Next, the operation of removing the sealer will be specifically described.
FIG. 9A shows a state in which the spatula support 82 is mounted on the bracket 71 in a state where the elevating plate 200 rises due to the extension of the cylinder 11 and reaches the top dead center, and the rubbing blades 51 and 51 are most separated. FIG. That is, it is a state diagram before the blade body 81 is inserted between the rubbing blades 51 and 51 and sandwiched therebetween.

  First, the operation leading to the initial state shown in FIG. 9A will be described. The front and rear form bodies 43 and 44 mounted on the elevating plate 200 are raised by the extension of the cylinder 11. Along with this, the camshafts 54, 54 are lifted and separated from each other via the left and right guide vertical holes 22, 22.

  That is, since the left and right guide vertical holes 22 and 22 are formed such that the left and right intervals are gradually widened from below to above, the left and right cams inserted into the left and right guide vertical holes 22 and 22 of the cam guide plates 21 and 21 are formed. The shafts 54, 54 move away from each other via the sliders 56, 56 in accordance with the raising operation of the lifting plate 200, and the brackets 52, 52 provided in conjunction therewith operate to move away from each other, so that the left and right rubbing blades 51, 51 also moves away.

  When the elevating plate 200 continues to ascend and reaches the top dead center, the ascent is stopped, and at this time, the left and right rubbing blades 51 are most separated. In this state, the blade body 81 of the spatula body 80 is inserted between the left and right rubbing blades 51, 51 and attached to the bracket 71. As described above, the adhered matter adhered to the blade body 81 is rubbed off.

  Next, as shown in FIG. 9 (b), when the lifting plate 200 starts lowering due to the contraction of the cylinder 11, the camshafts 54, 54 move the left and right guide vertical holes 22, 22 by the lowering operation of the lifting plate 200. And descends along the shape. The left and right guide vertically elongated holes 22, 22 are formed so that the interval between them becomes narrower from the upper side to the lower side, and the shape gradually becomes closer to the inside, so that the curve gradually becomes closer. For this reason, as the elevating plate 200 descends, the proximity operation is rapidly performed at first, and then the operation is gradually and gradually performed.

  When the camshafts 54, 54 come close to each other, the brackets 52, 52 interlockingly connected thereto come close to each other by sliding of the sliders 56, 56, and the blade supporting plates 50, 50 connected to the brackets 52, 52 move. The rubbing blades 51, 51 supported by this approach and approach. In the upper part of the left and right guide vertically elongated holes 22, the curve is largely curved inward, so that the left and right rubbing blades 51, 51 rapidly approach and interpose the blade body 81.

  Then, as the camshafts 54, 54 descend, the left and right rubbing blades 51, 51 approach along the curves of the left and right guide vertical holes 22, 22, and adhere while rubbing the blade body 81 downward. Remove the sheila.

  Next, as shown in FIG. 9C, when the elevating plate 200 is further lowered, the camshafts 54 are further lowered via the left and right guide vertical holes 22, 22. At this position, since the curves of the left and right guide vertically elongated holes 22 and 22 are gentle, the left and right rubbing blades 51 and 51 gradually gradually approach and remove the adhered sealer while rubbing the blade body 81 downward. I will do it.

  Next, as shown in FIG. 9D, when the elevating plate 200 reaches the bottom dead center, the descent is finished there, and the camshafts 54, 54 inserted into the left and right guide vertical holes 22, 22 are also bottom dead. Reach the point. At this time, the left and right rubbing blades 51, 51 interlocking with this, are closest to each other, and stop the operation of removing the adhered sealer while rubbing the blade body 81.

  Further, the scraped sealer is sucked into the sealer collection box 34 from the sealer collection port 33, and discharged through the sealer discharge pipe 35 provided in the sealer collection box 34 and the sealer discharge tube 36 connected thereto. Then, the sealer removing step ends.

  As described above, as the elevating plate 200 descends, the camshafts 54, 54 descend through the left and right guide vertical holes 22, 22, and the brackets 52, 52 interlockingly connected to the camshafts 54, 52 slide. , 56. As a result, the blade support plates 50, 50 connected to the brackets 52, 52 come close to each other, and the rubbing blades 51, 51 supported by this come close to each other. Then, the left and right rubbing blades 51, 51 can remove the adhered sealer while holding the blade body 81 and rubbing downward.

  When the removal of the sealer is completed and the spatula body 80 is removed from the bracket 71, the cylinder 11 is extended and the elevating plate 200 is raised, and the front and rear frame members 43 and 44 are raised as described above. The left and right camshafts 54, 54 rise through the left and right guide vertical holes 22, 22, and the brackets 52, 52 via the left and right brackets 52, 52 and The left and right rubbing blades 51, 51 supported by the blade support plates 50, 50 are lifted while separating from each other.

  When the elevating plate 200 reaches the top dead center, the left and right camshafts 54, 54 also stop rising, and the left and right rubbing blades 51, 51 interlocking with this, are most separated. Then, the bracket 71 is in a state where the next spatula body 80 can be mounted, and a series of operations is completed.

  As described above, by using the spatula body-attached sealer removing apparatus 1 according to the first embodiment, it is possible to shorten the time required for the work of removing the spatula body-attached sealer and to automate the work, and to apply the spatula body to the work that is the original work. The work for removing the sealer attached to the spatula body, which was included in the work for removing the sealer leveling and excess, is a separate process and is separated and excluded from the original work takt time, thus shortening the original work takt time. This has the effect of improving productivity and reducing costs.

  Next, a second embodiment of the present invention will be described. As shown in FIG. 12, the spatula body-attached sealer removing device 2 according to the second embodiment of the present invention uses a metal support plate 65 provided on the top of the body frame 60 shown in FIG.

  On the turntable 70, as shown in FIG. 12, four brackets 71 are arranged orthogonally as stations st1 to st4. Further, the spatula body-attached sealer removing device 1 is provided at a station st2.

  Next, the operation of the turntable 70 will be described. As shown in FIG. 12, a worker or a mounting and removing device such as a robot (not shown) mounts the spatula body 80 to the bracket 71 of the station st1. When the mounting is completed, the turntable 70 rotates 90 degrees in the counterclockwise direction, and the spatula body 80 reaches the spatula body-attached sealer removal device 1 provided at the station st2.

  The blade body 81 of the spatula body 80 stops between the rubbing blades 51 at the top dead center of the spatula body attached sealer removing device 1. When the arrival of the spatula body 80 is detected, the cylinder 11 starts contracting, and the rod 11a contracts. As a result, the lifting plate 200 starts to descend. Hereinafter, as described in FIG. 9, the rubbing blades 51 remove the sealer attached to the blade body 81.

  When the removal of the sealer is completed, the turntable 70 rotates 90 degrees counterclockwise, and the spatula body 80 reaches the station st3. The station st3 is a preliminary step, but another stationer-body-attached sealer removing device 1 is provided in this station st3, and the sealer is removed using two spatula-body-attached sealer removing devices 1. You may comprise. That is, the station st2 can be a roughing step and the station st3 can be a finishing step.

  In this case, the operation of removing the sealer by the rubbing blades 51, 51 of the spatula body-attached sealer removing device 1 at the station st3 is the same as the operation at the station st2, and thus the description is omitted.

  When the work in the station st3 is completed, the turntable 70 rotates 90 degrees counterclockwise, and the spatula body 80 reaches the station st4. Station st4 is an inspection process.

  An inspection camera 77 is installed in the station st4, an image of the spatula body 80 is taken, and the image data is sent to an inspection device 78 connected to the inspection camera 77. The inspection device 78 inspects a predetermined inspection item based on the image.

  The inspection items include, for example, the presence or absence of unevenness of the spatula support 82 and the blade body 81, the presence or absence of the color and pattern of the surface of the spatula support 82 and particularly the blade body 81, and the like. to decide. In addition, the spatula support body 82 and the blade body 81 are also inspected for a worn state or a scratch due to long-term use.

  If there is no abnormality, the screen of the inspection device 78 is displayed as a non-defective product, and a green lamp (not shown) is turned on to notify the operator of the non-defective product.

  If there is an abnormality, a message indicating that the product is defective is displayed on the screen of the inspection device 78 as a defective product, a red lamp (not shown) is lit, and an alarm is sounded to inform the worker that the product is defective. Close. Further, the operation of the present apparatus 2 is stopped, and the worker removes the spatula body 80 of the defective product, goes to a repair work process, and mounts a substitute product of a good product on the bracket 71 of the station st4 instead of the defective product. . Of course, a configuration may be adopted in which the removal and mounting of the defective product is performed by a mounting and removing device (not shown) instead of the worker.

  In the step of the station st4, if the spatula body 80 is a good product or if it is a defective product and the treatment is completed, the turntable 70 is rotated 90 degrees counterclockwise, and the spatula body 80 Return to st1. Then, at the station st1, the worker or a mounting and removing device (not shown) removes the non-defective spatula body 80 from the bracket 71 and mounts the spatula body 80 for removing the next sealer on the bracket 71.

  As described above, by the series of operations of the turntable 70, the used spatula body 80 is merely mounted on the bracket 71, and thereafter the turntable 70 is automatically rotated and the spatula body attached sealer is removed.
