[0015]
When the solenoid 2 is energized, the gate 5 connected to the solenoid rotates in the opening direction (FIG. 7), and the gate 5 guides the object to be sorted 31 discharged from the outlet of the hopper 24 to the slide 29. Functions as a guide member. In the example of FIG. 7, the gate 5 on the right side is in an open state, but whether to energize the two right and left solenoids 2 depends on the weight signal of the object to be sorted 31 measured by the load cell 21. Is determined and determined.
[0016]
In this apparatus, (1) the right gate 5 is opened. (2) Open the gate 5 on the left side. (3) Close both gates 5. The following three operations can be selected.
In the case of (1), the object to be sorted 31 into which the hopper 24 is put is discharged to the right slide 29, and in the case of (2), it is discharged to the left slide 29. In the case of (3), it passes through the main body 15 downward and is discharged from the lower end of the main body 15.
Thus, in this apparatus, the object to be sorted 31 can be sorted in three stages according to its weight. In order to distinguish the first gate device 50 that can be selected in three stages from the second device that can be selected in the following four stages, it is hereinafter referred to as a gate device 50A.
[0017]
In the second example shown in FIGS. 10 and 11, the gate 5 is attached to the main body portion 15 of the sorting gate device 50 on three surfaces excluding the rear side. Each gate 5 is provided with an opening / closing mechanism similar to the above example, and the operation of each opening / closing mechanism is performed by a computer according to the weight signal of the object to be sorted 31 measured by the load cell 21.
Therefore, in the second gate device 50, the object to be sorted 31 can be sorted in four stages according to its weight. In order to distinguish the second gate device 50 that can be selected in four stages from the first device that can be selected in three stages, it is hereinafter referred to as a gate device 50B.
[0018]
The apparatus of FIG. 1 is configured by connecting a gate device 50B on the upper stage and a gate apparatus 50A on the lower stage. In FIG. 1, a part of the slide 29 is omitted.
In this device, a three-stage sorting in which the object to be sorted 31 is discharged to the left and right and front slides 29 by the gate device 50B and a sorting to fall to the lower gate device 50A are performed. In the gate device 50A, the left and right slides are arranged. A total of three stages of sorting, that is, the two-stage sorting discharged to 29 and the sorting discharged from the lower end opening are performed.
Therefore, according to the apparatus shown in FIG. 1, a total of six stages of sorting are performed. Reference numeral 30 denotes a reservoir box.
[0019]
11 and 12 is configured by connecting gate devices 50A and 50B in two upper and lower stages. In FIG. 12, a part of the slide 29 is omitted. In this apparatus, the sorting target 31 is subjected to three-stage sorting in which the upper gate device 50B is discharged to the left and right and front slides 29, and sorting to drop to the lower gate device 50B. In 50B, a total of four stages of sorting, that is, three-stage sorting discharged to the left and right and front slides 29 and sorting discharged from the lower end opening, is performed.
Therefore, according to the apparatus shown in FIGS. 11 and 12, a total of seven stages of sorting are performed. Reference numeral 16 in FIG. 13 denotes a connection fitting for connecting the upper and lower gate devices 50. By attaching the connection fitting 16 to the plate 15a of the gate device 50 with bolts 16a, a plurality of gate devices 50 are moved in the vertical direction. Easy connection. Therefore, an appropriate gate device 50 can be selected on site according to the specification and can be easily assembled.
[0020]
In the apparatus of FIGS. 1 and 2 and the apparatus of FIGS. 11 and 12, two gate devices 50 are stacked in the vertical direction, and a slide 29 for taking out a plurality of objects to be sorted 31 is also arranged in the vertical direction. Since it is installed, that is, the apparatus is three-dimensional, it is possible to minimize the installation space for the weight sorting apparatus even though the sorting can be performed in six stages or seven stages.
2 and 12 are configured by stacking two gate devices 50 in the vertical direction, but it is also possible to configure by stacking three or more gate devices 50 in the vertical direction. Needless to say. In this case, it goes without saying that which gate device 50 is selected can be set according to the user's request.
[0021]
In the above apparatus, each solenoid is actuated by computer control. That is, when the object to be sorted 31 is put into the hopper 24, its weight is measured by the load cell 21, and the measured value is sent to the computer and stored. At this time, the door 26 is in a closed state. Based on the stored weight, the computer determines which final gate 5 is to be opened, and the solenoid 2 of the specified gate 5 is energized. That is, after the discharge slide 29 of the object to be sorted 31 is determined, the solenoid 19 is energized and the door 26 is opened.
[0022]
When the sorting process of the first object to be sorted 31 is completed, the energization to the solenoid 19 is cut off, and the energization to the solenoid 2 is also cut off at the same time, so that the door 26 and the gate 5 are restored to the original state. By repeating this operation, it is possible to perform the weight selection of the objects to be selected 31 continuously.
[0023]
【The invention's effect】
As described above, according to the present invention, the following effects can be obtained.
(1) Since the apparatus is three-dimensionalized, it is possible to extremely minimize the installation space for the weight selection apparatus, although it is possible to perform selection in multiple stages (for example, 6 stages or 7 stages). .
(2) Since it is possible to simply configure the weight selection device by stacking a plurality of gate devices in the vertical direction at the site, it is possible to easily meet the user's request.
