DETAILED DESCRIPTION OF THE INVENTION

[0001]

This invention relates to a rotary rinsing machine provided with means for controlling and dispensing liquid or gaseous substances for handling bottles, jars or other similar containers. About.

[0002]

BACKGROUND OF THE INVENTION As is well known, prior to filling such containers with liquid food material, the interior surfaces of such containers are cleaned and aseptic in order to clean the containers.
It is necessary to treat these containers in one or more of the following steps: washing, blowing, rinsing and sterilizing.

[0003] Currently, several rinsing machines are provided that can perform the above operations automatically. In general, such machines are provided with a device for gripping the bottles, which are fed in a path such as a merry-go-round so that they can be located close to the nozzles supplying the substance to be treated.

[0004] Each of the nozzles must be connected to a supply line. The supply lines are alternately opened and closed according to the position of the bin and the processing time received by the bin.

Currently, devices for controlling and performing such processing steps are particularly difficult to adjust and synchronize opening and closing times for some conduits of a merry-go-round machine. There is a defect due to the presence.

[0006] In fact, known control devices are usually provided with a centrally located distributor of the merry-go-round machine and have a disk with slots. The slots are arranged along a round sector of the edge of the disk itself. The opening of the various conduits is in fact controlled by the position of the slot with respect to the control device. Obviously, when it is necessary to change the number of nozzles operating simultaneously, or the time of interruption, the control disk must be modified and adjusted. However, adjustment of the disc is achieved only by empirical and inaccurate operation.

[0007]

The main object of the present invention is to provide a new device which facilitates the control of the opening phase of the valve, in particular the width of the operating sector.
It is an object of the present invention to overcome the above-mentioned disadvantages due to the difficulty in controlling the known dispensing device.

[0008]

This device is provided with an adjusting member having a specific function. The function is
Determining when to start opening a valve located along the merry-go-round machine and determining when to close the valve. And, for example, when it is necessary to achieve an automatic hygiene process, there is the possibility of varying the width of the various operating phases and keeping all valves open.

The above objectives and functions are attained by the present invention relating to a rinsing machine or the like, more preferably a rotary rinsing machine. The present invention provides a series of supply pipelines for supplying a substance to a delivery nozzle and a control distribution device for dispensing a substance for processing a bottle, a pot, and the like, and an open / close valve is provided along the supply pipeline. And a liquid center feeder, the liquid center feeder being located at the center of the rinsing machine, wherein the valve has an opening device attached to a control piston that determines the opening of the valve. And at the side opposite to the opening device, also connected to the closing device for closing the valve, the angle formed between the opening device and the closing device around the liquid center feeder. Is characterized in that it can be adjusted. In one embodiment, the opening device comprises a roll, which is located at the end of a piston, which is controlled by a photocell or similar sensor, which detects the presence or absence of the object to be treated. It is designed to detect. In one embodiment, after a fixed time or a regulated time following the opening of the valve, the valve is adapted to be closed by the closing device with a friction mechanical device or an automatic piston device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

As shown in the drawings, 1 is glass, pottery,
Overall dispensing equipment mounted on a rinsing, blowing or sterilizing machine, preferably a rotating merry-go-round machine, for processing bottles, jars or other containers made of plastics material or other materials Is shown.

In these machines, a bin grip assembly and a series of injection nozzles 2 are provided. The bin grip assembly and the nozzle are both already known, and in certain cases they are provided along an annular merry-go-round, or carousel, machine.

Each nozzle 2 is connected to a valve 4 by a pipeline 3
Are connected via Each valve 4 is provided with a horizontal slider 5 for opening or closing the valve itself. Each valve is connected via a pipeline 6 to a liquid center feeder (a central feeder for supplying liquid) 7. The liquid center feeder 7 is mounted at the center of the machine.

The support member 9 is a central shaft 8 of the machine.
And the first supporting the piston 11
A second bracket 12 that supports the bracket 10 and the roll 13 is provided. Both the piston 11 and the roll 13 have a vertical axis. According to a possible variant, said bracket 12 may be replaced by a second piston for automatic control.

Both the brackets 10 and 12 are angled about the axis of the shaft 8 with respect to the support member 9 so that both brackets are located in the desired positions in control. The lower end of the rod of the piston 11 supports the roll 14. When the rod is lowered, the roll 14 intercepts the horizontal slider 5 of the valve 4 and presses inward, opening the valve so as to enable the supply of the processing substance from each nozzle 2. Let it.

The photocell 15 causes the piston 11 to intervene when detecting the presence of the object to be processed.

When the photocell detects the presence of a bin,
The photocell sends a pulse corresponding to the piston 11, which lowers the roll 14 and opens the valve. The roll 13 is mounted at a certain angle away from the opening device consisting of the piston 11 and below the feeding direction of the merry-go-round machine.
The roll 13 acts on the side surface of the slider 5, and the side surface of the slider is directed to the inside of the valve 4.

Contrary to the opening device, the roll 13
Performs a push and a displacement towards the outer part of the slider 5 and after one working cycle the valve is returned to the closed position, determined by the angle separating the rolls 14 and 13. The opening operation of the piston 11 and the closing operation of the roll 13 are continued until the photocell detects the presence of a bottle during the rotation of the merry-go-round, that is, the carousel machine.

In fact, all the valves 4 are arranged concentrically with respect to the nozzle 2 and therefore their operating radius is equal with respect to the center of the merry-go-round machine. As a result, the rolls 14 and 13 intersect with the slider 5 of the valve as it progresses to open or close the valve.

The angle adjustment of the brackets 10 and 12 is as follows.
It is possible to change the relative period between the opening period of the valve and the intervention (interruption).

As mentioned earlier, the bracket 12
May be replaced by a further piston (not shown) that can eliminate the roll 13 in order to keep all valves in the open position. This is particularly advantageous when it is necessary to perform an automatic sanitary process in which a suitable cleaning liquid has to pass through all nozzles.

Now, the washing step is performed so that the roll 14 opens all the valves 4 of the merry-go-round machine and the liquid from the liquid center feeder 7 exits from all the nozzles 2 of the merry-go-round machine. This is done when the piston is lowered and held during this lowering.

The end of the hygiene process is performed by returning the roll 13 to the start position. The return of the roll to the start position moves the slider 5 backward to close the valve 4.
