Description

[Detailed Description of the Invention] 4 = The invention provides a system in which, for example, in a combine harvester, when a blockage occurs in a grain transfer path or a blockage occurs in a grain transfer device, an alarm such as a buzzer is activated. The present invention relates to an improvement in an alarm device that issues an alarm and lights up a lamp indicating the location of the trouble on a sign board provided near the driver's seat.

As mentioned above, an alarm that is activated when trouble occurs;
Alarm devices consisting of a sign board that indicates the location of trouble are equipped with a stop switch to stop the activated alarm, but in the case of conventional alarm devices, the stop switch for stopping the activated alarm is The number of switches installed on the operation panel is increased because the various switches are installed in parallel with the various switches on the operation panel surface, which is located away from the sign board (monitor panel) that indicates the location where the problem occurs. , there are problems with the operation of these switches that cause incorrect operation and complicate the mechanism and wiring.
Moreover, when you know that a trouble has occurred due to the activation of the alarm, and you have to leave the driver's seat to deal with the problem, it is a hassle to search for the stop switch to stop the alarm from operating. However, there have been problems such as erroneous operation or failure to determine where the trouble occurred while operating the stop switch.

The present invention has been made to solve these problems.It does not increase the number of switches provided on the operation panel, simplifies wiring, and allows you to easily grasp the location of trouble. The purpose is to propose a new means that can stop the operation of the Sho-178 device.

In order to achieve this object, an alarm device according to the present invention is an alarm device that includes an alarm that is activated when a trouble occurs and a sign board that indicates the location where the trouble has occurred by lighting. The present invention is characterized by a stop switch that stops the operation of the above-mentioned alarm when touched or pressed. The alarm device to be installed to correspond to this will be explained in detail according to the drawings.

FIG. 1 is a plan view of a combine harvester A in which the present invention can be carried out. (2) shows a monitor spring (sign plate) installed on the operation panel (1).

The monitor panel (2) serving as a sign board is formed into a box shape as shown in FIGS. 2 and 3. /C body (20)
On the panel (21) attached to the front of the
Locations where troubles occur, such as malfunctions in the bag feeder of the bag filling machine, are printed and separated by item. and,
On the back 1 (inside) of the panel (21), the parts corresponding to each of the above items are provided with the box-shaped bodies (20
) The lamp (22)... assembled in
As shown in the wiring diagram in Figure 4, these lamps (22) are each connected to a circuit that is closed by a detection switch (23) that is activated when a trouble is detected. It is the same as before that each sensor switch (23) lights up individually when activated, and the lighting indicates the occurrence of a trouble and its location.

(3) is an alarm device connected to the circuit described in QiJ and installed at an appropriate position on the aircraft so that it will operate and issue an alarm when any of the above-mentioned sensing switches (23)... are activated. (
(4) is a stop switch that stops the operation of the alarm (3). When the alarm (3) is activated by the activation of the sensing switch (23), the stop switch (4) is configured to:
In Fig. 4, the current is passed in the order of A → B → Bar > 2 and HO, and from there, the uf moving contact (5I) is excited by the coil (50) installed between C and 2. move it,
The circuit is switched to a state where the current flows in the order of A → B → C → II → G → J → S→, the circuit of the alarm (3) is opened, and the operation of the alarm (3) is stopped. The container (3) is
While the sensing switch (23) is operating, the movable contact piece 6υ is self-held at the switched position by the solenoid excited by the coil (50), so that the switch (23) is stopped.
h It is maintained in the L state.

Therefore, as shown in FIG. 3, the body stop switch (4) is connected to the body (20
) into the mounting part (1a) provided on the operation panel (1) so as to be able to slide up and down, and fix the bottom of the hotey (20) to the aircraft body on the underside of the operation panel (1). The support base (24) provided as
Attach the movable contact piece (40) to the bottom of 01, and move the body (
On the F side of 20), a pair of fixed contacts (41) (41) facing the movable contact piece (40) are arranged and attached to the above-mentioned support base (24), and the fixed contacts (41)・(41)
As shown in the wiring diagram in FIG. 4, by connecting the monitor panel (2) to the circuit that controls the operation of the alarm (3), the monitor panel (2) itself can be pressed to activate the alarm. (3) A stop switch is configured to stop the operation.

This stop switch (4) has a fixed contact (41
)・(41) includes the body (2) of the monitor panel (2).
A limit switch is provided below the bottom of the monitor panel (
When the body (20) of 2) is pushed in, the bottom of the body (20) pushes the operating rod of the limit switch to turn it "on", or the monitor panel (2)
) body (20) is fixed to the operation panel (1), and the panel (21) attached to the body (20) is movable, and by pushing this panel (2I), The aforementioned movable contact piece (40) is a fixed contact (41)
- (41) may be designed as appropriate, such as making contact with (41), and forming the above-mentioned point (21) into a touch switch that is activated by touching the fingertip,
The monitor panel (2) may be configured to be activated by touching the monitor panel (2) with a fingertip.

Next, to explain the function and effect, the alarm device according to the present invention configured as described above has a stop switch that stops the operation of the alarm activated by the occurrence of the trough JL.
Monitor panel to indicate the location of the problem (
Since it is configured to be activated by pushing in the display panel (sign board) or by touching the monitor panel, it is possible to know when a trouble has occurred by checking the activation of the device, and to check the trough where the problem occurred.
To disable the countermeasures, when leaving the driver's seat and deactivating the alarm that continues to issue the alarm, the child should directly touch the monitor panel (sign board) that indicates the location where the trough-JL has occurred. Since the operation of the tower alarm device will be stopped (cancelled), the location where the problem has occurred will be reliably determined. stops the alarm (
Since this is a stop switch that activates the alarm (release), the number of switches on the operation panel where switches are arranged side by side is reduced by the number of switches corresponding to this stop switch to reduce the number of malfunctions caused by various switch operations, and also to stop the alarm from operating. It makes operation easy and reliable, and also simplifies the wiring of the operation panel and switches installed on it.
