Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a product delivery device for a vending machine.

(B) Conventional technology A semi-cylindrical delivery member whose rotation is controlled by a motor is provided at the bottom of a storage column in which cylindrical products are stacked and stored in a horizontal position. A product delivery device is conventionally known, which is configured to store and lock products and sequentially send out the lowest order products one by one by rotating a delivery member by a motor. It is disclosed in Publication No. 47-26709 and the like. That is, the lowest product among the products stacked and stored in the - column is received in the semi-cylindrical body of the delivery member, is stored and locked, and is in a standby state, and the delivery member is rotated by the rotation of the motor based on the delivery command. It rotates to send out the lowest product, and at the same time stores and locks the next product in the semi-cylindrical body and returns to the standby state again.When the feed member rotates once, the trap sends out the lowest product and the next product. It is inserted between the product and the next product, and when it is received on the outer circumferential surface of the semi-cylindrical body of the sending member, the lowest product stored and locked in the semi-cylindrical body is dropped and sent downward. .

(C) Problems to be Solved by the Invention This prior art technology is based on the problem that the lowest product is stored and locked in the semi-cylindrical body of the delivery member by rotation of the delivery member, and the product is stacked on top of the lowest product. In order to insert the delivery member between the next stage product and the next stage product, the next stage product must be pushed upward by the delivery member. In other words, since the outer diameter of the semi-cylindrical body is larger than the diameter of the product stored and locked inside the semi-cylindrical body, when entering between the lowest product and the next product, the next product is moved upward. It will push it up.

Therefore, if the product diameter is the same as the inner diameter of the semi-cylindrical body, the push-up is equal to the thickness of the semi-cylindrical body, but the product diameter is smaller than the inner diameter of the semi-cylindrical body. In this case, the next product is pushed up by the sum of the difference between the product diameter and the inner diameter of the semi-cylindrical body and the thickness of the semi-cylindrical body. For this reason, a large load is placed on the delivery member,
In addition to causing a rotational failure, the leading end of the delivery member damages the next-stage product because the product is forcibly pushed up.

The present invention provides a product dispensing device for a vending machine that can eliminate such drawbacks.

B) Means for Solving the Problems The present invention provides a semi-cylindrical delivery member whose rotation is controlled by a motor at the bottom of a storage column in which cylindrical products are stacked and stored, and the inside of the semi-cylindrical part of the delivery member is In this vending machine, the lowest order product is stored in the machine, and the product is sent out by rotation of a delivery member by a motor. The inner surface of the semi-cylindrical body is formed so that the outer circumferential surface of the product projects outward from the virtual outer circumference of the semi-cylindrical body when the product is housed in the semi-cylindrical body.

(E) Function The present invention provides an arrangement in which the inner surface of a semi-cylindrical delivery member for storing and locking a product is such that when the product is stored and locked, the outer circumferential surface of the product is located outside the virtual outer circumference of the semi-cylindrical body. The trap is formed so as to protrude to the bottom, so that when the sending member enters between the lowest product and the next product, the next product is not pushed up.

(v) Embodiment The drawings each show an embodiment of the product dispensing device according to the present invention, and (1) is a product storage column installed vertically within the main body of the vending machine. This storage column (1) is provided between a pair of left and right side plates (2) and (3) so that cylindrical products (A) can be stacked and stored in a row in a horizontal position.
The long products are stored in one row in the front and back direction, and the short products are stored in two rows in the front and back direction. A semi-cylindrical delivery member (4) is provided at the lower part of the storage column (1). The delivery member (4) is rotatably supported on the storage column (1) by shafts +5>(5) provided at the front and rear ends so as to be located at the center of the outer circumference of the semi-cylindrical body (4A). The delivery member (4) is formed into a semi-cylindrical body (4A) corresponding to approximately 120 degrees, and has an inner surface (4B) forming an arc along the outer peripheral surface of the product (N) to be stored and locked. When the product (A) is stored and locked on this inner surface (4B), the outer circumferential surface of the product (A) is formed on the extension line of the outer circumferential surface (4C) of the semi-cylindrical body (4A). (6) It is arranged to project outward from the position.

The delivery member (4) is driven by a drive motor (7) connected to the shaft (5), a cam (8) mounted on the shaft (5), and a motor (7) operated by the cam (8). It is designed to reciprocate by a predetermined angle using a switch (9) and a trap that control the rotation. On the other hand, in the case of a long product (A), one delivery member (4) is attached to the inner surface (4B) of the semi-cylindrical body (4A).
), and in the case of short product (A), 1 in the front and back direction.
It is formed so that two pieces can be stored and locked.

(11 is a product (B) with a smaller diameter than the product (A) above.
It is a regulating member that is removably attached when storing and locking the product (B), and the inner surface (
IOB) and an arcuate outer surface (IOC) corresponding to the inner surface (4B) of the semi-cylindrical body (4A), and when attached to the inner surface (4B) of the semi-cylindrical body (4A), As shown in FIGS. 7 to 9, the thickness of the inner surface (IOB) and outer surface (100) is eliminated at the leading end (4D) of the semicylindrical body (4A), and the inner surface (IOB) at the trailing end (4E) is )
and the outer surface (IOC) are formed so that the outer circumferential surface of the product (I31) to be stored and locked on the inner surface (IOB) extends from the vicinity of the leading end (4D) to the virtual outer circumferential circle (6). ) is positioned so as to protrude outward.

αυ is a delivery control member that is removably attached to the side plate (2) in the storage column (1) corresponding to the lower side of the delivery member (4), and is used to store short products (A) or short products (B) in the front and back.
It is attached when the products are stored in a row, and the delivery of the preceding and succeeding products is controlled alternately by rotating the delivery member (4) in stages. That is, when the delivery member (4) stores short products (A) or short products (B) in two rows, the delivery control member αυ is attached to the side plate (2) corresponding to the products in the rear, and This is to shift the timing at which the product and the product at the rear are released from the semi-cylindrical body (4A) and are sent out falling downward. Therefore, when the delivery control member αυ is attached, when the front product is released from the semi-cylindrical body (4A) and delivered, the rear product is separated from the semi-cylindrical body (4A) by the delivery control member αD. When the semi-cylindrical body (4A) continues to be locked in the state and the semi-cylindrical body (4A) further rotates a predetermined amount, the rear product is released from the lock between the delivery control member αυ and the semi-cylindrical body (4A) and is sent out falling. It has become. The stepwise rotational control of the delivery member (4) is performed by controlling the cams (8) and □, which rotate with the rotation of the delivery member (4), and the switch (9), which is operated by the operation of the cam (8). This can be achieved by changing the settings.

Next, the operation of this configuration will be explained. First, the product (7!
The product sending operation when the products are stored in front and rear rows will be explained.

In this case, the regulating member H and the delivery control member αυ are not attached. Fig. 1 shows the standby state, and the delivery member (4) stores and locks the lowest product (A1) in the semi-cylindrical body (4~), and the product (A1) is placed above the lowest product (A1). ) are stacked and stored.When a product delivery command is sent to the motor (7) and rotates, the delivery member (4) rotates clockwise around the shaft (5).The delivery member (4) A semi-cylindrical body (
The lowest product (A1) stored and locked inside 4A) has its outer peripheral surface projecting outward from the virtual outer circumferential circle (6) of the semi-cylindrical body (4A), and the next stage product is placed on the projecting part. Product (A2)
are stacked up, and the overhang dimension of this lowest product (A1) decreases and disappears as it approaches the leading end (4D) of the semi-cylindrical body (4A), so the delivery member (
Along with the rotation of step 4), the next-stage product (A2) descends and transfers onto the leading end (4D) of the semi-cylindrical body (4A). In other words, as shown in FIG. 2, the semi-cylindrical body (4A) has the leading end (4D ) can easily cut in and enter the semi-cylindrical body (4 people) on the outer peripheral surface (
4C) Lock the next product (A2) on top. Then, the sending member (4) is further rotated, and the trailing end (4E) and the side plate (2) are rotated.
When the distance between the product (A1) and the product (A1) becomes larger than the diameter of the product (A1), the product (A1) is released from the semi-cylindrical body (4A) and falls downward, and the cam (8) is activated by the switch (9).
) to work. Based on the operation of this switch (9), the motor (7) temporarily stops and starts rotating in reverse.

Due to this reverse rotation, the delivery member (4) rotates counterclockwise around the shaft (5), and the distance between the leading end (4D) and the side plate (2) becomes larger than the diameter of the next product (A2). At this point, the next product (A2) is released from the outer circumferential surface (4C), and the next product (A2) is received and stored on the inner surface (4B) of the semi-cylindrical body (4A), and is in a standby state. to return to. Note that the motor (power) is stopped based on the operation of the switch (9) by the cam (8).

Next, a description will be given of the product delivery operation when the products (A) are stored in two rows, front and back. In this case, the delivery control member aυ is attached. This product delivery operation is the same as the above-mentioned delivery operation for the front and rear rows until the product (AI-1) in the front part is dropped and delivered, so a description of that part will be omitted.

When the product (AI-1) at the front at the bottom falls and is sent out, the cam (8) operates the switch (9), and based on this operation, the motor (7) stops and the sending member (4) stops rotating. Stop. At this time, the rear product (AI-2) is locked between the trailing end (4E) of the semi-cylindrical body (4A) and the delivery control member αυ. When the product delivery command is delivered here, the motor (7) starts rotating, and the delivery member (4) again rotates clockwise about the shaft (5).

As shown in FIG. 4, when the distance between the trailing end (4E) and the delivery control member αυ becomes larger than the diameter of the product (AI-2), the product (AI-2) is suspended in the semi-cylindrical body (4A). The stop is released and the cam (8) is sent out downward.
operates the switch (9). Based on the operation of this switch (9), the motor (7) temporarily stops and starts rotating in reverse. Due to this reverse rotation, the delivery member (4) rotates counterclockwise around the shaft (5), and the leading end (4D) and the outer plate (2)
At the point where the distance between the next product (A2-t) (A2-2) and

In addition, the motor (7) is operated by a switch (9) using a cam (8).
will be stopped based on the action of

The delivery operation for small-diameter products, which is performed by attaching the regulating member α1 to the inner surface (4B) of the semi-cylindrical body (4A) of the delivery member (4), is the same as each of the above-mentioned delivery operations, and will therefore be omitted.

Although the reciprocating rotation of the delivery member (4) according to this embodiment is performed by rotating the motor (7) in reverse, the reciprocating rotation can be controlled by a known cam link mechanism to rotate the motor in one direction. You can also.

(G) Effects of the Invention The present invention provides an arrangement in which the inner surface of a semi-cylindrical delivery member for storing and locking a product is such that when the product is stored and locked, the outer circumferential surface of the product is larger than the virtual outer circumference of the semi-cylindrical body. It is formed so as to protrude outward, so that when the sending member enters between the lowest product and the next product, there will be no upward movement of the next product. Excessive load is not applied to the member. Therefore, the rotation of the delivery member becomes easier, the load on these rotation mechanisms and motors is reduced, and failures can be prevented, and the leading end of the delivery member It is possible to prevent damage to the next product due to this.
