The nail discharging mechanisms 53A and 53B are arranged so as to be connected to the nail receiving portions of the nailing heads NA and NB when located at the right end.

Next, the mechanism of the nailing head will be described with reference to FIG. Since the nailing heads NA and NB provided in the nailer trucks 6A and 6B have substantially the same mechanism, the description of the nailing head NB will be omitted.

The nailing head NA has a nailing portion 21 and a nail storage portion 22 for storing a predetermined number (for example, 60) of nails. The nail storage unit 22 supports a mechanism similar to the nail discharging mechanism 53A, that is, supports the head of the received nail, and easily receives the nail supplied from the nail discharging mechanism 53A and maintains the aligned state. It is composed of two inclined plates that sandwich the part. Vibration is applied to the two plates by a vibration source incorporated in the nailing head NA, so that the nails are reliably transported by their own weight. The plates of the nail storage portion 22 and the nail discharging mechanisms 53A and 53B have substantially the same inclination angle, and form a continuous transport path. In this way, the nail can be transported only by the weight of the nail and the vibration of the plate without providing a drive device. A nail full detection sensor 22 such as a proximity switch for detecting the nail fullness is provided at the entrance side of the nail storage portion 22.
A is provided, and an empty nail detection sensor 22B such as a proximity switch that detects an empty state of the nail is provided on the nailing portion 21 side. When the nail full detection sensor 22A detects that the nail is full, the nail discharge is stopped by the stopper arranged at the tip of the nail discharge mechanism 53A. Further, when the empty nail detection sensor 22B detects that the nails are exhausted during nailing, the nailing head NA returns to the origin position and receives the supply of nails.

The nail striking portion 21 receives the nails cut out from the nail storage portion 22 one by one, and strikes the nails received by the built-in striker. Nailing head NA
The (nail driving part 21 and the nail storing part 22) is a cylinder 32.
(Refer to FIG. 6), the nail storage part 22 becomes the nail discharge mechanism 53A.
The height position can be switched between an ascending position where the nail can be received from the ascending position and a descending position where the nail is hit. A head guide member 23, which is in contact with the face material 2 in the lowered position, is provided below the nail driving portion 21.
The head guide member 23 is bowl-shaped and reliably guides the head along the upper surface of the panel. The head guide member 23 is provided at a position slightly lower than the upper surface of the face material 2.
If the head height is set so that the lower end of the head is positioned and the nailing head NA is moved onto the face material 2 in this state, the head guide member 23 can be surely brought into contact with the face material 2,
It is possible to always keep the distance between the nailing head NA and the face material 2 constant. On both the left and right sides of the head guide member 23, the face material 2
A face material detection sensor 23A for detecting the presence / absence of the existence of the The reason why the nailing head NA is located at the raised position is originally to prevent the panel from colliding when the panel is carried onto the surface plate 4 and positioned at the fixed point O.

The nail driving section 21 is provided with a nail cutting section 24 for cutting out the nails aligned in the nail storage section 22 one by one. The nail cutout 24 is shown in FIG. FIG.
It is the figure which planarly viewed the nailing part 21 and the nail storage part 22.
The nail cutout portion 24 has a substantially cylindrical shape and is rotatable about a vertical axis. The nail cutout portion 24 has one end fixed to a side surface of the rotating member 25 and the other end having a rotation driving source of the rotating member 25. And a lever member 26 for pivoting the pivot member 25, which is pivotally attached to the rod 27A of the cylinder 27. A groove 25 </ b> A for holding the body portion of one nail is formed in the vertical direction on the side portion of the rotating member 25.

A bracket 28, which supports the rotating shaft, is fixed to the frame above the rotating member 25.
A striker portion 29, which is a striker passing position, is provided at a position where the groove 25A of the rotating member 25 is rotated by 90 ° from the state where the groove 25A is continuous with the nail storage portion 22. The striker portion 29 is a passage hole having a diameter slightly larger than the diameter of the nail head. The bracket 28 not only supports the rotating shaft, but also holds in the groove 25A of the rotating member 25 by protruding in the moving path of the nail held in the groove 25A of the rotating member 25 in the vicinity of the striker portion 29. It also guides the nails that have been made to the striker portion 29. The nail cutting portion 24 cuts nails one by one by the following operations. First, when the lever member 26 is pushed by the cylinder 27, the groove 25A of the rotating member 25 is in a state of being continuous with the outlet of the nail storage portion 22. In this state, the body of one nail fits into the groove 25A and holds this nail.
Next, when the lever member 26 is pulled by the cylinder 27, the rotating member 25 is rotated 90 ° toward the striker portion 29, and the groove 25A holding the nail is continuous with the striker portion 29. At this time, the head of the nail hits the bracket 28,
It is pushed out to the striker unit 29. By repeating this operation, the nails can be supplied to the striker portion 29 one by one.

The striker section 29, as shown in FIG.
It has a nail holding mechanism for temporarily holding the nail received from the rotating member 25, and a striker for striking the held nail. The nail holding mechanism receives the nail tip portion when the nail from the rotating member 25 falls into the passage hole extending in the vertical direction of the striker portion 29, and holds a pair of left and right nail holding portions which can be freely opened and closed around the fulcrum 11A. It is composed of a member 11 and a spring 12 for urging the nail holding member 11 in a closing direction. Inside the nail holding member 11, there is formed a tapered groove 11B that becomes thinner as it goes downward so that the nail holding member 11 gradually expands by the nail that descends during nailing. The urging force of the spring 12 is set such that the nail holding member 11 does not open under the load of the falling nail, and the nail holding member 11 opens with the force when the nail is driven below the head by the force of the striker. There is.

The nailing head NA has a head swinging mechanism 30 in addition to these. That is, when attaching one face member 2 to one frame member, it is sufficient to drive a nail in the vertical direction at the center of the frame member, but two face members 2 are attached to one frame member.
In the case where the edges are attached so that the edges are adjacent to each other, it is necessary to incline the nails from a position displaced from the center (joint) of the frame material toward the center of the frame material. (Hereinafter, referred to as inclined driving.) Specifically, as shown in FIG. 10, the nailing head NA can be raised and lowered by the cylinder 32 (FIG. 6) and can be swung by the cylinder 31. There is.
Bracket 33 fixed to the rod end of cylinder 32
Two rollers 33A are fixed to (FIG. 6). The cylinder 31 is pivotally attached at a fulcrum 33B provided on the bracket 33, and the rod tip of the cylinder 31 is pivotally attached at a fulcrum 31A above the nailing head NA. Also,
An arcuate groove N1 with which the roller 33A is engaged is formed in the nailing head NA. Therefore, as the cylinder 31 moves back and forth, the nailing head NA has the groove N1 and the roller 33A.
Since the groove N1 has an arcuate shape, the nailing head NA tilts in the moving direction. This allows the nailing head NA with a very simple structure.
Can be tilted while reliably moving, and the nailing head NA can be easily switched between normal vertical nailing and inclined nailing. The difference between the nailing head NA and the nailing head NB is that the head swing mechanism 3
0 is the head movement and tilt direction. That is, in the case of tilting, the nailing head NA tilts while moving to the right side in FIG. 10 by extending the rod of the cylinder 31 from the vertical state (dashed line in the figure).
The nailing head NB tilts while moving to the left side in FIG. 10 by contracting the rod of the cylinder 31.

When the two face members 2 are attached to one frame member so that their edges are adjacent to each other, the nailing head NA and the nailing head NB are moved in different directions from the normal state. It is in a tilted state, and the edge portions of the respective face materials are attached while the Neyra carriages 6A and 6B are traveling at the same time.

With reference to FIG. 6, a supplementary description will be given of the traveling of the Neyra vehicles 6A and 6B having the nailing heads NA and NB. As described above, the Neyra vehicles 6A and 6B travel along the erection frame 7. The erection frame 7 includes a rack 34 fixed along the longitudinal direction (horizontal direction),
And a guide member 38 fixed to the side portion. on the other hand,
Nailer trucks 6A and 6B are servo motors 36 that are drive sources.
And a pinion 35 that is directly connected to the drive shaft of the motor 36 and that engages with the rack 34, and two sets of guide wheels 39 that are arranged so as to sandwich the guide member 38 from above and below.
The pinions of the nailer trucks 6A and 6B both engage with the rack 34, and the guide wheels 39 also sandwich the guide member 38.

Next, the traveling platform 5 and the nailing control mechanism will be described with reference to FIG. A rail 55 extending parallel to the stopper 52 is provided on the surface plate 4 outside the stopper 52 arranged on one side of the surface plate 4. The dog 40 is removably attached to the rail 55 and is detachable. Dog 40 is rail 5
5 has a concave portion fitted from above, a plate portion extending from the concave portion, and a detection portion provided upright on the tip of the plate portion. The plate portions have different lengths. Plural kinds (five kinds in the example) are prepared. The dog 40A teaches the nailing head NA (NB) to start and end nailing. Dog 40B teaches the final pillar. The dog 40C teaches the nailing start at the front and rear equal pitches.
When the equal-pitch start dog 40C is detected, nailing is performed on the frame member in the left-right direction at the detection position, and thereafter, every time the traveling platform 5 moves for a predetermined distance, the frame member at the position is nailed. Strike. Therefore, the dog 4
It is not necessary to set 0. Dog 40D teaches beating. The dog 40E teaches the start and end of nailing to the opening formed in the face material 2.

The dog detecting section 41 has a total of five horseshoe-shaped photoelectric sensors, and each sensor is located on the detector bracket 42 extending inwardly from the leg 9 of the traveling platform 5 and the position of the detected section of the dog 40. It is attached to correspond to. Thereby, the dog detection unit 41 can detect and identify the five types of dogs 40.

According to FIG. 8, 40 and a nailing head NA,
The operation of the NB will be described. First, as a preparation stage,
The panel mounting operation and the setting of the dog 40 according to the mounted panel are performed manually. The dog 40 can be easily set by sliding the dog 40 on the rail 55 while visually observing the panel near the placed panel. Next, the traveling table 5 and the Neyra vehicles 6A and 6B are all returned to the origin position. In this state, nails are supplied from the nail supply device 53 to the nailing heads NA and NB, and the nail storage section 22 is filled up. The traveling platform 5 advances on the surface plate 4 from the origin position. Dog 40A while driving
Is detected, the traveling platform 5 is stopped. To be exact, Dog 4
After 0A is detected, the vehicle travels for a predetermined distance and then stops. Then, the nail driving head NB moves the right end from the right end to the left and drives the nails at equal intervals (for example, 100 mm intervals) to remove the dog 40.
The face material is attached to the frame material in the horizontal direction at the position where A is set. Nailing the frame material in the left and right direction,
Left face material detection sensor 23 provided on the head guide member 23
When the face material 2 is no longer detected by A, nailing is stopped, the nailing head NB is stopped after traveling to the left end. The nailing head NA follows the nailing head NB and moves without performing a nailing operation. In this state, both heads are located at the left end. Then, the traveling platform 5 moves forward again.

Next, when the dog 40C is detected, the traveling platform 5
Stops, and the face material 2 is driven onto the frame material in the left-right direction while moving the nailing head NA from the left end to the right side.
Also in this case, the nailing head NB follows the nailing head NA and moves without performing the nailing operation. In this state, both heads NA and NB are located at the right end and are supplied with nails from the nail supply device 53. In principle, both heads NA and NB are supplied with nails each time they return to the right end position. Further, since the nails are supplied while the traveling table 5 is traveling, the nail driving operation to be performed next can be performed immediately after the traveling table 5 is stopped. Once the dog 40C is detected, the traveling platform 5 travels a predetermined distance (equal pitch) from the next time, and the same nail driving is performed. However, if another dog is detected within the range of less than the predetermined distance, it operates according to the instruction of the dog.

If the dog 40D is detected at a position where the traveling table 5 has traveled a predetermined distance in the process of moving the traveling platform 5 forward again and repeating nailing at an equal pitch, the above-described inclined hammering is performed.
Repeated nailing with equal pitch including inclined driving, dog 40A
Is detected again, the nailing to the frame material is finished, and then the nailing is finished once. Then, after detecting the dog 40A for instructing the end of nailing, when the traveling platform 5 is further advanced to detect the dog 40B, it is confirmed that the frame material and the face material 2 do not exist any further, and the traveling platform 5 Will stop.

After that, the nailing heads NA and NB are separated from the left and right ends, and the face material 2 is attached to the frame member in the front-rear direction of the frame body 1 as the traveling platform 5 moves backward. Then, the nailing heads NA and NB also return to the origin position and are supplied with nails. In this state, nailing is completed on the frame members in the front-rear and left-right directions of the frame body 1. Next, the second traveling (forward movement) of the traveling platform 5 is started. This operation is performed only when the dog 40E indicating the presence of the opening is detected in the first run. On the second run, the other dogs are ignored. The following operation is performed at the position where the dog 40E is detected. First, only the nail driving head NB moves to drive a nail on the rear side frame member that constitutes the opening. The nailing head NA is stopped. Then, the traveling platform 5 is moved forward by a slight distance so that the nailing heads NA and NB are disengaged from the frame material, and the nailing heads NA and N are driven.
Move B and the center of the frame body to the left and right. Both heads NA, NB
Stops when the face material detection sensor 23A detects the opening. Then, while the traveling table 5 is moved forward in this state, nailing is performed on the frame member in the front-rear direction which constitutes the opening. When the face material detection sensor detects the face material, the nailing head NA and the nailing head NB move to the left end and stop. Then, the nail driving head NA drives the nail against the frame member in the left-right direction on the front side forming the opening. The nailing head NB does not perform the nailing operation, and the nailing head NA is
Track and stop. When this is completed, the nailing head NA and the nailing head NB return to the origin, and the attachment of the face material 2 to the entire area of the frame 1 is completed.
