Description

Technical Field

[0001] This invention relates to the field of steel profile sorting and feeding technology, and more specifically, to steel profile sorting mechanisms and galvanizing lines. Background Technology

[0002] U-shaped steel is a common type of special-shaped steel. To facilitate transportation and storage, it is usually stacked in multiple rectangular layers, with the opening directions of the U-shaped steel in each adjacent layer staggered and opposite. After the galvanizing process is completed, these U-shaped steels need to be reorganized, oriented, and packaged for subsequent warehousing or transportation. Currently, this sorting and packaging process mainly relies on manual operation. Operators need to manually adjust the posture of each U-shaped steel on the conveyor line (to make it perpendicular to the conveying direction) and identify and unify the opening orientation one by one. This manual material handling method has problems such as high labor intensity, low work efficiency, and easy to make mistakes in judging the opening direction or improper posture adjustment due to fatigue, which makes it difficult to meet the needs of automated production lines for efficient and accurate sorting. Summary of the Invention

[0003] To address the above deficiencies, this invention provides a steel profile feeding mechanism and a galvanizing line, thereby solving the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Steel profile handling mechanism and galvanizing line, including: Conveyor frame, used for conveying U-shaped steel; The first adjustment unit includes a cylinder, an expansion airbag, a positioning rod, and an adjustment rod; the axial direction of the positioning rod and the adjustment rod is perpendicular to the conveying direction of the conveyor frame. Cylinder 1 is used to drive the positioning rod and the inflatable airbag to move, so that the inflatable airbag is inserted into one end of the U-shaped steel and inflates, forming the first positioning point at that end of the U-shaped steel; The adjusting rod is slidably mounted on the positioning rod, and the side wall of the adjusting rod is used to contact one end of the U-shaped steel to form a second positioning point; As the adjusting rod slides along the positioning rod, the second positioning point moves relative to the first positioning point, causing the axial direction of the U-shaped steel to gradually become perpendicular to the conveying direction of the conveyor frame. The second adjustment unit includes a hydraulic rod, a rotating tube, and a second cylinder. The hydraulic rod is used to drive the rotating tube to be sleeved on the end of the U-shaped steel. The second cylinder includes a first cylinder, a second cylinder, a third cylinder, and a fourth cylinder, which are respectively set on the rotating tube corresponding to the upper, lower, left, and right sides of the U-shaped steel. Cylinder 2 is used to extend to clamp the U-shaped steel. When the U-shaped steel has an opening on one side, the extension of cylinder 2 corresponding to the opening position is greater than the extension of the other three cylinders 2. The opening orientation of the U-shaped steel is determined by comparing the extension of each cylinder 2. The rotating tube is controlled to rotate so that the opening of the U-shaped steel faces the specified direction.

[0005] Furthermore, the first adjustment unit also includes a base on one side of the conveyor frame, a cylinder is mounted on the base, a positioning rod is mounted on the telescopic end of the cylinder, an inflatable airbag is mounted on one end of the positioning rod, the positioning rod is hollow, an air supply pipe is provided at one end of the inflatable airbag, and the air supply pipe passes through the positioning rod; an auxiliary wheel is mounted on the end of the positioning rod away from the cylinder, the auxiliary wheel is close to the inner wall of the adjustment rod, a rack is provided on the side wall of the positioning rod, a drive motor is mounted on the inner wall of the adjustment rod, and the output end of the drive motor meshes with the rack.

[0006] Furthermore, one end of the adjusting rod is equipped with guide wheels, and there are four guide wheels. The guide wheels move relative to the U-shaped steel to correct the position of the U-shaped steel. The positioning rod and the adjusting rod have rectangular cross-sections, and there are four guide wheels respectively located on the four walls of the adjusting rod.

[0007] Furthermore, a rotary motor is installed at the telescopic end of the hydraulic rod, a rotating tube is installed at the rotating end of the rotary motor, and a pad is installed at the telescopic end of the cylinder.

[0008] Furthermore, a lifting rod is provided at one end of the conveyor frame, and a vibrating table is installed at the telescopic end of the lifting rod.

[0009] Furthermore, a support is provided at the other end of the conveyor frame, a pneumatic rod is installed at one end of the support, a baffle is installed at the telescopic end of the pneumatic rod, a temporary storage area is formed on one side of the baffle, and a second baffle is installed on the support, a temporary storage area is formed on one side of the second baffle.

[0010] By temporarily storing U-shaped steel with the same opening orientation in different areas (such as temporary storage area one and temporary storage area two), it is easier for the external robotic arm to grasp and stack them in an orderly manner, thereby realizing alternating stacking of positive and negative layers, which greatly facilitates the final packaging operation.

[0011] Furthermore, a sensor is provided above the first adjustment unit; the first adjustment unit has one sensor located at one end of the U-shaped steel, and the second adjustment unit has a pair of sensors located at both ends of the U-shaped steel.

[0012] Furthermore, the steel profile feeding mechanism is located at the discharge end of the galvanizing line.

[0013] The beneficial effects of this invention are as follows: by setting up a first adjustment unit, an expansion airbag driven by a cylinder is inserted into the end of the U-shaped steel and expands to form a first positioning point, which is then combined with an adjustment rod that can slide along the positioning rod to form a second positioning point; as the adjustment rod slides, the second positioning point moves relative to the first positioning point, which can gradually push the U-shaped steel, which is placed at any angle on the conveyor frame, to be straightened so that its axial direction is precisely perpendicular to the conveying direction; this process is completed automatically, which significantly improves the straightening efficiency and consistency and avoids the errors of manual adjustment; By setting up a second adjustment unit, the ends of the U-shaped steel are clamped by cylinders in four directions (up, down, left, and right). The control system can accurately determine the orientation of the opening of the U-shaped steel by comparing the extension of each cylinder. Then, the control rotating tube drives the U-shaped steel to rotate, so that its opening faces the designated direction (such as up or down). This completely replaces the manual identification and flipping process, greatly reduces labor intensity, and creates conditions for subsequent automated stacking and packaging.

Detailed Implementation

[0015] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] This application provides a steel profile handling mechanism and a galvanizing line; please refer to the following: Figures 1-6 :include: Conveyor frame 1 is used to convey U-shaped steel. The first adjustment unit includes a cylinder 2, an inflatable airbag 3, a positioning rod 4, and an adjustment rod 5; the axial direction of the positioning rod 4 and the adjustment rod 5 is perpendicular to the conveying direction of the conveyor frame 1. Cylinder 2 is used to drive the positioning rod 4 and the inflatable airbag 3 to move, so that the inflatable airbag 3 is inserted into one end of the U-shaped steel and inflates, forming the first positioning point 6 at that end of the U-shaped steel; The adjusting rod 5 is slidably mounted on the positioning rod 4, and the side wall of the adjusting rod 5 is used to contact one end of the U-shaped steel to form a second positioning point 7; As the adjusting rod 5 slides along the positioning rod 4, the second positioning point 7 moves relative to the first positioning point 6, so that the axial direction of the U-shaped steel gradually becomes perpendicular to the conveying direction of the conveying frame 1. The second adjustment unit includes a hydraulic rod 8, a rotating tube 9, and a second cylinder 10; the hydraulic rod 8 is used to drive the rotating tube 9 to be sleeved on the end of the U-shaped steel; the second cylinder 10 includes a first cylinder 101, a second cylinder 102, a third cylinder 103, and a fourth cylinder 104, which are respectively set on the rotating tube 9 corresponding to the upper side, lower side, left side, and right side of the U-shaped steel. Cylinder 2 10 is used to extend to clamp the U-shaped steel; when the U-shaped steel has an opening on one side, the extension of cylinder 2 10 corresponding to the opening position is greater than the extension of the other three cylinders 2 10. The opening orientation of the U-shaped steel is determined by comparing the extension of each cylinder 2 10; and the rotating tube 9 is controlled to rotate so that the opening of the U-shaped steel faces the specified direction.

[0017] In practical applications, this application is used in the galvanizing process of U-shaped steel. After galvanizing, the U-shaped steel is scattered on the conveyor rack 1, which is not conducive to the subsequent sorting and packaging of the U-shaped steel. When the U-shaped steel moves to the position aligned with the first adjustment unit, the control cylinder 2 extends, causing the expansion airbag 3 to insert into one end of the U-shaped steel and expand, forming the first positioning point 6 at that end of the U-shaped steel. like Figure 6 As shown, the control adjustment rod 5 then slides towards the U-shaped steel, and the side wall of the adjustment rod 5 is used to contact one end of the U-shaped steel to form a second positioning point 7; as the adjustment rod 5 slides along the positioning rod 4, the second positioning point 7 moves relative to the first positioning point 6, so that the axial direction of the inclined U-shaped steel gradually becomes perpendicular to the conveying direction of the conveying frame 1. Subsequently, through the conveyor frame 1, when the U-shaped steel moves to the position aligned with the second adjustment unit, the hydraulic rod 8 extends, driving the rotating tube 9 to be sleeved on the end of the U-shaped steel, controlling the first cylinder 101, the second cylinder 102, the third cylinder 103 and the fourth cylinder 104 to extend synchronously. When the U-shaped steel has an opening on one side, the extension of cylinder 2 10 corresponding to the opening position is greater than the extension of the other three cylinders 2 10. The opening orientation of the U-shaped steel is determined by comparing the extension of each cylinder 2 10. The rotating tube 9 is controlled to rotate so that the opening of the U-shaped steel faces the specified direction. When the U-shaped steel needs to face upward, cylinder 2 10 with the larger extension faces upward; when the U-shaped steel needs to face downward, cylinder 2 10 with the larger extension faces downward. This facilitates later sorting, arrangement, and packaging.

[0018] Reference Figure 1 , Figure 2 and Figure 3 The first adjustment unit also includes a base 21 located on one side of the conveyor frame 1, a cylinder 2 mounted on the base 21, a positioning rod 4 mounted on the telescopic end of the cylinder 2, an inflatable airbag 3 mounted on one end of the positioning rod 4, the positioning rod 4 being hollow, an air supply pipe 22 being provided at one end of the inflatable airbag 3, the air supply pipe 22 passing through the positioning rod 4; an auxiliary wheel 23 being mounted on the end of the positioning rod 4 away from the cylinder 2, the auxiliary wheel 23 being close to the inner wall of the adjustment rod 5, a rack 24 being provided on the side wall of the positioning rod 4, a drive motor 25 being mounted on the inner wall of the adjustment rod 5, the output end of the drive motor 25 meshing with the rack 24.

[0019] In practical applications, the base 21 provides stable support for the cylinder 2 and the positioning rod 4. The air supply pipe 22 is installed at the output end of the external air compressor. When the air supply pipe 22 is supplied with air, the expansion bladder 3 expands. When the air supply pipe 22 is supplied with air, the expansion bladder 3 contracts. The expansion bladder 3 is inserted into the U-shaped steel and expands, preventing the U-shaped steel from moving axially while allowing the U-shaped steel to swing slightly to achieve position adjustment. The drive motor 25 rotates, causing the adjusting rod 5 and the positioning rod 4 to move relative to each other. One end of the adjusting rod 5 contacts the U-shaped steel, causing the U-shaped steel to gradually straighten.

[0020] The adjustment rod 5 moves stably by means of the auxiliary wheel 23 and the drive motor 25 meshing with the rack 24.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 One end of the adjusting rod 5 is equipped with a guide wheel 31. There are four guide wheels 31. The guide wheels 31 move relative to the U-shaped steel to correct the position of the U-shaped steel. The positioning rod 4 and the adjusting rod 5 have rectangular cross sections. There are four guide wheels 31 respectively located on the four walls of the adjusting rod 5.

[0022] In practical applications, the contact between the guide wheel 31 and the U-shaped steel makes the adjustment of the U-shaped steel smoother.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The hydraulic rod 8 has a rotary motor 41 installed at its telescopic end, the rotating tube 9 is installed at the rotating end of the rotary motor 41, and the cylinder 2 10 has a pad 42 installed at its telescopic end.

[0024] In practical applications, this application includes a controller to determine the opening direction of the U-shaped steel. Then, the rotating motor 41 rotates to drive the rotating tube 9 and the U-shaped steel to rotate, so that the opening of the U-shaped steel rotates to the specified direction; the pad 42 enables the cylinder 10 to better clamp the U-shaped steel.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The conveyor frame 1 is equipped with a lifting rod 51 at one end, and a vibrating table 52 is installed at the telescopic end of the lifting rod 51.

[0026] In practical applications, when the lifting rod 51 rises, it drives the vibrating table 52 to rise, simultaneously causing the U-shaped steel to detach from the conveyor frame 1. The vibrating table 52 then vibrates, promoting the spreading of the U-shaped steel.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The other end of the conveyor frame 1 is provided with a support 61. A pneumatic rod 62 is installed at one end of the support 61. A baffle 63 is installed at the telescopic end of the pneumatic rod 62. A temporary storage area 64 is formed on the side of the baffle 63. A second baffle 65 is installed on the support 61. A second temporary storage area 66 is formed on one side of the baffle 65.

[0028] In practical applications, the pneumatic rod 62 extends to raise the baffle 63, which can prevent the U-shaped steel with the adjusted direction from moving and temporarily store it in the position of the temporary storage area 64; the baffle 65 has the same effect; the opening of the U-shaped steel in the temporary storage area 64 faces upward, and the opening of the U-shaped steel in the temporary storage area 66 faces downward, which facilitates orderly transportation by the external robotic arm.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The first adjustment unit is equipped with a sensor 71 above it; the first adjustment unit has one sensor located at one end of the U-shaped steel, and the second adjustment unit has a pair of sensors located at both ends of the U-shaped steel.

[0030] In practical applications, the sensor 71 facilitates the alignment of the U-shaped steel with the first adjustment unit; the steel feeding mechanism is located at the discharge end of the galvanizing line.
