Description

Technical Field

[0001] This application relates to the field of packaging technology, and more specifically, to a packaging drum separation device. Background Technology

[0002] Plastic packaging drums, due to their excellent properties such as being unbreakable, rust-free, lightweight, and having excellent oil and strong corrosion resistance, are widely used for packaging hazardous materials requiring insulation, moisture protection, pressure resistance, and corrosion resistance. To save transport space, packaging drums are typically transported by stacking after processing. However, when it's time to use the drums to hold materials, they need to be separated. But because the drums are tightly bound together due to their own weight and friction during transport, considerable force is required to separate them. Furthermore, when the packaging drums are stacked high, manually removing them from the top is extremely inconvenient, affecting packing efficiency.

[0003] Therefore, how to improve the separation efficiency of stacked packaging barrels has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a packaging drum separation device to improve the separation efficiency of stacked packaging drums.

[0013] Optionally, in the above-mentioned packaging barrel separation device, the lower insert includes a second body and at least two second inserts. The second body is connected to the first mounting base. Each of the second inserts is arranged side by side and spaced apart on the second body and is used to fit against the separating surface of the second packaging barrel. Along the side-by-side direction of the second inserts, the extension length of the second insert located at the end is greater than the extension length of the second insert located in the middle position.

[0014] Optionally, in the above-mentioned packaging barrel separation device, the separating surface of the first packaging barrel is the lower edge of the skirt of the first packaging barrel, and the upper insert is arranged to avoid the sealing surface of the first packaging barrel; the separating surface of the second packaging barrel is the upper edge of the skirt of the second packaging barrel, and the lower insert is arranged to avoid the sealing surface of the second packaging barrel.

[0015] Alternatively, the dividing surface of the first packaging barrel is the upper edge of the skirt of the first packaging barrel, and the upper insert is arranged to avoid the sealing surface of the first packaging barrel; the dividing surface of the second packaging barrel is the lower edge of the skirt of the second packaging barrel, and the lower insert is arranged to avoid the sealing surface of the second packaging barrel.

[0016] Optionally, in the above-mentioned packaging barrel separation device, the surfaces of the upper insert and the lower insert facing each other are a first surface and a second surface, respectively. A limiting protrusion is provided on one of the first surface and the second surface. The limiting protrusion is used to directly or indirectly abut against the other of the first surface and the second surface to limit the extreme position of the upper insert in the direction of the lower insert.

[0017] Optionally, in the above-mentioned packaging barrel separation device, both separation mechanisms are mounted on the same second mounting base.

[0018] Optionally, in the above-mentioned packaging barrel separation device, the second mounting base is provided with a sliding guide rail extending along the first direction, and the first mounting base is provided with a sliding groove that slides in cooperation with the sliding guide rail.

[0019] Optionally, in the above-mentioned packaging barrel separation device, a second driving member is provided on the second mounting base, the output end of the second driving member is connected to a transmission gear, the transmission gear meshes with two parallel transmission racks, and the two transmission racks are respectively connected to the first mounting bases of the two separation mechanisms.

[0020] The packaging drum separation device provided in this application is used to separate at least two stacked packaging drums. Two adjacent packaging drums along the stacking direction in the drum stack are defined as the first packaging drum and the second packaging drum, respectively. The first packaging drum is the one to be separated from other packaging drums in the stack. The packaging drum separation device includes two separation mechanisms arranged opposite each other along a first direction. Each separation mechanism includes a first mounting base, a lower insert, an upper insert, and a first driving member. The first mounting base is movable along the first direction, allowing the two separation mechanisms to move towards or away from each other along the first direction. The lower insert is disposed on the first mounting base and is used to abut the separating surface of the second packaging drum. The upper insert is used to abut the separating surface of the first packaging drum. The separating surfaces of the first and second packaging drums are typically parallel and face each other. The first driving member is disposed on the first mounting base and is drively connected to the upper insert, driving the upper insert to move the first packaging drum away from the second packaging drum along a second direction, thereby achieving drum separation. The second direction is parallel to the stacking direction of the drum stack, and the first direction is typically perpendicular to the second direction.

[0021] During the bin-separation process, the first packaging bin to be separated and its adjacent second packaging bin are first moved to the bin-separation station. After being moved into place, the two first mounting bases move from their initial positions along the first direction toward each other until they reach the bin-separation position. At this time, along the second direction, the lower blade is positioned opposite the bin-separation surface of the second packaging bin, while the upper blade is positioned opposite the bin-separation surface of the first packaging bin. After the movement is completed, the first driving component can drive the upper blade to move the first packaging bin away from the second packaging bin by a preset distance along the second direction. At the same time, under the action of the lower blade, the position of the second packaging bin can be kept fixed, thereby achieving bin separation. After the upper blade has moved, the first packaging bin can be manually removed or automatically transported to the subsequent bin-using station by a robotic arm, conveying device, etc. After the first packaging bin is removed, the upper blade moves in the direction of the lower blade to reset, and at the same time, the two sets of first mounting bases move away from each other to their initial positions, waiting for the next bin-separation operation. The packaging drum separation device disclosed in this application can be used in conjunction with a drum stacking and feeding device to ensure that at least two packaging drums are always stacked at the drum separation station.

[0022] Compared with related technologies, the packaging barrel separation device provided in this application can realize automatic barrel separation, reduce the intensity of manual labor, greatly improve the barrel separation efficiency, and thus improve the packaging efficiency of materials.

[0040] The core of this application is to disclose a packaging barrel separation device to improve the separation efficiency of stacked packaging barrels.

[0041] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the utility model as described in the claims. It should be noted that, for ease of description, only the parts relevant to the utility model are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0042] Combination Figures 1-14 The packaging barrel separation device disclosed in this application is used to separate at least two packaging barrels arranged in a stack. For ease of understanding, two adjacent packaging barrels in the stack along the stacking direction are defined as the first packaging barrel 200 and the second packaging barrel 210, and the first packaging barrel 200 is the packaging barrel that is to be separated from other packaging barrels in the stack. The packaging barrel separation device includes two separation mechanisms 100 arranged opposite to each other along a first direction. The separation mechanism 100 includes a first mounting base 130, a lower insert 120, an upper insert 110 and a first driving member 150. The first mounting base 130 can move along the first direction so that the two separation mechanisms 100 can move towards or away from each other along the first direction. The lower insert 120 is disposed on the first mounting base 130 and is used to fit against the dividing surface of the second packaging barrel 210; the upper insert 110 is used to fit against the dividing surface of the first packaging barrel 200. The dividing surfaces of the first packaging barrel 200 and the second packaging barrel 210 are usually parallel and face each other; the first drive member 150 is disposed on the first mounting base 130 and is connected to the upper insert 110 for driving the upper insert 110 to move the first packaging barrel 200 away from the second packaging barrel 210 along the second direction, thereby realizing the dividing of barrels. The second direction is parallel to the stacking direction of the barrel stack, and the first direction is usually perpendicular to the second direction.

[0043] Combination Figures 3-5Define a barrel-separating station between two sets of separation mechanisms 100. The packaging barrel separation device disclosed in this application can separate stacks of packaging barrels at the barrel-separating station. Specifically, during the barrel-separating process, the first packaging barrel 200 to be separated and its adjacent second packaging barrel 210 are first moved to the barrel-separating station. After being moved into position, the two first mounting bases 130 move from their initial positions along a first direction toward each other until they reach the barrel-separating position. At this time, along a second direction, the lower insert 120 is arranged opposite to the barrel-separating surface of the second packaging barrel 210, while the upper insert 110 is arranged opposite to the barrel-separating surface of the first packaging barrel 200. After the movement is completed, the first driving member 1... The upper inserter 110 can drive the first packaging barrel 200 to move a preset distance away from the second packaging barrel 210 along the second direction. Simultaneously, under the action of the lower inserter 120, the position of the second packaging barrel 210 can be kept fixed, thus achieving barrel separation. After the upper inserter 110 has moved, the first packaging barrel 200 can be manually removed or automatically transported to the subsequent barrel-using station by a robotic arm, conveying device, etc. After the first packaging barrel 200 is removed, the upper inserter 110 moves in the direction of the lower inserter 120 to reset, and simultaneously the two sets of first mounting bases 130 move away from each other to their initial positions, awaiting the next barrel separation operation. The packaging barrel separation device disclosed in this application can be used in conjunction with a barrel stacking device to ensure that at least two stacked packaging barrels are always present at the barrel separation station.

[0044] Compared to the manual bin separation in the prior art, the packaging bin separation device disclosed in this application can achieve automatic bin separation, reducing the intensity of manual labor, greatly improving the bin separation efficiency, and thus improving the packaging efficiency of materials.

[0045] It should be noted that the packaging drum separation device disclosed in this application has two separation methods: top-side separation and bottom-side separation. Top-side separation refers to separating the packaging drum located at the top of the stack by inserting and removing the drums, while bottom-side separation refers to separating the packaging drum located at the bottom of the stack by inserting and removing the drums. In the top-side separation method, the upper insert 110 lifts and separates the first packaging drum 200, and the lower insert 120 fixes the second packaging drum 210 to prevent it from moving. In the bottom-side separation method, the upper insert 110 presses down and separates the first packaging drum 200, and the lower insert 120 prevents the second packaging drum 210 from moving. The stacked drums can be arranged downwards; the following description uses the case where the drum stack opening faces downwards and the top is separated as the specific separation method.

[0046] In a specific bin-sorting process, combined with Figures 10-13The bucket stack feeding device raises the bucket stack to the bucket separation station corresponding to the upper insert 110 and the lower insert 120. The two separation mechanisms 100 can move from the initial position to the bucket separation position. At this time, the lower insert 120 can apply downward pressure to fix the second packaging bucket 210, and the upper insert 110 can move upward and lift the first packaging bucket 200 until the first packaging bucket 200 and the second packaging bucket 210 are reliably separated. After the separation is completed, the first packaging bucket 200 is removed. At this time, the first driving member 150 drives the upper insert 110 to reset, and the first mounting base 130 can move to the initial position. Repeating the above actions can separate each packaging bucket on the bucket stack one by one.

[0047] It should be noted that in some embodiments, the openings of the stacked buckets may also be arranged in a horizontal or other direction, and this application does not limit this.

[0048] To ensure that the upper inserter 110 can move stably in the second direction, the separation mechanism 100 also includes at least one linear guide bearing, combined with... Figure 2 and Figure 4 The linear guide bearing includes a guide portion 160 and a bearing portion 161. The guide portion 160 has a shaft-like structure, and the bearing portion 161 has a bearing structure. The bearing portion 161 is disposed on the first mounting base 130. The guide portion 160 can pass through the bearing portion 161 and roll-fit with it. The guide portion 160 is also connected to the upper insert 110 and arranged along a second direction. When the first drive member 150 drives the upper insert 110 to move, the guide portion 160 moves synchronously relative to the bearing portion 161. For example, two linear guide bearings are typically arranged on the first mounting base 130, symmetrically arranged on both sides of the first drive member 150, to ensure the stability of the force on the upper insert 110 during movement and the reliability of the linear guide bearing guidance.

[0049] Combination Figure 5 An obstacle hole 121 can be made on the lower insert 120 for the guide part 160 to pass through.

[0050] Combination Figure 1 In some embodiments, the upper insert 110 includes a first body 111 and at least two first inserts 112. The first body 111 is driveably connected to a first drive member 150. The first inserts 112 are arranged side-by-side and spaced apart on the first body 111 and are used to fit against the dividing surface of the first packaging barrel 200. Figure 1The extension lengths of the multiple first inserts 112 can be different, and along the parallel direction of the first inserts, the extension length of the first insert 112 located at the end is greater than that of the first insert 112 located in the middle position. All the first inserts 112 are arranged in an arc shape to roughly match the circular shape of the first packaging barrel 200. Simultaneously, the end of the first insert 112 away from the first body 111 can be a beveled structure tangent to the outer wall of the first packaging barrel 200. The spacing between the first inserts 112 can reduce the total weight of the upper insert 110 and lower production costs without affecting the lifting of the first packaging barrel 200 by the upper insert 110.

[0051] The lower insert 120 includes a second body and at least two second inserts. The second body is connected to the first mounting base 130. The second inserts are arranged side-by-side and spaced apart on the second body, and are used to fit against the dividing surface of the second packaging drum 210. Figure 2 The extension lengths of the multiple second inserts can be different, and along the parallel direction of the second inserts, the extension length of the second inserts located at the ends is greater than that of the second inserts located in the middle, so that the second inserts as a whole have an arc-shaped structure adapted to the shape of the second packaging barrel 210, and the end of the second insert away from the second main body can be a bevel structure tangent to the outer wall of the second packaging barrel 210. The spacing between the various second inserts is used to reduce the total weight of the lower insert 120 and reduce production costs.

[0052] Specifically, in combination Figure 1 and Figure 2 The first main body 111 can be connected to the first driving member 150 by fixing screws 170, and can be fixed to the guide part 160 by locking parts 162 such as locking blocks and locking screws. The second main body can be connected to the first mounting base 130 by fixing screws 170, and further positioned by positioning pins 171.

[0053] Furthermore, the first insert 112 and the first body 111 can be an integral structure, and are manufactured by integral molding methods such as stamping and injection molding. The second insert and the second body can also be an integral structure, and are manufactured by integral molding methods such as stamping and injection molding.

[0054] To avoid damaging the sealing surface 203 of the packaging drum during the drum splitting process, the upper insert 110 and the lower insert 120 are arranged to avoid the sealing surface 203 of the packaging drum during the drum splitting process. For example, combined with Figures 6-7The dividing surface of the first packaging barrel 200 can be the lower edge 202 of the skirt of the first packaging barrel 200, while the upper blade 110 is arranged to avoid the sealing surface 203 of the first packaging barrel 200. The dividing surface of the second packaging barrel 210 can be the upper edge 201 of the skirt of the second packaging barrel 210, while the lower blade 120 is arranged to avoid the sealing surface 203 of the second packaging barrel 210. Alternatively, the dividing surface of the first packaging barrel 200 can be the upper edge 201 of the skirt of the first packaging barrel 200, and the upper blade 110 can avoid the sealing surface 203 of the first packaging barrel 200. The dividing surface of the second packaging barrel 210 can be the lower edge 202 of the skirt of the second packaging barrel 210, and the lower blade 120 can avoid the sealing surface 203 of the packaging barrel during the dividing process, so that the packaging barrel can be reliably sealed with the lid when used later. Furthermore, the sealing surface 203 of the packaging drum is usually a slope, while the upper edge 201 and lower edge 202 of the skirt are usually flat. Therefore, using the lower edge 202 and upper edge 201 of the skirt as the dividing surface can also ensure that the first packaging drum 200 can move stably and is not prone to slipping during the movement of the upper insert 110. Compared with... Figure 8 and Figure 9 The method of separating the containers via the sealing surface 203, as shown in the diagram, offers higher reliability. It should be noted that the "skirt" of the packaging container in this application mainly refers to the protruding structure located at the opening of the packaging container, which serves to strengthen the structure and assist in sealing. The specific shapes and structures of the packaging container and the skirt are existing technologies and will not be elaborated upon in this application.

[0055] In some embodiments disclosed in this application, the surfaces facing each other, the upper insert 110 and the lower insert 120, are defined as a first surface and a second surface, respectively. A limiting protrusion 113 is provided on one of the first and second surfaces. The limiting protrusion 113 is used to directly or indirectly abut against the other of the first and second surfaces to limit the extreme position of movement of the upper insert 110 in the direction of the lower insert 120. Simultaneously, along the second direction, the size of the limiting protrusion 113 is less than or equal to the minimum distance between the first packaging barrel 200 and the second packaging barrel 210 in a stacked state, ensuring that the upper insert 110 and the lower insert 120 can be inserted between the dividing surfaces of the first packaging barrel 200 and the second packaging barrel 210. For example, Figure 1 The diagram shows a technical solution in which a limiting protrusion 113 is provided on a first surface, and the limiting protrusion 113 is used to indirectly abut against a second surface through a locking member 162. The limiting protrusion 113 and the upper insert 110 can be integrally formed by injection molding or other methods.

[0056] In some embodiments, the two separation mechanisms 100 may be disposed on the same second mounting base, thereby facilitating assembly. Further, to ensure reliable sliding of the two separation mechanisms 100 on the second mounting base, a sliding guide rail extending along a first direction is provided on the second mounting base, and a sliding groove is provided on the first mounting base 130 to slide in cooperation with the sliding guide rail. The sliding guide rail may be one rail or two rails that slide in cooperation with the first mounting base 130 of each of the two separation mechanisms 100 respectively.

[0057] The two first mounting bases 130 described above can be driven by different second driving members to move between the initial position and the dispensing position, or they can be driven by the same second driving member to move between the initial position and the dispensing position. For example, combined with... Figure 14 Both first mounting bases 130 of the two separation mechanisms 100 are driven by the same second driving member. The output end of the second driving member is connected to a transmission gear 180, which meshes with two parallel transmission racks 181. The two transmission racks 181 are respectively connected to the first mounting bases 130 of the two separation mechanisms 100. When the second driving member is activated, the transmission gear 180 rotates, and the two transmission racks 181 move synchronously in opposite directions, thereby causing the two separation mechanisms 100 to move closer to or further apart.

[0058] In order to ensure that the first mounting bases 130 of the two separation mechanisms 100 can be arranged relative to each other in the first direction, and to reserve the aforementioned bucket-separating station between the two separation mechanisms 100, the first mounting base 130 can be connected to the transmission rack 181 through the alignment mounting block 182, and the relative position of the two first mounting bases 130 can be adjusted through the alignment mounting block 182.

[0059] Combination Figure 2 A cylinder mounting cylinder 140 is provided on the first mounting base 130. The first driving component 150 can be a cylinder and is disposed inside the cylinder mounting cylinder 140. An clearance opening is provided on the side wall of the cylinder mounting cylinder 140, and the air pipe connector 151 of the cylinder can be exposed through the clearance opening to connect to an air source. The second driving component can also be a cylinder or other driving structure.

[0060] The packaging barrel separation device disclosed in this application separates the barrels by inserting a double-layer blade, and the force-bearing position of the barrel separation is the non-critical skirt plane of the packaging barrel. By adjusting the moving distance of the upper blade 110, the success rate of barrel separation can be improved and the sealing surface 203 of the packaging barrel can be preserved without damaging it.
