Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a product inspection device for inspecting a large number of electrical devices and the like.

(Prior Art) Conventionally, for example, in a production line for electrical equipment, when a large number of electrical equipment is tested for electrical current,
In many cases, individual items are inspected one by one. However, such an inspection method is very time-consuming.

Conventionally, a power feeding type pallet has been used, electrical equipment mounted on the pallet is connected to the power feeding part of the pallet, and the electrical equipment is transported along with the pallet by a conveyor while being inspected.
In this case, if the product is defective, it is removed from the conveyor or guided to a branch line, adjusted or repaired, and then inspected again on the inspection line, which again takes time.

(Problems to be Solved by the Invention) As described above, conventionally, inspection and re-inspection of products such as electrical equipment requires a lot of effort and time.

An object of the present invention is to enable efficient inspection and re-inspection of a large number of products.

[Structure of the invention]

(Means for Solving the Problems) The product inspection device of the present invention includes a conveyor that sequentially conveys a plurality of products, and a conveyor that is provided so as to be able to appear and retract from the conveyance surface of the conveyor at predetermined intervals to convey each of the above-mentioned products. a plurality of stoppers for stopping at predetermined intervals along the direction; and a plurality of stoppers provided along the side of the conveyor and corresponding to the positions of the products stopped by the stoppers on the conveyor to inspect each product. a moving mechanism that moves each product stopped by each stopper between a stopping position on the conveyor and an inspection position by the inspection mechanism removed from the conveyance surface of the conveyor; It is equipped with the following.

(Function) In the present invention, the products 25 are sequentially carried onto the conveyor 13 and transported, and each stopper 14 is sequentially projected onto the transport surface from the downstream side of the conveyor 13 to move each product 25 along the transport direction. and lock it at predetermined intervals.

Then, each moving mechanism 17 operates simultaneously to remove the product 25 from the conveyance surface of the conveyor 13, place the product 25 against the inspection mechanism 15, and place the product 25 against the inspection mechanism 15.
Perform each of the 5 tests individually.

For products 25 determined to be non-defective by this inspection, the corresponding individual moving mechanisms 17 move to return the products 25 onto the conveyor 13 and carry them out.

On the other hand, for a product 25 determined to be defective, the moving mechanism 17 corresponding to the product 25 does not operate and is left at the inspection position, where adjustment or repair is performed.

Also, the product 25 determined to be good is transferred to the conveyor 1.
3, the next products 25 are carried onto the conveyor 13 by the number of good products that have been carried out.
In the empty frontage that was previously carried out as a non-defective product, the product 25 is stopped sequentially from the downstream side to the upstream side by the stopper 14 corresponding to the opening, and is sent to the inspection mechanism 15 side in the same manner as above, and the product 25 is inspected. is carried out, and the non-defective products 25 are carried out.

At this time, the product 25 that was determined to be defective in the previous inspection and for which adjustment or repair has been completed is re-inspected at the same time as the new product 25, and if it is found to be a good product, it is transported out.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

Reference numeral 11 denotes a frame, and a conveyor 13 in which a large number of drive rollers 12 are arranged in parallel on a shaft is provided on the frame 11, and a plurality of stoppers 14 are provided between the rollers 12 at predetermined intervals on this conveyor 13 so as to be able to appear and retract. ing.

Inspection mechanisms 15 are provided on the frame 11 along one side of the conveyor 13 in a positional relationship corresponding to each stopper 14, and a power supply section 16 is provided inside the inspection mechanisms 15. Furthermore, a lateral movement mechanism 17 is provided on the frame 11 between the conveyor 13 and each inspection mechanism 15. In this moving mechanism 17, a moving table 19 is connected to the upper part of a cylinder device 18, and pushing bodies 20 and 21 are provided on both upper sides of this moving table 19.

Reference numeral 23 denotes a pallet, and a support plate 24 is erected on one side upper part of the pallet 23, and a product 25, which is an electrical device, is mounted on the outer surface of the support plate 24.

Then, the pallets 23 loaded with the products 25 are sequentially carried onto the conveyor 13 and conveyed, and at the same time, each stopper 14 is sequentially projected onto the conveying surface from the downstream side of the conveyor 13, and each pallet 23 is moved in the conveying direction. along the line at predetermined intervals.

At this time, the moving table 19 of the moving mechanism 17 is located between the rollers 12 on the right side in FIG. Use this as a guide.

Then, when the pallets 23 are stopped by the respective stoppers 14 on the conveyor 13 and a predetermined number of pallets 23 are placed on the conveyor 13, the respective moving mechanisms 17 are operated simultaneously, and the cylinder device 18 moves the moving table 19 onto the conveyor 13. As a result, the pushing body 20 moves the pallet 23 to one side perpendicular to the conveyance direction, removing it from the conveyance surface of the conveyor 13 and moving the contact part of the product 25 to the inspection mechanism 15 side. It is brought into contact with the power supply section 16 and set as shown in FIG. As a result, each product 25 is energized at the same time and each product 25 is individually inspected.

In this way, each product 25 is inspected by being energized for a predetermined period of time, and for products 25 determined to be good by this inspection, the corresponding individual moving mechanism 17 is activated, and the first By moving to the right in the figure, the pushing body 21 pushes the pallet 23, returns it to the conveyor 13, and moves it to each stopper 14.
It is carried out as it descends and sent to the next process.

On the other hand, for a product 25 determined to be defective, the moving mechanism 17 corresponding to the product 25 does not operate and is left at the inspection position, where adjustment or repair is performed.

In addition, Palette 2 of 25 products determined to be good products
3 is carried out from the conveyor 13, the next pallet 23 corresponding to the number of good products carried out is carried onto the conveyor 13, and the stopper 1 corresponding to the empty frontage from which the good products were carried out first is placed.
4 from the downstream side to the upstream side, and sent to the inspection mechanism 15 side in the same manner as above, where the product 25 is inspected and the product 25 is found to be a good product.
will be carried out.

At this time, the product 25 that was determined to be defective in the previous inspection and for which adjustment or repair has been completed is re-inspected at the same time as the new product 25, and if it is found to be a good product, it is transported out.

In addition, during implementation, the inspection mechanisms 15 are provided on both sides of the conveyor 13, and the pallets 23 are alternately arranged in the left and right inspection mechanisms 15 by the moving mechanism 17, thereby making inspection of a large number of products 25 more efficient. can do well.

〔Effect of the invention〕

According to the present invention, multiple products can be inspected at the same time, good products and defective products can be determined, and non-defective products can be transported out, and defective products can be re-inspected immediately at the same location after adjustment or repair. It is possible to carry out continuous and efficient inspection of products.
