Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a lock device for a vending machine, and in particular to a lock device for a vending machine. This invention relates to a manually operated locking device for a vending machine, in which an opening/closing part is unlocked so that items for sale in an item storage box can be taken out.

(Prior Art and its Problems) As a conventional lock device of this type for a vending machine, there is one described in Japanese Utility Model Publication No. 18790/1983. This device is equipped with a detector that communicates with the coin slot inside the main body, which has a coin slot on the top.At the bottom of this detector, there is an actuating body that is rotatably attached to one end of a bell crank and faces upward. The actuating body is provided with a stopper that engages with the lower part of the detector, and moves into contact with the coin at the lower part of the detector.
An angle-shaped cam is formed to disengage the stopper, and the lower end of a vertical lever connected to the other end of the bell crank is rotatably connected to the rear lower part of the opening/closing part, and the lever is moved downward. Then, insert a coin from the slot, pull out the opening/closing part, and raise the bottom rear part of the opening/closing part to raise the lever and rotate the bell crank. The rotation of the actuating body in conjunction with the rotation of the bell crank causes the chevron-shaped cam to slide along the lower edge of the coin dropped at the bottom of the detector, and the stopper of the actuating body is moved to the bottom of the detector. It was designed to separate from the

However, in a device with such a configuration,
Since the coins that can be used are limited to the same type of coins, it is recommended to use a type that is dedicated to a certain type of coin, or a combination type that has multiple locking devices with separate coin slots for each type of coin. Therefore, taking the US currency as an example,
For example, if the price of the item for sale is 25 cents,
It was very inconvenient because it was not possible to use different types of coins together, such as two DIME coins (equivalent to 10 cents) and one NICKEL coin (equivalent to 5 cents), or one DIME coin and three NICKEL coins.

(Technical Means for Solving the Problems) In view of the above-mentioned problems, the present invention aims to provide a lock device for a vending machine that can use different types of coins. The technical means for achieving this is a locking mechanism whose one end is pivotally attached to the opening/closing door 2 side of the product storage box 1 with an upward elastic force, and a chevron-shaped cam 87 is formed at the other end. A locking member 3, a locking member insertion slot 7 provided at a required portion of the front surface of the coin box 4, and a locking member insertion slot 7 provided inside the coin box 4 and inserted into the insertion slot 7 when the opening/closing door 2 is closed. A locking member 25 that engages with the locking member 3 and locks the locking member so that the locking member cannot be removed; and a coin slot 5 that is provided in the upper front part of the coin box 4 so that a plurality of types of coins can be inserted thereinto. , which communicates with the coin slot 5 and has an outlet end facing the locking member, arranges the coins inserted through the coin slot 5 so that they can be vertically stacked in an upright state, and arranges the coins inserted through the coin slot 5 so that they can be vertically stacked. A coin passageway 31 in which coins are made to protrude from the exit end of the coin passageway and come into contact with the locking member 3, and several combinations with different array lengths, each with a predetermined sales amount. A plurality of stoppers are arranged corresponding to the respective coin arrays, and are inserted into the coin passage 31 at a position corresponding to the upper end position of the highest coin in the various coin arrays, and exit only when a coin passes. and a plurality of stoppers 68, which are adapted to hold the lowest coin in a state protruding from the exit end of the coin passage 31 when the coin enters the coin passage 31, and a predetermined sales amount is reached. By pulling the locking member 3 to open the opening/closing door 2 when coins of various combinations are inserted, the locking member 3 is displaced due to the sliding contact between the chevron cam 87 and the lowest coin. The lock member 25 is configured such that it can be detached from the lock member 25.

(Operation) When a certain combination of coins is inserted through the coin slot 5, the coins are arranged in a vertical stack in the coin passage 31. In this coin passage 31, the lowest coin in the coin arrangement protrudes from the exit end of the coin passage 31 and comes into contact with the upper surface of the locking member 3, and the stopper 68 enters the upper end position of the highest coin. Therefore, the movement of this combination coin back to the entrance side of the coin passage 31 is prevented. By pulling the opening/closing door 2 in this state, the locking member 3 is displaced downward due to sliding contact between the chevron cam 87 and the lowest coin, and is disengaged from the locking member 25, thereby releasing the lock. This release allows the product to be removed from the product storage box 1.

In addition, if a coin with an amount that does not reach the predetermined sales amount or a coin of a type other than the preset combination is inserted into the coin passage 31, a stopper 68 is placed at the upper end position of the highest coin in the coin array. Since it is in a state where it can move upward (toward the entrance side) without being in the plunged position, even if the opening/closing door 2 is pulled, the locking member 3 will not move into the chevron cam 87 on the tip side.
The lowest coin is pushed up by the coin and cannot be displaced by itself, so the lock is not released.

(Example) The present invention will be described below based on an example in which the present invention is applied to a newspaper vending machine that can be used to sell both low-priced weekday editions and high-priced Sunday editions.

This is to prevent the opposing positions of 0 and 70 from shifting.

In assembling the coin detector 24 shown in FIGS. 7A to 7D, the outer frame 29 is assembled as shown in FIG.
By fitting the fitting hole 47 of the inner frame body 28 into the protrusion 50 and rotating the inner frame body 28, the inner frame body 28 is fitted to the inner surface side of the outer frame body 29, and the outer plate 27 is rotated on the vertical side thereof. The L-shaped reinforcing plate 74 is fitted onto the inner frame 28 with the rising piece 74a sandwiched between the lower part thereof. In this state, the coin passage 31 is connected to the inner frame 2.
It is formed between the partition wall 34 of No. 8 and the substrate wall 29d of the outer frame body 29. Further, the reinforcing plate 74 has a circular hole 74.
b is bored, and the circular hole 74b and the screw hole 48 of the inner frame body 28 are located concentrically, and a locking screw 75 that engages with the notch groove 18a of the tilting lever 18 is installed in this part. It's screwed on. On the other hand, the stopper support 55 has sliding guide protrusions 67a, 67b,
67c into the guide grooves 58c, 58b of the outer frame body 29,
58d, the sliding screws 7 are attached to the fitting portions 56 of the outer frame body 29 so as to be slidable up and down, and are inserted through the guide grooves 58a of the outer frame body 28.
6 is screwed into the screw hole 66a to regulate the sliding width.
A coil spring 77 is interposed between the lower end portion of the lower end portion of the lower end portion of the lower end portion of the lower end portion of the lower end portion of the coil spring. In addition, the outer frame body 29
A substantially dogleg-shaped pressing lever 78 is placed at the upper position of the inner protruding wall 54b, and its short rotation angle regulating piece 78a fits into the slot 66b of the stopper support 55, and the long pressing piece 78b is rotatably attached so that it can come into contact with the coin sorting member 59, and furthermore, a coil spring 79 is interposed between the pressing piece 78b and the horizontal wall 54d of the outer frame 29, so that the pressing piece 78b Tensile bias. On the other hand, the sliding screw 76 rotatably supports the upper part of a switching lever 80 made of a metal plate or the like having a substantially triangular shape and having an operation protrusion 80a bent at the lower end. Groove 80b
The fixing screw 81 is fixed on the lower inclined surface through the screw. Note that 82a is the pressing piece 78b of the pressing lever 78.

Figure 15 shows the handle 2a of the opening/closing door 2 shown in Figure 1.
The locking member 3 includes a mounting piece 3a screwed to the handle 2a and a rotating piece 3c pivotally supported thereon via a shaft 3b so as to be able to rotate only downward from a horizontal position. The rotating piece 3c is always kept in a horizontal position by a spring 3d, that is, when the handle 2a
It is biased upward so as to form an angle of about 90° with respect to the The rotating piece 3c has an elongated engagement hole 84 at one end thereof, and
The tip part is divided into two pieces, the tip piece 85 on the side of the engagement hole 84 is short and slopes downward, and the other tip piece 86 is long and curved in a substantially V-shape to support the chevron-shaped cam 87. is forming. When the rotating piece 3c of the locking member 3 is inserted through the locking member insertion opening 7 of the coin box 4, the shorter end piece 85 comes into contact with the sloped end of the locking member 25 and moves along the slanted end of the locking member 25. When the locking member 25 is rotated downward as shown by the two-dot chain line in FIG. It becomes impossible to pull out and the opening/closing door 2 becomes locked. In this locked state, the coin drop hole 14a of the base plate 14 is blocked by the rotating piece 3c,
Therefore, when the coin detector 24 is installed as shown in FIG. At position 33, the coin contacts the rotating piece 3c in a partially protruding form and does not fall to the inner bottom surface of the coin box 4. At this time, since the vicinity of the lower end of the coin sorting part 31b is in the vertical direction, the protruding posture is more stable even for small-diameter coins than in the case where the coin sorting part 31b is inclined.

On the other hand, the coins N, D, and Q inserted under the above-mentioned locked state are stored in the coin array section 3 of the coin passage 31.
The coins are stacked and arranged in an upright position in 1b, and the length of the arrangement varies depending on the combination of coins N, D, and Q that have been inserted. In other words, the coin combination W corresponding to the weekday version of 25 cents is: W ₁ = 1 coin Q W ₂ = 3 coins D (no change) W ₃ = 2 coins D + 1 coin N W ₄ = 1 coin D + coin N3 pieces W ₅ = 5 ways of coin N5 pieces, and assuming that the coin combination S corresponding to the 50 cent Nikyaku version does not use coin N, S ₁ = coin Q2 pieces S ₂ = coin Q1 coin + 3 coins D (no change) S ₃ = 4 coins D, and the array lengths of each combination W ₁ to W ₅ and S ₁ to S ₃ are because the diameters of coins N, D, and Q are different. The upper end of the highest coin has the length shown in FIG. However, under the condition shown in Fig. 7C, stopper 68g is at W ₁ , stopper 68c is at W ₂ , and stopper 68f is at W 1.
The tip of a long leg piece 69a that does not rotate upward is positioned protruding directly above the upper end of the top coin corresponding to W ₃ , 68b to W ₄ , and 68d to W ₅ , respectively.
For this reason, the movement of the arranged coin combinations W ₁ to _{W 5} back to the entrance side within the passage 31 is prevented. Therefore, when coins with combinations W ₁ to _{W 5} are inserted, the rotating member 3 is opened by pulling the opening/closing door 2.
c, the protrusion 87 contacts the downward protrusion of the lowest coins N, D, Q and is pushed down along this;
As the lock member 25 rotates downward as shown by the two-dot chain line in FIG.
can be opened, and at the same time, the arranged coins fall downward from the coin drop hole 14a of the base plate 14. Furthermore, when the switching lever 80 is switched from the state shown in FIG. , in this descending state, the stopper 68f is set to S ₁ ,
8c corresponds to _S2 , and 68a corresponds to _S3 , and the tip of the long leg piece 69a is positioned to protrude directly above the top end of the topmost coin. Therefore, as in the case of the above-mentioned weekday edition, in the case of the Nichiyaku edition, the lock is released by inserting coins in combinations S ₁ to _{S 3} , and the opening/closing door 2 can be opened as the arranged coins fall.

Note that the long leg piece 69a of each stopper 68 is the first
As shown in Figure 8, when coins N, D, and Q touch each other from above, they rotate downward as shown by the two-dot chain line and pass through the coin passage 3.
Since it is lower than 1, it does not obstruct the passage of coins. Further, the guide piece 45a of the guide member 45 has the function of aligning the small and medium-diameter coins D and N toward the lower inclined surface 24c within the coin array portion 31b and suppressing fluctuations in the array length due to irregularities in the array. Since it is slanted, when a large-diameter coin Q passes through, when it comes into contact with the upper part, it rotates and pulls in from within the coin passage 31 in the same way as the stopper 68, and does not obstruct the passage. On the other hand, when the switching lever 80 is in the weekday version position, the pressing piece 78b of the pressing lever 78 presses the coin sorting member 59, and the long leg piece 59a does not protrude toward the coin sorting section 31a. Since the inserted coin rolls in a state where it is about to fall toward the substrate wall 29d side of the outer frame 29 due to the inclined side wall surface 41 and the protrusion 64 of the coin sorting section 31a, any of the coins N, D, and Q Also passes through the sorting section 31a.
However, when the switching lever 80 is in the Nichiyakuban position, the pressing piece 78b rises in conjunction with the lowering of the stopper support 55 and does not press the coin sorting member 59, and the long leg piece 59a Coin sorting section 31a
The large-diameter coin Q protrudes through the coin removal port 39.
Since the diameter is larger than the vertical width of the removal port 39, the small diameter coin D passes through while rotating the leg piece 59a.
The medium-diameter coin N passes under the leg piece 59a and passes, but the medium-diameter coin N comes into contact with the leg piece 59a, is ejected from the removal port 39 into the hollow portion 35, and is returned to the pocket portion 15 of the coin return port 10 through the opening 35a. Ru. Furthermore, due to the length of the coin array, the stopper 68e
is N4 coins (20 cents) at the weekday version location, and the stopper 68g is D2 coins at the Nichiyaku version location.
Although there is a possibility that the stopper control members 82a and 82b may operate with each stopper (20 sets), the stopper control members 82a and 82b contact and rotate the stoppers 68e and 68g at each of the above positions as the holding body 55 moves up and down. Inactive.

Furthermore, when the return lever 9 is rotated when a problem such as a coin jam occurs, the entire coin detector 24 first tilts to the left in the figure around the pivot pin 23 from the state shown in FIG. , Next, the guide piece 51 is regulated by the guide frame 26, so the inner frame body 2
8 is a spring 30a, 30 centered around a round shaft-shaped protrusion 50.
The coin passage 31 is rotated to the left in the figure against the tensile force of the coin passages 30b and 30c, and the ramp 1
6 Exit opening 33 moved upward and enlarged
The inserted coin is ejected from the slot 10, and the coin can be taken out from the return slot 10.

In the above embodiment, the coin box 4 is provided so as to protrude from the outside of the sales item storage box 1, but it is also possible to have a structure in which the coin box 4 is integrated into the sales item storage box 1. . In addition, in the above embodiment, a switching mechanism and a coin sorting mechanism are provided in order to apply to two types of selling product prices, but these mechanisms are unnecessary when applying to a single selling product price. . Furthermore, the types of coins used, set prices, types of items for sale, etc. can be changed in various ways. still,
In the above embodiment, the weight, shape, pivot position, arrangement angle, etc. of the stopper 68, guide member 45, and coin sorting member 59 are set so that they are all operated by their own weight. It may be configured to operate with the biasing force appropriately adjusted via a spring member.

(Effects of the Invention) The locking device for a vending machine of the present invention allows a predetermined amount of coins to be inserted depending on the length of the array of coins that differs for each combination of coins (including the case of only one coin) for a predetermined amount. A plurality of stoppers 68 are arranged at positions corresponding to the upper end position of the highest coin in a coin arrangement of several combinations, each of which has a predetermined amount. Then, when a combination of coins corresponding to a predetermined amount is inserted, the stopper 68 inserted into the upper end position of the highest coin will move the coins of the array corresponding to the combination to the lowest coin. The locking member 3 is held in a state protruding from the exit end of the coin passage, and in this state, the locking member 3 is unlocked by pulling the locking member 3 to open the opening/closing door 2. It is possible to use multiple types of coins for one sales amount, and of course, it is also possible to use multiple coins of the same type or use one coin.
