DESCRIPTION OF PREFERRED EMBODIMENTS

[0085] It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features.

[0086] Referring to the drawings there is shown a lightweight linear gauge system 30 for accurately positioning a device such as a cutting tool relative to a workpiece supported on a support surface such as a conveyor 81 (best seen in FIG. 11) for precision work on the work piece.

[0087] As shown in FIGS. 6 and 7, the linear gauge system 30 broadly comprises a linear gauge 41 forming a rail made of precision lightweight material mounted to a weight bearing elongated support frame 51 made from heavier grade material such as steel.

[0088] The linear gauge 41 is mounted to the support frame 51 by a series of spaced apart bolts 45 passing through a central portion of the linear gauge and fastening to a floor portion of the support frame. In FIG. 6 the elongated support frame 51 is a strong hollow structure formed by at least two L-sections that interfit to form the hollow structure.

[0089] The linear gauge system further includes a carriage 61 movably mounted on the linear gauge 41 over bearings 65 on the linear gauge. The linear gauge 41 is formed precisely and separately to the elongated support frame 51, and mounted to the elongated support frame to provide the strength to the linear gauge.

[0090] In FIGS. 6 to 8, 13 and 15 the carriage 61 is generally an inverted U-shape over the linear gauge and within the elongated support, engaging the linear gauge by bearings therebetween. The ability to have a small precise linear gauge means that unlike the prior art the inverted U-shape is also relatively small as it merely fits over the linear gauge but is within the elongated support. This also means that instead of the linear gauge providing the strength and weight bearing features as in the prior art, the linear gauge of the present invention is smaller, less complex, higher precision, lighter hence portable, and less expensive to make from aluminium.

[0091] As seen in FIGS. 8 to 11, and 15, the linear gauge system 41 further includes a platform 62 mounted on the carriage 61, which is adapted to engage a workpiece on the weight bearing elongated frame. In the embodiment shown in FIGS. 8 and 15, a portion of the platform extends away from the weight bearing frame and is able to support a device mounted on the carriage.

[0092] In particular as shown in FIGS. 8 and 15, the weight bearing elongated support frame 51 includes a slot 91 extending along the elongate support frame 51 receiving an edge portion 63 of the platform 62 therethrough, wherein as the carriage 61 moves along the linear gauge 41, the platform moves relative to the slot 91 to position the edge portion.

[0093] The edge portion 63 of the platform protrudes through the slot 91 to provide a support platform for receiving a workpiece thereon, and moves along the slot with the carriage for precise positioning of the workpiece relative to a processing tool (not shown).

[0094] As shown in FIGS. 9 to 12, 15 and 17, the linear gauge system 30 further includes a drive means 75. In FIGS. 9 to 11 and 15 the drive means 75 is provided in the form of a belt drive system comprising a belt loop drive 76 and a drive motor 85. Several alternative arrangements are shown in FIGS. 9 to 11 where the belt loop 76 of the belt drive is either offset from the linear gauge 41, overlaps with the linear gauge 41, or is configured in parallel with the linear gauge 41. As shown in FIGS. 10 and 12 the gauge system 30 can be mounted to a conveyor structure 81 having a series of spaced rollers on a conveyor platform and height adjustable legs 105. In this embodiment the platform 62 also includes a mounting plate 82 to which a processing device such as a cutting tool or a workpiece can be attached.

[0095] As best shown in FIGS. 16 and 17, the belt loop drive 76 includes a pair of opposite buckles 21a and 21b adapted to be fixed to opposite sides of the platform 62 by aligned openings in a mounting part of the buckles and the platform 62 and fastening by means of through bolts 22.

[0096] As seen in FIG. 17, the buckles 21a and 21b are fitted with end portions of a belt 76, and the belt thus forms a loop structure (see FIG. 13) which is driven in a looped pathway by a drive motor 85 through which the belt engages and passes. In one embodiment shown in FIGS. 12 and 14 the motor is located externally on one end of and offset from the elongate support frame.

[0097] The linear gauge 41 is fabricated from a lightweight material such as aluminium thus reducing the weight of the linear gauge system 1 and labor costs for manufacture.

[0098] The linear gauge system 30 further includes a control system 91 which controls movement and positioning of the platform 62 along the support frame according to precise measurement of the linear gauge 41. In one embodiment a device can be mounted on the movable platform and the control means accurately locates the device at precise measurements along the elongated frame according to the precision measurements of the linear gauge.

[0099] The control means comprises an operating system which controls the positioning of the movable platform 62 along the linear gauge 41 according to predetermined measurement requirements and location information according to the linear gauge.

[0100] The drive means in one embodiment shown in FIG. 12 is functionally operated by a control operating system 91. This system includes a gradation system comprising a series of spaced apart openings on the linear gauge 41 extending along the length of the linear gauge at predetermined spacings, light emitting devices for dispersing light through the spaced openings, light sensing devices for detecting light through the openings, and a communication system for receiving and relaying information from the light sensing devices to a motor control.

[0101] As shown in FIGS. 10 to 11b as the movable platform traverses the linear gauge, at least a part of the platform covers one or more adjacent openings for a given location. Light detection changes are sensed by light detectors located on or close to the linear gauge and information transferred to an operating central control unit 31. The central control unit programmed for determining location of the platform relative to the linear gauge.

[0102] Turning to FIGS. 12 and 13 the linear gauge 41 of the linear gauge system 30 includes a longitudinal shaped linear gauge 41 mounted to and extending along a floor portion of the elongate support 51 by spaced apart fastening bolts 45.

[0103] The platform 62 of the linear gauge system 30 is received by and movable over the weight bearing frame 51 by drive means 75 located offset to and above the linear gauge 41. In the figures the drive means includes a motor 85 mounted to and externally of the elongate support frame 51 and being interconnected to the continuous drive belt 76 forming a looped circuit. As shown the continuous belt 76 is connected to a part of the platform 62 by mounting buckles. The belt extends in a continuous loop around spigots 72, 74 at or near spaced ends of the weight bearing frame and connected to opposing sides of the platform by the mounting buckles to enable selective positioning of the platform by moving the carriage along the linear gauge with the weight bearing being provided by the elongate support frame 51.

[0104] As shown the movable 62 is mounted to a linear gauge carriage 61, wherein the linear gauge carriage 61 has an internal longitudinal inverted U-shaped recess 27 with a complimentary cross-section to the linear gauge 41. As shown in the figures, the linear gauge carriage 61 is adapted to move over the linear gauge, and in so doing displace the platform along the elongate support frame extending through slotted opening 91 with bearings 65 aiding the sliding movement of the carriage 61 relative to the linear gauge.

[0105] In a further embodiment shown in FIG. 4, the platform includes an upright support plate 82 that extends away from the weight bearing frame 51. In combination the upright support plate and platform provide support for a device such as a cutting tool on the linear gauge carriage 61.

[0106] The linear gauge 41 in one embodiment substantially overlies the linear gauge 41. In an alternative embodiment the weight bearing elongated frame substantially encloses the linear gauge.

[0107] The linear gauge system includes a drive means including a continuous belt fixed to the platform, and a motor for driving the platform 62 and carriage via the continuous belt. A control means 91 controls the movement of the platform 62 by the drive means along the elongate frame over the linear gauge 41 according to precise measurement determined according to the control system.

[0108] Referring to FIG. 24, there is shown a process and method for precise positioning and cutting using a linear gauge system according to the present invention. The process includes providing a small lightweight aluminium gauge 121 having precision measurements along an elongated path. The lightweight gauge is mounted along a floor portion of a heavier self-supporting elongate support jacket or frame 122. The support jacket 122 can be formed from a single or multi-component structure and the gauge is attached to the support to provide structural integrity for the lightweight gauge. The support jacket also includes a longitudinal slotted opening to receive and allow free movement of a platform. A movable carriage 132 having a complementary receiving structure is mounted to the gauge to allow movement of the carriage along the gauge. A support platform 141 is mounted to the carriage and at least a portion of the platform extends through the slotted opening in the elongate support jacket. The system includes a drive means, a gradation system, and a control means 151 in communication with the gradation system operable to control the drive means.

[0109] The drive means includes a continuous belt affixed to the platform, and a motor adapted to drive the belt and therefore move the carriage along the gauge to alter the position of the platform along the elongate support.

[0110] The gradation system includes a series of spaced apart openings on the linear gauge 41 extending along the length of the linear gauge at predetermined spacings, light emitting devices for dispersing light through the spaced openings, light sensing devices for detecting light through the openings, and a communication system for receiving and relaying information from the light sensing devices to the control means. The control means receives input data for locating a work piece or a processing tool on the platform at a predetermined location along the elongate support jacket for performing a task on the work piece. The control means operates to control the motor, and receives feedback from the gradation system which allows the control means to control the motor to locate the carriage and platform according to precise measurement determined according to the control means.

[0111] This form of the present invention can provide the following benefits:

a. The linear gauge is precision engineered from lightweight material.
b. The linear gauge is substantially non-weight bearing hence can be made from material such as aluminium,
c. Greater precision on linear gauge for locating a device for performing work in a work piece

[0144] Linear Gauge System| Special Applications

[0145] Linear gauge system length Stop and Feeder come optionally with automatic yield maximisation nesting. It is available as a stock management software solution for your office, or as a console-integrated solution for the floor. Linear gauge system yield nesting optimisation process is designed to be intuitive and simple to use, whether you manage it from the office or from the console.

[0146] From-the-office stock management software seamlessly integrates with Linear gauge system such that you can wirelessly drag-and-drop or e-mail optimised cut lists to the linear gauge system, where it is automatically loaded ready for the operator.

[0147] The improved system is designed so that yield nesting does not require cumbersome stock management. Simply measure the material length and enter it into the linear gauge system. It then optimizes the job list, all you have to do is cut. Measure next one, and repeat. You can also just select continuous stock if your material lengths are all the same after which there is no measuring. With the Linear gauge system feeder, the material length is automatically measured by an optical sensor during feeding. So all your operator has to do is put the material on the table and press GO.

[0148] With Linear gauge system you can setup a drilling part file with an unlimited number of holes and hole position data. You can setup your job using either absolute position for each hole, or relative to the last hole, or a mix. With a push of a button, Linear gauge system moves the work piece to first hole position, with the hole information displayed for the operator (diameter, depth, etc.). Your operator simply drills with information provided, and goes on drilling using hole data, line by line. When all holes are drilled, Linear gauge system will alert the operator part has been completed. Accurately drilled, no mistakes, every time.

[0149] Have you got production requiring complex maths equations based on length?

[0150] Say for example you're producing fencing cross-bars where you must measure the bar length and then calculate how many holes you can place on the bar, often in a special pattern. Linear gauge system feeder automatically measures the lengths of the tubes placed on it and then can optionally be programmed to execute any mathematical equations you require for any hole pattern needed for production. This will be initiated during feeding and holes will be pressed according to the calculated pattern at high-speed, without delays. Accurately pressed, no mistakes, every time.

[0151] Have you got a cut-to-length business with many small-quantity jobs?

[0152] Set up your business operations with the Linear gauge system linked directly to your front counter. Cut data (profile types, lengths and quantity) can be sent wirelessly and automatically from the front counter to Linear gauge system at the execution of each sale. At the saw, operator reads the information for the job just sold on the Linear gauge system screen, fetches the correct stock, presses GO, and cuts the order. On job completion, operator presses Job Complete and Linear gauge system alerts Goods Despatch (or the Customer) that the order is ready to go, in a fully integrated business operations system.

[0153] Linear gauge system Attachments

[0154] We have a range of standard and special-application attachments for any stop gauge or feeding requirement. Standard attachments not suitable? We can make any solution you need, and chances are that whatever you need, we've made before. If you want to make your own attachment, you can, many of our Customers do. Linear gauge system machines have a standardised three-bolt mount designed for easy attachment changeover.
