Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyor device with a saucer for a sorting machine that sorts various spherical agricultural products.

Various types of shape sorters or weight sorters with saucers are in widespread use, but these known shape sorters are conveyor devices with saucers that have a structure that makes it impossible to measure weight. The one for the weight sorter is a tray-equipped conveyor device having a weighing link mechanism, and each tray-equipped conveyor device has its own shape and structure.

In conventional sorting machines, the trays are all plate-shaped or bowl-shaped, as shown in FIG. 1A and B, with a space formed at the lower side. Therefore, when the number of articles discharged from each sorting/discharging section increases on the tray, they accumulate on the sides of the travel path of the tray. If the accumulated items protrude to the lower side of the tray, they will not only be damaged as shown in Figure 2, but the next tray will not be able to tilt, resulting in poor sorting, and the tray and reception attachment mechanism (weighing link mechanism) will be damaged. It had a defect that caused it to break.

The object of the present invention is to eliminate the above-mentioned drawbacks and to provide a novel conveyor device with a tray that can be used in both a shape sorter and a weight sorter.

In order to achieve the above object, the present invention forms a skirt-like side wall on the inclined side of the tray from the upper periphery to the lateral lower part to prevent articles from entering the lateral lower part of the tray. The mounting portion of the saucer is configured so that the saucer portion can be raised from the saucer support member attached to the conveyor chain, so that the weight can be measured.

That is, a saucer mounting member, which is pivotally supported so as to be tiltable laterally, is held horizontally by an engagement mechanism on the upper part of the main body attached to the conveyor chain, and the saucer is loosely fitted in the upper part of the saucer mounting part vertically, left and right, and front and rear. The lower part of the tray has a sliding surface that is horizontal in the direction of travel, and when the sliding surface is supported by a receiving rail, the tray will float above the mounting part. When the engagement of the tray is released, the tray tilts to the side and the article is discharged.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Diagrams showing one embodiment of the present invention will be described below.

1 is a conveyor device with a tray for the sorting machine, 2 is a conveyor chain, 3 is a tray device for carrying sorted items one by one, 4 is an electronic weighing device for measuring weight, and 5 is an imaging device for measuring shape. , 6 is a computing device, 7 is a pedestal or receiving box, and 8 is an article.

The saucer device 3 includes a main body 9, a saucer mounting member 10,
The main members of the engagement mechanism 11 and the saucer 12 are constructed as follows.

The main body 9 is attached to the conveyor chain 2 with a mounting pin 13 so as to run horizontally, and has a tilting fulcrum 14 at the top.
is provided, and the saucer mounting member 10 is mounted with a fulcrum pin 15 so as to be tiltable laterally.

The saucer mounting member 10 has an engaging portion 17 at a position corresponding to the engaging piece 16 provided on a part of the main body 9 to form an engaging mechanism 11, and normally runs while being held horizontally.

The lower part of the saucer 12 is provided with a sliding part 18 for running on the weighing device 4, and the saucer mounting member 10
It is installed loosely so that it can freely move (float) up and down, left and right, and front and back without being fixed to the surface. When the sliding part 18 is on the weighing device 4, the saucer 1
2 is slightly lifted up, and gaps 20 are created between the saucer 12 and the saucer mounting member 10 in the upper and lower, right and left, and front and rear directions at the loose fitting mounting portion 19, resulting in a non-contact state. On the other hand, a part of the saucer mounting member 10 has a pushing member 22 that pushes a vertical surface 21 provided on a part of the saucer 12 in the traveling direction to maintain the gap 20 in the front-rear direction.
has been established.

The tray 12 forms a side wall 12b that bulges from the upper periphery 12a of the article storage section toward the lower side at a curve with a radius R from the tilting support 14.
The running side surface of the tray 12 is configured to be the same wall surface both when it is horizontal and when it is tilted.

Reference numeral 23 denotes a tilting spring, which is attached to the tilting fulcrum part by being hooked around the fulcrum pin 15 to the upper part of the main body 9 and the saucer mounting member 10, and has no effect of tilting the saucer 12 laterally when the engagement mechanism 11 is released. ing.

24 is a tilting guide pin, and 25 is a tilting guide, which can be omitted if the saucer 12 is to be suddenly tilted and discharged; however, in general, if fruits are suddenly tilted and discharged, the product will be damaged, so the engagement mechanism 1 is omitted.
Even if the conveyor chain 1 is released, the tilting guide 25 controls the tilting guide pin 24 attached to the tray 12, so that the conveyor chain gradually tilts as it advances.

26 is a restoration guide for the tilted saucer 12;
The function is to restore the tilted receiving tray 12 to the horizontal state as it advances after discharging the articles. The restoring guide 26 is provided for each sorting point and restored at each position, and sometimes it is not restored at each sorting point.
There are cases where one place is provided at the end of the conveyor and the whole thing is restored.

Reference numeral 27 denotes a discharge actuation device which uses an actuating device such as a solenoid or a pneumatic hydraulic cylinder to contact the engagement piece 16 protruding from the main body 9 of the tray device 3 in the sorting section to release the engagement mechanism 11 and tilt the tray 12. This serves to discharge and sort the articles 8 onto the receiving box 7.

The discharge actuating device 27 is a weight measuring device 4 or an imaging device 5 for measuring the shape, similar to a conventionally known sorting machine.
A calculation device 6 calculates the measurement signal from the conveyor and compares it with a preset class classification value to detect the corresponding class, and it is activated by a sorting signal sent in synchronization with the conveyor.

As described above, the present invention forms a skirt-like side wall that bulges downward with a curve of radius R from the tilting fulcrum 14 on the side in the traveling direction of the tray 12, so that even when the tray runs horizontally, the side wall can be tilted. Even when this happens, the running side of the receiving tray becomes the same wall surface, so the items 8 accumulated on the receiving box 7 will not get stuck under the receiving tray 12 and be damaged, and since no obstacles will enter the lower part of the receiving tray, it will not be possible to eject the items. Safe and reliable sorting can be done without any problems.

In addition, the tray can be gently tilted as it progresses, and can be allowed to advance while tilted until the end of the conveyor, so a sorting conveyor device with a good working environment without noise caused by tilting and restoring the tray can be obtained. It will be done.

In addition, the saucer device of the present invention does not have a link mechanism that was required in the tray device of a conventional weight sorter, and has an extremely simple structure consisting of a tray, a tray mounting member, and a main body, resulting in a significant cost reduction. Moreover, it is possible to obtain a sorting conveyor device that is free from failures.
