There is provided a manufacturing apparatus for manufacturing a cleaning web member by intermittently cutting a continuous web member at a product pitch in a transport direction, the continuous web member having a base sheet continuous in the transport direction and a fiber bundle placed on and secured to the base sheet with a direction of fibers being along the transport direction. The manufacturing apparatus includes: an intermittent transport mechanism that intermittently transports the continuous web member in the transport direction; a cutter mechanism that is disposed downstream from the intermittent transport mechanism in the transport direction, and that produce a downstream end portion of the continuous web member as the cleaning web member by cutting and separating the downstream end portion from the continuous web member while transport of the continuous web member is suspended; a sensor that measures a displacement amount of a stop position of a predetermined region of the continuous web member from a target stop position, while transport of the continuous web member is suspended, the measurement being performed at a measurement position which is a position upstream from the intermittent transport mechanism in the transport direction; and a control section that controls a transport amount related to the intermittent transport by the intermittent transport mechanism based on information of the displacement amount output from the sensor.

The invention describes a machine (10) for producing bags of flexible material, comprising a reel-holder group (12) that removably supports at least one reel (14, 16) capable of supplying at least one said flexible material, a welding group (18) provided with at least one upper welding plate (20) and at least one corresponding lower welding plate (22) that are heated and provided with corresponding linear welding tracks, such upper (20) and lower (22) welding plates acting on the film according to a vertical alternate movement, pinching it along one or more linear portions, and at least one cutting group (24, 26) that separates from each other the single bags that have just been obtained further to the welding operation on the film. The lower welding plate (22) is made integral with a base (30), whereas the upper welding plate (20) is mobile with an alternate motion along a plurality of vertical guiding columns (32) and is constrained at the top to a plurality of moving means (36, 38) associated with a cover (40) fixed above such vertical guiding columns (32). Each single moving means (36, 38) is controlled by a respective motor (42) integral with the cover (40).
摘要:
A sealing unit for sealing and forming a packaging container is disclosed. The sealing unit operates on a principle that the motion of a pair of opposing sealing jaws is controlled by means of a cam-cam follower interaction combined with the action of a servomotor driving a cam wheel. The invention also concerns a method for calibrating a sealing unit.

In a lateral sealing mechanism (17), a cylindrical film (Fm) is sandwiched and ultrasonic sealing is performed along a direction that intersects a conveying direction while a first horn (51a) and a first anvil (51b), and a second horn (52b) and a second anvil (52a) rotate. The first horn (51a) is mounted on a first rotating body (50a) in a state of being coupled to a plurality of vibrating elements (511). The second horn (52b) is mounted on the second rotating body (50b) in a state coupled to a plurality of vibrating elements (521). A securing member grips a horn unit, which includes the horns and the plurality of vibrating elements, on the forward and rearward sides in the direction of rotation of the horn assembly in the vicinity of the node of ultrasonic vibration and secures the horn unit to the first rotating body (50a) and the second rotating body (50b), respectively.

An ultrasonic welding method includes the acts of pressing an ultrasonic welding stack mounted for linear movement against a first workpiece using an electrical servo motor, applying a predetermined initial load to the first workpiece, and initiating a weld, the initiating of the weld comprising outputting energy from the ultrasonic welding stack to the first workpiece. The method further includes sensing, with at least one sensor, a control variable, outputting a signal corresponding to the sensed control variable to a controller, simultaneously outputting energy from the ultrasonic welding stack to the first workpiece and maintaining a weld distance at or near zero until the signal corresponding to the sensed control variable satisfies a predetermined condition, and applying a controlled force, speed, or a combination of force and speed to said first workpiece with an electrically powered linear actuator to urge said first workpiece against a second workpiece to which said first workpiece is to be joined following satisfaction of said predetermined condition.

摘要:
In accordance with the present invention, there is provided a method of automatically verifying the acceptable insertion of at least one Z-pin (20) into a composite laminate (24). The method comprises the initial step of positioning at least one Z-pin (20) upon the composite laminate (24). Thereafter, an insertion force is applied to the Z-pin (20) at a first level which is sufficient to commence an insertion process wherein the Z-pin (20) is driven into the composite laminate (24) at a first insertion speed. The insertion force applied to the Z-pin (20) is continuously monitored, with the first insertion speed being reduced to a second insertion speed in response to a monitored increase in the insertion force from a first level to a second level. The application of the insertion force to the Z-pin (20) is discontinued and the insertion process terminated in response to a monitored increase in the insertion force from the second level to a third level. To confirm an acceptable insertion, the reduction from the first insertion speed to the second insertion speed is verified, as is the increase of the insertion force to the third level.
