[0002]
[Background technology]
In recent years, attempts have been made to give synthetic resin moldings surface characteristics similar to natural wood and to use them as various furniture, daily necessities, or interior parts of houses.
As such a technique, there is “cellulosic fine particles, wood-like molded article, and wood-like product” described in PCT Jp94 / 00351 (International Publication Number: WO94 / 20280).
[0003]
In the known technology, a pulverized powder obtained by pulverizing a cellulose material as a raw material is ground to obtain a granule having an increased bulk specific gravity, and the outer peripheral surface of the granule is smaller in diameter and harder than the granule. The surface grains are fixed to form fixed grains, and the resin and pigment are mixed and melted in the fixed grains, and thereafter or simultaneously with melting, they are formed into a desired shape by extrusion molding or injection molding. Then, it is possible to produce a wood-like product having a pattern very close to the surface of natural wood and having a texture such as a touch feeling close to that of natural wood.
By the way, the above wood-like product is further subjected to surface coating treatment after extrusion molding, followed by drying treatment.
[0004]
[Problems to be solved by the invention]
In the above-described conventional apparatus for producing a wood-like product by extrusion (extrusion-molded product production apparatus), the coating process is continuously performed, but the drying process is a separate line.
Therefore, the wood-like product after the completion of the painting process has to be separately transported to a drying device, and there is a problem that the work becomes complicated and the work efficiency is poor.
Also, since the drying process requires a certain amount of time compared to other processes, if it is continued to the painting process, the drying equipment itself must be enlarged to ensure the necessary drying time. If a lot of site area is required to install the equipment, or conversely, if the extrusion speed is set according to the size of the drying equipment, the performance of the extrusion molding machine cannot be fully utilized in some cases and the production efficiency is reduced. There is also the problem of falling.
[0005]
  The present invention has been made in order to solve the above-mentioned problems, and is an extrusion product manufacturing apparatus excellent in work efficiency by continuing a drying process in a manufacturing process of an extrusion product molded by extrusion molding. In addition, an object of the present invention is to provide an extruded product manufacturing apparatus that does not reduce the apparatus installation efficiency and production efficiency even if a drying apparatus is continuously provided..

Further, since the two loop chains 67 and 67 move in synchronization, the movement holding portions 63... Move in conjunction with the movement of the loop chains 67 and 67.
Therefore, for example, the movement pitch of the movement holding parts 63 can be synchronized with the production pitch per one extrusion-molded product by the extrusion machine 3.
[0032]
Here, since the support rod 65 is rotatably supported by the loop chains 67 and 67 and the mounting portion 66 is also rotatably supported by the support rod 65, the loop chains 67 and 67 are moved on the track.

At this time, the timing for carrying in the drying area 61 is set in advance so as to be when the placement unit 66 of the movement holding unit 63 is located between the rollers 62 a of the carry-in unit 62.
Then, the extruded product S carried into the carry-in part 62 is placed on the bottom surface part 66a of the placement part 66 as the movement holding part 63 moves up, and is moved along the track of the loop chain 67 as it is. The
[0037]
Next, after a predetermined time has elapsed, when the movement holding unit 63 on which the extruded product S is placed on the placement unit 66 moves downward and the bottom surface portion 66a attempts to move below the roller 64a of the carry-out portion 64, the bottom surface The extruded product S is transferred from the portion 66a to the roller 64a.
Subsequently, the extruded product S transferred to the roller 64a is conveyed outside the drying device 6 by the rotation of the roller 64a.
Then, the empty movement holding unit 63 moves horizontally downward and again moves to the carry-in unit 62, where the extruded product S newly transported from the coating apparatus 5 is placed.
[0038]
