Description

The present invention relates to a work facility for manually applying a water blocking agent to a water blocking treatment portion at the tip of an electric wire.

When moisture comes into contact with the core wire joint of an electric wire, the moisture may permeate into the gap between the core wires due to the capillary phenomenon and adversely affect other places. Therefore, in the case of an in-vehicle electric wire or the like, it is widely practiced to perform a water stop treatment on a core wire joint or the like depending on the wiring location (see, for example, Patent Document 1).

As an example of water stop treatment, the water stop treatment part of the electric wire is immersed in a liquid tank of a water stop agent (instantaneous adhesive, etc.) in a low-viscosity liquid state, and after the immersion, the water stop agent is dried and cured to stop the water. It is common practice to obtain water performance. In an actual example, after immersion, a heat-shrinkable tube is placed on the relevant part and heated with a heater to dry and harden the waterproofing agent, and the shrinkage of the heat-shrinkable tube protects the waterproofing portion. There is.

By the way, when the operator manually grips the electric wire and immerses the water-stopping treatment portion at the tip of the electric wire in the liquid water-stopping agent in the water-stopping agent container, the water-stopping agent is applied to the upper edge of the container. It may scatter or adhere to such things.

For example, in an actual work site, the upper surface of a water blocking agent container is often covered with a lid for protecting the liquid level, and the tip of an electric wire is often immersed in the water blocking agent through a small work hole provided in the lid. .. In this case, the upper surface of the lid is used as a saucer that may be soiled by the water blocking agent, but there is a concern that the water blocking agent adhering to the upper surface of the lid may come into contact with the hands and the hands may become dirty. If your hands get dirty, the dirt may move to other work areas and spread throughout the work environment.

The present invention has been made in view of the above circumstances, and an object thereof is a work facility for applying a water blocking agent that can prevent contamination in a process of manually applying a water blocking agent to the tip of an electric wire. Is to provide.

In order to achieve the above-mentioned object, the work equipment for applying a water blocking agent according to the present invention is characterized by the following (1) to (4).
(1) Work equipment for process work in which a water blocking agent is applied to the water blocking agent by immersing the water blocking agent at the tip of the electric wire gripped by the operator's hand in the water blocking agent. And
A water-stopping agent container in which the water-stopping agent is housed and the water-stopping treatment portion at the tip of the electric wire gripped by the worker's hand is inserted from above.

Shutter and
A shutter opening / closing drive mechanism that drives the opening / closing of the shutter,
When the worker's hand, which is placed in front of the water blocking agent container when viewed from the worker and grips the electric wire, is moved toward the water blocking agent container, an on-signal is sent in response to the movement of the hand. The switch means that occurs and
A shutter drive control means that sends a drive signal to the shutter open / close drive mechanism in response to an on signal output from the switch means to move the shutter to the open position, and a shutter drive control means.
Equipped with
A work facility for applying a waterproofing agent to electric wires.

(2) The switch means has an operating member that is pushed down by the operator's hand, and a switch body that generates an on signal when the operating member is pushed down.

According to the work equipment having the configuration of (1) above, when the worker moves the tip of the electric wire grasped by his / her hand toward the water blocking agent container, the worker reacts to the movement of the hand and the water blocking agent container. The shutter that covered the upper surface of the door opens. Therefore, the water-stopping treatment portion at the tip of the electric wire is immersed in the water-stopping agent in a low-viscosity liquid state contained in the water-stopping agent container from above the opened water-stopping agent container to stop the water. A water blocking agent can be applied to the treated portion.
In addition, when the work of applying the water blocking agent is completed, the shutter closes and covers the upper surface of the water blocking agent container, so that it adheres to the upper edge of the water blocking agent container or the lid with a work hole on the top of the container. Your hands will not get dirty with the water-stopping agent. Also, if your hands get dirty, you may move the dirt around the work area, but since you can prevent your hands from getting dirty, that is no longer the case, and you can always keep your work environment clean. can.
The timing for closing the shutter can be set, for example, at a time after the switch means emits an ON signal and the shutter is opened, and then a time that can be considered to be the end of the immersion work is surely completed. Alternatively, it can be set at the time when the switch means switches from the on signal to the off signal.

According to the work equipment having the configuration of (2) above, the shutter is opened when the worker puts the hand holding the electric wire on the operating member. Therefore, the shutter is automatically opened in the flow of the coating work, and the operator can proceed with the work without being aware that the shutter is provided.

According to the work equipment configured in (3) above, the shutter is opened by lightly pushing down the switch bar by hand, and while bending the spring member as it is, the switch bar is moved further downward and lightly forward according to the movement of the hand. Can be defeated. Therefore, the hand can be placed on the switch bar to bend the flexible connecting member while the hand can be brought closer to the water blocking agent container, and the tip of the electric wire can be brought closer to the water blocking agent container. It can be soaked in the water without difficulty.

According to the work equipment having the configuration of (4) above, the sensor detects that the water-stopped portion at the tip of the electric wire is immersed in the water blocking agent, so that it is possible to know the presence or absence of immersion and the immersion time. .. Therefore, for example, it is possible to issue a warning when the sensor does not detect immersion even though the shutter is in the open state for a predetermined time, or to inform the operator when the immersion time has elapsed. As an example of the sensor, a pressure sensor can be provided at the bottom of the water blocking agent container, and when the tip of the electric wire is pressed against the bottom of the container, the pressure sensor can be set to detect it.

According to the present invention, since the shutter closes and covers the upper surface of the water blocking agent container when the water blocking agent is not applied, it adheres to the upper edge of the water blocking agent container or a lid with a work hole placed on the upper part of the container. Your hands will not get dirty with the water-stopping agent. Also, if your hands get dirty, you may move the dirt around the work area, but since you can prevent your hands from getting dirty, that is no longer the case, and you can always keep your work environment clean. can. Therefore, it is possible to prevent contamination in the process of manually applying the water blocking agent to the tip of the electric wire.

It is a perspective view which shows the state when it is brought close to a container 10 and the tips of electric wires W1 and W2 are immersed in the water blocking agent S in the water blocking agent container 10.

As shown in FIGS. 1 to 4, in this work equipment, the water stop treatment unit at the tip of the electric wires W1 and W2 held by the worker (the approximate position of the worker is indicated by H) with his / her own hand T. This is a work facility for process work in which the water blocking agent S is applied to the water blocking treatment portion R by immersing R in the water blocking agent S in a low-viscosity liquid state. Although the case where the core wire joints at the tips of the two electric wires W1 and W2 are immersed in the water blocking agent S is described here as an example, the number of electric wires is particularly limited as long as the operator can grasp the electric wires. Not done.

The work equipment for applying a water blocking agent according to the present embodiment includes a water blocking agent container 10, a shutter 20, a shutter opening / closing drive mechanism 21, a switch means 30, and a shutter drive control means (not shown). ing.

The water blocking agent container 10 is arranged so as to be located in front of the worker H, and the water blocking agent container 10 contains, for example, a water blocking agent (instantaneous adhesive or the like) S in a low-viscosity liquid state. There is. The upper surface of the water blocking agent container 10 is covered with a lid 11 having a small working hole 12 that functions as a saucer. From above the waterproofing agent container 10, the worker H inserts the water-stopping treatment portion R at the tips of the electric wires W1 and W2 gripped by his / her own hand T through the working hole 12 opened in the lid 11 to stop the water blocking agent H. Immerse in liquid agent S.

The shutter 20 is arranged above the water blocking agent container 10 at a slight interval, and is provided so as to slide open and close in the horizontal direction. As shown in FIGS. 1A and 2, the shutter 20 moves to a closed position (moves in the direction of arrow B) to cover the entire upper surface of the water blocking agent container 10 during the non-coating operation, and is shown in FIG. As shown in b) and FIGS. 3 and 4, the water blocking agent container 10 is provided so as to open the upper surface of the water blocking agent container 10 by moving to an open position (moving in the direction of arrow A) during the coating operation.

The shutter opening / closing drive mechanism 21 slides and drives the shutter 20 in the arrow A direction and the arrow B direction as described above.

The switch means 30 has a switch bar (operating member) 30A that is pushed down by the operator's hand T, and a switch body 32 that generates an on signal when the switch bar 30A is pushed down. That is, the switch means 30 generates an on signal in response to the movement of the worker's hand T holding the electric wires W1 and W2 when the hand T is moved toward the water blocking agent container 10. be.

The base end side of the switch bar 30A is connected to the switch body 32 via a flexible spring member 31, is supported in a cantilever shape, and extends substantially horizontally in the left-right direction when viewed from the operator. There is. Instead of the spring member 31, a flexible resin member or a metal member may be used as the connecting member. The switch bars 30A are provided in two stages side by side in the front-rear direction of the operator, and are located in front of the water blocking agent container 10 when viewed from the operator.

The shutter drive control means (not shown) sends a drive signal to the shutter open / close drive mechanism 21 in response to an on signal output from the switch means 30 to move the shutter 20 to the open position (operation of arrow A). Further, the shutter drive control means sends a drive signal to the shutter open / close drive mechanism 21 at a timing when it can be considered that the coating work is completed, and moves the shutter 20 to the closed position (operation of arrow B).

When the water blocking agent is applied to the water blocking agent R at the tips of the wires W1 and W2 using the above work equipment, as shown in FIG. 2, the operator uses his / her own hand T to apply the water blocking agent to the wires W1 and The W2 is gripped and the tips of the electric wires W1 and W2 (water stop treatment portion R) are moved toward the water stop agent container 10.

Then, in response to the movement of the hand, the shutter 20 covering the upper surface of the water blocking agent container 10 opens. Specifically, as shown in FIG. 3, when the hand T holding the electric wires W1 and W2 is brought close to the water blocking agent container 10, the hand T is placed on the switch bar 30A as the hand T moves. The bar 30A is pushed down by the pressure F from the hand T, and the shutter 20 opens in the direction of the arrow A.

Therefore, as shown in FIG. 4, from above the opened water blocking agent container 10, the water blocking agent S in a low-viscosity liquid state contained in the water blocking agent container 10 is formed through the working hole 12 of the lid 11. , The tip of the electric wire (water stop treatment portion R) can be immersed to apply the water stop agent S to the water stop treatment portion R. In this case, since the shutter 20 is automatically opened in the flow of the coating work, the work can be proceeded without being aware that the shutter 20 is provided.

Further, as shown in FIG. 4, the shutter 20 is opened by lightly pushing down the switch bar 30A with the hand T, and while bending the spring member 31 as it is, the switch bar 30A is further moved downward and lightly forward according to the movement of the hand. Can be defeated. Therefore, the hand T can be placed on the switch bar 30A, and the hand T can be further brought closer to the water blocking agent container 10 while bending the spring member 31, and the tips of the electric wires W1 and W2 (water stop treated portion R) can be brought closer. ) Can be reasonably immersed in the water blocking agent S in the water blocking agent container 10.

After the immersion, the tips of the electric wires W1 and W2 are lifted, the water-stopping treatment portion is covered with a heat-shrinkable tube (not shown), and the electric wires W1 and W2 are sent to the heating step.

As described above, in the work equipment for applying the water blocking agent according to the embodiment of the present invention, when the application work of the water blocking agent S is completed, the shutter 20 moves to the closed position and the water blocking agent container 10 is used. Cover the top surface. Therefore, the water-stopping agent adhering to the upper part of the water-stopping agent container 10 or the lid 11 with the work hole 12 placed on the upper part of the container 10 does not stain the hands. Also, if your hands get dirty, you may move the dirt around the work area, but since you can prevent your hands from getting dirty, that is no longer the case, and you can always keep your work environment clean. can.

The timing for closing the shutter 20 can be set, for example, at a time after the switch means 30 emits an ON signal and the shutter 20 is opened, and then a time that can be considered that the immersion work is surely completed has elapsed. Alternatively, it can be set at the time when the switch means 30 switches from the on signal to the off signal. However, in this case, it is premised that the switch means 30 continuously emits an ON signal during the coating operation.

Further, a sensor for detecting that the water-stopping treatment portion R at the tip of the electric wires W1 and W2 is immersed in the water-stopping agent S in the water-stopping agent container 10 is provided in or around the water-stopping agent container 10. You may. As an example of the sensor, a pressure sensor can be provided at the bottom of the water blocking agent container, and when the tip of the electric wire is pressed against the bottom of the container, the pressure sensor can be set to detect it.

Then, since the sensor detects that the water-stopping treatment portion R at the tip of the electric wires W1 and W2 is immersed in the water blocking agent S, it is possible to know the presence or absence of immersion and the immersion time. Therefore, for example, it is possible to issue a warning when the sensor does not detect immersion even though the shutter 20 is in the open state for a predetermined time, or to inform the operator when the immersion time has elapsed. ..

The switch means is not limited to a mechanical type as long as it operates according to the movement of the hand, and other types of switches such as a photoelectric type can also be used.
