Definitions

  • the invention relates to a gear arrangement for at least one gripper moving along a movement path on a sheet-processing machine.
  • a sheet removed from the sheet pile is transported to a feed table, taken over by a grabber bridge of a gear arrangement equipped with at least one gripper, and transferred to the feed drum, which accurately feeds the sheet to a printing gap between a printing cylinder and an impression cylinder of the printing press.
  • the trajectory of the gripper is generated by the gear assembly. For example, if it is a vibrating gripper, it is generally pivoted back and forth about a fixed pivot point. This has the consequence that the arc - is pulled down - with respect to the plane of the investment table. As a result, the trajectory can optionally intersect with a deck mark. Furthermore, the swing gripper can occur during the return against running bow. The result is sheet disturbances, marks on the bow and possibly increased wear on the components of the transmission assembly. Strong cardboard can only be processed with additional facilities, reducing the amount of sheets processed per unit of time.
  • the invention is therefore an object of the invention to provide a gear assembly of the aforementioned type which can realize a trajectory of the gripper, in which the periodic execution of gripping, transport and transfer functions of the gripper listed effectively and precisely, minimizes wear and a high sheet capacity / time unit is possible.
  • the object is achieved in that the trajectory of the gripper from a back and forth pivoting one in a pivot point stored swingarm results and the pivot point along a pivot path is moved back and forth.
  • a trajectory of the gripper is generated in which the way out with arch above the return path without a bow.
  • This sheet running disturbances can be avoided because the gripper passes on the way back to the feed table a trajectory, which lies below the path of the still traversing sheet. It is essential that the trajectory of the gripper on the way - - away from the investment table - in particular completely over the trajectory of the gripper on the way back - to the investment table - is.
  • pivoting movement takes place along a partial circular path circular section and / or the pivoting track is a partial circular path.
  • Pivoting movements along circular sections can be precisely guided and easily derived from a rotational movement of the drive or other rotational movements of components of the sheet processing machine.
  • the pivot track is generated by means of a pivoting movement of a control rod about a fixed first fixed point.
  • one end of the control rod is rotatably mounted in the fixed point and the opposite end of the control rod hingedly connected to the rocker in the pivot point.
  • the fixed first fixed point is fixed to the frame with respect to a frame of the sheet-processing machine.
  • the trajectory is an annular track.
  • the annular track is a self-contained track, which ring is not circular in shape, but rather has the shape of an oval. However, this oval is not symmetrical with respect to the web on the way out and the web on the way back. Rather, after taking over the sheet from the feed table, the gripper first passes through a slightly rising arcuate movement in such a way that it touches the circumference of the feed drum in its apex. After that, the gripper lowers a bit again and arrives at its reversal point. Here, the gripper passes through a tight arc and then goes on an optionally slightly concave, but possibly also convex Train back to the turning point near the investment table.
  • the trajectory preferably has a more or less pronounced "tip", that is, the return movement is relatively abrupt - without a larger arc is traversed - in the forward movement over.
  • tip a shape of said annular track.
  • other ring shapes are conceivable.
  • the gripper is located on a carrier which is rigidly arranged on the rocker.
  • the angular position of the gripper is coupled directly to the angular position of the rocker.
  • the gripper is located on a carrier which is pivotally mounted on the rocker.
  • the angular position of the gripper is not predetermined by the angular position of the rocker, so that the carrier is either itself (active) moved by a drive to change the angular position or so (passive) is stored, that is a movement of the carrier through the coupling results with the driven swingarm, which changes the angular position of the carrier.
  • the carrier is pivotally connected to one end of a coupling, the other end is mounted in a stationary fixed pivotally mounted in a second fixed point.
  • the coupling, the carrier and the rocker thereby form a four-joint coupling gear, which allows a stable and precise guidance of the gripper on the trajectory.
  • a drive can move either the rocker or the coupling.
  • the components of the four-joint coupling gear are arranged in a U-shape, wherein the carrier is the base and the coupling and the rocker form the two legs of the U-shape.
  • the four-bar linkage transmission is due to the swinging back and forth of the rocker and the simultaneous forward and backward movement of the pivot point (these movements run synchronized to each other) generates a corresponding trajectory of the gripper, wherein further by the coupling a pivoting of the carrier and so that the gripper is performed.
  • a guide rod which has at least one joint and with their one End is pivotally mounted at the pivot point and with its other end in a third fixed point.
  • a control rod is provided which pivots at one end about a fixed pivot point and the other end has a pivot point at which the rocker is mounted. With this pivot point, the above-mentioned guide rod is pivotally connected to one end, the other end is pivotally connected to the third fixed point fixed.
  • the guide rod itself has a joint and drives the control rod, wherein it kinks in the joint. In the swinging back and forth swinging the swingarm further performs a controlled tilting movement, so that the arranged on her gripper is changed in its angular position.
  • rocker and control rod lie in one plane.
  • rocker, control rod and coupling lie in one plane.
  • rocker, control rod and guide rod lie in one plane.
  • FIGS 1 to 3 each show a schematic representation of three embodiments of a gear assembly 1.
  • a plurality of grippers are moved, which detect a coming of a sheet pile sheets and transport to a plant drum positionally accurate.
  • These grippers are preferably located on a gripper bridge, which extends out of the paper plane of the drawing or hineinerstreckt into this, so as to be able to attack by means of the gripper over the entire format width of the sheet at the front edge of the sheet.
  • a gripper bridge which extends out of the paper plane of the drawing or hineinerstreckt into this, so as to be able to attack by means of the gripper over the entire format width of the sheet at the front edge of the sheet.
  • the mentioned gripper bridge can each lead in one of their end portions.
  • the gear arrangement 1 is assigned a feed table 2 and a feed drum 3.
  • sheets 4 - supplied by a sheet pile of an investor a sheet processing machine, in particular sheet-fed printing machine - by means of suitable means of transport, that is, they move in the direction of arrow 5.
  • the gear assembly 1 serves the leading edge of the respective sheet 4 by grasp of the gripper and to transport to the rotating axis 6 rotating drum 3 to transport.
  • the gear assembly 1 has the following construction: A control rod 7 is pivotally mounted with its one end 8 in a first fixed point 9.
  • the first fixed point 9 is assigned to the frame 10 of the sheet-fed press.
  • the end 8 opposite end 11 of the control rod 7 is pivotally connected via a pivot point 12 with a rocker 13.
  • At the pivot point 12 opposite end 14 of the rocker 13 of the already mentioned gripper 15 is arranged.
  • the gripper 15 is arranged on a carrier 16, which has also been referred to above as a gripper bar.
  • the gripper 15 If the gripper 15 is in the position shown in FIG. 1, ie in the deflection point 24, it opens so that a sheet 4 delivered along the plane of the support table 2 is gripped at its front edge by closing the gripper 15. As a result of the overall movement composed of the two mentioned pivoting movements, the front edge of the sheet is raised above the plane of the contact table 12 and brought along the arcuate path of movement 20 essentially tangentially to the contact drum 2. In this way, the sheet can be precisely aligned by the conditioning drum 3 taken. On existing front edge and side stops should not be discussed here. It can be seen that the open gripper 15 on its return movement (return trajectory 22) passes through a deeper zone than during its outward movement, so that collisions of the gripper on its return movement and transferred to the plant drum bow are avoided.
  • FIG. 2 shows a further exemplary embodiment of a gear arrangement 1.
  • the gear arrangement 1 of FIG Figure 2 has a control rod 7, the order a first fixed point 9 on the frame 10 of the sheet-fed printing machine is mounted pivotably at one end 8.
  • the other end 11 has a pivot point 12 at which one end 25 of a rocker 13 is pivotally mounted.
  • the end 25 opposite end 14 of the rocker 13 has a pivot point 26, on which a carrier 16 is pivotally mounted.
  • the carrier 16 is designed angular, that is, it has a first leg 27 and - at an angle - a second leg 28.
  • a gripper 15 In the end portion 29 of the second leg 28 is a gripper 15.
  • the pivot point 26 is close to the corner region 30 of the two legs 27 and 28.
  • At the end 31 of the first leg 27 is a pivot point 32 to which one end 33 of a coupling 34 is pivotally articulated.
  • the other end 35 of the coupling 34 is pivotally mounted via a second fixed point 36 on the frame 10 of the sheet-fed press.
  • FIG. 3 shows a further exemplary embodiment of a gear arrangement 1 in which a control rod 7 can be pivoted about a first fixed point 9 so as to be pivotable on the frame 10 of the printing machine in accordance with the double arrow 17.
  • One end 8 of the control rod 7 is associated with the first fixed point 9 and one end 11 of the control rod 7 has a pivot point 12 about which a rocker 13 is pivotally mounted on the control rod 7.
  • the rocker 13 is angular designed, that is, it has a first leg 37 and a second leg 38.
