Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for producing straw in a tatami-making device that can automatically produce homogeneous tatami while maintaining a uniform supply of straw in the containers described above. This invention relates to a metered supply device.

As a conventional tatami making device, for example, Fig. 2 (a) and (b)
There are some things shown below. This tatami making device consists of a belt line 1 that is stretched endlessly and is conveyed continuously or intermittently in the direction of the arrow, and a back material 2 that is placed on the belt line l and is conveyed in the same direction. A uniform supply step in which straw 3 (hereinafter referred to as the lower layer 3) is supplied and placed on the lower layer 3 (consisting of insect repellent paper) in a direction parallel to the conveyance direction, and cut straw 4 is evenly spread on the lower layer 3. a cut straw scattering step, a large arrangement supply step of supplying and placing straw 5 (hereinafter referred to as large arrangement 5) on the cut straw 4 in a direction perpendicular to the transport direction; The process includes the above process of supplying and placing the straw 6 (hereinafter referred to as 6 above) in a direction parallel to the tatami mat, and the sewing process of forming the tatami main body by sewing the layers stacked in this way with a sewing machine.Finally, the tatami surface is 7 completes the final product. The base material supply process includes a base material supply machine 10, which supplies and places a predetermined amount of the base material 3 on the back material 2. The cut straw spreading process is carried out using the cut straw spreader 11.
In order to make the surface of the lower part 3 flush, cut straw 4 on the lower part 3.
Diffuse a predetermined amount. The large arrangement supply process and the above-mentioned supply process each include a large arrangement supply machine 12 and the above-mentioned supply machine 13,
The main arrangement 5 and the above-mentioned 6 are sequentially supplied and laminated at a predetermined density (thickness). In the sewing process, a sewing machine 14 is provided, and the laminates laminated in each previous process are sewn into one piece.

However, with conventional tatami-making equipment, it is difficult to always discharge a uniform amount of straw from each feeding machine during each person's feeding process due to the fact that the diameter and shape of the straw itself is not uniform and there are performance issues with the feeding machine. Therefore, there was a problem in that the amount supplied by each person varied (a state in which thick parts and thin parts were mixed), resulting in variations in the quality of the final product. Therefore, as shown in FIG. A fulcrum 32 is provided at the center of the supporting member 31, and when the amount of straw 26 supplied from the feeder A to the measuring plate 30 exceeds the appropriate amount or falls below the appropriate amount, the straw is 2
Detection means 33 and 34 for detecting excess or deficiency in the supply amount of No. 6;
A first switch 35 is disposed above the other end of the support member 31 to activate the detection means 33 and stop the feeder A when the supply amount exceeds the appropriate supply amount. Feeder A that was activated and fell below the appropriate supply amount
A quantitative straw supplying apparatus has been proposed in which a second switch 36 for stopping all processes other than the above and driving of the belt line 1 is disposed below the other end of the support member 31.

However, when using the apparatus described in "-", only one end of the straw 19 discharged from the supply IA is unevenly placed on both the front end of the measuring plate 30 and the belt line l, resulting in a decrease in measuring accuracy, Measuring plate 30 - Straw blown away by Hi 1
Due to reasons such as instability due to the difference between the speed of belt line 9 and belt line 1, a satisfactory effect could not necessarily be obtained.

The present invention has been made in view of the above, and proposes a quantitative straw supply device for a tatami mat making machine that can always supply a fixed amount of straw in each person's supply process.

Hereinafter, the tatami-making device of the present invention will be explained in detail. For each process other than the quantitative feeding device, see Figure 2 (a).
(b) shall be cited.

FIG. 1 is a schematic diagram of the structure of the straw quantitative supply device in the tatami mat-making apparatus of the present invention. A straw support member 15a provided at a distance, and a straw supply 4
A first switch mechanism 18 that stops the driving of the feeder A that exceeds the appropriate supply amount when the amount of straw 16 supplied from 1 tA exceeds the appropriate amount, and a first switch mechanism 18 that stops the driving of the feeder A that exceeds the appropriate supply amount, and a second switch mechanism 19 for stopping all processes other than the feeder A and driving of the conveying means;

The switch mechanism 18.19 of No. 2 includes measuring tools 20.21 arranged front and back on the discharge port side of the supply gIA, and measuring rods 22.21 supporting each of these measuring tools 20.21 at one end.
23, a fulcrum 24.25 for supporting the central position of these measuring rods 22.23 and swinging both ends of the measuring rods 22.23 symmetrically in the vertical direction; and L-shaped measuring rods 22.23. 2
A first switch 26a provided at each end of the other end of 3
, 26b, and a second switch 27a provided below each
, 27b, the first switch mechanism 18 operates when the first switches 26a and 26b are turned on, and the second switch mechanism 19 operates the second switch,
It operates when the switches 27a and 27b are turned on. Note that the measuring rods 22 and 23 are provided with weights 28.

Therefore, the first switch mechanism 18 connects the two measuring instruments 2
The first switch is either 0 or 21.

If only the first switch 26a or 26b is switched on or off, it will not operate and the supply operation of the supply mA will not change. When both first switches 26a, 26b are switched on, the supply machine A of the process (e.g. Feeding machine 10 in Figure 2)
stops, and both first switches 26a, 26b
When the first switch mechanism 18 is switched off, the first switch mechanism 18 also stops operating. Similarly, in the case of the second switch mechanism 19, only when the inner second switches 27a, 27b are switched on, the supply I! Only when the entire line other than A (feeding machines 10, 12, 13, sewing machines 14, etc. related to all other processes including belt line 1 in Fig. 1) is stopped and both are switched off, The second switch mechanism 19 is also configured to stop its operation.

Next, one measuring tool 20 of the pair of measuring tools 20.21
is arranged in front of the straw support member 15a fixed to the lower side in the discharge direction of the discharge port of the feeder A, and the other measuring tool 21 is arranged further in front of the one measuring tool 20.

The straw 16 discharged from the feeder A is placed on the straw support member 15a, the front measuring tool 21, and the rear measuring tool 2o, and
Get on belt line 1. When the belt line moves, the straw 16 on the belt line L is dragged accordingly, and the straw handles 6 on the rear measuring tool 20 and the front measuring tool 21 entangled therewith are also pulled forward.

As long as the feeder A is continuously feeding the appropriate amount of straw 16 onto the measuring tool 20.21, the measuring rod 22.23 will not swing vertically, and the straw 16 will not move on the measuring tool 20.21. The straw 16 slides down and continuously descends onto the belt 1, but when an amount of straw 16 exceeding the appropriate amount is supplied, the measuring devices 20 and 21 at the rear and front portions descend under the weight of the straw 16 and move forward and backward. each measuring rod 2
2. The rear end portions 22a and 23a of 23 are raised and both first
switch 26a, 26b to turn it on.

When both the first switches 26a and 26b are switched on, the first switch mechanism 18 is actuated, the feeder A in the process stops feeding, and the straw 16 remaining on the measuring tool 20.21 is transferred to the belt. The measuring tool 20,21 gradually slides down and decreases, and as it approaches the proper amount, it gradually rises, and when it reaches the proper amount, it returns to its original position. Measuring tool 20.2
1, the rear end 22a of the measuring rod 22.23,
23a is lowered and both first switches 26a, 26b
is turned off (the amount of straw 16 on the measuring tool 20, 21 has decreased to the appropriate amount), the feeder A is started again, and the straw 1
Start supplying 6.

On the contrary, when the amount of straw 16 discharged from the feeder A decreases and falls below the appropriate amount, the front and rear measuring tools 20.21 rise, so that the rear ends 22a, 23a of the measuring rod 22.23 is lowered in synchronization with this, and both second switches 27a,
27b is switched on. second switch 27a,
27b causes all lines other than the supply process to stop driving. During this time, only the feeder A in the feeding process continues to drive and continues to discharge the straw 16, so the straw 16 fed onto both measuring tools 20 and 21 accumulates and increases.
When the accumulated amount reaches the appropriate amount, the weight of the straw 16 causes the rear end 22a to
, 23a rises. When the rear end portions 22a, 23a rise twice and both the front and rear second switches 27a, 27b are turned off, the drive stoppage of all other lines is released. While other processes are stopped, supply shortages in the relevant process can be resolved and uniform supply can be ensured. In this way, in response to fluctuations in the supply amount of a certain feeder A, the supply of straw 16 may be stopped, or
Since the drive of all other processes can be stopped, the amount of straw 16 that can be fed onto the belt 1 or on top of the straw 16 that has already been fed onto the belt 1 in the previous process is always uniform, and the straw 16 is not stacked. It becomes possible to maintain a uniform amount of each layer. The appropriate amount of straw 16 to be supplied is adjusted by changing the position of the weight 28.

As mentioned above, when 516 is supplied from the straw feeder A, the dye 16 on the rear measuring tool 20 is supported by the rear measuring tool 20 and the straw support member 15a at the front and rear parts, and the front measuring tool 20 and the straw supporting member 15a The straw 16 on the tool 21 is supported by the belt line 1 and the rear measuring tool 20 at its front and rear sides. In this way, the straw 16 on each measuring tool 20, 21 is supported without being biased in either the front or the back,
The measuring accuracy of the measuring tools 20 and 21 is good. Furthermore, since the straw 16 is weighed by the front and rear measuring instruments 20 and 21, even if only one of the measuring instruments measures excess or deficiency in the supplied amount, the switch mechanisms 18 and 19 will not operate, so that the tatami making device There is no unnecessary stoppage or operation due to excess or deficiency of the amount of oil, and therefore the entire process is made smoother.

As explained in detail above, according to the present invention, it is possible to always supply a fixed amount of straw to the bottom of the tatami-making machine, in the large arrangements, and in each of the above steps, and as a result, the amount of straw in each layer is always maintained. You can get a uniform tatami mat.
