A kind of sponge material feeding grabbing device
Technical field
The features such as the utility model relates to a kind of sponge material feeding grabbing device, and this device is used for capturing sponge material, can overcome sponge bulk, yielding, realize the effective sponge material capturing difformity and model.
Background technology
Sponge is a kind of porous material, is generally made up of wood cellulose fibers or foamed plastic polymer.It is good that the foam-rubber cushion made by sponge has aeration, the features such as soft comfortable, and being therefore widely used in brassiere, formal dress etc. needs in the dress ornament of sizing.But sponge is due to bulk porous, the feature such as easily deformable, be difficult in Manufacturing Automated process capture.Along with improving constantly of process automaticity, it is also proposed higher requirement to the grabbing device of sponge material, can sponge material capture the efficiency directly affecting automatic assembly line effectively rapidly.
At present, sponge adds the modes such as the manual feeding of many employings in man-hour, vacuum cup, mechanical grip, but these modes all also exist wretched insufficiency, such as: manual feeding easily causes the problems such as feeding time is long, production efficiency is low, operate miss is high; Again such as: because sponge permeability is strong, gas is easy to disperse, vacuum cup absorption affinity is little, absorption is unstable, so adsorption effect not obvious; Mechanical grip mode is more infeasible, and sponge has softness, bulk, stressed yielding, in irregular shape feature, and mechanical grip is difficult to accomplish to stablize with accurate.So we are according to the feature of sponge self, invent a kind of grabbing device based on pinprick mode, effectively can make up the deficiency of above various mode.
Summary of the invention
The purpose of this utility model is to provide a kind of sponge material feeding grabbing device that can adapt to different model sponge material, overcomes sponge bulk, yielding, the difficult feature captured, and realizes capturing sponge material fast and effectively.
The utility model is achieved through the following technical solutions: this sponge material feeding grabbing device comprises a two output shaft electric machine, the contrary screw rod of rotation direction is equipped with at the two ends that motor shaft is overhanging respectively, screw rod is through the bearing that nut is housed, two bearings are fixed by screwed hole with slide block respectively, slide block simultaneously and chuck contiguous block fix, frame is stuck between slide block and chuck contiguous block, forms moving sets between slide block and frame.Chuck there is the installing hole of cylinder, a little cylinder is housed.Cylinder axis end is connected with acupuncture treatment seat by extension shaft, acupuncture treatment seat is circumferentially evenly equipped with the sewing-needle of 6 use in sewing machine.Cylinder goes out in axial end and be fixed with cylinder holder, cylinder holder is connected by two guide pillars with stripper plate, and cylinder axis drives acupuncture treatment to move between cylinder holder and stripper plate along guide pillar.The dependency structure of two claws is identical.Frame is equipped with sensor mount simultaneously, a slide block is equipped with inductor sensor block.
Position detection components comprises sensor mount and position sensor, described position detection components can realize adjusting part back to zero and left and right spacing.Described motor and bolt and nut adjustment structure, can regulate the spacing of two claws, so that capture the sponge material of different size.
In said structure, described crawl structure is when near sponge material, and cylinder rod stretches out, and drives acupuncture treatment to prick into sponge material, relies on the frictional force of acupuncture treatment to capture sponge.When needing to unload sponge material, cylinder rod is retracted, and inside acupuncture treatment retraction stripper plate, sponge material is blocked by stripper plate and comes off.
Compare the mode such as vacuum suction, mechanical grip, this sponge grabbing device has the following advantages: the reliable crawl that 1. can realize sponge material; 2. the sponge material of different model can be captured by adjustment two pawl spacing; 3. structure is simple, and be quick on the draw, cost is lower, can meet the automation process requirement rapidly and efficiently of sponge material preferably.

Detailed description of the invention
In fig 2, motor 1 is fixed on motor support base 17 by installing hole, and motor support base 17 is fixed in the square groove of frame 1, two output shafts connecting screw rod 16,17 respectively of motor 1, screw rod, through two bearings 15, is equipped with nut 14, is fixed between nut 14 and bearing 15 by holding screw in bearing.Bearing 15 is fixed with bolt by counter sink and slide block 20, and slide block 20 and chuck contiguous block 2 are fixed by installing hole bolt, and group and the frame 1 of slide block 20 and chuck contiguous block 2 one-tenth form moving sets, and slide block 20 is embedded in the square groove of frame 1.This device has two claws, and the structure of two claws is identical with connected mode.Now be illustrated with one of them.Bolt is connected with the screwed hole of cylinder 3 by the counter sink of chuck contiguous block 2, and cylinder holder 4 is fixed on another end face of cylinder, with bolt by counter sink and screwed hole fastening.Extension shaft 5 is through cylinder holder 4, and two ends connect cylinder 3 axle and acupuncture treatment seat 8 respectively, and guide pillar 7 is through acupuncture treatment seat 8, and two ends are fixed with cylinder holder 4 and stripper plate 9 respectively, and screwed hole has been attacked at guide pillar 7 two ends, and axis bolt is fixed.There is guide pin bushing 6 in the hole of the acupuncture treatment seat 8 that guide pillar 7 passes, reduce friction.Acupuncture treatment seat 8 is circumferentially uniformly distributed 6 holes, is used for installing acupuncture treatment 10, acupuncture treatment 10 is fixed by the screwed hole holding screw of to have an acupuncture treatment on seat 8 radially.This device is when capturing sponge material, and cylinder 3 stretches out, and drives acupuncture treatment seat 8 to prick into sponge material, relies on the frictional force of acupuncture treatment 10 to capture sponge.When needing to unload sponge material, cylinder 3 is retracted, and have an acupuncture treatment inside 10 retraction stripper plates 9, sponge material is blocked by stripper plate 9 and comes off.
In fig. 3, sensor stand 11 is arranged in frame 1 by through hole, sensor stand has three inductor installing holes, is used for installing inductor 13, and sensor block 12 is arranged on the slide block 20 of inductor, is used for detecting and limiting two pawl spacing.Frame 1 there is installing hole, for being connected with other devices.
