Description

Technical Field

[0001] This utility model relates to the field of automated handling technology, specifically to a palletizing workbench. Background Technology

[0002] In the traditional printing industry, the production of printed materials typically relies heavily on manual labor, including palletizing and handling. With increasing printing speed and output, manual palletizing is not only labor-intensive but also inefficient, prone to human error, leading to damage and quality issues. To improve production efficiency and ensure product quality, automated palletizing technology is increasingly being applied in the printing industry.

[0003] However, most current automated palletizing equipment uses a gripping structure, where printed materials are placed on a conveyor belt or the ground and then gripped by a robotic arm. Due to the characteristics of the paper, printed materials are easily deformed during the gripping process, leading to them falling off. Some automated palletizing equipment uses a bottom-supporting clamping mechanism, but the robotic arm design is complex, requiring the printed materials to be lifted to a certain height before the bottom-supporting mechanism can extend into the bottom of the printed materials to complete the clamping action.

[0004] Based on this, a palletizing workbench designed to lift printed materials is created, which, combined with a bottom-supporting robotic arm structure, simplifies the robotic arm structure and improves handling efficiency. Utility Model Content

[0005] To address the problems existing in the background art, this utility model provides a palletizing workbench, which includes:

[0006] The main body includes a table and a support frame installed below the table. The table has roller holes in row a and column b, and ejection holes in row c and column d.

[0007] A roller unit, the roller unit including a wheel axle and a roller mounted on the wheel axle, the roller being disposed in a roller hole, the top of the roller being higher than the roller hole;

[0008] The lifting mechanism includes an ejector cylinder mounted on a support frame. The ejector cylinder is equipped with a telescopic rod, and a tray is connected to the end of the telescopic rod. The tray is equipped with ejector rods in row c and column d. The ejector rods can be ejected upward through the ejector hole under the action of the ejector cylinder.

[0009] In the preferred embodiment, a=4 and b=4.

[0010] In the preferred scheme, c=7 and d=3.

[0011] In the preferred embodiment, the distance between two adjacent rows of ejector holes is not less than 2 cm.

[0012] In a preferred embodiment, a hanging plate is installed on the bracket, and a horizontal baffle and a vertical baffle are also installed on the platform of the main body.

[0013] In a preferred embodiment, a motor is also installed on the support frame, and the motor is connected to a roller units via a synchronous belt to drive the rollers of the roller units to rotate.

[0014] The beneficial effects achieved by this utility model are as follows:

[0015] First, this utility model is designed with a lifting mechanism. By combining an ejector cylinder and a push rod, the printed matter is automatically lifted, avoiding the complicated process of traditional robotic arms that require lifting the printed matter to a certain height before clamping it, thereby improving the handling efficiency.

[0016] Secondly, this utility model adopts a combination of roller unit and lifting mechanism, which can achieve transportation by lifting the bottom without directly contacting the surface of the printed matter, effectively reducing the problem of deformation and damage to the printed matter caused by gripping.

[0017] Third, with the support structure of the bottom-mounted robotic arm, the design of this palletizing workbench eliminates the need for a complex gripping mechanism. A simple clamping device is all that's needed to complete the handling task, greatly reducing the manufacturing cost and maintenance difficulty of the robotic arm.

[0018] Fourth, by driving the rollers with a motor, the position of the printed material can be automatically adjusted to align with the ejector hole, further improving the level of automation and reducing the need for manual intervention. Attached Figure Description

[0031] In this embodiment, the automated palletizing and handling process is as follows:

[0032] Initial state:

[0033] The items or printed materials to be transported are conveyed to the palletizing workbench via a conveyor belt. The roller 22 is driven by motor 4 to rotate, which adjusts the position of the printed materials so that they are in the center of all the ejection holes 12, so that the ejector rod 33 can lift the printed materials upward.

[0034] The hanging platform 73 is connected to the robotic arm, and the movement of the robotic arm allows the L-shaped boom 71 to approach the printed materials that need to be stacked.

[0035] The ejector cylinder 31 pushes the ejector rod 33 upward, thus lifting the printed material.

[0036] When the magnetic coupler rodless cylinder 76 is started, the slider slides along the cylinder barrel, driving the lower clamp 77 to move downward to below the printed matter being transported. The lower clamp 77 is provided with several racks according to the arrangement of the ejector holes 12, and there are gaps between the racks. The ejector rod 33 passes through the gaps between the racks, so that the lower clamp 77 is located directly below the printed matter.

[0037] Subsequently, the telescopic shaft of cylinder 74 extends, pushing the upper clamp 75 downward to clamp the printed material together with the lower clamp 77. Under the combined action of the upper clamp 75 and the lower clamp 77, the printed material is firmly clamped, and due to the presence of the spring, a certain amount of cushioning and adaptive clamping force can be provided to accommodate printed materials of different sizes or shapes.

[0038] After ensuring that the printed material is securely gripped, the entire robotic arm 7, including the L-shaped arm 71 and the gripped printed material, can be lifted or transported to the target location.

[0039] Upon reaching the target position, the telescopic shaft of cylinder 74 retracts, the upper clamp 75 moves upward, separates from the lower clamp 77, and releases the printed material.

[0040] The slider of the magnetic coupler rodless cylinder 76 may move upward simultaneously or subsequently, bringing the lower clamp 77 back to its initial position.

[0041] After release, the palletizing workbench returns to its initial state, ready for the next gripping and handling operation.

[0042] The present invention includes a hanging plate 73 and a connecting column, and a spring is installed on the outside of the connecting column to further stabilize the clamping process or provide additional balance support.

[0043] The dual magnetic coupler rodless cylinder 76 features a bottom-support design, which enhances clamping stability and strength, ensuring effective clamping even for heavier printed materials.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
