Specifically, referring to fig. 3, the buffer body 4 includes a first bottom plate 41 fixed to the moving body 1 and a side plate 42 vertically fixed to the first bottom plate. The side plates form an accommodating structure of an internal cavity in a multi-surface surrounding mode. The side panels may be wall structures or shell structures formed from sheet material. The side plate has an opening 43 formed in at least one surface thereof, the opening communicating with the external space. In addition, the buffer main body 4 is further provided with a mounting plate 31 at a position near the top.

The material supporting frame 5 includes a plurality of supporting rods 51 vertically fixed in the buffer main body 4 and at least one set of supporting members 53 fixed on the supporting rods 51. The supporting piece 53 is fixed to the supporting rod 51 at a side far from the opening of the buffer main body 4. When multiple sets of supports 53 are employed, each set of supports 53 forms a buffer location. For example, 4 support rods 51 are provided, the bottom of the support rods 51 is fixed to the first bottom plate, and the top of the support rods 51 is fixed to the mounting plate 31. Each group of the supporting pieces 53 contains 4 supporting pieces 53 in total, the 4 supporting pieces 53 are fixed to the 4 supporting pieces 51, respectively, and the supporting surfaces of the 4 supporting pieces 53 are ensured to be horizontal. At this time, the 4 supports 53 form one buffer position. Of course, it is possible to form the height difference of 4 supporting pieces 53 of each group according to the bottom structure of the buffered material. At this time, the space between the 4 supports 53 forms one transfer passage in the vertical direction.

The transfer module 2 in this embodiment is provided in the buffer main body 4. In particular, the transfer assembly 2 includes a transfer member 26 for supporting material and a transfer mechanism 6 for driving the transfer member 26 to move.

The transfer piece 26 is arranged on the transfer mechanism, and the transfer piece 26 can be driven to move to a preset position through the transfer mechanism to carry out material storage and fetching.

The transfer mechanism 6 includes a lifting mechanism 3 and a translation mechanism 7. The transfer mechanism 6 may adopt a specific structure in which the translation mechanism 3 is disposed on the lifting mechanism 3, or a specific structure in which the lifting mechanism 3 is disposed on the translation mechanism 7, so that the transfer member 26 can be driven by the transfer mechanism to realize a compound motion in the horizontal direction and the vertical direction.

Specifically, in this embodiment, a transfer mechanism in which the translation mechanism 7 is provided on the lifting mechanism 3 will be described in detail. Wherein, the lifting mechanism 3 is arranged in the buffer main body 4. Specifically, the lifting mechanism 3 includes a screw rod 32 provided in the buffer body 4, and a movable nut 33 screwed with the screw rod 32. The screw 32 is vertically disposed, and two ends of the screw are respectively rotatably connected with the first bottom plate and the mounting plate 31. A drive source (not shown) is provided at one end of the screw 32, and the screw 32 is driven to rotate by the drive source. The drive source may be a motor coupled to a drive sprocket. The movable nut 33 is sleeved on the screw rod 32 and is fixedly connected with the translation mechanism. In addition, the inner wall of the side plate near the opening is also symmetrical with a guiding chute 421 in the vertical direction. Correspondingly, the two sides of the translation mechanism 7 are symmetrically provided with guide sliding blocks 71. The guide slider slides in the guide chute, so that the lifting of the translation mechanism can be guided. The driving source can drive the screw rod 32 to rotate, and the movable nut 33 drives the translation mechanism to ascend or descend along the direction of the guide chute 421. Meanwhile, in order to keep the balance of the translation mechanism, two groups of lifting mechanisms 3 may be symmetrically arranged at the position of the opening 43 of the buffer main body 4 to drive the translation mechanism 7 to move up and down stably.

Referring to fig. 4, the translation mechanism 7 includes a second base plate 21 provided on the lifting mechanism 3, and a rack and pinion structure provided on the second base plate 21. The transfer element 26 is disposed on the rack-and-pinion structure, and can drive the transfer element 26 to move horizontally through the rack-and-pinion structure with power input. In addition, the above-mentioned guide slider 71 is fixed to both sides of the second bottom plate 21. Specifically, the second bottom plate 21 is fixedly connected to the movable nut 33. Referring to fig. 5, the rack and pinion structure specifically includes a support plate 25, a driving gear 251, and a first driven gear 252. The support plate 25 is vertically disposed on the second bottom plate 21. The bottom of the transfer piece 26 is in sliding connection with the outer wall of the supporting plate 25. A driving source (not shown) is provided at one side of the driving gear 251, and the driving gear 251 is rotatable by the driving source. The driving source may be a motor connected to a decelerator. A plurality of first driven gears 252 meshed with each other are arranged on one side of the driving gear 251, the first driven gears 252 are rotatably connected with the inner side wall of the supporting plate 25 and are transversely arranged, and the driving gear 251 is meshed with one of the first driven gears 252, so that the driving gear 251 can drive the first driven gears 252 to rotate together. The bottom of the transfer piece 26 is provided with a first rack 261 meshed with the first driven gear 252, and the driving gear 251 is driven to rotate by the driving source, so that the driving gear 251 drives the transfer piece 26 to move through the first driven gear 252.

The rack and pinion configuration described above may also be modified if the cargo is heavy or the transfer member 26 has a large translation distance. Specifically, referring to fig. 6, a fork plate 24 is additionally arranged between the transfer member 26 and the support plate 25, and the bottom of the fork plate 24 is slidably connected with the outer wall of the support plate 25, and the bottom of the transfer member 26 is slidably connected with the outer wall of the fork plate 24. The arrangement of the driving gear 251 and the first driven gear 252 is the same as that of the above-described embodiment, and will not be described again. The bottom of the fork plate 24 is provided with a second rack 242 meshed with the first driven gear 252, so that the driving gear 251 can drive the fork plate 24 to move through the first driven gear 252. The two end positions on the side wall of the fork plate 24 are rotatably connected with a second driven gear 241, a chain is sleeved and meshed on the outer side of the second driven gear 241, and the chain moves in a matching way when the second driven gear 241 rotates. The first rack 261 at the bottom of the transfer member 26 is engaged with the chain. A driving source (not shown) is disposed on the side wall of the fork plate 24 corresponding to one of the second driven gears 241, and the driving source may be a motor connected with a speed reducer. The second driven gear 241 can rotate by the driving source, and the second driven gear 241 can drive the chain to move, thereby driving the transfer element 26 to move.

When the material needs to be cached, the movable body 1 drives the caching component to move to a material storage position. The transfer piece 26 is then removed from the cache body 4 by the transfer mechanism. After the transfer piece 26 bears the materials, the transfer piece 26 is moved into the buffer main body 4 through the transfer mechanism, the transfer piece 26 is driven to be lifted to a height slightly higher than the buffer position to be placed through the lifting mechanism 3, the transfer piece 26 is moved to the position above the buffer position through the translation assembly, and then the transfer piece 26 is driven to descend through the lifting mechanism 3 until the materials are stored on the support piece 53 at the buffer position. The lifting mechanism 3 drives the transfer piece 26 to move down to the lower part of the buffer storage position along the transfer channel, and the transfer piece 26 is moved to the initial position through the translation mechanism. When the buffered material needs to be removed, the moving body 1 drives the buffering component to move to a position where the buffered material needs to be used, and then drives the transfer piece 26 to transfer the buffered material to the outside of the buffering body 4 through the transfer mechanism. The process is opposite to the process of storing the material in the buffer storage position, and will not be described herein. The above-mentioned materials are not limited to workpieces, raw material pieces, carriers for carrying workpieces or raw material pieces, or the like.

In order to enable the material to be stacked in a horizontal direction, in a further embodiment the translation mechanism further comprises first guides 22 provided on both sides of the second bottom plate 21 for guiding in a horizontal direction. Specifically, the positions of two sides of the second bottom plate 21 are vertically provided with side plates, and the distance between the side plates is matched with the width of the material. The first guide members 22 are connected to the end portions of the side plates, and the first guide members 22 extend obliquely outwards, so that the included angle between the two first guide members 22 is an obtuse angle. When the transfer piece 26 carries the material to move to the buffer storage position, if the material is not orderly stacked, the material is firstly contacted with the first guide piece 22, and in the moving process of the material, the first guide piece 22 moves the material along the horizontal direction until the material is orderly stacked. The first guide 22 here may take the form of a guide plate.

In order to make the displacement position of the transfer element 26 accurate, in a further embodiment, a photoelectric sensor 23 is provided on the second base plate 21. The photoelectric sensor 23 is located on the side of the support plate 25, and is capable of detecting whether the transfer piece 26 reaches a specified position.

In order to enable the material to be placed in order in the vertical direction, in a further embodiment the material support 5 further comprises a second guide 52 provided on the support bar 51 for guiding in the vertical direction. The second guides 52 are located near the buffer position, and the distance between the second guides 52 corresponds to the material. The top of the side, contacted with the material, of the second guide piece 52 is provided with a chamfer, when the material is conveyed to the buffer position by the conveying piece 26 through the conveying channel, the material which is not orderly stacked in the vertical direction is contacted with the chamfer first, and the material is orderly stacked in the vertical direction gradually in the moving process. In order that the second guide 52 does not interfere with the entry of the transfer element 26 into the transfer channel, the second guide 52 is shorter in length near the translation mechanism. The second guide 52 may be a vertical guide with an L-shaped end surface, and the L-shaped slot faces the direction of the transfer passage, so that rectangular materials can be stacked when passing through the second guide 52. According to different shapes of materials, arc-shaped, T-shaped and other structures can be adopted.

According to the material conveying device, materials are not required to be manually conveyed to be loaded and unloaded, and the material conveying vehicle is not required to be pushed to be conveyed, so that the labor intensity of staff is reduced, the material taking, unloading and conveying efficiency of the material conveying device is high, and the overall conveying efficiency is improved; through the structural design of the double lead screws 32, the two sides of the transfer assembly 2 are stressed simultaneously, the stress is uniform, and the service life of the structure is prolonged.
