Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention provides an assembly part such as a panel material to be assembled to a main stage of a work stage into which a plurality of types of main parts are loaded. The present invention relates to a component specification instructing device for performing a carry-in operation according to the type of the main component.

(Prior Art) Among automobile assembly lines, for example, in the metal line process, the Automotive Engineering Complete Volume 19 “Car Manufacturing Method”
As shown on page 179 of the above, an assembly component such as a door panel is carried in and assembled to a main body formed of a large number of panel materials such as a floor main and body sides, that is, a vehicle body. This assembling is performed here while the body of the vehicle carried in by the conveyor is transported to a predetermined work stage. Adjacent to the stage, there is installed a support base for accommodating assembly parts to be assembled to the main body of the vehicle body. In this way, the work of assembling the assembly parts to the main body of the vehicle body while transporting the same is the same in the final assembly line after the painting work is completed. Also, in the main body process of assembling the main body, the body side and roof panel are assembled to the floor main, and in this process the metal body is the main part and the body side etc. are the assembly parts. Become.

In such an automobile assembly line, multiple types of vehicle bodies on the same line are mixed and transported in order to improve production efficiency. In doing so, a predetermined one corresponding to the vehicle body must be selected to carry in the work. For example, there are cases where it is necessary to assemble assembled parts made of different materials depending on the type of the vehicle body, even if they have exactly the same external shape.

Therefore, conventionally, a plurality of limit switches are installed at the entrance of the work stage to detect that the body of the vehicle has been conveyed to the entrance by the conveyor, and to detect the type of the body of the conveyed vehicle. There is. The detection of the vehicle type is made by detecting which of a plurality of limit switches provided so as to contact a characteristic portion of the vehicle body depending on the vehicle type. A non-contact sensor such as a photoelectric tube may be used instead of these limit switches. When such a sensor detects that the vehicle body has been transported to the work stage and detects its type, it lights up on a vehicle type indicator such as a lamp for indicating the vehicle type installed near the work stage in response to the signal. It is supposed to be done. Therefore, while checking the vehicle type by looking at the illuminated vehicle type indicator, the worker selects the type of a specific assembly component to be assembled in the body of the vehicle type, and installs a device for loading the component. Start up or pick up manually. As a result, the assembly parts are integrated with the vehicle body at that stage.

After the assembly work of the assembly parts as the main parts to the vehicle body is completed, or after the pickup operation is started, the operator confirms the assembly of the assembly parts corresponding to the vehicle body and presses the confirmation switch. When turned on, the lamp that displayed the vehicle type of the vehicle body goes out, and at the end of the assembly work for the vehicle body, the vehicle body is conveyed to the next process on the conveyor while the new vehicle body is carried in to the stage. It will be. Then, as described above, the new vehicle type is lit and displayed on the lamp, that is, the next vehicle information is output by the ON signal of the confirmation switch, and the assembly work of the vehicle body is sequentially repeated.

(Problems to be Solved by the Invention) However, in such a conventional method, the vehicle type of the vehicle body introduced into the entrance of a certain work stage is intermittently and sequentially sent by a signal from the sensor. Since the display of the vehicle type on the lamp is updated when the confirmation switch is turned on, if the operator forgets to press the confirmation switch, the body of the next vehicle type will be displayed with the original vehicle type displayed. Since it is carried into the stage, the worker may select a component different from the component originally assembled. Further, even when the confirmation switch is erroneously pressed a plurality of times, the actual vehicle type is different from the displayed vehicle type, and similar erroneous assembly occurs. If this happens, a specification error will occur.

The present invention has been made in view of the above-mentioned problems of the prior art, with respect to the main parts such as the body of the automobile body, when assembling the assembly parts such as a predetermined panel material corresponding to the type of the main parts, The purpose is to prevent erroneous assembly by an operator and improve assembly efficiency.

(Means for Solving the Problems) The present invention for achieving the above object includes a main part sensor provided on a work stage for carrying in main parts such as a vehicle body and detecting the main parts being carried in. A component support base for supporting the assembly component corresponding to the type of the main component,
Display means for displaying the type of the carried-in main part, and the main-part sensor which is operated by an operator after confirming the assembly of the assembly parts corresponding to the main part and by carrying-in the next main part. After the signal is input, the main part sensor has a confirmation switch for permitting the display of the type of the next main part on the display means, and an alarm device for emitting an alarm sound, and further, the main part sensor by carrying in the next main part. When the confirmation switch is turned on after confirming the assembly of the parts that have been carried in before the elapse of a predetermined reference time for the signal input timing from, the next new type of the main component after a certain time after the input of the signal Is displayed on the display means, and after the reference time has elapsed, the assembly of the already loaded parts is confirmed and the confirmation switch is turned on. Display means for displaying, and means for activating the alarm device when the confirmation switch is not turned on even if a predetermined alarm time elapses after the main part sensor is turned on when the next main part is carried in. It is a parts specification instruction device.

(Operation) In the above-mentioned present invention, a confirmation switch which is carried in by an operator after confirming the assembly of the assembly parts corresponding to the main parts, and a main part which carries in the next main part and detects the vehicle type thereof. If the confirmation switch is operated within a predetermined reference time after the next main component is conveyed, the operation timing of both the sensor and the sensor is detected in combination, and then the predetermined signal is output based on the ON signal of the main component sensor. While the type of the next main part is displayed on the display unit after the lapse of time, if the confirmation switch is activated after the reference time has elapsed since the sensor was activated, the predetermined amount is determined based on the confirmation switch being turned on. After the lapse of time, the type of the next main part will be displayed on the display, and if the confirmation switch is not operated even after a long time has elapsed since the main part sensor was activated, an alarm will be issued. I am trying to operate the vessel.

(Example) Hereinafter, the present invention will be described in detail based on an example of the present invention illustrated.

FIG. 1 is a schematic view showing a case where the present invention is embodied in an automobile assembly line, and a conveyor is provided on a work stage 10.
The main body 12 as a main component is transported by the 11, and the automobile assembly line is the stage described above.
A large number of 10 are installed at predetermined intervals, and the vehicle body 12 is sequentially transported to each stage 10.
A main component sensor 13 including a limit switch and the like is attached to the stage 10 in order to detect the type of the vehicle body 12 to which the stage 10 has been conveyed by the conveyor 11 and the loading time.

A component support base 15 is arranged adjacent to the stage 10 in order to carry a specific type of assembly component 14 corresponding to the main body 12 of the main component into the main body 12 of the stage 10. Further, a display device 16 including a display lamp and the like is installed adjacent to the stage 10, and this display device 16 has two types of body bodies 12 that are conveyed by the conveyor 11 in a mixed state. It has two lamps, and one of the lamps is turned on by a signal from the sensor 13. When there are three or more types of vehicles, the same number of lamps are provided. Furthermore, after confirming the assembly of the assembly parts corresponding to the vehicle body, it is operated by the operator, and at the same time, the main part sensor 13 by the loading of the next vehicle body 13
Adjacent to the stage 10 is a confirmation switch 18 that allows the display of the next type of vehicle body after the signal is input from the display device 16 and an alarm device that emits an alarm sound to the operator, that is, an alarm 19. Are arranged.

The signals from the sensor 13 and the confirmation switch 18 are adapted to be sent to the calculation means 20, and in response to these signals, the operation signals from the calculation signal 20 to the display 16 and the alarm device 19 are transmitted. It will be sent.

This computing means 20 is composed of a CPU, etc., and from the time when the first timer 21 that counts the time T1 after the confirmation switch 18 is turned on by the operator and the transportation of the vehicle body 12 and the vehicle type information by the sensor 13 are input. It has two timers, that is, a second timer 22 that counts the time T2, and calculates whether or not the confirmation switch 18 is turned on or the vehicle type information is input first, and the time difference between them. The calculation is performed by the unit 23, and signals are sent to the display 16 and the alarm 18.

First, before the vehicle type information from the sensor 13 is input, for example, assembling parts for the body body 12 that has already been loaded.
When the assembly work of 14 is completed and the operator confirms this assembly and turns on the confirmation switch 18, the confirmation switch 18
Indicator 16 that displays the vehicle type of the front body at the same time that the
Is turned off, and when the next new vehicle type information of the vehicle body 12 is input from the sensor 13, the second timer 22 starts counting. Then, when the count value T2 of the second timer 22 counts a certain time, for example, B time, the display 16 displays the information of the next vehicle type already sent from the sensor 13.
Light up. In this way, the sensor 13 that detects the vehicle type
When the second timer 22 which starts counting when the vehicle type information is sent from the vehicle is displayed the information of the next vehicle type when the reference time B is counted, the vehicle type information from the sensor 13 is input. The same applies when the confirmation switch 18 is turned on before the predetermined reference time B elapses even after the confirmation.

On the other hand, when the confirmation switch 18 is turned on after the elapse of the reference time B from the input of the next new vehicle body information of the vehicle body 12, the display of the previous vehicle model information is immediately erased and Based on the count value T1 of the first timer 21 that starts counting when the confirmation switch 18 is turned on, the next vehicle type is lit and displayed on the display unit 16 after a certain time C has elapsed. If the confirmation switch 18 is not turned on even when the second timer 22 that has been counting before the first timer 21 starts counting the predetermined time D, the alarm device, that is, the alarm 19 is activated. Generate an alarm sound. That is, the time D is the alarm sound generation time. This warning sound is stopped by turning on the confirmation switch 18, and as described above, the next vehicle type information is displayed on the display 16 after the time C has elapsed from the turning on of the confirmation switch 18.
Is lit up. These times B to D are set in seconds.

Under this condition, the operator can
Manipulate 14 into stage 10.

After this operation, the operator turns on the confirmation switch 18, but this ON operation is carried on to the entrance of the work stage 10 by the conveyor 11 to the next body body of the next vehicle body, and the sensor 13 detects this and outputs the signal. If is input before, it is determined to be YES in step 34. Then, display 16
In step 35, the display of the first vehicle type displayed in is deleted. After that, when the information indicating the next vehicle type is sent from the sensor 13 (step 36), the second timer 22 makes a step.
Start counting at 37. When the count value T2 of the timer 22 is determined to be the B time in step 38, the information of the next vehicle type is displayed on the display 16 in step 39. The control timings from step 34 to step 39 described above correspond to case 1 in the timing chart of FIG.

When it is determined in step 40 of FIG. 2 (B) that the next vehicle information is sent from the sensor 13 before the confirmation switch 18 is turned on, at the same time when the vehicle type information of the next vehicle is input, In step 41, the timer 22 is activated, and in steps 42 and 43, it is determined whether or not the confirmation switch 18 is turned on within the reference time B. If YES is determined in step 42, it means that the confirmation switch 18 is turned on before the second timer 22 counts the B time, and the vehicle type display of the previous vehicle is immediately extinguished in step 44. , Step
When the second timer 22 counts B time at 45, the vehicle type of the next vehicle is displayed as shown in step 39 described above. Such control of steps 42 to 45 corresponds to case 2 shown in FIG.

When the confirmation switch 18 is turned on after the lapse of the time B, that is, the reference time, in steps 46 to 48, it is determined whether or not the time when the confirmation switch 18 is turned on has passed the time D or more. If it is determined in these steps that the confirmation switch 18 has been turned on before the lapse of time D, the counting of the first timer 21 is started in step 49, and the display of the vehicle type is turned off in step 50. In this case, it is determined in step 51 that the flag is not set to "1", so in step 52 the count value T1 of the timer 21 is C
After waiting for the time to be counted, the next vehicle type is lit and displayed on the display 16 in the step 39. The time chart of steps 46 to 52 corresponds to case 3 in FIG.

If it is determined in step 48 that the timer T2 has counted the D time or more, the worker pushes the confirmation switch 18 even though the D time has passed since the next vehicle type information was sent by the sensor 13. Means not turned on,
The flag is set in step 53, and the alarm 19 is set in step 54.
Activate By the operation of this alarm device 19, the worker notices that he forgot to press the confirmation switch 18, and after confirming the work from himself, when the confirmation switch 18 is turned on, the timer 21 is counted at the step 49 through the step 46. Is started. In this case, the step 53
Since the flag has been set in step 51, YES in step 51.
Then, in step 55, the operation of the alarm device 19 is stopped.
Further, after the timer 21 counts up to C hours in step 56, the next new vehicle type is displayed in step 39. The timing chart from step 56 to step 39 corresponds to case 4 in FIG.

In the above-described embodiment, the limit switch detects the loading of the main body of the vehicle body, which is the main component, into the work stage. Is also good.
In that case, the host computer serves as the main component sensor, and from here, the carry-in to the work stage and the vehicle type information are sent.
