[0006]
In addition, the interior of the main body case 1 is divided into an upper chamber 7 and a lower chamber by a partition plate 6 as a heat insulating panel in order to divide the storage temperature range of the product (for example, two chambers for hot beverage and cold beverage). Insulated into chamber 8. This partition plate 6 is normally in a closed state, and is configured to open and secure its trajectory when an X-axis transport mechanism 9a described later moves up and down.
[0007]
Inside the inner door 3, an XY transport mechanism 9 is provided with the front surface of each rack 4a as the XY coordinate plane. As shown in FIG. 10, the XY transport mechanism 9 includes an X-axis transport mechanism 9a that horizontally moves a bucket 10 that receives a product delivered from the box rack 4a, and the X-axis transport mechanism 9a that is vertical. It is comprised from the Y-axis conveyance mechanism 9b which moves to a direction, and is controlled by the control part which is not shown in figure.
[0008]
The X-axis transport mechanism 9 a includes an X-axis rail 11 that movably supports the bucket 10, a slide plate 12 that supports the X-axis rail 11, an X-axis motor 13 and a timing belt 14 that move the bucket 10, and the bucket 10. The X-axis motor stop sensor 15, the X-axis stop position sensor 16, the limit sensor 17, and the like, which are fixed to the bucket 10, for example, are formed on the X-axis rail 11. And slits 18 and 19 for position detection by the sensors 15, 16 and 17.
[0009]
The X-axis motor stop sensor 15 is for stopping the X-axis motor 13, and the X-axis stop position sensor 16 is for checking the position of the bucket 10 stopped by the X-axis motor stop sensor 15. Yes, the limit sensor 17 detects the right and left movement limit position on the X-axis rail 11 and performs an emergency stop.
[0010]
The Y-axis transport mechanism 9b also includes a pair of left and right Y-axis rails 20 that slide-support the X-axis transport mechanism 9a, a shaft 21 that passes over the top of the Y-axis rail 20, and rotates the shaft 21 to generate a timing belt. A Y-axis motor 23 that drives the X-axis transport mechanism 9a up and down by driving 22 and a Y-axis motor stop sensor 24, a Y-axis stop position sensor 25, which is fixed to the slide plate 12 and is composed of, for example, a transmissive optical sensor, In order to balance the weight of the limit sensor 26, the slit plate 29 fixed to the Y-axis rail 20 and having a number of slits 27, 28 for detection by the sensors 24, 25, 26, and the X-axis transport mechanism 9a. The balancer 30 is provided.
[0011]
The Y-axis motor stop sensor 24 is for stopping the Y-axis motor 23, and the Y-axis stop position sensor 25 is for confirming the position of the bucket 10 stopped by the Y-axis motor stop sensor 24.

It is comprised so that goods may be carried out from the outlet 33. FIG.
[0013]
Next, the position detection control of the bucket 10 will be described. In the Y-axis transport mechanism 9b, when the Y-axis motor 23 is energized, the X-axis rail 11 is raised. Since the Y-axis rail 20 has the slits 27 and 28 corresponding to each stage of the rack, the Y-axis motor stop sensor 24 detects the slit 27 and counts the number of detections. If it is determined that the target height has been reached based on the number of detections, energization to the Y-axis motor 23 is stopped.
[0014]
After the energization of the Y-axis motor 23 is stopped, the X-axis rail 11 continues to rise due to inertia (overrun) and stops at a position higher than the slit 27. If the Y-axis stop position sensor 25 detects the slit 28 when the X-axis rail 11 is stopped, it is determined that the X-axis rail 11 has stopped at the normal position.
[0015]
When the Y-axis stop position sensor 25 does not detect the slit 28 (when the overrun is small), the Y-axis motor 23 is energized for a certain time to finely adjust the stop position. If the slit 28 is detected after fine adjustment, it is determined that the X-axis rail 11 has stopped at the normal position. If not detected, this operation is repeated until detected.
[0016]
In the X-axis transport mechanism 9a, first, the X-axis motor 13 is energized to move the bucket 10 to the right. Since the X-axis rail 11 has slits 18 and 19 for position detection corresponding to each row of racks, the X-axis motor stop sensor 15 detects the slit 18 and counts the number of detections. When it is determined that the target position has been reached based on the number of detections, the energization to the X-axis motor 13 is stopped.
[0017]
After the energization of the X-axis motor 13 is stopped, the bucket 10 continues to move to the right due to inertia (overrun) and stops at a position to the right of the slit 18. If the X-axis stop position sensor 16 detects the slit 19 when the bucket 10 stops, it is determined that the bucket 10 has stopped at the normal position.
[0018]
When the X-axis stop position sensor 16 does not detect the slit 19 (when the overrun is small), the X-axis motor 13 is energized for a certain time to finely adjust the stop position. If the slit 19 is detected after fine adjustment, it is determined that the bucket 10 has stopped at the normal position. If not detected, this operation is repeated until detected.
[0019]
[Problems to be solved by the invention]
However, there are a wide variety of products for sale, and the XY transport mechanism 9 is configured to operate with high precision so as to be suitable for sales of these products. There has been a problem that various provisions have not been provided so far. In particular, when the time for which the partition plate 6 is open at the time of product sales is long, there is a problem that cold air and hot air are mixed, resulting in energy loss of cooling and heating.
[0020]
The present invention has been made in view of the above, and an object of the present invention is to provide a control method for a vending machine capable of efficiently opening and closing a partition plate at the time of selling a product and reducing energy loss of cooling and heating.
[0021]
[Means for Solving the Problems]
  In order to achieve the above-mentioned object, a control method for a vending machine according to claim 1 of the present invention includes a partition plate formed to be freely opened and closed by dividing the interior into a plurality of chambers, and a plurality of columns arranged in upper and lower stages. A product storage rack disposed in a row above and below the partition plate, a bucket for receiving a product delivered from the column at a front position of the product storage rack, and the bucket vertically and horizontally An XY transport mechanism mounted movably, and in a method of controlling a vending machine that opens and closes the partition plate when the product is sold, sells the product in the column located above the partition plate WhenWhen the ascending XY transport mechanism reaches a predetermined position, the ascending operation is temporarily stopped, and immediately after the partition plate is opened, the XY transport mechanism passes through the XY transport mechanism and the product is placed in the bucket. When the XY transport mechanism that receives and closes the partition plate and then descends is in a predetermined position, the lowering operation is temporarily stopped, and the XY transport mechanism is immediately after the partition plate is opened. The partition plate is closed by passing the product, and the product in the bucket is paid out to a product payout exit.
[0034]
After starting the sales operation, the XY transport mechanism is raised to a predetermined position. And it is judged whether the goods for sale are stored in the column arrange | positioned above a partition plate. If the product to be sold is stored in a column arranged below the partition plate, it is not necessary to open the partition plate.
[0035]
If the product to be sold is stored in a column arranged above the partition plate, whether or not the height information (count number) has reached a predetermined specified value when the XY transport mechanism is raised. When it is determined and reaches the specified value, the ascending operation of the XY transport mechanism is temporarily stopped, and the opening / closing motor of the partition plate opening / closing mechanism is energized to open the partition plate.
[0036]
Then, immediately after the partition plate is opened, the XY transport mechanism is raised again, the bucket is moved to the front of the column storing the products to be sold, and the product is received in the bucket. Energizing the open / close motor closes the partition plate and lowers the XY transport mechanism.
[0037]
Subsequently, it is determined whether or not the sale target product is stored in a column disposed above the partition plate. If the product to be sold is stored in a column arranged above the partition plate, whether the height information (count number) has reached a predetermined value when the XY transport mechanism is lowered When the specified value is reached, the lowering operation of the XY transport mechanism is temporarily stopped, and the opening / closing motor of the partition plate opening / closing mechanism is energized to open the partition plate. Then, immediately after the partition plate is opened, the XY transport mechanism is lowered again, the opening / closing motor of the partition plate opening / closing mechanism is energized to close the partition plate, and the XY transport mechanism is further operated so that the product in the bucket Is paid out to the product outlet and put into a standby state.
[0038]
On the other hand, if the product to be sold is not stored in the column arranged above the partition plate, it is not necessary to close the partition plate because it is not opened, and the XY transport mechanism is further operated. The product in the bucket is paid out to the product outlet and is set in a standby state.
[0039]
As described above, when the product is sold, the XY transport mechanism is temporarily stopped in the vicinity of the partition plate, and when the partition plate is opened, the XY transport mechanism is allowed to pass, and immediately after the passage, the partition plate is closed. The time during which the partition plate is opened can be greatly shortened, the mixing of cold air and hot air can be further reduced, and the energy loss of cooling and heating can be greatly reduced.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of a vending machine according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.
[0041]
Embodiment 1 FIG.
FIG. 1 is a block diagram showing a main part of a vending machine according to Embodiment 1 of the present invention, FIGS. 2 and 3 are perspective views schematically showing a configuration inside a main body case, and FIG. FIG. 5 is a table showing an example of column information. In the following description, members that are the same as or correspond to those already described are assigned the same reference numerals and redundant description is omitted, and only different points will be described.
[0042]
First, the overall configuration will be described with reference to FIGS. The open detection switch 40 and the close detection switch 41 are for detecting the open / closed state of the partition plate 6. The H / C switch 42 is for switching the temperature zone of the upper chamber 7 or the lower chamber 8 to hot or cold. The inner door switch 43 is for detecting the open / closed state of the inner door 3.
[0043]
Further, the hot air heated by the heating device 44 circulates in the upper chamber 7 by the internal fan 45, and the temperature of the upper chamber 7 is detected by the internal temperature sensor 46. Below the main body case 1, a condenser 47, a solenoid valve 48, an evaporator 49, an internal fan 50, and the like constituting the refrigeration cycle equipment are provided. The temperature of the evaporator 49 is detected by the evaporator temperature sensor 51, and the temperature of the lower chamber 8 is detected by the internal temperature sensor 52.
[0044]
The main control unit 55 controls the entire vending machine, and is connected to a main body control unit 58 that controls the XY transport mechanism 9 and the partition plate opening / closing mechanism 60 by a communication line 59. The opening / closing motor 61 is for operating an opening / closing mechanism (not shown) of the partition plate 6. In addition, a display unit (not shown) for displaying the internal temperature, the product price, the presence / absence of change, the sales status, and the like, and an input device (not shown) for inputting various information necessary for control by key operation are also mainly used. It is connected to the control unit 55.
[0045]
Next, the opening / closing operation (after step S10) of the partition plate 6 at the time of product sales will be described based on FIG. After the sales operation is started (step S11), it is determined whether or not the product to be sold is stored in the column 4a disposed above the partition plate 6 (step S12).
[0046]
By the way, the address information of each column 4a and partition plate 6 can be automatically set as follows. That is, first, after opening / closing the inner door 3 or turning on the power, the Y-axis transport mechanism 9b is operated to raise the X-axis rail 11 from the reference position to the upper limit position, while the Y-axis stop position sensor 25 or the Y-axis motor is stopped. The number of steps in the Y-axis direction is detected and stored based on the number of times the slits 27 and 28 are detected by the sensor 24. The upper limit position is detected by the limit sensor 26.
[0047]
Next, in order to detect the number of rows in the X-axis direction, the X-axis transport mechanism 9a is moved left and right. That is, the bucket 10 is moved from the reference position to the left end, and the number of inputs of the X-axis motor stop sensor 15 or the X-axis stop position sensor 16 is detected and stored. This number of inputs is the number of columns from the reference position to the left end. Then, the bucket 10 is moved from that position to the right end. The left and right limit positions are detected by simultaneous input from the X-axis motor stop sensor 15 and the limit sensor 17.

Next, the bucket 10 is moved from the right end to the reference position, and the number of inputs (number of columns) of the X-axis motor stop sensor 15 or the X-axis stop position sensor 16 is detected and stored. This number of inputs is the number of columns from the right end to the reference position. Therefore, the total number of columns in the X-axis direction can be obtained by summing up the numbers of left and right columns from these reference positions.
[0049]
Then, the Y-axis transport mechanism 9b is operated to lower the X-axis rail 11 to the reference position, and the operation of the XY transport mechanism 9 is finished. The Y-axis counts obtained in this way are registered in order from the largest numerical value, and the X-axis count numbers are registered in sequential order from the smallest numerical value. For example, when the Y-axis count number is 0 to +7, the X-axis count number is −2 to +2, and the position of the partition plate 6 is the fourth stage, the relationship between the column number, each axis count number, and the operation of the partition plate 6 is as follows. As shown in FIG.
