A suction cup grabbing device for grabbing cloth

Abstract

The invention provides a suction cup grabbing device for grabbing cloth, which includes a suction cup frame and a suction mechanism arranged on the suction cup frame, and the suction mechanism includes a suction cup arranged on the suction cup frame and a corresponding suction cup provided on the suction cup frame The suction pipe is provided, the top of the suction cup communicates with the suction pipe, the bottom is provided with an air suction port, and the position corresponding to the suction port on the suction cup is provided with an acupuncture assembly for pricking the cloth. The invention has high reliability and can continuously and stably grab the cloth, and this device only uses the suction pipe to provide the suction force. Compared with the existing grabbing device, its energy consumption is lower; by setting the acupuncture component, this The device can move the cloth for a long distance. The needle-punched part set on the suction cup can not only tie the cloth, but also make the cloth move with the suction cup under the double fixation of the suction cup and the needle-punched part to prevent the cloth from falling, and the needle-punched part It can also tie the shaped fabric, which can effectively avoid the deformation of the fabric or block the suction cup.

Description

technical field [0001] The invention belongs to the field of cloth grabbing equipment, and in particular relates to a suction cup grabbing device for grabbing cloth. Background technique [0002] Cloth suction cups are used in the field of automatic sewing machines. They are used to absorb single-layer cloth and implement horizontal or vertical transfer. The existing cloth suction cups have two forms: vacuum adsorption type and non-contact suspension adsorption type. The non-contact suction cup can move the cloth Suction to the suspended state, but when it is suspended and adsorbed, the shape of the fabric is often unstable, and the fabric will inevitably have a certain displacement in the air, so the fabric cannot be accurately and quickly sent to the required processing station. Vacuum suction cups are generally used for fabric suction. and transfer, but the vacuum suction cup is difficult to control the suction force due to the direct vacuum adsorption. For some light and...

[0002] Cloth suction cups are used in the field of automatic sewing machines. They are used to absorb single-layer cloth and implement horizontal or vertical transfer. The existing cloth suction cups have two forms: vacuum adsorption type and non-contact suspension adsorption type. The non-contact suction cup can move the cloth Suction to the suspended state, but when it is suspended and adsorbed, the shape of the fabric is often unstable, and the fabric will inevitably have a certain displacement in the air, so the fabric cannot be accurately and quickly sent to the required processing station. Vacuum suction cups are generally used for fabric suction. and transfer, but the vacuum suction cup is difficult to control the suction force due to the direct vacuum adsorption. For some light and thin fabrics, it is often either unable to absorb or absorb multiple pieces of fabric at one time, and sometimes the fabric is also very easy to fall. , and the suction cup is also easy to cause the fabric to wrinkle or bulge when sucking, causing the fabric to be unable to adapt to mechanical automation sewing, which greatly affects the processing efficiency of the fabric; the existing vacuum suction cup is not suitable for long-distance cleaning of the fabric. Moving, the fabric is easily sucked by the suction cup during the moving process, which not only easily causes the deformation of the fabric, but also easily causes the fabric to fall, which affects the next step of the fabric processing
