Description

Technical Field

[0001] The invention relates to the technical field of inner tube punching, in particular to inner tube production and manufacturing equipment with a continuous punching function and a manufacturing process. Background Art

[0002] The inner tube is an important component of the tire. The manufacturing process of the inner tube is usually as follows: mixing, refining, filtering, extrusion, cooling, punching, cutting, jointing, vulcanization, and inflation testing.

[0003] Generally, in inner tube production factories, punching is one of the most important steps. The quality of the punching determines whether the tire will leak. Generally, when punching, the factory chooses to punch holes in the upper layer of the inner tube, and controls the depth of the punching to ensure that the lower layer will not be punched through. However, when the blade is cutting, it is inevitable that it will come into contact with the lower layer of the inner tube. Even if it is not punched through, the inner tube will be slightly worn. This will reduce the service life of the inner tube and affect the molding quality. At the same time, when the blade is worn, it is easy to cause incomplete cutting, which affects the quality of the later installation of the air nozzle. Moreover, when the factory punches holes, it can control the position of the holes in the inner tubes of the same batch, but when changing to another batch of inner tubes, it is necessary to adjust the distance of each punching. This punching device requires manual operation, which reduces the efficiency of punching. Summary of the Invention

[0004] The purpose of the present invention is to provide an inner tube production and manufacturing equipment and a manufacturing process with a continuous punching function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions: Disclosed is an inner tube production and manufacturing device with a continuous punching function. The inner tube punching device comprises a conveying mechanism, a supporting mechanism, a rotating mechanism, a punching mechanism, a baffle mechanism, a pressing mechanism and a distance measuring mechanism. The conveying mechanism is provided with a baffle mechanism, which is located at the feeding end of the conveying mechanism. The conveying mechanism is provided with a distance measuring mechanism, which is located at one end of the conveying mechanism close to the baffle mechanism. The baffle mechanism and the distance measuring mechanism are respectively located on both sides of the conveying direction of the conveying mechanism. The pressing mechanism is provided with two groups, and the two groups of pressing mechanisms are respectively placed at both ends of the conveying mechanism. The supporting mechanism is placed on the ground, and the supporting mechanism is located on a side of the conveying mechanism where the baffle mechanism is provided. One side of the conveying mechanism is tightly connected to the supporting mechanism, the supporting mechanism is rotatably connected to the rotating mechanism, and the punching mechanism is slidably connected to the rotating mechanism.

[0006] The inner tube obtained by extrusion and cooling is transported by a conveyor belt into the area of ​​the punching equipment. The inner tube is moved to the appropriate position through the adjustment of the baffle mechanism. The inner tube is pressed by the pressing mechanism to change from a hollow tube to a flat two-layer rubber strip. The distance measuring mechanism measures the distance between the edge of the inner tube and the frame, and transmits the measured data to the rotating mechanism. The rotating mechanism adjusts the punching position of the punching mechanism to ensure that the punching mechanism can penetrate the two layers at the outermost edge of the inner tube. When the inner tube is transported to a position near the middle, the punching mechanism also rotates with the rotation of the rotating mechanism. When the punching mechanism rotates to the bottom, it is tangent to the inner tube and just cuts the two outermost layers of the inner tube. In the process of transporting the inner tube, the punching mechanism will continue to rotate with the rotating mechanism and punch holes in the inner tube. Since the rotation speed and the conveying speed remain unchanged, the relative distance of the inner tube is consistent each time.

[0007] Furthermore, the conveying mechanism includes a frame, an idler roller, a roller, a transmission gear, a first driving gear, a driving motor, a conveyor belt, a punching frame and a casing. The frame is located on the ground, the frame and the supporting mechanism are tightly connected, the frame and the casing are tightly connected, a driving motor is arranged in the casing, the output end of the driving motor is tightly connected to the first driving gear, the tooth surface of the first driving gear and the transmission gear are meshed, the transmission gear and the roller are tightly connected, the roller and the conveyor belt are in friction contact, the outer ring of the idler roller is provided with a roller, the idler roller and the roller are rotatably connected, the idler roller and the transmission gear are rotatably connected, the idler roller and the frame are tightly connected, the frame and the baffle mechanism are tightly connected, the frame and the pressing mechanism are tightly connected, the frame and the distance measuring mechanism are tightly connected, and a punching frame is provided on the frame, and the punching frame is located on the side of the frame where the distance measuring mechanism is provided.

[0008] The output torque of the driving motor drives the first driving gear to rotate, and the first driving gear drives the transmission gear to rotate through the engagement of the tooth surface. The transmission gear drives the roller to rotate through the fastening connection with the roller, and the roller drives the transmission of the conveyor belt through the friction contact with the conveyor belt. The roller is installed in the middle of the frame through the roller, and a total of six groups of rollers and transmission gears are set to drive the conveyor belt transmission. The baffle mechanism, the pressing mechanism and the distance measuring mechanism are installed on the upper surface of the frame. The baffle mechanism and the distance measuring mechanism are located at the feed end of the conveyor belt at the same time, and are respectively located on both sides of the conveyor belt. The pressing mechanism has two groups located at both ends of the frame, and a punching frame is installed on the side of the frame with the distance measuring mechanism.

[0009] Furthermore, a feed chute is provided on the punching frame, the opening of the feed chute is arranged upward, and the feed chute is arranged along the width direction of the conveyor belt.

[0010] A feed trough is provided in the middle of the punching frame, and the opening direction of the feed trough is upward. When the punching mechanism punches a hole in the inner tube, it is necessary to pierce the inner tube. At this time, the cutter head may pass through the inner tube and reach the bottom, and it is easy to exert a downward force on the inner tube, causing the inner tube to deform. Therefore, the two sides of the feed trough on the punching frame just support the bottom of the inner tube, leaving a position for punching, and protecting the punched inner tube to the greatest extent.

[0011] Furthermore, the supporting mechanism includes a base plate, a column, a first motor, a first lead screw, a lifting slider, a support shaft, a second drive gear and a gear motor. The base plate is located on the ground, the base plate and the column are tightly connected, the cross-sectional area of ​​the base plate is larger than the cross-sectional area of ​​the column, the side of the column close to the support shaft is tightly connected to the frame, the column and the first motor are tightly connected, the column and the lifting slider are slidingly connected, the column and the first lead screw are rotationally connected, the output end of the first motor and the first lead screw are tightly connected, the lifting slider is provided with a first thread groove, the first thread groove and the first lead screw are threadedly connected, the lifting slider and the support shaft are tightly connected, the support shaft and the rotating mechanism are rotationally connected, the lifting slider and the gear motor are tightly connected, the output end of the gear motor and the second drive gear are tightly connected, and the second drive gear is meshed with the rotating mechanism.

[0012] The baseplate rests on the ground, and the columns rest on it. The baseplate's large cross-section stabilizes the entire support mechanism. A first motor is fixed to the column. The first motor's output torque drives the first lead screw, which, through a threaded connection to the lift slider, converts torque into linear displacement, allowing the lift slider to move the rotation mechanism up and down. The gear motor's output torque drives the second drive gear, which, through meshing teeth, drives the rotation mechanism.

[0013] Furthermore, the rotating mechanism includes a rotating shaft, a second lead screw, a second motor, a first connecting frame, a rotating gear, a collar, a second connecting frame and a third connecting frame, the second driving gear and the rotating gear tooth surface are meshed, the supporting shaft and the rotating gear are rotatably connected, the rotating gear and the rotating shaft are tightly connected, the rotating shaft is provided with a rotating cavity, and notches are provided on both sides of the rotating cavity, the rotating shaft and the second motor are tightly connected, the second motor output end is tightly connected, the second lead screw and the rotating shaft are rotatably connected, the rotating shaft and the collar are slidingly connected, the collar is provided with a second threaded groove, the collar and the second lead screw are threadedly connected, the rotating shaft and the first connecting frame are tightly connected, the first connecting frame and the punching mechanism are hinged, the rotating shaft and the punching mechanism are slidably connected, the collar and the second connecting frame are tightly connected, the second connecting frame and the punching mechanism are hinged, the collar and the third connecting frame are tightly connected, and the third connecting frame and the punching mechanism are hinged.

[0014] The gear motor outputs torque to drive the second drive gear to rotate, and the second drive gear drives the rotating gear to rotate through tooth surface meshing. The rotating gear is tightly connected to the rotating shaft, driving the rotating shaft to rotate. The rotating shaft and the punching mechanism are slidingly connected, as well as the first connecting frame and the punching mechanism are hinged, the second connecting frame and the punching mechanism are hinged, and the third connecting frame and the punching mechanism are hinged. The punching mechanism rotates with the rotating shaft, and the collar is fixed on the rotating shaft through a sliding connection with the rotating shaft. The second motor outputs torque to drive the second lead screw to rotate. The second lead screw and the collar are threadedly connected to convert torque into linear displacement, and the collar can drive the punching mechanism to move laterally.

[0015] Furthermore, the punching mechanism includes a punching head, a base, a telescopic rod, a fourth connecting frame, a fifth connecting frame, a sixth connecting frame, a first rotating rod and a second rotating rod. The punching head and the base are fastened together, the output end of the telescopic rod is fastened together with the base, the other end of the telescopic rod is slidably connected to the rotating shaft, the base and the sixth connecting frame are fastened together, the sixth connecting frame is hinged to one end of the first rotating rod, the other end of the first rotating rod is hinged to the first connecting frame, the fourth connecting frame and the fifth connecting frame are respectively provided on one side of the base close to the column, the second rotating rod is provided with two groups, one end of the two groups of second rotating rods are respectively hinged to the fourth connecting frame and the fifth connecting frame, and the other end of the two groups of second rotating rods are respectively hinged to the second connecting frame and the third connecting frame.

[0016] By hingedly connecting one end of the two sets of second rotating rods to the fourth connecting frame and the fifth connecting frame respectively, and hingedly connecting the other ends to the second connecting frame and the third connecting frame respectively, the collar drives the two sets of second rotating rods to rotate when moving in the direction away from the column. At this time, the base will extend in the direction away from the rotating mechanism, and at the same time, the base drives the telescopic rod to extend, and the part of the telescopic rod sleeved on the outer side of the rotating shaft moves in the direction away from the column. In this way, the distance of the hole punched by the punching head is closer to the frame on the side with the distance measuring mechanism. Conversely, when the collar moves in the direction close to the column, the distance of the hole punched by the punching head is farther from the frame on the side with the distance measuring mechanism.

[0017] Furthermore, the baffle mechanism includes a baffle bracket and a special-shaped baffle, the baffle bracket is fastened to the frame, the baffle bracket is fastened to the special-shaped baffle, and the special-shaped baffle is provided with a guide slope and a guide plane in sequence along the conveying direction.

[0018] The baffle bracket is fastened to the special-shaped baffle, so that the baffle mechanism is stably placed on the frame. When the inner tube is transported into the punching device, the original position of the inner tube will be guided to the correct punching position through the guide slope and guide plane provided on the special-shaped baffle, ensuring the uniformity of the inner tube transportation position.

[0019] Furthermore, the pressing mechanism includes a pressure rod, a slide rail, a spring and a ring. The slide rail is tightly connected to the frame. Two sets of slide rails are provided on the frames on both sides of the conveyor belt. Pre-tightening grooves are provided on the two sets of slide rails. The upper end of the pre-tightening groove is tightly connected to one end of the spring, and the other end of the spring is tightly connected to the ring. The ring is rotatably connected to the pressure rod, and the pressure rod is slidably connected to the pre-tightening groove.

[0020] Two sets of slide rails are set on the frame to fix the position of the pressing mechanism. When the conveyor belt transports the inner tube, the pressing rod presses the tubular inner tube into a flat inner tube. At this time, the inner tube with a certain thickness will also lift the pressing rod to a certain height, causing the pressing rod to rise and compress the spring to a certain extent. At the same time, this state is maintained during the entire inner tube transportation process, which also plays a stabilizing role for the inner tube.

[0021] As shown in the figure, the distance measuring mechanism includes a mounting bracket and a distance meter. The mounting bracket is fastened to the frame, and the mounting bracket is fastened to the distance meter.

[0022] The rangefinder is stabilized on the frame by fastening the mounting bracket to the frame. After the inner tube is flattened, the side close to the rangefinder is at a certain distance from the frame. This distance is measured by the rangefinder, and the distance data is transmitted to the second motor, so that the second motor outputs torque to drive the collar to move back and forth, thereby controlling the distance between the punching head and the frame, so that the punching head can hit the outermost edge of the inner tube close to the rangefinder when rotating to punch.

[0023] Furthermore, the manufacturing process comprises the following steps: S1, loading through conveyor belt; S2, the inner tube is positioned on one side by guiding the special-shaped baffle, and the inner tube is flattened by two pressing mechanisms; S3, detecting the width of the inner tube by a distance measuring mechanism, and adjusting the position of the punching cutter head according to the width of the inner tube so that the axis of the punching cutter head and the edge line of the inner tube are located on the same plane; S4. Expand the punched inner tube to form the valve hole.

[0024] The inner tube is conveyed into the device via a conveyor belt, the position of the inner tube close to the side of the special-shaped baffle is determined by the special-shaped baffle, and then the inner tube is pressed from a ring shape into a flat two-layer structure by a pressing mechanism, the distance between one side of the inner tube and the frame is measured by a distance measuring mechanism, and the position of the punching head driven by the ring is moved to the side of the inner tube so that the axis of the punching head and the edge line of the inner tube are on the same plane, and the second drive gear is driven to rotate the rotating mechanism and the punching mechanism so that the punching head cuts the inner tube to punch a hole, and the punched inner tube is unfolded to form a valve, and then the inner tube is conveyed to the next device via a conveyor belt.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: when the inner tube is conveyed by the conveyor belt, the position of the punching is first determined by the baffle mechanism, and then it is pressed into a flat shape by the pressing mechanism, and then the distance between the edge of the inner tube and the frame is measured by the distance measuring mechanism, and the data is transmitted to the second motor. The movement of the collar is controlled by the output torque to determine the distance between the punching head and the frame, so that the punching head can hit the inner tube near the edge when it rotates to punch, and directly penetrate two layers. In this way, when punching, there is no need to worry about whether only punching through one layer of inner tube will affect the other layer of inner tube. At the same time, when punching holes in inner tubes of different batches, it is only necessary to measure the distance from the side of the inner tube to the frame by the distance measuring mechanism, and the punching head can be adjusted to the corresponding position for punching, without the need to replace the punching equipment.

[0031] The inner tube obtained by extrusion and cooling is transported by the conveyor belt 17 into the area of ​​the punching equipment. The inner tube is moved to the appropriate position by the adjustment of the baffle mechanism 5. The inner tube is pressed by the pressing mechanism 6 and changed from a hollow tube to a flat two-layer rubber strip. The distance measuring mechanism 7 measures the distance between the edge of the inner tube and the frame 11, and transmits the measured data to the rotating mechanism 3. The rotating mechanism 3 adjusts the punching position of the punching mechanism 4 to ensure that the punching mechanism 4 can penetrate the two layers at the outermost edge of the inner tube. When the inner tube is transported to a position near the middle, the punching mechanism 4 also rotates with the rotation of the rotating mechanism 3. When the punching mechanism 4 rotates to the bottom, it is tangent to the inner tube and just cuts the two outermost layers of the inner tube. In the process of transporting the inner tube, the punching mechanism 4 will continue to rotate with the rotating mechanism 3 and punch the inner tube. Since the rotation speed and the conveying speed remain unchanged, the relative distance of the inner tube is consistent each time.

[0032] like Figure 1-Figure 2As shown, the conveying mechanism 1 includes a frame 11, a roller 12, a roller 13, a transmission gear 14, a first drive gear 15, a drive motor 16, a conveyor belt 17, a punching frame 18 and a casing 19.

[0033] The output torque of the driving motor 16 drives the first driving gear 15 to rotate, and the first driving gear 15 drives the transmission gear 14 to rotate through the engagement of the tooth surface. The transmission gear 14 drives the roller 13 to rotate through the fastening connection with the roller 13. The roller 13 drives the transmission of the conveyor belt 17 through friction contact with the conveyor belt 17. The roller 13 is installed in the middle of the frame 11 through the roller 12, and a total of six groups of rollers 13 and transmission gears 14 are provided to drive the transmission of the conveyor belt 17. The baffle mechanism 5, the pressing mechanism 6 and the distance measuring mechanism 7 are installed on the upper surface of the frame 11.

The pressing mechanism 6 has two groups located at both ends of the frame 11. At the same time, a punching frame 18 is installed on the side of the frame 11 with the distance measuring mechanism 7.

[0035] A feed trough 181 is provided in the middle of the punching frame 18, and the opening direction of the feed trough 181 is upward. When the punching mechanism 4 punches a hole in the inner tube, it is necessary to pierce the inner tube. At this time, the cutter head may pass through the inner tube and reach the bottom, and it is easy to apply a downward force to the inner tube, causing the inner tube to deform. Therefore, the two sides of the feed trough 181 on the punching frame 18 just support the bottom of the inner tube, leaving a position for punching, thereby protecting the punched inner tube to the greatest extent.

[0039] The gear motor 28 outputs torque to drive the second drive gear 27 to rotate, and the second drive gear 27 drives the rotating gear 35 to rotate through tooth surface meshing. The rotating gear 35 is tightly connected to the rotating shaft 31 to drive the rotating shaft 31 to rotate. Through the sliding connection between the rotating shaft 31 and the punching mechanism 4, as well as the hinge of the first connecting frame 34 and the punching mechanism 4, the hinge of the second connecting frame 37 and the punching mechanism 4, and the hinge of the third connecting frame 38 and the punching mechanism 4, the punching mechanism 4 rotates with the rotating shaft 31. The ring 36 is connected to the rotating shaft 31 through sliding connection. The second motor 33 is fixed on the rotating shaft 31. The second motor 33 outputs torque to drive the second lead screw 32 to rotate. The second lead screw 32 and the ring 36 are threadedly connected to convert torque into linear displacement. The ring 36 can drive the punching mechanism 4 to move laterally.

[0040] like Figure 5 As shown, the punching mechanism 4 includes a punching head 41, a base 42, a telescopic rod 43, a fourth connecting frame 44, a fifth connecting frame 45, a sixth connecting frame 46, a first rotating rod 47 and a second rotating rod 48. The punching head 41 is tightly connected to the base 42, the output end of the telescopic rod 43 is tightly connected to the base 42, the other end of the telescopic rod 43 is slidingly connected to the rotating shaft 31, the base 42 is tightly connected to the sixth connecting frame 46, the sixth connecting frame 46 is hinged to one end of the first rotating rod 47, and the other end of the first rotating rod 47 is hinged to the first connecting frame 34. The base 42 is provided with a fourth connecting frame 44 and a fifth connecting frame 45 on one side close to the column 22, and the second rotating rod 48 is provided with two groups.

[0041] By hingedly connecting one end of the two groups of second rotating rods 48 to the fourth connecting frame 44 and the fifth connecting frame 45 respectively, and hingedly connecting the other ends to the second connecting frame 37 and the third connecting frame 38 respectively, the collar 36 drives the two groups of second rotating rods 48 to rotate when it moves in the direction away from the column 22. At this time, the base 42 will extend in the direction away from the rotating mechanism 3. At the same time, the base 42 drives the telescopic rod 43 to extend, and the part of the telescopic rod 43 that is sleeved on the outside of the rotating shaft 31 moves in the direction away from the column 22. In this way, the distance of the hole made by the punching head 41 is closer to the frame 11 on the side with the distance measuring mechanism 7. Conversely, when the collar 36 moves in the direction close to the column 22, the distance of the hole made by the punching head 41 is farther from the frame 11 on the side with the distance measuring mechanism 7.

[0042] like Figure 1 As shown, the baffle mechanism 5 includes a baffle bracket 51 and a special-shaped baffle 52. The baffle bracket 51 is fastened to the frame 11, and the baffle bracket 51 is fastened to the special-shaped baffle 52. The special-shaped baffle 52 is provided with a guide slope and a guide plane in sequence along the conveying direction.

[0043] The baffle bracket 51 is fastened to the special-shaped baffle 52, so that the baffle mechanism 5 is stably placed on the frame 11. When the inner tube is transported into the punching device, the original position of the inner tube will be guided to the correct punching position through the guide slope and guide plane provided on the special-shaped baffle 52, thereby ensuring the uniformity of the inner tube transportation position.

[0044] like Figure 3 As shown, the pressing mechanism 6 includes a pressure rod 61, a slide rail 62, a spring 63 and a ring 64. The slide rail 62 is tightly connected to the frame 11. Two groups of slide rails 62 are provided on the frame 11 on both sides of the conveyor belt 17. The two groups of slide rails 62 are provided with pre-tightening grooves 621. The upper end of the pre-tightening groove 621 is tightly connected to one end of the spring 63, and the other end of the spring 63 is tightly connected to the ring 64. The ring 64 is rotatably connected to the pressure rod 61, and the pressure rod 61 is slidably connected to the pre-tightening groove 621.

[0045] Two sets of slide rails 62 are set on the frame 11 to fix the position of the pressing mechanism 6. When the conveyor belt 17 transports the inner tube, the pressing rod 61 presses the tubular inner tube into a flat inner tube. At this time, the inner tube with a certain thickness will also lift the pressing rod 61 to a certain height, causing the pressing rod 61 to rise and compress the spring 63 to a certain extent. At the same time, the state at this time is maintained during the entire inner tube transportation process, which also plays a stabilizing role for the inner tube.

[0046] like Figure 6 As shown, the distance measuring mechanism 7 includes a mounting bracket 71 and a distance meter 72 . The mounting bracket 71 is fastened to the frame 11 , and the mounting bracket 71 is fastened to the distance meter 72 .

[0047] By fastening the mounting bracket 71 to the frame 11, the rangefinder 72 is stabilized on the frame 11. After the inner tube is flattened, the side close to the rangefinder 72 is at a certain distance from the frame 11. At this time, this distance is obtained by measuring the rangefinder 72, and the distance data is transmitted to the second motor 33, so that the second motor 33 outputs torque to drive the collar 36 to move back and forth, thereby controlling the distance between the punching head 41 and the frame 11, so that the punching head 41 can hit the outermost position of the inner tube close to the rangefinder 72 when rotating to punch.

[0048] like Figure 1 As shown, the manufacturing process includes the following steps: S1, loading through conveyor belt 17; S2, the inner tube is positioned on one side by guiding the special-shaped baffle 52, and the inner tube is flattened by two pressing mechanisms 6; S3, detecting the width of the inner tube by the distance measuring mechanism 7, and adjusting the position of the punching head 41 according to the width of the inner tube so that the axis of the punching head 41 and the edge line of the inner tube are on the same plane; S4. Expand the punched inner tube to form the valve hole.

[0049] The inner tube is conveyed into the device by the conveyor belt 17, the position of the inner tube close to the side of the special-shaped baffle 52 is determined by the special-shaped baffle 52, and then the inner tube is pressed from a ring shape into a flat two-layer structure by the pressing mechanism 6. The distance between one side of the inner tube and the frame 11 is measured by the distance measuring mechanism 7, and the ring 36 is adjusted to drive the punching head 41 to move to the position of the side of the inner tube so that the axis of the punching head 41 is on the same plane as the edge line of the inner tube. The second drive gear 27 is driven to rotate the rotating mechanism 3 and the punching mechanism 4, so that the punching head 41 cuts into the inner tube to punch a hole, and the punched inner tube is unfolded to form a valve, and then the inner tube is conveyed to the next device by the conveyor belt 17.

[0050] Working principle of the present invention: When the inner tube is conveyed by the conveyor belt 17, the position of the punching is first determined by the baffle mechanism 5, and then it is pressed into a flat shape by the pressing mechanism 6. Then, the distance between the edge of the inner tube and the frame 11 is measured by the distance measuring mechanism 7, and the data is transmitted to the second motor 33. The movement of the output torque control ring 36 is used to determine the distance between the punching head 41 and the frame 11, so that the punching head 41 can hit the inner tube near the edge when rotating to punch, and directly penetrate two layers. In this way, when punching, there is no need to worry about whether only punching through one layer of inner tube will affect the other layer of inner tube. At the same time, when punching holes in inner tubes of different batches, it is only necessary to measure the distance from the side of the inner tube to the frame 11 by the distance measuring mechanism 7, and the punching head 41 can be adjusted to the corresponding position for punching, without the need to replace the punching equipment.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
