Description

Technical Field

[0001] This utility model relates to the technical field of stopper structures for automated warehouse shuttle systems, specifically to a stopper and an automated warehouse shuttle system. Background Technology

[0002] In the automated storage and retrieval system (AS / RS) shuttle car system, shuttle cars switch to different storage layers via a hoist. Before entering the hoist, a shuttle car track stopper is often used at the end of the track. The shuttle car track stopper has two working states: blocking and non-blocking. To prevent transport vehicles or other transport devices in the track from moving outside the track, the end of the track is used to connect with the track on the hoist tray, allowing the shuttle car to drive from the AS / RS track into the hoist track. The stopper mechanism is mainly used to protect the shuttle and prevent it from running out of control and crashing off the track. When the hoist reaches the height of the shuttle car, the hoist provides thrust, and the stopper flips open. After flipping, it is on the same plane as the track, allowing the shuttle car to pass through and enter the hoist.

[0003] Existing barriers use a purely mechanical structure and are bolt-fixed, making their use and disassembly cumbersome and inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide a barrier and a vertical warehouse shuttle system to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A stopper includes a base, the base having a notch in the direction of impact by a shuttle, a rotatable stop block being disposed within the notch, and a push rod mechanism being disposed on the base in the direction of the elevator.

[0007] The blocking block includes a body and a spring. The horizontal movement of the push rod mechanism under the action of force is converted into the rotational movement of the spring. The spring drives the body to flip under the action of rotational movement. When the body flips above the gap, it blocks the shuttle. When the body flips below or level with the gap, it loses its ability to block the shuttle.

[0008] Furthermore, the notch of this utility model is provided with an inclined surface facing the base. The tip of the inclined surface is used for auxiliary vertical positioning of the blocking block. At the same time, when the blocking block is impacted, the inclined surface acts as a backrest support to prevent the blocking block from exceeding the vertical angle when the blocking device is subjected to a strong impact, thus preventing it from being difficult to reset.

[0009] Furthermore, the blocking block body of this utility model has a slot inside, and a spring is installed inside the slot; a gear shaft passes through the base, one end of the gear shaft passes through the blocking block body, and the gear shaft located inside the blocking block body is provided with a mounting hole that matches the spring; the gear shaft and the spring are fixed in the blocking block body by pan head screws.

[0010] Furthermore, this invention features a base that matches the body of the blocking block, equipped with an elastic screw. The notch end of the base is fitted with the elastic screw to provide a rebound force when the blocking block resets. After the blocker flips, because the tension provided by the spring and the blocking block are on the same plane, there is a possibility that it may occasionally fail to spring back to its original position. The elastic screw effectively solves this problem, providing an upward rebound force to the blocking block. When the blocking block and the spring tension form a slight angle, it can easily reset, thereby improving the efficiency of the blocker and enabling it to operate effectively.

[0011] Furthermore, a second spring washer and a flat washer are fitted onto the pan head screw of this utility model.

[0012] Furthermore, the push rod mechanism of this utility model includes a circular rack that passes through the base and is perpendicular to the length direction of the gear shaft, with one end of the circular rack engaging with a gear on the gear shaft; a spring is arranged on the outer circumference of the circular rack near the gear shaft. When an external force pushes the circular rack to run, the spring is compressed, and the rack at the front end of the circular rack drives the gear shaft to rotate; the blocking block and the gear shaft are linked by a spring plate, that is, when the gear shaft rotates, the blocking block is driven to rotate through the spring plate.

[0013] Furthermore, a copper sleeve is provided at the end of the circular rack near the gear shaft. The copper sleeve at the point where the circular rack and the base move relative to each other serves to prevent wear.

[0014] Furthermore, a second plug is provided on the base that matches the copper sleeve in this utility model.

[0015] Furthermore, the present invention features a waist-shaped groove at the end of the rack away from the gear shaft, and a cylindrical head screw extending into the waist-shaped groove is provided on the base. After the shuttle car passes, the external force is removed, the spring resets, and the rack returns to a vertical state via the gear linkage blocking block. The waist-shaped groove serves to limit the movement of the rack.

[0016] Furthermore, this invention includes a first plug on the base located on the gear side near the gear shaft. A retaining ring is provided on the base located on the gear side away from the gear shaft. This facilitates adjustment of the gear shaft's position.

[0017] A vertical warehouse shuttle system includes the barrier of this invention, which is arranged on a track for shuttle passage.

[0018] Furthermore, this invention includes a stopper on each track. Countersunk screws are used to install and secure the stopper mechanism to the track. The number of countersunk screws is at least four. They are evenly distributed to ensure balanced force distribution.

[0019] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0020] 1. This utility model utilizes a vertically arranged gear shaft and a circular rack. When an external force pushes the circular rack to run, the spring is compressed, and the rack at the front end of the circular rack drives the gear shaft to rotate. The gear shaft, through a spring plate fixed to it, drives the blocking block to flip by 90°, changing the blocking block from a vertical state to a horizontal state and compressing the elastic screw. At this time, the blocking device is flush with the shuttle car track surface, allowing passage. After the shuttle car passes, the thrust is removed, the spring returns to its original position, and the blocking block returns to a vertical state through gear linkage. The blocking block and the gear shaft are linked by the spring plate, that is, when the gear shaft rotates, it drives the blocking block to rotate through the spring plate. Through the connection of the spring plate, the blocking device can be buffered to a certain extent, avoiding gear damage or deformation of the cylindrical head screw, thus extending the life of the blocking device.

[0021] 2. This utility model uses an elastic screw to provide a reverse rebound force when the blocking block is reset. After the blocker flips, because the tension provided by the spring and the blocking block are on the same plane, there is a possibility that it may occasionally fail to spring back to reset. The elastic screw effectively solves this problem and can provide an upward rebound force to the blocking block. When the blocking block and the spring tension form a slight angle, it can be easily reset, thereby improving the efficiency of the blocker and enabling the blocker to operate effectively.

[0022] 3. The base notch of this utility model adopts a beveled design, which can not only ensure the rotation of the blocking block, but also provide the functions of limiting and backrest support.

[0023] 4. The circular rack and the base of this utility model are equipped with copper sleeves at their internal moving parts, which play a role in preventing wear and extending the service life of the entire system. Attached Figure Description

[0033] The present invention will be further described in detail below with reference to the accompanying drawings:

[0034] like Figure 1 , Figure 2 , Figure 8 As shown, a blocker includes a base 4, the base 4 having a notch in the direction of impact by the shuttle car, a rotatable blocking block 1 being provided in the notch, and the base 4 also having a push rod mechanism in the direction of the elevator.

[0035] The blocking block 1 includes a body and a spring piece 2. The horizontal movement of the push rod mechanism under the action of force is converted into the rotational movement of the spring piece 2. Under the action of the rotational movement, the spring piece 2 drives the body to flip. When the body flips above the gap, it blocks the shuttle car. When the body flips below or level with the gap, it loses its ability to block the shuttle car.

[0036] like Figure 6 , Figure 7 As shown, the notch of this utility model is provided with an inclined surface facing the base 4.

[0037] like Figure 1 , Figure 4 As shown, the blocking block 1 of this utility model has a slot inside, and a spring piece 2 is installed inside the slot; a gear shaft 7 is inserted on the base 4, and one end of the gear shaft 7 is inserted on the body of the blocking block 1. The gear shaft 7 located inside the body of the blocking block 1 is provided with a mounting hole that matches the spring piece 2. The gear shaft 7 and the spring piece 2 are fixed in the body of the blocking block 1 by pan head screws 16.

[0038] like Figure 1 , Figure 3 , Figure 5As shown, an elastic screw 17 is provided on the base 4 that matches the body of the blocking block 1.

[0039] like Figure 1 As shown, a second spring washer 14 and a flat washer 15 are fitted onto the pan head screw 16 of this utility model to protect the outer peripheral surface of the blocking block 1.

[0040] like Figure 1 , Figure 4 As shown, the push rod mechanism of this utility model includes a circular rack 8 that passes through the base 4 and is perpendicular to the length direction of the gear shaft 7. One end of the circular rack 8 meshes with a gear on the gear shaft 7. A spring 9 is arranged on the circular rack 8 near the outer circumference of the gear shaft 7. Figure 4 The base 4 is provided with a protrusion for providing resistance to the spring 9, and the rack of the circular rack 8 is engaged with the gear of the wheel axle 7.

[0041] like Figure 1 , Figure 4 As shown, a copper sleeve 11 is provided on the end of the circular rack 8 near the gear shaft 7 of this utility model. A second plug 10 matching the copper sleeve 11 is provided on the base 4.

[0042] like Figure 1 , Figure 4 As shown, the end of the circular rack 8 away from the gear shaft 7 of this utility model is provided with a waist-shaped groove, and the base 4 is provided with a cylindrical head screw 13 extending into the waist-shaped groove. A first elastic washer 12 is arranged between the cylindrical head screw 13 and the base 4.

[0043] like Figure 1 As shown, a first hole plug 5 is provided on the base 4 on the gear side near the gear shaft 7. A retaining ring 3 is provided on the base 4 on the gear side away from the gear shaft 7.

[0044] like Figure 8 As shown, this utility model also provides a vertical warehouse shuttle system, including the barrier of this utility model, which is arranged on the track for shuttle passage. One barrier is set on each track. When the barrier is in a vertical state, it blocks the shuttle passage; when the barrier is subjected to a pushing force, it rotates 90 degrees from the vertical state and flips to a horizontal state, allowing the shuttle passage.

[0045] like Figure 1 As shown, the base 4 on the stopper of this utility model is connected to the track by a number of countersunk screws 6. The number of countersunk screws 6 is at least 4.

[0046] like Figure 1-8 As shown, this utility model provides a stopper and a vertical warehouse shuttle system. The base 4 has a set of mutually perpendicular through holes. Figure 1 , Figure 2Spring 9 and rack 8 are sequentially inserted into the through hole from the X-axis direction; rack 8 has a slotted groove at one end and a rack at the other end, see Figure 3 A copper sleeve 11 is installed at the internal moving part of the circular rack 8 and the base 4 to prevent wear; the first spring washer 12 and the cylindrical head screw 13 are installed in the base 4 and locked in the waist-shaped groove of the circular rack 8 to limit the circular rack 8.

[0047] The gear shaft 7 and the blocking block 1 are sequentially installed into the base from the Y-axis direction, with the blocking block 1 positioned at the notch in the base 4. An inclined surface is formed at the notch in the base 4, as shown in the image. Figure 7 The tip of the inclined surface is used for auxiliary vertical positioning of the blocking block 1. At the same time, when the blocking block 1 is impacted, the inclined surface acts as a backrest support to prevent the blocking block 1 from exceeding the vertical angle when the blocker is subjected to a strong impact, making it difficult to reset.

[0048] The spring clip 2 is inserted into the opening inside the gear shaft 7 through the slot of the blocking block 1 and is fixed by the pan head screw 16. An upward arrow is engraved on the gear shaft 7. Figure 4 Ensure that the blocking block 1 is in a vertical position after assembly.

[0049] The base 4 has a notch end fitted with a resilient screw 17 to provide a restoring force when the blocking block 1 is reset. The countersunk screw 6 is used for mounting and fixing the blocking mechanism to other related components, such as... Figure 4 As shown, the thrust applied by the motor drives the rack 8 to run, compressing the spring 9. The rack at the front end of the rack 8 drives the gear shaft 7 to rotate. The gear shaft 7, through the spring plate 2 fixed thereon, drives the blocking block 1 to flip by 90°, changing the blocking block 1 from a vertical state to a horizontal state (see...). Figure 6 (The blue section represents the passage state), and the elastic screw 17 is compressed. At this time, the stopper is flush with the shuttle car track surface, allowing passage. After the shuttle car passes, the thrust is released, the spring 9 resets, and the stopper block 1 returns to the vertical state via the gear linkage (see...). Figure 6 (The state of obstruction).

[0050] The blocking block 1 and the gear shaft 7 are linked by the spring plate 2. That is, when the gear shaft 7 rotates, the blocking block 1 is driven to rotate through the spring plate 2. The spring plate connection has the following advantages over the rigid connection: 1. The elastic connection has a certain buffering effect, avoiding damage to the gear or deformation of the cylindrical head screw 13 when impacted; 2. Avoiding overload damage to the motor that opens the blocking device.

[0051] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
