Description

Technical Field

[0001] The patent of this invention relates to the technical field of dense storage four-way shuttle racks in the logistics and warehousing industry, specifically a four-way shuttle reversing track. Background Art

[0002] With the rapid development of the logistics industry, various types of high-density storage automated stereoscopic warehouse shelves are constantly emerging. The four-way shuttle shelf is one of the multi-layer, high-density storage shelves. Each layer of the four-way shuttle shelf is densely covered with many X-direction and Y-direction vertically intersecting walking channels. The four-way shuttle logistics robot can walk and carry goods along these X-direction and Y-direction vertically intersecting walking channels; the Y-direction walking channel is the main walking channel for the logistics robot on the four-way shuttle shelf. The walking track in the Y-direction walking channel is mainly composed of the Y-direction track and the reversing track. The X-direction walking channel is the sub-channel for the logistics robot on the four-way shuttle shelf to walk. The walking track in the X-direction walking channel is mainly composed of the X-direction track; the reversing track is installed at each vertical intersection of the X-direction and Y-direction tracks. It connects the X-direction and Y-direction tracks and is an important part of the walking track of the four-way shuttle shelf. The four-way shuttle logistics robot can realize reversing walking at the vertical intersection of the X-direction and Y-direction tracks through the reversing track.

[0003] The surface of the existing four-way shuttle reversing track needs to be galvanized after welding because it has to bear the positive pressure of the wheels of the four-way shuttle logistics robot, which leads to excessively high production costs. The existing rectangular tubes are connected by welding, which will seriously shorten their service life during long-term rolling. Therefore, a four-way shuttle reversing track is urgently needed to improve the above problems.

[0012] By adopting the above technical solution, the rectangular tube is replaced and the hot-dip galvanizing process is cancelled, thereby reducing the production cost.

[0013] The patent of the present invention is further configured as follows: through holes are processed on both the first bending ear plate and the second bending ear plate, and the through holes processed on the first bending ear plate are fixing holes for fixing the reversing rail to the shelf with bolts.

[0014] By adopting the above technical solution, through holes are processed on the first bending ear plate and the second bending ear plate, which facilitates the use of bolts for fixing.

[0015] The patent of the present invention is further configured as follows: the bending angles of the first bending ear plate and the second bending ear plate are the same, the first bending ear plate and the second bending ear plate are integrated with the replacement rectangular tube, and the notch is opened at the top of the replacement rectangular tube.

[0017] The patent of the present invention is further configured as follows: the size and position of the notch are the same as the spacing of the Y-direction track and the cross-sectional size of the Y-direction track of the four-way shuttle robot.

[0018] By adopting the above technical solution, the spacing of the Y-direction track of the four-directional shuttle robot is the same as the cross-sectional size of the Y-direction track, which facilitates the passage of the four-directional shuttle robot.

[0019] The patent of the present invention is further configured as follows: the first bending ear plate, the second bending ear plate and the notch are all manufactured by a single replacement rectangular tube using laser cutting and bending processes, and the replacement rectangular tube has toughness.

According to sampling statistics of different project plans, the production cost of the four-way shuttle reversing track accounts for about 8%-10% of the total cost of the four-way shuttle rack. One of the main reasons for the high proportion of the production cost of the reversing track is that the hot-dip galvanizing process cost of the reversing track is high, and the hot-dip galvanizing process cost accounts for about 30% of the total production cost of the reversing track. Therefore, the present invention cancels the hot-dip galvanizing process in the production process of the reversing track, which can effectively reduce the total production cost.

In this embodiment, the two end remaining track tube bodies 3 support the first bending ear plate 4 and the second bending ear plate 5, and the middle remaining track tube body 2 plays a guiding role.

[0033] Reference Figure 2 and Figure 3 It is an existing structure. The existing rectangular tube 7 includes an intermediate upper track tube 8. A lower rectangular tube 13 is arranged at the bottom of the intermediate upper track tube 8. End connecting plates 9 are arranged on both sides of the intermediate upper track tube 8. Upper track tubes 10 at both ends are arranged on one side of the end connecting plates 9. Track fixing seats 11 are arranged on one side of the upper track tubes 10 at both ends. In this embodiment, the lower rectangular tube 13 plays a role in fixing the existing rectangular tube 7, and the upper track tubes at both ends play a role in facilitating the welding of the fixing seats 11.

[0034] Reference Figure 1 and Figure 2 The model and specification of the replacement rectangular tube 1 can be selected according to actual needs. In the embodiment of the present invention, the replacement rectangular tube 1 is a galvanized carbon steel rectangular tube. In this embodiment, the replacement rectangular tube 1 serves to replace the existing rectangular tube 7, thereby extending the service life of the entire mechanism.

[0035] Reference Figure 2The existing rectangular tube 7 is a carbon steel rectangular tube with galvanized surface. The replacement rectangular tube 1 cancels the hot-dip galvanizing process. The surface of the existing pipe 7 is provided with galvanizing. The existing rectangular tube 7 is fixedly connected to the top of the lower rectangular tube 13. The fixing seat 11 is welded to the top of the lower rectangular tube 13. In this embodiment, the galvanized carbon steel rectangular tube is the material for replacing the rectangular tube 1 and the existing rectangular tube 7, and the hot-dip galvanizing process plays a role in covering the welding point.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The first bent ear plate 4 and the second bent ear plate 5 are both processed with through holes 12. The through holes 12 processed on the first bent ear plate 4 are fixing holes for fixing the reversing track to the shelf with bolts. In this embodiment, the first bent ear plate 4 serves to replace the end connecting plate 9 and serves as the end connecting plate 9 to fix the reversing track to the shelf with bolts.

[0037] Reference Figure 1 The first bending ear plate 4 and the second bending ear plate 5 have the same bending angle, the first bending ear plate 4 and the second bending ear plate 5 are integrated with the replacement rectangular tube 1, and the notch 6 is opened at the top of the replacement rectangular tube 1. In this embodiment, the first bending ear plate 4 and the second bending ear plate 5 both play a role of limiting, and the notch 6 plays a role in preventing the four-way shuttle logistics robot from being scratched.

[0038] Reference Figure 1 The size and position of the notch 6 are the same as the spacing of the Y-direction track and the cross-sectional size of the Y-direction track of the four-way shuttle robot. In this embodiment, the notch 6 serves as a reserved space to facilitate the movement of the four-way shuttle robot.

[0039] Reference Figure 1 , Figure 2 and Figure 3 The first bent ear plate 4, the second bent ear plate 5 and the notch 6 are all made of a single replacement rectangular tube 1 using laser cutting and bending processes. The replacement rectangular tube 1 has toughness. In this embodiment, the second bent ear plate 5 replaces the gap between the upper track tubes 10 at both ends and the middle upper track tube 8 to leave space for the Y-direction track to pass through here.

[0040] The implementation principle of this embodiment is:

[0041] In the embodiment of the present invention, a single surface is replaced by a galvanized rectangular tube, and laser cutting is used to cut out a first bending ear plate 4 and a second bending ear plate 5. The bending process is used to design and manufacture the first bending ear plate 4 and the second bending ear plate 5, so that the first bending ear plate 4 and the second bending ear plate 5 are bent outward at the same angle, and no welding is required, and no galvanizing is required after welding. In terms of function and performance, it can well replace the existing reversing track that is made by welding multiple parts together and then galvanizing. The embodiment of the present invention can significantly reduce the production cost of the four-way shuttle reversing track, and also significantly improve the production efficiency, and incidentally reduce the pollution caused by the production process to the environment, making the production process more environmentally friendly. The first bending ear plate 4 and the second bending ear plate 5 are used in combination to replace the end connecting plate 9 and the fixing seat.

[0042] Compared with the prior art, the present invention has the following beneficial effects:

[0043] By providing the notch 6, a limiting function is achieved; by cooperating with the first bent ear plate 4 and the second bent ear plate 5, a fitting function is achieved; by providing the through hole 12, it is convenient to use bolts for fixing; by adopting laser cutting and bending, the first bent ear plate 4 and the second bent ear plate 5 are integrally formed, which can effectively improve their durability. According to sampling statistics of different project plans, the production cost of the reversing track accounts for approximately 8%-10% of the total cost of the four-way shuttle rack. One of the main reasons for the high proportion of the production cost of the reversing track is that the hot-dip galvanizing process cost of the reversing track is relatively high, and the hot-dip galvanizing process cost accounts for approximately 30% of the total production cost of the reversing track. Therefore, the present invention cancels the hot-dip galvanizing process in the production process of the reversing track, which can effectively reduce the total production cost.

[0044] The embodiments of this specific implementation method are all preferred embodiments of the patent of the present invention, and are not intended to limit the protection scope of the patent of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the patent of the present invention should be covered within the protection scope of the patent of the present invention.
