Description

  The present invention relates to a transport device, and more particularly to a transport device that transports a workpiece having a predetermined axial direction with an outer peripheral surface being a cylindrical surface.

  There are processes for conveying a large number of parts (workpieces) in a single row in the manufacturing process and assembling process of various mechanical parts such as roller-shaped bearing components and cylindrical or cylindrical shapes. In such a transport process, a parts feeder is generally used.

  In the conveyance using the parts feeder, a wrinkle (striking) is generated in the work due to the work falling in the parts feeder bowl. In addition, the work is rubbed by vibration. Furthermore, when the parts feeder is used, the work is supported on the same surface, and the contact time becomes long and the contact surface is easily worn. Therefore, in recent years, there is an alignment conveyance device using a belt conveyor mechanism instead of such a feeder (Patent Documents 1 to 5).

And the bridge | bridging prevention means is arrange | positioned at the 1st belt conveyor mechanism. This bridge prevention means includes a rotation lever arranged on one taper wall of the narrowing guide, and the rotation of the rotation lever returns other workpieces that are not introduced into the alignment guide to the upstream, and is introduced into the alignment guide. Only the workpieces to be made are introduced into the alignment guide.

  In Patent Document 4, a guide A and a guide B arranged along the traveling direction of the conveyor belt are arranged on the conveyor belt in order to bring the workpiece (container) closer. At least one of the guide A and the guide B is provided with a plurality of rotatable rollers. By setting in this way, even when the workpiece is conveyed and the workpiece comes into contact with the roller, the roller naturally rotates in the traveling direction or the counter-traveling direction by the pressing force, and the bridge (bridge) ). In addition, by making the guide A swingable, it is possible to give movement to the container assembly and eliminate bridging (bridge) due to escape of the containers.

  FIG. 3 of Patent Document 5 discloses a configuration in which a plurality of side belts for guiding containers (workpieces) are arranged on one side of a conveyance path. In this case, the containers contacting the side belt are accelerated and aligned.

  FIG. 4 of Patent Document 5 discloses an arrangement in which a swinging guide that reciprocates in the transport direction and the counter-transport direction is arranged on one side of the transport path. This reciprocating movement of the swinging guide prevents the occurrence of bridging (bridge).

  FIG. 5 of Patent Document 5 discloses a belt having a moving side wall composed of a belt conveyor mechanism, in which the forward path of the belt is set to move in a direction opposite to the conveying direction. ing. Thus, by causing the belt on the moving side wall to travel in the anti-conveying direction, the occurrence of bridging (bridge) is prevented.

  However, the apparatus shown in FIGS. 3 to 5 of Patent Document 5 has problems as described in Paragraphs 0006 to 0008 of Patent Document 5. Therefore, this Patent Document 5 discloses an apparatus that solves these problems in FIGS. 1 and 2.

For this reason, in a state in which a workpiece such as a cylindrical body or a cylindrical body is arranged in a random posture and a random position, the wide conveyance path is arranged to be a narrow conveyance path (the axial center is a vertical axis). In the case of the apparatus described in Patent Document 1 to Patent Document 5, the workpiece that has fallen over is transported with a narrow width. It cannot be introduced into the path, and a bridge is generated at the entrance of the narrow conveyance path. Even if a bridge does not occur, the workpiece may remain on the conveyance path because it cannot be introduced into the conveyance path.

  In view of the above-described problems, the present invention can suppress wrinkling on a workpiece to be conveyed, and can convey a workpiece in a random posture to a discharge path in a single row without generating a bridge or the like. Providing equipment.

The conveying device of the present invention is a bearing component conveying device that conveys a bearing component having a predetermined axial direction whose outer peripheral surface is a cylindrical surface, wherein the multiple bearing components are arranged in a random posture and a random position.

The second sub belt is a flat belt that is disposed so as to be close to the belt and whose forward path travels downstream .

  In the conveyance device of the present invention, a plurality of workpieces arranged at random postures and random positions can be conveyed from the upstream side to the downstream side by a belt conveyor mechanism having a flat belt. When the workpiece is conveyed downstream by the belt conveyor mechanism, it can be guided to the downstream discharge path by the second guide means. Further, when the work guided to the downstream discharge path side comes into contact with the first guide means, the work is returned to the upstream side by the first guide means. For this reason, in the opening part of a downstream discharge path thru | or its vicinity, generation | occurrence | production of the bridge | bridging of a workpiece | work can be suppressed and the workpiece | work guided by the 2nd guide means can be introduce | transduced into a downstream discharge path. Moreover, since the workpiece | work arrange | positioned at a random attitude | position and a random position is conveyed, a workpiece | work is supported in the indefinite position on the workpiece | work mounting surface of the flat belt of a belt conveyor mechanism.

  The first guide means includes a first sub belt that is a flat belt that is disposed along the conveyance direction on one side downstream side of the belt conveyor mechanism, and whose forward path travels upstream.

Or by contacting the first sub-belt, the workpiece is conveyed upstream by the crosspiece member traveling in the direction opposite to the conveying direction (upstream) together with the first sub-belt. .

  The second guide means is arranged on the downstream side of the conveyor belt mechanism so as to approach the first sub belt of the first guide means from the upstream side toward the downstream side, and the forward belt travels downstream. It is preferable to have the 2nd subbelt which consists of these.

In this way, the workpiece that has entered between the crosspiece members is locked to the crosspiece member and conveyed (guided) upstream.

  It is preferable that the friction coefficient between the flat belt of the belt conveyor mechanism and the second sub belt and the workpiece is larger than the friction coefficient between the workpieces. By setting in this way, the workpiece is conveyed from the upstream side to the downstream side by the belt conveyor mechanism without so-called slip.

  The width dimension of the downstream discharge path is preferably 1.25 times to 1.75 times the shorter dimension of the outer diameter dimension and the axial length of the workpiece. By setting in this way, a workpiece in any posture can enter the downstream discharge path and be conveyed through the downstream discharge path.

  It is preferable to provide a work discharge port to the downstream discharge path between the downstream end portion of the first guide means and the downstream end portion of the second guide means. In addition, the opening size of the work discharge port can be adjusted. Furthermore, the inclination angle of the second guide means relative to the first guide means can be adjusted.

  The workpiece may be a bearing component, or another columnar or cylindrical part.

  According to the transport apparatus of the present invention, since the transport is performed by the belt conveyor mechanism, it is possible to suppress the generation of wrinkles due to hammering or vibration on the workpiece. Also, the work placing surface of the flat belt of the belt conveyor mechanism supports the work at an indefinite position, so that the work is not supported for a long time at the same part (same position), Wear can be suppressed.

  In particular, at the opening of the downstream discharge path or in the vicinity thereof, the occurrence of bridging of the work can be suppressed and the work can be carried out to the downstream discharge path in a state of being aligned in a single row, and the work remains in the transport path. Therefore, smooth conveyance is possible and the productivity is excellent. Moreover, the workpiece can be transported from a small amount to a large amount without being limited by the quantity.

  If the first guide means has a first sub belt in which a plurality of crosspiece members are arranged at a predetermined pitch along the conveyance direction, the crosspiece member can stably convey the work upstream. Bridge generation can be effectively prevented.

  If the second guide means has a second sub belt made of a flat belt that travels downstream, the workpiece conveyed downstream can be stably conveyed to the downstream discharge path.

  By setting the friction coefficient between the flat belt of the belt conveyor mechanism and the second sub-belt and the workpiece to be larger than the friction coefficient between the workpieces, the workpiece is conveyed from the upstream side to the downstream side by the belt conveyor mechanism without slipping. Is done.

  By setting the width dimension of the downstream discharge path from 1.25 times to 1.75 times the dimension of which the outer diameter dimension and the axial length of the workpiece are small, it is possible for a workpiece in any posture. It is possible to enter the downstream discharge path and transport the downstream discharge path.

  By providing the work discharge port to the downstream discharge path, the work can enter the downstream discharge path via the work discharge port.

  By making it possible to adjust the opening size of the work discharge port, the optimum size of the work discharge port when the work enters the downstream discharge path can be obtained.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  FIG. 1 shows a conveying apparatus according to the present invention, which conveys the workpiece W shown in FIGS. 2 to 4 and the like. The workpiece W has a predetermined dimension in the axial direction in which the outer peripheral surface has a cylindrical surface shape, and includes those described in FIGS. 2 (a) shows a cylindrical body, FIG. 2 (b) shows a cylindrical body, FIG. 3 (a) shows a solid cone, FIG. 3 (b) shows a hollow cone, 4 (a) shows a solid drum-shaped body, and (b) shows a hollow drum-shaped body. In addition, as such a workpiece | work W, it is the roller etc. which are bearing components, for example.

  As shown in FIG. 1, the transport device includes a belt conveyor mechanism 2 having a flat belt 1 that receives a large number of workpieces W in a random posture and a random position and transports them from the upstream side to the downstream side, and the belt conveyor mechanism 2. And a downstream discharge passage 3 that receives the workpieces W conveyed in the state of being arranged in a single row and conveys the workpieces in a single row further downstream.

  The belt conveyor mechanism 2 includes a driving roller (not shown), a driven roller (not shown), and a flat belt 1 wound around them. When the drive roller is driven, the forward path of the flat belt 1 travels in the arrow X direction. Further, side walls 5 and 6 are provided on both sides of the flat belt 1 so as to stand above the work placement surface of the forward flat belt. That is, the transport path 15 for transporting the workpiece W can be formed by the forward path of the flat belt 1 and the side walls 5 and 6.

  The downstream discharge path 3 includes a pair of guide walls 10 and 11 disposed so as to face each other at a predetermined parallel interval, and a bottom wall 12 that receives the workpiece W. Even if the conveying force in the downstream discharge path 3 is generated by the conveying force of the belt conveyor mechanism 2 (pressing force from the contacting workpiece W), the belt conveyor mechanism (a mechanism different from the belt conveyor mechanism 2). ). In addition, when generating with the pressing force from the workpiece | work W which is contacting, if the bottom wall 12 is made into the fixed state which does not move, the friction coefficient between the upper surface and the workpiece | work W can be made small as the bottom wall 12. Good.

  A first guide unit 21 and a second guide unit 22 are disposed on the downstream side of the conveyance path 15 of the belt conveyor mechanism 2. The first guiding means 21 is arranged along the conveying direction on one side of the downstream side of the conveying path 15, and the upstream side of the workpiece W conveyed to this side is the upstream side or downstream side. It imparts a resistance action. That is, the work W conveyed to the side is guided in the direction opposite to the conveyance direction (upstream side). Further, the second guide means 22 is disposed on the downstream side of the conveyance path 15 of the belt conveyor mechanism 2 so as to narrow the conveyance path 15 from the upstream side toward the downstream side, and on the downstream side of the conveyance path. It imparts a downstream conveying action or an upstream resistance action to the conveyed work. That is, the work W conveyed to the downstream side of the conveyance path 15 is guided to the downstream discharge path 3.

  The first guide means 21 includes a drive roller 23, a driven roller 24, and a first sub belt 25 made up of a flat belt wound around these. In this case, the forward path 25a of the first sub belt 25 extends on the extension line of the side wall 5 along the transport direction. For this reason, the outward path 25 a of the first sub belt 25 and the side wall on the side of the one side wall 5 on the downstream side of the transport path 15 are configured.

  Therefore, when the drive roller 23 is driven, the first sub belt 25 travels. In this case, the drive roller 23 and the driven roller 24 rotate in the direction of the arrow B1, so that the first sub belt 25 is driven. The forward path 25a travels in the direction of arrow C1, that is, from the downstream side, which is the direction opposite to the conveying direction, to the upstream side.

  A cross member 26 in the width direction (vertical direction) disposed at a predetermined pitch along the traveling direction is disposed on the first sub belt 25. For this reason, the workpiece W that is close to or in contact with the first sub belt 25 is conveyed upstream by the crosspiece member 26.

  As shown in FIG. 5, the arrangement pitch of the crosspiece members 26 and the conveyance direction interval P of the crosspiece members 26 are set larger than the outer diameter D and the axial length L of the workpiece W. Further, the vertical height H of the crosspiece member 26 is set to be smaller than the outer diameter D and the axial length L of the workpiece W. In this embodiment, the work W has a ratio (D / L) of an outer diameter dimension (diameter dimension) D and an axial length L of about 0.58 to 1.75.

  The second guide means 22 is disposed at the upper part on the downstream side of the conveyor belt mechanism 2 so as to approach the first sub belt 25 of the first guide means 21 from the upstream side toward the downstream side, and the forward path 32a. Has a second sub belt 32 composed of a flat belt traveling in the same direction (downstream) as the transport direction.

  In other words, the second guide means 22 includes a driving roller 30, a driven roller 31, and a second sub belt 32 wound around these. When the driving roller 30 is driven, the second sub belt 32 travels. In this case, the driving roller 30 and the driven roller 31 rotate in the direction of the arrow B2, and the forward path of the second sub belt 32. 32a travels in the direction of arrow C2, that is, from the upstream side to the downstream side in the transport direction.

  By the first guide means 21 and the second guide means 22, a downstream discharge path introducing portion 35 (introducing a right triangle in plan view) that becomes narrower sequentially from the upstream side to the downstream side on the downstream side of the conveyance path 15. Part) is formed. That is, the introduction portion 35 narrows from the other side wall 6 side toward the one side wall 5 side, and its discharge port (work discharge port) 35a is communicated with the downstream discharge path 3 as shown in FIG. The The width dimension T of the downstream discharge path 3 is set to be larger than the outer diameter dimension D and the axial length L of the work W. The width dimension T is set to the shorter dimension of the outer diameter dimension D and the axial length L of the workpiece, in this embodiment, from 1.25 times to 1.75 times the outer diameter dimension D of the workpiece W. preferable.

  In this embodiment, the friction coefficient between the flat belt 1 and the second sub belt 32 of the belt conveyor mechanism 2 and the workpiece W is set to be larger than the friction coefficient between the workpieces. When the friction coefficients between the flat belt 1 and the second sub belt 32 and the workpiece W are E1 and E2, and the friction coefficient E3 between the workpieces, E1 / E3 and E2 / E3 are each set to be twice or more, for example. .

  A workpiece transfer process by the transfer apparatus configured as described above will be described. In a state where the belt conveyor mechanism 2 is driven or stopped, a large number of workpieces W are supplied (placed) on the conveyor path 15 through the belt conveyor mechanism 2. In this case, it is not necessary to align the workpieces W, to make the workpieces W stand upright, or to lie down. That is, the conveyance path 15 of the belt conveyor mechanism 2 can receive a large number of workpieces W in a random posture and a random position arrangement.

  And if the belt conveyor mechanism 2 is not driven, it will drive. By this driving, the workpiece W is conveyed from the upstream side to the downstream side on the conveyance path 15 of the belt conveyor mechanism 2.

  If the work W comes in contact with the second belt 32 of the second guide means 22 as it is conveyed, the second belt 32 travels in the direction of the arrow C2, so that the contacted work W and the vicinity of the work W are near. The work W guides to the work discharge port 35a along the arrow C2 direction. If the workpiece W comes into contact with or is close to the first belt 25 of the first guide means 21, the crosspiece 26 is locked to the workpiece W because the first belt 32 travels in the direction of the arrow C1. Thus, the workpiece W is guided upstream in the direction of the arrow C1.

  For this reason, in the opening part of the downstream discharge path 3 (discharge port 35a of the conveyance path 35) or in the vicinity thereof, occurrence of a bridge of the work W is suppressed, and the work W guided by the second guide means 22 is downstream. It can be introduced into the side discharge path 3. Further, since the workpiece W arranged in a random posture and a random position is conveyed, the workpiece W is supported at an indefinite position on the workpiece placement surface of the flat belt 1 of the belt conveyor mechanism 2.

  In the transfer apparatus of the present invention, since the transfer is performed by the belt conveyor mechanism 2, it is possible to suppress the occurrence of wrinkles due to hammering or vibration on the workpiece W. Further, the work W is supported at an indefinite position on the work placing surface of the flat belt 1 of the belt conveyor mechanism 2, so that the work W is not supported for a long time at the same part (same position). The wear of the support surface can be suppressed.

  In particular, at the opening of the downstream discharge path 3 (discharge port 35a of the transport path 35) or in the vicinity thereof, the bridge of the workpiece W is suppressed, and the work W is transported to the downstream discharge path 3 in a state of being aligned in a single row. The transfer path 15 can be smoothly transferred without leaving the work W, and the productivity is excellent. Moreover, the workpiece W can be transported from a small amount to a large amount without being limited by the quantity.

  If the first guide means 21 has the first sub belt 25 in which a plurality of cross members 26 are arranged at a predetermined pitch along the transport direction, the work W is stably reversed by the cross members 26 in the transport direction. It can be conveyed in the direction (upstream), and the occurrence of bridges can be effectively prevented.

  If the second guide means 22 has the second sub belt 32 made of a flat belt whose forward path travels in the same conveying direction (downstream), the work W conveyed downstream is stably downstream. It can be conveyed to the side discharge path 3.

  By providing the work discharge port 35a to the downstream discharge path 3, the work W can enter the downstream discharge path 3 through the work discharge port 35a.

  By setting the friction coefficient between the flat belt 1 and the second sub belt 32 of the belt conveyor mechanism 2 and the workpiece W to be larger than the friction coefficient between the workpieces, the workpiece W is upstream in the belt conveyor mechanism 2 without so-called slipping. It is conveyed from the side to the downstream side.

  By setting the width T of the downstream discharge passage 3 from 1.25 times to 1.75 times the shorter dimension of the outer diameter D and the axial length L of the workpiece W, any posture Even the workpiece W can enter the downstream discharge path 3 and transport the downstream discharge path 3.

  In FIG. 7, the opening size of the work discharge port 35a can be adjusted. In this case, the second guide means 22 is configured to be movable. That is, if a belt conveyor mechanism constituted by the driving roller 30, the driven roller 31, the second sub belt 32, and the like is moved as shown by a virtual line by a driving mechanism (not shown), for example, the work discharge port The opening size of 35a can be changed (adjusted). The drive mechanism can be constituted by various mechanisms such as a cylinder mechanism, a ball nut mechanism, a linear guide mechanism, and a link mechanism.

  By making it possible to adjust the opening size of the workpiece discharge port 35a, the optimum size of the workpiece discharge port 35a when the workpiece W enters the downstream discharge path 3 can be obtained.

  Further, as shown in FIG. 8, the inclination angle θ of the second guide means 22 with respect to the first guide means 21 can be adjusted. In this case, the belt conveyor mechanism 2 composed of the driving roller 30, the driven roller 31, the second sub belt 32, and the like is not shown in the drawing with the work discharge port 35a as the center, as shown by the phantom line in FIG. What is necessary is just to make it rotate by a moving means. The rotating means can be composed of a pivot shaft on the workpiece discharge port 35a side and a drive mechanism such as a cylinder mechanism or a ball nut mechanism that swings the belt conveyor mechanism around the pivot shaft.

  As described above, by enabling the adjustment of the inclination angle θ of the second guide unit 22 with respect to the first guide unit 21, the feeding of the workpiece W to the workpiece discharge port 35a can be stabilized.

  As mentioned above, although it demonstrated per embodiment of this invention, this invention is not limited to the said embodiment, A various deformation | transformation is possible, for example, along the one side wall 5 of the belt conveyor mechanism 2 in embodiment. Although the first guide means 21 is disposed, the first guide means 21 may be disposed on the other side wall 6 side. Further, the workpiece W may be a workpiece having a predetermined dimension in the axial direction in which the outer peripheral surfaces of various machine parts and containers are cylindrical. Various materials such as metal, synthetic resin, glass, and earthenware can be adopted as the material constituting the workpiece W. Further, in the workpiece W of the embodiment (the workpiece shown in FIG. 5 and the like), the outer diameter dimension D is a cylindrical body smaller than the axial length L, but the outer diameter dimension D is larger than the axial length L. It may be a thing.

  The conveying speed of the belt conveyor mechanism 2 and the guiding speeds of the first and second guiding means 21 and 22 can be variously selected according to the type, size, material, and the like of the workpiece W. Further, as the first and second guide means 21 and 22, other conveyors such as a roller conveyor and a chain conveyor may be used without using a belt conveyor.
