Description

[Detailed description of the invention] This invention relates to a reel with a nail belt for a nail gun, and its purpose is to easily load a nail belt into a nail storage chamber formed in a magazine of a nail gun. The purpose of the present invention is to provide a reel with a belt.

An embodiment of this invention will be described below with reference to the drawings. In the figure, 1 is the nail gun main body, 2 is a driver having a nail driving path 3 through which a nail driver (not shown) is moved up and down. Guide 4 is a nail feeding casing in which a device for feeding nails into the nail driving path 3 is built-in. A magazine 5 attached across the nail feed casing 4 and one side of the nail gun main body 1 has a case main body 6 and a case main body 6.
The under cover 7 is attached to the opening at the lower end of the under cover so as to be openable and closable, and a nail storage chamber 8 is formed inside the under cover 7. In addition, a convex portion 9 protruding from the center of the inner surface of the upper wall of the case body 6
As shown in FIGS. 1 and 2, a pusher 11 biased downward by a spring 10 and a supporter 12 for regulating the downward movement range of the pusher 11 are attached to the pusher 11, respectively, as shown in FIGS. . On the other hand, a protrusion 13 having substantially the same diameter and the same center as the supporter 7 is formed in the center of the mounting surface 7a formed on the bottom surface of the undercover 7.

The nail belt attached reel 14 stored in the nail storage chamber 8 of the magazine 5 has a nail belt 20 and a reel 1.
It is mainly composed of 5. The reel 15 is formed to a size that can be stored in the nail storage chamber 8, and includes a cylindrical reel shaft 16 having a hole slightly larger in diameter than the supporter 12 and the protrusion 13 of the undercover 7.
The reel shaft 16 is mainly composed of upper and lower disks 17 and 18 fixed to the upper and lower end surfaces of the reel shaft 16 by flanged cylindrical fasteners 19, 19. In addition, the reel shaft 16 and both upper and lower disks 1
Reference numerals 7 and 18 are made of thick paper such as cardboard, and the cylindrical parts of the stoppers 19 and 19 are attached to the reel shaft 16, and the collar parts are glued to both the upper and lower disks 17 and 18, respectively. ing. Note that the reel shaft 16 and both the upper and lower disks 17, 18 may be integrally formed from a synthetic resin material.

The nail belt 20 wound around the reel shaft 16 of the reel 15 has a large number of nails 21 to 21.
are two flexible connecting tapes 22, 2, upper and lower.
2 are connected in parallel.
Furthermore, in order to securely connect and hold a large number of nails 21 to 21 at predetermined intervals, both the upper and lower connecting tapes 22, 22 are replaced with two adhesive tapes 2 on the front and back sides.
2a and 22b, and the adhesive surfaces of both adhesive tapes 22a and 22b are adhered to each other with nails 21 to 21 in between, as shown in FIG.

Note that the adhesive tape 2 constituting the connecting tape 22
2a and 22b are tapes made of a synthetic resin film such as polyester or thin paper, to which an adhesive is attached. And nail belt 20
is attached to the reel 1 by the holding tape 23 on one side.
It is connected to the reel shaft 16 of No. 5 and is wound sequentially along the outer periphery of the reel shaft 16.

The holding tape 23 has one side attached to the reel shaft 1.
6 and is attached to this reel shaft 16, and the other side is attached to several nails 21 on the core side of the nail belt 20. Furthermore, reel axis 1
The longest drawn length of the holding tape 23 for the magazine 5 is the same length as the distance from the center of the magazine 5 to the nail driving path 3, or is suitably longer.

The nail belt 20 is wound on the tip side of the nail belt 20 wound along the reel shaft 16 of the reel 15.
restraint tape 2 for restraining the reel 15
4 is pasted, and the tip of this restraining tape 24 is attached to some of the nails 21 of the nail belt 20 wound around the reel 15 on the side opposite to the nail 21 at the tip. It is pasted on the opposite side.

In the above configuration, the nail storage chamber 8 of the magazine 5
When loading the reel with nail belt 14 into the nail belt, remove the restraining tape 24 that restrains the tip of the nail belt 20, open the under cover 7 of the magazine 5, and fit the entire reel with nail belt into the nail storage chamber 8. After inserting, by closing the under cover 7,
A reel 14 with a nail belt is loaded into the magazine 5. At this time, the reel shaft 16 of the reel 15 is rotatably inserted into the supporter 12 and the protrusion 13 of the undercover 7, and the lower disk 18 is placed on the mounting surface 7a of the undercover 7 on the upper side. The disks 17 are abutted and supported by the pushers 11, respectively.

When the nail gun is operated with the nail belt 20 of the reel with nail belt 14 pulled out to a predetermined length and set on the nail feeding device built into the nail feeding casing 4, the nail belt 20 is located in the nail driving path. The nail 21 at the tip of the nail 20 is driven into the nailing surface by a nailing driver. At this time, the next nail 21 is inserted into the nail driving path 3 by the feeding device.
transferred within. After the nail belt 20 is sequentially pulled out from the reel 15 by the feeding action of the feeding device, and the nails 21 on the core end side of the nail belt 20 are pulled out from the reel shaft 16 of the reel 15,
The nail 21 on the core end side is held against the reel shaft 16 by a holding tape 23. That is, until the last nail 21 on the core end side of the nail belt 20 is sent out to the nail driving path 3, this nail 21 is connected and held by the holding tape 23, so that the nail 21 may fall down. It is possible to proactively prevent poor feeding and poor driving.

As exemplified above, this invention provides a nail gun with a magazine in which a nail storage chamber is formed.
A reel with a nail belt is formed by connecting a large number of nails with a thin and flexible connecting tape to form a nail belt, and winding the nail belt around a reel, the reel being a reel with a nail belt. A reel shaft having no winding core and rotatably fitted into the center of the magazine, and upper and lower disks facing each other at both ends of the reel shaft. Formed to a size that can be stored in a room,
Furthermore, among the nails of the nail belt, the nails on the core end side are connected to the reel shaft of the reel by a holding tape, and this holding tape is used to drive the nails from the reel shaft to the nail gun. This is a reel with a nail belt for a nail gun, characterized by having a length up to the length of the nail belt.

Therefore, according to this invention, when loading a nail belt into the nail storage chamber of a magazine in a nail gun, it is possible to eliminate the trouble of loading the nail belt while winding it around the nail storage chamber each time. Since it is only necessary to load reel nails made by winding a nail belt around a reel, the loading work can be easily and quickly carried out.

Moreover, the tips (lower ends) of many nails in the nail belt are supported by the lower disk of the reel,
The head (upper end) of the nail can be supported by the upper disk. For this reason, a nail belt consisting of a large number of nails connected by a thin and highly flexible connecting tape can be stably wound and held in a spiral shape, and can be wound tightly. This has the effect that more nails can be set in the magazine.

Further, according to this invention, the nails on the core end side of the nail belt are connected to the reel shaft of the reel by means of a holding tape, and the holding tape is connected to the nails from the reel shaft to the nails. Since the length is up to the nail driving path in the machine, the last nail on the core end side of the nail belt is connected by the holding tape until it is sent out to the nail driving path. Since the nail can be held, it is possible to prevent the nail from collapsing, thereby preventing poor nail feeding and poor driving.
