In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0032] Combine the following Figures 1 to 5 The utility model is described in detail.

[0033] See also Figure 1 and Figure 2 As shown, the pallet dispensing device provided by the embodiment of the utility model includes: a frame 10, a lifting and clamping unit 20 and a conveying mechanism 30. A placement space for placing wooden pallets is formed in the frame 10. The loading end of the conveying mechanism 30 is located below the placement space. The lifting and clamping unit 20 includes a lifting mechanism 210 and a clamping mechanism 220.

[0034] The lifting mechanism 210 includes a lifting bracket 211 and a first driving assembly 212 . The first driving assembly 212 is disposed on the frame 10 . The first driving assembly 212 is connected to the lifting bracket 211 in a transmission manner to drive the lifting bracket 211 to move vertically.

[0035] The clamping mechanism 220 includes two clamping members 221 and a second driving assembly 222. The two clamping members 221 are symmetrically arranged on both sides of the lifting bracket 211. The two clamping members 221 are both rotatably connected to the lifting bracket 211. The second driving assembly 222 is arranged on the lifting bracket 211. The second driving assembly 222 is transmission-connected to the clamping members 221 to drive the clamping parts of the two clamping members 221 to approach or move away from each other. The clamping parts of the two clamping members 221 are both located in the placement space.

[0036] The pallet distribution device provided by the utility model is provided with a frame 10, a lifting clamping unit 20 and a conveying mechanism 30. When distributing wooden pallets, the stacked wooden pallets are placed in the placement space of the frame 10 and carried by the conveying mechanism 30. According to the number of wooden pallets distributed each time, the lifting clamping unit 20 is driven to clamp the stacked wooden pallets and move them vertically upward. The number of wooden pallets stranded on the conveying mechanism 30 corresponds to the number distributed each time. The conveying mechanism 30 transports the wooden pallets remaining thereon to a designated position, and then drives the lifting clamping unit 20 to place the remaining stacked wooden pallets on the conveying mechanism 30. The above distribution steps are repeated until all wooden pallets are distributed. The pallet distribution device provided by the utility model can adapt to the distribution operation of wooden pallets of different specifications, will not cause material jamming, and can realize the rapid distribution of wooden pallets, greatly improving work efficiency.

[0037] In addition, the number of wooden pallets delivered each time can be controlled by controlling the clamping height of the lifting clamping unit 20. For example, when the number of wooden pallets delivered is set to one, the lifting bracket 211 can be set to rise to a first height, clamp and lift the stacked wooden pallets, and retain one wooden pallet on the conveying mechanism 30. When the number of wooden pallets delivered is set to two, the lifting bracket 211 can be set to rise to a second height, clamp and lift the stacked wooden pallets, and retain two wooden pallets on the conveying mechanism 30. The remaining numbers of wooden pallets delivered can be deduced in the same way, and will not be repeated.

[0038] Specifically, see Figure 3 As shown, the clamping member 221 is a plate-shaped member, and a clamping portion (claw) is provided at the front end of the clamping member 221. During the clamping operation, the clamping portions of the two clamping members 221 are driven to approach each other by the second driving assembly 222, and the clamping portions of the two clamping members 221 can extend into the gap of the wooden pallet to clamp it. The second driving assembly 222 drives the clamping portions of the two clamping members 221 to move away from each other, and the clamping portions of the two clamping members 221 can move out of the gap of the wooden pallet to cancel the clamping of the wooden pallet.

[0039] One side of the frame 10 is provided with an opening, so that external equipment (such as a forklift, etc.) can place the pre-stacked wooden pallets into the placement space through the opening.

[0040] The conveying mechanism 30 is a conveying roller, and the wooden pallet can be driven to move along a set path by driving the conveying roller to rotate.

[0041] The first driving assembly 212 can drive the lifting bracket 211 to move vertically up and down, which can be implemented in the following multiple ways.

[0042] In some embodiments, the first drive assembly 212 may be a linear motor drive assembly, which drives the lifting bracket 211 to move vertically through electromagnetic force. The linear motor can realize the vertical lifting function according to different structural forms (such as linear motors, linear electromagnetic drives, etc.). It can accurately control the displacement of the lifting bracket 211, thereby accurately controlling the clamping height of the clamping mechanism 220 to meet the current demand for the delivery amount of the wooden pallet. In specific implementation, the lifting bracket 211 can be connected to the output end of the linear motor drive assembly.

[0043] In some embodiments, the first drive assembly 212 may be a hydraulic drive assembly, which may use liquid pressure to drive a piston to push the lifting bracket 211 to perform lifting motion. The hydraulic drive assembly has a large load-bearing capacity and can adapt to the distribution of large quantities of wooden pallets. In specific implementation, the lifting bracket 211 may be connected to the hydraulic rod of the hydraulic drive assembly.

[0044] In some embodiments, the first drive assembly 212 may be an electric screw assembly, which drives the screw to rotate by a motor, and the lifting bracket 211 and the screw are configured to be threadedly connected, so that the rotational motion of the screw can be converted into the vertical linear motion of the lifting bracket 211. The electric screw assembly has a self-locking function, and after the lifting bracket 211 (and the stacked wooden pallets) are lifted to a set height, they can be stably maintained at the current height.

[0045] Since one end of the two clamping members 221 is rotatably connected to the lifting bracket 211, the second driving assembly 222 can drive the clamping members 221 to rotate around the rotation connection point between the clamping members 221 and the lifting bracket 211. The second driving assembly 222 can be implemented in the following ways.

[0046] In some embodiments, the second driving component 222 may be a linear driving component, such as a hydraulic driving component (hydraulic cylinder), an electric driving component (electric cylinder) or a pneumatic driving component (pneumatic cylinder), etc. In specific implementation, it is only necessary to fix the linear driving component at a set position, connect its output end to the appropriate position of the clamping member 221, and drive the output end of the linear driving component to move telescopically, so as to drive the clamping member 221 to rotate around the rotation connection point between the clamping member 221 and the lifting bracket 211, so that the two clamping members 221 complete the clamping and releasing actions.

[0047] Of course, the first driving assembly 212 and the second driving assembly 222 may also be other mechanisms in the prior art that can realize corresponding driving actions, which will not be described in detail.

[0048] See also Figure 1 and Figure 2As shown, according to a preferred embodiment of the utility model, the first driving assembly 212 includes a driving motor 2121, a lead screw 2122 and a threaded seat 2123. The driving motor 2121 is arranged on the frame 10, and the output end of the driving motor 2121 is transmission-connected with the lead screw 2122. The threaded seat 2123 is arranged on the lifting bracket 211, and the threaded seat 2123 is threadedly matched with the lead screw 2122. The lead screw 2122 and the threaded seat 2123 can be used to accurately control the distance of the lifting bracket 211 rising or moving down, and the driving motor 2121 can be a servo motor. The lead screw 2122 and the threaded seat 2123 have a self-locking function, and after the lifting bracket 211 (and the stacked wooden pallets) are lifted to a set height, they can be stably maintained at the current height.

[0049] Specifically, when the lifting bracket 211 needs to be driven to move upward, the output shaft of the driving motor 2121 can be controlled to rotate along the first rotation direction, and the output shaft of the driving motor 2121 drives the lead screw 2122 to rotate. Since the lead screw 2122 is threadedly matched with the threaded seat 2123, the rotational movement of the lead screw 2122 can be converted into a linear movement of the threaded seat 2123, thereby driving the lifting bracket 211 to move upward. Correspondingly, when the lifting bracket 211 needs to be driven to move downward, it is only necessary to control the output shaft of the driving motor 2121 to rotate along the second rotation direction, which is opposite to the first rotation direction.

[0050] Preferably, the threaded seat 2123 in this embodiment is integrally provided with the lifting bracket 211 .

[0051] Further, according to some embodiments of the utility model, the first drive assembly 212 further includes a worm wheel 2124 and a worm 2125, the worm wheel 2124 is connected to the output shaft of the drive motor 2121, the worm 2125 is connected to the lead screw 2122, the worm wheel 2124 and the worm 2125 cooperate, and the angle between the output shaft of the drive motor 2121 and the lead screw 2122 is 90°. By providing a worm wheel and worm structure, the output shaft of the drive motor 2121 and the lead screw 2122 can be configured to be perpendicular to each other, which is convenient for arranging the drive motor 2121.

[0052] Specifically, in this embodiment, by providing a worm gear structure, the output shaft of the drive motor 2121 and the lead screw 2122 are configured to be perpendicular to each other, so that the drive motor 2121 can be disposed on the back of the frame 10.

[0053] See also Figure 1 and Figure 2As shown, according to a preferred embodiment of the utility model, the second drive assembly 222 includes two linear drive devices 2221, both of which are arranged on the lifting bracket 211, and the output ends of the linear drive devices 2221 are connected to the clamping member 221 in a one-to-one correspondence. The linear drive device 2221 can be a hydraulic driving device (hydraulic cylinder), an electric driving device (electric cylinder) or a pneumatic driving device (cylinder), etc. The above-mentioned linear drive device 2221 has a simple structure, is easy to install and arrange, and has a fast response speed, which can significantly improve the efficiency of the distribution operation of the wooden pallet.

[0054] During specific implementation, it is only necessary to fix the linear drive device 2221 at a set position and connect its output end to the appropriate position of the clamping member 221. The output end of the linear drive assembly is driven to telescopically move, thereby driving the clamping member 221 to rotate around its rotation connection point with the lifting bracket 211, so that the two clamping members 221 can complete the clamping and releasing actions.

[0055] In this embodiment, the linear drive device 2221 is a pneumatic driving device (cylinder). A fixed seat is provided in the middle of the lifting bracket 211. The cylinder includes a cylinder body and a telescopic rod. The end of the cylinder body is hinged to the fixed seat. The telescopic rod is telescopically arranged on the cylinder body. The end of the telescopic rod is hinged to the clamping member 221. By hingedly connecting the end of the cylinder body to the fixed seat and the end of the telescopic rod to the clamping member 221, when the cylinder drives the clamping member 221 to rotate, the cylinder body and the telescopic rod can adaptively adjust their positions and angles to prevent jamming.

[0056] See also Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the pallet dispensing device includes two lifting and clamping units 20, and the two lifting and clamping units 20 are symmetrically arranged on both sides of the frame 10. By symmetrically arranging the lifting and clamping units 20 on both sides of the frame 10, the two lifting and clamping units 20 can synchronously clamp the wooden pallet and drive the wooden pallet to move up and down, which can greatly increase the load capacity of the wooden pallet, and can ensure the stability of the clamped wooden pallet when it moves up and down, and prevent the stacked wooden pallets from tilting or even collapsing.

[0057] According to some embodiments of the present invention, the pallet distribution device further includes a pallet detection device (not shown in the figure) for detecting the wooden pallet, and the pallet detection device is arranged on the side of the conveying mechanism 30. By arranging the pallet detection device on the side of the conveying mechanism 30, it is possible to detect whether there is a pallet at the set position of the conveying mechanism 30, indicating whether the wooden pallet has been distributed in place.

[0058] Specifically, the tray dispensing device may be a sensor with object detection capability, such as a photoelectric sensor, an ultrasonic sensor or an infrared sensor.

[0059] Among them, the photoelectric sensor detects the wooden pallet on the conveying mechanism 30 by means of the mutual emission of the transmitter and the receiver. When the wooden pallet blocks the light beam, the sensor outputs a signal, indicating that there is a wooden pallet at the set position of the conveying mechanism 30. The ultrasonic sensor can emit ultrasonic pulses and receive the reflected signals. When the wooden pallet approaches the sensor, the ultrasonic reflected signal will change, and the sensor can detect the presence of the wooden pallet at the set position of the conveying mechanism 30. The infrared sensor can detect the obstruction or reflection of infrared light by the wooden pallet. When the wooden pallet passes through the sensor area, the change of the infrared light signal can be captured by the sensor, thereby judging that there is a wooden pallet at the set position of the conveying mechanism 30.

[0060] According to some embodiments of the present invention, the pallet distribution device further includes a control unit 40, and the pallet detection device, the first drive assembly 212, and the second drive assembly 222 are all in communication connection with the control unit 40. By setting the control unit 40, when the pallet detection device detects that the wooden pallet is delivered to the set position, the control unit 40 can be used to issue a control instruction to the first drive assembly 212 and the second drive assembly 222 to perform the next distribution operation.

[0061] For example, when the pallet detection device detects that the wooden pallet has reached a set position (such as the unloading end of the conveying mechanism 30), the control unit 40 can control the first drive component 212 to lower the remaining wooden pallets onto the conveying mechanism 30, control the first drive component 212 to release the two clamps 221, and perform the next wooden pallet distribution operation.

[0062] Specifically, the control unit 40 includes a control cabinet, in which a PLC control component is built. The control cabinet is installed on a side wall of the frame 10 .

[0063] See also Figure 4 and Figure 5 As shown, according to some embodiments of the present invention, a rotating connection seat 230 is respectively provided on both sides of the bottom of the lifting bracket 211, and the rotating connection seat 230 corresponds to the clamping member 221 one by one. The rotating connection seat 230 includes a housing 231 and a plurality of bearings 232, and the plurality of bearings 232 are arranged in the housing 231 at intervals along the vertical direction. A rotating shaft 233 is vertically provided at the end of the clamping member 221, and the inner ring of the bearing 232 is sleeved on the rotating shaft 233. By providing the rotating connection seat 230, the clamping member 221 and the lifting bracket 211 can be configured as a relatively stable rotating connection structure.

[0064] See also Figure 5As shown, specifically, in this embodiment, two bearings 232 are provided in the housing 231 of each rotating connection seat 230, and the two bearings 232 are respectively provided at the upper and lower ends of the housing 231, and the outer ring of the bearing 232 is clamped in the bearing 232 groove of the housing 231, and the inner ring of the bearing 232 is sleeved on the rotating shaft 233. When the second driving component 222 applies a driving action to the clamping member 221, the clamping member 221 can rotate along a set direction under the cooperation of the rotating shaft 233 and the bearing 232.

[0065] See also Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the side wall of the frame 10 is provided with a mounting groove 110, and the lifting bracket 211 is located in the mounting groove 110. By providing the mounting groove 110 on the side wall of the frame 10, it is possible to provide an installation space for the lifting clamping unit 20, and it is possible to allow the lifting clamping unit 20 to move vertically within the mounting groove 110 by a set distance.

[0066] The following is an explanation of the working process of the tray distribution device provided by the utility model. Figures 1 to 5 shown.

[0067] Before the wooden pallets are distributed, a plurality of stacked wooden pallets are placed in the placement space by a forklift, and the wooden pallet at the bottom contacts the conveying mechanism 30 .

[0068] Take the example of one wooden pallet being delivered each time. During delivery, the first driving component 212 first drives the lifting bracket 211 to move upward, and drives the clamping mechanism 220 to move upward synchronously, so that the two clamping members 221 are located at the position of the second-to-last wooden pallet from bottom to top, and then the second driving component 222 drives the clamping parts of the two clamping members 221 to extend into the gap of the wooden pallet, and the first driving component 212 continues to drive the lifting bracket 211 to move upward for a certain distance, so that the wooden pallet at the bottom layer is completely detached from the wooden pallet above, and all the wooden pallets above are kept at the current height, and then the conveying mechanism 30 conveys the wooden pallet located thereon, and when the pallet detection device detects that the wooden pallet has reached the specified position, the conveying mechanism 30 stops running, and the first driving component 212 drives the lifting bracket 211 to move downward, placing all the stacked wooden pallets on the conveying mechanism 30, and then repeats the above operation steps until all wooden pallets are delivered.

[0069] During this process, the first driving component 212 controls the lifting bracket 211 to rise or move downward by steering the output shaft of the driving motor 2121, and the second driving component 222 controls the clamping parts of the clamping member 221 to move closer to or farther away from each other by telescoping the output ends of the two linear driving devices 2221.

[0070] It should be noted that the pallet distribution device provided by the present invention can distribute a single or multiple wooden pallets each time, and the number of wooden pallets distributed each time can be the same or different, thereby realizing flexible distribution of wooden pallets.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
