Description

Technical Field

[0001] The present invention relates to the field of notebook and booklet manufacturing machinery, and particularly to a combined conveying device for double-cover-back lines of notebooks. Background Art

[0002] Currently, the existing domestic notebook (booklet) production lines basically start from a roll of paper and go through printing, slitting, collecting, feeding front and back covers, aligning paper, gluing, cover-back binding, conveying, and horizontal and vertical cutting to form notebooks. Since there is only one line in the gluing part and the glue is not easy to dry, the speed is relatively slow, while the speeds of the printing and cutting parts can be very fast. This restricts the speed of the entire production line and greatly restricts the production efficiency.

[0003] In order to solve the problem that the original product's glue binding and cover-back binding speed is too slow to match the printing and cutting speeds, two glue binding lines are adopted, which can greatly improve the production efficiency. The difficulty in adopting two glue binding lines lies in how to divide the printed paper stack (i.e., the front and back covers have been fed) into two paths and send them to the two glue binding lines in sequence. The patent with the publication number CN210122412U discloses a paging device for diverting a paper stack for diversion.

[0004] However, another difficulty in adopting two glue binding lines lies in how to send the booklets that have been glue-bound on the two glue binding lines to the cutting line in sequence to ensure that the entire production line is continuously automated. Therefore, it is necessary to design a combined conveying device to alternately convey the glue-bound booklets on the production line to the cutting production line to match the speeds of printing, glue binding, and cutting. Summary of the Invention

[0005] The purpose of the present invention is to propose a combined conveying device for double-cover-back lines of notebooks, which alternately conveys the glue-bound booklets from two glue binding production lines to the cutting production line through a mechanical structure to achieve efficient, continuous, and automated production.

[0024] The technical solutions of the present invention will be further described in detail below with reference to the drawings and embodiments.

[0025] The present invention provides a unified conveying device for the double-cover back lines of notebooks, as Figures 1 to 3 shown, in which a preferred embodiment of the present invention is shown.

[0026] As Figure 1As shown in the figure, the combined conveying device for the double-cover back line of the notebook includes: a conveying support. At least a first notebook conveying mechanism 11 and a second notebook conveying mechanism 12 are provided on the upper part of the conveying support. The conveying directions of the first notebook conveying mechanism 11 and the second notebook conveying mechanism 12 are the same and they are arranged adjacent to each other at the head and tail.

[0027] As Figure 3 shown in the figure, the first notebook conveying mechanism 11 includes a first driving roller 111, a first driven roller 112 and a first conveyor belt tensioning roller 113 that are rotatably arranged on the conveying support. A first conveyor belt 114 is provided on the first driving roller 111, the first driven roller 112 and the first conveyor belt tensioning roller 113. A first conveying sprocket 115 is provided at the end of the first driving roller 111. The first conveying sprocket 115 is driven by a chain to a rotating power unit. Preferably, the second notebook conveying mechanism 12 is similar to the first notebook conveying mechanism 11. The second notebook conveying mechanism 12 includes a second driving roller 121, a second driven roller and a second conveyor belt tensioning roller 123 that are rotatably arranged on the conveying support. A second conveyor belt 124 is provided on the second driving roller 121, the second driven roller and the second conveyor belt tensioning roller 123. A second conveying sprocket 125 is provided at the end of the second driving roller 121. The second conveying sprocket 125 is driven by a chain to the first conveying sprocket 115. Preferably, the rotating power unit includes a motor or an internal combustion engine, which generates power to drive the sprocket to rotate.

[0028] Specifically, there are two swinging mechanisms 2, which are respectively conveyed from two bookbinding lines and are respectively arranged in the upstream book entry direction of at least the first notebook conveying mechanism 11 and the second notebook conveying mechanism 12.

[0029] As Figure 3 shown in the figure, the swinging mechanism 2 includes support plates 21 arranged on both sides of the conveying support, a connecting shaft 23 rotatably fixed between the support plates 21, a first swing arm 24 fixed at one end of the connecting shaft 23, a joint bearing 25 connected to the first swing arm 24, and a swinging power unit 26 connected to the joint bearing 25. At least two parallel second swing arms 22 are fixed on the connecting shaft 23, and a swinging plate 27 is fixed on the second swing arms 22. A notebook backing plate 3 is fixed obliquely upward on the support plates 21. A movable baffle 6 is installed on one side of the notebook backing plate 3, and a photoelectric switch 4 is provided on the other side of the notebook backing plate 3. The swinging plate 27 is arranged on the lower side of the bottom of the notebook backing plate 3. Inclined fixing guide plates 5 are provided between the swinging plate 27 and the first notebook conveying mechanism 11 and the second notebook conveying mechanism 12 respectively.

[0030] A baffle 6 is installed on the notebook backboard 3, which can be a movable angle aluminum to limit the stopping position of the notebook. The angle aluminum can be adjusted according to the length of the notebook. Preferably, a first long slot parallel to the entry direction of the notebook is provided at a position close to one side of the notebook backboard 3, and the baffle 6 is fixed in front of the first long slot by a fastening bolt. A second long slot parallel to the entry direction of the notebook is provided at a position close to the other side of the notebook backboard 3, and the photoelectric switch 4 is fixed behind the second long slot by a fastening bolt. It should be noted that the front side in the present invention refers to the surface where the notebook is located, and the rear side refers to the back of the surface where the notebook is located.

[0031] Preferably, the swing power unit 26 includes a cylinder, a hydraulic pressure, or an eccentric wheel, a cam, a motor, or a swing rod. In the present invention, the swing power unit 26 can be one of the above-mentioned various forms, and any device that can provide a power to enable the spherical plain bearing 25 to perform up-and-down reciprocating motion can be used as the swing power unit 26 in the present invention.

[0032] A long slot is opened on the edge of the notebook backboard 3, and the photoelectric switch 4 is installed below the notebook backboard 3 to detect whether the notebook passes through and control the action of the swing cylinder through the second long slot, thereby controlling the swing of the swing plate. A swing plate 27 is installed on the lower side of the notebook backboard. The swing plate 27 is installed on three second swing arms 22. When the swing plate 27 is stationary, it supports the lower side of the notebook to prevent the notebook from tilting and falling off. Below the guide plate 5 is the conveyor belt.

[0033] Preferably, the swing plate 27 is located on the lower side of the notebook backboard 3; when the swing mechanism 2 works, the swing plate 27 swings with the connecting shaft 23 as the rotation axis, and when the connecting shaft 23 swings, the maximum angle between the swing plate 27 and the notebook backboard 3 is greater than 90°. To facilitate the falling of the notebook, the maximum angle between the swing plate 27 and the notebook backboard 3 can be set to be close to 180°. The swing plate 27 is installed on three second swing arms 22. The three second swing arms 22 are fixed on the connecting shaft 23. The connecting shaft 23 is installed on the support plate 21. A first swing arm 24 is installed at one end of the connecting shaft 23 outside the support plate 21. The first swing arm 24 is connected to the swing power unit 26 through a spherical plain bearing 25. When the swing power unit 26 acts, it drives the first swing arm 24 to swing. The first swing arm 24 drives the connecting shaft 23 to rotate. The rotation of the connecting shaft 23 drives the second swing arms 22 to swing, and the second swing arms 22 drive the swing plate 27 to swing.

[0034] Preferably, the distance between the photoelectric switch 4 and the baffle 6 is matched with the specification of the notebook. When the photoelectric switch 4 detects that the notebook is in contact with the baffle 6, the signal of the photoelectric switch 4 controls the swing mechanism 2 to act, and controls the notebook to slide from the swing plate 27 to the first conveyor belt 114 and the second conveyor belt 124 through the guide plate 5.

[0035] When the combined conveying device for the double-back binding line of notebooks of the present invention is working, the notebooks that have been glued on the two gluing lines enter the notebook backing plate in sequence. When the photoelectric switch just detects that the notebook enters the notebook backing plate, the swing power unit does not act, the swing plate does not swing, and it supports the lower side of the notebook to prevent the notebook from tilting and falling off. When one end of the notebook leans against the angle aluminum position, the other end just exposes the photoelectric switch. At this time, the photoelectric switch controls the swing cylinder to work, driving the first swing arm to swing. The first swing arm drives the connecting shaft to rotate, and the connecting shaft drives the second swing arm and the swing plate to swing, so that there is no support on the lower side of the notebook. In this way, the notebook falls onto the conveyor belt through the guide plate and is finally conveyed to the cutting mechanism for cutting.

[0036] Further, the notebooks in the upstream direction enter the first conveyor belt 114 through the lower side of the guide plate 5 after passing through the second conveyor belt 124, so that the notebooks that have been glued on the two gluing lines are combined and conveyed to the subsequent cutting mechanism.

[0037] The combined conveying device for the double-back binding line of notebooks of the present invention can make the speeds of printing, gluing, and cutting match, thus realizing a high-speed fully automatic production line from the web to the notebook (i.e., from the raw material to the product). The speed is doubled compared with the original production line, and the fastest speed can reach 50 pieces per minute or even higher.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: still can modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
