Definitions

  • the invention relates to a device for desquamation Stack of essentially standing against each other Printed products, with a first transport device, with which the stack is fed to a second transport device which peels off the printed products from the stack and in the subsequent shingled stream in an increasing direction further promotes.
  • Devices of this type are known and in particular are used in a feeder of a saddle book to form a lying stack.
  • the investor withdraws from the bottom of each stack opens this by means of opening drums and places this on a running collection chain.
  • the standing one Stack must match the flow rate of the shingled stream horizontally to the fume cupboard using conveyor belts be advanced. With such devices it is possible To feed the feeder automatically.
  • the pressure on the devices is critical in such devices Print products in the take-off area, i.e. where the shingled stream is formed. If the pressure is too high, there is Danger of too many, e.g. a partial stack or none Print products removed or the print products damaged become. Carelessly formed stacks can also be used Gaps lead to disruptions. Create gaps in the standing stack Pressure changes between the stack face and the peeling tapes, leading to disorders in the formation of flakes leads. So far, there have been high demands on the Quality of the stack.
  • the invention has for its object a device of the type mentioned to create the less demanding requirements to the quality of the stack and which is easier in manufacturing and monitoring.
  • the device is said to still work reliably.
  • the invention is in a generic device solved in that the drive of the first transport device is controlled by means of a probe that the created when pulling off the foremost printed product Gap scans.
  • the stack can therefore be fed exactly designed for the gaps that arise when pulling off become. Large gaps result in a large stroke and small gaps corresponding to a smaller stroke. So that is self-regulating feed of the stack possible. To lead Irregularities in the stack to larger or smaller Gaps - in the trigger area, this becomes automatic when feeding considered.
  • the quality requirements of the stack are thus in the device according to the invention much smaller than before. Because the feed is self-regulating can be trained is none or one much smaller surveillance work required. It has also been shown that in the device according to the invention strong compaction and block formation largely can be avoided.
  • the tactile means has a sensing element that in the trigger area of the Stack engages and that when pulling the foremost Traces the printed product gap.
  • a touch organ can be used as a mechanical button very easily and inexpensively getting produced.
  • the width of the gap will preferably by means of a pivoting movement of the sensing element felt.
  • this can be done be designed particularly easily if the button is one horizontal axis is pivotable, the pivoting range corresponds essentially to the width of the gap.
  • the button is spring-loaded, so that it is against the front of the front one not yet removed Print product is excited.
  • a particularly simple drive for the first transport device arises when this is a drive shaft has and on this a pivot lever is mounted, the is connected to the drive shaft by means of a freewheel and in the freewheeling direction corresponding to a pivoting movement the button is pivoted.
  • the movement of the button or the feeler can be very easily in a corresponding Feed movement or a stroke of the transport device being transformed.
  • the pivot lever is preferably eccentric stored roller pivoted to the zero position. At this A corresponding stroke is exerted in the pivotal movement.
  • the device 1 shown in FIG. 1 has a frame 2 on which a first transport device A and a second transport device B are arranged.
  • the first Transport device A has two endless transport chains 3 on a drive shaft 8 and a deflection shaft 6 are led.
  • On the links of this transport chain 3 are Tab 22 latched according to Figures 3 and 4.
  • This Riders 22 have spikes 24 on the top, which in the direction of transport, i.e. are directed to the right in FIG.
  • For attaching the riders 22 to the links in the transport chain 3 have these cylindrical openings 23, into which the bolts of the chains 3 engage.
  • the riders 22 can for example be made of a suitable plastic his.
  • With the transport chains 3, according to FIG 2 shows a stack 20 of printed products 21 for the second transport device B promoted.
  • the printed products 21 are like indicated in Figure 2 parallel and somewhat obliquely upwards directed, the Back 21a is below each.
  • the teeth 24 are at the top Run of the chains 3 upwards and in Figure 2 after directed to the front and thus give the printed products 21 a Stop, in such a way that each one against her back 21a the direction of transport cannot slide.
  • the printed products 21 are thus through the transport chains 3 in the conveyed with the arrow 10 indicated transport direction.
  • the transport chains 3 can also by other suitable Transport organs, for example replaced by toothed belts become.
  • the second transport device B has several peeling belts 4, which are guided over a sheet 29. Like the figure 2 shows, the effective run 4a runs essentially parallel to the printed products 21 and is driven that it moves upwards in the direction of arrow 33 in FIG emotional. As shown in FIG. 1, the peeling belts 4 work with other tapes 5 together with the peeling tapes 4 the peeled printed products 21 and diagonally upwards in the stream of shingles and, for example, to one Transport the feeder not shown here. With this Scale flow is a lying stack in a known manner formed, which is processed by the investor. Peeling tapes 4 and the other tapes 5 are known per se and will be therefore not explained further here.
  • the drive chains 3 are according to Figure 2 and 5 to 7 each guided around a sprocket 27, each firmly with the Drive axis 8 are connected. Between the two sprockets 27 is a one-way bearing 9 is arranged on the Lever 14 is mounted.
  • This lever 14 is according to FIG. 2 counterclockwise freewheeling and clockwise driving. 5 shows with arrow 34 the drive direction of the lever 14.
  • a probe 18 arranged by a comparative thin plate or tongue is formed.
  • the feeler 18 is firmly connected to the lever 14 and approximately according to Figure 2 aligned parallel to the printed products 21.
  • the touch organ 18 thus extends obliquely upwards and reaches from below in the front into the stack 20.
  • the drive shaft 8 is attached to the frame 2 with two roller bearings 25.
  • a fastening part 16 is attached to the a frame-fixed tension spring 15 attacks and the lever 14 in Tension counterclockwise.
  • the sensing element 18 according to FIG. 8 becomes the foremost not yet removed print product 21 'on the end face pressed.
  • the tension spring 15 can also be replaced by a magnet or a pneumatic cylinder his.
  • an arcuate surface 12 arranged, which cooperates with an eccentric roller 11.
  • the roller 11 is with a not shown here Drive between those in FIG. Dashed line positions shown horizontal moved back and forth.
  • the lever 14 can the axis 35 of the drive shaft 8 clockwise against the retroactive force of the tension spring 15 can be pivoted.
  • the lever 14 clockwise is driving it and thus rotates the drive shaft 8 via the freewheel 9 clockwise.
  • the sprockets 27 are made accordingly rotated and thus the transport chains 3 driven.
  • a stack 20 located on the transport chains 3 becomes thus in Figure 2 in the direction of arrow 10 to the right the second transport device B moves.
  • FIG. 8 shows a foremost printed product 21 ′′, which is produced by the peeling strips 4 is detected and in the direction of the arrow 31 is promoted diagonally upwards.
  • the printed product 21 '' is carried along by the friction on the peeling belts 4.
  • the feeler 18 the drive device 7 is by the tensile force of the spring 15 pressed against the front F of the printed product 21 '.
  • the lower end 14a of the lever 14 is in the Area of action of the roller 11 and the first movement of the Roll 11 in Figure 8 to the left, the lever 14 on his applied to the lower end 14a in the direction of arrow 36 and thereby the lever 14 is pivoted clockwise.
  • This pivoting movement turns the shaft 8 clockwise and the transport chains 3 are turned accordingly driven.
  • the movement of the transport chains 3 the stack 20 and thus the printed product 21 'in FIG. 8 accordingly moved to the right.
  • the feeler 18 becomes accordingly pivoted and goes into the dashed line in Figure 8 position shown above. In this position it is Probe 18 'on the sheet 29 and defines one Zero position.
  • the corresponding position of the lever 14 is indicated by dashed lines in FIG. In this Position is the lever 14 outside the effective range the roller 11.
  • the printed product 21 '' withdrawn upwards and thus from Pile 20 desquamated.
  • the printed product 21 ' now advances and, as before, the printed product 21 '' from the peeling tapes 4 detected and upwards in the direction of arrow 31 deducted.
  • the 36 in FIG designated pivot angle of the feeler 18 exactly the thickness 30 of the printed product 32 corresponds.
  • This angle is 36 large, the lever 14 is correspondingly through the roller 11th pivoted by a correspondingly large angle and accordingly
  • the stroke of the two transport chains 3 is large.
  • a small angle 16 accordingly has a small stroke of the transport chains.
  • the feed of the transport chains 3 is thus automatically to the size of the gaps 32 customized.
  • the thickness 30 of a printed product 21 is for example 3mm or less.
  • the feeler 18 is one in the example shown Plate or tongue and overall the device 7 is clean mechanically.
  • the probe 18 by other tactile means for example is replaced by a sensor or an encoder, which the gap 32 detected and a corresponding signal on delivers a drive motor.
  • the mechanical version has however, the advantage of being simple and robust Parts can be manufactured and are therefore very reliable and also is inexpensive.
