Description

Technical Field

[0001] The present invention relates to a gate of a bar and wire rod shearing material recognition system. Background Art

[0002] In the production process of bar and wire rod, a diameter gauge is generally used for on-line inspection of products. In the prior art, the diameter gauge is mainly used for size inspection and screening of abnormal products during the rolling process, and cannot provide timely and effective data for automatic control. Moreover, the measurement accuracy of the diameter gauge is easily affected by the environment and fluctuates. The high temperature during the rolling process of bar and wire rod will generate hot air flow, and vibration will occur while running at high speed. The higher the running speed, the faster the vibration frequency, and the more difficult it is to ensure the measurement accuracy. For traditional deformed steel bars with complex shapes, the diameter gauge cannot detect them when they are moving at high speed. The general inspection of the external dimensions of deformed steel bars is sampling inspection, that is, taking finished products from the production line and using special external diameter measuring tools for measurement. If manual monitoring is not timely, it will cause waste products with defects in appearance quality.

[0003] Therefore, a system for identifying shearing materials generated during the rolling process of bar and wire rod by using visual recognition technology has been developed. First, a shearing material collection device is arranged under the flying shear chute to collect and convey the shearing materials to a designated detection platform. After the shearing materials are visually recognized on the detection platform, including the length, outer diameter, crack, groove type, etc. of the shearing materials, the processed data information is finally transmitted to the control system to achieve high-precision detection of bar shearing materials, and finally conveyed to the waste bin through the chute. However, during the falling process of the shearing materials, for the need of cooling and cleaning, a gate that can be controlled to open and close needs to be designed; generally, a directly rising and falling gate plate will be impacted by the falling shearing materials during multiple uses. As the number of impacts increases, problems such as deformation of the gate plate, deformation of the driving connecting rod, and inability to open or close smoothly due to poor lifting of the gate plate will occur. Summary of the Invention

[0004] In view of the above problems, the present invention relates to a gate of a bar and wire rod shearing material recognition system.

[0016] The gate of the present invention is opened by a cylinder and a crankshaft to drive the gate plate to rotate counterclockwise, which is consistent with the discharging direction of the falling sheared material. Therefore, the sheared material will not be blocked when passing through the gate. After the gate plate is closed, the energy of the falling sheared material impacting the gate can be transmitted to the cylinder for absorption, thus effectively extending the service life of the gate plate and the cylinder. After the sheared material passing through the gate is visually recognized at the discharging port, including the length, outer diameter, crack, groove type, etc. of the sheared material, the processed data information is finally transmitted to the control system.

[0029] Figure 1 This is an embodiment of the present invention. The gate of the bar and wire shearing material identification system of the present invention is arranged on a chute inclined below the flying shear 99. The chute includes an inverted trapezoidal chute bottom plate 88, and two vertical plates 1 are arranged along the outlines on both sides of the upper surface of the chute bottom plate. A first collection box 10 is arranged at the lower opening of the chute; a second collection box 11 is arranged on one side of the chute, and a discharge port is arranged on the chute corresponding to the second collection box 11; a rotating plate 2 is vertically arranged on the chute bottom plate at the discharge port through a pin shaft 3 perpendicular to the chute bottom plate, and a chute 7 and a visual recognition device 9 are arranged outside the discharge port. The chute 7 can generally be selected as a V-shaped chute, and the visual recognition device 9 can be selected as a camera or a video camera that can be used for visual recognition according to needs. After the shearing material is visually recognized by the visual recognition device 9 on the chute at the discharge port, the length, outer diameter, crack, groove type, etc. of the shearing material can be obtained, and finally the processed data information is transmitted to the control system to achieve high-precision detection of the bar shearing material.

[0030] During operation, the rotating plate cylinder 4 drives the rotating plate 2 to rotate along the chute bottom plate so that it is in the first working position or the second working position; when the rotating plate is in the first working position (i.e., when the rotating plate rotates to the vertical plate on the right side of the chute), the material in the chute falls into the first collection box 10 along the chute, and when the rotating plate is in the second working position (i.e., when the rotating plate rotates to the vertical plate on the left side of the chute), the material in the chute enters the chute 7 along the chute and the rotating plate and falls into the second collection box 11 after passing through the chute 7.

[0031] A plurality of openings 42 are arranged on the bottom plate of the chute above the rotating plate, and the spray heads 41 are arranged in the openings on the chute. Each spray head is connected through a water pipe 411, and the water pipe is filled with pressurized cooling water.

[0032] A rotary gate is provided on the bottom plate of the chute at the discharge port. The rotary gate includes: a gate plate 51, on which a gate shaft is provided; a through hole is provided on the bottom plate of the chute, and the gate shaft passes through the through hole and is fixedly connected to a crank 52; a gate driving cylinder 53 is provided on the back of the bottom plate of the chute, and the free end of the gate driving cylinder is hinged to the free end of the crank; the gate driving cylinder drives the crank to drive the gate to turn outwards towards the discharge port.

[0033] A temperature measuring device (temperature sensor) 42 is installed through a temperature measuring bracket at the shear material water spraying and cooling place.

[0034] After the shear material falls along the rotating plate, it is blocked by the gate 51 and is sprayed and cooled through a nozzle; the temperature measuring device 42 detects the temperature of the shear material; when the shear material drops to the specified temperature and the radiant heat of the red-hot steel is eliminated, the gate 51 is opened;

[0035] As an improvement of the above embodiment, a fixing plate is provided on the chute, and the fixing plate is arranged on the extension line of the rotating plate when it is in the second working position; when the rotating plate rotates to the second working position, the rotating plate and the fixing plate together form a guide for the shear material. This can reduce the length of the rotating plate.

[0036] As an improvement of the above embodiment, a camera device (not shown in the figure) is provided on the right vertical plate inside the discharge port of the chute, which is used to take pictures or videos of the shear material to calculate the length, diameter, etc. of the shear material; the camera device can be set from 1 to 2 according to the actual situation. For example, one camera can be set at a lower position on the right vertical plate of the chute to facilitate obtaining the diameter of the shear material, and the other camera can be set at a higher position on the right vertical plate of the chute to facilitate obtaining the length of the shear material.

[0037] The control device can be the host or server of the camera device, which is used to calculate the length and diameter of the shear material according to the image of the camera device, and obtain its density according to the work order of the shear material, so that the control device can estimate the weight of the shear material;

[0038] A controlled angle adjustment device for adjusting the inclination angle of the chute is provided below the chute;

[0039] A controlled angle adjustment device 8 is provided below the chute; as shown in the figure, the angle adjustment device 8 consists of a bottom bracket and two front and rear lifting devices arranged on the bracket. The lifting device can be an electric lifting device or a hydraulic lifting device. Among them, the front lifting device is mainly used for angle adjustment during the equipment installation process (after working for a period of time, it is also necessary to adjust through the front long-lifting device to ensure the alignment of the front end of the chute and the discharge port). The rear lifting device is mainly used for angle adjustment during the working process; by adjusting the two front and rear lifting devices, the inclination angle of the chute 7 can be adjusted to control the sliding speed of the sheared material, which is beneficial for the visual recognition device to perform visual recognition.

[0040] In this way, the control device outputs a control signal to the controlled angle adjustment device according to the estimated weight of the sheared material to adjust the inclination angle of the chute.

[0041] As a further improvement of the present invention, the V-shaped chute 7 includes a front chute 71 and a rear chute 72 arranged at intervals corresponding to the discharge port. A connecting bracket 91 is arranged at the gap between the front chute and the rear chute. A plurality of camera devices 93 are arranged on the bracket; a light source 94 can be arranged between two adjacent camera devices; in order to facilitate the comprehensive shooting of the sheared material, a rotary pan-tilt 92 is arranged on the connecting bracket, and the camera device 93 is installed on the rotary pan-tilt 92.

[0042] As a further improvement of the present invention, as Figure 3 and Figure 7 shown, further, the cleaning device includes a bottom cleaning device and a side cleaning device; among them,

[0043] The bottom cleaning device includes: a guide plate 881 is arranged on the chute bottom plate below the rotating plate, and the guide plate is arranged on the extension line of the rotating plate when it is in the second working position; a lower hollow cavity 882 is arranged at the bottom of the guide plate, and a plurality of ventilation holes communicating with the lower hollow cavity are arranged on the part of the guide plate 883 corresponding to the lower hollow cavity. The lower hollow cavity is connected to compressed air through a pipeline 885;

[0044] The side cleaning device includes a side hollow cavity arranged on the back of the chute bottom plate in front of and / or behind the discharge port. A plurality of ventilation holes communicating with the side hollow cavity are arranged on the part of the chute bottom plate corresponding to the side hollow cavity. The side hollow cavity is connected to compressed air through a pipeline.

[0045] Compressed air blows against the surface of the sheared material in the reverse direction; to remove the residue on the surface of the sheared material, which is beneficial for the subsequent visual recognition of the sheared material.

[0046] A temperature measuring device (temperature sensor) 42 is installed through a temperature measuring bracket at the place where the sheared material is cooled by spraying water.

[0047] After the sheared material falls along the rotating plate, it is blocked by the gate 51 and cooled by spraying through the nozzle; the temperature measuring device 42 detects the temperature of the sheared material; when the sheared material drops to the specified temperature and the radiant heat of the red-hot steel is eliminated, the gate 51 opens.

[0048] As a further improvement of the above embodiment, a damping device is further provided above the rear chute, including a mobile cloud platform 36, a mobile cloud platform support frame 37, a rotary cylinder 38, a damping head 39, and a guide rail 361.

[0049] A mobile cloud platform support frame 37 is provided at the tail of the rear chute 32. A guide rail 361 is provided between the mobile cloud platform support frame 37 and the connecting bracket 91 or the front end of the rear chute. The mobile cloud platform 36 is provided on the guide rail 361. The mobile cloud platform 36 can translate on the guide rail 361. A rotary cylinder 38 is installed on the mobile cloud platform corresponding to the chute. A damping head 39 is provided on the rotating arm of the rotary cylinder; the rotary cylinder can move longitudinally on the mobile cloud platform.

[0050] The guide rail and the mobile platform are provided in a matching manner. For example, the guide rail 361 can be composed of two parallel screw rods and a guiding optical rod. The mobile platform is an electric slide table driven by a motor to rotate the nut. The nut rotates forward or backward to make the slide table move forward or backward; the guide rail 361 can also be composed of two parallel racks and a guiding optical rod. The mobile platform then correspondingly becomes an electric slide table formed by a gear meshing with the rack driven by a stepping motor or a servo motor. The gear rotates forward or backward to drive the slide table to move forward and backward along the rack. It can also be composed of two parallel guiding optical rods and a screw rod driven by a motor. The mobile platform is an ordinary slide table adapted to the screw rod. A guiding hole is provided on the slide table corresponding to the guiding optical rod, and a screw hole is provided corresponding to the screw rod. The motor drives the screw rod to rotate forward or backward, thereby driving the slide table to move forward or backward.

[0051] A lifting or rotating device is provided below the mobile platform corresponding to the rear chute; the damping head is installed on the lifting or rotating device; in this way, by controlling the lifting or rotating device, the damping head can be located in the rear chute to intercept the sheared material or outside the rear chute to release the sheared material; the rotating device can be a rotary cylinder, and the rotary cylinder drives the damping head to be located on the chute to damp the sheared material; or located outside the chute to release the sheared material.

[0052] In the fast measurement mode, when the rotating arm of the rotary cylinder is in the horizontal zero position state and the rotary cloud platform does not rotate, when the sheared material passes through the chute, the camera on the top of the rotary cloud platform performs visual recognition on the sheared material.

[0053] When in the precise measurement mode, the rotating arm of the rotating cylinder rotates 90 degrees to be perpendicular to the sheared material; the moving pan-tilt moves the rotating cylinder longitudinally according to the diameter of the sheared material to position the damping stopper appropriately.

[0054] When the sheared material passes through the front chute, its front part touches the damping stopper and stops; the rotating pan-tilt rotates, and the camera can change the angle to perform visual recognition on the sheared material; at the same time, the moving pan-tilt moves backward along the guide rail towards the tail of the rear chute, and the front part of the sheared material moves towards the tail of the rear chute along with the damping stopper; after the visual recognition is completed, the rotating cylinder rotates to make the swing arm rotate 90 degrees back to the zero position, and the sheared material is discharged through the tail end of the rear chute.

[0055] In the description of this specification, the specific features, structures, materials, or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0056] As described above, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
