Description

  The present invention relates to a cathode plate cutting device obtained by non-ferrous metal refining, and more particularly to a cutting device that converts a cathode plate from a strip-shaped plate material into a rectangular piece.

  For example, after leaching nickel-containing sulfide ore to obtain a nickel chloride solution, electrical nickel is separated and removed from the nickel chloride solution to obtain a high-purity nickel chloride solution. Obtained by purification.

  One of the main uses of electrical nickel is as an anode for nickel plating. For such applications, electro nickel obtained as a cathode plate by electrolytic purification is cut into various sizes, for example, 100 mm □, 50 mm □, 25 mm □, etc. (see Patent Document 1).

  For such electrical nickel cutting, a nickel cathode cutting facility as schematically shown in FIG. 4 is used. First, in a primary cutting apparatus, a cathode having a size of 1000 mm × 800 mm and a thickness of 10 mm is cut into 10 strip-shaped plates having a size of 100 mm × 800 mm and a thickness of 10 mm. The

  The 10 strip-shaped plate materials obtained were automatically sent to the secondary cutting device, placed on the table of the secondary cutting device, and back gauge provided in front of the table by the pusher device To be aligned. Thereafter, the plate material is fixed to the table from above by a plate pressing device, and is cut into rectangular pieces having a size of 100 mm □ and a thickness of 10 mm by a cutting blade. Thereafter, after the rectangular piece is discharged downward, the fixing by the plate holding device is loosened, aligned by the pusher device, and then fixed and cut again. By repeating such operations, for example, 80 rectangular pieces are obtained.

  The above operation is automatically performed including the conveyance of the strip-shaped plate material. Finally, the obtained rectangular piece is automatically packed by a packing machine and sent to the user.

However, when the strip-shaped plate material is placed on the table of the secondary cutting device or when it is pressed against the back gauge by the pusher device, it rides on the other strip-shaped plate material and these are superimposed. May end up. If cutting is performed in such a state, the obtained piece is not rectangular and becomes a deformed product. Since such a deformed product causes quality complaints from the user, it is necessary for the operator to constantly monitor and remove the deformed product. There is a problem that it is necessary to remove the deformed product by manual work, and the work involves a great risk. In addition, since the deformed product does not become a product, there is a problem that the yield of the product is reduced due to the generation of the deformed product.

  The present invention provides a cutting apparatus capable of saving labor for an operator and improving product yield by improving work safety in a cutting process in which a cathode plate is formed from a rectangular plate material into a rectangular piece. The purpose is to provide.

  The inventors of the present invention have made various studies to solve the above problems, and as a result, when the strip-shaped plate material is superposed, the plate pressing device that fixes the strip-shaped plate material to the table from above is provided. Focusing on the fact that the height is not uniform, the present invention has been completed.

  The cathode plate cutting device according to the present invention relates to a cutting device that continuously cuts a cathode plate from a strip-shaped plate material into rectangular pieces by a table and a cutting blade.

  The cutting device is provided with a plurality of pressing plates that move up and down in order to fix the strip-shaped plate material to the table from above, and in the present invention, in particular, by overlapping the strip-shaped plate material, And an optical sensor for detecting an abnormal displacement of the pressing plate.

  Preferably, the optical sensor includes a light emitter and a light receiver, and the pressing plate at a position for releasing the strip-shaped plate material blocks light from the light emitter to the light receiver, and the strip shape. The pressing plate in a position for fixing the plate material is one of the pressing plates that have passed light from the light emitter to the light receiver and stopped at an abnormal position due to superposition of the strip-shaped plate material. The light emitter and the light receiver are arranged so as to block light from the receiver to the light receiver.

  It is preferable that after the pressing plate is started, the cutting blade is controlled to be started after the optical sensor detects that the pressing plate is not displaced due to the overlap of the strip-shaped plate materials. .

  The cathode material cutting facility according to the present invention includes a cathode material supply device, a primary cutting device that cuts the cathode material into strip-shaped plate materials, and a secondary cutting device that cuts the strip-shaped plate materials into rectangular pieces. And a packing device for packing the rectangular piece, and in particular, the secondary cutting device comprises the cutting device described above.

  According to the present invention, it is possible to detect an abnormality in which strip-shaped plate materials are overlapped, and to stop the automatic cutting operation, and it is possible to prevent the generation of a deformed product. Therefore, it is not necessary to constantly monitor abnormalities in the fixed state of the strip-shaped plate material, or to remove the deformed product in the middle of automatic cutting work when a deformed product occurs. The labor saving, improvement of safety, and improvement of product yield can be obtained. Furthermore, the effect that improvement of nickel metal loss is realizable is also acquired.

  The present invention can be applied not only to electric nickel but also to a metal cathode plate obtained by electrolytic refining such as electric cobalt, which is produced by cutting the cathode plate.

  The present invention will be described with reference to the drawings. FIG. 1 shows an abnormal state where a plurality of pressing plates (7) are trying to fix a strip-shaped plate material (2) in the embodiment of the cutting apparatus of the present invention, but the plate material (2) is superposed. FIG. 1A is a front view (FIG. 1A) and a plan view (FIG. 1B). 2 is a front view (FIG. 2A) and a plan view (FIG. 2B) showing a normal state in which the plurality of pressing plates (7) fix the strip-shaped plate material (2) in the cutting device of FIG. 1. FIG. 3 is a front view showing a state where the plurality of pressing plates are in the standby position (starting position) and the strip-shaped plate material is released in the cutting apparatus of FIG.

  In one embodiment of the cutting device of the present invention, the cutting device is made from a strip plate (2) to a rectangular piece by means of a table (1) and a cutting blade (9) as in the conventional structure. Cut continuously. A predetermined number of strip-shaped plates (2) are arranged on the table (1) in the vertical direction. A back gauge (4) is disposed in front of the table (1) (front in FIGS. 1A and 2A, and downward in FIGS. 1B and 2B), and one end of the strip-shaped plate (2) is the back gauge. It is pressed by the pusher device (3) from the other end side so as to come into contact with (4).

  A plurality of pressing plates (7) are arranged above the table. The pressing plate (7) is movable in the vertical direction by the plate pressing device (6), and moves downward from the standby state (FIG. 3) to the fixed state (FIG. 2) of the strip-shaped plate (2). The number of the pressing plates (7) is arbitrary, but the strip plate (2) is pressed against the table (1) from above for the total length in the width direction of the strip plate (2) as a whole. It is designed to be fixed. In the illustrated example, there are six plate pressing devices (6) and six pressing plates (7), but the present invention is not limited to this.

  In the fixed state, the cutting blade (9) is lowered and cuts a part of the strip-shaped plate (9). The interval between the back gauge (4) and the table (1) can be changed as desired.

  After cutting, the obtained rectangular piece is discharged downward, and the pressing plate (7) is moved upward to release the strip-shaped plate (2). In this state, the strip plate (2) is advanced by the pusher device (3), and is fixed again by the pressing plate (7) in a state where one end thereof is in contact with the back gauge (4).

  In the present invention, optical sensors are provided above the table and at both ends in the width direction of the table. The optical sensor includes a light emitter (5) and a light receiver (8). The light emitter (5) and the light receiver (8) are arranged at substantially the same height as the holding plate (7) in the standby state. Therefore, in this state, as shown in FIG. 3, since the light transmitted from the light emitter (5) is blocked by the pressing plate (7), it does not reach the light receiver (8).

  When the pressing plate (7) starts from the standby state and moves downward to the normal fixing position (FIG. 2) of the strip-shaped plate (2), the above-described blocking state is canceled and light transmitted from the light emitter (5) is transmitted. Passes to the light receiver (8) and reaches.

  However, abnormalities may occur when aligning or moving the strip-shaped plates (2), and some strip-shaped plates may ride on other strip-shaped plates and overlap with the strip-shaped plates (2). In this case, as shown in FIG. 1, a part of the pressing plate (7) does not move downward to the normal position, but stays at the standby position or an abnormal position in the vicinity thereof, and similarly to the standby state, the light emitter (5 ) Is blocked by a part of the pressing plate (7) so as not to reach the light receiver (8).

  Thus, by arranging the light emitter (5) and the light receiver (8), an abnormality that the strip-like plate (2) overlaps is detected by the abnormal displacement of the pressing plate (7).

  The cutting device according to the present invention further includes a mechanism (not shown) for controlling the cutting blade, connects the optical sensor to the control mechanism, and after the pressing plate (7) is started from the standby position, the cutting device is normally lowered. It is preferable to control so that the cutting blade (9) is started only after the optical sensor detects that there is no abnormality that the strip plate (2) overlaps.

  In addition, although the example which used the light emitter and the light receiver as mentioned above was shown as an optical sensor, it is not restricted to this example, The well-known which can recognize the displacement with the normal state and abnormal state of a holding plate (7) It is possible to use the optical sensor system.

  In the cutting apparatus according to the present invention configured as described above, as shown in FIG. 3, the strip-like plate (2) is neatly aligned on the table (1) at the time of normal start-up, and thereafter, FIG. As shown in FIG. 2, the strip plate (2) is pressed against the back gauge (4) by the pusher device (3), the plate pressing device (6) is operated, and the pressing plate (7) is lowered. Then, the strip plate (2) is fixed.

  In this state, light from the light emitter (5) to the light receiver (8) passes over the holding plate (7), and a signal indicating that the light is received is sent as an output signal to a control device (not shown). . After the control device confirms that the plate pressing device (6) is operating normally and that the light emitted from the light emitter (5) is detected by the light receiver (8), the control device is operated by the cutting blade. An output signal for lowering (9) is output. After reaching the bottom dead center, the cutting blade (9) rises and reaches the top dead center (starting position) and stops.

  On the other hand, as shown in FIG. 1, in the abnormal state where one strip-shaped plate (2) rides on both adjacent strip-shaped plates, even if the plate pressing device (6) is operated, the two pressing plates (7) However, it does not descend to the normal position. As a result, the light from the light emitter (5) is blocked by the pressing plate (7) and does not reach the light receiver (8). By sending this state as an output signal to the control device, the control device confirms that the plate pressing device (6) is operating, but the light emitted from the light emitter (5) is received by the light receiver. The state that it is not detected in (8) can be detected, the output signal for lowering the cutting blade (9) is not issued, and the automatic cutting operation is stopped.

  Therefore, the worker can safely perform the work of correctly aligning the strip-shaped plates that are on board. After that, the plate pressing device (6) is returned to the starting state and then restarted again, and only when the operation of the plate pressing device (6) and the light reception by the light receiver (8) are detected at the same time, cutting is performed. It is preferable to control so as to allow the blade (9) to descend.

  The cutting device according to the present invention includes a cathode material supply device, a primary cutting device that cuts the cathode material into strip-shaped plate materials, and a secondary cutting device that cuts the strip-shaped plate materials into rectangular pieces. And a cutting facility provided with a packing device for packing the rectangular pieces, the present invention is optimally applied to the secondary cutting device.

  As a secondary cutting device of the nickel cathode cutting equipment schematically shown in FIG. 4, using the cutting device of the present invention, 500 cathode plates having a size of 1000 mm × 800 mm and a thickness of 10 mm are used. An operation of continuously cutting into 40,000 rectangular pieces having a thickness of 100 mm □ and a thickness of 10 mm was performed.

  Specifically, each cathode plate obtained by electrolytic refining was cut into 10 strip-shaped plate members of 100 mm × 800 mm and a thickness of 10 mm using a primary cutting device. Thereafter, the ten strip-shaped plate members are aligned in the length direction and introduced into a secondary cutting apparatus, and the cutting is repeated seven times in the length direction, and eight rectangular plates are formed from each strip-shaped plate member. A shape piece was obtained. The obtained rectangular piece was then transported to a packing machine and automatically packed.

  When all the cathode plates were automatically subjected to the above operation, a total of 26 operations were stopped due to the overlap of the strip-shaped plate materials. In each case, the strip-shaped plate was rearranged and the work was resumed, so that there were no odd-shaped pieces. In addition, during normal automatic work except during work stoppage due to the above-described abnormality, the operator was able to engage in work other than monitoring work, so the overall work efficiency increased.

In one Example of the cutting device of this invention, it is a front view which shows the state which the overlap produced. It is a top view which shows the state which overlapped in one Example of the cutting device of this invention. It is a front view which shows a normal state in the cutting device of FIG. It is a top view which shows a normal state in the cutting device of FIG. It is a front view which shows the time of starting in the cutting device of FIG. It is the schematic which shows a nickel cathode cutting equipment.
