Description

Automatic storage trolley handling device

The present invention provides a technical field of automatic storage, especially an automatic storage trolley handling device, in which the loading trolley does not need to be guided by a bottom rail, which greatly increases the freedom of movement. The whole machine uses electric transmission and does not need to add hydraulic equipment, which avoids oil leakage, equipment and weight reduction. In addition, the loading trolley can be assembled by using a general commercial chain to perform lifting movements, which effectively reduces costs and is easy to assemble, integrate and maintain.

According to the patent application No. 107108849 of the invention of "Connection structure of automatic storage system", the content generally mentions that it has at least one running channel, and the running channel is paved with a bottom rail. However, the preparation and laying of the bottom rail is a large project, which will inevitably increase the time and cost. On the other hand, the spider transporter runs on it, which also means that the spider transporter cannot drive in the position without the bottom rail, which greatly reduces the freedom of the transporter. Then, each climbing member is pushed out synchronously through the telescopic device, so that each climbing member is combined with the climbed members on the shelves on both sides at the same time. The "retractable device is a hydraulic cylinder", but hydraulic and electric motors use different systems, so installing two systems on a single transport vehicle increases the difficulty of maintenance. Hydraulic also requires a fuel tank, a booster oil supply device, pipelines and hydraulic cylinders, etc. It consumes a lot of electricity and must have a dedicated power supply device, which inevitably increases its equipment, volume, weight and cost. In addition, two U-shaped guide rails are installed upright on the shelf. The two U-shaped guide rails are arranged opposite to each other and appropriately spaced so that a longitudinally extending lifting groove is formed between the two U-shaped guide rails. The lifting groove is provided with a plurality of links fixed on the two U-shaped guide rails. The links are connected by two 8-shaped metal plates, and "can be fixed on the U-shaped guide rails." The two U-shaped rails are clamped by the metal plate and the chain link. Therefore, it is understood that the U-shaped rail needs to have many holes, and most of the chain links are fixed to the U-shaped rail one by one, so there is no such commercial product on the market. If maintenance is required, it must be customized. The waiting time is longer than the maintenance time, which is not cost-effective.

Therefore, in view of the problems existing in the above-mentioned knowledge structure, how to develop a more ideal and practical innovative structure is what consumers are eagerly looking forward to, and it is also the goal and direction that relevant industries must work hard to develop breakthroughs.

In view of this, the inventor, based on his many years of experience in manufacturing, developing and designing related products, has designed and carefully evaluated the above-mentioned goals and finally obtained this invention which is truly practical.

The main purpose of the present invention is to provide an automatic storage trolley handling device, in which the trolley does not need to be guided by a bottom rail, which greatly increases the freedom of movement. The entire machine uses electric transmission and does not require additional hydraulic equipment, eliminating oil leakage, equipment and weight reduction. In addition, the trolley can be assembled using a general commercial chain to perform lifting movements, effectively reducing costs and being easy to assemble, integrate and maintain.

To achieve the above-mentioned purpose, the present invention provides an automatic storage trolley transport device, which includes: at least one running channel, with cargo racks on both sides of the running channel, and at least one cargo trolley, which can be equipped with an automatic guidance device such as radar or optics to guide the vehicle along a planned guidance path without the need for a separate bottom rail; the top of the cargo trolley can be provided with a platform for the cargo box and an electric take-up device that can be extended to the left and right The arm assembly and the electrically extended or retracted electric lifting seat can be used in conjunction with the upper and lower rails and the commercially available chains inside to perform lifting movements. Therefore, there is no need to lay a separate bottom rail, which can effectively reduce the width and weight of the loading trolley. In addition, the general commercially available chains can be quickly assembled for the loading trolley to perform lifting movements. The entire machine does not require hydraulic equipment and can be driven by electricity alone, which effectively reduces costs and is easy to assemble, integrate and maintain.
