Description

Technical Field

[0001] The utility model relates to sewing equipment, in particular to sheet material sewing equipment with multiple machine heads. Background Art

[0002] Sheet material sewing machines are specialized for processing sheet materials and are widely used in the clothing, footwear, hats, luggage, and other industries.

[0032] a reciprocating conveying device 200 , which can reciprocate between the first sewing station and the second sewing station along a first direction X to convey the sheet material from the first sewing station to the second sewing station;

[0033] A first sewing head 300, corresponding to the first sewing station, is used to sew the first side edge of the sheet;

[0034] A second sewing head 400, corresponding to the second sewing station, is used to sew the second side edge of the sheet;

[0035] The first sewing head 300 and the second sewing head 400 are respectively located on both sides of the reciprocating conveying device 200 along the second direction Y, and the first direction X is perpendicular to the second direction Y.

[0036] The sheet material sewing device of the present invention is provided with a first sewing head 300 and a second sewing head 400 for sewing the opposite sides of the sheet material respectively. First, the automatic loading device or the worker delivers the sheet material to the first sewing head 300 located on the first sewing station, and the first sewing head 300 sews the first side side of the sheet material. Then, the reciprocating transfer device 200 grabs the sheet material located on the first sewing station and transfers the grabbed sheet material to the second sewing head 400 located on the second sewing station, and the second sewing head 400 sews the second side side of the sheet material. Finally, the automatic unloading device or the worker takes the sheet material away from the second sewing station, thereby achieving the purpose of sewing the opposite sides of the sheet material respectively without turning the sheet material over.

[0037] like Figure 2 As shown, the reciprocating transfer device 200 includes a gantry bracket 210 and a first reciprocating transfer mechanism 22a and a second reciprocating transfer mechanism 22b arranged in parallel on the gantry bracket 210. The first reciprocating transfer mechanism 22a and the second reciprocating transfer mechanism 22b are located above the first sewing station and the second sewing station, and are used to grab the opposite sides of the sheet when transferring the sheet, so as to improve the grabbing ability of larger sheets.

[0038] like Figure 3 As shown, the first reciprocating transfer mechanism 22a and the second reciprocating transfer mechanism 22b both include a transfer driver 221, a transfer slide 222, a transfer slide 223, a lifting driver 224 and a grabbing robot 225.

[0044] When adjusting the position of the needle suction cup 2252, first loosen the screws and bolts connecting the mounting piece 2253 and the mounting bracket 2251, so that the needle suction cup 2252 can drive the corresponding mounting piece 2253 to move to other positions along the second direction Y relative to the mounting bracket 2251 under the action of external force. After completing the position adjustment, tighten the screws and bolts connecting the mounting piece 2253 and the mounting bracket 2251.

[0045] Preferably, the mounting holes 2254 of each mounting piece 2253 extend along the first direction X, so that the mounting position of each pin suction cup 2252 on the mounting bracket 2251 can be adjusted along the first direction X. The method for adjusting the mounting position of each pin suction cup 2252 along the first direction X is the same as the method for adjusting the mounting position along the second direction, and will not be repeated here.
