In above-mentioned article method of counting, original stock number can according to the counting of the article by described specified point during restowing and between delivery date on sale article counting by specified point determine.
In above-mentioned article method of counting, original stock number can according to the counting of the article by described specified point during restowing and between delivery date on sale article counting by specified point determine that and the described number of articles by specified point is that the count value of the article that obtain from experimental result according to depending on count value that counter provides and the corresponding relation between the estimated value are estimated during restowing.
Therefore, according to the present invention (seeing above-mentioned piezoelectric sensor and voltage sensitive sensor), when article during by the position corresponding with specified point in the passage, piezoelectric sensor or voltage sensitive sensor are exported an electric signal at every turn when receiving acting force (impulsive force or stamping press).According to this output, can count the quantity of passing through the article of specified point.In addition, if apply acting force when Individual Items are on the diagonal position or repeatedly beat by specified point and described article, only start first output of each sensor, and the every other output that occurs in the predetermined short time is under an embargo, thereby has prevented the error count that causes by beating.
In addition, according to the present invention (seeing above-mentioned counter), sound detects through sound-producing device output and by microphone according to the article passage.Add up the quantity of passing through the article of specified point according to the sounding number of times that detects.
Particularly, when article are that goods on the automatic vending machine and passage are simultaneously when depositing the shelf of goods and goods output transmission channels, according to the output of piezoelectric sensor or voltage sensitive sensor or microphone, during statistics is restowed the phase one and the goods number that passes through during selling goods of subordinate phase.During restowing, because the transmission speed relevant with input operation is quite high, the acting force of the generation of beating strongly that causes is quite big, feasible output is quite high, and between delivery date on sale, to move relevant transmission speed very slow owing to unload with each goods, and the acting force that produces of beating a little less than causing is very little, make export quite low.The difference of the output level between restowing and selling goods and output signal number are that the count value of article is irrelevant, thus original stock number can by will restow with sell goods during the count value that obtains determine the Calais mutually.At this moment, the stock number before supposing to restow is zero.Unless specialize, otherwise all suppose similar situation in the following description.
In addition, when article are that article in the automatic vending machine and passage are simultaneously as depositing the output of article and article when transmitting shelf, according to the output of piezoelectric sensor or voltage sensitive sensor or microphone, during statistics is restowed the phase one and the goods number that passes through during selling goods of subordinate phase.Article count value that the count value that provides according to counter obtains from experimental result and the corresponding relation between the estimated value are estimated the article number that the phase one passes through during restowing.
Owing to following reason, can adopt this method to estimate the quantity of article.During restowing, because the transmission speed relevant with input operation is quite high, beating strongly of causing applies a sizable acting force (impulsive force or stamping press), because as following description, counting going wrong in forward one side.After the restowing of the phase one that is through with, contact with counter (piezoelectric sensor or voltage sensitive sensor) at the specified point place or the article of the highest point that stops because of the instability contact can be subjected to directly or indirectly in succession to the impact of importing and be deposited in the article on the highest article continuously.Impact to counter applying acting force each time, and cause extra counting.Such error count can not appear at phase one all article inputs after restowing, and such error count to occur be chance and be at random.For example, when acting force perpendicular to or near error count the time just occurring perpendicular to the counter surface, its direction is parallel to or then error count can occur near being parallel to the counter surface.Significant variation appears in the mode of beating when in addition, not only the size of goods acting force but also its direction all can be transmitted by shelf with its weight and goods.So it is uncertain that counter detects beating of goods passage, promptly counter is uncertain to the error count of goods.Owing to be difficult to eliminate such error count, so the quantity of the article by specified point during taking the second best course of action to come according to depending on count value that counter provides the article estimated value that obtains from experimental result and the estimation of the corresponding relation between the count value to restow.
By refilling full shelf with article in the actual automatic vending machine that is suitable for of the present invention, produce the count value of article and the corresponding relation between the estimated value the relation during restowing from the phase one between the variation of count value and the corresponding actual object number.In " embodiment ", describe the special case of this operation below in detail.
During the selling goods of subordinate phase, owing to the quite low transmission speed relevant with moving down of each goods cause a little less than beat, so the error count that may occur during restowing seldom can occur, this count value that makes counter provide is quite reliable.Therefore, the estimated value by goods during will restowing and sell goods during the count value addition that provides of counter, can determine original stock number exactly.
In addition, according to the present invention, when shelf began to fill or almost fill goods, the enable position sensor was with this condition notification operator.So,, can count original stock number according to the type of stock by determining the stock number of filling or almost fill shelf of each cargo type in advance.
The present invention has following excellent effect.
(1) by piezoelectric sensor or voltage sensitive sensor are installed, the counter that the simple structure that does not comprise moving part can be set comes definite exactly quantity by object, has improved cost benefit.Especially, when object passes through sensor, if and be in diagonal positions at short notice or beat and repeatedly apply acting force (impulsive force or surge pressure), sensor output (electric signal) is through signal Processing, thereby only start first output of each sensor, and forbid the every other output that occurs in the predetermined short cycle, thereby prevent the error count that occurs owing to beating.
(2) adopt the article that the invention enables of microphone to count in non-contacting mode.Make the microphone can get rid of as sensor to be damaged, and prevented basically article by during the beat adverse effect of caused a plurality of sound.So, the invention enables the convenience of structure and operation to increase.
(3) will be applied to article in the automatic vending machine by the object count device, the original quantity in stock on the shelf in the automatic vending machine will be counted, and make stock be subjected to appropriate control, and automatic vending machine is normally turned round.
(4) adopt by the experimental data support the practicable, effectively and simple corrective action of the count value estimation article number that provides from counter be provided, can avoid adopting the error count that seldom occurs when the object count device is applied to article in the automatic vending machine passed through of piezoelectric sensor or voltage sensitive sensor.Therefore, the invention enables the article of depositing to be able to appropriate control, and automatic vending machine can normally move.
(5) adopt position transducer, can be simply and determine to fill up or almost fill up the original stock number of shelf exactly.

Embodiment
Embodiments of the invention 1 to 4 are described with reference to the accompanying drawings.Each embodiment illustrates in conjunction with the counting of using stock number in the automatic vending machine.
Before describing accompanying drawing, with reference to Figure 14 traditional general automatic vending machine is described, so that understand description hereinafter.Figure 14 is a kind of like this sectional view of vending machine.Among Figure 14, filling thermal insulation material 33 between shell of opening in the left side 31 and the inner casing 32 does not have the thermal insulation material of label to be filled near in the interior door 14 of opening yet.Goods display part, goods options button and advertising media are positioned at external door 15.Four shelf 7 twist, and (among the figure along side direction) parallel arranged longitudinally, except the inclined lead plate portion (tilted introduction plate portion) that is positioned at machine top, the space in the mode of curling up along vertically extending.Cylindrical articles 9 is to be contained in by this way on the shelf 7, is about to them and piles up, and its axial horizontal direction is extended, and at every turn with article when the shelf bottom is removed, article transmit downwards successively.Below each shelf 7, there is the basis signal of selling goods to transmit the transmission mechanism 20 of article 9.In other words, shelf 7 are used as the output transmission channels of article 9 again both as the storage channels of article 9.The article 9 that transmit descend, push the folding door 17 that links to each other with inside door 14 bottoms open along chute 16, and move to delivery outlet 18.For the inside that makes automatic vending machine remains under the suitable temperature, be provided with the cooler 23 and the heater 24 of selection work, the fan 28 that is used for air circulation and register (not shown).In addition, a machine chamber 29 is arranged at the bottom of vending machine, and condensing unit is installed in the machine chamber, and condensing unit is by compressor 21, the freezing machine 22 that is used to cool off and be used for air cooled fan 27, and these devices are all worked according to the both vapor compression cool cycles.Air cooling fan 27 externally air sucks later on by the air intake 25 that is positioned at external door 15 bottoms and made condenser 22 and compressor 21 coolings by the gas outlet on the rear side 26 before the back of machine discharges.
Fig. 2 is the side view of embodiment 1, provides the peripheral situation of sensor installation site during restowing.Among the figure, the stock number before supposing to restow is zero.When article 9 from the input port 5 when being input to shelf 7 continuously, according to each impulsive force in the passage, from pulse signal of piezoelectric plastics film 1 output, this pulse signal is a numeral output corresponding with the quantity of article 9, among the figure, the white circle of article 9 usefulness is represented (hereinafter being called " phase one article "), the level of storing up piezoelectric plastics film 1 up to article 9.Restow finish after, the article 9 (hereinafter being called " subordinate phase article ") of stamping oblique line are stacked on the article of phase one.Yet the article 9 of subordinate phase do not pass through piezoelectric plastics film 1, so film can not receive their impulsive force, and can output pulse signal.When article 9 and this article 9 when colliding the article 9 of in the subordinate phase deposited front of input in the subordinate phase, this impulsive force is by several article 9 in the front in the subordinate phase and the highest article 9 (being positioned at piezoelectric plastics film 1 place) and be sent to piezoelectric plastics film 1 indirectly in the phase one.Yet,,, prevented counting to this impulsive force so there is not equal output because the level of the impulsive force that transmits indirectly during restowing is lower than the level of the power that has applied when the phase one article have directly passed through film.
Fig. 3 be restow during corresponding relation between the treated output of time and piezoelectric sensor.If timetable is shown as transverse axis, and the output that piezoelectric sensor is treated is expressed as the longitudinal axis, highly is arranged in the transient state time interval time dependent figure corresponding at interval with input time for the signal of H so during restowing.The quantity of the article 9 of phase one is corresponding during restowing among the quantity of pulse signal N1 and Fig. 2, and by processing among Fig. 1 and computing circuit 10 countings.The meaning of term " treated " is, because real sensor output is the pulse signal of level with the impulsive force marked change, so carry out pre-service, makes it to remain on the constant level, and the execution signal Processing, with the error count that prevents that meeting from occurring with collision situation.In other words, Individual Items 9 can be with the diagonal positions collision, or after collision gently knock-on repeatedly apply impulsive force, thereby repeatedly provide output at short notice.If the pulse signal counting number to repeating can go wrong.So, must carry out signal Processing, wherein, only start first pulse, and forbid the repeating signal that all are follow-up.
Describe signal Processing below with reference to Fig. 6, provide the time among the figure and from the corresponding relation between the undressed output of piezoelectric sensor.As shown in FIG., undressed output of piezoelectric sensor or actual output is changed significantly.So, in signal Processing, (1) the threshold value H with regulation is arranged on the constant level, and (2) when in a short cycle repeatedly (among the figure, have two signals to surpass threshold value H) when repeating an impulsive force, only start first signal that surpasses threshold value H, but forbid other signals (among the figure being) of order output in the appointment short cycle (a) corresponding with a dead time.Usually, impact and in a short cycle, can repeat repeatedly, but in fact, have only two outputs 7 to have the level that often surpasses threshold value H, and this level descends fast from the 3rd output.This signal Processing is to be carried out by processing among Fig. 1 and computing circuit 10, carries out pre-service simultaneously, level is remained threshold value H, and add up afterwards to determine the quantity by article.
Fig. 4 be sell goods during the side view of outside, sensor installation site.Among the figure, when selling article 9, it is mobile that the shade article 9 among Fig. 2 in the subordinate phase are transmitted downwards by gravity successively.During weight transfer, the impulsive force (see figure 2) that the power that the article 9 in the subordinate phase are applied by article 9 in piezoelectric plastics film 1 applies than the phase one by member 8 is more weak, piezoelectric plastics film 1 is according to impacting more low level pulse signal of output a little less than this.When sell with subordinate phase in during the article 9 of similar number, in this pulse signal ends subordinate phase to the counting of article 9.The counting of article 9 in the subordinate phase is described below with reference to Fig. 5.
Fig. 5 describes be sell goods during corresponding relation between the treated output of time and piezoelectric sensor.As time goes on, the level L pulse signal that is lower than level H among Fig. 3 be arranged in and sell goods instantaneous time at interval time corresponding at interval in.The pulse number N2 of level L is corresponding to the quantity of the article 9 that have shade in the subordinate phase among Fig. 2 and Fig. 4.By the counting of processing and computing circuit 10 execution number N2, and pulse signals is carried out pre-service and signal Processing.Among Fig. 3 and Fig. 5 pulse signal number N1 and N2 with N1+N2 be original stock number.Finish restow after, the counting of N1 finishes, and stops the counting of N2 when finishing finishing when restowing not the selling goods of article 9 (subordinate phase among Fig. 2) that applies impulsive force to piezoelectric plastics film 1.
Fig. 7 of following main reference article depicted counting operation also replenishes with reference to the method for Fig. 2 to 6 description of having described according to the definite original stock number of first embodiment.At step S1, input port (input port 5 among Fig. 2) opened and refilled article (being undertaken by pushing Yishanmen (not shown) open).At step S2, make the article number (i) in the phase one be initially set to zero, and judge at step S3 whether piezoelectric sensor (seeing the piezoelectric plastics film 1 among Fig. 2) has output H (see figure 3).If judged result is a "Yes", then process enters step S4, and if the result is a "No", then process enters step S7.At step S4, make (i) increase " 1 " (promptly in (i), adding " 1 "), to determine aggregate-value by number of articles.At next procedure S5, timer T picks up counting from 0, and at step S6, process is waited for first output H, surpasses the short cycle (a) (dead time) of an appointment up to T, promptly up to through the dead time (a).Subsequently, process turns back to step S3.Execution in step S5 and S6 are with the error count that prevents to be caused by repeated impulsive force with the knock-on of the relevant Individual Items of collision owing to as shown in Figure 6.These steps have been forbidden those output H that meeting occurs in the dead time (a).Repeat process subsequently, to determine the cumulative number by number of articles at step S4 from step S3 to S6.Judge input port whether closed (restow and whether finish) at step S7.If the result who judges is a "No", then still to carry out and restow, process turns back to the state of step 3 front.If the result is a "Yes", then to restow and finish, process enters following step S8, and this is one and determines during restowing the process of the cumulative number of article in the phase one.The cumulative number of article in the subordinate phase during later step is determined to sell goods.
At step S8, (j) that represents the goods number in the subordinate phase is initially set to zero, and judges whether to exist the signal S that sells goods at step S9.If exist, then judge whether to exist output L (see figure 5) at step S10.If the result who judges is sure, then process enters step S11, makes (j) increase 1 (making (j) increase " 1 "), so that determine the accumulated value by the article number.Subsequently, process is returned step S9 state in the past.After step S11, need a processing procedure, to prevent that Individual Items from repeatedly producing impulsive force and causing as shown in Figure 6 error count.In other words, need an output L who forbids in the dead time (a), may occurring.Yet in fact, because that the time is enough to is longer than the dead time (a), and process is waited for the next one signal S that sells goods at step S9, so this process is omitted.
If the judged result at step S10 negates that then whether no matter exist the signal S that sells goods all not export L, this just means that all article in the subordinate phase have all passed through piezoelectric sensor.Then, at step S12, determine original stock count Z (=N1+N2) so that finish series of steps to the stock counting number.The end value of N1=(i+1), and the end value of N2=(j+1).
Describe second embodiment below with reference to Fig. 8, Fig. 8 is the side view of outside, sensor installation site.What the difference of second embodiment and first embodiment was to adopt is pressure sensitive elastomer 2 rather than piezoelectric plastics film 1 shown in Figure 1, and pressure sensitive elastomer 2 is attached on the surface of member 8.Pressure sensitive elastomer 2 is voltage sensitive sensors of being made up of a kind of like this material, when article 9 by the time act directly on the local time of material, this a part of resistance can become (surge pressure) according to direct acting force.In other words, direct acting that part of article is an electrical isolation when beginning, but is conducting electricity by becoming later on.In the output of pressure sensitive elastomer 2 by handling and after computing circuit 11 converts electric signal to according to the resistance of rubber or conductance, identical described in pre-service, signal Processing and the execution that adds up such as first embodiment.
In first and second embodiment, when the article number that passes through during restowing in piezoelectric plastics film (piezoelectric sensor) 1 or pressure sensitive elastomer (voltage sensitive sensor) 2 are used for to the phase one is counted (count value is corresponding with N1 among Fig. 7), as described below, can error count appear at forward in fact.Description will be carried out in conjunction with first embodiment and with reference to Figure 11 (a) with (b).Figure 11 (a) has described that the highest article contact with piezoelectric sensor 1 fully and has finished the state that restows in the phase one when stopping.Figure 11 (b) describes is the article of the highest point states when stopping with unstable contact the in lower end of piezoelectric sensor 1.The article (dotting) that come one after another input and be deposited on the highest point article directly and indirectly apply impulsive force to the article of highest point, and the article of highest point apply acting force to piezoelectric sensor 1 again, thereby produce unnecessary counting.Such error count seldom occurs for the article of input after restowing in the phase one, dot among the figure, and it occurs being at random.For example, the direction that error count occurs in acting force is vertically or almost perpendicular to the timer surface time, and it is parallel or when almost being parallel to the timer surface can not appear at its direction.In addition, be not only the size of article acting force and be that the mode that the direction of acting force is beated all can transmit with weight with by shelf the time has significant change.So, timer whether detect article by the time beat whether error-detecting is uncertain to article.Owing to be difficult to eliminate such error count, so the best number of articles of passing through during second course of action estimated to restow in the phase one of getting as described below.
Figure 12 describes is count value (piezoelectric sensor 1 provides) during restowing and the corresponding relation between the corresponding article estimated value, and the count value during restowing is 14 or more hour, the quantity survey (surveying) of article is 11.Similarly, when the count value during restowing was 15 or 16, the quantity survey (surveying) of article was 13, and the count value during refilling is 17 or when bigger, the article number that passes through is estimated as 16.This corresponding relation is determined according to following experimental result.
Figure 13 describes be restow in the phase one during relation between the variation of the actual number of article and count value, this determines by repeatedly refilling shelf 7, when determining at each type of items in the automatic vending machine.The left side one row provide the title of product, the variation of count value during middle row provide and restow, and row on the right provide the actual number of article.For example, for product A (Real Gold (trade (brand) name)), count value changes between 17 and 18, and the actual number of article is 16.To product B, C, D ..., shown in the variation of article count value of K (omitting actual name) and the relation between the corresponding actual number see Table.In the table, all count values are all above corresponding article actual number, and the article that expression is imported successively and is deposited on the article of highest point directly and indirectly apply acting force (seeing Figure 11) to the article of highest point.As shown in figure 12, according to these data, the actual quantity of article is divided into 11,13 and 16 3 groups, and determines the respective change scope of count value subsequently, so that do not repeat mutually.Although the estimation number of the article that obtain in the corresponding relation from Figure 12 is reasonably supposed to comprise mistake, but importantly this method is placed on the basis of " corresponding relation between the count value of article and the estimation number " that draw according to experimental data, so that from the count value that changes owing to inherent uncertain factor, estimate the quantity of article as far as possible exactly.
Fig. 9 is the side view according to the outside, sensor installation site of the 3rd embodiment.According to this embodiment, near having installed one on the member 8 of input port 5 such as according to pass through and the idiophonic sound producing body 4 of output sound of article 9, and face the microphone 3 that sound producing body has been installed.The description that connects the electronic circuit of microphone 3 is omitted.Sound producing body 4 can be combined with member 8 by the processing section of member 8.So the counting of the article 9 by sound producing body 4 is to carry out according to the output of microphone 3.According to the 3rd embodiment, in the phase one, the article 9 by sound producing body 4 during restowing are counted, and in subordinate phase, with the same among first and second embodiment, count the article 9 that pass through by sound producing body 4 and during restowing the back to selling goods.With the count value addition that obtains in each stage, to determine original quantity in stock.According to the 3rd embodiment, article 9 by the time collision sound producing body more than 4 time of beating, cause repeatedly sounding.Yet because the performance of microphone 3, it is a sound that these sounding only detect, thereby need not to carry out signal Processing, wherein, only start first output, and later output is under an embargo all, this with first embodiment and second embodiment in be the same.
Describe the 4th embodiment with reference to Figure 10, Figure 10 is the side view of outside, sensor installation site.Among the figure, pressure sensitive elastomer 2A is installed near on the corbel back slab 6 of input port 5, and testing circuit 12 is connected on the rubber 2A.The position of pressure sensitive elastomer 2A is corresponding with the extreme higher position of the article 9 that fill up or almost fill up shelf 7.The method that the received pressure number of times of sensor is counted when each article 9 are by sensor during transmitting according to second embodiment is opposite, and pressure sensitive elastomer 2A is the position transducer according to the existence of its pressure detection article 9.In other words, when being filled up or almost filling up by article 9 when shelf 7 beginning, this is to transmit information by the output as the pressure sensitive elastomer 2A of position transducer.So the quantity of the article of storing when in advance determining that for each type of items shelf 7 are filled or almost fill up 9 can be counted the original stock number of each type of items.In addition, be that top from the figure right side rack is installed on the 3rd member 8 as the testing circuit 12 of the pressure sensitive elastomer 2B of another location sensor and rubber 2B.This sensor is used for that notifying operation personnel shelf have soon filled up during restowing, the operation of being convenient to restow of this information signal.
