Coating roller and coating apparatus
First Claim
1. coating apparatus comprising:
- a coating roller rotatably supported at one end by a support which forms part of a holder,a coating supplying apparatus having;
a coating feed mechanism for discharging a coating material from a coating tank,a control apparatus for controlling operation of the coating feed mechanism, anda hose for connecting the coating roller and the coating supplying apparatus,wherein said control apparatus detects a number of revolutions of the roller and actuates the coating feed mechanism according to the number of revolutions detected so that coating material is supplied to the roller at a coating flow rate corresponding to the number of revolutions of the roller, and further wherein the rotational direction of the roller is discriminated so that when the roller rotates in a predetermined direction, the coating feed mechanism is not actuated and the coating material is not supplied to the roller.

Abstract
In order to supply a coating to a roller, a coating supplying groove is provided along only one side of a core which is connected to an end of a support so as to act as a shaft of a roller. A coating reservoir between the roller and the core is located to one side of the core. To permit engagement and disengagement between the support and the core, an elastic member is mounted within a coating flowing hole of the core, while an inserting groove and a stopping groove are provided in the inner peripheral surface of the coating flowing hole of the core. To automatically stop and start the supply of coating to the coating roller, and to adjust the flow rate, the number of revolutions of the roller are detected and used to actuate the coating feed mechanism to supply coating at a flow rate corresponding to the number of revolutions and or direction of rotation of the roller.

7. A coating roller comprising:
-
a support formed with a stopping projection on a roller supporting portion thereof, a core detachably connected to an end of the support to constitute a shaft of the roller, said roller being disposed on said core; said core comprising; a core body having; a coating supplying groove formed axially along one side of said core body, an axially extending coating flowing hole formed in a surface of said core body which is proximal said support, and a coating outflow port which is communicated with the coating supplying groove and which is provided in one of a middle portion and a downstream end of the coating flowing hole, a fitting body inserted in the coating hole having an inserting groove capable of engaging and guiding the stopping projection at the support, said inserting groove being provided in the inner surface and, a stopping groove which is provided at the inner end of the inserting groove, a spring mounted within the coating flowing hole, so that when the stopping projection of the support arrives at the stopping groove after passing through the inserting groove, the stopping projection is elastically engaged with the stopping groove under the influence of repulsion produced by the spring, an adjusting plate provided with a plurality of axially spaced pores, said adjusting plate being disposed within said coating supplying groove, wherein said core further comprises a closing body, the closing body having an inner surface in which stopping groove portions are formed, wherein said core body has an end on which stopping projections are formed, and wherein the adjusting plate is held between said core body and said closing body when the stopping projections of said core body are stopped at the stopping groove portions of said closing body.
