[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for sealing an egg container made of a synthetic resin sheet in which a body portion and a lid portion each having a concave portion for accommodating eggs are integrally connected via a bendable connecting edge portion. Regarding

[0002]

2. Description of the Related Art As shown in the perspective view of FIG. 4, a conventional egg container 10 comprises a body portion 1, a lid portion 2 and a hinge portion 3 for flexibly connecting these two portions 1, 2. The synthetic resin sheet is vacuum-molded or blow-molded to be integrally molded, and the body part 1 and the lid part 2 have partition walls.
It is provided with a concave portion 12 for accommodating a plurality of chicken eggs partitioned by 11 and a peripheral edge portion 5.

Therefore, as a device for sealing the sealing portion formed on the peripheral edge portion 5 so that it can be easily and safely opened, the peripheral edge portion 5 of the egg container is sealed with an adhesive tape, and the sealed adhesive tape Leave part of it protruding from the end,
There is known a device in which the protruding adhesive tape is pinched with a fingertip and pulled laterally so that the adhesive tape can be peeled off from the peripheral edge portion 5 and easily opened.

A conventional egg container sealing device is a plan view of FIG.
As shown in (a) and side view (b), while putting an egg in the body part 1 of the egg container 10 and pressing the lid part 2, a conveyor 20 on which the egg container 10 is placed and conveyed, and a side of this conveyor 20. A roller 21 with a flange and a roller 22 having a V-shaped groove for guiding the adhesive tapes 19 arranged along one side to the peripheral portion 5 of the egg container 10 and a row of these rollers 21, 22 are arranged next to each other. A pair of press rollers 23 for pressing the adhesive tape 19 folded in two from above and below the peripheral edge portion 5 of the egg container 10,
A cutter 24 for cutting the adhesive tape 19 and a guide roller 16 for supplying the adhesive tape 19 from the reel 18 to a roller 22 having a V-shaped groove through a roller 21 with a flange and a center line of the adhesive tape 19. And a roller 17 with a ridge for making a fold line 15 from the adhesive surface side.

Further, an upper guide plate 25 for pressing the lid portion 2 of the egg container 10 to be conveyed is provided above the conveyor 20, and the egg is provided on the opposite side of the conveyor 20 facing the row of rollers 22 and 23. A side guide plate 26 is provided for pushing the hinge portion 3 of the container 10 with a spring or the like. These two guide plates 2
While keeping the peripheral portion 5 of the egg container 10 containing the eggs closed by 5, 26, the peripheral portion 5 is fitted into the V-shaped groove of the roller 22 as shown in the sectional view of FIG.

Next, the operation of the conventional sealing device having the above structure will be described. First, pull out the adhesive tape 19 from the reel 18, fold the adhesive tape 19 by hand on the peripheral portion 5 of the first egg container 10 in which the egg is put and the body part 1 and the lid part 2 are closed. Paste and place on conveyor 20, conveyor 20, upper guide plate 25, side guide plate 26, roller
Insert in the space surrounded by rows 22 and 23 (see Fig. 2).

At this time, the adhesive tape 19 continues up to the reel 18. Next, put eggs in the body part 1 and the lid part 2
While holding down, place the second egg container 10 on the conveyor 20, operate the conveyor 20 and each roller 21, 22, 23,
The first and second egg containers 10 are conveyed by a length t longer than the length of the egg container 10. During transportation, the peripheral edge portion 5 of the first egg container 10 is sandwiched between the press roller pair 23 and passes, so that the adhesive tape 19 is adhered to the overlapped peripheral edge portion 5. When the conveyance is completed, the cutter 24 descends and cuts the adhesive tape 19. At the time of this cutting, the adhesive tape 19 is cut so that the end portion thereof protrudes from the egg container 10 by a length t.

In succession to the first egg container 10, the second egg container 10 is conveyed at an interval of t. During this transportation, the lid portion 2 of the second egg container 10 is pressed by the upper guide plate 25, and the adhesive tape 19 is attached to the peripheral edge portion 5. The adhesive tape 19 is V-shaped. It is bent by the roller 22 having the groove and is on standby by sandwiching the peripheral edge portion 5.

Similarly, when the third egg container 10 is placed on the conveyor 20, the second egg container 10 is sealed and carried out.

In the egg container 10 sealed in this way, the adhesive tape 19 protrudes from the peripheral edge portion 5 by the length t. Therefore, by grasping the protruding adhesive tape 19 and pulling it in the lateral direction, The adhesive tape 19 can be peeled off and easily opened.

[0011]

In such a conventional apparatus, before feeding the adhesive tape 19 to the roller 22 having the V-shaped groove, the adhesive tape 19 is attached to the center line of the adhesive tape 19 from the adhesive surface side. Since the roller 17 with ridges is used to make the fold line 15, there is a problem that the adhesive surface adheres to the roller 17 with ridges and the adhesive tape 19 is entangled.

Therefore, the egg container sealing device of the present invention is
The present invention was devised in order to solve the problems of such a conventional device.

[0013]

The egg container sealing device of the present invention comprises a hinged egg container 10 having a body portion 1, a lid portion 2 and a hinge portion 3 connecting these two portions flexibly. A device for sealing the peripheral portion 5 of the body portion 1 and the lid portion 2 facing the portion 3 with an adhesive tape 19, which is provided on a side of the conveyor 20 for conveying an egg container 10 containing eggs. Ridge on the entry side of the adhesive tape that has a ridgeline
A jig 30 for making a crease on an adhesive tape, which is composed of a groove 31 on the exit side having a valley line which intersects with the ridge line and the ridge line 30.
A roller 22 having a V-shaped groove for pressing the adhesive tape 19 having a crease on the peripheral edge portion 5 of the egg container 10 which is overlapped with the adhesive tape 19 while bending it in the longitudinal direction thereof;
A press roller pair 23, which is provided on the side of the adhesive tape 19 and presses the bent adhesive tape 19 against the overlapped peripheral edge portion 5 for adhesion, and a cutter 24 for cutting the adhered adhesive tape 19. There is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Similar to the conventional egg container sealing device shown in FIG. 1, a sealing device of the present invention comprises a conveyor 20 on which an egg container 10 is placed and conveyed, a roller 22 having a V-shaped groove, and A press roller pair 23 for pressing the adhesive tape 19 arranged following the roller 22 and folded in two from above and below the peripheral edge portion 5 of the egg container 10, and a cutter for cutting the adhesive tape 19.
24 and.

In the sealing device of the present invention, the jig 30 shown in FIG. 3 is provided at the position of the guide roller 16 between the reel 18 of the adhesive tape and the roller 22 having the V-shaped groove. The guide roller 16 and the flanged roller 21 are omitted.

The jig 30 shown in FIG. 3 is used as a means for making a crease at the center line of the adhesive tape 19 when the adhesive tape 19 is supplied from the reel 18 to the roller 22 having a V-shaped groove. It is a thing.

The jig 30 has an adhesive tape 19 having a ridge.
And a groove 32 having a valley line continuing from the ridge line.
The ridge 31 is formed on the entrance side of the adhesive tape 19, the groove 32 is formed on the exit side of the adhesive tape 19, and the ridge line and the valley line intersect.

When the back surface of the adhesive tape 19 (the surface on which the adhesive is not applied) is passed along this jig 30, the adhesive tape 19 is made into a V-shaped crease without touching the adhesive surface. be able to.
