Technical Field

[0001] The present invention belongs to the technical field of hot-dip galvanizing, and particularly relates to an angle steel feeding mechanism. Background Art

[0002] Chinese Patent CN 104711501B discloses "Angle Steel Galvanizing Numerical Control Hanging Line Device and Hanging Process", which galvanizes multiple angle steels by arranging them in a grate. It places the angle steels to be hung on a feeding rack, and raises one end of the feeding rack away from the feeding roller table, and the angle steels will slide into the angle steel positioning seat in sequence. Combining with the Figure 1 shown in this patent, the angle steels need to be placed at a specific angle. Manual placement will consume a large amount of time and cost, and a machine that can automatically place and adjust the positions of the angle steels uniformly is needed. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides an angle steel feeding mechanism that can automatically flip the angle steel to the target position to ensure uniform galvanizing of subsequent angle steels, and a feeding method for the angle steel feeding mechanism.

[0004] The technical solution adopted by the present invention to solve its technical problems is: an angle steel feeding mechanism, including:

[0005] A feeding track for transporting angle steels, having a space penetrating up and down inside;

[0006] An induction unit for sensing the placement position of the angle steel;

[0007] A first adjustment frame assembly and a second adjustment frame assembly, respectively having an avoidance position and a working position. When in the avoidance position, they are located below the feeding track. When in the working position, at least part of them is located above the feeding track to receive the angle steels on the feeding track and flip them;

[0008] The second adjustment frame assembly is located downstream of the first adjustment frame assembly, the first adjustment frame assembly is located downstream of the induction unit, and the induction unit is linked with the first adjustment frame assembly and the second adjustment frame assembly.

[0009] Further, the induction unit is used to sense that the angle steel is in a first placement position, a second placement position or a third placement position. When in the first placement position, the opening of the angle steel faces the head end of the feeding track. When in the second placement position, the opening of the angle steel faces the tail end of the feeding track. When in the third placement position, the opening of the angle steel faces downward.

[0010] Further, the first adjustment frame assembly at least includes a first shaft body and a first rotating frame connected to the first shaft body, and the first rotating frame has a first included angle; the second adjustment frame assembly at least includes a second shaft body and a second rotating frame connected to the second shaft body, and the second rotating frame has a second included angle, and the second included angle is smaller than the first included angle.

[0011] Furthermore, the first angle is adapted to the angle of the angle steel so that both side edges of the angle steel fit with the first rotating frame; the second angle is adapted to the angle formed by the side edge and the open end of the angle steel so that the single side edge of the angle steel fits with the second rotating frame, with the opening facing the inner side of the second rotating frame.

[0012] Furthermore, a conveying rack is provided at the head end of the conveying track, and an inclined conveyor belt is provided at the tail end of the conveying rack.

[0013] Furthermore, a first flipping mechanism is provided at the tail end of the feed track, which includes a first flipping axis and a first material rack. The first material rack is V-shaped and can rotate with the first flipping axis to rotate the angle steel from the third placement position with the opening facing downward to a position where both sides of the angle steel are inclined.

[0014] Furthermore, the sensing unit includes a bottom sensing part and a side sensing part. When the angle steel is in a first placement position, both the bottom sensing part and the side sensing part are triggered. When the angle steel is in a second placement position, the bottom sensing part is triggered. When the angle steel is in a third placement position, the sensing unit is not triggered.

[0015] The invention also discloses a feeding method of an angle steel feeding mechanism, comprising the following steps:

[0016] Place the angle steel on the conveyor track;

[0017] The sensing unit senses that the angle steel is in the first placement position, the first adjustment frame assembly is in the working position, and after receiving the angle steel, it is flipped to the second placement position, and the second adjustment frame assembly is in the working position, and after receiving the angle steel, it is flipped to the third placement position;

[0018] or,

[0019] The sensing unit senses that the angle steel is in the second placement position, the first adjustment frame assembly is in the avoidance position, and the second adjustment frame assembly is in the working position. After receiving the angle steel, it is turned over to the third placement position;

[0020] or,

[0021] The sensing unit senses that the angle steel is in the third placement position, and the first adjustment frame assembly and the second adjustment frame assembly are in the avoidance position.

[0022] Furthermore, the following steps are included: after the angle steel is in the third placement position, it enters the first flip mechanism and rotates with the first flip mechanism until both sides are tilted.

[0023] Furthermore, the angle steel is transferred to the conveyor track through the conveyor frame.

[0024] The beneficial effects of the present invention are as follows: 1) Through the cooperation of the first adjustment frame assembly and the second adjustment frame assembly, the angle steel in any placement position can be flipped to the target placement position, eliminating the need for manual material placement, with a high degree of automation and saving labor costs; 2) The first adjustment frame assembly and the second adjustment frame assembly can not only drive the angle steel to flip to switch its placement position, but also adjust the angle steel to be perpendicular to the transmission direction of the feeding track, eliminating the need for manual material alignment; 3) The induction unit is used to sense the placement position of the angle steel, which is linked with the first adjustment frame assembly and the second adjustment frame assembly, with accurate and effective judgment; 4) The angle steel finally undergoes galvanization in a state where both sides are inclined, ensuring good galvanization effect and avoiding uneven plating caused by the accumulation of zinc liquid at the corners.

Detailed Embodiment

[0033] To enable those skilled in the art to better understand the solution of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0034] As Figures 1-6 shown, an angle steel feeding mechanism includes a feeding track 81 for transporting angle steel 2, a sensing unit 82 for sensing the placement position of angle steel 2, and a first adjustment frame assembly 83 and a second adjustment frame assembly 84. The sensing unit 82, the first adjustment frame assembly 83, and the second adjustment frame assembly 84 are all arranged on the feeding track 81, and the second adjustment frame assembly 84 is located downstream of the first adjustment frame assembly 83, and the first adjustment frame assembly 83 is located downstream of the sensing unit 82. At the same time, the sensing unit 82 is linked with the first adjustment frame assembly 83 and the second adjustment frame assembly 84.

[0035] In this embodiment, the feeding track 81 is composed of two transmission chains. Therefore, there is space both above and below the feeding track 81, providing a space for the first adjustment frame assembly 83 and the second adjustment frame assembly 84 to rotate.

[0036] The first adjustment frame assembly 83 and the second adjustment frame assembly 84 respectively have an avoidance position and a working position. When in the avoidance position, the first adjustment frame assembly 83 and the second adjustment frame assembly 84 are located below the feeding track 81 so as not to interfere with the transmission of angle steel 2 on the feeding track 81; when in the working position, at least part of the first adjustment frame assembly 83 and the second adjustment frame assembly 84 is located above the feeding track 81 so as to receive the angle steel 2 on the feeding track 81 and flip it.

[0037] Therefore, the above-mentioned linkage between the sensing unit 82 and the first adjustment frame assembly 83 and the second adjustment frame assembly 84 means that the sensing unit 82 can sense the placement position of angle steel 2 on the feeding track 81 and judge whether the first adjustment frame assembly 83 and the second adjustment frame assembly 84 need to switch to the avoidance position or the working position.

[0038] More specifically, the sensing unit 82 is used to sense that the angle steel 2 is in the first placement position, the second placement position, or the third placement position. In the first placement position, the opening of the angle steel 2 faces the head end of the feeding track 81. As Figure 6 , Figure 7 shown, a in Figure 6 , Figure 7In this case, b is the second placement position of the angle steel 2. Here, the head end and the tail end are based on the transmission direction of the feeding track 81. The upstream is the head end, and the downstream is the tail end. When in the third placement position, the opening of the angle steel 2 faces downward, that is, it faces the feeding track 81, as Figure 6 , Figure 7 In this case, c is the third placement position of the angle steel 2. The first placement position a, the second placement position b, and the third placement position c here are not specific positions, but refer to the relative placement positions of the angle steel 2.

[0039] As Figure 2 shown, the first adjustment frame assembly 83 at least includes a first shaft body 831 and a first rotating frame 832 connected to the first shaft body 831. The first rotating frame 832 has a first included angle. The second adjustment frame assembly 84 at least includes a second shaft body 841 and a second rotating frame 842 connected to the second shaft body 841. The second rotating frame 842 has a second included angle, and the second included angle is smaller than the first included angle.

[0040] Specifically, the first included angle is adapted to the included angle of the angle steel 2, so that both sides of the angle steel 2 are in contact with the first rotating frame 832. The second included angle is adapted to the included angle formed by the side and the open end of the angle steel 2, so that the single side of the angle steel 2 is in contact with the second rotating frame 842, and the opening faces the inside of the second rotating frame 842. The adaptation here means that assuming the angle steel is a right angle steel, the first included angle is 90°, the included angle between the connecting line of its open end and the side is 45°, then the second included angle is 45°.

[0041] In order to ensure good galvanizing effect during the galvanizing process of the angle steel and avoid the accumulation of zinc liquid at the corners resulting in uneven coating, it is necessary for the angle steel to be galvanized with the opening facing the side. At this time, both sides of the angle steel are inclined, and the zinc liquid can smoothly slide down along the sides of the angle steel and will not accumulate at the corners. Therefore, it is necessary to rotate the angle steel to the state where both sides are inclined and then transport it outwards.

[0042] As Figure 6 , Figure 7 shown, a first flipping mechanism 11 is provided at the tail end of the feeding track 81. It includes a first flipping shaft 111 and a first rack 112. The first rack 112 is V-shaped and can rotate along with the first flipping shaft 111, thereby realizing the flipping of the angle steel 2. In the initial state, the opening of the first rack 112 faces the head end of the feeding track 81, and its included angle is adapted to the second included angle to receive the angle steel 2 with the opening facing downward, as Figure 6 shown; as Figure 7As shown, in the final state, the first material rack 112 rotates 90° counterclockwise, the opening of the first material rack 112 faces upward, and both sides of the angle steel 2 are tilted. There are multiple first material racks 112, and multiple first material racks 112 are connected to the first flip shaft 111, so that one first flip shaft 111 can drive multiple first material racks 112 to flip synchronously, and at this time, a stable connection is formed in the length direction of the angle steel 2. Of course, the structure of the first flip mechanism 11 can also be that each first material rack 112 is separately connected to the first flip shaft 111. In other words, the number of first material racks 112 and the first flip shaft 111 are the same. At the same time, multiple first material racks 112 are linked by the connecting rod 113 to ensure that all first material racks 112 can flip synchronously.

[0043] The head end of the feed track 81 is provided with a feed rack 85, and the tail end of the feed rack 85 is provided with an inclined conveyor belt 851. The angle steel 2 can be placed on the feed rack 85 at will, and transferred to the feed track 81 by the inclined conveyor belt 851, without the need for manual placement in a specific position. The setting of the inclined conveyor belt 851 can also adjust the angle steel 2 to be as perpendicular as possible to the transmission direction of the feed track 81, without the need for manual material adjustment.

[0044] like Figure 2 As shown, the sensing unit 82 includes a bottom sensing member 821 and a side sensing member 822. When the angle steel 2 is in the first placement position, since the two side edges of the angle steel 2 touch the bottom sensing member 821 and the side sensing member 822 respectively, or in other words, the distances to the bottom sensing member 821 and the side sensing member 822 are very close and the triggering area is large, the bottom sensing member 821 and the side sensing member 822 are both triggered; when the angle steel 2 is in the second placement position, one side edge of the angle steel 2 triggers the bottom sensing member 821, and the other side edge is far away from the side sensing member 822 and will not trigger the side sensing member 822; when the angle steel 2 is in the third placement position, the two side edges are far away from the bottom sensing member 821 and the side sensing member 822, and the triggering area is small, and the sensing unit 82 is not triggered.

[0045] A feeding method of an angle steel feeding mechanism comprises the following steps:

[0046] The angle steels 2 are randomly placed on the conveyor rack 85. There is no need for manual material placement. The bundled angle steels 2 are mechanically untied and placed on the conveyor rack 85. The conveyor rack 85 is started for transmission, and the angle steels 2 fall on the head end of the conveyor track 81 through the inclined conveyor belt 851.

[0047] The sensing unit 82 senses that the angle steel 2 is in the first placement position a, sends a signal to the first adjustment frame assembly 83, so that the first adjustment frame assembly 83 is in the working position, and drives the angle steel 2 to be flipped by 90° after passing through the first adjustment frame assembly 83, so that the angle steel 2 is in the second placement position b; the sensing unit 82 also needs to send a signal to the second adjustment frame assembly 84, so that the second adjustment frame assembly 84 is in the working position, so that the angle steel 2 in the second placement position b enters the second adjustment frame assembly 84 after being transported by the feeding track 81, and is driven by it to be flipped by 90°, so that the angle steel 2 is in the third placement position c and continues to be transported to the end of the feeding track 81;

[0048] Or,

[0049] The sensing unit 82 senses that the angle steel 2 is in the second placement position b, sends a signal to the first adjustment frame assembly 83, so that the first adjustment frame assembly 83 is in the avoidance position, as Figure 3 shown, the angle steel 2 continues to move along with the feeding track 81 and passes over the first adjustment frame assembly 83; the sensing unit 82 also needs to send a signal to the second adjustment frame assembly 84, so that the second adjustment frame assembly 84 is in the working position, so that the angle steel 2 in the second placement position b enters the second adjustment frame assembly 84 after being transported by the feeding track 81, and is driven by it to be flipped by 90°, so that the angle steel 2 is in the third placement position c and continues to be transported to the end of the feeding track 81;

[0050] Or,

[0051] The sensing unit 82 senses that the angle steel 2 is in the third placement position c, sends signals to the first adjustment frame assembly 83 and the second adjustment frame assembly 84, so that they are both in the avoidance position, and the angle steel 2 does not need to be flipped and directly moves to the end along with the feeding track 81;

[0052] The angle steel 2 in the third placement position c enters the first flipping mechanism 11, and the first flipping shaft 111 drives the first material rack 112 to rotate by 90°, so that both sides of the angle steel 2 are inclined.

[0053] The above specific embodiments are used to explain and illustrate the present invention, rather than limiting the present invention. Within the spirit and scope of the protection of the claims of the present invention, any modification and change made to the present invention fall within the protection scope of the present invention.
