(Prior art) The weighing means in a sorting machine for bulk agricultural products such as apples, tangerines, and potatoes is to screw a weight onto the rear end of a horizontal rotating rod and move the weight along the rotating rod. Therefore, the set weight was changed by changing the rotational moment length due to the weight of the weight.

(Problem to be solved by the invention) However, with the above conventional weighing means, it takes a lot of effort and time to set or change the set weight using a weight, and it is difficult to grasp the set weight.
There was also the problem that it was difficult to weigh accurately.

Therefore, in view of the above-mentioned problems in the conventional agricultural product sorting machine, the present invention applies the solution to this problem to the flower sorting machine, and makes it possible to easily set or change the weight set by the weight, and to change the value. Easy to understand,
Moreover, it is an object of the present invention to provide a flower sorting machine that can accurately weigh flowers.

(Means for Solving the Problems) For this purpose, the present invention includes an endless rotating chain 9 and a rotating rod 1 rotatably installed on the endless rotating chain 9.
5, a support arm 16 for the flowers 32 which are arranged in parallel with the rotary rod 15 and are transported by the endless rotary chain 9; A guide rail 4 that slides and guides the slider 1 that protrudes from one end, and a weight 7 that is disposed on the side of the conveyance path and is attached to the rear end of the rotary rod 6.
The weighing device 3 of the support arm 16 is equipped with a
5, the rotary rod 6 is
A tip 6a is disposed parallel to the guide rail 4 to complement the notch 34 of the guide rail 4, and extends from the tip 6a to the outside of the guide rail 4 and is rotatable around the fulcrum 21. It is composed of a central part 6b that is pivotally supported by a central part 6b, and an upright part 6c that stands upward from the rear end of this central part 6b, and the weight 7 is detachably attached to this upright part 6c from above. This is what I did.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 3 is a side view of a flower sorting machine, which is composed of a sorting section that weighs and sorts flowers 32, and a supply section that supplies flowers 32 such as electric chrysanthemums to this sorting section. There is. The supply unit is composed of a plate-shaped supply table 29, which is provided obliquely with a downward slope toward the conveyance direction.

In the sorting section, a large number of rod-shaped support members 13 are installed at pitches on the endless rotary chain 9, and a rotary rod 15 is rotatably mounted on the support portions 14 erected at both ends of the support members 13. Support this rotating rod 15,
It is constructed by arranging a plurality of support arms 16 in parallel on which the flowers 32 are supported, and the support arms 16 are transported to the endless rotation chain 9 and circulate through the transport path (first
(See also figure).

As shown in FIG. 1, the distal end of the support arm 16 is attached to the rotary rod 15, and is bent rearward (in the direction opposite to the conveying direction) into a substantially V shape from this attached portion to support the flower 32. The stem is positioned in the deepest part 16c of this approximately V-shaped recess formed by the central part 16a and rear end part 16b of the support arm 16 so as not to shake.

In FIG. 1, reference numeral 4 denotes a guide rail disposed parallel to the endless rotary chain 9 and attached to the support frame 8 by a mounting bracket 27, and is attached to one end of the rotating rod 15. In addition, the slider 1 protruding from the corner of a substantially long flat plate 17 is slidably guided. A notch 34 is formed on this guide rail 4 to partially cut it out, and the starting end of the guide rail 4 that is continuous with this notch 34 becomes a conical part 5 with a pointed tip. ing.

Further, the slider 1 is attached to a flat plate 17 by a pin 18, a spring 19, and a stopper 20, and a tapered surface 2 that slopes downward in the conveying direction is formed at the top end of the slider 1 (a first (See Figure and Figure 2). 25 is a screw rod attached to the flat plate 17, and 24 is an adjustable balance weight for the weight of the starting end side of the rotating rod 15 including the support arm 16, the flat plate 17, etc., and is screwed to the end of the screw rod 25. has been done. 26 is a stopper supporting the lower surface of the flat plate 17.

Further, a weighing device 35 for the support arm 16 is disposed on the side of the conveyance path, and this weighing device 35
is constructed by attaching a weight 7 to the rear end of a rotating rod 6. Furthermore, this rotary rod 6 has a tip 6a disposed parallel to the guide rail 4 so as to complement the notch 34 of the guide rail 4, and extends from the tip 6a to the outside of the guide rail 4. and a central portion 6b rotatably supported on the fulcrum portion 21.
It is formed of an upright portion 6c that stands upwardly from the rear end of the central portion 6b, and the weight 7 is removably attached to this upright portion 6c from above. That is, it is possible to attach any combination of weights having various weights to the upright portion 6c. For example, as shown in FIG. can do. In addition, in this weighing device 35, since the upright part 6c is upright, the distance from the fulcrum part 21 to the force point part to which the weight 7 is attached (the position of the upright part 6c) is determined by the weight of the weight 7. The rotational moment length L is constant, so accurate weighing is possible.

With the slider 1 transferred from the guide rail 4 to the tip 6a bent in a fold-back shape (solid line position in FIG. 2), with the rotation rod 15 as the center of rotation,
Further, if the weight moment on the support arm 16 side with the slider 1 as the point of action is larger than the weight moment set by the weight 7 etc., the rotating rod 6
The weight 7 rotates in the direction of flipping up the slider 1 (the chain line position in the figure), the slider 1 loses its support, the support arm 16 rotates downward, and the flowers 3 loaded on it rotate.
2 is fall sorted. Further, as described above, by forming the tapered surface 2 at the top end of the slider 1, and by making the starting end of the guide rail 4 continuous with the notch 34 into the conical part 5, the tip 6a of the rotating rod 6 is formed. When the slider 1 transferred to the slider 1 descends after weighing, there is no risk of contacting the conical part 5 and damaging it. Furthermore, when the slider 1 is slightly lowered, the tapered surface 2 of the slider 1 is distributed vertically by the conical portion 5, so there is no risk of contacting or getting caught. Therefore, accurate weighing and sorting is possible.

In FIG. 3, 28 is a cutter disposed on the side of the conveyance path, and cuts the base end of the stem of the flower plant 32 loaded on the support arm 16 and conveyed.
This is to make the lengths of the flowers 32 uniform. That is,
Flowers 32 supplied one by one to the support arm 16
are cut by the cutter 28 to have the same length, and then weighed by the weighing device 35. 30 is a conveyor for carrying out the flowers 32, and 31 is a prime mover.

This flower sorting machine has the above-mentioned configuration, and the overall operation will be briefly explained next.

The flowers 32 are transferred from the supply stand 29 to each support arm 16.
The recesses 16a and 16b are supplied one by one to the deepest portions 16c of the recesses 16a and 16b, and are correctly positioned. These support arms 16 are conveyed by the endless rotation chain 9, and when the flowers 32 reach the cutter 28,
The proximal end of the stem is cut to equalize the length of the flower plant 32. Thereafter, the slider 1 protruding from one end of the rotary rod 15 on which the support arm 16 is arranged side by side slides on the guide rail 4 and is transferred to the tip 6a of the rotary rod 6. Weighing is performed in this state, and if the weight moment on the support arm 16 side with the rotating rod 15 as the center of rotation and the slider 1 as the point of action is smaller than the moment of the weight set by the weight 7, it will slide on the guide rail 9 as it is. Then, the weight is transferred to the next weighing device and weighed again using a lighter weight than the previous one. In this way, the flowers 32 are dropped and sorted in descending order of weight.

(Effects of the Invention) As explained above, the present invention provides the rotary rod 6 of the weighing device 35 with the tip portion 6a disposed parallel to the guide rail 4 so as to complement the notch 34 of the guide rail 4. , a central portion 6b extending from the tip portion 6a to the outside of the guide rail 4 and rotatably supported on the fulcrum portion 21; and an upright portion 6c erected upward from the rear end of the central portion 6b. The weight 7 is detachably attached to the upright portion 6c from above, so that by freely combining weights having various weights and attaching them to the upright portion 6c, the weight 7 can be attached to the upright portion 6c. To easily set or change a set weight, and to know the set weight. Moreover, in this case, since the distance from the fulcrum part 21 to the point of effort to which the weight is attached, that is, the rotational moment length due to the weight of the weight, is constant, accurate weighing is possible.
