In the above time stamp, when the measured temperature is printed on the paper, two operations, that is, a measurement operation for measuring the temperature and a printing operation for printing the measured temperature are required. Therefore, work efficiency is bad.

The above time stamp is handy. Therefore, when performing the measurement work for each of a plurality of processes in the distribution process, it is necessary for the worker to carry the time stamp and move to the measurement place of each process and perform the temperature measurement work for each process. . Therefore, the operator needs to carry a time stamp, and the work efficiency is also low in this respect.

Therefore, an object of the present invention is to provide a time recorder excellent in work efficiency.

The above-mentioned object is a time recorder that prints the time when a time card is inserted on the time card, and is based on temperature information output from a temperature measuring unit arranged outside the time recorder main body. This can be achieved by a time recorder comprising a temperature information acquisition unit that acquires temperature information and a printing unit that prints the temperature information on the time card together with the insertion time.

When the time card is inserted, temperature information at the insertion time is printed together with the insertion time. Therefore, the operator can print the insertion time and temperature information on the time card by a single operation of inserting the time card into the time recorder. In addition, when there are a plurality of locations to be temperature management targets, by installing a time recorder for each management target, the operator can visit each management target by hand. Therefore, the time recorder is excellent in work efficiency.

According to the present invention, a time recorder excellent in work efficiency can be provided.

Hereinafter, an embodiment according to the present invention will be described with reference to the drawings. FIG. 1 is an external view of a time recorder 10 according to the present embodiment. FIG. 2 is a configuration diagram of the time recorder 10. The time recorder 10 prints the time at the time of insertion of the time card on the time card, and based on the output signal from the temperature measuring device 40 arranged outside the time recorder main body, temperature information at the insertion time described later is the time card. To print.

As shown in FIG. 1, the time recorder 10 has a time recorder 10 having an insertion port 12 formed on the upper surface. The time recorder 10 is provided with a display unit 14, an operation unit 16, and a speaker 17 on the front. The display unit 14 includes a liquid crystal display, and displays the current date and time, time, and the like. The speaker 17 outputs a notification sound when the operation unit 16 is operated. A USB (Universal Serial Bus) interface 18 is provided on the side of the time recorder 10. The time recorder 10 is connected to the temperature measuring device 40 via the cable 19.

The card feeder 22 is a mechanism for determining the position of a time card (not shown), and includes a motor (not shown), a card insertion slot, a card detection switch and the like. Further, the card feeding unit 22 sucks the card to the line to be printed based on the control by the control unit 25, holds the time card during printing, and discharges the time card after printing to set the vertical position of the time card. Determine.

The printing unit 23 prints the time card insertion time and the temperature information at the insertion time output from the temperature measuring device 40 in the time card printing field. The printing unit 23 includes a print head, a motor, a carrier, and the like (not shown). The print head is supported by a carrier, and the carrier is movable in the horizontal direction by the driving force of the motor. Based on the control by the control unit 25, the printing unit 23 moves the print head to a horizontal position suitable for the printing column to be printed, and prints the time and temperature information supplied from the control unit in the printing column.

The timekeeping unit 24 is a timekeeping circuit including an oscillator, a counter, and the like (not shown), and measures the current time and calendar information (date, day of week, etc.).

The control unit 25 includes a CPU (Central Processing Unit) (not shown), a ROM (Read Only Memory) that stores a predetermined program, and a RAM (Random Access Memory), and controls the operation of the time recorder 10 as a whole. For example, the control unit 25 specifies a line and a column to be printed based on the stamp count in a printing process described later. Next, the control unit 25 controls the card feeding unit 22 and the printing unit 23 to move the print head to the position of the corresponding column, and prints the time card insertion time and temperature information at the time of insertion. The RAM serves as a work space for temporarily storing information necessary for CPU processing.

The control unit 25 is connected to the temperature measuring device 40 via the interface 27. The control unit 25 can acquire the temperature information output from the temperature measuring device 40 and temporarily stores it in the RAM. Thus, the control unit 25 also functions as a temperature information acquisition unit. The temperature output from the temperature measuring device 40 is output every predetermined time, for example, every minute, and the control unit 25 continuously stores the temperature temporarily in the RAM. The temperature information temporarily stored in the RAM may be configured to be constantly updated.

The storage unit 26 includes a nonvolatile memory such as a flash memory. When the control unit 25 detects the insertion of the time card, the control unit 25 reads temperature information at the time of insertion from the RAM and stores the temperature information in the storage unit 26. Specifically, the storage unit 26 stores a temperature history table (history information) in which the insertion time of the time card is associated with the temperature information at the insertion time. FIG. 3 is an exemplary diagram of a temperature history table stored in the storage unit 26. In the temperature history table, date, time, and temperature are associated with each other.

The USB interface 18 is an interface for outputting information related to the temperature history table stored in the storage unit 26 to an external information processing apparatus (for example, a personal computer). The USB interface 18 corresponds to an output unit. It should be noted that when information related to the temperature history table is output to an external information processing device, it is not limited to such a USB interface, and may be another connector, for example, a wireless communication means such as a wireless LAN. You may make it transmit automatically via.

The temperature measuring instrument 40 measures the outside air temperature around the temperature measuring instrument 40. The temperature measuring device 40 is configured by a known technique including a thermistor (not shown) whose resistance value changes depending on the temperature. The temperature measuring device 40 is not limited to the one provided with the thermistor, and any device that can measure the outside air temperature around the temperature measuring device 40 may be used. Good. Information about the temperature measured by the temperature measuring instrument 40 is output to the time recorder 10. The time recorder 10 is connected to the temperature measuring device 40 via the cable 19, but is not limited to this, for example, the temperature information output from the temperature measuring device 40 via wireless communication means such as Bluetooth is used as the time recorder main body. May be configured to receive.

Next, an example of the printing process executed by the control unit 25 will be described. FIG. 4 is a flowchart executed by the control unit 25. As shown in FIG. 4, the control unit 25 determines whether or not a time card has been inserted based on the output from the card detection switch (step S1). In the case of negative determination, the control unit 25 ends the printing process. If the determination is affirmative, the control unit 25 reads the current time based on the information from the time measuring unit 24 (step S2). Next, the control part 25 reads the temperature information temporarily memorize | stored in RAM (step S3). This temperature information is the temperature information output from the temperature measuring device 40. Next, the control unit 25 prints the read time and temperature information in a predetermined printing field of the time card by the printing unit 23 (step S4). When printing is performed, the control unit 25 reads the stamp count from the storage unit 26, and specifies the print field of the time card based on the stamp count value. As a result, the insertion time and the temperature information at the insertion time are printed on the time card.

Next, the control unit 25 stores the insertion time and temperature information at the insertion time in the nonvolatile memory of the storage unit 26 as a temperature history table (step S5). Note that the temperature information at the insertion time in this case is the temperature information temporarily stored in the RAM. The temperature history table stores a plurality of insertion times and a plurality of temperature information corresponding to the plurality of insertion times.

Next, an example of using the time recorder according to this embodiment will be described. FIG. 5 is an explanatory diagram of a usage example of the time recorder according to the present embodiment. As an example of use, assume the case of managing the temperature in a plurality of warehouses.

Each of the warehouses 100a to 100d is controlled to a predetermined temperature. In the warehouses 100a to 100d, time recorders 10a to 10d are installed, respectively. The temperature measuring devices 40a to 40d are disposed in the warehouses 100a to 100d, which are the targets of temperature management, respectively. The time recorders 10a to 10d are arranged outside the warehouses 100a to 100d, respectively.

The time cards 10a to 10d are preliminarily provided with time cards T1 to T4, respectively. The operator can print each temperature of the warehouses 100a to 100d on each of the time cards T1 to T4 by going through the time recorders 10a to 10d.

As described above, the time recorder 10 prints the insertion time and temperature information on the time card simultaneously with the insertion of the time card. Therefore, the operator can print the storage of the insertion time and the temperature information at the insertion time on the time card in one operation of inserting the time card. Therefore, the work efficiency of the worker is improved.

Further, since the time recorders 10a to 10d are arranged in the respective warehouses 100a to 100d, the worker can grasp the temperatures of the respective warehouses 100a to 100d without carrying the time recorder. Thereby, an operator's work efficiency improves.

Further, the time recorder 10 and the temperature measuring device 40 are connected via a cable 19. For this reason, the temperature information of the place away from the time recorder 10 can be acquired. Therefore, as shown in the above usage example, the temperature measuring devices 40a to 40d are arranged in the warehouses 100a to 100d to be measured for temperature, and the time recorders 10a to 10d are arranged outside the warehouses 100a to 100d. The operator can easily record the temperatures in the warehouses 100a to 100d without entering the warehouses 100a to 100d.

FIG. 6 is an illustration of a time card. As shown in FIG. 6, time and temperature are printed in association with each other on the time card.

Next, another example of use of the time recorder according to the present embodiment will be described. FIG. 7 is an explanatory diagram of another example of use in the time recorder according to the present embodiment. As an example of use, the case where the temperature of each process place is managed at a food processing place is assumed.

In a food processing plant etc., a time recorder is arranged at each place where the process is performed. Each process includes a pretreatment process place 200a, a frying process place 200b, a packing process place 200c, a freezing process place 200d, and the like. The time recorders 10a to 10d arranged for each process place are set so that the print fields for the time card T do not overlap each other.

FIG. 8 is an illustration of a time card. As shown in FIG. 8, the time and temperature at the pretreatment process field 200a are printed in the printing field 1, and the frying process field 200b, the packing process field 200c, and the freezing are printed in the printing fields 2 to 4, respectively. The time and temperature at the process place 200d are printed. In this case, the worker engaged in each process can print the time and temperature in each process using one time card T. That is, the worker engaged in the pretreatment process place 200a prints the time card T by the time recorder 10a arranged in the pretreatment process place 200a, and the time card T printed here is the next along with the food to be processed. It can be conveyed to the frying process place 200b which is the process. The time card T can be transported, for example, by placing the time card together with the food on a tray (not shown) for transporting the food and transporting the tray by a belt conveyor (not shown) that connects the processes. The time card T transported to the frying process place 200b is printed by the worker engaged in the frying process place 200b using the time recorder 10b placed in the frying process place 200b. The time card T on which the temperature at the frying process place 200b is printed is similarly transported to the next process together with the food.

Thus, since the time card T can be conveyed to each process together with the food to be processed, there is no need for a specific operator to go around each process and measure the temperature. Therefore, work efficiency is improved.

In addition, by using the time card T in this way, temperature information in each process can be integrated into one time card T, and the temperature in each process can be easily grasped. Moreover, the temperature in the previous process can be easily grasped for the worker engaged in each process.

In addition, in the food processing process, temperature control and time are closely related. That is, in order to maintain the quality of food, not only the current food temperature but also the time when each process is completed is important.

Here, the time stamp disclosed in Japanese Patent Laid-Open No. 2000-76504 will be described. The time stamp incorporates a non-contact type thermometer. The non-contact type thermometer is performed by irradiating a surface of an object to be measured with a laser beam and receiving the laser beam reflected from the object. Therefore, depending on the measurement work of the operator, there is a possibility that the temperature of the measurement target cannot be measured appropriately. That is, when an unskilled worker measures the temperature, there is a possibility that the temperature cannot be measured accurately. Further, every time the operator who performs temperature measurement changes, there is a possibility that the measured temperature varies. Therefore, the operator is always forced to perform accurate temperature measurement, and the working efficiency is deteriorated from this viewpoint.

However, in the time recorder 10 according to the present embodiment, since the temperature measuring device 40 is provided outside the time recorder 10, the operator is not forced to perform any special work necessary for accurate temperature measurement. Therefore, according to the time recorder 10 according to the present embodiment, even an operator who is unfamiliar with temperature measurement can easily measure, and there is no variation in measurement accuracy among workers.

Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to such specific embodiments, and modifications and changes can be made within the scope of the gist of the present invention described in the claims. Is possible.

The color of the temperature information printed on the time card T may be changed based on the temperature acquired by the control unit 25. For example, when the temperature acquired by the control unit 25 is not included in a predetermined range set in advance, the normal print color may be black, whereas the normal print color may be printed in red. . In this case, the printing unit 23 needs to include black and red ink ribbons.

The temperature measuring instrument 40 may be detachable from the time recorder 10 or may not be detachable.
