Description

[0001] CASE SEAMING APPARATUS [0002]

[0001] The present invention relates to a can seaming device, and more particularly, to a can-seaming device, in which a can lid is placed on an upper surface of a can, .

It is a well-known fact that cans are generally used for packaging various contents such as drinks and foods.

In order to manufacture such a can, various methods have been used. Among them, most typical ones are a method in which a can is first formed by winding or bending a plate material having a predetermined length to form a cylinder or a square barrel, A can lid in the form of a disk or a rectangular plate is provided on the upper and lower surfaces of the can, and is integrally sealed together with the can.

However, in the related art, there has been a problem that productivity and operability due to the can production are inferior due to the manual operation of each operation for sealing the lid of the can body in order to manufacture a can having a cylindrical or rectangular cylinder shape.

[

The rotary plate 28 rotates the can lid 600 by the power of the motor 22 in a state of being closely attached to the upper surface of the can lid 600 which is moved up and down by the operation of the can supporting means 10 .

The shim means 30 is located behind the can lid rotating means 20 and the can lid 600 placed on the can 500 by the can lid rotating means 20 is moved to the can 500, When the can lid 600 is rotated together with the can lid 600, the rim of the can lid 600 is pressed around the rim of the can lid 600 to wind the rim of the can lid 600 along the outer circumferential direction of the can 500.

FIG. 4 is a three-dimensional view of the structure of the above-mentioned seaming means, and FIG. 5 is a view showing the plane of FIG.

4 and 5, the seaming means 30 is installed vertically in the rear of the can lid rotating means 20 and is installed at the lower end (that is, inside the base 200) A cam 34 which is coupled to an outer diameter of the camshaft 32 and has an eccentric curved surface bent at a predetermined angle on an outer circumferential surface thereof, A cam roller 36 which is in contact with an outer circumferential surface of the cam 34 and slides on the outer circumferential surface of the cam 34 and an end is bolted to the cam roller 36, A bolt 39 is coupled to the tip of the arm 38 and is engaged with the arm 39 in accordance with the operation of the arm 39. [ The edge of the can lid 600 is pressed so that the edge portion of the can lid 600 And it comprises a seaming roller 40 for winding the sealing along the outer circumferential direction of the can (500).

It is preferable that the cam 34 and the cam roller 36, the arm 38 and the seaming roller 40 have the same structure and a plurality of the cam 34, the arm 38 and the seaming roller 40 are arranged so as to face each other, A detailed description thereof will be omitted.

The guide means (50) is means for guiding the inside air gap and the outside air gap of the arm (38) constituting the seaming means (30).

The guide means 50 is welded to the outer diameter of the block 25 fitted to the outer diameter of the shaft 26 for rotating the rotary plate 28 which is the can lid rotating means 20, And the arm 38 is screwed and fixed to the arm 38 serving as the seaming means 30 in a state in which the guide block 52 passes through the guide slot 52 of the guide block 52, A coupling pin 56 moving along the guide slot 54 according to the operation of the arm 38 and guiding the operation of the arm 38 and a coupling pin 56 inserted into the guide slot 54, And a spring 58 for resiliently supporting it.

Hereinafter, the operation of the can seaming apparatus according to the present invention will be described with reference to FIGS. 5 and 6. FIG.

When the can lid 600 is to be sealed on the upper surface of the can 500 using the can shimming apparatus 100 of the present invention, first, as shown in Fig. 6, on the die 12 as the can supporting means 10, The elevating means 14 ascends and descends and the can lid 600 of the can 500 placed on the die 12 is moved up to the bottom of the can 500, And is brought into close contact with the bottom surface of the rotary plate 28 which is the lid rotating means 20.

Next, power is applied to the motor 22 serving as the can lid rotating means 20 to rotate the rotary plate 28 closely attached to the upper surface of the lid 600, and then the seaming means 30 is operated The edge portion of the can lid 600 is pressed by the seaming roller 40 and the rim portion of the can lid 600 in the rotating operation is wound around the outer circumferential direction of the can 500 to be sealed.

6, when the motor 31 is driven to rotate the camshaft 32, the cam 34 coupled to the outer diameter of the camshaft 32 is rotated, and at the same time, The cam roller 36 contacting the outer peripheral surface having the eccentric curved surface of the arm 34 tilts the arm 38 at a predetermined angle in the course of sliding on the outer peripheral surface of the cam 34, 38 are gathered inward and at the same time the seaming roller 40 which is coupled to the tip of the arm 38 is brought into contact with the rim of the lid of the lid so that the rim of the lid 600 in the course of the rotation can be put into the can (500).

At this time, when the arm 38 serving as the seaming means 30 is to be gathered inward, the engaging pin 56 coupled to the arm 38 is guided by the guide slot 52 of the guide block 52, The operation of the arms 38 is guided by moving along the guide lid 54 to guide the movement of the arm 38. When the seaming operation between the can 500 and the lid 600 is completed and the spring 58 The arm 38 pushes the arm 38 outward so that the arm 38 returns to the initial state.
