Procedure and device for packing

Objects

The invention relates to a method and a device for packaging τοη objects! in particular for cigarettes, or for packaging partial quantities of a product.

In the case of the herkon »], I en process for the division of dis Packed cigarettes, a machine is usually used to make and soften cigarettes a conveyor belt, usually referred to as a tether. The cigarettes are either from the tether mechanically or by hand into a portable container, usually referred to as a trough, as a receptacle filled with several thousand cigarettes, after filling the trough on the manufacturing machine, it will either by means of a conveyor or by means of a truck to a packaging bsw. Conveyed packing machine on which the cigarettes are counted in groups of a predetermined number, usually in an amount of twenty pieces each and then be packed.

In a typical packing machine, the cigarettes are filled from the trough into a filling funnel or shaft, from which groups of usually twenty pieces are counted and arranged in the position relative to one another which they are to assume in the finished pack. Each counted group is then sideways compressed and pushed endwise into a hollow mandrel which is used for receiving and which is open on both sides and at the end of the recording is extended outwards to include those in it to carry cigarettes pushed into them. The hollow mandrel has somewhat smaller * internal transverse dimensions than those of one finished cigarette pack, while its external transverse dimensions correspond approximately to those of the finished pack. The hollow mandrel, however, is a little longer than that finished pack.

After the hollow mandrel has been filled, it will be dispensed around an inner envelope or envelope that closes this end is formed. Then around the inner Envelope wrapped around a sleeve or a paper envelope carrying the tax stamp. Thereupon be the cigarettes pushed out of the hollow mandrel via the closed end, whereby they the inner wrapping and take the hull with you. Since the cigarettes had been squeezed tightly together, they stretch when

Leave the cave dorne * and fill out the inner envelope. The open load of the inner envelope then becomes locked. The inner envelope is usually made of paper-coated foil. Across the open A closure strip is then attached to the end of the sleeve.

The packs completed by the packing machine are then transferred to a wrapping machine in which they are in one usually made of clear plastic, such as Cellophane, existing outer wrapping to be wrapped.

The cigarette machines in use today produce the cigarettes at a manufacturing rate that is about half that amount a packing machine can pack. For this reason, there are usually around twice as many cigarette machines how packing machines are applied. The output length of the packing machines is limited by the slowest of the operations carried out in them, namely by the counting and Hollow mandrel filling process.

By the invention, this operation is eliminated as Begrenzungefaktor for Arbeltsgeschwindigkeit the Fackmaschine _f so that the packing machine, the ejection amount of more alβ two cigarette Herstellungsaaschinen can process shown below.

The hollow spines for receiving the cigarettes during dee Packing process were previously carried out on a conveyor, attached like a revolving drum »with the hollow spines be conveyed to and away from specified locations and not optionally carried out to other locations can. Palis a disturbance of the Paokaaschlne occurs, mufl the whole packing process, including the transfer of the cigarettes to and from the machine, is interrupted because the funding processes are not to be corrected this disorder can be changed ·. In the invention if, on the other hand, the hollow mandrels are not attached to a conveying device and preferably also do not have flared bsw. extended ends up. Extended guides are only used at the hollow mandrel flushing points. As a result of the In the absence of the widened ends and the attachment to a conveyor device, the hollow mandrels can easily be used, for example, to be transferred to others in the event of a machine failure Places are brought and the packing process is also significantly accelerated.

These advantages are achieved according to the invention in a method for packaging objects or partial quantities of a product in that several freely movable Hollow mandrels to several workstations and yen them away be promoted, the hollow mandrels at one of the work

The inventive device for performing this Verfahrene uses a freely movable hollow mandrel for the packaging of a product · The following was used The expression "freely movable hollow mandrel" is intended to refer to a refer to hollow container that is not rigidly attached to a device, but is freely movable in the sense, that it can be transferred from one place to another and in particular to any of several optionally possible places. The hollow mandrel is designated as freely movable, although it is for example by means of any mechanical or magnetic support member is held on a conveyor. The above expression means that the hollow mandrel is free of support in one or more places, so that it is, for example, of the one Conveyor can be brewed to another

By creating such a freely movable hollow mandrel, a product to be packaged can be attached to a hollow mandrel peeling unit, for example on the manufacturing machine

Thereafter, the casing and the product can be separated together from the hollow mandrel and the casing can be completed so that it completely encloses the product. The emptied hollow mandrel is then returned to "the filling unit and refilled with the product to be packaged" Such a system is suitable for providing successive work stations, such as collecting stations, in which either filled or emptied hollow spines collect. If, when using the freely movable hollow mandrel, for example, an enveloping sole su long «works to constantly remove all objects to be packaged from The hollow mandrel filled with the product to be packaged can be stored in order to be able to record the same at a later point in time or to be fed to another wrapping machine.

When packing cigarettes, a typical work sequence can consist in first removing the empty hollow mandrels to fill with cigarettes and then wrap them in the inner wrapping. The conveyor system can Collection stations for collecting empty hollow mandrels as well

It is particularly advantageous to get the cigarettes straight from the cigarette machine to the free one to transfer movable hollow spines »because of this the risk of deformation and damage to the cigarettes is largely reduced by handling, conveying and storage, because the hollow mandrels in turn a Form damage-avoiding holder for the cigarettes. The hollow thorns filled with the cigarettes can then be delivered to one or more locations with the help of a conveyor belt or some other device, on which the packing and packaging machines as well as the collectors should preferably be arranged. As a result of this arrangement, the manufacturing and packing and wrapping machines can be operated as a group, whereby the shutdown of one or more machines does not impair the functioning of the overall system, as the hollow mandrels for the purpose of further treatment through various combinations of processing nasalines and from others Machines can be diverted.

In position, the hat rests against a crosspiece 208 which forms part of a rod 210. This rod 210 can be driven by a collector lifting mechanism 212 which, for example, is coupled to the rod 10 via a support device 213, so that it is able to go back and forth continuously, even if the catch 204 is an upward movement of the rod 210 prevented. The rod 210 ends in an L-shaped plate 214 which, according to FIG. 7, can pass through between the conveyor belts H6a and ¹ 4 6b. The cross piece 20Θ provided on the rod 210 is also prevented from moving upwards by a box 216 which is coupled via an ann 218 to the arm 166 connected to the mandrel catch 162. When the catch 162 is pivoted by a hollow mandrel in the position for transfer to the conveyor 180, the ann 218 is also displaced and the catch 216 is pivoted away from the crosspiece 2C8. When all of the conveyor mandrel sensors 194 have been actuated, indicating the presence of a hollow mandrel 198 under the collector 200, energizing the solenoid 202 and pivoting the other cam 204, the elevator drive 212 moves the rod 210 upwards, with the plate 214 pushed the hollow mandrel 198 filled with cigarettes upwards into the collector 200
