Definitions

  • the invention relates to a method for splicing webs, in particular paper webs for the production of corrugated cardboard with the features of the preamble of patent claim 1. Furthermore, the invention relates to a device for splicing webs according to the preamble of patent claim 10.
  • a method for splicing paper webs for the production of corrugated cardboard is known from DE-OS 2 129 903.
  • the beginning of a prepared second web to be pulled off a roll is connected to a first web running off a roll, for example when it comes to an end.
  • the first track is brought to a standstill at the junction.
  • the first web is cut off.
  • the web which continued to run out of the device for splicing the webs was taken from a storage device which contains one or more web loops.
  • the shut down web part and thus also the second prepared web roll is accelerated by the web train being exercised.
  • the disadvantage here is that the role of the second prepared web, which has a relatively large mass, must be accelerated from the speed V0 to the final speed V. In the case of high-performance corrugated cardboard plants, the splicing and thus the run-up of the second web to the high top speed should also take place relatively quickly.
  • the invention has for its object to provide a method and an apparatus which enables the splicing of webs to be carried out in a very short time in a simple manner even at high speed.
  • the time for splicing can also be reduced at high speed. Additional and separate drives for the second roll can be spared if the web train for the roll of the second web is formed by forming a web loop between the start of this web and the roll. Such a drive for the acceleration of the second web roll is easy to manufacture. According to embodiments of the invention, this web loop can be used for storage purposes and / or for web tension control.
  • the device for carrying out such a method provides that between the roll of the second web and the fixed start of this web there is at least one storage roller which is displaceably guided transversely to a web section and whose displacement drive can be controlled in terms of time and / or force.
  • the invention is described below in connection with a paper web for the production of corrugated cardboard.
  • the device for splicing two paper webs comprises a splicing device 1 and a roll-off frame 2.
  • the roll-off frame 2 has double pairs of arms 3 and 4 for rotatably accommodating a running paper roll 5 and a paper roll 6 prepared for the later process.
  • the paper rolls 5, 6 can be braked by a conventional time-controllable and adjustable braking device.
  • the stand 8 of the unwind stand 2 resting on the floor 7 continues upwards into a stand part 9 which carries horizontal cheeks 10 of the splicing device 1. Between the cheeks 10, of which the front is to be regarded as removed, there is a deflecting roller 11 and a deflecting roller 12 for the running web 13 on the right end part. A pressing and deflecting roller 14 is wrapped by the running web 13. From this pressure and deflection roller 14, the web 13 then continues to a horizontally displaceably guided, against a preset force movable storage roller 15, the one web between the fully extended end position to the dash-dot position indicated loop 16 forms. From the storage roller 15, the web 13 runs horizontally to a discharge roller 17 at the left end of the cheeks 10. From there, the web 13 continues to a device, not shown, of the entire corrugated cardboard system, which pulls the web 13 with a corresponding tensile force.
  • the pressure and deflection roller 14 is rotatably mounted on a rocker 20 which can be pivoted back and forth.
  • the rocker 20 can be pivoted about the fixed central axis 21.
  • a further pressure and deflection roller 22 is rotatably arranged.
  • the pressure and deflection rollers 14 and 22 are mutually displaceable.
  • a holding roller 25 is rotatably and displaceably arranged in a guide track 26 below the pressure roller and deflection roller 14.
  • the holding roller 25 holds in the working position A below the pressure and deflection roller 14 the beginning 27 of the prepared web 28, which is pulled off the web roll 6 on the pair of arms 4.
  • the holding roller 25 can be provided with a pressure-sensitive adhesive layer 29.
  • the holding roller 25 In the initial position B, the holding roller 25 assumes the position shown in broken lines in FIG. 1 at the left end of the cheeks 10. The holding roller passes into this starting position B via the downwardly curved guide track 26. In the starting position B, the holding roller 25 is fixed in its rotational position.
  • the end 30 of the prepared paper web 28 is first passed over the deflection roller 31 and a storage roller 32 and then placed over the holding roller 25.
  • a bar-shaped knife carrier 35 is arranged in the starting position B next to the holding roller 25. This knife holder 35 can also be moved into this starting position B via the guideway 26. In this starting position B, the knife carrier 35 can be pressed against the holding roller 25 and thus locked.
  • the contact surface 36 on one side 37 of the knife carrier 35 is curved in accordance with the surface of the holding roller 25.
  • the contact surface 36 can have a corresponding elastic covering.
  • the web end 30 is covered with a bonding layer, preferably a double-sided adhesive tape 40, preferably 5 cm wide, or another adhesive, e.g. Hot melt, sprayed on or as a caterpillar application. Behind the adhesive tape 40, the end 30 is trimmed manually or automatically with the aid of a knife with the aid of a cutting bar (not shown).
  • a bonding layer preferably a double-sided adhesive tape 40, preferably 5 cm wide, or another adhesive, e.g. Hot melt, sprayed on or as a caterpillar application.
  • the end 30 is trimmed manually or automatically with the aid of a knife with the aid of a cutting bar (not shown).
  • the holding roller 25 with the latched knife carrier 35 with the web 28 is now moved into the working position A according to FIG. 1.
  • the web 28 is guided around the deflection roller 33, which is preferably perpendicular to the deflection roller 31.
  • the knife carrier 35 is brought into a horizontal position.
  • the holding roller 25 is held in such a position that the web end 30 encloses the roller 25 in a semicircular shape.
  • the knife carrier 35 in turn has on the side 38 opposite the side 37 a curved contact surface 43, correspondingly designed as the contact surface 36. It also has a flat, preferably horizontal upper side 44 over which the running web 13 runs.
  • the knife carrier 35 has two serrated knives 45, 46 which extend over the entire web width (FIG. 3). These are alternately from the retracted position to the Active position can be extended, for which purpose a knife drive device, not shown, is used.
  • the knives 45, 46 run obliquely to the web 13.
  • the extended knife extends into the free gusset space 47 between the rollers 14 and 25 pressed against one another.
  • the running web 13 can be cut off at the slightest distance from the linear contact of the rollers 14, 25 . This distance corresponds approximately to the width of the connecting layer, for example the adhesive tape 40.
  • the knife carrier 35 can also be transferred into a right-hand starting position B 'via the guideway 26 which continues to the right (FIG. 1). In this he works with a second holding roller 39 to clamp the beginning 30 'of a prepared paper roll 6 in the right pair of arms 3, as described (Fig. 2).
  • height-adjustable pressure bars 50, 51 are arranged. These have a friction lining 52 on their underside.
  • the pressure bars 50, 51 are pressed alternately against the top 44 of the knife carrier 35 and thereby hold the running paper web 13 running between the bottom of the pressure bar 50, 51 and the top 44 of the knife bar 35.
  • the storage roller 32 is guided horizontally by a sliding guide 56. If the web end 30 is transferred to the working position A by the pressure and deflection roller 25 together with knife carriers 35, the prepared web 28 runs over the deflection rollers 31, 33.
  • a displacement drive for the storage roller 32 can be switched on as a function of time or in a time-controlled manner.
  • the storage roller 32 is moved vertically against the web piece between the deflection rollers 31 and 33 and takes it along with the formation of a loop 57. Since the start 30 of the web 28 is clamped in the working position A, a train is effected on the web 28 and thus a rotation on the roller 6 in the downward direction (counterclockwise) to form the loop 57.
  • the speed of movement of the storage roller 32 can be constant or increasingly controlled. It is preferably designed such that when the storage roller 32 reaches its right-hand end position shown in dash-dotted lines in FIG. 1, the speed of the web roll 6 and thus the speed of the web 28 in the region of the loop 57 approximately V the outlet speed V from the splicing device 1 the discharge roller 17.
  • the end 30 Before or during reaching the end position of the storage roller 32, the end 30 can be connected to the running web 13. For this purpose, the pressure beam 50 is pressed against the knife carrier 35. As a result, the web 13 is stopped at this point.
  • the end 30 of the web 28 is now connected to the web 13 by pressing the roller 14 against the holding roller 25, for which purpose the rocker 20 is pivoted clockwise about the pivot axis 21.
  • the web 13 is attached to the tape 40 pressed at the beginning 30 of the web 28 and the adhesive bond completed.
  • the pressure and deflection roller 22 is displaced in the direction of the pressure and deflection roller 14 and pressed against it.
  • the serrated knife 45 cuts off the web 13.
  • the stop of the web 13 is canceled by the pressure bar 50 and cutter bar 44.
  • the pressure bar 50 starts up again.
  • the pressure of the knife carrier 35 on the holding roller 25 is also released; the knife carrier 35 extends to the right.
  • the web tension further exerted by a machine of the corrugated cardboard plant following the splicing device 1 now causes the web 28 connected to the web 13 to be pulled off the roll 6.
  • the adhesive bond is pressed by the pressure roller 22.
  • the storage roller 32 which is in the right position, can now move back to the starting position at the left end of the cheek 10 with a predetermined, constant or variable force at a constant or variable speed.
  • the loop 57 acts like an additional storage loop.
  • the running paper roll 5 is on the left arm pair 4
  • the prepared web 28 of the paper roll 6 on the arm pair 3 is assigned a further storage roller 55.
  • This storage roller 55 is displaceable on the sliding guide 56 for the storage roller 32.
  • arrangement and action of this storage roller 55 corresponds to the storage roller 32.
  • the storage roller 55 acts after the end 30 'by means of the pressure and deflection roller 39 and the cutter bar 35 has been transferred by moving into the working position A according to FIG. 2 against the vertical Track section between the deflection rollers 11 and 12 and further forms a loop 57 '.
  • the storage roller 55 reaches the left end position shown in broken lines in FIG. 2. Otherwise, the arrangement and movement of this storage roller 55 coincides with that of the storage roller 32.
  • a plurality of storage rollers 55 may be present to form a plurality of acceleration and storage loops 57 '.
  • the loops 57 and 57 'as well as the storage loop 15 fulfill the storage effect.
  • the storage rollers 15, 32 and 55 can be used for web tension control.
  • the storage roller 15 is then not firmly latched in an end position, but it can be moved horizontally to the left or right by a predetermined distance in a desired position (middle position). It counteracts the web tension exerted by a subsequent machine with a certain target force.
  • a sensor e.g. a potentiometer, detects the position of the roller 15 and outputs a signal to a controller, which compares this signal with a target value corresponding to the target position of the roller 15. As a result, the braking torque on the running roller 5 is regulated accordingly (position control).
  • the analog use of one of the two storage rollers 32 or 55 for web tension control is also possible.
  • the respective effective storage roller 32 or 55 moves into a desired position, forming a shorter loop.
  • the jewei works around this target position lige storage roller then as a so-called dancer roller, as described. After the roll change, the other storage roller then acts as a dancer roller.
