Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to a device for loading tobacco stacks into boxes and folding them into shape. Background Technology

[0002] Currently, the cigarettes produced by the packaging machine need to be transported one by one to the boxing area via an overhead conveyor line to complete the subsequent boxing and sealing processes.

[0003] This process involves packing cigarette stacks into cartons and folding numerous inner and outer layers of the cartons. Manual assistance is required to retrieve carton blanks from the carton warehouse, unfold them into cartons, push the cigarette stacks into the cartons, and then manually close the openings on both sides of the carton. This manual operation is inefficient and wastes significant human and material resources. A cigarette factory's economic benefits depend on its production volume; therefore, production efficiency is crucial. Manual packing is technically low-skilled and time-consuming. The market needs an automated cigarette stack loading and folding device to replace manual packing and folding processes and improve production efficiency. Utility Model Content

The stacking station 91 is used to supply cigarette stacks, and the storage station 93 is used to supply box blanks. The boxing station 92 is located between the stacking station 91 and the storage station 93, and is used to receive the cartons and cigarette stacks unfolded from the box blanks, serving as the collection point for the cartons and cigarette stacks.

[0052] The box suction mechanism 10 is located between the packing station 92 and the storage station 93. The box suction mechanism 10 is used to unfold the box blank supplied by the storage station 93 into a carton and position the carton to the packing station 92.

[0053] The cigarette stack feeding mechanism 20 is located between the pushing station 91 and the packing station 92. The cigarette stack feeding mechanism 20 is used to push the cigarette stacks supplied by the pushing station 91 into the carton positioned in the packing station 92.

[0054] The bottom forming mechanism 30 of the carton is located at the bottom of the packing station 92, and the top forming mechanism 40 of the carton is located at the top of the packing station 92, for closing and forming the openings on both sides of the carton.

[0055] Specifically, the suction box mechanism 10 includes a box-dragging assembly 11 and a suction assembly 12.

[0057] The adsorption assembly 12 includes suction cup mounting plates 121, two of which are vertically fixed to both ends of the movable plate of the trolley. Several vacuum suction cups 122 are arranged on the side of the suction cup mounting plates 121 facing the storage station 93. An air distribution channel is formed inside the suction cup mounting plates 121, one end of which is connected to the vacuum suction cups 122, and the other end is connected to a negative pressure device via an air pipe. The box blank is adsorbed or released by the multiple sets of vacuum suction cups 122.

[0058] A cable chain is also connected to the bottom plate 111 of the trailer. The cable chain is responsible for guiding and restraining the air pipes, cables and other wiring harnesses during the movement of the trailer sliding plate 112.

[0059] The carton bottom forming mechanism 30 of this embodiment includes a forming plate 31, which is disposed between the material storage station 93 and the carton packing station 92. The forming plate 31 has a supporting end 311 and a forming end 312 at its two ends. The forming end 312 is disposed on one side of the material storage station 93 and has an arc-shaped guide surface. The arc-shaped guide surface is used to squeeze the carton blank to unfold it into a carton. The supporting end 311 is disposed at the bottom of the carton packing station 92 and is used to support the unfolded carton.

[0060] In use, multiple sets of vacuum suction cups 122 extend from both sides of the forming plate 31, adsorbing the upper side of the box blank; the box-pulling assembly 11 drives the adsorption assembly 12 to move horizontally from the storage station 93 to the packing station 92. The multiple sets of vacuum suction cups 122 adsorb the box blank and drag it from the forming end 312 of the forming plate 31 to the supporting end 311. The lower side of the box blank is squeezed by the arc-shaped guide surface, changing from vertical to horizontal, so that the box blank unfolds into a carton; after the box-pulling assembly 11 drives the adsorption assembly 12 to the position, the unfolded carton is exactly in the packing station 92. In this way, the carton preparation is completed, waiting for the cigarette stacks to be put into the box.

The upper folding plate 43 is hinged to the top folding mounting frame 41 via a pivot. The upper folding drive 44 is connected to the upper folding plate 43 in a transmission manner. The upper folding drive 44 drives the upper folding plate 43 to flip, thereby folding the top of the carton.

[0079] There are two upper folding plates 43 and two upper folding drive components 44. The two upper folding plates 43 and the two upper folding drive components 44 are respectively set at both ends of the top folding mounting frame 41 to realize the folding and forming of the upper carton pages on both sides of the carton.

[0080] The top folding mounting bracket 41 is also provided with an upper guide plate 45, which provides a guiding function for the carton.

[0081] Based on the above mechanisms, the cigarette stack loading and folding forming device of this embodiment is provided with a suction mechanism 10, a cigarette stack loading mechanism 20, a carton bottom forming mechanism 30, and a carton top forming mechanism 40 on the main frame. Each mechanism is independently fixed on the main frame. The suction mechanism 10 grabs the first carton blank in the carton warehouse set on the material storage station 93 and moves it to the packing station 92. During the transfer of the carton blank, the carton bottom forming mechanism 30 guides the carton blank and unfolds it to form a cigarette stack filling space. The cigarette stack loading mechanism 20 is responsible for pushing the cigarette stack from the stacking station 91 into the carton, widening the carton pages on the packing side, and supporting the cigarette stack. The carton bottom forming mechanism 30 is responsible for providing folding forming function for the inner pages and the lower outer pages of the carton at the bottom of the carton after the cigarette stack enters the carton. The carton top forming mechanism 40 provides folding forming function for the upper outer page of the carton after the carton bottom forming mechanism 30 completes the carton page closing process. This process is repeated to automate the box-packing and sealing process, replacing manual box packing and folding, and improving production efficiency.
