DETAILED DESCRIPTION

[0031] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0032] A preferred embodiment of a bulb flat steel processing and conveying device of the present invention is as follows: Figures 1 to 8 As shown, the bulb flat steel processing and conveying device includes a feed roller 2 and a cutting unit 1. The cutting unit 1 is arranged at one end of the feed roller 2. The feed roller 2 is used to convey the bulb flat steel profile to be cut to the cutting unit 1. The cutting unit 1 is used to cut the bulb flat steel profile. The cutting unit 1 can adopt an existing cutting machine. Its specific structure is existing technology and will not be described in detail here.

[0033] The feed roller conveyor 2 comprises a frame 21 and conveyor rollers 22. The conveyor rollers 22 are rotatably mounted on the frame 21. The conveyor rollers 22 are arranged in parallel and spaced apart groups. The conveyor rollers 22 support and convey the bulb flats to be cut. The direction in which the conveyor rollers 22 are arranged in parallel is the conveying direction of the conveyor rollers 22. The frame 21 is a frame structure assembled from profiles. Its specific structure can be designed as needed. The frame 21 forms the support base of the feed roller conveyor 2.

[0034] The feed roller 2 also includes a plurality of supporting wheels 3, which are arranged at intervals along the conveying direction of the conveyor roller 22. When the bulb flat steel is transferred to the feed roller 2, the ball head of the bulb flat steel contacts the supporting wheel 3. Each supporting wheel 3 can position and align the bulb flat steel, thereby limiting the bulb flat steel and ensuring the direction of the cutting unit 1 during cutting.

[0035] like Figure 2 and Figure 3 As shown, the supporting wheel 3 has a first abutting surface 31 and a second abutting surface 32 distributed in sequence along the vertical direction. The distance between the first abutting surface 31 and the conveying roller 22 is greater than the distance between the second abutting surface 32 and the conveying roller 22. The distances between the first abutting surface 31, the second abutting surface 32 and the conveying roller 22 are adapted to bulb flat steels of different sizes, wherein the first abutting surface 31 is used to contact with large-sized bulb flat steels, and the second abutting surface 32 is used to contact with small-sized bulb flat steels, so as to be suitable for positioning and aligning bulb flat steels of different sizes.

[0036] The supporting wheel 3 is vertically movable on the frame 21. During its vertical travel, the supporting wheel 3 has a first state in which the first abutting surface 31 abuts the flat steel bulb, and a second state in which the second abutting surface 32 abuts the flat steel bulb. When the supporting wheel 3 moves to the first state, the upper surface of the conveyor roller 22 is horizontally projected onto the first abutting surface 31, and the flat steel bulb on the conveyor roller 22 contacts the first abutting surface 31. When the supporting wheel 3 moves to the second state, the upper surface of the conveyor roller 22 is horizontally projected onto the second abutting surface 32, and the flat steel bulb on the conveyor roller 22 contacts the second abutting surface 32.

[0037] The feed roller table 2 also includes a lifting drive 4, which is disposed on the frame 21 and is in driving connection with the supporting roller 3. The lifting drive 4 is used to drive the supporting roller 3 to move between a first position and a second position to adjust the height of the supporting roller 3. When the specifications of the bulb flat steel change, the lifting drive 4 adjusts the supporting roller 3 to the first position or the second position according to the specifications of the bulb flat steel to process bulb flat steel profiles of different specifications and sizes.

[0038] The bulb flat steel processing and conveying device is provided with a supporting wheel 3 on the frame 21 of the feed roller 2. The supporting wheel 3 has a first abutting surface 31 and a second abutting surface 32 and can be raised and lowered. Since the distance between the first abutting surface 31 and the conveying roller 22 is greater than the distance between the second abutting surface 32 and the conveying roller 22, when the bulb flat steel profile being processed is large, the lifting drive 4 drives the supporting wheel 3 to move vertically to the first state, so that the first abutting surface 31 contacts the bulb flat steel and limits the bulb flat steel; when the bulb flat steel profile being processed is small, the lifting drive 4 drives the supporting wheel 3 to move vertically to the second state, so that the second abutting surface 32 contacts the bulb flat steel and limits the bulb flat steel. It is suitable for positioning and aligning bulb flat steels of different specifications and sizes, and the range of processable profile sizes is wider, which improves the level of automation and reduces labor costs.

[0039] Preferably, the supporting wheel 3 includes a first cone 33 and a second cone 34 stacked vertically, the diameter of the first cone 33 is smaller than the diameter of the second cone 34, the outer circumferential surface of the first cone 33 forms a first abutting surface 31, and the outer circumferential surface of the second cone 34 forms a second abutting surface 32.

[0040] like Figure 3 As shown, the support wheel 3 is formed by a first circular platform 33 and a second circular platform 34. The first abutment surface 31 and the second abutment surface 32 are both outer circumferential surfaces. The bulb flat steel contacts the support wheel 3 at a point, reducing the contact area and thus reducing resistance. In this embodiment, the first circular platform 33 and the second circular platform 34 are integrally formed, ensuring the strength and service life of the support wheel 3 while also facilitating its processing.

[0041] In other embodiments, the supporting wheel 3 may also be a conical wheel, with the upper portion of the conical surface of the supporting wheel 3 forming the first abutting surface 31 and the lower portion forming the second abutting surface 32 .

[0042] Preferably, the supporting wheel 3 further includes a central shaft 35 , the first circular platform 33 and the second circular platform 34 are both rotatably assembled on the central shaft 35 , and the lifting drive member 4 is in transmission connection with the central shaft 35 .

[0043] The first and second frustums 33 and 34 are rotatably assembled on the central axis 35. The spherical flat steel is always in contact with the first abutment surface 31 and the second abutment surface 32 during the transportation process. At this time, the first and second frustums 33 and 34 can rotate around the central axis 35 to reduce the resistance to the transportation of the spherical flat steel.

[0044] Preferably, the lifting drive member 4 includes a hydraulic cylinder, which is in transmission connection with the central shaft 35 .

[0045] The piston rod of the lifting drive member 4 is connected to the central shaft 35. When the piston rod is extended or retracted, the central shaft 35 can be driven to rise and fall, thereby adjusting the height of the wheel 3. The hydraulic cylinder as the lifting drive member 4 is highly sensitive and can accurately adjust the height of the wheel 3.

[0046] Preferably, the conveying roller 22 includes a roller body 221 and a support wheel 222. The support wheel 222 and the roller body 221 are spaced apart along the axial direction of the conveying roller 22. The support wheel 222 is located at one end of the roller body 221 close to the wheel 3. A avoidance groove 223 for avoiding the clamp is formed between the support wheel 222 and the roller body 221. The width of the avoidance groove 223 is less than or equal to 22 mm.

[0047] like Figure 3 As shown, when the bulb flat steel is on the conveying roller 22, the ball head of the bulb flat steel is supported on the supporting wheel 222 and the bottom end is supported on the roller body 221. The avoidance groove 223 between the roller body 221 and the supporting wheel 222 of the conveying roller 22 is used to avoid the clamp. Since the size of the small-sized bulb flat steel is reduced, the width of the avoidance groove 223 is less than 22 mm, which can prevent the bottom end of the small-sized profile from getting stuck in the groove.

[0048] Preferably, it also includes a marking unit 5, which includes a positioning frame 51 and a pushing mechanism 52. The positioning frame 51 is also provided with a positioning reference platform 512 and a moving wheel 511. The moving wheel 511 is movably assembled on the positioning frame 51 along the axial direction of the conveying roller 22. The moving wheel 511 is used to push the ball flat steel to the positioning reference platform 512 during the movement; the pushing mechanism 52 is located at one end of the positioning frame 51 away from the moving wheel 511, and the pushing mechanism 52 is connected between the positioning frame 51 and the feed roller 2. The pushing mechanism 52 is used to convey the ball flat steel to the conveying roller 22.

[0049] The positioning frame 51 is also provided with a detection device, which is arranged at one end of the positioning frame 51 close to the positioning reference platform 512. The detection device is used to detect the specifications of the bulb flat steel. The detection device is signal-connected to the lifting drive member 4 to transmit an action signal to the lifting drive member 4.

[0050] like Figures 4 to 6 As shown, the marking unit 5 comprises a positioning frame 51 and a pushing mechanism 52. When the bulb-shaped flat steel profile falls onto the positioning frame 51, the moving wheels 511 move to push the bulb-shaped flat steel onto the positioning base 512. The bulb-shaped flat steel contacts the positioning base 512 and is clamped and fixed by the moving wheels 511 and the positioning base 512, preventing the bulb-shaped flat steel from moving. The positioning of the bulb-shaped flat steel also limits its position, ensuring that the marking operation can be performed on the bulb-shaped flat steel. In this embodiment, the marking unit 5 also includes a marking robot and a marking gantry. The marking robot can move on the marking gantry and is used to perform marking operations on the bulb-shaped flat steel.

[0051] The pushing mechanism 52 is arranged at one end of the positioning frame 51 away from the moving wheel 511. After the marking robot completes the coding and marking, the pushing mechanism 52 can move the spherical flat steel profile from the positioning frame 51 to the feed roller 2.

[0052] A detection device (not shown in the figure) is set on the positioning frame 51. The detection device can determine the specifications of the bulb flat steel after detecting the specifications of the bulb flat steel, and transmits an action signal to the lifting drive component 4. The lifting drive component 4 adjusts the supporting wheel 3 to the first state or the second state, adjusts the position of the supporting wheel 3, improves the level of automation, and reduces labor costs.

[0053] Preferably, the detection device includes a laser detector, which is mounted on the positioning frame 51 in a pitch-adjustable manner.

[0054] The detection device is formed by a laser detector. Since the laser detector is pitch-adjustable, the laser detector automatically adjusts the pitch angle after detecting the bulb flat steel profile. When the bulb flat steel profile deviates 50 mm from the ball head, the laser tube beam is made at a 30° angle to the bulb flat steel profile. The size of the bulb flat steel can be obtained based on the occlusion signal of the laser beam.

[0055] In other embodiments, the detection device may also be an industrial camera, which takes photos and transmits them to the controller, and the controller determines the specifications of the bulb flat steel profile based on the photos.

[0056] Preferably, a slide rail 513 is provided on the positioning frame 51, and the moving wheel 511 is slidably assembled on the slide rail 513. A driving cylinder 514 is also rotatably assembled on the positioning frame 51, and the piston rod of the driving cylinder 514 is hinged to the moving wheel 511, and the driving cylinder 514 and the moving wheel 511 form a crank slider mechanism.

[0057] like Figure 6 As shown, the moving wheel 511 of the positioning frame 51 is slidably assembled on the slide rail 513. The slide rail 513 has a guiding effect on the moving wheel 511 to ensure the stability of the moving wheel 511 when moving. A crank slider mechanism is formed between the driving cylinder 514 and the moving wheel 511 to ensure the precise movement of the moving wheel 511.

[0058] Preferably, the positioning frame 51 has a first supporting surface 515, a second supporting surface 516 and an inclined surface 517, the inclined surface 517 is smoothly connected between the first supporting surface 515 and the second supporting surface 516, the height of the first supporting surface 515 is greater than the height of the second supporting surface 516, and the positioning reference platform 512 is arranged at the end of the second supporting surface 516 away from the first supporting surface 515.

[0059] like Figure 6 As shown, the height of the first supporting surface 515 of the positioning frame 51 is greater than the height of the second supporting surface 516 and the positioning reference platform 512 is arranged on the second supporting surface 516. After the spherical flat steel profile is supported on the positioning frame 51, the spherical flat steel has a tendency to move toward the second supporting surface 516 under the action of the inclined surface 517. Under the action of the inclined surface 517, the moving wheel 511 can quickly push the spherical flat steel to the positioning reference platform 512, which is easy to use.

[0060] Preferably, the pushing mechanism 52 includes a pushing motor 521, a pushing chain 522 and a pushing block 523. A plurality of sprockets are rotatably assembled on the positioning frame 51. The pushing chain 522 is arranged in a ring shape on the sprocket. The pushing motor 521 is connected to the sprocket for transmission. The pushing block 523 is fixedly assembled on the pushing chain 522. The pushing chain 522 pushes the pushing block 523 to move the ball flat steel during its rotation stroke.

[0061] like Figure 5 and Figure 6 As shown, the pusher motor 521 of the pusher mechanism 52 drives the pusher block 523 via the pusher chain 522. The pusher block 523, along with the pusher chain 522, pushes the flat steel bar, transporting it from the positioning frame 51 to the feed roller 2. Because the pusher chain 522 is arranged in a ring shape on the sprocket, the pusher motor 521 drives the sprocket forward and reverse to adjust the rotation direction of the pusher chain 522. This changes the movement direction of the pusher block 523 and pushes the flat steel bar in the opposite direction. In this embodiment, there are two pusher blocks 523, symmetrically arranged on either side of the positioning frame 51. These two pusher blocks 523 ensure that the flat steel bar is evenly stressed.

[0062] When the pushing motor 521 rotates forward, the pushing block 523 pushes the ball flat steel to the feed roller 2, and then the supporting wheel 3 of the feed roller 2 moves to the corresponding state. The pushing motor 521 rotates reversely, and the pushing block 523 rotates one circle with the pushing chain 522 and then moves to the other side of the ball flat steel. The ball flat steel can be pushed reversely until it is close to the supporting wheel 3 to position the ball flat steel.

[0063] Preferably, it also includes a loading buffer rack 6 and a conveyor chain row 7. The conveyor chain row 7 is arranged at one end of the loading buffer rack 6 close to the marking unit 5. The conveyor chain row 7 is used to transport the flat steel ball to the positioning rack 51.

[0064] like Figure 7 and Figure 8 As shown, the loading buffer rack 6 can temporarily store the ball flat steel to be cut. The loading buffer rack 6 has a chain conveying mechanism, which can move the ball flat steel to the conveying chain row 7. The conveying chain row 7 can also convey the ball flat steel to the positioning rack 51 to realize the transfer of the ball flat steel.

[0065] Preferably, the conveyor chain row 7 and the positioning frame 51 are arranged alternately in the horizontal direction, and one end of the conveyor chain row 7 is hinged to the loading buffer frame 6. The loading buffer frame 6 is also provided with a swinging drive member 71 for driving the conveyor chain row 7 to swing. When the conveyor chain row 7 swings downward, it is used to transport the flat steel ball to the positioning frame 51.

[0066] like Figure 8As shown, the conveyor chain 7 and the positioning frame 51 are arranged in a staggered manner. When the bulb flat steel is transported and moved onto the conveyor chain 7, the swing drive member 71 drives the conveyor chain 7 to swing downward. Under the action of gravity, the bulb flat steel falls onto the positioning frame 51. After the bulb flat steel is marked with inkjet printing, it is pushed to the feed roller 2 by the pushing mechanism 52. At this time, the conveyor chain 7 returns to its initial position under the action of the swing drive member 71 and can continue to transport the bulb flat steel. In this embodiment, the swing drive member 71 is specifically a hydraulic cylinder. The conveyor chain 7 uses a swinging method to transfer the bulb flat steel to the positioning frame 51, ensuring a smooth transfer process.

[0067] In other embodiments, the conveying chain 7 can also be located on the upper side of the positioning frame 51 and arranged obliquely. After the conveying chain 7 transports the ball flat steel to the upper side of the positioning frame 51, the ball flat steel can fall onto the positioning frame 51 by itself under the action of gravity.

[0068] Preferably, a cutting and discharging unit 8 is further included, and the cutting and discharging unit 8 is arranged on a side of the cutting unit 1 away from the feeding roller 2 .

[0069] The cutting and discharging unit 8 is arranged on the side of the cutting unit 1 away from the feeding roller 2, and is used to carry the cut bulb flat steel. In this embodiment, the structure of the cutting and discharging unit 8 can adopt the structure of the loading buffer rack 6, which will not be described in detail here.

[0070] The working process of the bulb flat steel processing and conveying device of the present invention is as follows: the crane places the bulb flat steel profile to be cut on the loading buffer rack 6; according to the production rhythm, the chain conveying mechanism of the loading buffer rack 6 moves the bulb flat steel to the conveyor chain row 7; the conveyor chain row 7 conveys the bulb flat steel to the marking unit 5; then the conveyor chain row 7 swings downward, and the bulb flat steel is placed on the positioning rack 51; the driving cylinder 514 drives the moving wheel 511 to move on the slide rail 513, and the moving wheel 511 pushes the bulb flat steel to the positioning reference platform 51 2 and fixed, after the laser detector adjusts the angle, the laser beam is arranged at 30° with the profile at a position where the profile deviates 50 mm from the ball head to determine the specifications of the bulb flat steel, and the marking robot performs coding and marking operations on the bulb flat steel; after the coding and marking operations are completed, the pushing mechanism 52 works, and the pushing block 523 pushes the bulb flat steel to the feed roller 2, and then the lifting drive 4 drives the supporting wheel 3 to rise to the required height, and the pushing block 523 pushes the bulb flat steel in the opposite direction until it is close to the supporting wheel 3, and the bulb flat steel is transported to the cutting unit 1 for cutting.

[0071] In summary, an embodiment of the present invention provides a ball flat steel processing and conveying device, wherein a supporting wheel is provided on the frame of the feed roller, the supporting wheel has a first supporting surface and a second supporting surface and the supporting wheel can be raised and lowered. Since the distance between the first supporting surface and the conveying roller is greater than the distance between the second supporting surface and the conveying roller, when the ball flat steel profile being processed is large in specification, the lifting drive component drives the supporting wheel to move vertically to the first state, so that the first supporting surface contacts the ball flat steel, and the ball flat steel is limited; when the ball flat steel profile being processed is small in specification, the lifting drive component drives the supporting wheel to move vertically to the second state, so that the second supporting surface contacts the ball flat steel, and the ball flat steel is limited. It is suitable for positioning and aligning ball flat steels of different specifications and sizes, and the range of processable profile sizes is wider, which improves the level of automation and reduces labor costs.

[0072] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
