Definitions

  • This invention relates to the packaging of compressible materials such as mattresses and foam and spring assemblies used in the manufacture of mattresses and the like, and is more particularly directed to an apparatus for packaging such compressible materials into a roll.
  • Roll packing generally involves winding-up a desired material to form a roll and then securing the roll to prevent uncoiling of the roll during handling.
  • compressible materials such as mattresses and foam or spring cores
  • Various devices have been used to achieve compression of roll packed materials.
  • U.S. Patent No. 3,927,504 to Forrister discloses an apparatus for rolling resilient foamed sheet material without the use of a mandrel. This machine is not useful for packaging spring assemblies and does not have the capability to package multiple units of a compressible material into a large roll.
  • the device further does not provide for packaging a compressible material with a barrier layer between successive turns of the roll, which barrier layer is desirable to prevent adhesion between successive layers of foam.
  • Some roll packing systems further include a mandrel which facilitates winding the material.
  • a spring packing machine having a radially collapsible arbor for use in roll packing spring assemblies. A barrier layer between successive turns of the roll keeps the spring assemblies separate and permits easy removal of a single assembly from the roll.
  • this machine is not useful for roll packing foam material due to the presence of a pressure bar 50, between belt 15 and the collapsible arbor, which would tend to snag a compressed foam as it passed beneath.
  • Roll packing machines of the prior art are generally very labour intensive, requiring the close attention of an operator at various stages of the roll packing process.
  • an operator in the apparatus disclosed by Wunderlich, an operator must manually start the feeding of packing material to a mandrel for winding the spring assemblies into a roll. Operators must also manually feed the compressible spring assemblies to the mandrel and manually cut and secure the packing material at the end of a roll to prevent premature uncoiling of the roll packed assemblies.
  • the operator When a roll of spring assemblies is complete, the operator must remove the mandrel from the machine and manually collapse the mandrel to remove the finished roll. The arbor must then be replaced in the machine before another roll can be formed.
  • US Patent No. 6,098,378 to Wyatt and US Patent No.
  • US Patent No. 2,668,405 to Droll discloses a machine for winding mattresses including a mandrel that can move between expanded and collapsed states using sliding linkages, in accordance with the preamble of appended claim 1.
  • the present invention provides a simple machine for roll packing a variety of compressible materials such as foam cores, spring assemblies, and fiber materials used in the manufacture of mattress products, as well as finished mattresses themselves.
  • the machine has a radially collapsible mandrel that permits finished roll packed materials to be easily removed from the machine by sliding the roll off of the mandrel.
  • This radially collapsible mandrel permits rolled materials to be removed without any telescoping or tearing of the materials which is usually caused by binding of the roll packed material on the mandrel.
  • the machine of the present invention is especially useful in roll packing foam materials which are highly susceptible to binding against a mandrel.
  • the simplicity of design of the machine of the present invention further permits use in roll packing practically any compressible material, even materials as diverse as coiled spring assemblies for mattresses and foam cores.
  • a pneumatic cylinder is used to adjust the position of the compression roller relative to the mandrel.
  • the mandrel is supported on a pivot arm which rotates to vary the spacing between the mandrel and the compression roller.
  • the mandrel is driven at one end by a driving mechanism including, for example, a motor and gearbox, and has a bearing plate at the opposite end.
  • the bearing plate is movable away from the end of the mandrel so that a finished roll of material can be easily pushed off of the mandrel after it has been collapsed.
  • the apparatus includes a roll pusher associated with the mandrel to facilitate the removal of finished rolls from the mandrel, and further includes a roll handler for receiving the finished roll as it is pushed off the mandrel.
  • the invention provides a simple apparatus and method for roll packing a variety of compressible materials and which has a collapsible mandrel that facilitates the easy removal of finished rolls without tearing, telescoping, or otherwise damaging the roll packed material.
  • An apparatus and method are provided for roll packing compressible materials in a simple and efficient manner without damaging the materials, and wherein the materials can be stored and shipped in a compact state.
  • the present invention may be described and understood by a description of an exemplary apparatus.
  • the apparatus 10 includes a collapsible mandrel 12 for receiving in-fed materials 14 and winding them into a roll.
  • the mandrel 12 is fixed to a shaft 16 that is driven at a first end 18 by a driving mechanism, for example motor 20 and gearbox 22 connected to the shaft 16.
  • the invention further includes a compression roller 24, which is located proximate the mandrel 12 and which is fixed to a compression roller shaft 26 that is substantially parallel to the mandrel shaft 16.
  • the rotational axis of mandrel 12 is substantially parallel to the rotational axis of compression roller 24.
  • the compression roller 24 is adjustable such as by means of an actuator 28 fixed to the roller shaft 26 whereby the spacing 30 (see FIGS. 2 and 4A ) between the compression roller 24 and the mandrel 12 may be adjusted to vary or maintain the amount of compression on the in-fed materials 14.
  • a feed table 32 located upstream of the mandrel 12 and compression roller 24 directs in-fed compressible materials 14 between the mandrel 12 and compression roller 24 as the material 14 is wound upon the mandrel 12.
  • the feed table 32 includes a jig plate to ensure proper alignment of the in-fed materials 14 with respect to the mandrel 12 and compression roller 24.
  • a disc brake 34 may be attached to the roller shaft 26 to control rotation of the compression roller 24.
  • the apparatus 10 further includes a packing material dispenser 36 which supplies packing material 38, such as paper, plastic or fiber material, to a surface 40 of the in-fed compressible materials 14 as they are fed through the mandrel 12 and compression roller 24.
  • packing material is then wound with the compressed in-fed material to create a barrier layer between successive turns of the rolled material.
  • the barrier layer protects successive layers of in-fed material such as foam and prevents adhesion of the successive layers.
  • the packing material dispenser 36 may further include a guide roller 42, pinch rollers 44, 46, and a tension roller 48 to aid in directing packing material 38 to the in-fed compressible material 14 and also to maintain proper tension and alignment of the packing material 38.
  • a bearing plate 50 is located at a second end 52 of the mandrel shaft 16, opposite the drive motor 20, and is movable to expose an end of the mandrel 12 so that a finished roll of material 54 may be removed from the mandrel 12.
  • the apparatus further includes a roll handler 58 for facilitating easy removal of the finished rolls 54.
  • the roll handler 58 is a trough-shaped cradle that is pivotally connected to a support (not shown) and can be placed in a first position near the end of the mandrel 12 for receiving a finished roll of material 54.
  • a roll pusher 60 associated with the mandrel 12 aids in removing a finished roll 54 from the collapsed mandrel 12 onto the roll handler 58.
  • the roll handler 58 may then be placed in a second position (shown in phantom) to permit operators to subsequently remove the roll 54 from the machine 10.
  • the collapsible mandrel 12 includes a series of elongated plates 62 attached to the mandrel shaft 16 and positioned about the shaft 16 in an overlapping arrangement to create a substantially tubular surface 64 along the length of the shaft 16.
  • the plates 62 are slidably connected to the shaft 16 and move toward or away from the shaft 16 along radially extending paths 66 to increase or decrease the diameter 67 of the tubular surface 64 formed by the overlapping plates 62.
  • Rods 68 connected to each plate 62 engage a cam 70 attached to the shaft 16, whereby rotational operation of the cam 70 causes the plates 62 to move either toward or away from the shaft 16 to correspondingly collapse or expand the mandrel diameter 67.
  • the spacing 30 between the mandrel 12 and compression roller 24 is adjusted to provide a desired amount of compression in the in-fed compressible material 14.
  • Packing material 38 from the packing material dispenser 36 is fed through the guide roller 42, pinch rollers 44, 46, and tension roller 48 and then directed between the compression roller 24 and mandrel 12 while the mandrel 12 is turned to wind an initial length of packing material 38 upon the mandrel 12, as depicted in FIG 4A .
  • In-fed compressible material 14 which is supported on feed table 32, is directed between the mandrel 12 and compression roller 24.
  • the motor 20 ( FIG.
  • the actuator 28 ( FIG. 1 ) attached to the compression roller shaft 26 may be operated to vary the spacing 30 between the mandrel 12 and compression roller 24 as the roll 54 gets bigger, as can be seen in FIG. 4B , to maintain uniform compression in the roll 54.
  • the motor 20 is stopped.
  • the finished roll 54 is secured, for example, with tape, straps, or other suitable material, and bearing plate 50 ( FIG. 1 ) is moved to expose an end of the mandrel 12.
  • the mandrel 12 is then collapsed, as depicted in FIG. 4C , so that the finished roll 54 may be removed from the mandrel 12 under the operation of the roll pusher 60 ( FIG. 1 ).
  • the roll pusher 60 pushes the finished roll 54 into the roll handler 58 ( FIG. 1 ) and the roll handler 58 then pivots to a second position so that operators can maneuver the finished roll 54 away from the machine 10.
  • the apparatus 110 includes a radially collapsible mandrel 112 for receiving in-fed spring assemblies 114 and winding them into a roll.
  • Collapsible mandrel 112 is attached to a pivot arm 116 having pivot axis 118.
