Device for introducing rod-shaped objects into a container

The invention relates to the introduction of rod-shaped Objects in containers.

In the production of cigarettes, in which objects, e.g. cigarettes or filter rods are stored in containers, one must first introduce a smaller number of objects into the container, so that the container then in the desired vYeise can work. For example, in the South African patent specification 66/615 describes a container that at the beginning of each work cycle by hand Teilweiee must be filled, or must be monitored at least by an operator who initially supplied has to put otabe in the right position.

The object of the invention is now to provide a To create a device that makes it possible to fill a container at the beginning of the Püllun ^ rr / organgs ao that monitoring der / orriohfcung required only to a minimal extent iut.

More precisely. ^ Eoa ^ t the invention provides an arrangement uie one shoulder with parallel walls and one iodine umra.it, furthermore a support arm which uua oinar

Recording position in which he is essentially parallel to the. Extends bottom of the container, can be pivoted into a neutral position in which he practically no in the container Obstacle forms more, a guide element which extends over the 'taking its first position support arm away, a device for introducing rod-shaped objects into the Space under the guide element and above the support arm, which is in its first position, a device that reacts to the pressure the objects accumulating between the guide element or a curtain and the support arm responds to the support arm to cause himself to move out of his receiving position towards to move to its neutral position, as well as a device for holding together or guiding a large number of objects, which collect in the widening space between the support arm and the guide element, along a third Side, this device coming into effect at least until the point at which the accumulation on the bottom of the container Objects have reached their natural angle of shift.

The invention is described below in connection with advantageous details on the basis of schematic drawings Embodiments explained in more detail.

Fig. 1 shows in longitudinal section one end of an inventive Container at the beginning of a filling process.

Fig. 2 is similar to Fig. 1, but shows the container filled during its use.

Fig. 3 shows on a smaller scale the right end of the Container according to FIGS. 1 and 2 in a front view. .

Figure 4 is a longitudinal section through one end of another Embodiment of the invention.

Fig. 5 shows a curtain which can be used in both embodiments of the invention.

The container shown in Fig. 1 to 3 comprises parallel side walls 6, an arcuate end wall 7 and one that forms the bottom of the container and is represented by a

An arm 9 in the form of a flat plate is attached to an axis 10 and can be turned clockwise from the in -Pig. 1 shows the position shown in Pig. 2 position can be pivoted. The free end of the arm 9 carries a flap 11, which in its starting position according to I ¹ Xg. 1 is pivoted downwards and spsLteE assumes the position shown in FIG. The flap 11 is connected to the arm 9 by a hinge which allows the flap to pivot in only one direction. ■

In the upper part of the container there is a conveyor belt 12 which is attached to the arm 9 according to FIG. ^{5 1 Ig.} 1 stick-shaped objects, see 3. Filter rods or cigarettes, feeds, a curtain 13 extending over the arm is arranged over the arm 9. More precisely, the conveyor belt 12 feeds the objects to the space between the curtain 13 and the support arm 9, the curtain helping to keep the arriving objects in the correct position.

Above the curtain 13 is a pressure sensitive switch 14 arranged, which can cause the axle 10 to be driven and rotated clockwise.

A cam 15 »sits on the axis 10 through the one Switch 16 can be operated to switch on the drive device for the conveyor belt 8.

Above the conveyor belt 8 is a photoelectric detector 18 arranged, the rod-shaped objects in the presence of elk between the photocell and the light source causes the axis 10 to be rotated counterclockwise.

Jenn the container is empty, take the various Share their position shown in FIG. 1. Become rod-shaped Objects fed to the space between the curtain 13 and the arm 9, the curtain moves upwards until the Switch 14 is operated, vi / hen this happens, begins the Axis 10, together with the arm 9, in a clockwise direction

turn, Ms on the switch H no more pressure is exerted However, if objects continue to be fed, the arm 9 will move almost continuously.

As soon as the arm 9 passes through a vertical position, the flap 11 assumes an extended position with respect to the arm and carries along with one 'along the hinge on the cleat

11 attached curtain 17 to the objects in attachment to hold on the front wall 7.

As soon as the arm 9 has one in I ¹ Ig. 1 reached position above the rubble or ttuhewinfcßls of the objects, indicated by dash-dotted lines, the switch 16 is actuated in order to put the conveyor belt 8 into operation. If the fe arm 9 reaches the one in Pig. 2, the switch Ί6 "returns to its rest position, and the switch takes over the control of the conveyor belt 6, while the arm 9 is held in its position according to Pig. 2 by a brake.

if at any later operating condition the detector 18 'establishes the absence of objects, the arm 9 is made to move counterclockwise move "until it has reached its position after Pig. 1 again.

When the container is to be filled, it is only necessary to switch on the control devices and to cause the Pörderk ban'd 12 to feed rod-shaped objects to the container.

Furthermore, a curtain 19 is provided which initially .an the top of the arm 9 and helps to keep the objects in the correct position when the arm is _; 9 towards his position after Pig. 2 moves .. _

The curtains 19, 17 and 13 can be made of a rather heavy flexible material, or in the form of ^? i £> b must also be designed to be descriptive.

In the embodiment shown in FIG. 4, the Below is an end wall, but as before it comprises side walls 6 and a conveyor belt 8 forming the bottom a support arm 20 is provided, which is mounted on an axis 21 so that it can pivot between one in i'ig. 4 with can execute a first position indicated by dash-dotted lines and a second position shown with yoll lines, wherein the arm in its second position forms an end wall of the container.

Several curtains 22 to 30 work together with the arm 20, to hold together the rod-shaped objects that in this embodiment the container through a slot 31 are supplied, which opens above the arm 20 occupying its upper position in the container. The objects will by means of a rotatable device 32 along the slot 31 emotional.

Above the first position of the arm 20 is a pressure sensitive one Switch 33 arranged. When it reaches its second position, the arm 20 actuates a switch 36. In addition a light-sensitive detector 38 is also provided.

At least the curtain 23 is formed as shown in Fig. 5, i.e. its width is smaller than that Width of the container and as the length of the rod-shaped objects. I. The curtain comprises two flexible bands 40 between which rods 41 extend. In the curtain 23, the upper rods 41 are omitted * so that the sensing arm of the switch 33 can be actuated by the objects lying under the curtain 22. The other curtains can use the rods 41 make a full ladder, or you can you can the practically unneeded ijtangen near the top let go.

When the device is used, the arm 20 is initially in an au.jgun ^ astpartition indicated by dash-dotted lines. The curtains 22 and 23 are so arranged

net "that they emerge from the slot 31 rod-shaped Oppose objects with a resistance. If there is a steadily increasing amount of objects between the arm 20 and- the curtain 22 accumulates, a switch 33 is finally actuated so that the arm 20 is rotated counter to the direction in which it appears will. This movement continues with further feeding of objects until the arm 20 is shown with solid lines Position reached and actuated a switch 36 so that the device for driving the axis 21 is switched off and the switch 33 now controls the device for Driving the conveyor belt 8 takes over.

As in the first described embodiment If a detector 38 detects the presence of objects and causes the now taking place in a clockwise direction Return of the arm 20 to its starting position.
