Description

Technical Field

[0001] The invention relates to the technical field of logistics, and in particular to a clamping type logistics layer rack shuttle vehicle. Background Art

[0002] The clamping type logistics shelf shuttle (hereinafter referred to as the shuttle) is a device that can move in an automated three-dimensional warehouse. When the shuttle moves to a preset position in the three-dimensional warehouse, the shuttle can drive the two relatively arranged arms on it to extend or retract synchronously, so as to push and remove items located on one side of the two sides of the shuttle through the abutment blocks on the arms. However, after investigating the existing shuttles, the inventor found that the existing shuttles have the following problems: 1. The shuttle needs to be provided with two driving parts to drive the two arms to move accordingly, and the provision of two driving parts will increase the production cost of the shuttle; 2. The movable extension amount of the arms is small, so it is difficult for the shuttle to remove items with longer specifications. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a clamping type logistics layer rack shuttle vehicle.

[0004] According to an embodiment of the present invention, a clamping type logistics shelf shuttle vehicle comprises a vehicle body, a linkage assembly, a transmission assembly and a second driving member, the vehicle body is provided with a storage plate and two mounting arms respectively located at the front and rear sides of the storage plate, the mounting arm is provided with an extension arm that can slide in the left and right directions, the extension arm is provided with an arm that can slide in the left and right directions, the extension arm and the arm are both located above the storage plate, and the left and right ends of the arm are provided with a first driving member, the first driving member can drive the abutment block thereon to rotate to an avoidance state or a pushing state, the linkage assembly is provided with two, one of the mounting arm, one of the extension arm and one of the arm that are slidably arranged in sequence are connected to one of the linkage assemblies, the transmission assembly is provided on the vehicle body, the two extension arms are connected to the transmission assembly, the second driving member is provided on the vehicle body, the second driving member is connected to the transmission assembly, and the second driving member can drive the two extension arms to move left or right synchronously through the transmission assembly, wherein the extension arm that moves left or right can drive the arm thereon to move left or right accordingly through the linkage assembly.

[0005] A clamping type logistics layer rack shuttle according to an embodiment of the present invention has at least the following beneficial effects:

[0006] When the shuttle moves to the preset position of the stereoscopic warehouse, the process of the shuttle removing the items on one side of the left and right sides of the shuttle is as follows (taking the removal of the left side items as an example, refer to Figure 1): 1. The two first driving members, both located at the left end, drive the two abutment blocks thereon to rotate to the avoidance state; 2. The second driving member drives the two extension arms to move leftward and outward synchronously through the transmission assembly. At this time, the two extension arms that move leftward and outward synchronously drive the two holding arms thereon to further move leftward and outward through the two linkage assemblies, so that the article is placed between the two holding arms, and the two abutment blocks that are both located at the left end and in the avoidance state are moved to the left side of the article; 3. The two first driving members, both located at the left end, drive the two abutment blocks thereon to rotate to the pushing state; 4. The second driving member drives the two extension arms to move rightward and retract synchronously through the transmission assembly. At this time, the two extension arms 400 that move rightward and retract synchronously drive the two holding arms thereon to further move rightward and retract through the two linkage assemblies, so that the two abutment blocks that are both located at the left end and in the pushing state push the article between the two holding arms, so that the article is moved to the storage plate.

[0007] When the shuttle moves to the preset position of the stereoscopic warehouse, the process of the shuttle moving the items on it to one of the left and right sides of the shuttle is as follows (taking the transfer of items to the left side of the shuttle as an example, refer to Figure 1 ): 1. The two first driving members, both located at the right end, drive the two abutment blocks thereon to rotate to the pushing state; 2. The second driving member drives the two extension arms to move leftward and outward synchronously through the transmission assembly. At this time, the two extension arms that move leftward and outward synchronously drive the two holding arms thereon to move leftward and outward further through the two linkage assemblies, so that the two abutment blocks, both located at the right end and in the pushing state, push the objects on the storage plate, so that the objects located between the two holding arms are moved to the left side of the shuttle.

[0008] Through the above structure, on the one hand, the second driving member can drive the two extension arms to move left or right synchronously through the transmission assembly, so as to synchronously drive the two holding arms to move left or right through the two linkage assemblies. In other words, the shuttle vehicle of the present application uses a driving member, a transmission assembly and a linkage assembly to make the two holding arms move synchronously. Therefore, compared with the traditional shuttle vehicle, the shuttle vehicle of the present application uses a small number of driving members to drive the two holding arms to move synchronously, so it can effectively reduce the production cost; on the other hand, the extended extension arm can drive the holding arm thereon to further move and extend through the corresponding linkage assembly. In other words, on the basis of moving and extending with the extension arm, the holding arm can still move and extend relative to the extension arm under the action of the linkage assembly. Therefore, compared with the traditional shuttle vehicle, the holding arm of the shuttle vehicle of the present application can move and extend a larger amount, so it can remove objects with longer specifications.

[0009] According to some embodiments of the present invention, the linkage assembly includes a runner and a linkage belt. There are two runners, which are rotatably arranged at the left and right ends of the extension arm respectively. There are two linkage belts, and the two linkage belts are respectively wound around the two runners. The two ends of the linkage belt wound around the left runner are respectively arranged at the right end of the mounting arm and the right end of the holding arm, and the two ends of the linkage belt wound around the right runner are respectively arranged at the left end of the mounting arm and the left end of the holding arm.

[0044] The vehicle body 100 is provided with a storage plate 110, and two mounting arms 120 respectively located at the front and rear sides of the storage plate 110, the mounting arm 120 is provided with an extension arm 400 that can slide in the left and right directions, the extension arm 400 is provided with a holding arm 500 that can slide in the left and right directions, the extension arm 400 and the holding arm 500 are both located above the storage plate 110, and the left and right ends of the holding arm 500 are both provided with a first driving member 610, and the first driving member 610 can drive the abutment block 611 thereon to rotate to an avoidance state or a push state, and the linkage assembly 200 is provided with two, one of which is slidably arranged in sequence. The mounting arm 120, an extension arm 400 and an arm 500 are all connected to a linkage assembly 200, the transmission assembly 300 is arranged on the vehicle body 100, the two extension arms 400 are all connected to the transmission assembly 300, the second driving member 620 is arranged on the vehicle body 100, the second driving member 620 is connected to the transmission assembly 300, and the second driving member 620 can drive the two extension arms 400 to move left or right synchronously through the transmission assembly 300, wherein the extension arm 400 that moves left or right can drive the arm 500 thereon to move left or right accordingly through the linkage assembly 200.

[0045] It can be understood that the abutment block 611 in the avoidance state can avoid the object, so that the object can be moved between the two arms 500.

[0046] It can be understood that a mounting arm 120, an extension arm 400 and a holding arm 500 which are slidably arranged in sequence are all connected to a linkage assembly 200. For details, refer to Figure 2 One of the mounting arms 120, one of the extension arms 400 and one of the holding arms 500, all located on the front side, are slidably arranged in sequence and are all connected to one of the linkage components 200; another mounting arm 120, another extension arm 400 and another holding arm 500, all located on the rear side, are slidably arranged in sequence and are all connected to another linkage component 200.

[0047] When the shuttle moves to the preset position of the stereoscopic warehouse, the process of the shuttle removing the items on one side of the left and right sides of the shuttle is as follows (taking the removal of the left side items as an example, refer to Figure 1): 1. The two first driving members 610, both located at the left end, drive the two abutting blocks 611 thereon to rotate to the avoidance state; 2. The second driving member 620 drives the two extension arms 400 to move to the left synchronously through the transmission assembly 300. At this time, the two extension arms 400 that move to the left synchronously drive the two holding arms 500 thereon to move further to the left through the two linkage assemblies 200, so that the object is placed between the two holding arms 500, and the two abutting blocks 611, both located at the left end and in the avoidance state, are moved to the left side of the object; 3. The two first driving members 610, both located at the left end, drive the two abutment blocks 611 thereon to rotate to the pushing state; 4. The second driving member 620 drives the two extension arms 400 to move right and retract synchronously through the transmission assembly 300. At this time, the two extension arms 400 that move right and retract synchronously drive the two holding arms 500 thereon to further move right and retract through the two linkage assemblies 200, so that the two abutment blocks 611, both located at the left end and in the pushing state, push the objects located between the two holding arms 500 to move the objects to the storage plate 110.

[0048] When the shuttle moves to the preset position of the stereoscopic warehouse, the process of the shuttle moving the items on it to one of the left and right sides of the shuttle is as follows (taking the transfer of items to the left side of the shuttle as an example, refer to Figure 1 ): 1. The two first driving members 610, both located at the right end, drive the two abutment blocks 611 thereon to rotate to the pushing state; 2. The second driving member 620 drives the two extension arms 400 to move leftward and extend synchronously through the transmission assembly 300. At this time, the two extension arms 400 that move leftward and extend synchronously drive the two holding arms 500 thereon to further move leftward and extend through the two linkage assemblies 200, so that the two abutment blocks 611, both located at the right end and in the pushing state, push the objects on the storage plate, so that the objects located between the two holding arms 500 are moved to the left side of the shuttle.

[0049] Through the above structure, on the one hand, the second driving member 620 can drive the two extension arms 400 to move left or right synchronously through the transmission assembly 300, so as to synchronously drive the two holding arms 500 to move left or right through the two linkage assemblies 200. In other words, the shuttle vehicle of the present application uses one driving member, one transmission assembly 300 and one linkage assembly 200 to cooperate to make the two holding arms 500 move synchronously. Therefore, compared with the traditional shuttle vehicle, the shuttle vehicle of the present application uses a small number of driving members to drive the two holding arms 500 to move synchronously, so it can effectively reduce the production cost; on the other hand, the extended extension arm 400 that moves out can drive the holding arm 500 thereon to further move out through the corresponding linkage assembly 200. In other words, on the basis of moving and extending with the extension arm 400, the holding arm 500 can still move and extend relative to the extension arm 400 under the action of the linkage assembly 200. Therefore, compared with the traditional shuttle vehicle, the holding arm 500 of the shuttle vehicle of the present application can move and extend a larger amount, so it can remove objects with longer specifications.

[0050] In this embodiment, the first driving member 610 is configured as a motor member.

[0051] The linkage assembly 200 includes a rotating wheel 210 and a linkage belt 220 .

[0052] Reference Figure 3 There are two rotating wheels 210, which are rotatably disposed at the left and right ends of the extension arm 400, and there are two linkage belts 220, which are respectively wound around the two rotating wheels 210. The two ends of the linkage belt 220 wound around the left rotating wheel 210 are respectively disposed at the right end of the mounting arm 120 and the right end of the holding arm 500, and the two ends of the linkage belt 220 wound around the right rotating wheel 210 are respectively disposed at the left end of the mounting arm 120 and the left end of the holding arm 500.

[0053] In this embodiment, refer to Figure 3 The rotating wheel 210 is provided with a first tooth portion 211 around its rotation axis, and the linkage belt 220 is provided with a second tooth portion 221 arranged along its length direction. The first tooth portion 211 of the rotating wheel 210 is meshed with the second tooth portion 221 of the linkage belt 220 wound around the rotating wheel 210.

[0054] Through the above structure, the probability of the linkage belt 220 slipping relative to the rotating wheel 210 can be reduced, so as to ensure that the arm 500 moves relative to the extension arm 400 under the action of the linkage assembly 200.

[0055] In this embodiment, refer to Figure 2 and Figure 3 The mounting arm 120 and the extension arm 400 , as well as the extension arm 400 and the holding arm 500 are all slidably connected via a slide bar assembly 700 .

[0056] The slider assembly 700 includes a first strip 710, a second strip 720, and a third strip 730.

The balls 721A located below are slidably arranged between the first limiting groove 711A and the second limiting groove 732 both located below. The two first limiting blocks 711B and the two second limiting blocks 731 are respectively arranged at the left and right ends of the second strip 720. Among them, the cross - sections of the first strip 710 and the second strip 720 are both in a C - shaped structure. The inner cavities of the first strip 710 and the second strip 720 are the first chute 711 and the second chute 721 respectively; for the slider assembly 700 between the mounting arm 120 and the extension arm 400, its first strip 710 is arranged on the mounting arm 120, and the third strip 720 is arranged on the extension arm 400; for the slider assembly 700 between the extension arm 400 and the holding arm 500, its first strip 710 is arranged on the extension arm 400, and the third strip 720 is arranged on the holding arm 500.

[0058] It can be understood that the balls 721A located above are slidably arranged between the first limiting groove 711A and the second limiting groove 732 both located above, that is, a sliding space is surrounded between the first limiting groove 711A and the second limiting groove 732 both located above, and the balls 721A located above are slidably arranged in this sliding space; similarly, the balls 721A located below are slidably arranged between the first limiting groove 711A and the second limiting groove 732 both located below, that is, a sliding space is also surrounded between the first limiting groove 711A and the second limiting groove 732 both located below, and the balls 721A located below are slidably arranged in this sliding space.

[0059] With the above - mentioned structure, in addition to the effect of being able to have a double - stroke direction, the slider assembly 700 also has the effects of compact structure, smooth sliding, large load - bearing capacity, and low deflection deformation.

[0060] In some embodiments, the slide assembly 700 between the mounting arm 120 and the extension arm 400 has a first strip 710 disposed on the extension arm 400 and a third strip 720 disposed on the mounting arm 120 ; the slide assembly 700 between the extension arm 400 and the holding arm 500 has a first strip 710 disposed on the holding arm 500 and a third strip 720 disposed on the extension arm 400 .

The two chain conditions 320 are arranged side by side, and the two chain conditions 320 are respectively meshed with the two gear conditions 800. The second driving member 620 is provided as a motor member. The second driving member 620 can drive one of the roller members 310 to rotate, so that the two chain conditions 320 operate and drive the two extension arms 400 to move left or right synchronously through the two gear conditions 800.

[0062] In this embodiment, refer to Figure 8 and Fig.10 The gear condition 800 is located at the bottom of the corresponding extension arm 400 , the storage plate 110 is provided with four avoidance holes 111 , and the chain condition 320 is passed through the corresponding two avoidance holes 111 to be partially placed above the storage plate 110 and engage with the corresponding gear condition 800 .

[0063] It can be understood that the chain condition 320 is passed through the corresponding two avoidance holes 111 to be partially placed above the storage plate 110 and engaged with the corresponding gear condition 800, that is, one of the chain conditions 320 is passed through two of the avoidance holes 111 to be partially placed above the storage plate 110 and engaged with one of the gear conditions 800, and the other chain condition 320 is passed through the other two avoidance holes 111 to be partially placed above the storage plate 110 and engaged with the other gear condition 800.

[0064] In order to reduce the probability of the chain member 320 and the tooth member 800 meshing with each other during operation, refer to Figure 2 , Fig.10 as well as Fig.11Two fourth bars 900 are provided on the top side of the storage plate 110, and the fourth bar 900 is provided with two guide grooves 910 arranged side by side.
