Device xun application of closure » foils on storable containers.

The invention relates to a device sum Application of lid-forming sealing foils to storable biw. storable, «honest part in Rows, groups or the like. Containers connected to one another and used as packaging for a wide variety of products by welding the foils onto the container edges. In particular, the invention aims at the manufacture of packaging consisting of containers which are specifically are suitable for food.

Packages of the aforementioned type generally exist from swei specific parts, namely a lower part, the several depressions, bowls or the like. Sum purposes the receiving of the xu packaging products, and an upper part, which consists of a simple, a lid forming the sealing film, which is on the lower Part is attached after filling the containers. The lower part is usually made of a thermoplastic Material made of existing film, in which the desired wells or cups lra vacuum and in the Heat is molded in or otherwise appropriately drawn in. .

Packaging of the aforementioned type are usually manufactured by means of machines that are extremely complicated and therefore their manufacturing price is very high. Such machines are suitable for all necessary for the production of such packaging Operations, starting from a simple thermoplastic

The task of the transport comb 6 consists in particular in transporting the groups of containers to a station at which a sealing film forming a lid 7 is put on, and then to another station where the different groups are divided into elements, which have a more or less large number of single containers include.

The transport comb has a series of teeth, the shape and inclination of which correspond to the outer shapes of the Container 2 are formed. The transport comb 6 is advantageously arranged interchangeably so that it can easily be through another can be replaced when on the machine other container forms are to be processed.

The transport comb 6 is controlled by a movement device worn, which raIt connected to the drive of the device 1st. More precisely, it can carry 6 swei vertical poles 8, the two movable frames 9 in the vertical direction can slide. The latter are on fixed horizontal guides 10 and can move horizontally back and forth.

Each of the two vertical rods fl is controlled by two levers

11 carried, which are arranged one behind the other and through a Central axis 12 are interconnected to form a joint mechanism in the form of a toggle lever. The axes

12 of these two mechanisms are by means of a spar 13 connected to each other, of a neck or collar 1 * 1 carries, on which a drive rod 15 is articulated. Preferably can change the position of the collar 1 * 1 on the spar

13 easily changeable for quick adaptation to changed «requirements« u achieve.

The opposite end of the drive rod is hinged at point 1 $ to a rotating or flywheel 17, which

▼ is carried on a motor shaft lfl. This motor shaft rotates in the direction of arrow f the drive rod 15 nn of the turntable 17 is such eccentrically chosen that the Qanse has a slider crank arrangement forms a reciprocating translational movement on Hol »13.

At both ends of the path of the Tranβportkamm fi supporting movement means are auseohwenkbare or wegklappenda Anschieße 19a, 19b Each vorgesehen® the "Ser stops a small located slightly spaced from the end of the vein" of the moving means and consists of a ratchet _p which is spring-loaded. This latch allows passage; of the corresponding end β of the movement device until it has completed its movement in this direction. The pawl against set, however, sees the reverse movement of the movement device until the moment when the corresponding stop 19a or 19b is swiveled out by a control member provided for this purpose. This control element consists of one lever each. One safety nose 20a _e 20h® each, which is carried by the corresponding knee lever and acts with the corresponding stop in the aforementioned manner, as also with reference to d «a äB» aRSi "R> The movement sequence of the machine is explained below 1st.

The sealing film 7 is formed by a web of thermally adhesive material which is dispensed from a storage drum or roller 21. These web travels a certain Ansahl steering rollers 22 before they _ß su a final deflection roller 23 passes is disposed immediately above the pass of the container groups. This last deflection roller © 23 is located on a pivot lever 24 which is under the action of a tension spring 25.

How it works, see below let.

This side and the other side of the most guiding unsteering role 23 the device has a filling station and a closing or sealing station. These two stations are in front of and when viewed in the direction of movement behind the last pulley 23. The filling station for For the sake of clarity, the storage container was shown in the Drawing not shown in detail.

For this purpose, the welding device 2 comprises component parts 6a and 6a, the first of which is firmly connected to the transport case 6, while the second is held by the movement device carrying it.

When this application is completed, the flehaltnase kicks 20h the toggle lever with the latch of the stop 19b is in operative connection and cancels its blocking (see Piss. 2). Then you can see the movement device with the Transport can move 6 further back, and »was due to the further movement of the drive rod 15 and thus of the spar 13

The return movement of the transport comb * 6 plays itself out so in a situation in which this does not affect the container bsw. Container groups on the guideway 3 has. Rather, they are located during the return movement des Transportkamnes 6 In rest position, and she know while this perlode is being filled.

Before the rear end is reached again, the movement device passes the latch of the rear end Stop 19a and Iflst this off immediately. The effect this stop 19a is practically the same as that of the front stop 19b, so that the movement device is then directly in the In Flg. 3 position shown persists.

By pulling the drive rod 15 onto the spar 13 is now the extension of the toggle lever 11 and thus the Raising the transport combs 8 6 to its starting position (see Fig. 1). Is the stretch and Lifting movement is complete and the transport comb 6 is in its working position, so the lust Switching nose 20 on the rear knee joint, the blocking of the stop 19a, so that the movement device again is released and can move forward, as described in the ready.

The inventive device receives the Transport comb 6 has a rectangular track that is approximately is divided into the following stages:

1. Forward movement in the raised working position,

2 lowering after reaching the front end of the direction,

3 · translational backward movement - in lowered

4. Raising in dl® starting days after reaching the rear In the end.

The pivoting lever 21 of the last deflection roller 23 can pivot in the absence of the arrow P ^ to the effect of the pluckers 25 , thus enabling the further forward movement of the front end of the polienbahn, so that the work process of the machine can be continued.

But as soon as the container from the Klenmbackpn the welding equipment; are released, the pivot lever reverses 24 as a result of the action of the peeler 25, which previously paned as a result of the press roll 30 stopping had been. As a result, the pivot lever 24 guides the front one At the end of the sealing film, up to a point the synchronism between the application of the inscriptions on the pole and those moved by the transport caran 6 Containers is restored.

This ensures that the next welding process always takes place in the intended manner, ie that the sealing film is always in the right place on the container. If a shift or deviation occurs in any lateral point, this can only affect the corresponding welding process. Such a shift is therefore not of particular importance and can practically be regarded as negligible. It is therefore not possible that any feed or loading errors add up in the course of the various operations, since after each work process the swivel lever 24 returns the VersehluAfoile 7 in the desired synchronization position if you start each time with a new welding device could.

Such companies therefore know due to the provisions of the invention Machine your production completely discontinue the packaging of such containers, their processing was previously only reserved for larger companies that had the opportunity to equip themselves with machines that handle all processes, including production the container carried out itself. Rather, it is now possible, because owners of the invention Device take a number of the containers to be packed in stock, which you can obtain from a manufacturer, who specializes in the sole production of the containers · You can easily see the large operational engineering and economics lend to that result from this rationalization.
