Description of the Related Art Conventionally, in a panel manufacturing line such as a remote monitoring control panel, after a panel manufacturing operator grasps the contents of the operation while referring to a drawing for a panel manufacturing operation created in advance by a designer such as an electric machine. In addition to selecting the tools required for manufacturing, taking out the necessary items for assembling the board from the stocked place, transporting it to the board assembling place, many workers gather at the center of the board to be assembled, and The method of assembling is adopted.

[0003] The procedure for assembling the board is such that, in addition to the setup of supplies and tools, an operator directly enters the housing and assembles the unit, while the cable working is performed in the same manner as the above-mentioned working drawing. It is carried out around the panel assembly place while watching In this method, each worker grasps only the task at hand and, after the task is completed, the next worker enters the cabinet and proceeds with the task.

[0004]

Accordingly, in the above-described method for manufacturing a control panel, a serial operation is performed such that the small unit operation is completed according to the operation procedure and the next small unit operation is performed. The period is long and very inefficient. Further, since the plurality of small unit works are performed alternately and intermittently, various small unit works are congested, and there is a problem that a work error or a work omission is likely to occur.

Therefore, in the conventional control panel manufacturing method as described above, the worker grasps only the work at hand and, after completion of the work, grasps the next work. Since the work at each location is advanced, the work is inefficient and work errors or omissions are apt to occur. If the work omissions occur, there is a problem that the delivery date is significantly delayed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a board manufacturing method for efficiently performing a board assembling operation.

Another object of the present invention is to provide a transport carriage for stably transporting a panel housing, articles, and the like necessary for assembling the panel.

It is another object of the present invention to provide a board manufacturing line for improving the efficiency of the board assembling work and reducing work errors and omissions.

[0009]

Means for Solving the Problems (1) In order to solve the above-mentioned problems, a control panel manufacturing method includes: an article receiving step of receiving and carrying in articles necessary for manufacturing a panel at an appropriate time from a supplier; An article stocking step of stocking articles brought in from the article receiving step in an order of each panel and unit assembly units that are pre-classified; and A marshalling step of paying out the goods for each of the unit assembly units, and a pre-assembly step of transporting the goods to be paid out in the marshalling step to a predetermined place and assembling a required assembly unit for each of the classified unit assembly units; And a general assembly process of incorporating various assembly units assembled in the pre-assembly process into the panel housing.

[0010] Therefore, by adopting the board manufacturing method having the above-described steps, in the article receiving step, the necessary goods for the board manufacturing are received and carried in from the ordering party in anticipation of the board manufacturing time, and the goods are stored in the article stocking step. Since the carried-in articles are stocked in the order of each board and the pre-sorted unit assembly unit, it is possible to stock while organizing and organizing each board.

[0011] In the marshalling process, by sequentially paying out each unit assembly unit of the corresponding board while taking into account the progress of the assembling work in the previous work assembling process, it is possible to avoid the congestion of the goods and to obtain supplies necessary for the work. Prepare in the right place. Further, in the pre-assembly process, the required assembly units are assembled for each of the classified unit assembly units, including cable processing, so that the parallel operation can be performed, and the work can be efficiently performed.

The pre-operation assembling step S6 includes assembling various units by performing in parallel the work for each unit assembling unit, including the preparation of tools, drawings, and supplies necessary for assembling the panel, and cable processing classified in advance. I do. In other words, by performing cable processing and unit assembly for each small unit operation that is appropriately divided without entering the panel housing and performing unit assembly as in the related art, work errors and work omissions are prevented. . After the completion of the pre-assembly step S6,
Based on the comprehensive assembling step S7, the assembly unit including the processed cable unit is used and assembled into the panel housing in a required order. Therefore, the problem that the work is congested can be solved. After the completion of the operation of the comprehensive assembling step S7, it is checked from a comprehensive viewpoint whether the articles are properly arranged and the cable wiring is properly performed.

Therefore, according to the above-described embodiment, the articles are stocked in a predetermined order while taking into account the assembly of the board, and marshalling is performed, for example, in accordance with the stock order. After assembling the cable unit including the cable processing for each unit assembly unit and unit assembly, it is finally incorporated into the panel housing. By eliminating the inconvenience of proceeding, the work can be proceeded efficiently without congestion of the work, and at the same time, work errors and omissions by the worker can be greatly reduced.

A wheel 3 that can be freely moved, a support mechanism 4 that is slidably housed on at least the opposite side of each side of the bogie main body 2 and that is pulled out to serve to prevent the bogie main body 2 from tipping over; A jack mechanism 5 attached to both side edges of one side of the main body 2 to prevent the carriage main body 2 from moving when stopped, and moving in directions (a) facing each other during transportation according to the size of the panel housing or assembly unit. A guide member 6 which is positioned while being moved, and a handle 7 which is attached to the upper surface of the bogie main body 2 on the opposite side of the jack mechanism 5 of the bogie main body 2 and allows the operator to move the bogie main body 2 forward or backward by hand. It is constituted by.

Although there are various types of mounting means for the guide member 6, for example, two long holes 8 are formed at a predetermined interval in a direction perpendicular to the guide member 6 of the bogie main body 2, and the guide member 6 is 6 is screwed from the outside of the support plate to a threaded backing plate (not shown) at the bottom of the bogie main body 2 through the elongated hole 8 and attached. If a thumb screw is used as the screw 9, a screw tightening tool is not required, and no special contact plate is provided at the bottom of the bogie main body 2.
If the screw tail end protrudes from the bottom side to the upper part through the long hole 8, the thumb screw can be loosened and the position of the guide member can be adjusted, and then the thumb screw can be tightened. It has the advantage of being easy to do.

Next, an example of transporting a panel housing or an assembly unit using the transport trolley 1 will be described with reference to FIGS.

In the initial state, the supporting mechanism 4 is housed in the bogie main body 2 as shown in FIG. In this state, for example, when a tall panel housing or the like is placed or transported, as shown in FIG.
And the support mechanism 4 is set to support the carriage body 2 from all directions when the carriage body 2 is inclined (FIG. 3A,
(B)). Thus, when the panel housing or the like is placed and transported to a predetermined location, the transport cart 1 can be prevented from tilting and falling.

Further, a jack mechanism 5 shown in FIG.
In the stored state, the carriage body 2 is in a movable state,
When the transport vehicle 1 stops at a certain position, the jack mechanism 5
Is operated so as to protrude to the floor, the bogie main body 2 can be securely fixed to the floor as shown in FIG. Therefore, in the above state, the bogie main body 2
Is fixed to the floor and the support mechanism 4 is also pulled out as described above, the carrier 1 is prevented from tipping over and unnecessary movement, and the carrying operation can proceed in a safe state.

By the way, in transporting a conventional housing or the like,
As shown in FIG. 4 (a), after placing the panel housing 10 on a general wheeled carrier 1A, the operator 11
Although the transport is performed while pressing the upper position at an appropriate height, the transport trolley 1A may run away or the casing 10 may fall over due to the force applied by the operator, and this is in a very dangerous state.

On the other hand, as shown in FIG. 4B, the carrier 1 used in the board manufacturing method according to the present invention is controlled by the guide member 6 in consideration of the center of gravity of the housing.
0 can be positioned in a stable state, and problems such as the balance of the carrier 1 being lost or the housing 10 being displaced due to the shift or inclination of the housing 10 during the transfer of the housing 10 can be avoided beforehand.

Further, as shown in FIG. 4B, a handle 7 for moving the carriage body 2 is attached,
Since the case 1 is conveyed while operating the handle 7, the case 10 is less likely to fall over, and the conveyance operation can be performed relatively easily and stably.

Therefore, according to the above-described embodiment, by using the carrier 1 having a structure as shown in FIG. 2, for example, an assembling unit including a panel housing of a tall heavy object or the like can be used. Even so, the operator can safely and quickly transport the housing and the like. Next, a basic configuration of a board manufacturing line according to the present invention will be described with reference to FIGS. FIG. 5 is a basic line configuration diagram, and FIG.
FIG. 6 is a detailed configuration diagram of a line illustrated in FIG. 5.

This board manufacturing line includes a product management unit 21 for managing various products necessary for manufacturing the board, a marshalling means 22 for inspecting and paying out necessary products in accordance with the manufacture of a specific board, and a board finalizing unit. A pre-work assembly line 23 for performing assembly work of various assembly units based on classification at a stage prior to assembly, and a comprehensive assembly line 24 for performing in-panel assembly of assembly units produced by the pre-work assembly line 23 And a check unit 25 for checking the final board assembled by the integrated assembly line 24.

Next, the above-described units 21 to 25 will be described in detail with reference to FIG.

The article management section 21 receives an order 26 for board products.
And a stock 29 for storing the received articles. That is, when receiving the order 26 for a board product, the article management unit 21 places an order 27 for an article necessary for manufacturing the board in accordance with the type of the board and required functions. The time of the goods reception 28 is determined by the lead time required for the goods order, that is, the period from the supply of the goods to the reception of the goods and the start of the assembly of the board product.
Instruct the supplier in advance when ordering supplies. Then, with the reception of the goods, the received goods are checked, the goods are carried in by the transport trolley, and stored in the stock 29 until the start of the panel assembly work.

When the assembly start time comes, the marshalling means 22 performs an inspection of the articles related to the board assembly and the created drawings, and as a preparatory operation, for example, setup, cable processing and cable processing for each unit assembly unit. When assembling the unit and the original unit, the payout of the necessary articles and drawings etc. is performed sequentially.

The pre-operation assembling line 23 is a line for performing an assembling operation at a pre-stage for each unit assembly unit which is classified in consideration of a work procedure which is predetermined in the panel assembly. , Setup 30, a cable unit including cable processing (hereinafter, referred to as cable processing) 31, a unit assembly 32, and the like.
Since the work of the unit assembly 32 including 1 is performed in parallel on each line, the work efficiency can be improved. Further, when the assembling work such as the cable processing 31 and the unit assembling 32 is completed, the checking is basically performed individually for each assembling unit, so that a work error or omission can be found immediately beforehand, and it is easy to make a correction. .

In the general assembly line 24, after assembling the assembly units including the cable units made by the previous operation assembly line 23 in a predetermined order, and connecting the assembly units, the work efficiency is low. In-panel work can be reduced to a minimum.

That is, conventionally, operations such as the setup 30, the cable processing 31, and the unit assembly 32 have been performed in a mixed state. However, in the production line of the present invention, the pre-operation assembly line 23 and the general assembly line 24 are While dividing,
By performing the cable processing 31 and the unit assembly 32 on a continuously flowing line as described later, the previous operation can be performed efficiently.

By constructing such a work procedure, it is possible to carry out collectively for each of the classified small unit works. Problems such as congestion due to the entry of work are eliminated, and work errors and omissions can be prevented.

Further, by performing the operations of the classified cable processing 31 and the unit assembling 32 in a continuous line other than the panel housing, the operation is greatly improved as compared with the conventional case where the operations are directly performed inside the housing. The work efficiency can be improved, and the work period can be greatly reduced.

The check section 25 is provided in the integrated assembly line 2
After assembling in the board by the method 4, a final check, for example, whether an appropriate article is used, whether a working cable is correctly connected between the units, and a predetermined comprehensive operation test are performed.

Next, an embodiment of each necessary component based on the above basic configuration will be described.

(First Embodiment) FIG. 7 shows an embodiment of a board manufacturing line according to the present invention, in particular, a product management section 2.
The configuration of the stock shelf 41 of one stock 29 will be described.

The stock shelves 41 are shelves for temporarily storing received articles, and have shelf numbers (1, 2, 3,...) 42 ₁ , 42 ₂ ,. In each row, a shelf number (A, B, C, or C) corresponding to each unit assembly unit classified as described with reference to FIG.
..) 43 ₁ ,..., 43 ₂ ,. That is, the shelf with the shelf number A stocks, for example, tools and drawings for the setup 30, the shelf with the shelf number B stocks with the cable processing 31, and the shelf with the shelf number C stocks with the unit assembly 32. Use as a shelf. As a result, it is possible to immediately take out a product necessary for assembly from a large number of products, and it is possible to efficiently manage products.

(Second Embodiment) FIGS. 8 to 11 illustrate an embodiment of a board production line according to the present invention, particularly an embodiment of a pre-work assembly line 23 and a general assembly line 24. FIG. FIG.

First, a plurality of roller mounts 50 shown in FIG. 8 are used for one or both of the previous assembly line 23 and the general assembly line 24.
They are arranged in a letter shape to form a U-shaped assembly line as shown in FIG.

The rack-equipped gantry 50 includes a flat pedestal 51 on which each article is placed and used for work, a plurality of rotatable rollers 52 mounted so as to be partially exposed from the surface of the flat pedestal 51, A leg 53 is attached to the bottom of the flat base 51 and has an electric or mechanical vertical drive mechanism.

As the mechanical vertical drive mechanism, for example, one having a structure as shown in FIGS. 9A and 9B is used.

FIG. 7A shows an X-shaped support 53b rotatably crossed between a flat base 51 and a floor support 53a, which is a part of the leg 53. Among them, FIG. Both ends of one support 53b are rotatably supported on a shaft, and the other end of the other support 53b on the floor side is a jack mechanism 5.
3c, the flat plate 51 can be slid in the illustrated (b) direction, and the upper end of the support 63b is slid along the long groove 53d along with the slide, thereby moving the flat table 51 up and down.

FIG. 6B shows X-shaped support members 53b and 53 using screw rods 53e having different screw thread directions.
By sliding the ends of b in opposite directions,
In this configuration, the flat base 51 is moved up and down. In addition, it can be electrically moved up and down using a motor, or can be moved up and down using air pressure, and is implemented using a conventionally well-known technique.

It is desirable to use the roller-mounted base 50 having a width slightly larger than the shoulder width of each worker from the viewpoint of ease of sharing work by one worker, carrying, folding storage, and the like. In the case where the equipment tables are installed on both sides of the user, those having a width dimension including the equipment tables are used. In the case of forming a U-shaped assembly line, it is necessary that the frame 50 with rollers to be installed in the bent portion of the U-shape has a substantially square shape. Therefore, the pedestal 5 with a plurality of sizes of rollers is required.
0 are combined and arranged in a U-shape to form a U-shaped assembly line.

Therefore, by attaching the up-down drive mechanism to the frame 50 with rollers as described above, the height can be adjusted to an appropriate value according to the size of the assembly units 55 and 56 as shown in FIG. Optimum height for work can be secured. In addition, when the gantry with rollers 50 moves up and down, the height is set in accordance with the height of the transport trolley when the units 55 and 56 are mounted on the trolley with rollers 50 at the start and completion of unit assembly and from the transport trolley. Then, the operation of replacing the unit can be performed smoothly.

FIG. 11 is a block diagram showing an example of a U-shaped assembly line 58 including the pre-operation assembly line 23, the general assembly line 24, and the line of the check section 25.

The U-shaped assembly line 58 is formed by arranging a plurality of pedestals 50 with rollers in a U-shape, and the flow direction of the assembly unit including the processing cable follows the direction of the arrow shown in the figure.

The U-shaped assembly line 58 is arranged from the upstream side in the order of, for example, cable processing 31, unit assembly 32, which is a plurality of small unit operations, integrated assembly line 24, and check unit 25. In these lines, for example, five workers 57 are arranged, and on one side or both sides of these workers, articles or the article mounting table 59 are placed. A tool stand 60 is provided.

For example, the five workers 57 basically carry out an assembly work only for their own work by standing work on a line moving from the left side to the right side in the figure. And
When the work is completed, the assembly unit including the processing cable moves rightward of the worker 57 and passes it to the next worker 57.

On the other hand, the tool stand 60 is disposed at a substantially central portion inside the U-shape, and five types of tools are prepared when five operators 57 always use the tool, and at least one tool is used when five operators 57 use less. Prepare an expression to realize a small space.

Therefore, by arranging the work as described above, the worker 57 can concentrate on the predetermined work without moving from the fixed position, and the work efficiency can be improved. Since the small unit work is carried out by each shared work, work errors and work omissions can be greatly reduced.

FIG. 3 is a diagram illustrating one processing example of a cable processing 31 and a cable test example after the completion of the cable processing in the pre-operation assembly line 23 in the board manufacturing line according to the present invention.

Conventionally, at the time of cable processing, the cable shield 71 and the core wire of the ground wire 72 are connected by melting the solder 73 as shown in FIG. The core wire 75 and the shield 71 are short-circuited, or the projection of the solder 73 damages the cable covering portion 74, causing insulation failure or causing trouble.

Therefore, the connection is made using a conductive metal sleeve 76 as shown in FIG. 13A, without using the solder 73 which causes a trouble. This conductive metal sleeve 76 has one or two confirmation windows 77 formed at a substantially central portion of the sleeve at a predetermined interval as shown in FIG.

In the conductive metal sleeve 76, the cable shield 71 and the core wire of the ground wire 72 are inserted from opposite sides of the sleeve 76, and the cable shield 71 and the ground wire 72 are respectively positioned at predetermined positions of the sleeve 76. After confirming through the confirmation window 77 that it has been inserted, the pressing portion 7 is pressed from the outside.
8 are formed to electrically connect the cable shield 71 and the core wire of the ground wire 72.

According to such an embodiment, the cable covering portion 74 does not melt due to heat, and the occurrence of insulation failure due to heat or protrusions can be prevented.

By the way, in the pre-work assembly line 23, FIG.
In addition to the cable processing shown in FIG. 3, a cable processing 31 for connecting various cables to each connector is also performed, but it is necessary to test the connection quality of the processed cable completed by this processing.

FIG. 14 is a view showing an automatic test apparatus for automatically testing the quality of the processed cable.

This automatic cable testing apparatus is designed to test by connecting a cable to be tested in which connectors 82a and 82b are connected to both ends of various cables 81.
This automatic cable tester includes connectors 82a, 8
2a, a pair of connectors 83a and 83b, a-side switches a1 to an and b-side switches b1 to bn at respective pins of the connectors 83a and 83b, and a-side switches a1 to a-side switch driving unit 84a that sequentially closes an and b-side switches b1 to bn
And the b-side switch drive section 84b and these drive sections 84a
, 84b in a predetermined order, and determines whether connection is good or not.

A controller is generally used as the determination processing main unit 85. The determination processing main unit 85 is connected to a power supply V and a resistor R for supplying a predetermined current between the a-side switches a1 to an and the b-side switches b1 to bn. A serial circuit 86, a reference data storage unit 87 for storing cable connection reference data, and a conduction determination unit 88 for determining conduction based on a voltage appearing across the resistor R
And a connection pass / fail determination unit 89 that determines connection success / failure based on the determination result.

Next, an example of the connection acceptance / rejection determination processing by the determination processing main unit 85 will be described with reference to FIG.

First, the pins of the paired connectors 83a and 83b are connected to both connectors 82a and 82b connected to the respective ends of the processed cable to be checked first.

In this state, when the operation of the determination processing main unit 85 starts, an initialization processing for setting 1 to the a-side counter memory and 1 to the b-side counter memory is performed (S1).
1, S12), after closing the a-side switch a1 via the a-side switch drive unit 84a (S13), and subsequently closing the b-side switch b1 via the b-side switch drive unit 84b (S14).

Then, the continuity judging section 88 judges whether a predetermined voltage is generated between the resistors R, that is, whether there is continuity or not (S15). It is determined whether or not the connection relationship between the switch a1 and the switch b1 is proper with reference to the cable connection reference data to be performed (S16). If the connection relationship is proper, the connection pass / fail determination unit 89 determines that the connection is acceptable (S16). S17).

When it is determined in step S15 that there is no continuity, it is similarly determined whether or not there is no continuity based on the cable connection reference data (S18). It is determined that there is a switch a1
-Store the switch b1 data and the unconnected determination result in an appropriate memory (S19). If there is no conduction and there is no connection relationship of switch a1 = switch b1, it is determined that the connection is normal, and the process proceeds to step S20. If the connection is established by the determination in step S16 but the connection relationship between the switches a1 and b1 is not present, the data of the misconnection is stored in an appropriate memory in addition to the side switch data and the b side switch data (S21). ).

As described above, the b-side switches b1 to bn
It is determined whether or not the determination processing has been completed for all of the above. If it has not been completed, +1 is incremented (S22), and the process returns to step S14 to repeat the same processing.

When all the b-side switches have been completed in step S20, the process proceeds to step S23, where it is determined whether or not the determination processing has been completed for all the a-side switches. If not completed, +1 is incremented. Thereafter (S24), the process returns to step S13 to repeat the same processing.

Thereafter, if all of the a-side and b-side switches are completed in step S23, it is determined whether or not there is an erroneous connection by referring to the contents stored in the memory (S25). It is determined whether or not there is (S
26) If any of them exist, switch data and cable connection NG are output (S27), and if all are normal, cable connection OK is output (S28).

Therefore, according to the above-described embodiment, the connection quality of the processed cable processed by the cable processing 31 is determined at the stage of the previous work, so that not only the connection relation of the cable can be automatically checked, but also After this test, appropriate processed cables can be passed through the integrated assembly line 24, and problems such as incorrect connection or no connection after assembling the panel housing can be greatly reduced. Even if an erroneous connection is found, it is possible to make the adjustment relatively easily.
