Travelling control device and method of aisle stacker

Abstract

The invention discloses a travelling control device of an aisle stacker. The travelling control device of the aisle stacker comprises an aisle combined ground rail and a stacker body arranged on the aisle combined ground rail. A horizontal travelling mechanism is arranged between the stacker body and the aisle combined ground rail. The stacker body is further provided with a travelling communication positioning system based on a gray bus communication technology and a travelling control system used for controlling the horizontal travelling mechanism and the travelling communication positioningsystem. The upper surface, the front side face and the back side face of the aisle combined ground rail are all provided with travelling rails. A travelling control method of the aisle stacker comprises the following steps that S100, based on different operation modes, the stacker body receives a control instruction, determines target operation and starts to work; S200, in the work process, real-time accurate positioning and speed control are conducted on the stacker body; and S300, after work is completed, the stacker body returns to the original position. By the adoption of the travelling control device and method of the aisle stacker, operation is easy and convenient, and the accurate positioning function on the aisle stacker can be achieved while the high-speed high-acceleration operation state is guaranteed.

Description

technical field [0001] The invention relates to the technical field of a roadway stacker, in particular to a walking control device and a control method of a roadway stacker. Background technique [0002] Roadway stacker is evolved from forklift and bridge stacker. Due to the heavy bridge frame, the running speed of bridge stacker is greatly limited. It is only suitable for infrequent storage and storage of long raw materials. And the warehouse of bulky goods, the main purpose of the roadway stacker is to shuttle back and forth in the roadway of the high-rise shelf, to store the goods at the entrance of the roadway into the cargo compartment; or to take out the goods in the cargo compartment and transport them to the entrance of the laneway, As the core logistics equipment of the automated three-dimensional warehouse, the stacker is not only the most widely used material handling equipment in the three-dimensional warehouse, but also the most important equipment in the logis...

[0002] Roadway stacker is evolved from forklift and bridge stacker. Due to the heavy bridge frame, the running speed of bridge stacker is greatly limited. It is only suitable for infrequent storage and storage of long raw materials. And the warehouse of bulky goods, the main purpose of the roadway stacker is to shuttle back and forth in the roadway of the high-rise shelf, to store the goods at the entrance of the roadway into the cargo compartment; or to take out the goods in the cargo compartment and transport them to the entrance of the laneway, As the core logistics equipment of the automated three-dimensional warehouse, the stacker is not only the most widely used material handling equipment in the three-dimensional warehouse, but also the most important equipment in the logistics storage system. With the expansion of the scale of the automated three-dimensional warehouse and the rapid response to customer requirements , the stacker needs to complete tasks such as warehousing, picking, outbound, and distribution in a very short period of time. Poor, low work efficiency, and high labor costs. During the manual operation of the roadway stacker, the transported goods may fall and hurt the operator, and the safety performance is not high. Therefore, the automatic stacker The appearance of the automatic stacker has become a trend, but the function of the existing automatic stacker is relatively single, and the automated workflow will not work once a fault occurs, and maintenance is troublesome; moreover, during the working process of the automated stacker, the stacker The walking speed is often fixed, and can only complete the operation of starting, emergency stop and running at a certain speed. If the speed is too small, the working efficiency of the stacker will be reduced; if the speed is too high, collision accidents will easily occur, and due to inertia, Make the position accuracy of the stacker low, thus making its work quality worse

[0003] Just as the application number is 201310435614.8, which is an invention of an intelligent control method for an automated three-dimensional warehouse. In this invention, a horizontal direction address device that moves back and forth with the stacker is installed on the bottom beam of the stacker, and its corresponding address sheet Corresponding to the ground position of each row of warehouses, each time a row of warehouses passes, the horizontal direction addresser sends a pulse signal to the PLC through the addressing baffle to achieve the purpose of column addressing, thereby realizing the automatic operation of the stacker's horizontal walking , speed up the working efficiency of the stacker, but, for other problems raised above, this invention does not solve
