Definitions

  • the invention relates to a device for storing folded Sheet on a transport device, with a rotating one Removal drum, the sheets from a stack individually holds and a first rotating opening drum and one second rotating opening drum, which passes the grasped Open the sheet at the edges opposite the fold and drop on the transport device, with one on the first opening drum arranged clamping device, which the sheets for opening and for further transport a projecting margin, and by means which the reach behind the edges mentioned in the removal drum and the Feed the clamping device.
  • such a device is from CH-A-408 065 of the applicant.
  • the first opening drum here has a drum sector, the one larger radius than the remaining drum sector of the opening drum owns and in the range of rotation of the removal drum engages as well as with a shoulder on the bow reaches behind and has a protruding edge a clamping device.
  • the second opening drum then opens the sheet and on the transport device, for example a Collection chain is dropped. In practice, this has Device proven in itself.
  • the drum sector with the bigger one Radius requires a comparatively large one Scope of the removal drum, which is the performance of this device limited.
  • JP-A-0 42 69 594 A similar device is known from JP-A-0 42 69 594 become. With this are the removal drums and the both opening drums each with their own synchronous motor driven. With a control device, the speed of rotation of these drums can be adjusted. The grasping the bow with the first opening drum takes place here also with a drum sector of the first opening drum. This can have the disadvantage of interlocking drums be reduced.
  • the invention has for its object a device to create the aforementioned genus, which has a higher performance enables and which also works reliably and still is inexpensive to manufacture.
  • the task is with a generic Device solved in that the above Means at least one movable on the first opening drum have mounted guide arm for reaching behind the edges when turning the first opening drum from one retracted position to the extent of the first Opening drum protruding position is moved.
  • the guide arm is pivotably mounted on the first opening drum at a distance from the axis thereof.
  • the guide arm can then be sunk in a comparatively simple manner by pivoting in the first opening drum.
  • the guide arm is pivoted backwards in the retracted position and is pivoted forwards in order to grasp the sheet as seen in the circumferential direction.
  • the guide arm engages in the rotary region of the removal drum and grips the rear part of an arc, which is thereby deflected radially outward and is fed to the clamping device.
  • the guide arm can be lowered again with a swiveling movement in the opposite direction.
  • the sheets are then handed over to the first opening drum particularly reliable when between these two drums a rotating pulley is arranged to which the bow after capturing the margins.
  • Figure 1 shows one of two spaced apart End shields 46, on which a removal drum A, a first opening drum B and a second opening drum C are rotatably mounted.
  • the arrows 28, 29 and 30 indicate the direction of rotation of these three drums A to C.
  • the drive these drums are known per se and are therefore here not explained in more detail.
  • the device is for example Part of a saddle stitcher and is used from a stack 2 Place sheet 1 individually on a transport device 6. This transport device 6 is only hinted at here and for example a collection chain well known to the person skilled in the art saddle-shaped pads 6a and carriers 6b.
  • a Gripping device 49 detects the bottom sheet of stack 2, for example, sucked in and with a pivotable clamping lever 20 fixed on the fold 3 on the removal drum A.
  • the arc 1 lies on the removal drum A according to FIG. 1 and is moved with it in the direction of arrow 28.
  • Guide cylinder segments 50 and 51 prevent the captured sheet from the rotating removal drum A.
  • the first opening drum B rotates in the direction of the arrow 29 around the axis 11 and has a rotating clamping device 48, which essentially consists of a jaw 40 with a Clamping surface 41 ( Figure 6) and a pivotable lever 16.
  • a rotating clamping device 48 which essentially consists of a jaw 40 with a Clamping surface 41 ( Figure 6) and a pivotable lever 16.
  • the shaft 12 is on their Ends rotatably supported on disks 54, of which in figure 6 only one is shown. These disks 54 are non-rotatable connected to the axis 11. At least one end of the shaft 12 is a pinion 13 attached to the toothed segment 14 of a two-armed control lever 15 combs.
  • This control lever 15 sits on the disc 54 and is limited around an axis 37 swiveling. At a distance from axis 37 is on the control lever 15 a roller 38 arranged by means of a spring 36 a stationary cam 45 is pressed. At the Turning the first opening drum B becomes the two-armed Control lever 15 pivoted and by the engagement of the toothed segment 14 on the pinion 13 are the guide arms accordingly 7 pivoted.
  • the guide arms run in one position 7 according to FIG. 2 approximately radially to the axis 11 and with a free end 7a over the circumference 27 of the first Opening drum B and grasp between the two segments 50 and 51 into the removal drum A.
  • the pinion 13 is here according to Figure 2 at one end of the tooth segment 14.
  • the rotational movement of the first opening drum B is on the Rotary movement of the removal drum A matched. this is also valid for the above-mentioned pivoting movement of the arms 7.
  • This Swivel movement is set so that the arms 7 according to Figure 1 so engage in the removal drum A that they leading sheet 1 at the rear edges 4 and 5 reach behind and with a convex guide surface 10 (FIG 6) according to Figure 2 steer outwards and guided the clamping device 48 feed where the above margin 5 and so sheet 1 is made.
  • the clamping device 48 has two clamping jaws 40 on, each attached to a rotating disc 24 are and each have a clamping surface 41 which the gripper or clamping lever 16 each with a spring 42 can be pressed.
  • the clamping levers 16 are each on an axis 45 on one of the two Disks 24 stored and with a control curve, not shown here pivotable. In the pivot position shown in Figure 2 are the two levers 16 with their front free end 16a arranged at a distance from the respective clamping surface 41, such that the edges 4 and 5 by the guide arms 7 in the position shown in Figure 2 can be performed. At the The levers continue to turn the first opening drum B.
  • the swivel ranges of the two levers 16 and 17 correspond essentially to a recess 25 (FIG. 6) of the respective Washer 24, which can be seen tangentially in the Has recess 25 extending nose 26. So the edges 4 and 5 cannot fall behind the levers 16, 17 is one Nose 26 provided, according to Figure 6 over the two levers 16, 17 are arranged and protrude somewhat.
  • the lever 17 is with a curve not shown here against a spring 56 panned. As shown for example in FIG. 1, the Lever 17 pivotally mounted on the axis 11. After clamping of the edge 5, the lever 17 in the in the figures 4 and 5 swiveled position shown.
