Figure 19 is the stereographic map that the radicle periphery of conveyer mechanism 52b is amplified, and Figure 20 is the longitudinal section that the radicle week edge throughput direction A of conveyer mechanism 52b is blocked.

As shown in Figure 19 and Figure 20, butt side at conveyer mechanism 52b, arrange and link gear 90, follower gear 104, driven roller 96, jockey pulley 106 and help roll 108, wherein, above-mentioned link gear 90 comprises the linking part 92 that the rotary body 62 with driver element 50 non-rotatably links, above-mentioned follower gear 104 is by the driven rotation with linking gear 90 engagements, and be the direction with direction of principal axis O quadrature by the direction transformation of the rotary driving force of rotary body 62, above-mentioned driven roller 96 links with one heart in the side of follower gear 104, mentioned strain roller 106 is arranged on the place ahead of driven roller 96 and is positioned at below, travelling belt 56 is applied to tension force, above-mentioned help roll 108 makes the moving direction of travelling belt 56 crooked upward below driven roller 96.

Figure 21 watches from front side the stereographic map that links gear 90, and Figure 22 watches the stereographic map of the link gear 90 shown in Figure 21 from rear side.Figure 23 means the cross-sectional perspective view of the longitudinal section that the link gear 90 shown in Figure 21 is blocked along throughput direction A.In addition, owing to linking the construct for handling of gear 90 with respect to rotary body 62, roughly the same with the construct for handling of the connecting piece 64 of the 52a of conveyor screw mechanism, therefore for playing part same or said function and effect with connecting piece 64, mark same Reference numeral, detailed.

As shown in Figure 21～Figure 23, link gear 90 comprises that the crowngear in the large footpath of meshing with follower gear 104 is gear part 110, be less than gear part 110 with diameter and arrange with one heart with this gear part 110, side-prominent cylindric linking part 92 inwards on the same axle of direction of principal axis O with rotary body 62, by linking part 92, can be with non-rotatable state with respect to the installation portion 80(80a, the 80b that are arranged on the rotary body 62 of driver element 50) lock and removal.That is, linking gear 90 is self-driven unit 50(rotary bodies 62 in the future) rotary driving force be delivered to the driven wheel of follower gear 104 and driven roller 96.

Linking part 92 with the linking part 78(of connecting piece 64 that forms the 52a of conveyor screw mechanism with reference to Figure 10～Figure 13) be same structure roughly, comprise cylindrical portion 78a, the teat 78b of a plurality of semi-cylindrical form that the mode of joining with the back side with gear part 110 at the outer peripheral face of cylindrical portion 78a forms along Zhou Fangxiang, the upper and lower a pair of engaging teat 78c of elastically deformable, 78c, catch 78d, the pin 78e of shape portion, with pair of right and left pinch hand 78f, 78f, engaging teat 78c and pinch hand 78f have formed for removing the releasing operating portion 82 of the installment state of 80 of the link linking part 92 of gear 90 and the installation portions of rotary body 64.

Like this, link gear 90 and comprise with the linking part 78 of the connecting piece 64 of the 52a of conveyor screw mechanism thering is the roughly linking part 92 of same structure, so conveyer mechanism 52b and driver element 50, have identical construct for handling with the situation of the above-mentioned conveyor screw 52a of mechanism having illustrated by Figure 18, its installation action and removal action are also same.

As shown in Figure 19 and Figure 20, follower gear 104 has the gear part 104a of the crowngear meshing with the gear part 110 that links gear 90, for axle, be bearing in the driven roller 96 between left and right sidewall 100a, the 100a of travelling belt matrix 100, by making follower gear 104 and one distolateral chimeric coaxial, thereby make this follower gear non-rotatable with respect to driven roller 96.Thereby, when linking gear 90 drived units 50, take direction of principal axis O and as axle center, be rotated while driving, it is the driven rotation of axis of rotation that follower gear 104 be take with the direction of principal axis O1 of this direction of principal axis O quadrature on the surface level that comprises direction of principal axis O, makes thus driven roller 96 take direction of principal axis O1 as axle center rotation.Now, on travelling belt 56, be formed with along the moving direction of travelling belt 56 side by side and lay respectively at a plurality of pilot hole 56b of portion of Width both end sides.Therefore, the 56b of pilot hole portion engages with a plurality of positioning salient 96a that the Width both end sides of outer peripheral face at driven roller 96 forms along Zhou Fangxiang, thereby travelling belt 56 can not slided on the outer peripheral face of driven roller 96, can realize stable movement.

Figure 24 means the stereographic map of the movable base 112 of jockey pulley 106 and this jockey pulley 106 of supporting.

As shown in Figure 19, Figure 20 and Figure 24, jockey pulley 106 the downstream of the throughput direction A of driven roller 96 and be positioned at driven roller 96 below position on by movable base 112 axles, supported, on the upper surface 100b and the position between driven roller 96 of travelling belt matrix 100, travelling belt 56 is pressed to the oblique back lower place, thereby formed the tension mechanism that travelling belt 56 is applied to the tension force of expectation.

Movable base 112 is can, along the mode of slip before and after throughput direction A, being arranged on the inside surface of the upper surface 100b of the travelling belt matrix 100 that the conveyor surface 56a of travelling belt 56 is supported.Jockey pulley 106 is bearing in between outstanding pair of right and left supporting arm 112a, the 112a in the oblique back upper place of butt side direction of movable base 112 by the rotatable earth's axis, by this movable base 112 can before and after slide.Can be clear and definite according to Figure 20, jockey pulley 106 is arranged on than the driven voller of front 98 and more approaches on the position of driven roller 96 of butt side, in other words, from above watch the vertical view of conveyor surface 56a of travelling belt 56, jockey pulley 106 is configured in its part position overlapping with driven roller 96.Thus, can be on the conveyor surface 56a of travelling belt 56 taking in of commodity G do not had to contributive bosom portion near jockey pulley 106 is set, can fully guarantee the commodity amount of conveyer mechanism 52b.

It is side-prominent to butt that movable base 112 forms supporting arm 112a, and the cross section of front and rear surfaces and the lower surface opening shape of " Contraband " shape roughly.Movable base 112 is formed with the slotted hole 112b of fore-and-aft direction by rear in Width central authorities, in the surrounding of slotted hole 112b, be formed with a plurality of (in Figure 24 being 4) roughly L hole 112c of L shaped shape.Slotted hole 112b is inserted perforation by outstanding supporting slice 100c that can be outstanding from the upper surface 100b vertical of travelling belt matrix 100, and each L hole 112c can be inserted and connect (with reference to Figure 20 and Figure 24) from outstanding each protrusion tab 100d of the upper surface 100b vertical of travelling belt matrix 100.Thus, movable base 112 can be under the guiding function of slotted hole 112b and L hole 112c and the outstanding supporting slice 100c of hole portion and protrusion tab 100d, at front and back upward sliding.

And, being arranged between the supporting slice 112d of front and the outstanding supporting slice 100c of the travelling belt matrix 100 that insertion connects slotted hole 112b of movable base 112, volute spring 114 is installed.Volute spring 114 is to make the rearward relatively extension spring of (opposite direction of throughput direction A) application of force of movable base 112 with respect to travelling belt matrix 100.By the acting force of this volute spring 114, movable base 112 is installed on travelling belt matrix 100 under rearward by the state of elastic force-applying,, jockey pulley 106 is pressed to oblique back lower place elasticity the conveyor surface 56a of travelling belt 56 between the upper surface 100b of travelling belt matrix 100 and driven roller 96, this travelling belt 56 is applied to the tension force of expectation.

As shown in figure 20, help roll 108 is arranged on the below of driven roller 96, for the lower face side at travelling belt matrix 100 and throughput direction A travelling belt 56 side shifting, after commodity G is sent inwards abreast, make it crooked and return upward towards driven roller 96, this help roll 108 is bearing between left and right sidewall 100a, the 100a of travelling belt matrix 100 by axle.Also help roll 108 can be configured to obtain to rear side more, form the structure of position that help roll 108 is configured in the upstream side of travelling belt 56.

Like this, in the conveyer mechanism 52b of this commodity device 10, be arranged at the driven roller 96 rotariling actuate under the upstream side of throughput direction A and the effect at the rotary body 62 of driver element 50, and the travelling belt 56 that has been arranged between the driven voller 98 in downstream of throughput direction A ring-type tenter, and on the position that more approaches driven roller 96 than driven voller 98, be provided with the jockey pulley 106 that travelling belt 56 is applied to tension force.; in conveyer mechanism 52b; in the inboard that approaches the goods shelf 28 of driver element 50, driven roller 96 and jockey pulley 106 are set; front side at the goods shelf 28 that commodity G is discharged to outside arranges the driven voller 98 that front and back position does not change; the position stability that therefore can make commodity G discharge from front side, can stably discharge commodity G to outside.And, from the Poewr transmission mechanism of driver element 50 transferring power, can only be configured in the inboard of goods shelf 28, so need to be from inboard to the Poewr transmission mechanism of front side transferring power, can realize simple and compact structure, reliably travelling belt 56 is applied to necessary tension force, can more stably to commodity G, carry simultaneously.

In addition, in conveyer mechanism 52b, as shown in figure 20, the direction of principal axis O that the conveyor surface 56a of travelling belt 56 is arranged on the central shaft that is compared to rotary body 62 is the position of below more, direction of principal axis O1 as the central shaft of driven roller 96 is arranged on the surface level of the direction of principal axis O that comprises rotary body 62, jockey pulley 106 is arranged on the downstream of the throughput direction A that is positioned at driven roller 96 and than on the position of driven roller 96 belows, and, below driven roller 96, setting makes the travelling belt 56 that extends in parallel from driven voller 98 and throughput direction A towards driven roller 96 crooked help roll 108 upward, make thus travelling belt 56 by L word shape roughly, move under side view.

Thereby, transmission of power from the rotary body 62 of driver element 50 to the driven roller 96 that travelling belt 56 is moved, can only carry out on the height and position with the direction of principal axis O level of this rotary body 62 from linking gear 90 to the transmission of power of follower gear 104, can make the configuration of above-mentioned link gear 90, follower gear 104 and driven roller 96 and gear engagement structure become simple.In addition, by driven roller 96, jockey pulley 106, travelling belt matrix 100 and help roll 108, butt side at conveyer mechanism 52b forms travelling belt 56 spatial structure that is roughly L word shape under side view, and by conveyor surface 56a be configured in than the direction of principal axis O1 of driven roller 96 more below, the height and position that can make thus conveyor surface 56a on the whole height of this conveyer mechanism 52b is alap position, can control the size in whole short transverse, guarantee to greatest extent the configuration space of the commodity G on conveyor surface 56a simultaneously.

In other words, installed in the goods shelf 28 of conveyer mechanism 52b, although want the conveyor surface 56a of travelling belt 56 to be arranged on alap position in order to guarantee to greatest extent the accommodation space of commodity G, but also step-down of the position of driver element 50 correspondingly, so goods shelf 28 maximization that self becomes downwards, so need to be configured in top to a certain degree with respect to conveyer mechanism 52b by driver element 50.Therefore, in conveyer mechanism 52b, the position of improving driven roller 96 with respect to travelling belt matrix 100, under above-mentioned side view under the spatial structure of L word shape by travelling belt 56 tenters, thereby can reduce the position of conveyor surface 56a, and simplify the power transmission structure from rotary body 62 to driven roller 96, control the whole height of goods shelf 28.

Then to selling out the concrete structure of testing agency 66, describe.

As shown in Fig. 5 and Fig. 7, selling out testing agency 66 is such mechanisms,, utilization under the effect of conveying mechanism 52 together with commodity G mobile detection part 68, the 102 and coupling components 70 to driver element 50 is set from base component 58, to detector switch 86(with reference to Figure 15) connect (ON) operation, thereby the commodity G that detects end is discharged from, and no longer has commodity G on this goods shelf 28, and commodity G sells out this situation.Wherein, as conveying mechanism 52, in the situation that use the 52a of conveyor screw mechanism in the situation that and use conveyer mechanism 52b, make when the commodity G at end is discharged from coupling components 70 slide the shape of mobile detection parts 68 and detection part 102 different, for roughly the same structure, below for the situation of detection part 68 of the application 52a of conveyor screw mechanism, be that example describes selling out testing agency 66.

Figure 25 is that Figure 26 means the stereographic map of selling out testing agency 66 included tilting member 72 and coupling components 70 for the part omission stereographic map of the structure of selling out testing agency 66 is described.In addition, Figure 27 means the stereographic map of watching tilting member 72 from rear side.

As shown in Fig. 5, Fig. 7, Figure 25 and Figure 26, sell out testing agency 66 and comprise the detection part 68(102 being arranged on conveying mechanism 52), in the side of base component 58 along throughput direction A extend, by detection part 68(102) the rectangular bar-shaped coupling components 70 that slides, and be arranged on tilting member 72 and the detector switch 86 in driver element 50.; sell out in testing agency 66; that for the conveyor screw 54 of the rotation number ,Ji conveyor screw 52a of mechanism of rotary body 62 of driver element 50 or the conveying of 56 couples of commodity G of travelling belt of conveyer mechanism 52b action (feed status), detects detects the detector switch 86 with switch as automated movement, is also used as and sells out the switch that detects use.

As shown in Fig. 5 and Fig. 7, detection part 68(102) be arranged on the behind of the commodity G that is positioned at end among the commodity G arranging on goods shelf 28, can on throughput direction A, move together with commodity G.And, when the commodity G at end is by when goods shelf 28 is discharged, be formed on above-mentioned detection part 68(102) the basifacial press section 68a(102a of a side) in the position, forefront of goods shelf 28 by the rear side of the front end face 70a of coupling components 70 forwards (front side) press and make it and slide.

As shown in figure 26, coupling components 70 comprises front end face 70a, be arranged on the rear of this front end face 70a, the first protrusion tab 70b giving prominence in the horizontal direction to the inner side of base component 58, the the second protrusion tab 70c that be arranged on long side direction substantial middle, gives prominence in the horizontal direction to the inner side of base component 58, be arranged on butt side, to the inner side of base component 58 outstanding the 3rd protrusion tab 70d in the horizontal direction, and be arranged on butt, rearward outstanding and form the pressing tablet 70e that is roughly L word shape under side view after bending upward.

The first protrusion tab 70b, the second protrusion tab 70c and the 3rd protrusion tab 70d, the not shown slip slotted hole forming with lateral opening at base component 58, extend along throughput direction A engages with state movably, guides the sliding action of this coupling components 70.Now, on the second protrusion tab 70c, and base component 58 between not shown volute spring is installed, thereby make coupling components 70 with respect to base component 58 rearward relatively (opposite direction of throughput direction A) be applied in power.The butt of pressing tablet 70e be formed with can with the dip plane 70f of the dip plane 72a sliding contact of tilting member 72.

As shown in Figure 14 (A) and Figure 25～Figure 27, tilting member 72 is under front elevation, to be configured to the plate-shaped member of general triangular shape, from the outstanding pivot pin 47 of the positive face shield 46a of housing 46, is inserted into and runs through near be formed on leg-of-mutton upper vertex axis hole 72b(with reference to Figure 14).Thereby it is rotation center that tilting member 72 be take the direction of principal axis O2 of pivot pin 47, can be rocked to θ 3 directions and θ 4 directions (with reference to Figure 25) on the positive 50a of driver element 50.

Tilting member 72 outstanding be arranged at its just basifacial supporting slice 72c with give prominence between the pin 49 that is arranged at positive face shield 46a volute spring 116(is installed with reference to Figure 14 (A)), the direction of principal axis O2 of take is thus applied in power (can in the lump with reference to Figure 28 (B)) as rotation center towards θ 4 directions (ON direction) of leaving from rotary body 62.But, at the detected parts 68 of coupling components 70, forwards slide forcibly conventionally during (during non-selling out), under the state that the dip plane 72a that is formed at one sidepiece of tilting member 72 rearward presses at the dip plane of coupled parts 70 70f, engage with each other with this dip plane 70f, thereby be maintained at the state (can in the lump with reference to Figure 28 (A)) that is rocked to θ 3 directions (OFF direction) that approach rotary body 62.

As shown in Figure 25 and Figure 27, side-prominent inwards from the side of tilting member 72 have a pressing lever 72d.Pressing lever 72d be at tilting member 72 because the acting force of volute spring 116 is when connecting (ON) direction and swing, the test rod 86a by its side pressing detection switch 86 makes it to swing, thereby presses the button the arm of 86b.

Then, selling out of selling out that testing agency 66 carries out being detected to action mainly describes with reference to Figure 28.

Figure 28 means by selling out the commodity G of testing agency 66 and sells out relation that the automated movement that detects action and rotary body 62 detects action and sell out and detect the plane key diagram that action describes selling out the commodity G of testing agency, Figure 28 (A) means the figure of the state that commodity G does not sell out, Figure 28 (B) means the figure that the state that commodity G sells out detected, and Figure 28 (C) means by detector switch 86 and the figure that the state of automated movement has occurred rotary body 62 detected.

First, as shown in Figure 28 (A), on goods shelf 28, remain commodity G, the detected parts 68(102 of coupling components 70) forwards slide conventionally during (during non-selling out), the dip plane 70f of coupling components 70 is rearward applied power, and the dip plane 72a of tilting member 72 is rearward pressed by the dip plane 70f of above-mentioned coupling components 70, the two engages with each other under such state (can in the lump with reference to the solid arrow in Figure 26), therefore from dip plane 70f, be subject to going to the pressing force of θ 3 directions, resist the acting force of volute spring 116 and remain on the position that swings to disconnection (OFF) direction.Under this state, the pressing lever 72d of tilting member 72 is positioned at the position away from the test rod 86a of detector switch 86, or arrive can make test rod 86a press the button 86b and make detector switch 86 connect the position of (ON) operation before, the position that can not press this test rod 86a, so detector switch 86 is for disconnecting (OFF).

When from this state, the commodity G at the end of goods shelf 28 is discharged from, the detected parts 68(102 of coupling components 70) while forwards sliding (while selling out), as shown in Figure 28 (B), the fastening state of the dip plane 72a of tilting member 72 and the dip plane 70f of coupling components 70 is disengaged, the pressing force of going to θ 3 directions from dip plane 70f disappears, the 70f sliding contact of 72aYu dip plane, dip plane, tilting member 72 is swung to connecting (ON) direction (θ 4 directions) by the acting force of volute spring 116 simultaneously.Thus, the test rod 86a of the pressing lever 72d pressing detection switch 86 of tilting member 72 and it is swung to the inside, by this test rod, 86a presses the button 86b, so detector switch 86 becomes connection (ON), and this connection (ON) operation is detected by master controller 32.Thereby for this goods shelf 28 that commodity G detected and sold out, master controller 32 is judged as this numbering and sells out, and notifies buyer by the pilot lamp etc. of selling out of operation inputting part 26.

In addition, for the goods shelf 28 of selling out being detected, when operator's fill-ins G of automatic vending machine 12, make detection part 68(102) again move and be set to the behind of the commodity G at end, thus make the state during coupling components 70 and tilting member 72 revert to not selling out shown in Figure 28 (A).

On the other hand, sell out in the included detector switch of testing agency 66 86, by the cam part 88a by rotary body 62,88b, test rod 86a and button 86b are operated, be also used to the rotation number of rotary body 62, be the control (discharge and control) of the conveying of 52 couples of commodity G of conveying mechanism.

; as shown in Figure 28 (C); when rotary body 62 rotates because of motor 44; be arranged on the 88a of pair of cams portion, the 88b of its circumference when the every rotation half cycle of this rotary body 62; the test rod 86a of pressing detection switch 86 and make it to swing, presses the button 86b detector switch 86 is connected to (ON) operation successively.Therefore, master controller 32 sequential chart according to the rules drives motor 44, when each detector switch 86 has been performed 2 connections (ON) operation, detect rotary body 62 and carried out once rotation, rotation number based on this rotary body 62 detects, and controls the action that conveying mechanism 52 is discharged commodity G one by one.

Herein, can be clear and definite according to Figure 28 (A) and Figure 28 (C), on goods shelf 28, remain commodity G, the acting force of tilting member 72 opposing volute springs 116 and be maintained under the state of the position that is rocked to θ 3 directions (OFF direction) the test rod 86a(button 86b of the pressing lever 72d of tilting member 72 and detector switch 86) between formed enough gaps.; the cam part 88a of rotary body 62,88b carry out pressing operation to test rod 86a by this gap simultaneously; therefore when being rotated the rotation number detection of body 62 by cam part 88a, 88b, the pressing lever 72d that sells out the included tilting member of testing agency 66 72 can not become obstruction.That is, the pressing lever 72d of cam part 88a, 88b and tilting member 72 is configured on the position that can not produce each other interference.

On the other hand, as shown in Figure 28 (B), when commodity, G sells out, when the pressing lever 72d of tilting member 72 connects (ON) operation to detector switch 86, if cam part 88a, 88b are positioned at, detector switch 86 is connected on the position of (ON) operation, both may produce interference, cause carrying out the normal action that detects.

For this reason, referring to Figure 29, the 32 pairs of motor 44(rotary bodies 62 of master controller as control device being described) rotation carried out controls.Figure 29 means the sequential chart of the relation of the rotation amount (rotation number) of rotary body 62 under the effect of motor 44 and detector switch 86, has represented the relation of the rotation amount of rotary body 62 and the connection (ON) of detector switch 86 operation.

As shown in figure 29, in the commodity device 10 of present embodiment, master controller 32, for example by detecting d1～d3, detecting cam part 88a, the 88b shown in d3～d5 to the connection of detector switch 86 (ON) operation, detects t1～t3, rotation in 1 week of the rotary body 62 shown in t3～t5 constantly constantly.For example, during moment t1～t2, rotary body 62 has carried out half cycle rotation, if detect d1, is connection (ON) operation that cam part 88a carries out, and detects connection (ON) operation that d2 represents that cam part 88b carries out.

Herein, can be clear and definite according to Figure 29, in present embodiment, during the connection of carrying out at cam part 88a, 88b (ON) operation, there is the half cycle rotation of rotary body 62 or the switching instant of rotation in 1 week.For example, by cam part 88b, at detection d3, carrying out connecting after (ON) operation, through for example 500 milliseconds of stipulated time T() after stop motor 44, thus, the moment t3 of the switching instant of rotating for 1 week as rotary body 62 (for half cycle rotation too), finishes than detecting the slow stipulated time T of d3.Herein, cam part 88a, 88b are provided with a pair of, therefore this stipulated time T is set to the scope of the half cycle rotation that is less than rotary body 62, for example in the situation that cam part is only 1, can be set as being less than the scope of rotating for 1 week of rotary body 62, in the situation that cam part is 3, can be set as being less than the scope of rotating for 1/3 week of rotary body 62.

That is, in commodity device 10, cam part 88a, 88b connect (ON) operation intermittence during, make rotary body 62 be further rotated the sequential control (over-rotation action) of stipulated time T.Therefore, for example at commodity G, in cam part 88b, detector switch 86 is connected under the setting that moment of detection d3 of (ON) operation is discharged from, this detection d3 and on once cam part 88a detect the moment between d4, by still rotation 62 pairs of conveying mechanisms 52 of rotary body drive.Thereby, when detecting in the situation of commodity that commodity G that the moment of d3 discharges is end, at this, detect the moment between d3 and the next d4 of detection, detection part 68(102) coupling components 70 is forwards slided, so by the swing to connection (ON) direction of tilting member 72, detector switch 86 is performed connection (ON) operation, commodity G detected and sells out (with reference to the detection d0 shown in dotted line in Figure 29).That is, in commodity device 10, by carrying out such sequential control, can prevent reliably the interference of cam part 88a, 88b and pressing lever 72d, can be accurately and stably detect the rotation amount of rotary body 62 and selling out of commodity G.

Like this, in this commodity device 10, be provided with at least and in the time of 1 week, connect (ON) operation in the every rotation of rotary body 62, thereby can detect the detector switch 86 of the conveying action of 52 couples of commodity G of conveying mechanism, and be provided with in the situation that on commodity transport path 48, be accommodated in the commodity G at rear be discharged to outside detector switch 86 is connected to (ON) operation sell out testing agency 66.Thus, the automated movement that can use a detector switch 86 to carry out motor 44 detect and commodity G sell out detection, so can reduce the cost of this commodity device 10, the while is detected selling out of commodity G reliably.

Now, sell out testing agency 66 under the control of the master controller 32 as control device, execution cam part 88a, 88b carry out automated movement detection during the moment in make rotary body 62 be further rotated the over-rotation action of stipulated time T, thereby can be in the moment that can prevent reliably the interference of cam part 88a, the 88b of rotary body 62 and the pressing lever 72d of tilting member 72, sell out detection, so can easily a detector switch 86 be used for to automated movement, detect and sell out detection.

In addition, the utility model is not limited to above-mentioned embodiment, certainly can in the scope that does not depart from its purport, freely change.
