The present invention relates to a product dispensing apparatus of a vending machine.

In the prior art, the cam plate is rotated at a predetermined angle on the basis of the sales instruction to release the contact between the container and the cam plate to discharge the goods stored on the container, and the goods are transferred to the product receiving unit by the conveying device. In addition, Japanese Patent Laid-Open No. 62-134786 discloses a configuration in which the conveying device is reversed when the conveying device is stopped due to a product jam.

In the above-described configuration, the cam plate is rotated by the driving device by the sales force, so that the shock with the receiving table is released.

At the same time, the second lowest product falls on the barconveyer (transporter) while the second lowest product is pushed to the wall to support it.

After the product falls, the bar conveyor is driven to return the product to the merchandise outlet.

If overcurrent flows to the driving motor of the bar conveyor while the goods are being conveyed by the bar conveyor, the goods can be returned after the bar conveyor is reversed and then rotated forward to release the jam.

When the goods are returned, the bar conveyor is stopped and the cam plate is driven, thereby pushing up the container to release the second product.

However, in the above-described conventional technique, the bar conveyor is driven in the state in which the container is opened, so that the product is easily caught in contact with the container in which the product is open.

In addition, the receiving zone is open until the goods are returned to the product outlet, and the second product is in a state of being pushed against the wall, but the weight of the product above the second product is hung on the second product, and long-term support I can't stand it and I'm likely to send it out.

In addition, when the product is returned to the merchandise outlet and the occupancy bar is closed, the time to stand-by for the next merchandise is lengthened, and the sales time when the merchandise is continuously sold is prolonged and the sales opportunity is lost. There was a thing.

Therefore, while the bar conveyor is being driven, the operation of closing the receiving stand is performed, so that the receiving stand is rotated so that it is difficult to come into contact with the product, and the second product is supported early in the receiving stand before the next product is sold. The waiting time can be shortened. However, if the product is caught in contact with the container and bar conveyor, if the drive driving the container detects the stop, stop the drive to protect the device. Sold out the column.

Therefore, even if the jam is eliminated as the bar conveyor is reversely rotated, the column where the jam occurs is sold out and the next product cannot be sold.

Accordingly, an object of the present invention is to provide a product dispensing apparatus of a vending machine which can shorten the time until the standby state after the product sale and sell the product of the column whose jam has been eliminated without being sold out.

In order to solve the above problems, the present invention is an accommodating part for mounting and storing the goods, a receiving stand having one end axially supported to be installed at the lower end of the accommodating part so as to be rotated downward, and horizontally at a lower position of the receiving stand. A semicircular cam plate axially supported to rotate, and a first driving means for driving the cam plate, and driving the first drive device based on the sales instruction, and rotating the cam plate at a predetermined angle to contact the receiving table and the cam plate. A vending machine configured to release the product stored on the receiving table by discharging the product, and driven by the second driving means, based on the conveying apparatus and the sales instruction for conveying the product discharged from the receiving table to the product receiving unit. First control means for driving the drive means to rotate the receiving table to a lower position to perform control of delivering the goods onto the conveying apparatus; Controlling driving the drive unit to the upper position by driving the first drive means while the second drive device is being driven while driving the second drive device to convey the goods sent on the transfer device to the goods storage unit. The second control means, the first detecting means for detecting the stop of the first driving device, the second detecting means for detecting the stop of the second driving device, and the second driving device if the second detecting means detects the stopping. A reverse rotation means for reverse rotation is provided, and the second detection means detects the stop of the second drive device at least earlier than the timing at which the first detection means detects the stop.

According to the above arrangement, the second detection means detects the stop of the second drive device at least earlier than the timing at which the first detection means detects the stop, so that the first drive device and the second drive device are made of the same product. Even if it is stopped, the second drive device detects the stop and rotates in reverse, thereby releasing the stop of the first drive device and not detecting the stop of the first detection means.

The goods storage column 3 is arranged to face up and down the goods storage column 5 and the goods storage column 5 which store goods up and down, store them, and send them out of the lowest goods based on a sales order. The conveying apparatus 7 for pushing and conveying the goods sent out from (5) to the goods accommodating part 6 corresponding to the goods extraction opening which is not shown in the main body door 2 is provided.

In the machine room 4, mechanical devices, such as the compressor 8 and the condenser 9, for cooling or heating the inside of the goods storage 3 are arrange | positioned.

The merchandise storage columns 5 are arranged in five rows horizontally, in which three connected goods are connected back and forth in the merchandise storage 3.

Each merchandise storage column 5 is composed of a first storage portion 5A on the front side and a second storage portion 5B on the rear side, and a delivery device is installed at the outlet 5C provided at the bottom of each storage portion. It is.

The dispensing apparatus is provided with a first receiving table 10A and a second receiving table 10B, and rotation of the first and second receiving tables 10A, 10B downward is performed by a single cam plate 11. It is regulated.

The cam plate 11 is fixed to the tip of a cam shaft, not shown, so as to be horizontally rotated in a semicircular shape.

The cam shaft is driven by the column motor 12, which is the first driving device, and when the column transfer switch 12A rotates 90 degrees, it is turned "ON" and the rotation position is detected.

13A and 13B are pushed out by the cam body 14 fixed to the camshaft as a 1st, 2nd stopper, and 2 from bottom of the 1st, 2nd column 5A, 5B. The second product is pushed onto the storage wall 5D to support the second or more loaded goods.

The conveying apparatus 7 is installed in the above goods storage column 5 facing downward and mounts the goods carried out from the goods storage column 5, and introduces goods into the goods receiving part 6 with the front end 14A. The table 14 provided with the guide part 15, the 1st pulley 16 provided in the both sides by the front end of the table 14, and the 2nd provided in the both sides of the middle of the table 14. The pulley 17, the third pulley 18 provided on both sides at the rear end of the table 14, the chain 19 hypothesized by the first, second and third pulleys, and at least wider than the size of the product A drive shaft 21 connecting the plurality of pushers 20 and the first pulley 16 attached to the chain 19 at a predetermined interval and a first drive pulley connected to the drive shaft 21. (22), the second driving pulley (24) connected through the first driving pulley (22) and the drive chain (23), and the second driving field for applying driving force to the second driving pulley (24). Consists of the transport motor 25, a projecting portion 26 and the conveying carrier switch 27 for detecting the passage of the projection projecting from a portion of the drive chain (23).

The pusher 20 moves on the table 14 toward the product receiving portion 6 by the forward rotation of the transfer motor 25, and is guided to the second pulley 17 to move along the inclination of the tip portion 14A. do.

When the direction of the pusher 20 is changed by the first pulley 16, the chain 19 is guided by the chain guide part 28 to move the bottom of the table 14 toward the third pulley 18.

When the direction is switched by the third pulley 18, the table 14 is moved again toward the product receiving portion 6.

When the transfer motor 25 rotates in reverse, the pusher 20 moves in reverse to the above.

The actuator 27A of the carrier carrier switch 27 extends from the second driving pulley 17 toward the almost normal state in which the direction of the projection 26 is switched, and the projection 26 is rotated even if the driving chain 23 rotates forward and backward. ) Is easily detected.

Reference numeral 28 denotes a control device, and at least the transfer motor 25, the transfer carrier switch 27, the column motor 12, and the column carrier switch 12A are connected. It also sells and is also a first control means, a second control means, a first detection means, a second detection means and a reverse rotation means.

Next, the operation of each part will be described with reference to the flow chart art. First, when a currency is sent to a money processing device (not shown) and a product selection switch (not shown) is operated, the control device first goes to step S1. Proceed to drive the column motor 12.

When the column carrier switch 12A is turned "ON" in step S2, it progresses to step S3 and the column motor 12 is stopped.

This means that the goods are sent out from the goods storage column.

That is, when the column motor 12 is driven, the cam shaft 11 is rotated by rotating the column shaft and stopped when the column motor 12 is rotated 90 degrees.

The cam plate 11 is semi-circular and releases the regulation of either the first receiving seat 10A or the second receiving seat 10B.

In this case, if the regulation of the second accommodating table 10B is released, the second accommodating table rotates downward, releases the support of the lowest commodity, and drops the commodity onto the table.

At this time, the second product from the lowest is connected to the column shaft, is driven in synchronism with the cam plate 11, and protrudes toward the second storage part side where the cam plate 11 is opened to compress the stopper 13B.

The stopper 13B pushes the goods onto the storage wall 5D to hold the goods mounted above the second one.

In step S4, the transfer motor 25 is rotated forward, and at step S5, the column motor 12 is rotated forward.

When the transfer motor 25 rotates forward, the second drive pulley 24 rotates, thereby driving the drive chain 23 to rotate the first drive pulley 22.

When the drive shaft 21 rotates by the rotation of the first drive pulley 22, the first pulley 16 rotates and the chain 19 drives.

The chain 19 moves on the table 14 in the direction in which the pusher 20 moves in the direction of the product receiving portion 6.

Therefore, the goods sent out on the table 14 are compressed by the pusher 20 and move in the direction of the goods receiving part 6.

When the column motor 12 rotates forward, the column shaft rotates to rotate the cam plate 11.

When the cam plate 11 rotates, it contacts the open 2nd receiving stand 10B and rotates 2nd receiving stand 10B upwards.

Then, the flow advances to step S6 to determine whether the conveying apparatus 7 is stopped.

The stop of the conveying apparatus is mentioned later.

If the conveying apparatus 7 is not stopped, it progresses to step S7 and the stop of the goods storage column 5 is detected.

The stopping of the merchandise storage column 5 will also be described later.

If the goods storage column 5 is not stopped, it progresses to step S8 and step S9 and it detects whether the column carrier switch 12A is "ON" and whether the conveyance carrier switch 27 is "ON".

If the carrier carrier switch 27 is not turned "ON", it returns from step S6 and repeats detection.

As shown in FIG. 3, the stop of the conveying apparatus 7 is inserted into the second receiving table and the pusher 20 so that the conveying apparatus 7 of the commodity receiving section 6 Direction, or as shown in FIG. 4, the product is inserted into the product guide unit 15 and the pusher 20 so that the conveying device 7 is not driven in the direction of the product receiving unit 6. to be.

In normal conveyance, the projection part 26 compresses and drives the actuator 27A in step S9, and detects that the conveyance carrier switch 27 is "ON", three times. [Products sent out from the lowermost product storage column 5 are commodities. If it is determined that the pusher 20 has been moved enough to convey to the receiving section 6, the flow advances to the stem S10 to stop the conveying motor 25 to be in a standby state for sale.

In step S6, the stop detection of the conveying apparatus 7 starts to start the clock of the patch timer which driven the conveying motor 25, and it is three times that the said conveyance carrier switch 27 became "ON" within 3 second. If it does not detect, it will stop and proceed to step S14.

When the process proceeds to step S4, the conveying motor 25 is rotated in reverse for 0.5 seconds to proceed to step S15. After the product is caught while the conveying motor 25 is stopped, the flow proceeds to step S16. The product is returned to the product accommodating part 6 while being rotated forward.

The flow advances to step S17 to detect that the carrier carrier switch 27A is turned "on" four times (increasing the detection of the carrier carrier switch corresponding to 0.5 seconds or more in order to rotate it forward as long as it is reversed). If it does, it progresses to step S10 and the conveyance motor 25 is stopped and it is made to wait for sale.

If the goods are still stuck in step S17, the conveying apparatus 7 stops, and if the conveying carrier switch 27A is not "ON", it stops, and it progresses to step S18 to stop the conveying motor 25, and the step Proceed to S19 to display the sold out to stop the sale.

As the stop of the goods storage column 5 shows in FIG. 3, the goods sent out from the goods column 5 are caught in the 2nd receiving stand and the pusher 20, and the 2nd receiving stand cannot be rotated back, and a cam board (11) is in the state which abuts the 2nd accommodation stand, and cannot rotate.

In the normal rotation, if it is determined that the column carrier switch 27 is "ON" in step S8 (the cam shaft rotates by 90 °), the flow advances to step S13 to stop the column motor 12. do.

In step S7, the stop detection of the goods storage column 5 starts the timer counting from the time when the column motor 12 is driven, and the column carrier switch 12A mentioned above is turned "on" within a predetermined time. If it does not detect, it stops and it progresses to step S11 and a sellout display is performed.

Then, the product storage column 5 is sold out and the flow proceeds to step S13 to stop the column motor 12.

That is, according to the present invention, when the conveying motor 25 of the conveying apparatus 7 and the column motor 12 of the merchandise storing column 5 are driven at the same time, the product is filtered so that the conveying apparatus 7 and the merchandise storing column 5 Stops the conveying apparatus 7 after detecting that the conveying apparatus 7 is stopped even when the conveying apparatus 7 is stopped, the conveying motor 25 is rotated in reverse while detecting that the conveying apparatus 7 is stopped. Is not released and the product storage column is not sold out.

According to the present invention described above, the conveying device is driven so that it is difficult to come into contact with the product while the second conveying device is being driven while the second conveying device is closed, and the second product is mounted on the delivery device early. The waiting time before the next product is sold can be shortened.

In addition, when the product is caught by the product coming into contact with the delivery device and the delivery device, the first drive device driving the delivery device detects the stop of the second drive device and rotates the second drive device back in advance, rather than detecting the stop. The product can be sold without causing the product storing column which has a jam to be sold out by making the product stop and stop the product stopping.
