Abstract
In one aspect, the present disclosure is directed to a sheet material dispenser that includes a feed roller that is rotatable to facilitate dispensing of the sheet material from a discharge in a housing of the dispenser. The dispenser can have a cutting assembly that includes a cutting blade and at least one movable support coupled to cutting blade and that is actuated with rotation of the feed roller to cause movement of the cutting blade to at least partially cut, score, or perforate the sheet material during dispensing thereof. The dispenser also can have a biasing assembly coupled to the feed roller body to assist rotation of the feed roller body and/or movement of the cutting blade. Other aspects also are described.
Claims19
A dispenser for dispensing a sheet material, the dispenser comprising:
- a feed roller configured to feed the sheet material from a supply of sheet material along a path of travel to a discharge, the feed roller comprising a feed roller body having a chamber defined therein,
- a cutting assembly comprising:
- a cutting blade at least partially disposed within the chamber, and
- at least one moveable support coupled to the cutting blade;
- wherein the at least one moveable support comprises a first portion positioned along an interior surface of the feed roller body, and a second portion configured to move along a cam track located within the chamber;
- wherein the cutting blade is at least partially positioned within the chamber and is moved with rotation of the feed roller from a retracted position to an extended position extending at least partially through one or more openings defined in the feed roller body to at least partially cut, score, or perforate the sheet material during dispensing of a selected portion thereof;
- and
- a biasing assembly including:
- at least one biasing member coupled to the feed roller body;
- at least one linkage having one end connected to the at least one biasing member and an opposing end that is substantially fixed against rotation;
- and
- at least one pulley adapted to engage the at least one linkage and facilitate a change of direction of the at least one linkage to convert a tension force applied by the at least one biasing member to a radial pulling force to assist in one or more of:
- rotation of the feed roller body;
- or
- facilitate movement of the cutting blade through the one or more openings of the feed roller body.
A sheet material dispenser, comprising:
- a dispenser housing having a discharge;
- a supply of sheet material received within the dispenser housing;
- a feed roller rotatably mounted within the dispenser housing, the feed roller comprises a feed roller body having a chamber defined therein, and an exterior surface along which the sheet material is engaged;
- wherein, the sheet material is fed from the supply of sheet material along a path of travel toward the discharge by rotation of the feed roller;
- a cutting assembly comprising:
- a cutting blade at least partially received within the chamber of the feed roller body and moveable into and out of the feed roller body through at least one opening defined therein,
- at least one moveable support coupled to the cutting blade and having a first end pivotally connected to the feed roller body and a second end;
- wherein as the feed roller rotates to pivot the at least one moveable support about the first end thereof and move the cutting blade at least partially through the at least one opening defined in the feed roller body and toward engagement with the sheet material;
- and
- a biasing assembly coupled to the feed roller and configured to one or more of:
- assist rotation of the feed roller;
- or
- facilitate movement of the cutting blade
- wherein the biasing assembly comprises one or more biasing members positioned within the chamber and extending at least partially along a rotational axis of the feed roller body.
A dispenser for dispensing a sheet material, comprising:
- a feed roller configured to engage and feed the sheet material from a supply of sheet material;
- a cutting assembly at least partially disposed within the feed roller, the cutting assembly comprising a cutting blade and a moveable support;
- wherein the moveable support comprises a first end pivotally connected to an interior surface of the feed roller and a second end adapted to move about a cam track defined along the feed roller such that the moveable support is pivoted about the first end thereof to move the cutting blade toward engagement with the sheet material;
- and
- a biasing assembly comprising at least one biasing member positioned within the feed roller and extending at least partially along a rotational axis of the feed roller, the at least one biasing member configured to assist rotation of the feed roller, to facilitate movement of the cutting blade through one or more openings formed through the feed roller for at least partially cutting or perforating a selected portion of the sheet material, or a combination thereof.
