Second, the pre-action set may be performed on the plug assembly 40. First, the number of the protection blankets 50 is fixed when the protection blankets 50 are stacked. When the sliding table 33 reaches the first position, the telescopic arm 41 configured as a servo electric push rod in the plugging assembly 40 is set in advance, and the control unit configured as a PLC control system controls the distance of each extension of the telescopic arm 41, so that each time the plugging member 43 of the plugging assembly 40 is inserted into the gap of the uppermost protective blanket 50, then the control unit configured as the PLC control system records the time required by each action of the telescopic arm 41, and the time is set to X1, X2, X3, … … Xn, wherein n is the number of layers of the protective blanket 50 to be moved.

The pre-action setting is then performed on conveyor 20, the time required for each blanket 50 to pass through the two first rollers 231 is recorded in advance, and the size setting of each blanket 50 is the same, so t1 can be taken as the time period between each blanket 50 passing through the two first rollers 231. The telescopic rod 212b configured as a servo hydraulic cylinder is set so as to descend each time to a distance slightly greater than the thickness of each of the protection blankets 50, and the guide table 300 provided on the elevating table 212a just guides the movement of the protection blanket 50 on the uppermost layer, and the time of each descent of the telescopic rod 212b configured as a hydraulic cylinder is recorded as t2.

In addition, a reset sensor (shown in the drawing) for detecting the presence or absence of the protection blanket 50 may be provided on the placement board 70, and the reset sensor may be configured as a photoelectric sensor, and the reset sensor is in communication connection with a control unit configured as a PLC control system, and when detecting that the placement area 13 does not have the protection blanket 50, the reset sensor configured as the photoelectric sensor is fed back to the PLC control system, and the PLC control system controls the first driving assembly 30, the plugging assembly 40, and the conveying mechanism 20 to be reset.

Furthermore, it should be understood that in other possible embodiments, the control unit may also be configured as a controller, without limitation.

The present disclosure exemplarily describes an operation of the paving apparatus. Firstly, the protective door 90 is opened, the placing plate 70 is placed in the placing area 13, then a plurality of protective blankets 50 are neatly stacked on the placing plate 70, then the protective door 90 is closed, a control unit configured as a PLC control system (not shown in the figure) controls the first motor, the first motor is operated so that two first rollers 231 rotate around the own axis, the control unit controls a second driving motor 31 configured as a servo motor in a first driving mechanism to operate, the sliding table 33 is enabled to move along a screw rod 32 in a first direction, after the sliding table 33 reaches a first position, the first servo motor feeds back a signal to the control unit, the control unit controls a telescopic arm 41 configured as a servo electric push rod in a plug-in assembly 40 to extend, the plug-in connector 43 is plugged in a gap of the protective blanket 50, after the control unit controls the sliding table 33 of the first driving mechanism to stop moving, a waiting time Xn (n is the number of layers of the protective blanket 50 to be moved), when the sliding table moves to the second position, the sliding table 33 is moved to the second position, the sliding table is controlled by the control unit to move by the preset sliding table 20 b, and after the telescopic arm 24 is retracted to the first position, the telescopic arm is retracted by the preset cylinder 2b, the first control unit is retracted by the control unit, and a cycle is completed after the sliding table is moved to the first position, the telescopic arm is retracted by the preset cylinder control unit is controlled by the control unit, and the telescopic arm is retracted by the control unit, and the telescopic rod is retracted by the telescopic rod is retracted. Until the reset sensor detects that protective blanket 50 is not present on placement board 70, the control unit controls the reset of the mechanisms. Wherein, when each mechanism puts in the protection blanket 50, the staff can push the car body 10 to move so that each protection blanket 50 is laid on the bottom surface.

It should be appreciated that other modes of operation of conveyor 20, first drive assembly 30, and plug assembly 40 in a burst blanket laying apparatus are possible. For example, in other possible embodiments, a control panel (not shown) with control buttons may be provided, through which a worker may send instructions to a control unit that controls conveyor 20, first drive assembly 30, and plug assembly 40 in the blast blanket placement device according to the instructions to complete the placement of blanket 50.

The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, but the present disclosure is not limited to the specific details of the embodiments described above, and various simple modifications may be made to the technical solutions of the present disclosure within the scope of the technical concept of the present disclosure, and all the simple modifications belong to the protection scope of the present disclosure.

In addition, the specific features described in the foregoing embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, the present disclosure does not further describe various possible combinations.

Moreover, any combination between the various embodiments of the present disclosure is possible as long as it does not depart from the spirit of the present disclosure, which should also be construed as the disclosure of the present disclosure.
