Description

[Detailed Description of the Invention] [Industrial field of application] The present invention sequentially cuts various long strips of fabric such as tape-shaped knitted fabric, rubber strip, or polyurethane elastic yarn into a predetermined size, The present invention relates to an apparatus for manufacturing an annular material that joins the cut material in an annular shape.

[Conventional technology]

Conventionally, this type of annular fabric manufacturing apparatus, regardless of the width of the individual strip-shaped fabrics to be joined, all target one strip-shaped fabric, dough supply, cutting, reverse polymerization, and joining, It was configured to perform a treatment process (see, for example, Japanese Examined Patent Publication No. 56-50998 or Japanese Utility Model Publication No. 1-26373).

[Problems to be solved by the device]

In the above conventional device, even if the strip-shaped material is fine, it is possible to process only one piece at a time, so in order to improve the productivity per unit time, the processing speed of each motion mechanism part is improved. However, the efficiency of the motion mechanism is greatly restricted by the limitation of the operating speed of each motion mechanism.

In order to avoid such a restriction, it is conceivable that each mechanical portion of the manufacturing apparatus is configured to be able to process a plurality of strips of cloth. However, in the belt-shaped dough feeding device, the cutting device, and the reversing arm for reversing and polymerizing the dough on the dough joining table, simply by setting the working width to a width corresponding to the width of a plurality of band-shaped doughs, Although it is possible to configure it so that it works, when simultaneously joining multiple strips of fabric on the fabric joining table with a single joining device, adjacent thin strips of fabric contact each other. However, there is a problem in that the posture during the reversal polymerization is likely to be disturbed due to the interference with the above, and thus it is difficult to accurately finish the ring shape as intended.

Further, in order to prevent the plurality of strip-shaped fabrics from interfering with each other, it is conceivable to take measures such as erection of a partition piece for guiding the plurality of strip-shaped fabrics on the fabric joining table. Also in this case, the erected partition piece hinders the joining operation of the joining device, the operation of the reversing arm, or an obstacle when removing the annular fabric at the back side from the dough joining table. There is a risk that it will not be practical.

The present invention provides a highly productive device capable of simultaneously producing a plurality of annular fabrics by supplying a plurality of strip-shaped fabrics to one joining device and simultaneously joining the plurality of fabrics. Has that purpose.

[Means for solving the problem]

The technical means of the present invention taken to achieve the above-mentioned object are a dough feeding device that feeds a long strip of dough, a cutting device that cuts the fed dough into a predetermined size, and both ends of the dough cut into a predetermined length. In a device for manufacturing an annular dough, which comprises a pair of reversing arms for superposing the parts on an dough-bonding stand to make an annular shape, and a joining device for joining the annular dough, the following (a) to (d): That is, the configuration described in 1) is provided.

(A) The dough feeding device, the cutting device, and the reversing arm are each configured to be capable of simultaneously processing a plurality of strip-shaped doughs, and the reversing arm is joined in a direction tolerated in the dough feeding direction. It is arranged so as to polymerize the dough edges at a reversal polymerization position on the bonding table remote from the bonding working position of the device.

(B) On the dough joining table, an auxiliary supporting member that supports the lower side of the reversely superposed dough and a dough pressing member that presses the upper side of the dough at a position facing the auxiliary supporting member are superposed. A dough holding device for holding a plurality of doughs is provided, and the dough holding device is configured to be able to change the position from the reverse stacking position to the joining action position while holding the plurality of strip-shaped doughs. Has been done.

(C) At a reverse stacking position away from the joining action position of the dough joining table, a space regulating posture that projects above the dough joining table upper surface and is located between a plurality of strip-shaped doughs, and more than the dough joining table upper surface. A space regulating member is provided so that the posture can be freely changed between the retracted posture in which the lower side is retreated.

(D) Around the dough joining table, the belt-like doughs located on both sides of the interval regulating member are pressed toward the interval regulating member by moving closer to the interval regulating member in the direction along the upper surface of the dough joining table. Then, a width-shifting device that regulates the adjacent interval between the plurality of strip-shaped fabrics to a predetermined size is provided.

[Action]

The effect of taking the above technical means is as follows.

Since the reversal stacking position by the reversing arm is set apart from the joining action position of the joining device, it is possible to arrange the required devices such as the space regulation member at the reversal overlapping position while avoiding mutual interference with the joining device. .

That is, it is difficult to dispose the interval regulating member because there are various members for joining at the joining action position, but as a space for disposing the interval regulating member and the like, in the reversal superposition position where there is no joining member. Since the space under the dough joining base is used, it can be disposed without interfering with the joining device.

b. When a plurality of strip-shaped fabrics are reversely polymerized on the fabric joining table, the strip-shaped fabrics are reversed-polymerized with the spacing regulating member positioned between the plurality of strip-shaped fabrics, and the strip-shaped fabrics are spaced by the width-shifting device. Since it can be aligned with the control member as a reference,
While avoiding mutual interference between the band-shaped fabrics, the interval between the band-shaped fabrics is also defined by the interval regulation member, and it is easy to avoid posture disturbance.

c. A dough holding device is provided on the dough joining table, and multiple strips of dough can be moved to the joining action position while being sandwiched, thus disturbing the posture of the strips of dough aligned in the reverse stacking position. The desired joining can be performed without the need.

d. Since the space regulating member is retracted downward from the upper surface of the cloth joining base, there is no obstacle to the movement of the cloth by the cloth holding device or the takeout after the cloth is joined in the annular shape.

[Effect of device]

By the operations described in a. To d. Above, it is possible to obtain the effect of simultaneously joining a plurality of strip-shaped fabrics by using one joining device and manufacturing a plurality of annular fabrics with high productivity. .
