Description

  The present invention relates to a wallpaper pasting machine, and more particularly to an attachment structure between a wallpaper pasting machine and a slitter.

  FIG. 5 is a side perspective view showing the overall configuration of a conventional automatic wallpaper pasting machine. As shown in FIG. 5, the automatic wallpaper pasting machine 51 includes a lower structure 52 in which a glue basket 54 for storing glue is installed, an upper structure 53 installed to be openable and closable with respect to the lower structure 52, It is mainly comprised from the leg part 531 which supports the structure 52. FIG.

  In the lower structure 52, a sheet-like wall covering material (hereinafter referred to as “cross”) C is drawn into the gluing machine main body 51 from the rear surface side, sent to the gluing roll 58, and taken in and taken in. A glue raising roll 513 for transferring the glue in the basket 54 to the glue roll 58, a glue roll 58 for applying glue on the back of the cloth, a doctor roll 57 for adjusting the glue amount in contact with the glue roll 58, A leveling roll 59 that applies an appropriate tension to the cloth C and feeds it forward is arranged in parallel with the side plate of the glue pad 54 so as to be interlocked with each other via a gear and in parallel with a predetermined interval. Is supported by a simple bearing plate.

  On the other hand, in the upper structure 53, the upper pinch roll 510 that forms a pinch roll paired with the feed roll 56 and the roll and gear arranged in the lower structure 52 are linked to each other and glued to the cross C. A drive roll 512 for applying a feed tension toward the front of the machine body and a press stay 511 for pressing the cross C from above between the upper pinch roll 510 and the drive roll 512 are parallel to each other at a predetermined interval. As arranged, each is pivotally supported by the main body side bearing frames of the upper structure 53.

  Further, a pair of legs 531 that support both side edges of the lower structure 52 are crossed from a raw roll 540 that is passed through the central axis of a cross core rod 541 supported at the tip of the cross receiving bracket 542. A first tension bar 532 which is in contact with C and applies a pulling load at the pulling port of the pasting machine main body is bridged. Above that, a second tension bar 533 is also bridged, which similarly contacts the cross C and applies a pulling load at the pulling port.

  A slitter 61 including an overcutter (upper blade) 62 and an undercutter (lower blade) 63 for cutting both side edges of the cloth is detachably attached to the rear surface side of the lower structure 52. The slitter 61 hooks the fixing hook 64 of the slitter 61 on the rear surface stay 60 on the rear surface side of the feed roll 56 of the lower structure 52, and the inner surfaces of both bearing plates of the lower structure and the inner surface of the bearing plate of the slitter 61 are flush with each other. It is fixed by a stopper 65 and a latch (so-called snap lock) 66 provided on the side surface.

  The gluing machine main body 51 and the slitter 61 need to be fixed securely because the driving source of the undercutter 63 of the slitter 61 is obtained by the gears from the driving of the gluing roll and other rolls. . If the clasp 65 and the snap lock 66 are not sufficiently fixed, the slitter 61 will be lifted upward, and the cutting point of the wallpaper will not be constant, so that clean cutting will not be performed.

  However, fixing with a clasp and a snap lock is extremely troublesome for an operator, and a structure that can be firmly attached by a simple operation has been desired. In such a demand, an attachment / detachment structure using an elastic locking body that can be engaged with the pin body by being deformed rather than being fixed by a clasp and a snap lock has already been proposed (for example, see Patent Document 1). .

JP 09-150084 A

  However, since the previous proposal is locked to the pin body by deformation of the elastic locking body, it is removed by vibration during cutting and gluing work and deterioration of the resilience of the elastic locking body due to long-term use. In addition, problems such as loosening and looseness may occur due to long-term use.

  The present invention allows the slitter to be securely attached to the main body of the wallpaper pasting machine by simple operation, as well as the wallpaper paste that can be securely fixed even by vibration during cutting and pasting operations and long-term use. The purpose is to obtain an attached machine.

The wallpaper pasting machine according to the invention described in claim 1 is a slitter that continuously cuts both edges of a sheet-like wall covering drawn from a raw roll, and both edges cut by the slitter. In a wallpaper gluing machine including a gluing machine body that continuously applies glue to the back of a wall covering,
A first latching mechanism and a second latching mechanism for detachably attaching the slitter to the gluing machine main body are provided at different height positions between the slitter and the gluing machine main body,
The first latching mechanism is located above the second latching mechanism;
At least one of the first latching mechanism and the second latching mechanism is provided with a pressing means for pressing the slitter against the gluing machine body ,
As the pressing means,
In addition to the weight of the slitter, a push-down mechanism that applies a force in a direction to push down the slitter relative to the gluing machine body to the first latching mechanism;
A contact transmission mechanism that provides the second latching mechanism with a force for pressing the slitter against the gluing machine body based on the action of the force by the pressing mechanism;
As the contact transmission mechanism,
A hook-like member of a contact transmission mechanism fixed to one of the slitter or the gluing machine main body, and an engagement piece of the contact transmission mechanism fixed to the other of the slitter or the gluing machine main body facing the hook-like member. Including
The edge or surface where the hook-shaped member is in sliding contact with the engagement piece includes a taper that is a force that presses the slitter against the gluing machine main body based on the action of the self-weight or the force of the push-down mechanism,
The hooking piece is fixed to the slitter or the gluing machine body through a leaf spring mechanism that applies a force for pressing the slitter against the gluing machine body .

With wallpaper glue machine according to the invention described in claim 2, the continuous pasting machine body according to claim 1, and an upper structure which is opened when mounting the wall covering, the rear surface of the wall covering Including a lower structure including a gluing roll for applying a paste,
On the upper surface of the lower structure, a hook piece for a first hooking mechanism on which a hook material for the first hooking mechanism fixed to the slitter is hooked is provided.
Wherein a depressed mechanism, provided with a projecting piece provided on the upper structure so as to face the engaging portion of the lock plate for the first latching mechanism hook material for the first latching mechanism is latched It is what.

  As described above, according to the present invention, the slitter can be securely attached to the main body of the wallpaper pasting machine by a simple operation, and can be securely fixed even by vibration during cutting and pasting work and by long-term use. There is an effect that can be done.

  In the present invention, the first latching mechanism and the second latching mechanism for detachably mounting the slitter to the gluing machine main body are provided between the slitter and the gluing machine main body at different height positions. At least one of the first latching mechanism and the second latching mechanism is provided with pressing means for pressing the slitter against the gluing machine body. For this reason, the first latching mechanism and the second latching mechanism are latched at two different positions, and the slitter is prevented from being lifted by the pressing means, so that the slitter can be easily attached to the wallpaper pasting machine body. Installed securely in operation.

  The wallpaper pasting machine in the present invention refers to a wallpaper pasting machine equipped with a slitter. In addition to automatic wallpaper gluing machines equipped with a drive source such as a prime mover when gluing, manual gluing machines that manually pull out wall coverings if the slitter itself has a drive source that drives a rotary blade. In addition, since the present invention is applicable, it also refers to a manual wallpaper pasting machine.

  Moreover, as a press means in this invention, what is necessary is just to press a slitter against the gluing machine main body. For example, a preferred embodiment of the present invention includes a contact transmission mechanism that generates a force for pressing the slitter against the gluing machine body based on its own weight. As another aspect, when the first hooking mechanism is positioned above the second hooking mechanism, the slitter is relatively positioned with respect to the gluing machine body in addition to the weight of the slitter. A push-down mechanism that applies a force in the push-down direction to the first latching mechanism; and a contact transmission mechanism that applies a force to push the slitter against the gluing machine body based on the action of the force by the push-down mechanism. Things.

  Furthermore, as the contact electric mechanism in the present invention, any force may be used as long as the slitter is pressed against the pasting machine body by a downward force. For example, as a preferable embodiment, a hook-like member of a contact transmission mechanism fixed to one of a slitter or a gluing machine main body, and a contact transmission mechanism fixed to the other of the slitter or the gluing machine main body facing the hook-like member. The edge or surface where the hook-shaped member is in sliding contact with the engaging piece includes a taper that makes the slitter force to press against the main body of the gluing machine based on the action of the force by the own weight or the push-down mechanism. It is done. Thereby, a fixed state can be maintained even by vibration during cutting and gluing operations and long-term use.

  In addition, the hook-shaped member and the engaging piece can be installed on either the gluing machine main body or the slitter as long as the pair of the hook-shaped member and the hooking piece faces each other. For example, when a hook-like member is installed on the slitter, the claw part of the hook-like member is installed downward, and when installed on the gluing machine body, the claw part is installed upward. The

  Moreover, as a pressing-down mechanism in this invention, what is necessary is just to provide the force of the direction which presses down a slitter relatively with respect to a pasting machine main body. This prevents the slitter from being lifted during the cutting operation even in the slitter that is driven from the gluing machine body. That is, the slitter rotates the rotary blade when the driving force is transmitted from the gluing machine main body through the gear, and cuts both ear portions of the wall covering. For this reason, since the fixing is insufficient only by the weight of the slitter alone, the slitter is lifted upward, and as a result, the cutting point of the wallpaper is not constant, and a beautiful cutting may not be performed.

  As a more specific depressing mechanism, the gluing machine body includes an upper structure that is opened when the wall covering material is mounted, and a lower structure that includes a gluing roll that continuously applies glue to the back surface of the wall covering material. As a preferred embodiment, the upper surface of the lower structure is provided with a first latching mechanism hooking piece for hooking the first hooking mechanism hook material fixed to the slitter. The thing provided with the protrusion piece provided in the upper structure facing the hooking part of the hook piece for 1st latching mechanisms on which the hook material for 1st latching mechanisms was latched.

  As the engagement piece of the contact transmission mechanism in the present invention, it slides against the edge or surface of the hook-like member having a taper and presses the slitter against the gluing machine main body based on the action of the weight of the slitter or the force of the push-down mechanism. Any force can be used as long as it generates a force, such as a pin.

  As a preferable aspect of the engagement piece for the contact transmission mechanism, one fixed to the slitter or the pasting machine main body through a leaf spring mechanism can be cited. For example, what hold | maintains on the one end of the leaf | plate spring which bent the pin as said latching piece, and fixes an other end part to a gluing machine main body or a slitter is mentioned. Thereby, a more reliable fixed state can be maintained even by vibration during cutting and gluing operations and long-term use. That is, the taper of the hook-like member arranged on the slitter or the gluing machine main body and the pin are brought into sliding contact, the pin is pulled by the weight of the slitter, and the direction of the gluing machine main body or the slitter in which the leaf spring is fixed to the pin Since the urging force for urging is applied, a more reliable fixed state can be maintained even by vibration during cutting and gluing operations and long-term use.
