Description

Technical Field

[0001] The invention relates to the technical field of heating type lunch box machines, in particular to a highly adaptable heating type lunch box machine. Background Art

[0002] Vending machines are a sales model that is not limited by time and location, saves manpower and facilitates transactions. Common vending machines are divided into four types: beverage vending machines, food vending machines, comprehensive vending machines, and cosmetics vending machines. With the accelerated pace of life, vending machines that sell boxed lunches, also commonly known as boxed lunch machines, are gradually being widely used, allowing general staff, especially white-collar workers, to quickly finish their meals in a shorter lunch time.

[0003] Lunch box machines are different from vending machines for beverages and general packaged foods. They have problems with heating and heat preservation, shelf life, and damage and deterioration of lunch boxes. Existing vending machines mainly include smart vending machines, serpentine or curved aisle vending machines, spring drawer vending machines, and in-line stacking vending machines. Among them, smart vending machines can open the cabinet door by scanning a code to select items at will, but for items such as lunch boxes that need to be kept at a constant temperature and have a short shelf life, repeated opening and closing of the cabinet door will cause the temperature inside the cabinet to drop below the requirements, and the product storage and sales requirements cannot be guaranteed. In addition, the repeated opening and closing of the door will cause the product to be in a variable temperature environment, which can easily reduce its shelf life. The aisles of serpentine or curved aisle vending machines are curved metal cavities, which are not suitable for larger lunch boxes. In addition, the delivery method is to discharge them one by one like a magazine, relying on the product's own gravity to slide down and deliver them from top to bottom. The stacking of products in the aisles is not conducive to the dispersion of heat, and the constant temperature control of all lunch boxes cannot be guaranteed. In addition, the structure is complex, the scope of application is small, and the equipment price is high. The spring drawer vending machine uses a spring spiral aisle to push beverages or food forward. This spiral aisle cannot push rectangular lunch boxes, and the direct drop of materials from top to bottom can easily cause the film-packaged lunch boxes to break and leak due to impact. The items in the inline stacking vending machine are stacked together, which can easily cause the lunch boxes around to heat up quickly, while the lunch boxes in the middle area heat up slowly and unevenly, and it cannot ensure that all lunch boxes are in the same constant temperature state, which can easily lead to different heating quality of lunch boxes. Therefore, the existing vending machines are only suitable for packaged foods such as beverages and snacks. Even if a heating system is added, it cannot fully meet the requirements of automatic lunch box vending, which is very tricky. Therefore, it is very important to change the storage and discharging structure of lunch boxes.

[0004] At present, the method of pushing materials with crawler cargo lanes combined with push plates is more suitable for storing and unloading lunch boxes with cubic or cylindrical structures and is put into use. However, due to the different number of stacked lunch boxes, the required thrust is different, so the thrust cannot be accurately set, and thus the unloading cannot be accurately controlled. In addition, the stacking also has the problem of uneven heating. Setting corresponding partitions between each lunch box will inhibit the pushing action, so it cannot be actually solved.

[0005] Therefore, a device is designed that, on the basis of ensuring smooth delivery of lunch boxes, stores and drives the lunch boxes to move through a crawler cargo channel, and then combines a support mechanism for inclined, isolated storage of lunch boxes, and utilizes the lifting characteristics of the support mechanism to control the stable support and single directional discharge of the lunch boxes, and can isolate adjacent lunch boxes to avoid stacking and fitting of lunch boxes and affecting the uniformity of heating to ensure the shelf life; furthermore, a highly adaptable heating lunch box machine can be used to determine the leakage and bulging of lunch boxes through pressure measurement to ensure the sales quality and reduce after-sales problems.

[0025] Advantages of the present invention:

[0026] 1) The present invention adopts a crawler cargo track for conveying lunch boxes, and a plurality of positioning members are installed at intervals on the crawler cargo track, and an iron support member that can be lifted up and down and is internally arranged in a limiting member is arranged on the positioning member through an elastic member support; the lunch box is placed obliquely between two adjacent positioning members to form a spacing isolation, and the end of the lunch box abuts against the front end of the rear positioning member, and the bottom of the lunch box abuts against the iron support member installed above the front positioning member, and the lunch box is isolated and fixed by supporting. Compared with the isolation method of simply isolating by a fixed partition, the setting position of the iron support member can be controlled by whether the electromagnet is energized or not. The position change of the iron support is utilized to change the center of gravity of the lunch box, and then the lunch box is unloaded by relying on the offset of its center of gravity. The lunch box is rotated in an arc with the abutting end as the center to unload the lunch into the receiving box, thereby ensuring that the back of the lunch box can be directed onto the receiving box, with the front of the lunch box facing upward, which is beneficial to subsequent detection actions. Unloading can be achieved by energizing and adsorbing the electromagnet to drive the corresponding iron support to move downward. Compared with push-type unloading, the present invention can improve the accuracy and convenience of unloading on the basis of ensuring smooth delivery of the lunch box, and single directional drive unloading saves time and effort, thereby improving the practical effect of the present invention.

[0027] 2) The present invention utilizes the adjustment setting between the number of revolutions of the driven shaft of the conveyor belt when the positioning member is displaced by one station, and uses the photoelectric sensor to sense the number of times the distance measuring label installed on the driven shaft is sensed, so as to accurately control the displacement distance of the positioning member, thereby ensuring that the electromagnet is placed directly below the iron support member, and the iron support member is driven downward by the electromagnet to make way for lunch box unloading. The lunch boxes are unloaded through a single force support and a single drive, and they do not affect each other. No matter how many lunch boxes are placed on the crawler cargo lane, the speed of the drive motor will not affect the unloading, thereby making the drive unloading more labor-saving and accurate.

[0028] 3) The present invention drives the receiving box body to move left and right by means of gear transmission, and drives the receiving box body to move up and down by means of screw transmission, so that the receiving box body can stably move between the front end of each crawler cargo channel and the meal pick-up port and deliver the lunch box. Compared with the method of directly dropping the material by transmission pushing, the present invention can effectively shorten the distance of the lunch box falling through the receiving box body, thereby protecting the lunch box, and preventing the bag from leaking or impact deformation due to falling from a high distance, which affects sales; and a corresponding detection mechanism is arranged below the top of the receiving box body, and the small cylinder sets the extension stroke S of the piston rod according to the different pressures of the lunch box pressing. 1 The pressure sensor installed at the end of the piston rod detects the pressure value at the set value F 1 -F 2 It can be confirmed that there is no leakage in the lunch box (the leakage pressure value is less than F 1 ), or no expansion bag (the expansion bag pressure value is greater than F 2), thereby ensuring that the lunch boxes delivered out are in good condition, thereby ensuring the quality of the lunch boxes sold and reducing after-sales problems.

[0029] 4) The present invention installs a corresponding isolation plate under the storage area, uses an electric heater to heat and then uses a blower to disperse the hot air, so that the hot air circulates, and the positioning parts and iron support parts installed on the crawler cargo path are used to place the lunch boxes at intervals to avoid close stacking, effectively promoting the circulation and dispersion of hot air around the lunch boxes, so that the lunch boxes are heated more evenly, ensuring that the lunch boxes in the lunch box machine are all heated, and the heating speed and heating time are similar, effectively eliminating the phenomenon that the traditional vending machine heats quickly around and slowly in the middle.

[0030] 5) The lower side plate of the receiving box body of the present invention is inclined downward from the meal inlet to the meal outlet, and forms a V-shaped material receiving groove. When the lunch box is unloaded from the crawler cargo track to the receiving box body, the inclined surface and gravity are used to promote the lunch box to move into the receiving box body and leave the crawler cargo track, thereby improving the smoothness of material unloading and receiving; and promoting the lunch box to move downward along the inclined surface to guide the material to the meal pickup port, so that people can pick up the meal.

[0031] 6) In the present invention, a corresponding closing plate is installed at the meal outlet of the receiving box body, which is driven to rotate by a driving motor or to move up and down by a lifting cylinder. The closing plate can not only block the meal outlet when the receiving box body receives materials, effectively preventing the meal box from falling from the meal outlet and protecting the meal box; but also can block the meal outlet when the receiving box body is reset to the meal outlet, without the need to additionally provide a corresponding anti-theft mechanism at the meal outlet.

[0032] 7) The present invention sets a spare box body with the same structure above the receiving box body, and installs the same detection mechanism in the spare box body. When the receiving box body receives a lunch box with a leaking bag or a bulging bag, the lunch box product can be promptly and quickly re-provided to the customer; and a temporary storage area for defective lunch boxes is specially set, and the bottom of the receiving box body is set to be hinged, which can be driven to rotate by a lifting cylinder, and then the defective lunch box is transferred to the temporary storage area by lifting the lower side plate for temporary storage to be processed by the staff, and it is ensured that the material receiving mechanism can continue to be used. The closing plate of the temporary storage area is installed in a manner of torsion spring and rotating shaft, and a corresponding sealing strip is provided to ensure that the temporary storage area is normally closed and effectively isolated from the storage area, so as to prevent the defective lunch boxes from having an adverse effect on the normal lunch boxes or lunch box machines, thereby improving the user experience of the present invention.

[0047] The regulating mechanism cooperates with the elastic member 9 to control the upward and downward movement of the iron support member 10, and comprises an electromagnet 12 fixedly mounted on the rear side of the discharge end of the crawler cargo channel 6, a distance measuring tag 13 fixedly mounted on the surface of the driven shaft of the discharge end of the crawler cargo channel 6, and a photoelectric sensor 14 adapted to the distance measuring tag 13, wherein the photoelectric sensor 14 and the electromagnet 12 are both electrically connected to the control system; after the receiving box 11 is regulated by the control system to move to the corresponding discharge end of the crawler cargo channel 6, the drive motor 5 is activated and drives the crawler cargo channel 6 to transmit forwardly, and when the photoelectric sensor 14 senses the distance measuring tag 13 for n times, where n≥2, the drive motor 5 stops, and the electromagnet 12 is energized to adsorb the iron support member 10 to move downward and place it in the limit member 8 to make way, and the elastic member 9 is compressed;

[0048] The detection mechanism includes a pressing plate 16 installed below the top of the receiving box body 11 and driven up and down by a corresponding small cylinder 15.

[0050] The present invention adopts a crawler cargo lane 6 for conveying boxed lunches, and a plurality of positioning members 7 are installed at intervals on the crawler cargo lane 6. An iron support member 10 which can be lifted up and down and is internally arranged in a limiting member 8 is supported by an elastic member 9 on the positioning member 7; the boxed lunch is placed obliquely between two adjacent positioning members 7 to form a spacing isolation, and the end of the boxed lunch abuts against the front end of the rear positioning member 7, and the bottom surface of the boxed lunch abuts against the iron support member 10 installed above the front positioning member 7. The boxed lunch is isolated and fixed by supporting.

Compared with push-type discharge, the present invention can improve the accuracy and convenience of discharge on the basis of ensuring smooth delivery of the lunch box, and single directional drive discharge is more time-saving and labor-saving, thereby improving the practical effect of the present invention.

[0051] The present invention utilizes the adjustment setting between the number of revolutions of the driven shaft of the conveyor belt 602 when the positioning member is displaced by one station, and senses the number of times the distance measuring label 13 installed on the driven shaft through the photoelectric sensor 14, so as to accurately control the displacement distance of the positioning member 7, thereby ensuring that the electromagnet 12 is placed directly below the iron support member 10, and the iron support member 10 is driven downward by the electromagnet 12 to make way for lunch box unloading. The lunch boxes are unloaded through a single force support and a single drive, and they do not affect each other. No matter how many lunch boxes are placed on the crawler cargo lane 6, the driving speed of the drive motor 5 will not affect the unloading, thereby making the driving unloading more labor-saving and accurate.

[0052] The present invention drives the receiving box body 11 to move left and right by means of gear transmission, and drives the receiving box body 11 to move up and down by means of screw transmission, so that the receiving box body 11 can stably move between the front end of each crawler cargo lane 6 and the meal taking port 2 and deliver the lunch box. Compared with the method of directly dropping the material by transmission pushing, the present invention can effectively shorten the distance of the lunch box falling by means of the receiving box body 11, thereby protecting the lunch box, and preventing the bag from breaking and leaking or impact deformation due to falling from a high distance, which affects sales; and a corresponding detection mechanism is arranged below the top of the receiving box body 11, and the small cylinder 15 sets the extension stroke S of the piston rod according to the pressure of different lunch box pressing. 1 The pressure sensor 18 installed at the end of the piston rod detects the pressure value at the set value F 1 -F 2 It can be confirmed that there is no leakage in the lunch box (the leakage pressure value is less than F 1 ), or no expansion bag (the expansion bag pressure value is greater than F 2 ), thereby ensuring that the lunch boxes delivered out are in good condition, thereby ensuring the quality of the lunch boxes sold and reducing after-sales problems.

[0053] The present invention installs a corresponding isolation plate 19 under the storage area, uses an electric heater 20 to heat and then uses a blower 21 to disperse the hot air, so that the hot air circulates, and the positioning parts 7 and iron support parts 10 installed on the crawler cargo lane 6 are used to place the lunch boxes at intervals to avoid close stacking, effectively promoting the circulation and dispersion of hot air around the lunch boxes, so that the lunch boxes are heated more evenly, ensuring that the lunch boxes in the lunch box machine are all heated, and the heating speed and heating time are similar, effectively preventing the phenomenon that the traditional vending machines heat quickly around and slowly in the middle.
