As shown in fig. 1 to 4, the present embodiment provides a stacking apparatus, which can be applied to a pallet stacking operation of a logistics warehouse, and the stacking apparatus includes a first lifting assembly 1, a second lifting assembly 2 and a support assembly 3.

Referring to fig. 1 and 2, each of the first lifting assembly 1 and the second lifting assembly 2 includes a first lifting mechanism 11 and a second lifting mechanism 12 arranged at intervals, and the first lifting mechanism 11 and the second lifting mechanism 12 are used for jacking the to-be-stacked piece 100. The first lifting mechanism 11 and the second lifting mechanism 12 both have a jacking end, a jacking path of the jacking end is a straight line, and the jacking end can be far away from the stacking object 100 to be transported when descending. The supporting component 3 comprises a first supporting plate 31 and a second supporting plate 32 with adjustable intervals, one end of the first supporting plate 31 is connected with the first lifting mechanism 11 of the first lifting component 1, the other end of the first supporting plate is connected with the second lifting mechanism 12 of the first lifting component 1, one end of the second supporting plate 32 is connected with the first lifting mechanism 11 of the second lifting component 2, the other end of the second supporting plate 32 is connected with the second lifting mechanism 12 of the second lifting component 2, and the first supporting plate 31 and the second supporting plate 32 are used for supporting the piled piece 200.

Specifically, at the time of stacking work, the first support plate 31 supports one end of the stacked member 200, and the second support plate 32 supports the other end of the stacked member 200. The first lifting mechanism 11 and the second lifting mechanism 12 of the first lifting assembly 1 support one end of the stack 100 to be stacked, and the first lifting mechanism 11 and the second lifting mechanism 12 of the second lifting assembly 2 support the other end of the stack 100 to be stacked. In the process of synchronously jacking the to-be-piled stack 100 by the first lifting assembly 1 and the second lifting assembly 2, the first supporting plate 31 can move towards the direction away from the piled stack 200 relative to the first lifting assembly 1, and the second supporting plate 32 can move towards the direction away from the piled stack 200 relative to the second lifting assembly 2, namely, the distance between the first supporting plate 31 and the second supporting plate 32 is increased, so that the first supporting plate 31 and the second supporting plate 32 are separated from the piled stack 200. When the stacked object 100 is in contact with and overlapped with the stacked object 200, and the first lifting mechanism 11 and the second lifting mechanism 12 of the first lifting assembly 1, and the first lifting mechanism 11 and the second lifting mechanism 12 of the second lifting assembly 2 are separated from the stacked object 100, the first supporting plate 31 and the second supporting plate 32 can simultaneously approach the stacked object 100, and the distance between the first supporting plate 31 and the second supporting plate 32 becomes smaller, so as to re-support the overlapped stacked object 100, that is, the stacked object 100 is completely stacked. The first lifting assembly 1 and the second lifting assembly 2 lift the next stacking object 100 again, and the above steps are repeated to stack a plurality of stacking objects 100 one by one.

The yard of this embodiment piles up the device, simple structure can constantly treat yard pile 100 through the continuous circulation lift of first lifting unit 1 and second lifting unit 2 and pile up, and the jacking route of the jacking end of first elevating system 11 and the jacking end of second elevating system 12 is the straight line, effectively shortens the jacking route of treating yard pile 100, improves yard pile efficiency. The jacking end can be far away from the stacking piece 100 to be stacked which is being transmitted when descending, so that the interference between the first lifting mechanism 11 and the second lifting mechanism 12 and the stacking piece 100 to be stacked which is being transmitted is prevented, namely, the jacking operation and the transmission operation of the stacking piece 100 are not influenced mutually, the operation time is fully utilized, the continuous automatic stacking of the stacking piece 100 to be stacked can be realized, the stacking efficiency of the stacking piece 100 to be stacked is effectively improved, manpower and material resources are saved, and the stacking cost is reduced.

It should be noted that the stacking apparatus provided in this embodiment can realize automatic stacking of the stacked stack 200 when the lifting paths of the lifting end of the first lifting mechanism 11 and the lifting end of the second lifting mechanism 12 move reversely along the original path.

As shown in fig. 1 and 4, the stacking apparatus may further optionally include a material conveying mechanism 4, the material conveying mechanism 4 is located between the first lifting assembly 1 and the second lifting assembly 2, and the to-be-stacked pile 100 is located on the material conveying mechanism 4. The material conveying mechanism 4 can continuously convey the to-be-stacked pieces 100 to the first lifting assembly 1 and the second lifting assembly 2, and the first lifting assembly 1 and the second lifting assembly 2 can continuously lift up the to-be-stacked pieces 100. Preferably, the material conveying mechanism 4 is a belt conveyor.

As shown in fig. 2, optionally, each of the first lifting mechanism 11 and the second lifting mechanism 12 includes a fixing member 111, a driving rod 112, and a lifting arm 113, wherein one end of the driving rod 112 is hinged to the fixing member 111, and the other end is hinged to the lifting arm 113. In this embodiment, the fixing member 111 and the driving rod 112, and the driving rod 112 and the lifting arm 113 are hinged by a pin. When the driving rod 112 rotates relative to the fixing member 111, the angle between the driving rod 112 and the lifting arm 113 can be adaptively changed by the hinge connection, so as to achieve the purpose of driving the lifting arm 113 to lift.

Further, one end of the lifting arm 113 away from the driving rod 112 can abut against the to-be-stacked stack 100, that is, the top end of the lifting arm 113 is a jacking end. When the driving rod 112 rotates relative to the fixing member 111, one end of the driving rod 112 away from the fixing member 111 drives the lifting arm 113 to lift up and down, so as to lift up the stacking object 100. Meanwhile, the lifting arm 113 can drive the first supporting plate 31 and the second supporting plate 32 to rotate relative to the fixing member 111 in the jacking process, so that the first supporting plate 31 and the second supporting plate 32 are separated from the piled piece 200, and the piled piece 100 to be piled is supported again. Specifically, one end of the first support plate 31 is rotatably connected to the fixing member 111 of the first lifting mechanism 11 of the first lifting assembly 1, the other end is rotatably connected to the fixing member 111 of the second lifting mechanism 12 of the first lifting assembly 1, one end of the second support plate 32 is rotatably connected to the fixing member 111 of the first lifting mechanism 11 of the second lifting assembly 2, and the other end is rotatably connected to the fixing member 111 of the second lifting mechanism 12 of the second lifting assembly 2.

In this embodiment, the fixing member 111 is fixedly connected to the rack on the production line, that is, the fixing member 111 is in a stationary state and does not move.

Optionally, the stacking device further comprises a driving mechanism, and an output end of the driving mechanism is connected with the driving rod 112 to drive the driving rod 112 to rotate relative to the fixing member 111. The driving mechanism may be a motor, etc., as long as it can drive the driving rod 112 to rotate relative to the fixing member 111.

It should be noted that the driving mechanism may drive the first lifting assembly 1 and the second lifting assembly 2 simultaneously, or may drive the first lifting assembly 1 and the second lifting assembly 2 separately, and the setting may be performed according to actual requirements.

Optionally, referring to fig. 2, each of the first lifting mechanism 11 and the second lifting mechanism 12 further includes a swing lever 114, and one end of the swing lever 114 is hinged to the fixing member 111, and the other end is hinged to the lifting arm 113. Specifically, the swing lever 114 is hinged to the middle of the lifting arm 113, and the fixing member 111, the driving rod 112, the lifting arm 113 and the swing lever 114 form a four-bar linkage structure. The swing lever 114 can prevent the lifting arm 113 from separating from the stacked object 100 during the lifting process, and limit the lifting arm 113. In this embodiment, preferably, the swing rod 114 is bent towards the stacking object 100 to form an arc shape, when the driving rod 112 drives the lifting arm 113 to lift, the swing rod 114 lifts along with the lifting arm 113, and meanwhile, an included angle between the swing rod 114 and the fixing member 111 and an included angle between the swing rod 114 and the lifting arm 113 are adaptively changed, so that the arc-shaped swing rod 114 can shorten a swing path traveled by the lifting arm 113 when the lifting arm 113 returns to an initial position, shorten a return time, and improve stacking efficiency. Meanwhile, the arc-shaped swing rod 114 can increase the space between the four-bar linkage structures, and the swing rod 114 is prevented from interfering with other components in the lifting process of the lifting arm 113.

In other embodiments, the swing lever 114 can be a straight lever as long as the normal operation of other components is not affected.

In this embodiment, a four-bar linkage structure is adopted to realize the lifting of the first lifting mechanism 11 and the second lifting mechanism 12, and in other embodiments, a slider-crank mechanism, a chain-type traction combination mechanism, or the like, or a combination of the above manners may be adopted to complete the lifting operation of the stacked object 100. The method for realizing continuous stacking by adopting different tracks through jacking and descending is in a protection range.

Alternatively, referring to fig. 2 and 4, the fixing member 111 includes a first rod 1111 and a second rod 1112 arranged at an included angle, an end of the first rod 1111 far from the second rod 1112 is rotatably connected to the first support plate 31 or the second support plate 32, and an end of the second rod 1112 far from the first rod 1111 is hinged to the driving rod 112. In this embodiment, the first rod 1111 and the second rod 1112 are disposed at an acute angle, that is, the second rod 1112 is inclined toward the side facing away from the material conveying mechanism 4, so that the second rod 1112 can be prevented from interfering with the material conveying mechanism 4.

As shown in fig. 2 and 3, optionally, two ends of each of first support plate 31 and second support plate 32 are provided with a support arm 311, and one end of support arm 311 away from first support plate 31 or second support plate 32 is hinged to one end of first rod 1111 away from second rod 1112. Taking the first support plate 31 as an example, the support arm 311 at one end of the first support plate 31 is hinged to the first rod 1111 of the first lifting mechanism 11 of the first lifting assembly 1, and the support arm 311 at the other end of the first support plate 31 is hinged to the first rod 1111 of the second lifting mechanism 12 of the first lifting assembly 1, so as to realize the rotational connection between the first support plate 31 and the first lifting assembly 1. In the process of lifting the to-be-stacked piece 100 by the lifting arm 113, the lifting arm 113 can drive the first support plate 31 and the second support plate 32 to move away from the stacked piece 200, that is, the support arm 311 rotates relative to the first rod 1111, so that the first support plate 31 and the second support plate 32 are far away from or close to the stacked piece 200.

In other embodiments, the supporting arm 311 and the first rod 1111 may be slidably connected. Specifically, the support arm 311 is provided with a guide protrusion, the first rod 1111 is provided with a sliding groove along the length direction, and the guide protrusion is in sliding fit with the sliding groove. During the lifting of the to-be-stacked member 100 by the lifting arm 113, the guide protrusions of the support arms 311 slide in the slide grooves to move the first support plate 31 and the second support plate 32 away from or close to the stacked member 200. That is, the distance between the first support plate 31 and the second support plate 32 may be adjusted, and is not limited to the rotational connection or the sliding connection described in the present embodiment.

Optionally, the first rod 1111 is provided with a third rod 1113, one end of the third rod 1113 away from the first rod 1111 is provided with a positioning pin 115, and the outer circumferential surface of the positioning pin 115 can abut against the supporting arm 311. The positioning pins 115 limit the positions of the first support plate 31 and the second support plate 32, and when the support arms 311 rotate to abut against the outer peripheral surfaces of the positioning pins 115, the positions of the first support plate 31 and the second support plate 32 are fixed, so as to stably support the stacked piece 200.

Optionally, the stacking apparatus further includes an elastic member having one end connected to the fixing member 111 and the other end connected to the supporting arm 311. When the lifting arm 113 lifts the stacked object 100, the lifting arm 113 drives the supporting arm 311 to rotate relative to the fixing member 111, the first supporting plate 31 and the second supporting plate 32 are both far away from the stacked object 200, and the elastic member is stretched and deformed. After stacking of the stacked pieces 100 is completed, the supporting arm 311 can rotate reversely relative to the fixing member 111 under the elastic force of the elastic member, so that the first supporting plate 31 and the second supporting plate 32 support the stacked pieces 100 again, and meanwhile, the supporting arm 311 abuts against the positioning pin 115 to limit the first supporting plate 31 and the second supporting plate 32. Preferably, the elastic member is a spring.

As shown in fig. 2, 3 and 4, optionally, the lifting arm 113 includes a main arm 1131 and a jacking arm 1132 disposed at one end of the main arm 1131, an end of the main arm 1131 away from the jacking arm 1132 is hinged to the driving rod 112, and the jacking arm 1132 is configured to support the to-be-stacked piece 100. In this embodiment, the jacking arm 1132 and the main arm 1131 are arranged at an obtuse angle, and the included angle between the jacking arm 1132 and the main arm 1131 is slightly larger than 90 degrees, that is, the jacking arm 1132 bends towards the stacking piece 100 to be stacked on the main arm 1131, and the edge of the stacking piece 100 to be stacked is overlapped on the jacking arm 1132. When the driving rod 112 drives the main arm 1131 to ascend and descend, the jacking arm 1132 jacks up the to-be-stacked piece 100.

Optionally, referring to fig. 3, guide rods 312 are disposed at two ends of first support plate 31 and second support plate 32, guide rod 312 and an edge of first support plate 31 or second support plate 32 define a guide slot 313, a toggle column 1133 is disposed on jacking arm 1132, and an end of toggle column 1133 far from jacking arm 1132 can extend into guide slot 313 and is in sliding fit with guide slot 313 to toggle first support plate 31 or second support plate 32 to rotate relative to fixing member 111. When the lifting arm 113 is lifted to a certain height, the toggle column 1133 of the lifting arm 1132 slides into the guide slot 313. As the lifting arm 113 is further lifted, the toggle pin 1133 is slidably engaged with the guide slot 313, and at the same time, an outward pushing force is applied to the guide rod 312, so that the first support plate 31 and the second support plate 32 are moved in a direction away from the stacked member 200 by the pushing force, i.e., the support arm 311 rotates relative to the first rod 1111 (at this time, the elastic member is stretched and deformed) until the first support plate 31 and the second support plate 32 are separated from the stacked member 200, as shown in fig. 6. The lifting arm 113 is further lifted, and when the to-be-stacked sheaf 100 is overlapped with the stacked sheaf 200, the toggle column 1133 is disengaged from the guide bar 312, and the lifting arm 113 is disengaged from the to-be-stacked sheaf 100. At this time, since the pushing force of the toggle column 1133 on the guide bar 312 is eliminated, the support arm 311 reversely rotates under the elastic reaction force of the elastic member, so that both the first support plate 31 and the second support plate 32 move toward the stacking object 100 of the just completed stacking to re-support the stacking object 100 of the completed stacking object, as shown in fig. 7.

Optionally, an end of the guide rod 312 away from the fixing member 111 is bent back to the stacked member 200 to form an arc-shaped bent portion, so that the toggle column 1133 can be smoothly separated from the guide rod 312, and the first support plate 31 and the second support plate 32 can be timely restored to the initial positions to support the stacked workpieces.

In other embodiments, the guide rods 312 may not be disposed on the first support plate 31 and the second support plate 32. At this time, in the process of jacking the stack 100 to be stacked, the lifting arm 113 can abut against the first support plate 31 and the second support plate 32 respectively at the two side edges of the stack 100 to be stacked, and along with the continuous rising of the stack 100 to be stacked, the first support plate 31 and the second support plate 32 can be pushed by the stack 100 to be stacked, so that the support arm 311 rotates relative to the first rod 1111, and the first support plate 31 and the second support plate 32 move in the directions away from each other. That is, the interval between the first support plate 31 and the second support plate 32 becomes larger, and both the first support plate 31 and the second support plate 32 are separated from the stacked member 200. Likewise, when the to-be-stacked sheaf 100 overlaps the stacked sheaf 200, both the lifting arm 113 of the first lifting assembly 1 and the lifting arm 113 of the second lifting assembly 2 are disengaged from the to-be-stacked sheaf 100. At this time, since the thrust action of the both side edges of the to-be-stacked piece 100 to the first support plate 31 and the second support plate 32 disappears, the support arms 311 reversely rotate under the elastic reaction force of the elastic member, so that the first support plate 31 and the second support plate 32 both move toward the to-be-stacked piece 100 which has just completed stacking, and the interval between the first support plate 31 and the second support plate 32 becomes small to re-support the to-be-stacked piece 100 which has completed stacking.

Taking the tray used in the logistics storage as an example, the stacking device provided by the embodiment has the following working process:

in the initial state, as shown in fig. 4, the first support plate 31 and the second support plate 32 support a plurality of stacked trays, the stacked trays are located on the material conveying mechanism 4, the lifting arm 113 is at the lowest state, and at this time, the lifting arm 1132 is not in contact with the stacked trays. Starting the driving mechanism, as shown in fig. 5, the driving rod 112 of the first lifting assembly 1 and the driving rod 112 of the second lifting assembly 2 respectively rotate relative to the fixing member 111 along the arrow direction in the figure, and simultaneously drive the lifting arm 113 to rise, at this time, the lifting arm 1132 abuts against the edge of the tray to be stacked.

The driving rod 112 continues to rotate in the direction of the arrow in the figure, the lifting arm 113 continues to rise, as shown in fig. 6, at this time, the tray to be stacked overlaps the stacked tray, and the toggle column 1133 on the lifting arm 1132 slides into the guide slot 313, and under the thrust action of the toggle column 1133 on the guide rod 312, the supporting arm 311 rotates relative to the fixing member 111, so that the first supporting plate 31 and the second supporting plate 32 both move in the direction away from the stacked tray. In the illustrated state, the first support plate 31 and the second support plate 32 are about to be separated from the edge of the stacked tray.

The driving rod 112 continues to rotate, the lifting arm 113 continues to rise again, as shown in fig. 7, at this time, the lifting arm 113 has risen to the highest position, the toggle column 1133 has disengaged from the guide rod 312, the stacking tray and the stacked tray are completely overlapped, and the first supporting plate 31 and the second supporting plate 32 have both recovered to the initial state under the elastic reaction force of the elastic member, and re-support the stacking tray which is completed stacking.

As shown in fig. 8, the driving rod 112 continues to rotate in the direction of the arrow, and the lifting arm 113 starts to descend until the lifting arm 113 returns to the initial position, i.e., the position shown in fig. 4. And then, starting a new cycle again, rotating the driving rod 112, and lifting the next pallet to be stacked by the lifting arm 113 again, and repeating the cycle to realize the continuous stacking operation of the pallet to be stacked.

In other embodiments, the stacking device can stack the materials such as the plates. The stacking device can be used for automatically stacking materials which are repeatedly stacked.

As shown in fig. 9, a lifting track of the lifting arm 113 is given, the lifting arm 113 runs along a vertical line when jacking the tray to be stacked, the lifting arm 113 runs along an arc-shaped curve when returning to the initial position, the whole track of the lifting arm 113 is "D" shaped, and the lifting arm 113 does not need to avoid the tray to be stacked on the material conveying mechanism 4 when returning to the initial position. Both can convey simultaneously and treat a yard pile tray, can realize treating the continuous sign indicating number pile of a yard pile tray again, effectively improve tray sign indicating number pile efficiency.
