DEVICE FOR AUTOMATICALLY REELING STRIPS F STAMPINGS Andrew Raiche, Quincy, Mass., assignor to The National Marking Machine Company, Cincinnati, Ohio, a corporation of Ohio Application November 9, 1931, Serial No. 573,910

12 Claims.

This invention relates to the forming of identification tabs formed of comparatively thin sheet metal and adapted to be placed on laundry articles by mechanism similar to that described in the application of John Griesinger, filed June 8, 1931, Serial Number 542,885. The above mentioned mechanism is adapted to support tabs from a continuous strip of sheet metal, the individual tabs being connected together and severed by the tab ahixing machine at the time the tab is applied.

These tabs, which will hereinafter be referred to as stampings, are formed of a strip of thin sheetsmetal by means of an ordinary punch press and die. The stock is fed to the press by automatically controlled means, such as described in my co-pending application for patent on Stock feeder for punch presses, led November 9, 1931, Serial Number 573,909. It is desirable to wind 20 the stainpings thus formed in coils and market them in this form for use on the tab afxing machine.

The object of this invention is to provide a mechanism for reeling the strip of stampings as it is delivered from the punch, and for severing the stampings from the main strip when a predetermined number has been Wound in a coil, the counting, severing and reeling mechanism being automatically operated and controlled by the punch press reeled at the same speed at which it is fed through the press.

. A further object is to provide an automatically operated reeling device for winding strips of stampings in coils as the stampings are fed from a punch press, and to provide in connection therewith means for automatically severing the reeled portion of the strip from the main strip when a predetermined number of stampings has been wound on said reel, and means in connection therewith whereby the coil may be easily bound before being removed from the reel. f

A further object is to provide in an automatic device for reeling strips of stampings means for supporting a series of spools whereby each spool may be progressively advanced to operative position for receiving stock in such a manner that time is provided for the removal of the stock from some of the spools while one of the spools is being wound, and in connection therewith means for automatically operating the spool being wound and for automatically advancing the spool supporting means when said spool has been filled.

' A further object is to provide in an automatic device for reeling stampings' an improved spool so in such a manner that the stock is` constructed that the strip of stampings wound thereon may be easily bound Vand easily and quickly removed from the spool.

A further object is to provide in an automatic device for Winding strips of stampings into coils improved means for severing the wound coil from the main strip when a predetermined number of stampings has been wound thereon.

A further object is to provide in an automatic device for reeling strips of stampings automatically operated means for operating and controlling said reeling mechanism, and in connection therewith electrically operated means controlled by the counter for severing the coil of stampings from the main strip when a predetermined number of stampings has been wound on said. coil, and for automatically moving a second reeling mechanism into operative position as a reel is removed, and in connection therewith means for automatically feeding the stock to the second reeling mechanism.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 12 is a diagrammatical View of the counter showing the manner in which itis applied to the strip of stampings.

Figure 13 is a side elevation or" the shear for severing the strip of material, as detached from its operating mechanism.

My improved device comprises a base 10 having a top portion 11 terminating in an elevated portion 12. Supported on the portion 1l is a pair o1' upright standards 13 designed to support a horizontally arranged shaft 14 adapted to carry a reel 15, which will hereinafter be more fully described.

The portion 12 is provided with upright standards 16 supporting a cam shaft 17 designed to carry cams for controlling the reel 15 and the spool mechanism carried thereby.

The reel 15 is provided with a series of spools 18 for winding strips of stampings from a stock strip 19. Said strip 19 is carried by a suitable guide 20. A shear 21 is provided for severing the coil of stock 22 from the strip 19 when a sumcient amount of stock has been reeled on the spool. Each of the spools 18 is mounted on a shaft 23 rotatively mounted in the rim of the reel 15. The opposite end or each of the shafts 23 is provided with a friction wheel 24 (see Figures 5 and 6) so arranged that rotation of the friction wheel 24 will cause the spool 18 to be rotated in'an anti-clockwise direction, as illustrated in Figure 1.

Each of the spools 18 comprises a flange portion 25 and a cylindrical portion 26, which provides means for supporting the coil of stock. Each of the portions 26 is provided with a groove 27 (see Fig. 4) so arranged that a tongue 28 is formed in the member 26, which has a shoulder 29 against which one end of the stock is clamped by means of a pivoted dog 30, which is also mounted in the groove 27, said dog being moved to its closed position by means or a spring 31 threaded on a guide rod 32, one end of which is pivoted to said dog.

The dog 30 has a jaw 33 for clamping the stock adjacent to the shoulder 29. The jaw 33 is provided with a plate 34, one end of which projects through the groove 27 beyond the periphery of the member26 when the jaw 33 is in its closed position, in such a manner that when stock is reeled on the member 26 by rotating said member, the inner coil of the stock will be supported a slight distance from said periphery to increase its diameter, whereby when the jaw 33 is moved to its open position, the plate 34 will be moved inward- Vly to position within the groove 27, so that the coil of stock may be easily removed from the spool.

The member 30 is mounted on a shaft 35 which projects inwardly from the inner surface of the flange 25 and terminates in a head 36 supported adjacent to one side of the rim of the reel 15, in the manner clearly illustrated in Figure 6. It will readilyk be seen that rotation of the shaft 35 .will move the jaw 33 to an open position against the action of the spring 31.

The operation of the member 36 is accomplished by providing on the periphery of the reel l5 a block 37 in which is slidably mounted a trip bar 38 and a locking bar 39. One end of the bar 38 is designed to be moved outwardly in such a manner as to be engaged by the member 36 when the spool 18 is rotated relative to the reel 15, and to cause the jaw member 33 to be moved to its open position. At the same time the bar 39 is moved in the opposite direction by means of an actuating bar 40 pivoted to the block by a bolt 41 and designed to receive a pin 42 projectingv outwardly from the bar 39 through a suitable slot 43.

The bar 40 is connected with the trip bar 38 by a pin 44 operating in a slot 45. The outwardly projecting end of the bar 39 supports a spring actuated pin 46 designed to engage the inner face of the wheel 24 as the bar 40 is rocked in a clockwise direction, as illustrated -in Figure 6.

Assuming that the coil 22 has been completely formed and severed from the main strip, and it is desired to remove the coil from the spool, then the operator grasps the friction wheel 24 in one hand and the actuating bar 40 in the other hand, the actuating bar being moved to the position shown in Figure 6, after which the friction wheel 24 is rotated until the head 36 engages the pin Further rotation of the wheel 24 will cause the jaw 33 to be released and the plate 34 moved inwardly, and at the same time the pin 45 will enter a depression 47 in the face of the wheel 24, locking the jaw 33 in its open position against the action of the spring 31, after which the coil 22 may be removed. The inward movement of the plate 34 permits the coil to loosen on the member 26.

The jaw member 33 is thus locked in its open position until the spool is moved to operative position in front of the feeder, wherein the bar 40 is actuated automatically by means hereinafter described to unlateh the pin 46 and to permit the jaw member 33 to move to its closed position.

For retaining the strip of stampings on the member 26 as the spool is rotated for winding, I have provided an arm 48 having one end pivotally connected to the adjacent spoke of the reel 15 by means of a pivot member 49. A spring 5o is provided for normally moving the free end of the arm 48 inwardly toward the spool. The free end of the arm 48 is provided with a flanged pulley 51, the strip of material being fed between the pulley and the member 26.

The pulley 5l provides means for retaining the free end of the strip of stampings after the coil has been severed from the main strip until the operator has had time to tie the loops of the coil. Radial notches 52 are provided in the flange 25 through which wires may be fed through suitable slots 53 in the periphery of the member 26 so that the wires may be tied around the coil ofstampings before the coil is removed from the spool. Y

On the reel 15 I have provided eight spools so the operator may have suflicient time to tie the coils before removing them from the spools, while other spools are being wound, and so that the windinfY operation need not be discontinued only during the time the reel is being rotated to replace a wound spool with an empty spool. V

For rotating the reel 15 I have provided on the inner end of the hub of said reel a disk 54 having eight notches 55. A pawl 56 is provided having one end designed to engage one of the notches 55 and to lock the reel against rotation with one of the spools 18 in proper' feeding position.

The pawl 56 is retained in a locking position by means of a spring 57 and released by means of a link 58. Said link 58 has one end connected to the lower end'of an arm 59 secured to the outer end of a shaft 60 on which the pawl 56 is mounted. The other end of the link 58 is pivotally connected to the upper end of an arm 61 having its lower end pivoted to a bracket 62 carried by the base l2 (see Figs. 10 and 11).

The arm 61 has a roller 63 designed to engage the periphery or" a clutch drum 64 carried by one end of the cam shaft 17. The peripheryoi lil@ lli)

pivoted to the side of the casing 87.

the drum 64 has a cam portion 65 for actuating the lever 61 as the clutch member 64 is rotated.

As the pawl 56 is moved to a released position, the reel is rotated by means of a pawl 66 carried by a rock arm 67, the lower end of which is connected to a link 68 having its forward end pivotally connected to a lever 69, the lower end of which is pivotally connected to a bracket 70 carried by the member 12 (see Fig. 4.)

The lever 69 is provided with a roller 71 designed to operatagi the cam groove in the face of the cam 72, said cam also being secured to the shaft 17.

Thus means is provided for rotating the reel 15 an eighth of a revolution to move a filled spool out of operative position and to place an empty spool therein. 1n this connection it should be understood that all of the cams mounted on the shaft 17 and the clutch member 64 make one complete revolution and then come to rest.

The clutch 64 is fixed to the shaft 17 and driven by a gear 73 loosely mounted on the said shaft 17. Said gear 73 is rotated by a pinion 74 operated by a sprocket 75, said sprocket and pinion being mounted on a counter shaft 76. 'Thus means is provided whereby the gear 73 will be continuously rotated in one direction.

The inner face of the gear 78 is provided with a series of lugs 77 designed to be engaged by a slide bar 78 carried by the clutch member 64. A spring 79 is provided for forcing the inner end of the bar 78 outwardly to engagement with the lugs 77. The inner end of the bar 78 is provided with a laterally extending portion 80 adapted to l receive the upper end of a lever 81 between the outer face of the member 64 and the 'inner face of the portion 80. The upper end of the lever 81 normally retains the latch 78 at its inner limit of movement. The latch bar 78 is released by moving the lower end of the lever 81 in a counter-clockwise direction as illustrated in Figure 10, causing the upper end of the bar 81 to disengage the ange 86, thereby locking the member 64 to the gear 73, and permitting said clutch member to rotate one revolution at which time the lower edge of the flange 89 will engage the upper end of the bar 81. Said upper end has a beveled portion 82, causing the latch 78 to be wedged inwardly and the clutch member 64 stopped.

For actuating the lower end of the bar 80, which pivoted to the bracket 62 at the point 83, I have provided a slide bar 84 pivotally connected to said lever. The inner end of the slide bar 84 is connected to a slide rod 85 lby means of a bolt 86. Said rod 85 extends through a casing 87 in which is mounted an electric solenoid 88 having a movable core 89, the lower end of which is pivotally connected to a bell crank lever 90 The lower end of the lever 98 is designed to engage the free end of a pivoted bar 91, one end of said bar being pivoted to one end of a link 92, the opposite end cf said link being mounted to the side of the casing 87 by a pivot 98.

The opposite end of the bar 91 is pivotally connected to an arm 94 ixed to the slide bar 85. A spring 95 is mounted on the rod 85 in such manner as to tend to move the rod 85 to the right, as viewed in Figure l0, which in turn will tend to throw the left hand end of the bar 91 upwardly, said bar being held downwardly by the bell crank 9G. 1f the solenoid 88 is energized, then the core 89 will be lifted, causing the lower end of the member 90 to be moved outwardly from the link 91, permitting the free end of said bar 91 to be elevated and allowing the member 94 to move to the right, which in turn will move the lower end of the lever 81 to the right, causing the upper end of said lever to disengage the latch bar 78 and permitting the clutch member to rotate.

After the said clutch member has started to rotate, a roller 96, carried by the clutch memu ber, engages the horizontal portion of the bell crank lever 97 pivcted to the bracket 62 at the point 98. The lower end of the bell crank 97 is designed to engage a pin 99 carried by the bar 84 and to move the said bar 84 to the left against the tension of the spring 95, and to cause the parts 98 and 91 to be returned to their normal latching position.

For energizing the solenoid, 88 have provided an electric circuit including conductors 160 and 101, the conductor 101 having a spring contact member 162 designed to engage a contact member 103 carried by one of the roller carrying wheels of the counter 164. The units wheel of said counter has a series of pins 195 designed to engage the shoulders 106 of the strip of stock 19.

Thus means is provided whereby when the counter has rotated a predetermined number of revolutions, the contact member 163 will engage the contact member 102, closing the electric circuit in which is included a battery 107 causing the solenoid 88 to be energized, and causing the shaft 17 to rotate through one cornplete revolution at which time the shear and the mechanism for operating the spool and reels are operated.

For rotating the spools 18 nave provided a suitable bracket 168 (see Figs. 1 and 4). Carried by the bracket 108 is a shaft 199, one end of which is provided with an arm lll) designed to support a shaft 111. One end of the shaft 111 is provided with a friction wheel 112 designed to engage one of the friction wheels 24 before described.

A ratchet 113 is secured to the wheel 112 and is operated by a pawl 114 carried by a rock arm 115. Said rock arm 115 is connected to a link 116, which in turn is connected to the punch press in such a manner that each time the punch press is operated, the link 116 is reciprocated, causing the friction wheel 112 to be rotated through a partial revolution and in turn the friction wheel 24. The opposite end of the shaft 111 Ais provided with a roller 117 designed to engage the upper surface of the strip 19 as it is fed to the spool 18.

The arm 110 is provided with a downwardly extending portion 119, to which a spring 120 is attached for yieldably retaining the friction wheel 112 in contact with the friction wheel 24. The shaft 169 is provided with a downwardly extending arm 121 having a roller 122 on its lower end designed to engage the periphery of the cam 72. Said roller 122 is designed to coact with a flange 123 carried by said cam, whereby the friction wheel 112 may be lifted out of engagement with the friction wheel 24 at the time the filled spool is rotated out of operative position.

For advancing the stock after an empty spool has been moved to operative position and after the completed coil has been severed from the main strip of stock, I have provided a supporting bracket 124 carried by the member 12, the upper end of which is provided with guides 125 (see Figs. 1 and 2).

Slidably mounted in the guides is a block 126 having upwardly extending lugs 127 to which a lever 128 is pivotally connected. The rear end of the lever 128 is provided with a clamp member 129 for clamping the stock 18 to the upper surface of the rear end oi the block 126, and provide: means whereby when the block 126 is moved rearwardly, the free end or" the stock will be moved rearwardly and to position between the jaw member 33 and the shoulder 29 before described.

For operating the slide block 126 I have provided a pivoted lever 136 connected at its upper end with said block by a link 131. A roller 132 is mounted on the lever for operating in the groove 133 in the face of the cam 134.

The block 126 is provided with a laterally extending portion 135 (see Fig. 7), in which is slidably mounted a block 136 designed to move vertically. The upper end of the block 136 makes connection with the forward end of the arm 128 by means of a set screw 137, so that upward movement of the block 136 will cause the rear end of the arm 128 to be lowered.

For applying upward pressure to the block 136 as the block 126 is moved rearwardly, I have provided brackets 138 and 139 secured to the inner face of the member 124i. IThe bracket 138 supports a rock shaft 146, one end of which is provided with an upwardly extending link por tion 141. rThe bracket 139 is also provided with a similar shaft having an upwardly extending link 142.

The free ends of the links 141 and 142 are provided with a track member 148 (see Fig. 4) designed to a roller 144 in tie lower end oi the block 136. The shaft is provided with a rock arm 145, the free end of which is connected to the upper end or. a link 146, the lower end of said link being connected to the pivoted lever 147, tne free end or" which is provided with a roller 148 designed to travel in a groove 149 in a cam 15o carried by the shaft 17.

ilhus means is provided when said caro is rotated, the track member 143 will he elevated, causing the block 136 to he elevated and in turn the arm 128 operated to clamp the stock to said block, after which said block is moved rearwardly in the manner before described. The bar 146 is then loweredbefore the block 126 is returned to permit the jaw 129 to release the stock. The free end or" the stock is held by the jaw member 33.

To prevent movement of the stock 19 after theI contacts 102 are closed and before the clamp 129 is moved to closed positionl have provided the following mechanism:

Secured to the iront end of the member 78 I have provided a bracket 151 having an upwardly extending portion 152. The upper end of said portion pivotally supports a bell crank lever 153, the lower end of which is connected to a link 154 carrying a shoe 155 slidably mounted in a guide 156 (see Fig. 2). The forwardly extending por-y tion of the bell crank lever 153 is connected to the upper end of a 157 having its lower end connected to an arm 158 carried by a shaft 159.

The link 157 includes a spring 160 to impart yieldable pressure to said link. The inner end of the shaft 159 is provided with a downwardly extending arm 161 which operatively connected to the outwardly extending end of the rod 85 in such a manner that as the rod 85 is moved to release the member 91, the arm 158 will be rocked, causing the arm 153 to be rocked by the link 157,

which in turn will force the shoe 155 downwardly into engagement with the stock 19. Said stock is firmly held until after the clamp 129 engages it.

l will now describe the mechanism for severine; the completed coil from the strip 19. Secured to the inner edge oi the frame member 125 l have provided a bracket 162 to which a lever 163 is pivotally connected by means oi a shaft 164. One end of the lever 163 `provided with an upwardly extending portion 165. The upper end of the portion 155 is provided with a h d portion 168 terminating in a jaw member 16761 the shear.

Pivoted to the head 165 is a second jaw member 168 having an outwardly extending portion 168 Ehating in an upwardly extending portion 170. @ne end of a spring 171 is connected to the member 178 by a pin 172. lower end oi' spring 171 is connected to a lug 173 ycarried the by the outer end of the lever 153.

Pivotally connected to the portion 165 is a pawl 174, the upper end of which is designed to engage a lug 175 carlied by the member 169 and designed to normally support the jaw members 167 and 168, in an open position, as illustrated in Figure 8, with the spring 171 under tension. The lower end of the pawl 174 is provided with a set screw 176 designed to engage one edge oi member 177 as the shear is moved to its dotted line position, as illustrated in Figvre 8, and to cause the pawl to release the lug 175 and to permit the spring 171 to close the jaw members and sever he strip 19.

It will clearly be seen that if the free end of the lever 168 is elevated, then the jaw members 167 and 168 will more to position to straddle the strip 19. s the free end ci the lever 163 is moved downwardly, tle outer end of the member 169 engages a 178 carried by a bracket 179, causing tension 'tc be applied to the spring 171 and the jaw opened, permitting the pawl 174 to 1 engage the lug 175.

For operating the lever 168 l. have provided a cam 180 having a groove 181 for receiving a roller 182 carried by a lever 183, the of said lever making operative connection with the free end of the lever 163 by the link 184. Thus means is provided whereby the stock 19 may be severed when a coil has been completed. The cam 180 is operated by the shaft 17.

For operating the actuating bar 40 to release I.

the pins 38 and 39 when stock has been fed into the jaw 33, I have provided a rock arm 185 (see Figs. 4 and 5), having at its upper end a roller 186 designed to engage an outwardly extending pin 187 carried by the 40 in such manner that as the upper end of the arm 185 is moved toward the reel 15, the roller 185 will engage pin 187 and cause the bar 48 to be rocked in an anticlockwise direction withdrawing 'the pins 38 and 89 and releasing member 36.

The arm 185 is pivot-ally connected to a suitable bracket 188 and provided with a horizontally extending arm 189 and a roller 196 designed to operate on the periphery of the cam 150, and thus provide means for releasing' the stock clamp of j;

counter-clockwise direction by the f iction wheel 112, then it will be seen that as the spool 18 is rotated, the strip of material will be drawn through the guide 20 and beneath the roller 117, the speed ratio between the friction wheels 24 and 112 being such that the stock will be wound on the Vspool and moved at a speed slightly greater than the speed at which the stock is delivered by the press, so that the strip of stock as it is fed through the guide 29 is always maintained in a taut condition, slippage taking place between the wheels 112 and 24 to compensate for any variation in the speed ratio of the wheels due to dragging action of the strip as it is fed.

This also compensates for the variation in the diameter of the coil of stock as it is being wound. The pivot arm 48 and the roller 51 guide the stock on the spool as it is wound.

After a predetermined number of tabs have been wound on the spool, the contact members 102 and 103 are closed, causing the solenoid 88 to be energized and the slide bar 78 of the clutch mechanism moved to position to be engaged by one of the lugs 77 of the continuously moving gear wheel 73. At the same time the foot 155 is moved downwardly to clamp the stock against further movement.

As soon as the cam shaft 17 starts rotation, the jaw member 129 is moved downwardly on the stock through the action of the cam 150 and the lever and link mechanism above described. This provides means for holding the stock to permit the member 155 to be released at the time the roller 96 engages the member 97, and returns the member 91 to its normal position. The lever 163 of the shear is then actuated, causing the jaw members 167 and 168 to move to position relative to the stock and the coil to be severed from the strip 19`at a point between the clamp 129 and the spool 18. This operation takes place by the cam 180 and the link mechanism connecting the cam and said lever.

The lug 123 of the cam 72 then engages the roller 122 of the arm 121 causing the friction roller 112 to be elevated and to disengage the wheel 24, and at the same time moved out of the path of the wheel 24 as it is rotated about the center of the reel.

The cam 65 of the clutch 64 then engages the roller 63 and causes the pawl 56 to disengage the notch 55 ofthe wheel 54. The 'arm 67 is then rocked by the link 68, which in turn is actuated by the cam 72 and the arm 69, causing the reel 15 to be rotated in an anti-clockwise direction through an eighth revolution, and at the same time moving the lled spool upwardly and an empty spool into operative position.

In this connection it should be borne in mind that the jaw member 33 is locked in its open position as illustrated in the empty spool of Figure 4. The space between the jaw 33 and the shoulder 29 is in alinement with the severed end of the stock 19, The block 126 is then advanced toward the spool by means of the cam 134, causing the free end of the stock to be fed between the jaw member 33 and the shoulder 29. The lever 189 is then elevated by the periphery of the cam 159, causing the rolier 186 to engage the end of the pin 187 of the operating bar 49, said bar 40 being rocked to withdraw the bar 3S and 39, permitting the spool to rotate and releasing the tension of the spring 31, and permitting the jaw 33 to move to closed position. The clamp 129 is then returned to its normal position by movement of the block 126, at which time the cam shaft 17 will have made one complete revolution and the latch bar 78 withdrawn from engagement with the lug 77, the friction roller 112 having again engaged the friction wheel 24 of the second spool, after which the second spool is again rotated in an anti-clockwise direction and the winding operation continued.

Thus it will be seen that I have provided an improved device for automatically winding strips of stampings on suitable spools, in such manner that the coils formed thereon may be easily tied, and when sol tied may be easily and quickly removed from the spool. Y

It will further be seen that by mounting a series of spools on a single reel and operating the reel automatica-ily, a comparatively short length of time is necessary for transferring a new spool to operation position, so that the operation of the press does not need to be discontinued during the transferring of spools.

Furthermore, means is provided whereby sufficient time is given the operator for removing the spools while others are being wound.

It will further be seen that by providing means for automatically counting the number of tabs on each spool, and in connection therewith means for automatically controlling the operation of the various mechanisms for severing the stock and placing new spools in operative position, delays and inaccuracies are thereby eliminated.
