Description

Technical Field

[0001] This utility model relates to the field of material handling technology, and in particular to a lifting and handling mechanism. Background Technology

[0002] In the automated production process of books in the printing and binding industry, after processes such as folding, cutting, binding, and stacking, books need to be transferred to the next stage, such as packaging and palletizing, via conveyor belt. The conveyor belt transfer of stacked books is a key step connecting the preceding and following processes, directly affecting the continuity of the production line and the integrity of the book's appearance.

[0003] In existing technologies, the transfer of stacked books is generally achieved through a direct push method. Specifically, a pusher plate is installed on one side of the stacking platform. After a preset number of books are neatly stacked, the pusher plate pushes the entire stack of books directly from the stacking platform to an adjacent conveyor belt in a horizontal direction, relying on the friction of the conveyor belt to continue transporting the books. However, the above-mentioned existing transfer method has obvious drawbacks in practical applications. The sides or cover edges of the stacked books are prone to sliding friction with the connection between the stacking platform and the conveyor belt. If the force is not properly controlled during the pusher plate's push, it may also cause the edges of the entire stack of books to be squeezed and deformed. In addition, if there are small protrusions or impurities on the surface of the conveyor belt, the bottom of the directly pushed books is easily scratched, affecting the product appearance qualification rate and making it difficult to meet the requirements of high-quality and high-efficiency production.

[0034] Please refer to Figure 1-2 The lifting and transporting mechanism in the embodiments of this utility model will now be described.

[0035] Please refer to Figure 1 This application provides a lifting and transporting mechanism, including a mounting plate 1, a connecting plate 2, a book lifting mechanism 3, a book pressing mechanism 4, and a horizontal drive mechanism 5;

[0036] The horizontal drive mechanism 5 is connected to the frame, and the connecting plate 2 is connected to the horizontal drive mechanism 5. The connecting plate 2 is vertically set at the lower end of the mounting plate 1. The horizontal drive mechanism 5 drives the connecting plate 2 to move so as to move the mounting plate 1.

[0037] A book-lifting mechanism 3 for lifting books is provided below the mounting plate 1;

[0038] Above the mounting plate 1 is a book-pressing mechanism 4 for clamping the book with the book-lifting mechanism 3. The book-pressing mechanism 4 is set in correspondence with the book-lifting mechanism 3.

[0039] Specifically, the horizontal drive mechanism 5 drives the mounting plate 1 to move to one end near the stacking platform, so that the book lifting mechanism 3 is positioned below the stacked books. The book lifting mechanism 3 lifts the stacked books from below, and the book pressing mechanism 4 works with the book lifting mechanism 3 from above to clamp the books. The horizontal drive mechanism 5 drives the mounting plate 1 and the clamped books to move horizontally through the connecting plate 2, and finally places the books stably on the conveyor belt. After the books are lifted, they are separated from the contact surface. There is no friction during the handling process, which realizes the lifting-type frictionless handling of books, improves the product appearance qualification rate, ensures the continuity of the production process, improves production efficiency, and is conducive to adapting to the stable operation requirements of automated production lines.

[0040] In another embodiment of this application, please refer to Figure 1-2 The book-lifting mechanism 3 includes a first driving component 31 and a first pressure plate 32;

[0041] The connecting plate 2 is provided with a first slide rail 21 extending in the vertical direction, and a first pressure plate 32 is slidably disposed on the first slide rail 21; a first driving member 31 is disposed on the connecting plate 2, and the output end of the first driving member 31 is connected to the first pressure plate 32, and the first driving member 31 drives the first pressure plate 32 to move up and down along the first slide rail 21.

[0042] Specifically, the first slide rail 21 on the connecting plate 2 provides vertical guidance and constraint for the first pressure plate 32. The first driving member 31 is set as a cylinder, with the top of the piston rod connected to the lower surface of the first pressure plate 32. The first driving member 31 drives the first pressure plate 32 to move up and down along the slide rail. The driving force is transmitted in the vertical direction to ensure that the first pressure plate 32 remains horizontal during the lifting process and to prevent the book from tilting due to the offset of the pressure plate.

[0043] In another embodiment of this application, please refer to Figure 1 The book pressing mechanism 4 includes a second driving component 41 and a second pressing plate 42;

[0044] A support plate 6 is provided on the mounting plate 1, and the book pressing mechanism 4 is located on the side of the support plate 6 facing the book lifting mechanism 3;

[0045] The second driving component 41 is mounted on the support plate 6. The output end of the second driving component 41 is connected to the second pressure plate 42. The second driving component 41 drives the second pressure plate 42 to move up and down. The second pressure plate 42 corresponds vertically to the first pressure plate 32.

[0046] Specifically, the second driving component 41 drives the second pressure plate 42 to move up and down, and by adjusting the distance between the second pressure plate 42 and the first pressure plate 32, it adapts to the clamping requirements of books of different thicknesses.

[0047] In another embodiment of this application, please refer to Figure 1 The book pressing mechanism 4 also includes a third driving component 43 and a third pressing plate 44;

[0048] The second driving component 41 is disposed on the third pressure plate 44;

[0049] The third driving member 43 is disposed on the support plate 6 and located above the third pressure plate 44. The output end of the third driving member 43 is connected to the third pressure plate 44 and is used to drive the third pressure plate 44 to move up and down along the second slide rail 61 so as to drive the second driving member 41 and the second pressure plate 42 to move synchronously.

[0050] Specifically, the third driving component 43 drives the third pressure plate 44 to move up and down along the second slide rail 61, and the second driving component 41 drives the second pressure plate 42 to move up and down relative to the third pressure plate 44. The force of the third driving component 43 is greater than the force of the second driving component 41. During the process of lifting and translating the book, the third driving component 43 provides a downward pressing force, causing the third pressure plate 44 to move down, the second pressure plate 42 to press down, and the first pressure plate 32 to lift up. The second pressure plate 42 and the first pressure plate 32 clamp the book. The two-stage drive combined with the slide rail guide not only expands the clamping height adjustment range, but also ensures the stability of the movement process, and adapts to books with greater thickness differences.

[0051] In another embodiment of this application, please refer to Figure 1 The horizontal drive mechanism 5 includes a fourth drive component 51 and a sprocket assembly 52;

[0052] The fourth drive component 51 is fixed on the frame. The output end of the fourth drive component 51 is connected to the sprocket assembly 52. ​​The connecting plate 2 is set on the sprocket assembly 52. ​​The fourth drive component 51 drives the sprocket assembly 52 to make the connecting plate 2 move the mounting plate 1 back and forth.

[0053] Specifically, the fourth drive component 51 is configured as a servo motor and a reducer. The output shaft of the fourth drive component 51 is connected to the driving sprocket of the sprocket assembly 52. ​​The driven sprocket of the sprocket assembly 52 is rotatably mounted at the other end of the frame. The chain sleeve forms a closed transmission between the driving sprocket and the driven sprocket. The connecting plate 2 is fixedly connected to the chain. The fourth drive component 51 and the sprocket assembly 52 cooperate in transmission to ensure that the books are accurately conveyed to the rear conveyor belt. Rotation and conveying are carried out synchronously, shortening the process time and increasing the production line capacity. The chain drive has a strong load-bearing capacity, can adapt to continuous production, and has no risk of chain breakage.

[0054] In another embodiment of this application, please refer to Figure 1It also includes a first guide component 7, which extends along the front-rear direction and is disposed on the frame, and a connecting plate 2 is disposed on the first guide component 7.

[0055] Specifically, the first guide component 7 is provided with two guide rails. The two guide rails are symmetrically distributed in the vertical direction on the connecting plate 2. The slider is connected to the connecting plate 2 and slides along the guide rails, providing guiding constraints for the horizontal movement of the connecting plate 2 and preventing the connecting plate 2 from twisting or deflecting due to the lateral component of the horizontal driving force.

[0056] In another embodiment of this application, please refer to Figure 1 It also includes a second guide assembly 8, which extends along the front-rear direction and is disposed on the frame, and a mounting plate 1 is disposed on the second guide assembly 8.

[0057] Specifically, the second guide assembly 8 is provided with two guide rails, which are symmetrically distributed at both ends of the mounting plate 1. The corresponding two guide blocks are fixed to both ends of the mounting plate 1, forming a symmetrical guide structure, which further restricts the horizontal torsion and vertical offset of the mounting plate 1 and enhances the stability of movement. The symmetrical guide structure eliminates horizontal torsion, reduces the deviation of the conveying position, and is suitable for the requirements of high-precision printing production lines; the forces at both ends of the mounting plate 1 are balanced, reducing the local stress between the connecting plate 2 and the chain, and extending the service life of the chain.

[0058] In another embodiment of this application, please refer to Figure 1 It also includes a third guide component 9, which is disposed on the third pressure plate 44 and extends in the vertical direction, and a second pressure plate 42 is disposed on the third guide component 9.

[0059] Specifically, the third guide component 9 is provided with two guide rails, which are respectively set on both sides of the second drive component 41. The third guide rail is fixed on the third pressure plate 44 in the vertical direction to ensure that the second pressure plate 42 remains horizontal when moving and is precisely aligned with the first pressure plate 32, so as to avoid uneven force on the book when clamping.

[0060] In another embodiment of this application, please refer to Figure 1 It also includes a stroke adjustment block 10, which is adjustablely positioned and connected to the sprocket assembly 52.

[0061] Specifically, the stroke adjustment block 10, through an adjustable connection structure such as an oblong hole or a long hole, cooperates with the sprocket assembly 52 and is specifically set on the chain. When the fixing piece is loosened, it can move along the chain extension direction of the sprocket assembly 52, changing its relative position with the sprocket assembly 52. ​​Since the stroke adjustment block 10 is fixed to the connecting plate 2, its position change will synchronously drive the connecting plate 2 to change the connection position with the sprocket assembly 52, thereby adjusting the horizontal movement range of the mounting plate 1 driven by the connecting plate 2, realizing flexible adjustment of the horizontal drive stroke. After adjustment, tightening the fixing piece will lock the position of the stroke adjustment block 10, ensuring stable stroke during operation.

[0062] In another embodiment of this application, please refer to Figure 1-2 The specific timing sequence of the automated control actions is as follows:

[0063] 1. Trigger: Once the photoelectric sensor on the stacking platform detects that a preset number of books have been stacked, it sends a ready signal;

[0064] 2. Positioning: The horizontal drive mechanism 5 is activated, which moves the mounting plate 1 and the book lifting mechanism 3 to directly below the book;

[0065] 3. Lifting: The first driving component 31 drives the first pressure plate 32 to move upward along the first slide rail 21, lifting the books from the stacking platform;

[0066] 4. Clamping: The second driving member 41 first drives the second pressure plate 42 to press down close to the book, and then the third driving member presses down the third pressure plate 44. The second slide rail 61 moves downward, causing the second pressure plate 42 to cooperate with the first pressure plate 32 to clamp the book.

[0067] 5. Transfer: The horizontal drive mechanism 5 drives the mounting plate 1 and the clamped books to move along the first and second guide components 8 to directly above the conveyor belt;

[0068] 6. Placement: The second driving component 41 and the third driving component 43 synchronously reset, the second pressure plate 42 rises, and the first driving component 31 drives the first pressure plate 32 to move downward, placing the book stably on the conveyor belt. Subsequently, the horizontal driving mechanism 5 drives the mounting plate 1 to reset to the initial position, waiting for the next cycle. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
