Description
Technical field
The present invention relates to the engagement device and the joint method of tire cord layer.
Background technology
Cover parallel by half finished rubber and show the cord ply that the cord arrange body of cord constitutes, extend by repeatedly each side edge parts of two cord plys being engaged, thereby as the uses such as casing ply of tire.
And, overlapping mode, zipper joint mode, the banjo fixing butt jointing mode (patent documentation 1) of following expression are arranged as the representation mode of this joint.
Overlapping mode is by forming overlapping portion with the side edge part of two cord plys is overlapping fully each other, and from this overlapping mode that integral body engages of crimping simultaneously up and down.Owing to be as long as overlapping of crimping just can be finished so easy mode of joint, therefore have the equipment that need not labyrinth, the characteristics that production efficiency is higher are mainly used in the cord ply of the less car usefulness tire of rubber mass between thinner thickness, cord.
The zipper joint mode is by forming overlapping portion with each side edge part of two cord plys is overlapping slightly each other, and from this overlapping side's end towards the opposing party's end in the mode of the closed slide fastener mode that engages of crimping in order.Its compare with overlapping mode since overlapping less, for example can engage by overlapping 1～2mm, therefore the cord ply behind joint can reduce connector portions, obtains the characteristics of the tire of the superior uniform TFV of high speed (Tractive force variation).Therefore the lorry passenger vehicle that the zipper joint mode is mainly used in that thickness is thicker, the rubber mass between cord is more is with the cord ply of tire.
The banjo fixing butt jointing mode is to dock each other by the end face with the side edge part of two cord plys, and pushes the mode that engages in the butt joint direction.Because need not to be provided with overlapping portion, so itself and zipper joint mode are same, have the cord ply center tap portion after can reducing to engage, obtain the characteristics of the tire of the superior uniform TFV of high speed.Therefore, connect joint style and be used for the steel-cord ply of the more lorry passenger vehicle of rubber mass with tire.
Patent documentation 1: TOHKEMY 2001-105508 communique
Yet, in overlapping mode in order to engage reliably, therefore overlapping bigger, for example need to be set at 4～8mm.Consequently, the cord ply center tap portion behind joint increases, and the uniform TFV of high speed of tire is worsened, and produces problems such as vibration.Therefore, the joint for the cord ply of specific tires can't adopt overlapping mode.
In order to prevent that the baneful influence of TFV is at a high speed uniformly reduced overlapping portion, for example be set at 1～2mm, if carry out crimping same, then might produce the position that the part does not have cord, the more weak position of bond strength appears.
On the other hand, in the zipper joint mode, compare with overlapping mode overlapping less, in order to engage the rubber mass more than needing to a certain degree between cord reliably.Therefore, the car of thin cord ply is with the joint of the cord ply of tire for for used thickness, and employing zipper joint mode is difficult.
In addition, because to overlapping less job requirements that engages in order towards the opposing party's end from a side end had higher precision, the device of therefore comparing with overlapping mode is a labyrinth, and must carry out trickle adjustment to device.In addition, the maintenance times of device and the fault of generation are also more, therefore compare the problem that existence significantly reduces production efficiency with overlapping mode.
In addition, this overlapping mode and zipper joint mode, because can't dual-purpose one table apparatus, in order to take into account dual mode, just the device corresponding with each mode must be set, therefore there is the problem that needs bigger space and cause the cost raising.
And, in docking mode, because overlapping portion is not set, therefore same with the zipper joint mode, rubber mass in order to engage reliably more than needing to a certain degree between cord, thereby should be difficult to use in the joint of car with the cord ply of tire of used thickness than thin cord ply.
In addition, owing to, therefore have the lower problem of production efficiency equally with the zipper joint mode to higher to the job requirements that the fetches joint each other precision of end face with the side edge part of two cord plys.

The specific embodiment
Below, describe being used to implement preferred forms of the present invention.In addition, the present invention is not limited to following mode, can apply various changes to following embodiment in or the scope that is equal to identical with the present invention.
At first, based on Fig. 1 the substance of the joint method that the present invention relates to and in the past overlapping mode are compared explanation.Fig. 1 (a) is an overlapping mode in the past, and Fig. 1 (b) is the side view that the appearance of under the joint method situation that the present invention relates to two cord plys 1,2 being pushed is used in expression.Here, Fig. 1 should be readily appreciated that schematic diagram of the present invention, changes the size of representing each one (Fig. 2 later figure too) aptly according to the cord ply of reality.
Shown in Fig. 1 (a), the side edge part of the side edge part of cord ply 1 and cord ply 2 is overlapping on a large scale in overlapping mode.And overlapping part is pressed parts and pushes to the hollow arrow direction, and is thus that the half finished rubber of lap is integrated with two cord plys joints.
On the other hand, shown in Fig. 1 (b), the side edge part of the side edge part of cord ply 1 and cord ply 2 is overlapping slightly in the joint method that the present invention relates to, and under the state that is pressed, be pressed parts and pressure-containing parts and from laterally pushing lap applied shearing force to the thin-line arrow direction, with fully integratedization of half finished rubber of lap with the cord ply firm engagement.
Like this, the joint method that the present invention relates to is different with overlapping mode in the past, not only direction is pushed but also from transverse direction lap is applied shearing force simultaneously up and down, therefore can not form bigger overlapping portion, the width that for example will engage needed side edge part is set at 1～2mm, can engage reliably, therefore can expect not make the uniform TFV of high speed of tire to worsen.
Then, utilize Fig. 2 that the major part of the engagement device of the tire cord layer that the present invention relates to is promptly described first unit of exerting pressure, unit and second of exerting pressure.
Fig. 2 is expression first the exert pressure stereogram of unit of unit and second of exerting pressure.As shown in Figure 2, first unit of exerting pressure is made of opposed first press member 7 and first pressure-containing parts 4.In addition, second unit of exerting pressure is made of opposed second 6 and second pressure-containing parts 3 of exerting pressure.
And second press member 6 constitutes by the rotation of the fulcrum outside the figure on the top that will be positioned at first press member 7 as the center and opens and closes.Equally, second pressure-containing parts 3 also constitutes by rotation and opens and closes with respect to first pressure-containing parts 4.
In addition, engagement claw 10b is set on first press member 7, engagement claw 10a is set on second press member 6, engagement claw 9b is set on first pressure-containing parts 4, and engagement claw 9a is set on second pressure-containing parts 3, and engagement claw 10a, 10b and 9a, 9b are mutually opposed.
And first pressure-containing parts 4 is provided with spring 5, and the top of 5 pairs first pressure-containing parts 4 of spring is towards the upside application of force.By spring 5 is set, thereby produce step t between the upper end of the upper end of first pressure-containing parts 4 and second pressure-containing parts 3, step t is the step more bigger than the thickness of one piece of cord ply.
Each press member and pressure-containing parts are preferably the higher metal member made of hardness.Particularly, preferred Vickers hardness (Hv) is the metal more than 200, for example the above iron parts of S45C.
The width of the preferred bottom of size of each engaged claw is 5～15mm, and the width of leading section is 40～100% of a bottom width, highly preferably 100～150% of bottom width.If bottom width surpasses 15mm, then be difficult to mesh equably, might produce the part and mesh not good.In addition, if less than 5mm, then because the number of engaged claw increases, the machining that therefore the engagement claw is set becomes difficult, and processing cost is improved.Fig. 3 represents to mesh an example of the concrete shape of claw with vertical view.
Next, utilize the joint method of Fig. 4～Fig. 8, divide three following steps to describe particularly the engagement device that used the tire cord layer that the present invention relates to.
Fig. 4 is the figure of the joint method of the tire cord layer that the present invention relates to of explanation, and utilizing vertical view and side view to represent the unit of respectively exerting pressure in the engaging process particularly is the running-active status of each press member and each pressure-containing parts.
In addition, Fig. 5～Fig. 8 represents each press member and and the running-active status of pressure-containing parts in the engaging process with stereogram.
(1) step 1:
Illustrate two cord ply mountings in the process of the end face of pressure-containing parts in the step 1.Shown in Fig. 4 (a), each press member rises and separates with opposed each pressure-containing parts.And, rotate slightly by making second press member 6 and second pressure-containing parts 3, open each press member bottom each other and each pressure-containing parts upper end each other.In addition, first pressure-containing parts 4 is provided with spring 5, and the top of 5 pairs first pressure-containing parts 4 of spring is towards the upside application of force.
At first, by the side edge part that makes Rack be projected into second pressure-containing parts, 3 sides with first cord ply, 1 mounting in the end face of first pressure-containing parts 4.
Then, though move on second cord ply 2 right side from drawing on the end face of second pressure-containing parts 3, yet since in the upper end of the upper end of first pressure-containing parts 4 and second pressure-containing parts 3 by being provided with above-mentioned step by the spring 5 that is arranged at first pressure-containing parts 4, therefore second cord ply 2 that moves into can not collide with first cord ply, and below first cord ply 1 length of mobile regulation, when running into the stage portion of first pressure-containing parts 4, stop, and by the end face of mounting in second pressure-containing parts.Like this, form the overlapping portion of the side edge part of giving prominence to first cord ply.By step as described above is set, just can form overlapping portion accurately.Fig. 5 represents the stereogram of the situation of step 1.
(2) step 2:
The process (with reference to Fig. 4 (b)) that explanation makes first press member 7 and 6 declines of second press member come above-mentioned overlapping portion is applied pressing force in the step 2.For first press member 7 that descends and second press member 6, at first as shown in Figure 6, first press member 7 contacts with first cord ply of mounting in first pressure-containing parts, 4 end faces.At this moment, owing to be provided with step at first pressure-containing parts 4 and second pressure-containing parts 3, therefore second press member 6 does not also contact with second cord ply 2 of mounting in second pressure-containing parts, 3 end faces.In addition, as the concrete unit of exerting pressure, it for example can use cylinder to push.
If further push, as shown in Figure 7, the end face of first pressure-containing parts 4 that is projected into the top because of spring 5 application of forces decline that is pressed.Then, the end of the engagement claw 10a downside of second press member 6 contacts with second cord ply 2 of mounting in the end face of second pressure-containing parts 3.Afterwards, because first press member 7 and second press member 6 are descended, therefore first cord ply 1 is fixed reliably, and overlapping of two cord plys pushed by second press member 6 and second pressure-containing parts 3, thereby is crimped on above-below direction.
(3) step 3:
Explanation is to overlapping the process (with reference to Fig. 4 (c)) of further bestowing shearing force of two cord plys in the step 3.First cord ply is by first press member 7 and first pressure-containing parts 4 and fixed reliably in the step 2, the overlapping portion of two cord plys is under the state of being pushed by second press member 6 and second pressure-containing parts 3, second press member 6 and second pressure-containing parts 3 are rotated, make and respectively mesh claw and move to first cell side of exerting pressure, opposed engagement claw is engaged with each other.Stereogram after Fig. 8 represents to mesh.
At this moment, apply the pressing force of above-below direction by the overlapping portion of second press member 6 and 3 pairs of two cord plys of second pressure-containing parts, and be applied in the shearing force of transverse direction.At this moment, particularly as mentioned above first cord ply fixed reliably.On the other hand, because overlapping the front end that respectively meshes claw by second press member 6 and second pressure-containing parts 3 of two cord plys pushed, therefore first cord ply is inactive, and do not produce dislocation in the overlapping portion of two cord plys, thereby engagement claw 9a and 10a can the clamping half finished rubbers and apply bigger shearing force.Consequently, can make the overlapping portion of cord ply be easy to the integrated firm joint that carries out.
In addition, for the ease of understanding, among Fig. 4 (c) and Fig. 8 with the STA representation engagement claw of engagement fully, yet in fact as mentioned above in the part of engagement clamping rubber is arranged.
Preferably with the bearing surface of cord ply of each engagement claw on implement annular knurl processing.By implementing annular knurl processing, thereby the time first cord ply is not slided and fix first cord ply reliably in the engagement of engagement claw, do not slide in overlapping second press member 6 of two cord plys and second pressure-containing parts 3 yet, thereby can apply shearing force to transverse direction reliably.Particularly owing on the bearing surface of first press member 7 and first pressure-containing parts 4 and cord ply 1, easily produce slip, therefore preferably implement annular knurl processing at the engagement claw of first press member 7 and first pressure-containing parts 4 and the bearing surface of cord ply at least, preferred annular knurl line is more than five.
So, not only apply pressing force in the overlapping portion of two cord plys, and apply shearing force from transverse direction at above-below direction, therefore for the thin car of rubber thickness for cord ply, even the width of overlapping portion is reduced to 1～2mm, also can engage reliably.And, the tire that is constituted, had the TFV of the uniform TFV deterioration of the high speed that does not make tire by the cord ply that engages in the zipper joint mode can be provided.
And joint method of the present invention is different with the mode that the zipper joint mode engages in order from the end like that, owing to be the method that the integral body with overlapping portion engages simultaneously, therefore can keep the high efficiency roughly the same with overlapping mode.
Like this, can take into account high-quality and production efficiency according to the present invention.
In addition, in above-mentioned joint method, if while heat the side edge part of cord ply and engage, because the half finished rubber of overlapping portion is softening, therefore can further integrated joint more firmly.In this case, preferred heating-up temperature is 60～120 ℃, particularly, engages while for example carry out heating in 1～2 second with about 100 ℃, thereby can bring into play the effect of heating fully.
In addition, engagement device of the present invention is not above-mentioned joint method of the present invention, can be used in the joint of overlapping mode in the past yet.
Embodiment:
Use possesses each press member of the engagement claw with shape that Fig. 3 represents and the engagement device of pressure-containing parts, carry out two cord plys (size: joint width 300mm * thickness 1.0mm), and measured the pressure that acts on the junction surface according to the joint method of the invention described above with each lap (width of overlapping portion) of table 1 expression.
Comparative example:
Use the engagement device of overlapping mode in the past as a comparative example, engage by overlapping mode, and measured the pressure that acts on the junction surface.
The result who measures is, is to be that 100 relative value is shown in table 1 with the pressure that acts on the junction surface under 4mm and the situation of having used overlapping mode in the past at lap.
In addition, the pressure measxurement film (Fuji Photo Film Co., Ltd. system the Press Kale of Fuji) that accommodates the microcapsules of colour coupler and be coated with developer is sandwiched pressure-producing part and pressure-containing parts, and the pressure that acts on the junction surface the when pressing force of above-below direction is 0.4MPa is measured.Measurement result is shown in Fig. 9.
Table 1:
The result who represents according to Fig. 1, at lap is under the situation of 4mm, in joint method of the present invention, under the situation of in the past overlapping mode, also act on shearing force the applied pressure, therefore as can be known the junction surface effect there is about 1.5 times pressure of overlapping mode in the past.
And, be under the situation of 1mm at lap, the pressure that acts on the junction surface in overlapping mode in the past is 81, is that the situation of 4mm is compared and reduced approximately 20% with lap, thereby has the possibility that can not obtain sufficient engagement state.Relative therewith, in joint method of the present invention, the big approximately 1.2 times pressure of pressure in the time of can obtaining to be 4mm than in the past overlapping mode lap.This shows, under the situation of using joint method of the present invention, even lap is reduced to 1mm, and more firm engagement state in the time of also becoming lap than in the past overlapping mode and be 4mm.
In addition, as shown in Figure 9, under the situation of joint method of the present invention, can act on bigger pressing force substantially equably at overlapping, thereby obtain firm engagement state fully as can be known.
So,, also can obtain sufficient engaging force even reduce lap according to the present invention.And joint method of the present invention, effective especially when need make the junction surface width as far as possible owing to might produce the mesh of cord when engaging be the joint of minimum transverse cuts cord.
