[0041] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0042] The intelligent storage system generally includes a stacker and a container; the stacker is equipped with a fork that can slide up and down to pick up materials from the corresponding storage cells on the container. The stacker drives the fork to move up and down through a synchronous belt. If the synchronous belt is too tight, it will cause increased wear and affect the service life of the synchronous belt; if the synchronous belt is too loose, it is easy to slip, affecting the transmission efficiency.

[0043] Therefore, in the prior art, the stacker lifting synchronous belt tensioning adjustment method is to adjust the tightness of the synchronous belt by adding an external tensioning wheel, but the external tensioning wheel will make the structure of the stacker lifting mechanism more complicated, the cost is high and the adjustment efficiency is low.

[0044] The first embodiment of the present application proposes a transmission mechanism, such as Figures 1 to 3 As shown, the transmission mechanism includes a frame 100, a transmission assembly 200 and an adjustment assembly 300. The transmission assembly 200 adopts a synchronous belt transmission mode. The transmission assembly 200 includes a driving wheel 210, a driven wheel 220, a synchronous belt 230 and a power source 240. The power source 240 is connected to the driving wheel 210 and is used to drive the driving wheel 210 to rotate. The axial directions of the driving wheel 210 and the driven wheel 220 are arranged side by side along a first direction, that is, the axial directions of the driving wheel 210 and the driven wheel 220 are perpendicular to the first direction, and there is an initial axial center distance between the driving wheel 210 and the driven wheel 220 along the first direction. The synchronous belt 230 is wound around the driving wheel 210 and the driven wheel 220, so that the rotation of the driving wheel 210 can drive the driven wheel 220 to rotate.

[0045] Among them, Figure 3 As shown, the driven wheel 220 includes a wheel body 221 and a rotating shaft 222 passing through the wheel body 221, and the wheel body 221 can rotate relative to the rotating shaft 222. The rotating shaft 222 and the frame body 100 are slidably connected along a first direction. Figure 1 and Figure 2In the illustrated embodiment, the frame 100 includes a first plate 120 and a second plate 130 extending along a first direction and arranged side by side with each other, and the first plate 120 and the second plate 130 are respectively provided with a third guide groove 121 extending along the first direction, and the driven wheel 220 is located between the first plate 120 and the second plate 130, and both ends of the rotating shaft 222 of the driven wheel 220 are respectively inserted into the third guide grooves 121 of the two side plates, thereby realizing a sliding connection between the driven wheel 220 and the frame 100 along the first direction.

[0046] The adjustment assembly 300 is used to adjust the tightness of the synchronous belt 230 so that the transmission assembly 200 is in the best transmission state. The adjustment assembly 300 includes a wedge 310 and an adapter 320. It can be understood that the third guide groove 121 can be set through the plate or not. In other embodiments, the frame 100 and the driven wheel 220 can also be slidably connected by the cooperation of the slide groove and the slide rail, which will not be repeated here.

[0047] The wedge block 310 can move relative to the frame 100 along the second direction. It should be explained that the wedge block 310 and the frame 100 can be as follows: Figure 2 The sliding connection shown in FIG. 1 is provided on the top surface of the frame body 100 with a second guide groove 111 extending along the second direction (eg, Figure 5 As shown in FIG. 1 , the second guide groove 111 can guide the movement of the wedge block 310. Alternatively, the wedge block 310 and the frame 100 may not be directly connected, and the wedge block 310 is mounted on the frame 100 through the transmission member 330, and the adapters 320 on both sides clamp the wedge block 310 to guide the wedge block 310.

[0048] The wedge block 310 is provided with a first inclined surface 311, which is inclined relative to the second direction, that is, the distance from the first inclined surface 311 to the top surface of the frame 100 gradually increases or decreases along the second direction. The adapter 320 extends along the first direction, one end of the adapter 320 abuts against the first inclined surface 311, and the other end is connected to the rotating shaft 222, so that the abutment between the first inclined surface 311 and the adapter 320 can convert the movement of the wedge block 310 along the second direction into the movement of the adapter 320 along the first direction.

[0049] The wedge block 310 is driven to move in the second direction, and at the same time, the adapter 320 moves in the first direction due to the abutment of the first inclined surface 311. Since one end of the adapter 320 is connected to the driven wheel 220, the driven wheel 220 slides in the first direction relative to the frame 100 driven by the movement of the adapter 320, and then the axial distance between the driving wheel 210 and the driven wheel 220 increases or decreases. It can be understood that when the axial distance between the driving wheel 210 and the driven wheel 220 increases, the synchronous belt 230 is tighter than before the adjustment. When the axial distance between the driving wheel 210 and the driven wheel 220 increases, the synchronous belt 230 is looser than before the adjustment.

[0050] Based on the above, the transmission mechanism of the present application can adjust the tightness of the synchronous belt 230, so that the tightness of the synchronous belt 230 is adapted to the transmission parameters such as load and rotation speed, thereby improving the service life and transmission efficiency of the synchronous belt transmission mechanism. In addition, the position of the driven wheel 220 is adjusted by moving the driving wedge block 310, thereby achieving the adjustment of the tightness of the synchronous belt 230. Compared with the solution of adding an additional tension wheel in the prior art, the transmission mechanism of the present application has a simpler structure and is more convenient to adjust.

[0051] In some embodiments, Figure 2 and Figure 3 As shown, the adjustment assembly 300 further includes a transmission member 330, the frame 100 includes a mounting seat 140 and a base plate 110, the mounting seat 140 is arranged on the top surface of the base plate 110, and the transmission member 330 is arranged through the two mounting seats 140 and mounted on the frame 100. The transmission member 330 is rotatably connected with the frame 100, and the transmission member 330 is arranged through the wedge block 310 and is threadedly connected with the wedge block 310. When the transmission member 330 is driven to rotate, the wedge block 310 moves along the second direction relative to the transmission member 330. One end of the transmission member 330 is provided with a hexagonal groove adapted to a hexagonal wrench, and the hexagonal wrench can be inserted into the hexagonal groove, and the operator can drive the transmission member 330 to rotate by rotating the hexagonal wrench. Alternatively, the adjustment assembly 300 includes a driving motor, and the output shaft of the driving motor is connected to the transmission member 330 to drive the transmission member 330 to rotate. For this reason, the electric adjustment of the tightness of the synchronous belt 230 can be achieved by controlling the start and stop of the driving motor.

[0052] In some further embodiments, the adjustment assembly 300 has two wedges 310, and correspondingly, two adapters 320 are also provided, and the two adapters 320 are respectively connected to the two ends of the rotating shaft 222 of the driven wheel 220. Figure 3 and Figure 4The two wedge blocks 310 shown can be connected as an integral structure, or the two wedge blocks 310 can be separate components. The first inclined surfaces 311 of the two wedge blocks 310 are arranged in parallel, that is, along the second direction, the distances from the two first inclined surfaces 311 to the substrate 110 are gradually increased or gradually decreased. The external threads on the transmission member 330 have the same rotation direction, so that when the transmission member 330 rotates, the two wedge blocks 310 move in the same direction, and the two adapters 320 respectively abutting against the two wedge blocks 310 move in the same direction.

[0053] In some further embodiments, the adjustment assembly 300 has two wedge blocks 310, which are different from the first inclined surfaces 311 of the two wedge blocks 310 being arranged in parallel. Figure 6 and Figure 7 As shown, the first inclined surfaces 311 of the two wedge blocks 310 are arranged facing each other or facing each other, that is, the two first inclined surfaces 311 are arranged to intersect, that is, along the second direction, the distance between one of the two first inclined surfaces 311 and the substrate 110 gradually increases, and the distance between the other and the substrate 110 gradually decreases. Correspondingly, the outer peripheral surface of the transmission member 330 is provided with two thread segments with opposite rotation directions, and the two wedge blocks 310 are respectively connected to the thread segments with different rotation directions, so that when the transmission member 330 rotates, the two wedge blocks 310 move away from each other or towards each other, that is, one moves in the second direction and the other moves in the opposite direction of the second direction. Since the first inclined surfaces 311 are in opposite directions, the two adapters 320 respectively contacting the two wedge blocks 310 still maintain the same movement direction, that is, the two adapters 320 both move in the first direction or in the opposite direction of the first direction.

[0054] In the above embodiment, the transmission member 330 is further provided with a force-applying portion 331, and the force-applying portion 331 is provided with at least two abutting planes 3311 along the circumferential direction, and the abutting planes 3311 can be used to abut against the wrench, so as to provide the wrench with a force-applying point that is not easy to slide, thereby facilitating the wrench to drive the transmission member 330 to rotate. Further, the abutting planes 3311 are arranged parallel to each other.

[0055] In such Figure 7 In the embodiment shown, a planar groove is provided on the outer circumference of the force-applying portion 331, thereby forming an abutment plane 3311 for abutting against a wrench. In other embodiments, the force-applying portion 331 can be designed as a prism structure such as a quadrangular prism, a hexagonal prism or an octagonal prism, thereby having an abutment plane 3311 that is convenient for the wrench to clamp.

[0056] The force applying portion 331 is disposed between the two threaded sections, and the two wedge blocks 310 are respectively located on both sides of the force applying portion 331, so as to balance the force of the transmission member 330. Figure 5As shown in FIG. 1 , the avoidance groove 113 is arranged corresponding to the position of the force-applying portion 331 to facilitate the insertion of the wrench and the rotation of the wrench.

[0057] In some embodiments, the adjustment assembly 300 further includes a locking member 340, which is connected to one end of the transmission member 330 and is threadedly connected to the transmission member 330. The locking member 340 has a locked state and a released state, and the locked state and the released state can be switched by rotating the locking member 340. In the locked state, the locking member 340 abuts against the frame 100 and limits the rotation of the transmission member 330; in the released state, the locking member 340 is separated from the frame 100, and the transmission member 330 can rotate relative to the frame 100. Figure 3 In the embodiment shown, the left end of the transmission member 330 is a hexagonal hole for inserting a hexagonal wrench, and the right end of the transmission member 330 is connected to a locking member 340 for locking the transmission member 330. Figure 7 In the illustrated embodiment, since a force-applying portion 331 for contacting with a wrench is disposed in the middle of the transmission member 330 , both ends of the transmission member 330 can be connected to locking members 340 for more secure locking.

[0058] Different from the above-mentioned embodiment in which the transmission member 330 is threadedly connected to the wedge block 310, in other embodiments, only one mounting seat 140 may be provided on the frame 100, and the transmission member 330 is passed through the mounting seat 140 and threadedly connected to the mounting seat 140, so that when the transmission member 330 rotates, the transmission member 330 can move relative to the mounting seat 140. One end of the transmission member 330 abuts against the wedge block 310, so that the movement of the transmission member 330 can push the wedge block 310 to move.

[0059] In some embodiments, Figure 3 and Figure 7 As shown, the adapter 320 includes a roller 322 abutting against the first inclined surface 311, and a first guide groove 3111 is provided on the first inclined surface 311. The first guide groove 3111 extends along the moving path of the roller 322, and the roller 322 is at least partially located in the first guide groove 3111, so that the groove wall of the guide groove can guide the movement of the roller 322 to prevent the adapter 320 from detaching from the first inclined surface 311 during the moving abutment process.

[0060] In some embodiments, each adapter 320 includes two adapter arms 321 extending along the first direction, and the two adapter arms 321 are spaced apart to form a guide space, and the wedge block 310 is at least partially located in the guide space and guided by the adapter arms 321 on both sides. Figure 3 In the illustrated embodiment, the transfer arms 321 are respectively located on both sides of the moving direction of the wedge block 310 , so as to clamp the wedge block 310 between the two transfer arms 321 .

[0061] Furthermore, the frame 100 is provided with a second guide groove 111 extending along the second direction, the wedge block 310 is at least partially located in the second guide groove 111, and the groove wall of the second guide groove 111 guides the movement of the wedge block 310. Figure 5 In the illustrated embodiment, the second guide groove 111 is disposed on the top surface of the substrate 110, and the bottom end of the wedge block 310 is inserted into the second guide groove 111. On the one hand, the bottom of the second guide groove 111 supports the wedge block 310, and on the other hand, the groove wall of the second guide groove 111 can guide the movement of the wedge block 310.

[0062] like Figure 5 As shown, the frame 100 is also provided with a guide hole 112 penetrating along the first direction, and the transfer arm 321 is passed through the guide hole 112. The hole wall of the guide hole 112 guides the transfer arm 321 to move. It can be understood that the transfer arm 321 can be moved as follows. Figure 3 Movement in the first direction shown.

[0063] The second embodiment of the present application proposes a stacker, including the transmission mechanism mentioned in the above embodiment, the tightness of the synchronous belt 230 of the stacker can be adjusted, so that it can have a longer service life and higher transmission efficiency. In addition, the structure of the adjustment component 300 is relatively simple, low in cost, and high in adjustment efficiency.

[0064] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
