Technical background
The China's Mainland is to make one of main place of production of clothes, also is the production base of various sewing devices.Owing to rising steadily of manpower and Material Cost over year recently, make to be faced with huge pressure by this labor-intensive product of garment production.So the automaticity high product is being gone into overdrive to develop in each big sewing device production commercial city, to substitute old-fashioned a large amount of work by manually finishing.Making on the operation of all kinds of Costume buttons, all adopt button-sewing machine to replace manual nail catcher now basically, but finish at a button, when following closely next button, also to lean on the workman to get button by hand, and button is filled in button-sewing machine clip position, also will aim at the position of buttonhole and eedle simultaneously.The high concentration of the very skilled and spirit of this technology that just needs the workman.Usually nail one button only needs the time in several seconds, and working strength of workers is well imagined at the end of the day.Putting before this, a kind of importance of equipment of automatic transport button is just self-evident.
Cylinder control a kind of of stroke that external some manufacturer production has gone out more complicated send button equipment, but the cost of this equipment is too high, and maintenance is difficulty relatively, and the market difficulty is promoted the use of on a large scale at home.
Summary of the invention
The present invention is in order to adapt to the needs of domestic market, being intended to provides the high electric-machine directly-driven cam link formula of a kind of cost performance to send buckle device automatically and send the button method to this area, it is more to make it solve the same category of device parts, structure is the complicated technology problem comparatively, and solves price higher cost problem.The present invention is the auxiliary equipment of all kinds of nail catchers, is to select for use electric-machine directly-driven cam link formula to send buckle device automatically, and the present invention is achieved by the following technical solutions.
The inventive system comprises the clinching assembly, send buckle assembly, casing, the clinching assembly is made up of clinching axle rotating part and clinching axle depressed portion, described clinching axle rotating part comprises stepper motor, big synchronous pulley, be with synchronously, small synchronous pulley, the clinching axle sleeve, bearing clinching axle, described stepper motor is connected with casing, described big synchronous pulley links to each other with the motor shaft of stepper motor, described small synchronous pulley links to each other with the clinching axle sleeve, described two belt wheels are linked to each other by synchronous band, described two bearings are directly installed on the two ends up and down in the chassis hole, described clinching axle sleeve is installed in two dead eyes, and described clinching axle is arranged in the clinching axle sleeve; Energising back step motor shaft begins to rotate back and forth, and drives clinching axle sleeve and clinching axle and does 300 ° swing back and forth.
Described clinching axle depressed portion comprises clinching electromagnet, fork connecting rod, clinching axle fork, piece endwisely slips, described clinching electromagnet is arranged in the casing, described fork connecting rod one end connects the clinching electromagnet by screw, the other end connects clinching axle fork by screw, described clinching axle fork centre bore links to each other with casing, the other end is arranged in the piece groove that endwisely slips, and the described piece that endwisely slips connects the clinching axle.In described stepper motor energising, the clinching electromagnet also can be switched on, and swings by the adhesive pulling clinching axle fork of electromagnet, and drives the axially motion down of clinching that is swinging by the piece that endwisely slips, the button of below is pressed onto on the button positioning seat, finishes the clinching action.
The described buckle assembly that send comprises spindle motor, shaft coupling, last axle, send the button cam, send the button cam swing, the cam swing roller, the oscillating bearing link assembly, send the button crank, send the button axle, send the button fork, the button positioning seat, casing connects goes up spindle motor and last axle, axle links by shaft coupling on the described upward spindle motor, the described button cam that send is connected with last axle, described button cam swing one end that send connects casing, described cam swing roller one end send the button cam swing by being threaded in, the other end places in the cam path that send the button cam, the described button crank that send send the button cam swing by the connection of oscillating bearing link assembly, describedly send button axle upper end to connect to send the button crank, describedly send the button fork to be installed in to send a button axle lower end, described button positioning seat is detained fork and is connected with sending.
Described big synchronous pulley links to each other by being with synchronously with small synchronous pulley, is directly driven by stepper motor, makes the clinching axle reach reciprocal rotation.
The described spindle motor of going up connects casing, links by shaft coupling and last axle, makes that going up spindle motor directly drives axle.
Spindle motor begins rotation on when the clinching action is finished, the rotation of button cam is sent in drive, and send the button crank by sending button cam swing, cam swing roller, oscillating bearing link assembly to spur, send the button axle, send button fork, button positioning seat to do counterclockwise about 90 ° swing, make button deliver to button-sewing machine clip position fast and accurately, momentary reset is prepared for send button next time then.
The present invention selects for use the electric-machine directly-driven transmission comparatively steady, sensitive, quick, and it is comparatively convenient to keep in repair, and structure is comparatively compact, and especially parts are less, and manufacturing cost is lower, raises labour efficiency.Belong to the auxiliary equipment of sending button up to now, do not need source of the gas, parts are less, and structure is comparatively simple, and cost performance is higher, is adapted at the device that promote the domestic market on a large scale.
Specific implementation method
By reference to the accompanying drawings 1~3, implementation method of the present invention is described below.
Part name in the accompanying drawing and sequence number: casing 1, stepper motor 2, big synchronous pulley 3, be with 4 synchronously, small synchronous pulley 5, clinching axle sleeve 6, bearing 7, clinching axle 8, clinching electromagnet 9, fork connecting rod 10, clinching axle fork 11, the piece 12 that endwisely slips, go up spindle motor 13, shaft coupling 14, go up axle 15, send button cam 16, send button cam swing 17, cam swing roller 18, oscillating bearing link assembly 19, send button crank 20, send button axle 21, send button fork 22, button positioning seat 23.
What electric-machine directly-driven cam link formula was sent buckle device automatically send the button method: by described stepper motor 2 by described synchronous pulley and drive rotating back and forth of clinching axles 6 with 4 synchronously, and clinching electromagnet 9 presses down in rotation by clinching axle fork 11 drive clinching axles 8, and button accurately is placed on the button positioning seat 23; Directly driven by last axle by the last spindle motor 13 in the casing again and send button cam 16, send the button cam swing 17 swings by described cam driven, make send buckle assembly send button crank 20 to drive to send button axle 21 and send button fork 7 outwards to swing, button is put implement to button-sewing machine clip position and sent button, clinching axle fork 11 is inwardly swung and is resetted then, finishes one and send the button operation; Finish one and another button operation, the working procedure of mating clothes nail catcher equipment sent thereby go round and begin again.
