Referring to these drawings, the food container packaging device of the present embodiment seals the upper surface of the food container 115 with a film, but the problem remaining in the top of the food container 115, including the problem of poor operation due to the film curled up as conventional In order to efficiently solve the inconvenience of the removal operation, the device body 110, the tray 120, the upper roller 130, the lower roller 140, and the lifting and lowering / cutting unit 160 do.

The device body 110 is a part forming the exterior of the device, and supports the tray 120, the upper roller 130, the lower roller 140, and the lifting / lowering / cutting unit 160 for each location.

One side of the apparatus body 110 is rotatably coupled to the film roll 150 is wound around the film to be sealed in the food container (115).

The film released from the film roll 150 is automatically discharged through the lower roller 140 while being tensioned by the plurality of film guide rollers 151 and 152.

At this time, the discharge film discharged as shown in the enlarged picture in Figure 1 is cut by the cutting blade 162 to be described later to cover the upper portion of the food container 115, the area of the portion to be sealed in the through hole (H) form Has

The tray 120 supports the food container 115. The tray 120 is a device body 110 to move between the food container loading / unloading position where the food container 115 is loaded or unloaded, and the film sealing operation position where the film is sealed in the food container 115. It is provided to be movable.

Referring to FIG. 1, the inside of the apparatus body 110, that is, the lower region of the elevating sealing / cutting unit 160 is the film sealing operation position and the outer side is the food container loading / unloading position.

In the food container loading / unloading position, the food container 115 to be sealed is loaded into the tray 120 or the food container 115 which has been sealed is unloaded from the tray 120.

The tray 120 is provided with a plurality of spring plungers 170 for elastically supporting the food container 115. The plurality of spring plungers 170 including the springs 171 elastically support the upper flanges 115a of the food containers 115 at the bottom in four circumferences of the food containers 115 as shown in FIG. 2.

For reference, in order to easily remove the food container 115 from the tray 120, that is, to apply an unloading container support plate or a separate lifting motor may be considered, but in this case, it is necessary to have a frequent sensor There is a disadvantage.

However, when the spring plungers 170 of the mechanical structure are disposed in the tray 120 region as in the present embodiment, the spring 171 is lowered as much as the spring 171 is pressed during the sealing operation by the elevating sealing / cutting unit 160. When the operation is completed, the spring 171 is expanded, so that the food container 115 can be raised to an easy position to take out, and thus there is an advantage that it can be easily used without failure.

Therefore, as in the prior art, the container support plate, the lift, the article detection sensor or the lifting motor is not required at all, and the failure rate can be significantly reduced.

The tray 120 and the elevating sealing / cutting unit 160 are provided with friction teeth 128 and 168 for holding the film during the sealing operation for the food container 115.

In addition, the tray 120 is formed with a cutting blade passage slit 122 through which the cutting blade 162 passes during the sealing operation for the food container 115. The cutting blade passage slit 122 may be positioned to correspond to the position of the cutting blade 162 in the form of a groove.

The upper roller 130 is rotated in conjunction with the movement of the tray 120 when the tray 120 is moved from the food container loading / unloading position to the film sealing operation position.

The rack gear 125 is coupled to the upper rear side of the tray 120 so that the upper roller 130 and the tray 120 can interact with each other, and a rotation axis of the upper roller 130 is formed inside the upper roller 130. An upper roller shaft 131 connected to the gear 125 is provided.

At this time, between the upper roller shaft 131 and the upper roller 130, the one-way clutch for transmitting the rotational force of the upper roller shaft 131 to the upper roller 130 only when the tray 120 is drawn into the film sealing operation position ( one way clutch 132 is provided.

In other words, the rotational force of the upper roller shaft 131 due to the one-way clutch 132 is transferred to the upper roller 130 only when the tray 120 is pulled from the food container loading / unloading position to the film sealing operation position so that the upper portion is rotated. The friction force of the roller 130 and the lower roller 140 allows the film to be transferred to the film sealing operation position.

However, when the tray 120 is withdrawn from the film sealing operation position to the food container loading / unloading position, the rotational force of the upper roller shaft 131 is not transmitted to the upper roller 130 due to the action of the one-way clutch 132. Film is not conveyed. In this case, a slip phenomenon occurs between the film and the upper roller 130.

The lower roller 140 rotates together with the upper roller 130 when the upper roller 130 rotates, and serves to transport the film. As described above, the tray 120 is involved in the conveyance of the film while rubbing with the upper roller 130 only when the tray 120 is drawn from the food container loading / unloading position to the film sealing operation position.

The lifting lowering sealing / cutting unit 160 may move upward and downward at a film sealing operation position to serve to cut unnecessary portions while heat-sealing the film on top of the food container 115.

The elevating sealing / cutting unit 160 is connected to the heat fusion plate 161 to heat seal the film on the top of the food container 115, the heat fusion plate 161 and the film to the food container 115 A cutting blade 162 for cutting into the upper shape of the, and the elevating module 163 is connected to the heat fusion plate 161 to drive the elevating plate 161 up and down.

The heat fusion plate 161 serves to heat-bond the upper portion of the food container 115 while melting the film by the heat of the heater. The heat fusion plate 161 has a shape similar to that of the upper area of the food container 115.

The cutting blade 162 cuts the film into the upper shape of the food container 115. Since the upper shape of the food container 115 in the present embodiment is a rectangular shape, the cutting blade 162 is a rectangular shape to cut the film into the upper shape of the food container 115.

The elevating module 163 includes a motor 163a, a cam 163c connected to the motor shaft 163b of the motor 163a, an upper portion of the cam 163c, and a lower portion of the thermal fusion plate 161. And a lifting member 163d connected thereto.

Thus, when the motor 163a is operated and the motor shaft 163b is rotated, the lifting member 163d may move up and down as the cam 163c is operated while being eccentric at the shaft center of the motor shaft 163b.

Hereinafter, the operation of the food container packaging apparatus of the present embodiment will be described.

First, when the operation switch (not shown) is pressed, the tray 120 is drawn out to the food container loading / unloading position inside the apparatus main body 110.

When the food container is seated and loaded on the tray 120 drawn out to the food container loading / unloading position, and the operation switch is pressed again, the tray 120 together with the food container is introduced into the film sealing operation position in the apparatus main body 110. .

At this time, as described above, the rack gear 125 is coupled to the upper rear side of the tray 120, and the rack gear 125 is connected to the upper roller shaft 131 of the upper roller 130. As the 120 is drawn into or taken out of the film sealing operation position or the food container loading / unloading position, the rack gear 125 is also drawn in or taken out together, and at the same time, the upper roller shaft 131 of the upper roller 130 is also interlocked. Is rotated.

Since the one-way clutch 132 is provided between the upper roller shaft 131 and the upper roller 130, the rotational force of the upper roller shaft 131 is the upper roller 130 only when the tray 120 is drawn into the film sealing operation position. The film is transferred to the film sealing operation position by the friction force of the upper roller 130 and the lower roller 140.

However, when the tray 120 is withdrawn to the food container loading / unloading position, the film is conveyed because the rotational force of the upper roller shaft 131 is not transmitted to the upper roller 130 due to the action of the one-way clutch 132. It doesn't work. In this case, a slip phenomenon occurs between the film and the upper roller 130.

As a result, when the tray 120 is withdrawn to the food container loading / unloading position, the film is slipped without being transported, and the upper roller 130 and the lower roller 140 only when the tray 120 is drawn into the film sealing operation position. By the frictional force of the film can be transferred to the film sealing operation position.

As such a structure is applied, a structure in which the film is not stretched as in the past can be realized, and thus a problem in which the film is unnecessarily rolled up can be solved.

On the other hand, when the film is disposed on the upper portion of the food container by the above action, the heat-sealing plate 161 and the cutting blade 162 attached to the lowering operation by the cam is lowered to the film disposed on the upper portion of the food container After pressing the film to the food container side, it is raised back to its original position.

When the heat-sealing plate 161 and the cutting blade 162 attached thereto presses the film toward the food container side, the food container descends by the compression position of the spring 171 as the spring 171 of the spring plunger 170 is compressed. At this time, the heat-sealed plate 161 is sealed by heat-sealing the film and the food container, the cutting blade 162 cuts the film into the upper shape of the food container.

As such, the film is cut by the cutting blade 162, only the upper shape of the food container, that is, the rectangular shape is perforated in the film and thermally fused to the upper surface of the food container, and the remaining films are continuously discharged, as before, the upper part of the food container 115. There is no film on the left, thus can effectively solve the uncomfortable problem of removing the remaining left on the top of the food container 115 as before.

When the heat fusion is completed, the heat fusion plate 161 and the cutting blade 162 attached thereto are raised and returned to their original positions, and at the same time, the spring 171 is expanded to the original state so that the spring plunger 170 is also placed in the original position. The food container 115 may be raised to a position that is easy to take out of the tray 120.

According to the present embodiment having such a structure and operation, as well as the problem of poor operation due to the film is curled up as in the conventional, and the inconvenience of removing the remaining scrap on the top of the food container, and lift type food container lifting structure It is possible to efficiently solve problems such as malfunction caused by the operation.

As described above, the present invention is not limited to the described embodiments, and various modifications and changes can be made without departing from the spirit and scope of the present invention, which will be apparent to those skilled in the art. Therefore, such modifications or variations will have to be belong to the claims of the present invention.
