DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a product unloading device of an automatic vending machine according to an embodiment of the present invention, and FIG. 2 is a side sectional view of a main part thereof. In FIGS. 1 and 2, the same reference numerals as those in FIGS. 9 and 10 indicate the same or corresponding portions.

In FIG. 1, reference numeral 3a denotes a plurality of coaxially and mutually connected in a row with a phase shift of 90 degrees.
In the present embodiment, there are four rotary shafts projecting laterally from the side wall portions of the product receivers 2A on both sides of the product receiver 2, and as shown in FIG. 2, this rotary shaft 3a and the first pulley 4 are provided. The first clutch 9 is attached between the and.

Here, the first clutch 9 rotates by engaging with the rotary shaft 3a only when the motor 6 capable of forward and reverse rotation rotates normally, and in the present embodiment rotates clockwise. The shaft 3a is rotated together with the first pulley 4, and the rotary shaft 3a is rotated only when the motor 6 is normally rotated by the first clutch 9, and the four commodity receivers 2 are simultaneously rotated in the arrow A direction. It is like this.

Further, in FIG. 1, reference numeral 10 corresponds to the product receivers 2 which are connected to each other, and is connected to the leading ends of the product storage shelves 1 in a row so that the products 5 are connected as shown in FIG. The four product transport cams are product introduction members to be introduced into a predetermined product receiver 2.

Here, the commodity transfer cam 10 is formed in a rectangular shape and is thickened in the front end direction.
A rotating shaft 11 extending laterally from the product conveying cams 10a on both sides is pivotally supported in a predetermined vertical range. Then, normally, it is held at a standby position in which the moving hole 1b provided at the tip of the product storage shelf 1 is closed from below by a drive cam described later. In this standby position,
One product 5 is placed on the product transport cam 10.

An arm 12 is fixed to the end of the rotary shaft 11 so as to form a predetermined angle with the product transport cam 10. Here, the arm 12 abuts on an outer peripheral surface 13a of the drive cam 13 that is rotatably provided below and in which a partial recess is formed, and the rotating shaft 11 is fulcrum in association with the rotation of the drive cam 13. Is to rotate in the vertical direction.

A second clutch 16 is mounted between the shaft 14 of the drive cam 13 and the second pulley 15, and the second pulley 15 is driven in a direction opposite to the rotation direction of the motor 6. The second timing belt 7b is stretched in a state of intersecting so as to rotate the cam 13.

Here, the second clutch 16 is engaged with the shaft 14 of the drive cam 13 only when the motor 6 rotates in the reverse direction, in the present embodiment, when it rotates counterclockwise, the drive cam 13 is engaged. Is rotated together with the second pulley 15, whereby the drive cam 13 rotates in the direction of arrow B only when the motor 6 rotates in the reverse direction.

Therefore, the drive cam 13 rotates in the direction of the arrow B only when the motor 6 reversely rotates, whereby the arm 12 is first guided by the concave portion of the outer peripheral surface 13a of the drive cam 13 and pivots upward, In conjunction with this, the product transfer cams 10 of the product storage shelves 1 pass through the moving holes 1b and rotate upward to push the products 5 placed on the product transfer cams 10 obliquely upward in the transfer direction. Like

When the drive cam 13 continues to rotate,
Until the arm 12 comes out of the recess and slides on the outer peripheral portion of the drive cam 13, the arm 12 comes into contact with the recess again. It is designed to stay at a position where it can get over a product locking flange 1c which is vertically provided at the tip of 1.

On the other hand, the product 5 which has been pushed by the product transport cam 10 and has passed over the flange 1c is in a condition for receiving the product with the concave portion 2a facing upward like the product receiver 2 at the front of FIG. It is designed to be installed only in receiver 2.

Since the four product receivers 2 are out of phase with each other by 90 degrees, only one is ready for product reception, and the other three product receivers 2 are all ready for product reception. Therefore, the products 5 other than the products 5 introduced into the product receiver 2 are locked in the product receiver 2.

Then, the drive cam 13 further rotates,
When the arm 12 comes into contact with the recess again, the product transfer cam 10 rotates downward, and when the drive cam 13 has completed one rotation, the product transfer cam 10 returns to the standby position and the product receiver 2
The product 5 locked to is also returned to the original state accordingly. A spring 17 for urging the product transfer cam 10 downward is attached to the lower end of the product transfer cam 10. The spring 17 allows the drive cam 13 to move.
Is rotated once, the product transport cam 10 is surely returned to the standby position.

By the way, at a predetermined position of the vending machine,
A sales control device 18 shown in FIG. 3 is provided. Here, the sales control device 18 selectively drives the motor 6 to rotate the product receiver 2 and the product transport cam 10 to perform a sales operation.

That is, when the sale button 18a provided on the front of the vending machine is pressed, the motor 6 is rotated in the forward direction to rotate the commodity receiver 2 and the commodity storage corresponding to the sale button 18a is stored. When the product receiver 2 on the shelf 1 is ready to receive the product, a micro switch 19 described later is turned on, whereby the forward rotation of the motor 6 is stopped.

Further, the sales control device 18 then reverses the motor 6 to rotate the drive cam 13 this time to rotate the product transport cam 10 upward, and the product 5 is ready to receive the product. I am trying to install it in the receiver 2.

When the sale button 18a is pressed and the corresponding commodity receiver 2 is not in the commodity accepting state, the micro switch 19 is turned off, which causes the sale control device 18 to operate the motor. 6 is rotated in the normal direction, and when the product receiver 2 is rotated to be ready for the product reception, the micro switch 19 is turned on and the sales control device 18 stops the motor 6.

Further, when the drive cam 13 is rotated once, the sales control device 18 again rotates the motor 5 in the forward direction to rotate the product receiver 2 once, so that the product 5 introduced into the product receiver 2 is shot. After dropping it on 8, this product receiver 2
The product is stopped in a condition of accepting products and is prepared for the next product delivery.

By the way, as shown in FIG. 4, a ratchet mechanism 20 is provided on the side of the commodity receiver 2, so that the commodity receiver 2 does not turn over when not receiving power.

Further, for example, below the product receiver 2, a micro switch 19 for detecting that the product receiver 2 is ready to receive the product is provided. The micro switch 19 is provided on the side wall of the product receiver 2. It is adapted to be turned on and off by a cam 19a provided between the first pulley 4 and the first pulley 4.

When carrying out the product 5 placed on the predetermined product storage rack 1, the sales control device rotates the motor 5 forward until the micro switch 19 is turned on to store the predetermined product. The product receiver 2 on the shelf 1 is rotated until the product is ready to be received.

Next, the product unloading operation of the product unloading device thus configured will be described.

When a sales button 18a for a product 5 on a product storage shelf 1 is pressed, the sales control device 18 first rotates the motor 6 in the normal direction, and the rotation of the motor 6 is driven by the drive shaft 6a of the motor 6 and the first. It is transmitted to the first pulley 4 via the timing belt 7a.

At this time, since the rotation direction of the first pulley 4 is the direction in which the first clutch 9 fits with the rotation shaft 3a, the rotation shaft 3a of the commodity receiver 2 rotates together with the first pulley 4 and thereby The individual product receivers 2 rotate simultaneously.

Then, as shown in FIG. 5, the product receiver 2 of the product placing shelf 1 in which the product 5 to be sold is stored is in a condition for accepting a product, and when this is detected by the micro switch 19, the sales control device 18 Stops the rotation of the motor 6.

The second rotation of the motor 6 causes the second rotation.
Although the pulley 15 also rotates, the second clutch 16 does not engage with the drive cam 13 in this rotation direction, and therefore the drive cam 1
3 does not rotate.

Next, the sales control device 18 reverses the motor 6 and transmits the rotation of the motor 6 to the second pulley 15 via the drive shaft 6a of the motor 6 and the second timing belt 7b. The rotation direction of the second pulley 15 at this time is the direction in which the second clutch 16 fits into the drive cam 13 as shown by the arrow in FIG. 6, so the drive cam 13 rotates with the second pulley 15.

When the drive cam 13 rotates, the arm 12 moves from the concave portion of the outer peripheral surface 13a of the drive cam 13 along the outer peripheral portion, and in conjunction with this, the product transport cam 10 rotates upward from the moving hole 1b. By moving, the product 5 placed on the product carrying cam 10 is pushed upward in the carrying direction.

As a result, the product 5 eventually gets over the flange 1c of the product storage shelf 1 and is introduced into the product receiver 2a which is in a state of being ready to receive the product. At this time, the first pulley 4 rotates due to the reverse rotation of the motor 6, but in this rotation direction, the first clutch 9 does not engage with the rotating shaft 3a and the rotating shaft 3a does not rotate, so that the product receiver 2 rotates. There is no such thing.

Finally, the sales control device again rotates the motor 6 in the normal direction to rotate the product receiver 2 which is in a condition for accepting the product once, and as shown in FIG.
Then, the product 5 is carried out to the product outlet (not shown).

It should be noted that the products 5 other than the carried-out product 5 also get over the flange 1c by the product conveying cam 10 as shown in FIG. 8, but the product receiver 2a is not ready to receive the product, so it is introduced into the product receiver 2. Without being locked, the product receiving cam 2 is locked, the product transport cam 10 rotates downward, and the products 5 return to the product storage shelf 1.

As described above, the plurality of product receivers 2 coaxially connected to each other are simultaneously rotated so that one predetermined product receiver 2 is in a condition for receiving the product, and then the product transport cam 10 is rotated upward. The product 5 placed on the product transfer cam 10 can be introduced into the product receiver 2. Also, after this, the product receiving 2
Can be rotated once to drop the product 5 on the product chute 8 and can be carried out to the product outlet.

[0044]

As described above, according to the present invention, a plurality of product receivers are connected in a line by shifting the phase in the coaxial direction by a predetermined angle and are rotated by a single motor. This makes it possible to carry out the products separately with a simple structure.
