  • a reduction in the transmission power leads only slowly to a reduction in compressed air, since first arrive the article in the pipe 17 in the receiver unit 14 must and the pressure level in the pipe 17 degrades only slowly. If the control unit 20 can not produce the launch speed for the requested transmit power, the transmit power will remain at the highest possible value to continue operating smoothly.
  • the (initial) venting element 19, 28 and the (end) venting element 22 are controlled by the transmitter unit 11 via an interface module 23 which is in two-sided communication connection with the transmitter unit 11, the receiver unit 14 and the control and regulation unit 20 and / or regulated.
  • the interface module 23 virtually realizes the communication between the transmitter unit 11 and the receiver unit 14.
  • the information must be interpreted and processed. This is the purpose of the already mentioned communication protocol, also called protocol for short.
  • protocol for short The following is the operation of the communication protocol based on the FIG. 3 described in more detail.
  • the communication between a transmitter unit 11 and a receiver unit 14 or more precisely between the control unit 12 of a transmitter unit 11 and the control unit 15 of a receiver unit 14 is realized via a cable, via which so far only a filter request signal is sent from the receiver unit 14 to the transmitter unit 11, which is switched on and off accordingly.
  • a cable via which so far only a filter request signal is sent from the receiver unit 14 to the transmitter unit 11, which is switched on and off accordingly.
  • the inventive compressed air control for the transport of the filter rods it is necessary to transfer additional data.
  • the communication protocol according to the invention has been developed. With this communication protocol, it is now possible to transmit numerical values, status and control bits without installing additional lines or implementing an additional bus connection.
  • transmitter units 11 and / or receiver units 14 of a new generation it is thus possible to supplement existing systems with additional transmitter units 11 and / or receiver units 14 of a new generation so that they can be operated in conjunction with transmitter units 11 and / or receiver units 14 of an older generation, since version recognition and backward compatibility are ensured.
  • a communication user for example the transmitter unit 11, starts by means of its control device 12 to output regular clocks. With each clock, the other communication subscriber sends a bit information to the clock. When the information of one record or information unit has been completely transferred, the clock changes and the other communication subscriber gets the opportunity to send information. The individual bit information is interpreted and processed accordingly. The clock constantly changes back and forth. Even if a communication participant has no data to send, we will inform the other person. A once established connection remains in permanent contact until it is physically disconnected.
  • a transmission unit consists of a function number, from which the subsequent data length is determined, the data and a checksum. If this transmission unit has been transmitted, the clock changes. In case of an error in the transmission, the information is discarded. There are the function numbers 0, 1, 2, ........ 15, with the first and last function numbers reserved for the protocol. After the function number has been transmitted, the data receiver knows how long the subsequent data is in bits. This information has previously been specified in a program of the program block. The received checksum is compared with the self-calculated checksum. In the event of an error, the information is discarded and subsequently the error is communicated to the information sender via function 0. This can then repeat the transmission.
  • ppm article per min.
  • each pipe 17 must send 1000 ppm.
  • the compressed air flow as well as the initial vent and the end vent are controlled and / or regulated.
  • the transmission power is adjusted automatically for each transmitter module 13 and between the multiple transmitter modules 13.
  • a pipe 17 can not send, controls and / or regulates the control unit 20, the two other transmitter modules 13 such that they with an increased transmission power of 1500ppm send, so that the receiver unit 14 are unchanged at 3000ppm available.
  • the compressed air flow is increased.
  • the transmission power is redistributed and the compressed air flow in the individual pipes 17 can be reduced again. This adjustment takes place via the proportional valves 21 automatically, so that an energy-efficient and the article gentle operation is guaranteed.
  • the communication connection is based on a communication protocol, which is designed with two channels.
  • a first communication station sends a uniform pulse train on a first line to a second communication station.
  • the second communication user simultaneously sends user data on a second line to the first communication user.
