Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0036] It should be noted that the arrow in the figure points to the conveying direction of the conveying belt.

[0037] Embodiment 1

[0038] As Figure 1 and Figure 2 shown, a straight nail tray loading machine comprises a first positioning plate 3 installed horizontally above the belt body of a conveying belt, an abutting piece 4 for making the straight nail stand up is installed on the first positioning plate 3, a flattening mechanism for flattening the standing straight nail is installed on the conveying belt 1 or the first positioning plate 3, and a tray loading mechanism for loading the flattened straight nail into a tray is also installed on the conveying belt.

[0039] Specifically, in the embodiment, the abutting member 4 is installed on the first positioning plate 3, the bottom end of the abutting member 4 abuts against the surface of the belt body of the conveying belt 1, the end of the abutting member 4 facing the direction of the straight nails is provided with an abutting slope 5 for making the straight nails stand up in sequence, the abutting slope 5 is located on the side of the first positioning plate 3 facing the direction of the straight nails, the second air cylinder 6 is installed on the first positioning plate 3, and the second air cylinder 6 is used to drive the abutting member 4 to reciprocate along the conveying direction of the conveying belt 1; the abutting slope 5 on the abutting member 4 is protruded from the side of the first positioning plate 3 or retracted into the first positioning plate 3 through the work of the second air cylinder 6.

[0040] It should be noted that the length of the straight nail is greater than the length of the abutting slope 5.

[0041] In the embodiment, the flattening mechanism is installed on the first positioning plate 3, the flattening mechanism includes a pressing plate 20 located above the conveying belt 1, the fourth air cylinder 21 for driving the pressing plate 20 to move up and down is installed on the first positioning plate 3, the gap between the side of the pressing plate 20 and the side of the first positioning plate 3 is matched, and the gap is not greater than the thickness of the straight nail.

[0042] In the embodiment, the tray loading mechanism includes the first air cylinder 2 installed on the conveying belt 1, the first air cylinder 2 is located on the side of the first positioning plate 3 facing the direction of the straight nails, the first air cylinder 2 is used to push the straight nail flattened by the pressing plate 20 away from the conveying belt 1 to the tray, and the extension end of the first air cylinder 2 is equal in length to or shorter than the length of the pressing plate 20.

[0043] In the embodiment, the first proximity switch 17 for detecting the distance between the straight nail and the side of the first positioning plate 3 is installed on the first positioning plate 3, and the first proximity switch 17 is located above the abutting slope 5; through the setting of the first proximity switch 17, two states of the straight nail can be detected: the first state is that the straight nail is detected by the first proximity switch 17 after the straight nail abuts against the abutting slope 5 and the first positioning plate 3, at this time, the second air cylinder 6 drives the abutting slope 5 on the abutting member 4 to retract into the first positioning plate 3; the second state is that the straight nail abuts against the side of the first positioning plate 3 after the straight nail stands up.

[0044] The working principle is that when the straight nails in the inclined stack are moved to the end of the abutting piece 4 under the driving of the conveying belt 1, the straight nails are erected along the abutting slope 5 under the driving of the abutting slope 5 and the conveying belt 1, and since the length of the straight nails is greater than the length of the abutting slope 5, the straight nails will continue to be erected along the side of the first positioning plate 3 away from the abutting slope 5, at this time, the first proximity switch 17 detects the straight nails, and the second air cylinder 6 works to make the abutting slope 5 retract into the first positioning plate 3, and under the driving of the conveying belt 1, the straight nails are gradually erected and attached to the side of the first positioning plate 3, and after the first proximity switch 17 detects that the distance between the straight nails and the first positioning plate 3 is further reduced, the fourth air cylinder 21 drives the pressing plate 20 to move up and down to flatten the straight nails with uneven heights, and as the conveying belt 1 works, the subsequent straight nails will also be gradually erected, and after the length of the erected straight nails reaches the required length, the first air cylinder 2 works to push the erected straight nails away from the conveying belt 1 to the tray, and the workers can collect them; after the first air cylinder 2 pushes the straight nails away from the conveying belt 1 and returns, the second air cylinder 6 works to drive the abutting slope 5 on the abutting piece 4 to protrude from the side of the first positioning plate 3 again, so as to facilitate the subsequent straight nails to continue to be erected.

[0045] In combination with the above, the straight nails in the inclined stack are guided to be erected, flattened and pushed away from the conveying belt 1 through the setting of the first positioning plate 3, the first air cylinder 2, the abutting piece 4 and the pressing plate 20, the manual intervention work for collecting the straight nails is reduced, the working strength of the workers is reduced, the number of workers who can watch the machine is increased, and the problem of high labor cost in the production of straight nails is effectively solved.

[0046] Embodiment 2

[0047] As shown in Figure 3 , Figure 4 and Figure 5 , the embodiment is substantially the same as that of embodiment 1, and the embodiment is further optimized on the basis of embodiment 1. Since the first air cylinder 2 pushes the straight nails to return, it is easy to collide with the subsequent straight nails conveyed by the conveying belt 1, resulting in the scattering of the straight nails.

[0048] In this embodiment, a third air cylinder 7 is installed on the side of the first air cylinder 2 away from the first positioning plate 3, the extension direction of the third air cylinder 7 is perpendicular to the conveying direction of the conveying belt 1, the extension end of the third air cylinder 7 is provided with a partition plate 8 which can be inserted between the straight nails, and the extension end of the first air cylinder 2 is located between the first positioning plate 3 and the partition plate 8.

[0049] The partition plate 8 is a horizontally placed long strip plate body, and one end of the partition plate 8 towards the conveying belt 1 is provided with a circular arc corner to facilitate the insertion between the straight nails.

[0050] The position of the partition plate 8 is determined according to the required arrangement length of the erected straight nails, and the partition plate 8 is installed between the erected straight nails and the inclined straight nails. After the straight nails are arranged on the conveying belt 1 to the required length (at this time, there is a gap between the erected straight nails and the subsequent inclined straight nails), the third cylinder 7 first drives the partition plate 8 to be inserted between the straight nails, and then the first cylinder 2 works to push the erected straight nails away from the conveying belt 1. When returning, the first cylinder 2 is first returned, and the third cylinder 7 and the second cylinder 6 are returned later than the first cylinder 2.

[0051] In this embodiment, the third cylinder 7 and the partition plate 8 are arranged to separate the erected straight nails and the subsequent inclined straight nails, which facilitates the first cylinder 2 to push the erected straight nails away from the conveying belt 1.

[0052] In order to facilitate the judgment of the working time of the third cylinder 7, a second positioning plate 19 is also installed on the conveying belt 1, which crosses above the body of the conveying belt 1. The position of the second positioning plate 19 is determined according to the required arrangement length of the erected straight nails. The second positioning plate 19 is located on the side of the partition plate 8 away from the first positioning plate 3. An opening for the straight nails to pass through is arranged on the second positioning plate 19. A second proximity switch 18 for detecting the height of the straight nails is installed above the opening. The second proximity switch 18 is arranged to monitor whether the erected straight nails reach the required arrangement length, which facilitates the third cylinder 7 to drive the partition plate 8 to be inserted between the straight nails.

[0053] One end of the pressing plate 20 is left with a gap (which is smaller than the thickness of a single row of straight nails) from the side surface of the first positioning plate 3. The other end of the pressing plate 20 passes through the opening of the second positioning plate 19. The second positioning plate 19 is also provided with a fourth cylinder 21 for driving the pressing plate 20 to move up and down.

[0054] A detection hole is arranged on the pressing plate 20 for the second proximity switch 18 to detect.

[0055] When the first proximity switch 17 detects that the straight nails are in the second state, the fourth cylinder 21 works to drive the pressing plate 20 to move up and down reciprocally to press the uneven straight nails to be in order. The arrangement of the pressing plate 20 passing through the opening can also press the straight nails close to the second proximity switch 18 to be flat, avoiding the unevenness of the straight nails close to the second proximity switch 18.

[0056] Embodiment 3

[0057] As Figure 6 and Figure 7As shown, the structure of the embodiment is substantially the same as that of embodiment 2, and the embodiment is further optimized on the basis of embodiment 2. In order to collect the straight nails pushed out by the first air cylinder 2 and further reduce the labor cost, a rack 9 is installed on the side of the conveying belt 1 away from the first air cylinder 2, the first lifting motor 10, the rotating motor 11 and the tray plate 12 are installed in the rack 9, the rotating motor 11 is installed on the upper end of the first lifting motor 10 and is driven to lift by the first lifting motor 10, and the tray plate 12 is horizontally installed on the rotating motor 11 and is driven to rotate horizontally by the rotating motor 11. The tray rack 14 is used to place the tray;

[0058] A tray loading port is formed in the upper end of the rack 9, which is used to make the straight nails pushed by the first air cylinder 2 enter the tray on the tray rack 14;

[0059] Since the current tray is two compartments, after the first air cylinder 2 pushes the straight nails to fill one compartment of the tray, the first lifting motor 10 drives the rotating motor 11 to descend to make the tray leave the tray loading port. At this time, the rotating motor 11 drives the tray plate 12 to rotate the tray by 180 degrees, so that the compartment of the tray which is not filled with straight nails can hold the straight nails pushed by the first air cylinder 2 next time. The staff only needs to take away the full tray, which further reduces the intervention of manual work and further reduces the labor cost, and increases the number of machines that can be supervised by one person.

[0060] In the embodiment, an upper tray mechanism is also installed in the rack 9. The upper tray mechanism includes a second lifting motor 13 located on one side of the first lifting motor 10, a tray rack 14 driven to lift by the second lifting motor 13, and an upper tray air cylinder 15. A limiting fence 16 is installed in the rack 9 along the lifting track of the tray. The upper tray air cylinder 15 is installed on the rack 9 on one side above the limiting fence 16. The upper tray air cylinder 15 is used to push the tray on the tray rack 14 to the tray plate;

[0061] The second lifting motor 13 is used to drive the tray on the tray rack 14 to rise above the limiting fence 16, and the upper tray air cylinder 15 is used to push the tray rising above the limiting fence 16 to the tray plate 12;

[0062] The tray rack 14 can stack multiple trays, and the limiting fence 16 is used to limit the multiple trays. As the tray on the tray plate 12 is taken away, the upper tray air cylinder 15 pushes the tray rising above the limiting fence 16 to the tray plate 12, which is convenient for holding the straight nails next time.

[0063] It should be noted that in the present embodiment, a third proximity switch 22 can be installed on the fixed seat of the rotating motor 11, and a detection hole adapted to the third proximity switch 22 is formed on the tray plate 12, so as to detect whether there is a tray on the tray plate 12 through the third proximity switch 22; and a fourth proximity switch 23 is installed on the rack 9 on the side above the limiting fence 16, so as to detect whether a tray is raised above the limiting fence 16 through the fourth proximity switch 23.

[0064] In combination with the above three embodiments, the working principle of the present application is as follows: when the straight nails in the inclined state are moved to the abutting piece 4 by the conveying belt 1, the straight nails start to stand up along the abutting slope 5 under the action of the abutting slope 5 and continue to stand up after being in contact with the side surface of the first positioning plate 3, after the straight nails are detected by the first proximity switch 17, the second cylinder 6 works to make the abutting slope 5 retract, the straight nails continue to stand up under the driving of the conveying belt 1, after the straight nails are detected by the first proximity switch 17 for the second time, the fourth cylinder 21 works to drive the pressing plate 20 to reciprocally press down, at this time, the conveying belt 1 continues to move, the pressing plate 20 reciprocally presses down, after the straight nails are detected by the second proximity switch 18 to reach a set value, the fourth cylinder 21 drives the pressing plate 20 to return to the initial height, the third cylinder 7 works to drive the partition plate 8 to insert between the straight nails, after the third cylinder 7 is in place, the first cylinder 2 pushes the straight nails to the tray on the tray plate 12 and then returns to the original position, and then the third cylinder 7 drives the partition plate 8 to return to the original position, at this time, the straight nails blocked by the partition plate 8 re-tilt and fall down to be driven by the conveying belt 1; after the straight nails are pushed into the tray by the first cylinder 2, the first lifting motor 10 works to make the tray descend, after the tray descends and leaves the tray loading port, the rotating motor 11 works to rotate the tray to close the empty tray grid to the conveying belt 1, so as to hold the subsequent straight nails; after the two grids on the tray are filled, a worker takes away the tray, after the third proximity switch 22 detects that there is no tray on the tray plate 12, the second lifting motor 13 works to make a tray on the tray rack 14 rise above the limiting fence 16, after the fourth proximity switch 23 detects the tray, the tray cylinder 15 works to push the tray to the tray plate 12, so as to facilitate holding the subsequent straight nails.

[0065] In summary, the present application vertically stands up and loads the straight nails, reduces the manual intervention in the collection of the straight nails, one person can simultaneously supervise multiple machines, and effectively solves the problem of high labor cost in the production of straight nails.

[0066] As a routine technical means of those skilled in the art, the first cylinder 2, the second cylinder 6, the third cylinder 7, the fourth cylinder 21, the first proximity switch 17, the second proximity switch 18, the first lifting motor 10, the rotating motor 11, the second lifting motor 13, the upper disc cylinder 15, the third proximity switch 22 and the fourth proximity switch 23 can be integrated controlled through the controller (PLC), and the artificial only needs to collect the full tray interface, which can further increase the number of people who can supervise the machine, and further reduce the labor cost.
