Definitions
- the invention relates to a sewing machine with a machine housing, that on a table top from an operating position to a maintenance position is pivotally mounted, with a mounted in the machine housing Main shaft, with one with the main shaft in rotary drive connection Drive motor and with an electric; with a drive motor related safety device that provides a power supply the drive motor pivoted in the maintenance position Has machine housing interrupting switch.
- the sewing machine To make the sewing machine accessible for maintenance, it can be removed from the operating position are pivoted to the maintenance position. Especially For sewing machines with direct drive it must be ensured that an (unintentional) commissioning is excluded if the machine housing is in the service position to injury of the personnel handling the machine. This is on the base plate of the machine housing located below the table a switch mounted in the operating position of the sewing machine with a plate located on the tabletop engages and then closed is. The switch is electric with the control of the sewing machine connected, so that in the operating position a sewing operation possible is. If the machine housing is pivoted into the maintenance position, opens the switch, thereby interrupting any power supply to the drive motor so that an operation in this position is excluded.
- the invention is the task underlying to improve the initially described sewing machine to that the functional safety of the two positions of the machine housing monitoring safety device is improved and simultaneously the design effort for the assembly and manufacture of the safety device is reduced.
- the switch is formed by gravity operable and directly on a with a control for the drive motor related board is arranged.
- the switch is operated by gravity, the inclination of the machine housing is reliably detected, so that from a predetermined inclination of the machine housing, the power supply to the drive motor is safely interrupted and unintentional operation of the counter is excluded by the staff.
- the switch directly on a board so a printed circuit attached is, an existing anyway in the machine housing board can be used
- electromagnetic to be controlled pneumatic valves one the Stichstelle illuminating lighting device and signalers via a bus connected to the electrical control. This is eliminated any work on or in the machine housing a separate line for the safety device.
- the switch designed as a reed switch, the inductive by means of a permanent magnet is actuated, which is arranged displaceably guided in a housing.
- the housing receiving the reed switch from two housing halves, which are glued together.
- a cost-effective, prefabricated component can be produced, which can be easily integrated into the sewing machine.
- the Gluing the housing halves ensures that contamination the components included therein is excluded, so that over a long service life, the functional reliability is guaranteed.
- the switching of the reed switch by means of the permanent magnet is advantageously carried out in that the permanent magnet in an elongated Recess of the housing is arranged, the two opposite to each other arranged floors, one of which the reed switch adjacent Floor in operating position lower than that of the reed switch distant ground and where the reed switch adjacent ground in the service position is higher than the removed floor, so that the Permanent magnet when tilting the machine housing reliably in the recess changes its position relative to the reed switch.
- the safety device can preferably also on the drive motor be arranged.
- the sewing machine has a machine housing that consists of an arm 1 and a fixedly connected to the arm 1 base plate 2 is formed and the drive means, such as a drive motor 3 and a main shaft forming arm shaft 4, which via a toothed belt 5 is connected to the drive motor 3, receives.
- the machine housing 1, 2 is pivotally mounted on a table top 7 via a hinge 6.
- Fig. 2 shows the sewing machine in solid form in an upright Operating position A and in dash-dot representation in maintenance position B.
- a circuit board 8 is arranged in the arm 1, the over a line 9 is electrically connected to a controller 10, which in turn is electrically connected via a line 11 to the drive motor 3.
- a safety device 12 is attached, which is also electrically connected to the drive motor 3 communicates.
- the safety device 12 has one of two together bondable housing halves 13, 14 existing housing.
- the housing takes in provided in the housing halves 13, 14 recesses 18, 19 a reed switch 20.
- the reed switch 20 acts with a cylindrical permanent magnet 15 together, in one in the housing 13, 14 is guided by recesses 16, 17 formed cavity.
- This Cavity 16, 17 is arranged obliquely.
- In the erected operating position A of the sewing machine is the reed switch 20 adjacent Floor 16a, 17a of the cavity 16, 17 deeper than that of the reed switch 20th removed bottom 16b, 17b.
- Fig. 3 shows the safety device 12 in the operating position A of Sewing machine.
- the permanent magnet 15 is located at the bottom 16 a, 17 a in the Top view elongate cavity 16, 17 and pulls a not closer shown contact tongue of the reed switch 20, so that the reed switch 20 is closed and the control device 10, the drive motor 3 is powered.
- the housing halves 13, 14 are semicircular lugs 21, 22nd provided in the case-sealed housing halves 13, 14 circular Form feet over which the housing 13, 14 attached to the board 8 so that the assembly of the safety device is easy is possible.
- the safety device 12 can of course also directly on the each Drive motor 3 associated motor board 24 may be arranged. These is usually also with the controller 12 via a line 25 in Connection and interrupts in the manner described the power supply to the drive motor 3 when the machine housing 1, 2 in the maintenance position B is pivoted. This naturally only applies if the Drive motor 3 is located in or on the machine housing 1, 2 and with this pivoted from the operating position A in the maintenance position B. becomes.
