Abstract

The biggest advantage of upright thrust actuator technology is that it exerts a strong force at the lowest point of the device, generating thrust in the chain and raising heavy objects without difficulty to the device. The rigidity and directionality of the upright chain and the flexible characteristics of the multi-joints can exert great force when combined with the hydraulic operating cylinder (13-1). The upright thrust actuator is a technology that generates powerful upward thrust by combining the guide that guides the chain, the direction change round, and the operating cylinder. The upward thrust actuator, which consists of the upright chain, chain guide, direction change round, and operating cylinder, is horizontal (X direction). This is a technology for an upright thrust actuator that converts linear motion into upward motion in the vertical direction (Y direction) using a direction change round and at the same time generates strong thrust on the upright chain.

Description

Upright thrust actuator using chain direction conversion and upward thrust device using the same {Upright thrust actuator using chain direction conversion and upward thrust device using the same}

It is an upright thrust actuator technology that utilizes the rigidity and directionality of an upright chain and the flexible characteristics of a multi-joint chain. It combines the guides (20, 30) that guide the chain and the direction change round (17) with the operating cylinder (13) to create a powerful upward thrust. As a technology, the operating cylinder converts linear motion into upward motion in the vertical direction (Y direction) using a direction change round (17) and at the same time generates strong thrust in the upright chain to lift heavy objects or control the position of the lift. An upright thrust actuator that is used as an actuator or as a shock absorber or shock absorber that absorbs shock and restores the position by filling and sealing the inside of the operating cylinder with elastic members such as gas, springs, and magnets. It is a technology for

An upright chain is a chain that bends on one side but maintains rigidity on the other. Upright chains are actively used in various industrial fields, the representative field of which is a device that uses the thrust of the chain, such as lifts and table lifts, and uses power such as a motor and reducer on the sprocket to convert the rotational motion of the sprocket into linear motion. This is used as the principle by which thrust is generated.

Unlike these technologies, the present invention is a technology that transmits the strong thrust of the operating cylinder to the chain, rather than the rotational movement of the sprocket, and generates strong upward thrust by using the direction change round of the linear motion acting on the chain.

Hydraulic operating cylinders are small and light and can produce large output, but when used for lifts or lifting devices such as [A] in [Figure 1], it is difficult to use them as direct thrust due to the space efficiency that occupies the length of the main body of the cylinder (13). The table is raised by indirect thrust using the mold support (38). In order to improve the low space efficiency of the hydraulic operating cylinder, the table lift currently being commercialized operates by indirect thrust by installing scissor-type supports (38) on the upper plate (100) and lower plate (101) and attaching them to the scissor-type transfer supports. Devices dominate. This scissors-type indirect thrust device (A in FIG. 1) has many problems. When the top plate 100 of the table lift is lowered to the lowest point, the scissors lie almost horizontally. If the scissors are laid down further to lower the minimum height, the angle of the scissors with the ground becomes too small, which creates too much load on the hydraulic cylinder and scissors during the initial rise.

Therefore, in general, when manufacturing a table lift, a certain angle is given so that the scissors do not lie down even if the top plate is lowered to the lowest point.

Due to this problem, the scissor-type indirect thrust device has many limitations in lowering the bottom of the table because it must maintain the minimum folding angle that operates on the scissors using a hydraulic cylinder. To solve such problems, [Figure 1 [B]] and Direct thrust using the same upright chain (11) has been proposed as an alternative and is widely used in lifts and hoisting devices. However, a direct thrust device using an upright chain generates power with a motor and a reducer (19) on the sprocket, so a large motor and a large reducer (19) are needed to generate large force.

In order to lift a large load, a large torque must be transmitted to the sprocket, but the motor capacity and capacity of the reducer must be increased, so as the reducer becomes larger, space efficiency decreases. The cost of the reducer is also expensive, so although it has many functional advantages, the upright chain motor device remains in the expensive market, making it burdensome to use.

To solve these problems, we propose an upright thrust actuator technology that combines an operating cylinder and a chain, as shown [[C] in Figure 1).

In the examples illustrating the present invention, chain refers to an upright chain.

An upright chain is a chain with rigid, directional, and flexible characteristics that is freely wound and collected on one side and used flexibly, but forms a rigid bar-shaped column that maintains rigidity in the opposite direction.

[[C] in Figure 1] arranges the operating cylinder in the direction in which the chain moves, so that the thrust of the operating cylinder can be used to the maximum, thereby increasing space efficiency and usage efficiency.

The horizontal arrangement of the operating cylinder is compared with the technologies A and B in Figure [1], which are being commercialized by lowering the lowest point of the device.

In the present invention, as shown in [Figure 7], the upright chain (11) is placed on the guides (20, 30) and the end of the upright chain is pushed to the operating cylinder (13) to change the direction of the chain from horizontal (X) to vertical (Y). As an example, the upright thrust actuator technology, which acts to raise objects or objects with the strong thrust generated at this time, is presented as an example.

The guide that guides the chain of the present invention is divided into a horizontal (X-direction) guide and a vertical (Y-direction) guide. It can be manufactured by cutting or attaching to a groove or uneven rail, linear guide, or various other shapes. . The force that starts in the horizontal direction (30) of the operating cylinder (13) changes direction through the direction change round (17) to the vertical direction (20) guide and generates thrust.

Hydraulic cylinders (13-1) have the advantage of generating large torque with small fluid force.

The piston shaft (35) of the hydraulic cylinder operates the upright chain by pushing the guide block (15) connected to the upright chain with strong force. The greatest advantage of upright thrust actuator technology is that it generates strong force at the lowest point of the device.

That is, the force applied to the upright chain 11 on the horizontal guide 30 to the piston shaft 35 of the operating cylinder 13 is thrust to the Y-direction guide 20 along the guide surface of the direction change round 17. It happens.

At this time, the operating cylinder may be composed of hydraulic pressure, pneumatic pressure, electricity, magnetic field, etc. Looking at the power of the operating cylinder in detail, electric refers to an electric cylinder consisting of an electric motor and a reducer, and the magnetic field uses the N and S poles of the magnet to create a magnetic field block at the end of the upright chain and arrange the magnet to create a powerful magnetic force. It can be used in small automated devices that do not require large power to push the chain.

Magnetic field technology using electricity consists of forming a silicon steel core around the path along which the chain moves, that is, the chain guide, wrapping a coil around the core, placing the chain so that it passes through the central tunnel of the coil, and then placing the coil. When a strong magnetic field is generated, the strong magnetic field is transferred to the internal chain according to Fleming's left-hand rule, and the magnetic field becomes a solenoid device that strongly pushes or pulls the chain. At this time, the chain is directed along the guide (30). A technology that generates thrust in the up and down direction (20) after switching is presented as an example.

There are also hydraulic cylinders using oil or fluid, pneumatic cylinders using air, and electric cylinders consisting of motors and reducers using AC or DC power.

Commercially available upright chains generally generate thrust by converting the rotational motion of the sprocket into linear motion, but in the present invention, the purpose of the sprocket is not to transmit power by converting rotational motion into linear motion, but to simply change direction. It has the feature of being built-in.

The greatest advantage of the operating cylinder is that it exerts a large force using a small medium such as fluid or air, and the greatest advantage of the upright thrust actuator (12) technology of the present invention is that the torque of the cylinder is reduced by horizontally arranging the operating cylinder with an upright chain. It can transmit the maximum value to the chain and lower the lowest point of the device to generate upward thrust with strong direct thrust force.

The upright thrust actuator (12), which combines the operating cylinder and the upright chain, generates a strong upward thrust on the chain and can be configured simply, and the simple design of the direction change round (17) can generate highly efficient upward thrust. there is. The device has a simple configuration and has the advantage of generating constant torque and highly efficient torque even at the lowest point of the device.

All illustrations of the present invention are presented by briefly drawing only the main points to aid understanding of the embodiments. The illustrated illustrations are not complete in explaining the entire technology of the present invention, and the parts that are insufficient in the illustrations as a brief explanation of the embodiments must be implemented. I would like to explain it as a detailed description of the example.

Our own research confirmed that the characteristic of the upright chain (11) is that the compressive load is about twice as high as the tensile load.

In other words, it means that the upright chain has greater strength and durability when used by pushing and compressing it rather than pulling it. When using an upright chain by pulling and pushing, there is no need for a guide or support to guide the chain as long as it is pulled and pushed in a straight line. However, in order to change the direction of the chain and use it, a guide (20,30) must be constructed to guide the chain's path.

The chain also includes separate parts (10) such as rollers and bearings to allow the guide to move while sliding smoothly. At the end of the chain, a guide block (15) is formed that connects the chain and the piston shaft (35). The guide block (15) transmits the strong force generated by the piston shaft (35) to the chain (11) without loss. It plays a role.

The guide block 15 is composed of sliding parts such as rollers and bearings 10 and is configured to move along the guides 20 and 30 like a train running on rails.

Figure [1] shows the performance of the upright thrust actuator, which is an embodiment of the invention, and the commercial technology.

This is a comparative understanding.

Figures [A], [B], and [C] in Figure 1 compare the minimum height of the table lift assuming a load of 1000 kg.

[A] is a table consisting of a hydraulic cylinder (13-1) on a scissor-type support (38)

It is a lift, and [B] is an upright chain thrust table lift that uses a motor and a reducer (19) on the upright chain (11) to apply thrust to the upright chain using the rotational force of the sprocket.

[C] combines the upright chain (11), which is a technology of the present invention, with the hydraulic cylinder (13-1) and pushes the chain with the force of hydraulic pressure (13-1), so that the chain changes direction along the guide (30) and moves up and down. It is a lifting device that generates thrust.

In the figure, it can be seen that the minimum height (75) of [C] is significantly lower than the minimum height (73) of figure [A] and the minimum height (74) of [B] in [Figure 1]. The operating cylinder is connected to the chain. By placing it horizontally or within 15 degrees in the Y+ direction and 45 degrees in the Y-direction from the center line of the guide, the strong torque of the cylinder can be used to the fullest and the minimum height of the device can be used significantly lower.

Figure [2] is a diagram showing an example of an upright thrust actuator consisting of an upright chain (11), a main body (12) composed of guides (20, 30), and an operating cylinder (13).

The chain can be constructed by attaching a pair of rollers on each side to slide the guide.

The link plate of an upright chain consists of an outer link plate attached to the outside of the chain unit and an inner link plate forming the chain unit on the inside. The outer link plate and the inner link plate are connected by roller pins, and the number corresponding to a certain length is repeatedly assembled to complete the upright chain.

The link plate and the connecting pin on the outside engage with each other to form a right angle and keep the chain upright. On one side, it bends and winds well, but on the other side, it is a strong, rod-shaped rigid chain of a certain length.

[A] in Figure [3] is an example explaining the change in direction of an upright chain and force, and is a diagram showing the process of changing direction as the upright chain (11) passes through the direction change guide (17), and [B] is a change in direction. This figure shows an explanation of the moment of force in a round.

When force (F1) is applied to the upright chain in [A], the sliding roller (10) of the upright chain slides and moves forward along the guide (30).

At this time, the direction of force received by the roller 10 located in the direction change guide 17 is the piston shaft 35 F1 when the radius of the round 17 is F0, the X direction force is F1, and the Y direction force is F2. The force applied acts in a 45-degree direction that bisects the distance F0 from the center point of the round (17) to the round (17) and the direction of force F1 of the piston shaft (35). The rollers 10 sliding the guides 20 and 30 act in a direction of 45 degrees, which is the bisector of forces F0 and F1 or F0 and F2, and slide along the direction change round 17.

The size of the force required at this time is the angle formed between the center line of the round and the direction of the force.

It can be obtained using sin θ, cos θ, and tan θ.

B in Figure [3] is a diagram showing the moment of force at a point passing through the change of direction round (17).

The moment of force in the X direction (72) and the moment of force in the Y direction (71) act so that the force acts in the direction of F1.

When force F2 and force F1, which act in opposite directions, meet in the direction change round (17), the stronger of the two forces acts as the elapsed value, and the upright chain moves in the direction in which the direction of the force is greater. For example, if force F2 is greater than force F1 by force FX, the upright chain moves in the direction of F2 at the magnitude of force FX.

Conversely, if force F1 is greater than force F2 by force FX, it rises in the direction of F1 by the amount of force FX.

The arrangement angle of the operating cylinder is arranged horizontally around the ) is placed within 15 degrees in the Y+ direction and 45 degrees in the Y-direction from the center line of the guide, which is composed of a Features:

At this time, various fixing methods such as pins, bolts, hinge pins, and welding may be used.

[A] in Figure [4] shows that when the piston shaft 35, which advances by the electric cylinder 13, pushes the guide block 15 or the chain in the X direction, the chain goes through a direction change round 17 by thrust. It changes direction in the vertical (Y) direction and moves forward, generating thrust. At this time, the operating cylinder 13 is configured to easily rotate, such as a hinge 34, and may be fixed by a fastening part or fixed to a fixing block 37 with a bolt or hinge pin to prevent it from moving.

As in the example in Figure [4], the operating cylinder 13 determines the position where the hinge 34 is fixed in order to generate strong thrust. As shown in B in Figure [4], the position of the hinge 34 is installed lower than the guide. You can.

The chain guide block 15 in Figure [4] is connected to the piston shaft 35, and a sliding means corresponding to a guide such as a roller may be attached so that it can move smoothly along the guide.

The chain guide block is located where the link of the last chain and the guide block meet.

It can be assembled by processing the guide block in the shape of a chain's link plate so that the side of the link plate and the side of the guide block are in close contact with each other.

In the present invention, the block 37 for fixing the hinge 34 can be configured horizontally at the same height as the guide or lower than the guide to increase the stroke distance of the shaft.

Additionally, in order to generate strong thrust in the chain and increase the chain's braking ability, the position of the hinge block 37 may be configured to be higher than the guide 30.

As in the example in Figure [4], the operating cylinder 13 may be configured to move freely in conjunction with the chain, or the cylinder may be fixed so that it does not move horizontally with the chain guide using a bracket, etc.

It is characterized in that the linear motion (X direction) of the upright chain is converted into vertical movement (Y direction) by the direction change round due to the thrust.
