Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cotton feeding device which can meet the demands for small lots of many kinds in a spinning factory.

[0002]

2. Description of the Related Art A conventional cotton feeding apparatus is constructed so as to meet the demand for a large number of small lots of a small variety, and scrapes a plurality of large amounts of raw cotton. Therefore, since the corresponding cards are also connected to a large number of units, it is not possible to supply a small lot of raw cotton, and it is only possible to make a changeover setup after the amount is collected, so it is not possible to quickly respond. In each process of blending and bottling, there is no mechanical equipment for truly small lots of raw cotton, and the models that can handle medium lots are mainly those that shorten and downsize the conventional blending machine.
Further, the cotton feeding system which is currently the mainstream of the card feeding device is a mass production system, and if it is adapted to a small lot as it is, the equipment cost becomes high, and the space becomes large and wasteful.

On the other hand, the above-mentioned mixing / blatting process is a process of holding a large amount of work-in-progress, and the machine becomes large-sized and heavy equipment, and it is easy to cope with mass production, but it is suitable for small-lot production. Was a difficult process. Moreover, since the mechanical elements such as lattices, beaters, and needles are frequently used for moving and defibrating cotton in the blending and beating process, cleaning must be performed when changing lots, and this cleaning requires a great deal of labor. I was there. Therefore, when small-lot production is performed with the current equipment, not only it takes a long time to obtain a card sliver, but also a lot of labor and time are required for cleaning at the time of lot switching before and after production. .

In FIG. 1, 5 is a cotton blower attached to the tip side of a cotton feeding duct 4 connected to the tip of the horizontal fixed duct 3, 6 is a reserve tank for storing cotton, and this tank 6 is A rotating cotton-feeding nozzle 61 connected to the discharge side of the cotton-blowing blower 5 is installed inside the upper part, and the rotation of the nozzle 61 stores the cotton sent from the cotton-feeding duct 4 by the action of the blower 5. The inside of this tank 6 is
The tank chambers 6a and 6b are divided into two parts except the lower part, and a plurality of air vent holes 62 with a wire mesh are provided substantially uniformly in each of the tank chambers 6a and 6b so that the inside of the tank 6 is uniformly supplied. In addition to making cotton possible, pressurizing the blower 5 to supply cotton and bleeding air from the hole 62 are repeated to store cotton with stable cotton density in the lower tank chamber 6c of the tank 6 and store it in the next card C. Is configured to be supplied.

Here, the above-mentioned cotton-blowing blower 5 acts to suppress the weight fluctuation of the spinning sliver by sucking and transporting the cotton and at the same time using the exhaust pressure to balance the cotton density. Also, the rotary cotton feeding nozzle 61 connected to the outlet of the blower 5 supplies cotton evenly into the tank 6 by its rotation and alternates the pressurizing action by the exhaust pressure to the two tank chambers 6a and 6b. The effect of suppressing the weight fluctuation of the spun sliver is enhanced by the synergistic effect of exerting the pressurizing effect on the cotton stored in the tank by exerting the above effect.

The above-mentioned reserve tank 6 is formed so as to have three stages of functions, from the upstream side of the tank 6 in this order, from the upstream side of the tank 6 to a distribution section, a split air vent section, and a merging / pressurizing section. That is, since the distribution unit supports the cotton blower 5 and the rotating cotton feeding nozzle 61 and includes them,
Air and cotton can be discharged into the tank 6 while swirling, and cotton is evenly distributed to the divided tank chambers 6a and 6b located in the second stage, and intermittent pressurization is performed. Two
The tank chambers 6a and 6b divided into two at the stage are fed by half the rotation of the cotton feeding nozzle 61 that rotates with respect to the tank chambers 6a and 6b, which are independently formed and have the same shape, Therefore, the cotton from the nozzle 61 is intermittently and alternately supplied. Then, at the time of cotton feeding, the cotton is pushed down by the air pressure and at the same time, the air is discharged from the air vent hole 62 to the outside of the tank, and when the rotating cotton feeding nozzle 61 makes a half rotation on one tank chamber 6a or 6b side, the one Since the tank room of the other has no cotton feeding and pressurizing action, the other tank room 6b
Or, cotton feeding and pressure action start on the side of 6a.

The tank chamber 6 divided into two as described above
The cotton stored in each of a and 6b enters one tank chamber 6c set in the lower stage of the tank 6 and merges, and the next card C
However, regardless of the supply of cotton, the cotton blower 5 and the rotary cotton feeding nozzle 61 are operated and continue to act on the cotton in the tank 6 during the operation of the card C. Therefore, the amount of cotton in the tank 6 is always detected, and when the allowable lower limit is reached, the cotton feeding is requested, and when the upper limit is reached, the cotton feeding is stopped, the operation of the cotton scraping unit U, the duct 1, If the movement of 2 in the X, Y and Z directions and the operation of the blower 5 are sequentially controlled, the cotton amount can be reduced while suppressing the weight change only by the configuration of the cotton blower 5, the rotary cotton feeding nozzle 61 and the reserve tank 6. You can control.

Numeral 7 is a raw cotton which is placed on the pallet 8 and is scraped off. As shown in FIG. 1, the raw cotton 7 has a next lot of raw cotton 7'on the pallet 8 '. It is better to prepare in advance, and by doing so, it is possible to smoothly switch lots of raw cotton.

The cotton feeding apparatus according to the present invention is constructed as described above. Next, its operation will be described. First, as shown in the drawing, the raw cotton 7 is arranged under the horizontal movement duct 1, and the cotton scraping unit U is positioned at one side of the front portion of the raw cotton 7 (the tip side of the horizontal movement duct 1). 1
2, 13 and the cotton blower 5 are driven to operate the cotton scraping unit U of the horizontal transfer duct 1. At this time, when the two motors 12 and 13 (rotational speed 12> 13) are driven, the rotation of the chains 18 and 18 'causes the roller drive shaft 19 to be cut off as shown in FIG. Rotate and rotate the pair of scraping rollers U1 and U2 in the direction of the arrow in FIG. 4 to scrape the raw cotton 7 and the inside of the horizontal movement duct 1 (cotton path).
It moves to the right in the Y direction together with the seal belt 2A while taking in. In this way, when the cotton scraping unit U reaches the right end of the horizontal moving duct 1 in the Y direction, the motors 12, 13
The number of revolutions is reversed (the number of revolutions is 12 <13) to move the scraping unit U to the left side in the Y direction. Vertical duct 2 at the same time
The traveling unit S is operated to move the vertical duct 2 in the X direction (left side in FIG. 1) by a predetermined amount. As a result, the cotton scraping unit U moves along with the horizontal moving duct 1 in the X direction (left side in FIG. 1) guided by the vertical duct 2 by the amount of scraped cotton by the above operation. Since the scraping unit U moves in the X and Y directions at the same time, the scraping unit U runs diagonally on the upper surface of the raw cotton 7. Further, since a part of the scraping unit U (guide roller) is always on the raw cotton, the collapse of the raw cotton angle before and after the reversal is prevented.

The above-mentioned scraping work is repeatedly performed on the raw cotton 7 in a zigzag manner, and when the first entire surface scraping work on the raw cotton 7 is completed, the lifting motor 27 is driven to move the horizontal moving duct 1 to the vertical duct 2. Along with, the scraping thickness of the previous time is lowered to scrape the next upper surface of the raw cotton 7. The cotton that is scraped off one after another in this way
By the suction force of the cotton blower 5, the cotton moves inside the horizontal moving duct 1, the vertical duct 2, and the horizontal fixed duct 3,
It is sent to the cotton feeding duct 4 and is stored in the reserve tank 6 from the rotary cotton feeding nozzle 61.

When all the raw cotton 7 is scraped off and the work is finished as described above, the two scraping rollers U1 and U2 are removed.
By the guide rollers U3 and U4 attached to the front and rear of the
Since the scraping rollers U1 and U2 are supported on the pallet 8 in a slightly floating state, the raw cotton 7 on the pallet 8 is hardly left behind and is entirely stored in the reserve tank 6 and supplied to the card C. is there. As mentioned above,
If another pallet 8'on which the required raw cotton 7'is placed beside the pallet 8, it is possible to cope with the lot changeover very easily.

In the above example, the scraped cotton is fed to the reserve tank 6 and fed to the high speed card C from the reserve tank 6, but from the cotton feeding device of the present invention to a plurality of reserve tanks. You may make it correspond to a several low speed card by switching and sending. FIG. 5 shows an example thereof, in which one cotton feeding device and a plurality of reserve tanks 6 are connected by connecting a multi-branching type cotton feeding duct 4 with a switching damper D interposed as appropriate.

[0027]

The present invention is as described above, and the cotton scraping unit is attached to the lower surface so that the cotton scraping unit can run in the longitudinal direction, and the horizontal moving duct having a cotton path inside is used in the running direction of the cotton scraping unit. A vertical duct that is movable in the horizontal direction orthogonal to the inside and is vertically movably mounted in a vertical duct that has a cotton passage formed inside, and connects the cotton paths to each other, and the upper end of the vertical duct is In order to feed the cotton to a desired location on the tip side of the horizontal fixed duct, the two cotton paths are slidably supported in parallel with the moving direction by a horizontal fixed duct formed internally in the cotton path. A cotton feeding duct which is connected to a cotton feeding duct equipped with a cotton blower, and which is made of cotton scraped by the scraping unit,
By the suction force of the cotton blower, it is sent to the cotton path of the vertical duct through the cotton path of the horizontal moving duct, and is fed from the cotton feeding duct to the required location via the cotton path of the horizontal fixed duct. Since this is a feature, it can quickly meet the demands for small lots and a wide variety of products, and build a production system directly connected to the card.

Further, since the cotton feeding device has a simple structure,
The occupied area is small, the space with raw cotton set is the same as the card, and if you secure a supply path for raw cotton,
It can be installed adjacent to the card, and one cotton feeding device can handle from one card to multiple cards.

It is possible to switch between lots simply by preparing the raw cotton of the next lot in the spare raw cotton space and changing the operating range of the scraping unit so that the raw cotton of the next lot can be accessed. Since the raw cotton of the bales can be scraped without breaking the shape of the raw cotton, it is possible to easily switch the raw cotton of less than one bale.

Further, because of the above-mentioned configuration, the number of areas requiring cleaning is reduced as a whole, swift lot switching is possible, and the weight of the apparatus itself is reduced, so maintenance is easy.
