[0051] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] The present invention provides a double-beam gantry device for profile sorting, see Figure 1The difference between the present invention and the prior art lies in that: the double-beam gantry device for profile sorting includes a track system, the track system includes two parallel main tracks 1, a main beam unit 6 is provided on the track system, and the main beam unit 6 is slidably connected with the main track 1 by end beam components 5 arranged on both sides of the main beam unit; a movable walking trolley 10 is provided on the main beam unit, a lifting mechanism is provided on the walking trolley, a rotating unit is provided at the lower part of the lifting mechanism, an electromagnetic beam unit is provided below the rotating unit, and a profile tray 22 is provided between the two main tracks.

[0053] When in use, the device of the present invention can be used to effectively sort the profiles and load the profiles into corresponding profile trays to correspond to different profile usage segments. Specifically, the profile is passed through a lifting mechanism and a rotating unit to complete the direction of the profile on the segment and the precise position in the Y direction, thereby improving the efficiency of automatic welding of the profiles; for profiles of different specifications, the height position of the electromagnetic beam is adjusted through the lifting mechanism to match profiles of various specifications. The entire process of profile loading is fully automatic. Through the model analysis of the sheet body, the specifications, position, and sequence information of the profile are extracted, imported into the control system, the equipment operation is executed, and the transfer of the profile into the pallet is completed; when the profile is loaded into the profile pallet, the position in the X direction is precisely positioned by driving the main beam unit through the end beam component. At the same time, the gantry adopts a double-beam structure to ensure its stability and stability.

[0054] Example 1

[0055] In this embodiment, a track system is included, which includes two main tracks 1 arranged in parallel. A main beam unit 6 is provided on the track system. The main beam unit is slidably connected with the main track by end beam components 5 arranged on both sides of the main beam unit. A movable trolley 10 is provided on the main beam unit, and a lifting mechanism is provided on the trolley. A rotating unit is provided at the bottom of the lifting mechanism, and an electromagnetic beam unit is provided below the rotating unit. A profile tray 22 is provided between the two main tracks.

[0056] Specifically, there are two sets of end beam components 5, which are symmetrically arranged at both ends of the main beam unit 6. Each end beam component is provided with an end beam servo drive mechanism 4, an end beam wheel matched with the end beam servo drive mechanism, and a buffer matched with the end beam wheel. The main beam unit is accurately moved along the main track through the end beam components, and the precise positioning of the whole gantry is achieved.

[0057] The main beam unit includes two sets of main beams arranged in parallel, each of which is provided with a main beam guide rail 7 and a main beam rack 8 matched with the main beam guide rail, and a pull rod 9 is provided between the two main beam guide rails. A trolley 10 that can slide along the main beam guide rail is provided on the main beam guide rail. The trolley includes a body, a servo reduction drive mechanism 11 provided on the body, and a wheel component 12 provided under the body. The wheel component cooperates with the main beam rack. By moving the trolley along the main beam guide rail, precise positioning and control of the profile running in the Y direction can be achieved.

[0058] Specifically, the main beam unit 6 adopts a double-beam structure, and the main beam deflection and bending stress can be increased by more than 60%, which can not only ensure the accuracy of its own mechanism, but also improve the accuracy of the equipment during horizontal, up and down and rotation operations. The horizontal movement accuracy can reach within 0.5mm, and the rotation accuracy can reach within 0.1°. At the same time, a cylindrical pull rod 9 is used between the double beams of the main beam, which can not only effectively ensure the spacing between the double beams, but also improve the strength of the overall double beams, providing a stable working environment for the rotation of the lifting unit, and avoiding the deviation of the profile placement position caused by the shaking of the equipment itself and the tangential force generated when the profile is rotated during lifting and rotation, thereby improving the sorting efficiency.

[0059] The lifting mechanism includes a guide column 16 and a lifting guide rail 14 arranged along the guide column; the rotating unit includes a rotating servo reduction drive mechanism 17 arranged on the lifting guide rail and a turntable bearing unit 18 connected to the rotating servo reduction drive mechanism. The turntable bearing unit is connected to the electromagnetic beam unit to drive the electromagnetic beam unit to rotate ±180°. The electromagnetic beam unit includes a rotating electromagnetic beam 19, an electromagnet unit arranged at the bottom of the rotating electromagnetic beam, and an electromagnet control unit for controlling the electromagnet unit. The electromagnetic beam unit is mainly used for grabbing and placing profiles. A rack and a track adjustment mechanism are respectively provided on each main track. The power supply system includes a drag chain and a support frame to provide support for the energy supply pipeline of the double-beam gantry device for profile sorting. The profile tray is used to place the profiles that have been milled and cut, and is used for the automatic welding station of the profile of the plane line.

[0060] The bearing turntable unit 18 here is an external tooth structure, and the angle of each external tooth is 2.17°; one end of the screw transmission unit passes through the guide column and is fixed by a nut, and the other end is connected to the traveling trolley.

[0061] Specifically, if Figure 5It is a structural diagram of the lifting mechanism, including a lifting servo drive mechanism 13, a lifting guide column 14, a screw transmission unit 15, a guide column 16, a rotary servo reduction drive mechanism 17 and a turntable bearing unit 18. The screw transmission unit 15 is provided with four positive and negative guide rails and an eight-slider design, that is, each guide rail is provided with two sliders that cooperate with the guide rail, and the four positive and negative guide rails are arranged parallel to each other. Compared with the existing technology, the precision and accuracy are improved by more than 55%, the seismic resistance and stability of the mechanism are greatly improved, and the sorting of profiles can be more accurate and efficient; at the same time, the quasi-single-axis drive design of the lifting unit can not only effectively improve the tensile strength of its own mechanism by 20%, but also has extremely low processing and maintenance costs, effectively expanding the use scenarios of the equipment.

[0062] The design of the heavy-load slider and high-magnetic force electromagnet of the lifting unit enables the equipment to sort profiles within 10 tons, while also taking into account profiles of relatively small size, and has a wide range of applications. The lifting unit can achieve 4 degrees of freedom in space, namely the X direction, Y direction, Z direction and XY plane rotation direction. The lifting unit can achieve simultaneous movement of four degrees of freedom, which greatly improves the efficiency of sorting; when sorting profiles, the lifting mechanism can be first moved in the X direction close to the center of the profile, so that the force point of the lifting mechanism rotation coincides with the center of the profile, which can ensure the stability of the profile and the equipment during the rotation process. Since the four degrees of freedom of the equipment move simultaneously, it is necessary to ensure that formula 1.1 can make the sorting operation efficient and smooth.

[0063] V x ≤0.82V y

[0064] Vy≤0.75V z

[0065]

[0066] Where V x V is the moving speed of the equipment in the X direction. y Equipment moving speed in Y direction, V z V is the moving speed of the equipment in the Z direction. θ is the rotation speed of the lifting mechanism, and Max{Lx, Ly} is the maximum distance the equipment can move in the X and Y directions.

[0067] At the same time, in order to improve the sorting efficiency of profiles, the movement mode and speed in degrees of freedom were analyzed and studied. The results show that the rotation time and rotation accuracy in the key technical indicators have a great influence on the sorting movement cycle and placement accuracy of profiles. The sorting cycle of profiles is proportional to the rotation speed. The faster the rotation speed, the faster the sorting cycle. The specific formula is as follows:

[0068]

[0069] where t y is the time required for the equipment to move in the Y direction, t θ is the rotation time required for the lifting mechanism, is the total time required for profile sorting, t k It is the motor response time and other equipment consumption time.

[0070] Furthermore, in order to increase the rotation speed of the lifting mechanism, a high-precision external gear bearing turntable unit is designed. The external gear of the bearing turntable unit has a rotation angle of 2.17° and a rotation accuracy of 0.1°, which can effectively increase the sorting speed during the stable operation of the equipment. The equipment of the present invention can complete the sorting of profiles with a maximum length of 12M and can work continuously, and the sorting rate is 500% higher than that of manual work.

[0071] Example 2

[0072] This embodiment describes a method for using a double-beam gantry device for profile sorting, including the following steps: a. Automatically pick up profiles. The main beam unit slides along the main track to the profile picking position through the end beam component. The electromagnetic beam unit reaches the profile picking position through the cooperation of the lifting mechanism and the rotating unit to complete the profile picking work; b. Adjust the direction of the profile in the segment. The electromagnetic beam unit is driven to rotate by the rotating unit. The profile is turned to the required direction of the sheet, so that the verticality range difference between the profile and the main track is ±1 degree; c. Adjust the position of the profile in the Y direction. The electromagnetic beam moves along the Y direction through the movement of the walking trolley, so that the profile reaches the required position of the sheet in the Y direction; d. The profile is automatically loaded into the tray. After the position of the profile on the sheet is confirmed, the electromagnetic beam unit puts the profile into the specified position on the profile tray through the movement of the main beam unit and the lifting and lowering movement of the lifting system, and the electromagnetic beam unit returns to the initial position.

[0073] Specifically, in step a, the control system of the double-beam gantry device for profile sorting receives the profile information list from the workshop management system, including the position information of the profile on the segment, and drives the device to automatically pick up the material through these instructions. Since this part is the prior art, its specific operation process will not be repeated here.

[0074] The main beam unit 6 moves to the profile picking position through the end beam servo drive mechanism 4, and then the lifting servo drive mechanism 13 drives the rotating electromagnetic beam 19 to descend to the profile position. This mechanism can accurately determine the required height of the rotating electromagnetic beam 19 for each specification of profile according to different profiles. The rotating electromagnetic beam 19 picks up the profile after milling and cutting. The rotating electromagnetic beam 19 rises to the specified position, and then moves to the initial position through the end beam component 5.

[0075] In step b, after the rotating electromagnetic beam 19 reaches the initial position, the profile sorting device control system drives the rotating electromagnetic beam 19 to rotate 180 degrees (±180) according to the profile direction specified in the profile information list, and the rotating servo reduction drive mechanism 17 places the profile in the same direction as the sheet body, and accurately ensures the perpendicularity of the profile to the main track 1 of ±0.1 degree.

[0076] In step c, after the direction of the profile is adjusted, the servo reduction drive mechanism 11 drives the walking trolley 10, which is accurately driven by the gear rack and carries the rotating electromagnetic beam 19 to move back and forth in the Y direction, and finally determines the Y direction position of the profile on the sheet.

[0077] In step d, after the confirmation of the profile on the sheet is completed, the end beam servo drive mechanism 4 drives the gantry to move, and at the same time the rotary servo reduction drive mechanism 17 drives the rotary electromagnetic beam 19 to rise and fall, and the profile is placed in the specified position on the profile tray, which is strictly consistent with the order specified in the profile information list. After the placement is completed, the electromagnetic beam 19 returns to the initial position, waiting for the next profile to be grasped, adjusted, placed in the tray, and returned to zero.

[0078] The above content is a further detailed description of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to the above descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
