Definitions

  • the invention relates to a method and a device for separating the sheets of a paper stack, in particular for subsequent addressing of envelopes, postcards or the like, the bottom sheet of the paper stack being drawn in and removed using suction air.
  • the device for carrying out the known method essentially consists of a magazine for the paper stack and a feeder arranged underneath, for which suction air can be applied, for gripping and removing individual sheets of the paper stack.
  • the feeder is a rotatable suction drum and the magazine is arranged tangentially to the suction drum casing, a stationary suction chamber being located directly below the suction drum casing having holes or slots, preferably in the region of the tangential arrangement of the magazine.
  • the magazine is arranged so that the tangential line can be moved forward and backward and tilted.
  • the front stop of the magazine can also be adjustable in height. A blowing air nozzle in front of the magazine ensures that air is blown into the space between the suction drum and the magazine.
  • the known method but in particular the known device, work independently of the format and at a very high speed without abrasion and without interruption during the filling of the magazine.
  • the object of the invention is to simplify the separation of sheets of a stack of paper.
  • the device according to the invention for separating sheets from a stack of sheets is arranged in the machine frame 1 in which the individual machine elements are mounted (not shown). It has the sheet stacking magazine 1, in which sheets 11 lie one on top of the other as a stack 11a. These sheets 11 are to be separated.
  • the magazine 1 is preferably - as shown - arranged inclined to the front and is delimited at the front by the front stop 3 and at the bottom by the two front adjustable stack holders 4, 5 and the two rear stack holders 6, 7.
  • the stack holder 7 is not shown in detail, but lies in FIG. 1 from the side behind the stack holder 6 in the image plane.
  • the stack 11 a is thus held by the front stop 3 and carried by the stack holders 4.5 and 6.7.
  • the front stop 3 is preferably formed from a plurality of rods or tongues 35, 36 arranged side by side, of which at least one tongue 36 can be adjusted up or down in the direction of arrow g (FIG. 4).
  • a conveyor belt system 13 which consists of the transport rollers 9, 10, 12, of which at least one is driven, and the above the conveyor belt 8 guided.
  • the vertical rollers 9, 10 and 12 are spatially arranged in a triangle in such a way that the conveyor belt - as shown - forms a run 14, which runs preferably parallel to the bottom sheet of the stack 11a and runs under the stack. It is preferably provided that the inclination of the run 14 is adjustable, for example by the height adjustability of a roller 10 and / or 12 (arrow direction a).
  • the front stop 3 is also preferably pivotable (arrow b) and up and down (arrow c) adjustable and also the stack holder 4.5 (arrow d, Fig. 3) and 6.7 (arrow e) can be pivoted up or down are arranged, the entire device can be more or less inclined or adjusted horizontally.
  • a pressure-transport counter-roller 34 can expediently cooperate with the transport roller 12, as shown in FIG. 1.
  • the conveyor belt 8 is porous, so that air can be sucked through. Holes 15 are preferably provided in rows of holes, as shown (FIG. 2).
  • a suction box 16 is arranged under the run 14 of the drinking band 8.
  • the suction box 16 consists of the bottom 17, the side walls 18, 19, the ceiling 20 and a front wall 21 and a rear wall 22.
  • the box is thus essentially closed. However, it has openings in the ceiling 20, preferably a plurality of longitudinal slots 23 arranged parallel to one another (FIG. 2).
  • the stack holders 4, 5 are arranged on the side walls 18, 19 so as to be pivotable about the axis 26 (FIG. 3). They consist of the swivel arm 27, which is at one end on the axis 26 and at the other end carries the support nose 28 on the upper edge, which supports the stack 11 a. The respective position of the holder is ensured by the screw 29, which passes through the arch slot 30 in the holder 4 or 5 and which is screwed into a bore in the side wall 18 or 19.
  • the surface 31 of the base 20 is concave in the transverse direction (FIG. 4), the suction belt 8 nestling against the surface 31 with its upper run 14.
  • the conveyor belt 8 runs in the direction of the arrow f.
  • a blow pipe 32 is arranged in the transport direction in front of the lower edge of the stack 11a, with which air can turn blown against the front edge of the stack.
  • At least one roller 10, 12, preferably at least the front roller 12, is spherical (FIG. 5), the radius r of the tread 33 corresponding approximately to the radius of the concave arc of the surface 31 of the suction box 16.
  • the suction box 16 is connected with its bores 24, 25 to a valve-controlled vacuum and blowing air system (not shown) with which a vacuum is applied intermittently and the vacuum can be released again.
  • the magazine 1 of the device according to the invention should, because of the special storage of the stack 11a and to ensure the suction of only one sheet 11, only lead so many sheets in the stack that due to the weight of the stack there is no sagging of the bore on the underside of the stack, i.e. the bottom of the stack should be as flat as possible.
  • magazine 1 is preferably preceded by a further magazine 37, which is connected to a conveyor belt system 38.
  • the magazine 37 is shaft-shaped and has a large capacity, so that it can accommodate a larger sheet stack 39.
  • the magazine 37 arranged spatially above the magazine 1 is shown in FIG.
  • the bottom of the magazine is at least partially formed by the likewise perforated conveyor belt 42, which is endlessly guided over the rollers 41, 43, 44 and 45 (FIG. 1).
  • the roller 45 is preferably drivable by the motor 46 via a belt 47.
  • the perforated conveyor belt 42 runs in the direction of arrow k.
  • a suction box 49 is arranged under the horizontal run 48 of the conveyor belt 42, the surface 50 of which is flat, but also has longitudinal slots which are made corresponding to the slots -23 of the suction box 16.
  • the suction box 49 preferably has a plurality of slot groups one behind the other.
  • the suction box has connection bores 51 for hose lines of a vacuum system (not shown).
  • the entire transport system 38 can preferably be adjusted forwards and backwards in the direction of the arrow 1.
  • the device according to the invention operates as follows:
  • the conveyor belt 8 runs endlessly in the direction of the arrow f. Intermittent vacuum is applied to the suction box 16.
  • the vacuum can act on the bottom sheet and the drawn sheet adheres due to the vacuum on the conveyor belt 8 and is transported by this until the sheet is gripped by the roller 34 and transported on.
  • the vacuum is switched off and preferably released by blowing blown air into the suction box.
  • the sheet should cover the slots 23 as far as possible so that no further sheet is sucked in by the same vacuum phase.
  • the suction or vacuum phase is relatively short and, as described, only lasts until the sheet is gripped by the roller 34 and is transported on using other transport means, not shown. Then the vacuum is removed by blowing air into the suction box. There should be no excess pressure.
  • the next vacuum cycle which is valve-controlled in a known manner as well as the blowing phase, the next sheet is detected and transported away, the distance to the preceding sheet being determined and selectable by the vacuum frequency.
  • the magazine system 37, 38 is coupled to the separating system.
  • the transport system 38 is set in motion, a permanent negative pressure being applied to the suction box 49.
  • the sheets are generally drawn in a scaly shape from the magazine 37 onto the perforated conveyor belt 42 and transported from the conveyor belt into the magazine 1.
  • the sheets lie as a shingled stream on the suction box, so that the vacuum does not have to be switched off when the conveyor belt is stationary and the magazine 1 is not being refilled.
  • the stream of shingles covers the slots in the suction box so that the vacuum is maintained.
  • the sheets are expediently guided into the magazine by one or more guide plates 52, which are arranged between magazine 1 and roller 44, with, inter alia, the angle of attack of the guide plates contributes to the perfect stacking of the sheets in magazine 1. Since the speed of the transport system 38 is preferably greater than that of the transport system 13, the magazine 1 can be refilled with any desired amount.
  • the invention thus creates, with very simple means, a very fast-working device which implements a method which ensures a safe separation of the Guaranteed sheet of a stack. It is even possible to separate over 70,000 sheets per hour.
