Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

Referring to fig. 1, the present embodiment provides a material flow conveying system, which includes a conveying line 100, wherein the conveying line 100 preferably, but not limited to, is in a closed loop structure to circularly convey a plurality of material boxes (not shown in fig. 1), so that each material box receives externally provided material at a receiving station of the conveying line 100, and discharges the material at a discharging station of the conveying line 100.

Specifically, a docking mechanism 200 is provided at each of the unloading stations of the conveyor line 100, the docking mechanism 200 can be docked with the conveyor line 100 at an upstream portion thereof and the conveyor line 100 at a downstream portion thereof so as to continuously convey the magazines, and the docking mechanism 200 can be flipped at an appropriate angle around one side of the extending direction of the conveyor line 100 so as to flip the magazines thereon at a corresponding angle so as to pour the materials in the magazines, or to facilitate manual removal of the materials in the magazines at one side of the unloading station. The conveyor line 100 and the docking mechanism 200 may be a roller/belt conveyor mechanism or the like in the prior art, which is not described herein.

In order to make the docking mechanism 200 perform the above-mentioned turning action, the logistics conveying system further includes a discharging device 300 disposed at each discharging station of the conveying line 100, please refer to fig. 2, wherein the discharging device 300 includes a frame 1, a turning plate 2 and a pushing mechanism 3, the turning plate 2 is disposed below the discharging station and is used for fixing and carrying the docking structure. Flap 2 is pivoted to frame 1, the pivots of which are located substantially below the lateral edges of conveyor line 100 and parallel to the extension of conveyor line 100. The pushing mechanism 3 is configured to bear and push the turning plate 2 upwards, so that the turning plate 2 can be turned upwards out of the bearing surface of the conveying line 100 (the bearing surface when the docking mechanism 200 is docked with the conveying line 100), that is, the docking mechanism 200 and the magazine on the docking mechanism 200 are turned over respectively.

Referring to fig. 2, the pushing mechanism 3 includes a driving portion 31 fixed on the frame 1 and a pushing rod 32 connected between the driving portion 31 and the turning plate 2. It should be noted that, in this embodiment, a relatively movable overlapping structure is formed between the push rod 32 and the flap 2, that is, a part of the total weight of the flap 2 and its load (the magazine 400 and the material) is supported by the hinge of the frame 1, and another part is supported by the overlapping part of the end of the push rod 32.

As shown in fig. 4, when the driving portion 31 is operated in the forward direction, the push rod 32 can be driven to move in the forward direction to push the plate 2 upwards to an inclined posture, so as to complete the unloading task of the material loading box 400 on the docking mechanism 200. When the driving portion 31 works in the reverse direction, the push rod 32 can be driven to move in the reverse direction to reset the turning plate 2 to the horizontal posture for butting the butting mechanism 200 with the conveying line 100, as shown in fig. 3. When the turning plate 2 is pushed up to the extreme overturning position of the inclined posture, an acute angle is formed between the turning plate and the bearing surface of the conveying line 100, so that when the pushing mechanism 3 is reset, the turning plate 2 can be reset under the self-weight.

The driving portion 31 is electrically connected to a controller (not shown), based on the detection signals of the material detecting elements such as the photoelectric switch and the pressure sensor disposed on the docking mechanism 200, the controller can stop the docking mechanism 200 and issue the operation command of the forward motion to the driving portion 31, based on the estimated and set holding time suitable for the material cartridge 400 to be completely inclined or for the material in the material cartridge 400 to be manually taken out, after the controller issues the operation command at the timing and counts the sum of the time required by the driving portion 31 to complete the operation command and the holding time, the controller can automatically issue the reset command for the driving portion 31 to reversely move, so as to reset the docking mechanism 200, and output the material cartridge 400 to the downstream conveying line 100 for receiving the next material cartridge 400 transmitted from the upstream conveying line 100.

Although the push rod 32 and the flap 2 are in an overlapping structure, in the resetting process of the push rod 32 and the flap 2, the push rod 32 cannot forcibly pull the flap 2 to move downwards synchronously with the pull rod 32, but the moving speed of the push rod 32 is limited to be less than the moving speed of the flap 2 reset under the action of gravity when the driving part 31 works reversely, so that the flap 2 can be kept pressed against the push plate, namely, a gap G cannot occur between the flap 2 and the part of the push rod 32 for bearing the flap 2.

However, during the resetting process, if the flap 2 is actively supported by a human, the flap 2 with the slower resetting speed will generate a relative displacement with the push rod 32 due to the speed difference, that is, the flap 2 will be separated from the portion of the push rod 32 for bearing the same and form a gap G, as shown in fig. 5. If the gap G can be monitored and a stop signal is sent to the driving part 31 of the pushing mechanism 3 when the gap G is generated, the push rod 32 can be stopped in time so as to support the turning plate 2 and prevent the turning plate 2 from being reset.

Therefore, in this embodiment, the discharging device 300 further includes a first detecting element 4 electrically connected to the controller, the first detecting element 4 is configured to detect the distance between the turning plate 2 and the pushing mechanism 3, after receiving the detection signal of the first detecting element 4, the first detecting element 4 can be triggered to generate a trigger signal, and the controller can issue the stop signal to the driving portion 31 in time based on the trigger signal of the first detecting element 4.

When the driving part 31 executes the reverse action of resetting after receiving the resetting instruction automatically issued by the controller, if the material in the material box 400 is not completely inclined or is not taken out manually, the manual operation can drag the resetting of the slow turning plate 2 or stop the resetting of the turning plate 2 through supporting/pulling the parts such as the striker plate on the turning plate 2, and the like, so that the first detection element 4 can generate the trigger signal to stop the driving part 31, and the material which is not poured out or taken out in the material box 400 can be taken out manually.

Meanwhile, if the material accidentally falling onto the conveying line 100 is clamped into the gap formed between the docking mechanism 200 and the conveying line 100, and the turning plate 2 is clamped, the first detection element 4 can generate the trigger signal, so that the manual timely processing is facilitated, meanwhile, due to the overlapping structure of the turning plate 2 and the push rod 32 in the embodiment, the turning plate 2 cannot be forcibly pulled by the push rod 32 to extrude commodities, and the stagnation of the conveying line 100 caused by the fact that the docking mechanism 200 and the conveying line 100 are clamped by the material can also be avoided.

Specifically, the discharging method of the discharging device 300 can be referred to as follows, which includes:

s1, conveying the material box 400 to be unloaded to an unloading station by the conveying line 100;

s2, issuing an operation instruction to the pushing mechanism 3, and pushing the turning plate 2 upwards by the pushing mechanism 3 to enable the turning plate 2 to be turned upwards to turn over the material box 400 to a discharging state;

s3, issuing a reset instruction to the pushing mechanism 3, resetting the pushing mechanism 3 and enabling the turnover plate 2 to reset along with the resetting; during the resetting of the flap 2, the drive mechanism 3 is deactivated if the first detection element 4 is triggered.

Further, in order to facilitate the controller to judge whether the braking requirement at the moment is based on the triggering of the manual active supporting of the turning plate 2 or the interference jamming of the turning plate 2 by the material on the conveying line 100 for further processing, the discharging method further comprises the following steps:

s31, after the pushing mechanism 3 is stopped, if the trigger state of the first detecting element 4 disappears, the reset command is issued to the pushing mechanism 3 again after the preset delay time.

That is, it can be determined that the braking demand at this time is caused by manually and actively supporting the flap 2, after the flap 2 is manually released, the flap 2 can be continuously reset and overlapped with the push rod 32, so that the trigger state of the first detection element 4 disappears, at this time, the controller can issue a reset instruction to the pushing mechanism 3 again after a preset delay time, which is a time for manually providing the time for continuously taking out the material which is not poured/taken out from the magazine 400, and which may be slightly shorter than the above-mentioned holding time.

S32, after the pushing mechanism 3 is stopped, if the first detecting element 4 is continuously in the trigger state, an operation command is issued to the pushing mechanism 3.

That is, the braking demand at this moment is that turning over board 2 is blockked and arouses, and the controller can be after the trigger signal that continuously receives first detecting element 4 to another preset delay time, assign the operation instruction to pushing mechanism 3 to the clamping state of turning over board 2 is relieved, and the material of conveyer belt department is taken out in the manual work of being convenient for, also can avoid the material to be turned over board 2 long term extrusion and damage.

Furthermore, in order to minimize unnecessary delay, the discharging method further comprises:

s311, if the first detecting element 4 is triggered again within the preset delay time, a reset command is issued to the pushing mechanism 3.

That is, after the material that is not poured/taken out from the material box 400 is manually taken out continuously, the turning plate 2 is pulled again to trigger the first detecting element 4, and the controller can immediately issue an operation instruction to the pushing mechanism 3 without waiting for the controller to time to reach the preset delay time.

The controller and the material detecting element may be implemented by the prior art, and are not described herein.

Next, please continue to refer to fig. 3, fig. 4 and fig. 5 to describe the discharging device 300 in detail.

In this embodiment, the turning plate 2 may include a plate body 21 and a slide block 22, and the plate body 21 is disposed below the unloading station and pivotally connected to the frame 1. The bottom side of the plate body 21 is provided with a sliding groove (not shown), the sliding groove is arranged along a direction perpendicular to the extending direction of the conveying line 100, the sliding block 22 is connected in the sliding groove in a sliding manner, the sliding block 22 is provided with a strip hole 221 extending along the pushing direction of the pushing mechanism 3, the top end of the push rod 32 is provided with a plug pin 321 inserted into the strip hole 221, and the plug pin 321 supports the sliding block 22 at the top end of the strip hole 221, so that the push rod 32 and the turning plate 2 form a lap joint structure.

The first detecting element 4 is preferably, but not limited to, a proximity switch, which is fixedly connected to the slider 22 and is brought into contact with the proximity switch when the distance between the latch 321 and the top end of the bar hole 221 is greater than the preset distance, so that the proximity switch is triggered. Optionally, the detection end of the proximity switch is disposed at the bottom end of the bar hole 221.

In fig. 3, the flap 2 is in a substantially horizontal reset state, and the docking mechanism 200 mounted thereon is docked with the conveyor line 100, and at this time, the latch 321 holds the slider 22 at the top end of the bar hole 221, and the first detection element 4 is not triggered. In fig. 4, the driving portion 31 drives the push rod 32 to rotate clockwise in the view, so that the flip plate 2 is switched from the tilted operating state to the reset state, the pin 321 still continuously supports the slider 22 on the top end of the slot 221, and the first detecting element 4 is not triggered. In fig. 5, the driving portion 31 drives the push rod 32 to rotate clockwise in the drawing, so that the turning plate 2 is switched from the inclined operation state to the reset state, in the process, if the turning plate 2 is actively supported manually or the turning plate 2 is clamped by the material on the conveying line 100, the plate body 21 cannot continue to rotate, and the push rod 32 continues to rotate under the driving of the driving portion 31 until the push rod abuts against the first detecting element 4, so as to trigger the first detecting element 4.

As shown in fig. 6, in order to avoid that the latch 321 accidentally triggers the first detecting element 4 when the flap 2 is switched from the unloading state to the resetting state because the instantaneous speed of the push rod 32 is much greater than the falling speed of the plate body 21 with zero initial speed of falling only by self weight, in this embodiment, the first elastic member 5 is preferably disposed on the slider 22, and the first elastic member 5 can apply upward pushing force to the latch 321. The first elastic member 5 may be an elastic sheet fixed to the slider 22. Preferably, a second elastic member 6 may be further disposed between the frame 1 and the plate 21, and the second elastic member 6 can apply a downward pulling force to the plate 21, so that the plate 21 is continuously pressed against the plug 321, so as to further ensure that the plug 321 does not accidentally trigger the first detecting element 4. It can be understood that the sum of the upward pushing force applied by the first elastic member 5 to the latch 321 and the downward pulling force applied by the second elastic member 6 to the plate body 21 is less than the driving force of the driving portion 31 to drive the push rod 32.

In addition, the discharging device 300 further comprises a second detection element 7 electrically connected with the pushing mechanism 3, when the turning plate 2 is reset, the second detection element 7 can be triggered, so that the controller can confirm that the turning plate 2 is reset based on a detection signal of the second detection element 7.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, adaptations and substitutions will occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments.
