Description

Technical Field

[0001] This invention relates to the field of keel quality inspection technology, specifically to an automatic synchronous adjustment and processing system for keels. Background Technology

[0002] When producing keel on an automated production line, the keel is transferred and processed between different equipment sections according to the production process.

[0003] During the keel processing, due to the long length of the keel steel strip, there may be situations where the keel spans two or more equipment sections. For example, the steel strip is cut and punched on a punch press, and then rolled into shape on a keel rolling mill. Because the punch press and the keel rolling mill perform different operations, the processing time varies, and the punch press and the keel rolling mill are prone to speed mismatch. When the same steel strip is transported and processed on punch presses and keel rolling mills with mismatched speeds, it will generate tensile stress on the steel strip, causing the steel strip to deform, and the tooth shape and hole diameter to be inconsistent, affecting the quality of the keel product.

[0004] Therefore, in order to avoid affecting the quality of keel products, it is urgent to solve the problem of mismatch between the operating speed of the punch press and the keel rolling mill. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic synchronous adjustment processing system for keel to solve the technical problem of mismatch between the running speed of the punch press and the keel rolling mill in the existing keel processing process.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0007] An automatic synchronous adjustment processing system for keel, comprising:

[0008] Punch press, used for punching, cutting and drilling holes in keel;

[0009] A keel rolling mill, located downstream of the punch press, is used to process keel shapes;

[0010] The detection mechanism is located between the punch press and the keel rolling mill to detect the conveying status of the keel;

[0011] A guide support mechanism is provided between the punch press and the keel rolling mill. The guide support mechanism is connected to the tail of the detection mechanism and is used to support and transport the keel.

[0012] The control device includes the punch press, the keel rolling mill, the detection mechanism, and the guide support mechanism, which are electrically connected to and controlled by the control device.

[0013] The detection mechanism includes a first detection probe and a second detection probe, and a preset conveying interval is set between the first detection probe and the second detection probe. The control device determines whether the keel exceeds the preset conveying interval based on the detection result of the detection mechanism. When the keel exceeds the preset conveying interval, the control device adjusts the running speed of the punch press and the keel rolling mill to match, and simultaneously adjusts the working of the guide support mechanism to support the keel so as to prevent the keel from contacting the ground.

[0014] As a preferred embodiment of the present invention, when the keel exceeds the preset conveying range, the control device adjusts the running speed of the keel mill according to the direction of the keel offset, so that the keel returns to the preset conveying space for conveying.

[0015] When the keel exceeds the preset conveying range and is located above the preset conveying range, the control device controls the keel mill to decelerate; when the keel exceeds the preset conveying range and is located below the preset conveying range, the control device controls the keel mill to accelerate.

[0016] As a preferred embodiment of the present invention, the height of the plane where the keel is horizontally straight and without tension is set as the reference plane, the upper limit height of the preset conveying interval is set below the reference plane, and the lower limit height of the preset conveying interval is half the vertical height of the reference plane. When the keel as a whole is conveyed within the preset conveying interval, it indicates that the keel is in a normal conveying state.

[0017] In a preferred embodiment of the present invention, the first detection probe and the second detection probe are arranged vertically and their detection ends face each other. The control device determines whether the detection mechanism is faulty based on the detection results of the first detection probe and the second detection probe and the sum and difference relationship between the detection results.

[0018] As a preferred embodiment of the present invention, a bottom frame is provided at the bottom of the second detection probe, and a top frame is provided above the second detection probe. The top frame and the bottom frame are arranged in parallel and connected by multiple limiting columns. The first detection probe and the second detection probe are respectively installed on the top frame and the bottom frame.

[0019] The preset conveying interval is set inside the rectangular space enclosed by the top frame, the bottom frame and the surrounding limiting columns. The first detection probe and the second detection probe are facing each other and are respectively set on the vertical center line of the preset conveying space. The difference between the detection distances of the first detection probe and the second detection probe is used to determine whether the keel exceeds the preset conveying interval.

[0020] In a preferred embodiment of the present invention, the limiting column, the top frame, and the bottom frame are configured as insulators.

[0021] In a preferred embodiment of the present invention, the control device includes an information processing unit, a control unit, a primary alarm, a secondary alarm, and a timer. The control unit, the first detection probe, and the second detection probe are electrically connected to the information processing unit, and the punch press, the keel rolling mill, the primary alarm, the secondary alarm, and the timer are electrically connected to the control unit.

[0022] The control unit determines the keel conveying status based on the processing result of the information processing unit. When the control unit determines that the keel is out of normal conveying status, the control unit adjusts the speed of the keel rolling mill and the punch press to match, and the control unit controls the activation of the first-level alarm and starts the timer to count the alarm time of the first-level alarm. If the alarm time counted by the timer reaches the preset duration and the keel still has not returned to the preset conveying range, it indicates that the system equipment is faulty.

[0023] If the detection mechanism detects that the keel is still outside the preset conveying range when the control unit adjusts the speed of the downstream processing equipment to match the speed of the upstream processing equipment, the control unit will control the guiding and supporting mechanism to guide and support the keel to prevent the keel from falling to the ground.

[0024] As a preferred embodiment of the present invention, the guiding and supporting mechanism includes a guide roller group and a squeezing roller group, the guide roller group being disposed upstream of the squeezing roller group, and the guide roller group and the squeezing roller group being respectively mounted by a U-shaped bracket;

[0025] The guide roller assembly is capable of moving vertically. When the keel is conveyed within the preset conveying range, the guide roller assembly provides zero guidance angle to the keel. When the keel exceeds the preset conveying range, the guide roller assembly moves upward and / or downward to increase or decrease the guidance angle to the keel. The guide roller assembly provides vertical guidance and support to the keel at least once, and the extrusion roller assembly extrudes and pulls out the guided keel.

[0026] As a preferred embodiment of the present invention, the guide roller group includes a first guide roller and a second guide roller, and self-adjusting sliding tracks are respectively installed on both sides of the U-shaped bracket corresponding to the first guide roller and the second guide roller. The two ends of the first guide roller and the second guide roller are respectively installed on the self-adjusting sliding tracks through movable connecting blocks, and drive motors are respectively installed at the ends of the first guide roller and the second guide roller.

[0027] The first guide roller and the second guide roller rotate under the drive of the drive motor to guide the keel. The first guide roller and the second guide roller move under the drive of the matched self-adjusting sliding track. The self-adjusting sliding track is connected to the control device and is controlled by the control device.

[0028] As a preferred embodiment of the present invention, the first guide roller is disposed at the bottom of the keel, and the second guide roller is disposed at the top of the keel. Under normal conditions, the keel passes horizontally through the guide roller group. The second guide roller and the first guide roller are tangent to the upper and lower surfaces of the keel, respectively, and the chamfer is zero.

[0029] During the process of the control device regulating the matching of the operating speed of the upstream and downstream processing equipment, the first guide roller moves upward to guide the keel, and the second guide roller moves downward to guide the keel. The vertical movement range of the first guide roller and the second guide roller is not constrained by the preset conveying interval height range of the keel.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] This invention uses a detection mechanism to monitor the keel conveying status. Based on the detection results, problems are identified in a timely manner, and the speed of the processing equipment in the preceding and following sections is automatically adjusted to synchronize and match, so that the keel can be restored to normal conveying status. Furthermore, the guide and support mechanism can support the keel during the speed matching process to prevent it from falling to the ground and ensure the quality of the keel.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] When products are manufactured on an automated production line, they are transported and processed between different sections. Mismatched operating speeds of the processing equipment in these different sections can affect product quality. The following explanation uses the production of light steel frame ribs as an example.

[0046] The steel strip for the keel is conveyed and processed between machines. After steps such as cutting, punching, and bending, it is processed into the keel. Typically, a single steel strip is conveyed and processed simultaneously on multiple machines. However, when the processing speed of the same steel strip on multiple machines does not match the conveying speed of the steel strip, quality problems can easily occur. For example, if the speeds of the punch press and the keel forming machine are mismatched, it will cause the steel strip to be pulled, resulting in inconsistent tooth sizes in the keel punching, affecting the quality of the keel. Therefore, it is necessary to monitor the keel conveying status and adjust the speeds of the upstream and downstream processing equipment to synchronize them.

[0047] like Figure 3 Combination Figure 4As shown, the present invention provides an automatic synchronous adjustment processing system for keel, including a punch press 5, a keel rolling mill 6, a detection mechanism 1, a guide support mechanism 2, and a control device 3. The detection mechanism 1 and the guide support mechanism 2 are arranged between the punch press 5 and the keel rolling mill 6, and the guide support mechanism 2 is connected to the tail of the detection mechanism 1. The detection mechanism 1 is used to detect the conveying status of the keel, and the guide support mechanism 2 supports the conveyed keel.

[0048] The punch press 5, the keel rolling mill 6, the detection mechanism 1, and the guide support mechanism 2 are electrically connected to the control device 3 and are controlled by the control device 3.

[0049] The punch press 5 cuts and punches holes in the steel strip to obtain hooks and mounting holes. The cut and punched steel strip is then pulled out through the downstream keel mill 6. There is a space between the punch press 5 and the keel mill 6. During normal conveying, the steel strip is conveyed in a suspended state between the keel mill 6 and the punch press 5.

[0050] The operating speed of the keel rolling mill 6 and the punch press 5 is related to the conveying state of the keel steel strip, that is, the sag of the keel steel strip when it is suspended: the steel strip is taut and straight (small sag) or hanging and stacked (large sag).

[0051] The 6 pairs of keel (steel strip) of the keel rolling mill have a relatively high pulling speed, so the steel strip is taut and straight with little sag. The 6 pairs of steel strip of the keel rolling mill have a relatively low pulling speed, so the steel strip is loose and hangs down. The ideal conveying state of the steel strip is that the steel strip has no tension, has a certain sag, is conveyed in the air, but will not fall to the ground and pile up.

[0052] A preset conveying interval is set in the testing mechanism 1, and the steel belt passes through the preset conveying interval to detect the sag of the keel steel belt.

[0053] The control device 3 adjusts the speed of the punch press 5 to maintain a stable processing speed. In other words, if a speed mismatch occurs, the speed of the downstream keel rolling mill 6 can be adjusted without changing the processing speed of the punch press 5, so as to ensure the processing quality of the keel.

[0054] When the keel exceeds the preset conveying range, the control device 3 adjusts the running speed of the keel mill 6 according to the direction of the keel offset, so that the keel returns to the preset conveying space: when the detection mechanism 1 detects that the keel sag is lower than the lower limit height of the preset conveying range, the control device 3 controls the keel mill 6 to decelerate; when the detection mechanism 1 detects that the keel sag is greater than the preset state, the control device 3 controls the keel mill 6 to accelerate.

[0055] Specifically, the detection mechanism 1 includes a first detection probe 11 and a second detection probe 12. A preset conveying interval is set between the first detection probe 11 and the second detection probe 12. The control device 3 determines whether the keel exceeds the preset conveying interval based on the detection result of the detection mechanism 1. When the keel exceeds the preset conveying interval, the control device 3 adjusts the running speed of the keel rolling mill 6 and the punch press, and simultaneously adjusts the working of the guide support mechanism 2 to support the keel and thus prevent the keel from contacting the ground.

[0056] The control device 3 adjusts the speed matching between the keel rolling mill 6 and the punch press 5. It does not necessarily mean that the keel rolling mill 6 and the punch press 5 run at the same speed. It is enough to keep the keel steel strip conveyed within the preset conveying range. The running speed of the keel rolling mill 6 is dynamically adjusted so that the keel steel strip maintains a certain sag and is conveyed as a whole within the preset conveying range.

[0057] The first detection probe 11 and the second detection probe 12 are arranged vertically with their detection ends facing each other. The control device 3 determines whether the detection mechanism 1 is faulty based on the detection results of the first detection probe 11 and the second detection probe 12 and the sum and difference relationship between the detection results.

[0058] The first detection probe 11 and the second detection probe 12 are installed in fixed positions, and the distance between the first detection probe 11 and the second detection probe 12 is a fixed value. Therefore, the sum of the detection distances of the first detection probe 11 and the second detection probe 12 is a fixed value. If the sum of the detection distances of the first detection probe 11 and the second detection probe 12 changes, it indicates that there is a problem with the detection of the first detection probe 11 or the second detection probe 12, and maintenance and repair are required.

[0059] like Figure 1 The diagram shows a three-dimensional structural schematic of the detection mechanism 1. A bottom frame 14 is provided at the bottom of the second detection probe 12, and a top frame 13 is provided above the second detection probe 12. The top frame 13 and the bottom frame 14 are arranged in parallel and connected by multiple limiting columns 15. The limiting columns 15, the top frame 13 and the bottom frame 14 are set as insulators to avoid interfering with the operation of the first detection probe 11 and the second detection probe 12. The first detection probe 11 and the second detection probe 12 are respectively installed on the top frame 13 and the bottom frame 14.

[0060] The preset conveying interval is set inside the rectangular space enclosed by the top frame 13, the bottom frame 14, and the surrounding limiting columns 15. The first detection probe 11 and the second detection probe 12 are facing each other and are respectively set on the vertical center line of the preset conveying space. Based on the difference in the detection distance of the first detection probe 11 and the second detection probe 12, it is determined whether the keel exceeds the preset conveying interval, realizing the automated detection of the keel conveying status. Compared with manual detection, it can be applied to the entire production line and is more efficient.

[0061] Before the keel rolling mill 6 is adjusted to match the speed of the punch press 5, the speed of the keel rolling mill 6 is in a state of dynamic change, while the punch press 5 remains in processing state, and the keel steel strip may exceed the preset conveying range. In this embodiment, by setting the guide roller group 21, when the keel steel strip has a large sag, a section of the keel steel strip between the equipment is lifted upward as a whole, to prevent the keel steel strip from contacting the ground.

[0062] The guide support mechanism 2 includes a guide roller group 21 and a squeeze roller group 23. The guide roller group 21 is located upstream of the squeeze roller group 23, and the guide roller group 21 and the squeeze roller group 23 are respectively installed by a U-shaped bracket 22.

[0063] The guide roller group 21 is capable of moving in the vertical direction. When the keel is conveyed within the preset conveying range, the guide roller group 21 guides the keel at a zero angle. When the keel exceeds the preset conveying range, the guide roller group 21 moves upward and / or downward to increase or decrease the guide angle on the keel. The guide roller group 21 guides and supports the keel in the vertical direction at least once. The extrusion roller group 23 extrudes and pulls out the guided keel.

[0064] At least two guide rollers are installed to traction and support the keel steel strip, reducing the sag of the steel strip and preventing it from falling to the ground.

[0065] This embodiment uses the setting of two guide rollers as an example for detailed explanation, as follows:

[0066] like Figure 2 As shown, the guide roller assembly 21 includes a first guide roller 211 and a second guide roller 212. Self-adjusting sliding tracks 213 are respectively installed on both sides of the U-shaped bracket 22 corresponding to the first guide roller 211 and the second guide roller 212. The two ends of the first guide roller 211 and the second guide roller 212 are respectively installed on the self-adjusting sliding tracks 213 through movable connecting blocks 215. A drive motor 214 is respectively installed at the ends of the first guide roller 211 and the second guide roller 212.

[0067] The first guide roller 211 and the second guide roller 212 rotate under the drive of the drive motor 214 to guide the keel. The first guide roller 211 and the second guide roller 212 move under the drive of the matched self-adjusting sliding track 213. The self-adjusting sliding track 213 is connected to the control device 3 and is controlled by the control device 3.

[0068] The self-adjusting sliding track 213 includes a sliding track, a screw, and a drive motor. The screw passes through a movable connecting block 215. The drive motor drives the screw to rotate, and the movable connecting block 215 moves along the screw under its influence. The two ends of the first guide roller 211 (and the second guide roller 212) are respectively fixedly installed on the movable connecting block 215. The installation positions of the first guide roller 211 and the screw on the movable connecting block 215 do not overlap. Figure 2As can be seen, the screw is installed through the center of the movable connecting block 215, and the first guide roller 211 or the second guide roller 212 is eccentrically connected to the movable connecting block 215. The rotation of the screw and the rotation of the first guide roller 211 do not affect each other.

[0069] Since the purpose of setting the guide rollers is to support the keel steel strip, the first guide roller 211 is set at the bottom of the keel and the second guide roller 212 is set at the top of the keel.

[0070] Under normal conditions, the keel passes horizontally through the guide roller group 21. The second guide roller 212 and the first guide roller 211 are tangent to the upper and lower surfaces of the keel, respectively, and the chamfer is zero. Figure 3 As shown in the image.

[0071] When the speeds of the upstream and downstream processing equipment are not synchronized, resulting in a large sag of the steel strip, the first guide roller 211 moves upward to guide the keel, and the second guide roller 212 moves downward to guide the keel. The vertical movement range of the first guide roller 211 and the second guide roller 212 is not constrained by the preset conveying interval height range of the keel.

[0072] In addition, the steel strip section of the keel leading from the preset conveying section of the detection mechanism 1 to the first guide roller 211 does not contact the top frame 13 and the limiting column 15 of the detection mechanism 1, so as to avoid the steel strip from rubbing against the frame of the detection mechanism 1 and causing scratches or creases.

[0073] Based on the aforementioned keel automatic synchronous adjustment processing system, this application further provides the adjustment method and process of the synchronous adjustment processing system, such as... Figure 7 The flowchart shows the steps:

[0074] The system starts up and performs a self-check for faults.

[0075] The system's power-on self-test includes, but is not limited to, checking whether the operating voltage and current of each operating module of the control device are operating normally, and whether the two detection probes of the detection mechanism 1 can perform mutual testing and detect normally.

[0076] The control device 3 determines whether the keel is in normal transport state based on the detection results of the detection mechanism 1.

[0077] The keel sag within the preset conveying range indicates that the keel is in normal conveying state. The plane height where the keel is horizontally straight and without tension is set as the reference plane. The upper limit height of the preset conveying range is set below the reference plane, and the lower limit height of the preset conveying range is half the vertical height of the reference plane.

[0078] When the keel exceeds the normal conveying state, the control device 3 adjusts the running speed of the punch press 5 and the keel rolling mill 6 to match; during the speed matching adjustment process, when the control device 3 determines that the keel steel strip exceeds the lower limit height of the preset conveying range based on the real-time monitoring results of the detection mechanism 1, it controls the guide support mechanism 2 to work to avoid the keel contacting the bottom surface during the speed matching adjustment process; after the keel returns to the normal conveying state, the control device regulates the guide support mechanism to reset.

[0079] For example, assuming the keel steel strip is taut and straightened, and its height is flush with the height during processing on the punch press 5, using this as a horizontal reference line, the first detection probe 11 is fixedly set 20 cm above the horizontal reference line, and the second detection probe 12 is fixedly set 80 cm below the horizontal reference line. Figure 5 As shown in the image.

[0080] The detection distance range of the first detection probe 11 is set to 30-60 cm, and the detection distance range of the second detection probe 12 is set to 70-40 cm. The difference between the second detection probe 12 and the first detection probe 11 varies between 40 and -20 cm. The upper limit of sag during the conveying process of the steel belt is 10 cm below the horizontal baseline, and the lower limit of sag during the conveying process of the steel belt is 40 cm below the horizontal baseline. The steel belt is kept hanging within a 30 cm range between the upper limit and the lower limit of sag.

[0081] The steel strip is relatively thin. Compared with the total length of 100 cm, the thickness of the steel strip accounts for a very small distance. For the sake of calculation and description, the thickness of the steel strip is negligible. Thus, the sum of the detection distances of the first detection probe 11 and the second detection probe 12 is fixed at 100 cm.

[0082] When the keel conveying state is set in the control device 3 such that the difference between the detection value of the second detection probe 12 and the first detection probe 11 is greater than 40 cm, the control device 3 controls the keel rolling mill 6 to decelerate; when the keel conveying state is set in the control device 3 such that the difference between the second detection probe 12 and the first detection probe 11 is less than -20 cm, the control device 3 controls the keel rolling mill 6 to accelerate.

[0083] The control device 3 controls the guide support mechanism 2 to support the keel steel belt, so as to keep the keel steel belt within the preset conveying range. After reaching the preset conveying range, the control device 3 will no longer adjust the first guide roller 211 and the second guide roller 212 to continue to move up and down, so as to avoid excessive adjustment and the opposite effect.

[0084] The control device 3 includes an information processing unit 32, a control unit 31, a primary alarm 33, a secondary alarm 34, and a timer 35. The control unit 31, the first detection probe 11, and the second detection probe 12 are electrically connected to the information processing unit 32, respectively. The punch press 5, the keel rolling mill 6, the primary alarm 33, the secondary alarm 34, and the timer 35 are electrically connected to the control unit 31, respectively.

[0085] like Figure 6 The control signal flow diagram of the control device 3 is given. The control unit 31 judges the keel conveying status according to the processing result of the information processing unit 32. When the control unit 31 determines that the keel exceeds the normal conveying status, the control unit 31 adjusts the speed of the keel rolling mill 6 and the punch press 5 to match. The control unit 31 controls the activation of the first-level alarm 33 to sound an alarm. At the same time, the timer 35 is activated to count the alarm time of the first-level alarm 33. If the counted alarm time reaches the preset duration but the keel still has not returned to the preset conveying range, it indicates that the system equipment is faulty. Then the control device 3 controls the second-level alarm 34 to start the alarm.

[0086] During the process of adjusting the speed of the keel rolling mill 6 and the speed of the punch press 5 by the control unit 31, if the detection mechanism 1 detects that the keel is still outside the preset conveying range, the control unit 31 controls the guide support mechanism 2 to guide the keel to avoid the keel falling to the ground.
