That is, there is used a device in which two or more sets of bale breakers and scales are arranged in parallel, a transfer conveyor is provided at the outlet of the scales orthogonal to the bale breakers and scales, and an opening machine is provided at the tip of the transfer conveyor. ing. In this apparatus, the raw material fibers that have passed through the bale breakers and the weighing device are each tufted on the transfer conveyor, placed in parallel with the width direction of the conveyor, and supplied to the fiber opening machine in this state.

Therefore, when the fibers are unraveled by the opening machine,
The fibers are not yet mixed, but will be mixed when the fibers are delivered using an air stream. For this reason, the mixing is not sufficiently uniform, and when a futon is produced, for example, the distribution of fibers varies depending on the part.

[0004]

Therefore, the present invention was devised for the purpose of obtaining a fiber mixing method and apparatus capable of more uniform mixing.

[0005]

According to the method of the present invention, two or more kinds of raw material fibers are each opened into a tuft with a bale breaker, weighed with a weighing machine, and then spread into a sheet, and further, By laminating two or more kinds of fibers in this sheet shape,
After that, the fiber is opened by a fiber-opening machine, delivered, and the fibers are mixed by the opening and delivering, which is a fiber mixing method.

The device of the present invention comprises two or more kinds of raw fibers,
Each of which is opened in a tuft form, the bale breaker and the measuring device for measuring are installed in parallel, can be rotated around a vertical axis, and while receiving the fiber that has passed through the measuring device,

The bottom conveyor 16 is a lattice conveyor, receives the bale of the raw material fiber from the bale conveyor 15, and transfers it to the left in FIG. 2 while slightly lowering it. The spike conveyor 17 is a lattice conveyor having a large number of needles planted on its surface, and the bottom conveyor 16
The veil of the raw material fiber at the tip position is scratched to peel off the fiber, and the fiber is transported obliquely upward. At this time, the veil of the raw material fibers at the tip position of the bottom conveyor 16 is pressed against the spike conveyor 17 while sliding or rolling on the bottom conveyor 16. The Evener conveyor 18 is a lattice conveyor having a large number of needles planted on the surface thereof, is provided near the upper end of the spike conveyor 17, and scrapes off excess fibers adhering to the spike conveyor 17 to make a uniform state. . The clear roller 19 is composed of a roller having a large number of needles planted on its surface, is provided in the vicinity of the other end of the EVENER conveyer 18, scrapes the fibers adhering to the EVENER conveyer 18, and drops them on the bottom conveyer 16. Let The stripper roller 20 is composed of a roller having a large number of needles planted on the surface thereof, is provided near the upper end of the spike conveyor 17 in the vicinity of the tip side surface thereof, and scrapes fibers adhering to the spike conveyor 17.

Since the bail breaker 11 has the above-mentioned structure, the veil of the raw material fibers is opened, and the fibers are made into tufts and dropped.

In the measuring device 12, the upper shutter 21 is
Close to stop the fibers falling from the stripper roller 20,
The fibers can be opened and dropped. Wepan 22

Since the weighing device 12 is constructed as described above, the lower shutter 23 is closed, the upper shutter 21 is opened, the fibers are stored in the wepan 22, and when the weight reaches a preset value, the upper shutter 21 is closed and the lower shutter 21 is opened. Open the shutter 23,
The fibers are drawn out by the delivery rollers 24, .... In this way, a metered amount of fiber is delivered.

The turntable conveyors 25 and 26 are lattice conveyors, respectively, which can rotate 90 degrees about the vertical shafts 27 and 28, and are provided at the lower portions of the weighing devices 12 and 14 and the tips of the bale breakers 11 and 13. ing.
The turntable conveyors 25 and 26 are used for the weighing machine 1.
When the fibers are delivered from the fibers 2 and 14, while receiving the fibers, the fibers are horizontally transferred in the same direction as the bale breakers 11 and 13 to spread the fibers into a sheet.

The laminating conveyor 29 is formed by connecting three lattice conveyors 29a, 29b, 29c, and the lower parts of the turntable conveyors 25, 26 are connected to the bale breaker 11,
The vehicle runs in a direction orthogonal to 13, that is, to the right in FIGS. Therefore, the turntable conveyor 2
When 5 and 26 rotate 90 degrees counterclockwise and run, as shown in FIG. 4, the sheet fibers 30 and 31 on the turntable conveyors 25 and 26 are placed on the laminating conveyor 29 and laminated.

The opener 32 may be a known one and is connected to the laminating conveyor 29. This opener 32
Is mainly composed of a roller in which a large number of needles are planted on the surface, and the fibers are disentangled and sent to the next step together with the air flow by a blower.

Since the mixing device 10 has the above-described structure, when a veil of different raw material fibers is supplied to each of the bale breakers 11 and 13, the bale breakers 11 and 13 open the fibers, and the weighing devices 12 and 14 respectively. A predetermined weight is taken out, turned into sheets on the turntable conveyors 25 and 26, and stacked on the stacking conveyor 29. After that, it is opened by the opening machine 32,
At this time, the respective fibers are mixed and further blown out by a blower, at which time they are mixed again.

It should be noted that the delivery of the measuring instruments 12 and 14, the transfer of the turntable conveyors 25 and 26, the rotation, and the transfer of the stacking conveyor 29 are adjusted so as to be performed at appropriate timing so as to cause the above operation. There is no end.

In the above example, two kinds of fibers are mixed, but three or more kinds of fibers can be mixed by arranging three or more sets of bale breakers and scales side by side.

[0021]

As described above, in the fiber mixing method and apparatus of the present invention, raw material fibers are laminated in a sheet form and sent to an opening machine, so that the fibers are uniformly mixed.
