Description

  The present invention, when manufacturing a rug that is configured to cover the surface and side surface of the floor material in the form of a plate with a front cover, the end portion of the front cover that protrudes laterally from the side surface of the floor material The present invention relates to a rug manufacturing apparatus which is folded back to the back side of the flooring.

  A rug, for example, a tatami mat, has a configuration in which the surface and side surfaces of a plate-like floor material (tatami floor) are covered with a tatami mat serving as a front cover. In recent years, this type of tatami mat has a configuration in which the end of the tatami surface is folded back to the back side of the flooring and fixed with an adhesive or the like. When manufacturing this type of tatami, when the end portion of the tatami surface that protrudes laterally from the side surface of the flooring is folded back to the back side of the flooring, it is conventionally performed as shown in FIG. (For example, refer to Patent Document 1).

That is, as shown in FIG. 15 (a), a mounting table 3 is provided on the upper side of the base 1 so as to be movable up and down by the guide 2. On the mounting table 3, the tatami table 4 and the plate-like flooring 5 Place. At this time, the flooring 5 is placed so that the side surface 5a of the flooring 5 and the side surface 3a of the mounting table 3 are flush with each other with the tatami surface 4 facing down, and the end 4a of the tatami surface 4 is The floor 5 is projected from the side surface 5a to the side.
Thereafter, the floor material 5 is pressed from above by the pressing body 7, and the floor material 5 and the tatami surface 4 are lowered together with the mounting table 3. In this case, as shown in FIG. 15B, since the weir body 6 is provided on the side of the mounting table 3 with a slight gap from the side surface 3a of the mounting table 3, it protrudes to the side. Further, the end 4a of the tatami mat 4 is brought into contact with the weir body 6 and bent along the side surface 5a of the flooring 5. In the state where the pressing body 7 is lowered to the lower limit (that is, until the lower surface of the mounting table 3 comes into contact with the upper surface of the stopper 1 a disposed on the base 1), It arrange | positions so that the powder-like hot melt 8 may be sprinkled.

Subsequently, the hot platen 9 provided on the weir body 6 side (right side) is advanced to the flooring 5 side (left side). At this time, a convex portion 9a protruding forward is formed on the upper portion of the heat plate 9, and the lower surface 9b of the convex portion 9a is moved forward so as to be slid against the back surface of the flooring 5. 4 is bent so as to be along the back surface side of the flooring 5 (see FIG. 15C). At this time, the hot melt 8 disposed at the edge of the flooring 5 is heated and melted by the lower surface 9b of the hot platen 9 while being covered by the end 4a of the folded tatami table 4. Then, the hot platen 9 is moved backward and the cooling body 10 is lowered (not shown), and forced cooling by the cooling body 10 is performed from above the end 4a of the folded tatami table 4. Thereby, once melted hot melt 8 is hardened, end 4a of tatami mat 4 is bonded to flooring 5 by hot melt 8.
JP 2005-120624 A

However, in the conventional manufacturing method described above, the following problems occur when the thickness of the flooring 5 changes. That is, when the hot platen 9 is moved forward to bend the end 4a of the tatami mat 4 to the back side of the floor material with respect to the thick floor material, the tip of the convex portion 9a has a wide side surface of the thick floor material. The advancing of the heating platen 9 is impeded and the folding process is interrupted.
On the other hand, when the hot platen 9 is moved forward with respect to the thin floor material, the tip of the convex portion 9a advances to the edge of the floor material, but the back surface of the thin floor material is separated from the lower surface 9b of the convex portion 9a. As a result, the end 4a of the tatami table 4 cannot be in close contact with the back surface of the flooring, and a good crease cannot be obtained.
For this reason, it is necessary to make the position of the back surface of the flooring constant by changing the stopper 1a corresponding to the thickness of the flooring to adjust the lower limit of the pressing body 7. However, every time the thickness of the flooring changes, the stopper 1a must be attached and detached, which makes the operation complicated.

  The present invention has been made in view of the above circumstances, and the purpose thereof is to determine the thickness of the flooring when manufacturing a rug that is configured to cover the surface and side surfaces of a plate-like flooring with a front cover. Regardless of the object, it is an object of the present invention to provide a rug manufacturing apparatus that can satisfactorily perform a folding operation of a front cover.

  In order to achieve the above object, a rug manufacturing apparatus according to the present invention provides a rug for manufacturing a rug having a structure in which the surface and side surfaces of a plate-like flooring are covered with a front cover. An end portion projecting sideways from the side surface of the flooring material is folded back to the back surface side of the flooring material, the front cover is on the lower side, and the end portion of the front cover is made of the flooring material. In a state of projecting from the side to the side, the table and the flooring are placed in a stacked state, and the flooring and the flooring and A presser part for pressing the front cover, a presser part driving means for moving the presser part in the vertical direction, and an angular bending means for bending the end part of the front cover protruding to the side along the side surface of the flooring. , Move up and down with the presser in the vicinity of the presser The end portion of the front cover that is moved on substantially the same plane as the back surface of the floor material and is bent by the corner bending means in a state where the presser portion presses the back surface of the floor material. It is the structure provided with the back folding means which has a bending part bent along the back surface of a flooring.

A reverse folding means having the bent portion is provided in the vicinity of the pressing portion so as to move in the vertical direction together with the pressing portion. For this reason, even if the thickness of the flooring changes, the bent portion can be positioned substantially on the same plane as the backside of the flooring by pressing the backside of the flooring with the holding part. it can. That is, according to the said structure, the relative positional relationship of the back surface of a flooring and the said bending part can always be maintained constant.
Therefore, when the end portion of the front cover is folded back to the back surface side of the floor material by the bent portion, the end portion of the front cover is brought into close contact with the back surface of the floor material regardless of the thickness of the floor material. Can be folded.

  According to the present invention, when manufacturing a rug configured to cover the surface and side surfaces of a plate-like flooring material with a front cover, the front cover is favorably folded regardless of the thickness of the flooring material. be able to.

It has become.

  Three air cylinders 19 are provided upward on the horizontal frame 18 located between the front vertical frames 12 and 12 slightly below the front mounting table 15, and the three air cylinders 19 A corner bending plate (a corner bending portion) 20 extending in the left-right direction is connected to the upper end portion of the rod. Specifically, as shown in FIG. 4, the square bending plate 20 is formed in an “L” shape and is in contact with the front end surface 15 a of the front mounting table 15 inside the upper end portion thereof. The air cylinders 19 are moved up and down. The corner bending plate 20 is configured such that the upper end of the corner bending plate 20 is positioned on the upper surface of the front mounting table 15 when the air cylinder 19 is lowered to the lower limit. This corner bending plate 20 constitutes the corner bending means of the present invention together with the three air cylinders 19 serving as corner bending portion driving means.

  Two attachment members 21 are fixed to the front end surface of the square bending plate 20, and a ruler 22 is attached to each of the attachment members 21 so as to be rotatable around a support shaft 21a. A reference portion 22 a that is long in the left-right direction is provided at the tip of the ruler 22. As shown in FIG. 4, when the ruler 22 is rotated and raised, the ruler 22 is flush with the end surface facing the rear (right side in the drawing) of the reference portion 22 a and the front end surface 15 a of the front mounting table 15. It is designed to be locked in position.

  The horizontal frame 23 slightly above the front mounting table 15 is fixed at both ends to an auxiliary frame 24 erected substantially in the middle between the front vertical frame 12 and the rear vertical frame 13. The horizontal frame 23 is provided with two air cylinders 25 facing downward, and a main presser plate 26 for floor presser is connected to the tip ends of the rods of the two air cylinders 25. . The main presser plate 26 has a substantially plate shape extending in the left-right direction, and is moved up and down by two air cylinders 25.

  A rail plate 27 is disposed on the front side of the front vertical frame 12 so as to be positioned above the front mounting table 15 and extend in the left-right direction. Guide members 29 having four rollers 28 are fixed to both ends of the rail plate 27, respectively. Specifically, as shown in FIGS. 5 and 6, the guide member 29 rolls the rail plate 27 by rolling the four rollers 28 with the front end of the vertical frame 12 sandwiched therebetween. It is configured to guide along the frame 12. The rail plate 27 is moved up and down by two downward air cylinders 30 provided on the top of the front vertical frame 12.

  The rail plate 27 is provided with a creasing roller 31 constituting a creasing means so as to be movable in the left-right direction. The creasing roller 31 is configured by integrally including a handle 32 that is rotatably provided at the front portion thereof, and a roller portion 33 that is rotatably mounted at a substantially central portion of the creasing roller 31. . When the creasing roller 31 is lowered to the lowering limit together with the rail plate 27 by the air cylinder 30 (see FIG. 7), the outer peripheral portion of the roller portion 33 is positioned along the front end surface 15a of the front mounting table 15. . In this state, when the operator operates the handle 32, the creasing roller 31 is moved in the left-right direction. This movement is performed in a state where the handle 32 is rotated in the direction of the arrow B and tilted horizontally (see a two-dot chain line in FIG. 7).

  On the other hand, as shown in FIG. 4, when the rail plate 27 is in the ascending limit, the height dimension H1 from the upper surface of the front mounting table 15 to the lower surface of the rail plate 27 is the height from the lower surface of the main presser plate 26. It is set to be larger than the dimension H2 (H1> H2), so that the rail plate 27 does not get in the way during the bonding work described later.

  A floor presser plate (presser part) 34 extending in the left-right direction is disposed at a height H1 position of the front vertical frame 12. Guide members 36 (see FIG. 2, FIG. 4, etc.) having four rollers 35 are fixed to both ends of the floor pressing plate 34, respectively. The guide member 36 rolls in a state where the four rollers 35 sandwich the rails 37 extending in the vertical direction provided respectively inside the vertical frames 12 and 12 at the front portion, so that the floor pressing plate 34 is moved. It is configured to guide along the rail 37. The floor pressing plate 34 is moved in the vertical direction by two downward air cylinders (pressing portion driving means) 39 provided on the upper horizontal frames 38 a and 38 b of the frame 11. .

  In the present embodiment, the floor pressing plate 34 is provided with a reverse folding means. The reverse folding means is composed of a folding plate (bending portion) 40 (see FIG. 5) and an air cylinder 41 for driving the folding plate (bending portion), and is moved in the vertical direction together with the floor pressing plate 34 by the air cylinder 39. It has come to be.

  That is, three air cylinders 41 are provided laterally on the upper surface of the floor pressing plate 34, and a bending plate 40 extending in the left-right direction is provided at the front end of the rods of the three air cylinders 41. Are connected. The folding plate 40 is formed in an “L” shape in which a long plate-like member is folded forward, and is moved in the front-rear direction by the three air cylinders 41. The lower surface 40a is configured to move on substantially the same plane as the lower surface of the floor pressing plate 34. When the bending plate 40 is advanced to the forward limit by the air cylinder 41, the lower surface 40a projects forward from the front end surface 15a of the front mounting table 15 (see FIG. 12). Note that the air cylinders 30, 39, etc. described above are provided with sensors. For example, as shown in FIG. 1, a sensor 39a is provided slightly below the center of the air cylinder 39, and the lowering position of the floor pressing plate 34 is detected by the sensor 39a.

  The frame 11 is provided with a control panel 42 located above the horizontal frame 38b. As shown in FIG. 1, an operation unit 43 having switches for operating the air cylinders 19, 25, 30, 39, and 41 is provided at the upper portion of the control panel 42. A power switch 44 and an automatic switch 45 of this apparatus are provided below 42.

  A control circuit such as a microcomputer (not shown) is accommodated in the control panel 42. The microcomputer stores a control program for driving and controlling the air cylinders 19, 25, 30, 39, and 41. That is, the microcomputer is configured to receive various switch signals from the operation unit 43, the power switch 44 and the automatic switch 45, a detection signal from the sensor 39a, and the like, and a predetermined air cylinder 19 , 25, 30, 39, 41 are configured to operate. Specifically, as will be described in the following description of the operation, each time the operator turns on the automatic switch 45, one of the air cylinders 19, 25, 30, 39, 41 is driven in a predetermined order. A series of manufacturing steps of the rug in the apparatus is executed step by step.

Next, the operation of the above configuration will be described with reference to FIGS. In addition, these figures show the side view of the principal part which fractures | ruptures and shows a part of the vertical frame 12 of the front part.
The tatami mat used as a rug is configured such that a tatami floor serving as a flooring material has a rectangular plate shape, and the surface and side surfaces of the tatami floor are covered with a tatami mat serving as a front cover. In the present embodiment, both sides of the tatami floor are formed in an inverted “C” shape in a side view (see FIG. 4). It is provided for reasons such as to ensure the ease of work when laying. When manufacturing such a tatami mat, the end portion of the tatami surface is folded back to the back side of the tatami floor and bonded as follows.

  First, as shown in FIG. 4, the tatami table 100 and the tatami floor 101 are arranged in a state where the tatami table 100 having a sheet shape is turned down and an end portion of the tatami table 100 is projected sideways from the side surface of the tatami floor 101. Are mounted on the mounting tables 15 and 16 in a state of being stacked. In this case, the end portion of the tatami surface 100 protrudes to the side longer than the thickness of the tatami floor 101, and reaches the back surface (upper surface in FIGS. 4 to 14) of the tatami floor 101 when folded. Have Then, the tatami surface 100 and the tatami floor 101 are moved so that the side surface of the tatami mat 100 comes into contact with the end surface of the reference portion 22a of the ruler 22, and the side surface of the tatami mat 100 is positioned so as to be along the front end surface 15a of the front mounting table 15. Let In addition, the tatami mat 100 and the tatami floor 101 are previously bonded (temporarily bonded) to the lower surface of the tatami mat 100 and the tatami floor 101 in order to prevent their mutual positions from shifting.

  In this state, by operating the automatic switch 45, the air cylinder 25 is actuated to lower the main presser plate 26, and the main presser plate 26 is brought into contact with the tatami floor 101 from above, so that the tatami surface 100 and The tatami floor 101 is pressed (see FIG. 5). Following this, the air cylinder 39 is actuated to lower the floor presser plate 34. In this case, the floor pressing plate 34 descends along the rail 37 together with the folding plate 40 while being guided by the guide member 29, and the floor pressing plate 34 and the folding plate 40 are moved toward the end of the tatami floor 101. The tatami mat 100 and the tatami floor 101 are pressed by contacting from above.

Thus, after fixing the tatami table 100 and the tatami floor 101 on the mounting tables 15 and 16, the operator rotates the ruler 22 in the direction of arrow A as shown in FIG.
Then, by operating the automatic switch 45 again, the air cylinder 30 is operated and the rail plate 27 is lowered. In this case, the rail plate 27 descends along the front vertical frame 12 together with the creasing roller 31 while being guided by the guide member 29, and the outer peripheral portion of the roller portion 33 contacts the tatami mat 100 (see FIG. 7). In this state, the operator tilts the handle 32 horizontally and operates the handle 32 to move the creasing roller 31 in the left-right direction. At this time, the roller unit 33 rotates along the side surface of the tatami floor 101 and rotates to make a line on the tatami surface 100. When the creasing roller 31 is not used, the handle 32 is raised to the original vertical state.

  Thereafter, by operating the automatic switch 45, the air cylinder 30 is operated to raise the rail plate 27 along with the creasing roller 31 along the vertical frame 12, and return to the original standby position (see FIG. 8). . Then, the worker applies an adhesive to the back surface (upper surface in FIG. 8) of the end portion of the tatami surface 100 that protrudes laterally from the side surface of the tatami floor 101. This application is performed, for example, by discharging a liquid hot melt as an adhesive that solidifies without heating from a hot melt gun (not shown).

  When the application of the adhesive is finished and the automatic switch 45 is operated, the air cylinder 19 is actuated to raise the square bending plate 20 (see FIG. 9). As a result, the end portion of the tatami mat 100 that protrudes from the side surface of the tatami floor 101 is bent vertically along the streaks attached by the creasing roller 31. The rising amount of the corner bending plate 20 is set to be smaller than the thickness of the tatami floor 101.

  Subsequently, the air switch 39 is operated by operating the automatic switch 45 to raise the folding plate 40 and the floor pressing plate 34 along the rail 37 and return to the original standby position (see FIG. 10). ). And hot melt is apply | coated to the back surface of the edge part of the tatami floor 101 using the said gun for hot melt.

  Thereafter, when the automatic switch 45 is operated, the air cylinder 39 and the air cylinder 41 are operated in the following order, and the end of the tatami mat 100 is bent along the back surface of the tatami floor 101. That is, first, the air cylinder 39 is actuated to lower the floor pressing plate 34 along with the folding plate 40 along the rail 37. At the time of the lowering, the air cylinder 41 is operated to advance the bending plate 40 to the forward limit (see FIG. 11), and the lowering position of the floor pressing plate 34 is detected by the sensor 39a.

  Then, as shown in FIG. 12, the floor pressing plate 34 presses the vicinity of the end of the tatami floor 101 from above while the folding plate 40 is positioned in front of the end of the tatami mat 100 that is bent vertically. .

  In addition, when a predetermined time elapses after the lowering position of the plate 34 is detected by the sensor 39a, the air cylinder 41 is operated and the folding plate 40 is moved backward. At this time, the floor presser plate 34 is positioned at the lower limit where the back surface of the tatami floor 101 is pressed, and the lower surface 40a of the folding plate 40 is in close contact with the end of the tatami surface 100 and is attached to the back surface of the tatami floor 101. The end of the tatami surface 100 is pressed against the back side of the tatami floor 101 (see FIG. 13). Thereby, the edge part of the tatami surface 100 is adhere | attached in the state closely_contact | adhered to the side surface and back surface of the tatami floor 101 by the hot melt applied to the edge part of the tatami surface 100, and the back surface of the tatami floor 101.

  When the automatic switch 45 is operated after the hot melt is solidified after a predetermined time has elapsed, the air cylinder 39 is activated to raise the floor pressing plate 34 together with the folding plate 40 (see FIG. 14). Further, by operating the switch 45, the air cylinder 19 is operated to lower the square bending plate 20, and the air cylinder 25 is operated to raise the main presser plate 26 to hold the tatami mat table 100 and the tatami floor 101. Is released. By the above, the process of adhere | attaching one edge part of the tatami surface 100 to the back surface of the one side part of the tatami floor 101 is complete | finished. After that, a process of bonding the other end of the tatami surface 100 to the back surface of the other side of the tatami floor 101 is performed, but the description is omitted because this process is performed in the same manner as the above bonding.

According to the above embodiment, the following effects can be obtained.
The bending plate 40 and the air cylinder 41 for operating the bending plate 40 are provided so as to move in the vertical direction together with the floor pressing plate 34. For this reason, even if the thickness of the tatami floor 101 changes, the folding plate 40 can be made substantially flush with the back surface of the tatami floor 101 by pressing the back surface of the tatami floor 101 with the floor pressing plate 34. Can be positioned. In other words, the relative positional relationship between the back surface of the tatami floor 101 and the folding plate 40 can always be kept constant, so that the setup work when the thickness of the tatami floor 101 changes is unnecessary. it can.

  In the conventional rug manufacturing apparatus described in Patent Document 1 (referred to as a conventional apparatus, see FIG. 15), the back surface of the flooring 5 and the hot platen 9 when the setup work is not properly performed. There has been a situation where the lower surface 9b of the first and second lower surfaces 9b are separated from each other. For this reason, when the tatami mat 4 is bent, the end 4a of the tatami mat 4 is loosened. In this state, the tatami mat 4 and the flooring 5 are bonded to each other, and there is a fear that the value as a product is lowered. In particular, when the slope of the side of the flooring 5 is formed, the above-mentioned slack is likely to occur.

On the other hand, according to the present embodiment, when the end of the tatami mat 100 is folded to the back side of the tatami floor 101, the lower surface 40 a of the folding plate 40 is in close contact with the end of the tatami mat 100 and is attached to the tatami floor 101. Since it moves while being pulled along the back surface, the end of the tatami surface 100 can be bonded to the back surface of the tatami floor 101 without causing the tatami surface 100 to be slack.
In addition, since the tatami mat 100 that protrudes from the tatami floor 101 is provided with the creasing roller 31 for adding a folding line along the outer shape of the tatami floor 101, the tatami mat 100 can be folded well. As a result, adhesion of the tatami surface 100 can be performed satisfactorily.

  When the end portion of the tatami mat 100 protruding from the side surface of the tatami floor 101 is bent vertically, in the conventional apparatus (see FIG. 15), the floor member 5 is pressed from the upper side by the pressing body 7 and the floor member 5 and the tatami mat table 4 are placed. All three had to sink. On the other hand, according to the present embodiment, it is only necessary to raise the corner bending plate 20 by the air cylinder 19, so that the configuration in which the end portion of the tatami mat 100 is bent vertically can be simplified.

Further, since the vicinity of the end portion of the back surface of the tatami floor 101 can be pressed by the floor pressing plate 34, it is possible to suppress warping of the end portion of the tatami floor 101 due to the rising of the square bending plate 20.
Positioning of the tatami floor 101 on the mounting tables 15 and 16 can be performed simply by bringing the rotatable ruler 22 and the end surface of the tatami floor 101 into contact with each other, so that workability can be improved.

The present invention is not limited to the above-described embodiments, and can be modified or expanded as follows.
The means for bonding (bonding) the end of the tatami surface 100 to the tatami floor 101 is not limited to hot melt or other adhesives. That is, when the end of the tatami mat 100 is folded back to the back surface of the tatami floor 101, the end of the tatami mat 100 and the tatami floor 101 may be coupled using a stapler or double-sided tape. A hot melt gun is provided on the rail plate 27 so as to be movable, and a control means for operating the hot melt gun, the creasing roller 31 and the ruler 22 is provided. You may comprise so that the series of manufacturing processes of the rug in this apparatus may be performed.
The object of the rug may be anything other than a tatami mat as long as it has a structure in which the surface and side surfaces of the floor material having a plate shape are covered with a front cover.
