Description

Technical Field

[0001] The invention relates to the technical field of shelves, and in particular to a shelf frame body which is easy to load and unload goods. Background Art

[0002] Shelf frames refer to the basic structure of the storage system used to store goods or commodities in warehouses, supermarkets, factories and other places. The design, material selection, manufacturing process, etc. of the shelf frames will affect its load-bearing capacity, safety and service life. Shelf frames are divided into many types and can be selected according to different needs. When using shelf frames, it is generally necessary to load and unload goods. Shelves that are easy to load and unload goods are widely favored.

[0003] The existing patent CN111602978A discloses a three-dimensional shelf, comprising a bottom frame, a bottom wall of the bottom frame is welded with a plurality of supporting legs, and columns are welded at the four corners of the top wall of the bottom frame, the bottom end of the side wall of the column away from the middle of the bottom frame is connected to a mounting plate by screws, a buffer spring is fixedly installed on the side wall of the mounting plate away from the column, one end of the buffer spring is fixedly connected to a buffer railing, the top of the column is connected to the top frame by bolts, the four corners of the bottom wall of the top frame near the middle are connected to the inner column by bolts, a plurality of short arms are longitudinally arranged and welded on the side wall of the inner column close to the column, the top wall of the short arm is fixedly provided with a convex head, and the short arm is limited by the convex head and carries a short layer board.

[0019] The beneficial effects of the present invention are as follows:

[0020] When installing a cargo box, the present invention uses a palletizing robot to place the cargo box on the supporting assembly, and uses a rolling assembly to push the cargo box to a reasonable position of the supporting assembly until the cargo box contacts the contact assembly. Under the action of the transmission assembly, the rolling assembly is forced to rotate, so that the cargo box does not roll in the loading direction. When the cargo box contacts the supporting assembly, the supporting assembly moves downward under the action of the gravity of the cargo box, so that the cargo box is supported. At the same time, under the action of the inflation assembly, the clamping assembly is forced to move. When the cargo box completely moves to the end of the supporting assembly, the palletizing robot is used to completely release the cargo box, so that the clamping assembly clamps the side of the cargo box to prevent the cargo box from rolling. Under the action of the rolling component, free rolling occurs, at which time the rotating connecting component itself engages, and the installation of each layer of cargo boxes is completed in sequence; when unloading each layer of cargo boxes, the air pressure of the clamping component of the corresponding layer is released, and the cargo boxes of the corresponding layer are pulled outward by the stacking robot until the rotating connecting component is separated, the supporting component retreats, and the clamping component is forced to retreat, thereby releasing the cargo box, until the cargo box is separated from the contact component, so that the contact component drives the transmission component to rotate, and the rolling component rotates to a reasonable position, and then the cargo box of the corresponding layer is quickly pulled out by the stacking robot to achieve the purpose of fast unloading; when taking out the cargo boxes of any layer and the above cargo boxes at the same time, first release the clamping component of the corresponding layer. The air pressure in the holding component releases the cargo box in contact with the palletizing robot, and the palletizing robot supports the cargo box and lifts the corresponding cargo box to move the cargo box upward. At the same time, under the action of the rotating connection component, the sliding component moves outward, and the sliding component drives the supporting component of the upper layer to move. Under the action of the rolling component, the cargo box on the upper layer has rolling friction. Due to the balanced force on both sides, the cargo box does not move until the cargo box is separated from the supporting component. At this time, the cargo box on the corresponding layer just contacts the cargo box on the upper layer, completing the removal of the cargo box and the cargo box on the upper layer. By analogy, the cargo boxes on any layer and the above cargo boxes can be taken out at the same time, and any cargo boxes in the middle position can be removed at the same time. The invention relates to a shelf body which is easy to load and unload goods. When loading and unloading the boxes, the setting of the rolling assembly can greatly reduce the friction force, thereby achieving the purpose of easy loading and unloading of the boxes. At the same time, the boxes can be clamped to improve the stability of the device, avoid the risk of the boxes slipping due to free movement, and can take out the boxes arbitrarily according to needs, which can not only realize the overall removal of the boxes, but also realize the partial removal of the boxes in the middle position of the shelf body, which greatly improves the flexibility of the device, saves time, reduces labor costs, improves the efficiency of loading and unloading boxes, and improves the overall work efficiency, especially can meet emergency situations such as rushing deadlines, and achieve smooth delivery.

[0038] When installing the cargo box 4, the cargo box 4 is pushed to roll on the rolling assembly 3 to achieve the installation of each layer of cargo boxes 4; when unloading the cargo box 4, the cargo box 4 of any layer is unloaded, and the cargo box 4 above the corresponding layer is removed at the same time.

[0039] Working principle: When installing the cargo box 4, the palletizing robot is used to place the cargo box 4 on the support assembly 2, and the rolling assembly 3 is used to push the cargo box 4 to a reasonable position of the support assembly 2 until the cargo box 4 contacts the contact assembly 5. Under the action of the transmission assembly 6, the rolling assembly 3 is forced to rotate, so that the cargo box 4 does not roll in the loading direction. When the cargo box 4 contacts the support assembly 2, the gravity of the cargo box 4 causes the support assembly 2 to move downward, so that the cargo box 4 is supported. At the same time, under the action of the inflation assembly 8, the clamping assembly 7 is forced to move. When the cargo box 4 moves completely to the end of the support assembly 2, the palletizing robot is used to completely release the cargo box 4, so that the clamping assembly 7 clamps the side of the cargo box 4. The palletizing robot is used to hold the cargo box 4 to prevent it from rolling freely under the action of the rolling component 3. At this time, the rotating connecting component 11 engages itself, and the installation of each layer of cargo boxes 4 is completed in sequence; when unloading each layer of cargo boxes 4, the air pressure of the clamping component 7 of the corresponding layer is released, and the cargo box 4 of the corresponding layer is pulled outward by the palletizing robot until the rotating connecting component 11 is separated, the supporting component 2 retreats, and the clamping component 7 is forced to retreat, thereby releasing the cargo box 4 until the cargo box 4 is separated from the contact component 5, so that the contact component 5 drives the transmission component 6 to rotate, so that the rolling component 3 rotates to a reasonable position, and then the cargo box 4 of the corresponding layer is quickly pulled out by the palletizing robot to achieve the purpose of fast unloading; when taking out the cargo boxes 4 of any layer and the above cargo boxes 4 at the same time, first The air pressure in the clamping assembly 7 of the corresponding layer is released, so that the cargo box 4 in contact with the stacking robot is released, and the stacking robot supports the cargo box 4 and lifts the corresponding cargo box 4, so that the cargo box 4 moves upward. At the same time, under the action of the rotating connection assembly 11, the sliding assembly 9 moves outward, and the sliding assembly 9 drives the supporting assembly 2 of the upper layer to move. Under the action of the rolling assembly 3, the cargo box 4 of the upper layer has rolling friction. Due to the balanced force on both sides, the cargo box 4 does not move until the cargo box 4 is separated from the supporting assembly 2. At this time, the cargo box 4 of the corresponding layer just contacts the cargo box 4 of the upper layer, completing the removal of the cargo box 4 and the cargo box 4 of the upper layer. And so on, the cargo boxes 4 of any layer and the above cargo boxes 4 are taken out at the same time. And it can take out the cargo box 4 at any layer in the middle position; in summary, the present application is a shelf frame that is easy to load and unload goods. When loading and unloading the cargo box 4, the setting of the rolling component 3 can greatly reduce the friction force, thereby achieving the purpose of easy loading and unloading of the cargo box 4, and at the same time can clamp the cargo box 4, improve the stability of the device, avoid the risk of slipping due to free movement of the cargo box 4, and can take out the cargo box 4 arbitrarily according to demand, not only can the overall removal of the cargo box 4 be achieved, but also the partial removal of the cargo box 4 in the middle position of the shelf body 1 can be achieved, which greatly improves the flexibility of the device, saves time, reduces labor costs, improves the efficiency of loading and unloading the cargo box 4, and improves the overall work efficiency, especially can meet emergency situations such as rushing deadlines, and achieves smooth delivery.

The reset component 10 includes a movable block 1001 arranged on a supporting plate 903, a support rod 1002 is arranged on the shelf body 1, a baffle 1003 is arranged at the end of the support rod 1002, and a reset spring 1004 is arranged between the baffle 1003 and the movable block 1001.

[0049] like Figure 3 and Fig.10 As shown, the present invention is a shelf frame that is easy to load and unload goods. The rotating connection component 11 includes a rotating gear 1101 connected to the shelf body 1 by a bearing, a horizontal spur rack 1102 meshing with the rotating gear 1101 is provided on the supporting plate 903, and a vertical spur rack 1103 meshing with the rotating gear 1101 is provided on the cargo box 4.

[0050] Working principle: When installing the cargo box 4, a single cargo box 4 is placed on the load-bearing plate 204 by using a palletizing robot and the cargo box 4 is pushed. Under the action of the roller 305, the cargo box 4 rolls on the roller 305 to a reasonable position, thereby reducing the friction. When the cargo box 4 contacts the contact plate 503, the cargo box 4 is pushed continuously. The movement of the cargo box 4 drives the movement of the contact plate 503. The contact plate 503 drives the connecting rod 502 to slide on the supporting rod 1 501. Under the interference of the baffle 1 504 and the connecting rod 502, the contact spring 505 is compressed until the cargo box 4 moves. Until it is aligned with the end of the carrying plate 204, the connecting rod 502 drives the transmission spur rack 601 to move, forcing the transmission gear 602 to rotate, thereby causing the rotating rod 301 to rotate, and the rotation of the rotating rod 301 drives the rotating pulley 302 to rotate, and the rotating pulley 302 is driven by the belt 303, so that all the rotating pulleys 302 rotate until the roller 305 rotates at a right angle, so that the direction of the roller 305 changes, so that the cargo box 4 will not roll along the loading direction, and at this time the vertical spur rack 1103 is meshed with the rotating gear 1101;

[0051] Before the vertical spur rack 1103 meshes with the rotating gear 1101, due to the gravity of the cargo box 4 and the cargo inside, the load-bearing plate 204 moves downward under the action of gravity, and the downward movement of the load-bearing plate 204 drives the sliding rod 203 to move downward, so that the sliding rod 203 drives the supporting piston 202 to move downward in the supporting cylinder 201, so that the supporting piston 202 squeezes the gas, forcing the gas to be squeezed, so that the gas enters the clamping cylinder 702, forcing the air pressure in the clamping cylinder 702 to increase, so that the clamping piston 703 moves, and under the action of the guide plate 706, the clamping rod 704 moves, the clamping spring 707 is compressed, and the clamping plate 705 is close to the cargo box 4; when the cargo box 4 moves to the load-bearing plate 204, the load-bearing plate 204 moves downward, so that the support piston 202 squeezes the gas, forcing the gas to squeeze, so that the gas enters the clamping cylinder 702, and the air pressure in the clamping cylinder 702 is increased, so that the clamping piston 703 moves. Before the end of the plate 204, the palletizing robot is used to completely release the cargo box 4. At this time, the carrying plate 204 and the roller 305 support the cargo box 4, and the cargo box 4 is pushed forward again, so that the vertical spur rack 1103 is meshed with the rotating gear 1101, until the cargo box 4 moves to the end of the carrying plate 204, the air pump 801 is started, the solenoid valve 1 805 is opened, and the solenoid valve 2 806 is closed. The gas is filled into the clamping cylinder 702 by using the inflation pipe 802, the connecting pipe 803 and the air guide pipe 804, so that the clamping plate 705 is just in contact with the side wall of the cargo box 4, thereby achieving the clamping effect of the cargo box 4, preventing the cargo box 4 from rolling freely to both sides under the action of the roller 305, and the installation of each layer of the cargo box 4 is completed in sequence;

[0052] When unloading each layer of cargo box 4, the pressure relief valve 708 is used to release the gas in the clamping cylinder 702, so that the clamping piston 703 retreats, driving the clamping rod 704 to retreat, so that the clamping rod 704 drives the clamping plate 705 to retreat, so that the clamping plate 705 is separated from the side wall of the cargo box 4, so that the cargo box 4 is released, and the corresponding layer of cargo box 4 is pulled outward by the palletizing robot until the vertical spur rack 1103 is separated from the rotating gear 1101, and the cargo box 4 is continued to be pulled until the cargo box 4 is separated from the contact plate 503 and the contact spring 50 5 needs to be restored to the original state, so that the contact spring 505 drives the connecting rod 502 to retreat, so that the connecting rod 502 drives the transmission spur rack 601 to retreat, and the transmission gear 602 retreats to the original position, so that the rotating rod 301 retreats and rotates, and under the action of the rotating pulley 302 and the belt 303, the fixed plate 304 rotates and retreats to the original position, so that the roller 305 rotates to the original direction, so that the roller 305 and the unloading direction of the cargo box 4 are consistent, and then the corresponding layer of cargo boxes 4 are quickly pulled out by the palletizing robot to achieve the purpose of rapid unloading;

[0053] When taking out the cargo box 4 of any layer and the above cargo boxes 4 at the same time, first open the pressure relief valve 708 of the corresponding layer, close the solenoid valve 1 805 and the solenoid valve 2 806, release the gas in the clamping cylinder 702, reduce the air pressure, so that the cargo box 4 in contact with the palletizing robot is released, and the palletizing robot supports the cargo box 4 and lifts the corresponding cargo box 4, so that the cargo box 4 moves upward. Since the vertical spur rack 1103 and the rotating gear 1101 are in a meshing state, when the cargo box 4 moves upward and drives the vertical spur rack 1103 to move upward, the rotating gear 1101 rotates, forcing the horizontal spur rack 1102 to move outward. Under the action of the slide groove 901 and the T-shaped slider 902, the support plate 903 moves outward, and the support plate 903 drives the supporting cylinder 201 of the upper layer to move to both sides, forcing the supporting cylinder 201 to drive the sliding rod 203, the supporting spring 205, and the supporting The piston 202 and the supporting plate 204 move outwards. At this time, the roller 305 is located perpendicular to the direction in which the cargo box 4 is installed, forcing the roller 305 to move relative to the cargo box 4 of the upper layer. At this time, the cargo box 4 is subjected to equal friction on both sides, and the force is balanced, so that the roller 305 rolls at the bottom of the cargo box 4 until the cargo box 4 is separated from the supporting plate 204 and the roller 305. At this time, the cargo box 4 of the corresponding layer just contacts the cargo box 4 of the upper layer, so that the stacking robot supports the cargo box 4 and the cargo box 4 of the upper layer, completing the supporting effect of the two cargo boxes 4, and using the stacking robot to take out the two cargo boxes 4, completing the taking out of the cargo box 4 and the cargo box 4 of the upper layer, and so on and so forth, completing the simultaneous taking out of the cargo boxes 4 of any layer and above; at this time, because the stacking robot lifts and pulls out the cargo box 4, it can directly pull out the stacked cargo boxes 4, thereby realizing the taking out action of the cargo box 4 of any layer in the middle position.

When the cargo box 4 moves upward, it forces the supporting plate 903 to move to both sides, so that when the cargo box 4 moves upward, it contacts with the upper cargo box 4, and realizes the operation of the stacking robot on multiple cargo boxes 4, avoiding the supporting plate 903 from hindering the cargo box 4 when the cargo box 4 moves upward, thereby improving the rationality of the device. ;

[0055] In this solution, when loading and unloading cargo boxes 4, the setting of the roller 305 can greatly reduce the friction force, thereby achieving the purpose of easy loading and unloading of cargo boxes 4. At the same time, the cargo box 4 can be clamped to improve the stability of the device, avoid the risk of free movement of the cargo box 4 and slipping, and the cargo box 4 can be taken out arbitrarily according to needs, not only can the entire cargo box 4 be taken out, but also the cargo box 4 in the middle position of the shelf body 1 can be partially taken out. For example, when there are multiple cargo boxes 4, all of them can be taken out from the bottom or the third and fourth layers in the middle can be taken out simultaneously, which greatly improves the flexibility of the device, saves time, reduces labor costs, improves the efficiency of loading and unloading cargo boxes 4, and improves the overall work efficiency, especially to meet emergency situations such as rushing deadlines, achieve smooth delivery, or meet random inspections, etc., and facilitate the selection of cargo boxes 4.
