Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container empty feeding device in a sealing device that seals a container such as a bottle by molding a cap or the like on the mouth of the container.

In the cloud filling process, as shown in the first diagram, the bottle 1 is sent to a depalletizer 2, taken out by an uncaser 3, sent to a dust washer 4 for cleaning, and filled with the contents in the bottle 1 by a filling machine 5. is sent to the sealing device 6 to form and seal the capping material 7 on the mouth of the bottle 1 as described above,
Next, it is packed in a case 8 and sent out from a palletizer 9.

However, when the day's work is finished, it is necessary to take out all the bottles 1 remaining in the dust washer 4 from the ink washer 4 and return them to the uncaser 3 from the viewpoint of hygiene. Conventionally, as shown by dotted lines 10 and 11 in FIG. I had set it back to 3. However, between the pupil washing machine 4 and the filling machine 5, and between the filling machine 5 and the sealing device 6, the path is made as short as possible to prevent dust and bacteria from entering. Since a dust cover etc. are provided, it is difficult to take out continuously by a conveyor. In particular, if the filling machine 5 and the sealing device 6 are directly connected, it is impossible to take out the bottle 1 from there. For this reason, a person must take out the bottles 1 one by one from the conveyor in front of the sealing device 6, about 200 to 300 bottles, which is a very difficult task. On the other hand, the head of the sealing device 6 is raised to empty the bottle 1, but this work not only requires a considerable amount of effort, but also causes the head to become misaligned when the machine is restarted. This was inconvenient because the adjustment easily went out of order. The present invention has been made in view of such circumstances, and provides a sealing device 6 that can automatically empty the bottle 1, that is, feed the bottle 1 so that the head does not come into contact with the bottle at all.

An embodiment of the present invention will be described in detail below with reference to the drawings.

As shown in FIG. 2A, a head 22 is provided to revolve on a main shaft 21 which is shielded at the center of a base 20 for transporting the bottle 1, and is also provided to rotate via a sun gear 23 and a planetary gear 24.

As shown in FIG. 3A, a double cylinder 25 is formed on the upper part of the head 22, and a roller 26 pivoted on the upper part of the double cylinder 25 engages with a grooved cam 27 fixed on the main shaft 21 and extending in an annular shape. do. Double pistons 28 and 29 are provided in this cylinder 25, and these pistons 28,
The upper part of a central shaft 31 that passes through the head 22 is screwed onto a shaft 30 fixed to the head 29, and a connector 32 is connected to the shaft 30 via a bolt 33. A compression spring 34 is provided below the upper piston 28 to force it upward. The chambers 35, 36 above the double pistons 28, 29 are connected to the shaft 30.
The port in FIG. 2 and the hand valve 39 shown in FIG.
A rod 41 for pressing the upper surface of the capping material 7 placed on the mouth of the bottle 1 is mounted on the lower end of the central shaft 31.
This twill 41 is springed downward by a spring 42. A pressure block 43 made of metal is screwed onto the lower end of the central shaft 31, and a presser plate 44 is also provided at the lower end of the block 43 so as to be resiliently movable downward by a spring 45. A cylindrical shaft 46 of the head 22 surrounding the central shaft 31
A ball bearing 47 and a bush 4 are installed in the connection 32.
The lever 49, 49, 49 as shown in FIG.
, 50, 50 should rotate in the horizontal plane, respectively.
At one end of the levers 49, 49, 49, shafts 53, 53, . 53, ... are springs 54, 54, .
It moves upwards due to...

An arm 49a is provided at the upper end of the shaft 50, and the arm 49a engages with a piston 56 of a cylinder 55 provided below the head 22 in the opposite direction as shown in FIG.
The inner chamber 57 of 5 has a through hole 58 and a central axis 31 of the head 22.
The hand is connected through a through hole 59 extending inside the head 22 and through a through hole 60 extending radially in all directions inside the head 22 through a valve 62 that opens and closes in conjunction with a timing cam 61 as shown in FIGS. 4 and 2. Valve 39 communicates with four air pressure sources.Next, the operation of this device will be explained.

When forming the capping material 7 on the mouth of a normal filled bottle 1, the hand valve 39 shown in the fourth figure is operated and opened, and the pressure of the air pressure source 40 is applied to the upper part of the double cylinder 25 through the through holes 38, 37. Introduced into chambers 35 and 36.

As a result, the pistons 28 and 29 are 120 to 320k9
The central shaft 31, cylinder shaft 46 connected thereto, levers 49, 49, . 46 is the sun gear 23
It revolves while rotating on its own axis due to meshing with the planetary gear 24. As the head 22 revolves, the roller 26 is moved up and down by the grooved cam 27, and the head 22 moves along a trajectory as shown in FIG.
When the rod 41 is lowered to the molding position as shown in
presses the center of the upper surface of the capping material 7, and the presser plate 44 of the pressure block 43 is brought into contact with the upper surface of the capping material 7. On the other hand, in this molding position, the valve 62 engages with the timing cam 61 and opens as shown in FIG. Inner chamber 5 of cylinder 55
7, the piston 56 and the arm 49a are actuated outwardly at the opening in FIG. 3, and the levers 49, 49...
The inner end of the capping material 7 moves inward in FIG. . When the bottle is to be passed through the sealing device 6 without covering it with the capping material 7 at the end of the work, the supply of caps is stopped and the hand valve 39 is closed.

As a result, the pistons 28 and 29 rise by about 9 degrees due to the elasticity of the spring 34, and the central shaft 31, which is continuous with the pistons 28 and 29,
Cylindrical shaft 46 and levers 49, 49, . . . supported thereon.
- Since the thread roller 51, skirt roller 52, etc. are in the upper position, even if the head 22 is lowered by the groove cam 27, the rod 41 is inserted into the mouth of the bottle 1, and the pressure block 43 is not inserted into the mouth of the bottle at all. Even if there is no contact and the valve 62 is opened by the timing cam 61, the cylinder 55
No air pressure is introduced into the thread roller 51 .
, the forming rollers such as the skirt loaf 52 do not come into contact with the mouth of the bottle. Therefore, the bottle 1 is safely passed through the sealing device 6 and comes out, so that the bottle can be automatically and continuously returned to the encaser 3 by the bypass conveyor as shown by the line 12 in FIG. . As described above, in the present invention, the central axis of the head and the cylindrical shaft that supports the forming roller are elastically pushed upward by the spring, so by releasing the pressure in the sealing, the piston, the central axis, and the cylindrical shaft move upward. Since it can be operated, the bottles can be automatically emptied into the sealing system, and therefore can be continuously returned to the casing via the bypass conveyor from the exit of the sealing system, or can be flowed to the casing and then returned to the casing. It is possible to save a lot of labor, and the device can be restored by applying pressure, so there is no need for readjustment.

In the above embodiment, the piston 28 is connected to the compression spring 34.
However, instead of this, a tension spring stretched between the cylinder 25 and the connecting pipe 32 may be used to make the spring spring upward. Also, the piston 28 is connected to the spring 34.
Alternatively, it may be elastically released above an electromagnetic device such as a solenoid.

Further, in the above embodiment, the head is supported by a cylinder, and the cylindrical shaft supporting the forming roller is connected to the piston, but instead, as shown in the sixth figure, the head 22a is supported by a piston 28a, and the head 22a is connected to the cylinder 25a. A cylindrical shaft 46a supporting the forming roller may be connected. It is obvious that the cylinder and the piston have the same effect, and it can be easily implemented within the spirit of the present invention, and it is natural that the invention is included in the scope of the claims even if the cylinder and the piston are reversed. .
