Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The invention relates to a device for pneumatically transporting rod-shaped articles, such as filter rods, in the tobacco processing industry to a plurality of downstream processing machines, which of the type having a conveyor and a plurality of outlets for the goods reservoir, which are connected via pneumatic conveying conduits to downstream processing machines, and having storage containers assigned to the distribution station. related to things.

The concept of "rod-shaped articles in the tobacco processing industry" in the prior art includes, for example, filter rods, but the pneumatic transfer device of the present invention can be used to convey rod-shaped articles other than filter rods in the tobacco processing industry, such as rod-shaped articles with filters. cigarette,
It can also be used to pneumatically transfer chigarillos, cigars and unfiltered cigarettes, chigarillos and cigars.

A transfer device of this type as a connection between a filter rod manufacturing machine and a downstream processing machine in the form of a filter mounting machine is known, for example, from U.S. Pat. No. 3,789,744.

Details of storage containers for installation in devices of this type are described, for example, in German Patent Application No. 3,333,859.

In practice, for example, two or three post-processing machines
At least consider the type of filter rod that will be used with the incoming product, so that other post-processing machines require filter rods of different quality (configuration) or different size, length, diameter). It is often necessary to transport parts. To date, this has required relatively expensive modifications and additional transport devices in the form of pneumatic transport stations have had to be provided and connected.

OBJECT OF THE INVENTION The object of the invention is to improve existing transfer devices in such a way that they are more flexible and have a wider range of use.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides that the storage container is divided into separate chambers each having a portion of the outlet, each having its own separate conveyor. I made sure that I was assigned.

Effects of the Invention The effect achieved by the invention is that one and the same transfer device can be used to supply a given type of filter rod to a downstream processing machine part as required, and at the same time to supply a certain type of filter rod to another part of the processing machine. It is possible to supply different types of filter rods to each other, and that the different filter rods on separate feed paths are conveyed to different sections of the storage vessel.

Embodiment According to one advantageous embodiment of the invention, the conveyor is designed as a flow conveyor.

According to a further advantageous embodiment of the invention, the storage container is divided into two chambers by a partition element.

2.3 Due to the different processing machines, the types of predetermined filter rods required for these processing machines are different, and in order to meet this condition, according to another embodiment of the present invention. For example, it is ensured that the storage vessel is divided asymmetrically so that both chambers are assigned a different number of outlets, or that the storage vessel is divided symmetrically so that both chambers are assigned an equal number of outlets. be done.

According to a further embodiment of the invention, the partition element is designed as a plurality of differently shaped partition plates that are replaceable and can be installed in the storage container, so that the storage container is subjected to varying operating conditions. The idea of the invention is to use flexible or movable partition plates to separate or open a corresponding number of discharge chutes for each chamber. Also included.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawing shows a distribution station 1 for pneumatically transferring filter rods to a downstream processing machine, which is not shown. The distribution station 1 has a storage container 2 which is equipped with ten outlets in the form of discharge chutes 3 at the bottom. Each discharge chute 3 is assigned to a transport station 81 to S10, which transport stations S1 to S10 are equipped with a transport device for transporting the filter rods into a pneumatic transport conduit. Details not shown specific to this transfer device are described in U.S. Pat. No. 3,827,757.

The storage container 2 is divided into a chamber A and a chamber B by a partition member in the shape of a bent partition plate 6a as follows. That is, three discharge chutes 3 or conveyance stations 81 to S3 are assigned to the chamber A, and seven discharge chutes 3 or conveyance stations 84 to S1 are assigned to the chamber A.
It is divided so that 0 is assigned. storage container 2
In addition to the embodiment of the partition plate 6a that divides the room into chamber A and chamber B in different proportions, there are partition plates 6b and 6 shown by dashed lines.
Variations of c are also possible. The partition plates 6b and 6C are
The partition plate 6 divides the discharge chute into chambers A and B and assigns the corresponding transfer stations to chambers A and B.
In the case of b, the ratio is 426, and in the case of the partition plate 6C, the ratio is 5:5.

The partition plate 6 is attached to the casing wall 7 of the storage container 2 as a changeable element that can be easily and quickly replaced.

Conveyors 8, 9 in the form of flow conveyors communicate with the chambers A, B of the storage container 2, which conveyors 8, 9 are connected between the upper conveyor belt 11 and the lower conveyor belt 12, respectively. Then, chamber A is supplied with a first type of filter rod F1, and chamber B is supplied with a second type of filter rod F2. Filter rod F1. Flows 13, 14 of articles formed from F2 are described, for example, in British Patent No. 2104858.
This is achieved by being ejected from the pedestal by a so-called pedestal ejection device in a manner known from the specification.

Thus, in the illustrated embodiment, three filter loading machines transport the first type of filter rods F1 via transport stations 81 to S3 and the second type of filter rods F1 via seven filter loading mechanical force transport stations S4 to S10. A type of filter rod F2 is supplied.

The filling state of chambers A and B is in a known manner, and the filter rod F
