And a pair of inner side plates facing each other in the depth direction (not shown). A transport unit 20 described later is arranged on a left side portion of the storage unit 10 facing the right side plate 13. The storage unit 10 is formed in a container shape by these configurations,
It is partitioned and the rod can be stored inside the partitioned.

The bottom plate 12 is located on the right side plate 13 in the height direction.
The side is high and the conveying unit 20 side is low. The rods stored in the storage unit 10 due to this inclination gather on the transport unit 20 side. In particular, when the remaining rods in the storage unit 10 are small, the rods gather on the transport unit 20 side. Therefore, the rod can be naturally guided to the transport unit 20. Also,
The bottom plate 12 has a plurality of small holes 12a and is formed in a so-called punching shape. Since the rod inserted from the rod insertion port 4 is washed in the water tank 2 and wet, the rod can be drained by providing the small holes 12 a in the bottom plate 12. In addition, although not shown in FIG.
A drainage mechanism for draining the water cut by the bottom plate 12 is provided below the bottom plate 12.

The transport unit 20 includes a first roller 21, a second roller 22, and a third roller 2 rotatably supported.
3. A drive mechanism 27 for rotating the endless transport belt 24 wound around the three rollers and the first roller 21 is provided. The transport belt 24 is rotated in the transport direction A by the drive mechanism 27. Conveyor belt 24
Are provided with a plurality of guide plates 25 standing substantially vertically. The guide plate 25 is formed in a plate shape, and is set so that the height from the outer peripheral surface of the transport belt 24 is substantially equal to the thickness of the rod having the maximum diameter. The width between the guide plate 25 and the adjacent guide plate 25 is set so as to accommodate one or two rods.
The longitudinal direction of the rod is parallel to the plane of the guide plate 25 in a space formed between the guide plate 25 and an adjacent guide plate 25 (hereinafter, referred to as “accommodation space 26”). Is accommodated and transported.

The first roller 21 is connected to the bottom plate 1 of the storage section 10.
2 and slightly obliquely downward and to the left, and at a position where the distance between the lower end of the bottom plate 12 and the outer peripheral surface of the conveyor belt 24 is slightly longer than the height of the guide plate 25. The second roller 22 has a central axis substantially at the upper end of the right side plate 13 of the storage unit 10 in the height direction, and slightly to the left from a vertical line L passing through the central axis of the first roller 21. Is set at a position apart from.

The third roller 23 is installed at a position separated by a predetermined distance horizontally leftward from the installation position of the first roller 21. The conveyor belt 24 forms the following parts depending on the installation positions of the rollers. That is, a vertical portion 24a between the first roller 21 and the second roller 22 where the transport belt 24 is stretched in a substantially vertical direction,
An inclined portion 2 between the second roller 22 and the third roller 23 where the conveyor belt 24 is gently inclined and stretched.
4b, a horizontal portion 24 between the third roller 23 and the first roller 21 where the transport belt 24 is stretched in the horizontal direction.
c.

The vertical portion 24a is arranged facing the storage section 10. Therefore, the rods stored in the storage unit 10 can be sequentially taken out. FIG.
FIG. 8 is a view for explaining an operation when the rod moves to the storage space 26 of FIG. When the transport belt 24 is driven in the transport direction A by the drive mechanism 27, the transport belt 24 moves upward (see arrow B). At this time, the storage unit 10
The inner rod is guided along the inclined bottom plate 12 (see arrow C) and is accommodated in the accommodation space 26. The accommodated rod is conveyed upward along with the movement of the conveyance belt 24.

The vertical portion 24a is inclined so as to slightly fall to the left. Therefore, the rod does not fall from the storage space 26 during the upward movement of the vertical portion 24a. Note that the inclination of the transport belt 24 in the substantially vertical direction is desirably steep so that the longitudinal direction of the rod is hooked on the guide plate 25 and is not transported across the guide plate 25.

Returning to FIG. 2, the rod accommodated in the accommodation space 26 is placed on the upper surface of the guide plate 25 and transported upward. The direction in which the rod is conveyed along the peripheral surface of the second roller 22 is changed, and the rod is conveyed to the lower left position by the inclined portion 24b between the second roller 22 and the third roller 23. . The second roller 22
Is displaced in the vertical direction, so that the tension of the transport belt 24 can be adjusted.

The sorting section 30 includes an opposing plate 32 provided so as to oppose the peripheral surface of the third roller 23, and a third roller 2.
Between the third roller 21 and the first roller 21, a sorting plate 31 provided substantially in parallel below the horizontal portion 24 c, which will be described later.
A push-up mechanism 33 for pushing up a rod sandwiched between slits of the sorting plate 31 is provided. The opposing plate 32 is formed in a concave curved surface shape, and the distance between the outer peripheral surface of the conveyor belt 24 and the surface of the opposing plate 32 at this curved surface portion is determined by the guide plate 2.
It is set slightly longer than the height of 5. With these configurations, the rod is smoothly guided to the sorting plate 31 without being clogged in the opposing plate 32.

Slits 34 are formed in the sorting plate 31 at regular intervals in the left-right direction, and each slit 34 extends in the depth direction. Each slit 34 has a width corresponding to the thickness of the rod, and the slit 3 formed on the right side.
The width is made wider by about four. Inclined part 2
The rod transported 4b is transferred to the sorting plate 31 along the opposing plate 32. That is, since the leading end of the guide plate 25 of the conveyor belt 24 faces downward along the peripheral surface of the third roller 23, the rod is moved from above the guide plate 25 surface.
It rolls on the opposing plate 32 and the sorting plate 31. Sorting plate 3
The rod rolled on 1 is transported along the transport direction A so as to be rolled on the sorting plate 31 by the guide plate 25. At this time, the rod falls downward from the slit 34 having a width corresponding to its thickness. Thus, the rods can be sorted according to the thickness.

FIG. 5 is a diagram for explaining the operation when the rod is transported on the sorting plate 31. When a rod Ra having a thickness that can be dropped from the slit 34 is conveyed on the sorting plate 31, the rod Ra falls from the slit 34a. On the other hand, a rod R thicker than the width of the slit 34a
b is conveyed, the rod Rb is placed in the slit 3
4a, and is conveyed toward the next slit 34b. Here, the thickness of the rod Rb is the slit 34b.
When the rod Rb is narrower than the width of the slit 34b,
Fall from.

When a rod Rc having a width larger than any of the slits 34a and 34b is conveyed, the rod Rc is conveyed as it is without dropping from any of the slits 34a and 34b. As described above, since the rod falls down from the slit 34 by the slit 34 having a width corresponding to the thickness of the rod, the rod can be sorted according to the thickness of the rod.

In the sorting plate 31 of this embodiment, a pair of slits 34 having the same width are formed continuously. This is the same width slit 3 of one rod
This is because the opportunity to fall from the number 4 is provided twice. Therefore, the accuracy of rod selection can be improved. By the way, as shown in FIG. 6A, in the case of a rod whose thickness is one size larger than the width of the slit 34, for example, about 1/3 of the rod may be caught in the slit 34. Even if it is pushed by the guide plate 25, the pinched rod cannot come out of the slit 34 as it is, which may cause abnormal noise or may hinder the selection of a subsequent rod by the pinched rod.
In response to such a case, a rod sandwiched between the slits 34 is again placed on the sorting plate 31 in the sorting unit 30.
A push-up mechanism 33 is provided so as to be conveyed.

Returning to FIG. 2, the push-up mechanism 33 includes the sorting plate 3
Sliding plate 33a slidably provided along the lower surface of
, A motor 33b, and a conversion member 33c which is attached to the slide plate 33a integrally with the slide plate 33a and converts the rotational motion of the motor 33b into a linear motion. In the sliding plate 33a, the same number of slits 36 as the number of slits 34 of the sorting plate 31 are formed at regular intervals in the left-right direction,
Each slit 36 extends in the depth direction. Each slit 36 is provided so as to face each slit 34 of the sorting plate 31, and the width of each slit 36 is
Is formed to be slightly wider than the width of the slit 34.

The conversion member 33c converts the rotational movement of the motor 33b into a linear movement using, for example, a cam. Therefore, when the motor 33b is driven, the sliding plate 33a is reciprocated along the bottom surface of the sorting plate 31 for a predetermined distance by the converting operation of the converting member 33c. FIG. 6 is a diagram for explaining an operation of pushing the rod sandwiched between the slits 34 back onto the sorting plate 31.

When the rod is caught in the slit 34 (see FIG. 6A), one side of the sliding plate 33a pushes up the rod by displacing the sliding plate 33a in the horizontal direction (see arrow D). See FIG. 6 (b)). Thereby, the rod moves upward. The pushed-up rod is guided by the guide plate 25.
And can be conveyed again on the sorting plate 31. In this manner, the rod sandwiched between the slits 34 can be pushed back onto the sorting plate 31.

Returning to FIG. 2, on the other hand, the rods which did not fall from any of the slits 34 in the sorting unit 30 are connected to the connecting plate 37 connecting the sorting plate 31 and the bottom surface 12 of the storage unit 10 along the transport direction A. Conveyed. The rod lifted by the guide plate 25 along the connection plate 37 is circulated again in the transport direction A. If the slit 34 closest to the connection plate 37 has an extra-large width, the rod that has not fallen in the slit 34 so far can be surely dropped into the storage container 9e corresponding to the slit 34 without circulating. Can be.

The connection plate 37 is formed in a concave curved surface shape. The distance between the outer peripheral surface of the conveyor belt 24 and the surface of the concavely curved connecting plate 37 is set slightly longer than the height of the guide plate 25. With such a configuration, a rod that has not fallen from the slit 34 in the sorting unit 30 can be smoothly guided without being clogged. In the storage unit 9,
Storage containers 9a to 9 provided corresponding to each slit 34
e is provided. The rods selected by the slits 34 fall from the slits 34 and are stored in the storage containers 9a to 9e. Therefore, the rod can be stored in the storage containers 9a to 9e according to the external dimensions.

A plurality of guide plates 41 for guiding the rods to the storage containers 9a to 9e are provided between the selection plate 31 and the storage containers 9a to 9e. The rod that has fallen downward from the slit 34 is guided along the guide plate 41 and is stored in the storage containers 9a to 9e. Therefore, compared with the case where the guide plate 41 is not provided, the space in which the storage unit 9 is provided can be increased, and therefore, the sizes of the storage containers 9a to 9e can be increased.
