Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a vending machine that sells products while automatically controlling the temperature of the products. [Prior art and its problems] This type of vending machine uses a signal from a temperature sensor that turns on and off depending on the temperature of the product storage area in the vending machine to control the compressor motor of the cooling machine or the heater. heater (hereinafter referred to as cooling device, etc.)
Automatic sales are now possible by turning the power on and off to cool or heat the sold product to a set temperature. However, in conventional vending machines of this type, even at night when products are not sold, the cooling device is turned on by the signal from the temperature sensor.
The disadvantage is that it consumes unnecessary power because it is turned off during operation. One possible way to eliminate this drawback is to stop the operation of the vending machine during times when the operating rate of the vending machine is low. On the other hand, vending machines are installed in various locations, and operating conditions vary depending on the location. Therefore, even if a vending machine is configured to stop operating during a certain period of time when the operating rate is low in order to save energy, it is necessary to In order to operate a vending machine while saving power, various operating time patterns are required for the start and stop times of the vending machine. [Problems to be Solved by the Invention] However, no vending machine has conventionally been known that has various operating patterns that can meet this type of demand. This invention has been made in consideration of the above-mentioned circumstances, and includes storing anticipated operating time patterns in advance in a storage means such as a memory with a limited capacity.
Within that range, the operating time can be easily selected by operating a single mode setting switch, while a time setting device is provided to allow arbitrary operating time patterns to be set even outside the range stored in the storage means. It is an object of the present invention to provide a control device for a vending machine that can be set to start and stop the vending machine, thereby enabling power-saving operation according to various setting conditions. [Means for Solving the Problems] As shown in FIG. 4, the vending machine control device of the present invention includes an on-time setting device for setting the startup time of the cooling device, etc. of the vending machine, and a stop time setting device. an off time setting device, a mode setting switch that can be switched to multiple stages and generates a signal corresponding to each switching position;
A storage means that stores time modes consisting of multiple on times and off times for turning on and off the cooling device, etc., and an on time setting device when each time setting device is set to a predetermined time. a first starting means for starting the cooling device or the like according to a set time;
The first stop means stops the cooling device etc. when the time set by the off time setting device is reached, and when the on time setting device and the off time setting device are set to 0, it is set by the mode setting switch. a reading means for reading out the time mode from the storage means; a second starting means for starting the cooling device, etc. from the ON time of the read time mode; and a second starting means for controlling the cooling device, etc. to stop when the off time is reached. It is characterized by comprising a stopping means. [Function] Data indicating a predetermined driving time pattern is stored in the storage means. On the other hand, depending on the conditions such as the installation location of the vending machine, the desired operating time pattern can be set, such as starting at 6 a.m. and starting at 10 p.m.
If the pattern is a time stop, the desired operating time pattern is read out from the storage means by the mode setting switch. At this time, the on time setter and off time setter are set to 0. If the set time of each time setting device is 0, the reading means reads the on time, e.g., 6 a.m., and the off time, e.g., 9 p.m., from the memory means according to the setting value of the mode setting switch.
The second starting means drives the cooling device etc. to perform cooling at the set time, and at 9:00 a.m., the second stopping means stops the cooling device etc. until 6:00 a.m. the next morning. Stop vending machines to save electricity. On the other hand, if the desired operating time pattern is not stored in the storage means due to the installation conditions of the vending machine, desired on and off times are set in each time setting device. For example, if each time setter is set to "04" and "23", code signals indicating "4" and "23" are given to the first activation means and the second activation means. At 4:00 a.m., the first activation means activates the cooling device and the like to start cooling the product and perform normal temperature control. On the other hand, at 11 p.m., the first stop means stops the cooling device and the like. Therefore, cooling equipment etc. are stopped from 11:00 pm to 4:00 am the next morning to prevent unnecessary power consumption. [Embodiment] An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a motor for a compressor C of a cooler that cools products stored in a vending machine. The motor 1 may be replaced by a heater that heats the product. Compressor motor 1 detects the product temperature of the vending machine and turns off when the temperature is below the set temperature (turns on when the load is a heater) and turns on when it exceeds the set temperature (turns off when the load is a heater) It is connected to the power supply via the temperature sensor contact 10 and the relay X, and starts or stops the compressor by turning the temperature sensor 10 on or off.
When the temperature sensor 10 is on, that is, even if the temperature of the product exceeds the set temperature, if the relay X is off, the compressor motor 1 is forced to stop. 2 is a CPU (central processing unit) that controls turning on and off of the compressor motor 1, and a microcomputer is used. The output of the microcomputer 2 is connected to a transistor 11, and the transistor 11 turns on the relay X when an on command is issued from the microcomputer 2. 3 and 4 are on and off time setters, respectively, and each time setter 3 and 4 is equipped with a dial that can be set to any time from 0 to 24, as shown in FIG. Outputs the set time as a code signal. For example, when the ON time setter 3 is set to "04", a code signal representing "04" is generated.
Give it to CPU2. Also set the off time setter to "23"
When set to , the code signal representing "23" is sent to the CPU.
Give 2. Reference numeral 5 designates a mode setting switch that can be switched in multiple stages, and for example, a dip switch is used, and provides the CPU 2 with a signal corresponding to the set mode "1", "2", or "3". The CPU 2 is equipped with a clock device (not shown), and the CPU 2 compares the code signal applied from each time setting device 3 and 4 with the time data generated from the clock device, and sets the time using the ON setting device 3. At the set time, "1" is output to the output terminal 2-1 of the CPU 2 to turn on the transistor 11, and at the time set by the off time setting device 4, the output terminal 2-1 becomes "0". Transistor 11 is turned off. The ROM (not shown) of the CPU 2 stores the data shown in Table 1, as well as a program that performs the operations shown in FIG. , the transistor 11 is turned on and off according to the mode selected by the mode setting switch. .
The CPU 2 constitutes a storage means. Also CPU2, transistor 11 and relay 10
These constitute first and second starting means and first and second stopping means.

〔Effect of the invention〕

As described in detail above, according to the present invention, the cooling device, etc. is operated only during the time period set by the time setting device or mode setting switch, so that the cooling device, etc. is operated only during the time period set by the time setting device or mode setting switch. There is no need to waste power consumption by stopping equipment, etc., and the power saving effect can be increased. In addition, in this invention, a plurality of assumed start/stop time patterns are stored in the memory in advance, and a time pattern can be selected from among them, but operating conditions may vary depending on the installation location of the vending machine, etc. Even if the time pattern stored in memory cannot be used due to various changes,
By arbitrarily selecting the time pattern for starting and stopping using the time setting device, there is an advantage that the vending machine can be operated in an optimal time pattern while saving power, no matter how the operating conditions change.
