Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco equipment, in particular to a cigarette box clamping detection device for a box stripping machine and the box stripping machine. Background Art
[0002] In the process of tobacco silk production, the production of tobacco sheets generally requires the unpacking of cigarette boxes. Among them, the unpacking of cigarette boxes is the main process of unpacking cigarette boxes, which is to separate the cigarette boxes set on the outside of the carton from the carton, which is generally achieved by a box stripper. When unpacking the cigarette box, the cigarette box is placed between the left and right arms of the box stripper. The box stripper contracts the left and right arms to clamp the cigarette box, and then runs upward to separate the cigarette box from the carton to achieve the box stripping effect. Because the distance between the two arms of the box stripper is constant when it is in a clamping state, that is, no matter how the size of the cigarette box changes, the distance between the left and right arms of the box stripper is constant, so the requirements for the size of the cigarette box when stripping are relatively strict. When the size of the incoming cigarette box is too large, the two arms of the box stripper clamp the cigarette box too tightly, and the box stripper will move upward with some cigarette sheets, causing the cigarette box to be stratified after being removed from the box, affecting the processing of subsequent steps; when the size of the incoming cigarette box is too small, the two arms of the box stripper clamp the cigarette box too loosely, and the two arms and the cigarette box slip when the box stripper moves upward, which will also affect the box stripping effect. Utility Model Content
[0003] The purpose of the utility model is to solve the problem that when the sizes of incoming cigarette boxes are not uniform, the box stripper often clamps the cigarette boxes too tightly or too loosely.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0025] like Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 The schematic diagrams of the structure of the cigarette box clamping detection device provided by an embodiment of the utility model when the cigarette box is not clamped and when the cigarette box is clamped are shown respectively. The box unloader comprises a left clamping arm 1 and a right clamping arm 2, and the left clamping arm 1 and the right clamping arm 2 can move towards each other to clamp the cigarette box 3 located therebetween. In this embodiment, the cigarette box clamping detection device comprises:
[0026] An elastic member, which is arranged on the inner side of the left clamp arm 1 and / or the right clamp arm 2 and is used to contact the side wall of the cigarette box 3;
[0027] A detection member 5, which is disposed on the left clamp arm 1 and / or the right clamp arm 2, with a detection end of the detection member 5 facing the elastic member, and is used to detect deformation of the elastic member;
[0028] A control unit is electrically connected to the detection component 5 to receive a detection signal from the detection component 5 .
[0029] This technical solution is adopted, by arranging an elastic member on the left clamp arm 1, or the right clamp arm 2, or the left clamp arm 1 and the right clamp arm 2, and arranging a detection member 5 at a position corresponding to the elastic member, so as to detect the deformation of the elastic member in the process of clamping the cigarette box 3, and then judge the clamping state of the cigarette box 3 by the deformation. Specifically, when the left clamp arm 1 and the right clamp arm 2 move toward each other and the elastic member contacts the side wall of the cigarette box 3, the elastic member is squeezed by the cigarette box 3 to produce deformation. When the deformation of the elastic member reaches a certain degree, the detection member 5 will send a detection signal to the control unit, and the control unit will control the left clamp arm 1 and the right clamp arm 2 to stop moving after receiving the detection signal. At this time, the clamping force applied by the left clamp arm 1 and the right clamp arm 2 to the cigarette box 3 is just right, that is, the cigarette box 3 can be clamped to perform the box removal operation, and the cigarette box 3 will not be damaged due to excessive clamping force. Therefore, the cigarette box clamping detection device provided by the utility model can control the clamping distance between the left clamping arm 1 and the right clamping arm 2 according to the size of the cigarette box, and perform the box removal operation while ensuring that the cigarette box is clamped and not damaged, thereby improving the box removal effect.
[0030] Specifically, the elastic member can be arranged on one of the left clamp arm 1 and the right clamp arm 2, or one elastic member can be arranged on each of the left clamp arm 1 and the right clamp arm 2, and can be arranged specifically according to actual needs. Correspondingly, the detection member 5 and the elastic member to be detected are arranged on the same clamp arm to detect the deformation of the elastic member. That is, when the elastic member is arranged on one of the left clamp arm 1 and the right clamp arm 2, the detection member 5 is arranged on the clamp arm corresponding to the elastic member. In this case, the control unit controls the left and right clamp arms to stop moving after receiving the detection signal of the detection member 5. When the elastic member is arranged on both the left clamp arm 1 and the right clamp arm 2, the detection member 5 is correspondingly arranged on the two clamp arms. In this case, the control unit controls the left and right clamp arms to stop moving after receiving the detection signal of the detection member 5 on the two clamp arms.
[0031] Furthermore, if Figure 1 As shown, in this embodiment, the elastic member is a spring sheet 4, which is arranged in an arc shape with the middle protruding toward the cigarette box 3, and the two ends of the spring sheet 4 are connected to the inner side of the left clamp arm 1 or the right clamp arm 2.
[0032] Specifically, the spring piece 4 is arranged on the inner side of the left clamp arm 1 or the right clamp arm 2, the middle part of which protrudes toward the direction of the cigarette box 3, and the two ends are fixed to the inner wall of the clamp arm by screws. The detection member 5 is arranged in the arm of the left clamp arm 1 or the right clamp arm 2, and the detection end of the detection member 5 is aligned with the middle part of the spring piece 4. After the spring piece 4 is squeezed by the cigarette box 3 and deformed to a certain extent, the detection member 5 detects the deformation and sends a detection signal to the control unit.
[0033] Optionally, the spring 4 is a metal spring to have better elasticity.
[0034] Optionally, the distance that the spring piece 4 protrudes from the surface of the corresponding left clamp arm 1 or right clamp arm 2 is 1-2 mm. With this technical solution, elastic deformation can be achieved and the shape can be restored after the box-unloading operation, so as to facilitate use in the next box-unloading operation.
[0035] Optionally, the detection component 5 is a proximity switch or a micro switch.
[0036] With this technical solution, after the spring sheet 4 is squeezed and deformed to a certain extent by the cigarette box 3, the detection member 5 detects the deformation of the spring sheet 4 and sends a detection signal to the control unit. In this embodiment, the deformation of the spring sheet 4 indirectly reflects the clamping force on the cigarette box 3. Regardless of the size of the cigarette box 3, the detection distance of the detection member 5 is constant, and the deformation caused by squeezing the spring sheet 4 is constant, that is, the clamping force is constant. By adjusting the distance between the detection end of the detection member 5 and the middle of the spring sheet 4, the size of the clamping force can be adjusted, thereby effectively ensuring the box removal effect.
[0037] It is worth noting that when the detection component 5 is a micro switch, the micro switch and the spring 4 can be an integral micro switch, or a separate micro switch and spring 4 can be used, and the utility model does not limit this.
[0038] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, an elastic component and a detection component 5 are respectively provided on the left clamp arm 1 and the right clamp arm 2, and the two elastic components are arranged opposite to each other. By adopting this technical solution, the reliability of detection can be ensured.
[0039] Furthermore, it also includes an alarm mechanism, which is electrically connected to the control unit and is used to sound an alarm when the control unit does not receive the detection signal within a preset time. Optionally, the alarm mechanism includes an audible and visual alarm.
[0040] With this technical solution, when there is no cigarette box 3 under the box stripper, in order to avoid collision between the left and right clamp arms or failure of the detection member 5, if the control unit does not receive the detection signal within a preset time, the control unit sends an alarm signal to the alarm mechanism, and the alarm mechanism sends an alarm after receiving the alarm signal. That is to say, when the control unit does not receive the detection signal within a preset time, the sound and light alarm is sent through the sound and light alarm to remind the operator that there is no cigarette box 3 under the box stripper or the equipment is faulty, so as to deal with it in time.
[0041] According to the cigarette box clamping detection device provided by the utility model, the spring piece 4 and the detection member 5 are arranged on the left clamp arm 1 and / or the right clamp arm 2 of the box stripping machine. When the left and right clamp arms gradually shrink, the spring piece 4 is squeezed by the cigarette box 3 and deforms. As the left and right clamp arms continue to shrink, the deformation of the spring piece 4 gradually increases. When the deformation of the spring piece 4 reaches a certain degree and the detection member 5 detects the spring piece 4, the detection member 5 sends a detection signal to the control unit. After receiving the detection signal, the control unit controls the left and right clamp arms to stop moving. At this time, the clamping force applied by the left clamp arm 1 and the right clamp arm 2 to the cigarette box 3 is just right, that is, the cigarette box 3 can be clamped to perform the box stripping operation, and the cigarette box 3 will not be damaged due to excessive clamping force.
[0042] The cigarette box clamping detection device provided by the utility model can control the clamping distance between the left clamping arm and the right clamping arm according to the size of the cigarette box, and perform the box removal operation while ensuring that the cigarette box is clamped and not damaged, thereby improving the box removal effect.
[0043] The embodiment of the utility model further provides a box stripping machine, comprising a left clamping arm 1, a right clamping arm 2 and the above-mentioned cigarette box clamping detection device arranged on the left clamping arm 1 and / or the right clamping arm 2.
[0044] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
