Description

Coil caching system, automatic retrieval method for material coils

technical field

The invention relates to the technical field of automatic processing equipment, in particular to a material roll buffer system and a material roll automatic taking method.

Background technique

Material rolls are raw materials that are often used in processing and production, such as PVC material rolls, paper material rolls, leather material rolls, etc. Taking PVC material roll as an example, PVC material roll refers to the material roll of PVC film. The main component of PVC film is polyvinyl chloride, which is an important packaging material. In the process of automatic packaging operation, PVC material roll is an important consumable. The PVC material roll includes a material roll center tube located in the center and a PVC film wound on the material roll center tube.

During the packaging operation of the automated production line, it is necessary to use the manipulator to take the PVC material roll, and then use the manipulator to replace the material roll on the production line equipment. In the process of taking the PVC material roll by the manipulator, in order not to affect the plugging of the center tube of the material roll on the support shaft (expose the two ends of the center tube of the material roll, so as to facilitate the insertion of the support shaft), usually through the two sides of the PVC material roll Do the crawling work. For this kind of material roll replacement work in the automatic production line, if the PVC material roll is placed directly on the plane around the manipulator, since the PVC material roll will have pressure on the plane surface, under the reaction force of the pressure, the PVC material roll will Deformation will occur; this extrusion method is called bottom extrusion deformation. If the manipulator picks up by squeezing from both sides inward, during the lifting process of the PVC material roll, the extrusion deformation at the bottom of the PVC material roll will gradually disappear, which will easily cause the PVC material roll to be under the clamping force of the manipulator. Dimensional changes in direction, which in turn is not conducive to the smooth clamping of PVC rolls. If the pick-up method is adopted, it is unfavorable for the jaws of the manipulator to reach the bottom of the PVC material roll.

In addition to the above-mentioned problems in the picking process of PVC material rolls, they will also exist in some other types of material rolls.

Therefore, the first placement method in the above situation is unfavorable for the pick-up work of the material roll by the manipulator.

A manipulator with a specific structure is used to further restore the above-mentioned technical problems in detail. The Chinese patent application number 2021106049986 discloses a technical solution titled "An Automatic Refueling Robot". Refer to Figure 6 of this patent document for the clamping method of the material roll - since the distance between the lower ends of the two opposite clamping rods 4 is much smaller than the diameter of the new material roll 6 (material roll), it is possible to pick up the material roll Speaking of which, this picking method is also the inclusive picking method mentioned above. In this picking method, if the material roll is placed on a flat surface, it is easy to cause damage to the material roll during the picking process and it is also difficult to pick up. The above problems can be generalized in the prior art that the placement of the material rolls is inconvenient for the automatic access of the manipulator.
