methods for applying glutinous substances

BACKGROUND

Glutinous substances, such as sealants, adhesives, and fillers, are applied onto surfaces of structures or other objects for purposes of sealing, corrosion resistance, and/or fixation, among others. Various manual tools for application of glutinous substances are commercially available. However, manual application of glutinous substances is labor-intensive, time-consuming, and difficult to control to a precise tolerance.

SUMMARY

Accordingly, apparatuses and methods, intended to address at least the above-identified concerns, would find utility.

The following is a non-exhaustive list of examples, which may or may not be claimed, of the subject matter according to the present disclosure.

One example of the subject matter according to the present disclosure relates to an apparatus for delivering a glutinous substance from a cartridge to an applicator. The apparatus comprises a sleeve, comprising a central axis, an inlet, and an outlet opposite the inlet. The sleeve is configured to receive the cartridge through the inlet. The apparatus also comprises a pressure-cap assembly, coupled to the sleeve and comprising a pressure cap, proximate the inlet of the sleeve. With the cartridge received within the sleeve, the pressure cap is movable between, inclusively, a closed position, in which the pressure cap is in sealed engagement with a trailing end of the cartridge, and an open position, in which the pressure cap provides clearance sufficient for insertion of the cartridge inside the sleeve through the inlet of the sleeve. The pressure cap comprises a first pressure input, through which pressure is selectively applied to the glutinous substance in the cartridge when the cartridge is received within the sleeve, the pressure cap is in the closed position, and a leading end of the cartridge is in sealed engagement with the applicator. The pressure-cap assembly further comprises an actuator, coupled to the pressure cap and to the sleeve. The actuator is selectively operable to move the pressure cap relative to the sleeve between, inclusively, the closed position and the open position. The apparatus further comprises an automated coupler, configured to automatically reversibly sealingly couple the applicator with the leading end of the cartridge when the cartridge is inside the sleeve and the pressure cap is in the closed position.

Another example of the subject matter according to the present disclosure relates to a system for delivering a glutinous substance from a cartridge to a surface of a workpiece. The system comprises an applicator, configured to be reversibly sealingly coupled with a leading end of the cartridge. The system further comprises a robot, comprising a tool interface. Additionally, the system comprises an apparatus, comprising a robot interface, configured to be coupled to the tool interface of the robot. The apparatus also comprises a sleeve, comprising a central axis, an inlet, and an outlet opposite an inlet. The sleeve is configured to receive the cartridge through the inlet. The apparatus further comprises a pressure-cap assembly, coupled to the sleeve and comprising a pressure cap. The pressure cap is proximate the inlet of the sleeve. With the cartridge received within the sleeve, the pressure cap is movable between, inclusively, a closed position, in which the pressure cap is in sealed engagement with a trailing end of the cartridge, and an open position, in which the pressure cap provides clearance sufficient for insertion of the cartridge inside the sleeve through the inlet of the sleeve. The pressure cap comprises a first pressure input, through which pressure is selectively applied to the glutinous substance in the cartridge when the cartridge is received within the sleeve, the pressure cap is in the closed position, and the leading end of the cartridge is in sealed engagement with the applicator. Additionally, the pressure-cap assembly comprises an actuator, coupled to the pressure cap and to the sleeve. The actuator is selectively operable to move the pressure cap relative to the sleeve between, inclusively, the closed position and the open position. The apparatus also comprises an automated coupler, configured to automatically reversibly sealingly couple the applicator with the leading end of the cartridge when the cartridge is inside the sleeve and the pressure cap is in the closed position. The system further comprises a controller, operatively coupled with the robot and the apparatus.

Yet another example of the subject matter according to the present disclosure relates to a method of delivering a glutinous substance from a cartridge to an applicator. The method comprises receiving the cartridge inside a sleeve through an inlet of the sleeve when a pressure cap, coupled to the sleeve proximate the inlet, is in an open position. The cartridge has a leading end and a trailing end. The method also comprises moving the pressure cap into a closed position to sealingly couple the pressure cap with the trailing end of the cartridge. Additionally, the method comprises selectively causing an automated coupler to automatically sealingly couple the applicator with the leading end of the cartridge when the cartridge is inside the sleeve and the pressure cap is in the closed position. The method further comprises applying pressure to the glutinous substance in the cartridge through a first pressure input of the pressure cap to urge the glutinous substance from the cartridge into the applicator.

Illustrative, non-exhaustive examples, which may or may not be claimed, of the subject matter according the present disclosure are provided below.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-5 and 15, apparatus 102 for delivering glutinous substance 168 from cartridge 166 to applicator 254 is disclosed. Apparatus 102 comprises sleeve 106, comprising central axis 121, inlet 124, and outlet 128 opposite inlet 124. Sleeve 106 is configured to receive cartridge 166 through inlet 124. Apparatus 102 also comprises pressure-cap assembly 104, coupled to sleeve 106. Pressure-cap assembly 104 comprises pressure cap 110, proximate inlet 124 of sleeve 106. With cartridge 166 received within sleeve 106, pressure cap 110 is movable between, inclusively, a closed position, in which pressure cap 110 is in sealed engagement with trailing end 169 of cartridge 166, and an open position, in which pressure cap 110 provides clearance sufficient for insertion of cartridge 166 inside sleeve 106 through inlet 124 of sleeve 106. Pressure cap 110 comprises first pressure input 118, through which pressure is selectively applied to glutinous substance 168 in cartridge 166 when cartridge 166 is received within sleeve 106, pressure cap 110 is in the closed position, and leading end 167 of cartridge 166 is in sealed engagement with applicator 254. Pressure-cap assembly 104 further comprises actuator 114, coupled to pressure cap 110 and to sleeve 106. Actuator 114 is selectively operable to move pressure cap 110 relative to sleeve 106 between, inclusively, the closed position and the open position. Apparatus 102 further comprises automated coupler 223, configured to automatically reversibly sealingly couple applicator 254 with leading end 167 of cartridge 166 when cartridge 166 is inside sleeve 106 and pressure cap 110 is in the closed position. The preceding subject matter of this paragraph characterizes example 1 of the present disclosure.

Apparatus 102 is configured to facilitate a reduction in the labor, time, and inaccuracies associated with the application of glutinous substances onto surfaces of workpieces. Cartridge 166 of apparatus 102 provides modular containment of glutinous substance 168. Sleeve 106 of apparatus 102 enables a secure coupling of cartridge 166 to apparatus 102. Pressure-cap assembly 104 allows both access to sleeve 106 for the insertion of cartridge 166 into sleeve 106 and the application of pressure to cartridge 166 for urging glutinous substance 168 out of sleeve 106. Actuator 114 facilitates automated actuation of pressure-cap assembly 104. With cartridge 166 received within sleeve 106 and pressure cap 110 in a closed position, cartridge 166 is sealed with applicator 154 to enable sealed flow of glutinous substance 168 from cartridge 166 to applicator 154 via the application of pressure to glutinous substance 168 in cartridge 166. Automated coupler 223 facilitates quick automated coupling of applicator 254 with apparatus 102 and quick automated releasing of applicator 254 from apparatus 102. As used herein, a first object is reversibly coupleable to a second object when the first object can be repeatedly coupled to the second object and decoupled from the second object without permanent deformation of, damage to, or destruction of either the first object or the second object.

Apparatus 102 can include pressure tubes 138, 267A, 269A, 267B, 269B to facilitate the communication of pressure to and from various components of apparatus 102. For example, pressure tubes 138 may communicate pressure to pressure inputs 118. As an example, pressure tubes 138 may communicate pressure to and from actuator 114 to facilitate selective operation of actuator 114. Also, pressure tubes 138 may communicate pressure to second and third pressure inputs 238, 240 to control operation of automated coupler 223 and to sixth and seventh pressure inputs 214, 216 to control operation of sleeve interface 200 of contact regulator 201. Furthermore, one or more pressure tubes 138 may communicate pressure to eighth pressure inputs 274 to control operation of biasing mechanisms 217. According to yet another example, pressure tubes 267A, 269A can communicate pressure to fourth and fifth pressure inputs 290A, 292A and pressure tubes 267B, 269B can communicate pressure to first and second pressure outputs 290B, 292B to control operation of applicator 254.

In some examples, various components of apparatus 102 are fixed to sleeve 106 via clamps 116, 132, 150. For example, actuator 114 is fixed to sleeve 106 by clamp 116 and brackets 148 are fixed to sleeve 106 by clamps 132, 150. According to other examples, the various components of apparatus 102 are fixed to sleeve 106 using other fixation techniques, such as fastening, adhering, co-forming, and the like.

Actuator 114 can be any of various actuators known in the art, such as linear actuators and rotary actuators, powered in any of various ways, such as pneumatically, electromagnetically, electrically, hydraulically, and the like. Pressure inputs 118, 214, 216, 238, 240, 274, 290A, 292A and pressure outputs 290B, 292B, can be pneumatic fittings in some examples. As used herein, a central axis of an object is a longitudinal symmetry axis of the object.

As defined herein, an object that is movable between, inclusively, two positions means the object can be moved into the two positions.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-5 and 15, the pressure, selectively applied to glutinous substance 168 in cartridge 166 through first pressure input 118 of pressure cap 110 is pneumatic pressure. The preceding subject matter of this paragraph characterizes example 2 of the present disclosure, wherein example 2 also includes the subject matter according to example 1, above.

Selective introduction of pneumatic pressure to first pressure input 118 of pressure cap 110 enables precise application of pneumatic pressure to glutinous substance 168 in cartridge 166 to precisely control the flow of glutinous substance 168 out of cartridge 166 and into applicator 154. Moreover, selective introduction of pneumatic pressure to first pressure input 118 of pressure cap 110 facilitates the use of automated pneumatic controls to control the pneumatic operation of first pressure input 118 of pressure cap 110.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIG. 4, pressure cap 110 further comprises gasket 111, configured to form a seal between pressure cap 110 and interior surface 113 of cartridge 166 when pressure cap 110 is in the closed position and applicator 254 is coupled with leading end 167 of cartridge 166. The preceding subject matter of this paragraph characterizes example 3 of the present disclosure, wherein example 3 also includes the subject matter according to any one of examples 1 or 2, above.

Gasket 111, by forming seal between pressure cap 110 and interior surface 113 of cartridge 166, facilitates the containment of pressure from first pressure input 118 of pressure cap 110 to within cartridge 166.

Gasket 111 can be an o-ring made from a pliable or compressible material, such as rubber, silicone, and plastic polymers.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-4 and 15, pressure-cap assembly 104 further comprises arm 115, pivotable about axis 117 that is fixed relative to sleeve 106 and is perpendicular to central axis 121 of sleeve 106. Pressure cap 110 is coupled with arm 115. The preceding subject matter of this paragraph characterizes example 4 of the present disclosure, wherein example 4 also includes the subject matter according to any one of examples 1-3, above.

Arm 115, being pivotable about axis 117 that is fixed relative to sleeve 106 and is perpendicular to central axis 121 of sleeve 106, enables pressure cap 110 to be moved between the closed position, to sealingly engage trailing end 169 of cartridge 166, and the open position, to provide clearance sufficient for insertion of cartridge 166 inside sleeve 106 through inlet 124 of sleeve 106 and ejection of cartridge 166 from sleeve 106. In other words, arm 115 allows pressure cap 110 to be pivoted into sealed engagement with cartridge 166 and pivoted away from cartridge 166 to allow cartridge 166 to be inserted into or removed from sleeve 106.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-4 and 15, pressure-cap assembly 104 further comprises first lock mechanism 112, mechanically coupling arm 115 with actuator 114. First lock mechanism 112 is configured to releasably lock pressure cap 110 in the closed position by releasably locking arm 115 relative to sleeve 106. The preceding subject matter of this paragraph characterizes example 5 of the present disclosure, wherein example 5 also includes the subject matter according to example 4, above.

Using first lock mechanism 112 to releasably lock pressure cap 110 in the closed position by releasably locking arm 115 relative to sleeve 106 prevents disengagement between pressure cap 110 and cartridge 166 should actuator 114 fail. In other words, in the event actuator 114 fails to urge pressure cap 110 in closed position, such as due to loss of pressure to or malfunction of actuator 114, while pressure is applied to glutinous substance 168 in cartridge 166, first lock mechanism 112 locks pressure cap 110 in the closed position to prevent pressure within cartridge 116 from inadvertently moving pressure cap 110 out of the closed position.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., 2-4 and 15, actuator 114 is selectively operable to move first lock mechanism 112 between, inclusively, a locked position, in which arm 115 is releasably locked relative to sleeve 106 so pressure cap 110 is releasably locked in the closed position, and an unlocked position, in which arm 115 is arranged relative to sleeve 106 so that pressure cap 110 is in the open position. The preceding subject matter of this paragraph characterizes example 6 of the present disclosure, wherein example 6 also includes the subject matter according to example 5, above.

Actuator 114 is configured to enable first lock mechanism 112 to unlock pressure cap 110 and allow pressure cap 110 to move out of the closed position by moving first lock mechanism 112 relative to arm 115, via selective operation of actuator 114, while pressure cap 110 is sealingly engaged with cartridge 166. In other words, first lock mechanism 112 in the locked position will lock pressure cap 110 in the closed position until actuator 114 moves first lock mechanism 112 relative to pressure cap 110 to unlock first lock mechanism 112 and move pressure cap 110 into the open position.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-4 and 15, actuator 114 is pneumatically operable. When first lock mechanism 112 is in the locked position, first lock mechanism 112 is configured to remain in the locked position if actuator 114 loses pressure. The preceding subject matter of this paragraph characterizes example 7 of the present disclosure, wherein example 7 also includes the subject matter according to example 6, above.

In the event actuator 114 loses pressure, while pressure is applied to glutinous substance 168 in cartridge 166, first lock mechanism 112 locks pressure cap 110 in the closed position to prevent pressure within cartridge 116 from inadvertently moving pressure cap 110 out of the closed position.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-4 and 15, first lock mechanism 112 comprises an over-center linkage. The preceding subject matter of this paragraph characterizes example 8 of the present disclosure, wherein example 8 also includes the subject matter according to any one of examples 5-7, above.

The over-center linkage of first lock mechanism 112 enables quick, easy, and effective locking and unlocking of the lock mechanism.

The over-center linkage can be a passive lock mechanism that is simply constructed, yet effective at preventing backdriving. For example, the over-center linkage includes first and second linkages each independently pivotable about the same first axis. The first linkage is pivotally fixed to arm 115 and pivots about a second axis. The second linkage is pivotally fixed relative to sleeve 106 and pivots about a third axis. As arm 115 rotates to move pressure cap 110 toward closed position, the first linkage rotates about the first axis in a first rotational direction and the second linkage rotates about the first axis in a second rotational direction opposite the first rotational direction until the first, second, and third axes are aligned, which positions the over-center linkage in an over-center position. Further rotation of arm 115 to move pressure cap 110 into the closed position results in the over-center linkage moving beyond the over-center position, which locks arm 115 and prevents arm 115 from rotating pressure cap 110 toward the open position. The over-center linkage is unlocked to allow arm 115 to rotate pressure cap 110 toward the open position by concurrently pivoting, via actuator 114, the first linkage about the first axis in the second rotational direction and pivoting the second linkage about the first axis in the first rotational direction until the over-center linkage moves into and beyond the over-center position.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2, 3, and 15, pressure cap 110 is pivotable relative to arm 115. Pressure-cap assembly 104 further comprises biasing element 122, configured to torsionally bias pressure cap 110 relative to arm 115. The preceding subject matter of this paragraph characterizes example 9 of the present disclosure, wherein example 9 also includes the subject matter according to any one examples 4-8, above.

Because arm 115, to which pressure cap 110 is coupled, rotates to move pressure cap 110 into the closed positioned, in sealed engagement with trailing end 169 of cartridge 166, enabling pressure cap 110 to pivot relative to arm 115 allows pressure cap 110 to maintain coaxial alignment with trailing end 169 of cartridge 166 as arm 115 rotates. By torsionally biasing pressure cap 110, biasing element 122 ensures pressure cap 110 is coaxially aligned with trailing end 169 of cartridge 166 as pressure cap 110 initially engages trailing end 169 of cartridge 166. In this manner, pressure cap 110 can properly engage and seat within trailing end 169 of cartridge 166 without binding with or crookedly entering trailing end 169 of cartridge 166. As used herein, to “torsionally bias” means to continuously apply a moment, which may or may not have a constant magnitude, but is always applied in the same direction and has a magnitude greater than zero.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2, 3, and 15, biasing element 122 comprises a torsion spring. The preceding subject matter of this paragraph characterizes example 10 of the present disclosure, wherein example 10 also includes the subject matter according to example 9, above.

A torsion spring facilitates a passive and simple way to torsionally bias pressure cap 110 relative to arm 115.

The torsion spring can be coupled at one end to arm 115 and at another end to pressure cap 110. In some examples, the torsion spring includes a coiled or twisted torsion bar that biases one end of the torsion spring relative to the other end of the torsion spring.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 3 and 15, apparatus 102 further comprises control valve 180, pneumatically coupled to first pressure input 118 of pressure cap 110 and to actuator 114. Control valve 180 is configured to disable operation of actuator 114 by preventing pressure from being communicated to actuator 114 when, with pressure cap 110 in the closed position, pressure is applied to glutinous substance 168 in cartridge 166 through first pressure input 118. The preceding subject matter of this paragraph characterizes example 11 of the present disclosure, wherein example 11 also includes the subject matter according to any one of examples 1-10, above.

Control valve 180 prevents actuator 114 from inadvertently opening pressure cap 110 while pressure is being applied to glutinous substance 168 in cartridge 166 through first pressure input 118. Preventing pressure cap 110 from opening while pressure is being applied to glutinous substance 168 due to inadvertent actuation of actuator 114 ensures pressure within cartridge 166 is not inadvertently released.

In some examples, control valve 180 is a two-way, normally open, air-piloted valve manufactured, e.g., by Clippard Instrument Laboratory, Inc. of Cincinnati, Ohio.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2, 3, 5, and 17, apparatus 102 further comprises sensor 256, configured to be coupled to applicator 254. The preceding subject matter of this paragraph characterizes example 12 of the present disclosure, wherein example 12 also includes the subject matter according to any one of examples 1-11, above.

Sensor 256 enables detection of one or more characteristics of glutinous substance 168 in applicator 254. The characteristics of glutinous substance 168 in applicator 254 detected by sensor 256 can be used to control the rate at which glutinous substance 168 flows from cartridge 166 to applicator 254. Additionally, the characteristics of glutinous substance 168 in applicator 254 detected by sensor 256 can be used to control applicator 254 to regulate the rate at which glutinous substance 168 flows from applicator 254 to surface 172 of workpiece 170. Further, in some examples, sensor 256 being configured to be coupled to applicator 254 allows pressure sensor 158 to remain part of applicator 254 as applicator 254 is coupled to and decoupled from apparatus 102 via selective operation of automated coupler 223.

According to some examples, sensor 256 is a pressure sensor, a temperature sensor, a combination pressure-temperature sensor, or two sensors (one pressure and one temperature).

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2, 3, 5, and 17, sensor 256 is a pressure sensor. The preceding subject matter of this paragraph characterizes example 13 of the present disclosure, wherein example 13 also includes the subject matter according to example 12, above.

The pressure sensor enables detection of the pressure of glutinous substance 168 in applicator 154. The pressure of glutinous substance 168 in applicator 154, detected by the pressure sensor, can be used to control the rate at which glutinous substance 168 flows from cartridge 166 to applicator 154. Additionally, the pressure of glutinous substance 168 in applicator 254 detected by the pressure sensor can be used to control applicator 254 to regulate the rate at which glutinous substance 168 flows from applicator 254 to surface 172 of workpiece 170.

As defined herein, “a limited degree of contact” means a force not exceeding a predetermined threshold, e.g., between applicator 254 and workpiece 170. The predetermined threshold of the force is set low enough to avoid damage to workpiece 170 and applicator 254.

In one example, contact regulator 201 comprises both force-torque sensor 222 and compliant assembly 202. According to such an example, force-torque sensor 222 can be configured to detect a presence or a degree of contact between applicator 254 and surface 172 of workpiece 170 and compliant assembly 202 can be configured to allow movement between applicator 254 and sleeve 106 such that force due to contact between applicator 254 and surface 172 of workpiece 170 is reduced.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-12 and 14-17, contact regulator 201 is further configured to determine at least one of a presence or a degree of the contact between applicator 254 and surface 172 of workpiece 170. The preceding subject matter of this paragraph characterizes example 40 of the present disclosure, wherein example 40 also includes the subject matter according to example 39, above.

Determining at least one of the presence or the degree of contact between applicator 254 and surface 172 of workpiece 170 provides feedback for controlling movement of apparatus 102 to avoid or reduce damage to surface 172 of workpiece 170 or to applicator 254 due to inadvertent impacts between applicator 254 and surface 172 of workpiece 170. For example, when the presence or the degree of contact between applicator 254 and surface 272 of workpiece 170 is determined, apparatus 102 can be controlled to move applicator 254 away from surface 172 of workpiece 170 to limit the contact between applicator 254 and surface 172 of workpiece 170 and avoid damage to surface 172 of workpiece 170 or to applicator 254 or prevent further damage to surface 172 of workpiece 170 or to applicator 254.

In one example, at least one of a presence or a degree of the contact between applicator 254 and surface 172 of workpiece 170 is determined from an output of one or more proximity sensors 210 of compliant assembly 202. According to another example, at least one of a presence or a degree of the contact between applicator 254 and surface 172 of workpiece 170 is determined from an output of force-torque sensor 222.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-12 and 14-17, contact regulator 201 enables the limited degree of contact between applicator 254 and surface 172 of workpiece 170 by communicating a command, descriptive of at least one of the presence or the degree of contact between applicator 254 and surface 172 of workpiece 170, to controller 157, which is configured, based at least in part on the command, to direct robot 152 to move apparatus 102 and applicator 254 relative to surface 172 of workpiece 170. The preceding subject matter of this paragraph characterizes example 41 of the present disclosure, wherein example 41 also includes the subject matter according to example 40, above.

Controller 157, being configured to direct robot 152 to move apparatus 102 and applicator 254 relative to surface 172 of workpiece 170 based at least in part on a command, descriptive of at least one of the presence or the degree of contact between applicator 254 and surface 172 of workpiece 170, facilitates automatic adjustment of the position of apparatus 102 and applicator 254 when the presence or the degree of contact between applicator 254 and surface 172 of workpiece 170 is determined. Robot 152 facilitates programmable, precise, and responsive control (e.g., movement) of apparatus 102 and applicator 254.

In some examples, robot 152 comprises a robotic or mechanical arm. According to yet certain examples, controller 157 comprises a computing device with one or more of software stored in memory or programmable logic hardware, each configured to execute instructions for operation of robot 152 and apparatus 102.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 15 and 16, contact regulator 201 comprises force-torque sensor 222, configured to determine at least one of the presence or the degree of the contact between applicator 254 and surface 172 of workpiece 170 based on at least one of a torque or a force detected by force-torque sensor 222 when applicator 245 contacts surface 172 of workpiece 170. The preceding subject matter of this paragraph characterizes example 42 of the present disclosure, wherein example 42 also includes the subject matter according to example 41, above.

Force-torque sensor 222 enables responsive and precise detection of the presence or the degree of contact between applicator 254 and surface 172 of workpiece 170. Additionally, in some examples, force-torque sensor 222 is programmable to compensate for the force exerted on applicator 254 by glutinous substance 168 as glutinous substance 168 is being delivered to applicator 254.

According to some examples, force-torque sensor 222 can be any of various sensors, configured to sense the torque and/or the force applied to force-torque sensor 222 by an object. In certain examples, force-torque sensor 222 comprises at least one transducer configured to sense loading applied to applicator 254 when applicator 254 is automatically reversibly sealingly coupled with leading end 167 of cartridge 166.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 15 and 16, force-torque sensor 222 is capable of detecting the torque about at least one axis and is capable of detecting the force along at least one axis. The preceding subject matter of this paragraph characterizes example 43 of the present disclosure, wherein example 43 also includes the subject matter according to example 42, above.

Detecting the torque about at least one axis enables force-torque sensor 222 to determine whether contact with surface 172 of workpiece 170 applies a rotational force to applicator 254 about the at least one axis and/or the degree of rotational force applied to applicator 154 about the at least one axis. For example, knowing the presence or the degree of torque applied to applicator 254 by surface 272 of workpiece 170 enables apparatus 102 and applicator 254 to be moved away from surface 172 of workpiece 170 in a direction opposing the applied torque, which may or may not be a direction perpendicular to surface 172 contacting applicator 254, to limit the torque applied to applicator 254 by surface 172 of workpiece 170.

Detecting the force along at least one axis enables force-torque sensor 222 to determine whether contact with surface 172 of workpiece 170 applies a linear force to applicator 254 along the at least one axis and/or the degree of linear force applied to applicator 154 along the at least one axis. For example, knowing the presence or the degree of force applied to applicator 254 by surface 272 of workpiece 170 enables apparatus 102 and applicator 254 to be moved away from surface 172 of workpiece 170 in a direction opposing the applied force to limit the force applied to applicator 254 by surface 172 of workpiece 170.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 15 and 16, force-torque sensor 222 is capable of detecting the torque about three axes and is capable of detecting the force along three axes. The preceding subject matter of this paragraph characterizes example 44 of the present disclosure, wherein example 44 also includes the subject matter according to example 42, above.

Detecting the torque about at least three axes enables force-torque sensor 222 to more precisely determine whether contact with surface 172 of workpiece 170 applies a rotational force to applicator 254 about the at least three axes and/or the degree of rotational force applied to applicator 154 about the at least three axes. For example, knowing the presence or the degree of torque applied to applicator 254 by surface 272 of workpiece 170, about at least three axes, enables apparatus 102 and applicator 254 to be moved away from surface 172 of workpiece 170 in a direction more precisely opposing the applied torque, which may or may not be a direction perpendicular to surface 172 contacting applicator 254, to limit the torque applied to applicator 254 by surface 172 of workpiece 170.

Detecting the force along at least three axes enables force-torque sensor 222 to determine whether contact with surface 172 of workpiece 170 applies a linear force to applicator 254 along the at least three axes and/or the degree of linear force applied to applicator 154 along the at least three axes. For example, knowing the presence or the degree of force applied to applicator 254 by surface 272 of workpiece 170, about the at least three axes, enables apparatus 102 and applicator 254 to be moved away from surface 172 of workpiece 170 in a direction more precisely opposing the applied force to limit the force applied to applicator 254 by surface 172 of workpiece 170.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-12, 14, and 17, contact regulator 201 comprises compliant assembly 202. The preceding subject matter of this paragraph characterizes example 45 of the present disclosure, wherein example 45 also includes the subject matter according to any one of examples 41-44, above.

Compliant assembly 202 facilitates the enablement of a limited degree of contact between applicator 254 and surface 172 of workpiece 170 by allowing biased movement of applicator 254 relative to sleeve 106 when applicator 254 contacts surface 172 of workpiece 170. Biased movement between applicator 254 and sleeve 106 enables applicator 254 to, at least partially, give way upon contacting surface 172 of workpiece 170 such that impact forces imparted to surface 172 by applicator 254 are reduced.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-12, 14, and 17, compliant assembly 202 comprises first portion 204, coupled with sleeve 106, second portion 206, non-movably coupled to automated coupler 223, and at least one biasing mechanism 217, movably coupling second portion 206 with first portion 204 and biasing second portion 206 away from first portion 204 along central axis 121 of sleeve 106. The preceding subject matter of this paragraph characterizes example 46 of the present disclosure, wherein example 46 also includes the subject matter according to example 45, above.

At least one biasing mechanism 217 of compliant assembly 202 facilitates biased movement between applicator 254 and sleeve 106. Non-movably coupling second portion 206 of compliant assembly 202 to automated coupler 223 allows apparatus 102 to both automatically reversibly sealingly couple applicator 254 with leading end 167 of cartridge 166 and enable a limited degree of contact between applicator 254 and surface 172 of workpiece 170.

In some examples, second portion 206 is non-movably coupled to automated coupler 223 via one or more fasteners.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-12, 14, and 17, each of at least one biasing mechanism 217 comprises spring 220 and piston 218. Piston 218 extends through spring 220 and is fixed relative to one of first portion 204 or second portion 206 of compliant assembly 202. Piston 218 is movable relative to another one of first portion 204 or second portion 206 of compliant assembly 202. Each of at least one biasing mechanism 217 also comprises first cylinder 272, movably retaining piston 218. First cylinder 272 is located in one of first portion 204 or second portion 206 of compliant assembly 202. The preceding subject matter of this paragraph characterizes example 47 of the present disclosure, wherein example 47 also includes the subject matter according to example 46, above.

Spring 220, piston 218, and first cylinder 272 of at least one biasing mechanism 217 promote simple, predictable, and reliable biasing of second portion 206 away from first portion 204. Moreover, the limited degree of contact between applicator 254 and surface 172 of workpiece 170 can be at least partially controlled by the stiffness of spring 220.

In one example, spring 220 is a compression spring, configured to impart a biasing force to second portion 206 of compliant assembly 202 that is inversely proportional to a distance between a fixed location on sleeve 106 and surface 172 of workpiece 170 and is less than a magnitude of a force sufficient to damage at least one of applicator 254 or workpiece 170 during a contact therebetween.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 8-10A, 11A, 12, 14, and 17, each of at least one biasing mechanism 217 further comprises eighth pressure input 274, through which regulated pressure is selectively introduced within first cylinder 272. The preceding subject matter of this paragraph characterizes example 48 of the present disclosure, wherein example 48 also includes the subject matter according to example 47, above.

Selective introduction of regulated pressure, through eighth pressure input 274, within first cylinder 272 of biasing mechanism 217, moves piston 218 within first cylinder 272. In other words, introducing regulated pressure within first cylinder 272 of biasing mechanism 217, by selective operation of eighth pressure input 274, pressurizes a portion of first cylinder 272 to cause piston 218 to move along first cylinder 272.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 8-10A, 11A, 12, 14, and 17, the regulated pressure, selectively introduced within first cylinder 272 of each of at least one biasing mechanism 217 via eighth pressure input 274, generates a force equal and opposite to that exerted by glutinous substance 168 on applicator 254 as glutinous substance 168 is delivered from cartridge 166 to applicator 254 and creates a pressure in applicator 254. The preceding subject matter of this paragraph characterizes example 49 of the present disclosure, wherein example 49 also includes the subject matter according to example 48, above.

In some examples, as glutinous substance 168 is delivered from cartridge 166 to applicator 254, glutinous substance 168 may exert pressure on applicator 254, which urges second portion 206 of compliant assembly 202 away from first portion 204 of compliant assembly 202 to effectively immobilize first portion 204 relative to second portion 206. Generating a force in first cylinder 272 equal and opposite to that exerted by glutinous substance 168 on applicator 254, as glutinous substance 168 is delivered from cartridge 166 to applicator 254, compensates for the pressure exerted by glutinous substance 168 on applicator 254 such that second portion 206 of compliant assembly 202 is allowed to move relative to first portion 204 of compliant assembly.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2, 3, 5, and 17, apparatus 102 further comprises pressure sensor 158, configured to generate an output based on the pressure of glutinous substance 168 in applicator 254. The regulated pressure within first cylinder 272 of each of at least one biasing mechanism 217 is adjusted based on, at least in part, the output of pressure sensor 158. The preceding subject matter of this paragraph characterizes example 50 of the present disclosure, wherein example 50 also includes the subject matter according to example 49, above.

Adjusting the regulated pressure within first cylinder 272 of each of at least one biasing mechanism 217 based on, at least in part, the output of pressure sensor 158 allows the force generated in first cylinder 272 to be adjusted to compensate for changes in the pressure of glutinous substance 168 in applicator 254.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-12, 14, and 17, compliant assembly 202 further comprises at least one guide 208, configured to movably couple first portion 204 and second portion 206 of compliant assembly 202 and to align second portion 206 and first portion 204 along central axis 121 of sleeve 106. The preceding subject matter of this paragraph characterizes example 51 of the present disclosure, wherein example 51 also includes the subject matter according to any one of examples 46-50, above.

At least one guide 208 of compliant assembly 202 allows movement of first portion 204 and second portion 206, while promoting alignment of first portion 204 and second portion 206 along central axis 121 of sleeve 106.

In some examples, at least one guide 208 comprises a rod, fixed relative to one of first portion 204 and second portion 206 and movably received within a complementary channel formed in another of first portion 204 and second portion 206.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 3-12 and 14-17, apparatus 102 further comprises sleeve interface 200, translationally fixed relative to sleeve 106. The preceding subject matter of this paragraph characterizes example 52 of the present disclosure, wherein example 52 also includes the subject matter according to any one of examples 46-51, above.

Sleeve interface 200, being translationally fixed relative to sleeve 106, facilitates coupling of compliant assembly 202 and automated coupler 223 with sleeve 106.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 8-12, 14, and 17, compliant assembly 202 is selectively movable relative to sleeve interface 200 along central axis 121 of sleeve 106. First portion 204 of compliant assembly 202 comprises second cylinder 213, movably retaining sleeve interface 200 and comprising first chamber 215 and second chamber 219. Sleeve interface 200 separates first chamber 215 from second chamber 219. The preceding subject matter of this paragraph characterizes example 53 of the present disclosure, wherein example 53 also includes the subject matter according to example 52, above.

Compliant assembly 202, being selectively movable relative to sleeve interface 200 along central axis 121 of sleeve 106 and fixed relative to sleeve 106, enables compliant assembly 292 to be selectively movable relative to sleeve 106 along central axis 121 of sleeve 106. Second cylinder 213 of compliant assembly 202 facilitates controllable translational movement of compliant assembly 202 relative to sleeve interface 200. Sleeve interface 200 separating first chamber 215 of second cylinder 213 from second chamber 117 of second cylinder enables a double-acting piston configuration.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-12, 14, and 17, compliant assembly 202 further comprises sixth pressure input 214, through which pressure is selectively introduced into first chamber 215 of second cylinder 213 to move first portion 204 of compliant assembly 202 relative to sleeve interface 200, enlarging first chamber 215 and contracting second chamber 219, until second portion 206 of compliant assembly 202 is in contact with sleeve interface 200. The preceding subject matter of this paragraph characterizes example 54 of the present disclosure, wherein example 54 also includes the subject matter according to example 53, above.

Contact between second portion 206 of compliant assembly 202 and sleeve interface 200 prevents movement of second portion 206 of compliant assembly 202, and thus applicator 254, toward sleeve 106 along central axis 121 of sleeve 106. In one example, preventing movement of second portion 206 of compliant assembly 202 toward sleeve 106 facilitates the automated coupling of applicator 254 with leading end 167 of cartridge 166 and decoupling of applicator 245 from leading end 167 of cartridge 166.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-12, 14, and 17, compliant assembly 202 further comprises seventh pressure input 216, through which pressure is selectively introduced into second chamber 219 of second cylinder 213 to move first portion 204 of compliant assembly 202 relative to sleeve interface 200, enlarging second chamber 219 and contracting first chamber 215 until second portion 206 of compliant assembly 202 is a predetermined distance away from sleeve interface 200. The preceding subject matter of this paragraph characterizes example 55 of the present disclosure, wherein example 55 also includes the subject matter according to any one of examples 53 or 54, above.

Moving first portion 204 of compliant assembly 202 a predetermined distance away from sleeve interface 200 enables movement of second portion 206 of compliant assembly 202 relative to first portion 204 of compliant assembly 202. The predetermined distance between second portion 206 of compliant assembly 202 and sleeve interface 200 is selected to facilitate a maximum desired range of motion or give between first portion 204 and second portion 206 of compliant assembly 202 before second portion 206 contacts sleeve interface 200 to prevent further motion of second portion 206 relative to first portion 204.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2, 3, 5-12, 14, and 17, compliant assembly 202 further comprises one or more proximity sensors 210, mounted to one of first portion 204 or second portion 206 of compliant assembly 202 and communicatively coupled with controller 157. One or more proximity sensors 210 are configured to determine at least one of the presence or the degree of the contact between applicator 254 and surface 172 of workpiece 170 and to communicate a command, descriptive of at least one of the presence or the degree of contact between applicator 254 and surface 172 of workpiece 170 to controller 157. The preceding subject matter of this paragraph characterizes example 56 of the present disclosure, wherein example 56 also includes the subject matter according to any one of examples 46-55, above.

Proximity sensor 210 promotes the detection of movement between first portion 204 of compliant assembly 202 and second portion 206 of compliant assembly 202.

Additionally, communicating commands, descriptive of the presence, degree, or both presence and degree of contact between applicator 254 and surface 172 of workpiece 170, to controller 157 enables controller 157 to direct robot 152 to avoid or reduce damage to surface of workpiece. For example, controller 157 can direct robot 152 to at least one of stop movement of apparatus 102 and applicator 254 relative to surface 172 of workpiece 170 or move apparatus 102 and applicator 254 away from surface 172 of workpiece 170 when the presence of contact is detected by proximity sensor 210 and/or the degree of contact detected by proximity sensor 210 meets a predetermined threshold.

In some examples, compliant assembly 202 includes a sensing device, fixedly coupled to one of first portion 204 and second portion 206 of compliant assembly 202, and a sensed target, such as a magnet, fixedly coupled to another of first portion 204 and second portion 206 of compliant assembly 202. According to one example, the sensed target is one of first portion 204 and second portion 206 itself. Generally, the sensing device of compliant assembly 202 is configured to sense a position of the sensed target relative to the sensing device using any of various position sensing techniques, such as emitting an electromagnetic signal from the sensing device and detecting changes in a signal returned from the sensed target.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2, 3, 5-12, 14, and 17, one or more proximity sensors 210 are configured to determine at least one of the presence or the degree of the contact between applicator 254 and surface 172 of workpiece 170 based on a distance detected between first portion 204 and second portion 206 of compliant assembly 202. The preceding subject matter of this paragraph characterizes example 57 of the present disclosure, wherein example 57 also includes the subject matter according to example 56, above.

Detecting a distance between first portion 204 and second portion 206 of compliant assembly 202 that is less than a contact-free distance between first portion 204 and second portion 206 of compliant assembly 202, associated with a pre-set maximum distance between first portion 204 and second portion 206 of compliant assembly 202, ensures applicator 254 has made contact with surface 172 of workpiece 170. Correspondingly, detecting a distance between first portion 204 and second portion 206 of compliant assembly 202 that equals a threshold distance, which is smaller than the contact-free distance, ensures applicator 254 has not only made contact with surface 172 of workpiece 170, but may also indicate relative movement between applicator 254 and first portion 204 of compliant assembly 202 is prevented or will soon be prevented.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2, 3, 5-12, 14, and 17, each of one or more proximity sensors 210 comprises a hall effect sensor.

A first one of two proximity sensors 210 is configured to determine the presence of the contact between applicator 254 and surface 172 of workpiece 170 and to communicate a command, descriptive of the presence of contact between applicator 254 and surface 172 of workpiece 170, to controller 157. A second one of two proximity sensors 210 is configured to determine the degree of the contact between applicator 254 and surface 172 of workpiece 170 and to communicate a command, descriptive of the degree of contact between applicator 254 and surface 172 of workpiece 170, to controller 157. The preceding subject matter of this paragraph characterizes example 60 of the present disclosure, wherein example 60 also includes the subject matter according to example 46, above.

Two proximity sensors 210 enables one proximity sensor 210 to be calibrated to detect the presence of contact between applicator 254 and surface 172 of workpiece 170 and another proximity sensor 210 to be calibrated to detect the degree of contact between applicator 254 and surface 172 of workpiece 170. Such a configuration promotes simplicity and reliability in determining the presence and the degree of contact between applicator 254 and surface 172 of workpiece 170.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2, 3, 5-12, 14, and 17, the first one of two proximity sensors 210 is configured to determine the presence of the contact between applicator 254 and surface 172 of workpiece 170 based on a first distance detected by the first one of two proximity sensors 210 between first portion 204 and second portion 206 of compliant assembly 202. The second one of two proximity sensors 210 is configured to determine the degree of the contact between applicator 254 and surface 172 of workpiece 170 based on a second distance detected by the second one of two proximity sensors 210 between first portion 204 and second portion 206 of compliant assembly 202. The preceding subject matter of this paragraph characterizes example 61 of the present disclosure, wherein example 61 also includes the subject matter according to example 60, above.

Determining the presence and degree of contact between applicator 254 and surface 172 of workpiece 170 based on distances between first portion 204 and second portion 206 of compliant assembly 202 allows for the use of proximity sensors, which, compared to other types of sensors, promote simple, accurate, and reliable measurement detection.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-17, system 100 for delivering glutinous substance (168) from cartridge (166) to surface (172) of workpiece (170) is disclosed. System 100 comprises applicator 254, configured to be reversibly sealingly coupled with leading end 167 of cartridge 166. System 100 further comprises robot 152, comprising tool interface 156. Additionally, system 100 comprises apparatus 102, comprising robot interface 136, configured to be coupled to tool interface 156 of robot 152.

The preceding subject matter of this paragraph characterizes example 70 of the present disclosure, wherein example 70 also includes the subject matter according to any one of examples 62-68, above.

Contact regulator 201, being configured to enable a limited degree of contact between applicator 254 and surface 172 of workpiece 170, promotes a reduction in potentially damaging impacts from applicator 254 to surface 172 of workpiece 170 as applicator 154 delivers glutinous substance 168 to surface 172 of workpiece 170. In other words, in some examples, contact regulator 201 is configured to limit damage to workpiece 170 or applicator 254 caused by inadvertent impacts between applicator 254 and surface 172 of workpiece 170. Coupling contact regulator 201 between sleeve 106 and automated coupler 223 allows apparatus 102 to both automatically reversibly sealingly couple applicator 254 with leading end 167 of cartridge 166 and enable a limited degree of contact between applicator 254 and surface 172 of workpiece 170.

Referring generally to FIGS. 1A and 1B and particularly to, e.g., FIGS. 2-12 and 14-17, contact regulator 201 causes the limited degree of contact between applicator 254 and surface 172 of workpiece 170 at least partially by communicating a command, descriptive of at least one of the presence or the degree of contact between applicator 245 and surface 172 of workpiece 170, to controller 157 to cause robot 152 to move applicator 254 responsive to the command. The preceding subject matter of this paragraph characterizes example 71 of the present disclosure, wherein example 71 also includes the subject matter according to example 70, above.

Adapter tube 226 facilitates communicative coupling between applicator 254, when applicator 254 is fixed to applicator mount 244 and application mount 244 is releasably interlocked with engagement assembly 224, and cartridge 166. For example, adapter tube 226 provides a fluid conduit through which glutinous substance 168 can flow from cartridge 166 to applicator 254. Sealing engagement between adapter tube 226 and leading end 167 of cartridge 166 facilitates containment of glutinous substance 168 as it flows from cartridge 166 to adapter tube 226.

Referring generally to, e.g., FIGS. 2-17 and particularly to FIGS. 18A and 18B, method 300 of delivering glutinous substance 168 from cartridge 166 to applicator 254 is disclosed. Method 300 comprises (block 302) receiving cartridge 166 inside sleeve 106 through inlet 124 of sleeve 106 when pressure cap 110, coupled to sleeve 106 proximate inlet 124, is in an open position.

Method 300 also comprises (block 304) moving pressure cap 110 into a closed position to sealingly couple pressure cap 110 with trailing end 169 of cartridge 166. Additionally, method 300 comprises (block 306) selectively causing automated coupler 223 to automatically sealingly couple applicator 254 with leading end 167 of cartridge 166 when cartridge 166 is inside sleeve 106 and pressure cap 110 is in the closed position. Method 300 further comprises (block 308) applying pressure to glutinous substance 168 in cartridge 166 through first pressure input 118 of pressure cap 110 to urge glutinous substance 168 from cartridge 166 into applicator 254. The preceding subject matter of this paragraph characterizes example 74 of the present disclosure.

Method 300 facilitates a reduction in the labor, time, and inaccuracies associated with the application of glutinous substances onto surfaces of workpieces. Cartridge 166 provides modular containment of glutinous substance 168. Sleeve 106 enables a secure coupling of cartridge 166 relative to valve 154. Movement of pressure cap 110 between the open position and closed position allows both access to sleeve 106 for the insertion of cartridge 166 into sleeve 106 and the application of pressure to cartridge 166 for urging glutinous substance 168 out of sleeve 106. With cartridge 166 received within sleeve 106 and pressure cap 110 in a closed position, cartridge 166 is sealed with applicator 254 to enable sealed flow of glutinous substance 168 from cartridge 166 to applicator 254 via the application of pressure to glutinous substance 168 in cartridge 166. Automated coupler 223 facilitates quick automated sealed coupling of applicator 254 with apparatus 102 and quick automated releasing or decoupling of applicator 254 from apparatus 102.

Referring generally to, e.g., FIGS. 2-5 and 15 and particularly to FIG. 18A, according to method 300, (block 316) pressure cap 110 is pivotally coupled to arm 115. Moving pressure cap 110 into the closed position comprises (block 318) rotating arm 115 in a first rotational direction about axis 117 that is fixed relative to sleeve 106 and that is perpendicular to central axis 121 of sleeve 106. Moving pressure cap 110 into the open position comprises (block 314) rotating arm 115 about axis 117 in a second rotational direction, opposite the first rotational direction. The preceding subject matter of this paragraph characterizes example 75 of the present disclosure, wherein example 75 also includes the subject matter according to example 74, above.

Referring generally to, e.g., FIGS. 2-5 and 15 and particularly to FIG. 18A, according to method 300, moving pressure cap 110 into the closed position comprises (block 320) torsionally biasing pressure cap 110 relative to arm 115. The preceding subject matter of this paragraph characterizes example 76 of the present disclosure, wherein example 76 also includes the subject matter according to example 75, above.

Because arm 115, to which pressure cap 110 is coupled, rotates to move pressure cap 110 into the closed positioned, in sealed engagement with trailing end 169 of cartridge 166, enabling pressure cap 110 to pivot relative to arm 115 allows pressure cap 110 to maintain coaxial alignment with trailing end 169 of cartridge 166 as arm 115 rotates. By pivotally or torsionally biasing pressure cap 110, biasing element 122 ensures pressure cap 110 is coaxially aligned with trailing end 169 of cartridge 166 as pressure cap 110 initially engages trailing end 169 of cartridge 166. In this manner, pressure cap 110 can properly engage and seat within trailing end 169 of cartridge 166 without binding with or crookedly entering trailing end 169 of cartridge 166.

The preceding subject matter of this paragraph characterizes example 77 of the present disclosure, wherein example 77 also includes the subject matter according to any one of examples 74 or 75, above.

Releasably locking pressure cap 110 in the closed position prevents disengagement between pressure cap 110 and cartridge 166 should actuator 114 fail. In other words, in the event actuator 114 fails to urge pressure cap 110 in closed position, such as due to loss of pressure to or malfunction of actuator 114, while pressure is applied to glutinous substance 168 in cartridge 166, releasably locking pressure cap 110 in the closed position prevents pressure within cartridge 116 from inadvertently moving pressure cap 110 out of the closed position.

Referring generally to, e.g., FIGS. 2-5 and 15 and particularly to FIGS. 18A and 18B, according to method 300, moving pressure cap 110 into the closed position comprises (block 312) pneumatically causing actuator 114, coupled to pressure cap 110, to have a first length. Releasably locking pressure cap 110 in the closed position comprises (block 330) mechanically locking pressure cap 110 in the closed position. The preceding subject matter of this paragraph characterizes example 78 of the present disclosure, wherein example 78 also includes the subject matter according to example 77, above.

Actuator 114 facilitates automated movement of pressure cap 110 into the closed position. Mechanically locking pressure cap 110 in the closed position provides a secure and reliable way to prevent disengagement between pressure cap 110 and cartridge 166 should actuator 114 fail.

Referring generally to, e.g., FIGS. 2-5 and 15 and particularly to FIG. 18B, according to method 300, (block 332) lock mechanism 112 is used to mechanically lock pressure cap 110 in the closed position. When lock mechanism 112 is in a locked position, lock mechanism 112 remains in locked position if actuator 114 loses pressure. The preceding subject matter of this paragraph characterizes example 79 of the present disclosure, wherein example 79 also includes the subject matter according to example 78, above.

Using lock mechanism 112 to mechanically lock pressure cap 110 in the closed position prevents disengagement between pressure cap 110 and cartridge 166 should actuator 114 fail. In other words, in the event actuator 114 fails to urge pressure cap 110 in closed position, such as due to loss of pressure to or malfunction of actuator 114, while pressure is applied to glutinous substance 168 in cartridge 166, lock mechanism 112 locks pressure cap 110 in the closed position to prevent pressure within cartridge 116 from inadvertently moving pressure cap 110 out of the closed position.

Referring generally to, e.g., FIGS. 2-5 and 15 and particularly to FIG. 18A, according to method 300, moving pressure cap 110 into the open position comprises (block 312) pneumatically causing actuator 114 to have a second length different from the first length. The preceding subject matter of this paragraph characterizes example 80 of the present disclosure, wherein example 80 also includes the subject matter according to any one of examples 78 or 79, above.

Actuator 114 facilitates automated movement of pressure cap 110 into the open position.

Referring generally to, e.g., FIGS. 2-5 and 15 and particularly to FIG. 18B, method 300 further comprises (block 334) disabling operation of actuator 114 while pressure is applied to glutinous substance 168 in cartridge 166 through first pressure input 118 of pressure cap 110. The preceding subject matter of this paragraph characterizes example 81 of the present disclosure, wherein example 81 also includes the subject matter according to example 80, above.

Disabling operation of actuator 114 while pressure is being applied to glutinous substance 168 in cartridge 166 through pressure input 118 of pressure cap 110 prevents actuator 114 from inadvertently opening pressure cap 110 while cartridge 166 is pressurized. Preventing pressure cap 110 from opening while pressure is being applied to glutinous substance 168 due to inadvertent actuation of actuator 114 ensures pressure within cartridge 166 is not inadvertently released.

Referring generally to, e.g., FIGS. 2-5 and 15 and particularly to FIG. 18B, according to method 300, applying pressure to glutinous substance 168 in cartridge 166 through first pressure input 118 of pressure cap 110 comprises (block 326) introducing a pressurized gas into cartridge 166 through first pressure input 118. The preceding subject matter of this paragraph characterizes example 82 of the present disclosure, wherein example 82 also includes the subject matter according to any one of examples 74-81, above.

Introducing a pressurized gas into cartridge 166 through pressure input 118 enables precise application of pneumatic pressure to glutinous substance 168 in cartridge 166 to precisely control the flow of glutinous substance 168 out of cartridge 166 and into applicator 254. Moreover, introducing a pressurized gas into cartridge 166 through pressure input 118 facilitates the use of automated pneumatic controls to control the pneumatic operation of pressure input 118 of pressure cap 110.

Referring generally to, e.g., FIGS. 2-5 and 15 and particularly to FIG. 18B, method 300 further comprises (block 336) sensing a temperature of glutinous substance 168 in applicator 254. Pressure applied to glutinous substance 168 in cartridge 166 through first pressure input 118 of pressure cap 110 varies responsive to, at least in part, the temperature of glutinous substance 168, sensed in applicator 254. The preceding subject matter of this paragraph characterizes example 83 of the present disclosure, wherein example 83 also includes the subject matter according to example 82, above.

Sensing the temperature of glutinous substance 168 enables detection of the pressure of glutinous substance 168 in valve 154.

Varying the pressure applied to glutinous substance 168 in cartridge 166 responsive to, at least in part, the sensed temperature of glutinous substance 168 facilitates a precise and predictable flow of glutinous substance 168 from applicator 254 to surface 172 of workpiece 170.

Referring generally to, e.g., FIGS. 2-5 and 15 and particularly to FIG. 18B, method 300 further comprises (block 338) sensing a pressure of glutinous substance 168 in applicator 254. The pressure applied to glutinous substance 168 in cartridge 166 through first pressure input 118 of pressure cap 110 varies responsive to, at least in part, the pressure of glutinous substance 168, sensed in applicator 254. The preceding subject matter of this paragraph characterizes example 84 of the present disclosure, wherein example 84 also includes the subject matter according to any one of examples 82 or 83, above.

Sensing the pressure of glutinous substance 168 enables detection of the pressure of glutinous substance 168 in valve 154. The sensed pressure of glutinous substance 168 in valve 154 can be used to control the rate at which glutinous substance 168 flows from cartridge 166 to valve 154. Varying the pressure applied to glutinous substance 168 in cartridge 166 responsive to, at least in part, the sensed pressure of glutinous substance 168 facilitates a precise and predictable flow of glutinous substance 168 from applicator 254 to surface 172 of workpiece 170.

Referring generally to, e.g., FIGS. 4, 8-12, 14, 16, 17 and 15 and particularly to FIG. 18A, according to method 300, selectively causing automated coupler 223 to automatically sealingly couple applicator 254 with leading end 167 of cartridge 166 comprises (block 324) pressurizing a first pneumatic circuit of engagement assembly 224 to move piston 230 relative to sleeve 106 in a first direction to cause engagement assembly 224 to interlock with applicator mount 244 that is coupled with applicator 254. The preceding subject matter of this paragraph characterizes example 85 of the present disclosure, wherein example 85 also includes the subject matter according to any one of examples 74-84, above.

Releasable interlock between engagement assembly 224 and applicator mount 244 promotes a secure, yet releasable, coupling of applicator mount 244 to engagement assembly 224. Moving piston 230 relative to sleeve 106 in the first direction promotes reliable releasable interlocking between engagement assembly 224 and applicator mount 244. Moreover, moving piston 230 by pressurizing the first pneumatic circuit of engagement assembly 224 facilitates precise control of the coupling of applicator mount 244 with engagement assembly 224.

The preceding subject matter of this paragraph characterizes example 86 of the present disclosure, wherein example 86 also includes the subject matter according to example 85, above.

Releasable interlock between engagement assembly 224 and applicator mount 244 promotes a secure, yet releasable, coupling of applicator mount 244 to engagement assembly 224. Moving piston 230 relative to sleeve 106 in the first direction promotes reliable releasable interlocking between engagement assembly 224 and applicator mount 244. Moreover, moving piston 230 by pressurizing the first pneumatic circuit of engagement assembly 224 facilitates precise control of the coupling of applicator mount 244 with engagement assembly 224.

According to one example, the second pneumatic circuit of engagement assembly 224 includes third pressure input 2240 and associated pressure tube(s), pressure source(s), and chamber of a cylinder within which piston 230 moves.

Referring generally to, e.g., FIGS. 2-12 and 14-17 and particularly to FIG. 18C, method 300 further comprises (block 342) limiting a degree of contact between applicator 254 and surface 172 of workpiece 170. The preceding subject matter of this paragraph characterizes example 87 of the present disclosure, wherein example 87 also includes the subject matter according to any one of examples 74-86, above.

Limiting the degree of contact between applicator 254 and surface 172 of workpiece 170 promotes a reduction in potentially damaging impacts from applicator 254 to surface 172 of workpiece 170 as applicator 154 delivers glutinous substance 168 to surface 172 of workpiece 170.

Referring generally to, e.g., FIGS. 2-12 and 14-17 and particularly to FIG. 18C, method 300 further comprises (block 348) determining at least one of a presence or the degree of contact between applicator 254 and surface 172 of workpiece 170. The preceding subject matter of this paragraph characterizes example 88 of the present disclosure, wherein example 88 also includes the subject matter according to example 87, above.

Determining at least one of the presence or the degree of contact between applicator 254 and surface 172 of workpiece 170 provides feedback for controlling movement of apparatus 102 to avoid or reduce damage to surface 172 of workpiece 170 due to inadvertent impacts between applicator 254 and surface 172 of workpiece 170. For example, when the presence or the degree of contact between applicator 254 and surface 272 of workpiece 170 is determined, apparatus 102 can be controlled to move applicator 254 away from surface 172 of workpiece 170 to limit the contact between applicator 254 and surface 172 of workpiece 170 and avoid damage to surface 172 of workpiece 170 or to applicator 254 or prevent further damage to surface 172 of workpiece 170 or to applicator 254.

Referring generally to, e.g., FIGS. 2-12 and 14-17 and particularly to FIG. 18C, according to method 300, limiting the degree of contact between applicator 254 and surface 172 of workpiece 170 comprises (block 344) communicating a command, descriptive of at least one of the presence or the degree of contact between applicator 245 and surface 172 of workpiece 170, to controller 157, configured to cause robot 152 to move applicator 254 relative to surface 172 of workpiece 170 responsive to, at least in part, the command. The preceding subject matter of this paragraph characterizes example 89 of the present disclosure, wherein example 89 also includes the subject matter according to example 88, above.

Controller 157, being configured to direct robot 152 to move apparatus 102 and applicator 254 relative to surface 172 of workpiece 170 based at least in part on a command, descriptive of at least one of the presence or the degree of contact between applicator 254 and surface 172 of workpiece 170, facilitates automatic adjustment of the position of the apparatus 102 and applicator 254 when the presence or the degree of contact between applicator 254 and surface 172 of workpiece 170 is determined. Robot 152 facilitates programmable, precise, and responsive control e.g., movement of apparatus 102 and applicator 254.

Referring generally to, e.g., FIGS. 2-12 and 14, and 17 and particularly to FIG. 18C, according to method 300, limiting the degree of contact between applicator 254 and surface 172 of workpiece 170 comprises, (block 346) when applicator 254 contacts surface 172 of workpiece 170 and a fixed location on sleeve 106 is within a predetermined spatial range away from surface 172 of workpiece 170, urging applicator 254, movable relative to sleeve 106, away from sleeve 106 with a biasing force, whose magnitude is inversely proportional to a distance between the fixed location on sleeve 106 and surface 172 of workpiece 170 and is less than a magnitude of a force sufficient to damage at least one of applicator 254 or workpiece 170 during a contact therebetween. The preceding subject matter of this paragraph characterizes example 90 of the present disclosure, wherein example 90 also includes the subject matter according to any one of examples 88 or 89, above.

Biased movement between applicator 254 and sleeve 106 enables applicator 254 to, at least partially, give way upon contacting surface 172 of workpiece 170 such that impact forces imparted to surface 172 by applicator 254 are reduced.

In one example, the degree of contact between applicator 254 and surface 172 of workpiece 170 is limited by both allowing biased movement of applicator 254 relative to sleeve 106, and moving applicator 254 away from surface 172 of workpiece 170 or stopping movement of applicator 254 relative to surface 172 of workpiece 170. In this manner, applicator 254 is allowed to contact surface 172 of workpiece 170 with a contact force incapable, or less capable of, damaging workpiece 170 or applicator 254, due to the biased movement of applicator 254 relative to sleeve 106, until the contact force reaches a threshold, associated with a contact force capable of causing, likely to cause, or soon will cause damage to workpiece 170 or applicator 254, at which time applicator 254 can be moved away to reduce or eliminate contact between applicator 254 and surface 172 of workpiece 170 or movement of applicator 254 can be stopped to ensure contact force does not increase.

Referring generally to, e.g., FIGS. 2-5 and 15 and particularly to FIG. 18A, method 300 further comprises (block 310) moving pressure cap 110 into an open position to provide clearance sufficient for removal of cartridge 166 from sleeve 106 through inlet 124 of sleeve 106. The preceding subject matter of this paragraph characterizes example 91 of the present disclosure, wherein example 91 also includes the subject matter according to any one of examples 74-90, above.

Moving pressure cap 110 into the open position enables removal of cartridge 166 from sleeve 106 and enables insertion of cartridge 166 into sleeve 106 without obstruction by pressure cap 110.
