Description

Technical Field

[0001] This invention relates to the field of sheet metal processing equipment, and more particularly to a handle-free sheet metal gluing mechanism and a sheet metal edge sealing method having the same. Background Technology

[0002] The existing board material uses a handle-free design with a groove on its right side, resulting in a structure on the right side comprising a lower vertical section, a horizontal section, a contact section, and an upper vertical section. Currently, the groove on the existing board requires edge banding tape. During application, adhesive is first applied to the edge banding tape, which is then pressed onto the lower, horizontal, contact, and upper vertical sections. However, existing board processing equipment lacks a dedicated adhesive application structure for the upper vertical section. During the pressing process, some of the adhesive on the edge banding tape corresponding to the upper vertical section is scraped off by the pressing structure, preventing the edge banding tape from adhering securely to the upper vertical section. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a handle-free board gluing mechanism and a board edge sealing method having the same.

[0004] According to a first aspect of the present invention, a handle-free board gluing mechanism includes a mounting base, a gluing assembly, and a first driving device. The gluing assembly includes a glue tank, a first opening and closing member, and a gluing roller. The glue tank is movably mounted on the mounting base and has a glue inlet and a glue outlet. The first opening and closing member is mounted at the glue outlet and is capable of opening or closing the glue outlet. The gluing roller is rotatably mounted on the glue tank and located on the side of the first opening and closing member away from the glue tank. The first driving device is mounted on the mounting base and connected to the glue tank. The first driving device is capable of driving the glue tank to move left and right.

[0005] Furthermore, the glue box has a glue dispensing channel from the glue inlet to the glue outlet, and a movable second opening and closing member is installed in the glue dispensing channel, the second opening and closing member being located between the glue inlet and the glue outlet;

[0006] The second opening and closing member can move between a first position and a second position. In the first position, the glue inlet is connected to the glue outlet. In the second position, the second opening and closing member blocks the glue inlet from communicating with the glue outlet.

[0007] Furthermore, at least a portion of the second opening and closing member is rotatably installed in the glue dispensing channel. The second opening and closing member has a communicating cavity, which communicates with the glue dispensing channel between the second opening and closing member and the glue dispensing port. The outer side wall of the second opening and closing member has a communicating hole communicating with the communicating cavity, and the position of the communicating hole corresponds to the position of the glue inlet.

[0008] When the second opening / closing member is rotated to the first position, the connecting hole communicates with the glue inlet;

[0009] When the second opening / closing member is rotated to the second position, the position of the connecting hole is offset from the position of the glue inlet, and the outer wall of the second opening / closing member closes the glue inlet.

[0010] Furthermore, the second opening and closing member extends to the outside of the glue box and is connected to a connecting block;

[0011] The handle-free board gluing mechanism also includes a first cylinder, which is an adjustable stroke cylinder. The fixed seat of the first cylinder is rotatably connected to the glue box, and the first extension rod of the first cylinder is rotatably connected to the connecting block. The rotatable connection point between the first extension rod and the connecting block is eccentrically positioned relative to the center of the connecting block.

[0012] Furthermore, it also includes a support assembly, which is movably mounted on the mounting base. The support assembly is connected to the first drive device. A second cylinder is mounted on the support assembly. The glue box is movably mounted on the support assembly and located to the left of the second cylinder. The second extension rod of the second cylinder is connected to the glue box.

[0013] Furthermore, the support assembly includes a first fixed seat and a second fixed seat. The first fixed seat is movably mounted on the mounting base and is connected to the first driving device. The second fixed seat is movably mounted on the first fixed seat. The glue box and the second cylinder are mounted on the second fixed seat. The first fixed seat is equipped with a third cylinder, and the third extension rod of the third cylinder is connected to the second fixed seat.

[0014] The first fixing seat is threaded with a screw, which passes upward through the second fixing seat, with the head of the screw positioned above the second fixing seat.

[0015] Furthermore, the glue box has an opening and closing cavity located to the left of the glue outlet. The left and right sides of the opening and closing cavity are respectively connected to the outside of the glue box and the glue outlet. The first opening and closing component is rotatably installed in the opening and closing cavity. The outer wall of the first opening and closing component includes several straight surfaces and an arc surface that can close the glue outlet. The arc surface abuts against the inner wall of the opening and closing cavity.

[0016] Furthermore, the first driving device is a servo motor, which is connected to the glue box via a transmission connection.

[0017] The handle-free panel gluing mechanism according to the present invention has at least the following technical advantages:

[0018] 1. The glue-applying roller is positioned on one side of the first opening and closing component. The first opening and closing component can open the glue outlet, allowing the glue on the outlet to flow onto the glue-applying roller. At the same time, the first driving device can drive the glue box to move left and right. Therefore, even if part of the upper vertical section is curved, the first driving device can still drive the glue-applying roller to abut against the upper vertical section of the board, thereby allowing the glue-applying roller to apply glue onto the upper vertical section, thus preventing the edge banding tape from failing to adhere firmly to the upper vertical section.

[0019] 2. The first cylinder is a stroke adjustable cylinder, which can pre-adjust the stroke of the first extension rod so that when the first extension rod is fully extended, the second opening and closing member rotates to the first position, and when the first extension rod is fully retracted, the second opening and closing member rotates to the second position, which simplifies the structure of driving the second opening and closing member to rotate.

[0020] According to a second aspect of the present invention, a method for sealing the edge of a board is used to press the edge sealing tape onto the right side of a board, wherein the right side of the board has a groove, the groove comprising a horizontal section, a contact section and an upper vertical section connected sequentially from bottom to top, characterized in that it includes a handle-free board gluing mechanism, a gluing mechanism and a pressing mechanism according to the first aspect of the present invention.

[0021] It also includes the following steps:

[0022] S1, the handle-free board glue application mechanism applies glue to the upper vertical section;

[0023] S2, the glue application mechanism applies glue to the edge sealing tape;

[0024] S3, the pressing mechanism presses the edge banding tape after applying glue onto the right side of the board.

[0025] The edge-sealing method for sheet metal according to the present invention has at least the following technical effects:

[0026] 1. By providing the handle-free board gluing mechanism of the first aspect embodiment, glue is applied to the upper vertical section of the board and then the edge banding is pressed on, thereby making the edge banding more firmly attached to the right side of the board.

[0027] Furthermore, S1 includes: S11, the first driving device drives the glue box to move left and right relative to the board, so that when the board moves relative to the glue roller, the glue roller is in close contact with the upper vertical section and applies glue to the upper vertical section.

[0028] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0042] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0043] Reference Figure 1 , 2 As shown, the handle-free board gluing mechanism of the first aspect embodiment of the present invention includes a mounting base 100, a gluing assembly 200, and a first driving device 600. The gluing assembly 200 includes a glue tank 300, a first opening and closing member 400, and a gluing roller 500. The glue tank 300 is movably mounted on the mounting base 100 and has a glue inlet 310 and a glue outlet 320. The first opening and closing member 400 is mounted at the glue outlet 320 and can open or close the glue outlet 320. The gluing roller 500 is rotatably mounted on the glue tank 300 and is located on the side of the first opening and closing member 400 away from the glue tank 300 (located on the left side of the first opening and closing member 400). The first driving device 600 is mounted on the mounting base 100 and connected to the glue tank 300. The first driving device 600 can drive the glue tank 300 to move left and right.

[0044] The glue-applying roller 500 is positioned on one side of the first opening and closing member 400. The first opening and closing member 400 can open the glue outlet 320, allowing the glue on the glue outlet 320 to flow onto the glue-applying roller 500. At the same time, the first driving device 600 can drive the glue tank 300 to move left and right. Therefore, even if part of the upper vertical section 930 is arc-shaped, the first driving device 600 can still drive the glue-applying roller 500 to abut against the upper vertical section 930 of the board 900, thereby allowing the glue-applying roller 500 to apply glue onto the upper vertical section 930, thus preventing the edge banding tape from failing to adhere firmly to the upper vertical section 930.

[0045] It is understandable that the handle-free board gluing mechanism can adapt to upper vertical sections 930 of different shapes. For example, the upper vertical section 930 may extend entirely along a straight line in the front-to-back direction, or the upper vertical section 930 may include an extension section 931 and an arc section 932 arranged sequentially in the front-to-back direction (e.g., Figure 3 (as shown), or the upper vertical segment 930 includes a first arc segment, an extension segment, and a second arc segment arranged sequentially along the front-back direction, or other shapes;

[0046] like Figure 3 As shown, taking the vertical segment 930 above as an example, which includes an extension segment 931 and an arc segment 932 arranged sequentially in the front-back direction, the right side of the plate 900 has a groove 910. The right side of the plate 900 includes a lower vertical segment 940, a horizontal segment 911, a contact segment 920 and an upper vertical segment 930 connected sequentially from bottom to top. The upper vertical segment 930 includes an extension segment 931 and an arc segment 932 connected sequentially from front to back. The extension segment 931 extends in the front-back direction. Both the extension segment 931 and the arc segment 932 are located to the left of the lower vertical segment 940.

[0047] Before operation, the sheet material 900 is placed on the conveyor (not shown in the figure), such as... Figure 4 As shown, the glue roller 500 is positioned to the right of the upper vertical section 930. The first drive device 600 drives the glue tank 300 to move to the left relative to the mounting base 100. The glue tank 300 drives the glue roller 500 to move to the left, so that when the board 900 passes through the glue roller 500, the outer wall of the glue roller 500 can abut against the extension section 931. At the same time, the first opening and closing member 400 opens the glue outlet 320, and the glue on the glue outlet 320 flows onto the glue roller 500.

[0048] During operation, the glue-applying roller 500 rotates, and the conveying device drives the sheet 900 forward to successively extend the section 931 and the arc section 932. When the extension section 931 passes the glue-applying roller 500, the glue on the outer wall of the glue-applying roller 500 is applied to the extension section 931. After the extension section 931 is applied, since the arc section 932 is arc-shaped, the first driving device 600 drives the glue box 300 to move to the right relative to the mounting base 100. In coordination with the forward movement of the sheet 900, the glue-applying roller 500 keeps in contact with the arc section 932 and applies glue to the arc section 932.

[0049] Furthermore, such as Figure 2 As shown, the glue box 300 has a glue dispensing channel 330 from the glue inlet 310 to the glue outlet 320. A movable second opening and closing member 340 is installed in the glue dispensing channel 330, and the second opening and closing member 340 is located between the glue inlet 310 and the glue outlet 320.

[0050] The second opening / closing member 340 can move between a first position and a second position. In the first position, the glue inlet 310 is connected to the glue outlet 320. In the second position, the second opening / closing member 340 blocks the glue inlet 310 from connecting to the glue outlet 320.

[0051] The second opening and closing element 340 controls whether the glue inlet 310 and the glue outlet 320 are connected, and the first opening and closing element 400 can also control whether the glue outlet 320 dispenses glue. Thus, when the glue is not in use, the glue in the glue box 300 can not come into contact with the outside air, thereby avoiding the glue in the glue box 300 from reacting with the air and affecting the glue application.

[0052] When glue is needed, the first opening and closing member 400 opens the glue outlet 320, and the second opening and closing member 340 moves to the first position. The external glue enters the glue outlet channel 330 through the glue inlet 310, and then flows from the glue outlet 320 onto the glue coating roller 500.

[0053] When glue is not needed, the first opening / closing member 400 closes the glue outlet 320, and the second opening / closing member 340 moves to the second position.

[0054] Specifically, a heating element is installed inside the glue box 300, which can heat the glue in the glue dispensing channel 330 to prevent the glue from cooling and solidifying.

[0055] Specifically, the first driving device 600 is a servo motor. The servo motor drives the glue-applying roller 500 to abut against the upper vertical section 930 of the board 900. Using a servo motor allows the glue-applying roller 500 to move left and right following the shape of the upper vertical section 930, ensuring that the glue-applying roller 500 abuts against the entire upper vertical section 930, so that the entire upper vertical section 930 is coated with glue. For example, as... Figure 8 As shown, the upper vertical section 930 includes an extension section 931 and two arc sections 932. In the front-back direction, the extension section 931 is located between the two arc sections 932. When the glue-applying roller 500 passes the front arc section 932, the servo motor drives the glue-applying roller 500 to move to the left according to the shape of the front arc section 932. When the glue-applying roller 500 passes the rear arc section 932, the servo motor drives the glue-applying roller 500 to move to the right according to the shape of the rear arc section 932, thereby ensuring that the glue-applying roller 500 abuts against the entire upper vertical section 930.

[0056] Furthermore, such as Figure 2 , 5As shown, at least a portion of the second opening / closing member 340 is rotatably mounted in the glue dispensing channel 330. The second opening / closing member 340 has a communicating cavity 341, which communicates with the glue dispensing channel 330 between the second opening / closing member 340 and the glue dispensing port 320. The outer wall of the second opening / closing member 340 has a communicating hole 342 that communicates with the communicating cavity 341. The position of the communicating hole 342 corresponds to the position of the glue inlet 310.

[0057] When the second opening / closing member 340 is rotated to the first position, the connecting hole 342 is connected to the glue inlet 310.

[0058] like Figure 5 As shown, when the second opening / closing member 340 is rotated to the second position, the position of the connecting hole 342 is offset from the position of the glue inlet 310, and the outer wall of the second opening / closing member 340 closes the glue inlet 310.

[0059] The second opening and closing component 340 adopts the above-described configuration to control whether the connecting hole 342 is connected to the glue inlet 310. Simply rotate the second opening and closing component 340 for easy control. During the rotation of the second opening and closing component 340, the hardened glue at the glue inlet 310 can be scraped off through the connecting hole 342 to avoid blockage.

[0060] When glue needs to be applied, the second opening and closing member 340 rotates to the first position, the connecting hole 342 is aligned with the glue inlet 310, and the connecting hole 342 is connected to the glue inlet 310. The external glue passes through the glue inlet 310, the connecting hole 342, the connecting cavity 341, and the glue outlet channel 330 in sequence, and is then discharged from the glue outlet 320.

[0061] When no glue is needed, the second opening / closing member 340 rotates to the second position, the position of the connecting hole 342 is offset from the position of the glue outlet 320, and the outer wall of the second opening / closing member 340 closes the glue inlet 310.

[0062] By providing a second opening / closing element 340, the connection between the glue inlet 310 and the glue outlet 320 can be controlled, allowing the glue inlet 310 to connect with glue supply equipment storing different colors. Furthermore, the first opening / closing element 400 and the second opening / closing element 340 can be controlled independently, enabling more precise control of the glue volume in the glue tank 300. For example, when the glue outlet 320 requires a larger glue output for rapid application, the first opening / closing element 400 fully opens the glue outlet 320, correspondingly connecting the connecting hole 342 completely to the glue outlet 320, increasing the glue inflow to ensure that the glue volume in the glue tank 300 does not decrease due to excessively rapid glue output. Conversely, when the glue output from the glue outlet 320 decreases, the first opening / closing element 400 only opens a portion of the glue outlet 320, also connecting a portion of the connecting hole 342 to the glue outlet 320, preventing glue accumulation in the glue tank 300.

[0063] It is understandable that the glue inlet 310 is connected to the glue supply equipment outside the glue tank 300. The glue outlet 330 can be controlled to be connected to the glue supply equipment by driving the second opening and closing member 340 to rotate. That is, the second opening and closing member 340 is equivalent to a valve. The second opening and closing member 340 is set inside the glue tank 300, so that the glue application mechanism is small in size.

[0064] Specifically, there are two glue inlets 310 and two opening / closing parts 340, so that the two glue inlets 310 can be connected to glue of different colors.

[0065] Specifically, such as Figure 2 As shown, the glue dispensing channel 330 includes a first channel 331 and a second channel 332. The first channel 331 extends in the left-right direction, and the second channel 332 extends in the front-back direction. The second channel 332 has two glue inlets 310 spaced apart in the front-back direction. The right end of the first channel 331 is connected to the second channel 332. The connection between the first channel 331 and the second channel 332 is located between the two glue inlets 310. The left end of the second channel 332 is provided with a glue outlet 320. At least a portion of the two second opening and closing members 340 are respectively inserted into the front and back ends of the second channel 332.

[0066] When adhesive needs to be applied, rotate the second opening / closing member 340 located at the front or the second opening / closing member 340 located at the rear.

[0067] Furthermore, such as Figure 1 , 2 As shown, the second opening / closing member 340 extends to the outside of the plastic box 300 and is connected to the connecting block 350;

[0068] The handle-free board gluing mechanism also includes a first cylinder 700, which is a stroke adjustable cylinder. The fixed seat of the first cylinder 700 is rotatably connected to the glue box 300. The first extension rod 710 of the first cylinder 700 is rotatably connected to the connecting block 350. The rotatable connection between the first extension rod 710 and the connecting block 350 is eccentrically set relative to the center of the connecting block 350.

[0069] The first cylinder 700 is a stroke-adjustable cylinder, which can pre-adjust the stroke of the first extension rod 710 so that when the first extension rod 710 is fully extended, the second opening and closing member 340 rotates to the first position, and when the first extension rod 710 is fully retracted, the second opening and closing member 340 rotates to the second position, which simplifies the structure of driving the second opening and closing member 340 to rotate.

[0070] Specifically, such as Figure 7 As shown, the hinge point between the mounting base of the first cylinder 700 and the plastic box 300 is at point α.

[0071] Furthermore, such as Figure 1As shown, it also includes a support assembly 800, which is movably mounted on the mounting base 100. The support assembly 800 is connected to the first drive device 600. A second cylinder 810 is mounted on the support assembly 800. The glue box 300 is movably mounted on the support assembly 800 and is located to the left of the second cylinder 810. The second extension rod of the second cylinder 810 is connected to the glue box 300.

[0072] A second cylinder 810 is connected to the right side of the glue tank 300. The second cylinder 810 contains compressible gas, which makes the glue application roller 500 and the board 900 in elastic contact, thus preventing the glue application roller 500 from crushing the board 900.

[0073] When it is necessary to move the glue box 300, the first driving device 600 drives the support assembly 800 to move, and the support assembly 800 drives the glue box 300 to move.

[0074] Furthermore, such as Figure 1 As shown, the support assembly 800 includes a first fixed seat 820 and a second fixed seat 830. The first fixed seat 820 is movably mounted on the mounting base 100 and is connected to the first drive device 600. The second fixed seat 830 is movably mounted on the first fixed seat 820. The glue box 300 and the second cylinder 810 are mounted on the second fixed seat 830. The first fixed seat 820 is equipped with a third cylinder 840, and the third extension rod 841 of the third cylinder 840 is connected to the second fixed seat 830.

[0075] The first fixing seat 820 is threadedly connected to a screw 850, which passes upward through the second fixing seat 830, with the head 851 of the screw 850 located above the second fixing seat 830.

[0076] By providing a third cylinder 840 to drive the second fixed seat 830 to move up and down, the second fixed seat 830 can drive the glue box 300 to move up and down, thereby adjusting the up and down position of the glue roller 500 to accommodate boards 900 of different thicknesses; since the screw 850 passes upward through the second fixed seat 830, the screw 850 does not affect the up and down movement of the second fixed seat 830; and since the head 851 of the screw 850 is located above the second fixed seat 830, the head 851 can block the second fixed seat 830 from moving upward, that is, by adjusting the up and down position of the screw 850, the maximum height of the second fixed seat 830 can be adjusted.

[0077] The third cylinder 840 is used in conjunction with the screw 850 to simplify the design of the drive up and down movement structure and the limit structure.

[0078] Specifically, the first fixed seat 820 is mounted on the mounting base 100 in a way that allows it to move left and right via a slider and a guide rail. A guide post and a guide sleeve are provided between the first fixed seat 820 and the second fixed seat 830 to guide the second fixed seat 830 to move up and down.

[0079] Furthermore, such as Figure 2 , 6 As shown, the glue box 300 has an opening and closing cavity 301 located to the left of the glue outlet 320. The left and right sides of the opening and closing cavity 301 are connected to the outside of the glue box 300 and the glue outlet 320, respectively. The first opening and closing member 400 is rotatably installed in the opening and closing cavity 301. The outer wall of the first opening and closing member 400 includes several straight surfaces 410 and an arc surface 420 that can close the glue outlet 320. The arc surface 420 abuts against the inner wall of the opening and closing cavity 301.

[0080] The outer wall of the first opening and closing member 400 includes several straight surfaces 410 and an arc surface 420 that can close the glue outlet 320. The degree to which the arc surface 420 covers the glue outlet 320 can be adjusted by rotating the first opening and closing member 400, thereby controlling the glue dispensing amount and realizing the opening and closing of the glue outlet 320.

[0081] For example, the arc surface 420 only covers part of the glue outlet 320, so the glue discharged from the glue outlet 320 can be discharged out of the opening and closing cavity 301 through the channel between the straight surface 410 and the inner wall of the opening and closing cavity 301, and flow onto the glue coating roller 500.

[0082] Furthermore, such as Figure 7 As shown, the first opening and closing member 400 extends out of the glue box 300 at one end away from the closed cavity 301 (the upper end of the first opening and closing member 400 extends out of the glue box 300) and is connected to a rotating block 430. A fourth cylinder 440 is installed on one side of the rotating block 430. The fourth cylinder 440 is mounted on the glue box 300. The fourth extension rod 441 of the fourth cylinder 440 is rotatably connected to the rotating block 430. The rotatable connection point between the fourth extension rod 441 and the rotating block 430 is eccentrically set relative to the center of the rotating block 430. A movable blocking member 450 is installed on the other side of the rotating block 430 to prevent the rotating block 430 from rotating.

[0083] The blocking member 450 is movable so that the position of the blocking member 450 can be pre-adjusted so that when the fourth extension rod 441 extends and is blocked by the blocking member 450, the arc surface 420 only covers part of the dispensing nozzle 320 or fully opens the dispensing nozzle 320, and when the fourth extension rod 441 is fully retracted, the arc surface 420 completely covers the dispensing nozzle 320.

[0084] Specifically, the fixing part of the fourth cylinder 440 is rotatably mounted on the plastic box 300.

[0085] Specifically, the blocking component 450 is a screw, which is movably mounted on the top of the glue box 300 via a bracket. The rotating block 430 and the fourth cylinder 440 are both located on the top of the glue box 300, which facilitates the installation of the rotating block 430, the blocking component 450, and the fourth cylinder 440.

[0086] Furthermore, such as Figure 1 As shown, the first driving device 600 is a motor, and a rotatable lead screw 110 is mounted on the mounting base 100. The lead screw 110 is threadedly connected to the first fixed base 820, and the motor shaft is fixedly connected to the lead screw 110.

[0087] A lead screw 110 is used in conjunction with a motor to drive the glue application roller 500 to move, so as to precisely control the distance of the glue application roller 500 to move left and right, and avoid damaging the board 900.

[0088] Specifically, the motor is a servo motor.

[0089] The edge sealing method for a board 900 according to a second aspect of the present invention is used to press an edge sealing tape onto the right side of the board 900. The right side of the board 900 has a groove 910, which includes a horizontal section 911, a contact section 920 and an upper vertical section 930 connected sequentially from bottom to top. It includes the handle-free board gluing mechanism, gluing mechanism (not shown in the figure) and pressing mechanism (not shown in the figure) according to the first aspect of the present invention.

[0090] It also includes the following steps:

[0091] S1, the handle-free board glue application mechanism applies glue to the upper vertical section 930;

[0092] S2, The glue application mechanism applies glue to the edge banding tape;

[0093] S3, the pressing mechanism presses the edge banding tape after applying glue onto the right side of the board at 900.

[0094] By providing the handle-free board gluing mechanism of the first aspect embodiment, glue is applied to the upper vertical section 930 of the board 900 and then the edge banding is pressed on, thereby making the edge banding more firmly attached to the right side of the board 900.

[0095] Specifically, the pressing mechanism presses the sealing tape onto the lower vertical section 940, the horizontal section 911, the contact section 920, and the upper vertical section 930 in sequence.

[0096] Furthermore, S1 includes:

[0097] S11, the first driving device 600 drives the glue box 300 to move left and right relative to the board 900, so that when the board 900 moves relative to the glue roller 500, the glue roller 500 is in close contact with the upper vertical section 930 and applies glue to the upper vertical section 930.

[0098] Make sure the entire upper vertical section 930 is coated with glue, and ensure that the edge banding tape is firmly attached to the upper vertical section 930.

[0099] Although the technical solutions of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these technical solutions without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
