Description

[Detailed explanation of the invention] <Industrial application field> This invention combines the weights of articles stored in a plurality of article storage tanks in various ways, and calculates a predetermined target weight out of the total weight of each combination. The present invention relates to an article gathering device used to collect together articles discharged from article storage tanks in a combination weigher that selects a similar combination and discharges the articles from the article storage tanks constituting the selected combination.

<Prior Art> Conventionally, the above-mentioned article gathering device has a funnel shape (Japanese Utility Model Publication No. 17827/1983). In this article collecting device, a plurality of weighing hoppers are arranged along the edge of the upper opening, and articles are discharged into the collecting device from a selected weighing hopper. Each discharged article slides along the inner slope of the collection device, heads toward a lower discharge port, and is supplied via this lower discharge port to a packaging machine disposed below the collection device.

In addition, the collection device has two funnel-shaped objects as described above arranged concentrically, and the outlet of the inner funnel-shaped object penetrates the wall surface of the outer funnel-shaped object and protrudes outward. Yes (Japanese Unexamined Patent Publication No. 125322/1983).

In this collecting device, a plurality of weighing hoppers are arranged at the boundary between the inner funnel-shaped part and the outer funnel-shaped part,
The weighing hopper containing the selected article first discharges the article into, for example, an outer funnel, and then the article is then discharged from the weighing hopper containing the selected article into, for example, an inner funnel. The discharge is repeated and the articles are fed to packaging machines provided below the outer and inner funnels, respectively.

<Problems to be solved by the invention> However, in both of the above-mentioned collection devices, the discharged articles slide along a relatively wide funnel-shaped inner surface, so it is difficult to accommodate multiple articles in one weighing hopper. If there are many articles, there is a problem that the flow of articles tends to disperse and scatter. Furthermore, although the latter collecting device can feed articles to two packaging machines, the article discharge path is often a curved line, so the articles fall while changing their course, causing them to jump or swirl. Another problem is that the time it takes for the articles to reach the outlet varies.
These problems become particularly noticeable when the article is a granular product such as soybean.

This idea, as disclosed in Japanese Unexamined Patent Publication No. 57-125322, is based on the idea that when collecting articles, especially granular materials, discharged from a combination weigher at two different locations within the circumference of an article storage tank, the granular materials are placed at each collecting position. To provide an article collecting device in which articles are collected at almost the same time.

<Means for Solving the Problems> In order to solve the above problems, the present invention combines various weights of granules in a plurality of article storage tanks arranged on an arbitrary circumference, and A combination whose total value is equal to or close to the target value is selected from among the combinations, and the selected combination is a combination that can discharge the particulate matter from the article storage tank to the inside and outside of the circumference. In the scale, a plurality of receiving hoppers are arranged below each two adjacent article storage tanks, and each of these receiving hoppers collects the granules discharged by the article storage tanks inwardly of the circumference. It is divided into an inner chamber for receiving objects and an outer chamber for receiving granular objects discharged outwardly from the circumference of the article storage tank, and each of the inner chamber and the outer chamber has a discharge port at a lower end, First and second particulate matter gathering positions are provided at different positions inside the circumference below each of the receiving hoppers, and each of the first and second particulate collection positions is provided at one discharge port of the outer chamber and the inner chamber of each of the receiving hoppers. One end of the first cylindrical body is connected, and the other end of each of the first cylindrical bodies is extended in a non-swiveled state to a first particulate collection position, and the outer chamber and the inner chamber of each receiving hopper are One end of each second cylindrical body is connected to the other outlet of the second cylindrical body, and the other end of each second cylindrical body is extended in a non-swiveled state to a second particulate collection position. It is.

<Function> According to the present invention, for example, the granular material introduced from the article storage tank into one of the outer chamber and the inner chamber of each receiving hopper passes through each first cylindrical body, and is then transferred to the first granular material. It is supplied to the object gathering position in a non-swiveled state. Also,
The granules input from the article storage tank into the other of the outer chamber and the inner chamber of each receiving hopper pass through the second cylindrical body in a non-rotating state and are supplied to the second granule collection position. Ru. That is, according to the present invention, granules can be collected at two granule collection positions provided inside an arbitrary circumference without using a conventional funnel-shaped collection chute.

<Embodiment> This embodiment has seven receiving hoppers 1 to 7 as shown in FIG. These receiving hoppers 1 to 7 are arranged along a certain circumference.
The interiors of these receiving hoppers 1 to 7 are divided into two inner chambers 1a and 1a by partition walls 10 and 12, respectively.
It is divided into 1b to 7a, 7b and outer chambers 1c, 1d to 7c, 7d. inner room 1
a, 1b to 7a to 7b each have one outlet 14a to 14g at the bottom. Further, the outer chambers 1c, 1d to 7c, 7d each have one outlet 16a to 16g at the bottom.

A total of 14 auxiliary hoppers 13a to 13n are provided on both sides of the partition wall 12 of each partition wall 10 of each receiving hopper 1 to 7, as shown by dotted lines in FIG. These auxiliary hoppers 13a to 13n
is configured such that the articles inside can be discharged to any of the inner chambers 1a, 1b to 7a, 7b and the outer chambers 1c, 1d to 7c, 7d.
This auxiliary hopper includes one with two discharge gates corresponding to the inner and outer rooms,
Although it has only one discharge gate, it is possible to use one configured so that it can be tilted toward the inner and outer chambers. A weighing hopper equipped with weighing means is provided above these auxiliary hoppers.

Two discharge hoppers 18 and 20 are arranged at the inner lower part of the receiving hoppers 1 to 7. Each of these discharge hoppers 18, 20 has an article supply port in its upper portion and a discharge port closed by gates 22, 24 in its lower portion. A packaging machine (not shown) is provided below each of these discharge ports.

Inner discharge ports 14a to 1 of receiving hoppers 1 to 7
One ends of pipe-shaped chute 26a to 26g are connected to 4g. In addition, pipe-shaped chute 28a to 28g are provided at the outer discharge ports 16a to 16g.
are joined at one end. Pipe-shaped chute 26
The other ends of the pipe-like chute 26f extend above the inlet of the discharge hopper 20, and the other end of the pipe-like chute 26f extends over the discharge hopper 18.
It extends over the inlet. Similarly, pipe-shaped chute 28a, 28b, 28c, 28d, 28
The other end of the pipe-like chute 28f extends over the input port of the discharge hopper 20.
The reason why only the ejection hoppers of the pipe-shaped chute 26f and 28f, whose other ends extend, are replaced is to prevent the pipes from interfering with each other due to the structure of the pipes.

Such an article gathering device operates as follows, for example. It is now assumed that each of the auxiliary hoppers 13a to 13n contains a weighed article, for example, a granular material such as soybean, and each weighed value is input to a control device (not shown). In this state,
The control device sequentially combines the measured values according to (2 ¹⁴ -1) combinations, and selects from each combination the one whose total weight is equal to or closest to the predetermined weight. The auxiliary hoppers constituting this selected combination are, for example, 13a, 13f, 13g, 13l.
If so, the control device will control the auxiliary hopper 13.
Remove the particulate matter in a, 13f, 13g, and 13l to room 1.
b, 3a, 4b, 6c. The discharged particulate matter is pipe-shaped chute 26a, 26c, 26
It is supplied to the discharge hopper 20 through ports d and 28f. When the discharge hopper 20 receives an article acceptance signal from the packaging machine, the discharge hopper 20 transfers the supplied granules to the gate 2.
4 and feed it to the packaging machine.

The control device includes auxiliary hoppers 13a, 13f, 13
When the auxiliary hoppers 13a, 13f, 13g, and 13l are emptied, granules are immediately supplied from the upper weighing hoppers, and the weighed values are input to the control device and the combination is performed again. resume. In addition, granules are newly supplied to the empty weighing hopper and weighed. By the resumed combination, for example, the auxiliary hopper 13d,1
Assume that 3e, 13h, and 13k are selected. The control device includes auxiliary hoppers 13d, 13e, 13h, 1
3k of granules are discharged into rooms 2c, 3d, 4c, and 6b. The discharged particulate matter is transferred to pipe-shaped chute 2.
It is supplied to the discharge hopper 18 through 8b, 28c, 28d, and 26f. When the discharge hopper 18 receives an article acceptance signal from the packaging machine, it opens the gate 22 and supplies the supplied granules to the packaging machine.
Thereafter, the above-described operation is repeated.

In the above embodiment, one hopper is used for two auxiliary hoppers.
The receiving hopper was divided into two inner rooms and two outer rooms, a total of four rooms.One receiving hopper was provided for each auxiliary hopper, and this receiving hopper was divided into one It may be divided into two rooms: two inner rooms and one outer room. Alternatively, the auxiliary hoppers may be removed and weighing hoppers capable of discharging articles into either the interior or exterior chambers may be provided at these locations. Furthermore, discharge hopper 1
8 and 20, but these are for waiting until the packaging machine is ready to pack the discharged granules, and the packaging machine can wrap the granules instantly at high speed. It is unnecessary when there is no need to do so.

<Effects> Conventionally, when supplying articles from a plurality of article storage tanks located on the circumference to two locations within the circumference,
Two funnel-shaped collecting chutes are arranged concentrically inside and outside, and the discharge ports of these inner and outer collecting chutes are
They must be oriented to the two gathering positions mentioned above, and when granular materials are used as articles, the inner and outer gathering chutes must intersect at some point, so the article is made up of these inner and outer gathering chutes. Since the path through which particles travel is often composed of curves, particles fall while changing their course many times. Therefore, since the particulates jump or swirl, the time it takes for the particulates to reach the collection point becomes uneven.

However, in the article gathering device according to this invention, the granules put into the inner and outer chambers of the receiving hopper are transferred to the first and second articles through the first or second cylindrical body provided in a non-rotating state. Since the particles are collected at the gathering position, even though the particles are collected at two locations on the circumference, the particles do not rotate greatly within the first and second cylindrical bodies, and the particles are Particulate matter that is well organized and should be collected, for example, at the first collection position, is collected at the first collection position at approximately the same time. The same applies to the second gathering position. Therefore, each time a combination is discharged, the time interval between what was discharged last time and what was discharged this time becomes clear, so the time interval between discharges of the combination scale can be shortened. That is, since the discharge time interval of the combination weigher can be shortened, the throughput is greatly improved.

Further, according to the present invention, since two article storage tanks are provided for one receiving hopper, even if one article storage tank is provided for one receiving hopper, the first and second article storage tanks are Since the number of the second cylindrical bodies can be reduced, the configuration can be simplified.
