Description

Technical Field

[0001] The invention belongs to the field of pneumatic straight nail production equipment, and in particular relates to a straight nail tray loading machine. Background Art

[0002] Pneumatic nails are generally used for decoration. They are usually produced in rows during the production process. In addition, since the nail caps are wide and the nail heads are narrow, in order to increase the number of nails per box and facilitate nailing, the nail caps and nail heads between adjacent rows of nails are oriented in opposite directions to reduce the gaps between adjacent rows of nails.

[0003] Currently, the rows of straight nails are processed and fall directly onto the conveyor belt, and then are manually collected and neatly arranged into pallets.

[0004] There are two spaces on the tray for holding straight nails.

[0005] This means that each machine needs to be equipped with a person to retract and release the straight nails, resulting in high labor costs for manufacturers.

[0006] The existing public document CN201911260516.9 proposes to stack the nails neatly layer by layer on the pallet through a material organization mechanism, but the pallet is still transported on a conveyor belt, and one machine is still required to be equipped with one person, which leads to the problem of high labor costs.

[0007] The existing public document CN201520651319.0 proposes to stack the straight nails alternately in reverse order, then transfer them, and then have the workers collect and package them; although the space occupied by the straight nails during packaging is reduced by stacking the straight nails alternately, in the process of collecting the straight nails, one machine is still required to be equipped with one worker, which leads to the problem of high labor costs.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] It should be noted that the arrow in the figure points to the conveying direction of the conveyor belt, and the conveyor belt includes an annular belt body for conveying straight nails, a frame body for carrying the belt body, and a motor for driving the belt body to rotate.

[0040] Example 1

[0041] like Figure 1-Figure 4 As shown, a straight nail loading machine comprises an alternating frame 24 and a first positioning plate 3 which are sequentially installed along the conveying direction of the conveyor belt 1 and are used to make the straight nails face oppositely and be stacked obliquely on the conveyor belt 1, and a first positioning plate 3 which blocks the straight nails, abutting members 4 for making the straight nails stand upright are installed on the first positioning plate 3, and a leveling mechanism for leveling the upright straight nails and a loading mechanism for loading the leveled straight nails onto the tray are installed on the side of the first positioning plate 3 close to the alternating frame 24;

[0042] The alternating frame 24 is provided with a fifth cylinder 25 and a sixth cylinder 26 which are sequentially installed along the conveying direction of the conveyor belt 1, the telescopic ends of the fifth cylinder 25 and the sixth cylinder 26 are opposite to each other, and horizontal material placing plates 27 are installed on the telescopic ends of the fifth cylinder 25 and the sixth cylinder 26, the telescopic directions of the fifth cylinder 25 and the sixth cylinder 26 are opposite to each other, and a blanking hole 31 for dropping straight nails is provided between the material placing plates 27 on the fifth cylinder 25 and the sixth cylinder 26, and an inclined blanking plate 28 is fixed below the blanking hole 31 at the bottom end of the alternating frame 24, and the inclination direction of the blanking plate 28 is opposite to the conveying direction of the conveyor belt 1;

[0043] The leveling mechanism includes a pressing plate 20 located above the conveyor belt 1. A fourth cylinder 21 is installed on the first positioning plate 3 to drive the pressing plate 20 to move up and down. The pressing plate 20 can level the straight nails with uneven heights through the operation of the fourth cylinder 21.

[0044] The loading mechanism includes a first cylinder 2, which is installed on a frame on one side of the belt body of the conveyor belt 1. The extension direction of the first cylinder 2 is perpendicular to the conveying direction of the conveyor belt 1. The first cylinder 2 is used to push the straight nails away from the conveyor belt 1. The first positioning plate 3 is installed across the belt body of the conveyor belt 1.

[0045] Before the straight nail processing, the conveyor belt 1 is placed on one side of the straight nail processing equipment. Under the processing of the straight nail processing equipment, the processed straight nail directly enters between the telescopic ends of the fifth cylinder 25 and the sixth cylinder 26. At this time, the straight nail tip faces the sixth cylinder 26, and the straight nail cap faces the fifth cylinder 25. The two ends of the straight nail are respectively located on the two material placement plates 27. By operating the sixth cylinder 26 to drive the material placement table to retract, the straight nail tip falls downward onto the blanking plate 28 under the action of gravity, and slides along the blanking plate 28 to the conveyor belt 1; after the lower straight nail is located between the fifth cylinder 25 and the sixth cylinder 26, the fifth cylinder 25 drives the material placement table to retract so that the nail cap of the straight nail falls downward onto the blanking plate 28 under the action of gravity, and slides along the blanking plate 28 to the conveyor belt 1; at this time, the directions of the two consecutive straight nails are just opposite, and by setting the processing speed, the two consecutive rows of straight nails are tilted and stacked together, and so on, multiple straight nails can reduce the occupied space after being erected, and multiple straight nails will not be skewed after being erected, which is convenient for placement.

[0046] The setting of the inclination direction of the blanking plate 28 can make the inclination direction of the straight nails consistent, making it convenient for the subsequent abutment member 4 to erect the straight nails.

[0047] In the present embodiment, in order to make the straight nails fall on the conveyor belt 1 through the blanking plate 28 and be obliquely stacked on the upper straight nail, an inclined baffle plate 29 is installed at the bottom end of the alternating frame 24, and the baffle plate 29 is located on the side of the blanking opening 31 away from the blanking plate 28, and there is a blanking gap between the baffle plate 29 and the blanking plate 28 for making the straight nails fall on the conveyor belt 1; there is a gap between the bottom end of the baffle plate 29 and the belt body of the conveyor belt 1, and the gap is smaller than the thickness of the straight nail, and a baffle block 32 placed on the conveyor belt 1 is provided on the side of the baffle plate 29 away from the blanking plate 28, and the falling position of the straight nail is limited by the baffle plate 29 and the baffle block 32, so that a plurality of straight nails are stacked together in an oblique manner in sequence to prevent the straight nails from sliding and lying flat on the conveyor belt 1 after falling.

[0048] In order to prevent the straight nail from being driven when the fifth cylinder 25 or the sixth cylinder 26 is working, a limit plate 30 is fixedly installed on the alternating frame 24 and is located between the fifth cylinder 25 and the sixth cylinder 26. There are two limit plates 30 and they are arranged opposite to each other. The blanking opening 31 is located between the two limit plates 30. The length direction of the limit plate 30 is parallel to the length direction of the blanking opening 31. Both limit plates 30 are provided with openings for the material placement plate 27 to pass through. The limit passage for the straight nail is formed by the two limit plates 30. In the initial state, the ends of the two material placement plates 27 are both protruding and located between the two limit plates 30. When a material placement plate 27 is driven to retract, the straight nail will not be driven by the blockage of the limit plate 30, but will directly fall onto the blanking plate 28. It should be noted that the end between the two limit plates 30 away from the processing equipment is closed, so that the straight nail falls on the two material placement plates 27 after being pushed by the processing equipment, and will not leave between the two limit plates 30.

[0049] In this embodiment, the abutment 4 is installed through the first positioning plate 3, and the bottom end of the abutment 4 is in contact with the belt surface of the conveyor belt 1. The end of the abutment 4 close to the first cylinder 2 is provided with an abutment slope 5 for erecting the straight nail. The abutment slope 5 is located on the side of the first positioning plate 3 close to the first cylinder 2. The first positioning plate 3 is installed with a second cylinder 6, and the second cylinder 6 is used to drive the abutment 4 to reciprocate along the conveying direction of the conveyor belt 1; the operation of the second cylinder 6 drives the abutment slope 5 on the abutment 4 to protrude from the side of the first positioning plate 3 or retract into the first positioning plate 3.

[0050] It should be noted that the length of the straight nail is greater than the length of the abutting slope 5 .

[0051] Working principle: after the processing of the processing equipment is completed, the rows of straight nails are pushed between the two limiting plates 30, and the straight nails fall on the two material placing plates 27 under the obstruction of the closed ends of the two limiting plates 30. The material placing plates 27 are retracted by the sixth cylinder 26, and the nail tips of the straight nails fall downward along the blanking plates 28 onto the conveyor belt 1. When the straight nails fall on the conveyor belt 1, due to the action of the baffle plates 29, the nail caps of the straight nails will fall toward the first positioning plate 3. When the next straight nail processed by the processing equipment is located on the two material placing plates 27, the fifth cylinder 25 drives the material placing plates 27 to retract, and the nail caps of the straight nails fall downward along the blanking plates 28 onto the conveyor belt 1. When the straight nails fall on the conveyor belt 1, due to the action of the baffle plates 29, the nail tips of the straight nails will fall toward the first positioning plate 3 and be tilted and stacked on the upper straight nail. By analogy, under the continuous processing of the processing equipment, the straight nails will be tilted and stacked together in sequence;

[0052] When the conveyor belt 1 drives the straight nails stacked in sequence to move to the end of the abutment member 4, the straight nails stand up along the abutment slope 5 under the action of the abutment slope 5. Since the length of the straight nail is greater than the length of the abutment slope 5, the straight nail will leave the abutment slope 5 and continue to stand up along the side of the first positioning plate 3. At this time, the second cylinder 6 works to retract the abutment slope 5 into the first positioning plate 3. Driven by the conveyor belt 1, the straight nails gradually stand up and stick to the side of the first positioning plate 3. At this time, the fourth cylinder 21 works to drive the pressing plate 20 to move up and down to adjust the height difference. The uneven straight nails are leveled. As the conveyor belt 1 works, the subsequent straight nails will gradually stand up because the front straight nails have been erected. After the length of the erected straight nails reaches the required length, the first cylinder 2 works to push the erected straight nails away from the conveyor belt 1 to the pallet on one side of the conveyor belt 1, and the staff can collect the pallet. After the first cylinder 2 pushes the straight nails away from the conveyor belt 1 and returns to its position, the second cylinder 6 works to drive the abutment slope 5 on the abutment 4 to re-protrude from the side of the first positioning plate 3, so that the subsequent straight nails can continue to stand up.

[0053] In combination with the above, the present application guides the tilted stacked straight nails to stand upright and push them away from the conveyor belt 1 through the arrangement of the alternating frame 24, the first positioning plate 3, the first cylinder 2, the pressure plate 20 and the abutment 4, thereby reducing manual intervention in the collection of straight nails, reducing manual work intensity, and increasing the number of machines that can be supervised by one person, effectively solving the current problem of high labor costs in straight nail production.

[0054] Example 2

[0055] like Figure 5 , Figure 6 and Figure 7 As shown, the structure of this embodiment is roughly the same as that of embodiment 1. This embodiment is further optimized on the basis of embodiment 1. When the first cylinder 2 pushes the straight nail back to its original position, it is easy to hit the straight nail subsequently conveyed by the conveyor belt 1, causing the straight nails to be scattered.

[0056] In this embodiment, a third cylinder 7 is installed on the side of the first cylinder 2 away from the first positioning plate 3, the telescopic direction of the third cylinder 7 is perpendicular to the conveying direction of the conveyor belt 1, and a partition plate 8 that can be inserted between the straight nails is installed at the telescopic end of the third cylinder 7, and the telescopic end of the first cylinder 2 is located between the first positioning plate 3 and the partition plate 8;

[0057] The dividing plate 8 is a horizontally placed long strip, and one end of the dividing plate 8 facing the conveyor belt 1 is provided with an arc corner to facilitate insertion between the straight nails;

[0058] The position for installing the partition plate 8 is determined according to the required arrangement length of the erected nails. The partition plate 8 is installed between the erected nails and the inclined nails. After the nails on the conveyor belt 1 are erected to the required arrangement length (at this time, there is a gap between the erected nails and the subsequent inclined nails), the third cylinder 7 first drives the partition plate 8 to be inserted between the nails, and then the first cylinder 2 works to push the erected nails away from the conveyor belt 1; when returning, the first cylinder 2 returns first, and the third cylinder 7 and the second cylinder 6 return later than the first cylinder 2.

[0059] In this embodiment, the third cylinder 7 and the dividing plate 8 are provided to separate the erected nails from the subsequently inclined nails, making it easier for the first cylinder 2 to push the erected nails away from the conveyor belt 1 .

[0060] In order to facilitate the monitoring of the status of the straight nail, in this embodiment, a 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 detection surface of the first proximity switch 17 is located above the abutment protrusion of the abutment member 4 and lower than the height of the straight nail after it is erected; through the setting of the first proximity switch 17, two states of the straight nail can be detected: the first is that the straight nail leaves the abutment slope 5 and connects with the first positioning plate 3 and is detected by the first proximity switch 17. At this time, the second cylinder 6 drives the abutment slope 5 on the abutment member 4 to retract the first positioning plate 3; the second is that the straight nail is erected and connects with the side of the first positioning plate 3.

[0061] In order to facilitate the judgment of the working time of the third cylinder 7, a second positioning plate 19 is installed on the conveyor belt 1 across the top of the conveyor belt 1. The position of the second positioning plate 19 is installed according to the required arrangement length of the vertical nails. The second positioning plate 19 is located on the side of the dividing plate 8 away from the first positioning plate 3. The second positioning plate 19 is provided with an opening for the vertical nails to pass through. A second proximity switch 18 for detecting the height of the vertical nails is installed above the opening. The second proximity switch 18 is set to monitor whether the vertical nails have reached the required arrangement length, so that the third cylinder 7 can drive the dividing plate 8 to insert between the vertical nails.

[0062] Since the straight nails are initially stacked in an inclined manner, the heights of the erected straight nails are uneven due to the friction between the straight nails after they are erected, and they are easily scattered when being pushed by the first cylinder 2. Therefore, in this embodiment, a pressing plate 20 is provided above the conveyor belt 1, and a fourth cylinder 21 for driving the pressing plate 20 to rise and fall is installed on the first positioning plate 3 and the second positioning plate 19. A gap is left between one end of the pressing plate 20 and the side of the first positioning plate 3 (the gap is smaller than the thickness of a single row of straight nails), and the other end of the pressing plate 20 passes through the opening on the second positioning plate 19;

[0063] The pressure plate 20 is provided with a detection hole for facilitating detection by the second proximity switch 18;

[0064] When the first proximity switch 17 detects that the straight nail is in the second state, the fourth cylinder 21 works to drive the pressing plate 20 to move up and down to press the uneven straight nails into place; the setting of the pressing plate 20 passing through the opening can also flatten the straight nails close to the second proximity switch 18 to avoid uneven straight nails close to the second proximity switch 18.

[0065] Example 3

[0066] like Figure 8 and Fig. 9 As shown, the structure of this embodiment is roughly the same as that of embodiment 2. This embodiment is further optimized on the basis of embodiment 2. In this embodiment, in order to collect the straight nails pushed out by the first cylinder 2 and further reduce the labor cost, a frame 9 is installed on the side of the conveyor belt 1 away from the first cylinder 2. A first lifting motor 10, a rotating motor 11 and a pallet plate 12 are installed in the frame 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. The pallet plate 12 is horizontally installed on the rotating motor 11 and is driven to rotate horizontally by the rotating motor 11. The pallet plate 12 is used to place the pallet;

[0067] A tray loading opening is provided at the upper end of the frame 9, and the tray loading opening is used to allow the straight nails pushed by the first cylinder 2 to enter the tray on the tray rack 14;

[0068] Since the pallet currently has two grids, after the first cylinder 2 pushes the straight nails to fill one grid of the pallet, the first lifting motor 10 drives the rotating motor 11 to descend to make the pallet leave the loading port. At this time, the rotating motor 11 drives the pallet plate 12 to rotate the pallet 180 degrees, so that the pallet grid without straight nails can hold the straight nails pushed by the first cylinder 2 next time; the staff only needs to take away the full pallet, which further reduces manual intervention, further reduces labor costs, and increases the number of machines that can be supervised by one person.

[0069] In this embodiment, a plate-loading mechanism is also installed in the frame 9, and the plate-loading mechanism includes a second lifting motor 13 located on one side of the first lifting motor 10, a pallet rack 14 driven to lift by the second lifting motor 13, and an upper plate cylinder 15. A limit fence 16 is installed in the frame 9 to block along the pallet lifting trajectory. The upper plate cylinder 15 is installed on the frame 9 on one side above the limit fence 16. The upper plate cylinder 15 is used to push the pallet on the pallet rack 14 onto the push plate.

[0070] The second lifting motor 13 is used to drive the pallet on the pallet rack 14 to rise above the limiting enclosure 16, and the upper plate cylinder 15 is used to push the pallet raised above the limiting enclosure 16 onto the pallet plate 12;

[0071] Multiple pallets can be stacked on the pallet rack 14, and the limiting fence 16 is used to limit the multiple pallets. As the pallets on the pallet plate 12 are removed, the upper plate cylinder 15 will push the pallet raised above the limiting fence 16 onto the pallet plate 12, making it convenient to place the straight nails next time.

[0072] It should be noted that, in the present embodiment, a third proximity switch 22 may be installed on the fixed seat of the rotating motor 11, and a detection hole compatible with the third proximity switch 22 may be opened on the pallet plate 12, and the third proximity switch 22 may be used to detect whether there is a pallet on the pallet plate 12; a fourth proximity switch 23 may be installed on the frame 9 on one side above the limit enclosure 16, and the fourth proximity switch 23 may be used to detect whether there is a pallet rising above the limit enclosure 16.

[0073] In combination with the above three embodiments, the working principle of the present application is as follows: after the processing of the processing equipment is completed, the rows of straight nails are pushed between the two limiting plates 30, and the straight nails fall on the two material placing plates 27 under the obstruction of the closed ends of the two limiting plates 30, and the material placing plates 27 are driven to retract by the sixth cylinder 26, and the nail tips of the straight nails fall downward along the blanking plates 28 onto the conveyor belt 1, and when the straight nails fall on the conveyor belt 1, due to the action of the baffle plates 29, the nail caps of the straight nails will fall toward the first positioning plate 3, and when the next straight nail processed by the processing equipment is located on the two material placing plates 27, the fifth cylinder 25 drives the material placing plates 27 to retract, and the nail caps of the straight nails fall downward along the blanking plates 28 onto the conveyor belt 1, and when the straight nails fall on the conveyor belt 1, due to the action of the baffle plates 29, the nail tips of the straight nails will fall toward the first positioning plate 3 and be tilted and stacked on the upper straight nail, and so on, under the continuous processing of the processing equipment, the straight nails will be tilted and stacked together in sequence;

[0074] When the conveyor belt 1 drives the tilted stacked straight nails to move to the abutment 4, under the action of the abutment slope 5, the straight nails begin to stand up along the abutment slope 5 and continue to stand up in contact with the side of the first positioning plate 3. After the first proximity switch 17 detects the straight nail, the second cylinder 6 works to retract the abutment slope 5. Driven by the conveyor belt 1, the straight nail continues to stand up. After the first proximity switch 17 detects the straight nail for the second time, the fourth cylinder 21 works to drive the pressing plate 20 to press down reciprocatingly. At this time, the conveyor belt 1 continues to move, and the pressing plate 20 presses down reciprocatingly. When the second proximity switch 18 detects that the height of the straight nail reaches the set value, the fourth cylinder 21 drives the pressing plate 20 back to the initial height, and the third cylinder 7 works to drive the dividing plate 8 to be inserted between the straight nails. After the third cylinder 7 is in place, the first cylinder 2 pushes the straight nail onto the pallet plate 12. After the pallet returns to its original position, the third cylinder 7 then drives the dividing plate 8 to return to its original position. At this time, the straight nails blocked by the dividing plate 8 tilt down again and continue to be driven by the conveyor belt 1; after the first cylinder 2 pushes the straight nails into the pallet, the first lifting motor 10 works to lower the pallet. After the pallet descends and leaves the loading port, the rotating motor 11 works to rotate the pallet to bring the empty pallet grid close to the conveyor belt 1 to hold subsequent straight nails; after the two grids on the pallet are full, the staff takes the pallet away, and after the third proximity switch 22 detects that there is no pallet on the pallet plate 12, the second lifting motor 13 works to raise a pallet on the pallet rack 14 to above the limiting enclosure 16. After the fourth proximity switch 23 detects the pallet, the upper plate cylinder 15 works to push the pallet onto the pallet plate 12, which is convenient for holding subsequent straight nails.

[0075] In summary, the present application reduces manual intervention in the work of collecting straight nails by standing the straight nails upright and loading them onto trays. One person can simultaneously supervise multiple machines, effectively solving the current problem of high labor costs in straight nail production.

[0076] As a conventional technical means for 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 plate cylinder 15, the third proximity switch 22 and the fourth proximity switch 23 can be integrated and controlled through a controller (PLC). Manual labor only needs to collect the tray interface after it is full, which can further increase the number of machines that can be supervised by one person, and further reduce labor costs.
