Definitions

  • the present invention relates to a device for selectively transferring flexible, flat products, in particular printed products such as newspapers, magazines and the like, from a scale formation transported along a first conveying path to a second conveying path, according to the preamble of claim 1.
  • This has a transfer conveyor with two articulated conveyor arms, each with endless, revolving conveyor belts, which are guided around rollers with the same axis in the articulated connection of the conveyor arms.
  • the first conveyor arm is fixed in place at its end which is effective for conveying and is remote from the first conveyor arm, and the second conveyor arm is guided at its free end in a curved backdrop.
  • a piston-cylinder system which is pivotally mounted at another end engages in order to pivot the free end of the second conveyor arm, that is to say the conveying inlet of the transfer conveyor, into the conveying path of a first belt conveyor by lowering the shaft, and that in a scale formation Feed products brought in on the first belt conveyor to a second belt conveyor downstream of the transfer conveyor.
  • the transfer conveyor is bent knee-like and the feed entrance is withdrawn from the conveying area of the first belt conveyor. The products brought up on the first belt conveyor are then conveyed further by the latter.
  • Pressing means arranged above the conveyor arms have two articulated interconnected, belt conveyor-like, each having their own, endless, circumferential pressure belts, with pressure elements, the pressure belts forming a conveyor gap together with the corresponding conveyor belts of the conveyor arms being guided around coaxial rollers in the articulated connection of the pressure organs.
  • the shaft carrying the rollers is slidably mounted on a rod which extends approximately in the direction of the piston-cylinder system and protrudes at right angles from the shaft of the rollers, and is biased against the latter, and the rod is guided on a pivot bearing so as to be displaceable.
  • the bearing plates of the conveyor arms encompassing the corresponding shafts and plate-like bearing members of the pressing members are connected to one another via tabs.
  • This construction of the transfer conveyor has the consequence that the conveying gap changes depending on the pivoting position of the conveying arms both in its position with respect to the conveying arms and in the gap thickness. This can result in products being shifted in their mutual position during the pivoting of the conveyor arms, which would no longer allow timed further processing, or that very thin products are not properly held in the conveyor gap. Since the products are fed into stacking shafts, their mutual position is also irrelevant.
  • An equivalent but differently designed device is known from DE-A-2 820 957.
  • This points a first conveyor with two vertically staggered belt conveyors for transporting printed products arranged in scale formation along a first conveying path.
  • a transfer conveyor is provided between this and a second conveying path in order to detach printed products transported individually or in sections from the scale formation and to feed them to the second conveying path via the step formed by the belt conveyors.
  • the transfer conveyor which is arranged after the step in the conveying direction and transports the printed products out of the scale formation at an angle upwards, has a stationary guide part and a slide which is telescopically displaceable therein.
  • a tongue directed against the step is pivotally mounted. With the sled in its lower end position and the tongue pivoted upwards, the scale formation is conveyed under the transfer conveyor along the first conveying path. When the tongue is pivoted downwards, it engages under the printed product conveyed over the step and directs it to the conveying gap of the transfer conveyor.
  • the carriage is withdrawn upwards and then the tongue is pivoted upwards to separate this printed product from the next one.
  • the speed of the upward movement of the carriage is lower than the rotational speed of the conveyor belts.
  • This rotational speed is equal to the conveying speed of the first conveyor, in particular if section-by-product printer products are to be extracted from the scale formation.
  • the switch-like conveyor device 10 shown in FIGS. 1 and 2 has a first conveyor 12 designed as a belt conveyor, the upper run 14 of which runs along a first conveyor path 16.
  • the conveying direction of the first conveyor 12 is indicated by F.
  • a transfer conveyor 20 is provided between the first conveyor 12 and the second conveyor 18, which is also designed as a belt conveyor and has two conveyor arms 22 and 24 connected in series and pivotally connected to one another.
  • the stationary conveyor output 20 'of the transfer conveyor 20 is immediately upstream of the beginning 18' of the second conveyor 18 and the conveyor input 26 is by means of a drive arrangement 28 acting on the second conveyor arm 24 by pivoting the two conveyor arms 22 and 24 like a knee from the one shown in FIG Solid lines shown working position, in a retracted position 26 'indicated by dash-dotted lines and can be brought back again.
  • printed products 30, such as newspapers, magazines and the like become in a scale formation S (see FIGS. 3-7) transported along the first conveying path 16 in the conveying direction F.
  • the conveyor inlet 26 of the transfer conveyor 20 is moved into the adjacent working position 32 formed by the upper run 14 of the first conveyor 12, so that the edges 30 ′ leading in the conveying direction F are moved Via the stage 32 conveyed printed products 30 enter the conveying inlet 26 and are fed along the conveying path 34 of the transfer conveyor 20 to the conveying outlet 20 'and the second conveyor 18. It should be noted that the conveyor section 34 is essentially constant regardless of the position of the two conveyor arms 22 and 24.
  • the first conveyor arm 22 is mounted in a stationary manner in the region of its end 22 'which is effective for conveying.
  • a shaft 38 is mounted on a frame 40 of the first conveyor 12 against supporting plates 42 protruding upwards, only one of which is shown in FIG.
  • End shields 44 are pivotally arranged at one end, at the other end of which the end shields 44 'of the second conveyor arm 24 are pivotally supported.
  • the two end shields 44 are connected to one another in their free end region by means of a bearing shaft 46, on which the end shields 44 ′ are pivotably seated with their end regions on this side.
  • a deflecting roller 48 is seated freely rotatable between the bearing plates 44, 44 '.
  • the upper, conveyor-effective section 50 of a conveyor belt 50' common to both conveyor arms 22 and 24 is guided, which one is free at the free end of the bearing plates 44 ' rotatably mounted roller 54 and a driven roller 54 'seated on the shaft 38.
  • the conveyor-effective strand 50 is carried by support rollers 56, only indicated in FIG. 1, provided between these rollers 54, 54 'and the deflection roller 48 and also supported on the end shields 44, 44'.
  • a further support roller 56 ' is provided on each pair of end shields 44, 44' adjacent to the deflection roller 48, over which the rear run 50 '' of the conveyor belt 50 'is guided in order to hold it against the deflection roller 48.
  • the drive arrangement 28 has a drive lever 58 which is mounted on the frame 40 so that it can be pivoted in a fixed manner and which is at the other end pivotably connected to the right end plate 44 'of the second conveyor arm 24 in the central region thereof, as seen in the conveying direction F.
  • the piston rod 60 of a piston-cylinder unit 60 ′ which is also supported on the frame 40 at the other end, acts approximately centrally on the drive lever 58.
  • the transfer conveyor 20 is made narrower in the direction perpendicular to the conveying direction F than the first and second conveyors 12, 16.
  • a pressure belt 64 is provided, the lower, pressing-on strand 64 'of which rests on the conveyor-effective strand 50 and with this a conveyor gap 66 forms.
  • On the end shields 44 adjacent to the bearing shaft 46 are bent outwardly and protruding arms 68, the free ends of which are connected to each other by a further shaft 70, above the conveying section 50 and pressing section 64 '.
  • On this further shaft 70 two pairs of tabs 72 are pivotally mounted, the free ends of which are each pivotally connected to bearing plate-like bearing members 74.
  • rollers 82 are freely rotatably supported, around which the pressure belt 64 is guided. From these, the pressure belt 64 runs with its rear run 64 ′′ along the bearing members 74 to further rollers 84, which are provided in the articulated connection between the bearing members 74 and the pairs of tabs 72 and around them to form a freely rotatably mounted on the further shaft 70 Roller 84 '.
  • the spring arrangements 80 provided in the middle area of the end shields 44, 44 'and on both sides each have a compression spring 86, the lower end of which is supported on a support 88 projecting outwards from the bearing members 74 and the upper end is supported on a tension rod 90 which is supported by the compression spring 86 and the carrier 88 runs through and is fastened with its lower end to a further carrier 92 protruding outwards from the corresponding end shield 44, 44 '.
  • the tension rods 90 are fixedly arranged with respect to the bearing plates 44, 44 'assigned to them, as a result of which the position of the bearing members 74, viewed in the longitudinal direction of the bearing plates 44, 44', is fixed.
  • the conveyor-active upper run 14 of the first conveyor 12 which is designed as a belt conveyor, runs in the direction of conveyance F from a deflection roller 94 which is freely rotatably mounted on the frame 40 at the beginning 12 'in a known manner slightly ascending to a step roller 96 and from there in the opposite direction to a deflection roller 98 and deflected around it below the step roller 96 to a further deflection roller 94 'at the end 12''of the first conveyor 12.
  • a restraint device 100 which has an endless pressure belt 102 which interacts with the upper run 14.
  • a support arm 106 protrudes from the frame 40 in the vertical direction, at its upper end a weight arm 108 is mounted, at the free end of which plate-like bearing brackets 110 are mounted approximately centrally. Deflection rollers 112, around which the pressure belt 102 is guided, are supported at the two ends of the bearing brackets 110.
  • a drive motor 114 is also arranged on the frame, which is connected via a first chain drive 116, indicated by dash-dotted lines, for driving the conveyor belt of the first conveyor 12 with the deflection roller 94 'and for driving the conveyor belt 50' of the transfer conveyor 20 with the roller 54 '.
  • Another chain drive 118 connected to the drive motor 114 drives via a plurality of chain drives connected downstream thereof and also indicated by dash-dotted lines 118 'to the pressure belt 102.
  • the second conveyor 18 is driven by the drive motor 114 in a known manner via the chain 38 and the chain drive 116 via a chain drive 120, which is also only indicated by dash-dotted lines.
  • the deflecting roller 48 which is wrapped around by the conveyor belt 50 'and driven by it, is coupled to the roller 84' via a further chain drive 122, likewise indicated only by dash-dotted lines, in order to drive the pressure belt 64 synchronously with the conveyor belt 50 '. All conveyor, pressure and pressure belts of the conveyor 10 are driven in rotation at the same conveyor speed v.
  • the first conveyor 12 is preceded by a feed conveyor 124, which is also designed as a belt conveyor, in order to feed the printed products 30 arranged in scale formation S to the first conveyor 12. Furthermore, the first conveyor 12 is followed by a conveyor 126, which is also designed as a belt conveyor, in order to feed the printed products 30 transported by the first conveyor 12 and not supplied to the second conveyor 18 to a processing station (not shown).
  • a generally known counting device 128 is provided in the area of the feed conveyor 124 in order to count the printed products 30 fed to the first conveyor 12.
  • the second conveyor arm 24 has a tongue 130 protruding in the direction of the step 32 in order to engage under the leading edge 30 'of the printed product 30 to be gripped by the transfer conveyor 20 when the conveyor inlet 26 is brought into the working position.
  • the printed products 30 fed in scale formation S lying on the upper run 14 of the first conveyor 12, are fed to the conveyor 126 via the stage 32 along the first conveyor path 16 (see also FIG. 1).
  • the conveying inlet 26 of the transfer conveyor 20 is in a waiting position 26 ′′ in the vicinity of the stage 32.
  • This waiting position 26 ′′ is achieved in that the piston-cylinder unit 60 ′ moves the drive lever 58 into an intermediate position between the two in FIG. 1 shown end positions pivoted.
  • the conveyor inlet 26 is so far away from the stage 32 that the leading areas with the leading edge 30 ′, which protrude freely over the stage 32 due to the inherent rigidity of the printed products 30, do not reach the conveyor inlet 26, but under it through, along the first conveying path 16. It should be noted, however, that at stage 32 the leading area of each printed product 30 is lifted off from the leading printed product 30 for a certain time.
  • the conveying inlet 26 becomes the working position shown in FIG spent. This is done by completely retracting the piston rod 60.
  • the conveying speed v of the transfer conveyor 20 is exactly the same as the conveying speed v of the first conveyor 12, the scale formation S is maintained when it is fed to the second conveyor 18, as shown in FIG. 5, and the printed products following the step 32 on the upper run 14 30 are conveyed along unchanged conveying speed v along the first conveying path 16.
  • the transfer conveyor 20 now remains in this position for as long as printed products 30 are to be fed to the second conveying path 17 (see also FIG. 1).
  • the printed products 30 supplied are counted by means of the counter 128 (FIG. 1). Based on the knowledge of the conveying speed v, the conveying inlet 26 can now be pulled out of its working position after a precisely predefined number of printed products 30 in order to interrupt the supply to the second conveying path 17 after the precisely predefined number of printed products 30.
  • the feed input 26 is moved away at a speed v 1 from the stage 32 upwards, which is greater than the conveying speed v of the printed products 30 supplied.
  • the last printed product 30 detected by the conveying input 26 becomes the following one Printed product 30 pulled away, with the retaining device 100 preventing the latter printed product 30 from being carried along (see FIG. 6). Furthermore, this high speed v 1 of retracting the conveying input 26 prevents with certainty that the first printed product 30 to be fed back to the conveyor 126 can get into the conveying input 26.
  • the subsequently supplied printing products 30 are again fed along the first conveying path 16 to the removal conveyor 126 and the printing products 30 held in the conveying gap 66 of the transfer conveyor 20 are conveyed to the second conveyor 18 at unchanged speed v and unchanged distances.
  • the conveying inlet 26 can now remain in its retracted position 26 'or, if further printed products 30 are to be redirected to the second conveying path 17, can be brought back into the waiting position 26' 'shown in FIG.
  • the conveying speed v of the printed products 30 can always be constant regardless of the position of the transfer conveyor 20. It is not necessary to increase the conveying speed v of the transfer conveyor 20 and the second conveyor 18 in order to achieve a separation of successive printed products at the stage 32. Furthermore, the conveying path 34 between the conveying inlet 26 and the conveying outlet 20 'remains approximately the same regardless of the mutual position of the two conveying arms 22, 24, so that the scale formation of the printed products 30 is maintained even during the movement of the transfer conveyor 20.
  • the speed of the conveyor-effective strand 50 in the area between the conveyor input 26 and the deflection roller 48 when the conveyor input 26 is brought into the retracted position 26 ' is slightly enlarged, which additionally supports the separation of the successive printed products 30 at stage 32 while maintaining the scale formation S in the area of the transfer conveyor 20.
  • the conveying input 26 is only brought into its working position for the time required to grasp this printed product 30.
