Definitions
- the invention relates to a device for evacuating and closing bag packs according to the preamble of
- Claim 1 as has become known for example from DE 40 13 273 AI. Such devices are part of packaging systems on which, for example, bag packs filled with coffee are produced. The known device has one for each bag pack
- Evacuation chamber the two evacuation chamber halves of which can be moved against the flat-folded head closure protruding from the shoulders of the torso of the respective bag package, and accommodate this during the evacuation and closing process.
- Head closure of the sealing jaws forming the bag pack are arranged in the evacuation chamber halves.
- the performance of the known, cyclically operating device is due to the time required for the closure the evacuation chamber and the evacuation of the contents of the bag. For this reason, several similar devices, for example four devices, are used simultaneously in high-performance packaging systems. To do this, one
- Bag pack during a standstill phase of the conveyor device transporting the bag packs is transferred into one of the devices by means of a transfer device. After the evacuation and closing process has ended, the bag pack is re-looped back into the conveyor device during a further standstill phase of the conveyor device.
- a transfer device After the evacuation and closing process has ended, the bag pack is re-looped back into the conveyor device during a further standstill phase of the conveyor device.
- the device according to the invention for evacuating and closing bag packs with the characterizing features of claim 1 has the advantage that it has a very compact design with high performance and is relatively simple.
- the use of suction belts for evacuating the bag packs also has the particular advantage that the performance of the device can be increased almost arbitrarily in a simple manner by increasing the length of the suction belts. By a corresponding extension of the suction belts, a sufficiently long dwell time in the device for the evacuation and sealing is achieved even with a relatively high conveying speed of the bag packs.
- the high performance of the device means that even at High-performance packaging systems that produce over 100 bags per minute, a single device according to the invention is sufficient.
- the arrangement of the sealing device below the upper suction belts has the advantage that the bag packs are always sealed until the top transverse seam is formed, so that no air or oxygen flows back into a bag pack once evacuated. Furthermore, the sealing device is thereby separated from the actual evacuation device, so that the sealing device is very accessible for cleaning and maintenance work.
- FIG. 1 shows a device for evacuating and closing bag packs in a simplified front view
- FIG. 2 shows the device according to FIG. 1 in a top view
- FIG. 3 shows a section in the plane III-III of FIG. 1
- FIG. 4 shows a longitudinal section through the inlet area of the device Device
- Figure 5 shows a section in the plane VV of Figure 4.
- the device 10 shown in the figures for evacuating and closing bag packs 1 is part of a packaging system, not shown in detail.
- a bag pack 1 is formed from a respective packaging material blank, which is then filled in a filling station with a certain amount of filling material, for example coffee, whereupon the filled bag pack 1 after passing through the device 10 further treatment stations, in particular a head closing station and optionally one Labeling station is fed.
- a cyclically operated cup chain 11 with drivers 12, 13 is used, between each of which a bag pack 1 is positively received.
- a folding station 15 is provided in front of the device 10, in which the side walls of the head region 2 of the bag pack 1 are folded flat like fins, so that it is perpendicular to the shoulders of the trunk 3 Bag pack 1 protrudes.
- the device 10 has two opposite ones at the level of the head region 2 of the bag packs 1
- Each of the suction conveyors 16, 17 consists of a lower, narrow suction belt 18, 19, and an upper, wide suction belt 20, 21.
- the upper suction belts 20, 21 are longer than the lower suction belts 18, 19.
- the suction belts 18 to 21 have a common, driven deflection wheel 22, 23 reaching over the height of both suction belts 18, 20 or 19, 21, and a lower deflection wheel 24, 25 or upper deflection wheel each having the height of the corresponding suction belt 18, 19 or 20, 21 26, 27.
- the two driven deflection wheels 22, 23 are coupled to one another and driven by a common motor, not shown, so that the suction belts 18 to 21 move synchronously and at the same speed.
- the conveying speed of the suction belts 18 to 21 in turn corresponds to the conveying speed of the cup chain 11.
- the arrangement of the suction belts 18 to 21 is such that the strands of the suction belts 18 to 21 facing the two sides of the head region 2 of the bag pack 1 touch each other.
- troughs are formed at regular intervals, which are arranged such that they each form a pocket 28 for a head region 2 of a bag pack 1.
- the bags 28 are aligned centrally with the head regions 2 of the bag packs 1, and they have a smaller width than the bag packs 1.
- the troughs in the lower suction belts 18, 19 are formed over their entire height, while they are in the upper suction belts 20, 21 run only over part of their height, so that the upper suction belts 20, 21 cover the mouth of the bag pack 1 in any case.
- the height of the pockets 28 therefore corresponds at least to the height of the head region 2 of the bag packs 1.
- Through bores 29, 30 are formed in the strands of the suction belts 18 to 21, the size of the upper through bores 29 assigned to the upper suction belts 20, 21 is larger than the size of the lower through holes 30 arranged in a row. Furthermore, the upper ones
- Through bores 29 are arranged in a chamber-like region 31 of the pockets 28, which is located above the head region of a bag pack 2.
- the through bores 29, 30 interact with slot-shaped suction channels 32, 33, which in suction strips 34, 35 and
- suction strips 34 to 36 are formed.
- the suction strips 34 to 36 are each in a vacuum base 37, 38, which is arranged between the strands of the suction belts 18 to 21.
- a suction bore 39 emanating from the upper side of the vacuum base bodies 37, 38 opens, while the suction channel 33 is connected to a different suction bore 40.
- the suction bores 39, 40 are connected to at least one vacuum source, not shown.
- Bag packs 1 are arranged below the upper suction belts 20, 21 in extension of the lower suction belts 18, 19 with a sealing device 41 with sealing jaws which can be moved relative to one another. Furthermore, a compression device is located below the lower suction belts 18, 19 42 for compressing the contents in the bag packs 1.
- the compression device 42 has a base plate 43 and two side plates 44, 45, all of which can be moved against the bag packs 1.
- the device 10 described above works as follows: The filled and pre-folded in the folding station 15 in the head area 2 bag packs 1 are gradually moved from the cup chain 11 between the suction conveyors 16, 17, which also step by step and synchronously with the
- Cup chain 11 are driven. There, the head areas 2 reach the area of the pockets 28 of the suction belts 18 to 21. The walls of the head area 2 of the bag packs 1 are now sucked through the lower through bores 30, so that an opening to the inside, that is to say to the filling material in the bag packs 1, is made is trained. Through these openings, the contents of the bag packs 1 are evacuated via the upper through holes 29, i.e. the existing residual oxygen is sucked out of the bag packs 1 for the purpose of better durability of the contents. If necessary, the contents are then gassed with a protective gas. Simultaneously with the evacuation process of the bag packs 1, the filling material is compressed or compressed by the compression device 42. By compressing the filling material, air is additionally pressed out of the bag packs 1, so that the evacuation process is supported.
- the bag packs 1 pass from the area of the lower suction belts 18, 19 into the area of the sealing device 41. There, during the standstill phase of the cup chain 11, one becomes in the head area 2 Bag package 1 sealed the top cross seam 4. Since the upper suction belts 20, 21 after leaving the bag pack 1 from the area of the lower suction belts 18, 19 before the head area 4 of the bag pack 1 is sealed tightly by the sealing device 41, further operative connection with the bag pack 1 prevents air or oxygen from entering the still unsealed one Bag pack 1 returned.
- the bag pack 1 arrives at the next conveying cycle of the cup chain 11 from the area of the device 10 in order to be fed to further treatment stations.
