Since the loading strip 700 loaded with the tips 710 is moved away from the tip loading unit 300, since the circular edge 711 at the top end of the tips 710 is circular, when the tips 710 on the loading strip 700 are misaligned with the tips 710 on the skewing strips 320, the tips 710 on the skewing strips 320 will follow the circular arc of the circular edge 711 by a certain distance and partially fit into the gap between the circular edge 711 of the tips 710 on the loading strip 700 and the loading chute 701, which may cause resistance to the movement of the loading strip 700 and may also cause the tips 710 to be deformed. The flaps 341 may be lowered after the loading bar 700 has been loaded to block subsequent tips 710 from continuing to move toward the loading bar 700, thereby eliminating resistance caused by such interference. In order to improve the stability and precision of the lifting of the blocking member 340, the front and rear sides of the bottom of the blocking member 340 are provided with downwardly extending guide posts 342, the inclined slide bars 320 arranged at the front end and the rear end are provided with guide holes for the insertion of the guide posts 342, and the stable lifting is realized through the matching of the guide holes and the guide posts 342.
In some embodiments of the present invention, the attachment plate 330 is drivingly connected to the blocking member 340 via a pulley block 350 and a connecting cord 360; when the attachment plate 330 is attached to the inclined sliding strip 320, the blocking piece 341 and the supporting portion 321 have a gap for the circular edge 711 to pass through; as the attachment plate 330 rotates outward away from the diagonal slide 320, the stop 341 moves downward to block the circular rim 711 from moving toward the load bar transport line 600. Synchronous cooperation of the attachment plate 330 and the blocking member 340 is achieved by the interlocking action of the two. Specifically, the bottom of the hinged end of the attaching plate 330 extends downwards to form a wrapping post 331, the bottom of the wrapping post 331 is provided with a limiting round head 332, one end of a connecting rope 360 is connected to the wrapping post 331, the middle of the connecting rope is wound on the pulley block 350, and the other end of the connecting rope is fixedly connected with the blocking piece 340.
In a further embodiment of the present invention, the bottom of the movable end of the attachment plate 330 is provided with a connecting block 333, the connecting block 333 is provided with a first hook 334, the bottom of the diagonal slide 320 is provided with a second hook 323, the pre-tightening member is a return spring 370 that is hung between the first hook 334 and the second hook 323, the attachment plate 330 can be tightly attached to the diagonal slide 320 through the return spring 370, and can be pulled up against the gravity of the blocking member 340.
In some embodiments of the present invention, since the notch is formed at the left side of the middle of the carrier strip conveying line 600 corresponding to the position of the gun head loader 300, in order to obtain better support when the carrier strip 700 passes through the position of the gun head loader 300, the bottom of the inclined slide 320 extends horizontally towards the carrier strip conveying line 600 to form a support 322 for supporting the carrier strip 700.
In some embodiments of the present invention, the turning device 400 includes a dwell bracket 410 and a push plate 420, the dwell bracket 410 being located at the output end (front end) of the carrier strip transport line 600 for receiving the carrier strips 700 output from the carrier strip transport line 600; the pusher plate 420 is used to push the carrier strip 700 on the dwell frame 410 to move in its width direction (left-right horizontal direction) to enter the transfer device 500. The push plate 420 is connected to a push driving mechanism 421, and the push driving mechanism 421 may be a driving mechanism with a telescopic function, such as a telescopic motor and an air cylinder.
Referring to fig. 10, in some embodiments of the present invention, the stay frame 410 includes a bottom plate and support bars 411 erected on the bottom plate, the support bars 411 are arranged in a plurality at intervals in a front-rear direction and in two rows at intervals in a left-right direction to support the carrier bars 700, the support bars 411 are arranged in the left-right direction and in the front-rear direction at intervals to provide a space for the tips 710 of the carrier bars 700 to pass through, and a baffle plate 412 is disposed at a front side of the bottom plate to block the carrier bars 700 from being discharged out of the stay frame 410 by the carrier bar conveyor line 600.
In some embodiments of the present invention, a transfer belt 430 is disposed between the transfer device 500 and the parking stand 410, and two transfer belts 430 are disposed at a distance in the front-rear direction. The transfer belt 430 accelerates the carrier strip 700 within the transfer device 500 a distance into the belt 110. The transfer device 500 is two inclined plates arranged at intervals in the front-rear direction, one end of each inclined plate facing the corresponding transfer belt 430 is provided with a receiving part 510 extending between the two transfer belts 430 so as to smoothly receive the loading strips 700, the other end of each inclined plate extends into the box body 100, specifically, each inclined plate enters the box body 100 from the corresponding introduction port 103, the back sides of the parts of the two inclined plates extending into the box body 100 are provided with top plates 530, and the top plates 530 are used for ejecting the hinged plates 160 to prevent the hinged plates 160 from blocking the loading strips 700 from entering the box body 100. In addition, the side plate 520 is disposed on the opposite side of the two inclined plates to prevent the loading bar 700 from falling.
In some embodiments of the present invention, in order to reduce the sliding resistance of the loading bar 700, the surfaces of the apparatus that slide relative to the loading bar 700 are both smooth surfaces, or the surfaces that slide relative to the loading bar 700 are provided with structures such as balls and pulleys, so as to convert the sliding friction into rolling friction, reduce the friction resistance, and enable the loading bar 700 to be better conveyed, or the two end surfaces and the bottom surface of the loading bar 700 in the length direction can be provided with structures such as balls and pulleys, so as to achieve the effect of reducing friction.
