Description

Technical Field

[0001] This invention relates to the field of tire production equipment technology, and more specifically, to an automatic feeding device. Background Art

[0002] During tire forming, once the inner liner is empty, the machine needs to be stopped. An empty trolley is manually pushed out, and a trolley filled with inner liner is pushed in, with the beginning and end of the liner material overlapped. Because the entire process requires manual labor, the downtime is long, the level of automation is low, and tire production efficiency is affected.

[0003] In the prior art, to solve the above problems, there is an automatic feeding device for inner lining layers. This device requires the material head to be placed in a fixed position, the material tail to be placed on the material head by a suction cup, and then sewing with a sewing roller to achieve automatic feeding. However, this device requires the material head to be placed in a fixed position before feeding, which places high demands on tire manufacturers and is not conducive to widespread use.

[0041] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] To address the problem of poor performance in existing automatic feeding devices, this invention provides an automatic feeding device.

[0043] like Figures 1 to 8 As shown, the automatic feeding device includes a feeding module 10, a lifting module 20, a feeding module 30, and a sewing module 40. The feeding module 10 is used to supply adhesive material and has a feeding end. The lifting module 20 is disposed on the side of the feeding module 10 near the feeding end. The feeding module 30 is disposed on the lifting module 20 and can move with the lifting module 20. At least a portion of the feeding module 30 can move relative to the lifting module 20 in a direction close to or away from the feeding module 10, and at least another portion of the feeding module 30 can move in a direction perpendicular to the conveying direction of the feeding module 30. The sewing module 40 is disposed on the side of the feeding module 30 away from the lifting module 20. At least a portion of the sewing module 40 can move in a direction close to or away from the feeding module 30 and can overlap the head and tail of two adjacent adhesive materials located on the feeding module 30.

[0044] In this solution, the feeding module 30 is lifted and moved to a specific position by the lifting module 20, so that one end of the feeding module 30 is located below the feeding end of the feeding module 10, facilitating the reception of the head of the adhesive material from the feeding module 10. At least a portion of the feeding module 30 can move relative to the lifting module 20 in a direction close to the feeding module 10 to move the tail of the material to the overlapping position. At least another portion of the feeding module 30 can move in a direction perpendicular to the conveying direction of the feeding module 30, i.e., along the width direction of the adhesive material, to align the edges of the head and tail of the material in the width direction. At least a portion of the sewing module 40 can move in a direction close to the feeding module 30 to overlap the head of one adhesive material and the tail of another adhesive material located on the feeding module 30. The head and tail of the material overlap under the action of the sewing module 40. The head of the material does not need to be placed in a fixed position before feeding, which can achieve the purpose of automatic feeding. The automatic feeding device has better performance, saves production costs, and is conducive to widespread use.

[0045] It should be noted that, in this embodiment, the conveying direction of the feeding module 30 is the length direction of the adhesive material, and the direction perpendicular to the conveying direction of the feeding module 30 is the width direction of the adhesive material.

[0046] It should be noted that in this embodiment, the feeding module 10 is a full-load trolley. The feeding module 10 includes a stripping roller 11 and a material head 12. The material head 12 of the material roll extends out of the feeding module 10 through the stripping roller 11.

[0047] It should be noted that, in this embodiment, the lifting module 20 includes a power assembly 21, a drive shaft 22, a first bevel gear 23, a second bevel gear 24, a lead screw 25, a lead screw nut 26, and a lifting frame 27. The power assembly 21 is driven and connected to the drive shaft 22, causing the drive shaft 22 to rotate. A first bevel gear 23 is provided at each end of the drive shaft 22. Two lead screws 25 are symmetrically arranged at both ends of the drive shaft 22. Each lead screw 25 has a second bevel gear 24, which meshes with the first bevel gear 23. The lead screw nut 26 is sleeved on the lead screw 25 and can move up and down along the lead screw 25. The lead screw nut 26 is connected to the lifting frame 27. Thus, the power assembly 21 sequentially drives the drive shaft 22 and the lead screw 25 to rotate, and through the lead screw nut 26, drives the lifting frame 27 to move up and down. The lifting frame 27 is connected to the base 313 of the feeding module 30.

[0048] like Figure 1 , Figure 3 and Figure 8As shown, the feeding module 30 includes a feeding assembly 31 and a conveying assembly 32. The feeding assembly 31 is movably mounted on the lifting module 20 and moves with the lifting module 20, and at least a portion of the feeding assembly 31 can move in a direction close to or away from the feeding module 10. The conveying assembly 32 is movably mounted on the feeding assembly 31, located downstream of the feeding module 10 and upstream of the feeding assembly 31, and at least a portion of the conveying assembly 32 can move in a direction perpendicular to the conveying direction of the feeding module 30. Thus, the lifting module 20 drives the feeding module 30 upward to facilitate feeding of the material head and tail, and they descend together to avoid the storage bag. At least a portion of the feeding assembly 31 moves in a direction close to the feeding module 10 to move the material tail to the overlapping position. The conveying assembly 32 is used to receive and convey the material head 12 of the adhesive material, and the conveying assembly 32 can drive the material head 12 to move along the width direction of the adhesive material to align the material head 12 with the material tail, ensuring that the overlapping position of the material head and tail meets quality requirements.

[0049] like Figures 3 to 5 As shown, the feeding module 30 also includes a correction component 33. At least a portion of the correction component 33 is movably mounted on the unloading component 31. The correction component 33 is drivenly connected to the conveying component 32 and can drive at least a portion of the conveying component 32 to move in a direction perpendicular to the conveying direction of the feeding module 30. The correction component 33 is located on the side of the conveying component 32 away from the sewing module 40. In this way, the correction component 33 is located on the side of the conveying component 32 away from the adhesive material to prevent interference between the correction component 33 and the adhesive material. The correction component 33 drives the conveying component 32 to move along the width direction of the adhesive material to achieve the correction purpose.

[0050] like Figures 3 to 5 As shown, the correction assembly 33 includes a first mounting frame 331 and a first drive unit 332. At least a portion of the first mounting frame 331 is movably mounted on the unloading assembly 31, and one end of the conveying assembly 32 near the unloading assembly 31 is mounted on the first mounting frame 331 and moves with the first mounting frame 331. The first drive unit 332 is drivenly connected to the first mounting frame 331 and drives the first mounting frame 331 to move in a direction perpendicular to the conveying direction of the feeding module 30. In this way, the first drive unit 332 drives the first mounting frame 331 to move, thereby driving the conveying assembly 32 to move, achieving the correction purpose of the material head 12.

[0051] It should be noted that in this embodiment, the first mounting frame 331 is provided with a plurality of second sliders 3311, and the second mounting frame 314 is provided with a plurality of slide rails. The plurality of second sliders 3311 correspond one-to-one with the plurality of slide rails and slide in cooperation, so that the first mounting frame 331 can move in a direction perpendicular to the conveying direction of the feeding module 30.

[0052] It should be noted that, in this embodiment, the correction assembly 33 further includes a first lead screw 333 and a lead screw nut 334. The first drive unit 332 is drivenly connected to the first lead screw 333 and can drive the first lead screw 333 to rotate. The lead screw nut 334 is sleeved on the first lead screw 333 and is connected to the first mounting bracket 331, so that the lead screw nut 334 can drive the first mounting bracket 331 to move along the first lead screw 333, so as to adjust the position of the material head 12 to achieve the purpose of correction.

[0053] like Figure 1 and Figure 7 As shown, the automatic feeding device also includes a first detection component 50 and at least two first sensing components 60. The first detection component 50 is disposed on the side of the sewing module 40 near the conveying component 32 and is signal-connected to the first driving unit 332. The two first sensing components 60 cooperate with the first detection component 50, and at least one first sensing component 60 is disposed at the end of the conveying component 32 and the unloading component 31 that are close to each other. In this way, the first detection component 50 detects the material tail edge position located on the unloading component 31 and the material head 12 edge position located on the conveying component 32. If there is a deviation between the material tail edge position and the material head 12 edge position, the first driving unit 332 is controlled to drive the conveying component 32 to move along the width direction of the adhesive material to ensure that the material head 12 and the material tail are aligned.

[0054] like Figure 3 As shown, a first sensing component 60 is respectively provided at one end of the conveying component 32 and the unloading component 31, close to each other. The two first sensing components 60 are arranged opposite each other, and are respectively located at one end of the conveying component 32 and the unloading component 31 in the width direction. In this way, the first sensing component 60 located on the conveying component 32 is used to detect the position of one side of the material head 12 in the width direction, and the first sensing component 60 located on the unloading component 31 is used to detect the position of the corresponding side of the material tail in the width direction, so as to improve the detection efficiency.

[0055] like Figure 3As shown, the first sensing component 60 includes a first reflector 61, and the first detection component 50 includes a first control unit, a first photocell 51, a second photocell 52, and a second drive unit 53. The first control unit is signal-connected to the first drive unit 332. The first photocell 51 is disposed corresponding to the first reflector 61 on the conveying component 32 and is capable of receiving the light signal reflected by the first reflector 61 on the conveying component 32. The second photocell 52 is disposed corresponding to the first reflector 61 on the unloading component 31 and is capable of receiving the light signal reflected by the first reflector 61 on the unloading component 31. The first photocell 51 and the second photocell 52 are respectively signal-connected to the first control unit. The second drive unit 53 is drive-connected to the first photocell 51 and the second photocell 52 respectively, and drives the first photocell 51 and the second photocell 52 to move in a direction perpendicular to the conveying direction of the feeding module 30. Thus, the first photocell 51 corresponds to the first reflector 61 on the conveying assembly 32 and is used to detect the side position of the material head 12. The second photocell 52 corresponds to the first reflector 61 on the unloading assembly 31 and is used to detect the side position of the material tail. When there is a deviation between the side position of the material head 12 and the side position of the material tail, the first control unit controls the first drive unit 332 to move to correct the deviation. When a different specification of rubber material is changed, the width of the rubber material changes. The second drive unit 53 drives the first photocell 51 and the second photocell 52 to move in a direction perpendicular to the conveying direction of the feeding module 30, so as to ensure that the signals emitted by the first photocell 51 and the second photocell 52 can illuminate the edge position in the width direction of the rubber material, so as to accurately detect the edge position of the material head 12 and the edge position of the material tail.

[0056] It should be noted that in this embodiment, the first detection component 50 further includes a photoelectric sensor mounting base 54, a third slider 55, a second lead screw 56, and a connecting base 57. The second drive unit 53 and the second lead screw 56 are respectively disposed on the connecting base 57. The second drive unit 53 is drivenly connected to the second lead screw 56 and can drive the second lead screw 56 to rotate. The photoelectric sensor mounting base 54 is sleeved on the second lead screw 56 and can move along the second lead screw 56. The first photoelectric sensor 51 and the second photoelectric sensor 52 are respectively disposed on the photoelectric sensor mounting base 54. The photoelectric sensor mounting base 54 drives the first photoelectric sensor 51 and the second photoelectric sensor 52 to move in a direction perpendicular to the conveying direction of the feeding module 30. In this way, when a different type of adhesive is changed, the width of the adhesive changes, and the positions of the first photoelectric sensor 51 and the second photoelectric sensor 52 are adjusted to ensure that the signals emitted by the first photoelectric sensor 51 and the second photoelectric sensor 52 can cover the side positions of the adhesive in the width direction.

[0057] It should be noted that, in this embodiment, the area of ​​the square signal emitted by the first photoelectric sensor 51 is smaller than the area of ​​the directional region of the first reflector 61 of the transmission component 32, and the area of ​​the square signal emitted by the second photoelectric sensor 52 is smaller than the area of ​​the directional region of the first reflector 61 of the unloading component 31.

[0058] like Figure 3 As shown, the conveying assembly 32 has a first conveying section 321, and the unloading assembly 31 has a second conveying section 311. At least a portion of the head 12 of one of the two overlapping adhesive materials is located on the first conveying section 321, and at least a portion of the tail of the other adhesive material is located on the second conveying section 311. The unloading assembly 31 also has an overlapping portion 312, which is disposed between the first conveying section 321 and the second conveying section 311. The sewing module 40 is located above the overlapping portion 312 and can move towards or away from the overlapping portion 312. Thus, the sewing module 40 overlaps the head 12 of the first conveying section 321 with the tail of the second conveying section 311 at the overlapping portion 312.

[0059] like Figure 3 As shown, the first conveying section 321 and the second conveying section 311 have the same height, and the height of the overlapping portion 312 is less than the height of the first conveying section 321. Thus, the rubber material passes sequentially through the first conveying section 321 and the second conveying section 311. The equal height of the first and second conveying sections 321 and 311 facilitates the conveying of the rubber material. The height of the overlapping portion 312 is less than the height of the first conveying section 321. When the unloading assembly 31 moves towards the conveying assembly 32, the overlapping portion 312 avoids the second conveying section 311 moving towards the first conveying section 321. At this time, the second conveying section 311 is partially located above the overlapping portion 312, and the material head 12 and the material tail overlap on the portion of the second conveying section 311 located above the overlapping portion 312.

[0060] like Figure 5 As shown, the conveying assembly 32 includes a third drive unit 322, a drive roller 323, a driven roller 324, and synchronous belts 325. The third drive unit 322 is driven and connected to the drive roller 323, driving the drive roller 323 to rotate. The axial direction of the drive roller 323 is perpendicular to the conveying direction of the feeding module 30. Multiple synchronous belts 325 are respectively fitted onto the drive roller 323 and the driven roller 324. The multiple synchronous belts 325 are parallel and spaced apart, forming a first conveying section 321. Thus, the third drive unit 322 drives the drive roller 323 to rotate, and the drive roller 323 drives the multiple synchronous belts 325 and the driven roller 324 to move, ensuring that the material head 12 can move towards the material tail direction through the first conveying section 321.

[0061] It should be noted that, in this embodiment, the conveying assembly 32 further includes a transition plate 326, a transmission belt 327, a transmission pulley 328, and a synchronous pulley 329. The third drive unit 322 is driven by the transmission belt 327, causing it to move. The transmission belt 327 is connected to the transmission pulley 328, causing it to rotate. The transmission pulley 328 is mounted on the drive roller 323, causing it to rotate. Multiple synchronous pulleys 329 are also mounted on the drive roller 323. The rotation of the drive roller 323 causes the multiple synchronous pulleys 329 to rotate synchronously. A synchronous belt 325 is mounted on the multiple synchronous pulleys 329 and the driven roller 324, respectively. The rotation of the synchronous pulleys 329 causes the synchronous belt 325 to move, thereby realizing the movement of the first conveying section 321 toward the unloading assembly 31. The transition plate 326 is located between the synchronous belt 325 and the unloading plate 317, and a first reflector 61 is mounted on the transition plate 326.

[0062] like Figure 3 and Figure 4 As shown, the unloading assembly 31 includes a base 313, a second mounting bracket 314, a fourth drive unit 315, a fifth drive unit 316, and an unloading plate 317. The second mounting bracket 314 is disposed on the base 313 and has an overlapping portion 312. The conveying assembly 32 is disposed on the second mounting bracket 314. The fourth drive unit 315 is disposed on the base 313 and is drivenly connected to the second mounting bracket 314 to drive the second mounting bracket 314 to move in a direction closer to or away from the feeding module 10. The fifth drive unit 316 is disposed on the second mounting bracket 314 and moves with the second mounting bracket 314. The unloading plate 317 has a second conveying section 311. The unloading plate 317 is located above the second mounting bracket 314, and the fifth drive unit 316 is drivenly connected to the unloading plate 317 to drive the unloading plate 317 to move in a direction closer to or away from the conveying assembly 32. In this way, the fourth drive unit 315 drives the second mounting bracket 314 to move on the base 313, so that the conveying component 32, the fifth drive unit 316 and the ejector plate 317 set on the second mounting bracket 314 move together in the direction of approaching or moving away from the feeding module 10, so that the conveying component 32 moves towards the feeding module 10 to the lower part of the feeding end, catches and conveys the material head 12 of the adhesive. The fifth drive unit 316 drives the ejector plate 317 to move on the second mounting bracket 314, so that the ejector plate 317 moves in the direction of approaching or moving away from the conveying component 32, so as to drive the material tail on the ejector plate 317 towards the material head 12 to achieve overlap.

[0063] Preferably, both the fourth drive unit 315 and the fifth drive unit 316 are cylinders.

[0064] It should be noted that in this embodiment, the second mounting bracket 314 includes a first slider 3141. The second mounting bracket 314 is slidably connected to the slide rail on the base 313 through the first slider 3141, so that the second mounting bracket 314 can move in the direction of approaching or moving away from the feeding module 10.

[0065] It should be noted that in this embodiment, the ejector assembly 31 further includes a connecting frame 318 and a baffle plate 319. The driving end of the fifth driving unit 316 is connected to the ejector plate 317 through the connecting frame 318, thereby driving the ejector plate 317 to move in a direction closer to or further away from the conveying assembly 32. The ejector plate 317 is provided with two strip holes, which extend in a direction perpendicular to the conveying direction of the feeding module 30. Two baffle plates 319 are correspondingly disposed in the two strip holes. During the movement of the adhesive material, the two baffle plates 319 are located at both ends of the width direction of the adhesive material, and the distance between the two baffle plates 319 can be adjusted through the strip holes according to different types of adhesive material to ensure that the two baffle plates 319 are always located at both ends of the width direction of the adhesive material and play a guiding and limiting role in the movement of the adhesive material.

[0066] like Figure 6 As shown, the sewing module 40 includes a third mounting frame 41, a sixth driving unit 42, a seventh driving unit 43, a joint pressure plate 44, and a positioning baffle 45. The sixth driving unit 42 and the seventh driving unit 43 are respectively mounted on the third mounting frame 41. The sixth driving unit 42 is driven to move the joint pressure plate 44 in a direction closer to or further away from the conveying assembly 32. The seventh driving unit 43 is driven to move the positioning baffle 45 in a direction closer to or further away from the unloading assembly 31. Thus, the seventh driving unit 43 drives the positioning baffle 45 to move closer to the conveying assembly 32, fixing the material tail and stopping the material head 12 from moving. The sixth driving unit 42 drives the joint pressure plate 44 to move closer to the conveying assembly 32, pressing the material head 12 onto the material tail to achieve overlap.

[0067] like Figure 6 As shown, the joint pressure plate 44 and the positioning baffle 45 are parallel to each other and spaced apart along the conveying direction of the feeding module 30. In this way, the joint pressure plate 44 and the positioning baffle 45 can move toward the sewing module 40 respectively, preventing mutual interference.

[0068] It should be noted that, in this embodiment, the automatic feeding device also includes a conveying module 80, which is located at the end of the sewing module away from the feeding module 30, and the adhesive material on the feeding module 10 is conveyed to the conveying module 80.

[0069] like Figure 6As shown, the sewing module 40 also includes a second detection element 46, and the automatic feeding device also includes a second sensing element 70 that cooperates with the second detection element 46. The second sensing element 70 is disposed on the overlap portion 312. Thus, when the material tail passes between the second sensing element 70 and the second detection element 46, the control conveying module 80 stops moving, and the material tail stops moving. When the material head 12 passes between the second sensing element 70 and the second detection element 46, the control supply module 10 stops guiding the adhesive material, and the material head stops moving.

[0070] Preferably, the second sensing element 70 is a second reflector, and the second detection element 46 is a photoelectric switch.

[0071] It should be noted that in this embodiment, the sewing module 40 also includes a brush roller assembly 47 and a stop roller assembly 48. Both the brush roller assembly 47 and the stop roller assembly 48 are mounted on the third mounting bracket 41. The brush roller assembly 47 is located between the joint pressure plate 44 and the stop roller assembly 48. The adhesive material passes through the brush roller assembly 47 and the stop roller assembly 48 in sequence to move to the conveying module 80. The brush roller assembly 47 can prevent the material tail from curling up.

[0072] The automatic feeding device in this embodiment includes a correction process and an overlap process, wherein the correction process is as follows:

[0073] When the conveying module 80 is about to run out of material, the conveying speed of the conveying module 80 decreases, and the curtain moves forward slowly. The feeding module 30 rises upward under the action of the lifting module 20. When the second detection element 46 detects that the material tail has passed the second sensing element 70, the conveying module 80 stops moving, so that the edge of the material tail is in the square area of ​​the first reflector 61 on the unloading assembly 31. The fourth drive unit 315 drives the base 313, the fifth drive unit 316, the unloading plate 317, the connecting frame 318, the baffle plate 319, the overlapping part 312, the conveying assembly 32, and the correction assembly 33 to move together toward the feeding module 10. The first conveying section 321 of the conveying assembly 32 moves to below the feeding end of the feeding module 10. At this time, the third drive unit 322 drives the synchronous belt 325 to rotate. At the same time, the guide mechanism of the feeding module 10 drives the material head 12 to move downward. When the material head 12 contacts the synchronous belt 325, it is conveyed toward the material tail through the synchronous belt 325. When the second detection element 46 detects that the material head 12 has reached the second sensing element 70, the guide mechanism and the third drive unit 322 of the feeding module 10 stop, the material head 12 stops moving and the material roll rewinds slightly, so that the edge of the material head 12 is in the square area of ​​the first reflector 61 on the conveying assembly 32. At this time, the first photoelectric eye 51 detects the edge position of the material head 12, dist1, and the second photoelectric eye 52 detects the edge position of the material tail, dist2. The first control unit controls the movement of the correction assembly 33 according to the two position values. The first drive unit 332 drives the first lead screw 333 to rotate, and the lead screw nut 334 drives the first conveying section 321 to move and adjust along the width direction of the rubber material, so that the edges of the material head 12 and the material tail are aligned to achieve the correction purpose.

[0074] After the correction process, the overlapping process is carried out, as follows:

[0075] The fifth drive unit 316 drives the ejector plate 317 to move toward the material head 12 side via the connecting frame 318. A part of the ejector plate 317 moves to the top of the overlapping part 312. The seventh drive unit 43 drives the positioning baffle 45 to move downward. At this time, the material tail is below the positioning baffle 45, and the end of the material tail extends about 5 mm toward the material head 12 side relative to the positioning baffle 45. The third drive unit 322 drives the material head 12 on the synchronous belt 325 to be conveyed towards the material tail side. When the material head 12 touches the positioning baffle 45, the material head 12 and the material tail part overlap, with the material head 12 located above the material tail. The sixth drive unit 42 drives the joint pressure plate 44 to move downward, connecting the material head 12 and the material tail together. After the connection is completed, the positioning baffle 45 and the joint pressure plate 44 return upward. The fourth drive unit 315 drives the base 313, the conveying component 32 and the correction component 33 to move back in the direction away from the feeding module 10. The feeding module 30 descends under the action of the lifting module 20, and the feeding ends.

[0076] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: The feeding module 30 in this solution is lifted and moved to a specific position by the lifting module 20, so that one end of the feeding module 30 is located below the feeding end of the feeding module 10, so as to facilitate the receiving of the head 12 of the adhesive material from the feeding module 10. At least a part of the feeding module 30 can move relative to the lifting module 20 in a direction close to the feeding module 10 to move the tail of the material to the overlapping position. At least another part of the feeding module 30 can move in a direction perpendicular to the conveying direction of the feeding module 30, that is, along the width direction of the adhesive material, so as to align the edges of the head 12 and the tail of the material in the width direction. At least a part of the sewing module 40 can move in a direction close to the feeding module 30 to overlap the head 12 of one adhesive material and the tail of another adhesive material located on the feeding module 30. The material head 12 and the material tail overlap under the action of the sewing module 40. The material head 12 does not need to be placed in a fixed position before feeding, which can achieve the purpose of automatic feeding. The automatic feeding device has better performance, saves production costs, and is conducive to promotion and use.
