Description

[0001] CAPPING MACHINE [0002]

The present invention relates to a cap capping apparatus capable of automatically stopping a capping roller when a coupling force of a cap coupled to a cap inlet reaches a predetermined value to perform a stable capping operation, To a cap capping device which can be used universally for a cap having a diameter and various shapes.

In general, chemicals, foods, or cosmetics are packed in containers for the purpose of preventing deterioration due to external bacteria, environmental factors such as temperature, humidity, etc., thereby enabling long-term storage and facilitating storage and transportation. The type of container used and the method of sealing the container are determined according to the type of the filling material.

That is, when the filling material is a consumable article such as a beverage or a liquid detergent, it is mainly contained in a container such as a metal can, a vinyl or a paper pack which can not be resealed once it is opened, and a cosmetic or food It is packed in a container equipped with a locking means so as to be milled and opened repeatedly.

Among the locking means, which can be repeatedly milled and unsealed, one method is to use a stopper. Among them, the outer circumference of the upper part of the container and the screw groove formed inside the stopper are rotated in the state of being fitted to each other, A screw cap which can be opened is often used.

An example of a device for capping the above-mentioned screw cap into a container is disclosed in Korean Utility Model Registration No. 20-0334513 and shown in Figs. 1 and 2. Fig.

This includes a conveyor belt 20 for moving the container 10 from the input position to the capping position and for withdrawing the container, a conveyor belt drive 120 for driving the conveyor belt 20, and a container conveyed by the conveyor belt A container clamping device 30 for clamping the container 10 transported to the capping position to fix the position of the container, A capping chuck 50 which is located at an end of the capping arm 65 and which performs capping by rotation; and a capping chuck 50 which drives the rotation of the capping chuck 50. [ A torque sensor connected to the capping rotation driving part 110 for sensing a torque applied to the capping chuck by a container lid and a sensor for detecting an initial height of the capping chuck 50 To change And a capping chuck height adjustment handle (60).

The apparatus enables automatic capping by changing the control conditions even if the size or shape of the container is changed by the conveyor belt height adjusting handle 100 and the clamping device 30. [

However, since the above-described apparatus requires separately a driving source for rotating the capping block 50, and a driving source for chucking or unchucking the container stopper, the structure is complicated and the manufacturing cost is increased.

In addition, in order to cap the spray cap as shown in FIG. 9 or the pump cap shown in FIG. 10, the capillary 50 having four jaws 55 needs to be different in size.

When the cap 101 is capped while being rotated in contact with the first and second capping rollers 160 and 170, the cap roller 101 is pressed against the first and second capping rollers 160 and 160, (170) so that the container (100) is separated from the capping position.

Referring to FIGS. 4, 7, 8, and 11, the first and second capping rollers 160 and 170 have first and second rotation axes 141 and 142, And first and second annular members 162 and 172 of an elastic material such as silicone detachably coupled to the outer circumferential surfaces of the first and second pulleys 161 and 171.

When the diameter of the cap 101 to be capped is different, the outer diameter D can be used by replacing the first and second annular members 162 and 172.

First, as shown in FIGS. 5 and 8, the moving block 190 is adjusted and fixed so as to match the diameter of the container 100, and the first and second capping rollers 160 ( 170 are adjusted so as to be positioned at the same height as the plug 101.

When the operator grasps the container 100 and puts the container 100 in close contact with the slope surface 192 of the moving blocks 190, the detection sensor 200 senses the container 100 to operate the rotating cylinder 210, The pressing roller 211 is rotated so that the pressing roller 212 is brought into close contact with the outer peripheral surface of the cap 101. [

The driving motor 150 is driven about one second after the sensing signal of the sensing sensor 200 to drive the first and second capping rollers 160 and 170 to cap the cap 101.

At this time, the driving of the driving motor 150 is stopped when the first and second capping rollers 160 and 170 rub against the cap 101 to reach the set torque value during the rotation at the predetermined speed, The reverse rotation of the rotary cylinder 210 releases the pressure roller 212 from the stopper 101 so that the operator grips the capped container 100 to release it from the capping position and lifts the container to be capped to the capping position So that the capping operation as described above is continuously performed.
