[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0038] Figure 1is a structural block diagram of the multi-layer shelf system in the embodiment, refer to Figure 1 , a multi-layer shelf system, characterized in that it comprises: a shelf 100, a depositing device 200, a taking-out device 300, and a control device 400;

[0039] The shelf 100 includes multiple layers of storage channels, each layer of storage channels is inclined from a first side to a second side, and the height of the first side is higher than the height of the second side;

[0040] A first blocker and a second blocker are provided on the second side of each layer of the storage passage, wherein the first blocker is used to allow or prevent an object to be stored at the delivery position from entering the retrieval device, and the second blocker is used to allow or prevent an object from entering the delivery position;

[0041] The control device 400 is connected to the depositing device 200 and the taking-out device 300, and is used to control the depositing device to deposit the items to be stored into the designated storage channel, and control the taking-out device to take the items out of the designated storage channel;

[0042] The first side is the position of the storage channel close to the depositing device, and the second side is the position of the storage channel close to the taking-out device.

[0043] Exemplarily, in this solution, the shelf 100 is provided with multiple layers of storage channels, wherein the multiple layers of storage channels are arranged in sequence from bottom to top in the vertical direction, each layer of storage channels is used for storing items to be stored, and multiple items to be stored can be stored in one layer of storage channels;

[0044] In this solution, the storage channel is tilted, and it is set that the items are put in from the first side of the storage channel and taken out from the second side. When the items to be stored enter the storage channel, based on the slope of the storage channel and the weight of the items to be stored, the items slide from the first side to the second side.

[0045] The first object stored in the storage channel is limited by the first blocker to prevent it from sliding out of the storage channel, and the subsequent objects stored are limited by the previous object.

[0046] Exemplarily, in this solution, the control device 400 can be configured as a warehouse control system (Warehouse Control System, WCS), and the depositing device 200 and the taking-out device 300 can be stackers, conveyors, sorters, automated guided vehicles (Automated Guided Vehicle, AGV), etc.;

[0047] The configuration control device 400 is connected to the deposit device 200 and the withdrawal device 300 for communication, thereby achieving precise control and coordinated operation of the deposit device 200 and the withdrawal device 300;

[0048] In this solution, the control device 400 can be configured to receive warehouse operation tasks from the WMS (Warehouse Management System), such as warehousing, outbound, etc., and reasonably schedule the equipment to perform the tasks according to the priority of the task, the availability of the equipment (the depositing device 200 and the taking-out device 300) and the operation process, and monitor the progress of the task execution in real time, track and manage the tasks, and make timely adjustments and processing when abnormal situations occur in the tasks to ensure that the tasks are completed on time;

[0049] The operation data of the equipment (depositing device 200 and retrieving device 300) are collected in real time, such as the equipment position, speed, status, etc. By analyzing these data, the operation status of the equipment (depositing device 200 and retrieving device 300) can be understood, and equipment failures and abnormal conditions can be discovered in time.

[0050] Exemplarily, in this solution, the first blocker and the second blocker are used to realize the positioning and sorting of the items to be stored, and by controlling the action of the blocker, an item to be stored located on the second side is located at the shipping position to facilitate the subsequent taking-out operation;

[0051] In this solution, the storage passage between the first blocker and the second blocker is set to form a delivery position, and by setting the positions of the first blocker and the second blocker, the delivery position can accommodate exactly one item to be stored;

[0052] In this solution, the first blocker and the second blocker can be mechanical blockers, which can be composed of a blocking rod, a driving mechanism, and a mounting bracket, etc. The blocking rod can be extended or retracted by mechanical means to block or release the items to be stored, wherein the first blocker and the second blocker can be driven by pneumatic, hydraulic or electric means;

[0053] The first blocker and the second blocker may also be electromagnetic blockers, which are mainly composed of an electromagnet, a controller, and a mounting bracket. The electromagnetic blocker controls the extension and retraction of a blocking rod by turning the electromagnet on and off to block or release the items to be stored.

[0054] Exemplarily, in this solution, the types of objects to be stored may be the same or different, the sizes of the same types of objects to be stored may be the same, and the sizes of different types of objects to be stored may be the same or similar.

[0055] Exemplarily, in this solution, the working process of the multi-layer shelf system can be:

[0056] The control device 400 controls the designated depositing device 200 to transport the items to be stored to the designated shelf according to the established depositing task, and moves the items to be stored to the storage channel of the designated layer of the shelf. After the items to be stored enter the storage channel, they automatically slide into the storage channel based on their own weight.

[0057] When storing an object to be stored, the control device 400 is configured to determine whether the object is the first object to be stored in the storage channel on this layer according to the warehouse management data. If so, the control device 400 controls the first blocker of the storage channel on this layer to close and the second blocker to open when the object to be stored slides into the storage channel, so that the object to be stored can slide to the first blocker position and be limited by the first blocker. After the object to be stored slides to the first blocker position, the control device 400 controls the second blocker of the storage channel on this layer to close;

[0058] If the object to be stored is not the first one to be stored in the storage passage of the layer (there is at least one object to be stored in the storage passage), the control device 400 controls the first blocker and the second blocker to be closed, and after the object to be stored slides into the storage passage, it is blocked by the second blocker or by the previous object to be stored;

[0059] The control device 400 controls the designated retrieval device 300 to move to the designated storage channel of the designated shelf according to the established retrieval task. After the retrieval device 300 moves to the designated storage channel, the control device 400 controls the first blocker of the storage channel to open, and the retrieval device 300 automatically slides out the taken-out items to the retrieval device 300. Subsequently, the control device 400 controls the retrieval device 300 to transport the items to the designated area according to the established retrieval task.

[0060] After the items at the delivery position of the storage channel on the designated layer are taken out, the control device 400 controls the first blocker to close and the second blocker to open, allowing a subsequent stored item to enter the delivery position area, and then controls the second blocker to close, thereby isolating the delivery position items from the subsequent items.

[0061] This embodiment proposes a multi-layer shelf system, which includes a shelf, a deposit device, a retrieval device and a control device, wherein the shelf includes a multi-layer storage channel, the deposit device can be used to automatically deposit items, and the retrieval device can be used to automatically retrieve items. Each layer of the storage channel is also provided with a first blocker and a second blocker. Through the action of the first blocker and the second blocker, it can be achieved that only the first item slides into the exit retrieval device, and subsequent items do not follow. After the item completely enters the retrieval device, the subsequent items automatically move forward to be replenished. Based on the multi-layer storage channels arranged in the vertical direction, the storage space can be reasonably utilized, and storage can be implemented efficiently and conveniently, and the horizontal surface area can be reduced by 66%. The retrieval of items is automated, convenient, efficient, and safe, and can ensure the first-in-first-out of cartons, and the number of personnel for operation and handling is reduced by 70%.

[0062] exist Figure 1 On the basis of the scheme shown, in one possible implementation scheme, the side and bottom surfaces of each layer of the storage channel are also configured with smooth strips.

[0063] For example, in this solution, the flow strip can be composed of rollers, brackets and tracks. The rollers can be made of plastic or metal, and the shape and size of the rollers can be selected according to different application requirements. The bracket is used to support the rollers and tracks, and is usually made of metal materials. The shape of the track can be linear to meet the transportation requirements of the items.

[0064] Exemplarily, in this solution, based on the inclination angle of the storage channel, when materials are placed on the flow strip, due to the effect of gravity, the items will move along the rolling direction of the roller, thereby improving logistics efficiency.

[0065] Figure 2 is a schematic diagram of the structure of the deposit device in the embodiment, refer to Figure 2 , based on any of the above solutions, in one possible implementation, the depositing device includes a first driving motor 201, a first lifting track 202, a first lifting platform 203, and a first positioning detection device 204;

[0066] The first driving motor 201 is used to drive the first lifting platform 203 to move on the first lifting track 202, and the first lifting platform 203 is used to carry the items to be stored;

[0067] The first positioning detection device 204 detects whether the first lifting platform 203 reaches the storage passage of the designated layer.

[0068] Exemplarily, in this solution, the depositing device is configured as a freight elevator type lifting device, wherein the first driving motor 201 drives the first lifting platform 203 to move along the first lifting track 202 to achieve ascent or descent.

[0069] Exemplarily, in this solution, the first drive motor 201 can adopt an AC asynchronous motor, which has a simple structure, reliable operation, and low cost, and can achieve speed regulation by changing the power supply frequency. Alternatively, a DC permanent magnet motor can be adopted. The DC permanent magnet motor uses permanent magnets as excitation sources, does not require excitation windings and excitation power supplies, has high reliability, and low maintenance costs.

[0070] Exemplarily, in this solution, the first lifting platform 203 can be connected to the first lifting rail 202 through rollers, wherein a special roller mounting seat can be provided on the lifting platform, and the roller is mounted on the mounting seat, and the mounting seat can be fixed to the platform by bolts, welding, etc., and can be adjusted as needed to ensure good cooperation between the roller and the guide rail;

[0071] When the first lifting platform 203 is in operation, the first lifting platform 203 rolls on the guide rails through rollers to achieve lifting motion. The friction between the rollers and the guide rails is small, so that the lifting platform can operate smoothly and can withstand a large load.

[0072] Exemplarily, in this solution, the first positioning detection device 204 may include a plurality of limit switches (LimitSwitch, LS), wherein one or a group of limit switches are correspondingly arranged for each layer of storage passage;

[0073] Exemplarily, the LS switch may include a contact, and the operating head may be a small cylindrical, square protrusion or a larger roller. When the lifting platform reaches a specific position, the operating head may contact or collide with a certain component of the lifting platform, thereby triggering the action of the LS switch;

[0074] Specifically, when the lifting platform moves to the preset floor position, a certain part of the lifting platform (such as the baffle or protrusion fixed on the lifting platform) will come into contact or collide with the contact of the LS switch. The contact will be displaced or rotated after being acted upon by external force, and this displacement or rotation will be transmitted to the moving contact through the transmission mechanism, so that the moving contact contacts the static contact, thereby connecting the circuit;

[0075] At this time, a current signal will be generated in the circuit, and this signal will be transmitted to the control device 400. The control device 400 determines that the lifting platform has reached the corresponding floor according to this signal;

[0076] When the lifting platform leaves this position, the contacts lose the external force and return to their initial position under the action of the reset device. The moving contact separates from the static contact, the circuit is disconnected, and the signal disappears.

[0077] Illustratively, in this solution, a deposit instruction can be manually input into the control device 400, and the number of layers of the storage channel where the items to be stored are to be stored can be determined through the deposit instruction. In addition, the items to be stored can be manually placed on the first lifting platform 203, and when the first lifting platform 203 moves into place, the items to be stored can be manually assisted to enter the storage channel.

[0078] exist Figure 2 On the basis of the scheme shown, in one possible implementation scheme, the first lifting platform is further provided with a first lifting cylinder 205 and a first to-be-stored article in-place detection device 206;

[0079] The first lifting cylinder 205 is used to lift the items to be stored on the first lifting platform 203;

[0080] The first to-be-stored object presence detection device 206 is used to detect whether there is an to-be-stored object on the first lifting platform 203 .

[0081] Exemplarily, in this solution, the first lifting cylinder 205 is a cylinder used to lift the object on the first lifting platform 203, and the cylinder generates a linear motion through the pressure of compressed air, thereby achieving the lifting action of the object;

[0082] The cylinder may include a cylinder barrel, a piston, a piston rod, a seal, a buffer device, and an air inlet and outlet. The interior of the cylinder barrel is the movement space of the piston, and the exterior is used to install other components. The piston is located inside the cylinder barrel and is connected to the piston rod. It is the moving part of the cylinder. The piston rod is a component that connects the piston and external objects. One end of the piston rod is connected to the piston, and the other end extends out of the cylinder barrel to connect objects. The seal is used to ensure the sealing of the cylinder and prevent compressed air leakage. The buffer device is used to reduce the impact and vibration of the piston during movement and protect the cylinder and objects. The buffer device is usually composed of a buffer pad, a buffer sealing ring, etc., and is installed at both ends of the cylinder. The air inlet and outlet are used to connect the compressed air source and the inside of the cylinder to achieve the entry and exit of compressed air;

[0083] When compressed air enters the cylinder from the air inlet, the air pressure acts on the piston, pushing the piston to move linearly in the cylinder. The piston rod extends or retracts with the movement of the piston, thereby driving the external objects to be lifted or lowered. When the compressed air is discharged from the air outlet, the piston returns to its original position under the action of the spring force or the external objects.

[0084] Exemplarily, in this solution, the first to-be-stored item presence detection device 206 may be a photoelectric sensor, a pressure sensor, a proximity sensor, etc.;

[0085] The emitter and receiver of the photoelectric sensor can be installed on opposite sides of the lifting platform. When there is no object on the platform, the light emitted by the emitter can be directly received by the receiver; when an object blocks the light, the receiver cannot receive the light signal, thus judging that there is an object on the platform.

[0086] The emitter and receiver of the photoelectric sensor can also be installed on the same side. After the light emitted by the emitter hits the object on the platform, it is reflected back and received by the receiver. If the receiver receives the reflected light of sufficient intensity, it is judged that there is an object on the platform;

[0087] When an object is placed on the lifting platform, a certain amount of pressure will be generated on the platform. The pressure sensor senses this pressure through the sensing element and converts it into an electrical signal. The signal processing circuit processes the electrical signal and outputs it to the control system, thereby determining that there is an object on the platform;

[0088] When an object approaches the sensing head, the capacitance value between the sensing head and the object will change. After the signal processing circuit detects the change in capacitance value, it outputs a corresponding signal.

[0089] Hall-effect proximity sensors use the Hall effect. When the magnetic field changes, the Hall element outputs a voltage signal. When a magnetic object approaches the sensor head, it changes the magnetic field around the sensor head, causing the Hall element to output a signal to determine that an object is approaching.

[0090] Exemplarily, in this solution, the control device 400 can be configured to, after obtaining the deposit instruction, determine whether there is an object on the first lifting platform 203 according to the detection signal of the first object to be stored detection device 206, and when there is an object, control the first drive motor 201 to drive the first lifting platform 203 to move to a specified number of floors, otherwise, an alarm prompt is issued;

[0091] After the first lifting platform 203 reaches the designated number of floors, the first lifting cylinder 205 is controlled to lift the items on the first lifting platform 203, so that the items slide into the corresponding storage channel by their own weight. When the first to-be-stored item in-place detection device 206 determines that the items have entered the storage channel, the first lifting cylinder 205 is controlled to reset.

[0092] Then, the first driving motor 201 is controlled to drive the first lifting platform 203 to move to the bottom layer.

[0093] Exemplarily, in this solution, the objects to be stored are placed on the first lifting platform 203 manually, and when the first lifting platform 203 moves into place, the objects to be stored are automatically placed into the storage passage.

[0094] exist Figure 2 On the basis of the scheme shown, in one possible implementation, the deposit device further includes a first human body detection device 207 and a first guardrail;

[0095] The first human body detection device 207 is used to detect whether a human body enters the movement area of ​​the first lifting platform 203;

[0096] The first guardrail is disposed outside the movement area of ​​the first lifting platform 203 .

[0097] Exemplarily, in this solution, the first human detection device 207 may be a passive infrared sensor, an active infrared sensor, an ultrasonic sensor, etc.;

[0098] Among them, the passive infrared sensor is used to detect infrared rays of a specific wavelength emitted by the human body. When a human body enters the detection area of ​​the sensor, the intensity of the infrared rays changes. The pyroelectric element of the passive infrared sensor senses this change and generates an electrical signal. The signal processing circuit determines whether there is a human body based on the change in the electrical signal.

[0099] The infrared transmitting tube of the active infrared sensor emits infrared rays to the detection area. When a human body passes by, the infrared rays are reflected back by the human body and received by the infrared receiving tube. The signal processing circuit determines whether there is a human body based on the strength and time difference of the received signal.

[0100] The ultrasonic transmitter transmits ultrasonic signals to the detection area. When a human body passes by, the ultrasonic signal is reflected back by the human body and received by the ultrasonic receiver. The signal processing circuit calculates the distance between the human body and the sensor based on the time difference between the transmitted and received signals, thereby determining whether there is a human body.

[0101] Exemplarily, in this solution, the control device 400 can also be configured to determine whether a person has entered the storage device 200 illegally based on the first human detection device 207. When it is determined that a person has entered by mistake, the storage device 200 can be controlled to stop running immediately to prevent safety problems caused by the person entering by mistake.

[0102] Exemplarily, in this solution, the first guardrail is used to prevent items from falling out of the first lifting platform 203 during transportation and to prevent the first lifting platform 203 from being caught due to human error during movement.

[0103] Figure 3 is a schematic diagram of the structure of the removal device in the embodiment, refer to Figure 3 , based on any of the above solutions, the taking-out device includes a second driving motor 301, a second lifting track 302, a second lifting platform 303, and a second positioning detection device 304;

[0104] The second driving motor 301 is used to drive the second lifting platform 303 to move on the second lifting track 302, and the second lifting platform 303 is used to carry the items to be stored;

[0105] The second positioning detection device 304 detects whether the second lifting platform 304 reaches the storage passage of the designated layer.

[0106] Exemplarily, in this embodiment, the removal device and Figure 2 The structure, corresponding connection relationship and working principle of the deposit device shown are the same;

[0107] The structures, connection relationships and working principles of the second driving motor 301, the second lifting track 302, the second lifting platform 303 and the second positioning detection device 304 are similar to those of the second driving motor 301, the second lifting track 302 and the second lifting platform 303. Figure 2 In the illustrated scheme, the corresponding records of the first driving motor 201, the first lifting track 202, the first lifting platform 203, and the first positioning detection device 204 are the same, and the specific contents are not repeated here.

[0108] Exemplarily, in this solution, a retrieval instruction can be manually input into the control device 400, and the layer number of the storage channel where the item to be retrieved is located is determined by the retrieval instruction. When the second lifting platform 303 moves to the lowest position, the items on the second lifting platform 303 are manually unloaded.

[0109] exist Figure 3 On the basis of the scheme shown, in one possible implementation scheme, the second lifting platform is further provided with a second lifting cylinder 305 and a second to-be-stored article in-place detection device 306;

[0110] The second lifting cylinder 305 is used to lift the objects to be taken out on the second lifting platform 303;

[0111] The second to-be-stored object presence detection device 306 is used to detect whether there are objects to be taken out on the second lifting platform 303 .

[0112] Exemplarily, in this solution, the second lifting cylinder 305, the second to-be-stored object in-place detection device 306 and Figure 2 In the illustrated solution, the corresponding records of the first lifting cylinder 205 and the first to-be-stored object in-place detection device 206 are the same, and the specific contents are not repeated here.

[0113] Exemplarily, in this solution, the control device 400 can be configured to, after obtaining the taking-out instruction, control the second lifting platform 303 to reach the specified number of floors, determine whether there is an object on the second lifting platform 303 according to the detection signal of the second object to be stored detection device 306, and when there is an object, control the second drive motor 301 to drive the second lifting platform 303 to move to the lowest position, otherwise an alarm prompt is issued;

[0114] After the second lifting platform 303 moves to the lowest position, the second lifting cylinder 305 is controlled to lift the items on the second lifting platform 303, so that the items slide out of the second lifting platform 303 due to their own weight. When the second object to be stored in-place detection device 306 determines that the items have slid out of the second lifting platform 303, the second lifting cylinder 305 is controlled to reset.

[0123] The shelf 100 includes multiple layers of storage channels, each layer of storage channels is inclined from a first side to a second side, and the height of the first side is higher than the height of the second side;

[0124] A first blocker 101 and a second blocker 102 are provided on the second side of each layer of the storage channel. The first blocker 101 is used to allow or prevent an object to be stored at the delivery position from entering the taking-out device 300, and the second blocker 102 is used to allow or prevent an object to be stored from entering the delivery position.

[0125] The depositing device 200 includes a first driving motor 201, a first lifting track 202, a first lifting platform 203, a first positioning detection device 204, a first human body detection device 207, and a first guardrail;

[0126] The first lifting platform 203 is also provided with a first lifting cylinder 205 and a first to-be-stored article in-place detection device 206;

[0127] Among them, the first driving motor 201 is arranged at the top of the depositing device 200, the first lifting track 202 is arranged on the frame of the depositing device 200, the first lifting platform 203 is slidably connected with the first lifting track 202, the first positioning detection device 204 is arranged on the frame of the depositing device 200 close to the first lifting track 202, and the first human body detection device 207 is arranged at the bottom of the depositing device 200, on the frame at the object entrance position;

[0128] The taking-out device 300 includes a second driving motor 301, a second lifting track 302, a second lifting platform 303, a second positioning detection device 304, a second human body detection device 307, and a second guardrail;

[0129] The second lifting platform is also equipped with a second lifting cylinder 305 and a second to-be-stored article in-place detection device 306;

[0130] Among them, the second driving motor 301 is arranged at the top of the taking-out device 300, the second lifting track 302 is arranged on the frame of the taking-out device 300, the second lifting platform 303 is slidably connected with the second lifting track 302, the second positioning detection device 304 is arranged on the frame of the taking-out device 300 close to the second lifting track 302, and the second human body detection device 307 is arranged at the bottom of the taking-out device 300, on the frame at the object exit position;

[0131] The control device is respectively connected to the first driving motor 201, the first positioning detection device 204, the first human body detection device 207, the first lifting cylinder 205, the first to-be-stored object in-place detection device 206, the second driving motor 301, the second positioning detection device 304, the second human body detection device 307, the second lifting cylinder 305, and the second to-be-stored object in-place detection device 306.

[0132] Exemplarily, in this solution, the control device adopts a PLC (Programmable Logic Controller), and the control device is configured to include a display screen and buttons, and is configured to manually input specified deposit instructions (determine that items are stored in the storage channel of the specified layer) and retrieval instructions (determine that items are taken out from the storage channel of the specified layer) through operating the buttons.

[0133] Exemplarily, in this solution, a multi-layer shelf system is used for the storage of carton filters. The shelf can be divided into three layers, and the length, width and height of the shelf are about 9m*1.3m*3.5m. Each layer is placed with no less than 10 carton filters (the size of the carton filter is 1200*840*1000mm);

[0134] The shelf support columns are set to 80*80mm square steel, the horizontal structure is 40*40mm square steel, the vertical structure is 40*40mm square steel, the top is 0.5mm rainproof iron plate, and the side is 100mm high iron plate;

[0135] Install 4 sets of #60 smooth strips at the bottom of each shelf layer, and install #40 guide smooth strips on the side. The entire exit side is tilted to allow the cartons to automatically slide toward the exit. The tilt angle is 10 to 15 degrees (it is necessary to ensure that the cartons slide automatically using their own weight, but also to avoid the overall shelf entrance being too high due to a too high tilt angle).

[0136] In this solution, a storage device 200 is provided at the entrance side of the shelf, and the first driving motor 201 drives the first lifting platform 203 to automatically rise and fall. The first lifting platform 203 can be positioned and stopped at the bottom entrance, the 1st floor, the 2nd floor, and the 3rd floor of the shelf, wherein the corresponding 1st floor / 2nd floor / 3rd floor positions are connected with the shelf flow strip;

[0137] A first guardrail is installed around the operating area of ​​the first lifting platform 203. The first guardrail is used to prevent the carton filter from falling during transportation and to prevent people from accidentally touching the driving device and causing clamping. A smooth strip is also set at the bottom of the first lifting platform 203 to facilitate the smooth sliding of the carton.

[0138] In this solution, a take-out device 300 is provided at the shelf exit side, and the second lifting platform 303 is automatically raised and lowered by the second driving motor 301. The second lifting platform 303 can be positioned and stopped at the bottom removal exit, shelf 1st layer, 2nd layer, and 3rd layer, wherein the corresponding 1st layer / 2nd layer / 3rd layer positions are connected with the shelf flow strip;

[0139] A second guardrail is installed around the movement area of ​​the second lifting platform 303. The second guardrail is used to prevent the carton filter from falling and to avoid people accidentally touching the drive and causing clamping. The bottom of the second lifting platform 303 is also a smooth strip to facilitate the carton filter to slide smoothly into the second lifting platform 303 and finally slide out from the second lifting platform 303 to the cart.

[0140] In this solution, when the carton filter is stored, when the first lifting platform 203 stops at the bottom, the staff pushes the carton filter onto the first lifting platform 203;

[0141] After the staff uses the touch control screen at the entrance to select the number of layers to be stored, if the first to-be-stored item in-place detection device 206 detects that there is a carton filter, the control device controls the first drive motor 201 to start, and lifts the first lifting platform 203 upward. When the first lifting platform 203 touches the first positioning detection device 204 of the corresponding layer, the control device controls the first drive motor 201 to stop;

[0142] Then the control device controls the (three) first lifting cylinders 205 to start, lift the rear part of the first lifting platform 203, and make the carton filter automatically slide into the storage channel of the corresponding layer due to its own weight. When the carton filter slides in completely, the first to-be-stored article in-place detection device 206 detects that there is no carton, and the control device controls the first lifting cylinder 205 to return to its original position, and then controls the first drive motor 201 to lower the first lifting platform 203 to the bottom;

[0143] When the carton filter is taken out, the second lifting platform 303 stops at the bottom, and the second to-be-stored object in-place detection device 306 on the second lifting platform 303 detects that there is no carton;

[0144] The staff determines the layer where the carton filter is taken out by touching the control screen, and the control device controls the second driving motor 301 to start, and lifts the second lifting platform 303 upward, and the second lifting platform 303 stops after touching the second positioning detection device 304 of the corresponding layer;

[0145] Then the control device controls the cylinder of the first blocker 101 (set at the front of the carton) to open, and the frontmost carton filter in the corresponding layer storage channel slides into the second lifting platform 303 due to its own weight. When the carton filter completely slides into the second lifting platform 303, the second to-be-stored item in-place detection device 306 detects the existing carton filter, and the first blocker 101 is closed. At the same time, the control device controls the cylinder of the second blocker 102 (set at the bottom of the carton) to open, and subsequent cartons slide forward due to their own weight. When the carton slides to the front end and is blocked by the first blocker 101, after the carton in-place detection device 105 set at this position detects the carton filter, the control device controls the second blocker 102 to close, and the second blocker 102 touches the bottom of the second carton filter and lifts it slightly, so that it cannot slide forward under the premise of relying on its own weight, and therefore subsequent cartons are blocked;

[0146] When the second lifting platform 303 completely slides into the second lifting platform 303, the second to-be-stored article in-place detection device 306 detects that there is a carton filter, and the lift drive motor starts to lower the platform and stops after touching the second positioning detection device 304 at the lowest level;

[0147] Then the control device controls the (three) second lifting cylinders 305 behind the second lifting platform 303 to start, lift the rear part of the second lifting platform 303, and the carton filter automatically slides out of the second lifting platform 303 due to its own weight and enters the export cart. When the second to-be-stored article in-place detection device 306 on the second lifting platform 303 detects that there is no carton filter, the control device controls the second lifting cylinder 305 to return to its original position;

[0148] The first human detection device 207 and the second human detection device 307 are used to prevent people from mistakenly entering and causing safety problems. Once a person touches the equipment during operation, the depositing device 200 and the retrieving device 300 will stop immediately.

[0149] For example, in this solution, there is no limitation on the implementation form of the control program configured in the control device, which can be freely set according to the requirements;

[0150] Taking the control of the deposit device 200 as an example, the control program may include:

[0151] Main program (MAIN): The main program (MAIN) contains the logical framework of the entire program and coordinates the execution of various functions;

[0152] Hoist program block: responsible for the control logic of the hoist motor;

[0153] Cylinder manual control program block: processes the logic related to manual operation of the cylinder;

[0154] Cylinder automatic control program block: realize the control logic of automatic operation of the cylinder;

[0155] Input signal definitions can include:

[0156] Emergency stop button (I0.0): used to stop equipment operation in an emergency;

[0157] Upper limit (I0.5) and lower limit (I0.6): determine the upper and lower limit positions of the hoist (lifting platform);

[0158] Loading layer button (I0.1), first layer button (I0.2), second layer button (I0.3), third layer button (I0.4): used to select the target layer of the elevator ((lifting platform));

[0159] Safety light curtain (I0.7): detects whether there are people or obstacles in the working area to ensure safety;

[0160] Motor switch signal feedback (I1.0): obtain motor switch status information;

[0161] Suspended basket loading layer position switch (I8.0), suspended basket first floor position switch (I8.1), suspended basket second floor position switch (I8.2), suspended basket third floor position switch (I8.3): detect the position of the suspended basket on each floor;

[0162] Weight limiter (I1.3): may be used to detect whether the weight of the lifted item exceeds the limit;

[0163] Input signal definitions can include:

[0164] Motor up (Q0.0), Motor down (Q8.0): Control the forward and reverse rotation of the hoist motor (drive motor) to achieve up and down actions;

[0165] Hanging basket discharge cylinder (Q0.2): controls the telescopic action of the cylinder (lifting cylinder) for loading and unloading materials;

[0166] The hoist motor control logic can be:

[0167] When the emergency stop button is pressed, the motor stops running and the relevant alarm signs may be triggered (such as grating alarm sign M2.0, etc.);

[0168] According to the input of the loading layer button, the first layer button, the second layer button, and the third layer button, combined with the upper limit, lower limit, safety grating, and the status of the position switches on each floor, the motor is controlled to rise or fall, so that the hanging basket can accurately reach the target floor;

[0169] For example, when a button for one layer is pressed and the corresponding safety conditions are met, the motor starts to descend until the position switch for one layer is triggered;

[0170] Cylinder manual control logic:

[0174] After reaching the discharge position, the start and discharge time of the cylinder are controlled by the timer (such as the start of the hanging basket in place: T37, the discharge completion timing: T40, etc.) to realize the automatic discharge operation;

[0175] During the whole process, safety signals such as safety gratings and emergency stop buttons are always involved in the control logic to ensure the safe operation of the equipment. At the same time, the motor up and down signals also cooperate with the cylinder control logic. For example, after the material is discharged, the motor is controlled to rise or fall as needed to facilitate the next loading operation.

[0176] Data storage and processing:

[0177] Multiple intermediate variables (such as M2.0, M3.0, M3.1, M3.2, M4.0, M4.1, M4.2, M6.0, M7.0, M7.1, M7.2, etc.) and timers (T37, T38, T40, etc.) are used to store and process status information and time control information during program execution.

[0178] Data storage and processing: Through the MOV_W instruction, some input signals (such as emergency stop button, motor up and down status, grating alarm flag, motor switch signal feedback, etc.) are stored in a specific data storage area (such as VW0, VW2, etc.) for further logical judgment and processing in the program.
