Description

[0002] At present, soft porcelain needs to be stacked and transferred during the processing procedures such as molding, drying, edge grinding, and warehousing. Since soft porcelain has the same softness as rubber, which is different from the hard texture of traditional ceramics, it cannot be stacked in the conventional plate-like manner during the transfer process, such as the continuous stacking method in the CN109095191A-automatic stacking machine. If such a stacking method is used, it is easy to cause scratches on the surface of the soft porcelain, affecting the quality of production. For this reason, the current unloading and stacking of soft porcelain is basically carried out by using a traditional multi-degree-of-freedom manipulator through suction cup adsorption. Although this unloading and stacking method can realize the unloading of soft porcelain one by one and protect the soft porcelain, the overall equipment cost is high, the control system requirements are high, and the efficiency of unloading and stacking is low.

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] See also Figures 1 to 7The present application provides a soft porcelain stacking device, comprising a frame 100, a horizontal conveying mechanism 200, a telescopic conveying mechanism 300, a driving mechanism 400, a universal telescopic transmission mechanism 500 and a lifting stacking mechanism 600; the horizontal conveying mechanism 200 is mounted on the frame 100; the telescopic conveying mechanism 300 can be 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 driving mechanism 400 is mounted on the frame 100 and outputs The 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 driving 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 transported thereon on the receiving end of the lifting and stacking mechanism 600.

[0034] In the present application, the driving mechanism 400 can be a conventional servo motor, and its output end can be connected to the input end of the horizontal conveying mechanism 200 through a coupling. The horizontal conveying mechanism 200 can be a conventional belt conveying mechanism.

[0035] The soft porcelain unloading and stacking device is designed with a horizontal conveying mechanism 200 for receiving the soft porcelain delivered by the external conveying line, so as to adjust the conveying speed of the soft porcelain and adapt to the action of the telescopic conveying mechanism 300. The telescopic conveying mechanism 300 is designed to slide on the frame 100, so that the telescopic conveying mechanism 300 can extend into the lifting and stacking mechanism 600 after receiving the soft porcelain output by the horizontal conveying mechanism 200 to gradually lay the soft porcelain delivered thereon in the lifting and stacking mechanism 600; and gradually withdraw from the lifting and stacking mechanism 600 during the laying process. Such a design can not only solve the problem that the soft porcelain of the product is easily stacked when the transmission conveyor belt is conveying the soft porcelain, and the soft porcelain and the conveyor belt or stacking equipment rub against each other during the process of receiving the soft porcelain, thereby damaging the surface of the soft porcelain, but also can lay and stack the soft magnets flatly. The universal telescopic transmission mechanism 500 is designed to transmit the transmission, which is adapted to the transmission requirements of the telescopic conveying mechanism 300 that is constantly shifting. In addition, the universal telescopic transmission mechanism 500 can also achieve the effect of using one driving mechanism 400 to simultaneously drive the horizontal conveying mechanism 200 and the telescopic conveying mechanism 300, thereby reducing the equipment cost. The lifting and stacking mechanism 600 in this application can be a conventional

[0036] See also Figure 1 to Figure 2In one embodiment of the present application, in order to facilitate the reception of soft porcelain transported by external equipment, such as soft porcelain transported by drying equipment, molding equipment, etc., the horizontal conveying mechanism 200 includes two rotating shafts 220 rotatably mounted on the frame 100 and a plurality of first belts 230 wound around the two rotating shafts 220, and the rotating shaft 220 at one end of the output direction is located between two adjacent first belts 230 and is rotatably mounted with a rotating wheel 210; one end of any of the rotating shafts 220 is connected to the output end of the driving mechanism 400, and a plurality of second belts 340 are rotatably mounted on the telescopic conveying mechanism 300, and the upper portions of all the second belts 340 respectively bypass the corresponding rotating wheels 210; the soft porcelain transported on the first belt 230 can be smoothly received by the second belt 340 and driven forward for transportation.

[0037] Among them, the second belt 340 is arranged on the telescopic conveying mechanism 300 and bypasses the corresponding rotating wheel 210. Such a design enables the input end of the telescopic conveying mechanism 300 to be directly connected to the output end of the first belt 230, and there is no gap between the two, which is conducive to the smooth transfer of the soft porcelain from the first belt 230 to the second belt 340. In actual use, in order to avoid the slippage between the soft porcelain and the first belt 230 or the second belt 340 due to the speed difference between the first belt 230 and the second belt 340, in this application, the telescopic conveying mechanism 300 and the horizontal conveying mechanism 200 are designed to run synchronously, that is, in the actual installation process, in addition to being directly connected to any rotating shaft 220, the output end of the driving mechanism 400 is connected to the input end of the telescopic conveying mechanism 300 through the universal telescopic transmission mechanism 500, and the rotating shaft 220 and the telescopic conveying mechanism 300 are synchronously rotated through the universal telescopic transmission mechanism 500, so that the first belt 230 and the second belt 340 are both synchronously moved, and both have the same conveying speed.

[0038] In addition, the rotating wheel 210 and the corresponding rotating shaft 220 can rotate relative to each other. Such a design allows the telescopic conveying mechanism 300 to automatically adapt to the movement of the telescopic conveying mechanism 300 through the relative sliding movement between the second belt 340 and the rotating wheel 210 when extending forward.

[0039] See also Figure 3 and Figure 4In the above-mentioned 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 drive 310, a sliding frame 320 and a driving shaft 330 that can be rotatably installed on both ends of the sliding frame 320. The second belt 340 is provided with a plurality of belts and is respectively wound around the two driving shafts 330. The sliding frame 320 can be slidably installed on the frame 100 along the conveying direction of the horizontal conveying mechanism 200. The telescopic drive 310 is installed on the frame 100 and the output end is connected to the corresponding end of the sliding frame 320. All the upper areas of the second belts 340 located between the two driving shafts 330 bypass the corresponding rotating wheels 210, and one end of any driving shaft 330 is connected to the output end of the universal telescopic transmission mechanism 500.

[0040] Among them, the second belt 340 is a triangular structure design when viewed from the side, that is, the two drive shafts 330 form two corners of the bottom surface, and the rotating wheel 210 is the vertex of the triangle. Specifically, in the present application, the sliding frame 320 can be displaced relative to the horizontal conveying mechanism 200, that is, in the actual use process, the two drive shafts 330 can be displaced relative to the rotating wheel 210. After the sliding frame 320 slides and extends relative to the frame 100 along the conveying direction of the soft porcelain, the second belt 340 will drive the rotating wheel 210 and the rotating shaft 220 to rotate relative to each other. 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. On the contrary, when the sliding frame 320 slides back and retracts into the frame 100 along the opposite direction of the conveying of the soft porcelain, with the sliding frame 320 as the observation reference, the rotating wheel 210 will move in the direction of the conveying direction. In fact, since the second belt 340 is designed to be triangular when viewed from the side, when the soft porcelain is transported on the second belt 340, the soft porcelain 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 conducive to the downward end of the soft porcelain first contacting the stacking platform surface of the lifting and stacking mechanism 600 or the upper surface of the already stacked soft porcelain after extending out of the second belt 340. Since the second belt 340 continues to transport the soft porcelain at this time, and the sliding frame 320 retreats at the same time, the soft porcelain being transported at this time is due to its own weight and its own flexibility. The soft porcelain is gradually spread out on the stacking platform surface of the lifting and stacking mechanism 600 or the upper surface of the stacked soft porcelain. The retracting action of the sliding frame 320 offsets the inertial force exerted by the second belt 340 on the soft porcelain during transportation. In this process, the soft porcelain being transported 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 spread soft porcelain will not slip with the stacking platform surface of the lifting and stacking mechanism 600 or the upper surface of the stacked soft porcelain, avoiding scratches. At the same time, the soft porcelain is stacked in a flat manner, and the overall stacking quality is good.

[0041] In addition, in the above embodiment, 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 stays on the first belt 230, after the sliding frame 320 slides out relative to the frame 100 along the conveying direction of the soft porcelain and gradually enters into the lifting and stacking mechanism 600 and takes position, the output end of the driving 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 feedback can be detected according to the sensor installed on the end of the sliding frame 320, and then the telescopic driver 310 can be controlled 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 spread on the stacking platform of the lifting and stacking mechanism 600. During the whole process, the soft porcelain and the stacking platform, or the second belt 340, will not actually produce excessive slippage, thereby largely eliminating the occurrence of scratches. After the soft porcelain completely stays on the second belt 340, after 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, the soft porcelain is conveyed to the output end by the second belt 340. At this time, the sensor installed on the end of the sliding frame 320 can be used to detect feedback, and then the telescopic driver 310 can be controlled 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. Therefore, in fact, whether the soft porcelain stays on the first belt 230 or the second belt 340, the above functions can be realized, and the soft porcelain will not be scratched due to relative displacement of the soft porcelain relative to the first belt 230 or the second belt 340 during the conveying process.

[0042] It should be noted that, in actual use, the length of the soft porcelain should be smaller than the length of the first belt 230 and the second belt 340, which is the key to avoid the relative displacement of the soft porcelain relative to the first belt 230 or the second belt 340 during the conveying process. In this embodiment, during the process of the second belt 340 conveying forward and the sliding frame 320 gradually retracting, since the front end of the soft porcelain has contacted with the limiting structure on the stacking platform of the lifting stacking mechanism 600 or the uppermost soft porcelain that has been stacked in place, the soft porcelain will not continue to move forward due to inertia during the entire conveying process, nor will it be like the plate in the patent CN109095191A-automatic plate stacking machine, after being output from the conveyor belt, it will be received by the temporary plate receiving device, and the plate will slip relative to the temporary plate receiving device during this process. It will not be intercepted by the traditional way of intercepting directly at the front end of the conveyor belt through the limiting baffle, so that the plate will slip relative to the receiving end at the bottom during the falling process and cause scratches and wear.

[0043] Further, in the above-mentioned improved embodiment, in order to make the soft porcelain on the second belt 340 contact the stacking platform of the lifting stacking mechanism 600 or the soft porcelain already stacked in place more quickly after being output, the ratio between the radius of the second belt 340 bypassing the drive shaft 330 at one end of its output direction and the thickness of the soft porcelain is less than 6:1. The main purpose of such a design is to reduce the relative height between the output soft porcelain and the stacking platform of the lifting stacking mechanism 600 or the soft porcelain already stacked in place, which is conducive to reducing the deviation of the newly stacked soft porcelain falling on the stacking platform or the soft porcelain already stacked in place, and ensuring the stacking effect. In the actual stacking process, the soft porcelain on the second belt 340 needs to extend one end of the second belt 340 corresponding to the end of the second belt 340, and then the end of the soft porcelain facing outward is flush with the side corresponding to the stacking platform of the lifting stacking mechanism 600, rather than the end of the second belt 340 corresponding to the end of the second belt 340 is flush with the side corresponding to the stacking platform of the lifting stacking mechanism 600. When the outward end of the soft porcelain is flush with the side corresponding to the stacking platform of the lifting and stacking mechanism 600, the telescopic driver 310 has controlled the sliding frame 320 to gradually retract, so that the soft porcelain's own deflection is utilized to make its extended end gradually stacked on the stacking platform of the lifting and stacking mechanism 600 or the soft porcelain that has been stacked in place.

[0044] Furthermore, in fact, in actual production applications, the second belt 340 is basically not directly installed on the driving shaft 330, and generally the second belt 340 is wound on a reel of the driving shaft 330. Specifically, a plurality of second reels 350 are provided on the two driving shafts 330, and all the second belts 340 are respectively and parallelly wound on the second reels 350 corresponding to the two driving shafts 330, and the ratio between the diameter of the second reel 350 located at one end of the second belt 340 in the output direction and the thickness of the soft porcelain is less than 5:1.

[0045] See also Figure 5 In the above-mentioned improved embodiment, in order to reduce the overhang between the outward end of the soft porcelain and the stacking platform of the lifting stacking mechanism 600 or the upper surface of the soft porcelain already stacked after the soft porcelain is output from the second belt 340, the overhang easily causes the newly stacked soft porcelain to be inaccurately positioned. Therefore, in an improved embodiment of the present application, the sliding frame 320 is provided with a plurality of discharge wedge blocks 360 at one end located in the output direction of the second belt 340, and each of the discharge wedge blocks 360 is rotatably mounted with rollers 370, and the outer circumference of the rollers 370 penetrates and extends out of both sides of the discharge wedge blocks 360. The rollers 370 are provided mainly to prevent the discharge wedge blocks 360 from being scratched by relative friction with the soft porcelain already stacked and the newly transported soft porcelain.

[0046] See also Figure 1 and Figure 6 In order to realize the synchronous rotation of the driving shaft 330 and the rotating shaft 220 and change the transmission direction at the same time, in one embodiment of the present 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 can be telescopic along its axial direction. The other end of any universal joint 520 is connected to the output end of the driving 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 implementation, the axial direction of the driving mechanism 400 is parallel to the axial directions of the driving shaft 330 and the rotating shaft 220. At this time, in order to allow the telescopic shaft 510 to have sufficient installation space and the installation space required for transmission, the connection between the output end of the driving mechanism 400 and the rotating shaft 220 needs to be relatively far away, so that the corresponding universal joint 520 can be directly connected to the corresponding end of the driving 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 through a belt, so that a compact installation can be achieved.

[0048] In another embodiment of the present application, in order to facilitate compact installation, the two universal joints 520 are connected to a steering gear 530 at one end facing outward, and the two steering gears 530 are respectively connected to the input end of the telescopic conveying mechanism 300 and the output end of the driving mechanism 400. Through the design of the steering gear 530, the output end of the driving mechanism 400 can be directly connected to the rotating shaft 220 at a short distance and can also transmit to the driving shaft 330. Through the two steering gears 530, two steering transmissions are performed. Such a design enables the driving mechanism 400 to rotate synchronously through the telescopic shaft 510 and the universal joints at both ends while directly driving the rotating shaft 220 to rotate, thereby ensuring the compactness of the structure. It should be noted that the steering gear is a conventional structure, and its interior is a pair of mutually meshing bevel gears, so that 90° steering can be achieved, which is not described in detail in this application.

[0049] See also Figure 6 It should be noted that, when the telescopic drive 310 drives 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 the present application, the telescopic shaft 510 includes a main rod 511 and a secondary cylinder rod 512, one end of the secondary cylinder rod 512 is sleeved on one end of the main rod 511, and the secondary cylinder rod 512 and the main rod 511 are connected to the universal joint 520 at their outward ends; a convex ridge 513 is axially arranged on the outer wall of the end of the main rod 511 that cooperates with the secondary cylinder rod 512, and a sliding groove that cooperates with the convex ridge 513 is arranged on the secondary cylinder rod 512. In this embodiment, when the telescopic drive 310 drives the sliding frame 320 to extend out of the frame 100, since the driving mechanism 400 is fixedly installed on the frame 100, in order to realize the transmission between the driving mechanism 400 and the driving shaft 330, the main rod 511 and the secondary barrel rod 512 move in opposite directions along their respective axial directions, and the entire telescopic shaft 510 becomes longer. When the telescopic drive 310 drives the sliding frame 320 and the frame 100 to retract, the main rod 511 and the secondary barrel rod 512 move in opposite directions along their respective axial directions, and the entire telescopic shaft 510 becomes shorter. However, whether the telescopic shaft 510 becomes longer or shorter, due to the matching structure of the convex rib 513 and the slide groove, the two can only move in the axial direction, and when rotating around their own axis, the two rotate synchronously.

[0050] See also Figure 7In one embodiment of the present application, the lifting and stacking mechanism 600 includes a bracket 610, a lifting platform 620 and a lifting assembly arranged on the bracket 610. The lifting platform 620 is installed on the lifting end of the lifting assembly. A carrying conveyor belt 640 is rotatably installed on the lifting platform 620. The bracket 610 is located on one side of the lifting platform 620 and a conveyor belt 630 is arranged. 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 convey the stacked soft porcelain stack to the conveyor belt 630.

[0051] Among them, the lifting platform 620 is a regular platform structure. In the actual stacking process, in order to enable the lifting platform 620 to place the stacked soft porcelain stack on the carrying conveyor belt 640 in the later stage, a limit baffle is also provided on one side of the lifting platform 620. In the actual use process, each time a piece of soft porcelain is stacked, the lifting assembly drives the lifting platform 620 to descend by the thickness of a piece of soft porcelain. Such a design ensures that the height difference between the soft porcelain transported by the second belt 340 and the soft porcelain stacked on the carrying conveyor belt 640 remains fixed each time, which is conducive to controlling the stacking quality and reducing the risk of scratching the soft porcelain. The carrying conveyor belt 640 is connected to the conveying motor 650 through a chain or a belt. Similarly, the conveying belt 630 is also connected to the external delivery motor 660 through a chain or a belt, wherein the conveying motor 650 is installed on the lifting platform 620, and the external delivery motor 660 is installed on the bracket 610.

[0052] It should be noted that the lifting assembly is a conventional screw motor structure, that is, a lifting motor is provided on the bracket 610, the lifting motor drives the nut on the bracket 610 to rotate, a screw is installed in the nut, and the upper end of the screw is connected to the back of the lifting platform 620, such a structural design can achieve precise lifting.
