Automatic overturning, staggering and stacking device for carton packaging

Abstract

The invention relates to an automatic overturning, staggering and stacking device for carton packaging. An overturning mechanism is used for overturning the paperboards on a first conveying belt by 180 degrees and then transferring the paperboards to a second conveying belt, a flapping mechanism comprises two flapping plates which are oppositely arranged, and the two flapping plates are located atthe two sides of a third conveying belt and are in transmission connection with a roller shaft of the third transmission roller so as to do the horizontal reciprocating motion to get close to or getaway from the third conveying belt. A limiting mechanism is located at the discharging side of the third conveying belt and comprises a front limiting plate and a rear limiting plate, the rear limiting plate is installed on a lifting base, the front limiting plate can be installed on the rear limiting plate in an up-down sliding manner, and the front limiting plate and the rear limiting plate areboth located on the movement stroke of the third conveying belt and are driven by a same power device to act. According to the automatic overturning, staggering and stacking device, the maximum stacking thickness of the paperboards is increased, the transfer frequency of the stacked paperboards can be reduced, the staggered stacking of the paperboards is achieved, the warping deformation of the paperboards can be prevented, and the automatic overturning, staggering and stacking device is high in automation degree and stability.

Description

technical field [0001] The invention relates to the field of auxiliary tooling for carton processing, in particular to a cardboard stacking device for carton packaging. Background technique [0002] Cardboard is the main material for making packaging boxes or crates. After the production and processing of cardboard is completed, in order to facilitate handling and storage, the cardboard needs to be stacked. Most of the existing methods are stacking by manual operation, which is labor-intensive, has high labor costs, and the stacking efficiency is not ideal. In addition, cardboard is mostly sold in stacks of 15 or 20 sheets. High stacks must be recounted by workers, which is labor-intensive and inefficient. [0003] The invention patent with the patent number of 201510692650.1 discloses a cardboard automatic stacking device, which pushes the cardboard to the retaining wall through the push plate during the cardboard conveying process, and transports the cardboard to the sort...

AI Technical Summary

Problems solved by technology

This device has the following defects: (1) the first bracket is driven up and down by the first bracket cylinder, and the cardboard is continuously stacked on the first bracket

Because the cylinder of the first bracket occupies a certain space, a certain height difference is formed between the first bracket and the ground, which makes the transfer of the cardboard stack inconvenient

(2) The device cannot realize the automatic flipping of the cardboard. After the cardboard is transferred to the second bracket, in order to prevent the cardboard from warping and deformation, it is necessary to manually turn the cardboard in batches, which brings a certain workload to the staff. At the same time, the orderly state of the cardboard pile is also broken

(3) The maximum stacking thickness of the device is limited by the maximum telescopic length of the first bracket cylinder. If the piston rod of the first bracket cylinder is too long, it will cause inconvenient transfer of the cardboard pile. If it is too short, the thickness of a single stack is limited. , requires the staff to frequently transfer the cardboard pile, increasing the workload of the staff
