Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rinser for cleaning a container such as a bottle conveyed by a holder while moving the cleaning liquid spray nozzle.

[0002]

2. Description of the Related Art A conventional rinser will be described with reference to FIGS. In FIG. 6, a container 1 such as a bottle is held in an inside of a holder 2 at a predetermined interval in the carrying direction, and the preliminary cleaning section A is moved as the holder 2 moves in the arrow direction. Is conveyed to the main cleaning section B at a constant speed V in the arrow direction.

The main cleaning section B is for injecting a high-temperature cleaning liquid from the cleaning nozzle 4 into the container 1 carried by the holder 2 and especially for completely cleaning the inside of the container 1, and this main cleaning is performed. In the section B, a moving frame 3 is provided below the container 1 so as to be reciprocally movable along the moving direction thereof, and a plurality of main cleaning nozzles 4 are provided on the upper surface of the moving frame 3 so as to match the intervals of the containers 1. ing.

One end of a drive rod 5 is pivotally connected to the moving frame 3, and the other end of the drive rod 5 is pivotally connected to one end of a swing arm 7 which is swingable about a support shaft 6. is doing. A cam follower 8 attached to the other end of the swing arm 7 is engaged with a cam groove 9a formed in the end surface of a disc cam 9, and the disc cam 9 is driven by a drive shaft 10 in synchronization with the movement of the holder 2. By rotating at a constant speed, the movable frame 3 can be reciprocated in synchronization with the movement of the container 1.

In the pre-cleaning section A, a pre-cleaning liquid having a predetermined temperature is sprayed on the container 1 carried by the holder 2 to pre-clean the inside and outside of the container 1 and at the same time.
To preheat in preparation for cleaning with a high-temperature cleaning liquid in the next main cleaning section B, and also in this preliminary cleaning section A, the moving frame 15 is provided below the holder 2 along the conveying direction of the container 1. A plurality of preliminary cleaning nozzles 16 are provided on the upper surface of the movable frame 15 so as to be reciprocally movable so as to match the intervals of the container 1.

For example, the moving frame 3 of the main cleaning section B advances so that the moving frame 15 of the preliminary cleaning section A operates in the opposite directions to the moving frame 3 of the main cleaning section B via the connecting means 17. When the cleaning is performed, the moving frame 15 of the preliminary cleaning section A is moved backward so that the moving frame 15 moves backward. The connecting means 17 has the above-mentioned 2
A swing arm 19 which is arranged between the two moving frames 3 and 15 and which can swing around the support shaft 18, and one end which is horizontally arranged and is pivotally connected to the moving frame 3 in the main cleaning section B. , A connecting rod 20 having the other end pivotally connected to one end of the swing arm 19.
Further, the connecting rod 2 is disposed in parallel with the connecting rod 20 and has one end pivotally connected to the moving frame 15 of the preliminary cleaning section A and the other end pivotally connected to the other end of the swing arm 19.
1 and. In the present embodiment, the distance l ₁ between the connecting rod 20 and the support shaft 18, the ratio between the distance l ₂ between the support shaft 18 and the connecting rod 21 is Yes set to be 2: 1, the coupling When the rod 20 reciprocates, the connecting rod 21 is reciprocally moved in the opposite direction through the swing arm 19, and at the same time, the reciprocating stroke amount and speed of the connecting rod 21 and the moving frame 15 change the connecting rod 20 and the moving frame. It is set to 1/2 of that of 3.

Next, the moving frames 3 and 15 are adapted to make one reciprocating motion by one rotation of the disc cam 9, and at that time, a required operation can be given to each moving frame 3 and 15. Thus, the cam groove 9a of the disc cam 9 is set to a required cam curve.

FIG. 7 shows the relationship between the rotational angle position of the disk cam 9 and the moving position of the moving frame 3, and thus the moving position of the main cleaning nozzle 4, in the main cleaning section B. Is moved forward from the retracted position at the same speed V as the transport speed V of the container as the disc cam 9 rotates at a constant speed. At this time, the main cleaning nozzle 4 provided on the moving frame 3 is moved forward while following the container 1 while being positioned at the center of the mouth of the container 1 in the inverted state.

When the movable frame 3 reaches the forward end position, the movable frame 3 is retracted at a high speed to the retracted end position. In the illustrated example, the movable frame 3 follows the container and moves forward. The ratio of the time of the process to the time of the return process in which the moving frame 3 returns from the forward end position to the backward end position is about 7/3. In this way, in the main cleaning section B, the time of the following process is set longer than the time of the returning process, and the main cleaning nozzle 4 remains in the container 1 in the center of the mouth of the container 1 in the following process. Since the container 1 is followed and moved forward, the inside of the container 1 can be sufficiently washed.

FIG. 8 shows the relationship between the rotational angle position of the disc cam 9 and the moving position of the moving frame 15, that is, the moving position of the preliminary cleaning nozzle 16 in the preliminary cleaning section A. As described above, since the moving frame 15 has an opposite action to the moving frame 3, when the moving frame 3 is moved forward from the retracted end position as the disc cam 9 rotates, the movable frame 15 moves to the retracted end position. From then on, the vehicle moves backward toward the forward end position at a constant speed.

Then, the preliminary cleaning nozzle 16 provided on the moving frame 15 is moved so as to cross the container 1 conveyed above from the front side to the rear side, so that the outside and inside of the container 1 are cleaned. Will be done. At this time, since the moving frame 15 is retracted at a speed slower than the forward movement of the moving frame 15, the preliminary cleaning nozzle 16 is moved from the front of the container 1 to the container 1 as compared with the case where the moving speed is fast. Since it is moved to the rear relatively over time, it is possible to favorably clean the outside and the inside of the container 1.

Next, when the moving frame 15 reaches the retracted end position, the moving frame 15 moves forward in synchronization with the container 1, but at that time, the moving frame 15 is not at the same speed as the container 1. The container 1 is moved forward while being displaced relative to the container 1. In this example, when the preliminary cleaning nozzle 16 provided on the moving frame 15 is retracted to the retracted end position, the preliminary cleaning nozzle 16 is located beyond the center of the container 1 and on the rear side thereof. From that state, the advance of the preliminary cleaning nozzle 16 is started.

In FIG. 8, reference numeral d means a width corresponding to the diameter of the container 1, and the preliminary cleaning nozzle 16 is advanced at a speed higher than the conveying speed V of the container 1, whereby the preliminary cleaning nozzle 16 is moved. Is displaced relative to the container 1 from the rear side to the front side. When the pre-cleaning nozzle 16 reaches the forward end position, the pre-cleaning nozzle 16 is again displaced relative to the container 1 from the front side to the rear side due to the advance of the container 1,
The retreat of the preliminary cleaning nozzle 16 described above is started. Therefore, in the following step in which the preliminary cleaning nozzle 16 is advanced, the preliminary cleaning nozzle 16 is relatively displaced with respect to the container 1 so as to be swung back and forth, so that not only in the returning step described above but also in this following step. The outside and inside of the container 1 can be cleaned well.

Incidentally, the follow-up process of the pre-cleaning nozzle 16 is set to 1/3 of the whole process with reference to the center of the container 1, as shown in FIG. It becomes 2/3 of the process. In other words, the follow-up process of the main cleaning nozzle 4 is ⅔ of all the processes, and the returning process thereof is ⅓ of the whole process, and therefore the forward speed in the follow-up process of the main cleaning nozzle 4 is equal to the container transport speed V If you let
The return speed of the main cleaning nozzle 4 in the return step is doubled. Since the pre-cleaning nozzle 16 is interlocked with the main cleaning nozzle 4 so that its speed becomes 1/2,
If the return speed of the main cleaning nozzle 4 is 2V, the average forward speed of the following speed of the preliminary cleaning nozzle 16 matches the container transport speed V.

As will be understood from the above description, the preliminary cleaning nozzle 16 is used in the process of following the main cleaning nozzle 4.
Therefore, the cam curve of the disc cam 9 is set so as to satisfy the condition required therefor centering on the operation of the follow-up process of the main cleaning nozzle 4, while the pre-cleaning nozzle 16 Since the follow-up process is the return process of the main cleaning nozzle 4, in this case, the operation of the follow-up process of the preliminary cleaning nozzle 16 is mainly set so as to satisfy the condition required therefor.

[0016]

As described above, the conventional rinser includes the following step and the returning step. Therefore, when the container is washed by the above-mentioned conventional apparatus, the nozzle is not opened in the returning step of the nozzle. The inside of the container cannot be cleaned because it comes off. Therefore, it is not possible to devote the entire container transporting process in which the container passes over the cleaning device to cleaning, so that the cleaning efficiency deteriorates. Further, since a moving frame having a large mass reciprocates, an inertial force is generated, and there is a drawback that the entire device vibrates.

[0017]

In order to solve the above-mentioned problems, the present invention eliminates the return process from the conventional cleaning process involving reciprocating motions of a follow-up process and a return process and performs cleaning. It is a thing.

For this purpose, a holder for holding and transporting the container is the same as that of the conventional example, and a cleaning nozzle is arranged on the belt of an endless belt conveyor having an annular shape, and the annular belt is used as the holder in the chamber. In the cleaning area, the reservoir is slidably mounted on the lower surface of the belt in the cleaning area, and the pressure cleaning liquid can be supplied to the reservoir.

In addition, the holder and the belt having the cleaning nozzle have an angle in the horizontal direction in the cleaning area so that they intersect each other so that the cleaning of the container is not concentrated at one point and evenly distributed. It is configured to be washed.

That is, according to the first aspect of the invention, a plurality of holders for holding and transporting the container, and a chamber disposed below the plurality of holders and having an opening along the transport direction of the holders. A reservoir fixedly provided along the opening in the chamber and having an opening provided with a sealing member in the upper portion, a cleaning liquid supply pipe for pressure-feeding the cleaning liquid to the reservoir, and the plurality of holders arranged at equal pitches A container having a plurality of nozzles, which slides between the opening of the chamber and the seal member of the reservoir to seal the inside of the reservoir and holds the cleaning liquid in the reservoir from the nozzle to the holder. The present invention provides a rinser characterized by comprising an annular belt for injecting into a belt and a drive device for driving the annular belt, and sending the belt in synchronization with the holder.

Further, in the invention of claim 2, claim 1
The rinser described above is characterized in that the traveling direction of the holder that holds and conveys the container and the traveling direction of the nozzle that ejects the cleaning liquid intersect at an angle in the horizontal direction of the upper surface of the reservoir.

[0022]

Since the present invention has the above-mentioned means, the following effects are achieved in the invention of claim 1. That is, the container is held upside down by the holder and conveyed along the traveling direction of the belt. The plurality of nozzles provided on the belt are arranged at the same pitch as the container opening described above, and are moving in synchronism with the container opening.Each nozzle moves directly below the container opening and moves. When the nozzle comes above the reservoir provided in the chamber, the cleaning water pressurized by the cleaning supply pipe is supplied to the inside of the reservoir, so this cleaning water is sprayed from the nozzle and the inside of the container conveyed by the holder is To wash.

Further, in the invention of claim 2, since the traveling direction of the holder and the traveling direction of the belt having the nozzle intersect with each other obliquely, the holder and the nozzle advance in the conveying direction and come to the cleaning area on the reservoir. Then, the nozzle moves relatively little by little in the direction perpendicular to the traveling direction with respect to the container opening. Thus, at the inlet of the wash area above the reservoir, the nozzle is, for example, at the right end of the container mouth, moves to the left as the belt advances, and comes to the left end at the exit of the wash area, thus removing the wash liquid. It is possible to wash the entire container evenly by spraying not only at one point but also at various parts of the container.

A large number of omitted holes are provided, and the lower end 31c of the recess forms a belt retainer so that the belt 34 does not lift upward.

The reservoir 32 is fixed inside the chamber 31, and the belt 34 is inserted between the upper end of the seal member 33 provided around the upper rectangular opening and the belt retainer 31c. Is formed in the longitudinal direction. Nozzles 35 are fixedly installed at the center of the belt 34 at a pitch equal to the distance between the holders 2. The belt 34 is rotated by being interposed between the drive drum 36 and the driven drum 37, and is driven by a drive not shown. The motor travels in the direction of the arrow in synchronization with the holder 2 via the drive shaft 38. The forward path of the belt 34 slides between the belt retainer 31c of the chamber 31 and the seal member 33 of the reservoir 32 while being lubricated with the cleaning liquid, and travels at the speed V.

Although the belt pressing member 31c of the chamber 31 is shown as a sliding type member in FIG. 2, it can be pressed by a roller or a free belt conveyor having a circular cross section in order to reduce resistance.

Next, the operation of the rinser of the embodiment having the above construction will be described.

The container 1 is held upside down by the holder 2 and enters the upper side of the belt 34 at a constant speed V in the direction of the arrow. The belt 34 is driven such that the mouth of the container 1 and the position of the nozzle 35 are overlapped with each other and the belt 34 is synchronized with the velocity V of the holder 2. When the container 1 and the nozzle 35 move at the same pitch with the opening of the container 1 and the nozzle opening and come on the reservoir 32,
The cleaning liquid pressurized from the cleaning liquid supply pipe 40 is stored in the reservoir 32.
2, the cleaning liquid is sprayed from the nozzle 35 to the inside of the container 1 which advances synchronously as shown in FIG.
