Can seaming apparatus for food packaging

The present invention relates to a food packaging can seaming device, and more particularly, three seaming rolls are supplied to a lifter plate which is lifted and lowered while rotating at different speeds in conjunction with a plurality of cams by a single driving source. By the overlapping part of the cover of the can and the main body, the seaming can be made while the plurality of seaming rolls are sequentially contacted and separated, so that the sealed state of the packaging can containing various food contents can be more reliably maintained for a long time. It would be.

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 simply rolls the edge of the lid and the edge of the opening of the main body in an overlapping state and presses the seal in two stages. 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. In addition, due to the occurrence of a poorly packaged product that is not completely sealed during the sealing operation of the can filled with the contents, there was a problem such as the economic loss that must be disposed of together with the contents of the can.

Accordingly, an object of the present invention is to solve the various problems of the conventional food packaging cans by simply rolling the cover and the edge portion of the main body of the food packaging cans simply overlapped to form a seal. The shimming cam rolls installed on the top of the shimming roll lever shafts on which the shimming rolls are installed are rotated at a different rotation speed from the shimming cam members by a single driving source while the mining rolls are variable in position by the multi-stage shimming cam members. The position of the cam member is changed by the cam of the cam member, so that the lid and the main edge of the can for food packaging can be sequentially folded in a state where the seaming roll is rotated, and then the folded seal is rolled up again to finally press in the state. Content of three stages of sealing By enabling the perfect packaging of various foods, it is possible to reduce cost by reducing the defective rate of food packaging cans, and to maintain the perfect sealing state for a long time, thus providing food packaging can seaming device for canned foods. Is in.

In this example, the seaming operation of a rectangular can, which is a general ham packaging container, will be described as an example.

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.

On the can lifter plate 71 of the can lifter shaft 7 in a state where the opening and closing window 12 on the front surface of the vacuum chamber 11 of the main body 1 is opened and the lid is covered on the opening of the main body of the can requiring seaming. When the can seaming device A of the present invention is operated with the opening and closing window 12 closed, the vacuum means for the can 10 is operated as the vacuum means 8 and the driving means 9 are operated together. And seaming is performed.

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 2 receives the rotational force of the drive means 9 by the drive pulley 24 in accordance with the drive of the drive means 9 composed of the drive motor and the reducer is rotated.

At this time, the rotational force of the drive shaft 2 is transmitted to the vertical shaft 6 by the worm 23 and the worm gear 61, and at the same time the seaming cam drive helical gear 21 and the seaming head drive helical gear 22 at the tip of the drive shaft 2. It is delivered to the) and is engaged with the shimming cam operation helical gear 41 and the seaming head operation helical gear 52 is engaged with it.

When the vertical shaft 6 is rotated in this way, as the lifter cam 62a installed at the lower end of the vertical shaft 6 rotates, the lifter lever in which the lifter cam roll 63a of the tip is in contact with the lifter cam member 62 ( As the seesaw operation is performed by the lifter cam 62a about the lifter lever shaft 64 in the middle thereof, the lifter cam 62a raises and lowers the canlifter shaft 7 connected to one end thereof. The can to be seamed by the lid and the main body placed on the can lifter plate 71 on the top of the canlifter shaft 7 is raised so that the lid is brought into close contact with the chuck 31 at the bottom of the spindle 3.

In this manner, the can 10 is lifted by the ascending operation of the canlifter shaft 7, and at the same time, the seaming cam rotary gear 4 and the seaming head connected to the seaming cam operated helical gear 41 and the seaming head operated helical gear 52 are provided. The shaft 5-1 is rotated at different rotational speeds. At this time, the seaming cam rotary gear 4 is rotated more slowly than the seaming head shaft 5-1, which is the outer surface of the seaming cam rotary gear 4. The shimming cam member 42 installed in multiple stages is rotated slowly and the shimming head 5 connected to the bottom of the shimming head shaft 5-1 is rotated a little faster than the shimming cam member 42.

The position of the seaming cam member 42 is pushed by the seaming cam 42a while the seaming cam roll 53 on the top of the seaming roll lever shaft 51 is in contact with the seaming roll lever shaft 51. The seaming roll 55 connected to the bottom by the seaming roll lever 56 is rotated to the can side by the seaming roll lever 56 being rotated about the seaming roll lever shaft 51 so that the cover and the edge of the main body Pressing seaming on the sealing overlapping portion is performed until the seaming cam roll 53 which is in contact with the seaming cam 42 in the state close to the sealing overlapping portion is removed from the seaming cam 42.

Such a series of seaming operations are carried out on the top of the seaming roll lever 51 according to the formation position of the seaming cam 42a to be formed on the outside of the seaming cam member 42 which is installed in multiple stages on the outside of the seaming cam rotary gear 4. Since the order in which the seaming cam rolls 53 are always supported by the spring 51a to be pushed out is changed, the seaming rolls 55 at the bottom of the seaming roll lever 51 are different from each other at regular intervals. Since the seaming operation is performed in such a manner that the sealing portion of 10 may be contacted, the sealed seaming portion of the can 10 is temporarily folded and rolled between the edge portion of the chuck 31 and the edge portion of the seaming roll 55. As the process is pressed again, the edge of the cover and the edge of the opening of the main body are seamed in a superimposed state, and the seaming work is completed as a finished product.

As the seaming operation is completed by the plurality of seaming rolls 55 and the position of the lifter cam 62a of the lifter cam member 62 is changed, the lifter cam roll 63a of one end of the lifter lever 63 is lifter cam 62a. The other end of the lifter lever 63 is lowered again with respect to the lifter shaft 64 as the lifter 63 is lowered, and the vacuum means 8 and the driving means 9 are simultaneously lowered. It will stop working.

Thereafter, the operator opens the opening / closing window 12 on the front side of the vacuum chamber 11, lifts the can 10 which is in the state of seaming from the can lifter plate 71, and opens the can which is covered with another body in which seaming is required. When the device A is operated while the opening / closing window 12 is closed while being placed on the can holder, the above-described series of seaming operations are performed smoothly, thereby obtaining a food packaging can having a desired seaming operation. In the above configuration, the shape of the seaming 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. (42), the eccentric support shaft 51, the support roll 53, and three seaming rolls 55 are provided. In this case, four or five seaming rolls 55 may be provided. The three seaming rolls 55 have different depths of the edge portion, and the first seaming roll 55 has a deeper edge portion, and the other two stages. The seaming rolls 55 and the three-stage seaming rolls 55 are formed to have an increasingly shallow depth of the edge portion. The conventional seamer is composed of the first roll and the second roll, and the edge of the first roll is slightly narrow and deep, The edge of the burn roll is slightly wider and shallower. The shimmer is a two-roll system seam in which the can and the lifter rotate together while the chuck rotates according to the shape, and a four roll in which the seaming head rotates while the can is stopped without the chuck rotating. There is a system shimmer, which is an improvement on the latter four-roll system head. The seaming rolls are driven together according to the rotational force of the chuck rotation or the rotation of the seaming head. Curl (C url) is rolled up to the edge portion of the seaming roll. The first stage seaming roll 55 passes through the chuck along the curve of the cam. The seaming roll 55 also performs the same operations as the seaming rolls of the first and second stages, in which the three-stage seaming rolls flatten the slightly rounded state made by the two-stage seaming rolls so that the air inside the can is not circulated. In other words, when seaming food cans using three seaming rolls 55, the first stage seaming rolls 55 of the edges of the seaming rolls 55 abutting the edge portions of the support die 31 are maintained. ) Deeply forms the edge portion to first seam, and then forms the depth of the edge portion of the next two or three seaming rolls 55 in order, thereby reducing wrinkles or overlapping portions generated at the edges of the can during seaming. It is possible to prevent the bad seaming.

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 device of the present invention, the three seaming rolls can be contacted or separated to the can side by the single drive source in a sequential and stepwise manner. 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.
