Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a method and device for separating a belt or a dropper (herein referred to as an object to be separated) in a draw ink device for preparing a woven fabric. It is something.

[Prior art and problems to be solved by the invention] In a draw ink device, as a warp preparation process for weaving work, belts are separated one by one from a plurality of belt groups in a predetermined order according to the texture of the woven fabric. Then, the warp threads are pulled into the belt holes of the separated belt. Similar work is also being done on droppers.

Conventionally, the belt or dropper has been separated using various methods as described below, but each method has had its problems.

■ Manual separation method by workers.

This method has low work efficiency because the separation process takes time. Furthermore, since the order in which the belts are separated is very complex, it requires considerable skill for the operator to memorize it. If there is a memory error, the separation order will naturally be messed up.

■ A method of mechanical separation by inserting a spoon-shaped member between special belts with insertion cuts.

Since a special belt is required, a large amount of equipment cost is required. Furthermore, when inserting the knife-like member between the belts, there is a risk that this expensive belt may be damaged.

■ A method of mechanically separating the belt by inserting a separation rod provided with a spiral protrusion into a keyhole formed in the belt, rotating the separation rod and driving a hook six with the protrusion. Specification No. 1983-64760>.

This method also requires a special belt, resulting in high equipment costs.

■ A method of separating a belt or dropper made of magnetic material by attracting it with an attraction magnet (Japanese Patent Publication No. 47-3138
Publication No. 7, Special Publication No. 1972-22145, Special Publication No. 1973
-38021 publication).

According to this method, the above-mentioned problems are largely solved, but the separation device using an attraction magnet has a complicated mechanism and many moving parts, so it takes up a considerable amount of space. Furthermore, each time one belt is separated and conveyed, the attraction magnet must be moved in the X-Y direction, so the separation operation takes time. Furthermore, if the belt becomes magnetized or has an uneven surface condition, it becomes difficult for the attracting magnet to attract or detach, making separation difficult.

SUMMARY OF THE INVENTION An object of the present invention is to provide an innovative method for separating substances to be separated in a draw ink device and an apparatus therefor, which can solve the above-mentioned problems.

[Means for Solving the Problems] In order to achieve the above object, in a method for separating objects in a draw ink device of the present invention, the first object to be separated and the second object from the front in a group of objects to be separated are separated. A method was taken in which the first object to be separated was successively separated from the group of objects to be separated by blowing air into a small gap between the objects and the objects to be separated.

Further, the separation device of the present invention includes a separation nozzle that opens into a small gap between the foremost object to be separated and the second object to be separated from the front in a group of objects to be separated, and a separation nozzle that opens into a small gap that is close to close contact between the object to be separated and the second object from the front in the group of objects to be separated; and an air supply means for sending the air.

[Effect] When air is blown into a small gap between the first object to be separated and the second object to be separated from the front in a group of objects to be separated, the pressure of this air causes a gap between the two liquids to be separated. A force is generated that tries to separate them from each other.

Therefore, the first object to be separated is separated from the group of objects to be separated after the second belt, and on the other hand, the second object to be separated is pressed against the group of objects to be separated and is prevented from falling down.

Further, the separation nozzle and the air supply means in the separation device have the function of blowing air into a small gap between the first object to be separated and the second object from the front in the group of objects to be separated, which are close to each other. do.

[Example] Next, an example of the present invention will be described with reference to the drawings.

In the draw ink device of this embodiment, 16 pairs of upper and lower belt bars 1.2 are horizontally suspended at predetermined intervals, and a plurality of belts 3 are arranged so as to be in close contact with each of these belt bars 1.2. It is passed through to form a belt group 4 of 16 rows. For convenience, only two rows of belt groups 4 are shown in FIG. 4.

The belt 3 of this embodiment is a very general one with no particularity, and has a head part 6 through which the upper belt bar 1 passes, and a lower end part 7 through which the lower belt bar 2 passes, compared to the center part with the belt hole 5. This type has a slightly swollen shape, but of course any other type may be used.

A bottom plate 8 is installed below these belt groups 4 to regulate the lowering limit of the belts 3, and above the belt groups 4 is a compact belt separation device 9 that separates and conveys the belts 3 using air. is provided.

The belt separating device 9 will be described in detail below. A main plate 10 is provided above the upper belt bar 1 and extends perpendicularly thereto, and covers the upper part of each belt group 4 together with the upper belt bar 1. This main plate 1
0 is the separation device feeder 11 every time the belt 3 is separated.
1 (path shown) intermittently to the rear of the belt group 4.

On the lower surface of the main plate 10, 17 air blocks 11 are attached at predetermined intervals, hanging down so as to sandwich the upper portions of the 16 rows of belt groups 4 with gaps between them. In FIG. 4, only three air blocks 11 are shown for convenience. Projecting surfaces 12 are provided at the bottom of both sides of each air block 11.
is provided so that both sides of the portion of the belt 3 directly below the head 6 are covered by the protruding surface 12 with an extremely small gap.

Further, these air blocks 11 are provided with the following nozzles that open into the projecting surface 12.

(2) Separation nozzle 13: This is a flat nozzle for separating the belt 3 from the belt group 4 and conveying it to the warp retraction position. It is provided so as to open almost perpendicularly to a slight gap between the frontmost belt 3a and the second belt 3b from the front in the belt group 4, which are close to each other.

(2) Packing nozzle 14: This is a nozzle for packing the belt group 4 supplied between the air blocks 11 so that it almost comes into close contact with the separation nozzle 13. The air block 11 is provided at two locations, at the center and at the rear end, so as to open diagonally forward and diagonally upward.

(2) Discharge nozzle 15: This is a nozzle for discharging further forward the foremost belt 3a that has been conveyed to the warp retraction position by the separation nozzle 13 and has the warp drawn in further. It is provided at the front end of the air block 11 so as to open diagonally forward and diagonally upward.

The separation nozzle 13 and the discharge nozzle 15 are connected to an air passage 16 that communicates with the main plate 10 through the air block 11 and an air source such as a compressor (the illustrated passage) as a common air supply means. ing. This air supply means may be provided independently for each nozzle 13.15. In addition, the filling nozzle 14 has an independent air flow path 17.
and an air source are connected.

A shaft 18 is rotatably inserted from above near the separation nozzle 13 of the air block 11, and one stopper cam for stopping the belt group 4 is attached to the lower end of the shaft 18 at two locations, upper and lower. . On the other hand, a cylinder 22 is attached to the upper end of the shaft 18 via a lever 20 and a knuckle 21. As the cylinder 22 reciprocates, the shaft 18 rotates, and the stopper cam 19 protrudes from the side surface of the air block 11. It is designed to be pulled in and out.

Further, in front of the main plate 10, a slide shaft 23 extending in a direction orthogonal to the upper belt bar 1 is provided so as to be slidable in the same direction. is installed. Long transport stoppers 25 made of electromagnets (or weak permanent magnets) are attached to these blocks 24.
When the conveyance stopper 25 slides to the front of the belt group 4, the foremost belt 3a separated and conveyed by the separating nozzle 13 is magnetically attracted and stopped at the warp retraction position. At this time, the belt 3a
The belt hole 5 is located within the warp drawing-in nozzle 26, and the warp is drawn in by a warp drawing device (path shown).

In addition, the discharge nozzle 15 of the conveyance stopper 25
An air guide 27 is attached to the air blowing position to adjust the flow of the air and strengthen the discharge force.

The operation of each part of the belt separating device 9, that is, the following:
Separator feeding mechanism, air source for each nozzle 13, 14, 15, cylinder 22, slide shaft 23, conveyance stopper 25
The order of operation of excitation, warp pulling device, etc. is determined by punch card,
It is controlled by a control device (shown in the diagram) using a microcomputer or the like.

Further, the complicated separation order of the 16 rows of belt groups 4 is also stored by the control device, and the belt separation devices 9 corresponding to each belt group 4 are operated in sequence according to this separation order.

Next, the method of separating, conveying, and discharging when separating one belt 3 from one row of belts 4 and the operating order of the belt separating device 9 will be explained with reference to the time chart in FIG. 7. .

■ First, in the initial state, the air sources for the separation nozzle 13, stuffing nozzle 14, and discharge nozzle 15 are all OF.
F, the cylinder 22 is extended and the stopper cam 1
9 is closed.

Next, the air source of the separation nozzle 13 is turned on, and the air source of the separation nozzle 13 is used to detect a small gap (head 6)). This air pressure generates a force between the belts 3a and 3b that tends to separate them from each other.

Subsequently, the slide shaft 23 is slid toward the front, and the conveyance stopper 25 is positioned in front of the belt group 4.

FIG. 1 shows the state at this time.

■ Next, move the cylinder 22 backward and stopper cam 1.
When 9 is opened, the front belt 3a is reliably separated from the belt group 4 after the second belt 3b due to the air pressure from the separation nozzle 13;
is pressed against the belt group 4 to prevent it from falling down.

Subsequently, the separated foremost belt 3a is further pressed forward by the air blown from the belt separation nozzle 13, and is conveyed to the warp retraction position, that is, the position of the conveyance stopper 25.

At this time, since the air block 11 covers both sides of the belt group 4 with gaps, the air is difficult to escape to the sides of the belt 3a. Therefore, air pressure is easily applied to the back surface of the belt 3a, and the belt 3a is reliably conveyed.

In particular, in this embodiment, the protruding surface 1 provided on the air block 11
2 covers both sides of the portion of the belt 3 directly below the head 6 with an extremely small gap, the above effect is further enhanced.

Further, since the belt bar 1 and the main plate 10 cover the upper part of the belt group 4, the air is trapped behind the belt 3a without escaping to the upper part of the belt 3a. Therefore, strong air pressure is applied to the back surface of the belt 3a, and the belt 3a is conveyed more reliably.

The belt 3a conveyed to the conveyance stopper 25 comes into contact with the conveyance stopper 25 and is magnetically attracted thereto.

FIG. 2 shows the state at this time.

In addition, since the conveyance stopper 25 is provided at an angle of approximately 30 degrees when viewed from the plane, the conveyed belt 3a rotates approximately 30 degrees and stops, and the belt hole 5 and the warp drawing nozzle 26
This makes it easier to correspond to the hole in the hole. However, the conveyance stopper 25 may be provided parallel to the front surface of the belt to stop the belt 3a without rotating it.

■ Next, extend the cylinder 22 and stopper cam 19.
After closing and turning off the air source of the separation nozzle 13,
The warp thread drawing device (path shown) is operated to draw the warp threads from the warp thread drawing nozzle 26 to the belt 3a.

Furthermore, the air source of the stuffing nozzle 14 is turned on to remove the belt group 4 between the stuffing nozzle 14 and the air block 11.
Air is blown diagonally forward and upward onto the back surface of each belt 3. Due to the pressure of this air, the belt group 4 from which one belt 3a has been removed as described above is conveyed again to the position of the separation nozzle 13, and packed so as to be in close contact with each other.

In this case as well, since the air block 11, upper belt bar 1, and main plate 10 cover both sides and the upper part of the belt group 4, air is trapped in the back surface of the belt 3 and strong pressure is applied to each belt 3. will be transported reliably.

■ Next, turn off the excitation of the electromagnet of the conveyance stopper 25,
Slide the slide shaft 23 to the back to release the conveyance stopper 2.
5 from the front of belt group 4. Subsequently, the air source of the discharge nozzle 15 is turned ONL, and air is blown obliquely forward and upward from the discharge nozzle 15 to the back surface of the belt 3a. Due to the pressure of this air, the belt 3a into which the warp threads have been drawn is conveyed further forward from the same position and is discharged.

In this case as well, since the air block 11, the upper belt bar 1 and the main plate 10 cover both sides and the upper part of the belt 3a, air is trapped in the back surface of the belt 3a and strong pressure is applied to the belt 3a. are transported and discharged reliably.

This completes the separation, conveyance, and discharge work for one belt. FIG. 3 shows the state at this time.

In this embodiment, since the air guide 27 provided on the conveyance stopper 25 rectifies the air blown from the discharge nozzle 15 forward, the belt 3a can be discharged more reliably.

■ Next, operate the separation device feeding mechanism (not shown),
After the entire belt separating device 9 is sent slightly to the rear of the belt group 4, the operations ① to ② are repeated for another frontmost belt 3a.

The above-mentioned separation, conveyance, and discharge operations proceed automatically for each of the 16 belt groups 4 according to the separation order stored in the control device.

According to the belt separating device 9 of the present embodiment configured as described above, the separating order can be stored in the control device, so that a memorization error will not occur unlike when an operator memorizes the separation order.

Furthermore, since separation and conveyance are performed using air, no special belt is required and it can be applied to any type of belt. Therefore, this greatly contributes to lowering the cost of the draw ink device. Furthermore, there is no risk of the belt being damaged during separation, and even if the belt becomes magnetized or its surface condition undulates, separation and conveyance operations will not be affected.

Furthermore, since the present belt separating device 9 has a simple mechanism and has few moving parts, it can be formed compactly and does not take up much space.

In addition, the belt can be separated and conveyed by simply blowing air onto the belt from the stationary belt separation device 9, and there is no waste of moving the separation device itself in the X-Y direction as in the conventional method. Separation work does not take much time,
High work efficiency.

It should be noted that the present invention is not limited to the configuration of the above-mentioned embodiments, and may be modified and embodied as desired without departing from the spirit of the invention, for example, as described below.

(1) The belt separating device can be provided not only at the top of the belt but also at the center or lower end of the belt.

(2) Separation nozzles can also be provided on both sides of the belt. Further, the separation nozzle may be a round hole or may be one in which a plurality of round holes are arranged.

(3) The present invention is not limited to belt separation, but can also be embodied in dropper separation.

[Effects of the Invention] Since the present invention is configured as described above, it exhibits excellent effects as described below.

The first object to be separated is separated by blowing air into a small gap between the first object to be separated and the second object from the front in the group of objects to be separated (belt or dropper). Since the objects are separated one by one from a group of objects, special objects to be separated are not required, and the objects to be separated are not damaged during separation.

In addition, separation work does not take much time and work efficiency is high. Furthermore, even if the object to be separated is magnetized and its surface condition is undulating, it can be separated reliably.

Furthermore, a separation device equipped with a separation nozzle that opens into the gap and an air supply means that sends air to the nozzle has a simple mechanism and few moving parts, so it can be formed compactly and takes up less space. do not have. In addition, objects to be separated can be separated simply by blowing air onto them from a stationary separation device, and the separation device itself can be
Since there is no waste such as moving in different directions, separation work does not take much time and work efficiency is high.
