Description

Technical Field

[0001] The utility model relates to the field of plate handling devices, in particular to a large-size plate handling device. Background Art

[0002] Gantry milling machine, also known as gantry milling machine, is a milling machine with a portal frame and a horizontal long bed. It is suitable for processing the plane and inclined surfaces of large workpieces in batch and mass production. When the gantry milling machine processes large-sized steel plates, plate handling equipment is required to transport the plates.

[0003] The existing large-size plate handling device includes a support frame that can move in the horizontal direction and a negative pressure suction frame that can be raised and lowered in the vertical direction. When the gantry milling machine processes some large-size plates that require double-sided milling, the large-size plate handling device will lift the plate with the top surface processed to the turning device, turn it 180 degrees, and then lift it back to the gantry milling machine for bottom surface processing of the plate.

[0004] With regard to the above-mentioned related technologies, the existing large-size plate handling device needs to cooperate with the flipping device to realize the flipping of the plate after the gantry milling machine has processed the top surface of the plate, and the handling device takes a lot of time to lift the large-size plate between the flipping device and the gantry milling machine, which affects the processing efficiency. The large-size plate lifted from the gantry milling machine needs to be positioned after being flipped and returned to the gantry milling machine to avoid the plate being unable to be placed in the original position after being flipped. In summary, the existing large-size plate handling device is difficult to conveniently flip the plate and put it back into the gantry milling machine. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a large-size plate handling device to solve the technical problem that the existing large-size plate handling device is difficult to conveniently flip the plate and put it back into the gantry milling machine.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a large-size plate handling device, comprising a mobile frame, two lifting beams that can be lifted up and down are arranged between the mobile frames, the lifting beams are provided with a mobile platform that slides along the length direction, a rotating frame is rotatably connected between the two mobile platforms, and a lifting frame facing the ground and parallel to the ground is arranged above the rotating frame in the middle of the two lifting beams, and both the rotating frame and the lifting frame are provided with a holding structure for holding large-size plates.

[0007] By adopting the above technical solution, a holding structure for holding the plate is provided on both the lifting frame and the rotating frame. After the moving frame moves to above the plate, the plate can be quickly turned over by only lifting the lifting beam and flipping the rotating frame. Moreover, since the moving frame does not move, the plate can be placed back to its original position more accurately after turning over, which is convenient for the continuation of subsequent processing.

[0008] The utility model is further configured such that the two lifting beams are parallel to each other and can be lifted and lowered synchronously.

[0009] By adopting the above technical solution, the two lifting beams are parallel to each other, which can keep the plate body in a horizontal state, and is conducive to the holding structure of the plate body.

[0010] The present invention is further configured such that the width of the rotating frame is the same as the width of the lifting frame, and the length of the lifting beam is greater than three times the width of the lifting frame.

[0011] By adopting the above technical solution, the lifting frame is prevented from interfering with the rotating frame during the process of sucking the plate body and lowering the height downward.

[0012] The utility model is further configured such that a plurality of groups of vertically upward telescopic columns are fixedly connected to a side of the lifting beam away from the moving platform, and the telescopic columns include a fixed part and a telescopic part, wherein the fixed part is fixedly connected to the lifting beam, and the top end of the telescopic part is fixedly connected to the edge of the lifting frame.

[0013] By adopting the above technical solution, the telescopic column is used to further control the lifting of the lifting frame. When the rotating frame flips the plate body and sends it to the bottom of the lifting frame, the lifting frame lowers its height to stably hold the surface of the plate body to be processed.

[0014] The present invention is further configured such that the lifting frame and the rotating frame are both provided with a plurality of vacuum suction cups at intervals along the length direction.

[0015] By adopting the above technical solution, multiple groups of vacuum suction cups arranged at intervals are used to stably hold large-sized plates.

[0016] The present invention is further configured such that a driving structure for driving the movable platform to move along its own length direction is provided in the lifting beam, and a driving structure for driving the rotating frame to rotate is provided in the movable platform.

[0017] By adopting the above technical solution, the movable platform can drive the rotating frame to rotate while moving in the lifting beam.

[0018] The present invention is further configured such that the rotating frame can be parallel to the lifting frame after rotation, and the vacuum suction cups therebetween maintain a state of facing each other or in the same direction.

[0019] By adopting the above technical solution, the transfer of plates between the lifting frame and the rotating frame can be smoother.

[0020] In summary, the present invention has the following beneficial effects:

[0021] The utility model installs a movable platform which can slide along the length direction of the lifting beam on the lifting beam of the movable frame, and arranges a lifting frame facing downward in the middle of the lifting beam, and a holding structure for holding the plate is provided on the lifting frame and the rotating frame. After the movable frame moves to above the plate, the plate can be quickly turned over only by lifting the lifting beam and flipping the rotating frame. Moreover, since the movable frame does not move, the plate can be placed back to its original position more accurately after being turned over, which is convenient for continuing the subsequent processing.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] The following describes an embodiment of the present invention based on its overall structure.

[0031] Example 1

[0032] A large-size plate handling device, such as Figure 1-6 The lifting platform 3 is a vertical cam 2 that is mounted on the support frame 1 and is used for lifting and lowering the lifting platform 1. The lifting platform 3 is a vertical cam 2 that is used for lifting and lowering the lifting platform 1. The lifting platform 3 is a vertical cam 2 that is used for lifting and lowering the lifting platform 1.

[0033] See also Figure 3-6 The width of the rotating frame 4 is the same as that of the lifting frame 6, and the length of the lifting beam 2 is greater than three times the width of the lifting frame 6, so as to avoid interference between the lifting frame 6 and the rotating frame 4 during the process of holding the plate body 7 and lowering the height, so that the lifting frame 6 can smoothly return the flipped plate body 7 to its original position. Both the lifting frame 6 and the rotating frame 4 are provided with multiple sets of vacuum suction cups at intervals along the length direction, and multiple sets of vacuum suction cups arranged at intervals are used to stably hold large-sized plates.

[0034] See also Figure 1-4 The gear at the output end of the driving motor is engaged with the toothed belt to drive the movable table 3 and the lifting beam 2 to move along the length direction. The driving structure is provided in the movable table 3 to drive the rotating frame 4 to rotate. Specifically, the movable table 3 is provided with a driving structure for driving the rotating frame 4 to rotate. Specifically, the rotating shaft of the rotating frame 4 is provided with an outer gear ring in the movable table 3, and the movable table 3 is provided with another driving motor with a gear at the output end. The gear at the output end of the driving motor is engaged with the outer gear at the end of the rotating shaft of the rotating frame 4, thereby driving the rotating frame 4 to rotate in a controlled manner, so that the movable table 3 can move in the lifting beam 2 while also driving the rotating frame 4 to rotate. After the rotating frame 4 rotates, it can be parallel to the lifting frame 6, and the vacuum suction cups between the two remain in a facing state or in the same direction, so that the plate transfer between the lifting frame 6 and the rotating frame 4 can be more stable.

[0035] Example 2

[0036] A large-size plate handling device, such as Figure 1-6As shown, based on the embodiment 1, the difference from the embodiment 1 is that a plurality of groups of vertically upward telescopic columns 5 are fixedly connected to the side of the lifting beam 2 away from the moving platform 3. Specifically, the telescopic columns 5 are hydraulic telescopic columns, which can maintain stability during lifting. The telescopic columns 5 include a fixed part and a telescopic part, wherein the fixed part is fixedly connected to the lifting beam 2, and the top of the telescopic part is fixedly connected to the edge of the lifting frame 6. The telescopic columns 5 are used to further control the lifting and lowering of the lifting frame 6. When the rotating frame 4 flips the plate body 7 and sends it to the bottom of the lifting frame 6, the lifting frame 6 lowers its height to stably hold the surface of the plate body 7 to be processed.

[0037] The working principle of the present invention is as follows: the mobile frame 1 moves to the top of the plate body 7 of the gantry milling machine, the suction cup of the rotating frame 4 is facing downward at this time, the lifting beam 2 is lowered to allow the suction cup on the rotating frame 4 to hold the processed surface of the plate body 7, and the lifting beam 2 is raised while the mobile platform 3 moves toward the end of the lifting beam 2. At the same time, the rotating frame 4 is driven by the driving structure to rotate and turn over. In the process of turning over the plate body 7, the rotation speed of the rotating frame 4 and the sliding position of the moving platform 3 are controlled to prevent the plate bodies 7 of different sizes from colliding with the mobile frame 1 or the lifting and lowering. The lifting frame 6 is controlled by the telescopic column 5 to descend, and the suction cup on the lifting frame 6 holds the surface of the plate body 7 to be processed, and then the suction cup on the rotating frame 4 is released from the holding state. The moving platform 3 controls the rotating frame 4 to move toward the end of the lifting beam 2 to avoid the lifting frame 6, and then the height of the lifting beam 2 is lowered and the lifting frame 6 continues to lower its height, and the flipped plate body 7 is steadily placed back to its original position on the gantry milling machine.
