Description

咖啡豆檢測機Coffee Bean Testing Machine

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之咖啡豆檢測機。This creation is related to the detection technology of coffee beans, especially about a coffee bean detection machine that can quickly filter coffee beans.

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 roasting coffee beans, 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, and the screening step is It is to shave off foreign bodies and defective beans. In detail, green coffee beans may have defective beans from harvesting, drying, shelling, transportation to storage, etc., such as broken, blackened, moth-eaten, Green coffee beans that are moldy, immature, shriveled, etc., have obvious color defects, and foreign objects can be removed using a color sorter (such as those provided by China Patent No. 732015), but defective beans with other detailed defects usually rely on Select manually.

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 currently automatic screening machines for screening defective beans, such as those provided by China's patent numbers M570428 and M583944, their practicality is still insufficient. In detail, the feeding mechanism of the bean selection device provided by M570428 cannot be avoided Coffee beans are stacked on top of each other and it is easy to make the coffee beans too close to each other, which not only hinders the image recognition operation, but also easily causes 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 coffee beans to be transferred sequentially is used, and the coffee beans are transferred from the feeding mechanism to a continuously rotating turntable for image recognition, however, this method not only feeds If it is too slow, the turntable cannot turn too fast to avoid the centrifugal force that prevents the coffee beans from stably staying on the turntable, so it has the disadvantage of poor detection efficiency.

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。In view of the above deficiencies, the main purpose of this creation is to provide a coffee bean testing machine that can quickly and effectively screen 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、至少一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，以及一實質上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，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。In order to achieve the above purpose, the coffee bean inspection machine provided by this creation includes a feeding device, a conveying device, at least one image capturing unit and a screening device. The feeding device has a container for accommodating a plurality of coffee beans The storage space and an outlet that communicates with the storage space to output the coffee beans therein. The conveying device includes a conveying belt having a plurality of accommodating holes arranged along a conveying path, each of which contains The placing hole has an opening for the coffee beans to enter. Each receiving hole can only accommodate one coffee bean and moves along the conveying path to sequentially pass through a feeding area, a detecting area and a In the screening area, the discharge opening of the feeding device is oriented toward the receiving hole located in the feeding area, and the image capturing unit includes a first image capturing device photographed toward the opening of the receiving hole located in the detection area, And a second image capturing device that captures the second image capturing device located in the receiving hole of the detection area through a transparent baffle substantially in the opposite direction to the first image capturing device, the screening device is disposed in the screening area of the conveying device For selectively leaving the coffee beans in the accommodating holes of the screening area from 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。In this way, the coffee beans to be screened are output from the feeding port of the feeding device to the feeding area of the conveying device and are placed one-to-one in the receiving holes in the feeding area, and then the coffee beans follow The accommodating hole in which it moves 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 from the two opposite directions in the detection area (such as the first image The capturing device is shot from top to bottom, and the second image capturing device is shot from bottom to top), and then an image analysis software is used to identify whether each receiving hole is a normal bean or a defective bean. As a result, coffee beans are screened, for example, to leave normal beans out of the conveyor and enter the normal bean storage barrel, or to leave defective beans out of the conveyor and into the defective bean storage barrel. Since only one coffee bean can be accommodated in each accommodating hole, the coffee beans can be prevented from hindering the image recognition due to stacking or being too close to each other. Therefore, the coffee bean inspection machine of this invention can effectively filter coffee beans. In addition, The imaging and analysis speed of the image 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 moving or falling the coffee beans. The coffee bean detector can produce good detection efficiency.

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驅轉之四驅動滾輪22、一繞設於該四驅動滾輪22之輸送帶23（例如食品級輸送帶）、用以調整該輸送帶23之張力的二張力調整輪24，以及一遮擋單元25。The conveying device 20 is a cyclically conveyable conveyor belt system, which includes a driving motor 21, four driving rollers 22 driven by the driving motor 21, and a conveyor belt 23 (such as foodstuffs) wound around the four driving rollers 22 Conveyor belt), two tension adjusting wheels 24 for adjusting the tension of the conveyor belt 23, and a 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，該等驅動滾輪22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，該等驅動滾輪22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以及一位於該第二傾斜段237之篩選區28。如圖1及圖2所示，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或該篩選區28之同一位置。The conveyor belt 23 has a first surface 231 and a second surface 232 located on the outside and inside thereof, respectively, and a plurality of accommodating holes 233 penetrating the first and second surfaces 231, 232, the driving rollers 22 abut On the second surface 232, the conveyor belt 23 is arranged in a trapezoidal shape, so that the conveyor belt 23 includes a shorter upper horizontal section 234, a longer lower horizontal section 235, and a slope from the right end of the lower horizontal section 235 A first inclined section 236 extending upward to the right end of the upper horizontal section 234, and a second inclined section 237 extending obliquely downward from the left end of the upper horizontal section 234 to the left end of the lower horizontal section 235. From the direction of FIG. 3, the driving rollers 22 drive the conveyor belt 23 to rotate in a counterclockwise direction, so that each accommodating hole 233 moves along a trapezoidal conveying path P and sequentially passes a The feeding area 26 of the inclined section 236, a detection area 27 located in the upper horizontal section 234, and a screening area 28 located in the second inclined section 237. As shown in FIG. 1 and FIG. 2, the accommodating holes 233 are arranged in three rows and multiple columns along the conveying path P, that is, each column includes three accommodating holes 233, and the accommodating holes 233 of the same row move simultaneously To the same position of the feeding area 26, the detection area 27 or the screening area 28.

如圖3所示，該遮擋單元25包含有一入料區遮擋件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、篩選區遮擋件253或該輸送裝置之其他構件（例如驅動滾輪22）遮擋。As shown in FIG. 3, the shielding unit 25 includes a feed area shield 251, a detection area shield 252 and a screening area shield 253. The feed area shield 251 is disposed on the second side of the conveyor belt 23 The surface 232 is located at the part of the feeding zone 26, the detection zone shield 252 is located at the portion of the conveyor belt 23, the second surface 232 is located at the detection zone 27, the screening zone shutter 253 is located at the conveyor belt 23 The second surface 232 is located in the screening area 28. As shown in FIG. 4, each of the accommodating holes 233 has two openings 233 a and 233 b respectively located on the first and second surfaces 231 and 232 of the conveyor belt 23, and the opening 233 a of each of the accommodating holes 233 is unavailable at various positions The opening 233b of each accommodating hole 233 is received by the blocking member 251 of the feeding area, the blocking member 252 of the detecting area, and the screening area during the movement from the feeding area 26 to the detection area 27 and the screening area 28 The blocking member 253 or other components of the conveying device (such as the driving roller 22) block.

如圖2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。As shown in FIG. 2, the feeding device 30 includes a feeder 31 having a substantially funnel shape, and a throttle valve 32 provided on the feeder 31. The feeder 31 has a A storage space 311 of coffee beans (coffee beans) to be screened, and a discharge opening 312 communicating with the storage space 311 and located below the storage space 311, the discharge opening 312 is oriented toward the inlet The opening 233a of the accommodating hole 233 of the material area 26, by which the coffee beans in the storage space 311 can fall down and output from the material outlet 312 to the material input area 26 of the conveying device 20, The hole 233 moves upward from the feeding area 26 to the detection area 27 and the screening area 28, and the bottom is closed. Therefore, the coffee beans remain in the receiving hole 233 during the foregoing process without falling . 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, thereby limiting the output of coffee beans from the discharge port 312 rate.

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係以實質上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 233 a of each accommodating hole 233 can only enter one coffee bean 17, and the internal space of each accommodating hole 233 can only accommodate one coffee bean 17. Further, each The depth d1 of the receiving hole 233 is substantially greater than or equal to 1 times the height h of a coffee bean 17 and less than 2 times the height h of a coffee bean 17 (that is, 2h>d1>1h) A good design, so that the coffee beans 17 can be stably pushed by the inner wall of the accommodating hole 233 and smoothly conveyed by the conveying device 20, but it is not enough to allow two coffee beans stacked on top of each other to be completely accommodated in the same accommodating hole 233 Inside.

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，在本實施例中，該掃料裝置40包含有二毛刷41，各該毛刷41係位於該供料裝置30之出料口312與該檢測區27之間，且各該毛刷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，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。In order to further avoid the situation where coffee beans are stacked, the feeding area 26 is further provided with the sweeping device 40. In this embodiment, the sweeping device 40 includes two brushes 41, each of which is located in the Between the discharge port 312 of the feeding device 30 and the detection area 27, and each brush 41 and the first surface 231 of the conveyor belt 23 are only separated by a tiny predetermined distance d2, so that The coffee beans 17 with the opening 233a of the placing hole 233 exceeding the predetermined distance d2 are swept down to ensure that there is only one coffee bean 17 in each receiving hole 233 of the conveyor belt 23.

請參閱圖5，該輸送裝置20可更包含有一設置於該入料區26且位於該輸送帶23之第一表面231的側擋架29，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。詳而言之，該側擋架29包含有實質上分別位於該輸送帶23二側之二側板291，以及連接於該二側板291之間的一前板292及一後板293，該前板292及該後板293分別設有鄰接於該輸送帶23之第一表面231的一輸送開口294（如圖1所示）及一排料口295。藉此，該側擋架29可發揮相當之遮擋效果而將該供料裝置30輸出之咖啡豆限制在該入料區26，由於該輸送帶23位於該入料區26的部分係沿該輸送路徑P由下而上傾斜，該供料裝置30輸出至該入料區26的咖啡豆若未能掉入該輸送裝置20之容置孔233則會自然向下傾斜滾落而經由該排料口295離開該入料區26，進而掉入位於該第一傾斜段236下方的餘料儲存桶11，待該供料裝置30內的咖啡豆皆已掉落之後，該餘料儲存桶11內的咖啡豆可再倒入該供料裝置30。而容置於該入料區26之容置孔233內的咖啡豆則隨著容置孔233移動而經由該輸送開口294離開該入料區26，進而往該檢測區27移動。Please refer to FIG. 5, the conveying device 20 may further include a side stop frame 29 disposed on the first surface 231 of the conveyor belt 23 in the feeding area 26 to receive the receiving hole 233 in the feeding area 26 The opening 233a surrounds the inside of the side frame 29. In detail, the side frame 29 includes two side plates 291 that are substantially located on both sides of the conveyor belt 23, and a front plate 292 and a rear plate 293 connected between the two side plates 291. The front plate 292 and the rear plate 293 are respectively provided with a conveying opening 294 (as shown in FIG. 1) and a discharge opening 295 adjacent to the first surface 231 of the conveying belt 23. Thereby, the side blocking frame 29 can exert a considerable shielding effect and limit the coffee beans output by the feeding device 30 to the feeding area 26, because the portion of the conveyor belt 23 located in the feeding area 26 is conveyed along the The path P inclines from bottom to top. If the coffee beans output by the feeding device 30 to the feeding area 26 fail to fall into the accommodating hole 233 of the conveying device 20, they will naturally roll down and pass through the discharge The port 295 leaves the feeding area 26, and then falls into the remaining material storage barrel 11 located below the first inclined section 236. After all the coffee beans in the feeding device 30 have fallen, the remaining material storage barrel 11 The coffee beans can be poured into the feeding device 30 again. The coffee beans accommodated in the accommodating hole 233 of the feeding area 26 leave the feeding area 26 through the conveying opening 294 as the accommodating hole 233 moves, and then move toward the detection area 27.
