  As described above, the bean sprouts that are currently distributed as commodities have been separated and removed from the shells, follicles and short bean sprouts, but sprouted but ungrown bean sprouts and broken bean sprouts with a certain length. Often, there are many bean sprout products that you don't want to make. In particular, ungrown bean sprouts are rounded or thickened and have a certain size, and the bent parts are entangled with other bean sprouts. It is difficult to separate and remove together with shells, follicles and short bean sprouts, and often they are not separated by conventional methods.

  As described above, ungrown bean sprouts are difficult to separate and remove by conventional methods, but if they are mixed, the appearance of commercial bean sprouts will be damaged, and ungrown bean sprouts Often fragile. It is hoped that the appearance of the commercial bean sprout will be further improved, and it will be more than conventional refining for bean sprout, such as packaging in the lengthwise direction and removing the buds and roots from both ends of the bean sprout. It is easy to be a hindrance that these ungrown bean sprouts are mixed.

  It is an object of the present invention to provide a bean sprout sorting apparatus that can separate and remove bean sprouts that are harvested from ungrown bean sprouts and that have a certain length but are broken. It is said.

To solve the above problems, the present invention has a square moving conveyor to form a square of a predetermined interval, and a belt conveyor which runs keeping the squared conveyor and a small distance below the squares conveyor, the A plurality of vertical bars arranged extending in the travel direction of the grid conveyor while maintaining a space between adjacent ones, and a vertical bar attached to an endless chain and orthogonal to the vertical bar A bar conveyor having a horizontal bar that is moved in the length direction of the horizontal bar, and is attached to the lower surface of the horizontal bar at predetermined intervals, and a hanging piece is provided between the vertical bars. the sprouts to be treated on the conveyor by transferring supplied in a dispersed state, leaving a predetermined length or more sprouts on the square conveyor, or the predetermined length than dropped from the square The sprout by contact with the suspended piece conveyed As the travel of the bar conveyor without falling onto the belt conveyor, and separated non-growing bean sprouts and predetermined length following sprouts on said belt conveyor A bean sprout sorting device is provided.

Further, in the sorting apparatus of the bean sprouts according to the invention, the squares of the squares of the conveyor in cross section circular or circular shape, and the longitudinal bars and the transverse bar at least the upper half having a circular or circular cross-section It is desirable to form with.
Moreover, it is preferable that the running speed of the belt conveyor is slower than the running speed of the bar conveyor.
Further, the feeding belt conveyor for discharging the selected sprouts longer than the predetermined length after being separated and removed by the mesh conveyor, and the belt conveyor and the feeding belt conveyor are separated and removed. It is preferable to have a gap for dropping and discharging a thing of a predetermined length or less.
At this time, it is preferable that the said clearance gap is located in the running direction upstream of the said grid conveyor rather than the said delivery conveyor.
Moreover, it is preferable to have a blower that blows air toward the sprouts to be processed on the square conveyor.

  As described above, the bean sprouts sorting apparatus according to the present invention is composed of a mesh conveyor that moves by forming a mesh with a predetermined interval, and a belt conveyor that travels at a small interval below the same mesh conveyor. And the structure is simple. According to the bean sprout sorting apparatus of the present invention, the ungrown bean sprout and the bean sprout having a predetermined length or less are dropped and separated on the lower belt conveyer by the sieving action of the reed in the reed conveyor. In the bean sprout sorting apparatus of the present invention, a belt conveyor that travels at a small distance from the grid conveyor is arranged below the grid conveyor, so that it has a length greater than a predetermined length and is separated. Even if the bean sprouts that do not need to be in the vertical or oblique state are going to fall after passing through the meshes of the mesh conveyor, the bean sprouts run at a small distance from the mesh conveyor below the mesh conveyor It is supported by a belt conveyor that does not fall off and separate from the grid conveyor. Thus, according to the bean sprout sorting apparatus of the present invention, only ungrown bean sprouts and bean sprouts having a predetermined length or less can be efficiently separated and removed.

  In the bean sprouts sorting apparatus according to the present invention, the grid conveyor is provided with a plurality of vertical bars arranged extending in the running direction of the conveyor with a space between adjacent ones, and the vertical bar attached to an endless chain. In the case of a bar conveyor having a horizontal bar that is moved in the longitudinal direction of the vertical bar, the position of the vertical bar that intersects the horizontal bar and forms each cell is sometimes changed by the movement of the bar conveyor. Since it changes every moment, the sprouts supplied on the grid conveyor remain in the same horizontal bar and vertical bar position, and ungrown short bean sprouts and broken short bean sprouts remain on the grid conveyor and remain unseparated It is prevented.

  In the bean sprout sorting apparatus according to the present invention, when the mesh of the mesh conveyor is formed of a bar having a circular or circular cross section and at least an upper half of the mesh, it is placed on the bar forming the mesh. Tends to change posture without staying on a bar whose upper surface is circular or circular, and the short bean sprouts fall off from the squares because they are ungrown or broken. It is possible to separate and extract only a predetermined length of sprouts by performing regular separation.

Hereinafter, a sorting apparatus according to an embodiment of the present invention will be described with reference to the drawings. In the figure, a bean sprout sorting apparatus 1 has a vertical bar 2 attached between support bars 3 and 4 with an equal interval between adjacent ones. Further, an endless bar conveyor 6 having a large number of horizontal bars 5 orthogonal to the length direction of the vertical bar 2 and running along the length direction of the vertical bar 2 is provided. The bar conveyor 6 has two endless chains 11 that are stretched over chain wheels 9 and 10 that are disposed at both ends of shafts 7 and 8 that are disposed at intervals, and these two endless chains. The horizontal bar 5 is attached at both ends with a space between the adjacent ones. The vertical bar 2 and the horizontal bar 5 have a circular or circular cross section, a circular shape such as a circle or an ellipse at least in the upper half, and a shape in which the bean sprout is not caught.
A hanging piece 5 ′ is attached to the lower surface of the horizontal bar 5 at a predetermined interval. The hanging piece 5 ′ is fitted between the vertical bars 2, and the lower end of the hanging piece 5 ′ is between the belt conveyor 15 described later. It is configured to move while keeping.

  The bar conveyor 6 is configured such that the upper travel path travels from the right to the left in FIG. 1 by the shaft 8 driven and rotated by the motor 12, and when the bar conveyor 6 travels, the horizontal bar 5 Is configured to be transported while forming a grid crossing the vertical bar 2 in the upper travel path. Thus, the bar conveyor 6 provided with the vertical bar 2 and the horizontal bar 5 constitutes a square conveyor which is moved by forming a square in the sprouts sorting apparatus of the present invention.

Below the grid conveyor, a belt conveyor 15 is disposed at a small distance from the grid conveyor. In other words, the belt conveyor 15 is composed of rollers 13 and 14 arranged at a distance from each other and an endless belt stretched around the rollers 13 and 14. The rollers 14 are driven and rotated by a motor 16. The belt conveyor 15 is configured to travel from the right to the left in FIG. The traveling speed of the belt conveyor 15 is slower than the traveling speed of the bar conveyor 6, and due to the difference in speed between the two, ungrown bean sprouts and sprouts having a predetermined length or less surely fall from the square conveyor onto the lower belt conveyor 15. Configured to be separated.

  The small interval maintained between the mesh conveyor and the belt conveyor 15 is a predetermined length that causes ungrown bean sprouts to be separated and removed, and broken short bean sprouts to be dropped from the grid conveyor to the belt conveyor 15, but need not be separated and removed. The larger bean sprouts are selected so as to be transported as the bar conveyor 6 travels without falling onto the belt conveyor 15 after coming into contact with the hanging piece 5 'provided on the horizontal bar 5. . The size of the mesh is appropriately selected depending on the size of the sprouts to be separated, but can be about 3 to 4 cm as an example.

Reference numeral 17 denotes a feed belt conveyor for discharging the selected sprouts after separating the ungrown bean sprouts by the grid conveyor. The endless belt 20 is wound around the rolls 18 and 19 attached to the shaft 8. Has been.
A gap 22 is formed between the belt conveyor 15 and the endless belt 20, and ungrown bean sprouts separated on the belt conveyor are dropped downward from the gap. Note that the sprouts to be sorted are supplied so as to be placed in a dispersed state on the right end of the drawing by a suitable hopper (not shown) on the grid conveyor.
Reference numeral 21 denotes an air outlet of the blower. By blowing air onto the mesh conveyor, the ungrown bean sprout and the short bean sprout that are caught or entangled with the vertical bar 2 and the horizontal bar 5 constituting the grid conveyor. It works to drop from the grid conveyor to the lower belt conveyor 15.

The apparatus according to the present embodiment has the above-described configuration, and bean sprouts are sorted by this apparatus as follows. The harvested sprouts that should be separated and separated from ungrown bean sprouts are distributed from the hopper, etc., and supplied on the right-hand side of the square conveyor, on the square conveyor where the vertical bar 2 and horizontal bar 5 are formed. To be placed in a dispersed state. Due to the air blown from the air outlet 21 of the blower against the mesh conveyor, ungrown bean sprouts and broken short bean sprouts of a size that can pass through the mesh are dropped onto the belt conveyor 15 running below. To be separated. Even if a sprout having a length that does not require separation may enter the mesh, the belt conveyor 15 can be received at a small distance below the mesh conveyor, and the hanging piece 5 provided on the horizontal bar 5 can be received. Since ′ is present, the whole is not lowered and is conveyed together with the mesh conveyor. Thus non-growing sprouts and a predetermined length following sprouts sprouts which are separated screened is discharged from the belt conveyor 17 feeding of the left end. Ungrown bean sprouts separated on the belt conveyor 15 are dropped and discharged from the gap 22 between the belt conveyor 15 and the endless belt 20.

Although the apparatus according to the illustrated embodiment of the present invention has been described above, it is needless to say that the present invention is not limited to this embodiment.
For example, in the illustrated embodiment, the grid conveyor is composed of the vertical bars 2 and the bar conveyor 6 that are stationary, but may be configured by being assembled in a grid shape in advance. In the illustrated embodiment, the size of the grid of the grid conveyor formed by the vertical bar 2 and the horizontal bar 5 is fixed, but the bean sprouts are shaped and length depending on the raw beans and growth conditions. The size of the sprouts to be separated and the length of the sprouts to be separated can be selected because of different thicknesses, etc. May be. It is also preferable that the distance between the grid conveyor and the belt conveyor 15 below the grid conveyor can be adjusted.

Further, in the apparatus according to the illustrated embodiment, the vertical bar 2 forming the grid conveyor is described as being stationary and the horizontal bar 5 is merely traveling, but at least one of them may be vibrated by a vibrator. Further, by rotating around the axis in the length direction, it is possible to perform an action of helping the ungrown bean sprouts to be separated, which are caught on the mesh conveyor, to fall from the mesh.
Further, the sprouts to be separated are prevented from being placed on the grid conveyor by blowing out air from the blower, but instead of this, it may be configured to be scraped off by a brush.
