. This invention relates to a reelfor supporting coiled wire stool; and more particularly to a stock supporting reel including power means arranged to uncoil the stock and advance the stock toward a machine using the same at a rate corresponding to the requirements of the machine.
in a high rate of unwinding of the coiled stock. Another improvement in this art relates to the use of much larger and heavier coils of wire.
stock so as to reduce the frequency of shutting down the machine for starting a new coilof stock. The increase in the speed of unwinding and the use of larger coils has introduced certain disadvantages particularly where the speed and rate of feed of the machine using the stock is subject to variations. It will be appreciated that when a machine, such as a nail machine, is operating at a rate of 1200 nails per minute and is unwinding from a heavy coil of wire stock the rotating stock coil has considerable inertia and when the speed and rate of feed of the machine using the stock is reduced the stock coil tends to continue to turn and unwind the stool: with the result that the excess unwound stock 'may cause tangling of the stock. A further disadvantage has developed in connection with. the larger coils in that it is necessary for the feed mechanism on the machine using the stock to hasrlimited the sizevof coil that. might be used.
tI-t is among the objects of the-present invention to provide a stock reel support and a feed ing mechanism for the coiled stock support on the reel so that the coiled stock is unwound and fedto the machine using the same at a rate determined by the machine requirements.
It is a further object of'my invention to :pro- 3, yidea stockreel with a power unit anda variable speed control device between the power unit and the reel so constructed and arranged tha h ed o :uncoiline s a omat ca .variedin response tothe changesin the requiremachinefs operation.
2 ments of the machine using the stock so that a stock coil weighing several tons may be used and the machine operated continuously for several hours with a single supply of wire.
It is a further object of my invention to provide a stock reel and stock feeding mechanism wherein the stock coming oh the reel is guided through a pivoted arm so arranged with respect to the machine using the stock that the position of the arm is varied by variations in the demand for stock in the machine using the uncoiled stock and wherein the changes in the positon of the pivoted arm change the rotational speed of the stock reel. V i i It is a further object of my invention to provide a stock handling apparatus according to the preceding objects wherein the unwinding of the stock and feeding the same to a machine is carried out in a manner compensating for the differences in diameter between the outer convolution of the stock in a coil and the innermost convolution of said coil.
Further objects and advantages relating to economies in manufacture and efficiency in operation will appear from the following description and appended drawings wherein:
Fig. 1 is a plan view of a stock reel and feeding mechanism constructed according to my invention; and
Fig. '2 is an elevation with parts in section of the stock reel and stock feeding apparatus.
Referring to the drawings, a base I is provided with an upright pedestal 2 for rotatably supporting the vertical shaft 3 which carries in its upper end a stocl; reel support i having a lower flange 5 and an upright tubular section B. The
nected andused for several hours withoutinterrupting the operation of the machine.
Machine's employed for making the bolts,
rivets, nails and the like usually include a stock feed mechanism mounted on the bed frame and operated in timed relation to the header slide movements so as to advance the proper length of stockinto the machine for each cycle of the Such conventional. stock feeding mechanism is indicated at it and includes stock-feed rolls, as at llQwhich are interm tent r ta ed b th dr in me han s 12 sojas'toia'dvance'alength'of stock for each cycle of the operation of the machine. The stock being unwound and advanced by the feed mechanism is is indicated at 13 and such stock is guided as it is being unwound through the fork it carried by the pivoted arm 55 and, as will be understood as this description proceeds, the position of the arm i5 determines the rate at which the stock will be unwound from the stock reels 8 and 9.
A vertically-extending supporting plate i6 is secured on the base i beneath the reel support table t and at one side of the plate i6 is supported a motor ll and at the other side of the plate is supported a speed change mechanism indicated as at it. The rotation of the motor is transmitted by belt 9 to the input shaft 23 of the speed change mechanism. The output shaft 2! at the top of the speed change mechanism includes a pulley and drive through belt 22 to a driven pulley carried by the reel support The speed change device it includes an operating A pair of adjusting screws 26 and 2'? are arranged :1
adjacent the inner end of the pivoted arm it so as to limit the range of pivotal movement of the arm [5. The motion of the arm 15 is transmitted to the controlling arm 23 by an adjustable linl: 23 connected at one end to the arm i5 and at the other end to the arm 23.
It will be noted that the angle at which the stock being unwound from the reel is disposed with respect to the feed mechanism IE3 and the yoke is of the arm 15 is such that an increase in the tension of the unwound stock between the reel 8 and the feed mechanism tends to swing the arm 55 in a counterclockwise direction, whereas a decrease in the tension in this section of unwound stock permits the arm 15 to swing downwardly in a clockwise direction to a position as indicated in the dotted lines of Fig. 2. Thus, it will be understood that an increase in the speed of the feed mechanism 55, as would occur when the machine using the stock was being accelerated, will put an additional pull on the stock being unwound from the reel and thus swing the arm 55 in a counter-clockwise direction to increase the output speed and hence the speed of reel rotation. Conversely when the feed mechanism it is decelerated or brought to a stop, the arm iii will move in a clockwise direction and thus decrease and/or eventually stop the rotation of the output member 2!. Although the speed change mechanism !8 illustrated is of the self-contained hydraulic type, it will be understood that other types of speed change devices may be employed such as, for instance, variable pitch v pulley and belt arrangements. It will also be appreciated that the movement of the arm i5 may be utilized to operate an excitation controller for a variable speed electric motor.
Although I have shown and described one form of my invention in considerable detail, it will be appreciated that numerous changes can be made therein without departing from the scope of the invention as defined in the following claims.
What I claim is:
