[Prior Art] Making a large number of spiral coils made of synthetic resin monofilament thread and other linear filament materials,
These spiral coils are arranged side by side, and the spiral arc portions of adjacent spiral coils are inserted alternately and meshed, and the core hole is passed through the common hole created by the meshing to form a belt-shaped body that is flat and continuous. It has excellent durability and dimensional stability, and is effectively used for various purposes such as papermaking dryer cans, papermaking wires, and conveyor belts.

Incidentally, examples of the invention described for the papermaking canpus include JP-B-60-45400 and JP-B-56-78897.

[Problems to be solved by the device]

Various proposals have been made for a method of manufacturing the above, and in the above-mentioned Japanese Utility Model Laid-Open No. 56-78897, it is proposed that the circular arc portions are brought into contact with each other and press-fitting is sequentially repeated. This may hinder efficient mass production.

In manufacturing the above strip, it is a problem how to smoothly slide the circular arc portions of the adjacent spiral coils into the gaps between the circular arc portions of one spiral coil. Campus can produce acceptable marks on paper.

Another problem is how to smoothly insert each core wire into each of a large number of common holes. If the core wire is twisted, it cannot be smoothly inserted into the common hole.

The present invention is intended to provide a spiral mesh manufacturing apparatus that does not cause such a problem.

The above and other objects and novel features of the present invention will be apparent from the description of the present specification and the accompanying drawings.

[Means for solving the problem]

The present invention for achieving such an object is a spiral mesh for papermaking, in which a large number of spiral coils (spiral coils) are meshed in parallel and a core wire is inserted into each of a plurality of common holes formed by the meshing to form a spiral mesh. In a manufacturing apparatus, a spiral coil feed guide part for vertically separating and guiding two or more spiral coils and an upper spiral coil between the adjacent spiral coils on the lower side of the spiral coil separated vertically. Spiral coil stacking and transferring section that transfers to the spiral coil meshing and sending section in the next process, spiral coil meshing and sending section that simultaneously presses and stacks the stacked upper and lower spiral coils and sends out to the mesh processing section in the next process, and many core wires Core heat set A core part, a core wire passing roller part for passing the heat-set core wire between the rolls, and a core wire passing through the core wire passing roller part are arranged so as to be insertable into a common hole formed by the meshing of the spiral coil. A spiral for papermaking, comprising: a core wire aligning part; and a mesh processing part for simultaneously inserting the aligned multiple core wires into a large number of common holes of the meshing spiral coil sent from the spiral coil meshing sending part. It exists in the mesh manufacturing equipment.

[Action]

The operation of the present invention will be described with reference to preferred embodiments.

The main parts of the spiral mesh manufacturing apparatus according to the present invention are roughly divided into a part in which a large number of spiral coils are meshed in parallel, a part in which a large number of core wires are aligned while taking a habit, and a space between the meshed spiral coils. The common hole has three parts, that is, a mesh-processed part through which the core wire is inserted.

In the present invention, the spiral coil feed guide portion that separates and guides the spiral coil vertically and the spiral coil that is vertically separated are adjacent to each other on the lower side. A spiral coil stacking and transferring section that stacks and transfers an upper spiral coil between spiral coils and a spiral coil meshing and sending section that simultaneously presses and stacks the stacked upper and lower spiral coils and sends them out.

That is, in the present invention, a method is adopted in which a plurality of spiral coils are superposed on a plurality of lower spiral coils, and these are engaged with each other. The spiral coil feeding jig having such a structure that the upper spiral coil is superposed one by one between the lower spiral coils by shifting the position of the spiral coil Coil
In the spiral coil intermeshing feed-out section in the next step, it is pressed between two rolls. As a result, the upper and lower spiral-shaped continuous spiral coil arc portions are satisfactorily engaged, and in a single step, a combination of flat spiral coils having a plurality of spiral coils arranged in parallel and having a plurality of common holes is formed. Can be obtained.

In the present invention, as described above, a spiral coil feed guide is used in the spiral coil feed guide section so that the spiral coils are vertically stacked and meshed with each other so that a large number of spiral coils can be separated and guided vertically. ing.

The spiral coil combination having the plurality of common holes has a core wire passing through each of the common holes to form a spiral mesh, but a monofilament thread made of synthetic resin is used for the core wire, and the core wire is bent. In such a case, it is difficult to properly insert the elongated core into the long common hole of the above-mentioned combination, and it is necessary to align a large number of core wires with the common hole position.

In the present invention, as a portion for aligning while taking a habit of the large number of core wires, the core wire heat set part for performing heat setting and the heat set for the core wire provided from a large number of bobbins and tensioned by a tension roll. A core wire passing roller portion for passing the formed core wire between the rolls, and a core wire aligning portion for aligning the core wire passing through the core wire passing roller portion so that the core wire can be inserted into the common hole of the spiral coil combination.

By performing the heat setting and passing the tip end portion of the core wire between the rolls of the core wire passing roller portion, the entanglement of the core wire is removed, and the tip end portion is easily inserted into the common hole.

And, in the core wire aligning unit, the core wires are aligned at a certain interval and the core wire threading jig having a structure that can be transferred to the mesh processing unit is used. It will be properly inserted into a large number of common holes.

That is, in the present invention, the meshed spiral mesh assembly having a large number of common holes is preferably transferred from one side of a mesh processing unit formed of a mesh processing table arranged at the center, From the other side of the above, a large number of aligned core wires are sent out and the spiral mesh is manufactured on the mesh processing table, and on the mesh processing table A spiral mesh having an appropriate width can be obtained in one step.

As described above, according to the present invention, it is possible to easily obtain the spiral mesh by the spiral mesh manufacturing apparatus which has been devised in various ways, and the obtained spiral mesh is smooth and hardly causes harmful marks on the paper. Stability,
It excels in running stability.
