Definitions

  • the present invention relates to an apparatus and a method for intermediate stacking of mail items, in particular in letter processing systems.
  • Intermediate stacker z. B used in letter sorting systems as a link between coarse sorting lines and fine sorting machines.
  • the intermediate stacker buffers the irregularly arriving mail items so that the fine sorting machine can be loaded evenly.
  • the individual mail items to be stacked are clamped between a conveyor belt and a rear belt in the vicinity of the stacking location at which the mail item stack already exists or is formed by the mail items to be stacked.
  • the stack is formed, are that broadcasts individually one after the other ⁇ with its front edge up to a stacking wall conveyed.
  • the pelwand Sta ⁇ Before ⁇ derband from the broadcast and the program moves on ⁇ due to their inertia along a Leitzauns further direction at a certain distance from the stacking wall.
  • the consignment is conveyed into the space between the stack of consignments and the stacking roller by a rotating stacking roller, which is driven, for example, by the rear belt, and is conveyed on to the stacking wall.
  • the lower edge of the mail items of the mail item stack stands on an underfloor belt transverse to its direction of movement, which can be moved along the stack wall.
  • a separating device is provided, which can successively pull the mailings off the stack from the stack of mailpieces for further processing.
  • the underfloor belt is moved in the direction of the separating device in such a way that the stack lies against the separating device in such a way that the consignment that is closest to the separating device can be removed.
  • the stacking roll In the stacking area, the stacking roll must be brought into such a position that the items to be stacked between the stacking roll and the stack can be correctly transported to the stacking wall.
  • the movement of the stacking trolley with the stacking roller in the direction of the separating device takes place by mechanical coupling of the stacking trolley to the underfloor belt.
  • the underfloor belt and thus the stacking trolley with the stacking roller are moved in the direction of the separating device.
  • a three-phase motor with an electromagnetic clutch is provided, which moves the stacking trolley with the stacking roller along the underfloor belt in the opposite direction to the pickup roller depending on the item to be stacked.
  • a lever is placed near the stacking roller and the stack of mail presses on it.
  • the lever actuates a proximity sensor, which emits a signal for switching the clutch and thus a movement of the stacking trolley to the rear, that is to say in the direction away from the take-off roller, as soon as a certain minimum pressure acts on the lever.
  • the coupling is released again and the stacking trolley remains in the position it has now assumed.
  • the object of the present invention is therefore to ensure that the intermediate stacker functions properly even in the case of mail items of uneven thickness or particularly heavy mail items. This object is achieved by an intermediate stacker with the features of claim 1.
  • the intermediate stacker has a stacking roller, a stacking trolley, an underfloor belt, a separating device, a pressure measuring device in the vicinity of the stacking roller for measuring the pressure of the stack against the pressure measuring device and a device for detecting the inclined positions of the stack of items.
  • the stacking roller is arranged on the stacking trolley.
  • the stacking trolley can be moved along the underfloor belt by a drive.
  • the separating device is arranged at one end of the underfloor belt.
  • the mail items to be stacked are successively conveyed between the stacking roll and the mail items already stacked by the stacking roll rotating about their axis up to a stacking wall and are then on the underfloor belt transverse to its direction of movement.
  • the separation device at the other end of the stack can pull off the consignment that is adjacent to it and thus reduce the stack of consignments again.
  • the stacking mail items increase the pressure of the stack on the pressure measuring device, which is arranged in the vicinity of the stacking roller.
  • Deducted mail items and thus a movement of the underfloor belt in the direction of the take-off roller reduce the pressure on the pressure measuring device.
  • the stacking trolley is moved until the optimum stacking pressure is reached for stacking.
  • the device for detecting inclined positions of the stack of mail monitors the stack of mail. If it reports an inclined position, an electronic control circuit controls the stacking trolley and / or the underfloor belt so that the inclined position is eliminated. Until the inclination, the information of the pressure measuring device is not taken into account.
  • the stack With an inclined position to the front, i. H. that the mail items are further away from the stacking roll with their top edge than with their bottom edge, the stack is preferably moved forwards by a brief movement of the underfloor belt, ie in the direction
  • the stack is preferably erected again by moving the underfloor belt and the stacking carriage to the front.
  • the stacking trolley travels forwards and backwards as a function of the pressure measuring device, provided that no inclination is reported.
  • the device for recognizing the inclined position from two levers lying one above the other, which are each printed against the stack of mail items and each actuating a switch, the switching points of the switches being on a perpendicular to the underfloor band level and an inclined position being recognized if the switches have unequal switch positions.
  • a third lever as part of the pressure measuring device in the same vertical position as the two levers of the particularly preferred device for detecting the inclined positions and to equip the third lever with a driver stop and the other two levers with one
  • the two levers can be used to recognize inclined positions, on the other hand, they can also determine the pressure at the same time: if one of the two levers is subjected to a greater load than the third lever, it transfers the pressure via its drivers to the driver stop of the third lever and thus deflects it so that the lever which is most heavily loaded is decisive for the deflection of the third lever.
  • an analog sensor to measure the deflection of the third lever, since the travel speed can then be particularly advantageously adapted as a function of the position of the third lever for optimal stacking.
  • FIG. 1 shows the top view of a known stacking trolley with a stacking roller and a particularly preferred feeler lever arrangement
  • Fig. 3 is a sketch illustrating a particularly preferred together ⁇ men Wegs the sensing lever assembly
  • Fig. 5 is a sketch to show the inclined stack position to the front.
  • the mail items SE are transported between the front belt V and the rear belt H and are clamped along the guide rollers FR 2 , FR3, FR 4 , the guide fence LZ1, LZ2 supporting the guide.
  • the front belt V is steered around the guide roller FR4, while the rear belt H is guided further in the direction of the stacking roller SR.
  • a shipment that was located between the front belt V and the rear belt H is further requested from the guide roller FR4 due to its inertia in the direction of the stacking roller SR, is detected by the stacking roller SR and between the stacking roller SR and the stack of items ST up to the stacking wall SW requested.
  • a stacking spiral SP advantageously detects the consignment SE as it passes and at the same time presses it away from the rear belt H in the direction of the mailing stack ST.
  • the more mail items are stacked the more the stacking trolley SW must be moved away from the take-off roller AR.
  • the stacking carriage SW must be moved towards the take-off roller AR so that the stacking pressure is as optimal as possible for the subsequent consignments SE to be stacked.
  • the underfloor belt ÜB is moved with the motor Mi so that the consignment SE closest to the take-off roll can be pulled off the take-off roll.
  • the control of the motor Mi is taken over by the electronic circuit ES.
  • the control of the stacking cart SW is described below:
  • a particularly preferred feeler lever arrangement FH has three levers FHi, FH ⁇ , FH3, which lie one above the other in the same vertical position and are each pressed by the springs Fi, F 2 , F3 against the stack of mail items ST.
  • the levers FHi and FH 2 on the one hand operate the switches Si and S2, on the other hand, depending on their position, they can press their driver MI1 or MI2 onto the driver stop MA of the lever FH3 and thus also deflect the lever FH3.
  • the lever FH3 has, at its end opposite the stack of mail items, the magnet MG, which is guided past a Hall sensor HS.
  • the lever FH3 is deflected onto one of the levers FHi, FH2, FH3 and the magnet MG is thus brought into a specific position with respect to the Hall sensor HS.
  • the signal of the Hall sensor is converted into corresponding voltages in the electronic circuit ES for the direct current motor drive M 2 , which drives the stacking carriage SW via a toothed element Z.
  • the stacking trolley is moved faster, slower or not at all.
  • the switching points of switches Si and S2 are on one level to the underfloor band level. If the upper switch S2 reports "on ' and the lower switch Si ' off, this means an inclined position to the rear (. See Fig. 4).
  • the stack In the case of an inclined position to the rear, the stack is preferably erected again to the front by a brief movement of the underfloor belt ÜB and the stacking carriage SW. In the case of an inclined position to the front, the stack ST is preferably erected to the front by moving the underfloor belt.
  • the signals from the Hall sensor HS have no effect on the drive of the motor M2 and thus the movement of the stacking trolley SW.
  • the invention is easily modified.
  • a pressure measuring device and a device for detecting the inclined position can be used.
  • B. can be realized by two in the vicinity of the stacking roll transversely to the direction of movement of the underfloor belt ÜB superimposed light barriers and an inclined position is then recognized when the light barriers report different states.
