[0002] The unmanned whole process of temperature measurement and sampling is one of the key technologies for the intelligent transformation of steel enterprises in recent years to realize the unmanned production of smelting stations, and it is also a necessary measure to reduce the number of "3D" jobs. The temperature measurement process is relatively simple, and it is common to realize automated operation. In addition to sampling from molten steel (iron), the automation of the whole process of sampling also includes the separation and automation of samples from the sampler. At present, only the automation of sampling is basically realized in China, and the separation and delivery of samples are almost entirely dependent on manual labor.

It is most widely used in the RH station of silicon steel production. At present, there is no record of the use of the whole process unmanned sampling system of bucket-type samplers in China. Its current operation method is: manually fix the bucket sampler on the gun rod of the manual temperature measuring gun or the gun rod of the automatic lifting gun. When sampling, manually hold the gun body to take samples or operate the automatic lifting gun to lift and lower for sampling. After taking the molten steel sample, manually remove the sampler from the gun body, and then manually take out the sample from the bucket and remove the slag. After bottling the sample, send it to the pneumatic sample sending and receiving cabinet and manually send it to the inspection and testing laboratory.

DETAILED DESCRIPTION

[0011] The present invention is further described below in conjunction with embodiments and accompanying drawings.

[0012] Example 1 The bucket-type sampler full-process unmanned sampling system of the present invention comprises a sampling gun tool end, a sampling gun calibration device, a bucket-type sampler storage rack, an automatic sample processing device, and an automatic sample sending device.

[0013] 1) Sampling gun tool end Please refer to Figure 1 , Figure 1The schematic diagram of the sampling gun structure of the embodiment of the present invention is shown in the figure. As shown in the figure, the tool end of the sampling gun is an L-shaped rod, one end of the rod is a tool tray connection block 1, the tool tray connection block is connected to the tool quick-change tray 2 and the sub-disc connection frame 3, the other end of the rod is a bucket sampler 8, the end of the bucket sampler is connected to the top of the sub-disc connection frame 3 through the sampling gun body 4, a connecting rod 6 is arranged parallel to the sampling gun body 4, one end of the connecting rod is connected to the bucket sampler and the sampling gun body through a cam 7, and the other end of the connecting rod is connected to the corner of the L-shaped rod through a cylinder 5.

[0014] Working mode of the sampling gun tool end: The sampling gun is used to collect, fix, and release the bucket sampler. When collecting, the robot moves the sampling gun installed on the tool end to the bucket sample storage rack. After the bucket rod head is guided to the set distance by the gun head guide hole, the cylinder pushes the connecting rod and drives the cam to rotate. The cam supports the bucket rod body, so that the bucket is firmly positioned and cannot move or rotate. When releasing, the cylinder retreats, the cam moves away, and the bucket is loosened.

[0015] 2) Sampling gun calibration device Figure 2 This is a schematic diagram of the structure of a sampling gun calibration device according to an embodiment of the present invention. Figure 3 for Figure 2 The sampling gun calibration device is provided with a bottom plate 9, a sleeve support 10 is provided on the upper surface of the bottom plate, a sleeve device 12 is provided above the sleeve support, two cylinders of the sleeve device can move a certain distance through a spring 13 provided between the cylinders, and a proximity switch 11 is provided at a certain distance.

[0016] The working mode of the sampling gun calibration device is to calibrate the centerline accuracy of the sampling gun and ensure the position accuracy of the installation bucket. During the inspection, the sampling gun is translated by the robot according to the position where the centerline of the sleeve is concentric with the centerline of the gun body, and the gun head is extended into the sleeve for a certain distance. When the deformation of the gun head is within the range of the inner diameter of the sleeve, the gun head will not touch the sleeve, and the sleeve will not move and trigger the proximity switch signal. This indicates that the gun body is normal. When the deformation exceeds the range, the gun head will touch the sleeve plate and push the sleeve to move, and trigger the proximity switch signal, which indicates that the gun body needs to be replaced or straightened.

[0017] 3) Bucket sampler storage rack Figure 4 This is a schematic diagram of a bucket sampler storage rack according to an embodiment of the present invention. Figure 5 for Figure 4 Side view of Figure 6 for Figure 4Enlarged view of the P part in the middle. The bucket sampler storage rack is a welded steel structure. The bucket relies on the two V-shaped grooves on the storage rack crossbeam to achieve center positioning; the bucket relies on its own weight to achieve circular angle positioning; the bucket sticks to the baffle beam of the storage rack to achieve axial positioning. Therefore, accurate installation can be achieved through the robot's set trajectory. This method can also avoid the influence of the diameter and length errors of the bucket rod on the installation accuracy of the bucket.

[0018] 4) Automatic sample processing device Figure 7 The structure diagram of the automatic sample processing device of the embodiment of the present invention is shown in FIG. The automatic sample processing device includes a stand 24, which is a cross-shaped bracket, and a platform is provided on the top of the cross-shaped bracket. A cylinder 20 is provided on one side of the platform. The cylinder is connected to the flip chute device 16 through a push rod 19. The flip chute device 16 is connected to the valve station and the piping 15 upward. The valve station and the piping are further connected to the shelling device 14 upward. The flip chute device 16 passes downward through the platform to the cross-shaped bracket to vertically set the slag collection chute 18. The flip chute device 16 is horizontally connected to the transition chute 17. The transition chute 17 is bent downward and connected to the platform. It is connected to the weighing device 21, and then bends downward through the lower slide pipe 22 to be connected to the photoelectric sensor 23 arranged on the side of the cross-shaped bracket. The photoelectric sensor is set on the ground through a support. The main body of the automatic sample processing device is an electromechanical integrated device, including a valve station and a terminal box. The valve station and the terminal box are fixed together with the stand, and are equipped with all the on-machine piping and wiring. The function of the automatic sample processing device is to separate the sample from the bucket container, clean the sticky residue, and perform quality analysis. At the same time, the sample is transported to the next process (the sample is automatically sent).

[0019] The working mode of the automatic sample handling device is as follows: after the lifting bucket with the sample is in place, the shelling device is driven by the cylinder to swing into place, and the vibrating head of the side vibrator is attached to the lifting bucket for high-frequency vibration, so that the sample and the barrel wall, the sticky residue at the barrel mouth and the barrel body are separated. At the same time, the pneumatic impact hammer on the top hits the bottom of the barrel, so that the sample is completely separated from the lifting bucket and falls into the lower flip chute. Most of the sticky residue is separated and falls from the vertical collection chute after impact. At this time, after the sensor senses the sample, the flip chute is turned 90 degrees, the sample posture is adjusted to a horizontal state, the push rod is pushed out, and it is pushed in from the tail of the sample. When passing through the conical transition chute, the sticky residue of the sample is shaped and cleaned. During this period, the two nitrogen purges are opened at the same time to clean the residue. When the sample falls from the transition chute to the chute section of the weighing device, it is blocked by the support rod for weighing, and then the support rod is retracted, and the sample slides along the lower chute to the receiving position of the sending device. The photoelectric sensor here senses the signal, and the automatic sample sending device starts to work.

[0020] 5) Automatic sample sending device The automatic sample sending device includes the robot 25, which is arranged beside the sample receiving platform 26. A sample bottle 27 station is arranged below the bottle cap opening and closing mechanism 28, and the bottle cap opening and closing mechanism 28 is connected to the sample receiving and sending cabinet 29 and the control cabinet 30 beside it.

[0021] The function of the automatic sample processing device is to realize the automatic bottling and sending of samples, automatic processing of empty bottle returns, etc.

[0022] Figure 8 This is a schematic diagram of the automatic sample sending device of an embodiment of the present invention. The working method of the automatic sample processing device: after receiving the sample arrival signal, the robot grabs the sample, puts it into an empty bottle, and then places the bottle into the bottle cap opening and closing mechanism station. The cylinder of the opening and closing mechanism moves to press the bottle cap from the top into the bottle mouth to realize the capping function. After the cylinder returns, the robot grabs the bottle and places it in the sending position of the delivery cabinet, and then returns to the standby position. The door of the sample delivery cabinet is closed, and the pneumatic sample delivery starts to execute, and the sample bottle is transported to the laboratory. At this point, the automatic sample delivery work is completed.

[0023] When the empty sample bottles in the laboratory are transported back to the receiving and dispatching cabinet, the robot places the bottles on the bottle cap opening and closing mechanism, which opens the bottle caps. Then the robot places the empty bottles without caps on the waiting bottling position, waiting for the next sample to arrive.

[0024] The present invention has substantial characteristics and significant technical progress. The present invention is a full-process unmanned sampling system for a bucket-type sampler. The robot completes the replacement of the sampling gun at the tool end in advance (the tool end was previously a temperature measuring gun), and then installs the bucket from the bucket storage rack according to the current set position. After completion, it moves to the molten steel for sampling, and then sends the bucket with the sample to the automatic sample processing device. After the sample is separated from the bucket, the robot takes the empty bucket to the recycling box and removes it, then moves it to the sampling gun calibration device for gun body calibration, and then returns to the standby position. After the sample is separated from the bucket, the sample is cleaned and weighed in the automatic sample processing device, and then slides from the slide pipe to the designated workstation. The sample is automatically sent to the robot to pick up the sample and put it into the sample bottle, and then sent to the opening and closing position of the sample bottle cap. After closing the bottle cap, the sample bottle is placed in the sample receiving and sending cabinet and sent to the laboratory. After the empty bottle in the laboratory is returned, the robot picks up the bottle from the receiving and sending position and performs preparations such as opening the cap.

[0025] The above embodiments are only for the purpose of illustrating the present invention, but not for limiting the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and should be defined by the claims.
