[0030] The embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are only for the purpose of illustrating and explaining the present utility model and are not intended to limit the present utility model.

[0031] The present utility model provides a shelf device with a fall prevention function. By providing an actuator and a stopper on the shelf track, the actuator drives the stopper to move between an extended position and a retracted position. In the extended position, the stopper prevents the handling device from passing through; in the retracted position, the stopper allows the handling device to pass through, thereby providing a simple, safe and reliable shelf fall prevention mechanism. The following will be described in detail with reference to the accompanying drawings.

[0032] Figure 1 A shelf device 10 according to an embodiment of the present utility model is shown. Figure 2 A schematic diagram of the fall prevention mechanism is shown. As Figure 1 shown, the shelf device 10 includes a shelf track 11 and a fall prevention mechanism 12. A handling device (not shown in the figure) can move along the direction of the shelf track 11. In addition, the shelf device 10 further includes a goods storage space (not shown in the figure). The handling device moves along the shelf track 11 to a designated goods storage space, takes out the goods or bins therein, or puts the goods or bins into the goods storage space.

[0033] As Figure 1 shown, the fall prevention mechanism 12 is provided on the shelf track 11. As Figure 2 shown, the fall prevention mechanism 12 includes an actuator 121 and a stopper 122. The actuator 121 is provided on the shelf track 11 and can be electrically driven. The actuator 121 is, for example, a motor. As Figure 1 and Figure 2As shown, the motor is installed on the shelf track 11 through the motor bracket Brac. According to an embodiment of the present invention, the anti-falling mechanism 12 can be installed through the runway-shaped hole on the shelf track 11, and the length of the hole is set to be relatively large, so that the installation position of the anti-falling mechanism 12 can be adjusted within a certain range.

[0034] The stopper 122 is arranged on the shelf track 11 and can be driven by the actuator 121 to move between the extended position and the retracted position (for example, move along the vertical direction). In the extended position, the stopper 122 extends outwards and protrudes from the surface of the shelf track 11, thereby preventing the handling device from passing through; in the retracted position, the stopper 122 retracts to be flush with the surface of the shelf track 11 or is located below the surface, thereby allowing the handling device to pass through. The situations when the stopper 122 is in the extended position and the retracted position will be described in detail below.

[0035] As Figure 2 shown, the stopper 122 is, for example, a pin shaft, which can move up and down along the Figure 2 vertical direction therein, and a corresponding transmission device can also be arranged between the motor and the pin shaft as required, so as to convert the motion form (such as rotation) output by the motor into the up and down motion of the pin shaft. When the pin shaft moves upwards, it is in the extended position; when the pin shaft moves downwards, it is in the retracted position.

[0036] According to an embodiment of the present disclosure, the motor is a rotary motor. Correspondingly, the transmission device includes a gear 123 arranged on the output shaft of the motor, and a rack 124 meshing with the gear is arranged on the pin shaft. The gear 123 meshes with the rack 124, so as to convert the rotary motion of the motor into the up and down motion of the rack 124 and the stopper 122. Specifically, the output shaft of the motor can rotate bidirectionally. When rotating in one direction, the gear 123 rotates along with the output shaft of the motor, thereby driving the rack 124 and the stopper 122 downwards and driving the stopper 122 back to its retracted position (as Figure 3B shown); when the output shaft of the motor rotates in the other direction, the gear 123 rotates along with the output shaft of the motor, thereby driving the rack 124 and the stopper 122 upwards and driving the stopper 122 back to its extended position (as Figure 3A shown).

[0037] According to an embodiment of the present invention, the transmission device further includes a flange (not shown in the figure), and the gear 123 is arranged on the output shaft of the motor through the flange.

[0038] In the above embodiments, the implementation form of the transmission device is illustrated by taking a gear and a rack as an example. The present invention is not limited thereto, and different types of transmission devices can be provided according to needs. For example, through a cam structure, the cam is installed on the output shaft of the motor, and the stopper 122 is lifted or lowered by the movement of the cam, so as to drive to the extended position or the retracted position respectively. All of these are within the protection scope of the present invention.

[0039] According to an embodiment of the present invention, as Figure 2 shown, the shelf device further includes a bearing block 125, and the pin shaft 122 is arranged in the bearing block 125 and is guided by the bearing block 125 to move between the extended position and the retracted position. As Figure 2 shown, the bearing block has a through hole, and the inner diameter of the through hole is substantially the same as the diameter of the pin shaft 122. The pin shaft 122 is arranged through the through hole, so as to define the movement direction of the pin shaft 122. In addition, the shelf device 10 may further include a support 126, and the bearing block 125 is fixedly connected to the shelf rail 11 through the support 126.

[0040] As Figure 3A and 3B shown, according to an embodiment of the present invention, the shelf device further includes a position sensor 127, and the position sensor 127 is coupled to the actuator 121. The position sensor 127 is configured to detect whether the stopper 122 is in the extended position or the retracted position. The position sensor 127 can be arranged, for example, on the motor bracket Brac and faces the lower end of the stopper 122. As Figure 3A and 3B shown, the lower end of the stopper 122 has a notch. Therefore, when the stopper 122 is in the extended position (such as the position shown in Figure 3A ), the position sensor 127 corresponds to the notch position; when the stopper 122 is in the retracted position (such as the position shown in Figure 3B ), the position sensor 127 faces other parts of the stopper 127. In this way, the position sensor 127 can detect the position where the stopper 122 is located. Specifically, the position sensor 127 can emit detection light, and the detection light is reflected by the stopper 122 and then returns to the position sensor. The position sensor can calculate the distance according to the flight time of the detection light. When the measured distance is small, it indicates that the stopper 122 moves downward and is in the retracted position; when the measured distance is large, it indicates that the stopper 122 moves upward and is in the extended position.

[0041] In addition, the present invention is not limited to providing a notch at the lower end of the stopper 122. It is also possible not to provide the notch shown in the figure at the lower end of the stopper 122, but to set the length of the lower end of the stopper such that: when the stopper 122 is in the extended position (such asFigure 3A at the position shown, the stopper 122 is out of the range of the position sensor; when the stopper 122 is in the retracted position (such as Figure 3B the position shown), the lower end of the position sensor 127 faces the stopper 127. All of these are within the protection scope of the present utility model.

[0042] In addition, according to an embodiment of the present utility model, the position sensor 127 can be coupled to the actuator 121, and the actuator 121 can control the movement of the stopper 122 according to the detection result of the position sensor 127. For example, when the position sensor 127 detects that the stopper 122 has reached the retracted position, the actuator 121 stops driving the stopper 122; when the position sensor 127 detects that the stopper 122 has reached the extended position, the actuator 121 stops driving the stopper 122.

[0043] According to an embodiment of the present utility model, the shelf device further includes a trigger mechanism, the trigger mechanism is coupled to the actuator, and when the trigger mechanism is triggered, the actuator drives the stopper to move to the retracted position or the extended position.

[0044] such as Figure 4 shown, according to an embodiment of the present utility model, the shelf device further includes a transfer track 13, the transfer track 13 is arranged beside the shelf track, so that the handling device VEH can enter or leave the shelf track 11 through the transfer track 13. The transfer track 13 can be a fixed track.

[0045] In an embodiment of the present utility model, the shelf device 10 can include multiple layers of shelf tracks, for example, including multiple layers of shelf tracks in the vertical direction, so as to improve the space utilization rate and increase the density of goods storage. Correspondingly, the anti-falling mechanism is arranged on each layer of shelf track.

[0046] According to an embodiment of the present utility model, the shelf device further includes a lifting device, the lifting device is configured to lift the handling device VEH to the height of the shelf track or lower it to the ground. According to an embodiment of the present utility model, the stopper 122 is in the extended position by default. When the lifting device lifts the handling device VEH to the height of the shelf track, the trigger mechanism of the (this layer) shelf track will be triggered, so that the actuator drives the stopper to move to the retracted position. For the case of multiple layers of shelf tracks, a trigger mechanism can be arranged on each layer of shelf track. When the lifting device lifts the handling device VEH to this layer of shelf track, the trigger mechanism of this layer is triggered, so that the actuator of this layer drives the stopper to move to the retracted position.

[0047] An embodiment of the present utility model provides a shelf anti-falling mechanism that is simple, reliable, and occupies a small space. Compared with the prior art, its electrical control system has lower requirements and is easy to maintain.

[0048] Finally, it should be noted that the above are only embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
