It is also necessary upon admission of a strip of material'to the coiling mechanism to start-outward adjustment of the coil forming elements at the proper instant and to stop such elements upon full upward movement thereof to permit removal of the coiled strip.
The present invention has among its objects to provide an automatic controller for reels of the aforesaid character which will insure operation thereof in the manner above stated.
4n embodiment of the invention which will now i at ' Another object is to provide a controller of the aforesaid character including manual control means enabling the operator to stop automatic adjustment of the coil forming elements at any point and to then efiect inward or outward adjustment of said elements Various other objects andmdvanta'ges 'of the invention will hereinafter appear.
The accompanying drawings illustrate an be described, it being understood that .vari
-ous modifications may be made in the em bodiment illustrated without departing from the spirit andscope of the appended claims.
In the drawings, Fig.1 is a schematic view of a strip winding reel, the parts thereof being the positions they occupy to being a coiling operation.
g mechspring by a rotatable cam 22 which engages shown in Fig. 2 is a view similar to that shown in I Fig. 1 illustrating the osition of the parts of the reel upon .comp etion of the coiling operation.
Fig. 3 is a schematic view' of the ejector mechanism of the reel, and
Figs. 4 and 5 diagrammatically illustrate a controller for the reel shown in Figs. 1 and 2 windingreel including a coilin mechanism 1, a gate 2 operable to direct .t e strip ma-. terial into such mechanism or to cause the same to pass therebe 0nd, and an ejector 3.
for removing theco mechanism.
The gate 2 is arran T of the reel and when t ed material from such ed upon. the table e same is in the pois deflected downwardly into engagement with a pair of driven pinch rollers 4 and 5.
Referring to Fig. 1, the same shows a strip '1 'sition shown in Fig. 1 the strip oflmaterial In leaving the pinch rollers the strip of material is fed between a pair of guide members 6 and 7 into the coiling mechanism. which comprises a plurality'of guide rollers 8 to 13,. inclusive, each Of'WlliCh has a deflectormember 14 associated therewith. Each of the ide' rollers is provided with means (not s own) for driving the same at.
a speed corresponding to the speed at which the material is fed into the coiling mechanism. Rollers 8 and 13 are mounted in stationary bearings and .the deflector member 14 associated with roller 8 is provided with.
an arm 15 for swinging the same about the axis of said roller. Rollers 9, 10, 11 and 12 and, their associated deflector members 14' are carried by pivoted arms 16, 17, 18 and 19, re-
spectively, and the arms 15 to 19, inclusive are connected by e plurality of links 20. of said arms are biased to the positions shown in Fig. 1 by a tension spring 21 and the same are adapted to be moved to the positions shown in Fig. 2 against the action of said,
suitable change speed gearing (not shown in the drawings) is provided for varying the.
speed at which the cam is rota When the coiling mechanism is in the position shown in Fig. 1 the rollers 8 to 13, inclusive, and their associated deflector members 14 act on the forward end of the stri as the same leaves the guide members 6 and ,to form said strip into a circular loop as in Fig. 2 and the coiLof material rests upon a stationary supporting member 24. The completed coil of material is removed from the coiling. mechanism by outward movement of the ejector member 3.' As shown in Fig. 3 said ejector member is mounted upon a sli'dable shaft. 25 which is adapted to be driven in opposite directions by a motor M through a suitabledrivin mechanism which is schematically illustrated at 26. Motor M is provided with suitable control means which is not shown in the drawing for effecting reverse movements of the e'ector member 3.
Re erring now to Fig. 4, the same illustrates a controller for motor M. Motor M is of a direct current type, the same being pro- 3 vided with an armature A and a shunt field Winding F and the supply circuit therefor is indicated by lines LL The armature circuit of said motor is controlled by an electroresponsive main switch 30, a pair of electroresponsive reversing switches 31 and 32 and an electroresponsive accelerating switch 33 while the field circuit of said motor is controlled by an electroresponsive relay 34 and an electroresponsive field switch 35. Each of the reversing switches is provided with normally'open up contacts and normally closed down contacts, and as is apparent from the drawing selective energization of said reversing switches provide for establishment of reverse power connections for the, motor armature. It is assumed, as hereinafter set forth, that reversing switch 31 provides for operation of the motor M in a direction to effect outward movement of the arms 15 to 19, inclusive, while reversing switch 32 establishes connections for operation of said motor in a reverse direction. Upon response of either of the reversing switches a resistance R is included in the armature circuit of the motor which is adaptswitch 30 and each of the reversing switches 31 and 32 and also by a series relay 36. The series relay 36 responds immediately upon establishment of power connections for the motor and drops out when the current in the armature circuit is reduced to complete the energizing circuit for accelerating switch 33 which then responds to shunt the resistance R Relay 34 is provided with a pair of windings 34 and 34 which are connected in series with the armature of the motor and immediately upon establishment of power connections for the motor armature said windings act cumulatively to efi'ect closure of their associated relay. Relay 34 in closing connects field F of the motor directly across lines L L for full excitation thereof. Accelerating switch 33 in closing shunts the winding 34 of relay 34- and under given current conditions in the armature circuit of the motor said relay drops out to open a shunt circuit around resistances R and R which are ermanently connected in series with the eld winding F of the motor. controls the resistances R and R to selectively exclude the same from the field circuit of the motor; As hereinafter set forth resistance R provides for slow speed operation of the motor while resistance B provides for high speed operation thereof and the switch 35 isprovid'ed with normalliy closed down contacts for normally exclu g the latter resistance. Switch 35 in responding includes the high speed resistance R in the field circuit of the motor and excludes the slow-speed resistance R.
Referring now to Fig. 5, the same illustrates control means for the main switch 30, reversing switches 31 and 32 and the field switch 35 of the above described controller, and also means for effecting operation of the gate 2. Such means includes a drum controller D, relays 40 to 44, inclusive, limit switches LS to L8", inclusive, a master switch and an operating solenoid 46 associated with gate 2.
Drumcontroller D is provided with stationary contacts 48 to 53, inclusive, and a movable contact drum having an intermediate ofi position, extreme forward and return positi 11s and two ofi positions which are lo 'cated intermediate said extreme positions and said neutral position. The contact drum is provided with a continuous contact ring 48 which engages contact 48, and in the neutral position of said drum contacts 49, and 51 engage movable contact 49, 50 and 51, respectively. Upon movement of the drum out of neutral position contacts 50 and 51 disengage their associated stationary contacts while contact 49 remains in engagement with contact 49. Upon movement of the drum'into either of its extreme positions contact 49 moves out of engagement with contact 49 and Field switch 35 when the drum is in its forward extreme position contacts 51 and 53 are engagedby-movable contacts 51' and 53, respectively. When the drum is moved into its other extreme posi- As hereinafter set forth relay 1S adapt I ed to be supplied with current from a low voltage generator G through the medium of an insulated roller 56 which is mounted on table T of the coiling mechanism in advance of the gate 2, while t e-relays 41 to 44, inclu- ,sive, and also the operating solenoid 46' associated with gate 2 are adapted to be supplied with current from lines L The limit switches LS to LS, inclusive are associated with the operating cam 22 of the coiling mechanism, while the limit switch LS is associated with the ejector '3. As
shown in Fig. 1, when the parts of the coiling mechanism are'positioned to begin a coiling operation limit switch LS is open while limit switches LS LS and LS are in closed position. Limit switch LS is normally open while limit switch LS is normally closed and upon initial movement of the cam 22 out of the positions shown in Figs. 1- and 2 the former limit switch closes while the latter opens. Limit switch LS is normally closed and opens immediately upon initial outward movement of the parts of the coiling mechanism and returns to closed position only upon restoration of the parts of the coiling mechanism to the position shown in Fig. 1.
l As before stated limit switch LS opens im- Limit switch LS is normally closed and opens only upon full outward movement of the parts of the coiling mechanism to the po-. sition shownin Fig. 2. The limit switch LS is associated with the ejector mechanism and is closed only when the ejector 3 is in its retracted position. I
The operation and circuit. connections of the control system will now be more fully described.
With the coiling inechanism in the ,position shown in Fig. 1 opening of gate 2 is efiected by de ressing push button 45. Depression of push utton establishes a circuit from line L through limit switch LS through push button 45 through the operating winding of relay 44 and thence through. the limit switch LS to line L Relay 44 thus responds and the ontacts 44" thereof shunt the limit switch LS while the contacts 44" thereof establish an energizing circuit for the gate operating solenoid 46 extending from line L through the solenoid 46 through the contacts 44 of relay 44 and the limit switch LS to line L.
mediately upon outward movement of the parts of the coiling mechanism but since the contacts 44 shunt the same as above described relay 44 is maintained energized to maintain the gate 2 in open position as long as push button 45 is held in closed position.
' to line L.
' Assumenow that the forward end of the strip of material approaches the gate 2. When said strip of material makes contact with roller 56 circuit is established from a ground connection Gr to the table T of the coiling mechanism, through the strip of ms?- terial to roller 56, through contacts 2 associated with gate 2, through the operating winding of relay 40, through the limit switch LS andthence through the generator-G to a ground-connection G Relay 40 thus responds and connects the operating winding of relay 41 across lines L 2 through the medium of its contacts 40. Relay 41 responds after a given interval determined by setting of its dash pot, and in closing connects the-operating winding of relay 42 across lines L L- Upon closure of relay 42 relay 40 is maintained energized by a circuit extending from ground connection G? through contacts .42 through contacts 40 associated with relay 40 through the limit switch LS and through the generator G to the ground connection G With drum controller D in its neutral p0,- sition and the coiling mechanism in the position shown in Fig. 1 relay 43 is energized'by a circuit extending from line L to contact 48 thrbugh contacts 48 and 49 to contact 49 and thence through limit switch LS and .the
operating winding ofsaid relay to line L.
should be noted that the field switcha35 is deenergized and thus resistance, R is included in the field circuit to provide for slow speed operation of the motor.
be noted that the relay 41 is energized immediately following engagement of the strip of material with roller 56 and after apredetermined interval relay 41 closes to eifect start- In connection with the'foregoing it should i ing of motor M for outward movement-of the shown in Fig. 1 limit switch LS closes to shunt the contacts 43 of relay 43 and in the meantime limit switch LS opens to interrupt the energizin The reversing switc 31 and main switch 30 are thus maintained energized through limit switch LS but-upon full outward movement of the parts of the coiling mechanism to the position shown in Fig. 2 said limit switch opens to deenergize said switches for automatic stopping of motor M. Also at this time limit switch LS opens to interrupt the afore-described energizing circuit for relay 40. Relay 40 in dropping 'out deenergizes relay 41 and relay 41 in dropping out deenergizes' relay 42. Also at this time the limit switch LS recloses whereby relay 43 is again energized as hereinbefore described.
Upon completion of the coilingoperation V the erator releases push button 45 to deenergize relay 44 and said relay in dropping out deenergizes solenoid 46 to permit closure of gate 2. The operator then ejects the roll of material from the coilingimechanism by efiecting operation of motor 1 so as to cause outward movement of the ejector 3. Limit switch LS opens immediately upon move.- ment of the ejector 3 out of its retracted position and it is thus apparent that the same insures opening of relay .44 to prevent opening of the gate 2 until ejector. 3 is returned to its retracted position. Also it should be noted that when the coiling mechanism is in the position shown in Fi 2 limit switch LS is open whereby push ut- 1 ton 45 is rendered inefiective to operate relay 44, which. operation as hereinbefore stated is necessary to efl'ect opening of gate 2. With gate 2 in closed position the strip material passes over said gate and cannot effect the aforedescribed automatic operation ofthe controller since the roller 56 is disconnected from the generator G by contacts 2".
After-ejection of the coil of material from the coiling mechanism such mechanism is re turned from the position shown in Fig. 2 to the position showriin Fig. 1 by movin the drum controller D to its extreme forwar position. In this position drum D establish'es an energizing circuit for the forward reversing switch 31 and main switch extending from line L to contact 48 through contacts 48 and 51" to contact'50 through the operating windings of reversing switch 31'and main switch 30 and through the contacts 43 of relay 43 to line L. Also with the drum in this position field switch 35 is energized by a circuit extending from line L? to contact 48 through contacts 48 and 53 to contact 53 and thence through the operating winding of said field switch to line circuit of said relay.
M is operated at a'relatively high speed to return the coiling mechanism from the position shown in Fig. 2 to the position shown in Fig. 1. Immediately upon movement of the coiling mechanism out of the position shown in Fig. 2 limit switch LS opens to interrupt the energizing circuit for relay 43 but in the meantime limit switch LS closes to maintain main switch 30 and reversing switch 31 energized. Upon full return movement of the coiling mechanism to the position shown in Fig. 1 limit switch LS opens to deenergize main switch 30 and reversing switch 31 for stopping of the motor.
During the aforedescribed automatic operation of the coiling mechanism from the position shown in Fig. 1 to the position shown in Fig. 2 the motor can be stopped at any t me by moving the drum controller D into either of its oil' positions. When drum D is moved to either of its oil positions contacts and 51-disengage their cooperating stationary contacts to thereby deenergize the main switch 30 and reversing switch 31 for interruption of the-motor circuit.
Drum controller D also provides for operation of motor M in a reverse direction. Upon movement of the drum D into its extreme reverse position reversing switch 32 and main switch 30 are energized by a circuit extending from line L to contact 48 through contacts 48 and 52 to contact 52 through the operating windings of said main switch and reversing switch and either through v contacts 43 of relay 43 or the limit switch LS to line L Also during reverse operation of the motor, field switch 35 is energized by a circuit extending from line L to contact 48 through contacts 48 and 53 to contact 53 and through the operating winding of said field switch to line L. As hereinbefore set forth energization of the field switch 35 provides for high speed operation of the motor.
