 The endless transfer device of the present invention has the above-described configuration. Therefore, the conveyed object can be slid by its own weight on the roller conveyer by the at least three roller conveyers and the raising means, and can be conveyed in a predetermined rotation direction in an endless loop shape. In addition, when the object is slid on the roller conveyor by its own weight, it is required to hold the stopped state at a required position by the operation of the stopper means, or to release the holding in the stopped state and slide the object by its own weight. Can be resumed.

[0010] The at least three roller conveyors form a transport path that makes one round (one round) of the transported object in the predetermined rotation direction.

The predetermined rotation direction can be selected and applied in either a clockwise direction or a counterclockwise direction.

[0012] The inclination angle inclining in the predetermined rotation direction can be variously set. The tilt angle may be a fixed type that is set in advance to a target tilt angle value, a variable type that can be variously changed to a target tilt angle value, or a fixed type that is alternately arranged in the predetermined rotation direction. It is possible to use one configured with a variable system and one configured with a variable system, or configured with at least three variable systems configured in an endless loop.

[0013] Note that even a large number of three or more roller conveyors that are inclined in a predetermined rotation direction and arranged in an endless loop shape can be used. In this case, when viewed from the plane side, they can be arranged in an endless loop shape such as a substantially rectangular shape, a substantially square shape, a substantially polygonal shape, a substantially circular shape, a substantially oval shape, and the like.

In short, the plurality of roller conveyors may be arranged in an endless loop shape. For example, those having different lengths are substantially rectangular, substantially square, substantially polygonal, substantially circular when viewed from the plane side. , A substantially oval, or the like. As the plurality of roller conveyors, those extending in a straight line, those extending in an arc shape, and the like can be used.

The inclination angle of the plurality of roller conveyors can be variously set according to the length in the longitudinal direction, but is preferably in the range of 2 ° to 15 °.

[0016] The plurality of roller conveyors include at least a fixed roller conveyor having a so-called fixed inclination angle having a preset inclination angle and making the inclination angle invariable, and a roller conveyor ahead of the predetermined rotation direction. When the end is at a position lower than the front end of the rear fixed roller conveyor, the rear end of the front roller conveyor can be swung upward by the lifting means to a position higher than the front end of the rear fixed roller conveyor, and Swing roller conveyors having a so-called variable tilt angle, which can swing downward toward the original position, can be alternately arranged along the predetermined rotation direction.

The ascending means includes a variable roller conveyor having a front (front end) side as a swing center, a rear (rear end) side as a swing end, and swingable at a high inclination angle, and swinging of the variable roller conveyor. A vertical drive device for raising and lowering the end can be used.

For example, a hydraulic cylinder device , An air cylinder device, an electric device, or the like can be used.

The stopper means can be installed at a plurality of positions along the longitudinal direction of one roller conveyor and at predetermined intervals.

Further, the stopper means may be a means having a movement control unit which is operated by the input signal and has a movement control unit which prevents movement of the object to be conveyed in the downward direction due to its own weight and cancels the movement. The movement control unit includes, for example, a stopper member that can be moved upward and immersed below a straight line connecting the top surfaces of the rollers of the roller conveyor in an inclined state, and a stopper member that projects. It is possible to use a device which is movable and immersible, that is, a drive unit for moving in both directions.

The stopper member has a stopper function for abutting on the object to be conveyed and holding the object in the inclined direction due to its own weight in a stopped state, and a self-weight of the object to be conveyed by releasing the stopper function. It has a function to restart the movement in the tilt direction due to.

As the stopper member, for example, a mechanism that reciprocates linearly when projecting to the upper position and immersing to the lower position, or a circle with the other end (tip) centered on one end as the center of rotation. A mechanism that reciprocates in an arc can be used.

The second front-side auxiliary roller conveyor 4b is inclined so that the front side in the counterclockwise rotation direction R10 becomes lower, and its inclination angle θ (see FIG. 3, horizontal position O to inclined straight line S position) is about 3 degrees. ° to 5 °. The inclination angle θ is not limited to the above case (the inclination angle value), but can be variously set in advance according to the purpose.

The first tilt angle variable roller conveyor 1a and the second tilt angle variable roller conveyor 1b (see FIG. 1, FIG. 3, and FIG. 4) are different from each other in that they are arranged in opposite positions that are 180 ° horizontally inverted. Since they have the same structure, they will be described simultaneously.

As shown in FIG. 8, the first tilt angle variable roller conveyor 1a and the second tilt angle variable roller conveyor 1b are supported at a predetermined height of the base 10 placed on the floor surface e. A roller holding member 11 of a predetermined length having one end 110 pivotally supported by the shaft, another end 111 swinging up and down around the support shaft 100, and a position intersecting the longitudinal direction of the roller holding member 11. A plurality of rollers 12 rotatably held at predetermined intervals.

The other end 111 of the roller holding member 11 is vertically swingably held by an air cylinder device 13 as a lifting means.

After being extended, reciprocating movement for immersion in the cylinder portion 130 can be performed.

When the telescopic rod 131 is extended (see the dotted line position in FIG. 8), the other end 111 of the roller holding member 11 is pushed up, and the first inclined angle variable roller conveyor 1a and the second inclined angle variable roller conveyor 1b are moved. The tilt angle θ1 (horizontal position O to tilt straight line S1 position) in which the front side in the counterclockwise rotation direction R10 is low can be maintained, and when the telescopic rod 131 is retracted (see the solid line position in FIG. 8), the first The variable tilt angle roller conveyor 1a and the second variable tilt angle roller conveyor 1b may be held at the horizontal position O or the tilt angle θ2 (the horizontal position O to the position of the straight line S2) where the rear side in the counterclockwise rotation direction R10 is lowered. it can. The inclination angle θ1 is approximately 2 ° to 4 °. The inclination angle θ2 is about 5 ° to 7 °. The tilt angle θ1 and the tilt angle θ2 are not limited to the above case (the tilt angle value), but can be set in advance according to the purpose.

The first rear side auxiliary roller conveyor 2a and the second rear side auxiliary roller conveyor 2b (see FIGS. 1, 3 and 4) are different from each other in that they are arranged in opposite positions which are turned 180 ° in the horizontal direction. Since they have the same structure, they will be described simultaneously.

The first rear auxiliary roller conveyor 2a and the second rear auxiliary roller conveyor 2b have a base 20 (see FIG. 3) mounted on the floor surface e and a predetermined length held by the base 20. The roller holding member 21 and the first inclined angle fixed roller conveyor 3a and the second inclined angle fixed roller conveyor 3b have the same inclination position as the inclination angle θ obtained by extending the inclined straight line S2 at the front end side and the rear end side thereof. And a plurality of rollers 22 rotatably held at predetermined positions at positions intersecting the longitudinal direction of the roller holding member 21.

The first inclined-angle fixed roller conveyor 3a and the second inclined-angle fixed roller conveyor 3b (see FIGS. 1, 3, and 4) are different from each other in that they are arranged in opposite positions that are 180 ° horizontally inverted. Since they have the same structure, they will be described simultaneously.

The first inclined angle fixed roller conveyor 3a and the second inclined angle fixed roller conveyor 3b are held by the base 30 (see FIG. 3) placed on the floor surface e and the base 30 at an inclination angle θ. A roller holding member 31 of a predetermined length, a plurality of rollers 32 rotatably held at a position intersecting the longitudinal direction of the roller holding member 31 at a predetermined interval, and a plurality of rollers 32 installed at predetermined intervals. And stopper means.

The stopper means stops the object to be slid on the roller 32 by its own weight and stops it at the stop position, and releases the stopper function to restart the object to be slid by its own weight. A release function.

As the stopper means, a stopper device 6 shown in FIGS. 5, 6, and 7 is used. The stopper device 6 includes a drive motor 60, a stopper member 61, a timer (not shown), and a switch 62.

The drive motor 60 is attached to the base 30, and one end of a stopper member 61 is mounted on a rotation shaft 600 thereof, so that the drive motor 60 can rotate in the forward and reverse directions and hold the rotation.

The stopper member 61 is a thick plate, and the other end (tip) extending outward from the one end in the radial direction of the rotating shaft 600 is moved about 90 degrees in the forward and reverse directions in conjunction with the rotation of the rotating shaft 600. It can swing to a position protruding above the inclined straight line S (a position where the stopper function is obtained) and a position hidden below (a position where the stopper function is released).

After the stopper member 61 has moved from the position where the stopper member 61 protrudes above the inclined straight line S to the position where it is hidden below the inclined straight line S, the timer moves in accordance with the elapse of a preset time (about 6 to 8 seconds). Thus, the drive motor 60 can be operated in the reverse rotation operation, that is, the return rotation operation by a predetermined amount so as to return to the original upright position.

The switch 62 is provided on each of the worktables F1, F2, F5, and F6 required for operating the drive motor 60.

Prior to using the endless transfer device A configured as described above, a plurality of operations are performed along the counterclockwise rotation direction R10 (see FIG. 1) on the outer peripheral side of the transfer path R1 (see FIG. 2). The tables E1, E2 and the work tables F1 to F7 are installed at predetermined intervals.

It is to be noted that an unillustrated transported object [(a processing target member or a processed member) is not shown using the endless transporting apparatus A of the embodiment. same as below. ] Along the transport path R1 and slid by its own weight in the counterclockwise rotation direction R10, and transported to any of the worktables F1 to F7 corresponding to the target work process position, on each roller conveyor. The partition member 9 (see FIG. 4) which moves while being placed is also used.

The partition member 9 has a plurality of storage spaces 92 with a plate-shaped bottom 90 and a plurality of walls 91 standing upright at a predetermined interval from the bottom 90.

When the endless transport device A is used, the height of the first tilt angle variable roller conveyor 1a beforehand in the counterclockwise rotation direction R10 is set to the second front auxiliary roller conveyor 4b and the second tilt angle fixed roller. It is held by the air cylinder device 13 so as to be at the position of the inclination angle θ2 slightly lower than that of the conveyor 3b.

The two-inclination-angle variable roller conveyor 1b has a slightly lower inclination on the rear side in the counterclockwise rotation direction R10 than the first front-side auxiliary roller conveyor 4a and the first inclination-angle fixed roller conveyor 3a. It is held by the air cylinder device 13 so as to be at the angle θ2.

In this state, the transporting object is stored in the storage space 92 of the partition member 9 (see FIG. 11) placed on the second front-side auxiliary roller conveyor 4b at the transfer start position also serving as the transfer end position. Is done.

When the switch of the worktable F 7 is pressed, the cylinder portion 130 of the air cylinder device 13 performs the forward operation, and the telescopic rod 131 moves forward in the extending direction. As the telescopic rod 131 extends, the other end 111 of the roller holding member 11 is pushed up. The first tilt angle variable roller conveyor 1a is held at the tilt angle θ1 position where the front side in the counterclockwise rotation direction R10 is low and the rear side is high (see FIGS. 3 and 12).

When the telescopic rod 131 is extended, the partition member 9 is moved from a position (see FIG. 11) mounted on the second front side auxiliary roller conveyor 4b to a position higher than the first front side auxiliary roller conveyor 4b. As shown in FIG. 12, the roller 12 is lifted and placed by the first roller 1a, slides on the roller 12 by its own weight along the inclination angle θ1, and moves above the first rear auxiliary roller conveyor 2a. At this time, the first variable-angle roller conveyor 1a is held in an inclined state in which the front side in the counterclockwise rotation direction R10 is slightly higher than the first rear-side auxiliary roller conveyor 2a.

Then, the transported object is moved to the left side position (see FIG. 12) of the first variable-angle roller conveyor 1a (see FIG. 12), and the transfer object is transferred from the partition member 9 located above the first rear-side auxiliary roller conveyor 2a to the worktable E1. After being processed at the work tables E1 and E2, the work table E2 is returned to the storage space 92 of the partition member 9. Alternatively, the object to be transported is taken out of the partition member 9 to the work table E1, and at the same time, the previously processed object to be transported in the work table E2 is returned to the storage space 92 of the partition member 9.

Next, the cylinder portion 130 of the air cylinder device 13 is operated again, and the telescopic rod 131 is moved backward in the contracting direction. As the telescopic rod 131 contracts, the other end 111 of the roller holding member 11 descends. Then, the first tilt angle variable roller conveyor 1a is held at a tilt angle θ2 in which the rear side in the counterclockwise rotation direction R10 is low (see FIGS. 4 and 13), and the rear side in the counterclockwise rotation direction R10 is the second side. It is held in an inclined state slightly lower than the front auxiliary roller conveyor 4b.

When the telescopic rod 131 contracts, the partition member 9 is moved to a position slightly lower than the position (see FIG. 12) placed on the first variable-angle roller conveyor 1a (see FIG. 12). 2a (see FIG. 13).

The partition member 9 slides on the roller 32 of the first inclined angle fixed roller conveyor 3a by its own weight from the roller 22 of the first rear side auxiliary roller conveyor 2a and moves by itself, and the stopper member 61 of the device 6 It stops at the contact position (see FIGS. 4 and 5).

The transferred object (member to be processed) accommodated in the accommodating space 92 of the partition member 9 at this position is transferred to the worktable F1 (see FIG. 1), subjected to a predetermined processing step, and then subjected to the transferred object ( The primary processed member) is returned to the storage space 92 of the partition member 9, and the operation switch 62 of the worktable F1 is pressed.

Then, the drive motor 60 of the stopper device 6 is operated, and the stopper member 61 swings clockwise by about 90 ° from a position protruding above the inclined straight line S shown in FIG. 5 (a position where the stopper function is obtained). Then, it moves to a position hidden below the inclined straight line S shown in FIGS. 6 and 7 (a position where the stopper function is released).

For this reason, as shown in FIG. 6, the partition member 9 slides and moves on the roller 32 by its own weight, and passes above the stopper member 61 while maintaining a small distance L with respect to the stopper member 61. The stopper member 61 at the position where the stopper function is released is returned to the upright position where the original stopper function can be obtained by the reverse rotation of the drive motor 60 by a predetermined amount by the operation of the timer after the passage of the partition member 9. I do.

On the other hand, the partition member 9 that has passed above the stopper member 61 stops at the position of the next stopper member 61 (see FIG. 4) of the first inclined angle fixed roller conveyor 3a.

The transferred object (primary processed member) accommodated in the accommodating space 92 of the partition member 9 at this position is transferred to the worktable F2 (see FIG. 1), subjected to a predetermined processing step, and then transferred. The object (secondarily processed member) is returned to the storage space 92 of the partition member 9, and the operation switch 62 of the worktable F2 is pressed. Then, as in the case where the operation switch 62 of the work table F1 is pressed, the stopper device 6 operates and the moving state of the partition member 9 is obtained.

Then, the partition member 9 moves onto the first front-side auxiliary roller conveyor 4a disposed at the same inclination angle θ in front of the first inclination-angle fixed roller conveyor 3a.

When the partition member 9 is placed on the first front auxiliary roller conveyor 4a (see FIG. 11), the switch 14 of the worktable F3 is pressed.

When the partition member 9 is placed on the second front side auxiliary roller conveyor 4b, the first inclination angle variable roller conveyor 1a, the first rear side auxiliary roller conveyor 2a, the first inclination angle In the same manner as when moving on the first front auxiliary roller conveyor 4a in the order of the fixed roller conveyor 3a, the second inclined angle variable roller conveyor 1b, the second rear auxiliary roller conveyor 2b, and the second inclined angle fixed roller conveyor are arranged. It moves in the order of the second front auxiliary roller conveyor 4b in the order of 3b.

The process of moving the partition member 9 from the first front auxiliary roller conveyor 4a to the second front auxiliary roller conveyor 4b is performed by the work on the worktables F4, F5, F6 and the finished product on the worktable F7. Except for performing the inspection step described above, the process is the same as the process of moving from the second front-side auxiliary roller conveyor 4b to the first front-side auxiliary roller conveyor 4a, and therefore is shown in FIGS.

As described above, according to the endless transport device A of the embodiment, the transported object (the processing target member and the processed component) is moved to a predetermined position in the counterclockwise rotation direction R10 along the transport path R1. In the case of conveyance, the first inclined angle variable roller conveyor 1a, the first rear auxiliary roller conveyor 2a, the first inclined angle fixed roller conveyor 3a, the second inclined angle variable roller conveyor 1b, the second rear auxiliary roller conveyor 2b, The two-inclination-angle fixed roller conveyor 3b and the second front-side auxiliary roller conveyor 4b can be slid together with the partition member 9 by their own weight.

For this reason, in the case of the endless transfer device A of the embodiment, the worker moves the carriage 8 without manually moving the carriage 8 (see FIG. 15) as in the conventional case. Work costs can be reduced.

In addition, for each area of each work process, the worker of each work process concentrates on the work work on the work tables E1, E2 and the work tables F1 to F6 through the transfer path R1 and the inspection work on the work table F7. And work efficiency can be improved.
