Abstract
In a weighing and labelling system for a product, a suction unit (35) having its lower surface carrying a label (Z) is lowered by a drive motor (25) and, immediately before the suction unit (35) is brought into contact with a product (Y) to be wrapped, the supply of an electric power to the drive motor (25) is interrupted to allow the label (Z) to be applied to the product (Y) by the effect of an inertia operation and, thereafter, the suction unit (35) is immediately elevated. Alternatively, by the utilization of a servo mechanism, the label (Z) is applied.
Claims7
A labelling method for applying a label to a product by moving a suction head, carrying the label at a lower face of the suction head, downwardly towards the product positioned therebelow, which comprises steps of interrupting a drive of the suction head in an applying direction immediately before the suction head being lowered arrives at a label applying surface of the product to permit the label to be subsequently applied by the effect of an inertia operation, and detecting an upward leap of the suction head in response to a reaction which has occurred at the time of application of the label, and elevating the suction head after this detection.
A labelling apparatus for applying a label to a product by moving a suction head, carrying the label at a lower face of the suction head, downwardly towards the product positioned therebelow, which comprises a drive means for moving the suction head up and down, a descent detecting means for detecting a lowering of the suction head down to a predetermined position, a drive interrupting means for interrupting the drive of the drive means in an applying direction in the event that the lowering of the suction head down to the predetermined position has been detected by the descent detecting means, a reverse detecting means for detecting a upward leap of the suction head when the drive of the drive means is interrupted, and a drive direction reversing means for driving the drive means in a reverse direction in response to a reverse signal fed from the reverse detecting means.
