first transport facility conveyed boards are supported by the conveyor, which essentially changes with speed relocated the transport device, added and sucked in. If a drop position is above the braking device is reached, the negative pressure removed from the intake openings.
  • the looked at Blackboard falls down and hits one Braking device on where it is decelerated. While this deceleration process pushes the leading edge the following, sucked in by the conveyor Blackboard across the rear edge of the braked Blackboard. Characterized in that the subsequent from the conveyor sucked panel at a distance from the Braking level is maintained, the front collides Edge of the table below with the top the braked board safely prevented.
  • the conveyor could be coupled together plate-shaped areas; it has however, proved to be advantageous as a conveyor to use a suction belt.
  • the compliant material of a belt lies well against the surface tabular goods, so that a full surface support and thus ensures effective suction is.
  • a preferred device is below the Conveyor and preferably essentially parallel to this the braking device in the form of a Impact area provided. After reaching a drop position and turning off the suction drops the looking down at the impact surface, in which preferably at least one can be subjected to negative pressure Intake opening is integrated.
  • the impact surface is a displaceable conveying surface is.
  • the conveying area could be constant and opposite the above arranged conveyor less Speed are driven. It can also recommend using the conveying area essentially speed corresponding to the first speed to drive, so that of the conveyor discarded board first with the same Speed conveyed in the direction of transport until the braking process begins.
  • the tablet will preferably braked in a rear area. Therefor it is possible to use a controller for controlled loading the intake opening of the brake device to be provided with negative pressure.
  • the relocatable funding area to be trained to be essentially the first Speed can be driven at the appropriate speed is and from this speed to one second speed decelerated or from the second speed to that of the first speed corresponding speed can be accelerated is.
  • One dropped by the conveyor Blackboard can then be done with essentially the same Transport speed from the relocatable conveyor area take over and suck against them. So can by braking the conveying surface at the same time indistinctly sucked board can be delayed. With such a braking device, the Braking process with high reproducibility and extreme adjust exactly. All you have to do is speed the shiftable conveying area can be controlled.
  • the relocatable conveyor area to use a suction belt.
  • a resilient stop element provided as a limitation of the storage position.
  • a magnet arrangement for controlled holding of the goods includes and that the braking device below the conveyor or the transport level provided is.
  • the magnet arrangement can be used for this controllable electromagnet or one with a repulsion element interacting permanent magnets include.
  • FIG. 1 a side view of an inventive Device for depositing tabular goods.
  • the figure shows an overall reference number 2 designated stacking device for storing high Speed on a transport device 4 delivered sheet metal plates 6.
  • the device 2 comprises a conveyor device 8, a braking device 10, and a stacking table 12 by a resilient Stop element 14 is limited.
  • the conveyor 8 is from a suction belt 16 educated. There are suction openings 18 in the suction belt 16 provided that in communication via a suction space 20 with a vacuum generating device 22 stand.
  • the second suction belt 32 can be accelerated and decelerated and is one of the conveyor when it hits 8 discarded sheet of metal preferably in driven essentially the same speed like the conveyor 8.
  • the hitting metal sheet is sucked against the suction belt 32 and in the direction transported to the stacking table 12.
  • the speed of the Suction belt 32 and the sucked sheet metal through a controller 38 and a drive device 40 of the Suction belt 32 reduced.
  • Suction belt 32 is preferred only braked when the metal sheet only with a rear area on the suction belt 32 is liable.
  • the front pushes Area 42 of the subsequent metal sheet over the Trailing edge of the braked sheet. Because the following table but at a distance above the braked board is held, it can not The panels come into contact and are damaged.
  • a blower device 46 Nozzle 48 provided Immediately in front of the stacking table 12 and below the Level of the conveyor surface 30 or the second suction belt 32 is one which interacts with a blower device 46 Nozzle 48 provided.
  • the nozzle 48 is in the transport direction directed.
  • the blower device 46 can be placed between the top of the stack Blackboard and the following blackboard an air cushion blow in. This can prevent that the front edge of the following table on the Stack surface hits and damaged. Far away through the nozzle effect of the rear end area the board to be put down is pulled down.
  • the Chalkboard is placed on the stack accelerated and it cannot cause collisions with the table below come.
