Description

Technical Field

[0001] The utility model relates to the technical field of collating machine accessories, in particular to a turning and accelerating mechanism of a collating machine. Background Art

[0002] The collating machine is a professional post-press processing equipment that stacks single sheets of paper or book sections completed in the previous process into book blocks in page order through a page-holding mechanism. The collating machine is usually composed of a frame, a page storage table, a conveyor chain, a transmission device, a paging mechanism, a page-holding mechanism, a detection mechanism, and a book collection mechanism. At present, with the high requirements of printing companies on the speed and efficiency of post-press binding, the binding speed of post-press binding equipment has generally increased to more than 10,000 books per hour. Therefore, the stability requirements for post-press binding equipment have been greatly increased. In the post-press binding process, only book blocks with complete and correct page arrangement can be used for subsequent binding work. Therefore, the page arrangement speed and stability of the collating machine play a key role in the production efficiency of the entire post-press binding production line.

[0003] However, the acceleration mechanism of the existing collating machine is not stable enough when accelerating the book, which can easily lead to collating faults or failures. This is because the speed is greatly increased, and the book is prone to deviation after entering the page baffle with the high-speed movement of the page-gripping mechanism, and it is easy to cause blockage of the conveying channel when entering the conveying channel subsequently; if the book is made of thin paper, the book may float at the page baffle due to air buoyancy when the page-gripping mechanism puts the book down at a high speed, resulting in a slower and unstable book-gripping speed. Utility Model Content

[0004] In order to solve the technical problem that the prior art collating machine is not stable enough when feeding books at high speed, and is prone to deviation or floating, resulting in a slow feeding speed and even collating failure, the utility model provides the following technical solution.

[0005] The utility model discloses a steering and accelerating mechanism for a collating machine, comprising a steering and accelerating mechanism body for the collating machine, which is installed on one side of a horizontal plate of the collating machine and above a page receiving baffle plate at the lower end of a page holding mechanism, the steering and accelerating mechanism body for the collating machine comprising a mounting plate bolted to the horizontal plate of the collating machine, a bearing seat being installed on the upper part of the mounting plate, a rotating shaft being rotatably connected with two deep groove ball bearings in the bearing seat, an end of the rotating shaft away from the page holding mechanism being connected with a synchronous wheel located on one side of the mounting plate, an end of the rotating shaft close to the page holding mechanism being installed with a limit retaining ring and a crank block, a connecting rod being connected to the lower end of the crank block, the connecting rod being connected to at least one balance wheel, and a plurality of suction nozzles for stabilizing and accelerating the book labeling being installed on the outer circumference of the balance wheel.

[0006] As a further technical solution, there are three suction nozzles, which are evenly connected to the outer peripheral surface of the balance wheel.

[0007] As a further technical solution, the suction nozzle is made of elastic rubber material.

[0008] As a further technical solution, the center of the balance wheel is located on the axis of the rotating shaft.

[0009] As a further technical solution, there are three balance wheels distributed in a circular array with the axis of the rotating shaft as the center.

[0010] As a further technical solution, the suction nozzle is in a bell-mouth shape.

[0011] The beneficial effects of the utility model are that the collating machine uses the collating machine steering acceleration mechanism of the utility model, which is suitable for high-speed book label feeding. After the book label enters the page receiving baffle from the page gripping mechanism, the balance wheel is synchronized with the sheet feeding speed, which can make the book label stable and not drift, quickly stabilize the book label, and prevent the conveying channel from being blocked or fault alarming due to the tilting and deviation of the book label; the balance wheel and the suction nozzle make circular motion during the working process, which can not only stabilize the book label, but also provide an acceleration for the book label, creating a stable foundation for speeding up the collating, and improving the collating speed and subsequent binding efficiency.

[0017] like Figure 1 As shown, the utility model is a turning and accelerating mechanism for a collating machine, comprising a turning and accelerating mechanism body 300 for a collating machine, which is installed on one side of a horizontal plate 200 of the collating machine, and is located above a page-joining baffle at the lower end of a page-holding mechanism 100, and is used for stabilizing and accelerating a bookmark that moves at a high speed from the page-holding mechanism to the page-joining baffle.

[0018] like Figure 2 As shown, in a preferred embodiment, the main body 300 of the collating machine steering acceleration mechanism includes a mounting plate 1 bolted to the collating machine transverse plate 200, and the height of the mounting plate 1 on the collating machine transverse plate 200 can be adjusted by bolts to accommodate book signatures of different thicknesses. A bearing seat 2 is mounted on the upper part of the mounting plate 1, and two deep groove ball bearings 11 are mounted in the bearing seat 2, and the two deep groove ball bearings 11 are connected to a rotating shaft 13. The end of the rotating shaft 13 away from the page gripping mechanism 100 is connected to a synchronous wheel 12 located on one side of the mounting plate 1, and the synchronous wheel 12 is connected to the power mechanism of the collating machine, and the synchronous wheel 12 is driven by the power mechanism of the collating machine.

[0019] In a preferred embodiment, a limit stop ring 3 and a crank block 4 are installed at one end of the rotating shaft 13 close to the page-holding mechanism 100, and one end of the rotating shaft 13 is connected and fixed to the crank block 4 by a first screw 5. A connecting rod 6 is connected to the lower end of the crank block 4, and the connecting rod 6 is connected to at least one balance wheel 8, and the connecting rod 6 is connected and fixed to the balance wheel 8 by a second screw 7. A plurality of suction nozzles 9 are installed on the outer circumference of the balance wheel 8 to stabilize and accelerate the book label, and the suction nozzle 9 is connected and fixed to the outer circumference of the balance wheel 8 through a suction nozzle mounting column 10. When the synchronous wheel 12 drives the rotating shaft 13 to rotate, the crank block 4 can drive the balance wheel 8 and the suction nozzle 9 to rotate in a circle, and the balance wheel 8 is synchronized with the speed of the page-holding mechanism 100 to place the book label, and the suction nozzle 9 can make the book label stable and not drift, and quickly stabilize the book label. At the same time, during the circular motion, the balance wheel 8 and the suction nozzle 9 can also provide an acceleration to the book label to improve the stability of placing the label and the speed of collating the pages.

[0020] In a preferred embodiment, there are three suction nozzles 9, which are in a trumpet shape and are evenly connected to the outer peripheral surface of the balance wheel 8. The suction nozzles 9 are made of elastic rubber material.

[0021] In a preferred embodiment, the center of the balance wheel 8 is located on the axis of the rotating shaft 13. At this time, the contact distance between each suction nozzle 9 and the book signature is the same, which is more stable. The balance wheel 8 is not limited to one as shown in the figure. The balance wheel 8 can also be three, distributed in a circular array with the axis of the rotating shaft 13 as the center, which is more suitable for book signatures of various lengths and widths.

[0022] When the utility model is in use, when the collating machine operates at high speed, the book label is attached to the page baffle by the page gripping mechanism 100, and the book label first contacts the suction nozzle 9 on the balance wheel 8, and the balance wheel 8 is driven to rotate by the transmission of the synchronous wheel 12. When the balance wheel 8 and the suction nozzle 9 make circular motion, the suction nozzle 9 continuously stabilizes the book label and provides an acceleration to the book label to achieve the purpose of steering acceleration, and then the book label is sent to the page feeding mechanism or conveying channel of the collating machine.
