Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a sorting device that sorts a plurality of inspected objects based on inspection results.

B. Prior Art For example, in a conventional continuous inspection device using X-ray television, when inspecting objects one by one, pass/fail is determined from the image on the monitor showing the inspection results. If multiple items were to be inspected at once, defective items were grabbed one by one using a gripping device such as a robot and sorted.

C. Problems that the invention aims to solve The former sorting device had the drawback of being inefficient because it could only inspect one item at a time. Also,
The latter sorting device uses a robot, which is expensive, and the sorting speed cannot be very fast, and it cannot handle cases where defective products are continuously transported.

Furthermore, in the conventional sorting device, the objects to be inspected are dropped onto a pallet or the like, which is not suitable for objects that are susceptible to impact, such as oxygen sensors for automobiles. Furthermore, in those with lead wires, etc., there is a risk that the leads may become tangled and cannot be reliably sorted.

D. Means for Solving the Problems The present invention uses a sorting device that sorts multiple inspected objects transported by a transport device after the inspection is completed according to the test results. A reversible device that is capable of integrally reversing a receiving section that receives an object to be inspected, a plurality of sorting mechanisms provided opposite to the receiving section, and the receiving section and sorting mechanism between a receiving position and a sorting position. and a device;
The present invention is characterized in that the inspection object received by the receiving section at the receiving position is transferred to a sorting mechanism at the sorting position and sorted according to the inspection results.

E Function When the inspected object reaches the receiving section after the inspection is completed, the reversing device reverses the receiving section and the sorting mechanism. As a result, the objects to be inspected are transferred to the sorting mechanism and sorted according to the inspection results.

F Embodiment FIGS. 1a and 1b show an X-ray inspection and sorting device using an embodiment of the sorting device of the present invention, in which a circulating conveyance path is constituted by roller conveyors 1a, 1c and belt conveyors 1b, 1d. , an X-ray inspection device 3 is provided in the transport path. In other words, the roller conveyors 1a and 1c are arranged such that the portions overlapping with the belt conveyors 1b and 1d are raised and lowered so that a pallet 31, which will be described later, can be placed thereon.
The X-ray inspection device 3 has an X-ray tube device 3a, an X-ray television camera (not shown), and a monitor camera 3b, and performs a fluoroscopic inspection of the conveyed object to be inspected and displays the image on the monitor television 3b. It is configured.

A sorting device 100 according to the present invention is connected to the belt conveyor 1d, and a good product discharge conveyor 5 and a defective product discharge conveyor 7 are connected to the sorting device 100. Further, an operation panel 9 is provided along the roller conveyor 1a, and by operating the operation buttons on the operation panel 9, the sorting conveyor 5 of the sorting device 100, which will be described later,
3a to 53c can be used to sort out non-defective products and defective products.

With reference to FIGS. 2 and 3, the sorting device 10

is installed. A chain 25 is wound between the sprocket 19 and the sprocket 23 which is supported by a bearing 21.
A cylinder 29 is attached to the arm 27 provided integrally with 3a.
is connected. By expanding and contracting the cylinder 29, as shown in FIG.
is rotated together with the shaft 13 between two positions, a receiving position P1 and a distribution position P2. Each of these members constitutes a reversing device.

Referring to FIG. 3, the base 15 has a shaft mounting portion 1.
5a, two arms 15b constituting a receiving part protruding from the lower end thereof, and a seat plate 15c extending from the upper end of the mounting part 15a in the same direction as the two arms 15b. The interval is belt conveyor 1d
The width of the base 15 is slightly larger than the width of the receiving position P.
1, the belt conveyor 1 is placed between the arms 15b.
d is located, and the two arms 15b can receive the pallet 31 (see FIG. 4) for conveying the inspection object conveyed by the belt conveyor 1d. The two arms 15b may be arranged inside the belt conveyor 1d.

A sorting mechanism 50 is attached to the seat plate 15c of the base 15, facing the arm 15b. Sorting mechanism 5
0 has three rows of belt conveyors 53a to 53c held by a holding part 51, and each of the belt conveyors 53a to 53c is independently driven and controlled by a motor device 55. In this embodiment, the objects to be inspected are conveyed and inspected while being accommodated in the pallet 31 shown in FIG. It is attached. Positioning pins (not shown) are provided on the base 15 so that the pallet 31 conveyed by the belt conveyor 1d properly faces the belt conveyors 53a to 53c at the receiving position P1.

A case will be described in which a plurality of objects to be inspected are inspected at once using the X-ray inspection and sorting apparatus configured as described above, and a plurality of good and defective objects are sorted out at the same time.

The three objects to be inspected housed in the pallet 31 are irradiated with X-rays within the X-ray inspection device 3, and the fluoroscopic image thereof is converted into electrical signals by the X-ray television camera and displayed on the monitor 3b. The inspector judges the quality of the inspected object based on the screen, and operates the buttons on the operation panel 9 according to the judgment result, and the judgment results are stored in a storage section (not shown) for each of the plurality of objects to be inspected.
is memorized. When the pallet 31 containing the object to be inspected reaches the arm 15b constituting the receiving section, the cylinder 29 retracts in response and the sprocket 23 rotates counterclockwise. This allows the sprocket 19 to be connected via the chain 25.
rotates counterclockwise and the base 15 moves to the receiving position P1.
It rotates from to distribution position P2. By this rotation of the base 15, each of the storage parts 31a to 3 of the pallet 31 is
The objects to be inspected stored in 1c are transferred to the sorting conveyor 5.
3a to 53c. At this time, since the pallet accommodating sections 31a to 31c and the sorting conveyors 53a to 53c are very close to each other, there is no fear that the objects to be inspected will collide and be damaged.

When the sorting mechanism 50 is reversed to the sorting position P2, the sorting conveyors 53a to 53c are driven in response. That is, according to the above-mentioned memory contents, the sorting conveyor corresponding to the inspection object of good quality is driven in the direction of the arrow OK in FIG. 1, and the sorting conveyor corresponding to the inspection object of defective quality is driven in the direction of the arrow NG. As a result, the objects to be inspected are distributed to the good product discharge conveyor 5 and the defective product discharge conveyor 7, respectively.

Further, in response to the completion of the sorting of the inspection objects by the sorting conveyors 53a to 53c, that is, in response to the sorting conveyor being driven for a predetermined period of time, the cylinder 29 is driven.
5 is reversed from the distribution position P2 to the receiving position P1 and waits for the next pallet 31 to be conveyed.

In the above embodiment, three objects to be inspected were housed in each pallet 31, but the number of objects to be inspected and distributed at one time is not limited to three.
The shape of the test piece 1 is not limited to the above-mentioned embodiment, and may be made to match the shape of the object to be inspected. Furthermore, the reversing device does not rely on a cylinder, chain, or sprocket; instead, a motor may be directly connected to the shaft 13, or a gear may be fixed to the shaft 13, and a drive gear that meshes with the gear may be driven by the motor.

Furthermore, the sorting device of the present invention can also be applied to other inspection devices, such as those using an industrial television to inspect the external shape, in place of the X-ray inspection device 3. Furthermore, the conveyor may be artificially driven in an appropriate direction after the objects to be inspected have been transferred to the sorting conveyor, without using a storage unit that stores the inspection results.

G. Effects of the invention Since the present invention is constructed as described above, it is possible to sort a plurality of objects to be inspected at once into good and defective items using a sorting device with a simple structure. Also,
Since the object to be inspected is transferred to the sorting mechanism by inverting it together with the sorting mechanism, there is no risk that the object to be inspected will be damaged.
