The concept of cigarette means a cigarette made of tobacco or other smoking material, with or without a filter, in particular a filter rod made of a filter material (eg cellulose acetate) coated with a coating material (eg paper). I do.

[0003] These filter rods are often filled into containers after their production has taken place. Such a container is a shipping carton in which the filter rod is shipped. These containers are also intermediate storage containers, so-called trays, in which the filter rods are filled in the factory at their production site and subsequently emptied again for the production of filter cigarettes. In both cases, it is desirable that the large number of articles in the container be stored as uniformly as possible. In addition, the honeycomb layer design must be achieved by the individual cigarette rows being offset by half a diameter each with respect to the upper and lower adjacent rows of articles, and the total volume of articles in the container. As smooth a surface as possible must be achieved.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a tray filling device. The tray filling device is supplied with rod-like articles in the tobacco processing industry, in particular filter rods (or even cigarettes), transversely to their longitudinal axis, between two belts and between 2 and 3. These rod-shaped articles A
2 to 7 are not shown closely, unlike in practice, but are spaced apart from one another in order to better understand the function of the structural elements described below. At the end of the mass flow 5 there is a flexible membrane 4 which rests on the article and moves up and down in the turning area 7 corresponding to the article quantity 6. By controlling the belts 2, 3 in a known manner, the photovoltaic cells 8, 9 and 11 make it possible to supply the correct quantity of articles per unit time. Below the turning area 7, the inflow area 12 of the tray filling device 1 is enlarged by the flared walls 13, 14 to approximately the width of the container 16 for filling the articles. These containers may be open trays.
Moreover, these containers may be other containers, for example so-called shipping cartons. The side wall of the container 16 is designated by reference numeral 1.
6a, 16b and the dorsal side by reference numeral 16c. The inflow area 12 corresponds to an HCF type tray filling device known to the cigarette industry for the applicant's manufacture.

Below the inflow area 12 is a vertical shout 17 having vertical walls 18 and 19. The turning area 7 and the inflow area 12 thus form an accumulation zone for the articles to be supplied, below which the short 17 formed by the walls 18, 19 lies. . Therefore, this shot 1
Reference numeral 7 denotes a chamber in which a fixed amount of articles is accumulated. From this chamber, a certain quantity of articles is transferred into the container 16 in the direction of the longitudinal axis. For this purpose, the bottom plate 21 which is fixed to the laterally troughed belts 22, 23 and is provided with troughs has a belt 2 and 3 corresponding to the supply of articles.
(Details are shown in FIGS. 4 and 6). For this purpose, drive mechanisms 24 and 26 by motors driving the trough belts 22 and 23 work. Alignment rod 27 fixed to strip 28 while bottom plate 21 is descending
Reciprocates according to the two-way arrow 30. A drive mechanism 29 driven by a motor drives the strips via the excenter 31 and the connecting mechanism 32 to reciprocate on a flat ring-shaped trajectory. The movement of the orienting rod 27 causes the articles to be offset such that the individual article layers are offset by half a diameter of the articles above and below the adjacent arranged layers. Is molded.

When the bottom plate 21 with the layers has reached its lower end position, a push plate into the container 16 provided behind a certain quantity of articles arranged in the chamber 17 in a regular array. The transfer by 33 is performed. This push plate is moved forward and backward in the direction of the two-way arrow 36 by the piston actuated by the compressed air of the cylinder-piston system 34, so that the article A is vertical during the “lift” in the direction of the container 16. It is pushed / transferred into the container 16 in the direction of the axis. Reference numeral 37 designates a guide rod for the push plate 33. The air connection is not shown in the cylinder-piston system 34. After a certain amount of articles have been transferred from the chamber 17 into the container 16, the container is filled and removed by the method described below, and an empty container is placed in its place.

[0010] During the transfer of the article A into the container 16 and the discharge of the filled container, the articles present between the walls 18 and 19 must be prevented from sliding down. No. For this purpose, a push-in device 38 operable before the actuation of the drive mechanism 34 for the push-in plate 33 acts. The push-in device axially pushes one or many articles of the article layer A1 in a fixed number, so that the articles lying above the articles are pushed in during the transfer and the container change. On the part of the pushing device, which makes it impossible to slide down. For this purpose, a pushing strip 41 in which a bolt 42 is fixed acts. These bolts are surrounded by a spring 43 and act on pushing members 44 provided in rows. When the pushing strip 41 is slid by the driving mechanism 46, a pressing force is applied to the spring 43, and the bolt pushes the pushing member 44, which pushes the article A of the article layer A1.
Slide in the axial direction. Instead of a single article layer A1, it is also possible to slide two or more article layers upwards to block the load-bearing articles. On the opposite side of the article, on the mounting strip 45 there is a return strip 47 which presses the spring 48 when the article layer A1 is slid. After the end of the pushing movement in the direction of the return strip, the slid article layer A1 remains in its position under stress, and the articles provided above it during the transfer process by the pushing plate 33 and It works so as not to slide down during the container change. In addition, the articles rest on the push members 44 in their end regions. Thereafter, the transfer process is performed by the pushing plate 33. Prior to this transfer stroke, the drive mechanisms 42 and 26 lower the trough plate 21 and the array in chamber 17 by a small distance.

After the transfer process for the quantity of articles from the chamber 17 into the container 16 with the aid of the pushing plate 33 has been completed, ie after the pushing plate 33 has been moved back to its starting position by its drive mechanism 34 again. , The drive mechanism 46 also moves its piston rod in the opposite direction. Therefore, return strip 4
7 pushes the article layer A1 and the pushing member back to the starting position again under the action of the spring 48. In this case, the article layer A1 is again held by the pushing member 44 and the return strip 47.
After being returned, the article layer A1 is in the same position as the article layer lying above it in the axial direction, during which it is taken up by the trough-shaped bottom plate 21 which has been lifted up again. Thereafter, the troughed plate is lowered again in the manner described above, thereby again forming an array of articles in the chamber 17. Thereafter, the drive mechanism 46 for the pushing device 38
The transfer process is started by operating the drive mechanism 34 for the pushing plate 33. This transfer stroke transfers the formation into a new empty container.

FIG. 4 shows a driving mechanism 46 of the pushing member 41.
The details are shown. A pressurized cylinder-piston device 49 known per se is loaded by compressed air via a pneumatic connection, not shown, whereby its piston 51 acts on a movable plate 52 of a parallelogram provided with a plate 53. . Thereby, the plate 52 is slid in the direction of the two-way arrow 30.

The empty container 16 is present on a conveyor belt 56 which slides in the direction of arrow 57 to supply the above-mentioned container 16.1 to the filling station. For lowering into the filling position 16.2, the chain wheels 63 and 64
Drive mechanisms 58 and 59 by motors that drive the chains 61 and 62 guided around are operated. Chain 61
And 62 transport the containers 16.2 on their conveyor belt 66 after their filling, which transports them in the direction of arrow 67. These empty containers are supplied to the conveyor belt 56 either manually or automatically, and the full containers 16.2 are manually or automatically removed from the conveyor belt 66.

FIG. 2 and particularly FIG. 7 show the trough belt 22 having the trough 22a and the article A in an extremely enlarged manner. The radius R of the trough is significantly larger than the radius of the article A. Each of these radii is the distance S from the center point of the second article A2 to the trough 22a.
Slightly larger than. The maximum spacing between the troughed belts 22 and 23 advantageously corresponds to the number of articles in one layer times the article diameter + 1/2 article diameter. Such dimensions facilitate re-sliding of the article and formation of a uniform layer on the article "on the gap" due to the unequal number of articles in the successive layers. Thereby, the bottom plate 22 in the chamber 17 is
Above and between the troughed belts 22 and 23 there is a very uniform arrangement of the articles, which in particular indicates that the reference numeral 16 indicates that the articles have been put in and sold from the factory to the next processor. This is important if the shipping container is used.
