An automatic cardboard placing device for anode carbon block baking

Abstract

The present application discloses an automatic cardboard placement device for anode carbon block roasting, which can drive the lifting mechanism to drive the suction cup to descend under the action of a vertical cylinder so that its suction port contacts and sucks the cardboard tightly. When receiving the rising signal sent by the first displacement sensor, the lifting mechanism together with the suction cup drives the cardboard to start rising under the action of the vertical cylinder. When it rises to the top of the cardboard and contacts and clamps the cardboard with the cardboard clamping mechanism, the air source of the suction cup is disconnected to make the suction cup separate from the cardboard. Under the action of the horizontal cylinder, the cardboard is transported between two anode carbon blocks through the cardboard clamping mechanism. When the distance between the two anode carbon blocks detected by the second displacement sensor is less than the set value, the air pump is controlled to disconnect the air source of the cardboard clamping mechanism, and the cardboard performs free fall movement and enters between the two anode carbon blocks. This reciprocating cycle can realize the automatic addition of cardboard in the grouping process, thereby improving work efficiency, reducing manual labor intensity and ensuring the safety of cardboard adding operations.

[0002] In the process of producing charcoal blocks, the marshaling machine in the roasting workshop is mainly used to marshal the raw blocks for loading into the furnace in the form of a group of 7 blocks and 2 groups side by side, so that the multi-functional overhead crane can clamp and load them into the furnace. With the optimization of the molding formula, the asphalt ratio is also increased, which causes serious adhesion of charcoal blocks during the roasting process. In order to solve the problem of sticking blocks, each shift is equipped with one operator, whose main job is to add cardboard between two charcoal blocks.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0022] The core of this application is to provide an automatic cardboard placement device for anode carbon block roasting, which can solve the problem of manually adding cardboard between two carbon blocks in the prior art, resulting in high labor intensity, low production efficiency and easy occurrence of operational safety accidents.

[0023] Figure 1 A schematic diagram of the structure of an automatic cardboard placement device for anode carbon block roasting provided by an embodiment of the present invention. Figure 2 This is an enlarged view of point A provided in an embodiment of the present invention. Figure 3 A schematic diagram of a cardboard placement rack structure provided by an embodiment of the present invention is shown in FIG. Figures 1 to 3 As shown, the device comprises:

[0024] A cardboard placement rack 2 is arranged on one side of the marshalling machine equipment 1, and a first column 3 is fixed on one side of the cardboard placement rack 2. A second column 4 is arranged on the side of the marshalling machine equipment 1 away from the cardboard placement rack 2. A crossbeam 5 is fixed between the first column 3 and the second column 4, and the crossbeam 5 is located at the upper position between the two anode carbon blocks 6. A vertical cylinder 7 is arranged on one side of the first column 3, and a lifting mechanism connected to the vertical cylinder 7 through a pull rope 8 is installed in the first column 3. A suction cup 9 is rotatably arranged on the lower side of the front end of the lifting mechanism through a connecting assembly, and a first displacement sensor 10 is arranged on the connecting assembly. A connecting rod mechanism is rotatably arranged on one side of the connecting assembly, and the suction cup 9 is connected to the negative pressure fan through a connecting pipe. A horizontal cylinder 11 is arranged on the crossbeam 5, and a cardboard clamping mechanism is arranged on the horizontal cylinder 11. The cardboard clamping mechanism is connected to the air pump through a high-pressure air pipe, and a second displacement sensor 12 is arranged on the side of the marshalling machine equipment 1 close to the anode carbon block 6.

[0025] Specifically, the cardboard rack 2 is used to place the cardboard 02. The cardboard rack 2 corresponds to the lifting mechanism and the suction cup 9, and it is necessary to ensure that the suction cup 9 can fall onto the cardboard 02. The first column 3 is fixed to one side of the cardboard rack 2 by an expansion bolt 31 screwed under the ground, and the second column 4 is fixed to one side of the marshalling machine equipment 1 away from the cardboard rack 2 by an expansion bolt 31 screwed under the ground. The crossbeam 5 is fixed between the first column 3 and the second column 4. After installation, the crossbeam 5 is located above the two anode carbon blocks 6, which can ensure that the clamped cardboard 02 is accurately placed between the two anode carbon blocks 6. The size of the first column 3 and the second column 4 can be determined according to the overall size of the anode carbon block marshalling machine equipment 1.

[0026] The vertical cylinder 7 is fixedly arranged on one side of the first column 3. The first column 3 is a hollow structure. A lifting mechanism connected to the vertical cylinder 7 through a pull rope 8 is installed in the first column 3. As a preferred embodiment, the lifting mechanism includes a vertical rod 13 located in the first column 3. Rollers 14 are rotatably arranged at both ends of the vertical rod 13. The roller 14 at the upper end of the vertical rod 13 is fixedly connected to the sliding part 70 in the vertical cylinder 7 through the pull rope 8. A cross bar 16 is fixed at the middle position of the vertical rod 13. The suction cup 9 is rotatably arranged on the lower side of the front end of the cross bar 16. During actual installation, a pulley 32 is also arranged at the upper end of the first column 3. One end of the pull rope 8 is fixedly connected to the roller 14 at the upper end of the vertical rod 13, and the other end of the pull rope 8 is fixedly connected to the sliding part 70 after passing around the pulley 32. When the vertical cylinder 7 is started, the roller 14 can be driven to move up and down by the pull rope 8 through the up and down movement of the sliding part 70, thereby realizing the up and down movement of the cross bar 6 and the suction cup 9.

[0027] The suction cup 9 is rotatably arranged at the lower front end of the lifting mechanism through a connecting assembly, and a first displacement sensor 10 is arranged on the connecting assembly. The first displacement sensor 10 is used to detect whether the suction cup 9 is in close contact with the cardboard 02. The connecting rod mechanism is rotatably arranged at one side of the connecting assembly, which is used to control and adjust the angle of the suction cup 9. The suction cup 9 is connected to the negative pressure fan through a connecting pipe, and the air source is provided to the suction cup 9 through the negative pressure fan. The connecting pipe and the negative pressure fan are not drawn in the figure. As a preferred embodiment, the connecting assembly includes two mounting plates 17 fixed to the lower front end of the cross bar 16, a connecting rod 18 is fixed between the two mounting plates 17, and a movable rod 19 is sleeved on the connecting rod 18. A hollow cross bar 20 connected to the connecting pipe is fixed at the lower end of the movable rod 19. The suction cup 9 is fixed at the front end of the hollow cross bar 10, and a connecting rod mechanism is rotatably arranged at the rear end of the hollow cross bar 20. A limit rod 21 corresponding to the cross bar 16 is arranged on the hollow cross bar 20, and the first displacement sensor 10 is fixed at one end of the limit rod 21 close to the cross bar 16. As a preferred embodiment, the connecting rod mechanism includes a first connecting rod 23 which is rotatably arranged at the rear end of the hollow cross bar 20 by means of a screw rod 22, two second connecting rods 24 are fixed to one end of the first connecting rod 23, and rollers 25 are fixed to the lower ends of the two second connecting rods 24. The hollow cross bar 20 is similar to a pipe, and after being connected to the connecting pipe, the negative pressure air source generated by the negative pressure fan can reach the suction port of the suction cup 9 after passing through the connecting pipe and the hollow cross bar 20 to suck the cardboard 02 tightly.

[0028] The horizontal cylinder 11 is fixed on the crossbeam 5. A cardboard clamping mechanism is provided on the horizontal cylinder 11. The cardboard 02 can be clamped by the cardboard clamping mechanism. The cardboard clamping mechanism is connected to the air pump through a high-pressure air pipe. The air pump provides an air source for the cardboard clamping mechanism. The second displacement sensor 12 is provided at a side position of the marshalling machine equipment 1 close to the anode carbon block 6. The distance between the two anode carbon blocks 6 is detected by the second displacement sensor 12. As a preferred embodiment, the cardboard clamping mechanism is two air claws 26 connected to the sliding member 15 on the horizontal cylinder 11. The air claws 26 are connected to the air pump through a high-pressure air pipe. The high-pressure air pipe and the air pump are both drawn in the figure. As a preferred embodiment, the vertical cylinder 7 and the horizontal cylinder 11 are both magnetic piston rodless cylinders.

[0029] In actual use, when the suction cup 9 descends with the help of the vertical cylinder 7, the rollers 25 on the two second connecting rods 24 first contact the cardboard 02. At this time, the connecting rod mechanism drives the connecting assembly to automatically move, adjusts the direction of the suction cup 9 by 90°, so that the suction port of the suction cup 9 is downward and closely fitted with the cardboard 02. At the same time, the suction cup 9 is provided with an air source through the negative pressure fan. When the first displacement sensor 10 detects that the distance between the suction cup 9 and the cross bar 16 is less than the set value (that is, an upward signal is sent), it means that the suction cup 9 has sucked the cardboard 02. The suction cup 9 starts to rise under the action of the vertical cylinder 7. Under the action of the gravity of the connecting rod mechanism, the suction cup 9 will drive the cardboard 02 to change its direction by 90° again so that the suction port of the suction cup 9 and the fitted cardboard 02 remain vertical and rise. When lifting, the upper end of the cardboard 02 enters the clamping plates of the two air claws 26, and after ensuring that the clamping plates clamp the upper end of the cardboard 02, the negative pressure fan is controlled to disconnect the air source of the suction cup 9, so that the suction cup 9 loses the suction force on the cardboard 02. After the air source of the suction cup 9 is cut off, the air claw 26 moves linearly along the horizontal cylinder 11 to transport the clamped cardboard 02 to between the two anode carbon blocks 6 of the marshalling machine equipment 1, and when the second displacement sensor 12 detects that the distance between the two anode carbon blocks 6 is less than 100mm, the air pump is controlled to automatically disconnect the air source of the air claw 26, so that the cardboard 02 moves freely into between the two anode carbon blocks 6. The entire control process can be realized through the PLC control system, and a working cycle ends and repeats. At present, the working cycle time is set within 38 seconds, and it can be adjusted appropriately according to the actual situation on site; in a cycle, each mechanism can work independently, interlock with each other, and delay, which is used to control the action time of each mechanism and the total working time of a cycle, so as to realize the operation of automatically adding cardboards in the whole marshaling process. The suction cup 9 can automatically change the angle by relying on purely mechanical connecting components and connecting rod mechanisms without the help of external power sources. The combination of the suction cup automatic conversion mechanism (suction cup, connecting components and connecting rod mechanisms), vertical cylinders and horizontal cylinders can complete the placement of marshaling cardboards, and the degree of automation and work efficiency are both high.

[0030] As a preferred embodiment, the cardboard placement rack 2 includes a placement plate 27, a plurality of support rods 28 are arranged on the lower side of the placement plate 27, and a plurality of stop rods 29 are arranged at the upper edge of the placement plate 27. In order to improve the placement stability of the cardboard placement rack 2, as a preferred embodiment, a bottom plate 30 is also arranged at the bottom of each support rod 28.

[0031] According to on-site measurements, the automatic addition of 6 sheets of cardboard to each group of charcoal blocks can be completed continuously and without obstacles during the roasting grouping process, with an efficiency of 80 sheets per hour, which greatly improves the grouping efficiency and reduces the labor intensity of employees. The research and development and application of an automatic cardboard adding device for roasting grouping has effectively solved the safety hazards caused by personnel frequently going up and down the marshaling manual platform and manually adding cardboard. The research and development and application of an automatic cardboard adding device for roasting grouping has realized unattended operation and achieved the goal of reducing staff and increasing efficiency. The roasting workshop alone can reduce 8 people, saving 560,000 yuan in labor costs each year.

[0032] The present application provides an automatic cardboard placement device for anode carbon block roasting. In actual use, the vertical cylinder can be started to drive the lifting mechanism to descend through a pull rope so that the suction port of the suction cup contacts the cardboard placed in the cardboard placement rack, and the negative pressure fan is controlled to provide a negative pressure air source for the suction cup to suck the cardboard. When the rising signal sent by the first displacement sensor is received, the lifting mechanism and the suction cup are driven to rise by the pull rope through the vertical cylinder. When the cardboard rises to the top and contacts the cardboard clamping mechanism and clamps the cardboard through the cardboard clamping mechanism, the negative pressure fan is controlled to disconnect the suction. The air source of the disk makes the suction cup separate from the cardboard, and at the same time controls the horizontal cylinder to drive the cardboard clamping mechanism and the cardboard to move in a straight line along the crossbeam to transport the cardboard to between the two anode carbon blocks, and at the same time controls the two anode carbon blocks to be close. When the distance between the two anode carbon blocks detected by the second displacement sensor is less than the set value, the air pump is controlled to disconnect the air source of the cardboard clamping mechanism, so that the cardboard moves freely into between the two anode carbon blocks. This reciprocating cycle can realize the automatic addition of cardboard during the grouping process, thereby improving work efficiency, reducing labor intensity and ensuring the safety of cardboard adding operations.
