Description

  The present invention relates to a work shooter configured to once receive a workpiece flow and then cause the received workpiece to flow again.

  For example, when mass-producing various parts made of metal materials, etc., an unloading path for unloading the processed parts is provided for a machine that performs processing such as processing and cleaning of these parts. The parts are collected in a collection box or the like. In the carry-out path, the parts may be carried out together with a cleaning liquid for washing the processed parts. Also, the carry-out path may be called a work shooter.

  In order to shorten the cycle time for processing parts in the machine, the carry-out path is mostly configured so that the parts flow continuously. That is, generally, in the carry-out path of the machine, the flow of the parts carried out from the machine is not controlled.

  An example of a work shooter that controls the flow of parts carried out of a machine is described in Patent Document 1. In Patent Document 1, when configuring a part of the component automatic circulation supply device, an inclined chute is connected to the downstream side of the flow of the bar-shaped component in the conveyor, and the flow-down state of the rod-shaped component is set downstream of the inclined chute. It is practiced to provide a separating drum that can be rotated forward and backward.

  By the way, parts made of metal materials, etc. are precision parts that want to avoid fine scratches of several microns to several tens of microns on the surface, such as components that control the flow of fluid in hydraulic circuits, etc. There is also. When carrying out these precise parts, it is difficult to prevent fine scratches on the surface of the parts unless special measures are taken in the carry-out path through which the parts are carried out from the machine.

  Further, in the work shooter such as the separation drum described in Patent Document 1 and the sheet member described in Patent Document 2, no contrivance has been made to prevent the bar-shaped part or article from being damaged. In order to prevent fine scratches from entering a workpiece such as a part, how to reduce the impact applied to the workpiece is a problem.

  The present invention has been made in view of such problems, and has been obtained in an attempt to provide a work shooter that can prevent fine scratches from entering a work when the work is caused to flow down.

One aspect of the present invention is a work shooter configured to once flow down a workpiece and then flow down the received workpiece again,
An initial position in which the opening side of the concave receiving surface is directed upward so as to receive the flow of the workpiece, and the concave shape so that the received workpiece flows down again. A pivot receiving member that is pivotable to a pivot position in which the opening side of the receiving surface is directed sideways or downward;
A rotation mechanism for repeatedly rotating the rotation receiving member between the initial position and the rotation position;
A flow-down member attached to the rotation receiving member, for further flowing down the work flowing down from the concave receiving surface,
The flow-down member includes the rotation receiving member and the workpiece collection surface on which the workpiece is collected or the workpiece when the rotation receiving member is rotated from the initial position to the rotation position by the rotation mechanism. The work shooter is capable of forming a curved flow surface between another workpiece placed on the collection surface.

  The work shooter is configured using a rotation receiving member, a rotation mechanism, and a flow-down member. In particular, by attaching a flow-down member to the rotation receiving member and devising the shape of the flow-down member, the work received on the concave receiving surface of the rotation receiving member was placed on the work collection surface or the work collection surface. When it is made to flow down onto another workpiece, it makes it difficult for impact to be applied to the workpiece.

When the work flowing down to the rotation receiving member is caused to flow down from the rotation receiving member to the work collection surface, the following operation is performed in the work shooter.
The work flowing down to the rotation receiving member is temporarily received by the concave receiving surface of the rotation receiving member at the initial position. As a result, the momentum of the workpiece flowing down to the rotation receiving member is temporarily stopped. Next, the rotation receiving member in which the workpiece is disposed on the concave receiving surface rotates from the initial position to the rotation position.

  At this time, the flow-down member forms a curved flow surface between the concave receiving surface and the workpiece collection surface. The curved flow surface is formed as a surface in which the portion located on the upstream side has a steep gradient that is nearly perpendicular to the horizontal direction, and the gradient becomes gentler toward the downstream side.

  When the work flows down from the concave receiving surface of the pivot receiving member to the flow lower surface of the flow-down member, the work has a downward flow at the beginning of the flow, but the momentum is weakened at the end of the flow, and the downward flow In a state where the pressure is weakened, the workpiece flows down onto the workpiece collection surface or another workpiece placed on the workpiece collection surface. Thereby, when a workpiece | work is collect | recovered, an impact can be made hard to apply to a workpiece | work.

  Further, when the rotation receiving member rotates to the rotation position, the height from the work collection surface to the workpiece on the concave receiving surface of the rotation receiving member is lowered. In other words, the potential energy when the work flows down decreases. The workpiece on the concave receiving surface flows down onto the workpiece collection surface or another workpiece placed on the workpiece collection surface via the flow surface of the flow-down member in a state where the height from the workpiece collection surface is low. can do. This also makes it difficult for an impact to be applied to the workpiece when the workpiece is collected.

  Therefore, according to the work shooter, when the work flows down, it is possible to prevent the work from being finely scratched.

“Upward” for “initial position” includes diagonally upward. In addition, “downward” in the “rotation position” includes diagonally downward.
Further, the “curved bottom surface” is formed either when the rotation receiving member rotates from the initial position to the rotation position or in the process of rotating the rotation receiving member from the initial position to the rotation position. May be.

<Embodiment 1>
As shown in FIGS. 1 to 5, the work shooter 1 according to the present embodiment is configured to control the flow of the work 8, and once the flow of the work 8 is received, the received work 8 is made to flow again. ing. The work shooter 1 includes a rotation receiving member 2, a rotation mechanism 3, and a flow-down member 4.

  The rotation receiving member 2 has a concave receiving surface 21 for receiving the flow of the work 8. As shown in FIG. 2, the rotation receiving member 2 has an initial position 201 in which the opening side 211 of the concave receiving surface 21 is directed upward so as to receive the flow of the work 8, and as shown in FIGS. 3 and 4. Then, the opening side 211 of the concave receiving surface 21 can be turned to a turning position 202 directed downward so that the received work 8 flows down again. The rotation mechanism 3 is configured to repeatedly rotate the rotation receiving member 2 between an initial position 201 and a rotation position 202.

  As shown in FIGS. 2 and 5, the flow-down member 4 is attached to the downstream end 22 in the flow-down direction of the work 8 in the rotation receiving member 2, and further flows the work 8 flowing down from the concave receiving surface 21. It is what makes it flow down. As shown in FIGS. 3 and 4, the flow-down member 4 is connected to the downstream end of the rotation receiving member 2 when the rotation receiving member 2 is rotated from the initial position 201 to the rotation position 202 by the rotation mechanism 3. A curved flow surface 41 can be formed between the portion 22 and the workpiece collection surface 61 from which the workpiece 8 is collected or another workpiece 8A placed on the workpiece collection surface 61.

  Here, “another work 8A” refers to a work that has already been collected on the work collection surface 61 by the work shooter 1. The other work 8A is the work 8 collected on the work collecting surface 61 by the work shooter 1 before the previous time.

  2 to 4 show a state in which another workpiece 8A is not placed on the workpiece collection surface 61. FIG. 3 and 4, the flow-down member 4 may be disposed on another work 8 </ b> A placed on the work collection surface 61.

  In each figure of this embodiment, the state in which the work 8 flows down is indicated by an arrow F, and the state in which the rotation receiving member 2 rotates is indicated by an arrow R. FIG. 3 shows a state in which the rotation receiving member 2 is at an intermediate position 203 in the middle of rotating from the initial position 201 to the rotation position 202. FIG. 4 shows not only the state in which the rotation receiving member 2 is in the rotation position 202 but also the state in the intermediate position 203.

Hereinafter, the work shooter 1 of this embodiment will be described in detail.
(Work 8)
As shown in FIG. 1, the workpiece 8 of this embodiment is a metal part made of a metal material, and has an outer peripheral surface having a circular cross section. Since the workpiece 8 has a cylindrical shape provided with a groove or the like, it can roll around its central axis. The workpiece 8 is a spool of a spool valve used in the hydraulic circuit of the automatic transmission. The spool is used to open and close an oil path in the hydraulic circuit. The spool is formed in a cylindrical shape having one or a plurality of grooves.

  Although not shown, the outer peripheral surface of the spool slides with respect to the inner peripheral surface of the spool hole of the valve body. There is a gap of several microns to several tens of microns between the outer peripheral surface of the spool and the inner peripheral surface of the spool hole. In order to maintain the formation state of the gap of about several microns to several tens of microns, it is preferable that the outer peripheral surface of the spool has no fine scratch of about several microns to several tens of microns. Therefore, the work shooter 1 of the present embodiment aims to prevent fine scratches from occurring on the outer peripheral surface of the spool as the work 8.

(Work carry-out path 51)
As shown in FIG. 1, the work shooter 1 is disposed and used in a work carry-out path 51 in a machine 5 that performs processing such as cutting and polishing on the work 8. The workpiece carry-out path 51 is connected to the transfer conveyor 52 for transferring the workpiece 8 from the machine 5 and the fixed chute that is connected to the transfer conveyor 52 and flows down to the rotation receiving member 2 of the workpiece shooter 1. 53 are arranged.

  The fixed chute 53 is disposed with a predetermined inclination angle so that the work 8 received from the transfer conveyor 52 flows down. The rotation receiving member 2 of the work shooter 1 is disposed below the downstream end of the fixed chute 53. When the rotation receiving member 2 is at the initial position 201, the work 8 flowing down from the fixed chute 53 is received by the concave receiving surface 21 of the rotation receiving member 2. The flow surface 531 of the fixed chute 53 is formed of a resin member in order to prevent the outer peripheral surface of the work 8 from being damaged.

  As shown in FIG. 1, the workpieces 8 are unloaded one by one from the machine 5 to the workpiece unloading path 51. Then, the workpieces 8 are independently carried out one by one onto the workpiece collection surface 61 or another workpiece 8 placed on the workpiece collection surface 61 via the transfer conveyor 52, the fixed chute 53 and the workpiece shooter 1. Is done. By individually unloading the workpieces 8 one by one, it is avoided that the workpieces 8 flowing down contact each other.

(Support base 30)
As shown in FIG. 1, the work shooter 1 includes a support base 30 to which the rotation mechanism 3 is attached and which supports the rotation of the rotation receiving member 2. The rotation receiving member 2 is provided with a rotation shaft portion 23 for enabling the rotation receiving member 2 to rotate with respect to the support base 30. The rotation shaft portion 23 is disposed at the upstream end of the rotation receiving member 2 that is located on the opposite side to the side on which the flow-down member 4 is attached.

(Rotation receiving member 2)
As shown in FIG. 2, the rotation receiving member 2 includes a semi-cylindrical tube main body 24 and a pair of side plates 25 attached to both ends of the tube main body 24. On the inner peripheral surface of the cylinder main body 24, a rubber or resin impact relaxation sheet 26 for reducing the impact applied to the workpiece 8 is disposed. The concave receiving surface 21 is formed in a circular arc shape as an inner peripheral surface of the impact relaxation sheet 26. The length direction of the rotation receiving member 2 (the axial direction of the semi-cylindrical cylindrical main body 24) is oriented in the horizontal direction.

  As shown in FIG. 2, when the rotation receiving member 2 is in the initial position 201, the opening side 211 of the concave receiving surface 21 is directed obliquely upward, and the flow of the work 8 is stopped by the concave receiving surface 21. Is possible. When the rotation receiving member 2 is at the initial position 201, the downstream end 22 of the rotation receiving member 2 to which the flow-down member 4 is attached is disposed in the lateral direction of the rotation shaft portion 23. The rotation receiving member 2 rotates in the rotation direction in which the downstream end 22 moves relatively downward with respect to the rotation shaft portion 23, and changes from the initial position 201 to the rotation position 202.

  The rotation receiving member 2 of the present embodiment rotates more than a half turn from the initial position 201 and moves to the rotation position 202. That is, the rotation receiving member 2 is further rotated from the position where the workpiece 8 is moved down by about 90 ° from the initial position 201. By increasing the rotation amount of the rotation receiving member 2, the work 8 can flow smoothly from the flow-down member 4 to the work collection surface 61.

(Rotating mechanism 3)
As shown in FIGS. 1 and 5, the rotation mechanism 3 includes a rotation drive source 31 for driving the rotation receiving member 2 to rotate. The rotation drive source 31 is composed of a rotary cylinder that reciprocates and rotates the output unit by a predetermined rotation angle. The output portion of the rotation drive source 31 is connected to the rotation shaft portion 23 of the rotation receiving member 2. The rotation receiving member 2 reciprocally rotates between the initial position 201 and the rotation position 202 in response to the driving force from the rotation drive source 31.

(Control device 10)
As shown in FIG. 1, the work shooter 1 includes a control device 10 that controls the operation of the rotation drive source 31. The control device 10 is configured to synchronize the timing at which the rotation receiving member 2 is rotated by the rotation drive source 31 with the timing at which the workpiece 8 is unloaded to the workpiece unloading path 51 in the machine 5. The control device 10 can be configured in a control device that controls the operation of the machine 5. The control device 10 may be configured separately from the control device that controls the operation of the machine 5.

  The workpiece 8 is unloaded from the machine 5 to the workpiece unloading path 51 at predetermined time intervals. The rotation receiving member 2 has an initial position 201 and a rotation position 202 at a time interval corresponding to a time interval at which the work 8 is carried out to the work carry-out path 51 by the rotation drive source 31 under the control of the control device 10. Rotate between. Further, the rotation drive source 31 moves the rotation receiving member 2 from the initial position 201 to the rotation position 202 every time one workpiece 8 is received by the concave receiving surface 21 of the rotation receiving member 2 from the work carry-out path 51. It is configured to rotate. Accordingly, the workpieces 8 are periodically carried out one by one from the workpiece carry-out path 51 to the rotation receiving member 2, and one workpiece 8 is transferred from the rotation receiving member 2 to the workpiece collection surface 61 via the flow-down member 4. It flows down periodically.

(Flowing member 4)
The flow-down member 4 is formed of a flexible sheet member. The sheet member of this embodiment is made of a rubber material that has flexibility and can be easily bent into a curved surface. As shown in FIG. 3, the flow-down member 4 is placed on the workpiece collection surface 61 or the workpiece collection surface 61 when the rotation receiving member 2 is rotated from the initial position 201 to the rotation position 202 by the rotation mechanism 3. The curved lower surface 41 is formed by slidingly contacting and bending another workpiece 8A.

  As shown in FIG. 2, the flow-down member 4 is composed of a sheet member, so that when the rotation receiving member 2 is at the initial position 201, the flow-down member 4 is lowered from the downstream end 22 of the rotation receiving member 2 by gravity. It is in the state of hanging down. As shown in FIG. 3, the flow-down member 4 forms a flow surface 41 that is bent concavely toward the upper side in the process in which the rotation receiving member 2 is rotated from the initial position 201 to the rotation position 202.

  As shown in FIG. 4, the flow-down member 4 of the present embodiment forms a workpiece collection surface 61 that forms a workpiece collection surface 61 when the rotation receiving member 2 is rotated from the initial position 201 to the rotation position 202 by the rotation mechanism 3. A curved flow surface 41 is formed in the box 6 so as to be drawn out of the work collection box 6. Thereby, the work 8 that has flowed down from the concave receiving surface 21 of the rotation receiving member 2 to the flow lower surface 41 of the flow down member 4 is placed on the work collection surface 61 or the workpiece collection surface 61 from above the flow lower surface 41. It is possible to smoothly flow down on the workpiece 8A.

  When the pivot receiving member 2 is pivoted to the pivot position 202, the end of the flow-down member 4 remains in the work collection box 6, so that the pivot receiving member 2 returns to the initial position 201. When it does, the flow-down member 4 can also return to the original drooping state.

  The work shooter 1 according to the present embodiment is configured such that when the rotation receiving member 2 is rotated from the initial position 201 to the rotation position 202 by the rotation mechanism 3, the workpiece 8 rolls on the concave receiving surface 21 of the rotation receiving member 2. However, the work 8 flows down to the flow lower surface 41 of the flow down member 4, and the work 8 rolls on the flow lower surface 41 and flows down to the work collection surface 61.

(Work collection surface 61)
The workpiece collection surface 61 is formed as a bottom upper surface of the workpiece collection box 6 for collecting a plurality of workpieces 8 that have been processed. The workpiece collection box 6 is placed on the table 54. When an appropriate number of workpieces 8 are collected in the workpiece collection box 6, a plurality of processed workpieces 8 are taken out from the workpiece collection box 6.

  In addition, below the rotation receiving member 2 of the work shooter 1, you may arrange | position the conveyor etc. which move the workpiece | work 8, or the chute | shoot which flows down a workpiece | work to another position. In this case, the workpiece collection surface 61 is the upper surface of the conveyor or chute.

(Export method and effect)
Next, a method for unloading the processed workpiece 8 from the workpiece unloading path 51 of the machine 5 to the workpiece collection surface 61 using the workpiece shooter 1 of the present embodiment, and the effects of the workpiece shooter 1 will be described.
As shown in FIG. 1, in the transfer conveyor 52, the workpiece 8 is transferred in a state where the center axis thereof is directed in the transfer direction of the transfer conveyor 52. Then, the workpiece 8 is guided by the guide portion 521 provided on the transfer conveyor 52 and flows down to the fixed chute 53. The fixed chute 53 is arranged so as to intersect the transfer conveyor 52. The work 8 that flows down to the rotation receiving member 2 in the fixed chute 53 can roll around its central axis.

  As shown in FIG. 2, when the work 8 flows down the fixed chute 53, the rotation receiving member 2 is at the initial position 201. Then, the workpiece 8 that has entered the concave receiving surface 21 of the rotation receiving member 2 rolls along the inner peripheral surface of the concave receiving surface 21 and is then held (received) by the concave receiving surface 21. Thus, the flow of the work 8 is temporarily received by the concave receiving surface 21 of the rotation receiving member 2 at the initial position 201. As a result, the momentum of the work 8 flowing down to the rotation receiving member 2 is temporarily stopped.

  Next, after the workpiece 8 is received by the rotation receiving member 2, as shown in FIGS. 3 and 4, the rotation receiving member 2 is moved to the initial position 201 around the rotation shaft portion 23 by the rotation mechanism 3. To the rotation position 202. The rotation receiving member 2 rotates from the initial position 201 to the rotation position 202 when a predetermined time has elapsed from the time when the workpiece 8 is unloaded from the machine 5 to the workpiece unloading path 51.

  Then, in the process in which the rotation receiving member 2 is rotated to the rotation position 202, the flow-down member 4 is lowered into the work collection box 6. At this time, the flow-down member 4 comes into contact with the workpiece collection surface 61 or another workpiece 8A placed on the workpiece collection surface 61 and bends into a curved shape, and the portion of the flow-down member 4 on the side close to the rotation receiving member 2 In addition, a curved flow surface 41 is formed. 3 and 4 show a case where the flow-down member 4 contacts the workpiece collection surface 61. FIG.

  The curved flow surface 41 is formed as a surface in which the portion located on the upstream side has a steep gradient that is nearly perpendicular to the horizontal direction, and the gradient becomes gentler toward the downstream side. The flow surface 41 is formed as a concave surface for rolling the workpiece 8.

  Next, when the work 8 flows down from the concave receiving surface 21 of the rotation receiving member 2 to the flow lower surface 41 of the flow-down member 4, the work 8 has a flow of momentum in the initial stage of flow, but has a momentum in the final stage of flow-down. It flows down into the work collection box 6 in a state where it is weakened and the momentum of the flow is weakened. The workpiece 8 flows down to the workpiece collection surface 61 of the workpiece collection box 6 or flows down onto another workpiece 8A disposed in the workpiece collection box 6. Thereby, it is possible to make it difficult for an impact to be applied to the work 8 collected from the work carry-out path 51 to the work collection box 6.

  Further, when the rotation receiving member 2 rotates to the rotation position 202, the height from the workpiece collection surface 61 to the workpiece 8 on the concave receiving surface 21 of the rotation receiving member 2 is reduced. In other words, the potential energy when the work 8 flows down is reduced. Then, the workpiece 8 on the concave receiving surface 21 is placed on the workpiece collection surface 61 or the workpiece collection surface 61 via the flow surface 41 of the flow-down member 4 with the height from the workpiece collection surface 61 lowered. It can flow down onto another workpiece 8A. This also makes it difficult to apply an impact to the work 8 when the work 8 is collected in the work collection box 6.

  As described above, in the work shooter 1 of this embodiment, the rotation receiving member 2 temporarily stops the flow of the work 8 flowing down the work carry-out path 51, and the work 8 is again removed from the rotation receiving member 2 to the work collection surface. Flow down to 61. Thereby, the flow-down height from the transfer conveyor 52 to the workpiece collection surface 61 is divided into the flow-down height from the transfer conveyor 52 to the rotation receiving member 2 and the flow-down height from the rotation receiving member 2 to the workpiece collection surface 61. It is done. And the flow-down speed of the workpiece 8 is a speed corresponding to the flow-down height. Therefore, depending on the configuration of the rotation receiving member 2, the speed at which the workpiece 8 flows down when contacting the workpiece collection surface 61 or another workpiece 8 </ b> A placed on the workpiece collection surface 61 is suppressed, and an impact is applied to the workpiece 8. It can be difficult to join.

  Therefore, according to the work shooter 1 of this embodiment, when the work 8 is caused to flow down from the work carry-out path 51 to the work collection surface 61, it is possible to prevent the work 8 from being damaged.

<Embodiment 2>
In this embodiment, as shown in FIG. 6, the rotation receiving member 2 rotates between an initial position 201 and a rotation position 202 in which the opening side 211 of the concave receiving surface 21 is directed to the side. Show about.
The amount of rotation between the initial position 201 and the rotation position 202 of the rotation receiving member 2 according to the positional relationship between the rotation receiving member 2 and the flow-down member 4 and the work collection surface 61, the length of the flow-down member 4, and the like. May be about 90-120 °.

  Moreover, 51 A of workpiece | work carrying-out paths of this form are comprised so that the workpiece | work 8 may be slid in the direction of the center axis line. The rotation receiving member 2 receives the workpiece 8 falling from the workpiece carry-out path 51A.

  Other configurations, operational effects, and the like of the work shooter 1 of the present embodiment are the same as those of the first embodiment. Also in this embodiment, the components indicated by the same reference numerals as those shown in the first embodiment are the same as those in the first embodiment.

<Other embodiments>
Since the flow-down member 4 has flexibility, it can be deformed (flexed) into various shapes according to the movement of the rotation receiving member 2. Therefore, there may be various modes in the manner in which the work 8 flows down on the flow lower surface 41 of the flow-down member 4. For example, even when the rotation receiving member 2 is rotated from the initial position 201 to the rotation position 202, the work 8 may remain mounted on the flow surface 41 of the flow member 4. In this case, when the rotation receiving member 2 rotates from the rotation position 202 to the initial position 201, the workpiece 8 on the flow surface 41 is placed on the workpiece collection surface 61 or the workpiece collection surface 61. It may flow down on the workpiece 8A.

  In addition, as shown in FIGS. 3 and 4 of the first embodiment, the flow member 4 has a curved downstream portion on the opposite side of the upstream portion that forms the flow lower surface 41 in the work collection box 6. It may be bent.

  In addition, when the rotation receiving member 2 is rotated to the rotation position 202 and the downstream end portion 22 of the rotation receiving member 2 approaches the work collection surface 61, the workpiece 8 is rotated by the rotation receiving member. You may fall from the 2 concave receiving surfaces 21 to the flow surface 41. In this case, in the process in which the downstream end 22 of the rotation receiving member 2 moves away from the workpiece collection surface 61, the workpiece 8 placed on the flow surface 41 moves to the workpiece collection surface 61 or the workpiece collection surface 61. It can flow down on another workpiece 8A placed.

  When a plurality of workpieces 8 are unloaded simultaneously from the machine 5, the same number of workpiece unloading paths 51 as the number of unloaded workpieces 8 are installed in the machine 5. Each shooter 1 can be arranged.

  The present invention is not limited only to each embodiment, and further different embodiments can be configured without departing from the scope of the invention. Further, the present invention includes various modifications, modifications within an equivalent range, and the like.
