Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a cotton-like material feeding device, and more particularly to a device for feeding cotton-like material entangled in an at random manner while averaging the same.

[Conventional technology]

2. Description of the Related Art Conventionally, for example, an apparatus for supplying a cotton-like material which is a raw material of a nonwoven fabric is shown in FIG.

This is to supply the cotton-like material 30 manufactured by a so-called melt blow method or a method of splitting a film into strips into fine fibers to the next step, for example, a non-woven fabric forming step. It is used in order to improve the quality of the non-woven fabric manufactured in a later step by supplying the cotton-like material to a predetermined thickness at the time of supply and delivering it in a uniform state without vortex-like lumps.

Briefly explaining the structure, the cotton-like material 30 conveyed by a conveyor or the like from the cotton-like material manufacturing process is carried in from a hopper 31,
It is transferred horizontally by a conveyor 32 installed at the bottom of the hopper 31. An endless track 34 is slantedly arranged at the end of the conveyor 32. A large number of claws (spike lattices) 33 for locking the cotton-like material 1 are provided on the endless track 34. As a result, the cotton-like material 30 sent from the conveyor 32 is hooked on the claw 33 and transferred in the direction of arrow F. A fly comb 35 is rotatably arranged near the endless track 3. This fly comb 35 is constructed by providing an arc-shaped comb portion 37 at the other end of an arm 36 whose one end is pivotally supported (38).

Then, the cotton-like material 30 transferred on the endless track 34 is plowed by the fly comb 35 to average the dispersed state of the cotton-like material 30 and send it to the next step.

[Problems to be solved by the device]

However, in the above-described conventional device, the amount of the cotton-like material 30 caught on the claw 33 is sent to the fly comb indefinitely, so that the cotton-like material 30 is wound around the fly comb shaft (38) or climbs on the arc-shaped comb portion 37. In some cases, it was necessary to stop the device each time and remove the cotton-like material 30. Moreover, even if the device does not stop, the uniformity of the cotton-like material 30 is greatly impaired in the state where the cotton-like material 30 is accumulated in the fly comb 35, so that the quality of the nonwoven fabric or the like manufactured in the next step is deteriorated. There is a problem.

The present invention has been made in view of the above-mentioned matters, and a cotton material that does not wrap around the axis of a fly comb or ride on an arc-shaped comb portion and that can maintain the uniformity of the cotton material. It is a technical object to provide a material supply device.

[Means for Solving the Problems]

In order to solve the above technical problem, the present invention is provided with a number of claws 2 for locking the cotton-like material 1 and an inclined endless track 3 which is placed close to the endless track 3. And a rotatable fly comb 4 is arranged, and the cotton-like material 1 transferred on the endless track 3 is plowed by the fly-comb 4 to average the dispersed state of the cotton-like material 1 and feed it. The device has the following configuration.

That is, the fly comb 4 has an arm 5 whose one end is pivotally supported.
An arc-shaped comb portion 6 is provided at the other end of the.

A protective plate 7 is provided between the tip of the comb portion 6 and the arm 5 for preventing the cotton-like material 1 from riding up.

Further, a baffle plate 8 close to the endless track 3 is provided on the upstream side of the endless track 3 with reference to the fly comb 4 as a cotton-like material feeding device. In the next step in which the cotton-like material is supplied by this apparatus, a nonwoven fabric is manufactured by needle punching, embossing, nip rolls and the like.

The height (clearance) of the baffle plate 8 from the surface of the endless track 3 depends on the thickness of the cotton-like material to be supplied, but the height (clearance) between the comb 6 and the surface of the endless track 3 (higher or lower).・ And the degree is specifically).

Further, it is desirable that the baffle plate 8 is installed so that it can be moved up and down and the angle thereof can be changed. Further, a sensor is provided on the supporting portion of the baffle plate 8 to detect the resistance of the cotton-like object to automatically adjust the height, or to rotate and vibrate the baffle plate 8 to shake the tangled cotton-like object. Further labor saving can be achieved by providing a device such as a dropping device.

[Action]

The cotton-like material 1 is hooked on a large number of claws 2 provided on the endless track 3 and goes up the slope of the endless track 3. First, the cotton-like material 1 comes into contact with the baffle plate 8 and the passing thickness thereof is limited to the distance between the baffle plate 8 and the surface of the endless track 3. The cotton-like material 1 reaches a fly comb 4 which is provided close to the endless track 3 so as to be rotatable, and the comb portion 6 of the fly-comb 4 averages the dispersed state of the cotton-like material 1. At this time, the cotton-like material 1 is a fly comb 4
However, the protection plate 7 provided between the tip of the comb 6 and the arm 5 prevents the ride. As a result, the cotton-like material 1 is smoothly fed,
The cotton-like material is delivered with a uniform thickness and uniform properties.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 and 2. The same parts as those described in the above-mentioned conventional example are designated by the same reference numerals, and the description thereof will be omitted.

This embodiment is used for a part of the manufacturing process of the electret original fabric, and supplies the cotton-like material 1 carried in from the fiber manufacturing process (not shown) to the next process. The cotton-like material 1 carried in from the fiber manufacturing process is transferred by a conveyor 32 arranged at the bottom of the hopper 31, and the endless track 3 is arranged at the end of the conveyor 32. This endless track 3
A large number of claws (spike lattices) 2 for locking the cotton-like material 1 are provided on the outer side of the slant. The endless track 3 is driven in the direction of the arrow to pull up the cotton-like material 1.

A fly comb 4 is arranged above the endless track 3, and the fly comb 4 has an arm 5 whose one end is pivotally supported.
An arcuate comb portion 6 is provided at the other end of the. The pivot is provided by a rotary shaft 25 provided on the apparatus, and the entire fly comb 4 is swung in the direction of arrow G. The comb portion 6 is provided with a number of comb portions 6a inclined, and the inclination direction thereof is the same as the direction of the claw 2. The curvature of the comb portion 6 is set to be substantially equal to the circle centered on the rotation shaft 25. The distance between the three surfaces of the endless track and the comb 6 is set to 30 mm.

A protective plate 7 is provided between the tip of the comb portion 6 and the arm 5 for preventing the cotton-like material 1 from riding up. The width of this protective plate 7 is equal to the width of the fly comb 4,
It is designed to cover the whole. A baffle plate 8 is provided upstream of the endless track 3 with respect to the fly comb 4, that is, below the fly comb 4. This baffle plate 8 is arranged at a position where its lower end is 200 mm from the surface of the endless track 3, and its angle is substantially perpendicular to the plane of the endless track 3. The width of the baffle plate 8 is set wider than that of the fly comb 4, and the height H thereof is 300 mm.
