Description

Technical Field

[0001] The present invention relates to separating plastic pallets, and in particular to a method for separating plastic pallets. Background Art

[0002] Most products need to be packaged on pallets before transportation, that is, multiple products are positioned in an orderly manner on the pallet. During the automated packaging process of the products, the pallets need to be removed before the products are loaded. However, since the pallets are stacked together, it is easy for more than two pallets to be adsorbed together when the pallet is taken by the robot. The efficiency of manual separation is low, so the pallets need to be separated by a sheeting device to ensure that only one pallet is taken at a time. Summary of the Invention

[0003] In view of this, the present invention provides a plastic pallet separation method, which enables stacked plastic pallets to be separated automatically compared to the prior art, and improves separation efficiency compared to manual separation.

[0004] To this end, the present invention provides a plastic pallet separating method. First, a separating table body is set up, on which a material picking station and a separating station are set up. Multiple plastic pallet bodies are stacked on the material picking station. A separating mechanism is installed on the separating station. The separating mechanism includes a separating plate and multiple separating suction cups. The separating plate is fixedly installed on the separating station, and multiple separating suction cups are detachably installed on the separating plate. The material picking device is mounted on the separating table body. The material picking device includes a translation mechanism and a lifting mechanism. The translation mechanism includes a slide and a first driving component. The first driving component drives the slide to slide between the material picking station and the separating station. The lifting mechanism includes a lifting plate and a second driving component. The second driving component and the lifting plate are both connected to the slide. The lifting plate performs a lifting action driven by the second driving component. The lifting plate is installed with multiple material picking suction cups facing the plastic pallet body.

[0005] Furthermore, a plurality of protrusions are provided on the plastic pallet body, and the plurality of material-taking suction cups include a plurality of first suction cups and a plurality of second suction cups. The first suction cups are adsorbed on the protrusions, and the second suction cups are adsorbed on the edge of the plastic pallet body.

[0006] Furthermore, a plurality of first waist-shaped holes and a plurality of second waist-shaped holes are provided on the lifting plate, the first suction cup can be detachably installed in the first waist-shaped hole, and the second suction cup can be detachably installed in the second waist-shaped hole.

[0007] Furthermore, the plurality of second waist-shaped holes are respectively opened at two opposite ends of the lifting plate in the width direction, and the plurality of first waist-shaped holes are opened in the middle of the lifting plate.

[0008] Furthermore, positioning components are detachably mounted on both the first waist-shaped hole and the second waist-shaped hole, and both the first suction cup and the second suction cup are positioned in the positioning components.

[0009] Furthermore, the positioning component includes a first nut and a second nut, the first nut abuts against the upper surface of the first waist-shaped hole or the second waist-shaped hole, the second nut abuts against the lower surface of the first waist-shaped hole or the second waist-shaped hole, and the first suction cup and the second suction cup are both screwed between the first nut and the second nut.

[0010] Furthermore, the first suction cup and the second suction cup are both pneumatic suction cups.

[0011] Furthermore, a plurality of third girdle holes are provided on the sheet separation plate, and the sheet separation suction cups are detachably installed in the third girdle holes.

[0012] The present invention provides a method for separating plastic pallets, which mainly includes a separating table body, a separating mechanism, a picking device and a plastic pallet body. The separating table body is provided with a picking station and a separating station. A plurality of plastic pallet bodies are stacked on the picking station. The separating mechanism is installed on the separating station. The picking device includes a translation mechanism and a lifting mechanism. The translation mechanism includes a slide and a first driving component. The first driving component drives the slide to slide between the picking station and the separating station. The lifting mechanism includes a lifting plate and a second driving component. The second driving component and the lifting plate are both connected to the slide. The lifting plate performs a lifting action driven by the second driving component. A plurality of picking suction cups facing the plastic pallet body are installed on the lifting plate. In short, the plastic pallet body on the picking station is adsorbed on the lifting mechanism. The lowering plate is controlled by the picking device and moves to the separating mechanism. In order to ensure that the number of plastic pallet bodies is one after leaving the separating mechanism, the lifting plate will repeat the lifting and lowering five times after adsorbing the plastic pallet bodies through the picking suction cups on it, and make the first control on the number of adsorbed plastic pallet bodies to keep the number in the range of one to two. The plastic pallet bodies are then moved to the separating plate, and multiple separating suction cups are installed on the separating plate. The separating suction cups adsorb the lower surface of the plastic pallet body. If there are two overlapping plastic pallet bodies, the lower plastic pallet body will be adsorbed and separated by the separating suction cups.

[0022] The present invention provides a method for separating plastic pallets, which mainly includes a separating table body, a separating mechanism, a picking device and a plastic pallet body. The separating table body is provided with a picking station and a separating station. A plurality of plastic pallet bodies are stacked on the picking station.
