DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing an outer cylinder of a dry battery.

[0002]

2. Description of the Related Art In general, an outer cylinder of a dry battery is formed by forming an original plate, which is a rectangular thin metal plate, on a surface of which is printed with required lexical characters, patterns, etc. in advance, by abutting a pair of corresponding side edges thereof to form a cylinder. After rounding, it is obtained by curling both end edges inward.In this case, in the case of an outer casing having a certain size or more, it is possible to provide a bent edge portion at the abutting portion and fix them to each other by appropriate means. Is being done. However,
In the case of a small-sized one, for example, an outer cylinder used for a 1.5-volt AA or AAA battery, the outer cylinder is merely abutted, which means that the words and patterns printed on the outer surface are abutted. In addition to the problem of appearance in order to prevent displacement, a set of butted side edges must be formed exactly in a single step. In addition, it is necessary to mass-produce an outer cylinder having a required diameter with a good yield at a high speed.

[0003] As a conventional apparatus for manufacturing such an outer casing of a dry battery, for example, there is a technique as shown in Japanese Patent Publication No. 59-35689. That is, FIG. 11 and FIG.
As shown in FIG. 2, in a base frame 2 provided on a base 1, a peripheral surface is supported by four guide rollers 3, and a short cylindrical drum 4 engages an outer peripheral tooth surface with a spur gear 5. 11 and is rotated counterclockwise in FIG. 11 from a drive shaft 6 connected to an appropriate drive mechanism via a chain wheel 7, 8 and a gear 9 meshing with the spur gear 5. On the other hand, cams 10 and 11 are attached to the shafts of the chain wheels 7 and 8 located in the base 1, respectively.
Via 0 and 11, a workpiece pushing mechanism 12 and an original sheet feeding mechanism 13 provided on the same line as viewed from the front and rear direction are operated.

As shown in FIG. 12, the short cylindrical drum 4 penetrates the base 1, and a guide rod 14 of a workpiece pushing mechanism 12 and a small-diameter rotary cylinder are provided near the inner peripheral surface thereof. 15. A comb-shaped regulating plate 16 is mounted horizontally from above in order. The rotary cylinder 15 rotates at a high speed through gears 17 meshing with the outer peripheral tooth surface of the drum 4. The rotary cylinder 15 rotates with a required original plate 0 interposed between the rotary cylinder 15 and the inner peripheral surface of the drum 4. The original plate 0 is wound around the peripheral surface of the rotary cylinder 15 to form a cylindrical shape. An ejection claw 18 connected to the workpiece pushing mechanism 12 is fitted to the guide rod 14, and the ejection claw 18 slides around the peripheral surface of the rotating cylinder 15 via the arm 19 by the cam 10. By doing so, the processed product is pushed outward from the rotary cylinder 15.

[0005] The regulating plate 16 is adapted to move the original plate 0 inserted between the rotating cylinder 15 and the inner peripheral surface of the drum 4 to the rotating cylinder 15.
It is fixed obliquely upward so as to fit into the inner peripheral surface of the drum 4. The height is adjusted via the adjusting screws 20, 20. I have. On the inner peripheral surface of the drum 4, opposed thick portions 21 and 21 and thin portions 22, which are defined by lines along the axis of the drum at positions dividing the circumference into four parts, are formed.

[0006] Between the inner peripheral surface of the drum 4 that rotates continuously and the peripheral surface of the rotary cylinder 15 via gears 17 meshing with the outer peripheral tooth surface of the drum 4 of the outer cylinder of the dry battery, When one of the thick portions of the peripheral surface comes just above the rotary cylinder 15, the original plate 0 is fed by the original plate feeding mechanism 13, and the leading end of the fed original plate 0 has a regulating plate below the rotary cylinder 15. 16, is guided along the peripheral surface of the rotary cylinder 15, and is pressed between the inner surface of the thick part 21 and the peripheral surface of the rotary cylinder 15 until the thick part 21 passes therethrough. It is wound around the rotating cylinder 15 via the rotation of the cylinder 15. In this way, when the thick portion 21 passes and the thin portion 22 reaches, the cylindrical original plate is simply fitted into the rotary cylinder 15 as a processed product, and the processed product is extruded here. The take-out claw 18 slides via the mechanism 12 and pushes out the cylindrical original plate from the rotary cylinder 15.

[0007]

According to the prior art as described above, the cams 1 attached to the shafts of the chain wheels 7 and 8 located in the base 1 respectively.
Since the workpiece pushing mechanism 12 including the guide rod 14, the arm 19, and the take-out claw 18 and the original plate feeding mechanism 13 are provided via the reference numerals 0 and 11, the structure becomes complicated, and the outer cylinder is manufactured by changing the diameter of the outer cylinder. In such a case, it is troublesome to replace parts such as the rotary cylinder 15 that is rotated via the gear 17 meshing with the outer peripheral tooth surface of the drum 4.
Also, the adjustment of the mounting of the guide rod 14 and the regulating plate 16 is troublesome. Further, since the rotary cylinder 15 rotates through the gear 17 meshing with the outer peripheral tooth surface of the drum 4, there is a limit to the high-speed rotation of the drum 4, and the structure of the workpiece pushing mechanism 12 is complicated. Accordingly, there has been a problem that it is difficult to mass-produce an outer cylinder having a required diameter with a good yield at a high speed. Therefore, an object of the present invention is to solve the problems of the related art as described above,
When manufacturing by changing the diameter of the outer cylinder, the outer cylinder of the dry battery that enables easy replacement of parts (free rotating cylinders) with certainty, and enables easy high-speed mass production with high yield of the outer cylinder An apparatus for manufacturing is provided.
