[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] As attached Figures 1 to 10The present invention provides a feeding and taking device 1 for a fixed-length flexible sound suppressing member (such as a mute sponge, etc., which is described below by taking the mute sponge as an example), which comprises a bracket 10 and a feeding device 20 arranged on the bracket 10, wherein the feeding device 20 comprises a feeding device 21, and the feeding device 21 can be fed in multiple directions (such as along the side) Figure 1 and a feeding device 30 disposed on the bracket 10, wherein the feeding device 30 is provided with a material trough 31 and a material driving device 32; and a reversible material receiving device 40 disposed on one side of the material trough 31.

[0030] Through the above configuration structure of the present invention, the silent sponge 100 that has been pre-cut into a predetermined length and placed in the material cart 200 can be grabbed by the material picker 21 and conveyed to the material receiving device 40, and the silent sponge 100 can be vertically conveyed to the material trough 31 after being turned over by the material receiving device 40, and then driven by the material driving device 32 to flow along the predetermined conveying channel in the material trough 31 to the next process (i.e., conveyed to the laminating device 2). The present invention can realize the operation mode of automatically grabbing and conveying the silent sponge of fixed length, and has the advantages of simple structure, low cost, and no manual operation.

[0031] In addition, the bracket 10 described in the present invention can be divided into a first bracket 101 (similar to a door-type bracket) and a second bracket 102, and the material picking device 20 is arranged on the first bracket 101, and the material cart 200 on which the segmented silent sponge 100 is placed is movably arranged under the first bracket 101; the feeding device 30 is arranged on the second bracket 102, so as to facilitate the disassembly and assembly of the feeding device and subsequent maintenance.

[0032] The material taking device 20 of the present invention comprises a device that drives the material taking device 21 along the adjacent Figure 1 The first driving device 22 reciprocates in the first direction X shown in FIG. 1 , and drives the material picker 21 to move along the adjacent Figure 1 The second driving device 23 reciprocates in the second direction Y shown in FIG. Preferably, the first driving device 22 of the present invention comprises a first driver 221, a first transmission mechanism 222 and a plurality of first connecting members 223, wherein the driving end of the first driver 221 is connected to one end (such as a synchronous pulley) of the first transmission mechanism 222 (such as a synchronous belt); the other end of the first transmission mechanism 222 and the first driver 221 are fixedly arranged on the first bracket 101 through the first connecting member 223.

[0033] In addition, the second driving device 23 of the present invention includes a second driver 231, a second transmission mechanism 232 and a second connecting member 233, the driving end (such as a gear) of the second driver 231 is connected to the second transmission mechanism 232 (including a rack) by a gear-to-rack meshing mode, one end of the second transmission mechanism 232 is connected to the material picker 21, the second driver 231 is fixedly arranged on the second connecting member 233, the second transmission mechanism 232 can reciprocate up and down in the Y-axis direction relative to the second connecting member 233 under the drive of the second driver 231, the second driver 231 and the second transmission mechanism 232 are fixedly arranged on the second connecting member 233 and connected to the first transmission mechanism 222 through the second connecting member 233, so that the second driving device 23 can reciprocate along the X-axis direction of the first bracket 101 as a whole. Therefore, the present invention realizes the up and down and left and right movement of the material picker 21 through the above-mentioned first driving device 22 and the second driving device 23, thereby realizing the function of grabbing and conveying the silent sponge.

[0034] Furthermore, the material picker 21 of the present invention includes a mounting seat 211, and a plurality of gripping elements 212 and a first detection element 213 disposed on the mounting seat 211. Specifically, the gripping element 212 of the present invention may include a connecting plate 2121, a needle suction cup 2122, a second detection element 2123 (such as a photoelectric proximity switch) and a movable component 2124. The needle suction cup 2122 is disposed on one side of the connecting plate 2121, the second detection element 2123 and the movable component 2124 are disposed on the other side of the connecting plate 2121, and the movable component 2124 is used to trigger the second detection element 2123 to work.

[0035] To achieve the function of the movable component 2124 triggering the second detection element 2123 to work. The movable component 2124 of the present invention may include a linear bearing 2124A, the linear bearing 2124A is fixedly connected to one end of the connecting plate 2121, and a guide rod 2124B that can move up and down and a spring 2124C arranged on the peripheral side of the guide rod are arranged in the linear bearing 2124A, and a contact end T2 is arranged on the lower side of the guide rod 2124B, and a free end T1 is arranged on the upper side of the guide rod 2124B. Generally, the bottom surface of the contact end T2 protrudes and is arranged on the bottom surface of the needle suction cup 2122. Therefore, when the grasping element 212 moves to the surface of the pre-cut long strip of silent sponge and then continues to move downward, the contact end T2 is subjected to force to compress the spring 2124C, so that the spring 2124C drives the free end T1 to move upward to the photoelectric proximity switch 2123 and triggers its operation. Since the contact end T2 and the bottom surface of the needle suction cup 2122 are fully in contact with the silent sponge at this time, after the photoelectric proximity switch 2123 is triggered, the plurality of needle suction cups 2122 begin to grasp the silent sponge. Through the above configuration, the picker 21 can accurately grasp the silent sponge.

[0036] It should be noted that the first detection element 213 can be a ranging element such as a 3D camera or an infrared ranging sensor, which is used to detect whether there is a silent sponge at its current corresponding position, and to measure the distance between the first detection element 213 and the silent sponge, so as to enable the material picker 21 to automatically grab and load the silent sponge 100 in the material cart 200, thereby realizing fully automated operation of silent sponge picking and feeding without manual operation.

[0037] In addition, the material trough 31 of the present invention includes a first side plate 311 and a second side plate 312, and the first side plate 311 is arranged higher than the second side plate 312, and a plurality of stop rollers G are arranged at the first side plate 311 and the second side plate 312. The material driving device 32 includes a material driver 321, a plurality of first rollers 322 and second rollers 323, and a linkage structure 324 (such as a synchronous belt and synchronous pulley structure). The material driver 321 drives the first roller 322 and the second roller 323 to rotate through the linkage structure 324 to move the vertically placed silent sponge 100 clamped between the first side plate 311 and the second side plate 312 forward in the material trough 31, thereby realizing the transportation of the silent sponge. Specifically, as shown in the attached Figure 8 and 9As shown, the linkage structure 324 includes a synchronous pulley 3241 and a synchronous belt 3242. The synchronous pulley 3241 rotates coaxially with the first roller 322. The material driver 321 provides power to make the synchronous pulley 3241 and the synchronous belt 3242 rotate synchronously. The second roller 323 is linked with the gear set 326 via the second synchronous belt 325 assembly, so that the first roller 322 and the second roller 323 rotate in opposite directions, that is, a rotational force in the same direction is applied to the vertically placed silent sponge 100 clamped between the first side plate 311 and the second side plate 312, thereby driving the silent sponge to move forward.

[0038] In addition, the present invention is provided with a material detection sensor (not shown) on the material trough 31, which is used to detect whether a silent sponge 100 is conveyed into the material trough 31. Preferably, the material driving device 32 of the present invention further includes a guide rod 327, a first slider 3231 and an adjusting cylinder 328, and the retractable driving end 3281 of the adjusting cylinder 328 is connected to the first slider 3231, and the first slider 3231 and the second roller 323 can move synchronously along the guide rod 327. Therefore, when a silent sponge 100 is conveyed into the material trough 31, the retractable driving end of the adjusting cylinder 328 drives the first slider 3231 to move toward the first roller 322, that is, drives the second roller 323 to move toward the first roller 322 to clamp the silent sponge 100, so when the material driver 321 is driven, the first roller 322 and the second roller 323 rotate, which can increase the friction between the silent sponge and the first roller 322 and the second roller 323, and drive the silent sponge to move forward. Through the above configuration, the present invention can realize the functions of automatically detecting materials and driving the movement of materials.

[0039] Furthermore, the material driving device of the present invention further comprises a second slider 329, a screw rod 3291 and a hand wheel 3292. The second slider 329 moves along the guide rod 327 in the same manner as the first slider 3231. The adjusting cylinder 328 is arranged on the second slider 329. The hand wheel 3292 is connected to the second slider 329 via the screw rod 3291. When the distance between the first roller 322 and the second roller 323 needs to be manually adjusted, the hand wheel 3292 can be manually rotated to drive the screw rod 3291 to move and then push the second slider 329 to move toward the first slider 3231, that is, push the adjusting cylinder 328 arranged on the second slider 329 to move toward the first slider 3231, so as to drive the first slider 3231 to move toward the first roller 322, and the function of increasing the friction between the mute sponge and the first roller 322 and the second roller 323 can also be realized.

[0040] The material receiving device 40 of the present invention comprises a material receiving plate 41, a rotating fixed part 42 and a flip driver 43. The rotating fixed part 42 may be provided in plurality, and one end of the rotating fixed part 42 is connected to the material trough 31, and the other end of the rotating fixed part 42 is connected to the material receiving plate 41; one end of the flip driver 43 is connected to the second bracket 102, and the other end of the flip driver 43 is connected to the material receiving plate 41. When the material taker 21 takes out the silent sponge 100 and conveys it to the material receiving plate 41, the flip driver 43 drives the material receiving plate 41 to flip toward the material trough 31 side, so as to convey the silent sponge 100 vertically into the material trough 31, and then drives the silent sponge 100 to move to the next process through the material driver 321.

[0041] Through the above-mentioned configuration structure, the present invention can transport the silent sponge 100 pre-cut into a predetermined length and placed approximately horizontally in the material cart 200 through the material picker 21 to the approximately horizontal material receiving plate 41, and then drive the driver 43 to flip the material receiving plate 41 toward the material trough 31, and transport the silent sponge 100 vertically into the material trough 31, thereby realizing the silent sponge 100 being transported to the bonding device 2 in an approximately vertical manner.

[0042] Therefore, the present invention can also provide a laminating system for manufacturing a flexible sound suppressor for a silent tire, the laminating system comprising a feeding device 1 and a laminating device 2 for a fixed length of a flexible sound suppressor (the specific structure and working principle of the laminating device are detailed in the invention patent content No. 2021107198672 of the applicant), the laminating device 2 receives the silent sponge 100 provided by the feeding device 1 in a vertical manner, and applies the silent sponge 100 to the inner surface of the tire 300 through the laminating device 2. It should be noted that the above-mentioned drivers of the present invention can be servo motors or cylinders, etc.
