The working of an invention form
Below, the 1st the form of implementation of the present invention being specialized with reference to Fig. 1 and Fig. 2 explanation.
As shown in Figure 1, main shaft 12 is supported on the bogie side frame 11 of loom rotationally.Fixedly mount passive belt wheel 15 in the end of main shaft 12.
Fixed installation driving pulley 18 on the output shaft 17 of loom CD-ROM drive motor M.On driving pulley 18 and passive belt wheel 15, take the V-type band 16 of circulation.Main shaft 12 obtains driving force by the driving force transmission mechanism that is made of driving pulley 18, V-type band 16 and passive belt wheel 15 from loom CD-ROM drive motor M.
The electromagnetic braking mechanism 13 of on loom CD-ROM drive motor M, packing into.As the electromagnetic braking mechanism 13 of the 1st arrestment mechanism, switch to on-position that loom CD-ROM drive motor M is braked and the braking disarm state of not braking.Electromagnetic braking mechanism 13 by the excitatory on-position that becomes, becomes the braking disarm state by demagnetization.
Assembling keeps frame 14 on bogie side frame 11, and is keeping that electromagnetic braking mechanism 19 is installed on the frame 14.As the electromagnetic braking mechanism 19 of the 2nd arrestment mechanism, switch to on-position of braking and the braking disarm state of not braking as the main shaft 12 of passive object.Electromagnetic braking mechanism 19 by the excitatory on-position that becomes, becomes the braking disarm state by demagnetization.Electromagnetic braking mechanism 19 only distolaterally brakes main shaft 12 at one of main shaft 12.
Electromagnetic braking mechanism 13,19 together is controlled the control of the C1 of mechanism with loom CD-ROM drive motor M.Controlling organization C1 makes loom CD-ROM drive motor M work according to the ON operation that moves starting switch 20.Along with the ON signal that the ON operation of operation shutdown switch 21 is exported, input controlling organization C1.Controlling organization C1 stops the work of loom CD-ROM drive motor M according to the input of the ON signal (weaving stop signal) that comes self-operating shutdown switch 21, and makes electromagnetic braking mechanism 13 excitatory.Again, controlling organization C1 cuts off the output that monitor etc. is weaved the loom stop signal of halt signal generator 22 according to picking mistake monitor, warp thread, stops the work of loom CD-ROM drive motor M, and makes electromagnetic braking mechanism 13 excitatory.The rotary encoder 23 that is connected with controlling organization C1 signal detects the loom rotational angle.
Revolution input mechanism 24 signals are connected on the controlling organization C1.Revolution input mechanism 24 is the revolutions that are used to import and set the loom when weaving.Controlling organization C1 stores the information by the setting revolution Ns of revolution input mechanism 24 inputs.Controlling organization C1 and revolution input mechanism 24, the revolution that is configured for grasping the revolution of loom is grasped mechanism.
Controlling organization C1, the braking control program that the flow chart of execution graph 2 illustrates.Below, the control based on the controlling organization C1 of flow chart shown in Figure 2 is described.
The power supply of loom is designed to be in ON (leading to) state.Controlling organization C1 waits for the input (step S1) based on the enabling signal of the ON operation that moves starting switch 20.When the input enabling signal, controlling organization C1 makes loom CD-ROM drive motor M work, thereby carries out the operation (step S2) of the loom under the setting revolution Ns that stores.That is, controlling organization C1, the work of control loom CD-ROM drive motor M makes main shaft 12 set the rotation of revolution Ns in the unit interval (1 minute).
After the loom CD-ROM drive motor M work, controlling organization C1 waits for the input (step S3) of loom stop signal.During the input of loom stop signal (at step S3, YES), controlling organization C1, the size of setting revolution Ns and benchmark revolution No compares (step S4).When setting revolution Ns when benchmark revolution No is following, controlling organization C1, only excitatory electromagnetic braking mechanism 13, and make the work of loom CD-ROM drive motor M stop (step S5).When setting revolution Ns when benchmark revolution No is above, controlling organization C1,19,13 liang of sides of excitatory electromagnetic braking mechanism, and make the work of loom CD-ROM drive motor M stop (step S6).
Whether controlling organization C1 is to select to make as electromagnetic braking mechanism 19 work of the 2nd arrestment mechanism when the work of loom CD-ROM drive motor M is stopped and making selection controlling organization as electromagnetic braking mechanism 13 work of the 1st arrestment mechanism.In this form of implementation, as the controlling organization C1 that selects controlling organization, stop in the action in the work of loom CD-ROM drive motor M, when the revolution of loom when benchmark revolution No is following, control and only make 19 work of electromagnetic braking mechanism.And controlling organization C1 stops in the action in the work of loom CD-ROM drive motor M, when the revolution of loom during greater than benchmark revolution No, controls two sides that make electromagnetic braking mechanism 19,13 and works.
The 1st form of implementation can obtain following effect.
(1-1) when the revolution Ns of the loom that utilizes revolution input mechanism 24 input when benchmark revolution No is following, have only 13 work (excitatory) of electromagnetic braking mechanism, loom CD-ROM drive motor M is subjected to the braking action of electromagnetic braking mechanism 13.As the revolution Ns of the loom that utilizes revolution input mechanism 24 input during greater than benchmark revolution (speed) No, the two sides work (excitatory) of electromagnetic braking mechanism 19,13, when loom CD-ROM drive motor M was subjected to the braking action of electromagnetic braking mechanism 13, main shaft 12 was subjected to the braking action of electromagnetic braking mechanism 19.When stopping the operation of loom under the low cruise state of the revolution Ns of so-called loom below benchmark revolution No, have only 13 work of electromagnetic braking mechanism.
When stopping the operation of loom under the low cruise state, even design is only braked loom CD-ROM drive motor M, between V-type band 16 and passive belt wheel 15, perhaps the slip between V-type band 16 and driving pulley 18 is also little.Again, when the operation of loom is stopped, even little brake force can carry out also that loom is out of service fast.That is the brake force when, the operation of loom being stopped is little.Therefore, when the operation of loom is stopped, as long as it is just enough to utilize the 13 pairs of loom CD-ROM drive motors M of electromagnetic braking mechanism to brake.When stopping the operation of loom under the low cruise state of the revolution Ns of so-called loom below benchmark revolution No, only make 13 work of electromagnetic braking mechanism, have the consumption of the Brake Energy that can avoid meaningless, and also can obtain the effect of necessary brake force.
When the operation of loom was stopped, reaching that loom is out of service fast must be big brake force.Therefore, when the operation of loom is stopped, must utilizing the 13 pairs of loom CD-ROM drive motors M of electromagnetic braking mechanism to brake and utilize 19 pairs of main shafts 12 of electromagnetic braking mechanism to brake.Make 13,19 liang of side's work of electromagnetic braking mechanism when under the high-speed cruising state of the revolution Ns of so-called loom, stopping the operation of loom, have the effect that obtains necessary brake force and stop the loom operation fast greater than benchmark revolution No.
(1-2) on the loom that earthquake load is big, generally be to use the driving force transmission mechanism that constitutes by V-type band and belt wheel that the driving force of loom CD-ROM drive motor M is passed to constituting of main shaft 12.This is to help making loom CD-ROM drive motor M work because allow the form of sliding slightly between V-type band and belt wheel.But when the operation of loom was stopped, if be designed to only loom CD-ROM drive motor M be braked, then between V-type band 16 and passive belt wheel 15, or the slip between V-type band 16 and the driving pulley 18 was excessive.Therefore, the situation that takes place that main shaft 12 sides can not stop fast or do not stop at the rotational angle of hope.In this form of implementation, when the operation of the loom under the high-speed cruising stops, because also work as the electromagnetic braking mechanism 19 of the 2nd arrestment mechanism, so, can avoid taking place aforementioned big slip.
(1-3) on the loom that Patent Document 1 is introduced, because utilize other electromagnetic brake of branch to brake, so main shaft might twist to the both ends of main shaft.In this form of implementation, because only to distolateral a braking of main shaft 12, so main shaft can not twist.
Below, the 2nd form of implementation of key diagram 3 and Fig. 4.Adopt same symbol with the same component part of the 1st form of implementation.
The 2nd form of implementation is that with the 1st form of implementation difference selector switch 25 signals are connected on the controlling organization C2.Whether selector switch 25 uses electromagnetic braking mechanism 19 when being selected at loom and stopping.Selector switch 25 can be operated to switch to and allow excitatory the allowing state and do not allow non-any state of allowing state that electromagnetic braking mechanism 19 is excitatory of electromagnetic braking mechanism 19.During the loom low cruise, selector switch 25 can be switched to the non-state of allowing.During the loom high-speed cruising, selector switch 25 can be switched to and allow state.
Selector switch 25 is in when allowing state, and permissive signal is transported to controlling organization C2.Selector switch 25 is in non-when allowing state, and permissive signal can not be transported to controlling organization C2.Controlling organization C2 judges according to the input of permissive signal that selector switch 25 is in and allows state.Controlling organization C2 when not having the permissive signal input, judges that selector switch 25 is in the non-state of allowing.Controlling organization C2 and selector switch 25, the selection controlling organization of selecting whether make 19 work of electromagnetic braking mechanism when being formed in the work that makes loom CD-ROM drive motor M and stopping and making 13 work of electromagnetic braking mechanism.
Revolution input mechanism 24 signals connect controlling organization C2.Controlling organization C2 stores the information by the setting revolution Ns of revolution input mechanism 24 inputs.
Controlling organization C2, the braking control program shown in the flow chart of execution graph 4.Below, the control based on the controlling organization C2 of the flow chart of Fig. 4 is described.
The power supply of loom is designed to be in the ON state.Controlling organization C2 waits for the input (step S11) based on the enabling signal of the ON operation that moves starting switch 20.When the input enabling signal, controlling organization C2 makes loom CD-ROM drive motor M work, thereby carries out the operation (step S12) of the loom under the setting revolution Ns that stores.That is, controlling organization C2, the work of control loom CD-ROM drive motor M makes main shaft 12 set the rotation of revolution Ns in the unit interval (1 minute).
After the loom CD-ROM drive motor M work, controlling organization C2 waits for the input (step S13) of loom stop signal.(at step S13, YES), controlling organization C2 judged whether selector switch 25 is in and allowed state (step S14) loom stop signal when input.Non-when allowing state when selecting switch 25 to be in, controlling organization C2, only excitatory electromagnetic braking mechanism 13, and make the work of loom CD-ROM drive motor M stop (step S15).When selecting switch 25 to be in to allow state, controlling organization C2,19,13 liang of sides of excitatory electromagnetic braking mechanism make the work of loom CD-ROM drive motor M stop (step S16) simultaneously.
In this form of implementation, the selection controlling organization that is made of controlling organization C2 and selector switch 25 stops in the action in the work of loom CD-ROM drive motor M, when the revolution of loom when benchmark revolution No is following, control and only make 19 work of electromagnetic braking mechanism.And this selects controlling organization, stops in the action in the work of loom CD-ROM drive motor M, when the revolution of loom during greater than benchmark revolution No, controls two sides that make electromagnetic braking mechanism 19,13 and works.
In the 2nd form of implementation, also can obtain the effect same with the 1st form of implementation.
The present invention also can have following form of implementation.
(1) in the 1st form of implementation, also can calculate the revolution of loom, and carry out the size comparison that the loom operation stops the revolution and the benchmark revolution No of loom before according to the rotational angle information that the rotary encoder 23 that detects usefulness from the loom rotational angle obtain.At this moment, the revolution of the loom before the loom operation stops only to make 13 work of electromagnetic braking mechanism when benchmark revolution No is following; The revolution of the loom before loom operation stops to work two sides of electromagnetic braking mechanism 13,19 during greater than benchmark revolution No.
