Description
Technical Field
[0001] This utility model relates to the field of boxed meal machine technology, specifically to a boxed meal machine feeding device with detection function. Background Technology
[0002] Vending machines are a sales model that is not limited by time or location, saves manpower, and facilitates transactions. Common vending machines are divided into four types: beverage vending machines, food vending machines, general vending machines, and cosmetics vending machines. With the fast pace of life, vending machines selling boxed meals, also known as lunchbox machines, are becoming increasingly widespread, allowing ordinary workers, especially white-collar workers, to quickly complete their meals within a short lunch break.
[0003] Unlike vending machines for beverages and general packaged foods, meal vending machines present challenges related to heating and maintaining the temperature of the meals, shelf life, and spoilage. Existing vending machines primarily include smart vending machines, serpentine or curved aisle vending machines, spring-loaded drawer vending machines, and vertical stacking vending machines. While smart vending machines allow customers to scan a code to open the cabinet and select items freely, for items like meal boxes that require constant temperature storage and have a short shelf life, repeated opening and closing of the cabinet door can cause the internal temperature to drop below the required level, compromising storage and sales requirements. Furthermore, the fluctuating temperature environment created by repeated door opening and closing significantly shortens the product's shelf life. Snake-shaped or curved-lane vending machines use curved metal cavities for their dispensers, making them unsuitable for larger boxed meals. Furthermore, their dispensing method, like a magazine, involves discharging items one after another, relying on gravity to slide down from top to bottom. This layering of products in the dispenser hinders heat dissipation, making it impossible to maintain a constant temperature for all meals. Additionally, their complex structure limits their applicability and increases their cost. Spring-loaded drawer vending machines use spring-loaded spiral channels to push beverages or food forward. These spiral channels cannot handle rectangular boxed meals, and the direct downward drop of materials can easily cause film-packaged meals to break and leak due to impact. Vertical stacking vending machines, with items piled close together, tend to heat up quickly at the edges while those in the center heat up slowly and unevenly, failing to ensure all meals are at the same constant temperature, leading to inconsistent heating quality. Therefore, existing vending machines are only suitable for packaged foods such as beverages and snacks. Even with the addition of a heating system, they cannot fully meet the requirements for automatic vending of boxed meals, which is quite challenging. Therefore, it is very important to change the storage and dispensing structure of boxed meals.
[0004] Currently, the method of combining tracked cargo channels with push plates for material feeding is more suitable for storing and discharging boxed meals with cuboid or cylindrical structures and has been put into use. However, the required pushing force varies depending on the number of boxed meals stacked, making it impossible to precisely set the pushing force and thus unable to accurately control the feeding. Furthermore, the stacking also presents the problem of uneven heating. Setting up corresponding partitions between each boxed meal would inhibit the pushing action, thus failing to provide a practical solution.
[0005] Therefore, the research objective of this utility model is to design a lunchbox machine feeding device with detection function that ensures smooth delivery of boxed meals, stores and drives the boxed meals through a conveyor belt, combines a support mechanism for tilting and isolating the boxed meals, utilizes the lifting characteristics of the support mechanism to control the stable support and individual directional dispensing of the boxed meals, and can determine the leakage and swelling of the boxed meals through pressure measurement to ensure sales quality and reduce after-sales problems. Utility Model Content
[0006] In view of the technical problems existing in the prior art, the present invention provides a lunchbox machine feeding device with detection function, which can effectively solve the technical problems existing in the prior art.
[0007] The technical solution of this utility model is:
[0008] A food delivery machine feeding device with detection function includes:
[0009] The tracked cargo path is driven by a corresponding drive motor. On the tracked cargo path, there are a number of positioning components that move with the tracked cargo path and are fixedly installed at equal intervals. The positioning components are equipped with a support mechanism that can be raised and lowered by corresponding elastic elements. When the support mechanism moves upward, it is used to support the tilted lunch box. When it moves downward, it makes way for the lunch box.
[0010] The receiving mechanism includes a receiving box that can move up and down and left and right between the front of the discharge end of each conveyor belt and the food dispensing port of the boxed meal machine. The receiving box has a food outlet and a food inlet on opposite sides facing the food dispensing port of the boxed meal machine.
[0011] The control mechanism, in conjunction with the elastic element, is used to control the up-and-down movement of the support mechanism. After the receiving box moves to the front side of the discharge end of the corresponding track, the control mechanism controls the support mechanism to move down to make room, and the elastic element is compressed.
[0012] The detection mechanism is installed on the top of the receiving box. When the detection mechanism presses against the boxed meal placed in the receiving box through a downward fixed stroke S1 and the pressure value is measured to be within the range of the set value F1-F2, the detection mechanism resets and the receiving box moves towards the food dispensing port of the boxed meal machine. When the measured pressure value is less than the set value F1 or greater than the set value F2, an alarm is issued.
[0013] The detection mechanism includes a pressure plate installed below the top of the receiving box body by being driven up and down by a corresponding small cylinder. A pressure sensor is installed on the lower side of the pressure plate through an elastic pad. A material sensor electrically connected to the small cylinder is provided inside the receiving box body. When the material sensor senses the material and transmits a signal, the piston rod of the small cylinder extends out by a set stroke S1. When the pressure sensor detects that the pressure value is within the range of set values F1-F2, the receiving box body moves towards the food dispensing port of the boxed meal machine.
[0014] The lower side plate of the receiving box is inclined downward from the inlet to the outlet, forming a V-shaped receiving groove. The small cylinder is perpendicular to the lower side plate of the receiving box.
[0015] The food dispensing port of the receiving box is equipped with a corresponding opening and closing plate that can swing or move up and down via a corresponding lifting cylinder driven by a corresponding power motor. The power motor or lifting cylinder is fixedly installed on the receiving box. When the receiving box moves to the food taking port, the power motor or the lifting cylinder drives the opening and closing plate to rotate or move upward to make way, and the food dispensing port is connected to the food taking port of the boxed meal machine.
[0016] The lower side plate of the receiving box is hinged to the receiving box on one side of the food inlet, and a power cylinder for driving the lower side plate to rotate up and down is installed on the opposite side below it.
[0017] A corresponding spare box is fixed above the receiving box. A corresponding detection mechanism is also installed below the top of the spare box. When the pressure sensor inside the receiving box detects that the pressure value is less than the set value F1 or greater than the set value F2, an alarm is issued, and the receiving box moves down to the front of the spare box and is placed at the front end of the track conveyor for re-discharging.
[0018] The top of the positioning component is fitted with the elastic element through an inwardly recessed through hole. The support mechanism includes a limiting component with a C-shaped cross-section that is fixedly installed on the top of the positioning component. An iron support component that can be raised and lowered and is located inside the limiting component is supported by the elastic element. One end of the elastic element is fixedly installed in the through hole, and the other end is fixed to the lower surface of the iron support component. When the lunch box is placed at an angle between two adjacent positioning components above the track, the end of the lunch box abuts against the front end of the rear positioning component, and the bottom of the lunch box abuts against the iron support component installed above the front positioning component.
[0019] The tracked cargo channel includes a cargo channel body and a conveyor belt sleeved around the cargo channel body. The front and rear ends of the cargo channel body are respectively rotatably mounted with a driven shaft and a drive shaft, and the drive shaft is fixedly connected to the output shaft end of the drive motor. The positioning component is fixedly mounted on the surface of the conveyor belt by adhesive bonding.
[0020] The control mechanism includes an electromagnet fixedly installed on the rear side of the discharge end of the tracked cargo channel, a ranging tag fixedly installed on the surface of the driven shaft at the discharge end of the tracked cargo channel, and a photoelectric sensor adapted to the ranging tag. The photoelectric sensor and the electromagnet are both electrically connected to the control system. When the receiving box moves to the discharge end of the corresponding tracked cargo channel, the drive motor is activated and drives the tracked cargo channel to rotate in the forward direction. When the number of times the photoelectric sensor senses the ranging tag is n, where n≥2, the drive motor stops, and the electromagnet is energized to attract the iron support member, which moves down and is placed inside the limiting member to form a clearance, and the elastic member is compressed.
[0021] The tracked cargo passage is provided with corresponding partitions at intervals on both sides.
[0022] Advantages of this utility model:
[0023] 1) This utility model uses a tracked conveyor for transporting boxed meals. Numerous positioning components are installed at intervals along the track. Each positioning component is supported by an elastic element, and a vertically movable iron support component with a C-shaped internal limiter is installed within it. The boxed meals are placed at an angle between adjacent positioning components, with the end of the meal abutting the front end of the rear positioning component and the bottom abutting the iron support component installed above the front positioning component. This support method isolates and secures the boxed meals. Compared to simple isolation using fixed partitions, the placement of the iron support component can be controlled by whether an electromagnet is energized. The device uses the positional changes of iron support components to alter the center of gravity of the lunchbox, thereby shifting the center of gravity for feeding. The lunchbox is fed into the receiving box in an arc, with the receiving end as the center, ensuring the back of the lunchbox is oriented onto the receiving box with the front facing upwards, facilitating subsequent inspection. Feeding is achieved by using an electromagnet to attract and move the corresponding iron support components downwards. Compared to push-type feeding, this invention improves the accuracy and convenience of feeding while ensuring smooth lunchbox delivery. Furthermore, the single-direction feeding method saves time and effort, enhancing the practical effect of this invention.
[0024] 2) This utility model utilizes the adjustment setting of the number of rotations of the driven shaft of the conveyor belt when the positioning component moves one station. By sensing the number of times the distance measuring tag installed on the driven shaft is detected by a photoelectric sensor, the displacement distance of the positioning component is precisely controlled, thereby ensuring that the electromagnet is placed directly below the iron support component. When the electromagnet is energized, it drives the iron support component to move down to create space for the boxed meals to be unloaded. The boxed meals are supported by a single force and driven to be unloaded by a single drive, without affecting each other. Moreover, no matter how many boxed meals are placed on the conveyor belt, the speed of the drive motor does not affect the unloading, thus making the unloading more labor-saving and precise.
[0025] 3) This utility model uses gear transmission to drive the receiving box to move left and right, and uses screw transmission to drive the receiving box to move up and down. This facilitates the stable movement of the receiving box between the front end of each conveyor belt and the food pick-up port, and transports the boxed meals. Compared with the direct drop method of pushing materials, this utility model can effectively shorten the distance the boxed meals fall by using the receiving box, thus protecting the boxed meals and preventing them from being torn and leaking or deformed due to impact from falling from a height, which would affect sales. In addition, a corresponding detection mechanism is set below the top of the receiving box. The extension stroke S1 of the piston rod is set according to the different pressures of the boxed meals. The pressure sensor installed at the end of the piston rod detects the pressure value. If the pressure value is between the set value F1 and F2, it can be determined that the boxed meals are not leaking air (the air leakage pressure value is less than F1) or not bulging (the bulging pressure value is greater than F2), thus ensuring that the boxed meals transported out are in good condition, ensuring the quality of the boxed meals sold, and reducing after-sales problems.
[0026] 4) The lower side plate of the receiving box of this utility model is inclined downward from the inlet to the outlet, forming a V-shaped receiving groove. When the boxed meal is unloaded from the conveyor belt onto the receiving box, the inclined surface and gravity promote the boxed meal to move into the receiving box and leave the conveyor belt, thereby improving the smoothness of unloading and receiving; and promotes the boxed meal to move down along the inclined surface to the pick-up point, making it convenient for people to pick up the meal.
[0027] 5) In this utility model, a corresponding closing plate is installed at the food outlet of the receiving box by driving a drive motor to rotate or a lifting cylinder to move up and down. The closing plate can not only block the food outlet when the receiving box receives food, effectively preventing the food from falling out of the food outlet and protecting the food; but also block the food outlet when the receiving box returns to the food pick-up opening, so there is no need to add a corresponding anti-theft mechanism at the food pick-up opening.
[0028] 6) This utility model has a spare box with the same structure above the receiving box, and the same detection mechanism is installed in the spare box. When the receiving box receives a boxed meal with a leaking or bulging bag, it can quickly and promptly provide the customer with a new boxed meal. In addition, a temporary storage area for defective boxed meals is specially set up, and the bottom of the receiving box is set to be hinged. It can be driven to rotate by a lifting cylinder, and then the defective boxed meals are transferred to the temporary storage area by lifting the lower side plate for temporary storage until the staff handles them. This ensures that the receiving mechanism can still be used. The closing plate of the temporary storage area is installed by using a torsion spring and a rotating shaft, and is equipped with a corresponding sealing strip to ensure that the temporary storage area is normally closed and effectively isolated from the storage area, so as to prevent defective boxed meals from having an adverse effect on normal boxed meals or boxed meal machines, thereby improving the user experience of this utility model.

[0035] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:
[0036] Example 1
[0037] refer to Figure 1-5 A food delivery machine feeding device with detection function, comprising:
[0038] The tracked cargo lane 1 is driven by a corresponding drive motor 2. A number of positioning components 3 are fixedly installed at equal intervals on the track surface of the tracked cargo lane 1, which move with the tracked cargo lane 1. The positioning components 3 are equipped with a support mechanism that can be raised and lowered by a corresponding elastic component 4. When the support mechanism moves upward, it is used to support the tilted lunch box. When it moves downward, it makes way for the lunch box.
[0039] The receiving mechanism includes a receiving box 5 that can move up and down and left and right and is located between the front side of the discharge end of each conveyor belt 1 and the food taking port of the boxed meal machine. The receiving box 5 has a food outlet and a food inlet on opposite sides facing the food taking port of the boxed meal machine.
[0040] The control mechanism, in conjunction with the elastic element 4, is used to control the up-and-down movement of the support mechanism. After the receiving box 5 moves to the front side of the discharge end of the corresponding track 1, the control mechanism controls the support mechanism to move down to make room, and the elastic element 4 is compressed.
[0041] The detection mechanism is installed on the top of the receiving box 5. When the detection mechanism presses against the boxed meal placed in the receiving box 5 through a downward fixed stroke S1 and the pressure value is measured to be within the range of the set value F1-F2, the detection mechanism resets and the receiving box 5 moves towards the food dispensing port of the boxed meal machine; when the measured pressure value is less than the set value F1 or greater than the set value F2, an alarm is issued.
[0042] The detection mechanism includes a pressing plate 7 installed below the top of the receiving box 5, driven up and down by a corresponding small cylinder 6. A pressure sensor 9 is installed on the lower side of the pressing plate 7 via an elastic pad 8. A material sensor electrically connected to the small cylinder 6 is provided inside the receiving box 5. The material sensor can be a photoelectric sensor or other sensor used to sense the arrival of the boxed meal. When the material sensor senses the material and transmits a signal, the piston rod of the small cylinder 6 extends a set stroke S1. When the pressure sensor 9 detects that the pressure value is within the set value range F1-F2, the receiving box 5 moves towards the food dispensing port of the boxed meal machine.
[0043] This invention uses gear transmission to move the receiving box 5 left and right, and screw transmission to move it up and down. This facilitates the stable movement of the receiving box 5 between the front end of each conveyor belt 1 and the food pick-up port, transporting the boxed meals. Compared to the direct drop method of pushing materials, this invention effectively shortens the distance the boxed meals fall, thus protecting them and preventing them from breaking and leaking or deforming due to impact from a high drop, which would affect sales. Furthermore, a corresponding detection mechanism is set below the top of the receiving box 5. The small cylinder 6 sets the extension stroke S1 of the piston rod according to the different pressures of the boxed meals. The pressure sensor 9 installed at the end of the piston rod detects the pressure value. If the pressure value is between the set value F1 and F2, it can be determined that the boxed meals are not leaking air (leakage pressure value is less than F1) or not bulging (bulging pressure value is greater than F2), thus ensuring that the boxed meals transported out are in good condition, ensuring the quality of the boxed meals sold, and reducing after-sales problems.
[0044] The lower side plate of the receiving box 5 is inclined downward from the inlet to the outlet, forming a V-shaped receiving groove. The small cylinder 6 is perpendicular to the lower side plate of the receiving box 5.
[0045] The lower side plate of the receiving box 5 of this utility model is inclined downward from the inlet to the outlet, forming a V-shaped receiving groove. When the boxed meal is unloaded from the conveyor belt 1 onto the receiving box 5, the inclined surface and gravity promote the boxed meal to move into the receiving box 5 and detach from the conveyor belt 1, thereby improving the smoothness of unloading and receiving; and promotes the boxed meal to move down along the inclined surface to the pick-up point, making it convenient for people to pick up the meal.
[0046] The food dispensing port of the receiving box 5 is equipped with a corresponding opening and closing plate 11 that can swing or move up and down via a corresponding lifting cylinder driven by a corresponding power motor 10. The power motor 10 or the lifting cylinder is fixedly installed on the receiving box 5. When the receiving box 5 moves to the food taking port, the power motor 10 or the lifting cylinder drives the opening and closing plate 11 to rotate or move upward to make way, and the food dispensing port is connected to the food taking port of the boxed meal machine.
[0047] This invention installs a corresponding closing plate at the food outlet of the receiving box 5 by driving the rotation of the drive motor 2 or moving up and down by the lifting cylinder. The closing plate not only blocks the food outlet when the receiving box 5 receives food, effectively preventing the food from falling out of the food outlet and protecting the food; but also blocks the food outlet when the receiving box 5 returns to the food retrieval opening, eliminating the need for additional anti-theft mechanisms at the food retrieval opening.
[0048] The lower side plate of the receiving box 5 is hinged to the receiving box 5 on one side of the food inlet, and a power cylinder 19 for driving the lower side plate to rotate up and down is installed on the opposite side below it.
[0049] The top of the positioning member 3 is fitted with the elastic member 4 through an inwardly recessed through hole. The support mechanism includes a limiting member 17 with a C-shaped cross-section, which is fixedly installed on the top of the positioning member 3. An iron support member 18, which can be raised and lowered and is located inside the limiting member 17, is supported by the elastic member 4. One end of the elastic member 4 is fixedly installed in the through hole, and the other end is fixed to the lower surface of the iron support member 18. When the lunch box is placed at an angle between two adjacent positioning members 3 above the track chute 1, the end of the lunch box abuts against the front end of the rear positioning member 3, and the bottom of the lunch box abuts against the iron support member 18 installed above the front positioning member 3.
[0050] This invention uses a tracked conveyor belt 1 for transporting boxed meals. Numerous positioning elements 3 are installed at intervals on the tracked conveyor belt 1. Each positioning element 3 is supported by an elastic element 4, and an iron support element 18, which is vertically adjustable and has a C-shaped limiting element 17 internally located within it. The boxed meals are placed at an angle between adjacent positioning elements 3, with the end of the meal abutting the front end of the rear positioning element 3 and the bottom surface abutting the iron support element 18 installed above the front positioning element 3. This support method isolates and secures the boxed meals. Compared to simply using fixed partitions for isolation, the energization of an electromagnet 14 controls the iron support element 18. The meal box is positioned so that the center of gravity of the meal box changes by changing the position of the iron support 18. The meal box is then fed into the receiving box 5 by rotating in an arc with the abutting end of the meal box as the center. This ensures that the back of the meal box can be oriented onto the receiving box, and the front of the meal box is facing up, which is conducive to subsequent detection. The feeding is achieved by using an electromagnet 14 to attract and move the corresponding iron support 18 downward. Compared with the push-type feeding, this utility model can improve the accuracy and convenience of feeding while ensuring smooth delivery of the meal box. Moreover, the single directional driving feeding is more time-saving and labor-saving, which improves the practical effect of this utility model.
[0051] The tracked cargo channel 1 includes a cargo channel body 101 and a conveyor belt 102 sleeved around the cargo channel body 101. The front and rear ends of the cargo channel body 101 are respectively rotatably mounted with a driven shaft and a driving shaft, and the driving shaft is fixedly connected to the output shaft end of the drive motor 2. The positioning member 3 is fixedly mounted on the surface of the conveyor belt 102 by adhesive bonding.
[0052] The control mechanism includes an electromagnet 14 fixedly installed on the rear side of the discharge end of the tracked cargo channel 1, a ranging tag 15 fixedly installed on the surface of the driven shaft at the discharge end of the tracked cargo channel 1, and a photoelectric sensor 16 adapted to the ranging tag 15. The photoelectric sensor 16 and the electromagnet 14 are both electrically connected to the control system. When the receiving box 5 moves to the corresponding discharge end of the tracked cargo channel 1, the drive motor 2 is activated and drives the tracked cargo channel 1 to rotate in the forward direction. When the number of times the photoelectric sensor 16 senses the ranging tag 15 is n, where n≥2, the drive motor 2 stops, and the electromagnet 14 is energized to attract the iron support 18 and move it down into the limiting member 17 to form a clearance, and the elastic member 4 is compressed.
[0053] This invention utilizes the adjustment setting of the number of rotations of the driven shaft of the conveyor belt 102 when the positioning component 3 is displaced by one station. The photoelectric sensor 16 senses the number of times the ranging label 15 installed on the driven shaft is moved, and the displacement distance of the positioning component 3 is precisely controlled. This ensures that the electromagnet 14 is placed directly below the iron support component 18. When the electromagnet 14 is energized, it drives the iron support component 18 to move down to make room for the lunch boxes to be unloaded. The lunch boxes are supported by a single force and driven to be unloaded by a single drive, without affecting each other. Moreover, no matter how many lunch boxes are placed on the conveyor belt 1, the speed of the drive motor 2 does not affect the unloading, thus making the unloading more labor-saving and precise.
[0054] The two sides of the tracked cargo lane 1 are respectively provided with corresponding partitions 12 at intervals.
[0055] Example 2
[0056] refer to Figure 3 The difference between this embodiment and embodiment one is that: a corresponding spare box 13 is fixedly connected to the top of the receiving box 5, and a corresponding detection mechanism is also installed below the top of the spare box 13. When the pressure sensor 9 inside the receiving box 5 detects that the pressure value is less than the set value F1 or greater than the set value F2, an alarm is issued, and the receiving box 5 moves down to the spare box 13 and is placed at the front end of the track conveyor 1 for re-discharging.
[0057] This invention features a spare box 13 with the same structure above the receiving box 5, and an identical detection mechanism installed inside the spare box 13. When the receiving box 5 receives a boxed meal with a leaking or bulging bag, it can promptly and quickly provide the customer with a new boxed meal. A dedicated temporary storage area for defective boxed meals is also provided. The bottom of the receiving box 5 is hinged and can be rotated by a lifting cylinder, thereby raising the lower side plate to transfer the defective boxed meals to the temporary storage area for processing by staff. This ensures the receiving mechanism can continue to be used. The closing plate of the temporary storage area is installed using a torsion spring and a rotating shaft, and is equipped with a corresponding sealing strip to ensure the temporary storage area is normally closed and effectively isolated from the storage area, preventing defective boxed meals from adversely affecting normal boxed meals or the boxed meal machine, thus improving the user experience of this invention.
[0058] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.
[0059] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
