Description

Technical Field

[0002] In the related art, in the process of automatic printing of multi-page printed materials such as certificates, photo albums, certificates, etc., how to efficiently and orderly convey the multi-page printed materials has become an urgent problem to be solved. The traditional method of conveying multi-page printed materials often relies on manual stacking, fixing and taking away. This method is not only inefficient, but also prone to errors. Especially when dealing with a large number of multi-page printed materials, manual operation can easily lead to problems such as damage to the multi-page printed materials and disordered sorting. In the related art, multi-page printed materials are automatically conveyed for printing through a conveying mechanism, but as the spring that compresses the multi-page printed materials during the conveying process will gradually reduce the pressure, it will cause the opening side of the multi-page printed materials to spread out, loosen, overturn, and even cause the conveying device to jam, which is not conducive to use. Summary of the invention

[0023] Reference Figures 1 to 8The present invention proposes a conveying mechanism, including a frame 100, a collection box 200, a book pushing device 300 and an extrusion assembly 400. Specifically, the stable frame 100 serves as the foundation of the entire conveying mechanism to support the entire conveying mechanism. Optionally, a support leg is provided at the bottom of the frame 100 to improve the overall stability of the conveying mechanism. Further, the collection box 200 is connected to the frame 100, and is provided with a receiving slot 210 for receiving a multi-page printed material 600. One or more multi-page printed materials 600 can be placed in the receiving slot 210. The multi-page printed material 600 can be placed vertically, inclined, etc. The opening side of the multi-page printed material 600 can be located at the bottom, or on the left or right side. The following is an example in which the multi-page printed material 600 is stacked vertically and the opening side faces downward. A baffle is provided at the output end of the receiving slot 210 to limit the movement of the multi-page printed material 600 in the receiving slot 210. A guide member 220 is disposed in the receiving groove 210 , and the guide member 220 is used to guide the movement of the pushing device 300 .

[0024] Furthermore, the book pushing device 300 is connected to the book collection box 200 and is located in the accommodating groove 210. The book pushing device 300 includes a book pressing component 310 and a pressure compensation component 320. The book pressing component 310 includes a base 311 and a pressure plate 313. The pressure plate 313 is connected to a mounting seat 312. The mounting seat 312 and the base 311 are slidably connected to the guide member 220. The mounting seat 312 is located between the base 311 and the baffle. A spring 314 is provided between the base 311 and the mounting seat 312. The spring 314 is compressed and pushes the pressure plate 313 toward the baffle. The mounting seat 312 and the pressure plate 313 are pushed toward the baffle by their elastic force, thereby pressing and pushing the multi-page printed material 600 placed in the accommodating groove 210. The pressure compensation component 320 is connected to the base 311 to drive the book pressing component 310 to apply constant pressure to the multi-page printed material 600. When the pressure between the pressure plate 313 and the multi-page printed material 600 deviates from the preset value due to the use of the multi-page printed material 600, the pressure compensation component 320 will automatically adjust the output force, adjust the relative position distance between the pressure component 310 and the multi-page printed material 600, ensure that the compression amount of the spring 314 between the base 311 and the mounting seat 312 is constant, and thereby ensure that the pressure plate 313 applies a constant and moderate pressure to the multi-page printed material 600.

[0025] Further, the pressing assembly 400 is connected to the book collection box 200, and the pressing assembly 400 includes a first driving member 410 and a pressing belt 420. The first driving member 410 is used to drive the pressing belt to move. The pressing belt 420 is provided with a horizontal pressing section 421. The pressing section 421 is located at the bottom wall of the receiving groove 210 and contacts the opening side of the multi-page printed material 600 to keep the multi-page printed material 600 in a closed state. It should be understood that the pressing section 421 is determined according to the placement state of the multi-page printed material 600, and can be any wall of the receiving groove 210. During the conveying process, the pressing belt 420 moves synchronously with the movement of the multi-page printed material 600, and the multi-page printed material 600 is firmly fixed in the receiving groove 210 through its friction force, further preventing the opening side of the multi-page printed material 600 from spreading, and ensuring that the multi-page printed material 600 always remains closed and orderly arranged during the conveying process.

[0026] It is understandable that the combination of the pressing assembly 310 and the pressure compensation assembly 320 can push the multi-page printed material 600 while ensuring that the pressing plate 313 applies a constant and appropriate pressing force to the multi-page printed material 600, effectively preventing the multi-page printed material 600 from being loose or overturned during the conveying process, and ensuring the stability and reliability of the conveying. The squeezing assembly 400 further enhances the stability of the multi-page printed material 600 during the conveying process, avoids the opening side from spreading due to the reduction of pressure, and uses the squeezing belt 420 to drive the multi-page printed material to maintain a closed state.

[0027] Reference Figure 3 and Figure 4 In some embodiments, the driving member includes a first motor 411, a first driving wheel 412 and two first driven wheels 413. The first motor 411 serves as a power source and drives the first driving wheel 412 to rotate through a transmission device. The transmission device can be a gear or a chain, etc. The two first driven wheels 413 are arranged along the length direction of the collection box 200 and are located at the bottom of the accommodating groove 210 to ensure that the extrusion belt 420 can smoothly run around the driving wheel and the two driven wheels. The extrusion belt 420 is a closed-loop structure, and its material should have certain flexibility and wear resistance to withstand friction and tension in long-term operation. The extrusion section 421 is located between the two driven wheels and directly acts on the bottom of the multi-page printed material 600. The friction force of the belt 3214 maintains the closed state of the multi-page printed material 600 and pushes it forward. It should be noted that the squeezing section 421 can be set at the bottom of the collection box 200 or at the side. According to the placement of the multi-page printed matter 600, the squeezing section 421 is preferably in contact with the open end of the multi-page printed matter 600.

[0028] Furthermore, in some embodiments, the bottom wall or side wall of the collection box 200 is provided with a clearance gap 212. The clearance gap 212 is in the shape of an elongated strip, and its position and size are determined by the running track of the extrusion belt 420 and the arrangement of the driven wheel, and it is preferably able to accommodate the extrusion section 421. The two driven wheels are respectively installed at both ends of the clearance gap 212 to prevent interference with the extrusion belt 420. At the same time, the first motor 411 is installed below the accommodating groove 210 and is connected to the driving wheel, which saves space and ensures stable power transmission. The provision of the clearance gap 212 avoids the contact area between the extrusion belt 420 and the bottom wall of the collection box 200, reduces the friction resistance during operation, prolongs the service life of the belt 3214, and also reduces the risk of failure due to interference or collision between components, thereby improving the operational reliability and stability of the entire conveying mechanism.

[0029] Reference Figure 1 , Figure 5 and Figure 6 In order to prevent the multi-page printed matter 600 from retreating due to inertia or external force during the conveying process, in some embodiments, the collection box 200 is further provided with an anti-return assembly 500, and the anti-return assembly 500 is located between the extrusion assembly 400 and the book pushing device 300. Specifically, the anti-return assembly 500 includes a mounting frame 510 and a plurality of anti-return blocks 520. The mounting frame 510 is fixed in the collection box 200, and is provided with an elongated mounting groove 511. The plurality of anti-return blocks 520 are arranged in a single row in the mounting groove 511, and are connected to the mounting frame 510 through a rotating shaft 521. An anti-return spring 512314 is installed between the anti-return block 520 and the mounting frame 510, so that the movable end of the anti-return block 520 always protrudes out of the mounting groove 511 under the action of the spring 314. In order to limit the anti-return block 520 from excessively rotating in the direction of the book pushing device 300, a limiting member 513 is also provided on the mounting frame 510. When the multi-page printed material 600 is pushed forward, its bottom will contact the movable end of the stop block 520 and push it to rotate. When the multi-page printed material 600 attempts to retreat, the stop block 520 quickly resets under the force of the spring 314 and blocks the retreat path of the multi-page printed material 600.

[0030] It should be noted that in some embodiments, the limit member 513 is a limit rod passed through the stop block 520, and the mounting frame 510 is provided with a limit hole, and the limit rod is provided through the limit hole. When the multi-page printed material 600 retreats and abuts against the stop block 520, the limit rod abuts against the side wall of the limit hole to limit the stop block 520 from moving toward the side of the push device 300, thereby limiting the retreat of the multi-page printed material 600.

[0031] In other embodiments, the stopper 513 can be arranged above the elongated mounting groove 511 of the mounting frame 510, and a row of blocking blocks can be arranged along the length direction thereof. These blocking blocks can be small blocks or protrusions that are fixedly installed, and the material can be the same metal or other hard material as the mounting frame 510 to ensure its stability and durability. The specific shape and size of the blocking blocks can be adjusted according to the stop block 520 to ensure that they can effectively limit the rotation range of the stop block 520, so that when the multi-page printed material 600 is pushed forward, it is easier to pass the movable end of the stop block 520, and when the multi-page printed material 600 attempts to retreat, it can effectively block the reverse rotation of the stop block 520.

[0032] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 The pressure compensation component 320 includes a second driving member 321, a position sensor 322 and a triggering piece 323. In a specific implementation, the position sensor 322 is installed at an appropriate position of the base 311 to detect the position change of the triggering piece 323. The triggering piece 323 is fixedly connected to the mounting seat 312 and moves with the movement of the mounting seat 312. When the mounting seat 312 moves due to the change in thickness of the multi-page printed material 600, the triggering piece 323 triggers the position sensor 322 and sends a signal to the control system. After receiving the signal, the control system will start the second driving member 321 to drive the base 311 to move toward the mounting seat 312, thereby maintaining the compression amount of the spring 314 and ensuring that the pressure plate 313 applies a constant pressure to the multi-page printed material 600. Through the position sensor 322 and the triggering piece 323, combined with the automatic adjustment function of the second driving member 321, the pressure compensation component 310 senses the change in the thickness of the multi-page printed material 600 and automatically adjusts the pressure, ensuring that no matter how the thickness of the multi-page printed material 600 changes, a constant pressing force can be maintained. This not only improves the adaptability and stability of the storage mechanism, but also reduces the inconvenience and errors caused by manual adjustment.

[0033] In some embodiments, the position sensor 322 uses a photoelectric sensor to detect the position of the trigger piece 323. The photoelectric sensor is composed of a transmitter and a receiver, which are respectively mounted on both sides or relative positions of the base 311. The trigger piece 323 is a component that can block light and is fixedly connected to the mounting seat 312. When the mounting seat 312 moves due to the change in the thickness of the multi-page printed material 600, the trigger piece 323 will move accordingly. When the trigger piece 323 moves to the detection area of ​​the photoelectric sensor, it will block the light emitted by the transmitter, causing the light signal received by the receiver to weaken or disappear. After the photoelectric sensor detects this change, it will output an electrical signal to the control system. After receiving the signal from the photoelectric sensor, the control system will determine the position change of the mounting seat 312 and start the second driving member 321 to drive the base 311 to move toward the mounting seat 312. By adjusting the position of the base 311, the compression amount of the spring 314 can be maintained constant, ensuring that the pressure plate 313 applies a stable pressure to the multi-page printed material 600.

[0034] In other embodiments, the position sensor 322 adopts a contact sensor, such as a micro switch or a travel switch. The contact sensor usually has a movable contact and a fixed contact. When the movable contact contacts the fixed contact, the sensor outputs an electrical signal. The contact sensor is mounted on the base 311, and the trigger sheet 323 is fixedly connected to the mounting seat 312. When the mounting seat 312 moves due to the change in the thickness of the multi-page printed material 600, the trigger sheet 323 touches the movable contact of the contact sensor. Once the trigger sheet 323 contacts the contact, the contact sensor outputs an electrical signal to the control system. After receiving the signal from the contact sensor, the control system will also start the second driving member 321 to drive the base 311 to move to maintain the constant compression of the spring 314.

[0035] Reference Figure 1 Specifically, the second driving member 321 uses a combination of a second motor 3211, a second driving wheel 3212 and a second driven wheel 3213 to drive the pressing assembly through a belt 3214. The second motor 3211 serves as a power source to drive the second driving wheel 3212 to rotate, and the second driving wheel 3212 drives the second driven wheel 3213 to rotate through the belt 3214, thereby realizing the movement of the pressing assembly in the receiving groove 210. The belt 3214 transmission method driven by the second motor 3211 is not only compact in structure and stable in transmission, but also can accurately control the position and speed of the pressing assembly, thereby improving the automation and stability of the storage mechanism.

[0036] Furthermore, in order to prevent the second driving member 321 from occupying the space of the accommodating groove 210 , the second driving member 321 is located below the accommodating groove 210 , and a clearance groove 211 is provided on the bottom wall of the accommodating groove 210 for the base 311 to pass through and connect with the belt 3214 .

[0037] Reference Figure 3 and Figure 4 It should be noted that the base 311 and the mounting seat 312 are connected by a limit pin 315 and a spring 314. The limit pin 315 passes through the first limit hole 3111 of the base 311 and is inserted into the second limit hole 3121 of the mounting seat 312, and the spring 314 is installed at the same time. The two ends of the spring 314 abut against the side walls of the base 311 and the mounting seat 312, respectively, to provide elastic force for the pressing assembly 310. Specifically, the base 311 and the mounting seat 312 are connected by two limit pins 315 and the spring 314, which increases the stability and reliability of the connection. Each limit pin 315 passes through the two first limit holes 3111 of the base 311 and is inserted into the two second limit holes 3121 of the mounting seat 312, and the spring 314 is installed at the same time. In some embodiments, three or more limit pins 315 and springs 314 can be provided to achieve the pressing function of multi-page printed materials 600 with different pressure requirements and different sizes.

[0038] Reference Figure 4 It should be noted that the mounting seat 312 is provided with a vertical plug plate, and the plug plate is provided with a first fixing hole. A slot is provided on the side of the pressure plate 313 facing the mounting seat 312, and the plug plate is inserted into the slot. The side wall of the pressure plate 313 is provided with a second fixing hole, and the first fixing hole and the second fixing hole are fixedly connected to the pressure plate 313 and the mounting seat 312 by fasteners. The structural strength and stability of the pressing assembly 310 are further improved, so that the pressing assembly 310 can still maintain a stable working state when subjected to greater pressure, thereby extending the service life of the storage mechanism. And through the combination of the slot and the plug plate, the installation steps of the pressing plate 313 are simplified, and disassembly, assembly, maintenance and replacement are further facilitated to meet the use requirements. It should be noted that the fasteners can be selected from screws or bolts.

[0039] The present invention also proposes an automated printing device having the above-mentioned conveying mechanism. It is understandable that one or more conveying mechanisms can be provided and arranged and combined according to actual needs. When multiple conveying mechanisms are provided, they are usually arranged adjacent to each other and convey a single multi-page printed material 600 alternately. This layout allows multiple multi-page printed materials 600 to be conveyed alternately on different conveying mechanisms at the same time, realizes the parallelization of the processing of the multi-page printed materials 600, and significantly improves the overall production capacity and efficiency of the automated printing device. On the other hand, by optimizing the layout and workflow of the conveying mechanism, the equipment footprint and manpower input costs are reduced, and the overall economic benefits are improved.

[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
