Background technology
In recent years, along with to the increasing and the rationalization of the enterprise operation that the brisk market depression is impelled of energy problem's care degree, developing energetically energy-conservationization and reduction are being manufactured the household electronic products that instinct is made very big contribution.For example, energy-conservationization and reduction manufacturing cost aspect at present national universal washing machine have been sent in very big hope.
Yet, in the past in the washing machine body of (comprising the automatic washing machine of being with drying machine), be provided with the swing roller taking-up that is positioned at washing machine inside and put into the clothing class conveying end that the clothing class is used, in this swing roller, be provided with in swing roller, to take out and put into the cylinder input port that the clothing class is used.After laundry finishes, in order to take out the clothing class that is contained in the swing roller, must make the clothing class conveying end of washing machine body and the cylinder input port of swing roller be in certain relativity position relation, swing roller is in case stop at after the assigned position with the position of this relativity relation, from the viewpoint of safety, must prevent to rely on the rotation of the caused swing roller of inclined to one side load that a side causes because of the clothing class.
In order to address this problem, proposed reliably swing roller to be locked after the laundry multiple technologies motion (for example, with reference to Japanese documentation 1) of usefulness.Figure 16 is the side sectional view of the washing machine in the invention shown in the expression Japanese documentation 1, and this invention is the clothing time-like in taking-up is contained in swing roller, stops by the rotation condition of mechanical controlling organization with swing roller.Below further do concrete explanation.
Among Figure 16, the washing machine in the invention shown in the Japanese documentation 1 has: can be around the swing roller in horizontal rotational shaft is arranged on body 1 freely 4; Be arranged on the cylinder input port (not shown) of all sides of this swing roller 4; And be arranged on clothing class conveying end 32 above the body 1, disk 21 with chimeric recess 24 links shape ground with swing roller 4 and is provided with, setting has the chimeric bar 25 of fitting projection 26, this fitting projection 26 and described chimeric recess 24 are chimeric, and swing roller 4 constraints are stopped.Adopt this structure, when laundry (drying) finishes, fitting projection 26 and chimeric recess 24 are chimeric, the cylinder input port of swing roller 4 is aimed at the clothing class conveying end 32 of body 1, swing roller 4 is stopped, on this position, swing roller 4 constraints are stopped, the clothing class that is contained in the swing roller 4 can being taken out safely by cylinder input port and clothing class conveying end 32.
Invention shown in the Japanese documentation 1, with chimeric recess 24 and fitting projection 26 when chimeric, employing be above-mentioned the sort of mechanical controlling organization.That is, employing is following a kind of mechanical controlling organization.Laundry finishes back (swing roller 4 stops the back), be pushed in fitting projection 26 and make the rotation of swing roller 4 (disk 21) dead slow speed under the state of disk 21 side faces chimeric bar 25, when the chimeric recess 24 of disk 21 rotates to the fitting projection 26 of chimeric bar 25, will inevitably form chimerism, swing roller 4 constraints stopped under cylinder input port and the state that clothing class conveying end 32 is aimed at.
In recent years, also proposing following a kind of motion of doing washing the leading controlling organization of pusher side is, carries out position probing at the laundry pusher side, make swing roller 4 stop at assigned position in advance, the electric motor units of cylinder locking is carried out in startup then, swing roller is retrained fully stop.For example, can list device shown in Figure 17 as making swing roller 4 stop at the device of assigned position in advance.
Among Figure 17, around disk 21 or local, the Hall IC unit of being made up of 3 Hall IC 51 is set, detect by the position signalling of spending every electrical angle 60 from terminal 51a, 51b, 51c, position to swing roller 4 is detected, and can make swing roller 4 stop at the position of regulation.Like this, in the occasion that adopts the leading controlling organization of this laundry pusher side, in order to detect the relativity position relation of swing roller 4 and the electric motor units of carrying out the cylinder locking, the position sensor of Hall IC unit etc. need be set, the position to swing roller 4 monitors all the time.
[patent documentation 1] Japanese patent laid-open 9-122374 communique (paragraph 0024, Fig. 3)
Yet, in order to carry out cylinder locking, when chimeric, if adopt above-mentioned the sort of controlling organization, there are following problem in chimeric recess 24 and fitting projection 26.
At first, in the mechanical controlling organization shown in the Japanese documentation 1, detect the rotation that swing roller 4 is detected in the loop by rotating speed in the washing machine use, when after swing roller 4 stops, detecting rotating speed and being 0, be pushed in fitting projection 26 under the state of disk 21 side faces and make the rotation of swing roller 4 (disk 21) dead slow speed chimeric bar 25.And, in the way of dead slow speed rotation, formed the chimerism of fitting projection 26 with chimeric recess 24, even but just formed after the chimerism, detecting rotating speed in rotating speed detection loop is before 0, make swing roller 4 rotations because of wanting to break away from this chimerism, will cause excessive load, exist the problem of damaging these mechanisms drum drive motor 22, disk 21, chimeric bar 25 and other peripheral plane structure (for example plunger 27, spring 29 etc.) of swing roller 4.
In addition, want not damage these mechanisms and form chimerism at assigned position, the position sensor of above-mentioned the sort of Hall IC unit etc. then must be set, all the time the position that monitors swing roller 4 is controlled, but this moment, in order to make the semiconductor element performance function of Hall IC etc., need a lot of indispensable electronic loop elements of assembling, by the relativity position relation of swing roller 4 with the electric motor units of carrying out the cylinder locking detected, all the time monitor the position of swing roller 4, so exist the problem that increases number of components and increase electric power and consume.
And, because the sensor of detection swing roller 4 positions is a split-type structural with the stopper element of chimeric bar 25 grades of the cylinder locking of carrying out this swing roller 4, therefore, the problem that exists is at the signal that is sent to stopper element from sensor and is sent to from stopper element the transmission way of signal of sensor, noise etc. can take place, and makes stopper element produce misoperation.
For this reason, the inventor has considered the semiconductor element of a kind of Hall IC of not using high price etc. and by implementing easily and cheap mechanical type controlling organization, can carry out the rotary body controlling organization of position probing to rotation.
In view of this point, the object of the invention is, the control method that following a kind of rotary body controlling organization, rotary body control module and rotary body thereof be provided promptly, stop for the rotation condition with rotary body, even adopt the mechanical type controlling organization, the problem that cost rises and power consumption increases that is produced in its controlling organization that does not use the washing machine of the semiconductor elements such as Hall IC of relevant position probing to dominate, also can be rotated the position probing of body, can carry out the cylinder locking reliably.
Summary of the invention
In order to solve above-mentioned problem, the invention is characterized in, be provided with and the abutting part of block butt and the holding section that engages with block, in that being engaged with the holding section, block makes on the rotary body constraint assigned position before stopping, when block arrives abutting part, the position detection signal of the position of output expression rotary body and block.
Again specifically, the invention provides following scheme.
(1) a kind of rotary body controlling organization, comprise: the rotary body that is formed with the holding section on the circumferencial direction, and the rotary body control module that is provided with the block that described rotary body constraint is stopped, during the relative shape with described block of described rotary body is rotated, this block engages with described holding section, this rotary body constraint is stopped, it is characterized in that, on described rotary body, the two ends of its holding section are formed with described block butt, the abutting part that size is set greatlyyer than the radius of turn of this rotary body, and, in described rotary body control module, be provided with the 1st output device of output connection signal when described block is in the state opposite with its holddown, the relative shape with described block of described rotary body is rotated, when this block arrives described abutting part, from described the 1st output device output connection signal.
According to one embodiment of the invention, the rotary body controlling organization has: the rotary body that is formed with holding section that forms on the circumferencial direction and the abutting part that forms at the two ends of this holding section along its periphery;
And be provided with block, this block that the constraint of this rotary body is stopped usefulness because of the external force of the obstacle that becomes this braking function of performance, export the rotary body control module of the 1st output device of connection signal when being in the state opposite with its holddown,
Thus, when rotary body with the circumference of the roughly same radius of the radius of turn of rotary body on when relatively being rotated with block, set greatlyyer abutting part (being located at the abutting part of rotary body ledge) in size than the radius of turn of this rotary body, block and rotary body butt, rely on this effect to make external force act on block, become the state opposite with block, detect the 1st output device output connection signal of this state, can concern the position of the relativity of rotary body and block according to this connection signal and detect.
Promptly, in the past for the position relation of the relativity that detects rotary body and block, its method is that position sensors such as Hall IC are set, all the time the position to rotary body monitors, but in the present embodiment, relies on the interaction of rotary body and block, when arriving a certain ad-hoc location, rotary body catches the variation of block, its variation is transformed into electric signal, only needs to utilize the detection of above this momentary electric signal, just can concern and detect the relativity position of rotary body and block.Like this, rely on the mutual mechanical effect of rotary body and block, can reduce required member number and the member expense of monitoring, can reduce production costs, and, only need the detection of momentary electric signal, can avoid the waste of power consumption, energy-conservation turning into contribution.
In this example, rotary body is rotated with block " relatively ", but comprises that also rotary body and block slip the occasion that is rotated and the field that is rotated under the gapped state is being set between rotary body and block.Slip the occasion that is rotated at rotary body and block, rotary body is also accepted the rotation inhibitory action from block, worry causes the deterioration of rotary body and block because of the wearing and tearing of rotary body and block, but the occasion that is rotated under the gapped state is being set between rotary body and block, because of the butt of the abutting part of block and rotary body only in a flash, so can prevent the wearing and tearing deterioration of rotary body and block, and then can prevent following shortcoming promptly, because of the wearing and tearing of block leading section, as detecting that decline takes place for the sensitivity of function of switch that block arrives the abutting part of rotary body and life-span of shortening switch.In addition, slip the occasion that is rotated at rotary body and block, when worrying the rotary body action, might cause the misoperation of the switching function of block because of vibration, but carry out relative the rotation under the gapped state by being provided with between rotary body and block, can prevent this misoperation, realize the stabilisation of switching function.
With the abutting part of block butt, be configured to greatlyyer than the radius of turn of rotary body, as long as be convexly equipped with, no matter be where and shape from rotary body.For example,, also can make the shape of band circular arc,, also have the scalariform of abundant height in order to improve the reliability of cylinder locking in order to reduce the wearing and tearing of block more.Like this, by setting in advance the part (abutting part) that is convexly equipped with from rotary body, this abutting part can impel the block state variation, can be used as trigger performance function, makes block become the state opposite with its holddown.
In addition, adopt this abutting part, the wearing and tearing that solved block prevent this opposite technical problem of reliability that the constraint with rotary body stops.That is, if want more reliably the rotary body constraint is stopped, because of need be with block with the bigger side face of trying hard to recommend to rotary body, so can impel the wearing and tearing deterioration more.And on the other hand,, then must under with the slight state of contact of the side face of block and rotary body, make the rotation of rotary body dead slow speed, so the reliability that the constraint of rotary body stops shortcoming if want to avoid the wearing and tearing deterioration of block.For this reason, by abutting part is set on rotary body, when not being in fastening state, not to block and the powerful pushing of rotary body, can prevent the wearing and tearing deterioration of stop block, and when being in fastening state, the position of rotary body and block concerns that (the position relation of the radius of turn direction of rotary body) correspondingly reduced the size that is convexly equipped with from rotary body, can realize the reliability that the constraint of rotary body stops, so can solve the problem of the reliability shortcoming that the constraint of the wearing and tearing deterioration of chimeric member and rotary body stops.
" state opposite with its holddown " is meant the state that has carried out action with the opposite states ground that suppresses the block action.Again specifically, outstanding and block is moved under the complete repressed state at block from the rotary body control module, the result of external force effect, the state after the direction that block breaks away from from the holding section is moved promptly, the state after moving on the contrary with its holddown.For example, helical spring, also can utilize the reset force of coil total length towards the prolonging direction effect, be held in the holddown of block in advance, transfer to above-mentioned inverse state when the total length of the coil that causes when the action of block is shunk, in addition, also can utilize the diameter that makes coil to become the reset force that acts on like that greatly, be held in the holddown of block in advance, transfer to above-mentioned inverse state when the coil diameter that causes when the action of block reduces, its construction form is not limited.
(2) the rotary body controlling organization is characterised in that, when described block arrives described abutting part, and described rotary body rotation ormal weight, this block engages with described holding section, and this rotary body constraint is stopped.
According to one embodiment of the invention, be formed with along its periphery in the rotary body of abutting part and holding section, by preestablishing and abutting part position relation (air line distance, circumference, angle of circumference etc.) corresponding ormal weight with the holding section, when block arrives abutting part, by making rotary body rotation ormal weight, opposability moves to the position that block can engage with the holding section of rotary body, engages, rotary body is retrained the positioning control that stops a kind of like this rotary body with the holding section so can realize block.
Promptly, when block arrives abutting part, utilize the invention of above-mentioned (1), from the 1st output device output connection signal, by detecting this connection signal, can detect rotary body and arrive a certain certain location, can realize only need making rotary body to rotate predefined ormal weight from this certain location can such positioning control.
Therefore, the rotary body that is used to stop from the rotation condition with rotary body suppresses the position detection signal of the 1st output device of unit, the relativity position relation that rotary body and rotary body is suppressed the block of unit detects, and rotary body can be stopped at assigned position.

[electrical structure of rotary body control module]
Figure 11 is the loop diagram of the electrical structure of the rotary body control module 105 of expression embodiments of the invention.
Among Figure 11, being provided with decontrol in rotary body control module 105 is cam drive motor 114, the application of force of helical spring 107 can be removed, block 106 is moved from the direction that swing roller 102 breaks away from, this cam drive is connected with terminal 113c with an end of motor 114, and cam drive is connected with an end of terminal 113e and switch 109 with the other end of motor 114.One end of switch 109 is connected with terminal 113d, and the other end of switch 109 is connected with terminal 113d.In addition, an end of switch 108 is connected with terminal 113a, and the other end of switch 108 is connected with terminal 113b.
[time diagram]
Figure 12 is the operating position of expression block 106 and the time diagram of the electric signal relation of being exported by switch 108 and switch 109.
Among Figure 12, epimere represents that the electric signal of the output of switch 109 is represented in the stage casing by the electric signal of switch 108 outputs, and hypomere is represented the operating position of block 106.The operating position of the block of representing for hypomere 106, the states of drawing in to greatest extent in the rotary body control module 105 are minimum of a values, are maximums from rotary body control module 105 outstanding states to greatest extent.
At first, block 106 utilizes the reset force of helical spring 107, begins from rotary body control module 105 outstanding.At this moment, because of the protuberance of the movable contact pin 109a of switch 109 is positioned at the recess 110a of hypomere cam 110, so switch 109 is maintained at off-state.On the other hand, because block 106 is not the state of giving prominence to from rotary body control module 105 to greatest extent, so switch 108 is on-state (region D
1: released state).
Secondly, block 106 utilizes the reset force of helical spring 107 and more outstanding, is moving after the ormal weight, and switch 109 is transferred to on-state from off-state.Again specifically, as shown in Figure 8, by contact condition from the part of the recess 110a of the protuberance of movable contact pin 109a and hypomere cam 110, transfer to the protuberance of movable contact pin 109a and hypomere cam 110 recess 110a beyond the contact condition of part, switch 109 is transferred to on-state.On the other hand, because block 106 is not the state of giving prominence to from rotary body control module 105 to greatest extent, so switch 108 is on-state (region D
2: the stage of state before released state → locking).
Then, when block 106 utilized the reset force of helical spring 107 to become to greatest extent outstanding state, switch 108 was transferred to off-state from on-state.Again specifically, break away from from fixed tabs 108b, make switch 108 transfer to off-state by the movable contact pin 108a of the switch 108 that is pushed into fixed tabs 108b up to now from the effect of block 106.On the other hand, because the part state of contact in addition of the protuberance of the movable contact pin 109a of switch 109 and the recess 110a of hypomere cam 110 do not change, so switch 109 still is an on-state (region D
3: state before the locking).
Moreover, when swing roller 102 and block 106 were relative, abutting part 104 butts that form on this block 106 and the swing roller 102 relied on this effect to make external force act on block 106, when block 106 became the state opposite with holddown, switch 108 was transferred to on-state from off-state.Again specifically, in region D
3In, the movable contact pin 108a of the switch 108 that has broken away from from fixed tabs 108b relies on from the effect that is pushed into the block 106 in the rotary body control module 105, is urged to fixed tabs 108b again, and switch 108 is transferred to on-state from off-state.On the other hand, because the part state of contact in addition of the protuberance of the movable contact pin 109a of switch 109 and the recess 110a of hypomere cam 110 do not change, so switch 109 still is an on-state (region D
4: lock ready state).
At last, in region D
4In, detecting expression switch 109 is after the electric signal of on-state, stops behind the swing roller 102 rotation ormal weights, the holding section 103 of swing roller 102 engages with block 106.At this moment, switch 109 still is an on-state.Block 106 utilizes the helical spring application of force to engage with holding section 103, so switch 108 becomes off-state (region D once more
5).
Using cam drive with motor 114 block 106 to be drawn in occasion in the rotary body control module 105, the electric signal when switch 109 is become off-state (cut-off signal) detects, and can hold the stop position of drawing in of block 106.In the above description, what represent is that block 106 is in outstanding to greatest extent state, block 106 is keeping the contactless state with swing roller 102, swing roller 102 is in the state (state before the locking) that dead slow speed is rotated with block 106 relative shape ground, but among the present invention, block 106 can not be to greatest extent highlightedly with the periphery state of contact of swing roller 102 under, swing roller 102 keeps slipping with block 106 and is relative, and swing roller 102 also carries out the dead slow speed rotation slidably with block 106.In this occasion, the switch 108 among Fig. 6 needs to have play, even block 106 is not outstanding to greatest extent state, switch 108 is also disconnected.
[flow process of action]
Figure 13 is the concrete action flow chart of the rotary body controlling organization of expression embodiments of the invention.
Among Figure 13, at first be to make swing roller 102 be in released state (step S131).Again specifically, block 106 is in the state that is drawn into rotary body control module 105 to greatest extent.At this moment, switch 109 becomes off-state, and switch 108 becomes on-state.Like this, the epigyny device of rotary body control module 105 (for example washing machine), by moving while discerning this signal condition, in the high speed rotation of swing roller 102, make block 106 and abutting part butt, a kind of like this misoperation of stop block 106 breakages can be prevented, and then the stability of spinning movement can be increased.
Secondly, the high speed of swing roller 102 rotation (for example laundry) finishes, and swing roller 102 stops (step S132) temporarily.Thus, utilize the function of the rotary body controlling organization of embodiments of the invention, the constraint of carrying out swing roller 102 stops (step S133～step S139).
At first, block 106 is from rotary body control module 105 outstanding (step S133).Again specifically, with motor 114 supply capabilities, as shown in Figure 9 rotary power is passed to epimere cam 111 to cam drive.And, along with the spinning movement of epimere cam 111, be that the center is rotated action with the central shaft of epimere cam 111 by jut 111a, the block 106 that is connected with jut 111a is outstanding from rotary body control module 105.
At this moment, during till the protuberance of the movable contact pin 109a of switch 109 is outstanding from the recess 110a of hypomere cam 110, utilize the rotary power of cam drive with motor 114, with the protuberance of this movable contact pin 109a after the recess 110a of hypomere cam 110 is outstanding, also can utilize the reset force of helical spring 107 to make block 106 outstanding etc., the reset force that can effectively utilize helical spring 107 makes block 106 outstanding.
Then, after block 106 arrives the position that can give prominence to, whether the connection signal of expression switch 108 conducting states exported detected (step S134).When the connection signal of expression switch 108 conducting states is not exported, as the region D of Figure 12
3Shown in, block 106 is in to greatest extent outstanding state, just as yet not with abutting part 104 butts of swing roller 102, like this, in this occasion, before the connection signal of output expression switch 108 conducting states, swing roller 102 carries out dead slow speed rotation (step S135) in a circumferential direction.
Then, whether the connection signal of expression switch 108 conducting states has been exported detected (step S136).When this connection signal is not exported as yet, return step S135 and proceed the dead slow speed rotation.On the other hand, when having exported this connection signal, during abutting part 104 butts of block 106 and swing roller 102, by making swing roller 102 rotations (step S137) from this position with ormal weight, block 106 utilizes the reset force of helical spring 107 to engage with the holding section 103 of swing roller 102, swing roller 102 constraints can be stopped.The aspect that is rotated with ormal weight about the swing roller among the step S137 102 is with reference to Figure 14 aftermentioned.
On the other hand, in above-mentioned step S134, when the connection signal of expression switch 108 conducting states has been exported, abutting part 104 butts of block 106 and swing roller 102.Like this, in this occasion, make swing roller 102 rotations (step S138) from this position with ormal weight.The aspect that is rotated with ormal weight about the swing roller among the step S138 102 is also with above-mentioned the same as Figure 14 aftermentioned.
Secondly, after the spinning movement of step S138 finishes, to swing roller 102 locked detection the (step S139) whether.Again specifically, for example make swing roller 102 carry out small rotation, and swing roller 102 is complete when motionless, utilize the reset force of helical spring 107 that block 106 is engaged with the holding section 103 of swing roller 102, thereby the constraint that finishes swing roller 102 stops.
On the other hand, among this step S139, make swing roller 102 carry out small rotation, and swing roller 102 is smoothly during rotation, as can be seen, be to rotate with having on the opposite direction that makes the holding section 103 that swing roller 102 constraint stops with the block 106 of abutting part 104 butts.
In this occasion, processing is returned to carry out tumbler lock on the basis of step S135 fixed.That is, make swing roller 102 continue dead slow speeds rotations (step S135), whether the connection signal of normality being represented the conducting state of switch 108 has been exported and has been detected (step S136).When this connection signal had been exported, by making swing roller 102 rotations (step S137) from this position with ormal weight, the constraint that finishes swing roller 102 stopped.
Adopt the action of above explanation, use the leading controlling organization of washing machine that increases associated semiconductor element with cost, also can prevent to carry out the shortening life-span of the block 106 of cylinder locking, can carry out the cylinder locking in reliability ground although adopt.
[the ormal weight rotation of swing roller]
The figure that Position Control when Figure 14 rotates with ormal weight for explanation swing roller 102 is used.
Figure 14 is the state diagram that is in a plurality of positions for the ease of expression rotary body control module 105.Rotary body control module 105a and swing roller 102 are opposed, be in from the holding section positions (the 33rd utmost point) that 103 center (the 0th utmost point) rotates 330 degree in the counterclockwise direction, rotary body control module 105b and swing roller 102 are opposed, be in from the holding section positions (the 34th utmost point) that 103 center rotates 340 degree in the counterclockwise direction, rotary body control module 105c and swing roller 102 are opposed, be in from the holding section positions (the 35th utmost point) that 103 center rotates 350 degree in the counterclockwise direction, rotary body controls single 105d and swing roller 102 is opposed, is in the position (36=the 0th utmost point) of revolving three-sixth turn from the center of holding section 103 in the counterclockwise direction.
In step S134 shown in Figure 13, when the connection signal of the conducting state of switch 108 was not represented in output, block 106 was in outstanding to greatest extent state.That is, rotary body control module 105 for example is in the position of 105a or the position of 105b.When swing roller 102 is rotated in a clockwise direction when making block 106 with abutting part 104 butts, if make swing roller 102 be rotated in a clockwise direction (above-mentioned step S137) again with 10 degree (1 is greatly little), then rotary body control module 105 relativities move to the position of 105a, block 106 and abutting part 103 butts.Suppose that swing roller 102 rotates in the counterclockwise direction, the occasion of block 106 and abutting part 104 butts, if make swing roller 102 rotate (above-mentioned step S137) in the counterclockwise direction again with 10 degree (1 is greatly little), then rotary body control module 105 relativities move to the position of 105a, and block 106 engages with holding section 103.Like this, said among the step S137 shown in Figure 13 " ormal weight " is exactly the meaning of the anglec of rotation 10 degree in an embodiment of the present invention.About the anglec of rotation, different because of the stepper motor that drives swing roller 102, can be any anglec of rotation, for example be rotated etc. every the anglec of rotation 5 degree.
In step S134 shown in Figure 13, when having exported the connection signal of expression switch 108 conducting states, block 106 becomes the butt state with abutting part 104.That is, rotary body control module 105 for example is in the position of 105c.At this moment, if make swing roller 102 with ormal weight (anglec of rotation 10 degree) rotation (above-mentioned step S138), then rotary body control module 105 relativities move to the position of 105d or the position of 105b.As mentioned above, carry out, when rotary body control module 105 is in the position of 105d, stop with regard to the constraint of the swing roller 102 that is through with to the swing roller 102 locked step that detects (step S139) whether.On the other hand, when rotary body control module 105 is in the position of 105b, swing roller 102 is still in smooth rotation, so continue to carry out dead slow speed rotation (step S135) in the counterclockwise direction, normality is represented whether the connection signal of switch 108 conducting states has been exported and detected (poly-S136 of step), when having exported this connection signal, by making swing roller 102 rotate (step S137) in the counterclockwise direction from this position with ormal weight (anglec of rotation 10 degree), can make rotary body control module 105 relativities move to the position of 105d, swing roller 102 constraints can be stopped.
[variation]
Figure 15 is the flow chart of the concrete action variation of the rotary body controlling organization of expression embodiments of the invention.
Among Figure 15, each from step S151 to step S155 handled and adopted the above-mentioned identical to the processing of step S135 from step S131 of Figure 13, Therefore, omited explanation.
In step S155, normality is represented whether the connection signal of switch 108 conducting states has been exported detect, when not exporting this connection signal, return step S155 and proceed the dead slow speed rotation.On the other hand, when having exported this connection signal, promptly, in the occasion of block 106 with abutting part 104 butts of swing roller 102, in case the rotation of swing roller 102 stops, use cam drive with motor 114 block 106 to be drawn in rotary body control module 105, swing roller 102 becomes released state (step S157).
Secondly, by making swing roller 102 rotations (step S158) with ormal weight (anglec of rotation 10 degree), can make block 106 relativities move to the position relative with the holding section 103 of swing roller 102 from this stop position.
Then, after block 106 relativities move to its relative position, utilize cam drive with motor 114,, block 106 is engaged with holding section 103 by slowly and by stages giving prominence to (step S159) from rotary body control module 105 with making block 106 being connected of epimere cam 111.
In step S154 shown in Figure 15, when having exported the connection signal of expression switch 108 conducting states, block 106 becomes the butt state with abutting part 104.That is, rotary body control module 105 for example is in the position (with reference to Figure 14) of 105b.In this occasion, in case the rotation of swing roller 102 stops, using cam drive block 106 to be drawn in rotary body control module 105 with motor 114, swing roller 102 becomes released state (step S160).
Secondly, by making swing roller 102 rotations (step S161) with ormal weight (anglec of rotation 10 degree), can make block 106 relativities move to the position relative with the holding section 103 of swing roller 102 from this stop position.
Then, after block 106 relativities move to this relative position, utilize cam drive with motor 114,, block 106 is engaged with holding section 103 by slowly and by stages giving prominence to (step S162) from rotary body control module 105 with making block 106 being connected of epimere cam 111.
Moreover, after the outstanding release of step S162, to swing roller 102 locked detection the (step S163) whether.Again specifically, for example make swing roller 102 carry out small rotation and swing roller 102 is complete when motionless, utilize the reset force of helical spring 107 that block 106 is engaged with the holding section 103 of swing roller 102, the constraint that finishes swing roller 102 stops.
On the other hand, among this step S163, make swing roller 102 carry out small rotation and swing roller 102 smoothly during rotation, as can be seen, with the block 106 of abutting part 104 butts be with have the side that makes the holding section 103 that swing roller 102 constraints stop and being rotated in the opposite direction.
In this occasion, processing is returned to carry out tumbler lock on the basis of step S155 fixed.That is, make swing roller 102 continue dead slow speeds rotations (step S155), normality is represented whether the connection signal of switch 108 conducting states has been exported detect (step S156).When this connection signal has been exported, in case the rotation of swing roller 102 is stopped, by block 106 is drawn in rotary body control module 105, swing roller 102 becomes released state (step S157), make swing roller 102 rotations (step S158) with ormal weight, then, block 106 is outstanding by stages, and block 106 engages (step S159) with holding section 103.
Adopt the action variation of above explanation, only need utilize the reset force of helical spring 107, can prevent the noise (conflict sound) of generation when stop block 106 engages with holding section 103, swing roller 102 constraints can be stopped on this basis.
