Description

  The present invention relates to an automatic wallpaper pasting machine that continuously applies glue to the back surface of a sheet-like wall covering material affixed to an indoor wall surface or the like, and in particular, the pulling load of the wall covering member inlet is constant. The present invention relates to a slitter set in a range and an automatic wallpaper pasting machine having the slitter.

  At present, wall coverings are applied to interior wall surfaces in the interior construction of buildings by applying glue continuously to sheet-like wall coverings (so-called “cross”) using a dedicated wallpaper glue machine on site. It has become common to do it. As such a wallpaper pasting machine, an automatic pasting machine has recently been widespread. In this automatic wallpaper pasting machine, the rotating shaft of a drive mechanism such as a motor is connected to the rotating shaft end of the pasting roll, and the other rolls are interlocked via a gear by rotating the pasting roll electrically. While the cloth is automatically conveyed by the rotation of these rolls, the glue is scooped up from the glue and applied to the back of the cloth.

  In such a conventional wallpaper pasting machine, usually the cloth is fed out from a roll roll that is pivotally supported on the rear side of the pasting machine main body, and via a tension bar that is bridged by a leg that supports the main body. Are transported and introduced into a slitter.

  However, in such a conventional wallpaper pasting machine, since the tension bar is pivotally supported at a leg part, that is, at a position obliquely below the slitter, the cloth is conveyed to the drawing port on the rear part of the pasting machine main body. When trying to do so, the cross may be wrinkled, bent, etc. before it is transported to the slitter. In this state, if the cross is cut by transporting to the slitter, the side edge of the cross There was a problem that it could not be cut well.

  In particular, an over cutter (upper blade) and an under cutter (lower blade) constituting a pair of upper and lower rotary blades are respectively positioned at opposite positions of the upper and lower shafts provided parallel to the direction perpendicular to the conveying direction of the cloth. In the case of a slitter that is clamped and cut by sandwiching a sheet-like cloth from which the pair of cutters are conveyed from above and below, when the cloth is loosened and conveyed to the pair of cutters, the cloth enters between the blades. In this case, a straight cut edge could not be obtained, and a gap (through) was sometimes generated in the cross joint during construction.

  Furthermore, as the pasting operation proceeds and the cloth is gradually fed out from the original roll, the number of turns of the original roll decreases accordingly, so that the weight of the original roll decreases. For this reason, the original fabric roll cannot fully resist the pulling force of the cloth into the main body, and the amount of axial rotation of the original fabric roll exceeds the amount of pulling in the cloth. For this reason, the cloth is unnecessarily drawn out from the raw roll, and the cloth is loosened to reduce the pulling load. Therefore, there arises a problem that wrinkles and deflection are generated in the cross being conveyed, and the cross meanders.

  In response to such problems, the present applicant has proposed a number of improvements to the wallpaper pasting machine. For example, a wallpaper pasting machine has been proposed in which a constant tension is applied to the cloth to prevent the cloth from wrinkling and bending and to prevent the cloth from meandering (see, for example, Patent Document 1). Further, a wallpaper pasting machine has been proposed that can press down the cloth from the surface side and prevent the cross from meandering and wrinkling (for example, see Patent Document 2).

JP2001-340795 JP2002002199A

  However, in these proposals, a force perpendicular to the cross surface is applied to the cross with respect to the cross conveyance direction. Specifically, the cross being conveyed is sandwiched from both sides to apply braking, and the cross is applied to the cross. A brake that consists of a pair of rod-like members that give a predetermined tension and an elastic member that urges them, and a brake that resists the pulling force of the cloth by pressing the raw roll from the outside with a plate-like member. The force perpendicular to the cross surface that is applied locally may result in problems such as scratches on the back of the cross, scratches on the cross surface, and damage to the cross itself.

  In addition, with the decrease in the weight of the cloth as the number of turns of the cloth becomes smaller, it is undeniable that the cloth is meandering and wrinkled, especially in soft cloth. There was a situation that had to be multiplied.

  The present invention has been made in view of such problems, and even if the number of turns of various fabric rolls such as a hard cloth, a soft cloth, a heavy cloth, and a light (thin) cloth is reduced, It is possible to prevent the wrinkles, bends, etc. from occurring on the cloth, and to perform satisfactory gluing construction, to reliably cut the side edge of the cloth, and to be optimal for various kinds of cloth An object is to provide an automatic wallpaper pasting machine or a slitter for an automatic wallpaper pasting machine that can be changed to conditions.

The automatic wallpaper pasting machine according to the invention described in claim 1 is a glue paster main body for the wall covering cut while cutting both edges of the sheet-like wall covering fed out from the raw roll with a rotary blade.

A rotation center for holding each bar holding piece oppositely at a position deviated from the fixed holding portion of the tension bar;
And a stopper mechanism for fixing the tension bar fixedly held on the bar holding piece around the rotation center at a position where an inner angle of the bent conveyance path is 90 ° or less. .

In the automatic wallpaper pasting machine according to the invention described in claim 3, the stopper mechanism according to claim 2 is
A hole formed in either one of the wall surface disposed on both ends of the tension bar and the bar holding piece;
It is characterized in that it has an insertion pin formed in either one of the holes inserted into the hole.

The slitter for an automatic wallpaper pasting machine according to the invention described in claim 4 draws in a sheet-like wall covering material fed from a raw roll from a pinch roll of a pull-in port at the rear of the pasting machine main body, It is attached to the rear part of an automatic wallpaper pasting machine that applies glue on the back surface of the wall covering material and feeds it to the front part of the wall covering material by a glued roll provided on the sheet, and cuts both edges of the sheet-like wall covering material that is pulled in. In the slitter for automatic wallpaper pasting machine,
A guide surface that is formed on the upstream side of the wall blade material conveyance of the rotary blade and guides the wall material to the rotary blade;
A curved surface portion formed on the conveyance upstream end edge portion of the guide surface;
A tension bar that bends the conveyance path along the curved surface,
A fixing mechanism capable of changing the fixing position of the tension bar so that the inner angle of the conveyance path bent along the curved surface portion can be changed to one or more predetermined angles of 90 ° or less. It is a feature.

  In the present invention, as described above, even when the number of windings of the raw rolls of various crosses such as a hard cloth, a soft cloth, a heavy cloth, and a light (thin) cloth is reduced, wrinkles, bending, etc. occur in the cloth. Automatic wallpaper glue that can cut the edges of the cloth reliably and can be changed to the optimum tension state according to various cloths. There is an effect that a slitter for a machine or an automatic wallpaper pasting machine can be obtained.

  In the present invention, a guide surface that is formed on the upstream side of the wall material conveyance of the rotary blade and guides the wall material to the rotary blade, a curved surface portion that is formed on the conveyance upstream edge of the guide surface, and the curved surface A tension bar that bends the conveyance path along the portion, and a fixed position of the tension bar that can change the inner angle of the conveyance route bent along the curved surface portion to one or more predetermined angles of 90 ° or less The pull-in load at the pull-in port is greater than 12.748645N (1.3kg weight) when the weight of the roll is included and the weight of the roll is included. The pinch roll with the full width of the mouth is smaller than the pull-in load that slips. For this reason, even if the number of rolls of various cloths such as a hard cloth, a soft cloth, a heavy cloth, and a light (thin) cloth is reduced, wrinkles, bending, etc. are prevented from occurring in the cloth, Good gluing can be performed, and the cross side edge can be cut reliably.

  In addition, various crosses are provided by a fixing mechanism that can change the fixing position of the tension bar so that the inner angle of the conveyance path bent along the curved surface portion can be changed to one or more predetermined angles of 90 ° or less. Accordingly, an automatic wallpaper pasting machine or a slitter for an automatic wallpaper pasting machine that can be changed to an optimum condition according to the above can be obtained.

  Specifically, in the present invention, in an existing automatic wallpaper pasting machine, a phenomenon in which wrinkles are likely to occur as the number of turns of the cloth cloth decreases is analyzed. That is, it was verified how much pulling load is generated only with the attached tension bar with various cloths in a state in which the cloth is loosened. As a result, it was found that the soft cloth and the light and thin slippery cloth cannot prevent wrinkles from being generated only by the pulling load generated only by the tension bar attached to the existing automatic wallpaper pasting machine.

  On the other hand, the maximum allowable load of various crosses is surprisingly high, and even if the load is such that the full width pinch roll slips, it will not be damaged. It was found that if the weight was 15 kg or less, even a light and thin slippery cloth would not slip.

  From the above, the pull-in load of the pull-in port in the state in which the cloth fed from the raw roll is slackened is larger than that of the conventional automatic wallpaper pasting machine, and the pull-in pin that pulls in the pull-in port By making it smaller than the load, even if the number of rolls of the various cloth rolls decreases, it is possible to prevent the cloth from wrinkling, bending, etc., and to perform good gluing construction The cross side edge can be cut reliably with a slitter.

  Specifically, the pull-in load of the pull-in port is larger than 12.748645N (1.3 kg weight) when the weight of the raw fabric roll is not included, and the pinch roll at the pull-in port slips when the weight of the raw fabric roll is included. If it is made smaller than the pull-in load, unlike the existing automatic wallpaper pasting machine, even if the cloth fed out from the original roll is loosened, both edges are cut and wrinkled. In addition, there is no occurrence of bending or the like, and satisfactory gluing can be performed. In addition, there are various kinds of soft cloths that are prone to wrinkles and crosses that are slippery. In such cloths, it is preferably 16.671305N (1.7 kg weight) or more, and 147.09975N (15.0 kg weight). ) No wrinkle if below.

  That is, in the present invention, a curved surface portion formed on the upstream end edge portion of the guide surface which is formed on the upstream side of the wall blade material conveyance of the rotary blade and guides the wall material to the rotary blade, and along the curved surface portion. When the inner angle of the conveyance path bent along the curved surface portion is set to 90 ° or less by the tension bar that bends the conveyance path, the pull-in load does not include the weight of the original roll. It was found that it was larger than (1.3 kg weight) and smaller than the pulling load at which the pinch roll of the full width of the pulling inlet slips when including the weight of the raw roll.

  However, in the present invention, the fixing mechanism that can change the fixing position of the tension bar so that the inner angle of the conveyance path bent along the curved surface portion can be changed to one or more predetermined angles of 90 ° or less. Thus, it is possible to change to an optimum condition according to various crosses. It should be noted that the predetermined angle includes one to include removing the tension bar from the fixed position when the cloth is attached and changing the angle to a predetermined angle when gluing. In addition, as long as optimum conditions are included according to various crosses, a plurality of predetermined angles may be provided.

  As the fixing mechanism of the present invention, the fixing position of the tension bar can be changed so that the internal angle of the conveyance path bent along the curved surface portion can be changed to one or more predetermined angles of 90 ° or less. If it is. As a specific mode, the fixing mechanism holds the bar holding pieces for fixing and holding both ends of the tension bar, and the rotation for holding the bar holding pieces facing each other at a position removed from the fixing holding position of the tension bar. And a stopper mechanism for fixing a tension bar fixedly held by the bar holding piece around the rotation center at a position where an inner angle of the bent conveyance path is 90 ° or less.

  The stopper mechanism of the present invention may be any mechanism as long as the inner angle of the bent conveyance path is fixed at a position of 90 ° or less. As a specific aspect, the stopper mechanism is formed in one of the wall formed on either side of the tension bar and the hole for holding the bar holding piece, and on the other inserted through the hole. And an inserted insertion pin.

  The inner angle of the bent conveyance path of the present invention may be bent by 90 ° or more when viewed from the conveyance route of the cloth, and the inner angle of the bent portion may be 90 ° or less as a result, preferably 90 ° or less. What is necessary is just to provide one or more bending places which are 77 degrees or more, More preferably, it is 85 degrees or less 77 degrees or more.

  Therefore, as a preferred embodiment, the automatic wallpaper pasting machine of the present invention has an inner angle of 90 ° or less in the bent conveyance path among the conveyance paths of the sheet-like wall covering material from the raw fabric roll to the inlet. As long as it contains. More preferably, a guide surface that is formed on the upstream side of the wall blade material conveyance of the rotary blade, guides the wall material to the rotary blade, a curved surface portion formed on the conveyance upstream side edge portion of the guide surface, A tension bar that bends the conveying path along the curved surface portion, and an inner angle of the conveying path that is bent along the curved surface portion is 90 ° or less. It is possible to enter the previous load range by the conveyance path bent to 90 ° or less, and in some cases, it is possible to reduce other existing tension bars.

  Further, in the slitter for automatic wallpaper pasting machine of the present invention, the sheet-like wall covering material fed out from the raw roll is drawn into the inside from the pinch roll at the drawing port at the rear of the pasting machine main body, and the glue provided in the main body is provided. Automatic wallpaper pasting machine that is attached to the back of an automatic wallpaper pasting machine that applies glue to the back of the wall covering by a roll and sends it to the front of the main body and cuts both edges of the drawn sheet-like wall covering In the slitter for use, formed on the upstream side of the wall blade material conveyance of the rotary blade, a guide surface for guiding the wall material to the rotary blade, and a curved surface portion formed on the conveyance upstream end edge of the guide surface, A tension bar that bends the conveying path along the curved surface portion, and an inner angle of the conveying path that is bent along the curved surface portion can be changed to one or more predetermined angles of 90 ° or less. Fixed position can be changed And a fixing mechanism that. This makes it possible to enter the described load range by installing it on an existing automatic wallpaper pasting machine, and there is also an advantage that it is possible to fully implement it without purchasing a new automatic wallpaper pasting machine .

  Further, the slitter fixing mechanism can have the same configuration as the automatic wallpaper pasting machine described above.

Example 1. Measurement of pull-in load and maximum allowable load With respect to various crosses used in interior construction, the pull-in load was measured using a commercially available automatic wallpaper pasting machine. Moreover, the load when the pinch roll slipped was measured for each cross. The maximum allowable load is just before the load causing this slip. Furthermore, pasting was performed in a state in which the cloth cloth was loosened, and it was confirmed whether or not wrinkles were generated. Moreover, the shift | offset | difference after 4 m glueing at the time of mounting | wearing with the cross | deviated from the center position was measured.

  Specifically, as shown in Table 1, the cloth is (1) a hard cloth cloth, (2) a soft cloth cloth, (3) a heavy cloth with diatomaceous earth in the surface layer, and (4) a thin and light cloth. Adhesive paper (core sheet), (5) light and thick cloth made of foamed resin, and (6) general vinyl cloth were used. The width of each cross was all effective. As the automatic wallpaper pasting machine, machine A (trade name “TS Reserve RUN2001” (manufactured by Yayoi Chemical Co., Ltd.)) and machine B (trade name “Prime-SD” (manufactured by Kyokuto Sangyo Co., Ltd.)) were used.

  The pull-in load measures how much force is applied only with the attached tension bar in the state where each cloth original is loosened, so the cloth drawn from the cloth original is applied to the two attached tension bars. It was hung and only a spring was attached to one end. After loosening the original cloth, one end was pulled from the vicinity of the inlet through the spring alone, and the force just before the loose original cloth was pulled was measured.

  The maximum allowable load is to measure the load when the full-width pinch roll slips, so that only a spring is attached to one end of the cross cut to a length of about 1 m, and the other end is glued. After loading the main body and driving the gluing machine, one end was gradually pulled only through the spring, and the load at which the pinch roll of the gluing machine main body slipped was measured. The maximum allowable load is just before the load causing this slip.

After setting the cloth on the gluing machine as usual, the wrinkles were subjected to 4 m gluing in a state where the cloth was always loosened to check whether wrinkles were generated. In addition, the meandering was measured after 4 m glue was attached when the cloth was mounted with the cloth shifted from the center position. The results are shown in Table 2 below. Note that the values of the pull-in load and the maximum allowable load both indicate kg weight, and when the force is expressed in SI units, the gravitational acceleration g (9.80665 m / s ² ) is applied to these values. The drawing load in parentheses is the load when the weight of the original roll is included (the load when the original roll is not slackened). The inability to measure the meander indicates that the amount of movement exceeds 20 mm.

  As shown in Table 2, it was found that the pull-in load by the existing tension bar differs depending on the type of cloth. In addition, it was found that the pulling load is often high with a heavy cloth or a hard cloth, and varies depending on the state of the surface in contact with the tension bar. Moreover, as the cloth which is easy to generate wrinkles, the soft cloth made of vinyl (soft) and the foamed resin is overwhelming, and these cloths generate wrinkles even if the pulling load exceeds 1 kg weight. There was also a thing. The pull-in load of the existing tension bar of the commercially available automatic wallpaper pasting machine was 1.3 kg weight.

  It was also found that there was a difference in the maximum allowable load depending on the type of cloth. However, the maximum allowable load is unexpectedly high, and if it is 15 kg or less in all crosses, there will be no slip, and there will be no crosses torn before slipping. It turns out that there is no. That is, it has been found that there is no problem even if the pulling load in the existing automatic wallpaper pasting machine is greatly increased. Since there is no load exceeding 6.5kg weight even when the raw fabric roll is not slackened, it can be adequately handled even if a pulling load more than double the current load is generated at the pulling port of the gluing machine. I understood.

  From the above, the cloth drawn out from the roll is loosened so that the pull-in load of the draw-in port without including the weight of the roll is larger than that of the conventional automatic wallpaper pasting machine, Even if the number of turns of the various fabric rolls is reduced by making it smaller than the pull-in load at which the pinch roll of the pull-in port slips in the state including the weight of the anti-roll, wrinkles, bending, etc. occur in the cross. This can be prevented, a satisfactory gluing operation can be performed, and the cross side edge portion can be surely cut with a slitter.

FIG. 2 is an explanatory view showing a configuration of a main part of FIG. 1, in which FIG. 2a is an exploded view and FIG. 2b is an assembly view. 3 is a cross-sectional view of the main part of the slitter-side bearing plate showing the mounting structure of the bar holding piece shown in FIG. As shown in FIG. 1, the automatic wallpaper pasting machine includes a lower structure 2 in which a glue basket 4 for storing glue is installed, an upper structure 3 that is openable and closable with respect to the lower structure 2, and a lower structure. 2 and the leg part 31 which supports 2 mainly.

  In the lower structure 2, a lower pinch roll 6 having a full width for feeding the cloth C into the gluing machine main body 1 from the rear side and feeding it to the gluing roll 8, and the glue in the gluing pad 4 for gluing roll 8 A glue raising roll 13 for transferring to the cloth, a glue roll 8 for applying glue on the back of the cloth, a doctor roll 7 for adjusting the amount of glue in contact with the glue roll 8, and an appropriate tension applied to the cloth C The leveling rolls 9 fed out in the direction of the part are pivotally supported on the side plate of the glue basket 4 or a bearing plate parallel to the side plate so as to be interlocked with each other via a gear and arranged in parallel at a predetermined interval.

  On the other hand, the upper structure 3 is paired with the lower pinch roll 6 to form a pinch roll and has a full width upper pinch roll 10 having a measuring function, and a roll arranged in the lower structure 2. A drive roll 12 that is linked via a gear to apply a feeding tension to the cloth C toward the front of the pasting machine body, and a presser that presses the cloth C from above between the upper pinch roll 10 and the drive roll 12. The stays 11 are pivotally supported by the main body side bearing frames of the upper structure 3 so as to be arranged in parallel with each other at a predetermined interval. Moreover, the slitter 20 which cuts the both-sides edge of a cross is attached to the rear surface side of the lower structure 2 so that attachment or detachment is possible.

  In addition, a pair of legs 31 that support both side edges of the lower structure 2 are crossed out from a raw roll 40 that is passed through a central axis through a cross core rod 41 supported at the tip of a cross receiving bracket 42. A first tension bar 32 that is in contact with C and applies a pulling load at the pulling port of the pasting machine body is bridged. Above that, a second tension bar 33 is also bridged, which similarly contacts the cross C and applies a pulling load at the pulling port. Further, a third tension that applies a pulling load at the pulling port by abutting against the cloth C at the front lower side of the understay 21 that constitutes a guide surface for guiding the cloth C disposed in the slitter 20 thereabove to the rotary blade. Bar 34 is bridged.

  The third tension bar 34 is configured so that the inner angle between the guide surface of the understay 21 and the conveyance path toward the tension bar 34 can be changed in two stages. Specifically, as shown in FIGS. 2 and 3, both end portions of the third tension bar 34 are each tubular, and a pin member 36 having an insertion pin 35 at the tip is provided in each tube. It is slidably mounted in the tube. Each pin member 36 is urged outward by an urging spring 38 fixed by a latch pin 37 inside the tube. At both ends of the tension bar 34, a bar holding piece 39 having an insertion hole 35a of an insertion pin 35 is stopped by two screws 29a and 29b so that the pin member 36 does not deviate outside the tube.

  The bar holding piece 39 has an elliptical shape, and a fixing screw hole 28 is formed at a position facing the insertion hole 35a formed in one of the long diameters. A fixing screw 27 is inserted into the screw hole 28 via a rotating cylinder 26 and is fixed to be opposed to the inner walls of the slitter-side bearing plates 25 disposed on both ends of the third tension bar 34. . As a result, the tension bar 34 can move in parallel with the other frames or bars on the arc with the fixing screw 27 as the rotation center. Two latching holes 24 through which the insertion pins 35 at both ends of the tension bar 34 are inserted are formed on the inner wall side of the slitter both side bearing plates 25, and the insertion pins are inserted into the opposing latching holes 24. By inserting 35, the third tension bar 34 is fixed in parallel to the longitudinal direction of the slitter. In this case, the inner angle between the understay 21 and the third tension bar 34 can be changed to, for example, 77 ° or 85 ° depending on which of the two retaining holes 24 is fitted with the insertion pin 35. is there.

  The third tension bar 34 slides the operation piece 36a of the pin member 36 protruding from the slit 34a formed to face each side surface of both ends of the tension bar in the center direction of the bar, thereby inserting the insertion pin 35. By being pulled in, the fixing can be released from the retaining hole 24. Since the third tension bar 34 is rotatably fixed to the slitter by the fixing screw 27 via the bar holding piece 39, the third tension bar 34 does not fall off.

  In the present invention, the third tension bar 34 disposed in the slitter 20 immediately before the drawing-in opening is disposed in front of the understay 21 and the cross C extends from the third tension bar 34 along the rear edge of the understay 21. Therefore, the pulling-in load of the pulling-in port in the state where the cloth fed out from the raw roll at the pulling-in port is slackened is larger than 1.3 kg weight, and the pinch roll at the pulling-in port Apply a retraction load smaller than the retraction load that slips.

  With respect to the automatic wallpaper pasting machine shown in FIG. 1, the pulling load and the maximum allowable load were measured in the same manner as in Example 1. The results are shown in Table 3. The six types of cloth used were the same as those used in Example 1. Other operations and conditions are the same as those in the first embodiment.

  As shown in Table 3, the pull-in load of the pull-in port with the cross fed from the original fabric roll loosened (the load when the conveyance path is bent between the three tension bars and the rear edge of the understay) ) Was the lightest and lightest core sheet that was slippery and weighed 1.7 kg, and the largest pulling load was 6.0 kg heavier with a woven hard cloth. In addition, the pull-in load when including the weight of each original fabric roll was 4.0 kg heavy at the minimum and 9.5 kg heavy at the maximum, and it did not reach the pull load enough to cause slipping in any cross. .

  In Table 2, the softest cloth made of vinyl and the cloth made of foamed resin, which are most likely to be wrinkled, showed no wrinkles, and the meandering distance was 4 mm or less.
