A, A ': Nailing Machine

The present invention relates to a crucible machine for a wooden box for storing fish and the like.

The conventional nailing machine which drives the required number of nails from the side plate to the end plate at the same time and forms the box side half border (half of the box side border) or the box side edge, in the case of the above box side half edge, raises the end plate on the table, The side of one side of the side plate is superimposed on the upper side of the raised end plate.In the case of the side edge of the box, the side plate of the side edge of the box is placed on the table, and the end of the side plate forming the side edge of the box on the top side of the end plate. Nest the back.

In this way, when the pedal of the nailing machine is pressed, each hammer shaft descends, the atmospheric nail in the nozzle descends, and the nail is driven from the side plate to the end plate.

In addition, the nailing machine that nails the bottom plate to the box side border is placed by placing the box side border on the table and pressing the rear end plate of the box side border placed on the bottom stopper on the table to determine the position.

Subsequently, the bottom plates are arranged side by side on the edge of the box, while the end faces of the bottom plates are opposed to the top stopper on the table to prevent the edges of the bottom plates from blowing out on the surface of the end plates.

After that, nails are nailed to the end plate from the bottom plate as described above.

If the end edge of the end plate is not cut at right angles to the side edge of the end plate, the descent length of each parallel hammer axis is constant, so on the inclined high side, the end of the hammer axis with the nail head on the side plate is greatly There was a problem of digging into the sidewalls, and on the inclined low side, the nail heads were left (protruding) right next to the surface of the sideboard.

In addition, when the edge of the bottom plate is cut at an angle, even if the surface of one end and the end plate can be roughly one sided by the top stopper, the edges of the bottom plate of the remaining one end edge are blown out. The end plate cannot be pressed against the lower stopper by contact with the upper stopper.

For this reason, nails cannot be nailed to the center of the plank thickness of the end plate.

Then, the subject of this invention is to provide the nailing machine which prevented the splitting of the side board and the protruding nail head, and nailed in the center of the plate thickness of the end board.

In order to solve the above problems, the present invention adopts a configuration in which a supporting sheet portion which is capable of descending by tilting and moving against an upward return force is formed in accordance with an overload on the end plate end support portion of a table in a nailing machine.

Moreover, in the nailing machine which provided the fixed bottom end stopper for bottom plate and the top end stopper for bottom plate on a table, the said upper end stopper is slidably installed in the front-back direction, and the lower end stopper The configuration that gives the return force to the same level of is adopted.

When nailing the end plate from the side plate, if the side plate is inclined by the inclined cutting of the end edge of the end plate, the end of the hammer shaft first on the inclined high side of the side plate on the end edge of the end plate, and then on the inclined low side The ends of the hammer shafts sequentially contact each other, and the overload is applied to the inclined high side, so that one side of the end plate is pushed down.

In accordance with the above pressing, one side of the supporting sheet portion is pressed down against the rising return force, and the upper surface of the supporting sheet portion which moves inclined according to the pressing down is modified to be parallel to the inclination of the edge of the end plate. The upper surface is parallel to the upper surface of the table.

For this reason, the head of each nail is dug in the side board uniformly, and the crack of the side board and the protruding of the nail head are eliminated.

In addition, when the end plate is stopped in position by pressing the surface of the end plate against the lower stopper, even if the end edge of the inclined cutting of the bottom plate protrudes from the surface of the end plate, the top stopper is pushed back by the protruding end edge and lowered. Since the stopper is in contact with the end plate, the nail is driven from the bottom plate to the center of the plate thickness (two equal positions).

EMBODIMENT OF THE INVENTION Hereinafter, the Example which concerns on this invention is described based on an accompanying drawing.

(First embodiment)

As shown in FIG. 1 and FIG. 2, the end plate 1 and the side plate 2 of the table 11 in the nailing machine A of the end plate 1 of the end plate 1 of the table 11 are raised in accordance with the overload. A support sheet portion 12 is provided which is capable of descending while being inclined against the return force.

The supporting sheet portion 12 is a recessed cut-out portion 13 in which the upper surface formed on the table 11 is opened, and a metal supporting plate fitted into the recessed cut-out portion 13 in the case shown. (14), the rubber plate (15) is configured to consist of a rubber plate (15) fixed to the lower surface of the support plate (14) by a screw or the like, and to compress the rubber plate (15) by an overload acting on the support plate (14). Instead, a method of arranging coil springs may be employed.

In the above-described configuration, as shown in FIG. 3, one end portion of the side plate 2 is first raised on the support sheet portion 12 and then raised, and then the upper end surface of the raised end plate 1 is raised. Nest the back.

Next, by stepping on the pedal (not shown) of the nailing machine A and lowering each of the parallel hammer shafts 3 (two in the case of illustration), the nail box 4 passes through the hose 5 and the nozzles ( The nail 7 supplied in 6) descends by the falling hammer shaft 3 and is driven from the side plate 2 to the end plate 1 at the same time.

However, when the edge of the end plate 1 is not cut at right angles to the side edge of the end plate 1, the side plate 2 on the end plate 1 is inclined due to the inclined cutting, so that the inclined high One edge of the end plate 1 is pushed down by the hammer shaft 3 which contacts the side first.

In accordance with the pressing down, the one end of the supporting sheet portion 12 is pushed down against the rising return force while the supporting seat portion 12 is inclined to move as shown in FIG. The upper surface of the side plate 2 is corrected to be parallel to the upper surface as shown in FIG.

For this reason, the head of the nail 7 is uniformly driven in the side plate 2, and the splitting of the side plate 2 and the protruding head of the nail 7 are eliminated.

In addition, in the nailing machine A, a box side border is nailed using two box side borders as in FIG. 5, a solid line and a line border and a dashed line in FIG.

In the figure, reference numeral 16 denotes a positioning stopper between the end plate 1 and the side plate 2.

Second Embodiment

As shown in FIGS. 6 and 7, a plurality of bottom plates 22 are arranged on the box side borders 21 formed by nailing two box side borders, and the end plates are separated from the bottom plate 22. On the table 11 of the nailing machine A 'which nails in (1), the stationary lower stopper 23 which contacts the surface of the said end board 1 so that the end board 1 may be stopped in an exact position, An upper end stopper 24 for the bottom plate 22 which is slidable in the front-rear direction and which gives a return force to the same level as the lower end stopper 23 is provided.

As shown in FIG. 8 and FIG. 9, the lower end stopper 23 is fixed to the nozzle 6 via the clamp 30 through the arm 25 protruding downward, and the upper end The stopper 24 slidably penetrates the protruding shaft 27 protruding rearward from both ends of the upper arm 25 in the transmission hole 26 of the arm 25 and at the end of the protruding shaft 27. The stopper member 28 fixed to the arm 25 is brought into contact with the rear surface of the arm 25 to stop the surface of the upper stopper 24 at the same level as the surface of the lower stopper 23, and is fitted to the outside of the protruding shaft 27. Both ends of the coil spring 29 are brought into contact with the upper end stopper 24 and the arm 25 to impart a return force to the upper end stopper 24.

With the above construction, the box side border 21 is placed on the table 11, the bottom stopper 23 is pressed against the surface of the end plate 1, and the bottom is arranged on the box side border 21. When the end of the plate 22 is not nailed to the end plate 1, the end edge of the bottom plate 22 protrudes toward the surface of the end plate 1 according to the oblique cutting of the end of the bottom plate 22. If there is, the upper stopper 24 which fits the edge of the bottom plate 2 is pushed back to maintain the contact state of the lower stopper 23 and the surface of the end plate 1.
