Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention, when pneumatically transporting a jug, evacuates the jug, checks whether the degree of vacuum is good or bad, and sends a normal product to a pneumatic tube for transferring the jug, and The present invention relates to a jug supply station in an air transfer facility that sends good products to a waste pipe.

[Prior art]

In a conventional supply station of this type, a rotary body is rotated in a casing to which a jug and a cartridge transfer air feeding pipe are connected, as well as an opening for receiving a jug and a cartridge. The rotary body is provided with two holding portions for holding the jug and the cartridge, and the rotary body is rotated by a predetermined angle to perform work on the jug and the cartridge at each rotation stop position. The invention of JP-A-61-55021 relates to a jug cartridge supplying station in an air conveying system configured to be carried out in the above.

However, in the above-mentioned supply station, since the rotating body is structured to rotate in the vertical plane, the jug is evacuated, and as a result of checking the quality of the vacuum, the jug having a poor vacuum is discarded from the casing. A mechanism to push out laterally is required, and a vacuum defective jug disposal device is installed separately. For this reason, the main body of the jug supply station becomes large, and the rotating body rotates in the vertical plane, so that the defective vacuum jag cannot be discarded to the outside of the jug supply station when the defective vacuum jag disposal device fails. There was a flaw.

In addition, each operation for the jug, that is, sending out the jug to the jug supply station, vacuuming the jug, checking the completion of vacuuming the jug, discarding the defective vacuum jug, and conveying air to the outside of the jug supply station for the vacuum completed jug. However, there is a drawback that the above process cannot be continuously and fully automated.

[Object of the Invention]

The present invention has been made in order to solve the above-mentioned conventional drawbacks, and is small and compact, does not occupy a large installation space, and the defective vacuum jug is discarded without the defective vacuum jug discarding device. It is intended to provide an easy jug supply station.

[Structure of Invention]

In order to achieve the above object, a jug supply station of the present invention is provided with a jug holding portion and delivers a jug receiving port and a jug whose inside is depressurized to an upper surface of a casing containing a rotor rotating in a horizontal plane. A jug vacuum device that connects a jug outlet and connects a jack waste pipe for discarding a vacuum-deficient jug to the lower surface of the casing, further includes a jug vacuum device that is located below the casing to depressurize the inside of the jug, and It is characterized in that the rotor is intermittently rotated in the order of the jug receiving port, the jug vacuum device, the jug outlet, and the defective vacuum jug discard pipe. The jug is evacuated and as a result of the vacuum degree check, the defective vacuum jug rotates to the position of the defective vacuum jug discard pipe of the rotating body and stops, then it falls by its own weight and is discarded outside the jug supply station. At that time, there is no need for a vacuum defective jug discarding device as in the conventional case, and since the rotating body rotates in a horizontal plane, its drive motor can be directly connected to the rotating shaft of the rotating body, thus making the entire device compact. , Does not take up any installation space.

On the other hand, the evacuated jug automatically reaches the position of the air tube for transferring the jug by stopping the rotation of the rotating body, and the jug is pneumatically conveyed, but it is easy to automate these series of operations. Done.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.
1 is a front sectional view of a jug supply station according to an embodiment of the present invention, FIG. 2 is a side view of FIG. 1, and FIG. 3 is a plan view of FIG.

First, the casing 1 of this jug supply station is provided with a receiving port 4 for receiving the jug 8, while a rotor 2 as a rotating body is rotatably arranged in a horizontal plane in the casing 1. A jug holding portion 3 is provided on the peripheral surface of 2 in parallel with the rotation axis.

The jug holding portion 3 holds the jug 8 and transfers the jug 8 by being rotated by a rotary shaft to which a reversible motor 10 is attached via a torque limiter 9.

In addition, a jug transfer pneumatic tube (not shown) is connected to the casing 1 in which the receiving port 4 for receiving the jug 8 is opened.

Further, in the rotor 2, the jug holding portion 3 corresponds to the receiving port 4, the jug holding portion 3 draws a vacuum in the jug 8 as indicated by 5, and the jug holding portion 3 discards the jag 8 having a poor vacuum. 7, the jug holding portion 3 is rotated so as to stop the jug 8 which has completed the evacuation to a jug transfer pneumatic tube (not shown). It is arranged to perform work.

The rotor 2 is rotated by a predetermined angle by a reversible motor 10 or an appropriate motor, and the rotation stop position of the rotor 2 is detected by a limit switch (not shown), and the position of the jug holding portion 3 is thereby detected. I can know.

Reference numerals 11 and 12 in FIG. 3 are sensors for detecting that the jug 8 has fallen into the receiving port 4 and that the jug 8 has been pneumatically conveyed from the delivery port 6, and 13 in FIG. 1 is shown. A jug vacuum device connected to a vacuum pump, in which a needle 14 is inserted into the jug 8 and the inside of the jug 8 is evacuated by the vacuum pump.

Next, when a detector (not shown) detects that the degree of vacuum does not reach the predetermined degree of vacuum within a certain time, the jug 8 is determined to be defective in vacuum, but is determined to be defective in vacuum. The jug 8 is thrown out of the casing 1 by its own weight through the defective vacuum jug discard pipe 15 and discarded.

Next, the operation of the above-described jug supply station of the present invention will be described. The jug 8 is dropped from the receiving port 4 to the jug holding portion 3, and at this time, the sensor 11 detects the fall to the jug holding portion 3 and a signal is output. Is emitted.

The rotor 2 holding the jug 8 is reversible motor 10
The rotation of the jug 8 is stopped at the position indicated by 5 corresponding to the vacuum evacuation of the jug 8.

When a limit switch (not shown) detects that the rotor 2 has stopped at this position, the jug vacuum device 13 operates and the inside of the jug 8 is evacuated.

When it is detected by a detector (not shown) that the vacuuming operation is normally completed, a normal completion detection signal is sent to the reversible motor 10, and the motor 2 causes the jug 8 to carry a jug transfer gas. It rotates to the position indicated by 6 corresponding to the pipe and stops.

When a limit switch (not shown) detects that the rotor 2 has stopped at this position, the jug 8 is pneumatically conveyed in the air pipe for jug transfer (not shown).
The rotor 2 rotates to the receiving port 4 of the jug 8 and stands by.

On the other hand, when it is detected that the evacuation work is abnormally terminated, an abnormality detection signal is sent to the reversible motor 10, the rotor 2 is rotated to the vacuum defective jug discarding position 7, and is stopped when the limit switch detects it.

At this position, the defective vacuum jug 8 is discarded to the outside of the casing 1 through the defective vacuum jug discard pipe 15 by its own weight.

When this is completed, the reversible motor 10 rotates the rotor 2 to the position where the jug holding portion 3 corresponds to the receiving port 4, and enters the standby state.

Thereafter, the same operation as described above is repeated, but in this way, each operation is continuously and automatically performed.

〔The invention's effect〕

As described above, according to the present invention, the jug supply station itself is vertical, and the jug receiving port 4 and the jug sending port 6 are arranged above the casing 1 in which the rotor 2 rotating in the horizontal plane is incorporated, while the casing 1 Since the defective vacuum jug waste pipe 15 and the jug vacuum device 13 are provided under the jug, the jug supply station itself can be made compact, and
Since it does not take up any installation space, the installation area of the jug supply station can be greatly reduced compared to the conventional one.

Further, according to the present invention, since the rotor 2 having the jug holding portion 3 is rotated in the horizontal plane, the jug discarding device for ejecting the defective vacuum jug from the jug holding portion 3 of the rotor 2 is not used. It can be dropped and discarded by its own weight, and power consumption can be reduced accordingly.

In addition, the present invention has an advantage that the reception of a jug, the evacuation of the jug, the conveyance of the evacuated jug, the discarding of the defective vacuum jug, etc. can be performed automatically.
