Referring to fig. 1 to 3, an embodiment of the present invention provides a loading and unloading system 1, which includes a loading and unloading station, a recycling station, and a material storage station. The loading and unloading system 1 comprises a recovery device 10, a storage device 20 and a loading and unloading device 30.

The recycling device 10 is arranged at a recycling station and comprises a recycling spool 11 for receiving empty rolls (see fig. 10). A magazine 20 is arranged at the magazine station and comprises a magazine shaft 22 for storing full rolls (see fig. 7).

The loading and unloading device 30 includes a moving assembly 31 and an loading and unloading assembly 32, wherein the moving assembly 31 includes a driving mechanism 310 and a mounting seat 312. Drive mechanism 310 is drivingly coupled to mount 312 to drive mount 312 for movement. The loading and unloading assembly 32 includes a transfer shaft 321a and a pushing mechanism 321b both mounted on the mounting seat 312.

The transfer shaft 321a moves to a loading/unloading station, a recycling station, or a storing station along with the mounting base 312. When the transfer shaft 321a moves to the loading and unloading station along with the mounting seat 312, the transfer shaft 321a is axially butted with the unreeling shaft 101 of the unreeling device 100; when the transfer material shaft 321a moves to the recovery station along with the mounting seat 312, the transfer material shaft 321a is axially butted with the recovery material shaft 11; when the transfer shaft 321a moves to the magazine station along with the mounting seat 312, the transfer shaft 321a is axially butted against the magazine shaft 22. The pushing mechanism 321b is used to provide pushing force for the empty roll or the full roll to move onto the transfer shaft 321a or to withdraw from the transfer shaft 321a in the axial direction. Alternatively, the driving mechanism 310 may be an electric cylinder or a lead screw module, etc.

In the feeding and discharging system 1, when the material roll on the unwinding shaft 101 is completely unwound and an empty material roll on the unwinding shaft 101 needs to be replaced by a full material roll, firstly, the middle transferring shaft 321a moves to the feeding and discharging station along with the mounting seat 312 under the driving of the moving assembly 31, and is butted with the unwinding shaft 101 located at the feeding and discharging station. The pushing mechanism 321b pushes the empty roll on the unwinding shaft 101 to the transfer shaft 321 a. Then, under the driving of the moving assembly 31, the transfer shaft 321a moves to the recycling station along with the mounting seat 312, and is axially abutted with the recycled material shaft 11 located at the recycling station. The pushing mechanism 321b pushes the empty material roll on the intermediate material transferring shaft 321a to the recycling material shaft 11, so that the blanking of the empty material roll is realized. Then, under the driving of the moving assembly 31, the transfer shaft 321a moves to the magazine station along with the mounting seat 312, and is axially abutted with the magazine shaft 22 located at the magazine station. The pushing mechanism 321b pushes the full roll on the storage shaft 22 to the transfer shaft 321 a. Then, under the driving of the moving assembly 31, the transfer shaft 321a moves to the loading and unloading station along with the mounting seat 312, and is axially abutted with the unreeling shaft 101 located at the loading and unloading station. The pushing mechanism 321b pushes the full material roll on the intermediate material transferring shaft 321a to the unwinding shaft 101, so that the full material roll is fed.

So, usable unloading system 1 of going up carries out the unloading of empty material book and the material loading of full material book to unreeling axle 101, can carry out automatic unloading of going up at any time, need not to avoid frequent going on artifical unloading and a plurality of full material of installation on unreeling axle 101 for unreeling axle 101 can not adopt the comparatively complicated slip shaft of structure, is favorable to simplifying the structure, and unreeling axle 101's load reduces, is favorable to guaranteeing to rectify the response rapidly.

In the embodiment, the recovery station is arranged between the material storage station and the feeding and discharging station. In this way, when changing the reel, the transfer shaft 321a is first moved to the loading/unloading station to take off the empty reel on the unwinding shaft 101. Then moves to a recovery station and pushes the empty coil onto a recovery spool 11. Then, the roll is moved forward to the stock station (without turning back), and the full roll on the stock shaft 22 is pushed to the transfer shaft 321 a. Then, the transfer shaft 321a is turned back to the loading/unloading station, and the full roll is pushed onto the unwinding shaft 101. Therefore, the moving distance of the material transferring shaft 321a in one roll change is short, and the roll change efficiency is improved.

Referring to fig. 2 to 5, in an embodiment of the present invention, the pushing mechanism 321b includes a telescopic structure (not shown), a telescopic driving structure 322, and a pushing structure 324. The telescopic structure has a mating end connected to the mounting seat 312, and a telescopic end extending and contracting along the axial direction of the material transferring shaft 321a relative to the mating end. The telescopic driving structure 322 is installed on the mounting base 312 and is in transmission connection with the telescopic structure to drive the telescopic end of the telescopic structure to extend and retract along the axial direction of the material transferring shaft 321a relative to the mating end. The pushing structure 324 is mounted to the telescopic end to push the empty roll or the full roll during the axial movement of the telescopic end along the transferring shaft 321 a.

Therefore, the telescopic driving structure 322 is used to drive the telescopic end to extend and retract along the axial direction of the transfer shaft 321a relative to the mating end, so as to drive the pushing structure 324 to move along the axial direction of the transfer shaft 321a, and further push the empty material roll or the full material roll to move along the axial direction onto the transfer shaft 321a or to exit from the transfer shaft 321a, thereby realizing the loading or unloading.

In some embodiments, the telescopic structure includes a plurality of link units 323 sequentially connected in a first direction parallel to the axial direction of the material transferring shaft 321a, and the telescopic driving structure 322 is drivingly connected to the link unit 323 at one end of the first direction to drive the link unit 323 to extend and retract in the first direction and drive each link unit 323 to extend and retract in the first direction synchronously. The pushing structure 324 is connected to the link units 323 at the other end in the first direction, so that each link unit 323 is driven by stretching in the first direction to move back and forth in the first direction, thereby pushing an empty roll or a full roll. In this way, the moving and pushing of the pushing structure 324 along the first direction is realized by adopting the extension and retraction of each connecting rod unit 323, so that the moving response of the pushing structure 324 is rapid, the pushing speed is high, the structure is compact, and the improvement of the space utilization rate is facilitated.

In an embodiment, the telescopic structure further includes a first hinge seat a, a second hinge seat B, a third hinge seat C, a fourth hinge seat D, and a mounting plate 3233, and each link unit 323 includes a first link 3231 and a second link 3232 that are cross-hinged.

In each two adjacent link units 323, the corresponding ends of the first link 3231 of any one link unit 323 and the second link 3232 of another link unit 323 are hinged, so that when the first link 3231 and the second link 3232 of any one link unit 323 rotate around the hinge point, the first link 3231 and the second link 3232 of the other link unit 323 are driven to rotate around the hinge point, and further, the length of each link unit 323 in the first direction is synchronously lengthened or shortened.

An end portion of the first link 3231 and an end portion of the second link 3232 at one end in the first direction are hinged to the first hinge seat a and the second hinge seat B, respectively. The first and second hinge bases a and B are connected to the telescopic driving structure 322 to be driven by the telescopic driving structure 322 to move at least one of them toward or away from the other one along the second direction. Wherein the second direction is perpendicular to the first direction.

An end of the first link 3231 and an end of the second link 3232 at the other end in the first direction are hinged to the third hinge base C and the fourth hinge base D, respectively. The third hinge seat C and the fourth hinge seat D are disposed on the mounting plate 3233, and at least one of the third hinge seat C and the fourth hinge seat D can move toward or away from the other in the second direction. The pusher structure 324 is mounted on the mounting plate 3233 so as to be reciprocated in the first direction by the respective link units 323. It will be appreciated that the first and second hinge seats a and B serve as mating ends of the telescopic structure and the mounting plate 3233 serves as a telescopic end of the telescopic structure.

Thus, when the pushing structure 324 needs to be driven to move along the first direction to push an empty roll or a full roll, the telescopic driving structure 322 drives the first hinge seat a and the second hinge seat B to approach or separate from each other along the second direction, so that the first connecting rod 3231 and the second connecting rod 3232 of the corresponding connecting rod unit 323 rotate around the hinge point of the first hinge seat a and the second hinge seat B, and drive the first connecting rod 3231 and the second connecting rod 3232 of each other connecting rod unit 323 to rotate around the hinge point of the first hinge seat a and the second hinge seat B in the same direction, so that each connecting rod unit 323 synchronously extends or shortens in the first direction, that is, the stretching in the first direction is realized, and the pushing structure 324 mounted on the mounting plate 3233 is driven to push the empty roll or the full roll along the first direction. That is, the link units 323 are interlocked to realize the rapid movement of the pusher 324 mounted to the mounting plate 3233 in the first direction, and thus the mechanism is simple and operates stably and reliably.

Specifically to the embodiment shown in fig. 3, the telescopic structure includes two link units 323, and for convenience of description, the two link units 323 are named a first link unit 323a and a second link unit 323b, respectively. Each first link 3231 includes first and second opposing hinged ends a1 and a2, and each second link 3232 includes third and fourth opposing hinged ends a3 and a 4. The first links 3231 of the two link units 323 are arranged in parallel with each other, and the second links 3232 of the two link units 323 are arranged in parallel with each other. The first hinge end a1 of the first link 3231 of the first link unit 323a is hinged to the first hinge seat a, the second hinge end a2 of the first link 3231 of the first link unit 323a is hinged to the third hinge end a3 of the second link 3232 of the second link unit 323B, the third hinge end a3 of the second link 3232 of the first link unit 323a is hinged to the second hinge seat B, and the fourth hinge end a4 of the second link 3232 of the first link unit 323a is hinged to the first hinge end a1 of the first link 3231 of the second link unit 323B. The second hinge end a2 of the first link 3231 of the second link unit 323b is hinged with the fourth hinge base D, and the fourth hinge end a4 of the second link 3232 of the second link unit 323b is hinged with the third hinge base C.

Thus, when the pushing structure 324 needs to be driven to move along the first direction to push an empty roll or a full roll, the telescopic driving structure 322 drives the first hinge seat a and the second hinge seat B to approach or separate from each other along the second direction, so that the first connecting rod 3231 and the second connecting rod 3232 of the first connecting rod unit 323a rotate around a hinge point between the middle parts of the first connecting rod and the second connecting rod, and the first connecting rod 3231 and the second connecting rod 3232 of the second connecting rod unit 323B are driven to rotate around the hinge point between the middle parts of the first connecting rod and the second connecting rod 3232, and further the mounting plate 3233 and the pushing structure 324 mounted on the mounting plate 3233 are driven to move in the first direction, and the pushing structure 324 pushes materials.

It should be noted that the telescopic structure is not limited to only include two link units 323, and in other embodiments, the telescopic structure may include more than two link units 323, which is not limited herein.

The retractable driving member 3221 is installed on the mounting seat 312 and is in transmission connection with the second hinge seat B to drive the second hinge seat B to approach or depart from the first hinge seat a along the second direction. Alternatively, the telescopic drive 3221 may be a pneumatic cylinder.

Further, a first sliding block (not shown) is arranged on the second hinged seat B, a first sliding rail 3121 which lengthways extends along the second direction is arranged on the mounting seat 312, and the first sliding block is in sliding fit with the first sliding rail 3121, so that the second hinged seat B can move along the second direction by the sliding of the first sliding block along the first sliding rail 3121, and the second hinged seat B can move more stably and reliably.

Specifically, in the embodiment, the third hinge base C and the fourth hinge base D are disposed on the mounting plate 3233 along the second direction, the third hinge base C is fixedly connected to the mounting plate 3233, and the fourth hinge base D is movably connected to the mounting plate 3233 along the second direction, so that the fourth hinge base D can be close to or far from the third hinge base C along the second direction to adapt to the telescopic action of the link unit 323 connected to the third hinge base C and the fourth hinge base D.

Further, a second sliding block a6 is disposed on the fourth hinged seat D, a second sliding rail a5 extending lengthwise along the second direction is disposed on the mounting plate 3233, and the second sliding block a6 is in sliding fit with the second sliding rail a5, so that the fourth hinged seat D moves along the second direction by the sliding of the second sliding block a6 along the second sliding rail a5, and the fourth hinged seat D moves more stably and reliably.

When an empty or full roll is pushed into position, the extension driver 3242 drives the pusher 3243 to retract to its initial position. Alternatively, the extension driver 3242 may be a pneumatic cylinder.

Specifically, the pusher 3243 is movably connected to the mounting plate 3233, and the extension driving member 3242 is mounted to the mounting plate 3233 and drivingly connected to the pusher 3243 to drive the pusher 3243 to extend or retract toward the middle transferring shaft 321 a.

One end of the pull rod 122 is connected to the guide seat 121, and the other end of the pull rod 122 penetrates through the abutting end 115 of the reclaimed material shaft 11. Thus, after the empty roll on the recycling shaft 11 is full, the pull rod 122 can be pulled outwards to penetrate through one end of the butt joint end 115, so that the guide seat 121 drives the shifting block F to push all the empty rolls on the recycling shaft 11 out of the butt joint end 115, and unloading of the empty rolls on the recycling shaft 11 is achieved.

Further, a handle 124 is connected to an end of the pull rod 122 extending out of the docking end 115 for being held by an operator. When the empty roll on the recovery shaft 11 is full and needs to be unloaded, the operator holds the handle 124 and pulls the pull rod 122 outward, so as to drive the shifting block F on the guide seat 121 to push the empty roll out of the butt end 115.

In the embodiment, the discharging assembly 12 further comprises a guiding rod 123 fixedly connected inside the recycling bin 11, and the axial direction of the guiding rod 123 is parallel to the axial direction of the recycling bin 11. The guide seat 121 is provided with a guide hole (not shown), and the guide rod 123 is inserted through the guide hole and is in sliding fit with the guide hole. In this way, the guide rod 123 guides the movement of the guide holder 121 in the axial direction of the reclaimed material shaft 11.

Further, the butt end 115 of the reclaimed material axle 11 is provided with a second end cap 113, and the second end cap 113 is used for plugging the butt end 115. An end of the guide rod 123 facing the docking end 115 may be fixedly attached to the second end cap 113. The second end cap 113 is provided with a through hole (not shown) for the pull rod 122 to pass through, so that one end of the pull rod 122 passes through the through hole to the outside of the recycling bin 11.

In particular embodiments, the reclaimed material axle 11 also includes a connection end 114 opposite the butt end 115. The discharging assembly 12 further comprises a magnetic attracting member 125, wherein the magnetic attracting member 125 is mounted on the connecting end 114 of the recycling material shaft 11 and is used for attracting the guide seat 121. Thus, when unloading of the empty material roll on the recovery material shaft 11 is completed, the operator returns the push-pull rod 122 to the recovery material shaft 11, so that the guide seat 121 is reset to the connection end 114 of the recovery material shaft 11, and is attracted and fixed by the magnetic attraction piece 125, thereby effectively preventing the guide seat 121 from moving axially due to vibration and other reasons when the empty material roll is not required to be unloaded. Alternatively, the magnetic attraction member 125 may be a magnet, an electromagnet, or the like, and is not limited herein.

In the embodiment, the recycling device 10 further includes a first base, and the connecting end 114 of the recycling material shaft 11 is fixedly connected to the first base.

Thus, when the sensor 131 senses the test piece 132, it indicates that the guide seat 121 has moved to the connection end 114, and the empty roll on the transfer spool 321a can be pushed onto the recovery spool 11. Alternatively, the sensor 131 may be a proximity sensor and the test piece 132 may be a rod. It is understood that the sensor 131 is not limited to being mounted on the first base, and the sensor 131 is not limited thereto as long as the sensor 131 is disposed opposite to the connection end 114 of the recovery material shaft 11 to ensure that the test piece 132 moved to the connection end 114 with the guide block 121 can be sensed.

In the embodiment, the recovery shaft 11 and the first base are provided with fool-proof structures to prevent the recovery shaft 11 from being installed and dislocated.
