Republic of Korea Utility Model Registration No. 0378218, Republic of Korea Registration Utility Model No. 0389428

The present invention relates to a sealing device, and more particularly to a simpler device configuration, it is possible to adequately degas the inside of the package containing the contents to seal the package, as well as to quickly transfer the finished package. It relates to a sealing device provided with a worktable.

The sealing device is a device for sealing one surface opened by heat fusion or the like in a state where the contents are accommodated inside the wrapper in order to keep the contents such as food and the like for a long time in a fresh state. Such a sealing device has been proposed to have a function of sealing the inside of the wrapping paper in a vacuum state so that the taste and aroma of the contents can be stored for a longer time, away from the device that simply sealed the wrapping paper. Utility Model No. 0378218 and Republic of Korea Utility Model No. 0389428 are examples of such techniques.

The above techniques are basically additionally equipped with vacuum means including a suction nozzle which slides back and forth to the sealing device to vacuum the inside of the wrapping paper, and a vacuum pump and control means for vacuuming the inside of the wrapping paper. There is a technical feature in that. This technical feature is an additional device adopted by most of the proposed technologies rather than the original technical configuration of the above technologies, and at first glance, the contents can be stably stored in a long time because the inside of the wrapping paper can be made closer to a vacuum state. The benefits are expected, but there are a few problems:

First, a high-power vacuum pump is basically required to make the interior of the package close to vacuum rather than simply degassing. In addition, the precise configuration of the suction nozzle itself inserted into the package and the driving means of the suction nozzle, and such a device Control means for precisely controlling them are required. However, in order to configure such devices, the unit price of the sealing device is inevitably increased, and when the inner state of the sealed package needs to be kept close to a vacuum, food such as vegetables and fish is very important. Considering the reality that only the case of accommodating, there is a problem that the burden on the purchase cost of the device is too high for the user of the sealing device.

In addition, most of the sealing devices employing the above-described techniques are used for vacuuming and sealing the wrapping paper, and in the state where the wrapping paper containing the contents is placed at an arbitrary position on the work table, the vacuum nozzle is advanced to move the inside of the wrapping paper. After the vacuum operation is performed by inserting it into position, the process of reversing the vacuum nozzle to completely remove the vacuum nozzle from the inside of the wrapping paper or sealing the open end of the wrapping paper while the end of the vacuum nozzle is back to the vicinity of the opening end of the wrapping paper is performed. Going through.

In other words, in order to vacuum by the conventional sealing device, the vacuum nozzle must repeat the forward and backward movements at regular time intervals. It is pointed out as an important disadvantage in that an increase in working time leads directly to a decrease in productivity in a sealing device whose main purpose is mass production.

Furthermore, as disclosed in the drawings of Korean Utility Model Registration No. 0378218 and Korean Utility Model Registration No. 0389428, these devices are designed to block air entering the opening end of the package by a vacuum nozzle inserted into the package. Since the sealing operation is performed while the opening end is pushed into the sealing device as much as possible, it is not sealed at the opening end of the wrapping paper, but instead of sealing the portion away from the opening end inside the wrapping paper containing the contents. Getting drunk.

As such, when the sealed portion of the sealed wrapping paper is not formed at the opening end but is formed at a predetermined distance away from the end, the foreign matter is caught in the unsealed end during distribution. There is a problem with hygiene, but consumers are reluctant to buy. In order to improve this point, additional cutting work to remove the end of the unsealed unnecessary wrapping paper should be performed, and the additional work will increase the manufacturing cost of the wrapping paper as the productivity of the sealing device will eventually decrease. There is a disadvantage.

The present invention has been proposed to solve the above problems, to provide a sealing device that can perform the degassing operation and the sealing operation at the same time to fix the contents contained in the wrapping paper in a more easily added configuration with a simpler configuration The purpose is.

Another object of the present invention is to provide a sealing device capable of appropriately performing a degassing operation and a sealing operation irrespective of the size of the wrapping paper.
