Method of using an anti-slip accumulation chain structure

Abstract

This invention relates to the field of automotive painting technology and discloses an anti-slip accumulation chain structure, comprising several interconnected transmission chains. One transmission chain is connected to a straightening support wheel. Several standard support wheels connected to the transmission chain are located on both sides of the straightening support wheel. The straightening support wheel, in conjunction with the standard support wheels, abuts against the bottom surface of a skid to support the skid and the vehicle body on top of the skid. The diameter of the straightening support wheel is larger than the diameter of the standard support wheels, with the difference not exceeding 2 mm. Compared with existing technologies, this application, by adjusting and optimizing the local support wheel structure of the anti-slip accumulation chain, changes the original pure friction driving mode to a combination of thrust and friction to achieve effective skid movement. This effectively avoids skid slippage caused by wear of the standard support wheels and skid deformation, ensuring effective skid movement and thus achieving effective transmission of the vehicle body.

Description

Technical Field

[0001] This invention relates to the field of automotive coating technology, and in particular to a method of using an anti-slip stacking chain structure. Background Technology

[0002] The automotive painting line production process requires the establishment of storage areas to form buffers in each process section, such as electrophoresis storage area, intermediate coating storage area, topcoat storage area, spot repair storage area, PBS storage area, etc. Since the buffer time in each storage area is different, a different number of anti-slip stacking chain structures are set up to store the car body. The car body is fixed on the skid and then placed on top of several anti-slip stacking chain structures. The support wheels of each anti-slip stacking chain structure abut against the skid and drive the skid to move continuously along the production line.

[0003] Under normal circumstances, for the anti-slip accumulation chain structure to drive the skid (skid length L) forward, at least 2L / 3 support wheels need to be in contact with the skid simultaneously. In actual use, the support wheels of the anti-slip accumulation chain structure will also wear due to prolonged contact and friction with the skid. At this time, the height of the contact surface between the worn support wheel and the skid is uneven. When the number of support wheels in contact with the skid at the same time is less than L / 3, the friction force provided by the support wheels to the skid is insufficient, causing the skid to slip. The skid cannot move forward normally, resulting in conveying timeout. In severe cases, manual pushing is required to ensure the movement of the skid, affecting the normal production of the production line. In addition, after the skid is baked at high temperature in the drying oven, it enters the storage area. The sudden temperature change will also cause the skid to deform due to thermal expansion and contraction. Obviously, the deformation of the skid will also cause a height difference between it and the support wheel, which will also cause the skid to slip. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the purpose of this invention is to provide an anti-slip accumulation chain structure, which will...

[0005] Based on this, the present invention provides an anti-slip accumulation chain structure, which includes several interconnected transmission chains, one of which is connected to a straightening support wheel. Several standard support wheels connected to the transmission chain are provided on both sides of the straightening support wheel. The straightening support wheel cooperates with the standard support wheels to abut against the bottom surface of the skid to support the skid and the body of the skid top. The diameter of the straightening support wheel is larger than the diameter of the standard support wheel.

[0006] In some embodiments of this application, at least one of the skids is arranged between two adjacent corrective support wheels.

[0007] In some embodiments of this application, at least six standard support wheels are provided between two adjacent corrective support wheels.

[0008] In some embodiments of this application, the corrective support wheel is formed by a bushing fitted over the standard support wheel, and the standard support wheel and the bushing are detachably connected.

[0009] In some embodiments of this application, the thickness of the bushing is 0.75-1mm.

[0010] The anti-slip stacking chain structure provided in this invention has the following advantages compared with the prior art:

[0011] This invention provides an anti-slip accumulation chain structure, comprising several interconnected transmission chains. One transmission chain is connected to a straightening support wheel. Several standard support wheels, connected to the transmission chain, are located on both sides of the straightening support wheel. The straightening support wheel, in conjunction with the standard support wheels, rests against the bottom surface of a skid to support the skid and the car body on top of the skid. The diameter of the straightening support wheel is larger than the diameter of the standard support wheels, with the difference not exceeding 2 mm. Based on this structure, when the anti-slip accumulation chain structure is complete, the operator can drive the straightening support wheel and the standard support wheels to move continuously along the production line via the transmission chain. The skid used to set the car body is supported by the straightening support wheel and the standard support wheels. It should be noted that this application uses several standard support wheels, with each skid having at least two standard support wheels at its bottom. When the sled structure is not deformed or the standard support wheels are not worn, the standard support wheels stably abut against the sled and drive the sled forward. When the sled is deformed or the standard support wheels are worn, some of the standard support wheels cannot effectively abut against the sled. At this time, the pressure exerted by the sled on each support wheel is insufficient, and the friction force exerted by the standard support wheels on the sled is also reduced accordingly. Relative sliding occurs between the sled and the standard support wheels. The standard support wheels move forward with the transmission chain, while the sled stops in place due to slippage. As the transmission chain continues to move forward, the straightening support wheel located behind the sled continuously approaches... Because the diameter of the straightening support wheel is larger than that of the standard support wheel, the straightening support wheel eventually impacts the rear end of the skid. At this point, the straightening support wheel provides a thrust to the skid, causing the slipping skid to continue sliding along the production line. The straightening support wheel, after impacting the skid, continues to move to the bottom of the skid and, together with other standard support wheels, supports the skid to form a new frictional balance, allowing the skid and the transmission chain to maintain synchronized and uniform speeds again. It should be further noted that when the thrust provided by the straightening support wheel to the skid is small, the straightening support wheel can still press against the rear end of the skid and drive the skid to continue moving. Thus, this application, by adjusting and optimizing the local support wheel structure of the anti-slip accumulation chain, changes the original pure frictional drive mode to a combination of thrust and friction to achieve effective skid movement. This effectively avoids skid slippage caused by wear of the standard support wheel and skid deformation, ensuring effective skid movement and thus achieving effective transmission of the vehicle body.

[0018] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0019] It should be understood that the terms "before," "after," etc., are used in this invention to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, "before" information can also be called "after" information, and "after" information can also be called "before" information, without departing from the scope of this invention.

[0020] like Figures 1 to 5 As shown, the present invention provides an anti-slip accumulation chain structure, which includes several interconnected transmission chains 1, one of which is connected to a straightening support wheel 2. Several standard support wheels 3 connected to the transmission chain 1 are provided on both sides of the straightening support wheel 2. The straightening support wheel 2 cooperates with the standard support wheels 3 to abut against the bottom surface of the skid 5 to support the skid 5 and the body 6 on the top of the skid 5. The diameter of the straightening support wheel 2 is larger than the diameter of the standard support wheel 3 and the difference between the two is not greater than 2mm.

[0021] Based on the above structure, when the anti-slip accumulation chain structure is completed, the operator can drive the straightening support wheel 2 and the standard support wheel 3 to move continuously along the production line via the transmission chain 1. The skid 5 used to set the car body 6 is placed on top of the straightening support wheel 2 and the standard support wheel 3 and is supported by them. It should be explained that there are several standard support wheels 3 in this application, and each skid 5 has at least two standard support wheels 3 at its bottom. When the skid 5 structure is not deformed or the standard support wheels 3 are not worn, the standard support wheels 3 stably abut against the skid 5 and drive the skid 5 forward. When the skid 5 is deformed or the standard support wheels 3 are worn, some of the standard support wheels 3 cannot effectively abut against the skid 5. At this time, the pressure of the skid 5 on each support wheel is insufficient, and the friction of the standard support wheels 3 on the skid 5 is also reduced accordingly. Relative sliding occurs between the skid 5 and the standard support wheels 3. The standard support wheels 3 move forward with the transmission chain 1, while the skid 5 stops in place due to slippage. As the transmission chain 1 continues to move forward, the straightening support wheel 2 located behind the skid 5 continuously approaches. Because the diameter of the straightening support wheel 2 is larger than that of the standard support wheel 3, the straightening support wheel 2 eventually impacts the rear end of the skid 5. At this point, the straightening support wheel 2 can provide a thrust to the skid 5, causing the slipping skid 5 to continue sliding along the production line. The straightening support wheel 2, which impacts the skid 5, continues to move to the bottom of the skid 5 and together with the other standard support wheels 3, supports the skid 5 to form a new frictional balance, so that the speed of the skid 5 and the transmission chain 1 are synchronized and move forward at a constant speed again. It should be further noted that when the thrust provided by the straightening support wheel 2 to the skid 5 is small, the straightening support wheel 2 can also abut against the rear end of the skid 5 and drive the skid 5 to continue moving. In this way, by adjusting and optimizing the local support wheel structure of the anti-slip accumulation chain structure, this application changes the original pure friction driving mode to a combination of thrust and friction to achieve effective movement of the skid 5, effectively avoiding the skid 5 slippage problem caused by the wear of the standard support wheel 3 and the deformation of the skid 5, ensuring the effective movement of the skid 5, and thus achieving effective transmission of the car body 6. In addition, to avoid the anti-slip accumulation chain stopper being unable to open due to the excessive size of the straightening support wheel 2, which would affect normal conveying, the diameter difference between the straightening support wheel 2 and the standard support wheel 3 in this application should be 1.5mm-2mm.

[0022] Furthermore, for the straightening support wheel 2 of this application, the spacing of its arrangement is determined by the coordination of the length of the skid 5 and the production cycle. During production, the anti-slip accumulation chain structure operates continuously without gaps. The standard support wheel 3 spacing of the anti-slip accumulation chain structure is 800mm. In some embodiments of this application, the length of the skid 5 is preferably 5000mm (at this time, six standard support wheels 3 need to be in contact, that is, at least six standard support wheels 3 are provided between two adjacent straightening support wheels 2). The production cycle is 48 JPH, and the chain speed of the transmission chain 1 of the anti-slip accumulation chain structure is 4.5m / min. Therefore, in order to prevent the skid 5 from slipping, the spacing of the straightening support wheels 2 is 5600mm (one straightening support wheel 2 is arranged at least six standard support wheels 3 apart). In some other embodiments of this application, the chain speed of the anti-slip accumulation chain structure is greater than 5 m / min. In this case, the spacing of the straightening support wheels 2 should be increased by an integer multiple of the length L of the skid 5, where n is 1-3. If the value is too large, the skid 5 may slip, causing the compensation time to fail to meet the production cycle requirements. It should be noted that the straightening support wheels 2 must be arranged in integer multiples of the accumulation pitch. It is not advisable to have more than two straightening support wheels 2 in one pitch. Too many straightening support wheels 2 may lead to new poor contact or excessive contact, which may easily cause abnormal noise in the operation of the anti-slip accumulation chain structure, or even accelerate the wear of the support wheels and the longitudinal beam of the skid 5, or cause the anti-slip accumulation chain structure stopper to fail to open due to excessive friction, affecting normal conveying. That is, at least one skid 5 should be provided between two adjacent straightening support wheels 2.

[0023] Furthermore, in some embodiments of this application, the straightening support wheel 2 is formed by a standard support wheel 3 with a bushing 4 fitted over it, and the standard support wheel 3 and the bushing 4 are detachably connected. This ingenious structural design of the straightening support wheel 2 facilitates assembly. When the straightening support wheel 2 becomes worn, the operator can replace it with a new bushing 4 to update the straightening support wheel 2. Based on the foregoing description, the thickness of the bushing 4 in this application is preferably 0.75-1mm.

[0024] In summary, this invention provides an anti-slip accumulation chain structure, comprising several interconnected transmission chains 1, one of which is connected to a straightening support wheel 2. Several standard support wheels 3, connected to the transmission chains 1, are located on both sides of the straightening support wheel 2. The straightening support wheel 2, in conjunction with the standard support wheels 3, abuts against the bottom surface of a skid 5 to support the skid 5 and the vehicle body 6 on top of the skid 5. The diameter of the straightening support wheel 2 is larger than the diameter of the standard support wheels 3, with the difference not exceeding 2 mm. Compared with the prior art, this application, by adjusting and optimizing the local support wheel structure of the anti-slip accumulation chain, changes the original pure frictional driving mode to a combination of thrust and friction to achieve effective movement of the skid 5. This effectively avoids the skid 5 slippage problem caused by wear of the standard support wheels 3 and deformation of the skid 5, ensuring the effective movement of the skid 5 and thus achieving effective transmission of the vehicle body 6.

[0025] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
