Description

Technical Field

[0001] This invention relates to the field of weighing and settlement technology, specifically to an integrated weighing and settlement machine for canteens. Background Technology

[0002] With the development and widespread application of smart technology, unmanned weighing and payment canteens have emerged. The main method is for diners to place their food on the weighing and payment equipment and then complete the payment by scanning a QR code. This model reduces the labor costs of canteens.

[0003] Currently, there are many devices used for weighing and settlement, including a canteen group meal weighing, settlement, and barcode scanning integrated machine disclosed in Chinese patent publication number CN216772542U. This machine includes a base shell with two supports along one side of its width. A display screen is located on the top of the two supports. A sensor is located inside the base shell, and a fixing block is located on the bottom plate of the base shell. A claw-shaped plate is located on the sensor, and a sheet metal bending base is located on the outer wall of the claw-shaped plate. A glass weighing platform is located on the claw-shaped plate. Another example is a weighing, settlement, and barcode scanning integrated machine disclosed in Chinese patent publication number CN218497579U. This machine includes a base with a glass weighing platform at the top and a food placement platform at the top of the glass weighing platform. Support rods are fixedly connected to the left and right sides of the rear surface of the base. An integrated computer is fixedly connected to the top of the two sets of support rods, and a cleaning component for controlling the rotation of the food placement platform is located at the bottom of the two sets of support rods.

[0004] Neither the devices disclosed in the aforementioned patents nor other types of equipment can effectively handle meal payment. This is because, in addition to ingredients priced by weight, canteens also offer meals priced by portion. Diners select their ingredients, place them on the weighing and payment equipment to determine their weight, and then the chef prepares the food. However, when diners purchase pre-cooked meals, such as various stir-fries, payment must be made by portion, which cannot be completed using weighing and payment equipment. Therefore, existing weighing and payment equipment is of limited practicality. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated weighing and settlement machine for canteens, aiming to improve the problem of low practicality of current equipment used for weighing and settling meals.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0035] Example 1

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9As shown, a canteen weighing and settlement integrated machine includes a base shell 1, a support platform 5, a collection bin 4, an integrated computer 2, and an industrial camera 3. The upper end of the base shell 1 is open, and notches 15 are provided at the upper ends of both the left and right side walls. A vertical pipe 11 is provided at the rear end, and a weighing sensor 14 is provided at the bottom inside the base shell 1. The support platform 5 is vertically positioned above the base shell 1, with notches 15 extending through both ends. The support platform 5 includes a transmission belt 6 and a support frame 7. The support frame 7 includes two support rollers 71 and two support plates 76. The two parallel support rollers 71 are positioned between the two support plates 76 and on the outside of the base shell 1. A claw-shaped plate 761, smaller than the size of the base shell 1, is bolted to the bottom of the two support plates 76 and connected to the weighing sensor 14. The transmission belt 6 is sleeved on the two support rollers 71. One of the support rollers 71 is connected to the motor, while the claw plate 761 is located below the transmission belt 6. Under the operation of the motor, the support roller 71 rotates, thereby driving the transmission belt 6 to rotate. This forces food left on the transmission belt 6 to move relative to the bottom shell 1. When the food moves to the end of the transmission belt 6, it falls into the collection chamber 4 under the action of gravity. The collection chamber 4 is located below the end of the transmission belt 6. This arrangement effectively removes food from the transmission belt 6, preventing the presence of leftover food from increasing the cost for the next diner. A vertical plate 24 is located at the rear of the integrated computer 2. An insert plate 25 is located at the lower end of the vertical plate 24. The lower end of the insert plate 25 is inserted into the vertical tube 11. Bolts are threaded through the side wall of the vertical tube 11, with the ends of the bolts pressing against the insert plate 25. This arrangement allows for adjustment of the height of the integrated computer 2 relative to the bottom shell 1 as needed, providing support for expanding the practicality of the device. A horizontal plate 31 is positioned above the industrial camera 3. A frame 32 is fixedly mounted at the end of the horizontal plate 31, fitting onto the insert plate 25 and connected to the vertical pipe 11 via connecting bolts. The industrial camera 3 and the weighing sensor 14 are electrically connected to the processor within the integrated computer 2, which stores multiple photos of cooked food. When a diner places their food on the conveyor belt 6, the industrial camera 3 first captures a photo of the food and transmits this information to the processor. The processor then determines whether the food on the conveyor belt 6 is sold by portion or by weight. If it is determined to be sold by portion, the cost is displayed on the integrated computer 2. If not, the processor obtains the weighing information from the weighing sensor 14, calculates the cost by multiplying the unit price and weight, and displays this cost on the integrated computer 2. Once the cost is displayed on the integrated computer 2, the diner can scan the payment QR code and pay using the scanning lens of the integrated computer 2. After payment is completed, the processor controls the motor to drive the transmission belt 6 to rotate, removing any food left on the transmission belt 6.

[0037] like Figure 2As shown, in order to facilitate quick assembly and disassembly of the claw plate 761 and the support plate 76 as needed, through holes 13 are provided on the front and rear end faces of the bottom shell 1. The through holes 13 are directly opposite the bolts, and the diameter of the holes is larger than the diameter of the bolts, so that personnel can hold disassembly tools and insert them into the through holes 13 to rotate the bolts, thereby realizing the assembly and disassembly of the claw plate 761 and the support plate 76.

[0038] like Figure 3 , Figure 4 As shown, in order to adjust the tilt angle of the integrated computer 2 according to usage needs and facilitate diners to view dining information, a fixed plate 21 is hinged to the upper rear side of the integrated computer 2, and a limiting plate 22 is hinged to the lower middle rear side. Multiple limiting grooves 23 are provided on the lower side of the limiting plate 22, and the multiple limiting grooves 23 are evenly distributed along the arc length direction of the limiting plate 22. At the same time, a through hole 26 is provided on the vertical plate 24, and a limiting shaft 27 and a pressure roller 28 are passed through the through hole 26. A bracket is provided on the pressure roller 28, and a top rod is fixedly provided at the upper end of the bracket. A spring is sleeved on the top rod, and the top rod is inserted into the tube body. The tube body is connected to the top wall of the through hole 26. At the same time, the spring is in a compressed state, and its two ends press against the tube body and the bracket respectively. Under the action of the spring, the pressure roller 28 tends to move downward and press against the limiting plate 22. When assembling the all-in-one computer 2, a fixing plate 21 is bolted to the upper end of the vertical plate 24. A limiting plate 22 is installed through a through hole 26, and a limiting shaft 27 is installed through a limiting groove 23. A pressure roller 28 presses against the upper side of the limiting plate 22, thus the limiting plate 22 can be stably placed relative to the vertical plate 24. When it is necessary to adjust the tilt angle of the all-in-one computer 2, the user holds the free end of the limiting plate 22 and moves it. At the same time, the pressure roller 28 rises. When the limiting shaft 27 disengages from the limiting groove 23, the all-in-one computer 2 is pushed to move, thereby adjusting its tilt angle. After adjusting the tilt angle of the all-in-one computer 2, the limiting shaft 27 is then controlled to pass through another limiting groove 23 to maintain the stable placement of the all-in-one computer 2.

[0039] like Figure 2 , Figure 6 As shown, in order to limit the position of the collection chamber 4 and prevent it from moving and causing food to spill, a groove 41 is provided on the lower side of the collection chamber 4. A connecting plate 43 is provided through the groove 41. A baffle 44 and a retaining plate 42 are provided on the connecting plate 43. The two baffles 44 are located on both sides of the collection chamber 4, and the side walls close to each other are provided with rubber layers. The rubber layers deform to fit the side walls of the collection chamber 4. The retaining plate 42 is located at the end of the connecting plate 43 opposite to the edge of the bottom shell 1, and its upper end is inserted into the retaining groove 12 of the bottom shell 1. The upper end of the retaining plate 42 and the cross section of the retaining groove 12 are both designed with concave and convex structures. Therefore, the connecting plate 43 can be stably placed relative to the bottom shell 1, thereby controlling the collection chamber 4 to be stably placed under the transmission belt 6.

[0040] like Figure 10As shown, in order to completely cover the support frame 7 with the transmission belt 6, both the support roller 71 and the support plate 76 are located inside the transmission belt 6, which improves the aesthetics of the device. However, in order to restrict the movement of the transmission belt 6, end posts are provided at both ends of the support roller 71. The end face of the end post is provided with a polygonal groove 78, and a baffle 77 is provided on the side of the end post. A polygonal post 79 is provided on the baffle 77. The polygonal post 79 is bolted and can be detachably inserted into the polygonal groove 78. The baffle 77 is located outside the transmission belt 6, and its diameter is greater than or equal to the height of the transmission belt 6. Therefore, under the premise that the baffle 77 rotates synchronously with the transmission belt 6, the position of the transmission belt 6 is restricted, preventing the transmission belt 6 from deviating and affecting the use of the device.

[0041] like Figure 8 , Figure 9 As shown, to stably support the food, a support plate 72 is provided on the inner side of the transmission belt 6. The upper side of the support plate 72 slides in contact with the side wall of the transmission belt 6, thus supporting the transmission belt 6 to be placed stably and horizontally, providing support for supporting the food and weighing. To adjust the height of the support plate 72 during assembly, a connector plate 73 is provided on the lower edge of the support plate 72. The side walls of the two support plates 76 that are close to each other are provided with connector grooves 74. The lower end of the connector groove 74 is closed and an adjusting screw 75 is provided through it. The lower ends of the two adjusting screws 75 can be connected to the transmission ring belt. The lower end of the connector plate 73 extends into the connector groove 74, and the upper end of the adjusting screw 75 is threaded into the connector plate 73. By rotating one adjusting screw 75, the two adjusting screws 75 can be controlled to rotate synchronously, adjusting the height of the support plate 72, which provides convenience for replacement and maintenance.

[0042] like Figure 7 , Figure 11 , Figure 12As shown, in order to remove liquid from the conveyor belt 6, a scraping mechanism 8 is provided at the lower end of the conveyor belt 6. The scraping mechanism 8 includes two parallel main plates 81 and two support plates 83. The two main plates 81 are inclined and each has a rubber plate 82 at its upper end. The rubber plate 82 contacts the lower side of the conveyor belt 6. During the rotation of the conveyor belt 6, the rubber plate 82 scrapes off the liquid adhering to the conveyor belt 6, and the scraped liquid slides down along the inclined rubber plate 82 and main plates 81 into the collection chamber 4. This minimizes the impact of food and liquid left by the previous diner on the meal cost of the next diner and avoids the next diner's mood being affected by the dirty conveyor belt 6. To enable the detachable configuration of the main board 81 and the support plate 83, an end plate 84 is provided on the side of the two support plates 83 that are close to each other. The end plate 84 is provided with a slanted groove 85, and the end of the main board 81 extends into the slanted groove 85. The side walls of the two end plates 84 that are far apart from each other are provided with a mounting groove 86. The upper end of the support plate 83 is connected to the support plate 76 by bolts, and the lower end extends into the mounting groove 86 by bolts. Therefore, while ensuring the stable placement of the main board 81, it provides convenience for quick assembly and disassembly.

[0043] Example 2

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9As shown, a canteen weighing and settlement integrated machine includes a base shell 1, a support platform 5, a collection bin 4, an integrated computer 2, and an industrial camera 3. The upper end of the base shell 1 is open, and notches 15 are provided at the upper ends of both the left and right side walls. A vertical pipe 11 is provided at the rear end, and a weighing sensor 14 is provided at the bottom inside the base shell 1. The support platform 5 is vertically positioned above the base shell 1, with notches 15 extending through both ends. The support platform 5 includes a transmission belt 6 and a support frame 7. The support frame 7 includes two support rollers 71 and two support plates 76. The two parallel support rollers 71 are positioned between the two support plates 76 and on the outside of the base shell 1. A claw-shaped plate 761, smaller than the size of the base shell 1, is bolted to the bottom of the two support plates 76 and connected to the weighing sensor 14. The transmission belt 6 is sleeved on the two support rollers 71. One of the support rollers 71 is connected to the motor, while the claw plate 761 is located below the transmission belt 6. Under the operation of the motor, the support roller 71 rotates, thereby driving the transmission belt 6 to rotate. This forces food left on the transmission belt 6 to move relative to the bottom shell 1. When the food moves to the end of the transmission belt 6, it falls into the collection chamber 4 under the action of gravity. The collection chamber 4 is located below the end of the transmission belt 6. This arrangement effectively removes food from the transmission belt 6, preventing the presence of leftover food from increasing the cost for the next diner. A vertical plate 24 is located at the rear of the integrated computer 2. An insert plate 25 is located at the lower end of the vertical plate 24. The lower end of the insert plate 25 is inserted into the vertical tube 11. Bolts are threaded through the side wall of the vertical tube 11, with the ends of the bolts pressing against the insert plate 25. This arrangement allows for adjustment of the height of the integrated computer 2 relative to the bottom shell 1 as needed, providing support for expanding the practicality of the device. A horizontal plate 31 is positioned above the industrial camera 3. A frame 32 is fixedly mounted at the end of the horizontal plate 31, fitting onto the insert plate 25 and connected to the vertical pipe 11 via connecting bolts. The industrial camera 3 and the weighing sensor 14 are electrically connected to the processor within the integrated computer 2, which stores multiple photos of cooked food. When a diner places their food on the conveyor belt 6, the industrial camera 3 first captures a photo of the food and transmits this information to the processor. The processor then determines whether the food on the conveyor belt 6 is sold by portion or by weight. If it is determined to be sold by portion, the cost is displayed on the integrated computer 2. If not, the processor obtains the weighing information from the weighing sensor 14, calculates the cost by multiplying the unit price and weight, and displays this cost on the integrated computer 2. Once the cost is displayed on the integrated computer 2, the diner can scan the payment QR code and pay using the scanning lens of the integrated computer 2. After payment is completed, the processor controls the motor to drive the transmission belt 6 to rotate, removing any food left on the transmission belt 6.

[0045] like Figure 2As shown, in order to facilitate quick assembly and disassembly of the claw plate 761 and the support plate 76 as needed, through holes 13 are provided on the front and rear end faces of the bottom shell 1. The through holes 13 are directly opposite the bolts, and the diameter of the holes is larger than the diameter of the bolts, so that personnel can hold disassembly tools and insert them into the through holes 13 to rotate the bolts, thereby realizing the assembly and disassembly of the claw plate 761 and the support plate 76.

[0046] like Figure 3 , Figure 4 As shown, in order to adjust the tilt angle of the integrated computer 2 according to usage needs and facilitate diners to view dining information, a fixed plate 21 is hinged to the upper rear side of the integrated computer 2, and a limiting plate 22 is hinged to the lower middle rear side. Multiple limiting grooves 23 are provided on the lower side of the limiting plate 22, and the multiple limiting grooves 23 are evenly distributed along the arc length direction of the limiting plate 22. At the same time, a through hole 26 is provided on the vertical plate 24, and a limiting shaft 27 and a pressure roller 28 are passed through the through hole 26. A bracket is provided on the pressure roller 28, and a top rod is fixedly provided at the upper end of the bracket. A spring is sleeved on the top rod, and the top rod is inserted into the tube body. The tube body is connected to the top wall of the through hole 26. At the same time, the spring is in a compressed state, and its two ends press against the tube body and the bracket respectively. Under the action of the spring, the pressure roller 28 tends to move downward and press against the limiting plate 22. When assembling the all-in-one computer 2, a fixing plate 21 is bolted to the upper end of the vertical plate 24. A limiting plate 22 is installed through a through hole 26, and a limiting shaft 27 is installed through a limiting groove 23. A pressure roller 28 presses against the upper side of the limiting plate 22, thus the limiting plate 22 can be stably placed relative to the vertical plate 24. When it is necessary to adjust the tilt angle of the all-in-one computer 2, the user holds the free end of the limiting plate 22 and moves it. At the same time, the pressure roller 28 rises. When the limiting shaft 27 disengages from the limiting groove 23, the all-in-one computer 2 is pushed to move, thereby adjusting its tilt angle. After adjusting the tilt angle of the all-in-one computer 2, the limiting shaft 27 is then controlled to pass through another limiting groove 23 to maintain the stable placement of the all-in-one computer 2.

[0047] like Figure 2 , Figure 6 As shown, in order to limit the position of the collection chamber 4 and prevent it from moving and causing food to spill, a groove 41 is provided on the lower side of the collection chamber 4. A connecting plate 43 is provided through the groove 41. A baffle 44 and a retaining plate 42 are provided on the connecting plate 43. The two baffles 44 are located on both sides of the collection chamber 4, and the side walls close to each other are provided with rubber layers. The rubber layers deform to fit the side walls of the collection chamber 4. The retaining plate 42 is located at the end of the connecting plate 43 opposite to the edge of the bottom shell 1, and its upper end is inserted into the retaining groove 12 of the bottom shell 1. The upper end of the retaining plate 42 and the cross section of the retaining groove 12 are both designed with concave and convex structures. Therefore, the connecting plate 43 can be stably placed relative to the bottom shell 1, thereby controlling the collection chamber 4 to be stably placed under the transmission belt 6.

[0048] like Figure 10As shown, in order to completely cover the support frame 7 with the transmission belt 6, both the support roller 71 and the support plate 76 are located inside the transmission belt 6, which improves the aesthetics of the device. However, in order to restrict the movement of the transmission belt 6, end posts are provided at both ends of the support roller 71. The end face of the end post is provided with a polygonal groove 78, and a baffle 77 is provided on the side of the end post. A polygonal post 79 is provided on the baffle 77. The polygonal post 79 is bolted and can be detachably inserted into the polygonal groove 78. The baffle 77 is located outside the transmission belt 6, and its diameter is greater than or equal to the height of the transmission belt 6. Therefore, under the premise that the baffle 77 rotates synchronously with the transmission belt 6, the position of the transmission belt 6 is restricted, preventing the transmission belt 6 from deviating and affecting the use of the device.

[0049] like Figure 8 , Figure 9 As shown, to stably support the food, a support plate 72 is provided on the inner side of the transmission belt 6. The upper side of the support plate 72 slides in contact with the side wall of the transmission belt 6, thus supporting the transmission belt 6 to be placed stably and horizontally, providing support for supporting the food and weighing. To adjust the height of the support plate 72 during assembly, a connector plate 73 is provided on the lower edge of the support plate 72. The side walls of the two support plates 76 that are close to each other are provided with connector grooves 74. The lower end of the connector groove 74 is closed and an adjusting screw 75 is provided through it. The lower ends of the two adjusting screws 75 can be connected to the transmission ring belt. The lower end of the connector plate 73 extends into the connector groove 74, and the upper end of the adjusting screw 75 is threaded into the connector plate 73. By rotating one adjusting screw 75, the two adjusting screws 75 can be controlled to rotate synchronously, adjusting the height of the support plate 72, which provides convenience for replacement and maintenance.

[0050] like Figure 7 , Figure 11 , Figure 12As shown, in order to remove liquid from the conveyor belt 6, a scraping mechanism 8 is provided at the lower end of the conveyor belt 6. The scraping mechanism 8 includes two parallel main plates 81 and two support plates 83. The two main plates 81 are inclined and each has a rubber plate 82 at its upper end. The rubber plate 82 contacts the lower side of the conveyor belt 6. During the rotation of the conveyor belt 6, the rubber plate 82 scrapes off the liquid adhering to the conveyor belt 6, and the scraped liquid slides down along the inclined rubber plate 82 and main plates 81 into the collection chamber 4. This minimizes the impact of food and liquid left by the previous diner on the meal cost of the next diner and avoids the next diner's mood being affected by the dirty conveyor belt 6. To enable the detachable configuration of the main board 81 and the support plate 83, an end plate 84 is provided on the side of the two support plates 83 that are close to each other. The end plate 84 is provided with a slanted groove 85, and the end of the main board 81 extends into the slanted groove 85. The side walls of the two end plates 84 that are far apart from each other are provided with a mounting groove 86. The upper end of the support plate 83 is connected to the support plate 76 by bolts, and the lower end extends into the mounting groove 86 by bolts. Therefore, while ensuring the stable placement of the main board 81, it provides convenience for quick assembly and disassembly.

[0051] like Figure 13 As shown, in order to adjust the position of the rubber plate 82 to fit the transmission belt 6, the support plate 83 includes an upper plate 87 and a lower plate 88. The lower end face of the upper plate 87 is provided with a slot, and a bolt is provided through the lower side via a bearing connection. The upper end face of the lower plate 88 is fixedly provided with a plug 89, and a nut is fixedly provided on the upper side. The plug 89 is inserted into the slot, and the lower end thread of the bolt passes through the nut. By rotating the bolt, the relative position of the upper plate 87 and the lower plate 88 can be adjusted, thereby adjusting the height of the main plate 81 and forcing the rubber plate 82 to fit and contact the transmission belt 6.
