Description

Technical Field

[0001] This invention relates to the field of tire mold cleaning technology, specifically to an automated tire mold cleaning device. Background Technology

[0002] In the tire manufacturing industry, tire molds are the core tooling for tire production, and the cleanliness of their inner walls directly determines the surface quality of the tire. With the increasing demand for automated production, automated tire mold cleaning equipment is gradually replacing manual cleaning. However, existing equipment has many technical shortcomings in the clamping and positioning process, severely restricting cleaning efficiency and quality. Specific problems are as follows:

[0003] (a) Low mold clamping and positioning accuracy, which easily leads to displacement during the cleaning process and results in cleaning dead zones:

[0004] Existing cleaning equipment often uses either a single-cylinder clamping mechanism or a manual bolt fixing mechanism. The single-cylinder clamping method applies clamping force only from one side of the mold, which can easily lead to mold misalignment due to uneven force distribution (centering error often exceeds 3mm). During cleaning, the mold rotates radially, causing the laser cleaning gun head to fail to accurately align with the inner wall grooves, resulting in incomplete cleaning in certain areas. While manual bolt fixing improves centering accuracy, it requires manual tightening of each bolt, which is cumbersome and time-consuming. Each mold replacement requires 10-15 minutes of adjustment, making it unsuitable for the high-efficiency production demands of automated production lines. Furthermore, some clamping structures do not consider differences in mold diameter, requiring different sizes of clamps to fit different mold models, resulting in poor versatility and increased equipment procurement and maintenance costs.

[0005] (II) After clamping, the laser cleaning gun head still needs to be continuously rotated and adjusted by the industrial robotic arm to achieve circumferential cleaning of the mold's inner wall, affecting the service life of the industrial robotic arm. If a scheme where the mold rotates relative to the laser cleaning gun head is adopted, a separate drive component needs to be set up in addition to the clamping and positioning components, which not only increases equipment investment but also results in large coaxiality deviations when the mold rotates, leading to different distances between the laser cleaning gun head and the inner wall of the mold. In some areas, due to different laser energy, it is insufficient to completely remove residual impurities, and the cleaning effect cannot be guaranteed to be consistent. To address this, we have introduced an automated tire mold cleaning device. Summary of the Invention

[0006] The purpose of this invention is to provide an automated tire mold cleaning device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automated tire mold cleaning device, comprising a control console and a cleaning chamber, wherein a laser cleaning gun assembly is provided on the top of the cleaning chamber, and a movable seat assembly for placing tire molds is provided on the track at the bottom of the cleaning chamber.

[0008] Both the laser cleaning gun assembly and the moving base assembly are controlled by a console, enabling the laser cleaning gun assembly to clean the inner wall of the tire mold.

[0009] The movable seat assembly includes a movable seat, a load-bearing turntable assembly rotatably connected to the upper end of the movable seat, a lifting assembly disposed on the movable seat, and clamping and positioning drive assemblies disposed at equal intervals on the lifting assembly.

[0010] After the tire mold is placed on the upper end of the carrier turntable assembly, the top of the lifting assembly rises into the interior of the tire mold. The clamping and positioning drive assembly is driven by the first power drive component inside the lifting assembly to achieve synchronous opening of the clamping and positioning drive assembly. The contact wheel at the end of the clamping and positioning drive assembly contacts the inner wall of the tire mold to achieve centered clamping and positioning of the tire mold. Subsequently, the contact wheel is driven by the second power drive component on the lifting assembly to achieve rotation of the tire mold.

[0011] Preferably, the track extends through the openings at both ends of the bottom of the cleaning chamber, and dustproof curtains are provided at the openings at both ends of the bottom of the cleaning chamber.

[0012] Preferably, the cleaning chamber is provided with an end cover at the top, and an FFU dust collector is installed on the end cover.

[0013] The laser cleaning gun assembly includes an industrial robotic arm centrally mounted at the lower end of the end cap and a laser cleaning gun head fixed at the end of the industrial robotic arm.

[0014] Preferably, the bottom of the movable seat is provided with an I-shaped roller controlled by a servo motor, and the I-shaped roller sits on the track;

[0015] The top groove at the top of the movable seat is provided with a top plate, and the interior of the movable seat is provided with an installation cavity, with maintenance plates installed on both sides of the installation cavity.

[0016] Preferably, the lifting assembly uses a hydraulic lifting component that is centrally fixed in the mounting cavity for vertical movement;

[0017] The hydraulic lifting component includes a hydraulic cylinder fixed in the center of the mounting cavity, a piston inside the hydraulic cylinder, and a piston rod disposed at the middle of the upper end of the piston.

[0018] The lifting assembly includes a lifting seat fixed to the upper end of the piston rod and a lifting column fixed to the middle of the upper end of the lifting seat.

[0019] Preferably, the top plate is provided with several sets of rollers at equal intervals, and the bearing turntable assembly includes a bearing plate located on the upper end of the several sets of rollers and a limiting post provided at the lower center of the bearing plate;

[0020] The bearing plate and the limiting column are provided with a through hole for passing through the lifting column in the middle;

[0021] The bottom of the limiting post extends through a pre-drilled hole in the middle of the top plate and is screwed with a limiting nut.

[0022] Preferably, the lower end of the lifting seat is connected to a limiting cylinder by a protruding plate, and a vertical limiting rod is also provided in the mounting cavity, with the limiting cylinder sleeved on the corresponding vertical limiting rod.

[0023] Preferably, the clamping and positioning drive assembly includes an arc-shaped I-beam seat that is movably connected to the lifting column at equal intervals using a vertical shaft;

[0024] The first power drive component includes a bottom motor fixed in the center of the slot at the bottom of the lifting column and a bottom gear plate fixedly connected to the bottom shaft at the top output end of the bottom motor. The bottom of the vertical shaft extends into the slot and is connected to a bottom gear. The bottom gear plate meshes with the inner side of several sets of bottom gears.

[0025] Preferably, the contact wheel is movably connected to the notch at the outer end of the arc-shaped I-beam base, and a driven gear is movably connected to the notch at the inner end of the arc-shaped I-beam base, and the driven gear is coaxial with the corresponding vertical shaft;

[0026] A belt is connected between the contact wheel and the pulley in the middle of the driven gear, and a pressure roller for tightly adhering to the belt is also provided on the arc-shaped I-beam base;

[0027] The second power drive component includes a second motor fixed in the mounting groove at the middle of the upper end of the lifting column, a top gear plate fixedly connected to the top shaft at the top output end of the second motor, and several sets of drive gears movably connected at equal intervals to the upper end of the lifting column. The several sets of drive gears mesh with the outer side of the top gear plate, and the drive gears mesh with the inner side of the corresponding driven gear.

[0028] The top of the top gear plate is also provided with a top plate, the diameter of which is the same as the diameter of the lifting column, and the top plate is located above the clamping and positioning drive assembly.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] High-precision centering is achieved through multiple sets of synchronous opening: The arc-shaped I-beams of the clamping and positioning drive components open outwards simultaneously along the circumference, applying uniform clamping force from multiple directions on the inner wall of the tire mold. The centering error is ≤±1mm, which is more than 3 times better than existing equipment. This ensures the relative position of the tire mold and the laser cleaning gun head is stable, avoiding cleaning dead angles caused by eccentricity. At the same time, the opening range of the arc-shaped I-beams is adjustable and controllable, adapting to different specifications of tire molds. There is no need to change the clamps, which greatly improves the equipment's versatility and reduces the equipment investment cost for cleaning multiple specifications of molds.

[0031] It can achieve 360-degree laser cleaning of the inner wall of the tire mold with the laser cleaning gun head, extending the service life of the industrial robotic arm. The clamping and positioning drive component can not only clamp and position the tire mold, but also drive the tire mold to rotate, so that the tire mold will not shift its position when rotating, ensuring that the cleaning effect of the laser cleaning gun head on the inner wall of the tire mold is consistent.

[0032] Multiple sets of curved I-beam supports open to clamp the tire mold from the inside. The laser cleaning gun head extends into the tire mold and faces the inner wall of the tire mold. The laser cleaning gun head is positioned between adjacent curved I-beam supports. In this way, the curved I-beam supports and the laser cleaning gun head are in a stationary state. Then, the contact wheels on the curved I-beam supports drive the tire mold to rotate 360 ​​degrees, so that the tire mold rotates 360 degrees relative to the curved I-beam supports and the laser cleaning gun head. This allows a single laser cleaning gun head to clean the inner wall of the tire mold 360 degrees, and the curved I-beam supports do not interfere with the laser cleaning gun head's cleaning work on the inner wall of the tire mold.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Example

[0054] Please see Figures 1-15 The present invention provides a technical solution:

[0055] An automated tire mold cleaning device includes a control console 6 and a cleaning chamber 1, with a laser cleaning gun assembly installed on the top of the cleaning chamber 1;

[0056] The top of the cleaning chamber 1 is equipped with an end cover 4, and an FFU dust collector 5 is installed on the end cover 4.

[0057] The laser cleaning gun assembly includes an industrial robotic arm 3 centrally mounted on the lower end of the end cap 4 and a laser cleaning gun head 11 fixed to the end of the industrial robotic arm 3.

[0058] The laser cleaning gun head 11 is fixed at the end of the industrial robotic arm 3. The industrial robotic arm 3 has multi-degree-of-freedom (≥6-axis) motion capability, which can flexibly adjust the angle and position of the laser cleaning gun head 11 (positioning accuracy ≤ ±0.1mm), adapting to different models and different inner wall structures of tire molds 8 (such as molds with complex patterns), and achieving cleaning without dead angles. The industrial robotic arm 3 is automatically controlled by a PLC controller according to a preset program, eliminating the need for manual hand operation, avoiding operator exposure to laser radiation, improving operational safety, and ensuring that the cleaning trajectory is consistent each time, with high repeatability of cleaning effect.

[0059] When the PLC controller controls the laser generator inside the laser cleaning gun head 11 to work, the high-energy laser beam (usually a pulsed laser) emitted by the laser cleaning gun head 11 has high energy density characteristics. When the laser beam irradiates the residual impurities (such as vulcanized rubber residue, oil stains, dust, etc.) on the inner wall of the tire mold 8, the following physical effects will occur: On the one hand, the laser energy is absorbed by the surface of the impurities, causing the impurities to instantly heat up to the vaporization temperature (for rubber impurities, the vaporization temperature is about 300-500℃), and the impurities directly change from solid to gaseous state, realizing separation from the inner wall surface of the tire mold 8;

[0060] On the other hand, for impurities with strong adhesion, the shock wave generated by the laser pulse will mechanically peel off the impurities, further ensuring that the impurities are removed from the mold surface.

[0061] High-energy laser beams can be used to clean residual impurities in the grooves on the inner wall surface of the tire mold 8.

[0062] The control console 6 includes a touch screen and a PLC controller built into the touch screen. The PLC controller controls the operation of the FFU dust collector 5. The fan of the FFU dust collector 5 operates to draw the air in the cleaning chamber 1 upwards, and after being filtered by the filter element of the FFU dust collector 5, it is discharged from the cleaning chamber 1, thereby ensuring that the air in the work area where the tire laser cleaning device is installed is in a clean state.

[0063] A movable seat assembly 9 for placing tire mold 8 is provided on the track 10 at the bottom of the cleaning chamber 1;

[0064] The lower front of the cleaning chamber 1 is also equipped with an electric sliding door 7. After the electric sliding door 7 is opened, it is convenient to inspect and maintain the equipment inside the cleaning chamber 1.

[0065] Track 10 extends through the openings at both ends of the bottom of the cleaning chamber 1, and dustproof curtains 2 are installed at the openings at both ends of the bottom of the cleaning chamber 1.

[0066] The bottom of the movable seat 901 is equipped with an I-shaped roller 903 controlled by a servo motor, which sits on the track 10. The servo motor is controlled by a PLC controller, which controls the servo motor to drive the I-shaped roller 903 to roll on the track 10, thereby enabling the movable seat 901 to move along the track 10.

[0067] A top plate 902 is provided in the top groove 912 at the top of the movable base 901, and an installation cavity is provided inside the movable base 901. Inspection plates 904 are installed on both sides of the installation cavity.

[0068] The inspection plate 904 is connected by bolts. When components such as the lifting assembly 909 and the bottom motor 90912 malfunction, the inspection plate 904 can be quickly disassembled for maintenance without disassembling the entire moving seat assembly 9, thus shortening maintenance time and reducing maintenance costs.

[0069] Both the laser cleaning gun assembly and the moving base assembly 9 are controlled by the control console 6, so that the laser cleaning gun assembly can be used to clean the inner wall of the tire mold 8.

[0070] The movable seat assembly 9 includes a movable seat 901, a bearing turntable assembly rotatably connected to the upper end of the movable seat 901, a lifting assembly 909 disposed on the movable seat 901, and clamping and positioning drive assemblies 90909 disposed at equal intervals on the lifting assembly 909.

[0071] The lifting assembly 909 uses a hydraulic lifting component that is centrally fixed in the mounting cavity to move up and down;

[0072] The hydraulic lifting component includes a hydraulic cylinder 910 fixed in the center of the mounting cavity, a piston 90905 inside the hydraulic cylinder 910, and a piston rod 90904 set at the middle of the upper end of the piston 90905;

[0073] The lifting assembly 909 includes a lifting seat 90901 fixed to the upper end of the piston rod 90904 and a lifting column 90906 fixed to the middle of the upper end of the lifting seat 90901.

[0074] The PLC controller controls the operation of the hydraulic oil pump to connect the hydraulic oil with the hydraulic cylinder 910, thereby controlling the extension or retraction of the piston rod 90904 to achieve the lifting and lowering of the lifting assembly 909.

[0075] The lower end of the lifting seat 90901 is connected to a limiting cylinder 90903 via a protruding plate 90902. A vertical limiting rod 911 is also provided inside the mounting cavity, and the limiting cylinder 90903 is sleeved on the corresponding vertical limiting rod 911. This arrangement serves to limit the vertical movement of the lifting assembly 909, ensuring that the lifting assembly 909 is always in a vertical lifting position.

[0076] In normal use, the tire mold 8 is placed directly on the top plate 902. As the tire mold 8 rotates, friction will cause wear on the bottom of the tire mold 8.

[0077] The top plate 902 is provided with several sets of rollers 907 at equal intervals. The bearing turntable assembly includes a bearing plate 905 located on the upper end of the several sets of rollers 907 and a limiting post 906 provided at the lower middle part of the bearing plate 905.

[0078] The middle part of the bearing plate 905 and the limiting column 906 is provided with a through hole 908 for passing through the lifting column 90906;

[0079] The bottom of the limiting post 906 extends through the pre-drilled hole 913 in the middle of the top plate 902 and is screwed with a limiting nut 914. This arrangement allows the bearing turntable assembly to rotate, and since the bearing plate 905 sits on top of several sets of rollers 907, it can drive the bearing plate 905 to rotate together when the tire mold 8 rotates, thus preventing wear on the bottom of the tire mold 8 when it rotates.

[0080] The clamping and positioning drive assembly 90909 includes an arc-shaped I-beam base 909091 that is movably connected to the lifting column 90906 at equal intervals via a vertical shaft 909095;

[0081] The first power drive component includes a bottom motor 90912 fixed in the center of the slot at the bottom of the lifting column 90906, and a bottom gear 90907 fixedly connected to the bottom shaft 90915 at the top output end of the bottom motor 90912. The bottom of the vertical shaft 909095 extends into the slot and is connected to a bottom gear 90908. The bottom gear 90907 meshes with the inner side of several sets of bottom gears 90908.

[0082] The arc-shaped I-beam base 909091 is movably connected to the lifting column 90906 via the vertical shaft 909095. The bottom gear plate 90907 simultaneously meshes with all the bottom gears 90908, causing multiple sets of arc-shaped I-beam bases 909091 to move outward or inward simultaneously, achieving centered clamping of the tire mold 8 (centering error ≤ ±1mm), avoiding mold eccentricity caused by traditional "single-set adjustment". The contact wheel 909092 is made of elastic rubber, which can produce slight deformation when in contact with the inner wall of the tire mold 8, increasing the contact area, ensuring firm clamping, avoiding scratches on the inner wall of the mold, and protecting the installation accuracy of the tire mold 8.

[0083] The contact wheel 909092 is movably connected to the notch at the outer end of the arc-shaped I-beam 909091. The driven gear 909094 is movably connected to the notch at the inner end of the arc-shaped I-beam 909091, and the driven gear 909094 is coaxial with the corresponding vertical shaft 909095.

[0084] A belt 909093 is connected between the pulley in the middle of the contact wheel 909092 and the driven gear 909094. The arc-shaped I-beam seat 909091 is also provided with a pressure roller 909096 for tightly adhering to the belt 909093.

[0085] The second power drive component includes a second motor 90916 fixed in the mounting groove 90917 in the middle of the upper end of the lifting column 90906, a top gear disk 90911 fixedly connected to the top shaft 90914 at the top output end of the second motor 90916, and several sets of drive gears 90913 movably connected at equal intervals to the upper end of the lifting column 90906. The several sets of drive gears 90913 mesh with the outer side of the top gear disk 90911, and the drive gears 90913 mesh with the inner side of the corresponding driven gears 909094.

[0086] Both the first power drive component (bottom motor 90912, bottom gear 90907) and the second power drive component (second motor 90916, top gear 90911) adopt a "single motor-gear 90911-multiple gear" transmission structure, which allows a single motor to drive multiple components to move synchronously, simplifying the equipment structure and reducing energy consumption.

[0087] At the same time, the pressure roller 909096 is in close contact with the belt 909093 to prevent belt slippage and ensure that the contact wheel 909092 rotates at a stable speed, thereby ensuring that the tire mold 8 rotates at a uniform speed (speed fluctuation ≤ ±5%), providing stable circumferential feeding conditions for laser cleaning.

[0088] The contact wheel 909092 is made of elastic rubber. When it comes into contact with the inner wall of the tire mold 8, it can produce a slight deformation of 0.5-1mm. This increases the contact area (50% more than the contact area of ​​the rigid clamping block) to ensure a firm clamping, while also preventing rigid collisions from scratching the inner wall of the tire mold 8. This protects the surface roughness of the tire mold 8 (Ra value ≤ 0.8μm) and extends the service life of the tire mold 8 (more than 20% longer than the service life of existing equipment).

[0089] After the tire mold 8 is placed on the upper end of the carrier turntable assembly, the top of the lifting assembly 909 rises into the interior of the tire mold 8. The clamping and positioning drive assembly 90909 is driven by the first power drive component inside the lifting assembly 909, realizing the synchronous opening of the clamping and positioning drive assembly 90909. The contact wheel 909092 at the end of the clamping and positioning drive assembly 90909 contacts the inner wall of the tire mold 8 to achieve centered clamping and positioning of the tire mold 8. Subsequently, the contact wheel 909092 is driven by the second power drive component on the lifting assembly 909 to realize the rotation of the tire mold 8.

[0090] The top of the top gear plate 90911 is also provided with a top plate 90910, the diameter of which is the same as the diameter of the lifting column 90906. The top plate 90910 is located above the clamping and positioning drive assembly 90909. In this way, after the clamping and positioning drive assembly 90909 is closed synchronously, it can be completely retracted into the space between the top plate 90910 and the lifting column 90906. When placing or removing the tire mold 8, the clamping and positioning drive assembly 90909 is prevented from blocking the tire mold 8, and the tire mold 8 is also prevented from impacting the clamping and positioning drive assembly 90909.

[0091] Specifically, when using it:

[0092] The operator places the tire mold 8 to be cleaned on the carrier turntable assembly of the moving seat assembly 9. The carrier plate 905 of the carrier turntable assembly sits on the roller 907 of the top plate 902, and the tire mold 8 is placed on the upper end of the carrier plate 905.

[0093] The PLC controller controls the hydraulic oil pump to inject hydraulic oil into the hydraulic cylinder 910, pushing the piston 90905 to move upward. The piston 90905 drives the piston rod 90904 to extend, thereby pushing the lifting seat 90901 and the lifting column 90906 to rise synchronously. The limiting cylinder 90903 at the lower end of the lifting seat 90901 is sleeved on the vertical limiting rod 911 to ensure that the lifting assembly 909 rises stably in the vertical direction until the lifting column 90906 penetrates the through hole 908 in the middle of the bearing plate 905 and the limiting column 906 and extends into the tire mold 8.

[0094] The clamping and positioning drive assembly 90909 opens synchronously: The PLC controller starts the bottom motor 90912 of the first power drive component. The bottom motor 90912 drives the bottom shaft 90915 and the bottom gear 90907 to rotate. The bottom gear 90907 meshes with the inner side of several sets of bottom gears 90908, driving the bottom gears 90908 and the vertical shaft 909095 to rotate synchronously. The vertical shaft 909095 drives the arc-shaped I-beam 909091 to open outward around the vertical shaft 909095 until the contact wheel 909092 at the outer end of the arc-shaped I-beam 909091 is tightly attached to the inner wall of the tire mold 8, realizing the centered clamping and positioning of the tire mold 8 and preventing the tire mold 8 from shifting during the cleaning process. Tire mold 8 rotation drive: After clamping and positioning, the PLC controller starts the second motor 90916 of the second power drive component. The second motor 90916 drives the top shaft 90914 and the top gear disk 90911 to rotate. The top gear disk 90911 meshes with the outer side of several sets of drive gears 90913, driving the drive gears 90913 to rotate. The drive gears 90913 mesh with the inner side of the driven gears 909094, driving the driven gears 909094 and the pulleys on the inner side of the arc-shaped I-beam seat 909091 to rotate. The pulleys drive the contact wheel 909092 to rotate through the belt 909093. The friction between the contact wheel 909092 and the inner wall of the tire mold 8 drives the tire mold 8 and the support plate 905 to rotate synchronously (the support plate 905 sits on the drum 907 to reduce rotational friction), providing full circumferential coverage for laser cleaning.

[0095] A "transfer command" is sent via the touch screen of console 6. After receiving the command, the PLC controller starts the servo motor at the bottom of the moving base 901. The servo motor drives the I-shaped roller 903 to roll on the track 10, moving the moving base 901 along the track 10 into the cleaning chamber 1. When the moving base 901 reaches the preset cleaning position in the cleaning chamber 1, the servo motor stops working, completing the mold transfer.

[0096] Laser cleaning gun assembly startup: The PLC controller controls the industrial robotic arm 3 to start, and the industrial robotic arm 3 drives the laser cleaning gun head 11 at the end to move along a preset trajectory (adapted to the inner wall structure of the tire mold 8); the laser cleaning gun head 11 emits laser to precisely clean the residual rubber, oil and other impurities on the inner wall of the tire mold 8. The laser energy causes the impurities to vaporize or peel off instantly, avoiding damage to the mold surface caused by traditional cleaning methods.

[0097] When performing laser cleaning on the inner wall of the tire mold 8, the tire mold 8 rotates, which enables the laser cleaning gun head 11 to perform 360-degree laser cleaning on the inner wall of the tire mold 8.

[0098] Real-time dust removal and purification: At the same time as the laser cleaning is started, the PLC controller controls the FFU dust collector 5 to work. The fan of the FFU dust collector 5 draws the air in the cleaning chamber 1 upward. Impurities in the air (such as vaporized rubber particles and dust) are filtered by the filter element of the FFU dust collector 5, and clean air is discharged from the cleaning chamber 1, ensuring that the air in the cleaning chamber 1 and the work area is clean and avoiding secondary contamination of the mold by impurities or harm to the health of the operators.

[0099] After the inner wall of the tire mold 8 is cleaned, the PLC controller sequentially shuts down the laser cleaning gun head 11, the second motor 90916, and the bottom motor 90912, and controls the hydraulic oil pump to work in reverse, so that the hydraulic oil in the hydraulic cylinder 910 flows back. The piston rod 90904 drives the lifting assembly 909 and the clamping and positioning drive assembly 90909 to descend and reset, and the contact wheel 909092 disengages from the inner wall of the tire mold 8.

[0100] The PLC controller controls the servo motor at the bottom of the moving seat 901 to start in reverse, driving the I-shaped roller 903 to roll along the track 10, conveying the moving seat 901 and the cleaned tire mold 8 out of the cleaning chamber 1. The operator removes the mold, completing one cleaning cycle. If continuous cleaning is required, the above process can be repeated to place the next set of tire molds 8 to be cleaned.

[0101] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
