Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an article combination device which selects an optimal combination by drawing four combinations of the weights or numbers of articles housed in a storage tank, and discharges articles from the storage tank according to the selected combination. In particular, the present invention relates to a device for collecting discharged articles.

Conventionally, as a device for collecting the above-mentioned items, one collection chute is provided below each storage tank, and the items discharged from the storage tank are thrown into the collection chute from the upper edge opening of the collection chute, and then Some of them were collected at the bottom of the ffi chute by falling, and the gates installed there were opened and dumped into containers, etc. However, in such a gathering device,
The distance from the upper opening to the gate is long; the objects are collected by sliding along the wall of the collection chute; the collection speed varies due to the different friction coefficients and air resistance of the objects; and even if the objects have not yet been discharged from the gate. Regardless, there were cases where the next combination was obtained and new items were thrown into the collection chute, causing old and new items to mix together. Therefore, it is necessary to control the items so that they are thrown into the collection chute after they are discharged from the collection chute, and there is a problem in that the number of times the items can be discharged from the collection chute per unit time is considerably limited. .

This invention solves the above problem, and therefore,
Divide the collecting chute into multiple sections, and separate each storage tank and collecting chute 1.
- A sorting device is provided between X and X, so that the articles discharged from the selected storage 42 are supplied to any section of the collection chute by the sorting device.

With this configuration, after the articles from the storage tank 411 related to a certain combination are supplied to one of the compartments, the articles from the storage tank related to the next selected combination can be supplied to another compartment. When you hit a group chute, you can increase the number of shots.

For example, the same effect can be obtained by dividing the collection chute into two sections and providing a discharge port that opens on both sides of the storage tank so that the goods can be discharged into one of these sections. Even if there is a possibility that some of the articles may be erroneously supplied to the other compartment, however, as in this invention, the articles are discharged from a storage tank that has only one υ1 output 1' 11. Sorting device? 9 is used to supply one of the compartments, there is no chance of accidentally supplying a part of the article to another compartment.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments. A first embodiment is shown in FIG. In the figure, 2 is a distributed feeder, around which a plurality of linear feeders 4 are arranged radially. The compound i! is subordinate to each of these 100-decimal feeders 4. The hoppers 6 between &, , r4-+ are arranged in a circle. Therefore, the articles to be weighed are supplied from the distributed feeder 2 to the intermediate hopper 6 via each linear feeder 4. Each of these intermediate hoppers 6 has only one discharge gate 8. 10 is an actuator for opening the discharge gate 8. Weighing hoppers 12 are arranged below each of these intermediate hoppers 6 in a circular manner, and by opening the discharge gates 1-8 of the intermediate hoppers 6, objects to be weighed can be removed from each intermediate hopper 6. is supplied. The metering hopper 12 also has only one extraction gate 14. 16 is an actuator for opening the discharge gate 14. The weighing hopper 12 weighs these articles to be weighed and supplies the weighing signal to the combination calculation section 18.

The combination calculation unit 18 combines various weighing signals, selects a combination equal to or closest to a predetermined weight, and activates the actuator 16 of the weighing hopper 12 according to the selected combination to discharge the discharge game 1-14. open.

A collecting chute 2o is arranged below each 31" quantity hopper 12. This collecting chute 1-20 includes a first section 20a shaped like a truncated cone and a first section 20a which is also shaped like a truncated cone. a second partition part 2ob which has a larger diameter than the first partition part 20b and is arranged outside the first partition part 20b.
As shown in FIG. 1, the sections 20a and 1201) partially intersect with each other, and discharge gates 1 to 22aX22b are provided at each lower end.

A sorting chute 24 is arranged in a circular manner between the collecting chute 20 and each weighing hopper 12. The distribution chute 24 has a container R+'i with both upper and lower ends open.
It is rotatably supported by riqlI2〒1
The actuator 226 connects the first partition 2Oa side and the first
It is rotated to the partition part gob side. Therefore, ＼Weighing hopper 1
The articles to be weighed in 2 are supplied to the first section 20a or the second section 2ob via the sorting chute 24. Therefore, the weighing hopper 12 associated with the combination obtained the first time supplies the weighing product to the first compartment 20a, and the weighing hopper 12 associated with the combination selected the second time supplies the weighing product to the second division 20a.
The article to be weighed is supplied to the compartment 20b, and thereafter the article to be weighed is alternately supplied to the first and second compartments 20a, 201). The first section 20a and the second section 20b
