Description

  TECHNICAL FIELD The present invention relates to a wallpaper pasting machine that continuously applies glue to the back of a wall covering when, for example, a sheet-like wall covering is applied to an indoor wall surface, and in particular cuts the side edge of the wall covering. The present invention relates to a wallpaper cutting device and a cartridge with a built-in rotary blade for the cutting device, which are adjusted to a predetermined width and then supplied to a gluing machine.

  Conventionally, when applying wall coverings to interior walls during interior construction, a wall paper pasting machine is used, and a long sheet-like wall covering is drawn from the back of the pasting machine main body and pulled out from the front. The paste is continuously applied to the back side. Also, in many cases, such a wallpaper pasting machine is equipped with a wall covering material cutting device at the back of the main body, and the side edge of the wall covering is placed in the transport direction before drawing the wall covering into the pasting machine body. Along with this, it is cut in advance and adjusted to a desired wall covering width.

  A general cutting device cuts wall coverings with a rotary blade. The rotary blade is driven using a drive force on the gluing machine main body or a small motor dedicated to cutting. There is a type that performs cutting by mounting a device and conveying the wall covering material while pressing the wall covering material from one side to the edge of a single rotating blade rotated at high speed.

  The configuration in which this single rotary blade is rotated at a high speed by a dedicated motor is for reducing the burden on the drive system on the gluing machine main body side and performing the gluing operation more smoothly. It is exposed to the outside and can be easily attached and removed without touching the rotating blade directly in the housing so that it can be safely replaced when the rotating blade must be replaced due to wear on the blade edge. Such a cartridge type has been developed (for example, see Patent Document 1).

  As such a cartridge with a built-in rotary blade, for example, as shown in FIG. 4, a rotary blade 102 supported by a shaft 103 is housed in a cutter box 101 formed of a housing type housing, and the rear side of the cutting device is cut after cutting. Some of the wall covering material side edges are covered with a guide member 104 for leading the outside edge of the apparatus. The guide member 104 is attached to the cutter box 101 so as to form a passage through which wall covering material conveyed for cutting can pass through the rotary blade portion.

  In this rotary blade built-in cartridge 100, the shaft 103 is pivotally supported at one end on the inner surface of the side wall of the cutter box 101. When the cutter box 101 is attached to a predetermined position of the cutting device, the other end is a motor 300 as a drive source. The rotary blade 102 rotates at a high speed by the rotational force transmitted from the rotary shaft 301 to the shaft 103 when the motor 300 is driven.

  In addition, the motor 300 is fixed to a slide bracket that is slidably mounted in the body width direction of the cutting apparatus that matches the wall covering width direction along the guide stay 110 formed in the housing of the cutting apparatus body. By being housed and fixed in the bracket 302 and connected to the motor 300, the cartridge 101 with a built-in rotary blade can be slid in the apparatus width direction integrally with the motor bracket 302 and the motor 300, and the cartridge 100 can be adjusted by adjusting the slide movement amount. The cutting position of the stored rotary blade 102 can be adjusted.

  As a position adjustment mechanism in this case, a slit opening is provided in the guide stay of the cutting device main body along the width direction of the main body, and a tightening screw having an operation knob is connected to the slide bracket through the slit opening, and the tightening screw is tightened by the operation knob. Generally, the slide bracket and the motor 300 are fixed to the guide stay by tightening the guide stay with respect to the guide stay, and the operation knob can be slid along with the slide bracket while the tightening screw is loosened by the rotation of the operation knob. is there.

  Further, the support of these cutting mechanisms does not rely only on the slide bracket, but a structure that supports from the side of the cartridge 100 with a built-in rotary blade is adopted from the viewpoint of overall movement and fixing stability. The rotary blade built-in cartridge 100 is supported by a clamping screw 107 having an operation knob 106 via a fixing bracket 105 fixed to the cutter box 101 with a screw at a position corresponding to the guide stay 110 of the cutting device body. When the operating knob 106 is rotated and the fastening screw 107 is screwed, the fixing bracket 105 is connected to the fixing tool 108 slidably fitted in the slide opening 111 formed along the width direction. The guide stay 110 is pressed and clamped to the fixture 108 to obtain a tightened fixed state. When the operation knob 106 is rotated to loosen the screwing of the tightening screw 107 to the fixture 108, the fixed state of the fixing bracket 105 is released. The fixing bracket 105 together with the sliding movement along the slide opening 111 of the fixing tool 108 Rotary blade equipped cartridge 100 including a cutter box 101 and is moved to the cutting device width direction.

  In the cutting device having the above-described configuration, the rotary blade 102 is replaced in units of cartridges, and the housing of the cutter box 101 and the guide member 104 serve as a protective wall and surround the blade portion. At this time, the operator can perform the replacement work safely and easily without touching the rotary blade 102.

JP 2003-80491 A

  In the conventional cartridge with a built-in rotating blade as described above, the side edge of the wall covering material after cutting is guided to the outside of the apparatus by the guide member, so that the side edge enters the inside of the apparatus and hinders the driving of the apparatus. It does not occur.

  However, in actual continuous cutting of wall coverings, there is not only side edges but also fine chips scattered around the blade by cutting with a high-speed rotary blade. Most of the debris stays in the cartridge surrounded by the protective wall and does not come out. If the chips accumulate in the housing of the cartridge and accumulate in large quantities as the cutting progresses, there is a risk of hindering the rotation and cutting of the rotary blade.

  Conventionally, the other end of the shaft that pivotally supports the rotary blade is detachably connected to the rotary shaft of the rotary drive means via a joint member. Conventionally, as shown in FIG. The joint member 200 is fixed to the motor 300 via the plate member 201 while being sandwiched between the two plate members 201, and is connected to the rotating shaft 301. The shaft is connected to the joint member 200 from the opposite side. The other end of the shaft is connected, and the shaft and the rotating shaft are connected.

  Therefore, if even a slight deviation occurs in the respective fixed portions of the plate members 201 and the motor 300, these overlap, and the axial alignment in the connected state between the rotating shaft and the shaft via the joint member also causes a deviation, which causes rotation. There is a risk that the rotation of the blade will become unstable, especially when the rotation drive means and the cartridge with built-in rotary blade are provided on both the left and right sides of the wallpaper pasting machine to cut the left and right edges of the wall covering. When such misalignment occurs, the cutting unevenness is large, and it is difficult to adjust the width of the wall covering with high accuracy.

By being obtained simultaneously with proper axis alignment, the cutting width of the wall covering material can be adjusted with high accuracy without uneven cutting when mounting for one-side cutting or mounting for cutting the left and right side edges.

  In the wallpaper cutting apparatus according to the third aspect of the present invention, the rotary blade built-in cartridge that houses the rotary blade and the shaft that pivotally supports the rotary blade is detachably attached to the rotary drive means. The built-in cartridge has a protective wall that surrounds the periphery of the blade of the rotary blade, and an opening is formed in this protective wall, so that the operator can safely and easily rotate the cartridge unit without touching the rotary blade from the outside. The blades can be replaced, and the chips generated when cutting the wall material with high-speed rotation of the rotary blades can be scattered to the outside from the opening of the protective wall, and the chips accumulate in the cartridge and rotate. This has the effect of avoiding the danger of hindering blade rotation and cutting.

  A cartridge with a built-in rotary blade according to a fifth aspect of the present invention houses a rotary blade and a shaft that supports the rotary blade, and is detachably attached to a rotary drive means of a wallpaper cutting device. Since the protective wall is surrounded by a predetermined interval around the blade part and an opening is formed in the protective wall, the operator can safely and easily rotate the rotary blade in cartridge units without touching the rotary blade from the outside. Can be exchanged, and the chips generated when cutting the wall material at high speed rotation of the rotary blade can scatter to the outside from the opening of the protective wall, and the chips accumulate in the cartridge and This has the effect of avoiding the danger of hindering rotation and cutting.

  The present invention described in claim 1 is a wallpaper pasting machine provided with a cutting mechanism for cutting a side edge portion of a wall covering material, and has a rotation driving means for driving a rotary blade for cutting. The shaft that pivotally supports the rotary blade is housed in a cartridge with a built-in rotary blade that can be attached to and detached from the rotation driving means. The cartridge pivotally supports one end of the shaft, and the wall plate It has a protective wall standing upright in a direction substantially parallel to the shaft and surrounding the periphery of the blade of the rotary blade, and an opening is formed in this protective wall.

  Therefore, in the wallpaper pasting machine according to the present invention, the operator can safely and easily replace the rotary blade in units of cartridges without touching the rotary blade surrounded by the wall plate and the protective wall from the outside. Chips generated when cutting wall coverings with high-speed rotation of the rotary blade can scatter from the opening of the protective wall to the outside, so that chips accumulate in the cartridge and adversely affect the rotation and cutting of the rotary blade. Good wall covering cutting work can be maintained without affecting.

  Such an opening may be formed on at least one of the protective walls. However, the larger the proportion of the opening with respect to the protective wall, the greater the effect of preventing chip accumulation. It is preferable to provide openings in all the protective walls. However, if the opening area per opening is large, the operator's finger may enter the cartridge and touch the rotary blade. Therefore, a large number of narrow slit-like openings that are difficult to enter are provided. Configuration is desirable.

  Such an opening can be easily formed by making a slit opening in each wall surface of the protective wall. Further, for example, the opening can be formed by configuring the protective wall with a plurality of columnar members. That is, a space formed between the column members surrounding the rotary blade portion is a slit-like opening. In addition to these slit-shaped openings, various forms can be used as long as the openings can scatter chips from the cartridge outward while safely surrounding the rotary blade. The shape and the number are not particularly limited.

  The cutting mechanism using the cartridge with a built-in rotary blade as described above may be configured to be integrated with the main body of the wallpaper gluing machine, but can be attached to and detached from the main body of the gluing machine as a wall covering material cutting device independent of the main body of the gluing machine. It may be configured to be attached.

  In any case, as a driving means for rotating the rotary blade, the power can be used for cutting as long as the gluing machine main body is driven by an electric motor. It is desirable that a dedicated drive means is provided and the shaft of the rotary blade is connected to the output rotation shaft, and that there is no influence such as a burden on the gluing work by the roll drive on the gluing machine main body side.

  In addition, when the rotary blade built-in cartridge is attached to the rotation drive means, the coupling member is fitted and fixed to the rotation drive means when the rotation shaft of the rotation drive means and the shaft are connected via the joint member, and By using a joint fixing member that has a fitting part that fits and locks the end of the protective wall of the cartridge with a built-in joint rotary blade, it prevents the occurrence of uneven cutting due to mounting misalignment between the rotating shaft and shaft as in the past. can do.

  That is, the joint member is connected to the joint fixing member fixed to the rotation driving means, and the shaft is connected to the shaft so that the joint shaft is determined by the joint fixing member. Since the fixed position is always constant, and the position for receiving the shaft of the joint member is also always constant, the shaft coupling position of the rotating shaft is always constant. Therefore, if the design is such that accurate fitting of the joint member and the rotating shaft can be obtained in a state where the joint member is fitted and fixed to the joint fixing member, the rotating shaft is simultaneously connected to the shaft when the shaft is well connected to the joint member. Completes precise alignment with the shaft.

  Furthermore, the joint fixing member is fitted with the end of the protective wall when the shaft end is connected to the joint member in a precise relative positional relationship for the cutting blade built-in cartridge with respect to the rotational drive means. Therefore, if the shaft is connected to the joint member while fitting and locking the end of each protective column of the cartridge with a built-in rotary blade to the fitting portion, the shaft and the rotation drive means are provided. Accurate alignment with the rotation axis is completed at the same time.

  Therefore, in the present invention, the wall covering material cutting mechanism composed of the rotation driving means and the rotary blade built-in cartridge connected to the rotation driving means ensures a good connection in which the rotation shaft and the shaft are not always displaced in the mechanism, In addition, even when cutting the left and right side edges, there is no axial misalignment between the wall trimming mechanisms installed on both sides, and accurate width adjustment is possible by trimming the wall trim without uneven cutting due to the mounting misalignment of the rotary blade. It can be carried out.

  In addition, the wall covering main body whose width is adjusted by cutting with the rotary blade is drawn into the gluing machine main body inside the rotary blade and glued, but the separated side edges are also inside the gluing machine main body. There is a danger if it is pulled in. Therefore, in the cartridge with a built-in rotary blade of the present invention, it is preferable to attach a guide plate that leads the side edge portion separated by the housing to the outside of the gluing machine main body different from the conveyance path of the wall covering material main body. There is no possibility that the side edge part cut off by the lead-out of the gluing machine main body by this guide plate will enter the gluing machine main body and hinder driving or cause damage.

  In this case, the guide plate may constitute one wall surface of the cartridge housing as a protective wall by attaching the guide plate. For example, if the cartridge housing is formed in a substantially U-shaped casing shape by the protective wall and the outside (rear side) is an open surface with respect to the gluing machine body, the cartridge housing can be attached to cover the open surface In addition, the side edge of the wall covering material that is cut off can be led out to the outside of the apparatus while being a protective wall that covers the periphery of the rotary blade. At this time, the guide plate is attached to the cartridge housing without interfering with the path through which the wall covering material to be cut passes through the rotary blade portion.

  Hereinafter, as an embodiment of the present invention, a wallpaper cutting apparatus in which a rotary blade built-in cartridge is detachably mounted on a rotation drive means dedicated to cutting will be described with reference to FIGS. FIG. 1 is a schematic configuration diagram showing, in perspective from the apparatus mounting side, a connecting portion between a small motor serving as a rotation driving means constituting a cutting mechanism before being incorporated into the cutting apparatus and a cartridge incorporating a rotary blade ( a) shows the assembled and connected state of each member, and (b) shows the disassembled state of each member. FIG. 2 is a schematic configuration diagram of the housing of the cartridge with a built-in rotary blade, wherein (a) is a front view of the housing, (b) is a left side view of the housing, and (c) is a plan view of the housing as viewed from above. FIG. 3 is a schematic configuration diagram of the joint fixing member, where (a) is a front view of the member, and (b) is a right side view.

  In this cutting apparatus, the small motor 30 is attached to the slide bracket 40 slidably mounted in the body width direction of the cutting apparatus that matches the wall covering material width direction along the guide stay formed in the housing of the cutting apparatus body. It is housed and fixed in the fixed motor bracket 41. Therefore, by connecting the cartridge 1 with a built-in rotary blade to the small motor 30, the motor bracket 41 and the motor 30 can be slid together in the apparatus width direction, and the rotation stored in the cartridge 1 by adjusting the sliding movement amount. The cutting position of the blade 10 can be adjusted.

  As shown in FIGS. 1 and 2, the housing 2 of the cartridge 1 with a built-in rotary blade in the present embodiment is a three-surface protective wall that covers the periphery of the rotary blade other than the wall material contact side in a substantially U-shaped side section. (5a, 5b, 5c) and the side wall plate 3 on which the pivotal support portion 4 that pivotally supports one end of the shaft 11 that pivotally supports the rotary blade 10 via the boss B is formed into a substantially casing shape. It is a thing. Of these protective walls, the two protective walls (5a, 5b) that are exposed to the outside when mounted on the cutting device have a plurality of slit-shaped openings S each having a width that does not allow a finger to enter. It is drilled over almost all wall surfaces.

  Furthermore, the side edge part cut | disconnected from the wall covering body main body after a cutting | disconnection is formed in the cutting surface formed in the open surface of the said substantially U-shaped side cross section located in the outer surface opposite to the cutting device mounting side of the housing 2 apparatus. It is assumed that a guide plate 9 for leading out is attached.

  As described above, the cartridge 1 with the built-in rotary blade, which is configured by attaching the guide plate 9 to the outside of the housing 2 in which the rotary blade 10 and the shaft 11 are housed, is detachable from the small motor 30 in units of the cartridge 1. Connection and replacement work is performed.

  Therefore, in the cartridge 1 with a built-in rotary blade, the rotary blade 10 is surrounded by the side wall plate 3, the protective walls (5a, 5b, 5c) and the guide plate 9, so that the operator does not touch the rotary blade 10 from the outside. The rotary blade 10 can be replaced safely and easily in cartridge units, and chips generated when cutting the wall covering material at a high speed of the rotary blade 10 are formed on the protective walls (5a, 5b). Since it is possible to scatter from the opening S to the outside, good wall covering material cutting operation can be continued without causing chips to accumulate in the cartridge and adversely affecting the rotation of the rotary blade 10 and the wall covering material cutting.

  Further, the side edge portion separated from the wall covering main body by cutting by the guide plate 9 is separated from the path of the wall covering main body to be drawn into the gluing machine main body to which the cutting device is attached. Therefore, there is no danger that the side edge portion is drawn into the gluing machine and hinders the drive of the gluing machine or causes damage.

  In addition, the connection of the cartridge 1 with the rotary blade to the motor 30 in the present embodiment is made through the joint member 12 that connects the other end of the shaft 11 and the output rotation shaft 31 of the motor 30. The joint member 12 connects the rotary shaft 31 and the shaft 11 in a state where the joint member 12 is fitted and fixed to the joint fixing member 20 fixed to the motor bracket 41 and the motor 30. That is, the position where the joint member 12 is fixed to the motor 30 and the rotary shaft 31 determined by the joint fixing member 20 is always constant, and the position where the shaft 11 of the joint member 12 is received is always constant. The connection position with the shaft 11 is always constant.

  Further, as shown in FIGS. 1 and 2, the shaft 11 is connected to the joint member 12 without any axial displacement in the relative position because the cartridge 1 with a built-in rotary blade is preliminarily cut with respect to the motor 30. In this state, the end of the protective wall (5a, 5b, 5c) is fitted and locked at a predetermined position in a region where the end of the protective wall (5a, 5b, 5c) of the cartridge 1 with built-in rotary blade contacts. Fitting portions (22a, 22b, 22c) are provided.

  In this embodiment, as shown in FIG. 1B, recesses (5x, 5y, 5z) are formed at predetermined positions on the end portions of the protective walls (5a, 5b, 5c), and the joint fixing member 20 corresponds. The fitting parts (22a, 22b, 22c) which consist of the convex part fitted to these recessed parts (5x, 5y, 5z) were formed in the position. Therefore, if the shaft 11 is connected to the joint member 12 while fitting the fitting portions (22a, 22b, 22c) corresponding to the concave portions (5x, 5y, 5z), the rotating shaft 31 and the shaft are simultaneously connected. Accurate alignment with 11 is also completed.

  In addition, as a fitting locking mechanism of the fitting part (22a, 22b, 22c) with respect to the edge part of each protective wall (5a, 5b, 5c), the end of the above protective walls (5a, 5b, 5c) Convex portions (22a, 22b, 22c) that fit into the concave portions (5x, 5y, 5z) partially formed in the respective portions, or a configuration in which the concave and convex portions of both are reversed, are simple, For example, any mechanism that can be detachably fitted and locked, such as forming a groove portion into which the end portion of the protective wall itself is fitted as it is, in a corresponding region of the joint fixing member 20 can be widely used.

  As described above, the joint fixing member 20 always fits and locks the ends of the protective walls (5a, 5b, 5c) with the fitting portions (22a, 22b, 22c), and at the same time, the fitting fixing member 20 is fitted. Since the coupling state of the rotary shaft 31 and the shaft 11 can be obtained simultaneously with the accurate axial alignment of the rotary shaft 31 and the shaft 11 through the joint member 12 fitted and fixed to the portion 21, in this cutting apparatus, the rotational drive Axis displacement in the wall covering material cutting mechanism in which the means and the cartridge with the built-in rotary blade are connected is also performed when the wall covering material cutting mechanism is incorporated on each of the left and right sides of the cutting device for cutting the left and right side edges. Since the axial displacement between the mechanisms is also avoided, it is possible to adjust the cutting width of the wall covering material with high accuracy without causing uneven cutting due to the mounting displacement of the rotary blade 10.

  The rotary blade built-in cartridge 1 connected to the motor bracket 41 and the motor 30 via the joint fixing member 20 and the joint member 12 moves along with the slide of the slide bracket 40 together with the motor bracket 41 and the motor 30, and is in a cutting position. Can be adjusted. As a specific position adjusting mechanism, for example, a slit opening is provided in the guide stay of the cutting apparatus main body along the width direction of the main body, and a tightening screw provided with an operation knob is connected to the slide bracket 40 through the slit opening. When the tightening screw is tightened against the guide stay, the motor bracket 41 and the motor 30 are fixed to the guide stay together with the slide bracket 40, and the operation knob is accompanied by the slide bracket 40 in a state where the tightening screw is loosened by the rotation of the operation knob. A configuration that can be slid and moved is simple.

  In addition, the support of these cutting mechanisms is not dependent only on the slide bracket, but a structure that supports from the side of the cartridge 1 with a built-in rotary blade is desirable from the viewpoint of overall movement and fixing stability. In the present embodiment, in order to support from the cartridge 1 side with the built-in rotary blade, instead of the fixing bracket 105 which is conventionally fixed by screwing to the cutter box 101, the fixing is integrally formed outside the side wall plate 3 of the housing 2. A bracket portion 6 was provided.

  The mechanism for moving and fixing the rotary blade built-in cartridge 1 via the fixing bracket portion 6 is the same as in the prior art, in which the tightening screw 8 provided with the operation knob 7 is positioned in the apparatus width direction at the corresponding position of the guide stay of the cutting apparatus body. The fixing bracket portion 6 is connected to the fixing tool when the tightening screw 8 is advanced by the rotation of the operation knob 7. Then, the guide stay is pressed and clamped to obtain a tightened and fixed state with respect to the guide stay. When the operation knob 7 is rotated and the screwing of the tightening screw 8 with respect to the fixture is loosened, the fixed state of the fixing bracket portion 6 is released. The cartridge 1 with the built-in rotary blade including the fixed bracket portion 6 is moved in the width direction of the cutting device.

  In the case where the fixing bracket is fixed to the cutter box with a separate member as in the prior art, if the fixing is misaligned, the mounting misalignment from the fixing bracket portion 6 of the housing 2 is pivoted to the side wall plate 3 of the shaft 11. There is a possibility that the accurate alignment state with the rotating shaft 31 of the shaft 11 obtained as described above may not be maintained because of acting on the supported side. By integrally forming the housing 2, the risk of mounting misalignment that occurs when another member is screwed and fixed is avoided, and an accurate alignment state of the shaft 11 with the rotating shaft 31 can be satisfactorily maintained.

  In the above embodiment, the case where the slit-like opening formed in the predetermined wall surface is provided as the opening formed in the protective wall is shown, but the present invention is not limited to this, for example, By forming the protective wall with a plurality of columnar members, a space formed between these columnar members may function as an opening. In this case, the joint fixing member may be formed with a fitting portion for fitting and locking the end portion of each columnar member.
