Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rod-shaped agricultural product sorter, and more particularly, to a rod-shaped agricultural product sorter that removes an insufficient amount of agricultural products in advance and then sorts the agricultural products by weight.

[0002]

[Prior art]

 Generally, the heavier the flowers such as chrysanthemums, the better they are, and the weight selection is performed before shipping. However, in the case of flowers, even if they have a certain weight, if the length is shorter than the set dimension, they are not necessarily good products, and the flowers that are not so large may have to be selected separately. Therefore, the applicant of the present invention has proposed a sorter which removes a flower of a size smaller than a predetermined size in advance, prior to weighing and selecting the flower (Japanese Utility Model Publication No. 3-56304). This product is provided with a lever (reference number is for public notice) in the transportation path of the flower, and if the flower does not hit the lever 4, the flower is not transported to the weighing machine 32 and falls in front of it. It is designed to be removed.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional means has a problem that the structure of the transmission 35 shown in FIG. 1 is considerably complicated. In addition, a defective defective flower is dropped in front of the weighing means 32. However, if the drop collection space for defective defective flowers is provided in front of the weighing means 32, the length of the flower selecting machine becomes long. As a result, the size of the device was increased, and the collection of the flowers that fell before this was troublesome. Therefore, an object of the present invention is to provide a sorter that can easily remove defective products that are not too small when weighing and sorting rod-shaped agricultural products such as flowers, and that can be compactly configured as a whole.

[0004]

[Means for Solving the Problems]

 To this end, the present invention is provided with a detection means 12 for detecting an insufficient agricultural product P supported by the support 4 upstream of the weighing means 30A to 30C, and at the same time, to a first parallel to the first guide rails 211 to 214. The second guide rail 20B and the switching means 50 for switching the sliding path of the slider 16 to the first guide rail 211 or the second guide rail 20B based on the detection result of the detection means 12 are provided to the detection means 12. The insufficiently-sized agricultural product P thus detected is conveyed along the second guide rail 20B without being weighed by the weighing means 30A to 30C and is carried out to the terminal end side of the second guide rail 20B. It was done like this.

[0005]

[Action]

 According to the above configuration, a defective product that is not too small can be removed in advance before weighing and sorting the rod-shaped agricultural products. In this case, the defective agricultural product does not fall in front of the weighing means 30, but is transported to the downstream side as it is and falls on the downstream side of the weighing means 30. Therefore, there is no need for a space for collecting defective products inside the sorter, the entire length can be shortened to make it compact, and the collected defective products can be collected easily.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings, using a sorting machine for sorting flowers by weight as an example. FIG. 1 is a side view of the sorter. Reference numeral 1 denotes an endless rotation band composed of an endless rotation chain, which is adjusted by a sprocket 2 and is driven by a motor 3 to rotate in the arrow direction. The supports 4 of the flower P are attached to the endless rotation zone 1 at a pitch. The support 4 of this embodiment is formed by bending a steel wire into an arm shape, but the shape and structure of the support is changed according to the agricultural product to be selected. 10 is a supply table, and the flowers P on this table 10 are loaded on the support 4 one by one.

FIG. 2 shows a mounting structure of the support 4. Reference numeral 5 is an attachment plate fixed to the endless rotation belt 1, and 6 is a horizontal rod whose both ends are pivotally attached to the attachment plate 5 and which rotates about its axis. The base end portion of the support body 4 is attached to the horizontal rod 6 by a stopper 7.

In FIGS. 1 and 2, a long frame 11 is arranged above the conveying path formed by the endless rotation band 1. A touch sensor 12 is attached to the frame 11. A lever 12a is vertically provided from the sensor 12 and the flower P is detected when the lever 12a contacts the flower P. If the lever 12a does not detect the flower P, this flower P is a non-defective product that does not have a standard length, and is provided at the rear of the sorter without weighing by the weighing means 30 as described later. It is conveyed to the collecting section 13D and collected. It should be noted that the flower P detecting means is not limited to such a touch sensor 12, and an optical element such as a light emitting element or a light receiving element can be applied. In FIG. 1, a plurality of trough-shaped collecting parts 13 (13A, 13B, 13C) are provided below the conveying path, and the flower P selected by means described later falls into the collecting part 13.

Next, the structure of the slider guide means will be described. In FIG. 2, a plate 15 is fixed to an end portion of the horizontal rod 6, and a strip-shaped slider 16 is fixed to the plate 15. The slider 16 slides on a starting end guide rail 20A arranged in parallel with the endless rotation band 1. 17 is a balance weight. A guide path switching means 50 for the slider 16 is provided at the terminal end of the starting guide rail 20A. The switching means 50 is a guide plate 51 that is a guide means at the same level as the starting end guide rail 20A, a base plate 52 that extends laterally from the guide plate 51, and two standing plates on the base plate 52. Pin 53 and the solenoid 54, and the rotary arm 54 a of the solenoid 54 is located between the pins 53. As the drive means of the switching means, a motor, a cam, a link mechanism, etc. can be applied in addition to the solenoid.

In FIG. 2, a start guide rail 20 A and a second guide rail 20 B at the same level as the guide plate 51 are provided downstream of the guide plate 51. As shown in FIG. 1, the end portion 20Ba of the guide rail 20B extends to the end of the conveying path of the endless chain 1, and a collection portion 13D for collecting a small flower P is provided below the end portion 20Ba. With this configuration, it is possible to provide the collecting unit 13D for dropping the flower P of the defective product, which is not so large, to the outside of the rear of the sorting machine, and collecting the defective product inside the sorting machine as in the conventional means. No space is required, and the overall length of the sorting machine can be shortened to make the entire system compact.

In FIGS. 1 and 2, below the guide plate 51 and the second guide rail 20 B, a first guide rail 21 (211, 212, 213, 214) parallel to the second guide rail 20 B is provided. ) Is provided. A weighing means 30 (30A, 30B, 30C) is provided between the guide rails 211-214. The weighing means 30 is composed of a rotary rod 31, a weight 32 loaded on the rear end of the rotary rod 31, a pin 34 and a frame 33 for pivotally supporting the rotary rod 31, and the like. The tip portions 311a, 311b, 311c are bent so as to be parallel to the first guide rails 211 to 214. This weighing means 30 can change the set weight by replacing the weight 32. Further, as shown in FIG. 1, recovery parts 13A, 13B, 13C are provided below the weighing means 30A, 30B, 30C. A box, chute, unloading conveyor, or the like can be applied as the collecting units 13A to 13D.

Although the guide plate 51 is normally in the position shown by the solid line in FIGS. 2 and 4, when the lever 12a of the sensor 12 detects the flower P, the solenoid 54 is driven to move the arm 54a to the position shown in FIG. At, the guide plate 51 is retracted to the position shown by the chain line in FIG. Then, the slider 16 sliding on the starting end guide rail 20A cannot be transferred to the guide plate 51, and drops onto the first guide rail 211 in the lower stage to be transferred. Further, when the lever 12a of the sensor 12 does not detect the flower P, the guide plate 51 holds the position shown by the solid line in FIGS. Then, the slider 16 sliding on the starting end guide rail 20A is transferred to the guide plate 51 as shown by an arrow N1 (FIG. 2) and further transferred to the second guide rail 20B. This sorter has the above-mentioned configuration, and the overall operation will be described below.

In FIG. 1, the supports 4 on which the flowers P on the table 10 are loaded one by one move to the right. Here, if the flower P is not detected by the lever 12a of the sensor 12, the flower P is a defective product that is not so small, and in this case, the solenoid 54 does not operate and the guide plate 51 as shown in FIG. Holds a position that complements between the starting end guide rail 20A and the second guide rail 20B. Therefore, the slider 16 moves from the starting end guide rail 20A to the guide plate 51 as shown by an arrow N1, slides on the guide plate 51, moves to the second guide rail 20B, and moves to the downstream side. Then, the slider 16 falls off from the terminal end portion 20Ba of the guide rail 20B, the support 4 rotates downward, and the flower P is dropped and collected in the collecting portion 13D provided outside the sorting machine.

Further, when the flower P is detected by the lever 12a of the sensor 12, the flower P has a standard length. In this case, the solenoid 54 is activated by a signal from the sensor 12, The arm 54a rotates and the guide plate 51 retracts to the position indicated by the chain line in FIG. Then, as shown by an arrow N2 in FIG. 3, the slider 16 falls from the starting end guide rail 20A onto the lower guide rail 211, is transferred, and slides to the right. Then, it is transferred to the tip portion 311a of the rotary rod 31 of the first weighing means 30A, but when the flower P has a weight set by the weight 32, the tip portion 311a descends due to the load (see the chain line in FIG. 3). ), The slider 16 cannot be transferred to the next guide rail 212 and falls off the tip portion 311a, and this flower P falls on the first collecting portion 13A.

When the flower P is lighter than the set weight of the first weighing means 30A, the slider 16 is transferred from the tip portion 311a to the guide rail 212 as shown by an arrow N3, and then the second weighing means. The above operation is repeated by transferring to the tip portion 311b of the rotating rod 31 of 30B, and when it has a set weight, it falls to the second collecting portion 13B. When the weight is smaller than the set weight of the second weighing means 30B, the slider 16 moves to the third weighing means 30C as indicated by the arrow N4. The set weight of the third weighing means 30C is set to zero, and all the flowers P fall into the third collecting section 13C. Although the above embodiment has been described by taking the floriculture as an example, the sorting machine of the present invention can also be applied as a sorting machine for rod-shaped agricultural products such as burdock.

[0016]

[Effect of device]

 As described above, according to the present invention, it is possible to automatically remove inadequate defective agricultural products in advance, and to sort only those having a standard size by weight. However, since the defective product collection space can be provided outside the rear of the sorter, the total length of the sorter can be shortened to make the whole compact, and the collected defective products can be easily removed.
