TECHNICAL FIELD

[0001] The present application relates to the technical field of transportation devices, in particular to a full-flexibility device and method for automatically adapting to position deviation. BACKGROUND

[0002] When delivering goods into a vehicle compartment, the delivery device needs to enter the vehicle compartment after the vehicle is parked to deliver the goods. Generally, the length of the delivery device is similar to the width of the vehicle compartment opening, so that the delivery of the goods into the vehicle compartment can complete the pre-set stacking of the goods with the total length. In the process of delivering the stacked goods, the delivery device first completes the layer-by-layer stacking of the goods in the area close to the vehicle head of the vehicle compartment, and then retracts by a distance of one goods for the stacking of the next stack of goods. When the vehicle compartment is gradually stacked, the delivery device gradually withdraws from the vehicle compartment.

[0003] However, in actual situations, when the delivery device moves into the vehicle compartment, the vehicle compartment and the delivery device are misaligned or have an angle, which can cause the delivery device to fail to accurately move into the vehicle compartment. The delivery device with a width similar to the width of the vehicle compartment opening is difficult to accurately extend into the vehicle compartment, and the delivery device that is easy to extend into the vehicle compartment is difficult to deliver goods with the pre-set total length at one time, which requires multiple deliveries of the goods in the same layer and results in low efficiency of delivering the goods.

DETAILED DESCRIPTION

[0019] The following will be combined Figures 1-3 to further illustrate the present application.

[0020] Referring to Figure 1 and Figure 2 , the device for automatically adapting to position deviation in full flexibility comprises a rack 1, the rack 1 is provided with a guide rail 3, the guide rail 3 is provided with a mobile working platform, the mobile working platform has a fixed section 2 and two telescopic sections 4, which are respectively arranged at both ends of the length direction of the fixed section 2, and the two telescopic sections 4 can synchronously extend and retract in the length direction of the fixed section 2. The telescopic section 4 is an extension of the working area of the fixed section 2, so that the mobile working platform can extend and retract, and after the telescopic section 4 extends from the fixed section 2, the mobile working platform and the telescopic section 4 together transport the goods.

[0021] The length of the fixed section 2 is less than the width of the opening of the carriage, and the fixed section 2 can extend into the carriage even if there is some deviation in the parking position of the truck.

[0022] After the mobile working platform enters the carriage, the fixed section 2 cannot send the single-row goods into the carriage in batches, and the position of the fixed section 2 in the carriage is difficult to control, so it is difficult to deliver the goods to the accurate position. The two telescopic sections 4 are synchronously extended in the carriage, the telescopic section 4 closer to the inner wall of the carriage first abuts against the inner wall of the carriage, pushes the fixed section 2 to slide on the guide rail 3 to the other side, until the extension length of the other telescopic section 4 reaches the preset total length, and the whole row of goods can be stacked in the carriage while leaving enough movement gap.

[0023] With reference to Figure 1 and Figure 2 , the fixed section 2 has a driving assembly, the driving assembly includes push rods 5, chain wheels 8 and a chain 9, the fixed section 2 is fixed with a mounting plate 7, the mounting plate 7 is fixed with a driving motor 6, the chain wheel 8 has two, one is coaxially fixed on the output shaft of the driving motor 6, and the other is fixed on the mounting plate 7, and the chain 9 connects the two chain wheels 8. One end of the push rod 5 is on the chain 9, and the other end is on the telescopic section 4, and the two push rods 5 are in different directions of the chain 9, that is, the orientations of the two push rods 5 are opposite. The driving motor 6 drives the chain wheel 8 to rotate, so as to drive the push rod 5 to move, and the rotation direction of the chain wheel 8 can be controlled, that is, the synchronous extension and retraction of the telescopic section 4 can be controlled.

[0024] It can be understood that the chain wheel 8 and the chain 9 in the embodiment are only one of the implementation manners of the driving assembly, and in some other embodiments, the driving assembly can also be two opposite orientation air cylinders, electric push rods and the like, as long as the synchronous extension and retraction of the two telescopic sections 4 can be realized.

[0025] With reference to Figure 1 and Figure 2 , when the mobile working platform enters the carriage, the driving motor 6 is operated to make the push rod 5 push the telescopic section 4 to extend, and since the two telescopic sections 4 extend synchronously, when the telescopic section 4 on one side abuts against the inner wall of the carriage, the power of the further extension of the telescopic section 4 pushes the fixed section 2 to slide on the guide rail 3, so that the fixed section 2 slides to the other side until the total length after the extension of the two telescopic sections 4 meets the preset total length.

[0026] With reference to Figure 1 and Figure 2 , the inner wall of the fixed section 2 is provided with a roller 11, and the side wall of the telescopic section 4 is provided with a sliding groove 10 for the roller 11 to roll. The roller 11 supports the telescopic section 4, and at the same time, through cooperation with the sliding groove 10, the extension direction of the telescopic section 4 is guided during the extension and retraction of the telescopic section 4.

[0027] With reference to Figure 1 and Figure 2, the edge of the fixed section 2 is provided with an anti-collision wheel 20 which protrudes from the side wall of the fixed section 2. After each stack of goods is completed, the moving work platform is moved out of the vehicle compartment by a distance of one row of goods, and the stacking of the next stack of goods is carried out. Due to the unevenness of the inner wall of the vehicle compartment, the telescopic section 4 may be stuck in the recess when it abuts against the inner wall of the vehicle compartment. Through the arrangement of the anti-collision wheel 20, when the telescopic section 4 moves on the inner wall of the vehicle compartment, the anti-collision wheel 20 rolls on the inner wall of the vehicle compartment, so that the telescopic section 4 can roll on the inner wall of the vehicle compartment to avoid being stuck in the recess.

[0028] Referring to Figure 1 and Figure 2 , after the stacking of the goods in the vehicle compartment is completed, the moving work platform needs to be reset for subsequent use, so a reset assembly is arranged in the rack 1. The reset assembly includes two reset springs 12 and a baffle 13. The two reset springs 12 are arranged in a line and fixed on the side wall of the rack 1, and the baffle 13 is fixed between the two reset springs 12. Meanwhile, the top end of the baffle 13 is also fixedly connected with the fixed section 2. In the initial state, the moving work platform is centered on the rack 1, the baffle 13 is between the two reset springs 12, and neither of the two reset springs 12 is under stress. When the fixed section 2 is moved under the push of the telescopic section 4, the baffle 13 is moved under the drive of the fixed section 2, one reset spring 12 is compressed, and the other reset spring 12 is stretched.

[0029] Under the elastic force of the reset spring 12, the moving work platform continuously pushes against the inner wall of one side of the vehicle compartment, and when the moving work platform gradually comes out of the vehicle compartment, the anti-collision wheel 20 will come out of the vehicle compartment first. At this time, the moving work platform will be side-shifted under the action of the reset spring 12, causing the goods at the door of the vehicle compartment to be difficult to stack. Therefore, a brake assembly is arranged in the rack 1 to lock the moving work platform on the guide rail 3, so as to ensure the stacking of the goods at the door of the vehicle compartment.

[0030] Referring to Figure 1 and Figure 3 Figure 1 Figure 3 , the brake assembly includes an electromagnet 18, a swing lever 17 and a friction plate 16. The swing lever 17 is hinged to the rack 1, and the electromagnet 18 is fixed to the rack 1. The bottom end of the swing lever 17 is provided with a magnetic block 19 which can be attracted or repelled by the electromagnet 18. The friction plate 16 is arranged at the end of the swing lever 17 away from the electromagnet 18, and the friction plate 16 is fixed to the side of the swing lever 17 facing the fixed section 2. In the normal state, the magnetic pole of the electromagnet 18 is the same as that of the magnetic block 19, so that the friction plate 16 abuts against the side wall of the fixed section 2, and the moving work platform is locked on the guide rail 3. After the truck is parked stably, the moving work platform enters the vehicle compartment, the electromagnet 18 is energized, so that the magnetic pole of the electromagnet 18 is the same as that of the magnetic block 19. Under the lever action of the swing lever 17, the friction plate 16 is separated from the side wall of the fixed section 2, and the moving work platform can freely slide on the guide rail 3.

[0031] It is easy to understand that the brake assembly is not limited to the form of the electromagnet 19 and the swing rod 17, and in some other embodiments, it can also be a structure such as a hydraulic cylinder, which can apply a pushing force and a pulling force to the friction plate 16, so that the friction plate 16 abuts or separates from the fixed section 2.

[0032] The implementation process of the embodiment of the present application is as follows: in the initial state, the telescopic sections 4 are all retracted into the fixed section 2, and the magnetic poles of the electromagnet 18 are the same as the magnetic block 19. After the driver stops the truck, the mobile working platform is extended into the truck compartment. Since the width of the fixed section 2 is smaller than the width of the truck compartment, and it is not necessary to ensure that the mobile working platform is centered in the truck compartment, the mobile working platform can quickly and accurately enter the truck compartment. The electromagnet 18 is energized and attracted to the magnetic block 19, so that the mobile working platform can freely slide on the guide rail 3. The driving motor 6 operates to synchronously extend the two telescopic sections 4 until the total length of the mobile working platform meets the preset total length requirement. Then the goods are transported. When the mobile working platform approaches the truck door, the electromagnet 18 is de-energized and repelled from the magnetic block 19, so that the fixed section 2 is locked on the guide rail 3. After the goods are transported and the truck drives away, the telescopic sections 4 are retracted, the electromagnet 18 is energized and attracted to the magnetic block 19, and the mobile working platform is reset under the action of the reset spring 12.

[0033] The present application also discloses a full-flexible automatic position deviation adapting method, which is used in cooperation with the full-flexible automatic position deviation adapting device and comprises the following steps. S1, after the truck is stopped, the mobile working platform enters the truck compartment, and the telescopic sections 4 are retracted into the fixed section 2. The electromagnet 18 is energized, so that the magnetic poles are changed from the same to the opposite, the friction plate 16 is separated from the fixed section 2, and the mobile working platform can freely slide on the guide rail 3.

[0034] S2, the driving motor 6 operates, the telescopic sections 4 are synchronously extended under the action of the push rod 5, the telescopic section 4 first contacting the inner wall of the truck compartment pushes the fixed section 2 to slide on the guide rail 3, until the total length of the mobile working platform meets the preset total length requirement, the preset total length approaches the width of the truck compartment, the extension of the telescopic section 4 is stopped, and the mobile working platform is basically centered in the truck compartment.

[0035] S3, the goods are stacked, and the mobile working platform is retreated by a distance of a row of goods after each stack of goods is completed.

[0036] S4, when the mobile working platform approaches the truck door, the electromagnet 18 of the brake assembly is de-energized and repelled from the magnetic block 19, so that the friction plate 16 locks the mobile working platform on the guide rail 3. When the mobile working platform approaches the truck door, the current row of goods is stacked, the mobile working platform is partially moved out of the truck compartment when the next row of goods is stacked.

[0037] S5, continue to stack the goods until the whole truck is stacked, and the truck drives away. The driving motor 6 operates to retract the telescopic section 4 into the fixed section 2.

[0038] S6, the electromagnet 18 is powered and attracted to the magnetic block 19, the friction plate 16 is separated from the moving working platform, the moving working platform is reset under the action of the reset spring 12 and is centered on the frame. Then, the electromagnet 18 is powered off and repelled from the magnetic block 19, so that the friction plate 16 locks the moving working platform on the guide rail 3, which is used for stacking other goods of the truck.

[0039] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
