- the processing stations are also identified with Roman numerals I - X.
- the individual machining devices which are designated by Arabic reference numerals 1-10, are arranged around and above and partially below the rotary conveyor table 41. For example, it is assumed that the rotary feed table 41 rotates counterclockwise.
- the first station I has a feed device 1, through which the sleeves of the predetermined diameter and predetermined length are fed in the correct position and transferred to the receiving station I.
- the sleeve blanks can be provided with an external label.
- the processing station II has a pre-pressing and pre-compression device 2, by means of which the sleeve blanks turned further to the station II receive a conically tapering, but still open tip.
- the pre-pressed and pre-compressed cardboard tube is transferred to the processing station III, which uses a compression and rounding device 3 to carry out further compression and dome-like rounding of the tube tip.
- the tool used in the compression and rounding device 3 is explained in more detail below with reference to FIGS. 3B and 4.
- a pressure stamp carries out a press movement into the interior of the sleeve against a bell which is resiliently mounted on the machine stand 20 and which engages over the outside of the cardboard sleeve in the region of the sleeve tip.
- an anvil with a concave anvil surface, immovably fastened to the machine stand 20, is provided, which is used for rounding off the tip of the sleeve.
- the sleeve which has been compressed and rounded in the area of its tip in the compression and rounding device is then transferred to the processing station IV, where a smoothing device 4 which is also equipped with a pressure stamp and a bell is provided.
- a common machine stand 20 is preferably used for the machining devices II-IV.
- the sleeve thus provided with a smoothed and compressed dome-like tip is conveyed to the processing station V, where the sleeve tip by means of a printing device 5
- REPLACEMENT LEAF is printed with printing ink.
- the printing device 5 is preferably a pad printer. No actual machining of the sleeve takes place in the following station VI. This is only turned into its reverse position, with its tip pointing downwards, by means of a turning device 6.
- a gluing device 7 is provided, which brings a quick-drying hot glue into the interior of the sleeve in the area of its tip, which further increases the tightness of the sleeve tip.
- the subsequent processing station VIII contains a pre-flanging device 8 which simply flanges the edge of the open sleeve side.
- the edge is flanged further by means of a re-flanging device 9, so that it folds inward spirally.
- a further processing station X is provided with an ejection device 10 which effects the ejection of the finished sleeve.
- the entire rotary transfer machine 40 is controlled by a programmable logic control device (PLC) 11, which receives sensor signals from various sensors attached to the individual processing stations, which control the correct functioning of the processing devices.
- PLC programmable logic control device
- the PLC sends control signals to the individual processing devices I - X, so that a smooth and predetermined workflow of the rotary transfer machine is guaranteed.
- REPLACEMENT LEAF supply essential burr-free sleeve which is completely closed in the area of its tip.
- the tightness is improved after turning in station VI by the lighting in station VII.
- the pre-flanging and re-flanging in the processing stations VIII and IX finally forms at the open sleeve end an edge suitable for preferred use as a fireworks attachment sleeve, with which the sleeve according to the invention can be plugged onto a propellant sleeve in a sealing manner.
- FIG. 3A shows a tool which is preferably used in the pre-compression and pre-compression device 2 and which, in conjunction with the pressure stamp 17 shown in FIG. 4, carries out the conical deformation and the pre-compression of the sleeve tip.
- the inner contour 18 'of the tool part referred to as bell 19 is selected in accordance with the desired conical deformation and compression of the sleeve tip and to match the outer contour 18 of the pressure stamp 17 shown in FIG. Since in the pre-compression and pre-compression device 2 the sleeve tip is not yet completely closed, the bell 19 has an axial blind hole 21 into which the cardboard material of the conically tapered sleeve tip can expand.
- a predetermined number of plate springs is inserted between the machine stand 20 and an outer flange of the bell, so that the spring travel determines the pressing pressure.
- the maximum spring travel is limited by an elongated hole 23 in the tool neck and a pin attached to the machine stand 20 and passing through the elongated hole 23.
- the compression and rounding device 3 shown in FIG. 3B also has, as a pressing tool, a bell 29 which has an inner contour 28 which interacts with the outer contour 18 of a pressure stamp 17 according to FIG. 2.
- a bell 29 which has an inner contour 28 which interacts with the outer contour 18 of a pressure stamp 17 according to FIG. 2.
- the bell 29 is provided with an axial through bore 30 on the bottom of the inner surface of the bell 29, so that the latter is pressed by the pressure of the pressure die 17 around an anvil 31, which fits snugly through the through bore 30 of the bell 29 goes, can move.
- the pressing surface of the anvil 31 has a concave shape and corresponds to the convex contour of the dome surface of the pressure ram 17 pressing against it.
- the anvil 31 is rigidly mounted on the machine stand 20. Due to the construction shown in FIG. 3B, the compression and the dome-like rounding of the sleeve tip are carried out in the processing station III in connection with the pressure stamp 17. This can result in the cardboard material flowing into the very small gap between these edges in the area of the inner edge 36 of the bell 29 and the outer edge of the anvil 31, in particular when the tool is worn, which causes burr formation in the area of the sleeve tip.
- the cardboard material has already been compressed in the pre-compression and pre-compression device 2 of the processing station II, it can no longer penetrate as much into the gap between the edge 36 and the peripheral edge in the compression and rounding device 3 of the anvil 31 flow, which minimizes burr formation and tool wear.
- the pressed sleeve tip is smoothed in the subsequent station IV by the smoothing device 4, so that a burr which has nevertheless arisen is smoothed.
- the finished pressed sleeve is pushed off the stamp and turned by 180 ° with the tip pointing downward.
- stations VII and IX in which hot glue is injected from above with a hot glue nozzle into the inside of the sleeve in the area of the sleeve tip, the sleeve is fixed from below by a counter-holder and flanged inwards by a tool coming from above. This is done in two steps: At station VIII, the sleeve edge is folded tightly inwards. At station IX this flanged edge is further rolled up spirally.
- FIG. 5 shows a cardboard sleeve 12 produced according to the invention in a longitudinal section at the top and in a top view below
- the pre-flanging and post-flanging device 8 and 9 ensure that the flanging edge has the largest possible radius Has. This is important for a solid and tight assembly of the cardboard sleeve 12 serving as a container for phyrotechnical effect material on the propellant tube 16 of the fireworks rocket.
- a cardboard sleeve which is sealed on one side and which is particularly suitable for preferred use as an attachment sleeve on fireworks rockets can be produced in a rational and space-saving manner.
- a very flexible rotary cycle device can be made possible, which also permits subsequent changes in the production process.
- the cardboard sleeves produced with the described, preferred rotary transfer machine together with the described tools result in a large production yield at a high throughput rate, i. H. , there are very few unusable cardboard tubes.
