Abstract

Apparatus for marking a hot coil of strip including a ram movable toward and away from the coil. The ram pivotally supports a pair of spaced yokes having rollers at the ends of the arms of the yokes for engaging the coil at points spaced about the periphery thereof. A marking device is carried by the arms so that it is positioned as desired with respect to the coil.

R a 7 1 U m 4 m l B m m PATENTEU JAN 26 1971 INVENTOI? ALFRED TEPL/TZ A florn ay APFAKRATEJS FOR MARKING A COlL F STRIP This invention relates to coil-marking apparatus and more particularly to such apparatus for marking hot steel coils leaving a hot strip mill.

The most common way of doing this is by manually writing" on the coil with hot chalk," a waxy crayon that melts at high temperatures and leaves a permanent mark. This method is unsatisfactory because of the adverse environment for the person who does the marking, i.e.'the high temperatures and attendant health hazards which induce worker fatigue, carelessness and erroneous markings. Labor costs are also high with this method.

It is therefore an object of my invention to provide marking apparatus which permits reliable marking from a remotely originated SignaL. thus eliminating the environmental influences and allowing a reduction 'of labor costs.

Another object is to provide such apparatus which applies the marking uniformly and accurately.

These and other objects will be more apparent after referring to the following specification and attached drawings, in which:

The single FIG. is an isometric view of the apparatus of my invention.

Referring more particularly to the drawing, reference numeral 2 indicates a conveyor on which is supported a hot coil of strip C with its axis vertical. Spaced from the conveyor 2 is a base or pedestal 4 having a horizontal opening 6 therethrough which acts as a guide for slidably receiving a ram 8. The ram 8 is reciprocated by means of a fluid motor 10 supported by base 4 with its piston rod 12 connected to the ram 8. A control valve 34 of conventional type controls operation of the motor 10. This may be accomplished manually or by movement of coil C contacting a switch (not shown) when it reaches a position in front of the ram 8. A pivot pin 18 is secured to the outer end of ram 8 with its axis parallel to the axis of coil C. Aligned top and bottom bifurcated yokes 20 and 22 are mounted on pin 18 for rotation about the axis thereof. Vertical shafts 2d extend between corresponding arms of the yokes 20 and 22 at the outer ends of the anus and support rotatable rollers 26. Marking heads 28 are mounted on the arms of the yokes 20 and 22 in any suitable manner. They may be stationary or may be adjustably mounted, as shown, by means of slots 30 in the arms of the yokes and held in place by means of set screws 32 passing through the slots. One or more marking heads 23 may be provided as required. The particular type of marking head used forms no part of the present invention, but it is preferred to use an ink applicator such as shown in the copending application of Francis et al., Ser. No. 705,734 filed Feb. 15, 1968.

In operation, when a coil C arrives at the marking station on conveyor 2, the ram 8 will be in retracted position. At this time the valve 14 will be operated by the workman to cause fluid to flow to the left side of motor 10, thus moving the ram 8 forwardly. When the coil C is not absolutely centered one of the rollers 26 will first contact the coil C and continued movement of the ram will cause the yokes 20 and 22 to pivot about the axis of pivot pin 18 and thus bring the second roller in contact with the coil C. This positions the marking heads 28 in the preset position for optimum marking, which for most marking operations is such that the spray axis of the marking device is normal to the surface to be marked. This angle may be varied if desired. At this time the marking heads are activated to mark the coil. Following this, the valve 14 is actuated to supply fluid to the forwardend of motor 10, thus retracting ram 8 to its original position.

While one embodiment of my invention has been shown and described, it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.

I claim:

1. Apparatus for marking a coil of strip comprising a support for said coil, a ram movable in a generally radial plane including the axis of said coil toward and away from the axis of said supported coil, a ivoted member mounted on the end of said ram ad acent sat coil with its pivot axis parallel to the axis of said supported coil, a marking device mounted on said pivoted member, and spaced means mounted on said member at opposite sides of said generally radial plane, said pivoted member being freely pivotal about its axis to permit engagement of the coil at points spaced about the periphery thereof to move said marking device into position to mark said coil.

2. Apparatus for marking a coil of strip according to claim 1 in which the coil support is a conveyor which supports said coil with its axis vertical.

3. Apparatus for marking a coil of strip according to claim 2 in which said pivoted member includes aligned top and bottom bifurcated yokes with the apex of each yoke at the axis of said pivoted member and the two an'ns thereof extending toward said conveyor; and said spaced means includes vertical rollers extending between the aligned arms of the yokes at the outer end thereof, said rollers adapted to engage said coil; and said marking device is mounted on the arms of said yokes.

4. Apparatus for marking a coil of strip according to claim 3 including a base having a horizontal guide for slidably receiving said ram, and a fluid motor supported on said base for moving said ram toward and away from said coil on said support.

Claims (4)

1. Apparatus for marking a coil of strip comprising a support for said coil, a ram movable in a generally radial plane including the axis of said coil toward and away from the axis of said supported coil, a pivoted member mounted on the end of said ram adjacent said coil with its pivot axis parallel to the axis of said supported coil, a marking device mounted on said pivoted member, and spaced means mounted on said member at opposite sides of said generally radial plane, said pivoted member being freely pivotal about its axis to permit engagement of the coil at points spaced about the periphery thereof to move said marking device into position to mark said coil.
2. Apparatus for marking a coil of strip according to claim 1 in which the coil support is a conveyor which supports said coil with its axis vertical.
3. Apparatus for marking a coil of strip according to claim 2 in which said pivoted member includes aligned top and bottom bifurcated yokes with the apex of each yoke at the axis of said pivoted member and the two arms thereof extending toward said conveyor; and said spaced means includes vertical rollers extending between the aligned arms of the yokes at the outer end thereof, said rollers adapted to engage said coil; and said marking device is mounted on the arms of said yokes.
4. Apparatus for marking a coil of strip according to claim 3 including a base having a horizontal guide for slidably receiving said ram, and a fluid motor supported on said base for moving said ram toward and away from said coil on said support.
