Definitions

  • the present invention relates to an apparatus for wrapping a wrapping material, which is arranged to be run around a wrapping track forming a guide for the apparatus in such a way that the apparatus is arranged to be travelled along the wrapping track and which wrapping track is arranged to be run through a centre hole of a piece to be wrapped, and which apparatus includes
  • the invention also relates to a method for wrapping a wrapping material, and a wrapping device.
  • Several solutions are known for wrapping cylindrical pieces with a centre hole.
  • the wrapping-material reel is taken through the centre hole of the piece to be wrapped by utilizing a wrapping shuttle travelling along an oval wrapping track.
  • the piece to be wrapped is rotated around its axis at the same as the wrapping shuttle moves along the wrapping track through and around the piece to be wrapped.
  • the wrapping material forms a continuous protective jacket on all the surfaces of the piece.
  • the wrapping material should be given sufficient tension or stretching, so that the wrapping material will press tightly onto the surface of the piece to be wrapped.
  • during wrapping there must be no slipping between the edges of the piece to be wrapped and the wrapping material.
  • the pieces to be wrapped can be, for example, coiled steel, aluminium, or a similar sheet material, in which the edges of the piece are sharp. Slipping of the wrapping material at the edges of the piece easily causes the wrapping material to break and thus the wrapping to be interrupted.
  • the application uses an oval-shaped wrapping track, which runs through the centre hole of the piece to be wrapped and along which the wrapping shuttle moves.
  • the distance of the wrapping shuttle from the surface and edges of the piece to be wrapped varies during wrapping. Particularly when the wrapping shuttle goes into the centre hole of the piece to be wrapped, or comes out from it, the said change in distance is considerable.
  • the invention is intended to create an apparatus and method for wrapping a wrapping material, which permits variation in the properties of the wrapping material, and which effectively implements the re-reeling of the wrapping material during wrapping.
  • the characterizing features of the apparatuses according to the invention are stated in Claims 1 and 6, and those of the method in Claim 7.
  • the invention also relates to a wrapping device the characteristic features of which are stated in Claim 8.
  • the tension of the wrapping material is arranged to be detected from the discharge arrangement arranged to affect to the wrapping-material source.
  • the mechanical implementation of the apparatus is simplified.
  • the invention also permits variation in the properties of the wrapping material.
  • owing to the invention is achieved effective re-reeling of the wrapping material. Thanks to the re-reeling, changes taking place during wrapping in the distance between the apparatus and the piece to be wrapped can be taken into account.
  • the tension of the wrapping material then remains as desired in each position of the apparatus relative to the piece to be wrapped.
  • the invention can be implemented, for example, as internal feedback.
  • an electric motor solution and particularly the feedback of the motor's control to the control unit of the motor relative to the force or moment caused by the motor to the wrapping-material source.
  • One first exemplary constructional solution is to arrange the motor to act on the wrapping-material source through a support-element arrangement.
  • a second exemplary constructional solution is to arrange the motor to act on the surface of the wrapping-material source through a pressure-roller arrangement.
  • the implementation of the invention requires no external sensoring at all.
  • the invention can also be implemented by means of external feedback.
  • One exemplary way of implementing this is by sensoring fitted to a support-element arrangement of the wrapping-material source.
  • the wrapping material can be led to the piece to be wrapped through a guide arrangement, in which principally one change of direction is created for the wrapping material.
  • a guide arrangement in which principally one change of direction is created for the wrapping material.
  • Figure 1 shows an example as a rough schematic diagram of the application environment of the apparatus 10 according to the invention, with a wrapping device 31.
  • the figure shows a top view of a wrapping device 31 used for wrapping cylindrical pieces 19 with a centre hole and the apparatus 10 arranged to move in it, in different locations E1 - E5, and a cross-section of the piece 19 to be wrapped.
  • the wrapping device 31 can include, as its basic components, the rotation apparatus (not shown) under the piece 19 required to rotate the piece 19 to be wrapped around its axis, the wrapping track 23, and the apparatus 10.
  • the wrapping track 23 is oval in shape and can be arranged to run through the centre hole 24 of the piece 19 to be wrapped.
  • the wrapping track 23 can be cut and turned or lifted, so that it can be taken to run through the centre hole 24 of the piece 19 and, on the other hand, also removed from there.
  • the wrapping track 23 forms a path of motion for the apparatus 10, a guide, in which the elements arranged for it in the apparatus 10 can be arranged, in such a way that the apparatus 10 travels along the wrapping track 23 in a closed loop.
  • the apparatus 10 has reference numbering for a support-element arrangement 12 for the wrapping-material source 11 and a wrapping-material source 11 fitted to it. From the wrapping-material source 11 the wrapping material 16 is arranged to be led, through a guide arrangement 28 belonging to the apparatus 10, to the piece 19 to be wrapped.
  • the apparatus 10 is in two parts. The parts are pivoted to each other in such a way that they can turn relative to each other, for example, in the sharp end curves of the wrapping track 23 and thus can retain the apparatus's 10 current-collector elements' 25 continuous unbroken contact with the counter-elements of the wrapping track 23.
  • Figure 1 also shows schematically the change in length of the wrapping material 16 between the piece 19 to be wrapped and the apparatus 10.
  • the length of the wrapping material 16 varies as the distance between the edges A, B, C, and D of the piece 19 to be wrapped and the point E1 - E5 of the path of motion of the apparatus 10.
  • the apparatus 10 progresses along the wrapping track 23 in the direction E1 - E5.
  • the length of the wrapping material 16 between the apparatus 10 and the piece 19 diminished especially quickly between E2 - E3.
  • the need for re-reeling of the wrapping material 16 is then greatest, in order to be able to preserve a suitable tension of the wrapping material 16 in terms of achieving a successful wrapping result.
  • Figure 2 shows a bottom view of a first example of the apparatus 10 for wrapping a wrapping material 16 and Figure 3 correspondingly a side view.
  • the basic components of the apparatus 10 include an assembly 14, a discharge arrangement 30 fitted at least partly to the assembly 14 for the wrapping-material source 11, and measuring means 17 for detecting the tension of the wrapping material 16.
  • the assembly 14 includes, for example, a body of the apparatus 10 assembled from one or more parts and, in addition, various equipment fitted to it for achieving the functions of the apparatus 10, which can vary even widely within the scope of the basic idea of the invention.
  • a discharge arrangement 30 for the wrapping-material source 11 is also fitted to the assembly 14.
  • the wrapping material 16 is arranged to be discharged from the wrapping-material source 11 by means of the discharge arrangement 30.
  • the discharge arrangement 30 can include a support-element arrangement 12 fitted to the apparatus 10 for the wrapping-material source 11, and drive means 38 ( Figure 3 ).
  • the wrapping material 16 is arranged to be discharged to wrapping from the support-element arrangement 12.
  • the support-element arrangement 12 can be formed of, for example, a rotatably arranged shaft arranged for the wrapping-material source 11.
  • the wrapping-material source 11, from which the wrapping material 16 is arranged to be discharged can be, for example, a reel equipped with a centre hole. The reel can be fitted to the shaft in such a way that it rotates along with the shaft.
  • the drive means 38 belonging to the discharge arrangement 30 are arranged to act on the wrapping-material source 11, in order to maintain the tension of the wrapping material 16 arranged to be discharged from it.
  • the drive means 38 can include, for example, an electric motor or similar operating device 13.
  • the operating device 13 is arranged to act on the wrapping-material source 11 through the support-element arrangement 12.
  • the electric motor is connected to the support-element arrangement 12 to maintain the tension of the wrapping material 16 being discharged from the wrapping-material source 11 and to re-reel the wrapping material 16.
  • the operating device 13 can be connected directly or indirectly to the support-element arrangement 12. In a direct connection, the motor can be attached directly to the shaft (not shown).
  • the power of the motor to the shaft can be transmitted, for example, by means of a cogwheel, belt, or chain transmission.
  • transmission can be direct primary transmission from the motor, or also secondary transmission.
  • transmission is implemented by means of a cogwheel 26 fitted to the shaft, a cogwheel 32 fitted to the motor, and a chain 21 arranged between them.
  • the drive means 38 belonging to the apparatus 10 and more particularly to the discharge arrangement 30 can also include a control unit 20 for the operating device 13.
  • the control unit 20 too is fitted to the apparatus 10, but equally it can also be separate from the apparatus 10, for example, in a control cabinet (not shown).
  • the control unit 20 By means of the control unit 20 the movement of the motor is controlled by feeding it voltage (or current) of a suitable magnitude.
  • the apparatus 10 also includes measuring means 17 for detecting the tension of the wrapping material 16.
  • Feedback 18 from the measuring means 17 is arranged to the drive means 38 and in this case particularly to the movement controller of the operating device 13, concerning the tension of the wrapping material 16 or a comparable variable.
  • the feedback 18 permits the control of the operating device 13 in such a way that the tension of the wrapping material 16 discharging from the reel will remain as desired and slack will not arise.
  • by means of the feedback 18 it is also possible to compensate for the change during wrapping in the distance between the path of motion of the apparatus 10 and the edges A - D of the piece 19 to be wrapped.
  • the tension of the wrapping material 16 being discharged from the wrapping-material source 11 is arranged to be detected from the discharge arrangement 30. This substantially simplifies the construction of the apparatus 10, because in this way the complicated measuring arrangements relating to a set of control rolls of the wrapping material 16, known from the prior art, are avoided.
  • the feedback 18 can be internal.
  • the internal feedback 18 can be implemented, for example, by means of a control unit 20 of the operating device 13 belonging to the discharge arrangement 30 of the apparatus 10.
  • the operating device 13 and its control unit 20 by means of which the tension of the wrapping material 16 to be discharged from the wrapping-material source 11 is controlled, can be arranged itself to also act as the measuring means 17 of the tension of the wrapping material 16.
  • the tension of the wrapping material 16 can be detected, for example, from the actual value of the current of the operating device 13, or a corresponding variable.
  • this function is depicted by the block 17 marked in the control unit 20, in which the signal proportional to the actual value of the current can be analysed and a possible change to the control of the operating device 13 can be made on its basis.
  • control can be by the torque, which the servomotor develops.
  • the control of the servomotor can be set to follow a torque value given to it. The response to this is produced by the torque arising in the shaft of the reel of the wrapping material 16. This torque is caused by the rope force of the wrapping material 16.
  • the current produces a torque, so that this can be controlled without external feedback by measuring the actual value of the current of the motor.
  • Adjustment of the torque is based on adjustment of the current of the servomotor, which creates the torque. Measurement of the current and feedback are implemented, for example, in a servo-amplifier.
  • the implementation of this embodiment is extremely simple. The tension measurement can be performed without surplus mechanical components or external sensoring, purely by a software component 17 in the motion-control unit. In addition, this is a quick way to adjust.
  • Figure 4 shows a second embodiment for implementing feedback 18 from the discharge arrangement 30.
  • the feedback 18 can also be external.
  • External feedback 18 can be implemented, for example, in such a way that the measuring means 17 include sensoring 27 fitted for this purpose to the discharge arrangement 30 for measuring, for example, torque or force.
  • the sensoring 27 can be, for example, in connection with the support-element arrangement 12. This embodiment too simplifies the implementation of the set of deflector rolls, because measurement of the variable proportional to the tension of the wrapping material 16 is no longer performed there.
  • the set of deflector rolls, more generally the guide arrangement 28 for the wrapping material 16 is simplified substantially.
  • the wrapping material 16 is arranged to be led to the piece 19 to be wrapped through a guide arrangement 28, in which principally one change in direction is arranged to be achieved for the wrapping material 16.
  • the guide arrangement 28 can be formed of a single deflector roll 29.
  • the deflector roll 29 arranged in the assembly 14, through which the wrapping material 16 is led to the piece 19 to be wrapped, can be freely rotating or nonrotating.
  • the tension of the wrapping material 16 can no longer substantially change between the wrapping-material reel and the piece 19 to be wrapped, as is the case in solutions according to the prior art based on several deflector rolls, for example from the affect of the rope force.
  • the tension in the wrapping material 16 is directly dependent on the torque acting on the shaft of the wrapping-material reel.
  • bearing friction is also minimized.
  • the response of the rope force to the shaft of the servo does not greatly weaken, because the wrapping material 16 runs through only a single deflector roll 28.
  • the force creating tension in the wrapping material 16 can also be transmitted directly to the surface 34 of the wrapping-material source 11.
  • Figure 5 shows an example of one possible arrangement relating to this.
  • the operating device 33 is arranged to act on the surface 34 of the wrapping-material source 11 through a pressure-roll arrangement 22.
  • the pressure-roll arrangement 22 includes a pressure roll, through which a braking force is transmitted to the surface 34 of the wrapping-material reel.
  • the operating device 33 affects the pressure roll 37.
  • the pressure roll 37 is now arranged at the end of a lever arm 35, which is rotatably pivoted to the assembly 14 at the opposite end.
  • the lever 35 is affected by, for example, a spring 36, which presses it against the surface 34 of the wrapping-material reel.
  • the wrapping-material source 11 is arranged to either rotate freely relative to the support-element arrangement 12, or alternatively non-rotatably to the support-element arrangement 12, when it is able in turn to rotate freely on its bearings.
  • the arrangement 22 based on a pressure roll can also be such, in which the movement of the pressure roll 37 is linear, i.e. straight towards the wrapping-material reel (in the direction of its radius).
  • the lever-arm or linear-motion arrangement may also be arranged to act on the support-element arrangement 12 of the wrapping-material reel, in which case the embodiment corresponds in principle to that shown in Figures 2 - 4 (the chain drive has been replaced by a roll drive).
  • the pressure roll 37 can be stationary against the shaft.
  • the drive of the pressure roll 37 by the operating device 33 can again be arranged either directly or through a transmission.
  • At least part of the drive means 38 and the wrapping-material source 11 can be fitted to the apparatus 10 detachably.
  • the wrapping-material source 11 and also the motor can be changed easily and quickly.
  • the control unit 20 of the drive means 38 From the diameter of the wrapping-material source 11 it is possible to arrange, for example, external feedback to the control unit 20 of the drive means 38.
  • External feedback can be achieved, for example, by means of a location sensor, which is in contact with the surface of the wrapping-material source 11.
  • Other examples of sensoring are ultrasound, a laser, or a potentiometer.
  • the change in the radius of the reel of wrapping material 16, i.e. the decrease in wrapping material 16 causes a reduction in the force arm, which is compensated for by correspondingly correcting the torque instruction.
  • the control unit 20 of the drive means 38 can be located separately from the apparatus 10.
  • a connection is implemented between the servo-controller and the servomotor fitted to the apparatus 10, in such a way that the controller can be located permanently outside the wrapping carriage, for example in a control cabinet.
  • the invention relates equally to a system for wrapping a wrapping material 16, in which an apparatus 10, which in its basic principles is like that described above, is without a control unit 20 fitted to it, which is now therefore separate from the apparatus 10.
  • the tension of the wrapping material 16 is arranged to be detected by means of the control unit 20.
  • the invention also relates to a method for wrapping a wrapping material.
  • wrapping material 16 is discharged from a wrapping-material source 11 by means of a discharge arrangement 30, the tension of the wrapping material 16 is determined while discharging it from the wrapping-material source 11, and the tension of the wrapping material 16 being discharged from the wrapping-material source 11 is maintained on the basis of the determination.
  • the tension of the wrapping material 16 is determined from the discharge arrangement 30, for example, according to any of the embodiments described above.
