Conveying device of roller body

Abstract

The invention provides a conveying device of a roller body, which is provided with a shifting device used for carrying out handover between a roller body both sides of which are provided with protrusion parts and a retention unit thereof. The shifting device is provided with two core supporting parts, two lifters, two force cells and a controller, wherein the core supporting parts support the protrusion parts; the lifters enable the core supporting parts to lift respectively; the force cells detect loads acting on the respective core supporting parts; and the controller receives the detectionvalues of the loads and controls the lifting of the two lifters respectively. When the roller body in a state of being retained by the retention unit is received, the controller controls the two lifters and enables the core supporting parts positioned below the protrusion parts to lift; after the core supporting parts are controlled to be stopped if the corresponding detection values exceed the specified value, a motion judging whether the detection values are within a specified range or not is carried out; and when the condition that the two lifters are within the specified range is judged, a signal indicating to relieve the retention of the retention unit is output.

Description

technical field [0001] The present invention relates to a conveying device for a drum body such as a raw material drum (formerly a roll), the drum body conveying device has a transfer device for transferring the drum body, receives the drum body at the transfer place of the drum body, and Transport and transfer the received drum body to other places. Background technique [0002] In a gravure printing machine, a laminating machine, or a film coater, etc., a manned transport trolley is used as a conveying device that receives a roll of a film wound into a roll at the delivery point and transfers it to another place, or Unmanned transport vehicles, such as AGV (Automated Guided Vehicle). The stock roll has a hollow core at the center of the roll body, and the core has protrusions protruding from both ends of the roll body. The conveyance device has a transfer device including two core support parts capable of placing the protruding parts on both sides of the raw material dru...
