Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a fiber control tower feeder for feeding hair to a carding machine or a felting machine in a spinning or nonwoven fabric manufacturing process.

[0002]

[Prior art]

 Conventionally, in this type of manufacturing process, the hair is automatically fed to the carding machine, but there is a self-regulating hair feeder shown in FIG. 6, for example. This self-regulating hair feeder 100 is provided with an inclined lattice 103 in which numerous spikes 102 are planted on one side in a hopper 101, and a scraping comb 104 is provided outside the upper end portion thereof. A weighing box 105 is arranged below the scraping comb 104. Therefore, when the raw material is thrown into the hopper 101, the raw material is carried to the upper portion by the inclined lattice 103, and the excess raw material is scraped off by the stripper 106 during that time. Then, the raw material carried to the upper portion of the inclined lattice 103 is scraped off by the scraping comb 104 into the weighing box 105, and when the amount becomes a certain amount, the movement of the inclined lattice 103 stops and at the same time the lower portion of the weighing box 105 opens. The raw material in the weighing box 105 falls on the upper surface of the supply lattice 107. When the supply is completed in this way, the inclined lattice 103 rotates again and the same operation is repeated.

[0003]

[Problems to be solved by the device]

 However, in the conventional fiber control tower feeder 100, since the slanted lattice 103 having a predetermined length is installed, the equipment becomes large and the equipment cost increases, and moreover, the raw material is fed to the weighing box 105 in a fixed amount. The productivity is low because it is a so-called batch process in which the raw material in the weighing box 105 is dropped onto the upper surface of the supply lattice 107 after the movement of the inclined lattice 103 is stopped. Furthermore, it is difficult to remove the raw material that has invaded the countless spikes 102 and the scraping combs 104 of the inclined lattice 103, and it takes a lot of time and labor to clean the raw material. There were various problems that it took time. Therefore, the present invention has been made to solve the problems seen in the prior art.The equipment cost is low, the productivity is improved, and the cleaning is easy, so that lot switching does not take time. The purpose is to provide a fiber control tower feeder.

[0004]

[Means for Solving the Problems]

 In order to achieve such an object, a fiber control tower feeder according to the present invention is a hollow cylinder for feeding hair to a carding machine or a felting machine on a shooter moving table connected to the carding machine or the felting machine. The body-shaped tower is erected, the feed port of the raw material feed pipe for pneumatic feeding of raw material is provided downward at the upper end of the tower, and the air exhaust port for discharging only air to the outside at the lower end and the car. And a lower end discharge port connected to a sewing machine or a felting machine, and upper ends are axially supported on both sides of the supply port in the tower and reciprocally oscillated by appropriate driving means and discharged together with compressed air from the supply port. A pair of raw material distribution vanes are installed to distribute and drop the raw material to be distributed evenly downward, and the raw materials deposited in the tower are carded in sequence. Gumashin or to felting machine was set to continuous feeding. As described above, since the material distribution blades are only arranged in the tower, the structure is simple and the hair can be continuously fed to the carding machine or the felting machine without interruption, thus improving the productivity. . Further, since the raw material distribution blade is formed in a comb-like shape, the raw material is easily dropped and cleaning is easy. Therefore, this makes it possible to switch the lot of raw materials without spending a lot of time.

A weigher 5 is installed inside the shooter moving table 1 so as to face a lower end discharge port 8a of a tower 8 which will be described later, and raw materials weighed by the weigher 5 are fed to a carding machine 7 by a belt conveyor 6. . The weighing device 5 may not be provided.

Reference numeral 8 denotes a stainless steel tower having a hollow cylindrical shape, which is erected vertically on the upper surface of the shooter moving table 1. The supply port 9a of the raw material supply pipe 9 is connected downward to the upper end of the tower 8 so that the raw material (for example, synthetic fiber) can be fed under pressure from the raw material supply pipe 9 into the tower 8 by using air pressure. It has become.

The towers 10 and 10 are reciprocally swingably arranged on both sides of the supply port 9a in the tower 8, and the raw materials discharged together with air from the supply port 9a are evenly distributed downward in the tower 8. It is a pair of material distribution blades for dropping. As shown in FIG. 3, each of the raw material distribution blades 10, 10 has a comb-teeth shape extending downward, and each upper end thereof is supported by the support shafts 11, 11. The support shafts 11 and 11 are horizontally and horizontally arranged at predetermined intervals, and both ends thereof are axially supported by bearings 13 and 13 on opposite side walls 12 and 12 of the tower 8. Further, link members 14a and 14b are fixed to one ends of the support shafts 11 and 11, and the link members 14a and 14b are pivotally connected by a connecting rod 15. Further, a vertically long slot 16 is provided below the one link member 14a.

Reference numeral 17 denotes a reduction motor as a drive source for oscillating the raw material distribution blades 10 and 10. The drive shaft 18 is connected to the base end of a crank 19 and the tip of the crank 19 is connected to the link member. It is loosely fitted in the long hole 16 provided in 14a. The deceleration motor 17 drives the crank 19 to rotate, which causes the link members 14a and 14b to oscillate reciprocally, and at the same time, the pair of raw material distribution blades 10 and 10 are moved in a range shown by a solid line and a chain line in FIGS. And swing back and forth in the same direction.

A plurality of viewing windows 20, 20, ... Are provided at a predetermined height position on the side wall 12 of the tower 8. Further, an air deaeration side plate 21 formed of a mesh or a punching plate is provided on the side surface of the tower 8 below the observation windows 20, 20, ...

An air outlet 23 for discharging the air in the tower 8 is provided on the side surface below the air deaeration side plate 21. As shown in FIG. 5, at the air outlet 23, support shafts 25, 25 are installed between the opposite side walls 24, 24 of the tower 8. The support shafts 25, 25 have a hairpin having a cross-sectional shape through a collar 26. Innumerable slider plates 27 that are bent and formed into a shape are supported in a skewered shape with a slight gap. Since the inner end of each slider plate 27 is bent like a hairpin, the fibers as the raw material fall without being entangled, and only air is discharged to the outside from the gap between the slider plates 27, 27.

The fiber control tower feeder of the present invention has the above-mentioned configuration, and the raw material supplied from the raw material supply pipe 9 through the supply port 9a into the tower 8 together with the compressed air is the raw material distribution blades 10 and 10 that reciprocally swing. Are evenly distributed and fall in the tower 8. At this time, since both raw material distribution blades 10 and 10 are formed in a comb shape extending downward, the raw material flows down along the comb teeth, and the air passes between the comb teeth. Since it is not blown away by, the uniform distribution of raw materials can be performed well.

Then, the falling raw material is accumulated almost uniformly on the lower end side in the tower 8 while its own weight and air pressure are applied, and the material is sequentially and continuously discharged from the lower end discharge port 8a. On the other hand, the compressed air is discharged from the air outlet 23. At this time, the state of the raw material accumulated in the tower 8 can be visually confirmed from the outside through the respective observation windows 20, 20, .... In addition, the amount of deposition with respect to the amount of raw material discharged from the lower end discharge port 8a is determined, and when the raw material is deposited more than necessary, it is detected by the pressure sensor 22 and the supply from the raw material supply pipe 9 into the tower 8 is controlled. It is supposed to be done.

The raw material discharged from the discharge port 8 a is weighed by the weighing device 5, conveyed by the belt conveyor 6 and supplied to the carding machine 7. The belt conveyor 6 does not necessarily have to be installed, but may be installed in the shooter moving base 1 as shown in FIG. 1 if necessary. A felting machine is used in place of the carding machine 7 in the process of producing the nonwoven fabric.
