Description

Technical Field

[0001] This utility model relates to the field of packaging and transportation equipment technology, and in particular to a bidirectional moving device for paper stacks. Background Technology

[0002] On the production and transportation lines of materials such as paper stacks, it is often necessary to transport and transfer the paper stacks. This is usually done by using modules to drive the paper stacks and other materials for transport and transfer.

[0003] However, during the transfer of materials such as paper stacks, centering is required to ensure the accuracy of subsequent processes. In existing technologies, an additional paper stack offset correction device is added to center the paper stacks, thus meeting the centering requirements. However, to meet the combined needs of "conveyance + centering + transfer," existing technologies require the combined use of conveyors, alignment machines, and transfer vehicles, increasing equipment procurement costs, requiring additional space, and causing potential jams between equipment connections, further reducing the efficiency of transfer and paper stack centering. Utility Model Content

[0004] Therefore, in order to overcome at least some of the defects and deficiencies of the prior art, this utility model provides a bidirectional paper stack moving device.

[0005] On one hand, an embodiment of this utility model proposes a bidirectional paper stack moving device, comprising: a support member; a ground rail disposed at the bottom end of the support member; a paper stack conveying mechanism disposed on the support member; a lateral moving mechanism disposed between the support member and the paper stack conveying mechanism and drivingly connected to the paper stack conveying mechanism; a longitudinal moving mechanism disposed on the support member and slidably connected to the ground rail; and a paper stack positioning detection mechanism disposed at both ends of the support member and corresponding to the paper stack conveying mechanism, wherein the paper stack positioning detection mechanism is electrically connected to the lateral moving mechanism and the longitudinal moving mechanism respectively; wherein the paper stack positioning detection mechanism is used to detect the position of the paper stack on the paper stack conveying mechanism and control the lateral moving mechanism to move, so that the paper stack on the paper stack conveying mechanism is displaced to the center position of the central frame.

[0006] In one embodiment of this utility model, the paper stack positioning detection mechanism includes a paper stack detection element and a paper stack distance detection element. The paper stack detection element is disposed on one end of the support member and located near the paper stack input end of the paper stack conveying mechanism. The paper stack distance detection element is disposed on the other end of the support member and faces the conveying surface disposed on the paper stack conveying mechanism. The paper stack distance detection element is electrically connected to the lateral moving mechanism and the paper stack detection element is electrically connected to the longitudinal moving mechanism.

[0007] In one embodiment of the present invention, the device further includes a positioning detection contact, which is disposed on one end of the support member near the paper stack conveying mechanism and is electrically connected to the paper stack distance detection member.

[0008] In one embodiment of the present invention, the lateral movement mechanism includes a chain drive component and a lateral movement drive component. The chain drive component is electrically connected to the lateral movement drive component. The lateral movement drive component is disposed on one end of the support component. The chain drive component is disposed on the side of the support component away from the ground rail and is drively connected to the paper stack conveying mechanism.

[0009] In one embodiment of the present invention, the lateral movement mechanism further includes a guide rail, which is disposed on the side of the support member away from the ground rail and adjacent to the chain drive member.

[0010] In one embodiment of the present invention, the longitudinal moving mechanism includes a longitudinal moving drive and a first sliding member. The longitudinal moving drive is electrically connected to the first sliding member, and the first sliding member corresponds to the ground rail and is slidably connected to the ground rail.

[0011] In one embodiment of the present invention, the ground rails include at least two rails, which are symmetrically distributed on both sides of the bottom of the support member.

[0012] In one embodiment of the present invention, the longitudinal moving mechanism further includes a limiting member and a second sliding member. The limiting member is disposed on the first sliding member, and the first sliding member and the second sliding member are drivenly connected. The first sliding member is located on one of the two ground rails, and the second sliding member is located on the other of the two ground rails.

[0013] In one embodiment of this utility model, a support plate is provided at the end of the support member away from the ground rail, and the support plate is fixedly connected to the paper stack conveying mechanism.

[0014] In one embodiment of the present invention, the bidirectional paper stack moving device further includes a drag chain component, which is disposed on one side of the support component.

[0015] As can be seen from the above, this utility model has the following beneficial effects: This application enables the paper stack conveying mechanism to move laterally and longitudinally by setting up a lateral movement mechanism and a longitudinal movement mechanism. By setting up a paper stack positioning detection mechanism electrically connected to the lateral movement mechanism, the paper stack on the paper stack conveying mechanism is positioned. Then, the paper stack positioning detection mechanism controls the lateral movement mechanism to move the paper stack conveying mechanism laterally, thereby centering the paper stack. This allows the bidirectional paper stack moving device to integrate the functions of "lateral correction + longitudinal transfer + conveying" simultaneously, eliminating the need for multiple devices to be used together, improving transfer efficiency and reducing equipment costs.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-2As shown, this utility model embodiment provides a bidirectional paper stack moving device 1. The bidirectional paper stack moving device 1 includes, for example, a support member 10, a ground rail 20, a paper stack conveying mechanism 30, a lateral moving mechanism 40, a longitudinal moving mechanism 50, and a paper stack positioning detection mechanism 60. Specifically, the ground rail 20 is disposed on the bottom end of the support member 10. The paper stack conveying mechanism 30 is disposed on the support member 10, for example, at the end of the support member away from the ground rail 20. The lateral moving mechanism 40 is disposed between the support member 10 and the paper stack conveying mechanism 30 and is kinetically connected to the paper stack conveying mechanism 30. The longitudinal moving mechanism 50 is disposed on the support member 10 and is slidably connected to the ground rail 20. The paper stack positioning detection mechanism 60 is disposed at both ends of the support member 10 and corresponds to the paper stack conveying mechanism 30, and is electrically connected to the lateral moving mechanism 40 and the longitudinal moving mechanism 50, respectively. The paper stack positioning detection mechanism 60 is used to detect the position of the paper stack on the paper stack conveying mechanism 30 and control the lateral moving mechanism 40 to move so that the paper stack on the paper stack conveying mechanism 30 is located at the center position of the support member 10.

[0022] The support member 10 may be, for example, a support structure for the paper stack conveying mechanism 30, and may be, for example, a support plate, which may be, for example, a hollow rectangular plate. The ground rail 20 may be, for example, a slide rail or a track, which may be, for example, a slide rail with grooves or a slide rail with protrusions. The paper stack conveying mechanism 30 may be, for example, a conveyor belt or a conveyor plate, on which paper stacks are placed. The lateral moving mechanism 40 may be used, for example, to drive the paper stack conveying mechanism 30 along a certain direction. Figure 1 The longitudinal movement mechanism 50 can, for example, be used to drive the entire support member 10 along the X direction as shown. Figure 1 The Y-direction movement shown can also drive the paper stack conveying mechanism 30 to move along the Y-direction. The paper stack positioning detection mechanism 60 may, for example, include two symmetrically arranged distance detectors and a processor. When the paper stack is located on the paper stack conveying mechanism 30, the left distance detector detects the distance from the left distance detector to the leftmost edge of the paper stack, and the right distance detector detects the distance from the right distance detector to the rightmost edge of the paper stack. After obtaining the two distance data, they are transmitted to the processor, which compares the two data and obtains the following result: 1. When the distance data on the left side is large, it is determined that the paper stack is in a state of being biased to the right on the paper stack conveying mechanism. At this time, the lateral movement mechanism 40 is controlled to correct the deviation to the left until the distance data on the left side is equal to the distance data on the right side. 2. When the distance data on the right is large, it is determined that the paper stack is in a state of being too far to the left on the paper stack conveying mechanism. At this time, the lateral movement mechanism 40 is controlled to correct the deviation to the right until the distance data on the left and right are equal. 3. When the distance data on the left side is the same as the distance data on the right side, it is determined that the paper stack is in a centered state on the paper stack conveying mechanism, and no processing is performed at this time.

[0023] This application enables the paper stack conveyor 30 to move laterally and longitudinally by setting a lateral moving mechanism 40 and a longitudinal moving mechanism 50. By setting a paper stack positioning detection mechanism 60 electrically connected to the lateral moving mechanism 40, the paper stack on the paper stack conveyor 30 is positioned. Then, the paper stack positioning detection mechanism 60 controls the lateral moving mechanism 40 to move the paper stack conveyor 30 laterally, thereby centering the paper stack. This allows the bidirectional paper stack moving device 1 to integrate the functions of "lateral correction + longitudinal transfer + conveying" simultaneously, eliminating the need for multiple devices to be used together, improving transfer efficiency and reducing equipment costs.

[0024] Furthermore, the paper stack positioning detection mechanism 60 includes a paper stack detection element 61 and a paper stack distance detection element 62. The paper stack detection element 61 is disposed on one end of the support member 10 and located near the paper stack input end of the paper stack conveying mechanism 30. The paper stack distance detection element 62 is disposed on the other end of the support member 10 and faces the conveying surface 301 of the paper stack conveying mechanism 30. The paper stack distance detection element 62 is electrically connected to the lateral moving mechanism 40, and the paper stack detection element 61 is electrically connected to the longitudinal moving mechanism 50. Specifically, the paper stack detection element 61 can be, for example, a photoelectric sensor or a laser emitter. The laser emitter can be disposed on one end of the support member 10, and a reflector can be disposed on the corresponding other end. The laser emitter emits a light signal, which is then reflected by the reflector. Simultaneously, the laser emitter also has a light signal receiving function, meaning it can also receive the light signal reflected by the reflector. The paper stack detection component 61 is positioned near the paper stack input end of the paper stack conveying mechanism 30. This allows for the determination of whether the paper stack has fully entered and been placed on the conveying mechanism. Specifically, a laser emitter emits reflective laser light or other light rays, such as infrared or ultraviolet light. When the paper stack has not yet entered the conveying mechanism 30, the light signal emitted by the laser emitter is reflected by a reflector at the other end, allowing the laser emitter to receive the reflected light signal. When the paper stack begins to enter the conveying mechanism 30, the laser emitted by the laser emitter is blocked, preventing it from being reflected by the reflector. Therefore, the laser emitter cannot receive the reflected light signal at this time. The bidirectional paper stack movement device 1 then knows that the paper stack has entered the conveying mechanism 30 and does not perform distance judgment or correction. When the receiver changes from not being able to receive the reflected light signal to being able to receive it, the bidirectional paper stack movement device 1 can determine that the paper stack has been completely transferred and placed on the conveying mechanism 30. The paper stack distance detection element 62 can be, for example, a photoelectric distance sensor, which is disposed on the side of the support member 10 and located within the parallel line of the paper stack conveying mechanism 30. Then, two photoelectric distance sensors disposed on both sides of the support member 10 collect the distance from the left side of the paper stack to the left photoelectric distance sensor and the distance from the right side of the paper stack to the right photoelectric distance sensor, respectively, and transmit the two distance data to the processor. The processor compares the two distance data and obtains the following results: 1. When the distance data on the left side is large, it is determined that the paper stack is in a state of being biased to the right on the paper stack conveying mechanism. At this time, the lateral movement mechanism 40 is controlled to correct the deviation to the left until the distance data on the left side is equal to the distance data on the right side. 2. When the distance data on the right is large, it is determined that the paper stack is in a state of being too far to the left on the paper stack conveying mechanism. At this time, the lateral movement mechanism 40 is controlled to correct the deviation to the right until the distance data on the left and right are equal. 3. When the distance data on the left side is the same as the distance data on the right side, it is determined that the paper stack is in a centered state on the paper stack conveying mechanism, and no processing is performed at this time.

[0025] By cooperating with the paper stack detection component 61 and the paper stack distance detection component 62, the centering and transfer processing of the paper stack can be further realized.

[0026] Furthermore, the bidirectional paper stack moving device 1 also includes a positioning detection contact 71, which is disposed on one end of the support 10 near the paper stack conveying mechanism 30 and electrically connected to the paper stack distance detection device 62. The positioning detection contact 71 can be, for example, a positioning detection contact switch. Baffles are provided on both sides of the paper stack conveying mechanism 30. When the baffles of the paper stack conveying mechanism 30 move to the positioning detection contact 71, the switch of the positioning detection contact 71 is opened. At this time, the bidirectional paper stack moving device 1 can determine that the paper stack conveying mechanism 30 is in the middle position of the support 10, and does not control the lateral moving mechanism 40 to move the paper stack conveying mechanism 30. Of course, in other embodiments, a positioning detection contact switch can be provided near the left side and near the right side of the support 10 to prevent the paper stack conveying mechanism 30 from moving laterally to the edge of the support 10, that is, to prevent the paper stack conveying mechanism 30 from moving excessively.

[0027] Furthermore, the lateral movement mechanism 40 includes a chain drive component 41 and a lateral movement drive component 42. The chain drive component 41 is electrically connected to the lateral movement drive component 42. The lateral movement drive component 42 is disposed on one end of the support member 10. The chain drive component 41 is disposed on the side of the support member 10 away from the ground rail 20 and is drively connected to the paper stack conveying mechanism 30. The chain drive component 41 may be, for example, a chain, and the lateral movement drive component 42 may be, for example, a drive motor or a stepper motor, such as... Figure 2 As shown, a paper stack conveying mechanism connecting plate 44 is connected above the chain drive component 41. The paper stack conveying mechanism connecting plate 44 is fixedly connected to the paper stack conveying mechanism 30. The chain drives the paper stack conveying mechanism connecting plate 44 to move in the X direction, thereby driving the paper stack conveying mechanism 30 to move in the X direction. This achieves the lateral movement of the paper stack bidirectional moving device 1 in the horizontal direction.

[0028] Furthermore, the lateral movement mechanism 40 also includes a guide rail guide 43, which is disposed on the side of the support member 10 away from the ground rail 20 and adjacent to the chain drive member 41. The guide rail guide 43 may be, for example, a linear guide rail, which provides guidance and support for the lateral movement of the paper stack conveying mechanism 30.

[0029] Furthermore, the longitudinal movement mechanism 50 includes a longitudinal movement drive 51 and a first sliding member 52. The longitudinal movement drive 51 is electrically connected to the first sliding member 52, and the first sliding member 52 corresponds to and is slidably connected to the ground rail 20. The longitudinal movement drive 51 may be, for example, a DC motor or a drive motor, the first sliding member 52 may be, for example, a roller, and the ground rail 20 may be, for example, a protruding track with a central protrusion towards the support member 10. The roller is correspondingly disposed on the track to drive the entire support member to move along the Y direction.

[0030] Furthermore, the ground rails 20 include at least two rails, symmetrically distributed on both sides of the bottom of the support member 10. The longitudinal moving mechanism 50 also includes a limiting member 54 and a second sliding member 53. The limiting member 54 is disposed on the first sliding member 52, and the first sliding member 52 and the second sliding member 53 are drivenly connected. The first sliding member 52 is located on one of the two ground rails 20, and the second sliding member 53 is located on the other of the two ground rails 20. The first sliding member 52 may be, for example, a driving roller, and the second sliding member 53 may be, for example, a driven roller. The driving roller is connected to the driven roller through a linkage rod, thereby enabling the drive motor to drive the driving roller to roll, and the driving roller to drive the driven roller to roll. The limiting member 54 may be, for example, a limiting baffle. Since the ground rail 20 may be, for example, a protruding track with a protrusion in the middle facing the support member 10, limiting baffles are provided on both sides of the roller to prevent the driving roller from slipping off the track, so that the first sliding member 52 always slides on the ground rail 20. Ensure that the longitudinal movement of the support component 10 and the paper stack conveying mechanism 30 is stable and reliable.

[0031] A support plate 11 is provided at the end of the support member 10 away from the ground rail 20, and the support plate 11 is fixedly connected to the paper stack conveying mechanism 30. By providing the support plate 11, the paper stack conveying mechanism 30 can be further supported, thereby further ensuring the stability of the paper stack conveying mechanism 30 during conveying.

[0032] Furthermore, the bidirectional paper stack moving device 1 also includes a cable chain component 72, which is disposed on one side of the support component 10. The cable chain component 72 can be, for example, a complete cable chain, which is composed of numerous unit links, resembling a tank track. Each link can typically be opened to facilitate pipeline installation. By providing the cable chain component 72, the reciprocating cables in the bidirectional paper stack moving device 1 can be pulled, protected, and stored.

[0033] The specific working principle of this embodiment is as follows: First, the paper stack enters through the feed end of the paper stack conveying mechanism 30. Because the laser emitted by the laser emitter is blocked, the laser cannot be reflected by the reflector. That is, the laser emitter cannot receive the reflected light signal at this time. The paper stack detection component 61 can determine that the paper stack has entered the paper stack conveying mechanism 30. When the paper stack has completely entered the conveying surface 301 of the paper stack conveying mechanism 30, the paper stack detection component 61 changes from not receiving the reflected photoelectric signal to being able to receive the reflected photoelectric signal. The paper stack detection component 61 sends a feedback signal to the paper stack bidirectional moving device 1. The paper stack bidirectional moving device 1 obtains from the feedback signal that the paper stack has completely entered the paper stack conveying mechanism 30.

[0034] Then, the paper stack positioning detection mechanism 60 uses the paper stack distance detection element 62 to detect in real time whether the paper stack is centered on the paper stack conveying mechanism 30. The specific judgment process is as follows: 1. When the left distance data is large, it is determined that the paper stack is in a rightward state on the paper stack conveying mechanism 30. At this time, the lateral movement mechanism 40 sends a signal, and the lateral movement drive 42 drives the chain drive 41 to drive, so that the paper stack conveying mechanism 30 moves to the left along the guide rail guide 43 to correct the deviation until the left distance data is equal to the right distance data. 2. When the distance data on the right side is large, it is determined that the paper stack is in a state of being too far to the left on the paper stack conveying mechanism 30. At this time, the lateral movement mechanism 40 sends a signal, and the lateral movement drive 42 drives the chain drive 41 to drive, so that the paper stack conveying mechanism 30 corrects itself to the right along the guide rail guide 43 until the distance data on the left side is equal to the distance data on the right side. 3. When the distance data on the left side is the same as the distance data on the right side, it is determined that the paper stack is in a centered state on the paper stack conveying mechanism 30, and no processing is performed at this time.

[0035] When longitudinal transfer is required, the longitudinal movement drive 51 of the longitudinal movement mechanism 50 drives the first sliding member 52 to slide on the ground rail 20, and the first sliding member 52 drives the second sliding member 53 to slide on the ground rail 20, so that the support member 10 moves longitudinally along the ground rail 20, and transfers the paper stack to the target workstation or target device.

[0036] Furthermore, it is understood that the foregoing embodiments are merely illustrative examples of this utility model. Provided that the technical features do not conflict, the structure is not contradictory, and the utility model's objective is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
