The box conveying line 1, the handle screening mechanism 2, the handle inner arch mechanism 3, the handle transfer device 4 and the assembling mechanism 5 in the packaging box assembling device are correspondingly provided with sensors according to actual needs to detect positions of related parts such as handles and boxes, the sensors can be in the form of sensors commonly used in the prior art such as photoelectric switches and travel switches, the configuration modes of the related sensors described in related patents in the background art can be referred to, the configuration modes of the related sensors in the technical scheme disclosed in Chinese patent number 2017204769657 can be referred to, and the packaging box assembling device in the embodiment does not limit the specific structural form and the mounting position of the sensors. In addition, the devices and the transfer devices related to the handle inner arch disclosed in chinese patent nos. 201520506435.3, 201520506647.1 and 201520506776.0 are adopted for the handle inner arch mechanism 3 and the handle transfer device 4, and are not described herein.

The invention also provides an assembling method of the packing box, wherein the packing box comprises a box body and a handle, two inserting holes are formed in the box body, and corresponding ends of the handle are inserted into the corresponding inserting holes; the assembling equipment for assembling the packing box comprises a box conveying line for conveying the box, a handle screening mechanism for screening handles, a handle inner arch mechanism for bending and arching the handles and an assembling mechanism for assembling the handles and the box together, wherein a punching mechanism for punching the box is arranged on the box conveying line; the assembling method comprises a box body processing procedure and an assembling procedure; the box body processing procedure is that in the process of conveying the box body on automatic packaging box assembly equipment, punching treatment is carried out on the box body to form an inserting hole; and the assembling procedure is to insert the corresponding end parts of the handles into the corresponding insertion holes so as to assemble the handles with the box body.

Specifically, the box is in carrying the in-process through the box transfer chain, directly punch the box on line through the mechanism that punches, through the position and the distance that punch of adjustment mechanism, alright guarantee that the box carries to the equipment mechanism department, two cartridge hole positions and the distance that punch on the box and form can with the both ends assorted of handle, compare in prior art the box line and punch under and form the cartridge hole, solve later stage and carry the equipment mechanism department cartridge hole and handle can not be accurate matching and appear the handle and insert the problem that causes the box damage outside the cartridge hole. Under the condition that the lifting handle is installed by adopting a reinforcing plate configured by the box body, a folding reinforcing plate is arranged on the shaking cover of the box body, and a turnover mechanism for bending the reinforcing plate is further configured on the box body conveying line; the box body processing procedure specifically comprises the following steps: in the conveying process of the box body, before punching the box body, the reinforcing plate is folded so that the reinforcing plate is attached to the surface of the shake cover, and then the shake cover and the reinforcing plate are punched together to form the inserting hole. Specifically, the box reaches the mechanism department of turning over earlier in the transportation process, turns over the mechanism through turning over and carries out the upset operation to the reinforcing plate to make the reinforcing plate paste and lean on the surface of shaking the lid, then, the box continues to remove the mechanism department of punching, simultaneously together punch processing to shaking the lid and reinforcing plate through the mechanism of punching. Preferably, after the reinforcing plate is attached to the surface of the shake cover, in the continuous conveying process through the box conveying line, the reinforcing plate is attached to the shake cover surface all the time and finally moves to the assembly mechanism, so that on one hand, the position of a hole on the reinforcing plate is kept consistent with that of a plug-in hole on the shake cover, and on the other hand, the phenomenon that the reinforcing plate is automatically turned over and opened to influence the normal conveying of the box due to the influence of bending stress is avoided. The box body is in a folded state in the conveying process, and the whole box body is flat, so that the swing cover on the box body is divided into an upper layer and a lower layer, the upper layer comprises an inner swing cover with a reinforcing plate and a side swing cover, and the lower layer comprises a rear swing cover and a side swing cover; the box processing procedure also comprises the following steps: in the conveying process of the box body, before the reinforcing plate is folded, the upper layer shaking cover and the lower layer shaking cover of the box body are separated, and then the separated reinforcing plate positioned on the upper layer shaking cover is folded.

Referring to fig. 19, the processing procedure of the box body is described, where the box body 1000 is in a folded state and is placed on a box body conveying line for conveying, at this time, an inner swing cover 1001 and one side swing cover 1003 in the box body 1000 are located at an upper layer, an outer swing cover 1002 and the other side swing cover 1003 are located at a lower layer, the inner swing cover 1001 abuts against the outer swing cover 1002 and the side swing cover 1003 located at the lower layer for conveying, the box body 1000 is conveyed forward along with the box body conveying line to the separation guiding mechanism, the upper swing cover and the lower swing cover are separated from each other through the separation guiding mechanism, after the upper swing cover and the lower swing cover are separated, the box body moves to the folding mechanism along with the box body conveying line, the folding mechanism folds a reinforcing plate 10011 on the upper swing cover 1001, and as shown in fig. 20, the reinforcing plate 10011 abuts against the lower surface of the inner swing cover 1001 after the folding mechanism. The box conveyor line drives the box to continue moving, so that the box moves to the punching mechanism, as shown in fig. 21, and the punching mechanism punches the inner swing cover 1001 and the reinforcing plate 10011 together to form the inserting hole 10012.

In addition, the assembly method specifically further comprises the following steps: a handle supplying step; and the hand supply procedure is used for conveying the handles to the position above the box body positioned at the assembly station. Specifically, a plurality of handles are picked up firstly, then, the picked handles are screened to obtain handles with correct postures, and finally, the handles with correct postures are conveyed to the upper part of the box body positioned at the assembly station.
