DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth feeding device which has a charging section for charging cloth into a main body, and has a charging conveyor for conveying the loaded cloth.

[0002]

2. Description of the Related Art There is known an apparatus for feeding cloths to a section to be conveyed in a spread state. For example, Japanese Patent Publication 8-467
In the case of No. 1, when the tip of the cloth held by the clamp is released, air is ejected from the nozzle toward the inlet on the conveyor, and the air is transferred onto the conveyor with the help of suction means. Having a configuration. In this case, there is a disadvantage that the next cloth delivery operation cannot be started unless the cloth passes through the opening for sucking the input end. In addition, since the cloth receives the suction force near the suction port for the first time, a large suction force is required, and there is a problem that the efficiency is not good.

On the other hand, in Japanese Unexamined Patent Publication No. Hei 8-324858, the feeding end of the cloth can be once passed from the clamp to the suction body. You can start the delivery work. Also,
Work continuity is high because the next cloth can be overlaid on the previous cloth. However, the blowing end of the cloth is blown onto the suction body by the air blow, so that there is a drawback that a wrinkling like a flag flutters and the feeding end is easily disturbed. Even if a system is adopted in which the suction end is sucked by the suction body and guided onto the conveyor, it is not possible to adjust the disturbance at the charging end.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to make it possible to carry out work smoothly in order to improve the efficiency of feeding cloths.

[0005] It is another object of the present invention to prevent disturbance of the cloth to be charged, particularly at the leading end thereof, and to automatically load the cloth with high quality.

[0006]

In order to solve the above-mentioned problems, the present invention provides a clamp member which holds an input end of cloth at the upper front end of an input conveyor and separates the input end at the time of input.
A receiving part which is movable in the front-rear direction on the conveying surface of the input conveyor, protrudes from the front end of the input conveyor at the time of forward movement, and is retracted at the time of retreat, and has a planar portion for receiving the input end of cloth separated from the clamp member. A member, an acceleration member for forming an airflow accelerating portion that is widened forward and narrowed rearward between the receiving member, and a suction mechanism having an injection nozzle that injects airflow rearward at the airflow accelerating portion; A means is provided in which a cloth feeding device is constituted by a driving unit of a receiving member that allows the member to approach the charging conveyor and transfer the cloth from the charging end to the charging conveyor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cloth feeding apparatus A according to the present invention.
Has an input section 12 for inputting the cloth 11 into the main body 10 and includes an input conveyor 13 for transporting the input cloth 11.

When the loading section 12 is located at a position where the operator's hand is difficult to reach, such as the upper part of the main body, a transfer device B for transporting the cloth 11 from the worker's position to the loading section 12 can be attached. Therefore, in a broad sense, the transfer device B also constitutes the cloth feeding device according to the present invention. When the transfer device B is included in a part of the cloth feeding device, the transfer device B
And the operation of the input device main body can be selected in conjunction with each other. The present invention has the above-described interlocking configuration as described later.

First, the main body of the charging device A will be described. The charging device includes a clamping member 14 which holds the charging end of the cloth 11 on the upper front end of the charging conveyor 13 and separates the held charging end at the time of charging. Have. Therefore, the clamp member 14 is disposed in the loading section 12 and releases the holding of the cloth 11 at this position. Further, since the clamp member 14 holds the cloth 11, when the transfer device B is combined as described above, it follows the transfer device B.

The clamp member 14 has a fixed portion 15 and a movable holding portion 16 for holding cloths therebetween. The clamping operation and the releasing operation of the clamping member 14 can be remotely controlled by a controller (not shown).
Further, it can also be linked with the transfer device B in the preceding stage, the receiving member 18 and the suction mechanism 26 in the subsequent stage.

After leaving the clamp member 14, the cloth 11 is once transferred to the receiving member 18. Receiving member 1
Numeral 8 is movable in the front-rear direction on the conveying surface of the charging conveyor 13, and is configured to exit before the front end 17 of the charging conveyor 13 when moving forward and to retract after the front end when moving backward. When moving forward, the tip 19 of the receiving member 18
It is desirable that the loading section 12 contacts the cloth 11 at the position 20 hanging from the clamp member 14 and further pushes the cloth 11 away from the front end 17 of the conveyor (see FIG. 5). As a result, the input end 21 of the cloth 11 comes behind the tip 19 of the receiving member 18. For this reason, it is easy to guide the input end 21 of the cloth 11 onto the receiving member 18 without blowing it away as in the related art.

Further, the receiving member 18 has a planar portion 22 for receiving the input end 21 of the cloth 11 separated from the clamp member 14. The planar portion 22 is a surface that receives the input end 21 approaching from above, and is, in effect, an upward facing surface.
Therefore, it is desirable that the surface be suitable for accelerating the airflow, for example, a surface having low resistance and not disturbing the flow. The planar portion 22 covers most of the upper surface side behind the front end 19 of the receiving member 18. The front end 19 can be provided with a non-slip against the cloth 11.

Above the receiving member 18, the accelerating member 2
3 are provided. The receiving member 18 and the accelerating member 23 form an airflow accelerating portion 24 that expands forward and narrows rearward between them. The air flow is accelerated by squeezing the air flow cross section from upstream to downstream so that the input end 21 of the cloth is sucked. It is injected. The negative pressure suction effect on the cloth 11 may be generated at the time of receiving, that is, when the receiving member 18 is at the forward position or in the vicinity thereof. Therefore, the accelerating member 23 may be installed at a position where the airflow accelerating part 24 can be formed between the accelerating member 23 and the receiving member 18 at the advanced position as in the illustrated embodiment. However, the acceleration member 23 is provided beforehand integrally with the receiving member 18 so as to form the airflow acceleration portion 24 having the tapered cross section, and the injection nozzle 25 is also provided integrally in the airflow acceleration portion, so that the entire suction mechanism 26 can be moved back and forth. It can be easily configured to be movable in the direction.

The receiving member 18 is moved closer to the loading conveyor 13 so that the loading end 21 of the cloth 11 can be transferred to the loading conveyor 13.
Is provided. The drive unit 27 includes a drive source 28 that supplies power for moving the receiving member 18 forward and backward on the transport surface of the input conveyor 13, and a transmission member 29 that transmits the power to the receiving member 18.

In the embodiment shown in the drawing, the rear end of the receiving member 18 is relatively rotatably connected to the front end of an arm 30 by a shaft 31. The arm 30 is swingable in a pendulum manner about a pivot point 32. The illustrated receiving member 18 has a guide wheel 33 near the front end, and the guide wheel 32 can be guided along guide rails 34 provided on both sides of the conveyor, and transports the front end 19 of the receiving member 18 to the input conveyor 13. The cloth 11 is always placed at a fixed position with respect to the surface, so that the cloth 11 can be transferred more stably.

When the input end 21 of the cloth 11 is separated from the clamp member 14, an air push nozzle 35 for jetting air is moved forward of the input section 12 in order to smoothly shift to the suction mechanism 26. Can be provided. The nozzle 35 is not indispensable and can be omitted.

Next, the transfer device B for transferring the cloth 11 to the loading section 12 will be described. As already explained partially, the transfer device B is provided immediately before the charging section 12 for constituting a part of the charging apparatus A.

After the worker attaches the tip of the cloth 11 to the transfer member 41, the transfer device B
1 is a device for transferring the sheet 1 to the input section 12 and passing it to the clamp member 14. The transfer member 41 can be moved almost vertically along a support 42 extending from the upper portion to a work position such as the front and lower part, and the cloth 11 is transferred between the transfer member 41 attached to the moving mechanism and the transfer member 43. And a clamp member 44 to be held therebetween. The clamp member 44 is biased in the clamping direction by the biasing means 45, and when the operating end 46 is pressed against the biasing means 45, the downward clamping port 47 can be opened.

The transfer member 41 is attached to a moving body 48, and the moving body 48 is attached to a support 42 by a fixed moving path 49.
Along the same route 49
Cloth 1 to the clamp member 14 disposed above
1 (the tip) can be handed over. For this purpose, in the embodiment, the transfer member 41 is formed in a bifurcated shape, and the clamp member 14 enters the space between the bifurcated shapes, and the two members 14 and 41 are overlapped in the input unit 12. The structure is such that the cloth 11 is handed over. See FIG. 2 and FIG.

Reference numeral 50 denotes a driving unit for driving the holding unit 16 of the clamp member 14. The holding unit 16 is opened before the delivery member 41 overlaps the clamp member 14, and overlaps the cloth 11.
Is closed when the leading end portion thereof comes between the fixing portion 15 and the holding portion 16, and holds the cloth 11. Reference numeral 51 denotes a sandwiching release member that engages with the clamp member 44 to release the cloth 11 after passing it over. The member 51 can be configured as shown in the figure as a slope as a kind of cam on the movement line of the transfer member 41. Therefore, remote judgment is not necessary.

First, the worker attaches the leading end of the cloth 11 to the delivery member 41 at a position where it is easy to work. By the control device (not shown), the moving device B operates to pass the tip of the cloth 11 to the clamp member 14 and
Numeral 1 is a state in which it hangs down just before the input section 12.
This is the state shown by the solid line (20) in FIG. Thereafter, the receiving member 18 advances according to a predetermined program or by a signal from the sensor device, and the line (2)
In the hanging state, the cloth 11 is moved to the front of 0).

Next, the suction mechanism 26 is operated to generate a negative pressure flow 52 in the airflow accelerating section 24, and the cloth 11 separated from the clamp member 14 with the help of the air pushing nozzle 35 which is operated as required. Is sucked into the airflow accelerating unit 24. FIGS. 6A and 6B show this state. In the suction mechanism 26, a laminar negative pressure flow 52 is formed in a throat portion surrounded by the upper surface of the receiving member 18 and the lower surface of the acceleration member 23, without disturbing the input end 21 falling away from the clamp member 14. , Receiving member 1
8 can be placed on the planar part 22. Since the cloth 11 is drawn on the receiving member 18 by negative pressure, no air is interposed between the cloth 11 and the occurrence of wrinkles and turbulence is prevented.

Thereafter, the receiving member 18 is moved to the planar portion 22.
Then, the cloth 11 is retracted with the cloth 11 placed up to the non-slip end 19, and moves to a position retracted from the front end of the charging conveyor 13. Here, the cloth 11 comes into contact with the loading conveyor 13 and the receiving member 18 is retracted to the maximum, so that the loading end 21 is stretched by the non-slip end 19 and placed on the loading conveyor 13, and the loading of the cloth 11 is completed. I do. Since the input end 21 originally having no wrinkles or disturbance is further stretched, a very high-quality input operation is realized.

[0024]

Since the present invention is constructed and operates as described above, it is provided with a receiving plate for temporarily receiving the input end of the cloth on the input conveyor, and the air flow formed by the receiving plate and the accelerating member. A negative pressure is generated by injecting airflow from the injection nozzle to the accelerating unit and negative pressure can be suctioned from the input end of the cloth, so that wrinkles and turbulence are generated at the input end by a simple and trouble-free configuration. In addition, the cloths are loaded and the cloths are temporarily stored on the receiving board, so that the next cloths can be delivered regardless of the preceding cloths, and can be stacked on the preceding cloths. Therefore, there is an effect that the work efficiency of the input can be significantly improved.
