Definitions
- Winding device for roll cutting machines of the support roller type or the like Winding device for roll cutting machines of the support roller type or the like.
- the invention relates to a winding device with the features specified in the preamble of claim 1.
- Such winding devices are mainly used in slitter rewinder. While in reel cutting machines of the carrier roller type, in which the reel to be wound rests on one or two rotating support rollers with their own weight, so that the own weight of the reel to be wound ensures that the slip-free torque transmission of the carrier roller (s) to the reel to be wound If the required contact pressure is sufficient, it is necessary for roll cutters of the backup roller type - regardless of whether only the backup roller or the backup roller and the winding tubes of the rolls to be wound are driven in the direction of rotation - to ensure a sufficient contact pressure between the roll to be wound and the backup roll.
- the support arms or the support frames are pivotally attached such that the pivoting movement of these support arms or support frames follows the change in diameter of the roll during the winding process; in this case, the support arms or support frames are pivoted by means of a hydraulic cylinder, the contact pressure being able to be applied to the support roller via the hydraulic cylinder.
- the other way of applying the contact pressure is to hold the support arms or support frames in the same position during the entire winding cycle and to mount the clamping heads for the winding cores of the rolls to be wound up on a slide each, which is located on the support arm or .
- the support attached to the guide roller to or away from it can move, and, z. B. via a lever arm and a hydraulic cylinder pivoting the lever arm to apply a force acting in the direction of the support roller (contact pressure).
- the invention relates to both of the above options for letting the winding axis follow the change in diameter during the winding process.
- the sleeves or rolls, on which the partial webs created by longitudinal positioning are wound lie laterally on one or two support rollers arranged parallel to one another, preferably next to one another. Because of the space required in the axial direction of the support roller (s) for the support arms of the support rollers, the directly adjacent partial webs are wound on opposite sides with respect to the support roller (s). With such roll cutting machines, it is desirable to be able to wind rolls of the smallest possible web width if necessary.
- the object of the invention is to provide an improved center drive for the winding shaft for winding devices with the generic characteristics mentioned above, in particular for roll cutting machines of the backup roll type.
- the space requirement for the winding drive unit can be reduced particularly effectively by using a motor with the features of claim 2.
- support arms” or “support frames” are understood to mean any type of support elements which are suitable for carrying the roll to be wound up during the winding process in such a way that the roll to be wound up is rotatable and, preferably, on the support roller assigned to it is present.
- Such support arms or support frames preferably have a possibility of subsequently placing the roll which has been wound up on the floor or a means of transport.
- Such support arms or support frames are widely known in winding devices and therefore do not have to be explained in more detail.
- belt and “chain” are understood to mean any elongated transmission means which can be deflected along its longitudinal direction in a, preferably single, direction and, if appropriate, the corresponding opposite direction (180 °) by appropriately shaped deflection means.
- a transmission means which transmits the rotary movement is provided. If the drive wheel is not arranged on a movable or displaceable carriage or slide, the transmission means can also be a gear train, such as a gear transmission, under certain circumstances.
- “Circumferentially arranged traction means” are effective transmission means for driving forces in the sense of the invention, which can be deflected around deflection means in such a way that they can attack the carriage or carriage in essentially opposite directions.
- the aforementioned transmission means such as belts or chains can also be used for this purpose, whereby - as with the transmission means - belts include flat, toothed, V-belts or similar belts as well as any type of ropes and comparable elements that can withstand tensile loads are.
- the above-mentioned components to be used according to the invention are not subject to any special exceptional conditions in terms of their size, shape, material selection and technical conception, so that selection criteria known in the respective field of application can be used without restriction.
- Figure 1 is seen and shown schematically a winding device of a roll cutting machine of the backup roller type not shown in the rest in the axial direction of the backup roller, wherein a carrying carriage for a roll to be wound is shown in its two extreme positions.
- FIG. 4 shows an alternative embodiment of a winding device, viewed in the axial direction of the support roller (as in FIG. 1), both the winding position (in solid lines) and the depositing position (in dash-double-dashed lines) being shown;
- FIG. 5 shows a known three-phase external rotor motor suitable as a drive motor according to the invention in axial section. 1 to 3 as a whole with the reference numeral 100 shows the one side of a single winding device 101 and a support roller 30.
- This support roller can be part of a roller cutting machine of the support roller type which is known per se and is not specifically shown in the drawing which unwinds a wide web of paper or the like from a wide roll in a unwinding station, in a cutting station the wide web is longitudinally divided into at least two narrower partial webs, in two arranged on each side of the support roller 30 or more, in particular two, support rollers and the narrower partial webs are wound up from at least one take-up device 101 each.
- a support frame 10 of the winding device 101 is a known so-called roll-up frame, on which a slide 11 in straight guides 12 is slidably mounted.
- the carriage 11 rotatably supports a drive wheel 13 which, for. B. formed as a V-belt pulley and on the roller 25 opposite side of the carriage 11 protrudes laterally from this.
- the drive shaft 14 is rotatably inserted through the carriage 11 and carries on the roll 25 facing side of the carriage 11 a clamping head 15 (see FIG. 3), which in the open end of a winding tube 16 for the roll 25 to be wound up in a manner known per se can be frictionally or positively clamped.
- the roll-up frame 10 also carries a drive motor 17, which is a three-phase external rotor motor according to FIG. 5 in all the exemplary embodiments shown.
- the rotor which represents a rotatable active drive part 18 of the drive motor, rotates around a stator 19 fixed to the support frame 10.
- the outer diameter of the rotatable active drive part is corresponding Claim 2 - as large as the largest outer diameter of the entire engine.
- the rotor (drive part 18) carries holders on its outer circumference, e.g. B.
- a circumferential flange 20 to which a ring element 21 is fastened, which, together with the drive part 18, forms a driven wheel 22 which can be used as a V-belt pulley.
- the driven wheel 22 of the drive motor 17 and the drive wheel 13 on the slide 11 lie in a common plane and are encircled by a rotating drive belt 23, which in this exemplary embodiment is designed as a V-belt, in the sense of a transmission.
- a tensioning wheel 26, which can be displaced with its axis on the support frame 10, ensures the required tightness of the drive belt 23.
- deflection elements 27 and 28 are provided on the support frame 10 as rotatably mounted rollers, which are also designed as V-belt pulleys are and are also in one plane with the drive wheel and the driven wheel. In this way, the winding drive unit can work in any position of the carriage 11 along the guide 12. Further deflection elements 29 and 31 in the form of rollers or V-belt pulleys rotatably mounted on the carriage 11 allow the length of the drive belt 23 to be kept constant in every working position of the carriage 11, the angle of wrap of the drive belt 23 around the drive wheel 13 also remaining unchanged.
- the function of the winding drive unit is now such that the winding process begins in the position of the carriage 11 shown in solid lines on the left in FIG. 1, in which the beginning of the partial web 24 to be wound up by looping and / or sticking or the like to the winding tube 16 is attached and the winding tube rests on the support roller 31.
- the partial web 24 is now wound up, with the roll 25 already wound increasing continuously in diameter, so that the carriage 11 is shifted to the right in accordance with the increase in diameter (in the drawing) until he has reached the dash-dashed end position in which the roller 25 has reached its desired end diameter.
- the carriage is displaced by means of deflection means 33 to 35 designed as rotatable rollers or gearwheels and a traction means 32 designed as a chain, which is arranged with one end above the guide 12 at an attachment point 38 of the carriage 11 and with its other end at one below the guide 12 Attachment point 39 of the carriage 11 engages the carriage 11 in the direction of pull. Due to the fastening points 38 and 39 located on both sides of the guide 12, the tilting moment exerted on the guide remains constant in both working directions.
- a drive motor 37 is provided for driving the traction means 32 and a tensioning wheel 36 for tensioning the chain.
- the entire support frame 10 is pivotally mounted about a swivel axis 40 and by means of a piston / Cylinder arrangement 41 can be pivoted between these two positions.
- the position of the support arm or support frame 10 changes in accordance with the increase in the diameter of the roll 25 to be wound.
- the support arm or support frame 10 is in a manner known per se by means of a piston / cylinder arrangement 41 a Pivot axis 40 is pivotable, this pivot axis and this piston / cylinder arrangement also taking over the function of roll bending.
