Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0053] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms "an" or "a" and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms "connected" or "linked" and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up," "down," "left," "right," etc., are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0054] Existing 3D piping technology is slow and cannot meet industry demands. After the material in the filling cylinder is used up by manual labor or a robotic arm, due to the high viscosity and low fluidity of red bean paste, a considerable amount of time is required before new material can be added through the dispensing cylinder. During this period, the robotic arm used for piping red bean paste can only standby. Because continuous material supply is not possible, the production efficiency of red bean paste piping is significantly reduced.

[0055] To address the aforementioned problems, the present invention provides an indexing lifting turntable device. The following is a detailed description of an embodiment of the indexing lifting turntable device of the present invention with reference to the accompanying drawings.

[0056] like Figure 1 and Figure 2 As shown, the indexing lifting turntable device of this embodiment includes: a base frame 100, a drive mechanism, a lifting mechanism, a rotating mechanism, and a material replenishment mechanism. The base frame 100 has an internal mounting cavity. The drive mechanism is fixedly connected to one side of the base frame 100. The lifting mechanism is disposed within the mounting cavity and connected to the drive mechanism, for moving up and down under the drive of the drive mechanism. The rotating mechanism is disposed within the mounting cavity and connected to both the lifting mechanism and the drive mechanism, for rotating around an axis under the drive of the drive mechanism. The material replenishment mechanism is disposed on the other side of the base and connected to the rotating mechanism. The material replenishment mechanism includes a cylinder turntable 530 for supporting multiple cylinders 600, for driving the cylinders 600 on the cylinder turntable 530 to lift and rotate under the drive of the lifting mechanism and the rotating mechanism.

[0057] Specifically, the rotary table 530 has two symmetrically arranged workstation holes at both ends for placing the material cylinders 600. In the initial state, the empty material cylinder 600 in one of the workstation holes is close to the bottom of the discharge cylinder 700 to receive material. After the material cylinder 600 is loaded, the drive mechanism can drive the rotating mechanism to rotate the material replenishment mechanism, so that the material cylinder 600 moves laterally to cut and separate the material, and rotates to the other material cylinder 600. At this time, the robot can remove the material-loaded material cylinder 600 and place an empty material cylinder 600 in the workstation hole. At the same time, the drive mechanism can also drive the lifting mechanism to lower the material replenishment mechanism so that the material-loaded material cylinder 600 on the material replenishment mechanism is away from the discharge cylinder 700. Since materials such as red bean paste are relatively viscous, after the discharge cylinder 700 stops feeding, some material will hang from the edge. The lifting mechanism lowering the material replenishment mechanism can effectively prevent excess material from adhering to the material replenishment mechanism, effectively eliminating the problem of abnormal component movement caused by sticky materials such as red bean paste.

[0058] When the rotating mechanism rotates the empty material cylinder 600 on another workstation hole of the material replenishment mechanism to directly below the discharge cylinder 700, the drive mechanism can drive the lifting mechanism to lift the material replenishment mechanism, so that the empty material cylinder 600 and the discharge cylinder 700 are tightly connected to receive material. This process is repeated to achieve continuous feeding of low-flow-rate materials such as red bean paste. This device integrates the lifting mechanism and the rotating mechanism below the material replenishment mechanism, realizing the lifting and rotation of the material replenishment mechanism, thereby completing continuous material replenishment, effectively improving the efficiency of material replenishment and increasing production efficiency.

[0059] like Figure 2 As shown, in one embodiment of the present invention, the driving mechanism includes: a motor bracket 210, a stepper motor 220, an input shaft 230, and a coupling 240. The motor bracket 210 is fixedly connected to the outer side of the base plate of the base frame 100. The stepper motor 220 is fixedly connected to the motor bracket 210. One end of the input shaft 230 is connected to the stepper motor 220, and the other end passes through the base plate of the base frame 100 and is rotatably connected to the top plate of the base frame 100. The coupling 240 is sleeved on the input shaft 230.

[0060] During the rotation and lifting of the material replenishment mechanism, the stepper motor 220 mounted on the motor bracket 210 drives the input shaft 230 to rotate, thereby rotating or lifting the rotation and lifting mechanisms. Since the material replenishment mechanism has multiple material cylinders 600, and materials such as bean paste are prone to dripping, the timing control accuracy of the rotation of the rotation mechanism and the lifting of the lifting mechanism is crucial when replenishing materials through the circulating material cylinders 600. The stepper motor 220 has excellent start-stop and reverse response, and because the accuracy of each step is between 3% and 5%, it does not accumulate errors from one step to the next, thus providing good positional accuracy and motion repeatability. This effectively controls the timing of the rotation of the rotation mechanism and the lifting of the lifting mechanism, ensuring timely material replenishment while preventing material dripping and waste.

[0061] Meanwhile, the two sets of couplings 240 installed on the input shaft 230 can effectively transmit motion and torque, ensuring the accuracy of the input shaft 230's movement. Furthermore, the couplings 240 between the stepper motor 220 and the input shaft 230 can effectively compensate for the misalignment between the stepper motor 220 and the drive rod input shaft 230. Therefore, when the input shaft 230 drives the rotating mechanism to rotate and the lifting mechanism to rise and fall, the vibration generated during the movement of the rotating and lifting mechanisms can be effectively reduced, improving the accuracy of the rotation and lifting, thus enabling timely and effective cyclic replenishment of multiple material cylinders 600 and significantly improving production efficiency.

[0062] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the lifting mechanism includes: a lifting cam 310, a lifting needle roller bearing 320, a connecting block 330, and a lifting shaft 340. The lifting cam 310 passes through the input shaft 230 and is formed as a cylinder concentric with the input shaft 230. The cylindrical lifting cam 310 has a groove forming an annular curve in its circumferential direction. The lifting needle roller bearing 320 is slidably connected within the groove and is used to rise and fall with the rotation of the lifting cam 310. One end of the connecting block 330 is fixedly connected to the lifting needle roller bearing 320. One end of the lifting shaft 340 is fixedly connected to the other end of the connecting block 330, and the other end is fixedly connected to the rotating mechanism.

[0063] Specifically, the lifting needle roller bearing 320, housed within a circular groove on the lifting cam 310, is fixedly connected at one end to a connecting block 330 connected to the lifting shaft 340, and slidably connected at the other end to the inner wall of the groove. When the drive mechanism rotates the input shaft 230 to rotate the lifting cam 310 on the input shaft 230, the lifting needle roller bearing 320 rises and falls with the rotation of the groove, thereby driving the lifting shaft 340 to rise and fall together via the connecting block 330. This allows control of the material replenishment mechanism above the lifting shaft 340. Simultaneously, because the grooves are connected end-to-end, the lifting needle roller bearing 320 continuously drives the lifting shaft 340 in its rising and falling motion within the groove, ensuring smooth operation of the lifting shaft 340 and effectively reducing vibration, preventing material overflow from the material cylinder 600. This effectively saves material.

[0064] In one embodiment of the present invention, the end of the connecting block 330 opposite to the lifting needle roller bearing 320 is provided with a threaded hole (not shown). The surface of the lifting shaft 340 is formed with threads that match the threaded through hole and is fixedly connected to the connecting block 330 by two sets of fixing bolts 341. The connection between the connecting block 330 and the lifting shaft 340 is effectively guaranteed by the threaded connection and the reinforcement by the two sets of fixing bolts 341, thereby ensuring the connection strength at the connection point between the connecting block 330 and the lifting shaft 340, so as to smoothly and effectively transmit motion. This allows the lifting shaft 340 to keep its lifting and lowering in sync with the lifting needle roller bearing 320 during lifting and lowering, thereby effectively controlling the lifting and lowering time of the material replenishment mechanism and fully ensuring the timeliness of material replenishment.

[0065] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the rotating mechanism includes: an indexing gear 410, a turret disc 420, and a plurality of indexing needle roller bearings 430. The indexing gear 410 is sleeved on the input shaft 230 and located between the lifting cam 310 and the first deep groove ball bearing 251; the turret disc 420 is sleeved on the lifting shaft 340 and fixedly connected to the lifting shaft 340, and the turret disc 420 is fixedly connected to the material replenishment mechanism; the plurality of indexing needle roller bearings 430 are spaced apart axially on the turret disc 420 for driving the turret disc 420 to rotate under the drive of the indexing gear 410.

[0066] like Figure 5 As shown, in one embodiment of the present invention, the indexing gear 410 includes: a gear body 411, a first rim 412 and a second rim 413 connected end-to-end with the first rim 412 respectively formed on the axial direction of the gear body 411, the first rim 412 being formed as an arc tangent to each two indexing needle roller bearings 430, and a plurality of teeth being spaced apart on the second rim 413, the gap between the teeth and each two indexing needle roller bearings 430 meshing with the indexing gear 410.

[0067] Specifically, the lengths of the first rim 412 and the second rim 413 are equal. When the material cylinder 600 in one of the workstation holes on the cylinder turntable 530 is loaded with material, multiple teeth on the second rim 413 of the indexing gear 410 will be tangential to multiple indexing needle roller bearings 430 on the lower surface of the turret plate 420. When the indexing gear 410 is driven to rotate by the drive mechanism, the teeth on the second rim 413 will push the indexing needle roller bearings 430 to drive the turret plate 420 to rotate, thereby causing the material cylinder 600 to move laterally to cut and separate the material, and rotate to another material cylinder 600. Then, the indexing gear 410 rotates mechanically so that the first rim 412 is tangential to the multiple indexing needle roller bearings 430. At this time, the material replenishment mechanism stops rotating, and the robot can remove the material-loaded material cylinder 600 and place a new material cylinder 600 in the workstation hole. After the robotic arm removes the material-loaded cylinder 600 and places a new cylinder 600, the indexing gear 410 is driven to rotate by the drive mechanism. This causes the gear teeth on the second rim 413 to mechanically push the indexing needle roller bearing 430 to rotate the turret disc 420, thereby aligning the empty cylinder 600 in the other workstation hole with the discharge port. Thus, the rotation of the material replenishment mechanism is controlled by the cooperation of the indexing gear 410 and the indexing needle roller bearing 430. The control method is simple, and time is reserved for the robotic arm to remove the material-loaded cylinder 600 and replace it with a new one. This achieves cyclical material replenishment through rotation, effectively improving production efficiency.

[0068] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the material replenishment mechanism includes an embedded bearing housing 510 and a turret shaft 520. The embedded bearing housing 510 is fixedly connected to the base frame 100, and a bearing is disposed at the center of the embedded bearing housing 510. The turret shaft 520 passes through the bearing, with one end fixedly connected to the turret disc 420 and the other end fixedly connected to the turntable mounting base 512. The material cylinder turntable 530 is disposed on the turntable mounting base 512, and the turret shaft 520 is used to drive the material cylinder turntable 530 to rotate under the drive of the turret disc 420.

[0069] Specifically, one end of the turret shaft 520, which passes through the embedded bearing housing 510, is fixedly connected to the turret disc 420 via a round nut 511, while the other end has a square tenon. The bottom of the turntable mounting base 512 has a fixing hole that matches the square tenon. Thus, the turntable mounting base 512 can be mounted on the square tenon through the fixing hole and detachably fixed to the turret shaft 520. It can then rotate with the turret disc 420 to drive the rotation of the material cylinder turntable 530, realizing the rotary cyclic feeding of the material replenishment mechanism and effectively improving production efficiency. Furthermore, when the material cylinder turntable 530 needs to be modified or upgraded, only the turntable mounting base 512 needs to be pulled out to modify or upgrade the material cylinder turntable 530 without the need for hot work or cutting. This effectively saves construction time.

[0070] like Figure 2 As shown, in one embodiment of the present invention, the drive mechanism further includes a first deep groove ball bearing 251 and a second deep groove ball bearing 252. The first deep groove ball bearing 251 passes through the input shaft 230 and is fixedly connected to the bottom plate of the base frame 100. The second deep groove ball bearing 252 passes through the input shaft 230 and is fixedly connected to the top plate of the base frame 100. Specifically, since the input shaft 230 does not directly contact the bottom plate and top plate of the base frame 100, and the lifting cam 310 and indexing gear 410 on the input shaft 230 need to be linked with the turret 420 and lifting shaft 340 on the other side to generate a change in the center of gravity, the input shaft 230 will shift when the stepper motor 220 drives the input shaft 230 to rotate at high speed. Therefore, a first deep groove ball bearing 251 and a second deep groove ball bearing 252 can be respectively fitted onto the input shaft 230 and fixedly connected to the bottom plate and top plate of the base frame 100, thereby fixing the input shaft 230 in the vertical direction and eliminating the problem of input shaft 230 offset. This effectively prevents equipment failure caused by input shaft 230 offset and improves the service life of the device.

[0071] like Figure 2 As shown, in one embodiment of the present invention, the driving mechanism further includes: a first tensioning block 253, a first positioning bolt (not shown), a second tensioning block 254, and a second positioning bolt (not shown). The first tensioning block 253 is arranged parallel to the first deep groove ball bearing 251, and a first threaded through hole is provided on the side of the tensioning block near the first deep groove ball bearing 251; the first positioning bolt passes through the first threaded through hole and is used to tighten the first deep groove ball bearing 251 horizontally; the second tensioning block 254 is arranged parallel to the second deep groove ball bearing 252, and a second threaded through hole is provided on the side of the tensioning block near the second deep groove ball bearing 252; the second positioning bolt passes through the second threaded through hole and is used to tighten the second deep groove ball bearing 252 horizontally.

[0072] Specifically, when the stepper motor 220 drives the input shaft 230 to rotate, the input shaft 230 rotates at a high speed. The first deep groove ball bearing 251 and the second deep groove ball bearing 252, which are mounted on the input shaft 230, will vibrate under the high-speed rotation of the input shaft 230, causing them to shift along with the input shaft 230. Therefore, a first tension block 253 and a second tension block 254 can be respectively provided, and the first positioning bolt and the second positioning bolt can be used to horizontally tighten the first deep groove ball bearing 251 and the second deep groove ball bearing 252, thereby effectively limiting the lateral shift of the input shaft 230. This further reduces the possibility of equipment failure caused by the shift of the input shaft 230 and extends the service life of the device.

[0073] like Figure 1 and Figure 3 As shown, in one embodiment of the present invention, the material cylinder turntable 530 is provided with at least two station holes for accommodating the material cylinder 600. Specifically, two station holes are symmetrically arranged at both ends of the material cylinder turntable 530, so that the material cylinder turntable 530 can be rotated by a rotating mechanism to align the material cylinder 600 in the station hole with the discharge cylinder 700. It is worth noting that the number and position of the station holes can also be changed according to the number and position of the discharge cylinder 700.

[0074] like Figure 2 and Figure 4 As shown, in one embodiment of the present invention, the indexing lifting turntable device further includes: a first connecting collar 231 and a second connecting collar 232. The first connecting collar 231 is sleeved on the input shaft 230 and disposed between the first deep groove ball bearing 251 and the lifting cam 310 for fixing the lifting cam 310; the second connecting collar 232 is sleeved on the input shaft 230 and disposed between the second deep groove ball bearing 252 and the indexing gear 410 for fixing the indexing gear 410. Specifically, since the lifting cam 310 and the indexing gear 410 are relatively heavy, and both the lifting cam 310 and the indexing gear 410 need to be linked with the turret 420 and the lifting shaft 340 on the other side to cause a change in the center of gravity, thus causing displacement, the first connecting collar 231 and the second connecting collar 232 are respectively provided on the input shaft 230 to fasten the lifting cam 310 and the indexing gear 410 to the input shaft 230. This effectively prevents the lifting cam 310 and indexing gear 410 from shifting due to changes in the center of gravity, thus avoiding abnormal movement of the lifting shaft 340 and turret 420, and further extending the service life of the device.

[0075] The indexing lifting turntable device of the present invention controls the lifting and rotation of the material replenishment mechanism through a lifting mechanism and a rotating mechanism within the base frame 100, so that the two workstation holes on the material replenishment mechanism's cylinder turntable 530 can rotate and lift repeatedly, thereby allowing the material cylinder 700 to continuously replenish material to the material cylinder 600 in the workstation hole, realizing automated and continuous material supply, shortening the replenishment interval, and effectively improving production efficiency.

[0076] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
