Hi5 Attorney BOBBIN LUGGER The invention relates to a bobbin lugger of the type disclosed in the Black application Ser. No. 877,621 filed Nov. 18, 1969, for Bobbin Lugger and assigned to the assignee of the present application where each lead lug of a number of lug strips is inserted into a slot formed in the bobbin with the ends of the inserted lugs exposed. After insertion, the exposed ends may be bent through an angle to confine the lug to the bobbin and to provide a tie point.

The present bobbin lugger utilizes a pair of like lugging assemblies and a feed bar which is sandwiched between the assemblies. Each assembly includes means for feeding one or more lug strips along the joint between the assembly and the bar to the work position at one end of the bar. Each assembly also includes means for clamping a bobbin in the work position against the end of the bar so that the lead lug of each strip is seated in a slot in the bobbin. When the lug is seated the lead end of the lug is located outside of the bobbin clamp in each assembly. The bobbin clamp is then moved laterally away from the bobbin to engage the lug lead ends and bend them through an angle so that they extend away from the bobbin. At the same time the lead lugs are severed from the lug strip. Means are provided to eject the lugged bobbin from the apparatus.

One of the lugging assemblies is secured to a support and the other assembly is moveably mounted on the support. When in the lugging position the two assemblies are secured together with the feed bar sandwiched between them. Means are provided to secure the bar to one of the assemblies so that when the moveable assembly is moved away from the fixed assembly the joint between the bar and the other of the assemblies is opened to facilitate clearing of jams in the lug feed or re-threading ofa new lug strip.

Each of the lugging assemblies may be used with different feed bars to lug bobbins of different types. Thus, the bobbin lugger is readily altered for different types with the minimum of ex ense and downtime. Both of the lugging assemblies are mounted on a flat support so that the parts thereof are readily accessible for servicing and maintenance.

Other objects and features of the invention will become ap parent as the description proceeds, especially when taken in conjunction with the accompanying drawings illustrating the invention, of which there are five sheets.

FIGS. 4, and 6 are sectional views taken along lines 4-4, 5-5 and 66 respectively of FIG. 2;

FIGS. 7, 8, 9 and 10 are partially broken away top views of the end of the feed bar illustrating the operation of the bobbin lugger;

FIG. 11 is a schematic view illustrating the electrical circuitry of the bobbin lugger;

FIG. 12 is a schematic view illustrating the pneumatic circuitry of the bobbin lugger;

FIG. 13 illustrates a strip of terminals which are applied by the lugger to a bobbin; and

FIG. 14 illustrates a bobbin with lugs attached.

As illustrated in FIG. 1, bobbin lugger 10 includes a flat table or support 12 on the top of which are mounted a pair of

like lugger assemblies

14 and 16. Feed bar 18 is located between

assemblies

14 and 16. Assembly 16 is fixably mounted on table 12 in the position illustrated in FIG. 1. Assembly 14 is slideably mounted upon the table so that it may be moved toward and away from assembly 16 in the direction indicated by arrow 20. Piston rod 22 of air cylinder 24, mounted on table 12, is secured to assembly 14 so that when the air cylinder is retracted the assembly 14 is moved away from assembly 16, as illustrated in FIG. 1, and when air cylinder 24 is extended the assembly is moved toward assembly 16 as illustrated in FIG. 2, and feed bar 18 is sandwiched between the assemblies.

Assemblies

14 and 16 are symetrical in construction with respect to the feed bar 18. Both assemblies operate simultaneously and in the same sequence. For these reasons the opera tion of the bobbin lugger 10 will be described with primary emphasis upon assembly 14 with it being understood that assembly 16 is like assembly 14 and operates in the same manner and simultaneously with assembly 14.

The sides 19 of feed bar 18

face assemblies

14 and 16. Three terminal feed grooves 28 are formed on each side of bar 18 as illustrated in FIG. 6. These grooves extend on each side of the bar from end 26, past a back-up latch recess 30 and to a feed recess 32 formed in the bar sides 19 as shown in FIG. 1.

Three lug or terminal strips 34, of the type illustrated in FIG. 13, are fed along paths 28 on each side ofthe bar 18 so in a single cycle of operation of the lugger 10. six individual lugs or terminals 36 are secured to a bobbin mounted on end 38 of bar 18. The strips 34 are fed toward the bobbin in the direction of arrow 40. The lead lug of each strip 34 is fed to end 38 through a passage 39 illustrated in FIG. 7. During the operation of the lugger, lug connecting portions 42 are blanked from the strips in order to sever the lead lugs from the strips after they have been secured to a bobbin.

Assembly 14 comprises a rectangular frame 44 formed from two

side members

46 and 48 and

end members

50 and 52.

Members

46, 48, 50 and 52 rest on top of table 12. Piston rod 22 of air cylinder 24 is secured to end member 50 so that extension and retraction of the air cylinder moves the assembly toward and away from fixed assembly 16. A pair of plates 54 are mounted on the top and bottom of end member 52 and extend toward bar 18. Spring biased back-up latch 56 is mounted on a pin extending between plates 54 and is biased toward cover plate 58 on member 52, as illustrated in FIG. 2. The terminal strips 34 are positioned between the back-up latch 56 and the exposed surface of feed track cover plate 58. Thus, when the air cylinder 24 is extended and bar 18 is sandwiched between

assemblies

14 and 16, the terminal strips 34 are each confined in a feed path 28 formed at the joint between an

assembly

14, 16 and bar 18. The back-up latches are located in recess 30 and are spring biased against plate 58 so that they engage upwardly projecting tangs 60 on the strips to prevent upstream movement of the strips during operation ofthe lugger.

Feed slide 62 is moveably confined in recess 63 between bar 52 and plate 58. A pair of spaced feed finger brackets 64 are secured to the top and bottom surfaces of bar 18 and feed finger 66 is pivotally mounted on a pin extending between brackets 64 and is biased toward plate 58 by a spring 68. When the bobbin lugger is assembled as in FIG. 2, the feed finger 66 is positioned within feed bar recess 32 and biases the terminal strips 34 against plate 58. The lead end of the fixed finger engages tangs 60 to feed the terminal strips toward bar end 38.

An extension 70 on bar 62 projects from an opening in end member 52 toward member 50. Feed air cylinder 72 is pivotally mounted on the end of a bracket 74 projecting away from frame member 46. The cylinder extends into a recess 75 formed in member 46 and the piston rod 76 thereof is pivotally mounted to the feed slide projection 70. In the position illustrated in FIGS. 1 and 2, the feed air cylinder 72 is retracted and the feed finger 66 is located in the upstream position relative to the feed bar 18. Upon extension of the cylinder 72, the slide 62 is moved downstream relative to the bar 18 until extension 70 engages fixed stop 78. Downstream movement of the slide moves the feed fingers downstream a distance sufficient to seat the lead terminal of each terminal strip 34 in the bobbin held on bar end 38.

Each

lugger assembly

14 and 16 includes a bobbin clamp and lug bending and cutting sub-assembly 80. A slide block 82 is mounted on the front surface of side member 48 by a pair of guides 84 so that the slide is moveable toward and away from feed bar 18. Pivot link 86 is rotatably secured to fixed block 88 on the interior surface of bar 48. One end of the link extends through opening 90 in bar 48 and an opening 91 in block 82 and is secured to the block by means of pin 92. The other end of the link is secured to piston rod 94 of air cylinder 96. The air cylinder is mounted to end member 50 by pin 98. Air cylinder 96 is in the retracted position in FIG. 2 so that the slide 82 is located in the position adjacent the feed bar 18. Extension of cylinder 96 pivots link 86 to the position indicated by line 100 and moves block 82 away from the feed bar.

A pair of clamp bars 102 are also pivotally secured to block 82 by pin 92 and extend therefrom along the side member 48 toward the feed bar 18. When air cylinder 96 is retracted the bobbin clamping and lugging end 106 of head 104 located on the end of bars 102 is located immediately inside of the lug strips 34 confined in the feed grooves 28 on the left hand side of the feed bar, as illustrated in FIG. 2. The head 104 includes a clamp projection 107 which extends inwardly toward the end of the feed bar to clamp the bobbin 108 against the feed bar end 38.

Teeth 109 extend from head 104 toward clamp projection 107 to engage the side of the bobbin when it is mounted between the two slots 104 and the feed bar end 38 as illustrated in FIG. 7. The fingers 109 are spaced between the lug strip feed slots 28 in bar 18.

A clamp air cylinder 120 is pivotally mounted to the side member 46 at 122 The piston rod 124 of air cylinder 120 extends through an opening 126 in side member 48 and is connected to the clamp bar by pin 128. When the air cylinder is retracted the head 104 is moved toward the feed bar end 38 so that the bobbin 108 is clamped between the head and the bar.

FIG. 3 illustrates the front of the assembly 80. Cutter 130 is pivoted at 134 to a member 132 on support 48 immediately below the bar end 38 and includes a straight knife portion 136 which extends upwardly through a slot 138 in the feed bar 18 past the feed slots 39. The upper end of the cutter 130 is pivotally secured to slide block 82 by a link 140 so that when the slide 82 is moved away from the feed bar, the cutting edges of the knife 136 are swept past the feed slots 39 and the lead lugs are severed from the lug strips. See FIG. 4 and FIGS. 7 thru 9. When the slide 82 is moved to the position of FIG. 3 adjacent the feed bar, the cutter blade 36 is confined within the groove 138 and the lug strips may be fed to position the lead lugs thereon in the bobbin 108.

When the air cylinders 96 in each

assembly

14 and 16 are retracted and the air cylinders 120 in the assemblies are extended, the clamp heads 107 and fingers 109 are located sufficiently away from the end 38 of the feed bar 18 to permit bobbin 108 to be moved down a feed guide 142 to the work position on the end of the bar 18. A suitable stop is provided beneath the bar to hold the bobbin in the work position. FIG. 14 illustrates the side of the bobbin 108 which is held against the end of the feed bar. Feed bar vertical ridge 144 extends into a groove 146 into the end of the bobbin to assure that the bobbin is centered on bar 18. When in this position, the lug receiving slots 148 formed in the laterally extending bobbin flanges 150 are positioned in alignment with the lugs in bar 18. A pneumatically actuated ejector 152 is confined within ridge 144 and is moved outwardly of the ridge, as illustrated in FIG. 10, to eject the bobbin at the completion of the lugging operation. The ejector 152 is driven by an air cylinder 154 which is indicated schematically in the pneumatic circuit diagram of FIG. 12.

The

lugger assemblies

14 and 16 are secured together to sandwich the feed bar 18 therebetween by extending air cylinder 24 so that each of the assemblies abuts one side 19 of the feed bar. When in this position, as illustrated in FIGS. 2 and 6, tie bar 156 extends over the bar 18 and each of the plates 52 in

assemblies

14 and 16. The bar may be secured to feed bar and plates by

dowel pins

158, 160 and 162 which extend through the tie bar and into the respective members. When the dowel pins are inserted, as in FIG. 6, assembly l4,the feed bar 18 and assembly 16 are secured together in the operative position.

During operation of the lugger the lug strips 34 may jam in the grooves 28. Jamming requires that the lugger be shut down and that the jammed strip be removed and rethreaded through the carrier strip to eliminate the jam. In previous luggers the elimination ofjams was a difficult problem because the lugger had to be disassembled in order to attain access to the strip feed path. In the present lugger jams are easily removed by opening the space between the lugger assembly and the carrier strip where the jam has occured. Thus, if a jam occurcd between the feed bar 18 and lugger assembly 16, pin 158 would be removed and air cylinder 24 would be retracted to withdraw assembly 14 and and bar 18 secured thereto away from the fixed lugging assembly 16. The feed finger 66 and latch 56 hold the strips 34 adjacent the exposed plate 58 of assembly 16 and the feed paths 28 on the right hand side of the feed bar are then exposed. The jam may be readily cleared. When the jam is cleared air cylinder 24 is extended to move assembly 14 and bar 18 back to the position of FIG. 2. Pin 158 may then be re-inserted and the lugger may be reactivated.

In a similar manner jams occuring between the feed bar 18 and assembly 14 may be cleared by removing pin 162 and retracting air cylinder 24 so as to open the connection between the assembly 14 and the left hand side of bar 18. This condition is illustrated in FIG. 1. Opening of the lugger to either side of the bar 18 also permits ready inspection of the lug strips. When a strip is exhausted a new strip is loaded by feeding it along the feed path while the lugger is closed. By removing

pins

158 and 162 and retracting cylinder 24 the bar 18 may be removed from lugger 10.

The electrical and pneumatic circuits for lugging assembly 14 will now be described it being understood that similar electrical and pneumatic circuits are provided for assembly 16 so that both

assemblies

14 and 16 operate simultaneously. Thus, the description of the electrical and penumatic apparatus for assembly 14 and the operation thereof suffices to describe the operation of the entire apparatus 10.

FIG. 11 illustrates the electrical circuitry of the bobbin lugger. Leads and 172 are connected to an electrical power source. Lead 173 is connected to lead 170 through on/off switch 174. A number of pairs of normally open microswitches and

control solenoids

176, 178; 180,182; 184, 186; and 188, 190 are connected between

leads

172 and 173 so that closing of one of the

microswitches

176, 180, 184 and 186 energizes the

respective solenoid

178, 182, 186 or 190.

FIG. 12 illustrates the pneumatic circuitry for assembly 14. Pressure fluid source 192 is connected to

inlet ports

194 and 196 of solenoid control valves 198 and 200. The work ports of valve 198 are connected to air cylinder 96 so that when control solenoid 182 is energized, the air cylinder is extended. When solenoid 190 is energized, the cylinder is retracted.

The work ports of valve 200 are connected to air

cylinders

72 and 120 so that when solenoid 178 is energized, feed cylinder 72 is extended and clamp cylinder 120 is retracted. Because air cylinder 72 is larger in diameter than air cylinder 120 and has a longer work stroke, head 104 is brought against the bobbin 108 prior to completion of feeding of the lugs by air cylinder 72. Upon energization of solenoid 186, valve 200 is shifted and air cylinder 72 is retracted and air cylinder 120 is extended.

Pressure fluid source 192 is also connected to spring return valve 202 which is mounted on the edge of support 12 so that upon movement of the slide block 82 of assembly 16 away from the feed bar, the block engages the valve trigger and the valve 202 is shifted to extend air cylinder 154. When the lead block 82 is moved away from the valve spring 204 shifts the valve back to the normal position to retract air cylinder 154.

OPERATION OF THE BOBBIN LUGGER At the start of the cycle of operation of bobbin lugger 10, the feed bar 18 is sandwiched between the two

assemblies

14 and 16, air cylinder 120 is extended and

air cylinders

72 and 96 are retracted. Air cylinder 154 is retracted. Because the air cylinders 120 in each

assembly

14 and 16 are extended the respective clamp heads 104 are pivoted away from end 38 of feed bar 18 a slight distance sufficient to permit a bobbin 108 to fall down the feed to the position of FIG. 2 and 7 where ridge 144 is fitted in groove 146 and the bobbin lug receiving groove 148 are in alignment with the feed paths 28.

Following positioning of the bobbin on bar end 38, the operator momentarily closes microswitch 176 to energize solenoid 178 thereby shifting valve 200 to extend feed air cylinders 72 and retract clamp air cylinders 120 in assemblies both 14 and 16. The retraction of air cylinders 120 moves the clamp heads 104 against the bobbin 108 to clamp it securely against feed bar end 38 prior to feeding of the lead lugs past the cutters 130.

Following clamping of the bobbin, the extension of the feed air cylinder 72 moves the lead lugs 38 of each of the six lug strips 34 toward the bobbin and into recesses 148 so that the tie portions 204 thereof project outwardly of the bobbin recesses behind the clamp projections 107. The tangs 60 are seated in the recesses 148. This position is illustrated in FIG. 8.

Extension of the lug feed moves extension 70 to engage the trigger of normally open microswitch 180 so that at the end of the feed stroke the switch is closed to momentarily energize solenoid 182 and thereby shifting valve 198. Shifting of the valve extends air cylinders 96 in both

assemblies

14 and 16 to pivot links 86 and move blocks 82 away from bar 18 and slide the clamps 107 over the surface of the bobbin until they reach the position illustrated in FIG. 9. During movement of the clamp away from the feed bar cylinders 120 are biased toward a retracted position so that the clamps are held firmly against the bobbin. When the clamps are pulled past the bobbin they engage stops so that at no time are they moved closer to the side members 48 than illustrated in FIG. 9.

The movement of the clamps away from the bobbin while they are held in engagement with the bobbin brings the clamps against the lug tie ends 204 and bends the same outwardly of the bobbin through an angle of 90, as illustrated in FIG. 9. Bending of the lugs secures the lugs to the bobbin. Continued extension of the cylinders 96 moves the clamps past the lugs in the bobbin to the position of FIG. 10. The movement of the slide blocks 82 pivots cutters 130 so that knives 136 are moved past the lug strip feed paths 138 and cut away the connecting portions 42 between the lead lugs which are secured to the bobbin and the remainder of the lug strips. When the slide block 42 in assembly 16 has completed movement away from bar 18, it engages the trigger of valve 202 to shift the same and extend ejector air cylinder 154 thereby moving the ejector 152 so that the lugged bobbin is ejected from the apparatus. See FIG. 10.

When air cylinder 96 is fully extended, normally open microswitch 184 is closed to energize solenoid 186 and shift valve 200 so that clamp air cylinders 120 are extended and feed air cylinders 72 move the feed fingers 66 upstream so that they are located behind the tang 60 of the immediately upstream lugs of the strips 34. During retraction of the feed, back latches 56 prevent upstream movement of the strips.

Upon retraction of the feed, microswitch 188 is closed to energize solenoid 190 thereby shifting valve 198 and retracting air cylinder 96. When the air cylinder is fully retracted, the bobbin lugger is in the rest position with the bobbin clamps 106 positioned in front of feed bar end 38 to receive the next bobbin and cutter knives 136 positioned within recesses 38 to permit feeding of the lead terminal into the bobbin recesses 148. Spring 204 shifts valve 202 to retract cylinder 154 and move ejector 152 back into ridge 144. The operator may then position the next bobbin between the clamp and the feed bar and again close the switch 176 to reactuate the apparatus.

Apparatus is easily modified so that it may be used to attach lugs to different types of bobbins. The

basic lugging assemblies

14 and 16 may be used without modification. For a given bobbin an appropriate feed bar is provided having required feed paths therein for the bobbin. For instance, some bobbins may require two lugs on one side of the bobbin and three lugs on the other side. This is easily accommodated by forming a feed bar with paths at the right spacing. The bar end 32 is also formed to conform to the bobbin. Cutter grooves 138 are provided. If necessary, separate bobbin clamping and bending assemblies may be mounted on bars 102. The feed stroke is easily adjusted by means of stops. The stroke of cylinder 24 accommodates bars of different width.

By mounting assembly 14 so that it is readily moveable toward and away from assembly 16, it is an easy matter to modify the apparatus to lug different bobbins by installing an appropriate feed bar 18 between the assemblies. As mentioned previously, this feature also facilitates the clearing of jams which may occur in the lug strip feed paths.

While I have illustrated and described a preferred embodiment of my invention, it is understood that this is capable of modification, and I therefore do not wish to be limited to the precise details set forth, but desire to avail myself of such changes and alterations as fall within the purview of the following claims.
