Abstract
A web driving device including a web, a winding axis connected to a first end of the web and configured to rotate and wind the web about the winding axis in a winding direction, and a supplying axis connected to a second end of the web and configured to rotate. The web driving device further includes a driving device configured to drive the winding axis in the winding direction. The driving device is configured to prevent rotation of the winding axis when the driving device is in an inactive condition. The web driving device further advantageously includes an intermediate gear device engaged to the winding axis and configured to restrict rotation of the supplying axis when the winding axis stops rotating.
Claims16
A web driving device comprising:
- a web configured to scrub an object;
- a winding axis connected to a first end of the web, and configured to rotate and wind the web in a winding direction;
- a supplying axis connected to a second end of the web, and configured to supply a new part of the web and rotate in a supplying direction;
- a driving device configured to drive the winding axis in the winding direction;
- lock means for preventing the winding axis from rotating in a direction opposite to the winding direction;
- and
- restricting means for restricting rotation of the supplying axis when the winding axis stops rotating, wherein the restricting means is driven by the driving device when the driving device is active, the restricting means is stopped when the driving device is inactive, and the restricting means allows relative rotation between the supplying axis and the winding axis in a first direction and prevents relative rotation between the supplying axis and the winding axis in a second direction opposite the first direction.
A web driving device comprising:
- a web configured to scrub an object;
- a winding axis connected to a first end of the web, and configured to rotate and wind the web in a winding direction;
- a supplying axis connected to a second end of the web, and configured to supply a new part of the web and rotate in a supplying direction;
- a driving device configured to drive the winding axis in the winding direction;
- lock means for preventing the winding axis from rotating in a direction opposite to the winding direction;
- and
- restricting means for restricting rotation of the supplying axis when the winding axis stops rotating, wherein the restricting means is driven by the driving device when the driving device is active and the restricting means is stopped when the driving device is inactive,
- further comprising a first protrusion rotatably equipped in the supplying axis, wherein;
- the restricting means has a restricting gear configured to rotate in a direction opposite to the supplying direction and a second protrusion configured to rotate with the restricting gear;
- and
- the supplying axis is restricted from rotating when the first protrusion is engaged with the second protrusion in an inactive condition of the driving device.
A web driving device comprising:
- a web;
- a winding axis connected to a first end of the web, and configured to rotate and wind the web about the winding axis in a winding direction;
- a supplying axis connected to a second end of the web, and configured to rotate in a supplying direction;
- a driving device configured to drive the winding axis in the winding direction, the driving device being configured to prevent rotation of the winding axis when the driving device is in an inactive condition;
- and
- an intermediate gear device engaged to the winding axis, and configured to allow relative rotation between the supplying axis and the winding axis in a first direction and to prevent relative rotation between the supplying axis and the winding axis in a second direction opposite the first direction in order to restrict rotation of the supplying axis in the supplying direction when the winding axis stops rotating.
A web driving device comprising:
- a web;
- a winding axis connected to a first end of the web, and configured to rotate and wind the web about the winding axis in a winding direction;
- a supplying axis connected to a second end of the web, and configured to rotate;
- a driving device configured to drive the winding axis in the winding direction, the driving device being configured to prevent rotation of the winding axis when the driving device is in an inactive condition;
- and
- an intermediate gear device engaged to the winding axis, and configured to restrict rotation of the supplying axis when the winding axis stops rotating, wherein:
- the supplying axis includes a first protrusion fixed thereto;
- the intermediate gear device includes a second protrusion fixed thereto;
- and
- the second protrusion is configured to engage the first protrusion to prevent the supplying axis from rotating in at least one direction when the driving device is in the inactive condition.
A web driving device comprising:
- a web;
- a winding axis connected to a first end of the web, and configured to rotate and wind the web about the winding axis in a winding direction;
- a supplying axis connected to a second end of the web, and configured to rotate;
- a driving device configured to drive the winding axis in the winding direction, the driving device being configured to prevent rotation of the winding axis when the driving device is in an inactive condition;
- and
- an intermediate gear device engaged to the winding axis, and configured to restrict rotation of the supplying axis when the winding axis stops rotating,
- wherein the supplying axis includes a one-way gear assembly having a one-way clutch configured to engage the supplying axis to the intermediate gear device and prevent the supplying axis from rotating in at least one direction when the driving device is in the inactive condition.
A web driving device comprising:
- a web;
- a winding axis connected to a first end of the web, and configured to rotate and wind the web about the winding axis in a winding direction;
- a supplying axis connected to a second end of the web, and configured to rotate;
- a driving device configured to drive the winding axis in the winding direction, the driving device being configured to prevent rotation of the winding axis when the driving device is in an inactive condition;
- and
- an intermediate gear device engaged to the winding axis, and configured to restrict rotation of the supplying axis when the winding axis stops rotating, wherein;
- the intermediate gear device includes a first portion engaged to the supplying axis and having a first tooth;
- the intermediate gear device includes a second portion engaged to the winding axis and having a second tooth;
- and
- the second tooth is configured to engage the first tooth to prevent the supplying axis from rotating in at least one direction when the driving device is in the inactive condition.
