Description

Technical Field

[0001] This utility model relates to the field of spring cushion production machinery technology, specifically to a push spring device applied to double-row bagged spring cushion assembly. Background Technology

[0002] Spring cushions are typically made by assembling multiple rows of pocket springs.

[0003] There is a type of double-row pocket spring cushion. In its production, two rows of pocket spring strings are first combined together to form a double-row pocket spring string, and then multiple double-row pocket spring strings are combined together to form a double-row pocket spring cushion. At this time, a push spring device is needed to push the double-row pocket spring strings to the combination mechanism.

[0004] However, existing push-spring mechanisms are generally simple push plates or combinations of push plates with multiple fixed top plates to limit the springs. However, since double-row bagged spring strings require limiting and positioning of the bagged springs in both rows, if a simple push plate is used for normal conveying and pushing, the bagged springs in the double-row bagged spring strings will obviously shift, which is obviously detrimental to subsequent assembly processes and easily generates defective products. If a push plate with top plates is used, the push plate itself does not contact the double-row bagged spring strings during pushing, but the top plate already contacts the double-row bagged spring strings. In this case, it is obviously difficult to ensure that the double-row bagged spring strings are properly arranged under the limiting position of the top plate. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present invention aims to provide a push spring device for use in double-row bagged spring cushion assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A push spring device for use in double-row bagged spring cushion assembly, comprising a feeding mechanism, a push plate, a top plate, a first flap, and a second flap; The feeding mechanism is used to input the double-row bagged spring strings from the first direction to the designated position; A pusher plate is provided on one side of the feeding mechanism. The pusher plate is capable of pushing out the double-row bagged spring string from the feeding mechanism in the second direction. The pusher plate is provided with at least one through groove. A top plate is provided in the through slot corresponding to the pusher plate. The pusher plate and the top plate can move synchronously / independently along the second direction. All the top plates can extend and retract independently / synchronously along the second direction in the through slot. The top plate is used to limit the position of the double-row bag spring string. The first flap and the second flap are located on the other side of the feeding mechanism. The first flap and the second flap are spaced apart along a third direction. The first flap and the second flap can be moved or swung independently. When the second flap moves or swings to be perpendicular to the conveying surface of the feeding mechanism, and the pusher plate pushes the double-row bag springs to the designated position, at least the second flap and the pusher plate form a limiting space. The second flap and the pusher plate cooperate to limit the double-row bag spring string in the second direction. The top plate extends and retracts within the limiting space through the through groove to limit the bag springs of the double-row bag spring string.

[0007] Furthermore, the second flap includes a waiting area and a flipping area. When the flipping area is flipped to be perpendicular to the conveying surface of the feeding mechanism, and the pusher plate pushes the double-row bag spring string to the waiting area, the pusher plate, the waiting area and the flipping area constitute a limiting space. When both the first and second flaps are displaced or swung to be parallel to the conveying surface of the feeding mechanism, the first and second flaps and / or the feeding mechanism cooperate to clamp the double-row bag springs in a third direction.

[0008] Furthermore, when the second flap flips to be perpendicular to the conveying surface of the feeding mechanism, and the pusher plate pushes the double-row bag spring string to the designated position of the feeding mechanism, the pusher plate, the feeding mechanism and the second flap constitute a limiting space.

[0009] Furthermore, a first baffle is provided at one end of the pusher plate, which is used to limit the conveying position of the feeding mechanism.

[0010] Furthermore, a second baffle is provided at the other end of the pusher plate. The second baffle can swing or shift to avoid the double-row bagged springs conveyed by the feeding mechanism. The second baffle is used to limit the end of the input double-row bagged springs. The position of the second baffle is adjustable.

[0011] Furthermore, when the top plate extends from the through groove along the pushing direction of the pusher plate, two adjacent top plates or the top plate and the first baffle or the top plate and the second baffle form a limiting groove. Each limiting groove that can limit the double-row bag spring string limits at least one row of bag springs in the double-row bag spring string.

[0012] Furthermore, when both the first and second flaps are flipped to be parallel to the conveying surface of the feeding mechanism, the first and second flaps can clamp and limit the double-row bagged spring strings.

[0013] Furthermore, the feeding mechanism is a feeding conveyor belt.

[0014] This utility model has the following beneficial effects: This utility model discloses a push-spring device for a double-row bagged spring cushion assembly. By setting a flip-up second flap, at least the second flap and the push plate form a limiting space, thereby ensuring that the double-row bagged spring string will not deviate when the top plate limits the double-row bagged spring string. Secondly, by setting a retractable top plate, the spring spacing of the double-row bagged spring string is limited in the limiting space, effectively ensuring the accuracy of the spring spacing of the double-row bagged spring string, which is beneficial to the subsequent assembly process.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0017] like Figures 1-11 The present invention discloses a push spring device for a double-row bagged spring cushion assembly, comprising a feeding mechanism 1, a push plate 2, a top plate 3, a first flap 4, and a second flap 5. Feeding mechanism 1 is used to input double-row bagged spring strings from the first direction to the designated position; Pusher plate 2 is located on one side of feeding mechanism 1. Pusher plate 2 can push double-row bag springs out of feeding mechanism 1 in the second direction. Pusher plate 2 is provided with at least one through groove 21. A top plate 3 is provided in the through groove 21 corresponding to the pusher plate 2. The pusher plate 2 and the top plate 3 can move synchronously / independently along the second direction. All the top plates 3 can extend and retract independently / synchronously along the second direction in the through groove 21. The top plate 3 is used to limit the spring spacing of the double-row bag spring string. The first flap 4 and the second flap 5 are located on the other side of the feeding mechanism 1. The first flap 4 and the second flap 5 are spaced apart along the third direction. The first flap 4 and the second flap 5 can be moved or swung independently. When the second flap 5 is displaced or swings to be perpendicular to the conveying surface of the feeding mechanism 1, and the pusher plate 3 pushes the double-row bag springs to the designated position, at least the second flap 5 and the pusher plate 2 form a limiting space. The second flap 5 and the pusher plate 2 cooperate to limit the double-row bag springs in the second direction. The top plate 3 extends and retracts within the limiting space through the through groove 21 to limit the double-row bag springs. When the first flap 4 and the second flap 5 are both displaced or swung to be parallel to the conveying surface of the feeding mechanism 1, the first flap 4 and the second flap 5 and / or the feeding mechanism 1 cooperate to clamp the double-row bag springs in a third direction.

[0018] It should be noted that, as Figure 1 As shown, the first direction is the left-right direction, the second direction is the front-back direction, and the third direction is the up-down direction.

[0019] To further illustrate the specific uses of this utility model, such as Figures 6-11 The diagram shown is a schematic diagram of the present invention in specific use.

[0020] In practical use, the feeding mechanism 1 conveys the double-row bagged spring string to a designated position (e.g., Figure 6 (As shown), then the second flap 5 is displaced or swung to be perpendicular to the conveying surface of the feeding mechanism 1, and then the pusher plate 2 pushes the double-row bagged spring string to the designated position. At this time, the double-row bagged spring string is located within the limiting space formed by the cooperation of the second flap 5 and the pusher plate 2. At this time, the second flap 5 and the pusher plate 2 limit the double-row bagged spring string in the second direction (as shown). Figure 7 As shown), the top plate 3 then extends from the through slot 21 into the limiting space, at which point two adjacent top plates 3 limit at least one row of pocket springs (as shown). Figure 8 As described above), multiple sets of top plates 3 cooperate to limit the position of multiple rows of bagged springs in the first direction of the double-row bagged spring string. At this time, the double-row bagged spring string is limited in both the first and second directions and its position is accurate, thus completing the positioning process. Then, the first flip plate 4 is displaced or flipped to be parallel to the conveying surface of the feeding mechanism 1. At this time, the first flip plate 4 can cooperate with the second flip plate 5 or the feeding mechanism 1 to clamp the double-row bagged spring string. (During this process, the second flip plate 5 can be flipped or displaced synchronously or kept in a vertical state to limit the springs and wait for the first flip plate 4 to complete the clamping before displaced or flipped to be parallel to the conveying surface of the feeding mechanism. It is only necessary to ensure that when the pusher plate 2 pushes the double-row bagged spring string outward, both the first flip plate 4 and the second flip plate 5 are in a state parallel to the conveying surface of the feeding mechanism 1.) At this time, the position of the double-row bagged spring string in the clamping state can remain unchanged (e.g., Figure 9 (as shown), then if the second flap does not flip or shift to be parallel to the conveyor surface, the second flap flips or shifts to be parallel to the conveyor surface (as shown). Figure 10 As shown), finally, the pusher plate 2 pushes out the double-row bag spring string (during the pushing process, the top plate 3 can retract from the through slot 21, or it can retract after being pushed to a specific position; it only needs to retract and reset before the next double-row bag spring string is input). Figure 11 As shown), the material pushing process is completed in this way, and the pushing plate 2 and the top plate 3 are reset along the second direction to wait for the input of the next double-row bag spring string.

[0021] It should be noted that the displacement or flipping of the first and second flaps is driven by external power sources, such as motors or cylinders.

[0022] It should be noted that the pushing action of the pusher plate and the extension and retraction action of the top plate are both driven by an external power source, generally an external power source such as a motor or cylinder.

[0023] The advantages of this utility model are: 1. By setting a flip-up second flap, at least the second flap and the push plate form a limiting space, thereby ensuring that the double-row bag spring string will not deviate when the top plate limits the double-row bag spring string; 2. By setting a retractable top plate, the spring spacing of the double-row bag spring string is limited in the limiting space, effectively ensuring the accuracy of the spring spacing of the double-row bag spring string, which is beneficial to the subsequent assembly process.

[0024] In one embodiment of this utility model, the second flip plate 5 includes a waiting area 51 and a flipping area 52. When the flipping area 52 is flipped to be perpendicular to the conveying surface of the feeding mechanism 1, and the pusher plate 3 pushes the double-row bag spring string to the waiting area 51, the pusher plate 2, the waiting area 51 and the flipping area 52 constitute a limiting space.

[0025] More preferably, by setting up a waiting area 51, the double-row bagged spring string can be pushed away from the feeding mechanism 1 before being positioned, which can avoid the double-row bagged spring string being affected by the feeding mechanism during the positioning process. At this time, the first flip plate 4 only needs to cooperate with the second flip plate 5 to clamp the bagged spring string.

[0026] In one embodiment of this utility model, when the second flap 5 is flipped to be perpendicular to the conveying surface of the feeding mechanism 1, and the pusher plate 2 pushes the double-row bag spring string to the designated position of the feeding mechanism 1, the pusher plate 3, the feeding mechanism 1 and the second flap 5 constitute a limiting space.

[0027] More preferably, at this time, the first flap 4 needs to partially cooperate with the feeding mechanism 1 to clamp the double-row bagged spring string.

[0028] Furthermore, a first baffle 22 is provided at one end of the pusher plate 2, which is used to limit the conveying position of the feeding mechanism 1.

[0029] More preferably, by setting the first baffle 22, the position of the first row of bag springs in the double-row bag spring string is limited, which is beneficial to the subsequent positioning and assembly process.

[0030] Furthermore, a second baffle 23 is provided at the other end of the pusher plate. The second baffle 23 can swing or move to avoid the double-row bagged springs conveyed by the feeding mechanism. The second baffle 23 is used to limit the end of the input double-row bagged springs. The position of the second baffle 23 is adjustable.

[0031] More preferably, by setting a second baffle 23, the position of the last row of bag springs in the double-row bag spring string is limited, and subsequent positioning and assembly processes are utilized.

[0032] Furthermore, when the top plate 3 extends out from the through groove 21 along the pushing direction of the pusher plate 2, two adjacent top plates 3 or the top plate 3 and the first baffle 22 or the top plate 3 and the second baffle 23 form a limiting groove. Each limiting groove that can limit the double-row bag spring string limits at least one row of bag springs in the double-row bag spring string.

[0033] It should be noted that, in the embodiments of this utility model, the bag springs arranged in a first direction in a double-row bag spring series are defined as a row, and the bag springs arranged in a second direction are defined as a column.

[0034] More specifically, in one embodiment, the distance between two adjacent top plates 3 or between top plate 3 and the first baffle 22 or between top plate 3 and the second baffle 23 is the center distance between two adjacent bag springs along the first direction, in which case each limiting groove can limit one row of bag springs in the double-row bag spring string.

[0035] Preferably, this embodiment can limit the position of each row of bag springs, which can effectively ensure the accurate positioning of each bag spring.

[0036] More specifically, in one embodiment, the distance between two adjacent top plates 3 or between top plate 3 and the first baffle 22 or between top plate 3 and the second baffle 23 is the center distance between three adjacent bag springs along the first direction, in which case each limiting groove can limit the two rows of bag springs in the double-row bag spring string.

[0037] Preferably, this embodiment can limit the position of two adjacent rows of bag springs, and can be adapted to the positioning production of double-row bag spring strings in the shape of a four-leaf clover. The bag spring string with the four-leaf clover structure is best positioned by limiting the position of two rows of bag springs.

[0038] When the second flap 5 is displaced or swings to be perpendicular to the conveying surface of the feeding mechanism 1, and the pusher plate 2 pushes the double-row bag springs to the designated position, at least the second flap 5 and the pusher plate 2 form a limiting space. When the top plate 3 extends and retracts within the limiting space through the through groove 21 to limit the double-row bag springs, the first flap 4 is in a state of flipping to the designated position to avoid the double-row bag springs.

[0039] Preferably, when the first flap 4 is in the avoidance state, it can effectively prevent the first flap 4 from cooperating with the second flap 5 and / or the feeding mechanism 1 to clamp the bag spring string, which would cause the bag spring string to fail to be positioned accurately.

[0040] Furthermore, when both the first flap 4 and the second flap 5 are flipped to be parallel to the conveying surface of the feeding mechanism 1, the first flap 4 and the second flap 5 can clamp and limit the double-row bagged spring strings.

[0041] More preferably, when the first flap 4 and the second flap 5 clamp the double-row bagged spring string, the double-row bagged spring string is in a compressed state, which can ensure that the double-row bagged spring string maintains an accurate position during subsequent pushing, which is beneficial to the subsequent assembly process.

[0042] Furthermore, the feeding mechanism 1 is a feeding conveyor belt.

[0043] More preferably, the conveyor belt has the advantages of stable, accurate and fast conveying, which is beneficial for the input of double-row bagged spring strings.

[0044] More preferably, the center distance between two adjacent top plates 3 is at least equal to the center distance between two adjacent through slots 21, and the spacing between two adjacent top plates 3 is adjustable.

[0045] In one specific embodiment of the adjustable top plate 3 of this utility model, the pusher plate is provided with a plurality of through slots 21, which can make the center distance between two adjacent top plates 3 equal to the center distance between two adjacent through slots 21, or make the center distance between two top plates 3 equal to the center distance between three or more adjacent through slots 21. In this case, the spacing between two adjacent top plates 3 can be adjusted by adjusting the number of through slots 21 between two adjacent top plates 3.

[0046] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
