Definitions

  • ABSTRACT A shouldered wicket for holding a stack of flat flexible articles such as plastic packaging bags or sheets which are to be removed one at a time from the top of the stack, the shoulder portions of the wicket extending upwardly above the rest of the wicket to facilitate article removal from the wicketed stack and the horizontal bearing element of the wicket having a span greater than the linear distance between and across paired wicket holes in the stacked articles.
  • the present invention relates to wickets for holding stacked supplies of flat flexible articles which are to be dispensed or removed from the stacks either manually or automatically one at a time for utilization and more particularly to wickets for holding stacked supplies of flattened flexible plastic packaging articles such as bags or wrapping sheets in readiness for removal and use at industrial packaging stations.
  • wickets whether they are parts of an automatic packaging apparatus or simple bag supply holder device or are furnished along with the packaged prewicketed bags, are as stated above, extremely important elements in these packaging operations as will be readily appreciated by persons familiar with the art.
  • Criteria for wicket design dictate that each bag in turn atop a stack of wicketed bags at a packaging station must be readily removable without the incidental production of bag scraps wnd with clean direct tears through the bag material from the wicket holes to the outer open edge of each holed ply of the bag.
  • the shouldered wickets of Ericson et al. solve many of the problems discussed hereinabove in most normal utilizations and applications.
  • packaging industry however, a significant trend towards the use of packaging bags of thinner gauge materials is discerned, for the obvious reasons of effecting savings in materials, weight and costs.
  • the Ericson et al shouldered wickets are used in conjunction with stacked thin gauge plastic packaging bags for instance, particularly in relatively high speed semiautomatic packaging operations, it has been found that the outermost edge of the bag ply restrainedly held by the wicket horizontal bearing member tends to curl up and wrap itself around the bearing member during bag removal pulling action, causing myriad random stresses which result in unwanted tears, bag scrap production, unuseable bags and production downtime.
  • the present invention was conceived and reduced to practice, having as an object the provision of a wicket to hold stacked flat flexible articles and to permit facile one at a time removal of the articles from atop the stack without damage to the articles.
  • a further object of the present invention is to provide a wicket which is particularly suitable for use in conjunction with automatic and semiautomatic packaging apparatus where the packaging operation proceeds at sustained relatively high speeds.
  • a still further and very important object is to achieve each and all of the aforerecited objects with wickets according to the present invention in conjunction with thin gauge relatively fragile plastic and the like packaging bags.
  • FIG. I is an isometric view showing a wicket embodiment according to the invention in place on a stack of packaging bags.
  • FIG. 2 is a frontal view of an alternative embodiment of wicket according to the invention.
  • FIG. 3 is a side view of the FIG. 2 embodiment.
  • FIG. 4 is a top view of the FIG. 2 embodiment.
  • FIG. 5 is a frontal view of another alternative embodiment of wicket according to the invention.

  • the present invention comprehends a wicket for holding a stack of flat flexible articles provided with paired holes to accommodate wicket leg members, which articles are to be removed one at a time from the stack, said wicket comprising, in com bination; a bearing member adapted to transmit a vertical restraining force in combination with an edge restrain ing member to said stack and having a horizontally extending span greater than the linear distance between the paired holes plus two hole diameters; an article edge restraining member attached to and extending from said bearing member adapted to maintain a portion of an edge of each topmost article in the stack in a substantially flat horizontal disposition as each successive topmost article is forcibly removed from the stack; wicket leg members extending vertically each respectively through the holes in the stack of articles, adapted to hold individual articles therein in substantially registering relationship, said wicket leg members having ends adapted to extend into wicket mounting means and; upwardly extending shoulder members disposed between respective uppermost ends of said wicket leg portions and said bearing member.
  • an article edge restraining member is attached to and extends from each outer end of the span of the bearing member and each shoulder member comprises a first element extending upwardly from an article edge restraining member, a second element connected to and extending upwardly from an upper end of a leg member, and connecting means between the first element and the second element.
  • one or more article edge restraining members bear on the topmost article of the stack at loci other than a line between the paired holes.
  • the article edge restraining member or members comprised in the bearing member and the bearing member itself are adapted to bear on the topmost article of the stack for a total distance less than the overall horizontal span of the bearing member.
  • any and all of the embodiments of apparatus according to the present invention may be fabricated from rod-like stock elements, and, in most instances, advantageously may be connectedly and integrally formed from a unitary rod-like element.
  • FIG. 1 shows an isometric or perspective view of a wicket according to the present invention in place on a stack of flattened flexible plastic bags 11, with a topmost bag 13 of the stack opened, by an air stream for instance, and in readiness to receive an article to be packaged.
  • the wicket shown comprises a bearing member 15 which is adapted to transmit vertical restraining force to the bags 11 and topmost bag 13. This vertical restraining force may be applied to or received by the bearing member 15 in any of several ways ranging from simply weighting the wicket to loading the member with downward pressure with a pivotally cantilevered air nozzle of a machine such as illustrated in the Kupsikevicius application supra.
  • edge restraining members l7, 19 which transmit the vertical restraining force not only to these edges of bag 13, but to the entire stack of bags 11, holding them securely to a wicket base 21.
  • edge restraining member 17, 19 extend from respective ends of the horizontal bearing member 15.
  • Wicket 23, members 23,25 extend vertically each respectively through holes 27, 29 in the stacked bags and are mounted insertably in suitable holes in the wicket base 21, thus holding the stacked bags in substantially registering relationship.
  • each shoulder member comprising, respectively, a first element 31, extending upwardly from an article edge restraining member, a second element 35, 37 extending upwardly from the uppermost portion of each leg member 23, 25 and connecting means 39, 41 joining respective first and second elements.
  • all of the wicket members and elements are connectedly and integrally formed from a single piece of suitably heavy gage wire or rod stock, usually some kind of metal such as steel.
  • FIGS. 2, 3 and 4 of the drawings show a preferred form of wicket respectively in frontal, side and top views wherein the wicket configuration is more rectangular and less arcuate.
  • the outermost edges of the lower ply of a top bag 113 of a stack of bags 111 are contacted and held down by edge restraining members 117, 119 which, as in the case of the aforedescribed FIG. 1 embodiment apply vertical restraining force not only to these edges of the topmost bag 113, but to the entire stack of bags 111, holding them securely to whatever form of wicket base being used.
  • the edge restraining members 117,119 extend from respective ends of a horizontal bearing member 115.
  • Wicket leg members 123,125 extend vertically each respectively through holes 127,129 in the stacked bags and mount in a suitable wicket base.
  • the upwardly extending shoulder members in this embodiment are disposed between the edge restraining members 117,119 and the leg members 123,125, each shoulder member comprising, respectively, a first element 131,133 extending upwardly from an article edge restraining member, a second element 135,137 extending upwardly from the uppermost portion of each leg member 123,125, and connecting means 139,141joining respective first and second elements.
  • FIGS. 1, 2, 3, 4 embodiments upon examination clearly illustrate certain major distinctions and advantages of the wickets according to the present invention over the wickets of Ericson et al mentioned hereinbefore.
  • the horizontal bearing member 15,115 of the present invention may if desired but need not bear on the bags at all but rather function as means to transmit vertical restraining force to the bag stack through and in combination with one or more edge restraining members. This feature permits great flexibility in using bags of varying widths, processed on the same hole making apparatus, with the same hole spacings, in various semiautomatic packaging operations.
  • the length of the horizontal bearing member 15,115 is selectable and this makes wickets according to the present invention adaptable to a wide range of automatic and semiautomatic packaging machinery having varying widths of air nozzles and the like. Wickets according to the present invention then can be tailored to suit a wide range of applications.
  • FIGS. 5, 6 and 7 of the drawings show, respectively, frontal, side and top views of still another alternative embodiment of wicket according to the invention wherein all of the members and elements as shown 215, 217, 219, 223, 225, 231, 233, 235, 237, [239] and 241 are cooperatively arranged as in the first described FIG. 1 embodiment and, in addition, an edge restraining member 217a is included and functions as hereinabove described in respect of the FIGS. 2, 3, 4 embodiment.
  • FIG. 8 of the drawings shows in schematic plan view the bearing areas 217, 217a and 219 on the upper surface of the lower ply of a topmost bag 213 of a stack of bags 211 according to the manner occasioned in the use ofa FIG. 5, 6, 7 embodiment wicket and illustrates clearly the advantage in bag restraining mode made possible by the present invention.
  • FIG. 9 shows isometrically a FIG. 2,3,4 wicket embodiment in position on a stack of bags unpacked from shipment and ready to be installed at a bagging station.
  • a wicket leg keeper 124 is provided as shown to keep the bags on the wicket during shipment and handling.
