The component supply device includes a body, a first carrier tape transporter, a second carrier tape transporter, and a controller. The body includes a tape transport path. The first carrier tape transporter transports a carrier tape to a component pickup position. The second carrier tape transporter transports the carrier tape to the first carrier tape transporter. The controller is configured to communicate with the component installation device and control the first carrier tape transporter and the second carrier tape transporter in one operation mode selected from a plurality of operation modes.

A management device that manages a unit including a drum and a long object wound around the drum, the management device includes: a receiver that receives, from a user terminal, a captured image obtained by capturing an image of the unit; and a controller that accesses correspondence data obtained by associating each of image capture results, obtained by successively capturing images of the unit while winding the long object around the drum, with a corresponding winding amount of the long object wound around the drum at a time when the each of the image capture results was obtained. The controller determines a remaining amount of the long object based on the captured image and the correspondence data.

A material tracking system is provided for tracking material stored on and drawn from a reel. The material tracking system may include a reel, detection element, digital logic components, battery and power components, transceiver and communication components, location receiver, enclosure, analytic component and interface component. One or more sensors relative to the reel may detect a position indicative of forward or reverse reel rotation. A processor may analyze signals to count rotations of the reel, which is savable in memory. A battery may provide power. The system may also record the time and location associated with rotations. A method to operate a tracking material stored on and drawn from a reel using the material tracking system is also provided.

An elongated-object drum includes: a drum on which an elongated object is wound; and a management module that is attached to the drum and comprises: an acceleration sensor that detects acceleration of the drum, a computation device that performs computation based on a detection result from the acceleration sensor, and a storage device that stores a computation result obtained by the computation device based on the detection result from the acceleration sensor.

A method and a device for optimal use of windable material during winding up onto and/or unwinding from storage drums operates in conjunction with feeding to winding machines. The windable material can be a textile web, a fabric web, a wire or the like. A counterforce necessary for keeping the tension force acting on the windable material constant is maintained until all of the windable material has been fed into subsequent processing. The counterforce may be maintained by a connecting element that is connected to the windable material and to the storage drum, is able to be wound up, and is of lower quality than the windable material. In the device, controllable means generate the counterforce counteracting the tension force until all of the windable material has been drawn into the subsequent processing device.

A device for depositing material in the form of wire including a coil of wire configured to pivot around an axis of rotation as well as at least one indication system including a support, at least one rod oriented in a direction secant to the axis of rotation, a pad connected to the first end of the rod and configured to bear against a wire wound on the coil of wire, a sliding link configured to allow the rod to translate in the secant direction, as well as a return element configured to translate the rod in the direction of the axis of rotation, the rod occupying a position according to a level of filling the coil. This solution makes it possible to obtain a passive type indication system.

A winding device for winding a yarn onto a package tube has a spindle that holds and rotationally drives the package tube. A support roller abuts against a peripheral surface of the yarn winding package during winding of the yarn. The spindle is supported by a pivotably mounted swivel arm so as to swivel relative to the support roller. A contact-force control device is provided and includes an actuator disposed to actuate the swivel arm, and a control device configured with the actuator. A bending beam load cell is configured on the swivel arm to determine an actual value of a contact force between the yarn package and the support roller. The contact force is regulated to a predetermined target value via control of the actuator by the control device.
