Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of soft porcelain production, and particularly relates to a soft porcelain unloading and stacking device. BACKGROUND

[0002] At present, soft porcelain needs to be stacked and transferred in the processes of forming, drying, edge grinding and warehousing. Since soft porcelain has rubber-like softness, which is different from the hard texture of traditional porcelain, it cannot be stacked in the conventional way of plate materials in the transfer process, for example, the continuous stacking mode in the automatic plate stacking machine of CN109095191A. If such a stacking mode is adopted, the surface of the soft porcelain is prone to scratching, affecting the quality of production. Therefore, the current soft porcelain unloading and stacking work is basically carried out by using a traditional multi-degree-of-freedom manipulator to absorb the soft porcelain through a suction cup. Although this unloading and stacking mode can realize the unloading of soft porcelain one by one and protect the soft porcelain, the overall equipment cost is high, the control system is required to be high, and the unloading and stacking efficiency is low.

[0010] Further, the ratio between the radius of the driving shaft and the thickness of the soft porcelain at one end of the output direction of the second belt is less than 6:1.

[0011] Further, a plurality of second winding wheels are arranged on the two driving shafts, and all the second belts are wound around the corresponding second winding wheels of the two driving shafts in parallel; the ratio between the diameter of the second winding wheel at one end of the output direction of the second belt and the thickness of the soft porcelain is less than 5:1.

[0012] Further, a plurality of discharge wedge blocks are arranged on one end of the sliding frame in the output direction of the second belt, and a roller is rotatably installed on each discharge wedge block; the outer periphery of the roller penetrates and extends out of both sides of the discharge wedge block.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] See Figures 1 to 7This application provides a soft porcelain feeding and stacking device, including a frame 100, a horizontal conveying mechanism 200, a telescopic conveying mechanism 300, a drive mechanism 400, a universal telescopic transmission mechanism 500, and a lifting and stacking mechanism 600; the horizontal conveying mechanism 200 is mounted on the frame 100; the telescopic conveying mechanism 300 is slidably mounted on the frame 100, and the telescopic conveying mechanism 300 is used to receive the soft porcelain output by the horizontal conveying mechanism 200; the drive mechanism 400 is mounted on the frame 100 and outputs... The input end of the telescopic transmission mechanism 300 is connected to the input end of the horizontal conveying mechanism 200; the input end of the universal telescopic transmission mechanism 500 is connected to the output end of the drive mechanism 400 or the rotating structure of the horizontal conveying mechanism 200, and its output end is connected to the input end of the telescopic conveying mechanism 300; the lifting and stacking mechanism 600 is used to receive the soft porcelain output by the telescopic conveying mechanism 300; the telescopic conveying mechanism 300 can extend into the lifting and stacking mechanism 600 to gradually spread the soft porcelain conveyed on it on the receiving end of the lifting and stacking mechanism 600.

[0034] In this application, the drive mechanism 400 can be a conventional servo motor, and its output end can be connected to the input end of the horizontal conveyor mechanism 200 via a coupling. The horizontal conveyor mechanism 200 can be a conventional belt conveyor mechanism.

[0035] This flexible ceramic feeding and stacking device features a horizontal conveyor mechanism 200 to receive flexible ceramics from an external conveyor line, facilitating adjustment of the conveying speed and adapting to the movement of the telescopic conveyor mechanism 300. Utilizing the sliding design of the telescopic conveyor mechanism 300 on the frame 100, after receiving the flexible ceramics output from the horizontal conveyor mechanism 200, the telescopic conveyor mechanism 300 can extend into the lifting and stacking mechanism 600 to gradually lay the conveyed flexible ceramics flat within it. During this laying process, it gradually retracts from the lifting and stacking mechanism 600. This design solves the problem of friction between the flexible ceramics and the conveyor belt or stacking equipment during the stacking process, which can damage the surface of the flexible ceramics, and also ensures that the flexible ceramics are laid flat and stacked evenly. A universal telescopic transmission mechanism 500 is designed for transmission, adapting to the transmission requirements of the telescopic conveyor mechanism 300 which undergoes continuous displacement. Furthermore, the universal telescopic transmission mechanism 500 allows for the simultaneous driving of the horizontal conveyor mechanism 200 and the telescopic conveyor mechanism 300 using a single drive mechanism 400, reducing equipment costs. The lifting and stacking mechanism 600 in this application can be a conventional...

[0036] See Figures 1 to 2In one embodiment of this application, to facilitate the receiving of soft porcelain from external equipment, such as drying equipment or molding equipment, the horizontal conveying mechanism 200 includes two rotating shafts 220 rotatably mounted on the frame 100 and several first belts 230 wound around the two rotating shafts 220. Rotating wheels 210 are rotatably mounted on the rotating shafts 220 at the output end, located in the area between two adjacent first belts 230. One end of any rotating shaft 220 is connected to the output end of the drive mechanism 400. Several second belts 340 are rotatably mounted on the telescopic conveying mechanism 300, with the upper portions of all second belts 340 passing over the corresponding rotating wheels 210. The soft porcelain conveyed on the first belts 230 can be smoothly received by the second belts 340 and driven forward.

[0037] The telescopic conveyor mechanism 300 is equipped with a second belt 340 that bypasses the corresponding rotating wheel 210. This design allows for a direct connection between the input end of the telescopic conveyor mechanism 300 and the output end of the first belt 230, with no gap between them. This facilitates the smooth transfer of soft ceramic from the first belt 230 to the second belt 340. In practical use, to prevent slippage between the soft ceramic and either the first or second belt 340 due to speed differences, the telescopic conveyor mechanism 300 and the horizontal conveyor mechanism 200 are designed to operate synchronously. Specifically, during installation, the output end of the drive mechanism 400 is directly connected to either rotating shaft 220 or connected to the input end of the telescopic conveyor mechanism 300 via a universal telescopic transmission mechanism 500. This universal telescopic transmission mechanism 500 enables synchronous rotation of the rotating shaft 220 and the telescopic conveyor mechanism 300, ensuring that both the first belt 230 and the second belt 340 move synchronously and have the same conveying speed.

[0038] Furthermore, the rotating wheel 210 and the corresponding rotating shaft 220 can rotate relative to each other. This design allows the telescopic conveyor mechanism 300 to automatically adapt to the movement of the telescopic conveyor mechanism 300 through the relative sliding movement between the second belt 340 and the rotating wheel 210 when it extends forward.

[0039] See Figure 3 and Figure 4In the above-described improved embodiment, in order to facilitate the adaptation of the structural design of the horizontal conveying mechanism 200, the telescopic conveying mechanism 300 includes a telescopic driver 310, a sliding frame 320, and a drive shaft 330 rotatably mounted on both ends of the sliding frame 320. A plurality of second belts 340 are provided and respectively wound around the two drive shafts 330. The sliding frame 320 is slidably mounted on the frame 100 along the conveying direction of the horizontal conveying mechanism 200. The telescopic driver 310 is mounted on the frame 100 and its output end is connected to the corresponding end of the sliding frame 320. All the second belts 340 in the upper region between the two drive shafts 330 pass around the corresponding rotating wheel 210. One end of any drive shaft 330 is connected to the output end of the universal telescopic transmission mechanism 500.

[0040] The second belt 340 has a triangular structure when viewed from the side, with the two drive shafts 330 forming the two corners of the base, and the rotating wheel 210 serving as the apex of the triangle. Specifically, in this application, the sliding frame 320 can be displaced relative to the horizontal conveying mechanism 200; that is, in actual use, the two drive shafts 330 can be displaced relative to the rotating wheel 210. After the sliding frame 320 slides out relative to the frame 100 along the conveying direction of the soft porcelain, the second belt 340 will drive the rotating wheel 210 to rotate relative to the rotating shaft 220. At this time, with the sliding frame 320 as the observation reference, the rotating wheel 210 will move in the opposite direction of the conveying direction. Conversely, when the sliding frame 320 slides back into the frame 100 along the opposite direction of the soft porcelain conveying direction, with the sliding frame 320 as the observation reference, the rotating wheel 210 will move in the direction of the conveying direction. In fact, because the second belt 340 is triangular in shape when viewed from the side, when the soft porcelain is conveyed on the second belt 340, it forms an angle with the stacking platform surface of the lifting and stacking mechanism 600 or the upper surface of the already stacked soft porcelain. This design is beneficial because the downward end of the soft porcelain, after extending out of the second belt 340, is the first to contact the stacking platform surface of the lifting and stacking mechanism 600 or the upper surface of the already stacked soft porcelain. At this time, as the second belt 340 continues to convey the soft porcelain and the sliding frame 320 retracts, the conveyed soft porcelain, due to its own weight and its own flexibility, is further conveyed. The soft ceramic is gradually laid flat on the stacking platform surface of the lifting and stacking mechanism 600 or on the upper surface of the already stacked soft ceramic. The retraction action of the sliding frame 320 counteracts the inertial force exerted by the second belt 340 on the soft ceramic during the conveying process. During this process, the soft ceramic being conveyed on the second belt 340 and the stacking platform of the lifting and stacking mechanism 600 are in a relatively static state. Therefore, the newly laid soft ceramic will not slip on the stacking platform surface of the lifting and stacking mechanism 600 or on the upper surface of the already stacked soft ceramic, avoiding scratches. At the same time, the soft ceramic is stacked in a flat laying manner, resulting in good overall stacking quality.

[0041] Furthermore, in the above embodiments, when the sliding frame 320 slides out relative to the frame 100 along the conveying direction of the soft porcelain, the soft porcelain can stay on the first belt 230 or on the second belt 340 before being conveyed to the lifting and stacking mechanism 600. When the soft porcelain rests on the first belt 230, the sliding frame 320 slides out relative to the frame 100 along the conveying direction of the soft porcelain and gradually enters the lifting and stacking mechanism 600. At this time, the output end of the drive mechanism 400 rotates, and the soft porcelain on the first belt 230 can be gradually transferred to the second belt 340 until the soft porcelain is conveyed to its output end by the second belt 340. At this time, the sensor installed on the end of the sliding frame 320 can detect feedback and then control the telescopic driver 310 to retract, thereby driving the sliding frame 320 to gradually retract into the frame 100. At this time, in conjunction with the conveying action of the second belt 340, the soft porcelain can be directly and gradually laid flat on the stacking platform of the lifting and stacking mechanism 600. In the whole process, the soft porcelain and the stacking platform, or the second belt 340, will not actually slip too much, thus largely eliminating the possibility of scratches. After the soft ceramic tile is completely resting on the second belt 340, the sliding frame 320 slides out relative to the frame 100 along the conveying direction of the soft ceramic tile and gradually enters the lifting and stacking mechanism 600. The soft ceramic tile is then conveyed to its output end by the second belt 340. At this point, based on feedback from the sensor installed at the end of the sliding frame 320, the telescopic driver 310 is controlled to retract, thereby causing the sliding frame 320 to gradually retract into the frame 100. Combined with the conveying action of the second belt 340, the soft ceramic tile can be directly and gradually laid flat on the stacking platform of the lifting and stacking mechanism 600. Therefore, whether the soft ceramic tile rests on the first belt 230 or the second belt 340, the above function can be achieved without any relative displacement of the soft ceramic tile relative to the first belt 230 or the second belt 340 during the conveying process, which would cause scratches to the soft ceramic tile.

[0042] It should be further noted that in actual use, the length of the flexible ceramic tile must be less than the length of the first belt 230 and the second belt 340. This is crucial to prevent relative displacement of the flexible ceramic tile relative to the first belt 230 or the second belt 340 during transport. Specifically, in this embodiment, as the second belt 340 transports forward while the sliding frame 320 gradually retracts, the very front end of the flexible ceramic tile is already in contact with the limiting structure on the stacking platform of the lifting and stacking mechanism 600 or the top layer of flexible ceramic tile already stacked. Therefore, during the entire transport process, the flexible ceramic tile will not continue to move forward due to inertia. Unlike patent CN109095191A - Automatic Stacking Machine, where the board material is received by a temporary receiving device after being output from the conveyor belt, causing the board material to slip relative to the temporary receiving device, the flexible ceramic tile will not slip as it does in this case. Nor will it be intercepted by a limiting baffle at the front end of the conveyor belt in the output direction, as is the traditional method, where the board material will slip relative to the receiving end during its fall, resulting in scratches and wear.

[0043] Furthermore, in the above-described improved embodiment, in order to enable the soft ceramic on the second belt 340 to contact the stacking platform of the lifting and stacking mechanism 600 or the already stacked soft ceramic more quickly after being output, the ratio between the radius of the second belt 340 at its output end that wraps around the drive shaft 330 and the thickness of the soft ceramic is less than 6:1. The main purpose of this design is to reduce the relative height between the output soft ceramic and the stacking platform of the lifting and stacking mechanism 600 or the already stacked soft ceramic, which helps to reduce the deviation of the newly stacked soft ceramic when it falls onto the stacking platform or the already stacked soft ceramic, ensuring the stacking effect. In the actual stacking process, the soft ceramic on the second belt 340 needs to extend one end beyond the corresponding end of the second belt 340. At this time, the outward end of the soft ceramic is flush with the corresponding side of the stacking platform of the lifting and stacking mechanism 600, rather than the corresponding end of the second belt 340 being flush with the corresponding side of the stacking platform of the lifting and stacking mechanism 600. When the outward end of the flexible ceramic is aligned with the side of the stacking platform of the lifting and stacking mechanism 600, the telescopic driver 310 controls the sliding frame 320 to gradually retract. In this way, the flexible ceramic's own deflection allows its outward end to gradually stack on the stacking platform of the lifting and stacking mechanism 600 or on the flexible ceramic that has already been stacked in place.

[0044] Furthermore, in actual production applications, the second belt 340 is generally not directly mounted on the drive shaft 330. Instead, it is typically wound around one of the pulleys on the drive shaft 330. Specifically, both drive shafts 330 are provided with several second pulleys 350, and all the second belts 340 are wound parallel to each other on the corresponding second pulleys 350 of the two drive shafts 330. The ratio between the diameter of the second pulley 350 located at the output direction end of the second belt 340 and the thickness of the soft ceramic is less than 5:1.

[0045] See Figure 5 In the above-described improved embodiment, to reduce the excessive gap between the outward end of the soft ceramic after it is output from the second belt 340 and the stacking platform of the lifting and stacking mechanism 600 or the upper surface of the already stacked soft ceramic, which can easily lead to inaccurate positioning of newly stacked soft ceramic, in an improved embodiment of this application, the sliding frame 320 is provided with a plurality of discharge wedges 360 at one end of the second belt 340 in the output direction. Each discharge wedge 360 ​​is rotatably mounted with a roller 370, the outer periphery of which extends through and beyond both sides of the discharge wedge 360. The rollers 370 are mainly provided to avoid scratches caused by relative friction between the discharge wedge 360 ​​and the already stacked soft ceramic and the newly conveyed soft ceramic.

[0046] See Figure 1 and Figure 6 To achieve synchronous rotation of the drive shaft 330 and the rotating shaft 220 while simultaneously changing the direction of transmission, in one embodiment of this application, the universal telescopic transmission mechanism 500 includes a telescopic shaft 510 and universal joints 520 connected to both ends of the telescopic shaft 510. The telescopic shaft 510 is capable of telescopic extension and retraction along its axial direction. The other end of any one of the universal joints 520 is connected to the output end of the drive mechanism 400, and the other end of the remaining universal joints 520 is connected to the input end of the telescopic conveying mechanism 300. In this embodiment, the axial direction of the drive mechanism 400 is parallel to the axial directions of the drive shaft 330 and the rotating shaft 220. In order to ensure that the telescopic shaft 510 has sufficient installation space and the installation space required for transmission, the connection point between the output end of the drive mechanism 400 and the rotating shaft 220 needs to be relatively far apart. This way, the corresponding universal joint 520 can be directly connected to the corresponding end of the drive shaft 330.

[0047] Of course, in some improved embodiments, the rotating end of the universal joint 520 is connected to the middle of the drive shaft 330 via a belt, so that a compact installation can be achieved.

[0048] In another embodiment of this application, for the purpose of compact installation, a steering gear 530 is connected to the outward end of each of the two universal joints 520. The two steering gears 530 are respectively connected to the input end of the telescopic conveying mechanism 300 and the output end of the drive mechanism 400. The design of the steering gears 530 allows the output end of the drive mechanism 400 to directly and short-distance connect to the rotating shaft 220 while simultaneously transmitting power to the drive shaft 330. This two-stage steering transmission via the two steering gears 530 ensures that the drive mechanism 400, while directly driving the rotating shaft 220, also rotates synchronously through the telescopic shaft 510 and the universal joints at both ends, maintaining a compact structure. It should be noted that the steering gear is a conventional structure, containing a pair of meshing bevel gears, thus achieving a 90° turn; details of this will not be elaborated upon here.

[0049] See Figure 6 It should be further explained that, during the process of the telescopic actuator 310 driving the sliding frame 320 to extend out of the frame 100, the telescopic shaft 510 gradually becomes longer. In order to achieve this function, in one embodiment of this application, the telescopic shaft 510 includes a main rod 511 and a secondary cylindrical rod 512. One end of the secondary cylindrical rod 512 is fitted onto one end of the main rod 511. The universal joint 520 is connected to the outward end of both the secondary cylindrical rod 512 and the main rod 511. A protruding rib 513 is provided axially on the outer wall of the end of the main rod 511 that mates with the secondary cylindrical rod 512. A sliding groove that mates with the protruding rib 513 is provided on the secondary cylindrical rod 512. In this embodiment, when the telescopic actuator 310 drives the sliding frame 320 to extend out of the frame 100, since the drive mechanism 400 is fixedly mounted on the frame 100, in order to realize the transmission between the drive mechanism 400 and the drive shaft 330, the main rod 511 and the auxiliary rod 512 move in opposite directions along their respective axial directions, which makes the entire telescopic shaft 510 longer. When the telescopic actuator 310 drives the sliding frame 320 to retract back into the frame 100, the main rod 511 and the auxiliary rod 512 move towards each other along their respective axial directions, which shortens the entire telescopic shaft 510. However, whether the telescopic shaft 510 is longer or shorter, due to the mating structure of the convex rib 513 and the sliding groove, the two can only move along the axial direction, and when rotating around their own axis, they rotate synchronously.

[0050] See Figure 7In one embodiment of this application, the lifting and stacking mechanism 600 includes a support 610, a lifting platform 620, and a lifting assembly disposed on the support 610. The lifting platform 620 is mounted on the lifting end of the lifting assembly. A carrying conveyor belt 640 is rotatably mounted on the lifting platform 620. A conveyor belt 630 is disposed on one side of the support 610 located on the lifting platform 620. The lifting assembly can drive the lifting platform 620 to descend to be flush with the conveying plane of the conveyor belt 630. The carrying conveyor belt 640 can transport the stacked soft ceramics to the conveyor belt 630.

[0051] The lifting platform 620 is a regular platform structure. To ensure the stacked flexible ceramic tiles can be placed onto the carrier conveyor belt 640 during the actual stacking process, a limit baffle is installed on one side of the lifting platform 620. In actual use, for each stacked flexible ceramic tile, the lifting component lowers the lifting platform 620 by the thickness of one tile. This design ensures that the height difference between the flexible ceramic tile conveyed by the second belt 340 and the stacked flexible ceramic tile on the carrier conveyor belt 640 remains constant, which helps control the stacking quality and reduces the risk of scratching the flexible ceramic tiles. The carrier conveyor belt 640 is connected to the conveyor motor 650 via a chain or belt. Similarly, the conveyor belt 630 is also connected to the external delivery motor 660 via a chain or belt. The conveyor motor 650 is mounted on the lifting platform 620, while the external delivery motor 660 is mounted on the bracket 610.

[0052] It should be noted that the lifting assembly uses a conventional screw motor structure. Specifically, a lifting motor is mounted on the bracket 610, which drives a nut on the bracket 610 to rotate. A screw is rotatably mounted inside the nut, and the upper end of the screw is connected to the back of the lifting platform 620. This structural design enables precise lifting. In some improved embodiments, the lifting assembly can also have a lifting motor on the bracket 610. The lifting motor drives a lifting shaft on the bracket 610 to rotate. A sprocket is mounted on the lifting shaft, and a chain is wound around the sprocket. The chain is connected to the lifting platform 620, and the rotation of the lifting shaft drives the chain to rise or fall, thereby achieving the lifting of the lifting platform 620.

[0053] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
