Description

Technical Field

[0001] The present invention relates to the technical field of packing boxes, and particularly relates to a packing box loading device and an unpacking system. Background Art

[0002] All kinds of cartons used for logistics packaging are generally in the form of cardboard when they come in, that is, in a flat structure, without being opened and folded into a three-dimensional structure; and generally, multiple layers of cardboard are bundled together with tie straps (flat nylon straps or PE straps) for easy transportation of the cardboard; generally, there are 10 sheets per bundle. Therefore, when in use, the tie straps generally need to be cut off, and then the single cardboard is opened and folded into a three-dimensional carton. In the initial stage, generally, the tie straps were manually cut and removed, and then each cardboard was manually opened and folded into a carton. With the development of the production economy, the method of manually opening the cardboard and folding it into a carton can no longer meet the production needs. Thus, automatic unpacking machines began to appear on the market, with an unpacking speed of about 5 - 10 cartons per minute. However, the operations of cutting the tie straps of the bundled cardboard incoming materials and loading the cardboard are still carried out manually; so one or two workers need to be matched before each unpacking machine feeds. If working in two shifts, two to four workers are required for matching. Although it can ensure the normal operation of the unpacking machine, the labor cost is relatively high.

[0003] In recent years, with the in-depth development and application of production automation, the unpacking machines with an unpacking speed of 5 - 10 cartons per minute can basically no longer meet the packaging requirements of the industry. The market has started to develop high-speed horizontal unpacking machines, with an unpacking speed that can reach 30 - 40 cartons per minute; at the same time, auxiliary equipment such as tape cutting equipment, robotic palletizers, and automatic loading machines are used to achieve the combined loading of cardboard. Although this unpacking process can effectively replace the manual loading method and improve the loading speed of the cardboard, there are still the following problems: 1. The tape cutting equipment generally can only complete the tape cutting operation of the packing tape, and the cut packing tape still needs to be manually assisted to be pulled out; moreover, the tape cutting component and the tape hooking component in the existing tape cutting equipment are generally located in the same component. The tape hooking component is mainly used for hooking up the packing tape before cutting, and the cut packing tape is prone to loosening or displacement, which is not conducive to the extraction of the packing tape; 2. The loading speed of the cardboard is limited by the cooperation between each independent functional equipment. Although the loading speed has been improved compared with manual loading, it still cannot meet the production capacity requirements of the automatic unpacking equipment, and the loading speed still needs to be further improved; 3. The introduction of a variety of automated equipment not only greatly increases the equipment cost, but also the assembled production line often requires a large production space; at the same time, the difficulty in equipment manufacturing, transportation, debugging, and maintenance is also increased.

[0004] In summary, researching a technology that can replace manual feeding, reduce labor costs and the difficulty of manual operation, and improve packaging efficiency is of great significance for accelerating the production capacity of various industries and promoting the development of various industries.

[0058] When the side of the packaging tape to be cut adjacent to the tape cutting assembly 250 is pulled by the first tape pulling component 260a and the second tape pulling component 260b to be closely attached to the side of the paper skin, the tape cutting drive module 2521 is turned on, driving the tape cutting unit 251 to move along the tape cutting slide rail slider group 2522 to a position corresponding to the packaging tape; subsequently, the tape cutting drive sub-module 2511 is turned on, driving the tape cutting module 2512 arranged on the driving end of the tape cutting drive sub-module 2511 to pass through the tape cutting slot 2312 of the first push plate 231; then the tape cutting module 2512 is turned on to cut the packaging tape. After the cutting is completed, the tape cutting module 2512 is turned off, and the tape cutting drive sub-module 2511 is started again to drive the tape cutting module 2512 to reset.

[0059] Please further refer to the attached Figure 2 In some embodiments, the tape cutting mechanism 200 further includes a discharge component 270 for discharging the cut packaging tape; preferably, the discharge component 270 is arranged at a preset position, for example: the preset position is between the first tape pulling component 260a and the second tape pulling component 260b.
