Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to an automatic traveling spreader used for automatically opening stacked raw material fibers in a spinning process.

BACKGROUND ART Recently, the raw material fibers deposited along the running path of a self-propelled main body are moved by a pair or one fibers installed in a lifting head on the side of the main body in parallel with the width direction of the raw material fibers. The fibers are opened while being peeled off into a thin film using a rotating cutter, which is sucked into a suction nozzle located directly above the rotating cutter so as to have an elongated opening in the width direction of the raw material fiber, and then transferred to the next process via an air intake duct. Automatic traveling type spreaders have been developed and are being put into practical use.

Problems to be solved by the invention The automatic traveling fiber opening machine of the above type is capable of separating the raw material fibers by the relationship between the amount of air sucked in from the opening of the suction nozzle and the amount of raw material fibers peeled off by the rotating cutter. There was a problem that the liquid would fall (spill) from the side of the suction nozzle.

This is because when the lifting head descends, the lower opening of the head is blocked by the deposited layer of raw material fibers.
This is thought to be because the amount of inflowing air is insufficient and the amount of peeling is too large. In addition, when the amount of air flowing into the head is insufficient, the pressure inside the head is reduced, and the surrounding atmospheric pressure presses the head onto the piled layer of raw material fibers, reducing the amount of raw material fibers peeled off by the rotating cutter. When this happens, more and more raw fibers may fall from the side of the suction nozzle, and large stubble may clog the intake duct.

Means for Solving the Problems In order to solve the above-mentioned problems of the prior art, this invention provides an air intake port of an appropriate size on the front surface of the tip of the elevating head to allow sufficient air to flow in. This is what I did.

The size of the air intake port above depends on the type of raw fiber,
The depth of cut of the rotary cutter, that is, the amount of production can be adjusted.

Function: According to this invention, sufficient air can flow in from the air intake port opened at the front end of the lifting head, so there is no shortage of air volume, and regardless of the size of peeling or the type of raw material fiber, it is possible to Stable production and operation are possible with no fiber spillage or clogging.

Embodiment FIGS. 1 to 3 show an enlarged perspective view of essential parts, a side view, and a front view of the automatic traveling fiber opening machine according to the present invention, in which 1 is a main body, 2 is an elevating head, and 3 is a rotating cutter. , 4 is a suction nozzle, 5 is an intake duct, 6 is an air intake port, 7 is a raw material fiber, 8 is a telescopic duct, and 9 is a fixed duct.

The main body 1 is configured to be movable along a guide rail 10 on the floor, and has a built-in self-propelled mechanism (not shown).
The raw material fibers 7 are sequentially transferred along the deposited layer under computer control.

The raw material fibers 7 include fibers of the same type or different types that are deposited along one or both sides of the running path of the main body 1.

The lifting head 2 is provided on one side or both sides of the main body 1 so as to be able to rise and fall via a lifting mechanism (not shown), and is automatically raised and lowered according to the piled height of each raw material fiber 7 as the main body 1 travels. automatically controlled by a computer.

The rotary cutter 3 is installed in the elevating head 2 so as to be rotatable in opposite directions via a drive mechanism (not shown), and has a large number of small protruding blades arranged in a staggered manner on its circumferential surface. The length spans the entire length in the width direction.

The suction nozzle 4 is fixedly installed in the elevating head 2 and is configured to move up and down with the elevating head 2 relative to the main body 1. It is left open all the way. The suction nozzle 4 has a U-shape that is open at the bottom, and is inclined so that the intake passage becomes narrower from the base to the tip, and a plurality of intake distribution plates 4a are provided along the intake passage to distribute the intake air. The plate 4a connects the intake passage to the raw material fiber 7.
The fibers are divided almost equally in the width direction, so that the intake air acts almost evenly in the width direction of the raw material fibers.

The base of the suction nozzle 4 is connected to an intake duct 5, and the intake duct 5 is connected to the upper end of the telescopic duct 8.

The lower end of the telescopic duct 8 is supported by the main body 1,
It is designed to expand and contract in a telescopic manner as the elevating head 2 moves up and down.

The lower end of the telescopic duct 8 is slidably engaged and connected to a fixed duct 9 fixed on the floor along the running direction of the main body 1.

The fixed duct 9 has a groove shape with an upper opening, and as shown in FIG.
a constitutes a movable weir plate that is slidably engaged in the groove and closes one of the grooves, and a bellows type cover 9 is provided between the other end of the fixed duct 9 and the lower end of the telescopic duct 8.
a is provided to close the upper opening of the fixed duct 9. The other end of this fixed duct 9 is
It is connected to the next step via a duct, and an intake blower (not shown) is provided in the middle of the duct to apply intake air.

An air intake port 6 is opened at the front end of the lifting head 2, and the size of the air intake port 6 can be adjusted depending on the type of raw material fiber and the cutting depth of the rotary cutter. For example, the air intake port 6 may be formed to have the maximum opening area and may be adjusted by attaching a cover, or a shutter may be provided.

The main body 1 moves along the deposited raw material fibers 7, the lifting head 2 is lowered onto the upper surface of the raw material fibers 7, and a pair of rotating cutters 3, 3 separates the upper surface of the raw material fibers 7 into a thin film and opens it. It is threaded, sucked through the suction nozzle 4, and sent to the next process. Suction by the suction nozzle 4 is achieved by allowing sufficient air to flow in from the air intake port provided at the front of the tip of the lifting head 2, which prevents fibers from falling from the side of the suction nozzle 4 and prevents clogging of the duct. can.
Incidentally, only one rotary cutter 3 may be used.

Effects of the invention According to this invention, sufficient air can flow in from the air intake port opened at the front of the tip of the lifting head, and there is no shortage of air volume, regardless of the size or type of peeling of raw fibers. Stable production and operation are possible with no spillage of raw fiber or clogging.
