Definitions

  • the present invention generally relates to a supply roll engagement system which is useable in a sheet material dispenser which dispenses sheet material from a rolled web material product, such as a paper towel or toilet tissue.
  • Dispensers have become more specialized and are being designed by manufacturers to dispense a sheet material from a roll of a particular web material product. As a result, the dispenser's operation is optimized for a particular rolled product or suite of rolled products. If a different rolled product, for example a rolled product of a different product manufacturer, is inserted into the dispenser, the dispenser may not function properly. For example, the product may become jammed in the dispenser or the cutter blade in the dispenser will not properly cut the product being dispensed.
  • the manufacturer of the electronic hands-free dispensers wants to use a motor which is an appropriate size to dispense the rolled product the dispenser is designed to dispense.
  • a motor which is appropriately sized the power needed to dispense a sheet from the rolled product is kept to a minimum. If the motor is too big, the power consumption of the dispenser will be higher than needed to dispense the sheet material. If the motor is too small for a given sheet material, the motor may be damaged during the dispensing operation. In addition, as is the case with a motor that is too large, the energy needed to dispense a sheet material with a motor that is too small will also be larger than needed.
  • a supply roll of web material may be inserted into the dispenser one of two ways, web-front or web-back.
  • Web-front is when the web material is feed to the dispensing rollers of the dispenser such that the web material comes from the supply roll closer to the front of the dispenser.
  • web-back the web material comes from the supply roll closer to the back of the dispenser.
  • Each individual dispenser may be optimized for a web-front configuration or a web-back configuration. In some cases, if the web material is placed in the dispenser in an incorrect orientation, the web material may become torn or may become jammed in the dispensing mechanism. There is a need in the art to ensure that the roll of a web material, such as paper towels or toilet tissue, is properly placed in the dispenser to prevent unwanted jams and tears in the sheet material.
