Then, when the bracket 71 holds the spatula body 80, as shown in FIG. 6, the bracket 71 is configured to scrape off the deposits on the blade body 81 of the spatula body 80 inserted between the left and right rubbing blades 51 and 51. are doing.

Next, the operation of removing the sealer will be specifically described.
FIG. 9A shows a state in which the spatula support 82 is attached to the bracket 71 in a state where the elevating plate 200 rises due to the extension of the cylinder 11 to reach top dead center and the rubbing blades 51 and 51 are most separated from each other. It is a figure. That is, it is a state diagram before inserting the blade 81 between the rubbing blades 51 and 51 and sandwiching the blade 81.

First, the operation leading to the initial state shown in FIG. 9A will be described. As the cylinder 11 extends, the front-rear frame bodies 43 and 44 mounted on the elevating plate 200 rise. Along with this, the camshafts 54 and 54 move away from each other while rising through the left and right guide vertically elongated holes 22 and 22.

That is, since the left and right guide vertical holes 22 and 22 gradually widen the left and right intervals from the lower side to the upper side, 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. The shafts 54, 54 are separated from each other via the sliders 56, 56 as the elevating plate 200 is raised, and the brackets 52, 52 interlocked with the shafts 54, 52 are separated from each other, whereby the left and right rubbing blades 51, 51 also operates apart.

When the elevating plate 200 continues to ascend and reaches the top dead center, the ascent stops, and at this time, the left and right rubbing blades 51 and 51 are most separated from each other. In this state, the blade 81 of the spatula body 80 is inserted between the left and right rubbing blades 51 and 51, and is attached to the bracket 71. As a result, the deposits adhering to the blade 81 are scraped off.

Next, as shown in FIG. 9B, when the elevating plate 200 starts to descend due to the contraction of the cylinder 11, the camshafts 54 and 54 have the left and right guide vertically elongated holes 22 and 22 due to the descending operation of the elevating plate 200. Through, it descends along the shape. The left and right guide vertically elongated holes 22 and 22 are formed so that the distance between the left and right guide vertically elongated holes 22 and 22 becomes narrower from the upper part to the lower side, and the gradual curve becomes a gentle proximity shape toward the inward side. Therefore, as the elevating plate 200 descends, it first operates rapidly in close proximity, and then gradually and slowly operates in close proximity.

When the camshafts 54 and 54 are close to each other, the brackets 52 and 52 interlocked with the camshafts 54 and 54 are brought close to each other by sliding the sliders 56 and 56, and the blade support plates 50 and 50 connected to the brackets 52 and 52 are brought close to each other. The rubbing blades 51 and 51 that are close to each other and supported by the rubbing blades 51 and 51 are close to each other. Since the curve is largely curved inward at the upper part of the left and right guide vertically elongated holes 22, the left and right rubbing blades 51, 51 rapidly approach each other in conjunction with this, and sandwich the blade body 81.

Then, as the camshafts 54 and 54 descend, the left and right rubbing blades 51 and 51 approach each other along the curves of the left and right guide vertically elongated holes 22 and 22, and the blades 81 adhere to each other while rubbing downward. Remove the sealer.

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

Next, as shown in FIG. 9D, when the elevating plate 200 reaches the bottom dead center, the descent ends there, and the camshafts 54, 54 inserted through the left and right guide vertical holes 22, 22 also die down. Reach the point. At this time, the left and right rubbing blades 51 and 51 interlocking with the blades 51 and 51 are closest to each other, and the operation of removing the adhered sealer is stopped 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 is discharged via the sealer discharge pipe 35 provided in the sealer recovery box 34 and the sealer discharge tube 36 connected thereto. , The sealer removal process is completed.

As described above, the camshafts 54 and 54 descend via the left and right guide vertically elongated holes 22 and 22 as the elevating plate 200 descends, and the brackets 52 and 52 interlocked with the camshafts 52 and 52 are slidders 56. , 56 to approach. As a result, the blade support plates 50, 50 connected to the brackets 52, 52 are close to each other, and the rubbing blades 51, 51 supported by the blade support plates 50, 50 are close to each other. Then, the left and right rubbing blades 51, 51 can remove the attached sealer while sandwiching 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 expands and the elevating plate 200 rises, and the front-rear frame bodies 43 and 44 rise in conjunction with this. The left and right camshafts 54, 54 rise through the left and right guide vertical holes 22, 22, and the brackets 52, 52 are interposed through the left and right brackets 52, 52 and the sliders 56, 56, which are interlocked with the left and right camshafts 54, 52. When the blade support plates 50, 50 serially connected to the blade support plates 50, 50 are separated from each other, the left and right rubbing blades 51, 51 supported by the blade support plates 50, 50 are separated from each other and rise.

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

As described above, by using the spatula body adhering sealer removing device 1 according to the first embodiment, the time required for removing the spatula body adhering sealer can be shortened and automated, and the work can be applied to the work which is the original work. The work of removing the sealer adhering to the spatula, which was included in the work of leveling the sealer and removing the excess, is a separate process and is separated and excluded from the tact time of the original work, thus shortening the tact time of the original work. It has the effect of improving productivity and reducing costs.
