[0013] An embodiment of the blanking device according to the present invention will be described with reference to the drawings. In the following description, for the arrows shown in each drawing, F is the front, B is the rear, R is the right, L is the left, U is the top, and D is the bottom. Note that in FIG. 5, the air joint 159 is omitted for ease of understanding of the invention.

[0014] The blanking device 100 of this embodiment is generally configured such that, as shown in FIGS. 1 and 2, bolts B sent from the supply device 40 exemplified by the parts feeder pass through the guide chute 200 and are blanked one by one by the blanking device 100, and then supplied to the parts supply unit 30 provided in the resistance welder 10.

[0015] The configuration of the supply device 40 is the same as that used in the supply device for small parts of Japanese Patent Application No. 2011-210053 (Japanese Patent Laid-Open No. 2013-71788) and the sorting structure of the supply device for small parts of Japanese Patent Application No. 2023-42816, which were previously made by the applicant, so detailed description is omitted.

[0016] Also, the guide chute 200 is the same as the configuration of Japanese Patent Application No. 2023-42816, which was previously made by the applicant, so detailed description is omitted.

[0017] The parts supply unit 30 is used in the resistance welder 10. Generally, as shown in FIG. 8 and the like, for a bolt B having a head B1 and a shaft portion B2, the bolt B fed from the blanking device 100 is received by the upper movable electrode 16, placed on a flat workpiece (not shown) arranged on the lower fixed electrode 18, and the bolt B and the workpiece are clamped by the movable electrode 16 and the fixed electrode 18 and energized, so that the bolt B can be welded to the workpiece.

[0018] Note that the component supply unit 30 can be exemplified by those of Japanese Utility Model Application No. 2023-4266 etc. previously filed by the applicant of the present application.

[0019] As shown in FIGS. 3 to 8 etc., the blanking device 100 includes a chute 130, blanking means 140, and a component supply pipe 180.

[0020] The chute 130 includes a chute forming member 131A, a chute forming member 131B, and a proximity sensor 134.

[0021] The chute forming member 131A and the chute forming member 131B are made of metal, formed in a long rectangular parallelepiped shape, and arranged to face each other with a gap in the front-rear direction. The upper corner portions of the chute forming member 131A and the chute forming member 131B that face each other are cut away so as to be inclined surfaces. That is, the chute forming member 131A and the chute forming member 131B have symmetrical shapes in the front-rear direction.

[0022] A flat bracket 110 is disposed between the chute forming member 131A and the chute forming member 131B, and the chute 130 is formed by being bolted. The chute 130 is further attached to the supply device 40 via another bracket 111.

[0023] Also, the chute 130 is connected to the left lower end of the guide chute 200 at the right end so as to be able to transfer the bolt B.

[0024] A sensor bracket 133 is attached to the chute forming member 131A so as to extend upward. A proximity sensor 134 for detecting the presence or absence of the bolt B is attached to the sensor bracket 133.

[0025] In the present embodiment, the proximity sensor 134 is disposed at the central portion in the feeding direction of the bolt B of the chute forming member 131A and the chute forming member 131B.

[0026] A chute cover 135, which is formed in a substantially L-shaped cross section so as to cover the upper surface sides of the chute forming members 131A and 131B except for the portions corresponding to the proximity sensor 134, is attached. The portion of the chute cover 135 corresponding to the proximity sensor 134 is cut out.

[0027] A component passage 136 through which the bolt B passes is formed by a gap between the chute forming members 131A and 131B and the chute cover 135.

[0028] The cutting means 140 includes a base plate 151, a main body 153, a sub-plate 156, an upper plate 158, a cylinder bracket 160, an air cylinder 161, and a switching member 165.

[0029] The base plate 151 is made of metal and is formed in a rectangular flat plate shape, and an insertion hole 152 through which the component supply pipe 180 can be inserted is provided. The main body 153 is attached to the upper surface side of the base plate 151.

[0030] The main body 153 is made of metal and is formed in a cubic shape. A front passage groove 153a, which is formed by cutting away in a substantially semi-elliptical hole shape when viewed from the right side toward the left side and along the bolt B feeding direction, is formed in the main body 153.

[0031] A passage hole 153b, which is formed as a circular through hole from the upper surface to the lower surface of the main body 153, communicates with the front passage groove 153a and an insertion hole 180a (to be described later) of the component supply pipe 180, and allows the bolt B to pass through.

[0032] A guide surface 153c, which is formed by cutting away from the upper surface to the lower surface of the main body 153 while leaving the left rear corner portion, is formed in the main body 153 to guide the rotation of the switching member 165. The convex portion of the left rear corner portion of the main body 153 serves as a stopper 153d that restricts the rotation of the switching member 165.

[0033] On the right side of the main body 153 and on the rear side in the feeding direction of the bolt B on the upper surface of the base plate 151, a sub-plate 156 is attached.

[0034] The sub-plate 156 is made of metal, formed in a rectangular flat plate shape, and a rear through groove 156a is formed by cutting it in a semi-long hole shape from the upper surface to the lower surface and as viewed from the feeding direction of the bolt B.

[0035] At the upper left corner portion of the sub-plate 156, a guide surface 156b for guiding the movement of the switching member 165 is formed by cutting it from the upper surface to the lower surface.

[0036] The front through groove 153a and the rear through groove 156a communicate with each other so that the shaft portion B2 of the bolt B can pass through.

[0037] The guide surface 153c and the guide surface 156b are continuously provided in a flush state to form a guide surface for guiding the movement of the switching member 165.

[0038] An upper plate 158 is attached to the upper surface of the main body 153 and the sub-plate 156.

[0039] The upper plate 158 is made of metal, formed in a rectangular flat plate shape, and a window groove 158a is formed by cutting it in a semi-long hole shape from the right surface to the left surface side, orthogonal to the bolt B feeding direction, and as viewed obliquely from above, so that the bolt B can be visually recognized.

[0040] An air joint 159 is attached to the window groove 158a. The air joint 159 is connected to an air compressor (not shown). The air joint 159 supports the feeding of the bolt B to the component supply unit 30 by air pressure feeding.

[0041] A metal cylinder bracket 160 is attached to the lower surface of the base plate 151. The cylinder bracket 160 extends forward and then is bent upward about the front-rear direction axis, and is formed in a substantially L shape as viewed from the bolt B feeding direction.

[0042] A shaft support bracket 163 formed in a substantially U-shaped cross section is disposed on the cylinder bracket 160. The shaft support bracket 163 is attached to the upper part of the cylinder bracket 160.

[0043] An air cylinder 161 as a first driving means is attached to the shaft support bracket 163 so as to be rotatable about an axis inclined with respect to the vertical direction. A shaft support block 164 is attached to the tip of the cylinder rod 162 of the air cylinder 161.

[0044] The shaft support block 164 is made of metal and is formed in a substantially U shape with the left side open, and is rotatably attached to a shaft support portion 169 of a switching member 165 described later about an axis inclined with respect to the vertical direction.

[0045] The switching member 165 is made of metal and is formed in a rectangular flat plate shape as shown in FIG. 7 and the like, and has a locking portion 166 capable of locking the bolt B, a head passing portion 167 through which the head B1 can pass, a passage portion 168 communicating the locking portion 166 and the head passing portion 167, and a shaft support portion 169 supported by the shaft support block 164.

[0046] In the present embodiment, when the switching member 165 is in a component receiving position described later, the locking portion 166 is formed in a square shape so as to be orthogonal to the bolt B feeding direction and communicate with a passage through which the bolt B of the chute 130 passes as viewed obliquely upward. The locking portion 166 is formed such that the end surface on the front side in the bolt B feeding direction is inclined. The locking portion 166 is capable of locking the head B1 in a state where the shaft portion B2 is inserted in the thickness direction.

[0047] The head passage portion 167 is formed as a circular through-hole penetrating in the thickness direction, can communicate with the passage hole 153b of the main body 153, and the head B1 can pass through, in other words, the bolt B can pass through.

[0048] The passage portion 168 communicates the locking portion 166 and the head passage portion 167, and the upper corner portions at both ends are chamfered.

[0049] The shaft support portion 169 is formed to protrude in a rectangular parallelepiped shape, and is pivotally supported by the pivot support block 164 so as to be rotatable about an axis inclined with respect to the vertical direction.

[0050] Further, the switching member 165 has an entrance portion 170 and a restricting portion 171.

[0051] The entrance portion 170 is formed in a substantially triangular shape that can enter between the shaft portion B2 of the bolt B located at the very front of the standby portion 120 and the shaft portion B2 of the bolt B located one feed direction rearward of the bolt B.

[0052] The restricting portion 171 is disposed in a part of the entrance portion 170, is formed as an arc surface concentric with the rotation axis of the switching member 165, and is formed so as to contact the shaft portion B2 of the bolt B and restrict it from being sent to the component supply pipe 180.

[0053] The switching member 165 is disposed on the guide surface 153c of the main body 153 and the guide surface 156b of the sub-plate 156, and is disposed so as to cover the upper surface side of the upper plate 158, and is rotatably attached to the main body 153 and the upper plate 158 using the shaft member 172.

[0054] The switching member 165 is rotatably attached to the pivot support block 164 at the shaft support portion 169 using the shaft member 173.

[0055] The lower surfaces of the chute forming members 131A and 131B and the upper surface of the base plate 151 are connected.

[0056] From the above, when the switching member 165 is at the component receiving position shown in FIG. 9, the action point L, the force point E, and the fulcrum F of the switching member 165 are arranged in a substantially right-angled triangle shape, and the force point E and the fulcrum F of the switching member 165 are arranged along a direction orthogonal to the feeding direction of the bolt B, and are located on the front side in the feeding direction of the bolt B from the action point L, and the head passing portion 167 and the action point L are located on the rear side in the feeding direction of the bolt B from the force point E and the fulcrum F of the switching member 165. Thus, it contributes to reducing the operating area of the switching member 165.

[0057] Also, it can be said that the main body member 150 is composed of a base plate 151, a main body 153, a sub-plate 156, and an upper plate 158.

[0058] The periphery of the end portion on the blanking means side of the chute 130 including the locking portion 166 of the switching member 165 and the sub-plate 156 is a standby portion 120 where the bolt B waits.

[0059] The component supply pipe 180 is made of metal and is formed in a cylindrical shape having an insertion hole 180a. At the upper end portion, it is fitted into and attached to the insertion hole 152 of the base plate 151.

[0060] The component supply pipe 180 is connected to the component supply unit 30 via the chute hose 31.

[0061] Next, the operation of the blanking device 100 will be described.

[0062] In FIG. 9, the switching member 165 is at the component receiving position, and three bolts B are waiting in the standby portion 120. The leading bolt B is locked in a state where the head B1 is placed on the locking portion 166 of the switching member 165 as shown in FIGS. 7 and 8.

[0063] In this state, the head B1 of the bolt B on the rear side in the feeding direction rides on the upper side of the head B1 of the bolt B located on the front side. Furthermore, since the rearmost bolt B is not detected by the proximity sensor 134, the bolt B is in a state of being sent from the supply device 40.

[0064] From this state, the air cylinder 161 is driven to rotate the switching member 165.

[0065] By the rotation of the switching member 165, as shown in FIGS. 10 and 11, the bolt B moves forward in the bolt B feeding direction from the locking portion 166 through the passage portion 168. As shown in FIG. 12, when the bolt B reaches the head passing portion 167, it passes through the passage hole 153b of the main body 153 communicating with the head passing portion 167, falls into the insertion hole 180a of the component supply pipe 180, and is sent to the component supply unit 30 through the shoot hose 31 by the pressure feeding of the air from the air joint 159.

[0066] Specifically, the entry portion 170 enters between the shaft portion B2 of the bolt B located at the very front of the standby portion 120 and the shaft portion B2 of the bolt B located one position rearward in the feeding direction from the said bolt B. And the restricting portion 171 abuts against the shaft portion B2 of the bolt B to restrict the bolt B from being sent to the component supply pipe 180.

[0067] At this time, since the air cylinder 161 is pivotally supported by the pivot support bracket 163, it can follow the rotation of the switching member 165.

[0068] When the bolt B separates from the switching member 165, the switching member 165 is rotated in the reverse direction by the drive of the air cylinder 161 and returns to the original position. The bolt B in the standby portion 120 slides obliquely downward by one position, the leading bolt B is locked at the locking portion 166 of the switching member 165, and when the rearmost bolt B is no longer detected by the proximity sensor 134, the bolt B is fed from the supply device 40 to the standby portion 120 via the guide chute 200.

[0069] When the proximity sensor 134 detects the bolt B, the supply device 40 stops feeding the bolt B.

[0070] The blanking device 100 with the above configuration includes a chute 130 through which a bolt B as a component having a head B1 and a shaft portion B2 extending from the head B1 and formed with a smaller diameter than the head B1 is fed. A blanking means 140 arranged on the front side in the feeding direction of the bolt B in the chute 130 for separating the bolts B one by one. A component supply pipe 180 through which the bolts B separated by the blanking means 140 flow. and is provided with A standby portion 120 where a plurality of bolts B wait is arranged around the end portion on the blanking means 140 side of the chute 130. The blanking means 140 includes a main body member 150, a switching member 165 that is rotatable with respect to the main body member 150 and switches the passage and stop of the bolt B, and an air cylinder 161 as a first driving device for driving the switching member 165. The switching member 165 has a locking portion 166 capable of locking the bolt B, a head passing portion 167 through which the head B1 can pass, and a passage portion 168 communicating the locking portion 166 and the head passing portion 167. It is rotatable between a component receiving position where the bolt B located at the frontmost of the standby portion 120 is received by the locking portion 166 and a component feeding position where the component supply pipe 180 and the head passing portion 167 are in communication and the bolt B can be fed.

[0071] According to this, by adopting a configuration in which the switching member 165 is rotated by the air cylinder 161, the number of components can be reduced and a simpler configuration can be achieved, so that the installation space can be reduced.

[0072] Also, the switching member 165 has an entering portion 170 that can enter between the shaft portion B2 of the bolt B located at the frontmost of the standby portion 120 and the shaft portion B2 of the bolt B located one position rearward in the feeding direction from the bolt B. It is disposed on a part of the entrance portion 170, formed as an arc surface concentric with the rotation axis of the switching member 165, and abuts on the shaft portion B2 of the bolt B located one feed direction rearward from the bolt B to regulate the supply to the component supply pipe 180. A regulating portion 171; is provided.

[0073] According to this, the entrance portion 170 enters between the shaft portion B2 of the bolt B located at the very front of the standby portion 120 and the shaft portion B2 of the bolt B located one feed direction rearward from the bolt B. Then, the regulating portion 171 regulates the supply of the bolt B to the component supply pipe 180, thereby preventing a problem with the feeding of the bolt B due to component jamming.

[0074] Further, when the switching member 165 is at the component receiving position, the action point L, the force point E, and the fulcrum F of the switching member 165 are arranged in a substantially right-angled triangle shape. The force point E and the fulcrum F of the switching member 165 are arranged along a direction orthogonal to the feeding direction of the bolt B, and are located on the front side in the feeding direction of the bolt B from the action point L. The head passing portion 167 and the action point L are located on the rear side in the feeding direction of the bolt B from the force point E and the fulcrum F of the switching member 165.

[0075] According to this, it contributes to reducing the operating area of the switching member 165.

[0076] The blanking device of the present invention is not limited to the above configuration. That is, various design changes and the like are possible without departing from the gist of the present invention.

[0077] For example, the arrangement, shape, etc. of each component of the blanking means 140 can be appropriately changed according to the usage mode.

[0078] Also, as long as the component has a head and a shaft portion, other components than bolts can be applied.
