Description

Technical Field

[0001] This disclosure relates to the technical field of automated loading and unloading equipment, and in particular to a pallet support device and a pallet lifting support assembly. Background Technology

[0002] Pallets are commonly used as containers for loading and unloading materials in automated production lines. However, pallets will deform after a period of use, and the existing pallet support devices have a limited effective support area. This makes it difficult for the pallet support devices to stably support the pallet, which may cause the pallet to tilt during loading and unloading, and in severe cases, even lead to the risk of pallet collision with the machine.

[0003] In view of this, there is an urgent need in the market for a pallet support device that provides stable and reliable support and can provide limited support for multiple parts of the pallet. Utility Model Content

[0004] This disclosure provides a pallet support device and a pallet lifting support assembly to address the problems in related technologies where the effective support area for pallets is limited and the support stability for deformed pallets is poor.

[0005] The pallet support device provided in this embodiment includes a mounting base plate, a driver, a moving part, a pallet support plate, and a transmission assembly; The driver is disposed on the mounting substrate; The movable component is connected to the driver and is capable of reciprocating toward or away from the driver under the drive of the driver; The tray support plate is rotatably disposed above the mounting base plate and has a support portion for supporting the tray; A transmission assembly is disposed between the moving part and the pallet support plate, and drives the two together. When the moving component reciprocates, the transmission assembly can synchronously drive the support portion in the pallet support plate to rotate toward or away from the mounting base plate, so as to adjust the support angle state of the pallet support plate.

[0006] In one embodiment, the transmission assembly includes a transmission rack, a rotating shaft, and a transmission gear; The transmission rack is disposed in the moving part and can reciprocate synchronously with the moving part; The rotating shaft is rotatably disposed above the mounting base plate; The transmission gear is fixedly fitted onto the outer periphery of the rotating shaft and meshes with the transmission rack. One side of the pallet support plate is fixedly connected to the outer periphery of the rotating shaft; When the transmission rack moves back and forth, it can correspondingly drive the transmission gear, the rotating shaft, and the tray support plate to rotate back and forth around the axis of the rotating shaft.

[0007] In one embodiment, the mounting base plate is further provided with a plurality of fixing members protruding therefrom; Both ends of the rotating shaft are mounted in the fixing component via bearings.

[0008] In one embodiment, the pallet support plate includes at least two support portions spaced apart from each other, and a first clearance opening is formed between the two support portions; When the support rotates toward the mounting base plate, the first clearance can correspondingly avoid a portion of the structure in the moving member.

[0009] In one embodiment, the tray support plate near the rotating shaft is further provided with a hollowed-out second clearance opening; When the support rotates toward the mounting base plate, the second clearance opening can correspondingly avoid the transmission rack.

[0010] In one embodiment, the pallet support plate is provided with a resistance-increasing element in the support portion to improve the stability of the pallet support.

[0011] In addition, this disclosure also provides a pallet lifting support assembly, which includes a mounting frame and the pallet support device described above; The mounting bracket includes a guide member arranged in the vertical direction; The mounting base plate is movably connected to the guide member and can reciprocate up and down relative to the guide member in the vertical direction to adjust the support height of the tray support plate in the mounting frame.

[0012] In one possible embodiment, the mounting bracket is further provided with a lifting drive; The lifting driver is connected to the mounting base plate for driving the mounting base plate to move up and down along the guide member, and for locking and fixing the mounting base plate at any position in the guide member.

[0013] In one possible embodiment, the guide includes a lead screw arranged in a vertical direction; The mounting base plate has a through mounting hole, and a nut that is screwed into the mounting hole is also provided therein for connection with the lead screw; The lifting driver is connected to the guide member and can drive the lead screw to reciprocate around its own axis, so that the mounting base plate moves up and down along the guide member under the drive of the nut.

[0014] In one embodiment, multiple pallet support devices are provided in the mounting frame, and at least two of the pallet support devices are symmetrically distributed about the central axis of the mounting frame.

[0015] The technical solution provided in this disclosure has the following advantages compared with related technologies: The pallet support device provided in this embodiment can change the actual support angle of the support part in the pallet support plate by driving the moving part to move back and forth through a driver. In this way, when the support part supports the bottom of the pallet, it can compensate for the rotation according to the tilt deformation angle of the bottom of the pallet, so as to ensure that the support part in the pallet support plate can always form a sufficiently large support contact area with the bottom of the pallet, thus ensuring the support stability of the pallet support device for the pallet.

[0016] In addition, after the pallet support device is used up, the support part in the pallet support plate rotates toward the mounting base and enters the storage state, thereby saving the space occupied by the pallet support device when it is stored.

[0017] In addition, this disclosure also provides a pallet lifting support assembly, which includes the pallet support device described above, and can achieve all the beneficial effects of the pallet support device described above, which will not be described in detail here.

[0022] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0024] Combination Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides a pallet support device, which includes a mounting base plate 1, a driver 2, a movable member 3, a pallet support plate 5, and a transmission assembly 4; the driver 2 is disposed on the mounting base plate 1; the movable member 3 is connected to the driver 2 and can reciprocate toward or away from the driver 2 under the drive of the driver 2; the pallet support plate 5 is rotatably disposed above the mounting base plate 1 and has a support portion 51 for supporting the pallet; the transmission assembly 4 is disposed between the movable member 3 and the pallet support plate 5 and drives the two together; wherein, when the movable member 3 reciprocates, the transmission assembly 4 can synchronously drive the support portion 51 in the pallet support plate 5 to rotate toward or away from the mounting base plate 1, so as to adjust the support angle state of the pallet support plate 5.

[0025] The pallet support device provided in this disclosure can be applied, but is not limited to, to pallet support and transportation in various automated production lines.

[0026] In practical use, the pallet support device first places the mounting base 1 in the installation station or conveyor line. Then, the driver 2 drives the moving part 3 to move away from the driver 2. At this time, the transmission component 4 transmits the movement of the moving part 3 to the pallet support plate 5 above the mounting base 1, causing the support part 51 in the pallet support plate 5 to rotate away from the mounting base 1 and enter the required support angle state. For example, when the mounting base 1 is set in a horizontal direction, the pallet support plate 5 can also rotate to a horizontal direction, so that the support part 51 can support the bottom of the pallet in a horizontal direction. Moreover, if the bottom of the pallet develops a certain tilting deformation after long-term use, the pallet support plate 5 can drive the support part 51 to rotate to a certain angle in the horizontal direction (e.g., but not limited to ±2°, ±5°, ±10°, etc.) to compensate for the tilting deformation of the bottom of the pallet, thereby ensuring that the support part 51 in the pallet support plate 5 can always form a sufficiently large support contact area with the bottom of the pallet, ensuring the stability of the pallet support.

[0027] Furthermore, when the pallet support device is no longer needed after use, the driver 2 can drive the moving part 3 to move toward the driver 2 to reset. At this time, the transmission component 4 can also transmit the reset movement of the moving part 3 to the pallet support plate 5 above the mounting base plate 1, and make the support part 51 in the pallet support plate 5 rotate toward the mounting base plate 1 to enter the storage state, saving the space occupied by the pallet support device when it is not in use.

[0028] In addition, it is worth noting that multiple pallet support plates 5 can be spaced apart above the mounting base plate 1, and the multiple pallet support plates 5 can be configured to rotate independently of each other. In this way, the multiple support parts 51 in the multiple pallet support plates 5 can form multi-point and multi-angle support for the bottom of the pallet, which fully ensures that all parts of the bottom of the pallet can be stably supported over a large area.

[0029] Furthermore, the aforementioned driver 2 may be equipped with, but is not limited to, devices with driving functions such as drive cylinders and drive motors. The aforementioned transmission assembly 4 can convert the translation of the moving part 3 into the rotation of the tray support plate 5; therefore, the aforementioned transmission assembly 4 may be configured as, but is not limited to, a "gear and rack transmission mechanism" or a "screw and nut transmission mechanism".

[0030] In one embodiment, the transmission assembly 4 includes a transmission rack 41, a rotating shaft 42, and a transmission gear 43; the transmission rack 41 is disposed in the moving member 3 and can reciprocate synchronously with the moving member 3; the rotating shaft 42 is rotatably disposed above the mounting base plate 1; the transmission gear 43 is fixedly fitted on the outer periphery of the rotating shaft 42 and meshes with the transmission rack 41; wherein, one side of the tray support plate 5 is fixedly connected to the outer periphery of the rotating shaft 42; when the transmission rack 41 reciprocates, it can correspondingly drive the transmission gear 43, the rotating shaft 42, and the tray support plate 5 to reciprocate around the axis of the rotating shaft 42.

[0031] Specifically, in combination Figure 1 and Figure 2 In further detail, the transmission assembly 4 is configured to include a transmission rack 41, a rotating shaft 42, and a transmission gear 43. The transmission rack 41 can be fixedly installed in the moving member 3, the rotating shaft 42 can be rotatably installed above the mounting base plate 1, and the transmission gear 43 is fixedly fitted onto the outer periphery of the rotating shaft 42 and meshes with the transmission rack 41. In this way, when the moving member 3 reciprocates under the drive of the driver 2, the transmission rack 41 can synchronously drive the transmission gear 43 and the rotating shaft 42 to reciprocate around the axis of the rotating shaft 42.

[0032] Furthermore, since one side of the pallet support plate 5 is fixedly connected to the outer periphery of the rotating shaft 42, when the rotating shaft 42 reciprocates, the pallet support plate 5 can also reciprocate synchronously, thereby realizing the function of driving the support part 51 in the pallet support plate 5 to reciprocate toward or away from the mounting base plate 1.

[0033] The transmission component 4 described above has a simple structure, can flexibly and stably drive the support part 51 to reciprocate, and can also self-lock and fix the support part 51 when it rotates to any angle.

[0034] In one embodiment, a plurality of fasteners 11 are also provided in the mounting base plate 1; the two ends of the rotating shaft 42 are respectively mounted in the fasteners 11 by bearings.

[0035] Specifically, in combination Figure 1 and Figure 2 In further detail, the aforementioned fixing member 11 may be configured to vertically protrude from multiple fixing posts in the mounting base plate 1, and a corresponding mounting gap may be formed between two fixing members 11 so that both ends of the rotating shaft 42 are vertically inserted into the fixing member 11 through bearings, thereby realizing the function of rotatably setting the rotating shaft 42 above the mounting base plate 1.

[0036] The specific arrangement of the aforementioned fastener 11 has the advantages of simple structure and stable installation of the rotating shaft 42 in a rotatable and limited manner.

[0037] In one embodiment, the tray support plate 5 includes at least two support portions 51 spaced apart from each other, and a first clearance opening 52 is formed between the two support portions 51; when the support portion 51 rotates toward the mounting base plate 1, the first clearance opening 52 can correspondingly avoid a part of the structure in the moving member 3.

[0038] Specifically, in combination Figure 1 and Figure 2 In further detail, the two support parts 51 in the pallet support plate 5 can be correspondingly arranged on the side of the pallet support plate 5 away from the rotation axis 42, and a hollow first clearance opening 52 can be formed between the two support parts 51. In this way, when the support part 51 rotates toward the mounting base plate 1, the first clearance opening 52 can allow part of the structure in the moving part 3 to pass through, so as to achieve the function of avoiding the moving part 3. In this way, when the pallet support device is in the storage state, the pallet support plate 5 can be stored closer to the moving part 3, further reducing the space occupied in the storage state.

[0039] In one embodiment, the tray support plate 5 near the rotating shaft 42 is also provided with a hollowed-out second clearance opening 53; when the support part 51 rotates toward the mounting base plate 1, the second clearance opening 53 can correspondingly avoid the transmission rack 41.

[0040] Specifically, in combination Figure 1 and Figure 2 In further detail, a second clearance opening 53 is provided in the plate body of the pallet support plate 5 near the rotating shaft 42. When the support part 51 rotates toward the mounting base plate 1, the second clearance opening 53 can be used to allow the transmission rack 41 to pass through, so as to avoid the transmission rack 41. In this way, the reciprocating rotation of the pallet support plate 5 and the reciprocating movement of the transmission rack 41 can be avoided to prevent motion interference, ensuring that the pallet support plate 5 can always perform normal reciprocating rotation.

[0041] In one embodiment, the pallet support plate 5 is provided with a resistance-increasing element 511 in the support portion 51 to improve the stability of the pallet support.

[0042] Specifically, in combination Figure 3 In further detail, the aforementioned friction-enhancing element 511 can be, but is not limited to, a rubber pad, and friction-enhancing textures can be further provided on the surface of the rubber pad. In this way, the support part 51 can make contact with the bottom of the tray through the friction-enhancing element 511. On the one hand, it can increase the frictional resistance between the two, and on the other hand, the friction-enhancing element 511 also has a certain elastic deformation capability, which can further fill and compensate for the small gap between the support part 51 and the bottom of the tray, thereby further improving the support stability of the tray support plate 5 for the tray.

[0043] Additionally, when the tray is made of an iron-containing material, the friction-increasing component 511 can also be configured as a magnetic component. The magnetic attraction of the magnetic component can further increase the frictional resistance between the tray support plate 5 and the tray, thereby improving support stability.

[0044] In addition, this disclosure also provides a pallet lifting support assembly, which includes a mounting frame 6 and the pallet support device described above; wherein, the mounting frame 6 includes a guide member 61 arranged in the vertical direction; the mounting base plate 1 is movably connected to the guide member 61 and can reciprocate up and down relative to the guide member 61 in the vertical direction to adjust the support height of the pallet support plate 5 in the mounting frame 6.

[0045] Specifically, in combination Figure 4 In further detail, the mounting frame 6 in the pallet lifting support assembly can be, but is not limited to, a cubic shape, and the aforementioned pallet support device can be correspondingly installed in the bottom or lower half of the mounting frame 6. Furthermore, since the mounting frame 6 includes a guide member 61 arranged in the vertical direction, the mounting base plate 1 can reciprocate vertically relative to the guide member 61, thereby adjusting the support height of the pallet support plate 5 within the mounting frame 6, making the pallet support device suitable for more working conditions.

[0046] Furthermore, since the pallet lifting support assembly includes the aforementioned pallet support device, it can achieve all the beneficial effects of the aforementioned pallet support device, which will not be elaborated further here.

[0047] In one embodiment, the mounting bracket 6 is further provided with a lifting driver 62; the lifting driver 62 is connected to the mounting base plate 1 for driving the mounting base plate 1 to move up and down along the guide member 61, and locking the mounting base plate 1 at any position in the guide member 61.

[0048] Specifically, in combination Figure 4 In further detail, the aforementioned lifting driver 62 can be, but is not limited to, a drive motor, and the lifting driver 62 can be connected to the mounting base plate 1 in various ways. For example, the functions of driving the mounting base plate 1 to move up and down along the guide member 61 and locking the mounting base plate 1 at any position in the guide member 61 can be realized by means of "drive motor + take-up and put-out reel + traction line", "drive motor + gear and rack transmission mechanism", "drive motor + lead screw and nut transmission mechanism", etc.

[0049] In one embodiment, the guide member 61 includes a lead screw arranged in a vertical direction; the mounting base plate 1 has a through mounting hole 12, and a nut that is screwed and fitted with the lead screw is also provided in the mounting hole 12; wherein, the lifting drive 62 is connected to the guide member 61 in a transmission connection, and can drive the lead screw to reciprocate around its own axis, so that the mounting base plate 1 moves up and down along the guide member 61 under the drive of the nut.

[0050] Specifically, multiple guide members 61 can be set in the mounting bracket 6. One or more guide members 61 can be set as lead screws, and the remaining guide members 61 can be set as smooth guide rods. Nuts are fixedly set in the mounting holes 12 of the mounting base plate 1, and the nuts are screwed onto the outer periphery of the lead screw. In this way, a "lead screw and nut transmission mechanism" is formed between the guide member 61 and the mounting base plate 1. When the lifting driver 62 drives the lead screw to reciprocate around its own axis, the mounting base plate 1 can move up and down along the guide member 61 under the drive of the nut.

[0051] In one embodiment, multiple pallet support devices are provided in the mounting frame 6, and at least two pallet support devices are symmetrically distributed about the central axis of the mounting frame 6.

[0052] Specifically, in combination Figure 4 To explain in more detail, two pallet support devices are arranged facing each other in the mounting frame 6. In this way, the two pallet support devices are symmetrically distributed about the central axis of the mounting frame 6. Moreover, when the pallet support plates 5 of the two pallet support devices are rotated to the support angle state, they can be located on the same horizontal plane and simultaneously support the bottom of the pallet, further ensuring the stability of the pallet support.

[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means two or more, unless otherwise explicitly specified.

[0054] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
