Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for closing a lid of a hermetically sealed container, and more particularly, to a device for fitting a lid of the hermetically sealed container whose interior is closed by closing the lid to a container body.

[0002]

2. Description of the Related Art An apparatus a as shown in FIG. 8 is used to close a lid of a widely used polyethylene food storage container before shipping before shipment, and the container is manually operated. The device a is formed by a table b and a plate d attached to the table b by a hinge c and rotatable up and down. The plate d is provided with a protrusion e in the center of the lower surface. FIG. 8 is provided for the purpose of explaining the operation of the tool a, and details of the tool a are simplified or omitted.

[0003] The method of using the device a will be described. First, as shown in FIG.
Place the container body t. Then, the lid f is placed on the container body t. From above, the device a
Is pressed down. Depressing the plate d is manually performed by a person.

On the other hand, when the relationship between the lid f and the container body t is viewed along the above-mentioned operation steps, first, as shown in FIG. On the other hand, the lid f is placed so as to cover the opening above it. A fitting groove m is formed in the peripheral portion of the lid f, and the fitting groove m faces the peripheral portion s of the container body t located below.

[0005] Next, as shown in FIG. 9 (B), with the above-mentioned plate d which is manually pushed down, the lid f is attached to the container body t.
Pressed against. At this time, the protrusion e at the center of the lower surface of the plate d presses the center of the lid f. By such a pressing method, the lid f is bent downward at the center portion, and the container body t
The air k inside is expelled to the outside.

As a result, the lid f inserts the peripheral portion s of the container body t into the fitting groove m without being pushed back by the air inside the container body t as shown in FIG. 9C. In this manner, the lid f smoothly fits into the container body t, and the lid closing of the container is completed.

As described above, the center of the lid f is pressed by the protruding portion e at the center of the lower surface of the plate d, and the air inside the container body t is evacuated from between the peripheral edge of the lid f and the container body t. And the container main body t, the positioning must be performed accurately so that the center of the lid b abuts on the protruding portion e.

In order to carry out the work efficiently, it is assumed that a container is automatically sent to the lower side of the plate d using a conveyor instead of the table b, and the above-mentioned pressing operation is also automatically performed on the plate d using an actuator. Even if it is to be performed, as described above, it is necessary to accurately position the protruding portion e at the position where the plate d performs the pressing so that the protruding portion e contacts the center of the lid b.

For this reason, even if the work is lined as described above, the conveyor is temporarily stopped when the container body t whose lid is closed reaches the pressing position of the plate d, and the operation of the plate d is started. Must be performed, and during this operation the entire line will stop. Even if the pressing operation is completed and the line is restarted, the conveyor will be stopped again when the container body t to be closed next arrives. Therefore, the apparatus repeats such stopping and restarting of the line.

However, operating the line intermittently in this way is inefficient, and a method of sequentially performing operations without stopping the line has been required. However, the device having the above-described structure requires precision in positioning the lid of the container to be pressed, and therefore, the above-described intermittent operation process is inevitable.

[0011]

SUMMARY OF THE INVENTION In view of the above background, the present invention makes it possible to reliably perform air bleeding while eliminating the need for precise positioning required for air bleeding. It is an object of the present invention to solve the above problem by efficiently closing the lid of the sealed container without stopping the flow even when the line is formed.

In accordance with the movement of the container, the moving means 1 and the contact portion 2 sandwich the container, and fit the lid to the container body sequentially from the front side to the rear side in the moving direction.

By adopting the above configuration, if the container is going to pass under the contact portion 2, each part of the lid is necessarily pressed down from the end (front side in the traveling direction) to the contact portion 2. As a result, the container is hermetically sealed while air is evacuated sequentially from the front to the rear of the container. Therefore, unlike the conventional case where the entire lid is fitted to the container body at one time, there is no need to perform accurate pressing alignment in consideration of air release. Therefore, it is possible to continuously perform the closing operation of the lid in accordance with the flow of the container carried to the moving means 1 without stopping the moving means 1 for each positioning for such pressing.

According to a second aspect of the present invention, there is provided an apparatus for closing a lid of a hermetic container according to the first aspect of the present invention, wherein the abutment portion 2 is provided rotatably. The roller is characterized in that

By adopting the above configuration, the contact portion 2
However, the device does not cause a great resistance to the movement of the container underneath, and the device can smoothly fit the lid and feed the container in the moving direction.

The two side plates 30a, 30a have through holes 30d, 30d penetrating from the upper part to the lower part at the front part and the rear part, respectively.
Is provided. The guide column 31 is loosely fitted in the through hole 30d. The height of the contact portion 2 connected to the plate-like body 36 can be adjusted by operating the handle 35 to move the hanging bar 34 up and down. At this time, the contact part 2
The left and right side plates 30a, 30a holding the guide are guided by guide posts 31.

The contact portion 2 comprises a plurality of rollers 20 as shown in FIG. Each roller 20 ... 20
Is passed between the side plates 30a, 30a of the holding member 30, and is fixed to the side plates 30a, 30a. 21 ... 2
Reference numeral 1 denotes the axis of the rollers 20.

As shown in FIG. 4 (A), the rollers 20... 20 constituting the contact portion 2 are, in detail, a plurality of introduction rollers 20a. 20b, which are two kinds of roller groups (introduction roller group P and horizontal roller group Q) of a plurality of main rollers 20b... 20b which are arranged at the lowest position after passing through 20a (introduction roller 20a). 20a are referred to as shafts 21a... 21a, and the shafts 20 of the main rollers 20b.
Are hereinafter referred to as shafts 21b... 21b).

First, each of the introduction rollers 20a... 20a constituting the introduction roller group P is arranged at a gradually lower position as it advances in the direction in which the container is conveyed, and the lower surface (of the moving means 1) of the belt 11 is moved. 11a gradually narrows.
Looking at the individual introduction rollers 20a... 20a, this indicates that the introduction roller 20a on the left side is closer to the introduction roller 20a located on the right side as shown in FIG.
This means that it is disposed at a lower position, and when viewed as a whole as the introduction roller group P, this introduction roller group P
Is inclined so as to become lower toward the direction X of movement.

Each of the main rollers 20b... 20b constituting the horizontal roller group Q is disposed at a lower position than the introduction roller group P. The main rollers 20b... 20b constituting the horizontal roller group Q are located at the same height. As shown in FIG. 4B, an interval H between the main roller 20b and the surface 11a of the belt 11 (of the moving means 1) is set to be substantially the same as the upper and lower thicknesses of the sealed container.
Each of the introduction rollers 20a... 20a of the introduction roller group P has substantially the same outer diameter. Each of the main rollers 20b... 20b of the horizontal roller group Q has substantially the same outer diameter. The introduction rollers 20a... 20a and the main roller 20b
... 20b have substantially the same outer diameter.

By setting the above-mentioned interval H to the above-mentioned width, as shown in FIG. 5 (A), each part of the lid f of the container going to pass this interval H From the end (front side), it is sequentially pressed by the contact portion 2, whereby the container is hermetically sealed while air is evacuated sequentially from front to back.

More specifically, the container body t which moves from the right hand to the left hand in FIG. As described above, the introduction rollers 20a... 20a constituting the introduction roller group P gradually narrow the interval with the surface 11a of the belt 11 as the container advances. The lid f is gradually pressed down on the container body t with the movement. When the container reaches below the horizontal roller group Q, the container is sandwiched between the main rollers 20b... Then, the lid f is completely fitted to the container body t. As described above, by closing the lid f in order, the air in the container is sequentially extracted from the front side to the rear side. Therefore, by closing the lid in this order from the end (front side), even if the direction of the container is shifted with respect to the movement direction X, the above-described container can be degassed without any problem. Therefore, unlike the conventional case where the entire lid is fitted to the container body at one time, it is not necessary to perform accurate pressing alignment in consideration of air release.

As described above, the contact portion 2 and the pressing means 4
Since the holding member 30 is axially fixed to the side plates 30a, 30a, the holding member 30 can be moved up and down to some extent by the projections 30c... 30c interposed between the upper plate 30b and the plate-like body 36. However, the above-mentioned distance H with respect to the surface 11a of the belt 11 is not necessarily unchanged at all. In particular, if the container is set so as to be biased by the springs 30c... 30c while passing through the contact portion 2, the container can be more securely and smoothly closed. However, even when the distance H between the main roller 20b and the belt surface 11a is set to be smaller than the thickness of the sealed container in a state where there is no container therebetween, at least when the container passes through, the protrusions 30c ... 3
The main roller 20b (holding member 30) is adjusted so as to be able to retreat upward until it has the same width as the thickness of the container (after sealing) against the bias of 0c.
This is because it is necessary to pass the container.

If the abutting portion 2 can move up and down slightly by providing the above-mentioned other splicing strips 30c... 30c, even if the container moves up and down a little while moving due to the waving of the belt of the belt conveyor, etc. The container can be smoothly moved in response to such unexpected movement.

After the lid is closed, when the container tries to escape from the main rollers 20b.
Since the front of the container is opened while being held down, the front of the container tends to float upward. In order to prevent such lifting, FIG.
As shown in (A), a separate pressing means 4 is provided at a point where the roller has passed through a group of rollers constituting the contact portion 2.

The holding means 4 is a roller. The rollers serving as the pressing means 4 also have the side plates 30a, 30a of the holding member 30 similarly to the above-described rollers constituting the contact portion 2.
It is passed between and is fixed to both side plates 30a, 30a.
Numeral 40 indicates the axis. The roller of the pressing means 4 is also
It has substantially the same outer diameter as the individual rollers constituting the contact portion 2.

The pressing means 4 is, as shown in FIG. 4A, a main roller located at the earliest position in the moving direction X of the horizontal roller group Q (located at the leftmost position in FIG. 4A). 20
4B is located further in the direction of movement X than b. (It is located on the left hand side of FIG. 4A with respect to the main roller 20b.) As shown, the roller of the holding means 4 is located ahead of the main roller 20b in the direction of movement X within a range not exceeding the front and rear length of the container from the foremost main roller 20b. The roller of the holding means 4 is a belt 11
It is located above the belt 11 with an interval larger than the above-mentioned interval H with respect to the front surface 11a. If the distance is the same as the distance H, there is a fear that the front of the container may be lifted even after passing through the pressing means 4. However, for the purpose of suppressing the rising in front of the container passing through the contact portion 2,
It is provided at a position corresponding to the upper side of the floating container.

The above pressing means 4 presses the upper part of the container passing through the abutting portion 2 to prevent the container from being lifted up, thereby enabling the container to move smoothly.

If the size of the container for closing the lid changes,
By operating the handle 35 described above, the height of the contact portion 2 and the pressing means 4 can be adjusted to cope with the problem.

In the above embodiment, when the container has not passed, the main roller 20b and the belt 11 surface 11
The distance H with respect to a is smaller than the upper and lower thicknesses of the sealed container, and is set to be substantially the same width as the upper and lower thicknesses of the sealed container when passing through the container to resist the urging of the spring. However, the present invention is not limited to such a setting. For example, when the container is not passing, the main roller 2
The distance H between the belt 0b and the surface 11a of the belt 11 is set to be approximately the same as the upper and lower thicknesses of the sealed container. It is also possible to set and implement such that the bias is applied.

Further, the contact portion 2 is shown as being constituted by a plurality of rollers, but the contact portion 2 may be formed by a single roller. . In this case, the pressing means 4 is not limited to the one provided at a position higher than the contact part 2 as in the above-described embodiment, but is the same height as the contact part 2 (the surface 11a of the belt 11). (A height from above). Further, when the contact portion 2 is formed by a plurality of rollers, it is also possible to form an annular belt over the entire roller that constitutes the contact portion 2 so that the rollers work together. is there.

Further, the holding means 4 may be constituted by something other than a roller. For example, the present invention can be implemented even if a horizontal bar formed of a material having low surface resistance is fixed so as not to rotate. Further, the holding means 4 can be embodied as being supported by a part other than the holding member 30 of the contact part 3.

In the embodiment shown in FIGS. 1 to 5,
Introducing rollers 20a ... 20a and main rollers 20b ... 20b
Are arranged on the side plates 30a, 30a.
Although it is determined by the positions of the holes for receiving the shafts 21a... 21a, 21b... 21b of each roller, the inclination angle of the introduction roller group P can be adjusted by making the positions of the holes variable. is there.
