Definitions
- the invention relates to a device for transporting individual, from a Printers or the like coming sheets or form sets, using a shaft for guiding the sheets or sets and at least one depending the position of the cutting edge controlled drive by which the sheets are captured and are moved over the shaft to a storage area or the like.
- the synchronicity of the sheets or form sets is also important for the transport Drives compared to paper, due to the roughness of transport rollers as well can be disturbed, as by different, over the course of long operating times Wear, different diameters of the transport rollers. Also the necessary start-up and run-down times of the drives for transport rollers can Influence transport behind the printing unit. Finally, with different leaf lengths Make sure that the distance of one after the other on the leaves or sets accessing transport rollers is smaller than the smallest length of the to be processed Leaves, resulting in a high cost of driven shafts with attached Transport roles leads.
- the invention has for its object to solve the problems mentioned and defects to eliminate known designs.
- the device according to the invention is also intended in be able to cut the sheets and forms with the printed side after at the bottom, ie "face down" in the continuous page sequence.
- the object is achieved in that for access and the transport of the sheets on both sides parallel to the edges of the shaft, guided, swing arms moved by a controlled drive are used, the free ends of which can be seen with the clamping devices that grip the leaves at the edge are.
- swing arms arranged on both sides of the shaft Connect the drive shaft to each other so that only one controlled drive motor is used must become.
- the rockers are advantageously moved by a crank drive which reverses the direction of movement of the wings after each transport.
- 1 to 4 show an elevation of one of two on both sides of the sheet edges or forms arranged transport devices during different operating phases.
- Fig. 1 shows the transport device before taking over the cut sheet with open pinch rollers.
- Fig. 2 shows the transport device when closing the pinch rollers for takeover of the sheet.
- FIG 3 shows the transport device at the end of the transport movement for depositing of the sheet.
- Fig. 5 shows a schematic representation of the structure of the device according to the invention in frontal view.
- a shaft 3 which from a printer whose transport rollers 4a receives coming sheets 5 loosely.
- the shaft 3 ends with its outlet 7 in a shelf 8.
- the outer wall 1 of the shaft 3 forms together with a rear Cover 9 a further shaft 10 in which a clamping device for detection and is moved to transport the sheets 5.
- the shaft 3 corresponds in terms of its curvature is an arc with a radius equal to the length of the rocker 11 corresponds with the attached clamping device.
- the rocker 11 can by a suitable drive 13 via the bearing shaft 12 also serving as a drive shaft in a Pendulum movement can be pivoted.
- the rocker 11 carries a clamping device for gripping and transporting the sheets 5.
- This clamping device consists of the pinch rollers 14 and 15, which can be closed like scissors.
- the pinch rollers 14.15 grasp the side of the edge of the leaves 5. In one by the position of the rear
- the cutting edge of the blades 5 determines the specific position of the blades 5, the drive 13 the rocker 11 clockwise into the position shown in FIG. 2.
- Through this Movement is guided in a slot of the rocker 11 bearing shaft 16 and Pawl 23, when starting against a rigid bevel associated with the housing G. 17, pressed down against the force of the spring 22.
- With the bearing shaft 16 is also the pinch roller 15 pressed down against the sheet 5.
- the associated extension 18 moves down.
- the wall 1 forms with a cover 9 a shaft in which the pinch roller 14 is moved by the rocker 11.
- This cover 9 is in front of the outlet 7 of the Shaft 3 retracted so far in the manner of a runner 26 that during the pivoting movement the rocker 11 around the axis of the bearing shaft 12, the roller 14 in the area of this Blade 26 forcibly rolls off. This rolling movement causes the sheet 5 to advance is moved from the shaft 3 in the direction of the tray 8.
- the bearing shaft 12 can be designed as a continuous shaft, so that with a drive 13 arranged on both sides of the blade 5 rockers 11 of the device be moved synchronously.
- a variety of driven shafts attached drive rollers the distance of which is determined by the smallest blade length and whose rotary movements must be synchronized, one comes after the invention with a curvature of the only matched to the maximum length of the leaves 5 Shaft and an adapted length of the rocker 11.
- the device according to the invention Since the movement of the cut sheets 5 in the shaft 3 when inserted through the Rollers 4a and / or 4b is completely free, the device according to the invention has none Effects on the movement of the sheets in the printer. This also results in high printing speed and fast sheet sequence very good printing results.
- the Construction allows use with very different throughputs of Leaf as well as use with different leaf lengths and widths.
