Definitions

  • the present invention relates generally to product wrapping systems and, more particularly, to systems for dispensing wrapper stock onto product rolls that require wrapping. Such systems are typically capable of wrapping rolls of varying lengths and diameters.
  • FIG. 1 A current system for wrapping product rolls, such as paper rolls, is depicted in Fig. 1.
  • Product roll 150 has a typical cylindrical shape with its round end face 1501 being shown in Fig. 1.
  • a length in the axial direction of product roll 150 runs perpendicular to the plane of the drawing sheet.
  • wrapper supply rolls 101-104 having multiple widths of wrapper stock 121-124, respectively, are typically staged at an overhead (or rear) location near a wrapping station 140.
  • the wrapper stock can be paper or plastic film.
  • the widths of wrapper stock 121-124 are also measured in the axial directions of the respective wrapper supply rolls 101-104, which in Fig.
  • wrapper supply rolls 101-104 and product roll 150 are arranged with their axes running parallel.
  • the wrapper supply rolls 101-104 are typically arranged with respect to a centerline 149 (Fig. 1A) of wrapping station 140 so that the centerline 149, which runs parallel to the plane of the drawing sheet containing Fig. 1 and perpendicular to the axes of the wrapper supply rolls 101-104, would bisect the widths of all wrapper stock 121-124. This arrangement is shown in Fig.
  • wrapper supply rolls 101 and 102 are arranged with the centerline 149 of wrapping station 140 bisecting their widths.
  • Product roll 150 must then be centered with respect to the centerline of wrapping station 140 so that the centerline also bisects the length of the product roll 150.
  • both end faces 1501, 1502 (Fig. 1A) of the product roll 150 can be properly wrapped.
  • the proper width of wrapper stock e.g., 121, is identified, either manually or automatically, and selected for dispensing through a number of bend rollers 131-133, 161-164 (Fig. 1) onto product roll 150.
  • the bend rollers 131-133, 161-164 are typically idler rollers, and are used to guide the wrapper stock through a zigzag path, e.g., 101-131-161-145, into the wrapping station 140. More particularly, the bend rollers are rollers at which the wrapper stock changes its direction. In system 100, there are other rollers that also guide the wrapper stock but do not change its direction. These rollers are called support rollers designated at 181-184.
  • the currently available technology typically utilizes a series of wrapper hackstands or dispensing stations 120 and a wrapping station 140 that requires that the multiple wrapper stock widths 121-124 be pre- fed into the wrapping station 140.
  • the dispensing stations 120 are capable of feeding any single width, e.g., 121, selected for dispensing. This can be done by rotating the selected wrapper supply roll, e.g., 101, to unwind wrapper stock 121.
  • Fig. IB shows an alternative, low-profile arrangement of the conventional wrapping system, in which the dispensing station 120 and wrapping station 140 are generally co- elevational.
  • One problem with existing systems of the above type relates to the process required to pre-feed many different widths of wrapper stock, 121-124, into one machine, e.g., wrapping station 140, and the process required to replenish wrapper stock.
  • many different widths of wrapper stock, 121-124 are pre-fed into wrapping station 140.
  • the proper width wrapper stock, e.g., 121 is selected, only wrapper stock 121 will be fed between turning rollers 170 and product roll 150 to wrap the product roll.
  • the other, unselected widths of wrapper stock 122-124 need to be present in wrapping station 140, ready for dispensing in case one of them will be selected in the next wrapping operation of a product roll having a different length.
  • the dispensing and wrapping operations are usually performed automatically in a known manner, i.e., an automatic controller (not shown) determines the length of product roll 150, selects the proper width of wrapper stock 121, controls the dispensmg of the wrapper stock 121 from the respective wrapper supply roll 101 and its feeding into wrapping station 140, and, after product roll 150 has been completely wrapped and discharged to warehouse, repeats the process for the subsequent product roll.
  • a second problem with these systems is the fact that large areas of wrapper stock are left exposed to the ambient environment, for example, with respect to wrapper stock 121, in the areas 191 (Fig. IB) between bend rollers 131-161 and wrapping station 140. In the case of Kraft paper wrapper stock, this can result in loss of moisture content which adversely contributes directly to wrapped package quality, (i.e. edge crimping of the final package is inferior when moisture content falls too low).
  • a third problem with these systems is that the pre-fed wrapper stock is often left resting on the floor and is dragged on the floor which can result in the introduction of contaminants on the wrapper stock. This can be seen again in Fig. 1, in the areas 191 between bend rollers 131 and 161.
  • a fourth problem with these systems is that the pre-fed wrapper stock, e.g., 121, is directed across the bend rollers, e.g., 131-161, to feed it into the wrapping station 140. It is a common problem with wrapper left bent over a roller (especially bend rollers 131-134) for it to take a slight "set” around the bend roller such that it is slightly deformed. The deformations will be more likely to become permanent if the wrapper, e.g., 124, is not used for a long time, e.g., because its width is not suitable for wrapping a series of product rolls.
  • a fifth problem with these systems is the difficulty of clearing jams and mis-feeds of wrapper.
  • wrapping station 140 that has multiple sheets pre-fed at the same time into a single area (e.g., 141), by its nature, the internal fingers (at 145) of wrapping station 140, that are required to guide and separate the multiple wrappers inside the wrapping station of dispenser 140, leave little room for wrapper build up during a jam or mis-feed.
  • the access to the internal components of most dispensers is very limited as can be seen in Fig. 1 at 145. Consequently, the time it takes to clear a jam can be as high as 30 minutes or more. The process of clearing the jam can even lead to damaging of the drive rollers, fingers, or wrapper guides inside the wrapping station 140, e.g., in the region generally designated by reference numeral 145.
  • a sixth problem with these systems is the means by which the wrapper, e.g., 121, is tensioned as it is applied to the product roll 150. Typically, this is accomplished by variable speed control between the wrapping station 140 and/or backstand/dispensing stations 120 and the drive of the turning rollers. If there is a mismatch of speeds between the drives, wear occurs on the drive rollers 170, which are often rubber covered for gripping. Consequently, the drive rollers must be replaced regularly and if a particular wrapper width is used frequently, then the corresponding drive roller also has to be replaced more frequently. This translates to a higher cost of repair.
  • FIG. 1A schematically shows an overlap wrapping operation. First, ultra wide product roll 150 is placed in Position A so that a part 157 thereof can be wrapped with wrapper stock 121 dispensed from wrapper supply roll 101.
  • the product roll 150 must be moved relative to the centerline 149 of the wrapping station 140 and dispensing stations 120 (not shown in Fig. 1 A), i.e., in the axial direction of the product roll to Position B where another part of product roll 150, i.e., 158, can be wrapped with wrapper stock 122 dispensed from wrapper supply roll 102.
  • the overlap part 159 is where the product roll 150 is wrapped with both wrapper stock 121 and 122.
  • the movement of product roll 150 from Position A to Position B requires that the product roll be handled with additional equipment. Because the product rolls can weigh up to several thousand pounds, this means higher initial cost for the system as well as another long-term maintenance cost of repair.
  • an apparatus for feeding a wrapper stock (or wrapping web) to a wrapping station where a product is to be wrapped with the wrapping web comprises a hackstand for holding a supply roll of the wrapping web and for unwinding and rewinding the wrapping web from the supply roll, and a conveyor for transporting the wrapping web unwound from the supply roll to the wrapping station.
  • the conveyor comprises a vacuum conveyor belt, or an electrostatic conveyor belt, or a moving belt having a non-skid surface, or the like.
  • the wrapping web is dispensed from the supply roll to the conveyor along a path which is free of bend rollers.
  • the apparatus further comprises an elongated guiding element having a first end located below and adjacent the hackstand for receiving a lead edge of the wrapping web, and a second, opposite end located above and adjacent the conveyor for guiding the lead edge of the wrapping web to fall under gravity onto the conveyor.
  • the hackstand comprises two chuck portions and a driving mechanism for driving the chuck portions, hi chucking motion, the chuck portions are driven by the driving mechanism to move relative to each other to engage a core of the supply roll, the chuck portions being adapted to rotate the core in opposite directions to unwind and rewind the wrapping web, respectively, hi shuttling motion, the driving mechanism drives the chuck portions along an axial direction of the product roll, without changing the distance between the chuck portions, to adjust to a length of the product to be wrapped, e.g., when overlap wrapping is required.
  • the driving mechanism comprises two elongated, threaded shafts, a motor and a transmission box.
  • Each of the chuck portions is movably arranged on one of the shafts.
  • the transmission box selectively transmits torque between the motor and both of the shafts, thereby effecting the chucking motion of said chuck portions toward or away from each other and the shuttling motion of said chuck portions together along the axial direction of the product to be wrapped.
  • One or more of the above and other objects of the present invention are also achieved by a method of wrapping a product with a wrapping web stored on a supply roll.
  • the method comprises unwinding the wrapping web from the supply roll; feeding a lead edge of the wrapping web to a wrapping station using a conveyor; and wrapping the product with an unwound length of the wrapping web.
  • the feeding step comprises allowing the lead edge of the wrapping web to fall under gravity directly on the conveyor; and using the conveyor to transport the lead edge and, successively, the unwound length of the wrapping web to the wrapping station.
  • the method further comprises cutting the wrapping web after the wrapping has been completed; and rewinding an unused portion of the unwound length of the wrapping web onto the supply roll, leaving a short length of the wrapping web dangling loosely above the conveyor.
  • the method further comprises controllably varying the unwinding speed of the supply roll and/or the moving speed of the conveyor and/or the wrapping speed of the turning rollers, depending on a position of the lead edge of the wrapping web on the conveyor, thereby tensioning the wrapping web.
  • the conveyor includes a vacuum belt
  • the vacuum strength of the vacuum belt can also be regulated to maintain positive control of the wrapping web, depending on the position of the lead edge of the wrapping web on the belt.

  • the wrapping webs or wrapper stock is dispensed from one supply roll at a time onto a moving conveyor which transports the wrapper stock to a wrapping station without using bend rollers, hi accordance with an unique aspect of the present invention, after the wrapping operation has been completed, the wrapper stock is rewound onto its supply roll, rather than being left exposed on the conveyor or in the wrapping station.
  • Another novel feature of the present invention resides in the unique arrangement in which the supply rolls, rather than the product roll, are shifted for overlap wrapping.
  • the present invention advantageously provides a novel wrapping system and method in which the wrapping web can be automatically fed on demand to the wrapping station without human intervention and without the need for pre-feeding the wrapping web into the wrapping station before the proper width of wrapper stock is selected.

  • dispensing station 220 can also include a spare wrapper roll holding pocket 225 to hold a spare supply roll 215.
  • the supply rolls 211-215 are transported to the hackstands 221-224 or spare wrapper roll holding pocket 225 by an overhead transporting mechanism 216.
  • the transporting mechanism 216 generally includes an overhead rail 2161 extending immediately above each of the hackstands 221-224 and holding pocket 225.
  • a clamp 2162 moves along the rail 2161. Any other means for transporting supply rolls to the dispensing station 220, e.g., conveyors, can be used with the present invention.
  • Each of hackstands 221-224 is provided with a wrapper stock deflection chute 231- 234, respectively, into which the free or lead edge of wrapper stock is fed down under the force of gravity.
  • the chute's function is to introduce the lead edge of the wrapper stock down onto a wrapper conveyance system or conveyor 250 at an obtuse angle, e.g., a3 (Fig. 2), to the ranning direction, e.g., d2 (Fig. 2), of the conveyor. Additionally, the chute's function is to control the degree of curl on the lead edge (e.g., 2015, Fig. 11 A) of the wrapper stock (e.g., 201) in the chute.
  • each chute includes at least one elongated metal sheet, as can be seen in Fig. 5 at 531-534.

  • the surfaces of the elongated metal sheets that may come into contact with the wrapper stock e.g., the inwardly facing surfaces of metal sheets 2341-2342) are generally planar and should not obstruct smooth movement of the wrapper stock through the V-shaped structure down to the conveyor.
  • the V-shaped structure of the chutes includes an inlet, e.g., 2343 (Fig. 2), adjacent and below the respective supply roll 214, and a outlet, e.g., 2344, adjacent and above the respective section (252) of conveyor 250.
  • Each of the supply rolls 211-214 are positioned in the respective hackstands, 221-224, so that the free or lead edges of the wrapper stock of the supply rolls 211- 214 dangle loosely in the V-shaped structures of the respective chutes 231-234.
  • wrapper stock 201-204 are all drawn down to the conveyor 250, it should be understood that only one of the wrapper stock, e.g., 201, is drawn down to and carried by conveyor 250 to wrapping station 240 at a time.

  • the use of bend rollers as well as the wrapper deformation problem associated therewith are thus advantageously avoided in accordance with the present invention.
  • Conveyor 250 is located directly beneath all of the hackstands 221-224 such that wrapper stock fed down (under gravity and by rotating the respective supply rolls in an appropriate direction, e.g., counterclockwise) from any of the wrapper stock rolls or supply rolls 211-214 will be received on moving conveyor belts 251-252 of conveyor 250. Vacuum, electrostatic, non-skid surfaces or other means, are employed by conveyor 250 to maintain positive control of the wrapper stock as it makes contact with the upper runs of the conveyor belts.
  • Conveyor 250 includes primary feed belt 251, secondary feed belt 252, intermediate belt 253 and belt finger table 254.
  • the primary feed belt 251 and secondaiy feed belt 252 are preferably vacuum conveyor belts that are mounted below the hackstand structural support 229.
  • the primary vacuum feed belt 251 will preferably run continuously regardless of which hackstand is paying out wrapper stock.
  • the primary feed belt 251 is also the main feed conveyor for the leftmost hackstand 221.

  • the secondary feed belt 252 and/or the intermediate belt 253 and the belt finger table 254 may run continuously as well.
  • Each of the conveyor belts includes an endless belt 2531 trained around two pulleys 2532, 2533, each having a rotational axis that is arranged generally horizontal.
  • One of the pulleys, e.g., 2532 is a driving pulley which is driven by a conveyor belt drive (not shown), e.g., a motor.
  • the other pulley, e.g., 2533 is an idler which is driven by the driving pulley 2532 and the endless belt 2531. It is also within the scope of the present invention to provide both pulleys 2532-2533 as driving pulleys.
  • the conveyor belts can have separate pulleys, e.g., conveyor belt 254, or shared pulleys, e.g., pulley 2532 which is shared between conveyor belt 251 and conveyor belt 253.
  • Each of the conveyor belts has an upper run 2534 and a lower run 2535.
  • the upper run 2534 runs from the infeed location 2532 to the outfeed location 2533, positively controls and carries the wrapper stock's thereon in the running direction, e.g., d3, of the conveyor belt 253.

  • the outfeed location of an upstream conveyor belt, e.g., 251 is placed adjacent the infeed location 2532 of the next, downstream conveyor belt, e.g., 253, to ensure smooth transition of the wrapper stock from the upstream conveyor belt to the next downstream conveyor belt 253.
  • the outfeed location 2523 of an upstream conveyor belt, e.g., 252 can be placed adjacent and above the upper run and in a middle region 2516 of the next, downstream conveyor belt, e.g., 251.
  • the last conveyor belt 254 has a outfeed location 2543 that is adjacent the nip 320 between turning rollers 321/322 and product 2010 so as to smoothly transfer the wrapper stock into the nip.
  • the wrapper slitter 362 and dual hot melt glue gun system 363 are positioned in a region between the outfeed location 2533 of conveyor belt 253 and the infeed location 2542 of the last conveyor belt 254.
  • An advantage of this arrangement resides in that if glue guns drip, they will not drip on the belting material of conveyor belts 253-254. Rather, all glue drips will pass between the conveyor belts 253- 254 and will be collected in the underlying glue drip pan 364.
  • All of the downstream vacuum belt conveyors (253, 254) are successively engaged, after wrapper stock is pre-fed from the overhead primary vacuum feed belt 251, to secure the lead edge of the wrapper stock in a vacuum pinning action and maintain control of the wrapper stock as it is accelerated down and into the nip of the turning rollers 321-322.
