[0026] Example Please refer to the following: Figure 1 and Figure 2 , Figure 1 The diagram shown is a structural schematic of the empty roll buffer device 100 provided in this embodiment from one perspective. Figure 2 The diagram shown is a structural schematic of the empty roll buffer device 100 from another perspective.

[0027] The empty roll buffer device 100 provided in this embodiment includes a device body 110, a feeding mechanism 120, a conveying mechanism 130, a detection mechanism 150, and a cleaning mechanism 140. The feeding mechanism 120, the conveying mechanism 130, the detection mechanism 150, and the cleaning mechanism 140 are all disposed on the device body 110. The feeding mechanism 120 is used to feed empty rolls 200 and transfer the empty rolls 200 to the conveying mechanism 130. The conveying mechanism 130 is used to transport the empty rolls 200 to the detection mechanism 150 and the cleaning mechanism 140 along a first direction. The detection mechanism 150 is located upstream of the cleaning mechanism 140 and is used to detect the straightness of the empty rolls 200 on the conveying mechanism 130. The cleaning mechanism 140 is used to clean the empty rolls 200 and store the cleaned empty rolls 200 in the storage part 111 on the device body 110.

[0028] In this embodiment, the feeding mechanism 120, the detection mechanism 150, and the cleaning mechanism 140 are arranged sequentially along the first direction. In practical applications, the empty roll 200 after unwinding is placed in the feeding mechanism 120. The feeding mechanism 120 transfers the empty roll 200 to the conveying mechanism 130. The conveying mechanism 130 conveys the empty roll 200 along the first direction. When the empty roll 200 passes the detection mechanism 150, the detection mechanism 150 detects the straightness of the empty roll 200. When the empty roll 200 reaches the cleaning mechanism 140, the cleaning mechanism 140 cleans the empty roll 200.

[0029] As can be seen, the empty roll buffer device 100 provided in this embodiment, compared with the traditional roll buffer rack, can also perform straightness detection and automatic cleaning on the empty roll 200, which can improve cleaning efficiency and cleaning effect, and screen out the empty rolls 200 that do not meet the straightness requirements, so as to prevent the deformed empty rolls 200 from continuing to be wound and unwound, which would affect the quality of the product.

[0030] Please refer to the following: Figure 3 , Figure 3 The diagram shown is a structural schematic of the feeding mechanism 120.

[0031] The feeding mechanism 120 includes a base plate 121, a third driving member 122, a fourth driving member 123, and a bearing assembly 124. The third driving member 122 is connected to the fourth driving member 123 and is used to drive the fourth driving member 123 to move in a first direction. The fourth driving member 123 is connected to the base plate 121 and is used to drive the base plate 121 to move in a vertical direction. The bearing assembly 124 is disposed on the base plate 121 and is used to support the empty drum 200.

[0032] The support assembly 124 includes two support plates 1241 and two adjusting drive members 1242. The two support plates 1241 are slidably erected on the base plate 121 and are arranged opposite to each other in the second direction. The two support plates 1241 are used to jointly support the empty drum 200. The two adjusting drive members 1242 are both disposed on the base plate 121 and connected to the two support plates 1241 respectively, and are used to drive the two support plates 1241 to move in the second direction to adjust the distance between the two support plates 1241.

[0033] In this embodiment, the first direction and the second direction are perpendicular to each other and both are parallel to the horizontal plane. The base plate 121 is parallel to the horizontal plane, and both support plates 1241 are slidably engaged with the base plate 121. Specifically, both ends of the base plate 121 in the second direction are provided with vertically penetrating grooves. The two grooves extend in the second direction, and the two support plates 1241 pass through the two grooves respectively and are slidably engaged with the two grooves.

[0034] Both adjusting drive components 1242 are disposed on the lower surface of the base plate 121 and are respectively connected to the two support plates 1241 for transmission. The two adjusting drive components 1242 can drive the two support plates 1241 to slide in the two slide grooves respectively, thereby adjusting the distance between the two support plates 1241 in the second direction. In this embodiment, both adjusting drive components 1242 are lead screw motors, and the lead screw of any adjusting drive component 1242 extends in the second direction and is threadedly engaged with the corresponding support plate 1241.

[0035] Each of the two trays 1241 has a V-shaped groove at its top for receiving empty rolls 200. When the empty rolls 200 are loaded, at least both ends of the empty rolls 200 are partially embedded in the two V-shaped grooves. In this embodiment, photoelectric detection elements 125 for detecting the presence of empty rolls 200 are provided in the two V-shaped grooves. The two photoelectric detection elements 125 are electrically connected to the controller of the empty roll buffer device 100. Furthermore, the upper surface of the base plate 121 is also provided with photoelectric detection elements 125 electrically connected to the controller. When the signals of the three photoelectric detection elements 125 are triggered, the controller determines that the empty rolls 200 have been loaded.

[0036] In this embodiment, a first vision camera 126 for identifying the size of the empty roll 200 is also provided on the upper surface of the base plate 121. The first vision camera 126 is electrically connected to the controller. In practical applications, after the first vision camera 126 identifies the size of the empty roll 200, the controller controls two adjusting drive members 1242 to drive the two support plates 1241 to move, adjusting the distance between the two support plates 1241 in the second direction to accommodate the current empty roll 200.

[0037] Please refer to the following: Figure 4 , Figure 4 The diagram shown is a structural schematic of the conveying mechanism 130.

[0038] In this embodiment, the conveying mechanism 130 includes two conveyor belts 131 arranged side by side in a second direction, and a housing 133 for receiving the two conveyor belts 131. Each conveyor belt 131 is equipped with a servo motor 134 and a pulley 135. Multiple stops 132 are spaced apart on the surface of each of the two conveyor belts 131. It is understood that for any conveyor belt 131, the gap between any two adjacent stops 132 on its surface is used to receive one end of an empty drum 200.

[0039] In practical applications, the feeding mechanism 120 is located at the end of the two conveyor belts 131 away from the cleaning mechanism 140 in the first direction, and the base plate 121 is located between the two conveyor belts 131. When feeding the empty roll 200, the empty roll 200 is first placed in the two V-shaped grooves at the top of the two pallets 1241. Then, the fourth drive member 123 drives the base plate 121 to rise until the empty roll 200 is above the two conveyor belts 131. Then, the third drive member 122 drives the base plate 121 to move in the first direction, moving the empty roll 200 from one end of the two conveyor belts 131 to above the two conveyor belts 131. Then, the fourth drive member 123 drives the base plate 121 to descend, moving the empty roll 200 down until both ends of the empty roll 200 are supported by the two conveyor belts 131 respectively, thereby completing the transfer of the empty roll 200 to the conveying mechanism 130.

[0040] In this embodiment, the third driving component 122 is a cylinder, fixed to the main body 110 of the device, and its telescopic end extends in the first direction and is connected to the fourth driving component 123 through the connecting bracket 127. The fourth driving component 123 is also a cylinder, and its telescopic end extends in the vertical direction and is connected to the base plate 121. In order to ensure a smooth transfer process, in this embodiment, the main body 110 of the device is also provided with a first slide rail 114 extending in the first direction, and the connecting bracket 127 slides in cooperation with the first slide rail 114.

[0041] In this embodiment, the cleaning mechanism 140 includes a pickup component and a cleaning component 141. The pickup component is used to pick up the empty roll 200 on the conveying mechanism 130 and drive the empty roll 200 to rotate. The cleaning component 141 is used to abut against the outer wall of the empty roll 200 so that the empty roll 200 completes cleaning during rotation.

[0042] Specifically, the cleaning component 141 is located above the storage section 111, and the pickup component is also used to release the empty roll 200 after cleaning, so that the empty roll 200 falls downward into the storage section 111, with the first direction forming an angle with the vertical direction.

[0043] Please refer to the following: Figure 5 , Figure 5 The diagram shown is a structural schematic of the cleaning component 141.

[0044] In this embodiment, the cleaning component 141 includes a wiping member 1411, a mounting member 1412, and a wiping drive member 1413. The wiping member 1411 is disposed on the mounting member 1412, and the wiping drive member 1413 is disposed on the device body 110 and connected to the mounting member 1412. The wiping drive member 1413 is used to drive the mounting member 1412 to move until the wiping member 1411 abuts against the outer wall of the empty roll 200.

[0045] Preferably, in this embodiment, the wiping member 1411 is a felt, which is attached to the mounting member 1412. The wiping drive member 1413 is actually a cylinder, which is fixed to the device body 110, and its telescopic end extends in the first direction and is connected to the mounting member 1412. The mounting member 1412 has a concave arc surface 1417 on the side opposite to the wiping drive member 1413, and the wiping member 1411 is attached to the concave arc surface 1417.

[0046] In practical applications, as the pickup component drives the empty drum 200 to rotate, the wiping drive component 1413 drives the wiping component 1411 to adhere to the side wall of the empty drum 200, thus completing the cleaning of the side wall of the empty drum 200 during the rotation of the empty drum 200.

[0047] In this embodiment, the cleaning assembly 141 further includes a first distance sensor 1414, which is disposed on the mounting member 1412 and is used to detect the distance between the wiping member 1411 and the empty roll 200. In fact, the first distance sensor 1414 is also electrically connected to the controller. The controller controls the extension and retraction stroke of the wiping drive member 1413 based on the detection data from the first distance sensor 1414, preventing the wiping drive member 1413 from applying excessive pressure to the empty roll 200 through the mounting member 1412 and the wiping member 1411.

[0048] The cleaning assembly 141 also includes a liquid supply module 1415, which is connected to the wiping member 1411 and is used to provide wiping liquid to wet the wiping member 1411. Preferably, in this embodiment, the wiping liquid provided by the liquid supply module 1415 to the wiping member 1411 is alcohol.

[0049] Furthermore, the cleaning assembly 141 also includes a drying module 1416, which is disposed on the mounting member 1412 and is used to dry the cleaned empty roll 200. Preferably, in this embodiment, the drying module 1416 is provided with a compressed air hole for blowing a high-speed airflow onto the cleaned empty roll 200 to quickly dry the empty roll 200.

[0050] In this embodiment, the picking component includes two clamping modules 142, please refer to the following: Figure 6 and Figure 7 , Figure 6 The diagram shown is a structural schematic of the clamping module 142. Figure 7 The image shown is a perspective view of the clamping module 142.

[0051] Both clamping modules 142 are movably mounted on the main body 110 of the device and are located on both sides of the conveying mechanism 130 in the second direction. The two clamping modules 142 are used to clamp the empty drum 200 together and drive the empty drum 200 to move and rotate.

[0052] Specifically, the clamping module 142 includes a mounting body 1421, and a top cone 1422, a clamping drive 1423, and a rotation drive 1424 disposed on the mounting body 1421. The mounting body 1421 is movably disposed on the device body 110. The clamping drive 1423 is used to drive the top cone 1422 to move relative to the mounting body 1421 in a second direction to clamp or release the empty drum 200. The rotation drive 1424 is used to drive the top cone 1422 to rotate, thereby driving the empty drum 200 to rotate.

[0053] The clamping module 142 also includes a first driving member 1425 and a second driving member 1426. The first driving member 1425 is disposed on the device body 110 and connected to the second driving member 1426, and is used to drive the second driving member 1426 to move in a first direction. The second driving member 1426 is connected to the mounting body 1421 and is used to drive the mounting body 1421 to move in the vertical direction.

[0054] Preferably, in this embodiment, the first driving member 1425 is a cylinder, whose telescopic end extends in the first direction and connects to the second driving member 1426, enabling the second driving member 1426 to move in the first direction, thereby driving the empty drum 200 to move in the first direction. The second driving member 1426 is a lead screw motor, whose lead screw extends in the vertical direction and is connected to the mounting body 1421 through a slider, so as to drive the mounting body 1421 to move in the vertical direction.

[0055] In practical applications, the two clamping modules 142 adjust the position of the mounting body 1421 in the first direction and the vertical direction through the coordinated action of the first driving member 1425 and the second driving member 1426. Under the coordinated action of the first driving member 1425 and the second driving member 1426, when the top cones 1422 of the two clamping modules 142 are aligned with the two ends of the empty drum 200 on the conveying mechanism 130, the clamping driving member 1423 drives the top cones 1422 to extend relative to the mounting body 1421 in the second direction, so as to clamp and fix the empty drum 200 together with the other top cone 1422.

[0056] With the empty drum 200 clamped by the two top cones 1422, the first drive member 1425 and the second drive member 1426 work together again to move the empty drum 200 away from the conveying mechanism 130 and above the storage section 111 of the main body 110. Then, the wiping drive member 1413 drives the mounting member 1412 to move until the wiping member 1411 on the mounting member 1412 is in contact with the side wall of the empty drum 200. Afterwards, the rotation drive member 1424 drives the top cones 1422 to rotate, thereby rotating the empty drum 200 so that the wiping member 1411 cleans the surface of the empty drum 200.

[0057] After cleaning, the drying module 1416 dries the surface of the empty roll 200. The wiping drive 1413 drives the mounting component 1412 to move, causing the wiping component 1411 to separate from the empty roll 200. Then, the clamping drive 1423 drives the top cone 1422 to retract relative to the mounting body 1421 in the second direction to release the empty roll 200, causing the empty roll 200 to fall into the lower storage part 111.

[0058] In this embodiment, a second vision camera 1427 is provided on the top cone 1422 to detect the position of the empty drum 200 in real time, so as to ensure that the top cone 1422 is aligned with the end of the empty drum 200. Furthermore, an expansion block 1428 is provided on the side wall of the top cone 1422. When the top cone 1422 extends into the end of the empty drum 200, the expansion block 1428 on the side wall of the top cone 1422 pops out and presses against the empty drum 200, thereby locking and fixing the empty drum 200.

[0059] Please refer to the following: Figure 8 and Figure 9 , Figure 8 The diagram shown is a schematic representation of the detection structure. Figure 9 As shown Figure 8 An enlarged schematic diagram of region A in the middle.

[0060] The detection mechanism 150 is located between the feeding mechanism 120 and the cleaning mechanism 140, and is used to detect the straightness of the empty rolls 200 on the conveying mechanism 130. The empty roll buffer device 100 provided in this embodiment also includes a rejection mechanism 160. The device body 110 has a defective product storage section 112. The rejection mechanism 160 is used to transfer empty rolls 200 with unqualified straightness to the defective product storage section 112.

[0061] The testing mechanism 150 includes a second slide rail 151, a fifth drive member 152, a clamp 153, a dial indicator 154, and a testing drive member 155. The fifth drive member 152 is mounted on the main body 110 and connected to the second slide rail 151, and is used to drive the second slide rail 151 to move in the vertical direction. The clamp 153 is slidably mounted on the second slide rail 151. The testing drive member 155 is mounted on the second slide rail 151 and connected to the clamp 153, and is used to drive the clamp 153 to slide in the second direction. The dial indicator 154 is mounted on the clamp 153 and is used to slide on the outer wall of the empty drum 200 under the drive of the clamp 153.

[0062] During the conveying process of the empty drum 200 by the conveying mechanism 130, the detection mechanism 150 is positioned below the empty drum 200. When the empty drum 200 moves above the conveying mechanism 130, the fifth drive member 152 drives the second slide rail 151 to rise until the roller at the detection end of the dial indicator 154 presses against the surface of the empty drum 200. Afterwards, the detection drive member 155 drives the clamp 153 to move the dial indicator 154 in the second direction, causing the dial indicator 154 to reciprocate once in the second direction from one end of the empty drum 200, thus completing the straightness detection of the empty drum 200. It can be understood that the axis of the empty drum 200 extends approximately in the second direction.

[0063] The detection mechanism 150 also includes a second distance sensor 156, which is mounted on the fixture 153 and is used to detect the distance between the dial indicator 154 and the empty drum 200. The second distance sensor 156, the fifth drive unit 152, and the detection drive unit 155 are all electrically connected to the controller. The controller controls the stroke of the fifth drive unit 152 based on the detection data from the second distance sensor 156 to ensure stable contact between the detection end of the dial indicator 154 and the surface of the empty drum 200.

[0064] In this embodiment, the detection drive 155 is a motor, and its shaft is connected to a drive screw 157 extending in the second direction. The drive screw 157 is threadedly engaged with the clamp 153. During the rotation of the drive screw 157 driven by the detection drive 155, the clamp 153 moves along the second slide rail 151 in the second direction. To limit the movement of the furniture, in this embodiment, a stop 158 is also provided at the end of the drive screw 157 away from the detection drive 155.

[0065] After the dial indicator 154 completes one reciprocating motion in the second direction, the fifth drive component 152 drives the second slide rail 151 to descend and reset. The controller is also electrically connected to the rejection mechanism 160. The controller determines whether the straightness of the current empty drum 200 is qualified based on the detection data of the dial indicator 154, and controls the rejection mechanism 160 to perform corresponding actions based on the judgment result.

[0066] In this embodiment, there are two defective product storage sections 112, which are located on opposite sides of the conveying mechanism 130 in the second direction. Each defective product storage section 112 is equipped with a gap detection element 113, which detects whether there is a gap in the corresponding defective product storage section 112. The rejection mechanism 160, based on the detection result of the gap detection element 113, transfers empty rolls 200 with unsatisfactory straightness to the defective product storage section 112 with a gap.

[0067] The rejection mechanism 160 includes two lifting members 161 disposed on the main body 110 of the device. The two lifting members 161 are respectively located on both sides of the conveying mechanism 130 in the second direction, and are used to lift the two ends of the empty roll 200 at different heights so that the empty roll 200 reaches the defective temporary storage section 112 where there is an empty space.

[0068] Understandably, the two defective temporary storage sections 112 are equipped with empty space detection elements 113 and two lifting elements 161, all of which are electrically connected to the controller. The two lifting elements 161 are located downstream of the detection mechanism 150 and close to the two storage sections 111 respectively. When the controller determines that the straightness of the current empty drum 200 is unsuitable based on the detection data of the dial indicator 154, when the empty drum 200 reaches above the two lifting elements 161, the controller controls the two lifting elements 161 to move according to the detection results of the two empty space detection elements 113, so as to transfer the empty drum 200 to the storage section 111 where there is an empty space.

[0069] For example, if the detection data of the two empty space detection devices 113 determine that one of the storage sections 111 is full while the other storage section 111 is empty, the controller controls the lifting device 161 on the side closer to the full storage section 111 to rise, lifting the empty drum 200 at one end corresponding to the full storage section 111, while controlling the other lifting device 161 not to move, so that the empty drum 200 flips and enters the empty storage section 111 for storage.

[0070] Understandably, if the detection mechanism 150 detects that the straightness of the empty roll 200 is qualified, the empty roll 200 will not stop at the rejection mechanism 160, but will be directly transported by the conveying mechanism 130 to the cleaning mechanism 140 for cleaning.

[0071] In addition, in this embodiment, a discharge port 115 is provided on one side surface of the device body 110, and a safety stop 116 is provided at the discharge port 115. Furthermore, an inclined slide rail connecting the discharge port 115 and the storage section 111 is provided inside the device body 110. In practical applications, after the cleaned empty roll 200 falls into the storage section 111, it slides along the inclined slide rail to the discharge port 115 and is stopped by the safety stop 116 to prevent it from falling further. That is, the cleaned empty rolls 200 with acceptable straightness are ultimately stored at the discharge port 115. If there are many cleaned empty rolls 200, they are arranged sequentially within the inclined slide rail.

[0072] In summary, the empty roll buffer device 100 provided in this embodiment can store the empty roll 200 while also automatically cleaning and detecting the straightness of the empty roll 200, thereby improving production efficiency and product quality.

[0073] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
