Further, when the rod 12 of the small cylinder and the rod 13 of the large cylinder are extended at an equal speed, the hanger is pushed out between the net-like feed-out device 8 and a net-like member support device 20. When the net-like member feed-out device 8 is rotated to hook up the hanger, the net- like member 4 is guided onto the net-like member support device 20 which therefore, sets the net-like member 1, in the front of the left end of a cement chip board 1, on a conveyor belt 2.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to, for example, the manufacturing process of hard wood cement boards.
This invention relates to a mesh supply device used for separating surplus water from water.

Hard wood cement boards, which are obtained by mixing wood flakes, cement, water, etc. and molding the mixture into a board shape, are widely used as materials for the exterior walls of buildings.

This hard wood cement board is manufactured by, for example, Japanese Patent Application Laid-Open No. 56-140
058 @ As described in the publication, it is obtained by supplying a mixture of wood flakes, cement, water, etc. to a formwork placed on a mesh delivery device, and hardening this by heating and pressurizing it. .

If the excess moisture generated during this curing process is not removed,
Cavities or layer cracks occur in hard wood cement boards.

As a method for removing this excess moisture, a mesh such as a wire mesh is placed on the top surface of the mixture, and when pressurized with a press, moisture is removed from the voids of the mesh.

The work of placing the net on top of this mixture requires corner alignment, etc., and requires relatively skill. There are also a large number of net bodies to handle. Moreover, the mixture before hardening is easily deformed even by a slight force. It is necessary to quickly place the net without applying unnecessary force and remove it gently after separating the excess water. If the net is misaligned or wrinkled, dehydration may not be carried out sufficiently or the product may be damaged. However, no apparatus has been proposed that can sequentially place nets on the mixture that is continuously conveyed in this surplus water separation process.

The present invention has been made in view of the above points, and provides a net supply device that temporarily stores nets in a storage rack, takes them out one by one from the storage rack, and places them on a mixture. It is something to do.

That is, the net supply device of the present invention comprises: - a storage rack having parallel rails for suspending and supporting both ends of a rope body provided with hangers on its sides; a mesh feeding device for feeding out the mesh; an arm for pushing the hanger from the parallel rails of the storage rack and guiding it to the mesh feeding device;
It is characterized by comprising a net support device provided opposite to the net feed device.

The details of the present invention will be explained below based on the drawings showing one embodiment of the invention. In figure d3, reference numeral 1 indicates a wood cement material made of a mixture of wood flakes, cement, water, etc., which is developed on a template 3. It is placed in a mat shape.

This mat-like wood chip cement material 1 is being transported on a transport belt 2 in the direction of arrow a. Above the transfer belt 2 is a storage rack 5 that stores the net 4 for separating excess water.
Two of them are placed on the portable pedestal 6. Further, on the left side thereof, a mesh feeding device 9 is installed, and an endless belt 8 guided by four pulleys 7 is rotating in the direction of the arrow.

Above the storage rack 5, an arm 14 is arranged which is pivoted and supported at two points at the tips of the rods 12 and 13 of the small cylinder 10 and the large cylinder 11.

As shown in FIG. 2, the net body 4 is composed of a hanger 15 and a net 16 fixed on one side to the hanger.

Both are made of metal or plastic, and the net 1
6 uses a material with good flexibility. This net body 4 is suspended and supported by parallel rails 17 of the storage rack 5. When hanging, both ends of the hanger 15 are placed on the parallel rails 17, as shown in FIGS. 1 and 3. In FIG. 3, only one net 4 is placed on the parallel rail 17 for convenience of illustration, but a large number of nets 4 can be suspended as shown in FIG. 1.

On the other hand, a net supporting device 20 is installed opposite to the lower surface of the endless belt 8 of the net feeding device 9.

As shown in FIG. 4, the net support device 20 includes several support plates 18 and a back tension roll 1 provided between them.
It consists of 9. In addition, a pair of seven hooks 21 are attached to the endless belt 8 of the net feed-out device u9 at a predetermined pitch, and the distance between them is determined by the support plate 18 and the parallel rail 17.
It is set slightly wider than C.

The mesh supply device configured as described above operates, for example, as follows.

First, a storage rack 5 on which a large number of nets 4 are suspended is placed directly under the arm 14 by means of a portable pedestal 6, and is placed directly under the net feed device 8.
is placed near the top of the . Next, the large cylinder rod 13
is retracted, and the arm 14 rotates around the tip of the rod 12 of the small cylinder, and directs its tip behind the hanger 15 of the leftmost net 4. After that, the rod 12 of the small cylinder
When it contracts, the tip of the arm 14 comes into contact with the back surface of the net hanger 15, as shown in FIG. Further, when the rod 12 of the small cylinder and the rod 13 of the large cylinder extend at the same speed, the hanger 15 is pushed out between the net feeding device 8 and the net supporting device 20. When the net feeding device 8 rotates and the hook 21 hooks the hanger 15, the net 4 is guided in the direction of arrow C on the net supporting device 20 as shown in FIG. At this time, since the pack tension roll 19 is rotating in the direction of arrow d, the net 16 is flexible and does not wrinkle even if the net support device 20 is steeply inclined. Note that the hook 21 can be modified in various ways, such as a hook shape or a zipper shape.

The net feeding device 8 rotates at a speed substantially synchronized with the transfer belt 2 for the wood chip cement material 1, and the hook 21 places the hanger 15 just in front of the left end of the wood chip cement material 1 on the transport belt 2, and the net 16 is gently placed on the wood chip cement material 1. Then, when the hook 21 reaches the pulley 7 at the tip, it comes off from the hanger 15 and rotates upward.

The above operations are repeated one after another, and the net body 4 is continuously placed on the wood chip cement material F811.

Thereafter, as shown in FIG. 5, this wood chip cement monthly rate 1 is inserted between hot plates 22 and 22, pressurized by a press 25t, excess water removed, and molded and hardened.

After the storage rack 5 has finished supplying the net 4, it is transported on a portable pedestal 6 to a separately installed net recovery device or''.

In the net recovery device, the net 4 is removed from the molded wood cement board and suspended again on the parallel rail 17 of the storage rack 5.

In this way, the net 4 can be smoothly circulated through the line.

The portable frame 6 includes, for example, a panel 23 on which the storage rack 5 is mounted, a free roller 24 provided on the lower surface of the panel, a drive wheel 25 that moves the panel 23 in the transverse direction of the transfer belt 2, and a free roller 24. Air cylinder 26 for lifting rollers
It is composed of.

In this way, the storage racks 5 are sequentially fed into predetermined positions.

Further, the net body feeding device 9 can be modified in various ways, such as one in which hooks are attached to both edges of a belt, and one in which hooks are attached to a pair of chains at a predetermined pitch.

For the arm 14, instead of using a pair of large and small cylinders, an appropriate well-known crank device may be used, and it is also possible to convert it into a robot or the like.

The net supply device of the present invention described above is capable of placing a large amount of nets on a conveyed object running on a line without continuously applying unnecessary force.

Furthermore, there is no risk of wrinkles occurring in the net, and therefore high-quality hard wood cement boards and the like can be mass-produced.
