Is an open / close detection switch for the flapper 13, 15 is a detection switch for a product that has been paid out of the product storage column and entered the bucket unit 6, 15a is a switch actuator, 1
Reference numeral 6 denotes a shaft-shaped (round bar) transport roller which bridges the bucket case 11 at the rear middle position and takes in the products paid out from the column 5 into the bucket case. Reference numeral 17 denotes a transmission between the transport roller 16 and the drive motor 12a. A timing belt 18 for connection is provided so as to protrude and retract from the rear surface of the rack case 11, and a connection gear (a gear for transmitting power to a product delivery mechanism of a product storage column) which is operatively connected to the transport roller 17; A pin pusher that protrudes from the rear surface of the case 11 to open and close the gate mechanism of the product storage column, 19a is a feed screw of the pin pusher 19, 19b is a pusher motor, and 20 is a product stopper that is bridged over the front upper part of the rack case 11 (in a bucket). The captured product is controlled to a standing posture), and 21 is a stop position sensor (X-Y).
A sensor that detects a stop position of the bucket unit 6 that moves along the X-axis transport unit of the transport mechanism (see FIG. 4), 22
Is a guide roller of the bucket unit 6. In this configuration, when the bucket unit 6 moves from the standby position (home position) and accesses the position of the commodity storage column selected by the customer, first, the pusher motor 19b is started to push out the pin pusher 19, and the commodity storage column is pushed out. Gate mechanism 5a is opened. In conjunction with the advance of the pin pusher 19, the connecting gear 18 protrudes from the bucket unit 6, and meshes with the drive gear of the commodity discharging mechanism on the column side. Next, the conveyor motor 12a is started, and its power is transmitted to the pusher-type product discharging mechanism of the column, and the products arranged in the front row of the column are discharged to the bucket unit 6. Here, when the product paid out from the column enters the inside of the bucket case 11 (the product is pushed forward from the rear and falls down to the forward inclined position), the product detection switch 15 is activated, and this switch operation signal is generated. Based on pin pusher 19
Is retracted to close the column gate mechanism 5a (see FIG. 3). Subsequently, the Y-axis transport unit 7y of the XY transport mechanism 7 (see FIG. 4) is slightly raised, the product is scooped up by the transport roller 16, and the product is further transported by the transport roller to transfer the product to the bucket case 1.
Take in one. In this case, the product has its top front end leaning against the product stopper 20 of the bucket unit 6,
The bottom surface is transported forward on the transport roller 16, whereby the product falls on the belt conveyor 12 in an upright posture. FIG. 6 is an explanatory view of the above-described product taking-in operation. As shown, the product 23 is taken into the bucket case 11 in an upright posture through the states I to V. And
When the product placed on the belt conveyor 12 is sent forward and pushes the bucket flapper 13 from the inside, the bucket flapper 13 is slightly opened and the open / close detection switch 14 is reversed, so that the conveyor motor 12a is stopped by this operation signal. I do. In this state, the bucket flapper 13
Of the bucket guide frame 7x-3 of the X-axis transport unit 7x shown in FIG. 4 does not fully open.
That is, the bucket guide frame 7x-3 is provided with a notch in the window frame so that the bucket flapper 13 can be opened only at a position corresponding to the home position of the bucket unit 6, and this home position is used for storing the products arranged side by side. The rack 4 is set at an intermediate position between the columns, and at an access position to the column, the bucket flapper 13 is restrained in a half-open state to hold the product in the bucket case 11. Then, by the transport operation of the XY transport mechanism 7, the bucket unit 6 is moved to the product outlet 2a (FIGS. 2, 3).
When the home position is reached, the conveyor motor 12a is started again to rotate the belt conveyor 12. As a result, the product is provided at the bucket flapper 13 and the product outlet of the inner door 3 (see FIG. 3).
Push the product open from the bucket unit 6 while opening
a. When the product is carried out to the product outlet 2a, the bucket flapper 13 returns to the closed position, the open / close detection switch 14 performs a return operation, and the conveyor motor 12a is stopped by this operation signal to end a series of sales operations. . This series of selling operations is performed by a program command from a control unit (not shown). [0012] By the way, there is no problem in selling canned goods, paper-packed goods and the like by the above-mentioned vending machine, but odd-shaped goods such as PET bottle goods (beverage goods). When the product is sold, the following transport trouble occurs when the product is taken into the bucket unit as described below. That is, as shown in FIG. 7 (a), the PET bottle product 24 is a container of a resin molded product having a smooth surface, and a recess 24a is formed on the bottom surface thereof. For this reason, when taking in the bucket unit 6 the PET bottle product 24 paid out from the product storage rack, the product 24 riding on the transport roller 16 in the state of IV shown in FIG. In some cases, the bottles 24 run idle, which causes the PET bottle product 24 to stagnate at this position and become unable to be taken into the bucket case 11, thereby causing a transport trouble. [0014] The present invention has been made in view of the above points. In the case of selling a deformed product such as a PET bottle product by the above-mentioned vending machine, the product paid out from the column of the product storage rack is stored in the bucket unit. It is an object of the present invention to provide an improved vending machine so that the vending machine can be reliably taken in. According to the present invention, in order to achieve the above-mentioned object, products are lined up in front and rear in a cabinet of a main body case having an outer door with a product outlet on the front surface. Equipped with a product storage rack in which columns to be stored side by side are arranged in upper and lower rows, left and right rows, and a bucket unit mounted on the XY transport mechanism and arranged in front of the product storage rack, in front of the column selected based on the sales order. A vending machine that accesses the bucket unit, transfers the goods paid out from the column into the bucket, and carries out the goods to the goods outlet.The bucket unit is laid over the rear middle position to transfer the goods from the column. In a device provided with a shaft-shaped conveyance roller to be taken into a bucket, a projection is provided on the circumference of the conveyance roller along the longitudinal direction thereof. According to the above arrangement, in the process of taking in the goods discharged from the columns of the goods storage rack into the bucket unit, the goods riding on the transport rollers slip by the operation of scraping out the projections due to the rotation of the transport rollers. Without
It is sent forward and is reliably taken into the bucket case. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to an embodiment shown in FIGS. 1 (a) to 1 (c). That is, fin-shaped protrusions 16a are integrally formed on the circumference of the shaft-shaped transport roller (for example, made of rubber) 16 incorporated in the bucket unit 6 along the longitudinal direction. With this configuration, when selling the PET bottle product 24, the bucket unit 6 is removed from the product storage rack.
As shown in FIG. 1 (c), the fin-shaped protrusions 16a send the plastic bottle product 24 forward as the transport roller 16 rotates. Therefore, the PET bottle product 24 is reliably sent forward without the transport roller 16 idling. This allows
The PET bottle product 24 can be reliably taken into the bucket unit 6 in the same manner as the paper pack product, and can be landed on the belt conveyor 12 in the upright posture as described in FIG. The fin-like projection 16a of the transport roller 16
Is effective not only for PET bottle products but also for paper pack products, cans, bottle products, etc., whose surfaces are wet and slippery, into the bucket unit. As described above, according to the present invention,
By providing protrusions on the circumference along the longitudinal direction of the transport roller for taking in the product incorporated in the bucket unit, even when selling odd-shaped products such as PET bottle products, they were paid out from the product storage rack. Products can be reliably taken into the bucket unit, and the reliability of the vending machine is improved.
