Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic sorting machine that is capable of sorting long root vegetables, such as carrots, according to the shape and size of their varieties.

In general, there are many varieties of carrots, each with its own unique shape and size, so the standards for each class are different. Therefore, producers currently spend a great deal of effort selecting carrots of various types or of different shapes and sizes. However, with conventional sorting machines, when the type of carrots changes over time or the standard changes, the sorting part has to be largely replaced or the sorting grooves have to be adjusted, which is complicated. Currently, it is not possible to improve the efficiency of sorting work, and producers are currently looking for improved sorting machines that can easily adjust standards.

This invention was made in view of the above circumstances, and allows for easy adjustment of arbitrary specifications according to the type, shape, and size of carrots, further improving the sorting effect and improving work efficiency. The present invention aims to provide an automatic sorting machine for long vegetables such as carrots, which is characterized by being able to maintain market prices.

The present invention will be explained in detail below based on the drawings.

1, 2, and 3 show a side view, a cross sectional view, and a partially enlarged sectional view showing an embodiment of the sorting machine of the present invention. In the drawings, 1 is a main frame, and 2 is a main body frame. Sprocket wheels 2 are arranged facing each other at the top, bottom, left and right corners of the main body frame 1, and each set of two sprocket wheels 2 is arranged facing each other on the left and right, resulting in a total of 4 sets of sprocket wheels 2. 16
Each is provided. For each set of sprocket wheels 2,
A total of four drive chains 4, two of which are driven while being held by chain rails 3, are installed on each side of the main body frame 1, one on the upper side and two on the lower side. . In addition, by chain rail 3,
The roller portion 4a of the chain 4 is supported, preventing horizontal and vertical swing of the chain 4, and preventing horizontal movement.
The movement is smooth. Further, the chain rail 3 located at the end of the main body frame l on the side where the objects to be sorted are inserted (the right end in FIG. 1) is an inclined rail 3a, and has an upward slope in the direction of movement.

As shown in FIGS. 3 and 4, the chain 4 includes:
The fixing plate 6 having a U-shaped cross section is fixed to the plate 5 by bolts 7, and the fixing plate 6 is integrally formed with the plate 5. In addition, the fixed plate 6 is attached to the left and right chains 4.
A large number of them are fixed at appropriate intervals so as to face each other.

A floating plate 8 having a U-shaped cross section is loosely fitted from the outside into each of the facing fixed plates 6 so as to be able to slide up and down. Further, a vertically long long hole 9 is bored in the floating plate 8, and the support shaft 11 of the cylindrical roller 10 is slidably passed through the long hole 9. Nut 1 in hole 12
3, the rollers 10 are installed between the left and right chains 4. A spiral protrusion 14 is formed on the circumferential side of the roller 10 . The protruding strip 14 can be constructed by, for example, a wire lobe inserted into a vinyl tube, wound spirally around the roller 10, and both ends fixed to the circumferential surface of the roller 10 with pins. In addition, on the front and rear sides of the roller 10, there are two sets of vanes 15 and 16, which are long in the axial direction and have a rectangular shape, and one end of which is swingably supported on a support shaft 11 at both ends of the roller 10. Both ends are fixed to the arm plates 17 and 18 of the arm plates 17 and 18, so that the arm plates 17 and 18 are pivotably supported and can extend toward each other's rollers 10. Further, the adjacent end portions of the vanes 15 and 16 are bent in a box shape to prevent the objects to be sorted, such as carrots, from being damaged. The upper ends of each of the two sets of arm plates 17.18 are connected via links 20.21 to convex portions at both ends of a strip-shaped support plate 19 that is fixed to the upper end of the floating plate 8 in a substantially T-shape. and bolts 22 and 23 respectively.
, 24, 25, and arm plates 17, 18, links 20, 21 ., respectively. Four sets of four-bar link mechanisms are formed by the support plate 19 and the fixed plate 6, which is a fixed part. Note that 25' is a ring-shaped base member inserted through the support shaft 11.

Rollers 26 and 27 are supported at both upper and lower ends of each fixed plate 6 via support shafts 28 and 29 (as shown in FIG. 4). As shown in FIG. 2, the rollers 26 and 27 constitute the sorting section 28, and are framed in a C-shape, with two sets facing each other on the left and right sides of the main body frame 1, making a total of four sets. It runs along guide plates 30 and 31 which are divided into appropriate lengths and have a cross-section shaped like a letter L and are fixed to the ends of the adjustment frame 29, which are vertically opposed to each other. Also, adjustment frame 2
Reference numeral 9 denotes a long hole 3 that is vertically bored on both the left and right sides of the main body frame 1.
2. Note that the left and right adjustment frames 29 are equipped with bevel gears 33, which are adjustment devices.
The left and right sets of rotating shafts 35 are screwed to each other and are connected to each other through a pair of rotary shafts 34, thereby making it possible to move up and down.
By moving the adjustment frame 29 up and down with the 6-gauge 9, the left and right sides of the guide plates 30 and 31 can be adjusted up and down integrally, and in this case, the adjacent guide plates 30.
1, sloped portions 30a are formed at the base end portions of the upper guide plates 30, respectively.

Above both left and right ends of the roller 10, there are marks shown in FIGS. 1 and 2.
As shown in the figure, a long and narrow guide having cushioning properties, such as a V-belt, is inserted through a receiving plate 37 having a cross-sectional shape fixed to the lower end of an adjustment rod 36 which is screwed to the main body frame 1 so as to be movable up and down. A plurality of members 38 are mounted along the traveling direction from and in the vicinity of the object-to-be-sorted insertion portion provided with the inclined rail 3a so as to be vertically movable and adjustable by the vertical movement of the adjustment rod 36. The lower ends of the guide members 38 are brought into contact with the circumferential surfaces of the end portions of the rollers 10, and due to the frictional force thereof, the rollers 10 are moved by the drive of the chain 4, and the rollers 1O are rotated.

In addition, the first insertion portion, which extends upward from near both ends of the roller 10 and through which the objects to be sorted pass,
A plate-shaped drop-off prevention plate 39 has a length from 1 to the final end.
It is fixed to the main body frame 1 via a fixture 40.

Each sorting section 28 and the tip (left end in FIG. 1)
As shown in FIG. 1, FIG. 2, and FIG.
A brush 41, which is a receiving means in which bristles 41b are long and divided in the axial direction, is installed via a support shaft 42, and is rotationally driven by a driving means (not shown).

Further, as shown in FIG. 1, a conveyor 43 serving as a carrying-out means is provided below each of the sorting sections 28 and the brush 41 at the final end. The items to be sorted can be separated and taken out.

Since the sorting machine according to this invention is as described above,
To carry out the sorting work, first, the objects A to be sorted, such as carrots, are moved by an insertion conveyor 44 for inserting objects to be sorted shown in FIG. It is placed on top of 10. As shown in FIG. 6, the roller 10 is moved in the direction indicated by the arrow in the same figure as the chain 4 is rotated, and when the roller 10 is brought into contact with the guide member 38 and rotated, the spiral of the roller 10 is rotated. One end of the object A to be sorted is sent to one end of the roller 1o by the shaped convex strip 14, and even if it is placed so that it becomes long in the direction orthogonal to the axial direction of the roller 10, it can be easily moved in the axial direction of the roller 10. The direction is changed parallel to . and,
It is placed so as to straddle the wing plates 15 and 16 that are adjacent to each other.

When the roller 10 is moved and moved to the sorting section 28, as shown in FIG. 7, the height of the adjustment frame 29 (shown in FIG. 2) can be adjusted to an arbitrary height by rotating the rotating shaft 35 with a handle or the like. By following the guide plates 30 and 31 which are set at an arbitrary height, the rollers 26 and
is set to an arbitrary height. At this time, as shown in FIG. 4, when the rollers 26 and 27 are adjusted to an arbitrary height by the guide plates 30 and 31, the floating plate 8 is moved downward along the fixed plate 6, The lowering of the floating plate 8 also causes the vanes 15, 16 to swing downward via the links 20.21. Then, as shown in FIG. 7 again, each sorting section 28
The heights of the guide plates 30, 31 of the vanes 15. By changing the rocking angle of i6, adjacent blades 15
, 16 can be set to, for example, S, M, and L as shown in the figure. The objects to be sorted held between adjacent blade plates 15 and 16 are those whose maximum diameter is less than S, those between S and M, those between M and L, and those whose maximum diameter is L or more. Objects can be sorted into four stages, and the sorted objects are dropped onto a conveyor 43 and taken out one stage at a time. Incidentally, the sorting stage can be made into any stage by increasing the number of sorting sections 28.

The sorting machine according to this invention is as described above.
1 ah, ka 18, ka. Isanyu. □One item can be automatically and continuously sorted into several types of standards. Furthermore, even when changing the standard, the spacing between adjacent vanes 15, 16 can be changed by simply adjusting the adjustment device of each sorting section 28 with a handle or the like and adjusting the height of the guide plate 30, 31. , thereby making it easier to change the sorting standard. Further, the objects to be sorted, such as carrots, which have been sorted and dropped, are received by a brush 41, which is a receiving means, and then placed on a conveyor 43, which is a carry-out means, and taken out on the standard side, so that there are no scratches or the like on the objects to be sorted. This has the advantage that it can be easily taken out and transported to the next process without being attached.
