Definitions

  • the invention relates to a device for connecting the end of a material web running from a first winding roll to the beginning of the web of a new winding roll that is exchanged for the first winding roll, according to the preamble of claim 1.
  • splice devices which connect the end of the material web running to a processing machine with the start of the web of a new roll. If the machine contains fixed holding devices for the winding rolls, the remaining roll is cut off when the processing machine is at a standstill, the cut end of the running web is held in place and, after the separated residual roll has been removed and a new winding roll has been inserted, is attached, for example glued, to the new roll.
  • a device In order to automate the splice process, a device is known from DE-PS 34 40 107, which has a driven device for storing a supply of web material of the running material web, a cutting device for severing the running material web and between the cutting device and the storage device Has suction roller, which receives a part of the stored stock of web material and brings into pressure contact with the outer circumference of a new roll in order to produce an adhesive connection with the beginning of the new roll, which is provided with an adhesive strip.
  • the suction roll is arranged on a swivel arm which has a pivot point above the maximum outer diameter of the new winding roll and which extends substantially horizontally in the rest position.
  • the device shown there is structurally complex because it requires separate drives for clamping the running web, the movement of the storage device, the rotating and swiveling movement of the suction roll, the cutting device and for switching on the suction air.
  • the cutting knife must be moved separately from its cutting position, since this is in the area of the running web during unwinding.
  • These necessary drives require a complex control device.
  • this device is less suitable for use on reel unwinding machines which are arranged directly from a subsequent reel cutting and winding machine.
  • a generic unwinding device which contains a separating device separate from the splice element.
  • the separating device assumes a working position which clamps the web to the splice element and can be returned to a rest position after the web has been separated by lifting the empty roll through the unwinding position.
  • the separating element has to be moved separately from the cutting position and requires a lot of space.
  • the invention has for its object to provide a generic device that can be used with the least possible design and control engineering effort even in confined spaces.
  • the elements for severing the running web, for holding the web end created in this way and for pressing against the outer circumference of the new reel in place are realized in a single splice element, which means that the design effort, e.g. the number of drives is reduced.
  • a further advantage is that the device according to the invention can be used in unwinding machines with a different withdrawal direction of the paper web, even with a changing withdrawal direction.
  • this contains a rotary drive according to claim 3, the torque of which is adjustable.
  • the movement of the splice element required for the splice process is advantageously carried out by means of swivel levers (patent claim 4) in order to be able to glue the beginning of full rolls with large differences in diameter to the running web.
  • the splice element is linearly movable in lateral guides. An exclusively linear movement is possible, but limits the diameter of the new rolls to be glued to a certain area.
  • the combination of a linear and a pivoting movement by means of linear guides attached to pivoting levers is preferred, since it makes the contact and pressing point of the splice element on the full roller variably selectable within a large range. This is particularly advantageous if both winding rolls with web take-off are unwound from above and from below.
  • the embodiment with the suction zones arranged on both sides next to the separating element according to claim 6 is able to establish the connection both when the web is withdrawn from above and when the web is withdrawn from below.
  • the clamping element according to claim 7 enables an automated change from a web take-off from above to a web take-off from below and vice versa.
  • Claim 8 contains a particularly advantageous embodiment of the clamping element.
  • Claims 9 and 10 contain a splice element with an advantageous web separating and web holding element, in which the newly created web end is held mechanically with needles.
  • the mechanical holding of the web can alternatively or additionally, e.g. B. for stiff types of paper, used for holding by means of suction air.
  • Needles arranged on both sides of the separating element e.g. according to claim 11) enable use in changing directions of rotation of the supply rolls.
  • the elastic outer surface of the splice element according to claim 12 ensures a uniform contact pressure over the entire web width.
  • the splice element can be divided over the working width in order to adapt to a non-straight course of the surface of a full roll.
  • FIG. 4 the side view of an embodiment with only slightly inclined path of the withdrawn web
  • 5 and 6 a side view of an embodiment which is suitable for use in web withdrawal from above and below.
  • 5 shows the mode of operation with web take-off from above and FIG. 6 with web take-off from below
  • 7-10 roughly schematically the section through a splice element with a clamping element for the end of the running web, with which the connection can be made when changing the unwinding direction from one roll to the next.
  • Fig. 11 in a partially sectioned oblique view a further embodiment of a splice element, for use in changing directions of rotation of the supply rolls.
  • FIGS. 1 to 3 serves to connect the end of a running web to the beginning of the web of a new parent roll, the rolls being suspended in such a way that the web is pulled off from above. The rolls therefore rotate clockwise when unwinding when the web is pulled off to the bottom right - as shown in FIGS. 1-3.
  • the device shown is used for unwinding paper rolls that are wound on continuous metal axes, which are referred to as reels, and can have a weight of over 50 t with a web width of 8 m and more.
  • 1 shows a side view after the start of the unwinding process.
  • the still full mother roll 1 is suspended with its reel 2 in a unwinding frame with two side stands 3.
  • An existing lateral brake generator which can brake the winding roll 1 in generator operation as well as drive it in motor operation, is not shown in the simplified drawings.
  • the paper web 4 is pulled off from above and guided slightly deflected by a guide roller 5 to a subsequent roll cutting and winding machine, where it is divided lengthways into individual webs and wound up into smaller winding rolls.
  • the device according to the invention for connecting the end of a running web to the beginning of the web of a new parent roll contains as essential features a holding element for the running web, a separating element arranged behind it in the direction of the web end, and a pressing element which contacts the held web part of the running web brings outermost position of the new mother roll and is therefore arranged in front of it in the area of the holding element or in the direction of the web end.
  • these three elements are advantageously realized as a structural unit in a splice element 6, which is described in more detail below:
  • a pipe 7 extending over the entire working width with elastic, e.g. rubberized surface 8 is rotatably supported in the free end of two side levers 9 by means of a drive, not shown, with adjustable torque.
  • the levers 9 are pivoted at their other end to bearing blocks 10 fastened to the floor about the pivot axis 11, so that the tube 7 from the position shown in FIG. 1 outside the path of the paper web 4 in the direction of the arrow 12 up to the vicinity the storage of the drum 2 can be pivoted by means of a swivel drive 13.
  • the tube 7 has on its outer surface an axially extending groove 14 across the working width, in the as a separating element a cutting knife 15, which is provided with a cutting drive and can be moved radially out of the groove, is arranged.
  • a traversing knife that is to say which can be moved across the working width, can be arranged on the tube 7.
  • a suction zone 16 which also extends over the working width, adjoins the groove 14 in the counterclockwise direction and is formed by a plurality of suction openings.
  • a suction fan (not shown) is used to generate a vacuum inside the tube 7.
  • the unwinding process is braked.
  • the remaining size is selected so that there are at least three to four layers of paper on the reel 2 when it is at a standstill.
  • the splice device 6 is pivoted from the outside in the direction of the arrow 12 against the taut paper web 4, so that when the standstill is stopped the suction zone 16 lies flat against the web 4 and the suction openings are sufficiently covered.
  • the groove 14 is also covered by the web 4 with the cutting knife 15.
  • the tube 7 lies against the remaining roll 17 or stops at a short distance therefrom.
  • an adhesive seam 18 was attached before hanging, for example a double-sided adhesive strip or a trace of glue.
  • the new roll 1 was suspended or rotated so that the adhesive seam 18 is opposite the direction of rotation of the roll 1 at a distance from the pressure point 19 of the tube 7, which is shorter than the web remnant held on the tube 7 behind the pressure point 19 .
  • the tube 7 is then pivoted against the full roll 1 and is under pressure (Fig. 3).
  • Fig. 3 By switching on the preferred devices for the web 4, for example the subsequent winding machine, both the tube 7 and the roller 1 are caused to rotate due to the contact with friction.
  • the adhesive seam 18 moves through the pressurized nip at the pressure point 19, and a durable adhesive connection is produced between the rest of the web 4 and the beginning of the roll 1.
  • the acceleration of the roller 1 from standstill can be assisted by the drum drive or triggered alone, especially with very high roller weights. It is advantageous if the roll 1 - as described above - is at least partially moved by the running web 4, since this keeps it taut at all times.
  • a controller is expediently provided which, when the permissible web tension of the running web 4 is exceeded, switches on the drum drive for support.
  • the splice element 6 is pivoted back further by the track 4 until the waiting position shown in FIG. 1 is reached.
  • the swiveling away from the full roll 1 also takes place at the beginning with the web 4 now connected in order to keep it taut at all times.
  • the newly inserted roller 1 can then be accelerated to working speed.
  • FIG. 4 shows an embodiment of the invention in very confined spaces and with a guide roller 5 located approximately at the level of the web 4 that has been pulled off. Bru 4 is therefore subtracted from the full roll 1 in a direction inclined only slightly downwards.
  • the swivel levers 9 are not articulated in a frame 3.1, but in a height dependent on the required length of the levers 9. Except for this difference, the device according to FIG. 4 corresponds to the device shown in FIGS. 1 to 3, since there the web 4 is also pulled off from above, the roll 1 thus also rotates clockwise during unwinding.
  • FIG. 5 and 6 an embodiment of the invention is shown, which can advantageously be used both for unwinding with web withdrawal from above (FIG. 5) and with web withdrawal from below (FIG. 6).
  • this embodiment is particularly suitable for installation in confined spaces.
  • the structure of the embodiment according to FIGS. 5 and 6 corresponds to the device according to FIGS. 1 to 3 described above, with the splice element 6 being arranged in the pivoting levers 9 as an additional feature in the longitudinal direction thereof.
  • the length of the swivel lever 9 and the adjustment path of the splice element 6 is chosen so that when the swivel position is outside the area of a full roll 1, the splice element 6 both up to above the path 4.1 when the path is pulled off from above (position A in FIG. 5) and can also be driven up to below the course 4.2 when the web is withdrawn from below (position A 'in FIG. 6).
  • the tube 7 is supported at both ends in a carriage which can be moved by means of a motor in guides extending over the length of the swivel levers 9.
  • a motor with a drive pinion is attached to each slide, each meshing with racks attached to the pivot levers 9.
  • the tube 7 has a suction zone 16.1, 16.2 on both sides of the groove 14.
  • the splice element 6 After the start of the unwinding process, the splice element 6 is in the rest position A above the course of the web 4.1. As the diameter of the parent roll 1 decreases, the path of the web moves downward until the unwinding process is braked at a predetermined diameter of the remaining roll 17. Then the splice element 6 is moved downward in the pivoting levers 9 until the tube 7 dips into the web 4.1 (dashed line in FIG. 5, item B). The tube 7 is rotated into the cutting position in which both the groove 14 and the suction zone 16.1 are covered by the web 4.1. The suction blower is then put into operation to hold the web 4.1 and the web 4.1 is cut with the knife 15.
  • the splice element 6 is moved upwards in the swivel levers 9.
  • the tube 7 is rotated clockwise in order to keep the web 4.1 taut.
  • the splice element 6 thus reaches the position C, the swivel arms 9 possibly being pivoted further in the direction of the guide roller 5 in order to make room for a new full roller 1.
  • the tube 7 is pivoted against its outer surface, and the adhesive connection between the end of the running web 4.1 and the start of the new web is produced in the manner described above.
  • the splice element 6 is moved into the rest position A and thus back into the starting position.
  • Fig. 6 the operation of the device is roughly shown schematically with a supply roll 1 with web take-off from below.
  • the splice element 6 is in the rest position below the web 4.2 (position A '). This position corresponds to position B in FIG. 5.
  • position B the position of the web moves upward with a decreasing diameter.
  • the unwinding is stopped and the tube 7 is moved against the web 4.2 from below.
  • the tube 7 is moved to the position B ', in which the web 4.2, the suction zone 16.2 and the groove 14 with the knife 15 are flat covers.
  • the web 4.2 is cut and held in the manner described.
  • the remaining roll 17 is then removed and a new roll 1 with pre-positioned adhesive seam 18 is hung in.
  • the position of the adhesive seam 18 is in the region below the pressure point 19.
  • the splice element 6 is then moved against the circumference of the roll 1 by moving it downward in the pivoting levers 9 and additionally against the roll 1 can be pivoted.
  • the tube 7 is rotated counterclockwise in order to keep the web 4.2 taut and to provide a web remainder of a certain length below the pressure point 19 on the roll 1 (position C ').
  • the adhesive connection is established by rotating the full roll 1 counterclockwise and the tube 7 clockwise. As a result, the adhesive seam 18 is moved through the nip at the pressure point 19 and the connection between the two webs is thus established.
  • the additional swivel option enables operation with full rollers that have large differences in diameter. Furthermore, due to the combined linear and pivoting movement, the pressure point 19 can be fixed in a constant manner with a changing diameter of the full roll 1. This enables the adhesive seam 18 to be provided outside the stand 3 within a constant area. In addition, the splice element 6 can be moved completely out of its working area (position D in FIG. 5) in order to make the area between the running roller 1 and the guide roller 5 accessible for other purposes.

  • the wire rope can be swiveled to both groove inner walls by means of a swivel drive and is thus able to clamp web ends coming from both directions.
  • the clamping area in the groove 14 can be designed such that the wire rope 20.2 comes to rest on an arcuate line.
  • FIG. 10 corresponds to position C in FIG. 5.
  • the web end is correspondingly transferred from the suction zone 16.1 to the suction zone 16.2, with the rotation in the other direction - also in the paper travel direction - and the clamping element 20 the beginning of the web on the opposite inner wall of the Groove 14 clamped.
  • the suction pipe 7 has a groove 14 extending over its entire length with flanks 14.1, 14.2 which are beveled outwards in the region of the surface of the pipe 7, to which suction zones 16.1, 16.2 are connected on both sides.
  • the groove 14 serves as a guide for a cross-sectioned slide 21 which can be moved over the working width by means of a drive. Following the beveled flanks 14.1, 14.2, parallel sides 14.3 of the groove 14 first follow, and then widen again.
