An automatic push-pull device for a comprehensive picking unit and a control method thereof

Abstract

The invention discloses an automatic push-pull device for a comprehensive picking unit and a control method thereof. The device includes a frame, a fluent strip, and a linear guide rail conveying device. A fluent strip is installed on both sides of the upper surface of the frame, and a linear guide rail is installed between the two fluent strips for conveyance. The device is equipped with a positioning module on the linear guide rail handling device. Under the control of the control device, the efficient cooperation between the lifting platform of the stacker and the positioning module is realized to meet the movement of heavy materials. At the same time, the structure of the two-stage transmission The combination of the first-stage motor for fast movement and the fine-tuning of the second-stage motor can realize the movement process of transportation more efficiently, and realize the coordination of fast movement and accurate movement at low cost.

Description

Technical field [0001] The present invention belongs to the field of material picking technology, and specific relates to a combined picking unit automatic push-pull and its control method. Background technique [0002] With the development of the times, material transportation is one of the ways to improve work efficiency. Material delivery is the first to use an overhead cableway to deliver a scattered material; then the conveyor conveyor of various modern structures appears. As early as early in the UK, a spiral conveyor appeared in the United States, a steel belt conveyor appeared in Switzerland, an inertial conveyor in the UK and Germany, and more. Since then, the conveyor conveyor is influenced by mechanical manufacturing, motor, chemical and metallurgical industrial technological progress, continuous improvement, gradually by completing the transfer inside the workshop, and has been completed within the enterprise, and even the materials between enterprises and even cities...

AI Technical Summary

Problems solved by technology

[0005] 1. Existing material handling mostly uses conveyor belts or robotic arms for transportation. Once the conveyor belt slips on the conveyor belt or causes displacement due to acceleration, the moving distance is likely to be inaccurate and the item falls; and the cost of the mechanical arm with the displacement system It is too high, the structure is complicated, and maintenance is difficult. Both of them are not practical for heavy items. If the item is too heavy, the inertia will be high, the item will slip, and the mechanical arm is difficult to hold and weigh, etc.

[0006] 2. The movement of the existing material handling device is difficult to achieve the coordination of fast movement and accurate movement at low cost. Fast movement means that it needs extremely fast reaction speed to achieve accurate stop, or slow movement to achieve long reaction time Accurate stop, otherwise it will cause a large error in the mobile position
