Definitions

  • the present invention relates to a device for conveying flat products, in particular printed products, according to the preamble of claim 1.
  • Such a device is known from CH-PS 637 091 and the corresponding US-PS 4,333,559.
  • the conveying device has a deflection wheel arranged above the feed conveyor, around which a pulling element is guided, on which grippers are arranged one behind the other in the conveying direction.
  • Each gripper has an upper fixed jaw and a lower movable jaw. The grippers brought up to the scale formation from above each grip a pair of products lying one above the other in the area of their leading edges with their clamping jaws and conveys it away.
  • the conveying direction of the away conveyor is essentially parallel to the conveying direction of the feed conveyor in the takeover area.
  • the feed conveyor transports the products essentially in a horizontal direction, while the conveying direction of the conveyor runs from bottom to top.
  • the conveying device has individually controllable grippers which are arranged on a pulling element and, in a takeover area, grip the products fed by the feed conveyor at the leading edges and lift them upwards from the scale formation. The scale formation is thus peeled off.
  • the conveying speed of the conveying device is half as high as the feeding speed of the feed conveyor, two products lying one above the other come into engagement with a gripper, so that two superposed products are lifted off each other.
  • each individual product is gripped by a gripper and peeled off from the scale formation, or two products are pushed over each other, so that each gripper grabs two products lying one above the other and promoted away.
  • a device for conveying flat products which occur in a scale formation, in which each product rests on the preceding one in the manner of a roof tile is known from GB-PS 966,402.
  • a section of an endless rail spaced from the end of a feed conveyor for the scale formation, a section of an endless rail, in which a number of grippers are movably guided, runs in the vertical direction.
  • Each gripper has a fixed gripper jaw and a pivotably mounted gripper jaw, which is held in a closed position by means of a closing spring in which it rests on the fixed gripper jaw.
  • the grippers which are freely movable in the rail in the region of the vertical section, run together as a result of gravity to form a column, the gripper jaw of the one gripper, which is in the open position, being supported on the fixed gripper jaw of the preceding gripper and thus a gap between these grippers prevented.
  • the bottom gripper of the column is held back by a controllable bolt.
  • the mutual position of the feed conveyor, the rail and the bolt is selected such that a product delivered by the feed conveyor runs precisely with its leading edge between the open gripper jaws of the gripper held back by the bolt. This product, which enters the open gripper, interrupts a beam of light, causing the bolt to be withdrawn briefly.
  • the released gripper is strongly accelerated under the weight and weight of the gripper column.
  • the actuating arm runs from the backdrop, the movable gripper jaw swivels into the closed position and holds the product released by the feed conveyor between itself and the fixed gripper jaw firmly.
  • the grippers stand still during the introduction of the products between the open gripper jaws and each product that is fed rests on the preceding one in a scale-like manner.
  • DE-AS 11 76 675 discloses an apparatus for forming a formation, in which each printed product is arranged behind the leading one, from a supplied formation, in which two superimposed printed products are each arranged behind the leading pair of printed products.
  • the supplied pairs of printed products are spaced apart.
  • the lower of two printed products lying on top of each other is gripped by a suction roller and held by it during one revolution, while the upper printed product is conveyed straight on.
  • the printed product released by the suction roll after one revolution is then conveyed away behind the printed product passed on straight ahead.
  • This known device is not suitable for the processing of printed product pairs fed in scale formation, since each printed product covers or is covered by both products of the trailing pair. Furthermore, there is no space to convey the individual printed products away one after the other.
  • the leading edges of the products lying one above the other in pairs are lifted from one another and a single product is fed to each gripper of the conveyor. Since the conveying direction of the conveying device extends transversely to the conveying plane and from the underside of the products upwards, the products lying one above the other in pairs can be introduced into the grippers of the conveying device without being displaced in the conveying direction of the feed conveyor. The products thus captured are lifted upwards from the supplied scale formation or, in other words, peeled off from the scale formation.
  • the separating device has a separating member which bends down the region of the leading edge of the product lying below in each case about an axis running essentially parallel to the conveying plane and transversely to the conveying direction of the feed conveyor.
  • the separating member has a rotatably driven suction roller provided with openings distributed around the circumference, which is connected to a vacuum source or can be periodically connected. The bottom of the the product lying at the bottom comes to rest on the circumference of the suction roller and is pulled by it to the suction roller, so that the leading edge of this product separates from the leading edge of the product above.
  • the underlying product can be detached from the suction roller by interrupting the connection between the suction roller and the vacuum source or by, for example, a wiping element lifting this product off the suction roller.
  • the separating device has a bending element which bends the product located below in a wave shape downwards.
  • the leading edges of the superimposed products are separated from one another in the area in which the grippers grip these products, while the other regions can abut one another. This means that even products with very low rigidity can be removed and peeled off individually from the scale formation.
  • the safe feeding of one product at a time to a gripper of the conveying device is ensured in a simple manner by designing the device according to claim 9. If the towing connection between individual grippers is formed by an elastically shortenable and extendable spring element, the distance between adjacent grippers being set to a fixed dimension in the takeover area by means of an inhibiting element, phase differences between the takeover of the products in the takeover area and the delivery in a downstream thereof Transfer area can be compensated without changing the conveying speed of the feed conveyor.
  • the device specified in claims 1 to 13 can also be used for conveying scale formations in which one product rests on the next one, whereby all products are influenced by the separating device and fed to the grippers of the conveyor, or the mode of operation of the separating device is switched off , for example by breaking the connection between the suction roll or the recesses in the endless belt with the vacuum source. If at least one gripper jaw of one gripper bears against a gripper jaw of the adjacent gripper when the grippers are open in the take-over area, it can be ensured that all supplied products are gripped by a gripper and transported away, since there is no space between the gripper jaws in which products are mistakenly located could be introduced.
  • FIG. 1 shows a take-over area of a device with a feed conveyor 10 and a removal conveyor 20, in which printed products 12, 14 fed in a scale formation S from a feed conveyor 10 are individually gripped and transported away by grippers 18 of a removal conveyor 20 in the region of their leading edges 16.

  • the deflection roller 30 is operatively connected via a chain drive 32 shown in phantom to a shaft 34 which is driven by a chain drive 32 'shown in phantom by a drive motor, not shown.
  • the direction of rotation of the deflection roller 30 is indicated by the arrow B.
  • the belt conveyor 22 is followed by a rotatably mounted suction roller 36. Between the belt conveyor 22 and the suction roller 36 there is an extension of the conveying plane 28 Guide plate 35 provided.
