Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are provided to fully convey the spirit of the present invention to a person having ordinary skill in the art to which the present invention belongs. The present invention is not limited to the embodiments shown herein but may be embodied in other forms. For the sake of clarity, the drawings are not drawn to scale, and the size of the elements may be slightly exaggerated to facilitate understanding.

1 is a view showing a transfer device 10 for a ring member according to an embodiment of the present invention.

1, a transfer device 10 for a ring member according to an embodiment of the present invention includes a material input unit 100, a pre-operation transfer unit 200, a material operation unit 300, a post-operation transfer unit 400, and a material storage unit 500.

Fig. 2 is a view showing the material input unit 100. Fig.

The material input unit 100 can execute a procedure in which a plurality of materials are aligned and arranged so as to be sequentially conveyed to a place where the materials are put into a waiting state before being conveyed.

Here, the material may be a ring member. The ring member may have a circular ring shape. The ring member may be provided so as to have a step in the axial direction. For example, the inner diameter may be the same, and the outer diameter may be formed to have the first outer diameter and the second outer diameter.

The material may be seated on the material input unit 100 so that one side faces downward. For example, the second outer diameter can be seated on the material input portion 100 so as to face the bottom.

2, the material input unit 100 may include an atmospheric region 110 where a plurality of materials are waiting, and an entry path 120 connecting the atmospheric region 110 and the material transfer unit.

The waiting area 110 may have a large area so that a plurality of materials can be arranged in a first direction as well as a second direction perpendicular to the first direction. Here, the first direction means a direction parallel to the direction in which the material moves through the entry path 120. A plurality of materials can be stored in the waiting area 110 and wait for work. Accordingly, it is possible to store a large amount of materials in advance in the waiting area 110 without increasing the supply speed of the materials according to the operation speed, thereby increasing the efficiency of the work.

One side of the waiting area 110 may be provided in a straight line. One side of the atmospheric region 110 provided in a straight line may be connected by the same straight line as one side of the entrance passage 120. The material positioned adjacent to one side of the atmospheric region 110 can be guided to one side of the atmospheric region 110 and enter the entry path 120. [

The front surface (entrance direction side surface) of the atmospheric region 110 may be provided as an inclined surface inclined toward the entrance passage 120. Therefore, the materials positioned on the front side of the waiting area 110 can be guided to the entry path 120 along the slope. The inclination angle of the front surface may be an angle between 40 degrees and 50 degrees. Preferably, the inclination angle of the front surface may be 45 degrees. If the inclination angle of the front face is set to be less than 45 degrees, the force of guiding the materials toward the entry passage 120 may become weaker than the reference size. In this case, the materials located far away from the entry path 120 may not enter the entry path 120 and may stagnate at the same place. On the other hand, if the angle of inclination of the front surface is set to be faster than 45 degrees, the force of guiding the materials toward the entrance path 120 becomes larger than necessary, and congestion phenomenon may occur where the materials can not move together.

In addition, the waiting area 110 may include a seating portion on which the materials are seated.

The seat portion may include a movable seat portion 111 and a rearrangement seat portion 112. The mobile seating part 111 and the re-alignment seating part 112 may be located adjacent to each other. The mobile seating part 111 and the rearrangement seating part 112 are relatively movable. For example, the mobile seating part 111 may be configured to move continuously in the first direction, and the rearrangement seating part 112 may be configured to move in the first direction and reciprocate within a predetermined interval.

The movable seating part 111 may include a conveyor belt connecting the waiting area 110 and the entry passage 120. The movable seating part 111 has a length that one side covers one side opposite to the entry passage 120 of the waiting area 110 and the other side covers one side in the advancing direction of the entry passage 120 . Roller (not shown) may be provided on both sides of the movable seating part 111. The moving seat part 111 may be arranged to move in the direction of the entry passage 120 while moving in the endless track.

The rearrangement seating part 112 may be provided to cover the remaining area except the area where the moving seating part 111 is provided in the waiting area 110. [ And rollers (not shown) may be provided on both sides of the re- The re-alignment seating portion 112 can be provided to be reciprocally movable in both directions. The rearrangement seating portion 112 guides the materials to the entry passage 120 while moving in the entry direction. And the rearrangement seating portion 112 can move in the direction opposite to the entering direction, thereby relieving the stagnation of the materials. A bottleneck may occur in the vicinity of the entry passage 120 while the materials move in the entry direction. The bottleneck phenomenon refers to a phenomenon that congestion occurs due to narrowing in the direction of travel. There is a mutual interference between the materials densely located in the vicinity of the entry passage 120, so that the materials can not enter the entry passage 120 despite the moving direction of the movement seating part 111. At this time, the rearrangement seating portion 112 moves in the direction opposite to the entering direction, and the materials in the vicinity of the entrance passage 120 can be partially moved in the direction opposite to the entering direction. In this process, bottlenecks between materials can be mitigated.

The material input unit 100 may include an entry passage 120 to which only one material can enter. The materials may enter side by side through entry path 120. And the width of the entry passage 120 (the distance between both side walls of the entry passage 120) may be greater than the diameter of the material and less than three times the radius of the material. When the width of the entry passage 120 is provided in a manner similar to the diameter of the material, the engagement may be caused by friction. In addition, when the width of the entry passage 120 is set to be larger than three times the radius of the material, adjacent materials may be caught in the width direction. This is because the magnitude of the force component acting between the adjacent materials is larger than that of the material in the transverse direction. That is, since the width of the entry passage 120 is larger than the diameter of the material and is not more than three times the radius of the material, the material can be guided to pass through the entrance passage 120 without being stagnated.

It has been described above that one side of the entry passage 120 is provided in a straight line with the waiting area 110 and the side surface. The other side of the entry passage 120 is connected to the front side of the waiting area 110, but may be curved. Specifically, the front surface of the atmospheric region 110 is formed as an inclined surface, and the front surface and the other surface of the entrance passage 120 may be curved. The curved surface may be provided to have a positive curvature. In other words, the surface can be convex. One side of the curved surface can be differentially connected to the front surface of the atmosphere area 110 and the other side of the curved surface can be differentially connected to the other side of the entrance path 120. [ It is possible to prevent the material from being caught by removing the non-differentiable point.

The entry passage 120 may be provided in the first direction. The first opening 121 provided at the inlet side of the entry passage 120 may communicate with the atmospheric region 110 to receive the material. And the second opening 122 provided at the outlet side of the entry passage 120 can communicate with the material conveying portion to convey the material.

The first opening 121 of the entry passage 120 may be parallel to the first direction. However, the second opening 122 of the entry passage 120 may be provided in a direction which is deviated from the first direction. For example, the exit side of the entry passage 120 may be connected at an angle of 90 degrees with the material transfer section.

In addition, the entry passage 120 may include a first stationary stopper 123 positioned parallel to an end of the second opening 122. [ The first stationary stopper 123 prevents the material moving in the first direction through the entry path 120 from moving further. Beyond the first stationary stopper 123, a roller (not shown) for driving the movable seating part 111 can be located.

The entry passage 120 is located in the forward direction of the first fixed starter 123 and moves the first stopper 123 to the first feeder 124 (Pusher). The first pusher 124 may include a cylinder positioned opposite the second opening 122 and advancing towards the second opening 122.

The entry passage 120 is also located behind the first pusher 124 and prevents any further material from approaching the vicinity of the first pusher 124 so that the first pusher 124 can push only one piece of material And may include a first variable starter. The first variable starter may be operable to protrude from one side of the entry passage 120. The first variable starter operates to protrude to prevent movement of the material in the first direction and to operate in the opposite direction to permit movement of the material in the first direction. Due to the movement of the first variable starter, the materials can be moved to the first fixed starter 123 one by one and moved to the material transporting part by the first pusher 124 one by one. One side (a direction adjacent to the material) of the first variable starter may be provided in a wedge shape, or a surface in contact with the material may be provided in an inclined or convex curved surface.

The first variable starter may include a first primary variable starter and a second primary variable starter disposed in parallel in the direction of travel. The material moves from the first primary variable starter to the second primary variable starter. One material can be positioned between the primary first variable starter positioned forward in the direction of travel and the secondary first variable starter located in the rearward direction. And the primary first variable starter and the secondary first variable starter can operate relatively. For example, the first primary variable starter may not protrude when the secondary first variable starter is protruding and blocking materials. At the moment the second primary variable starter is released, the first primary variable starter operates to block the materials. In this process, only one material moves in the direction of the first fixed starter 123.

Alternatively, both the primary first variable starter and the secondary first variable starter may operate to block the materials. That is, the first primary variable starter may block the material located in the forward direction, and the secondary first variable starter may be blocking the material located in the next forward direction (rearward). At this time, after the secondary first variable starter is opened and one material is moved in the direction of the first fixed starter 123, the secondary first variable starter is directly operated and converted into a state in which the material can be blocked. Then, after the first primary variable starter is opened and one material is moved toward the secondary first variable starter, the first primary variable starter immediately operates and is converted into a state capable of blocking the material. And when the first primary variable starter and the second primary variable starter operate at the same time, the transportation time of the material can be reduced.

In addition, the entry passage 120 may include a sensor positioned behind (in the advancing direction) of the secondary first variable starter. The sensor may sense whether the material is traveling through the secondary first variable starter and toward the first stationary stop 123. If the sensor recognizes that there is no material passing through the secondary first variable starter, the primary first variable starter opens and moves the material toward the secondary first variable starter. At this time, the secondary first variable starter protrudes and is blocking the material.

Next, the first modification and the second modification of the material input unit 100 will be described.

In the first modified embodiment of the material input unit 100, the seating portion may be inclined so as to have a difference in height in the first direction. The seat portion is inclined in the first direction so that the materials away from the entry passage 120 are moved toward the entry passage 120 by the potential energy.

In the second modified embodiment of the material input unit 100, the re-alignment seating unit 112 may be inclined so as to have a difference in height in the second direction. The rearrangement seating portion 112 is inclined in the second direction so that the materials away from the moving seating portion 111 are moved toward the moving seating portion 111 by the potential energy.

In addition, the mobile seating part 111 and the rearrangement seating part 112 may be provided at different slopes. For example, the mobile seating part 111 may be provided in a plane or be inclined in the first direction, and the rearrangement seating part 112 may be inclined in the second direction.

In addition, the re-alignment seating portion 112 may be inclined in both the first direction and the second direction. The rearrangement seating portion 112 is inclined in the first and second directions so that the materials separated from the moving seating portion 111 are moved toward the entrance passage 120 by the potential energy.

On the other hand, the inclination of the moving seat 111 and the rearrangement seat 112 can be adjusted. For example, one side of the mobile seating part 111 and one side of the rearrangement seating part 112 may be made different in height by a cylinder or the like.

The inclination of the mobile seating part 111 and / or the re-alignment seating part 112 can be adjusted differently depending on the conveying speed of the material and / or the weight of the material. For example, as the conveying speed and / or the weight of the material increases, the inclination of the moving seat 111 and / or the rearrangement seat 112 may be increased.

Next, the third modified embodiment and the fourth modified embodiment of the material input unit 100 will be described.

In the third modified embodiment of the material input unit 100, the front face of the re-alignment seating unit 112 may include a plurality of conveying rollers.

Some of the plurality of conveying rollers may be provided as drive rollers. The driving conveying roller can move the material in the direction of the entry passage 120. [

In the fourth modified embodiment of the material input unit 100, the front surface of the rearrangement receiving portion 112 is provided so as to have a different angle of inclination. The front face may include a moving bar. The movement bar may be provided to rotate about a rotation axis located at one side adjacent to the entry passage 120. The rotary shaft is connected to a motor (not shown) and can rotate. The inclination angle of the front face of the re-alignment seating part 112 can be changed while the movable bar is rotated by driving the motor.

The rearrangement seating portion 112 can reduce the inclination angle of the front surface, thereby alleviating the stagnation phenomenon of the material. The rotating shaft rotates in one direction to increase the tilt angle of the front surface, and the moving bar pushes the material in the second direction. In this process, the materials move in the direction of the moving seat part 111 and re-arrangement occurs due to the mutual forces generated between the materials.

Then, the rotation axis rotates in the opposite direction, and the inclination angle of the front surface decreases, so that the movement bar retreats from the materials. In this process, the mutual forces that occur between the materials are released, which can alleviate the phenomenon of pinching.

Although not shown in the drawing, the material input unit 100 according to the embodiment of the present invention includes a sensor or a camera that can detect whether materials are stagnant due to a bottleneck phenomenon in the vicinity of the entry path 120, And a control unit for receiving the information and generating an operation signal to the driving unit.

If it is determined that congestion is generated from the information received from the sensor or the camera, the control unit moves the re-alignment seating unit 112 in the direction opposite to the traveling direction or alleviates the inclination of the moving and / or rearranging seating unit 112 Or the angle of the moving bar can be relaxed.

Next, the material conveyance unit and the material operation unit 300 will be described with reference to FIG. 3 to FIG.

FIG. 3 is a view showing the pre-work conveying unit 200 and the material work unit 300, and FIG. 4 is a view sequentially showing the work of the material work unit 300. As shown in FIG.

The material transfer unit includes a pre-work transfer unit 200 connected at one end to the entry path 120 and connected to a plurality of the material work units 300 during the material transfer path, And a work post-transfer unit 400 for transferring completed materials to the material work unit 300 and sequentially transferring the completed materials to the material storage unit 500. FIG.

The pre-work feeder 200 is connected to the entry passage 120 and includes a passage through which the material pushed by the first pusher 124 moves. The pre-work transfer unit 200 may be connected to the work unit 300 to move the work to the work unit 300. The pre-work transfer unit 200 may be connected to a plurality of material work units 300. For example, the pre-operation transfer unit 200 is sequentially connected to the first to third work units 300, and the materials are selectively moved to one of the first to third work units 300, The UPH (Unit per Hour) of the mobile terminal can be improved.

A roller (not shown) may be provided on both sides of the transfer unit 200 before the operation. The seat part on which the material is seated can be arranged to move in an infinite orbit, and to move in a traveling direction of the transfer part 200 before the operation.

The pre-operation transfer unit 200 may extend in the second direction. The third opening 210 provided at the inlet side of the pre-operation transfer unit 200 can communicate with the entrance passage 120 to receive the material. The third opening 210 may be parallel to the second direction.

The pre-work feeder 200 may also include a respective work part transfer starter 220 for pausing the material moving along the seating part to move to each material work part 300.

And the work part transfer starter 220 may be drivably provided. The work part transfer starter 220 may protrude from the driven state toward the seat part to prevent the movement of the material and allow the movement of the material away from the seat part in the disengaged state. For example, the work station transfer star 220 may be arranged to move up and down. The work part transfer starter 220 can be moved downward to block the passage of the transfer part 200 before the work and can move up to open the passage of the transfer part 200 before the operation.

The work part transfer starter 220 may be provided in plural or may be provided to correspond to a plurality of the material work units 300. And the plurality of work station transfer needles 220 are relatively drivable. The other work part transfer starter 220 can release the operation while any one work part transfer starter 220 is projected to block the material.

And the last working part transfer star 220 may not be driven. A roller (not shown) may be disposed beyond the last working transfer starter 220. Thus, the last working part transfer star 220 is always kept in a state to prevent movement of the material.

The transfer unit 200 before the work is moved to the material work unit 300 while the work station transfer stopper 220 is positioned in the forward direction And a pusher 230 (pusher). The workpiece delivery pusher 230 may include a cylinder that advances toward the workpiece 300. For example, the work part transfer pusher 230 may be located at one side of the seat part and may push out the material that has been stopped by the work part transfer stirrup while being stretched. When the material separates from the seat part, the work part transfer pusher 230 can return to its original state.

In addition, the pre-work transfer unit 200 may further include a plurality of second variable stabbers 240 and a plurality of sensors respectively positioned in front of the plurality of work units 300.

The second variable starter 240 may be operable to protrude from one side of the material transfer part. The second adjustable stopper 240 operates to protrude to prevent movement of the material in the second direction and to operate in the opposite direction to permit movement of the material in the second direction. By the movement of the second variable stopper 240, the materials can move in the advancing direction one by one. One side (direction adjacent to the material) of the second variable starter 240 may be provided in a wedge shape, or a surface in contact with the material may be provided in an inclined or convex curved surface.

The second variable starter 240 may include a first-order second variable starter 240 and a second-order second variable starter 240 disposed in parallel to each other in the traveling direction. The material moves to the second secondary variable starter 240 through the first secondary variable starter 240. One material may be positioned between the primary second variable starter 240 located in front of the traveling direction and the secondary secondary variable starter 240 located at the rear. And the primary second variable starter 240 and the secondary secondary variable starter 240 can operate relatively. For example, the primary second variable starter 240 may not protrude when the secondary secondary variable starter 240 protrudes and blocks materials. At the moment when the second secondary variable starter 240 is released, the primary second variable starter 240 operates to block the materials. In this process, only one material moves in the direction of the second fixed starter 420.

Or both the primary second variable starter 240 and the secondary second variable starter 240 may operate to block the materials. In other words, the primary second variable starter 240 may block the material positioned in front, and the secondary second variable starter 240 may be in a state blocking the material positioned in the immediately following direction (rearward) . At this time, the secondary second variable starter 240 is opened to move one material in the direction of the second fixed starter 420, and then the secondary second variable starter 240 operates to block the material And is converted into a state in which it is possible. Then, after the first secondary variable starter 240 is opened and one material is moved toward the secondary secondary variable star 240, the primary secondary variable starter 240 immediately operates to block the material And is converted into a state in which it is possible. When the operation of the first secondary variable starter 240 and the operation of the secondary second variable starter 240 are simultaneously performed, the transporting time of the material can be reduced.

In addition, the pre-operation transfer unit 200 may include a sensor positioned in the back (forward direction) of the secondary second variable starter 240. The sensor may sense whether the material is traveling through the secondary second variable starter 240 and toward the second stationary starter 420. If the sensor recognizes that there is no material passing through the secondary second variable starter 240, the primary secondary variable starter 240 is opened and the material is directed in the direction of the secondary secondary variable star 240 . At this time, the secondary second variable starter 240 protrudes to block the material.

Next, a description will be given of a case where materials moved to the material work unit 300 from the pre-work transfer unit 200 are worked.

FIG. 5 is a view showing the rotation of the pick-up unit 320, and FIG. 6 is a view showing a state in which the pick-up unit 320 delivers the material to the post-workpiece transferring unit 400.

The material work portion 300 includes an intermediate transfer unit 310 facing the work portion transfer pusher 230 and located opposite the seating portion of the pre-work transfer portion 200. The intermediate transfer unit 310 may be provided with a pick-up place where the moving material is seated by the operation of the work part transfer pusher 230. And the intermediate transfer unit 310 may include a pick-up fixing starter provided at one side of the pick-up place so as to fix the material to a predetermined position. The work material pusher 230 pushes the material to the pick-up place and is located at a place determined by the pick-up stationary stopper at the pick-up place.

The intermediate transfer unit 310 may be provided so as to be movable up and down. For example, the intermediate transfer unit 310 can move up and down by the operation of the cylinder. The intermediate transfer unit 310 can be raised when the material is positioned at a predetermined place of the pick-up place.

The pick-up unit 320 can pick up the material when the intermediate transfer unit 310 rises and moves the material up.

The pick-up unit 320 may include a fixed body, a rotating body rotatably provided on one side of the fixed body, a first pick-up member and a second pick-up member connected to the rotating body, have.

The rotary shaft of the rotary body may be disposed at an angle of 45 degrees in the vertical direction. And the longitudinal direction of the first pick-up member and the longitudinal direction of the second pick-up member may be disposed at an angle of 45 degrees with the rotational axis, respectively.

The rotating body may be rotated by 180 degrees to shift the position of the first pick-up member and the position of the second pick-up member. For example, when the first pick-up member faces downward and the second pick-up member is positioned in the horizontal direction with respect to the ground, when the rotary body rotates 180 degrees, the first pick-up member is positioned in the horizontal direction with respect to the ground, .

The rotating body may be rotated 180 degrees clockwise and then rotated 180 degrees clockwise. Alternatively, the rotating body may be rotated 180 degrees in the clockwise direction and then rotated 180 degrees in the counterclockwise direction.

And the first pick-up member and the second pick-up member may include a grip portion. The grip part can hold the material or place the material by repeating the action of being worn and widened. For example, the grip portion may include three grip members arranged at intervals of 120 degrees, and the grip member may be provided to reciprocate in the radial direction. The grip members can move at the same time. The gripping members can move in the center direction while holding the material, and the gripping members can move the material in the opposite direction.

The first pick-up member can pick up the material from the raised intermediate transfer unit 310. Then, the rotating body rotates 180 degrees so that the first pick-up member is positioned horizontally with the ground and the second pick-up member faces downward. And the intermediate transfer unit 310 can be moved down to receive the new material. And the second pick-up member can pick up the material from the intermediate transfer unit 310 which has risen again. Accordingly, the first pick-up member and the second pick-up member pick up the material of the rotating body, respectively, so that the two bodies can be sequentially worked, and the working speed can be improved.

Meanwhile, although not shown in the figure, four pick-up members can be connected to the rotating body. In this case, each pick-up member can pick up the material while the rotating body rotates by 90 degrees.

The fixed body may be provided to move forward and backward in the horizontal direction with respect to the ground. For example, the fixed body may include a driving wheel moving on a rail provided in a horizontal direction. When the drive wheel rotates in one direction, the fixed body advances, and when the drive wheel rotates in the opposite direction, the fixed body can be reversed. Or the fixed body may be connected to the cylinder to move forward and backward.

The working unit 330 can be positioned in front of the fixed body. For example, the work unit 330 may include a polishing pad.

The fixed body may advance and deliver the material picked up to the first or second pick-up member to the work unit 330. [ When the fixed body advances and the material picked up on the first pick-up member contacts the work unit 330, the grip members can deliver the material to the work unit 330 by releasing the material. Then, the work unit 330 can start work after the fixed body is moved backward.

Then, the fixed body is advanced again to receive the finished work from the work unit 330 to the first or second pick-up member. When the fixed body advances and the first pick-up member contacts the material, the grip members can receive the material from the work unit 330 by holding the material. Then, the rotating body can be rotated by 180 degrees in a state in which the fixed body is retracted and interference with the operation unit 330 is released.

And the fixed body may advance to transfer the material picked up to the second pick-up member to the work unit 330. [

By repeating this series of processes, the materials are transferred from the pick-up unit 320 to the work unit 330 to perform work, and the finished work can be transferred from the work unit 330 to the pick-up unit 320. Further, productivity of the work can be improved by picking up all the materials of the plurality of pick-up members.

On the other hand, an opening / closing door may be provided in front of the operation unit 330. The opening and closing door may be closed during the operation of the operation unit 330 and may be opened after the operation of the operation unit 330 is completed. The fixed body may advance in a state in which the opening / closing door is opened to transfer the material to the operation unit 330.

The fourth opening 410 provided on the outlet side of the post-work conveying unit 400 may communicate with the material storage unit 500 to transfer the material. The fourth opening 410 may be provided in a direction deviating from the second direction. For example, the outlet side of the work post-processing unit 400 may be connected to the material storage unit 500 at an angle of 90 degrees.

After the work, the transfer part 400 may include a second fixing starter 420 positioned parallel to one side of the fourth opening 410. The second stationary stopper 420 prevents the material moving in the second direction through the post-worker conveying unit 400 from moving further. A roller (not shown) for driving the post portion of the post-work station 400 may be located beyond the second stationary stopper 420.

The post-work feeder 400 moves the material stopped by the second fixed starter 420 to the material storage unit 500 in the forward (direction opposite to the direction of travel) of the second fixed starter 420 And a second pusher 430 (pusher). The second pusher 430 may include a cylinder positioned facing the fourth opening 410 and advancing toward the fourth opening 410.

The second pusher 430 may be provided in a bar shape to push out a plurality of materials. A plurality of materials can be transferred to the material storage unit 500 by advancing the second pusher 430 once.

The post-operation transfer unit 400 is located behind the second pusher 430 and moves to the vicinity of the second pusher 430 so that the second pusher 430 can push out only the positive material And a third variable starter that prevents it from < / RTI > The third variable starter may be operable to protrude from one side of the transfer part 400 after the operation. The third variable starter operates to protrude to prevent movement of the material in the second direction and to move in the opposite direction to permit movement of the material in the second direction. By the movement of the third variable starter, the materials can be moved to the second fixed starter 420 one by one and moved to the material storage 500 by the second pusher 430 within the allowed number. One side (direction adjacent to the material) of the third variable starter may be provided in a wedge shape, or a surface in contact with the material may be provided in an inclined or convex curved surface.

After the work, the transfer unit 400 may be disposed in parallel with the transfer unit 200 before the operation. For example, post-work transfer unit 400 may be located between pre-work transfer unit 200 and work unit 330. The pick-up unit 320 transfers the completed work from the work unit 330 to the post-work feeder 400. [

After the work, the conveying part 400 may be provided with a material guide rail 440 for guiding the material from the pick-up member to the seat part. The pick-up member is located at the upper portion of the post-work station 400 and the material guide rail 440 is provided at an inclined position to transmit the material from the upper portion to the post-work post-

The material guide rail 440 can be arranged to be inclined. The upper side of the material guide rail 440 is located below the pick-up member, and the lower side is located above the post-work conveying unit 400. At this time, the lower side of the material guide rail 440 is located at a certain distance from the mounting portion of the post-operation conveyance unit 400, thereby preventing interference with the materials conveyed along the post-operation conveyance unit 400.

After the work, the transfer unit 400 may include an escape prevention cover. The departure-avoidance cover may be located in the forward direction in the lower direction of the material guide rail 440. The departure prevention cover is provided to cover the upper portion of the post-work conveying part 400 and can prevent the material falling off the material guide rail 440 from colliding with the post-work conveying part 400 and escaping to the outside.

FIGS. 8 and 9 are views showing how a material moves to the material storage unit 500. FIG.
