Definitions

  • the invention relates to a device for delivering specimens from a paddle wheel to form a shingled specimen stream, with at least one endless chain guided around a drive shaft of the paddle wheel, the individual chain links of which are evenly spaced from one another.
  • EP 0 059 873 B1 a device for removing printed copies from the paddle wheels of a folder has become known.
  • This device has a plurality of paddle wheels arranged side by side on an axis.
  • an eccentric disk is accommodated with respect to the axis of the paddle wheels.
  • This disk carries a stop wheel, which can be driven via an internal toothing with a predetermined transmission ratio.
  • the stop wheels rotate at a lower circumferential speed in comparison to the paddle wheels, so that the specimens still immersed in the forward movement and immersed in the paddle wheel pocket are already braked before they have reached the bottom of the pocket.
  • the entire length of the paddle wheel pockets can therefore not be used to reduce the kinetic energy inherent in the specimens.
  • the second embodiment disclosed in EP 0 059 873 B1 shows grippers, which are received on the stop wheel in the region of the stops and which clamp the front edge of printed copies.
  • the grippers are controlled by roller levers rolling on a fixed control cam and are associated with disproportionately high mechanical expenditure.
  • EP 0 164 440 shows a rotary delivery for picking up newspapers at high speeds.
  • a plurality of arc-shaped cantilever fingers are arranged on a central cantilever arm, each forming individual pockets between them, into which the newspapers to be laid out are immersed.
  • spring-loaded clamps are arranged in the area of the pocket base of each pocket formed by two cantilever fingers. The clamps are pushed back by the newspaper spine dipping into the bag. Since the clamps are spring-loaded, the newspaper spine is clamped between it and an adjacent cantilever finger.
  • the porosity of the newspaper has a favorable influence on the ink receptivity, particularly in gravure printing. The often simply printed newspaper copies are then relatively insensitive to smearing.
  • the printing substrate is partly printed with two layers of ink on both sides, the outermost layer of which has not yet fully hardened even after passing through a dryer.
  • the outermost layer of which has not yet fully hardened even after passing through a dryer.
  • EP 0 307 889 B1 has disclosed a device for issuing printed copies from the paddle wheels of a folder.
  • This document is based on the preamble of claim 1.
  • At least one cam segment is arranged there so that a chain is guided around the drive shaft of the impeller.
  • Angle and clamping pieces are arranged on the chain at the same distance from each other, which can be brought into operative connection with the blades.
  • the specimens entering the paddlewheel pockets are first gripped and aligned by angles fastened to the chain; the clamping piece acting on the specimens from the top presses them onto the shovel blade on which they rest.
  • the specimens are therefore pressed out of the paddle wheel pockets onto them during their movement, so that, despite the Teflon coating on the inside of the impeller blade, smearing or scratching of the underside of the specimen is not completely excluded.
  • the object of the invention is to achieve a display of specimens which is gentle on the material and takes place with a precise scale spacing, using the kinematics of moving delivery components.
  • An advantage of the solution according to the invention is that jamming of the specimens in the pockets can be avoided; when pushed out of the individual paddle wheel bags, they are only subject to their own weight and not to any force pressing them against their base, which increases the friction. Furthermore, the specimens accommodated in the pockets only rest on the edges of the protrusions of the chain links with their fold backs - that is, their most stable area. Since the front edge of each specimen is supported by the projections of the corresponding chain link, damage to the specimen front edge, for example by kinking, is excluded.
  • the projections of the chain links are provided with a rounded contour; this can be, for example, a circular settlement, an involute.
  • the individual paddle wheels and at least one first planet wheel of the chain are accommodated on an axial sleeve that is adjustable relative to the drive shaft. A rotatability of the axial sleeve on the drive shaft enables the entry area of the specimens into the individual paddle wheel pockets to be adjusted relative to the entry zone B.
  • the position of the chain is also adapted at the same time. It is also possible to change the phase position between the paddle wheels and a first planetary wheel after loosening the adjusting means.
  • a second planet wheel of the chain is also adjustable relative to the surface of a conveyor belt.
  • an arrangement accommodating the second planetary wheel can be displaced in recesses in the bearing arms.
  • inner edges of the pockets in the paddle wheels each run parallel to one another; Inlet funnels are formed in the outer circumferential region of the blade wheels between the inner edge of an airfoil and the outer contour of the previous airfoil. These allow the specimens to be laid out to enter the pockets of the paddle wheels more easily.
  • the rotational speed of the conveyor belt on which the specimens are laid out exceeds the rotational speed of the projections of the chain links of the chain. This ensures that the front edge of the individual specimens is pressed against the projections of the chain links until the projections leave the exit zone A; the rounded contour of the protrusions of the chain links favors this release process. Since the specimens already overlap each other, a change in the overlap distance is also excluded. The guidance of the specimens on the conveyor belt is maintained as long as possible.
  • Another favorable property of the device according to the invention is that the individual chain links of the chain are connected to one another by releasable connecting elements, such as snap locks. This can shorten or lengthen the chain; A change in the angle of inclination of the chain is also possible.
  • Fig. 1 shows the representation of a paddle wheel with an underlying conveyor belt.
  • An entry zone A is located above the paddle wheel 2;
  • the exit zone A lies below the impeller 2, above a conveyor belt 5.
  • the impeller 2 is driven by a drive shaft 3, on which a first planet wheel 6 of a chain 1 is also arranged.
  • the chain 1 consists of chain links 20 which are connected to one another in an articulated manner and each have a projection, each of which has an edge contour 8 (see FIGS. 3 and 4).
  • the chain 1 also rotates around a second planet gear 23, which is mounted in a shaft 12, which in turn is held by a lever 10.
  • An axis 13 is fastened to the lever 10 and can be moved horizontally in an elongated recess 11 of a bearing arm 24. After loosening a locking washer 14, the axle 13 can be moved in the recess 11 like a link, depending on the length of the chain 1.
  • the recess 11 is located in the lower part of a bearing arm 24 which is penetrated by an axis 27. On this axis 27 there is also a further bearing arm, not shown in FIG. 1. By means of a Adjusting flange 28, the axis 27 is attached to a side wall 29 of the folder.
  • a pocket 30 is delimited by blades 2.1 and 2.2.
  • the inner contour 15 of the airfoil 2.1 and the outer contour 17 of the airfoil 2.2 define an inlet funnel which favors the entry of the specimens 4 into the individual pockets 30.
  • the profiling of the pockets 30 caused by the inner contour 15 and the outer contour 17 slows down the specimens 4 before they strike the pocket base 16. Due to the rotation of the paddle wheels 2 in the direction of the arrow, the front edge of each specimen 4 reaches a projection of the chain link 20 from above. The front edge of the specimen is therefore underpinned and supported; the downward movement of the chain 1 in connection with the further rotation of the paddle wheels 2 causes the specimen 4.1 to be pushed out of the pocket of the paddle wheel 2.
  • each copy 4 to be interpreted is only released after it has been released by a subsequent one Copy 4 is partially overlapped.
  • a change in the overlap distance is then generally no longer possible, so that a high overlap accuracy can be achieved.
  • FIG. 2 shows a top view of the device according to the invention.
  • the drive shaft 3 is mounted in a side wall 2 of the folder; the adjusting flange 28, which supports one end of the axis 27, is also received on this.
  • the bearing arms 24 are supported in bearings 26 on the axis 27 and are received at the opposite end in roller bearings on an axial sleeve 19 which is rotatably fastened on the drive shaft 3. to carry out the rotation of the axial sleeve 19, the screw connection on the disks 18 must be loosened; the paddle wheels 2 together with the first planetary gears 6 can then be rotated, for example in order to influence the entry angle of the specimens 4 into the pockets 30 in the entry zone B (see FIG. 1).
  • a first planet wheel 6 is connected to two paddle wheels 2, around which the chains 1 rotate.
  • the paddle wheels 2 and a first planet gear 6 each are penetrated by screws 7, after their loosening it is possible to influence the phase position between the first planet gear 6 and the position of the paddle wheels 2.
  • Figure 3 shows perspective views of interconnected chain links.
  • each chain link 20 is each provided with a recess 22, through which a plug axis 21 can be guided in order to connect individual chain links 20 to one another. If - as shown here - the recesses 22 are designed as snap locks, the chains 1 can be shortened or lengthened as desired. The angle of inclination of the projections of the chain links 20 can also be varied with respect to the specimens 4 accommodated in the pockets 30. An exact adjustment of a shortened or extended chain 1 is ensured by the displaceable arrangement (10, 12, 13), which receives the second planet gears 23.
  • the individual chain links 20 are simple and inexpensive to manufacture from plastic; the snap locks 21, 22 enable simple assembly and disassembly of the chain 1.
