Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention mainly relates to a container body, which is molded in a shape in which a peripheral wall is hung from a peripheral end of a top wall and is sterilized, in a container body in a sterile atmosphere. The present invention relates to a lid supply device for supplying.

[Conventional technology]

As a conventional means for supplying the sterilized lid to the container body, there is, for example, one disclosed in Japanese Patent Laid-Open No. 59-115221. This is because the lower surface of the plate-shaped lid is sucked by the vacuum head and then rotated 180 degrees, the suction is stopped immediately above the container body, the lid is opened, and the means for supplying it to the mouth of the container body is is there.

[Problems to be Solved by the Invention]

There are some problems in such a conventional technique. One of them is a large opening between the room for sterilizing the lid and the room for supplying the lid because of the structure in which the lid is sucked to rotate 180 degrees as seen in FIG. 1 of the prior art. It is necessary to have a department. Therefore, in this conventional technique,
It is assumed that the lid sterilization, lid drying, and lid supply are performed in one room. The fact that the rooms where the different processes are performed are the same means that, for example, atomized hydrogen peroxide for lid sterilization leaks out and waste occurs, or it enters the container filled with the contents. It is not preferable to do so.

Further, in the above-mentioned conventional technique, since the flat plate-shaped lid is intended, it is possible to convey the lid directly above the container body by rotating the vacuum head by 180 degrees, but from the peripheral edge of the top plate to the peripheral wall. In the case of a lid with a hanging shape, it is necessary that the peripheral wall of the lid does not hit the container body when the vacuum head is rotated, and therefore the distance between the top wall of the lid and the container body is that much. If the lid is opened and dropped from there, there is a risk that the lid will not be properly supplied to the container body. Therefore, there remains a problem that the conventional device for supplying a flat plate-like lid cannot be used as it is for a lid having a peripheral wall.

The present invention has been devised in view of these problems, and enables the lid sterilization chamber, the lid supply chamber, etc. to be isolated, and the lid having a peripheral wall can be easily and reliably supplied to the container body. It is a technical problem to provide a lid supply device.

[Means for solving the problem]

As a means therefor, the present invention comprises a cam body 2, a rotating body 3, a receiving body 4, and a chuck body 5.

The cam body 2 has a first cam surface 6 and a second cam surface 7, which draw different cam curves in the vertical direction, arranged in parallel and fixed.

The rotating body 3 is rotatably assembled to an ascending / descending lift body 8 and moves up and down together with the ascending / descending body 8 to come into contact with the first cam surface 6 and the second cam surface 7 to have a posture of 90 degrees. It is rotationally displaced.

The receiving body 4 is fixedly assembled to the rotating body 3, and maintains a vertical posture with respect to the ascending / descending direction at the ascending limit position and maintains a posture in the ascending / descending direction at the descending limit position.
Further, in the ascending limit, the structure is such that the top surface b and the lower portion of the peripheral wall c of the lid a conveyed in a rollover posture are held.

The chuck body 5 is attached to the receiving body 4 so as to be openable and closable, holds at least the bottom surface of the lid a inside the receiving body 4 in the ascending limit, and holds the erect posture lid a in the descending limit. To open at least one pair.

[Action]

The operation of the present invention will be described with reference to FIGS. 1 and 2.

First, the rotating body 3, the receiving body 4, and the chuck body 5 that are integrally assembled to the lifting body 8 are in the upper limit, and therefore the receiving body 4 maintains its posture in the direction perpendicular to the vertical movement direction. In the state in which the lid 4 a is being conveyed, the lid a conveyed from above enters the receiving body 4. The lid a is
The top surface b and the lower peripheral surface are held by the receiving body 4. After the entry position of the lid a is completed, the chuck body 5 which has been open until then is closed to hold at least the lower surface of the lid a.

Next, the lifting / lowering body 8 is displaced downward. At this time, the rotating body 3 comes into contact with the first cam surface 6 and the second cam surface 7 of the cam body 2 to rotate its posture by 90 degrees downward from the previous vertical direction, and is further displaced downward to descend. Reach the limit position.
In this state, the lid a in the receiving body 4 is in an upright posture, and the downward dropping is prevented by the chuck body 5 holding the lower surface thereof in contact therewith.

After reaching the lower limit, the chuck body 5 forms an open state to open the lid body a and drop the lid body a onto the mouth portion of the container body d to complete the supply of the lid body a. .

Then, it is displaced upward to supply the next lid a, the rotating body 3 comes into contact with the first cam surface 6 and the second cam surface 7 in the middle of the displacement, and 90 degrees in the direction opposite to the downward displacement. The rotation causes the receiving body 4 to return to the vertical posture with respect to the vertical movement direction.

〔Example〕

 1 and 2 show an embodiment of the present invention.

The cam body 2 is hung from a partition wall 18 which separates the lid sterilization chamber and the chamber for supplying the lid a. In this cam body 2, a first cam surface 6 having a concave surface 13 and a second cam surface 7 having a convex surface 14 are formed with an intermediate groove 20 interposed therebetween.

The rotating body 3 is axially supported laterally with respect to the elevating body 8 and has a first cam follower 10 for sliding the first cam surface 6 at the end of a rotary shaft 15 thereof and sliding on the second cam surface 7. It has a second cam follower and a second cam follower 11.

As shown in FIGS. 3 and 4, the receiving body 4 is supplied from the lid sterilizing device (in this case, falling supply) from the continuous plate 23 fixedly assembled to the rotary shaft 15 of the rotating body 3. A flat plate-shaped contact plate 21 with which the top surface b of the lid a comes in contact is provided, and from this contact plate 21 to the lower part of the peripheral wall c of the cover a (in this case, the intermediate part of the peripheral wall c and slightly below it). A wall plate 22 that abuts is erected.

A pair of chuck bodies 5 are provided, and an upper portion thereof is rotatably supported by two shaft pieces 19 fixedly assembled to the rotary body rotating shaft 15 at a right angle. The cylinder 32 provided between the chuck bodies 5 swings the upper end portion to achieve the opening and closing. As shown in FIGS. 5 and 6, the tip of the chuck body 5 is formed with a hook piece 24 that abuts the lower surface of the lid body a, and
From 24, a holding piece 9 is provided so as to come into contact with the upper portion of the peripheral wall c of the lid a when the lid a is in the overturned state. By forming the holding piece 9, it is possible to hold the lid a in the up-down, front-rear, left-right directions. Therefore, when the lid a is rotated from the overturned posture to the upright posture, the lid a falls off from the receiving body 4. Never. In order to hold the lid a by the holding piece 9, the wall plate 22 of the receiving body 4 is formed with a recessed groove 31 having a width such that the holding piece 9 can enter the position.

FIG. 7 and FIG. 8 explain the 90 degree rotation of the rotating body 3 by showing the loci (cam diagram) of the cam body 2 and the cam follower. All three cam followers are equidistant from the center of the rotary shaft 15. A concave surface 13 is formed on the first cam surface 6 on which the first cam follower 10 slides, and a convex surface 14 is formed adjacent to the concave surface 13 on the second cam surface 7 on which the second and third cam followers 12 slide. Has been done.

When the rotating body 3 is in the upper limit, the first cam follower 10 contacts the upper vertical surface 16 of the first cam surface 6, and the second cam follower 11 contacts the upper end vertical surface 16 of the second cam surface 7. By these actions, the rotating body 3 maintains the vertical posture with respect to the vertical movement direction. At this time, the third cam follower 12 is idle.

When the rotating body 3 is displaced slightly downward from this state, the first cam follower 10 slides on the concave surface 13 of the first cam surface 6, and the second cam follower 11 starts sliding on the convex surface 14 of the second cam surface 7. When the first cam follower 10 is in contact with the deepest part of the concave surface 13, the first cam follower 10
The center of the rotary shaft 15 is located on the same horizontal line, and both the second cam follower 11 and the third cam follower 12 are in contact with the inclined surface 17 forming the convex surface 14 of the second cam surface 7.

When the downward displacement of the rotating body 3 progresses further from this state, the position of the first cam follower 10 which was lower than the rotary shaft 15 up to that point reverses at the deepest part of the concave surface 13 and is positioned higher than the rotary shaft 15. Will be done. And the first cam follower
When 10 is in contact with the vertical portion below the concave surface 13, the third cam follower 12 is in contact with the vertical surface 16 of the second cam surface 7, and the attitude of the rotating body 3 is the same as the vertical movement direction. It is maintained in the direction. At this time, the second cam follower 11 is idle.

The vertical surface 16 below the concave surface 13 or the convex surface 14 is set to a length such that the rotating body 3 or the like, which has completed 90-degree rotation, can be slightly displaced downward in the completed posture. By doing so, even if the lid a has a large height of the peripheral wall c, it can be lowered until the lower surface of the top wall thereof comes very close to the upper end surface of the mouth portion of the container body d. The supply of a can be achieved.

FIG. 9 shows a usage example of the device of the present invention. This is an aseptic filling machine, and a sterilizing agent fixing unit 25 for adhering hydrogen peroxide to the container body d, a hot air sterilizing unit 26 for supplying hot air to the container body d for sterilization, and a lid for sterilizing the lid a It has a sterilization unit 28, a filling nozzle 27, etc., and is composed of an aseptic filling unit 29, etc., for filling contents and fitting the lid a. The lid supply device 1, which is the device of the present invention, is located below the lid sterilization unit 28 and supplies the lid a falling from the lid sterilization unit 28 to the container body d. The lid a supplied on the container body d is heated and pressure-bonded by the sealing device 30 in the next step, and is brought into close contact with the opening of the container body d.

〔The invention's effect〕

As described above, according to the present invention, since the lid body received in a rollover posture is received and lowered while rotating 90 degrees and is supplied to the container body, it is provided between the lid body sterilization chamber and the lid body supply device 1. Needs only to form a narrow opening for the lid to pass through, so that each room can be made independent and waste of atomized hydrogen peroxide and adhesion to the contents can be reliably prevented. You can

In addition, since the lid is supplied to the container body only by the conventional rotating operation, the rotation is moved up and down, so that the lid having the peripheral wall can be accurately supplied. Be effective.
