It should be understood that the structures, proportions, sizes, etc. shown in the drawings attached hereto are for the purpose of understanding and reading only and are not intended to limit the scope of the invention, which is defined by the appended claims, but rather by the appended claims. Also, the terms such as "upper", "lower", "front", "rear", "left", "right" and "a" and the like are used in this specification for convenience of description only and are not intended to limit the scope of the present invention, but the relative changes or modifications thereof are not to be construed as limitations of the present invention without substantial modification to the technical content.

Fig. 1A and 1A-1 are perspective views of a pore-forming device 5 of the present invention applied to a processing apparatus 1. As shown in fig. 1A and 1A-1, the processing apparatus 1 includes: a transporting device 1a, a height milling device 2, a side milling device 3, a turning device 4 and the hole forming device 5.

In the present embodiment, the processing apparatus 1 defines the direction of the production line as the left and right directions (e.g., arrow direction Y), the direction perpendicular to the production line as the front and rear directions (e.g., arrow direction X), and the height direction along the processing apparatus 1 as the up and down directions (e.g., arrow direction Z). It should be understood that this orientation is for illustration of the configuration of the present embodiment, and is not particularly limited.

The transporting device 1a is used for transporting (e.g. clamping) the target object 9 to a processing position of a desired production line, so that the transporting device 1a is configured at the upper periphery of the height milling device 2, the edge milling device 3, the turning device 4, the hole forming device 5, etc. for placing the target object 9, so as to facilitate placing the target object 9 on the height milling device 2, the edge milling device 3, the turning device 4 and/or the hole forming device 5.

In this embodiment, as shown in fig. 1B, the transporting device 1a includes at least one pick-and-place assembly 10 and a support assembly 11 movably supporting the pick-and-place assembly 10, so that the pick-and-place assembly 10 is used for picking and placing the target 9, and the pick-and-place assembly 10 is moved in cooperation with the support assembly 11 to move the target 9. For example, the supporting component 11 is a frame structure, which has two sets of door-shaped bar frames 110 arranged on two opposite sides of a foundation surface (such as a floor) and a cross beam 111 spanning between the bar frames 110, and the cross beam 111 is located above the height milling device 2, the edge milling device 3 and the turning device 4 to serve as a path for the displacement of the pick-and-place component 10. It should be appreciated that the variety of the support assembly 11 is not particularly limited.

Furthermore, the pick-and-place assembly 10 includes a pick-up portion 10a having the clamping member 100 and a carrying portion 10b for mounting the pick-up portion 10a. For example, the clamping member 100 of the clamping portion 10a can adjust the width D according to the requirement to clamp objects 9 with different widths, an oil hydraulic cylinder or a pneumatic cylinder (which is used as the power source 10D) can be used to control the distance between the two clamping portions 10a to clamp or release the objects 9, and the carrying portion 10B is a moving frame, which is erected on the beam 111 (such as the limiting member 112 arranged on the beam 111) in a manner of being perpendicular to the beam 111, and is pivoted with a gear (not shown), the gear (not shown) is meshed with a rack 112a (as shown in fig. 1B-1), and the gear uses a driving force to make a linear motion on the rack 112a, so that the picking and placing assembly 10 can make a linear motion on a sliding seat (such as the carrying portion 10B) and a sliding rail assembly (such as the limiting member 112a and the gear thereon) toward the arrow direction Y. Specifically, the clamping portion 10a drives the clamping members 100 to extend or retract (toward the arrow direction Y) by a plurality of power sources 10d (such as pneumatic or hydraulic cylinders shown in fig. 1B) to generate an opening or clamping action, and a telescopic structure 101 connected to the clamping portion 10a is disposed at the bottom of the carrying portion 10B to lift the clamping portion 10a. Preferably, a motor (not shown) for driving the carrier 10b to move is disposed above the carrier 10b to drive the gear to move linearly on the rack 112 a.

In addition, the number of the pick-and-place assemblies 10 can be set according to requirements. For example, the pick-and-place assembly 10 is disposed at the processing positions corresponding to the height milling device 2, the edge milling device 3 and the turning device 4, so at least two sets of pick-and-place assemblies 10 are disposed. Specifically, each of the pick-and-place assemblies 10 is respectively disposed between the height milling device 2 and the edge milling device 3, and between the height milling device 2 and the turning device 4, and the pick-and-place assemblies 10 can be additionally disposed between the rod frame 110 and the edge milling device 3 according to requirements, so that the plurality of pick-and-place assemblies 10 serve as intermediate transfer assemblies of the target object 9, and the target object 9 is continuously picked and placed to each processing position, so as to complete the processing flow of the whole production line.

For example, the object 9 is substantially rectangular (e.g. square plate), the bottom of the object 9 (e.g. the side of the second surface 9b is the bottom of the raised floor) is honeycomb-shaped, and the feet 90 are formed at four corners of the second surface 9b of the object 9, so that the four feet 90 are provided with openings 900 (as shown in fig. 1D), and the four feet 90 are respectively fixed to the supporting foot stand for the raised floor by screws. Specifically, the end surface 9d of the foot stand 90 slightly protrudes (as shown in the height difference h of fig. 1C-2) from the second surface 9b of the target 9, and a flange 91 protruding from the side surface 9C is formed at the edge of the first surface 9a, and the flange 91 is four edges of the raised floor to be processed by the edge milling device 3. The target object 9 of the present embodiment is a raised floor, and therefore, the target object 9 will be hereinafter referred to as a raised floor.

The milling device 2 is arranged at the middle stage of the processing flow of the whole production line, and cooperates with the conveying device 1a to process the end faces 9d of the footrests 90, for example, to remove burrs on the end faces 9d of the four footrests 90 of the raised floor so as to process the height dimension required by the processing of the raised floor.

For example, the first positioning member 22 is a frame (parallel frame as shown in fig. 2B), and the milling assemblies 2a are disposed on opposite sides (front and rear sides) of the first positioning member 22, and at least one fixing portion 220 (such as a corner cylinder fixture) may be disposed on the outer sides of the opposite sides of the first positioning member 22 as required. When in use, the corner cylinder clamps can be used as the fixing parts 220 which are correspondingly arranged on two opposite sides of the first positioning piece 22 to press the target 9 on the first positioning piece 22, so that the raised floor is fixed on the first base 21, and at least one corner cylinder clamp is respectively arranged on one side of the plurality of first positioning pieces 22, so that the displacement of the raised floor is limited and the deviation of the first positioning pieces 22 is avoided in the process of milling operation; further, at least one stop portion 220a may be disposed on the outer side of the first positioning member 22 and the other side perpendicular to the side of the first positioning member 22 on which the corner cylinder clamp is disposed, where the stop portion 220a blocks the side surface 9c of the raised floor, so as to facilitate the operator to place the target 9 on the first positioning member 22 (e.g. in the arrow direction Y1). It should be understood that the pick-and-place assembly 10 may also be configured to pick the object 9 to be processed from the feeding portion (which is located beside the left-hand bar 110, not shown) and place it in the processing position on the first positioning member 22.

Furthermore, each milling assembly 2a includes at least one first milling cutter tool 20 (two first milling cutter tools 20 are taken as an example in this embodiment), a first servo motor 26 for actuating the first milling cutter tool 20, at least one first supporting structure 23 movably disposed on the first base 21, a plurality of supporting frames 24 symmetrically disposed on the left and right sides of the first supporting structure 23 and for mounting the first milling cutter tools 20, and at least one adjusting member 25, wherein the embodiment is provided with two independent first supporting structures 23 and four independent supporting frames 24, and one independent first supporting structure 23 and two independent supporting frames 24 are used as a set (two sets of sets), such that the two sets are respectively disposed in parallel on opposite sides of the first positioning member 22, and two independent supporting frames 24 in a single set are respectively fixed on opposite sides of one independent first supporting structure 23, so that the plurality of first tools 20 on the supporting frames 24 can be simultaneously driven by the same power set 28 to the required height of the milling cutter seat 9 at a high speed. For example, the carrier 24 is an L-shaped carrier body, on the end side facing the target 9, the first servomotor 26 (as shown in fig. 2A or 2B) and the first milling tool 20 are arranged, so that the first milling tool 20 is operated by the first servomotor 26. Specifically, the first servomotor 26 operates the first milling tool 20 to rotate to machine the foot 90 of the target 9 to a desired height.

For example, the carrier 24 can be displaced by a guiding structure 24a, the guiding structure 24a comprises a sliding rail 240a and a sliding seat 241a engaging the sliding rail 240a, wherein the sliding rail 240a is respectively fixed on the surfaces of two opposite sides of the first supporting structure 23, the sliding seat 241a is fixed on the other end side of the carrier 24, such that when the rotating rod 250 rotates the rotating disc 251, the first milling tool 20 on the carrier 24 can be respectively driven to linearly move in the up-down direction (like arrow direction Z) on the sliding rail 240a, and the first milling tool 20 can be adjusted to the required height for processing the stand 90 according to the scale on the numerical instrument on the adjusting member 25. Specifically, a numerical instrument (not shown) may be disposed on the turntable 251 of the adjusting member 25 to clearly control the height position of the carrier 24, so that the first milling tool 20 can mill the four seats 90 of the target 9 to a desired height, such as from 56 mm of the height of the raised floor before milling to 55 mm after milling.

In addition, a driving member 27 for driving the first supporting structure 23 to move and a power unit 28 for driving the driving member 27 to move linearly are disposed on the first base 21 as required to drive the height milling assembly 2a to perform the height milling process on the target 9.

The edge milling device 3 is disposed at the forefront stage of the processing flow of the whole production line, and cooperates with the transporting device 1a to process the flange 91 of the target 9, for example, to remove burrs on the peripheral side edges of the raised floor, so as to process four edge sizes of the raised floor. Specifically, the machining values are input by a man-machine control interface in a programmable logic controller (Programmable Logic Controller, abbreviated as PLC) mode so as to control the sizes of four edges of the raised floor to be machined.

In this embodiment, as shown in fig. 3A, 3B and 3C, the edge milling device 3 includes at least one edge milling component 3A, a second base 31 configured to configure the edge milling component 3A, and a second positioning member 32 disposed at the center of the second base 31 for placing the target 9, so that the pick-and-place component 10 places the target 9 on the second positioning member 32, and the edge milling component 3A is displaced relative to the second positioning member 32 to perform edge milling processing on the target 9.

Specifically, the supporting frames 39 are respectively disposed on the front and rear sides of the second base 31, so that the fixing portions 320 are mounted on the supporting frames 39, and after the object 9 is placed on the placement platform, the plurality of fixing portions 320 are used to diagonally clamp and clamp the stand 90 of the object 9, so as to prevent the object 9 from deviating during edge milling, and the fixing portion 320a can also be disposed above the placement platform, so that when the plurality of fixing portions 320a are pressed down or pulled up by a power to perform a stretching action, the plurality of fixing portions 320a can press or separate the second surface 9b of the object 9.

Furthermore, each edge milling assembly 3a comprises a second milling cutter tool 30, a second supporting structure 33 arranged on the second base 31, a frame 34 arranged on the second supporting structure 33 for mounting the second milling cutter tool 30, and a second servo motor 36 arranged on the frame 34 for operating the second milling cutter tool 30, wherein the frame 34 is movably arranged on the second supporting structure 33, so that the frame 34 and the second milling cutter tool 30 are close to or far from the target 9 to displace the second milling cutter tool 30 to a required position, and the second milling cutter tool 30 is subjected to edge milling treatment of the target 9. For example, a combination of a guide rail and a slide is used, and a rail 35 is disposed on the upper side of the second support structure 33, so that the slide 340 under the stand 34 cooperates with the rail 35 to linearly and short-distance displace the second milling tool 30 to a desired processing position. Specifically, the stand 34 is provided with the second milling cutter tool 30 and a second servo motor 36 for rotating the second milling cutter tool 30, so that the second milling cutter tool 30 removes burrs of the flange 91 of the target 9 at a target position (e.g., the flange 91 abutting against the side 9c of the target 9).

The second support structure 33 is a plate base and is disposed on the second base 31 in a displaceable manner. For example, the second base 31 is further provided with a limiting member 37 for limiting the displacement direction of the second support structure 33 and a power unit 38 for driving the second support structure 33 and the stand 34 to displace, as shown in fig. 3B.

In addition, the power set 38 further includes a second motor 38b, and a rail 35 is fixed on the second supporting structure 33, at least one slider 340 matching with the rail 35 is fixed on the bottom of the frame 34, so that the slider 340 moves on the rail 35, and the second motor 38b drives the frame 34 to linearly displace relative to the second supporting structure 33, so that the second milling tool 30 can linearly displace to a desired planar position to approach or separate from the second positioning member 32. For example, based on one side of the second positioning member 32, the displacement direction (the moving direction f2, B2 shown in fig. 3B) of the second supporting structure 33 and the displacement direction (the moving direction f1, B1 shown in fig. 3B) of the stand 34 are perpendicular to each other. Specifically, a ball screw cap (not shown) and a ball screw (not shown) engaging the ball screw cap are secured to the underside of the frame 34 such that the second motor 38b rotates the ball screw, and the ball screw actuates the ball screw cap to produce a linear displacement, as the ball screw is merely rotated in situ, such that the ball screw cap linearly drives the frame 34 along the track 35 to linearly displace the second milling tool 30 to a desired machining position.

The turning device 4 is disposed between the height milling device 2 and the hole forming device 5 and cooperates with the transporting device 1a to turn over the first surface 9a or the second surface 9b of the target 9, for example, turn over the raised floor after deburring the end surface 9d of the footstand 90 to make the first surface 9a face upwards.

In this embodiment, as shown in fig. 4A or fig. 4B, the turning device 4 includes a third base 41, a shaft structure 40 disposed on the third base 41, a third positioning member 42 disposed on the third base 41, a third supporting structure 43 disposed on the third base 41 in a displaceable manner, and a driving member 47 disposed on the third base 41, wherein one end side of the third positioning member 42 is pivoted to the shaft structure 40 to turn over relative to the third base 41, and the driving member 47 drives the third positioning member 42 to force the third positioning member 42 to turn over and be located above the third supporting structure 43, so that the third positioning member 42 turns the target 9 onto the third supporting structure 43 after the pick-and-place assembly 10 places the target 9 on the third positioning member 42.

Furthermore, at least one fixing structure 42a may be disposed on the front and rear sides of the third positioning member 42 as required to limit the displacement of the target 9 from deviating from the third positioning member 42, and an abutting structure 44 may be disposed on the third base 41 as required to abut against the other end side of the third positioning member 42. Specifically, the fixing structure 42a is pushed and pulled by an oil cylinder (not shown), so that the fixing structure 42a engages with or separates from the third positioning member 42, and the fixing structure 42a abuts against or separates from the target 9.

In addition, the third supporting structure 43 is a feeding plate, and a set of guide rails 45 are disposed on the third base 41 corresponding to the third supporting structure 43, so that the third supporting structure 43 can move along the guide rails 45 between the third positioning member 42 and the hole forming device 5. For example, a plurality of displacement portions 430 (e.g., sliding blocks) are disposed on the bottom side of the third support structure 43, so that the third support structure 43 can move linearly along the guide rail 45 by means of the plurality of displacement portions 430 engaging with the guide rail 45, and the third support structure 43 is close to or far from the third positioning member 42. Specifically, the third supporting structure 43 is pulled by an oil cylinder (not shown), so that the third supporting structure 43 moves linearly along the guide rail 45.

In addition, the third positioning element 42 is a flipping board, and the driving element 47 (as shown in fig. 4A) is disposed on the third base 41 at the front side or the rear side to drive the third positioning element 42 to perform a flipping operation. For example, the driving member 47 includes a gear 471 and a rack 470 (as shown in fig. 4B), the rack 470 is engaged with the gear 471, and the gear 471 is pivotally connected to the shaft 401 of the shaft structure 40, so that when the rack 470 moves linearly, the gear 471 is driven to rotate, and the gear 471 rotates the shaft 401 to turn over the third positioning member 42 and locate above the third supporting structure 43. Specifically, the push-pull rod 480 of a power unit 48 (e.g. pneumatic or hydraulic cylinder) drives the rack 470 to move forward and backward in a straight line to rotate the gear 471. Preferably, at least one limit switch 49 is disposed on the third base 41 to control the telescopic distance of the push-pull rod 480, so that the rack 470 drives the rotation amplitude of the gear 471 to stably turn over the third positioning component 42.

The hole forming device 5 of the present invention cooperates with the turning device 4 to form at least one hole 900 (e.g., a countersunk hole as shown in fig. 1D) on the first surface 9a of the target 9, for example, a hole is drilled at the foot 90 of the raised floor to form a positioning hole of the raised floor.

In this embodiment, the turning device 4 and the hole forming device 5 are disposed at the same processing position, so that the turning device 4 and the hole forming device 5 cooperate with the same group of transportation devices 1 a.

As shown in fig. 4A and 5A, the hole forming device 5 includes a fourth base 51 adjacent to the third base 41, at least one fourth positioning member 52 disposed on the fourth base 51, a fourth supporting structure 53 disposed on the fourth base 51, at least one hole forming member 50 disposed on the fourth supporting structure 53 for forming a hole on the target 9, at least one power unit 55 for rotating the hole forming member 50, and at least one third servo motor 56 for lifting the hole forming member 50, and the third supporting structure 43 is moved relative to the third base 41 by providing an oil pressure or air pressure component (e.g. another power unit 48 a) to transfer the target 9 to the fourth base 51, so that the hole forming member 50 forms a hole 900 on the target 9.

In this embodiment, the fourth base 51 and the third base 41 may be disposed coplanar, and the fourth base 51 defines a processing area A1 and a discharging area A2, so that the fourth positioning member 52 is disposed at the edge of the processing area A1 to limit the target 9 in the processing area A1, and the fourth supporting structure 53 is covered over the processing area A1, so that the hole forming member 50 is disposed over the processing area A1 in a displaceable manner to perform hole forming on the foot seat 90 of the target 9, so as to achieve the drilling operation of the countersunk hole required at the foot seat 90 of the target 9, and the guide rail 45 extends into the processing area A1 of the fourth base 51. For example, after the third supporting structure 43 conveys the raised floor to the processing area A1 along the guide rail 45, the fourth positioning member 52 limits the target 9, so as to facilitate positioning of the target 9 on the fourth base 51.

Furthermore, the fourth positioning member 52 is disposed corresponding to the edge of the fourth base 51 to limit the displacement of the target 9, so that the target 9 does not deflect in the processing area A1. Specifically, according to the direction of the feeding (the third base 41 to the processing area A1) or the guide rail 45, the fourth positioning member 52 is disposed at the end point of the feeding path, such as the rear side and the right side of the processing area A1, so as to achieve the purpose of limiting the displacement of the feeding plate. For example, the fourth positioning member 52 is provided with a buffer member 520 (such as a wheel, a bearing or the like) at the top end thereof for sliding forward to contact the target 9, so that the feeding plate and the target 9 thereon are not strongly clamped when entering the processing area A1, thereby reducing friction.

In addition, the fourth supporting structure 53 is a frame body, which covers the machining area A1 corresponding to the machining area A1, on which at least one power unit 55 and a third servo motor 56 (as shown in fig. 5A) can be configured as required, and the hole forming member 50 is in the form of a step drill (as shown in fig. 5B) disposed at a corner of the fourth supporting structure 53 to drill holes at the footstand 90 of the raised floor to form countersinks.

In addition, a fixing structure 54a may be disposed corresponding to the fourth positioning member 52 to contact the object 9. For example, the fixing structure 54a, such as a physical pressure head or a vacuum suction head, is disposed below the fourth supporting structure 53, and the fixing structure 54a may be driven to press the target 9 by providing an oil pressure or a pneumatic assembly (not shown). Preferably, a front end, such as a rake-shaped actuating member 57, is disposed at the processing area A1 corresponding to the direction of the discharging area A2, and is of a telescopic structure, and an oil pressure or air pressure assembly (not shown) is used to push the side 9c of the target 9 in the processing area A1, so that the target 9 is forced to move to the discharging area A2 after the processing area A1 completes processing.

In another embodiment, as shown in fig. 5C, the third servo motor 56 can lift the hole forming member 50 by the lifting structure 58. For example, the power unit 55 is a spindle head driving motor, and as shown in fig. 5D, the lifting structure 58 includes a plurality of rails 58a disposed on the stand of the fourth supporting structure 53 and a lifting plate 58b movably disposed in cooperation with the rails 58a, such that a slidable slider 580 is disposed on the rails 58a, and the lifting plate 58b is provided with a sliding seat 581 corresponding to the slider 580, so that the lifting plate 58b can be lifted along the rails 58 a. Further, the third servo motor 56 may be fixed on top of the fourth supporting structure 53 by a speed reducer 560 to act a ball screw 561 and a nut seat 562, wherein the speed reducer 560 is connected to the ball screw 561, and the nut seat 562 is connected to the ball screw 561 and fixed on the lifting plate 58b, so that when the third servo motor 56 drives the speed reducer 560 to rotate the ball screw 561, the ball screw 561 can drive the lifting plate 58b at the bottom of the nut seat 562 to reciprocate linearly for a certain distance when rotating.

Preferably, the power set 55 and the hole forming member 50 can be respectively disposed on the upper and lower sides of the lifting plate 58b, a fixing plate 59a connected to the lower end of the power set 55 is fixedly disposed on the upper side of the lifting plate 58b, and a joint plate 59b connected to the upper end of the hole forming member 50 is fixedly disposed on the lower side of the lifting plate 58b, so that when the power set 55 drives the hole forming member 50 to rotate, the hole forming member 50 can be driven to do lifting rectilinear motion perpendicular to the surface of the processing area A1 by the cooperation of the lifting structure 58, so as to drill holes on the foot stand 90 of the raised floor.

It should be understood that the hole forming member 50 and the related arrangement around the hole forming member 50 can be designed according to the requirement, so long as the hole forming member 50 can be lifted and rotated (the power unit 55 and the third servo motor 56 cooperate) at the same time, and the hole forming member is not particularly limited.

When the processing apparatus 1 is used in a production line, a single object 9 is transported to the edge milling device 3 by one of the pick-and-place components 10 of the transporting device 1a to perform edge milling operation, so that the edge milling device 3 mills burrs on the flanges 91 on the four sides 9c of the object 9.

In this embodiment, by virtue of the design of the cyclic displacement (the moving directions f1, f2, B1, B2 shown in fig. 3B) of the edge milling assembly 3a of the edge milling device 3, the edge milling assembly 3a is prevented from repeatedly milling the flange 91 on the same side 9c, so that the flange 91 on the side 9c of the object 9 is prevented from being damaged due to excessive milling or the edge milling assembly 3a generates mechanical noise.

After finishing the edge milling operation, the object 9 is transported from the edge milling device 3 to the height milling device 2 by the other pick-and-place assembly 10 of the transporting device 1a, so that the height milling device 2 performs the height milling operation (i.e. edge milling) on the four pedestals 90 of the object 9.

Since the front and middle stage milling works are performed on the bottom of the raised floor (the second surface 9b of the target 9), and the later stage drilling works are performed on the top surface of the raised floor (the first surface 9a of the target 9), the raised floor needs to be turned over before the drilling works are performed. Therefore, the object 9 is transported from the milling device 2 to the third positioning member 42 of the turning device 4 by the other pick-and-place component 10 of the transporting device 1a, the shaft structure 40 is turned by the driving member 47 to turn the third positioning member 42 along the shaft structure 40, the object 9 is turned 180 degrees and placed on the third supporting structure 43, and then the third supporting structure 43 is slid into the processing area A1 of the hole forming device 5,5a by the guide rail 45. It should be understood that the object 9 may also be flipped manually.

Finally, the hole forming device 5,5a is used to perform the drilling operation (such as the hole forming 900 shown in fig. 1D) of the countersunk hole at the foot stand 90 of the target object 9, and after the drilling operation is finished, the moving member 57 is used to push the processed target object 8 (such as shown in fig. 1D) to the discharging area A2, so as to complete the processing flow of the whole raised floor.

In summary, the hole forming devices 5,5a of the present invention are mainly configured to combine the power unit 55 and the hole forming member 50 in a straight line, so that the size can be reduced, the production time can be shortened and the production efficiency can be improved, and the labor effort can be reduced. Therefore, the main feature of the present invention is to directly drive the hole forming member 50 by using the power set 55, which not only reduces the volume of the hole forming member 50, but also increases the machining precision and speed by digitally controlling the rotation of the power set 55, which is an efficiency that cannot be achieved by using a general motor drive in the prior art.

Furthermore, the hole forming device 5a of the present invention can lift the plurality of power sets 55 by using the single third servo motor 56, as shown in fig. 5C, not only can lift and rotate the plurality of hole forming members 50 at the same time, so as to improve the processing efficiency, but also can save the cost of the hole forming device 5 a.

The above embodiments are merely illustrative of the principles of the present invention and its effectiveness, and are not intended to limit the invention. Modifications to the above would be obvious to those of ordinary skill in the art, without departing from the spirit and scope of the present invention. The scope of the invention is therefore indicated by the appended claims.
