Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is, for example, a corded belt that is a constituent member of a tire, in particular, a so-called high-angle belt in which a cord is embedded at a high angle close to 90 degrees with respect to the rotation center axis direction when configured in a tire. The present invention relates to a continuous piece cutting device.
[0002]
[Prior art]
Tires using high-angle belts have been manufactured. This high-angle belt has a narrow width in which rubber is coated on a plurality of steel cords arranged in parallel as shown in FIG. The continuous strip-shaped piece is transported onto the cutting table 2 via the first transporting means 4, and the movable blade 20 of the cutter is dropped on the strip-shaped portion at that position to be cut at a predetermined width and high angle, The talent pieces are transported and wound around the large-diameter pasting drum 3 rotated by the second transport means 5 and joined together. By repeating this operation, a belt is formed on the tension drum 3, and the formed belt is peeled off from the sticking drum 3 by a winding device and wound on a winding roll.
[0003]
By the way, in the above conventional belt manufacturing apparatus, the side piece to be separated when the continuous piece is cut at a high angle is not held. In other words, for a piece cut off at a low angle or at a right angle, there is little behavior associated with the cut, and positioning for joining etc. is not so much even if it is separated and transported without holding it forcibly. There is no problem, but in high-angle cuts such as 75 ° to 86 °, the acute angle end on the side to be cut off is covered with the torsion of the wire at the time of cut-off unless there is a piece holding at the time of cut-off. Due to the shrinkage of the rubber, etc., it is slightly displaced (about 1mm), and since it is cut off at a high angle, the wire-covered rubber has a sharp edge at the edge, and the sharp end of the piece to be cut off is a cutter. There is a problem that it is sandwiched between the blade and the support table and dragged when the same piece is transported, and the shape is further deformed, so that an error occurs when winding the talent pieces and joining the talent pieces together. There is a problem that the elephant becomes difficult.
[0004]
Therefore, in order to hold the cord piece when cutting at a predetermined angle, the cutter is composed of a cutting lower blade and a cutting upper blade (rotating blade), and a plurality of air suction holes are formed in the cutting lower blade. When the sheet member cord piece (raw fabric) is cut at a certain angle with respect to the cord, the cord piece is placed on the lower cutting blade, and air is sucked. Air is sucked from the hole to fix the code piece to the cutting lower blade, and in that state, the code piece is cut by the cutting upper blade (rotating blade) and the cutting lower blade (Patent) Reference 1).
[0005]
However, if the tire member cord part piece is simply held by the air suction hole of the cutting lower blade, the sharp angle end on the side to be cut off is sufficiently thin in high angle cutting such as 75 ° to 86 °. Since the suction cannot be performed, the conventional problem cannot be solved.

DETAILED DESCRIPTION OF THE INVENTION
One embodiment of the continuous part piece cutting apparatus of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view schematically illustrating an embodiment of a continuous piece piece cutting apparatus according to the present invention, and FIGS. 2A to 2D are side views schematically showing a process of cutting in the cutting apparatus. is there. .
In FIG. 1, reference numeral 40 denotes a talent table, that is, a vacuum table, on the surface of which a large number of small holes communicating with a vacuum source (not shown) are provided in order to suck and hold the talent pieces placed on the table in a vacuum. As shown in the figure, the whole is substantially rectangular. Further, as shown in each drawing of FIG. 2, the lower end thereof is supported by an arbitrary elastic support body 50 using, for example, a spring or the like, and is lowered by pressing with the movable blade 20 from above (in this embodiment, about It can be moved up and down so that it can move about 10mm). The vacuum table 40 has one side in contact with the side surface of the fixed blade 30 of the cutter, and the other side is always pressed by the vacuum table holding means 60 and held between the fixed blade 30 and the holding means 60. Is maintained.
[0010]
The vacuum table holding means 60 includes a cylinder 61, a cylinder rod 62, and an attachment 63 that is provided at the tip of the cylinder rod 62 and acts to constantly press the side portion of the vacuum table 40. This attachment 63 has a vacuum table 40 contact surface 63a made of synthetic resin such as nylon (registered trademark), for example, and this contact surface 63a is recessed on the surface on the attachment 63 side as shown in FIGS. Or the step part 64 is formed. When the step 64 is pushed down at the tip of the movable blade 20 of the cutter where the vacuum table 60 descends and descends against the elastic force of the elastic support, the corner of the vacuum table 40 is at its bottom dead center. It works as a lock to prevent the table from moving up.
[0011]
Next, the operation of the continuous piece cutting apparatus of the present invention configured as described above will be described.
In FIG. 1, first, a continuous piece M for making a decision has a path inclined by, for example, 75 ° to 86 ° with respect to the fixed blade 30 of the cutter from the upper right part of the figure toward the lower right side by an extruder (not shown). When it is pushed and conveyed, and passes over the fixed blade 30 and is conveyed to the vacuum table 40, the vacuum table 40 holds the continuous piece M by vacuum suction, and in that state, the movable blade 20 of the cutter is lowered to a predetermined level. Decide by width.
That is, after the movable blade 20 of the cutter descends from the state of FIG. 2A and comes into contact with the continuous piece M, it is elastic in a state in which the continuous piece M is further restrained with the vacuum table 40 as shown in FIG. 2B. The pressed down continuous piece M is completely cut against the elastic force of the support 50.
[0012]
When the movable blade 20 of the cutter reaches the bottom dead center of the lowering, the upper end portion of the vacuum table 40 is positioned at the stepped portion 64 of the contact surface 63a of the attachment 63 of the vacuum table holding means 60 as shown in FIG. 2C. Reach. Here, since the attachment 63 is always urged toward the vacuum table 40 by the cylinder 61, the stepped portion 64 advances to the vacuum table 40 side and engages with the side portion.
[0013]
When the movable blade 20 of the cutter starts a rising stroke in this state, as shown in FIG. 2D, the movable blade 20 of the cutter is raised, but the vacuum table 40 applies the elastic force of the elastic support body 50 from below at that position. In response, the upper end portion is pressed against the stepped portion 64, that is, held in a locked state.
In addition, the talent piece is held on the vacuum table 40 while being vacuum-sucked.
After the cutter blade 23 is raised, the cylinder 61 is operated to retract the rod 62 to disengage the vacuum table 40 from the attachment 63, so that the vacuum table 40 returns to its original position by the elastic force of the elastic support 50. To rise.
[0014]
Next, the talented piece M sucked and held on the vacuum table 40 is next sucked by a suction hand having a magnet (permanent magnet) at the tip and conveyed to a predetermined position. That is, the magnet is housed in a casing made of a material that can transmit magnetic lines of force, such as iron, and descends in the casing at the adsorption position of the age piece M, acts on the steel wire of the age piece M, and sucks it. In the release position, the inside of the casing is raised to release the old piece M.
