Description

Safety clutch for rotary conveyor used in facilities that automatically manufacture water purifiers

The present invention relates to a safety clutch for a vacuum device, and more specifically, to a safety for a rotary vacuum device in an automated manufacturing facility in which safety accidents that may occur during operation are prevented in advance and the refrigerant tank vacuum operation of a cold/hot water purifier is efficiently performed. It's about the clutch.

In general, in order to manufacture home appliances such as water purifiers, hot/cold water purifiers, and hot/cold water purifiers, facilities are built so that they can be produced by assembling accessory parts by a worker or a robot arm while moving along the continuously provided Kenbeyer facility.

And, the cold/hot water machine or cold/hot water purifier (hereinafter, the name is unified as cold/hot water purifier) includes a cooling device and a heating device to provide cold water and hot water. It is possible to cool the supplied water by circulating the refrigerant.

In particular, the compressor includes a refrigerant tank capable of accommodating the compressed refrigerant, and in a facility for manufacturing a hot/cold water purifier, a refrigerant is introduced into the refrigerant tank by a line-connected vacuum pump while moving the cold/hot water purifier along the Kenbeyer facility. To do this, a vacuum operation was performed on the refrigerant tank.

However, since the vacuum pump has to move along with the cold and hot water purifier along with the movement of the cold and hot water purifier as the hot and cold water purifier is moved along the kenbeier equipment and vacuum work has to be performed for a predetermined period of time, the equipment needs to be expanded unnecessarily. There is a problem in that the equipment cost increases.

In addition, since an operator must manually connect or disconnect the connector connecting the refrigerant tank and the vacuum pump during the movement process, there is a problem in that work efficiency is lowered.

In order to solve the above problems, the present invention installs a safety clutch on a drive shaft of a driving unit that rotates a turntable to prevent safety accidents that may occur during operation, and also to efficiently vacuum the refrigerant tank of a cold/hot water purifier. An object of the present invention is to provide a safety clutch for a rotary vacuum device of an automated water purifier manufacturing facility.

In order to achieve the above object, a safety clutch for a rotary vacuum device of an automated cold/hot water purifier manufacturing facility of the present invention includes: a base including a rotary shaft and a driving unit for inducing rotation of the rotary shaft; a turntable that is rotatably installed on the upper part of the base and includes a rotating plate for seating a plurality of hot and cold water purifiers at regular intervals and a vacuum pump for creating a vacuum in the refrigerant tank of the cold and hot water purifier seated on the rotating plate; a sensor unit chain-connected to the drive shaft of the driving unit to detect a rotation angle of the turntable and transmit a signal to the control unit; A clutch comprising a clutch cylinder installed on the drive shaft, a clutch piston installed so as to be able to ascend and descend between the clutch cylinder and the drive shaft, and a clutch mill plate installed on an upper surface of the clutch piston is installed on the lower surface of the drive gear, It is composed of a clutch disk having a plurality of clutch grooves, an intermediate plate installed on the drive shaft and having gripping holes, and a clutch comprising a clutch ball disposed between the clutch mill plate and the gripping holes of the intermediate plate.

Therefore, the safety clutch for the rotary vacuum device of the automatic cold and hot water purifier manufacturing facility of the present invention installs the safety clutch on the drive shaft of the driving unit that rotates the turntable to prevent safety accidents that may occur during work, and also the refrigerant tank of the cold and hot water purifier. There is an effect that the vacuum operation is performed efficiently.
