7.2 Machine type

Here, the type of system is determined, which corresponds to the position and mode of

operation of the device thus required in the production line.

The following types of machine are defined for the Productivity Lift:

Input module : If the lift is at the beginning of the Siplace assembly line, this setting must be

selected in machine type. The input module can only transfer printed circuit

boards on transport tracks 1 and 2. Priority is given to attempting to then

transfer the PCBs to the placement machine. If this is not possible, the

unassembled PCBs are forwarded essentially to track 3 on the lower level

and then transported for the time being to the next lift (intermediate module)

or the placement machine.

Cluster module : The intermediate module is located after the input module and is defined as

the intermediate module as long as the subsequent placement machines are

of the same type. The intermediate module accepts either assembled PCBs

from tracks 1, 2 and 4, and transfers them further on track 4, or it accepts

unassembled PCBs from track 3 and attempts to deposit them at the

following placement machine. If the following placement machine is

occupied, the unassembled PCBs are transported further via track 3 to the

next lift or placement machine.

Allocation of the inlets and outlets to each other:

- take-over inlet track 1 → hand-over outlet track 4

- take-over inlet track 2 → hand-over outlet track 4

- take-over inlet track 3 → hand-over outlet track 1, 2 or 3

- take-over inlet track 4 → hand-over outlet track 4

In order to prevent the system becoming blocked, only one PCB may be

transferred if the allocated outlet is ready. Fixed priorities are allocated to the

individual transport directions. Inlet tracks 1 and 2 as well as outlet tracks 1

and 2 all have the same priority.

Otherwise the following applies:

1. take-over inlet track 3 → hand-over outlet tracks 1 and 2

2. take-over inlet tracks 1 and 2 → hand-over outlet track 4

3. take-over inlet track 3 → hand-over outlet track 3

4. take-over inlet track 4 → hand-over outlet track 4

Cross module : The setting cross module must always be selected if the type of placement

machine changes in the line. The cross module handles all incoming PCBs

as if they are unassembled. In this way, the PCBs arriving on tracks 1, 2 and

4 are presented to the placement machine for processing. If the following

placement machine is of the same type, PCBs can also be transferred on

track 3 at the cross module if the current placement machine is occupied. If

the cross module is the last lift before the final module, no PCBs may be

transferred on track 3. Similarly, no PCBs may be accepted from the last

intermediate module before this cross module.

Convert 4→2 : Convert module from 4 tracks to 2 tracks, whereby 4 tracks indicate the

lower and upper two tracks.

Application:

A suitable device should be used to break up a long placement line to allow

access for people, for example. This reduces the transport tracks to 2 tracks,

since a device can not have two tracks on the lower transport level. With the

convert module 4→2, PCB transport is reduced to 2 tracks, separated

according to assembled and unassembled PCBs.

Convert 2→4 : Convert module from 4 tracks to 2 tracks, whereby 4 tracks indicate the

lower and upper two tracks.

Application:

A suitable device should be used to break up a long placement line to allow

access for people, for example. This reduces the transport tracks to 2 tracks,

since a device can not have two tracks on the lower transport level. With the

convert module 2→4, PCB transport is increased again to 4 tracks,

separated according to assembled and unassembled PCBs, following this

type of interruption.

Output module : The final module is defined as the last lift in the direction of transit, after the

Siplace systems. Essentially, the final module has no lower belt. If the lift is

implemented as the final module, the abovementioned system types can not

be selected. The PCBs are transferred from tracks 1, 2 and 4. Transfer to

tracks 1 and 2 has priority. The printed circuit boards can only be delivered

at the final module via outlet tracks 1 and 2. No PCBs can be transferred

from track 3 or transported further on this track.

7.3 Ramp up mode / Ramp down mode

7.3.1 Example of Cluster with three Siplace units

7.3.2 Ramp up mode

PCB distribution parameter, which defines the loading sequence of the PCBs within a cluster

of Siplace units. The value of x depends on the number of Siplace units within a cluster (see

example 7.3.1).

The menu allows to set the value x between 0...9 .
