Background technology:
Polyurethane cellular center-filled product is that polyurethane material is sprayed on Chopped Strand Mat, and then Chopped Strand Mat and honeycomb paper, foaming in mould produces cellular type core product; Honeycomb paper is positioned at the centre of two-layer Chopped Strand Mat, and the Chopped Strand Mat on two sides all wants spraying polyurethane material.Chopped Strand Mat on the one hand after spraying polyurethane material is difficult to manual moving, on the other hand, and the moulded from foam as early as possible of the material require after spraying, otherwise foamed before being put in mould, the outward appearance of product and performance all can have impact.For this reason, the technique that batch production adopts at present is that Chopped Strand Mat is become sandwich structure with honeycomb paper lay, then captures material by robot, sprays, then by robot, material is sent within mould.
As shown in Figure 1, polyurethane material is sprayed by the spray material port 2 of spray equipment 1, and shape is roughly a solid conical, fall the shape on material, as shown in Figure 3, Shi Yige center is many, the shape reduced gradually to edge, because the atomization of polyurethane material, has unsharp edge 4.
After material captures with robot, as shown in Figure 5, the left and right sides of material 6 is clipped between left gripping arm 7 and right gripping arm 8.As shown in Figure 6, the polyurethane material be atomized can be fallen in the gripping arm of the right and left, and in the process toward spraying polyurethane material on material 6, left arm 7 and right arm 8 can be subject to the pollution of polyurethane material.So the gripping arm that robot captures material will maintain a certain distance with spraying area.That is, in order to spray the region of width 1000mm, need to use the width 1100 even material of 1200mm.The region of middle 1000mm is spraying area, additional 100-200mm, and except leaving for except robot captures, also will reserve a part of width specially, be prevent the polyurethane material be atomized from falling in gripping arm, accumulates gradually and affects the function of gripping arm.
Nonetheless, still having a small amount of polyurethane material falls in gripping arm, and accumulate gradually in process of production, gripping arm becomes more and more dirtier, not only affect outward appearance, and the polyurethane material fallen above can continue the glass that bonds, bond more polyurethane material, final more long-pending larger, affect the function of gripping arm.For this reason, before the function of gripping arm is subject to significantly impact, just needs to stop producing, gripping arm is cleared up.
The time that gripping arm is dirty and gripping arm are to the distance negative correlation of spraying area.That is, the gripping arm of spraying area distance is far away, and gripping arm is more not easy dirty, but material will be larger like this, produces same product and can waste more material.
Also someone proposes to adopt and in gripping arm, arranges baffle plate to protect gripping arm, but, very fast dirty, thickening because of the attachment of spray paint on baffle plate, affect the function of gripping arm, cleaning gripping arm is made into clear up the too not large practical significance of baffle plate.
Somebody proposes, near nozzle, adopt baffle plate to block spray paint, in fact, except spray paint attachment, change the state of baffle plate, from the material of spray material port ejection, after baffle plate blocks, continuing in the process fallen, by airflow influence, the material still having quite a few atomization drops in gripping arm.

Detailed description of the invention:
In order to Comprehension and Implementation better, provide specific embodiment below in conjunction with accompanying drawing and describe the present invention in detail, illustrated embodiment only for explaining the present invention, not for limiting the scope of the invention.
Embodiment 1; see Fig. 2,5; adopt existing spray equipment 1; at the correct position on spray material port 2 side of spray equipment 1, puff prot 3 is set; from the gas of puff prot ejection, the polyurethane material of atomization is grabbed wall 8 from left gripping arm 7 and the right side and blows away, thus reduction polyurethane material falls the probability in gripping arm; puff prot 3 is positioned at the both sides of spray material port 2, thus the gripping arm of the protection left and right sides.
Adopt the spray equipment of above-described embodiment 1, the production method of polyurethane coating product is that Chopped Strand Mat is become sandwich structure with honeycomb paper lay, then material 6 is captured by robot, spray, in spray coating process, adopt the special purpose device of embodiment 1, from the gas that puff prot 3 sprays, the polyurethane material of atomization is blown away from gripping arm, thus reduction polyurethane material falls the probability in gripping arm, then by robot, material 6 is sent within mould, compression molding.
As shown in Figure 2, the material just sprayed from spray material port 2 and be just all circular from the gas of puff prot 3 ejection, then continue to whereabouts, two circles affect each other, and centre eats up mutually one piece; After falling on material, shape as shown in Figure 4, is no longer the clear circle of a blur margin, but pruned near puff prot side one piece arc, bowstring side defines a profile more clearly.
As preferred scheme, puff prot is not spray gas in spraying process always, but when the material sprayed drops near the gripping arm of the material left and right sides, just starts jet.As shown in Figure 5, when spraying Far Left one, the puff prot in left side receives signal, starts to spray gas, protects left gripping arm 7, pollutes from spray paint; When spraying rightmost one, the puff prot on right side receives signal, starts to spray gas, protects right gripping arm 8, pollutes from spray paint.After having sprayed as shown in Figure 7, the position of close left gripping arm and right gripping arm, polyurethane material has profile clearly, and the degree that gripping arm is polluted is very little.
This gas can be compressed air, the jet signal of puff prot, can be the run location of robot according to gripping arm, set in the running orbit file of robot, such as when spraying leftmost one, the puff prot in left side starts, when spraying rightmost one, the puff prot on right side starts.
Control the signal of puff prot, the sensor of detection gripping arm position also can be adopted to realize.In time sensing that gripping arm is close, open the puff prot of corresponding side, when gripping arm away from time, close puff prot stop jet.
The sensor of detection gripping arm position is impact switch, and according to the width of gripping arm, when right side gripping arm is near spray material port, left side gripping arm encounters impact switch just, thus the puff prot triggering right side is jet, and same symmetric design is also done in side in addition; What this mode more can alleviate spraying profile writes workload, thus automatically realizes gripping arm protection.
The production method of a kind of polyurethane coating product of the present invention and special purpose device thereof, after the side of spray material port arranges puff prot, as shown in Figure 2, because gas is on the impact of material, solid circular cone has just been pruned one piece and has been become asymmetric, material near puff prot side is just few, and the edge of this side can be very clear, as shown in Figure 4.When spray left and right two row, open corresponding puff prot, greatly will alleviate the pollution level of gripping arm, as shown in Figure 7.Thus need not scantling be increased, do not need to clear up gripping arm continually yet.
