Description

Technical Field

[0001] This utility model relates to a flexible box double-station box supporting device, belonging to the field of automated logistics conveying and sorting technology. Background Technology

[0002] Currently, some cartons of cigarettes in the smart logistics of commercial tobacco use flexible boxes for packaging. Flexible boxes are reusable green packaging boxes that shrink naturally and need to be expanded to the appropriate size according to the shape of the stacked cartons of cigarettes when in use. A typical flexible box is the flexible turnover box for cartons of cigarettes mentioned in Chinese patent publication number CN111470144A.

[0003] In the existing technology, the opening of such elastic boxes is generally accomplished by using a separate special support. This special support usually has only one degree of freedom, namely the vertical stretching direction. However, in practice, this support often causes damage to the box due to over-opening or abnormal opening, resulting in high material and rework costs. Moreover, its position is often relatively fixed, which is not convenient for the integrated operation of opening and packing various sizes of cigarette packs. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a flexible box double-station box supporting device. Based on the setting of lifting unit and box supporting unit, the flexible box can effectively ensure that the flexible box is opened in multiple directions in a manner that conforms to the shape of the box, effectively avoiding over-opening, abnormal opening, etc., and the position is easy to adjust, which can greatly benefit the application of various cigarette packing production lines.

A first guide rail 110 and a second guide rail 11 are respectively provided on the sides of the first toothed chain 104 and the second toothed chain 105. 1. Both ends of the upper and lower structures of the box-support unit 2 are slidably mounted on the first guide rail 110 and the second guide rail 111 via the second connecting block 109; an upper and lower box-support cylinder 211 is fixedly mounted on the lower structure of the box-support unit 2, and the power end of the upper and lower box-support cylinder 211 is connected and mounted on the upper structure of the box-support unit 2; the upper and lower box-support cylinder 211 is mounted at the center point of the plane of the upper structure via the clamp connector 217; a fixing plate 206 is mounted on the top surface of the lower structure of the box-support unit 2; an elastic limiting plate 210 is fixed on the fixing plate 206 at the position directly opposite to the upper and lower structures.

[0019] The second embodiment of this utility model is largely the same as the first embodiment, except that the upper structure of the box support unit 2 is fixed with a first guide rail connector 201 and a third guide rail connector 203 at both ends, and both the first guide rail connector 201 and the third guide rail connector 203 are fixed to the second connecting block 109.

[0020] Furthermore, the upper structure of the box support unit 2 is fixed with a first guide rail connector 201 and a third guide rail connector 203 at both ends, and both the first guide rail connector 201 and the third guide rail connector 203 are fixed to the second connecting block 109.

[0021] The third embodiment of this utility model is largely the same as the first embodiment, except that a left telescopic plate 207 and a right telescopic plate 208 are respectively installed on both sides of the fixing plate 206 of the lower structure of the box support unit 2, and a telescopic cylinder 209 is installed inside the box support unit 2 to push the left telescopic plate 207 and the right telescopic plate 208 to open and close relative to each other.

[0022] Furthermore, the upper structure of the box support unit 2 is equipped with a first cylinder 215 and a second cylinder 216. The first cylinder 215 and the second cylinder 216 are coaxially and fixedly installed in opposite directions.

Thus, the lifting unit 1 is raised and lowered by the forward and reverse rotation of the top servo motor assembly 101, and the box support unit 2 is raised and lowered by the connection between the first connecting block 108 on the lifting unit 1 and the box support unit 2.

[0027] The guide rail connectors 201, 202, 203, and 204 on the box-supporting unit 2 are connected to the first guide rail 110 and the second guide rail 111 of the lifting unit 1 via the second connecting block 109, thus achieving the lifting and guiding of the box-supporting unit 2. The box-supporting unit 2 has two box-supporting stations, consisting of an upper clamp and a lower clamp. After the upper and lower clamps retract left and right, and up and down, they meet the box-supporting conditions, allowing other stations to retrieve and support the box. The lower clamp has a fixed plate 206, with a left telescopic plate 207 and a right telescopic plate 208 on its sides. The left telescopic plate 207 and the right telescopic plate 208 are respectively installed on two parallel straight telescopic guide rails 205. The telescopic cylinder 209 below the fixed plate 206 simultaneously retracts and extends the left and right telescopic plates 207 and 208, completing the left and right box-supporting of the lower clamp. A vertical support cylinder 211 is installed on the lower fixture. The extended shaft end of the vertical support cylinder 211 is installed on the connecting piece 217 on the upper fixture, and the extension of the cylinder completes the vertical support function. Similarly, the upper fixture is provided with a fixed guide plate 212, and a first telescopic plate 213 and a second telescopic plate 214 on both sides, which are respectively installed on the linear guide rails 208 on both sides. At the same time, the first telescopic plate 213 and the second telescopic plate 214 are installed on the first cylinder 215 and the second cylinder 216. The left and right support of the upper fixture is completed by the simultaneous retraction and extension of the first cylinder 215 and the second cylinder 216. Here, the left and right support of the upper fixture and the left and right support of the lower fixture move simultaneously. After completion, the vertical support cylinder 211 extends to complete the vertical support function. This completes the box support function. The above is the single-station operation mode. The dual-station operation is carried out synchronously on the same principle.
