Description
Technical field
The present invention relates to a kind of music facility, in particular, the present invention relates to a kind of leaf turner that is used for music easel.
Background technology
Music easel structure commonly used, usually by the spectrum plate of placing music score and the tripod that is used to support the spectrum plate form.Because often needing both hands to cooperate when playing, play by most of musical instruments, so, when using the music easel of aforementioned simple structure, just make the player have to when playing, free hand to be the music score page turning, this has not only caused great inconvenience to the player, and also can influence normally carrying out of performance sometimes.
For addressing the above problem, people begin to conceive and have designed various music easels that can automatic page turning, and from the principle of its page turning structure, existing solution is broadly divided into fixed mount rotation and roll type two classes.
Fig. 1 shows the structure of fixed mount rotation music easel, when playing, the order paging in advance of required music score to be fixed on one by one on the loose-leaf 38, the two ends at each 38 1 edge of loose-leaf are separately fixed between the last disk 39 and lower disc 37 that is installed on axostylus axostyle 36 two ends, the lower end of axostylus axostyle 36 is fixed with gear 35, and the driving-chain that gear 35 constitutes by gear 34,33,32 connects the turning cylinder 31 of motor.When the page turning of needs music score, send control signal to motor, make the turning cylinder 31 of motor turn over certain angle, turn to desired location thereby drive the loose-leaf 38 that is fixed with the performance music score, realize the purpose of music score page turning.This structure has certain reasonability, but owing to need before performance music score be fixed on the loose-leaf one by one, so it is fashionable to meet frequent replacing playing music destination field, uses very inconvenient; Because the size and the weight of loose-leaf itself under the situation of holding identical music score number of pages, adopt the inevitable volume of music easel, the weight of this kind scheme all very big, influence its practicality again; In addition, based on the restriction of structure, the movement range of loose-leaf 38 is bigger during page turning, is not suitable for comparatively crowded stage performance condition.
Fig. 2 shows the structure of roll type music easel, by Fig. 2 (A) as seen, in spectrum plate 40 both sides a reel 41 is set respectively, on two winding drum 41, twine conveyer belt 42, music score 43 is fixed on the conveyer belt 42 successively according to the performance order, when the page turning of needs music score, send control signal to the motor (not shown), make motor turn over certain angle, and rotate by the reel 41 that the gear 45,44 that constitutes driving-chain with its turning cylinder drives spectrum plates 40 1 sides, make conveyer belt 42 move the distance of a music score width, realize the purpose of music score page turning.The music score of having played then is wrapped on the reel 41 of spectrum plate 40 1 sides with the conveyer belt 42 that moves.This structure also has certain reasonability, but also has defective.Such as, in order to hold more music score, conveyer belt 42 must be longer as far as possible, and because conveyer belt 42 self all has certain thickness with music score 43, external profile diameter meeting differing greatly like that shown in Fig. 2 (B) and Fig. 2 (C) when external profile diameter when the reel 41 of spectrum plate 40 1 sides is rolled conveyer belt 42 fully and reel 41 discharge conveyer belt 42 fully, when motor is worked with constant rotational speed, certainly will cause the difference of page-turning speed in the playing procedure, promptly page-turning speed is slow excessively when playing beginning, and page-turning speed is too fast when performance will finish.The another one weak point is identical with aforesaid fixed mount rotation music easel, also be before performance, to need to be fixed on the conveyer belt music score is many pieces of, if meet frequent replacing playing music purpose occasion, use very inconvenient, and, also, make music score easily because music score of playing and the music score that will play are to be on the reel that tubular is wound on both sides, especially the music score that is fixed on the conveyer belt two ends is owing to crooked excessive the distortion, thereby accelerated oldization and the damage process of music score.

Comprehensive aforesaid each accompanying drawing as can be known, page-turning apparatus for music book of the present invention is to constitute like this: be provided with tubular sliding chute 7 in frame 16 near the place, two ends, described frame 16 is by sliding and be fixed on the little axle connection pressing plate 1 on the pressing plate 1 in tubular sliding chute 7, be provided with spring 10 between described frame 16 and the pressing plate 1, the two ends of described pressing plate 1 are provided with catch guide rail 14, the catch 12 that can slide thereon is housed on the described catch guide rail 14, one side of described pressing plate 1 is provided with flaps 2, the side that described frame 16 is parallel to described pressing plate 1 plane is provided with second power transmission shaft 17 of first power transmission shaft 8 and installation in parallel, one end of described first power transmission shaft 8 is provided with driving member 9, described first power transmission shaft 8 be provided with and described pressing plate 1 between constitute the friction roller 3 of certain pressure, one side of the described friction roller 3 described flaps 2 of being separated by is provided with the delivery wheel 4 that is installed on second power transmission shaft 17, one end of described second power transmission shaft 17 is provided with driving member 18, and the outer rim of described delivery wheel 4 is provided with paper-weight.Music score for the ease of collection is separated can also be provided with the music score reservoir vessel at the end of music score motion.
Pressing plate 1 in the present embodiment can be by doing translational motion with its fixing little axle with being engaged on the frame 16 of described tubular sliding chute 7, described catch 12 can move along described catch guide rail 14, with the placement location of standard music score and prevent the inclination that music score may occur in motion process, the surface of described flaps 2 contact music score is angle θ with the music score plane that is placed on the described pressing plate 1.Generally, 90 °≤θ≤180 °.In theory, when θ=90 °, the reliability of individual separation of music score is best, but described friction roller 3 need provide very big frictional force that the top layer music score is moved; And when θ=180 °, though described friction roller 3 does not need too big frictional force just can music score be moved, many situations that music score is moved simultaneously appear easily.Therefore, take all factors into consideration above two kinds of situations, and through repeatedly experiment, being provided with in the state of present embodiment, angle θ value can obtain comparatively desirable effect in 110 °, both can make the reliability of individual separation of music score best, the situation that friction roller 3 is stuck or dallies can not occur again.Certainly, θ=110 ° are to obtain under specific situation, and at concrete conditions such as the different materials of part and different sizes, the value of θ also can be different, and usually, the θ value is when 110 ° of left and right sides, and effect is just all well and good.
The driving force of described friction roller 3 and delivery wheel 4 is to obtain like this: owing to be provided with the certain pressure that the spring 10 by installation between described pressing plate 1 and the described frame 16 provides between described friction roller 3 and the music score that is placed on the described pressing plate 1, again since friction roller 3 and delivery wheel 4 be separately fixed on first power transmission shaft 8 and second power transmission shaft 17, and an end of first power transmission shaft 8 and second power transmission shaft 17 is separately installed with driving member 9 and driving member 18 again, so, described driving member 9 and described driving member 18 have constituted driving-chain through transmission mechanism (not shown) and drive motor (not shown), driving force can be sent to friction roller 3 and delivery wheel 4 respectively.
The course of work of embodiment 1 is: music score 24 is put between described pressing plate 1 and the friction roller 3 by the performance order is stacked, and the catch 12 on the moving guide rail 14 makes it to keep off the both sides at music score 24, to guarantee that music score 24 deflection can not occur in the page turning process.When control circuit received the page turning signal, drive motor sent rotatory force to power transmission shaft 8 by transmission mechanism, drove described friction roller 3 and rotated.Because friction roller 3 and be between the music score 24 on the pressing plate 1 and have certain pressure, so, the friction roller 3 that is rotating can produce the frictional force of impelling its motion to music score 24, meanwhile, music score with movement tendency is subjected to the resistance that flaps 2 provides, the top layer music score that contacts with friction roller 3 continues plane motion along described flaps 2 because of the frictional force effect of described friction roller 3, and all the other music score then rest on original position.When the top layer music score that continues motion touches delivery wheel 4 or paper-weight, to adjust the direction of motion, and under the carrying capacity effect that described delivery wheel and paper-weight provide orbiting motion according to the rules, until entering the music score reservoir vessel that music score motion final position place is provided with.
Embodiment 2:
Fig. 9 (T), Fig. 9 (R), Fig. 9 (F) show another kind of technical scheme of the present invention with the form of stereogram, side view and front view respectively.Wherein, Figure 10 shows the rack construction of present embodiment; Figure 11 (T), Figure 11 (R), Figure 11 (F) show the later structure of baffle plate that present embodiment is removed guide plate 5a and frame one side; Figure 12 shows paper-weight and delivery wheel 4, flaps 2, the position relation of friction roller 3 and the placement situation of being made up of guide plate 5a, pressure roller 5b of music score 24 respectively with the form of front view and side view.
Comprehensive above accompanying drawing is as seen: the page-turning apparatus for music book of present embodiment, some is different for the mounting means of each parts and embodiment 1.In the present embodiment, described pressing plate 1 is that the little axle 6 by described frame 16 both sides is connected with frame, also be provided with spring 10 between described frame 16 and the pressing plate 1, described pressing plate 1 plane is provided with catch chute 13 near the position at two ends, the catch 12 that can slide therein is housed in the described catch chute 13, one side of described pressing plate 1 is provided with flaps 2, the contacted side of described pressing plate 1 and music score surface is arranged with second power transmission shaft 17 of first power transmission shaft 8 and installation in parallel in parallel, described first power transmission shaft 8 is provided with the friction roller 3 that forms certain pressure with described pressing plate 1, one side of the described friction roller 3 described flaps 2 of being separated by is provided with and is installed on delivery wheel 4 on second power transmission shaft 17, and the outer rim of described delivery wheel 4 is provided with paper-weight.The music score that is separated for the ease of collection can also be provided with the music score reservoir vessel at the end of music score motion equally.
Though the paper-weight in the present embodiment is different with shape among the embodiment 1, and is basic identical with the set-up mode of paper-weight among the embodiment 1.
In this embodiment, described pressing plate 1 can be shown in Figure 11 (R) like that, rotate at center around little axle 6, described catch 12 can be in catch chute 13 slip locations, come standard to be placed on music score on the described pressing plate 1, and prevent its contingent inclination in motion process, the surface of described flaps 2 contact music score is angle θ with the music score plane that is placed on the described pressing plate 1, identical with embodiment one, under normal conditions, the span of θ is 90 °≤θ≤180 °.Take all factors into consideration its application characteristic,, can obtain ideal effect when getting near 110 ° value, at this moment, both can make the reliability of individual separation of music score best, can not occur friction roller 3 again and be stuck or dally situation with angle θ being provided with in the state of present embodiment.Certainly, θ=110 ° are to obtain under specific situation, and at concrete conditions such as the different materials of part and different sizes, the value of θ also can be different.
The driving force of friction roller 3 described in the present embodiment and delivery wheel 4 obtains in mode similarly to Example 1: described friction roller 3 and be placed between the music score on the described pressing plate 1 and be provided with certain pressure, this pressure is provided by the torsionspring that is installed in spring 10 between described frame 16 and the pressing plate 1 or is arranged at little axle 6 places.Because friction roller 3 and delivery wheel 4 are separately fixed on first power transmission shaft 8 and second power transmission shaft 17, and first power transmission shaft 8 links to each other with the drive motor (not shown) through the transmission mechanism (not shown) with second power transmission shaft 17 and constitutes driving-chain, driving force can be sent to friction roller 3 and delivery wheel 4 respectively.
The course of work of embodiment 2 is: music score 24 is put between described pressing plate 1 and the friction roller 3 by the performance order is stacked, adjust the catch 12 in the described catch chute 13, make it to keep off both sides, to guarantee that music score 24 deflection can not occur in the page turning process at music score 24.When control circuit received the page turning signal, drive motor sent rotatory force to first power transmission shaft 8 by transmission mechanism, rotated thereby drive friction roller 3.Because friction roller 3 and be between the music score on the pressing plate 1 and have certain pressure, so, the friction roller 3 that is rotating can produce the frictional force of impelling its motion to music score 24, meanwhile, music score with movement tendency is subjected to the resistance that flaps 2 provides, so have only the top layer music score that contacts with friction roller 3 can continue motion, all the other music score then rest on original position.When the top layer music score that continues motion touches delivery wheel 4 and paper-weight, will adjust the direction of motion, and under the carrying capacity effect that described delivery wheel 4 and paper-weight provide orbiting motion according to the rules.
The above setting of the present invention, can remedy the deficiencies in the prior art, but in order to make its better effects if, and consider, though reducing along with angle θ value from the angle of promoting its applicability, individual separation property of music score can improve thereupon,, the flexural deformation that produces when music score is separated also can be difficult thereupon, and that is petty, if the music score that uses is thicker, just might cause the situation of friction roller 3 idle running or jam; On the contrary, along with the increase of angle θ value, though can avoid the problems referred to above, individual separation property of music score may descend again thereupon, perhaps the situation that many music score move simultaneously can occur.In order to overcome this possibility defective, make described flaps 2 among the present invention and can also be arranged to following dual mode: the one, as Figure 13 (R1), Figure 13 (R2) illustrated, flaps 2 adopted plastic board, paper, rubber, timber, metal sheet and other material that easily produces distortion in working order down to make; The 2nd, as Figure 14 (R1), Figure 14 (R2) illustrate, flaps 2 is installed on the hinge member that is fixed in frame 16, and be connected and fixed on the spring support of frame 16 by spring 26, it can be rotated by the little axle 25 around described hinge member center under the constraint of spring 26.Such set-up mode can make angle θ increase with the increase of active force between music score and the described flaps 2, and its effect is:
When using thin music score (shown in Figure 13 (R1) and 14 (R1)), music score 24 produces movement tendency under the frictional force effect that described friction roller 3 provides, and to the certain pressure of described flaps 2 generations, at this moment, described flaps 2 will begin to produce distortion under this pressure effect, until the corner α that produces as shown in the figure, 2 pairs of top layer music score of described flaps provide resistance F (α), make music score under the effect of resistance F (α), its front end produces flexural deformation, and moves and separate with other music score along described flaps 2;
When using thicker music score (shown in Figure 13 (R2) and 14 (R2)), music score 24 produces movement tendency under the frictional force effect that described friction roller 3 provides, and to the certain pressure of described flaps 2 generations, at this moment, described flaps 2 will begin to rotate under this pressure effect, until the corner σ that produces as shown in the figure, 2 pairs of top layer music score of described flaps provide resistance F (σ), make music score under the effect of resistance F (σ), its front end produces flexural deformation, and moves and separate with other music score along described flaps 2.
In above-mentioned set-up mode, because thin music score just can produce flexural deformation under less drag effect, and thicker music score will just can produce flexural deformation under big drag effect, so, generally speaking, the pass of both corners is α＜σ.Analyzing thicker music score can move and finish paging along flaps, is because described flaps 2 has produced bigger corner σ, so music score reduced along the described flaps 2 required deflection that moves, and has been subjected to bigger directed force F (σ).Can reach a conclusion: two kinds of set-up modes of this of described flaps 2, relative littler value scope is obtained with angle θ between the plane of described pressing plate 1 placement music score in the surface that can make its contact music score, this scope or even 0 °＜θ＜180 °.
Paper-weight among the present invention has 2 major functions: the one, and cooperating with described delivery wheel 4 provides certain carrying capacity to music score; The 2nd, make music score according to the rules orbiting motion and music score is transported to assigned address.
In order to realize above-mentioned functions, described paper-weight can as Fig. 5, Fig. 7, Fig. 9, shown in Figure 12, constitute jointly by guide plate 5a and pressure roller 5b; Also can as Fig. 8 or shown in Figure 11, constitute separately by described guide plate 5a or pressure roller 5b.
Two kinds of paper-weights that are made of separately described guide plate 5a and pressure roller 5b respectively have its pluses and minuses:
The advantage of guide plate 5a is that music score is had good motion guide effect, but installation accuracy is had relatively high expectations, and excessive alignment error can cause delivery wheel 4 jams maybe can't provide carrying capacity to music score;
The advantage of pressure roller 5b is that the position is easy to adjust, and carrying capacity can stably be provided, but when paper-weight only is made of pressure roller 5b, should arrange that abundant pressure roller 5b comes music score is play the guiding role, and the size of pressure roller 5b is unsuitable too small, otherwise the situation of jam music score may occur.
In fact, the paper-weight among the present invention is not limited to these two kinds of forms and concrete shape, according to concrete applicable cases with and the function in whole device, brought into play, can carry out the setting of various ways and shape.
According to the different situations that is provided with, pressure roller 5b among the present invention can be installed on the guide plate 5a by little axle earlier, be fixed on (embodiment one shown in Fig. 5 (T)) on the described frame 16 in company with guide plate 5a again, also can be directly installed on (embodiment two shown in Figure 12 (R)) on the frame 16 by the little axle that is arranged on described pressure roller 5b center.
The user mode of paper-weight described in the present invention can have multiple, as show the situation that constitutes paper-weight by guide plate 5a and pressure roller 5b jointly at Fig. 5 (F), Fig. 8 (F) shows the situation that is made of paper-weight guide plate 5a separately, and Figure 11 (F) shows the situation that is made of paper-weight pressure roller 5b separately.
According to the complexity that its installation site is adjusted, the position of described paper-weight and delivery wheel 4 relation can be set to various ways: from positive view, guide plate 5a covers delivery wheel 4, guide plate 5a and delivery wheel 4 and staggers; Pressure roller 5b covers delivery wheel 4, pressure roller 5b and delivery wheel 4 and staggers.View from the side, the outline line of the outline line of guide plate 5a and delivery wheel 4 from, tangent or crossing; The outline line of the outline line of pressure roller 5b and delivery wheel 4 from, tangent or crossing.
For the paper-weight that the installation site is easy to adjust, can take the installation form of guide plate 5a covering delivery wheel 4 shown in front view 12 (F), so both can provide reliable carrying capacity, can prevent jam delivery wheel 4 again; In the side direction view shown in Figure 12 (R), guide plate 5a can contact or be separated with delivery wheel 4, the described form that contacts or be separated, this depends primarily on the smooth degree of thickness, guide plate 5a and music score 24 contact surfaces of used music score 24 and the size that drives the driving force of delivery wheel 4.Need to prove: when described guide plate 5a contacted with delivery wheel 4, the motion stabilization of music score was reliable, but correspondingly motor need provide bigger driving force and energy consumption higher; When guide plate 5a separates with delivery wheel 4, though can select lower-powered motor for use, at this moment the situation that delivery wheel 4 and music score skid may appear.So best set-up mode also needs material, size, shape and other concrete conditions according to part to select to determine.When needs guide plate 5a reliably contacts with delivery wheel 4, can on guide plate 5a, add spring and guarantee suitable contact force between the two.
Adjust the paper-weight of difficulty for the position, the position relation of described paper-weight and delivery wheel 4 can adopt the installation form that staggers as guide plate 5a in the front view 8 (F) and delivery wheel 4.The advantage of Bu Zhiing is like this: when assembly precision was not enough between low or part when the dimensional accuracy of part self, a spot of error can not cause the outer surface of delivery wheel 4 to be close to paper-weight and situation about can't rotate.Yet, if the distance that staggers is excessive, can cause the insufficient pressure that contacts of delivery wheel 4 and music score, thereby form the situation that delivery wheel 4 dallies easily.So, be provided with under the situation that guide plate 5a and delivery wheel 4 stagger, can take the guide plate 5a that illustrates respectively as lateral view 8 (R1), Fig. 8 (R2), Fig. 8 (R3) and music score contact a side outline line and as described in the outline line of delivery wheel 4 from, tangent or crossing form.
With in like manner aforementioned, described pressure roller 5b covers the form of delivery wheel 4 shown in front view 7 (F), 12 (F), in the lateral plan shown in Fig. 7 (R), Figure 12 (R), described pressure roller 5b can contact or be separated with delivery wheel 4, the situation that both contact or are separated depends primarily on the smooth degree of thickness, pressure roller 5b and music score contact surface of used music score and the size that drives the driving force of delivery wheel 4.Need to prove: when described pressure roller 5b contacted with delivery wheel 4, the motion stabilization of music score was reliable, but correspondingly motor need provide bigger driving force and energy consumption higher; When pressure roller 5b separates with delivery wheel 4, though can select lower-powered motor for use, at this moment the situation that delivery wheel 4 and music score skid may appear.So best set-up mode also needs material, size, shape and other concrete conditions according to part to select to determine.When needs pressure roller 5b reliably contacted with delivery wheel 4, the spring 11 that can add as shown in Figure 12 (R) guaranteed suitable contact force between the two.
1. cam-shaped: for example shown in Figure 15.In this is provided with, one side of described friction roller 3 is provided with gear wheel 17, or both sides are provided with gear wheel 17 respectively, greater than the radius of sunk part 3b, the effect of She Zhiing is music score can only be contacted with the projection 3a of described friction roller 3 and can't to contact sunk part 3b to the radius of described gear wheel 17 like this less than the radius of the projection 3a of described friction roller 3.Described gear wheel 17 be manufactured into can not situation with respect to described friction roller 3 independent rotation under, its surface that contacts with music score 24 should have lower coefficient of friction; When described gear wheel 17 is manufactured into can be with respect to described friction roller 3 independent rotation the time, its surface that contacts with music score 24 can have high friction coefficient.
2. wait circle splicing shape: for example shown in Figure 16.In this is provided with, the surface of described friction roller 3 can be spliced by two or more material, why be provided with like this, be to differ bigger character for the coefficient of friction that utilizes two kinds of materials and music score 24 surfaces, music score is in the high frictional property material 3c zone of described friction roller 3 is moved, and make music score be in stop motion in the low friction material 3d zone of described friction roller 3.The friction roller 3 of this set not only has the function of use identical with section cam-like friction roller 3, and advantage is to eliminate section cam-like friction roller 3 shown in Figure 15 front and back vibration because of the music score that variation caused 24 of its radius.
3. peripheral zigzag: for example shown in Figure 17.The friction roller 3 of this shape is when contacting with music score 24, because the strain of its cross-sectional edge can provide bigger frictional force to music score 24, thereby prevents that friction roller 3 from skidding.
Described delivery wheel 4 among the present invention, also friction roller 3 as described is the same, both can take the combining form of skin-material parcel inner hub, also can be made by the frictional property material monolithic.Just owing to the difference of both required frictional force, some distinguishes the frictional property height of selected material.
Driving member 9 and 18 among the present invention according to actual state, can be set to belt wheel, gear, worm gear or shaft joint etc.
Page-turning apparatus for music book of the present invention compared with prior art, its major advantage is:
(1) only needs music score is placed on the music stand by the performance order before playing stackedly, and need not many fix respectively, so strengthened practicality;
