Definitions

  • the invention relates to a device for the removal of printed products straddled at regular intervals on a saddle-shaped support of a conveying device on rotating carriers.
  • a device of this type is described, for example, in CH-A-358'100 and can be used, inter alia, in a saddle stitcher in which a plurality of feeders are arranged along a conveyor device, which straddle the print sheets assigned to them in a specific order on the saddle-shaped support stack on top of each other so that they can then be transported to the stapling station by the conveyor.
  • the conveying end of the conveying device is formed by a lifting or lifting device, which comprises a lifting bar, which, respectively. is arranged to be raised and lowered under the support of the conveyor.
  • This lifting device is coupled by an actuation system to the drive movement of the conveyor device, so that the lifting bar can be periodically raised with a vertical and a movement component oriented in the feed direction through a slot in the support above such that the printed sheets lying on the lifting bar are pushed in between roller pairs arranged one behind the other are, the axes of rotation of the rollers are parallel to the plane of movement of the lifting blade and perpendicular to its oblique movement component.
  • one roller of a pair of rollers is driven and the others are freely rotatably mounted and pressed resiliently against the former.
  • this object is achieved in that the conveying device is arranged approximately tangentially below the orbit of at least one clamping device, which rotates in the vicinity of the conveying device in the same direction and with at least approximately the conveying speed of the printed products, and detects the printed products on the fold, so that a stepless deflection of the printed products can occur .
  • the device according to the invention could, of course, be used to remove printed products from a plug-in machine without making a change in principle.
  • the orbit preferably has an axis of rotation about which the clamping device rotates.
  • a revolving traction element, on which the clamping device is controllably arranged could serve the same purpose.
  • a clamping device provided with at least one clamping pliers proves to be advantageous, which is formed by a carrier driven around the drive axis, a holding body rotatably mounted at a radial distance from the driving axis on the carrier about an axis of rotation parallel to the driving axis, to which the clamping pliers is attached, and a gear mechanism driving the holding body with respect to its axis of rotation by an amount equal to the rotational angle of the carrier in the opposite direction and driven by the rotational movement of the carrier, whereby a gentle removal of the printed products from the support of the conveying device can be achieved.
  • a transmission has proven to be an expedient embodiment, in which the holding body is connected to a toothed wheel, which is drive-connected via an intermediate toothed wheel which serves to reverse the angle, with a toothed ring which is arranged coaxially to the drive axis is so that a regular removal process can occur.
  • a wheel of an endlessly rotating drive belt preferably a toothed belt, which is fixed coaxially to the drive axis and is rotatably mounted on the carrier and is connected to the holding body, has also proven successful.
  • the clamping device on the conveying device is assigned a lifting device which lifts the printed products at the takeover point from the support and is formed, for example, by a recess so that the printed products can be gripped by the clamping pliers on the fold.
  • the invention provides a conveyor which is arranged in the trajectory of the deflected printed products and which ensures trouble-free further transport.
  • the clamping pliers can have two movable parts of the pliers, which are fastened to shafts of two intermeshing tooth segments and can be pressed against the force of a spring, or the closing pliers can be actuated, by a roller which engages on a tooth segment and is supported on the carrier for control purposes.
  • the holding body connected to the gearwheel of the transmission is suitable for this purpose, and the one with a for controlling the clamping pliers Tooth segment drive-connected control roller engaging in a control path on the carrier.
  • a deflecting element which displaces the clamping pliers from an approximately vertical plane of movement and follows an adjustable guide is preferably provided on one of the pliers parts made of a resilient material, for example a deflecting element running on a guide Role.
  • FIG. 1 and 2 show a device 1 for the removal of a conveyor device 3 on a saddle-shaped support 2 astride transported print products 4. These follow at regular intervals on drivers 5, which are attached to an endlessly rotating traction element, in the direction of arrow F.
  • the conveying device 3 could, among other things, be assigned to a saddle stitcher and the proposed device 1 for removing a stapling station.
  • the rotational speed of the clamping tongs 8 can be slightly higher than the conveying speed of the printed products 4 on the conveying device 3, so that due to the increasing decelerating parallel speed component of the clamping tongs 8 after passing through the lowest point on the orbit - where the printed products 4 from of the clamping pliers 8 on the fold 9 can be avoided - a compression of the printed products by the driver 5 can be avoided.
  • the clamping device 7 consists of three clamping pliers 8, which are connected by a holding body 10 to a three-armed or star-shaped carrier 11, which could also be designed as a disk.
  • the holding body 10 is rotatably supported at a radial distance from the drive axis 6 of the carrier 11 about an axis of rotation 12 parallel to the drive axis 6.
  • the clamping pliers 8 are each arranged on the holding body 10.
  • the clamping device 7 has a gear 13, whereby the holding body 10 with respect to its axis of rotation 12 an angle of rotation of the same amount opposite to the angle of rotation of the carrier 11 are driven such that the clamping tongs 8 do not change the orientation position of a printed product 4 detected on the conveyor 3 on the further conveyor path.
  • the clamping effect of the clamping pliers 8 is parallel to their axis of rotation 12, respectively. aligned at right angles to the conveying direction of the printed products 4.
  • the gear 13 in turn has a gearwheel 14 connected to the holding body 10, which meshes with an intermediate gearwheel 15 which is intended for reversing the angle and which is in turn drive-connected to a toothed ring 16 arranged coaxially with the drive axis 6.
  • a transmission 13 which is designed as a traction mechanism, instead of the ring gear 16, a fixed wheel and for the gear 14 connected to the holding body 10, a rotatably mounted wheel for an endlessly rotating drive belt, preferably toothed belt, which is provided by the rotary movement of the Carrier 11, the clamp 8 each holds in a stable position.
  • a lifting device 17 is arranged to lift the printed products 4 from the support 2 of the conveying device 3. This moves below the fold 9 of a printed product 4 with a vertical and horizontal movement component, so that the printed products 4 are lifted from the support 2 on the one hand and at the same time set in a parallel conveying movement occurring on the conveying device 3.
  • the organ lifting the printed products 4 is provided under the fold 9 with a recess 18, so that the strip-like elements 19 of the pliers parts 20, 21 act exclusively on the printed products 4.
  • the lifting device 17 accompanying the printed products 4 on the conveyor 3 serves for a gentle transfer of the printed products 4 from the conveyor 3 to the rotating clamping device 7.
  • a conveyor 22 connects to the conveyor section covered by the clamping device 7 by approximately 90 °. This consists of a rotating drum 24, which is partially surrounded by one or more deflection belts 23 and rotates about an approximately horizontal axis, which, together with one or more endlessly rotating conveyor belts 25, form a conveying gap 26 opening into the flight path of the printed products transported by the clamping device 7.
  • FIG. 3 and 4 illustrate the formation of a clamp 8 of the clamping device 7 in the transfer area of the conveyor 22.
  • the vertical dash-dotted line 27 marks the trajectory of the printed products 4 transported by the clamping device 7.
  • the carrier 11 has the one rotating about the axis of rotation 12 Holding body 10 drive-connected to the gear wheel 14.
  • the holding body 10 serves to support two mutually engaging toothed segments 29, 30 with which the pliers parts 20 via shafts 31, 32 , 21 are connected.
  • the toothed spring 29 connected to these toothed segments 29, 30 for opening the clamping pliers 8 is anchored to retaining pins 34 projecting radially from the shafts 31, 32.
  • the closing movement of the clamping pliers 8 is initiated by a roller 35 which engages on the toothed segment 30 and is supported on the bracket 28 in a tax-effective manner and which follows a control path.
  • the pliers parts 20, 21 are made of a resilient material, for example spring steel, so that on the one hand they can be pressed over in the closed position of the clamping pliers 8 to achieve a higher clamping pressure, and on the other hand the resilient material allows the clamping pliers 8 in the case of thicker printed products 4 by one Forceps part 20 attached deflection roller 36, which runs on an adjustable guide, to change the trajectory of the printed products 4 easily, so that they do not line up with the conveying gap 26, which cannot be changed in position.
