Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a multi-tiered product storage shelf provided with a product sending-out unit, and a vertically movable product mounting product to be sent from the product storage shelf. And a lifting mechanism that drives the mounting table up and down, and a feed prevention unit that prevents the product from being sent from the product storage shelf to the mounting table at each of the sending end portions of the product storage shelf. A vending machine provided with a blocking member that is switchable between a posture and a sending permission position that allows sending of goods to the mounting table, and an urging mechanism that urges each of the blocking members to return to the sending blocking position. Related to a product carrying out structure.

[Conventional technology]

In a conventional product unloading structure of a vending machine, a blocking member in a delivery blocking position is moved in a delivery allowable position against a return biasing force of the biasing mechanism as the blocking member comes into contact with a product delivered in a product storage shelf. And a locking mechanism for preventing the blocking member in the delivery-preventing position from swinging to the delivery-permissible position is provided on each of the product storage shelves. A cam plate for pressing the unlocking operation member of the locking mechanism from the locked position to the unlocked position in accordance with the approach movement of the product storage shelf to the product delivery location has been fixed (for example, in the actual case). See JP-A-62-135990).

[Problems to be solved by the invention]

In the conventional structure as described above, when the mounting table reaches the designated product delivery location of the specified product storage shelf, the unlocking operation member of the locking mechanism is switched to the unlocking position by the cam plate of the mounting table. When the delivery means of the product storage shelf is activated in that state, the product on the product storage shelf is pushed down by the delivered product itself to the delivery allowable position against the return biasing force against the return urging force. Is transferred to the mounting table.

Therefore, if the return biasing force of the biasing mechanism is reduced so that the blocking member in the delivery blocking position can be reliably switched and rocked to the delivery permissible position even if the product is small in measurement, the delivery blocking by the blocking member is prevented. Since the mechanism is lowered, as described above, it is essential to provide a locking mechanism for preventing the blocking member in the delivery-preventing position from abuttingly swinging to the delivery-permissible posture, and in the delivery-permissible posture. Since it takes time for the blocking member to return to the delivery blocking position, not only is the possibility of causing a subsequent product to fall during that time, but also the product payout time is reduced by the delay in the start of lifting and lowering of the mounting table. There was a problem of getting longer.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to increase the urging force of the blocking member to return to the delivery-preventing posture, thereby ensuring the delivery-preventing function and reducing the return time. Even if the products stored in the product storage shelf are lightweight and small, they can be reliably and smoothly sent out to the mounting table, and at the same time, it is possible to prevent the product from falling off from the product storage shelf other than specified. It is an object of the present invention to provide a vending machine product carrying-out structure capable of simultaneously reducing noise.

[Means for solving the problem]

The characteristic configuration of the product unloading structure of the vending machine according to the present invention, in the configuration described above, in each of the product storage shelves,
In addition to providing a posture switching mechanism for switching the blocking member to a delivery allowable posture against a return biasing force of a biasing mechanism, the mounting table includes a product storage shelf that moves the product storage shelf close to a product delivery location. An operation member for switching the attitude switching mechanism of the storage shelf and an operation selecting means for switching the operation member between the operating position and the non-operating position are provided. The operation and effect of the operation member are as follows.

(Operation)

When the mounting table moves close to the specified product delivery location of the specified product storage shelf, the operation switching mechanism of the product storage shelf is switched by the operating member provided on the mounting table, and the blocking member in the delivery blocking position is urged. It is forcibly switched to the sending allowable posture against the return urging force of the mechanism. In addition, the operating member is switched to the operating position when moving closer to the product delivery location of the designated product storage shelf by the operation selecting means, and the operating member is not operated when passing through the product storage shelf other than the designated product storage shelf. By holding at the position, it is possible to prevent the blocking member provided on the product storage shelf other than the designated one from being switched to the sending allowable posture every time the mounting table passes.

〔The invention's effect〕

Therefore, since the blocking member in the delivery blocking position is forcibly switched to the delivery allowing position using the lifting force of the mounting table, the return biasing force of the blocking member to the delivery blocking position is increased, and the delivery blocking function is increased. In this way, even if the product stored in the product storage shelf is lightweight and small, the product can be reliably and smoothly sent out onto the mounting table, while ensuring the reliability and shortening the return time. In addition, since there is no need for a blocking member provided on a non-designated product storage shelf, the switching operation is not performed to the sending allowable posture, and the product caused by the switching operation of the blocking member in the non-designated product storage shelf is not operated. It was possible to suppress the falling off and to reduce the noise.

〔Example〕

Hereinafter, a vending machine according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 3 shows a vending machine that sells products (S) such as cans and bottles, and a plurality of storage shelves as a belt-conveyor-type product transport device (1) that supports the products (S). In addition, a first electric motor (2) is provided in each storage shelf (1) as a delivery means for rotating and driving the storage shelf (1) so that the product (S) is sent to the right side of the paper surface. . An endless chain (4), which is vertically mounted on one mounting table (3) for receiving and mounting the product (S) sent from one of the plurality of storage shelves (1).
And a second electric motor as an elevating mechanism (5) for rotating the endless chain (4) in the forward and reverse directions.

With the above structure, when the purchaser selects a product (S) to purchase, the mounting table (3) is moved up and down to the position of the storage shelf (1) where the selected product (S) is located. Thereafter, the stopped storage rack (1) is fed and driven by the first electric motor (2), and when one product (S) is sent to the mounting table (3), the first electric motor (2) is turned on. Stop. Then, the mounting table (3) is moved up and down to the product outlet (6), and the purchaser can take out the product (S) from the product outlet (6).

Next, the structure in which the product (S) is stopped at the end on the mounting table (3) side of each storage shelf (1) will be described in detail. The storage shelf (1) as shown in FIGS. A gate-shaped blocking member (7) is swingably supported around a horizontal axis core (P ₁ ) at the end of the shaft, and a blocking member (7) is provided by a helical spring (8) as an urging mechanism (8). 7) is urged clockwise in FIG. 1, and the drop prevention member (7) is located in the third posture (III) without any product (S).

In the state shown in FIG. 1, the product (S) sent from the right side of the drawing by the feeding action of the storage shelf (1) moves the blocking member (7) from the third position (III) to the first position. (I), and in this state, the blocking member (7)
Is separated from the first limit switch (9), and this is detected, and the storage shelf (1) stops. The blocking member (7) is stopped in the first position (I) by a hook member (10) as shown in FIG.

Next, when the mounting table (3) has moved to the position of the storage shelf (1) in which the product (S) to be purchased is located, the blocking member (7) is moved to the second position (II), which is the sending allowable position. The structure and movement of the switching attitude switching mechanism (11) will be described in detail. As shown in FIG. 1, an arm (7a) extends downward from the base of the blocking member (7) and is slidable in the horizontal direction on the paper. One end of the supported rod (12) is engaged with the elongated hole (7b) of the arm (7a), and a roller (12a) is attached to the other end of the rod (12). On the other hand, the mounting table (3) has the first and second actuators (1
The first and second cams (15) and (16) are provided with trapezoidal shapes which can be freely moved in and out according to (3) and (14).

That is, the first cam (15) constitutes an operation member for switching the attitude switching mechanism (11) of the product storage shelf (1) as the product storage shelf (1) moves closer to the product delivery location. And the first actuator (13)
Thus, an operation selecting means for switching the first cam (15), which is the operation member, between an operating position and a non-operating position is configured.

With the above structure, when the purchaser selects a product (S) to purchase, the mounting table (3) moves to the storage shelf (1) where the product (S) is located. (15) and (16) are retracted to the non-operating position,
When approaching the storage shelf (1) containing the product (S) to be purchased, the cams (15) and (16) are operated to project to the operating position as shown in FIG. When the mounting table (3) reaches the position of the target storage shelf (1) in such a state, the mounting table (3) is lowered from above as shown in FIGS. The second cam (16) moves the rod (1).
7) is pushed to remove the hook member (10) from the blocking member (7), and at the same time, the rod (12) in the posture switching mechanism (11) is pushed by the first cam (15), and the fall preventing member is pressed. (7) is tilted to the second posture (II) and operated.

Then, when the above-described state is detected by the second limit switch (17), the storage shelf (1) stores the product (S).
Is driven by a distance corresponding to one of the above. Then, the blocking member (7) in which the product (S) is in the second position (II)
Is rolled down on the mounting table (3) while further pushing down by its own weight.

Further, the goods (S) are transferred from the storage shelf (1) to the mounting table (3).
When sending out the goods, instead of driving the storage shelf (1) itself, the goods (S) are pushed by a separate pusher or discharge arm, etc.
May be transferred to the mounting table (3).
