  • This invention provides a process for making a unitary [22] Filed: Apr. 4, 1973 package which comprises a load that has a band formed of plural layers of a stretched material [21] App1'NO"347873 wrapped around it. Basically the process comprises the steps of: placing a load on a support; locating a [52] US. Cl. 53/27, 53/30 rolled-up sheet of stretchable material on dispenser [51] Int.
  • Cl B65b /06 means adjacent to the support; withdrawing a leading [58] Field of Search 53/27, 30, 33, 184,211, edge of the material from the dispenser means and 53/212, 214; 242/7543 holding that leading edge against the load; initiating substantially unrestricted relative movement between [56] References Cited the support and dispenser means to cause a sufficient UNITED STATES PATENTS amount of the material to overwrap at least a part of the load; subsequently continuing the relative movegg g ment but restricting it such that the material will then 6:032 12/1963 i h rug/7543 be stretched and causing a sufficient amount of the 1 3 9 g Hairless 2 5 stretched material to be dispensed from the dispenser 3,495,375 2/1970 Burh0p 53/33 means to provide a band comprising plural layers of 3.5l4.920 6/1970 Hoffler
  • the present invention is also directed toward a prod- 3,68,. 33 8/1972 Lassig 53/33 uct that is produced by this process and to Certain paratus which can be utilized to perform this process.
  • shrink-palletizing processes and basically comprise unitization of a palletized package load by first overwrapping it with a heat shrinkable material which is then tightly shrunk against the package load by applying sufficient heat to the overwrapped load to raise its temperature to the heat-shrinking temperature of the overwrapping material.
  • Our co-pending, commonly assigned US. Patent application Ser. No. 295,532, filed Oct. 6, 1972 describes a most recent and efficient form of such shrink-palletizing systems; while older forms thereof have been described in detail in US. Pat. Nos. 3,514,920; 3,581,458; 3,590,549; 3,626,654; 3,640,048; 3,662,512; and 3,670,880.
  • the trailing edge or edges of the bandforming overwrapping material must be fin-sealed (as opposed to lap-sealed) along substantially their entire width and this requires elaborate clamping and sealing means.
  • tension is not evenly applied to the material forming the overwrapping band.
  • the sharp edges of the surface of the overwrapped package load tend to pierce the single layer of the tensioned wrapper band as it is dispensed therearound.
  • the present invention is particularly concerned with providing an improved process for producing a unitary vides similar advantages over the aforedescri-bed shrink-palletizing systems, but which also eliminates the aforenoted problems which have heretofore plagued the earlier forms of stretch-palletizing" systerns.
  • the present invention provides a process for making a unitary package which comprises a load that has a band formed of plural layers of a stretched material wrapped around it.
  • the process comprises the steps of: placing a load on a support; locating a rolled-up sheet of stretchable material on dispenser means adjacent to the support; withdrawing a leading edge of the material from the dispenser means and holding that leading edge against the load; initiating substantially unrestricted relative movement between the support and dispenser means to cause a sufficient amount of the material to overwrap at least a part of the load; subsequently continuing the relative movement but restricting it such that the material will then be stretched and causing a sufficient amount of the stretched material to be dispensed from the dispenser means to provide a band comprising plural layers of the material around the load; and fastening the trailing edge of the dispensed stretched material to at least one of the previously dispensed band-forming layers.
  • the present invention is also directed toward a product that is produced by this process and to certain apparatus which can be utilized to perform this process.
  • FIG. 1 is a somewhat schematic partly broken elevational perspective view showing a presently preferred form of apparatus that can be utilized in performing the novel process of the present invention to produce its novel unitary package, which comprises a load that has a band formed of plural layers of a stretched material wrapped around it, and illustrates the apparatus just following completion of the process;
  • FIG. 2 is a greatly enlarged fragmentary elevational view showing in detail the construction of the presently preferred forms of the overwrapping film dispenser means, restricting means for causing stretching of the dispensed film, control means for selectively adjusting the restricting means and cutter means for severing the dispensed material from the dispenser means of the apparatus shown in FIG. 1;
  • FIG. 3 is a fragmentary sectional view taken along line 3-3 of FIG. 2;
  • FIG. 4 is a schematic top plan view of the apparatus of FIG. 1 illustrating it in a first condition of operation
  • FIG. 5 is a view similar to that shown in FIG. 4, but showing the apparatus in another condition of operation;
  • FIG. 6 is a view similar to that shown in FIGS. 4 and 5, but showing the apparatus in yet another condition of operation;
  • FIG. 7 is a greatly enlarged fragmentary sectional view taken along line 7-7 of FIG. 7;
  • FIG. 8 is a greatly enlarged fragmentary sectional view taken along line 8-8 of FIG. 5;
  • FIG. 9 is a greatly enlarged fragmentary sectional view taken along line 9-9 of FIG. 6.
  • FIG. 1 there is illustrated, with parts broken away for purposes of illustration, a typical product, a unitary package 10, which can be produced in accordance with the novel process that is provided in accordance with the present invention. While it should be understood that various means could be employed, FIGS. l-9 of the drawings illustrate a form of apparatus 11 that has been used with good results in carrying out the novel process of the present invention to produce the product 10.
  • the product comprises a palletized load of plural boxes 12 built upon a skid l3 and has its generally vertically arranged portion overwrapped by a band 14 formed of plural layers of a stretched sheet of stretchable material 15 wherein the trailing edge 16 of the stretched material 15 is fastened to at least one of the previously wrapped band-forming layers of the material 15.
  • the material 15 is of a type that is heat laminateable and this fastening is performed by heat sealing means 17a (FIG. 6) which provides a plurality of fastening heat seals 17 that are aligned at an angle with respect to the trailing edge 16 of the sheet of material 15 and are spaced apart from one another.
  • the presently preferred form of apparatus 11 that can be employed to perform the process of the present invention to produce the product 10 basically includes a support means 18 for supporting the package load 12', dispenser means 19 for locating a rolled-up sheet of the material 15 for movement relative to the support means 18; drive means 20 for initiating substantially unrestricted relative movement between the support 18 and dispenser means 19 to cause a sufficient amount of the material [5 to be dispensed from the dispenser means 19 overwrap at least a part of the load 12 (FIG. 4); and restricting means 21, such as a brake best shown schematically in FIGS. 4-6 for restricting continuation of the relative movement such that the material 15 will then be stretched (FIG. 6) but permitting a sufficient amount of the stretched material 15 to be dispensed from the dispenser means 19 to provide the band 14 comprising plural layers of the material 15 around the load 12 (FIGS. 1, 6 and 9).
  • the support means 18 preferably comprises a generally horizontally arranged platform 22 which can support the skid 13 for rotary movement about a generally vertically arranged axis.
  • the platform 22 is supported on a vertical axle 23 journaled in a bearing 24 centrally located in a base 25 for the support means 18 and is suitably interconnected to the drive means 20, which can comprise a rotary electric motor 26 or other suitable means, for substantially unrestricted rotary movement around the generally vertical axis of the axle 23 (in a clockwise direction as viewed in FIGS. 4-6).
  • the dispenser means 19 comprises a generally vertically arranged member or shaft 27 that is mounted on a base frame 28 located adjacent to the support means 20 for substantially unrestricted rotary movement relative thereto about a generally vertical axis.
  • the upper end of this shaft 27 removably receives the lower end of and generally vertically supports a rolled-up sheet of the stretchable material 15, while the upper end ofthe rolled-up sheet is rotatably journaled by an upper journal member 29 which is mounted for slidable vertical movement relative to the base frame 28.
  • This illustrated construction provides the dispenser means 19 with height adjustable means for mounting overwrapping material of various widths to thus accomodate overwrapping of package loads 12 of various heights.
  • the presently preferred form of the restricting means 21 that are employed in the apparatus 11 comprise brake means which are provided adjacent the lower end of the dispenser means rotary shaft 27. As best shown in FIGS. 4-6, these illustrated restricting means 21 comprise a brake drum 30 which is fixed on the lower end of the dispenser means shaft 27 for rotation therewith and that can be engaged and disengaged by a brake shoe 31 which is carried by a brake lever 32 that is pivotally mounted to the dispenser means frame 28.
  • the brake shoe 31 that is carried by the lever 32 is yieldably urged out of engagement with the brake drum 30 by a first tension spring 33 (FIGURE 4) to thus permit substantially unrestricted rotary movement of the dispenser means shaft 27.
  • a first tension spring 33 (FIGURE 4) to thus permit substantially unrestricted rotary movement of the dispenser means shaft 27.
  • the yieldably urging of this first spring 33 can be overcome and the brake lever 32 can be pivoted to engage the brake shoe 31 carried by it with the brake drum 30 through movement of a cable 34 which has one of its ends connected to the pivoted brake lever 32.
  • the brake cable 34 has its other end connected to a brake operating arm 35 that is pivotally mounted with respect to the dispenser means frame 28.
  • the brake cable operating arm 35 is, in turn, yieldably urged by a second tension spring 36 in a direction causing the brake cable 34 to move the brake lever 32 with sufficient force to overcome the urging of the first spring 33 and thus cause engagement of the levercarried brake shoe 31 with the brake drum 30.
  • this second tension spring 36 is connected between the dispenser frame 28 and the brake cable operating arm 35 by adjustable control means, such as the illustrated jack screw 37 and wire 38 and pulley 39 arragement, whereby the brake engaging counter-force which it provides with respect to the brake disengaging force of the first spring 33 can be readily adjusted.
  • a brake release device 40 is also pivotally mounted to the dispenser frame 28 which can be releasably engaged with the brake cable operating arm 35 to completely overcome the counter of the second spring 36 and allow the first spring 33 to fully release the lever-carried brake shoe 32 from engagement with the brake drum 30 (FIG. 4
  • the brake cable operating arm 35 rotatably journals a generally vertically arranged roller 41 over which the leading edge of the rolled-up sheet of material can be first threaded prior to its engagement with the package load 12 at the commencement of the process of the present invention.
  • the brake or restricting means release device 40 is preferably engaged with the brake cable operating arm 35 as shown in FIG. 4, to thus permit substantially unrestricted relative movement between the support 18 and dispenser 19 means upon energization of the drive means 20.
  • the brake release device 40 is pivoted, as shown in FIG.
  • an operator first mounts a rolled-up sheet of the material 15 having a width sufficient to cover at least the vertical portion of the package load 12 on the shaft 27 and upper journal member 29 of the dispenser means 19.
  • the operator utilizes a fork-lift truck or other suitable conveyor means to place the package load 12 and its skid 13 atop the platform 22 of the support means 18 to align its center generally over that of the platform axle 23.
  • the operator moves the brake release device 40 into engagement with the brake cable operating arm 35 as shown in solid lines in FIG. 4 and in shadow lines in FIG. 3 to fully release the restricting means 21 and permit substantially unrestricted rotary movement of the dispenser means shaft 27 and upper journal member 29.
  • the operator withdraws the leading edge of the rolled-up sheet of the material 15 from the dispenser means 19 and, having first threaded it over the brake cable operating arm roller 41 as shown in solid lines in FIG. 4 and in shadow lines in FIG. 3, holds that leading edge against the vertical surface ofthe package load 12 either manually or with fastener means (not shown).
  • the operator energizes the drive means 20 in a well-known manner through closure of switch means (not shown) which cause the drive means motor 26 to initiate rotation of the support means platform 22 and the package load 12 and skid 13 carried by it about the generally vertical axis of the platform shaft 23.
  • This causes substantially unrestricted relative movement between the support means 18 and the dispenser means 19 such that a sufficient amount of the rolled-up material 15 will be unwound or dispensed from the dispenser means 19 through the substantially unrestricted rotary movement of the support means platform 22 and the dispenser means shaft 27 and upper journal member 29 to overwrap at least a part of the package load 12.
  • this substantially unrestricted movement is allowed to continue approximately one revolution of the support platform 22 and the package load 12 carried by it whereby a band comprising a single unstretched layer of the material 15 is overwrapped around the generally vertically arranged portion of the package load 12.
  • the operator can with a separate wrapper, such as an overcapping sheet 43, overwrap a portion of the package load 12 (the top of the package load 12 as illustrated) not previously overwrapped by the sheet of material 15.
  • a separate wrapper such as an overcapping sheet 43
  • the operator pivots the brake release device 40 out of engagement with the brake cable operating arm 35, as shown in solid lines in FIGS. 3, 5 and 6, activating the restricting means 21 as previously described above, and continues energization of the drive means 20 and thus provides continuous but now restricted relative movement between the support 18 and dispenser means 19 such that the dispensed sheet material 15 will then be stretched and causing a sufficient amount of the stretched material 15 to be dispensed from the dispenser means 19 to provide the band 14 which comprises plural layers, including at least one outer stretched layer, as shown in FIG. 1, of the material 15 around the package load 12.
  • the operator fastens the trailing edge 16 of the stretched dispenser material 15 in an overlapping seal to at least one of the previously dispensed band-forming layers.
  • this fastening is preferably performed by heat sealing, assuming the material is a heat laminateable material such as polyethylene, and the heat-sealing step is performed manually by the operator with means such as the illustrated heat-sealing device 1741 to provide the plurality of fastening heat seals 17 that are aligned at an angle (approximately a 90 degree angle) with respect to the width of the trailing edge of the dispensed material sheet 15 and are spaced apart from one another therealong.
  • the operator now severs the overwrapped package from the dispenser means, as by employing the illustrated dropknife cutter means 44 which is preferably mounted adjacent the support means 19 and finally de-energizes the drive means 20.
  • the novel overwrapped product (FIG. 1) that is produced by the novel process of the present invention can now be removed from the support means platform 22 by a fork-lift or other suitable conveyor means.
  • the operator can selectively adjust the restrictive effect of the restricting means 21 through operation of the jack screw 37 of the aforedescribed control means to thereby selectively alter the degree of elongation of the stretched dispensed material 15.
  • a process of making a unitary package comprising the steps of:
  • thermo sealing provides a plurality of fastening heat seals that are aligned at an angle with respect to said trailing edge and are spaced apart from one another.
