Definitions
- the invention relates to the field of vacuum pumps.
- the invention relates to a vacuum pump with an integrated control.
- Vacuum pumps such as rotary vane pumps or screw pumps have three-phase motors as a drive and their start-up control is realized via an electrical circuit by means of contactors in a control box. Valves provided between the vacuum pump and the tool to be evacuated in packaging machines are operated by control of the packaging machine. Information about processes, errors or necessary maintenance of the vacuum pump is not available.
- a vacuum pump according to the invention for a packaging machine comprises an electric motor, a pressure generator unit and a housing.
- the vacuum pump is characterized in that a control is provided in or on the housing of the vacuum pump.
- the suitability for use in a packaging machine has the vacuum pump, in particular, if it is able to evacuate the volume of typical sealing or molding tools such packaging machines within seconds of normal pressure to a vacuum of, for example 10mbar or even 5mbar.
- the control in the housing of the vacuum pump
- the control is located in that part of the housing of the vacuum pump which surrounds at least the pressure generating unit and optionally also the electric motor, alternatively the control may be provided "on the housing of the vacuum pump”;
- the controller may be connected, for example in the form of a (terminal) box with the outside of the housing of the vacuum pump.
- the controller is preferably designed at least as a start-up control and / or circuit of the electric motor.
- the controller is connected via a bus line for data transfer with a machine control of the packaging machine, both to be able to control the electric motor by means of the machine control or a separate button on a control panel and also to transfer data from the control of the vacuum pump to a machine control to this data to view or evaluate.
- the bus line preferably data for diagnosis and / or maintenance to the machine control can be transmitted, wherein the data measured values of at least one sensor include, for example, the engine temperature or oil level, which was previously read on a sight glass on the housing or was to control ,
- the vacuum pump has at least one sensor, preferably a vibration sensor, an oil level sensor, a temperature sensor, a flow sensor and / or a vacuum sensor.
- a vibration sensor preferably a vibration sensor, an oil level sensor, a temperature sensor, a flow sensor and / or a vacuum sensor.
- the controller has a frequency control for the electric motor, which is designed as a three-phase motor, or the controller has a servo control for the electric motor, wherein this is designed as a servomotor.
- energy is saved by the speed of the electric motor is reduced when no vacuum requirement exists and would possibly be evacuated against a closed valve.
- the power can also be adapted to the need for an evacuation process by means of the speed change in order to increase the evacuation performance.
- the controller is preferably connectable to at least one valve to switch the valve by means of the controller.
- a shut-off valve is provided in particular on a suction side of the vacuum pump. This is particularly advantageous in carrying out a gassing operation in a thermoforming packaging machine by means of pure oxygen, to prevent the suction of pure oxygen into the pressure generator unit, since there would be the danger of an explosion. With this design, a cost-intensive special design of such a vacuum pump can be dispensed with.
- An embodiment as an electrically operable valve allows a packaging machine with a vacuum pump that requires no compressed air and only has an electrical supply.
- the vacuum pump according to the invention is preferably a screw pump or a rotary vane pump.
- Figure 1 a schematic representation of a thermoforming packaging machine and a vacuum pump according to the invention.
- thermoforming packaging machine 1 shows a schematically illustrated packaging machine in the form of a thermoforming packaging machine 1 with a control cabinet 2 and a machine control 3, the machine control 3 comprising a display and input device 4 and a start button 5.
- the thermoforming packaging machine 1 has a forming station 6 with a molding tool 7 to deep draw a film web. It also includes a sealing station 8 with a sealing tool 9 to evacuate and / or aerate the interior of a deep-drawn product-filled well before sealing a lid sheet onto the wells to produce an airtight package.
- a thermoforming packaging machine of this type is disclosed for example in DE 10 2010 019 634 B3.
- Fig. 1 also shows schematically (and considerably enlarged in relation to the packaging machine 1) a vacuum pump 10 according to the invention, preferably a screw pump or rotary vane pump, which comprises an electric motor 1 1 as a drive for a pressure generator unit 12.
- the electric motor 1 1 can also be designed as a three-phase motor or servomotor and the pressure generator unit 12 generates a negative pressure at a suction side 13 of the vacuum pump 10.
- the vacuum pump 10 has a housing 14 in which a controller 15 is provided, and the controller 15 is connected to the engine controller 3 via a bus line 16. Via this bus line 16 data and control commands between the controllers 3, 15 can be transmitted.
- a power line 30 supplies the controller 15 with at least the electrical energy that is provided for the operation of the electric motor 1 1.
- the power line 16 may also be provided for the supply of a processor and switching elements in the controller 15.
- the controller 15 is connected by means of at least one control line 17 to a valve 18 on the suction side 13 of the vacuum pump 10.
- the valve 18 may be disposed within the housing 14 or on the housing 14 on the suction side 13.
- the valve 18 may be provided as a shut-off valve.
- the valve 18 may include a servomotor 19, which is connected via the controller 15 by means of a control line 20, and operated to produce different cross sections in a vacuum line 21 can.
- the vacuum line 21 connects the vacuum pump 10 with the sealing tool 9 and / or with the molding tool 7.
- the vacuum pump 10 has an oil level sensor 22 which is connected to the controller 15 to detect and evaluate the current oil level or below an assumed oil level of a ⁇ lbads the pressure generator unit 12 of the controller 15 and, if necessary, a message to the machine control 3, which is displayed on the display device 4 to the operator of the packaging machine 1.
- a vacuum sensor 24 or a flow sensor 25 may be provided on the suction side 13 in order to be able to process the detected measured values in the controller 15 for controlling or controlling the electric motor 11 and / or the valve 18. In order to save energy and to reduce the load on both the electric motor 1 1 and the pressure generator unit 12, controls the controller 15, the speed of the electric motor 1 1 corresponding to the running in the packaging machine 1 processes.
- a temperature sensor 26 monitors the temperature of the winding of the electric motor and the controller 15 is configured to turn off the electric motor 1 1 in case of failure.
- the controller 15 has a servo control for a servomotor as the electric motor 1 1. It is also conceivable that the controller 15 has a frequency control for a three-phase motor as an electric motor 1 1.
- the controller 15 may also include a motor control and / or startup control for the electric motor 1 1, which is preferably designed as a three-phase motor.
- the space requirement in the cabinet 2 can be reduced by eliminating circuits with contactors and wiring.
- the values of the sensors can all be forwarded via the bus line 16 to the machine control 3.
