Description

具有紫外光檢測功能之咖啡豆檢測機Coffee bean detector with UV detection function

本創作係與咖啡豆之檢測技術有關，特別是關於一種可快速篩選咖啡豆且具有紫外光檢測功能之咖啡豆檢測機。This creation is related to the detection technology of coffee beans, especially a coffee bean detection machine that can quickly screen coffee beans and has the function of ultraviolet light detection.

咖啡豆在進行烘焙之前，普遍都會進行分級與篩選之步驟，分級之步驟是將咖啡生豆依其外觀大小分成不同等級，使得同一等級之咖啡豆在品質上有一致性，而篩選之步驟則是要剃除異物以及瑕疵豆，詳而言之，咖啡生豆在從採收、乾燥處理、脫殼、運送至儲存等環節皆可能會產生瑕疵豆，例如有破碎、發黑、蟲蛀、發霉、未熟、萎縮等等瑕疵之咖啡生豆，有明顯色彩瑕疵之瑕疵豆以及異物可利用色選機（例如我國專利編號732015所提供者）去除，但有其他細部瑕疵之瑕疵豆則通常倚賴人工進行選別。Before the coffee beans are roasted, the steps of grading and screening are generally carried out. The step of grading is to divide the green coffee beans into different grades according to their appearance size, so that the coffee beans of the same grade are consistent in quality. It is to shave off foreign objects and defective beans. To be more specific, green coffee beans may have defective beans during the process of harvesting, drying, shelling, transportation and storage, such as broken, blackened, moth-eaten, etc. Green coffee beans with defects such as moldy, underripe, shrinking, etc., and defective beans with obvious color defects and foreign matter can be removed by a color sorter (such as the one provided by my country Patent No. 732015), but defective beans with other detailed defects are usually relied on. Manual selection.

雖然目前已有篩選瑕疵豆之自動化篩選機，例如我國專利編號M570428以及M583944所提供者，但其實用性仍有不足之處，詳而言之，M570428所提供之選豆裝置的送料機構無法避免咖啡豆相互堆疊並且容易使咖啡豆彼此過於鄰近，如此之情況不但會對影像辨識作業造成阻礙，也容易發生正常豆與瑕疵豆一併被剃除之情況，而M583944所提供之咖啡豆篩選系統為了避免前述問題，係採用可讓咖啡豆有先後順序地被傳送之入料機構，並讓咖啡豆由入料機構傳送至持續轉動的轉盤上進而進行影像辨識，然而，如此之方式不但入料過於緩慢，轉盤也不能轉得太快以避免其離心力讓咖啡豆無法穩定地停留在轉盤上，因此具有檢測效率不佳之缺點。Although there are existing automatic screening machines for screening defective beans, such as those provided by Chinese patent numbers M570428 and M583944, their practicability is still insufficient. In detail, the feeding mechanism of the bean selection device provided by M570428 cannot be avoided. The coffee beans are stacked on each other and it is easy to make the coffee beans too close to each other. This situation will not only hinder the image recognition operation, but also easily cause the normal beans and defective beans to be shaved together. The coffee bean screening system provided by M583944 In order to avoid the aforementioned problems, a feeding mechanism that allows the coffee beans to be sent in sequence is used, and the coffee beans are transferred from the feeding mechanism to the continuously rotating turntable for image recognition. However, this method not only feeds the coffee beans If it is too slow, the turntable cannot be rotated too fast to avoid the centrifugal force of the coffee beans making it impossible for the coffee beans to stay on the turntable stably, so it has the disadvantage of poor detection efficiency.

此外，當咖啡生豆受到細菌入侵，造成其所含之化學物質產生變化，導致咖啡豆變質，不但對咖啡風味會有顯著的影響，更有害人體健康，因此也被精品咖啡協會（Specialty Coffee Association；簡稱SCA）列為需要剃除之咖啡瑕疵豆，但此種瑕疵豆在日常可見光下卻無法辨識，因此前述習用之咖啡豆篩選機亦無法檢測出此種瑕疵豆，而有待改進。In addition, when green coffee beans are invaded by bacteria, the chemical substances contained in them will change, resulting in the deterioration of coffee beans, which will not only have a significant impact on coffee flavor, but also be harmful to human health. ; SCA for short) is listed as the defective coffee beans that need to be shaved, but such defective beans cannot be identified under daily visible light, so the conventional coffee bean screening machine can not detect such defective beans, and needs to be improved.

有鑑於上述缺失，本創作之主要目的在於提供一種咖啡豆檢測機，係能快速且有效地篩選咖啡豆，並且具有紫外光檢測功能而能檢測出變質之咖啡豆。In view of the above deficiencies, the main purpose of this creation is to provide a coffee bean detection machine, which can quickly and effectively screen coffee beans, and has an ultraviolet light detection function to detect deteriorated coffee beans.

為達成上述目的，本創作所提供之咖啡豆檢測機包含有一供料裝置、一輸送裝置、複數影像擷取單元，以及一篩選裝置。該供料裝置具有一用以容置多個咖啡豆的儲料空間，以及一與該儲料空間連通以輸出其中之咖啡豆的出料口。該輸送裝置包含有一輸送帶，該輸送帶具有沿一輸送路徑排列之多個容置孔，各該容置孔具有一用以供一該咖啡豆進入之開口，各該容置孔係僅能容置一該咖啡豆且係沿該輸送路徑移動而依序經過一入料區、一檢測區以及一篩選區，該供料裝置之出料口係朝向位於該入料區之容置孔，該檢測區具有複數檢測位置。各該影像擷取單元包含有一朝向位於該檢測區之容置孔的開口拍攝之第一影像擷取裝置、一與該第一影像擷取裝置朝向相反方向地透過一透明擋板拍攝位於該檢測區之容置孔的第二影像擷取裝置，以及提供該第一影像擷取裝置及該第二影像擷取裝置拍攝所需之光線的至少一光源，該等影像擷取單元中包含至少一可見光影像擷取單元以及至少一紫外光影像擷取單元，該可見光影像擷取單元之該至少一光源的光線為可見光，該紫外光影像擷取單元之該至少一光源的光線為紫外光，該等影像擷取單元係分別對應該等檢測位置，各該容置孔係沿該輸送路徑移動而經過該等檢測位置，以於每一該檢測位置受其對應之影像擷取單元拍攝。該篩選裝置係設置於該輸送裝置之篩選區，用以選擇性地使位於該篩選區之容置孔內的咖啡豆離開該輸送裝置。To achieve the above purpose, the coffee bean inspection machine provided by the present invention includes a feeding device, a conveying device, a plurality of image capturing units, and a screening device. The feeding device has a storage space for accommodating a plurality of coffee beans, and a discharge port communicating with the storage space for outputting the coffee beans therein. The conveying device includes a conveying belt with a plurality of accommodating holes arranged along a conveying path, each of the accommodating holes has an opening for a coffee bean to enter, and each of the accommodating holes can only The coffee bean is accommodated and moves along the conveying path to pass through a feeding area, a detection area and a screening area in sequence, and the discharge port of the feeding device is directed to the accommodating hole located in the feeding area, The detection zone has a plurality of detection positions. Each of the image capture units includes a first image capture device that shoots toward the opening of the receiving hole located in the detection area, and a first image capture device that faces the opposite direction to the first image capture device to capture images located in the detection area through a transparent baffle. a second image capture device in the accommodating hole of the area, and at least one light source for providing the light required by the first image capture device and the second image capture device for shooting, the image capture units include at least one A visible light image capturing unit and at least one ultraviolet image capturing unit, the light of the at least one light source of the visible light image capturing unit is visible light, the light of the at least one light source of the ultraviolet image capturing unit is ultraviolet light, the The equal image capturing units are respectively corresponding to the equal detection positions, and each of the accommodating holes moves along the conveying path and passes through the inspection positions, so that each of the detection positions is photographed by the corresponding image capturing unit. The screening device is arranged in the screening area of the conveying device, and is used for selectively making the coffee beans located in the accommodating holes of the screening area to leave the conveying device.

藉此，待篩選之咖啡豆係由供料裝置之出料口輸出至該輸送裝置之入料區並一對一地容置於位在入料區之容置孔內，然後咖啡豆隨著其所在之容置孔移動而依序經過該檢測區及該篩選區，各個容置孔內的咖啡豆在該檢測區受第一、二影像擷取裝置由二相反方向拍攝（例如第一影像擷取裝置由上往下拍攝、第二影像擷取裝置由下往上拍攝），進而供一影像分析軟體辨識出各個容置孔內為正常豆或是瑕疵豆，該篩選裝置再依據此辨識結果篩選咖啡豆，例如使正常豆離開該輸送裝置而進入正常豆儲存桶，或者使瑕疵豆離開該輸送裝置而進入瑕疵豆儲存桶。由於每一容置孔內僅能容置一咖啡豆，可避免咖啡豆因相互堆疊或過於鄰近而對影像辨識造成阻礙，因此本創作之咖啡豆檢測機可有效地篩選咖啡豆。此外，由於影像之拍攝及分析速度很快，且咖啡豆係穩定地容置於輸送裝置之容置孔內，輸送裝置之輸送速度也可以很快而不會使咖啡豆移動或掉落，因此本創作之咖啡豆檢測機可產生良好之檢測效率。再者，紫外光中的紫外線A(UVA)可以活化細胞機能，變質之咖啡豆中不當的有機物質在紫外光照射下會吸收能量並發射可見螢光，因此本創作之咖啡豆檢測機可藉由其紫外光影像擷取單元檢測出可見光（例如白光）下無法辨識之變質咖啡豆（亦稱為螢光瑕疵豆）。In this way, the coffee beans to be screened are output from the discharge port of the feeding device to the feeding area of the conveying device, and are accommodated in the accommodating holes in the feeding area one-to-one, and then the coffee beans follow the The accommodating hole where it is located moves through the detection area and the screening area in sequence, and the coffee beans in each accommodating hole are captured by the first and second image capturing devices in opposite directions in the detection area (for example, the first image The capture device shoots from top to bottom, and the second image capture device shoots from bottom to top), so that an image analysis software can identify whether the accommodating holes are normal beans or defective beans, and the screening device can then identify based on this. As a result, the coffee beans are screened, eg, normal beans leave the conveyor into a normal bean storage bin, or defective beans leave the conveyor into a defective bean storage bin. Since only one coffee bean can be accommodated in each accommodating hole, it can prevent the coffee beans from being stacked or too close to each other, which may hinder image recognition. Therefore, the coffee bean detector of the present invention can effectively screen the coffee beans. In addition, since the image capture and analysis speed is very fast, and the coffee beans are stably accommodated in the accommodating holes of the conveying device, the conveying speed of the conveying device can also be fast without causing the coffee beans to move or fall. The coffee bean testing machine of this creation can produce good testing efficiency. In addition, ultraviolet A (UVA) in ultraviolet light can activate cell function, and improper organic substances in deteriorated coffee beans will absorb energy and emit visible fluorescence under ultraviolet light irradiation, so the coffee bean detection machine of this creation can be used. Deteriorated coffee beans (also known as fluorescently defective beans) that cannot be identified under visible light (such as white light) are detected by its UV image capture unit.

The aforementioned components of the coffee bean detector 10 are actually arranged in a casing. In order to simplify the drawing and facilitate the description, the drawings in this creation do not show the complete casing, but only show the inside of the casing. It is used to provide a base plate 15 and a vertical plate 16 for the aforementioned partial components.

該輸送裝置20為一可循環輸送之輸送帶系統，係包含有一驅動馬達21、受該驅動馬達21驅轉之二滾輪22A、22B、一固定於該立板16之遮擋單元25（見圖3並詳述於下文），以及一繞設於該二滾輪22A、22B及該遮擋單元25之輸送帶23（例如食品級輸送帶）。The conveying device 20 is a circulatory conveying conveyor system, which includes a driving motor 21, two rollers 22A and 22B driven by the driving motor 21, and a shielding unit 25 fixed on the vertical plate 16 (see FIG. 3 ). and described in detail below), and a conveyor belt 23 (eg, a food-grade conveyor belt) wound around the two rollers 22A, 22B and the shielding unit 25 .

該輸送帶23具有分別位於其外側及內側之一第一表面231及一第二表面232，以及貫穿第一、二表面231、232之多個容置孔233，該等滾輪22A、22B及該遮擋單元25係抵接於該第二表面232並將該輸送帶23設置成梯形，使得該輸送帶23包含有一較短之上水平段234、一較長之下水平段235、一自該下水平段235之右端傾斜地向上延伸至該上水平段234之右端的第一傾斜段236，以及一自該上水平段234之左端傾斜地向下延伸至該下水平段235之左端的第二傾斜段237。從圖3之方向看，該等滾輪22A、22B係驅動該輸送帶23以逆時針方向循環轉動，使得各該容置孔233沿一呈梯形之輸送路徑P移動而依序經過一位於該第一傾斜段236之入料區26、一位於該上水平段234之檢測區27、一位於該第二傾斜段237之篩選區28，以及一位於該第二傾斜段237與該下水平段235之交接處的集料區29。The conveyor belt 23 has a first surface 231 and a second surface 232 located on the outer side and inner side of the conveyor belt 23 respectively, and a plurality of accommodating holes 233 penetrating the first and second surfaces 231 and 232. The rollers 22A, 22B and the The shielding unit 25 abuts on the second surface 232 and sets the conveyor belt 23 into a trapezoid shape, so that the conveyor belt 23 includes a shorter upper horizontal section 234, a longer lower horizontal section 235, and a lower horizontal section 235. The right end of the horizontal section 235 extends obliquely upward to the first inclined section 236 of the right end of the upper horizontal section 234 , and a second inclined section extends obliquely downward from the left end of the upper horizontal section 234 to the left end of the lower horizontal section 235 237. Viewed from the direction of FIG. 3 , the rollers 22A, 22B drive the conveyor belt 23 to rotate in a counterclockwise direction, so that each of the accommodating holes 233 moves along a trapezoidal conveying path P and sequentially passes through a A feeding area 26 in the inclined section 236 , a detection area 27 in the upper horizontal section 234 , a screening area 28 in the second inclined section 237 , and a second inclined section 237 and the lower horizontal section 235 The aggregate area 29 at the junction.

值得一提的是，本創作之圖式僅繪製出位於該輸送帶23之上水平段234的容置孔233，實際上該輸送帶23係以如同上水平段234之容置孔233的分佈方式在整體各段皆設有容置孔233。該等容置孔233係沿該輸送路徑P排成三行及多列，亦即每一列包含有三容置孔233，同一列之容置孔233係同時移動至該入料區26、該檢測區27、該篩選區28或該集料區29之同一位置。It is worth mentioning that the drawing of this creation only draws the accommodating holes 233 located on the horizontal section 234 above the conveyor belt 23 . In fact, the conveyor belt 23 has the same distribution as the accommodating holes 233 of the horizontal section 234 above. There are accommodating holes 233 in each section of the whole. The accommodating holes 233 are arranged in three rows and multiple rows along the conveying path P, that is, each row includes three accommodating holes 233, and the accommodating holes 233 in the same row are simultaneously moved to the feeding area 26, the detection zone 27, the screening zone 28 or the same location of the aggregate zone 29.

如圖3所示，該遮擋單元25包含有多個固定於該立板16之固定件256，以及藉由固定於該等固定件256而緊鄰於該輸送帶23之第二表面232的一入料區遮擋件251、一檢測區遮擋件252以及一篩選區遮擋件253，該入料區遮擋件251係設於該輸送帶23之第二表面232位於該入料區26的部分，該檢測區遮擋件252係設於該輸送帶23之第二表面232位於該檢測區27的部分，該篩選區遮擋件253係設於該輸送帶23之第二表面232位於該篩選區28的部分。如圖4所示，各該容置孔233具有分別位於該輸送帶23之第一、二表面231、232之二開口233a、233b，各該容置孔233之開口233a在各個位置皆未被遮擋而呈開放狀態，而各該容置孔233之開口233b在從入料區26移動至檢測區27及篩選區28的過程中係受入料區遮擋件251、檢測區遮擋件252及篩選區遮擋件253遮擋。As shown in FIG. 3 , the shielding unit 25 includes a plurality of fixing pieces 256 fixed to the vertical plate 16 , and an entry point close to the second surface 232 of the conveyor belt 23 by being fixed on the fixing pieces 256 . A material area cover 251, a detection area cover 252 and a screening area cover 253, the feed area cover 251 is arranged on the part of the second surface 232 of the conveyor belt 23 located in the material input area 26, the detection area The area shielding member 252 is installed on the portion of the second surface 232 of the conveyor belt 23 located in the detection area 27 , and the screening area shielding member 253 is installed on the portion of the second surface 232 of the conveyor belt 23 located in the screening area 28 . As shown in FIG. 4 , each of the accommodating holes 233 has two openings 233a and 233b respectively located on the first and second surfaces 231 and 232 of the conveyor belt 23 , and the openings 233a of each of the accommodating holes 233 are not closed at various positions. The openings 233b of the accommodating holes 233 are in the process of moving from the feeding area 26 to the detection area 27 and the screening area 28 are blocked by the feeding area shielding member 251, the detection area shielding member 252 and the screening area. The shielding member 253 shields.

如圖1所示，該供料裝置30包含有一概呈漏斗狀之供料器31，以及一設置於該供料器31之節流閥32，該供料器31具有一用以容置大量待篩選之咖啡豆（咖啡生豆）的儲料空間311，以及一與該儲料空間311連通且位於該儲料空間311之下方的出料口312，該出料口312係朝向輸送帶23位於該入料區26之容置孔233的開口233a，藉此，該儲料空間311內之咖啡豆可落下而由該出料口312輸出至該輸送裝置20之入料區26，由於各該容置孔233在從入料區26移動至檢測區27及篩選區28的過程中係呈上開放且下封閉之狀態，因此咖啡豆在前述過程中係持續位於容置孔233內而不會掉落。該節流閥32係設於該儲料空間311與該出料口312之間，用以控制該儲料空間311內之咖啡豆落下之數量，藉以限制咖啡豆自該出料口312輸出之速率。此外，該入料區遮擋件251上更固定一由多個板體構成之側擋單元24，以將位於該入料區26之容置孔233的開口233a包圍在該側擋架29內部，藉以將該供料裝置30輸出之咖啡豆限制在該入料區26。As shown in FIG. 1 , the feeding device 30 includes a generally funnel-shaped feeder 31 , and a throttle valve 32 disposed in the feeder 31 . The feeder 31 has a A storage space 311 for the coffee beans to be screened (green coffee beans), and a discharge port 312 that communicates with the storage space 311 and is located below the storage space 311 , and the discharge port 312 faces the conveyor belt 23 The opening 233a of the accommodating hole 233 is located in the feeding area 26, whereby the coffee beans in the storage space 311 can be dropped and output from the discharging port 312 to the feeding area 26 of the conveying device 20. The accommodating hole 233 is in a state of being open at the top and closed at the bottom during the process of moving from the feeding area 26 to the detection area 27 and the screening area 28, so the coffee beans are continuously located in the accommodating hole 233 during the aforesaid process without will fall. The throttle valve 32 is disposed between the storage space 311 and the discharge port 312 to control the amount of coffee beans falling in the storage space 311 , so as to limit the amount of coffee beans output from the discharge port 312 . rate. In addition, a side blocking unit 24 composed of a plurality of plates is further fixed on the feeding area shielding member 251, so as to enclose the opening 233a of the accommodating hole 233 of the feeding area 26 inside the side blocking frame 29, Thereby, the coffee beans output from the feeding device 30 are restricted to the feeding area 26 .

如圖4所示，各該容置孔233之開口233a僅能供一該咖啡豆17進入，且各該容置孔233之內部空間僅能容置一該咖啡豆17，進一步而言，各該容置孔233的深度d1係以大於或等於一該咖啡豆17之高度h的1倍且小於一該咖啡豆17之高度h的2倍（亦即2h＞d1＞1h）為較佳之設計，如此可使得咖啡豆17穩定地受容置孔233之內壁推動而順利地受該輸送裝置20輸送，而又不足以讓二顆相互堆疊之咖啡豆完全容置於同一容置孔233內。As shown in FIG. 4 , the opening 233a of each accommodating hole 233 can only accommodate one coffee bean 17 , and the inner space of each accommodating hole 233 can only accommodate one coffee bean 17 . The depth d1 of the accommodating hole 233 is preferably greater than or equal to 1 times the height h of the coffee beans 17 and less than 2 times the height h of the coffee beans 17 (ie, 2h>d1>1h). , so that the coffee beans 17 can be stably pushed by the inner wall of the accommodating hole 233 and smoothly transported by the conveying device 20 , but not enough for two stacked coffee beans to be completely accommodated in the same accommodating hole 233 .

為了更進一步地避免有咖啡豆堆疊之情況，該入料區26更設置該掃料裝置40，如圖1所示，該掃料裝置40係位於該供料裝置30之出料口312與該檢測區27之間且包含有一毛刷41及二掃料滾輪42、43，該毛刷41與該輸送帶23之第一表面231僅相隔一微小之預定距離d2（如圖4所示），因此可將凸出於該容置孔233之開口233a超過該預定距離d2之咖啡豆17掃落，以確保該輸送帶23之每個容置孔233內只有一顆咖啡豆17，該二掃料滾輪42、43則剛好抵靠於該輸送帶23之第一表面231，並朝相反方向轉動而分別向上及向下地將咖啡豆17更撥進容置孔233。容置於該入料區26之容置孔233內的咖啡豆隨著容置孔233移動而離開該入料區26，進而往該檢測區27移動。In order to further avoid the situation of stacking coffee beans, the feeding area 26 is further provided with the sweeping device 40 , as shown in FIG. 1 , the sweeping device 40 is located between the discharge port 312 of the feeding device 30 and the A brush 41 and two sweeping rollers 42 and 43 are included between the detection areas 27. The brush 41 is only separated from the first surface 231 of the conveyor belt 23 by a small predetermined distance d2 (as shown in FIG. 4 ). Therefore, the coffee beans 17 protruding from the opening 233a of the accommodating hole 233 beyond the predetermined distance d2 can be swept off to ensure that there is only one coffee bean 17 in each accommodating hole 233 of the conveyor belt 23 . The feed rollers 42 and 43 just abut against the first surface 231 of the conveyor belt 23 and rotate in opposite directions to push the coffee beans 17 upward and downward respectively into the accommodating holes 233 . The coffee beans accommodated in the accommodating hole 233 of the feeding area 26 leave the feeding area 26 along with the movement of the accommodating hole 233 , and then move toward the detection area 27 .
