[0001] This invention relates to the field of roll changing technology, and in particular to a roll changing device, roll changing system and roll changing method adapted to multi-roll synchronous roll changing. Background Technology

[0002] In industrial production, there are many situations where rollers are needed to perform different functions, such as rolling mill rollers, pinch rollers that provide power, and conveyor rollers in conveyor tracks. They are usually arranged in pairs or at equal intervals with fixed relative positions. There are also many roller systems with different diameters.

[0003] Currently, roller replacement is mainly achieved through manual operation with auxiliary tools. These tools are typically only compatible with one type of roller and can only replace one roller at a time, resulting in low efficiency and high labor intensity.

[0004] Therefore, it is essential to explore a multi-roller synchronous automatic roller changing tool that can replace multiple rollers at once and adapt to the replacement needs of rollers with diameter deviations. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a roller changing device, roller changing system and roller changing method adapted to multi-roll synchronous roller changing, so as to solve the problems of the prior art roller changing device being difficult to adapt to the synchronous replacement of rollers with roller diameter deviation and different roller diameters and the low replacement efficiency.

[0006] To achieve the above and other related objectives, the present invention provides a roll changing device adapted to multi-roll synchronous roll changing, comprising:

Each clamping component includes a fixed clamping block and a floating clamping block. The clamping channel is formed between the fixed clamping block and the floating clamping block of each pair of clamping components, and the floating clamping block is movable relative to the fixed clamping block to adaptively adjust the size of the clamping channel.

[0016] Optionally, the first driving mechanism further includes a pre-tightening elastic element, and an abutment portion is provided on the inner wall of the clamping channel. The two ends of the pre-tightening elastic element abut against the clamping assembly and the abutment portion respectively, and are adapted to drive the clamping assembly to move away from the clamping assembly on the opposite side.

[0017] Optionally, the fixing clamp has a first inclined surface located outside the mounting base, and the transmission member has a second inclined surface that can fit against the first inclined surface. The first driving member drives the second inclined surface of the transmission member to slide relative to the first inclined surface, thereby pushing the fixing clamp to move.

[0018] Optionally, the mounting support assembly further includes a mounting frame, the mounting base is mounted on the mounting frame, one end of the mounting base on which the fixing clamp is mounted extends into the mounting frame, and the gap between the first inclined surface and the inner sidewall of the mounting frame forms a guide channel, the transmission member is mounted in the mounting frame and moves along the guide channel to push the fixing clamp.

[0046] Before describing the embodiments of the present invention in detail, the application environment of the present invention will be described first. The technology of the present invention is mainly applied to the field of metallurgical technology, especially to the roll changing technology of metallurgical equipment. The present invention solves the problems of low roll changing efficiency and difficulty in adapting to the synchronous replacement of multiple rolls with diameter deviations in traditional roll changing devices.

[0047] See Figures 1 to 4 , Figure 9 and Figure 10 In some alternative embodiments, this application provides a roll changing device adapted to multi-roll synchronous roll changing, including a mounting support assembly, a clamping unit 2, and a first drive mechanism. In addition to the above-mentioned components, the roll changing device adapted to multi-roll synchronous roll changing may also include a fixed base 5 and a second drive mechanism.

[0048] Optionally, the mounting support assembly includes a mounting base 11, which has a clamping channel 111 suitable for the roller 9 to be inserted into the mounting base 11 axially; the clamping unit 2 includes at least a pair of clamping components 21 arranged opposite each other, and at least two parallel clamping channels 22 are formed between the clamping components 21 arranged opposite each other. The clamping components 21 are movably mounted on the mounting base 11 and can at least partially extend into or out of the clamping channel 111. The clamping channels 22 are correspondingly arranged with the roller 9, and multiple clamping channels 22 can clamp multiple rollers 9. Partial structures of each pair of opposing clamping components 21 can float to adjust the size of the clamping channel 22, thereby enabling multiple clamping channels 22 to synchronously clamp the corresponding rollers 9. Specifically, the clamping components 21 include fixed clamping blocks 211 and floating clamping blocks 212. A clamping channel 22 is formed between the fixed clamping blocks 211 and floating clamping blocks 212 of each pair of clamping components 21, and the floating clamping blocks 212 can move relative to the fixed clamping blocks 211 to adaptively adjust the size of the clamping channel 22. A first driving mechanism drives the opposing clamping components 21 to move closer together to clamp the rollers 9 or move away to release the rollers 9. Further, each pair of clamping components includes two symmetrically arranged clamping components 21, which can be arranged along the Z-direction. Further, the clamping channel 111 can be a rectangular channel, but is not limited to a rectangle; it can also be circular or other shapes, suitable for the rollers 9 to pass through.

[0049] Optionally, the clamping roller diameters of two adjacent clamping channels 22 can be the same or different.

[0050] Optionally, each clamping channel 22 is provided with at least two clamping positions 221 along its extension direction. The clamping roller diameter of each clamping position 221 is different and decreases sequentially along the direction in which the roller 9 extends into the clamping channel 22. That is, when the two clamping components 21 are at the same relative distance, the clamping roller diameter of the clamping position 221 closer to the entrance end of the clamping channel 22 is larger than that of the clamping position 221 farther from the entrance end of the clamping channel 22. In other words, when the roller 9 extends into the clamping channel 22, it first passes through the clamping position 221 with the larger clamping roller diameter and then passes through the clamping position 221 with the smaller clamping roller diameter, so as to adapt to clamping rollers 9 with different roller diameters. For example, the clamping position 221 with a larger clamping roller diameter can clamp a large roller 91, and the clamping position 221 with a smaller clamping roller diameter can clamp a small roller 92. With this structural design, it can adapt to clamping rollers 9 with different roller diameters without changing parts. It has a wide range of applications, higher versatility, simple structure, and helps to reduce costs. In this application, the extension direction of the clamping channel 22, the axial direction of the roller 9, the direction in which the roller 9 extends into or exits the clamping channel 22, and the arrangement direction of the multiple clamping positions 221 in the same clamping channel 22 are all the same, namely the X direction in the figure.

[0051] The roller changing device adapted to multi-roll synchronous roller changing in the above embodiment can not only realize the synchronous replacement of multiple rollers 9, but also allow part of the structure of the clamping component 21 to float so as to finely adjust the size of the clamping channel 22, thereby adapting to the synchronous replacement of multiple rollers 9 with roller diameter deviation, making the clamping of rollers 9 more stable and reliable, and improving the roller changing efficiency.

[0052] See Figures 1 to 10 In some optional embodiments, the fixed clamping block 211 is provided with at least two side-by-side first clamping portions 2111, and the floating clamping block 212 is movably mounted on the fixed clamping block 211 and located between two adjacent first clamping portions 2111. The floating clamping block 212 is provided with a second clamping portion 2121 corresponding to the first clamping portion 2111. The second clamping portion 2121 cooperates with the corresponding first clamping portion 2111 to form a clamping portion. The clamping portions of each pair of oppositely arranged clamping components 21 cooperate to form at least two clamping channels 22.

[0053] Optionally, the clamping roller diameters of the two clamping channels 22 sharing the same floating clamping block 212 can be the same or different, or in other words, the clamping roller diameters of the side-by-side clamping positions 221 can be the same or different.

[0054] Optionally, the fixed clamping block 211 is provided with a mounting groove 2113, and the floating clamping block 212 is movably mounted in the mounting groove 2113 and can move along the parallel direction of the first clamping parts 2111; wherein, multiple first clamping parts 2111 can be distributed side by side along the Y direction. Further, the floating clamping block 212 has a protrusion that cooperates with the mounting groove 2113. The protrusion is inserted into the mounting groove 2113 to restrict the floating clamping block 212 from moving away from the fixed clamping block 211 along the Z direction. A floating gap is left between the protrusion and the mounting groove 2113 in the Y direction, allowing the floating clamping block 212 to move relative to the fixed clamping block 211 along the Y direction within a certain range, thereby accommodating multiple rollers 9 with roller diameter deviations to be clamped synchronously, thus achieving synchronous multi-roller replacement. Specifically, the mounting groove 2113 can be a square groove.

[0055] Optionally, the first clamping part 2111 includes at least two first step surfaces 2112 distributed in a stepped manner along the direction in which the roller 9 extends into the clamping channel 22, and the second clamping part 2121 includes a second step surface 2122 corresponding to the first step surface 2112. The second step surface 2122 and the first step surface 2112 cooperate to form a V-shaped clamping surface. Each pair of oppositely arranged V-shaped clamping surfaces constitutes a clamping position 221. The structure is simple and the clamping is convenient and reliable. It is understood that the shape of the clamping surface forming the clamping position 221 is not limited to the V-shape mentioned above. Specifically, the first step surface 2112 at the entrance end away from the clamping channel 22 protrudes from the first step surface 2112 at the entrance end near the clamping channel 22, and the second step surface 2122 at the entrance end away from the clamping channel 22 protrudes from the second step surface 2122 at the entrance end near the clamping channel 22. That is, when the relative distance between the two clamping components 21 is the same, the roller diameter of the roller 9 suitable for clamping by the first step surface 2112 and the second step surface 2122 at the entrance end of the clamping channel 22 is smaller than the roller diameter of the roller 9 suitable for clamping by the first step surface 2112 and the second step surface 2122 at the entrance end of the clamping channel 22. Furthermore, the opening angle of each clamping position 221 in the same clamping channel 22 can be the same; that is, the first step surfaces 2112 of the same clamping channel 22 can be arranged in parallel, and the second step surfaces 2122 of the same clamping channel 22 can be arranged in parallel, simplifying the molding and manufacturing process and making clamping more convenient.

[0056] Optionally, the mounting base 11 is provided with a mounting hole 112, which penetrates the side wall of the mounting base 11 and communicates with the clamping channel 111. The clamping assembly 21 is movably mounted in the mounting hole 112 so that the clamping assembly 21 can move to clamp or release the roller 9. Furthermore, the fixed clamping block 211 of the clamping assembly 21 is movably mounted in the mounting hole 112, and the movement of the fixed clamping block 211 causes the floating clamping block 212 to move together.

[0057] The roller changing device adapted to multi-roll synchronous roller changing in the above embodiment has a simple structure, compact layout, convenient manufacturing, and wide applicability. It can not only adapt to the clamping of rollers 9 with different diameters, but also overcome roller diameter deviation to achieve synchronous replacement of rollers 9 with roller diameter deviation, thereby improving replacement efficiency.

[0058] See Figures 1 to 10 In some alternative embodiments, the first drive mechanism includes a transmission member 32 and a first drive member 31. The first drive member 31 drives the clamping assembly 21 to move closer to the clamping assembly 21 on the opposite side through the transmission member 32.

[0059] Optionally, the first driving mechanism further includes a pre-tightening elastic element 33. An abutment portion 113 is provided on the inner wall of the clamping channel 111. Both ends of the pre-tightening elastic element 33 abut against the clamping assembly 21 and the abutment portion 113 respectively, and are adapted to drive the clamping assembly 21 to move away from the opposite clamping assembly 21. Further, a top plate 34 is connected to the end of the elastic pre-tightening element facing the abutment portion 113 by screws. The top plate 34 elastically abuts against the abutment portion 113. Two sets of pre-tightening elastic element assemblies are arranged along the Y direction in the same clamping assembly 21. The clamping channel 22 is located between the two sets of pre-tightening elastic element assemblies. Each set of pre-tightening elastic element assemblies includes two pre-tightening elastic elements 33 distributed along the X direction. Each pre-tightening elastic element 33 in the same set is connected to the same top plate 34. Pre-tightening elastic elements 33 are installed at the four corner positions of the clamping assembly 21. The layout is simple and compact, and the elastic pre-tightening force is uniform and stable. It is understood that the number of pre-tightening elastic elements 33 is not limited to the number listed. Specifically, the pre-tightening elastic element 33 can be a spring. When the clamping assembly 21 is installed in the mounting hole 112, the spring is in a compressed state and can provide elastic pre-tightening force. When the transmission element 32 is withdrawing, the elastic pre-tightening force can push the clamping assembly 21 to gradually extend out of the mounting hole 112 to increase the distance between it and the opposite clamping assembly 21.

[0060] Optionally, the fixed clamping block 211 has a first inclined surface 213 located outside the mounting base 11, and the transmission member 32 has a second inclined surface 321 that can fit against the first inclined surface 213. The first driving member 31 drives the second inclined surface 321 of the transmission member 32 to slide relative to the first inclined surface 213, thereby pushing the fixed clamping block 211 to move. The slope of the second inclined surface 321 matches the slope of the first inclined surface 213. The second inclined surface 321 and the first inclined surface 213 fit against each other and can slide relative to each other, pushing the clamping assembly 21 closer to the opposite clamping assembly 21 to clamp the roller 9.

[0061] Optionally, the mounting support assembly also includes a mounting frame 12, a mounting base 11 mounted on the mounting frame 12, one end of the mounting base 11 with a fixing block 211 extending into the mounting frame 12, and the gap between the first inclined surface 213 of the fixing block 211 and the inner sidewall of the mounting frame 12 forms a guide channel, and the transmission member 32 is mounted in the mounting frame 12 and moves along the guide channel to push the fixing block 211. Furthermore, the transmission component 32 is anti-rotationally mounted within the mounting frame 12. The first driving component 31 can be a rotary motor, rotary cylinder, rotary hydraulic cylinder, or other power component capable of providing rotational power. The output end of the first driving component 31 is connected to a screw 35. The transmission component 32 is provided with a threaded hole 322 that is threadedly connected to the screw 35. The screw 35 extends into the threaded hole 322. The rotation of the first driving component 31 drives the transmission component 32 to move linearly, thereby pushing the clamping assembly 21 to move closer to the opposite clamping assembly 21. It can be understood that the interface between the transmission component 32 and the first driving component 31 is not limited to the threaded hole 322 mentioned above. It can be configured with different structures according to the first driving component 31. For example, it can be a hinged shaft hole that cooperates with a rotary cylinder or rotary hydraulic cylinder. The mounting frame 12 can be a square frame, and the transmission component 32 can be a U-shaped frame. The bottom of the U-shaped frame has a protrusion on the side facing away from its opening, and a threaded hole 322 is provided on the protrusion. The inner sidewall of the U-shaped frame is partially inclined to form a second inclined surface 321, and the outer sidewall of the U-shaped frame is flat and can fit against the inner sidewall of the square frame, so that the transmission component 32 can only move within the mounting frame 12 and cannot rotate. The mounting base 11 extends into the square frame from the front end and is connected to the front end wall of the square frame by screws. An end plate is installed at the rear end of the square frame. The first driving component 31 is located outside the square frame and is connected to the end plate to be fixed on the end plate and can move with the square frame. The screw 35 connected to the first driving component 31 passes through the end plate and extends into the square frame to be threadedly connected to the transmission component 32. Specifically, when it is necessary to clamp the roller 9, the first driving member 31 rotates and drives the transmission member 32 to move closer to the front end of the square frame, so that the two clamping components 21 arranged opposite to each other move closer to clamp the roller 9; when it is necessary to release the roller 9, the first driving member 31 rotates and drives the transmission member 32 to move closer to the rear end of the square frame, that is, the transmission member 32 gradually exits the guide channel, and under the action of the pre-tightening elastic member 33, the two clamping components 21 arranged opposite to each other move away from each other to release the roller 9.

[0062] Optionally, the outer wall of the mounting base 11 has a third inclined surface 114, and the mounting hole 112 passes through the third inclined surface 114. The slope of the third inclined surface 114, the slope of the first inclined surface 213, and the slope of the second inclined surface 321 are all the same, which is conducive to the smooth and stable movement of the transmission component 32 and is not easy to jam.

[0063] The roller changing device adapted to multi-roller synchronous roller changing in the above embodiment has a simple structure and compact layout of the first drive mechanism, which can flexibly and stably drive the clamping assembly 21 to move in opposite directions or in opposite directions, and is not easy to jam, thus ensuring the reliability of the clamping roller 9 and the releasing roller 9.

[0064] See Figure 1 , Figure 2 and Figure 13 In some optional embodiments, the roller changing device adapted to multi-roll synchronous roller changing further includes a fixed base 5 and a second drive mechanism. The mounting frame 12 is rotatably mounted on the fixed base 5. The second drive mechanism drives the mounting frame 12 to rotate, thereby causing the side-by-side clamping channels 22 to flip and adjust their positions in the vertical direction, thus adapting to synchronously clamping rollers 9 arranged in different directions. For example, some pairs of rollers 9 are arranged along the X direction, and some pairs of rollers 9 are arranged along the Y direction. The second drive mechanism drives the mounting frame 12 to rotate, which in turn drives the clamping unit 2 to rotate synchronously, so that the side-by-side clamping channels 22 can switch between the Y and Z directions, thereby adapting to clamping rollers 9 arranged in different directions.

[0065] Optionally, the second drive mechanism includes a second drive component 41, an adapter seat, and a bearing 42. The output end of the second drive component 41 is connected to the adapter seat, which is rotatably mounted in the fixed seat 5 via the bearing 42. The adapter seat is connected to the end plate of the mounting frame 12. The rotation of the second drive component 41 drives the mounting frame 12 to rotate. Further, the second drive component 41 can be a rotary motor, a rotary cylinder, a rotary hydraulic cylinder, or other power components capable of providing rotational power. Specifically, the second drive component 41 is a rotary motor with an editor to enable precise rotation, thereby accommodating roller 9 changes in different arrangement directions.

[0066] The roller changing device adapted to multi-roll synchronous roller changing in the above embodiment drives the mounting support assembly, clamping unit 2 and the first drive mechanism to rotate synchronously to adapt to the picking and placing of rollers 9 with different arrangement directions, thus making the roller changing application range wider.

[0067] See Figure 12 and Figure 13 In some optional embodiments, this application also provides a roll changing system, including a roll changing device adapted to multi-roll synchronous roll changing as in any of the above embodiments, and further including a lifting device 7 and a traveling device 6. The lifting device 7 is mounted on the traveling device 6 and is connected to the roll changing device adapted to multi-roll synchronous roll changing, and drives the roll changing device adapted to multi-roll synchronous roll changing to rise and fall. The lifting device 7 is mounted on the traveling device 6 and the traveling device 6 can drive the lifting device 7 to move, thereby driving the roll changing device adapted to multi-roll synchronous roll changing to move. Through the cooperation of the traveling device 6 and the lifting device 7, the roll changing device adapted to multi-roll synchronous roll changing is driven to move and rise and fall to align with the roll 9 to achieve the clamping of the roll 9.

[0068] Optionally, the traveling device 6 includes a vehicle body 61 with wheels mounted on its bottom. A lifting device 7 and a translation mechanism 62 are mounted on the vehicle body 61. A roller changing device adapted for multi-roller synchronous roller changing is mounted on the lifting device 7, which adjusts its height along the Z-axis. The lifting device 7 can be mounted on the translation mechanism 62, which moves the lifting device 7 along the Y-axis. The vehicle body 61 can move along the X-axis, thus enabling movement in all directions. This allows the roller changing device adapted for multi-roller synchronous roller changing to accurately align with the rollers 9 and to pick up and place the rollers 9. It is understood that the movement direction of the vehicle body 61 is not limited to the X-axis.

[0069] Optionally, the roller changing system also includes a storage rack 8, which has multiple storage stations for storing rollers 9 of different diameters. For example, it can store large rollers 91 with larger diameters or small rollers 92 with smaller diameters.

[0070] The roller changing system described in the above embodiment is suitable for multi-roll synchronous roller changing devices. The roller changing device is simple and convenient to move and lift, which is conducive to quickly picking up, placing and transferring rollers 9 and improving roller changing efficiency.

The roller changing operation is simple and convenient, with low difficulty, which is beneficial to improving the roller changing efficiency.

[0072] Specifically, firstly, the vehicle body 61 moves along the X-axis towards the storage rack 8 until it reaches a preset position, so that the roller changing device adapted for multi-roller synchronous roller changing is initially positioned in the X-axis. Then, the lifting device 7 and the translation mechanism 62 drive the roller changing device adapted for multi-roller synchronous roller changing to move in the Z and Y directions respectively to the position of the roller 9 to be replaced; if the two rollers 9 in a pair are arranged horizontally along the Y-axis, the encoder-equipped rotary motor drives the mounting frame 12 to rotate to a horizontal position; if the two rollers 9 in a pair are arranged vertically along the Z-axis, the encoder-equipped rotary motor drives the mounting frame 12 to rotate to a vertical position. Next, the vehicle body 61 continues to move forward as a whole until multiple rollers 9 side by side enter the clamping channel 22 of the clamping unit 2. Next, the first driving member 31 drives the transmission member 32 to move forward until the two clamping components 21 move towards each other and synchronously clamp multiple rollers 9 arranged side by side. Then, the vehicle body 61 moves to the installation position of the roller 9 as a whole. Next, the first driving component 31 drives the transmission component 32 to move backward, and the pre-tightening elastic component 33 pushes the two clamping components 21 to move away from each other and simultaneously release the multiple side-by-side rollers 9. The vehicle body 61 moves to the initial position as a whole, completing the replacement operation of the rollers 9.

[0073] The roller changing method described in the above embodiments is simple in its steps, easy to operate, and has low difficulty in changing rollers. It facilitates automated roller changing, which helps to improve roller changing efficiency and reduce production costs.

[0074] The present invention relates to a roller changing device, roller changing system, and roller changing method adapted to multi-roll synchronous roller changing. The clamping unit 2 has multiple clamping channels 22, each clamping channel 22 having multiple clamping positions 221 with different roller diameters, which can accommodate the picking and placing of rollers 9 with different roller diameters, has a wide range of applications, does not require frequent replacement of parts, reduces costs, and improves roller changing efficiency. In addition, the clamping unit 2 includes a fixed clamping block 211 and a floating clamping block 212. The floating clamping block 212 can be adjusted relative to the fixed clamping block 211, so that the clamping channel 22 has a floating adjustment function to adaptively change the size of the clamping channel 22, so as to achieve synchronous clamping of multiple rollers 9 with roller diameter deviations, improve clamping adaptability, reduce the requirements for roller diameter accuracy of rollers 9, reduce the difficulty of roller changing, and have stronger roller changing ability and higher roller changing efficiency.
