For example, the fuse cassette 10 has a vertical wall in front, rear, left and right and upper and lower end openings, and is long. It is formed in a rectangular cylindrical shape. A plurality of fuses 18 and 19 can be inserted into the fuse cassette 10 in an overlapping state from the upper end opening. In the fuse cassette 10, each of the fuses 18, 19 is movable downward by its own weight. As shown in FIG. 3, the front wall of the fuse cassette 10 (10 ₁ to 10 ₅ ) may be cut out so that the internal fuses 18 and 19 can be seen. Further, a hole for confirming a fuse may be provided in the cassette receiving portion 9.
[0025]
The lower rear wall of the fuse cassette 10 is provided with a hole or an opening through which the shafts 16 and 17 of the pair of upper and lower solenoids 11 and 12 are inserted. Each of the solenoids 11 and 12 excites an internal coil (not shown) to move the shafts 16 and 17 forward or backward against the force of a spring (not shown).
[0026]
3 and 4, blade fuses (having a pair of outwardly projecting tab-shaped terminals) 18 are accommodated in the two fuse cassettes 10 ₁ and 10 ₂ on the left side, and the three cassettes 10 ₃ to 10 ₅ on the left side.

The fuse receiving portion 14 is formed in a rectangular box shape, and an operator can get a fuse in the receiving portion 14 from the upper opening 21.
[0028]
As shown in FIG. 5 (a side view of the main part in FIG. 2), the upper and lower two solenoids 11 and 12 behind the cassette receiving portion 9 have shafts 16 and 17 that can advance and retreat in the front-rear direction, respectively. enters the fuse cassette 10 through the cassette receiving portion 9 the shaft 17 is advanced, positioned on the lower side of the lowermost fuse 19 ₁ of the fuse cassette 10, fuses 19 ₁ resting on the shaft 17 dropping of the fuses 19 ₁ is prevented Te. At this time, the shaft 16 of the upper solenoid 11 retreats and pushes the rear limit switch 22 to turn on (or off). Front end of the upper shaft 16 is retracted to a position not in contact with the fuse 19 ₂ in the fuse cassette. The switch 22 is for checking the presence or absence of a fuse.
[0029]
As shown in FIG. 6, the shaft 16 of the upper solenoid 11 moves forward and stops (holds) by pressing the _second fuse 192 from the bottom. In this state, the rear end of the upper shaft 16 still has the switch 22 turned on. Then by the shaft 17 of the lower solenoid 12 is retracted, the fuse 19 ₁ the lowermost is supplied to and falls fuse guide 13 via (2) the fuse receiving portion 14.
[0030]
When the fuse 19 in the fuse cassette runs out, the shaft 16 of the upper solenoid 11 largely advances (projects) into the fuse cassette by the force of the spring, the rear end of the shaft 16 is separated from the switch 22, and the switch 22 is turned off. (Or turned on). As a result, it is detected that the fuse 19 has run out. Since the upper and lower shafts 16, 17 will not be advanced together, the fuse 19 ₁ of the lowermost during switch-off has already dropped to the fuse receiving portion 14.
[0031]
When there is a fuse, the shaft 17 of the lower solenoid 12 moves forward from the state of FIG. 6 as shown in FIG. 5, the shaft 16 of the upper solenoid 11 retreats, and the fall of the fuse 19 is prevented. The required fuses 18 and 19 are supplied to the fuse receiving portion 14 one by one by repeating the operations of FIGS.
[0032]
In the control box 4 and the continuity checker 5 shown in FIG. 1, the product numbers and assembling order of the fuses 18 and 19 are registered in advance. The control box 4 and the continuity checker 5 are serially connected by a circuit 23, and the control box 4 is electrically connected to the solenoids 11 and 12 of the supply device main body 3 and the fuse presence / absence detection switch 22 by an I / O interface circuit 24. ing.
[0033]
The female terminals 26 (the mating terminals connected to the terminals of the fuses 18 and 19) of the respective fuse mounting portions 25 of the electric connection box (fuse block) 6 on the mounting base 7 are connected via electric wires (wire harness) 27. Connected to the circuit 28 of the continuity checker 5 by a connector 29. When a predetermined fuse is mounted on the fuse mounting portion 25 and the terminal of the fuse is connected to the terminal 26 on the fuse mounting portion side, a closed circuit is formed with the conduction checker 5 and the presence of conduction is detected.
[0034]
The operation flow will be described below with reference to FIG.
First, at the start of work (power-on), the part number of the fuse is acquired from the checker (31), and the part number of the registered data is compared with the part number of the checker (32). If the collation is NG, the process waits until the inspection is completed (33). If the verification is OK, it is determined whether or not the fuse supply point (the predetermined fuse mounting portion 25 of the electrical connection box 6) is open (whether or not a fuse is already mounted and the circuit is not closed) ( 34). This determination is made by collating with the data registered in the control box 4.
[0035]
If the point is open, one fuse is supplied according to the registration data (35). The supply of the fuse is performed by operating the solenoids 11 and 12 shown in FIGS. If the point is not open, it is determined whether or not it is the end point of the inspection (36).
[0036]
After supplying the fuse, the operator inserts a fuse into a predetermined fuse mounting portion of the electric connection box 6. The control box 4 determines whether a fuse has been inserted at a predetermined point (fuse mounting portion) of the electric connection box 6 (37). This judgment is made by confirming whether or not a predetermined circuit of the conduction checker 5 has been closed by inserting the fuse. If the fuse to be mounted on the electrical junction box 6 is, for example, the second fuse, it is checked whether both the first and second fuses are inserted and connected (mounted). If it is the third, check the insertion and connection state of the three fuses.
[0037]
If the insertion point is OK, it is checked with the switch 22 whether or not a fuse remains in the fuse cassette 10 (38). If the fuse remains, the process returns to the step (34) of determining whether or not the fuse supply point is open. If no fuse remains in the fuse cassette 10, the buzzer sounds and the lamp is turned on (39). The operator replaces the fuse cassette 10 with a new one and presses a button to extinguish the lamp (40), thereby returning to the step where the fuse remains (YES in 38).
[0038]
As described above, the control box 4 controls the supply of the fuse and the continuity check by the continuity checker 5 smoothly and reliably.
When the fuse in the fuse cassette 10 runs out, the last fuse in the fuse cassette 10 is correctly fitted to a predetermined position of the electrical junction box 6 and then the first time that the fuse has run out is notified (without sounding the buzzer). It is necessary to do so.
[0039]
That is, when the last fuse falls from the fuse cassette 10, it is possible to issue a warning that the fuse has run out. However, at that time, a warning is issued, and when the operator replaces the fuse cassette 10, the fuse receiving portion 15 There is a concern that the supplied fuse is left without being attached to the electric junction box 6. Therefore, in order to surely perform a series of operations (operations from the time when the fuse is supplied to the receiving portion 14 to the time when the fuse is mounted on the electrical junction box 6), a warning is issued after the fuse is mounted on the electrical junction box 6. To emit.
[0040]
When the second and subsequent fuses are mounted on the electrical junction box 6, it is necessary to check the conduction state of the previously mounted fuses (the fact that the fuses are securely mounted). Only when all of the fuses installed up to a certain point in time are OK for installation (conduction), the operation of mounting the next fuse can be started with the display of the continuity checker 5.
[0041]
In the above embodiment, the presence / absence of a fuse in the fuse cassette 10 is detected by the limit switch 22. However, a photoelectric tube or the like may be used instead of the limit switch 22 as the fuse presence / absence detecting means. Also, instead of the pair of upper and lower solenoids 11 and 12, it is also possible to use a pair of upper and lower air cylinders or other actuators as supply means.
[0042]
