摘要:
A turret type yarn winder comprising a first detecting means (32) for detecting the arrival of an empty bobbin at a yarn-transfer position (F) and outputting a signal, a second detecting means (46) for detecting the arrival of a traverse guide (5) at one turning point and outputting a signal, a third detecting means (47) for detecting the arrival of the traverse guide (5) at another turning point and outputting a signal and a pneumatic cylinder mechanism (42-45) for axially shifting a yarn traverse cam (4a) momentarily by a predetermined distance, whereby the traverse guide can be traversed while exceeding a yarn holding device (38) on the base end of a bobbin. The respective bobbin chucks (1a, 1b) are driven by a common motor via a respective clutch mechanism (50, 167); the clutch mechanism (50, 167) being selectively maintained at one phase of either a full engagement, half engagement, or disengagement during the path of an orbital motion.
摘要:
A turret type precision winder having a turret disc on which a pair of bobbin chucks are held for carrying a working bobbin and an empty bobbin, respectively. A yarn winding operation is carried out on the working bobbin to form a package while a contact pressure is being applied on the package through a pressure roller. The pressure roller is controlled to be maintained at substantially a fixed position while the bobbin chuck of the working bobbin stepwisely moves away from the pressure roller. A positional relationship between the pressure roller, the bobbin chuck and a swingable member for supporting the pressure roller is defined so that a radial component f.sub.1 of the contact pressure reduces as a package diameter increases.

In a vertically movable elevator group management control apparatus for control of a plurality of transversely shiftable cars among plural shafts, control is done by storing route data with respect to each said car, generating target floor data including a target floor, based on car call data obtained in correspondence with each said car and station call data as obtained correspondingly to each floor, estimating the time taken for said car to reach said target floor, based on at least said route data, said target floor data and said car call data, and assigning a certain car to a certain floor call, based on the estimated arrival time.

An elevator control system which provide a high transportation efficiency and also provides for equalization of service quality between floors when a large number of passengers located at different floors desire transportation to a common particular floor. Passengers waiting at a lower level floor will first be picked up prior to the elevator moving to the upper level floors so that the passengers at the lower levels will also be able to get on the elevator when there is a large number of passengers who wish to go to a particular floor during a particular time of the day.
摘要:
A control system for a group of elevators capable of forming a controlled group of elevators by connecting platform call input/output units and operation control units for each floor to each other via a transmission line system. Platform call input/output units and operation control units are connected to each other via transmission lines of every elevator. All of the operation control units and a group control unit are connected to each other via a transmission line, so that the platform call input/output units are disconnected from the group control unit.
摘要:
In a turret type yarn winder, a contact pressure acting on a roller bail by a yarn package is detected and used for controlling the rotation of a turret disc in accordance with the development of yarn layers on a bobbin so that the contact pressure is maintained at a predetermined value. A roller bail (5) detects a pressure acting thereon from a yarn package by a contact pressure sensor (7). If the detected contact pressure is higher than a target value, the turret disc (1) is driven in the direction to reduce the contact pressure. A driving torque of a motor (11) for driving the turret disc (1) is controlled in the normal/reverse direction by a signal corresponding to a deviation between the detected contact pressure and the target value so that the detected contact pressure coincides with the target value.

A spindle assembly capable of accomplishing a swing movement of a spindle bearing mechanism to a machine frame, an operation of holding bobbins on and releasing bobbins from a spindle, and an operation of actuating a rotation stopping mechanism by a sliding movement of an operation handle.In the spindle assembly according to the present invention, a first support and a second support are secured to a front end of the spindle rotatably supported at the rear end on the spindle cradle. Bobbin holding members are inserted into slits arranged on circumferential portions of the first support and the second support and moved outwardly or inwardly in the radial direction while a rear end of a sliding cylinder attached to an operation handle, which is capable of freely rotating, is inserted into an inside of the first support and engaged with projections of the bobbin holding members. Since the rear end of the sliding cylinder is formed into a conical shape, when the operation handle is drawn out, the bobbin holding members are moved inward in the radial direction, so that the bobbin can be removed from the spindle.A stop operation of the spindle is performed by engaging a frictional piece moved by rods passing through the first support and the second support by the operation handle with a conical gap of a braking cylinder secured to the spindle cradle.
