Abstract

A packaging installation, in which two twin dispensing machines feed a high-capacity packaging machine, has a plurality of providing devices (25 to 28) and transfer devices (30, 31) for the articles to be packaged, for example bag packs (p). In order to be able to operate in each case several, for example two, providing devices (25 to 28) with one transfer device (30, 31) and in order to ensure that in each case only one bag pack (p) is deposited into the buckets (19) of the conveying device (15) of the packaging machine, the providing devices (25, 26; 27, 28) assigned in each case to a transfer device (30, 31), and the carriers (36) of a transfer device are spaced apart by a distance which is smaller three dividing than the length of a predetermined group of the buckets (19) of the conveying device (15) e.g. the carriers are spaced by the distance dividing three buckets for every group of four buckets. Furthermore, the transfer devices are driven in such a way that their carriers (36) strike gently against a bag pack (p) already provided on the providing devices, then are accelerated up to the conveying speed of the conveying device (15) in such a way that the bag packs are delivered synchronously into the buckets (19) of the conveying device (15), and subsequently are slowed down again. <IMAGE>

Description

is Apparatus for transferring articles into a,conveying device of a
packaging machine
Prior Art
The invention is based on an apparatus for transferring articles into a conveying device of a packaging machine, of the type described in Claim 1.
In a packaging installation in which a plurality of dispensing machines, for example bag-packing or wrapping machines, feed a high-capacity packaging machine, for example a cartoning machine, the output of which exceeds that of a dispensing machine manyfold, a plurality of providing devices are assigned to the product-conveying device of the packaging machine, which providing devices in each case simultaneously provide one or more articles to be packaged which have been produced by the dispensing machines and which then are brought by transfer devices having carriers into the buckets of the continuously running product-conveying device of the packaging machine at the same speed. The drives of the transfer devices are coupled to that of the conveying device in such a way that a transfer device in each case supplies the same bucket of a group of successive buckets of the conveying device, the number of the buckets of a group being equal to the number of the transfer devices.
A packaging installation of this type, disclosed for example in US Patent Specification 4,,178,,120,, has three transfer devices arranged one behind the other, to which two providing devices are in each case assigned and which supply in each case into [sic) the same bucket of the buckets, divided into groups of three, of the conveying device with two times two articles. For this purpose, the distance between the carriers of a transfer device is equal to the division of the buckets of the conveying device into threes and equal to the dividing distance between a group of three buckets of the conveying device, and the conveying speed of the transfer devices is equal to the conveying speed of the conveying device of the packaging machine. In the known installation. it is not possible to apportion the articles provided in the two providing devices of a transfer device into differently arranged buckets of the groups. or to bring in each case only one article into the buckets of the conveying device.
US Patent Specification 4,854.440 discloses furthermore a packaging installation having four transfer devices to which in each case only one providing device is assigned and of which in each case the same transfer device feeds the in each case identically arranged bucket of a group of four buckets of the conveying device with an article. The transfer devices have high-dynamic drive motors via which it is possible to control a gentle striking against the provided articles and a delivery of the same at an appropriate time into the buckets of the conveying device.
Advantages of the Invention

Claims (4)

  1. The apparatus according to the invention for transferring articles into
    buckets of a productconveying device of a packaging machine according to Claim 1 has the advantage that. using a small number of transfer devices, articles provided on a plurality of providing devices are delivered, apportioned individually to the successive buckets of the conveying device, at a high capacity. By virtue of this arrangement, the structural length of the packaging machine can be shortened and its installation space reduced. Furthermore, the number of drives is small and their control is simplified.
    An apparatus for transferring articles, designed according to Claim 2, is particularly advantageous if both-of its transfer devices are connected to so-called twin dispensing machines which generate two articles, for example tubular bag packs. in each cycle.
    is Drawing The transfer apparatus according to the invention is depicted in the drawing and is described in more detail below. Figure 1 shows a packaging installation with two twin dispensing machines and part of a packaging machine with a product-conveying device in a simplified plan view, and Figures
  2. 2 and 3 show part of the packaging installation according to Figure 1 in a highly simplified side view in various working positions.
    Description of the Illustrative Embodiment In the packaging installation depicted, two twin dispensing machines, for example two twin tubular bagshaping, -filling and -sealing machines 11, 12, which each produce and dispense two tubular bag packs p in each cycle, are assigned to the product-conveying device 15 of a packaging machine 16 which packages the bag packs p one after another into folding boxes.
    The conveying device 15 has an endless conveying chain 17 to which Ushaped product buckets 19 are fastened at uniform distances. The conveying device 15 is driven at a uniform speed. In order to feed the buckets 19 of the conveying device 15 with bag packs p generated by the tubular bag-packing machines 11. 12. two pairs of conveyor belts 21, 22 and 23. 24 are arranged between the bag-packing machines 11. 12 and the conveying device 15, running transversely to the conveying direction 15. A table 25, 26 and 27, 28, onto which in each case one bag pack p is provided f or transfer into a bucket 19,, is arranged in each case at the ends of the conveyor belts facing the conveying device 15, just above the conveying path of the conveying buckets 19 of the conveying device 15.
    Above in each case two tables 25, 26 and 27. 28 respectively, assigned to a tubular bag-packing machine 11 and 12 respectively. a transfer device 30, 31 is in each case arranged which periodically transfers the bag packs p provided in each case on the tables 25 to 28 into the buckets 19 of the conveying device 15. and to be more precise in each case one single bag pack into one bucket 19. Each of the transfer devices 30, 31, which are of identical construction, has an endless conveying chain 32 which is guided around two deflecting wheels 33, 34 and whose lower straight section 35 runs parallel to and above the conveying path of the conveying device 15. The conveying chain 32 is driven by a high-dynamic electromotor 38 via a toothed belt 37.
    Four outwardly projecting carriers 36 are arranged at uniform distances on each conveying chain 32. The distance between the individual carriers 36 of a conveying chain 32 is equal to the distance between the two tables 25, 26 and 27, 28 respectively assigned to a transfer device 30.. 31. The distance between the two tables 25, 26 and 27, 28 respectively assigned in each case to one transfer device 30, 31 is less or greater than the distance between four successive buckets 19, forming a group, of the conveying device 15, in such a way that the bag packs p transferred by a transfer device 30, 31 into the buckets 19 of the conveying device 15 do not pass into a single bucket 19, and that a double supply is thus avoided.
    Since, in an arrangement consisting of fou2 providing tables 25, 26 and 27, 28, in each case four bag packs are to-be transferred into the conveying device 15 and in each case only one bag pack p is to be introduced into a bucket 19, in each case every fourth successive bucket 19 of the conveying device 15 is supplied with a bag pack p from each table 25 to 28, and to be precise the first bucket 19 of each group of four from the table 25, the second bucket from the table 28. the third from the table 27 and the fourth bucket from the table 26, two adjacent buckets 19 in each case being fed by the same transfer device 30 or 31. In order to achieve this, the distance between the two tables 26, 27 [sic] and.27,, 28 respectively assigned in each case to a transfer device or 31 amounts to three dividing distances between the buckets 19 of the conveying device 15, and the distance between each of the carriers 36 of each conveying chain 32 likewise amounts to three dividing distances between the buckets 19 of the conveying device 15. Furthermore, the distance between the two adjacent tables 26 and 27 as.signed to different transfer devices 30, 31 amounts to seven dividing distances between the buckets 19 of the conveying device 15. This distance has been chosen so that access is possible for the operator between the two bag-packing machines 11, 12, the conveyor belts 22 and 23 and the transfer devices 30. 31. The distance between in each case adjacent transfer devices is per se not linked is to the dividing up of the conveying device, but it should be sufficiently large to correspond approximately to the distances between the dispensing machines.
    As already mentioned, in order to supply in each case one bucket 19 of the conveying device 15 with only one bag pack p, the conveying chains 32 of the transfer devices 30, 31 are driven in such a way that, during the time which it takes for the conveying device 15 to move at a uniform speed in the direction of arrow c by four bucket divisions towards the packaging machine, the conveying chains 32 have been driven forward in the same direction by only three dividing distances between the buckets 19 of the conveying device 15. The drive of the conveying chains 32 is preferably controlled in such a way that the carriers 36 run up against the bag packs p provided on the tables 25 to 28 at a slow speed, then are accelerated so that the bag packs p have the same speed as the buckets 19 running beneath them when they slip off the table 25 to 28 (Figure 3), and that the movement of the conveying chains 32 is slowed down again after the uniform-speed delivery. A drive for such a fluctuating speed v is designed in such a way that, during the abovementioned period, during the time it takes for the buckets 19 of the conveying device 15 to cover a distance of four bucket divisions, the carriers 36 of the conveying chains 32 have travelled a distance of only three bucket divisions on the straight section 35 parallel to the conveying device 15. A control of this type is possible'using high-dynamic electromotors 38 for the transfer devices 30. 31 and using a processcontrol computer which adjusts the running of the two bag-packing machines 11, 12 as a function of the running of the packaging machine 16, and controls the electromotors 38 of the transfer devices 30, 31 in the above-described manner.
    The packaging installation described above functions as follows:
    The two twin tubular bag-packing machines 11, 12 produce in each cycle two bag packs p which are conveyed by the conveyor belts 21 to 24 onto the providing tables 25 to 28. The carriers 36 of the conveying chains 32 of the two transfer devices 30, 31 strike against the bag packs p arranged there at a low speed and carry them along (Figure 2). Directly after the bag packs p have been pushed off by the carriers 36, the conveying chains 32 are accelerated to a speed which corresponds to that of the'conveying chain 17 with the buckets 19,, so that the bag packs p at the end of the tables 25 to 28 are released synchronously and covering in each case one bucket 19 of the conveying device 15, and fall into these buckets (Figure 3). The speed v of the conveying chains 32 of the transfer device 30, 31 is then slowed down again so that the carriers 36 fall back with respect to the buckets 19 of the conveying device 15. The length of the distance by which the carriers 36 are behind with respect to the buckets 19 amounts to one dividing distance between the buckets 19 of the conveying device 15, so that the carriers 36 which have just transferred a bag pack p from the left-hand tables 26, 28 of each transfer device 30, 31, after travelling three dividing distances, deposit into the buckets 19 of the conveying device 15 the bag packs p which have been provided again in the meantime on the adjacent tables 25, 27 arranged downstream in the conveying direction, which buckets follow 1 A1 is the buckets 19 supplied beforehand directly in the conveying direction. In this way, in each case four buckets 19 of the conveying device 15 are supplied with bag packs, whereas always the bucket 19 having the same arrangement in a group of four buckets 19 arranged one behind the other is supplied from each table 25 to 28.
    The transfer apparatus according to the invention can also be expanded so that three or four twin dispensing machines are assigned to the productconveying device of a packaging machine. One transfer device, with in each case one conveyor and two providing devices as in the above- described il lustrative embodiment, is here in each case assigned to one dispensing machine. In an arrangement in threes, the conveyors are controlled in such a way that the first conveyor coats [sic] the third and sixth bucket with an article, the second conveyor the second and fifth bucket, and the third conveyor the first and third bucket of a group of six successive buckets. In a similar mannero, in an arrangement in fours of twin dispensing machines, the first conveyor feeds the third and eighth bucket, the second conveyor the first and sixth bucket, the third conveyor the seventh and fourth bucket, and the fourth conveyor the fifth and second bucket of a group of eight successive buckets. The speed of the conveyors is correspondingly adapted in such a way that the delivery of the articles into the buckets takes place synchronously, and that the conveyor is subsequently driven at a reduced speed and, finally. accelerated again up to its delivery speed in order to transfer an article.
    It should, in addition, be noted that in order to transfer in each case four bag packs. a single transfer device with an endless conveying chain and eight [lacuna] thereon spaced apart by in each case three dividing distances between the buckets of the conveying device is also possible, to which four providing tables are assigned likewise spaced apart in each case by a distance of three dividing distances, and which is driven as described above.
