Description

[Detailed description of the invention] This invention relates to a straw grass arranging device that separates and arranges the tangles of straw grass stems and culms to be loaded into a tatami mat knitting machine, and applies an appropriate amount of moisture to them. .

The rush that has been cut at a certain height above the ground is passed through a rush sorting device, and short culms and stalks that do not reach a certain length are picked out, sorted into long and short ones, and then dyed with natural soil or treated. Processes such as soaking and drying are carried out,
It is finished as a material for tatami mats.

In order to load the thus-treated strawberry stalks into a tatami surface knitting machine, the bundle of strawberry stalks is passed onto a conveyor, which conventionally has two ropes that run endlessly in parallel. The conveyor is conveyed in a direction perpendicular to the culm, and the overlaps are conveyed as parallel to each other as possible while removing tangles, and at the end of the conveyor, to give it flexibility and to avoid discoloration, the entire length from the back, that is, from the tip of the stem culm. The lining work of applying mist to keep about 20% of the material wet, applying an appropriate amount of moisture, aligning the root end surfaces, and tying them into a fixed bundle usually requires two people, or three people if the feeding speed is to be increased. It is carried out by applying

23' is a stopper attached to the lower end of the operating rod 23.

A pair of guide plates 33 are provided close to the separation plate 20 and have an arcuate guide groove centered on the rotation axis of the hinge 21.

The separation plate 20 is fixed at its lower end, and its movement is restricted by a guide pin that is slidably engaged with the guide groove.

The power transmission system will be described with reference to FIG. 4, which schematically shows the power transmission system of this device.

34 is a motor, 35 is a worm reducer, both of which are mounted on plywood fixed to the base 5, 36 is an intermediate shaft,
It is rotatably supported on the substrate 5 via a bearing.

The rotation of the motor 34 is transmitted to the worm reducer 35 via the V belt 37, decelerated thereby, and further reduced by the V belt 37.
It is transmitted to the intermediate shaft 36 via the belt 38, and rotates it at, for example, 250 rpm.

A conveyor drive shaft 39 is rotatably supported by the base 5 via a bearing.

The rotation of the intermediate shaft 36 is, for example, doubled in speed through a pulley 40 fixed to the shaft end thereof, a V pulley 41 fixed to the shaft end of the conveyor drive shaft 39, and a V belt 42. 39 to rotationally drive an eccentric disk 42 fixed to the other shaft end.

Reference numeral 43 denotes a connecting rod, which is connected to the eccentric pin of the eccentric disk 42 and the lower end of the swing lever 44 by pins, respectively.

The swinging lever 44 is swingably supported on the base 5 at its intermediate portion, and has an upper end that is elongated in the vertical direction and is connected to the swinging base plate 6 on its lower surface. It is connected via a pin.

Therefore, the conveyor drive shaft 39 is, for example, 500 rpm.
When rotated by the eccentric disk 42, the swinging base plate 6 is configured to swing in the front and back direction indicated by the arrow 500 times per minute, for example, about 4077E+71 via the connecting rod 43 and the swinging lever 44. becomes.

Reference numeral 45 denotes a separation plate drive shaft, which is rotatably supported on the base 5 below the intermediate shaft 36, and the rotation of the intermediate shaft 36 is reversed through gears 46 and 46' having the same number of teeth that mesh with each other. It is arranged to be transmitted in the direction.

Note that the baffle plate 19' suspended above the separation plate 20
A reflecting plate 47 having the same width as the separating plate 20 is attached to the separating plate 20 .

Next, the operation of this device will be explained.

For example, long strawberry stalks are stacked and fed into the feeding section 1 with their bases in contact with the guard 3, and when the motor 34 is driven to rotate, the swinging conveyor rods 2, 2'
performs a rocking motion, for example, 500 times per minute in the front-rear direction indicated by the arrow.

When the partition rod 4 is removed in this state, the strawberry stalks stacked in the input section 1 are transferred to the swinging conveyor rod 2゜2'.
The conveyor rods 2, 2' are moved in the direction of the arrow by the swinging motion of the conveyor rods, but when the conveyor rods 2, 2' move forward and stop, the stepped portions approach the baffle plate 19, so that the baffle plate 19 Acting as a weir, the laminated stem culms collapse forward and pass through the gap between the baffle plate 19 and the conveyor rod 2.2' without being sent out all at once, and the amount of delivery is regulated, gently tilting in the forward direction. It is delivered by the inertia imparted by the forward movement of the conveyor rods 2, 2'.

Since the conveyor rod 2.degree. 2' is also inclined toward the guard 3 side, the strawberry stalks are sent out with their bases touching or coming close to the guard 3.

On the other hand, since the separation plate drive shaft 45 is configured to rotate in the direction of the arrow as described above, each rotation of the eccentric disk 28 causes the eccentric pin 29 to move the actuating piece 27 against the elastic force of the coil spring 30. When the pin 29 is removed from the actuating piece 27, the actuating rod 23 is pushed downward by the spring of the coil spring 30 compressed between the collars 31 and 32 by the downward movement. It is raised all at once by force.

When the stopper 23' collides with the support arm 26, the operating rod 23 is suddenly stopped.

Therefore, the separator plate 20 is rapidly raised between the conveyor rods 2 by the movement of the actuating shaft 23 that is repeated for each rotation of the drive shaft 45, and at the time of a sudden stop, the inertia imparted thereto causes the separator plate 20 to move upwardly from the hinge 21. The guide pin at the lower end of the separation plate 20 moves into the guide groove of the guide plate 33 as shown by the two-dot chain line in FIG. It springs up until it comes into contact with the upper edge of the frame and stops, and then returns to the state shown in the figure by its own weight.

That is, the separating plate 20 performs the above-mentioned operation at a rate of, for example, 25 minutes per minute.
(2) The swinging motion of the conveyor rod 2 is intermittently repeated every two times.

Since the above-described movement of the separating plate 20 is carried out when the strawberry stem culms are delivered onto the conveyor rod 2 directly above the separating plate 20 with a considerably reduced bottom layer, the baffle plate 19' is already removed. Most of the stratified stem culms passing through are thrown away by the separation plate 20 in the delivery direction, separated while being untangled, and placed on the conveyor rod 2 again.

Then, the stratified stem culm in front of the baffle plate 19' is also thrown away, untangled, collided with the reflection plate 47 above, and returned onto the conveyor rod 2.

In this case, the portion of the separating plate 20 to which the guide pin is attached is deformed at the point where it is bent downward and is made approximately perpendicular to the conveyor rod 2. The effect of this will be temporarily suspended.

In this way, the water tray 11 passes through the last baffle plate 19.
Conveyor rod 2 and fixed guide 12 suspended above
．． The straw stems sent out to 12' are completely untangled, the distance between them is widened, and they pass over the water receiver 11 while maintaining a parallel state.

During this time, an appropriate amount of water from the water supply pipe 18 and compressed air from the compressed air introduction pipe 17 are atomized by the nozzle 16 and then sprayed to uniformly apply an appropriate amount of moisture to the straw stems.

In this case, the mounting angle of the nozzle 16 is adjusted so that about 20% of the total length of the stem culm does not get wet from its tip.

This is done in order to provide appropriate moisture to the thick part from the base of the strawberry stem culm to make it supple, and to prevent water from splashing on the thin part at the supple tip to avoid discoloration. be.

The straw stalks treated in this way are sequentially dropped into the storage section 13, and when a certain amount is accumulated, they are manually tied together, taken out, and loaded into a tatami face knitting machine.

Since the volume of the input section 1 is sufficiently larger than that of the storage section 13, the bundling work can be easily performed while the operation continues.

In this embodiment, the conveyor rods 2, 2' constituting the shaking conveyor are made of round rods, but they may also be made of strips.

It goes without saying that the same process as in the case of the long ones described above can be carried out on short pieces of strawberry stems with a length of about 1 m.

As is clear from the above explanation, with the straw grass arranging device according to this invention, the arranging work, which was conventionally performed manually by two to three skilled workers, can be done by one worker with almost no skill. It is possible to do this with high efficiency.

In other words, by the forward motion given to the strawberry stem culms by the swinging conveyor, which has a gentle slope in two directions and also has a step-like section, and the feed amount regulating action of the baffle plate as a dam,
The straw stem culms that are stacked and fed in are aligned with their root ends, and the bottom layer is thinned out before being sent out.Then, by the intermittent flipping motion of the separating plate, it is thrown away in the sending direction, which helps to remove tangles. They can be separated together.

Since the distance between them is widened and the water receivers are made to pass above each other while maintaining a parallel state, it is possible to uniformly apply an appropriate amount of water to the necessary locations.
