Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fruits and vegetables feeding roller that feeds and feeds a large amount of fruits and vegetables supplied in a row at an appropriate interval, in order to accurately place a large amount of fruits and vegetables on a sorting tray or the like of a fruits and vegetables sorting apparatus.

  Techniques such as a brush roller that inclines the planting angle of the brush with respect to the roll axis on the peripheral surface of the roll core in the brush roll, and a spiral brush roller in which the brush rotation surface of the brush roller is formed in a spiral form are known.

  For fruit and vegetable processing equipment such as bell peppers, potatoes, mandarin oranges, apples and other fruit and vegetable sorting equipment, etc. It is necessary to install the components. In the form of conveying in the axial direction of the brush roll by the brush roll in the spiral form, the fruits and vegetables being conveyed often jump over or over the rotating peripheral surface of the spiral brush, and it is difficult to accurately feed and convey the fruits and vegetables one by one. It is difficult to stabilize.

In the first aspect of the present invention, columnar brush rolls 1 in which brushes are planted on the outer peripheral surface of the roll core 11 are arranged in parallel in a pair of left and right, and the fruits and vegetables W are placed in the valleys 12 between the left and right brush rolls 1. In the feeding roller that feeds and conveys the valley portion 12 along the conveying direction while polishing the fruits and vegetables W, the tip ends of the brushes of the pair of left and right brush rolls 1 are protruded outward. The lower-side brush 1B is inclined toward the conveying direction side with respect to the upper-side brush 1E or 1A in the feeding and conveying direction, or a gentler inclination is set with respect to the outer peripheral surface of the brush roll core 11 At an end of the brush roll 1 on either one of the left and right sides, the length of the brush is shortened so that the rotational diameter D2 is smaller than the rotational diameter D1 of the upper side of the brush roll 1. A small rotating diameter portion 4 is formed, and a step edge 3 of the boundary portion is formed with a feeding edge 2 projecting obliquely toward the rear side in the rotation direction of the brush roll 1 and toward the conveyance direction side. The fruit and vegetables feeding roller is characterized in that the fruit and vegetables W received by the small rotation diameter part 4 formed by the brush 1E or 1B located on the lower side is fed forward by the delivery edge 2 one by one while polishing the fruit and vegetables W. To do.

By rotation of the brush roll 1, the fruits and vegetables supplied to the starting end portion between the brush rolls 1 are conveyed while being rotated along the roll axis direction while being brushed and polished by the rotation of the brush . At this time, with respect to the brush 1A or 1E on the upper side of the brush roll 1 along the valley portion 12 for conveying the fruits and vegetables W , the lower brush 1B sequentially forms the planting inclination angle in the feeding and conveying direction in a gentle inclination. Therefore , the conveyance speed increases as the valley portion 12 is conveyed along the conveyance direction, and the fruits and vegetables W are arranged in a line by this conveyance, and the interval between the front and rear fruits and vegetables W is set. A part becomes easy to be formed. The fruits and vegetables W arranged in a row fall from the step edge 3 of the brush roll 1 to the small rotation diameter portion 4 on the terminal side, and are acted on the delivery edge 2 of the circumferential surface of the small rotation diameter portion 4 to quickly move forward. The space between the subsequent fruits and vegetables is greatly separated.
Thus, when the fruits and vegetables conveyed by the brush roll 1 along the conveyance direction along the valley portion 12 are in a line state, and each fruit and vegetable W is formed with a front-rear interval portion, from the rotation diameter D1 of the brush roll 1 The step edge 3 having a small diameter is dropped to the rotation diameter D2. The falling speed of the fruits falling on the step edge 3 is further increased, and the front-rear distance from the succeeding fruits and vegetables is greatly increased. Moreover, the small rotation diameter portion 4 having a small rotation diameter D2 is also sent by rotation of the delivery edge 2 that projects obliquely forward from the step edge 3 while being polished by the brush. However, while keeping the conveyance interval large, each fruit and vegetable is separated and delivered accurately one by one.

The invention according to claim 1, a pair of left and right horizontal, and the forming valleys 12 of the parallel form between the brush roll 1 by rotating by placing the fresh produce W, fruits and vegetables W is the upstream side of the valley portion 12 The brush 1E having a steep inclination angle located at 1A and 1A and the brush 1B having a gentle inclination angle located on the lower side of the brush 1B are acted on to increase the conveying speed and gradually increase from the overlapping contact state between them. Arranged in a line, a space is formed for each fruit and vegetable W. For this reason, the fruits and vegetables W fed and conveyed along the conveying direction in the valley portion 12 between the cylindrical brush rolls 1 are subjected to frictional rotation by the rotation of the brush rolls 1 and are spiraled when conveyed. Since the ridge-like uneven surface is not formed, there is less swinging phenomenon that part of the transported fruits and vegetables floats upward or jumps up from the valley portion 12, so It is possible to remove the weight and polish it while maintaining a quiet and smooth rotation, and it is possible to perform stable feeding and feeding.

Further, a step edge 3 is formed at the front end portion of the brush roll 1 forming the valley portion 12, and each time the fruits and vegetables W are dropped at the step edge 3 portion, the falling speed is increased to follow the step edge 3. The gap between the fruits and vegetables can be widened. Then, while the fruits and vegetables W fed to the small rotation diameter portion 4 are polished with the brush of the small rotation diameter portion 4, the fruits and vegetables W are rapidly sent out to the front side by the action of the sending edge 2 at the front end portion, The feeding interval is greatly separated or maintained, and the paper is fed out intermittently and accurately at a constant timing.

Based on FIGS. 1-3, it comprises as a feeding supply apparatus which pays out and mounts to each sorting tray 7 of the weight sizer 6 which measures and sorts fruits and vegetables W, such as a bell pepper. The brush roll 1 receives and feeds the fruits and vegetables W supplied from the supply hopper 8 and is mounted by a roll shaft 9 in a pair of left and right parallel states. By rotated by the fruit or vegetable W in the valley portion 12 between the pair of brush rolls 1, the valley portion 12 are conveyed along the direction of the roll axis 9 while polishing and rubbing the fruit or vegetable W. A supply hopper 8 is provided at the top of the start end of the brush roll 1, and a weight sizer 6 that is attached to the chain 10 and rotated and transported horizontally is provided at the bottom of the end of the transport direction. While the fruits and vegetables W fed and transported by the roll 1 are received and transported to the receiving tray 7 of the weight sizer 6, the weight of each fruits and vegetables W is measured by a load cell or the like and sorted into a plurality of weight division areas. .

This brush roll 1 has a cylindrical roll core 11 around a roll shaft 10, and brushes 1 </ b> A and 1 </ b> B having different planting inclination angles on the outer peripheral surface over the upper half and the lower half along the axial direction. To plant. That is, the brush having a predetermined length formed on the outer peripheral surface of the brush roll 1 is directed in the direction of the right angle E with respect to the length direction of the roll shaft 10 with the direction of the brush body directed radially to the roll core 11. it is common to implanted Te, but other brush 1E to be planted in the perpendicular direction E, of the roll shaft 10 to the tip portion of the brush with respect to the longitudinal direction of the roll shaft 10, to roll core 11 The form of the brushes 1A and 1B planted at an appropriate inclination angle toward the conveyance direction end portion side is also used. For example, the planting inclination angle A of the brush 1A on the upper side in the conveying direction of the brush roll 1 is set to about 85 degrees, the planting inclination angle B of the lower brush 1B is set to about 80 degrees, and the brush planting along the conveying direction is performed. The installation inclination angle is set to be loose (E>A> B) . Such setting of the inclination angle of the brush can be carried out by changing the angle to different angles over two or more stages. On the terminal end side of the brush roll 1, the brush 1B is shortened to form a step edge 3 and a small rotation diameter portion 4 having a small rotation diameter. From a part of the step edge 3 , a brush having a large rotation diameter D1 that can be implanted at the terminal end of the brush roll 1 is used in an oblique direction extending forward and rearward in the rotational direction, that is, appropriately in the rotational direction. The delivery edge 2 is formed so as to intersect at an angle C, and the fruits and vegetables W are engaged with the delivery edge 2 formed by this brush and pushed out to the end side. When the rotation diameter of the brush roll 1 on the upper side of the step edge 3 is D1, and the rotation diameter of the small rotation diameter portion 4 on the lower side is D2, these relationships are set as D2 <D1. The delivery edge 2 is formed at a part of the step edge 3 in the illustrated example, but it can also be formed at two or three places.

  Such a pair of left and right brush rolls 1 are rotated in the same direction around a horizontal roll shaft 9 to receive the fruits and vegetables W supplied from the supply hopper 8 on the valleys 12 between the brush rolls 1. The brush 1A moves toward the brush 1B. The fruits and vegetables W received by the valley 12 by the rotation of the brush roll 1 are moved in the tilt direction of the brushes 1A and 1B while being frictionally rotated. In addition, since the planting inclination angle becomes loose as it acts on the brush 1B from the brush 1A, the conveying speed is increased. For this reason, the space | interval part between the front and back of the fruits and vegetables W becomes large, and the fruits and vegetables W which were mutually superposed | polymerized in the valley part 12 in the supply hopper 8 parts are also gradually aligned and conveyed. In addition, the fruits and vegetables W drawn out on the lower brush 1B are intermittently drawn forward by the rotating delivery edge 2, and the space between the following fruits and vegetables W is greatly opened. The fruits and vegetables W fed out by the delivery edge 2 are rotated in this small rotation by rolling down from the delivery edge 2 or the step edge 3 to the small rotation diameter portion 4 due to a paragraph difference due to the rotation diameters D1 and D2 of the brush roll 1. The diameter portion 4 is quickly sent out over the end. The valley portion 12 of the brush roll 1 is transported to the end portion, and is placed for each sorting tray 7 of the weight sizer 6. For this reason, since the feeding interval of the fruits and vegetables W fed out from the end of the brush roll 1 is large, it is possible to divide each piece individually into the continuously rotating sorting tray 7 and accurately supply the drops at a fixed timing. can do.

In FIG. 3, the same brushes 1A and 1B are implanted in the pair of left and right brush rolls 1, but the brushes 1A and 1B having different implantation inclination angles A and B are the same as shown in FIGS. It can be formed on the brush roll 1 on the side, or can be formed on the brush rolls 1 on different sides as shown in FIG. 6 (FIG. 3) and FIG. In FIG. 4, the brush 1 </ b> E of the brush roll 1 on the other side is planted uniformly over the entire length in a direction substantially perpendicular to the normal roll shaft 11. Further, the step edge 3, the delivery edge 2, the small rotation diameter portion 4 and the like are formed on the brush 1B portion located on the lower side, but instead, formed on the brush 1E portion side located on the lower side. (See FIG. 7). Further, FIG. 5 shows a case where the step edge 3, the delivery edge 2, the small rotation diameter portion 4 and the like are formed on the left and right brush rolls 1. Further, in FIG. 7, the brush 1E is planted on the upper side of the brush roll 1 on one side and the brush 1B is planted on the lower side, and the brush 1A is planted on the upper side of the other brush roll 1 and the brush 1E is planted on the lower side. The brush 1E and the brush 1A are opposed to each other, and the brush 1B and the brush 1E are opposed to each other so that the brush 1B and the brush 1E are opposed to each other on both left and right sides of the valley portion 12 where the fruits and vegetables W are fed. Further, in FIG. 7, the step edge 3, the delivery edge 2, the small rotation diameter portion 4, and the like are formed on the brush roll 1 terminal portion , that is , the brush 1 E portion side located on the lower side .

  In the weight sizer 6, a support link 15 in the form of a parallel link is attached to a link plate 14 of a chain 10 stretched between a pair of sprockets 13, and the lower surface of the sorting plate 7 is attached to the support link 15 in the direction of rotation of the chain. It is provided around the fall shaft 16 so as to be able to turn over. In addition, the lower surface of the sorting plate 7 that is spaced apart from the overturning shaft 16 is supported by the stopper 17 portion of the support link 15 so that the support and accommodation posture of the fruits and vegetables W can be maintained. Further, a slider 18 is provided at one end of the support link 16 and is guided by a switching rail 19 attached to the sorting frame 20. The switching rail 19 is provided with a switching rail portion, which is interlocked by weighing with the load cell.
