Description

Technical field:

[0001] The utility model relates to the technical field of industrial automation, and in particular to a rectangular tray automatic straightening device and a tray splitting and stacking device, which can quickly straighten square trays commonly used in industrial production and can split a plurality of stacked trays one by one to avoid displacement of materials in the trays. Background technology:

[0002] For smaller industrial parts, such as circuit boards or thermal printing sheets, the main body surface is equipped with components and related circuits. During transportation, the surface needs to be protected to avoid scratches or bumps. In large-scale industrial production, the number and variety of products circulated each time are large, so such products need to be neatly loaded and stacked before being sent to the next process. In order to meet the stacking requirements, the pallets used to support small-sized materials are generally cone-shaped. Empty pallets can be stacked one by one into a group. When in use, the empty pallets are divided into trays for loading. After loading, the full pallets still need to be stacked and stacked. At this time, the posture of the pallet needs to be guaranteed to avoid the tilt of the full pallet causing the small-sized materials inside to shift or slide. Summary of the invention:

[0003] In view of the shortcomings and deficiencies in the prior art, the utility model proposes a rectangular tray automatic straightening device and a tray splitting and stacking device which can separate a plurality of stacked trays one by one and automatically straighten the posture of the trays supporting materials to avoid displacement of the materials in the trays.

[0004] The utility model achieves this through the following measures:

[0005] A rectangular tray automatic straightening device is provided with a bottom plate, characterized in that a rectangular tray through hole is provided on the bottom plate to facilitate the passage of the tray, and more than two straightening vertical plates are arranged around the tray through hole on the bottom plate, the straightening vertical plates are arranged in pairs on the outside of the four top corners of the tray through hole, the angle between the two straightening vertical plates arranged on the outside of the same top corner is 90 degrees, and there is a gap between the two straightening vertical plates.

[0006] The upper end of the straightening vertical plate of the utility model is provided with an outwardly inclined section, the outwardly inclined angle of the outwardly inclined section does not exceed 45 degrees, and more than two straightening vertical plates form a funnel-shaped straightening channel around the through hole of the tray.

[0007] The utility model also proposes a tray dividing and stacking device, which is characterized in that it is provided with the automatic straightening device for the rectangular tray as described above, and the tray through hole is also provided with an adsorption assembly and a limit assembly located below the tray through hole, the adsorption assembly includes an adsorption cylinder, an adsorption bracket and a negative pressure suction cup arranged on the adsorption bracket, the adsorption cylinder drives the adsorption bracket to be lifted along the tray through hole below the bottom plate to above the bottom plate, and the negative pressure suction cup on the adsorption bracket is used to complete the grabbing of the tray located at the bottom.

[0008] The utility model further provides two groups of adsorption components symmetrically arranged at the through holes of the tray.

[0009] The limit assembly of the utility model is provided with a limit plate which moves into the through hole of the tray along one side thereof. The limit plate is used to be inserted between two stacked trays so as to facilitate the empty tray at the bottom to be separated smoothly from the upper tray under the action of the adsorption assembly. The limit plate is driven by the limit clamping cylinder.

[0010] Furthermore, the utility model provides at least one sheet-shaped insertion portion on one side of the limit plate close to the through hole of the tray, so as to facilitate insertion between two stacked material trays. Furthermore, two limit plates are symmetrically provided on both sides of the through hole of the tray, and the two limit plates are driven by the same limit clamping cylinder to complete the action of moving away from / approaching the through hole of the tray.

[0011] When performing the tray separation operation, the utility model stacks multiple empty trays above the bottom plate. At this time, the multiple empty trays are supported by two limit plates in the limit assembly. The adsorption assembly is opened, and the adsorption cylinder drives the adsorption bracket to lift the empty tray upward from the bottom of the bottom plate, and the negative pressure suction cup on the adsorption bracket is attracted to the bottom surface of the lowest empty tray. The limit assembly is opened to make the limit plate move away from the tray through hole, and the adsorption bracket is driven to move downward by the adsorption cylinder to pull the lowest empty tray from the multi-layer stacked trays to the bottom of the bottom plate. The limit assembly is closed, and the limit plate moves toward the tray through hole to support the multiple empty trays that are aligned and fall down by the alignment vertical plate under the action of gravity. When performing the full pallet stacking operation, the full pallet is sent to the bottom of the bottom plate and is located directly below the pallet through-hole on the bottom plate. The bottom surface of the pallet is adsorbed by the adsorption assembly located below the pallet through-hole, and the adsorption cylinder drives the adsorption bracket and the negative pressure suction cup on the adsorption bracket. After the pallet is lifted from below the bottom plate along the pallet through-hole to above the bottom plate, the adsorption assembly is retracted. When the full pallet rises to the upper side of the bottom plate through the pallet through-hole, the limit assembly on the bottom plate opens, so that the full pallet can be smoothly lifted to the funnel-shaped straightening channel composed of multiple straightening vertical plates. Thereafter, the limit assembly closes, and the full pallet gradually falls along the funnel-shaped straightening channel under the action of gravity and is aligned on the upper side of the limit plate.

[0012] Compared with the prior art, the present invention can separate pallets for loading small-sized parts one by one and stably stack full pallets, and can automatically adjust the posture of the pallet supporting the material to avoid shifting of the material in the pallet, thereby improving production efficiency and quality management level, reducing manual intervention and improving production efficiency.

The limiting plate 9 is driven by the limiting clamping cylinder 10.

[0023] Furthermore, the utility model provides at least one sheet-shaped insertion portion on the side of the limiting plate 9 close to the tray through hole 3, so as to facilitate insertion between two stacked material trays 2.
