Description

Technical Field

[0001] The invention belongs to the technical field of rubber product processing, and in particular relates to a buffering process with selectable buffering amount for continuous production of rubber products. Background Art

[0002] At present, in the production and processing of rubber products (rubber belts), it is necessary to add corresponding receiving and sending mechanisms at the entry and exit ends of each process to meet the connection between various processes in the assembly line operation.

[0003] However, in the process of receiving and sending out each process, the structure used only plays the role of transmission guidance. Once a problem occurs in a process or online maintenance is required, the machine must be stopped for processing. As a result, the following technical defects exist:

[0004] 1. When a problem occurs in one process, the adjacent processes must also be shut down, which may directly cause production to stop and affect product production efficiency;

[0005] 2. The structure of receiving and sending out has a single role and cannot achieve the technical purpose of caching. Therefore, the adaptability is poor. Of course, if a cache is added between two adjacent processes, a cache device can be selected. This will inevitably lead to an increase in production costs, and once the line is broken, it will be more difficult to operate. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved buffering process with selectable buffering amount for continuous production of rubber products.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A buffering process with selectable buffering capacity for continuous production of rubber products, used for guiding and buffering two adjacent production processes, and the selectable buffering capacity equipment used includes a guiding unit and a buffering unit disposed between the two adjacent processes for guiding the rubber products, wherein a conveying roller is provided at the receiving end of each process, the guiding unit includes a first guiding roller group and a second guiding roller group, each of which is disposed on a process frame of each process and is rotated upward about a horizontal direction, wherein a gap is formed between the first guiding roller group and the second guiding roller group; the buffering unit includes a first buffering roller group and a second buffering roller group, each of which is disposed on the first guiding roller group and the second guiding roller group and synchronously supports the rubber product upward as the first guiding roller group and the second guiding roller group rotate. The process includes the following steps:

[0009] S 1. Transmission of the guiding unit

[0010] The rubber products from the previous process pass through the conveying roller, the first guide roller group, the second guide roller group, and the conveying roller in sequence to enter the next process;

[0011] S2, cache unit cache

[0012] The buffer includes a first buffer state and a second buffer state. In the first buffer state, the first guide roller group and the second guide roller group are respectively turned upward to open the notch, and the first buffer roller group and the second buffer roller group move synchronously therewith, and the formed buffer roller surface is located below or flush with the corresponding top guide roller. The rubber product spans above the notch and is lifted up for buffering and tensioned transmission through each roller;

[0013] When in the second cache state, on the basis of the first cache state, the first guide roller group and the second guide roller group are continued to be flipped upward to open the gap, and the first cache roller group and the second cache roller group move synchronously therewith, and the formed cache roller surface is located above the side of the corresponding top guide roller, and the rubber product falls from the gap between two adjacent processes for cache.

[0014] Preferably, the first guide roller group and the second guide roller group are symmetrically arranged about the notch and are synchronously flipped; the first buffer roller group and the second buffer roller group are symmetrically arranged about the notch and are synchronously supported.

[0015] According to a specific implementation and preferred aspect of the present invention, in S1, the guide rollers of the first guide roller group and the second guide roller group are arranged flush with each other, which greatly facilitates the horizontal transmission of the product and optimizes the transmission efficiency.

[0016] According to another specific embodiment and preferred aspect of the present invention, in step S2, the lifting amounts of the first and second buffer roller groups are the same and proportional to the tilting angles of the first and second guide roller groups. This ensures that products entering the notch are subjected to relatively uniform force, effectively coordinates tilting and lifting, and facilitates precise control of the buffer.

[0017] According to another specific embodiment and preferred aspect of the present invention, the first guide roller group includes a first guide frame, a first guide roller, and a first support member, and the second guide roller group includes a second guide frame, a second guide roller, and a second support member, wherein the first guide frame and the second guide frame are respectively connected to the process frames of two adjacent processes by pivoting along the length direction of the conveying roller, and the first guide frame and the second guide frame are separated from each other by a gap formed away from the end of the pivot; the first guide roller and the second guide roller are respectively spaced apart on the first guide frame and the second guide frame along the transmission direction of the rubber product, and the first support member and the second support member are respectively telescopically adjustable along their own length directions, and are respectively supported between the first guide frame and the process frame and between the second guide frame and the process frame on the corresponding side, so as to facilitate the implementation of flipping movement adjustment.

[0018] Preferably, the first guide frame includes first arms located on both sides, a first guide roller located between the two first arms, a first support member corresponding to the first arms and disposed below the first arms, and two ends of the first support member connected between the first guide frame and the process frame, with the connection points at the two ends of the first support member and the pivot point of the first guide frame forming a triangle. The second guide frame includes second arms located on both sides, the second guide roller located between the two second arms, a second support member corresponding to the second arms and disposed below the second arms, and two ends of the second support member connected between the second guide frame and the process frame, with the connection points at the two ends of the second support member and the pivot point of the second guide frame forming a triangle. Stable adjustment and support are achieved under changes in the length of the corresponding triangular supports and triangular arms.

[0019] According to another specific embodiment and preferred aspect of the present invention, the first buffer roller group includes a first lifting roller group and a first pressing roller group, and the second buffer roller group includes a second lifting roller group and a second pressing roller group. The first lifting roller group and the second lifting roller group lift the rubber product in the vertical direction, respectively. The first pressing roller group and the second pressing roller group are positioned near the conveying rollers of each process and press against the rubber product under their own weight. This one-pushing and one-pressing combination ensures that the rubber product adheres to the rollers for transportation and buffering.

[0020] According to another specific embodiment and preferred aspect of the present invention, the first and second lifting roller groups are respectively configured to be telescopically adjustable in a direction perpendicular to the first and second guide frames, with the respective telescopic amounts being proportional to the tilt angles of the first and second guide frames. This allows products to be buffered over the gap for a short distance, or they can be buffered from the gap to a location between two processes for stacking and caching, depending on actual needs.

[0021] Preferably, the optional buffer capacity device also includes an angle sensor arranged on the pivot and used to monitor the flipping angle of the first guide rack and the second guide rack, and a control processor connected to the first buffer roller group and the second buffer roller group, wherein the angle sensor is connected to the control processor.

[0022] Preferably, the first lifting roller group includes a first lifting roller horizontally arranged between the two first arms and parallel to the first guide roller, and a first telescopic cylinder respectively arranged on the first arm and driving the first lifting roller to move up and down in the up and down directions; the second lifting roller group includes a second lifting roller horizontally arranged between the two second arms and parallel to the second guide roller, and a second telescopic cylinder respectively arranged on the second arm and driving the second lifting roller to move up and down in the up and down directions.

[0023] Furthermore, the first pressing roller group includes a first pressing roller and a first lever arm for freely rotating the two ends of the first pressing roller and connecting them to the process frame; the second pressing roller group includes a second pressing roller and a second lever arm for freely rotating the two ends of the second pressing roller and connecting them to the process frame.

[0024] In addition, the guiding unit and the buffer unit form a transmission mode and a buffer mode. When in the transmission mode, the first guiding roller and the second guiding roller are arranged flush, and the first lifting roller and the second lifting roller are respectively located below the roller conveying surface formed by the first guiding roller and the second guiding roller; the buffer mode includes a first buffer state and a second buffer state. When in the first buffer state, the first guiding frame and the second guiding frame are respectively flipped upward to open the gap, the first lifting roller is located between the top and bottom first guiding rollers, and the second lifting roller is located between the top and bottom second guiding rollers, and the rubber product spans above the gap; when in the second buffer state, the gap becomes larger, and the first lifting roller and the second lifting roller are respectively raised to the side and above the top first guiding roller and the second guiding roller, and the rubber product falls from the gap into the space between two adjacent processes for buffering.

[0025] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0026] The present invention provides two selectable caching modes with different cache capacities through the synchronous collaboration of guidance and caching to meet the needs of different working conditions. It also further increases the guidance function, improves the adaptability of the equipment with selectable cache capacity, and has good practicality. In addition, the structure adopted is simple, easy to implement, and low in cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] like Figures 1 to 4 As shown, the buffering process with selectable buffering capacity for continuous production of rubber products in this embodiment is used to guide and buffer two adjacent production processes, and adopts a special selectable buffering capacity equipment, which includes a guiding unit 1 arranged between two adjacent processes for guiding rubber products, a buffering unit 2, and a temporary storage box 3 located between the two production processes. The rubber product takes the rubber strip D as an example, and the specific structure of the equipment adopted is as follows.

[0042] In this example, a conveying roller G is provided at the transfer end of each process.

[0043] The guiding unit 1 includes a first guiding roller group 11 and a second guiding roller group 12 which are respectively turned upward around the horizontal direction and arranged on the process frame J of each process, wherein a gap is formed between the first guiding roller group 11 and the second guiding roller group 12.

[0044] The buffer unit 2 includes a first buffer roller group 21 and a second buffer roller group 22 which are respectively arranged on the first guide roller group 11 and the second guide roller group 12 and synchronously support the rubber product upward as the first guide roller group 11 and the second guide roller group 12 turn over.

[0045] Specifically, the first guide roller group 11 and the second guide roller group 12 are symmetrically arranged about the notch; the first buffer roller group 21 and the second buffer roller group 22 are symmetrically arranged about the notch, which facilitates layout and assembly, as well as synchronous control.

[0046] The first guide roller assembly 11 includes a first guide frame 110 , a first guide roller 111 , and a first support member 112 .

[0047] The second guide roller assembly 12 includes a second guide frame 120 , a second guide roller 121 , and a second support member 122 .

[0048] The first guide frame 110 and the second guide frame 120 are respectively connected to the process frames J of two adjacent processes by pivoting along the length direction of the conveying roller G, and a gap is formed between the first guide frame 110 and the second guide frame 120 away from the pivot end.

[0049] The first guide roller 111 and the second guide roller 121 are respectively spaced apart and distributed on the first guide frame 110 and the second guide frame 120 along the transmission direction of the rubber product.

[0050] The first support rod 112 and the second support rod 122 are respectively adjusted to be telescopic along their own length direction, and are respectively supported between the first guide frame 110 and the process frame J, and between the second guide frame 120 and the process frame J on the corresponding side, so as to facilitate the implementation of the flipping movement adjustment.

[0051] The first guiding frame 110 includes first arms a located on both sides, a first guiding roller 111 located between the two first arms a, and a first support member 112 corresponding to the first arms a one-to-one and disposed below the first arms a.

[0052] In this example, both ends of the first support member 112 are connected between the first guide frame 110 and the process frame J, and the connection points of the two ends of the first support member 112 and the turning point of the first guide frame 110 form a triangle.

[0053] In this example, the first support member 112 is a double-ended telescopic cylinder.

[0054] The second guiding frame 120 includes second frame arms b located on both sides, and the second guiding roller 121 is located between the two second frame arms b.

[0055] The second support member 122 corresponds one-to-one with the second arm b and is positioned below the second arm b. The two ends of the second support member 122 are connected between the second guide frame 120 and the process frame J. The connection points of the second support member 122 and the pivot point of the second guide frame 120 form a triangle. This allows for stable adjustment and support despite changes in the length of the corresponding triangular support and triangular arm.

[0056] In this example, the second support member 122 is a double-ended telescopic cylinder.

[0057] The first buffer roller group 21 includes a first lifting roller group 210 and a first pressing roller group 211 , and the second buffer roller group 22 includes a second lifting roller group 220 and a second pressing roller group 221 .

[0058] The first lifting roller set 210 and the second lifting roller set 220 lift the rubber product along directions perpendicular to the first guiding frame 110 and the second guiding frame 120 , respectively.

[0059] The first pressing roller group 211 and the second pressing roller group 221 are close to the conveying roller G of each process and are placed on the rubber product by their own weight. The cooperation of one pressing and one pressing makes the rubber product fit the rollers for transmission and buffering.

[0060] The first and second lifting roller groups 210 and 220 are respectively adjustable in a direction perpendicular to the first and second guide frames 110 and 120, with the amount of expansion and contraction proportional to the tilt angle of the first and second guide frames 110 and 120. This allows products to be buffered over the gap for a short distance, or they can be buffered from the gap to a location between two processes for stacking and caching.

[0061] Specifically, the first lifting roller group 210 includes a first lifting roller d1 horizontally arranged between the two first arms a and parallel to the first guide roller 111, and a first telescopic cylinder d2 respectively arranged on the first arms a and driving the first lifting roller d1 to move up and down in a direction perpendicular to the first arms a. That is to say, combined with the projection of the main view, it can be seen that in the projection plane, the telescopic direction of the first telescopic cylinder d2 is perpendicular to the length direction of the first lifting roller d1.

[0062] The second lifting roller assembly 220 includes a second lifting roller d3, disposed transversely between the two second arms b and parallel to the second guide roller 121, and second telescopic cylinders d4, each mounted on the second arms b, that drive the second lifting roller d3 up and down. In other words, as can be seen from the projection of the front view, the extension and retraction directions of the second telescopic cylinders d4 are perpendicular to the longitudinal direction of the second lifting roller d3 within the projection plane.

[0063] The first pressing roller group 211 includes a first pressing roller y1 and a first lever arm y2 for freely rotatably connecting the two ends of the first pressing roller y1 to the process frame J.

[0064] The second pressing roller group 222 includes a second pressing roller y3 and a second lever arm y4 for connecting the two ends of the second pressing roller y3 to the process frame J for free rotation.

[0065] In addition, in order to facilitate the effective control of angles and telescopic displacements, in this example, the integrated guiding and caching device also includes an angle sensor arranged on a pivot and used to monitor the flipping angles of the first guiding frame 110 and the second guiding frame 120, and a control processor connected to the first cache roller group 21 and the second cache roller group 22, wherein the angle sensor is connected to the control processor.

[0066] At the same time, in this example, by providing a telescopic rod that can be horizontally extended at the lower part of the process frame J, the diagonal support stroke of the double-headed telescopic cylinder is further increased, the lifting height is increased, and the gap is expanded to facilitate caching.

[0067] Specifically, a first telescopic rod s1 capable of telescopically pushing the bottom of the first support member 112 and a second telescopic rod s2 capable of telescopically pushing the bottom of the second support member 122 are further provided at the lower part of the process frame J, wherein the first telescopic rod s1 and the second telescopic rod s2 respectively push the triangle to flip around the pivot.

[0068] In summary, the implementation process of this embodiment is as follows:

[0069] See again Figure 1 As shown, when in the transmission mode (transmission of the guiding unit in the above step S1), the first guiding roller 111 and the second guiding roller 121 are arranged flush, and the first lifting roller d1 and the second lifting roller d3 are respectively located below the roller conveying surface formed by the first guiding roller 111 and the second guiding roller 121. At this time, the rubber strip D passes smoothly through each roller and is transmitted between the two processes.

[0070] See again Figure 2 As shown (the first caching state of the above-mentioned step S2), the first guide frame 110 and the second guide frame 120 are respectively flipped upward to open the gap, the first lifting roller d1 is located between the top and bottom first guide rollers 111, and the second lifting roller d3 is located between the top and bottom second guide rollers 121, and the rubber strip D spans over the gap. Therefore, the rubber strip D can cover the gap and arch in the tensioning mode, meeting the caching and transmission needs of the rubber strip D with a small cache volume.

[0071] See again Figure 3 As shown (the second cache state of step S2 above), in Figure 2On the basis of this, if the gap continues to become larger, the first lifting roller d1 and the second lifting roller d3 rise to the upper side of the first guide roller 111 and the second guide roller 121 at the top respectively, and the rubber strip D falls from the gap to between the two adjacent processes for caching. Therefore, the rubber strip D can be cached from the gap to between the two adjacent processes through the high-position guidance of the cache roller, meeting the caching and transmission needs of the rubber strip D with a large cache volume. The structure is simple and the implementation is convenient.

[0072] Recombination Figure 4 As shown, in Figure 3 On the basis of this, the notch continues to be opened and the lifting roller rises, and the rubber strip D falls from the notch into the temporary storage box 3 below, so that the rubber strip D can be temporarily stored.

[0073] In summary, this embodiment has the following advantages:

[0074] 1. Through the synchronous collaboration of guidance and caching, two optional caching modes with different cache capacities are provided to meet the needs of different working conditions. In addition, the guidance function is further increased, and the adaptability of the equipment with selectable cache capacity is improved, which has better practicality.

[0075] 2. The stability of the overall structure is improved through triangular deformation and support. At the same time, with the assistance of the telescopic rod, the diagonal support stroke of the double-headed telescopic cylinder is further increased, the jacking height is increased, and the gap is expanded to facilitate caching.

[0076] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them. It does not limit the scope of protection of the present invention. Any equivalent changes or modifications made based on the spirit of the present invention should be included in the scope of protection of the present invention.
