DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nailing device used for packing laminates.

An example of a laminate package (hereinafter referred to as a package) to which the apparatus of the present invention is applied is shown in FIGS. 1 and 2.

That is, the package M wraps the laminate 1 with wrapping paper 2, applies vertical skids 3, 3 to both edges in the longitudinal direction of the lower surface, binds the laminate 1 together with each vertical skid 3 with a vertical band 4, Further, two or three horizontal skids 5, 5 are applied to the outer surface of the two vertical skids 3, 3, and the laminate 1 is bound together with each horizontal skid 5 using horizontal bands 6, 6, . . . and packed. It is. In this case, if only the vertical and horizontal straps are hung, the load may become distorted, so as shown in FIG. Nails 7 were driven into holes 3 and B to secure both skids 3 and 5.

However, since this work required the nails 7 to be nailed accurately within an extremely limited area of the horizontal skid 5, conventionally this work was carried out exclusively by hand.
This work was extremely time-consuming and was a major cause of hindering rationalization of the laminate packing work.

The present invention provides a device that can reliably nail vertical skids and horizontal skids assembled into a package without requiring any manual labor in a laminate packaging work line. That is, the present invention provides a nailing device that uses a nailing head to nail together a vertical skid applied to both side edges of one side of a package and a horizontal skid combined orthogonally to the lower surface of the vertical skid. a dolly that is automatically moved forward and backward along the carry-in line of the package; and a slide base that is mounted on the dolly and is moved forward and backward by automatic feed toward the carry-in line of the package, and the slide base moves forward and backward along the carry-in line of the package. A first sensor detects the outer surface position of the vertical skid of the package carried in in connection with the feeding, a switch that operates at the detection position to stop the feeding of the slide base, and one side of the horizontal skid due to the moving feed of the cart. a second sensor that detects the position of the nailer, and a switch that stops the feed of the cart at the detected position; the nailing head installed on the slide base in line with the center line of the horizontal skid detected by the second sensor; a switch that operates to stop feeding the slide base when the slide base further advances along the center line of the horizontal skid and reaches a preset nailing reference position within the width of the vertical skid; and a nail. A third method detects the side position of the horizontal skid when the nailing head reaches directly below a preset nailing point within the width of the horizontal skid by moving the cart forward or backward from the driving reference position along the carry-in line. This nailing device is characterized by having a sensor and a switch that operates at the sensor's detection position to stop the feeding of the truck. Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 4 and 5, a machine stand 9 is disposed along a conveyor device 8 that carries the package M therein. A pair of guides 10 , 10 are provided on the machine base 9 in parallel with the conveyance line of the conveyor device 8 , and a cart 11 is installed so as to be able to move laterally along the guides 10 , 10 . The rod 12a of the driving cylinder device 12 is connected to the truck 11. On the trolley 11, a slide base 14 whose upper and lower sides are supported by guide rollers 13, 13, .
The rod 15a of the feed drive cylinder device 15 supported by the screwdriver 1 is connected to the slide base 14, and the nailing head 16 is installed upward on the upper surface of the front end of the slide base 14. The nail driving head 16 is a known device that receives nails one by one from the nail loading section 17 using air pressure and drives the nails upward.

The slide base 14 further detects the positions of the outer surface of the vertical skid 3 and the horizontal skid 5 of the package M carried onto the conveyor device 8, respectively, and sets a reference position for nailing by the nailing head 16. 1
It is equipped with a sensor 18, a second sensor 19, and a pair of third sensors 20a, 20b for detecting nailing points set on both sides of the nailing reference position at a certain distance within the width of the horizontal skid 5. There is. Each sensor consists of the following structure.

In FIGS. 6 and 7, the first sensor 18 is rod-shaped, has a pusher 18a at its tip, and is biased toward the conveyor device 8 by a spring 21 to form a cylinder supported by a bracket 14a on the slide base 14. It is slidably supported by the body 22. Also,
An operating piece 23 is attached to the rear end, and behind the first sensor 18 there is a vertical skid detection switch 24 that is activated by contact with the operating piece 23 to issue a feed stop command to the cylinder device 15, and a slide base feed regulation switch. 25 are arranged. The distance between both switches 24 and 25 is 1/1 of the width of the vertical skid 2.
The distance is set to be slightly larger than 2. The second sensor 19 has an arm shape that projects diagonally forward, and is supported on a receiving plate 14b by a bracket 14a at a position slightly below the installation height of the first sensor 18.
It is installed horizontally rotatably about the bin 26. At the base end of the second sensor 19 is a lateral skid detection switch 27 that is activated in response to rotational displacement when the arm end of the sensor 19 comes into contact with the lateral skid 5, and issues a feed stop command to the cylinder device 12. is set up. In FIG. 7, the distance between the contact part of the second sensor 19 and the center line of the sensor of the nailing head 16 is set to 1/2 of the width d of the horizontal skid 5. When the second sensor 19 contacts one side of the horizontal skid 5 and the truck 11 stops, the nailing head 16
will stop at a position on the center line of the horizontal skid 5.

The third sensors 20a, 20b are composed of rollers,
It detects the nailing points A and B on both sides of the nailing reference position determined by the first sensor 18 and the second sensor 19, and the nailing head 16 is moved at an interval slightly wider than the width d of the horizontal skid 5. The support shafts 28a, 28b of the respective sensors 20a, 20b are set to face each other on both sides of the sensor 20a, 20b on the support plate 14b.
29b, and operating pieces 30a and 30b attached to each shaft end are linked to nailing point detection switches 31a and 31b, respectively.

Both switches 31a and 31b are activated when the third sensor 20a or 20b detects the horizontal skid 5, and issue a feed stop command to the cylinder device 12.

In the figure, 32a is an upper limit detection switch of the nailing head 16, and 32b is a lower limit detection switch.

The conveyor device 8 has a large number of pieces 33 arranged at regular intervals on the center and both sides of the upper surface thereof.
33... are provided. Each piece 33 regulates the supporting height of the package M carried into the conveyor device 8 while being straddled over its upper surface.

That is, with the package M supported on each piece 33, the vertical skid 3 faces the first sensor 18, and the horizontal skid 5 faces the second sensor 19.
The support height is regulated so that the third sensors 20a and 20b face each other.

In the embodiment, the package M is placed on the pieces 33, 33, . The operating procedure of the apparatus of the present invention will be explained below with reference to FIGS.

(1) First, when the slide base 14 is moved forward toward the package M by driving the cylinder device 15, the pusher 18a of the first sensor 18 comes into contact with the outer surface of the vertical skid 3, and the sensor 18 is pressed against the spring 21. The operation piece 23 operates the vertical skid detection switch 24 to stop the movement of the slide base 14. (Figure 8a).

(2) Next, when the carriage 11 is moved in one direction along the machine base 9 by driving the cylinder device 12,
The second sensor 19 comes into contact with one side of the lateral skid 5 and is rotationally displaced, and the lateral skid detection switch 27
is operated to stop the carriage 11 from moving horizontally. At this time, the center of the nailing head 16 stops on the center line of the horizontal skid 5. (Figure 8b).

(3) When the slide base 14 is further advanced from this position, the nailing head 16 enters below the package M along the center line of the horizontal skid 5.

On the other hand, the first sensor 18 receives resistance from the vertical skid 3 and retreats beyond the switch 24, and then the operation piece 23 operates the slide base feed regulation switch 25 to stop the feed of the slide base 14. (Figure 8c).

At this time, the center of the nailing head 16 is located beyond the center line of the vertical skid 3 and directly below the center line of the horizontal skid 5, and this position becomes the nailing reference position 0. (Figure 8 d).

(4) When the cart 11 is further moved in one direction from this position, one sensor 20a of the pair of third sensors 20a and 20b installed across the nailing head 16 is placed on the side surface of the horizontal skid 5. Upon contact, the nailing point setting switch 31a is operated, and the feeding of the cart 11 is immediately stopped. As a result, the center of the nailing head 16 is slightly shifted laterally from the nailing reference position 0, and moves to the nailing point A, which avoids the vertical and horizontal bands 4 and 6. (Fig. 8H).

(5) Next, raise the nailing head 16 and drive the nail supplied from the nail loading section 17 into the nailing point A.

The upper limit of the nailing head 16 is detected by the switch 32a, and its upward movement is stopped. When the nail driving operation is completed, the nail driving head 16 is lowered, and the lower limit thereof is detected by the switch 32b and stopped.
(Figure 8).

(6) Next, to drive the nail to nailing point B on the other side,
The cart 11 is moved in the opposite direction. Thereafter, similarly to the above, the third sensor 20b is connected to the horizontal skid 5.
The cart 11 stops when it comes into contact with the other side, and the nailing head 16 moves to the other nailing point B. (8th
Figure).

(7) Next, the nail driving head 16 is raised to drive a nail to the nail driving point B which is out of the vertical and horizontal bands 4 and 6, and after the nail driving is completed, the nail driving head 16 is lowered. The upper and lower limit positions of the nailing head 16 are set to the switches 32a and 3.
The point detected in 2b is the same as in the previous case.

(8) When the nailing operation at a specific location is completed, the cylinder device 12 is driven to return the cart 11 to the nailing reference position. Thereafter, the cylinder device 15 is driven to move the slide base 14 backward, and the cylinder device 12 is driven to return the truck 11 to the standby position.

As for the packing mode of the package, when the length of the laminate is short, the horizontal skid is 2.
When the book or laminate is long, three horizontal skids are used, and as is clear from Figures 1 and 2,
The locations that require nailing are on both sides of the package, and therefore it is necessary to install the apparatus of the present invention on both sides of the package conveyance line.

When the line has sufficient capacity, one device of the present invention is installed on each side of the conveyor line, and while sequentially feeding the conveyor device, each cross section between the vertical skid and the horizontal skid of the package is The nailing operation is performed by repeating the above operation, or by moving the cart while the conveyor device is stopped. In addition, if there is not enough line capacity, two carts are installed on each side of the conveyor line, as shown in Figure 5, and one of the carts is used to drive nails at the two points where both skids intersect. All you have to do is let them do it.

As described above, the present invention detects the positions of the vertical skid and the horizontal skid assembled in the package, first moves the nailing head to the nailing reference position along the center line of the horizontal skid, and then Since the nailing head is moved left and right from the nailing reference position and nails are driven at each nailing point A and B, both skids can be nailed without damaging the vertical and horizontal bands, which was impossible to do by hand. This method has the effect of automatically performing the nailing work of packaging bodies within the line, and dramatically improving the work efficiency compared to the conventional method.
