Description

Circle volume machine

Technical field

The present invention relates to the round volume machine that clutch designs simplification, the impact sound when making clutch reduce by half and jacquard weave can accurately be carried out (ト-ショ Application レ — ス Machine) of rotor metalwork (ロ- メ- Le) and rotor drive shaft.

Background technology

Circle volume machine, generally be to utilize a plurality of (64 that on the ring-type direction, are disposed, 94 even numbers such as grade) rotation of rotor metalwork (per 180 degree), when bobbin is turned round along circumferencial direction, the yarn assembly that pulls out from bobbin is arranged at the portion of beating up of ring center, is making style (decorative pattern), after beating up, by nip roll, sequentially be wound on the winding drum.

A plurality of rotor metalworks are superimposed to be fitted loosely on the rotor drive shaft, this rotor drive shaft has fitted loosely in the bottom that is arranged on the fixed axis of the predetermined quantity above the ring-type underframe of body itself by five equilibrium, by moving up and down of clutch, can make these rotor metalworks and rotor drive shaft clutch mutually.

In the device that solenoidoperated cluthes move up and down, the past is to adopt the jacquard device that uses the line version.That is, the perforated portion of the line version that the jacquard device connects according to operating member and not perforated (blind portion) and swing greatly or swing more by a small margin, being situated between, trailed wire comes moving up and down of solenoidoperated cluthes by the action of following this operating member.

So, the jacquard device is very big at the noise of operating member, mechanism's complexity of operating member in addition, and owing to reason present inventor such as also restricted on the number of line version has proposed new round volume machine, it utilizes the interaction energy of solenoid and spring the clutch of rotor metalwork and rotor drive shaft to be carried out the Switch Rotor metalwork of clutch.And proposed as the jacquard device, be not subjected to the round volume machine of new departure of line version restriction.(Japanese patent laid-open 9-176943 communique)

The related round volume machine of new departure comprises: the rotor metalwork is connected with rotor drive shaft, when moving downward, make the clutch and the supporting clutch of its separation, because of the effect of spring by the forked parts of the application of force downwards with penetrate the sliding axle that the backboard of forked parts can slide in the horizontal direction, and act on and be arranged on cam follower distolateral in the sliding axle and make make progress first cam of displacement of forked parts by sliding axle, in order to make cam follower enter into first action of cam zone, relying on the strength of spring on the one hand, is the solenoidal pulling force that utilizes action outside the first cam zone on the other hand.That is to say:, draw sliding axle so that cam follower leaves the mode in first action of cam zone when when solenoid is switched on; During no power, because the strength of spring makes it to enter in the first cam zone.Because first action of cam, the mobile clutch that makes of forked parts above-below direction carries out clutch.So,, just can control the rotation of rotor metalwork as long as each solenoid that is arranged on the rotor metalwork of control is switched on and non-energising.Like this, not only do not need jacquard device (ジャカ-De), the wire of the switching mechanism of connection jacquard device and each rotor metalwork and linkage component etc. are not wanted without exception yet, thereby make round volume machine overall simplification, and have realized the accuracy of operation.

Yet the round volume machine of new departure is to turn round to solenoid link electrical haulage sliding axle the time, so there is the problem that produces impact sound along with the slip of solenoid plunger (plunger) discontinuously.In addition, also exist when outside first action of cam zone, pushing back cam follower by solenoid pulling (plunger) unshakable in one's determination, though forked parts since the effect of spring downwards by the application of force, but only the elastic force of spring is not enough, it is unstable that the effect of each rotor metalwork becomes, thus the problem that jacquard weave is produced a very large impact.

Summary of the invention

In view of above each point, the purpose of this invention is to provide a kind of when the collision sound that produces when solenoid switched on is reduced by half, the novel round volume machine that jacquard weave can always be carried out exactly.

For reaching above-mentioned order, round volume machine involved in the present invention is characterised in that and is provided with: the rotor metalwork is connected with rotor drive shaft and makes the clutch that their separate when moving downward; Keep described clutch and applied the forked parts of power by the effect of spring downwards; Penetrate the backboard of described forked parts and the sliding axle that can slide in the horizontal direction; Act on and be arranged on the cam follower distolateral in the described sliding axle, being situated between makes make progress first cam of displacement of described forked parts by described sliding axle; For making described cam follower enter the solenoid that described sliding axle is pushed in described first action of cam zone; Described cam follower is pushed back extra-regional second cam of described first action of cam; Replenish the 3rd cam to the elastic force of the spring of the downward application of force of described forked parts; Structurally make cam follower enter into the action in the first action of cam zone by solenoid, and be provided with the cam that cam follower is moved outside the first action of cam zone, and then be provided with to replenish forked parts are applied the 3rd cam that the elastic force of the spring of power is used downwards.

So, according to round volume machine involved in the present invention, make cam follower enter the action in the first cam zone by solenoid, make cam follower leave the action in the first cam zone by second cam, thereby the clutch of rotor metalwork and rotor drive shaft is simplified.And, will be adjusted into solenoid energising and carry out when cam follower is in the summit of second cam, the impulsive sound when then switching on can reduce by half.And, because the down maneuver of forked parts is not only by the elastic force of spring, thereby is provided with the 3rd cam and carries out on one's own initiative in order to replenish its power, thereby, can reach the various good effect of carrying out jacquard weave etc. according to the jacquard weave program among the CPU of being input to exactly.

In addition, round volume machine involved in the present invention below the gear of described rotor drive shaft one, has formed described the 3rd cam, and it acts on above the extended projection in described forked parts backboard lower end.In this case, by second cam the cam follower back-pressure to the extra-regional moment of first action of cam, thereby Jie initiatively presses down forked parts by clutch positively separates the rotor metalwork with rotor drive shaft, owing to make the effect of rotor metalwork always very stable, thereby reach the optimum efficiency that jacquard weave is always accurately carried out.

In the drawings, the 1st, rotor metalwork (ロ- メ Le), it outwards is the extended scallop 1a of fan, 1a symmetrically and forms at the lower end and the equidirectional extended

calvus

3,3 of

scallop

1a, 1a of quill shaft 2 by quill shaft 2 with in the upper end of quill shaft 2.

Rotor metalwork 1 rotatably fits loosely in the top (shown in Figure 2) of uniformly-spaced upright a plurality of (64,94 etc. even number) fixed axis 5 of establishing above the ring-type underframe 4 that constitutes the M of body own in the horizontal direction.Rotor drive shaft 6 rotatably fits loosely in the bottom of fixed axis 5 in the horizontal direction.In other words, rotor drive shaft 6 fits loosely in the lower rotor metalwork of fixed axis 5 in the mode of folding rotor metalwork 1 on top.

The scallop 1a of

rotor metalwork

1,1a can rotate in the circular hole 4`` (circular portion of adjacency is overlapped) that is provided with continuously on the ring-type direction of the ring-type upper frame 4 ' of parallel device above ring-type underframe 4 coaxial.

Rotor drive shaft 6 is configured to can one rotate with the gear 7 of lower end, and the gear of gear 7 and adjacency is implicative of each other.So if in the gear 7 one is subjected to from the power of main shaft through driven wheel 8 and rotates, 6 of all rotor drive shafts are subjected to the rotation transmission of mutual both forward and reverse directions.Rotor metalwork 1 is made as even number also just because of this reason with rotor drive shaft 6.

Clutch 9 is entrenched in the axial region of rotor drive shaft 6, the axial region of rotor drive shaft 6 as shown in Figure 3, it is non-circular that section shape is, the section shape in interior week and its same clutch 9 can slide in the axial direction, but can not rotate (fixing) on direction of rotation.

The

projection

10,10 that opposed locations being provided with on clutch 9 can fasten with the

calvus

3,3 that is contained in rotor metalwork 1 lower end.In addition, the outer peripheral face undercut at this clutch 9 goes out annular recess 11.Become the extended cantilever sheet of forked 12a to be fastened in this annular recess 11 from the facies ventralis of the backboard 12c of forked parts 12.

Forked parts 12 be fixed on that Jie can be slided in vertical direction by the dorsal part bulk 12d of portion of its backboard 12c and the axle 13 of break-through ring-type underframe 4 and ring-type upper frame 4 ' on.In other words, forked parts 12 can slide in vertical direction through axle 13.

In addition, forked parts 12 are always applied power downwards by means of the effect of dorsal part bulk 12d of portion that is installed in its backboard 12c and the spring 13a between the ring-type top box 4 '.That is,, then have the also action downwards thereupon of clutch 9 of the annular recess 11 of this cantilever sheet 12a engaging as the action downwards of forked parts 12 with the effect of spring 13a.The

projection

10,10 above the clutch 9 and the calvus of rotor metalwork 1 left in 3,3 minutes.(not acting on)

At the upper unit of forked parts 12 become the U shape to stride across cap (キャ Star プ portion) 12b quill shaft 2, outstanding of rotor metalwork 1.Below cap 12b, be provided with groove 12b '.Groove 12b ' when the action downwards of forked parts 12, is stuck close on the

calvus

3,3 of rotor metalwork 1 in the mode that is covered as previously mentioned.Promptly, thereby the

projection

10,10 above the downward action of the forked parts clutch 9 is left from the

calvus

3,3 of rotor metalwork 1, (synchronization) simultaneously, the groove 12b ' of the cap 12b of forked parts 12 is fastened on the calvus 3, therefore, can make rotor metalwork 1 rotate accurately, stop with per 180 degree.

At the dorsal part bulk portion 12d place of the backboard 12c of forked parts 12, be provided with the sliding axle 14 of the break-through that can slide in the horizontal direction.The cam follower 14a that acts on the cam disc 15 top formed first cam 15a that are entrenched in rotor drive shaft 6 axial regions is supported by axle the interior distolateral of sliding axle 14 with rotating freely.On cam disc 15, except the first top cam 15a, on periphery returning apparatus the second cam 15b.That is, the first cam 15a makes cam follower 14a carry out knee-action, and the second cam 15b makes cam follower 14a carry out the sliding motion of circumferencial direction.

Be provided with the slotted hole 14b that penetrates top and bottom on sliding axle 14, axle 13 vertically passes slotted hole 14b.So sliding axle 14 is not subjected to the influence of axle 13 knee-actions (knee-actions of forked parts 12), can slide in the horizontal direction.

Thereby cam follower 14a enters the zone of action of first cam 15a by the rear end face of solenoid 16 pushing sliding axles 14.In addition, owing to be arranged on the effect of the second cam 15b of the circumferencial direction of cam disc 15, cam follower 14a is pushed to outside the zone of action of the first cam 15a.

Plunger (プラ Application ジャ) 16a is vertically disposing solenoid 16 highlightedly when energising.Thereby the leading section 16b of plunger 16a is situated between and is bearing on the ring-type underframe 4 top upright frames of establishing by axle by pin 17 '.The dorsal part rank 18b of portion of the rotation control rod 18 that pushing is vertically rotated, like this, the mouth 18a of rotation control rod 18 pushes the rear end face of sliding axle 14.That is, because of the action of solenoid 16, rotation control rod 18 as shown in Figure 2 chain-dotted line and solid line shown in carry out displacement.And, though do not illustrate, also can pass through the leading section 16b of the plunger 16a of solenoid 16, directly push the rear end face of sliding axle 14.

According to the jacquard weave program that is input among the no illustrated CPU, give solenoid 16 energisings, owing to inwardly advance sliding axle 14, cause cam follower 14a to act on first cam 15a of cam disc 15, the upwards action of forked thus parts 12, by clutch 9, rotor metalwork 1 is connected with rotor drive shaft 6 and rotates.On the other hand, solenoid 16 (discharges plunger 16a) under non-power status, because of the effect of second cam 15b overlapping on the distolateral cam follower 14a end face within it, sliding axle 14a is back into outside the zone of action of the first cam 15a (not acting on) forcibly.And, be in moment on summit of the circumferencial direction of second cam at cam follower 14a, solenoid 16 is switched on.

As previously mentioned, solenoid 16 is when no power, because the effect of the second cam 15b, when cam follower 14a is pushed outside the zone of action of getting back to the first cam 15a, when being urged downwardly because of the forked parts 12 of the effect of spring 13a, clutch 9 is moved downwards, and

projection

10,10 above it and the calvus of

rotor metalwork

13,3 break away from.In this moment, rotor metalwork 1 will begin rotation, and since the groove 12b ' of the cap 12b of forked parts 12 engage with the

calvus

3,3 of rotor metalwork 1 at once, rotor metalwork 1 is from before this rotation (during solenoid 16 energisings), just stopped rapidly just having rotated 180 places of spending.

Below the gear 7 that the lower end of rotor drive shaft 6 is provided with being integral, formed the 3rd cam 19.The 3rd cam 19 acts on lower end from the backboard 12c of forked parts 12 downwards above rotor drive shaft 6 extended projections 20.That is, solenoid 16 is when no power, and the second cam 15b back into cam follower 14a outside the zone of action of the first cam 15a, carves at this moment, and the 3rd cam 19 has the function of additional forked parts 12 by the downward thrust of the elastic force generation of spring 13a.In other words, push away forked parts 12 under 19 actives of the 3rd cam.This is that forked parts 12 may can not react really because only with the elastic force of spring 13a, according to the jacquard weave program among the input CPU, the entanglement that produces in the jacquard weave is eliminated in rudiment.

In a word, according to the jacquard weave program that is input among the no illustrated CPU, control is to being located at the energising of the solenoid 16 on each rotor metalwork, thus, can freely control the operation in the circular hole 4`` that is provided with continuously along the ring-type of ring-type upper frame 4 ' of the bobbin (not having diagram) that brought by rotor metalwork 1 and rotor drive shaft 6 clutches, and can be without limits and to make desired jacquard weave exactly next.

In addition, though in above-mentioned form of implementation, do not do special explanation, but the first cam 15a and the second cam 15b have constituted single part (cam disc 15), if the 3rd cam 19 and rotor drive shaft 6 one are formed on the gear 7 of one rotation, because the minimizing of number of components can realize reducing cost.

And, to above-mentioned form of implementation, between sliding axle 14 and solenoid 16, rotation control rod 18 has been installed to the sliding axle 14 pushing application of forces, this vertically is provided with solenoid 16 as shown in figure for correspondence, has saved the space so effectively.
