Field of the Invention The present invention relates to a method and an apparatus for supplying a constant dimension of a soft strip material which can be applied to the case where the soft strip material such as a sidewall is supplied to a molding drum during a tire manufacturing process. It is about.

Description of the Related Art In the process of manufacturing a radial tire, various tire components (carcass members, beads, sidewalls, etc.) are sequentially attached to a rotatable molding drum to assemble a green case. It is common to adopt a method of assembling a green tire by deforming the toroidal shape and further attaching tire constituent parts (tread etc.).

不整合が起こることが多かった。By the way, since the sidewalls and the like are initially prepared in a state where they are formed into a strip shape and wound into a roll shape, when they are supplied to the forming drum,
It is necessary to cut the lengthwise dimension according to the circumference of the forming drum while paying out the required amount. However, at this stage, the sidewalls and the like are in a non-vulcanized state and are rich in softness, elasticity, adhesiveness and the like (hereinafter referred to as a soft strip material). Therefore, when this soft strip is cut,
Dimensional variations (especially in the longitudinal direction) and deformation of the cut surface may occur due to shrinkage, elongation or deformation due to residual stress, etc. Therefore, when this soft strip material is wound around the forming drum, the dimensions at the joint part Inconsistencies often occurred due to excess or deficiency of.

解除し軟質帯状材を繰り出すようにしている。Recently, attempts have been made to consistently automate the tire manufacturing process, and various automatic feeders for the soft strip have been proposed (for example, JP-A-58-78740). Issue, Japanese Patent Publication No. 62-69
59, etc.). In these conventional techniques, the soft strip-shaped material fed along the pedestal is made to have a state in which its tip portion slightly projects from the tip of the pedestal, and the soft strip-shaped material is fleshed at the portion corresponding to the tip portion of the pedestal. It is clamped in the thickness direction to make it immovable, and then the cradle is moved to a position where the projecting tip of the soft band-shaped material reaches the forming drum, and then the above-mentioned clamping is released to feed the soft band-shaped material. .

Is inferred. However, the end of the soft strip is a free end. This may be based on the idea that the soft material is quickly wound by the rotation of the forming drum, so that the John Into can be formed before the contraction occurs. The problem was never resolved. After all, this is a bottleneck, and it has been difficult to fully automate the tire manufacturing process.

That is, in the method for supplying a fixed size of the soft strip material according to the present invention, after feeding the soft strip material and delivering its tip to the supply destination,
The soft strip-shaped material is cut at a position where the effective feeding length of the soft strip-shaped material reaches a predetermined dimension, and the cut end portion is held by sandwiching or adsorption in the thickness direction, and the end portion is
It is characterized in that it is delivered to the supply destination in a state where the relative distance to the tip end portion which is being picked up at the supply destination remains unchanged.

特徴としている。The soft strip-shaped material that remains on the cutting treatment table in a self-adhesive state may be pulled back slightly upstream to be separated from the cutting treatment table, and then the soft strip-shaped material may be fed out. . On the other hand, in the soft strip material sizing apparatus according to the present invention, a cradle that supports and guides the feeding of the soft strip material, a cutting device provided in front of the cradle, and a cutting processing table included in the cutting device. An advancing / retreating mechanism that allows the pedestal to pass through above and away from the supply destination, and a soft strip-like member that is provided above the tip of the pedestal so as to be able to advance and retreat integrally with the pedestal and move up and down. Of the pressure urging device, and an adsorbing device that is provided in parallel on the downstream side of the pressure urging device and that has an advancing / retreating mechanism independent of the cradle and is vertically movable. .

Return to the upper waiting position. When the first pressing urging member 65 and the pedestal 7 are retracted, the soft strip SW is further ironed, so that the forming drum DR and the pedestal part 3 are squeezed.
Even if slack and wrinkles are generated in the soft band-shaped material SW between 8 and 8, these are removed.

Starts to operate and causes the cutter 54 to reciprocate along the cutter passage 38b. As a result, the soft strip material SW is cut by forming an oblique cut along the inclination of the cutter 54. Next, the suction tool 73 moves up in a state in which the pressing biasing position of the soft strip material SW is sucked (that is, the pressing biasing to the cutting processing table 38a is released). At this time, the first pressing biasing tool 65 does not rise together. Then, in this state, the forming drum DR rotates for the remaining 1/6 rotation, but the advancing / retreating mechanism 62 (see FIG. 4) starts driving so as to be the same speed as the peripheral speed at this time. , Fig. 1 (b)
As shown in, the suction tool 73 and the urging tool 69 are simultaneously advanced toward the forming drum DR. Therefore, the soft strip material SW
Since the relative distance between the front end portion and the end portion which is being taken up by the forming drum DR is invariable, contraction, extension or deformation is also caused in the portion stretched between the forming drum DR and the support base portion 38. It never happens.

By aligning and lowering and pressing the second urging tool 69, a joint is made. After that, the forward / backward mechanism 62
The work head portion 13 is returned by the reverse operation of (see FIG. 4), and the advancing and retracting frame 5 (the support base portion 38) is returned by the reverse operation of the fluid pressure cylinder 35 (see FIG. 4). , So as not to disturb the subsequent tire assembling work on the molding drum DR.

Since the relative distance to the tip of the existing soft band-shaped material remains unchanged, the soft band-shaped material is fed to the supply destination, so that the soft band-shaped material starts to shrink, and hardly expands or deforms. Therefore, for example, when the sidewall is supplied during the tire manufacturing process, the sidewall can be wound around the molding drum (particularly, the joint portion that makes one round) with high accuracy and reliably and quickly. . Along with this, it goes without saying that the production efficiency can be dramatically improved, and full automation as a tire manufacturing process can be realized.
