摘要:
A take-up reel has a diameter equal to or more than 85 times a thickness of a veneer sheet wound thereon and equal to or more than 300 mm so as to be of a curvature of the take-up reel to reduce cracking in parallel to fiber orientations that occurs in winding a veneer sheet after drying on a winding surface of the take-up reel. A veneer reeling apparatus comprises: a take-up reel disposed in a veneer sheet reeling position in a rotatable manner; a drive roller disposed on the lower surface of the take-up reel, transmitting a driving force with a variable speed: a veneer dryer disposed upstream from the veneer sheet reeling position; a conveyor provided between the terminal end of the veneer dryer and the drive roller in the veneer sheet reeling position; and a plurality of thread feeding mechanisms disposed at arbitrary spatial intervals along a length direction of the take-up reel for a veneer sheet, wherein a continuous dried veneer sheet or dried veneer sheets whose sizes are of a constant length or of a length at random are wound on the take-up reel to form a veneer roll with threads as guide by a frictional force of the drive roller. Further, pairs of two overlapping veneer sheets or sets of a pair of two overlapping veneer sheets and a single veneer sheet can be wound on the take-up reel in a composite form.

A winding mechanism for winding a narrower web has a drive shaft with a torque transmitting member fixedly mounted thereon, and a holder rotatably mounted on the drive shaft with a spring disposed around an outer circumferential surface of the holder with cushioning members interposed therebetween. Stoppers are disposed respectively in three chambers defined in the holder. A groove is defined in an inner circumferential surface of a winding core around which the narrower web is wound, and the cushioning members are fitted in the groove. A pressing force of the spring is applied through the stoppers to the winding core which is mounted on the holder.

Methods and systems of controlling transport of film are disclosed. In one embodiment, a method of controlling a supply platter motor in a no-rewind film transport system, comprises receiving take-up platter control signal information from a take-up platter controller, processing the take-up platter control signal information, and controlling the supply platter motor based at least in part on the processed take-up platter control signal information.

In a method for controlling a storage roller for storing sheet-type objects, in particular banknotes, between the wound layers of a belt-type film, which is spooled to and fro between a film drum, which is driven by a first motor and comprises a film reservoir roll, and a winding drum, which is driven by a second motor and stores the sheet-type objects, the tension of the film is controlled to a predefined set value.

Dynamic tension control for tape transported along a tape path between supply and take-up reels, driven by supply and take-up motors, and having tachometers for determining linear speed of the tape. A controller accelerates the tape toward a target speed, initially operating the motors in static acceleration tension control; and if the linear speed of the tape is within a predetermined range of the target tape speed, operating the motors in composite tension control employing static tension control and delta velocity control.

When an elongate film is initially wound around a core, it is wound under a low winding tension command value T1 corresponding to the length of the core. Then, after the tension is progressively increased at a predetermined rate, the elongate film is wound while its tension is gradually lowered from a high winding tension command value T3.
摘要:
In a paper money handling device of the type in which paper money conveying unit, wheel driving unit and reel driving unit are driven to wind a tape between a wheel and a reel and to rewind the tape wound on the wheel to the reel and to deliver paper money, an initial diameter of the reel and a moving speed of the tape are calculated on the basis of the add-up value of pulses generated from an encoder, and the wheel driving unit and the reel driving unit are controlled so that the moving speed so calculated attains a set speed. Jamming is prevented by slightly changing the set speed from the speed of the paper money conveying unit.
摘要:
A film running device which enables the film to run stably, which as a whole is small in size, simple in construction and requires easy maintenance. A long film 1 is delivered from a delivery roll 2. A drive rotor R of the delivery roll incorporates an outer rotor-type electric motor 25M therein, and is rotated by the motor.
