2.1.1.10 Pneumatic system
(references given in paragraph 2.4.1 - PNEUMATIC SYSTEM DIAGRAM)
The control unit located in the machine base monitors the pneumatic system. The air preparation elements (filters and
pressure regulators), the controls for the points of use (solenoid valve for air jets and solenoid valve that controls the
pneumatic cylinder which regulates the cap flow in the infeed channel) and the manifold for air jets are also found here.
2.1.1.11 Cooling system
(references given in paragraph 2.4.2 - COOLING SYSTEM DIAGRAM)
The purpose of the cooling system is to cool down the first bearing of the work drum. To accomplish this a solenoid
valve is provided which is monitored by a temperature control found in the electric cabinet.
2.1.1.12 Vacuum system
(references given in paragraph 2.4.3 - VACUUM SYSTEM DIAGRAM)
The vacuum system consists of a vacuum pump located under the table which holds the caps down when they are
transferred from the infeed turn-table to the spindles and vice versa.
2.1.1.13 Switchboard
(references given in chapter 6 - USE OF THE MACHINE)
The switchboard includes both a power and control section.
The power section includes all the equipment required for the electric drives (contactors, relays, etc) as well as the
devices that process the signals which come from the machine controls or keyboard (microprocessor based control
unit, motor drives, etc).
The control section is used by the operator to control and monitor the machine. The machine can be run either in
manual or automatic mode. A programmable logic controller is used and the operator can carry out the following
operations from the keyboard:
- Set the work-cycle
- Set and change the work parameters
- Display the values
2.1.1.14 Safety devices installed
The machine comes with mechanical and electric safety devices that safeguard the machine and operator during use.
In addition, the machine is equipped with fixed and mobile guards with relative interlocks. A detailed description of the
devices is given in chapter 3, SAFETY PRECAUTIONS.
