Abstract
Description
Technical Field
[0001] This application relates to the field of bag spring technology, and in particular to a bag spring conveying mechanism and a bag spring machine. Background Technology
[0002] When bagged springs are packaged, the springs are compressed by the spring feeding assembly and fed into a cloth bag. The cloth bag and springs are then conveyed to the welding assembly, where a transverse weld is welded onto the cloth bag to seal the springs. During the process from when the compressed spring leaves the spring feeding assembly to before welding and packaging, it is prone to deformation, radial bending, and misalignment, leading to packaging difficulties. In related technologies, the welding assembly is equipped with a scraper that scrapes the compressed springs from the spring feeding assembly into the cloth bag before welding. While this method can prevent spring bending to some extent, when the springs are large, the scraper can easily pull on the non-woven fabric of the bag during the scraping process, causing spring deformation. This results in the bagged springs being bent even after welding and packaging, affecting the finished quality of the bagged spring string. Utility Model Content
[0003] To solve at least one of the above-mentioned technical problems, this application provides a bag spring conveying mechanism and a bag spring machine to prevent the springs from deforming and shifting in position in the bag before sealing. The technical solution adopted is as follows.
[0004] The bag spring conveying mechanism provided in this application includes a limiting conveying assembly, which includes a first driving assembly, a second driving assembly, and two limiting assemblies arranged at intervals along the vertical direction. Under the drive of the first driving assembly, the two limiting assemblies can reciprocate synchronously along the longitudinal direction. Under the drive of the second driving assembly, the two limiting assemblies can move closer to or further away from each other along the vertical direction. Each limiting assembly includes at least two pressure arms, which extend laterally and are arranged at intervals along the longitudinal direction. The pressure arms in the two limiting assemblies are paired. When the two limiting assemblies move closer to each other, two adjacent pressure arms in one limiting assembly and two corresponding pressure arms in the other limiting assembly form a limiting area for limiting the spring in the bag. The forward movement of the limiting assembly along the longitudinal direction allows the spring to move along the longitudinal direction.
[0005] In some embodiments of this application, the number of limiting conveying components is at least two, the limiting conveying components are distributed laterally at intervals on both sides of the bag, and the limiting components on both sides of the bag alternately move closer to each other, and the limiting conveying components on both sides of the bag alternately move the springs longitudinally.
[0006] In some embodiments of this application, the first drive components of the limiting conveying assemblies on both sides of the bag are connected by a transmission shaft, thereby being powered by the same power source.
[0007] In some embodiments of this application, the second driving component includes a second rotary structure and a second link. One end of the second link is hinged to the eccentric position of the second rotary structure, and the other end of the second link is hinged to the limiting component. There are two second links. The second rotary structure drives the two limiting components to move closer or further apart from each other vertically through the two second links.
[0008] In some embodiments of this application, the first driving component includes a first rotary structure and a first connecting rod. One end of the first connecting rod is hinged to an eccentric position of the first rotary structure, and the other end of the first connecting rod is hinged to the limiting conveying component. The first rotary structure drives the limiting conveying component to reciprocate longitudinally through the first connecting rod.
[0009] In some embodiments of this application, the longitudinal spacing between two adjacent pressure arms in the limiting assembly can be adjusted.
[0010] The bag spring machine provided in this application includes a bag spring conveying mechanism, a spring feeding assembly, and a welding assembly. Longitudinally, the spring feeding assembly is located upstream of the bag spring conveying mechanism and is used to feed the spring into the bag in a compressed state. Longitudinally, the welding assembly is located downstream of the bag spring conveying mechanism and is used to form a transverse weld on the bag. The limiting conveying assembly longitudinally causes the spring to leave the spring feeding assembly and enter the bag, and under the conveying of the limiting conveying assembly, the spring reaches the welding position of the welding assembly.
[0011] In some embodiments of this application, the two limiting components of the limiting conveying assembly are located on the upper and lower sides of the end of the spring feeding assembly, and can move longitudinally so that the spring disengages from the spring feeding assembly and reaches the welding position of the welding assembly. The spring is within the limiting area during the process of disengaging from the spring feeding assembly, springing out of the bag, reaching the welding position of the welding assembly, and until the spring is packaged.
[0012] In some embodiments of this application, the welding assembly includes a welding knife and a welding head, the welding knife and the welding head being close to and separated from each other and encapsulating a spring.
[0013] In some embodiments of this application, the welding assembly can move forward longitudinally when clamping the cloth bag, thereby causing the cloth bag to move forward longitudinally.
[0014] The embodiments of this application have at least the following beneficial effects: In the bag spring conveying mechanism of the bag spring machine, when conveying cloth bags, the two limiting components can approach each other, and the springs in the cloth bags are confined between the four pressure arms, thereby preventing spring deformation or positional displacement. When the first drive component drives the limiting conveying component to move forward longitudinally, the mutually approaching limiting components enable the springs in the cloth bags to move forward and prevent spring deformation or positional displacement. This application can be widely applied in the field of bag spring technology.
[0015] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0028] This application relates to a bag spring machine, which includes a bag spring conveying mechanism and a welding assembly 3000. The bag spring conveying mechanism is used to convey a cloth bag with springs, and the springs and cloth bags are conveyed longitudinally. The welding assembly 3000 is used to form a weld on the cloth bag to seal the cloth bag with springs, thereby obtaining a bag spring string.
[0029] The longitudinal direction is parallel to the direction of spring conveying, and the X direction in the figure is the longitudinal direction. The transverse direction is parallel to the width of the bag, and the Y direction in the figure is the transverse direction. The weld formed by the welding assembly 3000 on the bag is formed in the transverse direction, and this weld is a transverse weld.
[0030] In the longitudinal direction, the welding assembly 3000 is located downstream of the limiting conveying assembly 1000 in the bag spring conveying mechanism. It is understood that the bag spring conveying mechanism conveys the spring-loaded bag downstream, and the welding assembly 3000 then welds the bag to obtain a weld.
[0031] Understandably, the welding assembly 3000 includes a welding head and a welding blade, which can be brought close to or moved away from each other. Specifically, the welding head and welding blade are brought close to each other and separated, encapsulating a spring.
[0032] Furthermore, the bag-packing spring machine includes a spring-feeding assembly for feeding springs into the bag in a compressed state. Specifically, the spring-feeding assembly is located upstream of the bag-packing spring conveying mechanism along the longitudinal direction.
[0033] It should be noted that the limiting conveying component 1000 in the bag spring conveying mechanism causes the spring to leave the spring feeding component and enter the bag along the longitudinal direction, and under the conveying of the limiting conveying component 1000, the spring reaches the welding position of the welding component 3000.
[0034] The other components and operation of the bag spring machine are already described in the relevant art to those skilled in the art, and will not be described in detail here. The structure of the bag spring conveying mechanism will be introduced below.
[0035] This application relates to a bag spring conveying mechanism, which includes a limiting conveying assembly 1000. After a compressed spring is loaded into a cloth bag, the limiting conveying assembly 1000 can confine the spring within the bag and convey it longitudinally forward. Under the action of the limiting conveying assembly 1000, the spring is confined within the bag, thereby preventing positional displacement of the spring within the bag. Furthermore, the limiting conveying assembly 1000 also prevents deformation of the spring within the bag.
[0036] Furthermore, the limiting conveying assembly 1000 includes two limiting assemblies 1100, which are arranged vertically at intervals and can move closer or further apart from each other in the vertical direction. The bag passes between the two limiting assemblies 1100, with one limiting assembly 1100 located on the upper side of the bag and the other on the lower side. When the two limiting assemblies 1100 are close together, they can restrict the spring in the bag, preventing the spring from shifting or deforming.
[0037] Specifically, the two limiting components 1100 of the limiting conveying assembly 1000 are located on the upper and lower sides of the end of the spring feeding assembly, respectively. When the two limiting components 1100 of the limiting conveying assembly 1000 approach each other vertically and move longitudinally, the spring disengages from the spring feeding assembly and reaches the welding position of the welding assembly 3000. The spring is in the limiting area during the process of disengaging from the spring feeding assembly, springing out in the bag, reaching the welding position of the welding assembly 3000, and until the spring is packaged.
[0038] The limiting assembly 1100 includes at least two pressure arms 1101, each pressure arm 1101 having a cantilevered end, the pressure arms 1101 extending laterally, and the pressure arms 1101 being arranged at longitudinal intervals. It should be noted that the pressure arms 1101 in the two limiting assemblies 1100 are paired.
[0039] Understandably, when the two limiting components 1100 approach each other, the two adjacent pressure arms 1101 in the limiting component 1100 and the corresponding two pressure arms 1101 in the other limiting component 1100 constitute a limiting area for restricting the spring in the bag. Specifically, of the four pressure arms 1101, one pair of pressure arms 1101 is located upstream of the spring, and the other pair of pressure arms 1101 is located downstream of the spring.
[0040] It should be noted that when the two limiting components 1100 approach each other, the distance between the two vertically spaced pressure arms 1101 is less than the diameter of the spring in the bag, so that the four pressure arms 1101 can limit the spring and thus jointly confine the spring inside the bag.
[0041] Furthermore, the limiting components 1100 are capable of synchronous reciprocating movement along the longitudinal direction, and the forward movement of the limiting components 1100 along the longitudinal direction causes the spring to move along the longitudinal direction. Specifically, when the two limiting components 1100 move forward along the longitudinal direction, the two pressure arms 1101 located upstream of the spring push the spring forward, causing the spring to move forward within the bag. It is understood that when the two limiting components 1100 approach each other, at least the two pressure arms 1101 located upstream of the spring can abut against the spring.
[0042] In some examples, when the two limiting components 1100 approach each other, the two pressure arms 1101 located upstream of the spring abut against the spring. In other examples, when the two limiting components 1100 approach each other, both the two pressure arms 1101 located upstream of the spring and the two pressure arms 1101 located downstream of the spring abut against the spring.
[0043] Understandably, in order for the pressure arm 1101 to push the spring to move within the bag, the pressure arm 1101 and the bag surface are in a loose contact, and the pressure arm 1101 and the bag are in a relaxed clamping state. In this case, when the two limiting components 1100 approach each other, the pressure arm 1101 does not clamp the bag, so that the pressure arm 1101 can move smoothly on the surface of the bag.
[0044] It should be noted that when the limiting assembly 1100 includes at least three pressure arms 1101, the limiting assembly 1100 can simultaneously limit and transport multiple springs in the bag.
[0045] In some embodiments, the longitudinal spacing between two adjacent pressure arms 1101 in the limiting assembly 1100 can be adjusted to accommodate springs with different waist diameters.
[0046] Specifically, the limiting component 1100 includes a first mounting base 1102, a pressure arm 1101 disposed on the first mounting base 1102, and the pressure arm 1101 can be moved longitudinally on the first mounting base 1102 to adjust its position.
[0047] In some examples, the first mounting base 1102 is provided with a mounting groove that extends longitudinally, and one end of the pressure arm 1101 is arranged in the mounting groove via a slider.
[0048] It should be noted that, regarding the connection between the pressure arm 1101 and the first mounting base 1102, there are at least the following alternative embodiments.
[0049] In some alternative embodiments, the first mounting base 1102 is provided with a longitudinally extending guide rail.
[0050] In some alternative embodiments, the first mounting base 1102 is provided with a guide rod extending longitudinally.
[0051] In some embodiments, the limiting conveying component 1000 includes a first driving component 2100, which is disposed upstream or downstream of the limiting component 1100. Under the drive of the first driving component 2100, the limiting component 1100 can move synchronously back and forth along the longitudinal direction.
[0052] The first drive assembly 2100 includes a first rotary structure 2101 and a first connecting rod 2102. One end of the first connecting rod 2102 is hinged to an eccentric position of the first rotary structure 2101, and the other end of the first connecting rod 2102 is hinged to the limiting and conveying assembly 1000. It can be understood that the first rotary structure 2101, the first connecting rod 2102, and the limiting and conveying assembly 1000 constitute a crank-slider mechanism.
[0053] It is understood that the first drive component 2100 includes a first driver 2103, the first driver 2103 includes a motor, the first driver 2103 drives the first rotary structure 2101 to rotate, and the first rotary structure 2101 drives the limiting conveying component 1000 to move longitudinally reciprocally through the first connecting rod 2102.
[0054] Furthermore, the limiting conveying assembly 1000 includes a second mounting base 1201, and the limiting assembly 1100 is disposed on the second mounting base 1201. The second mounting base 1201 is hinged to the first connecting rod 2102. The first driving assembly 2100 drives the second mounting base 1201 to reciprocate longitudinally to realize the reciprocating movement of the limiting conveying assembly 1000.
[0055] In some examples, the limiting conveying assembly 1000 includes a first guide structure 1202, and a second mounting base 1201 is movably disposed on the first guide structure 1202. Guided by the first guide structure 1202, a first drive assembly 2100 drives the limiting conveying assembly 1000 to reciprocate longitudinally.
[0056] Specifically, the first guide structure 1202 includes a guide rail extending longitudinally, and the second mounting base 1201 is movably disposed on the guide rail by means of a slider.
[0057] Regarding the first guide structure 1202, at least the following alternative embodiments also exist.
[0058] In some alternative embodiments, the first guide structure 1202 includes a guide groove extending longitudinally.
[0059] In some alternative embodiments, the first guide structure 1202 includes a guide rod extending longitudinally.
[0060] In some examples, the first rotary structure 2101 is configured as a wheel, which is connected to the shaft of the first driver 2103. The hinge position of the first link 2102 and the first rotary structure 2101 is located on the side of the wheel and off the center of rotation of the wheel.
[0061] Regarding the first rotating structure 2101, at least the following alternative embodiments also exist.
[0062] In some alternative embodiments, the first rotating structure 2101 is configured as a sector wheel.
[0063] In some alternative embodiments, the first rotary structure 2101 is configured as a swing arm, one end of which is disposed on the shaft of the first driver 2103, and the other end of which is hinged to the first connecting rod 2102.
[0064] Regarding the structure of the first drive assembly 2100, at least the following alternative configurations exist: the first drive assembly 2100 includes a hydraulic cylinder, a linear motor, a rack and pinion mechanism, a belt drive mechanism, or a lead screw mechanism.
[0065] In some embodiments, the limiting conveying assembly 1000 includes at least one second driving assembly 2200, and both limiting assemblies 1100 are connected to the second driving assembly 2200. It is understood that, driven by the second driving assembly 2200, the two limiting assemblies 1100 move closer to or further away from each other.
[0066] Specifically, the limit conveying assembly 1000 configures a shared second drive assembly 2200 for the two limit assemblies 1100, so that the two limit assemblies 1100 move closer or further apart synchronously. Alternatively, the limit conveying assembly 1000 configures a second drive assembly 2200 for each of the two limit assemblies 1100.
[0067] In some embodiments, the second drive assembly 2200 includes a second rotary structure 2201 and a second connecting rod 2202. One end of the second connecting rod 2202 is hinged to an eccentric position of the second rotary structure 2201, and the other end of the second connecting rod 2202 is hinged to the limiting assembly 1100. Specifically, the second connecting rod 2202 is hinged to the first mounting base 1102. It can be understood that the second rotary structure 2201, the second connecting rod 2202, and the limiting assembly 1100 constitute a crank-slider mechanism.
[0068] It is understood that the second drive assembly 2200 includes a second driver, which is disposed on the second mounting base 1201. Further, the second driver includes a motor, which drives the second rotary structure 2201 to rotate, thereby causing the second rotary structure 2201 to move the limit assembly 1100 via a connecting rod.
[0069] It should be noted that in some examples, the two limiting components 1100 share a single second driving component 2200. In this case, the second driving component 2200 has two second connecting rods 2202, and the hinge positions of the two second connecting rods 2202 on the second rotary structure 2201 are symmetrically distributed about the rotation center of the second rotary structure 2201, so that the second rotary structure 2201 can drive the two limiting components 1100 to move closer or further apart through the two second connecting rods 2202. In other examples, each of the two limiting components 1100 is equipped with a second driving component 2200, and the second driving component 2200 has only one second connecting rod 2202.
[0070] In some examples, the second rotary structure 2201 is configured as a wheel, which is connected to the shaft of the second driver, and the hinge position of the second link 2202 and the second rotary structure 2201 is located on the side of the wheel and off the center of rotation of the wheel.
[0071] Regarding the second rotary structure 2201, at least the following alternative embodiments also exist.
[0072] In some alternative embodiments, the second rotating structure 2201 is configured as a sector wheel.
[0073] In other alternative embodiments, the second rotary structure 2201 is configured as a swing arm, and the second connecting rod 2202 is hinged to the end of the swing arm. When the two limiting components 1100 share a single second drive component 2200, the middle portion of the swing arm is located at the pivot of the second drive. When the two limiting components 1100 are each configured with a second drive component 2200, the other end of the swing arm is located at the pivot of the second drive.
[0074] Regarding the structure of the second drive assembly 2200, at least the following alternatives exist: the second drive assembly 2200 includes a hydraulic cylinder, a linear motor, a rack and pinion mechanism, a belt drive mechanism, or a lead screw mechanism.
[0075] In some examples, the limiting conveying assembly 1000 includes a second guide structure 1203, on which a first mounting base 1102 of the limiting assembly 1100 is movably disposed. Guided by the second guide structure 1203, the second drive assembly 2200 drives the two limiting assemblies 1100 to move closer to or further away from each other.
[0076] Specifically, the second guide structure 1203 includes a guide rail, and the first mounting base 1102 is movably mounted on the guide rail via a slider.
[0077] Regarding the second guide structure 1203, at least the following alternative embodiments also exist.
[0078] In some alternative embodiments, the second guide structure 1203 includes a guide groove.
[0079] In some alternative embodiments, the second guide structure 1203 includes a guide rod.
[0080] In some embodiments, at least two limiting conveying assemblies 1000 are provided, and the limiting conveying assemblies 1000 are distributed laterally at intervals on both sides of the bag.
[0081] Specifically, a limiting conveying assembly 1000 is provided on one side of the bag along its longitudinal direction, and a limiting conveying assembly 1000 is also provided on the other side of the bag along its longitudinal direction. It can be understood that the second mounting seats 1201 of the limiting conveying assemblies 1000 on both sides are distributed laterally at intervals, and the area between the second mounting seats 1201 is the conveying channel of the bag along its longitudinal direction. The second mounting seats 1201 are located on both sides of the bag.
[0082] It should be noted that the limiting components in the limiting conveying assemblies 1000 on both sides of the bag move closer to each other alternately, and the limiting conveying assemblies 1000 on both sides of the bag also move the springs longitudinally alternately. Specifically, on both sides of the bag, the limiting components 1100 of one side of the limiting conveying assemblies 1000 move closer to each other and then move longitudinally, while the limiting components 1100 of the other side of the limiting conveying assemblies 1000 move further apart and then move in the opposite direction longitudinally. The limiting conveying assemblies 1000 on both sides of the bag move in this cyclical manner, thereby realizing the forward conveying of the springs in the bag.
[0083] Understandably, on both sides of the bag, the limiting components 1100 of one side of the limiting conveying assembly 1000 move closer together and then move forward longitudinally, while the limiting components 1100 of the other side of the limiting conveying assembly 1000 move further apart and then move backward longitudinally. In this case, at the end of the spring feeding assembly, the limiting conveying components 1000 alternately hold the springs, thereby limiting the position of the springs in the bag and conveying the springs one by one into the bag and to the welding position.
[0084] The bag spring conveying mechanism allows the limiting conveying components 1000 on both sides of the bag to move alternately longitudinally, and the limiting components 1100 in the limiting conveying components 1000 on both sides of the bag to move closer or further apart vertically. This allows more time for the springs to fully unfold when they are delivered from the spring feeding assembly, and enables them to maintain a stable state in the bag for sealing and welding. This reduces the failure rate of the retaining springs and improves the operating efficiency of the equipment.
[0085] In some examples, the first drive components 2100 configured on both sides of the bag's limiting conveying components 1000 share a common power source. Specifically, a drive shaft is provided between the two first drive components 2100, extending laterally. The first rotating structures 2101 of the first drive components 2100 are all located on the drive shaft. The drive shaft is connected to the rotating shaft of the first driver 2103, and can rotate along its own length's central axis, thereby enabling the two first drive components 2100 to operate synchronously.
[0086] Based on the above introduction of the bag spring conveying mechanism, the following is a supplementary explanation of the structure of the bag spring machine.
[0087] When the limiting conveying component 1000 conveys the spring in the cloth bag to the position of the welding component 3000 along the longitudinal direction, the two limiting components 1100 move away from each other, while the welding head and welding knife of the welding component 3000 move closer to each other, thereby completing the welding of the transverse weld on the cloth bag.
[0088] Furthermore, the welding assembly 3000 is capable of reciprocating back and forth longitudinally. When the welding assembly 3000 clamps the cloth bag, it can move forward longitudinally and drive the cloth bag forward longitudinally. While the welding assembly 3000 moves forward, another limiting conveying assembly 1000 conveys the next spring in the cloth bag forward to the welding position.
[0089] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
