Material conveying system with cleaning device

Abstract

A material conveying system with a cleaning device includes a material silo with at least one feeding outlet. A conveying device receives materials from the feeding outlet and outputs the materials outward through the dispensing outlet of the conveying device. A baffle is installed between the material silo and the conveying device. The baffle has at least one set of holes and fits into at least one feeding outlet through the at least one set of holes, thereby separating the material silo from the conveying device. A cleaning device is installed in conjunction with the conveying device. A water tank is installed directly below the baffle and the conveying device. A water pump draws liquid from the water tank and transports it to the conveying device for cleaning. The cleaned liquid flows downward into the water tank and is then drawn back to the conveying device by the water pump. Therefore, cleaning is very convenient.

Description

[Technical Field]

[0001] This invention relates to a material conveying system; in particular, it refers to a material conveying system with a cleaning device. [Previous Technology]

[0002] Current methods for cooking large quantities of food for diners mainly involve using larger pots than those used in typical households to prepare more dishes in the same amount of time, or hiring more chefs to cook more dishes at the same time. However, to produce delicious dishes using larger pots, the chefs need experience and skills in cooking large batches, and hiring more chefs greatly increases the difficulty of hiring manpower and allocating staff during cooking.

[0003] To solve the aforementioned problem of manual cooking, some manufacturers have developed automated cooking equipment to replace manual labor. This equipment uses a screw conveyor to transport ingredients to the automated wok, achieving automated cooking and large-volume output. However, because the automated cooking equipment itself lacks a device for cleaning the screw conveyor, cleaning often requires manual spraying or injecting of water into the conveyor, making the cleaning process cumbersome and labor-intensive. Further improvements are needed to solve these problems. [Summary of the Invention]

[0004] In view of this, the object of the present invention is to provide a system with material conveying and distributing functions as well as cleaning functions, wherein the conveying device outputs the materials stored in the material warehouse to the outside, the cleaning device cleans the conveying device, and the material warehouse and the conveying device are separated by a baffle, thereby facilitating the cleaning of the conveying device and keeping the conveying device clean.

[0005] To achieve the above objectives, the present invention provides a material conveying system with a cleaning device, comprising a material silo, a conveying device, a baffle, and a cleaning device. The material silo is used to store materials and has at least one feeding outlet. The conveying device has a first inlet and a dispensing outlet, the feeding outlet leading to the first inlet and the first inlet leading to the dispensing outlet, the dispensing outlet being used to output materials. The baffle is disposed between the material silo and the conveying device to separate the material silo from the conveying device; the baffle forms at least one set of holes with the at least one feeding outlet, the at least one set of holes fitting into the at least one feeding outlet. The cleaning device includes a water tank and a water pump; the water tank is disposed directly below the baffle and the conveying device; the water pump draws liquid from the water tank and delivers it to the conveying device.

[0006] In use, the present invention is based on a material storage container. The first inlet of the conveying device receives the material output from the material storage container via the feeding outlet and transports the material to the ingredient outlet for output. When the material storage container contains ingredients for stir-frying, the conveying device can be used to deliver the stir-frying ingredients to an automated wok for cooking.

[0007] The advantage of this invention is that when the conveying device needs to be cleaned, the water pump draws cleaning liquid from the water tank and delivers it to the conveying device to clean it. After cleaning the conveying device, the liquid flows downwards and returns to the water tank, where it is then drawn back by the water pump and delivered to the conveying device again, thus achieving the effect of convenient cleaning of the conveying device. Furthermore, by using the baffle to separate the material storage area from the cleaning device, splashing of liquid into the material storage area during cleaning of the conveying device can be prevented, further maintaining the overall cleanliness of the material conveying system equipped with the cleaning device.

Implementation Method

[0009] To more clearly illustrate the present invention, preferred embodiments are described in detail below with reference to the accompanying drawings. Please refer to Figures 1 to 5, which illustrate a preferred embodiment of the material conveying system 100 with a cleaning device according to the present invention. The system comprises a material storage 20, a baffle 26, a conveying device 200, and a cleaning device 300 installed within a housing 10, wherein:

[0010] The outer casing 10 is a refrigerator. According to common user usage, the outer casing 10 has top and bottom sides, left and right sides, and front and back sides. The following description uses the outer casing 10 to define the orientation of each side, thereby describing the relative relationship between the outer casing 10 and its internal structure. A refrigeration unit 12 is installed on the rear side of the interior of the outer casing 10, enabling the interior of the outer casing 10 to maintain a temperature suitable for refrigerating and preserving food. The front of the outer casing 10 has multiple slots 14 arranged in a matrix. In this preferred embodiment, these slots 14 are divided into three rows from top to bottom. A door 16 is pivotally connected to the bottom side of each slot 14 on the front of the outer casing 10. Each door 16 closes each slot 14, and each door 16 can be pivotally opened forward by manual force or a drive mechanism.

[0011] On the upper part of one of the left and right sides of the outer casing 10, as in the preferred embodiment of this invention, there is a dispensing port 18 on the upper right side of the outer casing 10. A movable door 181 is provided at the dispensing port 18. Specifically, the movable door 181 is provided on the inner side of the dispensing port 18 in a manner that allows it to slide vertically. A movable door linear actuator 182 is connected to the portion of the outer casing 10 located below the dispensing port 18. The movable door linear actuator 182 is used to drive the movable door 181 to move downward to open the dispensing port 18, or to drive the movable door 181 to move upward to return to its original position and close the dispensing port 18. In this preferred embodiment, the movable door linear actuator 182 is a pneumatic cylinder. In other preferred embodiments, the movable door linear actuator 182 can also be a hydraulic cylinder or an electric push rod.

[0012] The material storage 20 and the conveying device 200 are respectively connected to the front and rear sides of the outer casing 10. The material storage 20 includes a plurality of tanks 22 arranged in a matrix. In this preferred embodiment, the tanks 22 are arranged in three rows from top to bottom. Each tank 22 is connected to the rear of each opening and closing door 16, so that the tanks 22 of the material storage 20 are located on the front side inside the outer casing 10. In this preferred embodiment, each tank 22 is used to store cooking materials, and each tank 22 has a material inlet 221 at its top. One of the tanks 22 of the material storage 20 is used to store seasonings, while the other tanks 22 are used to store materials for different dishes; preferably, the upper tank 22 is used to store vegetables, and the lower tank 22 is used to store meat. When any of the opening and closing doors 16 is pivoted forward, the trough 22 attached to the back of the opening and closing door 16 can tilt forward to expose the material inlet 221 above. At this time, the user can put the cooking ingredients into the trough 22 through the material inlet 221.

[0013] Referring to Figures 3 to 6, each of the tank bodies 22 has an inclined screw conveyor 24 formed on its bottom side. The interior of each screw conveyor 24 is connected to the interior of the tank body 22. Each screw conveyor 24 has a feeding outlet 241 at its upper end and a drive mechanism 242 at its lower end. Each feeding outlet 241 is located on the rear side of each tank body 22, and the front and rear positions of the feeding outlets 241 of the material storage 20 are roughly the same. A baffle plate 243 is attached to the portion of the outer surface of each screw conveyor 24 that is lower than the feeding outlet 241. Each baffle plate 243 is a U-shaped plate and is connected to the outer surface of each screw conveyor 24 by its inner edge. It is used to prevent liquid dripping from each feeding outlet 241 from flowing downward to each drive mechanism 242, so as to avoid affecting the operation of each drive mechanism 242 due to the liquid.

[0014] The baffle 26 is disposed behind the material storage 20 and is fixed inside the outer casing 10. The baffle 26, together with the feeding outlets 241, forms a plurality of sleeve holes 261 in a matrix arrangement. The sleeve holes 261 are arranged in three rows from top to bottom, and each sleeve hole 261 fits into each feeding outlet 241. Thereby, the baffle plates 243 connected to the screw conveyors 24 are located in front of the baffle 26 and are disposed between the material storage 20 and the conveying device 200 through the baffle 26, so as to separate the material storage 20 and the conveying device 200.

[0015] The baffle 26 forms an eave 262 on the upper side of each of the sleeve holes 261 other than the uppermost row. Each eave 262 covers the upper side of each sleeve hole 261, thereby preventing the material output from one of the upper feed outlets 241 of the material storage 20 from falling into the lower feed outlet 241 and entering the lower tank 22. This ensures that the material stored in the lower tank 22 is not contaminated or mixed with incorrect materials. In other preferred embodiments, the multiple slots 14 of the outer shell 10 may be divided into two rows, upper and lower. In this case, the opening and closing doors 16, the tanks 22, and the sleeve holes 261 are also divided into two rows, upper and lower, so that the sleeve holes 261 of the baffle 26 can respectively fit into each of the feed outlets 241 on the rear side of each tank 22.

[0016] Referring to Figures 4 to 5 and Figure 7, the conveying device 200 includes a first conveyor 30, a second conveyor 40, and a material distributor 50.

The lower edge of the baffle 26 is connected to the edge of the first inlet 321 near the baffle 26, and a feed hopper 322 is connected to the other edge of the first inlet 321 away from the baffle 26.

[0017] The first inlet 321 and the feed hopper 322 are both located below the feed outlets 241, so that the feed outlets 241 of the material storage 20 can lead downward to the first inlet 321 of the first conveyor 30. At one end of the first tubular shell 32, in this preferred embodiment, a first outlet 323 is formed at the right end of the first tubular shell 32, and at the other end of the first tubular shell 32, that is, the left end of the first tubular shell 32, a first bottom plate 34 is attached. The first bottom plate 34 closes the left end of the first tubular shell 32, and the first bottom plate 34 protrudes rearward to form a first support plate portion 341.

The cap 43 closes the discharge port 424. A bushing 431 is embedded in the center of the cap 43. The lower end of the second screw 46 is detachably pivotally connected to the bushing 431. A capping linear actuator 412 is pivotally connected between the other side of the linkage handle 411 and the other end of the pivot seat 41 away from the discharge port 424. Through the extension and retraction of the capping linear actuator 412, the cap 43 is pivoted relative to the pivot seat 41, thereby closing or opening the discharge port 424. As shown in Figures 3 and 3A, when the discharge port 424 is open, residue or liquid inside the second tubular shell 42 can be discharged downwards. In this preferred embodiment, the capping linear actuator 412 is a pneumatic cylinder; in other preferred embodiments, the capping linear actuator 412 can also be a hydraulic cylinder or an electric actuator.

[0020] Referring to Figures 3 and 5, the material distributor 50 is fixed to the upper side inside the housing 10 and located above the first conveyor 30. The material distributor 50 includes a track 52, a third conveyor 54, and a linear drive structure 56.

The upper ends of the first side plate 521 and the second side plate 522 are suspended and connected to the upper side of the housing 10. A through-hole 5211 is formed in the middle of the first side plate 521. The through-hole 5211 of the first side plate 521 is opposite to the dispensing port 18 of the housing 10. The dispensing port 18 is formed at the position of the housing 10 directly opposite the third conveyor 54.

[0021] Referring again to Figures 7 to 9, a first guide rod 523 and a second guide rod 524 are respectively connected to the upper and lower sides between the first side plate 521 and the second side plate 522. Two pulley seats 5212 are attached to the portion of the first side plate 521 corresponding to the lower side of the through-hole 5211. A pulley 5213 is rotatably attached to the upper end of each pulley seat 5212, and the upper side of each pulley 5213 extends slightly into the through-hole 5211. In other preferred embodiments, only one pulley seat 5212 or three or more pulley seats 5212 may be attached to the first side plate 521, and one of the aforementioned pulleys 5213 may be rotatably attached to the upper end of each pulley seat 5212.

[0022] The third conveyor 54 has a horizontally arranged third tubular shell 541. The third tubular shell 541 is a long straight tube extending in the left-right direction and with a U-shaped cross-section. An upwardly open third inlet 542 is formed on the upper side of the third tubular shell 541. The discharge nozzle 423 of the second conveyor 40 leads to the third inlet 542. The right end of the third tubular shell 541 passes through the outlet 5211 of the first side plate 521. The lower side of the third tubular shell 541 is abutted by each pulley 5213 through the outlet 5211. A feeding outlet 543 is formed at the right end of the third tubular shell 541. A hollow third screw support 5431 is provided at the feeding outlet 543.

[0023] A third base plate 544 is connected to the left end of the third tubular shell 541. The third base plate 544 closes the left end of the third tubular shell 541, and the third base plate 544 protrudes rearward to form a third support plate portion 5441. The upper and lower sides of the third support plate portion 5441 have a first bushing 5442 and a second bushing 5443, and the middle of the third support plate portion 5441 has a first nut 5444. A support plate 545 is connected to the outside of the third tubular shell 541. The support plate 545 is opposite to the third support plate portion 5441. The upper and lower sides of the support plate 545 have a third bushing 5451 and a fourth bushing 5452, and the middle of the support plate 545 has a second nut 5453. The first bushing 5442 and the third bushing 5451 are slidably fitted onto the first guide rod 523, and the second bushing 5443 and the fourth bushing 5452 are slidably fitted onto the second guide rod 524, thereby setting the third conveyor 54 on the track 52 in a manner that allows it to slide in a straight direction. A third screw 546 is rotatably installed inside the third tubular shell 541. One end of the third screw 546 is pivotally mounted on the third screw bracket 5431, and the other end of the third screw 546 pivotally passes through the third base plate 544. A third motor 547 is connected to the third support plate portion 5441, and the third motor 547 is connected to the other end of the third screw 546 through a combination of pulleys and belts.

[0024] The linear drive structure 56 is disposed between the track 52 and the third conveyor 54 to drive the third conveyor 54 to move along the track 52, so that one end of the third conveyor 54 with the dispensing outlet 543 extends outward through the dispensing port 18 opened by the housing 10, thereby moving the dispensing outlet 543 to a designated position. Specifically, the linear drive structure 56 includes a drive screw 561 and a drive motor 562. The drive screw 561 is rotatably disposed between the first side plate 521 and the second side plate 522. The drive motor 562 is coupled to the second side plate 522, and the drive motor 562 is connected to the drive screw 561 through a combination of pulley and belt. The first nut 5444 and the second nut 5453 of the third conveyor 54 are respectively screwed into the drive screw 561.

[0025] Please refer to Figures 3 to 6. The cleaning device 300 includes a water tank 60, a water pump 70, a spray structure 80, and a plurality of spray seats 90, all fixed inside the housing 10. The water tank 60 is used to hold liquid for cleaning the conveying device 200, such as cold water that can maintain a constant temperature inside the housing 10 to help preserve food. The water tank 60 is located at the bottom inside the housing 10 and directly below the baffle 26 and the conveying device 200. Due to the upward-opening design of the water tank 60, when the cleaning device 300 cleans the conveying device 200, the liquid overflowing from the conveying device 200 can drip down into the water tank 60, and the residue or liquid discharged from the discharge port 424 of the second conveyor 40 can also flow into the water tank 60.

[0026] The water tank 60 is also located directly below the baffles 243 of the screw conveyors 24, allowing liquid blocked by the baffles 243 to drip down into the water tank 60. In this preferred embodiment, one side of the bottom of the water tank 60 is higher and the other side is lower; the water pump 70 draws water from the lower part of the water tank 60 and then transports it to the spray structure 80 and the plurality of spray seats 90 through the liquid pipeline. In other preferred embodiments, the water tank 60 may also be divided into two structures: a water tank and a water collection tray. The water tank is used by the water pump 70 to draw liquid for cleaning purposes and transport it to the conveying device 200, while the water collection tray collects liquid dripping or discharged from the conveying device 200 and liquid dripping due to being blocked by the baffles 243.

[0027] The spray structure 80 includes a first support 82, a first water pipe 821, and a plurality of first nozzles 822. The first support 82 is connected between the first side plate 521 and the second side plate 522, and is located above the third conveyor 54. The first water pipe 821 is connected to the first support 82, and extends in the same direction as the track 52. One end of the first water pipe 821 is closed, and the other end is connected to the water pump 70. The first nozzles 822 are arranged at equal intervals in the left-right direction and are connected to the lower side of the first water pipe 821. The first nozzles 822 are connected to the first water pipe 821 and face the third inlet 542 of the third conveyor 54. In this way, the first nozzles 822 can evenly spray the liquid drawn by the water pump 70 into the third conveyor 54 for cleaning.

[0028] The spray structure 80 includes a second support 84, a second water pipe 841, and a plurality of second nozzles 842. The second support 84 is connected to the baffle 26 and is positioned vertically above the first conveyor 30 and below the material distributor 50. The second water pipe 841 is connected to the second support 84, and the direction in which the second water pipe 841 extends is the same as the direction in which the first tubular shell 32 extends. One end of the second water pipe 841 is closed, and the other end of the second water pipe 841 is connected to the water pump 70. The second nozzles 842 are arranged at equal intervals in the left-right direction and are connected to the lower side of the second water pipe 841. The second nozzles 842 face the feed hopper 322 of the first conveyor 30. In this way, the second nozzles 842 can evenly spray the liquid drawn by the water pump 70 into the first conveyor 30 for cleaning.

[0029] A plurality of spray seats 90 are arranged at equal intervals around the second tubular shell 42. Each spray seat 90 has a nozzle 92 in the middle. The inner end of each nozzle 92 communicates with the interior of the second tubular shell 42, and the outer end of each nozzle 92 communicates with the water pump 70. In this way, the nozzles 92 can evenly spray the liquid drawn by the water pump 70 into the second tubular shell 42 for cleaning.

[0030] When the above-described preferred embodiment of the present invention is used, please refer to Figures 3 and 5. When the material library 20 outputs cooking materials from one or more of the feeding outlets 241, the materials will fall into the first conveyor 30 due to gravity. Next, please refer to Figure 7. The first motor 38 drives the first screw 36 to rotate, so that the materials inside the first conveyor 30 are conveyed to the second inlet 421 of the second conveyor 40. After the second conveyor 40 receives the materials from the second inlet 421, please refer to Figure 6. The second motor 48 drives the second screw 46 to rotate, so that the materials inside the second conveyor 40 are conveyed to the second outlet 422 and output from the discharge nozzle 423. The materials output from the discharge nozzle 423 will enter the third conveyor 54 through the third inlet 542.

[0031] Please refer to Figures 3, 5 and 10. When the material conveying system 100 with a cleaning device distributes cooking materials to the automated woks at different locations through the material distributor 50, the movable door linear drive 182 drives the movable door 181 to descend and open the feeding port 18. Then, according to the position of the automated wok to which the material output from the material library 20 needs to be delivered, the drive screw 561 is rotated by the drive motor 562, so that the third conveyor 54, which is screwed to the drive screw 561 through the first nut 5444 and the second nut 5453, can extend one end of the third conveyor 54 with the feeding outlet 543 out of the feeding port 18 along the track 52, and move the feeding outlet 543 to above the automated wok to which the material is to be output. In this way, the materials conveyed from the material warehouse 20 to the third conveyor 54 via the first conveyor 30 and the second conveyor 40 can be output from the ingredient outlet 543 to the automated woks at different locations according to the position of the third conveyor 54 after it moves along the track 52.

[0032] Referring to Figures 3A to 6, when the preferred embodiment of this invention requires cleaning the conveying device 200, a cleaning liquid, such as cold water, is first injected into the water tank 60 of the cleaning device 300. Then, the water pump 70 draws liquid from the water tank 60 and sprays the liquid through the first nozzles 822 onto the third inlet 542 of the third conveyor 54, through the second nozzles 842 onto the feed hopper 322 of the first conveyor 30, and through the nozzles 92 into the interior of the second tubular shell 42.

[0033] Simultaneously, the rotational operation of the third screw 546, the first screw 36, and the second screw 46 agitates the liquid inside the third conveyor 54, the first conveyor 30, and the second conveyor 40, enabling the liquid to clean the interior of the third conveyor 54, the first conveyor 30, and the second conveyor 40. Finally, the liquid that cleans the third conveyor 54 flows outward from the feeding outlet 543, and the liquid that cleans the first conveyor 30 and the second conveyor 40 flows outward from the open discharge port 424 into the water tank 60. Then, the liquid flowing into the water tank 60, along with the liquid originally present in the water tank 60, will be drawn by the water pump 70 and transported to the conveying device 200 for cleaning the third conveyor 54, the first conveyor 30, and the second conveyor 40.

[0034] In the preferred embodiment of the present invention described above, the material storage 20, the baffle 26, the conveying device 200 and the cleaning device 300 are disposed inside the outer casing 10. The refrigeration device 12 provided in the outer casing 10 reduces the temperature inside the outer casing 10, so that the materials stored in the material storage 20 can be refrigerated and kept fresh. Furthermore, the materials output from the material storage 20 can also be kept fresh due to the low temperature environment inside the outer casing 10 during the process of being conveyed by the conveying device 200. In other preferred embodiments, if the material conveying system 100 with the cleaning device is located in a low-temperature environment, or if the material distributed by the material conveying system 100 with the cleaning device does not require low-temperature preservation, the material storage 20, the first conveyor 30, the second conveyor 40, and the material distributor 50 can be fixed to an open base, support, frame, or other structure. As long as the material storage 20, the first conveyor 30, the baffle 26, the conveying device 200, and the cleaning device 300 are kept in relative positions, the same effect as the preferred embodiment described above can be achieved: the material output from the material storage 20 can be sent to different locations for distribution, and the conveying device 200 can be cleaned using the cleaning device 300.

[0035] In addition to the preferred embodiment described above, the material storage 20 may include a plurality of tanks 22, or it may contain only a single tank to store cooking materials, with at least one feeding outlet at the rear of the tank outputting the required materials to the first conveyor 30. Besides using the screw conveyor 24 disposed on the tank 22 to deliver the materials from the tank to the feeding outlet 241, the material storage 20 may also use a tracked conveyor or a machine with the same function to move the materials from the tank 22 to the feeding outlet 241. The first conveyor 30, the second conveyor 40, and the third conveyor 54 may be either screw conveyors or tracked conveyors. In addition to the drive screw 561 driving the third conveyor 54 to move along the track 52, the linear drive structure 56 of the material distributor 50 can also be replaced by an electric push rod set between the track 52 and the third conveyor 54 to drive the third conveyor 54 to slide linearly along the track 52, so that the material outlet 543 can stop at a designated position to output materials after moving.

[0036] The above description is only a preferred embodiment of the present invention. Any equivalent changes made by applying the present invention specification and the claims should be included within the patent scope of the present invention. [Simplified Explanation of the Diagram]
