Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stapling apparatus for stapling a decorative plywood to a core material in a process of manufacturing a wrapping material used in the interior of a prefabricated house or the like. About. [0002] As interior materials for prefabricated houses and the like,
A wrapping material 1 as shown in FIG. 2 is used. This wrapping material 1 is obtained by covering a core material 11 having a cross section of about several centimeters square with a decorative plywood 12 having a thickness of about several millimeters.
Of the decorative plywood 12 and fixed to the core 11 by stapling both edges of the decorative plywood 12 with a tucker (also referred to as “stapler” or “Neila”). . [0003] A needle driving device 2 used in the manufacturing process of the wrapping material 1 is illustrated in Figs. Heartwood 11
Wrapping material 1 with decorative plywood 12 folded over
The face on which both edges of the decorative plywood 12 are overlapped, that is, the face to be stapled, faces upward, and is transported on the roller conveyor 3 along the longitudinal direction. Above the transport path, two stationary tuckers 4 are mounted with their positions slightly shifted back and forth in the transport direction. The respective tuckers 4 are mounted symmetrically in the transport direction, and the contact heads 41 of the respective tuckers 4 are located immediately above the left and right edges of the decorative plywood 12, respectively. And these contact heads 4
A substantially U-shaped needle 42 that is driven downward from 1
(It is also called "staple" or "nail.")
However, each edge of the decorative plywood 12 is sequentially fixed to the core material 11 along the transport direction. A plurality of guide rollers 5 are attached to the side of the roller conveyor 3 at appropriate intervals in order to bring the decorative plywood 12 and the core material 11 into close contact with each other at the time of stapling. The guide roller 5 is a roller having a cylindrical surface having a height slightly higher than the thickness of the wrapping material 1, and is arranged so as to press both side surfaces of the wrapping material 1 in a state where the rotation axis is upright. Further, the contact head 4 of each tucker 4
A pair of front and rear pressing rollers 6 are attached to 1 in order to press the vicinity of the stapling point of the decorative plywood 12 from above. The pressing roller 6 is mounted on the tucker 4 via a roller mounting plate 61 made of a steel plate or the like with the rotation axis being horizontal. [0006] The tucker 4 in the needle driving device 2 has a magazine 43 extending laterally in the transport direction, and a continuous driving needle 42 loaded in the magazine 43 is provided. One by one is sent to the contact head 41. A detachable head cover 44 is attached to the side surface of the contact head 41 so that the needle 42 jammed in the contact head 41 can be removed when the needle jam occurs. However, in the needle driving device 2 configured as described above, since the roller mounting plate 61 for supporting the pressing roller 6 is mounted so as to cover the contact head 41 of the tucker 4, the needle clogging is performed. In this case, the roller mounting plate 61 hinders the head cover 44 from being detached. Therefore, conventionally, each time the needle is clogged, the tucker 4 is detached from the mounting frame 21 and the contact head 41 is disassembled and repaired. The work of attaching and detaching the tucker 4
The operation has to be performed in a cramped space surrounded by an outer frame (not shown) of the needle driving device 2 and the like, and the operation is troublesome and requires a long time. The present invention has been made in order to solve such inconvenience. The contact cover 41 can be opened and closed by opening and closing the head cover 44 without removing and attaching the tucker 4 when the needle is clogged.
It is an object of the present invention to provide a lapping material stapling apparatus that can perform disassembly and repair of a wrapping material. [0009] In order to solve the above-mentioned problems, the present invention relates to a lapping material stapling apparatus, comprising: a conveyor for conveying a wrapping material in which a core material is covered with decorative plywood along a longitudinal direction; A tucker that is arranged above the conveyance path of the wrapping material and performs stapling on the wrapping material,
In a lapping material needle driving device including a pair of front and rear pressing rollers that press the wrapping material from above in the vicinity of the tucker, the pressing roller is supported via a roller mounting plate attached to the tucker, The roller mounting plate is formed in an arch shape which does not interfere with opening and closing of a head cover mounted on a contact head of the tucker. According to the present invention, the roller mounting plate is formed in an arch shape so as not to interfere with the opening and closing of the head cover. The needle can be removed. This allows
Loss time in the manufacturing process of the wrapping material can be shortened and the working efficiency can be increased. Embodiments of the present invention will be described below with reference to the drawings. However, the overall configuration of the lapping material stapling apparatus of the present invention is substantially the same as that of the conventional stapling apparatus 2 shown in FIGS. 3 to 5, and thus only the essential parts of the new configuration will be described. Further, among the parts and members constituting the lapping material stapling apparatus of the present invention, the parts and members that are functionally common to the conventional stapling apparatus 2 have the same names and symbols as those described above. FIG. 1 is a view of a portion of the tucker 4 which is a main part of the present invention in the vicinity of the contact head 41 as viewed from the side in the transport direction. As shown in FIG. 4, two tuckers 4 are mounted symmetrically with their positions slightly shifted back and forth in the transport direction as shown in FIG. 4, but only one is shown in FIG. 1 for convenience. As is apparent from FIG. 1, in the lapping material needle driving device 20 of the present invention, the pressing roller 6 is provided.
Is formed in an arch shape when viewed from the side. The arch shape is not necessarily limited to the illustrated form, and the leg portions 6 support the front and rear pressing rollers 6 respectively.
01 may be provided apart from each other, and the base 602 connecting these legs 601 may be attached at least at a position higher than the contact head 41 of the tucker 4. When the roller mounting plate 60 is formed in this manner, the contact head 41 of the tucker 4 is opened to the side, and the head cover 44 mounted on the contact head 41 becomes the roller mounting plate 60.
1 can be easily attached and detached without interference. This allows
Even if the tucker 4 is not removed at the time of needle clogging, it is possible to easily remove only the head cover 44 and remove the clogged needle 42, thereby reducing the loss time in the manufacturing process of the wrapping material 1 and increasing the working efficiency. In the present invention, the detailed internal structure of the tucker 4 and the stapling interval are not particularly limited. Further, as a means for transporting the wrapping material 1, a conveyor having a structure other than the roller conveyor 3 may be employed. Further, the arrangement interval and the support structure of the guide rollers 5 are not limited to the illustrated embodiment, but can be appropriately changed. The lapping material stapling apparatus of the present invention comprises:
Since the roller mounting plate is formed in an arch shape so as not to interfere with opening and closing of the head cover, it is possible to easily remove only the head cover and remove the clogged needle without removing the tucker when clogging the needle. Thereby, the loss time in the manufacturing process of the wrapping material can be shortened, and the working efficiency can be increased. In addition, since only the head cover of the tucker needs to be attached / detached, wear points such as bolts and nuts generated at the time of attachment / detachment can be limited.
