Description

Technical Field

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

[0002] YP18D case packer is an optomechanical and electrical integrated device for cigarette packaging, which realizes the automation of the whole process of collecting, stacking, packing and sealing of carton strips. It can improve the efficiency of packaging, and through automated operation, it can accurately and quickly place the items in the box according to the set arrangement and quantity.

[0003] The expansion device of the YP18D cartoning machine is mainly to facilitate the entry of products into the packaging box. It can expand the opening of the box. During the packing process, cigarette cartons can be loaded into the box accurately and efficiently, reducing the collision and jamming between cigarette cartons and the edge of the box.

[0004] The expansion device includes two lower corner plates arranged at intervals along a first direction, two upper corner plates arranged at intervals along the first direction, and a driving assembly, wherein the two upper corner plates are located above the two lower corner plates along a second direction, and the two upper corner plates and the two lower corner plates are arranged to form a rectangular guide channel. One end of the two lower corner plates and one end of the two upper corner plates are simultaneously inserted into the opening of the box, the two lower corner plates are located at the two lower corners of the box, and the two upper corner plates are located at the two upper corners of the box, and the driving assembly drives the two upper corner plates and the two lower corner plates to expand the opening of the box, so that the cigarette stack can enter the box through the guide channel. In this process, the driving assembly can adjust the relative positions of the two lower corner plates and the two upper corner plates and the deflection angles relative to the axis of the guide channel, so that the expansion device can be adapted to boxes of different models. In the process of the driving assembly synchronously driving the two lower corner plates and the two upper corner plates, it is necessary to ensure that the deflection angles of the upper corner plates and the lower corner plates relative to the axis of the guide channel are consistent.

[0005] After the drive assembly is repaired or has been working for a long time, the connection positions of the drive assembly with the upper corner plate and the lower corner plate will change, which will cause the deflection angles of the upper corner plate and the lower corner plate relative to the axis of the guide channel to be inconsistent, which will cause the cigarette box to get stuck or even wrinkled 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 corner plate, as well as the connection position relationship between the drive assembly and the lower corner plate, so that the deflection angles of the upper corner plate and the lower corner plate relative to the axis of the guide channel are consistent.

[0006] When adjusting the connection position relationship between the drive assembly and the upper or lower corner plate, in order to ensure that the deflection angle of each upper or lower corner plate relative to the axis of the guide channel is consistent, the staff needs to manually adjust the deflection angle between each upper corner plate and the axis of the guide channel to 0°, and the deflection angle between each lower corner plate and the axis of the guide channel to 0°, and then fix the connection position relationship between the drive assembly and the upper or lower corner plate. However, during the process of fixing the connection position relationship between the drive assembly and the upper or lower corner plate, it is difficult to keep the deflection angle between the upper or lower corner plate and the axis of the guide channel at 0° due to the shaking of the staff's hands, resulting in poor maintenance results.

[0043] Embodiments of the present invention are described in detail below, examples of which 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

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

[0045] After the drive assembly 104 is repaired or has been working for a long time, the connection positions of the drive assembly 104 with the upper corner plate 102 and the lower corner plate 101 will change, which will cause the deflection angles of the upper corner plate 102 and the lower corner plate 101 relative to the axis of the guide channel 103 to be inconsistent, which will cause the cigarette box to get stuck or even wrinkled 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, and 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 corresponding to the two upper angle plates 102, and the two upper adjustment plates 1041 are provided with upper waist-shaped holes 1042, and the locking bolts pass through the upper waist-shaped holes 1042 and are screwed with the corresponding upper angle plates 102. By adjusting the position of the locking bolt in the upper waist-shaped holes 1042, the deflection angle between the axis of the upper angle plate 102 and the guide channel 103 can be adjusted. The drive assembly 104 also includes two lower adjustment plates corresponding to the two lower angle plates 101, and the two lower adjustment plates are provided with lower waist-shaped holes. The locking bolts pass through the lower waist-shaped holes and are screwed with the corresponding lower angle plates 101. By adjusting the position of the locking bolt in the lower waist-shaped holes, the deflection angle between the axis of the lower angle plate 101 and the guide channel 103 can be adjusted. After the drive assembly 104 is repaired or the drive assembly 104 has been working for a long time, it is necessary to adjust the position of the locking bolt in the upper waist-shaped hole 1042 or the lower waist-shaped hole. The specific structure of the driving component 104 is prior art and will not be described in detail here.

[0047] When adjusting the connection position relationship between the driving assembly 104 and the upper corner plate 102 or the lower corner plate 101, in order to ensure that the deflection angles of each upper corner plate 102 and the lower corner plate 101 relative to the axis of the guide channel 103 are consistent, the staff needs to manually adjust the deflection angles of each upper corner plate 102 and the axis of the guide channel 103 to 0°, and the deflection angles of each lower corner plate 101 and the axis of the guide channel 103 to 0°, and then fix the connection position relationship between the driving assembly 104 and the upper corner plate 102, and the driving assembly 104 and the lower corner plate 101. However, due to the shaking of the staff's hands, it is difficult to keep the deflection angles of the upper corner plate 102 or the lower corner plate 101 and the axis of the guide channel 103 at 0°, resulting in poor maintenance results.

[0048] To solve the above problems, Figure 2 to Figure 4As shown, the present embodiment provides an expansion device adjustment fixture, which is used to be arranged in the guide channel 103 of the expansion device 100, and the expansion device 100 includes two lower corner plates 101 and two upper corner plates 102, and the two lower corner plates 101 and the two upper corner plates 102 are all L-shaped and surrounded by the guide channel 103; the expansion 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, and the two lower rectangular blocks 12 are respectively fixed at both ends of the first telescoping device 11 along the first direction X, and the first telescoping device 11 can be telescoping along the first direction X, and 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, and 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 devices 21 along the second direction Y, and the second telescoping devices 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, and the two adjacent side surfaces of the upper rectangular blocks 22 are used to fit with the two side surfaces of the corresponding upper corner plates 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 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 the length of the first telescopic member is adjusted to make the distance between the two surfaces of the two lower rectangular blocks 12 away from each other along the first direction X equal to a, and 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 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 driving 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 driving 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, and 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 on the two lower rectangular blocks 12 in a one-to-one correspondence, and the two surfaces of the lower rectangular block 12 and the corresponding lower corner plate 101 are attached to 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 on the two upper rectangular blocks 22 in a one-to-one correspondence, and the two surfaces of the upper rectangular block 22 and the corresponding upper corner plate 102 are attached to the upper reference surfaces 221, and 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 90 degrees, and the two adjacent lower reference surfaces 121 of the lower rectangular block 12 are respectively in contact with the first plate and the second plate. At this time, the first laser 13 emits two laser beams, and the two laser beams are respectively flush with the two lower reference surfaces 121 of the lower rectangular block 12. If the first plate and the second plate are respectively in contact 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 respectively in contact with the first plate and the second plate. If the first plate does not contact the corresponding lower reference surface 121, the corresponding laser beam will not be completely emitted from the guide channel 103 or will be spaced from the corresponding first plate; if the second plate does not contact the corresponding lower reference surface 121, the corresponding laser beam will not be completely emitted from the guide channel 103 or will be spaced 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, and the two laser heads respectively set two laser beams along the third direction Z. The second laser 23 includes two laser heads, and the two laser heads respectively set 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, and is in contact with the upper angle plate 102 and the lower angle plate 101, and is opposite to the laser exit hole of the first laser 13, and 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 angle 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, and when the first plate and the second plate of the lower angle plate 101 are respectively at an angle with 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 whether there is 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 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 close to 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 is 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 device 11 includes a first telescopic rod 111, a first telescopic sleeve 112 and a first stopper 113.

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 limit member 113 includes a fixing bolt, which penetrates into the first waist-shaped sliding hole 114 and is threadedly connected to the first telescopic rod 111. When the relative positions of the first telescopic rod 111 and the first telescopic sleeve 112 need to be fixed, it is only necessary to screw the fixing bolt so that the fixing bolt is pressed against the first telescopic sleeve 112, thereby achieving the relative position fixing 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 the first sliding hole.

[0058] Optionally, the second telescopic device 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, the second telescopic sleeve 212 is fixedly connected to the corresponding lower rectangular block 12, and the second stopper 213 enables the second telescopic rod 211 and the second telescopic sleeve 212 to have two states of relative fixedness and relative sliding. In this embodiment, the second telescopic rod 211 slides in the second sliding hole to adjust the spacing of the upper rectangular block 22 relative to the lower rectangular block 12. When the spacing of the upper rectangular block 22 relative to the lower rectangular block 12 is adjusted, the relative position of the second telescopic rod 211 and the second telescopic sleeve 212 is fixed by the second stopper 213, so that the spacing of the upper rectangular block 22 relative to the lower rectangular block 12 is fixed.

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 threadedly connected 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 fixing 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 the second sliding hole. In this embodiment, this arrangement can prevent the second telescopic rod 211 from rotating around the axis of the second sliding hole in the second sliding hole, so that the upper rectangular block 22 can only adjust the spacing relative to the lower rectangular block 12 along the first direction X, so that the two lower reference surfaces 121 of a lower rectangular block 12 always correspond to the two upper reference surfaces 221 of the corresponding three rectangular blocks and are arranged in parallel.

[0062] Optionally, the lower corner plate 101 and the upper corner plate 102 are both ferromagnetic parts, and the lower rectangular block 12 and the upper rectangular block 22 are both magnetic. In the embodiment, the lower clamping plate and the lower rectangular block 12 are magnetically attracted, so that the two side walls of the lower corner plate 101 are always in contact with 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, so that the two side walls of the upper corner plate 102 are always in contact with the two upper reference surfaces 221 of the upper rectangular block 22. The above arrangement does not require the staff to hold the upper corner plate 102 or the lower corner plate 101, freeing the hands of the staff and thus improving the work efficiency of the staff.

[0063] In other embodiments, optionally, the lower corner plate 101 and the upper corner plate 102 are both non-magnetic parts, and the expansion device adjustment fixture also includes two ferromagnetic positioning lower corner plates 4 and two ferromagnetic positioning upper corner plates 5.

Therefore, the upper corner plate 102 cannot be magnetically attracted to the corresponding upper rectangular block 22, and the lower corner plate 101 cannot be magnetically attracted to the corresponding lower rectangular block 12. In order to free the hands of the staff and improve the work efficiency of the staff, the expansion 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 correspond to the two lower rectangular blocks 12 in a one-to-one magnetic attraction, thereby pressing the two side surfaces of the lower corner plate 101 on the two lower reference surfaces 121 of the corresponding lower rectangular block 12, and the two ferromagnetic positioning upper corner plates 5 correspond to the two upper rectangular blocks 22 in a one-to-one magnetic attraction, thereby pressing the two side surfaces of the lower upper corner plate 102 on the two upper reference surfaces 221 of the corresponding upper rectangular block 22. This setting also frees the hands of the staff and improves the work efficiency of the staff.

[0064] Specifically, the ferromagnetic positioning lower corner plate 4 includes a first ferromagnetic plate and a second ferromagnetic plate in an L shape, the first ferromagnetic plate and a lower reference surface 121 of the lower rectangular block 12 clamp one side wall of the corresponding lower corner plate 101, and the second ferromagnetic plate and another lower reference surface 121 of the lower rectangular block 12 clamp the other side wall 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 the same, which will not be repeated here.
