Description

FIELD OF TECHNICAL APPLICATION AND BACKGROUND OF THE INVENTION

The present invention relates to a device for supplying bags and necks for them to a carousel for processing and to a corresponding method.

As is well known, more and more drinks, especially fruit juices and sports drinks, are sold and stored in soft containers, commonly known as “bags”.

Typically, these containers contain a bag, usually made of polyethylene, and a neck made with the possibility of leakage of the product in the container.

The outflow of the product is especially facilitated by the possibility of applying pressure to the beverage by squeezing the bag.

Soft containers or bags are made of two plastic sheets, the edges of which are welded together to form a hole.

Part of the neck is inserted into this hole and fixed inside the bag by welding. It should be noted that during such welding, the edges of the indicated holes are exposed to heat to partially melt them, so that they stick to the part of the neck inserted into the bag.

As a rule, the neck is inserted into the hole before filling the container.

Well-known complexes for processing packages containing carousel mechanisms with star-shaped wheels for receiving packages with their subsequent movement, which work together with one or more star-shaped wheels for filling and sealing packages.

An important characteristic of complexes with a carousel mechanism is the possibility of their functioning in continuous operation, which ensures their high performance.

To take full advantage of this opportunity, it is very important to ensure a continuous supply of packets to the processing star wheel.

At the same time, both packages and necks must be fed to the processing star-shaped wheel, as the bags themselves are assembled directly on the welding star-shaped wheels, for which a hole is made in these packages, a neck is inserted into it, and then the edges of the package are welded.

The unresolved problem is the provision of continuous supply to the carousel mechanism of both packages and necks.

SUMMARY OF THE INVENTION

An object of the present invention is to solve the aforementioned problem by providing a device in which it is possible to guarantee continuous supply of both packages and their necks to a carousel for processing.

Another objective of the present invention is to provide a device for the simultaneous supply of bags and necks to the carousel for processing.

The next objective of the present invention is to provide a device for supplying packages and necks for them, which is configured to provide high performance.

The next objective of the present invention is to provide a reliable device for supplying bags and necks for them, which is easy to manufacture.

A further object of the present invention is to provide a simple method for feeding bags and necks to a carousel for processing.

These tasks are completely solved by creating a device for supplying bags and necks for them to the carousel mechanism for processing and developing an appropriate method, which are characterized by the following claims.

BEST MODE FOR CARRYING OUT THE INVENTION

These and other objectives are set forth in detail in the description of the preferred embodiment of the invention and are not limited to the examples given with reference to the accompanying drawings, in which:

figure 1 depicts a front view with a partial section of the device for supplying packages and necks for them on the carousel for processing;

figure 2 is a schematic top view illustrating the operation of the device depicted in figure 1.

In figure 1, 2, the device for supplying bags and necks for them to the carousel mechanism for processing is generally indicated by number 1. At the same time, the carousel mechanism can be made, for example, in the form of a star-shaped bag forming machine equipped with welding grips for welding neck with bags .

The device 1 contains a first drive 2, configured to accommodate a set of packages 102 and a second drive 3, configured to hold a certain number of necks 103.

A completely new and original feature of the invention is the presence in the device 1 of the manipulator 4, made with the possibility of receiving from the respective drives the package 102 and the neck 103 and simultaneously supply them in continuous operation to the carousel.

In this example, the manipulator 4 is attached to a rotating platform 6 mounted on a key on the first support shaft 5.

Moreover, the manipulator 4 also contains a movable support structure 7 in the form of a second support shaft 7, made movable, namely, with the possibility of rotation around the first vertical axis A from the working position in which the package 102 and the neck 103 are received, in the working position in which they are transferred to the carousel mechanism. Means for receiving the package and the neck mounted on the shaft 7.

In this example, these means of receiving the package contain two suction cups 8, 9, which are vertically aligned and are located in one vertical plane P (in figure 1, the plane P is presented in side view).

In the presently preferred embodiment, the neck receiving means is a gripper 10.

As shown in figure 1, the shaft 7 is attached to the perimeter of the platform 6, rotating around an axis B, which is located essentially vertically and passes through the shaft 5. Strictly speaking, there is a simultaneous rotation of the shaft 7 around the axis A and the platform 6 around the axis B, so that the movement of suction cups 8, 9 and grab 10 from drives 2 and 3 to the carousel mechanism for processing packets and necks occurs through a hypocycloid.

According to the embodiment of FIG. 1, the platform 6 is driven directly by the carousel mechanism, for example, by mechanically connecting the gears 30 integrally with the carousel mechanism and the corresponding gears 31 integrally with the platform 6.

In this example, the shaft 7 is preferably driven by an electric motor 11 rigidly attached to the platform 6.

In the presently preferred embodiment, the device 1 includes one rotating platform and several shafts 7, each of which is equipped with at least two suction cups for receiving and holding the bag and at least one grip for receiving the neck.

The method of supplying bags and necks to the carousel for processing includes the following steps:

- preparation of the drive packages;

- preparation of the neck accumulator;

- receiving the packet (102) from the corresponding drive (2); and

- receiving the neck (103) from the corresponding drive (3).

A completely new and original difference of this method is the operation of simultaneous continuous supply of packages and necks to the carousel for processing.

In a preferred embodiment of the invention, the supply of packets and necks from the drives to the place of unloading on the carousel mechanism is carried out along a hypocycloid path.

The following describes the operation of the invention.

The platform 6 is set in motion directly by the carousel mechanism by connecting the gears 30 made in one piece with the carousel mechanism and the gears 31 made in one piece with the platform 6.

However, the shaft 7, which is part of the manipulator 4, is made to rotate around axis A by an electric motor 11, connected in one piece with the platform 6.

Thus, the suction cups 8, 9 and the grip 10 are moved along the hypocycloid from the receiving area of the packets 102 and the necks 103 from the respective drives 2, 3 to the transmission area of the packets and necks to the carousel for processing (indicated by the letter R in FIG. 2).

As shown in figure 2, the trajectory of movement of the suction cups 8, 9 and capture 10 contains a point Q. This point corresponds to the inflection point of the hypocycloid in drives 2, 3 containing packages and necks (only the drive with packages is shown in figure 2), in which the absolute speed of movement of the suction cups and grip is reduced to zero. Thus, the suction cups and grip can, without “pulling”, take stationary packets 102 and necks 103 from the respective drives.

Then, the point Q shown in FIG. 2 follows essentially along an arc of a circle, so that the relative speed of the suction cups 8, 9 and the gripper 10 with respect to the carousel mechanism R is zero. At the same time, with the indicated suction cups and gripper, it is possible to precisely move the packets 102 and the neck 103 to the rotary mechanism R.

Although the principle of operation of a device with one manipulator 4 is described above, such devices with several manipulators work similarly.

This invention has several important advantages.

First of all, the device in accordance with the present invention allows you to continuously serve and packages and necks and thus guarantees high performance.

Another important advantage of the present invention is the ability to simultaneously supply packages and necks.

Another advantage is the fact that the device in accordance with the present invention is compact and extremely reliable.

Another advantage of the present invention is the ability to safely manipulate bags and necks without damaging them while providing high performance.
