Shunting device of rail stacker and shunting system with same and shunting method

Abstract

The invention relates to a shunting device of a rail stacker and a shunting system with same and a shunting method. The shunting device comprises a ground rail switching device, a sky rail switching device, a lower guide rail and an upper guide rail, wherein the lower guide rail and the upper guide rail are matched with the ground rail switching device and the sky rail switching device, respectively; the ground rail switching device and the sky rail switching device are vertically arranged symmetrically and synchronously rotate; the ground rail switching device comprises a lower round rotary table; the lower round rotary table comprises a stacker suitable for loading and a lower rotary plate which keeps relative static state rotation with the stacker, a lower rotary bracket arranged at the circle center of the lower rotary plate and a lower drive device driving the lower rotary plate to rotate; and a lower straight rail which is arranged along a diameter is arranged on the lower rotary plate; the sky rail switching device comprises an upper round rotary table; the upper round rotary table comprises an upper rotary plate, an upper rotary bracket arranged at the circle center of the upper rotary plate and an upper drive device driving the upper rotary plate to rotate; and an upper straight rail arranged along the diameter is arranged on the upper rotary plate; at a first position, the lower straight rail and the upper straight rail are respectively butt jointed with the ground rail and the sky rail which are arranged in a working roadway, and the lower straight rail and the upper straight rail are respectively butt jointed with the lower guide rail and the upper guide rail at a second position.

Description

technical field [0001] The invention relates to a stacking system, in particular to a stacking system with transferable rails. Background technique [0002] Rail stackers are widely used in automated three-dimensional warehouses, and are generally driven by the ground. Generally, two load-bearing wheels are used to run along the track laid on the ground, which is usually called ground rail operation. The lower two sets of horizontal wheels run along the track for guidance, and the two sets of guide wheels on the top of the stacker run along the upper track (usually also called sky rail) to assist in guiding. [0003] Normally, the rail stacker runs in a straight line in each lane, and when the rail stacker in one lane fails, the rail stacker in another lane needs to be able to run to the lane Come emergency. Or, when there are many lanes, the frequency of entering and leaving the warehouse is low, and the configuration of the rail stacker is limited, the rail stacker is a...

Problems solved by technology

However, in this switching system, after the stacker passes through the switching device from the roadway where it is located, it needs to run backwards to make it reach the target roadway and maintain the same front and rear direction as it was in the original roadway, which reduces work efficiency.

[0006] At the same time, in Chinese patents CN201105905Y and CN101481040, when the stacker shifts between the vertical roadways, it is a circular arc transfer. In order to avoid the interference between the stacker and the shelf, a larger space needs to be reserved for this transfer method. The area is large, and the stacker must have a vertical shaft on the upper part of the guide wheel because it needs to realize circular arc walking, so the structure is complicated
