Technical Field

The invention relates to the field of cigarette sorting, in particular to a sorting device for improving sorting speed of special-shaped cigarettes and a control method thereof.

Background

At present in the internal cigarette sorting field, the semi-automatic cigarette sorting system that adopts only is applicable to standard specification cigarette sorting, can't compromise the letter sorting of heterotypic specification cigarette, leads to the letter sorting of heterotypic specification cigarette to adopt manual sorting or electronic tags to sort, sorts inefficiency, and the error rate is high, and intensity of labour is big.

The invention discloses a Chinese patent with an authorization publication number of CN106043834B and a control method thereof, which comprises a cigarette bin, a special-shaped cigarette discharging mechanism, a special-shaped cigarette conveying mechanism, a cigarette posture adjusting mechanism, a marking mechanism and a sorting and packaging mechanism, wherein in order to adjust cigarette postures and improve the success rate of marking, two groups of steering belts and the cigarette posture adjusting mechanism are used for realizing the edge-leaning arrangement of cigarettes, and the invention has the defects that: after the cigarette carton is turned for the first time, the length direction of the cigarette carton is consistent with the conveying direction, the length of the cigarette carton is generally 2-4 times of the width of the cigarette carton, and after the cigarette carton is turned, the length of a belt occupied by each cigarette carton is too long, so that the utilization rate of the belt is very low, and the sorting speed of special-shaped cigarettes is influenced.

Disclosure of Invention

In order to solve the problem that the sorting speed is influenced by the low utilization rate of a conveying belt of the existing special-shaped cigarette sorting system in the background technology, the invention provides the sorting device for improving the sorting speed of the special-shaped cigarettes, and the device cancels the steering of the special-shaped cigarettes by a smoke-removing posture adjusting mechanism, so that the length direction of the cigarettes is vertical to the conveying direction, the utilization rate of the belt is improved, and the sorting speed is improved; secondly, adjust the middle part of conveyer belt through correcting unit with heterotypic cigarette to guarantee that heterotypic cigarette is when beating the sign indicating number device, the position of bar code aligns with the position of beating the sign indicating number laser head, thereby improve letter sorting speed on the basis that does not influence the success rate of beating the sign indicating number, specific technical scheme as follows.

The utility model provides an improve sorting device of abnormal shape cigarette letter sorting speed, includes main conveyor belt and beats sign indicating number device, its characterized in that: the code printing device is directly connected with the tail end of the main conveying belt; and a first height limiting rod and a second height limiting rod are arranged on two sides of the main conveying belt and used for adjusting the special-shaped cigarettes to the middle of the main conveying belt.

Therefore, the structure cancels a steering belt in the existing abnormal cigarette sorting system and a cigarette posture adjusting mechanism for arranging the side of the abnormal cigarette, thereby canceling the steering of the abnormal cigarette and enabling the length direction of the strip cigarette to be vertical to the conveying direction all the time. Compared with the prior art, the cigarette carton conveying mode has the advantages that the cigarette carton interval can be set to be shorter (enough steering distance needs to be reserved in the prior art), so that the utilization rate of a belt is improved, and the sorting speed is increased; secondly, through first limit for height pole and second limit for height pole, can adjust the middle part to main conveyer belt with heterotypic cigarette on the main conveyer belt to guarantee that heterotypic cigarette is when beating sign indicating number device, the position of bar code aligns with the position of beating sign indicating number laser head, thereby improves letter sorting speed on the basis that does not influence the success rate of beating the sign indicating number. The code printing device is the prior art, and for example, a marking mechanism in 'a special-shaped cigarette sorting system and a control method thereof' disclosed in the Chinese patent with the authorization publication number of CN106043834B can be used.

The standard cigarette is defined as a cigarette with a length, width and height specification of 27 x 8 x 5cm (deviation range +/-10%), and the special-shaped cigarette is defined as other cigarettes without the specification. Among these special-shaped cigarettes, the special-shaped cigarette with the length, width and height specifications of 27 × 8 × 2.4cm (deviation range ± 10%) or 27 × 7 × 5cm (deviation range ± 10%) is defined as a common special-shaped cigarette, and the other special-shaped cigarettes other than this specification are defined as special-shaped cigarettes, and the common specifications of the special-shaped cigarettes are 17 × 11 × 8cm, 23 × 14.5 cm and 32 × 8 × 2.4 cm. Because the special-shaped cigarette (generally a square cigarette) is thicker than the common special-shaped cigarette, the first limit height is set to adjust the cigarette posture of the special-shaped cigarette and filter the common special-shaped cigarette which is thinner than the special-shaped cigarette, thereby finishing the correction of the cigarette posture of the special-shaped cigarette. Specifically, the height limit height of the first height limit rod is 6 cm.
