BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work display alignment device for aligning display parts such as patterns displayed on a work such as a plurality of containers in a predetermined direction.

[0002]

2. Description of the Related Art Conventionally, many containers such as bottles are often integrally packaged in a transparent packaging film,
In this case, it is an important issue how to make it possible to wrap the display on the surface of each container such as a pattern in a predetermined direction with good appearance.

As a conventional device of this type, as shown in FIG. 5, a plurality of mounting bases 66, which are rotatable by a motor 65 as a driving device, are provided on the outer peripheral portion of a rotary table 69, and each mounting base is provided. Display 68 of container 67 placed on 66
A sensor 70 is provided to detect the display unit 68, and the display unit 68 is detected by the sensor 70 when each container 67 rotates.
Stop each motor 65 in 68 predetermined directions,
Alternatively, the positions of the display units are aligned by operating the electromagnetic clutch to connect and disconnect.

[0004]

However, since the above-mentioned conventional apparatus has a structure in which each mounting table 66 is rotated by each motor 65, a plurality of expensive motors 65 corresponding to each mounting table 66 are required. However, there are drawbacks that the cost of the entire apparatus becomes high and the installation space for the motor 65 is required, resulting in an increase in size of the apparatus.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a work display alignment device for reducing the cost and size of the entire device.

[0006]

The technical means taken by the present invention to solve the above-mentioned problems are to rotate a plurality of works 15 and to use a sensor 43 to display a display portion 14 such as a pattern provided on the surface thereof. A rotary table 11 for holding a plurality of workpieces 15 and rotating by a drive device 7, which is a workpiece display alignment device for aligning the display portion 14 of each workpiece 15 at a predetermined position by detecting. The pressing means 35 that can freely come in and out of contact with the workpiece 15 held by the rotary table 11
Is provided with a rotation means 42 that rotates by the rotation of the work piece 15, and the signal of the sensor 43 that detects the display portion 14 of the work piece 15 that is rotated by the holding means 35 causes the work piece 15 and the holding means 35 to separate from each other and stop the work piece 15. The stopping means 20 is provided.

[0007]

In the work position aligning device of the present invention, when the rotary table 11 is rotated by the operation of the driving device 7, the pressing means 35 is rotated by the rotation means 42 so that each pressing means 35 rotates. The pressing means 35 and the work 15 approach each other, the pressing means 35 is pressed against the work 15, and the work 15 rotates by the rotation of the pressing means 35.

When each work 15 is rotated, the sensor 43 detects the display portion 14 such as the pattern of the work 15 and operates the stop means 20 by the signal, and the stop means 20 separates the work 15 and the pressing means 35 from each other. Then, the work 15 is stopped at a predetermined rotation position. Therefore, the respective works 15 are individually positioned, and the display portions 14 of the respective works 15 are aligned at the same position.

When the tray 17 is lowered, the container 15 is separated from the pressing body 38 and the rotational force is removed, and then the tray 17 is brought into contact with the opening edge 11a of the rotary table 11. Therefore, the tray 17 on which the container 15 is placed is restricted from rotating and stops,
14 can be positioned in a predetermined direction. This display
The positioning of 14 is ensured individually in each container 15.

Furthermore, three containers each positioned
When 15 is conveyed to the side of the conveyance device 47 via the rotary table 11, the pusher 45 moves forward by the operation of the cylinder 48 to supply the three containers 15 to the conveyance device 47 integrally, and the next step Transport to packaging process.

FIG. 4 shows another embodiment of the present invention. In the above embodiment, the pressing means 35 was rotated by the pulley and the belt, but in this embodiment, the planetary gear mechanism is adopted. is there. That is, the sun pulley 22 is attached to the rotary shaft 1.
Instead of the above, a sun gear 22a is provided, and a planetary gear 53 is provided between the sun gear 22a and the gear 52 formed on the two holding means 35.
Is intervening.

The present invention is not limited to the above-mentioned embodiment, and for example, in the above-mentioned embodiment, the container 15 is used as a work.
However, it is needless to say that it may be an article other than the container.

Further, the raising / lowering mechanism of the tray 17 may be a rack, a pinion mechanism, a cam mechanism or the like other than the cylinder device 20. Moreover, the saucer 17 is provided so as to be rotatable only without moving up and down, and the holding means 35 side can be moved or the saucer 17 can be moved.
It is also possible to move both 17 and the pressing means 35. The display unit 14 for detecting the sensor 43 may be a specific portion of the design drawn on the bottle 13 or may be provided only for detection.

[0025]

As described above, the container display alignment apparatus of the present invention holds a plurality of works and is rotated by a drive unit, and a pressing means capable of contacting and separating the works held on the turntable. Is provided with a rotation means for rotating by rotation of the rotary table, and a stop means for separating the work and the holding means and stopping the work by a signal of the sensor that detects the display portion of the work rotated by the holding means. Since it is provided, each pressing means can be rotated by utilizing the rotation of the rotary table.

Therefore, the number of drive devices such as motors can be reduced as compared with the conventional one in which a motor is provided for each work, the cost of the device can be reduced, and each drive can be performed. Since the installation space for the device is not required, it is possible to downsize the device.
