Description

  The present invention relates to a strip edge wiper device applicable to a ringer roller, a tension leveler, etc. of a steel strip processing line.

As a first example of this type of apparatus, in order to remove water and the like at the edge of the steel plate, a plurality of air nozzles are provided so as to hit each edge depending on the width of the steel plate. And when it was desired to retreat the nozzle due to an abnormal shape of the plate, it was lifted with an air cylinder or the like.

As a second example of this type of device, the device disclosed in Patent Document 1 is as follows. That is,
As shown in FIG. 5, when the two rolls are made of elastic urethane rubber and the strip 1 is passed between the rolls, the nozzle 8 seals the liquid coming out of the triangular gap 7 generated at the long end of the strip. Is provided. The nozzle injects high-pressure air into the gap 7. The motor 9 is rotated through the chain 12 so that the nozzle position can be moved, and the nozzle mounted on the screw rod is moved.

  As a third example, the one in Patent Document 2 is as follows. In other words, air headers are provided above and below the strip, and these are movable in the plate width direction, and a device for detecting the position of the air header is provided.

  However, any of these conventional devices requires a large nozzle drive device. In the second and third examples, since the nozzle is moved in the strip width direction, a space is required on both sides of the strip, and the operator cannot approach that portion. Thus, since the nozzle is moved linearly, a large space is required in principle, and the stroke of the drive air cylinder is also long.

  An object of the present invention is to solve the above-mentioned problems and to provide a device that can easily retract an air nozzle when necessary and does not use a driving device such as an air cylinder.

The first problem-solving means of the present invention is to remove water or the like adhering to the edge portion of the strip of the steel strip processing line, and is disposed around the horizontal axis along the strip width direction with an interval above the strip. A rectangular frame in plan view that is rotatably supported, an operation handle that rotates the frame, a means that allows the frame to be rotated and fixed, and a frame that is fixed to the upper side of the frame and extends in the strip width direction. A plurality of air jet pipes extending downward from the air header along the strip length direction and provided in pairs in the strip width direction, and an air nozzle attached to the tip of the jet pipe. That is.

  According to a second problem solving means of the present invention, in addition to the first problem solving means, in the means for rotating and fixing the frame, the second support column is provided with an arc-shaped slit, and the hole provided in the operation handle and the slit are provided. The bolts are passed through and fastened with nuts, and the rotation range of the frame can be changed steplessly.

  According to the first problem solving means of the present invention, it is possible to provide a device that can easily retract the air nozzle when necessary and does not use a driving device such as an air cylinder. In addition to the effects of the first problem solving means, the rotation range of the frame can be changed steplessly by the second problem solving means of the present invention.

It is a principal part top view of one Example of this invention. It is X2-X2 sectional drawing of FIG. It is a principal part perspective view of FIG. It is a principal part perspective view of the other Example. It is a side view of a conventional device.

An embodiment of the present invention will be described below with reference to the drawings.
1 and 2, the present invention removes water and the like attached to the edge of the strip S of the steel strip processing line. The main points are a main frame 1 having a rectangular shape in a plan view supported rotatably around a horizontal axis 3 along the strip width direction with a space above the strip, and an operation handle 11 for rotating the frame. And means 12 for enabling rotation and fixing of the frame, an air header 5 fixed to the upper side of the frame and extending in the strip width direction, and extending downward from the air header along the strip length direction, In addition, a plurality of pairs of air injection pipes 6 are provided in the strip width direction, and an air nozzle 7 is attached to the tip of the injection pipe.

  The main frame 1 having a rectangular shape in plan view has its extended surface substantially parallel to the upper surface of the strip, and two opposite sides (front and rear sides) of the rectangle are parallel to both ends (edges) of the strip. A horizontal shaft 3 is provided extending in the strip width direction from the center of two opposite sides (front and rear sides) of the frame, and this horizontal shaft is rotatable on the upper surface of the first support column 8 standing from the floor via a bearing. .

  A gate-shaped sub-frame 2 is erected on the upper side of the front side of the two opposite sides (front and rear sides) of the main frame 1, and the handle shaft 10 extends forward from the center of this upper side via the intermediate piece 4 in the plate width direction. A thin plate-like operation handle 11 is provided at the tip. As a result, when the handle is gripped with both hands and rotated clockwise and counterclockwise, the main frame 1 swings around the horizontal axis.

  The second support column 9 is erected from the floor close to the operation handle 11, and is provided with two positioning holes 9a. And this hole and the hole provided in the handle | steering_wheel are match | combined and it fastens with the volt | bolt 12. FIG.

  In the above, nozzle systems (represented by a, b, and c, respectively) are divided corresponding to the large, medium, and small plate widths. PBL (push button / lamp), “Large”, “Medium” and “Small” operation displays are provided on the “Edge Wiper Operation Panel” on the machine side. Air is sent from the nozzle of the system corresponding to each PBL. For this reason, each system is provided with a solenoid valve and a relay circuit for its operation. As a countermeasure against defective solenoid valves, a bypass is provided for each solenoid valve. Install valves and pressure systems in each system.

  The operating state will be described above. As shown in FIGS. 1 and 2, compressed air is supplied to the nozzle 7c, the injection pipe 6c, and the header 5c corresponding to the plate width “small”, as shown by the solid line, and the water adhering to the edge portion of the strip. Blow away and remove. When the plate width changes, the compressed air is supplied to the nozzle, the injection pipe, and the header corresponding thereto.

  Now, when the nozzle 7 is separated from the strip, first stop the air supply, then loosen and remove the bolt 12 of the operation handle 11, hold the handle with both hands and turn it slightly to the left, both holes of the handle and the second support column 9 And fasten with bolts (FIG. 3). As a result, the main frame 1 rotates slightly to the left together with the air system including the nozzles, and the nozzles are separated from the strip as indicated by the dotted lines in FIG.

  FIG. 4 shows another embodiment. As a means for rotating and fixing the operation handle 11, an arc-shaped slit 9 a is provided in the second support column 9, the hole of the handle is aligned with the slit, the bolt 12 is passed, and the wing nut 13 is fastened. Thereby, it becomes possible to change the rotation range of the handle only by loosening the wing nut without removing the bolts one by one.

  The present invention is not limited to the examples and embodiments described above, and includes various modifications without departing from the scope and scope of the claims.

  The present invention is used in a strip edge wiper device.
