Description

  The present invention relates to a workpiece transporting measure for transporting workpieces one by one.

  In order to process each workpiece one by one, the workpiece is conveyed while being repeatedly started and stopped by a chain conveyor or the like. And, for example, when transporting and painting a workpiece one by one, first, the workpiece is masked at locations other than the location to be painted, sprayed with a sprayer, or immersed, and the coating is dried. The work is performed in a high greenhouse, and the work is conveyed by a chain conveyor or the like that repeatedly starts and stops. And the work which dried has removed the masking and made it the product.

In the above workpiece transfer method, a start / stop control circuit is required, and a simple transfer device is desired.
In addition, the conventional coating method takes time and effort required for masking, and it is impossible to dry the paint in order, one by one, and the drying is slow even when the temperature is increased. is there.
In view of the above, the present invention provides a transporting device and the like for transporting workpieces one by one in order to eliminate such inconvenience.

  In the workpiece transfer device for transferring the workpieces of claim 1 one by one, a stop body that can be rotated is arranged on a pair of frames arranged at an appropriate interval in an inclined downward direction from upstream to downstream. Further, the stop body has a center of gravity on the upstream side with respect to the rotation axis, and when the stop body 10 has no workpiece, the upper edge portion 10c on the upstream side of the stop body 10 is at a position where the upper surface 3a of the frame 3 is below the upper surface 3a. On the other hand, the upper edge portion 10 d on the downstream side of the stop body 10 is attached so as to be above the upper surface 3 a of the frame 3. In addition, the center of gravity may be formed by adding a weight or the like in addition to forming the center of gravity in the shape of the wide portion 10a and the narrow portion 10b.

Therefore, the stop body 10 is located at a position where the upper edge portion 10c on the upstream side of the stop body 10 is equal to or lower than the upper surface 3a of the frame 3 when there is no workpiece support portion 1a. 10 d of upper edges are attached so that it may become above the upper surface 3a of the flame | frame 3 (FIG. 2 (B) (a)).
However, when the workpiece support 1 a is placed on the upstream upper edge 10 c of the stop body 10, the stop 10 rotates clockwise, and the upstream upper edge 10 c is connected to the upper surface 3 a of the frame 3. It becomes a more protruding state.
Therefore, when the work is placed on the frame from the upstream side, when there is no work on the downstream stop body 10, the work rolls to the downstream stop body 10, and the work is on the downstream stop body 10. At that time, it is held on the stop body 10 on the upstream side, so that each workpiece can be conveyed to the coating apparatus.

  According to a second aspect of the present invention, after the workpiece conveyed by the conveying device of the first aspect is clamped, the workpiece is lifted and applied with a rotatable clamping device and a rotatable coating tool. Since the paint is supplied dropwise, it can be applied with simple equipment without masking.

A workpiece transfer apparatus for transferring workpieces of claim 3 one by one to a stop body 100 in which a plurality of recesses 100b are formed by projections 100a and a pair of frames 3 that are inclined downward from upstream to downstream. The stop bodies 100 are arranged so as to be rotatable so as to alternately overlap on the upstream side and the downstream side, and the stop bodies are attached while being shifted in the frame direction.
With the arrangement of the stop bodies 100, when there is no workpiece 1 in the adjacent stop body 100 on the downstream side, the workpiece 1 is rotated by its own weight and sequentially moves to the downstream stop body 100 (FIGS. 5A to 5E). )). On the other hand, when the workpiece 1 is in the adjacent stop body 100 on the downstream side, the upstream stop body 100 is maintained in the stopped state because the rotation of the protrusion 100a is prevented by the work support portion 1a.
Therefore, the transport device having this configuration has a simple configuration and can arrange many workpieces with a short length by narrowing the interval between the stop bodies.

5. A workpiece conveying apparatus for conveying workpieces one by one, a stair support body in which recesses 152 supporting both ends of the work are formed in a step shape at pitch intervals, and the stair support body is a fixed stair support body. 151A and a combination of a fixed staircase support 151B and an adjacent rotating staircase support 151B inside the fixed staircase support 151A. The fixed stair support 151A is fixed to the frame, and the rotating stair support 151B rotates eccentrically at the pitch interval with respect to the fixed stair support 151A.
Since the workpiece is supported by the concave portions of the fixed staircase support 151A one by one by the eccentric rotation of the rotating staircase support 151B, a large number of workpieces can be obtained even at short distances. Can be arranged.

The workpiece transfer device according to claim 5 is provided with a support member 186 capable of supporting a workpiece support portion with respect to a workpiece in a stacked state in a retreat chamber provided with a stop body for stopping the workpiece at a downstream portion. The support member 186 is fixed to a cylinder rod that can be raised and lowered, and is provided on the discharge side so as to be inclined downward. Moreover, the buffer body 190 which stops the workpiece | work 1 in the evacuation chamber 180 is attached to the support member so that rotation is possible.
As the cylinder rod is raised and lowered, the support member 186 and the buffer body 190 are raised and lowered, and the workpiece 1 is brought into a stopped state by the buffer body 190. Since only one workpiece is placed on the support member 186 by raising and lowering the cylinder, the workpieces can be conveyed one by one.

The workpiece transfer device according to claim 6 is a device for sequentially picking up and transferring the listed workpieces 1 at a predetermined interval, and includes a rotating body 200 for forming a recess 201 for supporting the workpiece support 1a. Yes. And the said recessed part is formed in the downward inclined shape with respect to the discharge | emission side, and the fixing body is provided in the outer periphery of the rotary body 200 from the entrance which receives the workpiece | work 1 to an exit.
Therefore, when the workpiece support 1a rolls from the recess 201 at the entrance of the rotator 200, the rotator 200 rotates due to its own weight, and when it reaches the outlet, it is discharged from the recess by the downward inclination of the recess at the exit. For this reason, a workpiece | work can be conveyed one by one by rolling a workpiece | work to a rotary body sequentially.

  According to the transfer device of the present invention, it is possible to transfer workpieces one by one with a simple configuration.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a conceptual diagram showing the entire drying equipment of the present invention. In order to coat a workpiece, the workpiece conveying device 5 for conveying the workpiece 1 one by one, and receiving and coating the workpiece 1 from the conveying device 5. A workpiece carry-in movement device 20 that conveys to the device 40, a coating device 40 that includes the clamping device 30 and the coating tool 35, a workpiece discharge movement device 50 that conveys the workpiece 1 that has been coated to the drying chamber 60, and the drying chamber 60. It is a certain discharge device 70.

(Work transfer device 1)
The conveying device 5 for the workpiece 1 will be described with reference to FIG.
As for the shape of the work 1, the main body 1A is a round bar, and both ends form round bar support portions 1a that are thinner than the main body, and the support portions 1a at both ends of the thin round bar are not painted.
First, the workpieces 1 are heated to about 60 ° C. by a hot air device (not shown), and placed one by one on the workpiece transfer device 5.
The work transport device 5 is a device that transports the work 1 one by one without a power source, and the pair of frames 3 on which the support portion 1a of the work 1 is mounted and rolled are downstream from the upstream side. It is installed in a downward slope toward the side (conveyance destination).

In addition, the stop body 10 is processed so that, for example, the upstream side is wider than the width of the narrow portion 10b on the downstream side so that the center of gravity exists on the upstream side with respect to the rotating shaft 11 by processing an iron plate or the like. The wide portion 10a is formed in a substantially L shape, and is attached to the side portions of the pair of frames 3 so as to be rotatable by the rotation shaft 11, and the mounting interval of the stop body 10 takes the size of the workpiece into consideration. Select.
That is, when the stop 10 is not provided with the workpiece support 1a, the upper edge 10c on the upstream side of the stop 10 is positioned below the upper surface 3a of the frame 3. An upper edge portion 10d on the downstream side of the stop body 10 is formed so as to protrude from the upper surface 3a of the frame 3 (FIGS. 2B and 2A).
On the other hand, when the workpiece support 1a is on the upper edge portion 10d on the downstream side of the stop body 10, the state of the stop body 10 is that the upper edge portion 10c on the upstream side of the stop body 10 is the upper surface 3a of the frame 3. Further, the upper edge portion 10d on the downstream side of the stop body 10 is formed to be positioned below the upper surface 3a of the frame 3 (FIGS. 2B and 2C).

That is, the stop body 10 is rotated by the rotation shaft 11 with and without the workpiece 1, and the upstream upper edge portion 10 c and the downstream upper edge with respect to the upper surface 3 a of the frame 3. What is necessary is just to comprise so that the part 10d may protrude alternately.
Therefore, the stop body 10 itself does not need to be balanced by the rotation shaft 11, and the upstream side of the stop body 10 is formed to be heavier than the downstream side, and a stopper (not shown) is provided below the stop body 10. It may be configured to restrict the angle of rotation so that the upstream upper edge portion 10c and the downstream upper edge portion 10d protrude alternately with respect to the upper surface 3a of the frame.

The operation of the stopping body 10 will be described. When the support portion 1a of the work 1 is placed on the upper surface 3a of the frame from the upstream side, the work 1 moves from the upstream upper edge portion 10c to the downstream upper edge. Rolling to the portion 10d, the stopping body 10 is rotated clockwise around the rotation shaft 11, and the upper edge portion 10c on the upstream side is projected from the upper surface 3a of the frame (FIG. 2B). b)).
As described above, when there is no work on the downstream stop body 10, the work 1 of the upstream stop body 10 sequentially moves to the downstream stop body 10.

On the other hand, when the workpiece 1 is on the downstream stop body 10, the upstream upper edge portion 10 c of the downstream stop body 10 protrudes above the upper surface 3 a of the frame 3 and is placed on the upstream stop body 10. The support part 1a of the workpiece 1 is kept in contact with the wide part 10a of the stop body 10 (FIGS. 2B and 2C).
A stopper 13 is provided at the most downstream position of the conveying device 5 in order to prevent the workpiece 1 from rolling. The stopper 13 activates the cylinder 14 at a predetermined time interval. Then, the stopper 13 is lowered to adjust the speed (processing amount) at which each workpiece is conveyed.

As described above, the stop body 10 is arranged in a downwardly inclined manner toward the downstream side. When the work 1 is conveyed from the upstream side, the stop body 10 is sequentially rolled to the downstream stop body 10 to stop on the downstream side. When the work 1 is stopped by the body 10, the work 1 on the upstream side stops at that position.
Therefore, this conveying apparatus can convey the workpieces 1 one by one even without a driving source.

(Work loading / unloading device)
As shown in FIG. 3, the workpiece carry-in movement device 20 is a device that receives the workpiece 1 that rolls based on the raising and lowering of the stopper 13 from the conveying device 5 and conveys the workpiece 1 for setting in the coating device 40. .
In the work carry-in moving device 20, a liftable cylinder 22 is attached to a base 21 that can move in the front-rear direction and the left-right direction. The movement of the base 21 is a movement position for receiving the workpiece 1 from the transfer device 5 and setting it on the coating device 40, so that the movable direction and the like can be appropriately selected.
A horizontal stop body 23 is attached to the rod 22 a of the cylinder 22, and concave receiving portions 25 that support both ends of the work 1 are attached to the end of the stop body 23.

The operation of the workpiece carry-in moving device 20 will be described. The workpiece carry-in moving device 20 is located on the most downstream side of the transfer device 5 and accepts that the workpiece 1 stopped by the stopper 13 rolls. While moving to that position, the rod 22a is lowered.
Then, the cylinder 14 is activated at a predetermined time interval, the stopper 13 is lowered, and the workpiece 1 stopped by the stopper 13 is received by the receiving portion 25.
And the base 21 is moved and the workpiece | work 1 is conveyed to the predetermined position of the coating device 40. FIG.

(Coating equipment)
The painting device 40 includes a clamping device 30 and a painting tool 35.
The clamping device 30 includes a clamping tool 31 that clamps the support portion 1 a of the workpiece 1. The clamping device 30 can move left and right and move up and down, and can rotate the workpiece 1 that is clamped by the clamping tool 31. .
In addition, a pair of mutually rotating paint tools (rollers) 35 are installed on the upper part of the clamping device 30, and the paint drops from the storage can 36 onto the paint tool 35 like an infusion.

Next, the operation of the coating apparatus 40 will be described. The holding apparatus 30 prepares for receiving the workpiece 1 by moving the holding tool 31 in advance and widening the interval.
Then, the workpiece 1 conveyed by the workpiece carry-in moving device 20 is moved to below the clamping tool 31 and is lifted by a cylinder 22 provided in the workpiece carry-in moving device 20.
Next, the clamping tool 31 is moved to narrow the interval so as to clamp the workpiece 1, and then the cylinder 22 of the workpiece loading / unloading device 20 is lowered and separated from the bottom of the coating device 40, and the conveyance Return to the position where the workpiece 1 is received from the apparatus 5.
Next, the clamping device 30 is raised to rotate the workpiece 1, and the coating is applied to a predetermined portion with the rotating coating tool 35.
The temperature of the work 1 is about 60 ° C., and when the paint is applied and a preset time is reached, an instruction to convey the work 1 to the drying chamber is issued assuming that the painting is completed.

(Work discharge transfer device)
As described above, the workpiece discharge moving device 50 conveys the workpiece 1 that has been coated to the drying chamber 60, and has substantially the same configuration as the workpiece loading and moving device 20, and moves in the front-rear direction and the left-right direction. On a possible base 51, a cylinder 52 that can be moved up and down, a rod 52 a of the cylinder 52, a horizontal stop body 53, and a concave receiving portion 55 that supports both ends of the workpiece 1 at the end of the stop body 23. It is configured.

  When the painting of the workpiece 1 is completed, the workpiece discharging / moving device 50 is moved, moved below the workpiece 1, the rod 52a of the cylinder 52 is raised, and the support portion 1a of the workpiece is received by the receiving portion 55. Then, the holding tools 31 and 31 are moved to stop the holding, and after the work 1 is transferred to the receiving portion 55, the base 51 is moved to move to the discharge device 70 installed in the drying chamber 60.

(Drying room)
The drying chamber 60 is provided with a discharge device 70 in which a stop body 10 that supports the support 1a of the workpiece 1 similar to the workpiece transfer device 5 is disposed in a downward slope. Each device 70 is conveyed toward the discharge port one by one, and is dried in the conveyance process.
In addition, since the effect | action of this discharge device 70 is the same structure and effect | action as the said conveying apparatus 5, description is abbreviate | omitted. A stopper 71 that is moved up and down by a cylinder 72 is installed at the discharge port, and the movement of the cylinder 72 is synchronized with the movement of the cylinder 22.

The drying chamber 60 is formed by a cover 61 that covers the discharge device 70. In this drying chamber, dry air having a predetermined humidity (for example, humidity of 30% or less) or less is formed at the end of the cover 61 from the dry air device (not shown) through the pipe 63. The paint applied to the workpiece 1 is dried.
Further, inside the cover 61, a plurality of triangular prism-shaped diffusers 64 are arranged at appropriate intervals from the inlet of the dry air to the opposite side (upstream side of the workpiece), and the air in the drying chamber To diffuse.
As described above, when the workpiece 1 having a high temperature is dried in dry air, the drying speed is increased.

Next, a process of transporting the workpiece 1 to the drying chamber 60 by the workpiece discharge moving device 50 will be described.
First, the workpiece 1 transferred to the receiving portion 55 of the workpiece discharging and moving device 50 moves the base 51 and moves to the upstream portion of the discharging device 70, and then lowers the cylinder 52 to lower the workpiece 1. When the support portion 1 a is placed on the frame 3, the work 1 rolls on the frame 3.
If there is no work 1 on the downstream stop body 10, the process proceeds to the downstream stop body 10 in sequence, and if there is a work 1, the work stops at the stop body 10.
As described above, the workpieces in the drying chamber are discharged one by one by the workpiece discharge moving device 50 at a predetermined time, and the residence time is the drying time. Therefore, the drying time is determined by the raising / lowering time interval of the cylinder 52.

Next, in carrying out the coating of the workpiece 1 as described above, different conveying devices and the like capable of conveying each workpiece one by one will be described.
(Work transfer device 2)
This workpiece transfer device is an alternative to the stop body 10 shown in FIG. 2, and is composed of a stop body 100 as shown in FIG.
The stop body 100 is formed by a cross-shaped protrusion 100a, and receives the workpiece support 1a at four concave recesses 100b.
The upstream-side stop body 100 and the downstream-side stop body 100 are configured so that the upstream-side protrusion body 100a and the downstream-side protrusion body 100a overlap with each other, and the rotating shaft 101 provided on the downwardly inclined frame 3. The protrusions 100a and 100a are selected by the diameter of the support portion 1a of the workpiece 1.

The upstream stop body 100 and the downstream stop body 100 can be independently rotated, and the upstream protrusion body 100a and the downstream protrusion body 100a overlap each other. Therefore, the stop body 100 and the stop body 100 are attached so as to be shifted in the direction of the frame 3 (shifted in the front and back direction of the paper surface).
Since the interval between the stop body 100 and the adjacent stop body 100 can be selected by the diameter of the support portion 1a, it can be narrowed, and is the same as the transport apparatus configured using the stop body 10 shown in FIG. More workpieces 1 can be arranged even with a length.
Further, the stop body 100 can be rotated. However, when the work 1 is located on the adjacent stop body 100 on the downstream side, the rotation of the protrusion 100a of the upstream work is prevented by the support portion 1a of the work. So keep it stopped.

Next, the operation of the transport apparatus having the above-described configuration will be described. The stop body 100 can be rotated. When the work 1 is not present in the adjacent stop body 100 on the downstream side, the stop body 100 is rotated by its own weight. It moves to the stop body 100 sequentially (FIG. 5B (a to e)). Then, the workpiece 1 moves to the lowermost stop body 100 and stops at the stopper 13.
On the other hand, when the workpiece 1 is in the adjacent stop body 100 on the downstream side, the upstream stop body 100 is maintained in the stopped state because the rotation of the protrusion 100a is prevented by the work support portion 1a.
Therefore, when the stopper 13 is lowered, the work 1 rotates the stop body 100 and separates from the lowermost stop body 100, so that the upstream stop body 100 is rotated by its own weight, and downstream of the work body 1. Move to the stop body 100.

As described above, the transport device for the workpiece 1 is configured by the stop bodies 100 that can be alternately arranged, and when the downstream workpiece 1 moves downstream, the upstream workpiece moves downstream. In addition, since the protrusions 100a can be configured to overlap each other, many workpieces can be arranged at a narrow interval. Note that the interval at which each workpiece 1 is conveyed is determined by the elevation interval of the stopper 13.
In addition, although the stop body 100 is the structure which receives the support part 1a of a workpiece | work in the four recessed parts 100b, the number of these recessed parts 100b should just be two or more.

(Work transfer device 3)
This conveying apparatus 150 is installed in the drying chamber 60 and dries while conveying the workpieces after coating is completed, and will be described with reference to FIG.
The drying chamber 60 is covered with a cover 61 (not shown), and the drying chamber 60 is supplied with dry air having a predetermined humidity (for example, a humidity of 30% or less) or less to apply paint applied to the workpiece. dry.

The conveying device 150 conveys the workpieces 1 one by one sequentially at a predetermined time interval, and supports two supporting members 1a on both sides of the workpiece 1, and is a mountain-shaped staircase made of two plates having a predetermined width. A pair of supports 151 (151A, 151B) are installed.
In order to support the support portion 1a of the workpiece 1 at a pitch P selected by the diameter of the workpiece 1 in the direction from the upper edge portion 151a to the lower edge portion 151b, the mountain-shaped staircase support body 151 Recesses 152 having an inclination angle of about 45 ° are formed in a saw blade shape, six on the ascending side, six on the descending side, and V-shaped on the top.
The staircase support 151 is composed of a combination of a fixed staircase support 151A on the outside in plan view and a rotating staircase support 151B adjacent to the inside of the fixed staircase support 151A. The stair support 151 of the combination of the stair support 151A and the rotating stair support 151B is provided for the support portions 1a and 1a of the workpiece 1, respectively.

  The fixed stair support 151A is fixed to a frame (not shown). A rotating shaft 155 that rotates via a motor with a speed reducer (not shown) is attached to the frame on the vertical center axis of the fixed stair support 151A, and the rotating body 156 is attached to the rotating shaft 155. It is. Further, a support rod 160 is suspended from the rotating body 156 at a position eccentric by the pitch P, and the support rod 160 rotates about the rotation shaft 155.

On the other hand, the rotation stair support 151B is provided with a rotation hole 161 in the vertical center axis. The support rod 160 is inserted into the rotation hole 161, and the support rod 160 is rotated. It can rotate with respect to the hole 161.
Accordingly, when the rotating body 156 rotates with the rotation of the rotating shaft 155, the support rod 160 rotates about the rotating shaft 155, and the rotation stair support 151B is eccentric by the rotation of the support rod 160. Rotate.

Next, a process of sequentially transporting the workpieces 1 one by one by the transport device 150 having the above-described configuration will be described with reference to FIG.
(A) FIG. 7 (A)
It is assumed that the workpiece 1 is supported by the leftmost concave portion 152 of the fixed stair support 151A with the support 1a of the work 1 and the rotating stair support 151B is at the lowest position.
(B) FIG. 7 (B)
Next, when the rotating stair support 151B rotates 45 ° eccentrically in the clockwise direction, the leftmost recess 152 of the rotating stair support 151B is supported by the leftmost recess 152 of the fixed stair support 151A. The support part 1a is supported. That is, the workpiece 1 moves from the fixed stair support 151A to the rotating stair support 151B.

(C) Figure 7 (C)
When the rotating stair support 151B further rotates and rises most, the leftmost recess 152 of the rotating stair support 151B is positioned above the leftmost recess 152 of the fixed stair support 151A. .
(D) FIG. 7 (D)
When the rotating stair support 151B is further rotated, the rotating stair support 151B is lowered and is shifted to the right by 1 pitch P, and is supported by the leftmost recess 152 of the rotating stair support 151B. 1 is placed on the concave portion 152 one above the leftmost side of the fixed stair support 151A.

The above description of the transport process is for one workpiece. Even when the workpieces 1 are in all the recesses 152, each workpiece 1 has a rotating stair support 151B in the clockwise direction. When it rotates, it moves to the next recess 152.
As described above, in the transport device 150, when the rotating stair support 151 </ b> B rotates once in the clockwise direction, the right concave portion 152 adjacent to the concave portion 152 of the mountain-shaped stair support 151 is provided for each workpiece 1. In addition, it can be conveyed sequentially.
Therefore, when the same concave portions 152 are arranged in a flat shape with respect to the mountain-shaped staircase support 151 capable of transporting each workpiece, the overall length of the transport device is increased. In other words, the conveying device constituted by the mountain-shaped staircase support 151 can make the same concave portion 152 shorter than the number.

(Work transfer device 4)
With reference to FIG. 8 showing a cross-section, a conveying device for one workpiece 1 will be described in a state where a number of workpieces 1 that have been heated are stacked.
The workpiece 1 stacked in a holding chamber (not shown) is heated to about 60 ° C. by hot air. Then, the heated workpiece 1 is moved to the retreat chamber 180 whose bottom 180a is inclined downward.
Further, a stop body 183 is provided downstream of the retracting chamber 180 at a position where the main body 1A of the work 1 abuts.

In addition, cylinders 185 are installed on both sides downstream of the retreat chamber 180, and a workpiece support 1a is supported at the tip of the cylinder rod 185a that moves up and down to prevent the retreat chamber 180 from falling to the retreat chamber 180 side. Therefore, a bent portion is formed at the left end, and a downwardly inclined support member 186 is fixed to the discharge side (in the right direction) with bolts and nuts 185b.
Further, the support member 186 is attached with a buffer body 190 such as a plate that can be rotated by a rotation shaft 190 a and is brought into contact with and stopped by the main body of the work 1 in the retraction chamber 180. A rotating body 190b is attached to the other end of the retractable chamber 180 so as to roll on the bottom 180a of the retreat chamber 180.
That is, the buffer member 190 allows the support member 186 to move up and down without being obstructed by the workpiece 1 (support portion 1a).

Next, the operation of discharging each workpiece 1 using the mechanism having the above configuration will be described. When the cylinder 185 is in the lowered state, the workpiece 1 stacked in the retracting chamber 180 is shown in FIG. As shown in FIG. 3, the apparatus abuts on the downstream side of the stop body 183 and waits in a state of being placed on the buffer body 190.
Next, when the cylinder 185 is lifted to discharge one workpiece 1, the support member 186 is lifted while supporting the work support portion 1a at the bottom of the stacked workpieces, and is placed thereon. The placed workpiece 1 falls into the retreat chamber 180 without being supported. On the other hand, as the cylinder 185 rises, the buffer body 190 also rises and comes into contact with the rolling workpiece.
Then, when the work 1 is raised above the stop body 183, the work 1 is released from the stop state by the stop body 183, and rolls from the downward inclined support member 186 to the work transport device 187 downstream (FIG. 8 ( B)).

When the cylinder 185 is lowered to take out the next workpiece 1, the other end of the buffer body 190 moves toward the upstream side on the bottom 180 a of the retracting chamber 180 as the cylinder 185 is lowered. . Therefore, since the workpiece 1 is prevented from rolling by the buffer body 190, even if the support member 186 is lowered, the support member 186 can be lowered without coming into contact with the support portion 1a of the workpiece (FIG. 8B). ).
In addition, as the buffer body 190 is lowered, the work 1 at a location where the buffer body 190 is not present rolls toward the stop body 183 installed on the downstream side. When the cylinder rod 185a is lowered to a predetermined position, the original state is restored (FIG. 8A).
As described above, the support member 186 and the buffer 190 can be moved up and down to the stacked workpieces 1 one by one.

(Work transfer device 5)
As shown in FIG. 9, this workpiece transfer device is a device that sequentially picks up and transfers the arranged workpieces 1 one by one at a predetermined interval.
A rotating body 200 for forming a recess 201 for supporting the workpiece support 1 a is rotatably installed on both sides of the workpiece 1. Further, the recess 201 is formed at four locations around the periphery at equal intervals, and the shape of the recess 201 is inclined downward with respect to the discharge side.
Further, as will be described in detail later, the rotating body 200 rotates counterclockwise and a fixed body 202 is provided on the outer periphery of the rotating body 200 from the inlet (recess 201a) for receiving the workpiece 1 to the outlet (recess 201b). It is. This fixed body 202 is for enabling the workpiece 1 that has been rolled into the recess 201 to be transferred along with the rotating body 200 even when it is on the lower side.

  A receiving support 205 for supporting the workpiece support 1a is installed upstream of the position corresponding to the inlet (recess 201a) of the rotating body 200. The receiving support 205 is connected to the inlet (recessed portion 201a). It is formed in a downward inclined shape that can roll toward 201a). On the other hand, a discharge support 206 for supporting the workpiece support 1a is installed downstream of the position corresponding to the exit (recess 201b) of the rotating body 200. The discharge support 206 is connected to the exit (recess). 201b) is formed in a downward inclined shape that can roll.

The operation of the transport apparatus having the above-described configuration will be described. The workpiece 1 is arranged on the receiving support 205. And when the entrance (recessed part 201a) of the rotating body 200 comes, the work rolls and rolls into the recessed part 201. The rotating body 200 rotates counterclockwise by the weight of the work 1 (FIG. 9A).
And when the rotary body 200 rotates and the next entrance (concave part 201a) comes, the workpiece 1 is rolled into the concave part 201.
As described above, when the workpiece 1 sequentially reaches the entrance (concave portion 201a), the workpiece 1 rolls to the rotating body 200, and the rotating body 200 rotates by its own weight.

When the concave portion 201 of the rotating body 200 reaches the lowest position, the workpiece 1 is detached from the rotating body 200 and supported by the fixed body 202.
When the rotating body 200 further rotates and the concave portion 201 reaches the outlet (the concave portion 201b), the workpiece 1 is separated from the concave portion 201 by the downward inclined concave portion 201 and rolls to the discharge support 206. .
As described above, the rotating body 200 accepts the workpiece 1 on the one hand and discharges it on the other hand, thereby maintaining the rotation by the weight of the workpiece and cutting out and transporting the workpieces one by one at a predetermined interval. .

The rotating body can be rotated counterclockwise by the work 1 rolled to the left half recess 201, but the clockwise rotational moment can be obtained by the work 1 rolled to the right half recess 201. Therefore, the static moment does not rotate (FIG. 9B).
However, since an inertial force acts on the rotating body 200, as shown in FIG. 9C, the rotating body 200 is counterclockwise depending on the state when the work 1 is discharged and when the work 1 is received. Rotational moment is generated and the inertial force due to this rotation acts, so that workpieces can be received and discharged one by one.
