Description

Technical Field

[0001] This utility model relates to the technical field of automatic tile blank loading equipment, specifically to an automatic tile blank loading machine. Background Technology

[0002] Tiles are a common building material in modern construction, primarily made from fired clay. During tile production, newly made tile blanks, due to their high moisture content, need to be placed in a cool, ventilated place to dry before firing. Currently, tile blank production is mechanized and automated. The blanks are placed directly on a conveyor belt, then manually removed and placed on material racks for transfer and air drying. Because of the high speed of the conveyor belt and the weight of the tile blanks, this process is physically demanding and labor-intensive, resulting in high labor costs and significantly increasing production costs. Furthermore, existing material racks vary in size, and the top, bottom, and middle trays are arranged differently, making mechanization and automation difficult. Additionally, the high production cost of these material racks means that a company with at least a thousand racks would need to spend at least several million yuan to upgrade them. Therefore, an automated tile blank loading system that can meet the requirements of existing material racks is needed. The existing material rack has two trays on each layer. The position and spacing of the trays on the material rack are inaccurate, making it difficult to automatically load the tile blanks onto the trays. Utility Model Content

[0003] The purpose of this invention is to provide an automatic tile blank loading machine, which overcomes the shortcomings of the existing technology.

The conveying device, the left positioning device, and the lifting device are connected to the control system. The position sensor is connected to the control system and is located at the material rack conveying mechanism in front of the lifting device.

[0012] Furthermore, the material rack conveying mechanism also includes a front positioning mechanism and a rear positioning mechanism located outside the lifting device. The front positioning mechanism and the rear positioning mechanism are used to fix the position of the material rack on the upper track. The front positioning mechanism and the rear positioning mechanism can move towards the front end and the rear end of the material rack. The front positioning mechanism and the rear positioning mechanism are each provided with a telescopic mechanism facing to the right. After the two telescopic mechanisms extend, they can cooperate with the front end and the rear end of the material rack.

[0015] Furthermore, the support frame is located on the right side of the material rack conveying mechanism, and the support frame is correspondingly arranged with the lowest loading tray of the material rack. The support frame can push the loading tray on it back to the material rack.

[0016] Furthermore, the push-pull mechanism is located on the left side of the upper frame track. The push-pull mechanism includes a lifting device and a push-pull device. The push-pull device is mounted on the lifting device. The lifting device is used to control the rising and falling of the push-pull device. The push-pull device is used to remove and reposition the material tray above the bottommost tray of the material rack, so that the tile blank transfer mechanism can transfer the tile blank to the tray. The lifting device and the push-pull device are connected to the control system. The front end of the push-pull device is also equipped with a photoelectric sensor that is connected to the control system signal.

[0017] Furthermore, the tile blank transfer mechanism includes a sliding device, a displacement device, and a picking device. The sliding device is installed above the push-pull mechanism, and the displacement device is installed on the sliding device. The picking device is installed on the displacement device.

[0019] Compared with the prior art, the implementation effect of this utility model is as follows: This automatic tile blank loading machine can position and fix the material rack. The left positioning device, lifting device, front positioning mechanism and rear positioning mechanism can position and fix the material rack, so that tile blanks can be loaded onto material racks with different sizes. At the same time, the push-pull mechanism can move the carrying tray on the material rack out and retrieve it. Under the action of the tile blank transfer mechanism, the tile blank is placed on the material rack. After the tile blank is placed, the material rack can be moved out from the material rack conveying mechanism, realizing fully automatic loading of tile blanks, saving a lot of manpower, and improving the working efficiency of tile blank loading.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The automatic tile blank feeding machine of this utility model is applied to a material rack 100 with rollers at the bottom. The material rack 100 is equipped with a carrying tray. The carrying trays at the bottom and top of the material rack 100 are placed directly on the frame 101 of the material rack 100. Multiple corresponding support plates 102 are provided on the material rack 100 between the bottom and top carrying trays. The carrying trays are placed on the support plates 102. After the carrying trays are lifted upward and away from the support plates 102, they can be removed from the material rack 100.

[0036] like Figure 1-6 As shown, the automatic tile blank loading machine includes: a material rack conveying mechanism 1 for feeding the material rack 100 into and out of the loading machine; a support frame 3 for carrying and pushing back the lowest loading tray on the material rack 100; a push-pull mechanism 2 for pushing out and pulling back the loading tray on the material rack 100; a tile blank transfer mechanism 4 for transferring the tile blanks to be loaded onto the loading tray; and a control system for controlling the operation of the material rack conveying mechanism 1, the push-pull mechanism 2, the support frame 3, and the tile blank transfer mechanism 4.

[0037] The material rack conveying mechanism 1 includes an upper rack track, which is configured to cooperate with the rollers of the material rack 100. A conveying device 11 is mounted on the upper rack track. The conveying device 11 includes an upper conveying mechanism 112 and a lower conveying mechanism 111 that cooperate with each other. The upper conveying mechanism 112 is mounted above the upper rack track via a gantry frame. Guide rollers 110, which cooperate with the material rack, are rotatably mounted on the inner side of the gantry frame. The upper conveying mechanism 112 is used to convey the material rack 100 onto the upper rack track, and the lower conveying mechanism 111 is used to convey the material rack 100 on the upper rack track. The upper conveying mechanism 112 and the lower conveying mechanism 111 are respectively connected to the control system. The connection allows the material rack 100 to smoothly enter and exit the upper rack track under the transmission of the conveying device 11. The upper rack track is also equipped with a left positioning device 13, a lifting device 12 and a position sensor 16. The position sensor 16 is used to detect the position of the material rack 100 on the upper rack track. The left positioning device 13 and the lifting device 12 are used to lift and position the material rack 100. The conveying device 11, the left positioning device 13, and the lifting device 12 are connected to the control system. The position sensor 16 is connected to the control system signal and is located at the material rack conveying mechanism 1 in front of the lifting device 12.

[0038] The material rack conveying mechanism 1 also includes a front positioning mechanism 15 and a rear positioning mechanism 14 disposed outside the lifting device 12. The front positioning mechanism 15 and the rear positioning mechanism 14 are used to fix the position of the material rack 100 on the upper track. The front positioning mechanism 15 and the rear positioning mechanism 14 can move towards the front end and the rear end of the material rack 100, respectively. The front positioning mechanism 15 and the rear positioning mechanism 14 are each provided with a telescopic mechanism facing to the right. After the telescopic mechanism extends, it can realize the positioning, clamping and fixing of the material rack 100 with the movement of the front positioning mechanism 15 and the rear positioning mechanism 14.

[0039] When the automatic tile blank loading machine is running, the control system controls the material rack conveying mechanism 1 to run first, followed by the operation of the upper conveying mechanism 112 and the lower conveying mechanism 111. The upper conveying mechanism 112 pushes the top of the material rack 100 to send the front part of the material rack 100 into the upper rack track. When the lower part of the material rack 100 cooperates with the lower conveying mechanism 111, the lower conveying mechanism 111 continues to convey the material rack 100 forward. When the front end of the material rack 100 is detected by the position sensor 16, the upper conveying mechanism 112 and the lower conveying mechanism 111 stop working, the left positioning device 13 is activated, and the material rack 100 is pushed to the right to achieve positioning of the material rack 100 in the left and right directions. After positioning is completed, the left positioning device 13 is reset, the lifting device 12 lifts the material rack 100, and then the front positioning mechanism 15 and the rear positioning mechanism 14 work to position and clamp the front and rear sides of the material rack 100 through the telescopic mechanism.

[0040] Since the top tray of the material rack 100 cannot be moved out by the push-pull mechanism 2, the bottom tray can only be pushed out of the material rack 100 by the push-pull mechanism 2. A support frame 3 is also provided on the right side of the material rack conveying mechanism 1. The support frame 3 is set in correspondence with the bottom tray of the material rack 100. When the bottom tray of the material rack 100 is pushed into the support frame 3 by the push-pull mechanism 2, the support frame 3 can push the tray on it back into the material rack 100.

[0041] A push-pull mechanism 2 is provided on the left side of the upper track. The push-pull mechanism 2 includes a lifting device 21 and a push-pull device 22. The push-pull device 22 is installed on the lifting device 21. The lifting device 21 is used to control the rising and falling of the push-pull device 22. The push-pull device 22 is used to remove and reposition the load pan above the bottom load pan of the material rack 100, so that the tile blank transfer mechanism 4 can transfer the tile blanks onto the load pan. The lifting device 21 and the push-pull device 22 are connected to the control system. The push-pull device 22 includes at least two telescopic sections. The first telescopic section can extend below the load pan, and the second telescopic section can lift the load pan after it has been lifted. The first telescopic section continues to push forward, causing the tray to move out of the material rack 100; the front end of the push-pull device 22 is also equipped with a photoelectric sensor 23 connected to the control system signal. The photoelectric sensor 23 is used to detect the position of the tray on the material rack 100 and send the position information to the control system. The control system controls the lifting device 21 to descend according to the position information, so that the push-pull device 22 moves to the bottom of the corresponding tray. Then the first telescopic section of the push-pull device 22 extends. After the extension is completed, the lifting device 21 drives the push-pull device 22 to rise, so that the tray is separated from the support frame 3. Then the second telescopic section of the push-pull device 22 extends, so that the tray is pushed out of the material rack 100.

[0042] A tile blank transfer mechanism 4 is provided above the push-pull mechanism 2. The tile blank transfer mechanism 4 includes a sliding device 41, a displacement device 42 and a material picking device 43. The sliding device 41, the displacement device 42 and the material picking device 43 are then controlled and connected to the control system. A sliding device 41 is installed above the push-pull mechanism 2. A displacement device 42 is installed on the sliding device 41, and a material picking device 43 is installed on the displacement device 42. The displacement device 42 is used to control the lifting and lowering of the material picking device 43. The material picking device 43 is used to pick up and put down tile blanks. The material picking device 43 includes a suction cup frame 431 with several suction cups. Two positioning devices are installed on the suction cup frame through the lifting mechanism 432. The positioning devices include an outer positioning mechanism and an inner positioning mechanism. The outer positioning mechanism can position the outer edges of the two loading trays, and the inner positioning mechanism can position the inner distance between the two loading trays. The lifting mechanism 432, the outer positioning mechanism 434, and the inner positioning mechanism 433 are respectively connected to the control system. A contact sensor 435 electrically connected to the control system is provided on the suction cup frame 431. The sliding device 41 is used to drive the displacement device 42 to move left and right, thereby realizing the movement of the production line 20. 1. The tile blanks to be loaded onto the shelf are transferred to the carrying tray. The left and right movement distance of the sliding device 41 is controlled by a preset control program in the control system. When the picking device 43 picks up the tile blanks from the production line 201 according to the preset program, the control system controls the lifting mechanism to work, so that the outer positioning mechanism 434 and the inner positioning mechanism 433 move upward to avoid the positioning device from contacting the production line when the suction cup picks up the tile blanks. When the contact sensor 435 contacts the production line, the contact sensor receives the first contact signal, and the control system controls the suction cup to continue to descend to a preset height (generally set at 5mm-10mm, the specific height can be adjusted according to production needs). Then the suction cup picks up the tile blanks (the suction cup is connected to a vacuum device, and the air circuit of the vacuum device is equipped with a solenoid valve connected to the control system. The control system controls the opening and closing of the air circuit through the solenoid valve, thereby realizing the suction cup's picking up and unloading), completing the picking up.Then, the control system controls the sliding device and the displacement device to transfer the picking device and the tile blanks on it to the top of the carrying tray. Then, the displacement device 42 controls the picking device 43 to descend. When the contact sensor on the picking device 43 contacts the carrying tray, the contact sensor obtains a second contact signal. The control system controls the lifting mechanism 432 to move the positioning device down. Then, the two claws of the outer positioning mechanism move inward and towards each other to bring the two carrying trays together. The two claws of the inner positioning mechanism move away from each other, so that the two carrying trays move away from each other, realizing the distance positioning of the two carrying trays. After the positioning is completed, the control system controls the outer positioning mechanism 434 and the inner positioning mechanism 433 to reset, and at the same time controls the lifting mechanism to reset. Then, the control system controls the displacement 42 to make the picking device continue to descend to a preset height (generally set at 5mm-10mm, the specific height can be adjusted according to production needs). Then, the control system controls the suction cup to put down the tile blanks. The tile blanks are placed on the carrying trays. Then, the picking device 43 returns to the production line 201 according to the preset program to pick up the tile blanks for the next placement.

[0043] The following is a detailed description of the operating steps of the automatic tile blank loading machine of this utility model:

[0044] The first step is to convey and position the material rack 100. The control system controls the material rack conveying mechanism 1 to run first, and the upper conveying mechanism 112 and the lower conveying mechanism 111 run. The upper conveying mechanism 112 pushes the top of the material rack 100 to send the front part of the material rack 100 into the upper rack track. When the lower part of the material rack 100 cooperates with the lower conveying mechanism 111, the lower conveying mechanism 111 continues to convey the material rack 100 forward. When the front end of the material rack 100 is detected by the position sensor 16, the upper conveying mechanism 112 and the lower conveying mechanism 111 stop working, the left positioning device 13 starts, and pushes the material rack 100 to the right to achieve positioning of the material rack 100 in the left and right directions. After positioning is completed, the left positioning device 13 resets, the lifting device 12 lifts the material rack 100, and then the front positioning mechanism 15 and the rear positioning mechanism 14 work to position and clamp the front and rear sides of the material rack 100.

[0045] The second step is to load the tile blanks onto the top tray. After the material rack 100 is conveyed and positioned, the push-pull device 22 of the push-pull mechanism 2, driven by the lifting device 21, detects the top of the material rack 100 through the photoelectric sensor 23. After detecting the top tray (i.e., the first detection of the tray), the control system controls the tile blank transfer mechanism 4 to work, and transfers the tile blanks 200 to the top tray of the material rack 100 through the picking device 43. Then, the control system controls the tile blank transfer mechanism 4 to reset.

[0046] The third step involves loading the tile blanks onto the central tray. During the resetting process of the tile blank transfer mechanism 4, the control system simultaneously controls the lifting device 21 to lower the push-pull device 22. During this downward movement, after the photoelectric sensor 23 detects the tray again, the lifting device 21 stops descending. Then, the control system controls the lifting device 21 to continue descending to a preset height (so that the push-pull device 22 can just enter below the detected tray and be above the tray below it). Next, the first extension section of the push-pull device 22 extends below the corresponding tray. After the first extension section extends, the lifting device... 21 drives the push-pull device 22 to rise to the pre-examination height, so that the corresponding loading tray is separated from the support plate 102 and does not contact the loading tray above. Then the second telescopic section of the push-pull device 22 extends, so that the loading tray is pushed out of the material rack 100. After the second telescopic section extends, the loading tray on the first telescopic section is also located in the space above the support rack 3. Then the control system controls the tile blank transfer mechanism 4 to work, and transfers the tile blank to the removed loading tray through the material picking device 43. Then the tile blank transfer mechanism 4 resets again, and the push-pull mechanism 2 performs the above operation again until the bottom loading tray is no longer operated.

[0047] The fourth step involves placing the tile blanks onto the bottom tray. As the lifting device 21 continues to descend, the photoelectric sensor 23 consistently detects the tray signal (caused by the obstruction formed by the bottom tray and the material rack 100 frame 101), and the descent height of the lifting device 21 reaches the lowest position reached in the first step of positioning. At this point, the control system controls the lifting device 21 to rise a preset distance from the bottom positioning position (this distance is greater than the thickness of the bottom frame 101 of the material rack 100), aligning the first telescopic section with the bottom tray. Then, the first telescopic section of the push-pull device 22 pushes the tray onto the support frame 3, and then the... One telescopic section retracts; at this time, the control system controls the tile blank transfer mechanism 4 to work, and the tile blank is transferred to the loading tray on the support frame 3 through the material picking device 43; then the tile blank transfer mechanism 4 resets; during the reset process of the tile blank transfer mechanism 4, the control system controls the front positioning mechanism 15, the rear positioning mechanism 14 and the lifting device 12 to reset, and the material rack 100 containing the tile blank falls back onto the upper frame track. At the same time, the material rack conveying mechanism 1 works, and the material rack 100 loaded with the tile blank is sent out of the upper frame track. The new material rack 100 to be loaded is conveyed to the upper frame track. This cycle is repeated to realize the automatic loading of the tile blank. During the process of the material rack 100 loaded with tile blanks being sent out of the upper rack track, the position sensor 16 is always blocked. When the blocking signal of the position sensor 16 disappears, that is, the material rack 100 loaded with tile blanks is sent out of the upper rack track; and after a new material rack 100 to be loaded enters the upper rack track, the position sensor 16 will be blocked again, and then the above steps will be performed.

[0048] Furthermore, it should be noted that the device of this utility model can also be used in pairs, as shown in the attached diagram. Figure 7 As shown.
