Description

Can seaming apparatus for food packaging

The present invention relates to a food packaging can seaming device, and more particularly, a plurality of seaming rolls whose number of installation is determined according to the shape of the can is linked to a plurality of cams by a single drive at different speeds. Packaging cans containing various foods by seaming while allowing a plurality of seaming rolls to be sequentially contacted and separated by the overlapping part of the can and the main body of the can being supplied on the can support which is raised and lowered while rotating. It is to maintain the sealed state more securely for a long time.

In general, metal cans are widely used as a means for long-term storage by sealing various foods in a vacuum state, and a separate can seaming device is used for sealing coupling between the lid and the body of these metal cans. There is a situation.

However, the conventional can seaming device for sealing coupling between the lid of the metal can and the edge of the main body as described above is simply wrapped around the edge of the lid and the opening edge of the main body so as to be sealed. In this case, since the sealing portion cannot maintain a perfect sealing state for a long time, external air penetrates into the can through the sealing portion, and the contents contained in the can are deteriorated. During the sealing operation of the filled cans, there was a problem that, due to the occurrence of a poorly packaged product, which is not completely sealed, the economic loss of disposing of the can and the contents together with the can was taken.

Accordingly, an object of the present invention is to solve the problems of the conventional food packaging cans, which are rolled in a state in which the lid of the food packaging can and the edge of the main body are simply overlapped to be sealed as described above. The support rolls provided on the upper ends of the eccentric support shafts on which the seaming rolls are installed are rotated at different rotational speeds from the cam members by a single driving source in a state in which the positions thereof are variable by the multi-stage cam members. As the position is changed by the seam, the sealing of the food packaging can is sequentially folded in the overlapping state while the seaming roll is rotated, and then a series of sealing operations are finally pressed in the state only by winding the folded seal again. It is easy to make by the process of perfect packaging of various foods By neunghage so as to be able to talk to a cost reduction by lowering the percentage of defective cans for food packaging as much to maintain a perfect seal over a long period of time to provide a food packaging cans seaming apparatus for packaging food cans.

In addition, the number of installation of the cam member 42, the eccentric support shaft 51, the support roll 53 and the seaming roll 55 is determined according to the shape of the can can be used for seaming, the shape of the can is triangular If each of the three or each of the four squares are installed, this example will be described as an example of the seaming operation of a rectangular can, a typical ham packaging container.

A description will be given of an implementation operation state of the food packaging can seaming device A according to the present invention having the above configuration.

Open the opening / closing window 12 on the front surface of the vacuum chamber 11 of the main body 1, and put it on the can base 71 of the support 7 with the cover on the opening of the main body of the can requiring seaming. When the can seaming device A of the present invention is operated while the opening and closing window 12 is closed, the vacuum and seaming operations for the can 10 may be performed as the vacuum means 8 and the driving means 9 operate together. This is done.

First, according to the operation of the vacuum means 8, the air inside the vacuum chamber 11, that is, the air inside the can, is sucked out and discharged to the outside through the hose 81 to vacuum the inside of the vacuum chamber 11 including the inside of the can 10. To be maintained.

At the same time, the drive shaft 1 receives the rotational force of the drive means 9 by the drive pulley 24 according to the drive of the drive means 9 composed of the drive motor and the reducer.

At this time, the rotational force of the drive shaft 1 is transmitted to the rotation shaft 6 by the worm 23 and the worm gear 61 and simultaneously transmitted to the first and second drive helical gears 21 and 22 at the tip of the drive shaft 1. Thus, the first and second operating helical gears 41 and 52 engaged with each other are rotated.

When the rotary shaft 6 is rotated in this way, as the rotary cam member 62 installed at the lower end of the rotary shaft 6 rotates, the connecting rod having the operating roll 63a of the tip contacted the rotary cam member 62 ( 63 is a seesaw operation with the pivot axis 64 in the middle by the rotary cam 62a to raise and lower the can support 7 connected to one end thereof. (7) The can to be seamed by the lid and the main body placed on the upper can holder 71 is raised so that the lid is brought into close contact with the support die 31 at the lower end of the main shaft 3.

The can 10 is raised by the upward movement of the can support 7 and the cam shaft 4 and the operating shaft 5-1 connected to the first and second operating helical gears 41 and 52 are mutually different. The cam shaft 4 is rotated more slowly than the operating shaft 5-1. At this time, the cam shaft 4 is rotated more slowly than the operating shaft 5-1. The cam member 42 installed in multiple stages on the outer surface of the cam shaft 4 is slowly rotated and operated. The operating plate 5 connected to the lower end of the shaft 5-1 is in a state of being rotated slightly faster than the cam member 42.

The position of the multi-stage cam member 42 is pushed by the cam 42a in the state in which the support roll 53 of the upper end of the eccentric support shaft 51 is in contact with each other. The shimming roll 55 connected by the base 56 is rotated to the can side by the operating table 56 being rotated about the eccentric support shaft 51 to be in close contact with the sealing overlap between the lid and the main body edge. Press seaming to the sealing overlap portion is made until the support roll 53 in contact with the cam 42 in advance in the state off the cam 42.

Such a series of seaming operations are performed by the spring 51a on the eccentric support shaft 51 on the top of the cam member 42, which is to be formed on the outer surface of the cam member 42 which is installed in multiple stages on the outer surface of the cam shaft 4. Since the order in which the support rolls 53 are always supported in a shot state is changed, the seaming rolls 55 at the bottom of the eccentric support shaft 51 are differently contacted with the sealing part of the can 10 at different intervals. Since the seaming operation is performed in such a way that the sealing seaming portion of the can 10 is momentarily folded between the edge portion of the support die 31 and the edge portion of the seaming roll 55, the sealing seaming portion undergoes a process of being pressed again in a dried state. As a result, the cover edge and the edge of the opening of the main body are surely seamed in an overlapped state, so that the seaming work is completed as a finished product.

Simming work is completed by the plurality of seaming rolls 55, and at the same time the position of the rotary cam 62a of the rotary cam member 62 is changed, the operation roll 63a of one end of the connecting rod 63 is rotated by the rotary cam 62a. As it rises away from it, the other end of the connecting rod 63 is lowered about the pivot shaft 64 so that the can support 7 is lowered and the vacuum means 8 and the driving means 9 stop their operation. do.

Thereafter, the operator opens and closes the opening / closing window 12 in front of the vacuum chamber 11 and lifts the can 10 which is seaming completed from the can holder 71, and cans which are covered with a cover to another body requiring seaming. When the device A is operated while the opening and closing window 12 is closed by placing it on the base, the above-described series of seaming operations are smoothly performed to obtain a food packaging can having a desired seaming operation.

In the above configuration, the shape of the seaming target can is described as being rectangular in this example. However, the shape of the seaming can is not necessarily specified and may be applied to, for example, a triangular or circular food packaging can.

As described above, although the present invention has been described in the above embodiments, it is not necessarily limited thereto, and various modifications may be made without departing from the scope and spirit of the present invention.

As apparent from the above description, according to the food packaging can seaming apparatus of the present invention, a plurality of seaming rolls can be contacted or separated to the can side by a single driving source, so that the operation can be sequentially and stepwise. Fold the cover of the can of food packaging cans with a specific shape and the sealing part of the body edge in a superimposed state, so that a series of seaming operations can be quickly and easily performed in a single process to prevent defects in the food packaging process using the can. Prevents the deterioration of the contents by providing a long time to maintain a complete seal state.
