Problems solved by technology
[0003] However, when a container filled with low-temperature milk or the like is used as a workpiece, dew may condense on the surface of the workpiece, and moisture may also adhere to the drive roller, causing the drive roller to run idly.
In addition, when a rotary positioning device is used to irradiate the printing part of the container with laser light to print, there are cases where the toner adheres due to the laser light irradiation and the driving roller may run idly.
Therefore, there are cases where correct rotational positioning cannot be performed

Embodiment Construction
[0032] Preferred Mode for Carrying Out the Invention
[0033] Next, embodiments of the rotation positioning device according to the present invention will be described in detail based on the drawings.
[0034] exist Figure 1 ~ Figure 3 Among them, reference numeral 10 is the rotary positioning device of the present invention, and is a rotary positioning device used for irradiating the printing part of the workpiece (container) 14 with laser light for printing. The rotary positioning device 10 is a rotary positioning device that rotates the workpieces 14 arranged at constant intervals and transported by the conveyor 12 around the vertical central axis C to orient in a certain direction. The rotary positioning device 10 is equipped with a gripping assembly 18 that grips the workpiece 14 and transports it to the conveying direction of the conveyor 12; a rotating assembly 20 that rotates the driving roller 46 that is in contact with the gripped workpiece 14 to rotate the workpie...

Disclosed is a rotational positioning device which is capable of eliminating the idling of a driving roller to perform accurate rotational positioning. Specifically disclosed is a rotational positioning device (10) which is provided with a gripping means (18) for gripping and transporting workpieces (14) to the transporting direction of a conveyor (12), rotating means (20) for rotating the workpieces (14) around a vertical axis (C) by rotating driving rollers (46) brought into contact with the gripped workpieces (14), a stop means (22) for stopping the rotated workpieces (14) when the rotated workpieces (14) face toward a certain direction, and cleaning means (60) for cleaning the driving rollers (46), and which is configured in such a manner that the rotating means (20) and the stop means (22) perform the rotational positioning of the workpieces (14) when the gripping means (18) grips and transports the workpieces (14) to the transporting direction of the conveyor (12).
Description
technical field [0001] The present invention relates to a rotary positioning device that rotates workpieces such as containers arranged at constant intervals and transported by a conveyor around a vertical central axis so as to face in a predetermined direction. Background technique [0002] Conventionally, a rotary positioning device has been proposed that rotates a plurality of workpieces transported at regular intervals on a conveyor around a vertical rotation axis to a certain direction (for example, see Patent Document 1 and Patent Document 2). This rotary positioning device is equipped with a holding unit for holding a plurality of workpieces arranged at a certain interval by rollers; a rotating unit for rotating the plurality of workpieces held around a vertical central axis; and a stopper for stopping the rotating workpieces when they face a certain direction. components. In this rotary positioning device, as a rotary unit that rotates the workpiece around a vertica...
