[0001] The present application relates to the field of container end plate production, and in particular to an end plate production line. Background Art

[0002] The end plate production line is used to produce the end plates of containers, and mainly includes a material preparation conveyor chain, a lengthening unit, a profiling unit, a width trimming unit, a stacking conveyor chain, etc.

[0003] The plates are placed on the material preparation conveyor chain, the lengthening unit cuts the plates to the designed length, the pressing unit bends the plates, the widening unit cuts the plates to the designed width, and the finished products are stacked on the stacking conveyor chain.

[0004] The various units of the production line are connected by conveyor chains, which makes the production line narrow and long, which is not conducive to the full utilization of the space in the workshop. Summary of the Invention

[0005] In order to improve space utilization in a workshop, the present application provides an end plate production line.

[0006] This application provides an end plate production line, which adopts the following technical solutions:

[0007] An end plate production line includes a material preparation conveyor chain, a lengthening unit, a forming unit, a width trimming unit, a stacking conveyor chain, a manipulator and an adsorption component.

[0008] At least one of the conveying direction of the material preparation conveyor chain, trimming unit, forming unit, width trimming unit, and stacking conveyor chain is parallel to the X direction.

[0009] At least one of the conveying directions of the material preparation conveyor chain, trimming unit, press unit, width trimming unit, and stacking conveyor chain is parallel to the Y direction, and the Y direction is not parallel to the X direction.

[0010] The manipulator is used to drive the adsorption component to move between the material preparation conveyor chain and the trimming unit, between the trimming unit and the pressing unit, between the pressing unit and the widening unit and / or between the widening unit and the stacking conveyor chain.

[0011] The adsorption component is used to adsorb the plate.

[0012] By adopting the above technical solution, the adsorption component adsorbs the plate, and the manipulator is used to drive the adsorption component and the plate to move, so that the movement direction of the plate is not limited to the conveying direction of the material preparation conveyor chain, the lengthening unit, the pressing unit, the widening unit, and the stacking conveyor chain. This is beneficial for arranging the material preparation conveyor chain, the lengthening unit, the pressing unit, the widening unit, and the stacking conveyor chain according to the space in the workshop, which can improve the space utilization in the workshop.

[0013] Preferably, when the adsorption assembly is used to adsorb a single sheet on the top of a sheet stack, the adsorption assembly includes a lifting frame, a pulling member, a connecting frame and a suction cup.

[0014] The lifting frame is arranged horizontally and is used to be connected to the manipulator.

[0015] The upper end of the lifting member is used to connect to the lifting frame, and the lower end of the lifting member is used to connect to the connecting frame. There are multiple lifting members, and the vertical lengths of the multiple lifting members increase in sequence. The lifting members are made of soft materials.

[0016] The suction cup is connected to the lower end of the connecting frame,

[0017] When the connecting frame is in a horizontal state, the pulling force of at least one of the pulling members on the connecting frame is zero.

[0018] By adopting the above technical solution, the surface of the raw material plate is usually coated with processing oil (processing oil can provide lubrication and prevent cracking when bending the plate), and the processing oil allows the adjacent plates to be closely adsorbed;

[0019] The suction cup absorbs the top plate, and the lifting frame moves upward. The shortest pulling piece applies tension first, while the longest pulling piece does not apply tension, so that one end of the top plate is subjected to force, and the other end of the top plate is not subjected to force, which is conducive to the formation of a gap between one end of the top plate and the pile of plates below, and then breaking the surface with a point, which is conducive to the top plate being separated from the plate pile.

[0020] Preferably, the adsorption component further comprises:

[0021] The suction pump is connected to the suction pipe, and the suction cups are connected to the suction pipe;

[0022] The air pump is connected to an air supply pipe, and the suction cups are connected to the air supply pipe, which is located below the air extraction pipe;

[0023] Several switching cylinders correspond to the suction cups one by one, and the exhaust pipe and the air supply pipe are both connected to the interior of the switching cylinder. The interior of the switching cylinder is hollow and the lower end is open. The lower end of the switching cylinder is fixedly connected to the connecting frame. The suction cup includes a connecting pipe that is slidably connected to the connecting frame. The upper end of the connecting pipe extends into the corresponding switching cylinder. The connecting pipe is provided with an air hole that connects the inside and the outside. When the connecting pipe is in the highest state, the air hole is connected to the exhaust pipe. When the connecting pipe is in the lowest state, the air hole is connected to the air supply pipe.

[0024] By adopting the above technical solution, when the suction cup does not contact the plate, the suction cup is in the lowest state, and the air supply pipe supplies air to the suction cup through the switching cylinder and the connecting pipe. The gas in the suction cup is blown onto the plate, and then the processing oil at the position where the suction cup absorbs is blown away, thereby ensuring the suction effect of the suction cup on the plate; after the suction cup contacts the plate, the connecting pipe slides upward, and the air hole connects the connecting pipe with the exhaust pipe, so that negative pressure is generated inside the suction cup to suck the plate, thereby increasingly improving the stability of the suction cup's adsorption of the plate.

[0025] Preferably, the adsorption assembly further includes a guide rod and a pin.

[0026] The guide rod is connected to the lifting frame in a vertical sliding manner.

[0027] The pin is connected to the lower end of the guide rod, and the pin is arranged horizontally.

[0028] The connecting frame is provided with a pin hole, and the pin hole is used for the pin shaft to be embedded.

[0029] By adopting the above technical solution, the connecting frame can rotate around the pin shaft to achieve switching between tilt and horizontal of the connecting frame, and the guide rod is used to position the connecting frame, which is conducive to maintaining the position of the connecting frame stable, and thus stabilizing the position of the plate adsorbed by the adsorption assembly.

[0030] Preferably, the connecting frame is provided with a slide groove.

[0031] When the connecting frame is in a horizontal state, the extending direction of the sliding groove is horizontal.

[0032] There are two guide rods, and the pins are arranged corresponding to the guide rods.

[0033] The sliding groove is used for the pin shaft to be embedded and slide.

[0034] By adopting the above technical solution, the stability of the connecting frame is further improved.

[0035] Preferably, the axis of the pin hole is located directly below the lower end of the longest lifting member.

[0036] By adopting the above technical solution, the lifting frame moves downward, so that the connecting frame moves downward to approach the plate pile. The connection point between the connecting frame and the longest pulling member first contacts the plate, and then the connecting frame flips over at the contact point; the setting of the pin hole axis facilitates the flipping of the connecting frame.

[0037] Preferably, the adsorption assembly further comprises a heat source, and the heat source is used to heat the edges and / or corners of the plate.

[0038] By adopting the above technical solution, the edges and / or corners of the plate are heated by a heat source, so that the processing oil at the edges and corners of the plate evaporates / volatizes, which is conducive to creating a gap between the edges and corners of the plate and the plate pile below; and only the edges and corners of the plate are heated, and subsequently the edges and corners can be cut by a lengthening unit and / or a widthening unit, without affecting the production quality of the finished end plate.

[0039] Preferably, it also includes:

[0040] A hot air pipe, the hot air pipe is connected to the connecting frame, one end of the hot air pipe is connected to the air pump, and the other end of the hot air pipe is directed toward the edge / corner of the plate;

[0041] The heat source is used to heat the gas output by the hot air pipe.

[0042] By adopting the above technical solution, the air pump blows air into the air supply pipe while also blowing air into the hot air pipe. Under the action of the heat source, the hot air pipe blows hot air toward the edges / corners of the plate, thereby evaporating the processing oil at the edges / corners of the plate, quickly eliminating the adhesion of the plate, and the hot air is not likely to cause excessive damage to the plate, thereby ensuring the performance of the plate.

[0043] Preferably, the hot air pipe is a hose, and when the pulling member applies tension to the connecting frame, the pulling member squeezes and closes the hot air pipe.

[0044] By adopting the above technical solution, when the lifting frame drives the connecting frame to move upward and away from the plate pile, the pulling member applies a pulling force to the connecting frame. At this time, the pulling member squeezes the hot air pipe and closes the hot air pipe, quickly stops the air supply, and ensures the adsorption stability of the suction cup on the plate.

[0045] In summary, this application includes at least one of the following beneficial technical effects:

[0046] 1. The adsorption component adsorbs the plate, and the manipulator drives the adsorption component and the plate to move. This makes the plate movement direction not limited to the conveying direction of the material preparation conveyor chain, lengthening unit, pressing unit, width trimming unit, and stacking conveyor chain. This is conducive to the layout of the material preparation conveyor chain, lengthening unit, pressing unit, width trimming unit, and stacking conveyor chain according to the space in the workshop, which can improve the space utilization in the workshop;

[0047] 2. The suction cup absorbs the top sheet and the lifting frame moves upward. The shortest lifting piece applies tension first, while the longest lifting piece does not. This causes one end of the top sheet to be stressed while the other end is unstressed. This helps to create a gap between one end of the top sheet and the stack of sheets below, thus breaking the gap and facilitating the top sheet to separate from the stack.

[0048] 3. Use a heat source to heat the edges and / or corners of the plate, so that the processing oil at the edges and corners of the plate evaporates / volatizes, which is conducive to creating a gap between the edges and corners of the plate and the plate stack below.

[0055] The following is combined with Figure 1-4 This application is described in further detail.

[0056] Reference Figure 1 The embodiment of the present application discloses an end plate production line, including a material preparation conveyor chain 11, a lengthening unit 12, a press unit 13, a widening unit 14, a stacking conveyor chain 15, a robot 16 and an adsorption component 2.

[0057] The stock preparation conveyor chain 11 transports the raw material stack. The lengthening unit 12 cuts the sheets to the designed length. The profiling unit 13 bends the sheets. The widening unit 14 cuts the sheets to the designed width. The finished end sheets are stacked onto the stacking conveyor chain 15, which then unloads the stack.

[0058] At least one of the conveying directions of the material preparation conveyor chain 11, trimming unit 12, press unit 13, width trimming unit 14, and stacking conveyor chain 15 is parallel to the X direction. At least one of the conveying directions of the material preparation conveyor chain 11, trimming unit 12, press unit 13, width trimming unit 14, and stacking conveyor chain 15 is parallel to the Y direction. The Y direction is not parallel to the X direction.

[0059] This embodiment is attached Figure 1 Middle: Y direction is perpendicular to X direction; the conveying direction of the material preparation conveyor chain 11, the lengthening unit 12, and the stacking conveyor chain 15 are all in the Y direction, and the material preparation conveyor chain 11, the lengthening unit 12, and the stacking conveyor chain 15 are distributed along the X direction (the conveyor chain of the lengthening unit 12 is not connected to the material preparation conveyor chain 11, the two are adjacent and parallel); the conveying direction of the pressing unit 13 is in the X direction.

[0060] The suction assembly 2 is used to suction the sheet material. The manipulator 16 is used to drive the suction assembly 2 to move between the material preparation conveyor chain 11 and the trimming unit 12, between the trimming unit 12 and the pressing unit 13, between the pressing unit 13 and the widening unit 14, and / or between the widening unit 14 and the stacking conveyor chain 15.

[0061] This embodiment is attached Figure 1 Middle: There are three manipulators 16; a truss-type manipulator 16 is set between the material preparation conveyor chain 11 and the lengthening unit 12, a truss-type manipulator 16 is set between the lengthening unit 12 and the pressing unit 13, and a multi-axis manipulator 16 is set between the pressing unit 13, the widening unit 14 and the stacking conveyor chain 15; the multi-axis manipulator 16 has a rotating base.

[0062] Reference Figure 1 and Figure 2 The adsorption component 2 at the truss-type manipulator 16 between the material preparation conveyor chain 11 and the elongation unit 12 is used to adsorb the single sheet on the top of the sheet stack;

[0063] Reference Figure 2 and Figure 3 The adsorption assembly 2 includes a lifting frame 21, a pulling member 22 and a connecting frame 23.

[0064] The lifting frame 21 is connected to the truss manipulator 16. The lifting frame 21 is arranged horizontally. The upper end of the pulling member 22 is used to be connected to the lifting frame 21. The lower end of the pulling member 22 is used to be connected to the connecting frame 23. There are multiple pulling members 22, and the vertical lengths of the multiple pulling members 22 increase successively.

[0065] Specifically: all lifting members 22 are divided into N groups, each group includes M lifting members 22; the N groups of lifting members 22 are distributed horizontally, and the M lifting members 22 in each group are distributed vertically, that is, all lifting members 22 are in a rectangular array; the vertical lengths of the M lifting members 22 in each group increase successively.

[0066] In this embodiment: N=1; in other embodiments: N may also be 2, 3, 5, etc.

[0067] The lifting member 22 is made of soft material, such as a soft rope or a steel cable. In this embodiment, the lifting member 22 is preferably a steel cable, the upper end of the steel cable is fixedly connected to the lifting frame 21, and the lower end of the steel cable is fixedly connected to the connecting frame 23. The length of the steel cable is the vertical length of the lifting member 22.

[0068] The adsorption assembly 2 also includes a suction cup 24. There are multiple suction cups 24, and the suction cups 24 are connected to the lower end of the connecting frame 23. All suction cups 24 are in a rectangular array. All suction cups 24 are divided into multiple groups, and the distribution direction of the multiple groups of suction cups 24 is parallel to the distribution direction of the multiple pulling members 22. The number of the multiple groups of suction cups 24 is consistent with the number of flexible tubes, that is, each flexible tube is connected to a group of suction cups 24. The number of pulling members 22 is consistent with the number of flexible tubes and corresponds one to one. When all the suction cups 24 are in contact with the plate, the connecting frame 23 is in a horizontal state, and the pulling force of at least one pulling member 22 on the connecting frame 23 is zero.

[0069] In this embodiment, when the connecting frame 23 is in a horizontal state, the pulling force of all the pulling members 22 on the connecting frame 23 is zero, that is, all the steel cables are in a relaxed state.

[0070] Reference Figure 3 and Figure 4 The adsorption assembly 2 also includes a guide rod 25 and a pin 26.

[0071] The guide rod 25 is vertically slidably connected to the lifting frame 21. Specifically, the lifting frame 21 is provided with a guide hole, which vertically penetrates the lifting frame 21; the upper end of the guide rod 25 is slidably embedded in the guide hole; preferably, the guide rod 25 is a rectangular parallelepiped; there are multiple guide rods 25, such as two, three or more guide rods 25.

[0072] The pin 26 is connected to the lower end of the guide rod 25 . The pin 26 is horizontally arranged and parallel to the horizontal direction.

[0073] The connecting frame 23 is provided with a mounting hole 231 , a pin hole 232 and a sliding slot 233 .

[0074] The number of mounting holes 231 corresponds to the number of guide rods 25. The mounting holes 231 vertically penetrate the connecting frame 23, and the lower end of the guide rod 25 is embedded in the mounting holes 231. The mounting holes 231 are parallel to the horizontal side walls to avoid the guide rod 25; preferably, the mounting holes 231 are parallel to the longitudinal side walls to slide and fit the guide rod 25.

[0075] The pin hole 232 is provided at a side wall of the mounting hole 231 parallel to the longitudinal direction, and the pin shaft 26 is coaxially rotatably embedded in the pin hole 232 .

[0076] In this embodiment, the axis of the pin hole 232 is located directly below the lower end of the longest lifting member 22; that is, when the longest steel cable is in a taut state, the axis of the pin hole 232 is coplanar with the axis of the longest steel cable.

[0077] The slide groove 233 is provided on the side wall of the other mounting holes 231 parallel to the longitudinal direction. The extending direction of the slide groove 233 is parallel to the connecting frame 23 . The slide groove 233 is used for the pin shaft 26 to be embedded and slide.

[0078] Reference Figure 3 and Figure 5 The adsorption component 2 also includes: an air suction pump (not shown in the figure) and an air blowing pump (not shown in the figure). The air blowing pump is connected to the air supply pipe 28. The suction cups 24 are all connected to the air supply pipe 28. The connecting frame 23 is fixedly connected to a plurality of switching cylinders 234 corresponding to the suction cups 24 one by one. The switching cylinder 234 is hollow inside. The suction cup 24 includes a connecting pipe 241 extending into the switching cylinder 234 and slidably connected to the connecting frame 23. The upper end of the switching cylinder 234 is closed. The connecting pipe 241 slides in the switching cylinder 234 to change the height of the suction cup 24.

[0079] Reference Figure 3 and Figure 5 The air supply pipe 28 is connected to the side of the switching cylinder 234. When the connecting frame 23 descends and approaches the plate, the air pump blows air into the switching cylinder 234 through the air supply pipe 28. A sealing ring can be installed on the outside of the connecting pipe 241 and the inside of the switching cylinder 234 to reduce gas leakage. An air hole 242 is opened on the side of the connecting pipe 241. The gas blown into the switching cylinder 234 enters the connecting pipe 241 through the air hole 242, and finally blows from the suction cup 24 to the surface of the plate, blowing away the processing oil at the place where the plate is about to be adsorbed by the suction cup 24, thereby reducing the influence of the processing oil on the adsorption effect after adsorption by the suction cup 24.

[0080] Reference Figure 3 and Figure 5 As the connecting frame 23 descends, the suction cup 24 at the lower end of the connecting frame 23 abuts against the plate, and the connecting pipe 241 slides upward, causing the air hole 242 to disconnect from the air supply pipe 28. The suction pump is connected to the exhaust pipe 27, and the air supply pipe 28 is located below the exhaust pipe 27. The exhaust pipe 27 is also connected to the switching cylinder 234. After the suction cup 24 rises to the highest position, the air hole 242 is connected to the exhaust pipe 27. At this time, the suction pump creates a negative pressure in the suction cup 24 through the exhaust pipe 27, thereby sucking the plate. As the connecting frame 23 continues to descend, the suction cups 24 at different positions successively contact and adsorb the plate. Both the exhaust pipe 27 and the air supply pipe 28 are flexible pipes to facilitate the movement of the connecting frame 23.

[0081] Reference Figure 3 and Figure 5The lifting frame 23 is equipped with a hot air pipe 29, which is a hose. The hot air pipe 29 is connected to the air pump. When the suction cup 24 contacts the plate, the air pump blows air into the suction cup 24 and into the hot air pipe 29 at the same time. A heat source (not shown in the figure) is installed outside the hot air pipe 29. The heat source uses an electric heating wire. Under the action of the electric heating wire, the hot air pipe 29 blows hot air outward. In this embodiment, the outlet of the hot air pipe 29 is directly above the edge / corner of the plate, thereby heating the edge and corner, and reducing the adhesion of the plate due to processing oil.

[0082] Reference Figure 5 After the plate is lifted, the suction pump keeps working, and then uses the negative pressure of the suction pipe 27 to limit the downward movement of the suction cup 24, ensuring the adsorption effect of the plate and realizing the smooth transfer of the plate. The suction pump can be a double-acting air pump, which switches to the inflation state after the plate is lowered to help the suction cup 24 return to its original position.

[0083] Reference Figure 3 When the lifting member 22 applies tension to the connecting frame 23, it squeezes the hot air pipe 29, closing it and quickly stopping the air blowing on the sheet surface, ensuring stable suction of the sheet by the suction cup 24. The two shortest steel cables are arranged side by side, and when they are taut, they fit together. The hot air pipe 29 passes between the two shortest steel cables. When the two shortest steel cables apply tension to the connecting frame 23, they clamp the hot air pipe 29, closing it.

[0084] In another embodiment, the outlet of the hot air pipe 29 is facing the side of the edge / corner of the plate and is located on the side where the plate is first lifted by the connecting frame 23. It plays the role of evaporating the heating oil on the surface of the plate. After one end of the plate is lifted, the hot air blows between the two plates, using the airflow to quickly release the adhesion between the plates.

[0085] The implementation principle of an end plate production line in an embodiment of the present application is: the adsorption component 2 adsorbs the plate, and the manipulator 16 is used to drive the adsorption component 2 and the plate to move, so that the movement direction of the plate is not limited to the conveying direction of the material preparation conveyor chain 11, the lengthening unit 12, the pressing unit 13, the widening unit 14, and the stacking conveyor chain 15, which is beneficial for arranging the material preparation conveyor chain 11, the lengthening unit 12, the pressing unit 13, the widening unit 14, and the stacking conveyor chain 15 according to the space in the workshop, and can improve the space utilization in the workshop.

[0086] The heat source is used to heat the edges and / or corners of the plate, so that the processing oil at the edges and corners of the plate evaporates / volatizes, which is conducive to the formation of a gap between the edges and corners of the plate and the plate pile below; the suction cup 24 absorbs the top plate, and the lifting frame 21 moves up, then the shortest pulling member 22 applies tension first, while the longest pulling member 22 does not apply tension, so that one end of the top plate is subjected to force, and the other end of the top plate is not subjected to force, which is conducive to the formation of a gap between one end of the top plate and the plate pile below, and then breaking the surface with a point, which is conducive to the top plate being separated from the plate pile.

[0087] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
