Description

Technical Field

[0001] The present invention relates to the field of pneumatic nail production and manufacturing, and particularly to an automatic packing device for pneumatic nails. Background Art

[0002] A pneumatic nail gun is also called a pneumatic nail driver. The pneumatic nail gun uses the air pressure generated by an air pump (air compressor) as the power source. The air pressure for a small gun is [4 - 6.5 Kg / cm² (Bar)], and the air pressure for a large nail gun is [5 - 8 Kg / cm² (Bar)]. The high-pressure gas drives the striker in the cylinder of the nail gun to perform a hammering motion, driving the collated nails in the collated nail clip into an object or shooting the collated nails out. The nails applied to this type of pneumatic nail gun are collectively called pneumatic nails.

[0003] Pneumatic nails are widely used in industries such as the decoration industry, machining, and material packaging. Due to the fast firing speed of the pneumatic nail gun, the consumption of nails is extremely large. Therefore, the number of nails packed in each box of finished pneumatic nails is relatively large. In the prior art, due to the relatively high requirements for the arrangement and packing of pneumatic nails, the packing and packaging of pneumatic nails are mostly achieved through manual packing. The large number of nails requires nail production enterprises to provide a large number of workers in the packing link, resulting in a waste of human resources. In addition, the packing quality and the number of packed items in manual packing often fluctuate. Especially after a large number of long-term packing operations, the fatigue of the operating workers accumulates to a certain extent, making it impossible to guarantee the packing efficiency, and resulting in low packing efficiency, seriously affecting the production efficiency of nail production enterprises and increasing production costs.

[0032] Preferably, the conveying roller group 6 is a non-powered roller group, and the packaging box is clamped and conveyed by the box clamping assembly 8. Embodiment

[0033] In practical applications, the packaging boxes folded into plate shapes are neatly arranged and stacked in the packaging box stacking assembly 1. By adjusting the screw assemblies, the displacement of the lower cardboard limiting plate 14 and the side cardboard limiting plate 19 of the cardboard box is adjusted respectively, so that the distance between the lower cardboard limiting plate 14 and the side cardboard limiting plate 19 of the cardboard box corresponds to the size of the plate-shaped packaging box, thereby achieving the purpose of fixing and placing the plate-shaped packaging box. At the same time, the positioning roller 17 and the lower cardboard limiting plate 14 above the outlet of the packaging box stacking assembly 1 buckle the plate-shaped packaging box in the packaging box stacking assembly 1, keeping it in a neatly stacked state waiting for use. The whole packaging box stacking assembly 1 is inclined towards the nail feeding guiding assembly 2, so that the plate-shaped packaging box can move closer to the nail feeding guiding assembly 2 by its own weight, achieving the purpose of automatic feeding.

[0034] The manipulator cylinder 51 on the picking manipulator 5 is enabled, driving the support arm 52 to make a back-and-forth swing. When the support arm 52 swings to the extreme position towards the packaging box stacking assembly 1, the suction cup 53 at the end of the support arm 52 adsorbs the first plate-shaped packaging box at the outlet of the packaging box stacking assembly 1. At this time, the manipulator cylinder 51 drives the support arm 52 to retract, and the suction cup 53 adsorbs the plate-shaped packaging box and overcomes the buckling damping of the positioning roller 17 and the lower cardboard limiting plate 14 to take out the first plate-shaped packaging box. Under the guiding action of the cardboard box guiding strip 21, the plate-shaped cardboard box falls into the nail feeding guiding assembly 2. At the same time, when the suction cup 53 guides the plate-shaped packaging box into the nail feeding guiding assembly 2, the plate-shaped packaging box is pulled into a box-shaped packaging box.

[0035] The box clamping assembly 8 stands by above the nail feeding guiding assembly 2 driven by the driving screw assembly 7. When the packaging box is placed in place, the clamping cylinder 83 drives the box clamping arm 82 to close and buckle on both sides of the packaging box. The locking buckle 84 behind the box clamping arm 82 is pushed forward by the locking cylinder and locks and positions the box clamping arm 82, keeping the packaging box in a box frame state.

[0036] The neatly stacked nails are placed and standby at the inlet end of the nail feeding guiding assembly 2. After the packaging box is locked and maintained in a box frame state by the pushing mechanism, the neatly stacked nails are pushed towards the packaging box. Under the action of the pushing force, the left and right feeding guiding plates 22 and the lower feeding guiding plate 23 on the nail feeding guiding assembly 2 move synchronously and open through the synchronous gear set 25, guiding the nails into the packaging box. After the nails are placed, the left and right feeding guiding plates 22 and the lower feeding guiding plate 23 retract and remain in a closed and retracted state under the action of the return spring 24.

[0037] After the gun nails are placed, the driving screw rod assembly 7 enables the driving box body clamping assembly 8 to drive the packing box to be conveyed forward at a uniform speed along the conveying roller group 6. When it reaches the designated position of the box body folding assembly 3, the first static box closing member 32 at the front end of the conveying direction closes the side plates of the carton at the front end. The folding driving cylinder 35 on the dynamic box closing assembly 31 at the rear end of the conveying direction pushes the driving arm 36 to rotate, closing the side plates of the carton at the front end. The packing box continues to be conveyed, and the second static box closing member 33 closes the upper and lower cardboard of the carton by two pairs of upper and lower guiding members.

[0038] The driving screw rod assembly 7 enables the driving box body clamping assembly 8 to continue conveying the packing box. The sealer 4 seals the folded packing box, completing a set of processes of starting pneumatic gun nail packing and sealing. The driving screw rod assembly 7 enables the driving box body clamping assembly 8 to reset and standby above the gun nail feeding guiding assembly 2, waiting for the next packing operation, and so on continuously.

[0039] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
