Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, in particular to an adjusting jig for an expansion device. Background Art

[0002] The YP18D case packer is an optomechanical and electrical integrated device for cigarette packaging, automating the entire process from collecting and stacking cartons to packing and sealing them. It improves packaging efficiency by enabling automated operations to accurately and quickly place items into cases according to the desired arrangement and quantity.

[0003] The YP18D cartoner's opening expansion device is designed to facilitate product entry into the packaging box. It expands the box's opening, allowing cigarette cartons to be loaded accurately and efficiently, minimizing collisions and jams between cigarette cartons and the box's edges.

[0004] The expansion device includes two lower corner panels spaced apart along a first direction, two upper corner panels spaced apart along the first direction, and a drive assembly. The two upper corner panels are located above the two lower corner panels along a second direction, and the two upper corner panels and the two lower corner panels enclose a rectangular guide channel. One end of the two lower corner panels and one end of the two upper corner panels are simultaneously inserted into the opening of the box. The two lower corner panels are located at the two lower corners of the box, and the two upper corner panels are located at the two upper corners of the box. The drive assembly drives the two upper corner panels and the two lower corner panels to expand the opening of the box, so that the stack of cigarettes can enter the box through the guide channel. During this process, the drive assembly can adjust the relative positions of the two lower corner panels and the two upper corner panels and the deflection angle relative to the axis of the guide channel, so that the expansion device can adapt to different models of boxes. When the drive assembly synchronously drives the two lower corner panels and the two upper corner panels, it is necessary to ensure that the deflection angles of the upper and lower corner panels relative to the axis of the guide channel are consistent.

[0005] After the drive assembly is repaired or has been in operation for a long time, the connection positions of the drive assembly with the upper and lower corner plates may change, resulting in inconsistent deflection angles of the upper and lower corner plates relative to the axis of the guide channel. This can cause the cigarette box to get stuck or even wrinkle when the cigarette stack enters the box. To this end, the staff needs to adjust the connection position relationship between the drive assembly and the upper and lower corner plates, respectively, so that the deflection angles of the upper and lower corner plates relative to the axis of the guide channel are consistent.

[0006] When adjusting the connection between the drive assembly and the upper or lower corner plate, the operator manually adjusts the deflection angle of each upper or lower corner plate to 0° and the deflection angle of each lower corner plate to 0° to ensure that the deflection angle of each upper or lower corner plate relative to the axis of the guide channel is consistent. The operator then secures the connection between the drive assembly and the upper or lower corner plate. However, during this process, the operator's hand shaking makes it difficult to maintain the deflection angle of the upper or lower corner plate to the axis of the guide channel at 0°, resulting in poor maintenance results.

[0007] Therefore, there is an urgent need for an expansion device adjustment jig to solve the above problems. Summary of the Invention

[0043] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0044] like Figure 1As shown, the expansion device 100 includes two lower corner panels 101 spaced apart along a first direction X, two upper corner panels 102 spaced apart along the first direction X, and a drive assembly 104. The two upper corner panels 102 are positioned above the two lower corner panels 101 along a second direction Y. The two upper corner panels 102 and the two lower corner panels 101 form a rectangular guide channel 103. One end of the two lower corner panels 101 and one end of the two upper corner panels 102 are simultaneously inserted into the opening of the box. The two lower corner panels 101 are located at the two lower corners of the box, and the two upper corner panels 102 are located at the two upper corners of the box. The drive assembly 104 drives the two upper corner panels 102 and the two lower corner panels 101 to expand the box opening, allowing the cigarette stack to enter the box through the guide channel 103. During this process, the drive assembly 104 can adjust the relative positions of the two lower corner panels 101 and the two upper corner panels 102, as well as their deflection angles relative to the axis of the guide channel 103, so that the expansion device 100 can adapt to different box models. When the drive assembly 104 synchronously drives the two lower corner panels 101 and the two upper corner panels 102, it is necessary to ensure that the deflection angles of the upper corner panels 102 and the lower corner panels 101 relative to the axis of the guide channel 103 are consistent.

[0045] After the drive assembly 104 is repaired or has been in operation for a long time, the connection positions of the drive assembly 104 with the upper corner plate 102 and the lower corner plate 101 may change, resulting in inconsistent deflection angles of the upper corner plate 102 and the lower corner plate 101 relative to the axis of the guide channel 103. This can cause the cigarette box to get stuck or even wrinkle when the cigarette stack enters the box. To this end, the staff needs to adjust the connection position relationship between the drive assembly 104 and the upper corner plate 102, as well as the connection position relationship between the drive assembly 104 and the lower corner plate 101, so that the deflection angles of the upper corner plate 102 and the lower corner plate 101 relative to the axis of the guide channel 103 are consistent.

[0046] Specifically, the drive assembly 104 includes two upper adjustment plates 1041, each corresponding to the two upper angled plates 102. Upper waist-shaped holes 1042 are provided on each upper adjustment plate 1041. Locking bolts pass through these holes and are screwed into the corresponding upper angled plates 102. Adjusting the position of the locking bolts within these holes allows the deflection angle between the upper angled plates 102 and the axis of the guide channel 103 to be adjusted. The drive assembly 104 also includes two lower adjustment plates, each corresponding to the two lower angled plates 101. Lower waist-shaped holes are provided on each lower adjustment plate. Locking bolts pass through these holes and are screwed into the corresponding lower angled plates 101. Adjusting the position of the locking bolts within these holes allows the deflection angle between the lower angled plates 101 and the axis of the guide channel 103 to be adjusted. After maintenance or after prolonged operation of the drive assembly 104, the position of the locking bolts within the upper or lower waist-shaped holes 1042 may need to be adjusted. The specific structure of the driving component 104 is prior art and will not be described in detail here.

[0047] When adjusting the connection between the drive assembly 104 and the upper or lower corner plate 102, 101, the operator manually adjusts the deflection angle between each upper corner plate 102 and the axis of the guide channel 103 to 0°, and the deflection angle between each lower corner plate 101 and the axis of the guide channel 103 to 0°, to ensure that the deflection angles of each upper or lower corner plate 102 and 101 are consistent with each other. The operator then secures the connection between the drive assembly 104 and the upper or lower corner plate 102, and vice versa. However, due to the operator's hand shaking, it is difficult to maintain the deflection angle between the upper or lower corner plate 102 and the axis of the guide channel 103 at 0°, resulting in poor maintenance results.

[0048] To solve the above problems, Figures 2 to 4As shown, this embodiment provides a flaring device adjustment fixture for being arranged in a guide channel 103 of the flaring device 100. The flaring device 100 includes two lower corner plates 101 and two upper corner plates 102. The two lower corner plates 101 and the two upper corner plates 102 are all L-shaped and surround the guide channel 103. The flaring device adjustment fixture includes a first adjustment component and a second adjustment component. The first adjustment component includes a first telescoping device 11 and two lower rectangular blocks 12. The two lower rectangular blocks 12 are respectively fixed at both ends of the first telescoping device 11 along the first direction X. The first telescoping device 11 can be telescoping along the first direction X. The two lower rectangular blocks 12 are one-to-one with the two lower corner plates 101. The two adjacent side surfaces of the lower rectangular block 12 are used to fit with the two side surfaces of the corresponding lower corner plate 101; the second adjustment component includes two second telescoping devices 21 and two upper rectangular blocks 22. The two lower rectangular blocks 12, the two second telescoping devices 21 and the two upper rectangular blocks 22 correspond one to one. The upper rectangular blocks 22 and the lower rectangular blocks 12 are arranged on both sides of the second telescoping device 21 along the second direction Y. The second telescoping device 21 can be telescoped along the second direction Y. The two upper rectangular blocks 22 correspond one to one with the two upper corner plates 102. The two adjacent side surfaces of the upper rectangular block 22 are used to fit with the two side surfaces of the corresponding upper corner plate 102; the first direction X and the second direction Y are perpendicular.

[0049] It is known that the deflection angle between the two lower corner plates 101 and the axis of the guide channel 103 is 0°, and when the deflection angle between the two upper corner plates 102 and the axis of the guide channel 103 is 0°, the length of the guide channel 103 along the first direction X is a, and the length along the second direction Y is b. At this time, the expansion device adjustment fixture is set in the guide channel 103, and by adjusting the length of the first telescopic member, the distance between the two surfaces of the two lower rectangular blocks 12 that are away from each other along the first direction X is equal to a. The two second telescopic members are adjusted to make the distance between the two surfaces of the lower rectangular block 12 and the corresponding upper rectangular block 22 that are away from each other along the second direction Y equal to b. The staff manually fits the two side surfaces of the lower corner plate 101 with the two side surfaces of the corresponding lower rectangular block 12 to achieve a deflection angle of 0° between the lower corner plate 101 and the axis of the guide channel 103. At this time, the staff can fix the connection position relationship between the lower corner plate 101 and the drive component 104 of the expansion device 100; the staff manually fits the two side surfaces of the upper corner plate 102 with the two side surfaces of the corresponding upper rectangular block 22 to achieve a deflection angle of 0° between the upper corner plate 102 and the axis of the guide channel 103. At this time, the staff can fix the connection position relationship between the upper corner plate and the drive component 104 of the expansion device 100. Through the above operations, the staff fits the upper corner plate 102 on the corresponding upper rectangular block 22, and fits the lower corner plate 101 on the corresponding lower rectangular block 12 to avoid shaking of the upper corner plate 102 and the lower corner plate 101. The staff can then accurately adjust the connection position relationship between the drive component 104 and the upper corner plate 102, as well as the connection position relationship between the drive component 104 and the lower corner plate 101, thereby improving the maintenance effect.

[0050] Optionally, the first adjustment component also includes two first lasers 13, which are arranged one-to-one on the two lower rectangular blocks 12, and the two surfaces of the lower rectangular block 12 and the corresponding lower corner plate 101 are attached as the lower reference surfaces 121. The first laser 13 emits two light beams along the third direction Z, and the two light beams emitted by the first laser 13 are respectively flush with the two lower reference surfaces 121 of the corresponding lower rectangular block 12; the second adjustment component also includes two second lasers 23, which are arranged one-to-one on the two upper rectangular blocks 22, and the two surfaces of the upper rectangular block 22 and the corresponding upper corner plate 102 are attached as the upper reference surfaces 221. The second laser 23 emits two light beams along the third direction Z, and the two light beams emitted by the second laser 23 are respectively flush with the two upper reference surfaces 221 of the corresponding upper rectangular block 22; the third direction Z is perpendicular to the first direction X and the second direction Y, respectively. In this embodiment, the lower corner plate 101 includes a first plate and a second plate arranged at a 90-degree angle. The two adjacent lower reference surfaces 121 of the lower rectangular block 12 abut against the first plate and the second plate, respectively. At this point, the first laser 13 emits two laser beams, each flush with the two lower reference surfaces 121 of the lower rectangular block 12. If the first plate and the second plate are respectively aligned with the two lower reference surfaces 121, the two laser beams can be emitted from the guide channel 103, and the two laser beams are aligned with the first plate and the second plate, respectively. If the first plate does not align with the corresponding lower reference surface 121, the corresponding laser beam will not be fully emitted from the guide channel 103 or will be spaced apart from the corresponding first plate. If the second plate does not align with the corresponding lower reference surface 121, the corresponding laser beam will not be fully emitted from the guide channel 103 or will be spaced apart from the corresponding second plate. The method for determining whether the upper corner plate 102 is completely in contact with the two upper reference surfaces 221 of the upper rectangular block 22 by the second laser 23 is the same as the method for determining whether the lower corner plate 101 is completely in contact with the two lower reference surfaces 121 of the lower rectangular block 12 by the first laser 13, and will not be repeated here.

[0051] Optionally, the first laser 13 includes two laser heads, each of which sets two laser beams along the third direction Z. The second laser 23 includes two laser heads, each of which sets two laser beams along the third direction Z.

[0052] Optionally, the expansion device adjustment jig further includes a projection plate 3, which is disposed on one side of the expansion device 100 along the third direction Z. The projection plate 3 abuts the upper corner plate 102 and the lower corner plate 101. The projection plate 3 is opposite to the laser exit hole of the first laser 13, and the projection plate 3 is opposite to the laser exit hole of the second laser 23. In this embodiment, when the first plate and the second plate of the lower corner plate 101 are respectively attached to the two lower reference surfaces 121 of the corresponding lower rectangular block 12, the two laser beams emitted by the first laser 13 can form two complete light spots on the projection plate 3. When the first plate and the second plate of the lower corner plate 101 are respectively at an angle to the two lower reference surfaces 121 of the corresponding lower rectangular block 12, the two laser beams emitted by the first laser 13 have no light spots on the projection plate 3, or have partial light spots, or the light spots are spaced apart from the corresponding first plate or second plate. By observing the presence of a light spot on the projection plate 3, the size of the light spot, and the relative position of the light spot with the corresponding first plate or second plate, it is possible to more clearly and intuitively determine whether the lower corner plate 101 is completely attached to the two lower reference surfaces 121 of the lower rectangular block 12. Specifically, when the lower corner plate 101 deflects toward the axis of the guide channel 103, the lower corner plate 101 blocks the laser beam, resulting in no light spot being formed on the projection plate 3, or an incomplete light spot. When the lower corner plate 101 deflects toward the axis away from the guide channel 103, the lower corner plate 101 moves away from the laser beam, resulting in the light spot on the projection plate 3 being spaced apart from the lower corner plate 101.

[0053] Similarly, by observing whether the two laser beams emitted by the second laser 23 form a light spot on the projection plate 3, the size of the light spot, and the relative position of the light spot and the corresponding upper corner plate 102, it is possible to more clearly and intuitively determine whether the upper corner plate 102 is completely attached to the two upper reference surfaces 221 of the upper rectangular block 22.

[0054] Optionally, the first telescopic member 11 includes a first telescopic rod 111, a first telescopic sleeve 112, and a first stopper 113. The first telescopic sleeve 112 is provided with a first sliding hole. The first telescopic rod 111 is inserted into the first sliding hole and slides with the first telescopic sleeve 112. The first telescopic rod 111 and the first telescopic sleeve 112 are respectively fixed to the two lower rectangular blocks 12. The first stopper 113 allows the first telescopic rod 111 and the first telescopic sleeve 112 to have two relative fixed and relative sliding states. In this embodiment, the first telescopic rod 111 slides within the first sliding hole, thereby adjusting the spacing between the two lower rectangular blocks 12. When the spacing between the two lower rectangular blocks 12 is adjusted, the first stopper 113 fixes the relative position of the first telescopic rod 111 and the first telescopic sleeve 112, thereby fixing the relative position of the two lower rectangular blocks 12 and the spacing between the two upper rectangular blocks 22 along the first direction X.

[0055] like Figure 3As shown, optionally, the first limiting member 113 includes a first locking pin 115, a first limiting screw sleeve a116 and a first limiting screw sleeve b117, and the peripheral wall of the first telescopic sleeve 112 is provided with a first waist-shaped sliding hole 114 along the first direction X, and the first waist-shaped sliding hole 114 is connected to the first sliding hole, and the first locking pin 115 is passed through the first waist-shaped sliding hole 114 and is fixedly connected to the first telescopic rod 111, and the outer peripheral wall of the first telescopic sleeve 112 is provided with an external thread, and the first limiting screw sleeve a116 and the first limiting screw sleeve b117 are respectively sleeved on the first telescopic sleeve 112 and respectively screwed to the first telescopic sleeve 112, and the first limiting screw sleeve a116 and the first limiting screw sleeve b117 are located on both sides of the first locking pin 115 along the first direction X. In this embodiment, the first telescopic rod 111 slides in the first sliding hole, and then the first telescopic rod 111 drives the first locking pin 115 to slide in the first waist-shaped sliding hole 114. When the relative position of the first telescopic rod 111 and the first telescopic sleeve 112 is determined, the first limiting screw sleeve a116 and the first limiting screw sleeve b117 are screwed so that the first limiting screw sleeve a116 and the first limiting screw sleeve b117 clamp the first locking pin 115 along the first direction X, thereby limiting the position of the first locking pin 115 in the first waist-shaped sliding hole 114, so that the relative position of the first telescopic rod 111 and the first telescopic sleeve 112 is fixed.

[0056] like Figure 2 As shown, in other embodiments, the first limiting member 113 includes a fixing bolt, which penetrates into the first waist-shaped sliding hole 114 and is screwed to the first telescopic rod 111. When the relative position of the first telescopic rod 111 and the first telescopic sleeve 112 needs to be fixed, it is only necessary to screw the fixing bolt so that the fixing bolt is tightly pressed against the first telescopic sleeve 112, thereby achieving the relative position fixation of the first telescopic rod 111 and the first telescopic sleeve 112.

[0057] Optionally, the first sliding hole is a rectangular hole, and the first telescopic rod 111 is a rectangular rod adapted to fit within the first sliding hole. In this embodiment, this arrangement prevents the first telescopic rod 111 from rotating within the first sliding hole about the axis of the first sliding hole, so that the spacing between the two lower rectangular blocks 12 can only be adjusted along the first direction X, ensuring that the two lower reference surfaces 121 of one lower rectangular block 12 always correspond to and are parallel to the two lower reference surfaces 121 of the other lower rectangular block 12.

[0058] Optionally, the second telescopic member 21 includes a second telescopic rod 211, a second telescopic sleeve 212, and a second stopper 213. The second telescopic sleeve 212 is provided with a second sliding hole. The second telescopic rod 211 is inserted into the second sliding hole and slides with the second telescopic sleeve 212. The second telescopic rod 211 is fixedly connected to the corresponding upper rectangular block 22, and the second telescopic sleeve 212 is fixedly connected to the corresponding lower rectangular block 12. The second stopper 213 allows the second telescopic rod 211 and the second telescopic sleeve 212 to have two relative fixed and relative sliding states. In this embodiment, the second telescopic rod 211 slides within the second sliding hole, thereby adjusting the spacing between the upper rectangular block 22 and the lower rectangular block 12. When the spacing between the upper rectangular block 22 and the lower rectangular block 12 is adjusted, the second stopper 213 fixes the relative position of the second telescopic rod 211 and the second telescopic sleeve 212, thereby fixing the spacing between the upper rectangular block 22 and the lower rectangular block 12.

[0059] like Figure 3 As shown, optionally, the second limiting member 213 includes a second locking pin 215, a second limiting screw sleeve a216 and a second limiting screw sleeve b217, and the peripheral wall of the second telescopic sleeve 212 is provided with a second waist-shaped sliding hole 214 along the second direction Y, and the second waist-shaped sliding hole 214 is connected to the second sliding hole, and the second locking pin 215 is passed through the second waist-shaped sliding hole 214 and is fixedly connected to the second telescopic rod 211, and the outer peripheral wall of the second telescopic sleeve 212 is provided with an external thread, and the second limiting screw sleeve a216 and the second limiting screw sleeve b217 are respectively sleeved on the second telescopic sleeve 212 and respectively screwed to the second telescopic sleeve 212, and the second limiting screw sleeve a216 and the second limiting screw sleeve b217 are located on both sides of the second locking pin 215 along the second direction Y. In this embodiment, the second telescopic rod 211 slides in the second sliding hole, and then the second telescopic rod 211 drives the second locking pin 215 to slide in the second waist-shaped sliding hole 214. When the relative position of the second telescopic rod 211 and the second telescopic sleeve 212 is determined, the second limiting screw sleeve a216 and the second limiting screw sleeve b217 are screwed so that the second limiting screw sleeve a216 and the second limiting screw sleeve b217 clamp the second locking pin 215 along the second direction Y, thereby limiting the position of the second locking pin 215 in the second waist-shaped sliding hole 214, so that the relative position of the second telescopic rod 211 and the second telescopic sleeve 212 is fixed.

[0060] like Figure 2 As shown, in other embodiments, the second limiting member 213 includes a fixing bolt, which penetrates into the second waist-shaped sliding hole 214 and is screwed to the second telescopic rod 211. When the relative position of the second telescopic rod 211 and the second telescopic sleeve 212 needs to be fixed, it is only necessary to screw the fixing bolt so that the fixing bolt is pressed against the second telescopic sleeve 212, thereby achieving the relative position fixation of the second telescopic rod 211 and the second telescopic sleeve 212.

[0061] Optionally, the second sliding hole is a rectangular hole, and the second telescopic rod 211 is a rectangular rod adapted to fit within the second sliding hole. In this embodiment, this arrangement prevents the second telescopic rod 211 from rotating within the second sliding hole about its axis, thereby enabling the upper rectangular block 22 to adjust its spacing relative to the lower rectangular block 12 only along the first direction X. This ensures that the two lower reference surfaces 121 of a lower rectangular block 12 always correspond to and are parallel to the two upper reference surfaces 221 of the corresponding three rectangular blocks.

[0062] Optionally, both the lower corner plate 101 and the upper corner plate 102 are ferromagnetic, and both the lower rectangular block 12 and the upper rectangular block 22 are magnetic. In the embodiment, the lower clamping plate and the lower rectangular block 12 are magnetically attracted to each other, so that the two side walls of the lower corner plate 101 always conform to the two lower reference surfaces 121 of the lower rectangular block 12, and the upper clamping plate 102 and the upper rectangular block 22 are magnetically attracted to each other, so that the two side walls of the upper corner plate 102 always conform to the two upper reference surfaces 221 of the upper rectangular block 22. This arrangement eliminates the need for workers to manually hold the upper corner plate 102 or the lower corner plate 101, freeing up their hands and thereby improving their work efficiency.

[0063] In other embodiments, optionally, the lower corner plate 101 and the upper corner plate 102 are both non-magnetic parts, and the flaring device adjustment fixture further includes two ferromagnetic positioning lower corner plates 4 and two ferromagnetic positioning upper corner plates 5. The lower rectangular block 12 and the upper rectangular block 22 are both magnetic. The two ferromagnetic positioning lower corner plates 4 correspond one-to-one with the two lower corner plates 101. The ferromagnetic positioning lower corner plates 4 are arranged on the side of the lower corner plate 101 away from the lower rectangular block 12 and are magnetically attracted to the lower rectangular block 12; the two ferromagnetic positioning upper corner plates 5 correspond one-to-one with the two upper corner plates 102. The ferromagnetic positioning upper corner plates 5 are arranged on the side of the upper corner plate 102 away from the upper rectangular block 22 and are magnetically attracted to the upper rectangular block 22. In this embodiment, the lower corner plates 101 and the upper corner plates 102 are both non-magnetic parts. Therefore, the upper corner plates 102 cannot be magnetically attracted to the corresponding upper rectangular block 22, and the lower corner plates 101 cannot be magnetically attracted to the corresponding lower rectangular block 12. To free up workers' hands and improve their work efficiency, the flaring device adjustment fixture also includes two ferromagnetic positioning lower corner plates 4 and two ferromagnetic positioning upper corner plates 5. The two ferromagnetic positioning lower corner plates 4 are magnetically attracted to the two lower rectangular blocks 12 in a one-to-one correspondence, thereby pressing the two side surfaces of the lower corner plate 101 against the two lower reference surfaces 121 of the corresponding lower rectangular blocks 12. The two ferromagnetic positioning upper corner plates 5 are magnetically attracted to the two upper rectangular blocks 22 in a one-to-one correspondence, thereby pressing the two side surfaces of the lower upper corner plate 102 against the two upper reference surfaces 221 of the corresponding upper rectangular blocks 22. This arrangement also frees up workers' hands and improves their work efficiency.

[0064] Specifically, the ferromagnetic positioning lower corner plate 4 comprises an L-shaped first ferromagnetic plate and a second ferromagnetic plate. The first ferromagnetic plate and a lower reference surface 121 of the lower rectangular block 12 clamp one sidewall of the corresponding lower corner plate 101, while the second ferromagnetic plate and another lower reference surface 121 of the lower rectangular block 12 clamp the other sidewall of the corresponding lower corner plate 101. The structures of the ferromagnetic positioning upper corner plate 5 and the ferromagnetic positioning lower corner plate 4 are identical and will not be further described here.

Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
