Description

[Detailed Description of the Invention] This invention relates to a device for attaching a cap fitted into the mouth of a teapot, water jug, or other drawn product.

The edge of the mouth where the lid of the squeezed product is dropped can be dangerous if left uncut, so it is processed to prevent damage to hands.

In the above process, the edge of the mouth was conventionally rolled up using a roll-formed plate, so cracks appeared during rolling-forming.
It is easy to produce defective products.

This invention aims to solve the above-mentioned drawbacks by fitting the cap into the mouth and fixing the cap with a roll-formed plate.

This idea involves fitting a separately processed cap into the mouth of a drawn product, and moving at least a pair of bottom-shaped rolls in opposite directions to wrap around the edges of the cap and fix the cap to the mouth. Installation of equipment provided.

Embodiments of this invention will be described below with reference to the accompanying drawings.

In the figure, 1 is an annular receiving plate on which the drawn product A is placed.
On the upper edge of the inside diameter of this receiving plate 1, there is an annular protrusion 2 that fits into the mouthpiece B that has been fitted in advance into the mouth a of the drawn product A.
is provided.

The above-mentioned receiving plate 1 is removably set by fitting into the upper end of the cylindrical seat member 3, and can be replaced by selecting a receiving plate 1 having a protrusion 2 having a diameter that matches the diameter of the base B. It has become.

Further, a cylindrical rotating body 5 is provided below the receiving plate 1 to apply an upward restoring force by a spring 4 and to be driven as the plate descends.

The rotating body 5 is driven by passing a belt 9 between a pulley 6 provided on the rotating body 5 and a pulley 6 of the motor 7, and turning on a switch (not shown) as the rotating body 5 descends. The operation of motor 7 is started.

Furthermore, a plurality of sliders 11 are provided at the upper end of the rotary body 5 to apply a restoring force toward the center using a spring 10 and to move the same distance outwardly when the rotary body 5 descends.

In the illustrated case, the slider 11 has a horizontal square hole 12 extending from the inner circumferential surface of the rotating body 5 to the outer circumferential direction.
A rectangular slider 11 is fitted in the.

The method of moving the slider 11 is as follows:
The shaft member 13 is penetrated through the shaft member 13, and a tapered member 14 is fixed to the upper end of the shaft member 13 so as to be in contact with the inner upper edge of each slider 11. As the shaft member 13 descends, each slider 1
1 is pushed out.

In order to lower the shaft member 13, in the illustrated case, the tip of the petal arm 15, which is lowered by pressing the pedal, is connected to the lower part of the shaft member 13, but the shaft member 13 may be lowered by applying a cylinder to the lower part of the shaft member 13 by pressing the foot pedal. .

Furthermore, a pillar 16 penetrating through the center of the receiving plate 1 is provided at the inner end of each slider 11, and on the outer surface of the upper end of the pillar 16, the edge of the base B is rolled and molded via a horizontal pin 17. A roll 18 is attached.

Further, a pressing plate 2 is provided directly above the center of the receiving plate 1, which presses the drawn product A onto the receiving plate 1 by the expansion action of the cylinder 19.
0 is set.

The expansion action of the cylinder 19 is such that it expands as the shaft member 13 descends.

Note that the cap B includes a U-shaped bent wall 21 and this bent wall 2.
a horizontal wall 22 that continues from the inner wall of 1 and protrudes inward;
It is constituted by a vertical wall 23 extending vertically from this horizontal wall 22.

In the figure, 24 is a spring that provides upward restoring force to the shaft member 13, and 25
26 is a table, 26 is a support arm of the cylinder 19, 27 is a set screw for supporting the pin 17 on the pillar material 16, and 28 is a notch provided in the receiving plate 1 so that a piece of the drawn product A fits into it.

The device for attaching the nozzle according to this invention has the above-mentioned structure, and its operation will be explained next.The nozzle B is previously fitted into the nozzle a of the drawn product A.

]7 After fitting the cap B to the protrusion 2 and placing the drawn product A on the receiving plate 1, when the shaft member 13 is lowered,
While driving the rotating body 5 in one direction, the tapered member 14
Since each slider 11 is slid by the same distance in opposite directions, the forming roll 1 is placed on the vertical wall 23 of the base B.
8 are in contact with each other, and the vertical wall 23 is bent by the movement and rotation of the forming roll 18 (as shown in FIG. 8), and the mouthpiece B is rolled into the mouthpiece a.

After the cap B is attached, the shaft member 13 is raised and returned to its original position.

Note that there is a shaft material 1 on the bottom of the drawn product A placed on the receiving plate 1.
As the shaft member 13 descends, the pressing plate 20 is brought into pressure contact via the cylinder 19 which acts to expand, and the drawn product A is pressed onto the receiving plate 1. As the shaft member 13 rises, the cylinder 19 is caused to contract, and the drawn product A is pressed. Release the pressure.

As the shaft member B returns upward, the slider 11 is returned inward by the spring 10.

As described above, according to the apparatus for attaching the cap according to this invention, the cap is fitted into the mouth of the drawn product, and the drawn product is placed on the receiving plate so that the cap fits into the protrusion. After that, when the shaft member is lowered, the rotary body is driven, and while the slider is slid by the same distance in opposite directions, the vertical wall is rolled up by the forming roll that comes into contact with the vertical wall of the cap. Since it is bent into a shape so that the cap can be attached to the mouth, the cap can be attached easily and reliably.

Further, the mouth can be reinforced by the mouthpiece, and even if there is a crack in the mouth, the crack can be covered by the mouthpiece.
