In this embodiment, if the fully open door position detecting element 21 can detect that the bracket is located at the fully open door position 01 during the opening process of the kiln door 30, this indicates that the kiln door 30 is fully opened, and the detection of the fully open kiln door 30 is achieved. If the door 30 is not detected to be fully opened, a problem is illustrated.

Or the fully open door position detecting element 21 may be a distance sensor or a displacement sensor, where the distance sensor or the displacement sensor is disposed on the frame, and the sensing element is disposed at a certain position on the supporting element 122 or the chain 125, where when the supporting element 122 is located in the fully open door position 01, the sensing element is located at a certain distance from the distance sensor, the distance sensor can detect that the sensing element is located at a corresponding position, and the sensing element is located at a certain displacement from the displacement sensor or other reference points, and the displacement sensor can detect the displacement of the supporting element.
The above is only a few examples of the detecting element 21 for the fully opened door, and any detecting element that can change the signal when the supporting member 122 is located at other positions and the supporting member 122 is located at the fully opened door position 01 can be used, for example, the output signal of the detecting element changes from the presence to the absence, from the absence to the presence, or the value of the output signal changes.
As shown in fig. 1-4, further to the above embodiment, the kiln door status detection assembly 20 includes a unhooking position detection element 22, the unhooking position detection element 22 being configured to detect the arrival of the pallet at the unhooking position 02.
In this embodiment, the unhooking position detecting element 22 can detect whether the retraction of the supporting member is successful, if so, the next operation can be performed, and if not, the problem is described as existing, and the problem needs to be solved in time.
The unhooking position detecting element 22 may be a photoelectric switch, and a light blocking member or a light emitting member (such as a bulb) is disposed on the supporting member 122, when the supporting member 122 is located at the unhooking position 02, the light blocking member or the light emitting member can be opposite to the photoelectric switch, and when the supporting member 122 is located at other non-positions and at the unhooking position 02, output signals of the photoelectric switch are different.
Or the unhooking position detecting element 22 is a travel switch or a proximity switch, which is arranged at a position of the frame corresponding to the unhooking position 02 of the supporting member 122, and the supporting member 122 is provided with a triggering member, and when the supporting member 122 is positioned at the unhooking position 02, the triggering member triggers the travel switch or the position switch.
Alternatively, the unhooking position detecting element 22 may be a distance sensor or a displacement sensor, where the distance sensor or the displacement sensor is disposed on the frame, and the sensing element is disposed at a position on the supporting element 122 or the chain 125, where when the supporting element 122 is located at the unhooking position 02, the sensing element is located at a distance from the distance sensor, the distance sensor can detect that the sensing element is located at a corresponding position, and the sensing element is located at a displacement from the displacement sensor or other reference point, and the displacement sensor can detect the displacement of the supporting element.
The above is only a few examples of the unhooking position detecting element 22, and any detecting element that can change the signal between the rest 122 being located at other positions and the rest 122 being located at the unhooking position 02 may be used, for example, the output signal of the detecting element changes from the presence to the absence, from the absence to the presence, or the value of the output signal changes.
It should be noted that the full door opening position detecting element 21 and the unhooking position detecting element 22 may use the same type of sensor, and the sensor is marked to distinguish between the position of the supporting member 122 in the full door opening position and the position of the supporting member in the unhooking position. The full door opening position detecting element 21 and the unhooking position detecting element 22 employ different types of sensors to distinguish between the position of the tray 122 in the full door opening position and the position of the tray in the unhooking position according to different signals output.
Further, as shown in fig. 1, the bracket mechanism 10 includes a lifting frame 11, a driving assembly 12 is fixed on 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 kiln door status detection assembly 20 further comprises a door closing detection element 23, the door closing detection element 23 being fixed to the lifting frame 11.
In this embodiment, when the kiln doors 30 of a certain row and a certain column are opened, the lifting frame 11 is located at the bottom of the kiln door 30 before the bracket mechanism 10 is lifted to the corresponding kiln door 30 by the device, and is opposite to the current kiln door 30. The supporter in the driving assembly fixed to the lifting frame is hooked with the door opening member, and then the supporter 122 is upwardly operated 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, so that the kiln door 30 is closed 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 in the closing process of the kiln door 30 is described, 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 can be a position sensor, a distance sensor, a travel switch or a photoelectric switch, etc.
Further, the kiln door state detecting assembly further comprises a component for detecting the working state of the chain wheel shaft, so as to detect whether the kiln door 30 is unhooked or jammed.
For example: the kiln door status detection assembly 20 includes a pressure sensor 24 disposed on a sprocket shaft 128 (e.g., a driven sprocket shaft), the pressure sensor 24 being configured to detect a pressure of the sprocket shaft 128.
In the door opening process, after the supporting member 122 is hooked with the door opening member 50, the driving motor 15 drives the chain 125 to drive the supporting member 122 to move upwards, so that the kiln door 30 supports the kiln door 30, the kiln door 30 applies pressure to the supporting member 122, the chain wheel shaft 128 is applied with pressure, and after the supporting member 122 is unhooked with the door opening member 50, the pressure of the chain wheel shaft 128 disappears or becomes small. And when the kiln gate 30 experiences a stuck delay, the pressure sensor 24 becomes more pressurized than the set point.
During the closing process, the kiln door 30 automatically slides down under gravity until fully closed, and the support 122 slides down under the drive of the drive chain until retracted. When the kiln door 30 is jammed, the supporting member 122 moves downward to disengage from the door opening member 50, and 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 travel distance of the supporting member 122, the supporting member 122 abuts against the door closing member 40 before the supporting member 122 retracts, so that the pressure given by the door closing member 40 is received, and the pressure of the pressure sensor 24 suddenly increases or even exceeds the set pressure value, that is, when the pressure value of the pressure sensor 24 suddenly decreases and then suddenly increases during the door closing process, the jam of the kiln door 30 is indicated.
Therefore, the pressure change condition of the pressure sensor 24 can be used for detecting whether the kiln door 30 is unhooked or jammed, so that the problem can be found in time, and the use is convenient.
Moreover, the pressure sensor 24 is combined with the full door opening position detecting element 21, so that misjudgment of the full door opening position detecting element 21, for example, in the door opening process, the supporting member is unhooked from the door opening member 50, and the supporting member normally reaches the full door opening position and gives a signal, so that misjudgment of the kiln door 30 opening is performed. If the output signal of the pressure sensor 24 changes and the signal of the fully opened door position detecting element 21 changes, the unhooking phenomenon is avoided in the door opening process, and the kiln door 30 is opened in place.
The status of kiln door 30 during the door opening process is detected as follows:
(1) Kiln door 30 is normally opened: the full door opening position detecting element 21 has a signal, while the pressure sensor 24 has an output.
(2) Unhooking: the output of the pressure sensor 24 becomes drastically smaller.
(3) Kiln gate 30 is severely stuck: the pressure sensor 24 is greater than the set point.
If the kiln door 30 is normally opened, the next action can be executed; if the alarm is abnormal, the machine is stopped and the alarm is given.
The pressure sensor 24, the door closing detecting element 23 and the unhooking position detecting element 22 in combination detect the state of the kiln door 30 during the door closing as follows:
(1) Kiln door 30 is normally closed: the door closing detecting element 23 has a signal and the unhooking position detecting element 22 has a signal.
