Japanese Patent Laid-Open No. 2007-118074

  In the prior art as described above, when the overlength component is restrained on the lower side of the regulating member, the head member is hidden behind the regulating member. In particular, since the head member does not protrude to the upstream side of the regulating member, when an operator removes an excessively long part, it is necessary to take out the tool using a tool each time, and it is necessary to improve the workability.

  The present invention is provided in order to solve the above-mentioned problems, and it is possible to smoothly move overlength parts and regulate the delivery, and at the same time simplify the removal work of the regulated overlength parts. The purpose is to provide a structure for restricting the delivery of over-length parts.

Means to solve the problem

  According to the first aspect of the present invention, an excessively long part of a part with a head member that is transported in a suspended state while sliding on the guide surface of the guide rail is subject to regulation. Is provided with a detection member that is opposed to the lower end portion of the excessively long component and that does not contact the lower end portion of the normal-length component. The distance between the reference surface and the guide surface is set to be shorter than the length of the excessively long component and longer than the length of the normal component, and is inclined upward toward the downstream side on the upstream side of the reference surface. This is a structure for restricting the delivery of excessively long parts, characterized in that a guide inclined surface is provided.

The invention's effect

  When the lower end of the overhanging part that has slid on the guide rail in the suspended state reaches the guide inclined surface, it is inclined while being gradually pushed upward by the guide inclined surface, and the head member is moved accordingly. In this state, the lower end slides on the reference surface. After this sliding, the contact at the three locations that the head member contacts the regulating member, the head member contacts the guide surface of the guide rail, and the lower end portion contacts the reference surface is established simultaneously, The transfer of oversized parts is prohibited. Since the excessive parts are gradually moved from the suspended state to the inclined position by the guide inclined surface, the over-parts are smoothly moved and the above three contact points are surely established, and the highly reliable regulation. Function is obtained. Further, the normal-length parts slide on the guide surface and are transferred in a suspended state throughout.

  According to a second aspect of the present invention, the guide surface and the regulating surface are arranged such that the head member of the excessively long component in an inclined state contacts the lower side of the regulating member and a part of the head member is exposed upstream from the regulating member. The over-length component delivery restricting portion structure according to claim 1, wherein a distance from the member is set.

  As described above, since the head member comes into contact with the regulating member after the lower end portion of the excessively long part in the inclined posture starts to slide on the reference surface, the head is set by setting the interval between the guide surface and the regulating member. All the members cannot enter between the regulating member and the guide surface, and a part of the head member can be exposed to the upstream side from the regulating member. Therefore, when removing an abnormal excessively long part, an operator can easily remove the exposed portion by picking up the exposed portion, thereby improving workability.

  Next, the best mode for carrying out the over-part delivery restricting portion structure of the present invention will be described.

  1 and 2 show Example 1. FIG.

  First, a component with a head member will be described.

  The component 1 with a head member is a projection bolt composed of a shaft portion 2 on which a male screw is formed and a flange portion 3 which is an integral head member. The projection for welding for projection welding is formed on the upper surface or the lower surface of the flange portion 3, but is not shown here. In the following description, the projection bolt may be simply expressed as a bolt.

  In the following description, the downstream side means the direction in which parts are transferred, and the upstream side means the opposite.

  Next, the structure of the sending restricting portion will be described.

  Two guide rails 4 are arranged in parallel, and the upper surface thereof is a guide surface 5. A space portion between the guide rails 4 is a passage space portion 6. In the bolt 1, the shaft portion 2 is positioned in the passage space portion 6, and the lower surface of the flange portion 3 slides on the guide surface 5. In this way, the bolt 1 is transferred in a suspended state. Both guide rails 4 are integrated by a coupling plate 7 at the lower part thereof.

  The transfer force for this transfer can be ensured by various methods. For example, as shown in FIG. 1A, the guide rail 4 is inclined and the bolt 1 is slid down, or a normal linear feeder type that applies vibration in the transfer direction to the guide rail 4 arranged horizontally. A thing etc. can be employ | adopted.

  Next, the restriction member and the detection member will be described.

  A regulating member 8 is provided above the guide rail 4 at a predetermined interval from the guide surface 5. The regulating member 8 is opposed to the regulating member 8 so as to contact the lower end portion of the overlong component 1A and to the lower end portion of the normal component 1B. The detection member 9 which does not contact is provided. The detection member 9 is an elongated member fixed to the lower part between the guide rails 4 by bolting or the like. On the upper surface of the detection member 9, the introduction surface 11 is set to a height at which the lower end portion of the excessively long component 1 </ b> A does not come into contact with the detection member 9. The guide inclined surface 12 is formed, and a reference surface 13 formed in a state of being continuous to the guide inclined surface 12 and extending to the wake side is formed. The reference surface 13 is parallel to the guide surface 5. The distance between the guide surface 5 and the introduction surface 11 is set to be longer than the shaft length of the overlong component 1A.

  The distance L1 between the guide surface 5 and the reference surface 13 is set to be shorter than the shaft length of the overlength component 1A and longer than the length of the normal length component 1B. Further, the guide surface 5 and the regulating member 8 are arranged such that the flange portion 3 of the inclined overlength part 1A contacts the lower side of the regulating member 8 and a part of the flange portion is exposed from the regulating member 8 to the upstream side. The interval L2 is set. The regulating member 8 is formed by bending a thick plate, and the upper surface of the flange portion 3 is in contact with the lower corner portion 14 on the front side of the regulating member 8. By setting the distance L2 in this way, a part of the flange portion 3 is projected from the end portion of the regulating member 8 to the upstream side. This protruding length is indicated by L3 in FIG. As shown in FIG. 1 (D), the restricting member 8 is composed of an L-shaped member, and the sliding piece 15 is fixed to the lateral side surface of the guide rail 4 with a bolt 16. The bolt 16 passes through a long hole 17 extending in the vertical direction, and the bolt 16 is loosened so that the height position of the regulating member 8, that is, the interval L2 can be adjusted.

  The interval L2 is set so that the entire flange portion 3 cannot enter between the regulating member 8 and the guide surface 5, and a part of the flange portion 3 is exposed to the upstream side from the regulating member 8. That is, if the distance L2 is too large, the entire flange portion 3 is hidden between the regulating member 8 and the guide surface 5.

  As a modification of the regulating member 8, there is a shape shown by a two-dot chain line in FIG. In other words, this is a bar 18 having a circular cross section arranged in the width direction of the passage space 6. This can be configured by welding a bar 18 to the sliding piece 15.

  The operational effects of the first embodiment described above are as follows.

  When the lower end of the excessively long part 1A that has slid on the guide rail 4 in the suspended state reaches the guide inclined surface 12, it is inclined while being gradually pushed upward by the guide inclined surface 12, and accordingly, the flange The portion 3 is in a state of floating from the guide surface 5, and the lower end portion of the shaft portion 2 slides on the reference surface 13 with this inclined posture. After this sliding, the flange portion 3 contacts the regulating member 8 at the contact point 20, the flange portion 3 contacts the guide surface 5 of the guide rail 4, and the lower end portion contacts the reference surface 13. The contact at the three points of contact at the contact point 22 is established at the same time, and the transfer of the oversized part 1A is prohibited. Since the over-long part 1A is gradually shifted to the inclined posture by the guide inclined surface 12 from the suspended state transfer, the above-mentioned three-point contact is reliably established while the over-long part 1A smoothly moves, and the reliability A highly regulated function. The normal-length component 1B slides on the guide surface 5 and is transported without contacting the detection member 9 in a suspended state throughout.

  The guide surface 5 and the regulating member 8 so that the flange portion 3 of the inclined oversized part 1A contacts the lower side of the regulating member 8 and a part of the flange portion 3 is exposed upstream from the regulating member 8. The interval L2 is set.

  As described above, since the flange portion 3 comes into contact with the regulating member 8 after the lower end portion of the excessively long part 1A in the inclined posture starts to slide on the reference surface 13, the distance L2 between the guide surface 5 and the regulating member 8 is reached. Therefore, all of the flange portion 3 cannot enter between the restricting member 8 and the guide surface 5, and a part of the flange portion 3 is exposed from the restricting member 8 to the upstream side as indicated by a length L 3. State. Therefore, when removing the abnormal overlength component 1A, the operator can easily remove the exposed portion by picking up the exposed portion, thereby improving workability.

  As described above, according to the present invention, the overlength component delivery restricting section can smoothly move the overlength component and regulate the delivery, and at the same time, simplify the operation of removing the regulated overlength component. Since it has a structure, it can be used in a wide range of industrial fields such as automobile body welding processes and home appliance sheet metal welding processes.

It is the side view and sectional drawing of a delivery control part structure. It is a partial expanded side view.
