BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switching valve for an air transport device, and more particularly to a switching valve for an envelope waste paper pneumatic transport device that sorts and collects waste paper in envelopes generated by a plurality of bag-making machines by paper quality. It is a thing.

[0002]

2. Description of the Related Art Envelopes can be roughly classified into three types: white envelopes, brown envelopes, and colored envelopes. By the way, in a bag-making machine for producing envelopes, roll paper is cut out and cut to produce envelopes, but waste paper is always produced at that time. Waste paper is collected and reused, but it is collected separately for each paper quality.

Waste paper produced by the bag-making machine is pneumatically conveyed through a relay cyclone and pressed and compressed by a waste paper packing machine to be packed.

[0004]

[Problems to be Solved by the Invention] By the way, when several to several tens of bag making machines are arranged in a factory, it is not decided which color of envelope is to be produced by each bag making machine. Depending on the color of the envelope produced by the bag machine, the operator must provide a switching valve that allows the waste paper to flow into the relay cyclone dedicated to that color.

In view of the above circumstances, the present invention discharges the stationary discharge body 2 having a plurality of discharge tubes 1 arranged in parallel on the same plane, and the vicinity of the upstream side of the discharge tube 1 of the stationary discharge body 2. Tube 1
Moving frame 3 that moves in a direction orthogonal to the pipeline of
Is attached to the discharge pipe 1 so as to be able to advance and retreat in the direction of the pipe line, is provided so as to be connectable to each of the plurality of discharge pipes 1 of the stationary discharge body 2, and has a tapered nozzle pipe 17 which is fitted in the discharge pipe 1.
And a switching tube 4 provided with a movable tube 3 and a tip end of the switching tube 4
And a switching lever 33 which is connected to the switching lever 4 to move the switching pipe 4 back and forth in the direction of the conduit of the discharge pipe 1.

[0006]

The operator moves the switching pipe of the moving frame to a position below the discharge pipe of the color to be introduced, and operates the switching lever to connect to the discharge pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The switching valve of the pneumatic transportation device of the present invention will be described in detail below by taking the switching valve of an envelope waste paper pneumatic transportation device as an example. FIG. 1 shows a schematic flow diagram of an envelope waste paper pneumatic transportation device. The waste paper generated in the bag making machine 51 is a suction fan 52 and a switching valve.
After passing through 53, it enters the relay cyclone 54 _W , 54 _B , 54 _C, and then through the suction blower 55 _W , 55 _B , 55 _C , the cyclone hopper 56 _W ,
It flows into 56 _B and 56 _C and is supplied to an automatic waste paper packing machine (baler) 58 via a steel conveyor 57. Reference numeral 59 is an exhaust chamber.

An operator manually switches the switching valve 53 according to the color of the envelope produced by the bag making machine 51, and supplies the waste paper to the relay cyclone 54. Usually, several to several tens of bag making machines 51 are connected to one relay cyclone 54. A plurality of the switching valves 53, three in this embodiment, are arranged in parallel on the same plane.
A stationary discharge body 2 provided with a discharge pipe 1 of a book, a moving frame 3 which moves below the stationary discharge body 2 along the stationary discharge body 2, and a stationary frame which is attached to the moving frame 3 so as to be able to move up and down. Each of the plurality of discharge pipes 1 of the discharge body 2 includes a switching pipe 4 which is provided so as to be connectable thereto. A pipe (not shown) is connected to the discharge pipe 1.

The stationary discharger 2 is provided with a roller so that the moving frame 3 can be moved downward. That is, the brackets 11 are hung at the four corners of the moving frame 3, the rollers 12 and 13 are arranged above and below the brackets 11, respectively, and the moving frame 3 is sandwiched between the rollers 12 and 13. Regulates the vertical movement of the. Further, a supporting piece 14 is horizontally provided on the bracket 11, and a roller 15 is provided on the supporting piece 14 to hold the moving frame 3 and regulate the lateral movement of the moving frame 3.

As described above, the moving frame 3 can move below the stationary discharge body 2 along the stationary discharge body 2. Further, stoppers 16 are provided at both ends of the moving frame 3 so that the switching pipe 4 of the moving frame 3 can be stopped below the discharge pipe 1 so as to come into contact with the bracket 11 and stop. A switching pipe 4 is attached to the moving frame 3 so as to be capable of advancing and retreating in the vertical direction so that it can be connected to each of the plurality of discharge pipes 1.

The switching tube 4 includes a nozzle tube 17 having a small diameter in the upper portion, which is fitted in the discharge tube 1 at the upper portion, an acrylic transparent tube 18 having an intermediate portion through which the inside can be seen, and a lower steel tube. 19
And consists of. Acrylic transparent tube 18 and nozzle tube 17 and steel tube
A packing 20 is interposed between the nozzle tube 17 and the nozzle tube 17
A connecting rod 23 is inserted into and connected to the outward flange 21 at the lower end and the outward flange 22 at the upper end of the steel pipe 19. Steel pipe
A pipe (not shown) is connected to the lower end of 19.

A guide rod 32 is hung from a support plate 31 of the moving frame 3 to insert the outward flanges 21 and 22 so that the switching pipe 4 can slide up and down, and a packing 30 is provided outside the upper end of the nozzle pipe 17.
To provide. A switching lever 33 is provided so that the switching pipe 4 can be moved up and down to be fitted in or removed from the discharge pipe 1. The switching lever 33 is provided so as to straddle the switching tube 4, and the upper portion of the side plate 34 of the switching lever 33 is pivotally attached to the hanging plate 35 which is hung from the support plate 31 of the moving frame 3 so as to face outward with the upper end of the side plate 34. It is connected to the flange 21 via a connecting piece 36.

The operator operates the switching lever 33 to connect the switching pipe 4 to the required discharge pipe 1 by moving the moving frame 3 to the position below the discharge pipe 1.

[0014]

As described above, according to the present invention, the stationary discharge body 2 provided with a plurality of discharge tubes 1 in parallel on the same plane, and the discharge pipe near the upstream side of the discharge tube 1 of the stationary discharge body 2. The moving frame 3 that moves in the direction orthogonal to the pipe line 1 and the discharge pipe 1 on the moving frame 3.
The stationary discharge body 2 is attached so as to be movable back and forth in the direction of the pipe
Of the plurality of discharge pipes 1, and a switching pipe 4 provided with a tapered nozzle pipe 17 that fits in the discharge pipe 1, and a tip of the switching pipe 4 pivotally attached to the moving frame 3. A switching lever that is connected to move the switching pipe 4 back and forth in the direction of the discharge pipe 1.
Since it is a switching valve of the air transportation device composed of 33, an operator can easily flow the waste paper into the relay cyclone dedicated to the color according to the color of the envelope manufactured by the bag making machine.
