Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an arrangement conversion/orientation device for bottles, boxes, etc.

In general, for example, in automatic machines that attach labels to bottles or print on parts of boxes, if the cross section of the bottle or box is circular, it can be attached to any outer circumferential position regardless of the orientation of the bottle or box. Labels can be pasted and printed, but bottles and
If the cross-section of the box is circular or square, and the outer circumference position for label attachment or printing is determined due to a pattern, etc., the bottle/box should be inspected before being transported to the automatic machine mentioned above. It is necessary to align the directions.

By the way, as shown in FIG. 1, a bottle 1 with a circular cross section,
......1 is lapel attachment position 2,...
....2, the chucking mechanism 4 grabs the bottles 1,...1 from the 1 dozen cases 3 stored in 3rd row and 4th row, and 1,...
1 is moved onto belt conveyors 6, 6 via a mechanism 5 for arranging them in 2 columns and 6 rows, and transported to an automatic label pasting machine 7 by the belt conveyors 6, 6, Due to the installation and performance issues of the automatic label pasting machine 7,
For example, in the figure, the bottle 1 on the upper belt conveyor 6,
......1 label pasting position 2,...
...It is necessary to change the direction of the conveyor belt 2 by 180 degrees, and for this purpose, conventionally, a direction change device 8 has been installed separately in the middle of the belt conveyor 6, making the configuration and control for the direction change complicated. However, there was a problem that the equipment cost was high.

Furthermore, in U.S. Pat. No. 3,220,566, a device is proposed in which all the container holders are supported by a rotation mechanism and rotated concentrically in the same direction at a certain angle when changing the arrangement by a drive mechanism. It is necessary to rotate the container holders, which complicates the rotation mechanism, and in the case of deformed bottles, etc., they bump into each other, so it is necessary to widen the mounting interval of the container holders.

By the way, in Japanese Patent Application No. 51-137912 (title of the invention "Container Conveying Device"), the present applicant disclosed that in a conventional container conveying device, the center line of the container arrangement fluctuates before and after changing the container arrangement. In order to solve the problem that it was not only inconvenient when transferring it on a conveyor, etc., but also caused the container to fall over, or was a hindrance to various equipment in subsequent processes.
In order to provide a container conveying device in which the center line of the containers does not change even if the arrangement of the containers is changed, all the chucks in multiple rows are divided into two symmetrical blocks in the rows, each with a separate block. A pair of first links and a pair of second links that are attached to a first moving board and a second moving board and protrude in opposite directions from the first and second rotating shafts, which are vertically provided from the container body, are each integrated. The first movable board and the second movable board are rotatably attached to the tips of the pair of first and second links, and a drive gear is attached to a drive shaft that rotates by rotational force. The driving gear is connected to a first rotating shaft provided on the first rotating shaft and a second rotating shaft, respectively, which are vertically provided from the vessel body via a rotational force transmission mechanism.
meshing with the link gear and the second link gear, respectively;
The movable substrate and the second movable substrate are each moved in opposite directions by approximately 18 mm.
We proposed an arrangement conversion device for bottles, boxes, etc. that has an arrangement conversion configuration that rotates 0 degrees.

The present invention relates to the improvement of the apparatus for changing the arrangement of bottles, boxes, etc., and focuses on the fact that the chuck grasps and holds the bottles, boxes, etc. individually, and eccentrically rotationally supports only the specific chuck whose direction should be changed after the arrangement is changed. The specific chuck can be eccentrically rotated in any direction by being supported by a shaft, and the rotation structure is simple.
This design is designed to prevent deformed bottles from hitting each other without increasing the distance between the chucks.

Therefore, in the arrangement conversion device for bottles, boxes, etc., the present invention provides two chucks of the first and second movable substrates after the first and second movable substrates are rotated approximately 180 degrees. The chucks in one of the chuck rows are
The movable base plate and the second movable base plate are supported and attached to the eccentric rotation support shaft, and a pinion is fixed to the eccentric rotation support shaft, and the pinion meshes with the rack of each cylinder of the first movable base plate and the second movable base plate. The present invention is characterized by having a direction changing configuration for rotating the specific chuck in the same direction and at the same angle.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The container body 16 of the chucking mechanism A has first and second rotating shafts 1.
7a and 17b are rotatably mounted, and the shaft portion 19 at the tip of the first and second links 18a and 18b, which are integrally provided at the lower ends of the first and second rotation shafts 17a and 17b, is connected to the first

As shown in the figure, an expansion/contraction part 26 that expands and contracts with air pressure is provided in the cylinder 25, and the mouth of the bottle 1 can be attached and detached by pressurizing air into or removing it from the mounting board 12.

In this chucking mechanism A, for example, when taking out bottles 1, 1, 1 from case 3 in which bottles 1, 1, 1 are arranged in 3 columns and 4 rows, When the chucking mechanism A is moved above the case 3 along a guide rail (not shown), the chucking mechanism A is lowered and the chuck 10 grips the bottles 1, . . . 1.

Next, when the chucking mechanism A moves in the direction of the belt conveyor 6, the chucking mechanism A rises, and the bottles 1,...

As is clear from the above description, in the present invention, all of the chucks are divided into two symmetrical blocks in a matrix, and each block is attached to the first and second moving substrates, respectively. Since it has an arrangement conversion configuration in which the first and second movable substrates are rotated approximately 180 degrees in opposite directions, it is possible to change the number of rows and columns in the arrangement of bottles, boxes, etc., and also to change the center line of the chuck before and after the change. In other words, there is no need to move the center line of the bottles, boxes, etc., so the bottles, boxes, etc. do not fall over during the change of the number of lines, and the various devices in the subsequent process can be easily installed. While this is possible, coupled with this array conversion configuration,
Since it has a direction changing configuration in which only specific chucks of the first and second movable substrates are supported by an eccentric rotation support shaft and rotated in the same direction and at the same angle by a pinion rack cylinder,
The rotating structure is simple and control is easy, and deformed bottles and the like do not come into contact with each other without increasing the mounting interval of the chucks, making it possible to have a compact configuration.
