Description

Technical Field

[0002] In goods storage equipment with front and rear shelves, pallet moving devices often use electromagnets for attraction and gripping to pick up and place goods. When it is necessary to move goods from the front shelf to the rear shelf, or from the rear shelf to the front shelf, a rotating mechanism is required to drive the pallet moving device holding the goods to turn 180°. However, the rotating mechanism not only occupies a lot of space, but also, during the rotation process, the pallet moving device or the goods may interfere with the shelves and other goods on the shelves, resulting in damage to the goods or even the shelves. Summary of the Invention

Detailed Implementation

[0049] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0050] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0052] Please refer to the pallet moving device 10 in this embodiment of the application. Figure 13 This device can be used to move the tray 20 on the back-end storage rack 32 to the front-end storage rack 31, and also to move the tray 20 on the front-end storage rack 31 to the back-end storage rack 32. Please refer to [reference needed]. Figure 1 The pallet 20, which can be used to load goods, includes a body 21, a first hooked member 22, and a second hooked member 23. The first hooked member 22 is fixed to the front end of the body 21, and the second hooked member 23 is fixed to the rear end of the body 21. For example, the first hooked member 22 and the second hooked member 23 can be arranged symmetrically.

[0053] Please refer to section 2. Figure 12 The pallet moving device 10 in this embodiment includes a base 11, a fixed support mechanism 12, a hooking mechanism 13, and a lifting support mechanism 14. The fixed support mechanism 12 is disposed on the base 11 and supports the pallet 20. The hooking mechanism 13 is movably connected to the base 11 and has a vertically extending hook member that can be vertically inserted into a first hooked member 22 or a second hooked member 23. The lifting support mechanism 14 is disposed on the base 11.

[0054] When it is necessary to move the tray 20 on the rear storage rack 32 to the front storage rack 31, the hooking mechanism 13 is used to drag the tray 20 from the rear storage rack 32 to the fixed support mechanism 12 when the hook is inserted into the first hooked item 22. The lifting support mechanism 14 is used to drive the tray 20 supported on the fixed support mechanism 12 to move upward relative to the fixed support mechanism 12 and the base 11 to a first position, so that the hook is disengaged from the first hooked item 22. The gap between the tray 20 in the first position and the base 11 is configured as a first movement channel, so that the hooking mechanism 13 can move backward within the first movement channel until the hook is aligned with the second hooked item 23. The lifting support mechanism 14 is also used to drive the tray 20 in the first position to move downward relative to the base 11 to be supported on the fixed support member 121, so that the hook is inserted into the second hooked item 23. The hooking mechanism 13 is also used to push the tray 20 from the fixed support mechanism 12 to the front storage rack 31 when the hooking member is inserted into the second hooked member 23, so as to complete the movement of the tray 20 on the rear storage rack 32 to the front storage rack 31.

[0055] Similarly, in cases where it is necessary to move the tray 20 on the front storage rack 31 to the back storage rack 32, such as Figure 9 As shown, the hooking mechanism 13 is used to drag the tray 20 from the front storage rack 31 to the fixed support mechanism 12 when the hooking member is inserted into the second hooked member 23, as... Figure 10 As shown. The lifting support mechanism 14 is used to drive the tray 20 supported on the fixed support mechanism 12 to move upward relative to the fixed support mechanism 12 and the base 11 to a first position, so that the hook disengages from the second hooked member 23, as shown. Figure 11 As shown. The gap between the tray 20 in the first position and the base 11 is configured as a first moving channel, allowing the hooking mechanism 13 to move forward within the first moving channel until the hook is aligned with the first hooked member 22, as shown. Figure 12 As shown. The lifting support mechanism 14 is also used to drive the tray 20 in the first position to move downward relative to the base 11 and be supported on the fixed support member 121, so that the hook member is inserted into the first hooked member 22. The hooking mechanism 13 is also used to push the tray 20 from the fixed support mechanism 12 to the rear storage rack 32 when the hook member is inserted into the first hooked member 22, thus completing the movement of the tray 20 on the front storage rack 31 to the rear storage rack 32.

[0056] It is understood that in this embodiment, moving the tray 20 from one storage shelf to another operates on the same principle. Therefore, the descriptions of directions in this embodiment are for the purpose of facilitating understanding of the technical solution and should not be construed as limiting the embodiments of this application.

[0057] In this embodiment, the hooking mechanism 13 can move back and forth to move the pallet 20 onto the rear storage rack 32, the fixed support mechanism 12, or the front storage rack 31. For example, the pallet 20 can be moved from one storage rack to the fixed support mechanism 12, and then from the fixed support mechanism 12 to another storage rack. Simultaneously, when the pallet 20 is on the fixed support mechanism 12, the lifting support mechanism 14 can lift the pallet 20 upwards to provide a first moving channel for the hooking mechanism 13 to move back and forth, thus avoiding interference with the movement of the hooking mechanism 13. Therefore, in this embodiment, the hooking mechanism 13 has a short stroke, effectively improving the efficiency of picking up and placing goods. Compared with the prior art, the pallet moving device 10 does not need to rotate 180° during operation, avoiding interference between the pallet moving device 10 and the goods on the storage rack. This not only ensures high reliability and avoids damage to the goods, but also occupies less space, which is more conducive to equipment miniaturization.

[0058] In some implementation methods, please refer to Figures 3 to 5 as well as Figure 7The lifting support mechanism 14 includes a lifting guide 141, a lifting support 142, and a first drive 143. The lifting guide 141 is vertically inserted through the base 11, the lifting support 142 is fixed to the upper end of the lifting guide 141, and the first drive 143 is fixed to the lower end of the base 11. The first drive 143 can be used to drive the lifting guide 141 upward, thereby lifting the pallet 20 to a first position using the lifting support 142. The first drive 143 can also be used to drive the lifting guide 141 downward, thereby supporting the pallet 20 on the fixed support mechanism 12.

[0059] In this embodiment, the pallet 20 is driven to rise by the first driving member 143, so that a first moving channel can be formed between the pallet 20 and the base 11, thereby avoiding the pallet 20 moving to the pallet moving device 10 from interfering with the forward and backward movement of the hooking mechanism 13. The structure is simple and further reduces the space occupied by the pallet moving device 10 in the forward and backward direction, which is more conducive to the miniaturization of the equipment.

[0060] In some implementation methods, please refer to Figures 3 to 5 as well as Figure 7 The lifting support mechanism 14 also includes a transmission screw 144, a first sliding connector 145, and a second sliding connector 146. The transmission screw 144 is located at the output end of the first drive member 143 and extends horizontally. The first sliding connector 145 is drively connected to the transmission screw 144 and also slidably connected to the base 11. A guide groove 1451 is provided on the first sliding connector 145, which extends upward at an angle. The projection of the guide groove 1451 on the horizontal plane is parallel to the projection of the transmission screw 144 on the horizontal plane. The second sliding connector 146 is correspondingly and fixed to the lifting support member 142. The second sliding connector 146 is located below the corresponding lifting support member 142 and fixed to the lower end of the lifting guide member 141. The second sliding connector 146 is slidably connected to the guide groove 1451. The first driving member 143 is used to drive the transmission screw member 144 to rotate around the axis of the transmission screw member 144. When the transmission screw member 144 rotates around its own axis, the first sliding connecting member 145 moves along the extension direction of the transmission screw member 144 under the action of the screw member, thereby causing the fixedly connected second sliding connecting member 146, lifting guide member 141 and lifting support member 142 to move up and down together.

[0061] In this embodiment, when the first driving member 143 drives the first sliding connector 145 to move in the horizontal direction, the second sliding connector 146 can move vertically under the action of the first sliding connector 145. Compared with the first driving member 143 directly driving the second sliding connector 146 to move in the vertical direction, this embodiment can reduce the space occupied by the pallet moving device 10 in the vertical direction, which is more conducive to the miniaturization of the equipment.

[0062] In some implementation methods, please refer to Figure 4 , Figure 7 and Figure 8 The second sliding connector 146 may include a first connecting portion 1461 and a sliding portion 1462 protruding from the first connecting portion 1461. The first connecting portion 1461 is fixed to the lower end of the lifting guide 141, and the sliding portion 1462 is slidably connected within the guide groove 1451. As an example, the sliding portion 1462 is a roller that can rotate around its own axis. When the first sliding connector 145 and the second sliding connector 146 move relative to each other, the sliding portion 1462 can roll within the guide groove 1451, thereby reducing wear, improving the movement accuracy of the pallet moving device 10, and extending the service life of the pallet moving device 10.

[0063] In some implementation methods, please refer to Figure 7 The transmission screw 144 can extend in the front-to-back direction, meaning its extension direction is parallel to the moving direction of the hooking mechanism 13. Therefore, providing the transmission screw 144 does not increase the space occupied by the pallet moving device 10 in the front-to-back direction, nor does it increase the space occupied by the pallet moving device 10 in other directions on the horizontal plane, which is more conducive to equipment miniaturization. It should be noted that in other embodiments, the transmission screw 144 can also extend in other directions on the horizontal plane, which can be set according to actual conditions, and will not be elaborated here.

[0064] In some implementation methods, please refer to Figure 7 The first driving component 143 can be a motor, and the transmission screw component 144 is coaxially fixed to the output shaft of the motor.

[0065] It is understood that in other embodiments, the first driving member 143 may also be other driving mechanisms, and the first driving member 143 may also directly drive the first sliding connector 145 to slide in the horizontal direction. For example, the first driving member 143 may be a cylinder, and the first sliding connector 145 may be fixed to the piston rod of the cylinder. The extension and retraction of the piston rod causes the first sliding connector 145 to move in the horizontal direction.

[0066] In some implementation methods, please refer to Figure 4The lifting support mechanism 14 includes two lifting support members 142, which are symmetrically arranged on both sides of the fixed support mechanism 12. Each lifting support member 142 is connected to at least one lifting guide member 141. The first driving member 143 is used to drive all the lifting guide members 141 at the same time, so that the two lifting support members 142 lift and lower synchronously, which improves the stability of the lifting movement of the pallet 20, prevents the pallet 20 from slipping, and further avoids damage to the goods.

[0067] In some implementation methods, please refer to Figures 3 to 5 Each lifting support 142 can have two lifting guides 141 symmetrically fixed at its lower end, so that the lifting support 142 can be lifted and lowered more stably.

[0068] As an example, please refer to Figure 7 The first connecting part 1461 can be a long strip structure extending parallel to the transmission lead screw 144. Two lifting guides 141 are respectively arranged near the two ends of the first connecting part 1461, and the sliding part 1462 is connected to the middle of the first connecting part 1461. In order to further improve the stability of the lifting movement of the pallet 20 and extend the service life of the pallet moving device 10, the base 11 can be fixed with a first linear bearing 19 corresponding to the lifting guide 141, and the lifting guide 141 is slidably connected in the corresponding first linear bearing 19. The first sliding connector 145 may include a second connecting portion 1452, a third connecting portion 1453, and two fourth connecting portions 1454. The second connecting portion 1452 extends in a left-right direction. The third connecting portion 1453 extends horizontally and is fixed to one side of the upper end of the second connecting portion 1452. The two fourth connecting portions 1454 are symmetrically fixed to the left and right sides of the second connecting portion 1452, and are also respectively fixed to the third connecting portion 1453, thereby enhancing the stability of the first sliding connector 145 and improving the stability of the lifting movement of the tray 20. Each of the two fourth connecting portions 1454 has a guide groove 1451, and the guide grooves 1451 on the two fourth connecting portions 1454 are symmetrically arranged. The lower end of the base 11 is also provided with a first guide rail 15 parallel to the transmission lead screw 144, and the upper end of the fourth connecting part 1454 is fixed with a first slider 16 that slides with the first guide rail 15, so that the first sliding connector 145 can slide stably relative to the base 11.

[0069] In some implementation methods, please refer to Figure 2 , Figure 4 and Figure 6The lifting support 142 may include a first support portion 1421 and two first limiting portions 1422. The first support portion 1421 extends in the front-back direction, and the two first limiting portions 1422 are respectively fixed to the front and rear ends of the first support portion 1421. When the lifting support 142 moves upward to abut against the tray 20, the tray 20 is supported on the first support portion 1421, and the two first limiting portions 1422 block the front and rear sides of the tray 20, thereby preventing the tray 20 from moving or falling during the lifting process. It can also correct the position of the tray 20 in the front-back direction so that the subsequent hook can be inserted more accurately into the hooked part of the tray 20.

[0070] As an example, please refer to Figure 2 In order to enable the pallet 20 to fall quickly and effectively onto the first support part 1421, a first guide surface 14221 is formed on one side of the two first limiting parts 1422 facing each other. Even if the position of the pallet 20 supported on the fixed support member 121 is deviated in the front-back direction, the pallet 20 can slide down onto the first support part 1421 along the first guide surface 14221.

[0071] In some implementation methods, please refer to Figure 2 The lifting support mechanism 14 also includes two first limiting members 147, which are respectively fixed to opposite sides of the two lifting support members 142. When the hooking mechanism 13 drags the tray 20 from the front storage rack 31 or the rear storage rack 32 onto the fixed support member 121, the two first limiting members 147 can guide the tray 20, allowing it to be smoothly dragged onto the fixed support member 121 and preventing it from shifting. After the tray 20 is dragged onto the tray moving device 10, the two first limiting members 147 cooperate to restrict the tray 20 supported on the fixed support mechanism 12 or the lifting support mechanism 14 between the two first limiting members 147, further preventing the tray 20 from falling and correcting its position in the left and right directions, making it easier for the hooking mechanism 13 to push the tray 20 into the front storage rack 31 or the rear storage rack 32.

[0072] In some implementation methods, please refer to Figure 2The first limiting member 147 includes a second limiting part 1471 and a third limiting part 1472. The second limiting part 1471 is fixed to the lifting support member 142 and extends in the front-rear direction, while the third limiting part 1472 is fixed to the upper end of the second limiting part 1471 and extends in the front-rear direction. Correspondingly, the pallet 20 may also include a fourth limiting part 24 symmetrically arranged on the left and right sides of the body 21. When the pallet 20 is dragged to the pallet moving device 10, the fourth limiting part 24 is restricted below the third limiting part 1472, thereby preventing the pallet 20 from moving upward relative to the pallet moving device 10 and disengaging from it during the movement, thus improving the reliability of the pallet moving device 10.

[0073] As an example, please refer to Figures 2 to 4 ,as well as Figure 7 and Figure 8 In order to avoid interfering with the pallet 20 and to drag the pallet 20 onto the pallet moving device 10 more quickly and accurately, the front and rear ends of the second limiting part 1471 of the two first limiting members 147 can also form a second guide surface 14711 extending in opposite directions at the front and rear ends, and the front and rear ends of the third limiting part 1472 of the two first limiting members 147 can also form a third guide surface 14721 extending upward at the tilt.

[0074] In some implementation methods, please refer to Figure 6 The fixed support mechanism 12 includes two fixed support members 121, and the hooking mechanism 13 is disposed between the two fixed support members 121. The two fixed support members 121 are spaced apart and parallel to each other, and the two fixed support members 121 extend forward and backward respectively, so as to support the tray 20 more stably.

[0075] As an example, please refer to Figure 2 In order to avoid interfering with the pallet 20 and to drag the pallet 20 onto the pallet moving device 10 more quickly, the front and rear ends of the fixed support member 121 can also form a fourth guide surface 1211 with an inclined extension.

[0076] In some implementation methods, please refer to Figure 2 , Figure 4 and Figure 6 The hooking mechanism 13 includes a third sliding connector 131 and two hooking members. The third sliding connector 131 is movably connected to the base 11, and the two hooking members are a first hooking member 132 and a second hooking member 133. The first hooking member 132 is located at the rear end of the third sliding connector 131 and engages with a first hooked member 22. The second hooking member 133 is located at the front end of the third sliding connector 131 and engages with a second hooked member 23.

[0077] In some implementation methods, please refer to Figure 6 and Figure 8 The upper end of the base 11 can also be fixed with a second guide rail 17 extending in the front-back direction, and the lower end of the third sliding connector 131 can also be fixed with a second slider 18 that slides with the second guide rail 17, thereby more effectively limiting the movement path of the hooking mechanism 13.

[0078] In some embodiments, the pallet moving device 10 may further include a second driving member (not shown) that drives the hooking mechanism 13 to move back and forth. As an example, the second driving member may be a belt mechanism, a cylinder, or other driving mechanism, which can be set according to the actual situation, and will not be described in detail here.

[0079] In some implementation methods, please refer to Figure 4 The hooking mechanism 13 further includes a floating guide 134, a first elastic element 135, and a second elastic element 136. The floating guide 134 passes through the third sliding connector 131, with one end fixed to the first hook 132 and the other end fixed to the second hook 133. The first elastic element 135 and the second elastic element 136 are respectively sleeved on the floating guide 134. One end of the first elastic element 135 abuts against the first hook 132, and the other end abuts against the third sliding connector 131; that is, the first elastic element 135 is compressed between the first hook 132 and the third sliding connector 131. One end of the second elastic element 136 abuts against the second hook 133, and the other end abuts against the third sliding connector 131; that is, the second elastic element 136 is compressed between the second hook 133 and the third sliding connector 131.

[0080] In some implementation methods, please refer to Figure 4 A second linear bearing 137 can also be fixed on the third sliding connector 131. The floating guide 134 is slidably connected to the second linear bearing 137, thereby avoiding friction between the third sliding connector 131 and the floating guide 134, improving the motion accuracy of the hooking mechanism 13, and extending the service life of the pallet moving device 10.

[0081] In this embodiment, compression buffering is performed using the first elastic element 135 or the second elastic element 136 to eliminate precise positioning errors, thereby enabling the first hooking element 132 and the second hooking element 133 to be inserted into the corresponding hooked element.

[0082] In some implementation methods, please refer to Figure 2 , Figure 4 and Figure 6The hooking mechanism 13 also includes a second limiting member 138 fixed to the third sliding connector 131. The second limiting member 138 is disposed between the first hooking member 132 and the second hooking member 133. The second limiting member 138 can be used to limit the first hooking member 132 to move forward to a first extreme position relative to the third sliding connector 131. The second limiting member 138 can also be used to limit the second hooking member 133 to move backward to a second extreme position relative to the third sliding connector 131.

[0083] As an example, the first elastic element 135 can be a spring, and the second elastic element 136 can be a spring.

[0084] In some implementation methods, please refer to Figure 4 and Figure 6 The hooking mechanism 13 includes two parallel and spaced floating guide members 134. The two floating guide members 134 are slidably connected to the corresponding second linear bearings 137. The two floating guide members 134 are fixed between the first hook member 132 and the second hook member 133. Each floating guide member 134 is fitted with a first elastic member 135 and a second elastic member 136. The second limiting member 138 is located between the two floating guide members 134, so that the first hook member 132 and the second hook member 133 are subjected to more uniform force and can hook the tray 20 more stably.

[0085] Please refer to Figure 13 The goods storage device in this application embodiment includes a pallet 20, a shelf assembly 30, a motion device 40, and a pallet moving device 10 provided in any of the above embodiments. The shelf assembly 30 includes a front storage rack 31 and a rear storage rack 32 for placing the pallet 20. The front storage rack 31 and the rear storage rack 32 are spaced apart, and the gap between them is configured as a second moving channel 33. The motion device 40 is connected to the base 11 and is used to drive the pallet moving device 10 to move within the second moving channel 33.

[0086] In this embodiment, the hooking mechanism 13 can move back and forth to move the pallet 20 onto the rear storage rack 32, the fixed support mechanism 12, or the front storage rack 31. The lifting support mechanism 14 can lift the pallet 20 upwards to provide a first moving channel for the hooking mechanism 13 to move back and forth, thus avoiding interference with the movement of the hooking mechanism 13. In this embodiment, the hooking mechanism 13 has a short stroke, which can effectively improve the efficiency of picking up and placing goods. During operation, the pallet moving device 10 does not need to rotate 180°, which can avoid interference between the pallet moving device 10 and the goods on the storage rack. This not only ensures high reliability and avoids damage to the goods, but also occupies little space, which is more conducive to the miniaturization of the equipment.

[0087] As an example, the front storage rack 31 and the rear storage rack 32 are each provided with multiple storage compartments for storing goods. Pallets 20 loaded with goods or pallets 20 without goods can be stored in the storage compartments.

[0088] In some embodiments, the motion device 40 can drive the tray moving device 10 to move back and forth, up and down, and / or left and right.

[0089] As an example, the working principle of the goods storage device is as follows: When it is necessary to move the pallet 20 on the rear storage rack 32 to the front storage rack 31, the motion device 40 drives the pallet moving device 10 to move as a whole to the first target storage cell of the rear storage rack 32. The hooking mechanism 13 moves backward until the first hooking member 132 is aligned with the first hooked item 22. The motion device 40 drives the pallet moving device 10 to move upward as a whole until the first hooking member 132 is inserted into the first hooked item 22. Then, the second driving member drives the hooking mechanism 13 to drag the pallet 20 from the rear storage rack 32 to the fixed support mechanism 12. Then, after the motion device 40 drives the pallet moving device 10 to move as a whole to the second target storage cell of the front storage rack 31, or during this movement, the lifting support mechanism 14 drives the pallet 20 supported on the fixed support mechanism 12 to move upward relative to the fixed support mechanism 12 and the base 11 to the first position, thereby causing the first hooking member 132 to disengage from the first hooked item 22. After the first hooking member 132 disengages from the first hooked member 22, the second driving member drives the hooking mechanism 13 to move backward within the first moving channel until the second hooking member 133 aligns with the second hooked member 23. The lifting support mechanism 14 drives the tray 20 in the first position to move downward relative to the base 11 until it is supported on the fixed support member 121, so that the second hooking member 133 is inserted into the second hooked member 23. When the motion device 40 drives the tray moving device 10 to move as a whole to the second target storage compartment of the front storage rack 31, the second driving member drives the hooking mechanism 13 to push the tray 20 from the fixed support mechanism 12 to the front storage rack 31. Then the motion device 40 drives the tray moving device 10 to move downward as a whole, so that the second hooking member 133 separates from the second hooked member 23, and the movement of the tray 20 is completed.

[0090] When it is necessary to move the tray 20 on the front storage rack 31 to the rear storage rack 32, the motion device 40 drives the tray moving device 10 to move as a whole to the third target storage cell of the front storage rack 31. The hooking mechanism 13 moves forward until the second hooking member 133 is aligned with the second hooked member 23. The motion device 40 drives the tray moving device 10 to move upward as a whole until the second hooking member 133 is inserted into the second hooked member 23. Figure 9As shown. The second driving component drives the hooking mechanism 13 to drag the tray 20 from the front storage rack 31 to the fixed support mechanism 12, as shown. Figure 10 As shown. Then, the motion device 40 drives the tray moving device 10 to move as a whole to the fourth target storage compartment of the rear storage rack 32, or during this movement, the lifting support mechanism 14 drives the tray 20 supported on the fixed support mechanism 12 to move upward relative to the fixed support mechanism 12 and the base 11 to the first position, thereby causing the second hook 133 to disengage from the second hooked member 23, as shown. Figure 11 As shown. After the second hooking member 133 disengages from the second hooked member 23, the second driving member drives the hooking mechanism 13 to move forward within the first moving channel until the first hooking member 132 is aligned with the first hooked member 22, as shown. Figure 12 As shown. The lifting support mechanism 14 drives the tray 20, which is in the first position, to move downward relative to the base 11 until it is supported on the fixed support member 121, so that the first hook member 132 is inserted into the first hooked member 22. When the motion device 40 drives the tray moving device 10 to move as a whole to the fourth target storage compartment of the rear storage rack 32, the second drive member drives the hooking mechanism 13 to push the tray 20 from the fixed support mechanism 12 to the rear storage rack 32. Then the motion device 40 drives the tray moving device 10 to move downward as a whole, so that the first hook member 132 separates from the first hooked member 22, and the movement of the tray 20 is completed.
