Detailed implementation manners

[0026] The following further elaborates on the content of the present utility model in conjunction with specific embodiments:

[0027] As Figure 1 shown, a fabric material discharging device includes a base 1, on which a positioning mechanism 2 and a material taking assembly 3 are provided. Among them, the positioning mechanisms 2 are symmetrically arranged on the base 1. The material taking assembly 3 has an adsorber 32, which can adsorb the fabric in the previous working station and drive the fabric to move on the base 1 to the working station corresponding to the positioning mechanism 2. Since the adsorption force of the adsorber 32 does not disappear instantaneously when the power is turned off, the positioning pressing plate 23 presses both ends of the fabric on the base 1, so that the residual adsorption force of the material taking assembly 3 will not wrinkle the fabric. A material discharging and transferring mechanism 4 is also provided to transfer the fabric in the positioning mechanism 2 to the material discharging platform 5 for stacking and storage.

[0028] Specifically, as Figure 2 shown, the material taking assembly 3 includes a material taking part 31 provided with an adsorber 32. The material taking part 31 is arranged in a cross-shaped structure, and the adsorber 32 is arranged at the bottom end of the material taking part 31. The cross-shaped structure of the material taking part 31 includes a long side and a short side. Among them, the length of the short side is less than the distance between a pair of positioning mechanisms 2, so that the material taking part 31 can carry the fabric into a pair of positioning mechanisms 2.

[0029] As Figure 3 shown, the positioning mechanism 2 includes a bracket 21, which is arranged in an L-shaped structure. Its horizontal end is fixed to the base 1, and a pressing plate driver 22 is connected to the vertical end. A positioning pressing plate 23 is fixed to the end of the pressing plate driver 22 far from the bracket 21. And the pressing plate driver 22 drives the positioning pressing plate 23 to lift through telescopic movement to realize pressing of the fabric.

[0030] In this embodiment, the pressing plate driver 22 adopts a cylinder. The positioning pressing plate 23 is formed by bending sheet metal, and its dimension along the length direction corresponds to the length dimension of the pressed side of the fabric.

[0031] As Figure 1As shown in the figure, a blanking platform 5 is provided adjacent to the positioning mechanism 2 for carrying stacked fabrics. The blanking platform 5 is arranged on one side of the base 1 and is connected to the base 1 through a lifting component 6, so that during the fabric blanking process, the fabric at the top always remains at the same height, facilitating the blanking transfer mechanism 4 to transfer the fabric from the positioning mechanism 2 to the blanking platform 5.

[0032] Specifically, as Figure 6 shown, the lifting component 6 includes a lifting base plate 61 and a lifting drive mechanism 62. The lifting base plate 61 is arranged in a C-shaped structure and is fixed to one side of the base 1 in the vertical direction. The lifting drive mechanism 62 penetrates through both sides of the lifting base plate 61 along the length direction in the vertical direction and is connected to the blanking platform 5 for driving the lifting of the blanking platform 5. The lifting drive mechanism 62 includes a lifting screw rod 621. Both ends of the lifting screw rod 621 penetrate through the lifting base plate 61, and the bottom end is coaxially connected with a lifting driver 622. The lifting driver 622 drives the lifting screw rod 621 to rotate around its own axis. A lifting slider 623 is arranged in a matching manner on the lifting screw rod 621, and the lifting slider 623 is vertically fixed to the blanking platform 5. And a guide rod 624 is arranged parallel to the lifting screw rod 621. The middle part of the lifting slider 623 is in threaded cooperation with the lifting screw rod 621, and both ends are in sliding cooperation with the guide rod 624. Among them, the lifting driver 622 adopts a servo motor.

[0033] As Figure 4 shown, the blanking transfer mechanism 4 includes a gantry 41 erected on the base 1. A blanking manipulator 43 is installed on the gantry 41 through a linear drive module 42. The linear drive module 42 is arranged parallel to the length direction of the gantry 41 and includes a module driver 421 and a guide rail 422. The execution end of the module driver 421 is connected with a module screw rod. A module slider 424 is arranged in cooperation with the module screw rod and the guide rail 422. The blanking manipulator 43 is connected to the module slider 424 through a vertically arranged blanking driver. Among them, the blanking driver adopts a cylinder, and the cylinder drives the blanking manipulator 43 to lift through telescopic movement to clamp the fabric.

[0034] As Figure 5 shown, the blanking manipulator 43 includes a clamping part 431 and an adjusting part. The clamping part 431 has a plurality of clamping jaws for clamping the fabric, and the adjusting part is used to adjust the distance between the plurality of clamping jaws. The adjusting part includes a first adjusting arm 432 and a second adjusting arm 433 arranged in the horizontal direction. The second adjusting arm 433 is vertically arranged perpendicular to the first adjusting arm 432 and is slidably connected to it. A plurality of clamping jaws are slidably arranged on the second adjusting arm 433. By adjusting the relative position of the second adjusting arm 433 on the first adjusting arm 432 and adjusting the relative position of the clamping jaws on the second adjusting arm 433, the relative position between the plurality of clamping jaws is changed to clamp fabrics of different specifications.

[0035] During use:

[0036] 1. The material taking component 3 adsorbs the fabric from the previous station and drives the fabric to slide and fit on the base 1 to the positioning mechanism 2.

[0037] 2. The positioning pressing plate 23 presses down the fabric driven by the positioning driver to keep the fabric flat and fixed, so as to prevent the residual adsorption force from wrinkling the fabric when the material taking component 3 moves away from the fabric.

[0038] 3. After the material taking component 3 moves away, the positioning pressing plate 23 resets, and the blanking and transfer mechanism 4 takes out the fabric from the positioning mechanism 2 and transfers it to the blanking platform 5 for stacking.

[0039] Since the stroke of the blanking driver driving the blanking manipulator 43 to run each time is the same. Therefore, whenever a new fabric falls onto the blanking platform 5, the lifting component 6 drives the blanking platform 5 to descend by a distance equal to the thickness of one fabric, so that the topmost fabric in the stack always maintains the same height, which is convenient for the blanking work of the blanking manipulator 43.
