Description

Description: TECHNICAL FIELD The present invention relates to a traveling rail cleaning device in an automatic fusing device such as a gas fusing machine or a plasma fusing machine that cuts a work such as a steel plate by copying control or NC control. .

<Prior art> Generally, in an automatic fusing machine, a traveling rail is arranged along a work description table (a surface plate), a carriage is placed on the traveling rail so that the carriage can travel back and forth, and a torch carriage is orthogonal to the traveling rail. The torch carriage is equipped with a fusing torch such as a gas torch or a plasma torch, and the fusing torch is operated by NC control or scanning control, and installed on the work placement table ( Steel plate, etc.)
Is cut into a predetermined shape.

However, in this case, if the molten metal (slag) scattered during the fusing work adheres to the surface of the traveling rail, rattling occurs during traveling of the trolley, which deteriorates the quality of the cut surface.

Therefore, conventionally, there has been provided an apparatus in which a wiping tool or a brush is fixed to a dolly and the rail surface is cleaned as the dolly travels.

<Problems to be solved> In the above-mentioned conventional one, since the slag cleaning tool such as the wiping tool and the brush was fixed to the trolley, the slag removing tool moves while being in contact with the rail surface. There was a problem that the excluding tool was worn early and the slag removing effect could not be maintained for a long time, and the removed slag only moved on the rail surface and could not be removed outside the rail. .

The present invention has been made in view of such a point, and a rail that can efficiently remove slag from the rail surface that comes into contact with the wheels on the trolley side, and that can maintain the slag elimination effect for a long period of time. The purpose is to provide a cleaning tool.

<< Means for Solving the Problem >> In order to achieve the above-mentioned object, the present invention provides a location near the front and rear of a traveling wheel that is installed on a trolley that is reciprocally moved by being guided by a rail arranged along a work mounting table. A rail surface cleaning brush is rotatably arranged on the rail, and the cleaning brush is moved by interlocking the rotation shaft of the cleaning brush with an input gear that meshes with a rack fixed to the side wall of the traveling rail. It is characterized in that it is configured to be rotationally driven in conjunction with traveling.

<< Operation >> In the present invention, a rail surface cleaning brush is rotatably arranged at a position near the front and rear of a traveling wheel installed on a carriage that is guided by a rail and reciprocates, and a rotation shaft of the cleaning brush is disposed on the traveling rail. Since the cleaning brush is rotatably driven by being interlocked with the input gear that is in meshing engagement with the rack fixed to the side wall portion,
The slag adhering to the rail surface is wiped away by a cleaning brush driven in conjunction with the movement of the truck.

<Embodiment> The drawings show an embodiment of the present invention. FIG. 1 is a vertical cross-sectional view of essential parts, FIG. 2 is a schematic plan view of an automatic gas plasma fusing machine to which the present invention is applied, and FIG. It is a front view.

In this automatic gas fusing machine, a pair of left and right traveling rails (2) are arranged along opposite sides of a work placing table (1), and a carriage (3) is mounted on the traveling rail (2) so that it can travel back and forth. The torch carriage (4) is placed on the carriage (3) so that the torch carriage (4) can travel in a direction orthogonal to the traveling rail (2), and the fusing torch (5) is mounted on the torch carriage (4) so that it can be moved up and down. Is configured.

A control device (7) such as an operation panel (6) is arranged at the right end of the carriage (3), and the carriage (3) is moved along the traveling rail (2) at the left and right ends of the carriage (3). A traveling drive motor (8) for traveling and traveling wheels (9) are arranged.

A rack (10) is arranged along the longitudinal direction of the side wall of the traveling rail (2), and a traveling drive gear (11) rotatably driven by a traveling drive motor (8) is engaged with the rack 10). This allows the carriage (3) to move back and forth.

Reference numeral (12) is a slag removing unit for removing slag adhering to the upper surface of the traveling rail (2), and the slag removing unit (12) is a front portion of the front traveling wheel (9) and a rear traveling wheel (9). In the rear part of 9), they are arranged close to the traveling wheels (9). As shown in FIG. 1, the slag removing unit (12) is provided with a rack (1
The input gear (13) that engages with (0) and the rotary shaft (15) of the cleaning rotary brush (14) arranged facing the rail surface are interlockingly connected via the belt transmission mechanism (16). The cleaning rotary brush (14) is rotated in association with the traveling movement of the carriage (3). Thus input gear (1
3) and the rotating brush for cleaning (14) are connected via the belt transmission mechanism (16), the rotating brush (14) with respect to the rotation speed of the input gear (13) set by the moving speed of the carriage (3). It is possible to accelerate or decelerate the rotation speed of) to any rotation speed.

Further, as shown in FIG. 4, the slag removing unit (12) is supported on the carriage (3) in a swingable state in a horizontal plane, and the input gear (13) is a rack for traveling ( It is elastically urged by a spring (17) in the direction to engage with 10). As a result, even if the vehicle body of the trolley (3) expands due to temperature change, the slag eliminating unit (12) swings to absorb the displacement due to the expansion, and the input gear (13) The running rack (10) can maintain a constant occlusal state.

In the above embodiment, the input gear (13) and the cleaning brush (14)
Although the rotating shaft (15) is connected via the transmission mechanism (16), a gear transmission mechanism may be used instead of the belt transmission mechanism (16). Further, the rotation speed of the brush (14) may be changed and adjusted by changing the transmission ratio of the transmission mechanism.

In the rail cleaning device of the automatic fusing device configured as described above, the cleaning brush (14) of the slag eliminating unit (10) arranged on the truck rotates and adheres to the rail surface in association with the traveling of the truck (3). Since the slag that is running is swept out of the rail, there is no slag left on the rail, and the traveling wheels (9) guided by the rail roll smoothly without being affected by the slag. You can Therefore, the traveling wheels (9) do not travel while rattling, and the cutting performance can be maintained with high accuracy.

<< Effect >> In the present invention, the rail surface cleaning brush is rotatably arranged in the vicinity of the front and rear of the traveling wheel installed on the truck that is guided by the rail and reciprocates, and the cleaning brush is interlocked with the traveling traveling of the truck. Since it is configured to be driven to rotate,
The slag adhering to the rail surface can be swept out with a roller brush that is driven in conjunction with the movement of the truck. As a result, it is possible to prevent the bogie from rattling during its traveling due to the slag attached to the rail surface, so that the cutting performance can be improved.

Moreover, since the drive mechanism for the cleaning brush engages the input gear with the rack arranged for traveling by the dolly and transmits the rotation of the input gear to the cleaning brush, a power source for driving the cleaning brush is used. Since it is not necessary to separately prepare, the structure of the automatic fusing device can be simplified and the weight can be reduced.

Moreover, since the rotating brush removes the slag adhering to the running surface of the rail, it is possible to reduce the amount of wear compared to the one in which the brush or the wiping tool fixed to the truck contacts the rail surface, The rail surface can be cleaned well over a long period of time.
