DE2924410A1 - Tobacco cutting machine loading system - has vibratory conveyor with predominantly vertical motion in accumulation zone - Google Patents

Abstract

The system is designed to load a tobacco-cutting machine. The tobacco may be steadily compressed into a compact mass on its way to the cutting area, while individual fibres are cut off. The tobacco, particularly ribs (2) is transported by a vibratory conveyor (27) into an accumulation zone(1), where components assemble at right angles to the transport direction. In the accumulation zone the vibratory conveyor motion has a predominantly vertical component,while on the way to it the component is predominantly horizontal.

Method and device for loading tobacco cutting machines Addition to patent application P 29 03563.0 from January 31, 1979 The invention relates to a Method for loading tobacco cutting machines, in which tobacco during its Conveyance from a feed area to a cutting zone by pressing increasingly closed a compact tobacco mass is compressed, cut off from the individual tobacco fibers be, the tobacco, especially tobacco stems, in a substantially through the course of the press zone determined conveying direction by vibratory conveyance in a Are conveyed into the storage zone of the feed area, in which they become one essentially horizontal and predominantly essentially transversely to the conveying direction aligned tobacco parts build up formed association, according to main patent ... (patent application P 29 03 563.0).

The invention also relates to a device for loading Tobacco cutting machines, consisting of two arranged one above the other, in the conveying direction press conveyors converging towards a mouthpiece, of which the lower press conveyor delimits a feed area to the baling channel formed between the two conveyors, wherein in the feed area is determined essentially in that by the baling channel Conveying direction extending vibratory conveyor opens.

With the procedure on which the main application is based or

the corresponding device of the above-mentioned type should while saving a relatively high congestion Stw .: KI'-direct loading vibrating conveyor add-on I created an optimal alignment with increasing pre-compression of the tobacco stems the tobacco ribs to be cut in an inclined bandage or transversely to the conveying direction in so-called pressed tobacco cake can be achieved to as high a proportion as possible from long-fiber rib cuts in the clippings.

The present additional application is based on the task of precompression to improve even further in the feed area, layering the tobacco stems horizontally aligned on layering or damming or pushing upwards to prevent the ribs on the tobacco mass in the press chain zone.

In addition, the delivery flow through the vibratory delivery should also fluctuate Feeding can be maintained without interruption as far as possible.

According to the invention, this object is achieved in that the vibratory conveyance the tobacco stems in the stowage zone of the feeding area a predominantly vertical conveying component and a predominantly horizontal conveying component on the conveying route leading to the stagnation zone granted.

The device for carrying out the method described above is characterized in that the vibratory conveyor at its the feed area adjacent delivery end on rocker blades inclined more strongly to the horizontal and at the opposite end of the feed facing away from the feed area, it is weaker towards the Horizontal inclined swing blades is mounted.

With the help of this procedure or arrangement, the tobacco stems are in the feed area shortly before delivery to the press chains, a predominantly vertical one Shaking motion suspended and compacted in layers while in the rear Stw .: KT direct loading vibratory conveyor additive I conveyor zone for a sufficient The material to be cut is replenished by predominantly vibrating impulses in the conveying direction is.

Particularly optimal conditions in terms of pre-compaction in the The feed area and the conveyance to the feed area have become advantageous Design proven by the fact that the swing blades are more inclined to the horizontal with an angle of the order of about 400 to the vertical and the weaker inclined swing blades at an angle of the order of about 200 to the Are employed vertically.

Stw .: KT direct feed vibratory feeder add-on 1 The invention will be explained below with reference to an embodiment shown in the drawing explained in more detail.

The tobacco cutter shown in the drawing has a feed area 1 for tobacco, in the present case for tobacco stems 2 on, which is directly in front of the inlet to a baling channel 3 extends, which by conveying means in the form of a upper press chain 4 and a lower press chain 6 is formed. The two press chains 4 and 6 are arranged converging to one another in the conveying direction, the lower Press chains 6 is extended towards the rear in relation to the upper press chain 4 and delimits the feed area 1.

The two press chains 4 and 6 can be driven by a drive 7, wherein the upper press chain 4 is also designed as a rocker or in a bearing 8 is arranged to oscillate.

a pressure generator 11 acting on one of its rollers 9.

The press chain 4 is silver gears 12, 13, 14 and a Katentrieb 16 can be driven by the drive 7 together with the press chain 6.

An upper part 17 is connected to the press chains 4 and 6 and a lower part 18 existing mouthpiece 19, the upper part 17 of which is the press chain 4 is assigned and can be moved up and down with this and its lower part 18 is rigid is arranged and forms the counter knife for knife 21, which on the circumference of a the mouthpiece 19 upstream knife drum 22 are arranged. The knife drum 22 can be driven by a knife motor 23. The knife 21 is used for grinding a grinding device 24 which is dressed by a diamond 26.

In the feed area 1 one opens essentially in the the baling channel 3 specific conveying direction extending vibratory conveyor channel 27, which runs at an incline of about 50 in the conveying direction. The vibrating conveyor Stw .: KT direct feed vibratory conveyor additive I derrinne 27 is powered by a motor 36 and an eccentric drive 37 with drive rod 38 drivable and on resilient Swing blades 28a and 28b mounted. Those arranged in pairs in the feed area 1 Rocking blades 28a are at an angle of 400 to the vertical and that at the rear At the end of the vibrating conveyor trough 27, a pair of vibrating blades 28b in one Set at an angle of 200 to the vertical. The stronger this way against the Horizontal inclined oscillating blades 28a produce a stronger, predominantly vertical one Shaking movement, whereby the tobacco stems 2 are layered tightly on top of one another are prevented that the tobacco stems 2 when attaching to the between tobacco mass 39 located in the press chains 4 and 6 build up or

are deflected upwards and are partially vertical place. The through a chute 33 in the rear part of the vibrating conveyor channel 27 entered tobacco ribs, however, are much weaker against the horizontally inclined oscillating blades 28 by acting predominantly in the conveying direction Shaking movements of the vibratory conveyor trough 27 influenced, so that for a continuous A replenishment of tobacco stems 2 in the feed area 1 is taken care of.

The vibrating conveyor trough 27 are also monitoring means 32 for Monitoring the queue area assigned, which is known for control purposes Way with the tobacco cutter or the loading conveyor associated drive means can be linked.
