Description

Separate storage device for steel type of stainless scrap

The present invention relates to a device that separates and scraps generated in the production plant of stainless steel and strip steel sheet into the scrap box after the separate collection by steel type, more specifically because it does not need to work with a crane hook The accident prevention is prevented, and a plurality of scrap boxes can be disposed in a variety of steel grades can be processed at a time, and the present invention relates to a separate storage device for steel types of improved stainless steel scrap.

In general, in the steel lines (100a) (100b) for producing a stainless steel sheet or strip steel sheet, such as strips (S) (Sb) through two passlines (100a) (100b) arranged up and down as shown in FIG. ) And produce various steel grades.

The strip steel sheet is cut at the front and rear ends of each of the pass lines 100a and 100b by the cutter 110, and generates scraps (steel plate pieces) P for each steel type. On the other hand, the scrap (P) as described above is collected separately for each steel type, if only two kinds of steel are produced through the two pass lines (100a, 100b) only two scrap boxes (120a, 120b) need be However, when a plurality of kinds of strips Sa and Sb are produced in each of the passlines 100a and 100b, the kinds of scrap generated therein also increase relatively. In this case, conventionally, as shown in Figure 1, the scrap box 120a (120b) currently mounted on the scrap box moving trolley 130 that can hold a plurality of kinds of scrap (P) by the crane work, The new scrap boxes 120c and 120d, which could contain new steel scraps, were replaced by cranes and mounted on the mobile cart 130.

On the other hand, such a conventional scrap box replacement work because the scrap moving cart 130 is mounted underground, the work takes a long time during the replacement work by the crane, the work load of the operator is large, there is a very high risk of safety accidents It was high.

Therefore, the conventional working method as described above is counterproductive and lowers working efficiency.

The present invention is to solve the conventional problems as described above, the purpose is that there is no need to do the crane hook work, safety accidents are prevented, and by placing a plurality of scrap boxes can be processed several kinds of steel at once The present invention is to provide a separate storage device for each type of stainless steel scrap improved work efficiency.

Therefore, when the rod 50b is moved back and forth by the operation of the rotary cylinder 50, the shaft 45 is rotated at a predetermined angle through the link 54, the bucket 40 connected to the shaft 45 To rotate at an angle.

And, one side of the rail (5) is provided with a plurality of scrap (P) box 60a, 60b, 60c, 60d arranged side by side in steel, each of which can be arranged in line for each steel produced will be. In addition, the strip (Sa) (Sb) steel grades from the strip pass line (100a), 100b (100b) in accordance with a predetermined operation program is connected to the trolley 10, the lifting unit 20 and the rotating unit 42 to be operable The controller 70 has a controller 70 which separates the scraps P into the plurality of scrap boxes 60a, 60b, 60c, and 60d, respectively, by varying their positions. 22, a plurality of sensors 75a, 75b, 75c for detecting the position of the platform 24 and transmitting an electrical signal, and a plurality of the positions for which the moving cart 10 detects the position on the rail 5; Two sensors 75d, 75e, 75f ', 75f', 75f '", 75f'", and sensors 75g for detecting rotation of the bucket 40.

In the above, the sensors 75a, 75b and 75c detect the bucket 40 located on the vertical stage 22 on the upper stage 1 strip pass line 100a and transmit an electric signal. 75c), a second sensor 75b for detecting the position of the bucket 40 on the vertical stand 22 in the lower two-stage strip pass line 100b, and transmitting an electrical signal, and the vertical stand 22; A third sensor 75c for detecting the position of the bucket 40 in the home position and transmitting an electrical signal thereon is provided.

In addition, the plurality of sensors 75d, 75e, 75f ', 75f', 75f '", 75f" "for which the mobile trolley 10 detects a position on the rail 5 are the mobile trolley ( 10 is advanced to the side of the strip pass lines 100a and 100b to detect that the first and second pass lines 100a and 100b have reached the position where the scrap P can be received in the bucket 40. Four sensors 75d, a fifth sensor 75e for detecting that the moving trolley 10 is positioned at the home position on the rail 5, and scrap boxes 60a, 60b, 60c on the rail 5 side. Each scrap box to indicate that the trolley 10 is located in each scrap box 60a, 60b, 60c, 60d so as to move the scrap P in the bucket 40 into the 60d. Sensors 75f ', 75f ", 75f'", 75f "" provided for each 60a, 60b, 60c, 60d are provided.

In addition, the sensor 75g for detecting the rotation of the bucket 40 is provided, which is mounted on one side of the shaft base 47, the detection plate 54a attached to the link 54 is the sensor 75g When it is rotated to the side), it detects this and detects whether the bucket 40 has been rotated by the rotation cylinder 50 and transmits an electrical signal to the controller 70.

On the other hand, the sensor 75a, 75b, 75c, 75d, 75e, 75f ', 75f ", 75f'", 75f "", and the like above.

(75g) are not shown clearly in the mounting structure on the accompanying drawings, but they can be fixed in place by a bracket (not shown) or a support, respectively, depending on the installation conditions of the site, because the mounting structure is not unusual The detailed description will be omitted here and only the approximate location will be shown.

Stainless steel separate storage device (1) of the invention according to the present invention configured as described above, as shown in Figure 5, in the first home position to move the bucket 40 to the desired strip pass line, scrap for each steel type The scraps P can be transferred to the boxes 60a, 60b, 60c and 60d. This means that if the scrap P is to be received and moved from the lower two-stage strip pass line 100b as shown in Fig. 5a), the operator operates the controller 70 so that the moving cart 10 is railed. In step (5), when the position is detected by the fourth sensor 75d, the driving of the moving cart 10 is stopped.

Then, the driving cylinder 26 of the elevating unit 20 is operated to move the elevating table 24 and the bucket 40 coincides with the second stage pass line 100b. Even in this case, when the platform 24 reaches the position of the second sensor 75b, the operation of the driving cylinder 26 is stopped. Therefore, the bucket 40 reaches a position to receive the scrap P generated at the lower portion of the second pass line 100b, and scraps the inside of the bucket 40 from the second pass line 100b. Upon receiving P), the controller 70 moves the moving cart 10 back on the rail 5 so that the bucket 40 can be any one of the scrap boxes 60a, 60b, 60c and 60d. (Assuming 60a on 5b).

In this case, the position of each scrap box 60a, 60b, 60c, 60d is determined by the sensors 75f ', 75f ", 75f'", 75f "" located on its front side. Is detected. Therefore, when the moving cart 10 is completed moving to the scrap box 60a side in which the scrap P of steel grade contained in the bucket 40 is to be loaded, the rotary cylinder 50 of the rotating part 42 is operated to lower the rod. By rotating the bucket 40 to the scrap box (60a) side and the scrap (P) in the interior is poured into the scrap box (60a). In this operation, the rotation of the bucket 40 is detected by the sensor 75g, and when the processing of the scrap P is completed, the moving cart 10 and the bucket 40 are grooved by the controller 70. Go to position and end the job.

This work process is basically performed in the same manner for each steel grade of the scrap (P), only the position of the bucket 40 receives the scrap (P) and the scrap (P) by steel type scrap (P) box 60a (60b) Only the position shift state is different depending on the movement to 60c and 60d.

According to the present invention as described above, since there is no need to replace the scrap boxes 60a, 60b, 60c, 60d as cranes, there is no need to carry out crane hook work, thereby preventing safety accidents in the workplace. By arranging a plurality of scrap boxes 60a, 60b, 60c, 60d, various kinds of steel can be processed at a time, thereby obtaining a practical effect of improving work efficiency.
