Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to an automatic reel feeding device. Background Art

[0002] The existing film reels are generally fed in two forms. One is manual feeding by workers, but in this way, at least one worker is required to stay near the equipment all day long, resulting in high labor intensity and high labor cost. The other is automatic feeding by an automatic reel feeding device. The existing reel feeding devices usually use a three-axis manipulator to clamp the reel in the material tank onto the bearing table of the shaft threading. However, due to the very complex structure of the three-axis manipulator and the need for precise debugging of the accuracy of the manipulator to grasp the reel, its control is complex, and debugging and maintenance are troublesome, resulting in too high production costs and being unfavorable for the production of films. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an automatic reel feeding device with automatic feeding, simple structure and low cost.

[0004] To achieve the above purpose, the automatic reel feeding device provided by the utility model includes a frame, a feeding device, a supply device and a shaft threading device. The feeding device includes a storage tank which is inclinedly arranged on the frame and can accommodate the reels in a single-layer arrangement, so that the reels automatically roll towards the output end; the height of the output end of the storage tank is greater than the height of the bearing table of the shaft threading device; the supply device is arranged between the feeding device and the shaft threading device; the supply device includes a turning groove, a driving device, a first blocking device and a second blocking device. The turning groove is pivotally connected to the frame and has openings at both ends; the input end of the turning groove can be docked with the output end of the feeding device, and the output end can be docked with the bearing table of the shaft threading device; the first blocking device is arranged at the output end of the storage tank and can block or release the first reel located at the output end of the storage tank; the second blocking device is arranged at the output end of the storage tank and can block or release the second reel located at the output end of the storage tank; the driving device is arranged on the frame and can drive the turning groove to rotate, so that both ends of the turning groove are respectively connected or disconnected from the feeding device and the shaft threading device; the shaft threading device is used for threading the central shaft through the reel on the bearing table to form a winding roll.

[0005] Compared with the prior art, since the storage tank of the feeding device of the present utility model is set to be inclined, the reel on the storage tank can automatically roll downward under the action of gravity for output. A supply device is further arranged between the feeding device and the shaft-passing device. By pivotally connecting the flipping tank to the frame and then using a driving device to drive the flipping tank to rotate, the two ends of the flipping tank are respectively connected to or disconnected from the feeding device and the shaft-passing device. At the same time, a second blocking device is used to block the second reel on the storage tank, and a first blocking device is used to automatically release the first reel on the storage tank, so that the flipping tank can automatically release one reel each time it docks with the storage tank, and the reel rolls through the flipping tank under the action of gravity and then falls onto the bearing platform of the shaft-passing device, achieving the purpose of automatically loading the reel. Therefore, the present utility model can realize automatic feeding of the reel without setting a multi-axis manipulator, and greatly simplifies the structure of the equipment, significantly reducing the cost of the equipment.

[0006] Preferably, the first blocking device is a baffle, and the baffle is arranged at one end of the flipping tank close to the output end of the storage tank to release the first reel when following the flipping tank to connect with the storage tank, or block the first reel when disconnecting from the storage tank. By setting the baffle, the baffle can rotate following the rotation of the flipping tank, and thus can automatically block the first reel from falling when the flipping tank disconnects from the storage tank, and can automatically release the first reel when the flipping tank docks with the storage tank, without adding additional driving force, effectively simplifying the structure of the equipment and further reducing the cost of the equipment.

[0007] Preferably, the second blocking device includes a cylinder and a stopper. The cylinder is arranged on the frame and the output end is connected to the stopper, and the stopper can move close to or away from the storage tank. By using the cylinder to drive the stopper to block or release the second reel, the control is very simple.

[0008] Preferably, a trigger switch is arranged at the output end of the storage tank, and the trigger switch is in communication connection with the second blocking device to trigger the trigger switch when the flipping tank docks with the storage tank, so that the second blocking device blocks the second reel, or to leave the trigger switch when the flipping tank disconnects from the storage tank, so that the second blocking device releases the second reel. By associating the flipping tank with the second blocking device using the trigger switch, the control can be made simpler, the control time can be more accurate, and the degree of automation is high.

[0009] Preferably, the width of the material storage groove is 5 to 10 millimeters larger than the width of the reel. This can both limit the reel to prevent large skewing during the material feeding process and avoid the reel getting stuck on the material storage groove, ensuring smooth material feeding.

[0010] Preferably, the shaft-passing device includes a fixed table, a bearing table, a lifting drive mechanism, a moving table, a horizontal drive mechanism, and a clamping mechanism; the lifting drive mechanism is arranged on the fixed table and its output end is connected to the bearing table to drive the bearing table to rise or fall; the clamping mechanism is arranged on the moving table to clamp the central shaft for passing through the reel; the horizontal drive mechanism is arranged on the fixed table and its output end is connected to the moving table to drive the moving table to move horizontally relative to the fixed table so that the central shaft can pass through the reel.

[0011] Specifically, the bearing table has a V-shaped structure, and the extension height of the side of the V-shaped structure away from the flipping groove is greater than the extension height of the side close to the flipping groove. By setting the bearing table into a V-shaped structure, the reel can be quickly positioned, preventing the reel from shaking and ensuring the accuracy of shaft passing.

[0012] Specifically, an inductor for detecting the reel is provided on the bearing table. This can ensure the smoothness of each feeding and shaft passing, improving the stability and reliability of operation. Description of the Drawings

[0016] To describe in detail the technical content, structural features, and achieved effects of the present invention, the following is a detailed description in conjunction with the embodiments and with reference to the drawings.

[0017] As Figure 1 and Figure 2As shown, the automatic reel loading device 100 of the present utility model includes a feeding device 1, a supply device 2, a shaft threading device 3 and a frame (not shown in the figure). The feeding device 1 includes a storage tank 11. The storage tank 11 is inclinedly arranged on the frame and can accommodate the reels 200 in a single-layer arrangement, so that the reels 200 automatically roll towards the output end. The height of the output end of the storage tank 11 is greater than the height of the loading table of the shaft threading device 3. The width of the storage tank 11 is 5 to 10 millimeters larger than the width of the reel 200. In this way, the reels 200 can be limited, preventing the reels 200 from being greatly skewed during the feeding process, and the reels 200 can be prevented from getting stuck on the storage tank 11, ensuring smooth feeding. The supply device 2 is arranged between the feeding device 1 and the shaft threading device 3. The supply device 2 includes a flipping tank 21, a driving device 22, a first blocking device 23 and a second blocking device 24. In this embodiment, the driving device 22 is a cylinder. The flipping tank 21 is pivotally connected to the frame and has openings at both ends. The input end of the flipping tank 21 can be docked with the output end of the feeding device 1, and the output end can be docked with the loading table 32 of the shaft threading device 3. The first blocking device 23 is arranged at the output end of the storage tank 11 and can block or release the first reel 200 located at the output end of the storage tank 11. The second blocking device 24 is arranged at the output end of the storage tank 11 and can block or release the second reel 200 located at the output end of the storage tank 11. The driving device 22 is arranged on the frame and can drive the flipping tank 21 to rotate, so that the two ends of the flipping tank 21 are respectively connected or disconnected from the feeding device 1 and the shaft threading device 3. The shaft threading device 3 is used to thread the central shaft 300 through the reel 200 on the loading table 32 to form a winding roll.

[0018] Please refer to again Figure 1 , a trigger switch 5 is provided at the output end of the storage tank 11. The trigger switch 5 is communicatively connected to the second blocking device 24 to trigger the trigger switch 5 when the flipping tank 21 is docked with the storage tank 11, so that the second blocking device 24 blocks the second reel 200 or leaves the trigger switch 5 when the flipping tank 21 is disconnected from the storage tank 11, so that the second blocking device 24 releases the second reel 200. By associating the flipping tank 21 with the second blocking device 24 using the trigger switch 5, the control can be made simpler, the control time can be more accurate, and the degree of automation is high.

[0019] Please refer to again Figure 1, the first blocking device 23 is a baffle plate, which is arranged at one end of the flipping groove 21 close to the output end of the storage tank 11, so as to follow the flipping groove 21 to release the first reel 200 when connected to the storage tank 11, or block the first reel 200 when disconnected from the storage tank 11. By arranging the baffle plate, the baffle plate can rotate following the rotation of the flipping groove 21, so that when the flipping groove 21 is disconnected from the storage tank 11, it can automatically block the first reel 200 from falling, and when the flipping groove 21 is docked with the storage tank 11, it can automatically release the first reel 200, without adding additional driving force, effectively simplifying the structure of the equipment and further reducing the cost of the equipment.

[0020] Please refer to again Figure 1 , the second blocking device 24 includes a cylinder 241 and a stopper 242. The cylinder 241 is arranged on the frame and its output end is connected to the stopper 242. The stopper 242 can move close to or away from the storage tank 11. By using the cylinder 241 to drive the stopper 242 to block or release the second reel 200, its control is very simple.

[0021] Please refer to again Figure 2 , the shaft-passing device 3 includes a fixed platform 31, a bearing platform 32, a lifting driving mechanism 33, a moving platform 34, a horizontal driving mechanism 35 and a clamping mechanism 36; the lifting driving mechanism 33 is arranged on the fixed platform 31 and its output end is connected to the bearing platform 32 to drive the bearing platform 32 to rise or fall; the clamping mechanism 36 is arranged on the moving platform 34 to clamp the central shaft 300 for passing through the reel 200; the horizontal driving mechanism 35 is arranged on the fixed platform 31 and its output end is connected to the moving platform 34 to drive the moving platform 34 to move horizontally relative to the fixed platform 31, so that the central shaft 300 can pass through the reel 200. Specifically, the bearing platform 32 has a V-shaped structure, and the extension height of the side of the V-shaped structure away from the flipping groove 21 is greater than the extension height of the side close to the flipping groove 21. By arranging the bearing platform 32 in a V-shaped structure, the reel 200 can be quickly positioned, preventing the reel 200 from shaking and ensuring the accuracy of shaft-passing. More specifically, a sensor 37 for detecting the reel 200 is arranged on the bearing platform 32. This can ensure the smoothness of each feeding and shaft-passing, improving the operation stability and reliability. In addition, in this embodiment, the lifting driving mechanism 33 can adopt the form of being driven by a cylinder 241; the horizontal driving mechanism 35 can adopt the form of a motor driving a pulley and a belt, using the belt to drive the moving platform 34 to move horizontally, or can also adopt the form of a motor driving a gear and a rack. Its specific structure is well-known to those skilled in the art and will not be described in detail here.

[0022] Combining the above and Figure 1 and Figure 3 , the feeding principle of the automatic reel loading device 100 of the present utility model will be described in detail as follows:

[0023] First, place the reel 200 into the storage slot 11. Under the action of gravity, the reel 200 rolls along the storage slot 11 to the output end of the storage slot 11, and then is blocked by the baffle to be arranged in a single layer. After that, the lifting drive mechanism 33 drives the carrier 32 to rise to the highest point. At this time, the cylinder 241 of the second blocking device 24 starts to drive the block 242 to move close to the output end of the storage slot 11, and then inserts between the first reel 200 and the second reel 200. At this time, the block 242 blocks the second reel 200 from rolling down. After that, the extending end of the driving device 22 extends outwards to drive the flipping slot 21 to flip, so that the output end of the flipping slot 21 is docked with the carrier 32, and the input end of the flipping slot 21 is docked with the output end of the storage slot 11. At the same time, after the baffle rotates with the flipping slot 21, the baffle leaves the output end of the storage slot 11 and releases the first reel 200. Therefore, the first reel 200 rolls from the storage slot 11 into the flipping slot 21 under the action of gravity, and finally rolls from the flipping slot 21 onto the carrier 32. At this time, the feeding is completed, and the reel 200 located on the carrier 32 can wait for shaft threading. In addition, after the feeding is completed, the driving device 22 drives the flipping slot 21 to rotate in the reverse direction again. At this time, the output end of the flipping slot 21 leaves the carrier 32, the input end of the flipping slot 21 leaves the output end of the storage slot 11, and at the same time, the baffle rotates with the flipping slot 21 and then blocks again at the output end of the storage slot 11, thereby blocking the reel 200 in the storage slot 11 from falling. Then, since the baffle leaves the trigger switch 5, the trigger switch 5 can send a signal to the control system, so that the cylinder 241 of the second blocking device starts and drives the block 242 to leave the storage slot 11, so that the reel 200 can roll forward to the baffle to prepare for the next blanking.

[0024] During shaft threading, the clamping mechanism 36 clamps a central shaft 300 at one end of the fixed table 31, and the central axis of the central shaft 300 is coaxial with the central axis of the reel 200. At this time, the horizontal drive mechanism 35 drives the moving table 34 to translate in the direction close to the fixed table 31, so that the central shaft 300 is inserted into the reel 200. When the shaft threading is completed, the clamping mechanism 36 releases the central shaft 300, and the whole formed by the central shaft 300 and the reel 200 waits for transfer on the carrier 32.

[0025] Compared with the prior art, since the storage tank 11 of the feeding device 1 of the present utility model is set to be inclined, the reel 200 on the storage tank 11 can automatically roll downward under the action of gravity for output. Moreover, a supply device 2 is arranged between the feeding device 1 and the shaft-passing device 3. By pivotally connecting the flipping tank 21 to the frame and then using the driving device 22 to drive the flipping tank 21 to rotate, the two ends of the flipping tank 21 are respectively connected to or disconnected from the feeding device 1 and the shaft-passing device 3. At the same time, the second blocking device 24 blocks the second reel 200 on the storage tank 11, and the first blocking device 23 automatically releases the first reel 200 on the storage tank 11, so that the flipping tank 21 can automatically release one reel 200 every time it docks with the storage tank 11, and the reel 200 rolls through the flipping tank 21 under the action of gravity and then falls onto the bearing platform 32 of the shaft-passing device 3, achieving the purpose of automatically loading the reel 200. Therefore, the present utility model can realize the automatic feeding of the reel 200 without setting a multi-axis manipulator, and the structure of the equipment is greatly simplified, greatly reducing the cost of the equipment.

[0026] The above-disclosed are only the preferred examples of the present utility model, and of course, the scope of the rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model.
