Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an article inspection device for inspecting continuously supplied articles.

[Conventional technology]

As a so-called parts feeder that continuously supplies articles, a pole feeder that arranges articles while rotating is well known. Such a feeder is disclosed in, for example, Japanese Utility Model Application No. 57-53416.

[Problem that the invention seeks to solve]

By the way, when inspecting an article fed by such a feeder, there is a large vibration on the feeder, and when inspecting the details of the article, there is a possibility that the inspection may be erroneously recognized due to this vibration. In particular, optical sensors (e.g. TV
When inspecting an article using a camera, etc., measures against vibration are required. Also, according to the article, it is difficult to properly position it at the detection position with the detection device (<, which is a bottleneck in automation.

Furthermore, in conventional inspection, a series of steps are carried out in which items are separated one by one, inspected, and then sorted (sorted) based on the inspection, and supply, inspection, and sorting are performed at the same time. It is not configured to run. This reduces processing power and reduces the benefits of automation.

An object of the present invention is to eliminate such inconveniences during automation and to provide a highly accurate and efficient article inspection device.

[Means for solving problems]

The above purpose is to create a disk with separation grooves that match the size of the objects to be inspected, and by rotating the disk, the objects can be fed, inspected, and sorted simultaneously and processed. You can improve your abilities.

Positioning accuracy can also be improved by adjusting the size of the groove to the object to be inspected and reducing the margin.

[Effect]

The groove provided on the disc acts as a positioning function, and the four grooves each serve as a means of receiving and supplying articles.

This is a groove for inspection, removal of non-defective products, and removal of defective products.

These grooves enable the conveyance operation to be carried out in parallel rather than in series, thereby improving throughput.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to FIG.

FIG. 1 shows an example of a nut inspection apparatus, in which nuts to be inspected are manually placed into a hopper 1. The discharging row of the hopper 1 is provided with a pole feeder 2, and when the remaining amount of nuts in the pole feeder 2 becomes small, nuts are supplied from the hopper 1.

A linear feeder 3 is connected to the pole feeder 2, and the nut is discharged to the linear feeder by vibration of the pole feeder.

A disk 4 provided with a groove is connected to the linear feeder 3, and the linear feeder 3 serves to feed one nut into the groove of the disk 4.

The groove of the disc 4 has a space for inserting only one nut, and by rotating the disc 4, it is possible to cut out only one nut.

The disc 4 is provided with grooves at four locations, the positions of which are as follows:
They are arranged at angles of 90 degrees.

The main circumference of the disk 4 is the nut inspection machine 5. A good product chute 6 and a defective product chute 7 are arranged.

Now, the nuts discharged from the pole feeder 2 are fed to the disk 4 via the linear feeder 3, and as the disk 4 rotates, one nut is cut out and sent to the front of the inspection device 5. The inspection device 5 makes a pass/fail judgment, and at the timing when the disk rotates 90 degrees and a new test object is provided, if the product is good according to the previous judgment result, the air valve 13 on the non-defective chute side is released. and pay out to the non-defective side.

Inside the disc 4, as shown in Fig. 3, there is a pipe 4 for discharging air.
A is provided, and air piping is provided at the good product chute position and the defective product chute position. Connected to the air pipe are a solenoid valve 13 for discharging non-defective products and a solenoid valve 12 for discharging defective products, which are turned ON and OFF.

If the inspected item is defective, the solenoid valve 12 is controlled to be turned ON after moving twice, and discharged.

The rotation of the disc 4 is a tact operation in which the disc 4 rotates 90 degrees, stands still for a while, rotates 90 degrees again, and then stops, depending on the working number of the cam in the index unit 11.

These operations allow for smooth cutting, inspection, and delivery.

〔Effect of the invention〕

According to the present invention, only one object to be inspected is cut out.

Inspection and discharging of good and defective products can be done simultaneously, and processing capacity is vastly improved compared to conventional systems.

In addition, since the object to be inspected is accommodated in the groove of the disk, the object can be provided to the inspection device with high precision.

In addition, by stopping the disk, the influence of vibration is eliminated, and highly accurate inspection can be performed.

Claims (1)

[Claims] 1. A feeder for supplying the article to be inspected, a disk having at least four grooves around the circumference for receiving the article from the feeder, and a disk having at least four grooves around the circumference for receiving the article from the feeder; The feeder is arranged so as to receive the articles from the feeder, the inspection device is arranged at a position where the articles in the second groove can be inspected, and the sorting is carried out based on the inspection results at the positions of the third and subsequent grooves. What is claimed is: 1. A device for inspecting articles, characterized in that a sorting means for performing this is disposed, and the articles are sequentially supplied, inspected, and sorted in sequence while rotating the disc.
