Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorting device that accurately measures even a tilted object by retractably arranging mark sensors each having a distance gauge.

As shown in FIG. 1, an object to be measured, such as a construction panel P, carried in from a conveyor a in the previous process is identified by an identification device 1a equipped with a mark sensor C that identifies a black mark b on the side surface of the panel P, And while rotating in the left and right horizontal planes, the conveyor d on the upper surface transports the 11th, 2nd and 3rd yards e.
* In the sorting/discharging device 2a for discharging to fsg, as shown in FIG. When the object to be measured, for example, a construction panel P, comes into contact with the abutting plate at an angle, the mark b deviates from the discernable range of the mark sensor fc, making it impossible to identify it, or causing it to be carried out to the wrong yard due to malfunction. There was a problem.

The present invention aims to provide a sorting device that can solve these problems, and one embodiment thereof will be described below with reference to the drawings.

In Figs. 3 to 5, the sorting device 1 of the present invention has a conveyor a using driving rollers on the upper surface, and a plate serving in front of the sorting and sending device 2 that rotates left and right in a horizontal plane. It is placed behind the.

The sorting device 1 has a substrate 5 connected to the rod 4 of the cylinder 3, which is covered with a net at right angles to the side surface of the sorting and sending device 20, below the frame j. A guide shaft 6 protruding from the base plate 5 can be moved back and forth, and sliding shafts 1, 1 of the same length are freely pushed near both left and right ends of the base plate 5 and are appropriately prevented from rotating.

The forward position of the sliding shaft 7 is regulated by a collar 8 at the rear end, and a sensor receiver 10 having a horizontal sensor mounting plate 9 and an L-shaped distance gauge 11 are mounted at the tip of the sliding shaft 7.
and a compression spring 12 is disposed between the sensor receiver 10 and the substrate 5.

Therefore, the sensor receiver 10 is pressed forward by the compression spring 12 and can be retracted by compressing the spring 12.

In addition, for example, a photocoupler is used for the sensor mounting plate 9.
A mark sensor C that identifies the presence or absence of a black mark on the side surface of the object to be measured is installed facing forward, and the distance between the sensor C and the tip of the distance gauge 11 is determined by the photocoupler that is the mark sensor C. Set to the optimum measurement distance.

However, even when the construction panel P is conveyed in an inclined manner, the device 1 of the present invention advances the substrate 5 by reducing the cylinder 3 and moves the distance gauge 11 to the mark b on the side of the object to be measured.
The mark sensor C that is in contact with the side surface located in front can be moved forward while regressing until both come into contact with each other. Therefore, each mark sensor C can identify the presence or absence of a mark at a predetermined optimal position, preventing malfunctions. The mark b is detected correctly without any trouble, and the frame j rotates to reach the specified yard es.
Select and carry the object to be measured into the fsg.

As mentioned above, the device of the present invention is equipped with a distance gauge and is capable of retracting for each mark sensor, so even when the object to be measured is tilted, each sensor always measures the object at the correct measurement distance. can be identified, thus reducing malfunctions.

As the mark sensor, a reflective photoelectric sensor such as a photocoupler can be suitably used, and an arbitrary number of mark sensors can be attached to the substrate.
