  • a targeted follow-up and adjustment the conveying process or the conveying device to the stack size is done by a control device. This controls the feed speed of the objects depending on the stroke position the conveyor.
  • the invention has for its object a device mentioned type to create continuous processing of flat packages of different training with a higher throughput than before. disorders double deductions are to be largely avoided.
  • the device according to the invention can be inclined in the Transport piles are placed and stacked for deduction be aligned vertically.
  • For vertically aligned packages is the smallest between these and double deductions can thus be avoided more reliably than before become.
  • the packages are preferably set up dynamic due to lifting movements of the conveyor and movements of endless means of transportation. A dynamic movement enables very quick erection and vertical positioning of the packages.
  • At least two sensors arranged one above the other are provided.
  • These sensors can be inexpensive and very reliable can be realized by push buttons.
  • the funding body and the endless means of transport for pressure equalization within of a stack can be moved relative to one another.
  • Such a Pressure equalization always takes place when using the means mentioned excessive pressure found in a stack to be peeled becomes.
  • the pressure equalization is preferably carried out by a corresponding lifting movement of the conveyor. The first one The shipping item of the stack is only deducted when pressure equalization has taken place. With such a pressure equalization can further increase the likelihood of double deductions can be reduced.
  • FIG. 1 shows an endless part Means of transport 1, which is preferably an endless belt with articulated interconnected sections 1a.
  • everybody Belt section 1a carries a driver 1b.
  • Carrier 1b becomes one open at the front and one at the top Transport compartment 7 formed, for example by hand
  • Transport compartment 7 formed, for example by hand
  • Stack 2 of several standing on the belt sections 1a flat objects, such as packages 2b and 2a is.
  • the transport direction is in Figure 1 by the arrow 12 indicated.
  • a vertical side wall only indicated here 26 is used to align the stacks 2.
  • the aligned stacks 2 slide on this side wall 26 in the direction of the arrow 12 along.
  • the stack 2 of packages placed in the compartments 7 2b are in the direction of arrow 12 against a conveyor 4 moves.
  • This device 4 is on a carriage 14 attached, the 15 in by means of a fixed-stroke actuator the directions of the double arrow 16 is movable in a stroke.
  • the Carriage 14 is slidably guided on a frame 8. The stroke can be limited by stops not shown here his.
  • the conveyor 4 has a conveyor 3, which is preferably an endless flexible trigger tape that is on Rollers 26 is mounted. In the drawing here is only one of the two rollers 26 shown.
  • the trigger belt 3 is preferred a vacuum belt and slides with its front run 3b ( Figure 3) along a vacuum shoe 25.
  • the driver 1b each have a recess 1c, which according to FIG formed corresponding to the contour of the conveyor 4 is. The driver 1b can thus via the conveyor 4 can be moved away.
  • buttons 5 and 6 are sensors and horizontally protrude from the in Figure 1 shown trigger level A. Both buttons 5, 6 are over the conveyor 3 and the lower button 6 at a distance below arranged by button 5.
  • the buttons 5, 6 are lever-like trained and operable independently.
  • the upper Button 5 is with a rotary encoder 9, preferably an absolute rotary encoder connected. This rotary encoder 9 measures the swivel position of the button 5 and according to FIG. 3 gives a corresponding one Signal via a signal line 18 (FIG. 3) to a control device 17 from.
  • the encoder 9 has a comparatively high Resolution on.
  • the position of the lower button 6 is determined via two initiators 10, which emit a corresponding signal via a line 30 to the control device 17.
  • the initiators 10 are activated according to FIG. 1 by a rear, angled arm 6a of the button 6.
  • the initiators 10 enable a cost-effective determination of the position of the lower button 6, this determination being less precise than that of the absolute rotary encoder 9.
  • a rotary encoder could also be used instead of initiators.
  • the two buttons 5 and 6 are attached to the carriage 14 and are moved with it in the directions of the double arrow 16.
  • Both pushbuttons 5 and 6 project in the rest position, each with a front end according to FIG. 1, the trigger level A and thus the strand 3a.
  • the positions of buttons 5 and 6 are a measure of the distances of buttons 5 and 6 from trigger level A.
  • the buttons 5, 6 are brought into their basic positions shown in FIG. 1 by tension springs. The operation of the device according to the invention is explained in more detail below.
  • FIG. 1 shows two filled transport compartments 7 with packages 2a, 2b.
  • the stacks 2 are transported with the means of transport 1 in FIG Arrow direction 12 moves.
  • the funding body 3 stands here quiet. With the movement of the stack 2 in the direction of the arrow 12 the frontmost shipping item 2a is brought into the withdrawal position, in which it is applied or sucked to the conveyor 3 and thereby frictionally for further transport this can be connected.
  • FIG. 4 shows the foremost shipping item 2a in the trigger position.
  • the foremost mailpiece 2a is aligned vertically and is located at a predetermined distance from the front run 3b of the conveying member 3.
  • the foremost mailpiece 2a is sucked onto the conveying member 3 and the conveying member is activated for transport.
  • the direction of withdrawal of the package 2a is indicated by the arrow 13 in FIG.
  • the stack 2 is set up dynamically according to FIGS. 5 to 7 and, if necessary, pressure equalization is created. If the stack 2 is vertical and not inclined forwards or backwards, it is of course not necessary to set it up.
  • FIG. 5 shows schematically a stack 2 which, as can be seen is inclined forward at its lower end.
  • the oncoming conveyor 4 becomes a foot end 2a 'of the foremost package 2a pressed according to Figure 5 on the lower button 6.
  • the lower button 6 is from stack 2 to its rear stop position deflected. Thereafter, the stack 2 through the opposite movements.
  • buttons 5 and 6 are pivoted accordingly. These positions of the two buttons 5 and 6 correspond essentially too high pressure in stack 2 and therefore one too high friction between adjacent packages 2a and 2b.
  • the drive is now via the control device 17 15 actuated so that the conveying device 4 according to FIG Arrow direction 22 is moved until the distance between the Package 2a and the front strand 3b, indicated by the Push button positions reached a predetermined value. Is this Value reached, the vacuum is activated that shipping item 2a sucked onto the conveyor 3 and activated of the conveyor 3 in the direction 13 from the stack 2.
  • the subsequent packages 2b are moved by a movement of the Tracking means 1 in the direction of arrow 23 and also deducted individually.
  • the foremost package 2a is thus deducted when the two buttons 5 and 6 the appropriate distance of the front package Show 2a to front strand 3b.
  • the first one Shipping item 2a is aligned vertically and the Pressure in stack 2 exceeds a predetermined value Not.
  • Stack 2 is also erected if it is different from that shown is inclined. For example, it can be inclined that an upper end of the stack 2 in the transport direction of the Transport means 1 is inclined forward. So here it is the upper button 5, which is pivoted first.
  • the funding body 3 is in accordance with Figure 5 in the direction of the arrow 21 moved and the stack 2 erected. A counter movement of the means of transport 1 supported in the direction of arrow 20 this raising up.
  • a repeated pressure equalization in the case of a particularly difficult stack 2 is straightforward possible.
  • buttons 5 and 6 are mechanical sensors with which the inclination of the stack and its distance from the deduction plane A is noticeable.
  • An embodiment is also conceivable in which buttons 5 and 6 by optical or electro-optical Sensors are replaced, which corresponding inclinations one Detect stacks and distances and corresponding signals can deliver.
