Description

  The present invention relates to a transport device.

  Patent document 1 is disclosing the conventional conveying apparatus. This conveying apparatus can convey and convey a conveyed product. The conveyed product has a cylindrical main body and a cylindrical shaft portion that extends from both ends of the main body and has a smaller diameter than the main body. In addition, the transport device includes a pair of belt-like support members and a plurality of flat plate-like stop bodies that are rotatably attached to the respective support members.

  Each support member is arranged in parallel with the front surface and the back surface standing in the vertical direction. Moreover, each support member is arrange | positioned so that the upper end edge which opposes may incline and descend in one direction at the same angle from the same height. For this reason, when each shaft portion extending from both ends of the main body of the conveyed product is placed on the upper edge of each support member, the conveying device rolls and conveys the conveyed item from the inclined upper side to the inclined lower side. be able to.

  A set of stop bodies is attached to the same height position on the surface of each supporting member arranged in parallel in the vertical direction. In the transport device, a plurality of sets of stop bodies are continuously attached from an end portion on the inclined upper side to an end portion on the inclined lower side of each support member. Each stop is a flat plate whose height is gradually reduced in the direction from the inclined upper side to the inclined lower side of each support member in a state of being rotatably attached to the support member. Further, the stop body is bent upward at an intermediate position. For this reason, as for this stop body, the upper end edge and the lower end edge are bent. The upper end edge of the stop body is composed of a first upper end edge located on the inclined upper side of each support member from the bent part and a second upper end edge located on the inclined lower side.

  If the shaft portion of the conveyed product is not upward, the stop body rotates to the standby position where the first upper end edge is positioned below the upper end edge of the support member due to its own weight. In this state, the second upper edge protrudes above the upper edge of the support member. When the shaft portion of the conveyed product rolling from the inclined upper side to the inclined lower side of each support member comes into contact with the second upper end edge via the first upper end edge, the second upper end edge of each stop member is caused by the load of the conveyed item. It rotates to the stop position which becomes a position which overlaps with the upper end edge of a support member. In this state, the first upper edge of the stopping body protrudes above the upper edge of the support member. That is, since the first upper end edge is located on the inclined upper side of the support member, the shaft portion of the other transported object that has rotated to the inclined upper side comes into contact with the rear end portion of the stop body and is stopped. . That is, the stop body rotated to the stop position prevents the conveyed product from rolling toward the lower tilt side.

  As described above, in this transport device, the transported object sequentially rolls to the stop body on the inclined lower side by repeatedly rotating the stop body between the standby position and the stop position, and the inclined upper end of each support member. It can be conveyed from the end on the part side to the end on the inclined lower side.

JP 2006-143376 A

  However, in the transport device of Patent Document 1, when the shaft of the transported object disappears above the second upper end edge of the stop body and the stop body rotates by its own weight from the stop position to the standby position, the rear end of the stop body The conveyed product that has been stopped by contacting the portion is pushed back to the upper inclined side of the support member. In other words, since the stop body rotates from the stop position to the standby position against the load of the transported object that has been stopped, if this push-back distance is large, the stop body can rotate well from the stop position to the standby position. May not move. If the stop body does not rotate from the stop position to the standby position, the conveyed product cannot be conveyed.

  This invention is made | formed in view of the said conventional situation, Comprising: It is set as the problem which should be solved to provide the conveying apparatus which can convey a conveyed product favorably.

The transport device of the present invention is a transport device that rolls and transports a rod-shaped transport object,
A plurality of support members whose upper edges extend downwardly and incline in one direction at the same angle from the same height, and a plurality of support members are arranged in series in the direction in which the support members extend between the adjacent support members. And a stop body rotatably supported between a standby position and a stop position on a rotation shaft orthogonal to each of the support members,
This stop is
A first upper surface that extends parallel to the upper end edge of the support member and a lower inclined side of the support member on the first upper surface at the standby position in which the transported object is not placed and rotated by its own weight. A second upper surface which is bent and continuous at the lower end edge positioned and expands so that an angle formed with the first upper surface becomes an obtuse angle; and an upper end edge positioned on the inclined upper side of the support member on the first upper surface When the conveyed product rolls from the first upper surface to the second upper surface, the second upper surface is rotated by the load of the conveyed item and the second upper surface is supported by the support surface. Expanding in parallel to the upper edge of the member, the hanging surface is the stop position protruding from the upper edge of the support member,
The rotation axis is
It is located above the center height from the said 1st upper surface to the lower end of the said drooping surface, It is characterized by the above-mentioned.

  In this transport device, the rotation shaft that pivotally supports the stop body is positioned above the center height from the first upper surface to the lower end of the hanging surface. Thereby, when the stop body is rotated from the stop position to the standby position, the distance by which the hanging surface of the stop body moves to the inclined upper side of the support member can be shortened.

  That is, as shown in FIG. 7, from the rotation axis A2 to the stop body in the stop body S2 in which the rotation axis A2 is located at a position far from the first upper surface (lower than the central height from the first upper surface to the lower end of the hanging surface). The rotation axis A1 is placed at a position closer to the first upper surface (above the center height from the first upper surface to the lower end of the lower surface) than the distance L2 to the intersection C on the extension line between the first upper surface and the vertical surface. The distance L1 from the rotational axis A1 to the intersection C in the positioned stop body S1 can be shortened. For this reason, when the rotation shaft is positioned close to the first upper surface, the distance by which the hanging surface, which is the rear end of the stop body, moves to the inclined upper side of the support member when the stop body rotates from the stop position to the standby position. Becomes shorter. That is, it is possible to shorten the distance for returning the transported object that is stopped by contacting the hanging surface when the stop body is rotated from the stop position to the standby position. For this reason, the stop body can be smoothly rotated from the stop position to the standby position.

  Therefore, the transport apparatus of the present invention can transport the transported article satisfactorily.

As shown in FIG. 1, the transport device of the embodiment can transport a transported object 10 having a rod shape and a circular cross section perpendicular to the central axis, for example, a shock absorber without a power source. it can. This transport device includes a plurality of support members 20 whose upper end edges are inclined downward in parallel and extend in one direction, and a plurality of support members 20 arranged in series in the direction in which the support members 20 extend between adjacent support members 20. The stop body 30 is provided.

  Each support member 20 includes a narrow upper plate portion 21 extending in a straight line and left and right side plate portions 22 extending downward from the left and right of the upper plate portion 21. The two support members 20 in which the upper surface of the upper plate portion 21 is arranged at the same height and parallel to each other are suspended from the left and right plate portions 22 that are located on the inner side of the respective support members 20 and face each other. The plate portion 41 and the bottom plate portion 42 that connects the lower end portions of the hanging plate portions 41 are integrally formed to constitute the frame member 40. The frame member 40 is formed by bending a metal plate. Each support member 20 has a support hole 23 that supports one of both end portions of the rotation shaft 37 to be described later over the upper part of one left and right side plate portion 22 located inside from the inner portion of the upper plate portion 21. Notched and formed.

  In the transport device, two frame members 40 having the same length are mounted on a flat base plate 50 in parallel with a predetermined interval. That is, the bottom plate portion 42 of the frame member 40 is fixed to the upper surface of the base plate 50. For this reason, the upper surface (upper edge of the support member 20) of the upper plate portion 21 of each support member 20 extends at a certain height with respect to the bottom plate portion 42. As shown in FIGS. 1 to 5, the base plate 50 includes a stopper plate 51 that rises from an edge portion where one end portions of the two frame members 40 are located. The base plate 50 is fixed with an inclination so that the stopper plate 51 is located on the lower end side and the angle α with respect to the horizontal plane is about 5 degrees. Thereby, the upper surface (upper end edge of the support member 20) of the upper plate portion 21 of each support member 20 is arranged to extend downwardly in one direction in parallel at the same angle from the same height.

  Each stop body 30 is made of resin. As shown in FIG. 6, these stop bodies 30 are hollow and open downward, and include a first upper surface 31, a second upper surface 32, a rear hanging lower surface 33, a front hanging lower surface 34, and a left and right hanging lower surface 35. have. As shown in FIG. 2, the first upper surface 31 is parallel to the upper end edge of the support member 20 at the same height as the upper end edge of the support member 20 at the standby position where the transport body 10 is not placed on the stop body 30. It has spread to. As shown in FIG. 1, the first upper surface 31 has a width that is slightly narrower than the distance between the left and right side plate portions 22 of the two adjacent support members 20 that constitute one frame member 40. The support member 20 has a rectangular shape in which the extending direction is longer than the lateral width. As described above, the first upper surface 31 is formed by a plane extending between the support members 20.

  The second upper surface 32 is bent and continuous at the lower end edge located on the inclined lower side of the support member 20 of the first upper surface 31, and as shown in FIG. It spreads to an obtuse angle of 160 degrees. As shown in FIG. 1, the second upper surface 32 has the same width as the first upper surface 31 and has a rectangular shape in which the direction in which the support member 20 extends is shorter than the lateral width. The second upper surface 32 is also formed by a plane extending between the support members 20.

  As shown in FIG. 6, the rear lower surface 33 is a lower lower surface that continuously hangs down from the upper end edge located on the inclined upper side of the support member 20 of the first upper surface 31. A boundary portion 36 between the first upper surface 31 and the trailing lower surface 33 is formed as an R surface. The trailing bottom surface 33 has the same width as the first top surface 31. That is, the rear lower surface 33 has a rectangular shape that has a width slightly smaller than the interval between the opposing left and right side plate portions 22 of the two adjacent support members 20 and whose vertical direction is shorter than the lateral width. The rear hanging surface 33 is also formed by a plane extending between the support members 20.

  The front drooping lower surface 34 hangs continuously from the lower edge of the second upper surface 32 located on the inclined lower side of the support member 20. The front drooping lower surface 34 has the same width as the second upper surface 32. The front and lower bottom surface 34 has a rectangular shape whose vertical direction is shorter than the lateral width. The front hanging surface 34 is also formed by a plane extending between the support members 20.

  The left and right hanging surfaces 35 are continuous with the left and right edge portions of the first upper surface 31, the second upper surface 32, the rear hanging surface 33, and the front hanging surface 34. The left and right hanging surfaces 35 have the same vertical height as the trailing and lower hanging surfaces 33 and 34, and the lower end edges of the left and right hanging surfaces 35 have lower end edges parallel to the first upper surface 31 and the second upper surface 32. And bent.

  Each stop 30 is below the boundary between the first top surface 31 and the second top surface 32, is parallel to the first top surface 31, and extends downwardly away from the first top surface 31 by a set distance X. The center of the rotating shaft 37 is located at the intersection A between the virtual parallel line P1 and the second virtual parallel line P2 that is parallel to the second upper surface 32 and extends downward from the second upper surface 32 by a set distance X. Yes. The rotating shaft 37 is located above the center height H from the first upper surface 31 to the lower end of the trailing lower surface 33. Further, the rotary shaft 37 has a front lower surface 34 (an end portion on the inclined lower side of the support member 20 of the second upper surface 32) than the rear lower surface 33 (an end portion on the inclined upper side of the support member 20 of the first upper surface 31). It is provided in the position near.

  The rotating shaft 37 penetrates the left and right hanging surfaces 35, and both end portions protrude in the left and right direction of each stop body 30. As shown in FIG. 1, both end portions of the rotation shaft 37 are supported by support holes 23 formed in two adjacent support members 20 constituting one frame member 40.

  As shown in FIG. 2, the respective stop bodies 30 are arranged in series in the direction in which the support member 20 extends at an interval. The bottom plate portion 42 of the frame member 40 is such that the first upper surface 31 is substantially the same height as the upper end edge of the support member 20 at the standby position where the stop 30 does not place the transported object 10 and is rotated by its own weight. The lower end edge of the rear lower surface 33 of the stop body 30 and the lower end edge of the left and right lower surface 35 positioned below the first upper surface 31 are in contact with each other so as to spread in parallel, thereby restricting the rotation of the stop body 30. Further, as shown in FIG. 3, the bottom plate portion 42 of the frame member 40 has a first position at a stop position where the conveyed product 10 rolls from the first upper surface 31 to the second upper surface 32 and is rotated by the load of the conveyed product 10. 2 The lower end edge of the front hanging surface 34 of the stop body 30 and the lower end edge of the left and right hanging surface 35 positioned below the second upper surface 32 so that the upper surface 32 extends in parallel at substantially the same height as the upper end edge of the support member 20. It contacts and regulates the rotation of the stop body 30. As described above, the bottom plate portion 42 of the frame member 40 is a restricting portion that restricts the stop body 30 to rotate between the standby position and the stop position.

  In the transport apparatus having such a configuration, the transported objects 10 are loaded on the two support members 20 of the two frame members 40 one by one from the inclined upper side with a feeding interval. Then, each conveyed product 10 rolls to the inclined lower side of the support member 20. The first conveyed product 10 comes into contact with a stopper plate 51 located at the end of the support member 20 on the inclined lower side and stops. That is, the first transport object 10 rolls from the first upper surface 31 of the first stop body 30 on the inclined lower side of the support member 20 to the second upper surface 32, and the first stop body is loaded by the load of the transport object 10. 30 is rotated, the second upper surface 32 expands in parallel at substantially the same height as the upper end edge of the support member 20, and the trailing lower surface 33 becomes a stop position protruding from the upper end edge of the support member 20. As a result, the second conveyed product 10 comes into contact with the rear lower surface 33 of the first stop 30 and the rolling is stopped. In this state, the second conveyed product 10 rolls on the second upper surface 32 of the second stop body 30, and the second stop body 30 is also rotated to the stop position. In this way, in the transport apparatus, the transported object 10 rolls on the second upper surface 32 of each stop body 30, and the other transported object 10 that has rolled to the inclined upper side rolls to the inclined lower side. Can be stopped.

  At this time, since the stop body 30 is made of resin, even if the conveyed product 10 comes into contact with the trailing lower surface 33, the conveyed product 10 is hardly damaged. Moreover, since the trailing lower surface 33 has a width slightly narrower than the interval between the opposing left and right side plate portions 22 of two adjacent support members 20 and is formed by a plane extending between the support members 20, The object 10 abuts on a straight line and can be stopped without tilting.

  When the first transported object 10 is taken out from the transport device, the first stop 30 is rotated to the standby position by its own weight as shown in FIG. 4, and the second transported object 10 is moved to the second stop 30. Roll from the second upper surface 32 to the first upper surface 31 of the first stop 30. As shown in FIG. 5, the second transported object 10 that has rolled to the first upper surface 31 of the first stop body 30 further rolls to the second upper surface 32, so that the first stop body 30 is at the stop position. To turn. In this way, each stop body 30 is rotated from the stop position to the standby position, and the transported object 10 that has been rolled from the inclined upper side is placed, and is again rotated to the stop position. In this way, each stop body 30 positioned on the inclined upper side gradually rotates, so that the conveyed product 10 is conveyed from the inclined upper side of the support member 20 to the inclined lower side while being stopped for each stop body 30. be able to. That is, this conveyance apparatus can convey the conveyed product 10 one by one without a power source from the inclination upper part side of the support member 20 to the inclination lower part side.

  In this conveying apparatus, as shown in FIG. 6, the rotating shaft 37 is positioned above the center height from the first upper surface 31 to the lower end of the hanging surface, so that the stop body 30 rotates from the stop position to the standby position. In doing so, the distance that the trailing lower surface 33 of the stop body 30 moves to the inclined upper side of the support member 20 is short. For this reason, when the stop body 30 rotates from the stop position to the standby position, the distance to push back the conveyed product 10 that is in contact with the trailing lower surface 33 and is stopped to the inclined upper side can be shortened. Therefore, the stop body 30 can be smoothly rotated from the stop position to the standby position.

  Therefore, the conveyance apparatus of an Example can convey the conveyed product 10 favorably.

  Further, in this transport device, a boundary portion 36 between the first upper surface 31 and the trailing lower surface 33 of the stop body 30 is formed as an R surface. For this reason, when the stop body 30 rotates from the stop position to the standby position, the distance to push the conveyed object 10 back to the inclined upper side is shortened, and the conveyed object 10 is a boundary between the first upper surface 31 and the trailing lower surface 33. The part 36 is not caught and can be smoothly rotated.

  Moreover, in this conveying apparatus, since the rotating shaft 37 is located in the intersection A of the 1st virtual parallel line P1 and the 2nd virtual parallel line P2, the 1st upper surface 31 in the standby position of the stop body 30, and a stop position The height of the second upper surface 32 can be made equal. For this reason, the conveyed product 10 can be smoothly rolled from the 2nd upper surface 32 of the stop body 30 located in the inclination upper part side of the support member 20 to the 1st upper surface 31 of the stop body 30 located in the inclination lower part side.

  Further, in this transport apparatus, the rotating shaft 37 has a front lower surface 34 (an inclined lower portion of the support member 20 on the second upper surface 32) than the rear lower surface 33 (an end portion on the inclined upper side of the support member 20 on the first upper surface 31). Near the end). For this reason, the stopping body 30 can rotate to the standby position where the first upper surface 31 spreads in parallel at the same height as the upper end edge of the support member 20 by its own weight.

  Moreover, in this conveyance apparatus, since the stop body 30 is formed with resin and the conveyed product 10 rolls on the first upper surface 31 and the second upper surface 32, when the conveyed product 10 rolls and is conveyed. Hard to get scratched.
