Abstract
Description
Technical Field
[0001] This utility model relates to the field of book technology, and in particular to a buffer drop frame for book packaging. Background Technology
[0002] After being wrapped in protective film, each book is conveyed to the stacking station via a conveyor belt. Once a certain number are stacked, they are transferred to the packaging area where the stacked books are packaged together. During this process, a drop frame is installed at the stacking station to control the stacking direction of books falling from the conveyor belt.
[0003] For example, a plastic sealing machine proposed in utility model patent application number CN202222552426.0 has a receiving plate for placing hardcover books at the end of the book receiving belt away from the conveyor belt, and a guide plate is inclined at the end of the book receiving belt away from the conveyor belt, with the end of the guide plate near the receiving plate being the inclined lower end.
[0004] However, since the books fall directly onto the receiving plate, if a large number of books are stacked at once, the lower layer of books may fall from a greater height, causing them to bounce and tilt, resulting in jamming and affecting the falling process of subsequent books. Utility Model Content
[0005] In view of this, it is necessary to provide a cushioning drop frame for book packaging to solve the problem that if the books fall from a great height, they are prone to bounce and tilt, causing jamming and affecting the subsequent falling process of the books.
[0006] This utility model provides a buffer drop frame for book packaging, including a drop frame and a limiting component. The drop frame has a stacking cavity extending vertically, and the bottom side wall of the drop frame has a discharge port communicating with the stacking cavity. The limiting component is connected to the drop frame and has a limiting end that can move to a position inside the drop frame to divide the stacking cavity into a first cavity and a second cavity arranged vertically upwards. The limiting end can also move to a position outside the drop frame.
[0007] Furthermore, the limiting component includes a limiting plate, a sliding groove is provided on one side of the falling frame, and a slot is provided on the inner wall of the other side of the falling frame, and the sliding path of the limiting plate passes through the sliding groove and the slot.
[0008] Furthermore, the height of the first cavity is twice the height of the second cavity, and the height of the first cavity is equal to the height of the discharge port.
[0009] Furthermore, the limiting component also includes a driving member, which is mounted on the side wall of the falling frame. The output end of the driving member is connected to the portion of the limiting plate located outside the falling frame, and is used to drive the limiting plate to slide.
[0010] Furthermore, the driving component is a telescopic cylinder, and the limiting assembly also includes a connecting rod and a support plate. The output shaft of the telescopic cylinder is fixedly connected to the bottom of the limiting plate via the connecting rod, and the telescopic cylinder is fixedly connected to the side wall of the falling frame via the support plate.
[0011] Furthermore, it also includes a buffer component, which is disposed within the limiting frame to buffer books falling within the limiting frame.
[0012] Furthermore, the buffer assembly includes multiple brushes, each of which is disposed in a plurality of mounting slots opened on the inner wall of the drop frame. The multiple brushes extend vertically, and the free ends of the multiple brushes extend outside the mounting slots.
[0013] Furthermore, it also includes a base, on which the drop frame is mounted, and the buffer assembly further includes a buffer pad, which is fixedly disposed on the base and located within the drop frame.
[0014] Furthermore, it also includes a movable door assembly, which is disposed at the discharge port of the falling frame. The movable door assembly can be moved to a position offset from the discharge port or to a position that partially blocks the discharge port.
[0015] Furthermore, the movable door assembly includes two door panels and two rotating members. The two door panels are rotatably connected to the portions of the drop frame located on both sides of its discharge port. The two rotating members are mounted on the side wall of the drop frame and are slidably hinged to the two door panels respectively, for driving the two door panels to rotate.
[0016] Compared with existing technologies, books conveyed by a conveyor belt fall into the stacking cavity from above the drop frame. First, the limiting end of the limiting component moves into the drop frame. At this time, the books fall into the second cavity. After a certain number are stacked, the limiting end moves out of the drop frame, and the books fall from the second cavity to the first cavity. Subsequent books fall directly onto the stacked books in the second and first cavities. This can effectively reduce the falling height of each book and effectively prevent the books from bouncing and tilting due to a large falling height. Attached Figure Description

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0023] like Figure 1-2 As shown, the present invention provides a buffer drop frame for book packaging, including a drop frame 100 and a limiting component 200. The drop frame 100 has a stacking cavity extending vertically, and the bottom side wall of the drop frame 100 has a discharge port 110 communicating with the stacking cavity. The limiting component 200 is connected to the drop frame 100 and has a limiting end. The limiting end can move to a position inside the drop frame 100 to divide the stacking cavity into a first cavity and a second cavity arranged vertically upwards. The limiting end can also move to a position outside the drop frame 100.
[0024] During implementation, books conveyed by the conveyor belt fall into the stacking cavity from above the drop frame 100. First, the limiting end of the limiting component 200 moves into the drop frame 100. At this time, the books fall into the second cavity. After a certain number are stacked, the limiting end moves out of the drop frame 100, and the books fall from the second cavity into the first cavity. Subsequent books fall directly onto the stacked books in the second and first cavities. This can effectively reduce the falling height of each book and effectively prevent the books from falling too high, causing them to bounce and tilt.
[0025] In this embodiment, a stacking cavity extending vertically is formed inside the drop frame 100, and a discharge port 110 communicating with the stacking cavity is provided on the side wall at the bottom of the drop frame 100.
[0026] The limiting component 200 in this embodiment is used to reduce the falling height of each book.
[0027] like Figure 2-3As shown, in one embodiment, the limiting component 200 includes a limiting plate 210, a sliding groove 120 is provided on one side of the falling frame 100, and a slot 130 is provided on the inner wall of the other side of the falling frame 100. The sliding path of the limiting plate 210 passes through the sliding groove 120 and the slot 130.
[0028] In one embodiment, the height of the first cavity is twice the height of the second cavity, and the height of the first cavity is equal to the height of the discharge port 110. For example, if six books need to be stacked, when the limiting plate 210 moves into the drop frame 100, three books can be stacked in the second cavity first, and then the limiting plate 210 is moved outside the drop frame 100, so that the three stacked books in the second cavity fall into the first cavity, and the subsequent books can fall directly into the drop frame 100.
[0029] like Figure 4 As shown, in order to facilitate the sliding of the limiting plate 210, in one embodiment, the limiting component 200 further includes a driving member 220. The driving member 220 is installed on the side wall of the falling frame 100. The output end of the driving member 220 is connected to the part of the limiting plate 210 located outside the falling frame 100, and is used to drive the limiting plate 210 to slide.
[0030] The driving component 220 is a telescopic cylinder, and the limiting component 200 also includes a connecting rod 221 and a support plate 222. The output shaft of the telescopic cylinder is fixedly connected to the bottom of the limiting plate 210 via the connecting rod 221, and the telescopic cylinder is fixedly connected to the side wall of the falling frame 100 via the support plate 222.
[0031] To further prevent books within the falling frame 100 from bouncing, this embodiment also includes a buffer component 300, which is disposed within the limiting frame to buffer the books falling within the limiting frame.
[0032] like Figure 1 and Figure 5 As shown, in one embodiment, the buffer assembly 300 includes a plurality of brushes 310, which are respectively disposed in a plurality of mounting slots opened on the inner wall of the drop frame 100. The plurality of brushes 310 extend in a vertical direction and the free ends of the plurality of brushes 310 extend outside the mounting slots.
[0033] In one embodiment, the system further includes a base 140, on which the drop frame 100 is mounted, and the buffer assembly 300 further includes a buffer pad 320, which is fixedly disposed on the base 140 and located within the drop frame 100.
[0034] To prevent books from passing through the discharge port 110 when stacking books and affecting the stacking effect, this embodiment also includes a movable door assembly 400. The movable door assembly 400 is located at the discharge port 110 of the lower frame 100. The movable door assembly 400 can be moved to a position offset from the discharge port 110 or to a position that blocks part of the discharge port 110.
[0035] In one embodiment, the movable door assembly 400 includes two door panels 410 and two rotating members 420. The two door panels 410 are rotatably connected to the portions of the drop frame 100 located on both sides of its discharge port 110. The two rotating members 420 are mounted on the side wall of the drop frame 100 and are slidably hinged to the two door panels 410, respectively, for driving the two door panels 410 to rotate. Each rotating member 420 includes a cylinder, which is fixedly mounted on the side wall of the drop frame 100. A slider is hinged to the output end of the cylinder, and the slider is slidably connected to the door panel 410.
[0036] Compared with existing technologies: Books conveyed by the conveyor belt fall into the stacking cavity from above the drop frame 100. First, the limiting end of the limiting component 200 moves into the drop frame 100. At this time, the books fall into the second cavity. After a certain number are stacked, the limiting end moves out of the drop frame 100, and the books fall from the second cavity to the first cavity. Subsequent books fall directly onto the stacked books in the second and first cavities. This can effectively reduce the falling height of each book and effectively prevent the books from falling too high, causing them to bounce and tilt.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
