Description
Technical field
The present invention relates to 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 forms, by repeatedly each side edge part of two cord plys being engaged to lengthen, thereby as uses such as the casing plies of tire.
And, there are overlapping mode, zipper joint mode, the banjo fixing butt jointing mode (patent documentation 1) of following expression as the representation mode of this joint.
Overlapping mode is by by the side edge part of two cord plys overlapping overlapping portion that forms fully each other, and from this overlapping portion entirety of crimping simultaneously engages up and down mode.As long as crimping overlapping portion just can complete so easy mode of joint, therefore have the equipment without labyrinth owing to being, higher feature of production efficiency, is mainly used in the cord ply of the less passenger car tire of rubber mass between thinner thickness, cord.
Zipper joint mode is by by each side edge part of two cord plys slightly overlapping overlapping portion that forms each other, and from Yi Fang end, this overlapping portion towards the opposing party's end the mode mode that crimping engages in order with closed zipper.Its compared with overlapping mode because overlapping portion is less, for example can engage by overlapping 1～2mm, therefore the cord ply after joint can reduce connector portions, obtains the feature of the tire of the uniform TFV of superior high speed (Tractive force variation).The cord ply of the lorry visitor tire for vehicles that therefore zipper joint mode is mainly used in that thickness is thicker, rubber mass between cord is more.
Banjo fixing butt jointing mode is by the end face of the side edge part of two cord plys is docked each other, and the mode of pressing to engage in abutting direction.Because without overlapping portion is set, so it is same with zipper joint mode, there is the cord ply center tap portion that can reduce after joint, obtain the feature of the tire of the superior uniform TFV of high speed.Therefore, connect the steel-cord ply of joint style for the more lorry visitor tire for vehicles of rubber mass.
Patent documentation 1: TOHKEMY 2001-105508 communique
But in order to engage reliably, therefore overlapping portion is larger in overlapping mode, for example, need to be set as 4～8mm.Consequently, the cord ply center tap portion after joint increases, and the uniform TFV of high speed of tire is worsened, and produces the problems such as vibration.Therefore, cannot adopt overlapping mode for the joint of the cord ply of specific tires.
Reduce overlapping portion in order to prevent the baneful influence at a high speed uniform TFV, for example, be set as 1～2mm, if carry out crimping same, likely produce the local position that there is no cord, occur the position that bond strength is weak.
On the other hand, in zipper joint mode, overlapping portion is less compared with overlapping mode, in order to engage reliably, and the rubber mass more than needing to a certain degree between cord.Therefore, for used thickness, compared with for the joint of the cord ply of the passenger car tire of thin cord ply, it is difficult adopting zipper joint mode.
In addition, due to the job requirements that less overlapping portion is engaged towards the opposing party's end in order from a side end is had to higher precision, the device of therefore comparing with overlapping mode is labyrinth, and must carry out trickle adjustment to device.In addition, the maintenance times of device and the fault of generation are also more, and therefore existence significantly reduces the problem of production efficiency compared with overlapping mode.
In addition, this overlapping mode and zipper joint mode, due to cannot dual-purpose one table apparatus, in order to take into account two kinds of modes, just must arrange the device corresponding with each mode, therefore has the problem that needs larger space and cause cost raising.
And, in docking mode, due to overlapping portion not being set, therefore same with 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 cord ply of the passenger car tire of the cord ply that used thickness is thinner.
In addition, due to by the end face of the side edge part of two cord plys each other to fetching the higher precision of job requirements of joint, there is the problem that production efficiency is lower therefore equally with zipper joint mode.

Detailed description of the invention
Below, to describing for implementing preferred forms of the present invention.In addition, the present invention is not limited to following mode, in scope identical with the present invention or that be equal to, can apply various changes to following embodiment.
First, based on Fig. 1, the substance of the joint method the present invention relates to and overlapping mode are in the past carried out to comparative illustration.Fig. 1 (a) is overlapping mode in the past, and Fig. 1 (b) is the side view that represents to use the appearance of in the joint method situation the present invention relates to, two cord plys 1,2 being pressed.Here, Fig. 1 should be readily appreciated that schematic diagram of the present invention, changes aptly to represent the size (Fig. 2 later figure too) of each portion according to actual cord ply.
As shown in Fig. 1 (a), in overlapping mode, the side edge part of the side edge part of cord ply 1 and cord ply 2 is overlapping on a large scale.And overlapping part is pressed parts and presses to hollow arrow direction, by integrated the half finished rubber of lap, two cord plys are engaged thus.
On the other hand, as shown in Fig. 1 (b), in the joint method the present invention relates to, the side edge part of the side edge part of cord ply 1 and cord ply 2 is slightly overlapping, and under the state being pressed, be pressed parts and pressure-containing parts to thin-line arrow direction from laterally pressing lap is applied to shearing force, by fully integratedization of half finished rubber of lap by cord ply firm engagement.
Like this, the joint method the present invention relates to is different from overlapping mode in the past, not only direction is pressed but also from transverse direction, lap is applied to shearing force simultaneously up and down, therefore can not form larger overlapping portion, for example the width that engages needed side edge part is set as to 1～2mm, can engage reliably, therefore can expect not make the uniform TFV of high speed of tire to worsen.
Then the major part of, utilizing the engagement device of Fig. 2 to the tire cord layer the present invention relates to i.e. first unit of exerting pressure, unit and second of exerting pressure describes.
Fig. 2 represents 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 up of opposed the first press member 7 and the first pressure-containing parts 4.In addition, second exert pressure unit by opposed second exert pressure 6 and second pressure-containing parts 3 form.
And the second press member 6 is configured to by the fulcrum being positioned at outside the figure on top of the first press member 7 is opened and closed as the rotation at center.Equally, the second pressure-containing parts 3 is also configured to by rotation and opens and closes with respect to the first pressure-containing parts 4.
In addition, engagement claw 10b is set in the first press member 7, engagement claw 10a is set in the second press member 6, engagement claw 9b is set on the first pressure-containing parts 4, and engagement claw 9a is set on the second pressure-containing parts 3, and engagement claw 10a, 10b and 9a, 9b are opposite.
And, on the first pressure-containing parts 4, be provided with spring 5, spring 5 to the top of the first pressure-containing parts 4 towards the upside application of force.By spring 5 is set, thereby produce step t between the upper end of the first pressure-containing parts 4 and the upper end of the 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 metal member made that hardness is higher.Particularly, preferably Vickers hardness (Hv) is more than 200 metal, for example iron parts more than S45C.
The size of the each engaged claw preferably width of bottom is 5～15mm, and the width of leading section is bottom width 40～100%, highly preferably 100～150% of bottom width.If bottom width exceedes 15mm, be difficult to engage equably, likely produce part and engage not good.In addition, if be less than 5mm, because the number of engaged claw increases, the machining that therefore engagement claw is set becomes difficulty, and processing cost is improved.Fig. 3 represents to engage an example of claw concrete shape with top view.
Next, utilize Fig. 4～Fig. 8 to having used the joint method of engagement device of the tire cord layer the present invention relates to, point three following steps describe particularly.
Fig. 4 is the figure that the joint method of the tire cord layer the present invention relates to is described, utilizes top view and side view to represent the unit of respectively exerting pressure in engaging process, the specifically running-active status of each press member and each pressure-containing parts.
In addition, Fig. 5～Fig. 8 represents each press member in engaging process and and the running-active status of pressure-containing parts with stereogram.
(1) step 1:
In step 1, explanation loads two cord plys in the process of the end face of pressure-containing parts.As shown in Fig. 4 (a), each press member rises and separates with opposed each pressure-containing parts.And, by the second press member 6 and the second pressure-containing parts 3 are rotated slightly, open each press member bottom and each pressure-containing parts upper end each other each other.In addition, on the first pressure-containing parts 4, be provided with spring 5, spring 5 to the top of the first pressure-containing parts 4 towards the upside application of force.
First, by making the side edge part of Rack be projected into the second pressure-containing parts 3 sides, the first cord ply 1 is loaded in the end face of the first pressure-containing parts 4.
Then, although move on the second cord ply 2 right side from drawing on the end face of the second pressure-containing parts 3, but because the upper end of the upper end at the first pressure-containing parts 4 and the second pressure-containing parts 3 is by being provided with above-mentioned step by the spring 5 that is arranged at the first pressure-containing parts 4, therefore moving second cord ply 2 of coming in can not collide with the first cord ply, and the length that movement specifies below the first cord ply 1, in the time encountering the stage portion of the first pressure-containing parts 4, stop, and loaded in the end face of the second pressure-containing parts.Like this, form the overlapping portion of the side edge part outstanding with the first cord ply.By step as described above is set, just can form accurately overlapping portion.Fig. 5 represents the stereogram of the situation of step 1.
(2) step 2:
In step 2, explanation declines the first press member 7 and the second press member 6 and above-mentioned overlapping portion is applied to the process (with reference to Fig. 4 (b)) of pressing force.For the first press member 7 declining and the second press member 6, first as shown in Figure 6, the first press member 7 contacts with the first cord ply loading in the first pressure-containing parts 4 end faces.Now, owing to being provided with step at the first pressure-containing parts 4 and the second pressure-containing parts 3, therefore the second press member 6 does not also contact with the second cord ply 2 loading in the second pressure-containing parts 3 end faces.In addition, as the concrete unit of exerting pressure, it for example can use cylinder to press.
If further pressed, as shown in Figure 7, the end face of the first pressure-containing parts 4 that is projected into top because of spring 5 application of forces decline that is pressed.Then, the end of the engagement claw 10a downside of the second press member 6, contacts with the second cord ply 2 loading in the end face of the second pressure-containing parts 3.Afterwards, owing to further making the first press member 7 and the second press member 6 decline, therefore the first cord ply 1 is fixed reliably, and the overlapping portion of two cord plys pressed by the second press member 6 and the second pressure-containing parts 3, thereby is crimped on above-below direction.
(3) step 3:
In step 3, the process (with reference to Fig. 4 (c)) of shearing force is further bestowed in explanation to the overlapping portion of two cord plys.In step 2, the first cord ply is by the first press member 7 and the first pressure-containing parts 4 and fixed reliably, the overlapping portion of two cord plys is under the state of being pressed by the second press member 6 and the second pressure-containing parts 3, the second press member 6 and the second pressure-containing parts 3 are rotated, make each engagement claw move to first cell side of exerting pressure, opposed engagement claw is engaged with each other.Fig. 8 represents the stereogram after engagement.
Now, the overlapping portion of two cord plys is applied to the pressing force of above-below direction by the second press member 6 and the second pressure-containing parts 3, and be applied in the shearing force of transverse direction.Now, particularly the first cord ply described above is fixed reliably.On the other hand, because the overlapping portion of two cord plys is pressed by the front end of each engagement claw of the second press member 6 and the second pressure-containing parts 3, therefore the 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 clamp half finished rubber and apply larger shearing force.Consequently, can make the overlapping portion of cord ply be easy to integratedly firmly engage.
In addition, for the ease of understanding, the STA representation engagement claw to engage completely in Fig. 4 (c) and Fig. 8, but in a part for engagement, clamp and have rubber in fact as mentioned above.
Preferably with on the bearing surface of each cord ply that engages claw, implement annular knurl processing.By implementing annular knurl processing, thereby can make the first cord ply not slide and fix reliably the first cord ply in the time of the engagement of engagement claw, also do not slide in two cord ply overlapping portions the second press member 6 and the second pressure-containing parts 3, thereby can apply shearing force to transverse direction reliably.Particularly owing to easily producing and sliding on the bearing surface at the first press member 7 and the first pressure-containing parts 4 and cord ply 1, therefore preferably at least in the first press member 7 and the engagement claw of the first pressure-containing parts 4 and the processing of the bearing surface of cord ply enforcement annular knurl, preferably annular knurl line is more than five.
So, not only apply pressing force at above-below direction in the overlapping portion of two cord plys, and apply shearing force from transverse direction, therefore for rubber thickness compared with thin car with for cord ply, even if the width of overlapping portion is reduced to 1～2mm, also can engage reliably.And, can provide by the cord ply engaging in zipper joint mode and form, have the tire that does not make the deteriorated TFV of the uniform TFV of high speed of tire.
And joint method of the present invention is different from the mode that zipper joint mode engages in order from end like that, owing to being the method that the entirety of overlapping portion is engaged 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 heat the side edge part of cord ply while engage, because the half finished rubber of overlapping portion is softening, therefore further integrated joint more firmly.In this case, preferably heating-up temperature is 60～120 DEG C, particularly, for example, carries out heating in 1～2 second with about 100 DEG C while engages, thereby can bring into play fully the effect of heating.
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 the shape that Fig. 3 represents and the engagement device of pressure-containing parts, the each lap (width of overlapping portion) representing with table 1 according to the joint method of the invention described above carries out the joint of two cord plys (size: width 300mm × thickness 1.0mm), and has measured the pressure that acts on junction surface.
Comparative example:
The engagement device that uses as a comparative example overlapping mode in the past, engages by overlapping mode, and has measured the pressure that acts on junction surface.
The result of measuring is, is 4mm and used overlapping mode in the past pressure to act on junction surface to be shown in table 1 as 100 relative value at lap.
In addition, the pressure measxurement film (the Press Kale of Fuji processed of Fuji Photo Film Co., Ltd.) that accommodates the microcapsules of colour coupler and be coated with developer is sandwiched to pressure-producing part and pressure-containing parts, and the pressure that acts on junction surface when the pressing force of above-below direction is 0.4MPa is measured.Measurement result is shown in Fig. 9.
Table 1:
The result representing according to Fig. 1, in the situation that lap is 4mm, in joint method of the present invention, in the situation of overlapping mode in the past, applied pressure, also act on shearing force, therefore the known pressure of approximately 1.5 times that junction surface effect is had to overlapping mode in the past.
And in the situation that lap is 1mm, the pressure that acts on junction surface in overlapping mode is in the past 81, reduces approximately 20% compared with the situation that is 4mm with lap, thereby have the possibility that can not obtain sufficient engagement state.On the other hand, in joint method of the present invention, can obtain the pressure of approximately large 1.2 times of pressure while being 4mm than overlapping mode lap in the past.This shows, in the situation that using joint method of the present invention, even if lap is reduced to 1mm, also can become while being 4mm than the lap of overlapping mode in the past more firmly engagement state.
In addition, as shown in Figure 9, known the in the situation that of joint method of the present invention, can act on substantially equably in overlapping portion larger pressing force, thereby obtain fully firmly engagement state.
So, according to the present invention, also can obtain sufficient engaging force even if reduce lap.And joint method of the present invention, effective especially when need to make as far as possible junction surface width owing to likely producing the mesh of cord in the time engaging be the joint of minimum transverse cuts cord.
