  However, especially when the fruits and vegetables are grapes, the quality (sugar content) may be different due to different parts such as both ends and the center. Therefore, there has been a problem in that, if the sugar content at one point of the cocoon is only measured, if the measurement site has reached the desired sugar content, even if the measurement site contains a site that does not reach the desired sugar content, it is not excluded. That is, while it is desired that the entire cocoon has reached the desired sugar content, there has been a problem that it is not possible to remove the cocoon containing a portion that has not reached the desired sugar content.

  The present invention has been made to solve the above-described problems, and provides a koji sorting device that can exclude koji containing a portion having a low sugar content.

A sugar content measurement part calculates | requires the sugar content of an edge part and a specific site | part, when one edge part of a cocoon and the other specific site | part pass a sugar content measurement area | region.

  According to the koji sorting device of the present invention, the sugar content measuring unit can measure the sugar content at at least two places, one end of the koji and the other specific part. At this time, it is possible to measure the sugar content of at least one end of the cocoon, which is generally considered to have a low sugar content. As a result, even if the sugar content varies depending on the part, the sugar content is measured at multiple parts including the part that is thought to have a low sugar content, so excluding the part containing the part that does not reach the desired sugar content. can do. In addition, the cocoon in this invention is a crop which has a rhizome or root which becomes the edible which stored starchy material and enlarged, for example, a sweet potato, a potato, a taro, a yam, a yam, etc. are mentioned.

  As shown in FIG. 1, a sub-conveyor 70 is provided in the downstream portion of the conveyor 10 in parallel with the conveyor 10. Similar to the conveyor 10, the sub-conveyor 70 has a width that is more than the width at which one bag P can be placed and can be transported at a constant speed in one direction without falling down. Any conveyor can be used. In the present embodiment, a conveyor is used in which an endless belt is bridged between a drive shaft and a driven shaft that are arranged apart from each other. In the downstream portion of the conveyor 10, there is an opening 11a in which the side wall 11 is not provided, and the basket P can be moved from the conveyor 10 to the sub-conveyor 70 through the opening 11a.

One end of the arm 52 is rotatably attached to the end of the push rod 512, and the other end is rotatably attached to the outer peripheral portion of the drive unit 53. As the drive unit 53 rotates, the arm 52 reciprocates the pushing member 51. That is, when the end portion 52a attached to the drive unit 53 of the arm 52 is on the side away from the conveyor 10 (the state of FIG. 5), the pushing member 51 does not protrude on the conveyor 10. When the end 52a of the arm 52 is on the conveyor 10 side (the state shown in FIG. 6), the pushing member 51 protrudes on the conveyor 10.

  FIG. 13 is a block diagram illustrating the configuration of the koji sorting device 1 including the sugar content measuring device 30. The control device 40 is configured by a computer, has a CPU as a main body for controlling and calculating, and includes a storage device (not shown). The control device 40 takes in signals, data, and the like by the wrinkle detection sensor 19, the length measurement unit 60, and the sugar content measurement unit 33, executes predetermined calculation and processing, and the operations of the light projecting unit 31 and the light receiving unit 32, and The operation of the sorting device 50 is controlled. 14 and 15 show the flow of control of the koji sorting process by the control device 40, and FIG. 16 shows the flow of the sugar content measurement process by the sugar content measuring unit 30. FIG. 17 (a) shows a state in which the sugar content of a large cocoon is being measured, and FIG. 17 (b) shows a state in which the sugar content of a small cocoon is being measured. Hereinafter, with reference to FIGS. 1-17, the sorting method of the basket sorting apparatus 1 which concerns on this invention is demonstrated.

  First, as shown in FIG. 3, the holding unit 21 of the supply mechanism 20 is put into the water tank 2 in which a plurality of washed baskets P are stored. At this time, the supply mechanism 20 is in a state where the first holding member 211 and the second holding member 212 are opened. Since the inside of the water tank 2 is inclined toward the supply mechanism 20, there are a plurality of bottles P in the vicinity of the holding portion 21. As shown in FIG. 4, by driving the motor 216 to close the first holding member 211 and the second holding member 212, the curved surface 211 c of the first holding member 211 and the curved surface 212 b of the second holding member 212 A plurality (two in FIG. 4) of ridges P are held in a row in the horizontal direction. At this time, since water is stretched in the water tank 2, buoyancy acts on the ridge P. Thereby, a part of the ridge P is held in the hollow portion of the holding portion 21 by a slow operation, and the other ridge P may float in the water tank 2 so as to avoid the holding portion 21 by a slow operation. Therefore, the ridges P are held in the holding portion 21 in a line in a horizontal direction without being damaged. In this state, by winding the wire 24, the holding portion 21 contacts the lower surface of the carriage 22 as shown in FIG.

  When the pinion gear 221 is driven in this state, the pinion gear 221 rolls while meshing on the rack 232, and the holding unit 21 is moved onto the conveyor 10 as shown in FIG. Thereafter, as shown in FIG. 9, the wire 24 is extended, the holding portion 21 is brought closer to the conveyor 10, and the first holding member 211 and the second holding member 212 are opened as shown in FIG. (2 pieces in FIG. 10) are supplied on the conveyor 10 in a state of being aligned in a line along the conveying direction. As shown in FIGS. 11 and 12, the supply mechanism 20 that supplies the basket P onto the conveyor 10 winds up the wire 24 while keeping the first holding member 211 and the second holding member 212 open, and the carriage 22 The holding portion 21 is brought into contact with the pinion gear 211 and the pinion gear 211 is driven to return to the upper side of the water tank 2. The holding part 21 returned to the upper side of the water tank 2 is inserted into the water tank 2 by extending the wire 24, and holds the bag P in the water tank 2. By repeating this, the supply mechanism 20 sequentially supplies the basket P on the conveyor 10.

  As shown in FIG. 2, the bag P supplied onto the conveyor 10 is conveyed to the first gate 16 by the conveyor 10. The ridges P that have reached the first gate 16 are brought close to the center C in the width direction of the conveyor 10 by the first gate 16 and pass through the first gate 16 one by one. The bag P that has passed through the first gate 16 is dried by the blower 18 while being conveyed by the conveyor 10. Then, as shown in FIGS. 2, 5, and 6, the conveyor 10 sequentially conveys the length measurement unit 60, the sugar content measurement unit 30, and the sorting mechanism 50. Thereafter, the sugar is divided according to the sugar content by the distribution mechanism 50 and is conveyed to the container 4 or the container 5 by the conveyor 10 or the sub-conveyor 70.

  Next, with reference to FIG. 14 and FIG. 15, the flow of the soot screening process in the control apparatus 40 is shown. 14 and 15 show the flow of processing for one ridge P for simplification of description, but in reality, a plurality of ridges P are successively conveyed by the conveyor 10. Needless to say, the processes shown in FIGS. 14 and 15 are executed in parallel for each bag P.

  First, in the control device 40, the CPU determines whether or not the bag P has passed through the first gate 16 based on the detection signal sent from the bag detection sensor 19 (step ST1, hereinafter “ST1”). ). Here, after the light is blocked by 芋 P, the detection signal is sent to the CPU at the timing when the light receiver of the 芋 detection sensor 19 detects the light, that is, immediately after 芋 P has passed through the first gate 16. Is being read. When it is determined that 芋 P has passed through the first gate 16 (“YES” in ST1), the CPU measures the timing for measuring the length and sugar content of 芋 P, and the timing for distributing 芋 P. T is activated (ST2).

  Next, in the control device 40, the CPU reads the length of the heel P measured by the length measuring unit 60 (ST3). In the length measuring unit 60, the sensor unit 61 irradiates the heel P with ultrasonic waves and receives the ultrasonic waves that bounce off. In the sensor unit 61, the ultrasonic wave is received while the heel P passes through the sensor unit 61. When the heel P finishes passing through the sensor unit 61, the ultrasonic wave rebounding from the heel P is not received. . The calculation unit 62 measures the time during which the sensor unit 61 is receiving the ultrasonic wave, and determines the speed V of the conveyor 10 and the time during which the ultrasonic wave is being received by the predetermined speed v. The length L is calculated. The CPU reads the calculated length L of the bag P.

  At the same time, in the control device 40, the CPU determines the predetermined speed v of the conveyor 10, the distance d2 between the wrinkle detection sensor 19 and the sugar content measuring device 30, for each wrinkle P detected by the wrinkle detection sensor 19, and From the distance d3 (see FIG. 13) between the heel detection sensor 19 and the sorting mechanism 50, the time required for each heel P to reach the sugar content measuring device 30 and the sorting mechanism 50 is calculated. Then, the CPU determines the timing Tsc at which the sugar content measuring device 30 measures the sugar content of the cocoon P from the arrival time of the cocoon P to the sugar content measuring device 30 and the distribution mechanism 50 and the length L of the cocoon P, and the distribution. The mechanism 50 calculates the timing Ttr for selecting the bag P (ST4, ST5). In this embodiment, since the rear end of the eyelid P is detected by the eyelid detection sensor 19, the sugar content measurement timing Tsc of the eyelid P is Tsc = (d2 / v) − ((L / 2) / v) = ( d2-L / 2) / v. The sorting operation timing Ttr for sorting 芋 P is calculated by Ttr = (d3 / v) − ((L / 2) / v) = (d3−L / 2) / v.

  Next, in the control device 40, the CPU determines whether or not the timer T activated at the timing when the soot P is detected has reached the sugar content measurement timing Tsc of the soot P (ST6). When the timer T determines that the sugar content measurement timing Tsc of 芋 P is reached (“YES” in ST6), the CPU measures the sugar content of 芋 P with the sugar content measurement unit 30 (ST7).

  As shown in FIG. 16, in the sugar content measurement process, first, the CPU determines whether or not the length L of the ridge P is a predetermined length, which is 7.0 cm or more in this embodiment (ST71). When it is determined that the length L of the heel P is 7.0 cm or more (“YES” in ST71), the R1, R3, and R5 light receivers 321 (see FIG. 17A) of the light receivers 321 are operated. (ST72). On the other hand, when it is determined that the length L of the ridge P is less than 7.0 cm (“NO” in ST71), the R2 and R4 light receivers 321 (see FIG. 17B) of the light receivers 321 are operated. (ST73). At the same time, the light projecting unit 31 is also operated. Thereafter, the sugar content measurement value measured by the sugar content measurement unit 30 is acquired (ST74, ST75).

  In the sugar content measurement unit 30, when the sugar content measurement process is started, light is emitted from the light projecting unit 31, and the light that has passed through the ridge P is received by the light receiver 321. At this time, as described above, when the length L of the ridge P is 7.0 cm or more, the light is received by the light receivers 321 of R1, R3, and R5 (see FIG. 17A), and the length L of the ridge P is obtained. Is less than 7.0 cm, light is received by the R2 and R4 light receivers 321 (see FIG. 17B). The light received by the light receiver 321 is analyzed by the spectroscope 331 (see FIG. 2), and an electromagnetic wave spectrum is calculated. The electromagnetic wave spectrum analyzed by the spectroscope 331 is sent to the computing unit 332 (see FIG. 2), and the computing unit 332 calculates 芋 P based on the relationship between the electromagnetic wave spectrum and the sugar content input in advance to the computing unit 332. The sugar content is calculated.

  When the sugar content measurement value is acquired from the sugar content measurement unit 30, in the control device 40, the CPU determines the degree of sugar content of the cocoon P according to the measurement value of the sugar content measured by the sugar content measurement device 30 (ST76). Specifically, the CPU compares the sugar content of each part of 芋 P with a reference sugar content inputted in advance, in this embodiment sugar content 10, and whether or not the sugar content of each part satisfies the standard sugar content. Determine whether. Here, the sugar content of each part refers to the sugar content measured by the light receiver 321 of R1, R3, and R5 when the length L of the heel P is 7.0 cm or more, and the length L of the heel P is 7.0 cm. When it is less than this, it is the sugar content measured by the light receiver 321 of R2 and R4. Then, the CPU determines that the cocoon P in which the sugar content of all the parts satisfies the standard sugar content is determined to be the cocoon that satisfies the standard sugar content, and determines the cocoon P in which the sugar content does not satisfy the standard sugar content even at one location as a reference. It is determined that the sugar content does not meet the sugar content.

  Next, in the control device 40, the CPU determines whether or not the timer T activated at the timing when the し た P is detected has reached the timing Ttr for selecting the 芋 P (ST8). When it is determined that the timer T has reached the timing Ttr for selecting 芋 P (“YES” in ST8), the CPU has insufficient sugar content of 芋 P relative to the reference sugar content based on the above determination result. It is determined whether or not (ST9). When the determination result indicates that the basket P satisfies the standard sugar content (“NO” in ST9), the CPU does not operate the sorting device 50, and the bottle P is conveyed on the conveyor 10 as it is and accommodated in the container 4. Is done. On the other hand, when the determination result indicates that と い う P does not satisfy the standard sugar content (sugar content is insufficient) (“YES” in ST9), the CPU operates the sorting device 50 (ST10). At this time, by the extrusion operation of the sorting device 50, that is, when the basket P is pushed out to the sub-conveyor 70 by the extruding member 51, the kite P gets on the sub-conveyor 70 and is transported on the sub-conveyor 70. Is housed. Thereafter, the CPU stops the timer T (ST11), and finishes the selection process for the bag P.

  As described above, in the present embodiment, the plurality of light receivers 321 are used to receive the transmitted light at two or more locations of the cocoon P, and the sugar content measurement unit 33 performs the measurement of the cocoon P based on the transmitted light. Two or more sugar levels can be measured. In the plurality of light receivers 321, the light receiver 321 used is changed depending on the length L of the collar P, and when the length L of the collar P is long, the light receivers 321 of R 1, R 3, and R 5 are used. When the length L of P is short, R2 and R4 light receivers 321 are used. Thereby, without adjusting the arrangement of the light receiver 321, the sugar content of both ends and the center can be measured accurately when at least both ends of the basket P and the length L of the basket P are long. Thus, since the sugar content of both ends of cocoon P, which is generally considered to be low in sugar content, can be measured, even cocoon P having a variation in sugar content depending on the site is excluded from cocoon P containing a portion that does not reach the desired sugar content can do.

  In addition, since the basket sorting device 1 includes the supply mechanism 20 that reciprocates between the water tank 2 and the conveyor 10 and continuously supplies the rice cake P onto the conveyor 10, the water tank 2 is filled with the basket P. Only the bowl P is continuously supplied onto the conveyor 10. Thereby, the trouble of supplying the baskets P on the conveyor 10 one by one can be saved. In addition, the holding unit 21 that holds the ridges P of the supply mechanism 20 can hold the plurality of ridges P in a row in the horizontal direction, and therefore supplies the plurality of ridges P in a row on the conveyor 10 at a time. Can do. Thereby, the space | interval of the basket P supplied on the conveyor 10 can be made into the minimum space | interval which can measure sugar content, and the processing capacity of the basket sorting apparatus 1 can be improved. Moreover, since the basket P supplied on the conveyor 10 is brought close to the center C in the width direction of the conveyor 10 by the first gate 16, it is possible to perform an accurate measurement by the length measuring unit 60 and the sugar content measuring device 30. .

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning.

  For example, in the above embodiment, the light receiving unit 32 includes five light receivers 321, but the number of light receivers 321 included in the light receiving unit 32 may be an arbitrary number. For example, when there are three light receivers 321, the first and third are used when the length L of 芋 P is long, and the second and third are used when the length L of 芋 P is short. Thus, the sugar content can be measured. For example, when there are seven light receivers 321, the first, fourth, and seventh are used when the length L of the heel P is long, and the second is used when the length L of the heel P is medium. When the fourth and sixth are used and the length L of the heel P is short, the sugar content can be measured using the third and fifth. That is, the length L of the heel P is not limited to the aspect in which the length is divided on the basis of 7.0 cm, and the length L of the heel P is based on the length criterion based on one or more arbitrary length standards. Depending on whether it is large or small, at least two light receivers 321 can be defined. In addition, the light receiver 321 to be used is not necessarily determined so as to be able to measure both ends of the ridge P, and may be determined so that at least one end and other specific parts can be measured. .

  Further, the number of the light receivers 321 provided in the light receiving unit 32 may be one, or at least one arbitrary number. When there is one light receiver 321, the sugar content measurement region 301 is equivalent to the width of the light receiver 321. That is, the sugar content measurement region 301 does not have to have a size in which the ridges P completely enter. In this case, the light receiver 321 receives the transmitted light at two locations with respect to one ridge P. That is, for example, the first transmitted light is received at the timing when the leading end (downstream end) of the cocoon P reaches the sugar content measurement region 301, and the rear end portion (upstream side) of the cocoon P is received in the sugar content measurement region 301. The transmitted light is received at two locations with respect to one ridge P by shifting the time so that the transmitted light at the second location is received at the timing when the end of the first portion arrives. That is, the light receiving unit 32 receives transmitted light when one end of one ridge P and another specific part pass through the sugar content measurement region 301, and the sugar content measuring unit 33 receives the end and Any mode can be used as long as the sugar content of the specific part can be calculated.

  Moreover, in the said embodiment, the distribution mechanism 50 provides one set of the extrusion member 51, the arm 52, and the drive part 53, drives the extrusion member 51, pushes the eaves P to the sub conveyor 70, and makes eaves P Although sorting is performed, the basket P may be sorted by any other known means. Further, the distribution mechanism 50 can also provide a plurality of sets of the extrusion member 51, the arm 52, and the drive unit 53, and distribute the baskets P according to the sugar content at a plurality of stages. In other words, the standard of sugar content for distributing cocoon P is not limited to sugar content 10, and can be any sugar content. Furthermore, even if a plurality of sugar content standards are provided and 芋 P is distributed according to a plurality of sugar content levels, Good.

  Moreover, in the said embodiment, the supply mechanism 20 has the holding | maintenance part 21 which can hold the basket P in a row, and the holding part 21 reciprocates the water tank 2 and the conveyor 10 in which the basket P is stored, and conveys it. Although the candy P is continuously supplied onto 10, the supply mechanism 20 is not limited to the above embodiment. For example, the storage tank which stores the basket P is installed on the conveyor 10, and the basket P is aligned on the conveyor 10 in a line in the conveying direction, such as a mode in which the basket P is supplied to the conveyor 10 one by one from the storage tank. As long as it is continuously supplied in such a state, any known mode can be adopted. Further, when the basket P is artificially supplied onto the conveyor 10, the supply mechanism 20 may not be provided.

  Moreover, in the said embodiment, although the basket sorting apparatus 1 is provided with the 1st gate 16, the air blower 18, and the length measurement part 60, when the basket P is previously mounted in a line at the center of the width direction of the conveyor 10, it is beforehand. These configurations are not necessarily required when the dried basket P is placed on the conveyor 10 or when the basket P having a predetermined length is flowed. When the length measuring unit 60 is not provided, the light receiver 321 to be used is not determined by detecting the length of the basket P, but is artificially received according to the length of the basket P placed on the conveyor 10. 321 may be determined.
