Description

Automatic food container packaging device {Packer for portable bowl}

The present invention relates to a food container packaging device. More specifically, the process of sealing the film at the open top of the food container by heat fusion is automatically performed, and the film is sealed according to the size of the open top of the food container. This relates to an automatic food container packaging device that greatly improves user convenience by preventing unnecessary waste of film and easily removing excess film to retrieve the film unwound from the film roll.

Recently, as the demand for delivery and packaged food has rapidly increased, various packaging containers for food packaging, especially disposable food containers, have been widely used.

At this time, to prevent leakage or deterioration of the packaged food, it is mainly used in disposable food container packaging and includes a tray sealer and a vacuum pouch sealer.

Among these, the container sealing device is mainly used to seal and package liquid foods, including soups, and fragile foods in disposable containers, and the vacuum pouch sealing device is a pouch that allows meat, such as beef milk, to be stored in a vacuum for a long time. It is mainly used to seal and package food ingredients in a vacuum.

Here, the container packaging device is a device that prevents food from leaking by heating and fusing a thermoplastic film to the edge of the opening (entrance) of a disposable container, and various films are used.

Conventionally, films using PVC or polypropylene as the main material are widely used, but in the case of PVC, additives such as fillers, plasticizers, and stabilizers are added during the processing process, and these added additives are harmful to the human body, making it difficult to use. Due to the current situation, polypropylene films, which have excellent properties such as heat resistance, tensile strength, and bursting strength, are widely used.

Recently, in addition to manual food container packaging devices that allow users, such as restaurant workers, to place a container containing food, place a film on it, and then apply direct pressure to seal it, when a container containing food is placed, it automatically seals the container. Automatic food container packaging devices that seal the film at the top opening while operating are also becoming widely available.

Among these, the conventional automatic food container packaging device is designed to tightly seal and pack the film released from the film roll without causing wrinkles, etc., by opening the top of the container containing the food, that is, at a certain distance forward, left, and right beyond the rim of the container. A film with enough leeway is used.

That is, after covering the top opening of the container with a film having a width larger than the left and right widths of the container's rim, the excess film around the rim of the container is pressed to maintain tension without wrinkles, As a heating member, it is pressurized and sealed, and then the front and rear ends are cut to complete packaging.

Therefore, when the top opening of a food container is wrapped with a film using a conventional automatic food container packaging device, as shown in Figure 1, extra film is present around the edge of the food container on the front, left, and right sides. As a result, the excessive use of unnecessary films not only increases packaging costs, but also becomes a major cause of environmental pollution due to disposal.

In addition, in a conventional automatic food container packaging device, when a food container containing food is introduced into the packaging device to seal the top opening of the food container with a film, the film released from the film roll is placed on the upper side of the top opening of the food container. It is pulled out so that it is positioned, and at this time, for holding according to the withdrawal, the spare film is released at a certain interval as shown in FIG. 2.

Accordingly, when a container containing food is introduced into the packaging device, the above-mentioned excess film is present at the tip of the film, so that after sealed packaging and cutting, the excess film is as shown in FIG. 1. In the cut state, it remains inside the packaging device.

Accordingly, in the past, there was the inconvenience of users having to separately collect and dispose of the excess film accumulated inside the packaging device, and in some cases, the cut excess film remained within the packaging device body and became stuck in various parts, causing malfunction. Of course, there was a problem that could cause a malfunction.

FIG. 4 is a plan view of the food container tray 140 in FIG. 3, and FIG. 5 is a configuration diagram of the food container tray 140 in FIG. 3 when it is inserted into the main body of the packaging device.

As shown in FIG. 4, the food container tray 140 is slidably moved in the forward and backward directions along the guide member 112 installed in the main body 110 by a control signal, and is seated for insertion of the body of the food container. It includes a moving plate (not shown) in which a hole is formed, and a sealing member 150 that is installed to protrude at a certain height around the seating hole of the moving plate and on which the edge portion 12 of the food container is seated and mounted. It may be composed of:

Here, the sealing member 150 may be made of a silicone material that has a certain elasticity and excellent heat resistance.

In addition, the food container tray 140 may be configured to further include film supports 160, 170, 180, and 182 formed at a certain height on the rear and front ends of the sealing member 150, respectively.

That is, the film support part includes a first support part 160 installed laterally on a plane at a certain distance from the rear end of the sealing member 150 installed around the seating hole of the moving plate, and this first support part 160. It may be configured to include a second support portion 170 installed on both sides of each end between the rear end of the sealing member 150 and the rear end of the sealing member 150.

Here, a portion of the second support portion 170 may be located on the same line as the rear end of the sealing member 150 to a certain extent.

In addition, the film support part includes a third support part 180 installed laterally on a plane at a predetermined distance from the tip of the sealing member 150 installed around the seating hole of the moving plate, and this third support part 180 It may be configured to further include a fourth support portion 182 formed to extend from both side ends toward the sealing member 150.

Here, a portion of the fourth support portion may be located on the same line as the tip of the sealing member 150 to a certain extent.

At this time, other parts of the second support part 170 and the fourth support part 182 may be partially positioned on the same line as both side ends of the sealing member 150.

It is preferable that such a film support part is made of a material having a certain elasticity.

Meanwhile, the end of the film 22 unwound from the film roll 20 is inserted and fixed at the front end of the moving plate, that is, at a position spaced apart from the front end of the sealing member 150 and the third support portion 180 by a certain distance. A film fixing part (A) may be formed for.

Here, the film fixing part (A) may be a groove into which the end of the film 22 is inserted.

Therefore, when the door 130 is closed with respect to the main body 110, the guide piece 132 of the door 130 presses the end of the film 22 and pushes it toward the film fixing portion A of the moving plate, The end of the film 22 is fixed by the film fixing portion (A) of the moving plate, so that when the food container tray 140 slides inside the main body 110 along the guide member 112, it is linked to FIG. 5 As shown, as it enters the main body 110, it is located above the top opening of the food container 10.

The operational relationship resulting from this will be explained in detail later.

Figure 6 is a bottom view of the pressurizing and heating member 200 in the automatic food container packaging device according to an embodiment of the present invention, Figure 7 is a side view of Figure 6, and Figure 8 is a front view of Figure 6.

In addition, Figure 9 is an enlarged front view of one of the cutting members provided in the automatic food container packaging device according to an embodiment of the present invention.

In addition, Figure 10 is a configuration diagram of the state in which the pressurizing and heating member 200 in Figure 5 operates to seal the film at the top opening of the food container, and Figure 11 shows the food packaged with the film sealed at the top opening in Figure 10. It is a configuration diagram of a state in which the container is pulled out, and FIG. 12 is a plan view of a food container packaged with a film sealed at the top opening by an automatic food container packaging device according to an embodiment of the present invention, and FIG. 13 is a perspective view of FIG. 12. am.

First, referring to FIGS. 6 to 8, the pressing and heating member 200 includes a cam member 114 that rotates by a certain angle in response to a control signal, and a base that is raised and lowered according to the rotation of the cam member 114. It may be configured to include a plate 210, a heating plate 220 in which the base plate 210 and each corner are spaced apart from each other by an elastic support bar 212 and a heater is installed.

In addition, the pressing and heating member 200 includes a pair of first pressing rods 230 that are installed to protrude downward by a certain length on both sides of the rear end of the base plate 210 and have elasticity, and the first pressing rod 230. It may be installed on both sides between the rod 230 and the rear end of the heating plate 220 to protrude downward by a certain length and further include a pair of second pressure rods 240, which are also elastic. .

In addition, the pressing and heating member 200 includes a pair of third pressing rods 250 that are installed to protrude downward by a certain length on both sides of the distal end of the base plate 210 and have elasticity, and this third pressing rod 250 It may be configured to further include a pair of fourth pressing rods 260, which are installed to protrude downward by a certain length on both sides between the tip of the rod 250 and the heating plate 220 and are also elastic. .

Therefore, when the pressing and heating member 200 descends and the heating plate 220 pressurizes the film and seals it to the edge portion 12 of the food container by heat fusion, the end of the first pressing rod 230 is attached to the food container. Both side ends of the film 22 are held in close contact with the first support part 160 of the container tray 140, and the ends of the second pressure bar 240 are attached to the second support part 170 of the food container tray 140. As it comes into close contact with, both side ends of the film 22 are held.

In addition, the end of the third pressure rod 250 is in close contact with the third support portion 180 of the food container tray 140 and holds both side ends of the film 22, and the end of the fourth pressure rod 260 is As it comes into close contact with the fourth support portion 182 of the food container tray 140, both side ends of the film 22 are held.

Meanwhile, the pressing and heating member 200 descends and when the heating plate 220 pressurizes the film 22 and seals it to the edge portion 12 of the food container 10 by heat fusion, the film 22 simultaneously ) can be installed with cutting members (300, 310) for cutting the front and rear ends.

This cutting member is installed to protrude downward from the rear end side of the base plate 210 by a certain length, and is a first cutter installed in the horizontal direction between the first pressure bar 230 and the second pressure bar 240. (300), and a second cutter that is installed to protrude downward by a certain length from the tip side of the base plate 210 and is installed in the horizontal direction between the third pressure bar 250 and the fourth pressure bar 260. It may be composed of a configuration including (310).

At this time, teeth 312 are formed at regular intervals at the end of the second cutter 310, but as shown in FIG. 9, a portion of the middle end is toothless where the teeth 312 are not formed at regular intervals. It may be formed as part 314.

Therefore, when the second cutting machine 310 cuts the film, the entire spare film 22b is not cut, but cutting is performed with a portion of the film 22b connected. The operating relationship will be described in detail later.

Meanwhile, when the pressing and heating member 200 descends and the heating plate 220 presses the film and seals it to the edge 12 of the food container by heat fusion, the first pressing rod 230 is connected to the film roll ( Both ends of the film 22 connected to 20 are supported, and the second pressure bar 240 supports both rear ends of the film 22 sealed at the top opening of the food container 10, The third pressure bar 250 supports both sides of the spare film 22b, and the fourth pressure bar 260 supports both sides of the tip of the film 22 sealed at the upper opening of the food container 10. I do it.

Accordingly, the film 22 for sealing the upper opening of the food container 10 is stretched tightly by the first pressure rod 230 to the fourth pressure rod 260 and is sealed without wrinkles. This is achieved, and accordingly, cutting of both ends by the first cutter 300 and the second cutter 310 can be easily performed.

In particular, as described above, the second support portion 170 corresponding to the same vertical line as the second pressing rod 240 and the fourth support portion 182 corresponding to the same vertical line as the fourth pressing rod 260 The rear end and both side ends of the sealing member 150, as well as the front end and both side ends, and part thereof are located on the same horizontal line, so that even if a film whose width matches the width of both side ends of the food container is provided, pressing and sealing by heat fusion is possible. And when holding for this purpose, the film 22 can be held stably.

Therefore, as in the past, a film having a width greater than the width of both side ends of the food container 10 to be sealed is not necessarily provided, but a film having a width corresponding to the width of both side ends of the food container 10 to be sealed is provided. Even if provided, it is possible to package the film in a stable and sealed manner, thereby reducing the cost of packaging by preventing the waste of unnecessary film, and also reducing the amount of discarded film, ultimately reducing the cause of environmental pollution. .

In addition, the first cutter 300 and the second cutter 310 can be placed adjacent to the front edge and the rear edge of the food container 10 to be packaged, so that the food container 10 By being able to cut the front edge and the rear edge without leaving much excess film, it is also possible to prevent unnecessary waste of film.

In addition, when sealing the film by thermal fusion and simultaneously cutting both side ends of the film 22 using the first cutter 300 and the second cutter 310, a spare film ( When the second cutter 310 cuts 22b), the excess film 22b is not cut so as to be completely removed from the film sealed in the food container due to the non-toothed portion 314, and as shown in Figures 12 and 13 As shown, by cutting in a connected state by a connection part of a certain width, the operator can easily remove it from the container in which packaging has been completed, which not only increases the convenience of packaging work, but also increases the packaging device 100. The effect of eliminating the cause of failure can also be provided.

The operational relationship of sealingly packaging a film at the top opening of a food container using the automatic food container packaging device 100, which can be configured as described above, is briefly explained as follows.

First, as shown in FIG. 3, the film roll 20 is seated on the roll seating part 120, and the end of the film wound around the film roll 20 is attached to the film fixing part A of the food container tray 140. After positioning and closing the door 130 to fix the end of the film, place the food container to be packaged in the seating hole of the food container tray 140 while discharging the food container tray 140 from the main body 110. I order it.

Of course, in this case, the heater built into the heating plate 220 of the pressurizing and heating member 200 is heated to the set temperature.

In this state, when the operator operates the operation switch installed on the door 130, the food container tray 140 slides into the main body 110 along the guide member 112 as shown in FIG. 5. do.

At this time, as the food container tray 140 slides, the end of the film wound on the film roll 20 also moves inside the main body 110, and accordingly, the film roll 20 rotates and spreads the film to a certain length. By releasing it as much as possible, a part of the film is located above the top opening of the food container to be sealed and packaged.

In this way, when the insertion of the food container tray 140 into the main body 110 is completed, the pressurizing and heating member 200 is lowered by the rotation of the cam member 114 by the control signal, thereby heat-sealing the film to the food. In addition to pressurizing and sealing the rim 12 of the container, the front and rear ends of the rim 12 of the food container are cut using a cutting member.

Since this sealing process and cutting process have been previously described, repeated explanations thereof will be omitted.

When sealing, packaging, and cutting by the pressing and heating member 200 are completed, the pressing and heating member 200 rises again by rotation of the cam member 114, and the food container tray 140 is shown in FIG. 11. As is done, it comes out of the main body 110, and at this time, the upper opening of the food container is packaged in a sealed state with a film.

However, the extra film 22b is not completely cut by the non-toothed portion 314 of the second cutting machine 310, but is connected by some connections, so the worker holds the extra film 22b. Just pull it to separate it.

As described above, according to the automatic food container packaging device 100 according to an embodiment of the present invention, the film released from the film roll 20 is firmly pressed at the front and rear ends to seal tightly without wrinkles, By packaging, even if a film with a width corresponding to the left and right widths of the food container 10 is used, the packaging is tightly sealed without fear of leakage, thereby preventing unnecessary waste of film, reducing packaging costs, and also. This can have the effect of reducing the amount of discarded film and ultimately reducing the cause of environmental pollution.

In addition, according to the automatic food container packaging device 100 according to an embodiment of the present invention, the excess film 22b is cut at regular intervals to smoothly remove the film 22 released from the film roll 20.
