The screw holes on the bin bottom plate 21 and the bin side plate 22 can be provided with multiple, so as to facilitate the position adjustment of the triangular plate material blocking piece 24 and facilitate the bin to place triangular plate materials of different sizes.

[0023] Preferably, the pressing rod mounting seat 27 can include a mounting block 271 and a linear bearing 272. The mounting block 271 is provided with a position adjustment hole 2711 arranged along the length direction thereof. The linear bearing 272 is installed on the mounting block 271.

[0024] Preferably, as shown in the drawings, Figure 4 The material blocking spring piece 28 can be provided with multiple layers of spring sheets 281 arranged at intervals, and all the spring sheets 281 are inclined downward. The material blocking spring piece 28 plays a supporting and distributing role. The triangular plate materials are blocked by multiple layers of spring sheets, so that only one material can pass under the blocking of the spring sheets each time, thereby ensuring the accuracy of the action and the quality of the product and reducing the defective rate.

[0025] As shown in the drawings, Figure 2As shown, the bottom plate 21 and / or the side plate 22 of the hopper are respectively provided with photoelectric sensors 210 (such as laser sensing) for detecting the stacking height of the triangular plates.

[0027] The working principle of the utility model is as follows:

[0028] When it is needed to put triangular plate materials into the triangular plate hopper 2, the operator can manually lift the gravity pressing plate 25, and when enough triangular plate materials are put in, the gravity pressing plate 25 is loosened, so that the gravity pressing plate 25 presses the triangular plate materials under the action of gravity, and when the triangular plate materials are repeatedly taken by the vacuum suction cups 313, the stacking height of the triangular plates will be lowered, and when the photoelectric sensor 210 detects that the stacking height of the triangular plates is lowered to the preset position, the system sends a prompt, and the operator hears the prompt sound and comes to supplement the stacking of triangular plate materials, which is recycled in this way.

[0029] In the repeated material taking process of the vacuum chuck 313, the motor 31 can drive the driving turnover connecting rod 33 to rotate through the first synchronous belt 310, and the turnover arm 34 turns a certain angle according to the program, since it is planetary transmission, the driven turnover connecting rod 35 and the fourth synchronous wheel 39 are also synchronously turned under the drive of the second synchronous belt 311, and since there is a difference in the number of teeth between the third synchronous wheel 38 (large synchronous wheel) and the fourth synchronous wheel 39 (small synchronous wheel), the fourth synchronous wheel 39 itself has a faster self-rotation angle, when the turnover arm 34 turns to the position, the driven turnover connecting rod 35 simultaneously completes a larger angle of turnover than the turnover arm 34, at this time, the taking and placing cylinder 312 is extended, the vacuum chuck 313 takes the lowermost triangular plate material at the bottom outlet of the material bin, at this time, the one-way material taking is completed.

[0030] When the vacuum chuck 313 is adsorbed to the triangular plate material, the taking and placing cylinder 312 is retracted, the motor 31 is turned, and is swung to the placing position (such as the positioning platform 4 or other specified position shown in the drawing) according to the program direction, then the taking and placing cylinder 312 is extended, the vacuum chuck 313 places the triangular plate material, and the placing action is completed. In this way, the turnover type material taking and plate taking device 3 will reciprocate and turn according to the program. Figure 1

[0031] In summary, the structure of the utility model is reasonable in design, the non-stop triangular plate material bin structure is adopted, the triangular plate material can be manually stacked under the condition of non-stop, the stability of the taking and placing action of the turnover type material taking and plate taking device is good, the running speed is fast, and the working efficiency of the whole machine is greatly improved.

[0032] The above embodiment is the preferred embodiment of the utility model, but the embodiment of the utility model is not limited by the above embodiment, any change, modification, replacement, combination and simplification without departing from the spirit and principle of the utility model should be equivalent replacement, and all are included in the protection scope of the utility model.​
