Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates generally to weight sorting devices, and more particularly to fffffi sorting devices, such as those for weight sorting fruits such as tangerines.

This type of weight sorting device is associated with a cup conveyance line that sequentially conveys cups for placing fruits, as typified by a fruit sorting machine that sorts fruits by weight. A rice placing section, a weighing section for measuring the weight of the fruit placed in the cup, and a cup that faces the cup+117 conveyance line and is provided on one or both sides of the conveyance line in the conveying direction are overturned and the fruits placed thereon are swept away. It has a plurality of classifying devices arranged sequentially in the cup conveying direction, and the fruit placed in the cup is classified according to its weight.
ff is determined by the number of pulses proportional to the amount of movement of the conveyance chain on the cup conveyance line, and the fruit is sorted by driving the sorting device. When dispensing to the dispensing section, since the cup support means is rotatably locked to the transfer means on the dispensing section side, the cup is conveyed at a radius equal to the extension of the support means around this locking point. Rotate 1' in a large arc on the upper side of the surface.

Therefore, when the cup falls over, it goes far beyond the upper edge of the cup when it is not tipped over, and the drop between the cup and the dispensing section becomes considerably large. Therefore, there is a problem in that the objects to be sorted, such as fruits, suffer from the impact caused when they fall, causing scratches and the like, resulting in a decrease in commercial value.

Therefore, the present invention is intended to improve the above-mentioned problems of the prior art.The purpose of the present invention is to rotate and overturn the cup to the extent that the upper edge of the saw blade is used downward when not overturning when dispensing objects to be sorted such as fruits. The object of the present invention is to provide a weight sorting device that minimizes the impact applied to objects to be sorted, such as fruits.

The features of the present invention for achieving the above object include a cup 1 on which an object to be sorted is placed, a transfer means 2 for transferring the cup 1, and a transfer means 2 for transferring the cup 1 with an object to be sorted thereon. The cup 1 is configured to support the object so that it can be weighed and to discharge the object to be sorted by releasing the support in the classification section according to the weighed amount.
In the weight sorting apparatus, the support means 2 includes a left support means and a right support means that prevents the cup 1 from overturning so that substantially the entire body of the cup 1 falls from the upper edge of the cup 1. In a weight sorting device, such as one constituted by a support means.

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

FIG. 1 is a partial plan view of a weight sorting device according to an embodiment of the present invention, FIG. 2 is a partial sectional view, FIG. 3 is a partial sectional view of an embodiment of the present invention, and FIG. FIG. 3 is a diagram showing the relationship between a storage cup and a load cell.

Reference numeral 1 at 83 in FIGS. 1 to 4 is a cup on which fruits and the like are placed.

Next, reference number 7 is a load cell (pressure cahimsa) installed in a measuring section (not shown) for measuring the weight fDiTI of the crop placed in the cup and outputting an analog voltage signal corresponding to the weight to a control device (not shown); Reference numeral 8 denotes an arm rotatably locked to a support shaft 3 fixed to the transfer means 2 via a fulcrum 3a.

The arm 8 is rotatably engaged with the cup 1 via a long hole 8a provided in the arm 8 and a protrusion 1a provided in the cup 1. The support means 3, that is, the support shaft 3, is attached to and moves on the transfer means 2, that is, the traveling chain 2, which is provided on both sides in the conveyance direction of a conveyance line having a plurality of cups 1 for placing objects to be sorted. Accordingly, the arm 8 also slides on the retaining means 4, that is, the soil portion of the guide rail 4, which is provided on both sides of the 11123Z line in the conveying direction except for the section corresponding to the base section 81 (not shown).

Next, guide rails 4 are disposed intermittently on both sides of the conveyance line in the conveyance direction in accordance with the number of discharge ports of the classifying device.

Further, in this embodiment, a solenoid 4a for moving the guide rail up and down is installed directly below the guide rail at the outlet of each classifier. The drive of the solenoid 4a is controlled by a control device (not shown) based on measurement information that measures the weight of the cup-mounted fruit conveyed to a weighing section (not shown) using a load cell 7 and outputs the measurement result as an analog voltage signal. It is configured so that In this embodiment, one solenoid 4a is provided at the center of the discharging port of each classifier, but the same result can be obtained even if one solenoid 4a is provided at each end of the dispensing port of each classifier. Of course, it is effective. In addition, in this embodiment, the sorting section is provided with a sorting device discharging section facing both sides of the cup conveying line in the conveying direction. Although it has a 4R configuration, it is of course possible to change it depending on the application, or to install the classification section on one side in the conveyance direction.

The operation of the above configuration will be explained below.

When the operator turns on the start switch (not shown) of the grade sorting device, the drive means 2 starts driving, and as a result, the conveyor and the sorted object placement cup 1 on which the fruits to be sorted are placed are integrated. When the fruit to be sorted reaches the weighing section (not shown), the fruit is placed on the measuring surface of the load cell 7 by the support means 3 as shown in FIG. The weight of the fruit to be sorted is measured while it is placed on the rotatably supported placing cup 1.The load cell 7 immediately responds to the measurement weight after measuring the weight of the fruit. It outputs an analog signal and gives it to a control device (not shown).The control device (not shown) takes in the signal, calls the pre-stored heavy weight class sorting data, compares it, and then determines the weight class of the fruit. and gives a drive command signal to a predetermined classifier.The drive command signal output from the control device (not shown) is given to a solenoid 7Ia provided in the classifier for a predetermined unit quantity.On the other hand, the load cell 7 The fruit to be sorted, whose weight M has been measured by a When the cup 1 is transported to the classification device of the weight class corresponding to the measured weight, the solenoid 4a is activated and moves down the guide rail 4 that was supporting the transport object until then, so that the cup 1 is changed to the cup 1 when it is not overturned. The fruits to be sorted in the cup 1 will be tipped down so as to fall from the upper edge and will be discharged to a predetermined sorting device l\.Note that, as in this embodiment, the dispensing part of the sorting device is in the conveying direction of the conveying line. For example, if the sorting devices installed on both sides and used for the dispensing are placed on the right side in the conveyance direction, the next fruit to be sorted happens to be the same as the previous fruit. If they belong to the same weight class, the control device (not shown) sends a drive command signal to the left classification device that is not used for dispensing, and drives the solenoid 4a of that classification device. The solenoid 4a is actuated based on the drive command given from the controller (not shown), and moves the guide rail 4 on the left side in the conveyance direction, which has supported the arm 8 up to now, downward, thereby overturning the cup 1 for placing the objects to be sorted. The fruit will be taken out.

As explained above, according to the present invention, for example, a drawer conveyor is provided on one side or both sides in the conveyance direction of the conveyance line that holds the cup for placing the sorted articles moving at high speed, for pulling out the sorted articles. Unlike the prior art, when a cup falls over, almost the entire cup falls below the upper edge of the cup when it is not overturned. It is possible to do very little. Therefore, when discharging the objects to be sorted, the impact applied when they fall is reduced, making it difficult for scratches to occur, and the efficiency of discharging the objects to be sorted is also improved due to the reduced head. Qin.
