[Technical Field]

[0001] The present invention relates to an automatic wallpaper pasting machine for automatically applying paste to the backside of wallpaper (cloth) for pasting it on, for example, a ceiling or wall, and includes a substantially rectangular horizontal support for supporting the wallpaper pasting machine body. To provide an automatic wallpaper pasting machine equipped with a support frame and a leg frame pivotally supported on a horizontal support frame so as to be openable and closable, the automatic wallpaper pasting machine preventing the leg frame from accidentally opening (spreading) relative to the horizontal support frame during transportation and installation. [Background technology]

[0002] Conventionally, when installing wallpaper in interior construction projects, such as new construction and renovations, professional interior construction contractors often bring a dedicated automatic wallpaper pasting machine to the construction site and use the automatic wallpaper pasting machine to apply glue to the backside of the wallpaper.

[0003] FIG. 17 is a perspective view of a conventional automatic wallpaper pasting machine 200 used for such wallpaper application.

[0004] As shown in Fig. 17, a conventional automatic wallpaper gluing machine 200 includes a wallpaper gluing machine main body 202. The wallpaper gluing machine main body 202 also includes a roughly box-shaped main body frame 204 that is open at the top so that the transport of wallpaper being glued can be seen.

[0005] Furthermore, a base frame 201 is provided below the main frame 204, and this base frame 201 has an approximately rectangular horizontal support frame (not shown) that supports the wallpaper pasting machine main body 202 (main frame 204).

[0006] 17, a pair of leg frames 206 are provided below both ends of the left and right sides of the main frame 204, and are attached to the horizontal support frame so as to be able to open and close.

[0007] In addition, for ease of transport, the base frame 201 and the wallpaper pasting machine main body 202 (main body frame 204) are configured to be detachable by fastening members such as so-called "snap locks" (not shown).

[0008] 17, the main body frame 204 is made up of an upper frame 208 and a lower frame 210. The upper part of the upper frame 208 is provided with a pair of handles 208c spaced apart in the left-right direction.

[0009] By grasping and operating this handle 208c, as will be described later, wallpaper G can be placed on the wallpaper pasting machine main body 202, and for maintenance purposes, the machine can be opened and closed as shown by arrow I in Figure 17, with a pivot axis (not shown) as the center of rotation relative to the lower frame 210.

[0010] Although not shown, the upper frame 208 and the lower frame 210 are provided with locking devices such as so-called "snap locks" to secure the upper frame 208 in a closed position relative to the lower frame 210.

[0011] The upper frame 208 also has side plate portions 208a and 208b that form the left and right side portions.

[0012] On the other hand, as shown in Figure 17, a lockable roller 214 is provided at the lower end of the leg frame 206, which makes it possible to move and position the automatic wallpaper gluing machine 200 to the desired location.

[0013] Furthermore, as shown in Figure 17, the lower frame 210 has side plate portions 210a and 210b that form the left and right side portions. The automatic wallpaper pasting machine 200 includes a drive unit 216 that incorporates a drive device such as a gear linkage mechanism and also incorporates a control device for controlling the automatic wallpaper pasting machine 200 and a drive motor.

[0014] 17, there is provided a display and operation panel unit 218 for displaying the measured wallpaper length (measurement result), controlling the drive motor, and inputting information such as the type of wallpaper G. The drive unit 216 is either detachably attached to one side plate 210a of the lower frame 210 or is fixed thereto.

[0015] Furthermore, as shown in FIG. 17, the pair of leg frames 206 are provided with a wallpaper roll mounting stand 224 for rotatably and detachably mounting a wallpaper roll 222 around which wallpaper G is wound.

[0016] Then, although not shown, by the gluing mechanism of the conventionally known wallpaper gluing machine main body 202, the wallpaper G sent out from the wallpaper roll 222 of the roll mounting stand 224 passes through the wallpaper gluing machine main body 202 of the automatic wallpaper gluing machine 200, and glue is applied to the back surface GB of the wallpaper G.

[0017] Then, as needed, the wallpaper G, with the anti-drying film B and cutting tape C attached to the adhesive surface of the back surface GB of the wallpaper G, can be wound up manually or automatically by a separate winding device not shown.

[0018] Alternatively, as shown by the dotted lines in Figure 17, the wallpaper receiving section 220 is an inclined, roughly plate-shaped section provided between a pair of leg frames 206, or is configured to be manually folded down below the wallpaper gluing machine main body 202 which receives glued wallpaper G discharged from the wallpaper discharge section 219 on the front side in Figure 17 and is placed directly on the floor.

[0019] [Patent Document 1] Patent No. 4947629 Summary of the Invention [Problem to be solved by the invention]

[0020] Incidentally, when a dedicated automatic wallpaper pasting machine is brought to a construction site and used to apply glue to the backside of wallpaper, when the machine is transported to the construction site, the fastening state using fastening members such as so-called "snap locks" is released (not shown), and the base frame 201 and the wallpaper pasting machine main body 202 (main body frame 204) are loaded separately onto a truck or the like for transportation.

[0021] At this time, the base frame 201 is in a state where the pair of leg frames 206 are closed (closed leg state) with respect to the horizontal support frame as shown by arrow J in FIG.

[0022] When the base frame 201 is unloaded from a truck or the like and transported to a construction site, the pair of leg frames 206 are in an open position (spread leg position) relative to the horizontal support frame, as shown by arrow J in Figure 17.

[0023] The wallpaper pasting machine main body 202 (main body frame 204) is then fixed onto the base frame 201 in a fastening state using fastening members such as so-called "snap locks," and the automatic wallpaper pasting machine 200 is assembled.

[0024] In this state, the automatic wallpaper pasting machine 200 is transported to the application site using the lockable rollers 214 provided at the lower ends of the leg frames 206.

[0025] Incidentally, Patent Document 1 (Patent Publication No. 4947629) discloses a wallpaper gluing machine configured so that a pair of leg frames 206 can be securely locked to the horizontal support frame in an open state (open leg state) or a closed state (closed leg state).

[0026] The wallpaper pasting machine of Patent Document 1 makes it easy to open and close the legs, and also makes it possible to reliably lock the leg frame 206 relative to the horizontal support frame when the legs are in the open and closed positions.

[0027] However, in the automatic wallpaper gluing machine 200 of Patent Document 1, when the leg frame 206 is unlocked from a state in which it is locked in a closed position (closed leg position) relative to the horizontal support frame, the leg frame 206 becomes free relative to the horizontal support frame.

[0028] As a result, the leg frame 206 swings open by 90 degrees due to a pendulum motion caused by its own weight. If the leg frame 206 suddenly swings from a closed state (closed legs state) to an open state (open legs state) in this way, a strong impact occurs when opening, which may hit the foot or trap a finger or other part, resulting in injury.

[0029] In view of the current situation, the present invention aims to provide an automatic wallpaper gluing machine in which, even when the leg frame is unlocked from a locked closed state (closed leg state), the leg frame does not swing open 90 degrees due to its own weight in a pendulum motion, but slowly moves from the closed state (closed leg state) to the open state (open leg state).

[0030] The object of the present invention is to provide a safe and convenient automatic wallpaper pasting machine in which the leg frame does not suddenly change from a closed state (closed leg state) to an open state (open leg state), no strong impact occurs when opening, the leg frame does not hit the feet, fingers are not caught, and there is no risk of injury. [Means for solving the problem]

[0031] The present invention has been invented to achieve the above-mentioned problems and objects of the prior art. The automatic wallpaper pasting machine of the present invention comprises: a wallpaper pasting machine main body configured to automatically apply paste to the backside of wallpaper; a horizontal support frame that supports the a leg frame pivotally supported on the wallpaper pasting machine body so as to be openable and closable; and an opening / closing control device that controls the opening and closing of the leg frame relative to the wallpaper pasting machine body, The opening / closing control device includes a biasing member that biases the leg frame in a direction to close the leg frame relative to the wallpaper pasting machine body. An opening / closing biasing mechanism having and The load generated when the leg frame is opened or closed is distributed in the horizontal and vertical directions, and the biasing member is arranged so that the biasing force is generated in the horizontal direction. The biasing force of the biasing member is such that the leg frames are slowly biased by their own weight from the closed leg state to the open leg state.

[0032] By configuring it in this manner, it is provided with an opening / closing control device that controls the opening and closing of the leg frame relative to the wallpaper pasting machine main body, and the opening / closing control device is configured to urge the leg frame in a direction closing relative to the wallpaper pasting machine main body.

[0033] Therefore, even when the leg frame is unlocked from a locked closed state (closed leg state) due to the biasing force that biases the leg frame of this opening / closing control device in the closing direction relative to the wallpaper pasting machine body, the leg frame will not swing open 90 degrees due to its own weight in a pendulum motion, but will slowly move from the closed state (closed leg state) to the open state (open leg state).

[0034] This prevents the leg frame from suddenly changing from a closed state (closed leg state) to an open state (open leg state), and no strong impact occurs when opening, so the leg frame does not hit the feet, fingers are not caught, and there is no risk of injury, making it possible to provide a safe and convenient automatic wallpaper gluer.

[0035] In addition, the automatic wallpaper pasting machine of the present invention comprises: a wallpaper gluing machine body configured to automatically apply glue to the backside of wallpaper; a base frame supporting the wallpaper pasting machine body, The base frame has a substantially rectangular horizontal support frame that supports the wallpaper pasting machine body, and a leg frame that is pivotally supported on the horizontal support frame so as to be openable and closable, An opening / closing control device for controlling the opening and closing of the leg frame relative to the horizontal support frame is further provided, The opening and closing control device is a biasing member that biases the leg frame in a direction to close the leg frame relative to the horizontal support frame; The biasing force of the biasing member is such that the leg frames are slowly biased by their own weight from the closed leg state to the open leg state.

[0036] By configuring it in this manner, an opening / closing control device is provided that controls the opening and closing of the leg frame relative to the horizontal support frame, and the opening / closing control device is configured to urge the leg frame in a closing direction relative to the horizontal support frame.

[0037] Therefore, even when the leg frame is unlocked from a locked closed state (closed legs state) due to the biasing force that biases the leg frame of this opening / closing control device in the closing direction relative to the horizontal support frame, the leg frame will not swing open 90 degrees due to its own weight in a pendulum motion, but will slowly move from the closed state (closed legs state) to the open state (open legs state).

[0038] This prevents the leg frame from suddenly changing from a closed state (closed leg state) to an open state (open leg state), and no strong impact occurs when opening, so the leg frame does not hit the feet, fingers are not caught, and there is no risk of injury, making it possible to provide a safe and convenient automatic wallpaper gluer.

[0039] In addition, the automatic wallpaper pasting machine of the present invention comprises: the opening / closing control device comprises an arm member connected between the horizontal support frame and the leg frame, one connecting end of the arm member being rotatably connected to either the horizontal support frame or the leg frame, and an opening / closing biasing mechanism to which the other end of the arm member is connected, The opening / closing biasing mechanism includes the biasing member that biases the other end of the arm member to bias the leg frame in a direction to close relative to the horizontal support frame.

[0040] By configuring the arm member in this manner, one connecting end of the arm member is rotatably connected to either the horizontal support frame or the leg frame, and the other end of the arm member is connected to an opening / closing biasing mechanism.

[0041] The opening / closing biasing mechanism includes a biasing member that biases the other end of the arm member in a direction to close the leg frame relative to the horizontal support frame.

[0042] Therefore, the other end of the arm member is biased by the biasing member of the opening / closing biasing mechanism in a direction that biases the leg frame in a direction that closes the leg frame relative to the horizontal support frame.

[0043] Due to the biasing force of this biasing member which biases the leg frame in the closing direction relative to the horizontal support frame, even when the leg frame is unlocked from a locked closed state (closed legs state), the leg frame does not swing open 90 degrees due to its own weight in a pendulum motion, but slowly moves from the closed state (closed legs state) to the open state (open legs state).

[0044] This prevents the leg frame from suddenly changing from a closed state (closed leg state) to an open state (open leg state), and no strong impact occurs when opening, so the leg frame does not hit the feet, fingers are not caught, and there is no risk of injury, making it possible to provide a safe and convenient automatic wallpaper gluer.

[0045] In addition, the automatic wallpaper pasting machine of the present invention comprises: the opening / closing biasing mechanism includes an axial guide member along which the other end of the arm member is guided, The other end of the arm member is configured to be biased along the axial guide member by the biasing force of the biasing member in a direction to close the leg frame relative to the horizontal support frame.

[0046] With this configuration, the other end of the arm member is biased along the axial guide member by the biasing force of the biasing member in a direction that closes the leg frame relative to the horizontal support frame.

[0047] Therefore, the other end of the arm member is urged along the axial guide member by the urging force of the urging member in a direction that urges the other end of the arm member in a direction that closes the leg frame against the horizontal support frame.

[0048] The biasing force of this biasing member biases the leg frame in the closing direction relative to the horizontal support frame, so even when the leg frame is unlocked from a locked closed state (closed legs state), the leg frame does not swing open 90 degrees due to its own weight in a pendulum motion, but can slowly go from the closed state (closed legs state) to the open state (open legs state).

[0049] The automatic wallpaper pasting machine of the present invention is characterized in that the opening and closing control device is provided at least at one corner of the horizontal support frame.

[0050] In this way, it is desirable that the opening and closing control device be provided at least at one corner of the horizontal support frame.

[0051] The automatic wallpaper pasting machine of the present invention is characterized in that the opening and closing control device is provided inside either the horizontal support frame or the leg frame.

[0052] In this way, since the opening / closing control device is provided inside either the horizontal support frame or the leg frame, it does not get in the way when opening and closing the leg frame relative to the horizontal support frame between a closed state (closed leg state) and an open state (open leg state), and it is also convenient as it does not get in the way when transporting or applying wallpaper.

[0053] The automatic wallpaper pasting machine of the present invention is characterized in that the opening and closing control device is provided outside either the horizontal support frame or the leg frame.

[0054] In this way, the opening and closing control device may be provided outside either the horizontal support frame or the leg frame.

[0055] In this case, even if the opening and closing control device breaks down, parts can be easily replaced, which is convenient.

[0056] The automatic wallpaper pasting machine of the present invention is characterized in that the biasing force of the opening / closing control device is configured to be freely adjustable.

[0057] In this way, if the biasing force of the opening / closing control device is configured to be freely adjustable, for example, if the biasing force applied by the opening / closing control device to close the leg frame relative to the wallpaper pasting machine main body is large, the leg frame will stop halfway in the open position, and the worker will have to use their hands or other means to open the leg frame to the locked position in the fully open position (leg spread position).

[0058] In contrast, if the biasing force of the opening / closing control device is configured to be freely adjustable, the leg frame can be automatically opened to the locked position in the fully open state (leg spread state) and then locked, which is convenient.

[0059] In addition, the opening speed can be adjusted to be slow or fast depending on the operator's preference, which is convenient. [Effects of the Invention]

[0060] According to the present invention, an opening / closing control device is provided that controls the opening and closing of the leg frame relative to the wallpaper pasting machine main body, and the opening / closing control device is configured to urge the leg frame in a direction closing relative to the wallpaper pasting machine main body.

[0061] Therefore, even when the leg frame is unlocked from a locked closed state (closed leg state) due to the biasing force that biases the leg frame of this opening / closing control device in the closing direction relative to the wallpaper pasting machine body, the leg frame will not swing open 90 degrees due to its own weight in a pendulum motion, but will slowly move from the closed state (closed leg state) to the open state (open leg state).

[0062] This prevents the leg frame from suddenly changing from a closed state (closed leg state) to an open state (open leg state), and no strong impact occurs when opening, so the leg frame does not hit the feet, fingers are not caught, and there is no risk of injury, making it possible to provide a safe and convenient automatic wallpaper gluer.

[0066] 1 to 11, reference numeral 10 generally denotes an automatic wallpaper pasting machine of the present invention.

[0067] As shown in FIGS. 1 and 2, the automatic wallpaper gluing machine 10 includes a wallpaper gluing machine main body 12. The wallpaper gluing machine main body 12 includes a wall paper gluing machine main body 12, and a wall paper gluing machine main body 12. As shown in FIG.

[0068] The wallpaper pasting machine body 12 is provided with a roughly box-shaped body frame 14 that is open at the top so that the transport of the wallpaper being pasted can be seen.

[0069] Furthermore, a base frame 11 is provided below the main frame 14, and this base frame 11 has an approximately rectangular horizontal support frame 13 that supports the wallpaper pasting machine main body 12 (main frame 14), as shown in Figure 2.

[0070] A pair of leg frames 16 are provided below both ends of the left and right sides of the main frame 14, as indicated by arrow J in FIG. 1, and are attached to the horizontal support frame 13 so as to be openable and closable.

[0071] The base frame 11 and the wallpaper pasting machine main body 12 (main body frame 14) are arranged in a manner that allows for portability. In consideration of this, as shown in FIG. 2, the structure is such that it can be freely attached and detached by means of a fastening member 15 such as a so-called "snap lock."

[0072] 1, the main body frame 14 is composed of an upper frame 18 and a lower frame 20. The upper part of the upper frame 18 is provided with a pair of handles 18c spaced apart in the left-right direction.

[0073] By grasping and operating this handle 18c, as will be described later, wallpaper G can be placed on the wallpaper pasting machine main body 12, and for maintenance purposes, the machine can be opened and closed relative to the lower frame 20 as shown by arrow I in Figure 1, with a pivot axis (not shown) as the center of rotation.

[0074] Although not shown, the upper frame 18 and the lower frame 20 are provided with locking devices such as snap locks to secure the upper frame 18 in a closed position relative to the lower frame 20.

[0075] The upper frame 18 also has side plate portions 18a and 18b that form the left and right side portions.

[0076] On the other hand, as shown in FIG. 1, a lockable roller 24 is provided at the lower end of the leg frame 16, which allows the automatic wallpaper gluing machine 10 to be moved and positioned as desired.

[0077] 1, the lower frame 20 has side plates 20a, 20b that form left and right sides. One of the side plates 20a of the lower frame 20 has a drive unit 26 that incorporates a drive device such as a gear coupling mechanism, as well as a control device and drive motor for controlling the automatic wallpaper gluing machine 10.

[0078] 1, there is provided a display and operation panel unit 28 for displaying the measured wallpaper length (measurement result), controlling the drive motor, and inputting information such as the type of wallpaper G. The drive unit 26 is either detachably attached to one side plate 20a of the lower frame 20 or is fixed thereto.

[0079] Furthermore, as shown in Figures 1 and 2, the pair of leg frames 16 are provided with a wallpaper roll mounting stand 34 for rotatably and detachably mounting a wallpaper roll 32 around which wallpaper G is wound.

[0080] As shown in FIG. 2, the wallpaper G fed from the wallpaper roll 32 is fed to the upstream side of the lower frame 20.

[0081] Then, although not shown, by the gluing mechanism of the conventionally known wallpaper gluing machine main body 12, the wallpaper G sent out from the wallpaper roll 32 on the roll mounting stand 34 passes through the wallpaper gluing machine main body 12 of the automatic wallpaper gluing machine 10, and glue is applied to the back surface GB of the wallpaper G. The base fabric mounting stand 34 has a substantially triangular shape in side view in FIG. 1 and a substantially L-shape in FIG. 2, but the shapes are not particularly limited.

[0082] Then, as needed, the wallpaper G, with the anti-drying film B and cutting tape C attached to the adhesive surface of the back surface GB of the wallpaper G, can be wound up manually or automatically by a separate winding device not shown.

[0083] Alternatively, as shown by the dotted lines in Figure 1, the wallpaper receiving section 30 is an inclined, roughly plate-shaped section provided between a pair of leg frames 16, or is configured to be manually folded down below the wallpaper gluing machine main body 12 which receives glued wallpaper G discharged from the wallpaper discharge section 29 on the front side in Figure 1 and is placed directly on the floor.

[0084] Incidentally, when a dedicated automatic wallpaper pasting machine 10 is brought to a construction site and used to apply glue to the backside of wallpaper, when transporting the machine to the construction site, the fastening state using fastening members 15 such as so-called "snap locks" is released, and the base frame 11 and the wallpaper pasting machine main body 12 (main body frame 14) are loaded separately onto a truck or the like for transport.

[0085] Alternatively, after wallpaper application is completed at the installation site, the fastening state using the fastening member 15 such as the above-mentioned "snap lock" is released, and the base frame 11 and the wallpaper pasting machine main body 12 (main body frame 14) are transported separately from the site to the truck. When loading onto a truck, the base frame 11 and the wallpaper pasting machine main body 12 (main body frame 14) are fastened together with fastening members 15 such as the above-mentioned "snap lock," and then loaded onto a truck or the like for transportation.

[0086] At this time, the base frame 11 is in a state where the pair of leg frames 16 are closed (closed leg state) relative to the horizontal support frame 13 as shown by arrow J in FIG.

[0087] When the base frame 11 is unloaded from a truck or the like and transported to the construction site, the pair of leg frames 16 of the base frame 11 are in an open position (spread leg position) relative to the horizontal support frame 13, as shown by arrow J in Figure 1.

[0088] When the wallpaper pasting machine 10 is transported separately by loading it onto a truck or the like, the wallpaper pasting machine main body 12 (main body frame 14) is fixed onto the base frame 11 in a fastening state using fastening members such as so-called "snap locks," and the automatic wallpaper pasting machine 10 is assembled.

[0089] In this state, the automatic wallpaper pasting machine 10 is transported to the application site using the lockable rollers 24 provided at the lower ends of the leg frames 16.

[0090] In this case, similar to the configuration disclosed in Patent Document 1 (Patent Publication No. 4947629), the pair of leg frames 16 are configured to be securely locked to the horizontal support frame 13 in an open state (open leg state) and a closed state (closed leg state).

[0091] Specifically, as shown in Figs. 2 and 9 to 11, the front leg frame 16a and the rear leg frame 16b of the leg frame 16 are each provided with a leg frame lock control device 31 on the inside.

[0092] These leg frame lock control devices 31 are provided with a cylinder member 33, and a piston member 35 that is movable up and down is mounted inside the cylinder member 33 so as to be movable up and down.

[0093] As shown in Figure 2, an operating rod member 36 is fixed to the base end 37a of the piston rod 37 of this piston member 35 so as to bridge between the front leg frame 16a and the rear leg frame 16b.

[0094] On the other hand, inside the cylinder member 33, there is a gap between the expanded diameter portion 38 at the tip of the piston member 35 and A biasing member 40 such as a spring member is interposed in a compressed state.

[0095] As a result, the expanded diameter portion 38 at the tip of the piston member 35 is biased downward (toward the lower end of the leg frame 16). In addition, a first link member 48 of a lock link mechanism 46 is rotatably attached to the expanded diameter portion 38 at the tip of the piston member 35 by pivot shafts 42, 44.

[0096] In addition, an elongated hole 53 is formed above the first link member 48 of the lock link mechanism 46, and a support shaft member 52 formed at the lower end of the second link member 50 of the lock link mechanism 46 is attached so that it can slide within this elongated hole 53.

[0097] Furthermore, the upper ends of the second link members 50 of the lock link mechanisms 46 are rotatably attached to the horizontal support frame 13 via pivot shafts 51, respectively.

[0098] In addition, a stopper rod member 54 is fixed to each of the leg frames 16 (front leg frame 16a and rear leg frame 16b), and this stopper rod member 54 is engaged with a first stopper notch 56 formed in the first link member 48 of the lock link mechanism 46 and a second stopper notch 58 formed in the second link member 50 of the lock link mechanism 46, respectively, so that it can be securely locked in the open state (spread legs state) and the closed state (closed legs state).

[0099] That is, as shown in Figure 9, in the open state (legs spread state), the stopper rod member 54 fixed to the leg frame 16 is engaged in the first stopper notch 56 formed in the first link member 48 of the lock link mechanism 46, and is locked in the open state (legs spread state).

[0100] To change from this state to the closed state (leg-closed state), the operating rod member 36 is grasped by hand and moved upward against the biasing force of the biasing member 40.

[0101] As a result, the piston rod 37 connected to the operating rod member 36 and the enlarged diameter portion 38 at the tip of the piston member 35 move upward against the biasing force of the biasing member 40 .

[0102] This operation causes the first link member 48 and the second link member 50 of the lock link mechanism 46 to rotate, as shown by arrow D in Figure 10, and releases the engagement between the first stopper notch 56 formed in the first link member 48 and the stopper rod member 54 fixed to the leg frame 16.

[0103] At this time, as shown in Figures 9 and 10, the support shaft member 52 formed at the lower end of the second link member 50 of the lock link mechanism 46 moves from above to below within the elongated hole 53 of the first link member 48 of the lock link mechanism 46.

[0104] Then, as shown in Figures 10 and 11, the leg frame 16 is moved by hand or the like from the open state (leg-spread state) to the closed state (leg-closed state) as indicated by arrow E in Figures 10 and 11.

[0105] As shown in Figure 11, in the closed state (closed leg state), by releasing the operating rod member 36 held by hand, the piston rod 37 connected to the operating rod member 36 and the enlarged diameter portion 38 at the tip of the piston member 35 move downward due to the biasing force of the biasing member 40.

[0106] As a result, as shown by the arrow F in FIG. 11, the first link portion of the lock link mechanism 46 The member 48 and the second link member 50 rotate, and the second stopper notch 58 formed in the second link member 50 and the stopper rod member 54 fixed to the leg frame 16 are engaged with each other, and the legs are locked in the closed position (closed leg position).

[0107] Incidentally, as shown in FIG. 17, in the conventional automatic wallpaper gluing machine 200, when the leg frame 206 is unlocked from a state in which it is locked in a closed state (closed leg state) relative to the horizontal support frame, the leg frame 206 becomes free relative to the horizontal support frame.

[0108] As a result, the leg frame 206 swings open by 90 degrees due to a pendulum motion caused by its own weight. If the leg frame 206 suddenly swings from a closed state (closed legs state) to an open state (open legs state) in this way, a strong impact occurs when opening, which may hit the foot or trap a finger or other part, resulting in injury.

[0109] For this reason, the automatic wallpaper gluing machine 10 of the present invention is equipped with an opening / closing control device 100 that controls the opening and closing of the leg frame 16 relative to the wallpaper gluing machine main body 12 so that even when the leg frame 16 is unlocked from a state in which it is locked in a closed state (closed leg state), the leg frame 16 does not swing open 90 degrees due to its own weight in a pendulum motion, but rather slowly moves from the closed state (closed leg state) to the open state (open leg state).

[0110] The opening and closing control device 100 is configured to bias the leg frame 16 in a direction to close the wallpaper pasting machine body 12 .

[0111] Specifically, switching controller 100 has the configuration shown in FIGS.

[0112] That is, the opening and closing controller 100 constitutes an opening and closing controller 100 that controls the opening and closing of the leg frame 16 relative to the horizontal support frame 13. That is, the opening and closing controller 100 is configured to bias the leg frame 16 in a direction to close relative to the horizontal support frame 13.

[0113] As shown in Figures 3 to 8, the opening and closing control device 100 includes an arm member 102 connected between the horizontal support frame 13 and the leg frame 16. That is, in this embodiment, as shown in Figures 4 to 8, a fixed bracket 104 is fixed below the stopper rod member 54 of the leg frame 16.

[0114] One connecting end 108 of the arm member 102 is rotatably connected to the fixed bracket 104 via a pivot shaft 106 .

[0115] In this embodiment, the horizontal support frame 13 is provided with an opening / closing biasing mechanism 112 to which the other end 110 of the arm member 102 is connected.

[0116] This opening / closing biasing mechanism 112 has a slide shaft 114 fixed inside the horizontal support frame 13, which constitutes a guide member that guides the other end 110 of the arm member 102, which is fixed in place, in the horizontal direction. That is, as shown in FIG. 6, a slide shaft 114 is fixed between fixing flanges 101, 101 fixed to a horizontal support frame 13.

[0117] A slide member 117 rotatably connected to the other end 110 of the arm member 102 via a pivot shaft 116 is inserted into this slide shaft 114, and the slide member 117 is configured to be guided by the slide shaft 114 and move in the horizontal direction. .

[0118] In addition, a slide opening 115 is formed at the lower end of the horizontal support frame 13, and the other end 110 (slide member 117) of the arm member 102 is guided by the slide shaft 114 through this slide opening 115 so that it can move horizontally.

[0119] The slide shaft 114 is also provided with a biasing mechanism 118. This biasing mechanism 118 is configured to bias the other end 110 (slide member 117) of the arm member 102 in the direction of arrow H in FIGS. 3 to 8, thereby biasing the leg frame 16 in a direction closing relative to the horizontal support frame 13.

[0120] Specifically, in this embodiment, the biasing mechanism 118 is configured with a biasing member 120 disposed outside (on the left side of) the slide member 117 and interposed in a compressed state.

[0121] In this embodiment, the biasing member 120 is made up of a spring member that is mounted in a compressed state on the outer periphery of the slide shaft 114. This biases the other end 110 (slide member 117) of the arm member 102 in the direction of arrow H in Figures 4 to 8, thereby biasing the leg frame 16 in a direction closing relative to the horizontal support frame 13.

[0122] Although not shown, the slide member 117 may be configured with a biasing member arranged on the inside (right side) of the slide member 117 in Figures 3 to 8, and another biasing member arranged on the outside (left side) of the slide member 117 in Figures 3 to 8.

[0123] In this case, the biasing force (spring force) of the other outer biasing member is configured to be greater than the biasing force (spring force) of the inner biasing member, thereby biasing the other end 110 (slide member 117) of the arm member 102 in the direction of arrow H in Figures 4 to 8, and biasing the leg frame 16 in a direction closing relative to the horizontal support frame 13.

[0124] Furthermore, in this embodiment, the biasing mechanism 118 is arranged on the outside (left side) of the slide member 117 and is composed of a biasing member 120 interposed in a compressed state, but it can also be composed of a biasing member 120 arranged on the inside (right side) of the slide member 117 and interposed in a tensioned state.

[0125] In addition, in this embodiment, the biasing mechanism 118 uses a spring member, but it is also possible to use, for example, a rubber member, a hydraulic cylinder, a fluid pressure cylinder, a pneumatic cylinder, or other known biasing members.

[0126] In this embodiment, one connecting end 108 of the arm member 102 is connected to the leg frame 16, and an opening / closing biasing mechanism 112 that connects the other end 110 of the arm member 102 is formed inside the horizontal support frame 13.

[0127] However, although not shown, it is of course also possible to connect one connecting end 108 of the arm member 102 to the horizontal support frame 13 and form an opening / closing biasing mechanism 112 that connects the other end 110 of the arm member 102 inside the leg frame 16.

[0128] Furthermore, it is only necessary that opening and closing controller 100 is provided at least at one corner of horizontal support frame 13.

[0129] Furthermore, the biasing force of switching controller 100 may be configured to be freely adjustable.

[0130] In this way, if the biasing force of the opening / closing control device 100 is configured to be freely adjustable, for example, if the biasing force by the opening / closing control device 100 to bias the leg frame 16 in the direction of closing it relative to the wallpaper pasting machine main body 12 is large, the leg frame 16 will stop halfway in the open position, and the worker will need to use their hands or other means to open the leg frame 16 to the locked position in the fully open position (leg spread position).

[0131] In contrast, if the biasing force of the opening / closing control device 100 is configured to be freely adjustable, the leg frame 16 can be automatically opened to the lock position in the fully open state (leg spread state) and then locked, which is convenient.

[0132] In addition, the opening speed can be adjusted to be slow or fast depending on the operator's preference, which is convenient.

[0133] By configuring it in this manner, the automatic wallpaper pasting machine 10 of the present invention is equipped with an opening / closing control device 100 that controls the opening and closing of the leg frame 16 relative to the horizontal support frame 13, and the opening / closing control device 100 is configured to urge the leg frame 16 in a closing direction relative to the horizontal support frame 13.

[0134] Therefore, even when the leg frame 16 is unlocked from a locked state (closed legs state) due to the biasing force (biasing force of the biasing mechanism 118 of the opening / closing biasing mechanism 112) that biases the leg frame 16 of this opening / closing control device 100 in the closing direction relative to the horizontal support frame 13, the leg frame 16 does not swing open 90 degrees due to a pendulum motion due to its own weight, but slowly moves from the closed state (closed legs state) to the open state (open legs state).

[0135] As a result, the leg frame 16 does not suddenly change from a closed state (closed leg state) to an open state (open leg state), no strong impact occurs when opening, the leg frame 16 does not hit the feet, fingers are not caught, and there is no risk of injury, making it possible to provide a safe and convenient automatic wallpaper pasting machine. Example 2

[0136] Figure 12 is a schematic side view similar to Figure 2 of an automatic wallpaper pasting machine 10 of another embodiment of the present invention, Figure 13 is an enlarged partial view of Figure 12, Figure 14 is a view taken in the direction of arrow B in Figure 12, explaining the state in which the leg frame 16 is in an open state (open leg state) relative to the horizontal support frame 13 in the base frame 11, Figure 15 is a view taken in the direction of arrow B in Figure 12, explaining the state in which the leg frame 16 is in a closed state (closed leg state) relative to the horizontal support frame 13 in the base frame 11, and Figure 16 is a top view of Figure 14.

[0137] The automatic wallpaper pasting machine 10 of this embodiment has basically the same configuration as the automatic wallpaper pasting machine 10 shown in Figures 1 to 11, and the same components are given the same reference numbers and detailed descriptions thereof are omitted.

[0138] In the first embodiment described above, the horizontal support frame 13 is provided with the opening / closing biasing mechanism 112 of the opening / closing controller 100 to which the other end 110 of the arm member 102 is connected.

[0139] In contrast to this, in the automatic wallpaper pasting machine 10 of this embodiment, the opening / closing biasing mechanism 112 of the opening / closing control device 100 is provided outside the horizontal support frame 13.

[0140] That is, in the automatic wallpaper pasting machine 10 of this embodiment, the opening and closing biasing mechanism of the opening and closing control device 100 112 is provided on the inner side of the exterior of the horizontal support frame 13. The opening / closing biasing mechanism 112 of the opening / closing controller 100 may be provided anywhere outside the horizontal support frame 13, such as on the outer side, the upper outer side, or the lower outer side.

[0141] In this way, the opening / closing biasing mechanism 112 of the opening / closing controller 100 may be provided outside the horizontal support frame 13.

[0142] Moreover, similarly to the first embodiment, the opening / closing biasing mechanism 112 of the opening / closing controller 100 may be provided outside the leg frame 16.

[0143] By configuring it in this way, even if opening / closing controller 100 (opening / closing biasing mechanism 112) breaks down, parts can be easily and conveniently replaced.

[0144] The above has described a preferred embodiment of the present invention, but the present invention is not limited to this. In this embodiment, the base frame 11 is configured to include a substantially rectangular horizontal support frame 13 that supports the wallpaper pasting machine main body 12 (main body frame 14), and a pair of leg frames 16 that are attached to the horizontal support frame 13 in a manner that allows them to be opened and closed. However, various modifications are possible within the scope of the purpose of the present invention, such as the possibility of applying this to an automatic wallpaper pasting machine 10 of a type in which the horizontal support frame 13 is omitted and the pair of leg frames 16 are directly attached to the wallpaper pasting machine main body 12 (main body frame 14) in a manner that allows them to be opened and closed freely. [Industrial Applicability]
