Description

Brick stacking auxiliary device

Technical Field

The invention belongs to the technical field of machinery, and particularly relates to a brick stacking auxiliary device.

Background

Bricks produced by a brick making factory are transported by a conveyor belt, taken down by workers at the tail end of the conveyor belt, put on a transfer plate with a specific size specification and piled into a brick pile, and finally the brick pile and the transfer plate are packed and transported away together. In the process, workers need to manually take off scattered bricks on the conveyor belt, and the labor intensity is high. Although manipulators for transferring bricks are known in the art, the current manipulators can only transfer a single or a plurality of fixed bricks, and the current manipulators are difficult to handle for scattered bricks which move on a conveyor belt and are variably spaced from one another.

Disclosure of Invention

The invention aims to provide a brick stacking auxiliary device, so that the existing manipulator can replace manual work to transfer bricks on a conveyor belt to a transfer plate, and the labor cost is reduced.

The brick stacking auxiliary device comprises a conveyor belt and a rack positioned at the tail end of the conveyor belt and connected with the conveyor belt, and is characterized in that a plurality of freely rotating conveying shafts are arranged on the rack at intervals, and the axial direction of each conveying shaft is perpendicular to the conveying direction of the conveyor belt; the rack is equipped with the fragment of brick position detector that is used for detecting the fragment of brick position in the one end of keeping away from the conveyer belt, the actuating mechanism of fragment of brick position detector and conveyer belt links to each other with the controller respectively.

When bricks move to the tail end from the conveyor belt, the bricks move to the rack connected with the conveyor belt under the pushing of the conveyor belt and stay on the conveying shaft on the rack, and subsequent bricks on the conveyor belt can contact the conveyor belt and push the conveyor belt to continue to move on the conveying shaft, so that the rack is gradually full of bricks, and the intervals among the bricks are very small. When the foremost brick reaches the end, far away from the conveyor belt, of the rack, the brick position detector is triggered, the brick position detector sends a signal representing that the brick on the rack is full to the controller, the controller immediately stops the driving mechanism of the conveyor belt to enable the conveyor belt to stop moving temporarily, and at the moment, a worker can control the manipulator to transfer the brick on the rack to the transfer plate at one time. When the brick position detector detects that the brick on the rack is transferred away by the manipulator, a signal representing that the brick on the rack is transferred away is sent to the controller, and the controller immediately starts the driving mechanism of the conveyor belt to enable the conveyor belt to continue to move.

Further, the brick position detector has two kinds:

1. the brick position detector is composed of a laser generator and a laser receiver which are respectively arranged on two sides of the machine frame. The laser generator is opposite to the laser receiver, and the laser emitted by the laser generator is received by the laser receiver; when the bricks on the rack move to one end of the rack, which is far away from the conveyor belt, the bricks are positioned on the laser moving route, so that the laser is prevented from irradiating the laser receiver, and the laser receiver cannot receive the laser, namely, a signal representing that the bricks on the rack are full is sent to the controller; accordingly, after a brick on the rack is transferred away by the robot, the laser receiver receives the laser, i.e., sends a signal to the controller indicating that the brick on the rack has been transferred away.

Further, in order to prevent the bricks from falling out of the rack under the action of inertia, a brick blocking structure for blocking the bricks is arranged at one end, far away from the conveyor belt, of the rack. Particularly, the brick blocking structure is a baffle or a blocking column which is arranged on the top surface of the rack in a protruding mode, and the height of the baffle or the blocking column is lower than that of the brick blocks, so that interference on a manipulator is avoided.

2. The brick position detector is a travel switch fixed on the top surface of the rack, and a contact end of the travel switch faces the direction of the conveyor belt. When the bricks on the rack move to one end of the rack far away from the conveyor belt, the bricks abut against a contact of the travel switch, and the travel switch is closed; after the bricks on the rack are transferred away by the manipulator, the contact of the travel switch loses the abutting of the bricks, the travel switch is automatically disconnected, and the controller can judge that the bricks on the rack are full or the bricks on the rack are transferred away by detecting the closing and opening states of the travel switch. The travel switch can also play a role in blocking bricks from falling off the rack.

The brick stacking auxiliary device can automatically arrange scattered bricks on the conveying belt into compact brick rows, so that the brick rows can be conveniently transferred onto the transfer plate by a manipulator, the brick factory can realize the offline and stacking operation of the bricks without additionally improving the manipulator, the labor expenditure of the brick factory can be reduced, and the economic benefit of the brick factory can be improved.

Detailed Description

The following describes embodiments of the present invention, such as shapes and structures of respective members, mutual positions and connection relationships between respective portions, and actions and operation principles of the respective portions, in further detail, with reference to the accompanying drawings.

Example 1:

this embodiment provides a sign indicating number brick auxiliary device to make present manipulator can replace the manual work to shift the fragment of brick on the conveyer belt to the board that conveys, thereby reduce the cost of labor.

As shown in fig. 1, the brick stacking auxiliary device of this embodiment includes conveyer belt 1 and the frame 2 that is located conveyer belt 1 end and meets with the conveyer belt, and the top interval of frame 2 is equipped with a plurality of free rotation's horizontal conveying axle 3, and the interval of adjacent conveying axle 3 is less than the width of fragment of brick 4 to avoid fragment of brick 4 to drop from the clearance department of adjacent conveying axle 3. The axial direction of the conveying shaft 3 is perpendicular to the conveying direction of the conveyor belt 1, so that the conveying direction of the conveying shaft 3 is consistent with the conveying direction of the conveyor belt 1 (the arrow direction in the figure); the top surface of the transfer shaft 3 is flush with the top surface of the conveyor belt 1 to facilitate movement of the bricks 4 from the conveyor belt 1 onto the transfer shaft 3.

The frame 2 is equipped with the fragment of brick position detector 5 that is used for detecting 4 positions of fragment of brick in the one end of keeping away from conveyer belt 1, fragment of brick position detector 5 and conveyer belt 1's actuating mechanism link to each other with the controller respectively. In the present embodiment, the brick position detector 5 is constituted by a laser generator and a laser receiver which are respectively provided on both sides of the rack 2. The laser generator is opposite to the laser receiver, and the laser emitted by the laser generator is received by the laser receiver; when the bricks 4 on the rack 2 move to one end of the rack 2 far away from the conveyor belt 1, the bricks 4 are positioned on the moving route of the laser, so that the laser is prevented from irradiating the laser receiver, and the laser receiver cannot receive the laser, namely, a signal representing that the bricks 4 on the rack 2 are full is sent to the controller; accordingly, when a brick 4 on the rack 2 has been transferred away by the robot, the laser receiver receives the laser, i.e. sends a signal to the controller indicating that "brick 4 on the rack 2 has been transferred away".

As shown in fig. 2, when a brick 4 travels from the conveyor belt 1 to the end, it will move to the frame 2 connected to the conveyor belt 1 under the push of the conveyor belt 1 and stay on the conveying shaft 3 of the frame 2, and the subsequent brick 4 on the conveyor belt 1 will contact with it and push it to travel on the conveying shaft 3, so that the frame 2 is gradually full of bricks 4 and the space between the bricks 4 is very small. When the foremost brick 4 reaches the end of the rack 2 far away from the conveyor belt 1, the brick position detector 5 is triggered, the brick position detector 5 sends a signal representing that the brick 4 on the rack 2 is full to the controller, the controller immediately stops the driving mechanism of the conveyor belt 1 to make the conveyor belt 1 stop moving temporarily, and at the moment, a worker can control the manipulator to transfer the brick 4 on the rack 2 to the transfer plate at one time. When the brick position detector 5 detects that a brick 4 on the rack 2 has been transferred away by the robot, it sends a signal indicating that "the brick 4 on the rack 2 has been transferred away" to the controller, and the controller then activates the driving mechanism of the conveyor belt 1 to continue the travel of the conveyor belt 1.

If the conveying speed of the conveyor belt 1 is high, a brick blocking structure for blocking bricks 4, for example, a baffle plate protruding from the top surface of the frame 2 can be arranged at one end of the frame 2 far away from the conveyor belt 1, and the height of the baffle plate is lower than that of the bricks 4, so as to avoid interference on a manipulator. Of course, if the conveyor belt 1 is slow in its conveying speed, the bricks 4 on the frame 2 will also be slow in its travel speed, in which case no blocking structure needs to be provided.

Example 2:

unlike embodiment 1, in this embodiment, the brick position detector 5 is a travel switch fixed to the top surface of the rack 2, the contact end of the travel switch facing the conveyor belt 1. When the bricks 4 on the rack 2 move to one end of the rack 2 far away from the conveyor belt 1, the bricks 4 abut against a contact of a travel switch, and the travel switch is closed; after the bricks 4 on the rack 2 are transferred away by the manipulator, the contact of the travel switch loses the abutting of the bricks 4, the travel switch is automatically disconnected, and the controller can judge that the bricks 4 on the rack 2 are full or the bricks 4 on the rack 2 are transferred away by detecting the on and off states of the travel switch. The travel switch also serves to block bricks 4 from falling off the frame 2.
