Japanese Patent No. 3944776

  In the technique described in Patent Document 1, when the supply rod that advances and retreats in the horizontal direction advances and the component reaches the coaxial position with the receiving hole, the air cylinder for insertion subsequently operates to move the component in the vertical direction. It is inserted into the receiving hole. For this reason, it becomes a basic structure in which the supply rod advances and retracts in the horizontal direction with respect to the component insertion direction. Therefore, there is a problem that the operation space of the supply rod with respect to the insertion direction of the parts becomes large, and it is difficult to deploy the device in a narrow place where the peripheral members are expanded in the horizontal direction and are congested.

  The present invention has been provided to solve the above-described problems. By arranging each member of the device along the component supply direction with respect to the receiving hole, the entire device is slimmed in the component supply direction. It is an object of the present invention to provide an apparatus for supplying a shaft-shaped component with a head member that can be formed and that can be reliably transferred.

The invention according to claim 1 is a type in which the supply head holding the component is advanced by the advance / retreat driving means attached to the stationary member and the component is supplied to the receiving hole which is the target location.
The component is a shaft-shaped component with a head member in which a head member is integrated with the shaft portion,
A supply head member protruding in the advancing direction of the output shaft is attached to the base member coupled to the output shaft of the advance / retreat driving means,
In the supply head member, the shaft portion is held by the suction force of the suction means provided on the supply head member to set the relative position between the component and the supply head member, and the output shaft extends in the advancing / retreating direction. A holding groove formed in a state is provided,
Transfer that accommodates the component fed through the component supply path and moves back and forth in a direction that is different from or perpendicular to the advancing / retreating direction of the output shaft by the transfer driving means attached to the stationary member. A member is provided at a position away from the supply head member;
The transfer member has a housing recess formed with a holding surface that supports the head member and performs a stopper function of the component, and communicates with the component supply passage. A passing part is formed that is open in a direction that crosses at a right angle or in a direction that is perpendicular to it,
A part of the head member when the transfer member is moved by the operation of the transfer driving means, the passing portion of the housing recess faces the holding groove and the shaft portion moves from the housing recess to the holding groove. The relative position between the holding surface and the end surface as viewed in the advancing / retreating direction of the output shaft is set so that is positioned at a position that is in close contact with or separated from the end surface of the supply head member. It is a supply apparatus of the shaft-shaped component with a head member.

  A supply head member protruding in the advance direction of the output shaft is attached to the base member coupled to the output shaft of the advance / retreat driving means, and a holding groove formed in the supply head member extends in the advance / retreat direction of the output shaft. It is formed in a state. And the said transfer member is arrange | positioned in the form which advances / retreats in the direction which crossed at right angles with respect to the advance / retreat direction of an output shaft, or the orthogonal direction. As described above, the supply head member extends in the same direction as the output shaft advancement / retraction direction, and the holding groove portion is also arranged in the same direction as the output shaft advance / retreat direction. It is possible to supply parts by arranging the device in a narrow place.

  In addition, the parts housed in the transfer member are transferred to the holding groove portion through the passage portion in a direction perpendicular to or perpendicular to the advancing / retreating direction of the output shaft, so that the transfer is not affected by the advance / retreat space of the supply head member. The transition distance of the members can be shortened, and as a result, slimming of the entire apparatus is realized. That is, the space required for installing the transfer member does not become excessively large in a direction that is perpendicular or perpendicular to the advancing / retreating direction of the output shaft.

  Furthermore, the movement trajectory of the component is an introduction trajectory line in which the component enters the accommodating recess from the component supply passage in the same direction as the output shaft, and a direction perpendicular to the introduction trajectory line and the transfer member is transferred toward the holding groove portion. The transfer locus line, the approach locus line that is transferred from the passage portion of the housing recess to the holding groove portion, and the supply locus line that is supplied toward the receiving hole are formed. Lengths are added to the introduction locus line and supply locus line in the same direction as the output shaft's advance / retreat direction, and the transfer locus line and the entry locus in a direction that is different from or perpendicular to the output shaft's advance / retreat direction. The line can be minimized. Therefore, the entire apparatus can be formed elongated in the advance / retreat direction of the output shaft from the form of the movement trajectory line of the parts, and the parts can be easily supplied to a confined narrow place.

  The component that has entered the receiving recess of the transfer member from the component supply passage is received by the head member being held by the holding surface, and the component is open in a direction that is different from or perpendicular to the advancing / retreating direction of the output shaft. The relative position of the holding surface and the end surface as viewed in the advancing / retreating direction of the output shaft is such that a part of the head member is in close contact with or separated from the end surface of the supply head member. Is set. Therefore, when the supply head member advances toward the receiving hole by the advance operation of the advance / retreat driving means, the head member can be positioned at the earliest position in the advance direction, and the head member can surely enter the receiving hole. .

  According to a second aspect of the present invention, when the head member of the component reaches the vicinity of the receiving hole by the advance operation of the advance / retreat driving means, the end portion of the shaft portion that is held in the holding groove portion is operated. 2. The shaft-shaped component supplying device with a head member according to claim 1, wherein a pressing means for applying a pressing force to the base member is provided in the base member, and the head member is caused to enter the receiving hole by the pressing force. is there.

  Thus, since the pushing force by the pushing means acts on the end portion of the shaft portion at the position where the head member reaches the vicinity of the receiving hole, the shaft portion extends in the length direction of the holding groove portion, that is, the output shaft advances. It is surely entered into the receiving hole while sliding in the direction. Further, since the pushing means is operated at the position where the head member reaches the vicinity of the receiving hole, the supply head member does not collide with the member forming the receiving hole, and reliable component supply is possible. It becomes possible.

  According to a third aspect of the present invention, when the base member moves backward due to the backward movement of the advance / retreat driving means, the pressing force continues to act on the end of the shaft portion, so that the head member enters the receiving hole. It is a supply apparatus of the shaft-shaped components with a head member of Claim 2 comprised so that the complete state might be maintained.

  Thus, when the base member moves backward, the pressing force by the pushing means continues to act on the end of the shaft portion, so when the holding groove portion of the supply head member moves backward, the component enters the receiving hole. It is stationary and still. When the supply head member retracts to a position where the suction force of the suction means with respect to the shaft portion disappears, the pressing force of the pushing means is released. Therefore, when the supply head member is retracted, it is possible to prevent the component from being sucked back by the holding groove portion, and reliable component supply is achieved.

According to a fourth aspect of the present invention, when the component moves from the housing recess to the holding groove, the supply head member and the transfer member are relatively positioned so that a part of the head member is supported by the holding surface. 4. The device according to claim 2 , wherein a position is set, and the presence or absence of a component is detected by operating the pushing means in a state where a part of the head member is supported by the holding surface. It is a supply apparatus of the shaft-shaped components with a described head member.

  The pressing force of the pressing means acts on the component while the shaft portion of the component enters the holding groove and the head member is seated on the holding surface of the receiving recess. Therefore, when the component is present normally, the reaction force of the pressing force of the pushing means is detected to surely determine that the component is present. On the other hand, when there is no part for some reason, the reaction force of the pressing force of the pushing means is not detected, so that the absence of the part is surely determined. As described above, since the pushing means is also used for detecting the presence / absence of a part, the pushing means can be made to function in a multifunctional manner, thereby effectively simplifying the device structure. Furthermore, since the detection operation by the pushing means is executed before the supply operation toward the receiving hole, it is possible to detect in advance the abnormal situation of the absence of the component, and to perform the supply operation in the absence of the component. It is possible to avoid a wasteful supply operation such as.

  In the invention according to claim 5, when the head member of the component reaches the vicinity of the receiving hole by the advance operation of the advance / retreat driving means, suction means for causing the head member to enter the receiving hole, It is a supply apparatus of the shaft-shaped components with a head member of Claim 1 installed in the member which forms the said receiving hole.

  Since the head member that has reached the vicinity of the receiving hole is drawn into the receiving hole by the suction means, it is not necessary to arrange the pushing means as described above in the base member, which is advantageous for simplifying the structure.

  The invention according to claim 6 is a passage through which the head member can relatively pass when the transfer member located at a position facing the supply head member returns to a position communicating with the component supply passage. It is a supply apparatus of the shaft-shaped component with a head member in any one of Claims 1-5 in which space is formed in a part of said transfer member.

  Since a passage space through which the head member can relatively pass is formed in a part of the transfer member, a part of the head member relatively slides on the holding surface in a state where the shaft portion enters the holding groove portion. The transfer member can be retracted. For this reason, the relative positions of the end surfaces of the head member and the supply head member are accurately maintained. Thereby, the state which the head member protruded from the end surface of the supply head member is securable. Further, when the transfer member moves backward, a part of the transfer member does not interfere with the head member, so that the transfer member can be smoothly moved backward.

  The present invention is an apparatus invention as described above, but as can be seen from the embodiments described below, it can exist as a method invention that specifies the movement trajectory of components, the operation of components, and the like.

It is the side view which shows the whole apparatus, a top view, and the three-dimensional figure of components.

It is the front view of a transfer member, a side view, a top view, and sectional drawing. It is sectional drawing and a top view which show the transition state of components. It is a side view which shows the operation state of a pushing means. It is a diagram which shows the movement locus | trajectory of components. It is a side view which shows the modification of a pushing means. It is a side view which shows another Example.

  Below, the form for implementing the supply apparatus of the shaft-shaped components with a head member of this invention is demonstrated.

  1 to 7 show Embodiment 1 of the present invention.

  First, components handled in this embodiment will be described.

  As shown in FIG. 1D, the component 1 handled in the apparatus of the present invention is a shaft-shaped component with a head member in which a head member 3 is integrated with a straight shaft portion 2 having a circular cross section. As the shape of the head member 3, there are various types such as a circular flange portion, a plate-shaped square member, and a cylindrical member having a diameter larger than that of the shaft portion 2, and here, the flange portion 3 is used. The illustrated part 1 is a rivet that is caulked and is made of iron. The dimensions of each part of the rivet 1 are such that the diameter and length of the shaft part 2 are 5.5 mm and 16 mm, respectively, and the diameter and thickness of the flange part are 13 mm and 2.5 mm, respectively.

  Next, the overall structure of the apparatus will be described.

  The entire apparatus is indicated by reference numeral 100. A straight passage member 5 is fixed to a stationary member 4 such as a machine frame, and a component supply passage 6 having a circular cross section extending in the vertical direction is formed therein. The rivet 1 is sent from the parts feeder 7 to the parts supply passage 6 by pneumatic conveyance or the like. Reference numeral 8 denotes a supply hose made of a flexible synthetic resin such as urethane resin, and connects the parts feeder 7 and the passage member 5.

  A vertical support member 9 made of a thick plate member is fixed to a passage member 5 which is a stationary member in a state of extending downward. This fixing is performed by bolting, welding, or the like, and the fixing portion is indicated by a one-dot chain line in the figure. The other fixed portions are also illustrated by the similar one-dot chain line. A horizontal support member 10 made of a thick plate member is fixed to the lower end of the vertical support member 9, and a transfer member described later is accommodated by the lower surface of the passage member 5, the inner surface of the vertical support member 9, and the upper surface of the horizontal support member 10. An accommodation space 11 is formed.

  Next, the transfer member will be described.

  The transfer member 13 is formed by processing a rectangular parallelepiped block material, and is provided with an accommodation recess 14 for accommodating the rivet 1 that has passed through the component supply passage 6. The space of the accommodating recess 14 extends in the vertical direction, and is provided with a passing portion 15 opened on one side, and when the transfer member 13 is placed at the standby position, as shown in FIG. The housing recess 14 communicates with the component supply passage 6. The receiving recess 14 is formed with a holding surface 16 that receives and supports the flange 3 of the rivet 1 that has entered. The holding surface 16 is constituted by a flat upper surface of a plate member 17 formed at the end of the housing recess 14.

  The transfer member 13 is housed in the housing space 11 and supported so as to advance and retreat in the longitudinal direction of the component supply passage 6, that is, in a direction orthogonal to the vertical direction. The transfer driving means 18 for moving the transfer member 13 back and forth is attached to the stationary member 4. The stationary member 4 in this embodiment is a thick plate-like bracket 19 coupled to the passage member 5, and a transfer driving means 18 is attached thereto. The transfer driving means 18 may be any one that outputs and retreats, and an air cylinder, a reciprocating output type electric motor, or the like can be adopted. Here, the former air cylinder is denoted by reference numeral 18. A coupling member 21 is fixed to the tip of the piston rod 20, and the other end of the coupling member 21 is fixed to the end surface of the transfer member 13.

  Next, the supply head member will be described.

  The advancing / retreating drive means 23 fixed to the stationary member 4 may be anything that outputs advancing / retreating, and an air cylinder, an advancing / retracting output type electric motor or the like can be adopted. Here, the former air cylinder is denoted by reference numeral 23. The output shaft of the air cylinder 23 is constituted by a piston rod 24, and the advance / retreat axis OO of the output shaft 24 is arranged in the vertical direction. The longitudinal direction of the component supply passage 6 is parallel to the advance / retreat axis OO. A base member 25 composed of a thick plate member is fixed to the tip of the piston rod 24, and a supply head member 26 coupled to the base member 25 protrudes in the advancing direction of the piston rod 24.

  The supply head member 26 includes a main body portion 27 fixed just below the center of the base member 25 and a holding portion 28 extending from the main body portion 27 in a direction away from the advance / retreat axis OO in the horizontal direction. Yes. A holding groove portion 30 is formed on the side surface 29 of the holding portion 28 so as to extend in the forward / backward direction of the piston rod 24. The holding groove portion 30 is a portion into which the shaft portion 2 is fitted, and an inner surface thereof is an arc surface. When the shaft portion 2 is fitted into the holding groove portion 30, the relative position between the rivet 1 and the supply head member 26 is set correctly. Thus, in the state in which the shaft portion 2 is supported by the holding groove portion 30, the shaft portion 2 is in the vertical direction.

  In order to hold the shaft portion 2 in the holding groove portion 30, suction means 31 is provided in the supply head member 26. As the suction means 31, one that is attracted by air vacuum or one that is attracted by a magnet can be employed. Here, a permanent magnet disposed in the vicinity of the holding groove 30 is employed, and this permanent magnet is also denoted by reference numeral 31.

  A target location for supplying the rivet 1 is a receiving hole 33, which is formed on a member 34 fixed to the stationary member 4. The receiving hole 33 is circular, and the bottom surface 35 is formed as a flat surface. In addition, a permanent magnet 36 as a suction means is embedded behind the receiving hole 33, that is, below, so that the rivet 1 that is received in the receiving hole 33 and the flange portion 3 is in close contact with the bottom surface 35 does not fall down. Yes.

  Next, the pushing means will be described.

  The pushing means 37 is provided on the base member 25, and when the flange portion 3 of the rivet 1 reaches the vicinity of the receiving hole 33, that is, immediately before the opening portion of the receiving hole 33 by the advance operation of the air cylinder 23, it stops. Operate. By this operation, the pressing force by the pushing means 37 acts on the end portion of the shaft portion 2 held in the holding groove portion 30. The flange portion 3 is caused to enter the receiving hole 33 by the pressing force. As the push-in means 37, various devices such as an air cylinder and an advancing / retracting output type electric motor can be adopted. Here, the former air cylinder is adopted, and the reference numeral 37 is also given to this air cylinder.

  When the piston rod of the air cylinder 37 is a component pressing rod 38 and the flange portion 3 reaches just before the receiving hole 33, the component pressing rod 38 advances and hits the end of the shaft portion 2 so that the flange portion 3 5, it is pushed into the receiving hole 33. The flange portion 3 is in close contact with the bottom surface 35 of the receiving hole 33 and has a stable standing posture by the attractive force of the permanent magnet 36.

  Further, when the base member 25 is retracted by the retracting operation of the air cylinder 23, the pressing force of the component pressing rod 38 continues to act on the end of the shaft portion 2 as shown in FIG. The state in which the hole 33 is completely inserted is maintained. In order to execute such a state, air supply / discharge to both the air cylinders 23 and 37 is controlled so that the piston rod 38 of the air cylinder 37 continues to advance when the air cylinder 23 moves backward. ing. That is, the advancing operation of the air cylinder 37 is performed in synchronization with the retreating operation of the air cylinder 23. In this way, the rivet 1 is sandwiched between the tip of the component pressing rod 38 and the bottom surface 35 of the receiving hole 33. When the permanent magnet 31 is separated from the shaft portion 2 by the return operation of the air cylinder 23 and the attracting force of the permanent magnet 31 substantially disappears, the component pressing rod 38 moves backward and the supply of the rivet 1 to the receiving hole 33 is completed. To do.

  When the applied pressure of the air cylinder 37 exceeds the applied pressure of the air cylinder 23, the piston rod 24 of the air cylinder 23 is pushed into the air cylinder 23 by the pressure reaction force of the air cylinder 37. If this happens, the supply head member 26 is returned (floated) to the position indicated by the two-dot chain line in FIG. 5, so that the rivet 1 may fall. Therefore, the above described problem is prevented by setting the pressure of the air cylinder 37 to be lower than the pressure of the air cylinder 23.

  Next, the positional relationship between the transfer member and the supply head member will be described.

  As shown in FIGS. 1B, 2, 4, and the like, when the transfer member 13 is moved by the operation of the air cylinder 18, the side surface 22 of the transfer member 13 and the side surface 29 of the supply head member 26 are parallel at a slight interval. Face each other. Therefore, the mounting posture of the air cylinder 18 is set so that the advancing / retreating direction of the piston rod 20 advances / retreats in a direction that is perpendicular to the advancing / retreating axis OO. In this way, the transfer member 13 advances and retreats in a direction that is perpendicular to the advance / retreat axis OO. The distance when the side surface 22 and the side surface 29 face each other is 2 mm.

  As apparent from FIG. 4, in the state where the transfer member 13 has returned to the position matching the component supply passage 6, that is, in the X position, the transfer member 13 exists at a position away from the supply head member 26 and passes through the receiving recess 14. The part 15 is open in a direction that is perpendicular to the advance / retreat axis OO. Since the housing recess 14 is sealed by the inner surface of the vertical support member 9, the rivet 1 that has entered the housing recess 14 does not accidentally fall from the housing recess 14. When the transfer member 13 moves forward by the operation of the air cylinder 18 and the passage portion 15 matches the holding groove portion 30, the rivet 1 moves to the supply head member 26 side by the attractive force of the permanent magnet 31, and the shaft portion 2 moves to the holding groove portion 30. To be accepted. The state in which the transfer member 13 is waiting at a separated position is indicated by a distance L shown in FIG.

  When the passage portion 15 and the holding groove portion 30 face each other, that is, in the Y position, as shown in FIG. 4, a part of the flange portion 3 is placed on the holding surface 16 and the shaft portion 2 is held. It is received in the groove 30. In order to realize such a state, the relative position between the supply head member 26 and the transfer member 13 is set to 2 mm as described above, and the depth of the holding groove 30 is set not to be too deep. . FIG. 4B shows a cross section taken along the line BB in FIG. FIG. 1C shows a CC cross section of FIG.

  As shown in FIG. 4, the rivet 1 enters the accommodation recess 14 from a direction perpendicular to the paper surface of FIG. 4A, and then the transfer member 13 is moved to the right in FIG. Moves toward the holding groove 30 and finally the transfer member 13 returns to the left. Since part of the flange portion 3 is placed on the holding surface 16 during such a return operation, it is necessary to prevent a part of the transfer member 13 from interfering with the flange portion 3 when the transfer member 13 is returned. There is. Therefore, a passage space 39 is provided in a part of the transfer member 13, and when the transfer member 13 is thereby restored, the flange portion 3 relatively passes through the passage space 39. The passage space 39 is formed by notching the lower portion of the end wall member 40 of the transfer member 13 and is in a state of being connected to the holding surface 16.

  When the transfer member 13 moves and the passage portion 15 of the receiving recess 14 faces the holding groove 30 and the shaft portion 2 moves from the receiving recess 14 to the holding groove 30, a part of the flange portion 3 is supplied to the supply head member 26. The relative positions of the holding surface 16 and the end surface 41 as viewed in the advancing and retreating direction of the piston rod 24 are set so as to be located at a place separated from the end surface 41 on the advancing side. As is clear from FIG. 4B, there is a gap between the upper surface of the flange portion 3 and the end surface 41, and the flange portion 3 is the earliest position during the supply operation. A part of the flange portion 3 may be in close contact with the end face 41 so that the gap is not formed.

  As a modified example, as shown in FIG. 4C, the end surface 41 may have a step shape. Further, as shown by a two-dot chain line in FIG. 3A, a tapered portion 42 can be formed so that the rivet 1 can smoothly enter the receiving recess 14.

  Next, detection of the presence or absence of rivets will be described.

  As described above, the rivet 1 is moved from the housing recess 14 to the holding groove 30 and a part of the flange 3 is supported by the holding surface 16, so that the pushing means (air cylinder) 37 is operated and the rivet 1 is operated. 1 is detected (see FIG. 4B). When the component pressing rod 38 hits the upper end of the shaft portion 2 by the operation of the air cylinder 37, a part of the flange portion 3 is seated on the holding surface 16, so that the component pressing rod 38 is stopped and the air pressure of the air cylinder 37 is stopped. Rises. This pressure increase is converted into an electrical signal, and it is detected that the rivet 1 is present normally. Subsequent to this detection, the component pressing rod 38 returns to its original position, and subsequently, the feeding head member 26 advances by the retreat of the transfer member 13 and the advancement of the air cylinder 23. Finally, the flange is formed by the pushing operation of the air cylinder 37. The part 3 is supplied to the receiving hole 33. When the supply head member 26 advances as described above, the component pressing rod 38 is once returned to the original position and then advanced.

If the rivet 1 is not fed into the receiving recess 14 due to a trouble on the part feeder 7 side, the component pressing rod 38 has an abnormal advance stroke, and this excessive stroke is converted into an electric signal so that the rivet 1 is normal. Is detected not to exist .

  Detection of the increase in air pressure when the rivet 1 is present and converting it into an electric signal can be easily detected by using a pressure sensor that is generally used. Further, the excessively long stroke of the component pressing rod 38 can be easily converted into an electric signal by a photo sensor (not shown) attached to the holding portion 28 of the supply head member 26.

  Next, the movement trajectory of the rivet will be described.

  FIG. 6 is a movement locus diagram of the rivet 1. The movement locus line is an introduction locus line 43 in which the rivet 1 enters the housing recess 14 from the component supply passage 6, and a movement locus in a direction perpendicular to the introduction locus line 43 and the transfer member 13 is moved toward the holding groove portion 30. The line 44, the approach locus line 45 that is transferred from the passage portion 15 of the housing recess 14 to the holding groove portion 30, and the supply locus line 46 that supplies the rivet 1 toward the receiving hole 33 are formed.

  In the above-described embodiment, the transfer member 13 moves along the transfer locus line 44. However, instead of such a locus line 44, as shown in FIG. It is also possible to do. In order to do so, the transfer member 13 shown in FIG. 1B is arranged on the right side of the cross-sectional line CC, and the structure is changed so that the housing recess 14 approaches from right next to the holding groove 30. . By changing in this way, the transfer member 13 advances and retreats in a direction orthogonal to the advance / retreat axis OO, and the passage portion 15 of the housing recess 14 opens in a direction orthogonal to the advance / retreat axis OO. Become.

  In the above embodiment, the operation direction of the related member is set based on the advance / retreat axis OO which is the advance / retreat direction line of the output shaft, and the advance / retreat axis OO is arranged in the vertical direction. However, it is also possible to change the installation posture of the apparatus by inclining the advancing / retreating axis OO or making it horizontal.

  A modification of the pushing means will be described.

  The push-in means described above is a push-push type using the component push rod 38, but the modified example shown in FIG. 7 utilizes air injection. That is, the downward nozzle 47 is fixed to the base member 25, and the air hose 48 is connected to it. The other configuration is the same as that of the previous embodiment, including a portion not shown, and the same reference numerals are given to members having similar functions.

  When the flange portion 3 stops immediately before the receiving hole 33 by the operation of the air cylinder 23, air is injected from the nozzle 47 onto the end surface of the shaft portion 2, and the flange portion 3 is pushed into the receiving hole 33. Thereafter, when the supply head member 26 returns, the air injection is continued and the rivet 1 is prevented from being returned. Such an operation is the same as the operation of the component pressing rod 38 described above.

  It should be noted that an electric motor that performs forward / backward output can be employed instead of the various air cylinders. It is also possible to replace the various permanent magnets with electromagnets.

  The above-described operation can be easily performed by a generally employed control method. A predetermined operation can be ensured by combining an air switching valve that operates with a signal from the control device or the sequence circuit, a sensor that emits a signal at a predetermined position of the air cylinder, and transmits the signal to the control device.

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

  A supply head member 26 is attached to a base member 25 coupled to the piston rod 24 of the air cylinder 23 so as to protrude in the advancing direction of the piston rod 24 (to the advance / retreat axis OO). The holding groove portion 30 is formed in a state extending in the forward / backward direction of the piston rod 24. The transfer member 13 is arranged in such a manner as to advance and retract in a direction that is perpendicular to the advancing and retreating direction of the piston rod 24. As described above, the supply head member 26 extends in the same direction as the forward / backward direction of the piston rod 24, and the holding groove 30 is also disposed in the same direction as the forward / backward direction of the piston rod 24. The apparatus can be arranged in a slim shape, and the apparatus 100 can be arranged in a narrow place to supply rivets.

  Further, the rivet 1 accommodated in the transfer member 13 is moved through the passage portion 15 in a direction perpendicular to the advancing / retreating direction of the piston rod 24 or in a direction orthogonal thereto, and therefore is affected by the advancing / retreating space of the supply head member 26. Therefore, the transfer distance of the transfer member 13 can be shortened, and as a result, the entire apparatus 100 can be slimmed. That is, the space required for installing the transfer member 13 does not become excessively large in a direction that is perpendicular to or perpendicular to the advancing / retreating direction of the piston rod 24.

  Further, the movement trajectory of the rivet 1 is perpendicular to the introduction trajectory line 43 where the rivet 1 enters the housing recess 14 from the component supply passage 6 in the same direction as the piston rod 24, and is held by the transfer member 13. A transfer trajectory line 44 in the direction of transfer toward the groove 30, an entry trajectory line 45 transferred from the passing portion 15 of the housing recess 14 to the holding groove 30, and a supply trajectory line 46 supplied toward the receiving hole 33. Is formed by. The introduction trajectory line 43 and the supply trajectory line 46 in the same direction as the forward / backward direction of the piston rod 24 are given lengths as necessary, and the transfer trajectory in a direction that is different from or perpendicular to the forward / backward direction of the piston rod 24. The line 44 and the approach locus line 45 can be shortened. Accordingly, the entire apparatus 100 can be formed elongated in the advancing / retreating direction of the piston rod 24 from the form of the movement trajectory line of the rivet 1, and the rivet supply to a confined narrow place can be easily performed.

  The rivet 1 that has entered the accommodating recess 14 of the transfer member 13 from the component supply passage 6 is received by the flange portion 3 by the holding surface 16, and the rivet 1 is in a direction that is different from or perpendicular to the advancing and retreating direction of the piston rod 24. The piston rod is moved so as to move from the passing portion 15 opened in the direction to the holding groove portion 30, and a part of the flange portion 3 is located in close contact with the end surface 41 of the supply head member 26 or at a position separated from the end surface 41. The relative positions of the holding surface 16 and the end surface 41 viewed in the 24 advance / retreat directions are set. Therefore, when the supply head member 26 advances toward the receiving hole 33 by the advancing operation of the air cylinder 23, the flange portion 3 can be positioned at the foremost position in the advancing direction, and the flange portion 3 can be reliably inserted into the receiving hole 33. Can enter.

  Push-in operation is performed when the flange portion 3 of the rivet 1 reaches the vicinity of the receiving hole 33 due to the advancing operation of the air cylinder 23 to apply a pressing force to the end portion of the shaft portion 2 held in the holding groove portion 30. Means, that is, an air cylinder 37 is provided on the base member 25, and the flange portion 3 is made to enter the receiving hole 33 by the pressing force of the air cylinder 37.

  Thus, since the pushing force by the pushing means 37 acts on the end portion of the shaft portion 2 at the position where the flange portion 3 reaches the vicinity of the receiving hole 33, the shaft portion 2 is applied to the inner wall of the holding groove portion 30 in the length direction. In other words, it is surely entered into the receiving hole 33 while sliding in the advancing direction of the output shaft OO. Further, since the pushing means 37 is operated at the position where the flange portion 3 reaches the vicinity of the receiving hole 33, the supply head member 26 does not collide with the member 34 forming the receiving hole 33, and the reliability is improved. Highly efficient rivet supply is possible.

  When the base member 25 moves backward by the backward movement of the advance / retreat driving means 23, the pressing force of the pushing means 37 continues to act on the end of the shaft portion 2, so that the flange portion 3 has completely entered the receiving hole 33. Configured to be maintained.

  Thus, when the base member 25 moves backward, the pressing force by the pushing means 37 continues to act on the end portion of the shaft portion 2, so that when the portion of the holding groove portion 30 of the supply head member 26 moves backward, the rivet Reference numeral 1 stands still in a state where it has entered the receiving hole 33, that is, in a state where the surface of the flange portion 3 is in close contact with the bottom surface 35 of the receiving hole 33. When the supply head member 26 is retracted to a position where the suction force of the suction means 31 with respect to the shaft portion 2 disappears, the pressing force of the pushing means 37 is released. Therefore, when the supply head member 26 moves backward, the rivet 1 can be prevented from being sucked back by the portion of the holding groove 30 and a reliable rivet supply is achieved.

  When the rivet 1 moves from the receiving recess 14 to the holding groove 30, the relative position between the supply head member 26 and the transfer member 13 is set so that a part of the flange 3 is supported by the holding surface 16. The pushing means 37 is operated in a state where a part of the rivet 1 is supported by the holding surface 16 to detect the presence or absence of the rivet 1.

  The pressing force of the pressing means 37 acts on the end of the shaft 2 while the shaft 2 of the rivet 1 enters the holding groove 30 and the flange 3 is seated on the holding surface 16 of the receiving recess 14. Therefore, when the rivet 1 is present normally, the reaction force of the pressing force of the pushing means 37 is detected to reliably determine that the rivet 1 is present. On the other hand, when the rivet 1 does not exist for some reason, the reaction force of the pressing force of the pushing means 37 is not detected, so that the absence of the rivet 1 is surely determined. Thus, since the pushing means 37 is also used for detecting the presence or absence of the rivet 1, the pushing means 37 can be multifunctionally functioned to effectively simplify the device structure. Further, since the detection operation by the pushing means 37 is executed before the supply operation toward the receiving hole 33, it is possible to detect in advance an abnormal situation of the absence of rivets, and supply in the absence of rivets. It is possible to avoid useless supply operation such as operation.

  When the transfer member 13 located at a position facing the supply head member 26 returns to the position communicating with the component supply passage 6, a passage space 39 through which the flange portion 3 can relatively pass is one of the transfer members 13. It is formed in the part.

  Since the passage space 39 through which the head member 3 can relatively pass is formed in a part of the transfer member 13, a part of the flange part 3 is on the holding surface 16 in a state where the shaft part 2 enters the holding groove part 30. The transfer member 13 can be retracted while sliding relatively. For this reason, the relative position of the flange part 3 and the end surface 41 of the supply head member 26 is accurately maintained. As a result, it is possible to ensure that the flange portion 3 protrudes from the end surface 41 of the supply head member 26. Moreover, since a part of the transfer member 13 does not interfere with the flange portion 3 when the transfer member 13 is retracted, the transfer member 13 is smoothly retracted.

  As shown in FIG. 1 (B), a coupling member 21 disposed at the tip of the piston rod 20 in a direction orthogonal to the piston rod 20, and a state in which the piston rod 20 is fixed to the coupling member 21 and extends in the backward direction. Due to the transfer member 13, the piston rod 20, the coupling member 21, and the transfer member 13 are arranged in a substantially U shape. Therefore, the transfer member 13 is not directly coupled to the tip of the piston rod 20, and there is an effect that the space seen in the forward / backward direction of the air cylinder 18 can be reduced. Further, as shown in FIG. 1B and FIG. 2, the holding unit 28 of the supply head member 26 and the air cylinder 18 are arranged to face each other, and the transfer member 13 is a space between the holding unit 28 and the air cylinder 18. 32 is entered. Therefore, the members such as the holding unit 28, the transfer member 13, and the air cylinder 18 can be gathered in a compact manner.

  FIG. 8 shows a second embodiment of the present invention.

  In this embodiment, the pushing means in the previous embodiment is stopped and the rivet 1 is sucked into the receiving hole 33. A suction means is incorporated in the member 34 provided with the receiving hole 33. Although various means such as a magnet or an air suction system can be adopted as the suction means, here, the former magnet is used, and a permanent magnet 49 is used. The attractive force of the permanent magnet 49 is set to be stronger than the attractive force of the permanent magnet 31 that acts on the shaft portion 2 held in the holding groove 30. Other configurations are the same as those of the first embodiment including the portions not shown, and members having the same functions are denoted by the same reference numerals.

  By doing so, when the flange portion 3 stops immediately before the receiving hole 33, the attractive force of the permanent magnet 49 exceeds the attractive force of the permanent magnet 31, so the rivet 1 is forcibly drawn into the receiving hole 33, Parts supply is completed.

  The operational effects of the second embodiment are as follows.

  The suction means 49 for allowing the flange portion 3 to enter the receiving hole 33 when the flange portion 3 of the rivet 1 reaches the vicinity of the receiving hole 33 by the advance operation of the advance / retreat driving means 23 forms the receiving hole 33. It is installed on the member 34.

  Since the flange portion 3 that has reached the vicinity of the receiving hole 33 is drawn into the receiving hole 33 by the permanent magnet 49, it is not necessary to arrange the pushing means 37 as described above in the base member 25, which is advantageous for simplifying the structure. .

  As described above, according to the apparatus of the present invention, by arranging each member of the apparatus along the component supply direction with respect to the receiving hole, the entire apparatus can be formed slim in the component supply direction, Moreover, the parts can be reliably transferred. Therefore, it can be used in a wide range of industrial fields, such as an automobile body assembly process and a home appliance sheet metal assembly process.
