Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and particularly to a stacking mechanism and a stacking device. Background Art

[0002] In some production workshops, stacking operations are required, such as stacking objects like trays and frames together.

[0003] Taking the industrial cultivation of Boletus aereus as an example, after the bottle-digging process, empty bottle frames (i.e., empty bottles packed in frames) are sent to the bottling room for re-bottling. Currently, the empty bottle frames are stacked together manually and then sent to the bottling operation location together. However, manual bottling is time-consuming and laborious, and the operation efficiency is low. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a stacking mechanism and a stacking device, which can save manpower and improve the stacking operation efficiency.

[0005] To achieve the above object, the present invention mainly provides the following technical solutions:

[0006] On the one hand, an embodiment of the present invention provides a stacking mechanism, including: a lifting mechanism and a supporting mechanism;

[0007] The lifting mechanism is used to drive the supporting mechanism to lift and lower;

[0008] The supporting mechanism is used to support the objects to be stacked;

[0009] When the lifting mechanism drives the supporting mechanism to rise from a first preset height to a second preset height, the supporting mechanism is in a supporting state; the second preset height is a height sufficient to place the objects to be stacked below the supporting mechanism;

[0010] When the lifting mechanism drives the supporting mechanism to descend to a third preset height, the supporting mechanism is in a released state, and until the supporting mechanism descends to the first preset height, the supporting mechanism is in a supporting state.

[0011] Specifically, the supporting mechanism includes a supporting member and a mechanism component, and the stacking mechanism further includes a triggering component. The supporting member is connected to the mechanism component. The triggering component is used to trigger the mechanism component when the supporting mechanism descends to the third preset height, and the mechanism component makes the supporting member in a released state.

[0012] Specifically, the mechanism component includes a mechanism part and a mechanism reset part. The triggering component is a guide rail fixedly arranged along the lifting direction. The mechanism part is rotatably connected to the holding part, and the mechanism reset part is connected to the mechanism part. When the holding part is at the first preset height, the mechanism part is in a state of being disengaged from the triggering component, and the holding part is in a holding state. When the holding part rises, the mechanism part contacts the triggering component, and the mechanism part rotates to a position where the holding part is kept in the holding state. When the holding part rises to the second preset height, the mechanism part disengages from the triggering component, and the mechanism reset part drives the mechanism part to return to its original position before rotation. When the holding part descends to the third preset height, the mechanism part contacts the triggering component. Under the action of the outward pushing force of the triggering component on it, the mechanism part moves outward and drives the holding part to move outward, so that the holding part is in a released state until the holding part descends to the first preset height and the mechanism part disengages from the triggering component.

[0013] Specifically, the holding mechanism further includes a holding reset component, which is connected to the holding part. When the holding mechanism descends to the first preset height, the triggering component disconnects the trigger with the mechanism component, and the holding reset component drives the holding part to return to the holding state.

[0014] Specifically, the mechanism reset part is an elastic component. One end of the mechanism reset part is connected to the holding part, and the other end of the mechanism reset part is connected to the mechanism part.

[0015] A limiting structure is arranged on the mechanism part to limit the rotation of the mechanism part between a first position and a second position. The initial position of the mechanism part is the first position. When the holding part rises and starts to contact the triggering component, the triggering component presses the mechanism part to make the mechanism part rotate in the direction of the second position against the elastic force of the mechanism reset part. During the process of the mechanism part contacting the triggering component and rising, the rotation angle of the mechanism part is less than or equal to the angle from the first position to the second position. When the holding part rises to disengage from the triggering component and the mechanism reset part drives the mechanism part to reset, the limiting structure restricts the mechanism part from rotating back to the first position.

[0016] When the holding part descends and starts to contact the triggering component, the triggering component pushes against the mechanism part. The mechanism part is in the first position under the restriction of the limiting structure until the mechanism part descends to disengage from the triggering component, and the limiting structure restricts the mechanism part to always be in the first position.

[0017] Specifically, inclined surfaces that gradually narrow towards the ends are respectively provided at both ends of the triggering member;

[0018] And / or, the stacking mechanism further includes a telescopic guide rail, the holding member is slidably connected to the telescopic guide rail, and the telescopic guide rail is used to guide the reciprocating movement trajectory of the holding member moving outward and resetting.

[0019] Specifically, the lifting mechanism includes a driving mechanism and a crank-link mechanism, the driving mechanism is connected to the crank-link mechanism, the crank-link mechanism is connected to the holding mechanism, and the driving mechanism is used to drive the crank-link mechanism to move so as to drive the holding mechanism to lift;

[0020] And / or, the stacking mechanism further includes a first monitoring component for monitoring the stacking layers and / or stacking height of the stacked objects. When the first monitoring component monitors that the stacking height is not lower than a fourth preset height, an operation completion signal is issued; wherein, the fourth preset height is higher than the second preset height;

[0021] And / or, the stacking mechanism further includes a lifting guide rail, the holding mechanism is slidably connected to the lifting guide rail, and the lifting guide rail is used to guide the lifting trajectory of the holding mechanism.

[0022] On the other hand, an embodiment of the present invention provides a (herein introduce all the content of another independent claim.)

[0023] A stacking device provided by an embodiment of the present invention includes: a stacking workbench and the above-mentioned stacking mechanism;

[0024] The stacking workbench includes a stacking operation area, and the holding mechanism of the stacking mechanism is located above the stacking operation area.

[0025] Specifically, the stacking workbench includes a conveying part, the conveying part is used to convey the stacked objects to be stacked to the stacking operation area, and the conveying part is also used to convey the stacked objects after stacking out of the stacking operation area;

[0026] When the stacking mechanism includes a first monitoring component for monitoring the stacking layers and / or stacking height of the stacked objects, the first monitoring component is connected to the conveying part. When the first monitoring component issues the operation completion signal, the conveying part receives the operation completion signal and starts conveying.

[0027] Furthermore, the above-mentioned stacking device further includes: a second monitoring component for issuing a stacking signal when it monitors that the stacked object to be stacked is within the stacking operation area;

[0028] When the stacking workbench includes a conveying part, the second monitoring component is connected to the conveying part. When the second monitoring component emits the stacking signal, the conveying part receives the stacking signal and stops conveying; and / or,

[0029] When the stacking workbench includes a conveying part, a positioner is arranged at the stacking operation area. The positioner is connected to the second monitoring component. When the second monitoring component emits the stacking signal, the positioner moves to block the movement of the stacked objects within the stacking operation area.

[0030] A stacking mechanism and a stacking device provided by an embodiment of the present invention. The stacking mechanism is arranged above the stacking operation area of the stacking workbench. During the stacking operation, the lifting mechanism drives the holding mechanism to lift and lower, so that the holding mechanism drives the stacked objects to lift and lower. During the lifting and lowering process, the holding mechanism changes between the holding state and the releasing state at a preset position. First, the holding mechanism raises a stacked object to a sufficient height so that another stacked object can be placed under it. Then, the holding mechanism drives the raised stacked object to descend onto the stacked object below. Then, the holding mechanism raises the stacked objects that have been stacked together to a sufficient height again, so that another stacked object can be placed below. Then, it descends until three stacked objects are stacked together. After that, the holding mechanism raises the three stacked objects together again, and so on, to complete the stacking operation. Compared with the prior art in which manual stacking operation is adopted, the stacking mechanism of the embodiment of the present invention does not require manual stacking, thus saving manpower, improving the stacking operation efficiency, and being able to avoid situations such as stacking deviation and tipping that are prone to occur in manual stacking.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] As Figure 1 shown, an embodiment of the present invention provides a stacking mechanism, including: a lifting mechanism 1 and a holding mechanism 2; the lifting mechanism 1 is used to drive the holding mechanism 2 to lift and lower; the holding mechanism 2 is used to hold the stacking objects to be stacked.

[0044] The stacking mechanism is used to be arranged at the stacking workbench 3. The stacking operation area of the stacking workbench 3 is located below the stacking mechanism. The stacking workbench 3 may include a conveying part. For example, the stacking workbench 3 can be designed in a way of conveyor belt conveying, and is used to convey the stacking objects to be stacked to the stacking operation area one by one, and stack these stacking objects together through the stacking mechanism. Or, the stacking workbench 3 can also be a stationary platform, and the stacking objects to be stacked can be transported to the stacking operation area of the stacking workbench 3 one by one through a conveying robot, etc., and stack these stacking objects together through the stacking mechanism. This will not be elaborated here for the time being.

[0045] Combined with Figures 2 to 5, during stacking operations, a first stack 41 is placed on the stacking operation area, and the holding mechanism 2 is at a first preset height 51. The first preset height 51 is the height position at which the holding mechanism 2 holds or is ready to hold the first stack 41 placed on the stacking operation area. The lifting mechanism 1 drives the holding mechanism 2 to rise from the first preset height 51 to a second preset height 52. During this process, the holding mechanism 2 is in a holding state, that is, it holds the first stack 41 and rises. The second preset height 52 is a height sufficient to place the stack to be stacked below the holding mechanism 2. That is to say, after the holding mechanism 2 rises to the second preset height 52, a second stack 42 is placed on the stacking operation area. There is enough space between the second preset height 52 and the stacking operation area to place the second stack 42. Then the lifting mechanism 1 drives the holding mechanism 2 to descend. The holding mechanism 2 descends with the first stack 41. When the holding mechanism 2 descends to a third preset height 53, the holding mechanism 2 is in a released state. The third preset height 53 is equal to or lower than the height of the holding mechanism 2 when the first stack 41 descends and is stacked on the second stack 42, so that the first stack 41 can be stably stacked on the first stack 41; if the third preset height 53 is relatively high, the holding mechanism 2 releases the second stack 42. At this time, if the second stack 42 does not contact the first stack 41, the second stack 42 will freely fall onto the first stack 41, and it is easy to occur skewing or damage, etc. The holding mechanism 2 is in a released state during the descending process. When the holding mechanism 2 descends to the first preset height 51, the holding mechanism 2 returns to the holding state. Then the lifting mechanism 1 drives the holding mechanism 2 to rise. The holding mechanism 2 holds the first stack 41 and the second stack 42 located on the first stack 41 and rises together. After reaching the second preset height 52, a third stack is placed on the stacking operation area, and the foregoing working process is repeated, thus completing the stacking operation.

[0046] Among them, the lifting mechanism 1 can adopt an electric cylinder, a cylinder, a crank connecting rod, a threaded screw, a rack and pinion, a worm and worm gear mechanism, etc., which are not limited herein. The holding mechanism 2 can adopt a jaw, a clamping plate, a supporting plate, etc. for holding, which are not limited herein. The holding state and the released state of the holding mechanism 2 can be controlled to change its state through an electric control or a mechanical structure, which is not limited herein for the time being.

[0047] The working principle of the stacking mechanism will be specifically described below with reference to the embodiments of the present invention. Taking the industrial cultivation of Boletus aereus as an example, after the bottle-digging process, the empty bottle frames (i.e., empty bottles are placed in the frames) need to be stacked together and then sent to the bottle-filling operation area. First, place the first empty bottle frame in the stacking operation area. The holding mechanism 2 is located at the first preset height 51 to hold the first empty bottle frame. The lifting mechanism 1 drives the holding mechanism 2 to rise, so as to drive the first empty bottle frame to rise until it reaches the second preset height 52. Then place the second empty bottle frame in the stacking operation area. Then the lifting mechanism 1 drives the holding mechanism 2 to descend, so as to drive the first empty bottle frame to descend. When the holding mechanism 2 descends to the third preset height 53, the holding mechanism 2 releases the first empty bottle frame. The first empty bottle frame and the second empty bottle frame are stacked together. The holding mechanism 2 continues to descend. When it descends to the first preset height 51, it resumes the holding state and holds the second empty bottle frame. Then the lifting mechanism 1 drives the holding mechanism 2 to rise, so as to drive the second empty bottle frame and the first empty bottle frame stacked on the second empty bottle frame to rise together until it reaches the second preset height 52. Place the third empty bottle frame in the stacking operation area. After that, repeat the above-described working process. In this way, multiple empty bottle frames are stacked together.

[0048] The stacking mechanism provided by the embodiments of the present invention drives the holding mechanism 2 to lift through the lifting mechanism 1, so that the holding mechanism 2 drives the stacked objects to lift. During the lifting process, the holding mechanism 2 changes between the holding state and the releasing state at the preset position. First, the holding mechanism 2 raises a stacked object to a sufficient height so that another stacked object can be placed under it. Then the holding mechanism 2 drives the raised stacked object to descend onto the stacked object placed below. Then the holding mechanism 2 raises the stacked objects stacked together to a sufficient height again, so that another stacked object can be placed below. Then it descends until three stacked objects are stacked together. After that, the holding mechanism 2 raises the three stacked objects together again. Repeat this process to complete the stacking operation. Compared with the manual stacking operation method in the prior art, the stacking mechanism of the embodiments of the present invention does not require manual stacking, thus saving manpower, improving the stacking operation efficiency, and being able to avoid situations such as stacking deviation and tipping that are easily caused by manual stacking.

[0049] Specifically, refer to Figure 4, the holding mechanism 2 includes a holding member 21 and a mechanism member 22, and the stacking mechanism further includes a triggering member 6. The holding member 21 is connected to the mechanism member 22. The triggering member 6 is used to trigger the mechanism member 22 when the holding mechanism 2 descends to the third preset height 53, and the mechanism member 22 makes the holding member 21 in a released state. Among them, the holding member 21 can be designed as a holding plate or a clamping jaw, a clamping plate, etc., and cooperate with the triggering member 6 to hold or release at a preset height, and can adopt an electric triggering or a mechanical triggering method, which is not limited here for the time being. For example, the triggering member 6 can include a monitor, and the mechanism member 22 can include a controller. The controller is connected to the holding member 21. When the monitor monitors that the holding member 21 descends and reaches the third preset height 53, the monitor sends a corresponding signal to the controller to make the controller control the holding member 21 to release. However, this electric triggering method is more costly and more troublesome to design than the mechanical triggering method. Therefore, a mechanical triggering method can be adopted, and the specific structure will be described in detail in the following embodiments and will not be elaborated here for the time being.

[0050] Specifically, refer to Figure 5 , the holding mechanism 2 further includes a holding reset member 23. The holding reset member 23 is connected to the holding member 21. When the holding mechanism 2 descends to the first preset height 51, the triggering member 6 disconnects from the mechanism member 22, and the holding reset member 23 drives the holding member 21 to return to the holding state. Among them, the holding reset member 23 can be an elastic member or a controller, etc., and can restore the holding member 21 to the original holding position by elastic force, or can also control the holding member 21 to return to the original holding position through the controller.

[0051] Specifically, in combination with Figures 6 to 9, the mechanism component 22 includes a mechanism part 221 and a mechanism reset part 222. The trigger component 6 is a guide rail fixedly arranged along the lifting direction. The mechanism part 221 is rotatably connected to the holding part 21, and the mechanism reset part 222 is connected to the mechanism part 221. When the holding part 21 is at the first preset height 51, the mechanism part 221 is in a state of disengaging from the trigger component 6, and the holding part 21 is in a holding state. When the holding part 21 rises, the mechanism part 221 contacts the trigger component 6, and the mechanism part 221 rotates to a position where the holding part 21 is kept in the holding state. When the holding part 21 rises to the second preset height 52, the mechanism part 221 disengages from the trigger component 6, and the mechanism reset part 222 drives the mechanism part 221 to return to its original position before rotation. When the holding part 21 descends to the third preset height 53, the mechanism part 221 contacts the trigger component 6. Under the action of the outward pushing force of the trigger component 6 on it, the mechanism part 221 moves outward and drives the holding part 21 to move outward, so that the holding part 21 is in a released state until the holding part 21 descends to the first preset height 51 and the mechanism part 221 disengages from the trigger component 6. Among them, the rotation of the mechanism part 221 can be controlled electrically or rotated under the action of the trigger component 6. For example, the mechanism part 221 is connected to a controller, and a monitor is arranged on the trigger component 6. When it is detected that the holding part 21 rises, a corresponding signal is sent to the controller, and the controller controls the rotation of the mechanism part 221. Or the following all-mechanical trigger implementation method can also be adopted:

[0052] The mechanism reset part 222 is an elastic component. One end of the mechanism reset part 222 is connected to the holding part 21, and the other end of the mechanism reset part 222 is connected to the mechanism part 221. Among them, the mechanism reset part 222 is an elastic component, and a spring or the like can be adopted.

[0053] See Figures 6 to 9 , a limiting structure 2211 is arranged on the mechanism part 221 to limit the rotation of the mechanism part 221 between the first position and the second position. The initial position of the mechanism part 221 is the first position, that is, when the mechanism part 221 is at the first position, the holding part 21 is in the holding state. When the holding part 21 rises and starts to contact the trigger component 6, the trigger component 6 presses the mechanism part 221 to make the mechanism part 221 rotate in the direction of the second position against the elastic force of the mechanism reset part 222. During the process of the mechanism part 221 contacting the trigger component 6 and rising, the rotation angle of the mechanism part 221 is less than or equal to the angle from the first position to the second position. When the holding part 21 rises to the point where the mechanism part 221 disengages from the trigger component 6 and the mechanism reset part 222 drives the mechanism part 221 to reset, the limiting structure restricts the mechanism part 221 from rotating back to the first position. Among them, the limiting structure can be designed as an arc-shaped hole. A limiting pin is fixedly arranged on the holding part 21, and the limiting pin passes through the arc-shaped hole. When the mechanism part 221 rotates, the limiting pin in the arc-shaped hole enables the mechanism part 221 to rotate between the first position and the second position without exceeding this range.

[0054] When the supporting member 21 descends and starts to contact the triggering member 6, the triggering member 6 presses against the mechanism member 221. The mechanism member 221 is in the first position under the restriction of the limiting structure until the mechanism member 221 descends to disengage from the triggering member 6, and the limiting structure restricts the mechanism member 221 to always be in the first position.

[0055] Wherein, when the supporting member 21 ascends, the triggering member 6 has a downward acting force on it, causing the mechanism member 221 to rotate. The limiting structure restricts the rotation angle from being too large. When the mechanism member 221 rotates to the second position or has not rotated to the second position yet, the rotation stops. Due to the rotation of the mechanism member 221, the supporting member 21 is not affected by the triggering member 6 and ascends while maintaining the supporting state. When it ascends to the point where the mechanism member 221 disengages from the triggering member 6, the mechanism reset member 222 drives the mechanism member 221 to rotate to the first position. When the supporting member 21 descends, the triggering member 6 has an upward acting force on it. Under the restriction of the limiting structure, the mechanism member 221 cannot rotate. The mechanism member 221 always remains in the first position. The triggering member 6 also has an outward acting force on the mechanism member 221. The mechanism member 221 cannot rotate and is pushed outward. The mechanism member 221 drives the supporting member 21 to move outward, so that the supporting member 21 descends in a released state. Until it descends to the first preset position, the mechanism member 221 disengages from the triggering member 6, and the supporting member 21 returns to the position of the supporting state under the action of the supporting reset member 23.

[0056] Specifically, referring to Figure 6 , both ends of the triggering member 6 are respectively provided with inclined surfaces 61 that gradually narrow towards the ends; the inclined surfaces 61 enable the mechanism member 221 to be stressed gradually during contact with the triggering member 6, so that the stress on it gradually increases, so as to prevent the triggering member 6 or the mechanism member 221 from being damaged.

[0057] Furthermore, referring to Figure 10 , the stacking mechanism further includes a telescopic guide rail 7. The supporting member 21 is slidably connected to the telescopic guide rail 7. The telescopic guide rail 7 is used to guide the reciprocating movement trajectory of the supporting member 21 moving outward and resetting. Among them, the telescopic guide rail 7 is used to guide the movement of the supporting member 21 extending inward or retracting outward. That is, when the supporting member 21 moves inward to the supporting state or moves outward to the released state, the telescopic guide rail 7 ensures that the supporting member 21 moves horizontally and does not deviate from the position it should be in. The telescopic guide rail 7 can adopt a linear bearing, and the supporting member 21 is slidably connected to the linear bearing through bearing steel.

[0058] Specifically, as Figure 1As shown in the figure, the lifting mechanism 1 includes a driving mechanism 11 and a crank and connecting rod mechanism 12. The driving mechanism 11 is connected to the crank and connecting rod mechanism 12, and the crank and connecting rod mechanism 12 is connected to the holding mechanism 2. The driving mechanism 11 is used to drive the crank and connecting rod mechanism 12 to move so as to drive the holding mechanism 2 to lift. Among them, the driving mechanism 11 can adopt a motor, which is connected to the crank and connecting rod mechanism 12 to drive the crank to rotate, thereby driving the end of the connecting rod connected to the holding mechanism 2 to move up and down. This design method is relatively simple and easy to implement.

[0059] Furthermore, the stacking mechanism further includes a first monitoring component 8, which is used to monitor the stacking layers and / or stacking height of the stacked objects. When the first monitoring component 8 monitors that the stacking height is not lower than the fourth preset height 54, an operation completion signal is sent out; among them, the fourth preset height is higher than the second preset height 52. Among them, the first monitoring component 8 can be a camera or a sensor, etc. When it monitors that the stacked objects reach the fourth preset height 54, an operation completion signal is sent out, and this signal can be sent to the conveying part that conveys the stacked objects to the stacking operation area, or can be sent to the operation console, etc., so that the conveying part conveys the stacked stacked objects away, or the operation console performs corresponding control operations such as stopping stacking and sending away the stacked objects.

[0060] Furthermore, the stacking mechanism further includes a lifting guide rail 9. The holding mechanism 2 is slidably connected to the lifting guide rail 9, and the lifting guide rail 9 is used to guide the lifting trajectory of the holding mechanism 2. Among them, the lifting guide rail 9 can adopt bearing steel, and the holding mechanism 2 can be slidably connected to the bearing steel through a linear bearing.

[0061] The stacking mechanism provided by the embodiment of the present invention drives the holding mechanism 2 to lift through the lifting mechanism 1, so that the holding mechanism 2 drives the stacked objects to lift. During the lifting process, the holding mechanism 2 changes between the holding state and the releasing state at a preset position to complete the stacking operation. Compared with the manual stacking operation method in the prior art, the stacking mechanism of the embodiment of the present invention does not require manual stacking, thereby saving manpower, improving the stacking operation efficiency, and being able to avoid situations such as stacking deviation and tipping that are easily caused by manual stacking.

[0062] As Figure 1 As shown in the figure, the embodiment of the present invention provides a stacking device, including: a stacking workbench 3 and the above-mentioned stacking mechanism; the stacking workbench 3 includes a stacking operation area, and the holding mechanism 2 of the stacking mechanism is located above the stacking operation area.

[0063] Among them, the structure and working principle of the stacking mechanism are the same as those in the foregoing embodiments, and will not be elaborated here.

[0064] The stacking device provided by the embodiment of the present invention has a stacking mechanism disposed above the stacking operation area of the stacking workbench 3. During the stacking operation, the lifting mechanism 1 drives the holding mechanism 2 to lift, so that the holding mechanism 2 drives the stacked objects to lift. During the lifting process, the holding mechanism 2 changes between the holding state and the releasing state at a preset position. First, the holding mechanism 2 raises a stacked object to a sufficient height so that another stacked object can be placed below it. Then, the holding mechanism 2 drives the raised stacked object to descend onto the stacked object placed below. Then, the holding mechanism 2 raises the stacked objects stacked together to a sufficient height again, so that another stacked object can be placed below. Then, it descends until three stacked objects are stacked together. After that, the holding mechanism 2 raises the three stacked objects together, and so on, to complete the stacking operation. Compared with the manual stacking operation method in the prior art, the stacking mechanism of the embodiment of the present invention does not require manual stacking, thus saving manpower, improving the stacking operation efficiency, and being able to avoid situations such as stacking deviation and tipping that are likely to occur in manual stacking.

[0065] Specifically, referring to Figure 11 , the stacking workbench 3 includes a conveying part 31. The conveying part 31 is used to convey the stacked objects to be stacked to the stacking operation area 32, and the conveying part 31 is also used to convey the stacked objects that have been stacked out of the stacking operation area 32. Among them, it can be set that the conveying part 31 sends the stacked objects in or out at regular intervals or by receiving signals, so as to better realize factory assembly line operation.

[0066] Specifically, referring to Figure 11 , the stacking mechanism includes a first monitoring component 8 for monitoring the stacking layer number and / or stacking height of the stacked objects. The first monitoring component 8 is connected to the conveying part 31. When the first monitoring component 8 sends out the operation completion signal, the conveying part 31 receives the operation completion signal and starts conveying. Among them, when the first monitoring component 8 monitors that the stacking layer number or height of the stacked objects reaches the fourth preset height 54, it sends an operation completion signal to the conveying part 31. After receiving this signal, the conveying part 31 starts conveying and conveys the stacked objects that have been stacked away.

[0067] Furthermore, referring to Figure 11 , the above-mentioned stacking device further includes: a second monitoring component 33, which is used to send a stacking signal when it monitors that the stacked object to be stacked is within the stacking operation area 32, and this signal is used to prompt that the stacking operation can be carried out.

[0068] Specifically, referring to Figure 11, the stacking workbench 3 includes a conveying part 31, and the second monitoring component 33 is connected to the conveying part 31. When the second monitoring component 33 emits a stacking signal, the conveying part 31 receives the stacking signal and stops conveying. Among them, when the conveying part 31 sends the stacked object to the stacking operation area 32, the second monitoring part emits a stacking signal, and after the conveying part 31 receives this signal, it stops conveying to facilitate the stacking operation.

[0069] Specifically, refer to Figure 11 , a positioner 34 is arranged at the stacking operation area 32. The positioner 34 is connected to the second monitoring component 33. When the second monitoring component 33 emits a stacking signal, the positioner 34 moves to block the movement of the stacked object in the stacking operation area 32. Among them, the positioner is used to prevent the stacked object from deviating from the operation position after entering the stacking operation area 32.

[0070] In the stacking device provided by the embodiment of the present invention, the stacking mechanism is arranged above the stacking operation area of the stacking workbench 3. When performing the stacking operation, the lifting mechanism 1 drives the holding mechanism 2 to lift and lower, so that the holding mechanism 2 drives the stacked object to lift and lower. During the lifting process, the holding mechanism 2 changes between the holding state and the releasing state at a preset position to complete the stacking operation. Compared with the manual stacking operation method in the prior art, the stacking mechanism of the embodiment of the present invention does not require manual stacking, thus saving manpower, improving the stacking operation efficiency, and being able to avoid situations such as stacking deviation and tipping that are likely to occur in manual stacking.

[0071] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
