As shown in Figure 1, the substrate 2 of commodity carrying out device 1 is provided with peristome 3, on this peristome 3, utilizes substrate 2 and axle to be supported on the pin 6,7 on the bearing components 12,13 and rotates and to be provided with upper footboard 4 and the following pedal 5 that commodity are taken out of control usefulness freely.Peristome 3 rising woods of substrate 2 are provided with and are used for pushing commodity G to aftermentioned commodity export channel plate 100 sides and carry out the guiding protuberance 2a of ability of posture control (with reference to Fig. 7 etc.).

Instantly pedal 5 becomes closed condition, falls down when taking out of from following several the 1st commodity G, and upper footboard 4 supportings are from several the 2nd commodity G (with reference to Figure 11) down, and integrally formed by resin (such as polyacetal).This upper footboard 4 is subjected to being contained in the application of force towards closing direction of being turned round volute spring 8 on the pin 6.

In addition, as Fig. 1～shown in Figure 4, the pin-and-hole 4a of upper footboard 4 connects to insert pin 6 usefulness.The braking surface 4e effect of brake(-holder) block 4b is, when the maximum opening of upper footboard 4 and pin 22 butts and be subjected to acting on commodity load on the upper footboard 4, with the locking position of this upper footboard 4 at maximum opening.Guide plate 4c establishes apart from the interval (than the big interval of the diameter of pin 22) of brake(-holder) block 4b regulation is upright, when link component 19 is reciprocating, forms the sliding tray 4d that pin 22 slides with brake(-holder) block 4b.

So, establish guide plate 4c and brake(-holder) block 4b is based on following reason so that the interval of regulation is upright.That is, when the locking of the state of opening of removing upper footboard 4, if cut off energising to solenoid 17, then link component 19 retracts downwards because of the elastic force of the spring 30 of elongation state.At this moment, be positioned at the pin 22 of upper footboard 4 braking surface 4e, though caught by sliding tray 4d in the back of conflicting with guide plate 4c, owing to be formed with the interval of regulation from braking surface 4e to guide plate 4c, pin 22 just conflicts with guide plate 4c with the impulsive force greater than the occasion that is not formed with this interval.

Because this impulsive force is to the directive effect with upper footboard 4 closures, so by utilizing this impulsive force, and can combine with the elastic force of being turned round volute spring 8 and rapider and reliably with upper footboard 4 closures.Especially, be absorbed in the occasion of upper footboard 4 at commodity because of variable load etc., upper footboard 4 becomes the obstacle that returns the holding state action, but owing to have impulse force by giving the return action that above-mentioned impulsive force makes upper footboard 4, so be absorbed in disengagement from above-mentioned, turn back to holding state reliably.

In addition, the effect of formed yielding groove 4f is, upper footboard 4 close state the time pin 22 run into upper footboard 4 and do not hinder closed action.Claw 4g forms: when making up when the commodity carrying out device 1 with same member when being provided with, the upper footboard 4 of this relative commodity carrying out device 1 intermeshes when closure state, and rests on the opposing party's the rising wood of upper footboard 4.So form claw 4g and be for: even in the occasion that device is made slimming, also can fully guarantee the overhang of upper footboard 4, carry out commodity reliably and keep.

The effect of making a concession hole 4h is, when the commodity carrying out device 1 with same member makes up when being provided with, the upper footboard 4 of this relative commodity carrying out device 1 makes the leading section of brake(-holder) block 4b make a concession when closure state, does not increase the thickness of device integral body when being provided with.In addition, the effect of lug boss 4k is, when upper footboard 4 is in the maximum opening state and a part of butt of bearing components 12,13 and limit slewing area.Stop hole 4m is used for card only to be turned round an end of volute spring 8.

Below following pedal 5 is explained.Opening state, following pedal 5 be used for supporting the commodity path 10 from several the 1st commodity G (with reference to Fig. 7) down, as shown in Figure 5, the back side of its sheet metal has the bearing seat 11 of resin (such as polyacetal) system.This time pedal 5 be subjected to being contained on the pin 7 turned round volute spring 9 towards the application of force of opening direction (to the side-prominent direction of commodity path 10 shown in Figure 7).In addition, Fig. 1 and Fig. 2 represent the state that upper footboard 4 closures, following pedal 5 are opened.

Pin-and-hole 5a, the 11a of following pedal 5 is used for connecting inserting and sells 7.Card claw stop 5b is used for only bearing seat 11 of card.Special-shaped groove 14 effect that is located on the bearing seat 11 is: slided in pin 25 ends of rolling brake spare 20 described later, link for make down pedal 5 and rolling brake spare 20 by this pin 25, the actuating range of pin 25 is limited.That is, this abnormity groove 14 comprises the path slot part 14a of definite pin 25 latched positions and the big footpath slot part 14b of definite pin 25 latched positions actuating range in addition.

The effect that is located at a pair of guide hump portion 15 on the bearing seat 11 is, clamps the both sides of link component 19, and (in the lump with reference to Fig. 1, Fig. 2) do not lead on deviation in driction ground to the left and right to make the action of above-below direction of link component 19.In addition,, both can be located on the considerable part (part of the axial region side of upper footboard 4) of upper footboard 4, or also can be located on both of bearing seat 11 and upper footboard 4 though only on bearing seat 11, be provided with guide hump portion 15 here.

In addition, in Fig. 7, commodity export channel plate 100 and commodity carrying out device 1 relative configuration are to form the channel width that can hold large diameter commodity G.The lug boss 101 of commodity export channel plate 100 is for the path commodity (not shown) of bottled commodity of what is called being placed with drink agent etc. are pushed upper footboard 4 sides of commodity carrying out device 1 to, the posture that is controlled to easy these commodity of maintenance is provided with.

Below rolling brake spare 20 is explained.As Fig. 1, Fig. 2, shown in Figure 6,20 effects of rolling brake spare are: will descend pedal 5 lockings so that following pedal 5 is accepted the load of commodity with maximum opening, and when merchandise sales, remove this locking, power when making down pedal 5 back in the peristome 3 by utilizing by the commodity load also slides link component 19 by pin 24 upward, and when solenoid 17 spurs link components 19 and opens upper footboard 4 its driving force is replenished.

This rolling brake spare 20 is shown in Fig. 7 etc., with bearing seat 11 pedal 5 under maximum opening can support to approximate horizontal.This be because, from the following position of the short transverse of several the 2nd commodity G, because of the diameter of the commodity G that piles up variant, so, also will make this difference as far as possible little, to keep by upper footboard 4 reliably even during the commodity G of sale different-diameter.

This rolling brake spare 20, make its bottom rotate ground axle suspension freely by pin 23 by substrate 2 and bearing components 12,13, and be subjected to being contained on this pin 23 turned round volute spring 40 towards the application of force of opening direction (to the side-prominent direction of commodity path 10).In addition, be provided with the pin 25 that following pedal 5 is locked in maximum opening in the upper end of rolling brake spare 20.

These pin both ends of 25 are configured in down in the special-shaped groove 14 of bearing seat 11 of pedal 5, and pedal 5 is when maximum opening is locked instantly, and pin 25 is positioned at the path slot part 14a of special-shaped groove 14, are located in the big footpath slot part 14b of special-shaped groove 14 in addition the time at it.

As shown in Figure 6, pin-and-hole 20a, the 20b of rolling brake spare 20 are used for connecting inserting and sell 23,25.Lock slots 20c is provided with for the rotation that makes pin 24 engagings, locking braking brake component 20.Lock slots 20c, owing to form with the shape that is moved upward by pin 24, liberate from fastening state easily, so can remove the lock-out state of pedal 5 down with small driving force, the burden of solenoid 17 diminishes.In addition, the lock-out state of following pedal 5, promptly when pin 24 engages with lock slots 20c, pin 25 engage with path slot part 14a.

In addition, the inclined slide 20d of rolling brake spare 20 is in order to make pin 24 slips and to form when rolling brake spare 20 rotates.That is, when merchandising, attract link components 19, break away from lock slots 20c, then descend the locking of pedal 5 to be disengaged, pedal 5 quilts are pushed back in the peristome 3 by the commodity load in case sell 24 by solenoid 17.At this moment, rolling brake spare 20 is that center of rotation is pushed and gets back in the peristome 3 with pin 23 also, so pin 24 slides upward along inclined slide 20d, link component 19 is moved upward.

So, rolling brake spare 20, utilize by the commodity load make down pedal 5 back into peristome 3 when interior power and by pin 24 link component 19 is slided upward, solenoid 17 can attract link component 19 and give auxiliary force when opening upper footboard 4.

In addition, each above-mentioned member, when commodity carrying out device 1 combination with same structure is provided with, set formation not with the other side's component interference.

According to Fig. 7～Figure 12 action is described below.At sale holding state shown in Figure 7, when to solenoid 17 energisings, solenoid 17 attracts link component 19 by plunger 18.Like this, as shown in Figure 8, the pin 24 of link component 19 front ends breaks away from from the lock slots 20c of rolling brake spare 20.In a single day this locking is freed, the pin 25 of rolling brake spare 20 upper ends also breaks away from from the path slot part 14a of special-shaped groove 14, and the locking of the state of opening of following pedal 5 is disengaged, and following pedal 5 can freely turn to the rotational angle of regulation.

And, shown in the order of Fig. 9～Figure 11, when pedal 5 back in the peristome 3 because of commodity G weight instantly, then rolling brake spare 20 is that center of rotation is pushed and gets back in the peristome 3 with pin 23 also, so pin 24 slides on inclined slide 20d upward, and make link component 19 towards above move in, pin 25 inner faces along big footpath slot part 14b move.

At this moment,, upper footboard 4 is opened, so but auxiliary solenoid 17 attracts the power of link component 19 because the pin 22 that engages with the sliding tray 4d of upper footboard 4 also is brought to.Thus, even in the occasion that is difficult to open at commodity and upper footboard 4 butts,,, can keep commodity G reliably so upper footboard 4 is opened owing to can give rotating force to the direction that upper footboard 4 is opened.

So, the power when rolling brake spare 20 utilizes and makes down pedal 5 back in the peristome 3 by the commodity load, and can link component 19 be slided upward by pin 24 is given solenoid 17 attraction link components 19 and auxiliary force when opening upper footboard 4.Therefore, even solenoid 17 is maximized, also can fully drive upper footboard 4.

And, figure Figure 11, shown in Figure 12, when commodity G fall down, when commodity weight does not act on down pedal 5, following pedal 5 is the state of returning back to out by the elastic force of being turned round volute spring 9.And when the energising cut off solenoid 17, link component 19 is left behind by the elastic force of spring 30, removes the locking of 22 pairs of upper footboards 4 of pin, elastic force closed the turn back to sale holding state (with reference to Fig. 7) of upper footboard 4 because of being turned round volute spring 8.

At this moment, be positioned at the pin 22 of upper footboard 4 braking surface 4e, the back is caught by sliding tray 4d though conflict with guide plate 4c, owing to be formed with the interval of regulation from braking surface 4e to guide plate 4c, pin 22 is just to conflict with guide plate 4c greater than the impulsive force of the occasion that is not formed with this interval.

Because this impulsive force is to the directive effect with upper footboard 4 closures, so by utilizing this impulsive force, and can combine with the elastic force of being turned round volute spring 8 and rapider and reliably with upper footboard 4 closures.Especially, be absorbed in the occasion of upper footboard 4 because of variable load etc. at commodity, upper footboard 4 becomes the obstacle that returns the holding state action, but owing to make the return action of upper footboard 4 have impulse force by giving above-mentioned impulsive force, so be absorbed in disengagement from above-mentioned, turn back to holding state reliably, and can improve the reliability of device.

As mentioned above, adopt the commodity sending device for automatic vending device of present embodiment, solenoid 17 is maximized, and can fully guarantee the driving force of upper footboard 4, but the slimming of implement device and sell the commodity of various diameters.
