Description

Toe socks weaving device and the weaving method

The present invention relates to a toe socks weaving apparatus and a weaving method, and more particularly, a toe socks weaving device in which a forward waiting operation of one wheel is deleted after one toe is woven and before another adjacent toe is woven. It is about a weaving method.

As is well known, socks are woven from thread or fiber to be worn on bare feet, such socks comprising an ankle on which the ankle is worn, a heel covering the heel, and a toe and instep covering the soles and feet. Knitting machines are knitted, including the toes and the toes where the toes are worn.

The sock knitting machine described above is implemented as a circular knitting machine (丸 編 機, Circular Knitting), such a circular knitting machine is arranged in a circular knitting needles, so that the knitting of the various patterns from the ankle to the trunk is possible.

Alternatively, there are so-called sewing toe socks formed so that the toes are fitted from the big toe to the little toe, respectively, such sewing toe socks are mostly manufactured by the knitting machine of the flat knitting machine, and also the sock knitting machine of the circular knitting machine.

The glove knitting machine of the flat knitting machine or the sock knitting machine of the circular knitting machine knits five toe parts by repeating the forward rotation and the reverse rotation when knitting the toe socks.

Using the needle lifter to weave the first toe of the five toes, the operation of raising the unnecessary needles on the first toe weave is performed.

In this state, when the weaving of the first toe is completed, the needles raised by the needle lowering device installed on one side of the needle raising device are lowered. Therefore, it is ready to weave the next toe.

After the first toe has been woven, the next toe can be weaved so that the needle lowering device is driven forward to lower all the raised needles when weaving the first toe. At this time, the needle lifter is driven backward.

As such, after the first toe is woven, an unnecessary weaving operation is performed by one forward rotation to make the second toe woven, and the standby state for the descending of the raised needle and the weaving of the second toe is performed through the forward rotation.

When the first toe is woven and then rotates forward, unnecessary needles are raised to weave the second toe by the needle lifter, and the needle lowerer is driven backward, and the second toe is woven.

After the second toe has been woven, the next toe can be weaved so that the needle lowering device is driven forward to lower all the raised needles when weaving the second toe. At this time, the needle lifter is driven backward.

In this way, after the second toe is woven, an unnecessary weaving operation that rotates forward one turn is further performed to weave the third toe. Through this forward rotation, the waiting state for the descending of the raised needle and the third toe weaving is performed.

When the second toe is woven and then rotates forward, the unnecessary needles are raised to weave the third toe by the needle lifter, and the needle lowerer is driven backward, and the third toe is woven.

After the third toe has been woven, the next toe can be weaved so that the needle lowering device is driven forward to lower all the raised needles when weaving the second toe. At this time, the needle lifter is driven backward.

In this way, after the third toe is woven, an unnecessary weaving operation is performed by one forward rotation for the fourth toe to be woven, and the standby state for the descending of the raised needle and the weaving of the fourth toe is performed through the forward rotation.

After the fourth toe is woven, the next toe is woven, and the needle lowering device is driven forward to lower all the needles that were raised when weaving the second toe. At this time, the needle lifter is driven backward.

As such, after the fourth toe is woven, an unnecessary weaving operation of one forward rotation is further performed to weave the fifth toe, and the standby state for the descending of the raised needle and the fifth toe weaving is performed through the forward rotation.

This conventional toe sock loom requires one round of forward rotation to lower the raised needles to weave the next toe after weaving one toe, and thus until weaving the last five toes from the first toe. A total of four wheels of unnecessary forward rotation was further performed. Accordingly, unnecessary weaving of four wheels creates more unnecessary weaves on the first toe tip and toe socks.

Therefore, when weaving the toe portion with a conventional hosiery loom, an unnecessary weaving part is generated, thereby degrading the quality of the woven toe sock and increasing the consumption of the thread.

Figure 4 is a schematic partial front view showing the main part of the present invention, Figure 5 is a flow chart showing a toe socks weaving method of the present invention.

In the toe socks weaving device of the present invention, the lowering cam 40 is installed around the single needle cylinder 10 and the auxiliary raising cam 50 around the counterclockwise side single needle cylinder 10 based on the lowering cam 40. ) Is installed, and the knitting needles 20 raised by the lowering cam 40 after all of the toes are woven down and the unnecessary knitting needles for the next toe weaving by the auxiliary raising cam 50 without the forward rotation waiting operation of one round. Since the twenty points are immediately raised, the forward standby operation of one round is eliminated after one toe is woven and before another adjacent toe is woven.

Toe socks weaving device of the present invention, single needle cylinder (10), knitting needles (20), lowering cam 40, lowering cam cylinder (41), auxiliary lifting cam (50), auxiliary lifting cam cylinder (51) It is made to include.

The needle needle cylinder 10 is rotated in the forward and reverse directions and coupled to the plurality of needle needles 20 in the circumference.

The knitting needles 20 are inserted around the knitting needle cylinder 10 and weave the toe socks. When the toe portion of any one of the five toes is woven, the other portions of the knitting needles 20 are first raised by the actuator 30 and then fully raised to a position which is not woven by the auxiliary raising cam 50 to be described later. do.

The lowering cam 40 is installed at one side of the circumference of the needle needle cylinder 10 to weave one toe, and then weave all the needles 20 when the needle needle cylinder 10 is rotated forward to weave the next toe. Let's do it.

The lowering cam cylinder 41 is connected to the lowering cam 40 to control the lowering cam 40.

The auxiliary lifting cam 50 is installed around the single needle cylinder 10 and is provided at one side of the down cam 40 in the counterclockwise direction to weave the next toe among the needles 20 lowered by the lowering cam 40. Since the unnecessary needles (20) to rise immediately so that you can weave the next toe straight without waiting.

The auxiliary raising cam cylinder 51 is connected to the auxiliary raising cam 50 to control the auxiliary raising cam 50.

On the other hand, the lowering cam 40 and the auxiliary lifting cam 50, a coating layer may be formed. The reason why the ceramic coating is applied to the lowering cam 40 and the auxiliary raising cam 50 is to prevent corrosion. Ceramic coatings are more resistant to corrosion, scratch, abrasion, impact and durability than chromium or nickel chromium plating.

The coating layer is sprayed around the down cam 40 and the auxiliary up cam 50 by a powder composed of 96 to 98% of chromium oxide (Cr ₂ O ₃ ) and ₂ to 4% of titanium dioxide (TiO ₂ ). Is done.

Chromium oxide (Cr ₂ O ₃ ) serves to prevent rust by acting as a passivity layer that blocks oxygen invading into the metal.

Titanium dioxide (TiO ₂ ) is very stable physicochemically and has a high hiding power, thus becoming a white pigment. In addition, the refractive index is high, it is widely used in high refractive index ceramics. It has photocatalytic and superhydrophilic properties. Titanium dioxide (TiO ₂ ), air purification, antibacterial, harmful substance decomposition, pollution prevention function, discoloration prevention function. The titanium dioxide (TiO ₂ ), so that the coating layer is reliably coated around the down cam 40 and the auxiliary up cam 50, decomposes foreign matter attached to the down cam 40 and the auxiliary up cam (50). , To prevent damage to the lowering cam 40 and the auxiliary lifting cam (50).

Here, when chromium oxide (Cr ₂ O ₃ ) and titanium dioxide (TiO ₂ ) are mixed and used, these mixing ratios are 96 to 98% of chromium oxide (Cr ₂ O ₃ ) and titanium dioxide (TiO ₂ ) 2 to It is preferred that 4% is mixed.

When the mixing ratio of chromium oxide (Cr ₂ O ₃ ) is less than 96-98%, the coating of chromium oxide (Cr ₂ O ₃ ) is often broken in an environment such as high temperature, and thus the lowering cam (40) ) And the rust protection effect of the auxiliary raising cam 50 was sharply reduced.

When the mixing ratio of titanium dioxide (TiO ₂ ) is less than 2 to 4%, the effect of titanium dioxide (TiO ₂ ) is insignificant so that the purpose of mixing it with chromium oxide (Cr ₂ O ₃ ) is discolored. That is, the titanium dioxide (TiO ₂ ) is decomposed or removed to remove the foreign matter attached to the circumference of the lower cam 40 and the auxiliary raised cam 50, the lower cam 40 and the secondary raised cam 50 is corroded or damaged To prevent, if the mixing ratio is less than 2 to 4%, there is a problem that takes a long time to decompose the adhered foreign matter.

The coating layer made of these materials has a thickness of 50 to 600 µm around the lowering cam 40 and the auxiliary raising cam 50, the hardness of 900 to 1000 HV, the surface roughness of 0.1 to 0.3 ㎛ Coated.

This coating layer, after spraying the powder powder and the gas at 1400 ℃ at the speed of Mach 2 around the lowering cam 40 and the auxiliary lifting cam 50 by spraying at 400㎛ diamond wheel (Diamond Wheel) And it wraps to 50-600 micrometers using the film.

When the thickness of the coating layer is less than 50 탆, the effect of the above-described ceramic coating layer can not be guaranteed. When the thickness of the coating layer exceeds 600 탆, the above-mentioned effect is insignificant. On the other hand, Is wasted.

While the coating layer is coated on the lowering cam 40 and the auxiliary raising cam 50, the temperature of the lowering cam 40 and the auxiliary raising cam 50 is increased, and the heated lowering cam 40 and the auxiliary raising cam 50 are heated. The lowering cam 40 and the auxiliary raising cam 50 are cooled by a cooling device (not shown) so as to prevent deformation of the lowering cam 40 and the auxiliary raising cam 50.

Therefore, since the coating layer having excellent oxidation resistance is formed around the down cam 40 and the auxiliary up cam 50 which are frequently exposed to the outside, the down cam 40 and the auxiliary up cam 50 are prevented from being oxidized, and the down cam Safety accidents are prevented by the oxidation prevention of the 40 and the auxiliary raising cam 50, and as a result, the lifespan of the toe socks weaving device is extended, thereby reducing maintenance costs.

Toe socks woven by the toe socks weaving device of the present invention is woven in the following manner.

First, in order to weave the first toe portion of the five toes, the auxiliary raising cam cylinder 51 is operated to drive the auxiliary raising cam 50 forward, thus rest except the knitting needles 20 necessary for the first toe weaving. Raise the needles 20.

In this state, the needle needle cylinder 10 has a first weaving step S10 of weaving the first toe as the forward and reverse rotation.

When the first toe portion is woven through the first weaving step (S10), the lower cam 40 is driven forward by the lower cam cylinder 41, thereby lowering the first raised needles 20 that are unnecessary for the first toe weave. Has a strong step (S20).

When all the needles 20 which were raised during the first toe weaving through the first single needle lowering step S20 are lowered, the lowering cam 40 is driven backward by the lowering cam cylinder 41 to the auxiliary raising cam cylinder 51. As a result, the auxiliary raising cam 50 is driven forward to have the first knitting needle rising step S30 to immediately raise unnecessary knitting needles 20 for the weaving of the second toe without a forward rotation waiting operation of one round.

When unnecessary knitting needles 20 are raised to weave the second toe through the first knitting needle raising step S30, the auxiliary lifting cam 50 is driven backward by the auxiliary lifting cam cylinder 51, and the knitting needle cylinder 10 is reversely rotated. It has a second weaving step (S40) for weaving a second toe.

When the second toe portion is woven through the second weaving step (S40), the lower cam 40 is driven forward to have a second knitting needle lowering step (S50) of lowering the unnecessary raised needles 20 for the second toe weaving.

When all of the knitting needles 20 which are raised during the second toe weaving through the second knitting needle lowering step S50 are lowered, the lowering cam 40 is driven backward by the lowering cam cylinder 41, and the auxiliary raising cam cylinder 51 is supported. The auxiliary raising cam 50 is driven forward to have a second knitting needle raising step (S60) to immediately raise the unnecessary knitting needles 20 for the third toe weave without the forward rotation standby operation of one round.

When unnecessary knitting needles 20 are raised in the third toe weaving step S60 through the second knitting needle raising step S60, the auxiliary lifting cam 50 is driven backward by the auxiliary lifting cam cylinder 51, and the knitting needle cylinder 10 is reversely rotated. It has a third weaving step (S70) of weaving the third toe.

When the third toe portion is woven through the third weaving step (S70), the lower cam 40 is driven forward to have a third knitting needle lowering step (S80) for lowering unnecessary raised needles 20 for the third toe weaving.

When the knitting needles 20, which were raised during the third toe weaving through the third knitting needle lowering step S80, are all lowered, the lowering cam 40 is driven backward by the lowering cam cylinder 41, and the auxiliary raising cam cylinder 51 is supported. As a result, the auxiliary raising cam 50 is driven forward to have a third knitting needle rising step S90 for immediately raising the unnecessary knitting needles 20 for the fourth toe weaving without a forward rotation waiting operation of one round.

When unnecessary knitting needles 20 are raised in the fourth toe weaving step S90 through the third knitting needle raising step S90, the auxiliary lifting cam 50 is driven backward by the auxiliary lifting cam cylinder 51, and the knitting needle cylinder 10 is reversely rotated. It has a fourth weaving step (S100) to weave the fourth toe.

When the fourth toe portion is woven through the fourth weaving step (S100), the lower cam 40 is driven forward to have a fourth knitting needle lowering step (S110) for lowering unnecessary raised needles 20 for the fourth toe weaving.

When the knitting needles 20, which were raised during the fourth toe weaving through the fourth knitting needle lowering step S110, are all lowered, the lowering cam 40 is driven backward by the lowering cam cylinder 41, and the auxiliary raising cam cylinder 51 is supported. As a result, the auxiliary raising cam 50 is driven forward to have the fourth knitting needle rising step S120 to immediately raise unnecessary knitting needles 20 for the fifth toe weaving without a forward rotation waiting operation of one round.

When unnecessary knitting needles 20 are raised to the fifth toe weave through the fourth knitting needle raising step S120, the auxiliary lifting cam 50 is driven backward by the auxiliary lifting cam cylinder 51, and the needle needle cylinder 10 is rotated forward and backward. While having a fifth weaving step (S130) to weave the fifth toe.

Toe socks weaving device of the present invention has the following effects.

In the present invention, the lowering cam 40 is installed around the single needle cylinder 10, and the auxiliary raising cam 50 is installed around the counterclockwise side single needle cylinder 10 based on the lowering cam 40. After the toes of the weaving, all the needles 20 raised by the lowering cam 40 are lowered, and the unnecessary needle needles 20 are immediately raised to the next toe weave by the auxiliary raising cam 50 without the forward rotation waiting operation of one round. do.

Therefore, after one toe is woven and before another adjacent toe is woven, one forward waiting motion is deleted, and thus, a total of 4 rounds of unnecessary waiting waiting until weaving the fifth toe from the first toe are eliminated. The action is deleted.

Therefore, unnecessary weaving of four wheels is prevented, so that unnecessary weaves are prevented from being generated at the end of the first toe and the toe sock. Accordingly, unnecessary weaves are prevented from being generated, thus improving the quality of the woven toe sock and the yarn. Consumption is reduced and production is increased.

On the other hand, the knitting needle 20 is preferably made of nodular cast iron.

Nodular cast iron is a cast iron in which graphite is spherically crystallized during the solidification process by adding magnesium and the like to the molten iron of Ivan gray cast iron, so the shape of graphite is higher than gray cast iron. Since the nodular cast iron has a small notch effect, the stress concentration phenomenon is reduced and the strength and toughness are greatly improved.

In the knitting needle 20 of the present invention, the nodular cast iron is heated to 1600-1650 ° C. to form a molten metal, followed by desulfurization treatment, and a spheroidizing treatment containing 0.3 to 0.7% of magnesium was added and spheroidized at 1500-1550 ° C. After the heat treatment is made.

Here, when the nodular cast iron is heated to less than 1600 ° C, the entire structure is not sufficiently melted. If the cast iron is heated above 1650 ° C, unnecessary energy is wasted. Therefore, it is preferable to heat the nodular cast iron to 1600 to 1650 ° C.

In the molten nodular cast iron, a spheroidizing agent containing about 0.3 to 0.7% of magnesium is added. When the magnesium content is less than 0.3%, the spheroidizing agent has a very small effect, and when it exceeds 0.7%, the effect of the spheroidizing agent is greatly improved. On the other hand, there is a problem that expensive material costs are increased. Therefore, the magnesium mixing ratio of the spheroidizing agent is suitably about 0.3 to 0.7%.

When a spheroidizing agent is added to the molten nodular cast iron, it is spheroidized at 1500 to 1550 ° C. If the spheroidization treatment temperature is less than 1500 ° C., the spheroidization treatment is not performed properly. If the spheroidization treatment temperature is higher than 1550 ° C., the spheroidization treatment effect is not greatly improved, but energy is unnecessarily waste. Therefore, as for spheroidization process temperature, 1500-1550 degreeC is suitable.
