This invention relates to a wire guiding device and more particularly :to. a. guiding device for usewith a. wire, cord, rope and the like reeling mechanism, although: not necessarily so limited.

In connection with prior art wire reeling devices. and'the like. where it is found desirable. to uniformly wind a wire, a. wire guiding mechanism is used which requires adjustment whenever there is a. change in the size of the wire or a changein the width of the spool- An object of this invention is to provideia wire guiding device that automatically feeds the. wire to a place, where it is to be used in suchamanher that: the wire is uniformly laid in position without making changes or adjustments when shifting from one type of wire or one type of spool to another, as the case may be.

Another object of this invention is to provide a wire guiding device that is electrically controlled and. fluid driven, the electrical controls being used to control the quantity and the direction of the fluid flow.

Another object of this invention is to provide a feeler' or a control arm that isv responsive: to the angular position of the wire from the con.- trol mechanism to the place Where the wire. is used for use in determining the rate of speed and the direction of movement of the wire guiding mechanism.

Other objects and advantagesres-ide in theconstructionof parts, the combination thereof and the mode of operation, as will become more apparent from'the following description.

Referring to the drawings, Figure 1 is a perspective-view of the wire guiding mechanism used in association with a coil winding device, only a portion of the coil winding device being shown.

Figure 2 is a schematic view illustrating the circuit arrangement and the fluid passages, together with the controls therefor.

Figure 3 is a fragmentary'cross sectional view taken substantially on the line 3--3 of Figure 1.

In thedrawings, the reference character l0 indicates a wire fed from a. suitable source of supply, not shown, to a spool l2 that is being rotated by means of a coil winding or reeling mechanism l4, shown schematically. In laying the wire [0 upon the spooLthe wire is preferably laid in uniformly spaced convolutions l6, laid in contact with each other. If the who has a reasonable thickness or diameter it has a tendency, if properly fed, to-be wound in equally spaced convolutions.

A wire guiding mechanism hasbeen provided Cir for positioning the wire on the coil or spool. This wire guiding mechanism includes means for feed.- ing the wire in one direction or the other at the approximate speed required to lay the wires; in proper position on the spool. In addition thereto, this wire guiding. mechanism is provided with a control mechanism thatmay temporarily accel erate the movement or the wire guiding. mechanism by increasing the. speed thereof,, or. in the 2 event that the. wire has been, fed too rapidly;v it

will temporarily reverse. the direction of movement of the wire, guiding, mechanism until the wire. guiding mechanism. has been properly DQSi" tioned with respect to the demand on the; spool.

When one. layer of Wire hasbeen, laid on the spool, the. direction of movement of. the: wire guiding mechanism is automatically reversed. the wire guiding mechanismv being reversed in re sponse to the angular position of the wire. ex.- tendin from the wirev uiding, mechanism. to the spool. Immediately upon the reversal of the direction of movement of the wire guiding mechanism, the wire guiding mechanism travels at what might be referred to as high, speed. until the wire guiding mechanism is properly aligned with the wire fed, to the. spool, at which time the wire guiding mechanism automatically reverts to a slow speed, the approximate speed. required to properly lay the wire in. position, In the event the slow speed movement of the wire guiding mechanism is too slow, theguidingmechs anism is, automatically shifted. to. a high. speed movement untilit is. again properly aligned. II the slow speed movement of the wire guiding mechanism advancesv it. too' rapidly, the. direction of movement of the wire guiding mechanism is reversed. temporarilmthen re-reversed, when the guiding mechanism is, properly aligned. These operations. are. repeated until the. spool is com.- pletely wound,v at which time the coil. winding or reeling mechanism; l4 automatically stops the reeling operation, as will become. more apparent from the description that follows;

The. wire. guiding mechanism includes. an idler 26. rotatably mounted uponv a. bracket 22: fixedly mounted upon the end of a. piston rod 24 connected to the piston. 26,. as best seen in Figure 2; mounted in a cylinder 23. The bracket. 22.111.- cludes an arm portion 30 supporting a switch. box

7 32 and a pivotally mounted rocker arm 34: pro.-

vided with an elongated eye 36 through which the wire Hi extends. The. arm portion 3.0; is provided with a pair of stops 38. and 46 limiting the oscillatory movement of. the rocker arm. 34. This rocker arm 34 is. mountedin an. opening or aperture in the arm portion 30. The portion 34a extending through the arm portion 30 supports a switch-actuating lever 42 mounted between a pair of switch levers 44 and 46 connected to suitable switches in the

switch boxes

48 and 50 respectively.

In Figure 2 the switch-actuating lever 42 has been shown schematically as connected to a switch lever 60 having a pair of

switch contacts

62 and 64 adapted to engage fixed contacts 66 and 68. This has been shown to schematically illustrate the operation of the electrical control. When the wire In actuates the rocker arm 34 towards the left, as viewed in Figure 2, the switch contacts 64 and 68 close the circuit through a pair of relays I and 12 energized from the lines L1 and L2. When the relays I0 and I2 are energized, a valve member I4, connected to the armature 16 of the relay 1'0, is actuated into the full line position shown in Figure 2, so as to connect the portion of the cylinder to the left of the piston 26 through a port 80 to the exhaust passage 82 and the portion of the cylinder to the right of the piston 26 through a port 84 to the intake conduit 66 connected to a source of fluid such as air under pressure or a hydraulic fluid, as the case may be. At the same time, the relay 12 actuates an armature 90 connected to a valve member 92 opening a by-pass passage 94, permitting the fluid to the left of the piston 25 to escape at a very rapid rate, thereby permitting the piston 26 to travel at a high speed towards the left, as viewed in Figure 2, thereby actuating the guide unit including the idler 23 at a high rate of speed towards the left, as viewed in Figures l and 2, until the wire I0 moves the rocker arm 34 to a central or neutral position, so as to disconnect the contacts 04 and 08 and thereby de-energize the relays I0 and 12. By tie-energizing the relay I0, the valve member T4 remains in the position shown in Figure 2. By de-energizing the relay 12, the armature 90 is springurged to the right, as viewed in Figure 2, to close the passage 94, thereby reducing the rate at which the fluid is exhausted from the left of the piston 26, causing the piston to travel at a slower speed, which will be referred to as slow speed. This slow speed may be adjusted by adjusting the needle valve or metering screw 96, disclosed as a set screw, opening or closing the exhaust port 82, to thereby control the rate of fluid discharge.

In the event the wire guide unit including the idler 20 should travel at too rapid a speed, the wire I0 would actuate the rocker arm 34 towards the right, thereby actuating the switch contact 62 into contact with the fixed contact 66. Upon the switch contact 52 moving into contact with the fixed switch contact 66, the relays I00 and I02 are energized. The relay I00 exerts a pull upon the armature I04, so as to actuate the valve member I4 from the full line position shown in Figure 2 into the dot dash position. This results in the port 80 being moved into registry with an intake passage I06 and the port 84 being moved into registry with an exhaust port I08.

The relay I02, upon being energized, opens valve member IIO communicating with the exhaust port I08. When the valve members have been adjusted into this position, the fluid used in actuating the piston 26 is then applied to the left of this piston and the compartment to the right of the piston is connected to the exhaust port, causing the piston rod 24 to reverse the movement of the carriage 29 supporting the arm portion 30. The carriage 29 is then caused to travel at high speed towards the right, as viewed in Figure 2, that is, in the reverse direction to that described above. The carriage 29 continues to travel at high speed to the right until the wire I0 aligns the pivotally mounted rocker member 34, so as to disconnect the switch contact 62 from the fixed contact 66. This permits the valve I I0 to close by means of a spring, not shown, thereby reducing the size of the effective exhaust port to the size of the exhaust passage Il2 controlled by the adjustment of the needle valve or metering screw I I4. The valve member 74 remains in this position, causing the carriage 29 to travel at slow speed. The rate of travel of the slow speed is controlled by adjusting the metering screw 96 or II4, as the case may be.

The rate of travel of the carriage at slow speed is preferably slightly less than the rate at which the coil is being wound, so that intermittently the carriage will be advanced to high speed until it catches up with the winding operation. When it comes to the end of a layer of convolutions on a spool, the flanges I2a or I2b, as the case may be, arrest the continued winding of the convolutions in a layer. The carriage proceeds to travel in the same direction until the rocker arm 34 closes the switch contact 62 with either the fixed

switch contact

64 or 66, as the case may be, to actuate the valve member I4 into the reverse position. This causes the carriage 29 to first travel at a high speed in the opposite direction until the carriage is directly in line with the winding operation, at which time the carriage travels at low speed, which again is preferably slower than the rate of travel of the laying of the convolutions. When the carriage is misaligned, the contact 62 is again actuated in contact with the fixed switch contact, to energize the relays so as to increase the effective exhaust area of the exhaust port then in use to cause the carriage to travel at a high speed until it catches up with the wire being wound. These operations continue until the winding operation of the coil is completed. If, for example, eight convolutions are found in each layer and there are five layers to a coil, the coil winding machine is preferably set so that as soon as the spool being wound has been rotated through 40 revolutions, the rotation of the spool is arrested.

Instead of mounting a new spool, several spools aligned axially, may be used, as clearly shown in Figure l, in which event the wire is moved across the flange In to start the winding of the spool I20, which is then wound in the same manner, the coil winding machine automatically stopping the rotation of the spool when a predetermined number of convolutions have been wound upon the spool forming the core of a coil. This is made possible by using a sufliciently long cylinder permitting the piston to operate through various positions in the cylinder.

It can readily be seen that it is not necessary to in any manner adjust the operation of the wire guiding mechanism disclosed herein if another size of spool, either differing in width or differing in diameter, is being wound. In the event the diameter of the wire is either very materially decreased or increased, it may be found necessary to adjust the metering screws 96 and H4, so as to change the rate of the slow speed travel of the carriage guiding the wire to the spool.

Suitable stops I30 have been shown schematically in Figure 2 for limiting the movement of the valve member 14 in either direction. In actual accepts usage the valve membermaybe so designed that its movement is limited within the casing or the chest housing the same.

Instead of mounting the relays upon opposite ends of the cylinder 28, the relays may be mounted upon a support I32 shown in Figure 1, the relays being energized by means of electric leads forming a cable Hi4 connected to an outlet box I36. A cable I43 carries the leads from the switch boxes- 48- and 50 to the respective relays. The cylinder 28, together with the parts supported thereon, is mounted upon a bracket I50 provided with an apertured arm I52 receiving a guide rod I 54 connected tothe arm portion 30.

Although the device has been described in connection with formingcoils of wire, the device could be equally as well used with a device for reeling rope, cord, twine and other continuous length members, and, for that matter, it could be used in actuating a carriage to and fro in response to the angular direction for which there is a demand for the material to be guided.

Although the preferred embodiment of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
