Definitions

  • the invention is in the field of general cargo conveyance and relates to a method and a device according to the preambles of the corresponding independent Claims.
  • the method and the device serve to produce a large number of same or similar, flat objects (piece goods), which are in a serial Supply flow are fed to position lying for further promotion.
  • An application example in which serially fed flat objects on one Further funding is positioned horizontally is the gathering of printed Partial products to a stack of partial products, which stack after the Usually gathered by binding or stapling to a finished printed product (e.g. book or brochure) is processed.
  • a conveyor belt is used as a further conveying means with in Direction of conveyance spaced cams or transverse walls through which the Conveyor line is divided into equally large conveying compartments.
  • These funding compartments are continuously or clocked on a series of consecutively arranged Conveyed feed points, at each of these feed points in each conveyed conveying compartment a partial product is deposited and in each conveying compartment during the conveyance along the conveyor line in this way a stack of Sub-products are created.
  • Each of these stacks contains at the end of the stack conveyor line as many partial products as it has been conveyed past active feed points is.
  • flat objects are usually parallel to their main surfaces one behind the other or overlapping each other against a feed point promoted and on the further funding or on one with the help of this Further conveying means of further stacked flat conveyed past the feed point Objects pushed.
  • the feed direction is against the top Direction of conveyance directed and intersects the level in which the conveyed Objects (further conveying plane) advantageously lie at an acute angle.
  • the Feed direction relative to the further feed direction (projection of the feed direction essentially freely selectable, that is, the feed direction can, for example, be aligned transversely to the direction of further conveyance (cross-feed) or it can be rectified with the conveying direction (rectified Funding).
  • Continuous funding is particularly suitable a feed of the latter type in which the feed direction in the same The plane perpendicular to the conveying plane lies like the conveying direction and this approaches in the same direction and at an acute angle from above.
  • Known devices for collating printed products point for the Feeding the sub-products for example, investors. These investors will Part products to be fed are usually supplied by hand and in a stacking shaft deposited. They are separated from the stacking shaft and into a flow transformed by being essentially parallel to their main surfaces one behind the other or conveyed overlapping each other against the feed point and on the resulting stacks are pushed. The position of the products on the emerging Stacking is correlated with the position of the products in the stacking shaft, that is, for a given product position on the resulting stacks the products must be filled into the stacking chute in an appropriate position.
  • feed feeders for example by means of unwinding stations, in which unwinding stations a shingled stream of printed products from one the corresponding roll is unwound and fed to the feed point, or also by means of a continuously supplied stream of flakes.
  • Even for such equipped feeders there is a fixed connection between the alignment of the products in the supplied stream of shed and their orientation towards the stacks created by collating.
  • This correlation should be changeable devices are to be provided with which the incoming shingled stream is reorganized can be, that is, reclassification devices, for example to reverse the shingled stream or to wrap a product wrap. Such devices are complex and take up a lot of space.
  • the object of the invention is therefore a method and a device create with which flat objects are fed in a serial feed flow be positioned horizontally for further funding, whereby with the same orientation of the objects in the feed flow by simple measures two different orientations of the objects conveyed horizontally should be able to be created.
  • the method should be designed in such a way that a simple device that is easy for the two positioning orientations is adjustable, can be carried out.
  • the flat objects become hanging and with their main surfaces fed vertically or skewed (not parallel) to the feed direction, such that one of its major surfaces leads and the other trails is.
  • This means that the flat objects are single or in the feed flow possibly in small groups of grippers running in series in one upper edge area held.
  • Lower edge areas are marked by a corresponding one Flexibility of the objects and / or by means of a corresponding pivotability the gripper relative to the upper edge areas in the feed direction slidable such that the objects are positioned in positions by suitable means can be brought in which the lower edge region of each object is not perpendicular is arranged under the upper edge area held by the gripper, but runs in front of it or runs after it.
  • a positioning means that this lower Edge area depending on the desired positioning orientation compared to the accelerates or decelerates the upper edge area, causing the object to move into a relative to its vertical position, which it takes up when it is freely suspended, crooked situation comes. If the item is positioned crooked enough, it will released by the gripper and by gravity and possibly by the positioning means finally positioned.
  • the lower edge area becomes opposite the upper edge area before positioning accelerated, the leading area of the flat object after positioning above.
  • the bottom edge area but after a delay, the trailing surface is on top after positioning.
  • the further promotion can be carried out as in the case of known methods, as briefly described above were, clocked or continuous, whereby with timed further funding, in which the objects are essentially stationary at that time Funding conditions are positioned, the funding, for example, across to further funding or can be aligned with this and with continuous further funding is advantageously rectified.
  • the funding for example, across to further funding or can be aligned with this and with continuous further funding is advantageously rectified.
  • equal feed becomes an accelerated lower edge area in the further conveyance before positioning to the leading edge area, a correspondingly delayed edge area to the trailing edge area.
  • the device according to the invention has a feed means and a positioning means , both of which are coordinated with further funding.
  • the feeder is used for the controlled, serial feed of the flat objects in a hanging position and has a plurality of one behind the other in the feed direction controlled gripper, which advantageously are freely pivotable in the feed direction relative to this.
  • the grabs are for example at regular intervals on a rotating transport element attached and have regular distances from each other.
  • the grippers can also be displaceable more or less independently of one another and for example buffered in front of the feed point and targeted for feed from the buffer be retrieved.
  • the feed means has deactivating means through which the grippers a specified discharge point for the discharge of the objects deactivated become.
  • the deactivation means can be controlled such that only a predetermined one Part of the gripper is deactivated while the gripper is not deactivated Discharge point without releasing the object they are holding.
  • the positioning means serves to decelerate or accelerate lower ones Edge areas of the objects supplied by the feed means in front of the Positioning.
  • the positioning means is designed, for example, as a conveyor belt, which extends below the grippers of the feed means and with the feed direction forms an acute angle, the apex of which is in the area of the discharge point lies.
  • the speed with which the positioning means the lower Edge areas moved against the discharge point is adjustable to at least two values, one of these speeds for acceleration of the lower edge areas is greater than the feed speed of the feed means and the other is smaller than that for a corresponding delay Feed speed or zero can be. If applicable, the position of the positioning means adjustable relative to the feed means.
  • the feed means and the positioning means are so on top of each other and on the Continued funding matched that an object when it was gripped by the A conveyance is released in a position so oblique with respect to the vertical has that it is supported by the action of gravity and possibly leading by parts of the positioning means at the intended location of the conveying means (e.g. in a funding compartment) and with the intended orientation (leading or trailing main surface above) is positioned.
  • Figures 1 and 2 show very schematically the principle of operation of the method and the device according to the invention using an exemplary embodiment, in Figure 1 in operation with acceleration of the lower edge areas for a lying position with the leading main surface at the top, in Figure 2 in operation with deceleration of the lower Edge areas for horizontal positioning with the trailing main surface at the top.
  • the figures illustrate continuous further funding in funding compartments with equal funding.
  • the figures and explanations in the following sections must be adapted accordingly for timed further conveyance and / or for cross-conveyance.
  • Figures 1 and 2 show as dash-dotted lines the feed direction F.1, the essentially the conveying path of the upper edge areas of the supplied objects referred to, the conveying direction F.2 and the conveying direction F.3 of the positioning means, which essentially the conveyor path of the lower edge areas of the referred to objects conveyed.
  • All three mentioned funding directions are in a same plane (paper plane of the figures), which is perpendicular to the conveying plane (perpendicular to the paper plane of the figures), one below the other, with F.2 and F.3 run essentially parallel to one another or slightly converging and F.1 forms an acute angle ⁇ with F.3 or F.2.
  • the discharge point E lies in the area of the intersection of F.1 and F.3.
  • Figures 1 and 2 also show a plurality of flat objects 1 which fed and positioned.
  • the figures can also be understood as Mapping of the same object in successive steps T each Phases (1.1 to 1.4) of funding and positioning.
  • Items 1 have two substantially parallel main surfaces oriented transversely to the plane of the paper 10 and 11, of which one (10) leads the other in the feed (11) is trailing, as well as upper edge areas 12 and lower edge areas 13.

  • the speed of the lower edge areas is not a constant speed is. So that the positioning means accelerate these lower edge areas can, its speed should be greater than the initial and greatest speed the lower edge areas. This speed is essential depending on the angle ⁇ and the length L. As will be shown later these parameters are advantageously set up such that the speed v.3 of the positioning means is approximately the same as the speed v.2 of the Further funding.
  • Figure 2 shows the same arrangement as Figure 1, but for a delay of lower edge areas and a lying position with the top facing trailing main surface 11 is operated.
  • the reference numerals are the same and the description is easy to adapt accordingly.
  • the speed of the lower edge areas 13 is not a constant speed; it is at the first contact with the positioning means so to speak zero and then growing. So that the positioning means the can slow down the lower edge areas, the speed v.3 of the positioning means so be very small or the positioning means must stand still.
  • the decelerating point should Stop the effect of the positioning agent on the lower edge area (Position P ', approximately L upstream of E). If the positioning means continue against the discharge point E as far as position P 'it must be in this front Region of a guidance of the released objects on the further conveyance serve and should then advantageously have a speed that about is the same as the speed v.2 of the conveying means.
