Definitions
- This invention relates to a self inking roller of the type which can be used in conveyor line coders, hand printing rollers, printing presses and other related equipment.
- the general object of the present invention is to provide an improved form of inking roller having an internal reservoir for ink and having valve which can be easily actuated so as to effectively prevent flow of ink from the reservoir. Further, the object is to provide a self-inking roller having an internal reservoir which in preferred embodiments can be formed with a central bore right through the roller so that it can be mounted in a stable manner in a variety of different forms of equipment which are provided with spindles for receipt of printing rollers.
- a self-inking roller comprising a main body mounted for rotation on a spindle, a cylindrical porous member disposed on an external surface of said main body an ink reservoir within said main body an ink distribution path which enables ink to flow from said reservoir to said porous member characterized in that the ink roller includes valve means comprising an annular valve seat on said main body and an annular valve element and valve actuating means for moving the valve element relative to the valve seat for controlling the ink flow in said path.
- the main body includes a substantially cylindrically shaped section and there is further provided a tubular spindle mounting member having a bore therein for receiving the mounting spindle the tubular member being coaxial with the cylindrically shaped section and operatively connected thereto for rotation therewith.
- a tubular spindle mounting member having a bore therein for receiving the mounting spindle the tubular member being coaxial with the cylindrically shaped section and operatively connected thereto for rotation therewith.
- opposed end caps are provided at respective ends of the cylindrically shaped section.
- the self-inking roller may further include coupling means operatively connecting the valve actuating means to the valve element.
- the annular valve seat is disposed near one end of the main body and the coupling means includes a tubular member arranged coaxially with the spindle mounting member and said main body and arranged for axial movement relative to the main body to cause relative movement between the valve element and the valve seat.
- the actuating means comprises one of the end caps mounted for limited axial movement relative to the main body by rotation thereof relative to the spindle mounting member.
- the flow path may include a circumferential distribution channel at one end of the main body adjacent the valve means and a plurality of openings in the wall of the main body adjacent the distribution channel permitting ink to flow to the external surface of the main body.
- the coupling means comprises a cam element mounted between the spindle mounting member and the valve element.
- Figure 1 is an end view of one preferred embodiment of the ink roller of the invention
- Figure 2 is an axial sectional view of the roller shown in figure 1
- FIG. 3 is an exploded view of the roller shown in figures 1 and 2,
- Figure 4 is a sectional view taken along the line V-V in Figure 5 .
- Figure 5 is a sectional side elevation of another preferred embodiment of the ink roller of the invention.
- the illustrated inking roller comprises a central tubular member 2 the bore 4 of which receives in use a mounting spindle (not shown) for mounting the roller.
- the tubular member 2 extends within a cylindrical opening formed in a body portion 6.
- the body portion has a cylindrical wall 8 which serves as a support surface for a porous inking member 10.
- the interior of the main body portion 6 serves as a reservoir for ink.
- the body 6 is preferably fabricated from a number of components including an inner tubular member 12 which lies adjacent to the tubular member 2 an annular wall 14 which is connected to the tubular member 12 and a downwardly extending cylindrical member 16 the outer surface of which constitutes the supporting surface 8.
- the reservoir is closed by a movable annular disc 18 which is located adjacent to the end of the tubular member 12.
- the annular disc 18 has an oblique face 22 which serves as a valve element and bears against a complementary face 22 formed on the lower part of the cylindrical member 16, the face 22 serving as a valve seat.
- the cylindrical member 16 is formed with an ink distribution channel 24 near its lower end, the channel 24 having openings 26 which communicate with the interior of the member 16 beneath the annular disc 18. It will be appreciated that when there is a gap between the valve element 20 and valve seat 22 ink can flow from within the annular ink chamber within the tubular member 16 to the distribution channel 24.
- the tubular member 16 includes a number of axially extending ink distribution channels 28 which communicate with the circumferential channel 24 and permit flow of ink more or less uniformly to the interior surface of the porous member 10.
- the lower end of the body 16 is received within an annular end piece 30, the member 16 being provided with threads 32 which cooperate with complementary threads provided in a groove in the end piece 30.
- the end piece 30 seals against the tubular member 2 at a reduced diameter portion 34 thereof.
- a compression spring 37 surrounds the tubular member 2 and acts between the end piece 30 and the annular disc 18 and serves to bias the latter such that the surfaces 20 and 22 engage to thereby prevent flow of ink into the channel 24.
- tubular member 2 may be threaded at its end remote from threaded end 38 and adapted to co-operate with a centrally disposed threaded section on end piece 30.
- O-rings may be provided to seal the end piece and the tubular member and cylindrical member.
- the roller further includes an annular top end piece 36 which is threadably mounted on threads 38 formed on the upper end of the tubular member 2.
- the end piece 36 effectively forms a closure for the ink reservoir of the roller.
- the piece 36 is formed with an outer recessed face 40 which provides a seating for an outer O-ring 42 which bears against an adjacent shoulder 44 formed on the upper surface of the annular wall 14.
- An inner O-ring 46 is provided and it is seated in a groove 48 formed in the tubular member 2 and bears against a shoulder 50 formed adjacent to the inner bore of the end piece 36.
- the end piece 36 can be removed from the roller by rotating it so that it moves axially on the threads 38 provided on the tube 2. Once the end piece 36 has been removed, the ink reservoir can be filled by pouring ink onto the annular wall 14 so that it will run through filling openings 52 provided therein. The end piece 36 may then be replaced and the O-rings 42 and 46 will prevent ink leakage. It will be noted that the end piece 36 includes an annular projection 54 which lies adjacent to the upper surface of the annular portion 14. The arrangement is such that the end portion 36 can be tightened so that the projection 54 will engage and resiliently deflect that member 14 downwardly so that it in turn will cause the surfaces 20 and 22 to separate thereby enabling ink to flow from the reservoir through the openings 26 and into the channels 24 and 28.
- the valve constituted by the surfaces 20 and 22 is operable more or less independently of the orientation of the roller.
- the lower end piece 30 can be removed from the body 16 by rotating it so that it moves on the threads 32 provided on the lower end of the body. Once the end piece 30 has been removed, the porous member 10 can be removed by downward axial movement so that it can be serviced and/or replaced. This is also seen as a useful advantage.
- the member 10 is preferably formed in the annular wall 14 and end piece 30 respectively so as to assist in holding it in position on the surface 8 between the wall 14 and end piece 3.
- the inking roller is essentially the same as that shown in figures 1 to 3 except for the arrangement of the valve means and the flow path.
- this roller comprises a central tubular member 2 the bore 4 of which in use receives a mounting spindle.
- a main body 6 having a cylindrical wall 8 and a porous inking member 10.
- valve means comprises a plurality of valve seats 61 around openings 64 the valve seats 61 being axially disposed along the wall of the main body 6.
- the valve member comprises a tubular section 62 with a plurality of valve stems 63 projecting therefrom each being adapted to co-operate with respective valve seat 61.
- the valve member is inhibited from relative rotation with respect to the main body 6.
- the coupling member comprises a cam 65 rotatably mounted between spindle mounting tube 2 and the tubular section 62 of the valve member.
- the cam 65 has a slot 67 therein which is engaged by pin 68 when the cap 36 defining the actuating means has been screwed in sufficiently.
- a pressure relief valve 71 provides communication between the ink reservoir and atmosphere and is operative should a vacuum be created in the reservoir as a result of the discharge of ink therefrom.
- the pressure relief valve may be of any suitable form.
