The operator inputs a predetermined pattern number (08 in the figure) to the DIP switch 21 according to the product number of the relay block 6 into which the relay is inserted, and presses the product number setting button 19. The product number setting and the like are performed via the control box 11.
[0028]
In FIG. 1, the slit plate 8 is located on the upper surface side of the detection box 9 and has a slit-like insertion hole 22 for a male tab-like terminal (not shown) of each relay as shown in FIG. A leaf spring-like switch (detecting means) 23 for confirming the insertion of the relay is provided directly below the switch. The switch 23, its contacts, the lead wires, bus bars, and the like (not shown) that follow them are housed inside the detection box 9 (FIG. 1).
[0029]
Each insertion hole 22 of the slit plate 8 is arranged according to the position and direction of the terminal of each relay 4. The size of the insertion hole 22 is slightly larger than the thickness and width of the relay terminal. The switch 23 is raised obliquely upward and is pressed at the tip of a required terminal of the relay 4. Whether or not the predetermined relay 4 is inserted into a predetermined position of the slit plate 8 is defined by the position and direction of each insertion hole 22. The terminal of each relay 4 pushes each switch 23 downward, and the switch 23 comes into contact with the lower contact, so that the lead wire (circuit) of the switch 23 forms a closed circuit, and the relay 4 is inserted. Is detected.
[0030]
Insertion hole 22 with 4 pole relay and 5 pole relay₁Are used in common, and the terminal of the four-pole relay is the insertion hole 22 at the center of the three parallel insertion holes.₂Switch 23 just below₂By making no contact, it is possible to distinguish it from the terminals of a five-pole relay.

The small relay and the large relay have terminals with the same arrangement and shape, and differ only in the size of the case._ThreeIs inserted in the insertion hole of the same, and reference numeral 23_ThreeAre commonly detected by the switches. The small and large relays are denoted by reference numeral 28 of the guide plate 10 in FIG._ThreeIt is inserted at the position of the insertion hole. The slit plate 8 is provided with insertion holes 26 for four leg portions 25 (FIG. 5) of the set plate 5 described later.
[0032]
In this embodiment, a color detection sensor 27 including a light emitting diode (light emitting portion) for identifying a special relay color and a light receiving portion thereof is provided at the other end of the slit plate 8. The color of the relay 4 is mainly black, but a special relay (for operating important components) is blue, for example, and the blue light from the light emitting unit is irradiated to the relay, and the reflected light is received by the light receiving unit. Thus, the color difference of the relay 4 is detected.
[0033]
A synthetic resin guide plate 10 is installed above the slit plate 8, and the guide plate 10 guides the insertion of each relay 4. As shown in FIG. 4A, the guide plate 10 has a plurality of types of insertion holes 28 having shapes, sizes, and positions corresponding to the arrangement of the relays 4. The size of the insertion hole 28 is slightly larger than the outer width dimension of the relay 4 in the XY direction. A pattern number 29 (No. 08 in this embodiment) corresponding to the product number of the relay block 6 is entered on the surface of the guide plate 10. The guide plate 10 is a single flat plate as shown in FIG.
[0034]
A predetermined insertion hole 28 of the guide plate 10 corresponding to a special relay such as blue.₁An identification color 30 of the same color (blue) as that of the relay is provided in a frame shape. Thereby, an operator can set to a predetermined place reliably by visual observation without mistaken for the other relay 4 by a special relay. After setting, the special relay is double checked by the color detection sensor 27 of the slit plate 8 (FIG. 3).
[0035]
4A, reference numeral 31 denotes a positioning hole for allowing the head 32 of the fixing screw of the slit plate 8 to enter, and 33 denotes an insertion hole for a leg 25 of the set plate 5 described later. With the guide plate 10 set on the slit plate 8, the insertion holes 22 of the slit plate 8 are located below the insertion holes 28 of the guide plate 10. At least five types of relays are set on the guide plate 10 shown in FIG.
[0036]
As shown in FIG. 5A, the set plate 5 has relay holding holes 51 having the same number and position as the insertion holes 28 of the guide plate 10 and the same shape. A rubber holding member 34 is provided on the inner surface of the holding hole 51 in two directions, front and rear, right and left, or intersecting. The dimension between the pair of opposing holding members 34 is set slightly smaller than the outer width of the relay 4. The relay 4 is clamped and fixed by the pair of holding members 34. Since the holding hole 51 has the same shape as the insertion hole 28 of the guide plate 10, erroneous assembly (erroneous setting) of the relay 4 is reliably prevented.
[0037]
At one side end of the set plate 5, a pin portion (detected portion) 35 composed of a short machine screw or the like for pressing the two switches 24 on one side end of the slit plate 8 (FIG. 3) faces downward. Projected. One having two pin portions 35 is a set plate for a large relay, and one has a set plate (not shown) for a small relay. 51 for small and large relays₁It is inserted at the position of the holding hole. Holding hole 51 with small and large relays₁The shape is different. The presence / absence and quality determination and display by the switches 23 and 24 and the sensor 27 are performed via the control unit 11 (FIG. 1).
[0038]
The set plate 5 has four leg portions (long pin portions) 25 protruding vertically downward. Each leg portion 25 is inserted into each of the holes 33 and 26 of the guide plate 10 and the slit plate 8, and positions the set plate 5, the guide plate 10 and the slit plate 8 relative to each other. It is preferable to provide grip portions (not shown) for handling on both side ends of the set plate 5.
[0039]
The operation method (relay insertion method) of the set machine 2 will be described below.
The operator sets the product number of the relay block 6 to be used as described above, and sets the guide plate 10 corresponding to the product number on the slit plate 8 of the detection table 9 placed on the table 7.
[0040]
The operator hooks the wire harness (a plurality of electric wires) on the protruding rod 36 on the near side of the press machine 3 in FIG. 1 so as not to obstruct the work, and the relay block 6 following the wire harness is placed on the set base 13. And fixed with a locking member (not shown).
[0041]
Next, the operator inserts each relay 4 one by one into a predetermined insertion hole 28 of the guide plate 10. If the relay 4 is to be inserted into the insertion hole 28 other than the predetermined one of the guide plate 10, the relay 4 and the insertion hole 28 are different in shape, and the insertion hole 22 of the slit plate 8 below the guide plate 10 is not inserted. And the position of the terminal of the relay 4 do not match, double insertion is prevented. The relay terminal that has entered the insertion hole 22 of the slit plate 8 elastically contacts the lower switch 23, and the switch 23 electrically detects that the terminal of the relay 4 has been inserted. When the insertion of all the relays 4 is completed, the product number setting button (confirmation lamp) 19 is turned on to notify the operator of the insertion result OK. This operation is also performed via the control box 11.
[0042]
Next, the operator sets the set plate 5 on the guide plate 10, and the upper half of the relay 4 protruding from the guide plate 10 is inserted and held in each holding hole 51 of the set plate 5. At the same time, the pin portion 35 of the set plate 5 pushes the switch 24 of the slit plate 8 to turn it on, and the buzzer 22 (FIG. 2) sounds, and it is detected that the set plate 5 has been set with a normal stroke. Which of the small relay and large relay set plates 5 is used is discriminated. This operation is also performed via the control box 11. Each relay 4 is held in the middle in the height direction by the elastic member 34 of the set plate 5, and the upper half of each relay 4 is positioned to protrude upward from the set plate 5.
[0043]
  The operator lifts the set plate 5 together with the relay, removes it from the guide plate 10, and sets it on the relay block 6 of the press 3 (FIG. 1). Each relay 4 is transferred from the guide plate 10 or the slit plate 8 to the set plate 5, and each relay 4 is set on the relay block 6 integrally with the set plate 5. A switch (not shown) is turned on simultaneously with setting of the set plate 5, and the press machine3The start button 37 lights up.
[0044]
Hereinafter, the press machine 3 will be described in detail.
As shown in FIGS. 1 and 6, the relay block 6 is set and fixed along the positioning wall 38 on the setting table 13. Reference numeral 39 is a sensor for detecting the presence or absence of a relay block, and 40 is a cylinder for fixing the set plate. The leg portion 25 of the set plate 5 is inserted into the relay block 6. The set base 13 of the press machine 3 is supported horizontally by the leg portion 52 (FIG. 1). Start buttons 37 are arranged on both sides of the set table 13. A phototube area sensor 41 (FIG. 6) is provided on the back surface of the start button 37. When an operator's hand enters the space inside the press 2 from the start button 37, the area sensor 41 is provided. Operates and press operation stops.
[0045]
Two vertical cylinders 14 and 15 are fixed to an apparatus frame 18 on the set table 13, a rod 14a of one cylinder 14 is connected and fixed to a horizontal press plate 16, and a rod 15b of the other cylinder 15 is a press plate. 16 is free to face. The press plate 16 is connected to vertical slide bars 42 on both sides, a proximity sensor 43 is provided on the frame 18, and a detected portion 44 for the proximity sensor 43 is provided on the slide bar 42 so as to protrude.
[0046]
In the frame 18, three display lamps (display units) 45 to 47 that are turned on according to the stroke of the press plate 16 are arranged vertically. Plunger switches 17 corresponding to the respective relays 4 protrude from the press plate 16. The plunger switch 17 has a slide pin 17a that is projected and biased downward by a coil spring, and the switch is turned on while the slide pin 17a slides in the retracting direction.
[0047]
Below, the relay insertion method using the press machine 3 is demonstrated.
When the operator sets the set plate 5 integrated with the relay 4 on the relay block 6 and then presses the start button 37, the rod 14a of the first cylinder 14 extends to lower the press plate 16 and lower the pressing force. Then, each relay 4 held by the set plate 5 is pressed downward toward the relay block 6 to be temporarily inserted (initially inserted) into each relay mounting portion 48 (FIG. 6) of the relay block 6. The relay mounting portion 48 is configured to be surrounded by, for example, a frame-like wall portion, and a female terminal 49 for relay connection is located on the bottom side of the relay mounting portion 48.
[0048]
At the time of this temporary insertion, the proximity sensor 43 (FIG. 6) is turned on in proximity to the detected portion 44, the lowering of the press plate 16 is temporarily stopped, and the first detection lamp 45 is lit. By this temporary insertion operation, if the relay 4 is set in the wrong direction or obliquely, or the relay 4 is caught by the relay mounting portion 48, the press plate 16 does not reach the proper temporary insertion position. The first lamp 45 is not lit, an abnormal insertion of the relay 4 is detected, and the pressure of the cylinder 14 is released by the operation of the switching valve. Thereby, breakage of the relay 4 and deformation of the relay block 6 are prevented. By the temporary insertion, the relay 4 is lowered in the relay mounting portion 48 to a position where the tab-shaped terminal substantially contacts the inlet of the female terminal 49 in the relay block 6.
[0049]
After the first lamp 45 is turned on (temporary insertion is OK), each plunger switch 17 detects the presence or absence of each relay 4 while contacting each relay 4. When it is detected that there is no relay, the pressure of the cylinder 14 is released by the operation of the switching valve. When all the relays are detected, the second lamp 46 is turned on. In this way, since the presence or absence of the relay 4 is detected by the plunger switch 17 at the time of temporary insertion of only the first cylinder 14 with low force, even if the relay 4 is temporarily inserted, the relay mounting portion 48 of the relay block 6 from the set plate 5 is detected. Even if it falls into the inside due to its own weight, the presence or absence of the relay 4 can be reliably detected by the protruding operation by the spring bias of the plunger switch 17.
[0050]
Next, the rod 15a of the second cylinder 15 extends to press the press plate 16 together with the first cylinder 14 with a strong force, and each relay 4 is fully inserted into each mounting portion 48 of the relay block 6 (completely Insert). By this insertion, the terminal of the relay 4 is completely inserted and connected to the terminal in the relay block 6. The proximity sensor 43 is removed from the detected portion 44 and turned off, and the third lamp 47 is lit to notify the completion of insertion. Both cylinders 14 and 15 are compressed and lifted together with the press plate 16 to return to the original position. The operator removes the set plate 5, removes the relay block 6 from the press machine 3, sets the next relay block 6 in the press machine 3, and repeats the same operation as described above.
[0051]
In the above embodiment, the two cylinders 14 and 15 are used. However, the setting is made by using a valve or the like so that only one cylinder performs temporary insertion of weak pressure and main insertion of strong pressure. It is also possible. Further, instead of the proximity sensor 43 that detects the stroke of the cylinder, that is, the position of the press plate 16, another sensor or switch may be used.
[0052]
The set plate 5 is used in common except for large and small relays, and the guide plate 10 is used separately. However, the guide plate 10 has a relay holding mechanism (for example, holding) similar to the set plate 5. It is also possible to provide a set plate by providing rubber or the like. In this case, the set plate 5 is eliminated and the structure of the set machine 2 is simplified. The set plate shown in claim 1 of the claims includes the set plate in this case.
[0053]
