Description
Technical field
The present invention relates to a kind of conveyer chain, or rather, relate to the slip ability that a kind of energy promotion transmits the outside face of object in the above, reduce the conveyer chain that is damaged by the object basal surface that slided simultaneously.
Background technology
In the conveyer system of producing aluminium pot, glass bottle, PET (polyethylene terephthalate) bottle and other objects continuously, conveyer chain is used to transmit the mechanism of this type objects more, use this system of conveyer chain to be included in its transmission that chien shih is transmitted that logistics stops and each step of their marshallings, such make logistics stop with each step that they are come into line in each object must be on conveyer chain relative it slide.
Promote a chain that example is to use resin to do of the slip ability of such conveyer chain outside face.So far, used polyformaldehyde resin, polyethers-imide resin or fluorine resin are as the link material of conveyer resin chain.But such plastic links is easy to wearing and tearing owing to hardness is very poor, thereby their service life is very short.If in order to improve their hardness, add graphite in such plastic links, their dynamic friction coefficient will reduce.But added graphite becomes dust owing to friction can drop out, this has just produced problem: thus dust can penetrate into the debase that the inside that is transmitted object and finish coat make this object, also has dust that electronic circuit near the device is also had bad influence.
In the defeated biography machine system manufacturing line of reality, the outside face of conveyer chain is used lubricant as water or soap water, so that promote their slip ability.Because its outside face that transmits object of conventional conveyer chain is flat (seeing Japanese utility model application publication number No57-49812), its lower surface was to be close on the outside face of conveyer chain when object transmitted but in general.Therefore, even on the outside face of conveyer chain, use such lubricant so that promote their slip ability, this lubricant also is transmitted the lower surface of object to be got rid of from the outside face of conveyer chain, and the result is the slip ability of conveyer chain outside face or not enough.
If with relative not only hard but also thin impurity, adhere on the outside face of conveyer chain as glass powder or metal powder, can cause another kind of problem so again: the bottom of the object that is transmitted on conveyer chain can be by very thin impurity scratch.
Therefore target of the present invention provides a kind of conveyer chain, and it can promote to transmit in the above the slip ability of the outside face of object, the damage of the object basal surface that reduces simultaneously to be slided.
Of the present invention open
The invention provides a kind of conveyer chain, it comprises one group of chain link that is connected to each other circlewise by this way, the front end of a chain link connects pin and contiguous movable connection of chain link rear end by one, it is characterized in that the object that will transmit is placed on the outside face of each top chain link, the dynamic friction coefficient that measures under following test condition is less than 0.3, test condition is that the object of aluminum slides on the outside face of each chain link, and its pressure is 5kg/cm
2(kg/cm), the circumferential velocity of chain are 20m/min (meter/minute).
Under this condition, when when the transmission that stops object and/or in the conveyor line centre object being come into line, the outside face that has improved conveyer chain of the present invention has reduced by the damage of slip object basal surface simultaneously with respect to the slip ability that transmits object above it.
As an embodiment of conveyer chain of the present invention, transmit the outside face of each chain link of object in the above and form by many little ribs and groove.
Many little rib that forms on the chain link outside face and groove have reduced the area with the contacted outside face of basal surface that is transmitted object, thereby have reduced the friction drag between them, improve the slip ability that each chain link outside face is transmitted object relatively.In addition, even the thin impurity of high hardness is bonded on the outside face of conveyer chain of the present invention as glass powder and metal powder, the basal surface that is transmitted object is pushed into them in the groove that forms on each chain link, thereby the basal surface that prevents object is abraded by them.
Be preferably on the outside face of conveyer chain of the present invention, promptly be transmitted object and be placed on a kind of lubricant of use on the top outside face.This lubricant will be maintained in the groove that forms on the chain link, bit by bit little by little be discharged into the outside face of conveyer chain, can improve the slip ability of conveyer chain outside face so widely.Because lubricant remains in the groove and is discharged into outside face gradually, just need can only not use a spot of lubricant well to conveyer chain of the present invention in addition as in the conveyer chain of routine, using any a large amount of lubricant to carry out continuous lubrication.
As another embodiment, each chain link of conveyer chain of the present invention is to make with a kind of complex that contains polyamide-imide resin and fluorine resin.
The dynamic friction coefficient of the conveyer chain outside face of being made up of such resin chain link greatly reduces, and can make its critical pressure-speed (PV) value optimization in addition.Also have, because this resin chain link has higher creep impedance, the conveyer chain that is made of these chain links neither can extend can be not loose yet.Therefore, it does not need artificially control conveyer chain to become loose to prevent it, can save the labour power of safeguarding conveyer chain.
Also have, the present invention also provides the use of above-mentioned conveyer chain, it is characterized in that sliding at the object that is transmitted on conveyer chain outside face with respect to the conveyer chain that contacts with this object at least a portion of the outside face of conveyer chain.
Conveyer chain of the present invention can demonstrate its various features especially in this application, and prevents that the basal surface with the object that slides that is transmitted is scratched in the above.

Describe these chains below in detail.
At first, describe the chain of being made up of such chain link in detail, each chain link forms many little ribs and groove on its outer surface, is transmitted on the outside face that object is placed on them.For can this class chain easier to understand, please refer to accompanying drawing.
Fig. 1 is a transparent view, and part shows an embodiment of conveyer chain of the present invention has many little ribs and groove on its outside face, is transmitted on the outside face that object is placed on it.1 is a chain link in the drawings, is transmitted on the outside face that object is placed on it.Many such chain links 1 are interconnected into a line circlewise and constitute conveyer chain 10, and it moves in the direction of arrow F.
Each chain link 1 has a joint 1a at the horizontal center of its front end, in the both sides of rear end forked element 1b, 1b is arranged.Joint 1a between 1b and 1b with the forked element 1b of adjacent link 1,1b links to each other.These joints 1a and 1b install pin-and- hole 2a and 2b separately, and pin-and-hole is horizontally through, and a metallic pin (not shown) is inserted in this hole, can relative motion by the chain link that pin is adjacent.Need not explanation, in these chain links 1, forked element 1b, 1b can be at the front ends of each chain link, and center sub 1a can be in its rear end.Each chain link 1 is transmitted on the whole outer surface of object in placement, and the little rib 3 of many length and the groove 4 of many length are arranged, and their are parallel to each other alternately to form, and stretches along sense of motion (being the direction of arrow F).Hope is transmitted in placement on the whole outer surface of each chain link of object and forms these ribs and groove, but always must not form these ribs and groove on whole outer surface.According to the type that on conveyer chain, is transmitted object, can form little rib and groove on the outside face top of each chain link.
As Fig. 2, the profile of the cross-sectional plane of each little rib 3 is trapezoidal, and the profile of the cross-sectional plane of each groove 4 is trapezoidal, and therefore the sidewall of little rib is a bevelled.Or rather, the profile of each little rib 3 cross-sectional plane is taper towards the outside face of chain link, broadens and the profile of each groove 4 cross-sectional plane is outside faces towards chain link.With the profile of so little rib and groove, make the horizontal undulate of the outside face of this chain link at it.
The shape of these ribs and groove is not special the qualification, as long as these ribs and groove can constitute a kind of structure that can reduce the outside face of chain link and will be placed on the area of contact between the top object.But preferably each chain link outside face vertically on alternately form little rib and many grooves of many length.More preferably these little ribs and groove alternately form, and the sense of motion stretching, extension along conveyer chain parallel to each other.Use such structure, conveyer chain can carry the object that will transmit.In addition, each chain link can have many elongated slots along the sense of motion of chain link stretch and many elongated slots along the lateral extent of direction of relative movement, and the independently little rib that surrounds of these grooves of some usefulness.Some so in this case independently little ribs layout that can chessboard meets at right angles like that, but also toothing is arranged, perhaps even can be arranged to random state.Under any circumstance, wish that the long so little rib and the profile of independently little each cross-sectional plane of rib are trapezoidal basically, and the profile of the cross-sectional plane of each groove is trapezoidal basically.The height of wishing each rib simultaneously is identical substantially.
With regard to the relation between long little rib 3 and the adjacent groove 4, the spacing P that wishes to be clipped in the rib 3 between the adjacent slot 4 is preferably in 0.8 to 1.5mm between 0.5 to 2.0 millimeter (mm), and the depth D of each groove 4 is 0.2 to 2.0mm, preferably 0.5 to 1.5mm.Identical data may be used on rib independently and surround relation between the groove of this rib.The spacing that is rib wishes that 0.5 to 2.0mm more preferably 0.8 to 1.5mm, and the degree of depth of each groove is wished 0.2 to 2.0mm, more preferably 0.5 to 1.5mm.
Use little rib 3 such on each chain link outside face and groove 4, reduce the outside face of the conveyer chain formed by such chain link and be placed on area of contact between the top object, thereby having reduced friction drag between chain and the object, the result has improved the slip ability that the conveyer chain outside face is placed on top object relatively.In addition, even there is hard small impurities to be bonded on the outside face of conveyer chain, is placed on top object impurity will be fallen in the groove 4.Therefore, the basal surface of the object that transmit will can not abraded by such impurity.In the present invention, the material of this chain link is unspecial to be limited, as long as the dynamic friction coefficient of the outside face of each chain link own can be within restricted portion.Therefore, can use any known for example metal, resin and stupalith, but resin preferably.Use also unspecial qualification of type of resin in the present invention.Available is various thermoplastic base resins and thermosetting resin, comprising for example polyacetal resin, and polyethers-imide resin, polyamide-imide resin, polyimide resin, and liquid crystal polymer are as liquid crystal polyester.
If wish, in these resins, can add fluorine resin, as polytetrafluoroethylene, tetrafluoraoethylene-hexafluoropropylene copolymer, poly-trichlorine PVF, and tetrafluoroethylene-Gao fluoroalkyl vinyl ether copolymers and lubricant be not as long as such additive influences each target of the present invention.
Material as each chain link that little rib and groove are arranged on its outer surface, each complex that most preferably comprises polyamide-imide resin and fluorine resin, wherein the best percentage by weight of the content of fluorine resin is 0.3 to 40%, and more preferably percentage by weight is 5 to 30%.
The material of metal pin is unspecial yet to be limited, and for example can comprise iron copper, corrosion-resistant steel, resin and pottery.
Preferably also on the outer face surface that is transmitted the chain link of object above being placed on, use a kind of lubricant.The preferred example of each lubricant is water and soap water.
Be added to that lubricant on the chain link outside face will keep thereon and in the groove that forms, and be discharged into gradually on the outside face topped they.Even when only having a small amount of such lubricant to be added to outside face, just can improve the slip ability of each chain link outside face therefore.

Because polyamide-imide resin has remarkable tear resistance, its life-span of chain of being made by such resin is than other resins, will grow as the life-span of polyethers-imide resin or polyformaldehyde resin made chaining.In general, conveyer chain of the present invention is used for coming two or more sprocket wheels under quite high tension force.Because polyamide-imide resin has outstanding creep resistance, the conveyer chain of being made up of it neither can extend, and can be not loose.Therefore do not need this conveyer chain of manual control, become loose so that prevent it, and can save the labour who safeguards conveyer chain.
Can use any known polyamide-imide resin in the present invention, comprise the various resins of selling on the market, as " the TI poly-mer " produced by Toure (Toray) industrial.
Used in the present invention fluorine resin comprises for example polytetrafluoroethylene, tetrafluoraoethylene-hexafluoropropylene copolymer, poly-trichlorine PVF, and tetrafluoroethylene-Gao fluoroalkyl vinyl ether copolymers.In these, polytetrafluoroethylene (PTFE) preferably.Best its percentage by weight of the amount of added fluorine resin is 0.3 to 40%, and more preferably the percentage by weight of complex total weight is 5 to 30%.The used polyamide-imide resin of the present invention can with other combinations of thermoplastic resins, as long as additional resin does not influence effect of the present invention.
Outside face at least a portion of this chain is to be made by the resin composition that comprises polyamide-imide resin and fluorine resin, and this structure of this chain not only can reduce the dynamic friction coefficient on the outside face, and even optimization critical pressure-speed (PV) value.Therefore even without with lubricator the time, use this chain object that also can on its surface, slide smoothly.
Make with the complex that comprises polyamide-imide resin and fluorine resin that the method for chain link of this chain is unspecial to be limited.For example, applicable method has injection molded directly to produce the method for chain link, and also having a kind of method is to make runic by extrusion molding and compression molding forming earlier, cuts subsequently with fine limit work to make runic become the chain link of required form.
In the present invention, be transmitted the outside face that object will be placed on top chain link at least and make, thereby improved the slip ability of chain link outside face by above-mentioned resin composition.But in order to prolong the service life of chain link, save the labour who safeguards chain link, help the injection molded of chain link and simplify the structure of chain link, wish chain link whole be to make by resin composition.
In addition, for the physical property of each chain link of further improving chain,, wish that chain link heat-treats after being shaped as resistance to effect of heat and intensity.This be because if they through bakingout process, the shaping article of being made by the complex that comprises polyamide-imide resin and fluorine resin can have improved hardness, intensity and resistance to effect of heat.Therefore the chain of being made up of heat treated like this chain link can have the much longer life-span.The chain link of chain of the present invention is produced by injection molded, and they are generally all through bakingout process after injection molded.If chain link is produced by extrusion molding or compression moulding, wish that the entity of shaping is heat-treated, cut into chain link then.Do not do but do not limit to like this.Both can cut into chain link to the entity that is shaped earlier, then the chain link of such cutting be heat-treated, perhaps also can before cutting step and afterwards, all heat-treat.
Heat treatment can be carried out under 200 ℃ or higher temperature, is preferably under 150 ℃ or the higher temperature to carry out.Heat treatment period can be 12 hours or longer, preferably 24 hours or longer.
