A method for grabbing a fabric and a method for destacking the fabric

Abstract

The invention discloses a fabric grabbing method. The fabric grabbing method comprises the following steps that A1, a claw portion of a flexible clamping claw is opened and moves to the upper surfaceof stacked fabric to be in contact with the fabric at the uppermost layer; A2, the claw portion of the flexible clamping claw is gradually closed and rubs up the fabric at the uppermost layer to enable the fabric at the uppermost layer to be raised upwards to form a bulge; and A3, the flexible clamping claw moves upwards, meanwhile, the claw portion continues to be closed, clamps the middle portion of the bulge of the fabric at the uppermost layer and then lifts the fabric at the uppermost layer. According to the fabric grabbing method, the fabric is directly grabbed through the flexible clamping claw, and it is guaranteed that only one piece of fabric is grabbed during grabbing each time. In addition, a fabric de-stacking method utilizes the fabric grabbing method, then the stacked fabriccan be grabbed one by one and moved to the target position, and the whole de-stacking process is accurate and reliable.

Description

technical field [0001] The invention relates to a grabbing method for fabrics, and also relates to a destacking method for unstacking stacked fabrics by using the grabbing method. Background technique [0002] At present, in the garment manufacturing industry, how to grab fabrics is a difficult point in the industry. At present, there are mainly two situations where fabrics need to be grabbed. 1. It has always been a technical problem in the industry to separate the piles of fabrics cut by the cutting machine one by one; 2. Grab a single piece of fabric, move it to the target position or stack it after grabbing. [0003] Therefore, the current grasping methods of fabrics mainly include the following types: 1. Suction cup absorption. Due to the breathable material of the fabric, this suction cup absorption method is difficult to realize, and the vacuum degree is difficult to grasp. If the vacuum degree is too high, multiple pieces of fabric will be absorbed. 2. Acupuncture g...

[0007] 2. Since the friction wheel of the sorting device needs to completely rewind the top layer of fabric and drop it onto the grabbing plate, at the same time, the friction wheel will stop after the top layer of fabric falls on the grabbing plate, so when the top layer of fabric falls During the process, the friction wheel will still rub against the second layer of fabric, so it may cause the end of the second layer of fabric to wrap around the friction wheel, so the separation is not accurate

[0008] 3. When this kind of sorting device separates a piece of fabric and places it at the target position, it is difficult to ensure the placement position, and it is also difficult to pave the separated fabric
