Description

Technical Field

[0001] The invention relates to the technical field of automated equipment, in particular to a large plate screening device for tableware classification. Background Art

[0002] With the development of China's economy, people have become richer, and more and more people are dining out, resulting in a huge amount of tableware used in restaurants. At present, automated washing lines have been widely used in the catering industry, but the sorting of a pile of various tableware still relies mainly on manual work, which requires a lot of human resources, and there are very few designs for large-scale screening devices.

[0003] The existing tableware filtering device has a slow filtering speed for large plates with large plate diameters. An automated production line for filtering, separating and flipping plates with large plate diameters to achieve orderly collection of the same state has not yet been developed. However, in the catering industry, it is extremely important to quickly screen each type of tableware and sort and collect the same state. Summary of the invention

[0004] In order to solve the above-mentioned shortcomings in the implementation and application of the prior art, the main purpose of the present invention is to provide a large plate screening device for classifying tableware, by arranging a conveying mechanism, a guide partition frame, a filter grid, a baffle, an identification device, a first pushing device and a flipping device. The guide partition frame is mounted on the conveyor belt to regulate the conveying order of the tableware, the filter grid is arranged behind the guide partition frame for other tableware other than the large plate, the baffle is arranged above the filter grid to sweep the tableware other than the large plate into the filter grid, and the flipping device flips the large plate with the front side facing up / the back side facing up so that the plate openings of all the large plates are finally oriented in the same direction, in order to overcome the difficulties in the prior art and realize practical applications.

[0005] Technical means for solving the problem, in order to achieve the above-mentioned purpose, the present invention provides a large plate screening device for tableware classification, characterized in that it comprises: a first conveying mechanism, the first conveying mechanism comprises a guide partition frame and a filter grid, the guide partition frame is mounted on the first conveying mechanism, the filter grid is arranged downstream of the guide partition frame, a gap is provided between the bottom of the guide partition frame and the first conveying mechanism, and the size of the filter grid is smaller than the size of the large plate so that the large plate can pass through the filter grid quickly;

[0006] A second conveying mechanism, which is disposed downstream of the first conveying mechanism and is used to identify the forward and reverse directions of the large disks and separate the large disks in one direction;

[0007] The third conveying mechanism is arranged adjacent to the second conveying mechanism and receives the large disk separated by the second conveying mechanism. The third conveying mechanism is provided with a flipping device to flip the direction of the large disk.

[0008] Furthermore, the guide partition frame is provided with a plurality of intervals for evenly distributing tableware other than the large plate on the first conveying mechanism. By providing the guide partition frame, only tableware other than the large plate is allowed to pass through, and the tableware is evenly distributed on the conveyor belt after passing through the intervals, while the large plate quickly passes through the gap between the guide partition frame and the conveying mechanism. In the process of screening the large plate, the guide partition frame creates a time difference between the conveyance of the large plate and other tableware, thereby realizing rapid screening of the large plate.

[0009] Furthermore, the multiple intervals on the guide partition frame and the multiple grids of the filter grid are aligned along the conveying direction of the first conveying mechanism. After being guided by the guide partition frame, they are evenly distributed. Due to the alignment of the intervals and the grids, other tableware other than the large plate can also be accelerated to quickly enter the grid to improve the filtering speed.

[0010] Furthermore, the first conveying mechanism also includes a baffle, which is arranged above the filter grid and is used to block objects retained on the large plate. The baffle can block objects retained above the large plate and block them into the filter grid.

[0011] Furthermore, a detachable guide bar is provided downstream of the filter grid to transport the large plates in a single row in an orderly manner. A movable conveyor belt is provided on the guide bar, and the large plates are arranged on the conveying mechanism in a sequential order under the guidance of the guide bar.

[0012] Furthermore, the second conveying mechanism includes an identification device for identifying the front and back directions of the large plate and a first pushing device arranged downstream of the identification device for pushing the large plate in one of the front and back directions. The identification device is arranged on the second conveying mechanism, and the first pushing device is used to push the large plate facing up or the large plate facing up to the third conveying mechanism.

[0013] Furthermore, the identification device includes an elastic bar and a third sensor, the elastic bar is arranged on the second conveying mechanism, and the third sensor is arranged near the elastic bar. Under the guidance of the guide bar, the large plate will pass through the elastic bar and the third sensor one by one. The large plate squeezes the elastic bar and then blocks the sensor, which can quickly identify whether the plate opening is upward or downward, thereby realizing the identification of the direction of the plate opening.

[0014] Furthermore, a connecting plate is provided between the second conveying mechanism and the third conveying mechanism as a conveying bridge. The connecting plate has a certain inclination, which facilitates the pushing component to convey the large plate to the adjacent conveyor belt through the connecting plate.

[0015] Furthermore, the flipping device includes a fan blade rotating structure and a fourth sensor, and the fan blade rotating structure rotates according to a signal detected by the fourth sensor. The fan blade rotating structure can flip the plate in the direction of the plate opening.

[0016] Furthermore, a first sensor and a second pushing device are provided downstream of the flipping device, and a second sensor is provided on the second conveying mechanism. The second pushing device pushes the large disk to the second conveying mechanism according to the detection signals of the first sensor and the second sensor. The function of the flipping device is to eventually make the disk opening orientations of all the large disks on the second conveying mechanism and the third conveying mechanism consistent. When a large disk passes through the conveyor belt mechanism provided with the second pushing device and no large disk passes through the adjacent conveying mechanism, the second pushing device pushes the large disk to the adjacent conveying mechanism according to the control signal of the PLC controller. This enables all the large disks to be finally gathered on the same conveying mechanism for transportation, and also avoids collisions with large disks on adjacent conveying belts when the pushing component is in motion.

[0017] The present invention proposes a large plate screening device for tableware classification, including providing a large plate screening device for tableware classification, by setting a conveying mechanism, a guide baffle frame, a filter grid, a baffle, an identification device, a first pushing device and a flipping device, the guide baffle frame is set on the conveyor belt to regulate the conveying order of the tableware, so that the tableware other than the large plate can enter the filter grid faster to achieve the effect of rapid filtering, the baffle is set above the filter grid to sweep the tableware other than the large plate into the filter grid, and the flipping device flips the large plate with the front side facing up / the back side facing up on another conveyor belt so that the plate openings of all the large plates are finally in the same direction. This automated large plate screening device for tableware classification can realize the rapid screening of large plates from a large number of tableware mixed with large plates, bowls, cups, bottles, spoons and chopsticks, and can quickly make the plate openings of all the large plates present a state of consistent orientation for reorganization.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the large plate screening structure for tableware classification includes a first conveying mechanism 1, the first conveying mechanism 1 includes a guide partition frame 2 and a filter grid 3, the guide partition frame 2 is mounted on the first conveying mechanism 1, the filter grid 3 is arranged downstream of the guide partition frame 2, and a gap is provided between the bottom of the guide partition frame 2 and the first conveying mechanism 1 for only large plates to pass quickly, and the size of the filter grid 3 is smaller than the size of the large plate so that the large plate can pass quickly through the filter grid 3;

[0029] A second conveying mechanism 100, which is lower than the first conveying mechanism 1 and is arranged at the end of the first conveying mechanism 1, and includes an identification device 6 for identifying the front and back directions of the large plate and a first pushing device 7 arranged downstream of the identification device 6 for pushing the large plate in one of the front and back directions;

[0030] The third conveying mechanism 200 is arranged adjacent to the second conveying mechanism 100 and receives the large plate pushed by the first pushing device 7. The third conveying mechanism 200 is provided with a flipping device 8 to flip the direction of the large plate. The flipping device 8 includes a fan blade rotating structure and a fourth sensor. The PLC controller (not shown in the figure) controls the fan blade rotating structure to rotate according to the signal detected by the fourth sensor. The fan blade rotating structure can flip the front and back sides of the plate. The fan blade is driven by the motor and controlled by the PLC controller (not shown in the figure) to rotate 45 degrees each time. The rotation angle is determined by the number of the fan blades. When it rotates to 180 degrees, it is output to the conveyor belt for continued transportation.

[0031] In a specific embodiment, Figure 2 As shown, a detachable guide bar 5 is provided between the filter grid 3 and the identification device 6 to regulate the order of the large plates. The minimum distance D between the guide bar 5 and the first conveying mechanism 1 is greater than the plate diameter of the large plate, and in this embodiment, the range value is between 120-200 mm. The guide bar 5 can make the large plates pass by the identification device 6 in an orderly manner, so that the identification device 6 can judge the direction of each large plate.

[0032] In a specific embodiment, Figure 3 As shown, a first sensor 10 and a second pusher 9 are provided downstream of the turning device 8, and a second sensor 11 is provided on the second conveying mechanism 100. The second pusher 9 pushes the large plate to the second conveying mechanism 100 according to the detection signals of the first sensor 10 and the second sensor 11. A large plate passes on one side of the conveyor belt provided with the second pusher 9. When the second sensor 11 detects that no large plate passes on the second conveying mechanism 100, the second pusher 9 pushes the large plate to the adjacent conveyor belt according to the control signal of the PLC controller (not shown in the figure). It can be achieved that all large plates are finally collected on the same conveyor belt for transportation, and it can also avoid collisions with large plates on adjacent conveyor belts when the pusher is in action. Among them, the conveying speed of the third conveying mechanism 200 is greater than twice the conveying speed of the second conveying mechanism 100, so that it can be ensured that the large plate can be smoothly returned to the second conveying mechanism 100 after being turned over by the turning device 8 and pushed out by the second pusher 9.

[0033] In a specific embodiment, Figure 3As shown, a connecting plate 12 is provided between adjacent conveyor belts, wherein any section of the conveyor belt provided with the first pushing device 7 and the second pushing device 9 is higher than an adjacent section of the conveyor belt, that is, one end of the connecting plate 12 located on the same side as the first pushing device 7 and the second pushing device 9 is higher than the other end. The connecting plate 12 is provided, and one end of the connecting plate 12 is higher than the other end in order to assist the pushing component to quickly push the plate from one conveyor belt to another conveyor belt.

[0034] In a specific embodiment, Figure 4 As shown, the guide partition frame 2 is provided with a plurality of intervals for evenly distributing tableware other than the large plate on the first conveying mechanism 1. The intervals can be composed of a plurality of first partitions 21, and the gaps between the plurality of first partitions 21 and the first conveying mechanism 1 are slightly larger than the height of the large plate, which can be between 20-30 mm, so that the large plate can pass through the gaps quickly, while other tableware can only pass through between the partitions. The filtering grid 3 can be composed of a plurality of second partitions 31, and the side length C of the second partition 31 along the conveying direction of the first conveying mechanism is slightly smaller than the plate diameter of the large plate, which can be between 80-100 mm.

[0035] In a specific embodiment, Figure 4 As shown, in a specific embodiment, the spacing B1 between the plurality of first baffles 21 is equal to the spacing B2 between the plurality of second baffles 31. The first baffles 21 and the second baffles 31 are aligned and can be aligned with the filter grid 3 after passing through the guide baffle frame 2 to achieve rapid filtration.

[0036] In a specific embodiment, Figure 5 As shown, the identification device 6 includes an elastic bar 61 and a third sensor 62. The third sensor 62 is arranged close to the elastic bar 61. The elastic bar 61 is arranged behind the filter grid 3 to block the third sensor 62 according to the compression of the large plate. By setting the large plate to compress the elastic bar 61 and then block the sensor, it is possible to quickly identify whether the plate opening is upward or downward, thereby realizing the identification of the direction of the plate opening. In this embodiment, the spring bar 61 and the third sensor 62 are arranged in pairs, and the third sensor 62 is a U-shaped photoelectric switch, wherein the height E of the spring bar 61 can be between 7-9 mm, which is lower than the height when the large plate is facing upward, and the angle F between the spring bar 61 and the second conveying mechanism 100 can be between 10-30 degrees. The width of the large plate that can be accommodated on both sides of the second conveying mechanism 100 is slightly larger than the diameter of the large plate by 2-5 mm, and the distance between the convex rafters of the spring bar 61 on both sides is slightly smaller than the size of the large plate by 5-10 mm. According to the elastic force of the spring bar 61, the large plate with its mouth facing downward can push the spring bar 61 and pass through the spring bar 61 smoothly.

[0037] The working principle of the large plate screening device for tableware classification of this embodiment is as follows: large plates, cups, bottles, spoons and other tableware (including but not limited to the above tableware) are transported by the first conveying mechanism 1 through the guide partition frame 2 mounted on the first conveying mechanism 1, and the large plates quickly pass through the gap between the guide partition frame 2 and the first conveying mechanism 1. The guide partition frame 2 is composed of a plurality of first partitions 21, and a certain spacing is formed between the partitions. The remaining tableware passes between the partitions, and the first partition 21 corresponds to the second partition 31. When the remaining tableware passes through the first partitions 21 and is transported to the filtering grid 3 formed between the second partitions 31, it quickly falls. The baffle 4 above the filtering grid 3 can block the components on the large plate. Since the diameter of the bowl mouth of the large plate is larger than the length of the filtering grid 3 and also larger than the spacing between the second partitions 31, the large plate can directly pass through the filtering grid 3, thereby completing the rapid screening of the large plate from a large number of tableware.

[0038] At this time, the large plates have the front side facing upward and the back side facing upward. After passing through the guide bar 5, the large plates are arranged in a standardized manner and fall into the second conveying mechanism 100 one by one, and flow through the elastic bar 61. It can be set that the large plate with the plate mouth facing downward squeezes the elastic bar 61, or the large plate with the plate mouth facing upward squeezes the elastic bar 61 when passing through the elastic bar 61, and the elastic bar 61 blocks the third sensor 62, and the large plate that is not squeezed by the elastic bar 61 continues to be conveyed forward. The large plate squeezed by the elastic bar 61 is controlled by the PLC controller (not shown in the figure) according to the signal of the third sensor 62. The first pushing device 7 (which can be a pushing cylinder) pushes the large plate with the plate mouth facing downward or facing upward to the adjacent conveyor belt, so as to separate the large plate with the plate mouth facing upward and the plate mouth facing downward. A turning device 8 is set on the conveyor belt adjacent to the first pushing device 7, and the large plate is conveyed to the fan blade rotating structure of the turning device 8. Under the drive of the motor, the PLC controller (not shown in the figure) controls the fan blade to rotate a certain angle each time to finally turn the large plate to the other side opposite to the original side, so as to achieve the consistency of the plate mouth direction of all the plates in the end.

[0039] In addition, a second pushing device 9 can be arranged below the flipping device 8, a first sensor 10 can be arranged on one side of the second pushing device 9, and a second sensor 11 can be set on the adjacent conveyor belt to detect whether there is a plate passing opposite the second pushing device 9. If no plate passes, the second pushing device 9 pushes the flipped large plate from the inclined connecting plate 12 to the adjacent conveyor belt, so that all the plates are collected and transported on the same conveyor belt.

[0040] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above invention concept.
