Description

  The present invention relates to a method for replacing a window glass of an automobile.

  The window glass of an automobile may break when the vehicle is traveling or stopped. Broken windows are replaced with new ones. At this time, the broken window glass is removed and replaced with a new window glass. The windshield of an automobile window glass is most easily broken. Unfortunately, the windshield is the largest and heaviest glass. In particular, the windshields of buses and trucks are extremely heavy, and the replacement work is extremely hard work. The largest and heaviest windshield is for tourist buses, and the main window glass is over 100kg.

  To replace the window glass of an automobile, a sucker is adsorbed on the surface of the window glass, and the operator holds the sucker by hand to remove the broken window glass and install a new window glass. This work is not only extremely hard work, but also moves heavy window glass, so that there are problems such as broken glass coming into contact with the automobile and scratching the body, and dropping new glass and breaking. For this reason, it is necessary to work very carefully, and there is a drawback that it takes a lot of time and effort. Further, since the window glass is extremely heavy, it is a fact that it is difficult to accurately set the window glass at a fixed position. In the automobile manufacturing process, the window glass can be set at a fixed position by using a robot, but since the removal and removal of the broken window glass is an on-site work, the robot cannot be used, and it is performed manually without exception. ing.

  Furthermore, a new window glass in an automobile is fixed in a watertight manner to the window frame of the automobile with an adhesive. In this method, an adhesive is applied to the peripheral edge of the window glass in advance, and the window glass is set at a fixed position. At this time, the operation of applying the adhesive to the window glass cannot be performed in the state where the window glass is erected. This is because the adhesive cannot be applied to the lower edge of the window glass. Therefore, it is necessary to arrange the window glass to which the adhesive is applied in a horizontal posture. However, if the window glass is placed on the upper surface of a table or the like in order to horizontally support the window glass of an automobile, the window glass has a curved shape and cannot be stably supported.

  For this reason, conventionally, for example, the window glass G is placed on a work table having the structure shown in FIG. 1, and the window glass G is horizontally supported by the work table, and an adhesive is applied to the peripheral portion. It was. The work table shown in this figure has a pair of X detachable work tables 91 that can be folded connected to each other at the opposite upper ends by a support pipe 92, and at the opposite lower ends by a connection pipe 93. The work table having this structure can be horizontally supported by placing the window glass G on the support pipes 92 on both sides with the X frame 91 opened. Further, the work table can be conveniently transported by folding the X frame 91 after work.

  However, since the support pipe directly contacts the window glass in the work table having this structure, there is a possibility that the window glass may be damaged at the contact portion. The support pipe can be covered with a buffer member, but it cannot completely eliminate the harmful effect of damaging the window glass. Further, when the support pipe comes into contact with the window glass, the window glass may be soiled. When a new window glass becomes dirty, it is necessary to remove the dirt, which increases the labor and the work efficiency.

  Further, since the curved shape and size of the window glass vary depending on the type of vehicle and the vehicle type, the window shown in the figure cannot stably support all the window glasses. A work table that cannot stably support the window glass is dangerous because the heavy window glass is tilted or wobbled during the work, and the work cannot be performed accurately. Furthermore, this work table also has a difficulty in moving the window glass after the work of applying the adhesive is finished. This is because it is necessary to adsorb the lower surface of the window glass with a suction cup and move the window glass with the suction cup by hand. In particular, since the window glass having an adhesive applied to the peripheral edge needs to move so as not to touch this part, this also makes the movement of the window glass difficult.

The present inventor has developed a workbench shown in FIG. 2 for the purpose of solving such drawbacks. (See Patent Document 1)
JP 2003-341486 A

  The work table shown in FIG. 2 includes a detachable work table connected to the window glass and a work table on which the window glass is placed horizontally by placing the detachable work table. The desorption work table connects the suction cups 40 that are adsorbed to the surface of the window glass G so as to be desorbed. The desorption work table is connected to the window glass by the suction cup 40, the desorption work table 50 is placed on the mounting table, and the window glass G is arranged horizontally. Using this workbench, windowpanes can be replaced conveniently and efficiently.

  Further, when the window glass is replaced using this work table, the window glass is covered with a plastic film and adsorbed with a suction cup through the plastic film, so that the window glass can be prevented from being stained and scratched. In this method, a plastic film is sandwiched between a suction cup and a window glass, and the suction cup is sandwiched between the window glass. The suction cup is directly adsorbed on the surface of the window glass.Dust and dust adhering to the surface of the window glass scratches the surface. Eliminate harmful effects. In addition, the method of covering the surface of the window glass with a plastic film prevents dust and dirt from adhering to the surface of the window glass. For this reason, it is possible to work while preventing the window glass surface from being damaged and further preventing the window glass surface from being stained.

  However, in the method of adsorbing the suction cup to the window glass through the plastic film, if foreign matter such as dust or soot enters between the plastic film and the window glass, the window glass cannot be firmly adsorbed by the suction cup. This is because the foreign matter that enters between the plastic film and the window glass creates a fine gap between the plastic film and the window glass, and this gap causes air leakage. The suction cup that is adsorbed to the window glass through the plastic film needs to be closely adhered to the surface of the window glass through the plastic film without any gap. If there is an air leak between the plastic film and the window glass, air is sucked into the suction cup from here and the suction cup cannot be held at a negative pressure, and the suction cup cannot be firmly adsorbed to the window glass. In particular, foreign matter that enters the inside of the plastic film cannot be easily taken out, and is difficult to shift from the suction position of the suction cup. If a slight gap appears here, the suction cup immediately after adsorbing is firmly adsorbed to the window glass, but due to air leakage from the gap, the degree of vacuum in the suction cup gradually decreases, and the suction force of the suction cup gradually decreases. . When the window glass is moved on the desorption work table in a state where the suction force of the suction cup is reduced, the window glass may come off from the desorption work table. Therefore, the method of adsorbing the suction cups to the window glass via the plastic film is difficult to work safely by firmly adsorbing the suction cups to the window glass even though the characteristics that can prevent the window glass by the plastic film can be realized. The evil can not be solved.

  Further, in the method of adsorbing the suction cups to the window glass with the plastic film interposed therebetween, the wrinkles of the plastic film cause air leakage. This is because if the suction cup adsorbs a wrinkled portion on the plastic film, a step is formed between the portion overlapped with the wrinkle and one portion, and this step causes air leakage. The plastic film that covers the surface of the window glass without being adhered is easily displaced relative to the window glass and can be locally wrinkled on the surface of the window glass. If the suction cup is adsorbed to the wrinkled portion, it will not be adsorbed firmly to the window glass. The sucker sucked in this state cannot be reliably sucked in the same manner as the sucker that sucks foreign matter inside the plastic film, and the suction force gradually decreases even in the sucked state.

  The present invention has been developed for the purpose of solving the above-mentioned drawbacks. An important object of the present invention is that in addition to being able to be attached to a vehicle while protecting the window glass with a plastic film, the replacement of the window glass of an automobile in which the sucker can firmly absorb the window glass through the plastic film and safely replace it. It is to provide a method.

The vehicle window glass replacement method of the present invention has the following configuration in order to achieve the above-described object.
The entire window glass for automobiles is coated with a plastic film in a non-adhering state on the surface of the window glass, and the suction cup is adsorbed with the plastic film sandwiched between the surface of the window glass coated with the plastic film. Then, with the suction step of connecting the desorption work table through this suction cup, and the state in which the plastic film is sandwiched between the window glass with the suction cup, the plastic film is cut and removed along the outer peripheral edge of the window glass. A cutting and attaching step in which the outer peripheral portion of the glass is exposed to the outside with a predetermined width, a peeling tape is attached along the cutting edge of the plastic film, and a non-adhesive plastic film is attached to the window glass with the peeling tape; In the state where the plastic film is attached to the window glass with the peeling tape, And peeling the peeling tape from the window glass mounted on the automobile, the plastic film of non-adhesive state can be provided with a removal step of removing from the window glass.

  In the cutting and attaching step, the plastic film covering both sides of the window glass is removed by cutting along the outer peripheral edge of the window glass, and a peeling tape is attached along the cutting edge to remove the plastic film from the window glass. Can adhere to both sides.

  Further, the plastic film can be a flexible film having a thickness of 10 μm to 200 μm.

  Furthermore, in the adsorption process, three or more suction cups can be adsorbed to the window glass, and the desorption work table can be attached to the window glass.

  The window glass replacement method of the present invention can be attached to an automobile while protecting the window glass with a plastic film. In addition, the window glass can be securely attached by sucking the suction glass firmly and sandwiching the plastic film. There are features that can be replaced. That is, the method of replacing the window glass of the automobile of the present invention covers the entire window glass of the automobile with the plastic film in a non-adhering state on the surface of the window glass, and then adsorbs the sucker so as to sandwich the plastic film. In this state, the plastic film is cut and removed along the outer peripheral edge of the window glass so that the outer periphery of the window glass is exposed to the outside, and further the release tape is applied along the cutting edge. This is because the plastic film is adhered to the window glass with the release tape, and the window glass is attached to the window of the automobile in this state, and the release tape and the plastic film are removed from the window glass in the state of being attached to the automobile.

  In particular, the window glass replacement method of the present invention cuts the plastic film so as to expose the window glass along the outer periphery of the window glass, and then attaches a release tape along the cutting edge, so that the release tape is cut. The sucker is adsorbed to the window glass from the surface of the plastic film in a state where the outer peripheral edge of the plastic film is in close contact with the window glass. This state prevents foreign substances such as dust and soot from entering the inside of the plastic film, that is, between the plastic film and the window glass, with the release tape. For this reason, the plastic film whose surface is adsorbed by the suction cup can be firmly adsorbed to the window glass in a state where the plastic film is adsorbed without a foreign substance that worsens the suction of the suction cup from entering inside.

  Furthermore, in the method for replacing a window glass of an automobile according to the present invention, a plastic film covering the window glass is adsorbed to a suction cup in a state where a peeling tape is attached to the periphery. The plastic film having the outer peripheral edge attached to the window glass with the release tape can be attached to the window glass with the release tape in a state where wrinkles cannot be formed. For this reason, the plastic film is wrinkled, and the disadvantage that the suction cup cannot be firmly adsorbed can be solved. The suction cup can be firmly adsorbed to the window glass and the heavy window glass can be safely attached to the automobile.

  Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment shown below exemplifies a method for replacing the window glass of an automobile for embodying the technical idea of the present invention, and the present invention replaces the method for replacing the window glass of the automobile with the following. Not specified.

  Further, in this specification, in order to facilitate understanding of the scope of claims, numbers corresponding to the members shown in the examples are indicated in the “claims” and “means for solving problems” sections. It is added to the members. However, the members shown in the claims are not limited to the members in the embodiments.

(Plastic film coating process)
The glass G shown in FIG. 2 is a window glass for automobiles. The entire surface of the glass G is covered with a plastic film P. Thereby, contamination and damage of the glass G can be prevented.

  The plastic film P must be coated on the surface of the glass G so that foreign matter such as dust or dust or air does not enter between the glass G and the plastic film P. This is because when these foreign substances and air are mixed, a fine gap is formed between the plastic film P and the glass G, and this gap causes air leakage. As a result, the plastic film P is easily peeled off from the glass G. Further, as described above, the degree of adhesion between the suction cup to be sucked and the plastic film P is lowered. Therefore, the plastic film P and the glass G are brought into close contact so that no gap is generated. Further, the plastic film P is covered with the glass G in a non-bonded state. The non-adhered state referred to here is a state where the adhesive is not adhered. By not using the adhesive, it is not necessary to wipe off the adhesive in a subsequent process, and the work burden can be reduced. Moreover, peeling of the plastic film P caused by uneven application of the adhesive can be prevented.

  Specifically, when the glass film G is coated with the plastic film P, care is taken so that air and foreign matter do not enter the inside of the plastic film P. In addition, the plastic film P is brought into close contact with the glass G so as not to be wrinkled.

  The plastic film P is a thin film having a thickness of 0.2 mm or less that is widely extended in two dimensions. More preferably, the thickness is 10 μm to 200 μm. The plastic film P preferably has a desired degree of tension and does not easily wrinkle, and is more flexible and can follow the curved surface shape of glass. This increases the degree of adhesion between the plastic film P and the glass G.

  If it is the plastic film P which has the above effects, the raw material etc. will not be specifically limited, For example, it is excellent in transparency, impact resistance, intensity | strength, and although it is an inexpensive polyethylene film and an ultrathin film, it is in strength. Excellent high density polyethylene film is available. Furthermore, a thin film made of polyvinyl chloride having excellent water resistance and strength can be substituted. Furthermore, the polyolefin copolymer film has stretchability, high strength, excellent gas barrier properties (property of preventing gas permeation), and high safety. In addition, as the plastic film P, polyvinylidene chloride film polypropylene film, nylon film, polyester film, fluororesin film, polyimide (polyamideimide) each having features in chemical resistance, water resistance, heat resistance, electrical characteristics, weather resistance, etc. ) Films are listed.

(Suction process: sucker)
The work table shown in FIGS. 2 to 3 includes a plurality of suction cups 40 that are sucked so as to be attached to and detached from the glass G through a plastic film P, a removal work table 50 that connects these suction cups 40, And a mounting table 60 on which the detaching work table 50 is mounted horizontally. In this work table, the detachable work table 50 can be placed horizontally on the upper surface of the work table 60.

The suction cup 40 shown in FIGS. 2-5 is equipped with the suction cup main body 41 which has 41 A of suction surfaces closely_contact | adhered to the surface of the plastic film P in the front. Further, the suction cup 40 has a fixed plate 42 fixed to the back surface of the suction cup main body 41, and is connected to the detachment work table 50 via the fixed plate 42. As shown in FIG. 5, the fixed plate 42 is a plate that is bent so that the cross-sectional shape is L-shaped, and the plate main body 42 </ b> A is fixed to the back surface of the suction cup main body 41, and the bent portion 42 </ b> B is set to the back surface. It is protruding. The suction cup 40 shown in the figure connects the bent portion 42 </ b> B to the attachment / detachment work table 50. Further, the suction cup 40 has a grip 43 connected to the fixed plate 42. The grip 43 is formed by bending a rod having a thickness that can be grasped by a hand, and both ends thereof are fixed to the tips of the plate body 42A and the bent portion 42B, respectively. Thus, the suction cup 40 having the grip 43 on the back surface of the suction cup body 41 has a feature that the suction surface 41A of the suction cup body 41 can be accurately attached to and detached from the glass G by holding the grip 43 by hand. However, the suction cup does not necessarily have to connect the grip. The sucker without grip can be attached to and detached from the glass by holding the attachment / detachment work table. Further, the suction cup 40 is provided with an air pump 44 on the back surface of the suction cup body 41 for exhausting air on the suction surface 41 </ b> A side of the suction cup body 41. With the suction surface 41A of the suction cup body 41 in close contact with the plastic film P on the surface of the glass G, the air pump 44 exhausts the air on the suction surface 41A side to lower the pressure of the suction portion, Adsorbed on the surface of the plastic film P.

  The detachable work table 50 has a structure in which a pair of vertical frames composed of a first vertical frame 51 and a second vertical frame 52 are connected by a plurality of horizontal frames. In the detachable work table 50 shown in the figure, a first vertical frame 51 and a second vertical frame 52 are connected by four horizontal frames. The horizontal frame includes a pair of outer frames 53 that connect both ends of the first vertical frame 51 and the second vertical frame 52, and a pair of intermediate frames 54 that connect the middle of the first vertical frame 51 and the second vertical frame 52. Become. The detachable work table 50 in which the middle of the first vertical frame 51 and the second vertical frame 52 is connected by a pair of intermediate frames 54 can increase the strength of the entire detachable work table, and as shown in FIG. The frame 54 can be connected to the platform 60 and placed horizontally on the upper surface of the platform 60. Therefore, there is a feature that the large detaching work table 50 can be supported by the small mounting table 60. However, although the attachment / detachment work table is not shown, the first vertical frame and the second vertical frame can be mounted on the mounting table. The work table that connects the first vertical frame and the second vertical frame to the mounting table can support the detaching work table with a plurality of mounting tables.

  The total length of the vertical frame is preferably substantially equal to or larger than the width of the glass G to be adsorbed. This is because the outer frame 53 connected to both ends of the vertical frame can be attached to and detached from the mounting table 60 with the hand held from both sides of the glass G. The attachment / detachment work table 50 that can be held by hand from both sides of the glass G has the feature that it can be attached / detached to / from the mounting table 60 without touching the glass G and can be moved conveniently. However, the total length of the detachable work table 50 can be made shorter than the width of the glass G.

  The first vertical frame 51 connects the plurality of suction cups 40. The first vertical frame 51 shown in the drawing is connected to one suction cup 40 on the left and right sides of the intermediate frame 54. As shown in FIG. 4, these suction cups 40 are connected to the first vertical frame 51 in such a posture that the glass G covered with the plastic film P can be adsorbed with the detachment work table surface facing the glass G. Furthermore, the 1st vertical frame 51 has connected these suction cups 40 so that it can rotate along the surface of the glass G, as shown by the arrow of FIG. As shown in FIG. 5, the first vertical frame 51 fixes the connecting piece 55, and the suction cup 40 can be rotated by connecting the connecting piece 55 and the bent portion 42 </ b> B of the fixing plate 42 with a pin 56. They are connected. The suction cup 40 that can be rotated in the direction shown by the arrow in FIG. 4 rotates in a posture along the surface of the curved automotive glass G, and on the curved automotive glass G covered with the plastic film P. There is a feature that can be adsorbed closely.

  The second vertical frame 52 is located between the pair of intermediate frames 54 and connects one suction cup 40. The suction cup 40 is connected to the second vertical frame 52 so as to be removable. The suction cup 40 that is attached to and detached from the second vertical frame 52 includes a connection hook 45 that guides the second vertical frame 52 and connects it detachably. As shown in FIG. 5, the connecting hook 45 is a metal plate curved in a U shape, and the bent portion of the fixed plate 42 of the suction cup 40 faces the bottom of the curved portion with the opening at the tip facing outward. 42B is fixed. As shown in FIG. 4, the connecting hook 45 is fixed to the fixing plate 42 so that the second vertical frame 52 can be connected in parallel to the suction surface 41 </ b> A of the suction cup 40. The opening of the connecting hook 45 is sized to allow the second vertical frame 52 to be inserted. The suction cup 40 is connected to the second vertical frame 52 by inserting the second vertical frame 52 into the opening of the connection hook 45. In this way, the suction cup 40 connected to the second vertical frame 52 via the U-shaped connection hook 45 can rotate around the second vertical frame 52 as shown by the arrow in FIG. For this reason, there is a feature that when the curved glass G is sucked, it can be finely adjusted so that the relative orientation of the suction surface 41A of the suction cup 40 positioned up and down in FIG. .

  However, it is not always necessary to connect the second vertical frame with a structure that allows the suction cup to be attached and detached, and the suction cup can also be fixed. The suction cups connected so as not to be detachable from the second vertical frame are preferably connected so as to be rotatable in the direction indicated by the arrow in FIG. This detachable work table can suck and suck the suction cups connected to the second vertical frame so that the plurality of suction cups positioned vertically are brought into close contact with the surface of the curved automobile glass.

  Further, in the above detaching work table 50, two suction cups 40 are connected to the first vertical frame 51, and one suction cup 40 is connected to the second vertical frame 52. Thus, the structure in which the glass G is adsorbed by the three suction cups 40 has a feature that the glass G can be stably and reliably adsorbed while minimizing the number of the suction cups 40. However, the present invention does not specify the number of suction cups connected to the detaching work table as three. For example, the first vertical frame can connect three or more suction cups, and the second vertical frame can also connect two or more suction cups. Furthermore, the detachable work table can also connect the suction cups to the outer frame and the intermediate frame.

  As shown in FIGS. 2 and 6, the mounting table 60 includes a pair of foldable legs 61 and a mounting plate 62 connected to the upper ends of the pair of legs 61. This mounting table 60 is provided with a support portion 63 for horizontally supporting the detaching work table 50 on the mounting plate 62. The mounting plate 62 shown in FIG. 6 protrudes outward from both ends in the vertical direction and is provided with protruding pieces 64, and the upper surface of the protruding piece 64 and the end surface of the mounting plate 62 support the intermediate frame 54 of the attachment / detachment work table 50. The supporting part 63 is configured. As shown in FIG. 3, the vertical width of the mounting plate 62 is substantially equal to the inner space between the pair of intermediate frames 54, and the intermediate width in the state where the mounting plate 62 is fitted inside the pair of intermediate frames 54. The frame 54 is attached to and supported by the support portions 63 at both ends of the mounting plate 62. The protruding piece 64 has a sufficient length and a protruding amount that allows the intermediate frame 54 to be placed on the upper surface and stably supported. The protruding piece 64 shown in the figure has a total length substantially equal to the lateral width of the mounting plate 62. The protruding piece can be longer than the lateral width of the mounting plate to support the intermediate frame more stably. As described above, the support portion 63 constituted by the projecting pieces 64 provided at both ends of the mounting plate 62 has a feature that the mounting surface 60 can be used as a stepping table or the like because the upper surface of the mounting plate 62 can be made flat. However, the support part for supporting the detaching work table does not necessarily have to be a protruding piece, and can be a hook provided at both ends of the mounting plate, or a groove or positioning convex part provided on the upper surface of the mounting plate. You can also. Further, as shown by the arrow in FIG. 6, the mounting table 60 has a structure in which a pair of legs 61 can be folded, and thus has a feature that it can be folded compactly and carried conveniently.

The work table having the above structure is used as follows.
(A) As shown in FIG. 5, while holding the plastic film P, the suction cup is adsorbed to the glass and the desorption work table is connected.
(1) The suction cup 40 including the connection hook 45 is adsorbed on the upper center of the glass G through the plastic film P as shown in FIG. As shown in FIG. 5, the suction cup 40 adsorbs the plastic film P to the glass G while narrowing the plastic film P so that the opening of the connection hook 45 is in an upward posture.
(2) The second vertical frame 52 of the attachment / detachment work table 50 is connected to the connection hook 45 of the suction cup 40 adsorbed to the glass G through the plastic film P. At this time, as shown in FIG. 3, the detachment work table 50 is connected to the first vertical frame 51 as shown in FIG. 5 while the second vertical frame 52 is on the upper side and the first vertical frame 51 is on the lower side. The suction surface 41 </ b> A of the suction cup 40 is connected so as to face the surface of the glass G.
(3) The suction cup 40 connected to the first vertical frame 51 is adsorbed to the glass G through the plastic film P. In this state, the glass G is connected to the detaching work table 50 via the three suction cups 40 adsorbed at three points.

  As shown in FIG. 5, the working table of the embodiment has a suction cup adsorbed on the glass G via the plastic film P without removing the plastic film P, that is, between the adsorption surface and the glass surface. The suction cup can be adsorbed with a plastic film interposed. In common sense, if the heavy glass G is adsorbed through the plastic film P in this way, the suction cup is likely to come off from the glass G, and the glass G may fall, which is dangerous. However, in the working table of the embodiment, even if the glass G is adsorbed through the plastic film P, the glass G can be effectively prevented from falling off the suction cup. This is because the plastic film P and the glass G are in close contact. In order to increase the adhesion between the plastic film P and the glass G, the characteristics of the plastic film P described above and the coating method thereof are involved. Furthermore, in order to prevent the peeling of the plastic film P, the peeling tape M is important as will be described in detail later.

  In addition, in order to prevent the plastic film P densely coated on the glass G from being peeled off in the subsequent process, the glass is not moved by directly holding the suction cup adsorbed on the glass G, but is removed. The suction cup connected to the table is adsorbed to the glass, and the glass is moved with this desorption work table. If an attempt is made to move the glass by directly holding a plurality of suction cups adsorbed on the glass, the direction and magnitude of the force acting on each suction cup will not be a fixed direction, and the suction cups will easily come off the glass. On the other hand, when the glass is moved while holding the desorption work table that adsorbs the glass with the suction cup, the direction of the force acting on the plurality of suction cups connected to the desorption work table can be made constant and the force acting Can be distributed in a balanced manner to each suction cup, so that the suction cup can be effectively prevented from coming off the glass. As described above, the method of adsorbing glass in a state where it is covered with a plastic film can effectively prevent the glass from being stained or damaged, and can work very efficiently, and can realize high-quality work.

As described above, the desorption work table 50 is connected to the glass G through the plastic film P. The detaching work table 50 is connected to the glass to be broken and removed, or is connected to the newly attached glass. When removing the broken glass, the broken glass is removed from the window frame by using a desorption work table connected to the glass or by using a desorption device described later. When a new glass is mounted, various operations are performed in a state where a desorption work table connected to the glass is placed on the table and supported horizontally.
(B) A desorption work table connected to glass is placed on the table and supported horizontally.
(1) The detachment work table 50 connected to the glass G through the suction cup 40 is moved to above the mounting table 60. At this time, the glass G can be carried with the desorption work table 50 without touching the glass.
(2) The demounting work table 50 in which the intermediate frame 54 of the demounting work table 50 is connected to the support portion 63 provided on the mounting plate 62 of the mounting table 60 and the glass G is adsorbed by the suction cup 40 is shown in FIG. As shown, it is placed horizontally on the platform 60. In this state, the glass G is supported in a horizontal posture on the mounting table 60, and the working efficiency of the glass G kept horizontal is significantly improved.

(Plastic film cutting process)
By the way, when installing a new window glass in an automobile, the window glass is watertightly fixed to the window frame of the automobile with an adhesive. In order to achieve this, an adhesive is applied to the peripheral edge of the window glass in advance, and this window glass is set at a fixed position on the vehicle body. The processing method of the glass G for achieving this will be described. First, in the glass G supported horizontally by the desorption work table 50, the coated plastic film P is cut along the outer peripheral edge of the glass G and removed. Thereby, the outer peripheral part of the glass G is exposed outside.

  The plastic film P is cut in the glass G by a front surface F (upper side surface in FIG. 2) located on the vehicle inner side when installed on the vehicle body and a rear surface R (lower side surface in FIG. 2) opposite to the front surface. It is enforced for both sides.

  Further, as another method for exposing the outer peripheral portion of the glass G, a plastic film P having a size reduced by a gusset width exposed in advance may be adhered to the glass G. Thereby, the work of cutting the plastic film P can be omitted.

(Peeling tape attachment process)
Further, as shown in FIG. 2, a peeling tape M is stuck along the cut edge of the plastic film P, and the plastic film P and the glass G are brought into close contact with the peeling tape M. The peeling tape M has an adhesive force that can be easily peeled if pulled by hand . Also, it does not occur traces of peeling because the adhesive does not remain. As the peeling tape M, for example, a masking tape can be used.
A method for applying the release tape M will be specifically described with reference to FIG. The side view of FIG. 5 shows a state in which the suction cup 40 is adsorbed to the glass G covered with the plastic film P. However, this side view exaggerates the thickness of the plastic film P, the peeling tape M, and the like for convenience. As shown in the figure, the peeling tape M is stuck so as to straddle both surfaces of the plastic film P and the glass G with the cut edge of the plastic film P as a boundary. Furthermore, the peeling tape M is stuck and adhered to the plastic film P and the glass G so that air is not mixed inside thereof.

  The peeling tape M prevents displacement and peeling of the plastic film P that is not bonded to the glass G with an adhesive or the like. In addition, foreign matter such as dust and soot or air is prevented from entering between the plastic film P and the glass G. Therefore, the plastic film P whose surface is adsorbed by the suction cup on the rear surface R of the glass G does not allow foreign matter that worsens the suction of the suction cup to enter inside thereof, so that the suction cup is firmly attached to the plastic film P while adsorbing the plastic film P. Can be adsorbed on the glass G. Furthermore, the plastic film P having the outer peripheral edge attached to the window glass G with the release tape M can adhere the release tape M to the window glass G without wrinkling. That is, the disadvantage that the suction cup cannot be firmly adsorbed because wrinkles are generated in the plastic film P, the suction cup is firmly adsorbed to the window glass G, and the heavy window glass G can be safely attached to the automobile.

  Further, after firmly attaching the plastic film P and the glass G with the peeling tape M, an adhesive is applied to the peripheral portion of the front surface of the glass G that is not covered with the plastic film P. In addition to the above features, the peeling tape M on the front surface of the glass G can accurately position the place where the adhesive is applied, and can prevent excess adhesive from entering the plastic film P.

  The glass G processed as described above is attached to the window frame of the vehicle body by holding the desorption work table by hand. After the glass G is mounted, the peeling tape M is peeled off, and the plastic film P is further removed from the glass G. Alternatively, when the glass G is attached to the vehicle body, the glass G is attached to the window frame of the vehicle body using a desorption device described later.

  The lorry 1 has a loading platform 2 that is moved up and down by a vertical drive mechanism 8. The vertical drive mechanism 8 moves the cargo bed 2 up and down while holding the loading platform 2 in a horizontal posture. Further, the loading platform 2 is stopped at a predetermined height. The illustrated vertical drive mechanism 8 includes a pair of X frames 10 connected between a chassis 9 and a loading platform 2 of the lorry 1 and an upper and lower cylinders 11. The X frame 10 is connected to the chassis 9 and the loading platform 2 so that the right end of the X frame 10 can be rotated in the vertical plane, and a roller 12 is provided at the left end. The roller 12 moves in the horizontal direction along a rail 13 provided on the chassis 9 and the loading platform 2. The upper and lower cylinders 11 have lower ends connected to the chassis 9, and the upper ends of the rods 11A are connected to the lower surface of the loading platform 2 so as to be able to rotate in a vertical plane. The vertical drive mechanism 8 extends the rod 11A of the upper and lower cylinders 11 to lift the loading platform 2, and contracts the rod 11A to lower the loading platform 2. The height of the loading platform 2 is adjusted by controlling the position where the rod 11A of the upper and lower cylinders 11 is expanded and contracted. The upper and lower cylinders 11 are hydraulic cylinders or electric cylinders. The hydraulic cylinder is connected to a hydraulic pump via a control valve, and the control valve is opened, the rod 11A is extended by the hydraulic pump, and the loading platform 2 is raised. The hydraulic cylinder is connected to a return circuit via a control valve, and the control valve is opened to contract the rod 11A to lower the loading platform 2. The electric cylinder extends and contracts the rod with a servo motor.

  The front and rear platform 3 is mounted on the cargo platform 2 that moves up and down of the lorry 1 so that it can move back and forth. The front and rear platforms 3 are attached to the loading platform 2 so as to be removable or connected so as not to be removable. The front and rear platform 3 in the figure includes a main body frame 3A and a protruding arm 3B protruding from the rear end of the main body frame 3A. The main body frame 3 </ b> A has wheels 14 that travel along rails 15 connected to the loading platform 2 on both sides. The wheel 14 travels on the rail 15, and the main body frame 3 </ b> A is moved forward and backward of the loading platform 2. The rail 15 is provided inside a square-shaped rotary frame 16 connected to the loading platform 2. That is, the front and rear platform 3 is connected to the loading platform 2 via a rotating frame 16 having rails 15 on the inside.

  The rotating frame 16 has a structure in which a pair of vertical frames 16A having rails 15 on the inside are connected by a plurality of horizontal frames 16B. The rotation frame 16 is connected to the loading platform 2 via a horizontal rotation mechanism 33 so that the rotation frame 16 can be rotated in a horizontal plane. The rotating frame 16 shown in FIG. 8 connects the center of the horizontal frame 16B that connects the front ends of the pair of vertical frames 16A to the loading platform 2 via the rotating shaft 34, and the rear end of each vertical frame 16A. It is connected to the loading platform 2 via a movable carriage 35 and a traveling rail 36. The movable carriage 35 is connected to the traveling rail 35 via a bearing so that the rotating frame 16 can move smoothly along the traveling rail 35. The movable carriage 35 is rotatably connected to the lower surface of the vertical frame 16A so that the rotating frame 16 can be rotated without difficulty. Furthermore, the movable table 35 car is connected to the vertical frame 16A in a somewhat playful state, so that the rotating frame 16 can be rotated more smoothly. The traveling rail 36 is a rail for traveling the movable carriage 35 and is fixed to the loading platform 2 by bolting or welding. The horizontal rotation mechanism 33 rotates the rotation frame 16 about the rotation shaft 34 in the direction indicated by the arrow A in FIG.

  The rotating frame 16 can be rotated by hand, for example. Although the rotation frame 16 moved by hand is not shown, it can be stopped at a predetermined position by a positioning mechanism. The positioning mechanism is a mechanism that stops the rotating frame 16 at a specific position. The rotating mechanism stops the rotating frame 16 at an optimal position and temporarily fixes it so as not to move. However, the rotating frame can be rotated electrically. As described above, the rotating frame 16 that rotates in the horizontal plane has the advantage that the direction of the front and rear base 3 can be finely adjusted, and the front and rear base 3 can be moved to a more accurate position. Further, the horizontal rotation mechanism 33 including the rotation shaft 34, the movable carriage 35, and the travel rail 36 can rotate the rotation frame 16 with the simplest mechanism. However, the horizontal turning mechanism can be any other mechanism that can turn the turning frame with respect to the loading platform.

  Further, the detaching mechanism 80 shown in the drawing connects the front and rear cylinders 17 between the rotating frame 16 and the main body frame 3A in order to move the main body frame 3A back and forth. In the front and rear cylinders 17, the rod 17 </ b> A has a front end connected to the main body frame 3 </ b> A and a rear end connected to the rotating frame 16. The front and rear cylinders 17 are hydraulic cylinders or electric cylinders, and the expansion and contraction positions are controlled by a control circuit. This detaching apparatus can be used conveniently because the main body frame 3A can be moved back and forth by expanding and contracting the front and rear cylinders 17. However, the detachable device can also manually move the main body frame back and forth.

  The front / rear stand 3 in the figure is a main body frame 3A in which a pair of vertical cylinders 18 arranged in the front / rear direction of the loading platform 2 are connected by a horizontal frame 19. The vertical cylinder 18 is a metal square pipe extending in the front-rear direction of the loading platform 2, and a horizontal frame 19 is welded and fixed to the rear end, the front end, and the center portion. The main body frame 3 </ b> A has wheels 14 fixed to both sides of the vertical cylinder 18. Further, the telescopic rod 20 is connected to the vertical cylinder 18 so that the telescopic rod 20 can be expanded and contracted, and a work table detaching work table 50 can be connected to the rear end of the telescopic rod 20.

  The telescopic rods 20 are metal square pipes inserted so as to be able to be taken in and out of the vertical cylinders 18 and are respectively inserted into the pair of vertical cylinders 18. The pair of telescopic rods 20 is inserted at the front end side into the vertical cylinder 18 and connected at the rear end by a connecting rod 27. Further, the telescopic rod 20 is connected to the rear end with a hook 37 that connects and supports the detachable work table 50. The telescopic rod 20 shown in FIG. 9 is connected so that the hook 37 can be detached. Furthermore, the hook 37 shown in the drawing is connected to the telescopic rod 20 via a coil spring, which is an elastic body 38, so that it can elastically expand and contract. As shown in FIG. 7, the telescopic rod 20 is connected to the lower portion of the detachment work table 50 by inserting the first vertical frame 51 into the hook 37 with the hook 37 connected to the rear end. Furthermore, the upper part of the attachment / detachment work table 50 connected to the telescopic rod 20 is connected to the tilt arm 5 via a wire 39. That is, the attachment / detachment work table 50 has the first vertical frame 51 supported by the hook 37 at the rear end of the telescopic rod 20 and the second vertical frame 52 supported by the wire 39 connected to the tilting arm 5. The automobile glass G is held in the inclined posture shown in the figure.

  Further, the detachable mechanism 80 is configured such that the detachable work table 50 is inclined in the direction indicated by the arrow C in FIG. 7 with the lower part of the detachable work table 50 connected to the hook 37 at the rear end of the extendable rod 20. 20 can also be used as a workbench. In this state, the automobile glass G is supported in a posture close to the horizontal, so that it is possible to perform operations such as applying an adhesive to the peripheral edge. The hook 37 connected to the rear end of the telescopic rod 20 can be shaped so that the attachment / detachment work table 50 does not come off even if the connected work table 50 is tilted in the direction indicated by the arrow C in the figure.

  The protruding arm 3B is fixed by welding to the rear end of the main body frame 3A so as to protrude rearward from the main body frame 3A. The protruding arm 3 </ b> B is fixed to the main body frame 3 </ b> A so as to incline in an upward gradient toward the rear. The protruding arm 3 </ b> B is provided on the front and rear stand 3 in order to shorten the tilting arm 5. Therefore, the front and rear stand 3 having the protruding arm 3B can be made to have a strong structure by shortening the tilting arm 5. However, the detaching apparatus of the present invention can also connect the tilting arm directly to the main body frame without providing the projecting arms on the front and rear stands.

  The tilt arm 5 is attached to the rear end portion of the projecting arm 3B, which is the front and rear stand 3, so that it can tilt and move laterally. The illustrated attachment / detachment mechanism 80 connects the two tilting arms 5 to the protruding arm 3B. The tilt arm 5 is connected to the projecting arm 3 </ b> B via the rotation shaft 21. The tilt arm 5 is connected to both ends of the rotating shaft 21 at right angles to the rotating shaft 21. The rotating shaft 21 is inserted into a through hole provided in the rear end portion of the projecting arm 3B which is the front and rear stand 3 so as to be able to rotate and move in the axial direction. When the rotating shaft 21 is rotated, the tilting arm 5 fixed to the rotating shaft 21 is tilted. When the rotating shaft 21 is moved in the axial direction, the tilting arm 5 is moved in the lateral direction.

  The tip of the tilting arm 5 is connected to the detaching work table 50. The tilting arm 5 shown in the figure is connected to the upper part of the detaching work table 50 via a wire 39. However, although not shown, the tip of the tilting arm can be connected to the detaching work table via a rod. The wire 39 is, for example, a wire having sufficient strength such as a wire, and is connected to the tilting arm 5 and the attachment / detachment work table 50 through a connector such as a hook so that the wire 39 can be attached / detached. The tilting arm 5 is connected so that a wire rod 39 can be attached and detached by providing a connecting tool 24 such as a connecting ring or hook at the tip. Further, the detaching work table 50 connects the wire 39 to the suction cup 40 connected to the upper side, and connects the wire 39 via the suction cup 40. As shown in FIG. 5, the suction cup 40 connected to the upper side of the detaching work table 50 is provided with a connecting ring 46 fixed to a fixing plate 42, and a wire rod 39 is connected to the connecting ring 46. However, the wire can be directly connected to the desorption work table.

  The tilting mechanism 6 tilts the tilting arm 5 to adjust the angle with respect to the horizontal plane of the detachable workbench 50 connected to the tip of the telescopic rod 20, that is, the tilt angle. The windshield of an automobile is fixed with an inclination almost without exception. For this reason, the desorption mechanism 80 needs to incline the automobile glass G to be adsorbed in accordance with the window frame of the automobile. The illustrated tilting mechanism 6 includes a drive arm 28 that is fixed to the rotary shaft 21 so as not to rotate, and a tilt cylinder 29 that is connected to the drive arm 28. The tilting cylinder 29 is connected so that the tip of the rod 29 </ b> A is connected to the drive arm 28, and the rear end is connected to the main body frame 3 </ b> A of the front / rear base 3 so that it can be rotated in a vertical plane. The tilt cylinder 29 is a hydraulic cylinder or an electric cylinder. These cylinders control the rotation angle of the rotating shaft 21 by controlling the length of expansion and contraction by the control circuit, as in the case of the front and rear cylinders 17 described above. That is, the tilting cylinder 29 drives the drive arm 28 to rotate the rotating shaft 21, and the rotating rotating shaft 21 tilts the tilting arm 5 to a predetermined angle.

  The tilt mechanism 6 tilts the tilt arm 5 to adjust the tilt angle of the detachable work table 50. When the tilting arm 5 is tilted in the direction indicated by the arrow A in FIG. 7, the attachment / detachment work table 50 is tilted in the direction indicated by the arrow B in the figure, so that the automobile glass is inclined. Conversely, when the tilting arm 5 is tilted in the direction opposite to the arrow A in FIG. 7, the attachment / detachment work table 50 is tilted in the direction opposite to the arrow B in the figure, so that the vehicle glass approaches a vertical posture. Zuku. However, the inclination angle of the attachment / detachment work table 50 is determined not only by the inclination angle of the inclination arm 5 but also by the length of the wire 39 and the length of pulling out the telescopic rod 20. For example, if the pull-out amount of the telescopic rod 20 is reduced or the wire rod 39 is lengthened, the inclination angle of the detachment work base 50 with respect to the horizontal plane is reduced, and conversely, the pull-out amount of the telescopic rod 20 is increased or the wire rod 39 is shortened. Then, the inclination angle of the detachment work table 50 is increased. Therefore, the detaching mechanism 80 determines the amount of pull-out of the telescopic rod 20 and the length of the wire rod 39 so that the inclination angle of the detaching work table 50 is optimized according to the type of the vehicle from which the vehicle glass is detached, and the tilt mechanism 6, the tilting arm 5 can be tilted to finely adjust the tilt angle of the detachable work table 50.

  Furthermore, the tilting arm 5 shown in the drawing is provided with a holder 25 at the tip. As described above, the tilting arm 5 having the holder 25 at the tip is not shown, but a suction cup can be connected to the holder 25 and the glass can be adsorbed and removed by the suction cup. Thus, the tilting arm 5 that can connect the suction cup to the tip is connected to both ends of the rotating shaft 21 so that it can elastically expand and contract. The tilt arm 5 shown in the figure is connected to the rotary shaft 21 via a linear motion bearing 22 and an elastic body 23 that can move in the axial direction. The linear motion bearings 22 are fixed to both ends of the rotating shaft 21 and move the tilting arm 5 in the axial direction. The elastic body 23 is a coil spring, and the tilting arm 5 is inserted into the coil spring. The elastic body 23 that is a coil spring elastically expands and contracts the tilting arm 5. However, the tilting arm that does not connect the suction cup to the tip does not necessarily need to be connected to both ends of the rotating shaft so that it can elastically expand and contract.

  The lateral drive mechanism 7 moves the rotary shaft 21 in the axial direction. The tilting arm 5 that moves in the horizontal direction moves the detachable work table 50 in the horizontal direction while pulling the detachable work table 50 with the wire 39 connected to the tip. Since the axial direction of the rotating shaft 21 is horizontal and horizontal, the lateral drive mechanism 7 moves the detachment work platform 50 laterally with respect to the loading platform 2. This is because the automobile glass G connected to the detachable work table 50 is perfectly matched with the window frame of the automobile to be mounted. By adjusting the stop position of the lorry 1, it is possible to adjust the lateral position between the automobile glass G and the automobile on which the automobile glass G is mounted. However, it is extremely difficult to actually match the position of the truck 1 exactly. The attachment / detachment work table 50 to which the automobile glass G is connected is brought close to the window frame of the automobile, and the lateral drive mechanism 7 moves the attachment / detachment work table 50 in the lateral direction so that the automobile glass G is accurately aligned with the attachment position.

  The illustrated lateral drive mechanism 7 includes a screw rod 30 disposed parallel to the rotary shaft 21, a nut member 31 screwed into the screw rod 30 and connected to the rotary shaft 21, and the screw rod 30. And a rotating motor 32. The nut material 31 is connected to the rotating shaft 21 so as not to move. The motor 32 is a servo motor, and rotates the screw rod 30 to move the nut material 31 along the screw rod 30 in the axial direction. Since the nut material 31 is connected to the rotation shaft 21, the rotation shaft 21 moves in the axial direction, that is, the lateral direction together with the nut material 31. The motor 32 is controlled by a control circuit (not shown) and rotated in the forward and reverse directions. The position of the nut member 31 can be controlled by controlling the rotational position of the motor 32.

  The above-described detaching apparatus can be conveniently used for detaching a bonnet type automobile glass G, in other words, a passenger car type windshield such as a 3-box car or a 2-box car. In particular, since the bonnet type automobile is located at a position where the windshield retracts from the bonnet, when the automobile glass G is detached from this type of automobile, the telescopic rod 20 is extended to remove the automobile glass G.

The above demounting apparatus attaches the automobile glass to the automobile as follows.

The lower part of the detachable work table 50 is hooked on the hook 37 at the rear end of the telescopic rod 20 to connect the detachable work table 50 to the rear end of the telescopic rod 20. The detachment work table 50 is connected, for example, by inserting the first vertical frame 51 into the hook 37.
(4) The upper part of the attachment / detachment work table 50 is connected to the tip of the tilt arm 5. The upper part of the attachment / detachment work table 50 and the tip of the tilting arm 5 are connected, for example, by stretching a wire 39.
(5) The rotation frame 16 is rotated by the horizontal rotation mechanism 33 to adjust the direction of the front and rear stand 3.
(6) The rod 29A of the tilt cylinder 29 is taken in and out by the tilt mechanism 6, and the tilt angle of the detachment work table 50 is adjusted. In this step, the inclination angle of the automobile glass G is adjusted to the window frame of the automobile.
(7) The detachment work table 50 is moved in the horizontal direction to accurately adjust the horizontal position of the automobile glass G. At this time, the lateral drive mechanism 7 is driven, and the detachment work table 50 connecting the automobile glass G can be easily moved to adjust the lateral position.
(8) The loading platform 2 is moved up and down to adjust the vertical position of the automobile glass G.

However, the steps (5) to (8) are not necessarily performed in this order, and these steps are performed in random order to adjust the posture and position of the automobile glass.
(9) After the automobile glass G is disposed at the approach position in front of the window frame, the front and rear stand 3 is retracted, and the automobile glass G is mounted at an accurate position of the window frame.
(10) After the automobile glass G is fixed to the window frame, the suction of the suction cup 40 is released, and the front / rear stand 3 is moved forward to separate the detachable work table 50 from the automobile glass G.
(11) The peeling tape M is peeled off, and the plastic film P is further removed from the glass G.

When removing the broken car glass, do as follows.
(1) In the process described in the above (A), the detachment work table 50 is connected to the automobile glass G via the suction cup 40.
(2) Move the lorry 1 to the front of the car and pull out the telescopic rod 20 from the vertical cylinder 18. A hook 37 is attached to the rear end of the telescopic rod 20. Thereafter, the loading platform 2 is moved up and down, and the vertical position is adjusted by the horizontal rotation mechanism 33, and the hook 37 at the rear end of the telescopic rod 20 is positioned below the detachment work platform 50.
(3) The lower part of the attachment / detachment work table 50 is hooked on the hook 37 at the rear end of the telescopic rod 20 to connect the attachment / detachment work table 50 to the rear end of the telescopic rod 20 and the upper part of the attachment / detachment work table 50 is connected to the tilt arm 5. Connect to the tip. The upper part of the attachment / detachment work table 50 and the tip of the tilting arm 5 are connected, for example, by stretching a wire 39.
(4) After the automobile glass G is removed from the window frame of the automobile, the front and rear stand 3 is advanced to pull the automobile glass G away from the window frame.

  Furthermore, as shown in FIG. 9, the detaching apparatus of the present invention can be connected to the rear end of the telescopic rod so that the horizontal base 70 can be detached. The horizontal base 70 has a flat plate 72 fixed to the upper surface of a frame member 71 that is framed in a square shape. The horizontal width of the horizontal base 70 is sufficiently wider than the interval between the telescopic rods 20 and is wide enough for an operator to stand on the work. The telescopic rod 20 is provided with a connecting portion 26 at the rear end in order to detachably connect the horizontal base 70. The connecting portion 26 shown in the figure is a square pipe disposed in parallel above the telescopic rod 20, and the rear end of the square pipe is welded to the rear end of the telescopic rod 20 and fixed. The square pipe as the connecting portion 26 is parallel to the telescopic rod 20 and is fixed to the telescopic rod 20 in a separated state. Further, in order to insert the connecting portion 26, the horizontal base 70 is provided with a connecting hole 73 at a position where a pair of frame members 71 extended in the lateral direction are opposed to each other.

  The horizontal base 70 having this structure is connected to the telescopic rod 20 by inserting the connecting portion 26 fixed to the upper side of the telescopic rod 20 into the connecting hole 73 of the frame member 71 with the telescopic rod 20 pulled out. Therefore, the connecting portion 26 has a sufficient length that can be inserted into the pair of connecting holes 73 opened facing each other. The horizontal base 70 connected with this structure can be reliably connected to the telescopic rod 20. Further, the horizontal base 70 is removed from the telescopic rod 20 after use, and the telescopic rod 20 is inserted into the vertical cylinder 18 and stored. The vertical cylinder 18 shown in FIG. 9 is composed of upper and lower two-stage square pipes, with the lower pipe serving as the insertion portion for the telescopic rod 20 and the upper square pipe serving as the insertion portion for the connecting portion 26. The vertical cylinder 18 having this structure can accommodate the telescopic rod 20 including the connecting portion 26 in a compact manner.

  Thus, the horizontal base 70 connected to the telescopic rod 20 has the feature that it can be used very conveniently as a scaffold when working at high places. This is because the cargo can be moved by the truck 1, and the vertical position of the horizontal platform 70 can be adjusted very easily by operating the platform 2 up and down. In particular, since buses and trucks have a high driver's seat, the position of the windshield is also high, and it is difficult to work at this high position. In this way, the detaching apparatus that can be moved up and down with the horizontal base 70 attached can be used very conveniently as a scaffold that can be easily realized without the need to assemble a scaffold as in the prior art.
