6 Claims.

This invention relates to the coiling of continuous strip metal, and particularly to apparatus or means for determining the time required for coiling the same.

It is the general object of the present invention to provide an improved apparatus or means whereby the time that it is required to coil strip metal on a take-up block after it has been rolled or otherwise processed can be quickly and conveniently ascertained.

It isanother object of this invention to provide an improved apparatus or means of determining the time for coiling continuous strip metal which is not only simple and inexpensive in its construction and use, but an apparatus which can be easily incorporated with existing equipment at a minimum expense.

It is a further object of the invention to provide an improved electrically controlled appae ratus or means for determining the time for coiling continuous strip metal which is controlled by the strip itself and is substantially fool-proof, and yet an apparatus which accurately records the coiling time.

Various other objects and advantages of this invention will be more apparent in the course of the following specification and will be particularly pointed out in the appended claims.

In the accompanying drawing, there'is shown for the purpose of illustration, one embodiment which our invention may assume in practice.

In the drawing:

Figure 1 is a plan view of rolling mill and coiling device showing the improved timing apparatus of our invention incorporated therewith;

Figure 2 is a side elevation of Figure 1;

Figure 3 is an enlarged section taken on the line I[IIH of Figure 1;

Figure 4 is a section taken on the line IV-IV of Figure 3; and

Figure 5 is a diagrammatical view of the wiring arrangement.

- Referring more particularly to the drawing, the

improved apparatus of our invention is shown incorporated with a conventional mechanism for coiling strip metal which consists generally of a base or frame 2 having a cylindrical metallic coiling block 3 rotatably mounted thereon. The block 3 is adapted to coil continuous strip metal as it is delivered thereto and is adapted to be rotated by any suitable means (not shown). There is arranged forwardly of the base or frame 2 and the coiling block 3, a cold rolling mill, and there is shown in the present instance for the purpose of illustration only the work rolls 4 thereof.

According to the present invention, there is disposed in a laterally extending groove or slot 5 arranged in the periphery of the cylindrical block 3, a metallic insert contacting member S having a projecting portion or' segment I arranged therewith preferably on the inner end thereof. The insert member 6 extends substantially through the width of the block 3 preferably flush with the outer face thereof, and is insulated therefrom by means of an insulating material 8 which is preferably made of fiber, rubber or any other suitable material and which is positioned between the insert member and the walls of the groove 5 in the block 3.

There is suitably arranged preferably in the vicinity of the coiling mechanism, an electrically controlled recording instrument 9. This instrument may be any of the known conventional types, but it is preferable that an Esterline-Angus graphic instrument be provided. Such an instrument consists generally of a rotatable cylinder which is adapted to hold a paper chart and which is driven at a constant speed by a clock mechanism. There is provided a pen which rests on the chart and which makes a continuous straight line on the same as the cylinder revolves, as long as the pen is not moved. The pen is controlled by electromagnets and when the same are energized, the pen is caused to be moved so as to make a mark on the chart substantially perpendiculartothe straight continuous line, and it is returned to its normal position usually by means of a spring. Therefore, each electric impulse which energizes the electromagnets will be recorded on the chart of the instrument. The instrument, of course, is suitably connected to a suitable source of power (not shown) to operate the same.

One side of the instrument is connected to the base or frame 2 of the coiling mechanism by means of the line Ill and the other side of the recording instrument is connected preferably to a contact finger l2 by means of line 13. The ,contact finger I2 is preferably mounted on an insulating block I which is suitably arranged preferably on the side of the frame 2 directly opposite the projecting portion or segment 1 carried by the insert member 5.

The improved apparatus of my invention functions in the following manner. The continuous strip of metal S is fed from the pay-off reel through and between the cold working rolls I and delivered to the coiling block 3. At the start of the coiling operation of any particular strip, the same is directed around the cylindrical coiling block 3 so as to make the first or inner convolution of the coil. It will thus be seen that this first convolution of the metallic strip contacts both the insert member 6 and the block 3 thereby completing one portion of an electric circuit therethrough. That is to say, an electric circuit is completed through the insert member 8, the first convolution of the strip S, the block 3, the frame 2 and the line 59, to the recording instrument 9. After the first convolution of the strip has been disposed around the block 3, the projecting portion 7 of the insert member 6 strikes or contacts the contact finger i2 upon each revolution of the block. Thus, it will be seen that when the projecting portion '1 strikes the contact finger E2, the other portion of the electric circuit is completed, namely through the contact finger l2 and the line E3, to the recording instrument ti, thereby energizing the electric magnets of the instrument which in turn move the pen once each revolution of the block. Thereafter, the time for completely coiling the strip of metal on'the block 3 can be readily ascertained upon inspection of the chart of the recording instrument. After the coiling of the strip has been completed, the coiled strip is removed from the block thereby breaking the circuit between the insert member 6 and the block 3. any further rotation of the block 3 will not be recorded by the recording instrument as there is then not a complete electric circuit.

The improved apparatus of our invention has been shown incorporated with coiling mechanism for coiling strip metal as it is delivered. from a.

cold rolling mill, but it will be understood that it may be used in connection with a coiling block for receiving and coiling the metal from any other machine or process during the manufacture of the strip. Also the improved apparatus of our invention may be incorporated with a coiling mechanism for coiling wire, rod, or other continuous length metallic materials.

While we have, in this application, specifically shown and described one embodiment of our invention, it will be understood that this embodiment is merely for the purpose of illustration and description, and that various other forms may be devised within the scope of the invention, as defined in the appended claims.
