Description

Technical Field

[0001] The present invention relates to the field of mattress processing, and more specifically, to a fully automatic mattress skirting production process based on a handle and skirting integrated machine. Background Art

[0002] During the mattress production process, labels, trademarks, and handles need to be sewn onto the mattress skirts before they are sewn onto the mattress. The labels are used to mark information such as the material of the mattress or skirts, and the handles are used to facilitate gripping when transporting the mattress.

[0003] Patent document CN 113957619 A discloses a device for cutting and sewing mattress skirt strips with labeling, locking edges, and labeling. When processing mattress skirt strips, only locking edges and labeling can be performed. Because sewing mattress skirt strip labels is different from sewing trademarks and handles, the labels, trademarks, and handles cannot be completed in a single process. Sewing is done separately in multiple processes, resulting in a cumbersome production process and low work efficiency.

[0004] The existing mattress side strip processing method is: multiple processes, multiple stations, and multiple manual operations. The fabric needs to be sewn in a straight line, sewn at the edge, labeled, sewn with handles, marked, measured in length, cut, and sewn to complete the processing of the mattress strip. The sewing of the label, trademark, and handle of the strip cannot be completed in one process, resulting in low work efficiency.

[0045] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0046] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0047] like Figure 1 As shown, the present invention provides a fully automatic mattress skirting production process based on a handle skirting integrated machine, comprising the following steps:

[0048] Step 100: The bar conveying device conveys the bar to the workbench, keeping the bar flat and in a taut state;

[0049] Step 200: After the strip has been conveyed to a set length, the strip conveying device stops, and the first sewing device sews the trademark to a designated position on the strip. Then, the second sewing device sews the handle and label to designated positions on the strip.

[0050] Step 300: The strip conveying device continues to convey the strips. When the strip length reaches the set total length, the strip splicing device cuts the strips.

[0051] In step 400 , the strip splicing device overlaps and aligns the front and rear ends of the strip, and then sews them together.

[0052] The working principle of the above technical solution is:

[0053] like Figure 11 、 12 As shown, the mattress strip processing is completed by the mattress strip handle automatic production line, which includes a strip pattern machine, a front and back double-head overlocking machine, an automatic trademark machine and a handle automatic overlocking machine. The strip pattern machine, the front and back double-head overlocking machine, the automatic trademark machine and the horizontal handle automatic overlocking machine are connected end to end in sequence.

[0054] The strip pattern machine is used to sew patterns on the surface of the strip to improve the ornamental value of the strip;

[0055] The double-head overlocking machine is used to overlock the two sides of the fencing strips;

[0056] The automatic trademark machine includes a first sewing device;

[0057] The handle automatic overlocking machine includes a second sewing device;

[0058] The trademark is sewn by an automatic trademark machine at the set position of the girth. The trademark is set on the side of the mattress, at the center of the height of the girth strip;

[0059] The handle and label are sewn to the set position of the surrounding strip by the handle automatic overlocking machine. The label is sewn to the upper edge of the surrounding strip. The handle is sewn symmetrically to the opposite sides of the mattress. They are symmetrically set and the height is set in the middle position of the surrounding strip height direction.

[0060] The strip conveying device conveys the strip onto the workbench, keeping it flat and taut. After the strip reaches the set length, the strip conveying device stops, and the first sewing device sews the trademark to the specified position of the strip. Then, the second sewing device sews the handle and label to the specified positions of the strip. The strip conveying device continues to convey the strip. After the strip reaches the set total length, the strip splicing device cuts the strip. The strip splicing device stacks and aligns the front and rear ends of the strip, and then sews them together.

[0061] The mattress handle production line is also called the handle and handle all-in-one machine, and the handle splicing device is set at the end of the all-in-one machine;

[0062] After the bar conveying device stops conveying the bar, it can move the front end of the bar backward for a distance, leaving room for the bar to move when the clamping mechanism clamps the bar and the handle moves according to the set path.

[0063] Beneficial effects of the above technical solution:

[0064] The fully automatic mattress skirt strip production process based on the handle and skirt strip integrated machine described in the present invention sequentially sews the mattress skirt strip trademark, label and handle on the skirt strip, then cuts the skirt strip at a set length, overlaps and aligns the front and rear ends of the skirt strip, and then sews the front and rear ends of the skirt strip together to complete the skirt strip sewing, which is highly efficient and saves labor.

[0065] In one embodiment, step 200 includes:

[0066] Step 210: The trademark machine grabs the trademark from the trademark box and transports the trademark to a designated position on the surrounding strip;

[0067] Step 220, pressing the trademark onto the surrounding strip;

[0068] Step 230: The first sewing device sews the trademark onto the banding according to a specified sewing path.

[0069] The working principle of the above technical solution is as follows: After the automatic trademark machine grabs the trademark in the trademark box, it transports the trademark to the position where the trademark is sewn on the surrounding strip. The pressing mechanism presses the trademark on the surrounding strip, and the trademark sewing machine head sews the trademark on the surrounding strip according to the set path;

[0070] The process of sewing the handle and label is similar to that of sewing the trademark.

[0071] The beneficial effects of the above technical solution are: the automatic trademark machine is used to automatically grab the trademark and transport it to the designated position of the surrounding strip, and the automatic sewing machine sews the trademark according to the designated path. The sewing path is consistent with the shape of the outer edge of the trademark and is a certain distance away from the outer edge of the trademark. Automatic sewing can not only improve production efficiency and reduce the use of manpower, but also avoid the risk of personal injury caused by manual operation.

[0072] In one embodiment, before the handle strip is sewn to the surrounding strip, the handle transfer mechanism 1 transfers the handle from the handle box 2 to the handle table 3, and then transfers it from the handle table 3 to a designated position on the surrounding strip.

[0073] The working principle of the above technical solution is: before the handle strip is sewn to the surrounding strip, the handle transfer mechanism 1 transfers the handle from the handle box 2 to the handle table 3, and then transfers it from the handle table 3 to the designated position on the surrounding strip.

[0074] The beneficial effects of the above technical solution are as follows: the handle box can store multiple handles, which is convenient for taking out the handles. The handles can be transferred from the handle box to the handle support table, which is convenient for the handle grabbing and conveying mechanism to grab and fold the handles.

[0075] In one embodiment, after the handle is placed on the handle platform 3, the two ends of the handle extend out of the two sides of the handle plate 33, and the first manipulator presses the portion of the handle located on the handle plate 33 against the handle plate 33. The second manipulator presses down the portion extending out of the handle plate 33 and folds it back under the handle plate 33, and then presses it on the lower surface of the handle plate 33.

[0076] The first manipulator and the second manipulator clamp the handle and remove the handle from the side of the handle plate 33, and then place the handle at a designated position on the fence.

[0077] The working principle of the above technical solution is: after the handle is placed on the handle platform 3, the two ends of the handle extend out of the two sides of the handle plate 33 respectively, the first manipulator presses the part of the handle located on the handle plate 33 onto the handle plate 33, and the second manipulator presses down the part extending out of the handle plate 33 and folds it back to the bottom of the handle plate 33, and then presses it on the lower surface of the handle plate 33; the first manipulator and the second manipulator clamp the handle and remove it from the side of the handle plate 33, and then place it in the designated position of the fence.

[0078] The beneficial effects of the above technical solution are: the handle strip is automatically folded with high folding efficiency, consistent folding length, and better appearance. After the folded handle is sewn, the unlocked edge of the handle is pressed into the handle to prevent the thread ends of the handle from falling off.

[0079] In one embodiment, after the handle is placed at a designated position on the fence, the clamping mechanism clamps the fence and the handle, the control mechanism controls the clamping mechanism to move along a set path, and the second sewing device sews the handle to the fence.

[0080] The working principle of the above technical solution is: the head of the second sewing device does not need to move. During the sewing process, the clamping mechanism clamps the surrounding strip and the handle and moves together, and the needle of the second sewing device sews the handle to the surrounding strip.

[0081] The beneficial effects of the above technical solution are: since the second sewing device includes a needle and a transmission device, the structure of the second sewing device is more complex and difficult to control than the clamping mechanism, and the mobile clamping mechanism has a simple structure and is easy to operate.

[0082] In one embodiment, a plurality of handles are sewn to designated positions of the strips.

[0083] The working principle of the above technical solution is that the handles for each mattress during transportation are symmetrically distributed on both sides of the mattress. During the process of sewing the surrounding strips, multiple handles are sewn to the designated positions of the surrounding strips. After the surrounding strips are sewn to the mattress, the handles can be used as handles when lifting the mattress.

[0084] After the fencing strips are sewn onto the mattress, the handles on both sides of the mattress are symmetrical, and the two handles on the same side are also symmetrical, so that the center of gravity is more stable when lifting the mattress.

[0085] The beneficial effects of the above technical solution are: multiple handles are sewn to designated positions of the surrounding strips respectively. During the mechanically controlled sewing process, the tensioning force on the surrounding strips is consistent, the deformation of the surrounding strips is consistent, the sewing position of the handles is more precise, people are more comfortable when lifting the mattress, and the center of gravity is more stable when lifting the mattress.

[0086] In one embodiment, step 400 includes:

[0087] Step 401, clamping the front end of the fence;

[0088] Step 402: After the length of the bar reaches a set length, the bar is flipped along a horizontal axis perpendicular to the forward direction of the bar, and the front end of the bar is rotated backward and overlapped with the rear end of the bar;

[0089] Step 403: Cut off the tail end of the band and sew it together with the front end of the band to form a ring.

[0090] The working principle of the above technical solution is: for continuously processed strips, when the previous strip is cut off, a clamping mechanism is used to clamp the front end of the strip conveyed from the workbench. After the strip on the workbench is sewn with the trademark, handle and label, the strip is conveyed to the tail end of the workbench. When the length of the strip reaches the required length of the mattress, the clamping mechanism flips the front end of the strip backward, aligns it with the rear end of the strip and stacks them together, and then cuts off the rear end of the strip. The front and rear ends of the stacked strips are clamped together and transferred to the position of the sewing machine, and the front and rear ends of the strips are sewn together to form a ring.

[0091] The beneficial effects of the above technical solution are: the strips are mechanically transmitted, the transmission force is consistent, the deformation of the strips is small, the length of the strips after cutting is more accurate, and after being sewn into a ring, the size error with the four sides of the mattress is smaller, which can reduce the waste of materials caused by size and make the appearance of the mattress more beautiful.

[0092] like Figure 3-4 As shown, in one embodiment, the handle box 2 includes a box body, and two sets of baffles are symmetrically arranged on the upper end surface of the bottom plate 21 of the box body, and the two sets of baffles form a space for accommodating the handle;

[0093] A symmetrically arranged support plate 22 is provided on the lower end surface of the base plate 21. A hydraulic motor 23 is provided at the lower end of the two support plates 22. The output shaft of the hydraulic motor 23 is connected to one end of a screw 24. The other end of the screw 24 is rotatably connected to the lower end surface of the base plate 21.

[0094] A nut 25 threadedly connected to the lead screw 24 is provided on the lead screw 24 . A slide plate 26 penetrating the bottom plate 21 and entering the middle of the baffle is provided on the nut 25 . A lifting plate 27 is provided on the upper end surface of the slide plate 26 .

[0095] The working principle of the above technical solution: two sets of baffles are symmetrically arranged around the upper end surface of the base plate, which can provide a position for stacking handles. A lifting plate is set on the base plate. After the handles on the upper layer are removed, the hydraulic motor rotates to drive the screw to rotate, so that the nut threadedly connected to the screw moves upward, pushing the slide to move upward, thereby pushing the lifting plate upward, so that the handles on the next layer reach the work station.

[0096] The beneficial effects of the above technical solution are: the baffle can prevent the handles from falling. After the handles on the upper layer are taken away, the lifting plate rises, allowing the handles on the next layer to reach the work station, and the handles stacked in the middle of the baffle are continuously raised, which can realize uninterrupted feeding of the handles and enable the sewing process of the handles to be carried out continuously.

[0097] In one embodiment, a guide column 28 is provided on the bottom surface of the lifting plate 27 , and a guide sleeve 29 is provided on the bottom plate 21 at a distance from the slide plate and passes through the bottom plate. The guide column 28 slides in the guide sleeve 29 .

[0098] The working principle of the above technical solution is: a guide column 28 is set on the bottom surface of the lifting plate, and a guide sleeve 29 is set on the lower end surface of the base plate 21. The guide sleeve passes through the base plate and is fixedly connected to the base plate. The guide column 28 is slidably connected to the guide sleeve 29. The guide sleeve 29 plays a guiding role when the guide column 28 moves up and down.

[0099] The beneficial effects of the above technical solution are: a guide sleeve is set on the bottom plate, a guide column is set in the guide sleeve, and the upper end of the guide column is connected to the lifting plate, which can ensure that the lifting plate 27 remains horizontal when it moves up and down, so that the handle remains horizontal, which is convenient for the handle transfer mechanism to grab.

[0100] like Figure 5As shown, in one embodiment, the handle transfer mechanism 1 includes a vertical plate 11, and a first hydraulic cylinder 12 and a slide rail 13 are fixedly connected on one side of the vertical plate 11. A connecting plate 14 is provided on the piston rod of the first hydraulic cylinder 12, and a second hydraulic cylinder 15 vertically arranged with the first hydraulic cylinder 12 is provided on the side of the connecting plate 14 away from the slide rail. A slider 16 is provided on the side of the connecting plate 14 opposite to the second hydraulic cylinder 15. The slider 16 is slidably connected to the slide rail 13, and a movable plate 17 is provided on the piston rod of the second hydraulic cylinder 15. A suction head 18 is provided on the lower end surface of the movable plate 17. The suction head 18 is used to suck up the handle and transfer it to the handle platform 3.

[0101] The working principle of the above technical solution is as follows: the handle transfer mechanism 1 includes a vertical plate 11, a first hydraulic cylinder 12 and a slide rail 13 are fixedly connected on one side of the vertical plate 11, a connecting plate 14 is provided on the piston rod of the first hydraulic cylinder 12, a second hydraulic cylinder 15 which is perpendicular to the first hydraulic cylinder 12 is provided on the side of the connecting plate 14 away from the slide rail, a slider 16 is provided on the side of the connecting plate 14 opposite to the second hydraulic cylinder 15, the slider 16 is slidably connected to the slide rail 13, a movable plate 17 is provided on the piston rod of the second hydraulic cylinder 15, and a suction head 18 is provided on the lower end surface of the movable plate 17, which is used to suck up the handle and transfer it to the handle platform 3;

[0102] Two suction heads 18 are spaced apart on the movable plate. When grabbing the handle, the two suction heads 18 respectively suck the handle near both ends.

[0103] The suction head 18 is a vacuum suction head, which can suck the handle onto the suction head.

[0104] The beneficial effect of the above technical solution is that when grabbing the handle, the two suction heads 18 respectively suck the handle near the two ends, so that the handle can be kept in a horizontal state and transferred to the handle support table, preventing the handle from deforming and causing inaccurate position when placed on the handle table.

[0105] like Figure 6-7 As shown, in one embodiment, the handle platform 3 includes a square frame-shaped support base, the upper end surface of the upper plate 31 of the support base is provided with a fixed block 32, two handle plates 33 are symmetrically provided on both sides of the fixed block 32, a pressure plate 34 is rotatably provided on the fixed block 32, a pressure block 35 is provided at the front end of the pressure plate 34, and the pressure block 35 is used to press the handle 100, and a third hydraulic cylinder 37 is rotatably provided on the lower plate 36 of the support base, and the piston rod of the third hydraulic cylinder 37 passes through the groove 38 on the upper plate 31 and is rotatably connected to the rear end of the pressure plate 34;

[0106] The two side plates 39 of the support base are L-shaped. A fourth hydraulic cylinder 40 is rotatably provided on the upper portion of the rear side of one side plate 39 of the support base. An L-shaped positioning plate 41 is rotatably provided on the upper portion of the front portion of the side plate between the two side plates 39. A connecting block 42 is provided on the lower end surface of the positioning plate 41 near the rear edge. The connecting block 42 is rotatably connected to the piston rod of the fourth hydraulic cylinder 40.

[0107] The front end of the handle plate extends out of the edge of the upper plate and is located above the L-shaped notch of the two side plates. The handle plate is used to place the handle strip. A long hole 43 is provided at the rear of the handle plate 33.

[0108] The distance between the outer edges of the two handle plates 33 is smaller than the length of the handle.

[0109] The working principle of the above technical solution is:

[0110] Since the handle needs to be folded and the handle box contains multiple handles stacked together, the handle cannot be taken out of the handle box and placed directly on the apron at one time. The handle needs to be placed on the rear handle table first to facilitate the robot to fold the handle and place it in the designated position of the rear apron.

[0111] After the handle transfer mechanism 1 grabs the handle, it is placed on the handle plate 33. At this time, the piston rod of the first hydraulic cylinder 37 is retracted, the pressure block 35 is lifted and maintains a certain horizontal distance from the handle. The piston rod of the fourth hydraulic cylinder is extended, and the vertical side of the positioning plate 41 is vertical. After the handle is placed on the two handle plates 33, the piston rod of the third hydraulic cylinder 37 is extended, causing the pressure plate 34 to rotate, and the pressure block 35 presses on the handle.

[0112] The two ends of the handle placed on the handle plate 33 extend out of the two side edges of the handle plate 33. At this time, the handle grasping and conveying mechanism can clamp the white edge of the handle on the handle plate 33. The folding method is to press down the manipulators on both sides of the handle plate respectively, and the manipulators on the outside of the handle plate will bend the part of the handle extending out of the handle plate 33 downward and fold it back to the lower part of the handle plate. The manipulators on the upper and lower sides of the handle plate 33 clamp the handle. At this time, the piston rod of the third hydraulic cylinder 37 is retracted, the pressure block 35 releases the handle, the piston rod of the fourth hydraulic cylinder 40 is retracted, and the vertical plate of the positioning plate 41 moves away from the handle. The manipulator clamping the handle moves away from the pressure block, completing the folding and clamping action of the handle, and then the handle is placed on the fence for suturing.

[0113] The beneficial effects of the above technical solution are: the handle is taken out of the handle box and placed on the handle table, and the two ends of the handle extend to the outside of the edge of the handle plate, which is convenient for the robot to fold the handle. The appearance of the handle after folding is more refined and beautiful, and it can prevent the thread ends of the handle from falling off, thereby improving the quality of the mattress and the service life of the handle.

[0114] In one embodiment, the handle box 2 , the handle transfer mechanism 1 and the handle platform 3 are all arranged on a workbench, and the handle box 2 is connected to the workbench via a connecting mechanism.

[0115] The working principle and beneficial effects of the above technical solution: the handle box 2, the handle transfer mechanism 1 and the handle table 3 are all arranged on the workbench, the handle box 2 is connected to the workbench through a connecting mechanism, and the handle box 2, the handle transfer mechanism 1 and the handle table 3 are arranged on the workbench as needed at a position that does not hinder the transportation and sewing operations of the strips, making the equipment more compact and reducing the occupied space.

[0116] like Figure 8-10 As shown, in one embodiment, the connecting mechanism includes a fixing plate 5 fixedly connected to the bottom plate 21 of the handle box 2, the fixing plates 5 are symmetrically arranged on both sides of the bottom plate 21, a spherical groove 6 is arranged at the center of the lower end surface of the fixing plate 5, the fixing plate 5 is arranged in the limiting groove 8 of the base 7, and a spherical protrusion 9 is arranged at the position of the upper end surface of the base corresponding to the groove 6, the spherical protrusion 9 is movably connected to the groove 6, and the base 7 is fixedly connected to the workbench.

[0117] The working principle of the above technical solution is as follows: although the lower end surface of the lifting plate 27 of the handle box 2 is provided with a guide column 28, and the guide column 28 slides on the guide sleeve 29 to ensure the levelness of the lifting plate 27, thereby ensuring the levelness of the handle placed on the lifting plate 27, but because the edges of the handle strips may curl when stacked, the top of the handle on the top layer cannot be kept level, and the movable plate 17 of the handle transfer mechanism 1 cannot be adjusted in the horizontal direction. This may cause the two suction heads 18 to be unable to simultaneously suck up both ends of the handle when the handle transfer mechanism 1 sucks the handle. Although the movable plate 17 is pressed down to compress the handle to a certain distance, there is still a situation where one of the two suction heads sucks the handle;

[0118] A connecting mechanism is provided between the bottom plate 21 of the handle box 2 and the workbench, the connecting mechanism including a fixing plate 5 fixedly connected to the bottom plate 21 of the handle box 2, the fixing plates 5 being symmetrically provided on both sides of the bottom plate 21, the center of the lower end surface of the fixing plate 5 being provided with a spherical groove 6, the fixing plate 5 being provided in a limiting groove 8 of the base 7, a spherical protrusion 9 being provided at a position on the upper end surface of the base corresponding to the groove 6, the spherical protrusion 9 being movably connected to the groove 6, and the base 7 being fixedly connected to the workbench;

[0119] When the movable plate 17 of the connecting mechanism moves downward to absorb the handle, the positions of the two ends of the handle are different. When the movable plate 17 moves downward, one of the suction heads 18 contacts the handle, while the other suction head 18 cannot contact the handle. The suction head in contact with the handle presses the handle downward, causing the bottom plate to rotate at a certain angle along the axis of the line connecting the centers of the two spherical protrusions 9, so that the handle contacts the suction head that is not in contact.

[0120] The beneficial effects of the above technical solution are: when the handles are stacked and curled, the suction head can still suck up the handles and keep the handles in a horizontal state to transfer them to the handle support table 2, preventing the handles from being sucked up from one side and causing them to be unable to be accurately placed on the handle table, and reducing the situation where the handles cannot be sewn continuously due to errors during handle suction.
