DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the manufacture of rod-shaped articles for checking the total length of rod-shaped articles, such as candy and cotton swabs, made of paper, plastic, etc., on a line and eliminating defective lengths. The present invention relates to an apparatus for inspecting the product length of a machine.

[0002]

2. Description of the Related Art Conventionally, the length of a bar-shaped article (product) such as a candy or a cotton swab made of paper, plastic, or the like has been measured by an inspector by appropriately extracting the product from the finished product. However, this method has a problem that the frequency of inspection increases with the need for improving the quality (dimensional accuracy) of the product and the speeding up of the production line, thereby increasing the burden on the inspector. Further, in the bar-shaped article, a defective length is generated due to a length tolerance, a shape of the cut end face, and the like in the processing of the end cutting, so that it is best to perform a 100% inspection.

[0003]

SUMMARY OF THE INVENTION In view of the above, the present invention provides a product length inspection apparatus for a bar-shaped article manufacturing machine capable of inspecting the entire length of a product without manual operation and eliminating defective products. The purpose is to provide.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a bar-shaped article manufacturing machine for measuring the entire length of a molded bar-shaped article with an inspection drum in a process and discharging defective-length products. A product length inspection device, wherein the inspection drum comprises a drum main body having a product receiving portion, a spring disk disposed opposite to the front and rear of the drum main body, and a floating disk which can be tilted and rotated; An inclined support portion for inclining and supporting the floating disk so as to hold a product between the spring disk and the floating disk, and a length installed opposite to the spring disk corresponding to the apex of the inclined support portion A conveyance drum for receiving a product from the drum main body adjacent to the inspection drum, and discharging a defective length product based on a signal from the length sensor. Characterized in that it has a discharge means for.

[0005]

The product picked up by the drum body is held by the spring disk between the floating disk and the spring disk which are supported by the inclined support portion and held by the spring disk. Then, the length sensor detects the position of the rotating spring disk which holds the product, facing the rotating spring disk, and indirectly measures the total length of the product. Then, the defective product is automatically eliminated by the discharging means of the transport drum.

And the length sensor 21.

As shown in FIG. 4, the drum main body 10 has the product receiving portion 9 provided at the center of a cylindrical boss portion 13, and a V-shaped or the like is provided around the receiving portion 9. Product receiving groove 14
Is formed. In the product receiving groove 14, as shown in FIG.
The product 2 is delivered from the lower pickup drum 3. The drum body 10 and the pick-up drum 3 are connected to gears 15 and 16.
Rotate synchronously via.

The spring disk 11 is attached to the boss 13 of the drum body 10 via a collar 17 in a forward direction.
The floating disks 12 are fitted to the rear. The spring disc 11 has a plurality of spring pieces 19 radially provided around a fixing ring 18, and a metal plate having a flat part 20 a on the outside and a pin part 20 b on the inside at the tip of the spring piece 19. 20 are provided. As shown in FIG. 3, on the outside of the metal plate 20, a length detecting sensor 21 is installed so as to face the metal plate 20. The length sensor 21 is
It is fixed to a tower 22 provided on the side of the drum 4 so that the displacement can be adjusted. Further, one end of the product 2 can be in contact with the inner side surface 20b of the metal plate 20, and the other end of the product 2 is in contact with the floating disk 12.

The floating disk 12 is shown in FIG.
4, the inner ring 23 is fitted and fixed to the boss 13 of the drum body 10, and includes a middle ring 24 and an outer ring 25 that can swing around the inner ring 23 in the orthogonal direction. A plurality of product contact pin portions 27 are provided on an outer peripheral flange portion 26 of the outer ring 25.
Is provided. The middle ring 24 and the outer ring 25
The pin is supported on two sides orthogonal to each other, and can swing around the drum body 10.

The floating disk 12 is rotatable in a state of being inclined by an inclined support portion 28 disposed opposite the rear of the disk 12. The inclined support 2
Reference numeral 8 denotes a slant ring 29 made of metal and a contact bolt 30 for inclining the ring 29. As shown in FIG. 4, the slant ring 29 is supported by upper and lower ends by receiving portions 31 and can be inclined by pushing up a bracket 32 projecting from one side end with a corresponding contact bolt 30. A plurality of rollers 33 are provided inside the slant ring 29.
Is rotatably supported, and the floating disk 1
