Definitions

  • the present invention relates to an apparatus for binding a load with tape.
  • the apparatus is of the type which applies a stretchable adhesive tape to a rotating load to bind the load in a helical pattern.
  • the invention also relates to a detection system which can automatically determine one or more parameters of the load.
  • Palletising apparatus which apply tape to a load. See for example our previous international patent application WO/0230751.
  • tape is drawn from a roll of tape to a load which is rotated on a turntable.
  • the roll of tape, as well as the tape stretching mechanism is mounted on a carriage which moves up and down at the side of the load. As the tape is drawn off and the load is rotated, the tape will be applied in helical patterns on the load.
  • the stretching mechanism the roll of tape, the structure for supporting the roll and the carriage motor all mounted on the carriage, the carriage will have considerable weight and bulk. This slows down the speed at which the carriage can be moved and affects the ability of the carriage to stop and reverse direction. This has an effect on the binding speed because the speed of the carriage is generally the limiting factor in binding a load.
  • an apparatus for binding a load with tape including:
  • a load rotation device for rotating a load
  • a first tape guide movable upwards and downwards relative to the load to guide tape onto the load
  • a tape handling mechanism mounted to a substantially stationery body of the apparatus, the tape handling mechanism including a tape holder for holding a roll of tape;
  • a tape take-up device disposed between the tape handling mechanism and the first tape guide for passage of the tape therethrough, the take-up device adapted to provide passage for a substantially constant length of tape therethrough.
  • the first tape guide may be in the form of a roller or a fixed spindle (or a set or pair of rollers or spindles) past which the tape passes.
  • the first tape guide moves up and down beside the load and as such, may be provided on a carriage which is moveable on an upright mast which extends alongside the load.
  • the tape handling mechanism is provided on a stationery body of the apparatus which may be disposed adjacent the mast.
  • the tape handling mechanism may include the tape holder and the tape stretching mechanism.
  • a drive for movement of the first tape guide/carriage may be provided on the body.
  • the tape stretching mechanism may be disposed between the tape holder and the tape take-up device.
  • the tape take-up device may incorporate a second tape guide which is also moveable relative to the load but which is also moveable relative to the first tape guide to result in a substantially constant length of tape through the take-up device.
  • the tape handling mechanism may also include a third tape guide and preferably this third tape guide is fixed relative to the first and second tape guides.
  • the third tape guide may define the beginning of the tape take-up device.
  • the third tape guide is optional and the beginning of the take-up device could be defined by the point where the tape leaves the tape holder, this being substantially fixed.
  • the end of the tape stretching mechanism which is fixed could define the start of the take-up device.
  • Each of the second and third tape guides may define a roller or a fixed spindle over/around which the tape passes.
  • the second tape guide is also moveable to maintain a constant length of tape between the first and third tape guides.
  • the first and second tape guides may be mounted on respective carriages which travel up and down on parallel or substantially aligned linear paths. Accordingly, the carriages of the first and second tape guides may be moveably mounted on a common mast. It is preferred that the second tape guide is disposed above the third tape guide and the tape passes below the third tape guide, around the top of the second tape guide and below the first tape guide.
  • the second tape guide need only move upwards by half of the given amount to maintain the constant length of tape between the first tape guide and the third tape guide.
  • the second tape guide need only move half the speed of the first tape guide.
  • this arrangement could be reversed with the first tape guide disposed above the second tape guide.
  • the first and second tape guides may be driven by a common drive but at different speeds using respective belt drives which are driven from respective toothed wheels of different sizes with both wheels driven by a common drive shaft.
  • the carriages will be able to travel at significantly faster speeds than before, thereby speeding up the binding process.
  • the apparatus could be doubled in order to provide two tape holders with each tape holder having an associated first tape guide and an associated tape take-up device. In this way, the load can be wrapped with two tapes at once.
  • an apparatus for binding a load with tape including:
  • a load rotation device for rotating a load
  • a first tape dispensing apparatus for applying tape to the load drawn from a first roll of tape
  • a second tape dispensing apparatus to apply tape to the load drawn from a second roll of tape.
  • the first and second tape dispensing apparatus operate simultaneously to apply tape at the same time to the load.
  • the first and second tape dispensing apparatus may be limited to cooperate to apply tapes such that the net result is a predetermined pattern.
  • a controller may be provided to link the operation of the first and second tape dispensing apparatus.
  • the first and second tape dispensing apparatus may be mechanically linked via a toothed belt drive.
  • the first and second tape dispensing apparatus may be provided on opposite sides of the load. They may be diametrically opposed relative to the load rotation device.
  • a detection system to determine load parameters including:
  • one or more height detectors disposed to detect the height of the load
  • one or more load detecting sensors for detecting a predetermined portion of the load
  • the one or more load detecting sensors and the load are arranged for relative movement such that the one or more load detecting sensors are adapted to be triggered on the predetermined portion(s) of the load moving past the or each sensor, wherein the operation of the one or more height detectors is responsive to at least one of the one or more load detecting sensors to obtain a value corresponding to the height of the load at or near predetermined portion(s) of the load.
  • the two height detectors are disposed on the left and right as viewed from the front of the load. Accordingly, on the first detector detecting the leading edge of the load, the two height detectors will determine the height of the left front of the load and the right front of the load. Preferably, the height detectors are disposed above the load.
  • the same height detectors may be used when the trailing edge of the load is detected by the second detector. Accordingly, the two height detectors will detect the height of the left rear of the load and the right rear of the load.
  • the first and second detectors may be spaced either side of the height detector(s). Accordingly, the first detector will determine the leading edge slightly after it has passed under the height detector(s). Also, the second detector will determine the trailing edge before it passes the one or more height detectors. Preferably, the height detectors are such that they take multiple readings in quick succession. Appropriate software may be incorporated into the detection system to discard spurious readings and make an average of the remaining readings.
  • the detection system includes a conveyor to convey the load past the various detectors which are fixed.
  • the load may remain fixed and the sensors may be moveable.
  • the conveyor may convey the load onto a turntable to rotate the load so that it may be bound with tape as described above in accordance with the first and second aspects of the invention. Accordingly, any of the features described above in connection with the first and second aspects of the invention may be incorporated into the third aspect described above.
  • the detection system may incorporate a timer to determine the time taken for the load to trigger the first detector and then the second detector. Given the space that the detectors are apart and also knowing the speed of the conveyor, the software associated with the detection system can determine the length of the load from the leading edge to the trailing edge.
  • the load detectors may comprise retro-reflective photo eyes. These are photo eyes which produce a light beam which is reflected back from a reflector. The breaking of the beam triggered by the leading edge of the load causes a relay to change state, such that the leading edge of the load can be determined. Likewise, the reinstatement of the beam as the trailing edge passes the detector also causes the relay to change state.
  • the height detectors may comprise infrared laser measuring devices. Preferably, the devices are positioned on a frame above the load.
  • the various parameters determined by the load detection systems can be used in tape binding apparatus to create load binding patterns with greater certainty.

  • the load binding apparatus 10 will be arranged adjacent a load rotation device such as a turntable (not shown), on which the load will be supported.
  • a typical load is a palletised load 12 shown in Figure 10 comprising an array of cartons 14 on a pallet 16.
  • the load 12 may be moved by a conveyor 18 to the turntable.
  • An appropriate turntable is that described in either of our earlier Australian patent no. 615778 and earlier application Australian application no. 2001291519 and US Serial no 10/398675. The contents of these earlier applications are disclosed herein by reference.
  • the load binding apparatus 10 includes a body 20 comprising a base 22 and an upright mast 24 fixedly mounted to the base 22 by means of fasteners and the like.
  • a drive motor 26 is also mounted to the base 22, the purpose of which will be explained later.
  • a tape handling mechanism 28 is fixedly mounted on the mast 24 at a height approximately one third up the length of the mast 24.
  • the tape handling mechanism 28 includes a tape holder which holds a roll of tape 30.
  • the tape handling mechanism also includes a tape stretching mechanism 32.
  • the tape stretching mechanism 32 will stretch the tape in a manner known in the art. An appropriate tape stretching mechanism is described in our earlier patent applications, Australian application no 2001291519 and US Serial no 10/398675, the details of which are incorporated herein by reference.
  • the load binding apparatus 10 also includes a first carriage 34 which is moveable up and down the mast 24.
  • the first carriage 34 is shown in greater detail in Figures 5 through to 8. Referring to Figure 5, it can be seen that the first carriage 34 includes a pair of spaced rollers 36 which facilitate movement of the carriage up and down the mast 24.
  • a first tape guide 38 in the form of two spaced rollers 40 is provided on the first carriage 34. From the first tape guide 38, the tape 42 passes to the load for binding the load.
  • the two rollers 40 are mounted at the end of a rotatable bar 44.
  • the rotatable bar 44 may be mounted at the other end to a reorienting wheel 46.
  • the wheel 46 may be selectively driven to rotate by belt drive 48.
  • the bar 44 can be selectively moved between the orientation shown in Figure 5 to a second orientation shown in Figure 7.
  • Figure 7 depicts the tape 42 after passage through the rollers 40 with the adhesive side of the tape facing out of the page, then in Figure 7 the corresponding portion of the tape will have the adhesive side facing into the page.
  • the belt drive 48 is driven by a carriage motor 50 mounted on the first carriage 34.
  • a second carriage 52 is disposed above the first carriage 34.
  • the second carriage 52 includes a second tape guide 54 in the form of a roller, around which the tape passes.
  • a third tape guide 56 in the form of a roller is mounted to the mast 24.
  • the roll of tape 30 is loaded onto a tape holder forming part of the tape handling mechanism.
  • the axis of the roll will thus be relatively stationary relative to the stationary body 20 of the apparatus 10.
  • the tape drawn off the roll will first pass through the tape stretching mechanism 32, around the third tape guide 56, over the second tape guide 54 and through the first carriage 34 to the first tape guide 38 and then to the load. It can be seen that the tape passes from the roll 30 through the tape stretching mechanism 32, the third and second tape guides 56, 54 with the width of the tape normal to the page. Referring to Figure 5, on reaching the first carriage 34, the tape passes around a fourth tape guide 58 where it again changes direction through 90°.
  • the tape 42 twists through 90° so that the width of the tape is orientated with the plane of the page as shown. This twist is necessary so that a substantially flat face of the tape is applied to the load.
  • the tape will be applied at a slight angle to the vertical as can be understood from a study of Figure 6.
  • the first carriage 34 is moved up and down the mast 24 while the tape 42 is being drawn from the roll 30. Given that the roll of tape 30 is mounted on a stationary body, if the tape were to pass straight to first carriage 34 from the third tape guide 56, then the distance from the roll to the first carriage would vary as the first carriage 34 moves up and down the mast 24. This is unacceptable in practice.
  • the second carriage 52 forms a tape take-up device which ensures that the length of the tape from the third tape guide 56 to the first tape guide 38 is substantially constant. Accordingly, as the first carriage 34 moves up, the second carriage 52 will also move up. However, it would be appreciated that the tape is doubled over between the third tape guide 56 and the second carriage 54. Therefore, as the first carriage 34 moves up a certain distance, the second carriage 52 only needs to move up half this distance. Accordingly, the second carriage 52 need move at only half the speed of the first carriage 34.
  • Figure 2 illustrates another position of the first carriage 34 and a corresponding position of the second carriage 52.
  • Figures 3 and 4 illustrate the drive means for the first carriage 34 and the second carriage 52 respectively.
  • the first carriage 34 is driven by a drive belt 60 by motor 26.
  • the drive belt 60 passes around sprocket wheel 62 having an outer periphery of teeth 64.
  • the two ends of the drive belt 60 are connected to the first carriage 34.
  • the first carriage 34 may therefore be driven up and down, depending upon the direction of the motor 26.
  • a second drive belt 66 drives the second carriage 52.
  • the second drive belt 66 passes around an inner toothed wheel 68 of the sprocket wheel 62. However, since the inner toothed wheel 68 is smaller than the outer toothed wheel 64, the upper carriage 52 will be driven at a slower speed.
  • the outer end of the tape 42 is first applied to the load manually.
  • the first carriage may be programmed to stop at a height which is convenient for the user to grab the end of the tape from beyond the first tape guide 38 and apply it to the load.
  • this step may be automated (not shown).
  • the load rotation device i.e. the turntable then rotates the load.
  • the tape 42 will be drawn from the apparatus 10 and will wind around the load.
  • the carriage 34 moves up and down beside the load.
  • the load will be bound in a helical pattern.
  • the second carriage 52 will also move up and down to equalise the distance between the first tape guide 38 and the third tape guide 56.
  • the tape used to bind the load may be of the type described in US patent no.
  • the tape is stretchable and is provided with adhesive on one side.
  • the stretching of the tape reduces the degree of adhesiveness but the tape still retains a smaller level of adhesiveness.
  • the apparatus 10 may be programmable to change the orientation of the tape for a predetermined length of time or rotation of the load.
  • the load is bound with a helical pattern.
  • the orientation of the tape may be changed so as to present the adhesive side of the tape facing away from the load. This is achieved by rotating the first tape guide 38 as shown in conjunction with Figures 5 to 8. This orientation is maintained until the load rotates through approximately a full revolution. After this, the first tape guide 38 reverts to the orientation shown in Figure 5 to thereby again present the adhesive side towards the load.
  • This apparatus 70 includes the apparatus 10 of Figure 1 in doubled-up form. Thus there will be two masts 24 on each side of a central turntable 72. Each apparatus 10 operating simultaneously feeds tape to the central load 12.
  • the two parts 10 may be limited by a toothed belt drive to coordinate their operation.
  • Figures 10 to 12 illustrate a detection system 80 to detect parameters of the load 12 such as height and length. Such information can then be passed to the programmable controller of the binding apparatus 10, 70. This reduces the need for an operator to take and enter measurements of the load.
  • the detection system 80 includes a conveyor 18 to convey the load 12 through the detection system. Further, a gantry 82 is provided to provide a mounting for two height detectors 84, 86 above the load 12.
  • the detection system 80 also includes a first load detecting sensor and a second load detection sensor 90.
  • the load detecting sensors may comprise retro-reflective photo eyes which produce a light beam which is reflected back from a reflector on the other side of the conveyor 18. As the load 12 is conveyed along the conveyor 18, the leading edge 92 of the load 12 will break the beam from the first detector 88. Thus the detection system can detect the leading edge of the load 12. The detection of the leading edge will trigger the two height sensors 84, 86 to take readings of the height of the top of the load immediately underneath the sensors.
  • the height detectors 84, 86 may comprise infrared laser measuring devices. These height detectors may take multiple readings in quick succession.
  • the detection system 80 may incorporate appropriate software to discard spurious readings and make an average of the remaining readings. Accordingly, the height of the top right of the load and the top left of the load can be determined.
  • the trailing edge 94 of the load will be detected. This will trigger the height detectors 84, 86 to take readings of the height of the top of the load. Thus, the height of the rear right and the rear left of the load will be known. Additionally, the detection system 80 may incorporate a timer to determine the time taken for the load to pass past the first sensor 88. Given the speed of the conveyor 18, the software associated with the detection system 80 can determine the length of the load from the leading edge 92 to the trailing edge 94.
  • the detection system 80 thus provides more accurate information concerning the load parameters. This will avoid an operator needing to manually measure the parameters of the load.
  • the load binding apparatus 10, 70 can determine an appropriate binding pattern which will effectively bind the load. For example, if a load 12 has an incomplete top layer then the binding apparatus can bind the load with an appropriate pattern that may include loops which extend over the top of the load as described in conjunction with our previous patent applications US Serial no. 11/443559 and European application no. 02759917.

Abstract

L'invention concerne un ruban (42) qui est enroulé en spirale autour d'une charge en rotation (non représentée) pendant des mouvements de montée et de descente d'un guide-ruban (38). Bien qu'un rouleau de ruban (30) soit maintenu fixe par rapport au mécanisme (28) de manipulation de ruban, (lequel comprend également un mécanisme (32) d'étirement de ruban), un dispositif d'enroulement (52), par déplacement à la moitié de la vitesse verticale du guide (38), assure qu'une longueur constante de ruban (42) se trouve toujours présente sur un mât (24) avant de sortir du guide (38). Un second mât (24) peut être disposé, qui comprend un rouleau de ruban supplémentaire (30), des mécanismes (28, 32), un guide (38) et un dispositif d'enroulement (52), de telle sorte qu'une charge est liée avec un ruban provenant simultanément des deux rouleaux (30). Un système de détection détermine les dimensions de charge avant l'enroulement. Des capteurs détectent les parties avant et arrière d'une charge mobile et déclenchent la prise de multiples mesures de hauteur à différents endroits de la charge.
