DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper sizing machine for continuously applying glue to the back of a long wall material when, for example, attaching a sheet-like wall material to an indoor wall surface. More particularly, the present invention relates to a glue amount adjusting means for adjusting the amount of glue adhered to a glue roll.

[0002]

2. Description of the Related Art A sheet-like wall covering material drawn from a rear surface of a main body is moved along a predetermined path in the main body by a plurality of rolls, and is continuously applied to the back surface of the wall covering material by a gluing roll. In the sizing machine, the amount of glue applied to the wall covering varies depending on the type of wall covering used, the type or state of the paste, and other working environments. It is necessary to set the optimal one.
For this reason, in the conventional wallpaper sizing machine, the doctor roll is arranged close to the sizing roll, and the amount of the glue adhered to the sizing roll is adjusted by adjusting the relative distance between the doctor roll and the sizing roll. I have. Here, FIGS. 5 and 6 show schematic configuration diagrams of a mechanism for adjusting the amount of glue adhered in a conventional wallpaper gluing machine.

The wallpaper gluing machine shown in FIG. 5 includes a doctor roll 507 eccentrically supported on a shaft, a fan-shaped gear 505 mounted on both shaft ends of the doctor roll 507 and rotatable around the shaft ends. Second gear 51 meshing with the sector gear 505
1 and a dial 512 for rotating the second gear 511
And a stopper 510 for inhibiting rotation of the dial 512 from a desired rotation position. On the surface of the dial 512, a scale indicating the relative distance movement amount with respect to the gluing roll 508 is displayed. In this wallpaper gluing machine, when the operator rotates the dial 512 to a desired position, the doctor roll 507 rotates via the second gear 511 and the sector gear 505, and the relative position between the gluing roll and 508 is increased. The interval is adjusted, so that the amount of glue adhering to the gluing roll 508 is adjusted.

[0006] The wallpaper gluing machine shown in FIG. 6 has a sector gear 605 rotatable around the top and a sector gear 605 at one end.
A lever 613 attached to the side of the gluing machine main body by a bolt 610;
A scale plate 611 provided on the side of the handle 616. The lever 613 is rotatable up and down around a bolt 610 as a fulcrum. Holes are drilled at predetermined intervals on the scale plate 611, and the fixing screw 612 is tightened to the hole at a desired scale position, thereby making the lever 613.
Is fixed to the scale plate to inhibit the rotation of the lever. In addition, the doctor roll 607 includes the sector gear 60.
Doctor roll 6 at a position eccentric from the center of rotation of 5
07 is held by a sector gear 605 so as to be relatively rotatable. In this wallpaper gluing machine, when the handle portion 616 is rotated in the vertical direction, the tooth profile portion 615 is rotated in the opposite direction to the handle portion 616, and accordingly, the sector gear 605 is moved to the front side of the gluing machine body or It turns to the rear side. As a result, the shaft end of the doctor roll 607 held by the sector gear 605 is relatively moved with respect to the gluing roll 608, and the relative distance between the doctor roll 607 and the gluing roll 608 changes, and the amount of glue adhering to the gluing roll 608 is reduced. It can be adjusted.

[0005]

However, such a wallpaper sizing machine has the following problems. In the wallpaper gluing machine shown in FIG. 5, since the amount of glue is adjusted by the operator turning the dial to a desired position, accurate positioning is difficult depending on the force of the operator. Cannot rotate to position. For this reason, there is a problem that the amount of glue adhering to the gluing roll cannot be adjusted accurately. Also, it may take time to accurately adjust the dial to the desired scale position.

In the wallpaper gluing machine shown in FIG. 5, dials 512 each indicating a scale are provided on both sides of the gluing machine main body. From the side to the side. In particular, the scale displayed on the dial side cannot be seen from the front of the main unit, so the operator must move from the front to the side of the main unit every time the glue amount is adjusted, making the operation extremely complicated. There is a problem that becomes.

On the other hand, in the case of the wallpaper sizing machine shown in FIG. 6, the handle and the scale are provided on the front of the sizing machine main body. Excellent in that you don't have to go to. However, as shown in FIG. 6, since the scale plate is provided so as to protrude outward in front of the main body of the gluing machine, there is a case where it becomes an obstacle for a worker on the front side, and workability is poor. In addition, in order to fix the rotated lever at a desired scale position, the operator needs to tighten the handle to the scale plate with a fixing screw, which complicates the work, and also requires adjustment of the amount of glue. There is a problem that it takes time.

The present invention has been made in view of the above problems, and has as its main object to provide a wallpaper gluing machine capable of accurately adjusting the amount of glue with a simple operation. Another object of the present invention is to provide a wallpaper sizing machine capable of improving the operability of the entire sizing operation by avoiding the complexity of the operation of adjusting the amount of glue. Another object of the present invention is to provide a wallpaper sizing machine that can reduce the time required for the operation of adjusting the amount of glue.

[0009]

In order to achieve the above-mentioned object, the invention according to the first aspect is directed to a sheet-like wall covering material pulled in from a rear surface portion of a sizing machine main body by the plurality of rolls. A wallpaper sizing machine that moves the inside of the unit along a predetermined path and continuously applies the back surface of the wall covering material by the sizing roll, wherein the sizing roll and the sizing roll are disposed in proximity to the inside of the main body. A plurality of rolls including a doctor roll, and a glue amount adjusting unit that adjusts a glue amount attached to the glue roll by adjusting a relative distance between the doctor roll and the glue roll. The adjusting means adjusts the amount of gluing by rotating a forward / reverse rotatable adjusting gear attached to the shaft end of the doctor roll. With stepwise forward and reverse rotation by the number units, it is characterized in that and a gear rotating means capable of maintaining the rotation state.

According to the first aspect of the present invention, the adjusting gear is rotated forward and backward stepwise by a fractional unit of the gear by the gear rotating means to maintain the rotating state. , So the relative distance between the doctor roll and the glue roll is also changed step by step,
Maintain the changed state. That is, since the adjusting gear rotates stepwise and maintains the rotation, the operator only has to repeat the stepwise rotation of the adjusting gear by the gear rotating means until the relative interval becomes a desired interval. It is possible to change the interval between the doctor roll and the sizing roll to a desired interval regardless of the force applied. Thus, according to the present invention,
Accurate adjustment of the amount of glue adhering to the gluing roll can be performed by a simple operation by the gear rotating means. Also,
As described above, according to the present invention, it is possible to accurately and accurately adjust the amount of glue by a simple operation of repeating the stepwise operation by the gear rotating means. This can be performed in a shorter time than in a machine.

The configuration of the gear rotating means in the present invention is limited as long as it can rotate the adjusting gear forward and backward stepwise in increments of the gear and can maintain the rotating state. Not something. For example, as the gear rotating means, a movable member as an operation unit for pushing the pawl gear and the teeth in fractions can be used. Also,
In addition to configuring the gear rotating means to directly push the teeth of the gear mounted on the doctor roll shaft end, a gear transmission comprising a plurality of gears between the gear mounted on the doctor roll shaft end and the gear rotating means By providing a mechanism and pushing the gear teeth of the gear transmission mechanism, the gear teeth mounted on the doctor roll shaft end can be pushed indirectly and rotated stepwise. In this case, there is an advantage that the relative spacing between the doctor roll and the gluing roll can be further finely adjusted by returning the gear ratio of the gear at the doctor roll shaft end and each gear of the gear transmission mechanism.

Further, as the gear rotating means of the present invention, a means for pushing the teeth in the direction of rotating the gear in the forward direction and a means for pushing the teeth in the direction of rotating the gear in the reverse direction are provided separately. The gear rotation means may be configured to switch between normal rotation and reverse rotation of the gear so as to push the teeth. Here, when the gear rotates forward, the relative distance between the doctor roll and the gluing roll increases, and when the gear rotates reversely, the relative distance between the doctor roll and the gluing roll decreases, or vice versa. It is optional.

The gear rotating means in the present invention may be any gluing amount adjusting means for adjusting the amount of glue adhered to the gluing roll by adjusting the relative distance between the doctor roll and the gluing roll by rotating the gear. It is also possible to apply to adjusting means. For example, the doctor roll is supported at a position eccentric from its axis, and the doctor roll is rotated by a gear to adjust the relative distance between the doctor roll and the gluing roll, or eccentric from the rotation center of the gear. Any of the gluing amount adjusting means, etc., which adjusts the relative distance between the doctor roll and the gluing roll by attaching the shaft end of the doctor roll to the set position and rotating the gear to change the supporting position of the doctor roll. Can also be applied.

The present invention can be applied to both a manual wallpaper sizing machine for manually transferring wall coverings and an automatic wallpaper sizing machine for transferring wall coverings by driving an electric motor. It is.

According to a second aspect of the present invention, in the wallpaper pasting machine according to the first aspect, the gear rotating means pushes teeth of the adjustment gear to rotate the adjustment gear, The present invention is characterized in that it comprises a stop claw portion engaging with the teeth against the rotation of the adjustment gear, and an operation portion pressing the feed claw portion.

According to the second aspect of the present invention, the teeth of the adjusting gear are pushed by the feed pawl to rotate the adjusting gear. At this time, the stopper pawl faces the teeth of the adjusting gear against the rotation of the adjusting gear. Is engaged. Therefore, the rotation of the adjusting gear is prevented by the stopper claw when the adjusting gear is rotated in fractions of teeth. That is, the adjusting gear is surely rotated stepwise in units of a fraction of the gear, and the adjusting gear is prevented from rotating more than necessary, so that it is possible to perform a reliable and accurate adhesive thickness adjustment.

The feed pawls in the present invention include those that rotate the adjustment gear in one direction, and those that use two pairs of feed pawls to rotate the adjustment gear in both directions. Further, it is sufficient that the pawl portion engages with the teeth against the rotation of the adjustment gear, and the position of engagement with the teeth of the adjustment gear can be arbitrarily determined. When the feed claw is configured to rotate the adjustment gear in both directions, two stop claws are provided to oppose each rotation direction, and one stop claw is used to rotate the adjustment gear more than necessary. It may be configured so as to prevent the adjustment gear from rotating more than necessary by the other pawl.

In a preferred aspect of the gear rotating means, the gear rotating means pushes teeth of the adjusting gear to rotate the adjusting gear in opposite directions, and a pair of feed claws; One that includes an operation unit that presses each of the pair of feed claws independently of each other, and a stopper claw that prevents rotation in both forward and reverse directions when the adjustment gear rotates in fractional units. .

Since the doctor roll is close to the gluing roll, a rotating force is applied to the doctor roll while the wall covering material is being conveyed, and the adjusting gear also tries to rotate in a direction corresponding to the rotation direction of the doctor roll. On the other hand, in the present invention, the pair of feed claws rotate the adjustment gear in opposite directions, but when the operation gear presses one of the feed claws and the adjustment gear is rotated in fractions, the rotation is performed. The direction may be opposite to the direction in which the rotational force from the doctor roll acts. At this time, when the stopper claw that restricts rotation in only one direction is used, rotation from the doctor roll may not be prevented in some cases. However, in the invention of this aspect, when the pawl portion rotates the adjusting gear in fractional units,
Since the rotation in both the forward and reverse directions is prevented, the adjustment gear is prevented from rotating in both the forward and reverse directions against the rotational force from the doctor roll. Therefore, unnecessary rotation of the adjustment gear can be prevented from occurring with rotation of the doctor roll, and the amount of gluing can be reliably adjusted.

According to a third aspect of the present invention, in the wallpaper gluing machine according to the first aspect, a stepwise rotation amount of the gear by the gear rotating means or an adjustment state of the amount of glue according to the rotation position of the gear is displayed. And a display unit of the display unit is provided at a front portion of the gluing machine main body.

In the invention according to the third aspect, the display means displays the stepwise rotation amount of the gear or the adjustment state of the amount of glue according to the rotation position of the gear, so that the operator can operate the gear rotation means. The glue amount can be adjusted while always checking the operation result during the operation, and the glue amount can be surely adjusted.

Further, in the present invention, since the display section of the display means is provided at the front of the gluing machine main body, the worker who is performing the gluing operation confirms the adjustment of the glue amount while being positioned at the front of the gluing machine main body. It can be carried out. For this reason, compared with the conventional wallpaper gluing machine which has to be moved to the side of the main body every time the glue adjusting operation is performed, the complexity of the operation can be avoided and the workability of the entire gluing operation can be improved. it can. In this case, if the operation unit of the gear rotating means is further provided at the front of the gluing machine main body, the operability is improved, which leads to a further improvement in the workability of the entire gluing operation.

The configuration of the display means in the present invention is not limited as long as it displays the stepwise rotation amount of the gear by the gear rotation means or the adjustment state of the amount of glue according to the rotation position of the gear. For example, in addition to the configuration in which the count number is increased or decreased by one in accordance with the rotation of one tooth of the adjustment gear, the count number is increased or decreased and displayed in response to the rotation of a fixed number of teeth. It is optional to configure so that In the former case, there is an advantage that the structure of the display means is simplified.

On the front side inside the lower structure 2, there is provided a counter unit 34 constituting the glue amount adjusting means of the present invention.

On the other hand, in the upper structure 3, an upper pinch roll 10 which forms a pinch roll in combination with the delivery roll 6 and has a measuring function, and rolls and gears arranged in the lower structure 2. A drive roll 12 for applying a feeding tension toward the front of the gluing machine main body to the cloth C, and a pressing stay for pressing the cloth C from above between the upper pinch roll 10 and the drive roll 12 11 are supported by bearing frames on both sides of the main body of the upper structure 3 so as to be arranged in parallel at a predetermined interval.

In the gluing machine main body 1 of the present embodiment, the delivery roll 6 of the lower structure 2 is pivotally supported via a hinge 5 which is detachably and rotatably supported by the glue tub 4. It is connected to the rotating shaft of an electric motor (not shown) as a drive source, and transmits the rotating motion of the electric motor to another roll interlocked via a gear.

Further, in the gluing machine main body 1 of the present embodiment, a groove is provided on the rear surface side of the lower structure 2 in the width direction of the apparatus, and a slitter 20 is attached to an under stay 26 in the groove. By moving the slitter 20 in the width direction in the groove 34, the width of the ear P is adjusted. And the cross passage part of the slitter 20 is just the lower structure 2
Is formed along the rear side wall surface. In this slitter 20, one (one-sided) rotary blade and a shaft that supports the rotary blade are built in a rotary blade built-in cartridge 22.

The doctor roll 7 adjusts the amount of glue adhering from the glue tub 4 to the glue roll 8 by adjusting the relative distance (gap) between the doctor roll 7 and the glue roll 8, and is thereby applied to the cloth. The glue amount is adjusted.

FIG. 2 is an enlarged view showing the configuration of the glue amount adjusting mechanism in the present embodiment. Doctor roll 7
It is supported by a bearing plate at a position eccentric from its center,
A fan gear 35 is mounted on the shaft end. This sector gear 35 constitutes the adjusting gear of the present invention. Sector gear 35
Is rotatable forward and backward about the shaft end, and when the sector gear 35 rotates, the doctor roll 7 also rotates. At this time, since the doctor roll 7 is eccentrically supported by the shaft, the relative distance (gap) between the outer peripheral surface of the doctor roll 7 and the outer peripheral surface of the gluing roll 8 changes as the doctor roll 7 rotates.

Between the sector gear 35 and the counter unit 34, a first gear 38 and a second gear 39 are provided. The sector gear 35 and the first gear 38, and the first gear 38 and the The second gear 39, the second gear 39, and the third gear 40 in the counter unit 34 are meshed with each other.

The third gear is constituted by a pawl gear.
The counter unit 34 rotates the third gear 40 in a stepwise manner, rotates the sector gear 35 through the second gear 39 and the first gear 38 in a stepwise manner, and maintains the state. The relative distance between the roll 7 and the gluing roll 8 is changed stepwise to adjust the amount of glue adhering to the gluing roll 8. The counter unit 34, the first gear 38, the second gear 39, and the sector gear 35 constitute the glue amount adjusting means of the present invention. FIG. 3A is an enlarged side view illustrating a schematic configuration of the counter unit 34, and FIG.
3 is an enlarged front view of the counter unit 34. FIG. FIG.
As shown in (a) and (b), the counter unit 34
3 includes a third gear 40 rotatably supported in forward and reverse directions, and two movable members 36a and 36b which are horizontally inserted from the front side of the counter unit 34 and are capable of reciprocating in the left-right direction of FIG.
Is provided. In addition, a counter display unit 43 that displays the rotation amount of the third gear 40 is provided at the center of the front of the counter unit 34. First gear 38, second gear
Gear 39 and the third gear 4 of the counter unit 34
The zero and two movable members 36a and 36b constitute gear rotating means of the present invention, and the counter display section 43 constitutes display means of the present invention. The two movable members 36a and 36b constitute an operation section of the gear rotating means of the present invention.

The third gear 40 is formed with a first tooth profile 41 and a second tooth profile 42 having different outer diameters concentrically, and the first tooth profile 41 meshes with the second gear 39. ing.

The ends of the movable members 36a, 36b slightly protrude from the front frame of the counter unit 34, so that the movable members 36a, 36b are viewed from the front side of the counter.
b can be pushed in. By the pushing operation of the upper movable member 36a, the movable member 36a pushes the tooth surface of the upper tooth of the second tooth profile 42 to push the tooth, and the rotation of the tooth is regulated by the claw 37a. Further, the movable member 3 is pushed by the lower movable member 36b.
6b presses the tooth surface of the lower tooth of the second tooth profile portion 42 to push the tooth, and the rotation of the tooth is regulated by the claw portion 37b.
Therefore, the third gear can be rotated forward and backward in units of fractions of the second tooth profile 42.

The movable members 36a and 36b are urged toward the front frame of the counter unit 34.
Therefore, when the pushing is released, the movable member 36a,
36b returns to the home position shown in FIG.

The counter display section 43 displays the amount of rotation of the third gear 40.
5 can be grasped. A numerical value indicating the amount of rotation of the third gear is displayed on the counter display unit 43, and the numerical value increases or decreases in accordance with the number of presses of the movable members 36a and 36b (the number of teeth moved by the third gear 40). It is supposed to. That is, the numerical value is incremented by 1 by pressing the upper movable member 36a once, and the numerical value is decremented by 1 by pressing the lower movable member 36b once. Therefore, the operator can read the counter display section 43
By confirming the numerical value of (1), the relative distance between the doctor roll 7 and the gluing roll 8 can be grasped.

In the sizing machine main body 1 configured as described above, when adjusting the amount of sizing, the operator moves the upper movable member 36a or the lower movable member 3 from the front side of the sizing machine main body 1.
The pushing operation of 6b is performed as follows.

In order to increase the relative distance between the doctor roll 7 and the gluing roll 8, the upper movable member 36a is pushed. At this time, the movable member 36a presses the tooth surface of the tooth located above the third gear 40 to push the tooth, and further the rotation is regulated by the claw 37a, so that the third gear 40 is a fraction of the tooth. Only in the direction A, the state is maintained. This rotation is performed by the second gear 39 and the first gear 38.
Is transmitted to the sector gear 35 through the shaft and pushes the teeth of the sector gear 35, and as a result, the sector gear 35 rotates in the direction a. As a result, the doctor roll 7 also rotates in the direction a. However, since the doctor roll 7 is eccentrically supported by the shaft, the rotation of the doctor roll 7 increases the relative distance between the doctor roll 7 and the gluing roll 8. Accordingly, the numerical value of the counter display unit 43 becomes 1
Is only incremented.

On the other hand, a doctor roll 7 and a gluing roll 8
In order to narrow the relative distance between the two, the lower movable member 36b is pushed. At this time, the movable member 36b is connected to the third gear 4
Press the tooth surface of the tooth located at the bottom of 0 to push the tooth forward,
Further, the rotation is restricted by the claw portion 37b. For this reason, the third gear 40 rotates in the direction B by the fraction of the teeth, and the state is maintained. The third gear 40 pushes the teeth of the sector gear 35 through the second gear 39 and the first gear 38, and as a result, The sector gear 35 rotates in the direction b. This makes doctor roll 7
Also rotates in the direction b, and the relative distance from the gluing roll 8 is reduced. Accordingly, the numerical value of the counter display section 43 is decremented by one.

As described above, the relative distance between the doctor roll 7 and the gluing roll 8 is adjusted stepwise by the movable members 36a and 36b.

The pushing operation of the upper movable member 36a or the lower movable member 36b is repeated while checking the numerical value of the counter display section 43 until the relative distance between the doctor roll 7 and the gluing roll 8 becomes a desired distance.

As described above, in the automatic wallpaper sizing machine of this embodiment, the adjustment of the amount of sizing to the sizing roll 8 is performed stepwise by a simple operation of repeatedly pressing the movable members 36a and 36b of the counter unit 34. Therefore, the amount of glue can be accurately adjusted without being affected by the force of the operator, and the work time for adjusting the amount of glue can be shortened.

On the front (front) of the gluing machine main body 1,
Since only the ends of the movable members 36a and 36b of the counter unit 34 protrude, there is no hindrance to the work of each part of the counter unit 34 for the worker standing on the front side.

After the operation of adjusting the amount of glue, the upper structure 3 is rotated with respect to the lower structure 2 to be in an open state, and the cloth C fed from the raw roll is passed through the slitter 20 onto the lower structure 2. When the upper structure 3 is closed after the tip is placed in a state of being hung in front of the main body, the cloth C is sandwiched between predetermined rolls of the lower structure 2 and the upper structure 3 as shown in FIG.

When the electric motor is driven in this state of holding the cloth, the rotation of the delivery roll 6 starts, and at the same time, the other rolls connected to the delivery roll 6 via gears start interlocking rotation. On the other hand, a slitter electric motor provided separately from the motor of the gluing machine main body is driven to rotate the rotary blade 23 of the slitter 20.

As a result, each roll connected by the gear rotates at a predetermined peripheral speed ratio, and the glue tub 4 attached to the gluing roll 8 is rotated.
The paste inside is adjusted to a desired paste amount by the doctor roll 7 whose relative distance to the paste roll 8 is changed by the operation of the counter unit 34, and the paste roll 8 is attached to the back surface of the cloth that moves with the rotation of the paste roll 8. The surface glue is applied.

If the amount of glue applied to the cloth is not appropriate, the electric motor is stopped, and the relative spacing between the doctor roll 7 and the glue roll 8 is adjusted again by pushing the operating member described above. . In this case, since the counter unit 34 is mounted on the front side of the gluing machine main body 1, the operator can adjust the amount of glue while being positioned on the front side of the gluing machine main body. Work efficiency is improved without the need to move.

In the wallpaper gluing machine according to the present embodiment, the counter unit 34 gives the doctor roll 7 and the glue roll 8 a stepwise rotation to the sector gear 35 on which the eccentrically supported doctor roll 7 is mounted. In addition to the above, a configuration in which the relative interval is adjusted by gradually rotating a sector gear 35 mounted at a position where the shaft end of the doctor roll is eccentric from the center of rotation is adjusted. The counter unit 34 may be applied.

Further, in the wallpaper gluing machine of this embodiment, the movable members 36a and 36b rotate the third gear 40 in the counter unit 34 in a stepwise manner, and the rotation is controlled by the second gear 39 and the first gear 39. However, the third gear 40 may directly rotate the sector gear 35 in a stepwise manner.

(Second Embodiment) Next, a wallpaper gluing machine according to a second embodiment will be described. In the wallpaper gluing machine of the second embodiment, a third gear as a glue thickness adjusting mechanism and a rotation mechanism of the third gear are different from those of the first embodiment.
The description is omitted because it is similar to the embodiment. FIG. 4 shows the second
FIG. 2 is an enlarged side perspective view showing a configuration of a glue amount adjusting mechanism in the automatic wallpaper gluing machine of the embodiment.

Also in this embodiment, the rotation of the third gear 40 for adjusting the adhesive thickness is constituted by a pawl gear mechanism.

I have. The push buttons 44a and 44b protrude from the front side of the gluing machine main body 1 so that an operator can easily operate from the front side of the gluing machine main body. Here, the first gear 38, the second gear 39, and the third gear 4
The zero and two feed claws 46a and 46b, the detent pawl 47, and the push buttons 44a and 44b constitute gear rotating means of the present invention.

As shown in FIG. 4, the third gear 40 has a first tooth profile 4 having a different outer diameter concentrically as in the first embodiment.
1 and a second tooth profile 42 are formed, and the first tooth profile 4
1 meshes with the second gear 39.

One end (the right end in FIG. 4) of each of the feed claws 46a, 46b is in contact with the push button 44a, 44b, respectively, and the projecting portion 49 of each of the feed claws 46a, 46b.
Reference numerals a and 49b press the teeth of the second tooth profile portion 42 of the third gear 40. Push buttons 44a, 44b
Is rotatably supported by a support shaft 45, and presses the upper feed claw portion 46a by rotating the upper push button 44a in the A direction to push the teeth of the second tooth profile portion 42. To rotate the gear 40 in the direction a. At this time, the lower feed claw 4
FIG. 4B shows the rotation of the third gear (second tooth portion 42) in FIG.
, And the lower push button 44b rotates in the A direction accordingly.

On the other hand, by rotating the lower push button 44b in the direction B, the lower feed claw portion 46b is pressed to push the second tooth portion 42 to rotate the gear 40 in the direction b. At this time, the upper feed claw portion 46a is pressed rightward in FIG. 4 by the rotation of the third gear (the second tooth profile portion 42), and the upper push button 44a rotates in the B direction accordingly. As described above, the third gear 40 can be rotated forward and backward by rotating the push buttons 44a and 44b.

The pawl portion 47 is provided so as to sandwich the second tooth portion 42 of the third gear 40, and the pawl portion 4 is provided.
The upper bent portion 48a of 7 is engaged with the upper teeth of the second tooth profile, and the lower bent portion 48b is engaged with the lower teeth of the second tooth profile. For this reason, when the third gear 40 is rotated by the rotation of the push buttons 44a and 44b and the teeth of the second tooth profile 42 are pushed forward, the engagement state of the pawls 47 with the teeth is temporarily released. Are bent portions 48a, 48 of the pawl portion 47.
b engages with the next pushed tooth to prevent rotation of the third gear 40 (second tooth profile 42). Therefore, the third gear 40
Rotates forward and backward in units of the number of teeth of the second tooth profile 42.

At this time, with the rotation of the doctor roll 7 due to the transport of the cloth, a rotational force in the direction b acts on the second tooth profile portion 42.
8a is engaged with the upper tooth of the second tooth profile, and the lower bent portion 48b is engaged with the lower tooth of the second tooth profile, so that the second tooth profile 42 opposes the rotational force from the doctor roll 7. Is also restricted from rotating in the b direction in addition to the a direction. For this reason, unnecessary rotation of the second tooth profile 42 is prevented from occurring with the rotation of the doctor roll 7, and the amount of gluing can be reliably adjusted.

As described above, in the wallpaper sizing machine of the present embodiment,
When the teeth of the second tooth profile 42 of the third gear 3 are pushed and rotated by the feed claws 46a and 46b, the stopper claws 4
7, when the third gear rotates by the number of teeth of the second tooth profile 42, the rotation in both the forward and reverse directions is prevented. For this reason, the third gear 40 is surely rotated stepwise in units of the number of teeth of the gear, and the third gear 40 is prevented from rotating more than necessary, so that a reliable and accurate adhesive thickness adjustment is performed. It becomes possible.

In each of the wallpaper sizing machines of the first and second embodiments described above, the mechanism for adjusting the paste thickness at one shaft end of the doctor roll has been described. An adjustment mechanism is provided. And in this embodiment, in order to make the adhesive thickness of the cloth uniform,
The glue thickness adjusting mechanisms at each shaft end can push the rotation of the third gear 40 independently and independently. The glue thickness adjusting mechanisms at both shaft ends may be operated in conjunction with each other.

In the first embodiment and the second embodiment,
Although the present invention is applied to an automatic wallpaper sizing machine, the present invention can also be applied to a manual wallpaper sizing machine in which cloth is transported manually.
