Definitions

  • the present invention relates to a device for collecting folded printed sheets, according to the preamble of claim 1.
  • Such a device is known for example from DE-OS 36 16 566 or the corresponding US Pat. No. 4,735,406.
  • This has a collecting drum with saddle-shaped supports arranged parallel to a common axis of rotation and driven around it. In the direction of the axis of rotation, two feeders are successively provided for depositing folded printed sheets on the supports and subsequently a stitching station for stitching the printed sheets lying one above the other.
  • the collected and stapled printed sheets are placed on a conveyor belt for stapling immediately after stapling.
  • the stapling station has a plurality of pairs of stapling heads which are arranged at a distance from the parallel supports on a bracket which is pivotably mounted on the axis of rotation of the drum.
  • the bracket is moved back and forth by means of a swivel drive, the stitching heads simultaneously placing one clamp each in the printed sheets placed on the supports during the synchronization with the supports.
  • a wire is fed to each of these known stitching heads, each of which wire by means of a cutting device arranged on the stitching head a wire section is cut off.
  • This wire section is bent by means of a slidably mounted stamp around a die to form a clamp, which is pressed out of the stamp by means of a likewise slidably mounted plunger and inserted into the printed sheets.
  • a disadvantage of this known device is that the stapling station must have a complex drive which has to exert large acceleration forces, in particular at high processing speeds.
  • the movement of the stitching heads must be precisely synchronized with the supports during each working cycle of the stitching station.
  • a wire is to be fed to each stitching head, which is complex for moving the stitching heads, both for feeding the wire and for the stitching heads themselves.
  • EP-A-0 205 144 or the corresponding US Pat. No. 4,750,661 describes a stapling station for stapling printed sheets carried by a rotating cylinder.
  • a cross-shaped holding device which is driven to rotate against a direction of rotation of the cylinder about a shaft parallel to the axis of the cylinder, three stitching heads are arranged side by side, which run past three drawer section dispensers common to all corresponding stitching heads.
  • the circular movement path of the stitching heads touches the surface of the cylinder and the rotary movement of the holding device is synchronized with the cylinder in such a way that the printed sheets to be stitched together always meet stitching heads.
  • the cylinder and the Drant section dispenser are located on the outside of the movement spell of the stitching heads.
  • a device for collecting folded printed sheets from CH-PS 645 074 and the corresponding US-PS 4,408,755 is also known.
  • This facility also points a drum with supports running parallel to a common axis of rotation.
  • the folded printed sheets are connected to each other and placed on top of each other to form zigzag bands.
  • staples are placed in the tapes supported one above the other by the supports.
  • the stitching heads which are arranged essentially one behind the other at a distance from the supports, run along a closed movement path at a substantially the same speed as the supports.
  • the closed movement path of the stitching heads leads past a wire section dispenser common to the stitching heads.
  • a single wire section dispenser thus supplies all of the stitching heads of a stitching head arrangement, which keeps the necessary facilities for the provision of wire sections extremely small and, moreover, enables the stitching heads to be constructed simply, since the stitching heads themselves no longer have to have a cutting device.
  • the takeover of the wire sections by the stapling heads on the side of the movement ban of the stapling heads facing away from the orbit of the supports allows the staples to be processed in a position different from the stapling position. This allows practically any shape of the movement path and the arrangement of the wire section dispenser even where the movement path runs along the orbit.
  • the distance between the stitching heads along the path of movement is so great that when the staples are set, the distance between the staples corresponds to the distance between the supports.
  • the mutual spacing of the stitching heads can thus be slightly different with respect to the spacing of the supports.
  • FIG. 1 shows a collecting drum 10, as described in EP-A-0 341 425 or the corresponding US patent No. 5,052,667.
  • This collecting drum 10 has saddle-shaped supports 14 arranged around a common axis of rotation 12, running in the direction of the axis of rotation 12 and driven in the direction of rotation U.
  • a carriage 16 which can be moved back and forth in the direction of the rotational axis 12 is provided with a controllable clamping arrangement 18 for the folded printed sheets 20 straddling the supports 14.
  • a stapling station 22 has a stapling head arrangement 24 with stapling heads 28 arranged one behind the other along a movement path 26 coaxially around the collecting drum 10.
  • a stapling head 28 is assigned to each support 14, which are thus arranged essentially at the same mutual distance A as the supports 14.
  • a wire section dispenser designated 30, is provided, along which the movement path 26 passes.
  • This wire section dispenser 30 has a cutting device 32, by means of which wire sections 38 are separated from a wire 36 drawn off from a supply roll 34. Downstream of the cutting device 32 is a magazine 40 fed by the cutting device 32 with wire sections 38.
  • the device shown in Fig. 1 operates as follows. Seen in the conveying direction of the carriage 16, the Stapling station 22 upstream feed stations for printed sheets in a known manner. These feed stations each place a folded printed sheet 20 astride each support 14 passing in the direction of rotation U at the feed station. Before in each case a support 14 runs into the lower region of its circular path of movement, the relevant clamping arrangement 18 is clamped in order to hold the parts of the printed sheets 20 reaching into the corresponding carriage 16. In the course of passing through the lower half of the path of movement of the supports 14, the carriages 16 make a working stroke in the longitudinal direction of the rotational axis 12 to the next feed station or to the stapling station 22.
  • the stitching heads 28 are also driven in the direction of rotation U in synchronism with the supports 14.
  • a stapling head 28 runs past the feed wheel 42, it takes over a wire section 38 from the feed wheel 42.
  • the wire section 38 now held by the stapling head 28 is formed into a clamp, as is the case here will be described in detail below.
  • the clip is moved from the side of the stitching heads 28 lying on the outside in the radial direction onto the inside of the supports 14 brought to the side.
  • the stapling heads 28 concerned are placed on the printing sheets 20 placed one on top of the other on the supports 14 lowered and the clamps inserted into the printed sheets.
  • the distance A of the stapling heads 28 corresponds to the spacing of the supports 14. After the staples have been placed, the stapling heads 28 are raised again, after which the collected and stapled printed sheets 20 are fed to a removal station in the course of the next rotation of the collecting drum 10 in the direction of the rotational axis 12 become.
  • the collecting drum 10 shown in FIGS. 2 and 3 corresponds to that of FIG. 1 and is therefore no longer described in detail.
  • the movement path 26 for the stitching heads 28 is kidney-shaped and runs in an area D along the orbit of the supports 14 of the collecting drum 10.
  • the collecting drum 10 is arranged outside the movement path 26 and the wire section dispenser 30, which is only indicated schematically, within it.
  • the collecting drum 10 rotates counterclockwise U and the stitching heads 28 are driven in the opposite direction U 'at the same speed as that of the pads 14.
  • the distance A of the stapling heads 28 corresponds to the spacing of the supports 14 when the staples are set, so that in area D for setting the staples a corresponding stapling head 28 runs with each support.
  • FIG. 3 essentially corresponds to that of FIG. 2.
  • the movement path 26 is circular and thus the area D is essentially shortened to a point D '.
  • the respective stapling head 28 comes into contact only very briefly with the staple in the printed sheets 20 deposited on the supports 14.
  • the stitching heads 28 are arranged along their movement path 26 at a distance A, which corresponds to the distance between the supports 14 of the collecting drum 10 when the clamps are set.
  • the embodiment of the device for collecting folded printed sheets 20 shown in FIG. 4 has a collecting conveyor 46 as described in EP-A-0 346 578 or in the corresponding US Pat. No. 5,104,108 or with a similar structure in the EP -B-0 095 603 or the corresponding US-A-4,489,930.
  • This has a pulling element 50 which is guided around two spaced apart, only indicated by its essentially horizontal axes of rotation 48, deflection wheels, on which supports 14 are arranged at certain intervals one behind the other, parallel to one another and at right angles to the direction of rotation U.

  • the clamp 104 is ejected from the stamp 130 with the push groove 162, the lateral arms 104' simultaneously being pressed onto the support 14 stored printed sheets 20 are pushed.
  • the plunger 80 When the plunger 80 is lowered, it slides on the wedge surface 154 'of the clip guide lug 154, as a result of which the clip holding member 146 attached to the pivot levers 144 is pivoted clockwise (see FIG. 9).
  • the clip guide lug 154 holds the lateral arms 104 'of the clip 104 in the grooves 136 until the clip 104 is inserted into the printed sheets 20 and the clip guide lug 154 is pivoted out of the area of the grooves 136.
  • the bending units 206 are pivoted upward, which has the consequence that the portions of the lateral arms 104 'projecting into the region of the bending units 206 are bent toward one another (FIG. 14).
  • the plunger 80 is still held in the lower end position by the plunger link 78.
  • the plunger 80 After the plunger 80 has run out from the plunger link 78, it moves back into the upper rest position under the force of the compression spring 166, as shown in FIG.
  • the bending machine 206 is also pivoted back into its original position.
  • the actuating shaft 100 is released by the clamping lever 94, which pivots of the stamp 130 back into the rest position.
  • FIGS. 16 and 17 the wire section dispensers 30 indicated in FIG. 5 and assigned to the two stitching head arrangements 24 are shown enlarged. Each of these wire section dispensers 30 is constructed in the same way as the wire section dispenser 30 shown in FIG. 1.
  • the cutting device 32 is driven by a rotating toothed belt 208.
  • a pair of conveyor rollers 210 conveys the wire 36 clamped between them step by step in the direction of the arrow H.
  • a cutting knife 212 which can be moved up and down in the direction of the arrow I separates a wire section 38 from the wire 36 by lowering after each conveying movement of the wire 36.
  • the magazine 40 Downstream of the cutting knife 212, the magazine 40 is arranged below the cutting device 32. It has an essentially slit-shaped stacking shaft 214 running approximately in the vertical direction, in which the wire sections 38 falling therein can be stacked one above the other with a longitudinal extension running essentially in the horizontal direction.
  • a pre-stacking device 216 with a tongue 218 which can be moved into the area of the stacking shaft 214 and can be withdrawn from it.
  • a number of wire sections 38 separated from the wire 36 by the cutting device 32 are stacked.
  • these stacked wire sections 38 then fall together into the stacking shaft 214. This prevents the wire sections from being erected and tilted 38 during the free fall and guarantees a clean stacking of the wire sections 38 in the stacking shaft 214.
  • the two conveyor wheels 42 arranged below the magazines 40 are non-rotatably seated on a common bearing shaft 224 which is rotatably mounted on a pair of support levers 222.
  • the two conveyor wheels 42 are driven to rotate in the direction of arrow V by a drive device 228 which acts on the bearing shaft 224 via a drive belt 226.
  • Each conveyor wheel 42 has two parallel disks 230 spaced apart from one another, between which the holding members 44 are arranged along the circumference at certain intervals.
  • the holding members are U-shaped and have at their free ends which are directed outward in the radial direction over the periphery of the disks 230, protruding flanks 232.
  • a permanent magnet arrangement is provided on the holding members 44 in order to hold the wire sections 38 released from the stacking shaft 214 by the driver flanks 232 as they pass the magazine 40.
  • the stitching heads 28 are spaced further apart than the holding members 44. Accordingly, the peripheral speed of the feed wheels 42 is lower than the rotational speed of the stitching heads 28, so that the next stitching head 28 meets the next holding member 44.
  • the stapling head 28 thus runs past the holding member 44 and pulls with the ones arranged on the punch arms 128 Driver lugs 138 from the holding member 44 the wire section 38 in question and holds it by means of the permanent magnet 140 on the punch 130.
  • the holding members 44 are arranged in a generally known manner to be displaceable and spring-loaded in the radial direction in order to be able to take up tolerances and to ensure secure takeover of the wire sections 38 from the stacking shaft 214 and transfer to the stitching heads 28.
  • the initial region of the driver link 92 is shown in FIG. 18 in the direction of rotation U.
  • the follower rollers 86 of the drivers 82 run onto the driver link 92, which has the consequence that the drivers 82, which are guided on the holding part 68 in a radial direction, are lowered onto the relevant supports 14 of the collecting drum 10.
  • the V-shaped driver profiles 84 encompass the supports 14. This has the consequence that the stitching heads 28 arranged on the support profile 62 and not shown in FIG. 18 are precisely aligned with respect to the associated support 14 or the printed sheets 20 placed thereon. Furthermore, the drive of the holding arrangement 52 takes place exclusively by being carried along by the catches 82 which are in engagement with the supports 14.
  • the catches 82 are lowered onto the supports 14 only in the upper region of the orbit of the collecting drum 10, so that the means of the Stapling station 22 stapled printed sheets 20 in the direction of the axis of rotation 12 through the now Pads 14 and driver profiles 84 spaced apart from one another can be conveyed away, or the printed sheets 20 to be stapled can be brought into the area of the stapling station 22.
  • a stitching head 28 is now traced in the course of one revolution of the holding arrangement 52, starting at the wire section dispenser 30.
  • the stitching heads 28 pass the wire section dispenser, they are in their outer rest position, seen in the radial direction, in which they are spaced from the supports 14.
  • the punches 130 are pivoted back into the rest position, so that the free ends of the punch arms 128 are directed towards the outside when viewed in the radial direction.
  • the stapling head 28 runs past the relevant holding member 44 of the feed wheel 42, the wire section 38 fed from the holding member 44 is detached from it by the driving lugs 138 and taken along (FIG. 19).
  • the stitching heads 28 reach the area of the die 98, as shown in FIG. 20. Seen in the direction of the arrow U, the distance between the link-shaped die 98 and the shaft 120 decreases, so that when the punch 130 is in the rest position, the wire section 38 in question is bent into a clamp 104 and pushed into the grooves 136 of the punch arms 128 (FIG. 20 ). When the swivel link 102 is reached, the sliding shoe 200 runs onto it, which has the consequence that the actuating shaft 100 is pressed inward in the direction of arrow F in the radial direction. This translational movement of the actuating shaft 100 is via the pinion 190 in a pivoting movement of the shaft 120 implemented.
  • the plunger 80 slides back into its outer rest position, as seen in the radial direction, under the action of the compression spring 166 and the distance from the supporting part 118 which increases in the end region of the plunger link 78.
  • the stitching heads 28 are now ready to take over a new wire from the wire section dispenser 30.
  • the collecting drum 10 continues to rotate, the stapled printed sheets 20 are now conveyed in the direction of the axis of rotation 12 away from the area of the stapling station 22 to a removal station (not shown).
  • the wire section preparation By separating the wire section preparation from the stitching heads 28, these can be constructed very simply. In addition, only one wire section dispenser 30 is required per stitching head arrangement 24, which reduces the expenditure to a minimum. In addition, the wire section dispenser 30 can be removed from the area in which the clips 104 are placed in the printed sheets 20. As a result, there is sufficient time for the preparation of the clips 104 in the area between the wire section dispenser 30 and the clip setting area. In the case of stapling heads with pivotable stamps 130, the staples 104 can be prepared in a position different from the staple setting position 130 ', which means that the various functions of the stapling heads 28 are spatially separated from one another; this in turn has the consequence that the stitching heads 28 are simple in construction with small dimensions.
  • the die can be provided for bending the wire section 38 into a clamp 104 on each stitching head 28 itself. This has an eccentric shape with respect to the shaft, so that in the course of the pivoting movement of the plunger 130 from its rest division into the stapling division 130 'the bracket 104 is formed.
  • Such a die could be formed on the clip holding member 146 clockwise in particular as a change.
  • the drivers are arranged on the stitching heads; so it is quite conceivable that the pressing lugs 170 serve as drivers.
  • a separate drive for the stapling station 22 is no longer necessary and synchronization problems between the rotation of the collecting drum 10 and the stapling head arrangements 24 have been eliminated.
  • the traction element or the holding arrangement 52 can be driven in a rotating manner by means of its own drive motor. It is also conceivable that the wire section dispenser has an exchangeable magazine, or that the wire sections are fed directly to the stitching heads by the cutting device.
  • the punches 130 can be in a wire takeover position that is different from the rest position for the wire takeover.
  • the wire takeover position does not correspond to the clamp setting position 130 '.
  • the wire sections 38 run essentially parallel to the pivot axis 122.
  • Stapling heads which are particularly suitable for devices according to the invention for collecting printed sheets are described in the simultaneous EP-A-0 399 322 and US-A-5,098,002.
  • a device in which a stitching head is permanently assigned to each support, also allows the stitching heads of a stitching head arrangement to be mutually offset in the longitudinal direction of the supports. For example, every second stitching head can be slightly offset with respect to the other stitching heads arranged in one plane; the two groups of stitching heads then advantageously each pass their own wire section dispenser. When the stapled sheets are stacked, not all of the staples come to lie on top of one another.
