Mechanical firing adapter for a M81 device

Abstract

A mechanical firing adapter for an igniter, such as an M81, to enable remotely firing the igniter using a robot, such as a MTRS. MTRS are used in the disposal/disruption of IEDs. Igniters are generally used with a shock tube, a type of fuse that is used with explosive charges, like shape charges. The adapter has a base plate with a first area to secure the igniter, a second area to withdraw the igniter's pull-rod by the attached pull-ring, and a compound assembly that interfaces with a robot. The pull-ring is attached to a sled that moves rearward when a clinching force is applied to opposing paddles, which causes the connected angled articulating struts to spread open. The paddles are moved closer by a remote controlled robotic jaw, and this closing movement causes the sled to move rearward, pulling out the pull-rod, which sets off the explosive.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates generally to explosive tools and more particularly to a means of remotely initiating an M81 shock tube igniter.

2. Background

An M81 igniter is used to ignite a time blasting fuse or to initiate a shock tube. Shock tube is a thin plastic tube with a thin layer of special explosive material deposited on its interior surface. The standard M81 igniter has the following visible components: a small plastic tube with a pull-ring on a pull-rod projecting from one end, a safety (cotter) pin that passes through the tube, and a screw cap that secures a holding mechanism for the fuse or shock tube. The igniter can accommodate a shock tube or a time blasting fuse. A two-piece plastic plug allows proper securing of the shock tube (with just inner piece removed) or the time blasting fuse (with both pieces removed). A partially cut away prior art view of an M81 is shown in FIG. 6.

The M81 was engineered to be manually actuated by the operator. The ignition sequence is typically as follows: An operator (explosive expert) while positioning an explosive charge at the desired distance from the target, begins dispenses shock tube/time blasting fuse from the dispenser. After the explosive charge has been positioned, the operator moves away, continuing to dispense the shock tube/time blasting fuse until a sufficient pay-out length has been deployed to reach a safe area for personnel. The shock tube is then connected to the igniter. To make this connection the operator loosens the screw cap and removes some or all of the inner piece of the two-piece plastic plug, cuts off an end of the tube/fuse and inserts it in the hole from which the plug was removed. The screw cap is then re-tightened to secure the fuse or shock tube. The safety (cotter) pin can then be removed. To initiate the M81, while holding the body of the M81, the operator uses his other hand to pull on the pull-ring, which in turn pulls out the pull-rod. The pull-rod pulls the firing-pin against the force of a spring. When the limit of travel is reached, the pull-rod releases the firing-pin, which is forced by the spring into the primer, which fires with a flame and an explosive shock which ignites the fuse or initiates the shock tube, therein detonating the explosive charge.

In more recent developments, the shock tube can be manually initiated using an electrical spark produced by a sparking device attached to a robotic device. In both cases (M81 and sparking device) manual ignition is required. An example of the robotic device is the MTRS platform (Man Transportable Robotic System). Initiating shock tube by hand requires the robot operator to maneuver the robot from the target site, dispense a sufficient pay-out length until enough has been deployed for the operator to move away, while continuing the dispensing shock tube, to a safe area. This method of operation is time consuming and prevents additional investigation once the shock tube deployment begins. Another method of initiating shock tube is by an electrical spark produced by a firing device attached to the MTRS robotic platform. This method requires tethering the robot to the shock tube. The tethering prevents free movement of the robot, and is problematic. For instance, if a robot runs over the shock tube, the shock tube can become tangled in the drive tracks of the robot, limiting the robot's movement.

SUMMARY OF THE INVENTION

The disclosed invention, in one aspect, is a mechanical firing adapter for an igniter, such as M81 and M60, where the firing adapter enables the igniter to be actuated by an MTRS (Man Transportable Robotic Systems), where the MTRS is generally remotely controlled.

An igniter with the disclosed mechanical firing adapter enables a robotic arm to effect movement that simulates manual activation of legacy igniters. The robot can and usually is remotely controlled. Taken together, the invention therein is also a method to activate, remotely, an igniter fitted with the invented adapter. In another aspect, the invention uses a Man Transportable Robotic System (MTRS) platforms, which are relatively less expensive systems. The mechanical firing adapter enables the remote controlled robot to not only deploy an explosive charge to an incident site, where the incident site is where the charge is detonated, but the igniter and shock tube can also be deployed by using the MTRS. The operator is positioned at a safe distance, and the robot can maneuver freely until the explosive has been set up and conditions are ready to fire the explosive charge. The robot's distance to a safe location is significantly closer to the incident site than what is consider acceptably safe for personnel.

The mechanical firing adapter, in another aspect, includes a base plate with a first area with a frame for fastening the igniter to a front-side of the base plate; a second area for withdrawing the pull-rod axially from the igniter, where upon being withdrawn to a limit of travel, the igniter is activated. The second area generally includes a plurality of elongate slots, where each elongate slot has a length that is at least as long as the limit of travel. A compound assembly completes the interface between the robot and the igniter. Robots typically have an arm with a clamping jaw with a closing action for picking up items. When the jaw is closed the compound assembly converts the closing action into a substantially linear movement that is orthogonal to the closing action. The linear movement causes a controlled withdrawal of the pull-rod from the igniter.

The compound assembly includes a sled element that can linearly move across the base plate tracking along a medial line. The sled element has a medial hitch onto which the pull-ring can be attached, and the elongate slots serve as a tracking mechanism for the sled element to connect to the base plate. The compound assembly includes a pair of opposing paddles conformed to be simultaneously held and brought towards each other when the robotic jaw closes. Each of the pair of opposing paddles is attached to at least two articulating struts, at least one to the front and at least one to the rear, such that the front and rear struts are angled with respect to each, and when the angle between struts is small the distance between opposing paddles is much larger than when the angle is larger. As will be shown, a relatively small decrease in the distance between opposing paddles produces a significant opening of the angle and spreading of the front and rear struts.

The movement of the struts is possible, because each strut is pivotal on both ends, and at least one front articulating strut is pivotally attached to a front pivotal pin on the paddle, and the strut extends forward to a front pin on the first area of the base plate. At least one rear articulating strut is pivotally attached to a rear pin on the paddle and the rear strut extends rearward to a sled pin.

When a clinching force is applied by the robotic jaw, such as by a pair of opposing surfaces on hydraulic pistons or motorized geared jaws, the pair of opposing paddles move toward each other causing the articulating elements to spread, therein forcing the sled element, which as previously described is connected to the rear struts with rear pivotal pins, to move toward the rear. The pull-ring is jointly attached to the sled's medial hitch and the pull-rod, movement of the sled to the rear withdraws the pull-rod, quickly reaching the limit of travel. Accordingly, the pull-rod releases the firing pin, which is forced by the spring into the primer. The primer fires with a flame and an explosive shock, that will ignite an attached fuse or an attached shock tube.

In another aspect, the invention is a method to activate, remotely, an igniter mounted on the invented adapter. The method may include using the MTRS to place an explosive charge and dispense the shock tube from a dispenser; setting down the dispenser down; and using the MTRS to perform other functions; paying out additional shock tube if required; and using the MTRS to robotically initiate the shock tube.

Among other advantages, the mechanical firing adapter for an M81 device provides a means of mechanically initiating an M81 shock tube igniter remotely with the Man Transportable Robotic System (MTRS) platforms. This configuration allows an operator to deploy a robot to an incident site, and both the operator and robot may maneuver freely until it is time to fire the explosive charge. The robot may be moved to a safe location, where the robot may use the adapter to initiate, mechanically, the shock tube initiation system.

DETAILED DESCRIPTION OF THE INVENTION

The mechanical firing adapter provides the compatibility of using a robotic arm to utilize legacy igniters, such as a M81, where generally the igniter is in communication with an explosive charge via a shock tube that is connected on one end to the igniter and on a distal end of the shock tube is connected to the explosive charge. The legacy igniter is defined herein to mean that it was originally engineered for manual activation. The compatibility eliminates the need for manual activation of the igniter, and this feature enables the use of a shorter length of shock tube with less exposure of personnel to a potentially dangerous target area/incident site. The invented mechanical firing adapter provides a mechanism for using remotely controlled robots to conduct, effectively, a nominally manual operation robotically. The net effect is the continued use of the igniter, like the M81, thus extending the useful life of a stock piled standard item, preventing its obsolescence, and providing Man Transportable Robotic System (MTRS) platforms with a new tool for other possible applications. The invention is also a method to activate, remotely, an igniter fitted with the invented adapter, and in so doing reduce the chance of a robot's tracks and other components to be snarled by the shock tube.

As shown in FIG. 6, the legacy igniter 81 has a body 83 with a primer end 85 with a firing-pin 87, a primer 89, a spring 91, and an opposing end 93 having a pull-rod 95 with an attached safety cotter pin 97, a pull-ring 99 and a limit of travel 101 as shown in FIG. 2.

Referring to FIG. 1, the firing adapter 10 includes: a base plate 20 having a front edge 22, a front-side 24, a back-side 26 (See FIG. 4), a perimeter edge 28, and a rear edge 30. The legacy igniter 81 is not an element of the invention, and as such it is shown with dashed lines. The illustrated base plate 20 is substantially rectangular, but other shapes are anticipated. For instance, a round base plate would provide improved lateral stability. The base plate could also have legs, and more than one layer.

The mechanical firing adapter 10 has a first area 12. Included in the first area 12 is a frame 14, functionally dimensioned to secure the igniter 81 on the front-side 24 of the base plate 20. The front side 24 of the base plate 20 has eyelets 32 through which a cable strap 34 is cinched around the igniter's body 83, further securing the igniter 81 in the frame 14. A second area 16 of the plate 20 is used to withdraw the pull-rod 95 axially from the igniter's body 83, where upon being retracted a distance that is the limit of travel 101 (as shown in FIG. 2), the igniter 81 is activated. The second area 16 includes a plurality of elongate slots 40, which are apertures extending through the base plate, where each elongate slot has a length that is at least as long as the distance of the limit of travel. The illustrated slots include a medial first slot 42, where the medial first slot extends lengthwise, aligned coplanar with the pull-rod. Additionally, there is a lateral second slot 44 and a lateral third slot 46. The lateral slots 44,46 are substantially parallel to the medial slot 42. The medial slot substantially bisects the lateral slots 44,46. Cumulatively, the elongate slots serve as a tracking mechanism for the sled element to connect to the base plate.

The firing adapter 10 has a compound assembly 58 that when clinched converts a closing action into a linear movement that is a substantially orthogonal to the closing action. The linear movement produces a controlled withdrawal of the pull-rod from the igniter. The compound assembly includes a sled element 50 that may be linearly moved across the base plate 20, tracking along the medial first slot 42. The sled element 50 has a medial hitch 52 onto which the pull-ring can be attached. There are a pair of opposing paddles 60 conformed to be held and clinched by a single robotic jaw (not show), where a first paddle 60₁ is attached to at least two articulating first struts 70₁,70₂. Each first strut is pivotal on both ends, and at least one front articulating first strut 70₁ is pivotally attached to a first front pin 80₁ of the first paddle 60₁ and extends to the first area of the base plate where it is pivotally attached to a first block pin 14₁. The first block pin 14₁ projects substantially perpendicular from the base plate and is located proximate to a primer end 85 (see FIG. 6) of the frame 14. At least one rear articulating first strut 70₂ is pivotally attached to a rear pin 80₂ of the first paddle 60₁ and extends to the second area of the base plate where it is pivotally attached to a first sled pin 50₁. The first sled pin 50₁ projects substantially perpendicular from the sled 50 and is located approximately lateral to the medial hitch 52 and substantially over the lateral second slot 44. A second paddle 60₂, that is substantially a mirror of the first paddle 60₁, is attached to at least two articulating second struts 72. Each second strut 72 is pivotal on both ends, where at least one front articulating second strut 72₁ is pivotally attached to a front pin 82₁ of the second paddle 60₂ and extends to the first area 12 of the base plate where it is pivotally attached to an opposing first block pin 14₂. The opposing first block pin 14₂ projects substantially perpendicular from the base plate 20 and it is located proximate to the other side of the primer end 85 of the frame 14. There is at least one rear articulating second strut 72₂ pivotally attached to a rear pin 82₂ of the second paddle 60₂. The strut 72₂ extends to the second area 16 of the base plate 20, where it is pivotally attached to a second sled pin 50₂. The second sled pin 50₂ projects substantially perpendicular from the sled 50 and it is located on the opposing side of the sled element, approximately lateral to the medial hitch 52 and substantially over the lateral third slot 46.

When a clinching force is applied by the jaw on the robotic arm, the pair of opposing paddles, 60₁ and 60₂, move toward each other causing the articulating elements 70 to spread, therein forcing the sled element to move away from the first area of the base plate toward the rear edge 30.

The pull-ring, which is jointly attached to the sled's medial hitch and the pull-rod, withdraws the pull-rod, quickly reaching the limit of travel 101 (as shown in FIG. 2). On reaching the limit of travel, the pull-rod releases the firing pin 87 (see FIG. 6), which is forced by the spring 91 into the primer 89, which fires with a flame and an explosive shock that will ignite an attached fuse or an attached shock tube.

Referring to FIG. 2, which is an elevational perspective view of the exemplary embodiment shown in FIG. 1, wherein the paddles have been partially moved together, causing the rearward movement of the sled. In FIG. 1, each of the paddles are initially about 0.875 inches (P_I), as measured from an inner bottom edge of a paddle to a lateral edge of the base plate. In FIG. 2 each of the paddles are closer, about ˜0.5 inches (P_F) as measured from an inner bottom edge of a paddle to a lateral edge of the base plate. The net movement of each paddle is about ˜0.375 inches closer to the lateral edge. In FIG. 1, the sled element, as measured from a rear edge of the sled element to a rear edge 30 of the base plate was initially about 1.685 inches (S_I); and in FIG. 2 the distance to the rear edge is about 0.875 inches (S_F). The net change for each paddle is the absolute value |P_F-P_I| or (0.875-0.50), which is about 0.375 inches. The net change for the sled element is the absolute value |S_F-S_I| or (1.685-0.875), which is about ˜0.81 inches. So, the sled element moves about twice as far as a paddle. This configuration is shown in FIG. 3. The limit of travel 101 is, of course, sign sensitive, as the pull-rod has to be withdrawn a finite distance, or else the firing pin will not be released, hence the use of the absolute brackets. As is evident from FIG. 2, there is still at least another 0.875 inches left in reserve. If more travel is desired, the invented adapter may be scaled up, and the struts may be made even longer. The adapter is dimensioned according to the requirements of the task.

Referring to FIG. 4, which is an elevation perspective view of another exemplary embodiment of the invented mechanical firing adapter 10′ for an igniter. In the current illustrated embodiment, there are a plurality of paired articulating elements, which imparts much improved torsional resistance, and overall improved ruggedness. The compound assembly 58 has a sled 50 with a traveler 51. The mechanical firing adapter is fitted with an igniter 81 having a body 83. In the illustrated embodiment, the cotter safety pin 97 is still in place. The base plate has a front-side 24, a back-side 26, and a perimeter edge 28. As before, the base plate has substantially two functional areas. There is a first area that includes framing elements 14_L, 14_R, 17_L and 17_R, where framing elements 14_L, 14_R secure the primer end of the igniter (the primer end connects to the shock tube), and the opposing framing elements 17_L, 17_R, which secure the opposing end of the igniter. In the illustrated embodiment, the eyelet 32 has a cinched cable tie 34 securing the body 83 of the igniter to the front-side 24 of the base plate 20. Additionally, there are blocks 15_L,15_R which are lateral to the framing elements 14_L,4_R, which in effect elevate and support the front bearing pins for some of the articulating struts.

There is a second area for withdrawing the pull-rod 95 axially from the igniter. As previously discussed, upon being withdrawn a distance that is a limit of travel, the igniter is activated. The second area includes a plurality of elongate slots 40, which are apertures extending through the base plate. Each elongate slot has a length that is at least as long as the distance of the limit of travel. The illustrated elongate slots include a medial first slot 42 that extends lengthwise. It is substantially aligned coplanar with the pull-rod 95. Also shown are a lateral second slot 44 and a lateral third slot 46, where the lateral slots 44,46 are substantially parallel to the medial slot 42. The medial slot 42 essentially bisects the lateral slots 44, 46.

The mechanical firing adapter has a compound assembly 58 that when force is applied as shown in the direction indicated by the large black arrows labeled F, the force produces a closing action. This closing action is converted into a substantially orthogonal linear movement. The linear movement produces a controlled withdrawal of the pull-rod from the igniter's body.

The sled element 50, pushed by the articulating struts, moves linearly across the base plate, tracking along the medial first slot 42. The sled element 50 has a medial hitch 52 onto which the pull-ring can be attached. The assembly has a pair of opposing paddles 60, where each paddle 60₁,60₂ is substantially lateral to the frame. Each paddle 60₁,60₂ has a vertical base 63₁,63₂ that enables a robotic arm with a hand or jaw to grasp and close the opposing paddles 60. FIG. 5a and FIG. 5b illustrate a portion of a robotic arm with a clamping jaw. The pivoting articulating struts 70₁,71₁ and 70₂,71₂, on the first paddle 60₁ has an outer front pin 81₁, an inner front pin 80₁, an outer rear pin 81₂ and an inner rear pin 80₂. The inner pins 80₁ and 80₂ are barely visible, obscured by the vertical base 63₁. The pairs of articulating first struts are substantially parallel. Each strut is pivotal on both ends. The pairs of articulating first struts include an outer front first strut 71₁, an inner front first strut 70₁, an outer rear first strut 71₂, and an inner rear first strut 70₂. The outer front first strut 71₁ extends from paddle pin 81₁ to the front of the base plate 20 where it is pivotally attached to a right block pin 15₁ protruding from a lateral right block 15_R. The right block pin 15₁ projects substantially perpendicular from the base plate 20, and it located proximate to the front end of the frame. The inner front first strut 70₁ extends from paddle pin 80₁ to the front of the base plate where it is pivotally attached to a first bearing pin 14₁. The first bearing pin 14₁ projects substantially perpendicular from the base plate and is located proximate to the right framing element 14_R. The outer rear first strut 71₂ extends rearward from paddle pin 81₂ to the second area of the base plate and is pivotally attached to a first traveler pin 51₁. The traveler 51 is seated on the sled element 50, and the first traveler pin 51₁ projects substantially perpendicular from the traveler 51. Its position is substantially lateral to the medial hitch 52, and substantially lateral to the lateral second slot 44. The inner rear first strut 70₂ extends from paddle pin 80₂ to the second area of the base plate and is pivotally attached to a first sleeved bearing pin 50₁ that is seated in a first lateral aperture 53_R. The first lateral aperture 53_R is substantially aligned with the lateral second slot 44.

The second paddle 60₂ has an outer front second pin 83₁, an inner front second pin 82₁, an outer rear second pin 83₂ and an inner rear second pin 82₂ to which are attached two pairs of parallel articulating second struts, where each strut is pivotal on both ends. The pairs of articulating second struts includes an outer front second strut 73₁, an inner front second strut 72₁, an outer rear second strut 73₂, and an inner rear second strut 72₂. The outer front second strut 73₁ extends from paddle pin 83₁ to a left block pin 15₁ protruding from a lateral left block 15_L. The left block pin 15₁ projects substantially perpendicular from the base plate 20, and it located proximate to the front end of the frame. The inner front second strut 72₁ extends from paddle pin 82₁ to the front of the base plate where it is pivotally attached to a second bearing pin 14₂. The second bearing pin 14₂ projects substantially perpendicular from the base plate and is located proximate to framing element 14_L. The outer rear second strut 73₂ extends from paddle pin 83₂ to a second traveler pin 51₂. The second traveler pin 51₂ is located substantially lateral to a rear of the medial hitch 52 and substantially lateral to the lateral third slot 46. The inner rear second strut 72₂ extends from paddle pin 82₂ to the second area of the base plate, and it is pivotally attached to a second sleeved bearing pin 50₂ seated in a second lateral aperture 53_L. The second lateral aperture 53_L is substantially aligned with the lateral third slot 46.

Referring to FIG. 5a, this figure is a substantially planar view of an actuatable clamping jaw 100. The clamping jaw 100 has a right plate element 102 seated on a first actuatable piston 106, where the first actuatable piston 106 is mounted on one side 110 of the clamping jaw 100. An opposing left plate element 104 is seated on a second actuatable piston 108 mounted on an opposing side 112 of the clamping jaw 100, where both the first actuatable piston 106 and the second actuatable piston 108 are retracted.

Referring to FIG. 5b, the pistons 106, 108 have been actuated, and are fully extended, narrowing a gap 120 between the right plate element 102 and the opposing left plate element 104.

The invention further includes a method of igniting an explosive charge. The method may include the steps of providing an explosive charge, a length of shock tube spooled on a dispenser, an igniter (such as M81) having a body with a primer end for attaching the shock tube and an opposing end having a pull-rod with an attached pull-ring, and a safety cotter pin, and a mechanical firing adapter to which can be fastened the igniter. The mechanical firing adapter has a base plate with a first area for securing the igniter, a second area including a sled element with a hitch to which the pull-ring can be fastened, and a compound assembly of opposing paddles connected to articulating struts. The struts convert a jaw-like closing motion of the paddles by a robotic arm into a translational linear movement of the sled element therein withdrawing the pull-rod. The method further includes attaching the shock tube to the igniter; and confirming the paddles are in the fully open position. The sled element is proximate to the first area. The method further includes attaching the igniter to the mechanical firing adapter; confirming by an inspection by a robot that an explosive charge may be moved close enough to the target to be effective, where during the inspection, the shock tube may be dispensed; setting up the explosive charge and connecting the shock tube to the explosive charge. The method further includes dispensing additional shock tube as needed; positioning the mechanical firing adapter such that the paddles are accessible and confirming that there is no clinching force on the paddles; confirming that a safety area is still clear; removing the safety pin; providing an additional safe region for any personnel; and closing the paddles utilizing a remote controlled robotic jaw, therein detonating the explosive charge.

Finally, any numerical parameters set forth in the specification and attached claims are approximations (for example, by using the term “about”) that may vary depending upon the desired properties sought to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of significant digits and by applying ordinary rounding.
