Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a frame material picking mechanism, particularly a mattress frame material picking mechanism. Background Technology

[0002] To improve the stability of the mattress core, a metal frame is typically used for fixation. Corresponding automated equipment has been developed, such as the mattress core frame positioning device, method, and spring mattress production line disclosed in the Chinese Patent Database (application number: 202210967591.4). This device includes a positioning mechanism comprising a support platform, at least one fixing component, and at least one limiting component. The support platform supports the mattress core, and the limiting component is movably positioned relative to or away from the support platform to ensure the frame fits against the mattress core. The limiting component is movably configured to form a receiving station and a positioning station. The limiting component is adapted to... The material receiving station receives the frame; the limiting component is adapted to limit the frame at the positioning station; wherein the fixing component includes at least one nail gun and a drive assembly, the drive assembly being used to drive the nail gun to move; the bed core frame positioning device further includes a feeding mechanism and a frame picking mechanism; the feeding mechanism is used to store or transport the frame; the frame picking mechanism includes a gripping component and a transfer component, the transfer component being adapted to drive the gripping component to move and form a receiving station and an output station, the gripping component being adapted to receive the frame on the feeding mechanism at the receiving station, and the gripping component being adapted to transport the frame to the limiting component at the output station.

[0003] When the aforementioned bed core frame positioning device is in use, the frame is gripped by the gripping component and tilted in. Then, the frame is gradually switched to a horizontal state by the movement and swinging of the gripping component, and finally placed horizontally in the designated position. Since the frame state switching and output are carried out synchronously, this process requires high precision in the fit of each component, which greatly increases the design and assembly difficulty. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a mattress frame material handling mechanism that reduces design and assembly difficulty.

[0005] The objective of this utility model can be achieved through the following technical solution: A mattress frame material handling mechanism, comprising a frame and a material handling component for gripping or releasing the frame, characterized in that the frame is provided with a longitudinal beam and a lifting component for driving the longitudinal beam to rise and fall; a support frame is provided between the longitudinal beam and the material handling component, and the material handling component is mounted on the support frame; the support frame is hinged to the lower end of the longitudinal beam, and a driving mechanism is provided on the longitudinal beam to make the support frame swing back and forth, the swing angle of the support frame being 0 degrees to 90 degrees to switch the frame from a vertical state to a horizontal state.

[0006] In use, the frame is vertically suspended and fed in by the conveyor. After the material grabbing component grabs the frame, the drive mechanism moves to make the support frame swing and switch the frame to a horizontal state. Then the lifting component moves to move the frame down for output.

[0007] This material handling mechanism uses a drive mechanism to swing the support frame, switching the frame from a vertical to a horizontal state. Then, a lifting mechanism moves the frame horizontally downwards for output. This separates the frame state switching and frame output processes, effectively reducing the design and assembly requirements and simplifying the process.

[0008] In the aforementioned mattress frame material handling mechanism, the material gripping assembly includes a gripping unit one and two gripping units two. Gripping unit one is used to grip the top edge of the frame, and the two gripping units two are used to grip the two side edges of the frame respectively. This design enhances the strength and stability of the material gripping assembly when gripping the frame, ensuring more stable and precise frame state switching.

[0009] In the aforementioned mattress frame material handling mechanism, the material handling unit 1 is driven to move by a translation mechanism 1 mounted on a support frame, and the material handling unit 1 moves along the distribution direction of the top and bottom edges of the frame. The movement of the material handling unit 1 to change its position and height not only facilitates adjustment but also adapts to frames of different lengths, making it highly practical.

[0010] In the aforementioned mattress frame material handling mechanism, the second material-gripping unit is driven to move by the second translation mechanism mounted on the support frame, and the second material-gripping unit moves along the distribution direction of both sides of the frame. Moving the second material-gripping unit to change its horizontal position not only facilitates adjustment but also adapts to frames of different widths, thus improving its practicality.

[0011] In the aforementioned mattress frame material handling mechanism, the longitudinal beam is slidably connected to the frame, allowing the longitudinal beam to slide more smoothly.

[0012] In the aforementioned mattress frame material handling mechanism, the lifting assembly includes a rack vertically fixed to the longitudinal beam and a lifting motor fixed to the frame. A gear that meshes with the rack is fixed to the main shaft of the lifting motor. This design offers advantages such as simple structure and stable operation.

[0013] In the above-mentioned mattress frame material handling mechanism, the translation mechanism includes a base slidably mounted on a support frame and a translation motor fixed on the support frame. The material handling unit is mounted on the base, and the translation motor drives the base to translate through a transmission structure.

[0014] In the above-mentioned mattress frame material handling mechanism, there are two sets of translation mechanism 2, which are respectively set to correspond to the two material handling units 2, so as to independently control the movement of the two material handling units 2 to adapt to more frames of different shapes and sizes.

[0015] In the above-mentioned mattress frame material handling mechanism, the translation mechanism 2 includes a base 2 slidably disposed on the support frame and a translation motor 2 fixed on the support frame. The material handling unit 2 is disposed on the corresponding base 2, and the translation motor 2 drives the base 2 to translate through the transmission structure 2.

[0016] In the aforementioned mattress frame material handling mechanism, the drive mechanism includes a vertically arranged swing cylinder, the cylinder body of which is fixed on the longitudinal beam, and the piston rod of which is connected to the support frame.

[0017] Compared with existing technologies, this mattress frame material feeding mechanism has the following advantages:

[0018] 1. This material handling mechanism uses a drive mechanism to swing the support frame, switching the frame from a vertical to a horizontal state. The lifting mechanism then moves the frame horizontally downwards for output. This separates the frame state switching and frame output processes, effectively reducing the design and assembly requirements and simplifying the process.

[0019] 2. The first material gripping unit moves to change its height, and the second material gripping unit moves to change its horizontal position. This not only makes it easy to adjust, but also allows it to adapt to different sized frames, making it more practical. Attached Figure Description

Detailed Implementation

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] Example 1: As Figure 1 As shown, the mattress frame material handling mechanism includes a frame 1 and a material handling component for gripping or releasing the frame 2. In actual use, the frame 2 is set vertically and waits for the material handling component to grip it. When the frame 2 is set vertically, it is formed by the top edge, bottom edge, and two side edges.

[0028] Specifically

[0029] The frame 1 is equipped with a longitudinal beam 3 and a lifting assembly for driving the longitudinal beam 3 to rise and fall. A support frame 4 is provided between the longitudinal beam 3 and the material gripping assembly, and the material gripping assembly is mounted on the support frame 4. The support frame 4 is hinged to the lower end of the longitudinal beam 3, and the longitudinal beam 3 is equipped with a drive mechanism that causes the support frame 4 to swing back and forth. The swing angle of the support frame 4 is 0 degrees to 90 degrees so that the frame 2 can switch from a vertical state to a horizontal state.

[0030] In use, the frame 2 is vertically suspended and fed in by the conveyor. After the material grabbing component grabs the frame 2, the drive mechanism moves to make the support frame 4 swing to switch the frame 2 to a horizontal state. Then the lifting component moves to make the frame 2 move down for output.

[0031] This material handling mechanism uses a drive mechanism to swing the support frame 3, causing the frame 2 to switch from a vertical to a horizontal state. The lifting mechanism then moves the frame 2 horizontally downwards for output. This separates the frame 2 state switching and frame 2 output processes, effectively reducing the design and assembly requirements and simplifying the process.

[0032] In this embodiment,

[0033] like Figure 5 As shown, the support frame 4 is hinged to the longitudinal beam 3 via a horizontally arranged pivot 5, and the axis of the pivot 5 extends along the distribution direction of both sides of the frame 2. Preferably, there are two pivots 5 arranged side by side along the pivot 5 to enhance the connection strength and stability between the support frame 4 and the longitudinal beam 3.

[0034] The drive mechanism includes a vertically arranged swing cylinder 6, the cylinder body of which is fixed to the longitudinal beam 3, and the piston rod of the swing cylinder 6 is connected to the support frame 4. Of course, the drive mechanism can also be a hydraulic cylinder or an electric push rod.

[0035] The longitudinal beam 3 is slidably connected to the frame 1, allowing the longitudinal beam 3 to slide more smoothly. Preferably, the longitudinal beam 3 and the frame 1 are connected by a guide rail slider structure to form a sliding fit. Of course, it is also possible for the longitudinal beam 3 and the frame 1 to form a sliding fit through a groove guide block structure.

[0036] Among them, such as Figure 2 and Figure 4As shown, the guide rail slider structure is specifically assembled as follows: The frame 1 has a connecting sleeve 1a, which is fitted onto the longitudinal beam 3. The guide rail slider structure includes a linear guide rail 7 vertically fixed to the longitudinal beam 3 and a guide block mounted on the linear guide rail 7, with the guide block fixed to the inner wall of the connecting sleeve 1a. Preferably, at least one set of the above-mentioned guide rail slider structure is provided on each opposite side of the longitudinal beam 3 to make the longitudinal beam 3 more stable in lifting and lowering.

[0037] The lifting assembly includes a rack 8 vertically fixed on the longitudinal beam 3 and a lifting motor 9 fixed on the frame 1. A gear meshing with the rack 8 is fixed on the main shaft of the lifting motor 9. This design offers advantages such as simple structure and stable operation. Of course, the lifting assembly can also be a pneumatic cylinder or a hydraulic cylinder.

[0038] like Figure 2 and Figure 3 As shown, the material gripping assembly includes a first gripping unit and two second gripping units. The first gripping unit grips the top edge of the frame 2, and the two second gripping units grip the two side edges of the frame 2 respectively. This design enhances the strength and stability of the gripping assembly when gripping the frame 2, ensuring more stable and precise switching of the frame 2's state. Further, the first gripping unit is driven to move by a translation mechanism on the support frame 4, and moves along the distribution direction of the top and bottom edges of the frame 2. Moving the first gripping unit changes its height, facilitating adjustment and adapting to frame 2s of different lengths, thus improving practicality. The second gripping unit is driven to move by a translation mechanism on the support frame 4, and moves along the distribution direction of the two side edges of the frame 2. Moving the second gripping unit changes its horizontal position, facilitating adjustment and adapting to frame 2s of different widths, further enhancing practicality.

[0039] in,

[0040] The structures of gripping unit one and gripping unit two are basically the same, both including a support base 10, a gripper 11 disposed on the support base 10, and a translation cylinder 12 for driving the support base 10 to translate axially along the frame 2. The gripper 11 is used to grip the frame 2. The gripper 11 is an existing product, and preferably the type of gripper 11 is a pneumatic gripper 11.

[0041] The translation mechanism includes a base 13 slidably mounted on a support frame 4 and a translation motor 14 fixed on the support frame 4. The material gripping unit is mounted on the base 13, meaning that the cylinder body of the translation cylinder 12 of the material gripping unit is fixed on the base 13. The translation motor 14 drives the base 13 to translate via a transmission structure.

[0042] The translation mechanism has two sets, each corresponding to one of the two gripping units, to independently control the movement of the two gripping units and adapt to more frames 2 of different shapes and sizes. The translation mechanism includes a base 15 slidably mounted on the support frame 4 and a translation motor 16 fixed on the support frame 4. The gripping unit is mounted on the corresponding base 15, meaning that the cylinder body of the translation cylinder 12 of the gripping unit is fixed on the base 15. The translation motor 16 drives the base 15 to translate through the transmission structure.

[0043] In this embodiment, both base 13 and base 2 15 are slidably engaged with the support frame 4 via a guide rail slider structure. The transmission structure 1 and transmission structure 2 are basically the same, both being belt drive structures, and this transmission method is existing and will not be described in detail here.

[0044] In the actual product, there are two sets of material gripping units, distributed along the two sides of the frame 2. There are two sets of translation mechanisms, each corresponding to one of the two material gripping units. The frame 1 can slide along the axial direction of the frame to adjust its position.

[0045] Example 2: The structure and principle of Example 2 are basically the same as those of Example 1. The difference is that both transmission structure 1 and transmission structure 2 are gear and rack structures.

[0046] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
