Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to an apparatus for continuously producing thread spirals as intermediate products such as cleaning mops.

Conventional technology Cleaning brushes and brushes for removing debris from clothes.

It is often manufactured by making a thick thread such as wool into a ring shape and planting it on a support. Therefore, the tip of the implanted thread has a ring shape. To manufacture such mops and brushes, first a spiral of thread is produced and then attached to a support.

Conventionally, the spiral body as described above has two balls (P) erected on a base (A) as shown in FIG.

(P) Wrap the thread fFl between the threads to form a spiral (S)
It is manufactured by first making a fabric and then sewing the central part in the length direction. The sewing at this time is performed with the spiral body (S) attached between the balls fP) and (P). When the sewing is completed, the sewing product is removed from the balls (P) and (P) and used as intermediate products such as motsupu and brushes.

Problems to be Solved by the Invention In the above-mentioned intermediate product, a large number of rings have already been sewn into a ring shape, so that a mop or a brush can be easily produced by attaching it to a holder.

However, the method of making a thread spiral (Sl) by winding a thread (Fl) between two balls (Pi, tP1) is a so-called batch method in which the thread is stretched between two balls (Pi, tP1). , TS) must be removed from the balls (P), (P) each time the unit spiral body TS) is completed, and there is room for improvement in terms of productivity and workability.

The present invention was made in order to fundamentally eliminate such poor productivity and workability.
The object of the present invention is to provide an apparatus for continuously producing S).

Means for Solving the Problems The apparatus for continuous production of thread spirals according to the present invention has two parts connected to each other in parallel and running in opposite directions.
A running mechanism (1) equipped with a pair of endless running belts (11), (Ill), a drive device (2) for driving the running mechanism (1), and a thread (F) that is rotated and fed out while rotating the running mechanism ( 1), both endless running belts (11), (1
It is characterized by being equipped with a winding rack mechanism (3) that winds the winding rack over 11 spaces.

In this case, more specifically, it is particularly desirable to adopt the following configuration.
The traveling mechanism (1) is supported on the mounting table (4) only by the floating sphere (K), and the endless traveling zone (
A magnetic material (old) is installed on the drive wheel (12a) of the support wheel (12) supporting the support wheel (11), while a driving force transmission member (21) attached with the magnetic material (M2) is installed on the drive device (2). ), and the driving force transmission member (21) is provided with the support wheel (
12) is placed at a position facing the support ring (12) with a small interval therebetween without contacting the support ring (12), and furthermore, both magnetic bodies (M1
), (M2) is made into a magnet so that an attractive force is exerted between both the magnetic bodies (M1) and (M2), thereby causing the driving device (2) to move the traveling mechanism (
1) The driving force is transmitted to the magnetic body (M1), f, installed on the driving force transmitting member (21) and the support wheel (12).
This is done only by the suction force of M2), and the thread (Fl) unwound from the winding rack mechanism (3) is sequentially wound onto the endless running belts (11), (11) of the running mechanism (1). .

The present invention will be explained in detail below.

The apparatus for manufacturing a thread spiral body of the present invention has a running mechanism (1
), a drive device (2), and a winding rack mechanism (3).

The traveling mechanism (1) includes a pair of endless traveling belts (11), (11) that are arranged in parallel and connected to each other and run in opposite directions. Endless running zone (
11), flat belts, ■belts, chino belts, etc. are used;
A chino is suitable for moving the spiral body (S) in a state where it is wound on a rack. These endless running zones (u)
, (11l each support wheel (12), (12)
The rotation directions of the two are set to be opposite to each other.

One of the supporting wheels (12) is a drive shaft (12al), and the other is a driven wheel (12b).The driving device (2) is for driving the traveling mechanism (1).

The winding rack mechanism (3) unwinds the thread (Fl) while rotating it, and rolls out both endless running belts (11) of the running mechanism (1).
), (111).

The traveling mechanism (1) is arranged on a mounting table (4). The support of the traveling mechanism (1) to the mounting table (4) is preferably carried out using only a floating sphere (Kl), and an endless traveling belt (11), which will be described later, and a thread (
During the forward movement of F), the thread (F) moves along the endless running zone (11
), (111 and the sphere fK). In order to allow the thread (Fl to slip through), the repulsive force of the magnet causes the endless running zone fi1), (11) to be connected to the stand (4).
It is also possible to adopt a mechanism that floats it upward.

A magnetic body (M1) is installed on the drive shaft (12a) of the support wheel (12) that supports the endless running belt (11). On the other hand, the drive device (2) is provided with a driving force transmitting member (21) attached with a magnetic body (M1), and the driving force transmitting member (21) is located at a position facing the support wheel (12). The supporting ring (12) is arranged at a small interval without contacting the supporting ring (12)6, and both magnetic bodies (M1) are arranged at a small distance (M1) (by making one of them a magnet).

(M1) so that suction force is applied between them.

By devising in this way, the driving force is transmitted from the driving device (2) to the traveling mechanism (1) through the magnetic body (M1) installed in the driving force transmitting member (21) and the support wheel (12). ), (M1) is performed only by the attraction force.

The driving force transmitting member (21) is connected to the electric motor of the driving device (2).
22) It rotates by getting power from it. At that time, the driving force transmission member (21) and the support wheel (12) are arranged with a gap between them without contacting each other, but the attraction force between the magnetic bodies (M1) causes the support wheel to (12) rotates together, and the endless running zone (11) also runs accordingly. In addition, in order to perform the above-mentioned entrained rotation, it is necessary to make the distance between the magnetic bodies (M1) as small as possible, and specifically, create a distance that allows the thread to pass therethrough.

By doing this, the yarn fF) unwound from the winding rack mechanism (3) is transferred to the endless running belt (
11), (111), and a spiral body (Sl
becomes.

In order to fix the shape of this spiral body (S), it is preferable to provide a sewing machine (5) at the terminal end side of the traveling mechanism (1). That is, the thread (F) sent out in a spiral shape by the traveling mechanism (1) is sewn at the center in the longitudinal direction by the sewing machine (5), and is continuously discharged as a spiral body (Sl). .

This spiral body (S) is cut into a predetermined length to produce intermediate products such as mops and brushes.

Note that the pitch of the thread fFl of the spiral body (S) is determined by the rotational speed (angular velocity) of the thread (F) paid out from the winding mechanism (3), and
By adjusting the speed of movement of the endless running belt (11), the desired result can be obtained. For example, V: moving speed of endless traveling zone (11) (cm/5e
c) ω: Angular velocity of thread (F) (radian/5ectt: period (
secl p: pitch fcm), the period is t=2π/ω...■The pitch is p=tv=2πV/ω...■.

Use wool yarn with a thickness of 9.3 cm as thread (F),
Assuming that it is rolled up without any gaps, by substituting p = 0.3cm into the above formula 0, v = (
0,3/2π) ω ...■ is obtained.

The unwinding angular velocity of the thread (Fl) is 2π radian/5ec (1
sec), then from equation (2), the moving speed of the endless traveling zone (11) is v = 0.3 cm/sec.

Usually, the pitch p is 0.3 cm to 2.0 cm, so the moving speed of the endless running belt (11) and the unwinding angular speed ω of the thread (F) are set to 0.
It is calculated from the formula and used.

Examples of the values of V and ω in the above pitch range are as follows.

p(CII+)ω(radian/5ee) v (c
m/5ee)-0,31(hc(5 rotations/5eC11,

04π (214,0 2π (1j 2.0 1π (0,511,0) As you can see from the table above, normally the endless running zone (11)
The moving speed ■ is 1.0 to 10.0 cm/sec, and the thread (F
The feeding angular velocity ω of l is 1π to 10π radian/sec
A value within the range of is adopted.

In order to manufacture a spiral body (Sl) using the apparatus of the present invention, first, the drive device (2) is operated and the drive force transmission member (
21) Rotate. When the driving force transmission member (21) rotates, the magnetic body (M2) installed thereon and the support wheel (
12) drive wheel (magnetic material (M2 installed on the 12al side)
) attract each other and the drive wheel (12a) also rotates, so that the endless running belt (11) also starts running accordingly. In addition, a pair of endless running belts (11),
fxi) is configured to run in a direction away from the winding rack mechanism (3).

Thereafter, the thread (F) is let out from the winding rack mechanism (3) and wound around the outside of the endless running belt (IIL (11)).
Since it is wound up while progressing to (11), it is wound up while sequentially forming a spiral body (Sl).

As the helical body (S) progresses, the thread (F
l comes into contact with the sphere (K) that supports the traveling mechanism (+1), but since the traveling mechanism (1) is only placed on the sphere (K), the thread (F) is in contact with the sphere (Kl) by itself. Create a gap between yourself and the traveling mechanism (1), cut in, and continue moving forward.

Spiral body (Sl is an endless running zone (11), (11
), the sewing machine (
5), the center part of the spiral body (S) is sewn into a band shape by the sewing machine (5), and the intermediate product spiral body (S) is supplied to the subsequent product. In this case, since a gap larger than the thickness of the thread fF is provided between the drive shaft (12al) and the driving force transmission member (21), the spiral body (S) slides through the gap and runs. Mechanism (1
) can be removed from the list.

Example The present invention will be further explained below with reference to Examples.

The two endless running belts (11) and (111) are connected via a connecting rod (14).The connecting rods (14) are connected to each other by fitting in their central parts, and bolts are used to connect the connecting rods (14). The length can be adjusted using the line axis (14a).

A plurality of magnetic bodies (Mll) are fitted to the drive wheel (12a) on the side receiving power transmission.
21).

The traveling mechanism (1) configured in this way has a mounting table (4).
0 sphere (Kl is a magnetic body (Ma) fitted in the lower support wheel support plate (13a)
and the magnetic body (M4) fitted on the mounting table (4), so the traveling mechanism (1) is supported by the top of the sphere fK). Since one endless running belt (111) is supported using two spheres (K), the running mechanism (11 is composed of two balls, so the running mechanism (11 has a total of 4 pieces) As the sphere (K) supported by the sphere (Kl), a chrome-plated iron ball with a polished surface and a diameter of 10 mm was used.

In this way, the traveling mechanism (1) is connected to the floating sphere (Kl
The magnetic material (M31.
(M4) is covered with a ring (Ma), and the ring (
A dam was created using Ma) to prevent the sphere [K) from falling.

The drive device (2) is a mechanism for operating the traveling mechanism (1), and includes an electric motor (22) provided at the bottom of the mounting table (4).
, a pulley (23) that transmits the power of the electric motor (22),
(23), a belt f241. stretched over the pulleys (23), +23). (24), a shaft (25) that pivotally supports one pulley (23), and a driving force transmission member (211, +21) provided on the upper part of (251).

In this case, the driving force transmitting member (21) is arranged to face the driving wheel (12al) into which the magnetic body (M1) is fitted. When the electric motor (22) operates, its rotation is caused by the belt (241).
The driving force is transmitted to the driving force transmitting members (21) and (211) through the tensioned pulleys (23) and (231) of (24), and they rotate.
．． Since +211 has to rotate 4 in opposite directions, one pulley (23), +231
The belt (24) between the driving force transmitting members (21) and the driving wheel (1
2al, and a drive wheel (12a) on the surface opposite to (12a).
A magnetic body (M1) is provided opposite to the magnetic body (M1) on the al side. Since it is configured in this way, the driving force transmission member (21) and the driving wheel (12al) are not directly connected, but the attractive force due to the magnetic force between the magnetic bodies (M1) and the magnetic bodies (M1) is generated. As a result, the drive wheel (12a) also rotates as the drive force transmission member (21) rotates.

When the drive wheel (12al) rotates, the endless running belt (11) stretched thereon also operates.
) The driving wheel (12al) is rotated so that the moving direction of the outer endless running belt (11), fi1 is in the direction away from the winding frame mechanism (3), which will be described later.

The winding rack mechanism (3) is a mechanism that pays out the thread (F) toward the traveling mechanism (11), and is equipped with an electric motor (31), the electric motor (31
) transmits the power of the pulley (3) via the belt (33).
2), (32), and the pulley (32), +3
It consists of a yarn providing arm (34) that is pivotally supported on one side of the motor (2) and that feeds out the yarn (Fl) while rotating.
1), the rotation of the belt (33) is transmitted through the tensioned pulleys (32) and (321), and the yarn providing arm (34) rotates.

The yarn offering arm (34) is made by bending a hollow vibrator into two stages. Thread (Fl) from multiple spools (35)
are bundled and inserted into the rear end of the yarn supplying arm (34), pulled out from the tip and set on the endless traveling belt (11) of the traveling mechanism +11, and then rotating the yarn supplying arm (34). As the arm (34) rotates, the thread (F)
, is wound around an endless running belt (11), (,11).

(5) is a sewing machine provided on the downstream side of the traveling mechanism (11), and is for sewing the center portion of the spiral body (S) that has advanced.

To manufacture the thread spiral (S), first, the thread (Fl) of the bobbin winder (35) is bundled and passed through the thread offering arm (34), and its tip is secured to the endless running belt (11). After that, the electric motor (22) and the electric motor (311) are energized to operate them.
) is transmitted to the driving force transmitting members (21), (211) through the pulleys (23), (231), causing them to rotate. In this case, the rotation of the driving force transmitting members (21), (21
) has a magnetic body (M1), and a drive wheel (12
a), (12al is also provided with a magnetic material (M1), so the drive wheel (
12a1. (12a) also rotates. In addition, their rotation directions are the stretched endless running belt (11), DI
They rotate in opposite directions so that both the outer sides of the + move in the direction away from the winding rack mechanism (3). On the other hand, the electric motor (3
1), the yarn providing arm (34) rotates via the pulley (32) and (321), and the yarn (34) is supplied to the traveling mechanism D).
Wrap F).

In this case, the endless running zone (11) of the running mechanism (1)
, (111) is moving in the direction (downstream direction) away from the winding rack mechanism (3), so the thread (Fl) advances while being wound around it, forming a spiral body (S). The spiral body (S) comes into contact with the sphere (K) during its progress, but since the sphere (K) is in a floating state, the spiral body (Sl) comes into contact with the sphere (K) and the support wheel support plate ( 13).

Furthermore, since a gap is formed between the drive wheel (12a) in which the magnetic body (M1) is fitted and the drive force transmission member (21), the spiral body fsl passes through the gap and travels. Mechanism (11) can be extracted from the system. Traveling mechanism (11)
) The spiral body (S) that has reached the tip of the center part is sewn into a belt shape by the sewing machine (5), and the spiral body (S) is finished sewing as shown in FIG. It is discharged outside.

When the discharged spiral body (S) is cut into a predetermined length and implanted in a support member fT1), a mop (Tl) as illustrated in FIG. 8 is obtained.

Effects of the Invention In other words, the apparatus for continuously producing a thread spiral according to the present invention is capable of continuously and automatically producing a spiral (Sl), which conventionally could only be produced by a batch method. This greatly improves productivity and maintains consistent quality.
