Despite the above provisions, the design of the connection between the scale member (830) and the lifting member (410) is not limited to the embodiment illustrated here, but any generally with equivalent functionality. A known design may be used.
Furthermore, the scale member (830) can be provided with a scale that can be read by the encoder (820) described above. For example, a scale can be attached to the micrometer unit. In this way, the travel distance of the lifting device (400) can be measured and controlled on a micrometer scale. Therefore, accurate motion control can be performed.

  The configuration of the scale member (830) is not limited to a specific design, and may be any known design that can measure the moving distance of the lifting device (400) by connecting to the encoder (820) described above.

With this configuration, as shown in FIGS. 6 and 7, when the elevating member (410) moves up and down, the scale member (830) moves up or down together with the elevating member (410) of the elevating device (400). it can. The encoder (820) can measure the moving distance of the scale member (830) and determine the moving distance of the lifting member (410) of the lifting device (400). For example, the encoder (820) can measure the moving distance of the lifting member (410) of the lifting device (400) by reading the scale of the scale member (830).

  Further, as shown in the embodiment of FIGS. 8 and 9, when the lifting device (10) is configured using one or a plurality of lifting modules (100) according to the present invention, the height of the lifting chuck (30) is increased. The height can be controlled by the vertical movement of the elevating member (410) of the elevating module (100). Further, the height of the encoder (820) can be adjusted by a manual adjustment unit (810) such that the position of the elevating member (410) of the elevating module (100) is the zero position of the scale member (830). As a result, the height of the lifting chuck (30) can be realized by mounting the lifting chuck (30) on the lifting member (420) of the lifting module (100) without any special adjustment.

Therefore, the lifting device (400) can be protected from dropping due to its own weight even if the driving device (500) is broken.

  In order to clamp the clamp member (932), the clamp unit (930), for example, releases the clamp member (932) when compressed air is supplied and releases the clamp member (932) when compressed air is not supplied. It can be configured to clamp. However, the configuration of the clamp unit (930) is not limited to the embodiment exemplified here, and the fall detection sensor (910, 920) is used to detect the fall of the lifting device (400) due to its own weight, and the lifting and lowering is performed.
