Description

Technical Field

[0001] This invention relates to the field of profile cutting, and in particular to an automatic profile loading and unloading control method, device and automatic profile cutting system. Background Technology

[0002] Currently, the steel structure industry, petrochemical industry and marine engineering industry have a very large demand for profile cutting. The operating cycle of conventional profile cutting machines is difficult to meet their workload requirements and the frequent material changes and the large amount of time wasted in the material change process have also hindered the development of the cutting automation process in the above-mentioned industries. At present, most companies in the industry still use manual cutting of profiles.

[0003] Existing automated profile cutting machines require hundreds of square meters of floor space, resulting in extremely high equipment costs. The exorbitant purchase price of the equipment, along with the substantial annual workshop rental costs, significantly hinders the widespread adoption of this technology. The harsh working conditions in these industries lead to high worker turnover and management difficulties, creating a strong desire for automated cutting. However, the high cost of existing cutting equipment compared to manual material handling prevents its widespread adoption.

[0004] Therefore, there is an urgent need for a low-cost, low-footprint, and highly efficient automatic profile loading and unloading control method, device, and profile cutting system. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic profile loading and unloading control method, device, and automatic profile cutting system. The automatic profile loading and unloading control method of this invention adopts a completely different loading method from existing technologies. The entire process of loading and unloading is completed in the unloading roller conveyor area of ​​existing technologies. This automatic loading and unloading method in the same area greatly simplifies the mechanical structure, reduces equipment manufacturing costs, and enables simultaneous loading and unloading during the cutting process, thereby improving production efficiency.

[0006] This invention provides an automatic profile loading and unloading control method, including an automatic loading and unloading mechanism. The automatic loading and unloading mechanism comprises a base, a roller conveyor support, at least two roller conveyor stations, and a transverse drive mechanism. The roller conveyor support is mounted on the base and moves laterally back and forth on the base under the drive of the transverse drive mechanism, thereby aligning each roller conveyor station with the discharge port of the cutting mechanism. A moving feeding trolley clamps a first profile located at the first roller conveyor station and drags the first profile along the feeding roller conveyor until the first profile is completely dragged onto the feeding roller conveyor. After the first profile is cut... After completion, the moving feeding trolley places the first workpiece formed by the cutting of the first profile and the remaining first profile scrap completely on the first roller conveyor station; the moving roller conveyor support aligns the second roller conveyor station with the discharge port of the cutting mechanism, while the first roller conveyor station moves away from the discharge port of the cutting mechanism; the moving feeding trolley clamps the second profile on the second roller conveyor station and drags the second profile along the feeding roller conveyor until the second profile is completely dragged onto the feeding roller conveyor; during the cutting of the second profile, the first workpiece and the remaining first profile scrap on the first roller conveyor station on the roller conveyor support are cleaned.

[0007] Furthermore, before performing the feeding operation, it also includes determining whether there is a profile to be cut on the feeding roller conveyor. If there is, the profile cutting operation is performed. If not, it is determined whether there is a profile to be cut on the first roller conveyor station. If not, the first profile is placed on the first roller conveyor station.

[0008] Furthermore, before performing the feeding operation, it is determined whether the first roller conveyor station is aligned with the cutting mechanism's outlet. If not, the roller conveyor support is moved so that the first roller conveyor station is aligned with the cutting mechanism's outlet.

[0009] Furthermore, during the first profile cutting process, it is determined whether there is a profile to be cut on the second roller conveyor station. If not, the second profile is placed on the second roller conveyor station.

[0010] Furthermore, the "moving roller support to align the second roller station with the cutting mechanism outlet and the first roller station away from the cutting mechanism outlet" includes: a servo motor controlling the feeding trolley to move backward along the longitudinal track, causing the extended gripper of the feeding trolley to exit the cutting mechanism outlet; a transverse drive mechanism driving the roller support to move along the transverse track; and adjusting the position of the roller support on the base by an adjustable limit mechanism set on the transverse track, so that the second roller station is aligned with the cutting mechanism outlet.

[0011] Furthermore, the description of "moving the feeding trolley to clamp the first profile located at the first roller conveyor station and dragging the first profile along the feeding roller conveyor until the first profile is completely dragged onto the feeding roller conveyor" includes: a servo motor controlling the feeding trolley to approach the cutting mechanism along the longitudinal track; the extended grippers of the feeding trolley extending out of the discharge port of the cutting mechanism and clamping the first profile at the first roller conveyor station under the control of a pneumatic or hydraulic drive mechanism; and the servo motor controlling the feeding trolley to drag the first profile backward along the longitudinal track until the first profile is completely dragged onto the feeding roller conveyor.

[0012] This invention also provides an automatic profile loading and unloading device, including an automatic loading and unloading mechanism and a feeding roller conveyor mechanism. The automatic loading and unloading mechanism includes a base, a roller conveyor support, at least two roller conveyor stations, and a transverse drive mechanism. The roller conveyor support is mounted on the base and moves laterally back and forth on the base under the drive of the transverse drive mechanism, so that each roller conveyor station is aligned with the discharge port of the cutting mechanism. The feeding roller conveyor mechanism includes a feeding roller conveyor, a feeding trolley, and a servo motor. Longitudinal tracks are installed on both sides of the feeding roller conveyor, and matching traveling racks are set on the longitudinal tracks. Correspondingly, the feeding trolley is equipped with gears and is mounted on the longitudinal tracks of the feeding roller conveyor via gears. Servo motors are installed on both sides of the feeding trolley, and the servo motors drive the gears to move back and forth on the traveling racks. The feeding trolley is also equipped with a pair of pneumatically or hydraulically controlled extended grippers. The automatic profile loading and unloading device is used to execute the aforementioned automatic profile loading and unloading control method.

[0013] Furthermore, the extended grippers have replaceable toothed plates to prevent the profile from slipping during dragging and cutting.

[0014] Furthermore, the roller conveyor station includes multiple rollers spaced apart along the centerline of the roller conveyor support, with a tray placed between adjacent rollers.

[0015] The present invention also provides an automatic profile cutting system, including the aforementioned automatic profile loading and unloading device and a cutting mechanism. The automatic loading and unloading mechanism is set at the discharge port of the cutting mechanism to realize the loading and unloading operations during the cutting process. The feeding roller is set at the loading port of the cutting mechanism to realize the operation of conveying the profile during the cutting process. The cutting mechanism is used to realize the cutting operation of the profile.

[0016] The beneficial effects of this invention are as follows:

[0017] This invention employs a completely different feeding method from existing technologies. The entire process of feeding and unloading is completed within the original unloading roller conveyor area, achieving automatic feeding and unloading in the same location. This greatly simplifies the mechanical structure and reduces equipment manufacturing costs. The feeding roller conveyor of the cutting machine is only used as a cutting feed roller conveyor and is no longer used as a feeding area. Furthermore, because feeding and unloading operations can be completed during the cutting process, the efficiency of profile cutting is improved.

[0018] Furthermore, because loading and unloading occur in the same area, it avoids the need for handling equipment such as overhead cranes or forklifts to travel back and forth between the original loading and unloading areas. According to the technical solution of this invention, the handling equipment only needs to operate within the existing automated loading and unloading area, reducing handling time and equipment costs.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Figure 1 A flowchart of an automatic profile loading and unloading control method according to the present invention is shown. This method can be applied to automatic loading and unloading in the profile cutting process. For ease of description, the present invention defines the station used for the first loading in one loading and unloading cycle of the automatic profile loading and unloading device as the first roller conveyor station and the other station as the second roller conveyor station. The "first roller conveyor station" and the "second roller conveyor station" are used alternately as the loading station and the unloading station. This is only used to describe the loading and unloading process in one loading and unloading cycle of the automatic profile loading and unloading device of the present invention, and is not used to limit the order of use of the stations of the automatic profile loading and unloading device. That is, when the automatic profile loading and unloading device is used, loading can also start from the second roller conveyor station.

[0033] Specifically, the automatic profile loading and unloading control method of the present invention includes the following steps:

[0034] S100, the moving feeding trolley 202 clamps the first profile located at the first roller conveyor station 103 and drags the first profile along the feeding roller conveyor until the first profile is completely dragged onto the feeding roller conveyor 201.

[0035] Preferably, step S100 further includes determining whether there is a profile to be cut on the first roller conveyor station 103; if not, placing the first profile on the first roller conveyor station 103.

[0036] At the beginning of the automatic profile loading and unloading method of the present invention, it is first determined whether there is a profile to be cut on the feeding roller conveyor. If there is, the profile cutting operation is performed. If not, it is determined whether there is a profile to be cut on the first roller conveyor station 103. If there is no profile to be cut on the first roller conveyor station 103, the handling equipment is controlled to place the first profile on the first roller conveyor station 103. If there is a profile to be cut on the first roller conveyor station 103, step S100 is directly executed. If there is a workpiece that has been cut and profile residue on the first roller conveyor station 103, the workpiece and profile residue are cleaned up and step S100 is executed.

[0037] Preferably, step S100 further includes determining whether the first roller conveyor station 103 is aligned with the material outlet of the cutting mechanism; if not, moving the roller conveyor support so that the first roller conveyor station 103 is aligned with the material outlet of the cutting mechanism.

[0038] After aligning the first roller conveyor station 103 with the material outlet of the cutting mechanism, the automatic loading and unloading control method for profiles provided by this invention can be applied to perform automatic loading and unloading operations on the first profile on the first roller conveyor station 103.

[0039] For example, in one application example of the automatic profile loading and unloading control method, such as Figure 2 As shown, the present invention also provides an automatic profile loading and unloading device, which can apply the automatic profile loading and unloading control method of the present invention. The device includes an automatic loading and unloading mechanism 100 and a feeding roller conveyor mechanism 200. The automatic loading and unloading mechanism is located at the discharge port of the cutting mechanism to realize the loading and unloading operations during the cutting process. The feeding roller conveyor mechanism is located at the loading port of the cutting mechanism to realize the conveying operation of the profile during the cutting process. Specifically, in conjunction with… Figure 3 , Figure 4 The automatic loading and unloading mechanism includes a base 101, a roller support 102, a first roller station 103, a second roller station 104, and a transverse drive mechanism 105. The roller support 102 is mounted on the base 101 and can move back and forth transversely on the base 101 under the drive of the transverse drive mechanism 105, so that the first roller station 103 and the second roller station 104 are respectively aligned with the discharge port of the cutting mechanism, which facilitates the loading, unloading and cutting of profiles.

[0040] Furthermore, such as Figure 4 As shown, the lateral drive mechanism 105 is a cylinder.

[0041] The first roller conveyor station 103 and the second roller conveyor station 104 are arranged in parallel on the roller conveyor support 102 and do not interfere with each other. Each roller conveyor station includes multiple rollers spaced apart along the centerline of the roller conveyor support. By setting the rollers, the profile can move along the centerline of the roller conveyor and reduce friction, realizing loading and unloading. Preferably, the first roller conveyor station 103 and the second roller conveyor station 104 are used alternately as loading and unloading stations. By moving the roller conveyor support laterally, one of the stations is aligned with the discharge port of the cutting mechanism for loading or unloading.

[0042] In the automatic profile loading and unloading control method of the present invention, a first profile is placed on the first roller conveyor station 103 and the first roller conveyor station 103 is aligned with the material outlet of the cutting mechanism.

[0043] Furthermore, the base 101 is provided with multiple sets of transverse tracks, and the roller conveyor support is disposed on the transverse roller conveyor. The transverse tracks are used to guide the roller conveyor support. Furthermore, the automatic loading and unloading mechanism of the present invention also includes an adjustable limiting mechanism 106, such as... Figure 5 As shown, an adjustable limiting mechanism is mounted on the transverse track to adjust the position of the roller conveyor support on the base 101 so that one of the roller conveyor stations is aligned with the material outlet of the cutting mechanism for loading or unloading. Furthermore, the adjustable limiting mechanism 106 can be a mechanical stop.

[0044] Specifically, in application examples of the present invention, such as Figure 6-7 As shown, the feeding roller conveyor mechanism 200 includes a feeding roller conveyor 201. Longitudinal rails are installed on both sides of the feeding roller conveyor 201 in a direction parallel to its centerline. A feeding trolley 202 is mounted on the longitudinal rails. Furthermore, a matching traveling rack is provided on the longitudinal rails, and correspondingly, a gear is provided on the feeding trolley 202. Servo motors 203 are provided on both sides of the feeding trolley 202. The servo motors 203 can drive the gears to reciprocate on the traveling rack, thereby enabling the feeding trolley 202 to reciprocate along the feeding roller conveyor.

[0045] Furthermore, the feeding trolley 202 is equipped with a pair of pneumatically or hydraulically controlled extended grippers 2021. The pneumatic or hydraulic control device is mounted on the feeding trolley 202. The extended grippers 2021 allow the feeding trolley 202 to extend from the feeding roller conveyor beyond the discharge port of the cutting mechanism and clamp the first profile on the first roller conveyor station 103. During loading, if... Figure 8As shown, driven by the servo motor 203, the feeding trolley 202 moves forward along the longitudinal track to approach the cutting structure. The extended gripper 2021 extends out of the discharge port of the cutting mechanism and clamps the first profile on the first roller conveyor station 103 under the control of the pneumatic or hydraulic drive mechanism. Subsequently, driven by the servo motor 203, the first profile is dragged backward along the longitudinal track until it is completely dragged onto the feeding roller conveyor, completing the feeding operation. In the above feeding process, preferably, the roller on the first roller conveyor station 103 can reduce the friction of the first profile during dragging by rotating.

[0046] S200, after the first profile is cut, the moving feeding trolley 202 places the first workpiece formed by the first profile cutting and the remaining first profile scrap completely on the first roller conveyor station 103.

[0047] Furthermore, during the cutting process of the first profile, it is determined whether there is a profile to be cut on the second roller conveyor station 104. If not, the second profile is placed on the second roller conveyor station 104. This allows the cutting of the second profile to be performed as soon as possible after the first profile is cut, thereby improving work efficiency.

[0048] Furthermore, during the cutting of the first profile, the feeding trolley 202 pushes the first profile along the feeding roller conveyor until the first profile is cut. After the first profile completes the last cut, the servo motor 203 continues to control the feeding trolley 202 to push the material forward until the remaining material of the first profile is also completely placed on the first roller conveyor station 103.

[0049] Furthermore, the extended gripper 2021 is equipped with replaceable toothed plates to increase friction and prevent the profile from slipping during dragging and cutting.

[0050] Furthermore, a tray 107 is provided between adjacent rollers on adjacent roller conveyor stations to prevent the first workpiece or the first profile scrap after cutting from falling from the middle of the rollers because it is shorter than the distance between adjacent rollers.

[0051] S300, move the roller support so that the second roller station 104 is aligned with the outlet of the cutting mechanism, and the first roller station 103 leaves the outlet of the cutting mechanism.

[0052] Specifically, after the first profile is cut, the servo motor 203 controls the feeding trolley 202 to move backward along the longitudinal track, causing the extended gripper 2021 of the feeding trolley 202 to exit the cutting mechanism's outlet, thus avoiding the second profile on the first roller conveyor station 103 and the second roller conveyor station 104. The cylinder pushes the mechanism along... Figure 9Move the roller support in the direction of the arrow shown, so that the first roller station 103 is away from the outlet of the cutting mechanism, and the second roller station 104 is aligned with the outlet of the cutting mechanism, ready to perform feeding and cutting operations on the second profile.

[0053] S400, the moving feeding trolley 202 clamps the second profile on the second roller conveyor station 104 and drags the second profile along the feeding roller conveyor until the second profile is completely dragged onto the feeding roller conveyor.

[0054] Similar to the feeding process of the first profile, refer to Figure 9 The servo motor 203 controls the feeding trolley 202 to move along the feeding roller conveyor, pass through the discharge port of the cutting mechanism, and cause the extended gripper 2021 to clamp the second profile. The servo motor 203 controls the feeding trolley 202 to continue to drag the second profile backward along the feeding roller conveyor until the second profile is completely dragged onto the feeding roller conveyor, completing the feeding operation of the second profile and starting to cut the second profile.

[0055] S500, during the second profile cutting process, the first workpiece and the remaining first profile material on the first roller station 103 of the roller support are cleaned.

[0056] After the material is unloaded, determine if all cutting tasks are completed. If not, repeat steps S100-S500. Figure 10 As shown, during the cutting process at the second roller conveyor station 104, after the material is unloaded at the first roller conveyor station 103, it is reloaded, and the above automatic loading and unloading operation is repeated until all cutting tasks are completed. If all cutting tasks have been completed, the operation is stopped.

[0057] Furthermore, the cleaning process of the first workpiece and the remaining first profile scrap on the first roller conveyor station 103, as well as the process of placing new profiles to be cut, can be completed when the second profile is being cut, thereby improving work efficiency.

[0058] By employing the aforementioned automatic profile loading and unloading control method, loading and unloading can be completed in the same area, greatly simplifying the mechanical structure and avoiding the need for handling equipment, such as overhead cranes or forklifts, to travel back and forth between the loading and unloading areas located on either side of the cutting mechanism, as is common in existing technologies. According to the technical solution of this invention, the handling equipment only needs to operate within the existing automatic loading and unloading mechanism area, thereby reducing handling time and equipment costs.

[0059] The automatic profile loading and unloading device of the present invention can be applied to any working environment where profiles need to be cut. It occupies little space and improves profile cutting efficiency because it can complete loading and unloading operations during the cutting process.

[0060] This invention also provides an automatic profile cutting system, including the aforementioned automatic profile loading and unloading device, a cutting mechanism 300, and employing the aforementioned automatic profile loading and unloading control method. The automatic loading and unloading mechanism is located at the outlet of the cutting mechanism, used to complete loading and unloading operations during the cutting process. A feeding roller conveyor is located at the loading outlet of the cutting mechanism, used to transport the profile during the cutting process. The cutting mechanism is used to perform the cutting operation on the profile. The cutting mechanism of this invention operates continuously during use, without occupying the machine's cutting time due to loading and unloading operations, thereby improving profile cutting efficiency.

[0061] The cutting mechanism of this invention includes a cutting torch, a chuck, multiple linear and rotary motion axes, and a drive mechanism. The chuck is used to hold the profile to be cut, and the drive mechanism controls the cutting torch to move along multiple linear and rotary motion axes, realizing three-dimensional CNC cutting with multiple degrees of freedom. By cutting with the movement of the cutting torch, the complexity requirements of the automatic profile loading and unloading device are simplified, and automatic loading and unloading operations are realized during the cutting process. Example

[0062] When there are no profiles on the feeding rollers of the automatic profile cutting system, and one of the two roller stations on the roller support (i.e., the first roller station) has a profile (i.e., the first profile) placed on it:

[0063] The first step is to determine whether the station where the profile is placed (i.e., the first roller conveyor station) is aligned with the outlet of the cutting mechanism. If not, move the roller conveyor support so that the first roller conveyor station is aligned with the outlet of the cutting mechanism.

[0064] The moving feeding trolley clamps the first profile on the first roller conveyor station and pulls it back until the entire first profile is dragged onto the feeding roller conveyor.

[0065] The second step is to start the machine's 3D CNC cutting mechanism to begin cutting.

[0066] The third step is to place a profile (i.e., the second profile) on the currently empty roller station (i.e., the second roller station) on the roller support during the cutting process.

[0067] Fourth, after the first profile is cut, move the feeding trolley to place the cut workpiece and remaining profile scrap completely on the first roller conveyor station. Move the roller conveyor support so that the second roller conveyor station is aligned with the discharge port of the cutting mechanism, and the first roller conveyor station with the cut workpiece leaves the discharge port.

[0068] The fifth step involves moving the feeding trolley to hold the second profile on the second roller conveyor station and pulling it back until the entire second profile is dragged onto the feeding roller conveyor.

[0069] Step 6: Start the cutting mechanism to begin cutting.

[0070] Step 7: During the cutting process, clean the first workpiece and the remaining material of the first profile that have been cut on the first roller table station on the roller table support, and place a profile on the station after cleaning.

[0071] Step 8: Return to step 4.

[0072] Start a loop from step four to step eight until all cutting tasks are completed. Example

[0073] When there are profiles on the feeding roller conveyor of the automatic profile cutting system, and both roller positions on the roller conveyor support are empty:

[0074] The first step is to start the machine's 3D CNC cutting mechanism to begin cutting.

[0075] The second step is to place a profile (i.e., the first profile) on the currently empty roller station (i.e., the first roller station) on the roller support during the cutting process.

[0076] Third, after the current profile is cut, the moving feeding trolley places the cut workpiece and the remaining profile scrap completely on the second roller conveyor station. The moving roller conveyor support aligns the roller conveyor station with the uncut profile (i.e., the first roller conveyor station) with the cutting mechanism's discharge port, while the second roller conveyor station with the cut workpiece moves away from the discharge port.

[0077] The fourth step is to move the feeding trolley to hold the first profile on the first roller conveyor station and pull it back until the entire first profile is dragged onto the feeding roller conveyor.

[0078] The fifth step is to start the cutting process by activating the three-dimensional CNC cutting mechanism of the automatic profile cutting system.

[0079] The sixth step is to clean the workpiece that has been cut on the second roller table station on the roller table support during the cutting process, and then place a profile on the station after cleaning.

[0080] Step 7: Go back to step 3.

[0081] Start a loop from step three to step seven until all cutting tasks are completed. Example

[0082] When there are profiles on the feeding roller conveyor, and one of the two roller conveyor stations on the roller conveyor support has a profile already placed there (i.e., the first roller conveyor station):

[0083] The first step is to determine whether the roller conveyor station without profiles (the second roller conveyor station) is aligned with the machine's discharge port. If not, move the roller conveyor support so that the second roller conveyor station is aligned with the discharge port of the cutting mechanism.

[0084] The second step is to start the cutting process by activating the three-dimensional CNC cutting mechanism of the automatic profile cutting system.

[0085] Third, after the current profile is cut, move the feeding trolley to place the cut workpiece and the remaining profile scrap completely on the second roller conveyor station. Move the roller conveyor support so that the roller conveyor station with the uncut profile (i.e., the first roller conveyor station) is aligned with the machine's discharge port, and the roller conveyor station with the cut workpiece moves away from the discharge port.

[0086] The fourth step involves moving the feeding trolley to grip the uncut profile at the first roller conveyor station and pull it back until the entire profile is dragged onto the feeding roller conveyor.

[0087] The fifth step is to start the cutting process by activating the three-dimensional CNC cutting mechanism of the automatic profile cutting system.

[0088] The sixth step is to clean the workpiece that has been cut on the second roller table station on the roller table support during the cutting process, and then place a profile on the station after cleaning.

[0089] Step 7: Go back to step 3.

[0090] Start a loop from step three to step seven until all cutting tasks are completed. Example

[0091] When there are profiles on the feeding roller conveyor, and one of the two roller conveyor stations (i.e., the second roller conveyor station) on the roller conveyor support still has a cut workpiece that has not been cleaned:

[0092] The first step is to check whether the roller conveyor station without profiles (i.e., the first roller conveyor station) is aligned with the material outlet of the cutting mechanism. If not, move the roller conveyor support so that the first roller conveyor station is aligned with the material outlet of the machine.

[0093] The second step is to start the cutting process by activating the three-dimensional CNC cutting mechanism of the automatic profile cutting system.

[0094] The third step is to clean the cut workpieces on the roller conveyor station (i.e., the second roller conveyor station) that are not currently being cut, and then place a profile on that station after cleaning.

[0095] Fourth step: After the current profile is cut, move the feeding trolley to place the cut workpiece and remaining profile scrap completely on the first roller conveyor station. Move the roller conveyor support so that the second roller conveyor station with the uncut profile is aligned with the machine's discharge port, and the first roller conveyor station with the cut workpiece moves away from the discharge port.

[0096] The fifth step involves moving the feeding trolley to grip the uncut profile at the second roller conveyor station and pull it back until the entire profile is dragged onto the feeding roller conveyor.

[0097] Step 6: Start the cutting process using the 3D CNC cutting mechanism of the automatic profile cutting system.

[0098] Step 7: Go back to step 3.

[0099] Start a loop from step three to step seven until all cutting tasks are completed.
