Description

[Technical Field]

[0001] The present invention relates to a technology for storing and managing goods in a warehouse, for example, and in particular to a smart rack that uses gravity and magnetic force to detect the entry and exit of goods and has adjustable shelf widths for storing goods. [Background technology]

[0002] Conventionally, when storing luggage on a shelf, a code is attached to the shelf, and the correspondence between the luggage to be stored and the shelf code is recorded and checked to store and manage the luggage on the shelf. However, with this method, for example, a worker can use the code attached to the shelf as a landmark to quickly identify the location of the desired shelf, which improves work efficiency to a certain extent, but since the worker must manually scan the shelf code and the code on the package, it takes time to search for the stored package, and work efficiency is low. Therefore, there is a conventional technology that installs a monitoring device that detects luggage on the shelves, eliminating the need to scan shelf codes when loading and unloading luggage, thereby further improving work efficiency and automatically detecting incorrect loading and unloading operations. For example, Patent Document 1 discloses a shelf load detection device comprising an incoming sensor that is installed on the loading platform of a crane on the incoming side and has a light emitter and receiver facing the shelf direction, an incoming detection means that is installed on the shelf and has a reflector that reflects towards the incoming sensor, and an outgoing sensor that is installed on the loading platform of a crane on the outgoing side and has a light emitter and receiver facing the shelf direction, and an outgoing detection means that is installed on the shelf and has a reflector that reflects towards the outgoing sensor. In this device, each reflector is arranged so that it can be moved between a retracted position where goods can pass over the reflector and a position where it can reflect the light emitted from the incoming sensor or outgoing sensor.When there is no goods on the shelf, the light emitted from the incoming sensor is reflected by the reflector installed on the shelf and received by the incoming sensor, so that the absence of goods can be detected reliably.

[0003] However, the shapes and sizes of luggage vary, and the width of the shelves required varies accordingly, from narrow to wide. Previous shelf codes, indicator lights, and sensing and monitoring devices were all designed based on a fixed shelf width, making it difficult to flexibly accommodate different sizes of cargo.

It is characterized by: [Effects of the Invention]

[0013] The simple structure of the system, in which a sensing mechanism is activated by the weight of the luggage and then automatically resets using magnetic force, allows it to detect the arrival and departure of luggage, providing excellent stability. The shelf width for storing luggage can be freely adjusted according to the size of the luggage, allowing for flexible handling of luggage of various sizes. By equipping each shelf with a sensor and LED indicator light, the status of goods being stored and retrieved can be automatically detected and displayed, greatly improving work efficiency and the accuracy of storage and retrieval management.

[0014] The width of the shelves is adjustable, and adjacent switching lever assemblies can be connected or disconnected by attaching or detaching shelf position connecting members. When loading or unloading luggage, if multiple adjacent switching lever assemblies are in a coupled state, they rotate simultaneously, and the multiple corresponding Hall sensors detect the contact or non-contact of the multiple simultaneously operating sensitive magnets and send an electrical signal to the microprocessor. When the coupling state is released, each switching lever assembly rotates independently, and the corresponding Hall sensor individually detects whether the sensitive magnet is in contact or not. This makes it possible to detect loading and unloading operations and manage storage flexibly, even for items of different widths.

[0015] When luggage is stored, the weight of the luggage causes the switching lever assembly to rotate, and the induction magnet moves away from the Hall sensor. At the same time, the return magnet on the switching lever assembly moves away from the iron wire installed in the front cross beam, switching the electrical signal in the Hall sensor, which sends the signal to the microprocessor, which determines that the luggage has been stored. When the luggage is removed, the weight of the luggage is removed, and the switching lever assembly rotates due to the magnetic force of the return magnet and returns to its original position. This causes the induction magnet to come into contact with the Hall sensor, switching the Hall sensor's electrical signal again, which is then sent to the microprocessor, which determines that the baggage has been removed.

[0016] In this way, the induction magnet and Hall sensor form a non-contact induction structure, which can prevent malfunctions caused by external factors such as dust, contact oxidation, and light interference. Furthermore, since the switching lever assembly is returned to its original position by magnetic force, there is no need to obtain a returning force using an elastically deformable member such as a spring or a leaf spring, which simplifies the structure and improves durability. The microprocessor receives changes in the electrical signal from the hall sensor and controls the on / off and color display of the LED lamp, allowing it to quickly notify workers of information necessary for their work, such as the status of items being brought in and out of storage.

[0018] Specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0019] As shown in Figures 1 to 10, the smart rack of this invention, which uses gravity and magnetic force to detect the loading and unloading of cargo and allows the width of the shelf position to be adjusted, is composed of a front cross beam assembly 1, a left support frame 2, a right support frame 3, a rear cross beam 4, a shelf position stopper 5, and a fixing screw 6.

[0020] The left support frame 2 and the right support frame 3 are attached to the front cross beam assembly 1 and the rear cross beam 4 via fixing screws 6, respectively. A plurality of stopper front end mounting holes 8 are formed at equal intervals on the top surface of the front end cross beam assembly 1. A plurality of stopper rear end mounting holes 7 are formed at equal intervals on the upper surface of the rear end cross beam 4. The shelf position stopper 5 is attached to the front end cross beam assembly 1 and the rear end cross beam 4 with the lower end of the shelf position stopper 5 inserted into the stopper rear end mounting hole 7 and the stopper front end mounting hole 8.

[0021] The front cross beam assembly 1 is composed of a front cross beam 9, a circuit board 10, screws 15, iron wire 19, a switching lever assembly 20, and a shelf position connecting member 22. The front cross beam 9 comprises a stud bolt 14, a switching lever mounting projection 16, a switching lever mounting hole 17, and a C-shaped iron wire mounting groove 18. The circuit board 10 is attached to the stud bolts 14 by screws 15 . The iron wire 19 is attached to the C-shaped iron wire attachment groove 18 . The switching lever assembly 20 has a switching lever rotation shaft 21, and the switching lever rotation shaft 21 is fitted into the switching lever attachment hole 17 so as to be freely rotatable.

[0022] The circuit board 10 is provided with a Hall sensor 11, an LED lamp 12, and a microprocessor 13. The Hall sensor 11 and the LED lamp 12 are configured as a pair and are electrically connected to the microprocessor 13 . The microprocessor 13 receives the electrical signal from the Hall sensor 11 and outputs the electrical signal to the LED lamp 12 .

[0023] The switching lever assembly 20 has a rear end coupling hole 24 and a front end coupling hole 26 formed therein. The shelf position connecting member 22 has a rear end connecting protrusion 23 and a front end connecting protrusion 25 formed on the lower surface thereof so as to correspond to the rear end connecting hole 24 and the front end connecting hole 26 . When adjacent switching lever assemblies 20 are coupled together, the rear end coupling protrusion 23 is inserted into the rear end coupling hole 24, and the front end coupling protrusion 25 is inserted into the front end coupling hole 26, respectively.

[0024] Furthermore, the switching lever assembly 20 is provided with a return magnet mounting hole 27 and a response magnet mounting hole 29 . A return magnet 28 is provided in the return magnet mounting hole 27, and a response magnet 30 is provided in the response magnet mounting hole 29, respectively.

[0025] By inserting two shelf position stoppers 5 into two adjacent front end mounting holes 8 and two adjacent rear end mounting holes 7, a standard shelf position that is the width between the adjacent shelf position stoppers 5 can be formed. Narrow-width luggage 31 that is narrower than the width of this standard shelf position can be stored.

[0026] In addition, by removing some of the shelf position stoppers 5 from the front cross beam assembly 1 and the rear cross beam 4 and attaching the shelf position connecting member 22 to the adjacent switching lever assembly 20, a wide shelf position can be formed by connecting multiple standard shelf positions. And, wide luggage 32 wider than the width of this wide shelf position can be stored.

[0027] When narrow-width luggage 31 is stored, the switching lever assembly 20 is rotated by the weight of the stored luggage, the return magnet 28 moves away from the iron wire 19, and the induction magnet 30 moves away from the Hall sensor 11. This switches the electrical signal of the hall sensor 11, which is then sent to the microprocessor 13, which determines that the luggage has been stored and turns the LED lamp 12 on or off. Conversely, when the baggage is removed, the weight of the baggage is removed, and the switching lever assembly 20 rotates due to the magnetic force of the return magnet 28 and returns to its original position (the position where it contacts the iron wire 19). This causes the sensitive magnet 30 to approach the Hall sensor 11, switching the electrical signal of the Hall sensor 11 and sending the signal to the microprocessor 13, which determines that the luggage has been removed and turns the LED lamp 12 on or off.

[0028] When storing wide luggage 32, a plurality of shelf position stoppers 5 are removed according to the width of the luggage. The shelf position connecting member 22 is attached so as to connect the adjacent switching lever assemblies 20 in the vacant stopper front end mounting holes 8 and the vacant stopper rear end mounting holes 7 . This causes multiple adjacent switching lever assemblies 20 to rotate in the same manner, causing the electrical signals of the multiple corresponding Hall sensors 11 to switch simultaneously, and electrical signals are simultaneously sent to the microprocessor 13, which then determines whether luggage has been stored or removed and turns on or off the multiple LED lamps 12.
