Teaching including adjustment of an inclination of a suction tool with respect to an object is performed in teaching of a suction position of the suction tool. A sticker affixing system includes an articulated robot, a controller, a suction tool attached to a distal end of the articulated robot, a force sensor, and a storage. The controller causes the articulated robot to execute an operation of bringing the suction tool close to a sticker on a release paper in a teaching mode, an operation of adjusting a suction position of the suction tool and an inclination in a traveling direction (roll axis X) of the suction tool in peeling off the sticker based on a signal from the force sensor, and an operation of storing the teaching data including information about the adjusted suction position and the inclination of the suction tool in the storage.

Generation of a wrinkle is prevented when a sticker is affixed to an object. A sticker affixing system includes an articulated robot, a controller configured to control the articulated robot, a suction tool attached to a distal end of the articulated robot, and a force sensor configured to detect force applied to the suction tool. The controller causes the articulated robot to execute: an operation of moving the suction tool holding a sticker along a surface of an object to which the sticker is affixed; and an operation of adjusting an inclination of the suction tool with respect to a traveling direction (roll axis) of the suction tool and the traveling direction of the suction tool based on a signal from the force sensor.

A label vacuum-grip cylinder calibration system comprising an indicator support holder supporting a first indicator and a second indicator. The indicators each have a display face with a display. Projection areas of the display faces project perpendicularly from the display faces. The indicator support holder supports the first indicator and the second indicator such that a first projection area and a second projection area do not overlap and neither the first indicator nor the second indicator obscures either display.

A label rewind machine counts labels on a label roll having an elongated web with labels attached. The rewind machine has an unwind spindle and a rewind spindle, and a first label sensor and a second label sensor. The label roll is placed on the unwind spindle, and the web is threaded through the first and second sensors and attached to the rewind spindle, creating a web path. As the web is drawn along the web path, each sensor detects the presence or absence of a label on the web proximate that sensor and generates an electronic signal. Together, the sensors generate a specific quadrature sequence dictated by the presence of labels on the web. If the detected sequence mimics a selected sequence, the rewind machine records a unitary count of one label. The label count is indexed by one each time the rewind machine detects the selected sequence.

Label application system and method for applying labels to packages of various sizes and shapes, adaptable for use in a wide range of facilities. The system comprises a gripper for retrieving the label, wherein the gripper releasably and minimally contacts the adhesive side of the label. The system further comprises one or more applicators for firmly applying the label to the package. Movement of the gripper and/or applicators is controlled by a servo-actuated delta-type robot.

Controlling application of adhesive on a substrate includes using a gas sensor, obtaining a first sensor signal. The first sensor signal indicates a partial pressure of a gas that arises from a constituent of the adhesive. Based at least in part on this partial pressure, the controller either controls an applicator's delivery of the adhesive to a substrate or causes an error signal indicative of the adhesive's unsuitability for adhesion.

A system for printing and applying labels to a flow of objects, including a labelling unit, an object transporting device, an object detection sensor, and a control unit, wherein the labelling unit comprises a label printing unit for printing labels to be applied to the objects, wherein the object transporting device is transporting individual objects in a random flow to the labelling unit in an object transporting direction, wherein the object detection sensor is arranged upstream the labelling unit and is detecting a position of the objects when they are transported past the object detection sensor towards the labelling unit, wherein two directly after each other transported objects arranged on the object transporting device are separated by a separation distance, wherein the separation distance is calculated by the control unit based on position detection by the object detection sensor of reference points between a preceding object and a directly subsequent object being transported on the object transporting device, wherein the label printing unit if the separation distance is equal to or less than a predetermined first trigger distance value is printing labels to be applied to the objects in a continuous printing mode, wherein the label printing unit if the separation distance is greater than the predetermined first trigger distance value, is printing labels to be applied to the objects in an intermittent printing mode.
