Description

  The present invention relates to a cherries particle size sorting device that sorts the size of cherries by placing and transporting cherries on the upper surface of a belt arranged so that the interval between two adjacent belts gradually increases. Relates to a cherries particle size sorting apparatus provided with posture control means for aligning the cherries on the belt with the correct posture.

  Conventionally, two adjacent belts are stretched so that the interval is gradually widened, and fruits or root vegetables are placed and conveyed on these belts. There exists an apparatus that sorts etc. by particle size (for example, see Patent Documents 1 and 2).

  Further, in the particle size sorting apparatus, a posture control plate having elasticity such as a rubber plate is attached by retreating from the outside toward the belt running direction so as to sandwich both belts, and long root vegetables such as carrots are aligned. An apparatus has been proposed (Patent Document 3).

  The above-mentioned particle size sorting apparatus for fruits and the like can properly sort the particle size for roughly spherical items such as apples and pears, but, like cherries, from fruits and shafts (stems) As a result, the shaft portion is caught by the belt, and the particle size cannot be well selected.

  As shown in Patent Document 3, the particle size sorting apparatus provided with a posture control plate is a posture control plate that protrudes obliquely on the belt from the outside in the lateral direction of the belt for hard root vegetables such as carrots. It is possible to rotate the root vegetables along the slanting direction along the belt by contacting the root vegetables and follow the longitudinal direction, but the actual part is relatively soft and expensive like a cherries On the other hand, the posture control plate such as a rubber plate is in contact with the actual part, and the actual value is damaged, and the commercial value of the cherries is greatly reduced.

  Moreover, since the said attitude | position control board needs to be attached diagonally from the outer side of a belt, it can be applied only to the particle size sorter | straining apparatus of a line form which consists of two belts.

  Accordingly, an object of the present invention is to provide a cherries particle size sorting apparatus that can be applied to cherries and reliably sort the grain sizes without damaging the fruit.

In the present invention, a plurality of belts (10...) Are arranged so that the distance between the traveling upper side (10A) and (B) of two adjacent belts gradually increases from the traveling upstream side toward the downstream side. In the cherries particle size selection apparatus, the cherries are dropped from the interval according to the particle size by placing and transporting the cherries (S) on the belt,
A posture changing member (41) made of a flexible material having elasticity capable of changing the posture of the cherries by touching the cherries without damaging the cherries is attached to the upper surface (10a) of the belt on the upper side of the running. Arrange so that the tip is located,
The posture changing member (41) contacts the shaft (Sk) of the cherries (S) on the belt (10) in the running state, so that the shaft is parallel to the running direction (A) of the belt (10). It is characterized by changing the posture of the cherries in the following direction.

  The posture changing member is a brush body (41) made up of a plurality of raised hairs (41a) having a predetermined length, and the tip of the raised hair faces the upper surface of the belt from above the running upper belt. It is arranged in the direction to do. In addition, the arrangement | positioning from the upper direction of the said brush body is not limited from right above, but is the concept also including diagonally upward. Moreover, the thing in which the front-end | tip of a brush body is contacting the belt and the thing slightly separated are included.

  The belt (10) includes at least three belts, and a plurality of transfer rows for transferring the cherries according to the belt interval (B).

  The belt is a round belt (10) having a circular cross section.

  Rolling prevention guides (20, 20) for preventing rolling of the belt are provided in contact with the outer surface of the upper side of the belt running on the laterally outer side of the belt.

  In addition, although the code | symbol in the said parenthesis is for contrast with drawing, it has no influence on a claim by this.

  The particle size sorting apparatus according to the present invention is provided with a posture changing member made of a flexible material having elasticity that can change the posture of the cherries by contacting the cherries without damaging the cherries. Therefore, the cherries can be applied to the cherries and the cherries can be reliably and accurately selected without damaging the cherries.

  Since the posture changing member is composed of a brush body made up of a number of nappings of a predetermined length, even if the napping comes into contact with the cherries, the nappings do not hurt the fruits by flexibly deforming, and nappings By abutting on the shaft, the posture of the cherries can be easily changed in a direction parallel to the belt running direction, thereby providing a highly reliable cherries particle size sorting apparatus.

  In addition, since the brush body is arranged in the direction in which the tip of the raised hair is opposed to the upper surface of the belt from above the belt, the posture changing member made of the brush body can be arranged for each of three or more belts, Cherries can be transported and sorted by multiple rows.

  Using three or more belts, the cherries can be transferred at intervals of a plurality of belts, and the cherries can be sorted efficiently with a particle size.

  By using a round belt with a circular cross section, even if the posture changing member is made of a flexible member that does not damage the cherries, the posture of the cherries can be easily and reliably changed as the belt runs.

  Rolling prevention guide that comes in contact with the belt can prevent the rolling of the belt, especially when using three or more belts, preventing the rolling of the outer belt, and the accuracy of selecting the grain size of the cherries Can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the cherry particle size sorting apparatus 1 has a frame 2 composed of a plurality of horizontal frames 2a, vertical frames 2b, etc., and wheels are provided at the lower four corners of the frame. 3 are attached. Pulley shafts 5 and 6 are rotatably supported at both ends in the longitudinal direction of the frame body 2. Three pulleys 7 and 9 are attached to each pulley shaft 5 and 6 by a key or the like, respectively, and a round belt 10 (see FIG. 3) having a circular cross section is provided on each pulley. It is wound in the direction.

  The traveling upper side 10A of the three belts 10 serves as a cherry mounting surface and travels in the direction of the arrow A, but the three pulleys 7 are substantially closely (or close) to the pulley shaft 5 on the upstream side of traveling. Are arranged on the pulley shaft 6 on the downstream side of the travel, between the pulleys 9... Therefore, the belts 10 wound around the pulleys 7 and 9 on the upstream side and the downstream side are set so that the interval B between the adjacent belts is narrow on the upstream side and gradually widens toward the downstream side. The two spacer rings 11, 11 are fixed to the pulley shaft 6 and rotate together with the pulley 9, and a urethane sponge 12 is fitted on the outer periphery thereof so as not to damage the cherries.

  A sprocket 13 is fixed to the pulley shaft 6 on the downstream side, and a motor 15 is attached to the frame 2 below the pulley shaft. An output shaft (drive) sprocket 15 a of the motor, the sprocket 13, Are linked by a chain 16. The drive portion from the pulley shaft 6 and the motor 15 is covered with a cover 17, and the upstream pulley portion is also covered with a cover 19. Further, the outer belts of the three belts 10 are in contact with the outer side surface of the upper side of the traveling upper side 10A with the bow-shaped belt roll prevention guides 20 and 20, which are frame bodies. 2 is attached by a rod or the like.

  A cherry supply stand 21 is attached above the upstream pulley 7. The supply base has a substantially trapezoidal shape, and has a structure in which an edge 21a is raised around the periphery, and the cherries can be supplied toward the supply part C on the upstream side of the belt 10. The supply base 21 is connected by hooking an engagement groove to a pin 22 provided on the frame body 2 and supported by a foldable support leg 23, and a knob bolt 26 is provided in an adjustment groove 25 having a plurality of notches. By selecting and engaging, the tilt angle can be adjusted.

  A large-diameter cherry discharge shooter 27 is attached to the downstream frame 2 so as to protrude in the downstream direction, and a mounting table 29 such as a box is attached to the lower side thereof. Further, there is a particle size sorting table 30 which is positioned below the upper traveling side 10A of the belt 10 serving as a cherry transport surface and above the lower belt traveling surface 10B and divided into a plurality of parts in the transporting (traveling) direction A. As shown in detail in FIG. 3, the sorting table is provided across the front and rear of the frame body 2 with an inclination in a direction orthogonal to the transfer direction (that is, toward the front direction), Each partition wall 31 is raised with its upper portion inclined (both directions and one direction) to form a cherry guide wall 31a.

  As shown in detail in FIGS. 3 and 4, the particle size selection table 30 is supported on the frame body 2 via a hinge 32 on the upper side of the inclination, and is a long hole provided on the frame body 2 on the lower side of the inclination. The shaft portion 35 is adjusted and fixed to 33a, and the inclination angle is adjusted. Reference numeral 36 in the figure denotes a bearing support plate that supports the pulley shaft 5, and the tension of the belt 10 can be adjusted by a bolt 37.

  As shown in detail in FIGS. 3, 4, and 5, a posture control member mounting plate 39 is mounted via a bracket 38 over the upper and lower horizontal frames 2 a before and after the frame 2. The mounting plate 39 is positioned above the traveling upper belt 10A slightly downstream of the supply portion C that supplies the cherry from the cherry supply base 21 to the belt placement surface 10a. The base of the brush body 41 is fixed by 42. The brush body 41 has a large number of raised hairs 41a having a predetermined length implanted in the base portion, and the tip of the raised hair 41a is the upper surface (cherry placement surface) of the belt 10A on the running upper side from above. 10a, the brush body 41 does not damage the cherries Sf even if they abut against the cherries S, and abuts the cherries shaft (stem) Sk to change the cherries posture. The cherries posture changing member is made of a flexible material having a flexible elasticity. These brush bodies 41 are provided so that at least one brush body 41 corresponds to each belt 10..., As shown in FIG. ing.

  Next, the operation of the cherry particle size sorting apparatus 1 will be described. When the power is turned on, the motor 15 rotates, and the rotation is transmitted to the pulley shaft 6 via the drive sprocket 15a, the chain 16, and the sprocket 13. Then, by the rotation of the pulley shaft 6, the three pulleys 9, the belt 10 and the pulley 7 which are transfer devices (conveyance conveyors) are driven, and the three belts 10 ... are substantially horizontal on the traveling upstream side 10A. The vehicle travels at the same speed in the direction of arrow A.

  A lot of harvested cherries S are placed on the cherry supply table 21, and the cherries on the supply table 21 are supplied from the supply port to the transfer device supply unit C including three belts 10 by a predetermined amount based on the inclination. The In the supply section C, which is on the upstream side of the travel, these belts have a narrow interval B between the belts, and the cherries S are placed between the belts made of the round belt 10 without falling from the interval. Transfer is started toward the downstream side. In the supply part C, as shown in FIG. 5, the cherries S have the axis (stem) Sk oriented in an arbitrary direction.

Then, as the belts 10 travel in the direction of arrow A, the cherries S come into contact with the brush bodies 41 disposed opposite to each other. When the brush body 41 comes into contact with the actual part Sf of the cherry S, the brush body is composed of flexible raised hairs 41a having a predetermined length depending on the upper side. . For example, in FIG. 5, the cherries S ₁ in which the shaft S is directed to the outside of the belt 10 (outside of the drawing) and the actual Sf is placed on the belt interval are part of the actual Sf in the brush body 41 as the belt is transferred. It abuts against an intermediate portion of the raised hair 41a having a predetermined length. Then, the many raised hairs 41a of the brush body are deformed so as to follow the actual outer diameter, and contact with a large contact area reduces the contact pressure with respect to the actual hair. It bends (upward in the figure) and easily deforms without damaging the fruit.

When the brush body 41 comes into contact with the shaft (stem) portion Sk of the cherry S, the raised hair 41a whose tip is in contact with the round belt 10 (near the top of the round belt 10) contacts the shaft Sk and moves with the belt. Resist. For example, the cherries S ₁ shown in FIG. 5 are in contact with substantially the entire surface of the raised hairs 41a from the lateral direction of the axis Sk, and the brush body 41 is at a predetermined pressure against the deformation of the entire raised hairs in the belt transfer direction A. Resists and relatively retracts the shaft Sk with the actual transfer by the belt. At this time, since the belt 10 is formed of a round belt having a circular cross section, the actual Sf is placed on the belt interval, and the belt gradually spreads on the downstream side after traveling, so that the actual portion Sf is reduced by the running resistance of the shaft portion Sk. easily rotated, cherry, as shown in S ₂ in FIG. 5, is the posture change in the direction in which the axis Sk is parallel to the running direction a of the belt retracted, as further shown in S _3, the shaft Sk Are aligned so as to be positioned at the belt interval B.

  The two rows of cherries S... Aligned in this way are transferred to the downstream side by the transfer device comprising the belt upper side 10A, and the belt interval B of the two rows gradually increases with the transfer. . When the belt interval becomes equal to or larger than the grain size Sf of the cherries S, the cherries fall on the sorting table 30 from the interval B, and each cherries that have fallen on the sorting table divided into a plurality of pieces slide down due to the inclination. Each box is sorted and stored by particle size. The cherries having a large particle size remaining to the end on the belt interval are discharged to the shooter 27 without being damaged by the urethane sponge 12 of the downstream ring 9 and the spacer ring 11 between the pulleys. Sorted and stored in a box.

  At this time, the cherries S are aligned so that the shaft Sk is positioned on the rear side of the actual Sf, so that selection failure due to the shaft being caught on the belt can be prevented, and large cherries from the wake end can be prevented. When releasing the cherries, the shaft is not broken. Further, in the traveling upper side 10A serving as the transfer surface, the middle part of the outer two belts 10, 10 is prevented from rolling by the rolling prevention guides 20, 20, and the particle size is selected while maintaining high accuracy. Is done.

  In the above-described embodiment, three belts 10 are used to transfer and sort the cherries in two rows. However, the invention is not limited to this, and the belts are transferred and sorted at intervals of one row by two belts at the minimum. Alternatively, the sorting ability may be enhanced by using more belts such as three rows of four belts.

  In addition, the brush body 41 hangs down from the top toward the belt. However, this may be disposed obliquely downward by a predetermined angle in the left-right direction and the front-rear direction, and the tip of the brush body 41 contacts the belt. Even if they are not in contact with each other, they may be slightly separated from each other, and it is difficult to transfer a large number of rows, but they may be arranged laterally from the outside of the belt. Further, as described above, the brush body is preferable as the posture changing member, but it is not limited thereto, and other materials having the same flexibility such as sponge felt may be used. Furthermore, the belt serving as the cherries transferring device is preferably a round belt, but is not limited to this, and may have other cross-sectional shapes such as a V belt and a flat belt.
