Description

Technical Field

[0001] This utility model relates to the field of soft porcelain processing technology, specifically to a soft porcelain feeding and conveying device. Background Technology

[0002] Currently, flexible ceramics require transfer and even stacking during processing steps such as forming, drying, edge grinding, and warehousing. Due to its rubber-like softness, unlike the hard texture of traditional ceramics, flexible ceramics cannot be stacked using conventional sheet-like methods, such as the continuous feeding and stacking method in the CN109095191A automatic stacking machine. Traditional stacking methods easily scratch the surface of the flexible ceramics, affecting production quality. Therefore, the current feeding and stacking of flexible ceramics primarily uses traditional multi-degree-of-freedom robotic arms that use suction cups for feeding, in conjunction with external stacking equipment. While this method allows for sheet-by-sheet feeding and protects the ceramics, the overall equipment cost is high, the control system requirements are demanding, and the feeding and stacking efficiency is low. Therefore, there is an urgent need for a continuous feeding device to work in conjunction with external stacking equipment to achieve efficient feeding and stacking of flexible ceramics. Utility Model Content

[0008] Furthermore, the telescopic shaft includes a main rod and a secondary rod, one end of the secondary rod is fitted onto one end of the main rod, and the universal joint is connected to the outward end of both the secondary rod and the main rod; a convex ridge is provided axially on the outer wall of the end of the main rod that mates with the secondary rod, and a sliding groove that mates with the convex ridge is provided on the secondary rod.

[0009] Furthermore, the telescopic conveying mechanism includes a telescopic driver, a sliding frame, drive shafts rotatably mounted on both ends of the sliding frame, and several second belts wound around the two drive shafts. The sliding frame is slidably mounted on the frame along the conveying direction of the horizontal conveying mechanism. The telescopic driver is mounted on the frame and its output end is connected to one end of the sliding frame. Several rotating wheels are rotatably provided on the output end of the horizontal conveying mechanism. All the second belts in the upper region between the two drive shafts pass over the corresponding rotating wheels. One end of any drive shaft is connected to the output end of the universal telescopic transmission mechanism.

[0010] Furthermore, the ratio between the radius of the second belt at its output end that wraps around the drive shaft and the thickness of the soft ceramic is less than 6:1.

[0011] Furthermore, each of the two drive shafts is provided with a plurality of second pulleys, and all the second belts are respectively wound in parallel on the corresponding second pulleys of the two drive shafts. The ratio between the diameter of the second pulley located at one end of the output direction of the second belt and the thickness of the soft ceramic is less than 5:1.

[0012] Furthermore, the sliding frame is provided with a plurality of discharge wedge blocks at one end in the output direction of the second belt, and each discharge wedge block is rotatably mounted with a roller, the outer periphery of the roller extending through and out of both sides of the discharge wedge block.

[0013] Furthermore, the horizontal conveying mechanism includes two rotating shafts rotatably mounted on the frame and several first belts wound around the two rotating shafts.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 only used to explain this utility model and are not intended to limit this utility model.

[0031] See Figures 1 to 6 This application provides a soft porcelain feeding and conveying device, including a frame 100, a horizontal conveying mechanism 200, a telescopic conveying mechanism 300, a drive mechanism 400, and a universal telescopic transmission mechanism 500; 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, and the output end of the telescopic conveying mechanism 300 can extend outward; the drive mechanism 400 is mounted on the frame 100 and its output end 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 output end of the telescopic conveyor mechanism 300 cooperates with the external stacking device A to receive the soft porcelain output by the telescopic conveyor mechanism 300. In actual use, the telescopic conveyor mechanism 300 can extend into the external stacking device A to gradually lay the soft porcelain it is conveying onto the receiving end of the external stacking device A. The external stacking device A is actually an automatically lifting structure that adapts to the movement of the telescopic conveyor mechanism 300, realizing the functions of unloading, laying, and stacking the soft porcelain. For ease of explanation, the external stacking device A is represented by the reference numeral A in this application.

[0032] 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. The external stacking equipment A in this application can be a conventional lifting and palletizing device, such as the technical solutions in patent CN118529325A - A palletizing lifting platform and its constituent sheet metal packaging precision control palletizing system, or CN209259102U - A lifting palletizing device; these will not be detailed here.

[0033] This flexible ceramic feeding and conveying 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 external stacking equipment A to gradually lay the conveyed flexible ceramics flat within the equipment. During this laying process, it gradually withdraws from the stacking equipment A. 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, while also ensuring a flat and evenly stacked arrangement. The universal telescopic transmission mechanism 500 is designed for transmission to meet the transmission requirements of the telescopic conveyor mechanism 300 which is constantly shifting. In addition, the universal telescopic transmission mechanism 500 can also achieve the effect of simultaneously driving the horizontal conveyor mechanism 200 and the telescopic conveyor mechanism 300 with a single drive mechanism 400, thereby reducing equipment costs.

[0034] See Figures 1 to 2 In 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.

[0035] 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.

[0036] 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.

[0037] See you again Figure 1 To facilitate adjustment of the tension of the first belt 230, in one embodiment of this application, an adjusting stud 110 is screwed onto one end of the frame 100. A mounting head 120 is provided on the outward-facing end of the adjusting stud 110, and the corresponding rotating shaft 220 is rotatably mounted on the mounting head 120. In practice, a rotating nut that mates with the adjusting stud 110 is rotatably provided on the frame 100. During actual adjustment, the extension length of the adjusting stud 110 can be adjusted simply by rotating the rotating nut, thereby adjusting the tension of the corresponding first belt 230. Furthermore, a rotating bearing is provided on the mounting head 120 to accommodate the mounting of the rotating shaft 220.

[0038] 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.

[0039] 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 surface of the stacking platform of the external stacking equipment A 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 surface of the stacking platform of the external stacking equipment A 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 external stacking equipment A 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 transport. During this process, the soft ceramic being transported on the second belt 340 is in a relatively stationary state with the stacking platform of the external stacking equipment A. Therefore, the newly laid soft ceramic will not slip on the stacking platform surface of the external stacking equipment A 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.

[0040] 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 external stacking equipment A. When the soft ceramic is on the first belt 230, the sliding frame 320 slides out relative to the frame 100 along the conveying direction of the soft ceramic and gradually enters the stacking equipment A. At this time, the output end of the drive mechanism 400 rotates, and the soft ceramic on the first belt 230 can be gradually transferred to the second belt 340 until the soft ceramic 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 ceramic can be directly and gradually laid flat on the stacking platform of the stacking equipment A. In the whole process, the soft ceramic 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 external stacking equipment A. The soft ceramic tile is then conveyed by the second belt 340 to its output end. 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 external stacking equipment A. 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.

[0041] It should be further explained 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 front end of the flexible ceramic tile is already in contact with the limiting structure on the stacking platform of the external stacking equipment A 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 at the bottom during the fall, resulting in scratches and wear.

[0042] 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 external stacking equipment A 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 external stacking equipment A 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 point, the outward end of the soft ceramic is flush with the corresponding side of the stacking platform of the external stacking equipment A, rather than the corresponding end of the second belt 340 being flush with the corresponding side of the stacking platform of the external stacking equipment A. When the outward end of the flexible ceramic is aligned with the side of the stacking platform of the external stacking equipment A, the telescopic actuator 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 external stacking equipment A or on the flexible ceramic that has already been stacked in place.

[0043] 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.

[0044] Finally, it should be noted that the sliding frame 320 is also equipped with a structure similar to the adjusting stud 110, mainly to facilitate the adjustment of the tension of the second belt 340.

[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 external stacking equipment A 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] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
