Characteristics and classification of palletizing robot
The palletizing robot is the product of the organic combination of machinery and computer programs, which provides higher production efficiency for modern production. The palletizing machine is widely used in the palletizing industry. The palletizing robot greatly saves labor and space. The palletizing robot is flexible, accurate, fast, efficient, stable and efficient.
Features of palletizing robot
1. Simple structure and few parts. Therefore, the failure rate of parts is low, the performance is reliable, the maintenance is simple, and the inventory of parts required is small.
2. Small floor area. It is conducive to the layout of the production line in the customer's workshop, and a large warehouse area can be reserved. The palletizing robot can be set in a narrow space for effective use.
3. Strong applicability. When the size, volume, shape of the customer’s products and the overall dimensions of the pallet change, it is only necessary to make slight modifications on the touch screen, which will not affect the normal production of the customer. However, it is quite troublesome or even impossible to change the mechanical stacker.
4. Low energy consumption. Generally, the power of mechanical stacker is about 26KW, while that of stacking robot is about 5KW. The operation cost of customers is greatly reduced.
5. All controls can be operated on the screen of the control cabinet, which is very simple.
6. The teaching method is simple and easy to understand as long as the starting point and placement point are located.
Classification of palletizing robots
1. According to the structure
According to different mechanical structures, palletizing robots include the following three types: Cartesian, rotary joint and gantry crane.
① Cartesian palletizing robot: It is mainly composed of four parts: column, X arm, Y arm and gripper. It palletizes materials with four degrees of freedom (including three movement joints and one rotation joint). This type of stacker has simple structure, strong body rigidity and large carrying weight, and is suitable for stacking heavier materials.
② Rotary joint robot: the stacker rotates around the body, including four rotary joints: waist joint, shoulder joint, elbow joint and wrist joint. This type of stacker is programmed by teaching, that is, the operator holds the teaching box and controls the robot to move according to the specified action, so the movement process is stored in the memory, and it can be reproduced in the future automatic operation. This kind of robot has a small body and a large range of motion. It can stack one or several pallets at the same time. It can flexibly and flexibly work on multiple product production lines.
③ Gantry crane type: the robot arm mounted on the gantry crane is called gantry type palletizing robot, which has a large working range and can grasp heavier materials.
2. Divided according to stacking requirements
① Single layer stacking robot
The stacking robot with single layer structure is relatively basic. It mainly transports materials by conveyor belt. When it reaches the steering mechanism, it can be adjusted according to the specified direction. After preparation, it can enter the stacking mechanism. As long as the products are closely arranged in this place according to the set sequence, then the arranged products are transferred to the next station through the conveying roller, so that the stacking operation of the stacking robot is completed.
② Multilayer stacking robot
There must be multiple layers corresponding to a single layer, which must be more complex than a single layer stacking robot. We can see whether the pallet of the multi-layer palletizing robot is under the conveyor belt or can be fixed from left to right. When the machine is stacking, the materials will be neatly arranged on the carrier plate, and then the carrier plate will be set at the left limit position. When the materials conveyed by the conveyor belt are blocked by the baffle, they are arranged in one line. Then the pallet moves to the right, and the materials will be arranged in a line like the above steps. By analogy, the height of the lifting platform of the stacking robot will drop one layer for each additional layer of materials until the materials are stacked to a certain height.
③ Arranging and stacking robot
The palletizing robot is used to transport the materials in rows, and the push plate will put the transported materials on the aggregate table. Then move to the left and push upward to stack the three layers of materials together. In this process, there will be a slope device to ensure the smooth completion of the process, and the particularity of the aggregate table will also help the stacking robot to complete the stacking. These are just common palletizing robots.
