Definitions

  • the proposed device relates to the releasable holding of core tubes, rolls of paper, foil, plastics, metals, fabrics or the like with at least two displaceable or changeable in their radial positions on at least one profile piece or the like Clamping segments.
  • Devices of the aforementioned type are usually used to support sleeves in web-processing machines in such a way that webs of paper, foil, metals, plastics, fabrics or the like wound on these sleeves, core tubes or the like are unwound from these sleeves can to run to a processing machine.
  • Such devices can also be used to rotatably support core tubes or sleeves on which such webs can be wound coming from a processing machine.
  • the rolls in the machine must be able to be held so that they can be rotated centrically as precisely as possible.
  • so-called expansion clamping shafts or expansion clamping heads are often used, in which any components are moved in the radial direction of the entire device, for example can that the core tubes can either be tensioned from the inside or loosened as desired and removed from the rest of the machine.
  • clamping heads which are movable in the radial direction for clamping or releasing, are often moved along somewhat oblique, that is to say essentially wedge-shaped, paths, in order in this way to be able to be displaced either into the so-called clamping position or into the so-called releasing position.
  • a device for releasably holding core tubes in which a plurality of eccentrics are arranged in such a way that, in the event of a relative rotation between the essentially internal device and the clamping elements movable in the radial direction of the device, the clamping elements are then radial be moved when the eccentric assigned to the respective clamping element is rotated accordingly.
  • this device contains at least two radially displaceable clamping segments or clamping elements which are attached to their carrier in such a way that they can be clamped in an extreme position.
  • Roller sleeves, core tubes or the like, which are used in processing machines, that is to say are rotatably held therein, are however often subjected to changing forces.
  • the object is therefore to improve the device of the known type in such a way that it cannot loosen undesirably during operation with simple and automatic operation.
  • the device proposed according to the invention it should be possible with the device proposed according to the invention to be able to clamp or remove core tubes, sleeves, coiled rolls or the like automatically, for example in a roll cutting and winding machine.
  • This object is achieved by an effective brake in each radial position of the clamping segments, counteracting a displacement of each clamping segment, a movable locking claw fixed in the immediate vicinity of the machine frame, a pin, a ratchet or the like and an adjacent one on the outside of the holding device , the spigot, the ratchet, locking claw or the like. It is also proposed that the pin, the ratchet, the locking claw or the like can be released if necessary, for which purpose at least one electromagnet, pressure medium cylinder or the like can be used per pin, ratchet, locking claw or the like.
  • the brake used can be a friction brake with at least one friction lining, preferably a multi-disk brake, wherein the friction linings can be arranged concentrically with the drive shaft.
  • a tensioning device is created with a simple, robust and inexpensive construction, with which core tubes, sleeves, rollers or the like can also be automatically held sufficiently when the roller or its holder device is in operation only slight tensile forces on the part of the web to be wound up or unwound, or even forces which ultimately could lead to an undesired release of the tensioning device.
  • Such forces could occur, for example, by changing the tension to which the web-like material is subject, for example at the beginning or at the end of an acceleration process, or also during the so-called emergency stop, that is to say a particularly powerful braking process.
  • a (drive) shaft 2 is rotatably held in a known housing part 1, a swivel arm for holding coiled rolls or the like, or some other type of appropriate holder with the aid of bearings 3 and 4.
  • a rotating part 5 At the left end of the shaft 2 in FIG. 2 there is a rotating part 5, which can consist of the same component as the shaft 2.
  • a flange 6 is connected to the rotating part 5.
  • the proposed device can therefore be analogous to that of our earlier patent application DE-A-37 00 472.7, to which reference is made for the purpose of supporting the description and for further explanation.
  • the rotating part 5 rotates together with the shaft 2. It can have a circular cross-section or any other appropriate cross-section, for example a so-called multi-spline profile.
  • end of the rotating part 5 are radial, i. H. in FIG. 2, for example, upward or downward adjustable clamping segments 7 are attached.
  • the proposed device also has guide pieces 8, with the aid of which the clamping segments or parts of the clamping segments 7 can be guided both in the radial and in the circumferential direction. All guide pieces 8 are fastened, for example, with the aid of screws 9 on an annular disk 10, which in turn is pushed onto the flange 6 in such a way that it can be turned relative to it. In this way, it is possible to move the clamping segments 7 radially, ie in the direction of the arrow 12, by rotating the shaft 2 and correspondingly rotating the profile piece (s) 11 firmly connected to the shaft 2 with guide pieces 8 secured against rotation. In this way, the respective core tube 13, the sleeve, the wound roll or the like can be gripped and held from the inside by the tensioning segments 7. In addition, with the aid of known retraction devices, not shown, it is possible to move the tensioning segments 7 back in the direction of the arrow 12 towards the inside of the device in order to release the core tubes or the like again, if this should be desired.
  • the disc 10 is connected to an annular disc 15 by means of screws 14. Between the disk 10 and the washer 15, a further ring 16 is inserted into a corresponding recess, for example the washer 15, which can be connected to the shaft 2 in a rotationally fixed manner and can rotate together with it.
  • This connection can take place, for example, in that a pin 17 is inserted radially into the shaft 2 and is fastened therein, which engages in a corresponding recess 18 located on the ring 16.
  • a simple coupling is created, which allows the ring 16 to be rotated by and with the shaft 2 as it rotates, on the other hand in the axial direction, i. H. in the direction of arrow 19, relative to the shaft 2 is movable within limits.
  • a clutch lining 20 is inserted between the ring 16 and the annular disk 15. Both a clutch ring 21 and a pressure plate 22 are inserted between the ring 16 and the disk 10.
  • the dimensions of the clutch lining 20 and the clutch ring 21 and their materials are preferably identical to one another.
  • a brake preferably a multi-disc brake, is formed with friction linings concentric with the drive shaft 2 and consisting of the clutch lining 20 and the clutch ring 21, which counteracts a relative movement of the shaft 2 and the tensioning segments 7.
  • the resulting inhibition occurs not only at a certain radial position of the clamping segments 7 or a clamping segment 7, but at any radial position of the clamping segments 7.
  • the brake consisting of the clutch linings and their associated parts and the braking forces caused by the compression springs 24 must be overcome.
  • These braking forces can be selected or adjusted during assembly of the device in such a way that the tensioning segments 7 cannot undesirably slide radially inwards due to vibrations, acceleration or deceleration forces in the machine. In this way it is prevented that the core tube 13, the wound roll or the like is not loosened undesirably during the operation of the device.
  • a toothing 25 is preferably incorporated obliquely into the washer 15.
  • a locking claw 26, which corresponds to the toothing can intervene if necessary in that it is moved by an electromagnet 27 or a pressure cylinder in the direction of the arrow 28 can be moved. If, for example, the locking claw 26 is shifted to the left in FIG. 2, then the locking claw 26 engages in the toothing 25 and prevents the annular disk 15 and thus the entire, exciting and engaging device that engages the core tube or the sleeve 13 from rotating.
  • the electromagnet 27 or a pressure medium cylinder corresponding to this is fixedly attached to the housing part 1.
  • a toothing 25 another device can be selected which is able to temporarily prevent the clamping device in question from rotating. This can be done, for example, by means of a parking brake, or else in that instead of a locking claw 26, a simple round pin can be inserted into a corresponding hole made in the annular disk 15. If the annular disc 15 is prevented from rotating, for example by means of a locking claw 26 which is engaged in the toothing 25, the shaft 2 can be rotated against the brake represented by the clutch lining 20 and the clutch ring 21 or the forces caused by them when a corresponding torque is introduced.
  • the proposed device now makes use of the idea of using the torque already available per se for the tensioning process, which makes it possible, on the one hand, to automatically tension when the locking claw 26 is pushed in, ie in such a way that human assistance for this process is no longer necessary, and that on the other hand the drive torque available per se is also used for the process of gripping and tensioning the core tubes.
  • the locking claw 26 is in turn attached in the immediate vicinity of the holding device to the housing part 1, the pivotable holding arm or the like, so that the path for snapping into the receiving device formed by the toothing for the locking claw 26 is very short.
  • the locking claw 26 can be released either by displacement in the direction of the arrow 28 relative to the housing part 1 or else in that a correspondingly differently arranged device, which can be pivoted, for example, about a fixed pivot point, pivots out of the receiving device for the locking claw represented by the toothing 25 becomes. If necessary, a plurality of locking claws 26 can also be arranged around the outside of the ring disk 15, ie, since this part is generally circular, in the vicinity of the outer circumference of the ring disk 15. These multiple Locking claws can then be made effective or ineffective by a single actuation, for example with the aid of a push button or a remote control pulse.
