To explain sequentially, the roller 2 with a built-in motor is
For example, it is sold by Ito Electric Co., Ltd. under the trademark of Power Mora, and a reduction gear (not shown) including a motor (not shown) and a planetary gear train inside the cylindrical body 12.
Is built-in. The central shafts 15, 16 protrude from both ends of the cylindrical body 12 as shown in FIG. The roller 2 with a built-in motor is normally used as a roller of a roller conveyor, and is used by fixing the center shafts 15 and 16 to a frame of the conveyor. Then, the motor built in the cylinder 12 is energized to rotate the cylinder 12. That is, the motor built-in roller 2 is provided with the central shafts 15 and 16
When the motor is energized in a state where is fixed, the outer cylindrical body 1
2 rotates. The roller 2 with a built-in motor is a roller that rotates the cylinder 12 relatively to the center shafts 15 and 16 by energization.
The central shafts 15, 16 will rotate.

The rotation axis changing mechanism 4 changes the rotation to a rotation about an axis intersecting the rotation axis and transmits the rotation. More specifically, the rotation axis changing mechanism 4 is a device in which the rotation axis on the input side and the rotation axis on the output side are orthogonal. In the present embodiment, the rotation axis changing mechanism 4 includes an umbrella-shaped friction wheel 20,
Groove 23 provided in intermediate friction wheel 22 and drive side pulley 5
Composed of

The endless belt 7 is an annular belt made of rubber or resin.

The support member 8 includes a top surface 25 and left and right side surfaces 2.
It is a box-shaped member having 6 and 27. The top surface 25 of the support member 8 has a sled shape, and both ends are curved downward as shown in FIG.

Next, the relationship between the members will be described. The motor built-in roller 2 is supported by a frame (not shown) by brackets 30 and 31. Bracket 3
Reference numerals 0 and 31 rotatably support the center shafts 15 and 16 of the roller 2 with a built-in motor.

A drive pulley 5 and a driven pulley 6 are disposed at both ends of the motor built-in roller 2. The rotating shafts of the driving pulley 5 and the driven pulley 6 are both orthogonal to those of the roller 2 with a built-in motor. Drive side pulley 5
, The driven pulley 6 is rotatably supported by a frame (not shown), but the driven pulley 6 can also move in a direction approaching / separating from the driving pulley 5.
That is, the driven pulley 6 can change the distance between the shafts with respect to the driving pulley 5.

The rotating shaft changing mechanism 4 is provided between the center shaft 15 of the motor built-in roller 2 and the driving pulley 5. The central shaft 15 of the motor built-in roller 2 is connected to the umbrella-shaped friction wheel 20 of the rotation shaft changing mechanism 4. An intermediate friction wheel 22 is engaged with both the friction surface of the umbrella-shaped friction wheel 20 and the groove 23 of the driving pulley 5.

On the other hand, the spring 9 is in contact with the shaft of the driven pulley 6, and the driven pulley 6 is constantly pressed in the direction in which the distance between the shafts increases.

The support member 8 is covered so as to cover the roller 2 with a built-in motor. That is, the warped top surface 25 covers the upper side of the motor built-in roller 2, and the left and right side surfaces 26 and 27 cover the side surfaces of the motor built-in roller 2.

The endless belt 7 is suspended between the driving pulley 5 and the driven pulley 6 described above. In a state where the respective members are assembled, the motor built-in roller 2 and the rotation axis changing mechanism 4 are in a space surrounded by the endless belt 7, and the center shaft 15 of the motor built-in roller 2 is moved through the rotation axis changing mechanism 4. It is engaged with the driving pulley 5. The warped top surface 25 of the support member 8 is located between the motor built-in roller 2 and the back surface of the endless belt 7.

As shown in FIG. 3, the transport device 1 of the present embodiment is provided at a portion (branch portion) of the conveyor line of one roller conveyor 32 where the branch line 33 is provided.
That is, the roller conveyor 32 has a built-in motor roller 34.
Are arranged in parallel. In the present embodiment, the three transfer devices 1 of the present embodiment described above are arranged in the gap between the motor built-in rollers 34. Here, since the entire width of the transport device 1 of the present embodiment is substantially equal to the width of the endless belt 7, the transport device 1 can be easily accommodated in the gap between the motor built-in rollers 34 of the roller conveyor 32. Also, since the overall height is low, installation is possible even when there is no room in the lower space of the roller conveyor 32.

The transport device 1 of this embodiment is located in the gap between the motor built-in rollers 32 as described above, and the projection of the cam 3 is always at the lower position as shown in FIG. The warped top surface 25 of the support member 8 is located at the lower fulcrum.

When the articles to be discharged to the branch line 33 reach the branch portion of the roller conveyor 32, the motor in the motor built-in roller 2 is energized. As a result, the cylindrical body 12 of the motor built-in roller 2 rotates, and the cam 3 attached to the cylindrical body 12 rotates. In designing, it is desirable to apply resistance to the center shafts 15 and 16 so that the cylinder 12 rotates preferentially when the motor is energized. The cam 3 contacts the inside of the top surface 25 of the support member 8 and pushes the top surface 25 upward. As a result, the support member 8 rises, and the sled-shaped top surface 25 presses the running surface of the endless belt 7 upward. Here, in the present embodiment, the driven pulley 6
The distance between the shafts with respect to the driving pulley 5 may vary. Therefore, when the support member 8 presses the running surface of the endless belt 7 upward, the driven pulley 6 moves in a direction in which the distance between the shafts is reduced against the pressing force of the spring 9, and the running surface of the endless belt 7 is Move up.

That is, the cylindrical body 12 of the motor built-in roller 2
Absolutely rotates, the cam 3 rotates together with the cylindrical body 12 to push up the support member 8 and push a part of the endless belt 7 outward. As a result, the running surface of the endless belt 7 rises, and is further exposed from the motor built-in roller 52 of the roller conveyor 50 to scoop up articles.

When the support member 8 reaches the highest point, the cam 3 cannot rotate any more, and the rotation of the cylindrical body 12 of the motor built-in roller 2 stops. Here, in the roller 2 with a built-in motor, since the cylindrical body 12 and the central shafts 15 and 16 rotate relatively, when the rotation of the cylindrical body 12 stops, the central shafts 15 and 16 absolutely rotate. as a result,
The drive pulley 5 rotates via the rotation axis changing mechanism 4, and the endless belt 7 starts running. Therefore, the articles on the conveyor line 32 move in the horizontal direction and move to the branch line 33 side.

When the transfer of the article is completed, the roller 2 with built-in motor is rotated in the reverse direction, the support member 8 is lowered, and the running surface of the belt is sunk.

In the embodiment described above, a belt is used as an endless long object, and a pulley is employed as a member for driving the belt. However, a chain and a sprocket can be used instead of the belt. Further, in the above-described embodiment, the example in which the rotating shaft changing mechanism 4 is configured by the umbrella-shaped friction wheel 20, the intermediate friction wheel 22, and the groove 23 provided in the driving pulley 5 is shown. The reason why the present embodiment employs the transmission by friction is to release a force when an overload is applied to prevent breakage of each member. The reason why the intermediate friction wheel 22 is used is to take into consideration the fact that the motor built-in roller 2 and the driving pulley 5 move due to play, and to absorb such play. However, if there is little play in mounting the motor built-in roller 2 and the driving pulley 5, a bevel gear, a worm gear, or the like can be used.

In this embodiment, the rotation of the cylinder 12 is stopped by moving the support member 8 to the upper limit.
The rotation of the cylinder can be stopped by other measures.

As shown in FIG. 5, a cam 38, a stopper plate 39 and a sliding body 61 of a height guide 40 are sequentially attached to the center shafts 15, 16 protruding from both ends of the motor built-in roller 2. In other words, the hexagonal central shafts 15 and 16 of the motor built-in roller 2 are
It is inserted through a hexagonal through hole 56 provided in the cam 38. A hexagonal shaft and a hexagonal through hole 56 are fitted to the center shafts 15, 16 and the cam 38, and the two do not allow relative rotation.

A ball bearing 86 (hereinafter referred to as a cam surrounding shaft ball bearing) is mounted on the outer periphery of the cam 38 mounted on the central shafts 15 and 16 of the motor built-in roller 2. The cam surrounding ball bearing 86 is arranged in the lateral guide 41. That is, the cam surrounding ball bearing 86 is within the rectangular frame of the lateral guide 41, and the horizontal members 68, 68
Always in contact with the inner surface of The cam surrounding ball bearing 86 described above is provided to reduce the contact resistance between the lateral guide 41 and the cam 38. Therefore, in practice, the cam 38 and the cam-surrounding ball bearing 86 function integrally as a cam, and it can be said that the cam and the body are integrated. In the present embodiment, ball bearings are used to reduce the contact resistance between the lateral guide 41 and the cam 38, but other bearings can be used. Of course, the member can be omitted.

As described above, a cover member (not shown) is provided on the front and back surfaces of the
8 and the cam surrounding ball bearing 86 do not fall off the lateral guide 41. As described above, the cam surrounding ball bearing 86
Are located in the rectangular frame of the lateral guide 41 and are always in contact with the inner surfaces of the horizontal members 68, 68. Therefore, the cam 38 and the cam-encircling ball bearing 86 have a degree of freedom only in the horizontal direction, Can not move to

The horizontal guide 41 is attached to the fixed frame 37. A projection (stopper) 69 projecting from the lateral guide 41 projects toward the stopper plate 39 side.

Further, the center shafts 15, 1 of the motor built-in roller 2
A stopper plate 39 is attached to a portion on the tip side of the cam attachment portion 6. Stopper plate 3
Also in the case of 9, the hexagonal shaft and the hexagonal through hole 58 are fitted, and they do not rotate relative to each other. Therefore, the stopper plate 39 rotates synchronously with the center shafts 15 and 16 of the motor built-in roller 2 and the cam 38 described above. In addition, the protrusion (stopper) 69 protruding from the lateral guide 41 is
The protrusion protrudes into the rotation locus of a protrusion 57 provided on the periphery of the stopper plate 39.

Further, the distal ends of the center shafts 15 and 16 are inserted through the slide 61 of the height guide 40. As described above, the ball bearing 65 is fitted into the sliding body 61, and the distal ends of the center shafts 15 and 16 of the motor built-in roller 2 are inserted into the inner race of the ball bearing 65. Therefore, the center shafts 15 and 16 of the motor built-in roller 2 and the sliding body 61 allow relative rotation.

As described above, the sliding member 61 of the height guide 40 can move only along the column member 62 of the outer frame member 60, and in this embodiment, the column member 62 is erected in the vertical direction. Therefore, the sliding body 61 moves only in the vertical direction. The same applies to the center shafts 15 and 16 of the motor built-in roller 2 inserted in the sliding body 61, and can be moved only in the vertical direction.

The outer frame member 60 side of the height guide 40 is attached to the fixed frame 37, and the slide 61 is attached to the horizontal transport section 43.

Looking at the positional relationship between the roller 2 with a built-in motor and the lateral transport section 43, there is a row of rollers 73 for the horizontal transport of the lateral transport section 43 right above the roller 2 with a built-in motor. The axis and the projection line overlap with the axis of the motor built-in roller 2. As described above, the annular grooves 59 are provided near both ends of the cylindrical body 12 of the motor-equipped roller 2. The transfer rollers 73b and 73e are located. The belt 44 is suspended between the annular groove 59 provided near both ends of the cylindrical body 12 and the V-groove 81 at the center of each of the lateral transport rollers 73b and 73e located immediately above the annular groove 59.

Here, the rotational grooves of the annular groove 59 of the cylindrical body 12 of the roller 2 with built-in motor and the lateral transport rollers 73b and 73e have an intersecting relationship (more precisely, a staggered relationship).
The V-groove 81 and the V-groove 81 are in a twisted position, but in the present embodiment, the belt 44 is suspended between them in a cross-like manner. That is, the annular groove 59 of the cylindrical body 12 and the lateral transport roller 73
Although b and 73e are staggered and twisted, the vertical lines passing through the centers of the two coincide. In addition, the V-groove 81 at the center of the lateral transport rollers 73b and 73e is deep. Therefore, although the belt 44 is slightly twisted, the annular groove 59 is formed.
The power can be transmitted between the V-groove 81 and the central V-groove 81 without being separated. That is, in the present embodiment, the belt 44 suspended at the twist position serves as a rotation axis changing mechanism.

Therefore, in the present embodiment, when the cylindrical body 12 of the roller 2 with built-in motor rotates, the belt 44 travels, and the horizontal transfer rollers 73b and 73e, which are power input members, rotate. Then, since all the lateral transport rollers 73a to 73f are linked by the belts 83a to 83e, when the cylindrical body 12 of the motor built-in roller 2 rotates, all the horizontal transport rollers 73a to 73f of the lateral transport unit 43 are synchronously driven. To rotate.

The cylinder-side resistance member 42 is located above the cylindrical body 12 of the roller 2 with a built-in motor.
Is in contact with the cylindrical body 12 of the roller 2 with a built-in motor. Then, the pin-shaped projection 71 of the cylinder-side resistance member 42 is inserted into a holding hole (not shown), and a nut is engaged with a screw portion on the upper part thereof. Therefore, the cylindrical resistance member 42 can be moved up and down by using the pin-shaped projection 71 as a guide, but does not come off. As shown in FIG. 5, a spring 90 is inserted into the pin-shaped projection 71, and the semicircular cutout 70 is constantly pressed against the cylindrical body 12 of the roller 2 with a built-in motor. Therefore, the cylinder-side resistance member 42 always applies a constant resistance to the cylinder 12 of the roller 2 with a built-in motor.

As in the previous embodiment, the transport device of this embodiment is also provided at a portion (branch portion) of the conveyor line of one roller conveyor 32 where the branch line 33 is provided as shown in FIG. . That is, the motor built-in roller 3
The transport device 35 of the present embodiment described above in the gap between the four
Is arranged. FIG. 7 shows an example in which two conveyors 35 according to the second embodiment are arranged at a branch part of a conveyor line (a horizontal conveyor line is not shown). Transport device 3 of the present embodiment
5, the entire width is substantially equal to the width of the roller with a built-in motor 34.
Fits comfortably in the gap between each other.

Next, the operation of the transport device 35 of this embodiment will be described with reference to FIGS. FIG. 15 is an explanatory view showing the operation of the transport device 35 of the present embodiment as described above. The roller 2 with a built-in motor, the cam 38, the cam-encircling ball bearing 86, the lateral guide portion 41, and the height guide 3 illustrates a positional relationship among the member 40, the lateral conveyance unit 43, and the roller conveyor 32. That is, the great circle indicates the cylindrical body 12 of the roller 2 with a built-in motor, and the smallest circle indicates the central axes 15 and 16 of the roller 2 with a built-in motor. Also, the central axis 15,1
An eccentric circle outside of 6 indicates cam 38. Further, a circle surrounding the cam 38 indicates a cam surrounding shaft ball bearing 86.

The parallel lines extending in the vertical and horizontal directions indicate the horizontal guide portion 41 and the height guide member 40. In the conveying device 35 of the present embodiment, as described above, the cam surrounding ball bearing 86 is in the rectangular frame of the lateral guide 41 and is always in contact with the inner surfaces of the horizontal members 68, 68.
8 and the cam surrounding shaft ball bearing 86 have a degree of freedom only in the horizontal direction, and cannot move in the vertical direction. Further, as described above, since the sliding member 61 of the height guide 40 can move only along the column member 62 of the outer frame member 60, the center shafts 15, 16 of the motor built-in roller 2 inserted into the sliding member 61 It can be moved only in the vertical direction. Further, the horizontal transport section 43
Is connected to the sliding body 61, so that the
Moves with the movement of the center shafts 15 and 16 of the roller 2 with a built-in motor.

FIG. 16 is an explanatory view showing the operation of the transport device 35 of the present embodiment at the time of normal rotation as described above. The central shafts 15 and 16 of the roller 2 with built-in motor, the stopper plate 39 and the stopper ( (Projection) 69 is shown. That is, the central hexagon is the roller 2 with a built-in motor.
Are shown as the central axes 15, 16. A circle having a protrusion 57 around the circumference indicates the stopper plate 39. The outer square is the lateral guide 41, and the double circle at the bottom is a stopper (projection) 69.

In the transfer device 35 of this embodiment, the cam 38
And the cam surrounding ball bearing 86 is within the rectangular frame of the lateral guide 41 and cannot move in the vertical direction. Also, since the lateral guide 41 holding the cam 38 and the cam surrounding ball bearing 86 is attached to the fixed side frame 37,
The height of the central shafts 15 and 16 of the motor built-in roller 2 which is the rotation axis of the cam 38 and the cam surrounding ball bearing 86 is determined by the posture (rotation angle) of the cam 38.

Further, as described above, the center shafts 15 and 16 of the motor built-in roller 2 are
And the sliding member 61 can be moved only in the vertical direction.
5 and 16 can move only in the vertical direction. Therefore, by the action of the lateral guide 41 and the height guide 40, the center shafts 15, 16 of the roller 2 with built-in motor have a degree of freedom only in the height direction. Furthermore, the central shaft 1 of the roller 2 with a built-in motor
The heights of 5 and 16 are determined only by the posture (rotation angle) of the cam 38. Further, the horizontal transport unit 43 includes a sliding body 61.
Are connected to the central shafts 15 and 16 of the roller 2 with built-in motor, so that the height of the lateral conveying portion 43 is also determined only by the posture (rotation angle) of the cam 38.

The conveying device 35 of the present embodiment is located in the gap between the motor built-in rollers 32 as described above, and the cam 38 always has the protruding portion at the upper position as shown in FIG. . That is, the center shafts 15, 16 of the motor built-in roller 2, which is the rotation shaft of the cam 38, are located at the lower part. Therefore, the horizontal transport section 43 is also at a low position, and the horizontal transport rollers 73 of the horizontal transport section 43 are all sunk below the top of the conveyor line. At this time, the stopper plate 39 is at a rotation angle at which the protrusion 57 is located at the upper right portion as shown in FIG.

When the articles to be discharged to the branch line 33 reach the branch portion of the roller conveyor 32, the motor 45 in the motor built-in roller 2 is energized. When the motor 45 is energized, one of the cylindrical body 12 and the center shafts 15 and 16 rotates. In the case of the above-described timing, the center shafts 15 and 16 rotate preferentially.

That is, in the transfer device 35 of this embodiment,
The cylindrical body-side resistance member 42 is attached to the cylindrical body 12 of the motor built-in roller 2.
The cylindrical body-side resistance member 42 is constantly pressed toward the cylindrical body 12 by the spring 90. Therefore, a considerable load resistance is applied to the cylindrical body 12 and it is difficult to rotate. On the other hand, since the center shafts 15 and 16 have relatively low resistance, the cylindrical body 12 having high resistance stops, and the center shafts 15 and 16 having light resistance rotate. As a result, the cam 38 integrally and integrally attached to the center shafts 15, 16 is shown in FIG.
Rotate as in (c). As described above, the horizontal transport unit 43
Is determined only by the posture (rotation angle) of the cam 38, but the cam 38 rotates to reach a horizontal position as shown in FIG. 15B, and the rotation further proceeds. As shown in FIG. 15C, in the process in which the protruding portion of the cam 38 reaches the upward position, the positions of the center shafts 15, 16 gradually increase. As a result, the horizontal transport section 43 gradually rises, and finally the horizontal transport rollers 73 of the horizontal transport section 43 protrude from the top of the conveyor line and scoop up articles.

On the other hand, the stopper plate 39 is
Since they are integrally fixed to the cams 5 and 16, they rotate synchronously with the cam 38. That is, when the protruding portion of the cam 38 reaches the horizontal position as shown in FIG.
The protrusion 57 reaches the stopper plate 39 at a substantially horizontal position as shown in FIG. Further, when the center shafts 15 and 16 further rotate and the posture of the cam 38 becomes as shown in FIG. 15C, the protrusion 57 of the stopper plate 39 reaches the lower right position as shown in FIG. It collides with the projection 69. As a result, extremely large resistance is applied to the center shafts 15 and 16, and rotation of the center shafts 15 and 16 is prevented.

When the motor 45 is energized as described above, the cylindrical body 12 and one of the central shafts 15 and 16 rotate, but the protrusion 57 of the stopper plate 39
Since the central shafts 15 and 16 cannot rotate at all when they come into contact with the stoppers (projections) 69 as shown in FIG.
2 starts rotating the cylindrical body 12 of the roller 2 with built-in motor.

As a result, the belt 4 suspended on the cylindrical body 12
4 travels and the rollers 73b, 73 for lateral conveyance as power input members.
3e, and transmits all rotation rollers 73a to 73 of the horizontal conveyance unit 43 via the belts 83a to 83e.
f rotates. Therefore, the articles on the conveyor line 32 move in the horizontal direction and move to the branch line 33 side. When the transfer of the article is completed, the motor built-in roller 2 is rotated in the reverse direction. Here, when the motor built-in roller 2 is rotated in the reverse direction, the horizontal transport rollers 73a to 73 of the horizontal transport section 43 are rotated.
f stops rotating, and the horizontal conveyance unit 43 starts descending.

That is, when the roller 2 with built-in motor is rotated in the reverse direction, the projection 57 of the stopper plate 39 is moved to the stopper (projection) 6 as shown in FIGS.
Move in the direction away from 9. On the other hand, since the resistance of the cylindrical body 12 of the motor-equipped roller 2 is constantly applied by the cylindrical body-side resistance member 42, the central shafts 15, 16 having a low resistance are used.
The side rotates. Then, after the reverse rotation is started, the counting of the number of rotations is started.
Stop 5. That is, as shown in FIG.
The motor 45 is stopped when the protruding portion is at the upper position and the horizontal transport section 43 sinks as shown in FIG.

Since the transport device 35 of this embodiment incorporates a brushless motor in the roller 2 with a built-in motor, the number of rotations is counted and the motor 45 is moved to the position shown in FIG.
Is stopped, the motor 45 may be stopped by detecting the position of the origin by a mechanical means such as a limit switch or a stopper. However, adopting a method of counting the number of rotations and returning to the origin as in the present embodiment has an advantage that the traveling direction of the lateral conveyance unit 43 can be arbitrarily determined.
That is, the traveling direction of the lateral conveyance unit 43 is determined by the rotation direction of the motor built-in roller. On the other hand, as described above, since the elevation of the horizontal transport section 43 is determined only by the posture of the cam 38, the horizontal transport section 43 can be raised and lowered by rotating the roller 2 with any motor in any direction. It is.

However, if a measure for detecting the position of the origin by using a mechanical means such as a limit switch or a stopper is employed, the limit switch or the like may become an obstacle and it may be difficult to reverse the roller with a built-in motor. On the other hand, according to the measure of this embodiment, even if the center shafts 15 and 16 are reversely rotated as shown in FIG. There is nothing. Therefore, according to the transport device of the present embodiment, the lateral transport unit 43 can be moved in either the left or right direction, and the article can be discharged in either the left or right direction.

In the above-described embodiment, the configuration in which the speed reducer is built in as the motor built-in member is exemplified. However, the speed reducer is not essential, and a motor built-in member having no structure with the speed reducer is also applicable to the present invention.

[0100]

As described above, in the transfer device according to the first to fourth aspects, the main components are placed at the position surrounded by the endless long object, so that the outer shape is extremely small.
It can be installed at any position. Therefore, the transfer device of the present invention has an effect that it can be installed at an arbitrary position.

According to the third aspect of the present invention, the distance between the shafts of the other end member and the rotating member on the driving side changes, so that the tension of the endless long object can be kept constant even when the supporting member is moved up and down. There is an effect that can be done.

Further, in the transfer device according to the fourth aspect, since the rotation of the cylindrical body is stopped by the forced stopping means and the shaft is rotated, the structure is simple.

Also, the transfer device according to the fifth to tenth aspects has an extremely small outer shape and can be installed at any position. Therefore, the transfer device of the present invention has an effect that it can be installed at an arbitrary position.

Further, the roller conveyor device of the present invention has an effect that articles can be carried out or carried in from a conveyor line.
