[Industrial application field]

This invention enables the use of large numbers of sheets, such as when supplying paper to paper box making machines and printing machines. A sheet used when stacking layers and removing them one by one from the top by vacuum suction. Relating to a body adsorption device.

0002

[Conventional technology]

Compatible with changes in the size and shape of the sheet used in the sheet suction device In order to Conventionally, there was a device in which only a part of the mouthpiece was selected and used. It is being This adsorption device has a complicated structure, is expensive, and is prone to failure. It has the disadvantage of being small.

0003

[Problem that the idea aims to solve]

Therefore, the present invention achieves the same effect as this conventional adsorption device with a simpler configuration. It is intended to represent.

0004

[Means to solve the problem]

The present invention includes a pipe connected to a suction pump and located on a stacked sheet body; This pipe has a number of suction holes formed at intervals, and a suction hole that fits into the pipe. A suction tube covers each hole and is movable longitudinally or circumferentially along the pipe. a mouthpiece holder, and a mouthpiece holder formed on the mouthpiece holder to communicate with the suction hole. a through hole that can be opened, a suction port that is connected to this through hole and that attracts the sheet body, and It is formed on the outer periphery of the suction hole, and is located at a position where the suction hole and through hole are communicated by moving the suction mouth holder. It is a sheet suction device that has a stopper that stops it in a position that closes the suction hole and the suction hole. be.

[0005]

【Example】 Hereinafter, embodiments illustrating the present invention will be described in detail.

[0006] In this adsorption device 10, the pipe 11 is a sheet in which a plurality of pipes are stacked in parallel. provided on the body 12 (only one is shown) and connected to the suction pump 13, respectively. has been done. This pipe 11 moves vertically and horizontally to cover the sheet body 13 one piece from above. It constitutes a part of the supply device that takes out the parts one by one.

[0007] This pipe 11 is made of a round pipe, its tip is closed with a cap 14, and its middle is closed with a cap 14. A large number of mouthpieces 15 are provided at intervals between them.

[0008] Each mouthpiece 15 has a configuration shown in FIGS. 2 to 5. On the bottom of pipe 11 A suction hole 16 is formed around which a mouthpiece holder 17 is fitted. This sucking The mouth holder 17 is made of a short pipe, and has an O-ring 18 in contact with the pipe 11 inside. a, 18b, 18c, between the O-rings 18a, 18b or between the O-rings 18b, The suction hole 16 can be covered between 18c, and the suction hole 16 can be covered in the longitudinal direction and circumferential direction along the pipe It is possible to move in the direction. This mouthpiece holder 17 has O-rings 18b, 18 A through hole 19 that can communicate with the suction hole 16 is formed between the A suction port 20 having a substantially conical shape and having a peripheral end made of rubber is provided outside the through hole 19. There is.

[0009] Stoppers 21a and 21b made of small screws are provided on the top surface of the pipe 11, and One end of the mouthpiece holder 17 is placed on the topper 21a, and the topper 21a is formed at this end. When engaged with the groove 22, the suction hole 16 and the through hole 19 communicate with each other, and the stopper 21b When the other end of the mouthpiece holder 17 is placed here, the suction hole 16 is aligned with the O-ring 18. It is arranged so that it is located between a and 18b and is closed.

0010 This adsorption device 10 is used in the following manner. Shape and size of sheet body 13 Accordingly, move the mouthpiece holder 17 of each mouthpiece part 15 and place the sheet body 13 on the suction For the suction port 15 to be attached, engage the stopper 21a and the groove 22, and For the mouth part 15, the mouthpiece holder 17 is placed against the stopper 21b. thus When the supply device is operated, only the desired suction port 20 is operated and the sheet body 13 is sucked. be able to. Note that for the mouthpiece 15 that is not activated, the mouthpiece holder 17 It is also possible to rotate the mouthpiece 20 so that the mouthpiece 20 faces upward.

[0011] In the above embodiment, the mouthpiece is operated by moving the mouthpiece holder in the longitudinal direction of the pipe. , I am trying to switch between inactivation and inactivation, but I am trying to switch by moving in the circumferential direction. Needless to say, such a configuration is also possible.

0012

[Effect of the idea]

As mentioned above, the suction device of the present invention moves the suction mouthpiece to the suction mouthpiece. A state in which the suction port is activated by communicating with the suction hole, and a state in which the suction port is not activated by blocking the suction hole. The suction port holder also functions as a valve for the suction hole. be. Therefore, the structure is simpler, cheaper, and less likely to break down. Become. Furthermore, there is an operation to select the mouthpiece to be used depending on the shape and size of the sheet body. is easy and convenient to use.

FIG. 2 is a sectional view of the mouthpiece of the same example in a state where the mouthpiece is activated.

FIG. 3 is a sectional view of the mouthpiece portion of the same example in a state where the mouthpiece is not activated.
