Embodiment

Referring to each accompanying drawing, before the structure to the whole invention that goes out illustrated in Figure 1 is described, be familiar with earlier each accompanying drawing structure of Fig. 2, Fig. 3, Figure 11.

Among Fig. 2, be illustrated as the structure of " monolithic is deposited platform ", it is 1 the overlapping concrete structure of depositing the wherein a slice in the platform of being labeled as among Fig. 1.Among Fig. 2, mark 21 is one " putting the dish position " of placing video disc, and three concentric circless shown in 21 districts are the projection on three different planes of terrace.Wherein cylindrical is outward for depositing the stylobate plane, and the cylindrical and the second road circle are one section falling ramp, and a circle circular planes at second road circle and circle place, the 3rd road is called " putting the dish step ", and the 3rd road circle inner plane hangs down than circular planes again.Wherein, 121 millimeters of the outer circle diameters (referring to middle circle) of " putting the dish step ", 2 millimeters of ring widthes.When video disc places " putting the dish position " just with this circle loop contacts, the surface of contact on the video disc is roughly on the circle of ragged edge 1 mm wide, and is injury-free because of floating sky with regard to the interblock that has guaranteed the video disc inner edge like this.An external breach of 21 districts is called " getting the dish passageway " again, and it is that monolithic is deposited the openwork part on the platform.Act as and " to put the dish position " by the trailing arm that promotes video disc mechanism from this indentation, there and take or insert video disc away.Four of during Fig. 2 shows other and 21 districts with shape for other four " putting the dish position ", together with 21 interior, every monolithic is deposited platform can deposit five video discs.Among Fig. 2,22 districts are depicted as a vacancy circular hole again, and it is called " crossing the dish hole ", and it is that a round footpath is 125 millimeters a circular hole, act as the last lower channel when supplying the taking-up of quilt work dish to insert.Also there is a breach its outside, and effect is with the breach of " putting the dish position ".Also be a hollow out shown in 23 districts among the figure, this is the hollow out of a gear-like.To insert one " central cylinder " in the middle of the gear of this hollow out circle, the circle that numerous gear pleodont points surrounds is feasible to be deposited platform and can closely combine with cylinder outer wall and do not have loosening.24 indications are gear circle entity among the figure again, and 24 indications are a pleodont point specifically.26 indications are a special empty tooth among the figure again, its " base position gear lacks " by name.It is darker than other empty teeth.The outside of the open seam 31 during it shows corresponding to Fig. 3 when monolithic is deposited platform and is placed on the central cylinder, parts in the cylinder will insert " base position gear lacks " that all monolithics are deposited platform by the open seam 31 of Fig. 3 with the pin of a vertical setting of types, be positioned at same reference position thereby all monolithics are deposited platform.25 indications are a circle convex tendon among Fig. 2 again.It is each outstanding part of positive and negative two surfaces of depositing platform at monolithic, deposits the contact portion of platform when overlapping as two.27 indications are the up/down perforation hole of six five equilibriums on the convex tendon among the figure, " deciding dish position unthreaded hole " by name, they are corresponding one by one with five " putting the dish position " and one " crossing the dish hole ", act as selected when depositing platform and rotating, detect be positioned at that all deposit platform certain some variable quantity of the photoelectricity testing part at these unthreaded hole two ends select that this deposits platform certain " put the dish position ".But deposit the concrete mechanical realization referenced patent file of platform: ZL00267059.3 about this.

Among Fig. 3, be illustrated as the structural representation of central cylinder.It is labeled as 2 structural drawing for Fig. 1 in showing.In the diagram, 31 indications are a narrower open slot on the cylinder, " base position pin passes seam " by name, and its A/F is about 5 millimeter.Saying before its effect, is to insert pass through directly of " base position gear lacks " that outer all of cylinder are deposited platform for the pin sheet in the cylinder.Among the figure, 32 indications are the open slot of a broad on the cylinder again, " the roll film gear passes seam " by name.Its A/F is roughly about 2 centimetres.Its effect is to stitch by the extrapolated and engaging-in gear of depositing the platform group of this seam for the winding mechanism in the central cylinder.The rotation of the roll film gear on the winding mechanism will drive unique a slice " monolithic is deposited platform " rotation and then select certain and " put the dish position ".The round external diameter of this central authorities' cylinder about 9 centimetres, highly is about 25 centimetres roughly.

Among Figure 11, divide Figure 111 to be illustrated as the unitary construction that promotes video disc mechanism.Introduce each minute graph structure earlier, its principle of work is described then.Dividing Figure 112 is the clamping plate of two symmetries; Dividing Figure 113 is the vertical view signal of two clamping plate.Two guide rails (reference: can consider cancellation when specifically implementing) are also arranged respectively on two clamping plate.The effect of these clamping plate shows as dividing Figure 111, and it is to be used for making the link arm of video disc saddle can not left-right rotation and can only slide up and down in the scope between two cradle-splints.Dividing Figure 114 is a fixedly signal of stomidium, and dividing Figure 115 is one threaded " swingle ", and dividing Figure 116 is a small machine, its " lifting motor " by name.Promote motor and be connected with swingle, swingle rotates under the restriction of fixing stomidium when the lifting motor rotation.Dividing Figure 117 again is the signal that is connected of saddle and its link arm, and dividing Figure 118 is the structure signal of link arm, divides Figure 119 to overlook signal for link arm, and component 1110 is the signal of dish saddle structure.Wherein, the right-hand member of link arm be a tapped turncap, it is spun on the swingle in mechanism.Like this, when promoting driven by motor swingle forward or reverse, because the restriction of two straps, the net result of motor rotation is exactly that link arm moves up and down on a perpendicular line.In the CD server complete machine, " crossing the dish hole " center that the center of this link arm saddle and overlapping monolithic are deposited platform coincides.The principle of work of its interlock will be spoken of in Fig. 1 explanation.In addition, when complete machine was worked, link arm was usually located at lowest order.

Refer now to member shown in Figure 1.Among the figure, 1 indication is overlapping " monolithic is deposited platform ", based on illustrated clear display, has only part to deposit the platform combination among the figure.In actual complete machine, deposit platform with 40 monolithics and be combined as suitable.Like this, complete machine is deposited CD quantity and then is 200.Preamble said that because the effect of " base position gear lacks ", all platforms of depositing all were in a benchmark position.More careful explanation to " benchmark position " notion is: overlappingly deposit overlooking still of platform and show as Fig. 2.Promptly " cross dish hole ", " decide dish position unthreaded hole ", " putting the dish position ", " base position gear lacks " corresponding up and down, coincidence fully.During Fig. 1 showed, " crossing the dish hole " was positioned at the left end of depositing the platform group, and the link arm of the lifting video disc mechanism of 3 indications and dish saddle will operations up and down in these " cross the dish hole ".The link arm of the lifting video disc mechanism of 3 indications is usually located at lowest order, and diagram is only clear for signal.See that again 2,2 indications among Fig. 1 are " central cylinder ", its main effect also is that each " monolithic is deposited platform " can be on the same center of circle.Also have two illustrated open slots on central authorities' cylinder, the left side is narrower is " base position pin passes seam ", the right broad be " the roll film gear passes seam ".4 indications are the clamping rings of " shading ring " by name among the figure again.It is actual to be to be installed on the centre of depositing the platform group, and it is fastened on the cylinder outer wall, deposits the platform layering with 40.Its effect is the weight power of decomposing " monolithic is deposited platform " that be positioned at lower floor, and then reduces the operating load that " roll film gear " goes up " roll film motor "." shading ring " load capacity with " roll film motor " in actual design is provided with its use number, and allows for zero.As consider that use " decides dish position unthreaded hole ", the manufacturing external loop diameter of this shading ring should be same as the convex tendon external loop diameter on " monolithic is deposited platform ".And six identical " deciding dish position unthreaded hole " should be arranged also.

The simple principle of work of this composition member is described now.To get a video disc from " dish storehouse " is example, initial conditions before the work are: the latch of " fixed layer is decided the disc player structure " stretches into " base position gear lacks " of depositing the platform group by " base position pin passes seam " in the central cylinder, makes all " monolithic is deposited platform " be in same reference position.Another service part " roll film gear " of " fixed layer is decided the disc player structure " is not also deposited the normal gear seam of platform group by " the roll film gear passes seam " engaging-in part.The link arm of " promote video disc mechanism " (and dish saddle) is in lowest order, and is lower than and descends a slice to deposit platform most.After starting working, by " the fixed layer motor " running of " fixed layer is decided the disc player structure " in the central cylinder, its operation result is that " removable pin " (seeing hereinafter explanation for details) and " roll film dolly " are up to the center of chosen " monolithic is deposited platform " by lowest order earlier.Be that " roll film dolly " is extrapolated to cylinder then, " roll film gear " accurately engagement goes up this selected " monolithic is deposited platform " gear seam." roll film gear " band engaging-in selected 4 of Ge Yue up and down that deposit platform of part pin sheet (about 5 centimetres of height) together deposit platform gear seam simultaneously.Be that unique " removable pin " in " base position pin " withdraws from " base position gear lacks " that part is deposited the platform group backward afterwards, its discharges with the chosen platform of depositing is that about up and down 5 of center deposit platform.So, till current, chosen in " roll film gear " engagement deposited platform can rotate under the drive of " roll film gear ", and other are deposited platform and still are fixed on the reference position by the partial fixing pin sheet on " base position pin " and " the roll film gear ".Next step is " roll film motor " running again, drives the chosen platform of depositing by " roll film gear " and rotates, and the result turns to other when depositing in " crossing the dish hole " that platform forms when chosen chosen " putting the dish position " of depositing on the platform, and " roll film motor " is out of service.To this moment, just there is a unique video disc to be positioned at diagram and deposits the hollow cylinder that platform group left end " crossing the dish hole " form (promptly " dish hole ").Next step is exactly " lifting motor " running, and the link arm band is up by lowest order with the dish saddle.The last circular cone wedge angle of dish saddle is over against the center hole of selected video disc.Link arm continues up, and video disc is gently inserted on the dish saddle.Finally be that the dish saddle is up to most significant end, and deposit platform plane (taking this video disc away) for other mechanisms above going up most a slice.Just finished to this and once to have got the dish process.

Reference above working procedure, no longer explanation herein when " dish storehouse " internal memory dish.Below describe in detail by the member of diagram to " fixed layer is decided the disc player structure " in the central cylinder.

Fig. 4 is " the fixed layer is taken turns " structural representation in the central cylinder interior " fixed layer is decided the disc player structure ".Earlier the diagram monomer is described: 41 indications are illustrated as overlapping " monolithic deposit platform " for " fixed pin " (it and removable pin are referred to as " base position pin " mentioned above), 45 indications for " fixed layer motor engaged wheel ", 46 for " crawler belt tape base ", 44 indications for " removable pin ", 43 indications for " fixed layer motor ", 42 indications; Place, the activity cutting bottom face that the most advanced and sophisticated place face of some a stylus pin sheet, some b refer to " removable pin ".See again among the component I that the left side normal pin face at some a place is the work pin face in the insertion " base position gear lacks ".42 indications are " removable pin " unique in the mechanism in the component, and it will operation up and down in certain space, left side under the running of " fixed layer motor ".Its pairing several " monolithic is deposited platform " will can not be in free rotary state because of having the pin sheet in " base position gear lacks " when its cutting is inwardly withdrawed from.44 indications is " fixed pin " in the component, why is designed to form a normal pin face by numerous " fixed pins ", is decided by its actual structural principle.See again among Fig. 4 that the situation when not withdrawing from is transplanted a cutting in the activity that component I, II, III are illustrated as " removable pin ", component IV, V, VI signal be the cutting of " removable pin " situation when withdrawing from (base position gear lacks).Component VII is " removable pin " textural association signal on " crawler belt tape base ".In actual design, the cutting of being somebody's turn to do " removable pin " can be moved by electromagnet.See component VIII again, what this component was illustrated is the corresponding situation with chosen " monolithic is deposited platform " in " a fixed layer motor " operation back " removable pin ".In the component, the dash area on the left side is " removable pin ", and the dash area on the right is chosen " monolithic is deposited platform ".In practice, some a place pin face should stretch in " base position gear lacks " of depositing the platform group, promptly in the component about two parts superposed part should be arranged, the diagram technique of painting is a clear display.With diagram, when " removable pin " on the left side when withdrawing from backward, the right comprises that selected " monolithic is deposited platform " about 5 are deposited platform and all can the right of freely rotating be arranged because of " base position gear lacks " obtains discharging.Next be exactly how to make these 5 to deposit in the platform other 4 and deposit that platform is fixed once more and how the chosen platform of depositing rotates.See hereinafter " roll film dolly " system construction signal for details.

Among Fig. 5, illustrated is the structure of " removable pin " and " fixed pin ".Dividing Figure 51 is the understructure of " removable pin "; Dividing Figure 52 is base vertical view; Dividing Figure 53 is the activity cutting structure signal of " removable pin "; Dividing Figure 54 is the one-piece construction signal of " removable pin "; Dividing Figure 55 is the structural representation of " fixed pin ".On the crawler belt tape base of " fixed layer wheel ", numerous " fixed pins " thus accurately paste " fixed pin " that has been combined into a section longer by slices.

Fig. 6 projection signal in central cylinder for fixed layer wheel and pin sheet.In the diagram, 2 indications are central cylinder; 32 refer to " the roll film gear passes seam " on the cylinder; 31 refer to " base position pin passes seam " on the cylinder; 5 indications are the projection of " fixed layer wheel " and pin, and its mid point a indication is same as Fig. 4 mid point a, promptly insert the pin face in " base position gear lacks " of owning " monolithic is deposited platform ".

Fig. 7 is the signal of roll film vehicle structure.Dividing Figure 71 is the one-piece construction constitutional diagram; Dividing Figure 72 is " fixed pin " structural representation of roll film system; 73 indications are " roll film gear "; 74 indications are " roll film motor "; 75 is roll film dolly base; 76 indications are the base moving wheel, and it may be defined as " stepper motor ".Its operative scenario is described: " stepper motor " operation, the roll film dolly is advanced to the right, it will engage into the normal gear seam of part " monolithic is deposited platform " through " the roll film gear passes seam " in complete machine.During engagement, the roll film gear is aimed at unique a slice " monolithic is deposited platform ", and its " fixed pin " pins this and choose and deposit about 4 of up and down each of platform and deposit platform gear seam.Withdraw from as front said " removable pin " then in " base position gear lack ", discharge that to deposit platform be that about 5 of center deposit platform to choose.Next be exactly " roll film motor " operation, drive this unique platform of depositing by " roll film gear " and carry out rotation work.Thereafter " deciding the dish position " work stoppage in transit of controlling the roll film motor by depositing " decide dish position unthreaded hole " the cooperation photoelectric detector on the platform transfers and reaches again.

Fig. 8 is the simple and clear signal of fixed layer principle.Each split of explanation earlier.44 indications are " fixed pin " on " fixed layer wheel "; 42 indications are " removable pin "; 46 indications are overlapping " monolithic is deposited platform "; 72 indications are " fixed pin " on the roll film dolly; 73 indications are " roll film gear ".In its whole structure, " removable pin " of 42 indications carries out contour motion with " the roll film gear " of 73 indications in central cylinder.Promptly the central point of " roll film gear " and " removable pin " is all the time at sustained height.Before fixed layer work was carried out, " roll film gear " moved back in central cylinder.Fixed layer motor rotation, " removable pin " on it and " fixed pin " slided up and down in " base position gear lacks " of " monolithic is deposited platform " group.After fixed layer motor stopped, the central point of " removable pin " was aimed at the chosen platform of depositing; The roll film dolly steps to outside " the roll film gear passes seam " afterwards, " roll film gear " and " fixed pin " on it engaging-in as shown to deposit platform be that several of center deposit in the gear seam of platform to choose, be that " removable pin " 42 withdraws from " base position gear lack " left then, discharge several that it fixes and deposit platform.On illustrated the right because " roll film gear " and on " fixed pin " engaging-in be that several of center deposit in the platform gear with the selected platform of depositing, be equivalent to once more these to be deposited platform and be fixed on the benchmark position.At this moment, have only by " roll film gear " engagement selected deposit platform can flat turn moving outside, other are deposited platform and all are unable to stir any more in the reference position because of the effect that is subjected to pin.That's about the size of it for fixed layer principle.Figure is shown with a problem, and promptly " base position pin " profit " roll film gear " about diagram is divided into, only is that contrast is clear originally all in the same side of depositing platform group annular wheel (detailed ginseng Figure 10), indicates hereby.

Summary " deciding dish " mechanism.In technical solution of the present invention, decide that dish position work realizes by the design of " deciding dish position unthreaded hole " on " monolithic is deposited platform ".The front said, deposit the platform group entirely when the reference position all " deciding dish position unthreaded hole " be corresponding one by one from top to bottom.Like this, we can deposit platform and descend a slice to deposit the platform two ends most an optical transmission/reception device is set in a slice that goes up most of some unthreaded holes.Light path is unobstructed when initial, and when roll film gear mesh a slice was deposited platform and carried out rotation work, the light path of detection is break-make clocklike.This is owing to be rotated other that deposit platform and " decide dish position unthreaded hole " and entered this unthreaded hole position to cause." decide dish position unthreaded hole " and make this when other and survey light path when unobstructed, illustrate that " putting the dish position " of this unthreaded hole correspondence forwarded public " crossing the dish hole " position, the high order end of depositing the platform group during promptly Fig. 1 shows to.We just can carry out the selection of " putting the dish position " by the counting to this light path break-make situation like this.That is reached the purpose of " deciding dish ".

Besides bright Fig. 9, Fig. 9 be the roll film gear with removable pin be connected the structure situation, both interconnect the contour operation that has guaranteed them.In the diagram, dividing Figure 91 is their connection signal; Dividing Figure 92 is the structure signal of removable pin on the crawler belt tape base of fixed layer driven by motor; Dividing Figure 93 is the component composition signal of cylinder and " slip ring " by name of " slide bar " by name; Divide Figure 94 to be " slip ring " signal; Dividing Figure 95 is " slip ring " connection signal on the crawler belt tape base; Divide Figure 96 to be the signal of roll film dolly.The member situation is done an explanation: slide bar is an elongate cylinder that appearance smooth finish is very high, and its position is fixed.Slip ring is one can closely be linked in annulus and two braces on it that slide up and down on the slide bar, and the first is connected with the crawler belt tape base in two braces, and this slip ring just can carry out (contour up and down) motion synchronously with removable pin like this; Brace two is horizontal platform structures, puts on it with the roll film dolly.The roll film dolly can carry out stepping and retreat two kinds of actions on platform, the roll film gear can mesh or withdraw from the gear seam of depositing the platform group during action.Refer now in the diagram principle of work of dividing the structure shown in Figure 91: make the roll film gear can be all the time and the centrally aligned of removable pin because of slip ring is connected with the crawler belt tape base, slide bar supports the transition force of synchronousing working of force and roll film gear and removable pin as roll film dolly master.The running of fixed layer motor makes crawler belt operation (the operation highs and lows of available two electric spacing restraint pins) up and down in certain vertical section height at position, removable pin place.Like this, because crawler belt position, removable pin place has only vertical movement, just realized making roll film gear and removable pin carry out the possibility of contour motion by the transition of slide bar slip ring.

Below be illustrated more clearly in roll film cart system and the situation that combines of deciding layer electric system.Show as Figure 10, divide Figure 101 whole " fixed layer is decided dish " system that is in central cylinder, to overlook signal; Dividing Figure 102 still is roll film dolly and the segment section face signal of fixed layer with crawler belt.Divide among Figure 101, the member of introducing in Fig. 6, the part that increases in the component is parts such as roll film dolly and slide bar slip ring.In the component, some c indication is a slide bar, and some d indication is a slip ring, and some e indication is the roll film dolly that is positioned on the slip ring platform.Again among the figure, part shown in the dotted line be the slip ring annulus a part with its on the signal of the brace that is connected with crawler belt.Low order end small arrow to the right promptly is illustrated as the step direction of roll film dolly in the component.Supplementary notes is once more, in the outside of central cylinder, for depositing the annular wheel circle of platform.Wherein, the pin sheet that sees through in " base position pin passes seam " just often inserts " base position gear lacks " that all deposit platform; The roll film dolly is deposited engaging-in part during by the direction as shown stepping in the ordinary gear seam of platform.

More than be the complete machine basic building block of whole utility model.Certainly, in order to reach the complete machine practicality, also need introduce other necessary members.For example, the electronic unit and the interlock circuit of the operation of control complete machine, the outside framework structure of machine product etc.These can be quoted from current practical technique.In addition, below remark additionally, do the product design reference about the electrical principle of fixed layer (selected monolithic is deposited platform).In the utility model, what use is a kind of optical transmission/reception device to fixed layer principle (running promptly how to control " fixed layer motor " makes " removable pin " rest on an accurate height).Get two horizontal side by side very near transistors that lean on, one is a luminotron, and one is photoelectric tube.Two pipes are mutually isolated, and to equidirectional a slot light slit are arranged respectively.When this device (probe) can be owing to there being reflected light to make whole device that output (Photoelectric Detection) be arranged during near the object of a class " lean type ".Design a kind of " black and white band " again, be long vertical bar shape, the rectangular chequered with black and white horizontal stripe of portrayal of going up, black wide narrow in vain.Again this band accurately is affixed on the central cylinder inner wall, makes the corresponding a slice " monolithic is deposited platform " of the narrow leukorrhea of each bar.The probe of two light pipes that again preamble mentioned is loaded on somewhere on the platform of " slip ring ", and it is close on " black and white band ".Like this, if we receive light time device output low level with no reflection events, have reflected light output high level to be as the criterion, when " slip ring " was up by lowest order, this electrooptical device will be exported height (pulse) level of continuous variation.Connect a counting circuit again, high level is counted.This counting assembly is controlled the operation of " fixed layer motor " again.Like this, also just reached selected work by accurate location to " monolithic is deposited platform " to light belt.
