Definitions

  • the invention relates to a device of the type mentioned in the preamble of claim 1 and a method of the type mentioned in the preamble of claim 11.
  • the task for example, of accepting successively delivered sheets from a transport device and passing them on to a subordinate station is, for example, in the paper processing industry, in the printing industry or in the banking industry, where bank documents are issued by a printing station and transferred to a removal compartment.
  • the prior art knows numerous devices or methods in which the sheets leaving the transport device are gripped by a gripper arrangement on their front edge, then conveyed essentially in the transport direction to the subsequent station and released there by the gripper arrangement. This release generally takes place during the movement phase of the gripper arrangement, so that the leaves move after their release in accordance with their kinetic energy until, for example, they strike the stops of the downstream station and come to rest there.
  • a device is already known from CH-PS 407 178, in which sheets by rotating suction bodies withdrawn from a stack of sheets and transported to a transfer position in which they are gripped by a gripper arrangement designed as a gripper roller at their front edge and released after a rotation of the gripper roller by a certain angle and transferred to the downstream dispensing station. The sheets are released during the rotation of the gripper roller. The released sheets then fall uncontrolled onto a conveyor chain belonging to the downstream station.
  • the storage drum of a device known from DE-A-38 30 339 collects one or more sheets during its forward rotation between the lateral surface and the holding means interacting with the lateral surface and pushes these by reversing the direction of rotation of the storage drum with the aid of a switch arrangement into a transfer channel.
  • the holding means are formed by a moving belt that wraps around the storage drum on most of its circumference. This belt is only interrupted at one point on the circumference and leaves there a gap through which the sheets both enter the intermediate storage formed between the belt and the lateral surface and emerge from this intermediate storage again. The leaves are not held in the area of this gap.
  • the holding means are formed by a arranged on the circumferential surface of the storage drum, with this rotating clamping device, which is controlled so that it is automatically closed when the storage drum is driven in the forward direction of rotation and automatically opened in the reverse direction of rotation; in addition, the storage drum is surrounded on at least part of its circumference by stationary guide devices arranged at a distance from the lateral surface.
  • the clamping device is opened by driving the storage drum in the reverse direction of rotation and moved into a position in which it can accommodate the leading edges of the incoming sheets.
  • the clamping device is closed by driving the storage drum in the forward direction of rotation, the leading edges of the sheets being clamped and held securely for the subsequent drum rotation. The remaining part of the sheets is held in contact with the storage drum by the guiding devices surrounding the storage drum.
  • the drive for opening and closing the clamping device can be mechanically coupled to the drive of the storage drum in a simple manner, as will be explained with reference to an exemplary embodiment. In this way, the positioning of the storage drum and the opening and closing of the clamping device can be accomplished with a single drive motor, so that a very simple and inexpensive construction results.
  • the stationary guide devices do not have to completely surround the storage drum, as is the case with the belt according to DE 38 30 339 A1; Rather, gaps can be provided between individual guide devices, in which lifting or switching devices leading to further transfer channels are arranged, so that the decision as to whether a sheet bundle is to be output or is conveyed into a reject compartment can be determined solely by the angular position of the storage drum and separate, controllable switches are not required.
  • the device according to the invention has the advantage that the sheets are held by the gripper arrangement until they assume their end position in the downstream output station, so that phases of an uncontrolled movement are avoided.
  • the original leading edge on which the gripper arrangement engages becomes the trailing edge and accordingly the free edge of the sheet becomes the leading edge, which can already be gripped manually, for example, while the gripper arrangement is still holding the original leading edge. In this way, a state in which the sheet moves freely can be avoided.
  • the device according to the invention is also particularly suitable for collecting and bundling several sheets delivered one after the other and for transferring the entire bundle to the subsequent station. For this purpose, several sheets are drawn one after the other into the buffer and placed on top of one another in a bundle; the entire bundle is then pushed out as a whole into the guide channel to the dispensing station.
  • the sheets are each drawn into a buffer forming a closed loop path to such an extent that the front edge of the sheet that is drawn in is again in the region of the entrance opening of the buffer.
  • this measure allows collecting and bundling of sheets that have been delivered one after the other in a particularly favorable manner, since the leading edges of sheets that have already been drawn in are gripped together with the leading edge of a sheet that is still to be drawn in and can be pulled through the closed loop path, the sheets that have already been drawn in merely adding another Circulate while the new sheet is drawn in and placed with the other sheets.
  • the sheets are cut off from a printed sheet material strip transported by the transport device at predetermined separation points, then taken over by the transport device and transferred to an output station.
  • a method according to the invention is provided using the described device, in which the respective front edge of the sheet material strip is detected, the sheet material strip is then drawn into the buffer until the next separation point is in a cutting position, the sheet material strip on it the separation point is cut off and that cut sheet is then completely drawn into the buffer.
  • the strip of material is accordingly simultaneously positioned in the cutting position during the drawing-in movement, in which the respective front sheet section is cut off.
  • This measure according to the invention is particularly suitable for bundling a plurality of sheets and for transferring the sheets in a bundled form, as will be explained in more detail using an exemplary embodiment.
  • the gripping roller forms with the guide surfaces an intermediate storage device which extends over the entire circumference of the roller in the form of a closed loop. It is understood that the guide surfaces are interrupted in order to form the required inlet opening and one or more outlet openings leading to the branching guide channels.
  • the gripping roller is rotated into an angular position in which the clamping device is in the region of the entrance opening. A sheet passing through the input opening is gripped by the clamping device and drawn into the intermediate storage device by rotating the gripping roller.
  • the gripping roller By reversing the direction of rotation of the gripping roller, the sheet in the intermediate storage with the original trailing edge is moved ahead until it is lifted off the roller surface by a switch arrangement and the sheet is directed into a guide channel.
  • Separate drive means can be provided for the cyclical drive of the gripping roller on the one hand and the adjustment of the clamping device on the other hand.
  • the adjustment of the clamping device is mechanically coupled to the drive of the gripping roller, so that for the cyclical drive of the gripper roller and for adjusting the clamping device, a drive motor is sufficient.
  • the gripping roller is freely rotatable about the roller axis and that the means for driving the gripping roller comprise a driver element which is connected to a reversible drive motor and is rotatably mounted about the roller axis and which is mounted on the gripping roller with the clamping device connected actuator engages and this in the forward direction of rotation of the driver element in a first, the clamping position of the clamping device corresponding stop position and in reverse rotation in a second, the open position of the clamping device corresponding stop position.
  • the clamping device when the driver element starts up in the forward direction of rotation, the clamping device is first clamped and only then is the gripping roller carried along; when the direction of rotation of the driver element is reversed, the clamping device is first opened and then the gripping roller is taken along in the reverse direction of rotation.
  • the gripping roller is preceded by a transport device for supplying a coherent sheet of sheet material formed from sheet sections arranged one behind the other and a separating device for severing the sheet of material at designated separation points and that the separating device is synchronized with the work cycle of the gripping roller so that after the respective front edge of the sheet material strip has been gripped by the clamping device and after a sheet section has been partially drawn into the buffer, the respective front sheet section is separated.
  • the gripper roller executes several cycles in succession, in addition to feeding sheets that have already been drawn in, until the desired number of Sheets lying on top of each other on the surface of the roller.
  • the direction of rotation of the gripping roller is then reversed and the sheet bundle is pushed out into a guide channel via a switch arrangement.
  • FIG. 1 shows a part of a receipt printer which prints bank receipts and issues them to the customer or, in the event that the receipts are not removed, conveys them to a collecting subject.
  • the document sheets 1 are fed from a printing station (not shown) by means of a transport device 2 to a gripper arrangement 3, which grips the sheets 1 at their front edge, pulls them out of the transport area and transfers them to a downstream station.
  • the gripper arrangement 3 comprises a gripping roller 4 lying transversely to the transport direction of the sheets 1, which is mounted in the printer housing 6 so as to be freely rotatable about the roller axis 5.
  • a clamping device 7 is arranged on the outer lateral surface of the gripping roller 4 and is adjustable between an opening position shown in FIG. 1 and a clamping position shown in FIG.
  • the gripping roller 4 is surrounded on part of its circumference by guide surfaces 8, 9, 10 which are arranged at a distance from the outer surface of the gripping roller.
  • the space between these guide surfaces 8, 9, 10 and the roller surface forms an intermediate storage 11 into which the sheets 1 can be drawn.
  • the distance between the roller surface and the guide surfaces 8, 9, 10 is selected so that several sheets can be picked up to form a bundle.
  • the guide surfaces 8, 9, 10 do not completely surround the gripping roller 4; Rather, gaps are left between the different guide surfaces 8, 9, 10, one of which serves as an input opening 12 through which the sheets 1 can enter the intermediate storage 11, and the other gaps each form outlet openings 13, 14 through which the sheets 1 can be pushed out of the intermediate storage 11.
  • the outlet opening 13 leads to a guide channel 15 which opens into a collecting compartment 16 (so-called reject compartment).
  • the outlet opening 14 leads to a guide channel 17, which at the same time forms a removal compartment from which the sheets can be removed, as will be explained in detail later.
  • a respective switch arrangement 18 and 19 is assigned to the outlet openings 13 and 14, respectively, which, when the gripping roller 4 rotates in the backward direction, lift the leaves from the gripping roller 4 in accordance with the arrow 20 and directs them into the associated guide channels 15 and 17.
  • the clamping device 7 comprises a movable clamping element 22 which is arranged so as to be pivotable about a pivot axis 23 lying essentially on the periphery of the gripping roller 4 and parallel to the roller axis 5 such that it has a clamping position (see FIG. 2) on the lateral surface of the gripping roller 4 and can assume an open position raised from this lateral surface (see FIG. 1).
