Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the field of conveyor belts for cold heading of bolts, nuts, etc.

(Prior art) Devices for conveying bolts, nuts, etc. manufactured by conventional cold heading include vibration conveyance, chain-type belts with hooks,
Many existing devices existed, such as conveyors using rubber or cloth belts and those with hooks attached to rubber or cloth belts, but rubber or cloth belts were unable to withstand heat or were oil-resistant. There are also problems with metal belts, in which the workpiece cannot be moved unless a hook is installed, and in particular cannot be moved upwards, and vibrating belts have high vibration noise. This has caused noise pollution and hearing loss, and has also caused problems such as dents and other scratches on the product and severe wear and tear.

(Problems to be solved by the present invention) The present invention eliminates the above-mentioned conventional defects all at once, and can transport bolts, nuts, etc. by cold forging in a sequential manner. This eliminates the need for special hooks and the like used for moving.

(Means for Solving the Problems) The present invention has a driven shaft in the front part of the frame having a predetermined width and a predetermined length, which is perpendicular to the frame, and the other driven shaft in the rear part of the frame. The shafts are mounted perpendicularly to the frame, a sprocket gear is mounted on the main drive shaft, and a drive chain is wrapped around the drive part and sprocket gear of the motor mounted on the upper part of the frame. Column-shaped rollers made of metal or the same material with connection parts at both ends are arranged closely in parallel, and the connection part of each roller is wrapped around the sprocket gear and the rotating body attached to the driven shaft. This is a conveyor belt for cold heading of bolts, nuts, etc., which is connected to a chain and tensioned from the lower part of the connected roller and chain.

(Example) An example of implementing the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a frame body formed with a predetermined width and a predetermined length constituting the conveyor a for cold heading of bolts, nuts, etc. of the present invention. Reference numeral 2 denotes a driven shaft mounted at right angles to the front part of the frame 1, and a rotating body 3 is attached to the shaft 2. Reference numeral 4 denotes a driving shaft mounted at right angles to the frame 1 at the rear of the frame 1, that is, on the opposite side to the driven shaft 2, and a sprocket gear 5 is coaxially mounted on the shaft 4. do. Reference numeral 6 denotes a motor mounted above the main drive shaft 4 and sprocket gear 5 and above the frame body 1 via a support frame part 7,
A drive chain 8 is placed around this motor 6 and sprocket gear 5. Reference numeral 9 denotes a cylindrical metal roller constituting the conveyor belt of the present invention, and the roller 9 has connecting portions 10 formed at both left and right end portions, respectively. Roller 9 as above
After arranging the rollers 9 in close contact with the left and right edges of the frame 1 in the same direction (perpendicular to the length direction of the frame), the connecting portions 10 of the rollers 9 are connected. At the time of this connection, it goes without saying that the bolts, nuts, etc. should be connected so that they do not fall from between the rollers 9 that are in close contact with each other. Each roller 9 connected as described above is connected to a connecting portion 10 of the roller 9, a rotating body 3 attached to the sprocket gear 5, and the driven shaft 2.
A belt 12 is constructed by connecting a chain 11 which is wrapped around the belt so as not to separate from the chain 11. Therefore, the belt 12 assembled via the rollers 9 is rotated from the upper part to the lower part of the frame 1 and from the lower part to the upper part at a predetermined speed by the above-mentioned interlocking mechanisms. Numeral 13 is a tension part that presses the belt 12 from the lower part of the frame 1, and 14 is a leg part that adjusts the height of the frame 1 to a predetermined height, and the shape thereof is not limited as shown in the drawing. . 15 is a guard attached to the side of the frame 1, and 16 is a recess formed between each roller 9.

(Function) To explain the function of the present invention, when the motor 6 as the drive source is operated, the driving force of the motor 6 rotates the sprocket gear 5 through the chain 8 at a predetermined speed, and the sprocket gear 5 is rotated at a predetermined speed. A chain 11 that is wrapped around the rotating body 3 and a belt 12 that is made up of rollers 9 that are connected to the chain 11 rotate simultaneously. Further, the belt 12, which moves in a predetermined direction, moves from the upper part of the frame body 1 to the lower part. When a bolt, nut, etc. manufactured by cold heading falls onto the belt 12 of the present invention, all or part of the head, legs, etc. that make up the bolt, nut, etc. make up the belt 12. are doing. roller 9
Although there are various shapes in which the frame 1 falls into the recess 16 between the frames 1 and 16, it remains in its initial state where it falls and remains stationary when being transported from one end of the frame 1 to the other end. , there will be no unexpected movement.

Furthermore, since the belt 12 is tensioned by the tension portion 13, the belt 12 does not vibrate vertically during conveyance. Therefore, bolts, nuts, etc. placed on the roller 9 do not move.

(Effects) (1) The present invention improves the structure of a conveyor belt for conveying bolts, nuts, etc. manufactured by cold heading, by installing cylindrical rollers made of metal material or the same material on the left and right sides of the frame. After connecting the connecting parts of each roller in the same direction as both side edges (perpendicular to the length direction of the frame) and closely paralleling them, the chain (sprocket gear and driven shaft) Since the belt is assembled by connecting all the rollers to the belt (which runs around the body), even if bolts, nuts, etc. manufactured by cold heading fall onto the belt, they will not fall into the recesses formed between the rollers. This has the advantage that bolts, nuts, etc. do not get stuck in whole or in part and move on the rollers during conveyance in an inclined state, and therefore do not cause damage to the product.

(2) Furthermore, since the belt of the present invention has sufficient heat resistance and oil resistance, the belt has a long service life and is sufficiently economical.

(3) Furthermore, the present invention is manufactured using a simple assembly process in which the rollers are simply arranged in close contact in the same direction as described above and all the rollers are connected. Thus, there is no need to install a hook, so it has the advantage that it can be manufactured at low cost.
