Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a non-electrically operated manually operated lock device for a vending machine. This invention relates to a locking device for a vending machine, in which an opening/closing part is unlocked by pulling the box forward by hand, and the items for sale in the item storage box can be taken out.

(Prior Art and its Problems) As a conventional lock device for a vending machine of this type, 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. The actuating body is provided with a stopper that engages with the lower part of the detector, and moves to come 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 this 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,
2 pieces of DIME (equivalent to 10 cents) and 1 piece of NICKEL (equivalent to 5 cents), or 1 piece of DIME and NICKEL
It was very inconvenient that three different types of coins could not be used together.

(Technical Means for Solving the Problems) The first purpose of the present invention is to provide a lock device for a vending machine that can use different types of coins, in view of the above-mentioned conventional problems. There is.
A second important objective of the present invention is to prevent malfunctions by suppressing misalignment of coins in the coin passage when coins with small diameters are used. Therefore, the technical means for achieving these objectives is that one end is pivotally attached to the opening/closing door 2 side of the sales item storage box 1 with elasticity biased upward, and the other end is pivoted to the opening/closing door 2 side of the sales item storage box 1. A locking member 3 formed with a chevron-shaped cam 87 and a locking member 3 inserted into a locking member insertion opening 7 provided at a required portion of the front surface of the coin box 4.
a locking member 25 that engages with the locking member to lock the locking member so that it cannot be removed; a coin slot 5 provided in the upper front part of the coin box 4 so that a plurality of types of coins can be inserted therein; and a ramp. The coins inserted through the coin slot 5 are arranged so that they can be stacked vertically in an upright position, and the exit end faces the top surface of the locking member. A coin passageway 31 in which coins of 100 and 100 are made to protrude from the exit end of the coin passageway and come into contact with the locking member 3, and several types of coins with different array lengths each having a predetermined sales amount. A plurality of stoppers are arranged corresponding to the coin arrays of the combinations, 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 only when a coin passes through. A plurality of stoppers 68 which are adapted to be withdrawn and which are adapted to hold the lowest coin in a state protruding from the exit end of the coin passage 31 by the above-mentioned plunge, and a guide piece 45a are arranged along the longitudinal direction of the coin passage 31. The guide piece 45a protrudes into the coin passage along the direction and guides and guides the small diameter coin along the lower surface side of the ramp serving as the coin passage 31 when a small diameter coin is inserted, and when a large diameter coin is inserted. a guide member 45 configured to exit the coin passage 31 by contact with the large-diameter coin in order to widen the width of the passage pinched by the entry of the coin, By pulling the locking member 3 to open the opening/closing door 2 when a combination of coins is inserted,
The locking member 3 is configured to be displaced downward and separated from the locking member 25 as the chevron-shaped cam 87 slides into contact with the lowest coin.

(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 locking the locking member 3. is released, and it becomes possible to take out the sales item from the sales item storage box 1. 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,
Since the stopper 68 does not protrude into the upper end position of the highest coin in the coin array and can move upward (toward the entrance side), even if the opening/closing door 2 is pulled, the locking member 3 is not inserted into the top end of the coin. Side chevron cam 8
7 has pushed the lowest coin up and cannot displace itself and therefore the lock cannot be released.

Further, when coins with a small diameter pass through the coin passage 31, these coins are moved by the guide member 4.
The coins are guided along the lower surface side of the ramp serving as the coin passage by the guide piece 45a of No. 5, and are arranged in the coin passage in an aligned state. By contacting this guide piece 45,
The passage width, which had been narrowed by a, is now expanded.

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 85 comes into contact with the sloped end of the locking member 25 and moves along this as shown in FIG. When the locking member 25 is rotated downward as shown by the two-dot chain line in A and further advanced in this state, the tip of the locking member 25 fits into the engagement hole 84 as shown in FIGS. 16A and B, and the rotating piece 3c is pulled out. 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 different coins N5 pieces, and assuming that the coin combination S corresponding to the 50 cent Sunday edition does not use coin N, S ₁ = coin Q2 pieces S ₂ = coin Q1 piece + 3 coins D (no change) S ₃ = 4 coins D, and the array length of each combination W ₁ to W ₅ and S ₁ to S ₃ is the maximum because the diameters of coins N, D, and Q are different. The upper end of the upper 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, in the same way as in the case of the weekday edition described above, in the case of the Sunday edition, the lock is released by inserting coins in the combinations _S1 to _S3 , and the opening/closing door 2 can be opened as the arrayed coins fall.

In the locking device described above, each stopper 6
As shown in FIG. 18, when the coins N, D, and Q come into contact with each other from above, the long leg piece 69a of 8 rotates downward as shown by the two-dot chain line and withdraws from the inside of the coin passage 31, thereby obstructing the passage of the coin. do not. In addition, if the guide member 45 is not present, there is a risk that the arrangement of small and medium-sized coins D and N may be disrupted in the coin arrangement section 31b as shown in FIG. 19A.
Since the guide piece 45a of the guide member 45 enters into the coin passage 31 and the passage width of the arrangement portion 31b becomes narrower as shown in FIG. suppressed. Moreover, since the upper part of the guide piece 45a is inclined as shown in FIG.
Similarly, it rotates from the coin passage 31 and is drawn in as shown by the two-dot chain line, so that it does not obstruct passage. Furthermore, guide piece 4
Since the lower end of 5a is formed only to a position higher than the large-diameter coin Q located at the lowest position, it returns and operates again after the large-diameter coin Q passes.

Note that 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 Sunday edition 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 does not press the coin sorting member 59. Sorting section 31a
The large-diameter coin Q is larger in diameter than the vertical width of the removal port 39, so it passes while rotating the leg piece 59a, and the small-diameter coin D passes under the leg piece 59a. But,
The medium diameter coin N comes into contact with the leg piece 59a and enters the removal port 39.
The coins are ejected into the hollow part 35 and returned to the pocket part 15 of the coin return slot 10 through the opening 35a. Furthermore, due to the length of the coin array, the stopper is 68.
e is N4 coins (20 cents) in the weekday edition position, and the stopper 68g is a coin in the Sunday edition position.
Although there is a possibility that the stopper control members 82a and 82b may be activated with two pieces of D (20 cents), 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. and make it 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 28 rotates to the left in the figure around the round shaft-shaped projection 50 against the tensile force of the springs 30a, 30b, and 30c. Along with this, coin passage 31
is expanded, the inserted coin is ejected from the exit opening 33 which is moved to the upper side of the ramp 16 and expanded, and the coin can be taken out from the return opening 10.

In the above embodiment, the coin box 4 is provided independently outside the sales item storage box 1, but in the present invention, the coin box 4 is integrated into the sales item storage box 1. is also possible. Furthermore, the types of coins used, the set prices, the types of items for sale, etc. can be changed in various ways. 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. These may be configured to be operated with the biasing force appropriately adjusted via a spring member.

(Effects of the invention) The locking device for a vending machine of the invention allows a predetermined amount of coins to be inserted depending on the array length of the coins, which 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 a plurality of types of coins for one sales amount, and of course it is also possible to use a plurality of coins of the same type as well as a single coin.

Further, according to the present invention, the guide member 45 is provided in the coin passage 31, so that when a coin with a small diameter is inserted into the coin passage 31, it is guided along the lower surface side of the coin passage. Therefore, disturbances in the arrangement of small diameter coins in the coin passage are suppressed and a good arrangement is achieved, thereby preventing malfunction of the locking device.
