Description

Technical Field

[0001] The invention belongs to the technical field of ceramic product manufacturing, and in particular relates to a transfer device for a plate embryo and a baking system containing the transfer device. Background Art

[0002] Ceramic materials are a type of inorganic non-metallic material made by forming and high-temperature sintering of natural or synthetic compounds. They have the advantages of high melting point, high hardness, high wear resistance, oxidation resistance, etc. Therefore, the demand for ceramic tableware made of ceramic materials as raw materials is increasing. It includes various products made of clay or a mixture containing clay through mixing, forming, and calcining. With the improvement of people's living standards, people's quality requirements for ceramic tableware increase. In order to improve the quality of ceramic tableware, it is particularly important to improve the calcination process. However, the existing technology has the phenomenon of uneven heating of ceramic tableware during the calcination process. Summary of the invention

[0003] Therefore, in order to overcome the above technical problems, the first object of the present invention is to provide a transfer device for a disk embryo, comprising a third conveyor belt, a turning device, a twisting device and a controller;

[0004] The flipping device includes a first horizontal driving mechanism, a first rotating driving mechanism, a plurality of first extracting mechanisms and a plurality of fixing mechanisms, wherein the plurality of first extracting mechanisms are connected to the output end of the first horizontal driving mechanism, the plurality of first extracting mechanisms can move side by side with the first horizontal driving mechanism, the plurality of fixing mechanisms are connected to the output end of the first rotating driving mechanism, the first extracting mechanism is used to extract workpieces on a certain working surface, the first horizontal driving mechanism can drive the first extracting mechanism to the top of the fixing surface of the fixing mechanism, the plurality of fixing mechanisms are arranged side by side, the fixing surfaces of the plurality of fixing mechanisms are located on the same plane, the fixing mechanism can complete flipping along the rotation of the output end of the first rotating driving mechanism, and the rotating axis of the output end of the first rotating driving mechanism is perpendicular to the conveying direction of the third conveyor belt and parallel to the horizontal plane;

[0005] The twisting device includes a second horizontal driving mechanism and a plurality of second extracting mechanisms, the plurality of second extracting mechanisms are connected to the output end of the second horizontal driving mechanism and can move side by side, the second extracting mechanism includes a second rotating driving mechanism and a plurality of second vertical driving mechanisms, the second vertical driving mechanism is connected to the output end of the second rotating driving mechanism through a connecting frame, a second suction cup is provided at the output end of the lower end of the second vertical driving mechanism, the second horizontal driving mechanism can drive the second extracting mechanism to move in a horizontal direction perpendicular to the conveying direction of the third conveyor belt, and the rotating axis of the output end of the second rotating driving mechanism is perpendicular to the horizontal plane;

[0006] The controller is electrically connected to the first horizontal driving mechanism, the first extracting mechanism, the first rotating driving mechanism, the fixing mechanism, the second horizontal driving mechanism, the second vertical driving mechanism, the second rotating driving mechanism and the second suction cup.

[0007] Furthermore, the first extraction mechanism includes a first vertical drive mechanism and a first suction cup, the first vertical drive mechanism is connected to the output end of the first horizontal drive mechanism, the first suction cup is connected to the output end of the first vertical drive mechanism, and the first vertical drive mechanism and the first suction cup are electrically connected to the controller. The first vertical drive mechanism can drive the first suction cup to move up and down to extract the disc embryo on the working plane, and the first suction cup can directly act on the surface of the flipped object without clamping the flipped object. In particular, ceramic products in the production process are relatively fragile. If a clamping fixture is used as an extraction mechanism to fix the side of the ceramic product, the clamping force is likely to cause damage to the ceramic product.

[0008] Furthermore, the fixing mechanism includes a connecting rod and a third suction cup, one end of the connecting rod is connected to the side of the output end of the first rotation drive mechanism, the third suction cup is connected to the other end of the connecting rod, and the third suction cup is electrically connected to the controller. If the third suction cup is directly connected to the side of the output end of the first rotary drive mechanism, the output end of the first rotary drive mechanism needs to be located directly above the placed plane so that the third suction cup can rotate to make the flipped disc embryo reach above the placed plane. In order for the flipped disc embryo to be smoothly flipped 180°, the flipped disc embryo must be suspended above the third conveyor belt. Directly dropping the disc embryo may cause damage to the object. Connecting the third suction cup to the side of the output end of the first rotary drive mechanism through a connecting rod allows the output end of the first rotary drive mechanism to be set on the side of the third conveyor belt. Such a setting allows the flipped object to directly reach the upper surface of the third conveyor belt after the output end of the first rotary drive mechanism rotates, and the third suction cup can directly act on the surface of the flipped disc embryo without clamping the flipped object. In particular, ceramic products in the production process are relatively fragile. If a clamping fixture is used as a fixing mechanism to fix the side of the ceramic product, the clamping force can easily cause damage to the ceramic product.

[0009] Furthermore, the connecting rod is a C-shaped structure, and the opening of the C-shaped structure faces the direction of rotation. When a heavier flipped object needs to be extracted, it is usually necessary to replace the second suction mechanism with a stronger suction force. The suction cup with a stronger suction force is usually larger in size and higher in height. By setting the connecting rod as a C-shaped structure, the height of the blank when extracted by the third suction cup remains unchanged, and the vertical length of the end of the C-shaped mechanism connected to the third suction cup can be changed to accommodate the third suction cups of different heights.

[0010] Furthermore, it also includes a sensor and an alarm, wherein the detection end of the sensor is located at the connection position between the first extraction mechanism and the fixing mechanism, the output end of the sensor is connected to the input end of the controller, and the output end of the controller is connected to the alarm. The sensor can be a photoelectric sensor of the prior art, and when the first extraction mechanism fails to extract the disc embryo, after the first extraction mechanism reaches the connection position with the fixing mechanism, the sensor does not sense that there is an overturned object within the detection end range, and transmits this signal to the controller, and the controller controls the alarm to work.

[0011] The first objective of the present invention provides a transfer device for a disk blank, which has the following beneficial effects: (1) In the turning device, the first horizontal driving mechanism of the turning device moves a plurality of first extraction mechanisms arranged side by side to the top of the disk blanks to be turned over with the same spacing and extracts them to a plurality of fixing mechanisms arranged side by side, and the first rotary driving mechanism enables the fixing mechanisms to complete the turning along the rotation of the output end of the first rotary driving mechanism and place the disk blanks on the third conveyor belt, so that the surface of the turned object that was originally facing upward faces downward after turning, and the turned disk blanks can move side by side along the third conveyor belt;

[0012] (2) In the twisting device, the second horizontal driving mechanism moves the plurality of second extraction mechanisms to the top of the third conveyor belt. The second extraction mechanism includes a second rotating driving mechanism that can drive the plurality of second vertical driving mechanisms connected to its output end to rotate, so that the plurality of second suction cups connected to the same second rotating driving mechanism can be respectively located directly above the plurality of disc embryos in the same row, thereby completing the suction of the disc embryos in the same row of the third conveyor belt. The plurality of second extraction mechanisms can work simultaneously to complete the suction of the plurality of rows of disc embryos on the third conveyor belt. The second rotating driving mechanism drives the plurality of second vertical driving mechanisms connected to its output end to rotate again, so that the disc embryos connected to the output ends of the plurality of second rotating driving mechanisms can be located in the same row, so that the disc embryos originally arranged in multiple rows are arranged in one row and transported to the next working platform or conveying device under the action of the second horizontal driving mechanism.

[0013] (3) In summary, the first objective of the present invention provides a transfer device for a plate embryo that can simultaneously turn over multiple plate embryos arranged on a plane at the same interval, so that the turned plate embryos move side by side with the third conveyor belt, and the twisting device can simultaneously extract multiple rows of plate embryos moving side by side and twist them into the same row, so that multiple rows of plate embryos turned over to the third conveyor belt at different times can be placed side by side on the next station, and the transfer device for the plate embryo is applied to the turning of the baking system, so that both sides of the plate embryo can be baked and heated more evenly.

[0014] The second object of the present invention is to provide a baking system, comprising a transfer device for disc embryos, a first conveyor belt, a second conveyor belt, a first oven and a second oven. The transfer device for disc embryos is the same as the transfer device for disc embryos provided by the first object of the present invention. The first conveyor belt runs through the input end and the output end of the first oven, and the second conveyor belt runs through the input end and the output end of the second oven. The conveying direction of the first conveyor belt is parallel to the conveying direction of the second conveyor belt, and the conveying direction of the first conveyor belt is perpendicular to the conveying direction of the third conveyor belt. The first horizontal driving mechanism can drive the first extraction mechanism to move above the first conveyor belt, and the second horizontal driving mechanism can drive the second extraction mechanism to move above the second conveyor belt.

[0015] The second purpose of the present invention provides a baking system with a transfer device, which has the beneficial effects that: the flipping device can flip a plurality of disc embryos that are successively output from the first oven along the first conveyor belt at the same time, so that the disc embryos that are flipped at the same time can move side by side with the third conveyor belt, and the twisting device can simultaneously extract and twist a plurality of rows of disc embryos moving side by side into the same row, so that a plurality of rows of disc embryos that are flipped to the third conveyor belt at different times can be placed side by side on the second conveyor belt, so that after the disc embryos that were originally output one by one from the first oven are flipped, they can enter the second oven with the second conveyor belt in the form of a plurality of disc embryos side by side for further baking, which is more efficient and realizes that the two sides of the disc embryos are baked in sequence, and the heating is more even.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0025] Embodiment 1:

[0026] Figure 1-Figure 5 The present invention shows a baking system, which includes a transfer device for a blank, a first conveyor belt 51, a second conveyor belt 61, a first oven 5 and a second oven 6. The first conveyor belt 51 runs through the input end and the output end of the first oven 5, and the second conveyor belt 61 runs through the input end and the output end of the second oven 6.

[0027] The transfer equipment for the disc embryo comprises a third conveyor belt 1, a turning device 2, a twisting device 3 and a controller; the turning device 2 comprises a first horizontal driving mechanism 21, a first rotating driving mechanism 23, two first extracting mechanisms 22 and two fixing mechanisms 24, the two first extracting mechanisms 22 are connected to the output end of the first horizontal driving mechanism 21, the two first extracting mechanisms 22 can move side by side with the first horizontal driving mechanism 21, the two fixing mechanisms 24 are connected to the output end of the first rotating driving mechanism 23, the first extracting mechanism 22 is used to extract the workpiece on a certain working surface, the first horizontal driving mechanism 21 can drive the first extracting mechanism 22 to the top of the fixing surface of the fixing mechanism 24, the two fixing mechanisms 24 are arranged side by side, the fixing surfaces of the two fixing mechanisms 24 are located on the same plane, the fixing mechanism 24 can complete the turning along the rotation of the output end of the first rotating driving mechanism 23, and the rotating axis of the output end of the first rotating driving mechanism 23 is perpendicular to the conveying direction of the third conveyor belt 1 and parallel to the horizontal plane;

[0028] The twisting device 3 includes a second horizontal driving mechanism 31 and two second extracting mechanisms 32. The two second extracting mechanisms 32 are connected to the output end of the second horizontal driving mechanism 31 and can move side by side. The second extracting mechanism 32 includes a second rotating driving mechanism 321 and two second vertical driving mechanisms 322. The second vertical driving mechanism 322 is connected to the output end of the second rotating driving mechanism 321 through a connecting frame 323. The output end of the lower end of the second vertical driving mechanism 322 is provided with a second suction cup 324. The second horizontal driving mechanism 31 can drive the second extracting mechanism 32 to move in a horizontal direction perpendicular to the conveying direction of the third conveyor belt 1. The rotation axis of the output end of the second rotating driving mechanism 321 is perpendicular to the horizontal plane.

[0029] The conveying direction of the first conveyor belt 51 is parallel to the conveying direction of the second conveyor belt 61, and the conveying direction of the first conveyor belt 51 is perpendicular to the conveying direction of the third conveyor belt 1. The first horizontal driving mechanism 21 can drive the first extraction mechanism 22 to move above the first conveyor belt 51, and the second horizontal driving mechanism 31 can drive the second extraction mechanism 32 to move above the second conveyor belt 61.

[0030] The controller is electrically connected to the first horizontal driving mechanism 21 , the first extracting mechanism 22 , the first rotating driving mechanism 23 , the fixing mechanism 24 , the second horizontal driving mechanism 31 , the second vertical driving mechanism 322 , the second rotating driving mechanism 321 and the second suction cup 324 .

[0031] The first extraction mechanism 22 includes a first vertical drive mechanism 221 and a first suction cup 222. The first vertical drive mechanism 221 is connected to the output end of the first horizontal drive mechanism 21, and the first suction cup 222 is connected to the output end of the first vertical drive mechanism 221. The first vertical drive mechanism 221 and the first suction cup 222 are electrically connected to the controller. The first vertical drive mechanism 221 can drive the first suction cup 222 to move up and down to extract the disc embryo 7 on the working plane. The first suction cup 222 can directly act on the surface of the flipped object without clamping the flipped object. In particular, ceramic products in the production process are relatively fragile. If a clamping fixture is used as an extraction mechanism to fix the side of the ceramic product, the clamping force is likely to cause damage to the ceramic product.

[0032] The fixing mechanism 24 includes a connecting rod 241 and a third suction cup 242. One end of the connecting rod 241 is connected to the side of the output end of the first rotary drive mechanism 23, and the third suction cup 242 is connected to the other end of the connecting rod 241. The third suction cup 242 is electrically connected to the controller. If the third suction cup 242 is directly connected to the side of the output end of the first rotary drive mechanism 23, the output end of the first rotary drive mechanism 23 needs to be located directly above the placement plane so that the third suction cup 242 can rotate to allow the flipped disc embryo 7 to reach the top of the placement plane. In order for the flipped disc embryo 7 to flip 180° smoothly, the flipped disc embryo 7 must be vacated above the third conveyor belt 1. Directly dropping the disc embryo 7 may cause damage to the object. The third suction cup 242 is connected to the first rotary drive mechanism 23 through the connecting rod 241. The side of the output end of the first rotating drive mechanism 23 can be arranged on the side of the third conveyor belt 1. This arrangement can make the flipped object directly reach the upper surface of the third conveyor belt 1 after the output end of the first rotating drive mechanism 23 rotates, and the third suction cup 242 can directly act on the surface of the flipped disc embryo 7 without clamping the flipped object. In particular, ceramic products in the production process are relatively fragile. If a clamping fixture is used as the fixing mechanism 24 to fix the side of the ceramic product, the clamping force will easily cause damage to the ceramic product.

[0033] The connecting rod 241 is a C-shaped structure, and the opening of the C-shaped structure faces the direction of rotation. When a heavier flipped object needs to be extracted, it is usually necessary to replace the second suction mechanism with a greater suction force. The suction cup with a greater suction force is usually larger in size and higher in height. The connecting rod 241 is set as a C-shaped structure. Under the condition that the height of the plate embryo 7 when being extracted by the third suction cup 242 remains unchanged, the vertical length of the end of the C-shaped mechanism connected to the third suction cup 242 can be changed to accommodate the third suction cup 242 of different heights.

[0034] The sensor also includes a sensor and an alarm. The detection end 4 of the sensor is located at the connection position between the first extraction mechanism 22 and the fixing mechanism 24. The output end of the sensor is connected to the input end of the controller, and the output end of the controller is connected to the alarm. The sensor can adopt a photoelectric sensor of the prior art. When the first extraction mechanism 22 fails to extract the disc embryo 7, after the first extraction mechanism 22 reaches the connection position with the fixing mechanism 24, the sensor does not sense that there is an overturned object within the detection end range. After transmitting this signal to the controller, the controller controls the alarm to work.

[0035] Working principle: Step (1): Multiple preformed discs 7 are successively output from the first oven 5 along the first conveyor belt 51. The first horizontal driving mechanism 21 drives two parallel first vertical driving mechanisms 221 to move to the top of the first conveyor belt 51. The two first vertical driving mechanisms 221 drive the first suction cups 222 connected to their output ends to descend and absorb the preformed discs 7 on the first conveyor belt 51. The first horizontal driving mechanism 21 drives the two first vertical driving mechanisms 221 to move together to the top of the third suction cup 242. The two first vertical driving mechanisms 221 drive the first suction cups 222 connected to their output ends to descend and absorb the preformed discs 7 on the first conveyor belt 51. The first suction cup 222 is lowered and placed on the action surface of the third suction cup 242. The first suction cup 222 is driven upward by the first vertical driving mechanism 221 and releases the disc embryo 7; step (2): the first rotary driving mechanism 23 simultaneously drives the two disc embryos 7 fixed to the two side-by-side third suction cups 242 and sucked by them to rotate 180° along the output end of the first rotary driving mechanism 23 as the axis. At this time, the disc embryo 7 can be placed on the upper surface of the third conveyor belt 1 after the third suction cup 242 is released, and the surface of the disc embryo 7 originally facing upward faces downward after being turned over; step (3): the two side-by-side disc embryos 7 moves along the third conveyor belt 1 to the bottom of the second extraction mechanism 32 close to the output end of the third conveyor belt 1. At the same time, the two side-by-side disc embryos 7 located in a row behind the two side-by-side disc embryos 7 move to the bottom of the second extraction mechanism 32 far from the output end of the third conveyor belt 1. The two second vertical driving mechanisms 322 respectively drive the two second extraction mechanisms 32 to descend and absorb the disc embryos 7 located below them. The four disc embryos 7 are simultaneously absorbed by the second suction cups 324 located above them. The two second vertical driving mechanisms 322 respectively drive the two second extraction mechanisms 32 to ascend. The four disc embryos 7 are 7 is extracted; step (4): the second horizontal driving mechanism 31 drives the two side-by-side second vertical driving mechanisms 322 to move to the top of the second conveyor belt 61, and the two vertical driving mechanisms are driven by the second rotating driving mechanism 321 and rotate 90 degrees along the output end of the second rotating driving mechanism 321 as the rotating axis. At this time, the four suction cups are side by side, and the second suction cup 324 connected to the output end of the second vertical driving mechanism 322 is driven downward by the second vertical driving mechanism 322. The four disc embryos 7 are placed on the upper end of the second conveyor belt 61 and enter the second oven 6 side by side with the second conveyor belt 61.

For ordinary technicians in the technical field to which the present invention belongs, simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
