[0021] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0022] like Figs. 1-6 The shown embodiment shows a fork mechanism for handling goods with fluid contents and packaging bags, including a suspension frame 1, wherein the suspension frame 1 includes a horizontal frame and a vertical frame, the vertical frame is fixedly connected to the right end of the horizontal frame, and a rectangular frame 2 is fixed inside the vertical frame, a fork mounting plate 3 is provided for rotation on the left side of the rectangular frame 2, and a connecting flange 3-1 is provided on the right end surface of the fork mounting plate 3, a slewing support plate 8 is installed on the slewing support plate 8, a slewing motor 9 is installed on the output shaft of the slewing motor 9, and a driving gear 10 is installed on the connecting flange 3-1, which is fixedly connected to a slewing gear 11 meshing with the driving gear 10 for transmission, and the fork mounting plate 3 is driven to rotate by the meshing transmission of the driving gear 10 and the slewing gear 11.

[0023] The left end face of the fork mounting plate 3 is fixed with the fixed guide rail support plates 12, and the fork plates 13 are slidably arranged between the guide rail support plates 12 through linear guide rails, and the main forks 4 are fixed on the fork plates 13.

[0024] An elevating motor seat 14 is fixed on the upper part of the left end face of the fork mounting plate 3, and the elevating motor 15 is installed in an inverted manner on the elevating motor seat 14, and a lifting bearing seat 16 is fixed on the middle part of the left end face of the fork mounting plate 3, and the elevating lead screw 17 is rotatably arranged between the elevating motor seat 14 and the lifting bearing seat 16, and the output shaft of the elevating motor 15 is in transmission connection with the elevating lead screw 17, and the elevating nut 18 in transmission cooperation with the elevating lead screw 17 is arranged on the fork plate 13. Through the transmission cooperation of the elevating lead screw 17 and the elevating nut 18, the up-and-down lifting of the main fork 4 is realized, so as to compact the upper end face of the packaging bag of the inner loaded goods.

[0025] The front and rear sides of the fork mounting plate 3 are respectively provided with the auxiliary forks 5 which can be moved inward to compact the side faces of the goods or moved outward to loosen the clamping of the goods, and the inner side surfaces of the auxiliary forks 5 are covered with iron sheets, so as to prevent the damage to the outer surfaces of the packaging bags when the auxiliary forks 5 clamp and compact the packaging bags during the carrying process.

[0026] Specifically, the structure for realizing the inward or outward movement of the auxiliary forks 5 is as follows: the upper end and the lower end of the right end face of the fork mounting plate 3 are respectively rotatably provided with the trapezoidal lead screws 24 which are in opposite rotation directions, and the front and rear ends of the trapezoidal lead screws 24 are respectively provided with the trapezoidal nuts 25 in mesh transmission cooperation with the trapezoidal lead screws 24, and the upper and lower trapezoidal nuts 25 located at the front end of the trapezoidal lead screw 24 are correspondingly fixedly connected with the upper and lower ends of the auxiliary forks 5 on the front side of the fork mounting plate 3, and the upper and lower trapezoidal nuts 25 located at the rear end of the trapezoidal lead screw 24 are correspondingly fixedly connected with the upper and lower ends of the auxiliary forks 5 on the rear side of the fork mounting plate 3.

[0027] The reduction motor 26 is installed on the upper part of the right end face of the fork mounting plate 3, the output shaft of the reduction motor 26 is in transmission connection with the upper trapezoidal lead screw 24 through the chain transmission 27, and then the shaft end of the upper trapezoidal lead screw 24 is in transmission connection with the lower trapezoidal lead screw 24 through the chain transmission 27, so that under the driving of the reduction motor 26, the upper and lower trapezoidal lead screws 24 are driven to rotate through the power transmission of the chain transmission 27, and the auxiliary forks 5 on the front and rear sides of the fork mounting plate 3 are driven to move inward or outward through the trapezoidal nuts 25.

[0028] When the auxiliary forks 5 move inward to clamp the packaging bags, the protruding parts on the side faces of the packaging bags are compacted to form a shape close to a plane, and then the main forks 4 act, so that the periphery of the packaging bags is compacted into a square shape, so that the packaging bags can be directly stacked without manually inserting the protruding parts on the periphery of the packaging bags inward, and the stacking of the packaging bags is ensured to be neat.

[0029] The bottom of the fork mounting plate 3 is fixed with a fork bottom plate 6 for stacking goods. After the goods on the fork bottom plate 6 are clamped by the main fork 4 and the auxiliary fork 5 and stacked on the ground or the goods stack, in order to smoothly pull out the main fork 4 and the auxiliary fork 5 from above and both sides of the goods, the lower part of the main fork 4 is provided with a push plate 7 for pushing the goods on the fork bottom plate 6 out.

[0030] The push plate 7 is extended or retracted through a set of scissor fork assemblies 19. The scissor fork assemblies 19 are respectively arranged on the front and rear sides of the right end face of the push plate 7, and a connecting rod 20 is arranged between the two scissor fork assemblies 19. The left end of the scissor fork assembly 19 is movably connected with the right end face of the push plate 7, and the right end of the scissor fork assembly 19 is movably connected with the connecting rod 20. The two ends of the connecting rod 20 are slidably connected with the fork mounting plate 3 through linear guides.

[0031] The lower part of the left end face of the fork mounting plate 3 is fixed with a pushing motor seat 21, and the pushing motor seat 21 is installed with a pushing motor 22. The pushing motor seat 21 and the lifting bearing seat 16 are rotatably connected with a pushing lead screw 23, and the connecting rod 20 is installed with a pushing nut in transmission cooperation with the pushing lead screw 23. When the pushing motor seat 21 drives the connecting rod 20 to descend along the linear guide through the pushing lead screw 23, the scissor fork assemblies 19 are opened with the descending of the connecting rod 20, so that the push plate 7 is pushed out until it abuts against the right side face of the packaging bag, and the packaging bag containing goods is pushed out from the fork bottom plate 6 and stacked. When the connecting rod 20 rises along the linear guide, the scissor fork assemblies 19 are retracted to reset the scissor fork assemblies 19.

[0032] When the goods are stacked, the packaging bag containing the goods is conveyed to the fork bottom plate 6, the rotating motor 9 drives the fork mounting plate 3 to rotate 90°, so that the main fork 4 is located at the side, and the two auxiliary forks 5 are respectively located at the upper and lower positions of the packaging bag. The speed reducer 26 drives the trapezoidal screw 24 to rotate, and drives the two auxiliary forks 5 to move towards the packaging bag to compress the protruding parts on both sides of the packaging bag. At the same time, the lifting motor 15 drives the lifting screw 17 to rotate, and the lifting screw 17 is in transmission cooperation with the lifting nut 18, so as to drive the main fork 4 to descend and press the upper end surface of the packaging bag containing the goods. Then the rotating motor 9 drives the fork mounting plate 3 to continue to rotate 90°, so that the main fork 4 is located below the packaging bag. At this time, the packaging bag is in a clamped state by the main fork 4 and the auxiliary fork 5. After the carrying fork mechanism clamps the packaging bag and stacks it on the ground or the goods pile, the main fork 4 rises to release the clamping of the packaging bag. The pushing motor base 21 drives the connecting rod 20 to descend along the linear guide rail through the pushing screw 23, and the scissor fork assembly 19 extends with the descending of the connecting rod 20, so as to push the pushing plate 7 to abut against the side of the packaging bag. The carrying fork mechanism moves away from the packaging bag. Since the pushing plate 7 pushes the packaging bag, the auxiliary fork 5 gradually withdraws from both sides of the packaging bag, and moves away from the packaging bag together with the main fork 4. The packaging bag is pushed out of the fork bottom plate 6 by the pushing plate 7 and is stacked. When the connecting rod 20 rises along the linear guide rail, the scissor fork assembly 19 retracts to reset the scissor fork assembly 19.

[0033] The carrying fork mechanism with the above structure clamps and presses the packaging bag containing the goods on both sides through the auxiliary fork 5. Thus, when the packaging bag is carried and stacked, it is not necessary to specially arrange personnel to tightly press the protruding parts on both sides of the packaging bag inward, so that the automation of the goods carrying operation is realized, which is beneficial to reduce the operation cost and improve the operation efficiency.

[0034] Based on the above ideal embodiments according to the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the contents in the specification, and must be determined according to the scope of claims.
