Description

Technical Field

[0001] The present invention relates to the technical field of brick product packaging machinery, and in particular to an intelligent layered depalletizer for brick stacks. Background Art

[0002] Currently, most domestic sintered brick manufacturers still rely on manual handling or simple machine-assisted operations for packaging and transporting finished products, resulting in high production costs and low efficiency. Existing depalletizer lifting mechanisms generally lack buffering devices, resulting in large lifting movements that are difficult to precisely control and operate. Furthermore, the chucks lack synchronization devices, making it difficult to evenly distribute force on both sides during the clamping process, resulting in poor clamping reliability.

[0003] A Chinese patent application with application number 201611106410.X and publication date May 10, 2017, discloses a depalletizer. The depalletizer includes a frame, a traveling mechanism suspended from the frame, a lifting mechanism fixedly connected to the traveling mechanism, and a gripping mechanism rotatably connected to the lower end of the lifting mechanism. The lifting mechanism utilizes a sprocket for buffering lifting and lowering, and the gripping mechanism's grippers are equipped with a synchronization device.

[0004] However, when the unloader unloads bricks, the clamping plate clamps part of the bricks on each layer, and then the lifting cylinder drives the lifting column to move upward, so that the clamping plate drives the clamped bricks of the corresponding layer to move upward; the unloader only clamps the bricks to be unloaded by the clamping plate and unloads the bricks layer by layer from the top of the brick pile to the bottom; when unloading bricks, the remaining bricks below the bricks to be unloaded are not fixed; thus, the brick unloading effect is poor.

[0005] Because existing fired bricks are generally separated from the crisscross stacks of bricks and then stacked again for packaging; however, the fired bricks will stick to each other; the bricks will generate mutual pulling forces; and the position of the stuck bricks is unknown and can only be discovered during the unloading process.

[0006] If the destacker is used to unload bricks, when the bricks of the first layer are adhered to the bricks of the second layer, although the plywood clamps the bricks of the first layer and lifts it up, some bricks of the first layer are adhered to some bricks of the second layer, which will cause one of the bricks of the second layer to rise with the bricks of the first layer. In this way, it is necessary to manually clean the adhered bricks so that the bricks of the first layer can be placed stably in layers. However, when one of the bricks of the second layer is missing, the bricks of the second layer cannot be clamped by the plywood. This is because the plywood clamps the bricks by applying pressure on both sides of a layer of bricks to create contact pressure between the bricks of a layer, thereby clamping the layer of bricks. When one of the bricks of a layer is missing, some bricks cannot create contact pressure between each other, thus failing to drive the entire layer of bricks to rise.

[0007] At the same time, when the first layer of bricks is adhered to the second layer of bricks, the plywood will clamp the first layer of bricks during the rising process, because some bricks of the first layer of bricks are adhered to the second layer of bricks, resulting in some bricks of the first layer unable to rise; the first layer of bricks is gradually rising, but the bricks adhered to the second layer of bricks gradually move down relative to the rising first layer of bricks; when the first layer of bricks rises to a certain height, the bricks adhered to the second layer of bricks will separate from the first layer of bricks; the first layer of bricks will not be able to clamp the entire layer during the rising process due to lack of bricks, causing bricks to scatter; this will cause the clamping parts to be unable to move the entire layer of bricks to the leather conveyor; at the same time, manual cleaning of fallen bricks is required; at the same time, falling bricks will create certain safety hazards.

[0008] The unloader has poor brick unloading effect and requires manual intervention. At the same time, in order to ensure the safety of brick cleaning, the unloader needs to be stopped before it can be carried out. Frequent stops will lead to low working efficiency of the unloader. Summary of the Invention

[0009] The present invention provides an intelligent layered brick stack unloader which has high working efficiency, does not require manual intervention and has good brick unloading effect.

[0010] To achieve the above-mentioned purpose, the technical solution of the present invention is: an intelligent layered brick stack unloading machine, comprising a frame on which a first brick unloading device, a second brick unloading device and a lifting platform are provided.

[0011] The first brick unloading device includes a transverse clamping mechanism and a transverse pushing mechanism; the transverse pushing mechanism is located below the transverse clamping mechanism; the transverse clamping mechanism includes a first clamping mechanism and a second clamping mechanism; the first clamping mechanism and the second clamping mechanism are symmetrical about the lifting platform; the lifting platform is located between the first clamping mechanism and the second clamping mechanism.

[0012] The second brick unloading device includes a longitudinal clamping mechanism and a longitudinal pushing mechanism; the longitudinal pushing mechanism is located below the longitudinal clamping mechanism; the longitudinal clamping mechanism includes a third clamping mechanism and a fourth clamping mechanism; the third clamping mechanism and the fourth clamping mechanism are symmetrical about the lifting platform; the lifting platform is located between the third clamping mechanism and the fourth clamping mechanism.

[0013] The above settings are because brick stacks are generally stacked in a crisscross pattern for sintering; by setting

[0014] The first brick unloading device and the second brick unloading device are movable along the X-axis and Y-axis of the frame; thus, the coordination effect between the unloader and the brick stack is good and the working efficiency is high.

[0015] By setting up a transverse clamping mechanism and a transverse pushing mechanism, and the transverse pushing mechanism is located below the transverse clamping mechanism, the transverse pushing mechanism and the transverse clamping mechanism will not interfere with each other when working, and the cooperation effect is good. The transverse clamping mechanism is used to clamp the transversely stacked bricks; the transverse pushing mechanism is used to unload the longitudinally stacked bricks below the transversely stacked bricks; when the brick stack is clamped, the transverse pushing mechanism will then unload the bricks; this will prevent the bricks from sticking together and causing poor brick unloading effect; at the same time, the transverse clamping mechanism can fix the brick stack, preventing the brick stack from moving when the transverse pushing mechanism unloads the bricks, which may cause the brick stack to collapse; and because the transverse pushing mechanism moves along the X-axis of the frame, the contact area between the transverse pushing mechanism and the longitudinally stacked bricks is large, which improves the brick unloading effect.

[0016] By setting up a longitudinal clamping mechanism and a longitudinal pushing mechanism, and with the longitudinal pushing mechanism located below the longitudinal clamping mechanism, the longitudinal pushing mechanism and the longitudinal clamping mechanism will not interfere with each other during operation, achieving a good coordination effect. The longitudinal clamping mechanism is used to clamp the horizontally stacked bricks; the longitudinal pushing mechanism is used to unload the horizontally stacked bricks below the longitudinally stacked bricks; after the brick stack is clamped, the longitudinal pushing mechanism proceeds to unload the bricks; this prevents the bricks from sticking together, resulting in poor unloading effect; at the same time, the longitudinal clamping mechanism can fix the brick stack, preventing the brick stack from moving when the longitudinal pushing mechanism unloads the bricks, which could cause the brick stack to collapse; at the same time, the longitudinal pushing mechanism moves along the X-axis of the frame, and the contact area between the longitudinal pushing mechanism and the horizontally stacked bricks is large, resulting in a good unloading effect.
