Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for removing and collecting slag adhering to a welded part of a work.

[0002]

[Prior art]

 Conventionally, a worker uses a hammer to peel off the high-temperature slag that adheres to the welded part of a workpiece, and the separated slag is swept up with a broom and then collected in a slag box. As disclosed in JP-B-4-20713 and JP-A-60-25644.

In Japanese Patent Publication No. 4-20713, a brass roll is brought into contact with an outer peripheral welded portion of a steel pipe and rotated to separate slag and drop it into a recovery chute. In the one disclosed in Japanese Patent Laid-Open No. 60-25644, a grinder and a slag removing blade are provided at different positions, and a welded portion between the slag and the steel material adhering to the slag adhering portion is ground by a grinder to remove the slag. The removal blade scrapes off the slag that is lightly attached.

[0004]

[Problems to be solved by the device]

 However, the above-mentioned work by the worker is dangerous because the slag is hot, but the adhered slag is hard and requires a lot of time to remove it by hitting it with a hammer, and There is a problem that work efficiency is low due to fatigue, and any of the above-mentioned public reports has a problem that slag of a plurality of welds cannot be removed at the same time.

In view of this, the present invention has been made for the purpose of providing a slag removing / collecting apparatus capable of efficiently removing and recovering slag of a plurality of welded portions simultaneously in a short time without requiring human labor. It is a thing.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems of the prior art, the present invention attaches a removing tool to an endless running zone, and causes the removing tool to travel with a drive device and abut on the welding part of the work, thereby making the welding part of the work. It has a removing device that removes the slag that adheres, and a collecting discharge part that puts the slag that was removed by this removing device into the recovery part. Then, the discharge part may be provided with a gutter-shaped chute on the downstream side of the removing device.

[0007]

[Action]

 In the above device, the slag adhering to the welded part of the work is peeled off by the removing device which runs the removing tool mounted in the endless traveling zone, and the separated slag is thrown into the slag collecting part from the discharging part.

[0008]

【Example】

 An embodiment of the slag removing and collecting apparatus of the present invention will be described below with reference to FIGS. The slag removing and collecting apparatus 1 has a removing apparatus 2 and a discharging section 3, and the removing apparatus 2 includes a peeling section 4 and an elevating section 5.

In the peeling section 4, two sprockets 7 are pivotally supported on a rectangular frame 6 made of a channel material or the like, and a roller chain 8 as an endless running band is wound between these sprockets 7. Has been done. A plurality of flat plates 9 are fixed to the roller chain 8 at predetermined intervals, and a wire brush 10 constituting a removing tool is formed on a flat surface portion of the flat plates 9 in a direction orthogonal to the traveling direction. It is erected. Further, as shown in FIG. 3, a blade member 11 constituting a removing tool formed to have a length slightly shorter than the length of the wire brush 10 is fixed in parallel to one end of the flat plate 9. A motor 12 as a driving device is attached to one sprocket 7, and the sprocket 7 is rotated by driving the motor 12, and the wire brush 10 and the blade member provided on the flat plate 9 of the roller chain 8 are attached. As shown in FIG. 1, 11 travels in the direction of arrow A, which is orthogonal to the welding line of the work 13. Reference numeral 14 is a roller provided in the lower portion of the frame body 6, which is the most suitable for the tip of the wire brush 10 and the blade member 11 to separate the slag 15 when the roller 14 contacts the upper portion of the work 13. Is set to the position. Further, the work 13 welds the welded portion by the welder 16 and automatically moves to the left in FIG. 1 by a moving device (not shown).

The lifting unit 5 includes a rail 17, a carriage 18, and a hoisting device 19.

The rail 17 is made of I-shaped steel and is erected on the side of the work 13 in the traveling direction.

The dolly 18 includes a base plate 20, four main wheels 22 provided on the base plate 20, which come into contact with the rear side of the flange 21 of the rail 17 as shown in FIGS. 1 and 4, and the flange 21. It has two auxiliary wheels 23 that come into contact with the front side, and is vertically movable with the flange 21 in between. An attachment plate 24 is fixed to two end portions of the base plate 20 on the peeling portion 4 side, and a support shaft 25 is inserted between the attachment plates 24. A mounting plate 26 fixed to the end of the frame body 6 of the peeling section 4 is inserted into the support shaft 25, and the peeling section 4 moves and moves slightly in the vertical direction with respect to the elevating section 5. It is possible to move.

The hoisting device 19 has a motor 27 and a drum 28, and is fixed to a predetermined position of the rail 17. One end of a wire 29 wound around a drum 28 is fixed to the carriage 18 of the elevating unit 5, and the peeling unit 4 can be retracted from the work 13 by winding the wire 29 around the drum 28. You can do it.

The discharge part 3 is a gutter-shaped chute 30 which is inclined downward, and its upper end is fixed to the lower surface of the end of the frame 6 of the peeling part 4. The lower end is inserted into the upper portion of the slag box 31 and separated by the removing device 2 so that the slag 15 is dropped and collected through the chute 30 into the slag box 31 as a collecting section.

Next, the operation of the slag removing and collecting apparatus 1 will be described. First, the motor 27 of the hoisting device 19 is driven to rotate the drum 28 to lower the peeling unit 4 via the carriage 18. Then, when the roller 14 of the peeling section 4 contacts the upper surface of the work 13, the motor 27 is stopped.

Next, when the motor 12 of the peeling unit 4 is driven to move the wire brush 10 and the blade member 11 and the work 13 is moved, the slag 15 at the welded portion of the work 13 is first peeled by the blade member 11, and then, The wire brush 10 separates the slag 15 that was not separated by the blade member 11 and finishes the welded portion. Then, the stripped slag 15 on the work 13 is carried to the chute 30 side of the stripping section 4 by the wire brush 10 and dropped from the chute 30 into the slag box 31 to be collected.

[0017]

[Effect of device]

 As described above, according to the present invention, the slag removing and collecting device is equipped with a removing tool on the endless traveling zone, and while the removing tool is driven by the drive device, the removing tool is brought into contact with the welded part of the work. It has a removal device that separates the slag that adheres to the welded part, and a discharge part that puts the slag that was separated by the removal device into the recovery part.The slag that adheres to the welded part is automatically separated from the discharge part. Since the slag is put into the recovery unit, manual work is eliminated, and the slag can be automatically recovered without approaching the hot slag. Therefore, work safety is improved and work efficiency is improved. Further, since the removing tool is attached to the endless traveling zone, it is possible to remove and collect the slag at a plurality of positions at the same time, and further, there is an excellent effect that the working efficiency is improved.
