Description

Technical Field

[0001] This utility model relates to the field of furniture production equipment technology, and in particular to a cushion coding nail device. Background Technology

[0002] Chair seat cushions typically use elastic materials like springs and foam to enhance comfort. These elastic materials are wrapped in fabric and a padding board. During cushion manufacturing, the elastic material needs to be pre-compressed and maintained at a certain pre-compression level. This allows the cushion to provide good elastic deformation while maintaining its overall shape during use. Currently, a nail gun is usually used to nail the edges of the fabric to the padding board. However, the nail gun has a limited number of staples, requiring frequent replenishment, resulting in low production efficiency for the seat cushions. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a seat cushion coding pin device that eliminates the need for frequent machine stoppages to replenish coding pins, thereby improving seat cushion production efficiency.

[0004] A seat cushion stapler according to an embodiment of the present invention includes a three-axis drive assembly, a base, a staple gun, a staple feed magazine, a linear drive mechanism, a push rod, and a staple guide rail.

The output end of the linear drive mechanism is connected to the push rod. The staple guide rail is provided with a staple guide groove. The staple inlet of the staple gun is located in one end of the staple guide groove. The staple feed magazine is used to store multiple stacked staple rows. The staple feed magazine is configured to feed the staple rows to the middle of the staple guide groove. The linear drive mechanism drives the push rod to move within the staple guide groove to push the staple rows in the middle of the staple guide groove into the staple inlet.

[0005] It has at least the following beneficial effects:

[0006] When it is necessary to replenish the nail gun with staples, the linear drive mechanism drives the push rod to move away from the nail inlet, so that the staple cartridge can deliver the staple row to the center of the guide groove. The linear drive mechanism then drives the push rod to move towards the nail inlet, pushing the staple row in the guide groove into the nail inlet, thus replenishing the nail gun with staples. This process can be repeated to quickly and in large quantities replenish the nail gun with staples, reducing the frequency of the entire seat cushion stapleping device stopping to replenish staples, which can help improve the efficiency of seat cushion stapleping and seat cushion production.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Reference Figure 1 and Figure 2 This utility model discloses a seat cushion coding and nailing device, including a three-axis drive group 1, a base 2, a nail gun 3, a nail feed magazine 4, a linear drive mechanism 5, a push rod 6, and a nail guide rail 7. The output end of the three-axis drive group 1 is connected to the base 2. The nail gun 3, the nail feed magazine 4, the linear drive mechanism 5, and the nail guide rail 7 are all connected to the base 2. The output end of the linear drive mechanism 5 is connected to the push rod 6. The three-axis drive group 1 is used to drive the base 2 to move in the front-back, left-right, and up-down directions, thereby driving the nail gun 3, the nail feed magazine 4, the linear drive mechanism 5, the push rod 6, and the nail guide rail 7 to move in the front-back, left-right, and up-down directions, that is, to move in three-dimensional space.

[0036] Reference Figure 3 and Figure 4 The guide rail 7 is provided with a guide groove 71; the nail inlet of the nail gun 3 is located inside one end of the guide groove 71; the nail magazine 4 is used to store multiple stacked nail blocks, and the nail magazine 4 is configured to deliver the nail blocks to the middle of the guide groove 71; the push rod 6 can enter and exit the guide groove 71, and the linear drive mechanism 5 drives the push rod 6 to move in the guide groove 71 to push the nail blocks in the middle of the guide groove 71 into the nail inlet.

[0037] Multiple staples are connected in a row to form a staple row. The staples are U-shaped and the staple row has a certain length. Multiple staple rows are placed in the staple supply chamber 4. The staple supply chamber 4 is used to feed the staple rows one by one to the middle of the staple guide groove 71. The staple rows in the staple guide groove 71 are directly opposite the nail inlet of the nail gun 3. The push rod 6, the staple guide groove 71 and the nail inlet are on the same straight line, so that the staple rows can enter the nail inlet when they move in the staple guide groove 71. Initially, the linear drive mechanism 5 drives the push rod 6 to move away from the nail inlet, so that the push rod 6 is at the other end of the guide nail groove 71. Then, the nail magazine 4 delivers a row of staples to the middle of the guide nail groove 71. This row of staples is between the push rod 6 and the nail inlet. Next, the linear drive mechanism 5 drives the push rod 6 to move towards the nail inlet, so that the push rod 6 abuts against the row of staples and pushes the row of staples into the nail inlet, thus supplying staples to the nail gun 3. The nail gun 3 can then nail the edge of the fabric to the pad, thereby obtaining the cushion. When it is necessary to replenish staples for the nail gun 3, the linear drive mechanism 5 again drives the push rod 6 to move away from the nail inlet, so that the nail magazine 4 delivers another row of staples to the middle of the guide nail groove 71. This process is repeated to quickly and in large quantities replenish staples for the nail gun 3, reducing the frequency of the entire cushion stapleping device stopping to replenish staples, which is beneficial to improving the efficiency of cushion stapleping and cushion production.

[0038] It is conceivable that different models of seat cushions may use different models of staples, meaning the staples will have different sizes, thus requiring different models of nail guns 3 to nail the cushions. For different models of staples, the applicable guide slots 71 have different sizes. The guide slots 71 are formed on the guide rails 7 rather than directly on the base 2, allowing for the replacement of different guide rails 7 to achieve different sizes of guide slots 71. This makes the seat cushion nailing device compatible with different nail guns 3, meeting the needs of different seat cushions for different types of staples.

[0039] Reference Figure 1 In some embodiments, the three-axis drive group 1 includes a front-to-back drive mechanism 11, a left-to-right drive mechanism 12, and a top-to-bottom drive mechanism 13, which are used to drive the base 2 to move in the front-to-back, left-to-right, and top-to-bottom directions, respectively.

[0040] The output end of the front and rear drive mechanism 11 can move in the front and rear direction. The output end of the front and rear drive mechanism 11 is connected to the left and right drive mechanism 12. The output end of the left and right drive mechanism 12 can move in the left and right direction. The output end of the left and right drive mechanism 12 is connected to the upper and lower drive mechanism 13. The output end of the upper and lower drive mechanism 13 can move in the upper and lower direction. The output end of the upper and lower drive mechanism 13 is connected to the base 2.

[0041] Reference Figures 1 to 4In some embodiments, the staple cartridge 4 includes a base plate 41 and a baffle 42 disposed on the base plate 41. The base plate 41 is connected to the base 2, and an outlet 411 is provided on the base plate 41. The baffle 42 forms a limiting cavity for limiting the staple rows. The guide slot 71, the outlet 411, and the limiting cavity are sequentially connected, and the length directions of the guide slot 71, the outlet 411, and the limiting cavity are the same in the horizontal plane. Multiple stacked staple rows are placed in the limiting cavity, and the staple rows can enter the guide slot 71 through the outlet 411.

[0042] Reference Figure 5 In some embodiments, the enclosure 42 includes multiple limiting rods 421 and / or multiple limiting plates 422, the lower ends of which are connected to the base plate 41. The limiting rods 421 and the limiting plates 422 are used to block the row of code nails in the horizontal direction.

[0043] In some embodiments, the upper ends of multiple limiting rods 421 and / or multiple limiting plates 422 are connected to stiffening plates 43. The stiffening plates 43 fix the upper ends of the multiple limiting rods 421 and / or multiple limiting plates 422 together, thereby fixing the upper ends of the multiple limiting rods 421 and / or multiple limiting plates 422 relatively. An inlet 431 is provided on the stiffening plate 43. The length direction of the inlet 431 is the same as the length direction of the limiting cavity in the horizontal plane. The inlet 431 is used to feed the material staples into the limiting cavity.

[0044] Reference Figure 5 In some embodiments, a positioning sensor 8 is provided on the positioning rod 421 or the positioning plate 422 in the area near the outlet 411. The positioning sensor 8 is used to detect the row of code pins in the positioning cavity. When there is no row of code pins in front of the positioning sensor 8, the positioning sensor 8 is triggered, and the number of code pins in the positioning cavity is reduced to a preset value, and code pins need to be replenished in the positioning cavity in time.

[0045] In some embodiments, the staple cartridge 4 also includes a staple pressing block 44, which is used to press down the uppermost row of staples in the limiting cavity, so that all the staples in the limiting cavity can smoothly pass through the outlet 411 and fall into the middle of the guide slot 71.

[0046] Reference Figure 5 In some embodiments, a guide rod 45 is provided on the base plate 41, and a nail-pressing block 44 is sleeved on the guide rod 45. The guide rod 45 serves to limit and guide the nail-pressing block 44. Multiple nail-pressing rods 441 are connected to the nail-pressing block 44. There are gaps between the multiple limiting rods 421, between the multiple limiting plates 422, or between the limiting rods 421 and the limiting plates 422. The nail-pressing rods 441 pass through the gaps and extend into the limiting cavity. The nail-pressing block 44 presses down on the uppermost row of nails in the limiting cavity through the nail-pressing rods 441.

[0047] The main bodies of the guide rod 45 and the nail clamping block 44 are located outside the enclosure 42, which avoids the main bodies of the guide rod 45 and the nail clamping block 44 occupying the space inside the limiting cavity, and also facilitates manual lifting of the nail clamping block 44. The nail clamping rod 441 and the nail clamping block 44 can be connected by a threaded structure, or a connecting hole can be provided on the nail clamping block 44, and the connecting hole between the nail clamping rod 441 and the nail clamping block 44 can be connected by an interference fit.

[0048] In some embodiments, the seat cushion coding device also includes a coil spring on the base plate 41. The traction end of the coil spring is connected to the nail pressing block 44. The coil spring pulls the nail pressing block 44 downward. The nail pressing block 44 is subjected to a downward elastic force, so that all the coding pin rows can overcome the resistance they encounter when falling, ensuring that all the coding pin rows in the limiting cavity can fall into the guide pin groove 71.

[0049] In this embodiment, the enclosure 42 includes four limiting rods 421 and two limiting plates 422. The two limiting plates 422 are distributed front to back, with two limiting rods 421 distributed to the left between the two limiting plates 422, and the other two limiting rods 421 distributed to the right between the two limiting plates 422. The four limiting rods 421 and the two limiting plates 422 form a limiting cavity, with gaps between adjacent limiting rods 421 and between the limiting rods 421 and the limiting plates 422. Rib plates 43 connect the four limiting rods 421 and the two limiting plates 422 together. A positioning sensor 8 is located at the lower end of one of the limiting plates 422 near the outlet 411. There are four pressure nail rods 441. One end of a coil spring is connected to the base plate 41, and the other end of the coil spring is a traction end, which is connected to the pressure nail block 44.

[0050] Reference Figure 3 and Figure 4 In some embodiments, the guide pin groove 71 includes two parallel guide grooves 711 for the two ends of the staples of the staple row to extend into. The opening of the guide groove 711 is provided with a guide slope, which guides the end of the staple into the guide groove 711.

[0051] The push rod 6 includes a connecting part and two parallel push pin parts 61. One end of the connecting part is connected to the two push pin parts 61, and the other end of the connecting part is connected to the output end of the linear drive mechanism 5. The two push pin parts 61 are respectively inserted into two guide grooves 711. The output end of the linear drive mechanism 5 drives the two push pin parts 61 to move in the two guide grooves respectively.

[0052] The base 2 has a mounting groove 21, and the guide rail 7 is located in the mounting groove 21 of the base 2. The side wall of the mounting groove 21 limits the guide rail 7. The upper surface of the base 2 and the lower surface of the base plate 41 are in contact, and the base plate 41 covers the mounting groove 21. Two guide grooves 711 are formed on the upper surface of the guide rail 7. The area of ​​the upper surface of the guide rail 7 between the two guide grooves 711 is lower than the other areas of the upper surface of the guide rail 7. This can prevent the middle part of the staple from abutting against the area of ​​the upper surface of the guide rail 7 between the two guide grooves 711, and ensure that both ends of the staple can be fully inserted into the two guide grooves 711 respectively.

[0053] It is conceivable that the linear drive mechanism 5, the front and rear drive mechanism 11, the left and right drive mechanism 12, and the up and down drive mechanism 13 can be cylinders, hydraulic cylinders, or lead screw moving pairs.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
