Description

Carton blank charging equipment

Technical Field

The invention relates to the technical field of packaging equipment, in particular to a paper box blank feeding device.

Background

Cartons are common materials used for packaging. The carton is adaptable to a wide variety of packaging, and paper has the best prospects as a material that can be recycled and reused for a long time in the future. In order to save the storage space of the paper box and facilitate batch production and sale, the existing paper box is made into an expanded structure or a folding structure, and the two structures are both sheet-shaped blanks which need to be processed into the paper box. One of the most common carton packaging types is the spigot-and-bottom type, and the finished carton is a flattened double-layer blank that needs to be pulled apart to form a rectangular parallelepiped before the capping operation can be performed. The most common form of carton packaging used in the pharmaceutical industry is the above-described spigot-and-bottom type. After the paper box blanks are produced, a plurality of blanks are arranged in a row in a paper box, and because the paper box used in the pharmaceutical industry is small and light and the number of the paper boxes required by pharmaceutical manufacturers is large, a plurality of rows of paper box blanks are arranged in one paper box, and the paper box blanks are arranged in a plurality of rows and layers. In order to distinguish the number of cartons, prevent the cartons from scattering during transportation, and reduce the cost, existing carton blank manufacturers have used a strip of paper to roll up a row of carton blanks. Referring to fig. 1, in this way, a long paper sheet 2 is firstly placed below, then a row of paper box blanks 1 is placed on the paper sheet 2, and then both sides of the paper sheet 2 are folded above the paper box blanks 1, so that some manufacturers can stick both sides of the paper sheet 2 above the paper box blanks 1, and some manufacturers cannot but do not influence the functions of distinguishing and counting the paper sheets.

The forming equipment of the paper box is to fold and stick the unfolded paper box blank to form or pull the folded paper box blank to form. Existing carton forming apparatus all have a feeding device, but the feeding device has only a conveying device, such as a conveyor belt. The feeding of the carton blanks requires manual work, and the operator first unrolls the sheet of paper that encloses a row of carton blanks and then places the row of carton blanks on a conveyor. Because the carton blanks are sheet-like and are laid closely adjacent one another in a row within the carton, it is also difficult for the holding device to insert into or between the sides of a row of carton blanks to remove the carton blanks. And because the existence of the wrapping paper sheet, the automatic feeding of the paper box blank is realized, and the paper sheet needs to be taken out firstly. Because the middle part of the paper sheet is positioned below the paper box blanks, one side of the paper sheet is directly pulled to take out the paper sheet, so that a row of paper box blanks can be scattered. Therefore, there is a great difficulty in achieving automatic feeding of carton blanks.

Chinese utility model patent CN207258093U (published as 2018, 04/20) discloses a carton feeding device of a boxing machine, which comprises a workbench, a carton conveying mechanism, a carton blank sheet conveying mechanism and a carton forming mechanism, wherein the carton conveying mechanism is arranged at the center of the workbench, a feeding station is arranged on the workbench, and the carton conveying mechanism rotates around the center of the workbench and obtains a new carton from the feeding station; the paper box forming mechanism is arranged corresponding to the feeding station; the carton forming mechanism comprises a suction box assembly and a forming end plate, and the suction box assembly is arranged on the workbench and used for sucking out carton blank sheets from the carton blank sheet conveying mechanism; the forming end plate is arranged between the box suction assembly and the feeding station and used for pressing the paper box blank sheets to be opened when the box suction assembly sucks the paper box blank sheets out. This patent discloses a carton blank transport mechanism including a pusher and a guide rail, but still requires a manual operation to place a row of carton blanks on the guide rail, and the pusher pushes the carton blanks forward for transport.

Chinese utility model patent CN207844567U (published as 2018, 09 and 11) discloses a feeding mechanism applied to a carton pasting assembly line, including: a frame; a discharge table; a first power source mounted on the frame; and, the feeding agencies of assembly in the frame, feeding agencies include: the assembling seat, the material taking arm, the second power source and the vacuum pump are arranged on the assembling seat; the end part of the material taking arm is provided with a sucking disc. Decorative paper is placed on the blowing bench, at the in-process that shifts the conveyer belt with decorative paper, the arm downstream is got in the drive of second power supply, the evacuation pump is bled and is made the sucking disc adsorb the decorative paper, later the arm upward movement of decorative paper is taken in the drive of second power supply drive, third power supply drive mount pad rotates to make the arm of getting remove the top of conveyer belt, the arm is got in the drive of second power supply transfer, the sucking disc stops breathing in, decorative paper falls in the conveyer belt. The patent discloses a pick arm and suction cups, but the patent draws the feed from the pick table one by one, and in use, it still requires a manual operation to pick a row of carton blanks from the magazine and place them on the discharge table, and cannot achieve the purpose of picking the carton blanks from the magazine and removing the wrapped paper sheets.
