DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary filler bowl for a filling machine used in a bottling system, and more particularly to an improved technique for joining a filler bowl body and a lid body.

[0002]

BACKGROUND ART Rotary filler bowl of this type, in the normal charging operation, since the filler bowl body portion is filled while rotating filling valve device or the like and the co-between filler bowl body and its lid It was necessary to have a joining structure that could relatively rotate. At the same time, when performing the cleaning or sterilizing operation of the filler bowl, the filling valve device, and the like, the filler bowl main body and the lid had to be hermetically sealed. For this reason, the filler bowl and the lid are generally joined via rotatable sealing means such as a rotary joint. However,
In the case of this technical means, since a sliding portion such as a rotary joint is exposed to a washing or sterilizing zone during a washing or sterilizing operation, there is a problem that dust and a processing agent easily remain. For this reason, during a normal filling operation, the filler bowl and the lid are separated from each other and the operation is performed in an open state.On the other hand, during a cleaning or sterilization operation, the both are tightened using a fastener such as a clamp or a bolt. A structure that operates in a closed state has been adopted.

[0003]

However, even if the latter structure is adopted, the problem of the residue of dust and treatment agent is eliminated, but the tightening of clamps, bolts, etc. in cleaning and disinfecting operations is performed one by one. There was the inconvenience of having to seal with a tool. In addition, the automation of the sealing operation requires a complicated apparatus itself, which is not practical. In view of such circumstances, an object of the present invention is to switch between the above two operation modes, in which there are few problems such as the above-mentioned residue of the dirt and the processing agent, and further, there is no need to perform a tightening operation with a fastener such as a clamp or a bolt. An object of the present invention is to provide a rotary filler bowl in a filling machine which is also suitable for automation of work.

[0004]

According to the present invention, in order to solve the above-mentioned problems, according to the first aspect of the present invention, a filler bowl main body and a lid disposed so as to be vertically movable with respect to the filler bowl main body. in the rotary filler bowl consisting of, the upper rim portion projecting horizontally on top of the filler bowl body together when continuously provided, consecutively provided a lower peripheral edge which polymerize below the upper peripheral edge on the lid , Philabo
Before the lid is raised by the internal pressure acting inside the
The joined state between the upper peripheral portion and the lower peripheral portion is urged.
In the invention according to the second aspect, a sealing member is provided on one of the overlapping portions of the lower surface of the upper peripheral portion and the upper surface of the lower peripheral portion. The technical means of adding the In the invention of claim 3, wherein the said upper peripheral edge and the lower circumferential edge portion together when joined through the lip-shaped sealing member, is curved free end of the sealing member to the filler bowl interior side The technical means of mounting in a state where it was placed was adopted.

[0005]

By employing the above technical means, during a normal filling operation, the rotary operation can be performed without any trouble in a state where the filler bowl body and the lid are separated from each other or in a state where the filler bowl body is closed through the lip-shaped sealing member. At the same time, during the cleaning or sterilizing operation, the inner pressure based on the processing fluid itself such as sterilizing steam supplied into the filler bowl causes the upper peripheral edge lower surface of the filler bowl main body and the lid in the raised state of the lid body to be in contact with each other. Since the free end of the lip-shaped seal member mounted in a curved state on the joint surface with the upper surface of the lower peripheral portion of the body or the inside of the filler bowl chamber is urged to the side in which the lip-shaped seal member is more intimately contacted, especially a clamp, a bolt, It is possible to obtain an accurate sealed state without tightening using
It is, when the switching operations of said operating configuration is greatly simplified
To together, it is extremely effective for the automation.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view showing a main part of one embodiment of the present invention. In the figure, reference numeral 1 denotes a filler bowl main body, which is composed of an upper main body 2, a lower main body 3, and a cylindrical main body 4 connected between them in a liquid-tight manner. An upper peripheral portion 5 is connected to the upper portion of the filler bowl body 1 so as to protrude partly in the horizontal direction. In the lower portion of the filler bowl 1, a required number of outlets 6 connected to respective filling valve devices (not shown) for supplying a filling liquid are formed. Reference numerals 7 and 8 are fixing bolts. In the figure, reference numeral 9 denotes a lid, which is provided so as to be able to move up and down with respect to the filler bowl body 1 by means of a lifting means using a manual or electric motor (not shown) mounted on the lid 9. A lower peripheral portion 10 is connected to the lower portion of the lid 9 so that a part of the lower peripheral portion 10 projects horizontally, and the lower peripheral portion 10 is overlapped so that the upper surface thereof faces the lower surface of the upper peripheral portion 5 of the filler bowl 1. I
It is arranged in the state where it was. Reference numeral 11 denotes a seal member provided on the upper surface of the lower peripheral portion 10. Furthermore, the filling liquid pipe 12 in the cover 9 is integrally provided, in together when used as a filling liquid flows, during the cleaning or sterilizing operation is also used also as a treatment fluid inflow.
Incidentally, 13 is also the level sensor for the mounted liquid level adjustment on the cover 9.

However, during a normal filling operation,
The lid 9 is in a lowered state, and the lower peripheral portion 10 of the lid 9 and the lower surface of the upper peripheral portion 5 of the filler bowl main body 1 are lower.
It is in a state of being separated from the seal member 11 attached to the upper surface. Therefore, there is no problem in rotating the filler bowl main body 1 with respect to the lid 9. In this state, the filling operation is performed. As is well known, the filling liquid flows into the rotating filler bowl body 1 through the filling liquid pipe 12, where the liquid level is adjusted based on the detection result of the level sensor 13. After that, the liquid is supplied to each filling valve device (not shown) through the outlet 6, and each container is filled with the filling liquid while rotating.

Next, when performing a washing or sterilizing operation, the lid 9 is raised through the elevating means (not shown) mounted on the lid 9, and the upper portion of the filler bowl body 1 being stopped is stopped. Lower surface of peripheral portion 5 and lower peripheral portion 10 of lid 9
The inside of the filler bowl is sealed by bringing the seal member 11 attached to the upper surface into contact with the sealing member 11, and in this sealed state, the processing fluid such as sterilizing steam flows through the filling liquid pipe 12 to perform cleaning or cleaning. A sterilization operation is performed. In this case, by further adjusting such that a slight gap is formed between the lower surface of the upper peripheral portion 5 and the seal member 11, and adding a step of flowing out the sterilizing steam or the like from the gap. In addition, those contact portions can be further cleaned or sterilized.

FIG. 2 is a partial longitudinal sectional view showing another embodiment of the present invention. The embodiment shown in FIG. 2A is a seal member attached to a joint between the lower surface of the upper peripheral portion 5 of the filler bowl main body 1 and the upper surface of the lower peripheral portion 10 of the lid 9.
Those longitudinal sectional shape with a substantially triangular lip-like sealing member 14, rotates the filler bowl body 1 while also to lightly abut on the upper peripheral edge 5 the lower surface is a mating during charging operation Thus, the filling operation can be performed in a substantially closed state. At the time of the washing or sterilization operation, the operation is performed by slightly raising the lid 9 to make the contact state of the seal member 14 more reliable. In the embodiment (b) in the figure, a lip-shaped sealing member 15 having a substantially triangular cross section is used as the sealing member.
However, in both the filling operation and the washing or sterilizing operation, the free end thereof abuts on the upper surface of the lower peripheral portion 10 of the lid 9 which is the mating side, and is bent toward the interior of the filler bowl. It is characterized in that it is operated in a state where it is set.
That is, during the filling operation, the sealing member 15
When the free end of the filler bowl abuts on the upper surface of the lower peripheral portion 10 of the lid body 9 which is the mating side and is curved toward the inside of the filler bowl chamber, the filler bowl body 1 rotates while the above-described filling is performed. At the same time as the operation is performed, during the cleaning or sterilizing operation, the free end of the sealing member 15 is moved to the other side by the pressure action based on the processing fluid itself such as sterilizing steam supplied into the stopped filler bowl. it is strongly pressed to the lower peripheral edge portion 10 the upper surface of the cover 9 is, under the sealed state in which the contact state is further strengthened, in which the work is performed. Therefore, in the case of the present embodiment, both operations can be performed without any trouble without raising and lowering the lid 9 through the both operation modes. Needless to say, the specific shape of the filler bowl, the presence / absence of the seal member, the specific shape, the attached portion, and the like can be selected in design.

[0010]

According to the present invention, the following effects can be obtained based on the above constitution. (1) During a cleaning or sterilization operation, an inner pressure based on a processing fluid itself such as sterilizing steam supplied into the filler bowl causes an upper peripheral lower surface of the filler bowl main body and a lower peripheral edge of the lid to be closed. Since the free end of the lip-shaped seal member mounted in a state in which the joint surface with the upper surface or its free end is curved toward the interior of the filler bowl is urged to the side where the free end more closely adheres, particularly a clamp, a bolt, etc. An accurate sealed state can be obtained without tightening using the tightening tool. (2) Since tightening with clamps and bolts is unnecessary,
Since switching of the cleaning or sterilizing operation and normal charging operation need only be relatively lifting the filler bowl body and a lid, the together the switching operation is greatly simplified, the automation of the switching operations It is extremely effective in performing. (3) The joint between the filler bowl main body and the lid is merely provided with a seal member , so that not only is there less dirt and processing agent left than in the conventional example using a rotary joint, and the lid is also provided. Is adjusted up and down with respect to the filler bowl to slightly separate the seal member and the other side to form a small gap therebetween, and if the processing fluid such as sterilizing steam flows out from the small gap, the flow rate of the processing fluid is reduced. It is also possible to clean or sterilize the contact part more cleanly . (4) Since the configuration is simple, there are few troubles.
