Description

  • 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.
  • A device of this type is disclosed in U.S. Patent 2,815,949. 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. On the shaft on which the rollers are mounted, a piston-cylinder system pivotally mounted at another end engages in order to lower the shaft of the free end of the second conveyor arm, i.e. the conveying entrance of the transfer conveyor to be pivoted into the conveying path of a first belt conveyor and to feed the products brought up in scale formation on the first belt conveyor to a second belt conveyor downstream of the transfer conveyor. When the shaft is raised by means of the piston-cylinder system, the transfer conveyor is bent knee-like and the feed entrance is withdrawn from the conveying area of the first belt conveyor.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 this. Pressing means arranged above the conveyor arms have two articulated interconnected, belt conveyor-like, each having their own, endless, circumferential pressure belts, and the pressure belts forming a conveyor gap together with the corresponding conveyor belts of the conveyor arms are guided around coaxial rollers in the articulated connection of the pressure organs. The shaft carrying the rollers is displaceably 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 displaceably guided on a pivot bearing. 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 lead to products being shifted in their mutual position during the pivoting of the conveyor arms, which would no longer allow timed further processing, or very thin products to be incorrectly 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 has a first conveyor with two vertically offset belt conveyors for transporting printed products arranged in scale formation along a first conveyor 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 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 can be telescopically displaced therein. Two conveyor belts, the conveying, adjoining and thus forming a conveyor gap run from the rollers arranged at the lower end of the slide to rollers mounted at the upper end of the guide part, are with their return strands around further rollers provided at the lower end of the guide part and at the upper end of the slide led to compensate for the changes in the length of the conveyor dreams when moving the carriage. At the lower end of the slide, a tongue directed against the step is pivotally mounted. When the carriage is in its lower end position and the tongue is 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 via the step and directs it to the conveying gap of the transfer conveyor. As soon as the last printed product to be fed to the second conveying path has been gripped by the conveying gap, the carriage is pulled back upwards and then the tongue is pivoted upwards in order to separate this printed product from the following 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 sections of the printer are to be removed from the scale formation. As a result, the two printed products to be separated from one another are conveyed at approximately the same speed be changed, and the following printed product, which is under attack by the leading printed product held by the conveyor belts, can be lifted upwards and carried along due to the friction or can be shifted from its position relative to the other printed products of the scale formation.
  • It is therefore an object of the present invention to develop a generic device in such a way that the mutual position of the products to be fed to the second conveying path is retained regardless of the position of the transfer conveyor.
  • This object is achieved by a generic device which has the features of the characterizing part of claim 1.
  • Preferred embodiments of the present invention are specified in the dependent claims.
  • The present invention will now be described with reference to an embodiment shown in the drawing. It shows purely schematically:
    • Figures 1 and 2 in view and plan view of a switch-like conveyor; and
    • Fig. 3 to 7 a part of this device in different working phases.
  • 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. Above the first conveyor 12 there is a second conveyor 18, which is also designed as a belt conveyor and defines a second conveying path 17, the beginning 18 'of which, seen in the conveying direction F, lies between the beginning 12' and the end 12 "of the first conveyor 12 and the end of which is not shown 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 fixed conveyor output 20 'of the transfer conveyor 20 is the beginning 18'. of the second conveyor 18 directly upstream and the conveyor input 26 is by means of a drive arrangement 28 acting on the second conveyor arm 24 by knee-like pivoting of the two conveyor arms 22 and 24 from the working position shown in solid lines in FIG. 1 into a retracted position 26 'and indicated by dash-dotted lines again z When the conveyor input 26 is in the retracted position 26 ', printed products 30, such as newspapers, magazines and the like, are transported in scale formation S (see FIGS. 3-7) along the first conveyor path 16 in the direction of conveyance F. In order to redirect printed products 30 from the first conveyor path 16 to the second conveyor path 17, the conveyor inlet 26 of the transfer conveyor 20 is brought into the stage 32 formed by the upper run 14 of the first conveyor 12, so that the leading edges 30 ′ seen in the conveying direction F Via the stage 32 conveyed printed products 30 run into 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. As soon as the desired number of printed products 30 to be redirected to the second conveying path 17 has entered the conveying inlet 26, the conveying inlet 26 is brought back into the retracted position 26 'by simultaneously pivoting the two conveying arms 22, 24 by means of the drive arrangement 28, the last being detected by the conveying inlet 26 Printed product 30 is pulled away under the subsequent printed product 30. The latter and all subsequent printed products 30 are then conveyed again along the first conveying path 16. The first conveyor arm 22 is mounted in a stationary manner in the region of its end 22 'which is effective for conveying. For this purpose, a shaft 38 is rotatably mounted on a frame 40 of the first conveyor 12 against supporting plates 42 projecting upwards, only one of which is shown in FIG. 1. On this shaft 38, two bearing plates 44, which run parallel to one another and are spaced apart from one another in the direction of the shaft 38, are pivotably arranged at one end, at the other end of which the bearing plates 44 'of the second conveyor arm 24 are pivotably supported. For this purpose, 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. On the bearing shaft 46, a deflecting roller 48 is further freely rotatable between the bearing plates 44, 44 '. Around this is the upper, conveyor-effective strand 50 of a conveyor belt 50' common to both conveyor arms 22 and 24, 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'. One more backup whale each ze 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, seen in the conveying direction F, in the central region thereof. 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. When the piston rod 60 is retracted into the piston-cylinder unit 60 ', the two conveyor arms 22, 24 are in an almost extended position, which corresponds to the working position of the conveyor inlet 26. By moving the piston rod 60 out of the piston-cylinder unit 60 ', the drive lever 58 is pivoted into the position shown in dash-dot lines (FIG. 1), as a result of which the two conveyor arms 22, 24 are pivoted together in a toggle lever-like manner in order to feed the conveyor 26 into the retracted position 26' spend.
  • As can be seen in particular from FIG. 2, the transfer conveyor 20 is made narrower in the direction perpendicular to the conveying direction F than the first and second conveyors 12, 16. In order not to impede the printed products 30 to be transported along the first conveying path 16, the stands in the conveying direction F seen on the right end shield 44 ', a support arm 62, on which the drive lever 58 extending outside the conveying area of the first conveyor 12 engages.
  • In order to hold the printed products 30 to be fed to the second conveyor 18 irrespective of the position of the conveyor arms 22 and 24 on the conveyor-effective strand 50, a pressure belt 64 is provided, the lower, pressing-on strand 64 'of which lies against 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 outwards 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. These are biased by spring assemblies 80 in the downward direction and thus against the end shields 44, 44 '. At the ends of the bearing members 74 facing away from the pairs of tabs 72, in the region of the conveyor inlet 26 and conveyor outlet 20 ', 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 a roller which is freely rotatably mounted on the further shaft 70 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 outward 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 fixed 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. When the conveyor arms 22 and 24 are pivoted relative to one another, the pairs of tabs 72 thus pivot relative to one another about the shaft 70, so that the length of the endless pressure belt 64 remains constant regardless of the position of the conveyor arms 22, 24.
  • The conveyor-active upper run 14 of the first conveyor 12, which is designed as a belt conveyor, runs from a deflecting roller 94, which is freely rotatably mounted on the frame 40 at the beginning 12 'in a known manner, viewed in the conveying direction F, rises slightly to a step roller 96 and from it 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.
  • Upstream of the step 32 falling in the conveying direction F, between the step roller 96 and the deflecting roller 94, a restraint device 100 is provided 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. The lower strand of the pressure belt 102 facing the upper strand 14 of the first conveyor 12, together with the latter, forms a conveying gap for the printed products 30 in order to prevent the printed product 30, which is not covered by the transfer conveyor 20, when the conveying inlet 26 is pivoted back from the working position into the retracted position 26 '' to prevent taking away.
  • A drive motor 114 is also located on the frame arranged, 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 the pressure belt 102 via a plurality of chain drives 118 'connected downstream thereof and also indicated by dash-dotted lines. Furthermore, the second conveyor 18 is driven in a known manner by the drive motor 114 via a chain drive 120, which is likewise only indicated by dash-dotted lines, via the shaft 38 and the chain drive 116. 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 at the same conveying speed v.
  • A feed conveyor 124, which is also designed as a belt conveyor, is connected upstream of the first conveyor 12 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.
  • For the sake of completeness, it should also be mentioned that 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 mode of operation of the conveyor device 10 shown in FIGS. 1 and 2 will now be explained with reference to FIGS. 3-7. In these figures, the area of the step 32 of the first conveyor 12 and the area of the feed entrance 26 of the transfer conveyor 20 are shown enlarged. The same parts as in FIGS. 1-2 are provided with the same reference numerals in these FIGS. 3-7.
  • According to FIG. 3, 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 step 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 end positions shown in FIG pivoted. In this waiting position 26 ″, the conveying entrance 26 is so far away from the stage 32 that the leading areas with the leading edge 30 ′ projecting freely over the stage 32 due to the inherent rigidity of the printed products 30 do not enter the conveying entrance 26, but instead pass under it , along the first conveying path 16. It should be noted, however, that at the stage 32 the leading area of each printed product 30 is lifted off from the preceding printed product 30 for a certain time.
  • As soon as printed products 30 are to be fed to the conveyor 18 defining the second conveying path 17, the conveying inlet 26 is brought into the working position shown in FIG. This is done by completely retracting the piston rod 60. The printed product 30, which is being conveyed via the stage 32 at this moment, reaches the feed inlet 26, the tongue 130 sticking between this printed product 30 and the preceding printed product 30. Since 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 lying on the upper run 14 following the step 32 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. When the conveying input 26 is shifted from the working position into the retracted position 26 ', which is done by extending the piston rod 60 of the piston-cylinder unit 60', the conveying input 26 is moved diagonally upwards from the stage 32 at a speed V1 , which is greater than the conveying speed v of the printed products 30 supplied. As a result, the last pressure detected by the conveying inlet 26 becomes The reiproduct 30 is pulled away from the subsequent printed product 30, the restraint device 100 preventing this latter printed product 30 from being carried along (see FIG. 6). Furthermore, this high speed V1 of retracting the conveyor input 26 reliably prevents the first printed product 30 to be fed back to the conveyor 126 from entering the conveyor input 26.
  • As shown in FIG. 7, 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 onto the second conveying path 17, can be brought back into the waiting position 26 "shown in FIG.
  • It should be noted that 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 retained even during the movement of the transfer conveyor 20. Since the wrap of the deflection roller 48 increases when the angle between the two conveyor arms 22 and 24 is reduced and the roller 54 'at the conveyor output 20' of the transfer conveyor 20 is driven at a constant circulation speed, the speed of the conveyor-effective strand 50 in the area between the conveyor inlet 26 becomes and the deflecting roller 48 is slightly enlarged when the conveying inlet 26 is brought into the retracted position 26 ', which additionally supports the separation of the successive printed products 30 at the stage 32 while maintaining the scale formation S in the area of the transfer conveyor 20.
  • With the device according to the invention, it is also possible to remove only individual printed products 30, for example waste, from the supplied scale formation S. For this purpose, the conveying input 26 is only brought into its working position for the time necessary to grasp this printed product 30.
  • It is of course also possible to design the transfer conveyor differently than shown in the figures; it would be conceivable to design each conveyor arm 22, 24 differently as a separate belt conveyor or as a guide for the pressure belt. Furthermore, the presence of a step is not absolutely necessary, since the transfer conveyor can pierce the scale formation S with a correspondingly designed tongue. If necessary, a restraint device 100 can also be dispensed with.
