Definitions

  • the invention relates to a transport system for supplying several roll stands arranged in a row with paper rolls according to the preamble of claim 1. Such systems are used in roll cellars of printing companies.
  • the sleeves must be removed from the area of the roll stands and collected in a sleeve container with which they can be used e.g. be removed at the end of printing.
  • a further parallel discharge track is provided, to which transfer rails lead from the roller stands, which are connected to the removal track via turntables.
  • the sleeves are transported individually by trolleys via this track.
  • the sleeve receptacle of the sleeve carriage cannot be tilted, so that it is not suitable for combined use with other conveying means and additional means are required to unload it if it is not done manually.
  • the sleeve carriage is not suitable for aligning the sleeves differently than in the longitudinal direction of the sleeve carriage, which limits the possible uses.
  • a gripper is provided which is guided along a rail suspended from the ceiling and which picks up the sleeve from a trough arranged next to a track section on a sliding platform on the roller stand and transports it to a sleeve container.
  • JP 62 157 160 A shows a separate roller conveyor for the sleeve disposal, which leads away from the roller stand in the axial direction. This solution is not suitable for disposal of sleeves from a larger system comprising a number of reel stands.
  • the invention is based on the object of specifying a generic transport system in which the sleeve disposal is achieved in a space-saving manner in such a way that it does not hinder the supply of paper rolls.
  • the solution should be particularly suitable for large systems.
  • the part which serves to dispose of the tubes is almost completely separated from the part of the transport system which serves to supply paper rolls.
  • the disposal part can be implemented in a confined space and, above all, hardly requires any additional space above the floor, so that the area which is problematic with regard to safety is little or not enlarged by it. It is also relatively simple in construction and inexpensive, if only because components that are dimensioned for heavy paper rolls are not used for the transport of the light sleeves, as in the known generic solutions.
  • a roll cellar of a print shop has several roll stands, which are arranged in a row. Three of these roller stands 1a, b, c are shown in Fig. 1.
  • Each roller stand 1a, b, c - one of which is described below as an example of a roller stand 1 (FIG. 2) - comprises a portal 2, in which an axis 3 is rotatably mounted, which is longitudinally opposite two spaced-apart the axis 3 has limited displaceable arms 4a, b, at the ends of which cones 5 are rotatably mounted.
  • a sleeve of a paper roll 6, on which a paper web 7 is wound, can be clamped between the cones 5 of the arms 4a, b lying opposite one another.
  • the paper web 7 is unwound and drawn off upwards via a guide roller 8, while the paper roller 6 rotates about a rolling axis 9 which passes through the cones 5 and is parallel to the axis 3.
  • the two roll-off axes 9 of each roll stand are thus aligned normal to the row of roll stands.
  • the roller stand 1 is assigned a sliding platform 10 with a track section 11 which is parallel to the unrolling axes 9 and which can be displaced along a pit 12 transversely to the unrolling axes 9.
  • the pit 12 lies for the most part under the roller stand 1, but extends beyond it on one side.
  • three light barriers 13 are arranged one above the other as part of an access guard, the lower 40 cm, the middle 90 cm and the upper one being slightly more than the largest roll diameter above the floor.
  • a transport system for supplying the roll stands of the series with paper rolls 6 and for disposing of the sleeve remaining after the paper web 7 has been unwound. It comprises a feed device arranged on a feed side of the row of roll stands and serving to feed paper rolls, each with a loading track 14 leading to the roll stand 1 and a transport carriage 15.
  • the loading track 14 is in each case parallel to the unwinding axes 9 of the roll stand 1 and leads to the side Edge of the pit 12.
  • the transfer platform 10 is located in a takeover position, the track section 11 is aligned with the loading track 14.
  • the transport system can further comprise a feed track (not shown) which is arranged parallel to the row of roller stands and from which the loading track 14, connected to it, for example via turntables, originate.
  • Transport trolleys 15 run on the feed track and the loading tracks 14.
  • the transport system comprises a disposal device for disposing sleeves 17, which is arranged on the opposite discharge side of the row of roller stands.
  • a transfer device is assigned to each roll stand 1.
  • it has a transfer track 16 which leads from the edge of the pit 12 to a feed point 18 and a conveyor device 19 which runs just past the feed points 18 along the row of roller stands.
  • the transfer track 16 is aligned with the track section 11, when the transfer table 10 is in a transfer position.
  • the loading track 14 is aligned with the transfer track 16, so that the takeover position and the transfer position of the transfer table 10 match each other.
  • the conveyor device 19 comprises a conveyor belt 21 arranged along the row of roller stands in a trench 20 or a row of such conveyor belts adjoining one another.
  • the trench 20 is covered by cover plates arranged at ground level, so that it is not an obstacle to one Walking and driving through the area.
  • cover 22 At the feed points 18 it has a cover 22, which can be opened and closed by means of a drive, for example an electric motor, the length of which is somewhat greater than the maximum expected length of a sleeve 17. It is normally closed, so that its surface is also level with the floor , but can be folded up to enable access to the conveyor 19.
  • the conveyor device 19 (FIG. 3) has an end section at the end of the row of roller stands, a conveyor belt 21 ', which is led from the trench 20 above the floor level through a wall 23 into an adjoining room in which it passes over the edge of a top open sleeve container 24, which is designed as a rolling trough of about 40m 3 , protrudes.
  • a sleeve carriage 25 On the transfer track 16 and the track section 11 runs a sleeve carriage 25. It has (Fig. 4a-c) a chassis 26 with a narrow base plate 27, the top of which is at ground level and on the underside wheels 28 are mounted on the transfer track 16 run. As a sleeve receptacle, an elongated trough 29 is tiltably mounted on a base 30, which in turn is mounted in the base plate 27 so as to be rotatable about a vertical axis.
  • the base 30 has a carrier 31 which is provided on the underside with support rollers 32 which run on a plate 33 supported on the base plate 27 and to which the trough 29 is connected by hinges 34.
  • a vertical axis 35 Formed on the underside of the carrier 31 is a vertical axis 35 which is guided through the plate 33 and the base plate 27 and is rotatably mounted in the latter, which is connected via a lever 36 to an eccentrically attached, downwardly projecting finger 37, which at its end carries an engagement roller rotatable about a vertical axis.
  • the total height of the loaded sleeve carriage 25 is just under 40 cm, so that, even if it is loaded with a sleeve, it does not trigger the lower of the light barriers 13 and there is no need for complex blind switching of the access protection when the sleeve carriage 25 passes through.
  • a buffer 38 is anchored as a stop, which limits the path of the sleeve carriage 25 and defines its position at the feed point 18.
  • an unloading device with a rotating device 40 is arranged in a pit 39 under the transfer track 16.
  • This comprises a motor 41, which is connected via an angular gear 42, which is also designed as a reduction gear, to a drive lever 43 which is rotatably mounted about a vertical axis in a bearing fixed in the pit 39.
  • the drive lever 43 has a longitudinal groove 44, in which the finger 37 engages with the engagement roller, so that the carrier 31 of the sleeve carriage 25 with the recess 29 can be rotated by means of the drive lever 43.
  • the unloading device (FIG. 4c) has a tipping device 47 installed next to the transfer track 16 with a plunger 48 which can be extended obliquely from below against the trough 29 and which is next to the transfer track 16 in the pit 39 in a fixed longitudinal guide 49 is slidably mounted.
  • the plunger 48 can act as a piston of a remotely triggered pneumatic cylinder be trained. Its tip is covered with slippery material.
  • the opening through which it is extended is covered by a hinged lid 50 which is level with the floor when closed.
  • the transfer table 10 is moved into the transfer position, whereupon the transfer track 16 e.g. sleeve car 25 parked at the feed point 18 drives onto the rail section 11 of the transfer table 10. This is then moved until the trough 29 lies below the sleeve, that is to say below the rolling axis 9 defined by the cones 5 which hold the sleeve.
  • the trough 29 as the sleeve receptacle is in the receiving position, with the longitudinal direction parallel to the rolling axes 9.
  • the arms 4a, 4b are pulled apart and at the same time the sleeve is pushed off the cones 5 by wipers, so that it falls into the trough 29.
  • the transfer table 10 is now moved back into the transfer position, whereupon the sleeve carriage 25 with the sleeve 17 moves from the rail section 11 onto the transfer track 16 and on to the loading point 18, where it abuts the buffer 38 (FIGS. 4a, 5a).
  • the finger 37 reaches the end of the lever 43, which is aligned parallel to the transfer track 16, and pushes into the groove 44 by the carriage covering the remaining path section up to the loading point 18.
  • the cover 22, which covers the conveyor belt 21 next to the feed point 18, is then folded up (FIG. 5c) and the trough 29 is turned around by opening the hinged cover 50 and extending the plunger 48 against the force of the tension spring 46 (see FIG. 4c) the axis defined by the hinges 34 is tilted against the trench 20, whereupon (FIG. 5d) the sleeve 17 rolls from the trough 29 onto the conveyor belt 21 in the trench 20.
  • the disposal system is controlled in such a way that overlapping of sleeves on the conveyor belt 21 is avoided.
  • the cover 22 is closed again, the plunger 48 is pulled back, so that the trough 29 assumes its upright position again under the action of the tension spring 46 (FIG. 5e).
  • the hinged lid 50 also closes. Finally, the base 30 with the trough 29 is turned back through 90 °, so that the longitudinal direction of the latter is again parallel to the transfer track 16 and the unrolling axles 9.
  • the sleeve carriage 25 is thus ready for a new use, while the sleeve 17 is conveyed through the conveyor belts 21, 21 '(FIG. 3) into the sleeve container 24 and thus disposed of.
  • the tipping of the trough could also be ensured by a suitable, for example wedge-like, forced guidance on the sleeve carriage, which causes the trough to perform a tilting movement during the last section of the rotary movement.
  • the rotation of the base with the trough could also be brought about by guiding the finger on the last part of the path in a backdrop that deflects it to the side.
  • the car could move to a waiting position in front of the loading point and later the moving to the loading point with rotation of the base and tilting of the trough could be carried out as a separate step.
  • a swivel arm with a trough instead of a sleeve carriage on a transfer track as a transfer device, which trough receives the sleeve under the roll-off axis and is swiveled and tilted by the swivel arm to the loading point.
  • the transfer device can also be arranged directly in the area of the roller stand, in which case the conveyor belt can pass under the roller stands.
  • the solution shown has the advantage of largely decoupling the sleeve disposal, so that the device parts serving the latter can easily be combined with other parts of the transport system and possibly. can also be retrofitted into an existing system.
  • another collecting device can be provided, e.g. a decoiler that removes any remaining windings from the tubes before they are collected in a tube container.
  • the transfer device is also arranged under the floor and lies under a floor-level cover 51 (FIG. 7, omitted in FIGS. 6, 9a-e), so that the disposal device enables Freedom of movement of people is not restricted.
  • It comprises a transfer conveyor 53 arranged in a trench 52, which leads from the side edge of the pit 12 to a sleeve receptacle, which is designed as a feed conveyor 54 and is mounted on a bogie 55, which is rotatable about a vertical axis in the bottom of a rectangular pit at the feed point 18 56 is stored.
  • the transfer conveyor 53 and the feed conveyor 54 are as flat conveyor belts.
  • optical sensors 57, 58 are mounted, offset in the longitudinal direction.
  • the feed conveyor 54 connects directly to the transfer conveyor 53 and projects with the end section carrying the sensors 57, 58 over the conveyor device 19.
  • the length of the feed conveyor 54 is significantly greater than that of the longest sleeve to be expected .
  • An unloading device also fastened to the bogie 55 comprises a slide 59 which can be pushed and retracted from the side via the feed conveyor 54.
  • an outwardly sloping ramp 60 is also fastened to the bogie 55.
  • the sliding platform 10 is designed as a sliding lifting platform with a lifting table 61 which, in addition to the rail section 11, also carries an elongated collecting device for a sleeve 17 on its edge facing the roller stand 1. It comprises a trough 62 or a trough which extends over the width of the lifting table 61 and whose bottom is coated with a lubricious material, and a transfer device with a driver 63 which projects into the trough 62 and can be pushed back and forth over the entire length thereof is.
  • the transfer device can e.g. comprise a drivable closed band which carries the driver 63 or a rodless pneumatic piston.
  • the transfer table 10 assumes the take-over position in which a transport carriage 15 loaded with a paper roll 6 moves onto the rail section 11 (Fig. 8a). Then it is moved against the roll stand 1 until the tub 62 is under the rolling axis 9 is located, which carries the sleeve 17 and then the lifting table 61 is raised from its basic position until the tub 62 is just below the sleeve 17 (FIG. 8b) and the same is thrown into the tub 62 without risk of damage. This is particularly important if it is a reusable sleeve.
  • the lifting table 61 is lowered again and the sliding platform 10 is moved further against the roll stand 1 in such a way that the paper roll 6 can be picked up by the arms 4a, b (FIG. 8c) and replaces the dropped sleeve 17.
  • the paper roll 6 is lifted from the transport carriage 15, the lifting table 61 is lowered into its basic position, and the sliding platform 10 is pushed back into the take-over position (FIG. 8d), so that the transport carriage 15 can change from the rail section 11 to the loading track 14.
  • the transfer table 10 then assumes a transfer position, which preferably again corresponds to the take-over position or is otherwise approached, in which the collecting device, in particular its trough 62, is aligned with the transfer conveyor 53.
  • the sleeve 17 is then moved by the driver 63 of the transfer device onto the transfer conveyor 53, which is also set in motion (FIG. 9a), and is transported by the same to the feed conveyor 54, which is also started and takes up its receiving position.
  • the sensor 57 When the front end of the sleeve 17 reaches a certain position near the end of the feed conveyor 54, this is detected by the sensor 57 and the feed conveyor 54 is stopped (Fig. 9b).
  • the sensor 58 is redundant. It responds when the sensor 57 fails for any reason and then causes the feed conveyor 54 to stop.
  • the bogie 55 is rotated by the feed conveyor 54 through 90 °, so that the latter assumes its unloading position (FIG. 9c). Then the slide 59 is pushed forward and pushes the sleeve 17 off the feed conveyor 54, so that it rolls over the ramp 60 (FIG. 9d) onto the conveyor belt 21 of the conveyor device 19 and is transported further by the same (FIG. 9e) to the sleeve container 24 ( Fig. 3) or another collecting device.
  • the sliding platform does not have to be designed as a sliding lifting platform, especially if the sleeves are not to be reused and it can therefore be accepted that they will be damaged when thrown off.
  • the collecting device can also be designed as a flat conveyor belt accompanied on both sides by side walls.
  • the transfer conveyor and the feed conveyor can be designed as troughs with a lubricious coating, with side conveyors or the like, which have at least one e.g. carry a retractable driver against spring force that pushes the sleeve over the track.
  • the feed conveyor can be designed to be tiltable, in which case the slide can be omitted.
  • the otherwise configured feed conveyor can also be stationary and at the end describe a quarter circle that leads to a straight end section parallel to the conveyor belt of the conveyor, which lies next to or above the conveyor belt, so that the sleeve is rotated and then moved up by a stationary slide the conveyor belt is pushed or tilts on the same and then falls down.
  • the disposal device can also be on the feed side, whereby it must of course be designed and arranged in such a way that no collisions with the feed device occur, in particular the conveyor device must be carried out under the loading tracks.
  • the sleeve disposal can be controlled by a master computer of the entire system. It is advantageous if the control is carried out in such a way that the sleeve receptacles of all transfer devices which have to dispose of sleeves are simultaneously transferring their sleeves to the conveyor device 19 and the conveyor belts 21, 21 'run between such transfers at least until a sleeve from the one of the feed points furthest from the sleeve container 24 and beyond that closest to it is promoted, as a reliable overlap of sleeves on the conveyor 19, which could lead to malfunctions, is avoided without great control effort.
