It comprises a second charging cylinder 350 to reciprocate.

As shown in FIGS. 5A and 5B, the capping chuck 310 includes a hollow cylindrical body 311 in which a recess 311a is formed to adsorb a lid 103 at a tip end thereof. A central shaft 312 connected to the support member 320 through a bearing 312a so as to rotate the body 311 by a driving unit 330 and inserted into a center of the body 311; It is attached to the front end of the central axis 312 and the piston head 313 of a rubber material in close contact with the inner peripheral surface of the body 311, interposed between the inner peripheral surface of the body 311 and the central axis 312 Compression spring 314 and the clutch member 316 is fixed to the inside of the body 311 to selectively contact the pressing member 315 fixed to the central axis 312.

The body 311 has a suction hole 311b that connects the recess 311a at the front end and a hollow inner space. When the piston head 313 moves upward, a negative pressure is generated inside the body 311 so that external air is sucked in through the suction hole 312b. At this time, if the lid 103 is placed in the depression 311a, the lid 103 is adsorbed instead of being sucked in air, and as long as the piston head 313 is not moved downward, the lid 103 is adsorbed. Will also remain.

The piston head 313 is made of a rubber material, and the diameter of the upper surface is made larger than the diameter of the lower surface so that the piston head 313 can be more closely adhered to the inner circumferential surface of the body 311 when moved upward from the inside of the body 311.

One end of the compression spring 314 abuts against the pressing member 315 fixed to the central shaft 312, and the other end of the compression spring 314 is an end inside the body 311. It is supported against the jaw portion 311c.

The clutch member 316 serves as a friction pad, and is preferably made of a silicon material. The clutch member 316 has a disk shape in which a through hole is formed at a center thereof so that the central shaft 312 is inserted therethrough.

As shown in FIG. 5A, the compression spring 314 inside the capping chuck 310 is not compressed, that is, when no force is applied to the capping chuck 310 from the outside. The pressing member 315 which is fixed and supports the compression spring 314 is pressed by the compression spring 314 to be in close contact with the clutch member 316. Therefore, when the central axis 312 rotates, the body 311 of the capping chuck also rotates.

However, as shown in FIG. 5B, the compression spring 314 inside the capping chuck 310 is compressed, that is, the capping chuck 310 is urged upwards (in the direction of the supporting member) from the outside of the capping chuck 310. In the state that the acting force, the central axis 312 is still and the body 311 is raised upwards. As a result, the pressing member 315 fixed to the central axis 312 also does not move, whereas the clutch member 316 fixed to the body 311 is moved upward with the body, and the pressing member 315 and The clutch members 316 are spaced apart from each other. Therefore, even when the central axis 312 rotates, the body 311 of the capping chuck does not receive the rotational force.

The drive unit 330 may include a motor 331 and a reducer 332 installed on the support member 320, a rotating shaft 333 rotated through the motor 331 and the reducer 332, and the rotating shaft ( And a bevel gear 334 that transmits rotational force to the central axis 312 of the capping chuck while rotating with the 333. The bevel gear 334 is provided by the number of mounting of the capping chuck 310 used in the capping device of the present invention.

Preferably, the first and second capping cylinders 340 and 350 are pneumatic cylinders. As will be described later, the cap 103 is covered by the first and second capping cylinders 340 and 350 and the motor 331.

The capping device 300 according to the present invention may further include a container pressurizing unit 360 for pressing and holding the container 101 in order to prevent shaking of the container when the lid 103 is covered with the container 101. have. The container pressurizing unit 360 is interlocked with the operation of the capping chuck 310 to press the container 101 when the capping chuck 310 is lowered to cover the container 103 with the cap 103. Any mechanism may be utilized as long as it can be secured to, for example, a pneumatic cylinder or the like can be employed.

Although two capping chucks are shown attached in the figure, in this embodiment, a total of five capping chucks are designed to be used. However, the number of capping chucks and the like does not limit the present invention.

In addition, the non-explained member number 340a shown in FIG. 2 indicates a guide rod for guiding the linear movement when the support member 320 is moved by the first capping cylinder 340, and FIGS. 3A to 4. The non-explained member number 350a shown indicates a guide rod for guiding the linear movement when the support member 320 is moved by the second capping cylinder 350.

Hereinafter, the operation of the capping device according to the present invention made as described above.

As shown by the solid line in FIG. 3A, when the capping device 300 according to the present invention is in the initial first position, the capping chuck 310 is maintained in the raised position by the first capping cylinder 340. At the same time it is held in the rear position by the second capping cylinder 350. In addition, at this time, the motor 311 which drives the capping chuck 310 to rotate is maintained.

When the capping device according to the present invention starts to operate, the first capping cylinder 340 is lowered to the lowered position the capping chuck 310 is moved to the second position shown by the dotted line in Figure 3a, wherein the capping The lid 103 supplied from the lid supply device 400 is positioned in the recess 311a formed at the tip of the chuck 310.

Since the first capping cylinder 340 is set in advance so as not to stop the operation even after the cap 103 is positioned in the recess 311a of the capping chuck 310, the capping chuck 310 is cap 103. ), The support member 320 on which the capping chuck 310 is supported continues to descend even though the capping chuck 310 is not moved. Accordingly, the central axis 312 inside the capping chuck connected to the support member 320 is lowered while compressing the compression spring 314, so that the capping chuck is in the state shown in FIG. 5B.

The first capping cylinder 340 in which the lowering operation is completed by a predetermined distance starts the lifting operation again to raise the support member 320. At this time, the central shaft 312 connected to the support member 320 is raised, but the capping chuck 310 is not raised by the compression spring 314 and is in contact with the lid 103. Subsequently, when the support member 320 is raised and the compression spring 314 is fully extended, the capping chuck 310 returns to the first first position as shown by the dotted line in FIG. 3B. However, the capping chuck 310 is attached to the recess 311a at the tip of the capping chuck 310 due to the negative pressure generated while the piston head 313 is raised together with the central axis 312. Is raised.

Subsequently, as shown in dashed lines in FIG. 3B and in solid lines in FIG. 3C, the second capping cylinder 350 operates to advance the support member 320 so that the capping chuck 310 is in a third position. Is advanced. At this time, the lid 103 is still adsorbed to the recess 311a at the tip of the capping chuck 310. When the capping chuck 310 is moved to the third position, the motor 331 mounted on the support member 320 is operated to rotate the capping chuck 310.

Subsequently, as shown by the dotted lines in FIG. 3C, the first capping cylinder 340 lowers the rotating capping chuck 310 and moves it to the fourth position, at the time just below the capping chuck 310. The container 101 filled with the liquid is transferred from the filling apparatus 200 to stand by.

The lid 103 adsorbed to the depression 311a at the tip of the capping chuck 310 which is rotated and lowered is lowered while being rotated together with the capping chuck 310, and the lid 103 is brought into contact with the container 101. It is screwed onto the vessel and covered.

Even if the cap 103 is in contact with the container 101 and the capping chuck 310 is no longer lowered, the supporting member 320 on which the capping chuck 310 is supported continues to descend. Accordingly, the central axis 312 inside the capping chuck connected to the support member 320 is lowered while compressing the compression spring 314. However, the lowering at this time is different from when the lid 103 is adsorbed, the pressing member 315 fixed to the central axis 312 of the capping chuck is separated from the clutch member 316 fixed to the body 311 of the capping chuck. It's only as good as it can be.

When the central shaft 312 inside the capping chuck connected to the support member 320 descends while compressing the compression spring 314, the pressing member 315 is separated from the clutch member 316 and at the same time. The piston head 313 fixed to 312 is lowered.

When the pressing member 315 is separated from the clutch member 316, the rotational force from the motor 331 is no longer transmitted to the body 311, and when the piston head 313 is lowered, the lid ( The negative pressure adsorbing 103 is released. As a result, the capping chuck 310 and the lid 103 are separated from each other.

At this time, even if the pressing member 315 is separated from the clutch member 316, the body 311 and the cap 103 of the capping chuck continue to rotate by inertia, and when the cap is completely coupled to the container 101, the lid Will stop rotating.

Subsequently, as shown by a dotted line in FIG. 3C, when the capping chuck 310 is lowered and moved to the fourth position by the first capping cylinder 340, the operation of the motor 331 is stopped, and then the The capping chuck 310 is raised by the first capping cylinder 340 and then reversed by the second capping cylinder 350 to return to the first first position. By repeatedly performing the above-described operation, the lid 103 is covered on the container 101 is repeatedly performed.

As described above, according to the present invention, there is provided a capping device for an automatic filling and capping device, which makes it possible to miniaturize the device by embedding a source of vacuum in the chuck.

In addition, according to the capping device of the present invention, since a separate vacuum generating pump and motor, etc. are not used, the cost and time according to the manufacturing are reduced.

In addition, according to the capping device of the present invention, the clutch member provided inside the capping chuck body does not need to stop the rotating pressure member forcibly even when it is in contact with the pressure member fixed to the central shaft. No wear reduces the cost and time required to maintain the capping chuck.
