Definitions

  • the invention relates to a mandrel according to the preamble of claim 1 or 2.
  • US 41 49 682 A, US 49 51 894 A and US 4715 553 A are mandrels Known for rotatable storage of paper web rolls, as they are Rotary printing machines are used. At the mandrels are each Ejector devices are provided with which the sleeve on which the paper web is wound, can be stripped from the mandrel. When introducing the Mandrel in the sleeve are provided on the ejector device Spring elements preloaded elastically. If the mandrel for changing the Retracted paper web from the sleeve, the bias of the spring elements ensures making sure the sleeve is ejected from the two by each other opposite mandrels is stripped.
  • a disadvantage of this type of design of the ejector device is that the force with which can be stripped from the mandrel, by the design of the Spring elements is limited. In addition, the preload of the spring elements at Inserting the mandrels into the sleeve can be overcome.
  • a mandrel in which between the Stop flange of the mandrel and the sleeve a slidable ring is arranged, the can rotate together with the mandrel.
  • an Actuating device is provided which is fixedly attached to a frame.
  • the Actuators are provided with claws, the ring being in one position Claws, namely the rest position, can rotate freely and do not engage the claws is.
  • the actuating device is actuated, the claws are against the ring pressed so that the sleeve can be stripped from the mandrel.
  • a disadvantage of the actuating device known from DE 28 14 338 A1 is that the ejector device has a large construction volume due to the mechanical drive needed.
  • US 55 31 398 A discloses a stripping device for a roll of material with a rotating part on the roll of material and a fixed part of one Hydraulic cylinder actuated part.
  • the rotating part is in the working position one side and in the rest position on the other side of the non-rotating part.
  • WO 99/28218 A1 shows a push-off device for pushing sleeves a thorn.
  • a pressure-actuated piston is provided, which is operated by means of magnets is connected to the pusher.
  • the invention has for its object to provide a mandrel.
  • a pressurized piston is used in the ejector device. Since that pressure-carrying fluid, for example compressed air or hydraulic fluid, through channels geometry of any design can be guided to the displacement above the piston can be, mandrels in a very compact design are possible. You can also by a correspondingly high working pressure generates very high wiping forces become.
  • pressure-carrying fluid for example compressed air or hydraulic fluid
  • the piston is designed to act only on one side.
  • the piston is like this to arrange that the piston is driven to strip the sleeve with the fluid can be.
  • elastic Spring elements such as coil springs, are used.
  • the Training of the ejector device should therefore be chosen so that the second Part between a rest position and at least one working position are adjusted can. In the rest position, the first part is completely separated from the second part by a gap separately while he comes to the system in the working position on the second part, so that Forces for actuating the second part can be transmitted.
  • To reset the second part from at least one working position in the Magnetic elements can be used particularly advantageously in the rest position.
  • the of attraction forces emanating from a magnetic element act without contact across an air gap and can automatically in a particularly simple manner withdraw the fixed second part, for example an actuating piston.
  • a mandrel 01 is shown, which is shown in a broken frame 02 an otherwise not shown reel changer is attached.
  • the frame 02 firmly connected housing 03 of the mandrel 01 is with the rolling bearings 04; 06 one multi-part shaft 07 rotatably mounted.
  • the multi-part shaft 07 extends to the Outside of the housing 03 and forms a clamping cylinder 08 on which one schematically illustrated sleeve 09 can be fixed.
  • the toggle levers on the by means of disc springs and compression springs provided jaws 11 pressed radially outwards.
  • an adjusting element 12 e.g. B. an actuating shaft 12 in one Hollow shaft 13 can be adjusted axially, so that the clamping jaws 11 by positive Engagement of the expansion elements 14 are pressed outwards.
  • the sleeve 09 carries a rolled up web, e.g. B. paper web.
  • a used sleeve 09 from the scraper ring 10 is 01 on the mandrel an ejector device with several control elements 16, z. B. rotatable parts 16, e.g. B. ejector pin 16 is provided.
  • the ejector pin 16 are so on the Hollow shaft 13 arranged that the one end of the scraper ring 10 on the end face the sleeve 09 can come to rest.
  • Ejector pin 16 extended synchronously with the scraper ring 10 and press the Sleeve 09 relative to the clamping cylinder 08 to the side. It should be noted that the Ejector pin 16 and the scraper ring 10 on the hollow shaft 13 are axially displaceable are stored and together with the hollow shaft 13 in the housing 03 about the central axis 17th rotate.
  • a non-rotatable part 18, for. B. a circular piston 18 used the pressure line 19 with pressure medium can be applied.
  • the operation of the actuation of the ejector pin 16 through the piston 18 with reference to the drawings Fig. 2 and Fig. 3, the detail X 1 enlarged in the detail, explained.
  • FIG. 2 shows the piston 18 in cross section and the right end of the Ejector pin 16.
  • the piston 18 together with the housing 03, an intermediate piece 21 and the outer ring of the roller bearing 06 is fixed relative to the frame 02, whereas the Ejector pin 16 together with the hollow shaft 13 about the central axis 17 of the Mandrel 01 can rotate. This ensures that the piston 18 with simple means, which are designed in the manner of piston rings, are sealed can.
  • Fig. 2 the piston 18 is shown in its rest position, in which the ejector pin 16 and the piston 18 are separated by a gap 22. In the resting position of the Piston 18 can the ejector pin 16 wear and resistance around the Rotate center axis 17.
  • the piston 18 is with sealing rings 24; 26 sealed against the housing 03 or the intermediate piece 21, so that by Actuation of the pressure line 19 with pressure medium in the direction of Ejector pin 16 directed force can be exerted.
  • the piston 18 is shown in a working position.
  • the piston 18 against the ejector pin 16th pressed so that it in turn can strip the sleeve 09 from the clamping cylinder 08.
  • the pressure medium from the pressure line 19 drained so that the piston 18 no longer act compressive forces.
  • the permanent magnets 23 provided on the piston 18 act on the piston 18 a rightward magnetic force, the return of the piston 18 over the gap 29 caused.
  • the piston 18 At the end of the actuation of the ejector pin 16, the piston 18 a rest position, as shown in Fig. 2, and is through the gap 22nd separated from the ejector pin 16.
  • the end positions of the piston 18 are queried by means of initiators 30.
  • actuating shaft 12 the represents such rotatably mounted actuating element for actuating the Clamping jaws 11 shifted to the left by means of an axially adjustable piston 31 only can be.
  • pressure medium is introduced into one of the pistons 31 via a pressure line 32 and the cylinder space formed in the housing 03. The pressure medium ensures that the piston 31 is shifted to the left and so by acting on the End plate 33 adjusts the actuating shaft 12 so that the clamping jaws 11 result can be operated.
  • the springs 34 provide for Resetting the actuating shaft 12 so that the piston 31 passes through the end plate 33 is pushed back.
  • the actuation shaft 12 is reset by end stops limited so that the piston 31 through the end plate 33 only up to a certain Point, namely the rearmost working position, can be pushed back.
  • the piston 31 is still on the end plate 33, which is because of this wear occurring in the event of a relative movement between end plate 33 and Piston 31 is undesirable.
  • To avoid this wear are on the of the End plate 33 facing away from the end of the piston 31 magnetic elements 37, z. B. Permanent magnet 37 is provided, by the magnetic forces of the piston 31 in a Rest position can be reset, in which the piston 31 no longer on the End plate 33 comes to rest.
