Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in cup holding means, and more particularly to a method and apparatus for holding cups (saucers) used for transporting articles in gravimetric classification equipment.

In such a gravimetric classification device used for classifying fruits, generally ? It is considered imperative to accurately measure the fruit in the cup.

Some of these devices include a number of cups forming rows, with a number of such rows forming an endless loop. The cups of each row are generally interconnected by cross rods, the free ends of said rods being connected to respective drive chains so that the cups are moved between the various locations receiving the plant weight of fruit.

This has a serious drawback: the fruits are irregularly shaped (
This is especially true in situations where the fruit is not centered in the cup (e.g. pair-shaped) or the fruit is not centered in the cup. In both of the above cases, at least a portion of the weight of the fruit is received by the cross rod and therefore by the drive chain and its holding device, and the weight of the detected stolen goods and cup is therefore as much as it deviates (see above, the cross rod (by the amount received by).

An object of the present invention is to provide a method and device for holding cups in a pre-classifier, which prevent the contents from being irregularly shaped or placed off-center in the cup. To facilitate accurate measurement of the total weight of a cup and its contents even when Another object of the invention is to
The object of the present invention is to eliminate certain other disadvantages inherent in conventional gravimetric classification devices.

The present invention provides a method for holding cups in a one-tray sorting device having a number of cups into which articles to be weighed are placed, the method comprising: connecting the cups to a transfer means; , comprising rocking means for enabling said cup to rock on or relative to said coupling means.

The present invention further provides a cup holding device for use in a gravimetric classification device having a number of cups into which the articles to be counted are placed, the structure comprising a connection for connecting said cups to a transfer means. and rocking means for enabling said cup to rock on or relative to said coupling means.

The present invention will be explained below with reference to embodiments shown in the drawings.

FIG. 1 shows a holding device according to the prior art, in which a number of cups in each row l are connected to rods 2
The free end of the rod 2 is connected to a drive chain so that the cup l is fed in the direction indicated by arrow A between the various locations of the weight classifier.

At some point in the gravimetric classifier it becomes necessary to weigh the cup 1 and its contents (not shown). As mentioned above, if the contents of the cup are irregularly shaped or if the contents are not centered #C of the cup 1, at least part of the weight of the Tsuburaya proboscis will be due to the rod 2 and therefore There is less mucus that is received by the chain 3 and the chain retaining structure and therefore detected by a detector such as a load cell.

In the present invention, this drawback is overcome and it is possible to carry out accurate weighing of the samurai cup and its contents.

In the present invention, as shown in FIGS. 2 and 4,
The cup 4 is pivotally mounted on a set of retaining arms 5 (only one of which is shown) by a pivot pin 6 received in a hole 7 in a side wall 8 thereof, and the other retaining arm 5 is swingably mounted on the other side wall 8.

The arm 5 has a washer-like body 9 which can be magnetized.
, and the washer-like body 9 is disclosed in U.S. Patent No. 404,331/82 (this is a Japanese
A13299871982).

The arm 5 has at its front end a hole 10 for receiving a rod 2, which passes through the hole IO and is connected to the chain 3. A sufficiently oversized hole 12 is made in both walls of the front end l of the cup 4, and the rod 2 is inserted into this hole.
2 and can move vertically in this hole so as not to touch the cup 4 when the arm 5 is on the force detector.

In this way, the cup 4 can freely float or rock around the point of attachment to the storm 5. The dimensions of the aperture 12 are such that the front end 11 of the cup does not touch the rod 2 during use, thus preventing the weight of the cup 4 and its contents from being received by the rod 2.

The bottom end of the arm 5 may rest on the sensing body of the weight detector during a weighing operation in which the weight of the cup 4 and its contents is ascertained. The maximum deformation of the detector lid is such that no contact can occur between it and the rod 2. Thus, regardless of whether the contents are irregularly shaped or irregularly placed in the cup 4, any portion of the amount M of the cup 4 or its contents 9 will be removed by the rod 2. It will never be received.

On the other side, shown in FIG. 3, the chain 3 is connected to a rod 2 passing through a hole 14 made in the bracket 15. The two free ends of the brackets 1-15 are each provided with a pin 16 on which a front end 17 of a cup 18 can be held swingably, the pin 16 being provided with a suitable bolt made on each side of said front end. extending into an aperture of appropriate dimensions. cup 18
In the illustration, the washer-like body 9 shown in FIG. 2 is placed on the L-shaped body 6. The pivot point along the sidewall of cup 18 is shown as pivot pivot 716.

Openings 19 are made on both sides of the rear end of the cup 18, so that the cup 18 is symmetrical about its central axis.
8 is attached to each bracket 15 from either end thereof.
can be connected to The provision of the opening allows the cup 18 to be used in the embodiments shown in FIGS. 2 and 4.

In use, even if the contents in the cup 18 are irregularly shaped or irregularly placed, one end 13 of the cup is horizontally positioned opposite the weight detector. It can be kept. This is accomplished by the cup 18 rocking about the pin 16 as it moves over the detector in the direction of arrow A, and the weight of the cup or contents No portion is received by rod 2.

As explained above, the present invention provides a weighing cup for a gravimetric classification device, the structure of which enables effective and transparent weighing of the cup and its contents. .
