Definitions

  • the present invention relates to a device for an automatic packaging machine for clocking in to a plurality of piece goods which are fed in side by side and one behind the other in an irregular manner, with a plurality of side belts which are arranged in parallel next to one another and are separated from one another by channels and which convey the piece goods and transport stowage means which can be moved into the movement paths of the piece goods .
  • the piece goods In the area of automatic production systems for bulk goods, such as confectionery goods, the piece goods have to be controlled on their transport route and in particular in the sphere of action of the packaging machine and then transported in the correct sequence to the nesting level in a precise row.
  • Packaging machines of this type are manufactured by the applicant itself, the articles or piece goods being fed by means of, as a rule, cord conveyor belts from a production final stage to a collection or loading station.
  • the piece goods are brought in several channels, for example 24 channels, in an irregular sequence and with an irregular spacing of, for example, 30 to 100 millimeters and then, for an order in series, briefly accumulated at a linear stop.
  • This linear stop can be formed, for example, by lifting elements at the loading station of the packaging machine, as is described in detail in GB-A-2078 193, published by the same applicant, after the priority date.
  • each channel is assigned two stowage stops arranged one behind the other with the spacing of at least one piece of goods, and two light barriers, each arranged in front of a stowage stop, the stowage stops of each row being mounted next to one another on a stop bar or sections thereof and via one each Actuating electromagnets can be actuated depending on the switching state of all light barriers to carry out their alternating movement, and the light barriers of the first row in the transport direction each cause a switch-on signal or a repetition signal when a piece goods are brought in at a timing element, and the light barriers of the second row when a piece goods are presented cause a bridging signal at each jam stop of this series together on the timing element, which timing element generates an actuation signal for the electro-magnet after its time constant has elapsed or after the arrival of the bridging signal eten delivers.
  • time constant can be set on the timing element and if the timing element comprises a repeat signal and bridging signal stage.
  • the minimum time constant can also be approx. 2 seconds.
  • the packaging machine illustrated in FIG. 1 comprises an insertion station 1, which is preceded by an infeed device 2 according to the invention, which is located in the transport path of the piece goods 3.
  • an infeed device 2 according to the invention, which is located in the transport path of the piece goods 3.
  • the piece goods 3 are transported in several channels 4 next to one another by means of cord conveyor belts 5, in the direction of arrow 6.
  • the piece goods 3 arrive in the area of the loading station 1, where the piece goods 3 are combined and grouped such that they are picked up and closed by a loading head 8 with a corresponding number of suction probes 9 the actual packaging level 7 can be transported.
  • This packaging stage 7 comprises a conveyor belt 10, on which the empty boxes 11 one after the other guide belt 12 is placed by means of a further insertion head 13 and filled by means of the first-mentioned insertion head 8.
  • the insertion heads 8 and 13 are displaceably guided on cross sections 14 which are supported on the machine frame 15.
  • the insertion station 1 is supplied with as complete as possible a series of piece goods 3 in succession and within a predetermined time in order to avoid incorrect fillings as far as possible, without, however, taking the risk of a backflow in one or the other channel 4.
  • the single-stroke device 2 comprises, for each channel 4, two stowage stops 16 and 17 arranged one behind the other with the spacing of at least one piece good, which are mounted side by side on a common stop bar 18 and 19, respectively.
  • Each stop bar 18 or 19 is adjustable between a stop position and a release position by at least one electromagnet 20 or 21. Seen in the direction of transport, the stop beam 18 carries the first row 16 of the traffic jam stops and the stop bar 19 accordingly carries the second row 17 of the traffic jam stops. It should be mentioned here that the same effect is achieved if the stop bars are divided into sections with their own electromagnets or each backstop has its own electromagnet, which is a question of reasonable expenditure.
  • FIG. 3 also shows that two light barriers 30 and 31 are provided per channel 4, each arranged in front of one of the accumulation stops 16 and 17. These light barriers 30 and 31 are all connected together to a timing element 25, the output signal 27 of which supplies an actuation signal for the control circuit 26 of the electromagnets 20 and 21.
  • the timing element 25, which preferably comprises a repetition signal stage and a bridging signal stage (not shown in more detail), is of a suitable known design and thus does not require any detailed explanation.
  • the circuit arrangement is such that the light barriers 30 in front of said first row 16, 18 of the traffic jam stops 16 each have a switch-on signal or a respective arrival at the arrival of a general cargo 3 at the relevant traffic jam stop 16 of a channel 4 on the timing element 25 cause a repetition signal with which a time constant, which is expediently controllable and can be, for example, 2 seconds, is switched on or switched back and on again.
  • the circuit arrangement of the timing element 25 is such that the light barriers 31 on the second row 17, 19 produce a bridging signal together with the timing element 25 on presentation of a piece 3 at each accumulation stop 17 of this row.
  • the timing element 25 can supply an actuation signal 27 to the control circuit 26 of the electromagnets 20 and 21 either after the time constant not interrupted by a repetition signal has expired or after the arrival of the bridging signal.
