It should be noted that, in the description of the present embodiment, the material a may refer to the material itself, or may refer to a material tank containing the material a. The first direction Y refers to the height direction of the gantry 1. The conveying unit 2 continuously moves between the first material inlet and outlet 11 and the second material inlet and outlet 12, which means that the conveying unit continuously moves, for example, continuously rises or continuously falls, that is, the continuous lifting machine of the embodiment moves the material a in the carrying surface on the basis of ensuring that the conveying unit 2 continuously moves in the height direction, so as to convey the material a. The movement of the material a in the bearing surface along the second direction X may refer to conveying the material a from the outside of the rack 1 into the inside of the rack 1, where the third material inlet/outlet 13 is a feed inlet, or conveying the material a from the inside of the rack 1 out of the outside of the rack 1, where the third material inlet/outlet 13 is a discharge outlet.

Also in the embodiment shown in fig. 1, the material inlets and outlets are located on the same side of the frame 1. In other embodiments not shown in the drawings, the material inlets and outlets may be located on different sides of the rack.

The material inlet and outlet of the embodiment refers to the area of the continuous lifting machine corresponding to the space between two adjacent floors. The conveying unit 2 reaching the target material inlet/outlet in the first direction Y means reaching an area belonging to the target material inlet/outlet, for example reaching a lower end of the third material inlet/outlet during the ascending of the conveying unit 2, and for example reaching an upper end of the third material inlet/outlet during the descending of the conveying unit 2.

As shown in fig. 1, the continuous lifting machine 1 of the present embodiment includes a first material inlet/outlet 11, a second material inlet/outlet 12, and a third material inlet/outlet 13 corresponding to three floors, respectively. The three material inlets and outlets are used for conveying materials with the production line of the corresponding floor. The three material inlets and outlets can be used as a material outlet and a material inlet. In the related art known to the utility model, the materials are all input or output from the first material inlet/outlet 11 and the second material inlet/outlet 12 located at the end portions. However, the material transfer from the third material inlet/outlet 13 located in the middle is not disclosed, and the third material inlet/outlet 13 will be described as the target material inlet/outlet with emphasis on the following description, but the present invention protects a continuous hoisting machine that can also use the first material inlet/outlet 11 and the second material inlet/outlet 12 as the target material inlet/outlet.

The continuous elevator of the embodiment comprises a plurality of conveying units 2, and the plurality of conveying units 2 continuously operate between a first material inlet and outlet 11 and a second material inlet and outlet 12. When carrying material, as shown in fig. 1, the conveyor units 2 are placed horizontally to run between different floors; when empty at the end of the output of the material, the conveyor unit 2 is placed vertically to switch direction in the machine frame 1 to enter the next work flow, as shown in fig. 2.

As shown in fig. 3 to 8, the conveying unit 2 of the present embodiment includes a plurality of rollers 21 sequentially arranged along the second direction X and a timing belt 23 arranged between two adjacent rollers 21, wherein a first engaging portion is arranged on an end roller located at an end of the plurality of rollers 21, and the first engaging portion and the second engaging portion are engaged to rotate the end roller and drive other rollers of the plurality of rollers to synchronously rotate. The conveying unit 2 of this embodiment includes a plurality of rollers 21 arranged in sequence, and rotation of one of the rollers 21 can drive other rollers 21 to rotate synchronously so that the material on the surface moves on the surface thereof to complete conveying of the material. The first engagement portion is provided on the end roller, so that the first engagement portion can be easily brought into contact with and engaged with the second engagement portion provided on the frame 1 during the lifting or lowering of the conveying unit 2, thereby simplifying the layout of the elevator.

Specifically, as shown in fig. 7 and 8, the end roller of the present embodiment is provided with a gear 22 forming a first fitting portion, and the gear 22 is provided coaxially with the end roller.

In this embodiment, the end roller includes a roller body and a roller shaft disposed at an end of the roller body, and the outer surface of the roller shaft is splined to form the gear 22. That is, the gear 22 of the present embodiment is integrally formed on the drum shaft. In other embodiments not shown in the drawings, the gear may also be a separate component and attached to the drum shaft.

A synchronous belt 23 is arranged around the roller shaft between every two adjacent rollers 21. In order to keep the distance between two adjacent rollers 21 of the present embodiment constant, the conveying unit 2 of the present embodiment further includes a chain plate structure 24 disposed between two adjacent rollers 21. The chaining plate structure 24 includes a housing and a chain disposed within the housing. The provision of the chain plate structure 24 also allows the conveyor unit 2 to ensure the spacing between adjacent rollers when cornering.

As shown in fig. 3 to 5, the rack assembly 3 of the present embodiment includes a rack 31 disposed at the third material inlet/outlet 13 of the frame 1 and extending along the first direction Y to form a second matching portion, and the gear 22 is engaged with the rack 31, and when the conveying unit 2 moves along the rack 31 under the driving of the driving device 20, the gear 22 rotates to drive the end roller to rotate. When the conveying unit 2 rises to enable the end roller to be close to the rack 31, the gear 22 is meshed with the rack 31, the rack 31 is kept still, the conveying unit 2 is driven by the driving mechanism 20 to continuously rise, then the end roller is driven to rotate by the meshing of the rack 31 and the gear 22, the end roller rotates to drive other rollers to rotate through the synchronous belt 23, and therefore the rollers of the whole conveying unit obtain kinetic energy to convey the material A loaded on the rollers 21 of the conveying unit 2 to the conveying platform.

In other embodiments not shown in the figures, the first and second cooperating portions may also be cams and sliders or worm wheels and worms.

Since the conveying unit 2 of the present embodiment is continuously moved during the lifting or lowering process, the time for conveying the materials by the conveying unit 2 is less than the time for moving the conveying unit 2 on the rack 31, so as to ensure that the materials are completely conveyed.

Specifically, the time that the conveying unit passes through the rack 31 in the first direction Y is defined as a first moving time, and the moving time that the material a moves in the carrying surface of the conveying unit 2 in the second direction X is defined as a second moving time, and in order to ensure that the conveying of the material a is completed smoothly in the process of ascending or descending of the conveying unit 2, the first moving time is longer than the second moving time.

However, for the materials a with different lengths in the second direction X, the second moving time on the conveying unit 2 is different, so the position of the rack 31 needs to be adjusted according to the length of the materials a and the moving speed of the conveying unit 2 in the first direction Y. In order to adjust the position of the rack 31, the rack assembly 3 of the present embodiment is movably disposed in the first direction Y with respect to the frame 1. Of course, the raising or lowering speed of the conveyance unit 2 may be adjusted by controlling the operation of the driving device 20.

In this embodiment, the continuous lifting machine further comprises a controller 5 coupled to the rack assembly 3, wherein the controller 5 controls whether the rack assembly 3 moves in the first direction Y according to the length of the material a in the second direction X.

When the length of the material a is long, the controller controls the rack 31 to move upwards from the original height, and after the rack 31 is meshed with the gear 22, the controller controls the rack 31 to move downwards so that the rack 31 moves in the reverse direction relative to the gear 22 to accelerate the rotation of the drum, and the second moving time is shortened to finish the conveying of the material. So set up and make the lifting machine of this embodiment can carry in order to improve the application scope of the lifting machine of this embodiment to material A of equidimension not.

The upper end surface of the rack 31 of the present embodiment includes an inclined surface.

As shown in fig. 11 and 12, the rack assembly 3 of the present embodiment includes two racks 31 respectively located at both sides in the width direction of the conveying unit 2, and both ends of the end drum of the conveying unit 2 are provided with the gears 22 to respectively engage with the two racks 31.

The rack gear assembly 3 of the present embodiment further includes a support plate 32 located at a bottom end of the rack gear 31 and a connection plate 33 located between the two rack gears 31 to connect the two rack gears 31.

In order to ensure stable conveyance of the conveying unit of the present embodiment, the continuous lifting machine of the present embodiment includes two rack assemblies 3 respectively located on both sides of the frame 1 in the second direction X. In order to better ensure that the conveying unit 2 can smoothly complete the conveying of the materials, the elevator of the embodiment further comprises a receiving platform 4. As shown in fig. 1, the receiving platform 4 is disposed outside the rack 1 and corresponds to the third material inlet/outlet 13. The receiving platform 4 is arranged on the floor plate 17 of the third material inlet and outlet 13. As shown in fig. 9 and 10, in some embodiments, the lower end of the rack 31 extends beyond the lowermost end of the receiving platform 4 so that the gear 22 of the end roller begins to mesh with the rack 31 earlier. The material is conveyed from the inside of the frame 1 to the outside of the frame 1.

In the present embodiment in particular, the lower end of the rack 31 extends to the lower surface of the floor panel 17.

The receiving platform 4 of the present embodiment is provided at an end thereof adjacent to the frame 1 so as to be liftable in the first direction Y. The upper end of the rack 31 is raised to the highest position beyond the end of the receiving platform 4 adjacent to the frame 1. The arrangement ensures that the gear of the conveying unit 2 is always meshed with the rack 31 in the process of butting the conveying unit 2 with the bearing platform 4.

Since the third material inlet/outlet 13 of the present embodiment is an optional material inlet/outlet, the rack assembly 3 only needs to function when the material needs to be delivered through the third material inlet/outlet 13. Therefore, when the material is not required to be delivered at the third material inlet/outlet 13, the rack assembly 3 is located away from the frame 1 to prevent the gear 22 on the drum 21 from engaging with the rack 31; when the material needs to be delivered at the third material inlet/outlet 13, the rack assembly 3 moves to a position close to the rack 1 so that the gear 22 is engaged with the rack 31 to complete the delivery of the material. That is, the rack assembly 3 is normally located at a position away from the rack 1, and only when the third material inlet/outlet 13 is a target material inlet/outlet, the rack assembly 3 moves to a position close to the rack 1 to perform its function.

Furthermore, the continuous lift of the present embodiment comprises at least one third material inlet/outlet 13. When one of the at least one third material inlet/outlet 13 is used as a target material inlet/outlet, the rack assembly 3 corresponding to the target material inlet/outlet is moved.

In order to achieve the above function, the rack assembly 3 of the present embodiment is movably disposed in the second direction X with respect to the housing 1.

Specifically, the continuous lifting machine further comprises a controller 5 coupled with the rack assembly 3, the controller 5 controls whether the rack assembly 3 moves according to a target material inlet and outlet of the material, and if the target material inlet and outlet of the material is a first material inlet and outlet 11 or a second material inlet and outlet 12, the controller 5 controls the rack assembly 3 to be kept at a position far away from the rack 1; if the target material inlet and outlet of the material is the third material inlet and outlet 13, the controller 5 controls the rack assembly 3 to move towards the direction close to the rack 1.

In order to realize the movement of the rack assembly 3 in the first direction Y and the second direction X, as shown in fig. 11, the continuous elevator of the present embodiment further includes a first driving mechanism 6 for driving the rack assembly 3 to move in the second direction X and a second driving mechanism 7 for driving the rack assembly 3 to move in the first direction Y. Wherein the first drive mechanism 6 is located on a side of the support plate 32 remote from the frame 1. The second drive mechanism 7 is located between the support plate 32 and the connecting plate 33. The support plate 32 of the present embodiment is an L-shaped plate. The first drive mechanism 6 is connected to the vertical section of the L-shaped plate.

In order to prevent the conveying unit 2 of the present embodiment from vibrating due to contact with the rack assembly 3, as shown in fig. 12, in another embodiment, a buffer 8 is provided between the first driving mechanism 6 and the support plate 32. Specifically, the first drive mechanism 6 of the present embodiment is a cylinder. A spring is provided between the piston rod of the cylinder and the support plate 32.

As shown in fig. 13 and 14, the housing 1 of the present embodiment is further provided with a groove 16 for guiding the movement of the rack assembly 3. The groove 16 has a first directional section and a second directional section. The rack assembly 3 moves along the groove 16.

As shown in fig. 17, the hoist of the present embodiment further includes a transmission chain 9 provided between the driving device 20 and the conveying unit 2. Four corners of the conveying unit 2 are connected with transmission chains 9. In order to prevent the conveying unit 2 from contacting the rack assembly 3 and being pressed inward by the rack assembly 3 to cause deformation of the transmission chain, the elevator of the embodiment further includes a limiting wheel 10 disposed outside the transmission chain 9.

As shown in fig. 1, the continuous lifting machine of this embodiment further includes a receiving platform 4 disposed at the third material inlet/outlet 13. The receiving platform 4 is arranged on a floor plate 17 on the outer side of the frame 1 and is arranged corresponding to the third material inlet and outlet 13. As shown in fig. 15 and 16, an end of the receiving platform 4 close to the frame 1 is movably disposed in the first direction Y to smoothly abut against the carrying surface of the transporting unit 2 when the carrying surface of the transporting unit 2 transports the material a. During the process of the conveyor unit 2 outputting the material a out of the frame 1, when a part of the material a has left the conveyor unit 2 while another part still stays on the conveyor unit 2, the end of the receiving platform 4 is smoothly butted against the end of the conveyor unit 2 to enable the material a to be smoothly conveyed.

Specifically, in the process of shifting the center of gravity of the material a, the up-and-down movement of the end of the receiving platform 4 close to the rack 1 in the first direction Y is synchronized with the up-and-down movement of the conveying unit 2 in the first direction Y. The arrangement is such that the receiving platform 4 and the conveying unit 2 are smoothly butted in the transfer process of the materials A to ensure the stable conveying of the materials A. When the conveying unit 2 ascends, the gravity center of the material A is completely transferred to the conveying surface of the receiving platform 4 before the bearing surface of the conveying unit 2 is completely separated from the material A in the gravity center transferring process between the conveying unit 2 and the receiving platform 4. When the conveying unit 2 is lowered, the center of gravity of the material a is completely transferred to the carrying surface of the conveying unit 2 before the conveying surface of the receiving platform 4 is completely separated from the material a.

And the receiving platform 4 of the embodiment is a belt conveying platform. In other embodiments not shown in the figures, the receiving platform is a roller conveying platform. And the conveying surface of the receiving platform 4 moves synchronously and in the same direction with the bearing surface of the conveying unit 2.

As shown in fig. 15 and 16, the receiving platform 4 is arranged to be raised and lowered at one end thereof adjacent to the frame 1. When the third material inlet and outlet 13 needs to output materials, one end of the receiving platform 4 close to the rack 1 rises synchronously with the conveying unit 2 so that the bearing surface of the receiving platform 4 becomes an inclined surface. When the material a is conveyed to the third material inlet and outlet 13 by the roller of the conveying unit 2, the gravity center of the material a is still on the conveying unit 2, and as the material slides onto the belt of the receiving platform 4, the gravity center of the material a can complete the transfer from the conveying unit 2 to the receiving platform 4 with the highest point of the inclined surface of the receiving conveying platform 4 as a fulcrum. As the conveyor unit 2 continues to be lifted, the tail of the material a will naturally tilt and accelerate the movement of the centre of gravity to the receiving platform 4. That is, the inclined surface of the receiving platform 4 of the present embodiment is provided such that the material a naturally and smoothly moves from the conveying unit 2 onto the receiving platform 4.

As shown in fig. 15 and 16, the receiving platform 4 of the present embodiment includes a first platform 41 close to the frame 1, a second platform 12 far from the frame 1, and a third driving mechanism 43 provided on the lower side of the first platform 41. The first platform 41 is rotatably connected to the second platform 42. The third driving mechanism drives the first platform 41 to rotate relative to the second platform 42 so as to incline the first platform 41.

The third driving mechanism 43 is a telescopic driving mechanism such as an air cylinder or an oil cylinder.

The height range of the up-and-down movement of one end of the receiving platform 4 in this embodiment is smaller than the height range of the third material inlet/outlet 13. The lowermost end of the receiving platform 4 rests on the floor plate 17 so that the height of the uppermost point of the elevation of one end of the receiving platform 4 is less than the height of the upper end of the third material inlet/outlet 13.

The operation of the third material inlet/outlet 13 as a discharge port according to the embodiment of the present invention will be described in detail with reference to fig. 18 to 20.

When the third material inlet/outlet 13 is a material outlet, the rack assembly 3 is driven by the first driving mechanism 6 to move along the second direction X to approach the rack 1 and move to a position where it can be engaged with the conveying unit 2.

The transport unit 2 is moved upward within the frame 1 by the drive of the drive device 20. As shown in fig. 18, when the conveying unit 2 moves to the position of the third material inlet and outlet 13, the gear 22 of the end roller thereof engages with the rack 31 and continues to move upward under the driving of the driving device 20, so that the end roller rotates to convey the material a outward. At this time, the receiving platform 4 is still horizontally disposed.

As shown in fig. 19, while the conveying unit 2 continues to move upwards, the material a moves outwards under the driving of the roller of the conveying unit 2, and in the process, the end part of the receiving platform 4 close to the frame 1 synchronously rises along with the conveying unit 2 to incline the belt surface part of the receiving platform 4, and the gravity center of the material a is still on the conveying unit 2. As the conveying unit 2 continues to output the material a outwards and the conveying unit 2 continues to lift upwards, as shown in fig. 20, the material a is moved out by the conveying unit 2, and the material a inclines to one side of the receiving platform 4 and gets closer to the belt surface of the receiving platform 4 with the highest position of the receiving platform 4 as a fulcrum. When the tail of the material a rises to the highest and completely leaves the conveying unit 2, the center of gravity of the material a is completely received by the receiving platform 4 and continues to be conveyed downwards under the drive of the belt of the receiving platform 4.

As shown in fig. 18 to 20, the lifting speed of the receiving platform 4 and the lifting speed of the conveying unit 2 are synchronized to make the material a slide smoothly between the conveying unit 2 and the receiving platform 4.

The operation of the third material inlet/outlet 13 as a feed inlet according to the embodiment of the present invention will be described in detail with reference to fig. 21 to 23.

As shown in fig. 21, the end of the receiving platform 4 adjacent to the frame 1 is first raised to the highest so that the conveying surface of the receiving platform 4 is inclined and the material a reaches its highest under the conveyance of the receiving platform 4. The delivery unit 2 completes the engagement with the rack assembly 3 during the lowering process. As shown in fig. 22, the material a moves to the side of the conveyor unit 2 by the belt of the receiving platform 4, and part of the material a has already separated from the receiving platform 4. The conveyor unit 2 continues to descend and one end of the receiving platform 4 also descends synchronously so that the material a can be transferred between the two smoothly. As shown in fig. 23, the material a has now moved completely onto the conveyor unit 2 and, as shown in fig. 24, has been brought into the interior of the frame 1 by the conveyor unit 2. The continuous elevator also comprises a human-computer interaction operation platform and a controller coupled with the human-computer interaction operation platform, the human-computer interaction operation platform is configured to input a target material inlet and outlet, and the controller receives the target material inlet and outlet and controls whether the bearing surface moves according to the target material inlet and outlet.

In some embodiments, the material is provided with an electronic tag, the electronic tag records a target material inlet and outlet of the material, and the man-machine interaction console scans the electronic tag to input the target material inlet and outlet.

Specifically, the material a of this embodiment is provided with an electronic tag, and the electronic tag records a target material inlet and outlet of the material a. Specifically, an RFID chip can be arranged outside the material box, and all the warehouse-in materials have material codes. And all the materials have set production workshops and floors. When transporting the upper and lower floor of material through the lifting machine at every turn, use the material serial number of RFID on the electron gun scanning material case and material incasement earlier, when the material case passes through the lifting machine feed inlet like this, the FRFID detection device who sets up at the feed inlet will detect the workshop floor that the material should be carried automatically. The controller can automatically trigger the auxiliary conveying equipment at the material inlet and outlet of the floor of the part production workshop to move to a preset position for standby. Therefore, when the materials are lifted to the position of the appointed floor, the waiting auxiliary conveying equipment drives the conveying unit 2 to automatically convey the materials to move to the corresponding material inlet and outlet. The plurality of material inlets and outlets can simultaneously operate under the unified control of the controller to respectively output corresponding materials to the belt of the receiving platform 4 from the set floor. The belt of the bearing platform 4 is connected with a conveying device of the stereoscopic warehouse, and materials are automatically conveyed to the position of the stereoscopic warehouse for storage.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
