  The article adsorbing and conveying apparatus 100 shown in FIG. 1 is provided with the article adsorbing tool 1 of the present invention on a support bar 103 attached to a feed bar 101 via an attaching tool 102. In this embodiment, two support bars 103 are attached to one feed bar 101, and the rectangular shape (oval shape, oval shape, etc.) of the suction member 30 of one article suction tool 1 provided on one support bar 103 is used. The narrow portion of the workpiece W is sucked by the suction surface 30R, and the wide portion of the workpiece W is sucked by the circular suction surface 30C of the suction member 30 of the other article suction tool 1 provided on the other support bar 103. I am going to do it.

  As shown in FIGS. 2 and 3, the article adsorbing tool 1 is configured by supporting a supported portion 40 of an adsorption member 30 on a universal joint 20 that can be tilted with respect to a support member 100 fixed to a support bar 103. .

  The support member 10 is fixed to the support bar 103 using U-shaped bolts 11. The support member 10 is provided with two split sandwiching means 12, 12. The universal joint 20 is sandwiched and fixed between the sandwiching means 12, 12 fastened by bolts and nuts 13.

  The universal joint 20 includes a female member (outer ring) 21 (FIG. 5) and a male member (inner ring) 22 that are spherically fitted. The female member 21 is composed of two arc-shaped parts divided into two in the circumferential direction, and has two slit parts 21A formed at both ends in the circumferential direction of the arc-shaped parts. However, the female member 21 may have a C-shaped ring shape and may have one slit portion 21A only at one place in the circumferential direction. The male member 22 includes a spherical outer peripheral surface that can be spherically fitted to the spherical inner peripheral surfaces of the two arc-shaped parts of the female member 21, and constitutes an annular part built in the female member 21, and the annular part. The supported portion 40 of the suction member 30 is inserted into a guide hole 22A provided at the center of the suction member 30 as will be described later. The female member 21 is fitted into a hole-shaped loading portion 12 </ b> A formed in the sandwiching means 12, 12 of the support member 10 in the assembled state in which the male member 22 is incorporated, and is retained by the C-shaped retaining ring 14. .

  The universal joint 20 has a spherical shape of the male member 22 with respect to the spherical inner peripheral surface of the female member 21 in a loosened state of the bolt and nut 13 in which the slit portion 21A of the female member 21 is not sandwiched by the clamping means 12 and 12 of the support member 10. The outer peripheral surface is brought into sliding contact so that the male member 22 can tilt with respect to the female member 21. As a result, the mounting angle formed by the suction surface 30A of the suction member 30 in which the supported portion 40 is inserted into the guide hole 22A of the male member 22 with respect to the support member 10 that holds the female member 21 so as to prevent the universal member 30 from being removed. Can be adjusted by the above-mentioned tilting. The entire surface of the suction surface 30A of the suction member 30 can be made to follow the curved surface, slope, or the like of the attracted portion of the workpiece W. The attachment angle θ of the suction surface 30A of the suction member 30 with respect to the vertical support shaft C of the support member 10 changes as the universal joint 20 is tilted as described above. The suction surface 30A shown in FIG. 3 is in a state where the mounting angle θ = 0 degrees.

  On the other hand, the universal joint 20 is configured such that the male member 22 is opposed to the spherical inner peripheral surface of the female member 21 in a fastening state of the bolt and the nut 13 that sandwich the slit portion 21A of the female member 21 by the sandwiching means 12 and 12 of the support member 10. The spherical outer peripheral surfaces are solidly fixed together, and the male member 22 is tilt-locked with respect to the female member 21. With the universal joint 20 tilted and locked in this manner, the supported portion 40 of the suction member 30 is only in one direction (the axial direction of the guide hole 22A) with respect to the guide hole 22A of the male member 22 in the universal joint 20. It is supported so that it can move linearly. At this time, the supported portion 40 of the attracting member 30 is slidably inserted into the guide hole 22A of the male member 22 in the universal joint 20 in a detent state by the detent means 50. Specifically, the rotation preventing means 50 includes two pins 51 provided on the same diameter of the guide hole 22 </ b> A of the male member 22 in the universal joint 20, which are described later in the supported portion 40 of the suction member 30. It is configured by being slidably engaged with a rotation-preventing groove 52 provided along the axial direction of the outer periphery.

  As shown in FIG. 4, the supported portion 40 of the adsorption member 30 has a hollow rod shape, the shaft portion 41 is inserted into the guide hole 22 </ b> A of the male member 22 in the universal joint 20, and the upper end boss portion 42 of the shaft portion 41 is connected to the male portion. The suction member 30 is fixedly attached to the lower end attachment portion 43 of the shaft portion 41 while abutting against the upper end surface of the member 22. In this embodiment, a resilient means 60 made of, for example, a coil spring is interposed between the lower end surface of the male member 22 and the upper end surface of the suction member 30 around the shaft portion 41 of the supported portion 40, and the suction member 30. The supported portion 40 is urged in a direction protruding from the universal joint 20. The suction member 30 compresses the elastic means 60 so that the supported portion 40 can move in the aforementioned axial direction with respect to the guide hole 22A of the male member 22 in the universal joint 20 by the maximum stroke St (FIG. 3).

  The suction member 30 is formed of a vacuum cup in this embodiment, and exerts a vacuum suction force supplied by a vacuum pipe connected to the upper end boss portion 42 of the supported portion 40 on the suction surface 30A so that the workpiece W can be sucked. . 1, the suction surface 30A of the suction member 30 in one article suction tool 1 has a rectangular suction surface 30R, and the suction member 30 in the other article suction tool 1 is suctioned. The surface 30A has a circular suction surface 30C.

Hereinafter, the operation of the article adsorption transport device 100 will be described.
(1) The support members 10 of the two article adsorbing tools 1 are fixed to the two support bars 103 attached to the feed bar 101, respectively.

  (2) In each article adsorbing tool 1, the male member 22 can be tilted with respect to the female member 21 of the universal joint 20 with the bolts and nuts 13 loosened, and the adsorption surface 30 </ b> A (30 </ b> R or 30 </ b> R or 30C) can be made to follow the corresponding attracted portion of the workpiece W.

  (3) By moving the feed bar 101, the suction surface 30 </ b> A (30 </ b> R or 30 </ b> C) of the suction member 30 included in each article suction tool 1 is brought into pressure contact with the corresponding suction target portion of the workpiece W to suck the workpiece W. The rectangular suction surface 30 </ b> R of the suction member 30 in one article suction tool 1 reliably sucks the narrow part without rotationally deviating from the proper suction posture with respect to the narrow part of the work W. The large-diameter circular suction surface 30 </ b> C of the suction member 30 in the other article suction tool 1 strongly suctions the wide portion of the workpiece W. When the suction surface 30A of the suction member 30 is in pressure contact with the workpiece W, the suction member 30 moves the supported portion 40 within the range of the maximum stroke St while elastically deforming the elastic means 60 to absorb the pressure contact force. The deformation of the workpiece W is prevented.

  (4) By moving the feed bar 101, the workpiece W attracted by the suction surface 30A (30R or 30C) of the suction member 30 provided in each article suction tool 1 is transferred to the destination. At the time of transfer to the delivery destination, the suction member 30 of each article suction tool 1 can be transferred without shifting the workpiece W with respect to the workpiece placement platform of the delivery destination and without dropping it. Release the vacuum suction force to complete the transfer of the workpiece W. At this time, since the suction member 30 is backed up by the elastic means 60, the suction member 30 can be moved away in the axial direction so as not to apply an excessive pressure to the workpiece W.

According to the present embodiment, the following operational effects can be obtained.
(a) The attachment angle θ formed by the suction surface 30A of the suction member 30 with respect to the support member 10 can be adjusted by tilting the universal joint 20 and can be fixed by tilting lock of the universal joint 20. Accordingly, when the workpiece W is sucked by the article suction tool 1, the entire suction surface 30A of the suction member 30 can be made to follow the curved surface, the slope, or the like of the suctioned portion of the workpiece W, thereby ensuring the suction.

  (b) Under the state where the universal joint 20 is tilt-locked, the supported portion 40 of the adsorption member 30 is supported so as to be linearly movable in only one direction with respect to the universal joint 20. Thereby, in the article | item adsorption | suction tool 1 which makes it possible to fix the attachment angle (theta) of the adsorption member 30 with the tilt lock of the universal joint 20, it can move to an axial direction, preventing the adsorption member 30 from rotating. Therefore, when the suction surface 30A of the suction member 30 comes into pressure contact with the workpiece W in order to suck the workpiece W, the suction member 30 does not move in the axial direction, and the workpiece W is not excessively pressed and deformed. . At the same time, even when the suction member 30 is not freely pivoted and the suction surface 30A of the suction member 30 has a rectangular shape or the like, the suction posture of the suction surface 30A with respect to the workpiece W is rotationally shifted from the proper posture. In other words, the suctioned surface 30A that is out of rotation does not completely catch the part to be sucked of the work W, and there is no such thing as causing suction failure.

  (c) A resilient means 60 for urging the supported portion 40 of the suction member 30 in a direction protruding from the universal joint 20 is provided. The adsorbing member 30 adsorbs the workpiece W while escaping while being pressed against the workpiece W with a constant contact force by the urging force of the elastic means 60, and is restored to a predetermined initial position after the adsorption.

  (d) The universal joint 20 is composed of a female member 21 and a male member 22 which are fitted into a spherical surface, and a sandwiching portion 21A provided in a part of the circumferential direction of the female member 21 is sandwiched by sandwiching means 12 and 12, The universal joint 20 is tilt-locked easily and reliably.

  (e) The supported portion 40 of the adsorption member 30 is inserted into the guide hole 22A of the universal joint 20 so as to be slidable in a non-rotating state by the anti-rotation means 50, and the adsorption member 30 is inserted into the universal joint 20. Make sure that it can move linearly in only one direction.

  (f) The detent means 50 slidably engages a pin 51 provided in one of the supported portion 40 of the adsorption member 30 and the guide hole 22A of the universal joint 20 in a detent groove 52 provided in the other. Then, the adsorption member 30 can be linearly moved only in one direction with respect to the universal joint 20 in a simple and reliable manner.

  (g) Even when the suction surface 30R of the suction member 30 has a rectangular shape, the suction member 30 is prevented from rotating, and the suction posture of the suction surface 30R with respect to the workpiece W does not rotationally deviate from the proper posture. The suction surface 30R that has been rotationally displaced does not completely capture the portion to be attracted of the workpiece W, and there is no possibility of causing a suction failure.

  In addition, by forming the long suction surface 30 </ b> R with respect to the narrow portion of the work W, a necessary and sufficient suction force is imparted to the work W. Therefore, the workpiece W can be reliably sucked only by the single suction member 30, and the position shift of the workpiece W due to vibration or the like does not occur.

  The article adsorbing tool 1 shown in FIGS. 7 to 9 is different from the article adsorbing tool 1 shown in FIGS. 1 to 6 in that the supported portion 40 of the adsorbing member 30 is straight in only one direction with respect to the universal joint 20. The anti-rotation means 70 is used instead of the anti-rotation means 50 that is movably supported. The anti-rotation means 70 includes a non-circular cross section of the adsorbing member 30, in this embodiment, the outer peripheral surface of the supported portion 40 having a hexagonal cross section, and a noncircular shape of the male member 22 in the universal joint 20. The reason is that the hole 22A is slidably inserted.

  The article adsorbing tool 1 shown in FIGS. 7 to 9 has the same effects as the article adsorbing tool 1 shown in FIGS. 1 to 6.

  The article adsorbing tool 1 shown in FIGS. 10 and 11 is different from the article adsorbing tool 1 shown in FIGS. 1 to 6 in that the supported portion 40 of the adsorbing member 30 is straight in only one direction with respect to the universal joint 20. The anti-rotation means 80 is used instead of the anti-rotation means 50 that is movably supported. The rotation preventing means 80 is provided with a flat portion 81 (in this embodiment, a hexagonal cross-section outer peripheral surface) provided in the outer periphery of the supported portion 40 of the adsorption member 30 in the guide hole 22A of the male member 22 in the universal joint 20. The pin 82 is slidably contacted. In this embodiment, two pins 82 are provided on the same diameter of the guide hole 22A of the male member 22.

  Even in the article adsorbing tool 1 shown in FIGS. 10 and 11, the same effects as the article adsorbing tool 1 shown in FIGS.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration of the present invention is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention. Included in the present invention. For example, the adsorbing member of the article adsorbing tool may adsorb the workpiece W by a magnetic attractive force such as an electromagnet.

  According to the present invention, in the article adsorbing tool that can fix the attachment angle of the adsorption member by the tilt lock of the universal joint, the adsorption member can be moved in the axial direction while preventing the adsorption member from rotating.
