Description

Technical Field

[0001] The present invention relates to the technical field of tread feeding, and in particular to a tread feeding device and a tread feeding method. Background Art

[0002] In the all-steel three-drum forming system, the function of the tread feeder is to convey the tread to the belt drum. In the application of the feeding system, the tread can be stored in the following forms: 1. rolled on the I-shaped wheel; 2. stored in the grille car in a pre-cut form; 3. stored in the shutter car in a pre-cut form.

[0003] For the third situation mentioned above, that is, when the tread is stored in the shutter car in a pre-cut form, according to the different processes of the previous cutting process, the tread is stored in two states: the bonding surface facing up and the bonding surface facing down, and the bonding surface of the tread has a plastic lining to keep the tread fresh. Since the shutter car has no conveying function, it is necessary to manually or machine to replace manual labor to peel off the plastic lining of the tread and then transfer the tread to the tread bonding template. The plastic lining at the head of the tread must be peeled off manually, which requires the participation of the operator. During non-material preparation time, the operator waits for material preparation, resulting in a waste of labor costs. If the tread feeder is a rear-mounted type, since the belt layer feeder is located directly behind the belt layer drum, the tread feeder must be located above the belt layer feeder, which brings difficulties to the manual or machine, and also increases the tread preparation time and reduces the working efficiency of the molding machine equipment. Therefore, when the tread is stored in the shutter car in a pre-cut form, the tread feeder is a front-mounted feeding system. However, when the tread feeder is located in front of the drum, the width of the three-drum building machine is greatly lengthened, and the floor space of the building machine system is increased.

[0004] As mentioned above, the existing tread feeding rack has problems such as waste of labor costs, unreasonable layout leading to inconvenient manual operation or machine equipment setting, and large floor space. Summary of the invention

[0018] Further, step S1 includes: the shutter car is positioned by the positioning device and stops at the positioning position on the input side of the stripping conveyor device; the first transfer device descends, and the multiple first extension arms of the first transfer device descend relative to the main frame and enter into the gap between the conveying rollers of the stripping conveyor device.

[0019] Further, step S2 includes: the tread is peeled, centered and conveyed by the peeling mechanism, peeling centering mechanism and conveying roller of the peeling conveying device in the shutter car, until the front end of the tread reaches the peeling conveying detection part to trigger the peeling conveying detection part, and the tread stops conveying and is located above the first transfer device.

The three-drum forming machine formed by the tread feeding device of this embodiment does not exceed its length and width size requirements, thereby solving the problem that the front-mounted feeding system greatly lengthens the width of the three-drum forming machine.

DETAILED DESCRIPTION

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0035] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0036] In order to solve the problem of unreasonable layout of the tread feeding rack in the prior art, the present invention provides a tread feeding device and a tread feeding method.

[0037] like Figures 1 to 4The tread feeding device shown in the figure comprises: a main frame 10, a stripping conveying device 20 for cooperating with a conveying component, a storage and conveying device 30 for storing materials, a bonding template device 40 for conveying treads, a first transfer device 50, and a second transfer device 60. The main frame 10 has an installation area; the input side of the storage and conveying device 30 is located above the stripping conveying device 20; the bonding template device 40 is located at the output side of the storage and conveying device 30, and conveys the tread conveyed by the storage and conveying device 30 to the belt drum 70 for bonding, and the stripping conveying device 20, the storage and conveying device 30 and the bonding template device 40 are all located in the installation area; the first transfer device 50 is connected to the main frame 10 and can be lifted and lowered, and lifts and transfers the tread from the stripping conveying device 20 to the storage and conveying device 30; the second transfer device 60 is connected to the main frame 10 and can be moved laterally, and transfers the tread from the storage and conveying device 30 to the bonding template device 40.

[0038] In this embodiment, the shutter car 90 is used as a post-type tread feeding device for pre-cutting the full steel tread, and the structural device and layout of the tread feeding device are redesigned. The stripping conveying device 20 is arranged at the input side of the storage and conveying device 30 and below it, so that the stripping conveying device 20 can strip and convey the tread from the shutter car 90, and then lift it to the height of the storage and conveying device 30 through the first transfer device 50 and transfer it to the storage and conveying device 30, and the tread can be stored and conveyed in the storage and conveying device 30. Then, the bonding template device 40 is arranged at the output side of the storage and conveying device 30, so that when bonding is required, the second transfer device 60 can transfer the tread stored in the storage and conveying device 30 to the bonding template device 40, so that it is transported to the belt layer drum 70 through the bonding template device 40 for bonding, so as to achieve bonding. The above-mentioned setting mode redesigns the layout between the devices from the aspects of logical relationship, action process and reasonable layout of the transfer space, so that the tread feeding device can realize the functions of plastic lining cloth stripping and conveying of the tread, lifting and conveying of the tread, storage and conveying of the tread, horizontal transmission of the tread, and lamination on the belt drum 70. The functions of each module device are independent and the division of labor is clear, making the subsequent transformation and secondary design simple and convenient. Moreover, the logical order of tread access realizes the stack storage mode of "first in, first out", and the tread can be continuously stored in the storage position of the storage and conveying device 30, realizing the maximum utilization rate of each storage position of the storage and conveying device 30. At the same time, the storage and conveying device 30 provides a buffer area for the tread. Without changing the semi-finished product process, one operator can save 75% of the time to prepare the tread for the tread feeding device. In the case of frequent changes in tread specifications, the preparation time of the laminating template 42 can be greatly shortened, the working efficiency of the molding equipment is improved, and the waste of labor costs is avoided, which has a wide range of economic value. The three-drum forming machine formed by the tread feeding device of this embodiment does not exceed its length and width size requirements, thereby solving the problem that the front-mounted feeding system greatly lengthens the width of the three-drum forming machine.

[0039] In addition to optimizing the layout of the tread feeding device from a structural perspective, this embodiment also redesigns the logical relationship between its devices. Specifically, the stripping conveying device 20 includes a stripping conveying detection member 26, which controls the first transfer device 50 to operate when the stripping conveying detection member 26 detects that the tread is delivered to the right position, the storage and conveying device 30 includes a storage detection member 33, and the storage detection member 33 is located at the input side of the storage and conveying device 30. When the storage detection member 33 detects that the first transfer device 50 transfers the tread to the storage and conveying device 30, the storage and conveying device 30 controls the storage and conveying device 30 to perform a conveying action, and the second transfer device 60 includes a transfer detection member 63, and when the transfer detection member 63 detects that there is a tread on the second transfer device 60, the second transfer device 60 controls the second transfer device 60 to transfer the tread to the bonding template device 40. In this way, when the tread is fed, the stripping conveying device 20 conveys the tread, and the stripping conveying detection member 26 detects the predetermined position. When the tread is detected, it means that the tread is delivered to the right position. At this time, the stripping conveying device 20 can suspend the delivery, and the first transfer device 50 can be activated to transfer the tread from the stripping conveying device 20 to the storage and conveying device 30. Since the storage detection member 33 detects the input side of the storage and conveying device 30, when the tread is transferred to the storage and conveying device 30, the storage detection member 33 detects that the tread is transferred to the storage and conveying device 30. At this time, the storage and conveying device 30 can be activated to transfer the tread, so that the tread is transported to the storage position of the storage and conveying device 30 to avoid accumulation at the input side. When bonding is required, the second transfer device 60 is activated to transfer the nearest tread from the storage and conveying device 30 to the bonding template device 40, and then the bonding template device 40 is used to transport and bond. The above-mentioned tread detection method and the control logic relationship between the actions of each device are reasonable, the lifting and conveying function and the storage and conveying function are closely coordinated, and the horizontal transmission function is independent, which makes the control program logic design concise and clear, and facilitates subsequent program upgrades.

[0040] Each detection element described in this embodiment can be a sensor or other component as needed.

[0041] like Figure 1 and Figure 2As shown, in this embodiment, the stripping conveying device 20 is responsible for completing the stripping, centering, and conveying operations on the tread of the shutter vehicle 90. The stripping conveying device 20 includes: a conveying frame 21, a stripping mechanism 22, a stripping centering mechanism 23, a conveying roller 24, a stripping conveying driving member 25, and a stripping conveying detection member 26. Among them, the conveying frame 21 serves as a mounting carrier for the other parts of the stripping conveying device 20, and has a supporting part and a bearing part. The supporting part of the conveying frame 21 includes a plurality of vertically arranged and mutually spaced support columns, and a horizontal connecting beam arranged between the bottom and the top of the support column, so that the supporting part of the entire conveying frame is an integrated structure, so that when the conveying frame 21 plays the role of a mounting carrier for the other parts of the stripping conveying device 20, it will not be deformed, ensuring the stability of the structure. The connecting beams and support columns of the supporting part of the conveying frame roughly form a hexahedral frame structure in three-dimensional space. The two faces with the narrowest width and the longest length in the hexahedral structure are arranged horizontally, forming a lower face close to the ground and a corresponding upper face away from the ground. The bearing part of the conveying frame 21 is arranged on the upper surface of the supporting part. The bearing part has two side walls extending along the length direction of the upper surface of the supporting part. The two side walls are flush with the long sides of the upper surface of the supporting structure, and serve as the main part connecting the conveying frame 21 with other components. The conveying roller 24 is arranged between the two side walls of the bearing part of the conveying frame, and a plurality of conveying rollers 24 can be provided, and the upper surfaces of the conveying rollers 24 together form a conveying surface for conveying the tread. Each conveying roller 24 is rotatably connected to the two side walls of the bearing part. The axis of the conveying roller 24 is perpendicular to the conveying direction. The plurality of conveying rollers 24 are arranged in sequence along the conveying direction and there is a certain gap between each conveying roller 24. In this way, when the stripping conveying device 20 is in operation, the conveying rollers 24 rotate to carry and convey the tread. The stripping conveying driving member 25 can be a motor, etc., and the stripping conveying driving member 25 is connected to the conveying roller 24. When the tread is transported, the stripping conveying driving member 25 drives the conveying roller 24 to rotate to realize the rotation of the conveying roller 24 to complete the operation of transporting the tread.

[0042] In this embodiment, the conveying frame 21 has an input side for receiving the tread and a terminal side for limiting the tread from running to and leaving the stripping conveying device 20. The stripping mechanism 22 is arranged at the input side to perform a stripping operation on the tread and the plastic lining cloth thereon that are conveyed to the conveying frame 21. The stripping centering mechanism 23 is also arranged at a position close to the input side. The stripping centering mechanism 23 corrects the offset of the tread in the length direction relative to the stripping conveying device 20 through a centering operation, so that the length direction of the tread is consistent with the conveying direction of the stripping conveying device 20. The stripping mechanism 22 is closer to the entrance of the input side than the stripping centering mechanism 23, and a stripping pressure roller is arranged between the two. That is to say, when the tread is conveyed to the conveying frame 21, it is first stripped by the stripping mechanism 22, and the stripping pressure roller plays the role of pressing the material, and then the stripping centering mechanism 23 performs centering and conveying. Different from the above, the stripping conveying detection member 26 is arranged at the end side of the stripping conveying device 20. After the stripping conveying detection member 26 detects the end of the tread, the stripping conveying driving member 25 stops driving the conveying roller 24 to rotate, and the tread stops at a predetermined end position. The above-mentioned stripping mechanism 22, the stripping centering mechanism 23, and the stripping conveying detection member 26 are all connected to the conveying frame 21.

[0043] like Figure 3 As shown, the stripping mechanism 22 of this embodiment includes a stripping roller 29, a stripping roller driving member 27 and a stripping electric roller 28. The stripping roller 29, the stripping roller driving member 27 and the stripping electric roller 28 are all arranged on a vertical column. The stripping roller 29 can swing and rotate, and can clamp and convey the plastic lining cloth on the tread; the stripping roller driving member 27 is drivingly connected to the stripping roller 29, and drives the stripping roller 29 to swing to clamp and convey the plastic lining cloth; the stripping electric roller 28 can be rotatably arranged and docked with the stripping roller 29 to clamp the plastic lining cloth. After clamping the plastic lining cloth, the stripping electric roller 28 can drive itself to rotate, thereby stripping the plastic lining cloth on the tread, solving the problem of stripping the plastic lining cloth on the tread in the traditional method, and realizing the stripping of the plastic lining cloth. Moreover, this method is applicable to the state of the tread regardless of whether the bonding surface is facing up or facing down.

[0044] In this embodiment, a positioning device 80 is provided directly in front of the input side of the stripping conveying device 20. The positioning device 80 is used to position the shutter car 90 with the pre-cut tread. When the shutter car 90 delivers the material into place, the positioning device 80 stops the shutter car 90 at the positioning position to facilitate the next feeding operation.

[0045] like Figure 1 and Figure 4As shown, in this embodiment, the function of the first transfer device 50 is to complete the transportation of the tread from the stripping conveying device 20 to the storage and conveying device 30. The first transfer device 50 includes: a first frame 51, a plurality of first extension arms 52, a first extension drive member 53, and a first lifting drive member 54. The first frame 51 is a mounting carrier for other components in the first transfer device 50. The length direction of the first frame 51 is horizontally arranged. The first frame 51 is connected to the main frame 10 and can move up and down relative to the main frame 10. The first extension arm 52 is installed on the first frame 51. The first extension arm 52 can be telescopically moved in a nearly horizontal direction, and the moving direction of the first extension arm 52 is substantially perpendicular to the length direction of the first frame 51. Of course, the moving mode and direction of the first extension arm 52 can be adjusted as needed, as long as it can be extended under the tread to lift the tread. The first extension drive member 53 is drivingly connected to the first extension arm 52 and drives the first extension arm 52 to move laterally relative to the first frame 51. The first lifting drive member 54 is drivingly connected to the first frame 51, and drives the lifting movement of the first frame 51. The first extension drive member 53 and the first lifting drive member 54 can be specifically made of motors and other components as needed.

[0046] like Figure 1 As shown, in this embodiment, the storage and conveying device 30 includes: a plurality of conveyor belts 31, a storage and conveying driving member 32, and a storage detection member 33. The storage and conveying device 30 is installed on the main frame 10, and has an input side for receiving the tread, an output side for sending the tread, and a storage area between the input side and the output side. The storage and conveying device 30 has a plurality of conveyor belts 31 arranged in parallel and spaced apart. The conveying directions of the conveyor belts 31 are all parallel, and their conveying directions are the straight line direction from the stripping conveying device 20 to the bonding template device 40. The length of the conveyor belt 31 itself extends along the conveying direction, and the width direction of the conveyor belt 31, that is, the arrangement direction between the conveyor belts 31 and the conveying direction of the conveyor belt 31 adopts a non-parallel setting mode. In this embodiment, the two are perpendicular to each other, so that when the conveyor belt 31 rotates, the tread can be driven to move, and the tread is transported from the input side to the output side. The storage and conveying driving member 32 is connected to the conveyor belt 31 by driving, and the conveyor belt 31 is driven by the storage and conveying driving member 32 to realize the conveying movement. The material storage detection member 33 is disposed at the input side of the conveyor belt 31 , and controls the storage and conveying device 30 to perform a conveying action when the material storage detection member 33 detects that the first transfer device 50 transfers the tread to the storage and conveying device 30 .

[0047] In this embodiment, the conveying rollers 24 of the stripping conveying device 20 are arranged at intervals, and the conveying belts 31 of the storage and conveying device 30 are also arranged at intervals. At the same time, the first extension arm 52 is also arranged at multiple intervals, so that the first extension part together forms a claw-like structure. Specifically, in the up and down direction, the gap between the conveying rollers 24 and the gap between the conveying belts 31 are aligned up and down, and the first extension arm 52 is located in the gap. In this way, when the first transfer device 50 moves up and down, the first extension arm 52 can extend into or out of the gap between the conveying rollers 24 and the gap between the conveying belts 31. When the first transfer device 50 is located at the stripping conveying device 20, the first extension arm 52 is located in the gap between the conveying rollers 24. At this time, the tread can be normally conveyed on the conveying rollers 24 to the top of the first extension arm 52. Then, when the stripping conveying detection member 26 detects the tread, the conveying rollers 24 stop conveying, and the first extension arm 52 moves upward to lift the tread from below the tread, so as to realize the upward conveying of the tread. Similarly, after the first extending arm 52 conveys the tread to a height slightly higher than the conveyor belt 31, the first extending arm 52 moves horizontally to convey the tread above the conveyor belt 31, and then the first extending arm 52 extends downward into the gap between the conveyor belts 31, so that the tread can be placed on the conveyor belt 31, and then the first extending arm 52 can be disengaged from the tread downward, thereby completing the conveying and transferring of the tread on the conveying roller 24 to the conveyor belt 31. Compared with the traditional suction cup structure, the above method can reduce the deformation of the tread and ensure the stable transfer of the tread.

[0048] In this embodiment, the storage and conveying device 30 includes a plurality of storage positions, some of which are arranged in the conveying direction of the storage and conveying device 30, and some of which can be arranged along the arrangement direction between the conveyor belts 31, that is, storage positions can be set along the length direction and width direction of the conveyor belt 31. In this way, the storage and conveying device 30 can be provided with more storage positions, and the tread can be conveyed to the corresponding storage position as the conveyor belt 31 is conveyed, so as to realize material storage. Of course, the storage positions can also be set only along the length direction of the conveyor belt 31.

[0049] The storage positions of this embodiment include the initial storage position, the intermediate storage position and the final storage position which are sequentially arranged along the conveying direction of the storage and conveying device 30, wherein the first storage position arranged in the direction from the input side to the output side of the storage and conveying device 30 is the initial storage position; the last storage position arranged in the direction from the input side to the output side of the storage and conveying device 30 is the final storage position; the storage positions arranged between the initial storage position and the final storage position and located in the storage area are all intermediate storage positions. Generally, there is only one initial storage position and one final storage position for a row of storage positions, while there can be multiple intermediate storage positions, thereby realizing large-scale storage.

[0050] Based on the setting of the above-mentioned material storage position, the storage and conveying device 30 of this embodiment, in addition to the above-mentioned material storage detection member 33, also includes an intermediate detection member and a final position detection member. Different from the material storage detection member 33, the final position detection member is arranged at the output side of the storage and conveying device 30, and the intermediate detection member is arranged between the material storage detection member 33 and the final position detection member. The intermediate detection member, the final position detection member and the above-mentioned material storage detection member 33 have a specific position setting method. Specifically, the material storage detection member 33 is arranged at the initial material storage position, the final position detection member is arranged at the final material storage position, and the intermediate detection member is arranged at the intermediate material storage position. In other words, the material storage detection member 33 and the final position detection member are respectively arranged at the two ends of the storage and conveying device 30, and the intermediate detection member is located in the middle. The above three detection members are all used to detect whether there is material or other material status at the material storage position. Under such a position setting mode, when the storage detection member 33 detects that there is a tread at the initial storage position, it means that the first transfer device 50 transfers the tread to the storage and conveying device 30. At this time, the storage and conveying device 30 is controlled to perform the conveying action, so that the tread is conveyed and stored in time; and the last position detection member detects the material state of the last storage position. When the last position detection member detects that there is a tread at the last storage position, it means that the last storage position has stored a tread. At this time, the storage and conveying device 30 is controlled to stop conveying, so as to avoid over-conveying. At the same time, the storage detection member 33 also has the function of counting the number of stored treads, and transmits communication signals with the second transfer detection member 63 to confirm twice that the second transfer device 60 has taken away the nearest tread.

[0051] Optionally, there is one initial material storage position, one or more material storage detection members 33, and each initial material storage position is provided with a material storage detection member 33; and / or there are multiple intermediate material storage positions, multiple intermediate detection members, and each intermediate material storage position is provided with an intermediate detection member; and / or there are one or more final material storage positions, one or more final detection members, and each final material storage position is provided with a final detection member. This embodiment adopts a method in which each material storage position is provided with a detection member, thereby ensuring accurate detection of the material storage status of each material storage position.

[0052] like Figure 1 and Figure 4As shown, in this embodiment, the structure of the second transfer device 60 is substantially the same as that of the first transfer device 50, and the second transfer device 60 further includes: a second frame 61, a plurality of second extension arms 62, a transfer detection member 63, a second lifting drive member 64, and a second horizontal drive member 65. The second frame 61 is a mounting carrier for other components in the second transfer device 60. The length direction of the second frame 61 is horizontally arranged, and its length direction is perpendicular to the conveying direction of the conveyor belt 31 of the storage and conveying device 30. The second frame 61 is connected to the main frame 10 and can move laterally relative to the main frame 10. The moving direction of the second frame 61 is perpendicular to its own length direction, that is, parallel to the conveying direction of the conveyor belt 31, so that the second frame 61 moves between the upper part of the storage and conveying device 30 and the upper part of the bonding template device 40 to realize the conveying of the tread. At the same time, the second frame 61 also has a small lifting movement, so that the tread can be lifted off the conveyor belt 31 and placed on the bonding template device 40. The second extension arm 62 is connected to the second frame 61, and the two can be fixedly connected so that the two can move synchronously. In this way, the second frame 61 and the second extension arm 62 can move up and down and horizontally so that the second extension arm 62 can lift the tread to achieve the transfer of the tread. The second lifting drive 64 and the second horizontal drive 65 are both connected to the second frame 61, so that the lifting movement of the second frame 61 is driven by the second lifting drive 64, and the horizontal movement of the second frame 61 is driven by the second horizontal drive 65, so that the second frame 61 and the second extension arm 62 can move synchronously up and down and horizontally. The transfer detection member 63 is located on the second frame 61 or the second extension arm 62, and when the tread is detected on the second transfer device 60, it controls the second transfer device 60 to transfer the tread to the bonding template device 40.

[0053] like Figure 1As shown, in this embodiment, the laminating template device 40 includes: a conveying template 41, a laminating template 42, and a laminating centering device 43. The conveying template 41 is arranged at the output side of the storage and conveying device 30, and the conveying direction of the conveying template 41 is perpendicular to the conveying direction of the conveyor belt 31, so that the conveying direction of the laminating template 42 is parallel to the conveying direction of the conveying roller 24, but the conveying trajectory lines of the two do not overlap. The laminating template 42 is docked with the conveying template 41, and the conveying template 41 conveys the tread to the laminating template 42. The laminating template 42 is located at one end of the conveying template 41 close to the belt drum 70, and the laminating template 42 can be swung relative to the main frame 10. In this way, the laminating template 42 can be swung during laminating to change the laminating angle, ensuring that the position between the tread and the belt drum 70 meets the laminating requirements. The laminating centering device 43 is located between the conveying template 41 and the laminating template 42, and centers the tread so that the length direction of the tread is consistent with the conveying direction. The swing driving member 44 is drivingly connected to the bonding template 42 and drives the bonding template 42 to swing so that the tread angle is consistent with the bonding requirement.

[0054] It should be noted that the specific structures of the above-mentioned peeling conveying device 20, template laminating device 40, first transfer device 50, second transfer device 60 and other devices in this embodiment can be adjusted accordingly as needed and are not limited to the settings of this embodiment.

[0055] In this embodiment, the above-mentioned parts constituting the tread feeding device have a new and specific setting method. The specific setting method is as follows: the tread feeding device has an oncoming direction defined by a shutter car 90 and a delivery direction perpendicular to the oncoming direction and pointing from the left side of the oncoming direction to the tread feeding position on the right side of the oncoming direction. Extending along the oncoming direction, the tread feeding device is closest to the oncoming direction of the vehicle, and continues to extend. The stripping conveying device 20 is at the farther end in the oncoming direction. The input side of the stripping conveying device 20 is closer to the oncoming direction than the terminal side. The conveying direction of the stripping conveying device 20 is consistent with the oncoming direction. At the same time, the stripping conveying device 20 is at the closest end except the main frame 10 in the delivery direction; a storage and conveying device 30 is arranged directly above the stripping conveying device 20. The distance of the storage and conveying device 30 in the oncoming direction is basically consistent with that of the stripping conveying device 20. The arrangement direction of the conveyor belt 31 of the storage and conveying device 30 and the length direction of the tread on the device are parallel to the oncoming direction. The conveying direction of the storage and conveying device 30 is perpendicular to the direction of the oncoming vehicle and points to the template laminating device. At the same time, the distance of the storage and conveying device 30 in the delivery direction is basically consistent with that of the stripping conveying device 20. The input side of the storage and conveying device 30 is closer to the proximal end of the delivery direction than the output side of the storage and conveying device 30, and the conveying direction of the storage and conveying device 30 is consistent with the delivery direction. A template laminating device 40 is also arranged at the same height of the storage and conveying device 30. The template laminating device 40 is at a farther end than the storage and conveying device 30 in the delivery direction. The conveying direction of the conveying template 41 of the template laminating device 40 is perpendicular to the delivery direction and is consistent with the oncoming vehicle direction and points to the far end of the oncoming vehicle direction. The first transfer device 50 is arranged on the main frame 10, the length direction of the first frame 51 is parallel to the direction of the vehicle, the telescopic direction of the first extension arm 52 is parallel to the delivery direction, and the initial position of the first transfer device 50 is located directly above the stripping conveyor 20. Its distance in the direction of the vehicle and the delivery in three-dimensional space is roughly the same as the input side of the stripping conveyor 20 and the storage and conveying device 30, and it can move up and down in the vertical direction perpendicular to these two directions. The second transfer device 60 is also arranged on the main frame 10, the length direction of the second frame 61 is parallel to the direction of the vehicle, and the translation direction of the second frame 61 and the second extension arm 62 is parallel to the delivery direction. The second transfer device 60 can move up and down or reciprocate in a direction parallel to the delivery direction.

[0056] The present embodiment also provides a tread feeding method, which adopts the above-mentioned tread feeding device, and the tread feeding method includes: step S1: the shutter car 90 as a conveying component and storing the pre-cut tread is docked with the stripping conveying device 20, and the first transfer device 50 is lowered and docked with the stripping conveying device 20; step S2: the stripping conveying device 20 is actuated to convey the tread on the shutter car 90 to the first transfer device 50; step S3: the first transfer device 50 rises to convey the tread to the storage and conveying device 30; step S4: the storage and conveying device 30 conveys the tread to the storage position for storage or further conveying; step S5: during further conveying, the second transfer device 60 moves laterally to the output side of the storage and conveying device 30, and transfers the tread from the storage and conveying device 30 to the bonding template device 40; step S6: the bonding template device 40 conveys the tread to the belt layer drum 70 for bonding.

[0057] Specifically, the above process is:

[0058] Step S1 includes: the shutter car 90 is positioned by the positioning device 80 and stops at the positioning position on the input side of the stripping conveying device 20; the first transfer device 50 descends, and the multiple first extension arms 52 of the first transfer device 50 descend relative to the main frame 10 and enter into the gap between the conveying rollers 24 of the stripping conveying device 20.

[0059] Step S2 includes: the tread is peeled, centered and conveyed by the peeling mechanism 22, the peeling centering mechanism 23 and the conveying roller 24 of the peeling conveying device 20 in the shutter car 90, until the front end of the tread reaches the peeling conveying detection part 26 to trigger the peeling conveying detection part 26, and the tread stops conveying and is located above the first transfer device 50.

[0060] Step S3 includes: the first extending arm 52 of the first transfer device 50, driven by the first lifting drive member 54, lifts the tread to a height higher than the storage and conveying device 30; driven by the first extending drive member 53, the first extending arm 52 extends horizontally to transfer the tread to directly above the storage and conveying device 30; the first lifting drive member 54 drives the first extending arm 52 to descend, and the first extending arm 52 enters the gap between the conveyor belts 31 of the storage and conveying device 30 to place the tread on the first storage position on the input side of the storage and conveying device 30; after the first transfer device 50 is lower than the upper surface of the conveyor belt 31, the first extending drive member 53 drives the first extending arm 52 to retract.

[0061] Step S4 includes: when the storage detection member 33 of the initial storage position of the storage and conveying device 30 detects the tread and the last detection member of the last storage position does not detect the tread, the storage and conveying driving member 32 drives the conveyor belt 31 to convey one storage position along the conveying direction, repeats the above actions, and continuously stores the tread in each storage position of the storage and conveying device 30 for storage; until the last detection member of the last storage position detects the tread, the storage and conveying driving member 32 stops driving. When only the storage detection member 33 detects the tread, and neither the middle detection member nor the last detection member detects the tread, it means that there is a tread only on the initial storage position, and the communication unit sends a signal to the stripping conveying device 20 to continue stripping the tread, and at the same time, the storage and conveying driving member 32 drives the conveyor belt 31 to convey the tread on the initial storage position by one storage position along the conveying direction, and waits for the next tread to be stored.

[0062] Step S5 includes: after receiving the material-taking signal, the second lifting drive 64 drives the second extending arm 62 to descend, so that the second extending arm 62 is lower than the upper surface of the storage and conveying device 30; the second horizontal drive 65 drives the second extending arm 62 to the storage and conveying device 30 to take the material; when the transfer detection member 63 detects the nearest tread, the second horizontal drive 65 drives the second extending arm 62 to stop moving after a predetermined distance, and the specific size of the predetermined distance can be set as needed, as long as it is ensured that the second transfer device 60 can take away treads of different specifications; the second lifting drive 64 drives the second extending arm 62 to rise, so that the second extending arm 62 is high On the upper surface of the storage and conveying device 30, the tread is transferred to the second extending arm 62; the second horizontal driving member 65 drives the second extending arm 62 to move to directly above the bonding template 42; the second lifting driving member 64 drives the second extending arm 62 to descend, so that the second extending arm 62 is lower than the conveying plane of the bonding template 42, and the tread is transferred to the bonding template 42, and the bonding template 42 is ready for material preparation; the second horizontal driving member 65 drives the second extending arm 62 to detach from the bonding template 42; the second lifting driving member 64 drives the second extending arm 62 to rise; the second horizontal driving member 65 continues to drive the second extending arm 62 to return to the initial position, waiting for the next material picking signal.

[0063] Step S6 includes: after the bonding template 42 of the bonding template device 40 receives the tread, the tread is centered again by the bonding centering device 43, the bonding template 42 continues to be transported, the swing drive 44 drives the bonding template 42 to swing, and finally the tread is bonded to the belt layer drum 70 at the optimal bonding angle.

[0064] In this embodiment, the main process steps of the tread feeding device are as follows:

[0065] The shutter car 90 with the pre-cut tread is positioned by the positioning device 80 and stops in front of the input side of the stripping conveying device 20; the first transfer device 50 descends, and the multiple first extension arms 52 of the first transfer device 50 extend relative to the first frame and enter the gap between the conveying rollers 24 of the stripping conveying device 20. The tread is stripped, centered and conveyed from the shutter car 90 through the stripping mechanism 22, the stripping centering mechanism 23 and the conveying rollers 24 of the stripping conveying device 20 until the front end of the tread reaches the conveying detection member and stops, and the tread reaches the predetermined position in a predetermined shape.

[0066] The first transfer device 50, driven by the first lifting drive member 54, lifts the tread to a height slightly higher than the storage and conveying device 30, and then, driven by the first extending drive member 53, the first extending arm 52 extends horizontally to transfer the tread to directly above the storage and conveying device 30, and the first lifting drive member 54 continues to drive the first transfer device 50 to descend, and places the tread on the first storage position on the input side of the storage and conveying device 30, and the first extending arm 52 of the first transfer device 50 enters the gap between each conveyor belt 31, and the first transfer device 50 is lower than the upper plane of the conveyor belt 31 of the storage and conveying device 30, and then the first extending drive member 53 drives the first extending arm 52 to retract, and the first lifting drive member 54 continues to drive the first transfer device 50 to descend between the conveying rollers 24, waiting for the next tread.

[0067] In this embodiment, the gaps between the multiple parallel conveyor belts 31 of the storage and conveying device 30 are for the first extension arm 52 and the second extension arm 62 of the first transfer device 50 and the second transfer device 60 to enter. The storage detection member 33 is located at the input side of the storage and conveying device 30, and each input side position is provided with a storage detection member 33. When the storage detection member 33 detects that the first transfer device 50 transfers the tread to the storage and conveying device 30, the storage and conveying device 30 is controlled to perform a conveying action; the last position detection member is located at the last storage position on the output side of the storage and conveying device 30. The last position detection member detects the material state of this storage position. When the last position detection member detects that there is a tread at this storage position, the storage and conveying device 30 is controlled to stop conveying. The conveying action of the storage and conveying device 30 refers to the storage and conveying driving member 32 of the storage and conveying device 30 driving the multiple conveyor belts 31 to convey a storage position in the conveying direction. The moving distance is a fixed value set in advance, and the distance is the width of each storage position. By repeating the above conveying action, the tread can be continuously stored in all storage positions of the storage and conveying device 30. When the last position detection member of the last storage position in the conveying direction detects the tread, the storage conveying drive member 32 stops driving, and the storage position of the storage and conveying device 30 is full.

[0068] The length, width and thickness of the tread rubber material vary according to different specifications. Since the material head of the tread has been positioned by the stripping conveying detection member 26 on the input side of the stripping conveying device 20, and the center line has been centered and positioned by the stripping centering mechanism 23 of the stripping conveying device 20, treads of different specifications can be detected by the storage detection member 33.

[0069] The storage and conveying device 30 of this embodiment is mainly used to realize the temporary buffer area of ​​the tread on the feeding rack. In this embodiment, the operator only needs to peel off the plastic lining cloth at the head of the tread, and the rest of the work is completed by the tread feeding device. The cycle of laminating the full steel tread to the belt drum 70 is 100 to 150 seconds, and the time to store a tread on the storage and conveying device 30 is about 20 to 30 seconds. The operator can concentrate on transferring multiple treads from the shutter car 90 to the storage and conveying device 30, and then do other work, avoiding the waste of labor costs.

[0070] When the second transfer device 60 is not in operation, it is located between the bonding template 42 and the storage and conveying device 30, that is, at the zero point. After receiving the material-picking signal, the second lifting drive 64 drives the second transfer device 60 to descend, so that the second transfer device 60 is lower than the upper plane of the storage and conveying device 30; the second horizontal drive 65 drives the second transfer device 60 to the storage and conveying device 30 area to pick up materials; when the transfer detection member 63 detects the tread, the second horizontal drive 65 drives the second transfer device 60 to continue moving a certain distance and then stops moving. The distance is a preset fixed value, which can ensure that the second transfer device 60 can take away treads of different specifications; the second lifting drive 64 drives the second transfer device 60 to rise, so that the second transfer device 60 is higher than the upper plane of the storage and conveying device 30, and the tread is transferred to the second transfer device The second horizontal driving member 65 drives the second transfer device 60 to move to the top of the bonding template 42; the second lifting driving member 64 drives the second transfer device 60 to descend, so that the second transfer device 60 is lower than the conveying upper plane of the bonding template 42, and the tread is transferred to the bonding template 42, and the bonding template 42 completes the preparation of a tread, which greatly shortens the preparation time of the bonding template and improves the working efficiency of the molding equipment; the second horizontal driving member 65 continues to drive the second transfer device 60 to leave the bonding template 42; the second lifting driving member 64 drives the second transfer device 60 to rise; the second horizontal driving member 65 continues to drive the second transfer device 60 to return to the zero position, waiting for the next material picking signal.

[0071] The detection member 63 is transferred from the zero point to the storage and conveying device 30 area for detection. The detected tread is the tread closest to the fitting template 42. Therefore, the tread can realize the "first in, first out" storage principle on the storage and conveying device 30. This storage method is mainly to maximize the utilization rate of each storage position of the storage and conveying device 30.

[0072] After the tread feeding device laminating template 42 has prepared the material, it is centered again by the laminating centering device 43, the laminating template 42 is conveyed forward, and the swing driving member 44 drives the laminating template 42 to swing, so that the tread is automatically laminated to the belt drum 70 at the optimal laminating angle. In this embodiment, the conveying member of the laminating template 42 can be a conveying roller or a bidirectional bearing string.

[0073] The belt layer feeding rack matched with the tread feeding device of the present embodiment can be an automatic lower laminating belt layer feeding rack, an automatic upper laminating belt layer feeding rack or a manual belt layer feeding rack, etc.

[0074] It should be noted that, the multiple in the above embodiments refers to at least two.

Without changing the semi-finished product process, one operator can save 75% of the time to prepare the tread for the tread feeding device, which greatly shortens the preparation time for the bonding template, improves the working efficiency of the molding equipment, avoids the waste of labor costs, and has a wide range of economic value;
