Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a foil paper having a large number of juxtaposed filament yarns which are continuous through an ear portion at one end when weaving a foil-containing fabric. The present invention relates to a cutting foil yarn cutting device for separating the cutting foil yarns according to a parallel order and using them for horizontal loading.

[Conventional technology]

Examples of this type of device include a cutting paper tensioning table movably supported on the base, a cutting paper clip extending in the front-rear direction attached to one end of the cutting paper tensioning table, and the other side of the cutting paper tensioning table. A pair of cutting foil thread feeding rollers installed (attached) on the edge and extending in the forward direction (moving direction) of the cutting paper tensioning table, and a pair of cutting foil thread feeding rollers on the cutting foil paper clip installed (attached) on the base. In the above, a rotary disk cutter facing the adjacent portion is provided, and the cutting paper is placed on the cutting paper stretcher by gripping the ears with a cutting paper clip and sandwiching the free end of the cutting foil group by the cutting foil feeding roller pair. , In the tensioned state, by intermittently advancing the cutting foil paper tensioning table by a small amount corresponding to the width of the cutting foil thread, the ear adjacent portions of each cutting foil thread are sequentially engaged with the rotating disk cutter, While cutting the part,
It is known that each cutting foil thread cut in this manner is sent out to a lateral position suitable for horizontal insertion through a pair of cutting foil thread feeding rollers (see, for example, JP-A-55-107551). .

[Problems to be solved by the invention]

However, in the known device described above, even if the foil foil is stretched on the foil foil tensioning table with sufficient tension in the vertical and horizontal directions, the adjacent foil foil threads overlap or intersect at the ear adjacent portion to be cut. Therefore, there is a problem that 2-3 cutting foil yarns may be cut at the same time or may be cut in the reverse order. In addition, since some of the adjacent foil foils may adhere to each other via the coloring agent used in the foil paper, the cut foil yarns are cut to the side via the foil feed roller pair. There is also a problem that sometimes it cannot be sent out.

[Means for solving problems]

According to the present invention, the above-mentioned problems are caused by the traveling speed of the cutting paper edge fixing belt and the side portions of the cutting paper edge fixing belt supported on the base so as to be able to move forward and the base. It was installed (attached) to a cutting paper tensioning table including a cutting foil thread part supporting table that was supported so that it could move forward at the same speed, and a base.
The cut paper edge fixing belt is located on the side close to the cut foil thread support table and faces the cut foil thread support table). Of the cutting foil thread supporting table installed at the side of the cutting foil thread supporting table remote from the cutting paper edge fixing belt of the cutting foil thread supporting table and rotating at a linear velocity slightly higher than the traveling speed of the cutting foil thread supporting table. By a pair of cutting foil thread feeding rollers extending in the forward (moving) direction, and a cutting foil thread cutting device equipped with (attaching) a cutting foil thread aligning disk facing the top or the adjacent portion of the cutting foil thread aligning disk. Solve.

[Action]

In the device of the present invention, generally, the ears of the cut foil paper are adhered to the cut paper ears fixing belt so that the inside of the ears slightly protrudes from the side edge on the side close to the cut foil thread part support table. While firmly fixing via a tape or the like, by sandwiching the free end portion of the cutting foil thread group between the cutting foil thread feeding roller pairs, so that the substantial portion of the cutting foil thread group extends on the cutting foil thread portion support table,
With the foil foil stretched on the foil foil stretcher, the foil edge fixing belt, the foil thread support table, the foil thread alignment disk, the foil thread cutting means, and the foil thread feed roller pair can be used at the same time or at substantially the same time. The cutting foil is cut and cut, cutting the foil adjacent to the ear portion of the foremost cutting foil while advancing the cutting paper to a position where the foremost portion extends through the top of the cutting foil alignment disc or its vicinity. By repeating the operation of moving the foil sideways, the cutting foil yarns are sequentially transferred to a position where they can be horizontally inserted.

When this cutting foil paper is moved forward, the cutting paper sheet portion adjacent to the side edge of the cutting paper sheet edge fixing belt on the side closer to the cutting foil thread portion support table moves to the position of the cutting foil thread alignment disc. When placed on the foil paper aligning disc, the substantial portion of the foil foil is pinched by the pair of foil foil feeding rollers or the pinching force and the feeding force from the point of fixation of the edge of the foil paper by the belt fixing belt. Against the above, the sheet is sequentially pulled and moved toward the cutting paper edge fixing belt side by an amount corresponding to the amount of lifting of the chevron by the cutting foil thread alignment disk. Therefore, if there is adhesion between adjacent cutting foil threads, this adhesion is released and each cutting foil thread is in a separated state, while the cutting paper is moved to this cutting paper edge fixing belt side. The cutting foil thread alignment disk squeezes from the ear side toward the cutting foil thread side and aligns them in a predetermined parallel order, so that there is no crossing or overlapping of the adjacent adjoining cutting foil threads, and the cutting foil thread alignment is performed. The foil foils placed on the rollers are separated from each other because the linear velocity of the foil foil aligning disk is slightly higher than the traveling and moving speed of the foil paper tensioning table. Therefore, the cutting foil yarn cutting means cuts the cutting foil yarn one by one in a predetermined parallel order.

In the device of the present invention, the free end of the cutting foil yarn group is clamped by the pair of cutting foil yarn feeding rollers, and therefore the frictional force corresponding to the rotational driving force acts on the free end of the cutting foil yarn group during rotation. Generally, this rotational driving force, and thus the frictional force against the cutting foil yarn, need not be so great as to cause damage such as abrasion to the free end portion of the cutting foil yarn, and the free end portion of this cutting foil yarn is cut off after weaving. Since it becomes the fabric ear portion, even if abrasion or the like occurs, there is no problem.

〔Example〕

The present invention can be implemented, for example, in the shape shown.

In this illustrated example, all are arranged on the base 10, and the cut paper edge fixing belt 14 and the cut foil thread support table 26, the cut foil thread aligning disc 36, and the cut foil paper as an addition means, which form the cut foil stretcher 12, are shown. Ear pressing plate 38, cutting foil cutting disc cutter 40 as cutting foil cutting means, and a pair of cutting foil feeding rollers 44.
Is equipped with.

The belt 14 for fixing the edge portion of the cut paper is a drive belt wheel 16 and a driven belt wheel 18 which are installed on the right end portion of the base 10 in the front-rear direction (upper front, lower bottom in FIG. 1) at intervals. Between the tables
It extends in a state of being supported by 20, and travels forward toward the driven belt wheel 18 by rotational driving of the drive belt wheel 16 via the drive shaft 24 extending from the electric motor 22.

The cutting foil thread part support table 26 is provided on the base 10 with a space left and right, and on the two supporting rails 28 extending in the front-rear direction, the cutting foil paper fixing surface having the same height as the cutting paper edge fixing belt 14 is provided. And a slider 30 attached to the back portion between the support portions of the support rail 28 is engaged with a slide guide 32 extending in the front-rear direction on the corresponding base 10 portion. 30 Mounting part and right support rail 28
A part between the supporting portions extends in the front-rear direction on the base 10 and via the drive shaft 24 extending from the electric motor 22 that controls the drive of the cutting paper sheet ear fixing belt 14, and the cutting paper sheet fixing belt 14 and It is fixed to a part of a drive belt 34 that is driven to move forward synchronously and at the same speed. As a result, the cutting foil thread portion supporting table 26 is advanced at the same speed in synchronization with the cutting paper edge fixing belt 14.

The cutting foil thread aligning disc 36 is attached to the left end portion of the driven belt wheel 18 on which the cutting paper edge fixing belt 14 is hung, and has a diameter larger than the diameter of the driven belt wheel 18.

The base end of the foil cutting paper pressing plate 38 is attached to the base 10, and the side edge on the left side of the front end of the foil cutting edge fixing belt 14 adjacent to the cutting foil thread aligning disc 36 on the right side is slightly formed. It extends back and forth so as to cover it at a certain interval.

The cutting foil cutting disc cutter 40 is located above the front end of the cutting paper edge fixing belt 14 in a state where the lower end peripheral surface on the left side thereof is lightly pressed against the peripheral end surface on the right side near the top of the cutting foil thread aligning disc 36. Thus, the electric motor 22 is rotationally driven via the gear / belt electric mechanism 42.

On the other hand, the pair of cutting foil thread feed rollers 44 is made of rubber, and is installed up and down through the bracket 49 at the left end of the cutting foil thread part support table 26 in a state where the contact portion belongs to the cutting foil paper tension surface. An electric motor 50 installed on the base 10 is rotationally driven through a long drive gear 46 extending in the front-rear direction and a passive gear 48 concentrically attached to the end portion of each foil feed roller 44.

In this illustrated example, the edge portion of the cut foil paper 52 is a belt for fixing the cut paper edge portion.
A part of which is slightly protruded from the left side edge of the belt 14 and the front edge of the foil foil 52 extends over the portion immediately before the foil foil alignment disk 36 and is fixed to the belt 14 with an adhesive tape. On the other hand, by sandwiching the free end portion of the cutting foil thread group between the pair of cutting foil feeding rollers 44, the cutting paper 52 is stretched on the cutting paper tensioning table 12, and the electric motor 22 is activated first. The cutting foil edge fixing belt 14, the cutting foil thread supporting table 26, the cutting foil thread aligning disk 36 and the cutting foil cutting disk cutter 40 are operated at the same time, and at the same time, the pair of cutting foil feeding rollers are activated through the activation of the electric motor 50. Activating 44, cutting paper
Move forward while tensioning the whole 52. At this time, the driven gear 48 attached to the foil feed roller 44 located on the lower side slides on the drive gear 46 to change the meshing position to the front side.

As a result, the ears 54 of the wrapping paper 52 on the left side edge of the wrapping paper ears fixing belt 14 enter under the wrapping paper ears holding plate 38, while the wrapping paper adjacent to this on the left is the wrapping foil. It is placed on the top of the thread alignment disc 36 and lifted in a chevron shape,
It advances toward the vicinity of the apex facing the cutting foil cutting disc cutter 40. At this time, the mountain shape is lifted by the cutting foil thread aligning disc 36 of the cutting foil paper portion by fixing the ear 54 on the right side of the cutting foil paper portion to the cover of the cutting foil paper ear holding plate 38 and the cutting foil paper ear fixing belt 14. , The movement of the cutting foil feed roller 44
It is performed while displacing to the right against the pinching force and feed force of the pair. For this reason, if adjacent cutting foil threads 56 are attached,
This attachment is released, and the cutting foil threads 56 are completely separated. Also, due to the displacement of this cutting paper part to the right,
Since the cutting paper sheet portion is squeezed by the cutting foil thread aligning disk 36 from the ear portion 54 side toward the cutting foil thread 56 side, the adjacent cutting foil threads 56 in this portion are aligned in a parallel order. Further, 56 pieces of the cutting foil thread arranged on the cutting foil thread aligning disc 36 have a diameter of the cutting foil thread aligning disk 36 which is larger than that of the driven belt wheel 18, so that the former linear velocity is the latter, in other words, the cutting foil paper ear portion. Since it is higher than the traveling speed of the fixed belt 14,
They are in a state of being separated from each other.

In such a state, when the foremost cutting foil yarn 56 advances and its ear adjacent portion extends to the vicinity of the top of the foil foil aligning disc 36, the ear adjacent portion cut foil yarn cutting disc cutter 40.
To be cut.

When the cutting of the frontmost end of the foil foil 56 is completed in this manner, the electric motor 22 is stopped, while the tip of the foil foil 56 is horizontally inserted through the pair of foil feed rollers 44. The yarn is sent to a position where it can be held by the thread grip, and the electric motor 50 stops operating at this point.
For example, a photoelectric sensor for cutting detection that detects a descent of the cutting foil yarn 56 adjacent to the ear portion due to cutting, a photoelectric sensor for yarn feeding detection that detects the presence or absence of the cut foil yarn 56 at a predetermined position, and the like of the electric motors 22 and 50. It is done by operating control).

After pulling this cutting foil yarn 56 out of the apparatus through, for example, the side insertion yarn grip, the electric motors 22 and 50 are operated again, and the above operation is repeated, whereby the frontmost cutting foil yarn 56 is sequentially separated. , I will put it in the horizontal.

In addition to this, the present invention comprises a cutting foil thread cutting means composed of a heating wire cutter, a laser beam cutter, a plasma jet cutter, an ultrasonic cutter, etc. It can be carried out in various modes such as attaching clips or clamps for fixing paper.

〔The invention's effect〕

As is clear from the above description, according to the device of the present invention, each cutting foil yarn of the cutting foil paper can be reliably cut according to the order.
