The above are only a few examples of the unhooking position detecting element 22, and any detecting element that can realize the signal change between the position where the tray 122 is located at another position and the unhooking position 02 of the tray 122 can be adopted, for example, the output signal of the detecting element is changed from the existence or nonexistence, or from the nonexistence or the value of the output signal is changed.
It should be noted that the same type of sensor can be used for the fully-opened door position detecting element 21 and the unhooking position detecting element 22, and the sensor is marked to distinguish the tray 122 in the fully-opened door position from the tray in the unhooking position. The fully-opened position detecting element 21 and the unhooking position detecting element 22 use different types of sensors, and distinguish between the fully-opened position of the tray 122 and the unhooking position of the tray by outputting different signals.
As shown in fig. 1, on the basis of the above embodiment, further, the carriage mechanism 10 includes a lifting frame 11, the driving assembly 12 is fixed to the lifting frame 11, and the driving assembly 12 is disposed downstream of the frame 121 in the opening direction of the kiln door 30; the door status detecting assembly 20 further includes a door closing detecting element 23, and the door closing detecting element 23 is fixed on the lifting frame 11.
In this embodiment, when the kiln doors 30 in a certain row and a certain column are opened, the bracket mechanism 10 is lifted to the front of the corresponding kiln door 30 by the device, and the lifting frame 11 is located at the bottom of the kiln door 30 and opposite to the kiln door 30. The holder in the driving assembly fixed to the elevating frame is hooked with the door opening unit, and then the holder 122 is moved upward by the driving motor 15 to open the kiln door 30.
The door closing detection element 23 is arranged on the lifting frame 11, when the kiln door 30 is opened and the kiln door 30 is closed, the output signals of the door closing detection element are different, the closing detection of the kiln door 30 is realized according to the change of the output signal of the door closing detection element 23, and when the output signal of the door closing detection element changes in the door closing process, the kiln door 30 is completely closed. If the signal is unchanged, the problem occurs in the closing process of the kiln door 30, and the problem needs to be solved, so that the kiln door 30 is ensured to be closed in time.
The door closing detection element may be a position sensor, a distance sensor, a travel switch, or a photoelectric switch, among others.
On the basis of the above embodiment, further, the kiln door state detection assembly further includes a component for detecting the working state of the sprocket shaft, so as to detect whether the kiln door 30 is unhooked or stuck.
For example: the door state detecting assembly 20 includes a pressure sensor 24 provided on a sprocket shaft 128 (e.g., a driven sprocket shaft), and the pressure sensor 24 is configured to detect a pressure of the sprocket shaft 128.
In the door opening process, after the support member 122 is hooked with the door opening member 50, the driving motor 15 drives the chain 125 to drive the support member 122 to move upwards, so that the kiln door 30 is supported, the kiln door 30 applies pressure to the support member 122, the chain wheel shaft 128 is pressed, and after the support member 122 is unhooked from the door opening member 50, the pressure of the chain wheel shaft 128 disappears or becomes small. When the door 30 is stuck, the pressure of the pressure sensor 24 becomes higher than the set value.
In the door closing process, under normal conditions, the kiln door 30 automatically slides downwards under the gravity until being completely closed, and the support piece 122 slides downwards under the driving of the transmission chain until retracting. When the kiln door 30 is stuck, the support member 122 moves downwards first to be separated from the door opening member 50, at this time, the pressure of the pressure sensor 24 becomes smaller, and because the distance between the door closing member 40 and the door opening member 50 is smaller than the stroke distance of the support member 122, before the support member 122 retracts, the support member 122 abuts against the door closing member 40, so that the pressure given by the door closing member 40 is received, the pressure of the pressure sensor 24 suddenly becomes larger and even exceeds a set pressure value, that is, in the door closing process, when the pressure value of the pressure sensor 24 suddenly becomes smaller and then becomes larger, the blockage of the kiln door 30 is indicated.
Therefore, whether the kiln door 30 is unhooked or blocked can be detected through the pressure change condition of the pressure sensor 24, so that problems can be found in time, and the kiln door is convenient to use.
Moreover, the pressure sensor 24 is combined with the fully-opened door position detecting element 21, so that the situation that the fully-opened door position detecting element 21 judges wrongly can be eliminated, for example, in the door opening process, the supporting piece is unhooked from the door opening piece 50, and the supporting piece normally reaches the fully-opened door position and gives a signal to judge that the kiln door 30 is opened in place wrongly. If the output signal of the pressure sensor 24 changes and the signal of the fully-opened position detecting element 21 changes, it indicates that the unhooking phenomenon does not occur in the door opening process, and the kiln door 30 is opened in place.
The state of the kiln door 30 during the door opening process is detected as follows:
(1) the kiln door 30 is normally opened: the fully open door position detecting element 21 has a signal and the pressure sensor 24 has an output.
(2) Unhooking: the pressure sensor 24 output sharply decreases.
(3) The kiln door 30 is severely stuck: the pressure sensor 24 is greater than the set value.
If the kiln door 30 is opened normally, the next action can be executed; if the abnormal condition exists, the machine is stopped to alarm.
The pressure sensor 24, the door closing detection element 23 and the unhooking position detection element 22 detect the state of the pair of doors 30 during the door closing process as follows:
(1) the kiln door 30 is normally closed: the door closing detection element 23 has a signal, and the unhooking position detection element 22 has a signal.
(2) The kiln door 30 is severely stuck: the unhooking position detection element 22 has no signal, and the output of the pressure sensor 24 rapidly decreases and then rapidly increases.
If the kiln door 30 is normally closed, the next action can be executed; if the abnormal condition exists, the machine is stopped to alarm.
For another example: as shown in fig. 7, the kiln door state detection assembly includes a connecting rod 25, a reset member 27, a limit member 26, and a connecting rod position detection element 28; one end of the connecting rod 25 is connected to the sprocket shaft 128 through the top plate of the frame, the stopper 26 is fixed to a portion of the connecting rod 25 located outside the frame, the restoring member 27 is connected between the stopper 26 and the frame, and the connecting rod position detecting element 28 is fixed to the top plate of the frame to detect the upper limit position of the connecting rod 25.
