Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is suitable for efficiently performing a work mainly performed by human power, such as a process of assembling small parts such as a small electric motor and a small speaker, which have a simple structure to be assembled by a small number of parts. The present invention relates to a simple work time setting device, and more particularly to a device which is easy to use, has a simple structure, and is inexpensive to supply.

[0002]

2. Description of the Related Art Generally, the work of assembling small parts by manpower is short, so that it is not suitable for so-called conveyor-type assembly work, and the conveyor is merely positioned as a tool for physical distribution, and is constructed by many workers. Production is performed by parallel physical distribution processes. On the other hand,
In such a production system that does not use a compulsory conveyor, the worker does not have a compulsory force to finish the process in charge at a predetermined time, so the work progresses at the worker's own pace, making it difficult to improve production efficiency. It was

Therefore, in order to eliminate such inefficiency, it is also practiced to sound a buzzer each time one work time elapses and to instruct the operator to set the work efficiency at the interval of the buzzer. Further, if all the steps and works are advanced by the same buzzer, it is troublesome to adjust the work time required for each process (hereinafter, referred to as tact time) in a straight flow work to be constant. In parallel work, it was necessary to match the tact time to the person with the lowest efficiency, and there was a limit to improving work efficiency as a whole process.

[0004]

Therefore, in order to eliminate such problems, a buzzer is prepared for each worker when the parallel production system is adopted, and an interval at which the buzzer sounds is set for each worker. In addition, the set time can be adjusted by the workers themselves, and at the same time, the production status of all the workers is reported to the production manager every moment.

However, in order to perform such a complicated operation, a one-chip type microprocessor is required, so that ancillary work such as program setting is required, which is not convenient and the device itself. However, since the equipment itself is expensive and it is necessary to prepare the apparatus itself for each worker, there is a problem that the investment amount becomes very large in a workplace having a large number of workers.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object thereof is to construct a working time setting device arranged for each worker at a low cost. A setter 8 for accommodating the LSIC 11 and for inputting the planned production quantity as the input means of the LSIC 11 on the outer surface of the housing 3a and a result input 10 for inputting the production results are also used as the output means. While providing a planned quantity display 7a for displaying the planned production quantity for each hour, an actual quantity display 7b that operates according to the output of the actual performance input element 10, and an annunciator 7c for notifying the production pace, the actual performance input element 1 is provided.
It is characterized in that it has a take-out means 5 for taking out the output of 0 to the outside.

[0007]

When the operator operates the setter 8 provided on the housing 3a and inputs a predetermined time for one production, the LSIC 11 sends a signal to the alarm device 7c at a pace corresponding to the number of productions accordingly. At the same time that the container 7c is operated, the total number of products that must be completed by that time is displayed on the planned quantity display 7a. Further, when one piece is produced, the fact is input, and the cumulative result of production by the worker is displayed on the actual quantity display 7b, and at the same time, the information is taken out by the take-out means 5.
It is transmitted to the centralized totalizer 4 via the, and the overall work progress is grasped.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. FIG. 3 shows an example of a centralized control type production system using the work time setting device 3 according to the present invention. In the figure, 1 is a belt conveyor, which is composed of an endless belt 1b wound between a roller 1a and a roller (not shown), and is driven by an electric motor 1c. The electric motor 1c is a commercially available induction motor, which is operated at a constant speed by a commercial power source, but sometimes an inverter is interposed between the commercial power source and the speed so that the speed of the endless belt 1b can be adjusted to improve the production efficiency. It may be adjusted accordingly. The arrow on the belt 1b indicates the belt transfer direction. A workbench 2 is provided on the side of the conveyor 1 along the longitudinal direction thereof, and a worker P is arranged on each of the workbench. Reference numeral 3 denotes a work time setting device according to the present invention, which is installed on the workbench 2 toward the worker P. Reference numeral 4 is a centralized counter, and in this embodiment, a microcomputer including a personal computer is used as the centralized counter 4. The work time setting device 3 and the centralized totalizing device 4 are connected so as to be able to transmit information via a power supply or optical fiber which is a transmission means 5. That is, in this case, the work time setting device 3 acts as a terminal device of the centralized totalizer 4.

As shown in FIG. 2, the work time setting device 3 is composed of a metal casing 3a, and has three switches on the front face thereof, that is, a power switch 6a comprising a snap switch,
In addition to the temporary stop switch 6b and the reset switch 6c composed of a push button switch, two indicators 7a,
7b, a buzzer 7c as an acoustic display, a numerical setting device 8 and the like are provided. The indicators 7a and 7b are counters that display a desired number of digits using a red light emitting diode. The planned number indicator 7a and the actual number indicator 7
b. The numerical setting device 8 is composed of rotary mechanical switches of the same number as the desired number of digits, and the impedance corresponding to the numerical value selected by rotating the fingertip acts as an electric load of the LSIC 11 described later. The numerical setting device 8 does not necessarily have to be a mechanical switch, and it goes without saying that an arbitrary type can be adopted. An electric wire terminal plate 9 is provided on the back surface of the housing 3a. As will be described later, the terminal board 9 has a planned number output a connected to the planned number display 7a,
It is provided with an input terminal c for taking out the actual result number output b connected to the actual result number display 7b and for receiving a signal from the actual result input switch 10. Reference numeral 14 is an electric wire for connecting a power source unit 12 described later to a commercial power source.

The electrical wiring of the working time setting device 3 will be described with reference to FIG. The main part of the work time setting device 3 includes a commercially available large-scale integrated circuit (hereinafter referred to as LSIC) 11 and a power supply unit 12. 13 is the LSIC 11 and the power supply unit 1
It is a power supply line that connects with 2. A so-called counter type IC 5070 is used for the LSIC 11 and is connected to the switches, the display, or the terminal board 9 as shown in the drawing. In the figure, the arrows attached to the wires connecting those switches and the like to the LSIC 11 are
The direction of the arrow points to LSIC11 is LSI
The input circuit to C11 is shown, and the one pointing rearward is the output circuit. Note that the connection with two arrows attached to the power switch 6a indicates the power line 13,
This merely means to connect or disconnect either the input or the output of the power supply, and does not particularly indicate the connection state.

Next, the operation method and operation of the work time setting device 3 will be described. When the worker P gets to work, first, the work time setting device 3 which is a terminal device installed on his / her work table 2
Power switch 6
Insert a. This causes the setter 3 to start operating,
At this time, both the planned number display 7a and the actual number display 7b display "0". Next, the operator operates the numerical setting device 8 to input a production pace suitable for his / her work speed. After that, when the temporary stop switch 6b is turned on when the work is started, the planned number display 7a starts counting, and after a predetermined set time elapses, a buzzer 7c serving as an alarm outputs a time signal each time. Sent,
At the same time, the planned production number displayed on the plan display 7a is "1".
Is added to display the planned total production. In this way, the buzzer 7c continues to be sounded even after that, and the cumulative production number is sequentially increased.

The operator pushes the switch 10 as the performance input 10 when the product is completed. The performance input element 10 is not limited to the push button switch of this embodiment, and a proximity switch (not shown) is used, for example. For example, the proximity switch is installed on the conveyor 1, and when the worker moves the finished product to be placed on the belt 1b of the conveyor, it is possible to detect it and use it as a signal of product finish. Thus, when a signal indicating the completion of one product is applied, the display of the past record number indicator 7b changes from "0" to "1". In this way, the display of the actual result number display 7b is increased by one each time the actual result input switch 10 is operated, and the total production number is displayed. When the production speed is to be changed during the work, the temporary stop switch 6b may be temporarily turned off, or may be moved by moving the numeral of the numerical setting device 8 to make the setting. In addition, turn off the pause switch 6b and set the number,
If it is turned ON after the end of the resetting, the planned production cumulative amount that has been displayed until then is continuously counted.

The work time setter 3 and the centralized totalizer 4 are connected via an electric wire as a transmission means 5, and the planned number and the actual number are the terminals of the planned number output a provided on the electric wire connector 9 and the actual number. It is input to the centralized counter 4 through the terminal of the output b,
The number produced by everyone and the number produced by each individual are tabulated. As described above, the LSIC is adopted as the setter 3, and the configuration thereof is extremely simple, but the desired operation can be obtained without excess or deficiency, so compared to the case where a microprocessor is used for the setter 3, It does not require a program for operation, is easy to use and inexpensive.

[0014]

As described above, according to the present invention, the counter type LSIC 11 is housed in the housing 3a, and the setter 8 for setting the planned production quantity as an input means to the counter, the actual production quantity. A performance input 10 is connected as a means for inputting, and as an output means, a notification device 7c for issuing a time signal at a pace commensurate with the set number of productions, a planned number display 7a for displaying a cumulative production schedule, and Since the working time setting device 3 has a simple configuration without using a computer since it is provided with a performance number display device 7b for displaying the cumulative total of production results, the planned production amount, the production result, and the work pace are worked. Since it is notified to the user, it is easy to use and inexpensive. Further, there is an effect that the computer for centralized control which has been conventionally used can be utilized to enable efficient production and production control.
