[0006]

In the above-described conventional surface treatment apparatus for long material, which is horizontally suspended, since a plurality of long materials are held in an inclined state in the processing tank, the length of the long materials is reduced. L, when the inclination angle of the long material is θ, the long material cannot be immersed in the processing tank by the height of L sin θ,
There was a problem that the processing efficiency was poor.

An object of the present invention is to provide an apparatus for treating a surface of a long material, which is excellent in processing efficiency, and which is of a horizontal suspension type.

[0008]

According to the present invention, there is provided a surface treatment apparatus for a long material of a horizontal suspension type according to the present invention, wherein a processing frame in which a plurality of long materials are stacked in an interdigital shape, and each long material is immersed in a processing tank. Between the immersion position and the draining position at which each long material is taken out of the processing tank and drained from the processing tank. in continuous material surface treatment apparatus, one for each cylinder of the lifting body, the speed for driving the
Controllable inverter control motor is provided, immersion
When in the pickled position, the left and right elevating bodies located at the same level will rotate the left motor (21) and the right motor in rotation.
When at the draining position due to the difference in speed
And it is characterized in that it is adapted to be be positioned at different levels in the.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. In the following description, the left and right in FIG. 1 are referred to as left and right, and the direction perpendicular to the plane of FIG.

FIG. 1 shows an apparatus for treating the surface of a long material of a horizontal suspension type according to the present invention. The processing frame (2) to be loaded, the immersion position where the long material (A) was immersed in the processing tank (4), and the liquid draining position where the long material (A) was discharged from the processing tank (4). And a pair of left and right buckets (elevators) (15) and (16) that move up and down while supporting the processing frame (2).

The processing frame (2) is of a known type called a frame stop system, and is composed of a horizontal member (5) extending in the left-right direction and a pair of left and right vertical members (6) (7) suspended from the horizontal member. Become. Each vertical member
Each of (6) and (7) is provided with a plurality of shelves, and the long material (A) can be stacked on the processing frame (2) in a plurality of stages in a horizontal state or an inclined state.

Each of the buckets (15) (1)
A pair of left and right vertical guide rails (17) and (18) for guiding 6),
And a pair of left and right electric motors (21) and (22). The wire (19) hanging the left bucket (15) is connected to the left motor (21)
A wire (20) wound around a winding section (23) provided on the rotating shaft of the right motor (22) is wound around a winding section (23) provided on the rotating shaft of the right electric motor (22). It is wound around the Toribu (24). Each of the electric motors (21) and (22) is an AC motor driven by an inverter, whereby the speed of each of the buckets (15) and (16) is independently controlled.

As shown in detail in FIG. 2, the left bucket (1
5) is a rectangular parallelepiped shape having an open upper end and a right end. The bottom wall portion supports the lower surface of the left end of the cross member (5) of the processing frame (2) and moves up and down. The left guide rail (17) has a U-shaped cross section that opens rightward and has an inwardly projecting edge. A block (25) is fixed to a left wall of the left bucket (15), and a left wire (1) is attached to an upper end surface of the block (25).
The lower end of 9) is fixed, and near the upper end of the block (25), a pair of front and rear small rollers (26) and (26) that rotate around the front and rear horizontal axis are attached. A large roller (27) that rotates around a horizontal axis is attached. Both the front and rear small rollers (26) (26) and the large roller (27) are fitted in the guide rails (17), and the bucket (15)
Can smoothly move up and down by supporting the processing frame (2) on which a large number of long materials (A) are stacked.

[0014] The long material surface treatment apparatus described above, the long material
When processing (A), the long material (A) is stacked horizontally on the processing frame (2), and the buckets (15) and (16) are moved right and left as shown by solid lines in FIG. At the same level, and at the time of draining, at different levels on the left and right as indicated by the dashed line in FIG. Therefore, at the time of processing, as shown by the solid line in FIG. 1, each long material (A) is kept horizontal, and a plurality of long materials (A) are immersed in the processing tank (4) so as not to waste. be able to. In order to position the left and right elevating bodies (15) and (16) at the same level during processing at different levels at the time of draining, for example, the left and right electric motors (21) and (22) are simultaneously operated and each bucket (15) ( 16) and raise the left motor (2
The rotation speed of 1) is made faster than the rotation speed of the right electric motor (22), and the left and right electric motors (21) and (22) are stopped at the same time. As a result, each bucket (15) (16) stops at a different level,
(A) is in an inclined state, and the liquid is surely drained.

The rotation speed of each of the motors (21) and (22) can be freely and independently changed independently, whereby the best conditions can be obtained in accordance with the size of the long material (A) to be processed. Can be selected. The rotation speeds of the electric motors (21) and (22) are kept equal, and the buckets (15) and (16) can be kept in a horizontal state during processing and in an inclined state during drainage by shifting the operation timing. It can be made to be. Further, stoppers for regulating the lowermost position and the uppermost position of each of the buckets (15) and (16) may be provided. Thus, the buckets (15) and (16) can be moved up and down more reliably.

[0016]

According to the horizontally suspended long material surface treatment apparatus of the present invention, each lifting body is separately driven by the electric motor, and the left and right lifting bodies are at the same level when in the immersion position. When it is in the cutting position, it is located at a different level, so that during processing, the long material can be immersed in the processing tank so that no waste occurs, and when the liquid is drained, the long material is inclined. Liquid can be drained reliably.
