Description

Technical Field

[0001] The present invention relates to a method for feeding double-sided flat fastener nails, and more particularly to a method in which two ends of a feeding tube having a plurality of limiting parts inside are respectively connected to a feeding mechanism and a rivet pulling device, so that a plurality of pulling caps and nail caps will not have position deviations during the transportation process, and are then smoothly transported to the rivet pulling device for use, so as to prevent the rivets and rivets from getting stuck after use and save the use of pull rods to meet the purpose of energy saving and carbon reduction. Background Art

[0002] The conventional double-sided flat fastener can be found in U.S. Pat. No. US8328483. The double-sided flat fastener is inserted into the fixing holes of two workpieces through a pull nail, and the nail head of the pull nail is set in the fixing hole. When the rod of the pull nail is pulled by a preset nail gun, the rod body extending from one side of the head hits the inside of the nail head through the bottom side of the head, thereby causing the nail head to deform to fix the two workpieces and form a double-sided flat effect with flat sides.

[0003] However, the use of the above-mentioned rivets and rivets will leave a large number of rivet rods on site, and the rivet rods account for 90% of the total weight. Therefore, the use of rivets and rivets will generate a large amount of waste, which invisibly causes a large amount of material waste and cost loss.

[0004] In view of this, the relevant industry has made improvements on this point and further developed a rodless rivet gun. In order to load the rivet cap using the rivet cap clamping mechanism, the same pull rod is reused to cooperate with the use of the rodless rivet cap to connect the rivet cap to the object, thereby achieving the effect of saving a large amount of waste rivets and rivets.

[0005] However, if there is any excess vibration or shaking during the process of transporting the rodless nail nut to the nail gun, the rodless nail nut may easily deviate from its position, causing the nail gun to become stuck or jammed after being fed to the nail gun, making it temporarily unusable. This is the key issue that needs to be studied and improved urgently by those engaged in this industry. Summary of the invention

[0006] Therefore, in view of the above problems and deficiencies, the main purpose of the present invention is to provide a double-sided flat fastener feeding method.

[0007] The present invention provides a double-sided flat fastener feeding method, comprising a feeding mechanism and a nail pulling device, wherein a feeding pipe for conveying a plurality of workpieces is provided between the feeding mechanism and the nail pulling device, and the method is implemented according to the following steps:

[0008] (A01) one end of the feeding pipe is connected to the feeding part of the feeding mechanism, and the other end of the feeding pipe is connected to the rivet pulling device;

[0009] (A02) placing a plurality of workpieces into a feeding device of the feeding mechanism, and sequentially conveying the plurality of workpieces to a feeding section via a feeding belt of the feeding device;

[0010] (A03) the plurality of workpieces are fed into the rivet pulling device via the feeding tube connected to one side of the feeding portion, and the plurality of workpieces are limited by the plurality of limiting portions in the feeding tube so as to maintain displacement in the same direction to the rivet pulling device;

[0011] (A04) The plurality of workpieces are then pushed into position by a pushing mechanism in the rivet pulling device, so that the rod clamping mechanism in the rivet pulling device can deform by operating the rod to penetrate the plurality of workpieces, and the deformed workpieces can be pushed out through a gun nozzle connected to one side and positioned on a plate to be processed for fixation;

[0012] (A05) can complete the feeding of double-sided flat fasteners.

[0013] Wherein, in the step (A02), a pushing device is provided on a side of the feed part adjacent to the feed belt, and an air inlet is provided on a side of the feed part away from the feed belt, and one side of the air inlet is connected to a blowing device.

[0015] Wherein, the pushing device is a pneumatic cylinder or a hydraulic cylinder.

[0016] The plurality of workpieces are rivet caps or rivet caps.

[0017] Wherein, the feeding tube is made of soft material.

[0018] The present invention connects the two ends of the feeding tube with multiple limiting parts inside to the feeding mechanism and the rivet pulling device respectively, so that the multiple pull caps and nail caps will not have position deviation during the transportation process, and are smoothly transported to the rivet pulling device for use. The pushing mechanism inside the rivet pulling device pushes the multiple pull caps and nail caps to a position so that the rod clamping mechanism operates the rod body to cooperate with the use of the pull caps and nail caps, so as to prevent the rivets and rivets from getting stuck after use and save the use of the pull rod to meet the purpose of energy saving and carbon reduction.

DETAILED DESCRIPTION

[0025] See also Figures 1 to 4 The figures are respectively a top view of a feeding mechanism of a double-sided flat fastener feeding device, a cross-sectional view of a feeding pipe, a side view of a rivet pulling device and a schematic diagram of a clamping nozzle. The present invention provides a double-sided flat fastener feeding method, which mainly includes a feeding mechanism 1, a rivet pulling device 2 and a feeding pipe 3 arranged between the feeding mechanism 1 and the rivet pulling device 2 to transport a plurality of workpieces 4. The connection relationship of the aforementioned components is as follows:

[0026] The feeding mechanism 1 includes a feeding device 11, a pushing device 12 and a blowing device 13, and the feeding device 11 is provided with an arranging portion 111 with a accommodating groove 1110, and one side of the arranging portion 111 is provided with a feeding belt 1111 connected to the accommodating groove 1110, and a feeding portion 1112 is connected to the end of the feeding belt 1111, and an air intake portion 1113 is provided on the side of the feeding portion 1112 away from the feeding belt 1111, and a pushing portion 122 connected to the side of the feeding portion 1112 adjacent to the feeding belt 1111 is provided at the front end of the main body 121 of the pushing device 12, and an air supply pipe 132 connected to the air intake portion 1113 is provided on one side of the jet device 131 of the blowing device 13.

[0027] The nail pulling device 2 has a nail gun body 21, and a feed port 20 is provided on one side of the nail gun body 21 for connecting one side of the feed pipe 3. A gun nozzle 211 extends downward from the nail gun body 21, and at least two clamping nozzles 212 are provided around the gun nozzle 211 to cover the gun nozzle 211 for protection.

[0028] The feeding tube 3 is made of soft material, and its other end which is not connected to the feeding port 20 is connected to the feeding portion 1112 and aligned with one side of the air inlet portion 1113. The feeding tube 3 has a feeding channel 30 therein, and a plurality of limiting portions 301 are provided in the feeding channel 30 to limit the feeding direction of the plurality of workpieces 4.

[0029] In addition, the conventional double-sided flat fastener is inserted into the fixing holes of the two workpieces through a pull nail, and the nail cap of the pull nail is set in the fixing hole. When the rod body extending from the head side of the pull rod of the pull nail is pulled by a preset nail gun, the bottom side of the head hits the inside of the nail cap, thereby causing the nail cap to deform to fix the two workpieces and form a double-sided flat effect with smooth sides. However, after the head hits, the rod body breaks and is pulled out of the nail cap, resulting in about 90% of the weight of the pull nail being waste after use, which invisibly causes a large amount of material waste and cost loss, and does not meet the purpose of energy saving and carbon reduction.

[0030] Furthermore, in actual application of the present invention, the plurality of workpieces 4 are placed in the receiving groove 1110 of the arranging portion 111 of the feeding device 11, and the plurality of workpieces 4 may be rivet caps or rivet caps, and the plurality of workpieces 4 are arranged in the correct direction by the arranging portion 111, and the plurality of workpieces 4 are sequentially transported to the feeding belt 1111 connected to the receiving groove 1110 on one side of the arranging portion 111 by the feeding belt 1111 connected to the other end of the feeding belt 1111. The workpiece 4 input into the feeding part 1112 is pushed by the pushing part 122 connected to the front end of the main body 121 of the pushing device 12, and then moves to the front of the air inlet part 1113 while keeping the direction unchanged, and the air pressure is input to the air inlet part 1113 through the air supply pipe 132 by the jet device 131 of the blowing device 13, so as to blow the workpiece 4 in front of the air inlet part 1113 into the feeding part 1112 connected to one side. The workpiece 4 is placed in the feeding tube 3 and enters the feeding port 20 of the rivet pulling device 2 along the feeding channel 30 in the feeding tube 3. The workpiece 4 is limited by the plurality of limiting parts 301 inside the feeding channel 30 during the movement of the feeding channel 30 and keeps its direction unchanged, so that the workpiece 4 enters the rivet pulling device 2 in the correct direction, and is then pushed and positioned by the pushing mechanism (not shown) in the rivet pulling device 2, so that the rod clamping mechanism (not shown) in the rivet pulling device 2 can penetrate the plurality of workpieces 4 through the operating rod (not shown) and thus deform, so that the deformed workpiece 4 can be pushed out through the gun nozzle 211 and positioned on the plate to be processed (not shown) for fixation, so as to achieve the purpose of preventing a large number of workpieces 4 from changing direction due to shaking or other reasons during transportation, causing the plurality of workpieces 4 to be blocked and unable to be used.

[0031] Furthermore, the pushing device mentioned above can be a pneumatic cylinder, a hydraulic cylinder or other power equipment.

[0032] Furthermore, by repeatedly using the rod in the rivet pulling device 2 to perform the deformation operation of the plurality of workpieces 4, the disposable use of traditional rivet pulling rods is eliminated, the cost of rivet and rivet production can be saved, and the waste of resources can be reduced to meet the environmental protection, energy saving and carbon reduction goals promoted by the government in recent years.
