Referring to fig. 1 and fig. 2, an embodiment of the present invention provides a tobacco bale turning system, which is used for turning over a tobacco bale by 180 degrees in an unpacking process to remove an outer carton and an inner carton sleeved outside the tobacco bale and a paperboard padded between the tobacco bale and the inner carton by matching with a manipulator. The tobacco bale turning system comprises a support 1, a lifting assembly 2, a clamping assembly 3 and a turning assembly 4. The stand 1 is configured to provide support. The lifting assembly 2 comprises a first driving part 21, a first transmission mechanism 22 and a lifting part 23, wherein the lifting part 23 is in driving connection with the first driving part 21 through the first transmission mechanism 22 so as to lift under the driving of the first driving part 21. The clamping assembly 3 comprises a lifting part 23, a second driving part 31, a second transmission mechanism 32 and at least one pair of clamping discs 33; the lifting unit 23 is attached to the lifting unit 23 to be synchronously lifted and lowered with the lifting unit 23; the second driving portion 31 is mounted on the lifting portion 23, and the clamping plate 33 is in driving connection with the second driving portion 31 through the second transmission mechanism 32 so as to move linearly under the driving of the second driving portion 31, and further clamp and loosen the cigarette packet 60. The reversing assembly 4 comprises a third driving part 41 and a third transmission mechanism 42, wherein the third driving part 41 is arranged on the second driving part 31; the third driving portion 41 is also drivingly connected to the clamping disk 33 through a third transmission mechanism 42 to rotate the clamping disk 33.

In the tobacco production, the unpacking procedure is to take a cigarette packet 60 with a box from a formula library, and the cigarette packet 60 is sleeved with an inner box and an outer box. Each layer of boxes is open at one side. The outer carton can be removed directly from above the cigarette pack 60 and then the robot removes the cardboard lining between the outer carton and the cigarette pack 60. Then, the cigarette packet turning system provided by the embodiment of the invention turns the cigarette packet 60 with the inner box by 180 degrees, and then the mechanical arm takes down the inner box and the paperboard between the inner box and the cigarette packet 60 from the upper part.

The weight of naked tobacco bale is about 200KG, and is very heavy, and support 1 need not bear the weight of tobacco bale 60, still bear the weight of lifting unit 2, clamping component 3, upset subassembly 4. In some embodiments, therefore, the stent 1 adopts the following structure: the support 1 comprises a column 11 and a beam 12. The uprights 11 are arranged in pairs; the cross member 12 is mounted to a pair of uprights 111. Wherein the lifting assembly 2 is mounted to the top end of the upright 11 or to the cross beam 12. The lifting assembly 2 and the clamping assembly 3 are both located between a pair of uprights 11.

The entire holder 1 is substantially portal-shaped. Each upright post 11 and each cross beam 12 can be made of stainless steel. Of course, in order to make the structure of the bracket 1 more stable, the upright post 11 and the cross beam 12 may be formed by welding a plurality of thin rods, or by welding a plurality of plates.

The turning sequence of the cigarette packet 60 is as follows: tobacco bale 60 on shuttle 40 is gripped by gripping assembly 3, and tobacco bale 60 is then lifted a distance by lifting assembly 2 to leave shuttle 40. The lifting is to avoid that shuttle 40 obstructs the turning of cigarette packet 60 during the turning of cigarette packet 60. The packets 60 of cigarettes are then turned 180 ° using the turning assembly 4. Then, the cigarette packet 60 is linearly lowered to the shuttle car 40 by the lifting assembly 2. Finally, gripping assembly 3 releases packet 60 and shuttle 40 transfers packet 60 to the station determined by the next action. The respective implementation modes of the lifting assembly 2, the clamping assembly 3 and the overturning assembly 4 are described in sequence.

Referring to fig. 1, the lifting assembly 2 includes a first driving part 21, a first transmission mechanism 22, and a lifting part 23. The first drive unit 21 includes a speed reducer. In some embodiments, first transmission 22 includes a first bearing seat 221, a link 222, a first sprocket 223, a second sprocket 224, and a chain 225. The first bearing housings 221 are arranged in pairs and in one-to-one correspondence with the columns 11. The connecting rod 222 is rotatably mounted between the two first bearing seats 221. The link 222 is drivingly connected to the first driving unit 21. The first sprocket 223 is mounted to the link 222.

The lifting unit 23 is fixed to the chain 225 so as to be lifted and lowered as the chain 225 rotates.

The whole power transmission process is as follows: the first driving unit 21 employs a speed reducer, and the speed reducer drives the connecting rod 222 to rotate. The ascending and descending unit 23 ascends and descends by the normal rotation and reverse rotation of the first driving unit 21. A first sprocket 223 is fixedly mounted on the link 222, and the first sprocket 223 rotates along with the rotation of the link 222. The first sprocket 223 is drivingly connected to the second sprocket 224 by a chain 225. The second sprocket 224 is rotatably mounted to the upright 11 via a second bearing housing 226. During the rotation of the first sprocket 223, the chain 225 engaged with the first sprocket 223 is driven to rotate between the first sprocket 223 and the second sprocket 224. In the process of the rotation of the chain 225, the lifting unit 23 fixed to the chain 225 is linearly lifted up and down along with the rotation of the chain 225. The lifting part 23 is, for example, a frame structure, and serves as a bearing base for the clamping assembly 3.

Both ends of the lifting part 23 are fixedly connected with one chain 225 respectively. According to the technical scheme, the two chains 225 are driven to synchronously rotate through the first driving part 21, so that the lifting part 23 is stably lifted.

The linear lifting of the lifting unit 23 is within a certain range, and the upper limit position is a position where the cigarette packet 60 can be normally turned over without being interfered by other components (such as the shuttle car 40). The lower limit position is such that cigarette packet 60 is placed on the carrying surface of shuttle 40. Referring to fig. 1 and 2, therefore, in some embodiments, the lifting assembly 2 further includes a lift stop mechanism 24, and the lift stop mechanism 24 is mounted adjacent to the first drive portion 21 to stop the first drive portion 21 after the clamping disk 33 reaches the extreme lift position.
