Background

The cigarette product packaging specification is generally divided into a carton packaging unit containing ten cigarette packets of cigarette products, which is divided into an upper layer and a lower layer, wherein each layer contains five packets, and the packaging patterns of the cigarette packets are consistent. In order to meet the requirements of products and users and improve the package beautifying effect, the package patterns of five cigarette packets need to be designed in a series mode, the package patterns of the five cigarette packets are different, and then the five cigarette packet cigarette products with different patterns are arranged in sequence to form a complete continuous pattern together. The existing cigarette production and packaging processes are generally as follows: the cigarette is packed from the tray unloader to the hard box packing machine, then enters the outer transparent paper packing machine of box through the cigarette packet conveying channel for transparent package, then enters the hard strip packing machine for packing, then enters the outer transparent paper packing machine of strip for packing and the like, and because the pattern of each cigarette packet is the same, the existing production equipment can not meet the requirement of simultaneously producing the cigarette packets with various different patterns and arranging the cigarette packets with different patterns in sequence.

And a discharging detection device is fixedly arranged on the arrangement transmission line 3 and used for detecting whether the arranged cigarette packets meet the requirements or not.

During operation, tobacco bale gets into universal sorting device 1 from pay-off transmission line 4. When the cigarette packet moves on the feeding conveying line 4, the feeding detection device positioned on the feeding conveying line 4 detects the cigarette packet, and the detection mainly comprises two parts, namely, whether the cigarette packet is qualified or not is detected, and whether the cigarette packet is damaged or not is detected; the other part is to detect which type of cigarette packet it belongs to. The cigarette strip produced by the embodiment forms a complete pattern by 5 cigarette packets, so that 5 types of patterns exist and respectively correspond to the warehouse bodies 20 from 1# to 5 #. When unqualified tobacco bales are detected, the tobacco bales are removed when passing through an unqualified product removing device. Qualified cigarette packets enter the universal sorting device 1.

After the cigarette packet 5 enters the universal sorting device 1, the system determines which type of pattern the cigarette packet belongs to according to the data obtained by the feeding detection device, and sends the cigarette packet into the corresponding 1# -5 # warehouse body 20. The conveying method comprises the following steps:

determining the type of the pattern on the cigarette packet, starting a preset travelling path according to the type of the pattern of the cigarette packet: the universal wheels parallel to the matching warehouse body rotate linearly, that is, the included angle between the rotating direction of the rotating wheel 124 and the matching warehouse body is 0 °. The included angles between the rotation angles of the other universal wheels which are not parallel to the matching warehouse body and the matching warehouse body are 45-90 degrees, as shown in fig. 14 and 15, and in the figures, the arrow direction is the rotation direction of the rotating wheel. Taking fig. 14 as an example, when cigarette packets 5 are determined to be sent into the 1# warehouse, all the rotating wheels in the universal wheels (area a) of the universal sorting device 1 parallel to the 1# warehouse rotate from left to right, and the rotating direction of the rotating wheels forms an angle of 0 degree with the 1# warehouse. All the rotating wheels in the front half part (area B) of the universal sorting device 1 rotate towards the lower right, and the purpose of the arrangement is to feed cigarette packets 5 into the area A through oblique movement if the cigarette packets are in the area B. All the rotating wheels in the rear half part (area C) of the universal sorting device 1 rotate rightwards, so that the purpose of feeding the cigarette packet 5 into the area A can be achieved, and the cigarette packet moving in the area A can be prevented from deviating from the straight running track.

Similarly, if a packet 5 of cigarettes is determined to be fed into the 3# magazine, all the wheels parallel to the 3# magazine (zone a) are turned from left to right, with the direction of rotation being at an angle of 0 ° to the 3# magazine. All the rotating wheels in the area B of the front half part on the left side of the universal sorting device 1 rotate from the lower right; all the rotating wheels in the area B' of the front half part at the right side of the universal sorting device 1 rotate from the left upper part; all the rotating wheels in the area C on the rear half part on the left side of the universal sorting device 1 rotate downwards; all the rotating wheels in the area of the rear half C' on the right side of the universal sorting device 1 rotate upwards.

After the cigarette packets 5 are sent into the matched warehouse body 20, the cigarette packet in-place sensor 202 detects a signal, and the system controls the lifting cylinder 200 to contract downwards by the height of one cigarette packet, so that the cigarette packets 5 are stored in the warehouse and cached. After each cigarette pack is stored in each magazine 20, the arrangement is started. During arrangement, the cigarette packets 5 are arranged above the corresponding warehouse body 20 in sequence, if a cigarette packet lack is found, the lifting cylinder 200 in the corresponding warehouse body 20 is pushed upwards, one cigarette packet is pushed out to form a row of 5 cigarette packets with the rest cigarette packets to form a complete pattern, and then the material pushing cylinder 203 pushes the 5 cigarette packets towards the arrangement conveying line 3 and sends the 5 cigarette packets to the arrangement conveying line 3. The transmission line 3 is arranged to move rightwards and enter the next packaging link.

The above embodiment merely describes the simplest control manner of the universal sorting apparatus 1, and it can be extended on the basis of this embodiment, for example, a sensor for detecting the current state and position of the cigarette packet 5 is provided on the universal sorting apparatus 1. If a camera is arranged above the universal sorting device 1, after the position of the cigarette packet 5 is known through the camera, the rotating wheels on the position where the controller is located and the route to be traveled rotate according to requirements, and the rest rotating wheels are not moved or respond to the motion requirements of the rest cigarette packets. Such control enables "batch, serial, customized transport", that is, a plurality of packets of cigarettes, of the same or different types, can be simultaneously sorted and transported on one universal sorting device 1 and finally fed into a designated area.
