Description

Technical Field

[0001] This utility model relates to the field of warehousing equipment technology, specifically to a mobile shelving component and a warehouse. Background Technology

[0002] Compared to fixed shelving, mobile shelving has the advantage of higher space utilization, because fixed shelving requires aisles between adjacent rows of shelving, while mobile shelving only requires one aisle between multiple shelving units.

[0003] Early mobile shelving systems were manually controlled, moving along guide rails by hand cranks. With technological advancements, automatically controlled mobile shelving systems have emerged. Based on the number of guide rails, mobile shelving systems can be categorized as single-rail, double-rail, and trackless.

[0004] For example, Chinese invention patent CN120397541A discloses a movable shelf, including a ground rail, several connected shelf groups, several support beams, a drive motor, and connecting rods. The support beams are set on the ground rail through driving wheels and driven wheels. Each support beam is connected to a ground rail. The driving wheels on adjacent support beams are connected through connecting rods. The drive motor is connected to any support beam. The drive motor is connected to the driving wheel in the support beam to drive the support beam to move along the direction of the ground rail. Two adjacent support beams are connected below the shelf group, and the adjacent edges of adjacent shelf groups are located on the same support beam. Multiple shelf modules are arranged sequentially on the ground rail.

[0005] Existing shelves are generally quite tall, and when they move forward or backward or start and stop, they often have the risk of tilting forward or backward due to inertia. Existing mobile shelves do not effectively protect against tilting or tilting. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, the purpose of this utility model is to provide a mobile shelving component and a warehouse.

[0007] The technical solution provided by this utility model is as follows: In a first aspect, a mobile shelving assembly includes: A movable base, with a shelf mounted on its upper end; The guide rail is provided with a guide groove that extends along the length of the guide rail and has its opening facing upward. The movable base is equipped with guide wheels, which are adapted to guide grooves; The guide rail is located on one side of the movable base; It also includes a limiting strip, the length of which is parallel to the length of the guide rail, and the limiting strip and the guide rail are located on the same side of the movable base; The limiting strip is provided with a limiting groove, which extends along the length of the limiting strip and the opening of the limiting groove faces the movable base. The opening of the guide groove is roughly perpendicular to the opening of the limiting groove; The mobile base is equipped with at least two limiting posts, which are located at the front and rear ends of the mobile base, and the limiting posts are adapted to the limiting grooves.

[0008] The movable base has guide rails and limiting strips on only one side to meet cost control and space-saving requirements. Guide wheels are fitted into guide grooves, and limiting posts are fitted into limiting grooves. The openings of the limiting grooves are approximately perpendicular to the openings of the guide grooves. There are two limiting posts, located at the front and rear ends of the movable base. This design prevents the movable base from shifting in a plane parallel to the ground and from tilting or tilting at the front and rear ends in the direction of travel.

[0009] As an optional technical solution in the first aspect, it also includes a magnetic track, the length direction of which is parallel to the length direction of the limiting strip and the guide rail; at least two magnetic sensors are installed on the movable base, the magnetic sensors are located at the front and rear ends of the movable base respectively, and the magnetic sensors correspond to the magnetic track.

[0010] By setting up a magnetic track and magnetic sensors, under normal circumstances, both magnetic sensors can detect signals. When one of them fails to detect a signal, it indicates that one end of the moving base is tilted, posing a risk of tilting.

[0011] Optionally, the magnetic track, limiting strip, and guide rail are arranged sequentially in the left-right direction, with the guide rail located on the side of the limiting strip away from the movable base. In this technical solution, the guide rail is on the outer side of the movable shelf, while the magnetic track is on the inner side. The inner magnetic track reduces the risk of being stepped on and lowers the probability of damage.

[0012] Furthermore, a pair of driving wheels and a pair of driven wheels are respectively installed on the left and right sides of the movable base; the movement path of the driving wheel and the driven wheel on one side is located between the magnetic track and the limiting bar. In this design, the limiting post and the magnetic sensor are located on both sides of the movement path of the driving wheel and the driven wheel, respectively, which avoids interference between the components and facilitates assembly.

[0013] Optionally, a motor is installed on the other side of the movable base. This motor drives the drive wheels on both sides of the movable base to rotate synchronously via a transmission mechanism. The motor can be electrically connected to a controller, which can be electrically connected to various sensors. Based on the signals detected by each sensor, the controller can control the motor to start and stop.

[0014] As an optional technical solution in the first aspect, a position sensor is installed on the movable base; at least two detection blocks are installed at intervals on the guide rail or limiting bar. The installation positions of the two detection blocks are determined according to the movable range of the movable base. When the position sensor detects a detection block, it proves that the movable base has moved to the limited position, at which point the movable base needs to stop moving, thereby preventing the movable base from moving beyond the limit.

[0015] As an optional technical solution in the first aspect, a first person sensor is installed at both the front and rear ends of the mobile base. This first person sensor is used to detect whether there is a person obstructing the front / rear side of the mobile base. When the first person sensor detects a person, if the mobile base is moving at that time, the motor is controlled to stop. If the mobile base is stopped at that time, it cannot be started even if a start signal is received, thus protecting personnel safety.

[0016] Furthermore, a second person sensor is installed on the shelf to detect whether there are people obstructing the view from the front or back of the shelf; the height of the second person sensor from the ground ranges from 1m to 2m. Installing a person sensor on the shelf expands the detection range and protects personnel safety.

[0017] As an optional technical solution in the first aspect, the movable base has multiple units; a distance detection sensor is installed on the shelf, which is used to detect the distance between shelves installed on adjacent movable bases. When multiple movable bases are placed along the length of the guide rail, it is necessary to avoid collisions between adjacent movable bases and shelves. The distance detection sensor is used to detect the distance between two adjacent movable bases and shelves. If two movable bases and shelves approach a set safe distance, the motor should decelerate or stop to prevent collisions between the movable bases and shelves.

[0018] Secondly, a warehouse includes the mobile shelving assembly described in the first aspect or any of the optional technical solutions in the first aspect. This warehouse uses only one guide rail to prevent the mobile base from shifting during movement. Furthermore, limit strips are provided to prevent the mobile base from tilting or tilting during single-rail guidance. In addition, multiple sensors are installed to prevent the mobile base and shelving from tilting, tilting, or colliding. Attached Figure Description

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0022] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0023] Specifically, in one embodiment, according to Figures 1-5 As shown, this application proposes a mobile shelving assembly, which includes a mobile shelving unit and a track mechanism. The track mechanism is used to guide the mobile shelving unit and to prevent the mobile shelving unit from tilting or leaning.

[0024] like Figure 1 , Figure 2 As shown, the mobile shelf includes a mobile base 1 and a shelf 2. The shelf 2 is installed on the upper part of the mobile base 1 and has multiple support rods to support materials. The shelf 2 is not limited to having support rods; it can also have multiple trays to support materials. The connection method between the shelf 2 and the mobile base 1, and the means by which the shelf 2 supports materials, are not the focus of this application and will not be elaborated upon here.

[0025] The track mechanism includes a guide rail 4 and a limiting strip 5. Both the guide rail 4 and the limiting strip 5 are fixed. In this embodiment, a single-rail guide is provided, so the track mechanism is only installed on one side of the movable base 1. Figures 1-5 The central track mechanism is located on the right side of the movable base 1. It should be noted that the track mechanism can also be located on the left side of the movable base 1.

[0026] The mobile shelf can move along the length of guide rail 4. For example... Figures 1-3 As shown, the direction in which the mobile shelving moves along guide rail 4 is defined as the front-back direction, that is, the length direction of guide rail 4 is the front-back direction. The direction that is in the same horizontal plane as the front-back direction and perpendicular to it is the left-right direction. The direction that is in the same vertical plane as the front-back direction and perpendicular to it is the up-down direction.

[0027] The guide rail 4 is provided with a guide groove 401, which extends along the length of the guide rail 4 and has its opening facing upward. A guide wheel 101 is installed on the movable base 1. The guide wheel 101 is adapted to the guide groove 401 and can be inserted into the guide groove 401. When the movable base 1 moves along the length of the guide rail 4, that is, when the movable shelf moves in the back-and-forth direction, the guide wheel 101 can roll along the guide groove 401.

[0028] It should be noted that at least two guide wheels 101 are provided, and the two guide wheels 101 are arranged at intervals in the front-back direction, so that the guide groove 401 can provide guidance and limit function, that is, to prevent the moving shelf from deviating in the horizontal plane composed of the front-back direction and the left-right direction during the movement.

[0029] The length direction of the limiting strip 5 is parallel to the length direction of the guide rail 4, that is, the limiting strip 5 and the guide rail 4 are arranged side by side. It should be noted that the limiting strip 5 and the guide rail 4 are located on the same side of the movable base 4 (shown as the right side in the figure).

[0030] The limit bar 5 is designed to prevent the mobile shelf from shifting in the vertical plane formed by the front-back and up-down directions, meaning the mobile shelf cannot tilt or lean.

[0031] Specifically, such as Figure 1 , Figure 3 , Figure 5 As shown, the limiting strip 5 is provided with a limiting groove 501, which extends along the length of the limiting strip 5 and is parallel to the guide groove 401. The opening of the limiting groove 501 faces the movable base 1, that is, the limiting groove 501 opens to the left or right (shown in the figure as opening to the left).

[0032] At least two limiting posts 102 are installed on the mobile base 1, for example, two posts. The two limiting posts 102 need to be arranged at intervals in the front-to-back direction. Preferably, the limiting posts 102 are located at the front and rear ends of the mobile base 1, and the limiting posts 102 are adapted to the limiting grooves 501. When the mobile shelf moves in the front-to-back direction, the limiting posts 102 can slide within the limiting grooves 501.

[0033] Preferably, the opening of the guide groove 401 is approximately perpendicular to the opening of the limiting groove 501. In the horizontal plane formed by the front-back direction and the left-right direction, and in the vertical plane formed by the front-back direction and the up-down direction, the moving shelf is constrained, restricted, and guided. When the shelf moves forward or backward or starts or stops, there is no risk of it tilting forward, backward, or shifting left or right due to inertia.

[0034] As an optional embodiment, the track mechanism also includes a magnetic track 6, the length direction of which is parallel to the length direction of the limiting strip 5 and the length direction of the guide rail 4, that is, the length direction of the magnetic track 6 extends in the front-back direction.

[0035] At least two magnetic sensors 7, preferably two, are installed on the movable base 1. The two magnetic sensors 7 are installed at intervals along the front-to-back direction on the movable base 1. Preferably, the two magnetic sensors 7 are installed at the front and rear ends of the movable base 1, respectively. In this case, if either end of the movable base 1 tilts or leans, the magnetic sensors 7 can detect it. Specifically, the magnetic sensors 7 correspond to the magnetic tracks 6. During installation, the magnetic sensors 7 should be able to detect the magnetic tracks 6. When one of the magnetic sensors 7 fails to detect the magnetic tracks 6, it indicates that the movable shelf has tilted or leaned during movement.

[0036] Optionally, the magnetic track 6, the limiting strip 5, and the guide rail 4 are arranged in sequence along the left and right direction, and the guide rail 4 is located on the side of the limiting strip 5 away from the movable base 1. In this case, the guide rail 4 is located on the outside and the magnetic track 6 is located on the inside. Setting the magnetic track 6 on the innermost side can reduce the risk of damage to the magnetic track 6 due to being stepped on or other situations.

[0037] Optionally, for the driving method of the movable base 1, a pair of driving wheels and driven wheels are respectively provided on the left and right sides of the movable base 1. The moving path of the driving wheel and driven wheel on one side is located between the magnetic track 6 and the limiting bar 5. At this time, the magnetic sensor 7 and the limiting post 102 are located on the left and right sides of the driving wheel and driven wheel, respectively.

[0038] A motor 3 is mounted on the other side of the movable base 1. This motor 3 drives the drive wheels on both sides of the movable base 1 to rotate synchronously via a transmission mechanism. For example, the motor 3 drives the transmission shaft 103 to rotate, and the transmission shaft 103 simultaneously drives the gear sets on both sides to rotate, thereby driving the drive wheels on both sides to rotate synchronously. The above-mentioned transmission mechanism is relatively mature in the prior art and will not be described or limited here.

[0039] As an optional implementation, the controller 13 can be electrically connected to the magnetic sensor 7 and the motor 3 respectively. Under normal circumstances, both magnetic sensors 7 can detect signals. When one of them fails to detect a signal, it indicates that one end is tilting and there is a risk of tilting. The controller 13 should control the motor 3 to stop driving the drive wheel to rotate and issue an alarm to remind personnel to stay away.

[0040] To further enhance safety performance, multiple sets of sensors can be installed, specifically: In one embodiment, a position sensor 8 is mounted on the movable base 1, and the position sensor 8 is electrically connected to the controller. At least two detection blocks 9 are installed at intervals on the guide rail 4 or the limit bar 5. Preferably, there are two detection blocks 9, which are located at the front and rear ends of the guide rail 4 or the limit bar 5. When the position sensor 8 detects the detection blocks 9 at both ends of the rail, it indicates that the shelf has moved to the end of the rail. At this time, the controller 13 should control the motor 3 to stop driving the drive wheel to rotate, and the shelf should stop moving.

[0041] In another embodiment, a first person sensor 10 is installed at both the front and rear ends of the mobile base 1. This first person sensor 10 is used to detect whether there is a person obstructing the front / rear side of the mobile base 1. The first person sensor 10 can be electrically connected to the controller 13. When the first person sensor 10 detects a person, if the mobile base 1 is moving at that time, the control motor 3 stops running. If the mobile base 1 is stopped at that time, the motor 3 cannot start even if it receives a start signal, thus protecting personnel safety.

[0042] In another embodiment, a second person sensor 11 is installed on the shelf 2. This second person sensor 11 is used to detect whether there is a person obstructing the front / back of the shelf 2. The second person sensor 11 can be electrically connected to the controller 13. When the second person sensor 11 detects a person, if the movable base 1 is moving at that time, the control motor 3 stops running. If the movable base 1 is stopped at that time, the motor 3 cannot start even if it receives a start signal, so as to protect the safety of personnel.

[0043] Preferably, the height of the second person sensor 11 above the ground is in the range of 1m to 2m. At this height, the detection range of the second person sensor 11 is relatively wide.

[0044] In another embodiment, multiple movable bases 1 are provided. In this case, a distance detection sensor 12 is installed on each shelf 2. This distance detection sensor 12 is used to detect the distance between shelves 2 installed on adjacent movable bases 1. The distance detection sensor 12 can be electrically connected to a controller 13. If two adjacent movable shelves approach a set safe distance, the motor 3 should decelerate or stop to prevent collisions between the movable shelves.

[0045] In one embodiment, this application also proposes a warehouse including the mobile shelving assembly described in any of the foregoing embodiments.

[0046] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
