The first driver 220 does not constitute a limitation of the present application.
The two transmission assemblies 400 correspond to the two holding assemblies 300 one by one, and each transmission assembly 400 is used for selectively converting the first vertical motion of the vertical moving member 210 into the first transverse reciprocating motion of the transverse moving member 310 in the process that the vertical moving member 210 moves from the first position to the second position, so that one side (close to the outer edge of the vertical moving member 210) of the transverse moving member 310 enters between the two bottommost trays after avoiding the bottommost tray from the lower part of the bottom tray in the stacked plurality of trays; or in the process of moving from the second position to the first position, the second vertical motion of the vertical moving member 210 can be selectively converted into the second transverse reciprocating motion of the transverse moving member 310, so that one side of the transverse moving member 310 is between the two bottommost trays in the stacked trays, and enters the lower part of the bottommost tray after avoiding the bottommost tray.
As shown in FIGS. 1 and 2, the vertical height of the first position is H1, the vertical height of the second position is H2, and H1 is greater than H2.
The process of moving the vertical moving member 210 from the first position to the second position is a part of the process of splitting the tray, and the process of moving the vertical moving member 210 from the second position to the first position is a part of the process of stacking the tray.
In particular, the transmission assembly 400 comprises a transmission rod 402 and a resilient element 401.
The transmission rod 402 is provided with a matching surface 4021 on one side of the vertical direction, a drop (height fluctuation) exists in the transverse height of the matching surface 4021, and the transmission rod 402 is driven by the vertical moving member 210 to move vertically and selectively moves to the motion path of the transverse moving member 310 in the vertical moving process.
The elastic element 401 is connected between the lateral moving member 310 and the frame 320, and is used for generating an elastic force, so that when the transmission rod 402 moves to the motion path of the lateral moving member 310, the lateral moving member 310 and the mating surface 4021 of the transmission rod 402 are always in contact with each other, and thus are in a transmission mating state. The elastic element 401 may be a spring, a rubber pad.
In this embodiment, the transverse height of the engagement surface 4021 is different, and the cross member 310 always abuts against the engagement surface 4021 under the action of the elastic element 401, so that the transverse height difference of the engagement surface 4021 is converted into the transverse movement (the first transverse reciprocating movement and the second transverse reciprocating movement) of the cross member 310, thereby forming the transmission engagement.
In other embodiments, the elastic element 401 may not be used, and other transmission matching structures may be adopted, as shown in embodiment three.
Further, the mating surface 4021 of the transmission rod 402 is located on a side facing away from the vertical moving member 210 and is convex. The elastic force generated by the elastic element 401 makes the lateral moving member 310 always maintain the tendency of moving toward the vertical moving member 210.
In other embodiments, the mating surface 4021 may be located on a side facing the vertical moving member 210, see embodiment two.
Further, the mating surface 4021 includes a first plane 40211, a second plane 40212 and a third plane 40213 connected in sequence, wherein the second plane 40212 is parallel to the vertical direction, and the first plane 40211 and the third plane 40213 extend from the second plane 40212 at both ends of the vertical direction, respectively, and are disposed obliquely to the vertical moving member 210 with respect to the second plane 40212.
As shown in fig. 1 and 5, the length L3 > L1 of the vertical projection of the first plane 40211 in the transverse direction, and L1 is the depth of the transverse moving member 310 inserted under the tray in the transverse direction. The length of the vertical projection of the third plane 40213 in the lateral direction, L2 > L1. The length of the transverse projection of the mating surface 4021 in the vertical direction is L4 < L0, and L0 is the spacing between two adjacent trays.
When the transmission rod 402 is in transmission engagement with the lateral moving member 310, during the movement of the vertical moving member 210 from the first position to the second position, the motion of the lateral moving member 310 is as follows:
the transverse moving member 310 abuts against the third plane 40213 and moves along the transverse back to the vertical moving member 210 under the driving of the third plane 40213, and the process can be regarded as that the transverse moving member 310 withdraws from the projection area of the tray in the vertical direction;
the transverse moving member 310 abuts against the second plane 40212 again, and during the period of abutting against the second plane 40212, the transverse position is unchanged, and in the process, the transverse moving member 310 is completely withdrawn from the vertical projection area of the tray, so that the vertical movement of the tray is avoided;
the horizontal moving member 310 abuts against the first plane 40211 and moves towards the vertical moving member 210 along the horizontal direction under the driving of the first plane 40211, which can be regarded as the process that the horizontal moving member 310 is inserted into the vertical projection area again to support the tray above the horizontal moving member 310.
When the transmission rod 402 is in transmission engagement with the lateral moving member 310, during the movement of the vertical moving member 210 from the second position to the first position, the motion of the lateral moving member 310 is as follows:
the transverse moving member 310 abuts against the first plane 40211 and moves along the transverse back-to-back vertical moving member 210 under the driving of the first plane 40211, and the process can be regarded as that the transverse moving member 310 withdraws from the projection area of the tray in the vertical direction;
the transverse moving member 310 abuts against the second plane 40212 again, and during the period of abutting against the second plane 40212, the transverse position is unchanged, and in the process, the transverse moving member 310 is completely withdrawn from the vertical projection area of the tray, so that the vertical movement of the tray is avoided;
the horizontal moving member 310 abuts against the third plane 40213, and moves towards the vertical moving member 210 along the horizontal direction under the driving of the third plane 40213, which can be regarded as the process that the horizontal moving member 310 is inserted into the projection area of the tray in the vertical direction again to support the tray above the horizontal moving member 310.
In other embodiments, the mating surface 4021 may have other shapes, such as an arc.
In addition, the specific scheme that the transmission rod 402 can selectively move to the motion path of the transverse moving member 310 during the vertical movement is as follows:
the transmission assembly 400 further includes a first connector 403, a second connector 404, and a second driver 407. The first connecting piece 403 is fixedly connected to the vertical moving piece 210, the second connecting piece 404 is movably connected to the first connecting piece 403, the transmission rod 402 is fixed to the second connecting piece 404, and the second driver 407 is configured to drive the first connecting piece 403 and the second connecting piece 404 to move relatively, so that the second connecting piece 404 drives the transmission rod 402 to move, and further the transmission rod 402 can selectively move to the motion path of the horizontal moving piece 310.
The first connecting member 403 has a substantially U-shape, one end of which is connected to the second connecting member 404 and the other end of which is connected to the vertical moving member 210. The U-shaped structure may prevent the first connector 403 from being interfered by the frame 320 during the vertical movement following the vertical moving member 210.
The second driver 407 may be a second oil cylinder or a second air cylinder, and includes a second cylinder body and a second piston rod, where the second cylinder body and the second piston rod are respectively fixed to the first connecting member 403 and the second connecting member 404, and when the second cylinder body and the second piston rod move relatively, the first connecting member 403 and the second connecting member 404 are driven to move relatively. In other embodiments, the second driver 407 may also be a motor screw nut set.
The specific scheme of the movable connection between the second connecting piece 404 and the first connecting piece 403 is as follows:
a slide block 405 is fixed on the side surface of the second connecting piece 404 facing the first connecting piece 403, a guide rail 406 is fixed on the side surface of the first connecting piece 403 facing the second connecting piece 404, and the slide block 405 is clamped on the guide rail 406, is in sliding fit with the guide rail 406, and can slide back and forth in the extending direction of the guide rail 406.
Further, the second connecting member 404 is movably connected to the first connecting member 403 in a direction perpendicular to the horizontal and vertical directions. That is, the guide rail 406 extends in a direction perpendicular to the lateral and vertical directions.
In order to make the driving rod 402 and the lateral moving member 310 smoothly cooperate, the holding assembly 300 further includes a roller 350, the roller 350 is rotatably disposed on the lateral moving member 310 around the axis thereof, and the lateral moving member 310 abuts against the engaging surface 4021 of the driving rod 402 through the roller 350. Roller 350 may be a bearing having an inner race fixedly attached to cross member 310 and an outer race for abutting against mating surface 4021 of drive link 402.
When the lateral moving member 310 directly abuts against the mating surface 4021, a sliding friction force is generated, and when the roller 350 abuts against the mating surface 4021, a rolling friction force is generated, and the rolling friction force is smaller than the sliding friction force, so that the transmission and the transmission of the transmission rod 402 and the lateral moving member 310 can be smoother by the arrangement of the roller 350.
In this embodiment, when the transmission assembly 400 does not transmit, i.e. the lateral moving member 310 is not in transmission engagement with the transmission rod 402, the lateral moving member 310 will be drawn toward the vertical moving member 210 under the elastic force of the elastic element 401. A limiting structure is provided to limit the position of the lateral moving member 310. For this purpose, the holding assembly 300 further includes a guide rod 360, a fixing block 370 and a limiting block 380. The guide rod 360 is fixed on the traverse member 310, the fixing block 370 is fixed on the frame 320 and is slidably connected with the guide rod 360, and the limit block 380 is fixed on the guide rod 360 and is positioned on the side of the fixing block 370, which is opposite to the elastic element 401. When the transmission assembly 400 does not transmit, the limit block 380 abuts against the fixed block 370 to limit the horizontal moving member 310 from moving further in the direction of the elastic force generated by the elastic element 401.
In addition, when the transmission assembly 400 does not transmit, a part of the lateral moving member 310 is positioned in the projection area of the tray in the vertical direction. In the split pallet scenario, the pallet set 20 needs to be lifted above the lateral moving member 310, supported by the lateral moving member 310, and then split into M pallets 10-1 … 10-M. During the lifting process, the lateral moving member 310 blocks the vertical movement of the tray set 20. Similarly, in the stacked tray scenario, the stacked tray group 20 needs to be dropped onto the conveying assembly 100 and conveyed by the conveying assembly 100 to the third station. During the dropping process, the lateral moving member 310 blocks the vertical movement of the tray set 20. To eliminate the obstruction, the lateral moving member 310 needs to be driven to move away from the vertical moving member 210 to avoid the tray set 20. For this purpose, the holding assembly 300 further comprises a third driver 390, and the third driver 390 is used for driving the lateral moving member 310 to move away from the vertical moving member 210. After the third driver 390 drives the lateral moving member 310 to move away from the vertical moving member 210, the driving force is removed to avoid obstructing the lateral movement of the following lateral moving member 310.
Specifically, the third actuator 390 may be a third cylinder or a third cylinder, and includes a third cylinder and a third piston rod, which are fixedly connected to the traverse member 310 and the frame 320, respectively, to actuate the traverse member 310 to move relative to the frame 320. When the third driver 390 is a third cylinder, it drives the horizontal moving member 310 to move back to the vertical moving member 210, i.e. no longer ventilating, so as to achieve the purpose of removing the driving force.
In other embodiments, the third driver 390 can be a motor screw nut set, and the traverse member 310 can be driven to move relative to the frame 320 by a motor.
In order to make the traverse member 310 support the tray above it more stably, the holding assembly 300 further includes a positioning pin 311, and the positioning pin 311 is fixed on the traverse member 310. Correspondingly, each tray 10-1 … 10-M is provided with a positioning hole matched with the positioning pin 311.
In other embodiments, positioning holes may be provided on the cross member 310, or both positioning holes and positioning pins may be provided on the cross member 310.
The working processes of the automatic stacking mechanism for disassembling the tray and stacking the tray of the embodiment are described below.
The process of splitting the tray stack 20 into M trays 10-1 … 10-M specifically includes the following steps:
s101: the transfer assembly 100 is operative to transfer the pallet assembly 20 from the first station to the second station.
In this step, when the tray set 20 is located at the second station, it is located above the vertical moving member 210.
S102: the vertical moving member 210 moves upward to the first position, and at the same time, the third driver 390 drives the lateral moving member 310 to move back to the vertical moving member 210, thereby avoiding the tray group 20.
In this step, when the vertical moving member 210 is located at the first position, the bottom surface of the tray at the lowermost end is higher than the lateral moving member 310.
S103: the vertical moving member 210 moves downward from the first position to the second position, and the selective transmission rod 402 is in transmission engagement with the lateral moving member 310.
One side of the traverse member 310 is located below the bottom tray in the tray set 20, and enters between the bottom two trays after being evacuated.
S104: the vertical moving member 210 moves downward from the second position to the lowest position, and meanwhile, the selective transmission rod 402 is not in transmission fit with the transverse moving member 310.
In this step, the vertical height at the lowest position is H3 (see fig. 1), the upper surface of the vertical moving member 210 is lower than the upper surface of the conveyor belt 114 of the conveying assembly 100, and the vertical moving member 210 can jack up the tray on the conveying assembly 100. The lowest position hereinafter means the same as the lowest position herein.
In this step, the lowermost tray is dropped onto the conveying assembly 100 along with the vertical moving member, and the remaining trays are dropped onto the horizontal moving member 310.
S105: the transfer assembly 100 conveys the tray dropped on the transfer assembly 100 to the third station.
S106: the vertical displacement member 210 is moved upward to the first position while the selective transmission rod 402 is not in transmission engagement with the traverse member 310.
In this step, the reason for selecting not to be in the transmission matching state is that, in the process that the vertical moving member 210 moves upwards to the first position, a tray is placed above the vertical moving member 210, and in this process, the vertical moving member 210 cannot move transversely.
S107: and repeating the steps 103 to 106 until all the trays in the tray group 20 are completely disassembled.
The step 103 to the step S105 are repeated once, namely, a splitting operation is performed.
Taking the splitting tray 10-N as an example, a splitting operation is described, where N is 1, 2, 3 … … M.
When N is 1:
in step S103, in the process that the vertical moving member 210 moves from the first position to the second position, the transmission assembly 400 is controlled to convert the first vertical motion of the vertical moving member 210 into the first transverse reciprocating motion of the transverse moving member 310, and one side of the transverse moving member 310 enters between the pallets 10-1 and 10-2 after avoiding the pallet 10-1 from the lower side of the pallet 10-1. During the movement of the vertical moving member 210 from the second position to the lowermost position, the stacked trays 10-2, 10-3 … 10-M fall on the lateral moving member 310, being supported by the lateral moving member 310.
In step S104, the tray 10-1 moves downward along with the vertical moving member 210 until it falls on the conveying assembly 100.
In step S105, the conveying assembly 100 conveys the tray 10-1 to the third station.
In step S106, the stacked trays 10-2 and 10-3 … 10-M are pushed away from the lateral moving member 310 during the vertical movement of the vertical moving member 210.
When N is 2, 3 … … M-1:
in step S103, in the process that the vertical moving member 210 moves from the first position to the second position, the transmission assembly 400 is controlled to convert the first vertical motion of the vertical moving member 210 into the first transverse reciprocating motion of the transverse moving member 310, and one side of the transverse moving member 310 enters between the pallets 10-N and 10- (N +1) after avoiding the pallet 10-N from the lower side of the pallet 10-N. In the process that the vertical moving member 210 moves from the second position to the lowermost position, the stacked trays 10- (N +1), 10- (N +2) … 10-M are dropped on the lateral moving member 310, being supported by the lateral moving member 310.
In step S104, the tray 10-N moves downward along with the vertical moving member 210 until it falls on the conveying assembly 100.
In step S105, the transport assembly 100 transports the tray 10-N to a third station.
In step S106, the stacked trays 10- (N +1), 10- (N +2) … 10-M are pushed away from the lateral moving member 310 during the vertical movement of the vertical moving member 210.
When N is M:
in step S103, in the process that the vertical moving member 210 moves from the first position to the second position, the transmission assembly 400 is controlled to convert the first vertical motion of the vertical moving member 210 into the first transverse reciprocating motion of the transverse moving member 310, and one side of the transverse moving member 310 enters the upper side of the tray 10-M from the lower side of the tray 10-M and after avoiding the tray 10-M. During the process that the vertical moving member 210 moves from the second position to the lowest position, there is no tray above the lateral moving member 310.
In step S104, the tray 10-M moves downward along with the vertical moving member 210 until it is dropped onto the transferring assembly 100.
In step S105, the transfer assembly 100 conveys the tray 10-M to the third station.
In step S106, there is no load above the vertical moving member 210 during the vertical movement.
The process of stacking the M trays 10-1, 10-2, 10-3 … 10-M together to form the tray stack 20 specifically includes the steps of:
s201: the transfer assembly 100 transports the trays from the first station to the second station.
In this step, the tray is located above the vertical moving member 210 when located at the second station.
S202: the vertical moving member 210 moves upward from the lowest position to the second position, and the selective transmission rod 402 is not in transmission engagement with the lateral moving member 310.
In this step, the tray is jacked up by the vertical moving member 210 and is driven to rise by the vertical moving member 210.
S203: the vertical moving member 210 moves upward from the second position to the first position, and at the same time, the selective transmission rod 402 is in transmission engagement with the lateral moving member 310.
In this step, one side of the traverse member 310 is moved from between the two lowermost trays of the stacked plurality of trays to the position below the lowermost tray after avoiding the lowermost tray.
S204: the vertical moving member 210 moves downward to the lowest position, and at the same time, the transmission rod 402 is selected not to be in transmission engagement with the lateral moving member 310.
In this step, the tray is placed on top of the traverse 310.
S205: steps S201-S204 are repeated until M trays 10-1, 10-2, 10-3 … 10-M are stacked to form the tray stack 20.
The stacking operation is performed every time steps S201 to S204 are repeated.
One stacking operation will be described by taking the stacking tray 10-N as an example, where N is 1, 2, and 3 … … M.
When N is 1:
in step S201, the conveying assembly 100 conveys the tray 10-1 from the first station to the second station.
In step S202, the vertical moving member 210 pushes the tray 10-1 away from the conveying assembly 100 and lifts the tray 10-1 up during the vertical movement.
In step S203, one side of the traverse member 310 enters the lower side of the pallet 10-1 after avoiding the pallet 10-1 from the upper side of the pallet 10-1.
In step S204, the tray 10-1 is placed on the traverse member 310 and supported by the traverse member 310.
When N is 2, 3 … … M:
in step S201, the conveying assembly 100 conveys the tray 10-N from the first station to the second station.
In step S202, the vertical moving member 210 pushes the tray 10-N away from the transmission assembly 100 and lifts the tray 10-N up during the vertical movement.
In step S203, one side of the traverse member 310 enters the lower side of the pallet 10-N after avoiding the pallet 10-N from the middle of the pallets 10- (N-1) and 10-N.
In step S204, the stacked pallets 10-1, 10-2 … 10-N are dropped onto the traverse 310 and supported by the traverse 310.
S206: the vertical displacement member 210 is moved upward to the first position while the selective transmission rod 402 is not in transmission engagement with the traverse member 310.
In this step, the vertical moving member 210 moves upward to the first position, and the tray set 20 is lifted up, so that the tray set 20 is separated from the lateral moving member 310.
S207: the vertical moving member 210 is driven to move downwards to the lowest position, and at the same time, the third driver 390 drives the horizontal moving member 310 to move back to the vertical moving member 210, thereby avoiding the tray group 20.
In this step, the tray set 20 is dropped onto the transfer unit 100.
S208: the transfer assembly 100 transports the pallet set 20 to the third station.

Meanwhile, the vertical movement of the vertical moving member 210 is converted into the transverse movement of the transverse moving member 310 through the transmission assembly 400, so that the transverse moving member 310 is associated with the vertical moving member 210 at the transverse position, one side of the transverse moving member 310 can be ensured to be accurately inserted above or below the bottommost tray, and the tray is prevented from being damaged by insertion.

Specifically, the automatic folding member mechanism 2000 includes a vertical moving member (not shown), a lateral moving member 2200, a driving rod 2100, and an elastic member (not shown). The engagement surface 2110 of the drive rod 2100 is located on the side facing the vertical moving member and is recessed. The elastic force generated by the elastic element makes the lateral moving member 2200 always keep the tendency of moving back to the vertical moving member (moving to the left in fig. 8).
Further, the fitting surface 2110 includes a first plane 2111, a second plane 2112, and a third plane 2113 connected in this order, in which the second plane 2112 is parallel to the vertical direction, and the first plane 2111 and the third plane 2113 extend from the second plane 2111 at both ends in the vertical direction, respectively, and are disposed obliquely to the vertical moving member direction with respect to the second plane 2112.
When the transmission rod 2100 and the lateral moving member 2200 are in transmission fit, during the movement of the vertical moving member from the first position to the second position, the movement of the lateral moving member 2200 is as follows:
the transverse moving member 2200 abuts against the third plane 2113, and moves along the transverse back-to-back vertical moving member 210 under the driving of the third plane 2113; the transversal moving member 2200 abuts against the second plane 2112 again, and is not changed in the transversal direction during the abutment against the second plane 2112; the horizontal moving member 2200 abuts against the first plane 2111, and moves towards the vertical moving member along the horizontal direction under the driving of the first plane 2111.
When the transmission rod 2100 and the lateral moving member 2200 are in transmission fit, during the movement of the vertical moving member from the second position to the first position, the movement of the lateral moving member 2200 is as follows:
the transverse moving member 2200 abuts against the first plane 2111 and moves along the transverse back-to-back vertical moving member under the driving of the first plane 2111; the transversal moving member 2200 abuts against the second plane 2112 again, and is not changed in the transversal direction during the abutment against the second plane 2112; the horizontal moving member 2200 abuts against the third plane 2113, and moves towards the vertical moving member along the horizontal direction under the driving of the third plane 2113.
From the above analysis, the transmission assembly of the second embodiment can also achieve the effect of the transmission assembly of the first embodiment.
The present embodiment only describes the differences from the first embodiment, and the rest of the embodiments refer to the first embodiment
In this embodiment, in the process of splitting or stacking the trays, one side of the lateral moving member 2200 switches positions on two sides of the lowermost tray, and after the completion of a single splitting operation or stacking operation, the stacked trays above the lateral moving member 2200 are supported, so that the trays are prevented from being damaged.
Example three:
as shown in fig. 8, the present application provides an automatic stack-up mechanism 3000 that provides an alternative to the drive assembly of the first embodiment.
Specifically, automatic stack-up mechanism 3000 includes a vertically oriented moving member (not shown), a lateral moving member 3200 and a drive link 3100. The lateral moving member 3200 is provided with a roller 3300. Drive link 3100 is provided with opposing mating surfaces 3110, 3120, wherein mating surface 3110 is concave and mating surface 3120 is convex. In the driving engagement of lateral moving member 3200 with drive link 3100, roller 3300 is sandwiched between engagement surfaces 3110, 3120 and rolls relative to drive link 3100.
As can be seen from the analysis of the first embodiment and the second embodiment, the transmission assembly of the third embodiment can also achieve the effect of the transmission assembly of the first embodiment.
In addition, the transmission assembly in the third embodiment may not use the elastic element.
The present embodiment only describes the differences from the first embodiment, and the rest of the embodiments refer to the first embodiment.

S1103: the vertical moving member 210 is moved from the second position to the lowest position, so that the vertical moving member 210 lifts the tray 10-1 to move downwards until the tray falls on the transmission assembly 100, and the trays 10-2 and 10-3 … 10-M fall on the lateral moving member 310.
In this step, since one side of the traverse member 310 is located between the tray 10-1 and the tray 10-2, in the process that the tray group 20 moves downward following the vertical moving member 210, the trays 10-2 and 10-3 … 10-M are first placed on the traverse member 310, then the tray 10-1 is separated from the trays 10-2 and 10-3 … 10-M, and the tray 10-1 moves downward following the vertical moving member 210 until it is placed on the conveying assembly 100.
The above steps S1101 to S1103 complete one splitting operation, and the repeating steps S1101 to S1103 can complete multiple splitting operations.
The automated stacking method comprises:
s1201: the vertical moving member 210 is moved from the lowest position to the second position, so that the vertical moving member 210 lifts the tray 10-1 to be stacked up from the conveying assembly 100 and lifts the tray 10-1 to move upward, thereby stacking the tray 10-1 with the trays 10-2, 10-3 … 10-M dropped on the lateral moving member 310 to form the tray group 20.
S1202: the vertical moving member 210 is moved from the second position to the first position, and the second vertical movement of the vertical moving member 210 is selectively converted into the second transverse reciprocating movement of the transverse moving member 310, so that one side of the transverse moving member 310 gets out of the space between the two bottommost pallets 10-1 and the pallets 10-2 in the pallet group 20 and enters the space below the pallets 10-1 after getting out of the space between the two bottommost pallets 10-1.
S1203: the vertical moving member 210 is moved from the first position to the lowest position, so that the vertical moving member 210 lifts the tray group 20 to move downwards, and the tray group 20 is dropped on the lateral moving member 310.
The above steps S1201 to S1203 complete one stacking operation, and repeating the steps S1201 to S1203 can complete multiple stacking operations.
In this embodiment, in the process of splitting or stacking the trays, one side of the lateral moving member 310 switches positions on two sides of the lowermost tray, and after the completion of a single splitting operation or stacking operation, the tray above the lateral moving member 310 is supported by the lateral moving member, so that the tray is prevented from being damaged.
