Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stocking cloth processing apparatus, and more particularly, to supplying stocking cloth in a fixed posture toward a mounting arm that automatically mounts the stocking cloth on a biting member of a rise sewing machine. And a stocking cloth treating apparatus capable of delivering the stocking cloth with the welt portion opened on the mounting arm.

[0002]

2. Description of the Related Art To manufacture panty hose,
The inner crotch part that becomes the panty part is sewn by the crotch sewing machine by aligning the welt parts of the two tubular stocking materials knitted from the raw yarn with the left and right, and then each toe part of this stocking material is sewn by the toe sewing machine By doing so, one pantyhose is obtained.

The pantyhose which has completed the sewing work is further processed into various products such as dyeing, set finishing and packaging.

As mentioned above, the pantyhose is manufactured through the two processes of the rise sewing and the toe sewing.
As a sewing machine for performing both of these processes, an automatic crotch sewing machine (Japanese Patent Publication No. 52-8734) and an automatic toe sewing machine (Japanese Patent Publication No. 55-37272) developed by the present applicant have been widely put into practical use. There is.

Further, these are the first sewing machine and integrated sewing method and device (Japanese Patent Publication No. 61-21430) for connecting the two sewing machines to each other in order to make the pantyhose sewing process efficient and labor-saving. Device for automatically attaching stocking cloth to the biting member of the riser
259892) is also well known.

As described above, the consistent sewing method and apparatus of Japanese Patent Publication No. 61-21430 provide an excellent feature that two operators are required by one, and the method disclosed in JP-A-1-259892. In the automatic mounting device, the heavy labor of mounting the welted part of the stocking cloth by spreading it from the inside with both hands was eliminated.

[0007]

However, even with the automatic mounting apparatus of the above-mentioned Japanese Patent Laid-Open No. 1-259892, it is still necessary for the operator to perform an auxiliary work.

This is because it is difficult to handle the stocking material having a soft property with a machine, and in particular, it is necessary to supply the stocking material in a certain posture and to surely open the welt portion without mistakes in preparation for the mounting work. It is extremely difficult to handle it, and this is hindering the complete automation (unmanned operation) of the pantyhose sewing process.

Therefore, an object of the present invention is to supply a stocking material to be sucked and conveyed in a fixed posture to a welt opening mechanism that opens the welt portion of the stocking material with an intake air flow. It is an object of the present invention to provide a stocking cloth processing apparatus capable of completely automating (unmanning) the pantyhose sewing process by connecting the above to the conventional mounting arm described above.

[0010]

In order to solve the above-mentioned problems, the invention of claim 1 comprises a stocking cloth supply mechanism and a stocking cloth welt opening mechanism, wherein the supply mechanism is one sheet. The stocking material addressed to the stocking material is successively conveyed through the pipe by the intake air flow, and is formed so that the welt side of the stocking material is controlled so that the welt side of the stocking material always comes first during the conveyance. The mechanism is formed so that the stocking material supplied with the welt portion first opens the welt portion in the pipe of the opening mechanism by the action of the intake air flow, and the opening portion is delivered onto the mounting arm. The configuration is adopted.

According to a second aspect of the present invention, in the first aspect of the present invention, the supply mechanism is capable of moving up and down in front of an end of the stocking material receiving side of the pipe, and has a dough grip for lifting the stocking material in the lower tray. The arrangement is such that a supply pipe that moves forward and backward with respect to the ascending / descending portion of the cloth gripper is connected to the cloth receiving side end of the pipe.

Here, the supply mechanism is provided with a portion for selecting the stocking material sent first by the welt part and the stocking material sent first by the toe part in the middle of the pipe for sucking and carrying the stocking material. The stocking fabric sent with the welt part first is conveyed along the main pipe of the pipe, and the stocking fabric sent with the toe part of the pipe is returned to the main pipe of the pipe by passing through the backward pipe. The posture is changed so that the welt portion comes first, so that the stocking material can be surely supplied to the welt portion opening mechanism with the welt portion first.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the stocking cloth processing apparatus comprises a stocking cloth feeding (conveying) mechanism X at a front stage and a welt opening mechanism Y at a rear stage, and the feeding mechanism X conveys the stocking dough S.

The tray 51 is, for example, a turntable 5
A large number of them are arranged in a circle on the la 1a so as to intermittently stop immediately below the cloth grip 50.

A horizontal supply pipe A which is moved forward and backward by the expansion and contraction of the cylinder A'with respect to the ascending and descending portion of the cloth grip 50 is connected to the cloth receiving side end of the pipe B, and is lifted by the cloth grip 50. The stocking cloth S is approached to the lower part and the cloth S is sucked into the pipe B.

In order to reverse the posture of the stocking cloth S sent with the toe portion to a position upstream of the branch connection portion of the suction pipe C in the middle of the pipe B, both ends of the reverse feed pipe B '. Are connected at upstream and downstream positions.

The welt portion opening mechanism Y connects the pipes G and F and the double pipe H coaxially, and each of them is driven by an appropriate driving means such as a cylinder or a feed screw along the rail 71 on the table 70. The pipe I is arranged so as to move in the axial direction, the end of the pipe G is connected to the suction source 54 via the pipes L and K, and the inside of the outer large diameter pipe H ₁ of the double pipe H is telescopically connected. And J are connected to the suction source 54.

An elevating pipe E is connected to the tip of the pipe B so as to move up and down by a cylinder E ', and the upper end of the branch pipe F ₁ of the central pipe F in the welt opening mechanism Y faces directly below the elevating pipe E to elevate. By lowering the pipe E, the pipes B and F are connected.

The double pipe H is an outer large diameter pipe H ₁
A small-diameter pipe H ₂ that communicates with the pipe F is housed inside the pipe, and a plurality of fins 5 are provided between the large-diameter pipe H ₁ and the small-diameter pipe H _2.
5 is provided, the tip of the large diameter pipe H ₁ can be freely opened and closed by a lid 56, and a spherical projection 56 ′ is provided on the inner surface of the lid 56, and a mounting arm 60 is provided in front of the double pipe H. I will come.

The stocking material supply mechanism X and the welt opening mechanism Y automatically supply the stocking material S, supply it, change its posture, and deliver it from the double pipe H to the mounting arm 60 by controlling the intake flow. For this purpose, the sensors 1 to 14 are sequentially arranged in the vicinity of the up and down movement of the dough grip 50 and in the middle of each pipe where the stocking dough S needs to be detected. In the middle of the pipes G and F of the welt opening mechanism Y, comb-shaped shutters 21 to 28 are sequentially provided at locations where the stocking material S needs to be conveyed and its posture is controlled, and the outside air provided in the middle of the pipe B is further provided. A part of the inlet B and the pipe B where the stocking material S needs to be conveyed and the posture of the stocking S needs to be controlled, and the pie of the welt opening mechanism Y. F, the valve 3 to each of the middle of K and I
1 to 42 are provided.

The comb shutters 21 to 28 are shown in FIG.
As shown in FIG. 2, the pipe is divided in a coaxially arranged manner in the case 81, and comb-shaped shutter plates 82, 82 are provided in the case 81 at positions on both sides of the pipe 81 so as to sandwich the axial center of the pipe, respectively. At 83, the center of the pipe is used as a reference so that it can be opened and closed so that it can be moved toward and away from the pipe. When the pipe is opened, the intake flow of the pipe and the stocking fabric are allowed to pass freely. It is structured to stop.

Further, as shown in FIG. 13, the valves 31 to 42 have a pair of valve plates 85, 85 on both sides inside the case 84, and cylinders 86, 8 similar to the comb-like shutter.
It is provided so as to move at 6, and the intake air flow and the stocking material can freely pass when it is opened, and the air flow of the pipe is blocked when it is closed.

The valves 31, 32, 37 and 38 play a role of allowing the outside airflow to flow into the pipe when the valves are opened.

As for only the valve 43 provided on the pipe F of the welt opening mechanism Y, as shown in FIGS. 14A and 14B, a cylindrical valve 87 is rotatably fitted on the outside of the pipe F. 14, a plurality of air holes 88 and 89 are provided at equal intervals in each of the pipe F and the cylindrical valve 87, and the cylindrical valve 87 is rotated by the cylinder 90 to the closed position.
As shown in (A), the air hole 88 of the pipe F is closed, and
When the cylindrical valve 87 is set to the open position as shown in FIG. 14B, the air holes 88 and 89 communicate with each other so that the outside air can flow into the pipe F.

In the processing apparatus, two sets are arranged in parallel and two stocking materials required for sewing panty hose are simultaneously conveyed to open the welt portion.

The processing apparatus of the present invention has the above-mentioned structure. Next, a processing method using this processing apparatus will be described.

(Initial State) As shown in FIG. 1, the cloth grip 50 is at the rising standby position, and the comb-like shutters 21, 2 are provided.
3, 26 and 28 are in the open state, 22, 24, 25 and 27 are in the closed state, and only the valve 33 is in the open state and the others are in the closed state.

Further, the supply pipe A is in the retracted position, the elevating pipe E is in the lowered position and connected to the branch portion F ₁ of the pipe F, the pipes F, G and the double pipe H are in the retracted position, and the lid 56
Is closed.

The cloth grip 50 descends (from the above initial state), and the sensor 1 detects the presence or absence of the stocking cloth S in the tray 51. (If there is a dough, it will grab and operate to grab the dough. If there is no dough, the dough grab 50 will rise and wait for the next tray)

The dough grip 50 holding the dough moves up and returns to the original ascending standby position by the return sensor 2 to detect the presence or absence of the taken dough, and the sensor 2 detects in the grip state of FIG.

The sensor 2 does not detect in the gripped state of FIG. In this case, the material grip 50 is released and the material S
Is dropped into the tray 51, and then the gripping operation is repeated. If this gripping work is not detected even after performing it twice, wait for the next tray.

When the sensor 2 detects the cloth S, the supply pipe A moves forward (the position indicated by the alternate long and short dash line in FIG. 2), and the cloth grip 50
Also descends. The sensor 3 detects the edge of the cloth when the cloth grip 50 descends.

The valve 36 is opened from the closed state by the detection of the sensor 3, and the intake flow from the suction source 52 passes through the pipes C and B shown by the arrows in FIG. 1 and acts on the tip of the supply pipe A.

As a result, the dough S descending together with the dough grip 50 is sucked into the supply pipe A from one end thereof, reaches the pipe B, and is detected by the sensor 4. (FIG. 4
State) It is not known which of the welt part and the toe part is sucked in first.

The detection of the sensor 4 releases the grip of the cloth S by the cloth grip 50. By this release, the cloth is sucked into the pipe B, and the shutter 2
Stop by 2. The suction works when the cloth is clogged in the pipe B. (Figure 4 chain line)

At this time, the sensor 5 detects the cloth S, and the grip 50 returns to the raised position and the supply pipe A returns to the retracted position by this detection.

The detection of the sensor 5 is performed by opening the shutter 21 from the open position, closing the shutter 22 from the open position, and opening the valve 31 from the closed position.

When the shutter 21 is closed, the cloth S is held in the middle, and when the shutter 22 is opened, the front portion of the cloth S gripped by the shutter 21 (the cloth portion between the shutters 21 and 22) is guided along the pipe B. 5 and the valve 31 is opened, and the outside air flows into the pipe B to help the intake air flow. (Because the fabric S is clogged at the shutter 21 part, it is difficult for air to flow)

Thus, when the cloth S is gripped by the shutter 21 and the front portion thereof is stretched, the sensors 6, 7
Is detected to determine whether the welted part or the toe part is first.

That is, when the welted portion and the toe portion of the cloth are compared, the amount (volume) of the welted portion side is more than twice as large as that of the toe portion side because of the rubber knitted portion and the panty portion.

Therefore, the amount (length) of the cloth S clogged between the shutters 21 and 22 is smaller in the welt portion and larger in the toe portion.

As a result, when the welt side precedes, for example, the amount (length) of the stretched cloth reaches only the detection range of the sensor 6, as shown by the broken line in FIG.

On the contrary, when the toe side precedes, the amount (length) of the stretched material is large and reaches the one-dot chain line in FIG. 5 so that both sensors 6 and 7 eventually detect it.

As described above, whether the welt portion of the fabric S is the first or the toe portion is first is determined when the sensor 6 alone detects the fabric and when both the sensors 6 and 7 detect the welt. I try to judge the condition such as the toe.

When only the sensor 6 detects and the welt portion is judged to be first, the shutter 21 is opened and the valve 3
1 closes.

As a result, the cloth S is sucked and conveyed in the pipe B through the path shown in FIG. 6, and stopped by the shutter 24 in the closed state.

During this intake air conveyance, the valve 32
Is opened and the outside air is allowed to flow into the pipe B from there, so that the intake flow is weakened and the conveyance speed of the cloth S is slowed down accordingly.

This is for preventing the dough stopped by the shutter 24 from being in a dumpling state, and by controlling the opening amount of the valve 32, an arbitrary conveying speed can be obtained. (If the dough S becomes extremely dumpling, there will be a problem that the dough will be clogged in the pipe.)

When both the sensors 6 and 7 detect that the toe portion is first, the shutter 21 is opened, the valve 31 is closed, and the shutter 23 is closed.

As a result, the cloth S is sucked and conveyed in the pipe B and stopped by the shutter 23 in the closed state. (State of FIG. 7)

When the cloth is stopped by the shutter 23, the cloth 9 is detected by the sensor 9.

To detect the sensor 9, the valve 33 is closed,
By opening valve 35 and opening valve 32,
The intake flow flows as shown by the arrow in FIG. 7, and as a result, the fabric S stopped by the shutter 23 is sucked and conveyed in the pipe B ′ with the rear welt end first, reaches the shutter 24, and stops. . (State of chain line in FIG. 7) Same as the state where the above-mentioned welt portion is conveyed first.

The intake air flow flowing through the pipe B'is weakened by opening the valve 32, and the conveying speed of the cloth S becomes slow.

As described above, the cloth S conveyed with the toe portion first reaches the shutter 24 with the welt portion first by the switching action of the shutter and the valve.

In this way, the shutter 24 is provided for the cloth S that has been conveyed either by the welt portion or the toe portion first.
When it reaches, the welting section will stop first.

When the cloth S stops, the sensor 8 detects the cloth S next.

The sensor 8 detects the valve 34,
38 and 39 are closed to open, and the valve 36 is open to closed.

By the opening / closing operation of these valves, the intake flow that has been flowing through the pipe C up to that time is now shown in FIG.
As indicated by the arrow line, the intake flow acts from the pipe B after the valve 34 through the pipe D. Then, when the shutter 24 is opened from the closed state, the cloth S stopped there is further sucked and conveyed in the pipe B with the welt portion first, and the shutter 25 near the end of the pipe B. Be stopped. In this case, since the valve 38 is opened, the outside air flows thereinto, which weakens the intake flow, slows down the conveyance speed of the cloth S, and the cloth stopped at the shutter 25 does not enter the dumpling state.

The fabric stopped by the shutter 25 is then detected by the sensor 10.

The detection by the sensor 10 returns all the shutters and valves of the stocking material supply (conveyance) mechanism to the original initial state and prepares for the next material supply operation.

That is, the shutter 2 which has not been operated yet
5, all the shutters and valves except the valves 37 and 40 are returned to the initial state, and the intake flow does not flow in the pipe B.

The cloth S stopped by the shutter 25 is
If the place is a temporary standby position and the welt opening mechanism is still in operation, it waits on the spot.

When the work of the welt opening mechanism is completed and a command for supplying the cloth S is issued from the mechanism, the valve 42 on the opening mechanism side is first halved based on the command.
When opened, the intake air flow from the suction source 54 is pipe I → pipe J → double pipe H large diameter pipe H ₁ to small diameter pipe H ₂
→ Pipe F → Acts on the lifting pipe E (Fig. 1) connected to the branch F ₁ of the pipe F. Since the valve 42 of this intake air flow is half open, the suction force of the intake air flow is halved.

When the intake air flow acts on the lift pipe E, the valve 40 and the shutter 25 on the supply mechanism side are opened next, and as a result, the intake air flow acts on the pipe B to move the cloth S to the welt opening mechanism side. The fabric S is sucked and conveyed to the pipe F,
Is stopped by the shutter 27 with the welt portion first.
(State of FIG. 9)

At this time, the valve 37 is also opened to allow the outside air to flow into the pipe B.

When the cloth S is conveyed into the pipe F and stopped by the shutter 27, the cloth S is detected by the sensor 11 next.

The sensor 11 detects the shutter 25 and the valve 3 on the side of the stocking material supply mechanism X.
7 and 40 are closed, and after that, the operation is started from the above-described cloth grip 50, the next cloth S supply operation is started, and the cloth S having the welt portion first is made to wait on the final shutter 25.

On the other hand, on the side of the welt opening mechanism Y, the shutter 26 is first closed, and the cloth S stopped at the shutter 27 is held in the middle. Then valve 4
2 is closed to stop the intake action. And then valve 4
1 is opened to cause the intake flow of the suction source 54 to act on the inside of the pipe F from the pipe K through the pipe L and the pipe G (arrow line in FIG. 1). The toe side of the grasped cloth S is stretched in the pipe L direction as shown by the alternate long and short dash line in FIG. The cloth S thus stretched is then detected by the sensor 12.

The sensor 12 detects that the shutter 28 is closed and the cloth S is gripped near the toes.

When the cloth S is gripped by the shutter 28,
The valve 41 is closed to shut off the intake air flow.

Then, when the valve 42 is opened again, the intake flow from the suction source 54 (this time, fully opened) is again acted on the double pipe H side into the pipe F through the pipe I and the shutters 26 and 27 are closed. When the cloth S is opened, the welt side of the cloth S becomes a free state, and the welt side is stretched toward the front end direction of the pipe F by the intake action. At this time, the valve 43 also changes from the closed state to the open state to allow the outside air to flow into the pipe F.

Since the cloth S to be stretched is gripped by the shutter 28 near the toes, and the valve 42 is also fully opened, the cloth S is stretched over almost the entire length (from the legs to the welts). It is stretched to the full. (Figure 1
0 state)

As described above, the dough S supplied into the pipe E is once stretched in the toe direction, and the part near the toes is grasped, and this time, on the contrary, the dough S is stretched in the welt direction. In addition to removing wrinkles, the length of the final stretched fabric will always be stretched with a constant dimension even if the fabric has different lengths, and as a result, the next welt will be stable. Part opening work can be performed.

When the fabric S is stretched between the pipes G and F in this way, the pipe G is then advanced in the direction of the double pipe H by an appropriate driving means, so that the stretched fabric S is expanded. Of the double pipe H enters the small end pipe H ₂ of the double pipe H and is detected by the sensor 13.

The detection of the sensor 13 stops the advance of the pipe G. Further, the shutters 26 and 27 are closed to grip the stretched cloth S near the center of the legs. After that, the shutter 28 is opened, and the fabric S that has continued until then
By releasing the grip near the toes, the cloth S portion in the pipe G direction from the shutter 26 is drawn into the pipe F by a suction action. (State of FIG. 11) After that, the pipe G is retracted and returned.

Thereafter, the elevating pipe E is further raised to release the connection with the branch portion of the pipe F, and the pipe F is advanced toward the lid 56 of the double pipe H so that the pipe F projects from the end. The welt portion facing the small diameter pipe H ₂ is moved to the end of the small diameter pipe, and by this movement, the welt portion moves from the small diameter pipe H ₂ to the large diameter pipe H ₁ and the small diameter pipe H 2. _By the action of the plurality of fins 55 provided on the outer peripheral surface of ₂ and the spherical projections formed on the inner surface of the lid 56, they are flipped outward at the end of the small diameter pipe H ₂ and, as a result, the outside of the small diameter pipe H ₂ It will be turned over on the periphery.

When the welt portion is flipped outward by the intake air flow, the welt portion enters the spherical projection formed on the lid 56, and the large diameter pipe H ₁ and the small diameter pipe H are inserted.
Welt portion by the intake flow of the formed passage between the _two is raised turning outwardly, it will be placed over the inside out shape on the end outer periphery of the small diameter pipe H _2, large-diameter pipe H ₁ this time The plurality of fins 55 having different lengths provided between the small-diameter pipe H ₂ and the small-diameter pipe H divide the passage finely, and the intake flow acting on the divided passages is equalized to the outside of the welt portion. Pipe H is the flipping operation
_It is designed to be performed without any trouble without biasing to one of the _two .

When the welt end is turned up on the small diameter pipe H ₂ , the sensors 14 and 14 detect this portion.

The detection by the sensors 14 and 14 causes the forward movement of the pipe F to be stopped, the valve 42 to be closed to interrupt the suction action, the lid 56 to open, and the shutters 26 and 27 to open.

As a result, the cloth S has its welt portion turned up over the small diameter pipe H ₂ and the other cloth portions (from the legs to the toes) are in a free state.

After that, the double pipe H (large diameter pipe H ₁ ,
The small-diameter pipe H ₂ is integrated, and the mounting arm 60
When it reaches, the welt portion is delivered onto the mounting arm 60. (Fig. 11 two-dot chain line state)

In this way, when the welt portion of the cloth S is transferred onto the mounting arm 60, the double pipes H and F are then retracted and returned to their original positions, and the lid 56 is closed. The elevating pipe E also descends and is connected to the branch portion of the pipe F. Further, the shutter 27 is closed, and the entire welt opening mechanism is returned to the initial state, and the work of one cycle is completed.

Thereafter, the same work is repeated. The welt portion, that is, the stocking cloth S, delivered to the mounting arm 60 is then mounted on the bite member of the crotch sewing machine by the action of the mounting arm 60. Since it has already been disclosed in Kaihei 1-259892, this explanation is omitted.

[0086]

As described above, according to the present invention, the stocking material which is sucked and conveyed through the pipe is supplied to the welt opening mechanism by controlling the posture so that the welt part comes first, and the welt opening mechanism supplies the intake flow. Since the welt portion is surely opened by utilizing this and the opening portion is automatically delivered to the mounting arm, the pantyhose sewing process is fully automated by connecting the device of the present invention to the conventional automatic mounting device ( Unmanned) can be achieved.
