[0002] Rail steel is a specialized steel used to manufacture tracks for locomotives, cranes, etc. Rails are divided into railway rails, light rails, conductive rails, crane rails, etc. according to Chinese national standards and the standards of the Ministry of Metallurgical Industry.

[0003] In the production and processing of rail steel, conveyor chains are usually used to transport the formed rail steel out of the manufacturing station, and then the rail steel is stacked in sequence for easy storage or transportation. Since the rail steel has an irregular structure as a whole, 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 in sequence. 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 cannot be inserted into the spacing of the first row of rail steel, making it impossible to stack the rail steel normally and neatly.

[0004] At present, the stacking of rail steel is usually done by manually controlling a crane or a manipulator to arrange the upright rail steels at equal intervals, and then insert the second row of inverted rail steels into the intervals of the first row of upright rail steels for stacking, and repeat this process. This method is time-consuming and manual operation of steel arrangement is prone to differences in the intervals between the rail steels, making it impossible to stack the rail steels neatly and tightly.

[0013] like Figure 1 , 2 , 5 and a device for front row steel of rail steel palletizing, comprising a fixed seat 1, a pushing device 2, a placing device and a conveying chain 4, wherein a first fixed frame 17 and a second fixed frame 19 are arranged in parallel on the fixed seat 1, a first slide rail 18 is arranged on the first fixed frame 17, 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, the placing device is installed on the first slide rail 18, and the conveying chain 4 is arranged side by side with the pushing device 2 and the placing device.

[0014] like Figure 1 , 2 As shown in Figure 3, the pushing device 2 includes a second bracket 5, a second cylinder 7 and a transverse frame 8. The second bracket 5 is set to a W-shaped structure. A plurality of second pulleys 6 are arranged on the left and right side walls of the second bracket 5. The second pulley 6 is installed in the second slide rail 20. The front end of the second cylinder 7 is fixed at the middle position of the second bracket 5, and the rear end of the second cylinder 7 is fixed on the fixed seat 1. The transverse frame 8 is installed at the upper end of the second bracket 5. A slide groove 9 is arranged on the transverse frame 8. A screw rod 10 is arranged above the slide groove 9. A servo motor 13 is arranged on the right end of the screw rod 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 screw rod 10 near the left and right ends. The bottom of the push plate 11 is arranged in the slide groove 9, and the bottom of the baffle 12 is fixed on the transverse frame 8.

[0015] like Figure 1 , 2As shown in Figure 4, the placement device includes a first bracket 14, a first cylinder 16 and a placement rack 3. The first bracket 14 is configured as a W-shaped structure. A plurality of first pulleys 15 are provided on the left and right side walls of the first bracket 14. The first pulley 15 is installed in a first slide rail 18. The front end of the first cylinder 16 is fixed at the middle position of the first bracket 14, and the rear end of the first cylinder 16 is fixed on the fixed seat 1. The placement rack 3 is installed at the upper end of the first bracket 14.

[0016] 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.

[0017] like Figure 2 As shown, a stacking robot can be arranged above the conveyor chain 4 to facilitate the handling of the rail steel.

[0018] During use, the first cylinder 16 lifts the first bracket 14 upward, so that the first pulley 15 on the first bracket 14 moves in the first slide rail 18, and further drives the placement rack 3 to move upward, so that the placement rack 3 extends from the gap of the conveyor chain 4 until the horizontal plane of the upper end surface of the placement rack 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 of the front end of the placement rack 3. Then, the rail steel is transported backward by the conveyor chain 4. When the rail steel reaches the position of the placement rack 3, the front end of the placement rack 3 The sensor 21 senses the rail steel, thereby controlling the second cylinder 7 to lift the second bracket 5 upward, so that the second pulley 6 on the second bracket 5 moves in the second slide rail 20, further driving the transverse frame 8 to move upward until the push plate 11 and the baffle 12 extend from the gap of the conveyor chain 4. After the push plate 11 and the baffle 12 extend from the gap of the conveyor chain 4, the servo motor 13 drives the screw rod 10 to rotate, thereby driving the push plate 11 to move backward according to the preset moving distance, thereby driving the rail steel backward. The push plate 11 stops moving backwards until the rail steel contacts the baffle plate 12, and the push plate 11 is reset by the servo motor 13. Then the second bracket 5 is pulled downwards by the second cylinder 7, so that the transverse frame 8 and the push plate 11 and the baffle plate 12 thereon are reset. After the pushing device 2 is reset, the first cylinder 16 still lifts the placement rack 3 to keep the position unchanged, and the conveyor chain 4 continues to transport the rail steel backwards. When the second rail steel reaches the position of the bottom placement rack 3, the sensor 21 senses the rail steel again, thereby controlling the The second cylinder 7 is controlled to lift the second bracket 5 upward, so that the transverse frame 8 on the second bracket 5 and the push plate 11 and the baffle 12 thereon move upward and extend out from the gap of the conveyor chain 4, and 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, thereby repeatedly arranging the first row of rail steels placed in the forward direction at equal intervals.

[0019] After the first row of rail steels to be placed in the forward direction is completed, the placement rack 3 can be pulled downward by the first cylinder 16, so that the placement rack 3 and the several rail steels with steel arranged thereon can move downward. When the horizontal plane of the upper end surface of the placement rack 3 is lower than the horizontal plane of the conveyor chain 4, the several rail steels with steel arranged thereon will be placed on the conveyor chain 4 and continue to be conveyed backward and stacked; or the first cylinder 16 still lifts the placement rack 3 and the several rail steels with steel arranged thereon to keep their positions unchanged, and the several rail steels with steel arranged thereon are sucked up and transported to the stacking position for stacking by the stacking robot. After the rail steels on the placement rack 3 are transported away by the stacking robot, the first cylinder 16 pulls the placement rack 3 to reset, and this sequence is repeated.

[0020] The arrangement of the slide groove 9 can make the push plate 11 move more stably and less likely to shake during the forward and backward movement of the push plate 11 .

[0021] The first bracket 14 and the second bracket 5 are configured as a W-shaped structure, so that when the first cylinder 16 and the second cylinder 7 push the first bracket 14 and the second bracket 5 to move up and down, the first pulley 15 on the left and right side walls of the first bracket 14 and the second pulley 6 on the left and right side walls of the second bracket 5 can move synchronously and stably in the first slide rail 18 and the second slide rail 20.

[0022] The front end of the placement rack 3 is provided with an inclined surface, which can make it smoother when the push plate 11 pushes the rail steel onto the placement rack 3, and is less likely to cause the steel to get stuck or the rail steel to tip over.

[0023] The beneficial effects of the present invention are as follows: the present invention has a reasonable structural design and is easy to use. By providing a liftable pushing device and a placement rack, the rail steel transported on the conveyor chain can be arranged at equal intervals, thereby facilitating the subsequent rapid and neat stacking of the rail steel, thereby improving the production efficiency of the rail steel and saving manpower.

[0024] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
