Definitions

  • the invention is in the area of general cargo conveyance and relates to a device according to the preamble of the independent claim.
  • the device is used to create a stream of flakes of flat objects, in particular of printed products such as Newspapers, magazines or brochures.
  • a device for pulling apart in a shingled stream Printed product pairs (shingled stack flow) are known from EP 0 075 121 B1.
  • the current conveyed at a first speed on a conveyor belt of roof tile-like with leading leading edges on a conveyor belt arranged product pairs is converted into a shingled stream of individual products, for example with a double speed compared to the first speed, second speed is promoted.
  • the batch stream accelerated to the second speed and under a deceleration device performed that moved with one at the first speed Band each retains an upper product from a pair of products while the lower Product of the couple is further promoted at the second speed.
  • the Upper product is released by the delay device as soon as a subsequent one Product pair reached the delay device.
  • the scale spacing of the scale flow generated is the ratio of the two Speeds and depending on the scale distance of the supplied product pairs. If the scale spacing in the flow of the supplied product pairs is uneven, so it is also that of the scale flow generated.
  • a device for equalizing a scale flow is known from EP 0 254 851 B1 known.
  • the products are in an ineffective range stopped by a stop, the conveyor path immediately before the stop has a kink.
  • Driving cams arranged on driving wheels steer the leading area of each paused in a given cycle Product from the effective range of the attack, press it against one in the belt conveyor aligned in the new conveying direction and guide it into a clamping gap between this belt conveyor and one attacking on the other side of the product Conveyor role, whereby the product is conveyed further.
  • the principle of operation requires both actively driven driving cams and conveyor rollers as well as a kink in the conveying direction, i.e. a relatively complicated one mechanical construction.
  • the present invention is based on the object of a device to create the type mentioned, with which it is possible in a very simple manner is to create a stream of individual flat objects from a scale Scale stream of pairs of objects or generally from a scale stream of object stacks (scaled stack flow) or also from a stack of Objects.
  • the device should be suitable for one first shingled stack stream or from a stack another shingled one To generate a stack flow in which all stacks have predetermined, equal heights, or include the same number of objects.
  • the device should adhere to the regularity make very little demands on the supplied flow of objects, that is, it should be able to accommodate larger gaps occurring in this feed stream, in such gaps individually conveyed objects and also large piles of objects to process easily.
  • the flat objects are lying loosely on a conveying surface with leading leading edges in a preferably straight line Funding direction funded.
  • a probe roller is used to create the shingled stream and inserted a barrier, both of which act on the upper side of the shingled stream.
  • the feeler roller is located downstream of the lock and feels the created one Scale flow.
  • the lock forms one together with the conveying surface Passage gap, the width (distance of the barrier from the conveyor surface) through the Tracer roller is controlled, in that tracer roller and lock preferably mechanically coupled to each other, for example rigidly connected.
  • the width the passage gap thus varies with the thickness profile of the scale flow created and let an object stopped behind the barrier pass if the feeler roller is raised by the leading edge of the leading object becomes.
  • leading object is a scale in one represents a continuous stream of flakes or together with other objects forms the beginning of a scale flow (for example after a gap in the feed Current), and it does not matter whether the scanned leading edge is the Edge of a single item or the edge of a stack of items (e.g. a pair of objects). It doesn't matter how wide many objects are stowed behind the lock.
  • the passage gap allows one Item or a stack of items passing through if the thickness of the item or stack is not greater than the thickness of the leading edge of the leading object or stack.
  • the conveyor surface has a conveyor belt with openings and cooperates with one upstream of the barrier Suction device, such that a through the conveyor belt through the passage gap promoting object is sucked onto the conveyor belt.
  • the suction device is regarding the conveying direction arranged and / or possibly controlled in such a way, that the suction effect on an object lying against the lock only then becomes relevant if the leading edge of the leading object is the sensing roller has reached and thereby the barrier for the passage of the adjacent to the barrier Object is raised.
  • the suction device also works preferably without active control means.
  • the device the essential parts of which is the sensing roller and the lock controlled by the feeler roller and those with a conveying surface cooperates, very simply for different scale distances in the generated stream and adjustable for different object formats and thicknesses.
  • the scale spacing in the scale flow to be created depends solely on Distance in the conveying direction between the feeler roller and the lock. By releasing of an item triggered by the previous item is this Scale spacing essentially independent of distances, distance inaccuracies and speed of the objects in the supplied stream as long as this leads at least one item to the lock before the previous one Object reached the touch roller.
  • the distance between scales may be due to Conveying force (friction between the conveying surface and the objects) and to the Adjust friction between objects.
  • the invention also provides for buffering or stacking of objects the lock possible. This is particularly advantageous if the feeder Scale flow has large distances or even gaps. If before one If there is a sufficient number of objects at the lock, the Gap has no effect on the scale flow generated. If the gap is bigger, there is also a gap in the created stream of shed, but from after Gap fed objects again without problems and without special measures a shingled stream is created.
  • Figure 1 shows a very schematic representation of a first exemplary embodiment of the device according to the invention.
  • the most important elements of the device are a sensing roller 1 and a lock 2, which are arranged on a holding frame 11.
  • the holding frame 11 is positioned relative to a conveying surface 3 (for example a conveyor belt) which can be driven in the conveying direction F in such a way that the sensing roller 1 and lock 2 are directed against the conveying surface 3 and that the sensing roller 1 is positioned downstream of the barrier 2.
  • Tracer roller 1 and lock 2 are rigidly but optionally adjustably connected to one another by the holding frame 11, the tracer roller 1 being freely rotatable.
  • the holding frame 11 is substantially perpendicular to the conveying surface 3 against it and away from this (double arrow W) limited movement in a device frame 5 stored.
  • the device frame 5 has, for example, a guide block 51 with, for example, two (one visible) through holes 54 on, guided by the bolt 52 attached to the holding frame 11 (parallel guide) and are held by nuts 55.
  • a guide block 51 with, for example, two (one visible) through holes 54 on, guided by the bolt 52 attached to the holding frame 11 (parallel guide) and are held by nuts 55.
  • the guide block 51 and the holding frame 11 are slightly biased coil springs 53 arranged around the bolt 52, which the holding frame 11 drive away from the device frame 5 against the conveying surface 3, in a lowest position specified by the nuts.
  • the lock 2 follows the deflection of the feeler roller 1, whereby the width of the passage gap between conveyor surface 3 and barrier 2 to the Thickness of the scale flow conveyed under the feeler roller 1 remains adjusted and by scanning each leading edge step by step to release one opens another object.
  • the shingled stream created downstream of the sensing roller 1 and lock 2 has a scale distance that corresponds to the distance D in the conveying direction F between the touch point T of the touch roller 1 and the blocking point S. corresponds to lock 2.
  • the conveyor surface 3 is designed, for example, as a conveyor belt 31, the conveyor belt 31 preferably equipped with openings 31.3 and thus permeable to air and the device additionally has a suction device 32 with the A vacuum is generated locally on the lower side of the conveyor belt 31, by the object lying on the conveyor belt 31 at the relevant point 4 is sucked onto the conveyor belt 31. This locally causes the friction between the object and the conveyor belt 31 and thus those on the object effective conveying force increased.
  • the suction device 32 or an associated one lying on the conveyor belt 31 The vacuum chamber is positioned in the conveying direction F in such a way that its effect is effective a point A.1 begins, which is upstream of roller 1 and lock 2 and around at least the format length L of the processed objects 4 (expansion of the objects in the conveying direction) from the touch point T and at most by the format length L from the blocking point S (L + D from the touch point T).
  • the suction effect ends at a point A.2 downstream of A.1, the distance in the conveying direction F between A.1 and A.2 is advantageously at least as large as the distance D.
  • Such a design of the suction effect has the effect that the pumping power is at a low level object present at the lock 2 only then due to the suction effect is significantly strengthened when the preceding object reaches the touch roller 1 and has operated. Because between trailing edges of the objects Cavity 33 is formed above the conveyor belt 31, the suction remains another supplied object correspondingly smaller.
  • the device according to the invention advantageously has the one in FIG the setting options indicated by the double arrows E.1, E.2, E.3 and E.4, through which they are set for processing various items 4 can be.
  • the optimal settings are to be determined experimentally.
  • suitable Settings are particularly dependent on the scale spacing and the number Objects per scale in the scale flow to be created, of format and Thickness of the objects to be processed and the compressibility of the objects in the direction of their thickness.
  • the distance of the touch point T of the feeler roller 1 from the conveying surface 3 is relative to Distance of the blocking point S of the barrier 2 from the conveying surface 3 can be set (double arrow E.1).
  • This difference (height offset H.2, see Figure 3) is about the Thickness of the scales (thickness of an object to be processed or, if applicable a group of objects) of the scale flow to be created.
  • the adjustability E.1 is realized, for example, in that the feeler roller 1 is mounted in a bearing arm 12, the bearing arm 12 at one end via a parallel to the conveying surface 3 and perpendicular to the conveying direction F axis 13 is pivotally connected to the holding frame 11 and the pivot position of the Bearing arm 12 and thus the position of the feeler roller 1 relative to the holding frame 11 or to the lock 2 by one with the other end of the bearing arm 12 pivotable connected adjusting screw 14 is adjustable.
  • the distance D between the touch point T corresponds and blocking point S the scale distance in the created scale flow.
  • This scale distance is therefore adjustable by setting (double arrow E.2) the distance in Direction of conveyance F between feeler roller 1 and lock 2, which is achieved, for example, by this is that the shaft of the sensing roller 1 in a slot-shaped opening 12.1 of Bearing arm 12 is slidable and fixable at a desired location.
  • the length of the bolts 52 between the holding frame 11 and the upper edge of the bores 54 or the position of the nuts 55 on the bolt 52 determines the minimum Distance between the tactile point T or blocking point S and the conveying surface, by Rotation of the nuts 55 is adjustable (double arrow E.3).
  • the Minimum distance (H.1, see FIG. 3) of the sensing roller 1 from the conveying surface 3 in this way set so that it is greater than zero and smaller than the thickness of the vo securedden Edges of the scales (item or stack of items) of one to be created Scale flow. This prevents the tracer roller 1 on the conveyor surface 3 rolls off when no objects are being conveyed.
  • feeler roller 1 and lock 2 can be moved in the conveying direction (double arrow E.4), such that the distance between the feeler roller 1 and the effective area of the suction device 32 can be adapted to the format length L.

Only the traction roller 1 and the lock 2, which are rigidly connected to each other, and the conveyor surface 3 cooperating with the device are shown in a very simplified manner by the device.
  • Figure 3 shows the idle state of the device, in which the distance between the touch point T and the conveying surface corresponds to the minimum distance H.1 and the distance of the blocking point S from the conveying surface to the minimum distance H.1 plus height offset H.2, such that a first object through the passage gap can be promoted.
  • Figure 4 shows the device immediately after the feeler roller 1 has felt the leading edge of another object.
  • the feeler roller 1 and thus the lock 2 are raised by the thickness of the leading edge of this object and a further object 4 can be conveyed through the passage gap.
