Description

Technical Field

[0001] This invention relates to the technical field of newspaper production, specifically to a conveying device for stacked newspapers. Background Technology

[0002] As is commonly known, a newspaper is a paper publication that carries news and news commentary, usually printed in loose pages, without binding or a cover.

[0003] The newspaper production process involves the following steps:

[0004] 1. Planning and Content Creation: The editorial team determines the day's news topics and important events, reporters conduct interviews, collect information, write reports, and photographers take relevant photos;

[0005] Second, editing and proofreading: Editors edit the collected manuscripts to ensure the accuracy and readability of the content, and proofread the edited manuscripts to check for spelling, grammar and factual errors;

[0006] Third, typesetting and design: Use computer typesetting software to type out articles, pictures and advertisements, design the page layout, and after the page design is completed, it needs to be reviewed by editors and relevant personnel to ensure that there are no errors;

[0007] Fourth, printing: making the offset plates or other types of plates needed for printing, and printing the typed newspaper through a printing press, usually roller printing, which is fast and efficient;

[0008] 5. Cutting and Packaging: After printing, the newspapers need to be cut to determine the size of each newspaper. The cut newspapers are then neatly packaged and ready for delivery and distribution.

[0009] In the newspaper production process, after the newspaper is cut, a paper folding machine is used to fold the paper into the required number of pages. Before packaging, a stacking machine is used to neatly stack a certain number of newspapers. Then, the neatly stacked newspapers are transported to the packaging mechanism by a belt conveyor for packaging.

[0010] The shortcoming of the existing technology is that, during the process of the newspapers being neatly stacked by the stacking machine being transported to the packing mechanism by the belt conveyor, the stacked newspapers are not compressed. Since the stack of a certain number of newspapers has a certain height, during the conveying process, due to the vibration generated by the equipment or the change in the newspaper conveying speed, there is a risk that the stacked newspapers may collapse due to shaking, which will have an adverse effect on the subsequent packing operation. Summary of the Invention

[0011] The purpose of this invention is to provide a device for conveying stacked newspapers, thereby solving the technical problems in related technologies.

[0012] To achieve the above objectives, the present invention provides the following technical solution:

[0013] A newspaper conveying device after stacking includes a frame and a belt conveyor mechanism mounted on the frame. The belt conveyor mechanism is used to convey the newspapers stacked in the stacker to a baler for baling. The belt conveyor mechanism is provided with a number of hoppers, which are arranged sequentially on the belt conveyor mechanism along its movement trajectory.

[0014] As described above, the hopper includes a support frame connected to a belt conveyor mechanism and a support plate slidably arranged on the support frame. The sliding direction of the support plate on the support frame is consistent with the newspaper stacking direction, and the support frame and the support plate are connected by a scissor mechanism. The frame is equipped with a transmission mechanism, which is used to transmit the power of the hopper corresponding to the stacker position to the hopper corresponding to the baler position. As the amount of newspaper stacked gradually increases, the support plate of the hopper corresponding to the stacker position gradually moves away from the support frame. Based on the transmission action of the transmission mechanism, the support plate of the hopper corresponding to the baler position pushes the stacked newspapers into the baler.

[0015] As described above, each side of the support frame is provided with a roller body, and a spring mechanism is provided at the connection between the roller body and the support frame. Each roller body is connected to the support plate with a shielding cloth. Based on the power of the spring mechanism, the shielding cloth tends to be wound around the roller body.

[0016] As described above, the support frame is oscillatingly connected to the belt of the belt conveyor mechanism, and the axial direction of the oscillation shaft is parallel to the width direction of the belt. A first elastic element is provided between the support frame and the belt. Based on the elastic force of the first elastic element, the support frame tends to keep its surface parallel to the surface of the belt.

[0017] The aforementioned transmission mechanism includes two support plates slidably arranged on the frame. One support plate corresponds to the hopper at the corresponding position of the stacker, and the other support plate corresponds to the hopper at the corresponding position of the packer. The two support plates are connected by a lever assembly.

[0018] The lever assembly described above includes a rotating shaft mounted on the frame and a rod mounted on the rotating shaft. Two support rods are slidably mounted at both ends of the rod, and the two support rods are slidably connected to two support plates in a one-to-one correspondence.

[0019] As mentioned above, the frame is provided with an adjustment mechanism for adjusting the position of the rotating shaft on the rod.

[0020] The aforementioned adjustment mechanism includes two adjustment slots on the frame, each with an adjustment slider that slides in it. The two adjustment sliders are screwed to the two ends of the rotating shaft. After adjusting the position of the rotating shaft on the rod, rotating the shaft locks the two adjustment sliders on the frame.

[0021] As described above, an adjusting block is slidably sleeved on the rod body, and a locking rod is slidably mounted on the adjusting block. In the sliding direction, a second elastic element is provided between the locking rod and the adjusting block. Based on the elastic force of the second elastic element, the locking rod tends to move away from the rod body. The rotating shaft consists of two sections that are screwed together. After adjusting the position of the rotating shaft on the rod body, rotating the shaft locks the two adjusting sliders in the stroke on the frame. The two sections of the rotating shaft approach each other and press the locking rod against the rod body.

[0022] As mentioned above, the support frame is equipped with a locking mechanism. When there are no newspapers piled on the support plate, the locking mechanism locks the support plate to the support frame. When there are newspapers piled on the support plate, the locking mechanism releases the lock on the support plate based on the gravity of the newspapers.

[0023] The beneficial effects of this invention are as follows: by arranging several hoppers on the belt conveyor mechanism, and using the holding space on the hoppers to place the stacked newspapers, the hoppers can effectively restrict the stacked newspapers around them during the process of conveying the stacked newspapers from the stacker to the packing machine, so as to prevent the risk of the stacked newspapers collapsing due to shaking, thereby ensuring the smooth progress of subsequent packing operations.

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 9 The present invention will now be described in further detail.

[0037] This invention provides a newspaper conveying device after stacking, including a frame 1 and a belt conveyor 2 mounted on the frame 1. The belt conveyor 2 is used to convey the newspapers stacked in the stacker to a packing machine for packing operations. The belt conveyor 2 is provided with a plurality of hoppers 3, which are arranged sequentially on the belt conveyor 2 along the movement trajectory of the belt conveyor 2.

[0038] Specifically, for ease of description and understanding, the direction in which the belt conveyor 2 transports the stacked newspapers from the stacker to the baler is designated as the first direction, and the direction in which the newspapers are stacked at the stacker is designated as the second direction. The first and second directions are perpendicular to each other. The stacker and baler are existing technologies and will not be elaborated upon further in this text. The belt conveyor 2 is also existing technology; when referring to certain components, their names will be used directly. In existing technology, during the process of conveying the neatly stacked newspapers from the stacker to the baling mechanism via the belt conveyor 2, the stacked newspapers are not compressed. Due to the considerable height of the stacked newspapers, vibrations generated by the equipment or changes in the newspaper conveying speed during transport can easily cause the stacked newspapers to collapse due to shaking, adversely affecting subsequent baling operations.

[0039] Based on the above problems, this embodiment improves the belt conveyor mechanism 2 by arranging multiple hoppers 3 along its own movement trajectory on the belt of the belt conveyor mechanism 2. In the second direction, the upper bottom surface of the hopper 3 is open, and the other sides and the lower bottom surface are provided with structures to block the movement of newspapers. That is, the hopper 3 forms a sunken structure on the belt, and its size matches the size of the stacked newspapers. For example, if the size of the newspaper is 30cm x 40cm, then the size of the hopper 3 can be 31cm x 41cm. In this way, the newspapers can smoothly enter and exit the hopper 3, and the wear on the edges can be ignored. Therefore, in this embodiment, the belt conveyor mechanism 2 is changed from the traditional two belt rollers to four, and the whole is in the shape of an inverted isosceles trapezoid. This provides movement space for the sunken hopper 3. That is, the hopper 3 corresponding to the stacker can act as a platform for stacking newspapers originally used by the stacker. After a specified number of newspapers are stacked in the hopper 3, the belt conveyor mechanism 2 transports the hopper 3 to the location of the packing machine, and then the stacked newspapers are taken out from the hopper 3 for packing.

[0040] The beneficial effect of this embodiment is that by arranging several hoppers 3 on the belt conveyor mechanism 2, and the holding space on the hoppers 3 is used to place the stacked newspapers, the structural features of the hoppers 3 can effectively restrict the stacked newspapers around them during the process of conveying the stacked newspapers from the stacker to the packing machine, so as to prevent the risk of the stacked newspapers collapsing due to shaking, thereby making the subsequent packing operation proceed smoothly.

[0041] Furthermore, the hopper 3 includes a support frame connected to the belt conveyor mechanism 2 and a support plate 31 slidably arranged on the support frame 30. The sliding direction of the support plate 31 on the support frame 30 is consistent with the newspaper stacking direction, and the support frame 30 and the support plate 31 are connected by a scissor mechanism 32. The frame 1 is provided with a transmission mechanism, which is used to transmit the power of the hopper 3 corresponding to the stacker position to the hopper 3 corresponding to the baler position. As the amount of newspaper stacked gradually increases, the support plate 31 of the hopper 3 corresponding to the stacker position gradually moves away from the support frame 30. Based on the transmission action of the transmission mechanism, the support plate 31 of the hopper 3 corresponding to the baler position pushes the stacked newspapers into the baler.

[0042] Specifically, the support plate 31 is slidably arranged on the support frame 30 along the second direction. When there is no relative sliding between the support plate 31 and the support frame 30 and they are in full contact, the part of the support plate 31 inside the support frame 30 protrudes out of the support frame 30 in the opposite direction along the second direction. That is, when newspapers are piled on the support plate 31, if the newspapers are not placed properly, the edges of the newspapers will contact the support frame 30 at the same time as the support plate 31. The support frame 30 will then hinder the stacking of the newspapers. In other words, as the support plate 31 moves away from the support frame 30 along the second direction, the newspapers will move with the support plate 31 due to gravity. However, due to the obstruction of the support frame 30, the newspapers will deform. Therefore, when the first newspaper is piled on the support plate 31, it can be seen whether the newspaper stacking will be hindered by the support frame 30. If there is an obstruction, the stacking position can be adjusted in time to ensure that subsequent stacking operations can proceed smoothly.

[0043] The scissor mechanism 32 is existing technology and will not be described in detail here. However, during its opening or closing process, a certain damping effect is required so that when there is no newspaper accumulation on the hopper 3, the support plate 31 and the support frame 30 can basically ensure complete contact. As the amount of newspaper accumulation gradually increases, the scissor mechanism 32 can also open more slowly to ensure that the distance that each layer of newspaper moves during accumulation does not change much.

[0044] In the aforementioned embodiment, after the stacked newspapers arrive at the baling machine, they need to be removed from the hopper 3 for baling, which requires external force. Moreover, the hopper 3 is always in a sunken state, which is not conducive to the intermittent circumferential operation of the belt conveyor 2. That is, after the previous stacked newspapers arrive at the baling machine, the hopper 3 at the stacking machine performs the newspaper stacking operation. Therefore, in this embodiment, a transmission mechanism is provided on the frame 1. That is, in the initial state, the hoppers 3 are all in a closed state. At this time, the support plate 31 protrudes from the support frame 30 in the opposite direction of the second direction. When the hopper 3 in the initial state arrives at the corresponding position of the stacking machine, there will be a hopper 3 at the corresponding position of the baling machine. Therefore, the function of the transmission mechanism is that as the stacking machine gradually stacks the newspapers onto the hopper 3 at its corresponding position, as the support plate 31 gradually moves along the second direction, the transmission mechanism will transmit the power of the support plate 31 to the support plate 31 at the corresponding position of the baling machine, so that the support plate 31 moves in the opposite direction of the second direction and sends out the stacked newspapers in the hopper 3 for subsequent baling operations.

[0045] In a preferred embodiment, each side of the support frame 30 is provided with a roller body 33, and a spring mechanism is provided at the connection between the roller body 33 and the support frame 30. Each roller body 33 is connected to the support plate 31 with a shielding cloth 34. Based on the power of the spring mechanism, the shielding cloth 34 tends to be wound around the roller body 33.

[0046] Specifically, since the support frame 30 and the support plate 31 are connected by a scissor mechanism 32, and the arrangement of the scissor mechanism 32 can be used to restrict the stacked newspapers around their edges, the structural features of the scissor mechanism 32 can easily cause damage to the edges of the newspapers. Therefore, in this embodiment, rollers 33 are arranged on each plate of the support frame 30, and each roller 33 is connected to the support plate 31 with a shielding cloth 34. In this way, the shielding cloth 34 separates the newspapers from the scissor mechanism 32 to avoid damage to the edges of the newspapers. A spring mechanism is also arranged at the connection between the body 33 and the support frame 30. As the support plate 31 moves away from the support frame 30, the shielding cloth 34 is stretched. At this time, the spring mechanism is also wound up, that is, the elasticity of the spring mechanism increases. In this way, the elasticity of the spring mechanism can be used to restrict the separation of the support plate 31 and the support frame 30 again based on the damping effect of the scissor mechanism 32 after the shielding cloth 34 is rolled up. Thus, when the hopper 3 is not in use, it can follow the belt conveyor mechanism 2 to perform circumferential reciprocating motion without being obstructed.

[0047] In an optional embodiment, the support frame 30 is oscillatingly connected to the belt conveyor 2, and the axial direction of the oscillating shaft 35 is parallel to the width direction of the belt. A first elastic element is provided between the support frame 30 and the belt. Based on the elastic force of the first elastic element, the support frame 30 tends to keep its surface parallel to the belt surface. That is, when the belt passes through each belt roller, the hopper 3 arranged on it needs to change its direction at that point. Therefore, the support frame 30 is oscillatingly arranged on the belt using the oscillating shaft 35, and the elastic force of the first elastic element provides a force to keep the support frame 30 parallel to the belt surface. When the support frame 30 passes through the belt roller, the support frame 30 will first flip on the belt. Based on the elastic force of the first elastic element, the support frame 30 can be parallel to the belt surface again.

[0048] Preferably, the transmission mechanism includes two support plates 36 slidably arranged on the frame 1. One support plate 36 corresponds to the hopper 3 at the corresponding position of the stacker, and the other support plate 36 corresponds to the hopper 3 at the corresponding position of the packer. The two support plates 36 are connected by a lever assembly.

[0049] Specifically, along the width direction of the belt, the frame 1 has two sets of guide grooves 37, each set having two guide grooves 37, which are symmetrically arranged in the first direction. Each support plate 36 has two guide blocks 38 fixedly connected to it, and the two guide blocks 38 are slidably connected to the corresponding two guide grooves 37. Thus, the support plate 36 at the stacking machine can be moved together with the support plate 31 at the corresponding position as it moves in the second direction. The support plate at the baling machine is pushed by the lever assembly to move the corresponding support plate 31 in the opposite direction in the second direction. In an optional embodiment, the lever assembly includes a rotating shaft 40 on the frame 1 and a lever assembly on the rotating shaft 40. The rod 39 has two slidably mounted support rods at both ends of its axial direction. The two support rods are slidably connected to two support plates 36 in a one-to-one correspondence. That is, as the amount of newspapers piled up on the hopper 3 at the accumulation point gradually increases, the support plate 31 moves along the second direction based on the gravity of the newspapers. The support plate 31 will then push the corresponding support plate to move together. One end of the lever assembly is squeezed and swung along the second direction, and the other end will push the support plate at the corresponding position of the baler to move in the opposite direction along the second direction. The support plate 31 corresponding to the moving pusher of the support plate moves in the opposite direction along the second direction, pushing the piled newspapers out of the hopper 3 so that subsequent baling operations can be carried out.

[0050] Furthermore, the frame 1 is provided with an adjustment mechanism for adjusting the position of the rotating shaft 40 on the rod 39; the adjustment mechanism includes two adjustment slots 41 opened on the frame 1, and an adjustment slider 42 is slidably provided in each adjustment slot 41. The two adjustment sliders 42 are screwed to the two ends of the rotating shaft 40 respectively. After adjusting the position of the rotating shaft 40 on the rod 39, the rotating shaft locks the two adjustment sliders 42 on the frame 1.

[0051] Specifically, depending on the amount of newspapers piled up each time, as the amount of newspapers piled up in the hopper 3 at the stacker increases, the newspapers piled up in the hopper 3 at the baler can slowly move in the opposite direction at a basically uniform speed. Therefore, the position of the rotating shaft 40 on the rod 39 needs to be adjusted according to actual needs. In this embodiment, an adjustment mechanism for adjusting the position of the rotating shaft 40 on the rod 39 is provided on the frame 1. That is, the adjustment groove 41 is elongated. When there are no newspapers piled up in the hopper 3 at the stacker, the length direction of the rod 39 is parallel to the length direction of the adjustment groove 41. Okay, when it is necessary to adjust the position of the rotating shaft 40 on the rod 39, push the adjusting slider 42 to slide in the adjusting groove 41 to the desired position, and then rotate the rotating shaft 40. By using the screw connection, the positions of the two adjusting sliders 42 are locked. That is, the rotation of the rotating shaft 40 makes the two adjusting sliders 42 tend to move away from the adjusting groove 41 and move closer to each other along the axial direction of the rotating shaft 40. However, the adjusting sliders 42 can only slide along the length direction of the adjusting groove 41. In this way, the normal pressure between the adjusting sliders 42 and the side wall of the adjusting groove 41 (axially upward of the rotating shaft 40) increases, thereby achieving the sliding restriction of the adjusting sliders 42.

[0052] Furthermore, an adjusting block 43 is slidably sleeved on the rod 39, and a locking rod 44 is slidably mounted on the adjusting block 43. In the sliding direction, a second elastic element is provided between the locking rod 44 and the adjusting block 43. Based on the elastic force of the second elastic element, the locking rod 44 tends to move away from the rod 39. The rotating shaft 40 consists of two sections screwed together. After adjusting the position of the rotating shaft 40 on the rod 39, rotating the shaft locks the two adjusting sliders 42 in the stroke on the frame 1. The two sections of the rotating shaft 40 approach each other and press the locking rod 44 against the rod 39.

[0053] Specifically, after the position of the rotating shaft 40 on the rod 39 is adjusted, it also needs to be restricted to prevent the position of the rotating shaft 40 from changing during the swing of the rod 39, making it difficult for the position changes of the hopper 3 at the stacker and the hopper 3 at the packer to be smooth. Therefore, in this embodiment, an adjusting block 43 is set at the connection between the rod 39 and the rotating shaft 40. The adjusting block 43 is slidably sleeved on the rod 39, and a locking rod 44 is slidably set on the adjusting block 43. The rotating shaft 40 is set to consist of two segments that are inserted into each other. That is, during the rotation, the two segments of the rotating shaft 40 will approach each other. In this way, the connection between the rotating shaft 40 and the adjusting slider 42 can be modified to a rotatable connection. Similarly, during the process of the two segments of the rotating shaft 40 approaching each other, the position of the adjusting slider 42 is locked. The approach of the two segments of the rotating shaft 40 will generate a squeezing effect with one end of the locking rod 44 based on a wedge fit, so that the other end of the locking rod 44 abuts against the rod 39, thereby fixing the position of the rotating shaft 40 on the rod 39.

[0054] Preferably, the support frame 30 is provided with a locking mechanism 5. When there are no newspapers piled on the support plate 31, the locking mechanism 5 locks the support plate 31 on the support frame 30. When there are newspapers piled on the support plate 31, the locking mechanism 5 releases the lock on the support plate 31 based on the gravity of the newspapers.

[0055] Specifically, in the aforementioned embodiments, in the initial state, the damping effect of the scissor mechanism 32 and the elastic force of the spring mechanism allow the support plate 31 and the corresponding support frame to be in near-complete contact. However, during use, as the number of uses and duration increase, the elastic force provided by the spring mechanism and the damping force provided by the scissor mechanism 32 may become insufficient to ensure that the support plate 31 and the corresponding support frame 30 are in near-complete contact. Therefore, in this embodiment, a locking mechanism 5 is arranged on the support frame 30. When there are no newspapers piled on the support plate 31, the locking mechanism 5 locks the support plate 31 onto the support frame 30. When there are newspapers piled on the support plate 31, the locking mechanism 5 releases the lock on the support plate 31 based on the gravity of the newspapers.

[0056] The locking mechanism 5 includes a compression rod 50 slidably arranged at each corner of the support plate 31. Two first locking blocks 51 are slidably provided at each corner of the support plate 31, and a third elastic element is provided between each first locking block 51 and the support plate 31 in the sliding direction. Each scissor mechanism 32 has a locking slot 52 that engages with the corresponding first locking block 51. The support plate 31 is divided into an upper layer 310 and a lower layer 311. The upper layer 310 is slidably arranged on the lower layer 311 along a second direction and is provided with a fourth elastic element. As the amount of newspaper accumulated on the upper layer 310 gradually increases, the upper layer 310 first compresses the fourth elastic element. During this process, the upper layer... Layer 310 and each pressing rod 50 form a pressing action based on a wedge fit, so that each pressing rod 50 presses the two first locking blocks 51 at the corresponding position, causing the first locking blocks 51 to disengage from the locking holes 52 they are inserted into, thereby releasing the locking of the support plate 31 on the support frame 30. There is also a wedge fit between the scissor mechanism 32 and the corresponding first locking block 51. That is, as the support plate 31 gradually comes into contact with the support frame 30, the scissor mechanism 32 will first press the first locking block 51. When the first locking block 51 corresponds to the locking hole 52, the two are inserted based on the rebound force of the third elastic element, thereby locking and restricting the scissor mechanism 32.

[0057] Furthermore, at each corner of the lower layer 311 of the support plate 31, a second locking block 53 is fixedly connected to the first locking block 51. That is, during the process of the extrusion rod 50 pressing the two first locking blocks 51 at the corresponding positions, the two first locking blocks 51 will drive their respective fixed second locking blocks 53 into the guide groove 37. Thus, during the process of stacking newspapers on the support plate 31, the second locking blocks 53 will slide along the guide groove 37. Based on the sliding cooperation between the second locking blocks 53 and the guide groove 37, even if the belt drive mechanism vibrates during the stacking process, it will not affect the neatness of the newspaper stacking. The stacker itself has a certain elastic deformation, which becomes more pronounced as the weight of the stacked newspapers increases. This can lead to misalignment between the hopper 3 and the stacker, thus affecting the stacking of the newspapers. In this embodiment, the problem can be solved by the cooperation of the second locking block 53 and the guide groove 37. The guide groove 37 at the corresponding position of the stacker and the guide groove 37 at the corresponding position of the packing machine are connected by a connecting groove 54. That is, the support plate 31 follows the second locking block 53 from the guide groove 37 at the corresponding position of the stacker through the connecting groove 54 to the guide groove 37 at the corresponding position of the packing machine, and is then pushed in the opposite direction.

[0058] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
