Description of the Related Art In a serpentine vending machine that sells products such as canned beverages, and a direct stacking type vending machine that sells products such as paper-packed beverages, the vending machine faces the lower end of the storage transport path. A switch for adjusting the width of the product passage with the lower end of the storage transport path interposed therebetween, while providing a product discharge unit for discharging the lowermost product while restricting the downward movement of the second product from below. A type or a retrofit type passage width regulating means is provided. Then, the setting position of the passage width regulating means is manually changed so as to have an appropriate product passage width according to the size of the product.

However, according to the commodity dispensing device having such a structure, when refilling the commodities, the staff must manually switch the position of the passage width regulating means.
It took a lot of trouble and time. In addition, since the location of the passage width regulating means in the storage transport path arranged on the back side is in a place that is difficult to see by the staff, the switching work must be performed by groping, and the position of the passage width regulating means is changed. There was a risk of incorrect setting.

In order to cope with this problem, the applicant of the present invention has proposed a vending machine product dispensing apparatus which does not require changing the set position of the passage width regulating means, as disclosed in Japanese Patent Application No. 2000-26636.
No. 7 proposes.

3. The positioning and drive control of the auxiliary drive belt 64 can be performed well, and the normal payout operation can be performed without any trouble.

Further, in this commodity dispensing apparatus, a high-speed dispensing operation for extracting all the stored commodities 3 at a time is performed as follows. In step S51 shown in FIG. 21, when the high-speed payout is instructed, as shown in FIG.
2 is rotated in the direction of the arrow, and the drive belt 63 and the auxiliary drive belt 64 are fed in the directions of the arrows k and m.
12, the drive sprocket 62 is continuously rotated in the reverse direction, and as shown in FIG. 12, the drive belt 63 is moved from the position close to the upper end to the upper end position further upward (the switch 81 and the switch 81 for detecting the allowable entry position). This state is detected by the high-speed payout position detecting switch 83), and the stopper 5 is raised to the high-speed payout position (steps S52 to S57). Then, at the same time, the lower end of the auxiliary drive belt 64 comes into contact with the unlocking member 65, and the unlocking member 65 resists the urging force of the compression spring 66.
Is pushed down. As a result, the lock pin 39 is pushed and rotated by the wedge-shaped portion 65a of the lock release member 65, and the lock of the receiving member 6 held in a stretched state via the lower link 40 is released, and the lock is possible. State. Thereafter, when the high-speed payout position detection switch 83 detects that the drive belt 63 has reached the upper end position, the drive motor 6 for driving the drive sprocket 62 is driven.
1 is stopped (step S58).

As a result, as shown in FIG.
, The receiving member 6 rotates in the direction of arrow j, and the payout of the product 3 starts. In this case, since the stopper 5 is in the state of being lifted, the group of products 3 following the product 3 does not obstruct the drop, and is successively paid out. In order to reliably pay out the first product 3, the unlocked state of the receiving member 6 is maintained for a predetermined time (steps S59 and S60 shown in FIG. 22).

When the continuous dispensing operation of the commodity 3 is started in this way, as shown in FIG. 14, the driving sprocket 62 is normally rotated by the driving motor 61 in the direction of the arrow, and the driving belt 63 and the auxiliary driving belt 64 are moved in the direction of the arrow. Send in g and h directions. Then, when the stopper 5 detects that the stopper 5 has moved to the normal dispensing top dead center (position close to the upper end) shown in FIG.
1 (drive sprocket 62) is stopped (step S
61 to S67). At this time, since the lower end of the auxiliary drive belt 64 moves upward, the unlocking member 65 rotates upward and returns to the original position by the urging force of the compression spring 66, but the product 3 drops continuously. Since the receiving member 6 does not rotate and return completely during the continuous payout, the lock pin 39 is fitted into the guide hole 67a at the position where the inclined surface 67b is provided. The lock does not occur.

When all the stored products 3 are dropped and paid out, as shown in FIG.
5 returns to rotate in the direction of the arrow due to the urging force of the first urging spring 16 provided on the outer surface. At this time, since the lock pin 39 can be moved to the upper side of the guide hole 67a, the receiving member 6 assumes a slightly upward posture, and this state is detected by the operation detecting switch 68 (steps S68 to S shown in FIG. 23).
71). At this time, the posture of the receiving member 6 is detected again by the operation detection switch 68, and even if the fall of the commodity 3 above is delayed for some reason, the commodity 3 is surely paid out.

Thereafter, as shown in FIG. 16, the driving sprocket 62 is again rotated forward in the direction of the arrow, and the driving belt 63 and the auxiliary driving belt 64 are fed in the directions of the arrows g and h. At this time, the stopper 5 follows the movement of the drive belt 63 by its own weight, descends to the bottom dead center, and stops. Then, when the home position detecting switch 84 detects that the drive belt 63 has been lowered to the home position shown in FIG. 16, the drive motor 61 for driving the drive sprocket 62 is stopped to oscillate the sold-out signal. And display a sold-out state to put the apparatus in a stand-by state (step S7).
2 to S77).

As described above, the provision of the home position detection switch 84 for detecting the positions of the drive belt 63 and the auxiliary drive belt 64, the entry allowable position detection switch 81, and the high-speed payout position detection switch 83 allows the stopper 5 The positioning and drive control of the receiving member 6, the drive motor 61, the drive belt 63, and the auxiliary drive belt 64 can be performed well, and the high-speed payout operation can be performed without any trouble.

According to this embodiment, the drive belt 63
By detecting the upper end position, the upper end position, the home position, and the unlock position of the auxiliary drive belt 64, the normal payout operation and the high-speed payout operation can be performed satisfactorily. The position of the drive belt 63 and the auxiliary drive belt 6
Since there is a predetermined positional relationship corresponding to the position with the position 4, a convex portion and a position detection sensor for detecting these are provided.
It goes without saying that either of the drive belt 63 and the auxiliary drive belt 64 may be provided. Further, a concave portion may be provided in the drive belt 63 or the auxiliary drive belt 64 to detect the position.

However, according to the above-described embodiment, since four position detection sensors are required, the manufacturing cost is increased by that amount, and more mounting space is required, making it difficult to provide such a space.

To cope with this, FIG. 24 and FIG.
In the vending machine commodity payout apparatus shown in FIG. 5, a home position detection switch 91 for detecting a home position and one other position detection switch 92 for detecting another point are provided. For example, a home position detecting recess for detecting that the driving belt 63 and the auxiliary driving belt 64 are located at a predetermined home position that does not come into contact with any of the stopper 5 and the unlocking member 65 on one side surface of the driving belt 63. 63f is formed. On one side surface of the auxiliary drive belt 64, the upper end of the auxiliary drive belt 64 where the drive belt 63 lifts the stopper 5 to allow the product 3 to enter the payout path 4 while the auxiliary drive belt 64 does not contact the unlocking member 65. Position, an unlocking position detecting concave portion 64g for detecting that the drive belt 63 is in the unlocked position where the unlocking member 65 is pressed down, and a drive belt 63. Is located at the upper end position where the stopper 5 is lifted to allow the product 3 to enter the payout passage 4 and the auxiliary drive belt 64 is at the unlocked position where the unlocking member 65 is pushed down. A recess 64h is formed.

According to the above configuration, as shown in FIG.
Only when the drive belt 63 and the auxiliary drive belt 64 are at the home position, only the detection terminal of the home position detection switch 91 is in a protruding state, and other position detection is performed in any of the upper end position, the unlock position and the upper position. Only the detection terminal of the home position detection switch 92 is in the protruding state, and in other places, both the home position detection switch 91 and the detection terminal of the other position detection switch 92 are in the retracted state. Therefore, the position at the home position is stored as a reference position, and thereafter, the rotation direction of the drive motor 61 based on the polarity of the load power supply to the drive motor 61 and the home position detection switch 91 are retracted from the projected state to the retracted state. By counting the number of times that the other position detection switch 92 is in the protruding state after switching to
It is possible to determine the unlock position or the high-speed payout position.

According to this configuration, since only two position detecting means are required: the home position detecting switch 91 and the other position detecting switch 92, the manufacturing cost can be reduced by that much and the mounting space can be reduced. Since only a small space is required, it is easy to install the position detecting switches 91 and 92.

The mounting positions of the position detecting switches 91 and 92 are, as shown in FIG.
What is necessary is just to attach to the attachment part 76 for attaching, etc., but it is not limited to this. Alternatively, the driving belt 63 or the auxiliary driving belt 64 may be provided with a convex portion to detect the position.

However, when the power is turned off during the operation for some reason, when the power is turned on again, the rotation direction immediately before the power failure and the home position detection switch 91 are set so as to operate normally. It is necessary to store the number of protruding states of the other position detection switch 92 after the switching, and it is necessary to provide, for example, a RAM that backs up the above information using a battery.

Still, for example, when a trouble such as a product clogging occurs in the product dispensing device, the power is turned off, and while the power is turned off, a person uses a hand or a tool to drive the driving belt 63 and the auxiliary driving belt. When the recovery work is performed by moving the product 64, or when the product dispensing apparatus in which the abnormality has occurred is replaced for each unit with a normally stopped product stopped at the home position, the information is stored in the RAM or the like. In some cases, data may become a failure and a normal operation cannot be performed. For example, when the stopper 5 is raised too much, the operation pattern at the time of high-speed operation is given despite a normal payout, and a large number of consecutive payouts are performed, or when the stopper 5 is excessively raised in the next product feeding operation, There is a risk that not only the product 3 at the lower end but also the second product 3 from the bottom will fit in the bent and inclined passage 2 to cause product clogging or to pay out two at a time.

The home position detection switch 9
When a micro switch or the like that opens and closes a contact is used as the 1 or other position detection switch 92, the home position (the state where the device is stopped for the longest Therefore, when the contact is open, an oxide film or the like may be formed on the contact. Therefore, the contact is preferably closed. However, in the case of the above-described configuration, the state of the switch at the home position is such that the home position detection switch 91 is in the protruding state, and the other position detection switch 92 is in the retracted state, so that all of these states are in the on state. To do so, it is necessary to use a normally closed type as the home position detection switch 91 and a normally open type as the other position detection switch 92. As described above, when different types of switches are used, the types of components increase, which is not preferable from the viewpoint of standardization of the components used and cost reduction.

As a solution to these problems,
Further, there is a vending machine product dispensing device provided with a position detecting means as shown in FIG. In this product dispensing device, a concave portion 63g for detecting a range of the entry allowable position-position immediately before high-speed dispensing and a concave portion 63h for detecting the home position are provided on one side surface of the drive belt 63. Here, the concave portion 63g for detecting the range of the entry allowable position-position immediately before high-speed dispensing allows the auxiliary driving belt 64 to lift the stopper 5 by the driving belt 63 to allow the product 3 to enter the dispensing passage 4, and the unlocking member 65 The drive belt 63 lifts the stopper 5 from the approach allowable position where the product 3
This is to detect that the auxiliary drive belt 64 is within the range up to the position immediately before the position where the high-speed payout is performed by pushing down the unlocking member 65 while allowing the entry into the payout passage 4. Also, the recess 63 for detecting the home position.
h is for detecting that the drive belt 63 and the auxiliary drive belt 64 are located at predetermined home positions where they do not come into contact with any of the stopper 5 and the unlocking member 65.

Further, a concave portion 64j for detecting a home position-immediately before unlocking is provided on one side surface of the auxiliary drive belt 64. The home position-immediately before lock release position detecting concave portion 64j is configured such that the drive belt 63 is unlocked from a predetermined home position position where the drive belt 63 and the auxiliary drive belt 64 do not abut on either the stopper 5 or the lock release member 65. This is for detecting that the member 65 is within a range up to a position immediately before the unlock position where the member 65 is pressed down.

Then, one first position detection switch 93 in which the contact terminal is brought into contact with one side surface of the drive belt 63
And one second position detection switch 94 in which a contact terminal is brought into contact with one side surface of the auxiliary drive belt 64. The range and the home position are detected, and the second position detection switch 94 detects the home position-the position immediately before the lock is released. The first and second position detection switches 93 and 94 are normally closed type contact opening / closing switches.

According to the above configuration, as shown in FIG.
Only when the drive belt 63 and the auxiliary drive belt 64 are at the home position, both the position detection switches 93 and 94 are in the projected state (on state), so that the home position can be easily detected. In addition, when the drive motor 61 is rotated forward to perform normal payout from the standby state, only the second position detection switch 94 is in the protruding state (on state) until the lock release position is reached, and thereafter, the lock is locked. Since the second position detection switch 94 returns to the retracted state (off state) when the unlock position is reached, the unlocked position can be detected. In addition, in the state where the vehicle is at the entry allowable position (the state where the high-speed payout position is not reached), only the first position detection switch 93 is in the protruding state (on state), and this state can be determined. When the payout position is reached, the first position detection switch 93 returns to the retracted state (off state), so that the high-speed payout position can be detected.

According to this configuration, since only two position detection switches 93 and 94 are required, the manufacturing cost can be reduced by that much, and the mounting space can be reduced. The switches 93 and 94 are also easily installed.

Further, according to the above configuration, it is possible to easily distinguish the home position, the entry allowable position, and the high-speed payout position or the unlock position. Even when the power is turned on, it can be returned to the normal state.

Here, the return operation is performed as follows. For example, when the vehicle stops at the high-speed payout position shown in FIG. 26A and the power is turned on again, the control is at the abnormal stop position based on the off signals from the position detection switches 93 and 94. Is determined, and a return operation to the home position is immediately performed. That is, the drive motor 6
After the first motor 1 is rotated forward and moved to the home position after passing through the approach allowable position, the drive motor 61 is stopped.

When the power is stopped at the positions shown in FIGS. 26B and 26C and the power is turned on again, the on signal from the position detection switch 93 and the position detection switch 94 are output.
In the control, it is determined from the off signal from the controller that the vehicle is located within the allowable range of entry-position immediately before high-speed payout, and in this case, the operation of returning to the home position is immediately performed. That is, after the drive motor 61 is rotated forward and moved to the home position, the drive motor 61 is stopped.

In FIG. 26, when the motor is stopped at the position shown in FIG. 26D and the power is turned on again, it is determined from the off signals from the position detection switches 93 and 94 that the vehicle is at the abnormal stop position in control. The determination is made, and the operation of returning to the home position is immediately performed. That is, after the drive motor 61 is rotated forward and moved to the home position, the drive motor 61 is stopped.

In FIG. 26, when the motor is stopped at the home position shown in FIG. 26E and the power is turned on again, from the on signals from the two position detecting switches 93 and 94, the home position is controlled. It is determined that there is. In this case, if it is detected based on the signal from the receiving operation detecting switch 68 that the product 3 has not been received, after the selling-out release operation is performed, the selling standby process or the selling-out sending process is performed. Is performed, and if it is detected that the product 3 has been received, it is set to the sales standby state and the processing ends normally.

In FIG. 26, when the operation is stopped at the position shown in FIG. 26F and the power is turned on again, the control signal is obtained from the off signal from the position detection switch 93 and the on signal from the position detection switch 94. Is determined to be in the range between the home position and the unlocked position (a range between the home position and the unlocked position and not including the home position and the unlocked position). In this case, when it is detected that the product 3 has not been received based on the signal from the receiving operation detection switch 68, it is determined that the product has been paid out, and the drive motor 61 is rotated in the reverse direction. After moving to the home position, the drive motor 61 is stopped. On the other hand, when it is detected that the product 3 has been received based on the signal from the receiving operation detection switch 68, the product is being moved from the home position to the unlock position, and the product payout operation is being performed. It is determined that the product has not been paid out yet, the drive motor 61 is rotated forward and moved to the unlock position and stopped for a predetermined time, and after the product is paid out, the drive motor 61 is rotated in the reverse direction. Move to the home position and stop the drive motor 61.

In FIG. 26, when the motor is stopped at the position shown in FIG. 26G and the power is turned on again, it is determined from the off signals from the two position detecting switches 93 and 94 that the vehicle is at the abnormal stop position in control. The determination is made, and the operation of returning to the home position is immediately performed. First, the drive motor 61 is rotated forward. However, in this case, the drive motor 61 cannot rotate and the motor is locked.
The return to the home position cannot be detected within the predetermined time (time exceeding the time required to return from the high-speed payout position to the home position). Therefore, after confirming that there is no return signal to the home position, the drive motor 61 is reversed to move to the home position, and the drive motor 61 is stopped.

As described above, according to the above configuration, even if the position information is not stored, the power supply may be cut off during the operation, or the person may perform the moving operation of the drive belt 63 or the auxiliary drive belt 64, etc. After that, even if the power is turned on again, it is possible to satisfactorily return to the normal state without causing multiple dispensing of products or clogging of products, and it is not necessary to store position information, The cost of electric parts can be reduced, and the structure of the control software can be simplified.

In the home position, since both of the position detection switches 93 and 94 are in the protruding state, as described above, both of the position detection switches 93 and 94 are in the protruding state.
By using a normally closed contact opening / closing switch, not only environmental weather resistance is improved, but also the position detection switch can be used in common, so from the viewpoint of standardization of parts used and cost reduction. Is also preferred.

In this embodiment, the drive belt 63 and the auxiliary drive belt 64 may be provided with a convex portion having a similar shape to detect the position. In this case, a normally open type of position detection means is used. A similar effect can be obtained by using a contact opening / closing switch.
