  • the present invention relates to packaging apparatus.
  • the present invention may have application to the provision of an automated packaging apparatus for locating product inside bags.
  • the following description is given with reference to a particular implementation of the present invention in relation to the bagging of meat cuts.
  • the present invention may also be applied to the packaging of other products.
  • FIG. 1 of the accompanying drawings a perspective view of a packaging apparatus 1 according to an embodiment of the present invention is shown.
  • the packaging apparatus 1 includes two loaders 1A, 1B for receiving articles to be packaged and a bag receiver 2 for receiving and holding bags.
  • the loaders 1A, 1 B and bag receiver 2 are movable relative to each other and are supported on a frame 3.
  • the frame 3 includes feet 4. From the feet 4 extend legs 5 and the legs 5 at each end of the packaging apparatus 1 terminate at a cross member 6. Extending between the cross members 6 are rails 7, along which the loaders 1A, 1 B may travel. A belt, chain, pulley system or other drive means (not shown) may be used to move the loaders 1A, 1 B along the top of the rails 7 in direction A and along the bottom of the rails 7 in direction B.
  • the frame 3 includes a spacer 8 to separate the ends of the packaging apparatus 1 and a brace 9 may be provided between the legs 5 if required.
  • the rails 7 are mounted on the cross members 6 through plates 10, axles 11 and blocks 12. The rails 7 may be rotated about their longitudinal axis A. A motor belt, chain, pulley system or other drive means may drive a drive wheel 13 in order to effect this rotation. Thus, the loaders 1A and 1 B may move in a reciprocating action along the packaging apparatus 1 above and below the rail 7.
  • the loader clamp 14 includes clamps 15 supported by arms 16. The separation of the clamps 15 is controlled by a ram 17. As is described in more detail herein below, the loader clamp 14 controls the width of the loaders 1 A and 1 B as they travel through the bag receiver 2.
  • loader clamp 14 may be removed from the packaging apparatus 1 and an optical scanning or other sizing device may provide sizing information to robotic bag receiver 2.
  • the bag receiver 2 is located on support members 18A and 18B. Support member 18B is movable vertically upwards relative to support member 18A by pneumatic rams 19.
  • the bag receiver 2 includes two lower arms 20 attached to support member 18A and two upper arms 21 attached to support member 18B.
  • Figures 2 and 3 show a top view and a side view respectively of the packaging apparatus 1.
  • the loader 1A includes a central support or base 22 and two arms 23A and 23B, which terminate in side flanges 24A and 24B respectively. As can be best seen in Figures 4 and 6, the arms 23A and 23B can slide into slots 25 and 26 respectively in order to allow the side flanges 24A and 24B to move inwards and outwards relative to the support or base 22.
  • the loader 1A includes a support assembly 27 that locates the loader 1A on the rail 7. Referring particularly to Figure 6, the side flanges 24A and 24B may be connected to guide members 28A and 28B respectively, which are biased outwardly by springs 29A and 29B.
  • a ratchet (not shown) engages with teeth 30A and 30B to retain the arms 23A and 23B and flanges 24A and 24B in their position against the bias of springs 29A and 29B.
  • Forms of catch other than a ratchet may be used, including frictional engagement or pneumatic rams provided on each loader 1A, 1B to hold the arms 23A and 23B in position. If pneumatic rams are provided on each loader, then the loader clamp 14 may be omitted, with the functions of the loader clamp 14 replaced by the pneumatic rams.
  • loaders 1A, 1B are shown having a generally flat base and vertically extending side flanges 24A, 24B, those skilled in the relevant arts will appreciate that various other profiles may be provided.
  • the loaders may have a concave base.
  • the way that the arms 23A and 23B move together may be varied, with the use of slots 25, 26 not being essential.
  • FIGS 7 to 9 show the loader 1A in a fully closed position, with the separation of the side flanges 24A, 24B at a minimum.
  • loaders may be made that allow increased range of separation of the side flanges 24A, 24B.
  • the structure described herein is anticipated to be suitable for at least the purpose of loading meat cuts into bags.
  • the loader 1A which is seen to be of a platen-type design, receives product from a conveyor (refer Figure 10 for example) such as, but not limited to, a tipping conveyor, a robotic tipping load conveyor, a flat conveyor, a conveyor with a photo eye to measure product length, or other product transport means (not shown) such as, but not limited to, a mechanical sweeping apparatus or a hopper situated above loader 1A.
  • the loader may also be loaded manually.
  • the loader 1A may commence movement along rails 7 in direction A (see Figure 1) in synchronism with the travel of the conveyor.
  • an automated and/or robotic soaker pad placing apparatus may place a soaker pad onto the loader 1A in the case of a meat cut.
  • the loader 1A Once the product has been received by the loader 1A, it moves along rails 7 until it is adjacent to the loader clamp 14.
  • the clamps 15 then move inwards, abutting either the side flanges 24A or 24B or stops 31 A or 31 B (either option can be used depending on the product width) to move the arms 23A and 23B inwards.
  • the loader clamp 14 applies a preset pressure to the loader 1A so that the side flanges 24A and 24B apply the same pressure to the product. This may result in the product, which may be a cut of meat, changing its cross-sectional shape, allowing a smaller bag to be used.
  • the ratchet system engages teeth 30A and 30B to retain the arms 23A and 23B in position after the clamps 15 have disengaged from the loader 1A.
  • a benefit of a platen-type loader 1A is that the meat cut is only exposed across its top surface, as will become apparent below.
  • a bag is loaded onto a bag receiver 2. This may be achieved by an operator retrieving a bag from a bag making apparatus and manually placing the bag onto bag receiver 2 or a bag may be robotically retrieved from a bag making apparatus and robotically placed onto bag receiver 2.
  • the lower arms 20 move outwards as indicated by arrows C and D to approximately the same width as the separation of the flanges 24A and 24B after they have been moved together by the loader clamp 14. Some clearance may be provided if required.
  • the upper arms 21 then move upwards, thereby opening the bag ready for receipt of the loader 1 A.
  • the loader 1 A then moves further along rails 7 through the bag receiver 2, in which case the base support 22 and arms 23A and 23B move into the bag.
  • the loader 1A continues moving along rails 7, taking the bag off the bag receiver 2 so that the bag encapsulates the upper portion of the loader 1 A and the product located thereon.
  • a smaller bag may be used. Also as only the top of the product is exposed in the loader 1 A it is much faster to place the bag over the loader 1A and product than if loading forks were used. Also contact between the product and the bag can be avoided or at least minimised.
  • the bag receiver 2 may be omitted from packaging apparatus 1 and a bag retrieved robotically from the bag making apparatus and placed directly onto loader 1A.
  • the rails 7 are inverted so that loader 1A is in the position that loader 1 B occupies in Figure 1.
  • the bag is held suspended from the loader 1A, at which time it may be removed from the loader 1A by way of a conveyor, including but not limited to a rise and fall conveyor, with or without exit rollers, with or without an elevation option, and possibly a rotation option or by a robotic gripper or by a fixed plate (not shown), and away from the packaging apparatus 1.
  • the loader 1A then travels back along rails 7 and is then inverted to return to its original position for receiving further product.
  • Loader guides 32 may be provided to move the arms 23A, 23B of the loader 1A inwards as it travels back along rails in order to ensure that the loader 1A can fit through the loader clamp 14. If pneumatic rams or other drive means for are provided on each loader, then these could replace the operation of the loader guides 32.
  • the bagged product may be removed manually from loader 1A, by an off loader or conveyor, or a combination of both, or by a robotic gripper (not shown), when loader 1A reaches the end of the rails 7 before inversion.
  • the dimensions of the product are measured prior to the product being received by the packaging apparatus 1. This allows a bag of appropriate dimensions to be produced in advance. Measurement of the dimensions of the product may be achieved by an optical scanning device, located upstream of the apparatus 1 in the processing line.
  • the bag receiver 2 may optionally also receive the product dimensions, in particular the width of the product, so that the lower arms 20 can be moved to a separation equivalent to the product width, plus some amount of clearance.
  • the bag making apparatus 1 may use the position of the arms 23A and 23B after they have been moved together to determine the appropriate sized bag and the bag receiver 2 may use also use that position to set the position of lower arms 20, which may be achieved through direct mechanical engagement, by pneumatic or electronic control or otherwise.
  • This embodiment may result in the bag making apparatus becoming the slowest operation in the processing line.
  • some reduced capital costs may result by measuring the width of cuts in this way, and any delay may be reduced by increasing the length of rails 7 and increasing the separation between the loader clamp 14 (or position where the arms 23A, 23B are moved together) and the bag receiver 2.
  • More than two loaders 1A and 1 B may be provided with appropriate modification of the rail system on which the loaders travel to enable only the loaders at the ends of the rails to be inverted, leaving any that are part way along the rails in the same orientation. This may also assist to increase the throughput of the apparatus 1.
  • a packaging apparatus according to a further embodiment of the present invention is shown diagrammatically and referenced generally by arrow 100.
  • This is shown with a main frame 101 having adjustable feet 121 and supporting a main beam 107 which supports a pair of loaders 103A and 103B, a product sizer assembly 108 and bag receiving means 109.
  • the loaders 103A and 103B are interconnected by a chain or belt travelling within a frame 110 so that movement of the loaders 103A and 103B in opposite directions along the beam 107 can be achieved.
  • the drive includes a rotational drive motor gear box 113, a linear drive motor gearbox 114, a linear drive shaft 115, and a rotational drive shaft 116, provided within a motor housing 118.
  • a linear drive 90° gearbox 111 is shown provided on an opposite side of the end plate 117.
  • a rotary air valve 102 external of a main beam bearing 104 and a main beam end plate 105.
  • a linear drive belt adjuster 106 may suitably be provided at this end of the beam 107.
  • a tipping load conveyor 122 is shown in Figure 10 in its raised position, its position being controlled by a control linkage 217, suitably a pneumatic or hydraulic ram connected with valve 102. It is seen in Figure 10 that there is a clear separation between the horizontal positions of the load conveyor 122 and the loader such as 103A when it is positioned beneath the load conveyor 122.
  • the rotational control of the beam 110 is such that when a loader 103 reaches the end of the beam 110 (right hand end in Figure 10) carrying a bagged product, the beam 110 will rotate through 180° so that the loader 103 will then be in the position shown for loader 103B in Figure 10. Following this the bagged product can be unloaded and discharged onto a suitable exit conveyor 123.
  • a bag unload plate 119 is shown projecting upwardly relative to the inverted loader 103B and controllable by a suitable control linkage 218, such as an hydraulic or pneumatic ram.
  • FIG. 1 This is shown including a mounting post 201 providing a support for a robotic drive motor 202 provided with a drive pulley 203 and a drive belt 204.
  • a drive shaft bearing 205 is shown provided within the drive end conveyor frame 206 including a belt support 207.
  • a suitable support for the frame 206 will be provided such as a brace 208. Operation of the linkage 217 will result in the pivoting of the conveyor 122 from its position shown in Figure 11 to its position shown in Figure 12, this being about an axis 209.
  • a conveyor belt tensioning guide 216 may suitably be provided.
  • the control linkage 217 may in this embodiment be controlled by an air cylinder 214 and with top and bottom end mounts 213 and 215 respectively.
  • operation of the linkage 217 provides for the pivoting downwardly of the conveyor 122 which, as shown for example in Figure 14, is able to facilitate the loading of the product, such as a meat cut, onto the loader 103 which, at this time, will be positioned underneath the front end of the conveyor 122 to receive the product (see Figure 15 for example).
  • a product such as a meat cut 300 is shown in various stages of its passage through the apparatus 100 until it exits as a bagged product 301 on the exit conveyor such as 123.
  • the apparatus 100 is shown including a product identification means 302, such as an optical scanning device, which can measure the size of the product 300 and pass this information to a bag making apparatus 303, so that a bag 304 can be pre-made ready for the arrival of that particular product 300 on the sizer frame 108.
  • the identification means 302 may for example be the CUT-SIZER (TM) apparatus such as described in our international specification WO 01/89930 and the bag making apparatus 303 could include a plurality of machines of the applicant such as described in our international specification WO 94/22723.
  • the information provided to the bag making machines 303 may suitably be such that a specific bag making machine from a gang of machines is selected, depending on the size of the product 300 which is detected, and for this purpose the bag making machines 303 may have supplies of plastic film of different widths. Additionally the information from the apparatus 302 may suitably be such that on the resulting bag 304 will be printed at its time of production, or subsequently, all required information relating to the product 300 including weight, type of cut, grade, identification of the particular carcass or animal, and/or source of supply, by way of example only.
  • the product 300 After travelling through the product identification means 302 the product 300 is shown positioned on the tipping conveyor 122 where its presence is detected by a suitable detection means 305 such as a photo electric eye, although other means could be provided, such as a weight sensing means or the like.
  • a suitable detection means 305 such as a photo electric eye, although other means could be provided, such as a weight sensing means or the like.
  • the detection of the product 300 on the conveyor 122 provides a signal for the tipping of the conveyor 122 (see Figure 14) at which time an operator manually, or an automated system robotically, will have positioned the required bag 304 over the bag holding means 109.
  • FIG. 17 In transferring the product 300 into the bag 304 by means of the sizer frame 108 and the bag receiver 109, reference may be made to Figures 17 to 20 and 21 to 26 particularly.
