Description

Technical Field

[0001] The invention relates to the technical field related to newspaper production, in particular to a device for conveying piled newspapers. Background Art

[0002] As is known to all, a newspaper refers to a paper publication that publishes news and news comments, is usually printed in loose pages, is not bound, and has no cover.

[0003] The newspaper production process goes through the following steps:

[0004] 1. Planning and content creation: The editorial team determines the news topics and important events of the day, conducts interviews, collects information, writes reports, and photographers take relevant photos;

[0005] 2. Editing and proofreading: The editor will 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] 3. Typesetting and design: Use computer typesetting software to typeset articles, pictures and advertisements, and design the layout. After the layout design is completed, it must be reviewed by editors and relevant personnel to ensure that it is correct;

[0007] Fourth, printing: make the offset plate or other types of plates required for printing, and print the typeset 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 neatly packaged and ready for distribution and issuance.

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

[0010] The shortcoming of the prior art is that, during the process of newspapers neatly stacked by the stacker being transported to the packaging mechanism via the belt conveyor mechanism, some of the stacked newspapers are not pressed down. Since a certain number of newspapers are stacked at a certain height, during the transportation process, due to the vibration generated by the equipment or the change in the newspaper transportation speed, there is a risk that the stacked newspapers may collapse due to shaking, which has an adverse effect on the subsequent packaging operation.

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Fig. 9 The present invention is further described in detail.

[0037] An embodiment of the present invention provides a device for conveying stacked newspapers, comprising a frame 1 and a belt conveyor mechanism 2 arranged on the frame 1, wherein the belt conveyor mechanism 2 is used to convey newspapers stacked in a stacker to a baler for baling, and the belt conveyor mechanism 2 is provided with a plurality of hoppers 3, and along the movement trajectory of the belt conveyor mechanism 2, the plurality of hoppers 3 are arranged in sequence on the belt conveyor mechanism 2.

[0038] Specifically, for ease of description and understanding, the direction in which the belt conveyor mechanism 2 conveys the stacked newspapers from the stacker to the baler is a first direction, and the direction in which the newspapers are stacked at the stacker is a second direction, and the first direction and the second direction are perpendicular to each other, wherein the stacker and the baler are both prior art and will not be described in detail in this article, and the belt conveyor mechanism 2 is also prior art, and the names of these components are directly used when referring to some of the components. In the prior art, when the newspapers neatly stacked by the stacker are transported to the baler via the belt conveyor mechanism 2, the stacked newspapers are not pressed down, and since a certain number of newspapers are stacked to a certain height, during the transportation process, due to the vibration generated by the equipment or the change in the newspaper transportation speed, there is a risk that the stacked newspapers will collapse due to shaking, which will have an adverse effect on the subsequent baling operation.

[0039] Based on the above problems, in this embodiment, the belt conveyor mechanism 2 is improved, that is, a plurality of hoppers 3 are arranged on the belt of the belt conveyor mechanism 2 along its own motion trajectory. In the second direction, the upper bottom surface of the hopper 3 is open, and the other side surfaces and the lower bottom surface are provided with a structure to block the movement of newspapers, that is, the hopper 3 forms a sinking structure on the belt, and its size matches the size of the stacked newspapers. For example, if the size of the newspaper is 30cmx40cm, then the size of the hopper 3 can be 31cmx41 cm, so that the newspaper can smoothly enter and exit the hopper 3, and the wear on the edge can also be ignored. Therefore, in this embodiment, the belt conveyor mechanism 2 is also set to four from the traditional two belt rollers, and the overall structure is an inverted isosceles trapezoidal structure, so that a movement space can be provided for the hopper 3 of the sinking structure, that is, the hopper 3 at the corresponding position of the stacker can serve as a platform for stacking newspapers originally used by the stacker. After the hopper 3 stacks a specified number of newspapers at this location, the belt conveyor mechanism 2 transports the hopper 3 to the location of the baler, and then takes the stacked newspapers out of the hopper 3 for packaging.

[0040] The beneficial effect of this embodiment is that by arranging a plurality of hoppers 3 on the belt conveyor mechanism 2, the containing space on the hopper 3 is used to place the stacked newspapers. Then, in the process of conveying the stacked newspapers from the stacker to the baler, the structural characteristics of the hopper 3 can effectively restrict the stacked newspapers around to prevent the risk of the stacked newspapers collapsing due to shaking, thereby allowing the subsequent baling operation to 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 scissors mechanism 32, and a transmission mechanism is provided on the frame 1, and the transmission mechanism is used to transmit the power of the hopper 3 corresponding to the stacking machine position to the hopper 3 corresponding to the baler position; for the hopper 3 at the corresponding position of the stacker, as the amount of newspaper stacking gradually increases, the support plate 31 gradually moves away from the support frame 30; for the hopper 3 at the corresponding position of the baler, based on the transmission action of the transmission mechanism, the support plate 31 pushes the stacked newspapers into the baler.

[0042] Specifically, the supporting plate 31 is arranged to slide on the supporting frame 30 along the second direction, and no relative sliding occurs between the supporting plate 31 and the supporting frame 30. When they are in full contact, the portion of the supporting plate 31 in the supporting frame 30 protrudes out of the supporting frame 30 in the opposite direction along the second direction. That is, when newspapers are piled on the supporting plate 31, if the position of the newspapers is not appropriate, the edge of the newspapers will contact the supporting plate 31 and the supporting frame 30 at the same time, and the supporting frame 30 will hinder the stacking of the newspapers. That is, in the process of the supporting plate 31 moving away from the supporting frame 30 along the second direction, the newspapers will move with the supporting plate 31 due to gravity, and will be deformed due to the obstruction of the supporting frame 30. Therefore, when the first newspaper is piled on the supporting plate 31, it can be seen whether the stacking of the newspapers will be obstructed by the support frame 30. If there is an obstruction, the stacking position can be adjusted in time to ensure that the subsequent stacking operation proceeds smoothly.

[0043] The scissor mechanism 32 is a prior art and will not be described in detail herein. However, a certain damping effect is required during its expansion or closing process, so that when there is no newspaper accumulation on the hopper 3, the support plate 31 and the support frame 30 can basically ensure full contact, and as the amount of newspaper accumulation gradually increases, the scissor mechanism 32 can also be slowly expanded to ensure that the distance moved by each layer of newspapers during accumulation does not change much.

[0044] In the aforementioned embodiment, after the stacked newspapers arrive at the baler, they need to be taken out of the hopper 3 for packaging, which requires the use of external force, and the hopper 3 is always in a sinking state, which is not conducive to the intermittent circumferential operation of the belt conveyor mechanism 2, that is, after the previous stacked newspapers arrive at the baler, the hopper 3 at the stacker 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 hopper 3 is in a closed state, at this time, the supporting plate 31 is protruding from the support frame 30 in the opposite direction of the second direction, when the hopper 3 in the initial state reaches the corresponding position of the stacker, there will be a hopper 3 at the corresponding position of the baler, so the role of the transmission mechanism is that in the process of the stacker gradually stacking the newspapers on the hopper 3 at its corresponding position, as the supporting plate 31 gradually moves along the second direction, the transmission mechanism will transmit the power of the supporting plate 31 to the supporting plate 31 at the corresponding position of the baler, so that the supporting plate 31 moves in the opposite direction along the second direction, and the stacked newspapers in the hopper 3 are sent out for subsequent packaging operations.

[0045] In a preferred embodiment, a roller body 33 is provided on each side of the support frame 30, a clockwork mechanism is provided at the connection between the roller body 33 and the support frame 30, and a shielding cloth 34 is connected between each roller body 33 and the supporting plate 31. Based on the power of the clockwork 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 based on the arrangement of the scissor mechanism 32, it can be used to restrict the stacked newspapers on all sides, but the structural characteristics of the scissor mechanism 32 are easy to cause damage to the edge of the newspaper. Therefore, in this embodiment, a roller body 33 is arranged on each board of the support frame 30, and a shielding cloth 34 is connected between each roller body 33 and the support plate 31. In this way, the shielding cloth 34 is used to separate the newspaper from the scissor mechanism 32 to avoid damage to the edge of the newspaper, and each roller body 33 is connected to the support plate 31. A clockwork mechanism is also arranged at the connection between the body 33 and the support frame 30. When the supporting plate 31 and the support frame 30 are moving away from each other, the shielding cloth 34 is stretched. At this time, the clockwork mechanism is also stretched, that is, the elastic force of the clockwork mechanism increases. In this way, the elastic force of the clockwork mechanism can be utilized. After the shielding cloth 34 is rolled up, based on the damping effect of the scissors-type mechanism 32, the elastic force can be used to limit the separation of the supporting plate 31 and the support frame 30 again. In this way, when the hopper 3 is not in use, it can follow the belt conveyor mechanism 2 to perform circumferential reciprocating motion without being hindered.

[0047] In an optional embodiment, the support frame 30 is swingably connected to the belt of the belt conveyor mechanism 2, and the axial direction of the swing shaft 35 is parallel to the width direction of the belt. A first elastic member is provided between the support frame 30 and the belt. Based on the elastic force of the first elastic member, 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 thereon needs to change its direction at that location. Therefore, the support frame 30 is swingably arranged on the belt using the swing shaft 35, and then the elastic force of the first elastic member is used to provide 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 over on the belt, and based on the elastic force of the first elastic member, 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 baler, and the two support plates 36 are connected by a lever assembly.

[0049] Specifically, along the width direction of the belt, two groups of guide grooves 37 are provided on the frame 1, each group of guide grooves 37 has two guide blocks 38, and are symmetrically arranged in the first direction. Two guide blocks 38 are fixedly connected to each support plate 36, and the two guide blocks 38 are slidably connected to the corresponding two guide grooves 37, so that the support plate 36 at the stacker can be driven to move together when the supporting plate 31 at the corresponding position moves along the second direction. The support plate at the baler is acted upon by the lever assembly, and can push the corresponding supporting plate 31 to move in the opposite direction along the second direction. In an optional embodiment, the lever assembly includes a rotating shaft 40 provided on the frame 1 and a rotating shaft 40 provided on the rotating shaft 40 The rod body 39 on the rod body 39 has two support rods slidably provided at both axial ends of the rod body 39, and the two support rods are slidably connected with the two support plates 36 in a one-to-one correspondence, that is, as the amount of newspapers piled on the hopper 3 at the stacking location gradually increases, the supporting plate 31 moves in the second direction based on the gravity of the newspapers, and the supporting plate 31 will push the corresponding supporting plate to move together, then one end of the lever assembly is squeezed and swung in the second direction, and the other end will push the supporting plate at the corresponding position of the baler to move in the opposite direction along the second direction, and the supporting plate 31 corresponding to the moving pusher of the supporting plate moves in the opposite direction along the second direction, pushing the stacked newspapers out of the hopper 3 for subsequent packaging operations.

[0050] Furthermore, the frame 1 is provided with an adjustment mechanism for adjusting the position of the rotating shaft 40 on the rod body 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 correspondingly screwed to the two ends of the rotating shaft 40. After adjusting the position of the rotating shaft 40 on the rod body 39, the shaft rod is rotated to lock the two adjustment sliders 42 on the frame 1.

[0051] Specifically, according to the amount of newspapers piled up each time, the amount of newspapers piled up on the hopper 3 at the stacking machine position is increasing, and the newspapers piled up in the hopper 3 at the baler can be slowly moved in the second reverse direction at a substantially uniform speed. In this way, the position of the rotating shaft 40 on the rod body 39 needs to be adjusted according to actual needs. In this embodiment, an adjusting mechanism for adjusting the position of the rotating shaft 40 on the rod body 39 is provided on the frame 1, that is, the adjusting slot 41 is in the shape of a long strip. When the hopper 3 at the stacking machine is not piled up with newspapers, the length direction of the rod body 39 is parallel to the length direction of the adjusting slot 41. When it is necessary to adjust the position of the rotating shaft 40 on the rod body 39, the adjusting slider 42 is pushed to slide in the adjusting groove 41 to the desired position, and then the rotating shaft 40 is rotated. The positions of the two adjusting sliders 42 are locked by means of threaded connection, that is, the rotation of the rotating shaft 40 causes the two adjusting sliders 42 to have a tendency to separate from the adjusting groove 41 and approach each other along the axial direction of the rotating shaft 40, but the adjusting slider 42 can only slide along the length direction of the adjusting groove 41, so that the positive pressure between the adjusting slider 42 and the side wall of the adjusting groove 41 (in the axial direction of the rotating shaft 40) increases, thereby realizing the sliding restriction of the adjusting slider 42.

[0052] Furthermore, an adjustment block 43 is slidably sleeved on the rod body 39, and a locking rod 44 is slidably provided on the adjustment block 43, and in the sliding direction, a second elastic member is provided between the locking rod 44 and the adjustment block 43. Based on the elastic force of the second elastic member, the locking rod 44 tends to move away from the rod body 39; the rotating shaft 40 is composed of two sections that are screwed together. After adjusting the position of the rotating shaft 40 on the rod body 39, the shaft is rotated to lock the two adjusting sliders 42 in the stroke on the frame 1, and the two sections of the rotating shaft 40 approach each other to squeeze the locking rod 44 against the rod body 39.

[0053] Specifically, after the position of the rotating shaft 40 on the rod body 39 is adjusted, it is also necessary to limit it to prevent the position of the rotating shaft 40 from changing during the swinging of the rod body 39, making it difficult to smoothly change the position of the hopper 3 at the stacker and the baler. Therefore, in this embodiment, an adjustment block 43 is provided at the connection between the rod body 39 and the rotating shaft 40. The adjustment block 43 is slidably sleeved on the rod body 39, and a locking rod 44 is slidably provided on the adjustment block 43. The rotating shaft 40 is provided with two sections that are plugged into each other, that is, during the rotation process, the two sections of the rotating shaft 40 will approach each other, so that the rotating shaft 40 and the adjusting slider 42 can be modified to be a rotating connection. Similarly, during the process of the two sections of the rotating shaft 40 approaching each other, the position of the adjusting slider 42 is locked. The mutual approach of the two sections of the rotating shaft 40 will produce an extrusion effect based on the wedge fit between the one end of the locking rod 44, so that the other end of the locking rod 44 abuts against the rod body 39, thereby fixing the position of the rotating shaft 40 on the rod body 39.

[0054] Preferably, a locking mechanism 5 is provided 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 on the support frame 30. When newspapers are 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 embodiment, in the initial state, based on the damping effect of the scissor mechanism 32 and the elastic force of the clockwork mechanism, the support plate 31 and the corresponding support frame can be basically completely in contact with each other. However, during use, as the number of uses and duration increase, the elastic force provided by the clockwork mechanism and the damping force provided by the scissor mechanism 32 may be insufficient to make the support plate 31 and the corresponding support frame 30 basically completely in contact with each other. Therefore, in this embodiment, a locking mechanism 5 is arranged on the support frame 30. When there are no newspapers stacked on the support plate 31, the locking mechanism 5 locks the support plate 31 on the support frame 30. When there are newspapers stacked 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 an extrusion rod 50 slidably arranged at a corresponding position of each corner of the supporting plate 31, two first locking blocks 51 are slidably arranged at each corner of the supporting plate 31, and in the sliding direction, a third elastic member is provided between each first locking block 51 and the supporting plate 31, and each scissor mechanism 32 is provided with a locking port 52 plugged with the first locking block 51 at the corresponding position, wherein the supporting plate 31 is divided into an upper layer 310 and a lower layer 311, and the upper layer 310 is slidably arranged on the lower layer 311 along the second direction, and is provided with a fourth elastic member, when the amount of newspapers piled on the upper layer 310 gradually increases, the upper layer 310 first squeezes the fourth elastic member, and in this process, the upper layer 310 squeezes the fourth elastic member. A squeezing action is formed between the layer 310 and each squeezing rod 50 based on the wedge-shaped fit, so that each squeezing rod 50 then squeezes the two first locking blocks 51 at the corresponding position, so that the first locking block 51 is disengaged from the locking port 52 plugged therein, thereby releasing the lock of the support plate 31 on the support frame 30, wherein a wedge-shaped fit is also present between the scissor-type mechanism 32 and the corresponding first locking block 51, that is, in the process of gradual contact between the support plate 31 and the support frame 30, the scissor-type mechanism 32 will first squeeze the first locking block 51, and when the first locking block 51 corresponds to the locking port 52, based on the rebound force of the third elastic member, the two are plugged in to achieve locking restriction on the scissor-type mechanism 32.

[0057] Furthermore, a second locking block 53 is fixedly connected to the first locking block 51 at each corner of the lower layer 311 of the supporting plate 31, that is, when the squeezing rod 50 squeezes the two first locking blocks 51 at the corresponding positions, the two first locking blocks 51 will drive the second locking blocks 53 fixed to them to enter the guide groove 37, so that when newspapers are stacked on the supporting 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 transmission mechanism vibrates during the newspaper stacking process, it will basically not affect the neatness of the newspaper stacking, and the belt of the belt transmission mechanism will not be affected. The support plate 31 has a certain elastic deformation, which becomes more obvious as the weight of the stacked newspapers increases, which will cause the hopper 3 and the stacker to be out of alignment, and the stacking of newspapers will also be affected. In this embodiment, the problem can be solved by the cooperation of the second locking block 53 and the guide groove 37, wherein the guide groove 37 at the corresponding position of the stacker is connected with the guide groove 37 at the corresponding position of the baler through the 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 baler, and then is pushed in the second direction.

[0058] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that 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 above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the protection of the present invention.
