Description

[0001] This application is a divisional application of Chinese patent application No. 202311362779.7, filed on October 19, 2023, entitled "A takeaway food pickup system and method". Technical Field

[0002] This invention relates to the field of food delivery pickup, specifically a method for picking up food delivery orders. Background Technology

[0003] Food delivery refers to the sale of goods for customers to take away from the store. With the widespread use of telephones, mobile phones, and the internet, the food delivery industry has developed rapidly, and the number of online food delivery users in China has been growing year by year. When delivering food, since some residential areas, office buildings, and schools do not allow delivery personnel to enter, food delivery lockers are provided for storing food.

[0004] Existing food delivery lockers, as described in patent number "CN218004172U", have evenly spaced storage compartments for food delivery. This storage method has the following problems: 1. During peak hours, delivery drivers and customers gather in front of the lockers, causing congestion and low efficiency; 2. Different food delivery items have different sizes, while the storage compartments are all the same size. Many small food delivery items can only be stored in compartments that are much larger than themselves, resulting in extremely low space utilization of the lockers. Therefore, this problem urgently needs to be solved. Summary of the Invention

[0005] To avoid and overcome the technical problems existing in the prior art, the present invention provides a method for picking up takeout food. The present invention significantly improves the efficiency of takeout food pickup and has a high space utilization rate when storing takeout food.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A method for picking up takeout food includes the following steps:

[0008] S1. The delivery person scans the food delivery code at the storage area and generates a pickup code to send to the customer.

[0009] The takeout area is equipped with takeout shelves, storage slots, and retrieval slots located within the range of the storage and retrieval robot arm. The robot arm is equipped with a card storage mechanism and a card retrieval mechanism that move synchronously with the robot arm. The card storage mechanism is used to store identification cards that can emit different colors of light, and the card retrieval mechanism is used to retrieve the identification cards from the card storage mechanism. The identification cards are placed on the takeout shelf by the card retrieval mechanism along with the takeout to indicate the location of the corresponding takeout.

[0010] S2. The storage and retrieval robot takes out the takeout from the storage slot, and the card retrieval mechanism simultaneously takes out the identification card, so that the card face is arranged vertically.

[0011] S3. The storage and retrieval robot transfers the takeout to the corresponding layer above the takeout rack, so that the position of the identification card corresponds to the position of the card slot on the takeout rack. The storage and retrieval robot descends to place the takeout smoothly. While the storage and retrieval robot moves the takeout down, the identification card is inserted into the card slot of the takeout rack and thus disengages from the card retrieval mechanism.

[0012] S4. When a customer picks up their food, after clicking "pick up food" on their mobile phone, the identification card emits a designated color light to serve as an identifier. The storage and retrieval robotic arm moves to the corresponding takeout location, and while the card retrieval mechanism absorbs the identification card, the storage and retrieval robotic arm picks up the takeout. After the storage and retrieval robotic arm moves upward as a whole, it pulls the identification card out of the card slot of the takeout rack and causes the takeout to detach from the takeout rack.

[0013] S5. The robotic arm transfers the takeout to the pickup point, and the card retrieval mechanism puts the identification card back into the card storage mechanism.

[0014] S6. Customers scan the code at the pickup point to pick up their food and complete the pickup process.

[0015] As a further aspect of the present invention: in step S4, customers can quickly find the location of their takeout order by customizing the color of the identification card emitted by their mobile phones; the identification card can continuously emit monochromatic light or alternately emit different colors of light.

[0016] As a further aspect of the present invention: the card storage mechanism includes a card compartment mounted on a fixed base, with an opening at the top of the card compartment for the identification cards to be stacked from bottom to top inside the card compartment; a lifting module is arranged on the fixed base, which can lift the identification cards inside the card compartment in the vertical direction.

[0017] As a further embodiment of the present invention: the lifting module is a drive screw arranged in the vertical direction, and a bracket that abuts against the identification card at the bottom of the card compartment is fixed on the nut seat of the drive screw; a sensor for detecting the lifting height of the identification card is also installed on the fixed base.

[0018] As a further embodiment of the present invention: the card retrieval mechanism includes a mounting base arranged on the robotic arm of the storage and retrieval robot and located above the card compartment. A sliding seat is arranged on the mounting base and slides vertically with the mounting base. An electric push rod is mounted on the mounting base, capable of driving the sliding seat to slide vertically. A rotating rod passes through the sliding seat and rotates with it, with its rotation axis perpendicular to the direction of the electric push rod's movement. A positioning rod passes through the rotating rod along a direction perpendicular to its axis and slides with it. A suction cup for adsorbing identification cards is mounted on the end of the positioning rod away from the rotating rod. A return spring is coaxially sleeved on the positioning rod, with both ends of the return spring abutting against the suction cup and the body of the rotating rod, respectively. An S-shaped guide groove is provided on the mounting base. A guide rod arranged parallel to the rotating rod passes through the guide groove and slides with it. The guide rod is connected to the rotating rod via a connecting rod and drives the rotating rod to rotate when sliding along the guide groove, thereby switching the card face orientation of the identification card.

[0019] As a further aspect of the present invention: the takeaway rack is provided with a refrigerated layer, a frozen layer, a room temperature layer and a heated layer; after the takeaway food is picked up by the storage and retrieval robot, it is arranged in sequence on each layer of the takeaway rack, and each layer of the takeaway rack has a slot along the vertical direction for the insertion of identification cards from top to bottom.

[0020] As a further embodiment of the present invention: X-axis guide rail, Y-axis guide rail and Z-axis guide rail are installed in the takeaway area. The X-axis guide rail, Y-axis guide rail and Z-axis guide rail cooperate with each other to form a three-axis displacement platform. The storage and retrieval robot is mounted on the Y-axis guide rail through a rotating seat. The rotation axis of the rotating seat is arranged vertically.

[0021] As a further aspect of the present invention: the takeaway area is a square frame-like area enclosed by profiles, and a conveyor belt for receiving takeaways taken from the takeaway rack is installed at the pick-up port. The conveyor belt is arranged parallel to the takeaway rack and the pick-up port is located at the end of the conveyor belt.

[0022] As a further aspect of the present invention: multiple sets of pickup ports are arranged at intervals on the side of the conveyor belt to facilitate the diversion of people picking up goods; a storage barcode scanner is installed at the storage port for scanning codes for takeout orders and generating pickup codes.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention sets up staggered storage and retrieval slots and takeout racks in the takeout area. Takeout is stored and retrieved by a robotic arm, which separates the delivery personnel and the pick-up personnel, avoids congestion during peak hours, and greatly improves the efficiency of picking up food. When picking up food, there are no compartments on the takeout rack, and takeout can be arranged closely together in sequence. After the takeout is placed on the takeout rack, a light-emitting identification card can be placed at the front of the takeout. When the customer scans the code to pick up the food, the identification card lights up to prompt the customer to quickly find the location of the takeout. The robotic arm retrieves the food to the retrieval slot and waits for the customer to pick up the food.

[0025] 2. The card storage mechanism and card retrieval mechanism of the present invention are both installed on the storage and retrieval robot arm and move synchronously with the robot arm; when the storage and retrieval robot arm stores the takeout on the takeout rack, the drive screw lifts the identification card in the card compartment through the bracket, so that the subsequent card retrieval mechanism can retrieve the card and place it on the takeout rack to mark the takeout location; the lifting height of the identification card can be controlled in real time through the detection of the sensor, which facilitates the card retrieval operation.

[0026] 3. In this invention, the electric push rod drives the sliding seat to move downwards, thereby driving the suction cup to pick up the identification card via the positioning rod. After picking up the identification card, the electric push rod drives the sliding seat to move upwards, and at the same time drives the guide rod to change direction via the guide groove, thereby driving the positioning rod to rotate 90 degrees, so that the card surface of the identification card rotates from a horizontal state to a vertical arrangement. At this time, the card surface of the identification card can be positioned directly opposite the takeaway rack. When the storage and retrieval robot arm drives the takeaway down, the identification card is inserted into the card slot of the takeaway rack, thereby detaching from the suction cup of the card retrieval mechanism, thus serving as an identification function in front of the corresponding takeaway. When picking up the food, customers can also customize the identification card to emit single-color light or alternate different colors of light to improve the recognition.

[0027] 4. This invention forms a three-axis displacement platform through the cooperation of X-axis guide rail, Y-axis guide rail and Z-axis guide rail, and drives the storage and retrieval robot to rotate through the rotating seat, which greatly improves the range of motion of the storage and retrieval robot; after the storage and retrieval robot retrieves the food, it can be transported by the conveyor belt, which facilitates the subsequent diversion and retrieval operations; different temperature zones can be arranged on the takeaway rack to facilitate the storage of different types of takeaway food.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1-5 In this embodiment of the invention, a method for picking up takeout food is provided. The takeout area 1 is a square frame-shaped area formed by enclosing profiles. The storage port 122, the pickup port 131, and the takeout rack 11 are respectively arranged on one side of the takeout area 1, thus being staggered from each other. The takeout rack 11 and the pickup port 131 are opposite each other in front and behind within the takeout area 1, respectively arranged on the front and back sides of the takeout area 1.

[0044] A barcode scanner 121 is installed at the storage port 122 for scanning food delivery codes and generating a pickup code to send to the customer. After scanning the food delivery code, the customer waits at the storage port 122 for the storage robot 14 to pick it up.

[0045] A conveyor belt 132 for transporting takeout food is arranged along the length of the side where the takeout port 131 is located in the takeout area 1. Multiple sets of takeout ports 131 can be arranged along the direction of the conveyor belt 132 to divert the takeout flow. Multiple sets of storage and retrieval robotic arms 14 can be arranged along the length of the takeout area 1 to improve storage and retrieval efficiency. A barcode scanner can be installed at the storage port 122 for customers to scan the code. After scanning, the storage and retrieval robotic arms 14 take the takeout food from the takeout rack 11 and send it to the conveyor belt 132.

[0046] The takeout rack 11 has multiple layers for layered storage of takeout orders. To improve storage efficiency, each layer of the takeout rack 11 is configured with a refrigerated layer, a frozen layer, a room temperature layer, and a heated layer to accommodate different types of takeout orders. There are no gaps between the layers of the takeout rack 11, allowing takeout orders to be arranged closely along each layer to fully utilize the space. Preferably, the temperature of each layer of the takeout rack 11 increases or decreases sequentially from bottom to top to avoid heat interference.

[0047] An X-axis guide rail 141, a Y-axis guide rail 143, and a Z-axis guide rail 142 are installed at the center of the takeout area 1. These three guide rails cooperate to form a three-axis displacement platform. A storage / retrieval robot 14 is mounted on the Y-axis guide rail 143 via a rotating base 144, with the rotation axis of the rotating base 144 arranged vertically. The robotic arm of the storage / retrieval robot 14 is fixed to the rotating base 144, allowing it to reach the storage slot 122, the retrieval slot 131, and the takeout shelf 11 as the rotating base 144 rotates and the three-axis displacement platform moves. The storage / retrieval robot 14 can operate in any manner, including lifting and gripping.

[0048] The robotic arm of the storage and retrieval robot 14 is equipped with a card storage mechanism 15 and a card retrieval mechanism 16. The card storage mechanism 15 includes a fixed base 151 and a cover-shaped card compartment 153 mounted on the fixed base 151. The top of the card compartment 153 is open, and identification cards 165 that can emit different colors of light are stacked vertically inside the card compartment 153. A lifting module 152 for lifting the identification cards 165 is mounted on the bottom of the fixed base 151. The form of the lifting module 152 is not limited, but it is preferably a vertically arranged drive screw 1521. A bracket 1522 is mounted on the nut seat of the drive screw 1521. The bracket 1522 is located directly below the card compartment 153 and is used to lift the identification cards 165 at the bottom of the card compartment from bottom to top. A sensor is also installed on the mounting base 151 to detect the lifting height of the identification card 165. When the identification card 165 is below the specified height, the bracket 1522 lifts the identification card 165 to facilitate subsequent card retrieval. The identification card 165 is in a horizontal position in the card compartment. A wireless charging module can be installed in the card compartment 153 to wirelessly charge the identification card 165 or charge it with a charging base to ensure stable illumination.

[0049] The card retrieval mechanism 16 includes a mounting base 168 arranged on the robotic arm of the storage and retrieval robot 14 and located above the card compartment 153. A sliding seat 162 is arranged on the mounting base 168 and slides with the mounting base 168 in the vertical direction. An electric actuator 161 is mounted on the mounting base 168 and can drive the sliding seat 162 to slide in the vertical direction. The electric actuator 161 can be replaced with other linear drive components.

[0050] The rotary rod 163 passes through the sliding seat 162 and rotates with the sliding seat 162. The rotation axis is perpendicular to the direction of the electric actuator 161. It can be understood that after the rotary rod 163 passes through the sliding seat 162 in a direction perpendicular to the seat surface of the sliding seat 162, it can rotate around its own axis.

[0051] The positioning rod 167 passes through the rotating rod 163 along the axis of the vertical rotating rod 163 and slides with it. A suction cup 164 for attaching the identification card 165 is installed at the end of the positioning rod 167 away from the rotating rod 163. A return spring 166 is coaxially sleeved on the positioning rod 167, with both ends of the return spring 166 abutting against the suction cup 164 and the rod body of the rotating rod 163, respectively. Figure 2 As shown, in the first working state, while the electric actuator 161 drives the sliding seat 162 downward, the suction cup 164 on the positioning rod 167 adsorbs the identification card 165 in the card compartment 153 by applying downward pressure, and then moves upward to suck out the identification card.

[0052] The mounting base 168 has an S-shaped guide groove 1681. The "S-shape" can be understood as the guide groove 1681 having two parallel channels arranged vertically and staggered in height, connected by an arc-shaped transition channel. A guide rod 1621, arranged parallel to the rotary rod 163, passes through the guide groove 1681 and can slide along it. The guide rod 1621 is connected to the rotary rod 163 via a connecting rod and drives the rotary rod 163 to rotate when sliding along the guide groove 1681. Figure 3 As shown, in the second working state, while the electric push rod 161 drives the sliding seat 162 to move upward, it drives the guide rod 1621 to change direction through the guide groove 1681, thereby driving the positioning rod 167 to rotate ninety degrees, so that the card surface of the identification card 165 rotates from the horizontal state to the vertical arrangement of the card surface. At this time, the card surface of the identification card 165 can be arranged directly opposite the takeaway rack 11.

[0053] When picking up food using a delivery method, the process includes the following steps:

[0054] S1. The deliveryman scans the food delivery code at the storage slot 122 and generates a pickup code to send to the customer.

[0055] S2. The storage and retrieval robotic arm 14 retrieves the takeout order from the storage slot 122, and the card retrieval mechanism 16 passes through... Figure 2 and Figure 3 In both working states, the identification card 165 is retrieved simultaneously, changing the card surface of the identification card 165 from a horizontal arrangement to a vertical arrangement.

[0056] S3. The storage and retrieval robot 14 transfers the takeout to the corresponding layer above the takeout rack 11, so that the position of the identification card 165 corresponds to the position of the card slot on the takeout rack 11. The storage and retrieval robot 14 descends to place the takeout smoothly. While the storage and retrieval robot 14 drives the takeout to descend, the identification card 165 is inserted into the card slot of the takeout rack 11 and thus disengages from the suction cup 164 of the card retrieval mechanism 16.

[0057] S4. When a customer picks up their food, they tap "pick up" on their phone. The identification card 165 emits a designated color light to indicate the location of the takeout on the takeout rack 11. The storage and retrieval robot arm 14 moves to the corresponding takeout location. While the card retrieval mechanism 16 absorbs the identification card 165, the storage and retrieval robot arm 14 picks up the takeout. After the storage and retrieval robot arm 14 moves upward, it pulls the identification card 165 out of the card slot in the takeout rack 11, causing the takeout to detach from the takeout rack 11.

[0058] Customers can quickly locate their takeout order by customizing the color of light emitted by the identification card 165 using their mobile phones; the identification card 165 can continuously emit a single color of light or alternate between different colors of light. After being removed, the identification card 165 can be reinserted into the card holder 153.

[0059] S5. The storage and retrieval robot 14 transfers the takeout to the pickup port 131, and the card retrieval mechanism 16 puts the identification card 165 back into the card storage mechanism 15.

[0060] S6. Customers scan the code at pick-up point 131 to pick up their food and complete the pickup process.
