Description

Technical Field

[0001] This utility model belongs to the field of book processing technology, specifically relating to a flipping device for assembly line operations. Background Technology

[0002] In the field of book management, labeling has become an important means of improving the management efficiency of libraries, bookstores, and bookshops. With the continuous development of technology, labeling methods have gradually shifted from manual operation to mechanized automated assembly line operations, a transformation that has significantly improved work efficiency. However, in the process of automated book processing, an issue that cannot be ignored is that when books are put into the assembly line, their front and back faces are not aligned. If books with incorrect orientation are not flipped over, it will lead to inconsistent labeling positions, which in turn will affect subsequent management and identification.

[0003] To address this issue and ensure consistent label placement, the applicant filed a patent application in September 2022 with publication number CN213863039U, entitled "A Flipping Device." However, this flipping device has the following problems in practical applications:

[0004] Before the flipping device, the books are arranged and moved on the assembly line. However, when passing through the flipping device, part of the lower surface of the books moves with the assembly line, while the other part is on the clamping plate or mounting plate of the flipping device. Since the clamping plate and mounting plate do not drive the books, the books are prone to shifting and tilting after passing through the flipping device, which is inconvenient for the next process. The books need to be readjusted before entering the next process. Utility Model Content

[0005] The purpose of this invention is to provide a flipping device for assembly line operations. After passing through the flipping device, the books maintain their original direction of movement and will not tilt, facilitating the next process.

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0032] Please see Figures 1 to 3 A flipping device for assembly line operation, disposed in assembly line 1, includes: a position adjustment structure 7 and a clamping assembly 5.

[0033] The assembly line 1 is equipped with several rollers 11, with gaps 111 between adjacent rollers 11. It includes a position adjustment structure 7 installed on the outside of the assembly line 1 and a clamping assembly 5 connected to it, which is driven to move and rotate via the position adjustment structure 7. The clamping assembly 5 has clamping bars 511 that cooperate with the gaps 111. The position adjustment structure 7 drives the clamping bars 511 to retract into the gaps 111 or extend out of the roller 11 surface, thereby releasing or clamping books. Specifically, in this embodiment, the assembly line 1 is a prior art roller conveyor mechanism. The rollers 11 are rotatably mounted on support frames 12 on both sides of the top of the conveyor frame via roller bearings. The rollers 11 are connected at their ends by a synchronous belt 13. Driven by a servo motor 14, the rollers 11 rotate to convey books. The clamping bars 511 of the clamping assembly 5 are disposed in the gaps 111 between adjacent rollers 11. The clamping bars 511 are positioned slightly below the surface of the rollers 11 and are close to the upper surface of the books. During normal book movement, the clamping bars 511 do not contact the books. To automate and enable intelligent operation of production line 1, an image acquisition device and a vision system connected to the image acquisition device are utilized. The vision system and the position adjustment structure 7 are electrically connected to the controller. The image acquisition device and the vision system comprehensively determine whether the book is facing correctly based on various factors such as the image, height, width, position, and color of the book.

[0034] Using the flipping device of this utility model for assembly line operations, such as Figure 1 and Figure 2Books are fed at intervals at the beginning of production line 1. After being positioned, the books move on the surface of rollers 11. Clamping bars 511 are positioned in the gap 111 between adjacent rollers 11. Using existing image acquisition devices and vision systems, the orientation of the books on production line 1 is monitored. Books in the correct orientation proceed to the next processing step. When a book is found to be facing the wrong direction, the controller sends a signal to flip it, activating the position adjustment structure 7. Driven by the position adjustment structure 7, the clamping bars 511 extend from the gap to clamp the book. After clamping, the position adjustment structure 7 drives the clamping assembly 5 to move up and down a certain height before flipping it 180°, simultaneously flipping the book 180°. After flipping, the position adjustment structure 7 drives the clamping assembly 5 back to its original position. Books with corrected orientation continue to flow through production line 1 under the roller drive. Except during the flipping process, the lower surface of the book is in contact with production line 1, preventing it from shifting or tilting, thus avoiding the need for readjustment before entering the next processing step.

[0035] Furthermore, the position adjustment structure 7 includes a lifting assembly 2, a flipping assembly 3, and a clamping drive assembly 4; the lifting assembly 2 is installed on the outside of the assembly line 1, and the flipping assembly 3 is connected to the lifting assembly 2; the clamping drive assembly 4 is installed on the flipping assembly 3, and the clamping drive assembly 4 drives the clamping assembly 5 to clamp or release books, while the lifting assembly 2 drives the flipping assembly 3 to move up and down; the flipping assembly 3 drives the clamping assembly 5 to flip. Specifically, the clamping bar 511 is fixedly installed to the output end of the clamping drive assembly 4 by bolts. In use, the clamping drive assembly 4 is activated to drive the clamping assembly 5 to clamp the books, and after clamping, the lifting assembly 2 is activated, synchronously driving the flipping assembly 3 and the clamping assembly 5 to rise to a predetermined height, such as... Figure 1 The flipping component 3 is activated, driving the clamping component 5 to flip 180°, thus flipping the books 180°. After the flip is completed, the lifting component 4 is activated in the opposite direction, and the clamping component 5 falls back into the gap 111. The books continue to flow out of the production line 1 under the conveying action of the roller 11. Books with different orientations work on the same production line 1, and after being processed by the device, their orientations are unified.

[0036] Please see Figure 1 and Figure 3 Furthermore, the lifting assembly 2 includes a first drive source 21 and a frame 22. The frame 22 is mounted on the output end of the first drive source 21, and the tilting assembly 3 is mounted on the frame 22. Specifically, a mounting bracket 15 is provided on one side of the production line 1, and the first drive source 21 is fixedly mounted on the mounting bracket 15 with hexagonal bolts. In use, the first drive source 21 is started, and the frame 22 drives the tilting assembly 3 to move up and down, thereby causing the clamping assembly 5 to fall back to the gap 111 or move away from the production line 1. When it moves away from the production line 1, the clamping assembly 5 can be tilted 180° under the drive of the tilting assembly 3. Preferably, the first drive source 21 is an electric push rod.

[0037] Furthermore, the lifting assembly 2 also includes a cable chain 23, one end of which is mounted on the frame 22 and the other end on the production line 1. Specifically, the other end of the cable chain 23 is mounted on the mounting frame 15. With this structure, the frame 22 slides more smoothly on the mounting frame 15.

[0038] Please see Figure 1 , Figure 3 and Figure 4 Furthermore, the clamping assembly 5 includes a first clamping plate 51 and a second clamping plate 52, which are respectively connected to the clamping drive assembly 4. The first clamping plate 51 and / or the second clamping plate 52, in conjunction with the guide device 53, move closer or further apart under the drive of the clamping drive assembly 4. Both the first clamping plate 51 and the second clamping plate 52 are provided with clamping strips 511. Specifically, in this embodiment, "and / or" describes three situations: under the drive of the clamping drive assembly 4, the first clamping plate 51 is moved alone, the second clamping plate 52 is moved alone, and the first clamping plate 51 and the second clamping plate 52 are moved simultaneously, so that the first clamping plate 51 and the second clamping plate 52 move closer or further apart, thereby clamping or releasing the book. In use, the upper surface of the first clamping plate 51 is not higher than the top of the roller 11, and the second clamping plate 52 is located above the top of the roller 11 and at a predetermined distance from the top of the roller 11, so as not to interfere with the normal passage of the book. When a book facing the wrong direction is detected, the clamping drive assembly 4 is activated, driving the first clamping plate 51 and / or the second clamping plate 52 to move closer together, thereby clamping the book. The lifting assembly 2 is then activated, raising the book to a certain height. The flipping assembly 3 is then activated, rotating the clamping assembly 5 180°, thus flipping the book. At this point, the positions of the first clamping plate 51 and the second clamping plate 52 are exactly reversed. After the flipping is complete, the lifting assembly 2 is activated in the opposite direction, with the second clamping plate 52 positioned in the gap between the rollers, and the first clamping plate 51 positioned below the rollers for the next flipping operation. Preferably, the first clamping plate 51 and the second clamping plate 52 are symmetrically arranged, the clamping drive assembly 4 is a cylinder, and the flipping assembly 5 is a motor.

[0039] Furthermore, the first clamping plate 51 also includes a first support block 512, with one end of the clamping strips 511 of the first clamping plate evenly spaced on the surface of the first support block 512, and the other end suspended; the second clamping plate 52 also includes a second support block 521, with one end of the clamping strips 511 of the second clamping plate evenly spaced on the surface of the second support block 521, and the other end suspended. Specifically, the width of the clamping strips 511 is smaller than the gap between adjacent rollers 11. The support frame 12 on the side of the assembly line 1 near the flipping assembly 3 is provided with a groove 121, and the position of the groove 121 corresponds to the gap 111 between two adjacent rollers 11. The first support block 512 is located outside the support frame 12. The function of opening the groove 121 is to form a certain space below the gap 111, so that the clamping strips 511 of the first clamping plate or the clamping strips 511 of the second clamping plate can move down to a suitable position to facilitate the passage of books on the rollers 11. Preferably, the clamping strips 511 of the first clamping plate and the corresponding clamping strips 511 of the second clamping plate are on the same vertical horizontal plane, so that the force direction is in the same straight line when clamping the book, reducing the damage to the book caused by the clamping force. With this structure, the clamping assembly 5 can adaptively clamp according to the thickness of the book.

[0040] Please see Figure 4 Furthermore, the clamping bar 511 is provided with a weight-reducing groove 515. Specifically, the cross-section of the weight-reducing groove 515 includes, but is not limited to, a C-shape, a square shape, or an O-shape. Preferably, the first support block 512 and the second support block 521 are hollow square tubes. This structure reduces the weight of the clamping assembly 5, thereby reducing the energy consumption of the device.

[0041] Please see Figure 3Furthermore, the guiding device 53 includes a guide seat 531 and a guide rod 532. The guide seat 531 is fixedly installed on the output end of the flipping assembly 3 by bolts. The guide seat 531 is provided with a working cavity and a guide hole 533. The clamping drive assembly 4 is installed in the working cavity of the guide seat 531. The output end of the clamping drive assembly 4 passes through the guide seat and is connected to the clamping assembly 5. One end of the guide rod 532 is installed on the clamping assembly 5, and the other end slides along the guide hole 533. Specifically, in Embodiment 1, a movable first clamping plate 51 is used. A set of clamping drive components 4 is installed in the working cavity. The output end of the clamping drive components 4 passes through a guide seat 531 and is connected to the first clamping plate 51. The first clamping plate 51 is provided with an adapter seat 513, which has several stepped holes 514. The end of the output end of the clamping drive components 4 is provided with an external thread. A first nut is used to fix the output end of the clamping drive components 4 to the adapter seat 513 through a threaded connection. One end of the guide rod 532 is provided with an external thread. A second nut is used to fix the guide rod 532 to the adapter seat 513 through a threaded connection, and the other end slides along the guide hole 533. Preferably, the guide rod 532 is parallel to the output shaft of the clamping drive components 4 and is arranged diagonally. In use, the output end of the clamping drive components 4 extends or retracts, thereby moving the first clamping plate 51 away from or closer to the second clamping plate 52. A guide device 53 is provided to make the first clamping plate 51 move stably in a predetermined direction. The principle of moving the second clamping plate 52 is the same as that of moving the first clamping plate 51.

[0042] In Embodiment 2, the first clamping plate 51 and the second clamping plate 52 are moved simultaneously. The guide device 53 is provided with two sets. The two sets of clamping drive components 4 are respectively set in the corresponding working cavities. The output ends of the two sets of clamping drive components 4 are opposite in direction. One set of output ends is installed on the first clamping plate 51, and the other set of output ends is installed on the second clamping plate 52. The sliding ends of the guide rod 532 are arranged facing each other.

[0043] Please see Figure 5 Furthermore, it also includes a blocking component 6, which includes a support plate 61, a sliding plate 62, and a second drive source 63. The support plate 61 is installed in the production line 1, the second drive source 63 is installed on the support plate 61, and the sliding plate 62 is installed at the output end of the second drive source 63. Specifically, the support plate 61 is installed below the roller 11 and below the flipping component 3, and the sliding plate 62 is located in the gap 111. The second drive source 63 drives the sliding plate 62 to extend above the roller 11 or retract below the roller 11. When a book with the correct orientation passes through the production line 1, the second drive source 63 is in standby mode. When a book with the reverse orientation is detected, the second drive source 63 is activated, and the sliding plate 62 extends out of the gap from the roller 11, preventing the reverse-oriented book from flowing into the next process. When the reverse-oriented book reaches the sliding plate 62, a flipping operation is performed.

[0044] Furthermore, the support plate 61 has a boss 611 on its end face near the sliding plate 62, and the sliding plate 62 has a slider 621. The slider 621 has a groove 622 that mates with the boss 611, and the sliding plate 62 slides along the boss 611. Specifically, there are two sets of bosses 62, spaced apart on the surface of the support plate 61, and correspondingly, there are also two sets of sliders 621. With this structure, the sliding plate 62 moves oriented and stably along the support plate 61.

[0045] This utility model discloses a flipping device for assembly line operations. A lifting assembly 2, a flipping assembly 3, and a clamping drive assembly 4 are integrated and positioned above the assembly line 1. The clamping assembly 5 is disposed within rollers 11. Books facing the correct orientation pass directly on the assembly line 1. When books facing the opposite direction flow by, the controller sends a signal to flip them. The clamping drive assembly 4 drives the clamping assembly 5 to clamp the books facing the opposite direction. When the lifting assembly 2 drives the clamping assembly 5 to rise to a predetermined height, the flipping assembly 3 drives the clamping assembly 5 to flip 180° above the assembly line 1. After flipping, the clamping assembly 5 falls back between the rollers 11, and the books facing the correct orientation continue to pass through the assembly line 1. During the assembly line transport process, the lower surface of the books remains in contact with the rollers, preventing them from shifting or tilting, thus avoiding the need for readjustment before entering the next process. A blocking assembly 6 is provided to prevent books facing the opposite direction from flowing into the next process.
