Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves press-fitting a conductor pin into a conductor sleeve into which a core wire to be connected is inserted, and breaking the insulation coating of the core wire by the engagement between the sleeve and the pin, thereby electrically connecting the core wire. The present invention relates to a connector component remaining detection device that detects whether sleeves and pins of a connector remain so that they do not remain in the core wire splicing machine after the wire connecting work is completed in the core wire splicing machine.

With this type of core wire splicing machine, if the sleeve and pins of the connector remain in the machine after the work is completed, the sleeve and pin connector parts will move inside the machine during transportation, and these parts will not be in the correct position in the machine, so the work will be difficult. If the machine is restarted, the internal parts of the machine and the drive system will fail.
For this reason, when handling this wire splicing machine, it is required that the sleeve and pins remaining inside the machine be dry struck after the connection work is completed, and ejected from the machine before being stored and transported. As a result, there were many accidents that destroyed the machines.

SUMMARY OF THE INVENTION An object of the present invention is to provide a device for detecting remaining connector parts in a fiber splicing machine, which allows an operator to check if sleeves and pins remain inside the machine after the splicing work is completed. be.

Embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 schematically show an example of a fiber splicing machine 10 in which the connector remaining detection device of the present invention is used. The connecting machine stores the sleeve/pin combination 12 of the connector and connects the sprocket 1.
4, 14' having perforations meshing with the sprockets and striking means for striking out each one sleeve-pin combination 12 with a striking rod 18 from a belt 16 fed intermittently by these sprockets; 20
Separating means 2 separates the thus-knocked out sleeve/pin assembly 12 into a sleeve 12A and a pin 12B using a pin extraction rod 22.
4, these sleeves 12A and pins 12B are received and placed at the core connection position a and the release position b.
and a transfer means 26 for sequentially transferring.
The separating means 24 are, in the illustrated embodiment, the knocking means 2
0 and the transfer means 26
8, and the sleeve/pin combination hammered out by the punching means 20 is received within the sleeve receiving space 28a of this separation frame 28. The sleeve 12A is prevented from moving backward by the guide member 30 through which the pin 12B passes, so when the pin removal rod 22 moves forward, the pin 12B is pulled out while the sleeve 12A remains in the sleeve receiving space 28a and the guide member 30 and enters the pin receiving space 28b. As shown in FIG. 2, the punching means 20 is integrally formed with the punching rod 18 and has a pin receiving space 28b.
It has an auxiliary rod 18a opposite to the auxiliary rod 18a. Therefore,
Sleeve-pin combination 1 in separation frame 28
When the ejection means 20 is driven after the belt 16 has been separated and the belt 16 has advanced one bit, the next sleeve/pin combination 12 in the belt 16 is moved into the sleeve receiving space 28.
At the same time that the sleeve 12A and the pin 12B, which have already been separated, enter the transfer means 26.

The transfer means 26, as shown, consists of a rotor 32 which has receiving spaces 28a, 28b of the separating frame 28 at equal angular intervals on its circumference.
It has component receivers 32a and 32b corresponding to the parts. In the illustrated example, these parts receptacles are spaced 120 DEG apart and thus each has three parts receptacles. The rotor 32 rotates 120 degrees for each connection operation,
The sleeve 12A and pin 12B received from the separation means 24 reach the core connection position a and the discharge position b in sequence. At the core connection position a, there are two wires in the sleeve 12A.
After the core wires have been inserted, the pin 12B is press-fitted into the sleeve 12A by a driving rod (not shown) to connect these two core wires, and in this way the two core wires are connected at the discharge position b . A connector consisting of a sleeve and a pin with connected wires is ejected downwards.

When finishing the connection work with this fiber splicing machine, the belt 16 is removed from the fiber splicing machine 10.
A and pin 12B remain. Therefore belt 1
Even after removing the parts 6, it is necessary to empty the core wire connecting machine 10 to eject the parts inside the machine. In the first blank firing, the component at the core wire connection position moves to the receiving position c (position facing the separating means 24).
The parts located in the middle sleeve 12A are transferred to the core wire connection position a , but since the inner sleeve 12A of the sleeve 12A and the pin 12B separated within the separation frame 28 does not have the belt 16 on its side, the knockout means 20 does not operate. Even if the ejection rod 18 is short, the parts receiver 3 inside the rotor 32
Only the pin 12B enters the component receptacle 32b without being moved into the component receptacle 32b. In this way, the second and third blank shots are performed to release the last pin 12B. Note that one sleeve 12A remains within the separation frame 28, but this poses no problem because it does not shift its position even if the machine is subjected to vibration during transportation.

As shown in FIG.
A belt detection switch 44 detects that the sleeve 12A and the pin 12B remain in the transfer means 26, respectively.
and a pin detection switch 48, and an indicating means 50 for indicating to the operator that the sleeve 12A and pin 12B remain in the transfer means 26.

In the illustrated embodiment, the DC power supply 42 includes a commercial AC power supply 52 and a full-wave rectifier 5 that rectifies the current from the commercial AC power supply 52 via an isolation transformer 54.
6, and a battery 58 filled with the output of this full-wave rectifier. The full-wave rectifying means 56 and the battery 58 each have _one relay
The full-wave rectifier 56 is connected to the battery 58 via the charging control resistor R and the normally open contact _X1c of the relay _X1 . There is. The excitation coil of relay X ₁ is connected to the primary side of isolation transformer 54 and is therefore energized when the circuit is connected to commercial AC power supply 52 . Relay X ₁ contacts x1a, x1
b, x _1c constitute a changeover switch between the full-wave rectifier 56 and the battery 58.

Belt detection switch 44 may be, for example, a photoelectric switch disposed across belt 16 loaded in fiber splicing machine 10, as shown in FIG. It is open when in the splicer, but closes when the belt 16 is removed from the wire splicer 10.

Further, the sleeve detection switch 46 and the pin detection switch 48 are composed of micro switches as shown in FIGS. , 32b in an arc shape opposite to
0,62, pin 64 that holds these shoes,
66, the component receivers 32a, 32 via the operating arms 68, 70 attached to the upper ends of the pins 64, 66.
It is operated by the sleeve 12A and pin 12B inside b. The pins 64, 66 pass through cylindrical holders 74, 76 attached to the frame plate 72, and are constantly urged toward the rotor 32 by springs 78, 80 housed within the holders. Therefore, the sleeve 12A and the pin 1 are attached to the component receivers 32a and 32b.
When 2B is not present, the operating arms 68, 70 are pushed down, the micro switch opens, and the component receiver 32
When sleeve 12A and pin 12B are present at a and 32b, operating arms 68 and 70 are pushed up against springs 78 and 80, and the microswitch is closed.

The sleeve detection switch 46 and the pin detection switch 48 are connected in series to the output end _of the DC power supply 42 together with the excitation coil of the relay Relay X is connected in parallel to the excitation coil of ₂ .

The indicating means 50 may be a lamp, but is preferably an alarm such as a buzzer. When the detection switches 46 and 48 are closed, the relay _X2 is energized and lights up a pilot lamp (not shown) to indicate that work can begin.

Next, the operation of the connector remaining detection device will be described with reference to FIG. 7. The upper part of FIG. 7 shows the time when the work of the fiber splicing machine 10 starts, and the lower part shows the time when the work ends. First, when starting work, as shown in Figure 7A,
Since there are no connector parts inside the rotor 32 and the belt 16 is not loaded, the belt detection switch 44 is closed, but the sleeve detection switch 4
6 and pin detect switch 48 are open, so indicating means 50 is inactive. Then the belt 16
When the belt detection switch 44 is loaded, the belt detection switch 44 is opened (see FIG. 7B), and the connector component is ejected from the belt, and the sleeve 12A, which has remained in the separation frame 28, is transferred to the rotor 32. After that, the rotor 32 rotates 120 degrees and the sleeve detection switch 4
6 is closed (see Figure 7C). Meanwhile, the connector parts knocked out into the separation frame 28 during this time are separated into the sleeve 12A and the pin 12B by the pin extraction rod 22 of the separation means 24. In the second operation of the knockout means 20, a new connector part is knocked out from the belt 16 to the separation frame 28, and at the same time, the sleeve 12A and pin 12B that have been inside the separation frame 28 are transferred into the rotor 32. , the sleeve detection switch 46 and pin detection switch 48 are closed by the next rotation of the rotor 32 by one pitch (see FIG. 7D). At this time, the first sleeve is released from release position b . During the process of starting this work, at least one of the pin detection switch 48 and the belt detection switch 44 is open, so the instruction means 50 does not operate. Also, the driving position
When sleeve 12A and pin 12B are aligned at point a , both detection switches 46 and 48 close, so _relay
is energized, indicating that work can begin, and then the core wires can be connected.

On the other hand, when finishing the work, the belt 16 is first removed from the state shown in FIG. 7E (this is the same as the state shown in FIG. 7D), so the belt detection switch 44 is closed (see FIG. 7D). (see F), therefore, the indicating means 50 operates to warn that the parts remain in the rotor 32. Next, the machine is run several times to move the connector parts one by one to the ejection position b and eject them. During the blank run after removing the belt 16, the sleeve 12A moves into the sleeve receiving space 28 as described above.
Since only the pin 12B is moved to the rotor 32 while remaining in the pin 12B, when the rotor portion in which only the pin 12B is accommodated comes to the core connection position a , the sleeve detection switch 46 opens, but the pin detection switch 48
is closed (see FIG. 7G), therefore, the pin 12B is fired once again from the release position b , the detection switches 46 and 48 are both opened, and the operation of the indicating means 50 is stopped (the second (See Figure 7H). In this way, by performing blank firing until the operation of the indicating means 50 stops after the belt 16 is pulled out, it is possible to avoid the connector parts remaining in the rotor 32. When the work is finished and the power outlet is unplugged from the commercial AC power source, relay X ₁ will be demagnetized, so relay contact x _1a ,
Since the relay contact x _1c is opened and the relay contact x _1b is closed, the battery 58 is connected to the circuit, so that it is possible to reliably detect whether the connector component remains inside the rotor 32.

In the above embodiment, the separation means 24 is disposed between the knockout means 20 and the transfer means 26, but the connector parts are immediately transferred from the belt 16 into the rotor 32, and the connector parts are transferred from the belt 16 to the rotor 32. The present invention can be similarly applied to a wire splicing machine in which the separation means faces the transfer means 26 so as to separate the sleeve 12A and the pin 12B.

According to the present invention, as described above, since it is possible to reliably detect that the connector component remains in the transfer means, it is possible to avoid the connector component remaining in the transfer means by blank firing. Connector parts detection is used to prevent connector parts from shifting during transportation or storage of the machine, which will cause the machine to malfunction when the next machine is operated, and which has traditionally been used to detect sleeves and pins to indicate whether the machine is ready for operation. Since it is only necessary to combine the belt detection switch and the indicating means with the device, the structure is simple and can be provided economically.
