Description

Can sealing machine {CAN SEAMING EQUIPMENT}

The present invention relates to a can sealer, and more particularly, to a driving device that operates a seaming chuck and a seaming roll in a can sealer that puts coffee, draft beer, carbonated beverage, etc. into a container and seals it.

In general, cans of various materials are used as packaging containers for various beverages such as coffee, draft beer, and carbonated beverages.

In the manufacture of such a can, a sealing technology to block the movement of air inside and outside the can after filling the inside of the can with beverage is the most important.

Here, when sealing a can filled with beverages, the opening of the can is covered with the can lid, and the can and the can lid are wound together and compressed to seal the can.

The operation of winding and compressing the can rim and the can lid rim is called a seaming operation, and most of this operation is performed by a manual or automatic can sealing machine.

For example, if a can with a can lid is placed on the lifting device of the can sealing machine and raised, the seaming chuck contacts the upper surface of the can lid and the can is fixed, and then the seaming chuck rotates rapidly. In the process of rotating the can, the surrounding seaming roll approaches the can side horizontally, and by applying pressure while continuously pushing the rim of the can lid toward the rim of the can, the opening of the can is closed by the lid of the can. This is sealed.

Usually, the seaming chuck and the seaming roll are operated by receiving power from the motor, and the motor power at this time is transmitted to the seaming chuck side and the seaming roll side by gear transmission or belt transmission.

As an example, Korean Patent Publication No. 10-2100566 discloses a method in which the power of the motor is transmitted to the seaming chuck side by belt transmission and the power of the motor is transmitted to the seaming roll side by gear transmission to operate the seaming chuck and the seaming roll. has been disclosed.

As another example, in Korean Patent Application Laid-Open No. 10-2015-0020761, a seaming chuck and a seaming roll in which the power of one motor is transmitted to the seaming chuck side by gear transmission and the power of the other motor is directly transmitted to the seaming roll side are operated. A way to do so is disclosed.

As another example, Korean Patent Application Laid-Open No. 10-2019-0098404 discloses a method in which power of a motor is sequentially transmitted to two connected gears to operate a seaming chuck and a seaming roll.

However, the methods disclosed in the above prior art documents have disadvantages in that they are difficult to manufacture and assemble and require a lot of manufacturing cost because their structure is complex and the number of parts is large, and the transmission efficiency is lowered due to the complicated power transmission step. .

On the other hand, in the automatic can sealing machine, the can lifting device is operated by the user's lever operation and serves to support the can, raise the can before seaming, and lower the can after seaming.

The existing lifting device has a disadvantage in that it takes a lot of force during operation because when the lever is rotated sideways, the can support block operated in connection with it has a structure in which it rises or descends while rotating in a spiral direction.

In other words, the weight of the beverage in the can and the weight of the block for the can jig supporting the can are added, which puts a lot of strain on the wrist when the lever is operated frequently. have.

In this state, when the user turns on the switch (not shown), the seaming chuck 13 and the seaming roll 14 are rotated by the operation of the motor 12, and eventually the rim of the can lid becomes the rim of the can. The can is sealed with seaming.

At this time, when the motor 12 is operated, the motor shaft 17 and the motor connection shaft 20 , the cam 15 , and the main gear 18 rotate together integrally, and in the main gear 18 , the seaming chuck gear The seaming chuck 13 is rotated by the power transmitted to (19). In addition, the power transmitted from the cam 15 leads to the seesaw motion of the side bar 16, and is Each of the installed seaming rolls 14 is alternately in contact with the seaming chuck 13, one by one, so that the seaming operation can be performed together with the seaming chuck 13.

Then, when the sealing operation for the can is completed, the motor 12 is stopped by turning the switch OFF, and then the can lifting device 11 is lowered through the lever operation to remove the can with the can lid sealed. The can seaming operation is completed by taking it out.

5 is a perspective view illustrating a can lifting device of an automatic can sealing machine according to an embodiment of the present invention, and FIG. 6 is a cross-sectional view illustrating a can lifting device of an automatic can sealing machine according to an embodiment of the present invention.

5 and 6, the can lifting device 11 automatically raises the can during can seaming and automatically lowers the can after seaming.

To this end, a lifting motor 32 is installed on one side of the lower plate of the can sealer body 10 , and a lifting device support 43 of a certain height is installed on the other side of the lower plate.

In addition, a transmission box 42 is installed on the bottom of the lower plate of the can sealer body 10, and a transmission means for transmitting motor power is installed inside the transmission box 42 at this time.

As an example, the electric means includes a driving pulley (not shown) mounted on the shaft of the elevating motor 32 and an electric pulley (not shown) mounted on the lower end of the electric shaft 41, and between the driving pulley and the electric pulley. It may be composed of a belt (not shown) connected to, and accordingly, the transmission shaft 41 can be rotated by the pulley and belt transmission when the elevating motor 32 is operated.

As another example, the electric means may be composed of a driving gear (not shown) mounted on the shaft of the elevating motor 32 and an electric gear (not shown) engaged with the driving gear while being mounted on the lower end of the transmission shaft 41. Accordingly, when the elevating motor 32 is operated, the transmission shaft 41 can be rotated by gear transmission.

In addition, a lifter cover 36 having a hollow cylindrical shape is installed on the upper surface of the lifting device support 43 , and a vertical key installation groove 38b is installed on the inner circumferential surface of the lifter cover 36 installed in this way.

A threaded portion is formed on the inner circumferential surface of the lifter 34 to enable screw transmission with the screw shaft 33 screwed thereto, and a vertical key installation groove 38a is formed on the outer circumferential surface of the lifter 34 to The lifter 34 can be guided in a straight line by the key 35 that is fitted into the key installation groove 38b of the lifter cover 36 at the same time.

Here, the bearing 39 is built in the upper end of the lifter 34, and the can block 40 supporting the can is placed on the upper end of the bearing 39 at this time, and accordingly, when the can is rotated It is possible to smoothly rotate together with the can while being supported by the bearing 39 of the can block 40 .

In addition, a screw shaft 33 coaxial with the lifter is installed inside the lifter 34 , and the lower end of the screw shaft 33 installed in this way is rotatable on the lower plate of the can sealer body 10 . It is coupled to the upper end of the transmission shaft 41 is installed.

Here, the screw shaft 33 , the lifter 34 and the lifter cover 36 are sequentially arranged from the inside to the outside to form a concentric circle, and at this time, the screw shaft 33 , the lifter 34 and the lifter cover 36 are ) coincides with the central axis of the seaming chuck 13 .

In particular, the can lifting device 11 includes a buffer spring 37 as a means to assist the initial lifting force when the lifter 34 is raised as well as a buffer action when the lifter 34 is lowered.

The buffer spring 37 is disposed around the screw shaft 33 , while the upper end supports the lower surface of the lifter 34 , and the lower end is installed to be supported by the lower plate of the can sealer body 10 .

Accordingly, when the lifter 34 is raised, the lifter 34 rises while receiving the restoring force exerted by the pressed buffer spring 37, so that the initial operation of the lifter 34 can be performed more smoothly. When descending, the shock is absorbed while the buffer spring 37 is pressed, so the shock at the completion of the descending of the lifter 34 can be reduced, and eventually the can can be stably descended without shaking.

(33), and then the lifter 34 rises by the screw transmission of the screw shaft 33 and the lifter 34, and at the same time, the cans and can lids placed on the can block 40 also rise. do.

Subsequently, when the can and the can lid reach the set height (eg, the height in contact with the sealing chuck), the operation of the elevating motor 32 is stopped and the can and the can lid thereon can also be maintained in an elevated position. there will be

Here, the method of stopping the operation of the elevating motor 32 after the completion of raising the can is a method commonly known in the art (eg, measuring the motor current to sense about 0.7A when normal, and then the can is sealed with the sealing chuck. When a load is applied while in contact with a method of detecting that the current rises to about 10A, etc.), it can be adopted without being particularly limited.

The can lid covered with the upper end of the raised can is positioned in the seaming work area, and the can is sealed while the can lid is seamed to the can by the operation of the seaming chuck and the seaming roll.

Next, after completing the sealing operation on the can, when a predetermined switch is operated DOWN, the elevating motor 32 reverses and the can descends, and in this state, the can is sealed with the can lid. By taking out the can seaming work is completed.

Even at this time, the method of stopping the operation of the elevating motor 32 after the can lowering is completed is not particularly limited and may be adopted as long as it is a method commonly known in the art (eg, a method of measuring a change in motor current, etc.).
