Description

[Detailed Description of the Invention] The present invention relates to pneumatic conveyance equipment that conveys laundry such as wet towels and diapers through air suction, and sorts and conveys soiled laundry to predetermined locations in a cleaning factory.

Conventionally, the sorting of laundry in a cleaning factory has relied on transport using conveyors or carts, which requires a large number of personnel and takes up a lot of space, such as the installation location of the conveyor and the space required to move the cart. The inside of the factory was cramped.

In addition, arranging multiple conveyors and carts tends to make the entire facility complicated, and a satisfactory work management system is not provided.

The present invention was devised in view of these drawbacks, and includes a pneumatic pipe 1 having a plurality of input ports 2 at its starting end and connecting a predetermined hopper at its terminal end, and each switching valve 4 installed inside the pneumatic pipe 1. A plurality of branch pipes 6 are connected to each other through a plurality of branch pipes 6, and each of the branch pipes 6 is connected to the terminal end of the pneumatic pipe 1, and each of the branch pipes 6 is connected to the terminal end of the pneumatic pipe 1, and each of the branch pipes 6 is provided with an opening/closing lid 8. A plurality of hoppers 7 each having a blocking member therein for blocking advancement, the hoppers 7
A plurality of bypass pipes 10 connected to each one and provided with a response valve 14.
It is intended to provide air conveyance equipment for laundry comprising an intake pipe 11 connected to the bypass pipe 10 and provided with a blower 12 at the end thereof.

To explain the drawings showing the embodiment of the present invention, Fig. 1 shows the overall layout of the air conveying equipment, and 1 is provided with a plurality of input ports 2 equipped with lids 3 at the starting end, and at the terminal end. It is a long single pipe pneumatic pipe that connects predetermined hoppers, and a switching valve 4 pivoted by a shaft 5 is installed at each predetermined location of the pneumatic pipe 1, and a plurality of branches are provided from the position of the switching valve 4. Connect the tubes 6 respectively,
The pneumatic pipe 1 and the branch pipe 6 are alternately opened and closed by operating the switching valve (see FIG. 2).

Each branch pipe 6 and the terminal end of the pneumatic pipe 1 are connected to a plurality of hoppers 7 each having an opening/closing lid 8 pivoted on a shaft 9 at the lower end. The bypass pipe 10 has a blower 12 operated by a motor 13 at its terminal end.
The intake pipes 11 are each connected to a long single-tube intake pipe 11 provided with.

FIG. 3 shows the main part of the present invention in which valves 14 are provided at each stage in each bypass pipe 10 connecting each hopper 7 and an intake pipe 11, and the valves 14 are installed in each stage of the bypass pipe 10, which connects each hopper 7 and the intake pipe 11. When transporting the laundry a by suction, by closing the valve 14 of the full hopper 7 and opening the opening/closing lid 8, the stored laundry a can be taken out and the open lower end of the hopper 7 and the bypass pipe can be removed. 10 to the suction pipe 11, and the air can be continuously suctioned and conveyed without reducing the air suction force to other hoppers 7.

FIG. 4 shows an embodiment of the hopper 7, which is equipped with an opening/closing lid 8 and a blocking member that connects the branch pipe 6a and the bypass pipe 10a, and prevents the forward movement of the laundry a without interfering with the flow of suction air. A barrel baffle plate 15 is installed inside, and the laundry a conveyed by the suction air flowing from the branch pipe 6a through the hopper 7 to the bypass pipe 10a is hit against the baffle plate 15, which is a blocking member, to reduce the speed. After being lowered, it is dropped and stored in the hopper 7.

FIG. 5 shows another embodiment of the hopper 7, which is equipped with an opening/closing lid 8 to connect the branch pipe 6b and the bypass pipe 10b, and a lower part of the branch pipe 6b located inside the hopper 7.
A basket 16 is formed inside the hopper 7 and is provided with multi-stage through holes 17, which act as a blocking member to prevent the laundry a from moving forward without hindering the flow of suction air. By causing air (indicated by solid line arrows in the drawing) to flow into the bypass pipe 10b through the through hole 17 of the basket 16, which is a blocking member of the hopper 7, the branch pipe 6
The speed of the laundry a, which has been suctioned and conveyed from the basket 16, is lowered in the basket 16, which is a blocking member that prevents the laundry a from moving forward, and the laundry is dropped and stored.

Therefore, in order to suction and transport the laundry a into the hopper 7,
When the switching valve 4 of a predetermined hopper 7 with the opening/closing lid 8 closed is operated to open the corresponding branch pipe 6 side, and the lid 3 of the input port 2 is opened and the blower 12 is activated, the suction air flows as shown by the solid line in Figure 1. As shown by the arrow, from the input port 2 through the pneumatic pipe 1 to the designated hopper 7.
The air is sucked into the air, and further flows from the bypass pipe 10 of the predetermined hopper 7 to the intake pipe 11.

The flow of this suction air moves the laundry a to the designated hopper 7.
However, in this case, the switching valves of the hoppers other than the hopper that stores laundry a are closed on the branch pipe side, and
The input ports other than the input port 2 into which the laundry a is dropped are also closed, and simply by operating the switching valve 4 of the hopper 7 and opening the branch pipe 6 side, the laundry is placed in the designated hopper. The laundry can be conveyed by suction, and by closing the valve 14 of the bypass pipe 10 of the hopper 7 with the opening/closing lid 8 open, the suction conveyance to other hoppers 7 can be continued.

According to the present invention configured as described above, laundry can not only be air-transported to a designated hopper by simply operating the switching valve of each hopper, but also the flow of suction air within the hopper can be carried out without being obstructed. The laundry to be conveyed can be reliably dropped into the hopper and stored in the hopper without obstructing the flow of suction air by the blocking member that prevents the object from moving forward.

In addition, by providing a valve in the bypass pipe, the laundry in the hopper can be easily taken out by opening the opening/closing lid of the hopper after closing the valve and blocking the bypass pipe, and the laundry inside the hopper can be easily taken out from the lower end of the opened hopper. This system does not draw outside air into the intake pipe through the bypass pipe, allowing continuous suction and conveyance without reducing the air suction power to other hoppers, and the blower is activated each time laundry is taken out. No need to stop.

Furthermore, the overall structure of the equipment is simple, its handling is simple, and the equipment occupies less space, making it possible to plan the work management system in the factory and save labor. .
