[0002] Precast angle steel is widely used in port machinery, engineering machinery, bridges, and building steel structures. For example, in port machinery, precast angle steel mainly includes structural angle steel 1 used for reinforcing box-type panels and railing posts 2 used for ladder platforms and other accessories of quay cranes. Figure 1 (As shown). The raw material angle steel is the processing raw material for prefabricated angle steel. The raw material angle steel is generally 6m-12m in length and weighs 200kg per piece.

[0003] Traditional port machinery prefabricated angle steel manufacturing process uses punch press + mold, which requires multiple processes. Moreover, the incoming posture of the raw material angle steel is not certain, and manual loading, unloading, posture adjustment and sorting are required each time.

[0044] Figure 2 A schematic diagram of multiple raw material angle steels 20 in the incoming material state is shown. Figure 3 This diagram shows the overall structure of the prefabricated angle steel automated production line 10 provided in this embodiment. Figure 4 A schematic diagram of the automatic feeding device 100 provided in this embodiment is shown. Please refer to the attached diagram. Figures 2-4 This embodiment provides an automatic feeding device 100 and a precast angle steel automatic production line 10. The precast angle steel automatic production line 10 includes the automatic feeding device 100, which enables automatic feeding of the precast angle steel automatic production line 10. The raw material angle steel 20 includes a first side 21 and a second side 22. Both the first side 21 and the second side 22 are elongated plate-like structures. One end of the width direction of the first side 21 is fixedly connected to one end of the width direction of the short side arm to form an angle end 23. The other end of the width direction of the first side 21 and the other end of the width direction of the second side 22 are free ends. These two free ends are spaced apart, thus forming an angled structure through the first side 21 and the second side 22. Generally, the raw material angle steel 20 is a one-piece molded part.

[0045] The automatic feeding device 100 and the precast angle steel automatic production line 10 provided in this embodiment are further described below:

[0046] Please refer to Figure 4 This embodiment provides an automatic feeding structure, which includes a frame 110. The frame 110 is generally square and has a length direction A and a width direction B. A conveyor 111 is provided at one end of the frame 110 in the width direction, and the conveyor 111 holds items such as... Figure 2 The diagram shows multiple raw material angle steels 20 in the incoming material state, with the length direction of the multiple raw material angle steels 20 arranged along the length direction of the frame 110. Furthermore, the conveyor 111 is also used to convey the raw material angle steels 20 along the width direction B. In other words, the "conveyor direction" mentioned later in this embodiment is the forward direction of the width direction of the frame 110.

[0047] Optionally, the conveyor 111 is a conveyor chain, which drives the raw material angle steel 20 to reciprocate in the width direction B as the conveyor chain rotates forward and reverses. Furthermore, since the raw material angle steel 20 is relatively long, to ensure stable conveying of the raw material angle steel 20 by the conveyor 111, multiple conveyor components 111 are spaced apart along the length direction of the frame 110. These multiple conveyor components 111 simultaneously support different positions of the raw material angle steel 20 along its length and drive it to move in the width direction. Similarly, the number of magnetic clamping structures 120 and floating support components 151 mentioned later can also be set to multiple components distributed along the length direction of the raw material angle steel 20 (i.e., the length direction A of the frame 110).

[0048] Furthermore, a feeding rack 112 is provided on one side of the frame 110 in the width direction. The feeding rack 112 is located behind the conveyor 111 and is used to store the raw material angle steel 20 to be processed. For example, when processing structural angle steel, the raw material angle steel 20 for processing railing posts can be placed on the feeding rack 112. At the same time, the feeding rack 112 is set open towards the conveyor 111 without a stop structure, which facilitates the transfer of the raw material angle steel 20 from the feeding rack 112 to the conveyor 111.

[0049] It should be noted that in the description of this embodiment, if the terms "front side" and "rear side" appear, then the front side and rear side are two opposite sides along the conveying direction.

[0050] Figure 5 This diagram illustrates the structure of the magnetic clamp structure 120 in the automatic feeding device 100 provided in this embodiment when it magnetically attracts the raw material angle steel 20. Figure 6 This diagram illustrates the structure of the magnetic clamping structure 120 in the automatic feeding device 100 provided in this embodiment, when it conveys the raw material angle steel 20 in a preset posture. Figure 5The dashed line indicates the position of the raw material angle steel 20 before it is picked up by the magnetic head 121. Figure 6 The dashed line indicates the position of the magnetic clamp structure 120 when the raw material angle steel 20 is placed at the centering clamp 131. Please refer to the reference. Figures 2-6 In this embodiment, a magnetic clamping structure 120 is provided on the front side of the conveying member 111. When feeding, the conveying member 111 drives the raw material angle steel 20 forward along the conveying direction, thereby conveying the raw material angle steel 20 to the magnetic clamping structure 120. The magnetic clamping structure 120 picks up the foremost raw material angle steel 20, while the conveying member 111 drives the remaining raw material angle steel 20 backward, thereby separating the remaining raw material angle steel 20 from the raw material angle steel 20 picked up by the magnetic clamping structure 120.

[0051] The magnetic clamp structure 120 includes a magnetic head 121, which generates magnetic attraction to pick up the raw material angle steel 20. After the magnetic head 121 loses its magnetism, the raw material angle steel 20 detaches from the magnetic head 121. Simultaneously, before detaching, the raw material angle steel 20 is rotated at a certain angle by the magnetic head 121 to adjust to a preset posture. The magnetic head 121 may include, but is not limited to, an electromagnet.

[0052] Optionally, the magnetic suction head 121 includes a first magnetic suction arm 1211 and a second magnetic suction arm 1212 connected to each other and arranged at an included angle. The first magnetic suction arm 1211 is used to magnetically attract one of the first side 21 and the second side 22, and the second magnetic suction arm 1212 is used to magnetically attract the other of the first side 21 and the second side 22, so that the corner of the raw material angle steel 20 is located at the connection position of the first magnetic suction arm 1211 and the second magnetic suction arm 1212. The magnetic suction clamp structure 120 also includes a magnetic suction bracket 122, on which the magnetic suction head 121 is rotatably mounted. The rotation of the magnetic suction head 121 drives the raw material angle steel 20 to flip. Specifically, the magnetic suction clamp structure 120 also includes a telescopic cylinder 128, which is rotatably mounted on the magnetic suction bracket 122 and connected to the magnetic suction head 121. The extension and retraction of the telescopic cylinder 128 drives the magnetic suction head 121 to rotate relative to the magnetic suction clamp.

[0053] Furthermore, the magnetic support 122 includes a magnetic base 123, a clamp base 124, and a sliding part 125. The magnetic base 123 is fixedly installed on the upper end of the clamp base 124, the magnetic head 121 is rotatably installed on the magnetic base 123, the clamp base 124 is vertically mounted on the sliding part 125, and the sliding part 125 is slidably mounted on the frame 110 along the conveying direction, thereby conveying the raw material angle steel 20 to the centering clamp 131.

[0054] Specifically, when the conveyor 111 transports the raw material angle steel 20 to the magnetic clamp, the clamp base 124 drives the magnetic base 123 and the magnetic head 121 to descend to the position corresponding to the corner end 23 of the raw material angle steel 20, and magnetically attracts the first side 21 and the second side 22 through the first magnetic arm 1211 and the second magnetic arm 1212 respectively. Then, the clamp base 124 drives the magnetic base 123 and the magnetic head 121 to rise, so as to lift the raw material angle steel 20 (e.g., Figure 5 As shown), the magnetic head 121 rotates under the drive of the telescopic cylinder 128, thereby causing the raw material angle steel 20 to flip to the position with the corner facing upward (i.e., the preset position). Then the magnetism of the magnetic head 121 disappears, and the raw material angle steel 20 falls onto the frame 110 under its own gravity while maintaining the preset position.

[0055] Furthermore, the magnetic clamp structure 120 also includes a first photoelectric sensor 126 and a second photoelectric sensor 127. The first photoelectric sensor 126 and the second photoelectric sensor 127 are mounted vertically at intervals on the frame 110 and move synchronously relative to the frame 110 with the magnetic clamping bracket 122. The first photoelectric sensor 126 and the second photoelectric sensor 127 are used to detect the position of different height parts of the raw material angle steel 20 to determine the state of the raw material angle steel 20. Thus, the magnetic clamping head 121 can determine the magnetic suction point based on the position of the raw material angle steel 20.

[0056] Specifically, the first photoelectric sensor 126 is fixedly mounted on the fixture base 124, and the second photoelectric sensor 127 is fixedly mounted on the magnetic clamp, with the second photoelectric sensor 127 located at the rotation axis of the magnetic head 121. The precast angle steel automatic production line 10 includes a controller 500. The first photoelectric sensor 126 and the second photoelectric sensor 127 are electrically connected to the controller 500. At the same time, various drive structures in the magnetic clamp structure 120 and various electrical components in the automatic feeding device 100 can be electrically connected to the controller 500 to realize the automated control of the automatic feeding device 100. In use, the first photoelectric sensor 126 and the second photoelectric sensor 127 transmit the detected photoelectric signals to the controller 500. At the same time, the controller 500 controls the clamp base 124 to rise and fall. Then, through the height signals of the first photoelectric sensor 126 and the second photoelectric sensor 127 and the acquired photoelectric signals, the posture of the raw material angle steel 20 to be magnetically attracted is obtained, thereby determining the position of the corner end 23 of the raw material angle steel 20. Then, the magnetic head 121 is controlled to pick up the raw material angle steel 20 and adjust the posture of the raw material angle steel 20 to the preset posture.

[0057] Furthermore, the magnetic base 123 is fixedly installed on the rear side of the upper surface of the clamp base 124. Correspondingly, the front part of the upper surface of the clamp base 124 forms a receiving platform 1241, which is used to support the raw material angle steel 20 in a preset posture and drive the raw material angle steel 20 to the centering clamp 131. Furthermore, the top of the magnetic base 123 also has a pushing slope 1231, which is located on the front side of the magnetic base 123 and is used to push the raw material angle steel 20 in the preset state forward so that the raw material angle steel 20 moves to the receiving position of the receiving platform 1241.

[0058] Specifically, after the magnetic clamping structure 120 magnetically flips the raw material angle steel 20 to a preset posture, the magnetic clamping structure 120 releases the raw material angle steel 20, allowing it to fall. After the raw material angle steel 20 falls, the clamping base 124 moves downward, while the magnetic clamping structure 120 moves backward as a whole. When the magnetic base 123 moves to the rear of the raw material angle steel 20, the clamping base 124 moves upward and, after contacting the raw material angle steel 20 through the pushing inclined surface 1231, pushes the raw material angle steel 20 forward a certain distance. Then, the clamping base 124 moves upward, causing the receiving platform 1241 to lift the raw material angle steel 20 and move it to the centering clamp 131, whereby the raw material angle steel 20 is placed in the centering clamp 131.

[0059] Optionally, the centering clamp 131 includes a first clamping part 132 and a second clamping part 133 arranged opposite to each other, forming a clamping space between the first clamping part 132 and the second clamping part 133. When the magnetic clamping structure 120 places the raw material angle steel 20 in the clamping space, the first clamping part 132 and the second clamping part 133 move synchronously towards each other, thereby clamping the raw material angle steel 20 at the center position between the first clamping part 132 and the second clamping part 133.

[0060] Figure 7 This diagram illustrates the structure of the automatic feeding device 100 provided in this embodiment during length measurement. Please refer to the attached diagram. Figures 2-7 In this embodiment, the dimensions of the first side 21 and the second side 22 of the raw material angle steel 20 are not the same. Specifically, the first side 21 is the long side, and the second side 22 is the short side. Therefore, after the raw material angle steel 20 is flipped to the preset posture, there are two situations: one is that the long side is in front and the short side is behind (e.g., Figure 6As shown in the diagram, another scenario involves the shorter side in front and the longer side behind. To identify the orientation of the raw material angle steel 20, the automatic feeding device 100 also includes an orientation identification component 140. The orientation identification component 140 is located on one side of the centering fixture 131 and is used to detect the raw material angle steel 20 in the centering fixture 131 to identify the position of the first side 21 and the second side 22 in the front-back direction. Specifically, the orientation identification component 140 can detect the front-back direction of the raw material angle steel 20. The orientation identification component 140 is electrically connected to the controller 500, thereby transmitting the identified signal to the controller 500. The controller 500 can then control the front-back direction position during processing based on the front-back position of the raw material angle steel 20 to ensure accurate processing direction without manual intervention.

[0061] It is understandable that in some other embodiments, if the raw material angle steel 20 is an equilateral angle steel, that is, the first side 21 and the second side 22 have the same dimensions, then there is no need to perform direction recognition, and correspondingly, there is no need to set the direction recognition component 140.

[0062] Optionally, the orientation identification element 140 is vertically and flexibly mounted on the frame 110. The orientation identification element 140 identifies the position of the first side 21 or the second side 22 of the centering and clamped raw material angle steel 20 in the front-back direction by contacting them during its downward movement. Specifically, when the raw material angle steel 20 enters the centering clamp 131 and is centered and clamped under the action of the centering clamp 131, the overall position of the raw material angle steel 20 in the front-back direction is fixed. Simultaneously, the orientation identification element 140 is fixed in the front-back direction, and during its descent, it contacts the raw material angle steel 20. Since the raw material angle steel 20 is in a pre-set downward posture, and the slopes of the first side 21 and the second side 22 are different, the height position of the direction recognition component 140 when it contacts the first side 21 and the second side 22 is different. In other words, by the height of the contact position between the direction recognition component 140 and the raw material angle steel 20, it is possible to determine whether the part contacted by the direction recognition component 140 is the first side 21 or the second side 22, thereby realizing the acquisition of the position of the first side 21 and the second side 22 in the front-back direction.

[0063] In this embodiment, the automatic feeding device 100 further includes a length measuring structure 160 and a stop member 162. The automatic feeding device 100 also includes a length direction perpendicular to the conveying direction. The stop member 162 is disposed on one side of the centering clamp 131 along the length direction, and the length measuring structure 160 is slidably disposed along the length direction. The length measuring structure 160 has a measuring part 161, and the measuring part 161 and the stop member 162 are disposed opposite each other on both sides of the centering clamp 131 along the length direction.

[0064] Specifically, after the raw material angle steel 20 is placed in the centering clamp 131, the centering clamp 131 holds and centers the raw material angle steel 20, and then releases it, at which point the raw material angle steel 20 is in the centering position. Then, the length measuring structure 160 moves along the length direction toward the stop member 162, at which point the distance between the measuring part 161 and the stop member 162 shortens. When the measuring part 161 contacts one end of the raw material angle steel 20 in the length direction, it pushes the raw material angle steel 20 toward the stop member 162 until the other end of the raw material angle steel 20 in the length direction contacts the stop member 162. At this point, the distance between the measuring part 161 and the stop member 162 is the length of the raw material angle steel 20. The direction identification member 140 is installed on the measuring part 161. When the measuring part 161 pushes the raw material angle steel 20 to contact the stop member 162, the direction identification member 140 moves downward. Through the contact between the direction identification member 140 and the raw material angle steel 20, direction identification is achieved. After direction recognition is completed, the length measuring structure 160 moves away from the stop 162 to release the raw material angle steel 20. Then the centering clamp 131 clamps and drives the raw material angle steel 20 to continue to be conveyed forward.

[0065] Figure 8 This diagram illustrates the structure of the automatic feeding device 100 provided in this embodiment, in which the feeding arm 130 transports the raw material angle steel 20 to the feeding conveying structure 150. Figure 9 This diagram illustrates the structure of the automatic feeding device 100 provided in this embodiment during material feeding. Please refer to the attached diagram. Figures 2-9 In this embodiment, the automatic feeding device 100 also includes a feeding conveying structure 150, which is located in front of the feeding arm 130 and is used to receive the raw material angle steel 20 sent by the feeding arm 130 and convey it to the cutting and marking device 200 mentioned later.

[0066] Optionally, the feeding and conveying structure 150 includes a floating support 151, a tail chuck 152, and a secondary centering clamping member 153. The floating support 151 supports the raw material angle steel 20, and the secondary centering clamping member 153 is disposed at the floating support 151 to center and position the raw material angle steel 20 supported by the floating support 151. The tail chuck 152 is disposed on one side of the floating support 151 to clamp the tail of the raw material angle steel 20 and push the raw material angle steel 20 to complete the feeding.

[0067] Specifically, the floating support 151 is vertically adjustable, and the tail chuck 152 and the stop 162 are located on the same side of the length direction A. When the feeding arm 130 conveys the raw material angle steel 20 to the floating support 151, the centering clamp 131 releases the raw material angle steel 20, and the floating support 151 rises to a certain height, thereby supporting the raw material angle steel 20 to disengage from the centering clamp 131 on the feeding arm 130. At this time, the feeding arm 130 can retract to wait for the next raw material angle steel 20. At this time, the raw material angle steel 20 located on the floating support 151 is centered and positioned under the action of the secondary centering clamp 153, so that the raw material angle steel 20 is in the clamping position of the tail chuck 152, and then the raw material angle steel 20 is clamped and fixed by the tail chuck 152. Finally, the tail chuck 152 moves along the length direction A towards the cutting and marking device 200, thereby conveying the raw material angle steel 20 to the cutting and marking device 200, thus realizing automatic feeding. Meanwhile, as the tail chuck 152 moves toward the cutting and marking device 200, it will pass the location of the floating support 151. In order to avoid the floating support 151 affecting the movement of the tail chuck 152, the floating support 151 moves downward before the tail chuck 152 moves to its own location, so as to avoid the tail chuck 152.

[0068] like Figure 3 As shown, this embodiment also provides an automatic precast angle steel production line 10. The automatic precast angle steel production line 10 includes the aforementioned automatic feeding device 100, as well as a cutting and marking device 200 and a unloading device 300. The automatic feeding device 100 transports the raw material angle steel 20 to the cutting and marking device 200, where the cutting and marking device 200 processes the raw material angle steel 20 to produce precast angle steel 30 (e.g., ...). Figure 1 (As shown in the two types), the prefabricated angle steel 30 formed by processing is received by the feeding device 300, thereby being fed.

[0069] Figure 10 This diagram illustrates the structure of the precast angle steel automated production line 10 during material cutting, as provided in this embodiment. Please refer to the attached diagram. Figure 3 and Figure 10 In this embodiment, the cutting and marking device 200 is provided with multiple receiving plates 210, which are spaced apart. The precast angle steel 30 formed behind the frame 110 of the cutting and marking device 200 is received by the receiving plates 210. The unloading device 300 includes a conveyor belt 320 and multiple receiving arms 310, which are spaced apart from adjacent receiving plates 210. When receiving material, the receiving arms 310 move to the space between the receiving plates 210 to receive the precast angle steel 30 on the receiving plates 210. Then, the receiving arms 310 retract, driving the precast angle steel 30 to the conveyor belt 320 for subsequent conveying.

[0070] Furthermore, the precast angle steel automated production line 10 also includes a palletizing robot 400 installed at the unloading device 300. The palletizing robot 400 is used to stack the precast angle steel 30 conveyed by the unloading device 300. Specifically, the palletizing robot 400 is located at the tail of the conveyor belt 320, and multiple material frames 410 are provided at the palletizing robot 400. The palletizing robot 400 picks up the precast angle steel 30 conveyed by the conveyor belt 320 and transfers it to the material frames 410 for mechanical stacking. At the same time, the palletizing robot 400 is electrically connected to the controller 500, and under the control of the controller 500, it stacks the precast angle steel 30 into different material frames 410 according to its type. Optionally, a sensor (not shown) can be installed at the tail of the conveyor belt 320. When the sensor detects that precast angle steel 30 has been conveyed to the tail of the conveyor belt 320, the controller 500 controls the palletizing robot 400 to stack the precast angle steel 30.

[0071] The automatic feeding device 100 and the prefabricated angle steel automatic production line 10 provided in the embodiments of the present invention, in use, place the raw material angle steel 20 at the conveyor 111, the conveyor 111 drives the raw material angle steel 20 to the magnetic clamping structure 120, the magnetic head 121 magnetically attracts the raw material angle steel 20 located at the foremost side, then the conveyor 111 drives the raw material angle steel 20 that is not magnetically attracted to retract, the magnetic clamping structure 120 drives the magnetically attracted raw material angle steel 20 to move forward a certain distance, thereby causing the magnetically attracted raw material angle steel 20 to separate from the raw material angle steel 20 that is not magnetically attracted, and then the magnetic head 121 flips to magnetically attract the raw material angle steel 20. The angle steel 20 is adjusted to a preset posture, and the magnetic clamping structure 120 transports the angle steel 20 in this preset posture to the centering clamp 131. The centering clamp 131 clamps the angle steel 20 to position it. Then, the length measuring structure 160 pushes the angle steel 20 to a position where it contacts the stop 162, thus measuring the length of the angle steel 20. After obtaining this length information, the controller 500 can calculate the quantity of angle steel 20 processed and the remaining length of angle steel 20 after processing, ensuring stable subsequent processing. At the same time, the direction recognition component 140 acquires the forward and backward direction of the angle steel 20 in the centering clamp 131. After obtaining this direction information, the controller 500 can control the processing direction of the cutting and marking device 200 during machining to ensure accurate processing. After direction recognition is completed, the length measuring structure 160 moves away from the stop 162, releases the raw material angle steel 20, and then the centering clamp 131 clamps the raw material angle steel 20. The feeding arm 130 extends forward to transport the raw material angle steel 20 to the floating support 151. The secondary centering clamp 153 clamps and centers the raw material angle steel 20 on the floating support 151, and the tail end of the raw material angle steel 20 is clamped by the tail chuck 152 to feed it into the cutting and marking device 200.

[0072] The cutting and marking device 200 processes the raw material angle steel 20 to produce precast angle steel 30. The processed precast angle steel 30 falls onto the receiving plate 210. The receiving arm 310 moves the precast angle steel 30 on the receiving plate 210 to the conveyor belt 320. Under the conveyor belt 320, it moves to the palletizing robot 400. The palletizing robot 400 stacks the precast angle steel 30 conveyed by the unloading device 300 into the material frame 410, thus completing the fully automatic production process of the precast angle steel 30. This process does not require manual intervention, improving the degree of automation and production efficiency.

[0073] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
