Description

TECHNICAL FIELD

[0001] The present application relates to the field of nailing equipment, in particular to a long and short nail programmable automatic nailing device. BACKGROUND

[0002] Wooden pallets are a common tool for packaging and transporting goods, made of wood, with certain load-bearing capacity and stability, commonly used in the logistics industry for stacking, storing and transporting various goods. Wooden pallets are usually composed of four components: slats, crossbeams, blocks and nails. During the manufacturing process, nails are used to connect the slats, crossbeams and blocks, fixing them together to form the structure of the pallet. Existing processing tools generally fix the nail gun on the equipment and complete the nailing operation through an auxiliary control system. In order to achieve automation, a nail feeding device is usually provided to supply nails to the nail gun. However, the existing nail feeding device has a problem that multiple nails may be fed into the nailing device at a time during the feeding process, which may cause the device to jam, thereby reducing the working efficiency of the automatic nailing machine.

[0003] The existing automatic nailing equipment mainly has the following problems:

[0004] 1. Positioning accuracy: Automatic nailing equipment needs to accurately position the position of the nails for striking. If the positioning is not accurate, the nails may be struck in the wrong position or fail to be completely struck into the target, which may affect the structural strength of the material or cause unstable assembly.

[0005] 2. Nail selection and supply: When using automatic nailing technology, it is necessary to ensure the correct selection of suitable nail types and sizes. If the selected nails are not suitable, the nails may be too long or too short, unable to provide sufficient holding force or damage the surface of the target. In addition, it is also an important issue to ensure sufficient supply of nails to avoid production interruption or delay.

[0006] 3. Precision and consistency: Automatic nailing technology needs to maintain consistent precision in multiple operations. If the precision of the equipment is unstable, the quality of the nails struck at different positions or different times may be inconsistent, which may affect the overall quality and reliability of the product.

[0007] 4. Safety: Automatic nailing equipment needs to ensure safety during operation. If the equipment does not have adequate safety measures, the operator may be injured. In addition, the equipment needs to be able to detect abnormal conditions and stop operation in time to avoid damage to the equipment or other accidents.

[0008] 5. Adaptability and flexibility: Different materials and workpieces may require different nailing methods and parameters. Automatic nailing technology needs to have adaptability and flexibility to adapt to different needs. This may involve adjusting nailing force, speed, angle and other parameters to ensure optimal results in different situations.

[0009] Therefore, there is an urgent need for a long and short nail programmable automatic nailing device to solve the above problems. SUMMARY

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0027] The purpose of the present application is to provide a long-short nail programmable automatic nailing device to solve the problems in the prior art.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1:

[0030] This embodiment provides a programmable automatic nailing device with long and short nails, such as... Figures 1-4 As shown, the system includes a gantry frame 3. The top of the gantry frame 3 is equipped with a nail feeding mechanism, and below the nail feeding mechanism are a nail fixing mechanism and a nail clamping mechanism. Both the nail fixing mechanism and the nail clamping mechanism are connected to the gantry frame 3 through a guide mechanism.

[0031] Specifically, the nail feeding mechanism includes a short nail vibratory plate 101 and a long nail vibratory plate 102. Both the short nail vibratory plate 101 and the long nail vibratory plate 102 are connected to the first transport trough 1801. The first transport trough 1801 is connected to the second transport trough 1901 through a connector 1701. The second transport trough 1901 is provided with a nail-locking element 2001. The tail end of the nail-locking element 2001 is connected to the push rod of the electromagnet 2101. A funnel 201 is received below the nail-locking element 2001. The funnel 201 is connected to the nail-locking mechanism through a conduit.

[0032] Furthermore, both the first transport trough 1801 and the second transport trough 1901 are inclined downwards by 1° to ensure that the nail slides down smoothly.

[0033] Furthermore, the fixing mechanism includes an upper crossbeam 5, which is slidably mounted on the gantry frame 3 via a guide mechanism. The upper crossbeam 5 has a first cylinder 401 on both sides, which is connected to the fixing mechanism via a first push rod 601. The upper crossbeam 5 has a second cylinder 801 in the middle, which is connected to the fixing mechanism via a second push rod 901. The upper crossbeam 5 has a firing pin 1201 at the bottom.

[0034] Furthermore, the nailing mechanism includes a lower crossbeam 7, which has a nail inlet hole and a nail driving hole. The nail inlet hole is inclined and communicates with the guide tube, while the nail driving hole is vertical and corresponds to the position of the striking pin 1201. A nail box mold 1501 is provided below the nail driving hole. The upper part of the nail box mold 1501 is connected to the lower crossbeam 7 through a fixing pin 1401. Springs 1601 are provided on both sides of the nail box mold 1501.

[0035] Furthermore, the middle part of the card holder mold 1501 has a funnel-shaped structure.

[0036] Furthermore, the guiding mechanism includes a guide rail 1101, which is located on the inner side of the gantry 3. Both ends of the upper crossbeam 5 and the lower crossbeam 7 are provided with sliders 1001, which are slidably limited on the guide rail 1101.

[0037] The long and short nail programmable automatic nailing device provided by the application has the working principle that: first, the short nails and long nails are respectively poured into the short nail vibrating disc 101 and the long nail vibrating disc 102, the nails are sequentially transported into the conveying grooves through the vibration of the vibrating disc. The end of the conveying groove is provided with a nail clamping element and an electromagnet, the opening and closing of the nail clamping element are controlled by programming control of the electrification and power-off of the electromagnet. When the nail reaches in front of the nail clamping element, the electromagnet is electrified, so that the two nail clamping elements are opened, the nail enters the gap between the two nail clamping elements, the gap can only allow one nail to enter at a time, after one nail enters, the electromagnet is immediately powered off, so that the nail clamping element is closed, and the nail is dropped into the funnel below one by one through the repeated action. After the nailing work is completed, the electromagnet can be directly powered off through programming, the nail clamping element is closed, and the nail will not continue to drop into the funnel. As shown in Figure 1 Each conveying groove is inclined downward by 1°, which is more conducive to the smooth arrival of the nails at each discharge port. Because the diameter of the short nail is smaller than that of the long nail, the spacing between the conveying grooves connected to the short nail vibrating disc 101 on the other side is smaller than the spacing between the second conveying groove 1901 and the first conveying groove 1801, so as to ensure that the nails will not fall off the conveying groove. The nail feeding mechanism can also control the electrification and power-off of each electromagnet through programming, control the opening and closing of the nail clamping element on each discharge port, and realize flexible nail feeding according to the requirements of different working conditions.

[0038] Then, the lower cross beam 7 has 8 nailing holes and nail feeding holes, each nail feeding hole is connected with the funnel through a conduit, and the nail dropped into the funnel slides from the top to the tail of the conduit and enters the nail feeding hole of the lower cross beam 7. As shown in Figure 4As shown, when the nail just enters the nail box mold and is stuck, the position of the nailing mechanism is shown as position a in the figure, at this time the upper cross beam 5 and the lower cross beam 7 are located at the initial position. The whole device is installed on a workbench, the wooden tray to be processed is placed on the workbench plane below the lower cross beam 7, when the nail enters the nail box mold, the box mold is in the closed state due to the elastic force of the two side springs, at this time the head of the nail is just stuck, about half of the tail of the nail is exposed outside the lower surface of the lower cross beam 7, at this time the distance between the tail of the nail and the upper surface of the wooden tray is about 5mm, the tail of the nail has not contacted the wooden board. Next, the push rod in the pneumatic cylinder is driven by gas pressure to move, the two single-shaft stroke adjustable pneumatic cylinder push rods pull the upper cross beam 5 to move downward, at this time the two double-shaft pneumatic cylinders are not connected to the gas pressure, the lower cross beam 7 is not moved. When the top of the striker 1201 on the upper cross beam 5 just contacts the head of the nail, the double-shaft pneumatic cylinder is connected to the gas pressure, the upper cross beam 5 and the lower cross beam 7 move downward together, at this time the nail is pushed into the wooden board under the striker, until the lower cross beam 7 contacts the upper surface of the wooden tray, the lower cross beam 7 reaches the lower limit position b, at this time the part of the nail that is just exposed outside has been fixed into the wooden board, in this process the two cross beams move together, the upper cross beam 5 always stops against the nail head, preventing the nail from moving upward due to the resistance generated by the wooden board when the nail is fixed into the wooden board, and the nail body is limited by the nail box mold to ensure that the nail is fixed into the wooden board vertically. Next, the two single-shaft stroke adjustable pneumatic cylinder push rods continue to pull the upper cross beam 5 to move downward, the lower cross beam 7 is stopped by the wooden board, the position remains unchanged, the striker pushes open the nail box mold, the springs on both sides of the box mold are compressed, the nail box mold is opened, the striker will always push the nail until the nail is completely fixed into the wooden board about 2mm.

[0039] Finally, when the nail is fixed into the wooden board, the upper cross beam 5 and the lower cross beam 7 return to the initial position a under the drive of the pneumatic cylinder, preparing for the next nailing action. In the process of upward movement of the upper and lower cross beams, the striker will leave the nail box mold, at this time the springs on both sides of the box mold will push the rectangular block to reset, and the nail box mold is closed. The single nailing process of the product is as above, and the continuous nailing work can be completed by repeating the above process.

[0040] The long and short nail programmable automatic nailing device provided by the present application has the following advantages compared with the traditional nailing equipment:

[0041] 1. Nail selection and supply. Using traditional automatic nailing technology, the type and size of nails usually need to be manually replaced, which may cause downtime and reduce production efficiency during production.

[0042] The product has the automatic function of nail selection and supply. It can automatically select the appropriate type and size of nails according to different requirements and workpiece requirements. This automatic feature can improve production efficiency, reduce manual intervention, and at the same time ensure that the correct nails are used every time, avoiding the adverse effects caused by selecting the wrong nails.

[0043] 2. Verticality and consistency. Traditional automatic nailing techniques may face certain challenges in maintaining consistent accuracy, as slight variations in positioning and force during operation can occur.

[0044] This product employs reliable positioning technology. Through the core component of the nail box mold, it ensures that the nails are vertically positioned into the wood panel, achieving a more accurate nailing operation and maintaining consistency across multiple operations. This improvement in verticality and consistency can increase the quality and reliability of the product.

[0045] 3. Adaptability and flexibility. Different materials and workpieces may require different nailing methods and parameters. Traditional automatic nailing techniques may be limited in adaptability and flexibility.

[0046] This product has programmability and flexibility. It can adjust the force, speed, and other parameters of nailing according to different requirements and workpiece characteristics to achieve the best nailing effect. This adaptability and flexibility can meet diverse production needs, improve production efficiency and product quality.

[0047] In summary, the long-short nail programmable automatic nailing device has certain advantages by solving the technical problems of nail selection and supply, improving verticality and consistency, and enhancing adaptability and flexibility. It can improve production efficiency, reduce manual intervention, improve product quality, and adapt to different production needs.
