DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat disassembly for separating and disassembling a mat having a built-in internal structure such as a spring body used in a bed or the like into a surface layer such as a cloth or leather material and an internal structure. It relates to a processing device.

[0002]

2. Description of the Related Art Conventionally, when a mat having a spring body incorporated therein, such as a bed, is separated and disassembled into a fabric portion and a spring body, an operator cuts the fabric portion with a knife or the like.
By separating this from the spring body, the cloth part and the spring body are separated and dismantled. As an apparatus for performing this separation and disassembly, Utility Model Registration No. 3057661 is used.
A mat disassembly processing device described in Japanese Patent Application Laid-Open Publication No. HEI 9-163456 is known.

As shown in FIG. 8, a mat disassembly processing apparatus described in Japanese Utility Model Registration No. 3057661 has a mat transfer conveyor 51 for transferring a mat A, and an outlet side of the mat transfer conveyor 51. A pair of cloth take-up rollers 52 arranged at intervals so that the mat A can pass through
And a guide roller 53 that guides the spring body 56 wound around the fabric portion 57 by the fabric portion winding roller 52. The pair of cloth winding rollers 52 are provided with a required number of cut claw pawls 54 for cutting the cloth at predetermined intervals in the axial direction.

In such a mat disassembly processing apparatus, both edges of the cut for the cut of the mat A are held by the pair of the cut-off nails 54 for the cut for the cloth on the pair of cloth take-up rollers 52. In this state, when the cloth winding roller 52 is rotated in the direction of the arrow shown in the drawing, the cloth 57 of the mat A is cut and wound by the pair of cloth winding rollers 52, so that the mat A is simultaneously moved to the unloading side. By sending it out, the internal spring body 56 and the fabric portion 57 can be separated and disassembled.

[0005] Here, the cut biting claw 54 for cutting the cloth portion is
By operating the lever 55a, the claw body is operated to the open side and the bite side against the contraction force of the spring. Also,
The lever 55a of the claw body is formed by a hollow cloth winding roller 52.
And protrudes outward from a slit portion provided on the shaft circumference of the mat A, and holds the cloth portion 57 of the mat A together with the hook body 55b.

[0006]

In the mat dismantling processing apparatus having the above-mentioned structure, when the cloth portion 57 of the mat A is held by the cloth take-up roller 52, the hook 55b and the lever 55a are connected to the cloth as shown in FIG. When the fabric portion 57 is wound, the fabric portion 57 is wound around the hook body 55b and the lever 55a. Therefore, the fabric portion 57 is detached from the outer peripheral edge of the fabric take-up roller 52 as shown in the figure, and is wound up in a greatly expanded state.

When the fabric portion 57 is wound up in a greatly expanded state, the distance from the rotation center of the fabric take-up roller 52 to the fabric winding position is not constant.
Winding is not performed smoothly. Further, since a required number of the cut-off biting claws 54 for cutting the cloth portion are provided at a predetermined interval, only a portion of the cut-off biting claw 54 for the cut portion of the cloth portion is wound. It will be in an inflated state. Therefore, the fabric portion 57 is not wound up uniformly, and the surface of the wound up fabric portion 57 becomes uneven by the required number of the cut tearing claws 54 for fabric cutting.

Therefore, in the present invention, the operation for separating and disassembling a mat used for a bed or the like into a surface member such as a fabric portion and an internal structure such as a spring member is facilitated, and the surface member is smoothly wound. Provided is a mat dismantling processing device capable of being taken off.

[0009]

SUMMARY OF THE INVENTION A mat dismantling apparatus according to the present invention includes a pair of take-up rollers for winding a surface layer from a mat containing an internal structure, and separates the mat into a surface layer and an internal structure. A mat dismantling processing device for dismantling,
Each of the pair of winding rollers is provided with a pair of gripping portions for gripping both end portions of the surface layer body, and the gripping portion intersects with the concave or convex portion formed on the winding roller and the concave or convex portion to form the surface layer body. It is characterized by comprising a low arm to hold down and a lever for tilting the arm toward the concave portion or the convex portion.

[0010] Thereby, the surface layer body of the mat wound by the winding roller is gripped by the pair of gripping portions from the outside at both ends. At this time, since the lever for operating the arm constituting the gripping part is also disposed outside the pair of gripping parts, the lever does not interfere with the winding of the surface layer onto the winding roller, and the lever of the pair of gripping parts does not interfere. Since there are no irregularities between them, the surface layer is almost uniformly wound up with only a slight bulge of the short arm crossing the concave or convex portion.

Here, it is desirable that the holding portion is slidable in the axial direction of the winding roller. For example, mats used for beds and the like are available in single-size and double-size mats, so they can be used for mats of various sizes by sliding the grip according to the size of the mat. It is possible to

The 0 and 11 arms 15a are tilted inward from the outside of the pair of grips 10 and 11.

Next, the operation of dismantling the mat 20 by the above-configured mat dismantling apparatus will be described. FIG. 6 is a view showing an example of a mat in which cuts are made in the cloth on the front side in the transfer direction, and FIG. 7 is a state in which the mat is transferred in an upright state between a pair of take-up rollers 2a and 2b to wind up the cloth. It is the schematic plan view which showed the process.

The mat 20 having a spring body 20b as an internal structure is provided on the fabric 20 on the front side in the transport direction.
In FIG. 6A, a cutting notch 21 as shown in FIG. 6 is provided by a knife or other appropriate means prior to the dismantling process. Then, as shown in FIG. 7, the mat 20 having the cuts 21 provided on the cloth on the front side in the transfer direction is transferred between the pair of winding rollers 2 a and 2 b by the roller conveyor 1.

Next, the upper end edges 22a, 22b of the cut 20 of the cloth 20a of the mat 20 are gripped by the grippers 10, 10 of the pair of winding rollers 2a, 2b. The grippers 11, 11 are gripped by the grippers 11, 11. The gripping portions 10 and 11 hold the cloth 20a over the bars 14a and 14b while tilting the lever 15b to the outside of the cloth 20a so that the arm 15a tilts onto the cloth 20a and the bars 14a and 14b. This is done by interlacing between 14b. Thereby, the fabric 20a is
It is gripped in a state of being caught by the intersecting bars 14a, 14b and the arm 15a.

In this state, when the take-up rollers 2a and 2b are respectively rotated in the directions of the arrows in FIG. 7, the fabric 20a of the mat 20 is taken up while being cut off by the take-up rollers 2a and 2b. The spring body 20b as a body is sent to the free roller 3 side.
Thereby, the mat 20 is separated and disassembled into the internal spring body 20b and the fabric 20a.

The cloth 20a wound on the pair of winding rollers 2a and 2b in this manner is rotated in a reverse direction to pull out the cloth 20a to the outside, and finally the cloth 20a is cut. The edge 22a of the cut 21
22b, 23a, and 23b are used as levers 1 of the grippers 10, 11.

0 of the fabric 20a has both end edges 22a, 22b, 23
a and 23b are gripped from outside by the grippers 10 and 11, respectively. At this time, since the lever 15b for operating the arm 15a constituting the gripping portions 10 and 11 is also disposed outside the fabric 20a, the lever 15b may interfere when the fabric 20a is wound on the winding rollers 2a and 2b. In addition, since there is no unevenness between the pair of gripping portions 10 and 11, the fabric 20a is almost completely bulged only by a slight bulge of the short arm 15a intersecting with the bars 14a and 14b from the bars 14a and 14b. It is wound up uniformly.

The operation of gripping and removing the fabric 20a from the gripping portions 10 and 11 is performed by using the lever 1 of the toggle clamp 15.
This is extremely easy because it is possible only by the tilting operation of 5b. Further, since the fabric 20a is almost uniformly wound around the winding rollers 2a and 2b with only a slight swelling, the winding and removal of the fabric 20a around the winding rollers 2a and 2b is smooth, and the fabric 20a and the Separation and disassembly operation with the spring body 20b can also be easily performed.

Further, the gripping portion 10 is provided with the winding rollers 2a,
Since it is possible to slide in the axial direction of 2b, it is possible to use it corresponding to mats of various sizes by sliding this gripping part 10 according to the size of the mat to be separated and dismantled. . In the present embodiment, only the grip 10 is configured to be slidable in the axial direction, but it is also effective to configure the grip 11 to be slidable as well.

In the present embodiment, holes (holes) are formed on the winding rollers 2a, 2b instead of the recesses formed by the bars 14a, 14b on the winding rollers 2a, 2b.
It is also possible to provide a concave portion by forming.
Further, the relationship between the concave portion and the convex portion on the winding roller 2a side and the toggle clamp 15 side can be reversed.
