Description

Technical Field

[0001] The present invention relates to the technical field of stereoscopic warehouses, and particularly to an anti-falling device for pallets in a stereoscopic warehouse. Background Art

[0002] A stereoscopic warehouse is a warehouse that uses high-level shelves to store goods, mainly with a roadway stacker crane, and combines computer management and control technologies to achieve automatic access to goods. It breaks through the limitations of traditional warehouses in terms of space utilization and goods access efficiency, and is an important part of modern logistics systems. The high-level shelves are the main structure of the stereoscopic warehouse, usually made of strong materials such as steel. When stacking goods, in order to avoid the situation of goods scattering, the goods on the pallet are generally wrapped with packaging film, so that the goods on the pallet form a whole and will not scatter. When wrapping, the goods and the pallet are generally in a non-fixed state, which can facilitate the rapid separation of the goods and the pallet. When the pallet is placed on the high-level shelf, it is mostly limited by a simple limit pin, which can prevent the pallet from sliding in the horizontal direction. However, when the shelf is subjected to vertical or oblique vibrations, it is almost impossible to prevent the pallet from falling off the shelf. At the same time, when the shelf vibrates, the non-fixed goods will move on the pallet, and the vibration may cause the goods to slide off the pallet. Especially when the pallet itself also shakes or moves, the possibility of the goods falling will increase greatly, which will endanger the safety of warehouse workers, and it is also difficult to clean up the fallen goods debris, which will affect the normal operation of the warehouse.

Specific embodiments

[0023] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the drawings in the specification.

[0024] In the following description, many specific details are set forth to facilitate a thorough understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0025] Second, the "one embodiment" or "embodiment" referred to herein means a specific feature, structure or characteristic that may be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive with other embodiments.

[0026] Embodiment 1 Referring to Figures 1-6 , which is the first embodiment of the present invention. This embodiment provides a three-dimensional warehouse pallet anti-falling device. The three-dimensional warehouse pallet anti-falling device includes a shelf 101.

[0027] The shelf 101 is a high-rise shelf placed inside the warehouse, and a stacker is equipped inside the warehouse for stacking pallets on the shelf 101 or removing the pallets on the shelf 101. This is the prior art, so it is abbreviated in this solution and will not be described in detail. Those skilled in the art can clearly understand the working principle.

[0028] Specifically, the anti-falling component 200 is arranged on the shelf 101 and includes a binding strap 201. The binding strap 201 is arranged on the shelf 101. A fixed cylinder 202 is arranged on one side of the shelf 101. A winding roller 203 is rotatably connected inside the fixed cylinder 202 through a bearing. The binding strap 201 is wound around the outside of the winding roller 203, and one end is fixed to the binding strap 201. The other end of the binding strap 201 is fixed with a counterweight 204. A positioning frame 205 is fixed on one side of the shelf 101. A limiting plate 206 is inserted on one side of the positioning frame 205, and the limiting plate 206 cooperates with the counterweight 204.

[0029] There are multiple groups of anti-falling components 200, which are respectively arranged on each layer of the shelf 101. The binding strap 201 is in an L shape in the initial state, so that when the pallet is placed on the shelf 101, it will not be blocked by the binding strap 201. The counterweight 204 has a certain weight to drive the binding strap 201 to move downward, and the limiting plate 206 is movably connected inside the positioning frame 205.

[0030] First, the goods are wrapped by a packaging film, and then the goods are placed on top of the pallet. At this time, the pallet can be placed on the shelf 101 by a stacker. At this time, the winding roller 203 will rotate and unwind the binding strap 201. After unwinding, the binding strap 201 will move downward under the weight of the counterweight 204. When the counterweight 204 moves downward into the positioning frame 205, the limiting plate 206 will be stuck on the top of the counterweight 204 and limit the counterweight 204 so that it cannot be separated from the positioning frame 205. At this time, the goods can be fixed to the pallet by the binding strap 201, so that they can be stably placed on the shelf 101, avoiding the situation that the goods and the pallet will be displaced when the shelf 101 vibrates, thus there is a risk of falling, and it can provide a stable connection between the goods and the pallet, avoiding the displacement of the goods on the pallet, so that when the stacker removes the pallet, the center of gravity of the pallet will shift, causing the pallet to tip over.

[0031] Embodiment 2 Refer to Figures 1-6 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0032] Specifically, a motor 207 is fixed on one side of the fixed cylinder 202, and the output shaft of the motor 207 is fixed to the winding roller 203.

[0033] The motor 207 is used to drive the winding roller 203 to rotate.

[0034] Specifically, a positioning plate 206-1 is fixed to the bottom of the limiting plate 206, and a positioning column 206-2 is fixed to the positioning frame 205, and the positioning column 206-2 is movably connected inside the positioning plate 206-1.

[0035] Through the cooperation of the positioning plate 206-1 and the positioning column 206-2, it is used to support and position the limiting plate 206 to avoid the situation that it will fall when it moves outside the positioning frame 205.

[0036] Specifically, a fixing block 206-3 is fixed to the end of the positioning column 206-2, and a spring 206-4 is sleeved outside the positioning column 206-2, and both ends of the spring 206-4 are fixed to the fixing block 206-3 and the positioning frame 205 respectively.

[0037] The fixing block 206-3 is used to fix the spring 206-4. When the limiting plate 206 moves outward from the positioning frame 205, it will drive the positioning plate 206-1 to squeeze the spring 206-4. After the counterweight 204 enters the inside of the positioning frame 205, at this time, the spring 206-4 can apply a thrust to the positioning plate 206-1, and drive the limiting plate 206 to move into the positioning frame 205 through the positioning plate 206-1, so that the limiting plate 206 contacts the top of the counterweight 204, thereby restricting the counterweight 204 and making it unable to move. Furthermore, the strap 201 can provide stable fixation for the goods and the pallet, avoiding the situation that the strap 201 loosens when the two shake.

[0038] Specifically, the anti-falling component 200 further includes a pushing member 208, which includes a connecting rod 208a. The connecting rod 208a is fixed to the bottom of the positioning plate 206-1, and a push rod 208b is fixed to one side of the connecting rod 208a.

[0039] When the push rod 208b moves, it will drive the connecting rod 208a to move, and drive the positioning plate 206-1 to move through the connecting rod 208a. In this way, the limiting plate 206 can be driven by the positioning plate 206-1 to move outward from the positioning frame 205.

[0040] Specifically, the inner side of the shelf 101 is rotatably connected with a stress plate 208c through a hinge plate. A rotating column 208d is fixed inside the stress plate 208c, and a push plate 208e is fixed to the outside of the rotating column 208d. One side of the push plate 208e contacts the push rod 208b.

[0041] Both the stress plate 208c and the push plate 208e are inclined. The stress plate 208c is inclined upward, and the push plate 208e is inclined downward. The stress plate 208c is located beside the center of the shelf 101.

[0042] When the stacker drives the pallet to be stacked inside the shelf 101, the fork of the stacker will contact the stress plate 208c and push the stress plate 208c to rotate. When the stress plate 208c rotates, it will drive the push plate 208e to rotate downward through the rotating column 208d. At this time, the push plate 208e can be used to push the push rod 208b to move, so that the limiting plate 206 can move outward from the positioning frame 205. At this time, the motor 207 can be started to unwind the strap 201, and then the fixation of the pallet and the goods is completed.

[0043] When the fork of the stacker moves out from the bottom of the pallet and separates from the stress plate 208c, the spring 206-4 can apply a thrust to the positioning plate 206-1 to drive the limiting plate 206 to move.

[0044] When it is necessary to pick up the pallet and the goods, when the fork arm of the stacker inserts into the bottom of the pallet, it will push the force-bearing plate 208c to rotate again, and drive the push plate 208e and the push rod 208b to move through the force-bearing plate 208c, so that the limit plate 206 moves outward to the outside of the positioning frame 205, thereby releasing the restriction on the counterweight 204, and then driving the winding roller 203 by the motor 207 to wind the binding strap 201.

[0045] Embodiment 3 Refer to Figures 1-6 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0046] Specifically, a stable frame 208f is fixed at the bottom of the shelf 101, and the push rod 208b is movably connected inside the stable frame 208f.

[0047] The stable frame 208f is used to support and position the push rod 208b.

[0048] Specifically, a stable frame 209 is fixed on the shelf 101, and the binding strap 201 is movably connected inside the stable frame 209. There are two stable frames 209, which are respectively located on both sides of the bottom of the shelf 101.

[0049] The stable frame 209 is used to support and position the binding strap 201 to prevent the overall binding strap 201 from falling downward.

[0050] Specifically, baffles 210 are fixed on the outer side of the winding roller 203. There are two baffles 210, which are respectively located on both sides of the binding strap 201 and are used to position the binding strap 201.

[0051] Specifically, an inclined tie rod 101-1 is fixed on the shelf 101.

[0052] The inclined tie rod 101-1 is used to improve the stability of the shelf 101 itself.

[0053] During use, first wrap the goods with a packaging film, and then place the goods on the top of the pallet. At this time, the pallet can be placed on the shelf 101 by the stacker. When the stacker drives the pallet to be stacked inside the shelf 101, the fork arm of the stacker will contact the force-bearing plate 208c and push the force-bearing plate 208c to rotate. When the force-bearing plate 208c rotates, it will drive the push plate 208e to rotate downward through the rotating column 208d. At this time, the push plate 208e can be used to push the push rod 208b to move. When the push rod 208b moves, it will drive the connecting rod 208a to move, and drive the positioning plate 206-1 to move through the connecting rod 208a, so that the limit plate 206 can be driven by the positioning plate 206-1 to move outward to the outside of the positioning frame 205.

[0054] At this time, the motor 207 starts to drive the winding roller 203 to rotate, and unwind the binding strap 201. After the binding strap 201 is unwound, it will move downward under the weight of the counterweight 204. When the counterweight 204 moves downward into the positioning frame 205 and the fork arm of the stacker is removed from the bottom of the pallet, the spring 206-4 can apply a thrust to the positioning plate 206-1, and drive the limiting plate 206 to move into the positioning frame 205 through the positioning plate 206-1, so that the limiting plate 206 contacts the top of the counterweight 204, thereby restricting the counterweight 204 from moving, and further enabling the binding strap 201 to provide stable fixation for the goods and the pallet, avoiding the situation that the binding strap 201 becomes loose when the two shake.

[0055] When it is necessary to take the pallet and the goods, when the fork arm of the stacker is inserted into the bottom of the pallet, it will push the force-receiving plate 208c to rotate again, and drive the push plate 208e and the push rod 208b to move through the force-receiving plate 208c, so that the limiting plate 206 moves outward from the positioning frame 205, thereby releasing the restriction on the counterweight 204. Then, the motor 207 drives the winding roller 203 to wind the binding strap 201. When the binding strap 201 is separated from the side of the goods, the pallet can be moved outwards.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
