Description

Technical Field

[0001] The present invention relates to a tableware cleaning device, and particularly to a brush-type tableware cleaning device. Background Art

[0002] With the rapid development of the catering industry and the increasing emphasis on hygiene conditions by people, industrial tableware washing machines are increasingly widely used in various occasions.

[0003] Existing industrial tableware washing machine technologies have the following characteristics: a. In terms of structure, existing industrial tableware washing machines mainly include a transmission system, a spraying system, a detergent supply system, a control system, etc. The transmission system is responsible for conveying the tableware to be cleaned into the cleaning area; the spraying system sprays the detergent onto the surface of the tableware through high-pressure water flow to achieve decontamination; the detergent supply system is responsible for providing the detergent to the spraying system; the control system is used to control the operation of the entire device. b. In terms of washing technology, industrial tableware washing machines mainly use technologies such as spraying, ultrasonic waves, and eddy currents for cleaning. Spray cleaning sprays the detergent onto the surface of the tableware through high-pressure water flow to remove stains on the tableware; ultrasonic cleaning uses high-frequency vibration to generate cavitation effects to make the stains fall off from the surface of the tableware; eddy current cleaning forms vortices through high-speed water flow, causing the tableware to generate centrifugal force in the vortices to achieve the cleaning effect. c. In terms of energy utilization, existing industrial dishwashers mainly use resources such as electricity, gas, and water. Some highly energy-efficient tableware cleaning machines adopt a heat recovery system to improve energy utilization efficiency. Currently, existing industrial tableware washing machines have problems such as unstable washing effects, too long production lines, and high energy consumption that urgently need to be improved. Summary of the Invention

[0004] The object of the present invention is to overcome the deficiencies of existing tableware cleaning machines and provide a new highly energy-efficient device with good washing effects, high efficiency, stable performance, and a shorter production line.

[0005] The technical solution for the present invention to solve its technical problems lies in that an intelligent robotic arm drives a suction cup (14), and uses vacuum suction to grab a bowl (15) and a dinner plate (39) and brush them on a profiling brush; a swing device (17) is installed on a suction cup conduit (16) to drive the bowl to swing and brush on the profiling brush; the profiling brush is made according to the shape of the part of the tableware to be cleaned, and is composed of an inner bowl profiling brush (7), an outer bowl profiling brush (24), a dinner plate concave brush (37), a dinner plate surface brush (38), a groove brush (43), and a bottom side brush (4); a brush convex band (34) and a brush concave (33) are provided on the surface of the profiling brush, a water spraying port (35) is provided on the brush concave, a brush handle water pipe (28) is provided inside the brush handle (27); a brush inner cavity (32) is provided inside the brush head (31) and is communicated with the water spraying port.

[0006] The beneficial effects of the present invention are as follows: By using an intelligent robotic arm, the profiling brush is driven to perform a 360-degree all-round cleaning without dead angles, integrating cleaning and spraying, improving the operation efficiency and stability, shortening the length of the production line, and achieving the beneficial effects of high efficiency and energy conservation.

[0011] It can be seen from Figure 1 Figure 2 that the profiling brush motor 1 drives the brush shaft 2 to rotate through the transmission belt 3. The upper end of the brush shaft is connected to the brush handle 27 of the inner bowl profiling brush 7, and the water suction pump 5 is installed at the lower end. When the profiling brush motor 1 rotates and works, the water suction pump 5 sucks in the cleaning liquid through the water supply pipe 9, passes through the brush shaft 2 (inner pipe), brush handle water pipe 28, brush inner cavity 32, and spray pipe 8, and sprays out from the water spray opening 35, realizing the cleaning effect of integrating brushing and spraying. And by using a sensor, the spraying and closing of the cleaning liquid on the brush head are controlled to achieve energy conservation.

[0012] As shown by Figure 1 and Figure 2 , a suction cup 14 is installed at the lower side of the suction cup conduit 16 for grasping and controlling the (tableware) bowl 15. When the conveyor belt transports the bowl into the area to be brushed of the brushing device, the intelligent robotic arm starts to work. The boom driver 10 drives the boom 12 to tilt forward, the forearm driver 13 drives the forearm 20 and the connecting rod 19 downward, and the connecting rod controller 21 will cooperate to adjust the direction so that the suction cup 14 accurately presses downward on the bottom of the bowl. The outer suction cup controller 18 is opened simultaneously, and using the suction force of a vacuum pump (not shown in the figure), the bowl is firmly sucked, and the bowl is placed on the bowl inner profiling brush 7 rotating at high speed by the robotic arm. The bowl is driven by the oscillator 17 for oscillating brushing. After the inner surface and the rim of the bowl are brushed, the intelligent robotic arm lifts the bowl, and the connecting rod driver 21 drives the connecting rod to rotate outward by 90 degrees, with the bowl opening facing outward. At this time, the intelligent robotic arm on the opposite side (see Figure 2 ) has rotated the inner suction cup conduit 26 outward by 90 degrees and is waiting on the opposite side. When the inner suction cup 25 presses tightly against the inner bottom of the bowl, the inner suction cup controller 23 is opened. At the same time, the outer suction cup controller 18 is closed, and under the action of the vacuum suction force, the inner suction cup takes over the bowl. The robotic arm places the bowl in the profiling groove of the bowl outer profiling brush 24 for brushing, and at the same time, the oscillator 17 drives the bowl to perform oscillating brushing through the inner suction cup conduit 26 and the inner suction cup 25. After completing a 180-degree swing, the outer surface and the bottom of the bowl are all brushed in place. Then, the bowl is placed on the conveyor belt by the intelligent robotic arm and fed into the next process.

[0013] Figure 3 is a sectional view of the bowl inner profiling brush 7 and the bowl outer profiling brush 24. The outer shapes of the two profiling brushes are different, but the structural principles are the same. An inner cavity 32 is provided inside the brush head 31 and is connected to the water spray nozzle 35 through the spray pipe 8. The outer surface of the brush head is provided with an inclined brush convex band 34 and brush recesses 33, and a brush head thread 30 is provided at the lower side for connecting with the brush holder 29, which is detachable, facilitating the replacement of the brush head and the cleaning of blockages. The brush convex is made into a strip shape and can also be made into other-shaped protrusions according to needs. Water spray nozzles 35 are distributed on the brush recesses 33, which play a triple role of flushing tableware, cleaning the brush head, and discharging residues.

[0014] As shown by Figure 4 , there is a food recess 36 on the front surface of the dinner plate 39. According to the surface shape of the dinner plate, two horizontal profiling brushes are customized: the dinner plate recess brush 37 and the dinner plate surface brush 38. Their structural principles are the same as those of the bowl profiling brush and are respectively used for brushing the food recess and the front surface of the dinner plate. According to needs, the dinner plate recess brush and the dinner plate surface brush can also be made into vertical profiling brushes (such as Figure 3 Figure 5 ).

[0015] As shown by Figure 5It can be seen that there are two "cross"-shaped grooves 40, and the bottom side edges 41 and the bottom plane of the four inclined surfaces of the "rectangle" on the back 44 of the dinner plate, which need to be cleaned. According to the shape of the bottom surface of the dinner plate, two vertical profiling brushes are customized, namely the side brush 42 and the groove brush 43, and the structural principle is the same as that of the profiling brush for the bowl. On the dinner plate brushing production line, two groups of brushes are required. One group of brushes the long side and the long groove, and then the swing device 17 drives the dinner plate to rotate 90 degrees; then another group of brushes brushes the two short sides and the short grooves. Both the side brush and the groove brush have a bottom brush position 45, which also has the function of brushing the bottom surface. After the two groups of brushing, it is completely possible to achieve no dead angle and all-round brushing of the back of the dinner plate. It can also be customized into a horizontal brush according to needs (such as Figure 4 ).

[0016] In Figure 4 Figure 5 , except for the different appearance from the profiling brush for the bowl, the other structural principles of the profiling brush for the dinner plate are the same, and will not be described repeatedly here.

[0017] The intelligent robotic arm and control system of the present invention are already mature technologies, and the working principle of the intelligent robotic arm for washing bowls and dinner plates is the same, and will not be described here. Due to the large volume of the dinner plate, a group of four suction cups are required to hold a dinner plate for work at the same time. Since the dinner plate is relatively long, the profiling brush needs to brush from one end to the other end, and the profiling brush needs to move horizontally during the brushing operation. It is also possible to design that the profiling brush does not move and the robotic arm holds the dinner plate to move for brushing.

[0018] In another embodiment, according to actual needs, the suction cup 14 can be decomposed into multiple ones to increase the holding force. The water suction pump 5 can also be omitted, and a large water pump is used to uniformly supply the cleaning liquid, achieving an energy-saving effect.

[0019] The present invention has the advantages of high efficiency and energy saving, and can be widely applied to large, medium and small tableware cleaning equipment.
