Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal bottle can manufacturing apparatus.

[0002]

2. Description of the Related Art Generally, a metal bottle can (hereinafter simply referred to as a bottle can) is formed by drawing a metal plate made of aluminum or an aluminum alloy by drawing and then ironing it. Therefore, it is generally called a DI can.

Such bottle cans are widely used as beverage cans, and in the bottle can manufacturing apparatus,
Conventionally, when a bottomed tubular bottle can is formed from a metal plate, the bottle can is annularly arranged and supported on the outer periphery of a disc-shaped support, and the support rotates intermittently. As a result, the bottle can is rotated. On the other hand, an apparatus body that moves back and forth in the direction of the support is provided on the side facing the support, and a plurality of processing machines for processing bottle cans are provided in the apparatus body.

When the bottle can having a bottomed cylindrical shape is held by the support and the bottle can is gradually rotated by the support, a processing machine at a position corresponding to the bottle can sequentially operates the bottle can. By drawing and ironing, the diameter of the upper portion of the bottle can is gradually reduced (neck-in processing) to form a die having a diameter smaller than the body of the bottle can. In this case, since the die is drawn and ironed many times to be squeezed, the tip of the die has a wavy shape. Therefore, the trimmer machine adjusts the height (length) of the die. .

Next, after the base is formed and the length of the bottle can is adjusted, when the bottle can is further rotated and moved by the support, the screw part for attaching the cap to the base of the bottle can is screwed. It is formed by a forming machine, and then the curl forming machine bends the tip of the die outward to form a curl portion, and then the slot machine crushes the curl portion to form a curl crimp portion. .

When such a bottle can is subsequently filled with contents such as drinking water, a cap is attached to the mouthpiece to be manufactured as a product. When attaching the cap, when the cap is put on the cap, a screw corresponding to the screw part of the cap is formed on the outer periphery of the cap,
The cap is sealed to the base.

[0007]

In this manufacturing apparatus, when the bottle can held on the support is rotationally moved as described above, the processing machine at a position corresponding to the bottle can is moved forward to move the bottle can to the bottle can. On the other hand, when the processing machine performs the predetermined processing to form the mouthpiece on the bottle can and the heights of the mouthpiece are aligned, the screw portion, the curl portion, and the curl crimping portion of the mouthpiece are screw-forming machines, The curl forming machine and the slot machine are used to form the film sequentially.

However, the apparatus main body to which each of these processing machines is attached is configured to move back and forth in the direction of the support through the crank mechanism, and the operations thereof are repeated each time the support rotates. If it is done, the main body of the device will overheat and thermally expand, and as a result, each processing machine will move forward relative to the predetermined position relative to the bottle can.As a result, the length of the bottle can will be shortened and uneven during processing by the trimmer machine. In addition to the above, there is a problem that the screw portion, the curl portion, and the curl crimp portion are displaced from the predetermined positions with respect to the mouthpiece. Therefore, for example, when a screw part is formed on the base of a bottle can, the screw forming machine forms the screw part at a position closer to the bottom of the base of the bottle can. If a screw is to be formed on the cap, the position of the screw of the cap and the screw of the base will be displaced, and the screw cannot be formed on the cap at a position corresponding to the screw of the base.

The present invention has been made in view of such circumstances, and an object thereof is a bottle can manufacturing apparatus capable of performing a desired processing at a predetermined position on a bottle can even when it is thermally expanded. To provide.

In this embodiment, when the processing machine is moved forward to the bottle can A by the device body 20, the support 1
2 is provided with position regulating means 80 for regulating the processing machine at a fixed position.

As shown in FIG. 2, the position restricting means 80 includes a long body 81 extending toward the apparatus body 20 inside the accommodating portion 13 of the support 12 facing the trimmer machines 40A, 40. A stopper 82 is fixed to the tip, and a position regulating member 83 is fixed to a position corresponding to the stopper 82 in the trimmer machines 40A, 40. As shown in FIG. 3, the stopper 82 is attached to the tip of the elongated body 81 with a bolt 84 via an adjusting plate 85. The position restricting member 83 is attached to the tip of an arm 88 fixed to the housing 41 of the trimmer machine 40A, 40 by a bolt 87 and faces the stopper 82. The arm 88 is fixed to the housing 41 with a bolt 86.

Since the trimmer machines 40A, 40 are machined, the trimmer machine 4 is attached to the stopper 82 of the support body 12 when the apparatus body 20 moves forward toward the support body 12.
By contacting the position regulating members 83 of 0A and 40,
The position of the cutting blade 44 of the trimmer machine 40 can be regulated with respect to the bottle can A held in the housing portion 13.
That is, the position restricting member 83 comes into contact with the stopper 82 so as to define the most distal end position of the trimmer machines 40A, 40 when the apparatus body 20 moves forward.

The stopper 82 and the position restricting member 83 of the position restricting means 80 are the trimmer machines 40A, 40.
However, the curl forming machine 60, the slot machine 70, and the screw forming machine 50 have the same configuration. When the curl forming machine 60, the slot machine 70, and the screw forming machine 50 are machined, the apparatus body 20 moves forward. At this time, the position regulating member 8
3 is brought into contact with the stopper 82 so that each processing position is regulated to a fixed position. The screw forming machine 50
In FIG. 3, the position restricting member 83 is fixed to the tip of the rotating body 53, and the stopper (not shown) that abuts on the position restricting member 83 is fixed to the support body 20. Since it is a configuration, it is omitted in the drawing.

In this case, the housing 41 includes a bracket 92 fixed to the apparatus body 20 with bolts 91 and 95.
On the other hand, by being provided via the guide members 93 and 94, it is slidably attached in the axial direction parallel to the advancing / retreating direction of the apparatus body 20.

For processing, when the position regulating member 83 comes into contact with the stopper 82 due to the forward movement of the apparatus main body 20 and the forward movement amount of the apparatus main body 20 is large, the apparatus main body 20 tries to advance excessively and the housing The bracket 92 moves forward in 41, but the bracket 9
The excessive forward movement amount of 2 is absorbed by the spring force of the cushioning mechanism 90, so that the excessive forward movement of the apparatus main body 20 is absorbed.

The cushioning mechanism 90 is not limited to the trimmer machine 40 side, the trimmer machine 40A side, the curl forming machine 60 side as shown in FIG. 6, and the slot machine 70 side as shown in FIG. Since the screw forming machine 50 side, which does not have the same structure, has substantially the same configuration, further description will be omitted.

Since the manufacturing apparatus 10 of this embodiment is constructed as described above, its operation will be described below. First, a bottle can A formed into a cylindrical shape with a bottom by the previous step
When the bottles A are fed to the supply guide 16, the bottle cans A are sequentially supplied to the grip 17 of the supply means 15, and the grip 17
However, when it coincides with the accommodating portion 13 of the rotating support body 12, the bottle can A in the grip portion 17 is inserted into the accommodating portion 13. Then, by repeating this operation, the support 1
Bottle cans A are sequentially supplied to the respective storage units 13 on the upper part 2.

When the bottle can A is accommodated, the support 12 is rotated so that the bottle can A in the accommodating portion 13 is rotated.
When the device reaches the diameter reducing device 30, the device main body 20 moves to the support 12
Then, the diameter reducing machine 30 performs processing for reducing the diameter of the opening of the bottle can A (so-called neck-in processing). This diameter reduction processing is carried out by repeating oiling, drawing and the like a plurality of times.

Then, the mouthpiece B is formed on the bottle can A by the diameter reduction processing, and when the bottle can A having the mouthpiece B reaches the trimmer machine 40A.
A cuts the tip of the mouthpiece B of the bottle can A,
The lengths of the bottle cans A are adjusted and adjusted.

After that, when the rotation of the support 12 progresses and the bottle can A whose length has been adjusted reaches the expander 31, the expander 31 expands the once-reduced base B. Processing for forming the expanded diameter portion C is performed.

When the support 12 further rotates and the processed bottle can A reaches the screw forming machine 50, the screw forming machine 50 causes the screw expanding machine C to expand at a certain distance from the opening end of the mouthpiece B.
A threaded portion D is formed on. In this case, the screw forming machine 50
A process is also performed in which the expanded diameter portion where the threaded portion D is not formed is left as the bulging portion E.

This bottle can A is further provided with a trimmer machine 4
When it reaches 0, the trimmer machine 40 adjusts it by cutting the tip of the mouthpiece B to make the lengths uniform.
Then, when the adjusted bottle can A reaches the curl forming machine 60, the curl forming machine 60 folds the tip of the base B to the outside to perform a process of forming the curl portion F. After that, when the bottle can A having the curl portion F reaches the slot machine 70, the slot machine 70 crushes the curl portion F to perform a process of forming the curl crimp portion G.

The screw forming machine 50 and the trimmer machine 40A,
40, the curl forming machine 60, and the slot machine 70, when the apparatus body 20 is overheated and a portion fixing each processing machine is thermally expanded, the apparatus body 20 may move excessively forward from the set position. is there. However, this manufacturing apparatus 10 is provided with the position regulating means 80, and when the apparatus body 20 moves forward with respect to the support body 12, the stopper 8 of the position regulating means 80 fixed to the support body 12 is provided.
2, the processing machines 40A, 50, 4 of the apparatus main body 20
Since the position regulating member 83 fixed to the 0, 60, 70 side abuts, each processing machine can be regulated to the predetermined position with respect to the bottle can A.

At this time, if the apparatus main body 20 moves excessively, the position regulating member 83 and the stopper 82 may be destroyed, but the apparatus main body 20 side is provided with a buffer mechanism 90 composed of a coil spring. Since the excessive movement amount of the device body 20 is absorbed by the spring force of 90, the position regulating member 83 is prevented from pressing the stopper 82 with a strong pressure, and the device body 20 is moved forward to a predetermined position. However, there is no possibility that both 82 and 83 will be destroyed.

Therefore, even if the apparatus main body 20 thermally expands, the processing machines attached to the apparatus main body 20, that is, the trimmer machines 40A and 40, the screw forming machine 50, the curl forming machine 6 are provided.
Both the slot machine 70 and the slot machine 70 can be positioned at predetermined positions with respect to the bottle can A and can be processed as desired. As a result, a cap (not shown) is attached to the bottle can A in a later step. Therefore, if a cap screw is formed on the outer periphery of the cap, the cap screw can be accurately formed at a position corresponding to the threaded portion D of the base B, and the cap can be accurately formed. Can be surely adhered, and the bottle can can be manufactured well.

Further, according to this embodiment, as the position regulating means 80, the stopper 82 extending in the direction of the apparatus body 20 is provided on the support body 12, and the processing machines 40A, 50, 40, 60, Since the housing 70 is provided with the position restricting members 83 that come into contact with the stoppers 82, the structure can be reliably realized with a simple configuration.

Moreover, when the stopper 82 is attached to the elongated body 81 via the adjusting plate 85, the delicate positional relationship between the stopper 82 and the position regulating member 83 is changed by changing the thickness dimension of the adjusting plate 85. It can be corrected and can be easily and accurately dealt with when the device is installed. Further, since the buffer mechanism 90 is composed of the coil spring, it is possible to reliably absorb the excessive amount of forward movement of the device body 20 with a simple structure.

In the illustrated embodiment, the position regulating means 8
Although an example in which the 0 stopper 82 is provided on the support 12 and the position restricting member 83 is provided on the apparatus main body 20 side has been shown, it goes without saying that they may be provided in reverse. Also,
Device body 20 and processing machines 40A, 40, 50, 60, 7
An example in which a coil spring as a cushioning mechanism is contracted between 0 is shown, but an elastic body may be used instead, and the present invention is not limited to the illustrated example.
