[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] As attached Figure 1As shown, a cargo transfer system and transfer method for two storage rooms include a first transport device 2 and a second transport device 3, wherein the first transport device 2 and the second transport device 3 are both conveyor belt transport devices, each including a conveyor belt, a conveyor belt support and a conveyor belt driving device, and the first transport device 2 and the second transport device 3 are respectively installed in the adjacent first storage room 5 and the second storage room 6; in a first embodiment, the transport surfaces of the first transport device 2 and the second transport device 3 are on the same horizontal plane, and the transport extension lines of the first transport device 2 and the second transport device 3 are on the same straight line; the first storage room 5 and the second storage room 6 are provided with a partition wall 36, and the partition wall 36 is provided with a transport passage 7, and the transport passage 7 connects the first storage room 5 and the second storage room The storage room 6 is connected; it also includes a temporary isolation plate 4, which can make the transportation channel 7 closed or open. The temporary isolation plate 4 can make the transportation channel 7 closed or open by lifting, rotating, sliding and other movements. In this scheme, the temporary isolation plate 4 uses a lifting movement to make the transportation channel 7 closed or open; when the transportation channel 7 is in a closed state, the temporary isolation plate 4 and the transportation channel 7 are sealed, and the internal space of the second storage room 6 is a closed space; the first transportation device 2 and the second transportation device 3 are provided with a transfer device 1, and the transfer device 1 is located in the first storage room 5. When the transportation channel 7 is in an open state, the transfer device 1 can horizontally transfer the goods on the first transportation device 3 to the second transportation device 3.

[0036] like Figure 3As shown, the transfer device 1 includes a translation device 8 and a third transport device 9, and the third transport device 9 is a conveyor belt transport device, including a conveyor belt, a conveyor belt bracket and a conveyor belt driving device; the translation device 8 is fixedly installed on the first transport device 2 and the second transport device 3, and the third transport device 9 is slidably installed on the translation device 8. In the first embodiment, the transport surface of the third transport device 9 is on the same horizontal plane as the transport surface of the first transport device 2 and the second transport device 3, and the length of the third transport device 9 is less than the distance between the ends of the first transport device 2 and the second transport device 3 that are close to each other. The translation device 8 can drive the third transport device 9 to move between the first transport device 2 and the second transport device 3. The second transport device 3 slides, so that the third transport device 9 docks with the first transport device 2 or the second transport device 3. When the translation device 8 drives the third transport device 9 to move to the extreme position close to one end of the first transport device 2, the end of the third transport device 9 close to the first transport device 2 docks with the first transport device 2, and the goods on the first transport device 2 can be transferred to the third transport device 9; when the translation device 8 drives the third transport device 9 to move to the extreme position close to one end of the second transport device 3, the end of the third transport device 9 close to the second transport device 3 docks with the second transport device 3, and the goods on the third transport device 9 can be transferred to the second transport device 3.

[0037] like Figure 5 and 6 As shown, the translation device 8 includes a support frame 12 and a translation drive device 13. The support frame 12 is fixedly installed on the ground, and the translation drive device 13 is installed in the support frame 12. A guide channel 26 is opened at the upper end of the support frame 12 along the length direction of the third transport device 9. In the first embodiment, the guide channel 26 is horizontally arranged, and the lower end of the third transport device 9 is slidably fitted in the guide channel 26. When the third transport device 9 is slidably installed on the support frame 12, the translation drive device 13 is driven and connected to the third transport device 9. The translation drive device 13 can drive the third transport device 9 to slide relative to the support frame 12. The sliding cooperation between the lower end of the device 9 and the guide channel 26 can guide the sliding of the third transport device 9 relative to the support frame 12, and can ensure that the third transport device 9 always slides at the same level relative to the support frame 12, thereby ensuring that when the third transport device 9 is driven by the translation drive device 13 to move to the position where it docks with the first transport device 2, the transport surface of the third movement device 9 is on the same horizontal plane as the transport surface of the first transport device 2; at the same time, it can also ensure that when the third transport device 9 is driven by the translation drive device 13 to move to the position where it docks with the second transport device 3, the transport surface of the third movement device 9 is on the same horizontal plane as the transport surface of the second transport device 3.

[0038] like Figure 5 As shown, the translation drive device 13 includes a sprocket drive motor 17, a driving sprocket 18, a driving chain 19, a drag chain 20 and a driven sprocket 21, the sprocket drive motor 17 is installed on the support frame 12, the driving sprocket 18 is coaxially installed on the driving shaft of the sprocket drive motor 17, the driven sprocket 21 is installed on the side of the mounting platform 27 away from the sprocket drive motor 17 through a sprocket bracket, and the axis of the driven sprocket 21 and the axis of the driving sprocket 18 are in the same horizontal plane, the driving chain 19 is simultaneously surrounded by the driving sprocket 18 and the driven sprocket 21, and the two ends of the driving chain 19 are connected to the lower end of the third transport device 9; in the assembled state, the line connecting the axis of the driven sprocket 21 and the axis of the driving sprocket 18 is a horizontal line along the length direction of the third transport device 9, the The drive chain 19 forms two parallel horizontal chain segments, and each of the horizontal chain segments is parallel to the line connecting the axis of the driven sprocket 21 and the axis of the driving sprocket 18, and the two ends of the drive chain 19 are located on any horizontal chain segment; when the drive chain 19 is driven by the driving sprocket 18 to reciprocate, the drive chain 19 can drive the third transport device 9 to slide relative to the support 12; since the two ends of the drive chain 19 are connected to the lower end of the third transport device 9, and the two ends of the drive chain 19 are located on any horizontal chain segment, in the process of the driving sprocket 18 driving the drive chain 19 to reciprocate, the two ends of the drive chain 19 do not contact the driving sprocket 18 and the driven sprocket 21, thereby ensuring that the drive chain 19 drives the third transport device 9 to slide horizontally reciprocatingly relative to the translation device 8.

[0039] like Figure 4 As shown, a transport drive box 29 is provided at the center of one end of the third transport device 9 away from the transport surface, and the transport drive box 29 can drive the third transport device 9 to perform transport action. A synchronous plate 11 is fixedly connected to the side of the transport drive box 29 away from the third transport device 9, and both ends of the third transport device 9 away from the transport surface are provided with sliding wheels 10 relative to the guide channel 26; in the assembled state, both ends of the drive chain 19 are connected to the synchronous plate 11, and each of the sliding wheels 10 is slidably matched in the guide channel 26; when the drive chain 19 moves under the drive of the active sprocket 18, the third transport device 9 moves synchronously with the drive chain 19 driven by the synchronous plate 11, and slides back and forth horizontally relative to the support frame 12, and the sliding cooperation between the sliding wheel 10 and the guide channel 26 guides the horizontal reciprocating sliding of the third transport device 9 relative to the support frame 12.

[0040] like Figure 5As shown, the support frame 12 is also provided with a first photoelectric switch 24 and a second photoelectric switch 23, and the first photoelectric switch 24 and the second photoelectric switch 23 are both located below the synchronization plate 11, and the first photoelectric switch 24 and the second photoelectric switch 23 are both electrically connected to the sprocket drive motor 17. When the third transport device 9 slides horizontally relative to the support frame 12, when the synchronization plate 11 moves to the top of the first photoelectric switch 24 driven by the drive chain 19, the photoelectric signal of the first photoelectric switch 24 is blocked by the synchronization plate 11, and the first photoelectric switch 24 controls the sprocket drive. The motor 17 stops running, so that the third transport device 9 stops at the position docking with the first transport device 2, so that the goods on the first transport device 2 can be transferred to the third transport device 9; when the synchronization plate 11 moves to the top of the second photoelectric switch 23 driven by the drive chain 19, the photoelectric signal of the second photoelectric switch 23 is blocked by the synchronization plate 11, and the second photoelectric switch 23 controls the sprocket drive motor 17 to stop running, so that the third transport device 9 stops at the position docking with the second transport device 3, so that the goods on the third transport device 9 can be transferred to the second transport device 3.

[0041] like Figure 5As shown, the support frame 12 is also provided with a first emergency stop switch 25 and a second emergency stop switch 22, and the first emergency stop switch 25 and the second emergency stop switch 22 are respectively located on the side away from the first photoelectric switch 24 and the second photoelectric switch 23, and the reset buttons of the first emergency stop switch 25 and the second emergency stop switch 22 are both higher than the plane where the synchronization plate 11 is located; in the process where the third transport device 9 moves toward the direction close to the first transport device 2 through the synchronization plate 11 driven by the drive chain 19, if the synchronization plate 11 moves to the top of the first photoelectric switch 24, and the sprocket drive motor 17 does not stop running due to a fault of the first photoelectric switch 24, the end of the synchronization plate 11 close to the first emergency stop switch 25 is pressed on the reset button of the first emergency stop switch 25, and the first emergency stop switch 25 urgently cuts off the power supply of the sprocket drive motor 17, so that the third transport device 9 cannot continue to slide relative to the support frame 12, thereby avoiding the third transport device 9 from colliding with the first transport device 2; when the third transport device 9 moves toward the second transport device 3 through the synchronization plate 11 driven by the drive chain 19, if the synchronization plate 11 moves above the second photoelectric switch 23, and the sprocket drive motor 17 does not stop running due to a malfunction of the second photoelectric switch 23, the end of the synchronization plate 11 close to the second emergency stop switch 22 is pressed on the reset button of the second emergency stop switch 22, and the second emergency stop switch 22 urgently cuts off the power supply of the sprocket drive motor 17, so that the third transport device 9 cannot continue to slide relative to the support frame 12, thereby avoiding the third transport device 9 from colliding with the second transport device 3.

[0042] In the initial state, the temporary isolation plate 4 keeps the transport passage 7 in a closed state, and the third transport device 9 is not docked with the first transport device 2 .

[0043] In a first embodiment of the present invention, a method for transferring goods between two storage spaces is provided:

[0044] Step 1: The temporary isolation board 4 is slid vertically upward relative to the transport passage 7 by means of the lifting switch, thereby separating the temporary isolation board 4 from the transport passage 7, so that the transport passage 7 is in an open and closed state;

[0045] Step 2: Start the sprocket drive motor 17 to make the driving sprocket 18 rotate in the positive direction, so that the third transport device 9 slides relative to the support seat 12 in a direction close to the first transport device 2 under the drive of the translation drive device 13;

[0046] When the synchronization plate 11 moves to the top of the first photoelectric switch 24, the first photoelectric switch 24 controls the sprocket drive motor 17 to stop running, so that the third transport device 9 is located at a position for docking with the first transport device 2;

[0047] Step 3: In the state of step 2, the conveyor belts of the first conveying device 2 and the third conveying device 9 are controlled to drive at the same time, so that the goods on the first conveying device 2 are transferred to the third conveying device 9;

[0048] Step 4: In the state of step 3, the third transport device 9 is paused from continuing to transmit and the sprocket drive motor 17 is restarted to make the driving sprocket 18 rotate in the opposite direction, so that the third transport device 9 is driven by the translation drive device 13 to slide relative to the support seat 12 in a direction close to the second transport device 3;

[0049] When the synchronization plate 11 moves to the upper side of the second photoelectric switch 23, the second photoelectric switch 23 controls the sprocket drive motor 17 to stop running, so that the third transport device 9 is located at a position for docking with the second transport device 3;

[0050] Step 5: Under the condition of step 4, the conveyor belts of the second transport device 3 and the third transport device 9 are controlled to transmit simultaneously, so that the goods on the third transport device 9 are transferred to the second transport device 3 .

[0051] Step six: When the transport channel 7 needs to be closed, start the sprocket drive motor 17 to make the active sprocket 18 rotate forward, and the third transport device 9, driven by the translation drive device 13, slides relative to the support seat 12 toward the first transport device 2; thereby causing the end of the third transport device 9 close to the transport channel 7 to leave the range of the transport channel 7.

[0052] The above content is the first embodiment of the present invention. However, in actual applications, since the first transport device 2 and the second transport device 3 do not have only a shorter transport range as shown in the figure, but have a longer transport route, due to unavoidable factors such as the error between the flatness of the bottom surface and the system error of the first transport device 2 and the third transport device 3, the transport surface of the first transport device 2 and the transport surface of the second transport device 3 may not necessarily be on the same horizontal plane. Therefore, in the actual transportation process, there is a small height difference between the transport surface of the first transport device 2 and the transport surface of the second transport device 3. In order to solve the above problem, the present invention proposes a second embodiment.

[0053] In order to solve the problem of how to transfer goods between the first transport device 2 and the second transport device 3 with a small height difference through the transfer device 1, when designing the transfer device 1, the translation device 8 should be set at an angle, and when the third transport device 9 is slidably installed on the translation device 8, the third transport device 9 is parallel to the translation device 8 and is also set at an angle to the ground, so that the transport surface of the third transport device 9 is close to the end of the first transport device 2 and is flush with the transport surface of the first transport device 2, and the transport surface of the third transport device 9 is close to the end of the second transport device 3 and is flush with the transport surface of the second transport device 3.

[0054] The support frame 12 includes two side columns 15 arranged in parallel along the transport direction of the third transport device 9, and the upper ends of the side columns 15 are provided with a cross beam 14 supporting the third transport device 9 along the length direction. The guide channel 26 is opened on the cross beam 14, and the sliding wheels 10 on both sides of the third transport device 9 are rollingly fitted in their respective corresponding guide channels 26; a driving platform 27 is provided between the two side columns 12 along the length direction of the side columns 15, and the translation drive device 13 is installed on the installation platform 27, and adjustable feet 16 are provided on the lower sides of the two ends of the side columns 15 in the extension direction, and the vertical distance between any end of the side column 15 along the length direction and the ground can be adjusted through the adjustable feet 16. As a result, the side columns 15 on the support frame 12 are set at an angle to the ground, and the crossbeam 14 installed at the upper end of the side column 15, the guide channel 26 opened on the crossbeam 14, the third transport device 9 slidably installed on the guide channel 26, the driving platform 27 installed between the two side columns 12, the connecting line between the axis of the active sprocket 18 installed on the support frame 12 and the axis of the driven sprocket 21 and the transmission direction of the drive chain 19 are all parallel to the third and side columns 15, and are also set at an angle with the ground, and the angle is the same; and at this time, the transport surface of the third transport device 9 is close to the first transport device 2 and is flush with the transport surface of the first transport device 2, and the transport surface of the third transport device 9 is close to the second transport device 3 and is flush with the transport surface of the second transport device 3; since the height difference between the transport surface of the first transport device 2 and the transport surface of the second transport device 3 is small, the inclined third transport device 9 will not hinder the transfer of goods on the first transport device 2 to the transport surface of the third transport device 9.

[0055] Similarly, while keeping the connecting line between the axis of the driving sprocket 18 and the axis of the driven sprocket 21 and the transmission direction of the drive chain 19 horizontal, and by setting height compensation and length compensation devices at the connection between the drive chain 19 and the synchronous plate 11, the goods on the first transport device 2 can be transferred to the third transport device 2 via the inclined third transport device 9.

[0056] However, no matter in the first embodiment or in the second embodiment, the temporary isolation board 4 is controlled by a separate lifting switch to move up and down relative to the transport passage 7. Therefore, when a fire or other malfunction occurs in the first storage room 5 or the second storage room 6, a staff member is required to press the lifting switch separately so that the temporary isolation board 4 closes the transport passage 7. However, the time required for the temporary isolation board 4 to slide vertically downward relative to the transport passage 7 is relatively long. Therefore, the storage room on fire cannot be isolated in time, which may easily cause the fire source to spill over. Therefore, the third embodiment is proposed in the present invention.

[0057] like Figure 7 As shown, in the third embodiment of the present invention, it also includes a synchronous pulley group, which includes a movable pulley 28, a first fixed pulley 31, a second fixed pulley 32, a third fixed pulley 33 and a steel cable 35. The two movable pulleys 28 are respectively installed on both sides of the third transport device 9 through a movable pulley bracket 29, and are arranged at a distance relative to the support frame 12. The two first fixed pulleys 31 are installed on both sides of the support frame 12 close to one end of the first transport device 2 through a fixed pulley bracket 30, and are arranged in the same plane as the movable pulley 28. The two second fixed pulleys 32 are installed in parallel on the top plate of the first storage room 5, and a sliding rail is provided on the isolation wall 36 corresponding to the temporary isolation board 4 The two third fixed pulleys 33 are installed in parallel at the top of the sliding track and are located above the transport channel 7; the support frame 12 is also fixed with two sections of steel cables 35 corresponding to the two movable pulleys 28 at one end close to the first transport device 2, and the other end of each steel cable 35 passes through the corresponding movable pulley 28, the first fixed pulley 31, the second fixed pulley 32 and the third fixed pulley 33 in turn and is finally connected to the two ends of the top of the temporary isolation board 4 respectively; when the third transport device 9 slides relative to the support frame 12, the temporary isolation board 4 slides vertically relative to the transport channel 7 synchronously with the third transport device 9 through the synchronous pulley set and the steel cable 35.

[0058] When the translation device 8 drives the third transport device 9 to move horizontally in the direction close to the second transport device 3, the third transport device 9 has a horizontal pulling force on the steel cable 35, and the pulling force is greater than the gravity of the temporary isolation board 7 itself; the distance between the movable pulley 28 and the first fixed pulley 31 will increase, thereby causing the length of the steel cable 35 wrapped around the movable pulley 28 and the first fixed pulley 31 to increase. Since the total length of the steel cable 35 is fixed, the increase in the length of the steel cable 35 between the movable pulley 28 and the first fixed pulley 31 will cause the length of the steel cable 35 between the third fixed pulley 33 and the upper end of the temporary isolation board 7 to become shorter, thereby causing the temporary isolation board 4 to slide vertically upward relative to the transport channel 7 under the pull of the steel cable 35. When the third transport device 9 moves horizontally relative to the translation device 8 to the position where it docks with the second transport device 3, the transport channel 7 is in a connected state, and the goods on the third transport device 9 can be transferred to the second transport device 3 without hindrance;

[0059] When the translation device 8 drives the third transport device 9 to move horizontally in the direction close to the first transport device 2, the third transport device 9 has a horizontal pulling force on the steel cable 35, and the pulling force is equal to the gravity of the temporary isolation board 7 itself; the distance between the movable pulley 28 and the first fixed pulley 31 will become shorter, thereby causing the length of the steel cable 35 wrapped around the movable pulley 28 and the first fixed pulley 31 to become shorter. Since the total length of the steel cable 35 is fixed, the shortening of the length of the steel cable 35 between the movable pulley 28 and the first fixed pulley 31 will cause the length of the steel cable 35 between the third fixed pulley 33 and the upper end of the temporary isolation board 7 to become longer, thereby causing the temporary isolation board 4 to slide vertically downward relative to the transport channel 7 under the action of its own gravity. When the third transport device 9 moves horizontally relative to the translation device 8 to a position docking with the first transport device 2, the transport channel 7 is in a closed state. At this time, when an accident occurs in the second storage room 6, harmful substances will not overflow outside the second storage room 6.

[0060] A force sensor is provided at the connection between the steel cable 35 and the temporary isolation board 4, and the force sensor can detect the magnitude of the force acting on the connection between the steel cable 35 and the temporary isolation board 4. When the third transport device 9 moves horizontally relative to the translation device 8 to the position docking with the second transport device 3 and transfers goods with the second transport device 3, if the force sensor detects that the pulling force of the steel cable 35 on the temporary isolation board 4 is less than the gravity of the temporary isolation board 4 itself, the temporary isolation board 4 will slide vertically downward relative to the transport channel 7 under the action of its own gravity. At this time, the third transport device 9 slides relative to the translation device 8 in the direction close to the first transport device 2 under the joint action of the synchronous pulley set and the steel cable 35. At the same time, the force sensor transmits the detected abnormal data to the control system, and the control system After receiving the signal, the translation drive device 13 is controlled to drive the third transport device 9 to move toward the direction close to the first transport device 2, so as to prevent the temporary isolation board 4 from causing damage to the third transport device 9 and the cargo during the process of sliding vertically downward relative to the transport channel 7 under the action of its own gravity; a buffer device 34 is provided at the bottom end of the transport channel 7, and the buffer device 34 can be a spring buffer, a liquid buffer, a gas buffer or other buffer structure. When the temporary isolation board 4 slides vertically downward relative to the transport channel 7 under the action of its own gravity and contacts the buffer device 34, the buffer device 34 can buffer the impact force of the temporary isolation board 4, so as to prevent the temporary isolation board 4 from being deformed due to excessive impact force during descent, causing the temporary isolation board 4 to be stuck in the transport channel 7.

[0061] In a third embodiment of the present invention, a method for transferring goods between two storage spaces is provided:

[0062] Step 1: Start the sprocket drive motor 17 to make the driving sprocket 18 rotate forward, so that the third transport device 9 slides relative to the support seat 12 toward the first transport device 2 under the drive of the translation drive device 13. During this process, the temporary isolation plate 4 slides vertically downward relative to the transport channel 7 under the drive of the synchronous pulley block and the steel cable 35;

[0063] Step 2: When the synchronization plate 11 moves to the top of the first photoelectric switch 24, the first photoelectric switch 24 controls the sprocket drive motor 17 to stop running, so that the third transport device 9 is located at a position to dock with the first transport device 2. At this time, the transport channel 7 is in a completely closed state under the action of the temporary isolation plate 4;

[0064] Step 3: In the state of step 2, the conveyor belts of the first conveying device 2 and the third conveying device 9 are controlled to drive at the same time, so that the goods on the first conveying device 2 are transferred to the third conveying device 9;

[0065] Step 4: In the state of step 3, the third transport device 9 is paused from continuing to transmit and the sprocket drive motor 17 is restarted to make the driving sprocket 18 rotate in the opposite direction, so that the third transport device 9 is driven by the translation drive device 13 to slide relative to the support seat 12 in the direction close to the second transport device 3. In this process, the temporary isolation plate 4 is driven by the synchronous pulley block and the steel cable 35 to slide vertically upward relative to the transport channel 7;

[0066] Step 5: In the state of step 4, when the synchronization plate 11 moves to the top of the second photoelectric switch 23, the second photoelectric switch 23 controls the sprocket drive motor 17 to stop running, so that the third transport device 9 is located at a position for docking with the second transport device 3. At this time, the temporary isolation plate 4 slides to the top of the transport channel 7, so that the transport channel 7 is in a fully open state;

[0067] Step six: Under the condition of step five, the conveyor belts of the second transport device 3 and the third transport device 9 are controlled to transmit simultaneously, so that the goods on the third transport device 9 are transferred to the second transport device 3 .

[0068] Step 7: Repeating steps 1 to 6 continuously can continuously transfer goods between the first storage room 5 and the second storage room 6.

[0069] The above are preferred embodiments of the present invention. It should be pointed out that a person skilled in the art may make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the protection scope of the present invention.
