Description

Technical Field

[0001] The present application relates to a tile making machine, and more particularly to an automatic blank loading device for a tile making machine. Background Art

[0002] A tile making machine is a mechanical device specifically used for producing various types of tiles and is widely used in the construction industry. With the progress of technology, modern tile making machines not only improve production efficiency and product quality but also can manufacture tiles of various different materials and shapes to meet different architectural design requirements. When a tile making machine works, raw materials (such as clay, cement, sand, etc.) need to be mixed in a certain proportion first, and an appropriate amount of water is added for stirring to extrude into equal-sized block-shaped blanks; then the blanks are formed into tiles of the required shape by pressing.

[0003] With the continuous progress of automation technology, tile making machines have been able to achieve automated production. The blank is grabbed by a grabbing device and put into a stamping machine, and after pressing is completed, the tile blank is taken out by the grabbing device again.

[0004] In the prior art, when the grabbing device grabs the blank and puts it into the stamping machine, since the position of the tile blank on the conveying device may deviate, the blank grabbed by the grabbing device will be skewed, so that the blank cannot be accurately put into the lower tile mold of the stamping machine.

[0005] In view of this, the purpose of the present invention is to provide an automatic blank loading device for a tile making machine that can accurately put the blank into the lower tile mold of the stamping machine. Summary of the Invention

[0006] The content part of the present application is used to briefly introduce concepts, which will be described in detail in the following detailed implementation part. The content part of the present application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0007] To solve the technical problems mentioned in the above background art section, some embodiments of the present application provide an automatic blank loading device for a tile making machine, including a stamping machine and a first conveyor belt and a second conveyor belt arranged on both sides of the stamping machine. A lower tile mold and an upper tile mold are arranged in the stamping machine. It is characterized in that a blank loading mechanism and a blank picking mechanism are movably arranged between the lower tile mold and the upper tile mold along the width direction of the first conveyor belt. The blank loading mechanism includes a blank loading transfer plate movably arranged between the upper tile mold and the lower tile mold. A moving plate is movably arranged on the blank loading transfer plate along the length direction of the first conveyor belt. An upper blank suction cup seat is arranged below the moving plate. A plurality of grasping suction cups are arranged on the bottom surface of the upper blank suction cup seat. A grasping cylinder is fixedly installed on the moving plate. The piston rod of the grasping cylinder is fixedly connected to the upper blank suction cup seat. A calibration component is arranged on the moving plate to calibrate the blank to a position aligned with the upper blank suction cup seat.

[0008] During the working process, the blanks are conveyed at intervals on the first conveyor belt. When the blank is conveyed below the blank loading transfer plate, the moving plate can move along with the first conveyor belt. While the moving plate is moving, the grasping cylinder extends to drive the upper blank suction cup seat to move downward, so that the grasping suction cups approach the upper surface of the blank. During the downward movement of the grasping suction cups, the calibration component can calibrate the blank to a position aligned with the upper blank suction cup seat, so that the grasping suction cups can accurately grasp the blank. After the grasping is completed, the grasping cylinder retracts, and at the same time, the moving plate returns to its initial position. The blank loading transfer plate moves above the lower tile mold, and the grasping suction cups release the blank. Since the calibration component has calibrated the blank, the grasping suction cups can accurately put the blank into the lower tile mold; the upper tile mold of the stamping machine presses down to form the blank, and then the blank picking mechanism moves above the lower tile mold to take out the tile.

[0009] Further, the calibration component includes a first calibration plate and a second calibration plate movably arranged on the moving plate along the width direction of the first conveyor belt. The first calibration plate and the second calibration plate are arranged opposite to each other;

[0010] V-shaped rotating plates are rotatably arranged at both ends of the first calibration plate and the second calibration plate. Calibration wheels are rotatably arranged at both ends of the V-shaped rotating plates.

[0011] Further, mounting holes are formed at both ends of the first calibration plate and the second calibration plate. A rotating shaft is fixedly arranged on the V-shaped rotating plate. The rotating shaft is rotatably connected to the mounting hole through a torsion spring;

[0012] Define the center connection line of the two calibration wheels on the same V-shaped rotating plate as L. In the initial state, L is arranged parallel to the first calibration plate; in the calibration state, L is arranged at a 45° angle to the first calibration plate.

[0013] Further, first limiting posts and second limiting posts are fixedly arranged at both ends of the first calibration plate and the second calibration plate. In the initial state, the side wall of the first limiting post abuts against the V-shaped rotating plate, and in the calibration state, the second limiting post abuts against the V-shaped rotating plate.

[0014] Further, a first guiding plate and a second guiding plate extending along the width direction of the first conveyor belt are fixedly arranged on the moving plate. The first calibration plate is movably arranged on the first guiding plate, and the second calibration plate is movably arranged on the second guiding plate;

[0015] A driving arm is rotatably arranged on the moving plate, and both ends of the driving arm are respectively hinged to the first calibration plate and the second calibration plate through hinge rods.

[0016] Further, a first bevel gear is rotatably arranged on the moving plate. The first bevel gear is fixedly connected to the driving arm. A fixing plate is fixedly arranged on the moving plate. A calibration gear is rotatably arranged on the fixing plate. The calibration gear is coaxially arranged and fixedly connected to a second bevel gear. The second bevel gear is meshed and connected with the first bevel gear;

[0017] A calibration rack is fixedly arranged on the upper blank suction cup seat. The calibration rack is inserted into the moving plate, and the calibration rack can be meshed with the calibration gear when moving.

[0018] Further, a following guiding plate extending along the length direction of the first conveyor belt is fixedly arranged on the upper blank conveying plate. A following guiding block is fixedly arranged on the moving plate. The following guiding block is movably arranged on the following guiding plate;

[0019] A following rack is fixedly arranged on the following guiding block. A following gear is rotatably arranged on the upper blank conveying plate. The following rack is meshed and connected with the following gear;

[0020] A following motor is fixedly installed on the upper blank conveying plate. The output shaft of the following motor is fixedly connected to the following gear.

[0021] Further, conveying racks are arranged on both sides of the punching machine. The first conveyor belt and the second conveyor belt are both arranged on the conveying racks;

[0022] A conveying guiding plate extending along the width direction of the first conveyor belt is arranged above the lower tile mold. The conveying guiding plate is fixedly installed on the conveying rack through a mounting frame;

[0023] The upper blank conveying plate is movably arranged on the conveying guiding plate. A first linear motor is installed on the conveying guiding plate. The first linear motor is fixedly connected to the upper blank conveying plate to drive the upper blank conveying plate to move.

[0024] Further, the blank taking mechanism includes a blank taking transfer plate movably arranged on the transfer guide plate and a cylinder mounting plate fixedly connected to the blank taking transfer plate. A blank taking cylinder is fixedly installed on the cylinder mounting plate. A blank taking suction cup seat is arranged below the cylinder mounting plate. A plurality of blank taking suction cups are arranged on the bottom surface of the blank taking suction cup seat. The piston rod of the blank taking cylinder is fixedly connected to the blank taking suction cup seat.

[0025] Further, a second linear motor is installed on the transfer guide plate. The second linear motor is fixedly connected to the blank taking transfer plate to drive the blank taking transfer plate to move.

[0026] The beneficial effects of the present application are as follows:

[0027] First, before the grasping suction cup contacts the upper surface of the blank, the calibration component can calibrate the blank to a position aligned with the upper blank suction cup seat, so that the grasping suction cup can accurately adsorb on the upper surface of the blank. At the same time, after the position of the blank is calibrated, the grasping suction cup can accurately put the blank into the lower die of the stamping machine.

[0028] Second, the moving seat is movably arranged on the upper blank transfer plate. The moving seat can move together with the blank, and there is enough time for the calibration component to calibrate the blank, avoiding the friction between the blank and the surface of the first conveyor belt caused by intercepting the blank in the traditional way.

[0029] Third, by setting the V-shaped turning plate and the calibration wheel, when the first calibration plate and the second calibration plate are moved, the calibration wheel can contact the side wall of the blank and gradually calibrate the blank to a position aligned with the upper blank suction cup seat.

[0053] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0054] An automatic blank loading device for a tile making machine includes a punching machine 1 and a first conveyor belt 2 and a second conveyor belt 201 arranged on both sides of the punching machine 1. Transfer racks 202 are respectively arranged on both sides of the punching machine 1, and the first conveyor belt 2 and the second conveyor belt 201 are both installed on the transfer racks 202; a lower tile mold 101 and an upper tile mold 102 are arranged in the punching machine 1, and the upper tile mold 102 is movably arranged above the lower tile mold 101 in the height direction of the punching machine 1. The blank 103 is placed in the lower tile mold 101, and when the upper tile mold 102 presses down, the blank 103 can be pressed into a tile 104 corresponding to the shapes of the upper tile mold 102 and the lower tile mold 101.

[0055] The blank feeding mechanism 3 and the blank taking mechanism 4 are movably arranged between the lower tile mold 101 and the upper tile mold 102 along the width direction of the first conveyor belt 2. The blank feeding mechanism 3 can grasp the blank 103 conveyed on the first conveyor belt 2 and convey the blank 103 into the lower tile mold 101. The blank taking mechanism 4 can grasp the tile 104 that has been pressed in the lower tile mold 101 and convey the tile 104 onto the second conveyor belt 201;

[0056] Specifically, two conveying guide plates 5 extending along the width direction of the first conveyor belt 2 are arranged above the lower tile mold 101. The two conveying guide plates 5 are oppositely arranged on both sides above the lower tile mold 101, and both ends of the conveying guide plate 5 are fixedly installed on two conveyor racks 202 through mounting frames 501. The blank feeding mechanism 3 and the blank taking mechanism 4 are both movably arranged on the conveying guide plate 5;

[0057] More specifically, the blank feeding mechanism 3 includes a blank feeding conveyor plate 301 movably arranged on the conveying guide plate 5. The blank feeding conveyor plate 301 is arranged at a position between the upper tile mold 102 and the lower tile mold 101. A first linear motor 502 is installed on one of the conveying guide plates 5. The first linear motor 502 is fixedly connected to the blank feeding conveyor plate 301 to drive the blank feeding conveyor plate 301 to reciprocate. A moving plate 302 is movably arranged on the blank feeding conveyor plate 301 along the length direction of the first conveyor belt 2. An upper blank suction cup seat 303 is arranged below the moving plate 302. A plurality of grasping suction cups 304 are arranged on the bottom surface of the upper blank suction cup seat 303. Two grasping cylinders 305 are fixedly installed on the moving plate 302. The piston rods of the grasping cylinders 305 are fixedly connected to the upper blank suction cup seat 303. A calibration assembly 306 is arranged on the moving plate 302. The calibration assembly 306 can calibrate the position of the blank 103 to align with the upper blank suction cup seat 303 before the grasping suction cups 304 suck the blank 103, so that the grasping suction cups 304 can accurately grasp the blank 103 and precisely convey the blank 103 into the lower tile mold 101;

[0058] Two following guide plates 326 extending along the length direction of the first conveyor belt 2 are fixedly arranged on the blank feeding conveyor plate 301. A following guide block 327 is fixedly arranged on the moving plate 302. The following guide block 327 is movably arranged on the following guide plate 326. A following rack 328 is fixedly arranged on one of the following guide blocks 327. A following gear 329 is rotatably arranged on the blank feeding conveyor plate 301. The following rack 328 is meshed and connected with the following gear 329. A following motor 330 is fixedly installed on the blank feeding conveyor plate. The output shaft of the following motor 330 is fixedly connected to the following gear 329 and coaxially arranged;

[0059] In the static state, the upper blank transfer plate 301 is arranged above the first conveyor belt 2, waiting for the blank 103 to be transferred below the upper blank suction cup seat 303. When the blank 103 is transferred below the upper blank suction cup seat 303, the follower motor 330 starts, driving the moving plate 302 to move together with the blank 103 on the first conveyor belt 2. At this time, the moving speed of the moving plate 302 is the same as the conveying speed of the first conveyor belt 2. During the process of the moving plate 302 following the blank 103 to move, the calibration component 306 can calibrate the blank 103 to align with the upper blank suction cup seat 303. After alignment, the piston rod of the gripping cylinder 305 extends to drive the upper blank suction cup seat 303 to approach the blank 103, so that the gripping suction cup 304 can contact the upper surface of the blank 103 to suck the blank 103. After sucking the blank 103, the gripping cylinder 305 retracts, and at the same time, the follower motor 330 rotates in the reverse direction to drive the moving plate 302 to the initial position. In the conveying state, the first linear motor 502 drives the upper blank transfer plate 301 to move above the lower tile mold 101 to align the upper blank suction cup seat 303 with the lower tile mold 101. At this time, the gripping suction cup 304 puts the blank 103 into the lower tile mold 101. After the blank 103 is put in, the first linear motor 502 drives the upper blank transfer plate 301 to move above the first conveyor belt 2 to restore the initial state;

[0060] More specifically, the calibration component 306 includes a first calibration plate 307 and a second calibration plate 308. The first guide plate 317 and the second guide plate 318 are fixedly installed on two opposite side walls of the moving plate 302. The first guide plate 317 and the second guide plate 318 extend along the width direction of the first conveyor belt 2 and are arranged oppositely. The first calibration plate 307 and the second calibration plate 308 are respectively movably arranged on the first guide plate 317 and the second guide plate 318, and the first calibration plate 307 and the second calibration plate 308 are arranged oppositely. V-shaped rotating plates 309 are rotatably arranged at both ends of the first calibration plate 307 and the second calibration plate 308, and calibration wheels 310 are rotatably arranged at both ends of the V-shaped rotating plates 309. Specifically, mounting holes 311 are formed at both ends of the first calibration plate 307 and the second calibration plate 308. A rotating shaft 312 is fixedly arranged on the V-shaped rotating plate 309. The rotating shaft 312 is inserted into the mounting hole 311 and is rotatably connected to the inner wall of the mounting hole 311 through a torsion spring 313;

[0061] Define the center connection line of the two calibration wheels 310 on the same V-shaped turning plate 309 as L314. In the initial state, L314 is arranged in parallel with the moving plate 302. In the calibration state, L314 is arranged at a 45° angle with the moving plate 302. When it is necessary to correct the position of the blank 103, drive the first calibration plate 307 and the second calibration plate 308 to move towards each other. When the blank 103 abuts against the calibration wheel 310, it can drive the V-shaped turning plate 309 to rotate, so that the V-shaped turning plate 309 rotates to the calibration state, and the calibration wheel 310 can abut against the blank 103 to calibrate the blank to be aligned with the center of the upper blank suction cup seat 303.

[0062] To limit the rotation angle of the V-shaped turning plate 309, the first limit post 315 and the second limit post 316 are fixedly arranged at both ends of the first calibration plate 307 and the second calibration plate 308. In the initial state, that is, when L314 is parallel to the moving plate 302, the V-shaped turning plate 309 abuts against the first limit post 315 to limit the two V-shaped turning plates 309 on the first calibration plate 307 or the second calibration plate 308 from continuing to rotate away from each other. In the calibration state, that is, when L314 forms a 45-degree angle with the moving plate 302, the V-shaped turning plate 309 abuts against the second limit post 316 to limit the two V-shaped turning plates 309 on the first calibration plate 307 or the second calibration plate 308 from continuing to rotate towards each other. The settings of the first limit post 315 and the second limit post 316 enable the V-shaped turning plate 309 to only rotate between the first limit post 315 and the second limit post 316. And when the first calibration plate 307 and the second calibration plate 308 are driven to move away from each other, the blank 103 cancels the abutment with the calibration wheel 310, and the torsion spring 313 can drive the V-shaped turning plate 309 to automatically return to the angle in the initial state.

[0063] A driving arm 319 is rotatably arranged on the bottom surface of the moving plate 302. Both ends of the driving arm 319 are respectively hinged to the first calibration plate 307 and the second calibration plate 308 through hinge rods 320. By rotating the driving arm 319, the hinge rods 320 can be driven to push the first calibration plate 307 and the second calibration plate 308 to move relatively.

[0064] Specifically, a first bevel gear 321 is rotatably arranged on the top surface of the moving plate 302. The first bevel gear 321 is fixedly connected to the driving arm 319. A fixing plate 322 is fixedly arranged on the top surface of the moving plate 302. A calibration gear 323 is rotatably arranged on the fixing plate 322. The calibration gear 323 is coaxially arranged and fixedly connected to a second bevel gear 324. The second bevel gear 324 is meshed with the first bevel gear 321. A calibration rack 325 is fixedly arranged on the top surface of the upper blank suction cup seat 303. The calibration rack 325 is inserted into the moving plate 302 and can be meshed with the calibration gear 323 when the calibration rack 325 moves.

[0065] When the piston rod of the gripping cylinder 305 extends downward to drive the upper blank suction cup seat 303 to move downward, the upper blank suction cup seat 303 drives the calibration rack 325 to move downward. When the calibration rack 325 moves, it can drive the calibration gear 323 to rotate, and then drive the first bevel gear 321 to rotate, thereby realizing the rotation of the driving arm 319. Therefore, when the gripping cylinder 305 drives the upper blank suction cup seat 303 to move downward, it can simultaneously drive the first calibration plate 307 and the second calibration plate 308 to move relative to each other, realizing the calibration of the blank 103. When the calibration of the blank 103 is completed, the gripping suction cup 304 contacts the blank 103 and sucks it. When the gripping cylinder 305 retracts, the calibration wheel 310 cancels the contact with the blank 103 to facilitate the subsequent feeding of the blank 103 into the lower tile mold 101.

[0066] The blank taking mechanism 4 includes a blank taking transfer plate 401 movably arranged on the transfer guide plate 5 and a cylinder mounting plate 402 fixedly connected to the blank taking transfer plate 401. A blank taking cylinder 403 is fixedly installed on the cylinder mounting plate 402. A blank taking suction cup seat 404 is arranged below the cylinder mounting plate 402. A blank taking suction cup 405 is arranged on the bottom surface of the blank taking suction cup seat 404. The piston rod of the blank taking cylinder 403 is fixedly connected to the blank taking suction cup seat 404; A second linear motor 503 is installed on the transfer guide plate 5, and the second linear motor 503 is fixedly connected to the blank taking transfer plate 401 to drive the blank taking transfer plate 401 to reciprocate, taking out the tiles 104 formed in the lower tile mold 101 onto the second conveyor belt 201; In the static state, the blank taking transfer plate 401 is arranged above the second conveyor belt 201 waiting for the blank 103 to be formed by the stamping machine 1. In the blank taking state, the second linear motor 503 drives the blank taking transfer plate 401 to move above the lower tile mold 101, and after taking the blank 103, it conveys the blank 103 to the second conveyor belt 201.

[0067] The specific working principle is as follows:

[0068] The blank 103 is conveyed on the first conveyor belt 2. When the blank 103 is conveyed below the blank sucking seat 303 on the upper die, the follower motor 330 and the grasping cylinder 305 are started simultaneously. The follower motor 330 drives the moving plate 302 to be conveyed together with the first conveyor belt 2, and the grasping cylinder 305 drives the blank sucking seat 303 on the upper die to move downward. During the downward movement of the blank sucking seat 303 on the upper die, the calibration rack 325 can drive the driving arm 319 to rotate. The rotation of the driving arm 319 drives the first calibration plate 307 and the second calibration plate 308 to approach each other, so that the calibration wheel 310 abuts against the side wall of the blank 103, thereby calibrating the blank 103 to the position aligned with the blank sucking seat 303 on the upper die. After calibration, the grasping suction cup 304 on the blank sucking seat 303 on the upper die contacts the upper surface of the blank 103 to suck the blank 103. After sucking the blank 103, the grasping cylinder 305 retracts, and at the same time, the calibration wheel 310 releases the calibration of the blank 103. The first linear motor 502 drives the blank conveying plate 301 on the upper die to move above the lower tile mold 101, and the grasping suction cup 304 releases the blank 103, and accurately puts the blank 103 into the lower tile mold 101. Subsequently, the first linear motor 502 drives the blank conveying plate 301 on the upper die to return to the initial position to wait for conveying the next blank 103. After the stamping machine 1 presses the blank 103 in the lower tile mold 101, the second linear motor 503 drives the blank picking conveying plate 401 to move above the lower tile mold 101, and the blank picking cylinder 403 drives the blank picking seat 404 to move downward to suck the tile 104. Subsequently, the second linear motor 503 drives the blank picking conveying plate 401 to move above the second conveyor belt 201 and throws the tile 104 onto the second conveyor belt 201.

[0069] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure that have similar functions.
