Description

Technical Field

[0001] This utility model belongs to the field of kiln equipment technology, and specifically relates to a brick conveying device for manual stacking of bricks. Background Technology

[0002] For example, patent application number CN202221202089.6 discloses a double-clamp automatic palletizing and packaging system, including a chain conveyor, a brick blank sorting machine, a double-clamp palletizer, a pallet transfer machine, and a piercing and binding machine. The brick blank sorting machine is installed at the rear of the chain conveyor in the same direction as the conveying. The chain conveyor has a manual brick loading position for manually placing brick blanks from the kiln car onto the chain conveyor assembly. Two pallet transfer machines are symmetrically installed vertically at the rear of the brick blank sorting machine. A double-clamp palletizer is installed above the brick blank sorting machine and the two pallet transfer machines. The rear of the brick blank sorting machine has a blank gripping position for the two palletizing clamps of the double-clamp palletizer to grip and stack the brick blanks. Each pallet transfer machine has a stacking position, a rotating packaging position, a storage position, and a pallet turnover position in sequence for stacking, packaging, and transporting brick blanks on the pallet. Each pallet transfer machine has a piercing and binding machine installed at the rotating packaging position for binding and packaging the stacked brick blanks. The chain conveyor is equipped with a conveyor frame, a chain conveyor assembly, a power assembly, and a brick-stopping assembly. The chain conveyor assembly has a long conveyor chain and a short conveyor chain. Both ends of the long and short conveyor chains are mounted on the conveyor frame via a power roller and a driven roller. The gap between the long and short conveyor chains forms a manual brick-loading position. The power roller is connected to the power assembly, which uses a motor and reducer to convey the brick blanks to the brick blank sorting machine. The brick-stopping assembly uses a brick-stopping plate, which is installed on the conveyor frame on one side of the long conveyor chain to align the brick blanks. The brick blank sorting machine is equipped with a sorting bracket, a roller assembly, a roller power assembly, a brick-grabbing trolley assembly, and a brick-grabbing trolley power assembly. The roller assembly is rotatably mounted on the sorting bracket on both sides, and receives the brick blanks from the chain conveyor assembly. One side of the roller assembly is connected to the roller power assembly, which is installed on the lower inner side of the sorting bracket. The roller power assembly uses a motor and reducer to drive the roller assembly to rotate and convey the brick blanks to the center position below the double-clamp palletizer.

[0003] The packaging process for bricks involves the use of brick conveyors and brick sorting machines. Bricks are manually placed onto the brick conveyor (chain conveyor), and after being neatly arranged by the brick sorting machine, they are picked up and stacked by a palletizer. The aforementioned patent utilizes a brick sorting machine to sort the bricks.

[0004] In addition, the specific structure of the brick sorting machine can also be found in patent application number CN202220906957.2, which discloses a belt-type brick sorting machine. Its features include a belt conveyor mechanism, a roller conveyor mechanism, an end-blocking mechanism, a brick cleaning mechanism, and a frame. The belt conveyor mechanism includes a front belt conveyor mechanism and a rear belt conveyor mechanism that are adjacent to each other and have the same structure. The belt conveyor mechanism is equipped with a belt motor and a flat belt for conveying bricks. The brick cleaning mechanism is installed between the front and rear belt conveyor mechanisms and is equipped with a brush for cleaning debris from the top of the bricks. The roller conveyor mechanism is installed on the frame and behind the rear belt conveyor mechanism. The roller conveyor mechanism is equipped with a roller motor and a power roller for conveying bricks. The end-blocking mechanism is installed at the rear of the frame and is equipped with an adjusting cylinder, a secondary positioning cylinder, and a brick stopper. The brick stopper is installed on the cylinder rod of the secondary positioning cylinder, which is installed on a movable frame. The movable frame is installed on the cylinder rod of the adjusting cylinder for two-stage blocking and limiting of the bricks on the power roller.

[0005] In existing technology, bricks are aligned on one side by a blocking and positioning mechanism to facilitate gripping by the palletizer's clamps. However, bricks on the brick conveyor are manually placed, which may not be neat or regular. When the blocking and positioning mechanism performs positioning, the bricks may scatter (mainly moving to the sides), exceeding the clamping range of the clamps in the left and right directions, resulting in clamping failure. Summary of the Invention

[0006] To address the aforementioned problems, this utility model embodiment primarily employs two methods: firstly, a positioning and guiding mechanism is incorporated into the conveying structure; secondly, an anti-scattering mechanism is installed in the sorting structure, ensuring a high success rate of gripping.
