Description

  The present invention relates to a coating auxiliary device.

  Some base materials constituting interior materials for automobiles (for example, door trims) have a complicated curved surface shape. Since it is difficult to automate the work of attaching the skin material to the surface of such a base material, it is the actual situation that it is still performed manually by workers today.

  For example, as an operation method for attaching the skin material to the surface of the base material, there is a method of using a release paper whose surface is subjected to peeling processing, for example. In this method, a plurality of small pieces of release paper are preliminarily spread on the surface of the base material to which the adhesive is applied, and the skin material is overlaid on the release paper, and then the release paper is placed. In this method, the skin material is gradually attached to the surface of the base material by gradually pulling it out.

  Such an operation for applying the skin material is very complicated, and conventionally, an apparatus for assisting the operation for applying the skin material has been proposed. For example, Patent Document 1 discloses an apparatus that assists in the work of attaching a skin material having a sewing line to the surface of a base material. This device has a substrate mounting table on which a substrate having a surface coated with an adhesive is placed, and a swing arranged above the substrate so as to cover the substrate with the skin material placed thereon. And a blade for pressing and positioning the end portion (sewing line) of the skin material protruding from the end portion of the cover body against the base material. In this apparatus, after the end portion of the skin material is positioned, the cover body is retracted, so that the skin material is gradually put on the substrate and attached.

  For example, when a skin material is affixed to a base material having a complicated curved surface shape, there is a case where it is desired to appropriately change the angle of the mounting table (workbench) so that an operator can easily affix it. There is also a circumstance that the angle of the mounting table (work table) at which the operator can easily attach the skin material to the base material varies depending on the difference in physique and the level of proficiency of the work.

  However, the conventional auxiliary device has a problem that workability of attaching the skin material to the base material is poor because the position of the mounting table (work table) on which the base material is placed is fixed.

  An object of the present invention is to provide a coating auxiliary device that improves the efficiency of the operation of attaching a sheet-shaped coating material to the surface of a substrate having a curved surface.

  The coating auxiliary device according to the present invention is a coating auxiliary device that assists the operation of attaching a sheet-like coating material to the surface of a substrate having a curved surface, and is disposed in front of an operator, and the substrate is placed on the coating auxiliary device.

And fixing means for stopping rotation of the work table and fixing an angle at which the work table supports the base material.

  The covering auxiliary device can rotate and fix the work table to a desired angle and can adjust the angle at which the covering material is attached to the surface of the substrate having a curved surface. Good workability for pasting.

  In the coating auxiliary device, the other end is attached to the surface of the base material in order from the one end arranged on the operator side to the other end arranged on the opposite side. A thing provided with the suspension means which suspends the above-mentioned covering material so that the above-mentioned other end may be pulled up away from the surface of a material is preferred. By providing such a suspension means, the covering auxiliary device easily attaches the covering material to the surface of the base material in order from the one end to the other end while aligning the covering material on the surface of the base material. Workability is further improved.

  In the covering assisting device, the suspension means is connected to the holding portion that holds the other end of the covering material, and an urging means that urges the holding portion in a direction in which the covering material is pulled. It is preferable to have. If the suspension means of the covering auxiliary device has such a configuration, it is possible to continue to apply tension to the covering material following the rotation operation of the work table, and the covering material is applied to the base material. Workability is further improved.

  The covering auxiliary device may include a rotation preventing means for preventing the work table from rotating so that the work table does not rotate beyond a predetermined angle range. When the covering auxiliary device includes the rotation preventing means, the work table is prevented from rotating beyond a predetermined angle range, and the workability of attaching the covering material to the base material is further improved.

Specifically, when viewed from the worker X, there are a total of five suspension means 9, three on the back side of the work table 6, one on the left side of the work table 6, and one on the right side of the work table 6. The covering auxiliary device 5 is provided. In addition, three suspension means 9 are installed in the back side of the work table 6 so as to be arranged in a line in the left-right direction.

  The suspension means 9 disposed on the back side of the work table 6 is erected on a support frame portion 93 extending from the work table support portion 72 toward the back side. The support frame portion 93 has a frame shape and is provided so as not to interfere with the rotating work table 6. The suspension means 9 provided on the left and right sides of the work table 6 are attached to the left and right frame parts 72 a constituting the work table support part 72.

  The holding portion 91 is formed of a clip using an elastic force that can be held with the end portion (the other end 3 b) of the skin material 3 interposed therebetween. The holding portion 91 is not particularly limited as long as it can hold the end portion 3b of the skin material 3, and, for example, a hook-shaped member may be used.

  FIG. 5 is an explanatory view schematically showing the suspending means 9. The suspending means 9 shown in FIG. 5 is installed on the back side of the work table 6, but the basic structure is the same as that installed on the left and right of the work table 6.

  As shown in FIG. 5, the urging means 92 of the suspending means 9 includes a weight 92a, a first wire 92b, a pulley 92c, a cushioning material 92d, a connection ring 92e, and a second wire 92f. ing.

  The weight 92a is connected to one end 92b1 of the first wire 92b. In addition, the weight of the weight 92a is set so that tension | tensile_strength always acts with respect to the skin material 3 hold | maintained by the holding | maintenance part 91 so that it may mention later. The urging means 92 includes two pulleys 92c. The two pulleys 92c are arranged in a line at intervals from each other, and a first wire 92b is hung on each pulley 92c so as to bridge between them. Each pulley 92c is attached to a pulley support member 94 erected on the support frame portion 93 described above. Each pulley 92c of the suspension means 9 provided on the left and right of the work table 6 is also attached to a pulley support member 95 having the same structure (see FIG. 2 and the like).

  The other end 92b2 of the first wire 92b is connected to the connection ring 92e. It should be noted that the end portion (the other end 92b2) of the first wire 92b is the center of the cushioning material 92d so that the disk-like cushioning material 92d is disposed between the connection ring 92e and the pulley 92c. Is inserted through the through hole. The connection ring 92e and the holding portion (clip) 91 are connected to each other by the second wire 92f.

  The biasing means 92 is configured such that when the first wire 92b is pulled by the weight 92a, the holding portion 91 connected thereto pulls up the skin material 3. For example, in a state where the holding portion 91 holds nothing, the first wire 92b is pulled downward by the fall of the weight 92a. The fall of the weight 92a stops when the connection ring 92e contacts the pulley 92c with the cushioning material 92d interposed therebetween. Further, when the end portion (other end) 3 b of the skin material 3 is held by the holding portion 91, the weight 92 a moves in the vertical direction so as to balance the weight of the skin material 3.

  When the holding portion 91 holding the end portion (the other end) 3 b of the skin material 3 is pulled by the urging means 92, a tension always acts on the skin material 3. That is, even when the skin material 3 is pulled away from the pulley 92c side against the weight 92a, or when the skin material 3 is moved closer to the pulley 92c side so that the weight 92a falls, The tension will always be applied. By suspending the skin material 3 with such a suspending means 9, the worker X can spread and hold the skin material 3 while suppressing the occurrence of wrinkles, twists and the like. In addition, the end 3 a side of the skin material 3 is usually held by the hand of the worker X or placed on the surface 2 a of the base material 2.

  As shown in FIG. 3, the skin material 3 is held at the end (other end) 3 b by the five suspension means 9. In this way, the skin material 3 is reliably spread using the plurality of hanging means 9. The number of the suspension means 9 to be installed and the installation angle (direction in which the tension is applied) are appropriately set according to the size and shape of the skin material 3. In the case of the present embodiment, the suspending means 9 installed on the left and right of the work table 6 are set at angles (directions in which tension is applied) so as to face the support portions 61. Then, the three suspension means 9 arranged on the back side of the work table 6 are arranged so that the angle (tension acts) substantially along the short direction of the work table 6 (main body portion 62) while facing the support portion 61. Direction) is set.

  Next, with reference to FIG. 6 to FIG. 9 and the like, the worker X uses the covering assisting device 5 of the present embodiment to attach the skin material 3 to the surface 2a of the base material 2, and the covering assisting device. The operation of No. 5 will be described.

  FIG. 6 is an explanatory view showing a state in which the base material 2 is placed on the work table 6 of the auxiliary coating apparatus 5 and the skin material 3 is suspended by the suspension means 9. As a first step, as shown in FIG. 6, first, the operator X places the base material 2 on the work table 6 of the coating auxiliary device 5. In this state, the angle at which the work table 6 of the covering auxiliary device 5 supports the base material 2 is horizontal. In the present embodiment, the angle at which the work table 6 supports the base material 2 will be described with reference to the surface of the plate material 62 c included in the main body 62 of the work table 6. In this state, the fixing means 8 of the covering auxiliary device 5 causes the stop portion 82 to be lifted by the air cylinder 81 to press the gear 64 provided on the rotating shaft 63, and the teeth (teeth) included in the stop portion 82 are provided. The rotation shaft 63 is prevented from rotating by meshing the teeth (dentation) included in the gear and the gear 64 with each other.

  Specifically, in the first step, the base material 2 is placed on the placement portion 61a of the support portion 61 included in the work table 6 in a form that covers the back surface 2b. An adhesive is applied in advance to the surface 2a of the substrate. In addition, the back surface 2b of the base material 2 is provided with the grid-like rib portions 2e as described above, and each rib portion 2e is fitted into a concave groove portion 61c formed on the surface of the placement portion 61a. This prevents the base material 2 from being displaced on the placement portion 61a. In addition, a plurality of plate pieces 2 c are provided on the periphery of the substrate 2. The plate piece portion 2c is a portion that is caulked (for example, ultrasonic melting caulking) with a boss portion of the other base material when the base material 2 is attached to the other base material. By inserting the locking pin 61d provided in the support portion 61 into the hole portion 2d provided in the plate piece portion 2c from the lower side, the base material 2 is surely placed on the placement portion 61a of the support portion 61. Positioned. Therefore, even if the work table 6 rotates and the work table 6 is inclined, the base material 2 is prevented from being detached from the support portion 61 of the work table 6.

  As shown in FIG. 6, the surface 2a of the substrate 2 has a curved surface shape. In addition, in the surface 2a of the base material 2 at the end portion or the like disposed on the worker X side, a concave groove 2a1 elongated in a linear shape so as to correspond to the position of the stitch line 4 of the skin material 3 is provided. Is formed.

  Next, as a second step, the skin material 3 is attached to the suspending means 9 as shown in FIG. Specifically, the operator X is arranged so that the design surface 3c is arranged on the upper side and the back surface 3d is arranged on the lower side while aligning the position of the skin material 3 and the position of the base material 2 so as to overlap each other. While holding the end (one end) 3 a side by hand, the end (other end) 3 b is held by the holding portion 91. At that time, the skin material 3 is in a state where the end portion 3b side is pulled up and expanded by the urging means 92.

  FIG. 7 is an explanatory view showing a state in which the end portion 3 a of the skin material 3 on which the stitch line 4 is provided is attached to the surface 2 a of the base material 2 placed on the work table 6. As shown in FIG. 7, in the third step, the skin material 3 is arranged on the back side in order from the end (one end) 3 a side arranged on the worker X side with respect to the surface 2 a of the base material 2. Affixed toward the end (other end) 3b side.

  In the case of the present embodiment, stitch lines 4 are formed on the design surface 3 c of the end portion 3 a of the skin material 3 so as to follow the peripheral edge of the skin material 3. A backing portion (sewing portion) 4 a that bulges along the stitch line 4 is formed on the back surface 3 d of the portion where the stitch line 4 is formed. In the third step, when the skin material 3 is affixed to the surface 2 a of the substrate 2, first, the convex backing portion 4 a on the back side of the stitch line 4 is fitted into the groove portion 2 a 1 provided on the substrate 2. It is.

  In addition, as FIG. 1 shows, the stitch line 4 is formed not only from the edge part 3a side but from the side edge to the edge part 3b side. Therefore, when the skin material 3 is affixed to the base material 2, the backing portion 4a is also sequentially fitted into the groove portion 2a1 from the one end portion 3a side toward the other end portion 3b side.

  FIG. 8 is an explanatory diagram showing a state in which the work table 6 on which the base material 2 is placed is rotated so as to approach the worker X side. In the third step, the worker X changes the angle of the work table 6 as appropriate so that the skin material 3 can be easily pasted. When the work table 6 in the horizontal state shown in FIGS. 6 and 7 is changed to the inclined state shown in FIG. 8, first, the operator X steps on the switch 84 to operate the air cylinder 81. Then, the air cylinder 81 descends, and the meshing between the stop portion 82 attached to the tip of the air cylinder 81 and the gear 64 is eliminated. Then, the rotating shaft 63 provided in the main body 62 of the work table 6 becomes rotatable. At that time, the rotating shaft 63 is in a state in which the work table 6 (supporting part 61) can rotate in both directions, ie, the direction in which the work table 6 (supporting part 61) approaches the worker X side and the opposite direction (the direction away from the worker X). That is, the work table 6 is rotatable (swingable) in the front-rear direction as viewed from the worker X around the rotation shaft 63.

  The worker X can grip the handle 65 attached on the plate material 62 c of the main body 62 and rotate the main body 62. The worker X can rotate the work table 6 that has been in a horizontal state until then and appropriately change it to a desired angle so that the skin material 3 can be easily attached. When the worker X stops the work table 6 at a desired angle and operates the fixing means 8, the teeth of the stop portion 82 (dental row) and the teeth of the gear 64 (dental row) mesh with each other, The work table 6 is prevented from rotating.

  FIG. 8 shows the work table 6 rotated so as to approach the worker X side. However, in other embodiments, the work table 6 is moved away from the worker X. 6 may be rotated to change the angle of the work table 6 (the angle at which the work table 6 supports the base material 2).

  As described above, in the third step, the skin material 3 is attached to the surface 2 a of the base 2 while appropriately changing the angle of the work table 6. Even if the angle of the work table 6 is changed, the suspending means 9 can continue to apply tension to the skin material 3 following the rotation operation of the work table 6. That is, even if the angle of the work table 6 is changed, the suspension means 9 appropriately maintains the balance between the weight 92a and the skin material 3 at the changed angle, so that the skin material 3 is pulled up. It becomes a state.

  In addition, after the holding | maintenance part 91 is removed, the edge part 3b of the skin material 3 currently hold | maintained by the holding | maintenance part 91 is affixed on the surface 2a of the base material 2 similarly to the other part.

  FIG. 9 is an explanatory view showing a state in which the entire skin material 3 is adhered to the surface 2 a of the base material 2 using the covering auxiliary device 5. As shown in FIG. 9, after the entire skin material 3 is attached to the surface 2 a of the base material 2, the base material 2 is removed from the support portion 61 of the work table 6.

  Then, if necessary, the base material 2 and the skin material 3 are press-molded using a predetermined mold, and the base material 2 and the skin material 3 are completely bonded, as shown in FIG. The armrest part 1 is obtained.

  As described above, the covering auxiliary device 5 according to the present embodiment can fix the work table 6 by rotating it to a desired angle, so that the skin material 3 is attached to the surface 2a of the base material 2 having a curved surface. The workability of attaching the skin material 3 to the base material 2 is good.

  Moreover, the covering auxiliary | assistant apparatus 5 is provided with the suspension means 9, and is aligning the skin material 3 with the surface of the base material 2, and it arrange | positions the skin material 3 in order from the one end 3a to the other end 3b. It is easy to affix to 2a, and workability is further improved.

  In the covering auxiliary device 5, the suspending means 9 is connected to the holding portion 91 that holds the other end 3 b of the skin material 3 and the holding portion 91, and biases the holding portion 91 in a direction in which the skin material 3 is pulled. Since the urging means 92 is provided, it is possible to continue to apply tension to the skin material 3 following the rotational operation of the work table 6.
