Description

[Detailed description of the invention] (a) Industrial application field The present invention provides a method for manufacturing one rectangular carpet by pasting several regular-sized sheets together in a lapped manner, and the method. The invention relates to manufacturing equipment that automates the work of

(b) Conventional technology and four points in between: For example, rubber carpets used in the main body (expansion weir) of a Fabridam generally have a structure in which several fixed-length sheets are pasted together in a ruff shape. Conventionally, the fixed-length sheets were pasted together manually, resulting in poor productivity, difficulty in obtaining a homogeneous product, and the need for a large working space.

That is, as shown in Fig. 1, the current manual laminating method involves laying a fixed-length sheet 1 in a stretched state, then moving a hand-pushed or self-propelled laminating cart 2. Liner cloth 3 that protects the glued surface of the sheet you are about to paste
This method involves winding up the sheet and applying temporary pressure to the adhesive surface, and then re-rolling with a hand roller or the applied IEE roller 4. It requires one more worker and is not very efficient. In particular, Fabridam requires one to three layers of carpet depending on the l1lr11 and weir height, and it takes a great deal of time to manufacture the multilayer carpet.

In addition, since Fabridum repeatedly expands and collapses, the part where the carpet is pasted must be strong and reliable, but the manual pasting method, which relies on the operator's visual inspection and intuition, does not allow for the amount of glue to be removed. This tends to cause variations in pressure and pressure, resulting in uneven bonding strength).

In addition, the length of one sheet to be laminated is sometimes 50 m.
A large working space with a length exceeding f is required. In addition, although a clean working environment is required for quality control purposes, it is extremely difficult to satisfy this condition in a large canal production area.

(c) Means for solving the four problems The present invention has been made in view of the above, and its first purpose is to It is an object of the present invention to provide a method for manufacturing a laminated carpet that achieves productivity, quality, turnaround time, and reduction of work space.

A second object of the present invention is to provide a manufacturing apparatus that enables the automation of operations and further stabilization of quality using the above-described method.

Now, is the method of the present invention for achieving the first object described above?This method is based on a method in which a fixed-length sheet is placed between two cylinders arranged in parallel, and is then diagonally continuous with a constant degree of fineness. At the same time, the joined surfaces of the sheets coated with adhesive in advance are applied with a predetermined pressure to stick them together, and the layer obtained by the work on U or on top of that is further fixed in the same procedure. This method is characterized in that a plurality of layers of endless belt-like carpet with shaku sheets pasted thereon is cut at one point along a line perpendicular to the side edge of the sheet to obtain a rectangular surface carpet.

The principle of this method is illustrated in FIGS. 2 to 4 of the accompanying drawings.

That is, as shown in FIG. 2, the rolled sheet 1 of fixed length is rewound. After winding the side edge 1a around the cylinder 5 diagonally and continuously with a certain degree of fineness, and pasting the flat edge of the sheet on the cylinder with adhesive, it is removed from the cylinder. A cylindrical carpet 6 as shown in Figure 3
is obtained. next.

A line A perpendicular to the side edge 1a of the spirally wound standard length sheet 1 (at this time, one end 11 of the sheet 1) and the other end 1b'
If the sheet is aligned with line A, the sheet can be used without wasting it.) Cut one place along one line and spread the cut part horizontally to complete a rectangular laminated carpet 7 as shown in FIG.

However, as described here, if a fixed length sheet is spirally wound around one cylinder, intercondyle will occur in terms of practical use. This is because, when producing a long carpet, a cylinder with an impractically large diameter is required, and changes in the size (length) of the carpet cannot be accommodated.

Therefore, in the present invention, as shown in FIG. 5, two cylinders 8 and 8' are arranged in parallel, and the fixed length sheet 1 is spirally wound between both cylinders. By moving in parallel, the distance between both cylinders can be set arbitrarily, so the above-mentioned intercondylar problem can be eliminated. In addition, moving the two cylinders relatively closer to each other and moving them apart is as follows:
Although desirable, this is not necessary in the production of regular length carpets and is therefore not an essential requirement of the present invention.

According to the method of the present invention based on the above 1ift, it is sufficient to spirally wind a fixed-length sheet by rotating the cylinder at the same time as the roll-wound sheet traverses.

There is no need to stretch the sheet, adhesive can be applied continuously when the sheet is unwound, and the bonded portion of the sheets can also be continuously pressed in the opposite direction using a pressure roller or the like. It is also possible to automate the cutting of the sheets.Therefore, the carpet production is excellent, the quality is stable, and the work space can be reduced.

In addition, for laminated carpet with one or more layers, if the endless belt-like carpet is rolled around a cylinder, then before cutting it, cut the required number of standard-length sheets by rubbing the splicing position horizontally one time according to the above procedure. It can be easily obtained by rolling it up and pasting it with a pre-applied adhesive, and then cutting the laminated endless carpet at one point diagonally.

An example of an apparatus that automates the work according to method 1 above will be described below with reference to FIGS. 6 and 7.

This device is intended for manufacturing rubber carpets, and the reference numeral 10 in the figure is a fixed-length sheet supply device;
20 is a device for winding the sheet 1;

The supply device 10 includes a traverser 1 consisting of a cart 11b running on rails 11a and a drive mechanism 115 thereof.
1, an index table 12 provided on the trolley, a rewinding machine 13 for the rolled sheet 1 including a liner winding machine 13a provided on the table, and an adhesive for spraying or transferring adhesive onto required parts of the supplied sheet. Gluing machine 14
, dryer for coating adhesive 15. It consists of a presser roller mechanism 16 that presses the fixed length sheet at a set pressure in a fixed cylinder 1, which will be described later, and an index table 12.
The amount of sheet 1 to be fed out is adjusted by rotating one of the sheets 1, and after that, the winding of the sheet 1 is carried out one time so that five sheets are fed out while the cart 111) is moved horizontally at a speed of 1 point.

On the other hand, the winding device 20 arranged in front of the supply device is
It consists of a fixed cylinder 21 and a movable cylinder 22 parallel to it, and both cylinders 21, 22 are configured to rotate using a drive device (not shown). Further, the rotational speed C of each cylinder is adjusted by 1 to make them equal by electrically synchronizing the driving device.

The movable cylinder 22 changes the size of the carpet by moving it toward and away from the fixed cylinder 21. In the illustrated device, it moves automatically on the rail 23 in order to move in parallel accurately. It is provided on the moving trolley 24. The mechanism for moving the cylinder 22 may be a manual type using a drive screw with a rotating handle or the like. Furthermore, although it is desirable to drive both cylinders 21 and 22 as described above, it is sufficient to drive at least one of them.

Next, reference numeral 17 in Fig. 6 is a sensor that is placed in contact with the side edge of the sheet.For example, this sensor corrects the traverse speed by emitting a signal away from the side edge of the sheet. This method prevents the edges of the sheets from shifting at the joint portion.

Reference numeral 25 in FIG. 6 is a slack detection sensor that detects slack in the laminated sheet and sends a tension correction signal to the tension adjustment mechanism 18) consisting of a tension roller. The sheets are pasted together with this added.

In addition, between the cylinders 21 and 22 of the device consisting of the above, a cutting device 30 that is self-propelled on a guide rail 30b on which a cutting blade 30a is suspended diagonally is fixed at a fixed position or on a rail 30C as shown in the figure. If equipped to guide and move in parallel, cutting endless carpets can be done quickly and easily.
E: I can do one thing with certainty. Of course, this cutting work may be performed manually, and even in that case, the labor and time required to complete the carpet are greatly improved compared to the conventional method.

In addition, it is desirable to arrange a winding mechanism behind the moving cylinder to send the cut carpet to a subsequent process. Powder dusting device 3 for shaking powder for prevention
1 and a traveling cylinder 32 for winding and curing the carpet.

When the device 20 and the supply device 1o are driven, the obliquely fed sheet 1 is continuously spirally wound between the cylinders 21 and 22, and at the same time, the welded edges of the sheet are attached, with almost no need for manpower. You can produce one high-quality carpet in a short time. Particularly special: If the endless carpet is equipped with a cutting device and a winding mechanism, the entire work will be automated, resulting in higher productivity.

(E) Effects As described in Part 2, according to the method and apparatus of the present invention, one layer or multiple layers can be continuously formed without stretching a regular sheet and without requiring much manual labor. It is possible to produce laminated carpets, greatly improving productivity and reducing product costs.

In addition, when pasting sheets of standard length, the adhesive can be applied uniformly using a gluing machine, and the pressure on the pasting area can be applied evenly with a predetermined pressure using a presser roller, etc., so that the entire pasting force is reduced. A high-quality product can be obtained.

Furthermore, since the fixed-length sheet is spirally wound around two rolls and finally cut and expanded, one working space only needs to be about half that of the conventional method, making it easier to manage the work environment.
