Definitions

  • the invention relates to a device for moving an unwinding roll produced on a machine for producing fibrous webs between at least two handling stations, comprising a transport unit guided on at least one guide and a device for detecting the position of the transport unit in the guide.
  • Apparatus for moving a supply reel made on a machine for producing fibrous webs between at least two, preferably stationarily arranged handling stations comprising a, at least one guide guided transport unit and means for detecting the position of the transport unit in the guide are in a variety of designs known.
  • Under handling station is generally understood a means for receiving, storage and movement of a number of Abwikkelrollen, which are produced successively in time by a machine for the production of fibrous webs understood. This is often stationary.
  • the transport unit is formed by a Tambourtransportwagen. This can be a handling station which is designed as an independently movable unwinding roller transport carriage or a transfer carriage which can be moved directly between two stationarily arranged handling stations and handles the winding rollers between them.
  • the transfer carriage is usually movable between the handling stations of a workstation, while the unwinding roller transport car between individual, at least one handling station having and parallel to each other arranged workstations is movable.
  • Unwinding roller transport carriage and transfer sled are each movable along a guide associated therewith.
  • the leadership of the unwinding roller transport carriage is usually arranged perpendicular to the leadership of a transfer carriage.
  • systems are known which detect the positions of the transport unit over the entire travel distance, which are provided for detecting the driving range area initiators and the detection of the position in the area via position sensors. The number of detection devices required for position detection is very high.
  • the invention is therefore an object of the invention to provide a way of accurately detecting the position of a transport unit in the apparatus for moving an unwinding, which is characterized by a small number of required sensors, a simple and secure detection capability of the position of the transport device and also little susceptible to contamination.
  • An apparatus for moving an unwinding roll produced on a machine for producing fibrous webs between at least two handling stations comprising a transport unit guided on at least one guide describing the path and a device for detecting the position of the transport unit in the guide, is characterized in that Device for detecting the position of the transport unit in the guide arranged parallel to the guide stationary measuring rail system each having a, a handling station associated, extending over the effective range of these and spaced in the direction of movement of the transport unit to form free spaces arranged measuring rails, each measuring rail a run - or driving range of the transport unit characterized and the transport unit has at least one detector, by means of which in cooperation with the respective measurement rail, the position of the transport unit can be determined on its theoretically possible path.
  • the solution according to the invention enables an easily manageable measuring system arranged and operating outside the working area of the transport unit. With this can be detected both the area in which the transport unit is located as well as the exact position of these are determined in the respective area with great accuracy.
  • the clearances between the individual measuring rails of the measuring rail system can be identical or different via the displacement path. If the free spaces are different, it is also possible to dispense with a separate directional differentiation and to deduce the direction of travel from the sequence of free spaces.
  • the system measuring rail / detector works together without contact. Due to the parallel arrangement of the measuring rail to the actual guide, the system is insensitive in the Regard to the actual mode of operation of the transport unit and to pollution.
  • the detector unit comprises at least one device for detection, in particular a sensor. This is preferably based on optical detection. Other systems are conceivable.
  • the detection of the position according to the invention is suitable for any type of transport units in devices for moving material web rolls in machines for producing fibrous webs.
  • the transport device may be formed by a unwinding roller transport carriage or a transfer carriage.
  • a measuring rail system according to the invention is associated.
  • the solution according to the invention is particularly suitable for detecting the position of an unwinding roller transport vehicle, which is movable between individual workstations, comprising in each case at least one handling station.
  • the guidance is usually via rail systems that extend over several meters in the hall floor. These are also passed by other means of transport. In this case, the free spaces between the measuring rails can be passed in an optimum manner without affecting the measuring rails adjacently associated therewith.
  • the design of the measuring rails is independent of the actual guides of the transport units. In the simplest case, these can comprise at least one pair of rails.
  • FIG. 1 illustrates in schematic simplified representation based on a side view of an apparatus 1 for moving an unwinding roll 2 produced on a paper or board machine between at least two handling stations A and B by means of a transport unit.
  • the handling station A is arranged stationary, that is stationary, and has two support rails 4.1, 4.2 arranged parallel to one another on a chair 3 of known type for supporting the unwinding roll 2.
  • the handling station B can be embodied as an independently movable unwinding roller transport car 5, which has both carrier means 6 for the unwinding reel 2 and locking means 7 for the unwinding reel 2 and functions as a transport unit.
  • the unwind roller transport carriage 5 can be brought at least temporarily to the transfer of the unwinding roller 2 to the stationarily arranged handling station A, preferably by means of a guide F1 in the form of a known rail system or by means of an inductive loop system. Between the two adjacent handling stations A and B means 8 for supporting the unwinding roll 2 are provided.
  • a further stationarily arranged handling station C is provided, which is arranged at the other opposite end of the stationarily arranged handling station A and which in turn has locking means 9 for the unwinding roller 2.
  • the movement of the unwinding roll 2 takes place by means of a movable transfer carriage 10 which grips the two ends 11.1, 11.2 of an unwinding roll 2 by means of a respective fork 12.1, 12.2 and can move them.
  • the transfer slide 10 of the device 1 also acts as a transport unit and is on the outside in a guide F2 on the chair 3 of the handling station A of FIG. 1 guided.
  • the transfer carriage 10 has a drive unit 14 and a pivotable driving lever 17.
  • the driving lever 17 is mounted approximately in its center of gravity S on the frame 13 and by means of a, here only indicated pivoting device 18, pivotable.
  • the actuator for the pivoting device 18 may be electromechanical, pneumatic or hydraulic nature.
  • the mounted on the frame 13 pivoting driving lever 17 has two cantilevered forks 12.1 and 12.2, which protrude on both sides of the frame 13 and so take over the unwinding roll 2 from the adjacent or a transfer of the unwinding roll 2 at the two adjacent handling stations B, Allow C by means of forks 12.1 and 12.2.
  • Each of the forks 12.1, 12.2 of the pivoting driving lever 17 has at least two spaced, axially parallel to the unwinding roller 2 aligned and rotatable contact rollers 19, which optionally with a friction-reducing coating, such as polytetrafluoride ethylene, are provided.
  • the two forks 12.1, 12.2 of the pivoting driving lever 17 are at least in a movement position below the support rails 4.1, 4.2 of the stationarily arranged handling station A and / or the means 8 for supporting the unwinding roller. 2
  • the energy transmission to the devices 14, 18 of the transfer carriage 10 is carried out in each case via at least one conductor line, a tow cable, a cable drum and / or the like, and the data exchange to a control device 20 and the transfer carriage 10 via at least for example one Radio connection, a data light barrier, a bus loop, towing cable, a cable drum and / or the like.
  • the further second handling station B is an independently movable Abwikkelrollentransportwagen 5, which has both the support means for the unwinding and locking means 7 for the unwinding roll 2 and at least temporarily for transferring the unwinding roll 2 to the stationarily arranged handling station A can be brought.
  • the handling station A acts as a workstation.
  • the unwind roller transport carriage 5 is guided in a guide F1 to the handling station A.
  • the guide F1 is perpendicular, that is arranged at right angles to the arranged within the handling station A guide F2 for the transfer slide 10.
  • the movement of the unwind roller transport carriage 5 via a controller.
  • the control device can also be used for the transfer slide 10, so that a common control device 20 is available.
  • a device 22.1, 22.2 for detecting the exact positioning in the form of a measuring rail system 23.1 for the guide F1 and 23.2 for F2 is used for this purpose.
  • a measuring rail system 23.1, 23.2 is installed in each case parallel to the guides F1 and F2.
  • the individual measuring rails 23.11, 23.21, 23.22 are stationary.
  • the measuring rails 23.11 to 23.22 are readable on the wheels or on the counterpart 26 to the guide F1 and F2 detector units 25.
  • the detection is preferably contactless. Optical sensors are used.
  • the measuring rails are designed as stationary rails which theoretically form individual driving ranges over the length of the theoretical travel path S.
  • FIG. 2 illustrates, by way of example, a theoretically possible travel path S theoretically of an unwinding roller transport vehicle 5, which here comprises, for example, three areas I to III, each of the areas containing a handling station A, A1, A2.
  • I corresponds by way of example to A
  • II corresponds to A1
  • III corresponds to A2. It is now necessary to position the unwind roller transport car 5, in particular the individual rail-bound vehicle, precisely in these areas relative to the individual handling stations A, A1, A2.
  • the individual areas I to III are assigned to different handling stations.
  • the individual measuring rails 23.11, 23.12, 23.13 of the measuring rail system 23 are each arranged at a distance from one another, here via the clearances 24.11, 24.12, which are in the displacement or movement direction from the area I to the area III, between the area I and the area II and between the area II and III are provided.
  • the sizes of the free spaces 24.11, 24.12 can be identical. For better range recognizability, however, these can also be made different sizes.
  • Each of the areas is characterized by a position detection.
  • the individual positions are in the direction of travel with x1 for the beginning of the first area I, x2 characterized for the final position in the driving range I.
  • the positions are denoted by x3 and x4.
  • the region III is characterized by the initial position x5 and the end position x6.
  • the ranges are over the difference of the writable in both positions. It can be seen that 25 positions x2 - x3, that is the gap 24.11 and x4 - x5 are not recognized by the detectors 25 for the space 24.12 and detected in the control device 20 as between the areas I, II or II, III present , Since the measuring rail system 23 is not continuous, different areas can be detected in these areas I to III.
  • an area detection and a position detection are carried out.
  • the area recognition takes place by recognizing the assignment or the position of the rail-bound vehicle in the driving ranges I to III.
  • the position detection directly contains the position within the respective area I to III.
  • the corresponding detectors 25 are arranged on the wheels for this purpose and determine the position via, for example, the traveled travel path starting from an initial position. In this case, the respective car or the rail-bound vehicle is spent at the beginning, for example, in a position 0. This corresponds to the starting position, for example the first driving range x1. If not, then the car is moved to this position.
  • a movement over the first range follows via the drive and the measuring rails 23.11, 23.12, 23.13 are read.
  • 23.11, 23.13 position detection means may be arranged on the stationary measuring rails, which characterize the individual positions and are read in a corresponding manner by the detectors 25. The exact position determination can be done differently. This depends on the individual detected quantities.
  • the position is read directly from the measuring rail 23.11, 23.12, 23.13, as in FIG. 3a clarified. In this case, every position characteristic xn with n> 0 exists only once.
  • FIG. 3b is determined via an initial position value x1, x3, x5 or return x6, x4, x2 the driving range and then within the driving range I to III respectively the position.
  • Other possibilities are conceivable.
  • the system according to the invention due to the interruptions, in particular clearances between the measuring rails in these is also passable, which is particularly important for larger roads of considerable importance. Furthermore, even after a power interruption, the position of the unwinding roller transport vehicle can be clearly determined by approaching the next measuring rail.
  • the means for detecting the position of the individual measuring rail can be designed in many forms. Preferably, systems are used which allow a unique position detection.
