The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides the following embodiments:

example 1

the stacking device comprises a stacking frame 1, a detection device 2, a first telescopic device 3 and a processor 4;

the stacking rack 1 includes:

a base, a first side wall 101, a second side wall 102, a third side wall 103, a plurality of sets of support members 104 and support bars 7;

wherein the supporting rod 7 is arranged on the base, and the height of the supporting rod 7 is higher than the lowest height of the support member 104;

one set of support members 104 includes: the first support plate 1041 is arranged between the first side wall 101 and the second side wall 102, the second support plate 1042 is arranged between the first side wall 101 and the third side wall, the first support plate 1041 and the second support plate 1042 are arranged symmetrically, a gap between the first support plate and the second support plate forms a support surface, and the support surface is used for supporting a plate; wherein the first support plate 1041 and the second support plate 1042 have a rotation shaft 1043 such that the support plates can rotate around the rotation shaft 1043;

the detection device 2 is arranged on one side of the support member 104 and can detect whether the plate enters the support member 104;

The stacking method implemented by the stacking device disclosed by the embodiment comprises the following steps:

step S2: the sheets of the support member 104 in the stack 1 are stacked.

Specifically, the loading manner in step S1 is: s11: lowering the stack 1 to the level of the topmost support member 104 and the conveyor transporting the sheet material so that the sheet material above the conveyor can slide over the support members 104; s12: the detection device 2 recognizes that the plate is loaded to the topmost supporting member, and sends a signal to the processor 4 to enable the processor to control the first telescopic device 3 to drive the stacking rack 1 to move upwards; s13: the stacking rack 1 moves upward so that the height of the secondary top supporting member 104 is the same as the height of the conveyor belt conveying the sheet material, and the sheet material above the conveyor belt can slide above the secondary top supporting member 104; s14: this is repeated until the loading of all the plates of the support member 104 of the stack 1 is completed;

the stacking mode in the step S2 is as follows:

in this step, since the support members 104 are rotated upward, the support members are inclined upward, the space between the support members 104 disposed in bilateral symmetry becomes large, and the plate material slides downward out of the support members 104;

s24: the support bar 7 causes the sub-bottom support member 104 to rotate upward, and causes the sheet material on the sub-bottom support member 104 to slide downward off the support member and to be stacked onto the sheet material in step S22.

In the embodiment, the plates conveyed on the conveying belt are loaded on each group of supporting members 104 of the stacking rack, and because only one plate is loaded on each group of supporting members 104, the abrasion, collision and the like caused by the existence of friction force between two plates when the plates slide from the conveying belt to the supporting members 104 are avoided; meanwhile, only one plate is loaded on each group of supporting members 104, so that the pressure of the plate on the supporting members is reduced, and the deformation of the connecting parts of the supporting members 104 is avoided. Meanwhile, when the stacking is completed after loading, the supporting member 104 is rotatable, and in the process of descending the stacking rack, the supporting member 104 is abutted against the supporting rod 7 and rotates upwards under the abutting of the supporting rod 7, the plates automatically slide off the supporting member 104 and are separated from the supporting member, the stacking of the plates is completed, the stacking device is simple in structure, and the plates vertically move on the supporting member during stacking, so that the traditional horizontal movement is replaced, the friction is reduced, and the loss of the plates is reduced.

Example 2

In this example, as a further improvement of the technical means of example 1, the present invention is characterized in that,

a set of eccentric wheels 8 is arranged between every two adjacent upper and lower sets of supporting members 104, as shown in fig. 1, the eccentric wheels 8 are parallel to the supporting members 104, and the gravity centers of the eccentric wheels 8 are eccentric to the opposite sides of the plate.

When the plates are stacked, the supporting rod 7 abuts against the supporting member 104, so that the supporting member 104 rotates upwards and abuts against the eccentric wheel, the plates slide off the supporting member 104 along with the continuous rotation of the supporting member 104, and the eccentric wheel rotates upwards, so that the plates are clamped between the two eccentric wheels which are symmetrical left and right; as the stacking platform continues to descend, the sheet stacking platform 5 or the sheet above the sheet stacking platform 5 pushes the sheet between the two sets of eccentric wheels 8 upwards, so that the sheet is separated from the eccentric wheels 8, and the stacking is completed.

In this embodiment, when the supporting rod 7 jacks up the supporting member 104 to cause the supporting member 104 to rotate, the sheet material does not directly fall vertically into the stacking platform, but is clamped and held by a set of eccentric wheels to stack stably, so as to buffer the sheet material, and avoid the damage caused by collision when the sheet material falls vertically.

Preferably, two ends of the eccentric wheel 8 are provided with torsion springs 801;

after the eccentric wheel 8 rotates, the torsion spring 801 can drive the eccentric wheel 8 to return to the initial position before rotation.

In some embodiments, the two ends of the eccentric wheel are provided with the torsion springs 801, and in the actual plate stacking process, the eccentric wheel 8 can reset by means of the elasticity of the torsion springs 801 after rotating, so that the situation that the eccentric wheel 8 cannot reset by means of self gravity due to an overlarge rotating angle after being pushed upwards by the plates is avoided.

In the embodiment, the plate stacking platform is specially arranged and is connected with the second telescopic device and can vertically move up and down; when the plates are stacked, the supporting member 104 can control the plate stacking platform to move up and down, and the stacked plates can be conveniently transferred.

Example 4

In this example, as a further improvement of the technical means of example 3, the present invention is characterized in that,

the support rod 7 comprises an upper support section 701 and a lower support section 702;

the upper supporting section 701 is a part of the supporting rods 7 above the horizontal plane of the plate stacking platform 5, and the lower supporting section 702 is a part of the supporting rods 7 below the horizontal plane of the plate stacking platform 5;

the lower support section 702 has a length greater than the height at which the stacking rack 1 can be lowered.

In the embodiment, the length of the supporting rod 7 below the horizontal plane of the plate stacking platform 5 is greater than the distance between the bottommost supporting member 104 and the topmost supporting member 104, so that when the stacking rack 1 descends to the lowest height, the supporting member 104 is still in the state after the supporting member 104 rotates upwards by the lower supporting section 702 of the supporting rod 7, and the situation that when the subsequent stacking rack 1 ascends, the supporting member 104 is blocked by the supporting rod 77 and cannot ascend automatically due to the fact that the supporting member 104 resets after descending to the lower side of the plate stacking platform 5 is avoided.

Example 5

In this example, as a further improvement of the technical means of example 2, the present invention is characterized in that,

a groove 1045 is formed in one side of the first supporting plate 1041 and the second supporting plate 1042 facing to the middle part of the stacking rack 1;

the length of the groove in the length direction of the eccentric wheel 8 connecting shaft is D1;

wherein D1> D2, and the first supporting plate 1041 or the second supporting plate 1042 rotates upward, so that the eccentric wheel 8 is located in the groove.

In this embodiment, a groove 1045 is formed in one side of the first support plate 1041 and the second support plate 1042 facing the middle of the stacking rack 1, and a length D1 of the groove 1045 in the length direction of the connecting shaft of the eccentric wheel 8 is greater than a length D2 of the eccentric wheel 8 in the length direction of the connecting shaft, so that the first support plate 1041 or the second support plate 1042 rotates upward, the eccentric wheel 8 can be located in the groove 1045, and the situation that the plate cannot be clamped between the eccentric wheels 8 when the first support plate 1041 or the second support plate 1042 rotates upward is effectively avoided.

Example 6

the first push plate 1001 and the second push plate 1002 are respectively connected with two ends of the third telescopic device 10;

the telescopic device is connected with the first side wall 101 through a connecting member 1043.

When transporting plates through the conveyor belt, the plates enter the stacking frame 1, the distance between the plates and the second side wall 102 or the third side wall 103 of the stacking frame 1 is possibly different, the plates enter different layers of supporting members 104 and are not aligned on the side faces of the plates on different layers, and after the plates are stacked in the stacking frame 1, the side faces of the plates on all layers are not aligned, so that the plates after being stacked are not facilitated to enter the packaging box.

Therefore, the second telescopic device 6, the first push plate 1001 and the second push plate 1002 are arranged in the embodiment, after the stacking of the plates in the stacking frame 1 is completed, the second telescopic device 6 above the stacking frame 1 can be controlled by the processor 4 to be shortened, the distance between the first push plate 1001 and the second push plate 1002 is reduced, the plates are pushed, the side surfaces of the plates are aligned, and the subsequent plates after stacking are conveniently packaged.

Example 7

the difference between the distance between the second side and the third side and the width of the plates to be stacked is more than 4cm.

Considering that when the sheet material is transported by the conveyor belt, the sheet material on the conveyor belt needs to have a certain distance with the plane of the second sidewall 102 or the third sidewall 103 of the stacking rack 1, and the sheet material can enter the stacking rack 1, and if the position of the sheet material above the conveyor belt is shifted during the transportation process, the sheet material may collide with the second sidewall 102 or the third sidewall 103, and the subsequent stacking cannot be performed.

Therefore, in the embodiment, the difference between the distance between the second side wall 102 and the third side wall 103 and the width of the plate to be stacked is set to be greater than 4cm, so that the plate above the conveyor belt can enter the stacking rack 1 even when the plate has a small deviation, and the stacking is completed.

Considering that the plate material has a certain speed after entering the stacking rack 1, the plate material may collide with the first side wall 101 of the stacking rack 1 after completely entering the stacking rack 1, and the plate material may be damaged.

In the embodiment, the elastic body 9 is disposed on the inner side of the first side wall 101 of the stacking rack 1, and after the sheet material completely enters the stacking rack 1, the sheet material will contact with the elastic body 9 on the inner side of the stacking rack 1, so that a rigid collision between the sheet material and the first side wall 101 can be effectively avoided, and in order to achieve the contact between the sheet material and the elastic body 9, the sheet material can also contact with the touch sensor 2 above the supporting member 104.
