It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0031] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0032] like Figure 1 , 2 As shown, this utility model provides a material tray switching device, including a stacking mechanism 1, a first driving mechanism 2, and a material tray operating mechanism 3; the stacking mechanism 1 includes a mounting frame 11, a first material tray storage unit 12, and a second material tray storage unit 13; the mounting frame 11 has a material transfer space 111; the first material tray storage unit 12 and the second material tray storage unit 13 are sequentially arranged on the mounting frame 11 along a first direction; the first material tray storage unit 12 has a first storage area 121 communicating with the material transfer space 111; the second material tray storage unit 13 has a first storage area 121 communicating with the material transfer space 111. The second storage area 131; the first driving mechanism 2 is used to drive the tray operating mechanism 3 to enter or exit the transfer space 111 in a first direction; the tray operating mechanism 3 includes a lifting device 31 and a pallet 32 ​​connected to the telescopic end of the lifting device 31; when the tray operating mechanism 3 is in the first position of the transfer space 111, the lifting device 31 is used to drive the pallet 32 ​​to enter or exit the first storage area 121; when the tray operating mechanism 3 is in the second position of the transfer space 111, the lifting device 31 is used to drive the pallet 32 ​​to enter or exit the second storage area 131.

[0033] Specifically, such as Figure 1 , 2As shown, the mounting frame 11 has a material transfer space 111, with inlets at both the left and upper ends of the mounting frame 11. A first tray storage unit 12 and a second tray storage unit 13 are sequentially arranged on the top of the mounting frame 11 along a first direction (i.e., the X-axis direction). The first tray storage unit 12 can be used to store a tray 6 containing a load. The second tray storage unit 13 can be used to store an empty tray 6. The first tray storage unit 12 has a first storage area 121 communicating with the material transfer space 111. The second tray storage unit 13 has a second storage area 131 communicating with the material transfer space 111. The first drive mechanism 2 is used to drive the tray operation mechanism 3 to enter or exit the material transfer space 111 along the X-axis direction.

[0034] like Figure 3 , 4 As shown, the tray operating mechanism 3 includes a lifting device 31 and a pallet 32 ​​connected to the telescopic end of the lifting device 31. Thus, when the tray operating mechanism 3 is in the first position of the transfer space 111, the lifting device 31 can drive the pallet 32 ​​to send the loaded tray 6 into the first storage area 121. After the loaded tray 6 is stored, the lifting device 31 can drive the pallet 32 ​​to exit the first storage area 121. When the tray operating mechanism 3 is in the second position of the transfer space 111, the lifting device 31 drives the pallet 32 ​​into the second storage area 131. After the pallet 32 ​​receives an empty tray 6, the lifting device 31 can drive the pallet 32 ​​with the empty tray 6 to exit the first storage area 121. In summary, the material tray switching device of this utility model can realize the storage and retrieval of the material tray 6 in the first storage area 121 and the second storage area 131 through the cooperation of the first drive mechanism 2 and the material tray operation mechanism 3. Compared with the existing complex material tray switching device, it effectively reduces the number of lifting devices 31, reduces the structural complexity of the material tray switching device, and thus reduces production and maintenance costs.

[0035] Optionally, the first drive mechanism 2 includes a first guide rail 21, a first power device 23, and a first slider 22; a portion of the first guide rail 21 extends into the material transfer space 111; the first slider 22 is slidably disposed on the first guide rail 21; the fixed end of the lifting device 31 is connected to the first slider 22; the first power device 23 is used to drive the lifting device 31 to move along the first guide rail 21 through the first slider 22.

[0036] Specifically, such as Figure 4 As shown, the first guide rail 21 extends along the Y-axis, and the right end of the first guide rail 21 extends into the material transfer space 111; the first slider 22 is slidably disposed on the upper part of the first guide rail 21; the fixed end of the lifting device 31 is connected to the first slider 22; the first power device 23 is a drive motor, which is driven by the first slider 22 through a lead screw. That is to say, the first drive mechanism 2 can be regarded as a linear module here.

[0037] In this optional embodiment, when the first drive mechanism 2 is working, the first power device 23 is activated, which can drive the lifting device 31 to move along the first guide rail 21 through the first slider 22. Due to the presence of the first guide rail 21, the displacement of the lifting device 31 in the Y-axis direction can be limited during the movement of the lifting device 31, thereby reducing the probability of the lifting device 31 deflecting.

[0038] In other embodiments, the first power unit 23 can be a telescopic cylinder, which is connected to the first slider 22 to drive the first slider 22 to move on the first guide rail 21; the first power unit 23 can also be a double winch, with the two winches pulling the first slider 22 back and forth on the first guide rail 21 via ropes.

[0039] Optionally, the first drive mechanism 2 further includes a second guide rail 24 and a second slider 25; the second guide rail 24 is arranged parallel to the first guide rail 21, and a portion of the second guide rail 24 extends into the material transfer space 111; the second slider 25 is slidably disposed on the second guide rail 24; the lifting device 31 is connected to the first slider 22 through the second slider 25, and the fixed end of the lifting device 31 is lower than the first slider 22.

[0040] Specifically, such as Figure 4 As shown, the second guide rail 24 extends along the X-axis direction, and the right end of the second guide rail 24 extends into the material transfer space 111. At this time, the second guide rail 24 is parallel to the first guide rail 21. The second slider 25 is slidably disposed on the second guide rail 24, and the second slider 25 can move along the extension direction of the second guide rail 24 (that is, the X-axis direction). The lifting device 31 is disposed on the second slider 25, and the fixed end of the lifting device 31 is lower than the first slider 22. The first slider 22 and the second slider 25 are connected by the first connecting plate 26. The first connecting plate 26 can be a flat plate or a bent plate. The connection method between the first connecting plate 26 and the first slider 22 and the second slider 25 includes, but is not limited to, snap-fit, plug-in or screw connection. There are no restrictions here, and it depends on the actual needs.

[0041] In this optional embodiment, the lifting device 31 is not directly connected to the first slider 22, but is indirectly connected to the first slider 22 through the second slider 25. This can cause the fixed end of the lifting device 31 to be lower than the first slider 22, thereby reducing the installation height of the lifting device 31 and increasing the stroke range of the lifting device 31.

[0042] Optionally, the mounting frame 11 includes a first support 112 and a second support 113 spaced apart; a material transfer space 111 is formed between the first support 112 and the second support 113; a portion of the first material tray storage unit 12 and a portion of the second material tray storage unit 13 are mounted on the first support 112; and another portion of the first material tray storage unit 12 and another portion of the second material tray storage unit 13 are mounted on the second support 113.

[0043] Specifically, such as Figure 5 As shown, the mounting frame 11 includes a first bracket 112 and a second bracket 113 spaced apart along the Y-axis, forming a material transfer space 111 between the first bracket 112 and the second bracket 113; the first bracket 112 is sequentially mounted with a portion of the first material tray storage unit 12 and a portion of the second material tray storage unit 13 along the X-axis; the second bracket 113 is sequentially mounted with another portion of the first material tray storage unit 12 and another portion of the second material tray storage unit 13 along the X-axis, wherein the two portions of the first material tray storage unit 12 are correspondingly arranged along the Y-axis; the two portions of the second material tray storage unit 13 are correspondingly arranged along the Y-axis.

[0044] In this optional embodiment, during installation, the first bracket 112 and the second bracket 113 are first fixed, and then a portion of the first tray storage unit 12 and a portion of the second tray storage unit 13 are respectively installed on the first bracket 112. The remaining portions of the first tray storage unit 12 and the second tray storage unit 13 are installed on the second bracket 113. Since the mounting frame 11, the first tray storage unit 12, and the second tray storage unit 13 are all separate structures, installation is simpler and installation efficiency can be effectively improved.

[0045] Optionally, both the first tray storage unit 12 and the second tray storage unit 13 include two limiting mechanisms 5 and four corner posts 4; the corner posts 4 are provided with L-shaped slotted structures 41 along their length; two corner posts 4 are vertically arranged on the top of the first support 112 and spaced apart along the first direction; the other two corner posts 4 are vertically arranged on the top of the second support 113 and spaced apart along the first direction; the four corner posts 4 form a first storage area 121 or a second storage area 131, and the slotted structures 41 are located within the first storage area 121 or the second storage area 131; one limiting mechanism 5 is arranged between the two corner posts 4 on the first support 112; another limiting mechanism 5 is arranged between the two corner posts 4 on the second support 113; a portion of the limiting mechanism 5 is used to extend into or out of the first storage area 121 or the second storage area 131.

[0046] It should be understood that the lower end face of the tray 6 is usually provided with a notch so that the limiting mechanism 5 can be inserted from the side end of the tray 6 and supported.

[0047] Specifically, such as Figure 5 As shown, the first tray storage unit 12 and the second tray storage unit 13 have the same structure, both including two limiting mechanisms 5 and four corner posts 4; the corner posts 4 are provided with an L-shaped slotted structure 41 along their length; two corner posts 4 are vertically arranged on the top of the first support 112 and spaced apart along the X-axis; the other two corner posts 4 are vertically arranged on the top of the second support 113 and spaced apart along the X-axis; the four corner posts 4 form a first storage area 121 or a second storage area 131, and the slotted structure 41 is located in the first storage area 121 or the second storage area 131. Within the second storage area 131, one inner wall of the slotted structure 41 is flush with the edge of the first support 112 or the second support 113, and the other inner wall of the slotted structure 41 extends beyond the edge of the first support 112 or the second support 113; a limiting mechanism 5 is disposed between the two corner posts 4 on the first support 112 and connected to the first support 112; another limiting mechanism 5 is disposed between the two corner posts 4 on the second support 113 and connected to the first support 112; a portion of the limiting mechanism 5 is used to extend into or out of the first storage area 121 or the second storage area 131.

[0048] In this optional embodiment, when it is necessary to store the tray 6 containing the contents in the first tray storage unit 12, the lifting device 31 first sends the tray 6 into the first storage area 121 via the pallet 32. At this time, there are two situations:

[0049] In the first scenario, if there is no tray 6 in the first storage area 121 beforehand, after the lifting device 31 transports the tray 6 to a position higher than the limiting mechanism 5 via the pallet 32, the limiting mechanism 5 operates to extend into the first storage area 121. Subsequently, the lifting device 31 retracts, and the bottom of the tray 6 falls onto the part of the limiting mechanism 5 that extends into the first storage area 121. At this time, the tray 6 is supported by the two limiting mechanisms 5 and no longer descends with the lifting device 31, thereby realizing the storage of the tray 6 in the first storage area 121.

[0050] In the second scenario, if the first storage area 121 already contains trays 6, after the lifting device 31 contacts the transported tray 6 with the original bottom tray 6 in the first storage area 121 via the pallet 32, the limiting mechanism 5 operates to exit the second storage area 131. At this time, all trays 6 are supported by the pallet 32 ​​connected to the lifting device 31. Subsequently, the lifting device 31 continues to rise until the pallet 32 ​​is above the limiting mechanism 5. Then, the limiting mechanism 5 operates to extend into the first storage area 121, causing the lifting device 31 to retract. The bottom tray 6 will fall onto the part of the limiting mechanism 5 that extends into the first storage area 121. At this time, the tray 6 is supported by the two limiting mechanisms 5 and no longer descends with the lifting device 31, thus realizing the storage of the tray 6 in the first storage area 121.

[0051] In this optional embodiment, when it is necessary to remove the tray 6 containing the contents from the second tray storage unit 13, the lifting device 31 first moves the pallet 32 ​​into the second storage area 131 until the pallet 32 ​​supports the tray 6 in the second storage area 131. At this time, there are two situations:

[0052] In the first scenario, if the second storage area 131 has multiple empty trays 6 beforehand, after the limiting mechanism 5 operates to exit the second storage area 131, the lifting device 31 retracts. After the displacement is the thickness of one tray 6, the limiting mechanism 5 is activated again. The limiting mechanism 5 extends into the first storage area 121 to support the second-to-last tray 6. Then, the lifting device 31 continues to retract, and the pallet 32 ​​will carry the lowest tray 6 down to the transfer space 111, thereby realizing the removal of the tray 6 from the second storage area 131.

[0053] In the second scenario, if the second storage area 131 has only one empty tray 6 beforehand, after the limiting mechanism 5 operates to exit the second storage area 131, the lifting device 31 retracts, and the pallet 32 ​​will carry the tray 6 down to the transfer space 111, thereby realizing the removal of the tray 6 from the second storage area 131.

[0054] Optionally, the limiting mechanism 5 includes a second power device 51, a third slider 52, and an insert plate 53; the second power device 51 is mounted on the first bracket 112 or the second bracket 113; the insert plate 53 is connected to the third slider 52; the second power device 51 is used to drive the insert plate 53 to move through the third slider 52 to extend beyond the edge of the corresponding first bracket 112 or the edge of the corresponding second bracket 113.

[0055] Specifically, the second power unit 51 is a telescopic cylinder, such as a pneumatic cylinder, hydraulic cylinder, or electric cylinder; there are no restrictions here, and it depends on the actual needs. Figure 5 , 6 As shown, the second power unit 51 is installed on the top of the first bracket 112 or the top of the second bracket 113; the insert plate 53 is connected to the third slider 52, and the connection method between the two includes but is not limited to snap-fit, plug-in or screw connection, which is not limited here and depends on the actual needs.

[0056] In this optional embodiment, when it is necessary to restrict the material tray 6 in the first storage area 121, the two limiting mechanisms 5 of the first material tray storage unit 12 are activated, and the second power device 51 of the two limiting mechanisms 5 is started to drive the insert plates 53 of the two limiting mechanisms 5 to move towards each other along the Y-axis until they are inserted into the notch on the lower end face of the material tray 6, so that the two insert plates 53 can support the material tray 6.

[0057] Similarly, when it is necessary to restrict the material tray 6 in the second storage area 131, the two limiting mechanisms 5 of the second material tray storage unit 13 are activated, and the second power device 51 of the two limiting mechanisms 5 is started to drive the insert plates 53 of the two limiting mechanisms 5 to move towards each other along the Y-axis until they are inserted into the notch on the lower end face of the material tray 6, so that the two insert plates 53 can support the material tray 6.

[0058] In this embodiment, the insert plates 53 of the two limiting mechanisms 5 are located on the same horizontal plane. Thus, after the insert plates 53 support the material tray 6, the material tray 6 is in a horizontal state, thereby reducing the probability of it tipping over.

[0059] Optionally, in the first tray storage unit 12 or the second tray storage unit 13, the two corner posts 4 on the first support 112 and the two corner posts 4 on the second support 113 are arranged in a one-to-one correspondence; and / or, the limiting mechanism 5 on the first support 112 and the limiting mechanism 5 on the second support 113 are arranged in a corresponding manner.

[0060] Specifically, such as Figure 1 , 5 As shown, in the first material tray storage unit 12, the two corner posts 4 on the first bracket 112 and the two corner posts 4 on the second bracket 113 are arranged in a one-to-one correspondence along the Y-axis direction; the limiting mechanism 5 on the first bracket 112 and the limiting mechanism 5 on the second bracket 113 are arranged in a corresponding manner along the Y-axis direction.

[0061] Similarly, in the second material tray storage unit 13, the two corner posts 4 on the first support 112 and the two corner posts 4 on the second support 113 are arranged in a one-to-one correspondence along the Y-axis direction; the limiting mechanism 5 on the first support 112 and the limiting mechanism 5 on the second support 113 are arranged in a corresponding manner along the Y-axis direction.

[0062] Optionally, the lifting device 31 includes a plurality of telescopic cylinders 311 connected in sequence, wherein in two adjacent telescopic cylinders 311, the fixed end of one telescopic cylinder 311 is connected to the telescopic end of the other telescopic cylinder 311.

[0063] Specifically, the number of telescopic cylinders 311 can be two, three, or four, etc., without limitation, depending on actual needs. For example... Figure 3 As shown, there are two telescopic cylinders 311. The fixed end of the first telescopic cylinder 311 is connected to the second slider 25, the telescopic end of the first telescopic cylinder 311 is connected to the fixed end of the second telescopic cylinder 311, and the telescopic end of the second telescopic cylinder 311 is connected to the support plate 32.

[0064] In this optional embodiment, when the height of the pallet 32 ​​needs to be adjusted, multiple telescopic cylinders 311 can be activated sequentially to adjust to a suitable height. Therefore, it is not necessary to customize the telescopic cylinders 311 during production, saving costs.
