Abstract

The invention relates to a device for filling the mass flow of continuously lowerable trays (1) with cigarettes (2) from a feed magazine. DOLLAR A The aim is to optimize the fill level of the slope both optically and numerically. DOLLAR A This is achieved by two rows of bars with upper and lower bars (11 and 12), which are offset by half the pitch and perform an oppositely oscillating lateral movement (54 or 56) and assume a locked position by a vertical relative movement (61) . DOLLAR A In this way, a downward movement of the cigarettes, which is directed obliquely downwards on both sides, is produced with a lateral distribution effect in the incline.

Description

The invention relates to a device for filling from below a feed gazins lowerable transport containers with rod-shaped articles of tobacco manufacturing industry, the bottom outlet of the feed magazine through a top and bottom rows of cross-axially reciprocable bars in number rich outlet openings for the items is divided.

With the continuous filling of transport containers in the form of so-called Slopes in the mass flow easily lead to gaps between the one individual rod-shaped articles in the form of cigarettes, filter cigarettes or filter rods ben, for example, not every article in one between two below located trough formed adjacent articles. It can too can happen that individual articles go wrong and in this way a hollow miss. In all cases there is not only a defective filler picture, related to the front of the article, but also an inadequate filling condition with too few articles or with different filling quantities the collar.

The invention has for its object a at higher flow rate better distribution of the articles in the tray and thus its better filling, ins special to achieve at the edges of the collar.

This object is achieved in that the rods of the upper Row of bars and the bars of the lower row of bars offset from each other and are designed to perform an oppositely oscillating lateral movement. The obliquely downward flow movement that occurs in this way  the article is further optimized according to a further proposal that the Bar rows or the bars of the bar rows in their basic position with half part are spaced from each other.

In order to change the tray, i.e. H. when replacing a filled slope the feeder magazine chute outlets were blocked against an empty tray ren, it is also provided that the vertical distance between the rows of bars is changeable, whereby after a training expediently in the reason position, the upper row of bars can be moved relative to the lower row of bars.

In order to achieve an unimpeded, even flow movement of the articles also provided that the bars of the upper row of bars have a rotary oscillation are trained to perform.

To leave a gap even in the particularly problematic side wall zone of the trays To create a seamless fill pattern, the rows of bars begin as far as possible side end of the feed magazine, d. H. as close as possible to the side wall of the Schragens, according to an advantageous development at least one side the feed magazine with a swingable wall part is that with the downward or upward movement of the upper row of bars into one Closed position or open position is pivotable.

The advantage achieved with the arrangement according to the invention is that for the individual outlet openings results in a shaft width for two articles and for this again a divided flow direction at an angle of 600, so that the Articles are optimally distributed with a side component, from which also a higher flow rate results. On the other hand, the effek tivere article throughput a reduction in the vibrating frequency of the rod rows, so that a gentler article handling is given and thus a reduced Tobacco failure associated with cigarettes.

The invention is described below with reference to an off in the drawing management example explained in more detail.

Here show:

Fig. 1, the feeding magazine of a Schrage filler according to the invention with controlled exhaust ports and associated drive elements,

Figure 2 shows the feeding magazine with associated drive members view. In the sides,

Figure 3 is a partial section from the feeding magazine and trays lung position. In the Befül,

Fig. 4, the feed magazine in the locking position of its outlet,

Fig. 5 shows the filling position of the feed magazine in the region of its one movable side wall and

Fig. 6 shows the locking position of the Zuführmagazins in the movable side wall in Fig. 5.

Referring to FIGS. 1 and 2, a transport container in the form of a so-called continuous Schragens 1 for the purpose of filling with cigarettes 2 below a cigarette 2 in the form of a mass flow 3 through sluice ends Zuführmagazins 4 is lowered. The tray 1 rests on a carrier plate 6 of a carriage 7 which can be moved downwards and upwards by means of a transport chain and vertical roller guides 9 not shown.

The lower, outlet-side end of the feed magazine 4 is divided into numerous outlet openings by an upper row of reciprocating bars 11 and a lower row of reciprocating bars 12 in their respective middle basic position with half a pitch apart from each other .

To generate the oscillatory movement of the upper rods 11 , a pivot unit 10 is provided, in which the rods 11 are rotatably supported in a support bar 13 , which is connected on both sides by pivot axes 14 , 16 with short-stroke cylinders 17 and 18 , which in turn on pivot axes 19th and 21 are mounted on a base frame 22 .

The swivel unit 10 forming a parallelogram or a parallel lever drive is driven by a drive means generating an oscillating movement, for example in the form of a crank mechanism 27 acting on a cam plate 24 via a crank rod 23 and a control roller 26 in contact with the latter on the short-stroke cylinder 17 .

In addition, the rods 11 are given a rotary oscillation movement by means of a rack 28 mounted on the carrier bar 13 and the drive cylinder 29 coupled therewith.

To generate the opposite oscillatory movement of the lower rods 12 , an additional pivot unit 30 is provided, in which the rods 12 are fastened to a support bar 31 , which is connected on both sides by pivot axes 32 , 33 to parallel levers 34 and 36 , which in turn are pivot axes 37 , 38 are mounted on the base frame 22 .

The swivel unit 30 is driven by an opposing oscillation movement generating means, for example in the form of a crank rod 39 on a cam 41 and a control roller 42 in contact with this on the parallel lever 36 acting crank mechanism 43 .

One side of the feed magazine 4 is provided in the immediate vicinity of the Schragensei tenwand with a movable side wall 44 which swings about a pivot axis 46 in the rhythm of the oscillatory movement of the rows of bars in and out and whose upper end with a tension spring 47 and its lower end over a loop 48 are connected with a tension band 51 guided around rollers 49 , which is attached to an angle plate 52 on the back and forth as by the short-stroke cylinders 17 , 18 in a locking position lowerable carrier 13 .

The rods 12 are also equipped with a freely rotatable spherical roller body 53 .

The operation of the tray filling device is explained in more detail below with reference to FIGS. 3 to 6:

With continuous lowering of the tray 1 shown in FIG 3, the rods lead. 11 and 12 of upper and lower row of rods by means of the crank mechanisms 27 and 43 from their respective central position opposite direction oscillatory movements in the direction of the double arrows 54 and 56 and the side wall 44 of the Zuführmagazins 4 according to FIG. 5 by the oscillating movement (double arrow 54 ) of the carrier 13 pulling and waning tension band 51 pivoting movements in the direction of the double arrow 55 and the upper rods 11 additionally a rotary oscillation movement in the direction of the double arrow 57 . The respective between two upper rods 11 sinking cigarettes 2 are deflected laterally and evenly in particular to the sides by the oscillating rods 12 in the direction of arrows 58 , 59 supported by the freely rotating roller body 53 at an angle of approximately 60 ° distributed in the tray 1 so that it is optimally filled optically and numerically.

When completely lowered, that is, a filled tray 1 Figure 4 of the rods 11, 12, the upper row of rods with the rods 11 in the direction of the arrow according to. 61 lowered so far by activation of the short-stroke cylinder 17 and 18 in a central normal position, that the cigarettes between the Rods 11 and 12 narrowed from openings can no longer happen.

By lowering the carrier 13 in the direction of arrow 61 , the drawstring 51 is pulled down so far around the rollers 49 that the side wall 44 is pivoted inward into a locking position according to FIG. 6. The bloc-labeled cigarettes 2 in this way prevent an uncontrolled falling of cigarettes into the trays 1 , which can be exchanged for an empty truss.
