Patent ID: 8831774

Claim:
A convey control device for a long object, the convey control device comprising: an upstream side conveying unit; a buffer unit; a downstream side conveying unit; a convey control unit configured to perform convey control of the long object; and a driving source configured to drive the upstream side conveying unit and the downstream side conveying unit, wherein the upstream side conveying unit, the buffer unit, and the downstream side conveying unit are arranged along a conveying path of the long object from a conveying direction upstream side to a conveying direction downstream side, wherein the upstream side conveying unit and the downstream side conveying unit sandwiches and conveys the long object, wherein the buffer unit is configured to be hung down by the long object between the upstream side conveying unit and the downstream side conveying unit and to cancel out a loosening amount of the long object with gravity of the buffer unit, wherein the driving source restricts the driving of the upstream side conveying unit and the downstream side conveying unit, wherein the convey control unit includes means for determining a conveying speed of the long object according to conveying speed information of the long object output from a secondary device or a secondary member following the downstream side conveying unit, means for starting the conveying of the long object according to the conveying speed information of the long object after a convey start instruction is output from the secondary device or the secondary member following the downstream side conveying unit, and means for stopping the conveying of the long object according to a convey stop instruction output from the secondary device or the secondary member following the downstream side conveying unit, and wherein the convey control device further comprises a catalyst that includes information sent from the secondary device or the secondary member following the downstream side conveying unit, the catalyst causing the convey control unit to release the restricting of the driving source and to start the convey control of the long object.
