Definitions

  • the invention relates to a device according to Preamble of claim 1.
  • EP 0 140 823 B1 describes a device for separating flat objects of different thickness, for example letters known in which one Pneumatic separator is provided, the one All-round perforated tape for taking the first one with you Object on a feed table by negative pressure as well as an opposite pneumatic counter holder to hold the second item due to negative pressure.
  • the counter-holder works with a vacuum that is less than that through the perforated tape acting on the first object Vacuum.
  • this separator is in yours Structure and very complicated in their function.
  • a device for separating flat objects which are arranged in a stack, one at a time first, a specified outside of the stack specified object by a transport device is displaceable in the plane of the object and a device for preventing entrainment at least a second one, lying against the first object Object is provided by friction, to create a separation of two taken away Allows objects of different thickness and the structure is very simple and little is prone to failure.
  • the device for preventing entrainment at least one perpendicular to the direction of transport is elastically movable friction member that with the first object facing away from the surface of the second Object can be brought into contact if the Thickness of the two objects a predetermined minimum thickness exceeds, the friction member accordingly be raised so that it effortlessly comes in contact with the surface of the second subject and brought by the Friction with this hold back the second item can. It is within certain limits irrelevant the thickness of the two objects.
  • the friction member is preferably in the contact area not supported with the second object (1) Separation belt. This is useful on a drive roller stored and by in the direction of transport of the first object acting guide elements for Contact area with the second object. Due to its rigidity, the separating strap has an elastic one Pressure on the surface facing it of the second object without itself in it Contact area to be supported additionally.
  • the ratio of its speed to that of the first item should be about 1:10.
  • the transportation of the first item becomes convenient by means of at least one rotating conveyor belt carried out.
  • the upper run of the conveyor belt 2 supporting role is a separator, that of a circumferential elastic separating belt 4, a drive roller 5 on which the separating belt 4 its end facing away from the drive roller 3 is, and there are guide elements 6 and 7.
  • the driving role 5 drives the belt 4 so that it opposite to the opposite upper one Run of the conveyor belt 2 moves.
  • the distance between the lower end of the separation belt 4 and the upper run of the conveyor belt 2 is set so that if the two lowest items 1 have the smallest possible thickness, the separating belt 4 nor the surface facing away from the drive roller 3 of the second lowest item 1 touched safely.
  • the Guide elements 6 and 7 guide the separating belt 4 in vertical direction so that it does not dodge sideways can.
  • a stop 8 determines the zero position in the separator.
  • a double arrow 9 indicates that the Separation belt 4 with the drive roller 5 in height and thus the distance of the separating belt 4 from the transport belt 2 can be adjusted.
  • a counter spring 10 in opposite Directions for setting the separation quality adjustable. These adjustments can be made manually or done automatically.
  • the bottom item 1 is through the conveyor belt 2 to the left in the belt 2 and the slit 4 formed slot moves, and at the same time becomes the second lowest item 1 from the bottom item 1 through the between friction with them, then at least the second lowest object 1 hits against the elastic separating strap 4 and lifts it there the separating belt 4 due to the guide element 6 and 7 can not sidestep.
  • the separation belt 4 but has sufficient stiffness to Exert pressure on the second lowest item; and it is made of a material with great adhesiveness, which ensures that the friction between the separation belt 4 and the second lowest item 1 is larger than that between the two bottom items 1.
  • the separating belt 4 holds the second lowest item 1 so that ensures is that only the bottom item 1 from the stack is pulled out.
  • the opposite movement of the Separating belt 4 facilitates the mutual Separation of the two lowest items.
  • the transport belt 2 has approximately ten times the speed of the separating belt 4.
