Hereinafter, the most preferred embodiments of the present invention will be described in detail in order to enable those skilled in the art to easily practice the present invention.

Numbers cited in the examples below are not limited to the objects of citation and can be applied to all examples. An object that has the same purpose and effect as the configuration presented in the examples is an equivalent replacement object. The high-level concept presented in the examples includes low-level concept objects that are not described.

[Example 1-1] The present invention relates to a transfer device, and specifically includes a main body 100 with a space formed therein; An internal transfer body 200 that reciprocates within the main body; An actuator 300 that provides power to the internal transporter; It includes an external transporter 400 located outside the main body and transported in conjunction with the internal transporter.

[Example 1-2] The present invention relates to a transfer device, and in Example 1-1, the main body is box-shaped and forms a closed space therein.

[Example 1-3] The present invention relates to a transfer device, and in Example 1-1, it includes a temperature and humidity sensor 121 located inside the main body and detecting humidity and temperature.

[Example 1-4] The present invention relates to a transfer device, and in Example 1-3, a temperature and humidity controller 122 that detects the temperature and humidity sensor signal and controls a dehumidifying device and a temperature device inside the main body; Includes.

[Example 1-5] The present invention relates to a transfer device, and in Example 1-3, the temperature device includes a Teltier element 123a; and/or a heating heater (123b).

The present invention relates to a transfer device used in a high humidity and low temperature environment. High temperature and low humidity environments cause frost due to moisture in the air, which causes corrosion of mechanical structures and failure of electronic devices. To prevent this, operating structures (machinery, electromagnetic operating devices) must be excluded from high humidity and low temperature environments. In addition, the automatically operated transfer device transfers the object using power. However, if the object to be transported is inoperable due to unnecessary interference, the transport device operates without detecting this, which may lead to damage to the object to be moved and damage to the power unit.

In order to solve this problem, the present invention makes it possible to prevent damage to the moving object and the power device by separating the moving conveyor from the moving device even when the power of the moving device is activated when there is an interference load greater than a certain conveying force.

The present invention (Examples 1-1 to 1-5) relates to a transfer device. Inside the main body, an internal conveyor that moves linearly with an actuator is installed, and an external conveyor is formed outside the main body. The internal transporter and the external transporter have magnetic attraction and propulsion force. (The technical details of magnetic transfer are described later.)

Since the main body is a sealed structure, it is not affected by frost in a high humidity and low temperature environment. Therefore, due to the sealed structure of the main body, the conveying force is realized by magnetic force.

The external transport body is attached to the internal transport body of the main body by magnetic force and generates transport force according to the movement of the internal transport body. In other words, if a load greater than the magnetic force is applied, the external carrier is easily separated from the main body. This enables easy replacement of the external carrier.

If the sealing conditions of the main body are damaged, moisture in a high-humidity environment may penetrate into the main body and damage the actuator and electronic devices of the main body. To prevent this, a temperature and humidity sensor is installed inside the main body, and the temperature device is driven by a temperature controller to prevent moisture from being generated inside the main body. It is preferable to use a Teltier element as the temperature device, and a heating heater can be used as needed.

[Example 2-1] The present invention relates to a transfer device, and in Example 1-1, it includes a transfer guide 500 formed on one surface of the main body and with which the internal transfer body and the external transfer body come into contact. do.

[Example 2-2] The present invention relates to a transfer device, and in Example 1-1, the transfer guide is a part of the main body and is integrated with the main body.

[Example 2-3] The present invention relates to a transfer device, and in Example 1-1, the transfer guide is formed of a non-magnetic material.

[Example 2-4] The present invention relates to a transfer device, and in Example 1-1, a guide groove 510 formed in the transfer guide; or a guide protrusion 520.

[Example 2-5] The present invention relates to a transfer device, and in Example 1-1, it includes a transfer wheel 420 that is coupled to the external transfer body and rotates in contact with the transfer guide.

[Example 2-6] The present invention relates to a transfer device, and in Example 1-1, a first inclined surface 421 formed at a corner of the transfer wheel; It is formed on the transfer guide and includes a second inclined surface 511 formed opposite to the first inclined surface.

[Example 2-7] The present invention relates to a transfer device, and in Example 1-1, the transfer guide is made of polymer.

[Example 2-8] The present invention relates to a transfer device, and in Example 1-1, the polymer is formed of nylon or Teflon material.

The present invention (Examples 2-1 to 2-8) embodies a transfer guide.

The transfer guide is formed on one side of the main body. The transfer guide increases the transfer effect of internal and external transfer elements and improves the accuracy of transfer direction. Since the main body is a sealed structure, one side of the main body separates the internal and external conveyors by a certain length, which causes a decrease in magnetic force. However, if one side of the main body is formed as a transfer guide, high magnetic force can be maintained. In addition, the transport direction accuracy of the internal transport body and the external transport body can be improved by the transport guide.

The guide is made of a non-magnetic material, which makes it possible to maintain the magnetic force of the internal transport material and the external magnetic material. The transfer guide can be attached to one side of the main body, but the main body and transfer guide can be formed as one piece.

The transport guide forms grooves or protrusions on the surface, and the external transporter and internal transporter have structures corresponding to the grooves or protrusions, so they can be maintained in a fitted state. This improves the accuracy of transfer direction.

The external transport body and the internal transport body can be equipped with a transport wheel. Rotation of the transfer wheel can effectively maintain the transfer force. The edge of the transfer wheel forms an inclined surface, and the transfer guide also forms an inclined surface corresponding to the inclined surface. This leads to a stable direction.

The external and internal transport elements take the form of blocks and can be transported through sliding contact with the transport guide.

In order to reduce the friction coefficient of the contact surface between the transfer guide and the transfer body, the transfer guide is preferably made of Teflon material. In addition, the edges of the internal and external transport bodies are rounded or chamfered to enable smooth transport.

[Example 3-1] The present invention relates to a transfer device. In Example 1-1, the actuator 300 includes a reciprocating movement means 310 that reciprocates inside the main body; It includes an electric motor 330 that supplies rotational force to the reciprocating moving means.

[Example 3-2] The present invention relates to a transfer device. In Example 3-1, the reciprocating transfer means includes a driving pulley 311 axially coupled to the electric motor; a driven pulley (312) installed to be spaced apart from the driving pulley; It includes a belt 313 that is mounted on the driving pulley and the driven pulley and to which the first magnetic force transporter is attached.

[Example 3-3] The present invention relates to a transfer device, and in Example 3-1, the belt includes a timing belt (313a) or a flat belt (313b).

[Example 3-4] The present invention relates to a transfer device, and in Example 3-1, it includes a tension maintaining device 320 that is coupled to the belt and maintains the tension of the belt constant.

[Example 3-5] The present invention relates to a transfer device, and in Example 3-4, the tension maintaining device includes a tension maintaining magnetic 321 fastened to the belt; It is located on the inner wall of the main body and includes a metal plate 322 made of metal.

[Example 3-6] The present invention relates to a transfer device. In Example 3-1, the reciprocating transfer means has a shaft shape and includes a main rotation shaft 314 that rotates in combination with the electric motor; It is coupled to the main rotation shaft, moves linearly as the main rotation shaft rotates, and includes a transfer block 316 to which the internal transfer body is coupled.

[Example 3-7] The present invention relates to a transfer device, and in Example 3-6, the main rotation axis and the transfer block are formed of a ball screw.

The present invention (Examples 3-1 to 3-7) embodies an actuator.

The actuator is located inside the main body, and forms a reciprocating moving means that is transported in the longitudinal direction of the main body inside the main body, and the reciprocating moving means is operated by the actuator. The actuator is an electric motor, but a pneumatic motor can be used as needed. The electric motor uses a stepping motor to accurately drive the rotation angle.

As an embodiment of the reciprocating transport means, a driving pulley and a driven pulley are disposed at both ends of the main body, and an electric motor is mounted on the driving pulley. The driving pulley and the driven pulley are fastened with a belt, and an internal conveyor is mounted on the belt. In other words, the rotation of the electric motor implements horizontal movement of the internal carrier.

As another embodiment of the reciprocating transfer means, the drive motor is coupled to the main rotation shaft, and a transfer block whose rotation is restricted is coupled to the main rotation shaft. The outer periphery of the main rotation shaft forms a bolt shape, and the transfer block forms a nut coupled to the bolt. Therefore, rotation of the main rotation axis enables horizontal movement of the transfer block. As another embodiment of the reciprocating transfer means, the main rotation axis and transfer block may have a ball screw structure.

A flat belt or timing belt can be used as the belt, but it is preferable to use a timing belt. Alternatively, wire can be used in place of the belt.

The belt may be stretched by long-term use and is affected by vibration due to actuator operation. To solve this problem, the belt is equipped with a tension maintaining device. The tension maintaining device fixes a tension maintaining magnet to the belt, and attaches a metal plate formed in the longitudinal direction inside the main body. In other words, the tension-maintaining magnet generates magnetic force with the metal plate, which can exert the effect of maintaining tension.

[Example 4-1] The present invention relates to a transfer device, and in Example 1-1, it includes a transfer frame 600 that is coupled to the external transfer body and is in contact with the transfer object (P). .

[Example 4-2] The present invention relates to a transfer device, and in Example 4-1, a coupling means 610 is formed on one surface of the transfer frame and is selectively coupled to the external transfer body; Includes.

[Example 4-3] The present invention relates to a transfer device, and in Example 4-1, it includes a transfer roller 621 formed on the transfer frame and in contact with the transfer object.

[Example 4-4] The present invention relates to a transfer device, and in Example 4-1, the roller is formed as one or more.

[Example 4-5] The present invention relates to a transfer device, and in Example 4-1, it includes a contact plate 622 formed on the transfer frame and in contact with the transfer object.

[Example 4-6] The present invention relates to a transfer device, and in Example 4-1, the contact plate is formed of polymer.

[Example 4-7] The present invention relates to a transfer device, and in Example 4-1, the polymer is made of nylon material or Teflon material.

The present invention (Examples 4-1 to 4-7) embodies a transfer frame.

The transport frame is combined with an external transport body and is in close contact with the main body. In other words, it is transported together with an external carrier. On the other hand, since it comes into contact with the transfer object listed outside the main body, the transfer object is transferred.

The transport frame and the external transport body are coupled by a coupling means. The reason for using a coupling means is to implement selective attachment and detachment. The coupling means may be coupled with a plurality of pins, fastened with bolts, or fastened with a groove and protrusion coupling structure.

If the transfer object receives unnecessary external interference, the transfer frame is not transferred along the internal transfer body and is separated from the main body. Therefore, damage to the transported object can be prevented.

In order to increase the transfer effect, one side of the transfer frame is equipped with a roller. That is, the transfer object can be brought into contact with the roller and transferred by roller rotation. The transport roller may be formed as one or more.

One side of the transfer frame may be equipped with a Teflon contact plate or a rubber plate.

The contact plate and rubber plate are in contact with the transfer object, and can be selectively used according to the shape characteristics and transport characteristics of the transfer object.

[Example 5-1] The present invention relates to a transfer device, and in Example 1-1, it includes a stopper 700 formed on the main body and selectively interfering with the discharge of the transfer object (P). .

[Example 5-2] The present invention relates to a transfer device. In Example 5-1, the stopper includes a boss 711 coupled to the main body; An arm 712 protruding from the boss; It is coupled to the boss and includes a stopper shaft 713 coupled to the main body.

[Example 5-3] The present invention relates to a transfer device, and in Example 5-2, it includes a rotation angle control means 720 formed on the stopper shaft and controlling the rotation angle.

[Example 5-4] The present invention relates to a transfer device. In Example 5-1, the rotation angle control means includes an internal boss 721 coupled to a stopper shaft; A spring groove 722 formed on the inner boss, formed in plural, and formed at a set angle; It includes a spring 723, one side of which is coupled to the boss, and the other side of which is coupled to the spring groove.

[Example 5-5] The present invention relates to a transfer device, and in Example 5-1, the rotation angle control means includes a power transmission means 724 whose power is interlocked with the actuator.

The present invention (Examples 5-1 to 5-5) embodies a stopper.

The stopper selectively interferes with the discharge of the transported object, which enables accurate discharge quantity control. The stopper detects the status of the transfer frame and operates in conjunction with it. This can have the effect of selectively classifying emission targets.

To implement this, a boss fixed to the stopper shaft is formed in the center of the stopper, and a plurality of arms are installed in the outer circumferential direction of the repair. The plurality of arms are arranged at even intervals. The plurality of arms can be replaced according to the external shape of the transfer object. This is achieved by selectively attaching and detaching the boss and stopper shaft.

The stopper axis operates in segments at a set angle. To implement this, an internal boss is mounted on the stopper shaft, and grooves are formed at divided angles on the outer periphery of the internal boss. The groove inserts a protrusion coupled with a spring, and the rotation of the stopper shaft is temporarily restricted in the groove. If the elastic force of the spring is exceeded by an external force, the effect of rotating the stopper shaft again can be obtained.

In another embodiment, the stopper is linked to the actuator as a power transmission means. The power transmission means may be implemented as a gear combination.

[Example 6-1] The present invention relates to a transfer device, and in Example 1-1, a first magnetic 210 attached to the internal transfer body 200; It includes a second magnetic 410 attached to the external carrier 400.

[Example 6-2] The present invention relates to a transfer device, and in Example 6-1, the first and second magnetics are arranged in plural numbers.

[Example 6-3] The present invention relates to a transfer device, and in Example 6-2, the plurality of items is arranged in the row direction of the transfer direction.

[Example 6-4] The present invention relates to a transfer device, and in Example 6-2, the plurality of units is arranged in the column direction of the transfer direction.

[Example 6-5] The present invention relates to a transfer device, and in Example 6-2, the first and second magnets disposed opposite each other are formed with different poles.

The present invention (Examples 6-1 to 6-5) specifies the combination relationship between the internal transporter and the external transporter. The external transporter can transmit manpower and transport force through magnetic force to the internal transporter. The reason for using magnetic force is to distinguish between the sealed space of the main body and the transfer space where the transfer object is located.

When the external transport body is inoperable due to unnecessary interference, the external transport body is separated from the main body, which prevents damage to the transported object and the actuator.

The internal transporter is equipped with a first magnet, and the external transporter is equipped with a second magnet. The first and second magnets are located facing the wall of the main body.

The first magnet and the second magnet are detachable from the internal transporter and the external transporter. In other words, the purpose of replacing the first and second magnetic poles is to control magnetic force. The first and second magnets may be arranged in plural numbers. The arrangement can be arranged row-wise and/or longitudinally.

[Example 7-1] The present invention relates to a transfer device, and in Example 1-1, a first position sensor 131 is located outside the main body and detects the position of the external transfer body; It includes an operation controller 132 that recognizes the signal from the first position sensor and controls the operation of the actuator.

[Example 7-2] The present invention relates to a transfer device. In Example 7-1, an object detection sensor 133 is located outside the main body and detects the presence of a transfer object (P); Includes.

[Example 7-3] The present invention relates to a transfer device, and in Example 7-1, a torque meter 341 coupled to the actuator; It includes a torque controller 343 that senses the signal from the torque meter and controls the operation of the actuator.

[Example 7-4] The present invention relates to a transfer device, and in Example 7-1, a current detection sensor 342 that detects the power current of the actuator; It includes a current controller 344 that detects the current sensor signal and controls the operation of the actuator.

[Example 7-5] The present invention relates to a transfer device, and in Examples 7-3 and 7-4, the torque controller and the current controller are formed integrally with the operation controller.

The purpose of the present invention (Examples 7-1 to 7-5) is to control the operating state of the transfer device.

The external transporter must exist in the same location as the internal transporter. Alternatively, if the external transporter and the internal transporter are separated by magnetic force, the external transporter can move in the reverse direction and re-operate by attaching the internal transporter again using magnetic force.

To implement this, a first position sensor to detect the position of the external carrier must be formed on the surface of the main body. Accordingly, the location of the external carrier can be confirmed in real time using the first position detection sensor. This is implemented as an operation controller.

Additionally, an object detection sensor is mounted on the main body, and the quantity and location of transported objects can be confirmed. The signal from the object detection sensor is detected by the operation controller presented above, and the operation controller can position the external carrier at the position of the operating object by moving the internal carrier in the forward and reverse directions.

In order to detect if the transfer object cannot be transferred due to unnecessary interference, any abnormality is detected by a torque meter or power detection sensor mounted on the actuator. If an abnormality is detected, the forward and reverse transfer of the internal transfer object is performed. It can work by performing it repeatedly.
