Example embodiments relate to a tile or masonry saw assembly, and more particularly relate to a tile or masonry saw assembly that is configured to improve the capability of the saw to cut larger materials.
When a user is laying bricks or other masonry workpieces, sometimes the workpieces need to be cut. Cutting may be accomplished with diamond or other cutting blades on either tile or masonry saws. The saws may be provided as a saw assembly that may include a table for supporting a workpiece to be cut and structures for manipulating the position of the saw. Such saw assemblies may need to be transported between job sites and thus, there may be certain size limitations that must be considered to keep the saw assemblies portable. However, by limiting the size of the saw assembly, the size of the table and therefore also the size of the workpiece that can be cut may be limited.
Therefore there is a need for a saw assembly that can provide sufficient capability to support larger workpieces and enable such workpieces to be effectively cut in consideration of space constraints. As such, some example embodiments may provide a saw assembly that includes a movement assembly configured to enable double movement of the saw and a workpiece support. Some example embodiments may provide for the movement of the workpiece support and the saw to move in opposite directions, and at a selected ratio (e.g., 2:1) to effectively increase the relative movement obtainable between the saw and the workpiece support so that larger workpieces can be cut on a small area.
In accordance with an example embodiment, a tile or masonry saw assembly may therefore be provided. The tile or masonry saw assembly may include a saw, a frame, and a workpiece support. The saw may include a motor operable to turn a blade assembly to cut a workpiece. The frame may be operably coupled to the saw to enable the saw to be moved along the frame in a first direction. The workpiece support may be operably coupled to the frame to support the workpiece relative to the saw, and to allow the workpiece support to be moved along the frame. The saw assembly further includes a movement assembly via which both movement of the workpiece support and movement of the saw relative to the frame is accomplished, such that a movement of the work piece support along the frame in a second direction is enabled to cause the saw to move along the frame in the first direction which is opposite the second direction.
In the following description of preferred embodiments, reference will be made to the accompanying drawings, in which,
The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which example embodiments of the invention incorporating one or more aspects of the present invention are shown. In the drawings, like numbers refer to like elements.
As mentioned above, some example embodiments may provide operators with the ability to increase the amount of relative motion that is achievable between a saw and a workpiece support so that larger workpieces can be cut in a smaller area. Some example embodiments may be employed in the context of wet cutting that is designed to reduce the amount of dust generated during a cutting operation. However, the water handling aspects of some components are not necessary to be implemented in all example embodiments. Thus, some example embodiments may be employed for dry cutting operations as well.
As shown at least in
The frame 120 may include a water collection system 121 that operates to collect at least some of the water that is applied to the blade assembly 114. The water collection system 121 may include a collector 122 disposed at one end of the frame 120. The collector 122 may extend between lateral sides of the frame 120 from one longitudinal end of the frame 120 toward a water tank 124 that is disposed at the opposite longitudinal end of the frame 120. Thus, the collector 122 and the water tank 124 may combine to form a surface for collecting any water expelled from the blade assembly 114 during operation.
The collector 122 may generally lie horizontally within the frame 120 and may include sloped sides that direct water from areas near the lateral edges of the collector 122 toward a longitudinal centerline of the frame 120. The collector 122 may also be sloped to direct water away from the longitudinal end of the frame 120 to which the collector 122 is proximate toward the water tank 124.
The water tank 124 may collect the water provided thereto by the collector 122 for reuse in application of water to the blade assembly 114. Thus, the water collection system 121 of an example embodiment may provide a relatively efficient way to apply, collect and reuse water for wet cutting. As mentioned above, the water collection system 121 and the components thereof may be omitted in some embodiments.
The frame 120 may also include a workpiece support 126, which may provide a framework for supporting workpieces that are to be cut using the saw 110. The workpiece support 126 may be a substantially planar support structure that extends transversely across the frame 120 to hold workpieces being cut. The workpiece support 126 may be enabled to slide or roll along the longitudinal length of the frame 120 such that it is supported above either or both of the collector 122 and the water tank 124. The workpiece support 126 may include trenches 128 or cutout portions that define recesses in which the cutting element of the blade assembly 114 may rotate when a cutting operation is conducted. The trenches 128 may also operate to direct any water that is sprayed therein or otherwise collects therein to either or both of the collector 122 and the water tank 124.
As shown in
In an example embodiment, the blade assembly 114 may include a blade guard 150 that may be used to both apply and capture water used for wet cutting. The captured water may be delivered to the water collection system 121 for storage and/or reuse. In this regard, for example, a blade of the saw 110 may be at least partially housed within the blade guard 150. However, the blade guard 150 may leave less than half of the blade exposed and therefore shield only the remaining, unexposed portion.
Although an example embodiment has been described above in the context of a masonry saw (i.e., masonry saw 100), it should be appreciated that example embodiments may also be practiced in other contexts. Accordingly,
In an example embodiment, the rollers may be within a track system or otherwise some form of enclosure inside which the rollers may be maintained. The track system may keep the rollers from moving up/down, but allow the rollers to move freely along the length of the frame 120. The track system of the movement assembly 300 may be provided with an aperture 302 that is defined at one end and along each opposing side of the frame 120 of the saw assembly 100. The workpiece support 126 may be removed by sequentially removing the rollers that ride on the rails from the track system via the aperture 302. By enabling the workpiece support 126 to be removed, the saw assembly 100 may be cleaned and serviced more completely and easily.
Referring now primarily to
The double movement with a 2:1 ratio described above may be accomplished via the structures of
In an example embodiment, a first rail 310 and a second rail 320 may extend along the side of the frame 120, the sides preferably made of extruded aluminium. The first rail 310 may have a higher elevation than the second rail 320 within the frame 120 in some cases. In an example embodiment, the first rail 310 may be one of a pair of rails 310, 310′ that extend along opposite sides of the frame 120 to support rollers of a first roller assembly 312, 312′ that movably supports the workpiece support 126. Similarly, the second rail 320 may also be one of a pair of rails 320, 320′ that extend along opposite sides of the frame 120 to support a second roller assembly 322, 322′ that may be operably coupled to the support arm 130 of the saw 110.
The rollers of the second roller assembly 322 may be operably coupled to a first movable pulley 330 and a second movable pulley 332 that are operably coupled to cable 340 which is also coupled to the first and second fixed pulleys 305 and 307. Meanwhile, the workpiece support 126 may also be releasably coupled to the cable 340 via a clamp 350. As indicated above, some of the structures of the movement assembly 300 may be mirrored on the opposite side of the frame 120 as well. This mirroring is shown in
As can be appreciated from
In some cases, movement of the support arm 130 along the second rail 320 may cause corresponding movement of the first and second movable pulleys 330 and 332 over a predefined distance along the second rail 320. Meanwhile, movement of the workpiece support 126 along the first rail 310 may be enabled over a second predefined distance that may be about twice the first predefined distance based on the 2:1 ratio.
In some cases, the first and second fixed pulleys 305 and 307 may be disposed to lie in a plane substantially parallel to the plane in which the workpiece support 126 lies. However, the first and second movable pulleys 330 and 332 may lie in a plane that is substantially perpendicular to the plane in which the first and second fixed pulleys 305 and 307 lie. In an example embodiment, the rollers of the first roller assembly 312, and the rollers of the second roller assembly may each lie in respective different planes that are each substantially parallel to the plane in which the first and second movable pulleys 330 and 332 lie.
Based on the descriptions and drawings provided above, it should be appreciated that a tile or masonry saw assembly of an example embodiment may include a saw, a frame and a workpiece support. The saw may include a motor operable to turn a blade assembly to cut a workpiece. The frame may be operably coupled to the saw to enable the saw to be moved along the frame in a first direction. The workpiece support may be operably coupled to the frame to support the workpiece relative to the saw, and to allow the workpiece support to be moved along the frame. The saw assembly further includes a movement assembly via which both movement of the workpiece support and movement of the saw relative to the frame is accomplished, such that a movement of the work piece support along the frame in a second direction is enabled to cause the saw to move along the frame in the first direction which is opposite the second direction.
The saw assembly of some embodiments may include additional features that may be optionally added either alone or in combination with each other. For example, in some embodiments, (1) the movement assembly may be configurable to provide a 2:1 ratio for movement of the workpiece support compared to movement of the saw. In an example embodiment, (2), the movement assembly may include a first pair of rails to which the workpiece support is operably coupled via a first roller assembly, and a second pair of rails to which a support arm of the saw is operably coupled via a second roller assembly. In some example embodiments, (3) a first movable pulley and a second movable pulley, respectively, may be coupled to the support arm. The first and second movable pulleys may be operably coupled to a flexible coupling member. In some cases, (4) the first movable pulley and the second movable pulley may be coaxial with respective ones of rollers of the second roller assembly. In an example embodiment, (5) the workpiece support may be removably attached to the flexible coupling member. In some embodiments, (6) the workpiece support may be operably coupled to the flexible coupling member via a clamp that provides removable attachment between the workpiece support and the flexible coupling member.
In some embodiments, any or all of (1) to (6) may be employed in addition to the optional modifications or augmentations described below. For example, in some embodiments, movement of the support arm along the second rail causes corresponding movement of the first and second movable pulleys over a first predefined distance along the second rail. In such an example, movement of the workpiece support along the first rail may be enabled over a second predefined distance that is about twice the first predefined distance. Additionally or alternatively, the movement assembly may include a first fixed pulley fixed to a portion of the frame proximate to a first end of the first rail and a second fixed pulley fixed to a portion of the frame proximate to a second end of the first rail. The first and second fixed pulleys may be operably coupled to the flexible coupling member. Additionally or alternatively, the movement assembly may include a first end member to which the flexible coupling member is fixed at a portion of the frame proximate to a first end of the first rail and a second end member to which the flexible coupling member is fixed at a portion of the frame proximate to a second end of the first rail. Additionally or alternatively, at least one of the first end member or the second end member may be adjustably fixed to the frame, so that slack of the flexible coupling member is removable by tightening. Additionally or alternatively, the first and second fixed pulleys may lie in a plane substantially perpendicular to a plane in which the first and second movable pulleys lie. Additionally or alternatively, the support arm and the workpiece support may be movable independently of each other, or in correspondence with each other via the movement assembly. Additionally or alternatively, the first rail and the second rail may extend substantially parallel to each other and substantially parallel to a longitudinal centerline of the frame. Additionally or alternatively, an aperture may be arranged on both sides of the frame on at least one end of the saw, such that rollers of a corresponding end of the workpiece support are enabled to be lifted up through the aperture, and thereafter the rollers of the other end of the workpiece support are enabled to be lifted up through the same aperture. This feature could also be used for a saw having the support arm fixed to the frame, so that only the workpiece support could be moved along the frame. Additionally or alternatively, for a saw having a movement assembly the clamp may be enabled to be loosened relative to the flexible coupling member to enable the workpiece support to be lifted from the frame.
