Description

[Detailed description of the invention] This invention is a sorting object supply device used in a sorting conveyor that sorts round objects such as Satsuma oranges, navels, pears, and apples into multiple classes according to size according to standards, etc. It is related to.

Conventionally, a plurality of receiving plates having screening holes are stacked one on top of the other. While the stack is being transferred, the receiving plates in the screening holes of the stack are rotated downward at different positions in order from the bottom receiving plate with the smallest screening hole. A sorting conveyor is used that sorts items by size.

However, since this sorting conveyor simply uses a roller conveyor or the like as a supply device for the sorted objects to drop and supply the objects to be sorted onto the top surface of the stacked bodies of the sorting conveyor, the stacked objects that move the sorted objects cannot be used. Because of this, the objects to be sorted cannot be inserted quickly and positively into the sorting holes, and as a result, the objects to be sorted are transferred while remaining on the top surface of the stack without entering the sorting holes, or two objects to be sorted are inserted into one sorting hole. There is a problem that not only accurate sorting cannot be carried out, but also the objects to be sorted cannot be positively and efficiently introduced into the sorting holes, so that efficient sorting cannot be performed.

Therefore, in the present invention, partition plates are provided to guide the objects to be sorted, which are dropped from the supply conveyor that supplies the objects to the sorting conveyor, onto the transfer path of the sorting holes in the stack. A sorted object that solves the above-mentioned drawbacks at once by providing a scraping plate in contact with the object to fit the object into the sorting hole so that the object to be sorted can be reliably and efficiently fitted into the sorting hole. The purpose is to provide a material supply device.

The width of the third guide rods 5c and 5c is set to be such that they can engage with the lower surfaces of the protruding pieces 9b and 9b on both left and right ends of the second receiving plate 5b, and similarly, the third guide rods 5c and 5c are respectively engaged with the protruding pieces 9c and 9c of the third receiving plate 3c. The width is set to fit.

15 is a supply device for the materials to be sorted, and in this supply device, 16 is a roller conveyor, and a pair of left and right chenographs 18
, 18 is constructed such that a roller 20 is driven by an appropriate driving means on the outer periphery of a bar 19 installed between the rollers 18 and 18. The objects to be sorted are transferred forward and at the same time are spread laterally so that they are uniformly spread and transferred.

Reference numeral 21 denotes a supply vibration conveyor connected to the roller conveyor 16, and a pair of inclined springs 25 protrude from a base 24. Attached to the upper end of .25, transfer plate 2 described above.
A vibration generating body 26 constituted by a vibration motor or the like is attached to the lower surface of the machine 3, so that the objects to be sorted on the transfer plate 23 are transferred in the direction of the arrow Y.

Reference numeral 27 denotes a feeding mechanism for sequentially dropping and supplying the objects 2 to be sorted discharged from the vibrating conveyor 21 to each stacked body 3 of the sorting conveyor 1. A pair of arms 30, 30 are planted on the left and right between the divided bodies 29, 29 at positions facing each groove 22, 22..., and the arms 30, 30 of each set are planted at equal quarter positions. 30°30 is tilted so that the distance gradually expands to the left and right as it goes toward the tip.

When the rotating shaft 28 rotates in the direction of the arrow X, the transfer plate 2
The objects to be sorted on 3 are scooped up by arms 30 and 30 and dropped forward.

In this case, the rotating shaft 28 rotates in order to adjust the supply timing approximately corresponding to the sorting hole of each stacked body 3.

Reference numeral 31 denotes a rubber regulating plate, which guides the objects to be sorted falling from the feeding mechanism 27 downward so that they do not fly forward.

The laminates 3 are provided between the respective transfer paths of the respective sorting holes of the laminated body 3 at the supply position P where they are dropped and fed from the feeding mechanism 27 of No. 5, and correspond to each other on the left and right with the transfer path K in between.

Reference numeral 33 denotes a scraping plate made of rubber, which is hung between each partition plate 32 with its upper end supported by a frame W, so that it comes into contact with the object to be processed on the upper surface of the laminate 3 and falls into the sorting hole. I have to.

The operation of the sorted material supply device configured as described above will be explained.

When the object 2 to be sorted is scooped up by the arm 30.30 of the feeding mechanism 27 from the vibrating conveyor 21 of the supply device 15 and falls, it is guided by the arm 30.30 and descends, but this arm 30.30 goes to the tip. Since the distance between the support positions of both arms increases as it descends along the arms 30 and 30, stability increases, so even deformed objects can be sorted on the side of the arms 30 and It falls straight and accurately toward the middle of the arms 30 and 30 without falling off in any direction.

The fallen objects to be sorted are guided by the partition plate 32, so that they fall upward onto the transfer path of the sorting holes on the sorting conveyor 1 without jumping forward.

While the object 2 to be sorted is being transported together with the stack 3, it comes into contact with the scraping plate 33 as shown in FIG. 7, and its movement is blocked to some extent, so that it is decelerated and falls into the subsequent sorting hole.

Once the object 2 to be sorted has completely fitted into the sorting hole, it will not escape from the sorting hole even if it is subjected to movement prevention action by the scraping plate 33, and will be transported together with the stacked body 3.

Furthermore, when two objects are fitted into one sorting hole, the fitting is incomplete and one or both objects are pushed out by the scraper plate 33 and fall into the subsequent sorting hole. It will be done.

The objects to be sorted thus fitted into the sorting holes of the stacked body 3 are transported forward.

Then, when the cargo 3 passes over the first guide rod 5a, the downward motion restraining action of the protrusions 9a, 9a on both sides of the first receiving plate 3a at the lowest position by the first guide rods 5a, 5a is released, and The first receiving plate 3a rotates downward around the shaft 8 due to its own gravity, and objects to be sorted smaller in size than the second sorting hole 10b of the second receiving plate 3b pass through the second sorting hole 10b and pass through the second sorting hole 10b. It rotates downward together with the receiving plate 3a.

During the rotation, the objects to be sorted on the first receiving plate 3a are
It falls from the receiving hole 3b.

The fallen small-sized objects to be sorted are sent out laterally by a discharge belt conveyor 40.40.

Subsequently, the objects to be sorted that are larger than the second sorting hole 10b are further transferred forward together with the stacked body 3, and the second receiving plate 3b is removed from the second guide rod 5b.

Therefore, the second receiving plate 3b rotates downward, and at this time, medium-sized objects smaller than the third sorting hole 10c are removed from the second sorting hole 10c.
0b and moves downward, and large objects to be sorted that are larger than the third sorting hole 10c remain on the third receiving plate 3c.

The medium-sized objects to be sorted that fit into the second sorting hole 10b and move downward will surely fall due to their own weight by the time the second receiving plate 3b reaches the lowest part.

The fallen medium-sized objects are transferred to the discharge belt conveyor 41.
．． 41, it is sent out to the side.

Subsequently, the large-sized objects to be sorted, which are larger than the third sorting hole 10c, are further transferred forward together with the stacked body 3, and are transferred to the third receiving plate 3.
c comes off from the third guide rod 5c.

Then, the third receiving plate 3c rotates downward. The large-sized objects to be sorted that fit into the third sorting hole 10c and move downward are placed in the third sorting hole 10c.
By the time the receiving plate 3c reaches the bottom, it will surely fall under its own weight.

The large-sized items that have fallen are transferred to a conveyor 42 to a discharge bell.
．． 42, it is sent out sideways.

In the above embodiment, the scraping plates were made of rubber, but as shown in FIG. 8, scraping plates 3, 3' are made of hard plates whose upper ends are rotatably suspended from the frame W via a hinge T. may be used.

As shown in the above embodiments, the object supply device for sorting conveyors for fruits, etc. of the present invention has sorting holes in the stack at the position where the objects to be sorted are dropped and fed from the supply conveyor on the upper surface of the sorting conveyor. Since a pair of corresponding partition plates are provided on the left and right sides of the transfer path, the objects to be sorted can be reliably positioned on the transfer path of the sorting holes.

Therefore, the objects to be sorted do not accidentally enter the transfer path of the adjacent sorting hole, and the objects that are about to be transferred do not fit into the sorting holes and remain on the uppermost receiving plate constituting the stack. Selected fruits can be scraped off by scraping boards hanging between the partition plates and quickly fit into the sorting holes.
Accurate sorting work can be performed efficiently.
