Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy processing auxiliary equipment, in particular to a gantry palletizing device. Background Art

[0002] Before palletizing, the palletizer needs to neatly arrange the products on the palletizer before palletizing. After the metal bar stock is processed, such as aluminum alloy bar stock: the aluminum alloy long bars are stacked, usually stacked in a triangular cross-section, and the weight of the aluminum bars is relatively heavy. Ordinary fixtures cannot meet the requirements. The existing palletizers cannot ensure the neatness of the products before palletizing, which easily leads to unstable stacked products. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is that currently, the palletizer cannot ensure the neatness of the products before palletizing, and there is no suitable fixture for palletizing and stacking aluminum bars.

[0004] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0005] A gantry palletizing device includes a gantry. Symmetrically fixed to both sides of the top of the gantry near its two sides are walking guide rails arranged along the "Z" axis direction. A moving frame driven by a walking driving mechanism and moving along the walking guide rails is arranged on the walking guide rails, and there is at least one moving frame;

[0006] At the bottom of the moving frame and inside the gantry and near the symmetric position of the gantry, at least a pair of fixing frames perpendicular to it are fixedly connected. Guide rails a are fixedly connected to opposite sides of the fixing frames. A fixture moving along the guide rails a is arranged on the guide rails a. A servo driving device for driving the moving frame to move up and down is arranged at the position of the moving frame where the fixing frames are located. The servo driving device includes a servo motor and a ball screw used in cooperation with it;

[0007] The fixture includes a clamp seat used in cooperation with the guide rails a. A clamping seat driven by a screw rod mechanism is arranged on the clamp seat, and a supporting seat is also arranged on the clamping seat.

[0008] Further, the clamp seat includes a panel and a bottom plate fixed to the outer surface of the panel and perpendicular to it. Reinforcing plates are also fixedly connected to both sides of the panel and the bottom plate. A guide rail is fixedly connected to the top of the bottom plate. The cross-section of the clamping seat is "L" shaped, and the clamping seat is driven by a screw rod mechanism composed of a motor, a screw rod, and a base to move along the guide rail;

[0009] L-shaped limit seats are fixedly connected to positions near both sides of the top of the supporting seat. The L-shaped limit seats are clamped on both sides of the clamping seat and driven by a cylinder arranged on the clamping seat.

[0010] Furthermore, the top of the bracket located on the outer side of the clamping seat is concave.

[0011] Working principle and beneficial effects: By controlling the servo motor to drive the ball screw to rotate, the clamp seat is driven to slide along the guide rail a and move along the Y-axis direction. After the clamp seat is driven to move to the end of the bar, the screw mechanism drives the clamp seat to extend and reset. The clamp seat extends to align the bar between it, and the support seat lifts the end of the bar, and then controls the servo motor to drive the clamp seat to lift, and then controls the travel drive mechanism to drive the mobile frame to move along the Z-axis to complete the stacking of the bar.

[0019] like Figures 1-4 As shown,

[0020] A gantry palletizing device includes a gantry 1. At symmetric positions near both sides of the top of the gantry 1, there are fixedly connected walking guide rails 2 arranged in the "Z" - axis direction. On the walking guide rails 2, there is a moving frame 3 driven by a walking drive mechanism and moving along the walking guide rails 2. There is at least one moving frame 3. At the bottom of the moving frame 3 and inside the gantry 1 and near the symmetric position of the gantry 1, there are fixedly connected at least a pair of fixing frames 4 perpendicular to it. On opposite sides of the fixing frames 4, there are fixedly connected guide rails a5. On the guide rails a5, there is a clamp moving along the guide rails a5. At the position of the moving frame 3 corresponding to the fixing frames 4, there is a servo - drive device for driving the moving frame 3 to move up and down. The servo - drive device includes a servo motor 6 and a ball screw used in cooperation with it.

[0021] In the present utility model, by controlling the servo motor 6 to drive the ball screw to rotate, the clamp seat 7 is driven to slide along the guide rail a5 and move in the Y - axis direction. Among them, a fixed seat rotatably connected to the ball screw is fixedly connected to the clamp seat 7. After the clamp seat 7 is driven to move to the end of the bar stock, the screw mechanism drives the clamping seat 8 to extend and reset. When the clamping seat 8 extends, it can align the bar stock located between them, and the support seat lifts the end of the bar stock. Then, control the servo motor 6 to drive the clamp seat 7 to rise, and then control the walking drive mechanism to drive the moving frame to move along the Z - axis direction to complete the stacking of the bar stock.

[0022] The clamp includes a clamp seat 7 used in cooperation with the guide rail a5. On the clamp seat 7, there is a clamping seat 8 driven by a screw mechanism. On the clamping seat 8, there is also a support seat 9. The clamp seat 7 includes a panel 71 and a bottom plate 72 fixed to the outer surface of the panel 71 and perpendicular to it. Reinforcement plates are fixedly connected to both sides of the panel 71 and the bottom plate 72. A guide rail 73 is fixedly connected to the top of the bottom plate 72. The cross - section of the clamping seat 8 is "L" - shaped. The clamping seat 8 is driven by a screw mechanism composed of a motor 74, a screw 75 and a base to move along the guide rail 73. At positions near both sides of the top of the support seat 9, there are fixedly connected L - shaped limit seats. The L - shaped limit seats clamp both sides of the clamping seat 8 and are driven by a cylinder 10 arranged on the clamping seat 8. When aligning the bar stock, the support seat 9 is in a contracted state. After alignment and clamping, control the cylinder 10 to drive the support seat 9 to extend and lift the bar stock. In order to prevent the bar stock from rolling after being lifted, the support seat 9 is improved. Specifically, the top of the support seat 9 outside the clamping seat 8 is concave.
