Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for cutting out a typesetting member in a rug having a design adhesively typewritten on the surface of a pile fabric.

The above-mentioned rugs are highly practical as they can easily add designs such as letters and designs to the pile fabric to enhance its aesthetic appearance, but on the other hand, if the design part gets damaged with use, other pile fabric parts will be damaged. Even if the product is not damaged, the aesthetic appearance is impaired, and due to damage to the design part, the product value is lost and the product life is shortened.

Therefore, attempts have been made to manually cut and remove the typesetting member with an iron or a knife, but this requires a great deal of effort and cannot solve the above problem. In view of the above-mentioned circumstances, it is an object of the present invention to provide a device that can easily remove typesetting parts, thereby making it possible to avoid shortening the lifespan of rugs due to damage to design parts. Next, embodiments of the present invention will be described in detail based on illustrative drawings.

A device 3 for conveying a mat M such as a mat for wiping your feet, on which a typesetting section 2 for forming designs such as letters and designs is adhesively typesetting on the surface of a pile fabric 1 made of chemical fibers such as nylon or vinylon.
, a cutter 4 for cutting out the typesetting section 2 from the pile fabric 1;
, and a relative approach mechanism 6 is provided to raise the rug M during conveyance on the side approaching the cutter 4, so that the cutter 4 acts while conveying the rug M, and the end of the pile la is placed at the location where the typesetting member 2 is adhered. The rug typesetting cutting device is configured to cut the side and cut and remove the typesetting member 2 from the pile fabric 1.

The conveyance device 3 winds a plurality of round belts 6 around shaft pulleys 8 formed with grooves 7 at predetermined intervals in the longitudinal direction. A swing arm 101 on which a tension spring 9 is tensioned is actuated by a tension pulley 11 mounted on the shaft, and,
Three of the shaft pulleys 8 on the conveyance end side, and an output shaft 13 of the original work unit 12, which is equipped with a split boule-type continuously variable transmission and a worm gear-type reduction mechanism in the motor. are connected in motion via a chain 14, and the conveyance speed thereof can be changed dramatically.

The cutter 4 is constructed by winding a bandless blade body 18 around a motor 15 and a driven wheel body 17 that is displaceable in the distance direction with respect to the motor 15 and a driving wheel body 16, and A tapered roll 19 is provided in the middle of rotation, and acts to press and displace the proximal end of the blade 18 by pushing the two stepped side walls of the wheels 16 and 17, thereby preventing the blade 18 from coming off. It is configured.

Incidentally, a grindstone member is configured to be detachable from the tapered roll 19, so that the blade body 18 can be easily polished.

To configure the relative approach mechanism 5, an idler roller 21 is provided on the inner peripheral surface of the winding of the belt 6 corresponding to the lower side of the blade 18 so as to be slidable up and down. The rolling roller 21 and the air cylinder 22 are provided with a turnbuckle mechanism 23 so that the length can be adjusted freely, and are linked together via a link 24 and a swinging arm 25, and as the cylinder 22 expands and contracts, The rugs M are arranged to approach and separate from each other.

Idler rollers 27, 27 are provided above the shaft pulleys 8, 8 disposed on both sides of the idler roller 21, and are biased downward by a compression spring 26. The rug M is conveyed while being held between the idling rollers 27, 27, and the rug M is conveyed by the idling rollers 21.
When the rug M is raised, the rug M is deformed into a convex shape, and as shown in FIG. Apply the tip of the blade 18 to the adhesive area, and while directing the typesetting member 2 away from the pile fabric 1, in other words, cut it out well with one blade 18 as if scooping up the typesetting member 2. It is configured so that A guide 28 is provided so as to be continuous with the conveyance end portion of the conveyance device 3, and based on the detection of the end portion of the rug M transferred onto the guide 28, the typesetting member 2 on the rug M on the conveyance device 3 is A position detecting device 29 is provided, and an electromagnetic control valve V for the detecting device 29 and the air cylinder 22 is provided.
are linked via the controller 30, so that based on the detection result by the detection device 29, the relative approach mechanism 5
An automatic operation mechanism 31 is configured to automatically operate the typesetting member 2 and cause the cutter 4 to act on the rug M with the typesetting member 2 moved to a position corresponding to the cutter 4.

That is, a rug M on which typesetting members 2 are adhesively typesetting in the same pattern.
...... Then, typesetting member 2 is selected from the tip part calendar in the transport direction
Focusing on the fact that the width of the typesetting member 2 as well as the width of the typesetting member 2 itself in the transport direction are set to be approximately equal to each other, based on the detection of the end layer of the rug M, the typesetting member 2
The controller 301 detects the position of the typesetting member 2 and moves it closer to the cutter 4 by shortening the air cylinder 22. After the built-in calculation time has elapsed, the air cylinder 22 is extended to separate the rug M from the cutter 4.

The detection device 29 detects the degree of reception of reflected light with respect to the projected light using a phototube, and detects the end pupil of the rug M based on the difference in reflectance between the guide 28 and the pile fabric 1. It is.

As the detection device 29, for example, a light emitter is provided on one side of the upper and lower sides of the guide 28, and a light receiver is provided on the other side, and a hole is provided in the guide 28 to allow light to pass through. The end layer of the rug M may also be detected. Further, the detection device 29 is connected to the cutter.
At a location on the upper side of 4 in the conveyance direction, for the rug M,
The typesetting portion of the rug M on the conveyance device 3 is provided so as to project light over almost the entire length in the conveyance direction and to receive the reflected light accompanying it, and based on the difference in reflectance between the pile fabric 1 and the typesetting member 2, It may be configured to detect the position of the village 2, so that even if the rug M on which typesetting members 2 with different patterns are adhesively typewritten is conveyed in a jumbled manner, the typesetting members 2 can be cut out well. There are some advantages. Reference numeral 32 in the figure denotes a safety cover that covers the outer periphery of the cutter 4, and is configured to prevent scattering to the outside and ensure safety even if the blade 18 breaks unexpectedly. The conveying device 3, the cutter 4, and the relative approach mechanism 5 are all provided on a truck 33, and are configured to be easily moved.

After the typesetting member 2 has been cut and removed, the rug M can be prepared by applying a new typesetting member 2, or by cutting the pile end side of the entire surface of the pile fabric 1 with a cutter to make the pile height even. A new typesetting member 2 is adhesively typesetting on the pile fabric with the same pile height, and the typesetting material is recycled as a product.

Next, we will explain the survey results on the secondary market.

When we investigated the causes of defects in 400 foot-wiping mats with letters glued and typesetting that were collected as defective products from randomly selected regions, we obtained the results shown in the table below.

All items that fall under paragraphs 1, 4, 8, and 9 (4)
1.6%), a portion (10.0%) after dry cleaning of items that fall under items 2 and 3, and a portion (10.0%) of items that fall under item 7 after spray cleaning. A portion (2.1%) of a total of 53.7% was subjected to typesetting removal using the device of the present invention, and then the pile tips were cut and aligned, and it was found that 6% of the pile could not be recycled. However, nearly 90%, or 47.7%, was able to be recycled so that it could be distributed as a product again.

In other words, nearly half of the items that were recalled as defective were 4
It is clear that 7.7% of the recycled content can be recycled, which is extremely useful from an economic standpoint compared to the conventional method, which disposes of recycled waste as a waste that cannot be used in products.

Note that the present invention may be operated manually without having the automatic operation mechanism 31 as described above. Further, in configuring the relative approach mechanism 5, the conveying path of the conveying device 3 itself is provided with a path portion that curves the rug M as it is conveyed, and on the other hand, the cutter 4 is supported by a cylinder or the like, and the cutter 4 is 4 may be driven and displaced so as to approach the rug M.

In summary, the typesetting/cutting device for rugs according to the present invention includes a device 3 for conveying a rug M on which a design is adhesively typewritten on the surface of a pile fabric 1, and a blade 18 in the shape of an endless band. A cutter 4 is provided which cuts the typesetting member 2 from the pile fabric 1 by rotating its blade surface in a direction parallel to the surface of the pile fabric 1 and perpendicular to the direction in which the pile fabric 1 is transported in the parentheses. In order to cause the rug M to act on the cutter 41 in a convexly curved state, a mechanism 5 for bringing the cutter 4 and the rug M relatively close to each other is provided so as to be operable to separate them.

That is, the rug M is transported by the transport device 3, and the blade 18 of the cutter 4 acts on the rug M being transported so as to scoop up the typesetting member 2, and as a result, the pile fabric 1
Since the typesetting member 2 can be cut well with a single blade 18, a large amount of rugs M can be cut simply by feeding the rug M to the conveying device 3 and moving the cutter 4 and the rug M relatively close to or apart from each other. Typesetting can be easily performed in a short time, and since the rug M acts on the cutter 4 in a convex state, the blade 18 of the cutter 4 can be easily applied to the bonding area between the pile fabric 1 and the typesetting member 2. This allows the cut surface of the pile fabric 1 to be made in a state with less unevenness, and by further applying a surface finish or re-adhesive typesetting on the typesetting member 2, it is now possible to reuse it as a product, and as a whole,
The typesetting member 2 can be cut out easily and satisfactorily, and a decrease in the life of the rug M due to damage to the design portion can be avoided, and a device that is extremely useful in practice has been provided.
