Description

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. In particular, the present invention relates to a wallpaper sizing machine with an auxiliary power assisted by a power source such as a motor in a manual sizing machine in which a user pulls out a wall material by hand.

[0002]

2. Description of the Related Art A conventional wallpaper gluing machine is a manual type in which a user draws wallpaper from a rear portion of a main body using a force for manually pulling out wallpaper and transfers the glue with a gluing roll.
An automatic type in which a glue roll or the like is automatically driven using an electric motor or the like as a drive source to transfer and apply the glue is mainly used.

[0003] In the automatic type (electric type) having a driving force, the slip between the wallpaper and the sizing roll inside the apparatus is reduced as much as possible, and it is drawn in smoothly.
In addition, in order to discharge the glued wallpaper from the front side without any delay, a pinch roll for transmitting the driving force and pulling in the wallpaper from the outside is arranged at the entrance side (upstream side) of the gluing roll. A drive roll or the like to which a driving force is transmitted is also arranged on the side (downstream side) to carry the wallpaper.

On the other hand, the manual type uses the adhesive force of the glue roll to transfer and apply the glue, rotates the glue roll, and applies the rotational force to a doctor roll for adjusting the amount of glue or a drive roll on the outlet side. Although it is assumed that the transmission is performed to smoothly adjust the amount of the drawer and the amount of glue, the pinch roll on the entrance side is not provided because the resistance to the withdrawal force of the worker is provided.

[0005] In addition, there has been proposed a conventional wallpaper gluing machine which can be switched between a manual type and an electric type. However, in this conventional example, a motor unit serving as a driving source is removed at the time of manual operation. By removing the pinch roll on the entrance side which is necessary only for automatic operation, it can be used as a manual type.

[0006]

Since the conventional manual type does not require a power source such as a motor since the power is human, the apparatus itself is reduced in size, the overall weight is light, the cost is low, the portability is easy to carry, and the like. There is an advantage that it can be used even in a place where there is no power supply. However, the user needs labor to pull out the wall covering by hand, and the force and speed of the pulling by hand are not constant, so the relative speed (slip) of the wall covering on the gluing roll is not constant. However, there is a problem that the gluing accuracy is not uniform when viewed over the entire gluing surface.

[0007] Conversely, in a device provided with a power source such as an electric motor, the gluing work is automatically performed on the wall covering material, so that the user's labor is greatly reduced, and the wall covering inside the device is further reduced. Since the movement of the material is controlled to be constant, there is an advantage that the gluing accuracy is uniform over the entire gluing surface.

However, since the apparatus becomes heavier by the provision of such a power source, and further includes a pinch roll on the entrance side necessary for drawing the wall material into the apparatus, the apparatus is smaller than the manual type. There is a problem that the manufacturing cost is increased because the size is increased and many parts are required. In addition, since the power source is mainly an electric power source such as a motor, it cannot be used in places where electrical work has not been completed when using it at construction sites, etc. Many,
There was also a disadvantage that the operation of the automatic type was likely to be unstable.

[0009] On the other hand, the one that can be switched between the automatic type and the manual type is designed so that the operation at the time of automatic operation is completed.
Although it is provided with the entrance side pinch roll as a required configuration only in the electric type, when using this device as a manual type, remove this pinch roll one by one and further remove the drive source There is a drawback that switching is not easy.

[0010] As described above, if the pinch roll or the like inside is detached and attached, there is a problem that the removed roll is lost or is roughly handled and damaged at the construction site. The device body becomes larger and heavier than the manual type. Furthermore, in order to operate at the same level as the automatic type, in addition to making such an entrance side pinch roll indispensable, a large (high output) motor that only controls all rolls is required, The manufacturing cost itself cannot be reduced much compared to the automatic type. Furthermore, the work of attaching and detaching a relatively heavy motor or the like for switching each time places an excessive burden on the operator.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to solve the problems of the manual type and to reduce the labor of the user by providing auxiliary power. Aim. Another object of the present invention is to provide a wallpaper sizing machine which can selectively use a manual type and an automatic (with power assisted) type without a switching operation. A further object of the present invention is to provide a sizing machine which is easy to handle and does not increase the size of the sizing machine device body even if an auxiliary power is provided. Also, the present invention uses a conventional manual gluing machine,
It is an object of the present invention to provide a wallpaper sizing machine that can provide a simple auxiliary power with a minimum of modification.

[0012]

According to the first aspect of the present invention, in order to achieve the above object, a user pulls out a sheet-like wall covering pulled in from a rear portion of the main body by hand from the front side of the main body. Move along a predetermined path between a plurality of rolls including a gluing roll disposed inside the main body,
In a manual wallpaper sizing machine for continuously applying the glue in a glue tub disposed at the lower part of the main body to the back surface of the wall covering material by the gluing roll, a drawing force of the wall covering material is applied to the gluing roll. An assisting auxiliary power source and the auxiliary power source
The driving force of the glue is used as the rotational force of
Transfer to the attaching roll and the front in the pull-out direction.
One-way clutch machine that allows free rotation of the glue roll
To provide a manual wallpaper gluing machine which is characterized in that it comprises a structure.

The invention described in claim 1 of the present application is characterized in that an auxiliary power source for providing a driving force to a so-called manual type wallpaper sizing machine is provided. That is,
The wallpaper sizing machine of the present invention includes a plurality of sheets including a sizing roll disposed inside the main body by manually pulling out a sheet-like wall covering material drawn in from a rear part of the main body by a user from the front side of the main body. A manual wallpaper gluing machine that moves along a predetermined path between the rolls and continuously applies the glue in a glue tub arranged at the lower part of the main body to the back surface of the wall covering by the gluing roll is used as it is. Things. Therefore, the body of the gluing machine is not provided with a pinch roll on the entrance side as in the automatic type, but merely provides auxiliary power to the gluing roll and other movable rolls (interlocking rolls). As it is, the same operation as a so-called automatic gluing machine cannot be performed.

That is, even if power is simply applied to a so-called manual gluing machine, the wall covering material is drawn only by the adhesive force of the glue of the gluing roll because the pinch roll on the entrance side is not provided. However, in that case, the pull-in force (conveyance force due to adhesive force) at the gluing roll portion is not sufficient,
In particular, the slip of the wall covering occurs at the beginning of operation, and the rotation speed (surface speed) of the gluing roll becomes faster than the transport speed of the wall covering.

On the other hand, in the manual type gluing machine, the wall covering is conveyed through the apparatus by an operation of pulling the wall covering by hand (conveying force at the time of pulling out). The gluing roll rotates based on the adhesive force of the adhesive, and other rolls also rotate in conjunction with the rotation. For this reason, in a general manual gluing machine, during the gluing operation due to the pull-out force of the operator, the rotation speed (surface speed) of the gluing roll becomes slower than the transport speed of the transport material inside the apparatus. But there is a slip.

In the conventional manual type, the difference between the speed of conveying the wall covering material inside the sizing machine (particularly the sizing roll portion) and the rotation speed (surface speed) of the sizing roll is at most about 30%. The gluing precision is adjusted in consideration of the slipping action based on the speed difference. In other words, the device is configured on the premise that the wall covering material slips on the gluing roll in advance.
Also in this respect, the automatic type in which the slip hardly occurs has a different device configuration.

Here, the present invention provides a manual sizing machine with an auxiliary power source, but when operated with auxiliary power, the feed speed of the wall covering material is higher than the rotation speed of the sizing roll. Become slow. In other words, the glue roll is an auxiliary power mechanism that causes a slip with the wall material, and does not have a small difference in speed (a slip hardly occurs) required for a so-called automatic type.

This is because the auxiliary power is based on the premise that the same level of gluing accuracy as the manual type can be ensured, and the speed difference between the gluing roll and the wall covering material is
This is because the same gluing accuracy as that of the conventional manual type can be ensured within the range of about 30%, which is the speed difference of the conventional manual type, or less.

That is, even if the wall covering material is conveyed without the pinch roll on the entrance side by using the auxiliary power, if the speed difference on the gluing roll is suppressed to the same level as or less than that of the manual type, Gluing accuracy equal to or higher than that of the manual type can be obtained.

From the user's point of view, it is possible to perform the gluing operation easily or easily while securing the same or higher gluing accuracy as that of the conventional manual type without any effort to pull out the wall covering material. Therefore, the work labor is greatly reduced.

Further, the present invention is characterized in that an auxiliary power source for assisting the pulling force of the wall covering material with respect to the gluing roll is provided. It is also possible to simultaneously assist with the driving force from the driving source while performing the labor for extracting the material, and in this case also, the labor for extracting the wall material of the user is greatly reduced.

Here, if the user performs the work of manually pulling out the driving power from the auxiliary power source in the same manner as in the related art, it is clear that the pulling out force of the worker is reduced as compared with the conventional one, and further, the gluing is performed. The accuracy itself will be improved.

This is because, first, the labor for pulling out the wall covering material is increased by adding the labor of drawing out by the user's hand, so that the transport speed (transporting force) of the wall covering material at the gluing roll portion is changed by the user. It becomes faster according to the pulling force of the. As a result, the transport speed of the wall covering material, which is lower than the rotation speed (surface speed) of the gluing roll, also increases, so that the speed difference is smaller than in the case of using only the auxiliary power, and the degree of slip is reduced.

Further, in the case where the user only pulls by hand, the user repeatedly pulls and stops in accordance with the stroke of the hand. There are portions where the difference in gluing speed is large. However, if the work is performed while operating with the auxiliary power, the transport speed of only the auxiliary power is maintained at a minimum,
Differences in gluing speed and speed difference (degree of slip) over the entire gluing surface are reduced. As a result, the gluing accuracy is improved, even when viewed from the entire surface of the glued surface or when viewed partially, and variation between portions is reduced.

Here, since the main purpose is to reduce the labor of the manual wallpaper gluing machine, the electric motor or the like serving as a drive source may have a smaller output than an automatic type. That is, in an extreme case, the output of the auxiliary drive source alone can be used to the extent that the gluing roll and other movable (interlocking) rolls cannot be sufficiently moved. In other words, as long as the purpose is to assist the manual pull-out, a driving force may be transmitted to the glue rolls and the like as an integral part of the manual pulling force.
For example, if the driving source has a very small output, it may not move unless it is pulled by hand if the resistance at the start is large, but if you pull it out a little by hand at this place, then you will reduce the labor to pull by hand At the same time, the minimum conveying speed is maintained by the driving force during the operation, and the speed difference during the gluing operation does not significantly change as in the case of pulling by hand.

For this reason, an electric motor or the like as a drive source may have a small output, and a small and light one can be used. Therefore, the enlargement of the apparatus can be minimized and the weight can be reduced. Furthermore, the roll configuration of the conventional manual type sizing machine can be applied as it is, and it is not necessary to newly provide the entrance side pinch rolls etc. which are necessary for the automatic type, so that an inexpensive motor can be used. Also, the manufacturing cost of the apparatus main body can be significantly reduced as compared with the automatic type.

When a power source such as a low-output electric motor is used, the idling resistance is extremely small, so that even if the power source is not operating, the wall material is manually pulled out. It is possible. Therefore, even in the case of an auxiliary power type, there is a case where normal use as a manual type can be performed without a switching operation. In addition, it is preferable that such an auxiliary power source be detachable in consideration of reduction in the overall weight during transportation, safety in cleaning the device, and the like.

On the other hand, at the beginning of the work of drawing out the wall material with the manual type gluing machine, the heavy gluing roll and the rolls interlocking with the heavy glue roll must be operated from a stationary state, so a large amount of labor is required. If an auxiliary power source is provided as in the present invention, the user's labor is not required from the beginning, or the user can work with a very small force even when performing the pull-out operation.

In the middle of the gluing operation, the rotational moment of inertia of each roll also acts, so that the wall covering material is conveyed in sequence. The material can be transported. Further, when the transport speed is slow only by the transport of the auxiliary power source, the worker may pull out at a speed higher than the driving speed by the auxiliary power source.

Alternatively, if only manual operation is performed, the stroke is repeated a number of times from the stroke of the hand, that is, the position where the user reaches out of the work position and grasps the wall covering material, to the position where the user cannot pull the hand backward. And the wall covering material is repeatedly transported and stopped each time.

In this case, there is a difference in the state of gluing between the portion in contact with the gluing roll during conveyance and the portion in contact with the gluing roll during stoppage. I can't work.

However, if an auxiliary power source is provided as in the present invention, the user continuously shakes the wall covering material and pulls it lightly to maintain a substantially constant transport speed (see FIG. 1). Gluing work can be performed with the speed difference small during the gluing work), so that one gluing operation can be completed in less time than the manual mold alone, and the gluing is much more uniform than the manual mold over the entire gluing surface. Work can be done.

[0033] In the manual wallpaper gluing machine according to the first aspect of the present invention, the driving force from the auxiliary power source is transmitted to the gluing roll as a rotational force for drawing out the wall covering, and the gluing is performed in the drawing direction. It further includes a clutch mechanism that allows the roll to play independently .

According to the present invention, by providing a so-called clutch mechanism, it is possible to maintain the state of transmission of power from the auxiliary power source and the state of idle rotation of the gluing roll and other interlocking rolls. That is, during the operation of the auxiliary power source, the driving force can be transmitted to the gluing roll as a rotational force for drawing out the wall covering material, and the gluing roll in the pulling-out direction can be transmitted regardless of the driving of the auxiliary power source. Can be performed independently, so that the user can pull out the wall material in the same manner as in a normal manual type, regardless of whether the drive source operates.

That is, even if a small-sized and low-output motor is used, there is an idling resistance. Therefore, in order to eliminate the resistance, a clutch mechanism is provided in a process of supplying a driving force from a driving source. . This is because, for example, by providing a so-called one-way clutch in the power transmission mechanism portion of the drive system, an interlocking roller such as a gluing roller can idle in the transport direction of the wall covering regardless of the operation of the power source. Alternatively, if a so-called clutch-equipped motor or the like that can select between a power transmission state and a disengagement state is used, the clutch portion constitutes the clutch mechanism of the present invention. Thereby, the operation of pulling out the wall covering material by the operator can be performed in the same manner as the ordinary manual type regardless of the operation of the auxiliary power source.

Further, when the driving force from the auxiliary power source is transmitted (transmitted), even if the conveying speed is low, if the one-way clutch mechanism is provided, for example, the user can be further operated. It can be withdrawn quickly. Therefore,
The power source is sufficient to assist the pull-out force, the working efficiency will not be lower than that of the manual type, the pull-out effort itself will be significantly reduced, and the time required for the gluing operation will be shortened.

In addition, since the motor can be idled by being separated from the power source by the clutch mechanism, the idling resistance of the power source such as a motor is negligible. There is an advantage that can be used as usual, and when using that power,
There is also an advantage that a large auxiliary power can be obtained.

The present second aspect of the present invention described provides a claim 1 manually wallpaper pasting machine, wherein the auxiliary power source, a user of the wallpaper pasting machine includes an operation portion for operating a foot It is characterized by having.

In the present invention, since the power source is merely auxiliary, it is preferable that the user performs an operation of assisting the pulling out of the wall covering. This is the case where the operation of folding the wall material with both hands lightly attached to both side portions of the glued wall material, and the operation of consciously pulling out the wall material are performed. For example, at the beginning of the drawing operation, pull out lightly to make the drive from the power source smooth, or during the gluing work, pull lightly enough to reduce the slip of the wall covering on the gluing roll, etc. In some cases. It goes without saying that even when the user gently assists or pulls out consciously during these operations, the required force is much smaller than that of a conventional simple manual type.

However, when operating the auxiliary power source,
For example, some operation such as operation of a drive switch is required.However, in a gluing machine with auxiliary power such as the present invention, an operation of pulling a wall covering material by hand may be performed. In this state, a sub-operation of the operation of the power source is required.

According to the present invention, since the operating portion of the power source is provided with an operating portion that can be operated with an empty foot, not the closed hand of the user, the operation of the power source and the processing of the wall material are performed. There is no need to perform a complicated and cumbersome operation of simultaneously performing the operation by hand. In other words, by performing the operation with the unoccupied feet, the hand work can be concentrated only on the processing of the wall covering material, so that the operation of the apparatus and the gluing operation are facilitated.

The operation section is not particularly limited as long as it has a structure that can be operated by foot. For example, a foot switch that operates by stepping on the sole of the foot, a switch that can be operated with a knee, or the like, may be a structure that can be operated with the hands closed. The following can be considered as an operation unit using a foot such as a foot switch.

One aspect of the present invention is that the operation unit with the foot controls only the on / off of the power source, and is an on / off switching type by a single operation of the foot.
In this case, the user operates the power source by operating the foot at the start of the work, and stops the power source by operating the power source again just before the end. Since the power source can be operated by one operation at the beginning and one at the end, it can be easily operated.

According to another aspect of the present invention, the operation unit with the foot controls only the on / off of the power source, and the drive source operates during the operation with the foot, and the operation with the foot is stopped. The drive source stops. For example, the drive source operates only while depressing with a foot switch, etc.
The user only needs to perform an operation such as depressing a foot switch only when he / she wants to operate the drive source. When the operation is completed, the user can easily perform an operation such as stopping the operation with the foot, for example, stopping depressing the foot switch.

According to still another aspect of the present invention, the operation unit with the foot is a variable foot switch capable of changing the output of the power source in accordance with the amount of depression. In this case, what is necessary is just to be able to adjust the output according to the so-called accelerator type depression angle, and the user can change the output (transport speed) according to his / her preference. In order to prevent a malfunction, it is preferable to provide a reverse biasing means for returning when the stepped foot is released.

Next, in the invention according to claim 3, wherein
Item 3. The invention according to Item 1 or 2 , wherein the auxiliary power source further includes an operation control unit that stops after operating a predetermined amount based on a preset value input in advance.

That is, the gluing operation by the gluing machine is to glue a wall covering material having a predetermined length in accordance with the height of the wall or the like. As the glued wall covering is folded, the user is busy with such secondary tasks.

According to the present invention, the auxiliary power source is automatically stopped after receiving at least a start signal based on the set value once set, operating for a predetermined amount (length or time, etc.). . Thus, if the user gives only a signal for starting operation by, for example, pressing an operation switch or the like, the user stops after operating for a predetermined time, length, and another predetermined amount, so that the present invention The operation of such a device is simply to input an initial start signal with a switch or the like.

The predetermined amount of the operation control means may be, for example, a predetermined time (for example, 5 seconds or 10 seconds) as long as it is a time. In this case, the gluing length can be generally determined in consideration of the transport speed and slippage of the apparatus driven by the auxiliary power, so that the transport length when the apparatus is driven for that time is a rough guide.

Alternatively, when the gluing length is entered,
The operation time may be calculated back from the drive time according to the length and the transport speed. In this case, a drive time processing unit that calculates the operation time according to the value of the length input in advance may be provided. It is preferable that the drive be stopped before reaching the input gluing length in consideration of a slip or the like. This is for preventing unnecessary gluing, and if it is not enough, it may be pulled out by hand as in a normal manual type. Also in this case, the wall covering can be easily pulled out with the clutch mechanism.

On the other hand, when a glue length detecting means for detecting the glue length of the wall covering is separately provided, the predetermined amount can be defined by the length. That is, the driving of the power source is controlled in conjunction with the calculated distance value of the length detecting means. Also in this case, for example, the length may be a reference length such as 1 m, 2 m, or the like.

Alternatively, the gluing length may be input in advance, and the operation may be controlled by setting a predetermined amount by the length so as to stop when the length is reached. In this case as well, it is necessary to stop before reaching the entered length as in the previous term, and finally make fine adjustments manually, as this will not waste unnecessary gluing work and waste wall material and glue. preferable.

According to still another aspect of the present invention, the operation section of the operation control means has a foot operation section as in the third aspect of the present invention. To start operation. In this case, once the device is operated with the foot, the device automatically stops after operating by a predetermined amount. In this case, the predetermined amount can be, for example, an operation time or a corresponding transport distance, but if the gluing length is determined, the gluing distance can be determined by the rotation angle. Become. Alternatively, the operation may be stopped when a detection value from another length measuring means reaches a preset gluing length.

In still another embodiment, the operation unit of the operation control means is provided with a manual operation unit. In a single gluing operation, if the operation unit is manually operated immediately before the start of the operation,
After that, the operation automatically stops when a predetermined amount of operation is performed. For this reason, during the gluing operation that requires manual operation, the user's hand is not necessary for operating the apparatus, and only the processing of the glued wall covering can be performed.

However, it is only an auxiliary power source,
The slip on the glue roll cannot be completely prevented, so the approximate distance may be a guide.However, if the stop is controlled before the glue length is reached, the glue operation itself in any case There is no problem, and finally the fine adjustment of the gluing length may be performed only manually.

In the case of a foot switch which is operated by stepping on the foot, it is preferable that the foot switch be connected to a position near the user's foot separated from the main body by a cable or other signal transmission means. This is to facilitate the operation of the user.

According to the fourth aspect of the present invention, a user pulls out a sheet-like wall covering material that is pulled in from the outside of the main body from the front side of the main body, so that the gluing roll disposed inside the main body is formed. In a wallpaper sizing machine that moves along a predetermined path between a plurality of rolls including, and continuously applies the glue in a glue tub disposed at the lower part of the main body to the back surface of the wall covering material by the sizing roll, The main body is composed of an upper structure and a lower structure that are configured to be openable and closable, and the gluing roll is disposed on the lower structure, and on the upstream side of the gluing roll, from the upper surface side of the wall covering material. A holding stay that is in contact with and does not interlock with another roll is disposed on the upper structure, and a drive roll that is in contact with the upper side of the wall covering material and interlocks with the gluing roll is provided downstream of the gluing roll. And a leveling roll which is in contact with the lower side of the wall covering material and is interlocked with the gluing roll on the downstream side thereof, and assists the gluing roll in pulling out the wall covering material. A power source is detachably provided to the main body, and a transmission unit of a driving force from the auxiliary power source controls rotation of an output shaft of the auxiliary power source in a drawing direction of the wall material. A one-way clutch mechanism that transmits the rotational force to the glue roll and allows the glue roll to rotate independently in a direction relatively opposite to the rotation of the output shaft is provided. ,
There is provided a manual gluing machine with an auxiliary power, comprising a foot switch operated by a foot of a user of the wallpaper gluing machine.

The present invention is a preferred embodiment of the present invention, and has a roll configuration substantially the same as that of a so-called manual type sizing machine, and does not have a pinch roll on the entrance side as in a so-called automatic type. It is. The gluing roll is interlocked with a doctor roll for adjusting the amount of gluing provided on the lower structure so as to be in contact with the gluing roll, but does not contact the wall covering.

At the entrance side, the pressing stay comes into contact with the holding stay on the upstream side of the gluing roll. This is a roll or a round bar that does not interlock with other rolls, and does not contribute to the transport of the wall covering. This is for pressing the wall covering material downward from the front upper side to increase the contact angle of the wall covering material to the gluing roll.

The drive roll on the downstream side of the gluing roll presses the wall covering material from above on the downstream side to increase the contact angle of the wall covering material with the gluing roll, and at the same time in conjunction with other rolls. Since it is driven, it slightly contributes to the transmission output of the wall covering. However, there is no glue on the top side,
Since the pressing force is not so strong, the sending power is small, but it contributes to the auxiliary.

Further downstream, the leveling roll is in contact with the gluing surface (the lower surface of the wall covering material) and interlocks with other rolls, but mainly contributes to leveling of the glued glue. ,
Transmission power also contributes slightly.

The auxiliary power source has a drive unit such as an electric motor and is removably provided on the main body. If the work site can use electricity, it may be attached.
In places where electricity cannot be used, it may be used manually. Since a one-way clutch mechanism is provided, there is no inconvenience in using it as a manual type even with the auxiliary power source attached. Further, if the transport speed at the auxiliary power source is low, the user can pull out at a higher speed.

The operation of the auxiliary power source is performed by the user using a foot switch, and this foot switch can be applied to any of the above-described operation units using feet. As long as the foot switch is installed on a floor near the work position of the user on the front side of the gluing machine, the user can easily use the auxiliary power source during the gluing operation. Can be operated. An arrangement of about 50 to 100 cm in front of the device corresponds to this, but up to that, if a signal transmission means such as a cable or communication is provided, it can be installed in an arbitrary place that is easy to use according to the user's preference. .

In the invention according to claim 5 of the present application, the user pastes the sheet-like wall covering material pulled in from the rear portion of the main body from the front side of the main body, thereby forming the gluing roll disposed inside the main body. In a manual wallpaper sizing machine which moves along a predetermined path between a plurality of rolls including a plurality of rolls and continuously applies the glue in a glue tub arranged at the lower part of the main body to the back surface of the wall covering material by the gluing roll. And a mounting portion for an auxiliary power source for detachably holding an auxiliary power source for assisting a pulling force of the wall covering material in a conveying direction with respect to the gluing roll. Provide an accessory machine.

The present invention relates to a sizing machine having substantially the same roll configuration as a conventional manual wallpaper sizing machine, but is characterized in that it has an attachment portion for an auxiliary power source.
The mounting portion only needs to have a structure to which the auxiliary power source can be mounted, and the auxiliary power source can be mounted as needed. In this case, if the auxiliary power source side has a driving source such as an electric motor, a transmission unit for transmitting the driving force to the gluing roll, and a mounting unit that matches the mounting unit of the gluing machine. , Can be installed as needed. More preferably, if the above-mentioned clutch means is provided on either the auxiliary power source side or the mounting portion side of the gluing machine, it can be used as a manual type even in the mounted state. Needless to say, when the auxiliary power source is not attached, the device can be used as a normal manual gluing machine.

According to the sixth aspect of the present invention, the sheet-like wall covering material drawn in from the rear side of the main body is moved along a predetermined path between a plurality of rolls including a gluing roll disposed inside the main body. In a wallpaper sizing machine for continuously applying the glue in a glue tub arranged at the lower part of the main body to the back surface of the wall covering material by the gluing roll, the conveying direction of the wall covering material with respect to the gluing roll A power source for applying a pulling force to the glue roll, and a driving force from the power source is transmitted to the gluing roll as a rotational force in a pulling-out direction of the wall covering material, and the gluing roll rotates freely in the direction. And a clutch mechanism that permits the use of a wallpaper gluing machine.

In the present invention, a clutch mechanism that allows idle rotation of the glue roll in the transport direction is provided as a transmission structure from the power source to the glue roll or another interlocking roll regardless of what is called a manual type or an automatic type. Are
Even if there is no driving force, manual gluing work by human power is ensured.

Even when it is difficult to secure a power supply at the work site, the minimum operation state is ensured. However, in the case of a specialized automatic type, the resistance of a pinch roll or the like provided at the entrance side is reduced. Although slightly larger, the pull-out resistance of the wall covering is significantly reduced by the clutch mechanism.

In all of the above-mentioned inventions, the transmission of the driving force from the auxiliary power source is preferably transmitted directly to the heaviest gluing roll among the interlocking rolls, since energy loss is small. If the driving force is transmitted to any of the interlocking roll mechanisms including the roll, the driving force is consequently transmitted also to the gluing roll, and thus there is no particular limitation.

Specifically, an output gear interlocking with the output shaft of the auxiliary power source is provided at an interlocking gear portion with another roll provided at the end of the gluing roll for an interlocking mechanism of a plurality of rolls.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram showing the overall configuration of a manual wallpaper gluing machine with an auxiliary power source according to one embodiment of the present invention.

The sizing machine main body 1 uses the structure of a conventional manual sizing machine as it is, and is mounted on a foldable leg 5 for holding the main body at a predetermined height. I have.
A power unit 3 driven by a small electric motor as an auxiliary power source is detachably provided outside the side frame of the main body, and a foot switch 7 connected by a cable of a predetermined length. Is the operation unit with the foot of the auxiliary power source (power unit 3).

The foot switch 7 controls the on / off of the electric motor built in the power unit 3, and controls the on / off of the drive source by repeatedly turning on the pedal once, depressing the pedal once again, and then repeating these steps. . Note that in other forms, there is a type in which the switch is turned on only while the driver is depressing and is turned off when the switch is released, but in this case, the operation of turning on and off is easier.

The power unit 3 is, as shown in FIG.
From the housing 201 in which the electric motor and the like are built, the output shaft 203
The bearing shaft 205 is fixedly attached to the output shaft. On its outside, a one-way clutch bearing 20 as a clutch means is provided.
The output gear 209 is provided by being press-fitted on the outside thereof, and is fixed by a retaining ring 210.

This one-way clutch gear (one-way clutch bearing 207 + output gear 209) receives the rotational force of the output shaft 203 in the direction in which the wall material is drawn out (the direction in which the gluing roll is rotated in the transport direction). The driving force is transmitted to the gear 207 to rotate the gear 207 integrally.

Further, rotation in the direction opposite to the output shaft (idling in the transport direction) is allowed.
When the output shaft is stopped, the output gear 209 is made to rotate freely with respect to the output shaft by itself, so that the output gear 209 can be independently rotated in the pull-out direction. Further, the output shaft 203
Is rotating in the same direction (idling) at a speed faster than that rotation.

Alternatively, as another embodiment, a so-called clutch-equipped motor may be used as the clutch mechanism. This may be any structure that allows the output shaft to rotate freely regardless of whether the motor is operating or not, such as disengaging the motor-side clutch. Thus, a manual gluing operation (drawing operation of the wall covering material) can be performed regardless of the driving of the motor.

As shown in FIG. 2B, a power cord 211 and an insertion port 213 for a connection cable 9 to the foot switch 7 are provided on the back side of the housing 201, and the front side (user side) is provided. ) Is provided with a power switch 215. This power switch is a push-in switch, and is configured such that an indicator lamp is turned on at a switch portion when power is supplied.

The main body 1 is provided with a drive source mounting hole (not shown) having a size through which the output gear 209 passes at a predetermined position on the right side surface, and the output gear 209 meshes with the gluing roll gear 221 of the gluing roll 301. In the state, the power unit 3
Has a fixing structure for fixing to the main body 1. The structure of this fixing structure is not particularly limited as long as the power unit 3 as an auxiliary power source is held in a state where the output gear 209 normally meshes with the gluing roll gear 221 and interlocks with each other.

As shown in FIG. 3, the structure of the conventional manual gluing machine is used as it is for the rolls and gears in the main body 1. The main body 1 includes an upper structure 331 and a lower structure 33.
3 and connected by a rear rotating shaft 335, and the front portion of the upper structure is rotated upward about the rotating shaft 335 to be opened. These are normally held in a closed state by the lock member 337, but are opened when the wall covering is mounted or removed.

The lower structure 333 has a glue tub integrally provided therein, and a roll or the like is supported on a frame side plate on the side outside. Frame side plate 34 of lower structure 333
1 is a long hole 3 in which the gluing roll 221 is open at the top.
The bearing 43 is mounted via a bearing member, and is removed and washed at the time of washing after use.

Gluing roll 301 of frame side plate 341
A doctor roll 303 for adjusting the amount of gluing is disposed close to the gluing roll 301 on the upstream side of the device.
Gluing amount can be changed.

Gluing roll 301 of frame side plate 341
On the downstream side, a leveling roll 307 is supported via a bearing member by a long hole 347 having an open top, and this is also removed and washed at the time of washing.

On the upper structure, an upstream holding stay 309 is fixed to a position where the upstream holding stay 309 is pressed from above the wall covering material on the upstream side of the gluing roll 301, and the wall covering material is fixed to the upper end of the gluing roll 301 by the upstream holding stay 309. The sheet is sent to the gluing roll 301 from a position below the copy position.

Similarly, at a position downstream of the gluing roll 301 of the upper structure and upstream of the leveling roll 307, a drive roll 305 is disposed at a position where the wall covering material is pressed from above, and The contact angle of the material is increased. Further, a downstream holding stay 310 is provided at the most outlet side.

Here, the frame side plate 34 on the right side of the main body portion
Gears for interlocking the gluing roll 301 and the doctor roll 303 are provided outside the 1 (glue tub) as a glue roll gear 221 and a doctor roll gear 223, respectively, and mesh with each other.

Although not shown, a gluing roll 301 and a drive roll 3 are provided outside the left frame side plate.
A gear for interlocking the leveling roller 05 and the leveling roll 307 is provided on each of the roll shafts, and meshes with each other so that a rotational force is transmitted and interlocked.

As is apparent from this figure, no pinch roll for taking in the wall material is provided at the entrance side of the main body 1, and even if the driving force is applied as it is, the normal operation is performed. It is a difficult structure.

Here, when the power unit 3 is attached to the main body 1, the output gear 209 becomes the glue roll gear 221.
Are held in a position where they mesh with each other and interlock with each other. The arrow in the figure indicates the rotation of the wall covering material in the pulling-out direction. In the direction of the arrow, the idle of the output gear 209 is allowed by the function of the one-way clutch bearing 207. The function equivalent to the manual type is maintained as it is.

Next, a method of using this device will be described. A sheet-like wall covering wound on a roll is attached to the cross support portion 141 at the rear of the main body, one end is pulled out, and the upper structure 331 of the main body 1 is opened and pulled up to the front of the main body, and the upper structure is moved. Close and lock 331. In this state, pull out the wall covering material until the glued part comes out, and cut off the unnecessary part.

As in the case of using a general gluing machine, a gluing operation of a desired length is performed while looking at a scale (not shown) for measuring the gluing length.
First, when the user depresses the foot switch 7 while grasping the tip of the wall covering material by hand, the motor operates and the driving force in the pull-out direction is transmitted to the gluing roll 301 and other interlocking roll groups.

[0092] For this reason, the user can pull out the wall covering material with a very small force, and the working labor is greatly reduced. This is much less labor than the conventional manual type in which the wall covering material is pulled out only by the user's force and the glue roll and other interlocking roll groups are operated at that time.

At this time, if the user does not pull the wall covering material lightly, the wall covering material slightly slips on the gluing roll 301 only by pulling in with the adhesive force of the gluing roll 301. The difference is kept to the same level or less than the conventional manual type. Conversely, the driving force is transmitted from the driving source so as to be equal to or less than the slip allowed by the conventional manual gluing machine. Specifically, the gear ratio and the initial operation are configured to be gradually accelerated, but may be determined as appropriate according to the specific structure of the device, the output of the motor to be used, and the like.

That is, in this apparatus, the gluing operation of the wall covering material can be performed only by the auxiliary power source, but the gluing accuracy affected by the slip is suppressed to the same level as or less than that of the conventional manual type. Can be However, since the driving force is applied throughout the gluing operation and continuous processing can be performed,
Since there is no speed difference during the operation of pulling and stopping as in the manual type, the gluing accuracy is much more uniform than that of the manual type when viewed over the entire gluing surface.

Further, in order to reduce the influence of the slip, the user may simultaneously carry out the work of pulling out the wall covering material. Since this work complements the driving of the auxiliary power source, it is only necessary to pull in the wall covering very lightly. It is a feeling of assisting the delivery of equipment.

When the desired length is approached and the foot length is approached, if the foot switch 6 is depressed again, the motor stops and the driving force is not transmitted, and the feeding stops if the user does not pull out. Even in this state, the idle rotation of each roll in the feeding direction is allowed by the one-way clutch mechanism, so the user finally pulls out the wall covering while checking the gluing length of the scale and glues it. The length may be adjusted.

In the case of performing long gluing, there is a case where it is necessary to quickly pull out the glue in order to speed up the work. Even in such a case, the user can pull out the wall covering at a speed higher than the rotation speed (delivery speed) of the drive source in the case of urgency due to the action of the one-way clutch mechanism. , Speed problems can be solved. Also in this case, the speed change from the state where it started once can be easily done with relatively small force due to the inertia of the roll, and the operator can pull out the transfer speed of the wall covering by rotating the glue roll. Since the speed is close to or slightly higher than the speed (surface speed), the slip here is also small and does not affect the gluing accuracy.

In the above embodiment, the foot switch is of the on / off switching type. However, a foot-operated type in which the drive source operates only while the foot is depressed and stops when the foot is released is used. Is also good. In the case of using the step-on type, the user can also obtain an auxiliary driving force by depressing the foot switch as needed during the work.

Alternatively, a timer may be provided as the operation control means so that once the operation is started, the operation is automatically stopped after a lapse of a predetermined time (a length corresponding to the operation). Alternatively, it is also possible to adopt a configuration in which the operation is stopped when a predetermined length is pasted, in conjunction with the measuring means of the pasting length. In any case, since the user only needs to perform an initial operation such as stepping on the operation unit before starting the gluing, there is an advantage that the operation is easy and the user can concentrate on the auxiliary operation such as the processing of the wall covering material.

[0100]

As described above, according to the present invention,
Since the manual gluing machine is provided with the auxiliary power source, the work labor of the user can be greatly reduced. Since the auxiliary power source can be used even with a small and low output, it is possible to minimize the increase in the size and weight of the device, and the manufacturing cost can be significantly reduced as compared with the automatic type.

In the present invention, the provision of the clutch mechanism enables the general use of a sizing machine as a manual type, and furthermore, a manual adjustment of the final length adjustment and an auxiliary power source. Even when the speed is low, a quick gluing operation can be performed with a small force of the user's hand.

Further, by providing the auxiliary power source with a foot-operated part, even if the hand for hand operation is inconvenient as in the case of the manual type, the operation can be performed with an empty foot, so that it is efficient. Therefore, a gluing machine with an auxiliary power source can be easily used.
