Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a track switching device and material conveying equipment. Background Art

[0002] Rail logistics transportation systems are widely used in hospitals, libraries and other places, changing the traditional way of transporting items, medicines, blood samples and instruments by nurses or administrators through elevators.

[0003] The transmission structure of the transfer device in the related art relies on processing accuracy to ensure the reliability of transmission, resulting in increased production. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] In view of this, in the first aspect, the utility model proposes a track switching device, including: a support base; a tray, on which is provided at least one track switching track; a driving member connected to the tray; a gear portion drivingly connected to the driving member; a rack connected to the support base, the gear portion meshing with the rack; a guide assembly connected to the tray, and the guide assembly being slidably connected to the support base.

[0006] The rack is installed on the support seat, and the position of the rack remains unchanged. The driving member is used to drive the gear part to rotate, and the gear part is meshed with the rack. When the gear part rotates, since the position of the rack does not move, the gear part will move relative to the rack when rotating. The gear part and the driving member are connected, so the driving member and the gear part can move synchronously relative to the rack. The driving member is installed on the tray. When the driving member moves, the driving member drives the tray to move relative to the rack, thereby realizing the track changing function. The gear part and the rack cooperate with each other to drive the tray to move left and right. The gear part and the rack are used as driving structures, and the transmission process is more reliable. In addition, the installation accuracy is low, which is conducive to reducing the cost of the track changing device.

[0007] The guide assembly is connected to the pallet. When the pallet moves, the guide assembly moves relative to the support seat. The guide assembly can slide along the support seat. Therefore, the support seat can guide the guide assembly to ensure that the guide assembly can only move in the specified direction, prevent the pallet from offsetting when moving, and ensure that the pallet can accurately move to the specified position. Moreover, by adding the guide assembly, the phenomenon of the pallet moving being stuck due to processing and installation precision errors can be avoided, thereby achieving accurate and stable movement of the pallet.

[0008] A track-changing track is set on the pallet. If the logistics vehicle has a need to change tracks, the driving component drives the pallet to move to a position facing the logistics vehicle, and the material vehicle can move to the track-changing track. The driving component drives the pallet to move again. When the track-changing track moves to the target position, the logistics vehicle can move from the track-changing track to the target track. There can be at least one track-changing track on the pallet. For example, if multiple material vehicles have a need to change tracks at the same time, the number of track-changing tracks can be set to multiple, so that multiple material vehicles can move to different track-changing tracks respectively.

[0009] In addition, the track switching device in the above technical solution provided by the utility model may also have the following additional technical features:

[0010] In some technical solutions, optionally, the transfer device also includes: a first mounting plate connected to the tray; a second mounting plate connected to the driving member, and the second mounting plate is detachably connected to the first mounting plate.

[0011] The driving member is indirectly fixed to the tray through the second mounting plate and the first mounting plate. The second mounting plate can be removed from the first mounting plate, so that the driving member can be easily disassembled and assembled, which is beneficial to improving the convenience of disassembly and assembly of the driving member and facilitating maintenance of the driving member and the gear part.

[0012] In some technical solutions, optionally, a mounting hole is set on one of the first mounting plate and the second mounting plate, and a strip hole is set on the other; the track switching device also includes: a locking piece, which passes through the mounting hole and the strip hole to lock the second mounting plate to the first mounting plate.

[0013] By passing the locking piece through the mounting hole and the strip hole, the first mounting plate and the second mounting plate can be locked to each other. The locking piece can move in the strip hole, so that the relative position of the first mounting plate and the second mounting plate can be adjusted, and then the mounting position of the driving piece and the gear part can be adjusted. The gear part can be adjusted to a configuration that stably matches with the rack, ensuring that the gear part and the rack can accurately match.

[0014] In some technical solutions, optionally, the track transfer device also includes: a plurality of first sensing members connected to the support seat, the plurality of first sensing members are spaced apart along the first direction, and the driving member is used to drive the tray to move along the first direction; a second sensing member connected to the guide assembly, the tray has a plurality of track changing positions, a track changing position corresponds to a first sensing member, and at the track changing position, the second sensing member is located within the sensing range of the first sensing member.

[0015] In the length direction of the rack, a plurality of first sensing elements are arranged on the support seat, one first sensing element corresponds to one track-changing position, and when the tray moves accurately to the track-changing position, the second sensing element is located within the sensing range of the first sensing element.

[0016] When changing tracks of the logistics trolley, it is necessary to ensure that the material pallet is accurately moved to the target track changing position. The moving position of the pallet can be controlled by the driving component. The first sensing component and the second sensing component are used for secondary feedback. After the driving component controls the movement of the pallet, if the first sensing component does not sense the second sensing component, it means that the pallet has not moved into place. At this time, the driving component can be controlled to continue to drive the pallet to operate, ensuring that the pallet can accurately move to the track changing position.

[0017] In some technical solutions, optionally, the transfer device also includes: a first limit position sensor connected to the support seat; a second limit position sensor connected to the guide assembly, when the tray moves to the limit position relative to the support seat, the second limit position sensor is located within the sensing range of the first limit position sensor.

[0018] During the process of the driving member driving the pallet to move, there may be a program error, or the first sensor and the second sensor may be damaged. Even if the pallet has moved to the track-changing position, the system believes that the pallet has not yet moved to the track-changing position, causing the driving member to continue to move the pallet. In order to prevent the guide assembly from detaching from the mounting seat, it is necessary to limit the maximum range of movement of the guide assembly.

[0019] A first limit position sensor is set on the support seat, and a second limit position sensor is set on the guide assembly. If the first limit position sensor senses the second limit position sensor, it means that the guide assembly has moved to the limit position. At this time, the system can control the drive component to stop running to prevent the guide assembly from detaching from the mounting seat, thereby avoiding damage to the transfer device.

[0020] In some technical solutions, optionally, the transfer device also includes: a limit member connected to the support seat, and when the tray passes the limit position, the guide assembly abuts against the limit member.

[0021] When the tray passes the limit position, the limiter is used to limit the guide assembly to prevent the guide assembly from moving further. Even if the first limit position sensor or the second limit position sensor is damaged, the limiter can limit the guide assembly to the limit position to prevent the guide assembly from leaving the support seat.

[0022] The first limit position sensor and the second limit position sensor serve as the first layer limit position, and the limit piece serves as the second layer limit position. Through the two layers of restrictions, the guide assembly is effectively prevented from separating from the support seat, ensuring that the transfer device can operate stably and avoiding damage to the transfer device due to excessive movement of the guide assembly.

[0023] In some technical solutions, optionally, the support seat includes: a guide rail; the guide assembly includes: a slider group connected to the tray, and the slider group is slidably connected to the guide rail.

[0024] The slider group can slide along the guide rail, and the guide rail guides the slider group so that the tray can stably move between different track change positions.

[0025] In some technical solutions, optionally, the guide assembly also includes: a friction block connected to the tray, the friction block and the slider group are distributed along the length direction of the track change track, the friction block and the slider group support the tray, the support seat is provided with a slide groove, and the friction block is slidably connected to the slide groove.

[0026] The friction block and the slider group can slide along the support seat, and the friction block and the slider group are distributed in the length direction of the track change track, so that the friction block and the slider group support the pallet together, and the forces on both sides of the pallet are balanced, ensuring that the pallet can move stably relative to the support seat, thereby improving the stability of the pallet when moving.

[0027] The guide rail can guide the guide component stably. On this basis, the friction block can be matched with the slide groove. The structure of the friction block and the slide groove has a lower processing cost than the guide rail. For example, the guide rail can mainly play a guiding function, and the friction block mainly plays a supporting role.

[0028] In some technical schemes, optionally, the support seat also includes: a supporting profile, the guide rail is connected to the supporting profile, the supporting profile and the rack extend in the same direction, and the supporting profile is distributed on both sides of the length direction of the track changing track; a connecting plate, the two ends of the connecting plate are respectively connected to the guide rails on both sides of the length direction of the track changing track, and the rack is connected to the connecting plate.

[0029] Along the length direction of the track-changing track, support profiles are arranged on both sides of the track-changing track, the guide rail is arranged on one support profile, and the slide groove is arranged on the other support profile.

[0030] The connecting plate is used to connect two supporting profiles, so the connecting plate and the supporting profile are combined to form a supporting frame, which can be installed as a whole at the installation position, and other devices in the track changing device can be installed on the supporting frame, so that the track changing track is an integral structure, which is convenient for installing the track changing track.

[0031] In a second aspect, the utility model provides a material conveying equipment, including: a track switching device as in the first aspect.

DETAILED DESCRIPTION

[0044] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0046] Refer to the following Figures 1 to 8 The invention describes a track switching device and material conveying equipment provided according to some embodiments of the invention.

[0047] like Figure 1 As shown, in an embodiment of the utility model, a track switching device is proposed, including: a support base 100, a tray 200, a driving member 300, a gear part 400, a rack 500 and a guide assembly 600, wherein the tray 200 is provided with at least one track switching track 210, the driving member 300 is connected to the tray 200, and the gear part 400 is drivingly connected to the driving member 300. The rack 500 is connected to the support base 100, the gear part 400 is meshed with the rack 500, the guide assembly 600 is connected to the tray 200, and the guide assembly 600 is slidably connected to the support base 100.

[0048] The rack 500 is mounted on the support seat 100, and the position of the rack 500 remains unchanged. The driving member 300 is used to drive the gear part 400 to rotate, and the gear part 400 is meshed with the rack 500. When the gear part 400 rotates, since the position of the rack 500 does not move, the gear part 400 will move relative to the rack 500 when rotating. The gear part 400 and the driving member 300 are connected, so the driving member 300 and the gear part 400 can move synchronously relative to the rack 500. The driving member 300 is mounted on the tray 200. When the driving member 300 moves, the driving member 300 drives the tray 200 to move relative to the rack 500, thereby realizing the track changing function. The gear part 400 and the rack 500 cooperate with each other to drive the tray 200 to move left and right. The gear part 400 and the rack 500 are used as a driving structure, and the transmission process is more reliable, and the installation accuracy is low, which is conducive to reducing the cost of the track changing device.

[0049] The guide assembly 600 is connected to the tray 200. When the tray 200 moves, the guide assembly 600 moves relative to the support base 100. The guide assembly 600 can slide along the support base 100. Therefore, the support base 100 can guide the guide assembly 600 to ensure that the guide assembly 600 can only move in a specified direction, prevent the tray 200 from offset during movement, and ensure that the tray 200 can accurately move to the specified position. Moreover, by adding the guide assembly 600, the phenomenon of the tray 200 being stuck due to processing and installation precision errors can be avoided, thereby achieving accurate and stable movement of the tray 200.

[0050] A track-changing track 210 is provided on the pallet 200. If the logistics vehicle has a need to change tracks, the driving member 300 drives the pallet 200 to move to a position directly opposite the logistics vehicle, and the material vehicle can move to the track-changing track 210. The driving member 300 drives the pallet 200 to move again. When the track-changing track 210 moves to the target position, the logistics vehicle can move from the track-changing track 210 to the target track. There can be at least one track-changing track 210 on the pallet 200. For example, if multiple material vehicles have a need to change tracks at the same time, the number of track-changing tracks 210 can be set to be multiple, so that multiple material vehicles can move to different track-changing tracks 210 respectively.

[0051] In a possible application, the gear portion 400 may be a gear, or the gear portion 400 includes a plurality of gears meshing with each other.

[0052] Exemplarily, the driving member 300 may be a motor 310 , or the driving member 300 may be a combination of a motor 310 and a reducer 320 .

[0053] Combination Figure 4 and Figure 5 As shown, in some embodiments, optionally, the transfer device also includes: a first mounting plate 710 and a second mounting plate 720, the first mounting plate 710 is connected to the tray 200, the second mounting plate 720 is connected to the driving member 300, and the second mounting plate 720 is detachably connected to the first mounting plate 710.

[0054] The driving member 300 is indirectly fixed to the tray 200 through the second mounting plate 720 and the first mounting plate 710. The second mounting plate 720 can be removed from the first mounting plate 710, so that the driving member 300 can be easily disassembled and assembled, which is beneficial to improving the convenience of disassembly and assembly of the driving member 300 and facilitating maintenance of the driving member 300 and the gear part 400.

[0055] The first mounting plate 710 can be locked on the bottom of the tray 200 by means of screws or the like, and the second mounting plate 720 can be locked on the driving member 300 by means of screws or the like.

[0056] Combination Figure 4 and Figure 5 As shown, in some embodiments, optionally, one of the first mounting plate 710 and the second mounting plate 720 is provided with a mounting hole 721, and the other is provided with a bar-shaped hole 711. The track switching device further includes: a locking member 730, which passes through the mounting hole 721 and the bar-shaped hole 711 to lock the second mounting plate 720 to the first mounting plate 710.

[0057] By passing the locking piece 730 through the mounting hole 721 and the strip hole 711, the first mounting plate 710 and the second mounting plate 720 can be locked to each other. The locking piece 730 can move in the strip hole 711, so that the relative position of the first mounting plate 710 and the second mounting plate 720 can be adjusted, and then the mounting position of the driving piece 300 and the gear part 400 can be adjusted. The gear part 400 can be adjusted to a configuration that stably cooperates with the rack 500, ensuring that the gear part 400 and the rack 500 can accurately cooperate.

[0058] Exemplarily, the locking member 730 includes a bolt and a nut, the bolt passes through the mounting hole 721 and the bar hole 711, and the nut is connected to the bolt.

[0059] Combination Figure 1 and Figure 3 As shown, in some embodiments, optionally, the track switching device further includes: a second sensing member 750 and a plurality of first sensing members 740, the first sensing member 740 is connected to the support seat 100, the plurality of first sensing members 740 are spaced apart along the first direction, and the driving member 300 is used to drive the tray 200 to move along the first direction. The second sensing member 750 is connected to the guide assembly 600, and the tray 200 has a plurality of track switching positions, one track switching position corresponds to one first sensing member 740, and at the track switching position, the second sensing member 750 is located within the sensing range of the first sensing member 740.

[0060] In the length direction of the rack 500 , a plurality of first sensing members 740 are disposed on the support base 100 , and one first sensing member 740 corresponds to one track-changing position. When the tray 200 accurately moves to the track-changing position, the second sensing member 750 is located within the sensing range of the first sensing member 740 .

[0061] When changing tracks of the logistics trolley, it is necessary to ensure that the material pallet 200 is accurately moved to the target track changing position. The moving position of the pallet 200 can be controlled by the driving member 300. The first sensing member 740 and the second sensing member 750 are used for secondary feedback. After the driving member 300 controls the movement of the pallet 200, if the first sensing member 740 does not sense the second sensing member 750, it means that the pallet 200 has not moved into place. At this time, the driving member 300 can be controlled to continue to drive the pallet 200 to operate, thereby ensuring that the pallet 200 can be accurately moved to the track changing position.

[0062] Exemplarily, the first sensing element 740 and the second sensing element 750 are distance sensors, or the first sensing element 740 and the second sensing element 750 are position sensors.

[0063] In a possible application, the first direction is the length direction of the rack 50 .

[0064] This embodiment provides a new type of track switching device, which has a simple structure, is easy to install, and has high reliability. The motor 310 drives the gear rack 500 to realize the flexible movement of the tray 200. The tray 200 can be accurately stopped at the corresponding position of the port, and a sensor is used to realize secondary positioning detection. When the tray 200 is in place, the logistics trolley can run onto the tray 200, and the tray 200 moves to the required position to realize the track switching of the logistics trolley.

[0065] When the logistics runs to the front of the transfer device, the controller issues an instruction to control the motor 310 to operate. The motor 310 drives the gear to rotate, and the gear and rack 500 engage to drive the tray 200 to move to the specified position, so that the tray 200 is aligned with the port track. After the tray 200 is in place, the first sensor 740 triggers the second sensor 750, and the in-place signal is fed back to the controller for secondary feedback. The controller sends an instruction to control the logistics trolley to advance to the tray 200 to avoid the phenomenon that the logistics trolley is stuck when the tray 200 is not in place. After receiving the in-place signal that the logistics trolley advances to the tray 200, the controller controls the gear to rotate and the tray 200 moves left and right to realize the track conversion of the trolley.

[0066] Combination Figure 7 and Figure 8 As shown, in some embodiments, optionally, the transfer device also includes: a first limit position sensor 760 and a second limit position sensor 770, the first limit position sensor 760 is connected to the support base 100, and the second limit position sensor 770 is connected to the guide assembly 600, when the tray 200 moves to the limit position relative to the support base 100, the second limit position sensor 770 is located within the sensing range of the first limit position sensor 760.

[0067] During the process of the driving member 300 driving the tray 200 to move, a program error may occur, or the first sensing member 740 and the second sensing member 750 may be damaged. Even if the tray 200 has moved to the track-changing position, the system believes that the tray 200 has not yet moved to the track-changing position, causing the driving member 300 to drive the tray 200 to continue to move. In order to prevent the guide assembly 600 from detaching from the mounting seat, it is necessary to limit the maximum range of movement of the guide assembly 600.

[0068] A first limit position sensor 760 is set on the support seat 100, and a second limit position sensor 770 is set on the guide assembly 600. If the first limit position sensor 760 senses the second limit position sensor 770, it means that the guide assembly 600 has moved to the limit position. At this time, the system can control the driving member 300 to stop running to prevent the guide assembly 600 from detaching from the mounting seat, thereby avoiding damage to the transfer device.

[0069] Exemplarily, the first limit position sensor 760 and the second limit position sensor 770 are distance sensors, or the first induction element 740 and the second induction element 750 are position sensors.

[0070] like Figure 1 As shown, in some embodiments, optionally, the transfer device further includes: a limit member 780 connected to the support seat 100 , and when the tray 200 exceeds the limit position, the guide assembly 600 abuts against the limit member 780 .

[0071] When the tray 200 exceeds the limit position, the limiter 780 is used to limit the guide assembly 600 and restrict the guide assembly 600 from continuing to move. Even if the first limit position sensor 760 or the second limit position sensor 770 is damaged, the limiter 780 can be used to limit the guide assembly 600 to prevent the guide assembly 600 from detaching from the support base 100.

[0072] The first limit position sensor 760 and the second limit position sensor 770 serve as the first layer limit position, and the limit member 780 serves as the second layer limit position. The two layers of limit can effectively prevent the guide assembly 600 from separating from the support seat 100, thereby ensuring that the transfer device can operate stably and preventing the transfer device from being damaged due to excessive movement of the guide assembly 600.

[0073] The surface of the limiter 780 may be provided with a surface structure of a softer material, for example, a silicone member or a rubber member may be provided on the surface of the limiter 780, so that when the guide assembly 600 hits the limiter 780, it is not easy to cause damage to the guide assembly 600.

[0074] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the support seat 100 includes: a guide rail 110 , and the guide assembly 600 includes: a slider group 610 , the slider group 610 is connected to the tray 200 , and the slider group 610 is slidably connected to the guide rail 110 .

[0075] The slider group 610 can slide along the guide rail 110 , and the guide rail 110 guides the slider group 610 , so that the tray 200 can stably move between different track-changing positions.

[0076] The slider group 610 includes a first fixing plate 611 and a slider 612 . The first fixing plate 611 is locked to the bottom of the tray 200 by means of screws and other components. The slider 612 is mounted on the first fixing plate 611 . The slider 612 is slidably connected to the guide rail 110 .

[0077] Combination Figure 4 and Figure 6As shown, in some embodiments, optionally, the guide assembly 600 also includes: a friction block 620, the friction block 620 is connected to the tray 200, the friction block 620 and the slider group 610 are distributed along the length direction of the track change track 210, the friction block 620 and the slider group 610 support the tray 200, the support seat 100 is provided with a slide groove 120, and the friction block 620 is slidably connected to the slide groove 120.

[0078] The friction block 620 and the slider group 610 can slide along the support seat 100, and the friction block 620 and the slider group 610 are distributed in the length direction of the track change track 210, so that the friction block 620 and the slider group 610 support the tray 200 together, and the forces on both sides of the tray 200 are balanced, ensuring that the tray 200 can stably move relative to the support seat 100, thereby improving the stability of the tray 200 when moving.

[0079] The guide rail 110 can guide the guide assembly 600 stably. On this basis, the friction block 620 can be matched with the slide groove 120. The structure in which the friction block 620 and the slide groove 120 are matched has a lower processing cost than the guide rail 110. For example, the guide rail 110 can mainly play a guiding function, and the friction block 620 can mainly play a supporting role.

[0080] Of course, in other embodiments, both sides of the tray 200 may be supported by the slider group 610 , that is, the guide rails 110 are on both sides, and one guide rail 110 is matched with one slider group 610 .

[0081] The friction block 620 includes a second fixed plate 621 and a sliding plate 622 . The second fixed plate 621 is locked to the bottom of the tray 200 by screws and other components. The sliding plate 622 is installed on the second fixed plate 621 . The sliding plate 622 is slidably connected to the sliding groove 120 .
