3 6.1 - ESSENTIAL PARAMETER PROGRAMMING TO ALLOW MACHINE OPERATION The following screen appears on connection to the electrical power supply: indicating the program version of the machine. Shortly afterwards the main screen appears: This page gives access to different machine options PROGRAMMING OF TEMPERATURE PARAMETERS By pressing this key: the following screen will appear: : 2

4 By using the cursor keys ( )( ) to move around the page it is possible to select the field that we wish to modify. By using the cursor keys ( )( ) we ca move to the next programming page. The selected field will be highlighted on a white background with black letters. Once the required field is selected, we can introduce the new value, after which the (M) key is pressed to validate the entered data. Once all data has been entered in this way, pressing the escape key (ESC) will save the data to the non volatile memory (EEPROM). Whilst data is being saved, the following screen is displayed: : 3

5 DESCRIPTION OF PARAMETERS. The temperature value is programmed according to the required working temperature for each zone. Changing this parameter programs the time interval between temperature conversions. When this value is missing there is a proportional resistance connection, the greater the difference between actual and programmed temperature, the greater the duration of the resistance connection. When the difference between actual and programmed temperature is lower, the shorter is the duration of the resistance connection The proportional duration of connection/disconnection of resistor is shared with respect to the previously programmed temperature reading interval, If the temperature reaches a value within the margins (programmed zone - deviation alarm margin) and (programmed zone + deviation alarm margin) the out of range temperature alarm is not triggered. NOTE: Once the electrical supply is connected the heating process is initiated progressively for several minutes in order to protect the resistance units : 4

6 TIMINGS PROGRAMMING. By pressing this key: the following screen will appear: By using the cursor keys ( )( ) we can move around the page to select the field that we wish to modify. The selected field will be highlighted with black letters on a white background. Once the required field is selected, we can introduce the new value, after which the (M) key is pressed to validate the entered data. Once all data has been entered in this way, pressing the escape key (ESC) will save the data to the non volatile memory (EEPROM). Whilst data is being saved the following screen is displayed: : 5

7 DESCRIPTION OF TIMINGS. It is necessary to program the bag length (mm) we wish to produce. (This value must be programmed with any of the measuring modes selected) When working in SPOT mode the film dosing motor will stop when the corresponding SPOT on the film is detected. Letters and drawings that may be printed on the film may confuse the SPOT detector, thereby provoking a false stoppage. We program this value in order to avoid this problem, so that the SPOT detection is disabled until the SPOT is approached, the SPOT zone being identifiable as a function of bag length (For example: Bag length 450mm, Length before SPOT 20mm, indicates that detection will not be activated until bag travel exceeds 430mm (450-20). (This timing only applies to the SPOT dosing modes) This value comes into play when the length of film fed is equivalent to the theoretical length but without the SPOT having been detected. Once the length programmed here has been fed without the SPOT having been detected, the motor will be stopped. (This timing only applies to the SPOT dosing modes) When the input conveyor has stopped thus indicating that a packet has been sent, this timing is activated and allows time for the product to fall completely into the bag. Once this time has passed the bag is considered to have finished charging with product. This timer initiates when a signal from the weigh cell is received thus indicating that a packet has been sent. On completion of this time the input conveyor receives a signal to indicate that the packet is on the conveyor. This feature is employed when the machine is connected to a weighing cell that is shared with another packaging machine that requires a shorter TIME than the "48", in which case we increase the TIME to coincide with that of the "48" : 6

8 These timings allow the exit conveyor vibration times to be programmed. This timer is connected when the transfer process is initiated. When this time is completed the input conveyor is connected (If there is product on the conveyor) PROGRAMMING OF WORKING PARAMETERS. By pressing the (M) key different options. The cursor keys are activated we gain access to the programming section for the allowing access to the options. By using the keys we can select the parameters that we wish to modify. By using the keys we modify the option. To exit the working parameter programming mode, press the (M) key again. On initiating the process the following screen will appear: The "STATIC WELDING" indicator appears, which is the default option. This parameter cannot be modified from this point. It can only be modified in machine configuration given that such changes also imply a considerable amount of mechanical modification : 7

9 EXIT CONVEYOR SELECTION By pressing the right cursor key the following indication appears: In this case we select that the exit conveyor rises and vibrates. By using the up & down cursor keys the rest of the options can be chosen. In this case we chose that the exit conveyor rises and SHALL NOT vibrate. In this case the exit conveyor is not selected ELEVATING PLATFORM SELECTION PROCESS By pressing the right cursor key the following indication appears: In this case we select the elevating platform option. By using the up & down cursor keys, the rest of the options can be chosen : 8

10 In this case the elevating platform option is NOT selected HANDLE / DIE SELECTION PROCESS By pressing the right cursor key the following indication appears: In this case the option YES HANDLE is selected. By using the up & down cursor keys the rest of the options can be selected. The following screen will appear first: A password is required to make changes given that this selection depends on a mechanical implementation, thereby avoiding accidental changes. The password is: Once the password is entered, the following screen appears: In this case the DIE option is selected : 9

11 In this case the NO HANDLE and NO DIE modes are selected HEATING SELECTION. By pressing the right cursor key, the following indication appears: In this case indicating that the heating is activated. By using the up & down cursor keys, the rest of the options can be selected. In this case, the screen tells that the heating is shut-off FILM DOSING MODE SELECTION. By pressing the right cursor key, the following indication appears: In this case indicating that FILM dosing will be by length. When selected the BY LENGTH mode the FILM will be fed for long enough to reach the defined FILM length. When a FILM length is defined, the corresponding dosing motor running time is calculated so that the correct length is metered out. By using the up & down cursor keys the rest of the options can be chosen : 10

12 In this case, the screen tells that FILM dosing will be by ONE SPOT If the ONE SPOT mode is selected, then by definition we will be using film that has regularly spaced black reference spots so that when the detector sees a SPOT, the FILM dosing motor stops. In this case the screen informs that FILM dosing will be by TWO SPOTS. Selecting the TWO SPOT mode, by definition we are working with two FILM bands that will carry black reference spots at regular intervals. In this mode therefore, by means of energising and deenergising the brakes, an adjustment is aimed so that both SPOTS coincide OPERATION WITH A LABELLER. By pressing the right cursor key the following indication appears on the screen if a labeller has been configured: In this case the adhesive label option is selected. By using the up & down cursor keys the rest of the options can be chosen. In this case the adhesive label option has NOT been selected. If the TRANSFER labeller is selected, the following signs appear: : 11

13 TRANSFER label selected. TRANSFER label NOT selected. When we have selected the labeller, an order can be given to make a label by pressing the [F3] key. Whilst the label is being produced the following indication appears: PHASE MEMORY ERASURE. By pressing the right cursor key, the following indication appears; indicating that we are in the phase memory erasure option. By using the up & down cursor keys, phase erasure can be selected; allowing us to confirm whether or not we wish to erase these memories. This could be necessary for the following reason: When the machine is operating, it records in the memories every time a phase is finished, so that if we stop the process and then re-start it the activated phases are considered to have been completed and the machine will not operate these phases : 12

14 If for some reason on stopping the process the bag is removed from one or more of the phases, if operation is resumed, the memorised phases will not be carried out although in fact they have not been completed. For this reason, if one bag is removed from one of the phases it is recommended that all bags be removed from the remaining phases and then the phase memories be erased WORKING MODE SELECTION. By pressing the key: the automatic operation mode is selected. When the automatic operation mode is selected, the indicator will appear in the upper right of the screen indicating that there is an automatic communication with the weighing cell. If the AUTOMATIC indicator does not appear, the input request to the weighing cell will be manual, by pressing the key TEMPERATURE ZONE DISPLAY. By pressing the (F1) key it is possible to see the assignation of the different zones of the CB-48 by the display of the following screen: The distribution of the machine thermocouples is indicated To exit this page, press any key : 13

15 The programmed temperatures will appear on the screen together with the actual temperature readings upon initiating heating control. Whilst the temperature is below the programmed temperature less the A deviation alarm the following indication appears: indicating the zones that are out of range. (Please note: Zone 7 is not shown to be out of range, due to the fact that this zone only operates when the DIE mode is selected) The following screen appears when the zones reach the programmed temperature: indicating that machine operation may commence : 14

47 6.8 - OPERATIONAL TIMINGS PROGRAMMING. (AUTHORIZED PERSONNEL ONLY! INCORRECT PROGRAMMING OF THESE PARAMETERS COULD CAUSE POOR MACHINE OPERATION OR FAILURE. On pressing the following key sequence (C)(4)(6)(0) from the main page the following screen will appear: By using the cursor keys ( )( ) the field we wish to modify may be selected. The selected field will be highlighted with white letters on a black background. Once the desired field has been selected the new value may be introduced and by pressing the (M) key entered and validated. By using the keys ( )( ) we can move to the page stating the timings to be modified TIMINGS DESCRIPTION. When the phase 1 welding unit is closed this timer starts running. Once the programmed time interval has passed the welding unit is disconnected. When the instruction is given to initiate the FILM process this timer starts running. Once the programmed time interval has passed the FILM motor is connected and : 46

48 the process commences. When working in FILM dosing by SPOT detection mode, this timer starts running when the detector sees the SPOT. Once the programmed time interval has passed the FILM dosing motor is disconnected. This timer starts running when the suction pads in phase 2 are in the up position. Once the programmed time interval has passed the grippers are disconnected. When a pack is requested from the input conveyor belt, and there is a pack on the belt, the conveyor belt starts and this timer starts to run. Once the programmed time interval has passed the conveyor belt motor is disconnected. When the input belt is started, a timer with the (T-05)-(T-08) value is started. Once the programmed time interval has passed a pack is requested from the weigh cell. (Therefore, when there is only the time programmed in T-8 to go for belt disconnection, a pack is required from the weigh cell). When the phase 4 clamp is closed this timer starts to run. Once the programmed time interval has passed the clamp is disconnected (phase 4 welding time) When phase 4 commences, this timer is started. Once the programmed time interval has passed, an instruction is given to bring in the air nozzles When the nozzles are in the forward position in phase 4, this timer is started. Once the programmed time interval has passed, an instruction is given to connect the : 47

49 clamp. When the sword (cutting bar) disconnection instruction is given in phase 5, this timer starts to run. When the programmed time interval has passed an instruction is given to connect the clamp. (To avoid the possibility that clamp A hooks up on the sword (cutting bar) When the instruction is given to connect the phase 5 clamp, this timer is started. When the programmed time interval has passed the clamp is disconnected. When bag transfer commences, this timer is started. When the programmed time interval has passed, an instruction is given to initiate the FILM dispensing process in phase 1. When bag transfer commences, this timer is started. When the programmed time interval has passed, an instruction is given to connect the sword (cutting bar) (If there is a HANDLE prepared, otherwise the machine will wait). When bag transfer commences, this timer is started. When the programmed time interval has passed, an instruction is given to connect the elevating platform. When the transfer motor disconnects, this timer is started. When the programmed time interval has passed, the transfer finish is indicated and therefore all the phases are enabled to start operation : 48

50 This is so as to avoid movement of the different phase mechanisms, before the transfer has stopped completely (due to the effects of inertia). When the product input belt connects, this timer starts. When the programmed time interval has passed the elevator is deenergized and the output belt vibrator is started (if this option has been selected). When the transfer initiates, this timer is started. When the programmed time interval has passed, the phase 1 belts open and the phase 1 film extraction delay is initiated. When the suction pads reach the down position, this timer is started. When the programmed time interval has passed, the venturi is switched on. When the instruction is given to stop the film dosing motor, this timer is started. When the programmed time interval has passed, an instruction is given to close the phase 1 belts. When the transfer is switched on this timer is started. When the programmed time interval has passed, bag blowing in transfer starts. When the programmed time interval (T-29) has passed and bag blowing is switched on this timer is started. When the programmed time interval has passed bag blowing is disconnected. When the transfer is switched on this timer is started. When the programmed time interval has passed, the net (mesh) placer mechanism in transfer is switched on.
