摘要:
A remote adhesive monitoring system is used in connection with adhesive applied to workpieces moving along a production line. A reservoir, pump, and applicator apply the adhesive to the workpieces. A monitor control computer has an associated data processing program. A pump cycle sensor senses pump cycles. An applicator sensor senses when the adhesive is applied to the workpieces. A workpiece sensor senses the workpieces moving along the line. The monitor control uses input from the applicator sensing means and the workpiece sensor to determine an ON time per each workpiece at a predetermined speed. The monitor control uses input from the workpiece sensor and the pump cycle sensor to determine the number of workpieces per pump cycle. The monitor control calculates an ON time to TOTAL time ratio per each workpiece. The monitor control will then calculate an amount of adhesive used for the given ON time to TOTAL time ratio.

Disclosed is an apparatus for manufacturing an absorbent article by performing processing on and discharging an adhesive onto a workpiece related to the absorbent article while conveying the workpiece in a conveying direction. The apparatus includes: a first-reference-signal outputting section that outputs a first reference signal indicating a conveyance amount of the workpiece; a second-reference-signal outputting section that outputs a second reference signal indicating the conveyance amount of the workpiece; a processing device that performs processing on the workpiece on the basis of a drive signal; an adhesive discharging device that discharges the adhesive toward the workpiece on the basis of a discharge signal; and a controller that generates the drive signal and the discharge signal. At the time of manufacturing the absorbent article, the controller generates the drive signal on the basis of the first reference signal output from the first-reference-signal outputting section and outputs the drive signal to the processing device, and the controller also generates the discharge signal on the basis of the first reference signal and outputs the discharge signal to the adhesive discharging device. At the time of inspecting a discharge amount of the adhesive discharged from the adhesive discharging device, the controller generates the discharge signal on the basis of the second reference signal output from the second-reference-signal outputting section and outputs the discharge signal to the adhesive discharging device, and the controller does not output the drive signal to the processing device.

The automated system includes a fluid dispenser having an applicator tip which is used to apply a fluid to an object. A compliance mechanism is utilized to assist in maintaining the applicator tip of the fluid dispenser in contact with the object during the coating operation. A robot can be utilized to advance the object past the applicator tip during the coating operation. The fluid dispenser is mounted on a movable arm to allow the fluid dispenser to be moved or rotated into and away from the position where fluid is applied to the object. The automated system provides a fluid application system that can apply a precise and repeatable layer of fluid to an object. The use of the robot allows larger objects to be easily handled and for the coating process to be done in a rapid fashion. The automated system is flexible and can readily accommodate changes in the object that is to be coated or the configuration of the coating that is to be applied to the object.

Methods for operating a material dispensing system (16). The method includes measuring numerical values of an operating parameter, such as line velocity, material pressure, or material temperature, of the dispensing system to predict a future numerical value of the operating parameter. The predicted numerical value of the operating parameter is used to accurately define a start time, which is measured from the detection of the presence of a workpiece (12) being transported past an applicator of the dispensing system (16), at which to initiate dispensing of the material from the applicator. A calibration procedure is provided for deriving a mathematical relationship used to determine the predicted numerical value of the operating parameter.

A web coating apparatus (20) includes a supply roll (26) of web (22) and a wind-up spindle (68) to coat the web (22) as the web (22) is wound about the wind-up spindle (86). A variable speed pump (108) directs fluid through the coating die (29) at flow rate that is proportional to the speed of advancement of the web (22). The apparatus (20) is particularly useful for coating discrete lengths of orthopedic splinting and casting tape hat is packaged for single patient use.

A sealing gun (31) of a sealing application device for controlling a flowrate of a sealing material in accordance with a magnitude of an input signal is secured to the forward end of an arm of a robot. The strength of a signal being input to the sealing application device (30) is increasingly or decreasingly controlled in conformity with the increasing or decreasing control of a moving speed of the sealing gun. The moving speed (TSA) of the sealing gun is proportional to the flowrate of the sealing material from the sealing gun, so that a width of bead becomes uniform regardless of the moving speed (TSA) of the sealing gun.

A controller for uniformly dispensing fluid onto a substrate in response to movement between the dispensing unit and the substrate has a sensor which senses the rate of relative movement and supplies a signal reflective of the movement to an operation device which in turn generates and supplies a control signal to a regulator. The regulator is positioned in the fluid dispensing system and regulates the flow rate of the fluid to the dispensing unit so that the substrate receives a substantially uniform fluid coating per unit length. The operation device receives the signal from the sensing means and computes the rate of relative movement. The rate of relative movement is then compared to a preselected flow rate signal; and a signal is generated and supplied to the regulator reflective of the comparison between the computed rate of movement and the preselected flow rate signal, so that the flow rate of the fluid varies substantially proportionally to the rate of relative movement between the dispensing unit and the substrate so that the amount of dispensed fluid per unit length of substrate is substantially constant.

A variable discharge width device 100 includes a hollow outer cylindrical part 112 where inside and outside thereof communicate with each other via a discharge port 116, and an inner cylindrical part 130 rotatable inside the outer cylindrical part 112 along a circumferential wall of the outer cylindrical part. The inner cylindrical part 130 can introduce fluid thereinto, and has a circumferential part opening 138 formed in the circumferential wall 136 so that inside and outside of the inner cylindrical part 130 communicate with each other. The circumferential part opening 138 is formed so that an opening width thereof changes in the circumferential direction of the inner cylindrical part. The variable discharge width device 100 is capable of discharging the fluid introduced into the inner cylindrical part 130, from a communicating area 148 formed by intersecting the circumferential part opening 138 and the discharge port 116.
