l2 Claims.
This. invention relates to hydraulic drives of the type employed to drive a winding roll upon which strip material is wound as fast as it is delivered thereto from another machine orfrom another part ofthe same machine of which the winding roll forms a part.
v A Winder drive must maintain tension upon the strip during the winding operation and the tension must be maintained within certain limits in order to produce a nished roll of strip material having the) proper density and to prevent the inner turns ,'oftliezstrip from moving axially during the winding of the outer turns.
The present invention has as an objectto provide a hydraulic drive which will wind strip material into large diameter rolls upon small diameter cores and maintain the tension upon the strip within the proper limits.
Other objects and advantages will appear from the following description of an embodiment of I the invention shown schematically in the accompanying drawing. l
The drive chosen for illustration is adapted to drive the winding shaft I of a machine which winds a sheet or strip 2 of material into a roll as it is delivered thereto by the delivery rolls 3- of the same or a different machine. Since the machine or machines form no part of the present invention, only the winding shaft and the de-l livery rolls thereof have been shown in the drawing.
As shown, 'winding shaft I is adapted to be driven by a hydraulic motor 4 throughl a suitable drive 5 and also by a second hydraulic motor 6 through a suitable drive 1 which should include an overrunning clutch 8. -JDrives 5 and 1 have tor E through an adjustable choke "I5 and an adjustable resistance valve I6 which are connected in series between channels II and I2. Chokes- I3' and I5 are preferably of the orifice type.
Operation 'I'he end of the strip extending through delivery roll 3 is fastened to a core on a shaft I with as little slack as possible. Delivery rolls 3- are then started and pump `9 will start to operate. 'I'he liquid delivered by pump 9 will flow through channel IU and cause motor d to rotate shaft I which will wind strip Zthereon.
Resistance valve Id will at rst prevent .de-v livery of liquid to motorv 6 so that all the liquid discharged by pump Q will flow to motor 4 until the slack is pulled .out of strip 2' and tension is exerted thereon. `The pull on strip 2 will cause pump pressure to rise high enough to open resistance valve Id which is adjusted to open at the pressure necessary to enable motor 4 to have just enough torque to exert the proper tension upon strip 2 when the roll of material upon shaft I is of minimum diameter.- Overrunning clutch 8 ypermits motor 4 to drive shaft I independently of motor 6.
As delivery rolls 3 accelerate to full speed, the speed and volumetric delivery of pump 9 will correspondingly increase and cause motor I to run been shown as being of the belt and pulley type solely for `the purpose of illustration as any suitable "type of drive will sumce. Drive l has been shown as having a greater ratio than drive 5v so pump 9 by a channel III and its outlet connected to a channel II through which liquid is returned f to pump l9. Motor i has its outlet connected to channel II and its inlet connected to channel III by a channell I2 and an adjustable choke I3 and 'an adjustable resistance valve I 4 which are conthat motor 8 will'run faster than motor 4 when fast enough to wind up strip 2 and to maintain tension thereon. The liquid discharged by pump 9 in excess of the liquid required to operate motor 4 ilows through choke I3, resistance valve Il and channel I 2 to motor and causes it to operate-but it will not run fast enough to assist in driving shaft I 'until the roll of material thereon reaches a predetermined diameter. For example, if the core on shaft I is three inches in diameter, the parts may be so proportioned that motor i is not effective until the roll of material on shaft I is about seven and one half inches in diameter;
As the roll of material upon shaft I gradually increases in diameter, more motor torque is required to rotate it and its rotary speed decreases relative to its peripheral speed and 'causes the increase. f
nected in series. Liquid is bypassed around mo- Continued rotation of shaft I causes the roll of material thereon to gradually increase in diameter so that the motor torque must gradually increase in order to maintain tension upon strip 2.' Since strip 2 is delivered to shaft I at a substantially uniform rate after the machine is I of liquid therethroughis small when the roll l of material on shaft I is of minimum diameter but, as the ow therethrough gradually increases due to the roll of material gradually increasing f in diameter, the resistance of choke I3 gradually increases and causes pump pressure to gradually increase and thereby gradually increase the torque ofV motor 4 so that tension is maintained upon strip 2.
All of the liquid bypassed through choke I3 f and resistance valve I4 enters motor 6 but the rate of flow is insufficient to cause motor 6 to 4operate fast enough to assist in driving shaft I until the roll of material reaches a predetermined diameter so that at this time the pressure in channel' I2 is just high enough to cause motor 6 to operate idly. v
When the roll of material on shaft Ireaches the predetermined diameter, the speed of motor 4 will have been decreased to such an extent `that the flow of liquidtlrroughr choke I3 and resistance valve I4 will have been increased sufyilciently to cause motor 6 to operate fast enough to pick up the load through overrunning clutch Il. Shaft I will then be driven by both motors.
Since the speed of motor 4 is gradually decreasing so that theow of liquid to motor 6 is graduallyincreasing, motor 6 will tend to accelerate but its speed will be limited by the speed of strip 2. 'I'he resistance offered by strip 2 to the operation of motor 6 causes the pressure in channel I2 to rise and open resistance valve I6 and then the liquid delivered to motor 6 in excess of its requirements ows 'through choke I5 and resistance valve I6 into return channell I. The resistance offered by choke I5 is negligible at first for the reason that the flow therethrough is very small at rst but the speeds of motors 4 and 6 will gradually decrease as the roll ofmaterial on shaft I gradually increases so that the ilow through choke i I5 gradually increases and thereby causes pump pressure to gradually increase and enable motors 4 arid 6 to maintain tension upon strip 2.
The tension' on strip 2 is thus-automatically it is delivered thereto, comprising a pump, .a first hydraulic motor connected to said pump, a rst drive connecting said motor to said shaft, a second hydraulic motor, a second drive connecting said second motor to said shaft andincluding an overrunning clutch, means for delivering liquid from said pump to said second motor including means to resist `the flow of liquid thereto, and resistance means for bypassing liquid around said second motor.
2. A transmission for driving a shaft upon which strip material is to be wound as fast as it is delivered thereto, comprising a pump, a :Iirst hydraulic motor connected to said pump, a rst drive connecting s'aid motor to said shaft, a second hydraulic motor, a second drive having a greater ratio than said first drive connecting said second motor to said shaft and including an overrunning clutch, means for delivering liquid from said pump to said second motor including means to resist the tlow of liquid thereto, and resistance means for bypassing liquid around said second motor.
3. A transmission for driving a shaft upon which strip material is to be wound as fast as it is delivered thereto, comprising a pump, a viirst hydraulic motor connected to said pump, a first drive connecting said motor to said shaft, a second hydraulic motor, a second drive connecting said second motorto said shaft and including an overrunning clutch, means connecting said second motor to said pump in parallel with said first motor and including a choke and a resistance valve connected in series between said second motor and said pump, ard resistance means for bypassing liquid around said secondmotor.
4. A transmission for driving a shaft upon which strip material is to be wound as fast as it is delivered thereto, comprising a pump, a first hydraulic motor connected to said pump, a first drive connecting said motor to said shaft, a second hydraulic motor, a second drive having a greater ratio than said .first drive connecting controlled by chokes I3 and I5 and resistance valves I4 and I6 which are preadjusted to provide a tension of the desired characteristics. If a strip is to be wound into a roll of large diameter upon a small diameter core, such as a roll ten times the diameter of the core, the chokes and resistance valves are preferably so adjusted that the tension upon the strip is maximum at the beginning of winding operation and automatically decreases .as the roll-increases in diameter so as to preventthe inner turns of the strip from moving axially during the winding of subfl sequent turns of the strip. n A
