Abstract

The present invention relates to a collet chuck system, and a servo motor and a torque, capable of holding and closing a cap in a capper used for closing a mouth of a container with the cap. When chuck pusher is moved forward by injecting air through a shaft under the principle of an air chuck, a chuck jaw attached to the chuck pusher is pushed along an inclined surface and the chuck jaw is contracted to allow a pad, connected to the chuck jaw, to hold the cap. The present invention comprises a capping rotation servo motor operating the rotation of the collet chuck; a torque connected to the capping rotation servo motor to sense rotational force applied to the capping collet chuck; and a control condition input device connected to a control part to combine the cap with the neck of the container. Therefore, the cap is strongly combined with the container, an error rate is reduced, and working speed becomes faster. Moreover, the cap is combined with the neck of the container by proper rotational force by operating the servo motor at the torque, set by a numerical control method, and therefore, the error rate is more reduced by preventing damage to the cap.

Description

[0001] The present invention relates to a silicon pad collet chuck, a capping machine without scratch,

The present invention relates to a silicon pad collet chuck and a capping machine to which a sub motor and a torque are applied in order to prevent damage to the outer surface of the cap when locking the cap which closes the container of the container containing the contents and to ensure reliable locking.

In modern society, the production and distribution structure of goods is structured such that large quantities of goods are produced in factories and small quantities are supplied to consumers.

In such a structure, a process of packing a small amount of goods in order to supply a small amount of goods to a consumer is required. Among the packing methods, a method of packing an article in a container and capping the opening of the container is widely used.

A capping machine such as the Korean Patent Application No. 10-2005-0046981 has been developed in order to make the packaging process using such containers and caps automatic or semiautomatic.

These cappers combine the container and cap supplied through the conveyor, respectively, at a specific point.

Therefore, the capper is provided with a clamp for holding the cap and a moving means for moving the cap fixed to the clamp in the container direction to move the cap in the container direction and to couple the container to the container.

The conventional clamp has a configuration in which a plurality of pressure plates are fixed by pressing various points of the cap or a method of fixing the cap by using an attraction force.

However, the above-described fixing method has a problem that when the cap is coupled to the container, the failure rate of the coupled state is high and the time required for bonding one container and the cap is long.

That is, the container and the cap are not firmly coupled to each other, and the contents are leaked, or the container is coupled to the container in a state in which the container is not tightly sealed.

And the biggest problem is that the torque is not adjusted when assembling to the container by rotating the cap by holding the cap, so that the appearance of the cap is damaged and the product value is deteriorated. In addition, the conventional clamp has a high failure rate and a high manufacturing cost.

More particularly, the present invention relates to a collet chuck for stably holding a cap so that the cap and the cap can be firmly coupled with each other, And to provide a cap pad with a sub motor and torque applied thereto.

Another object of the present invention is to provide a capping machine having a low failure rate and a low manufacturing cost.

In the present invention, by inserting air into the shaft shaft by the principle of the air chuck and pushing the chuck pusher,

The chuck shrinks by the slope so that the silicon pad attached to the chuck catches the cap;

A capping rotary sub motor for driving rotation of the chuck;

Motor connected to the capping rotation sub motor to sense a torque applied to the capping chuck by a container lid;

The control condition input device connected to the control unit is configured to operate according to the set value and the cap is coupled with the neck of the container to solve the problem.

Therefore, when the cap is bonded to the container, it is possible to firmly bind the cap, thereby reducing the defective rate and preventing damage to the appearance of the cap.

The present invention relates to a capping rotary sub motor which is connected to a capping rotary sub motor to detect a torque applied to the capping chuck by a container lid and to operate according to a set value set in a control condition input device connected to a control unit, The cap is bonded to the neck portion of the container at an appropriate rotational force to prevent damage to the outer surface of the cap, thereby further reducing the defective rate.

Figure 2: Caped collet chuck system and sub-motor and torque plan according to the invention

1, the capping device system according to the present embodiment includes a collet chuck system 11 and an air inlet system 12 as a power source for operating the collet chuck, And a connecting coupling 14 connecting the sub motor and the torque 13 with the collet chuck system 11 and the air inlet system 12 and the sub motor and the torque 13. The collet chuck system 11 has a chuck pusher 4 inside the chuck case 2 and a chuck pawl 6 in close contact with an inclined surface of the chuck pusher 4 and a chuck pawl 6 and a silicon pad 10 And a chuck-connecting PIN 8 for connecting the silicon pad case 7 provided with the chuck pin 7.

The air inlet system 12 is coupled to the camper body to form an air inlet for driving the inner chuck pusher 4 of the collet chuck system.

The sub motor and the torque (13) consist of a sub motor and a torque confirming the rotational force to lock the cap to the fixed tube container by rotating the cap.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 is a schematic view showing the state before the operation of the automatic capping device of the present invention, and FIG. 2 is a schematic view of the automatic capping device of FIG. 1 operated.

The collet chuck system 11 constructed as described above is brought into close contact with the chuck chuck 6 made of an inclined surface while advancing the chuck pusher 4 when the air is supplied through the air inlet system 12, And a contraction action is made to the central part. When the shrinking action is performed, the cap 1 is stably capped by the silicon pad 10 formed on the silicon pad case 7 coupled with the chuck pin 8.

Preferably, three or more capping chucks 6 having such a configuration are provided at regular intervals along the circumferential direction at the periphery of the cap 1. [

The capping collet chuck system 11 is movably coupled to the periphery of the shaft 5 and moves using an unillustrated actuator (such as a pneumatic cylinder) as a driving source. Here, an elastic member such as a coil spring 9 is provided so that the chuck pusher 4 can move without moving the chuck piece 6.

In this embodiment, when the collet chuck system 11 arrives at the cap clamping section, the capping bar movable portion moves and the chuck pusher 4 shrinks the chuck pawl 6, which is brought into close contact with the inclined surface, Is moved toward the cap 1, so that the cap 2 is clamped to the silicon pad 10.

As described above, the present invention can be applied to a method of fixing the container to the pressing means described in the manner in which the collet chuck system 11 is moved and the cap 1 is fixed to the container in a state where the cap 1 is clamped.

A capping slide mounted on the capping stage and being present at an upper portion of the capping position and capable of being moved left and right; and a capping mechanism disposed at an end of the capping slide, A capping rotary sub motor for driving the rotation of the capping chuck, and a control unit for controlling the rotation of the capping chuck, And a control condition input device connected to the control unit, wherein the collet chuck system (11) is connected to the capping chuck system (11) at a predetermined distance And then chucking is performed, and rotation is performed at the capping rotational speed inputted by the control condition input device And controls the capping rotating sub motor to stop the capping rotation when a torque generated from the container lid for the torque to be sensed reaches a predetermined torque value by the input through the control condition input device , The capping chuck releases the chucking of the container lid when the capping rotation is stopped, and the container clamping device releases the clamping to the container and takes out the capped container.

The present design preferably clamps the vessel by means of a plurality of silicon jaws attached to the end of the air cylinder. The chucking pressure is appropriately controlled by the air regulator to prevent damage to the container. The chucking of the capping chuck is controlled by the air regulator to an appropriate chucking pressure.

After the chucking is completed, the capping chuck is driven by the capping rotation drive servomotor 13 to perform the capping rotation.

The capping rotation drive servo motor 13 is connected to a torque. The torque senses the torque from the container lid during capping, and when the torque exceeds a predetermined value, the capping rotation drive servo motor is controlled to stop the capping rotation drive. Since the proper capping pressure is different for each vessel, the capping rotation is stopped when a properly set torque is detected in advance through the control condition input device. In this way, the capping pressure can be changed by adapting easily to various kinds of containers. When the capping rotation stops, the capping chuck releases the chucking and moves upward, and the container clamping device is controlled to release the clamping and take out the capped container.

In the present invention, the silicon pad 10 of the silicon pad case 7 connected to the chuck 6 is preferably made of urethane or silicone. If the pad is made of a material such as urethane or silicone, it is possible to prevent the capping device from damaging the body or the lid of the container even if the capping device malfunctions.
