[Prior art]
2. Description of the Related Art In a fruit sorting apparatus, a technique using a brush roll to transfer and supply sorted fruits and the like is known.
[0003]
[Problems to be solved by the invention]
In a sorting apparatus that sorts each fruit sorting area for each weight sorting area while accurately placing and transporting fruits, vegetables, and the like to a sorting dish, it is not easy to supply one piece to the sorting dish accurately. Particularly, in the case of long sorts such as carrots and sweet potatoes, the supply posture by the brush roll is difficult to be constant. When the fruits supplied between the pair of left and right brush rollers are superimposed on each other, the transport interval is not constant. Further, the fruit tends to be sent out in the rotation direction of the brush roller, and it is difficult to maintain a stable conveyance. In order to accurately supply fruits to a sorting line such as a weight sizer, it is necessary that the fruits are transported and supplied at regular intervals and are accurately supplied to each sorting dish.
[0004]
[Means for Solving the Problems]
The invention described in claim 1 has a configuration of a conveyor for fruits or the like, characterized in that the planting inclination angles A and B of the brush 3 with respect to the roll core 2 in the brush roller 1 are gradually set in accordance with the transport direction.
When fruits are supplied to the upper surface of the valley by the rotation of the pair of left and right brush rollers 1, the fruits are transferred in the direction of the inclination of the brush 3 while undergoing the brushing action. At this time, since the conveying speed by the brush 3 with the inclination angle B is higher than the conveying speed by the brush 3 with the inclination angle A, the fruits in the superposed state at the supply start end are also aligned in a line along the valley. When it reaches the terminal end due to the speed difference, a certain space is created between the front and rear fruits. Fruit is discharged from the end of the brush roller 3 at regular intervals. When the fruit is in a long form such as a carrot, it is rotated around its longitudinal centerline and transported longitudinally forward while being brushed.
[0005]
According to the second aspect of the present invention, a sorting belt 4 for receiving and supplying fruits supplied from the brush roller 1 and sorting and discharging the fruits while transporting them is continuously provided in the same direction as the roller shaft 5 of the brush roller 1. It is characterized by the following. The fruits conveyed by the brush roller 1 are supplied one by one onto a sorting belt 4 at a constant interval at the end. The fruits conveyed in the same direction by the sorting belt 4 are sorted and discharged to a predetermined sorting position on the way. For this reason, while the fruit is being transferred from the brush roller 1 to the sorting belt 4, the fruit is conveyed while maintaining the same orientation or posture with almost no change in orientation or posture.
[0006]
According to a third aspect of the present invention, a sorting belt 4 for sorting and discharging fruits while receiving and transporting them is stretched in a triangular form by front and rear pulleys 6 and 7 and an intermediate pulley 8 at an intermediate lower portion. The side wall frame 9 is formed with a conveyor 10 for fruit or the like, characterized in that an interval 10 is formed along the lower side of the sorting belt 4 so that the sorting belt 4 can be moved in and out of the side.
The sorting belt 4 sorts and discharges the fruits to the side each time the fruits are sorted while the fruits conveyed and supplied from the brush roller 1 are placed and conveyed as described above. The upper side of the sorting belt 4 is stretched substantially horizontally, and the lower side thereof is stretched downward by the intermediate pulley 7 and wound in a triangular shape. When the sorting belt 4 is attached or detached for replacement or the like, the lower side of the sorting belt 4 wound in a triangular shape along the gap 10 of the side wall frame 9 is taken in and out from the side.
[0007]
【The invention's effect】
According to the first aspect of the present invention, the fruit conveyed along the direction of the brush roller 1 is conveyed one after another by a speed difference during the conveyance by the brush roller 1, and is conveyed one by one at a constant interval between the front and rear fruits. Is caused, and the feeding of each piece can be smoothly and accurately performed with a simple configuration.
[0008]
According to the second aspect of the present invention, since the conveying direction by the brush roller 1 and the conveying direction by the selection belt 4 are set substantially in a straight line in the same direction, the step of conveying and inheriting the fruits can be reduced, and these conveying steps can be performed. And succession and the like can be performed smoothly. In addition, the transporting process can be shortened, the configuration can be simplified, the apparatus as a whole can be downsized, and the installation site can be narrowed.
[0009]
According to the third aspect of the present invention, the selection belt 4 is stretched in a triangular form by the front and rear pulleys 6 and 7 and the intermediate pulley 8 at the lower side of the intermediate portion, and the separation portion 10 extends along the lower side of the selection belt 4. Therefore, since the lower side of the sorting belt 4 can be taken out to the side of the side wall frame 9 or can be put inside, the sorting belt 4 can greatly loosen the belt tension by taking out the lower side from the space 10. Can be easily and quickly attached and detached.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings. First, based on FIG. 1 to FIG. 4, the brush roller 1 mounted on the frame 14 in a pair of left and right parallels looks at the supply chute 11 on the start end and sets the end to the sorting device 12. It is looking over the starting end of the sorting belt 4. The fruits K such as carrots and sweet potatoes supplied from the supply shooter 11 are supplied to the sorting belt 4 one by one at regular intervals while being transported along the valley 13 between the pair of left and right brush rollers 1. Each of the brush rollers 1 is formed by implanting a brush 3 on the outer peripheral surface of a cylindrical roll core 2 integrated with a roll shaft 5 to form a flat brush roll. It is planted in a state where the leading end is inclined to the brush inclination angles A and B at acute angles as appropriate toward the transport direction side of the roll shaft 5. By planting such brushes at the inclination angles A and B, the fruit K placed on the valley 13 is subjected to the brushing action by the rotation of the brush rollers 1, and the inclination angles A and B of the brush 3. Moved toward B side. The brush 3A at the start end in the transfer direction is set at a steep inclination angle A (for example, A ≒ 87 degrees), and the brush 3B at the end end is set at a gentle inclination angle B (for example, B ≒ 80 degrees). The brush 3B on the terminal end side is set to have a smaller inclination angle (A> B) than the brush 3B on the terminal end side than the brush 3A on the start end side.
[0011]
In such a brush roller 1, brushes 3 </ b> A and 3 </ b> B having different inclination angles A and B are planted on the peripheral surface of a single roll core 2. Brush rollers separately configured for each of the brushes 3 </ b> A and 3 </ b> B are appropriately arranged. It is also possible to adopt a form in which the length is set and connected. The brushes 3 are implanted in two stages with the inclination angles A and B over different lengths in the axial direction. However, the inclination angles are continuously set in the axial direction so as to be gradually inclined. You can also.
[0012]
The shooter 11 rotates the belt with lugs to convey the fruit K supplied from the hopper 15 and supplies the fruit K onto the start end of the brush roller 1. An auxiliary roller 16 and a guide plate 17 are provided on the starter of the brush roller 1 on the shooter 11 side, and the supplied fruit K passes over the rotary brush roller 1 to the rotation side or between the shooter and the shooter. We guide so that we are not pinched. Each of the roll shafts 5 and the roll shaft 18 of the auxiliary roller 16 are driven and rotated in a predetermined direction by a chain 21 hung between the roll shaft 18 and a shaft 20 of a motor 19. Reference numeral 22 denotes a guide rod, which can prevent the fruit K from falling when the space between the left and right brush rollers 1 is wide. The guide rod 22 is rotatably provided in the form of a round bar, so that the contact resistance with the fruit K can be reduced.
[0013]
The fruit A conveyed from the supply chute 11 is supplied onto the start end of the valley 13 between the brush rollers 1. The fruit A is subjected to a brushing action by being brought into sliding contact with the rotating peripheral surface of the brush roller 1. At this time, if the fruits K are superimposed on each other, a part of the fruits K will be pushed up in the rotation direction of the brush roller 1, but there are an auxiliary roller 16 and a guide plate 17 on this side, and the shooter 11 Is guided so as not to be scraped into the rotating part. When the brush 3A is rolled and conveyed in the direction of the roll axis 5 at the inclination angle A by the inclination angle A, the fruits K in the valleys 13 are spaced from each other, and are aligned in the front-back direction. Subsequently, when the fruit K comes to the position of the brush 3B from the brush 3A, the inclination angle B becomes loose, so that the conveying action in the direction of the roll axis 5 increases, and a certain interval is opened between the fruit K and the succeeding fruit K. . Since a series of these alignments and the formation of an interval based on the difference in the transport speed are performed on the same brush roller 3, smooth and rapid operations are performed.
[0014]
As the brush roller 1, the inclination angles A, B, and C of the brush 3 can be set in three stages as shown in FIG. For example, the inclination angle A of the brush 3A at the start end is about 85 degrees, the inclination angle B of the brush 3B at the middle is about 85 degrees, and the inclination angle C of the brush 3C at the end is about 80 degrees. . The fruit K supplied to the brush 3A portion is conveyed sequentially and rapidly as the brushes 3A, 3B, and 3C having the three-stage speed difference move in this order, and the front and rear fruit K intervals are also gradually widened.
[0015]
Further, as shown in FIG. 6, a brush 3D having no inclination angle may be provided at the starting end of the brush roller 1. The planting angle D of the brush 3D is set to a right angle state (D ≒ 90 degrees) like a normal brush roller. After the brush 3D, brushes 3A, 3B and the like having the inclination angles A (≒ 87 degrees) and B (≒ 80 degrees) as described above are arranged and formed. In the brush 3D portion, since the conveying force of the fruit K is small, the brushing action is improved, and the fruit K is gradually sent out in the conveying direction, so that an interval between the brushes 3A and 3B can be easily generated. .
[0016]
Next, points different from the above example will be described mainly based on FIGS. 7 to 10. A sorting belt 4 is arranged on the end side of the brush roller 1. The fruit K conveyed along the valley 13 between the left and right brush rollers 1 is weighed while being transferred by the sorting belt 4 while being transferred. It is sorted for each weighing section and discharged to the side. The sorting belt 4 is provided horizontally with the upper surface substantially at the same height as the valley portion 13 of the brush roller 1 so as to reduce the step of the inherited portion of the fruit K. The sorting belt 4 is a flat belt having a constant width, and is stretched between the left and right side wall frames 9 by front and rear pulleys 6 and 7 and an intermediate pulley 8 located at a lower intermediate portion therebetween. .
[0017]
The front and rear pulleys 6 and 7 are guided so that the pulley shafts 23 and 24 can be moved forward and backward with respect to the side wall frame 9 into the elongated holes so that the sorting belt 4 can be slackened. The intermediate pulley 8 is supported on the side wall frame 9 by a pulley shaft 24. Tension pulleys 26 and 27 are pressed by front and rear upper portions of the intermediate pulley 8 with tension rods 28 and 29 from the front and rear to maintain the winding pressure of the selection belt 4 on the intermediate pulley 8. Reference numerals 30 and 31 denote adjusting nuts for these tensioning rods 28 and 29, which can adjust the tensioning pressure of the tensioning pulleys 26 and 27. A slit-shaped space 10 is formed in the left and right side wall frames 9 along the lower side of the sorting belt 4 thus stretched. The lower side of the sorting belt 4 can be moved from side to side in and out of the spacing section 10. Due to the formation of the space portion 10, the side wall frame 9 on this side is configured to be vertically separated. Therefore, the sorting belt 4 stretched over the front and rear pulleys 6, 7 and the intermediate pulley 8 is removed from the outer peripheral portion of the upper side wall frame 9 which supports these pulleys 6, 7, 8 and the like. Can be.
[0018]
When removing the sorting belt 4 for replacement or the like, the tension pulleys 26 and 27 by the nuts 30 and 31 and the front and rear pulleys 6 and 7 are loosened to loosen the sorting belt 4. Here, the lower side portion of the selection belt 4 is moved outward from the horizontal interval portion 10. When the lower side is pulled out of the side wall frame 9 in this way, the sorting belt 4 is largely loosened, so that the front and rear ends can be easily removed from the front and rear pulleys 6 and 7. When a new sorting belt 4 is stretched, the procedure can be reversed. Since the side wall frame 9 is not removed when the selection belt 4 is attached / detached in this manner, the attachment / detachment operation can be simplified and facilitated.
[0019]
In the transporting process of the sorting belt 4, a weighing device 32 composed of a load cell for measuring the weight of the transported fruit K, and a discharging lever 33 of each sorting area that is operated to discharge upon receiving an output signal from the weighing device 32. And are arranged. The weighing device 32 is mounted on the mounting base 36 integral with the side wall frame 9 via a vibration-proof rubber 35 in a vibration-proof manner, and performs accurate measurement. Reference numeral 37 denotes a load cell on the weighing device 32, and reference numeral 38 denotes a belt slider on the front and rear sides of the machine, which slides and supports the bottom surface of the rotating selection belt 4. The ejection lever 33 and the electromagnetic solenoid 40 are attached to a bracket 45 attached to the side wall frame 9. The discharge lever 33 is rotatably supported around the lever shaft 34 with respect to the window 39 of the side wall frame 9, and is rotated E along the upper surface of the selection belt 4. A solenoid rod 41 of an electromagnetic solenoid 40 is connected to a base portion 43 of the discharge lever 33 via a link 42, and the solenoid 40 is energized by a signal from the measuring device 32 to turn the discharge lever 33 to rotate E. The transported fruit K on the sorting belt 4 is discharged to each sorting shooter 44 on the outside. Reference numeral 46 denotes a motor that rotates the selection belt 4 by interlocking the pulley shaft 25 via a chain 47.
