Description

Technical Field

[0001] This invention relates to the field of production equipment, and in particular to a front-row steel stacking device for rail steel. Background Technology

[0002] Rail steel is a specialized type of steel used to manufacture rails for locomotives, cranes, and other vehicles. According to Chinese national standards and the standards of the Ministry of Metallurgical Industry, rails are classified into railway rails, light rails, conductive rails, and crane rails, etc.

[0003] During the production and processing of rail steel, a conveyor chain is usually used to transport the shaped rail steel out of the manufacturing station, and then the rail steel is stacked in sequence for storage or transportation. Because the rail steel has an irregular shape, that is, the upper end of the rail steel is narrow and the lower end is wide, the rail steel cannot be freely and easily placed against each other. Otherwise, when the second row of rail steel is stacked upside down on the first row of rail steel, the narrow end of the second row of rail steel may not be able to be inserted into the spacing of the first row of rail steel, making it impossible for the rail steel to be stacked neatly.

[0004] Currently, the rail steel is usually stacked manually by cranes or robotic arms to arrange the upright rail steel at equal intervals. Then, the second row of inverted rail steel is inserted into the intervals of the first row of upright rail steel and stacked in this manner. This process is repeated. This method is time-consuming, and manual operation can easily lead to differences in the spacing between the rail steel, making it impossible to stack the rail steel neatly and tightly. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a steel palletizing device for front-row steel stacking, comprising a fixed base, a pushing device, a placing device, and a conveyor chain. A first fixed frame and a second fixed frame are arranged parallel to each other on the fixed base. A first slide rail is provided on the first fixed frame, and a second slide rail is provided on the second fixed frame. The pushing device is mounted on the second slide rail, and the placing device is mounted on the first slide rail. The conveyor chain is arranged side-by-side with the pushing device and the placing device.

[0006] Preferably, the pushing device includes a second bracket, a second cylinder, and a transverse frame. The second bracket is configured with a W-shaped structure, and multiple second pulleys are provided on the left and right side walls of the second bracket. The second pulleys are installed in the second slide rail. The front end of the second cylinder is fixed at the middle position of the second bracket, and the rear end of the second cylinder is fixed on the fixed base. The transverse frame is installed on the upper end of the second bracket, and a sliding groove is provided on the transverse frame.

The bottom of the push plate is set in the sliding groove, and the bottom of the baffle is fixed on the transverse frame.

[0007] Preferably, the placement device includes a first support, a first cylinder, and a placement rack. The first support is configured with a W-shaped structure.

[0017] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0018] Unless otherwise stated, any feature in this specification may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is merely one example of a series of equivalent or similar features.

[0019] like Figure 1 , 2 As shown in Figure 5, a front-row steel stacking device for rail steel includes a fixed base 1, a pushing device 2, a placing device, and a conveyor chain 4. A first fixed frame 17 and a second fixed frame 19 are arranged in parallel on the fixed base 1. A first slide rail 18 is arranged on the first fixed frame 17, and a second slide rail 20 is arranged on the second fixed frame 19. The pushing device 2 is installed on the second slide rail 20, and the placing device is installed on the first slide rail 18. The conveyor chain 4 is arranged side by side with the pushing device 2 and the placing device.

[0020] like Figure 1 , 2 As shown in Figures 1 and 3, the pushing device 2 includes a second support 5, a second cylinder 7, and a transverse frame 8. The second support 5 is configured with a W-shaped structure. Multiple second pulleys 6 are provided on the left and right side walls of the second support 5. The second pulleys 6 are installed in the second slide rail 20. The front end of the second cylinder 7 is fixed at the middle position of the second support 5, and the rear end of the second cylinder 7 is fixed on the fixed base 1. The transverse frame 8 is installed on the upper end of the second support 5. A slide groove 9 is provided on the transverse frame 8. A lead screw 10 is provided above the slide groove 9. A servo motor 13 is provided at the right end of the lead screw 10. The servo motor 13 is installed on the transverse frame 8. A push plate 11 and a baffle 12 are respectively sleeved on the lead screw 10 near the left and right ends. The bottom of the push plate 11 is set in the slide groove 9, and the bottom of the baffle 12 is fixed on the transverse frame 8.

[0021] like Figure 1 , 2As shown in Figure 4, the placement device includes a first support 14, a first cylinder 16, and a placement rack 3. The first support 14 is configured with a W-shaped structure. Multiple first pulleys 15 are provided on the left and right side walls of the first support 14. The first pulleys 15 are installed in the first slide rail 18. The front end of the first cylinder 16 is fixed at the middle position of the first support 14, and the rear end of the first cylinder 16 is fixed on the fixed base 1. The placement rack 3 is installed on the upper end of the first support 14.

[0022] like Figure 2 , 4 As shown, a sensor 21 is installed at the front end of the placement rack 3, and an inclined surface is provided at the front end of the placement rack 3.

[0023] like Figure 2 As shown, a palletizing robot can be installed above the conveyor chain 4 to facilitate the handling of the rail steel.

[0024] During use, the first cylinder 16 pushes the first bracket 14 upward, causing the first pulley 15 on the first bracket 14 to move in the first slide rail 18, further driving the placement frame 3 upward, so that the placement frame 3 extends out of the gap of the conveyor chain 4 until the horizontal plane of the upper end of the placement frame 3 is higher than the horizontal plane of the conveyor chain 4. At this time, the chain surface of the conveyor chain 4 is higher than the lowest position of the inclined surface at the front end of the placement frame 3. Then, the rail steel is conveyed backward by the conveyor chain 4. When the rail steel reaches the position of the placement frame 3, the front end of the placement frame 3... Sensor 21 detects the rail steel, thereby controlling the second cylinder 7 to push the second bracket 5 upwards. This causes the second pulley 6 on the second bracket 5 to move in the second slide rail 20, further driving the transverse frame 8 upwards until the push plate 11 and the baffle 12 extend out of the gap in the conveyor chain 4. After the push plate 11 and the baffle 12 have fully extended out of the gap in the conveyor chain 4, the servo motor 13 drives the lead screw 10 to rotate, thereby driving the push plate 11 to move backwards by a preset distance, and thus driving the rail steel backwards. The movement continues until the rail steel abuts against the baffle 12, at which point the push plate 11 stops moving backward and is reset by the servo motor 13. Then, the second cylinder 7 pulls down the second bracket 5, resetting the transverse frame 8 and its push plate 11 and baffle 12. After the pushing device 2 has reset, the first cylinder 16 continues to hold the placement frame 3 in place, while the conveyor chain 4 continues to transport the rail steel backward. When the second rail steel reaches the bottom of the placement frame 3, the sensor 21 detects the rail steel again, thus controlling... The second cylinder 7 pushes the second support 5 upward, causing the transverse frame 8 on the second support 5 and its push plate 11 and baffle 12 to move upward and extend out from the gap of the conveyor chain 4. Then, the servo motor 13 drives the lead screw 10 to rotate, thereby driving the push plate 11 to move backward according to a preset moving distance, and then driving the rail steel to move backward until the second rail steel moves to a certain distance from the first rail steel and stops moving backward. In this way, the first row of rail steel placed in the forward position is arranged at equal intervals.

[0025] After the first row of rail steel is placed upright, the first cylinder 16 can pull the placement frame 3 downwards, causing the placement frame 3 and the several rail steels placed on it to move downwards. When the horizontal plane of the upper end of the placement frame 3 is lower than the horizontal plane of the conveyor chain 4, the several rail steels placed on the conveyor chain 4 will be placed on the conveyor chain 4 and continue to be conveyed and stacked. Alternatively, the first cylinder 16 can keep the placement frame 3 and the several rail steels placed on it in a fixed position, and the stacking robot can pick up and transport the several rail steels placed on it to the stacking position for stacking. After the rail steels on the placement frame 3 are taken away by the stacking robot, the first cylinder 16 pulls the placement frame 3 to reset, and this process is repeated.

[0026] The groove 9 is designed to make the push plate 11 move more stably and less prone to shaking during the forward and backward movement of the push plate 11.

[0027] The first support 14 and the second support 5 are configured with a W-shaped structure, which enables the first pulley 15 on the left and right side walls of the first support 14 and the second pulley 6 on the left and right side walls of the second support 5 to move synchronously and stably in the first slide rail 18 and the second slide rail 20 when the first cylinder 16 and the second cylinder 7 push the first support 14 and the second support 5 to move up and down.

[0028] The front end of the placement rack 3 is provided with an inclined surface, which makes it easier for the push plate 11 to push the rail steel onto the placement rack 3, and makes it less likely for the steel to get stuck or the rail steel to tip over.

[0029] The beneficial effects of this invention are: the invention has a reasonable structural design and is easy to use. By setting up a liftable pushing device and a placement frame, it is easy to arrange the rail steel conveyed on the conveyor chain at equal intervals, which facilitates the rapid and neat stacking of the rail steel, improves the production efficiency of rail steel, and also saves manpower.

[0030] This invention is not limited to the specific embodiments described above. The invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
