A spring compression conveying device

Abstract

The present invention discloses a spring compression conveying device, which includes a chassis and a conveying mechanism. Two conveying mechanisms are arranged oppositely. The conveying mechanism is composed of a flat conveying section and an arc section, both of which are not provided with baffles. A number of upright columns are arranged in both the flat conveying section and the arc section. By setting the upright columns in the present invention and replacing the original baffles, the contact between the conveyor belt / conveyor chain and the upright columns is a point contact, reducing the frictional resistance generated during the movement of the conveyor belt / conveyor chain and avoiding damage to the conveyor belt / conveyor chain due to excessive friction. Secondly, by setting the upright columns and replacing the original pulley / sprocket, the structure is simplified without corresponding mating relationships, avoiding the situation of the conveyor belt / conveyor chain being stuck. Finally, by arranging the upright columns along the arc, the compression distance is significantly reduced compared to the inclined straight edge, reducing the length of the compression section. At the same time, it can effectively improve the tensioning effect of the upright columns on the conveyor belt / conveyor chain, reduce the possibility of the conveyor belt / conveyor chain falling off from the upright columns, and improve the stability.

Description

Technical Field

[0001] The present invention relates to the technical field of bagged spring production equipment, and particularly relates to a spring compression and conveying device. Background Art

[0002] A spring mattress is a common piece of furniture, which is formed by bonding several bagged spring strips.

[0003] When producing bagged spring strips, the springs need to be compressed and then put into bags for welding. At this time, a compression and conveying device is required.

[0004] The existing compression and conveying device generally consists of one or two annular conveying devices that are connected end to end and arranged oppositely. The annular conveying device at the input end is inclined, and a baffle for supporting the conveying is provided at the input end. The two oppositely arranged annular conveying devices form a certain angle. The annular conveying device at the output end is arranged in parallel. During the conveying process, the springs are gradually compressed by the inclined annular conveying device at the input end and finally horizontally output from the annular conveying device at the output end, thus realizing compression and conveying.

[0005] However, the existing compression and conveying device has obvious disadvantages: 1. The length of the inclined compression structure is relatively long, which is not conducive to rapid production; 2. During the compression and conveying process, the springs will tightly press the conveyor belt / conveyor chain of the conveying device against the baffle, which will greatly increase the friction between the conveyor belt / conveyor chain and the baffle, and it is easy to damage the conveyor belt / conveyor chain after long-term use.

[0006] In view of these problems, there is an existing compression and conveying device whose compression section is composed of several belt wheels / sprockets, thus avoiding the use of a baffle. However, this structure requires the installation of multiple belt wheels / sprockets and ensures that the belt wheels / sprockets are tightly connected to the conveyor belt / conveyor chain. Therefore, the structure is complex. At the same time, the compression force of the springs is likely to cause the belt wheels / sprockets to be tightly pressed against the conveyor belt / conveyor chain, resulting in the situation where the belt wheels / sprockets cannot rotate, which is very dangerous. Summary of the Invention

[0007] Aiming at the deficiencies of the prior art, the present invention aims to provide a spring compression and conveying device.

[0008] To achieve the above object, the present invention adopts the following technical solutions:

[0009] A spring compression conveying device, comprising a chassis and a conveying mechanism. Two said conveying mechanisms are arranged oppositely. The conveying mechanism is formed by winding a section of conveyor belt / conveyor chain. The conveyor belt / conveyor chain forms a horizontal conveying section and an arc section. The arc section is in the shape of a convex arc. The output end of the arc section is tangent to the input end of the horizontal conveying section. There are no baffles in both the horizontal conveying section and the arc section. A number of upright columns are arranged in both the horizontal conveying section and the arc section. By arranging the upright columns along the arc, the compression distance is significantly reduced compared to the inclined straight edge. The conveyor belt / conveyor chain in both the horizontal conveying section and the arc section is wound around the upright columns, and the contact between the conveyor belt / conveyor chain and the upright columns is a point contact. The convex arcs of the arc sections of the two said conveying mechanisms are arranged oppositely;

[0010] The conveying mechanism further comprises a first connecting wheel, a second connecting wheel, a third connecting wheel, a first mounting bracket and a second mounting bracket. The first connecting wheel, the second connecting wheel and the third connecting wheel are all mounted on the chassis. The conveyor belt / conveyor chain is wound around the first connecting wheel, the second connecting wheel and the third connecting wheel. The first connecting wheel and the second connecting wheel form the horizontal conveying section, and the arc section is formed between the second connecting wheel and the third connecting wheel. A first mounting bracket is arranged between the first connecting wheel and the second connecting wheel, and a second mounting bracket is arranged between the second connecting wheel and the third connecting wheel. There are no baffles between the first connecting wheel, the second connecting wheel and the third connecting wheel. A number of upright columns are fixedly mounted on both the first mounting bracket and the second mounting bracket. One of the opposite sides of the two said second mounting brackets is an arc surface. The upright columns are arranged along the arc surface of the second mounting bracket. The conveyor belt / conveyor chain at the arc section is in close contact with the upright columns mounted on the second mounting bracket;

[0011] The conveying mechanism is provided with one or more conveyor belts / conveyor chains arranged parallel to each other vertically.

[0012] Further, a notch is provided at the top of the second mounting bracket, and a mounting hole is provided at the bottom of the second mounting bracket. A convex block is provided at the bottom of the upright column. The upright column passes through the notch, and the convex block is in interference fit with the mounting hole so that the upright column is mounted on the second mounting bracket.

[0013] Further, a first through groove is provided on the first mounting bracket. The upright column is fixedly arranged in the first through groove, and the arc surface of the upright column extends outwards from the through groove.

[0014] Further, a second through groove parallel to the arc surface is provided at the arc surface of the second mounting bracket. The upright column is mounted in the second through groove, and the arc surface of the upright column extends outwards from the second through groove.

[0015] Further, a tension pulley and an elastic member are also provided on the chassis. The tension pulley is slidably connected to the chassis. One end of the elastic member abuts against the tension pulley, and the other end of the elastic member abuts against the chassis. The conveyor belt / conveyor chain is wound around the first connecting pulley, the second connecting pulley, the third connecting pulley and the tension pulley.

[0016] The present invention has the following beneficial effects:

[0017] A spring compression conveying device of the present invention is provided with a column, replacing the original baffle. The conveyor belt / conveyor chain is in point contact with the column, reducing the frictional resistance generated during the movement of the conveyor belt / conveyor chain and avoiding damage to the conveyor belt / conveyor chain due to excessive friction. Secondly, by providing a column and replacing the original pulley / sprocket, the structure is simplified. At the same time, there is no corresponding matching relationship between the conveyor belt / conveyor chain and the column, and the situation of the conveyor belt / conveyor chain being stuck will not occur. Finally, the column is arranged along the arc, significantly reducing the compression distance compared to the inclined straight edge compression, thereby reducing the length of the compression section and improving the compression efficiency. At the same time, the column arranged along the arc can effectively improve the tensioning effect of the column on the conveyor belt / conveyor chain, reduce the possibility of the conveyor belt / conveyor chain falling off from the column, and improve the stability.

[0025] Aiming at the deficiencies of the prior art, the present invention aims to provide a spring compression conveying device.

[0026] To achieve the above object, the present invention adopts the following technical solutions:

[0027] A spring compression conveying device comprises a chassis 1 and a conveying mechanism 2. The two conveying mechanisms 2 are arranged oppositely. The conveying mechanism 2 is formed by winding a section of conveyor belt / conveyor chain 6. The conveyor belt / conveyor chain 6 forms a horizontal conveying section and an arc section. The arc section is in the shape of a convex arc. The output end of the arc section is tangent to the input end of the horizontal conveying section. There are no baffles in both the horizontal conveying section and the arc section. A number of upright columns 9 are arranged in both the horizontal conveying section and the arc section. The conveyor belt / conveyor chain 6 in the horizontal conveying section and the arc section is wound around the upright columns 9. The convex arcs of the arc sections of the two conveying mechanisms 2 are arranged oppositely.

[0028] When the present invention is in use, the spring is input through the input end of the compression section. At this time, both ends of the spring are in close contact with the conveyor belt / conveyor chain 6. During the conveying process of the compression section, the spring is compressed as the compression section is conveyed. During the compression process, in the gap between the two upright columns 9, the two ends of the spring generate a compression force on the conveyor belt / conveyor chain 6, causing the conveyor belt / conveyor chain 6 to deform. At the same time, part of the spring rebounds to avoid plastic deformation. A number of the upright columns 9 located on the second mounting bracket 8 form an arc-shaped compression section, thereby reducing the length of the compression section.

[0029] The advantages of the present invention are as follows: 1. By arranging the upright columns 9 and replacing the original baffles, the contact between the conveyor belt / conveyor chain 6 and the upright columns 9 is point contact, reducing the frictional resistance generated during the movement of the conveyor belt / conveyor chain 6 and avoiding damage to the conveyor belt / conveyor chain 6 due to excessive friction; 2. By arranging the upright columns 9 and replacing the original belt pulleys / sprocket wheels, the structure is simplified. At the same time, there is no corresponding matching relationship between the conveyor belt / conveyor chain 6 and the upright columns 9, and the situation of the conveyor belt / conveyor chain 6 being stuck will not occur; 3. By arranging the upright columns 9 along the arc, the compression distance is significantly reduced compared with the inclined straight edge compression, thereby reducing the length of the compression section and improving the compression efficiency. At the same time, arranging the upright columns 9 along the arc can effectively improve the tensioning effect of the upright columns 9 on the conveyor belt / conveyor chain 6, reduce the possibility of the conveyor belt / conveyor chain falling off from the upright columns 9, and improve the stability.

[0030] Further, the conveying mechanism 2 further includes a first connecting wheel 3, a second connecting wheel 4, a third connecting wheel 5, a first mounting bracket 7 and a second mounting bracket 8. The first connecting wheel 3, the second connecting wheel 4 and the third connecting wheel 5 are all mounted on the chassis 1. The conveyor belt / conveyor chain 6 is wound around the first connecting wheel 3, the second connecting wheel 4 and the third connecting wheel 5. The first connecting wheel 3 and the second connecting wheel 4 form a flat conveying section, and an arc section is formed between the second connecting wheel 4 and the third connecting wheel 5. A first mounting bracket 7 is provided between the first connecting wheel 3 and the second connecting wheel 4, and a second mounting bracket 8 is provided between the second connecting wheel 4 and the third connecting wheel 5. No baffle is provided between the first connecting wheel 3, the second connecting wheel 4 and the third connecting wheel 5. A plurality of upright columns 9 are fixedly mounted on both the first mounting bracket 7 and the second mounting bracket 8. One of the two opposite sides of the second mounting bracket 8 is an arc surface, and the upright columns 9 are arranged along the arc surface of the second mounting bracket 8. The conveyor belt / conveyor chain 6 at the arc section is in close contact with the upright columns 9 mounted on the second mounting bracket 8.

[0031] More specifically, by providing the first connecting wheel 3, the second connecting wheel 4 and the third connecting wheel 5, the conveyor belt / conveyor chain 6 can be wound around the first connecting wheel 3, the second connecting wheel 4 and the third connecting wheel 5 to form two sections of structure.

[0032] More specifically, by providing an arc surface on the second mounting bracket 8 and arranging the upright columns 9 along the arc surface, when the conveyor belt / conveyor chain 6 is in close contact with the upright columns 9, a conveying section in the shape of an arc will be formed, which is the arc section.

[0033] Further, the first mounting bracket 7 is provided with a first through groove 71, and the upright column 9 is fixedly arranged in the first through groove 71. The arc surface of the upright column 9 extends outwards from the first through groove 71.

[0034] It should be noted that the first through groove 71 is provided to prevent the conveyor belt / conveyor chain from directly contacting the first mounting bracket 7 when the spring rebounds.

[0035] Further, a second through groove 81 parallel to the arc surface is provided at the arc surface of the second mounting bracket 8, and the upright column 9 is mounted in the second through groove 81. The arc surface of the upright column 9 extends outwards from the second through groove 81.

[0036] It should be noted that the second through groove 81 is provided to prevent the conveyor belt / conveyor chain from directly contacting the second mounting bracket 8 when the spring rebounds.

[0037] Further, a notch 82 is provided at the top of the second mounting bracket 8, and a mounting hole 83 is provided at the bottom of the second mounting bracket 8. A convex block 91 is provided at the bottom of the column 9. The column 9 passes through the notch 82, and the convex block 91 is in interference fit with the mounting hole 83 so that the column 9 is mounted on the second mounting bracket 8.

[0038] It should be noted that by providing the notch 82, the mounting hole 83 and the convex block 91, when installing the column 9, only the column 9 needs to be inserted into the notch 82, and then the worker can knock the convex block 91 of the column 9 into the mounting hole 83; on the contrary, when the column 9 needs to be disassembled, the worker can knock the convex block 91 out from the bottom of the mounting hole 83 upwards, so that the loading and unloading of the column 9 and the second mounting bracket 8 are facilitated.

[0039] Further, a tensioning wheel 11 and an elastic member 12 are further provided on the chassis 1. The tensioning wheel 11 is slidably connected to the chassis 1. One end of the elastic member 12 abuts against the tensioning wheel 11, and the other end of the elastic member 12 abuts against the chassis 1. The conveyor belt / conveyor chain 6 is wound around the first connecting wheel 3, the second connecting wheel 4, the third connecting wheel 5 and the tensioning wheel 11.

[0040] It should be noted that by providing the tensioning wheel 11 and the elastic member 12, the elastic member 12 maintains a spring force on the tensioning wheel 11, so as to ensure that the tensioning wheel 11 can tension the conveyor belt / conveyor chain 6. At the same time, the elastic member 12 is provided so that the conveyor belt / conveyor chain 6 has enough elongation to adapt to the deformation caused by compressing the spring.

[0041] Further, the conveying mechanism 2 is provided with one or more conveyor belts / conveyor chains 6 arranged parallel to each other vertically.

[0042] More specifically, multiple conveyor belts / conveyor chains 6 can ensure that the conveyor belts / conveyor chains 6 can cover both ends of the spring, preventing the spring from detaching from the conveyor belts / conveyor chains 6.

[0043] For those skilled in the art, various corresponding changes and deformations can be made according to the above-described technical solutions and concepts, and all such changes and deformations should fall within the protection scope of the claims of the present invention.
