Description

Device for interchangeable connection

The applying device of working arm coating can inside in the relevant jar of a kind of usefulness of the present invention is particularly changed and the piecing devices that are connected rapidly with the nozzle arm in the nozzle arm about the link arm that this working arm is included.

In the jar inner coating equipment, do the spraying of various purposes with various shower nozzles and corresponding nozzle arm, for example make spraying of powder glazed agent and wet spray.Generally speaking, in jar in the processing equipment, again for example in jar in the dusty spray melting unit, the station on the working arm in stretching into jar must be changed more frequently.

Though spraying equipment in the jar that uses at present, its nozzle arm can exchange, but the replacing process costs considerable time, because before new nozzle arm part is installed on the working arm of coating device, must be with coating media, air, all supplies and the discharge conduit of electric current or the like cut off respectively, connect respectively again then and lock.

Therefore, the purpose of this invention is to provide a kind of device, it makes the rapid jar nozzle arm of interior work system of changing partly become possibility.

Applying device according to working arm coating can inside in jar of usefulness of the present invention, this working arm comprises a link arm and a nozzle arm that has shower nozzle, this shower nozzle is provided with the nozzle arrangements that is used to apply can inside, it is characterized in that, this coating can internal work arm includes a plurality of pipelines for the different operating application from wherein extending, these needs of work different shower nozzles that have different nozzle structures and applicator element, thereby the whole pipelines that occur in link arm or some of them pipeline continue in nozzle arm, the nozzle arm that has shower nozzle has rapid pipe joint, be connected with link arm replaceably by a locking device, this locking device is guaranteed being connected of link arm and nozzle arm, make the pipeline that continues in the nozzle arm reliably with link arm in corresponding pipeline couple together so that can use shower nozzles different on the nozzle arm apace.

According to device of the present invention, preferably on nozzle arm and the link arm surface plane or curved surface is arranged respectively, and have at least a locking element that contact surface is pressed on together.

For replaceable part is installed, for example in jar, on the tram of the link arm of processing equipment nozzle arm is installed, locating piece also is set in addition, preferably is located on the contact surface, these elements make locking element only with respect to two surfaces give on the fixed position time just produce the locking effect.

When will such as the sector of breakdown of nozzle arm with jar in the link arm of processing equipment be connected the time, importantly will supply with and the discharge conduit connection coating agent for example, electric current, the pipeline connection of surveying instrument etc.

For accomplishing that this point depends on the locking effect of locking element, makes arm and mounting portion that being connected of reliable running be arranged.For example, being provides the sealing of pipe joint when the connection of tram is arranged between contact surface, perhaps when contact surface is connected connection-peg is exposed.

May when a part is connected rapidly, pollute by contact surface, be difficult to two contact surfaces are compressed contact.For this reason,, also propose to arrange at least a seal ring, for example on the periphery of a contact surface, utilize the locking effect that two surfaces are tightly connected in dividing other plane for obtaining the flexible locking effect.In this case, contact surface needn't be done the direct contact of impaction state.

For contact surface is compressed mutually, suggestion uses telescopic nut to make locking element, in the hope of simplifying.Even preferably the threaded bush be designed to rotate a quite little angle, just can guarantee the locking effect.

In another program of the present invention, the bayonet socket lock pin is used in suggestion, and locking element forms its part.

Another style of scheme, the suggestion latch fitting has the form of fricton-tight plug.The Design of length of plug or socket must make the part in the inserting state not do any deflection with respect to arm.The surface of this joint or socket internal surface, the most handy made that high surface friction is arranged.So between socket and plug the highest surface friction drag is arranged.For example material can be with synthetic resin or elastic rubber material.Have only by external force during the plug pin and just can unplug.

Device of the present invention is particularly useful for a can applicator head, and a part as the jar inner coating equipment is installed on its arm.

To device of the present invention, with reference to the accompanying drawing narration, accompanying drawing thes contents are as follows as an example:

Fig. 1 shows vertically analysing and observe of apparatus of the present invention,

Fig. 2 is along Fig. 1, and a part of contact surface of A-A line is overlooked,

Fig. 3 shows the bayonet lock pin part of making locking element,

Fig. 4 shows the fricton-tight plug of making locking element.

Fig. 1 is the quick change joint of 2 of nozzle arm 1 and can seam coating device link arms.End face at nozzle arm 1 and link arm 2 is provided with contact surface 3 and 4, and these surfaces are compressed mutually.

Telescopic nut 8 is installed on the sliding seat 5 of link arm 2, and this telescopic nut is screwed on the outside thread 12 of spray arm with internal thread 10.For example, the fritter 9 of projection on the telescopic nut can be pushed away the outside thread 12 of nozzle arm, and, make elasticity and install for example by the axial slots on the telescopic nut 8.

Supply that nozzle arm 1 and link arm are 2 and discharge pipe 6 are tightly connected by contact surface 3 and 4.

When changing nozzle arm 1, telescopic nut 8 is unscrewed, up to two contact surfaces 3 and 4 of nozzle arm 1 can being separated with link arm 2.For example, now will apply large-area relatively nozzle arm 1 removal, for example change the nozzle arm of the relative small size of coating.When new nozzle arm 1 is laid, the be posted by connecting contact surface 4 of arm 2 of contact surface 3.At this moment, tighten telescopic nut 8, two contact surfaces 3 and 4 are compressed.

On contact surface 3 and 4, arrange pin 14(Fig. 2) and corresponding pin-and-hole, before two contact surfaces 3 and 4 were compressed, supply accordingly and discharge conduit 6 aligned in the time of must both place certainly.After nozzle arm 1 locking that will newly change with telescopic nut 8, being connected to form of pipeline guarantees to do reliable running, utilizes the tension of telescopic nut 8, such as tightening seal, makes new nozzle arm 1 running.

As seen from Figure 2, contact surface 3 has the seal ring 16 on the periphery.With commercially available plug with contact lip-deep respective socket relatively, circuit 6e is connected.For example make circuit 6a with optical fiber cable.If conduit 6b carries powder glazed agent and air, conduit 6c absorbs the powder that does not adhere to.Conduit 6d is used to supply with wet glazed agent, makes that powder coating is replaceable to be wet glazed agent applicator head.If conduit 6f makes applicator head expose to high-field electrode, electrode exposes in air, does not crust in the above just have coating agent.For with

conduit

6b, 6c, 6d, the 6f joint seals respectively, and packing ring 18 is established in conduit terminal and 3 or 4 joints, surface, guarantees joint sealing.

If now the contact surface 3 of spray arm and the corresponding contact surface 4 of link arm are docked, will sell then in 14 grooves that insert on the link arms.Because the positioning action of pin and groove, the contact surface of corresponding pipeline 6 aligns and connects, and for example is tightly connected, and guarantees the reliable operation in the locking process.

Fig. 3 and 4 shows and uses the snap action joint, other methods availalbes that a nozzle arm part is connected with link arm.

In Fig. 3, a nozzle arm part 21 and link arm 22 are locked with the bayonet socket lock pin.The pin 26 of part 21 is passed through latch groove 27, among the guide groove 2S of the hatband 25 of insertion arm 22.Rotating part 21 makes pin 26 slide along guide groove 28, and two

contact surfaces

23 and 24 are pressed mutually.With the end of guide groove 28, pin 26 is fixed in the end of the guide groove among Fig. 3, thereby keeps two

contact surfaces

23 and 24 to compress.

In Fig. 4, show the grafting of 32 of nozzle arm part 31 and link arms.The plug 36 of nozzle arm part 31 is introduced in the socket 35 of link arm 32, contacted with each other up to contact surface 33 and 34.The surface 37 of plug 36 and socket 35 inboards scribble the material of high skin friction resistance.Because this high skin friction resistance, plug 36 and socket 35 only can be used external force, and its locked position from Fig. 4 is loosened, and for example use this two assembly of external force traction.
