[0072] The utility model will be further described below in conjunction with the accompanying drawings.

[0073] The embodiment of the utility model provides a lifting and transplanting device, which comprises a lifting mechanism 3 and a carrying and transporting mechanism 1.

[0074] The carrying and transporting mechanism 1 comprises a mounting frame 11 and a transmission chain 12 mounted on the mounting frame 11 . The transmission chain 12 is used to carry the product to be transported and can realize forward and reverse transport of the product by forward and reverse rotation.

[0075] The lifting mechanism 3 is connected to the carrying and transporting mechanism 1. The lifting mechanism 3 includes a moving part and a matching part that cooperate with each other. One end of the moving part is connected to the mounting frame, and the other end extends downward and cooperates with the matching part, so that the moving part moves up and down under the drive of the matching part.

[0076] As described above, this embodiment uses the matching parts to drive the moving parts to move up and down, thereby driving the overall up and down movement of the carrying and transporting mechanism 1, ensuring the stability and reliability of the lifting and lowering of the carrying and transporting mechanism 1. In addition, the transmission chain 12 can realize the forward and reverse transportation of the product through forward and reverse rotation, thereby facilitating the product to move from the multi-layer speed chain to the transmission chain 12, and the product to move out of the transmission chain 12.

[0077] The lifting and transplanting device further comprises a base 2 , which is located below the carrying and transporting mechanism 1 and is used for installing a lifting mechanism 3 and a driving transmission mechanism 4 .

[0078] The jacking mechanisms are arranged in at least two groups, the at least two groups of jacking mechanisms are arranged at intervals, and the at least two groups of jacking mechanisms are driven by the same driving transmission mechanism 4.

[0079] It can be understood that the driving transmission mechanism 4 is connected to at least two groups of lifting mechanisms 3, so that the driving transmission mechanism 4 can drive the moving parts in at least two groups of lifting mechanisms 3 to move up and down at the same time, so that the carrying and transporting mechanism 1 can be stably lifted up and down under the drive of multiple groups of lifting mechanisms 3, thereby enhancing the stability of the lifting and lowering movement of the carrying and transporting mechanism 1.

[0080] As an embodiment, the moving part is a rack, and the matching part is a gear meshing with the rack. The gear rotates to drive the rack up and down, thereby driving the carrying and transporting mechanism 1 to move up and down as a whole. The driving transmission mechanism can be a motor, a hydraulic mechanism or a cylinder driving mechanism.

[0081] As another embodiment, the moving part is a lead screw 31, and the matching part is a ball pair 32; one end of the lead screw 31 is fixedly mounted on the mounting frame 11, and the other end extends downward and is connected to the ball pair 32 on the base 2. The ball pair 32 can be a bearing, the outer ring of the bearing is fixedly mounted on the base 2 as a stator, and the inner ring of the bearing is mounted on the lead screw 31 as a rotor.

[0082] The driving transmission mechanism 4 is arranged on the base 2. The driving transmission mechanism 4 is connected to the ball pair 32 and can rotate on the base 2 by driving the ball pair 32 to drive the lead screw 31 connected to the ball pair 32 to move up and down along its own axial direction relative to the ball pair 32, thereby driving the mounting frame 11 installed and connected to the lead screw 31 and the transmission chain 12 on the mounting frame 11 to move up and down.

[0083] The driving transmission mechanism 4 includes a worm gear assembly and a driving assembly.

[0084] The worm gear assemblies are arranged in one-to-one correspondence with the lifting mechanism 3, and at least two sets of worm gear assemblies are drivingly connected to the driving assembly.

[0085] The structure and driving method of the drive transmission mechanism 4 are described below by taking the arrangement of two groups of worm and gear assemblies as an example.

[0086] Both sets of worm gear assemblies include a worm gear 41 and a worm gear 42 that mesh with each other. The two worm gears are extended transversely and are arranged on the left and right sides of the drive assembly. The two worm gears 42 are connected to the drive assembly in a transmission manner. The worm gear 42 meshes with the worm gear 41 for transmission. The worm gear 42 is coaxially fixedly installed with the ball pair 32, and the ball pair 32 is connected to the lead screw 31 in a transmission manner.

[0087] It can be understood that the driving assembly can drive the worm 42 on the left and right sides to rotate around the central axis. The rotation of the worm 42 drives the turbine 41 meshing with it to rotate, and drives the ball pair 32 to rotate through the turbine 41, and drives the screw 31 to move up and down through the rotation of the ball pair 32, thereby driving the carrying and transporting mechanism 1 to move up and down.

[0088] In this embodiment, the driving assembly includes a commutator 43 and a first motor 44 connected thereto. The commutator 43 has an input shaft and two coaxially arranged output shafts.

[0089] The two output shafts of the commutator 43 are extended transversely and fixedly installed coaxially with the two worm gears 42 in a one-to-one correspondence. The output shaft of the commutator 43 is connected to the worm gears 42 via a first coupling 45 .

[0090] The input shaft of the commutator 43 extends in the up-down direction and is connected to the output shaft of the first motor 44 via a second coupling 46 .

[0091] It can be understood that the first motor 44 is connected to the two worm gears 42 through the commutator 43. The first motor 44 drives the input shaft of the commutator 43 to rotate, the steering gear reverses the transmission direction, and the two output shafts of the commutator 43 drive the two worm gears 42 to rotate simultaneously.

[0092] The commutator 43 in the present application is prior art, and the present embodiment does not further limit its structure. For example, the specific structure of the commutator 43 can refer to the commutator disclosed in the Chinese utility model patent (authorization announcement number: CN204517103U).

[0093] Of course, the worm gear assembly and the lifting mechanism 3 can also be arranged in three, four or more groups, which is not further limited in this embodiment.

[0094] In this embodiment, there are at least two transmission chains 12 arranged in parallel, and each transmission chain 12 is installed on the mounting frame 11 through a driving sprocket and a driven sprocket meshing therewith; at least two transmission chains 12 can rotate in the same direction to cooperate in transporting the products thereon. When all the transmission chains 12 move in the forward direction, the products can be transported in the forward direction; when all the transmission chains 12 rotate in the reverse direction, the products can be transported in the reverse direction.

[0095] The carrying and transporting mechanism 1 in this embodiment further includes a driving shaft 13 and a second transmission assembly drivingly connected to the driving shaft 13 .

[0096] The driving shaft 13 extends along the spacing direction of each transmission chain 12 . A plurality of driving sprockets are fixedly mounted on the same driving shaft 13 . The plurality of driving sprockets are arranged in one-to-one correspondence with the plurality of transmission chains 12 and are meshed and transmitted.

[0097] It can be understood that the drive shaft 13 can synchronize the movements of multiple transmission chains 12: the drive shaft 13 rotates forward or reversely under the drive of the second transmission component, and the rotation of the drive shaft 13 can drive multiple driving sprockets installed thereon to rotate forward or reversely at the same time, thereby driving the transmission chains 12 meshing with the driving sprockets to rotate in the same direction at the same time.

[0098] The second transmission assembly specifically includes a driving wheel 14, a driven wheel 15, and a chain 16 for connecting the driving wheel 14 and the driven wheel 15. The driving wheel 14 is connected to the output shaft of the second motor 17; the driven wheel 15 is fixedly mounted on the driving shaft 13; and both the driving wheel 14 and the driven wheel 15 are meshed with the chain 16 for transmission.

[0099] Therefore, the second motor 17 can drive the rotating wheel to rotate, and the driving wheel 14 drives the driven wheel 15 to rotate through the chain 16, and the rotation of the driven wheel 15 can drive the driving shaft 13 to rotate.

[0100] In this embodiment, the lifting and transplanting device also includes a cover plate 5 installed on the mounting frame 11. The cover plate 5 is located between two adjacent transmission chains 12 and covers the driving shaft 13, the driving wheel 14, the driven wheel 15, the chain 16, and the second motor 17.

[0101] It can be understood that the cover plate 5 can cover the drive shaft 13 and the second transmission assembly to prevent the drive shaft 13 and the second transmission assembly from being exposed, which can not only achieve an aesthetic effect, but also protect the drive shaft 13 and the second transmission assembly from falling dust. For example, if dust enters the second motor 17, it may affect the use of the second motor 17, and the cover plate 5 can prevent dust from entering the second motor 17.

[0102] The carrying and transporting mechanism 1 also includes a sprocket tensioning assembly 6 for tensioning the transmission chain 12. The sprocket tensioning assembly 6 is connected to the driven sprocket of the transmission chain 12 and can adjust the tightness of the transmission chain 12 by adjusting the driven sprocket of the transmission chain 12 to be close to or away from the driving sprocket.

[0103] The lifting and transplanting device in this embodiment further includes a guide mechanism 7 for providing guidance for the upward and downward movement of the lead screw 31 and the carrying and transporting mechanism 1 . The guide mechanism 7 includes a sliding sleeve 71 and a guide rod 72 .

[0104] The sliding sleeve 71 is fixedly mounted on the mounting frame 11, and has a sliding cavity extending in the up-down direction; one end of the guide rod 72 is mounted on the mounting frame 11, and the other end extends downward and passes through the sliding sleeve 71 to slide up and down with the sliding cavity of the sliding sleeve 71. Optionally, the sliding sleeve 71 is a sliding bearing.

[0105] As described above, by providing a guide rod 72 on the mounting frame 11 and providing a sliding sleeve 71 on the mounting frame 11 that slides up and down with the guide rod 72, the mounting frame 11 can slide up and down along the sliding cavity of the sliding sleeve 71 along with the guide rod 72, thereby enhancing the stability of the mounting frame 11 when lifting and lowering.

[0106] The guide mechanisms 7 are arranged in multiple groups, and the multiple groups of guide mechanisms 7 are arranged at intervals along the circumference of the mounting frame 11. Preferably, the guide mechanisms 7 can be arranged in four groups, and the four groups of guide mechanisms 7 are arranged at the four corners of the mounting frame 11 in a one-to-one correspondence.

[0107] The lifting and transplanting device further comprises a blocking mechanism 8 arranged on one side of the mounting frame 11 along the length direction of the conveying chain, and the blocking mechanism 8 is used to block and limit the product or the tray 300 on the conveying chain.

[0108] The lifting and transplanting device also includes a controller and a sensor arranged on the blocking mechanism 8, and the sensor is used to detect whether the product to be transported or the pallet 300 is placed on the conveying chain.

[0109] The sensor, the power components of the transmission chain 12, and the drive transmission mechanism 4 are all electrically connected to the controller, and the controller is used to control the forward and reverse rotation of the transmission chain 12 and control the lifting mechanism 3 to perform lifting actions.

[0110] The blocking mechanism 8 includes two vertical plates 81 mounted on the mounting frame 11 ; the sensor is arranged on the vertical plates 81 .

[0111] The present embodiment also provides a multi-layer double-speed chain 200 line system, including the aforementioned lifting and transplanting device, and also including a multi-layer double-speed chain 200 arranged up and down, at least one layer of the multi-layer double-speed chain 200 is transported along a first direction, and at least one layer of the double-speed chain is transported along a second direction opposite to the first direction.

[0112] There are at least two lifting and transplanting devices, and the plurality of lifting and transplanting devices are arranged on both outer sides of the multi-layer speed chain 200 along the length direction.

[0113] The following is an example of setting up two lifting and transplanting devices.

[0114] One lifting and transferring device is used to transfer the upper layer of the product to be transported downward, and the other lifting and transferring device is used to transfer the product to be transported upward. The two lifting and transferring devices are used to lift and transfer the product between the double-speed chains that transport the product in opposite directions, so that the product can flow back between the multiple layers of double-speed chains 200.

[0115] As an implementation method, the number of multi-layer speed chains 200 is three layers, which are divided into upper, middle and lower layers, wherein the upper speed chain 201 is transported along a first direction, and the middle speed chain 202 and the lower speed chain 203 are transported along a second direction. For example, when the first direction is from right to left, the second direction is from left to right; similarly, when the first direction is from left to right, the second direction is from right to left.

[0116] The working principle of the three-layer double-speed chain line system in the above implementation is as follows:

[0117] The products placed on the upper double-speed chain 201 are moved along the first direction driven by the upper double-speed chain 201, and the transmission chain 12 of the first lifting and transplanting device 110 located on the left side of the upper double-speed chain 201 is also transported along the first direction;

[0118] When the product moves onto the transmission chain 12 of the first lifting and transplanting device 110, the vertical plate 81 at the end of the mounting frame 11 limits the tray 300 to prevent the product placed on the tray 300 from falling; at the same time, the sensor installed on the vertical plate 81 can detect the product, and the controller controls the first motor 44 to stop, so that the transmission chain 12 stops;

[0119] Then, the controller controls the second motor 17 to rotate to drive the lifting mechanism 3 to descend, thereby driving the carrying and transporting mechanism 1 to descend to a height corresponding to the middle-layer double-speed chain 202 or the lower-layer double-speed chain 203;

[0120] Then, the controller controls the first motor 44 to reverse, so that the transmission chain 12 is transported in the first direction, so that the product on the transmission chain 12 is transported to the middle-layer double-speed chain 202 or the lower-layer double-speed chain 203, and the middle-layer double-speed chain 202 and the lower-layer double-speed chain 203 drive the product to move in the second direction and approach the second lifting and transplanting device 120 located on the other side of the multi-layer double-speed chain 200;

[0121] Similarly, the second lifting and transplanting device 120 is used to transport the products on the middle-layer double-speed chain 202 and the lower-layer double-speed chain 203 to the upper-layer double-speed chain 201;

[0122] The products are circulated in sequence, thus realizing the transportation and backflow between the three-layer speed chains.

[0123] When one of the middle-layer speed chain 202 and the lower-layer speed chain 203 is overloaded, the other one of the middle-layer speed chain 202 and the lower-layer speed chain 203 can be used to cooperate with the upper-layer speed chain 201 to carry out backflow transportation of the products, and the middle-layer speed chain 202 and the lower-layer speed chain 203 can be protected from overload.

[0124] In addition, when the chain 16 of one of the middle-layer speed chain 202 and the lower-layer speed chain 203 is broken, the other one of the middle-layer speed chain 202 and the lower-layer speed chain 203 can be used to work normally, and the speed chain can be repaired after the production operation is completed, so as not to delay production.

[0125] It is conceivable that there may be other implementations. For example, when the number of multi-layer speed chains 200 is three, the upper speed chain 201 and the middle speed chain 202 are both transported along the first direction, and the lower speed chain 203 is transported along the second direction.

[0126] Of course, the number of multi-layer speed chains 200 can also be set to four layers, five layers or more layers.

[0127] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
