Description

Technical Field

[0001] This utility model relates to the field of accumulating conveying technology, and in particular to a high-speed, medium-load push rod accumulating overhead chain conveyor. Background Technology

[0002] Rising labor costs will drive increasing automation across production lines. Conveying is the foundation of all automation; only through the automatic transport of workpieces between different workstations on the production line can automation be achieved. Therefore, my country's manufacturing industry has a significant demand for automated conveying equipment. Accumulating conveyors, as the name suggests, primarily function as conveyors, transferring workpieces from one location to another. Secondly, they have a buffering function, capable of holding a certain number of workpieces. Accumulating conveyors are generally used at loading stations on production lines and at stations where components are transported from branch lines to the main line.

[0003] Accumulating conveyors generally consist of the following main components: conveyor track, traction chain, accumulating trolley assembly, drive unit, tensioning device, stopper, diverting switch, merging switch, push rod assembly, slope catcher, signal generator, lubrication device, etc. The mainstream accumulating conveyor models on the market are divided into light-duty and heavy-duty types. Light-duty conveyors typically use a closed-rail double-hinged chain as the traction chain, while heavy-duty conveyors generally use a forged detachable chain from Weber Corporation (USA). In recent years, Cardan-type cross-hinged chains, with their unique structure and stability, have been frequently used in some medium and heavy-duty conveyor systems and are receiving increasing attention.

[0004] However, the trolleys that are paired with the cross chain conveyor are welded components, which have poor structural strength and quality stability. They are often damaged in case of accidents or the lifting claws cannot fall smoothly. If it is a forged chain, sufficient initial tension must be set to tighten the chain. Otherwise, the chain will creep (crawling) during operation. Therefore, we propose a high-speed medium-load push rod accumulation type suspended chain conveyor. Utility Model Content

[0005] The main purpose of this invention is to provide a high-speed, medium-load push-rod accumulating overhead chain conveyor. By incorporating an accumulating conveyor track unit and a branching track unit, it addresses the issue of the carrying trolley in a cross-chain conveyor, which, being a welded component, suffers from poor structural strength and quality stability, often resulting in accidental damage or failure of the lifting claw to descend smoothly. Furthermore, if it is a forged chain, sufficient initial tension must be set to tighten the chain; otherwise, the chain will exhibit creeping (crawling) behavior during operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The high-speed, medium-load push rod accumulating overhead chain conveyor includes an accumulating conveying track unit, as well as a traction track unit, a merging turnout unit, and a branch turnout unit.

[0008] The accumulation and conveying track unit includes an accumulation straight track component, an accumulation rail horizontal curved track component disposed inside the accumulation and conveying track unit, and an accumulation rail upper arched curved track component and an accumulation rail lower deflected curved track component disposed between the accumulation straight track component and the accumulation rail horizontal curved track component.

[0009] The branch turnout unit includes a straight-through branch turnout and a curved branch turnout. The straight-through branch turnout includes a left-out-right-in transmission straight rail and a right-out-left-in transmission straight rail. The curved branch turnout includes a curved left-out branch turnout component and a curved right-out branch turnout component. The curved right-out branch turnout component includes a second square steel traction rail, a second type steel traction rail disposed on the side of the second square steel traction rail and connected to the second square steel traction rail, and an adjusting component disposed between the second square steel traction rail and the second type steel traction rail.

[0010] Preferably, the accumulating straight track component includes an upper traction track, a lower load-bearing traction track disposed below the upper traction track, an intermediate bracket installed on the periphery of the upper traction track and the lower load-bearing traction track, and an end bracket installed at the ends of the upper traction track and the lower load-bearing traction track.

[0011] Preferably, the upper traction rail is made of Z-shaped steel and the lower load-bearing traction rail is an 8# channel steel structure.

[0012] Preferably, the traction rail unit is the same as the accumulation and conveying rail unit, and the upper traction rail and the lower load-bearing traction rail are replaced by Z-shaped steel sections.

[0013] Preferably, the merging turnout unit includes a straight merging turnout and a curved merging turnout; the straight merging turnout includes a straight left-entry merging turnout and a straight right-entry merging turnout; the curved merging turnout includes a curved left-entry merging turnout component and a curved right-entry merging turnout component; the curved right-entry merging turnout component includes a first steel traction rail, a first square steel traction rail installed on the side of the first steel traction rail and connected to the first steel traction rail, and a turnout tongue disposed between the first steel traction rail and the first square steel traction rail.

[0014] Preferably, the right-out-left-in straight rail includes two staggered chain-changing components, a chain-changing rail half-bracket disposed on the periphery of the two chain-changing components, and a turnout end bracket disposed at the end of the chain-changing component. The chain-changing component includes a chain-changing rail traction rail and a chain-changing rail curved rail installed at the end of the chain-changing rail traction rail.

[0015] Preferably, the adjusting component includes a cylinder installed on the side wall of the second type steel traction rail and a fork tongue connector installed on the side wall of the second square steel traction rail and movably connected to the telescopic end of the cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, the accumulation conveyor track unit and branch switch unit combine the advantages of two types of conveyors: a cross chain for the traction chain and a forged chain for the carrying trolley. A proprietary, non-standard track system, the "wide push rod" system, is developed to complement this system, giving the entire accumulation chain system higher reliability and flexibility. The application of the wide push rod accumulation conveyor fundamentally improves the transfer method of the accumulation trolley, simplifying the original two-stage backward rail pressing transfer to a single side-push transfer, shortening the transfer time, accelerating the production cycle, and making the accumulation conveyor layout more compact. This significantly improves the effective utilization rate of the process line, prevents the lifting claw from failing to fall smoothly, and avoids chain creep during operation.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] Example 1

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, the high-speed medium-load push rod accumulating overhead chain conveyor includes an accumulating conveying track unit 1, as well as a traction track unit, a merging turnout unit, and a branch turnout unit.

[0034] like Figure 1-4 As shown, the accumulation and conveying track unit 1 includes an accumulation straight track component 101, an accumulation rail horizontal curved track component 104 disposed inside the accumulation and conveying track unit 1, an accumulation rail upper arched curved track component 102 and an accumulation rail lower deflected curved track component 103 disposed between the accumulation straight track component 101 and the accumulation rail horizontal curved track component 104. The accumulation rail upper arched curved track component 102, the accumulation rail lower deflected curved track component 103 and the accumulation rail horizontal curved track component 104 are structurally identical to the accumulation straight track component 101, except for the bending angle.

[0035] like Figure 6 and Figure 7As shown, the branch turnout unit includes a straight-through branch turnout and a curved branch turnout. The straight-through branch turnout includes a left-out-right-in transmission straight rail and a right-out-left-in transmission straight rail 3. The curved branch turnout includes a curved left-out branch turnout component and a curved right-out branch turnout component 4. The curved right-out branch turnout component 4 includes a second square steel traction rail 401, a second type steel traction rail 402 located on the side of the second square steel traction rail 401 and connected to the second square steel traction rail 401, and an adjusting component 403 located between the second square steel traction rail 401 and the second type steel traction rail 402. In the accumulation and conveying system, the branch turnout unit can divide one line into two lines. Because the branch turnout needs to complete the chain change transmission, the rail spacing of each inlet and outlet section of the turnout is 209mm. At this rail spacing, the push head is not restricted by the overflow pawl and is higher than the overflow pawl. As for the lifting pawl engagement.

[0036] like Figure 1 As shown, the accumulating straight track component 101 includes an upper traction track 1011, a lower supporting traction track 1012 disposed below the upper traction track 1011, an intermediate bracket 1013 installed on the peripheral sides of the upper traction track 1011 and the lower supporting traction track 1012, and an end bracket 1014 installed at the ends of the upper traction track 1011 and the lower supporting traction track 1012. The end bracket 1014 and the intermediate bracket 1013 allow for tight installation of the upper traction track 1011 and the lower supporting traction track 1012. The standard length of the accumulating straight track component 101 is 6000mm, and non-standard length tracks (<6mm) are also available depending on the track location. The 102 and 103 upper arched and curved rail components of the accumulation rail are used for sloping sections of the track, with a rail spacing of 164mm. The 104 horizontal curved rail component of the accumulation rail is used for horizontal turns in the accumulation rail system. The radius and angle vary depending on the location. In this system, the rail radius is R1000, R900, and R800; the angles are 30°, 45°, and 90°. The R1000 radius horizontal curved rail is mainly used for curved sections of the main line, the R900 radius horizontal curved rail is used for locations with limited interlayer space, and the R800 radius horizontal curved rail is mainly used for docking with turnouts. Unlike the vertical curved rail, the rail spacing of the horizontal curved rail is the standard rail spacing of 194mm.

[0037] like Figure 1 As shown, the upper traction rail 1011 is made of Z-shaped steel, and the lower load-bearing traction rail 1012 is an 8# channel steel structure. The Z-shaped steel, square steel and the 8# channel steel of the load-bearing rail are all made of 16Mn.

[0038] like Figure 1-4 As shown, the traction rail unit is the same as the accumulation and conveying rail unit 1, and the upper traction rail 1011 and the lower bearing traction rail 1012 are replaced by Z-shaped steel sections. The traction curved rail is composed of four 40 square steel concentric curved rails.

[0039] like Figure 5 As shown, the merging turnout unit includes a straight-through merging turnout and a curved merging turnout. The straight-through merging turnout includes a straight-through left-entry merging turnout and a straight-through right-entry merging turnout. The curved merging turnout includes a curved left-entry merging turnout component and a curved right-entry merging turnout component 2. The curved right-entry merging turnout component 2 includes a first type steel traction rail 201, a first square steel traction rail 202 installed on the side of the first type steel traction rail 201 and connected to the first type steel traction rail 201, and a turnout tongue 203 set between the first type steel traction rail 201 and the first square steel traction rail 202. The merging turnout unit can merge two lines into one line. Because the merging turnout needs to complete the chain change transmission, the rail spacing of each inlet and outlet section of the turnout is 209mm. At this rail spacing, the push head is not restricted by the overflow claw and is higher than the overflow claw. As for the lifting claw engagement.

[0040] like Figure 6 As shown, the right-out-left-in straight rail 3 includes two staggered chain-changing components 301, a chain-changing rail half-bracket 302 disposed on the periphery of the two chain-changing components 301, and a turnout end bracket 303 disposed at the end of the chain-changing component 301. The chain-changing component 301 includes a chain-changing rail traction rail 3011 and a chain-changing rail curved rail 3012 installed at the end of the chain-changing rail traction rail 3011. The chain-changing rail half-bracket 302, the intermediate bracket 1013 and the end bracket 1014, etc., are all made of Q235-A material.

[0041] It combines the advantages of two types of conveyors: the traction chain uses a cross chain, and the carrying trolley uses a forged chain accumulation chain. A proprietary non-standard track system and a "wide push rod" system have been developed to match it, which makes the entire accumulation chain system more reliable and flexible.

[0042] Example 2

The accumulation rail upper arched curved track component 102, the accumulation rail lower deflected curved track component 103 and the accumulation rail horizontal curved track component 104 are structurally identical to the accumulation straight track component 101, except for the bending angle.

[0045] like Figure 6 and Figure 7 As shown, the branch turnout unit includes a straight-through branch turnout and a curved branch turnout. The straight-through branch turnout includes a left-out-right-in transmission straight rail and a right-out-left-in transmission straight rail 3.

In the accumulation and conveying system, the branch turnout unit can divide one line into two lines. Because the branch turnout needs to complete the chain change transmission, the rail spacing of each inlet and outlet section of the turnout is 209mm. At this rail spacing, the push head is not restricted by the overflow pawl and is higher than the overflow pawl. As for the lifting pawl engagement.

[0046] like Figure 1 As shown, the accumulating straight track component 101 includes an upper traction track 1011, a lower supporting traction track 1012 disposed below the upper traction track 1011, an intermediate bracket 1013 installed on the peripheral sides of the upper traction track 1011 and the lower supporting traction track 1012, and an end bracket 1014 installed at the ends of the upper traction track 1011 and the lower supporting traction track 1012. The end bracket 1014 and the intermediate bracket 1013 allow for tight installation of the upper traction track 1011 and the lower supporting traction track 1012. The standard length of the accumulating straight track component 101 is 6000mm, and non-standard length tracks (<6mm) are also available depending on the track location. The 102 and 103 upper arched and curved rail components of the accumulation rail are used for sloping sections of the track, with a rail spacing of 164mm. The 104 horizontal curved rail component of the accumulation rail is used for horizontal turns in the accumulation rail system. The radius and angle vary depending on the location. In this system, the rail radius is R1000, R900, and R800; the angles are 30°, 45°, and 90°. The R1000 radius horizontal curved rail is mainly used for curved sections of the main line, the R900 radius horizontal curved rail is used for locations with limited interlayer space, and the R800 radius horizontal curved rail is mainly used for docking with turnouts. Unlike the vertical curved rail, the rail spacing of the horizontal curved rail is the standard rail spacing of 194mm.

[0047] like Figure 1 As shown, the upper traction rail 1011 is made of Z-shaped steel, and the lower load-bearing traction rail 1012 is an 8# channel steel structure. The Z-shaped steel, square steel and the 8# channel steel of the load-bearing rail are all made of 16Mn.

[0048] like Figure 1-4 As shown, the traction rail unit is the same as the accumulation and conveying rail unit 1, and the upper traction rail 1011 and the lower bearing traction rail 1012 are replaced by Z-shaped steel sections. The traction curved rail is composed of four 40 square steel concentric curved rails.

[0049] like Figure 5 As shown, the merging turnout unit includes a straight-through merging turnout and a curved merging turnout. The straight-through merging turnout includes a straight-through left-entry merging turnout and a straight-through right-entry merging turnout. The curved merging turnout includes a curved left-entry merging turnout component and a curved right-entry merging turnout component 2. The curved right-entry merging turnout component 2 includes a first type steel traction rail 201, a first square steel traction rail 202 installed on the side of the first type steel traction rail 201 and connected to the first type steel traction rail 201, and a turnout tongue 203 set between the first type steel traction rail 201 and the first square steel traction rail 202. The merging turnout unit can merge two lines into one line. Because the merging turnout needs to complete the chain change transmission, the rail spacing of each inlet and outlet section of the turnout is 209mm. At this rail spacing, the push head is not restricted by the overflow claw and is higher than the overflow claw. As for the lifting claw engagement.

[0050] like Figure 6 As shown, the right-out-left-in straight rail 3 includes two staggered chain-changing components 301, a chain-changing rail half-bracket 302 disposed on the periphery of the two chain-changing components 301, and a turnout end bracket 303 disposed at the end of the chain-changing component 301.

[0051] like Figure 8 As shown, the adjusting component 403 includes a cylinder 4031 installed on the side wall of the second type steel traction rail 402 and a turnout tongue connector 4032 installed on the side wall of the second square steel traction rail 401 and movably connected to the telescopic end of the cylinder 4031. The merging turnout is realized by mechanical structure, while the branch turnout requires pneumatic assistance, i.e., the cylinder 4031, to realize the adjustment of the branch angle.

[0052] The application of wide push rod accumulating conveyors has fundamentally improved the transfer method of accumulating trolleys, simplifying the original two-stage backward rail pressing transfer to a single side push transfer, shortening the transfer time, accelerating the production cycle, and making the layout of the accumulating conveyor more compact. It has significantly improved the effective utilization rate of the process line, prevented the lifting claw from failing to fall smoothly, and avoided the phenomenon of chain creep during operation.
