Description

Technical Field

[0001] The utility model relates to a paging and posting mechanism and a paging machine. Background Art

[0002] In printing enterprises, book binding generally adopts the matching method to produce various paperback books, hardcover books and picture albums, and books with perfect binding. Matching method: It is to stack the books one by one in the order of their page numbers to make them the book core of a book. The working principle of the matching page collating machine: the books to be matched are placed in the page storage box of the collating machine in the order of their page numbers. When the machine moves, the paging device under the book stack absorbs the bottom book in the page storage box and transmits it downward into the lever. The lever pushes the book forward. After a book core is matched, it enters the binding machine for the next process or is collected by the collecting device.

[0003] The existing paging and posting mechanisms of the paging machine include single-gripping rollers, double-gripping rollers and vise-type swing arms. The posting direction of these paging and posting mechanisms is perpendicular to the movement direction of the lever, which means that the speed of the book sticker entering the lever in the initial position in the direction of the lever movement is zero, and the book sticker is easily uneven due to the impact of the lever on the pallet channel. In addition, the page mouth extracts the book sticker from the bottom layer of the page storage box filled with paper piles. At this time, the book sticker at the bottom layer is still under pressure from the other book stickers in the storage box, and it is more difficult to pull the book sticker at the bottom layer at the page mouth, which easily causes the page mouth to be disconnected from the book sticker and produce wrinkles on the book sticker. Therefore, the page storage box is not allowed to load a large number of book stickers, and personnel need to frequently change the paper pile, which increases the work intensity of personnel. In addition, the page mouth of the paging and posting mechanism of the existing paging machine is worn out due to the high frequency of use over time, and the page mouth will not bite the book sticker stably, causing posting failure. In general, the existing paging and posting mechanism of the paging and posting machine does not use separate servo motors for the paging and posting modules, which limits the further improvement of the paging efficiency, and the paging effect on thin sheets such as single sheets and folded pages is not ideal.

[0036] This embodiment 1 is as Figure 1 As shown: This embodiment is a horizontal pagination machine, which adopts a linear negative pressure belt pagination and posting mechanism. Multiple groups of pagination and posting mechanisms 1 are installed on the frame in sequence. The initial speed of the book signature 100 entering the lever matches the lever speed. Figure 1 The 10 in the middle refers to the direction of movement of the lever, which has a significant effect on the collating of single sheets, folded pages and multiple folded pages. The paging and posting mechanism of this collating machine has a fast collating speed, small mechanical inertia impact and high collating quality. Compared with the clamp-type collating machine and the roller-type collating machine, a new type of paging and posting mechanism has revolutionary significance, breaking through the limitation of the difficulty of collating and posting thin sheets such as single sheets and folded pages. The mechanism has a lower failure rate of paper jams, over-posting and under-posting, higher efficiency and lower energy consumption.

[0037] In this embodiment, the paging and posting mechanism uses a cam mechanism and a belt transmission for paging and posting. The power source of the paging and posting mechanism is provided by an independent motor, and it can use both a 1:1 posting mode and a 1:2 posting mode. The 1:1 posting mode means that the movement rhythm of the lever is consistent with the posting rhythm of the paging and posting mechanism of a workstation. When a workstation works in one cycle, the lever moves a lever spacing, and the content of the book stickers assigned to each workstation is different. The 1:2 posting mode means that the book stickers assigned to two adjacent workstations have the same content, and the stickers are respectively assigned to two adjacent levers. At this time, the movement rhythm of the paging will be half of the movement rhythm of the lever, and the posting speed of the book stickers will still match the lever speed, which is more conducive to the deceleration of the paging action to execute related actions, improve the accuracy and stability of posting, and solve the problem of difficulty in paging single sheets and folded pages.

[0038] As attached Figure 1 As shown, the paging and dispensing mechanisms 1 are arranged linearly on the frame of the collating machine, and the upper and lower belt directions of the paging and dispensing mechanisms 1 are consistent with the movement direction of the lever 10. The book signature 100 is pushed forward by the lever on the pallet channel of the collating machine, and the book signature that enters the lever position later is stacked on the previous book signature. The book signatures on the paging and dispensing mechanisms 1 enter the lever position in turn through the spiral dispensing to form a book core.

The various parts of the rack are connected by screws and various standard connections, and the overall rack structure is stable.

[0041] The paging camshaft assembly 22 is as follows Figure 5 and Figure 6 As shown, it mainly consists of a synchronous wheel expansion sleeve 2201, a synchronous wheel 2202, a spindle spacer 2203, a rotating spindle 2204, a ring 2205, a proximity switch 2206, a spindle support frame 2207, a conjugate cam 2208, a cam I 2209, a cam spacer 2210, a cam II 2211, a left groove cam 2212, a groove cam spacer 2213, a right groove cam 2214 and a spindle mounting flange 2215. The cam I 2209 acts on a negative pressure mechanical valve 29. The mechanical valve is as shown in FIG. Fig.15 and Fig.16 The mechanical valve shown controls the timing of the suction nozzle sucking pages; the cam II 2211 acts on the positive pressure mechanical valve 2407 to control the paging timing of the blowing nozzle, the blowing timing of the open belt and the blowing timing of the receiving box side; the left groove cam 2212 and the right groove cam 2214 act on the swing arm 2401 in the suction nozzle and blowing nozzle paging assembly 24, thereby controlling the suction nozzle to suck the page and pull it down, cooperate with the blowing nozzle to blow air and insert the page into the inside to perform paging, so as to put the book stickers in order.

[0042] The leaf storage device 23 is as follows Figure 7 and Figure 8As shown in the figure, it mainly consists of four book label side positioning plates 2301, a perforated belt 2302, a belt support plate 2303, a driven roller 3404, a driving roller 2305, a slide rail 2306, a specification adjustment slider 2307, etc. The transmission power of the perforated belt 2302 comes from the paging transmission component 27, which is controlled by a separate servo motor 2704. The servo motor 2704 rotates the conjugate cam 2208 on the core shaft 2204 through the paging synchronous belt 2205, and transmits the force through the connecting rod mechanism, controlling the reciprocating motion of the perforated belt 2303, so that the paginated book labels are transported forward along the lever.

[0043] The nozzle and blowing nozzle paging assembly 24 is as shown in FIG. Fig. 9 As shown: it mainly consists of a swing arm 2401, a pull rod I 2402, an air blowing swing block fixing block 2403, an air blowing duckbill tube 2404, an air suction right mounting plate 2405, an air suction left mounting plate 2406, a positive pressure mechanical valve 2407, a label separation suction nozzle 2408, and a pull rod II 2409; the air blowing duckbill tube 2404 swings up and down around the fulcrum, and the label separation suction nozzle 2408 swings up and down around the fulcrum. When the label separation suction nozzle 2408 approaches the book label, the negative pressure mechanical valve conducts negative pressure to act on the suction nozzle, and then the book label will be sucked by the label separation suction nozzle 2408, and then pulled down for paging, and the air blowing duckbill tube 2404 is inserted into the upper surface of the bottom label to separate the book label pile; the function of the suction nozzle and the air blowing nozzle paging assembly 24 is to separate the bottom label from the book label pile and separate it, so that the perforated belt can accurately vacuum absorb and transport the bottom label, so that the second layer of the label will not be brought out to form a multiple label fault.

[0044] Front pressure wheel assembly 25 as Fig.10 and Fig. 10A As shown, it mainly consists of important components such as a book label transmission shaft 2501, a right side pressing wheel 2502, a thickness measuring pressing wheel 2503, a pressing wheel rotating mandrel 2504, a left side pressing wheel 2505, a cylinder 2506, a thickness measuring pressing wheel swing arm 2507, a right side pressing wheel swing arm 2508, and a pressing wheel position adjustment block 2509. The bottom book label is transported forward by vacuum adsorption of the perforated belt 2303 and reaches the front pressing wheel assembly 25. The book label transmission shaft 2501 continues to transport the right side pressing wheel 2502 and the left side pressing wheel 2505 downward. The power comes from the cylinder 2506; the book label passes through the thickness measuring pressing wheel 2503, and the thickness measuring pressing wheel swing arm 2507 is forced to lift up, which can detect the thickness change of the book label to prevent the book label from being too little or too much. The pressing wheel position adjustment block 2509 can mainly control the position of the right side pressing wheel 2502, which is easy to adjust and is used to adapt to book labels of different specifications.

[0045] Upper and lower belt lower post assembly 26 as Fig.11 and Fig.12As shown in the figure, it mainly consists of a book label lower sliding plate 2601, an upper belt front roller 2602, an upper belt rear roller 2603, an upper belt 2604, a lower belt front roller 2605, a lower belt 2606, a lower belt rear roller 2607, an upper belt pressing plate 2608, etc. After the book label is transmitted by the front pressing wheel assembly 25, it enters between the upper belt 2604 and the lower belt 2606, and is clamped by the upper belt 2604 and the lower belt 2606 along the book label lower sliding plate 2601 into the lever channel, and then the lever pushes the book label to be transported forward. The power of the upper belt 2604 and the lower belt 2606 of the upper and lower belt lower label assembly 26 comes from the lower label transmission assembly 27.

[0046] Paging transmission assembly 27 Fig.13 As shown, the paging transmission component 27 mainly includes a paging active synchronous wheel 2701, a paging driven synchronous wheel 2702, a paging tensioning wheel 2703, a paging servo motor 2704 and a paging synchronous belt 2705; the paging transmission component 27 controls the paging cam shaft component 22, completes the paging suction nozzle 2408 sucking the book, the blowing duckbill tube 2404 inserts the bottom book and then blows, and provides power for the perforated belt 2302, etc., to realize the paging function.

[0047] The transmission assembly 28 is as follows: Fig.14 As shown, it mainly includes a lower post active synchronous wheel 2801, a lower post driven synchronous wheel 2802, a lower post tensioning wheel 2803, a lower post servo motor 2804 and a lower post synchronous belt 2805. The lower post driven synchronous wheel 2802 is connected to the book sticker transmission shaft 2501, driving the book sticker to be transported forward, and also provides a power source for the upper belt 2604 and the lower belt 2606 of the upper and lower belt lower sticker assembly 26, completing the action of the book sticker entering the book shifting channel, and finally being transported forward by the shifting rod.

[0048] The negative pressure mechanical valve used in this embodiment is as follows Fig.15 and Fig.16 As shown, the negative pressure mechanical valve 11 is mainly composed of a negative pressure slider 2901, a negative pressure slide 2902, a spring 2903, a spring pressure plate 2904, a negative pressure air nozzle 2905, a pressure cover 2906, a bearing 2907 and other parts. A vent hole is provided on the negative pressure slider 2901, and the bearing 2907 of the negative pressure mechanical valve is in contact with the cam I 2209. When the core shaft 2204 rotates, the cam I 2209 controls the on and off of the negative pressure air nozzle 2905, acting on the open hole belt 2303.

[0049] In this embodiment, the various components are interconnected and cooperate with each other to achieve the separation and transmission of at least one book label, and continuous and efficient paging in one cycle and one beat. The vacuum adsorption linear paging and paging mechanism reduces the resistance to the book labels during paging, thereby improving the working efficiency of the paging machine.

[0050] In the collating machine of this embodiment, the bookmarks are manually placed in the storage and accommodating device 23 composed of four side positioning plates 2301 to achieve the storage of the paper pile. The perforated belt 2303 supports most of the paper pile, and one side of the bookmark is exposed outside the edge of the negative pressure belt. The power of the paging mechanism 27 of the paging and posting mechanism is preferably a servo motor. The paging servo motor 2704 provides power for the core shaft 2204 in the paging cam shaft mechanism 22 of the paging and posting mechanism. The conjugate cam 2208 in the paging cam shaft mechanism 22 drives the swing arm to drive the active roller 2305 in the page storage box 23, and the perforated belt 2302 makes reciprocating motion to absorb the bottommost book label and transport it forward to the front pressure wheel assembly 25. The curved surface of the cam I 2209 in the paging cam shaft mechanism 22 contacts the bearing 2907 of the negative pressure mechanical valve. The negative pressure slider 2901 in the negative pressure mechanical valve slides in the negative pressure chute 2902, turning on or off the negative pressure of the negative pressure air nozzle 2905, and then sequentially supplies the negative pressure of the perforated belt 2302 and the paging and posting suction nozzle 2408. When the paging and posting mechanism is working, the negative pressure of the perforated belt 2302 acts on the bottommost book label, and the force acting surface is large, which is conducive to protecting the book label from being damaged.

[0051] The suction nozzle and blowing nozzle paging assembly 24 is arranged on the side of the perforated belt edge of the page storage and accommodating device 23, so that the paging nozzle can separate the bottommost book label of the paper stack from the paper stack and the paging nozzle can lift and support the rest of the book labels, and blow air to reduce the friction force of pulling out the bottommost book label. The right groove cam 2214 of the paging cam shaft mechanism 22 drives the swing arm 2401, and links the pull rod I 2402, so that the paging nozzle 2408 swings up and down around the fulcrum, and the paging nozzle 2408 conducts negative pressure to suck the bottommost book label of the book label stack, and the paging nozzle 2408 is pulled downward around the fulcrum. At this time, there is a V-shaped opening between the bottommost book label and the upper book label. The left groove cam 2212 of the paging cam shaft mechanism 22 drives the swing arm 2401, and links the pull rod II 2409, so that the air blowing duckbill tube 2404 swings up and down around the fulcrum, and the air blowing duckbill tube 2404 is inserted into the V-shaped opening formed by the bottom book label and the upper book label, separating the bottom book label, and lifting the rest of the book labels, and conducting positive pressure blowing to reduce the resistance of the perforated belt 2302 in the process of extracting the bottom book label, and completing the book label paging action. The cam II2211 acts on the positive pressure mechanical valve 2407, conducting or closing the positive pressure, and then respectively controlling the blowing timing of the air blowing duckbill tube, the blowing timing of the perforated belt and the blowing timing of the receiving box side, which are all conducive to improving the stability of the lower label.

[0052] The book label is adsorbed by the perforated belt and transmitted forward to the front pressure wheel assembly 25, and then enters the upper and lower belt lower post assembly 26 through the right pressure wheel 2502 and the left pressure wheel 2505 meshing with the transmission shaft 2501. The book label passes through the thickness measuring pressure wheel 2503, and the thickness measuring pressure wheel swing arm 2507 is forced to lift, which can detect the thickness change of the book label and prevent the book label from being less or more. After the book label is transmitted by the upper pressure wheel assembly, it enters between the upper belt 2604 and the lower belt 2606, and is clamped by the upper belt 2604 and the lower belt 2506 along the sliding deck 2601 of the book label to enter the lever channel, and then the lever pushes the book label to be transported forward. The common power of the front pressure wheel assembly 25 and the upper and lower belt lower post assembly 26 comes from the lower post servo motor 2804 of the lower post transmission assembly 28. The upper and lower belts clamp the book labels and convey them forward. The running direction of the book labels is consistent with the running direction of the lever 10. The speed of the upper and lower belts matches the speed of the lever to ensure smooth handover of the book labels and reduce collision of the book labels caused by speed difference.

[0053] In this embodiment, the components are interconnected and cooperate with each other. The core shaft 2204 rotates one circle to separate a book label, and the paging is continuous and efficient. The running direction of the book label is consistent with the running direction of the lever, and the speed of the upper and lower belts matches the speed of the lever. The vacuum adsorption linear paging mechanism reduces the resistance of the book label during paging, thereby improving the working efficiency of the paging machine.

[0054] The paging and posting mechanism of the collating machine in this embodiment adopts shaftless transmission control technology. The power of the lever of the collating machine comes from an independent motor. The paging cam shaft of each station of the collating machine is driven by an independent servo motor. The posting conveying belt of each station of the collating machine is driven by an independent servo motor. Therefore, a shaftless transmission control technology is proposed to be applied to the collating machine. The paging and posting mechanism of the collating machine can use both the 1:1 posting mode and the 1:2 posting mode. In general, a new type of paging and posting mechanism provides three working modes: first, the working beat of all collating machine stations corresponds to the running beat of the lever in a 1:1 manner, which is called the 1:1 posting working mode, and the working efficiency is high. Second, the working beat of all collating machine stations corresponds to the running beat of the lever in a 1:2 manner, which is called the 1:2 posting working mode. The 1:2 posting mode means that the book posts of two adjacent stations have the same content, and the posts are respectively posted to the two adjacent levers. At this time, the movement beat of the paging will be half of the movement beat of the lever, which is more conducive to the speed reduction of the paging action to execute related actions. Third, the working rhythm of two adjacent workstations corresponds to the running rhythm of the lever at a ratio of 1:2, and the working rhythm of the other workstations corresponds to the running rhythm of the lever at a ratio of 1:1, which is called the combined posting working mode, which combines the advantages of the previous two working modes and solves the problem of difficulty in collating single sheets and folded pages. Regardless of the 1:1 posting mode or the 1:2 posting mode, the forward movement of the book label is consistent with the movement direction of the lever, and the speed matches, which avoids the impact caused by the mismatch between the speed of the book label and the lever, which affects the neatness of the book core.
