Detailed implementation mode

[0025] The core of the present invention is to provide an automatic tread replenishing device to solve the problem that the tread replenishing in the tire forming process affects the production efficiency.

[0026] In order to enable those skilled in the art to better understand the technical solutions provided by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figure 1 and Figure 2 As shown, the embodiment of the present invention provides an automatic tread replenishing device, including a replenishing material frame 1, a conveying platform 2 for conveying tread materials, a swing arm 3, a swing frame 4 and a clamping assembly 5; the conveying platform 2 is arranged on the replenishing material frame 1 and above the replenishing material frame 1, and a pressure roller assembly 6 for pressing the material head delivered to the conveying platform 2 is also arranged above the conveying platform 2; one end of the swing arm 3 is hinged to the replenishing material frame 1; the other end of the swing arm 3 is a free end, and the free end can swing around the hinged end of the swing arm 3; a first driver 7 for driving the free end to swing is also arranged between the swing arm 3 and the replenishing material frame 1; the swing frame 4 is arranged at the free end; the clamping assembly 5 is used for clamping and releasing the material head of the new tire tread roll, the clamping assembly 5 is rotatably arranged on the swing frame 4, and the clamping assembly 5 is connected with a second driver 8 for driving the clamping assembly 5 to rotate.

[0028] In the actual application process of this automatic tread feeding device, when the tread feeding equipment needs to perform a feeding operation, first, the first driver swings the swing arm on the rack to the feeding position of the new tread material roll. The clamping component remains in the release state to feed the head of the new tread material roll into the clamping component. After the head is fed into the clamping component, it remains in the clamped state. Then, the first driver drives the swing arm to swing upward, and at the same time, the second driver drives the clamping component to swing, so that the new tread material roll clamped by the clamping component remains horizontal until the head of the new tread material roll reaches the position of the conveying platform when the swing arm swings. Then, the head is pressed tightly by the pressure roller component and then conveyed to the subsequent process by the conveying platform. The entire tread feeding process is mainly completed by the automatic feeding device itself, which greatly shortens the tread feeding time, and then shortens the shutdown time of the whole machine, greatly improving the automation degree and production efficiency.

[0029] It should be noted here that the first driver and the second driver can specifically adopt linear drive cylinders, such as linear drive cylinders or linear drive oil cylinders, and can also adopt other linear drive mechanisms commonly used by those skilled in the art, such as the way of a motor-driven lead screw mechanism, etc. No more specific limitations are made here. In addition, the way of a servo motor driving the swing can also be adopted. In the actual application process, it can be selected according to actual needs, and no more specific limitations are made here.

[0030] In some specific implementation schemes, the aforementioned automatic tread feeding device may further include a pay-off carriage 9. The pay-off carriage 9 is located in the feeding area of the feeding rack 1 and is used to load the tread material roll and can export and feed the head of the new tread material roll into the clamping component 5. By automatically guiding the head by the pay-off carriage, the automatic feeding device becomes more intelligent, reduces manual operations, reduces labor, and improves work efficiency. It should be noted that the pay-off carriage itself belongs to the prior art, and its specific structure may include a coil device, a pay-off device, and a peeling device. Among them, the coil device is used to load the tread material roll, the pay-off device is used to convey the tape of the tread material roll to the peeling device; the peeling device is used to peel the tread rubber of the tread material roll from the backing cloth, and the discharge end of the peeling device is connected to the clamping component in the feeding area. Of course, it can be understood that the above is only a specific example of the structure form of the pay-off carriage in the embodiment of the present invention. In the actual application process, other structure forms commonly used by those skilled in the art can also be adopted, and no more specific description is made here.

[0031] In some more specific embodiments, the foregoing automatic tread feeding device may further include an AGV cart, which is used to transport the unwinding cart 9 in the empty material state away and transport the unwinding cart 9 carrying a new tread fabric roll to the feeding area. It should be noted that the AGV cart is an intelligent transport cart and belongs to the prior art, so no more specific description will be given here. The control of the AGV cart can be completed through the control system equipped with the automatic feeding device. When the tread rubber on the unwinding cart corresponding to the tread feeding device is emptied, the AGV cart is controlled to tow away the unwinding cart and transport the unwinding cart carrying a new tread fabric roll to the position required by the feeding device, that is, the feeding area. A corresponding detector, such as a photoelectric switch assembly, can be provided on the unwinding cart, and the photoelectric switch assembly can be used to monitor whether the rubber on the unwinding cart is emptied.

[0032] In some specific embodiments, the specific structure of the foregoing clamping assembly 5 may include a clamping frame rotatably provided on the swing frame 4, and upper and lower clamping plates 51 and 52 arranged vertically opposite to each other are provided on the clamping frame; the upper clamping plate 51 is connected to a third driver 53 for driving the upper clamping plate 51 to move closer to and away from the lower clamping plate 52, and / or the lower clamping plate 52 is connected to a fourth driver 54 for driving the lower clamping plate 52 to move closer to and away from the upper clamping plate 51. The clamping and releasing operations of the clamping assembly can be realized through the third driver and / or the fourth driver. It should be noted that either the third driver or the fourth driver can be selected to be arranged alone, or both can be arranged at the same time. In the actual application process, it can be selected and arranged according to actual needs.

[0033] In some specific embodiments, the foregoing clamping assembly 5 may further include a sensor 55 for detecting whether a material head is fed in, such as a photoelectric switch. By designing this sensor, the clamping and releasing control of the clamping assembly can be made more intelligent. When the sensor detects that there is a material head between the upper and lower clamping plates of the clamping assembly, the third driver and / or the fourth driver can be controlled to act to realize the clamping operation of the clamping assembly. When no material head is detected, the third driver and / or the fourth driver are controlled to act to realize the releasing operation of the clamping assembly.

[0034] It should be noted that the sensor 55 can be specifically selected to be provided on the upper clamping plate 51, or on the lower clamping plate, or on the feeding frame, as long as it can realize whether there is a material head at the clamping assembly. In the actual application process, it can be selected and arranged according to actual needs, and no more specific limitation will be given here.

[0035] In some specific embodiments, the specific structure of the above-mentioned pressure roller assembly 6 may include a material pressing roller 61 and a fifth driver 62 for driving the material pressing roller 61 to move closer to and away from the conveying platform 2. By driving the material pressing roller with the fifth driver, the material head delivered to the conveying platform can be pressed and then conveyed to subsequent equipment. Of course, it can be understood that the structure of the above-mentioned material pressing roller is only a preferred example of the embodiments of the present invention. In actual application, other structural forms of pressure roller assemblies commonly used by those skilled in the art can also be selected.

[0036] In some specific embodiments, a deviation rectifying assembly 10 for rectifying the tread rubber material entering the conveying platform 2 may also be provided on the above-mentioned replenishing frame 1, and the deviation rectifying assembly 10 is used to connect with the starting end of the conveying of the conveying platform 2. By designing the deviation rectifying assembly, the stability of the conveying of the tread rubber material can be ensured, and skewing is avoided from affecting subsequent processes.

[0037] In a further embodiment, the specific structure of the above-mentioned deviation rectifying assembly 10 may include a universal roller group 10a arranged in parallel and a guiding member 10b provided on the universal roller group 10a. The universal roller group 10a is used to support the tread rubber material upstream of the conveying platform 2; the guiding member 10b divides the universal roller group 10a into several guiding channels to guide multiple tread rubber materials conveyed synchronously. By designing the deviation rectifying assembly into the structure form of a universal roller group, when the tread rubber material is conveyed, it can freely shift in the left-right direction, and then the adjustment of deviation rectification is more convenient. It should be noted here that those skilled in the art should be able to understand that the universal roller group is a conveying roller group formed by arranging multiple universal rollers in parallel. Among them, the specific structure of the universal roller is a structure form in which a number of sequentially arranged universal wheels are provided on the roller body. Then, during the conveying process of the tread rubber material, it can swing freely left and right, facilitating the left-right displacement adjustment of the tread rubber material during deviation rectification.

[0038] In some more specific embodiments, the above-mentioned swing frame 4 can be designed to be slidably matched with the swing arm, and a sixth driver 11 for driving the swing frame to slide along the extension direction of the swing arm is provided between the swing frame and the swing arm. By designing the structure form in which the swing frame and the swing arm are slidably matched, when the clamping assembly delivers the material head to the conveying platform, since the swing arm is swung to a certain specific position upward, the sixth driver can be used to drive the swing frame to slide along the swing arm, and then the material head of the tread rubber material can be closely attached to the conveying platform, making it more convenient for the material head to enter the pressure roller assembly.

[0039] It should be noted that the foregoing third driver, fourth driver, fifth driver, and sixth driver may specifically adopt a linear drive cylinder or a linear drive oil cylinder. In actual application, selection can be made according to actual needs, and no more specific limitations are made here.
