4 Claims. (Cl. 242157) ABSTRACT OF THE DISCLOSURE A reeling machine having a traverse guide for directing the wound material onto the reel, which traverse guide urges the reeled material toward the axis of the reel but may be disconnected by a toggle action to stop the reel should some obstruction be encountered.

This application is a division of my application, Ser. No. 362,353, filed Apr. 24, 1964, now abandoned.

When it is desired to provide a self-supporting coil of material such as hose, a special type of traverse has to be employed in order that that coil may be self-supporting. Heretofore, the provision of the special type of traverse has been largely hand done or requires a manual operation which results in considerable manual labor and a slower production of the finished product than if some automatic means or mechanical means were utilized.

One of the objects of this invention is to provide a traverse motion which will mechanically provide a selfsupporting coil with little or no need for manual control.

Another object of this invention is to provide a means for stopping the reeling machine upon the work reaching a predetermined diameter.

.Another object of the invention is to stop the reeling machine should a kink or bunch occur of a predetermined abnormal size.

With these and other objects in view, the invention con sists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

FIG. 1 is an elevation largely diagrammatic showing the reel and driving mechanism for the traverse guide of the reel;

FIG. 2 is an end view of the reel and showing the traverse guide in one position of operation for guiding the work on the reel; and

FIG. 3 is a view similar to FIG. 2 with the reel omitted but illustrating the guide in an operative position.

In proceeding with this invention, I utilize a power source or motor for driving the reel upon which the work is to be wound and also from this power source and in time with the driving of the reel, I provide an intermittent drive for directing the traverse of the work on the reel. The traverse is of the type which will direct the work onto the reel for at least three quarters of the reels revolution so that the work will be in substantially a single plane and then quickly traverse during the remaining quarter of a revolution to direct the work in a coil which will be in a plane substantially parallel to the plane of the first coil mentioned. Further the traverse is such that upon the return wind of the work after providing the first layer, the work will lay in one less coil along the second layer, thus enabling the circular diameter of the work to enter the grooves provided by the coils in the first layer of Work. The third layer of work will be the same number of coils as the first layer and the fourth the same as the second, and so on, that is the number of "ice coils will alternate between successive layers. In order to accomplish this, I have utilized the intermittent drive to advance the traverse guide through a cam which will move the guide the desired increment to provide the number of coils in each layer. Thus, the cam will control the first layer and the second layer before providing a repeat. I have also provided, through an arrangement by which the pivot for a lever which throws or moves the traverse guide from the cam, an arrangement so that by changing this pivot, the diameter of the work which is being reeled may be compensated for so that without changing the cam or its drive, an adjustment may be made for accommodating an infinite variation in diameters of work which is being operated upon.

With reference to the drawings, the reel is designated generally 10 having heads 11 and a barrel 12, along any portion of which the work may be Wound.

Power is supplied to drive the reel by a motor 15 driving shaft 16 through belt 17. The shaft 16 drives an indexing mechanism 18 through chain 19 and shaft 26) while a chain 21 driven from shaft 2%) drives the shaft 14 on which the reel 10 is mounted. The indexing mechanism provides an intermittent motion or intermittent drive to its output gear 25 so that this gear will have a fraction of a revolution for each revolution of the reel and may take the form shown in United States Patent No. 2,999,311. The output 25 is used to drive the traversing mechanism.

The traversing guide comprises a grooved pulley member having a rather deep groove 31 therein which is rotatably mounted upon a rod 32 designed to move axially of the reel and is in fairly close adjacency to the reel 10' as seen in FIG. 2 so as to direct cylindrical work or the like 33 onto the barrel 12 of the reel. This rod 32 which is guided to reciprocate parallel to the axis of the reel is operated by a lever 35 having a yoke 27 which is rockably secured to a collar 28 adjustably fixed to the rod as at 29. This lever 35 is pivoted on a support 36 by an adjustably mounted pivot 37. Thus, this pivot 37 may be located closer to or further from the rod 32. The other and lower end of the lever 35 is provided with a slot 42 and is connected to a rod 43 by means of a pin extending into this slot, this rod 43 being arranged to slidably reciprocate or be guided in a path parallel to the movement of rod 32. It will be apparent that as rod 43 moves in one direction, the rod 32 will be moved in the opposite direction, and the amount of the movement of the rod 32 will be dependent upon the location or" the pivot 37. Thus, if the pivot is located an equal distance between the axes of the two rods 32 and 43, equal movement will be transmitted by movement of the rod 43 to the rod 32, whereas if the pivot is closer to the rod 43 than it is to the rod 32, a greater movement will be afforded the rod 32 for an equal increment of movement of the rod 43. By this arrangement the amount of throw given to the traversing guide may be adjusted as to the varying diameters of the work which is to be reeled, and the adjustment may be infinite in amount due to this arrangement.

Movement of the rod 43 in its guides 44 and 45 is accomplished by means of a cam follower 46 engaging a groove 47 in a cam 48. This cam is mounted to rotate about an axis 49 and has fixed to it a gear 50. The gear and the cam 48 together provide a change mechanism which alone need be changed for controlling the type of wind which is to be provided for the work on the reel.

The gear 50 is also mounted upon the axis 49 of the cam, and this gear is driven from the intermittently op erated output gear 25 through an idler 51 which is mounted upon an arm (not shown) so that it may be swung toward and from the gear 50 about the pivot or axis of the intermittently operated gear 25. Thus, the gear 50 and its cam may be removed and replaced by a different cam and gear, and the idler swung back into position with the gear 50 for operation.

The intermittent drive is such that the shift of position of the work from one plane to another will be performed engaging during one quarter of the revolution of the reel by reaand so on, each time there being a transfer from one coil to the next coil in one quarter revolution as indicated in FIG. 5, thus providing a stable package. In the above example of a 6-5 wind, it will be apparent that the cam 48 intermittently revolves of a revolution for each revolution of the reel 10. It follows therefore that the gears 25, 5t), 51 must provide this relative rotation assuming a 1:1 ratio of the main chain couplings 19, 21.

The traverse guide 30 has associated with it a feeler' designated generally 59 (FIG. 3) comprising a radially extending portion 60 and a package engaging portion 61 extending generally at right angles thereto. Thus, when in operative position, the portion 61 will engage the package at 61a (FIG. 2). This portion 61a has a concave groove in it so as to straddle the circular diameter of the work which it engages. Thus, as the package builds up, this feeler will swing on its pivot about the axis of the rod 32 and eventually move into an up position such as shown in FIG. 3.

The work is urged into the groove of guide pulley 30 by a retaining roller 62 (FIG. 2) having a concave surface to assist in guiding and urging the work 33 into the groove 31 of theguide pulley 30, and this retainer 62 .is pivotally supported on an arm 63 which is pivoted as at 64 on the part 60 of the feeler. A resilient means designated generally 65 serves as a toggle to urge this retainer in one position or the other. This resilient means 65 is pivoted on an offset 66 from the rod 32 and acts between a point 67 on this offset and the arm- 63 adjacent the retainer 62 so that when the retainer is in the position shown in FIG. 2, this resilient means will be above a line between the pivot 64 and the pivot of the retainer 62 and thus will act downwardly, tending to move the retainer toward the grooved traversing guide 30. In this operating position the arm 63 will be in such a position that the resilient leaf spring 70 will press upon the contact controlling arm 71 of a switch 72 so as to maintain the circuit to the electric motor in a manner well known to those skilled in the art.

However, should some kink in the hose occur which will raise the retainer 62 slightly, the contact will then be broken by the raising of the arm in the direction of the arrow-73, and the machine will stop. If this kink is of a minor extent, it may naturally straighten out and the machine Will move back into operative position by reason of the resilient means 65. However, if the kink is of substantial extent and it cannot straighten itself out by mere intermittent stopping of the machine, then the kink will force the retainer 62 outwardly to a point where the resilient means 65 will act on the other side of a line hetween pivot 64 and the retainer, moving it to the raised position shown in FIG. 3 which will permit the arm 71 to raise and the switch to break the circuit to the motor 15 and stop the machine. It will also be apparent that if an enlargement at the end of the work comes in contact with the retainer 62, this same action will occur to stop the motion, or should the work be reeled to a point where the feeler 61 is raised to the location shown in FIG. 3, the machine will also be stopped by reason of the toggle action and the resilient means above referred to.
