DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model.

It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0024] See also Figure 1-5A strip box conveying device according to an embodiment of the utility model comprises a first ejecting member 2, a second ejecting member 4, a lifting member 3, and a conveying member 1 for conveying a strip box 5 from a first station to a pushing end. The first ejecting member 2 is arranged at a first side of the pushing end of the conveying member 1, and is used to push the strip box 5 located at the pushing end from the conveying member 1 to the lifting member 3. The lifting member 3 is arranged at a second side of the pushing end of the conveying member 1, and is used to drive the strip box 5 to move to a first height matching the second ejecting member 4. The second ejecting member 4 is used to push the strip box 5 on the lifting member 3 to a second station.

[0025] Here, the conveying member 1 conveys the strip box 5 along its axis, wherein the first station is arranged at one end of the conveying member 1 and the pushing end is arranged at the other end of the conveying member 1. After the strip box 5 is conveyed to the pushing end, the lifting member 3 moves to a position where the top end matches the top end of the conveying member 1, and the first pushing member 2 pushes the first side of the strip box 5, thereby pushing the strip box 5 out of the conveying member 1, and the lifting member 3 receives the strip box 5, and then the lifting member 3 drives the strip box 5 to move to a first height matching the second pushing member 4, and the lifting member 3 stops moving, and the second pushing member 4 pushes the strip box 5 to the second station, thereby avoiding the strip box 5 from falling directly from the conveying member 1 to the first height and causing the tobacco rods in the strip box 5 to be vibrated, and the lifting member 3 effectively delays the descending speed of the strip box 5, avoids the vibration and noise caused by the free fall of the strip box 5 group in the box library, prevents the surface of the strip box 5 from being damaged, and ensures the stacking order of the strip boxes 5 and the stability of the appearance of the strip boxes 5 themselves.

[0026] The conveying member 1 may include a belt 11 for conveying the strip box 5, a first power structure for driving the belt 11, and two first stop plates 12 respectively arranged on both sides of the belt 11. The two first stop plates 12 are used to stop the two sides of the strip box 5 when the strip box 5 is conveyed from the first workstation to the pushing end.

[0027] Specifically, the belt 11 is arranged horizontally, and the first power structure may include an active roller, a driven roller, and a first motor for driving the active roller. The two ends of the belt 11 are respectively sleeved with the active roller and the driven roller. The first stop plate 12 may abut against the side of the belt 11, and the first stop plate 12 is perpendicular to the axis of the belt 11. One first stop plate 12 is arranged on the first side of the belt 11, and the other first stop plate 12 is arranged on the second side of the belt 11. The two first stop plates 12 are arranged symmetrically, one end of the belt 11 is arranged at the first station, and the other end is arranged at the pushing end. The first stop plate 12 extends from the first station to the first stop position adjacent to the pushing end, so that the first stop plate 12 cannot stop the strip box 5 of the belt 11 at the pushing end, which facilitates the second ejection member 4 to push the strip box 5 onto the supporting member 3.

[0028] The conveying member 1 may further include a second stop plate 13 disposed on a third side of the pushing end of the conveying member 1 for stopping the strip box 5 located at the pushing end.

[0029] Specifically, the second stopper plate 13 can prevent the strip box 5 from sliding out of one end of the belt 11, and limit the strip box 5 when the strip box 5 moves along the extension direction of the belt 11, so as to prevent the strip box 5 from sliding out of the belt 11 under the action of its inertia when the belt 11 transports the strip box 5 to the pushing end. The axis of the second stopper plate 13 is perpendicular to the axis of the belt 11.

[0030] The first pushing member 2 may include a first pushing plate 21 and a first electric cylinder 22 connected to the first pushing plate 21; the first electric cylinder 22 is used to push the first pushing plate 21 to move from a first initial position to above the belt 11, so that the first pushing plate 21 pushes the strip box 5 located at the pushing end of the belt 11 to the supporting member 3; the first electric cylinder 22 is used to drive the first pushing plate 21 to move to the first initial position when the first pushing plate 21 moves a first preset distance in a direction close to the supporting member 3.

[0031] Specifically, the axis of the first push plate 21 is perpendicular to the axis of the belt 11. The first electric cylinder 22 drives the first push plate 21 to move linearly, and the movement direction of the first push plate 21 is perpendicular to the axis of the belt 11. The first initial position is the position of the first push plate 21 when the first electric cylinder 22 is not extended. When the first electric cylinder 22 is extended, the first push plate 21 is driven to move. When the first electric cylinder 22 drives the first push plate 21 to move toward the direction of the supporting member 3 by the first preset distance, the first push plate 21 pushes the box 5 on the belt 11 to the supporting member 3.

[0032] The lifting member 3 may include a support plate 31 and a lifting structure 32 connected to the bottom end of the support plate 31, wherein the support plate 31 is parallel to the belt 11; the lifting structure 32 is used to push the support plate 31 to move upward to a second height flush with the portion of the belt 11 located at the pushing end, so that the support plate 31 receives the strip box 5 pushed out from the belt 11; the lifting structure 32 is used to drive the support plate 31 to move downward to a first height matching the second pushing member 4.

[0033] Specifically, the lifting structure 32 is a third electric cylinder used to drive the support plate 31 to move linearly, and the top of the third electric cylinder is connected to the top of the support plate 31. The support plate 31 can be a U-shaped support plate 31, and the top ends of the U-shaped support plate 31 are respectively abutted against the bottom end of the strip box 5. The axis of the support plate 31 is perpendicular to the axis of the belt 11, and the lifting structure 32 drives the support plate 31 to move up and down linearly, and the movement direction of the support plate 31 is perpendicular to the axis of the belt 11. The lifting structure 32 pushes the support plate 31 to move to the second height, and the top of the support plate 31 is kept flush with the part of the belt 11 at the pushing end, which facilitates the strip box 5 to move from the belt 11 to the support plate 31.

[0034] The second ejection member 4 may include a second push plate 41 and a second electric cylinder 42 connected to the second push plate 41; the second electric cylinder 42 is used to push the second push plate 41 from the second initial position to above the support plate 31 when the support plate 31 moves to the first height, so that the second push plate 41 pushes the box 5 located on the support plate 31 to the second workstation; the second electric cylinder 42 is used to drive the second push plate 41 to move to the second initial position when the second push plate 41 moves a second preset distance in the direction close to the second workstation.

[0035] Specifically, the axis of the second push plate 41 is parallel to the axis of the belt 11, and the second electric cylinder 42 drives the second push plate 41 to move linearly, and the movement direction of the second push plate 41 is parallel to the axis of the belt 11. The second initial position is the position of the second push plate 41 when the second electric cylinder 42 is not extended. When the second electric cylinder 42 is extended, it drives the second push plate 41 to move. The second electric cylinder 42 drives the second push plate 41 to move a second preset distance toward the second station, and at this time, the second push plate 41 pushes the box 5 on the support plate 31 to the second station.

[0036] The lifting member 3 may also include two third stop plates 33 for limiting the two sides of the strip box 5 when the strip box 5 is pushed out from the belt 11 onto the support plate 31. The two third stop plates 33 are arranged in parallel. One third stop plate 33 arranged close to the second ejecting member 4 is penetrated by a first push through hole 331 for the second push plate 41 to pass through, and the other third stop plate 33 arranged away from the second ejecting member 4 is penetrated by a second push through hole 332 for the strip box 5 to pass through.

[0037] Specifically, the third stopper plate 33 is vertically arranged, and the axis of the third stopper plate 33 is perpendicular to the axis of the belt 11. The two third stopper plates 33 can not only limit the up and down movement of the support plate 31, but also limit the strip box 5 when the support plate 31 drives the strip box 5 to descend, so as to prevent the strip box 5 from sliding out of the two sides of the support plate 31. The two third stopper plates 33 are respectively arranged on the two sides of the support plate 31, one is arranged close to the second ejector 4, and the other is arranged close to the second station.

[0038] The lifting member 3 may further include a fourth stop plate 34 for stopping an end of the strip box 5 away from the first push plate 21 when the strip box 5 is pushed out from the belt 11 onto the support plate 31 .

[0039] Specifically, the fourth stop plate 34 and the two third stop plates 33 are perpendicular to the support plate 31, and the two ends of the fourth stop plate 34 are detachably connected to the two third stop plates 33. When the first push plate 21 pushes the strip box 5 from the belt 11 to the support plate 31, the force of the first push plate 21 is too large, which will cause the strip box 5 to slide off the end of the support plate 31 away from the first push plate 21. At this time, the fourth stop plate 34 stops the strip box 5 to ensure that the strip box 5 is stably placed on the support plate 31.

[0040] A first elastic shock-absorbing layer may be provided on a side of the second stop plate 13 close to the belt 11 .

[0041] Specifically, the first elastic shock-absorbing layer can provide shock absorption to the barrel 5 , decelerate the barrel 5 , and prevent the barrel 5 from being damaged when the barrel 5 collides with the second stop plate 13 .

[0042] A second elastic shock-absorbing layer may be provided on a side surface of the fourth stop plate 34 close to the supporting plate 31 .

[0043] Specifically, the second elastic shock-absorbing layer can provide shock absorption to the barrel 5 , decelerate the barrel 5 , and prevent the barrel 5 from being damaged when the barrel 5 collides with the fourth stop plate 34 .

[0044] Specifically, a control member may be further included, and the control member may control the conveying member 1 , the first pushing member 2 , the lifting member 3 , and the second pushing member 4 . A first pressure sensor is provided on a side of the second stop plate 13 close to the belt 11. When the strip box 5 abuts against the second stop plate 13, the first pressure sensor detects a first pressure value, and the control component controls the lifting structure 32 so that the lifting structure 32 drives the support plate 31 to rise. After a period of time, the support plate 31 rises to a second height flush with the belt 11. At this time, the control component can control the first electric cylinder 22, and the first electric cylinder 22 drives the first push plate 21, so that the first push plate 21 pushes the strip box 5 from the belt 11 to the support plate 31. A second pressure sensor is provided on the top surface of the support plate 31. When the strip box 5 moves onto the support plate 31, the second pressure sensor detects a second pressure value, and the control component controls the lifting structure 32 so that the lifting structure 32 drives the support plate 31 down to the first height. Finally, the control component controls the second electric cylinder 42, and the second electric cylinder 42 drives the second push plate 41, so that the second push plate 41 pushes the strip box 5 from the support plate 31 to the second workstation.

[0045] Specifically, the strip box 5 is a hard strip box 5, and the YB95 hard strip packaging machine is a type of cigarette packaging machine, which has strong adaptability and is widely used in packaging strip boxes 5 of cigarettes of various specifications. The first electric cylinder 22, the second electric cylinder 42, and the third electric cylinder all include servo motors.

This purpose can be achieved by using the first electric cylinder 22 and the second electric cylinder 42 with controllable speed, the lifting structure 32 to combine the support plate 31, and the support plate 31 contacts the bottom surface of the strip box 5. Through program control of the first electric cylinder 22, the second electric cylinder 42, and the lifting structure 32, a plurality of strip boxes 5 are arranged up and down to form a strip box 5 group, the first push plate 21 pushes a strip box 5 group onto the support plate 31, the second electric cylinder 42 controls the second push plate 41 to push out the strip box 5 located at the bottom of the strip box 5 group, and before the second push plate 41 retreats, the second push plate 41 supports the other strip boxes 5 in the strip box 5 group, and the lifting structure 32 pushes the support plate 31 to continue to move upward, so that the top end of the support plate 31 can contact and support the strip box 5 at the bottom of the strip box 5 group, and the second push plate 41 retreats. At this time, the strip box 5 group is supported by the support plate 31, and the lifting structure 32 controls the support plate 31 to move downward, slowly descends the support plate 31, so that the strip box 5 group descends, and the strip box 5 group descends to a first height matching the second push plate 41, and the second push plate 41 can push out the strip box 5 at the bottom of the strip box 5 group again.
