• the fifteen tubes 1 thus separated still have an axial spacing from one another which corresponds to the spacing of the transport trays 3, ie they are arranged with the same pitch (see FIG. 6).
• the tubes 1 In order to achieve a tightly closed packing of the rows of tubes, the tubes 1 must be 'compressed' so that they lie against one another or touch.
• Each row with fifteen compressed tubes 1, which are compressed in the exemplary embodiment, is then deposited by a row converter 10 with holding suction cavities 11, which are arranged according to a "compressed" row (see FIG. 7), on lowerable base strips 12, of an intermediate store 13.
• the baseboards 12 are then gradually lowered to accommodate a next row of compressed tubes 1. The gradual lowering continues until a desired number of rows has been formed, e.g. B.
• the intermediate store 13 can be designed as a box, one movable side wall of which serves as a slide 16 through which all the tubes 1 accumulated in the intermediate store 13 move in one sliding movement an empty or already partially filled box 14 arranged behind the intermediate store 13 can be transferred.
• the box 14 may already be partially filled and / or may require further batches of accumulated tubes 1 for complete filling.
• the initially empty box 14 is arranged in a vertical position behind the intermediate storage 13 and is gradually lowered according to the degree of filling by means of a holding fork 17.
• the holding fork 17 is arranged by means of a swivel drive 18 on a linear drive 19 for height adjustment.
• the linear drive 19 By means of the linear drive 19, the holding fork 17 can be fixed in different height positions, each of which can preferably be controlled by a mechanical or automatic control system (not shown).

B. can be designed as a finger band 20, so that the holding fork 17 can comb through the finger band 20 into a position located under the finger band 20.
• the full box 14 ' is then on a preferably laterally arranged, for. B. executed as a roller conveyor 21, conveyor belt to a filling machine (not shown) or to a warehouse (not shown).
• the holding fork 17 moves from the lowest position into its uppermost position by means of the linear drive 19 and combed first the first lower finger band 20 and then a second upper finger band 20', which is parallel to the first is arranged offset in height and takes over a new empty box 14, which previously z. B. has been supplied by means of a conveyor belt, which may for example be designed as a second roller belt 21 '.
• the holding fork 17 After taking over the empty box 14 from the upper finger band 20 ', the holding fork 17 remains for a moment in a slightly higher position or position slightly above the upper finger band 20', is pivoted there by 90 ° by the swivel drive 18, so that the opening of the Box 14 is directed to the buffer 13 and behind the Buffer 13 is lowered to the required, possibly stored, working height and can hold any number of batches of additional tubes 1 until the empty box 14 is filled.
• the collecting device 4 assigned to the feed belt 2 for tubes 1 has suction prisms 5, which are present in the exemplary embodiment (see FIG. 3) in a number of eight suction prisms 5.
• the suction prisms 5 are individually driven and rotatable about parallel axes between the feed belt 2 and the group converter 7 and first take eight and in a second step seven tubes 1 from the transport trays 3 of the feed belt 2, so that a total of fifteen tubes 1 from the group converter 7 be included. It is also possible to provide more or fewer than eight suction prisms 5 in order to receive more or fewer tubes 1 from the feed belt 2.
• tubes 1 coming on the transport 2 are received on the collecting device 4 at the transfer points A, B, C, D, E, F, G, H by means of the suction prisms 5 assigned to each transfer point A to H.
• the transfer points A to D are already occupied.
• the following transport trays 3 are unoccupied and there are gaps L.
• the tubes that may have been there were discarded, for example by an upstream control system, and have already been eliminated so that the gaps L arise.
• the associated suction prism 5, which has not yet been filled with a tube 1 is not activated, ie the empty transport tray 3 passes through the collecting device 4.
• the suction prism 5 'at the transfer point E is only activated when a tube 1 approaches in a transport shell 3. If determined, for example by If a light barrier (not shown) that a tube 1 approaches the transfer point E and thus the associated suction prism 5 ', the suction prism 5' is rotated in the direction of the arrow (see FIG.
• the receiving position P4 is e.g. recognizable for eight tubes 1 of a first cycle as well as a slightly pivoted adjacent position 4 'which is briefly approached by the group converter 7 after the eight tubes 1 have been picked up. He then swings back into position P4 to start the second cycle with seven tubes 1, so that there are a total of fifteen tubes 1 in the group converter 7. Then he pivots into position P5, in which all fifteen tubes 1 are placed in a collating device 8 with holding prisms 9.
• the holding prisms 9 (see FIGS. 6, 7) of the collating device 8 contain suction cavities, ie the tubes 1 located thereon are subjected to negative pressure and are thus held on the holding prisms 9.
• the collating device 8 has fifteen holding prisms 9 which are arranged at a distance from one another.
• the holding prisms 9 with the tubes 1 are slidable z. B. arranged on two rods 23 and collapsible such that they are all in mutual contact, ie all tubes 1 of a row touch laterally (see FIG. 7).
• the row formed of fifteen touching tubes 1 is received in position P5 (FIG. 5) by means of the row converter 10 with suction cavities 11 and, after a pivoting movement (see the arrow in FIG. 5), in position P6 on lowerable base strips 12a, 12b, 12c of the intermediate storage 13 transferred and stored thereon.
• the row converter 10 performs lateral deflection movements (shown schematically in FIG. 7 with the arrow between the positions P7 and P8), so that an alternating packing of the tubes 1 (see FIG. 10b) can be effected, i. H. a type of packing in which the tubes 1 of each successive row are each arranged in a gap.
• a type of packing see FIG. 10a is also possible in which the rows are arranged exactly one above the other.
• the bottom strips 12a, 12b, 12c are lowered by an amount which corresponds to the desired packaging pattern (see for example FIGS. 10a and b) .
• the lowering movement is equal to the respective tube diameter multiplied by the factor 0.5 x 3 and in the case of the loose packing type according to FIG. 10a is equal to the tube diameter.
• further rows are put down and further lowering movements are carried out until the respectively desired number of rows or the desired degree of filling of a box 14 is reached.
• the intermediate store 13 also contains an upper front boundary plate 25, which is arranged at a distance, possibly also lowerable, to allow passage of one, possibly also several rows of tubes. Furthermore, a rear boundary plate 25 'is provided, the spacing of which is adapted with respect to the tube length and also serves to stabilize the tubes 1 which have already been transferred into the intermediate store 13 during storage in the intermediate store 13.
• two sets of base strips 12a, 12b, 12c and 12a ', 12b', 12c ' are arranged in the intermediate store 13 on three interacting chain drives 26a, 26b, 26c. All are driven together by a single motor via a sprocket shaft 27. After the lowest of all rows of tubes 1 stored in the intermediate store 13 on the base strips 12a, 12b, 12c reaches the base plate 15 and the slider 16 transfers or inserts all the tubes 1 into a box 14, the chain drives 26a, 26b, 26c and the additional base strips 12a ', 12b', 12c 'put together further rows of tubes 1 in the intermediate storage 13 to form a further tube package.
• the holding fork 17 is connected to a height-adjustable linear drive 19 via a swivel drive 18, as a result of which the height positions H1 to H7 can be approached.
• a swivel drive 18 At height H1, an empty box 14 is taken over by the holding fork 17 from the upper finger band 20 '. Then it is pivoted by 90 ° by means of the swivel drive 18 and transferred to a variable working height, which is determined in accordance with the filling level of the box 14, to the respectively required working height H3.
• the height H5 is approached.
