Definitions

  • the present invention relates to a device for separating flat products, which are subtracted from a stack of flat products, according to the preamble of Claim 1.
  • feed stations along the transport device arranged, each comprising a feed mechanism, by means of which a single withdrawing flat product from a stack and feeding it to the transport device, to put together a book block in this way or to insert a newspaper in a pocket of a pocket feeder or in a newspaper carried in the pocket insert.
  • feed mechanisms usually include one Separating device for separating the individual ones stacked in the feed station flat products. The individual flat products are from the bottom of the stack deducted.
  • a separating device of this type is e.g. B. is known from US 3,988,016.
  • This Font is a high speed feeder for inserting inserts into Newspapers described.
  • the supplements are arranged in a stack.
  • a vacuum gripper element captures the bottom insert of the stack and transports it to one Pair of pull rollers, by means of which the insert is inserted into an open newspaper.
  • On Single sheet requires a different suction power and a different suction movement than e.g. Legs 120-page insert.
  • the device detaches one an axis pivotable angled double lever, the first end with a Guide rod for a vertically movable suction nozzle connected and the second end carries a cam roller for scanning an assigned cam.
  • the Double lever is rotatably mounted about an axis and is depending on the course of the swept curve pivoted about this axis.
  • Separating thickness or grammage can change the position of the axis in an arc eccentrically mounted shaft can be changed.
  • the double lever around the eccentrically mounted shaft pivoted such that a displacement of the upper and lower turning points of the vertical movement of the suction nozzle is reached.
  • Document EP 0 212 865 A2 also describes a device for separating a flat product from a stack by means of suction cups, which particularly in Gathering machines or inserting machines can be used.
  • the Suction cups are pivoted and have a single lever Provide lever mechanism. Actuation of the lever mechanism is carried out by one of the Circumferential line of a cam following the curve guide roller.
  • the object of the present invention is to determine the position of the suction cups To improve the separation device.
  • An inventive device for pulling and separating Flat products from a product stack include a suction mechanism with a upper and a lower part and with a central lever, through which one along the Center lever slidable axis runs.
  • the center lever is rotatable about this axis includes first and second ends, and one located at the first end Joint and a second joint arranged at the second end, the upper part the suction mechanism with the first joint and the lower part with the second joint connected is.
  • the maximum position is due to the mobility of the axis running through the center lever adjustable depending on the product to be transported. This is necessary as some products adjust the suction cups to a higher or lower level Require position so that the suction vacuum is maintained, which by the present Invention can be easily achieved. Due to the geometric properties of the Construction and due to the fact that the individual joints with other joints are connected, the height of the suction cups can be adjusted without lowering the Suction cups is affected. It is therefore possible to adjust the To achieve the highest position of the suction cups by moving the axis that the Represents pivot point of the center lever. Another advantage of the present invention is that the machine set-up times can be adjusted without any tools be shortened and that the suction cups can be adjusted while the Device is in operation.
  • Fig. 1 shows a perspective view of a separating device according to the present invention.
  • a plurality of suction arms 12 are with a mounting shaft 10 connected.
  • a suction cup 14, the position of which is arranged on each of the suction arms 12 is individually adjustable independently of the other suction cups 14.
  • the Mounting shaft 10 is via an upper lever 16 with an upper articulated lever 18th connected.
  • the previously mentioned components form an upper part 22 of the Suction mechanism, which is connected to a center lever 26.
  • At one end of the A first joint 28 is arranged with the middle lever 26, with which the upper joint lever 18 connected is.
  • the separating device further comprises a lower part 24 of the Suction mechanism, which a preferably triangular lower lever 32 and one has lower articulated lever 34, which with lower lever 32 via a joint 36 connected is.
  • the lower part 24 of the separating device is with the central lever 26 via a second joint 30 arranged at the second end of the central lever 26 connected.
  • a biasing element 38 e.g. B. a compression spring or a pneumatic actuator, presses the lower part 24 of the separating device against an eccentric 40 which is contacted by an eccentric roller 42 (see FIG. 2).
  • the Center lever 26 extends an axis 44, which by turning a knob 46 on the Center lever 26 attached or detached from this.
  • the position of the axis 44 with respect to the first and second joints 28, 30 is by opening or closing Moving an adjustment joint 48 in the direction of the first joint 28 or the second joint 30 adjustable.
  • the adjustment joint 48 is at one end on the axis 44 and at its other end 50 pivotable about this end 50 at a fixed one Element of the separating device, e.g. B. attached to the frame.
  • FIG. 2 The mode of operation of the separating device is shown in more detail in FIG. 2.
  • An eccentric 40 which includes a protrusion 52, rotates into that indicated by arrow A. Direction. As long as the eccentric roller 42 is not contacted by the projection 52 the lower part 24 of the separating device is not deflected, so that the Suction cup 14 due to the special geometric construction of the individual joints in its low position. If the eccentric 40 continues to rotate, the projection 52 makes contact of the eccentric 40, the eccentric roller 42 and thus causes the movement of the lower part 24th the separating device in the direction indicated by arrow B until the lower part 24 is in the position indicated by the dotted line. Thereby the center lever 26 is pivoted and the suction cup 14 is thus moved into its highest position, since the upper part 22 of the separating device is connected to the center lever 26.
  • the maximum position 54 of the suction cup 14 is dependent on the position of the Center point of axis 44 defined pivot point.
  • the axis 44 can be between an upper position 56 and a lower position Position 58 to be moved.
  • Such an adjustment can be done by loosening one Fastening knob 60 and turning a first adjustment knob 62 take place, whereby a with eccentric 64 provided with spirally arranged notches is rotated, which the Adjustment joint 48 moves up or down. After the adjustment, the Fastening knob 60 tightened again.
  • the pivot point defined by the center of the axis 44 to adjust a center lever 26 by moving an adjustment box 80.
  • the Verstellkasten is arranged on a shaft 86 and includes fasteners such.
  • B. Screws 82 which the adjustment box in a precisely defined position with respect to Hold the middle lever 26.
  • the adjustment box includes a central bore 84 through which the Axis 44 runs.
  • the adjustment of the Pivot point of the central lever 26 also take place in that an angle lever with a first lever arm 89 and a second lever arm 87 by one at one end of the Lever arm 89 arranged bore extending shaft 90 is pivoted.
  • the Angle lever 88 is preferably pivoted about shaft 90 in that the first Arm 89 of lever 88 is urged in the direction of axis 44, causing axis 44 is moved upwards. Accordingly, the axis 44 moves down when the first one Arm 89 of the angle lever 88 is moved away from the axis 44.
  • the movement of the first Arms 89 of the angle lever 88 to the axis 44 and away from it by any suitable means are triggered.
  • a spring device is preferred provided which a rod 96 extending through the bore of the spring 94 and a includes second adjustment knob 92.
  • the position of the suction cups 14 with respect to the suction arm 12 is adjustable, so that the suction cups 14 with respect to the position of the suction arm 12, preferably the type of fold break and the processing flat product can be customized.
  • This adjustment is necessary because a thin product has a sharp fold break, while a thick product has a rather rounded, soft fold break.
  • the type of fold break determines the Position in which the suction cups must rest on the products. This position can be for each suction cup of the separating device must be different. It is therefore advantageous if means for changing the position of the suction cup with respect to the suction arm are provided so that the position of the center point 70 of the suction cup 14 between a Outer layer 66 and an inner layer 68 can be changed.
  • this adjustment can take place via an adjusting screw 72, when the suction cup 14 rotates between its outer layer 66 and its inner layer 68 is moved.
  • the position of each individual suction cup 14 can vary Type of fold breakage of a product 74 to be processed can be changed. It is about a thin product, the suction cup 14 can be moved closer to the fold break. If necessary, the suction cup 14 can move away from the fold break of the product 74 to prevent the suction cup from sliding around the fold and so on Vacuum is lost. This individual setting can make you irregular shaped products where the fold break is not straight as usual, can be processed easily.
