Description

Technical Field

[0001] The invention relates to the technical field of tableware arrangement, and in particular to a screening device for plates and spoons. Background Art

[0002] With economic development, people's living standards are getting better and better, and the number of people eating out is increasing, resulting in a huge amount of tableware used in restaurants. Although there are many automatic tableware washing lines on the market, in fact, the subsequent sorting and packaging still needs to be done manually, so there is a huge market space to be tapped.

[0003] Although there are some simple equipment on the market, the technology is still immature and the degree of automation is low. Therefore, there is still a large equipment gap in tableware sorting. In the process of industrial production or cleaning, it is often necessary to sort and arrange the messy lightweight objects (such as saucers and spoons) in an orderly manner. However, if the objects to be sorted are relatively light, especially when they are irregular in shape, it is difficult to sort them automatically. There is a large equipment gap in tableware sorting. There are some research and development equipment on the market, but the technology is still immature and the degree of automation is low. There are still some problems in the screening of saucers and spoons. The existing network chain screening saucer spoons on the market have the problems of incomplete screening, large equipment size, high cost, and manual re-screening required in the later stage, which is costly and inefficient. Summary of the invention

[0004] The purpose of the present invention is to propose a screening device for dish spoons to address the problems of incomplete screening, large equipment size, high cost, need for manual post-screening, high cost and low efficiency in the prior art of screening of dish spoons by net chains.

[0005] The present invention provides a screening device for dish spoons, comprising a sorting component, a spacing component and a screening component, wherein the sorting component, the spacing component and the screening component are connected in parallel in sequence, and the sorting component and the spacing component are used to sort the dish spoons to be screened in a single straight line and at intervals, and the screening component comprises two parallel transmission belts and a buffer plate, and the buffer plate is tilted and rotatably erected between the spacing component and the transmission wheel group, and the spacing between the two transmission belts is greater than the width of the spoon head and less than the maximum diameter of the dish. Through the combined arrangement of the sorting component, the spacing component and the screening component, the fast and efficient separation operation of the dish and the spoon is achieved.

[0006] Furthermore, the transfer and screening assembly also includes a limit plate and a third conveyor belt, wherein the limit plates are arranged on both sides of the two conveyor belts, and the third conveyor belt is arranged below the two conveyor belts. The third conveyor belt is arranged to transport the spoons to the next process in time to avoid the occurrence of situations such as the spoons being broken due to collisions between the spoons.

[0007] Furthermore, the conveyor belt is a round belt conveyor belt connected by a transmission wheel set and arranged below the buffer plate. The round belt conveyor belt is a flexible material with elasticity, which is not only convenient for rapid screening but also can prevent the occurrence of collisions and the like.

[0008] Furthermore, the sorting assembly includes a first guide transmission member, a second guide transmission member and a third guide transmission member, and the axes of any two adjacent guide transmission members of the first guide transmission member and / or the second guide transmission member and / or the third guide transmission member intersect, and the angle of intersection is less than 90 degrees. With the setting of the intersection of the axes of adjacent guide transmission members, the spoons of the dishes to be sorted can be arranged quickly in a single straight line and at regular intervals.

[0009] Furthermore, the sorting assembly further comprises a first conveyor belt arranged at the bottom, and the conveying surface speed of the first conveyor belt is less than the guide transmission surface speed of the first guide transmission member and / or the second guide transmission member and / or the third guide transmission member. By reasonably setting the speed, the spoons of the dishes to be sorted can be outputted in a single straight line and at intervals.

[0010] Furthermore, the third guide transmission member and the first conveyor belt form a sorting discharge port, and the sorting discharge port is arranged above the spacing component, the sorting discharge port is provided with a sorting inclined surface, and a first baffle plate is arranged on the side of the sorting inclined surface. With the arrangement of the sorting inclined surface and the first baffle plate, the spoon head and / or the spoon handle are discharged forward.

[0011] Furthermore, the spacing assembly comprises a second conveyor belt and a guide plate, wherein the guide plates are arranged on both sides of the second conveyor belt. By virtue of the arrangement of the guide plates, the spoon of the sauce dish to be screened can accurately fall onto the second conveyor belt.

[0012] Furthermore, the conveying surface speed of the second conveyor belt is greater than the component speed of the guide transmission surface speed of the third guide transmission member along the conveying direction of the first conveyor belt. By setting the speed of the second conveyor belt, the spacing between the spoons of the single dish to be screened is widened.

[0013] Furthermore, the guide plates on both sides are arranged tilted toward one side of the second conveyor belt. With the tilted arrangement of the guide plates, the spoon of the sauce dish to be screened can fall accurately onto the second conveyor belt.

[0014] Furthermore, the end of the second conveyor belt is provided with a spaced discharge port, and the spaced discharge port is located above the buffer plate. With the arrangement of the buffer plate, the spoon of the dish to be screened can slide smoothly onto the two conveyor belts.

[0015] The screening device for dish spoons of the present invention realizes the fast and efficient separation operation of the dish spoons to be screened by the combination arrangement of the sorting component, the spacing component and the screening component. The combined optimized design of the two conveyor belts and the buffer plate has a simple structure, is easy to maintain, has low cost and high economic benefits, and realizes the automatic loading of the dish spoons to be screened and the efficient separation of the dish spoons to be screened. Not only is the screening efficiency high, but also no manual re-screening link is required. Compared with the mesh chain screening in the prior art, it is more efficient, simpler in structure, lower in cost, occupies less space, replaces manual labor, reduces labor costs, improves productivity, and is convenient for improving the tableware sorting production line to make it more automated.

It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present invention. Therefore, the following detailed description should not be adopted in a limiting sense, and the scope of the present invention is defined by the appended claims.

[0023] Figure 1 FIG. 1 is a schematic diagram of the overall structure of a screening device for a dish spoon according to a specific embodiment of the present invention. Figure 1 As shown, the device includes a sorting component 100, a spacing component 200 and a screening component 300 which are connected in sequence and in parallel. The spoons of the sauce dishes to be screened are transported by the first conveyor belt 140, and after the first sorting by the first guide transmission member 110, the second sorting by the second guide transmission member 120 and the third sorting by the third guide transmission member 130, the spoons of the sauce dishes to be screened form a single straight line and are neatly sorted, and are output to the second conveyor belt 220 on the spacing component 200 through the guide plate 210, so that the intervals between the spoons of the sauce dishes to be screened are lengthened, and they are transported into the screening component 300 separately in sequence, and the hollow setting between the conveyor belts 340 is utilized so that the spoons entering the screening component 300 fall from the middle hollow gap to the third conveyor belt 330 for output, and the sauce dishes pass smoothly and are output to the next process by the transmission of the conveyor belt 340.

[0024] In a specific embodiment, reference Figure 2 , Figure 2 1 is a structural stereogram of a sorting assembly of a screening device for a dish spoon according to a specific embodiment of the present invention. Figure 2As shown, the sorting assembly 100 includes a first conveyor belt 140 disposed on a base, the first conveyor belt 140 is configured to have a conveying direction a, and a first guide transmission member 110, a second guide transmission member 120 and a third guide transmission member 130 are rotatably mounted on the first conveyor belt 140, which are respectively configured to have a transmission direction b, a transmission direction c and a transmission direction d, and the axes of two adjacent guide transmission members intersect, and the included angle is less than 90°. Specifically, the included angle between the transmission direction b and the conveying direction a is taken from the interval range of 50°-70°, the included angle between the transmission direction c and the conveying direction a is taken from the interval range of 25°-35°, and the included angle between the transmission direction d and the conveying direction a is set to the interval range of 30°-40°. The speed of the conveying surface of the first conveyor belt 140 is lower than the speed of the guide transmission surfaces of the first guide transmission member 110 and / or the second guide transmission member 120 and / or the third guide transmission member 130. Specifically, the speed of the conveying surface of the first conveyor belt 140 is set to 80-110 mm / s, and the speeds of the guide transmission surfaces of the first guide transmission member 110, the second guide transmission member 120 and the third guide transmission member 130 are set to 400-430 mm / s, 510-540 mm / s and 610-640 mm / s, respectively, to meet the sorting and conveying process of the spoons of the selected condiments in the sorting component 100 from slow to fast. While the spoons of the sauce dishes to be screened are being conveyed in direction a by the first conveyor belt 140, they are conveyed in direction b by the guide transmission surface of the first guide transmission member 110 in the first sorting link, in direction c by the guide transmission surface of the second guide transmission member 120 in the second sorting link, and in direction d by the guide transmission surface of the third guide transmission member 130 in the third sorting link. In addition, since the speed of the conveying surface of the first conveyor belt 140 is relatively low, simple and preliminary interval sorting is also performed during the linear sorting process of passing through the first guide transmission member 110, the second guide transmission member 120 and the third guide transmission member 130 in sequence. In the first sorting link, the spoons of the dishes to be screened transported by the first conveyor belt 140 can contact the guide transmission surface on the first guide transmission member 110 and produce a certain collision. When the spoons of the dishes to be screened collide with the first guide transmission member 110, the spoons of the dishes to be screened that are gathered together can be separated from each other, and under the joint action of the first guide transmission member 110 and the first conveyor belt 140, the separated spoons of the dishes to be screened can also rotate and move toward the transmission direction b. The principles of the second and third sorting links are similar, and will not be described in detail here. Although, Figure 1 and 2The arrangement of three guide transmission members is shown in FIG. It can be associated that at least one guide transmission member can be arranged, which is specifically arranged according to the number and process specifications of the spoons of the sauce dishes to be screened. The third guide transmission member 130 and the first conveyor belt 140 form a sorting discharge port 150, and the distance from the sorting discharge port 150 to the first baffle plate 160 is less than the length of the spoon body, and can be specifically set to an interval range of 100mm-120mm, which is approximately equal to the sum of the length of the spoon head and the width of the spoon head. The sorting discharge port 150 is provided with a first baffle plate 160 near the output side of the spoon of the sauce dishes to be screened, and the sorting discharge port 150 is provided with a sorting inclined surface 151 along the moving direction of the spoon of the sauce dishes to be screened. The arrangement of the first baffle plate 160 and the sorting inclined surface 151 allows the spoon of the sauce dishes to be screened to be smoothly transported to the spacing component 200, while the spoon head or the handle of the spoon always enters the spacing component 200 first.

[0025] In a specific embodiment, reference Figure 3 and Figure 4 ,in, Figure 3 A structural stereogram showing a spacing component and a screening component of a screening device for a dish spoon according to a specific embodiment of the present invention is shown. Figure 4 FIG. 2 shows a top view of a screening assembly according to a specific embodiment of the present invention. Figure 3 and Figure 4As shown, the spacing assembly 200 includes a second conveyor belt 220, guide plates 210 and a second baffle plate 230 arranged on both sides of the second conveyor belt 220. The second conveyor belt 220 is a high-speed conveyor belt, and the speed of its conveying surface is greater than the speed of the conveying surface of the first conveyor belt and the component speed of the guide transmission surface of the third guide transmission member 130 along the conveying direction a. Specifically, it can be set to a range of 400-430 mm / s, that is, the spacing between the spoons of the sauce dishes to be screened arranged in a row is widened, so that they can enter the screening assembly 300 individually to ensure the screening effect. The guide plate 210 is arranged at the lower end of the sorting inclined surface 151, and the maximum diameter between the guide plates 210 is greater than the distance from the sorting outlet 150 to the first baffle plate 160. The guide plates 210 on both sides are inclined toward the second conveyor belt 220, so that the spoon of the dish to be screened that falls on the guide plate 210 can slide into the second conveyor belt 220. The second baffle plate 230 is fixedly arranged at the rear end of the guide plate 210 to prevent the spoon of the dish to be screened from rushing out of the conveying area of ​​the spacing assembly 200 due to the too fast speed of the conveying surface of the second conveyor belt 220. The end of the second conveyor belt 220 forms a spacing discharge port 240, and the spacing discharge port 240 is provided with a spacing inclined surface 241 along the conveying direction of the second conveyor belt 220. The downstream of the spacing inclined surface 241 is provided with an inclined and rotatable buffer plate 310. The spoon of the dish to be screened passes through the transition buffer of the spacing inclined surface 241 and the buffer plate 310, so that the spoon of the dish to be screened can slide smoothly onto the two conveyor belts 340. The screening assembly 300 includes a transmission wheel assembly 350 mounted on a base and two parallel transmission belts 340. The transmission belts 340 are respectively mounted on both sides of the transmission wheel assembly 350, and a hollow space is formed in the middle that is larger than the width of the spoon head and smaller than the maximum diameter of the flavor dish, so that the spoons of the flavor dishes to be screened arranged in a straight line and spaced apart enter the screening assembly 300 through the buffer plate 310, and the hollow space between the two transmission belts 340 is used to make the spoons fall from the middle to the third conveyor belt 330 for transportation to the next process, and the flavor dishes are transported downward to the next process under the limit of the limit plates 320 on both sides. Preferably, the width of the limit plates 320 on both sides is larger than the maximum diameter of the flavor dish, and can be set to 60mm-100mm, which can be set specifically according to the size of the flavor dishes to be screened.

[0026] Preferably, the conveyor is a round belt conveyor, although Figure 4 Only two round belt conveyors are shown, but three, four, etc. round belt conveyors can be provided, as long as the spacing between two adjacent round belt conveyors is greater than the width of the spoon head and less than the maximum diameter of the saucer, so as to meet the setting of multiple groups of sorting components and spacing components and improve the screening efficiency.

[0027] Obviously, those skilled in the art can make various modifications and changes to the embodiments of the present invention without departing from the spirit and scope of the present invention. In this way, if these modifications and changes are within the scope of the claims of the present invention and their equivalents, the present invention is also intended to cover these modifications and changes. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are recorded in mutually different dependent claims does not indicate that the combination of these measures cannot be used to profit. Any reference numerals in the claims should not be considered to limit the scope.
