Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a switching device, particularly a switching device for assembling a bed core. Background Technology

[0002] During mattress production, components such as the frame and spring mattress are nailed to the core using fasteners. To reduce manual labor, corresponding automated equipment has been developed, such as a mattress core frame positioning device, method, and spring mattress production line disclosed in the Chinese Patent Database (application number: 202210967591.4). The positioning mechanism includes 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 snugly 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 receive the frame at the receiving station and to limit the frame at the positioning station. The fixing component includes at least one nail gun and a drive assembly, which drives the nail gun. The mattress core frame positioning device also includes a flipping mechanism for flipping the mattress core so that its upper and lower surfaces are successively supported by the support platform.

[0003] In the aforementioned positioning device, the bed core is flipped by a flipping mechanism. However, when the bed core is flipped, the nailing process stops and waits for the bed core to flip before being fed back in. This greatly prolongs the processing time and results in poor efficiency. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a highly efficient switching device for bed core assembly.

[0005] The objective of this utility model can be achieved through the following technical solution: a switching device for assembling a bed core, comprising a base plate and a placement plate for horizontally supporting the bed core, the placement plate being provided with a clamp for pressing the bed core, the bed core having a horizontally set central axis, characterized in that a processing station and a flipping station are provided above the base plate in a left-right distributed manner, and a placement plate is horizontally provided on both the flipping station and the processing station, with the two placement plates positioned at different heights; the base plate is also provided with two driving mechanisms for driving the two placement plates to translate left and right respectively, and under the action of the driving mechanisms, the placement plates switch back and forth between the processing station and the flipping station; a flipping mechanism is provided next to the flipping station, the flipping mechanism consisting of a connecting component and a flipping component, the connecting component being used to lift or lower the bed core in the flipping station, and the flipping component being provided on the connecting component and flipping the lifted bed core 180 degrees around the central axis.

[0006] The system is equipped with a processing station and a flipping station arranged in a left-right configuration. The processing station is used for processing the mattress core, and the flipping station is used for flipping the mattress core. Each processing station and flipping station is equipped with a shelf, and the two shelves switch back and forth between the flipping station and the processing station under the action of the drive mechanism, so that the processing and flipping processes can be carried out continuously without interruption, thereby greatly improving the mattress production efficiency.

[0007] In the aforementioned bed core assembly switching device, the bottoms of the two placement plates are respectively fixedly connected to bracket one and bracket two, both of which are slidably connected to the base plate, and two drive mechanisms are respectively connected to bracket one and bracket two. This design facilitates design and installation.

[0008] In the aforementioned bed core assembly switching device, the connecting assembly includes a frame and a translation mechanism for driving the frame to move closer to or away from the flipping station. The frame is provided with a support plate, a clamping component for clamping the edge of the bed core, and a lifting mechanism for driving the support plate to rise and fall. The placement plate is provided with a clearance notch for the clamping component to extend into and clamp the bed core. The flipping assembly includes a rotating shaft horizontally disposed between the support plate and the clamping component, and the central axis of the rotating shaft is collinear with the aforementioned central axis. One end of the rotating shaft is fixedly connected to the clamping component, and the other end of the rotating shaft is rotatably disposed on the support plate. The support plate is also provided with a rotating mechanism for driving the rotating shaft to rotate.

[0009] The flipping process is as follows: First, the clamp releases the constraint on the bed core; then the frame moves to allow the clamping component to extend into the clearance notch and clamp the edge of the bed core; then the support plate moves up to allow the bed core to detach from the shelf; then the shaft rotates to flip the bed core 180 degrees; after the flipping is completed, the support plate moves down to reset so that the bed core falls back onto the shelf; finally, the frame resets so that the clamping component resets. The entire process can be performed completely automatically, with advantages such as stable operation and high degree of automation.

[0010] In the aforementioned bed core assembly switching device, there are two sets of flipping mechanisms, distributed on the front and rear sides of the flipping station. The number of clearance gaps and clamping components are the same, and their positions correspond one-to-one. Setting up two sets of flipping mechanisms arranged at the front and rear can enhance the stability of bed core flipping and ensure the stable operation of the switching device.

[0011] In the aforementioned bed core assembly switching device, the clamping component includes a U-shaped positioning frame and a pressure plate horizontally disposed within the positioning frame. The positioning frame includes an upper side wall and a lower side wall. A driving component for raising and lowering the pressure plate is fixed on the upper side wall, and a clamping opening for clamping the edge of the bed core is formed between the pressure plate and the lower side wall. The pressure plate is raised and lowered by the driving component to change the size of the clamping opening. This not only facilitates adjustment but also adapts to bed cores of different thicknesses, making it highly practical.

[0012] In the aforementioned switching device for bed core assembly, the support plate is slidably connected to the frame to improve the smoothness of the support plate's sliding and make the switching device operate more stably.

[0013] In the aforementioned bed core assembly switching device, the lifting mechanism includes a lifting motor and a rack vertically fixed on the frame. The lifting motor is fixed on the side of the support plate opposite to the clamping components, and a gear that meshes with the rack is fixed on the main shaft of the lifting motor. The lifting mechanism adopts a gear and rack structure, which has the advantages of simple structure, stable operation, and high transmission efficiency.

[0014] In the aforementioned bed core assembly switching device, the lower side wall, at the end furthest from the corresponding rotating shaft, slopes downward to form a guide wall, and the pressure plate is positioned between the corresponding guide wall and the corresponding rotating shaft. The guide wall serves as a guide, allowing the bed core edge to enter the clamping opening more smoothly, thereby further improving the working stability of the device.

[0015] In the aforementioned bed core assembly switching device, the drive mechanism includes a drive motor fixed on the base plate, and the drive motor is connected to bracket one or bracket two through a lead screw and nut transmission structure.

[0016] In the aforementioned bed core assembly switching device, the translation mechanism includes a base and a translation motor fixed on the base. The frame is slidably mounted on the base, and the translation motor drives the frame to translate through a transmission structure.

[0017] Compared with existing technologies, this bed core assembly switching device has the following advantages:

[0018] 1. Set up processing stations and flipping stations distributed on the left and right. The processing station is used for processing the mattress core, and the flipping station is used for flipping the mattress core. Each processing station and flipping station is equipped with a shelf. Under the action of the drive mechanism, the two shelves switch back and forth between the flipping station and the processing station, so that the processing and flipping processes can be carried out continuously without interruption, thereby greatly improving the mattress production efficiency.

[0019] 2. The pressure plate is raised and lowered by the driving component to change the size of the clamping opening. This not only makes it easy to adjust, but also adapts to bed cores of different thicknesses, making it highly practical. Attached Figure Description

[0024] 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.

[0025] Example 1: As Figure 1 As shown, the switching device for assembling the mattress core includes a base plate 1 and a support plate 2 for horizontally supporting the mattress core. In actual products, the mattress core is a semi-finished or finished component in the mattress manufacturing process. The mattress core is generally rectangular or square in shape and has a horizontally set central axis.

[0026] The shelf 2 is equipped with a clamp 3 for pressing down the bed core. The specific structure of the clamp 3 can be referred to in the Chinese Patent Database for a bed core frame positioning device, method and spring mattress production line (application number: 202210967591.4), which will not be described in detail here.

[0027] Specifically

[0028] like Figure 1 As shown, a processing station and a flipping station are arranged horizontally on the top of the base plate 1. Each of the flipping station and the processing station has a horizontally positioned shelf 2, with one shelf 2 at a higher position than the other. The base plate 1 also has two drive mechanisms for driving the two shelf 2 to move left and right respectively. Under the action of these drive mechanisms, both shelf 2 can switch back and forth between the processing station and the flipping station. A flipping mechanism is located beside the flipping station. The flipping mechanism consists of a connecting assembly and a flipping assembly. The connecting assembly is used to lift or lower the bed core in the flipping station, and the flipping assembly is mounted on the connecting assembly and flips the lifted bed core 180 degrees around the central axis.

[0029] The system is designed with a processing station and a flipping station arranged in a left-right configuration. The processing station is used for processing the mattress core, and the flipping station is used for flipping the mattress core. Each processing station and flipping station is equipped with a shelf 2. Under the action of the drive mechanism, both shelf 2 switch back and forth between the flipping station and the processing station, so that the processing and flipping processes can be carried out continuously without interruption, thereby greatly improving the mattress production efficiency.

[0030] In this embodiment,

[0031] The bottoms of the two shelf panels 2 are respectively fixedly connected to bracket 4 and bracket 5. Both bracket 4 and bracket 5 are slidably connected to the base plate 1, and two drive mechanisms are respectively connected to bracket 4 and bracket 5. This design facilitates design and installation. Preferably, both bracket 4 and bracket 5 are connected to the base plate 1 via a guide rail slider structure, which is a common existing technology and will not be described in detail here. Of course, it is also possible for both bracket 4 and bracket 5 to be slidably connected to the base plate 1 via a sliding guide block structure.

[0032] The drive mechanism includes a drive motor 17 fixed on the base plate 1, and the drive motor 17 is connected to bracket 4 or bracket 5 via a lead screw and nut transmission structure. Naturally, the drive mechanism can also be a cylinder, and the piston rods of the two cylinders are connected to bracket 4 and bracket 5.

[0033] The connection assembly structure is as follows: The connection assembly includes a frame 6 and a translation mechanism for driving the frame 6 to move closer to or away from the flipping station. The frame 6 is equipped with a support plate 7, a clamping component for clamping the edge of the bed core, and a lifting mechanism for driving the support plate 7 to rise and fall. A vertical clearance notch 2a is provided on the shelf 1 for the clamping component to extend into and clamp the bed core. In use, when the bed core is placed flat on the shelf 1, the clearance notch 2a is positioned directly opposite the bed core.

[0034] The flipping assembly structure is as follows: The flipping assembly includes a rotating shaft 8 horizontally disposed between the support plate 7 and the clamping component, and the central axis of the rotating shaft 8 is collinear with the aforementioned central axis. One end of the rotating shaft 8 is fixedly connected to the clamping component, and the other end of the rotating shaft 8 is rotatably disposed on the support plate 7, and the support plate 7 is also provided with a rotating mechanism for driving the rotating shaft 8 to rotate.

[0035] The flipping process is as follows: first, the clamp 3 releases the constraint on the bed core; then the frame 6 moves to allow the clamping component to extend into the clearance notch 2a and clamp the edge of the bed core; then the support plate 7 moves upward to allow the bed core to detach from the shelf 2; then the rotating shaft 8 rotates to flip the bed core 180 degrees; after the flipping is completed, the support plate 7 moves downward to reset so that the bed core falls back onto the shelf 2; finally, the frame 6 resets so that the clamping component is reset. The entire process can be carried out completely automatically, with advantages such as stable operation and high degree of automation.

[0036] To further explain, there are two sets of tilting mechanisms, located at the front and rear of the tilting station. The number of clearance gaps 2a and clamping components are the same, and their positions correspond one-to-one. Setting up two sets of tilting mechanisms at the front and rear enhances the stability of the bed core tilting and ensures the stable operation of the switching device.

[0037] in,

[0038] The rotating shaft 8 is supported on the support plate 7 by bearings, and the rotating mechanism is as follows: the rotating mechanism includes a rotary motor 9 fixed on the support plate 7, a driven wheel fixed on the rotating shaft 8, and a driving wheel fixed on the main shaft of the rotary motor 9, and the driving wheel and the driven wheel are connected by a belt. Of course, the rotary motor 9 can also be directly connected to the rotating shaft 8.

[0039] like Figure 2 and Figure 3 As shown, the clamping component structure is as follows: The clamping component includes a U-shaped positioning frame 10 and a pressure plate 11 horizontally disposed within the positioning frame 10. The positioning frame 10 includes an upper sidewall 10b and a lower sidewall 10a arranged side by side. A driving member 12 for driving the pressure plate 11 to rise and fall is fixed on the upper sidewall 10b, and a clamping opening for clamping the edge of the bed core is formed between the pressure plate 11 and the lower sidewall 10a. The pressure plate 11 rises and falls under the action of the driving member 12 to change the size of the clamping opening. This not only facilitates adjustment but also adapts to bed cores of different thicknesses, making it highly practical.

[0040] To further explain, the lower sidewall 10a, at the end furthest from the corresponding rotating shaft 8, slopes downward to form an inlet wall 10c, and the pressure plate 11 is positioned between the inlet wall 10c and the corresponding rotating shaft 8. The inlet wall 10c serves as a guide, allowing the edge of the bed core to enter the clamping opening more smoothly, thereby further improving the working stability of the device.

[0041] Furthermore, the driving component 12 is either a cylinder or an electric push rod, preferably a cylinder, and the cylinder piston rod is fixedly connected to the corresponding pressure plate 11. To further explain, the pressure plate 11 is slidably connected to the upper sidewall 10b via a guide sleeve and guide rod structure, improving the stability of the sliding of the pressure plate 11.

[0042] In the actual product, each positioning frame 10 is equipped with two pressure plates 11 to improve the stability of the bed core clamping. At this time, the number of driving components 12 and pressure plates 11 are the same and their positions correspond one-to-one.

[0043] The lifting mechanism is as follows: the support plate 7 is slidably connected to the frame 6 to improve the smoothness of the sliding of the support plate 7 and make the switching device operate more stably. Preferably, the support plate 7 is connected to the frame 6 using a guide rail slider structure. The lifting mechanism includes a lifting motor 13 and a rack 14 vertically fixed on the frame 6. The lifting motor 13 is fixed on the side of the support plate 7 opposite to the clamping component, and a gear that meshes with the rack 14 is fixed on the main shaft of the lifting motor 13. The lifting mechanism adopts a gear and rack 14 structure, which has the advantages of simple structure, stable operation, and high transmission efficiency.

[0044] Of course, the lifting mechanism can also be a cylinder, and the cylinder piston rod is fixedly connected to the support plate 7.

[0045] The translation mechanism is as follows: It includes a base 15 and a translation motor 16 fixed on the base 15. A frame 6 is slidably mounted on the base 15. The translation motor 16 drives the frame 6 to translate via a transmission structure. The frame 6 is slidably connected to the base 15 via a guide rail slider structure; the transmission structure is a lead screw and nut transmission structure.
