Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for loading and conveying undried veneers that have been subjected to a textile printing process, and the gist thereof is that each chain plate constituting a chain conveyor 2 for conveying a printed veneer 1 An annular liquid pool groove 4 is provided on both sides of the chain plate 3 at a distance from the outer peripheral surface of the chain plate 3.
The printing veneer conveying apparatus is characterized in that a rotating brush 5 for cleaning the outer peripheral surface and both side surfaces of each chain plate 3 is provided on the return side of the chain conveyor 2.

In the process of preheating the printed veneer 1 on which the printing liquid has been applied, the printing liquid on the surface adheres to the surface of the conveying chain conveyor 2' as shown in Figure 1, and the attached printing liquid is solidified by heat at the outlet of the preheater in the preheating process. When the chain conveyor 2' rotates and the next printed veneer is loaded and conveyed, the printing liquid applied to the veneer 1 adheres to the surface of the chain conveyor 2' at the beginning of conveyance, and this newly attached The solidified printing dye that has already adhered to the surface of the chain conveyor 2' is dissolved by the water content of the printing liquid, but it is solidified again by heat at the outlet of the preheater in the preheating process. In this way,
As the amount of printing liquid that adheres to the surface increases, the amount of new printing liquid that adheres to the surface that dissolves due to moisture also increases, and the effect on staining the veneer 1 gradually becomes greater, and the printing liquid also increases in the chain. It gradually flows from the surface of the conveyor 2' to both sides.
Then, the printing dye solidifies on both sides, and the printing dye generated on both sides also melts due to the moisture of the newly attached printing liquid in the early stage of preheating and adheres to the veneer 1. become. Therefore, at this stage, the stain on the veneer 1 has reached a level that cannot be ignored.

Conventionally, the surface of the chain conveyor 2' is cleaned with a mop or rag 6 as shown in Fig. There is no problem if it is about 1 batch = 150 sheets, but if you wash the veneer 1 more than that, the veneer 1 will get dirty to an extent that cannot be ignored. The reason for this is that the cloth or mop 6 can only clean the surface of the chain conveyor 2', but not both sides of the chain conveyor 2'.
After cleaning, about 1 to 2 batches of newly attached printing liquid will initially adhere to the surface of the chain conveyor 2' and have little effect on the solidified printing dye on both sides of the chain conveyor 2'. In addition, only the printing liquid newly attached to the surface of the chain conveyor 2' affects the veneer 1, and the amount of printing liquid that affects the veneer 1 is small, and although it is not noticeable in appearance as dirt, The printing dye that solidifies on the surface of the chain conveyor 2' gradually grows, and when this melts and dissolves the printing dye that has already adhered in large quantities to both sides, it flows to the veneer 1 side. As a result, dirt becomes noticeable on the veneer 1.

The present invention has been made in view of the drawbacks of the conventional examples described above, and its purpose is to completely clean the printing liquid around both sides of the chain plate, which could not be removed by conventional cleaning methods, using a rotating brush. To provide a printed veneer conveying device which can prevent the printing liquid from easily flowing out onto the chain conveyor surface due to the liquid pool grooves on both sides of the chain plate, and can therefore reliably prevent contamination of the veneer. There is something to do.

Hereinafter, the present invention will be explained in detail with reference to the accompanying drawings. Reference numeral 2 designates a chain conveyor forming a veneer conveyance line on which undried veneers 1 that have been subjected to textile printing are loaded and sent, with the upper side serving as the sending side and the lower side serving as the return side. Further, this chain conveyor 2 is used in the process of preheating the textile printed veneer 1, and is already preheated. As shown in FIG. 4, a rotating brush 5 made of synthetic resin is installed on the return side of the chain conveyor 2', and this rotating brush 5 and the chain conveyor 2 are not in contact with each other during textile printing and when drying the light-colored veneer 1. . When cleaning the conveyance line after textile printing is completed, the rotating brush 5 and the chain conveyor 2 are brought into contact with each other to perform cleaning. This rotating brush 5 is rotating at high speed, and due to the centrifugal force, the rotating brush 5 becomes stiff and strongly hits the chain conveyor 2, rubbing the chain conveyor 2. In this way, the chain conveyor As shown in FIG. 7, each chain plate 3 of No. 2 is cleaned by being rubbed about half of its outer peripheral surface and both side surfaces in the height direction (shaded area in FIG. 8). Note that the amount of cleaning required can be determined by adjusting the position and amount of rubbing.

The chain conveyor 2 is made up of a large number of chain blocks 7 connected together by pins, and each chain block 7 has a pair of chain plates 3 on both sides of which are spaced apart from the outer peripheral surface of the chain plates 3, as shown in FIG. An annular liquid reservoir groove 4 is carved therein.

Therefore, the rotating brush 5 can scrape off the printing liquid not only on the outer circumferential surface of each chain conveyor 3 but also on both side surfaces, making it possible to clean the grooves 4 away from the surfaces of both sides. Even if there are areas that could not be cleaned, or solidified printing liquid that was pushed away from the surface by the rotating brush 5 during cleaning, the liquid will not flow here. It is stopped by the groove 4, which is a liquid pool, and furthermore, even if the solidified material due to the moisture on both sides melts, it is stopped by the groove 4, which is a liquid pool, and does not flow to the veneer 1 side, resulting in a defective veneer 1. You can avoid it.

The veneers 1 that have been subjected to the printing process in this manner are suctioned one by one and conveyed to the next stage. At this time, a veneer suction and conveyance device 8 as shown in FIG. 9 is used. That is, 9 is a suction hood for vacuuming the inside and suctioning the veneer 1, and then moving and conveying the veneer. On the lower surface of the suction hood 9, there is a sponge body 10 whose lower surface is curved in an arched manner. This sponge body 10 is also provided with a suction hole 11b at the same position as the suction hole 11a of the suction hood 9. Then, as shown in FIGS. 10a to 10d, the suction hood 9 is lowered from above the veneer 1,
The sponge body 10 is crushed flat between the veneer 1 and the veneer 1 is adsorbed. Next, when the suction hood 9 is raised while adsorbing the veneer 1, the sponge body 10
bends the veneer 1 that has been elastically restored and adsorbed into a bow shape, and if two or more veneers 1 are adsorbed, the lower veneer 1 will bend due to the elasticity of the veneer 1 trying to flatten. It peels off from the veneer 1 on top of the veneer 1, thereby preventing the veneer 1 from being fed in two pieces.

Further, the veneers 1 are stacked and pressed by the press device 12. In this case, a predetermined number of veneers 1 are stacked outside the press device 12, and then carried into the press device 12, where the veneers 1 are further stacked in many tiers. The veneer 1 is pressed in the press device 12 in the following manner.
The veneer 1 can be set so that no misalignment occurs. Reference numeral 13 denotes a molding frame with an open top and bottom, grooves 14 are provided on both sides of the lower part of the molding frame 13, and a bottom plate 15 formed in an arch is provided on the lower surface of the molding frame 13 so as to be freely drawn out. A positioning guide 16 is suspended below the groove portion 14 . 17 is glow. 18 and 19 are upper and lower molds of the press device 12. However, the press device 12
Outside, the veneers 1 are delivered into the forming frame 13 and a predetermined number of veneers 1 are set. For a predetermined number of veneers 1, the glow 17 prevents the ends of the veneers 1 from rebounding. This veneer 1 is carried into the press device 12, set together with the forming frame 13 on the lower mold 19, the bottom plate 15 is pulled out, the upper mold 18 is lowered, and the veneer 1 is pressed. Next, when the upper mold 18 is raised and opened, the molding frame 13 is lifted by the clamp jig 20 of the upper mold 18 and separated from the laminated product on the lower mold 19. The clamp jig 20 comes off at the upper mold 18 upper limit, and the molding frame 13 is taken out of the press device 12. Furthermore, the veneer 1 set in the forming frame 13 is carried in and stacked on top of this laminate, and the positioning guide 16 of the forming frame 13 is applied to the edge of the laminate below to position the veneer 1. After this, the bottom plate 15 is pulled out from the molding frame 13,
The upper die 18 is lowered and pressed to obtain the final laminate. The molding frame 13 is removed when the upper mold 18 is raised.

As described above, the present invention has an annular liquid pool groove carved on both sides of each chain plate constituting a chain conveyor for transporting textile veneer, spaced apart from the outer peripheral surface of the chain plate, and each chain plate on the return side of the chain conveyor. Since it is equipped with a rotating brush for cleaning the outer peripheral surface and both sides of the chain plate, it is possible to use the rotating brush to clean the printing liquid on both sides of the chain plate, which could not be removed by conventional cleaning methods.
Furthermore, the grooves are formed by areas on both side surfaces that were not sufficiently cleaned by the rotating brush, or by the solidification of printing liquid that was pushed away from the surface by the rotating brush during cleaning. Even if there is something, the grooves, which are liquid pools, will stop the liquid from flowing here.Furthermore, even if something solidified by moisture on both sides melts, it will be stopped by the grooves, which will become liquid pools. It does not flow to the board side and does not cause veneer defects.
