FIGS. 10 and 11 show a conventional example of a building material floor manufacturing machine for manufacturing this type of building material floor. Among them, FIG. 10 is a longitudinal sectional front view showing principal parts in principle, and FIG. 11 is a schematic front view.

[0003] First, in FIG. 11, a base 1 of a building material floor manufacturing machine is provided with a needle base guide 2 which is located substantially at the center in the left-right direction in FIG. 11 and extends vertically. The needle base guides 2 are provided on both sides of the base 1 in the width direction (the direction orthogonal to the paper surface) to face each other. A needle table 3 is provided on these needle table guides 2 via a bearing 4 so as to be vertically movable.
(See FIG. 10) are arranged in the width direction (direction orthogonal to the material feeding direction A). Further, the base 1 is provided with a first lower roller 6a on the material inlet side (left side in FIGS. 10 and 11) with respect to the sewing needle 5, and the material outlet side (right side in FIGS. 10 and 11). Second and third
Lower rollers 6b and 6c are provided.

A roller plate 7 having a rectangular frame shape is disposed above the base 1 so as to be able to move up and down. The roller plate 7 is provided with the first, second and third lower rollers 6.
The first, second, and third upper rollers 8a, 8b, 8c, which are paired with a, 6b, 6c, are supported. Here, the first lower roller 6a and the first upper roller 8a constitute an entrance side feed roller 9a, and the second lower roller 6b and the second upper roller 8b constitute a first exit side feed roller. Roller 9
b, and the third lower roller 6c and the third upper roller 8c constitute a second outlet side feed roller 9c.

[0005] The roller plate 7 is provided with a pressing plate 5a located below the sewing needle 5. Handles 10 for raising and lowering the roller plate 7 are provided on both left and right sides of the base 1. This handle 1
0, the screw rod 12 oriented in the vertical direction rotates via the two bevel gears 11a and 11b, and the roller plate 7 is screwed forward and backward with the nut portion 13 screwed to the screw rod 12. The first to third upper rollers 8a, 8b, 8c move up and down along the screw rod 12, and the inlet-side feed roller 9a, and the first and second outlet-side feed rollers 9b, 9c. The vertical interval between the rollers can be changed. The feed operation of the feed rollers 9a to 9c on the entrance side and the exit side and the vertical movement (sewing operation) of the needle base 3 are interlocked.

FIGS. 10 and 11 show an example of a case where a state where a thin building material floor is manufactured as a building material floor is switched to a state where a thick building material floor is manufactured. Of these, the moisture-proof sheet 1 is used as a material for thin building material floors.
4a, the insulation board 14b, and the cushioning material 1
4c, which has a three-layer structure, and as a thick building material floor, a moisture-proof sheet 14a, two insulation boards 14b, a synthetic resin foam plate 14d disposed therebetween, and a cushioning material. 14c has a five-layer structure. Among the materials, the moisture-proof sheet 14a and the cushioning material 14c
Are unwound from the rolls 14aR and 14cR, respectively, but the other insulation board 14b and synthetic resin foam plate 14d generally used are formed to a predetermined size in advance. However, since there are many types of building material floors depending on the combination of materials, the present invention is not limited to this. A tension roller 15 is provided on the roll 14aR side of the moisture-proof sheet 14a, and a constant tension is applied to the moisture-proof sheet 14a by the tension roller 15.

In the above configuration, when manufacturing a thin building material floor, the height of the roller plate 7 is adjusted so that the interval between the upper and lower rollers of each of the feed rollers 9a to 9c corresponds to the thin building material floor. . Then, 1 is placed on the moisture-proof sheet 14a.
In a state where the insulation boards 14b are placed, they are passed between the upper and lower rollers of the entrance side feed roller 9a, and the cushioning material is placed on the insulation board 14b between the entrance side feed roller 9a and the holding plate 5a. 14c are arranged and pressed by the pressing plate 5a, and are passed between the upper and lower rollers of the first and second outlet side feed rollers 9b and 9c. In this state, while the material of the building material floor is intermittently fed in the direction of arrow A by the feed rollers 9a to 9c, the needle base 3 is moved up and down and sewn with the sewing needles 5. The sewn building material floor is sent out in the direction of arrow A from the second outlet side feed roller 9c.

In the case of manufacturing a thick building material floor,
The height of the roller plate 7 is adjusted so that the interval between the upper and lower rollers of each of the feed rollers 9a to 9c corresponds to a thicker building material floor. Then, with the insulation board 14b, the synthetic resin foam plate 14d, and the insulation board 14b placed in this order on the moisture-proof sheet 14a, these are passed between the upper and lower rollers of the entrance side feed roller 9a, and The cushioning members 14c are placed on the first and second outlet side feed rollers 9b and 9c while being pressed by the holding plate 5a.
In this state, the material of the building material floor is supplied to each of the feed rollers 9a-9c.
The needle table 3 is moved up and down while intermittently feeding in the direction of arrow A, thereby sewing with the sewing needles 5.

Here, the operation in the case of switching from a state where a thin building material floor is manufactured to a state where a thick building material floor is manufactured will be described. When manufacturing a thin building material floor, the material of the thick building material floor (insulation board 1
Even if the front end 4b of the synthetic resin foam plate 14d) reaches the left end of the roller plate 7, the distance between the upper and lower rollers of the feed rollers 9a to 9c cannot be increased by raising the roller plate 7. Then, even if the rear end e of the insulation board 14b of the thin building material floor currently being sewn passes through the sewing needle 5 and the sewing of the thin building material floor is finished, the rear end e is the third end. Until it reaches the outside (right side) of the feed roller 9c, the moisture-proof sheet 14a and the cushioning material 14
While continuing to feed c, the needle base 3 is moved up and down to continue sewing them with the sewing needle 5. This is because the material cannot be fed if the roller plate 7 is raised to widen the interval between the upper and lower rollers of each of the feed rollers 9a to 9c when the sewing of the thin building material floor is completed. is there.

The rear end e of the insulation board 14b
Reaches the outside of the second exit side feed roller 9c,
The feed operation and the sewing operation are stopped, the handle 10 is rotated to raise the roller plate 7, and each feed roller 9a
The distance between the upper and lower rollers 9c to 9c is increased so as to correspond to a thicker building material floor. At this time, the holding plate 5 also moves up together with the roller plate 7. In this state, the tip f of the thick building material floor material (insulation board 14b and synthetic resin foam plate 14d) is passed between the inlet side feed rollers 9a and pushed to the position where it is held down by the holding plate 5, and the feeding operation is performed. The sewing operation is started to start sewing the material of the thick building material floor.

Contrary to the above, when switching from a state in which a thick building material floor is manufactured to a state in which a thin building material floor is manufactured, the above-described case can be achieved only by reversing the moving direction of the roller plate 7. The operation is similar to

The conventional configuration described above has the following disadvantages. That is, in the case where the thickness of the building material floor to be manufactured is changed so as to be different, after the sewing of the previous building material floor is finished, the rear end e of the building material floor reaches the outside of the second outlet side feed roller 9c. Cannot move the roller plate 7 up or down.
a and the cushioning material 14c need to be fed idly. For this reason, that material is wasted.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a building material floor capable of minimizing waste of material when switching to make the thickness of the building material floor to be manufactured different. To provide a manufacturing machine.

[0014]

SUMMARY OF THE INVENTION In order to achieve the above object, an invention according to claim 1 includes a plurality of sewing needles arranged in a direction intersecting a feeding direction of a material, and An inlet-side feed roller, which is disposed at a portion on the material inlet side with respect to the lower roller and the upper roller, and a lower roller disposed at a portion on the material outlet side with respect to the sewing needle; And an exit-side feed roller forming a pair with the upper roller. A plurality of materials to be a building material floor are sandwiched between the upper and lower rollers of the entrance-side feed roller and the exit-side feed roller, and the sewing is performed. In a building material floor manufacturing machine configured to sew with a needle, an entrance-side roller plate that supports an upper roller of the entrance-side feed roller, and an exit-side roller plate that supports an upper roller of the exit-side feed roller, Inlet roller play Characterized in that the outlet-side roller plate was separately lifting configurable with.

In the above configuration, for example, when switching from a state of manufacturing a thin building material floor to a state of manufacturing a thick building material floor, the rear end of the material of the thin building material floor passes near the entrance side feed roller. Then, raise only the entrance-side roller plate so that the distance between the top and bottom of the entrance-side feed roller corresponds to the thickness of the later thick building material floor, and insert the material of the later building material floor between the entrance-side feed rollers. I do. Then, when the sewing of the earlier thin building material floor is about to end and the tip of the material of the later thick building material floor is near the sewing needle, the feed operation and the sewing operation are stopped, and the exit roller plate is raised. Then, the interval between the upper side and the lower side of the exit side feed roller is made to correspond to the thickness of the later building material floor, and sewing of the later building material floor is started.

Conversely, when switching from a state where a thick building material floor is manufactured to a state where a thin building material floor is manufactured, the rear end of the material of the thick building material floor is located on the entrance side. After passing through the roller plate, lower only the entrance-side roller plate so that the distance between the upper and lower sides of the entrance-side feed roller corresponds to the thickness of the later thin building material floor, and feed the material of the subsequent building material floor to the entrance side. Insert between rollers. Then, when the sewing of the earlier thick building material floor is completed, and the tip of the material of the later thin building material floor comes near the sewing needle, sewing of the thin building material floor is started. Then, when the rear end of the material of the thicker building material floor passes through the outlet side feed roller, the outlet side roller plate is lowered, and the gap between the upper side and the lower side of the outlet side feed roller is changed to the thickness of the thin building material floor. And continue sewing the building material floor later.

According to this, the inlet side roller plate and the outlet side roller plate can be raised and lowered separately, so that when switching to make the thickness of the building material floor to be manufactured different, it is possible to feed the material idly. And there is almost no need to waste material.

[0018] The invention according to claim 2 is a pressing plate which is provided below the sewing needle and is raised and lowered together with the outlet roller plate, and presses the material when sewing with the sewing needle. A temporary holding member provided so as to be movable relative to the sewing needle on the outlet side of the material and capable of moving to a position where the material is pressed at the time of sewing with the sewing needle. Things.

In the above-described configuration, when sewing, the material is normally sewn while being pressed by the pressing plate provided on the outlet roller plate. However, for example, when switching from a state where a thick building material floor is manufactured to a state where a thin building material floor is manufactured, the exit-side roller plate rises corresponding to the thicker building material floor, and the entrance-side roller plate becomes thinner. When sewing of a thin building material floor is started after sewing of a thick building material floor is completed in a state where it is lowered corresponding to the building material floor, a presser provided on an exit-side roller plate. In some cases, the plate is too high to hold the tip of a thin building material floor. If sewing is performed with a sewing needle in such a state, the leading end of the building material floor rises, and the sewing cannot be performed properly. Therefore, in such a case, the tip of the thin building material floor is pressed by the temporary holding member, so that the tip of the thin building material floor can be prevented from floating, and the thin building material floor can be prevented. The floor can be sewn well.

According to a third aspect of the present invention, there is provided a presser plate which is provided below the sewing needle and is raised and lowered together with the entrance-side roller plate, and presses the material when sewing with the sewing needle. It is characterized by having.

In the above configuration, since the holding plate for holding the material at the time of sewing is provided on the entrance-side roller plate, for example, a state where a thick building material floor is manufactured is switched to a state where a thin building material floor is manufactured. In some cases,
During the sewing of the thick building material floor, the roller plates on the entrance side and the exit side are in a state of being raised corresponding to the thick building material floor.
Then, after sewing up to the rear end of the thick building material floor, only the entrance-side roller plate provided with the holding plate is lowered corresponding to the next thin building material floor, and the next thin building material floor is sewn. The material is inserted, and the tip of the material of the thin building material floor is pressed by the holding plate. Thus, the material of the thin building material floor can be pressed by the holding plate, so that the thin building material floor can be sewn satisfactorily without the tip portion rising.

Contrary to the case described above, when switching from a state in which a thin building material floor is manufactured to a state in which a thick building material floor is manufactured, during the sewing of the thin building material floor, the entrance side and the exit side are sewn. Both roller plates are in a lowered state corresponding to the thin building material floor. Then, after sewing to the rear end of the thin building material floor, only the entrance-side roller plate provided with the holding plate is raised corresponding to the next thicker building material floor, and the material of the thicker building material floor is removed. The thicker building material floor is inserted by the insertion plate and the leading end of the thicker building material is pressed by the holding plate. Accordingly, the material of the thick building material floor can be pressed by the holding plate, so that the thick building material floor can be sewn satisfactorily without the tip part floating. Therefore, according to the third aspect of the present invention, since the holding plate is provided on the entrance-side roller plate, even when the thickness of the building material floor to be manufactured is changed to be different, the building material floor to be sewn is held down. There is an advantage that the pressing can be performed by the plate, and the temporary pressing member required in the second aspect of the invention can be eliminated.

In this state, the outlet handle 40 is rotated to raise the outlet roller plate 37, and the first and second outlet feed rollers 39a and 39b are moved. The distance between the upper and lower rollers is increased so as to correspond to a thicker building material floor. Then, the tip of the material of the thick building material floor is pressed by the pressing plate 45, and the feeding operation and the sewing operation are started, and the sewing of the material of the thick building material floor is started. Thereby, when switching from a state in which a thin building material floor is manufactured to a state in which a thick building material floor is manufactured, the material can be manufactured in a continuous state without skipping the material.

In this case, when the sewing is finished to the rear end e1 of the material of the thin building material floor, the feeding operation and the sewing operation are stopped, and only the entrance side roller plate 28 is adapted to correspond to the thick building material floor. Then, the material of the next thicker building material floor is inserted between the upper and lower rollers of the first and second inlet-side feed rollers 31a and 31b.
