Film promotes transporter
Technical field
The present invention relates to a kind of feedway, specifically, is that a kind of film promotes transporter.
Background technology
At present, for the production of the film of tire, after extrusion, need first to dry on airing machine, then deliver on conveyer, the process of film from airing machine to conveyer generally needs manual hand manipulation to complete, degree of automation is low, in course of conveying, the safety factor of workman is low, and easily meet accident injury accident, and work efficiency is also low.
In order to solve the problem, at first patent " a kind of crawl conveying arrangement " (application number: 201320443559.2) propose one manually alternative, carry out the device of film transport, but it still exists more deficiency.Owing to utilizing the lifting of air cylinder driven jaw, the lifting of jaw is not steady, and in lifting process, vibration is large, when especially cylinder runs to end of travel.Jaw pinches film by two jaws close, and jaw is to the fixing of film and built on the sand, when there is vibration in lifting process, film very easily comes off from jaw.Although installed guide rod, can only guide the general direction of jaw lifting, but two jaw up and down balance systems can not have been ensured, cannot ensure that two jaws are elevated to sustained height position.
Summary of the invention
The present invention is directed to the deficiency that current crawl conveying arrangement exists, devise a kind of new film and promote transporter.

Detailed description of the invention
Film of the present invention promotes transporter, as shown in Figures 1 to 3, comprise the crane 1 turned forward, crane 1 is provided with liftable slide unit 2, the both sides of crane 1 can arrange line slideway or line channel, and slide unit 2 both sides are slidably mounted on line slideway or line channel, due to line slideway or line channel along with crane 1 turns forward, thus in the process that slide unit 2 is elevated, also can have certain movement by fore-and-aft direction, film is moved to front upper place from lower rear.
Slide unit 2 is provided with grabbing device 3, crane 1 is also provided with elevating screw 4 and servomotor 5, the screw rod 6 of elevating screw 4 is parallel with the direction that slide unit 2 is elevated, namely parallel with line slideway or line channel, screw rod 6 is driven by servomotor 5 and rotates, and the nut 7 of elevating screw 4 is fixed on slide unit 2.
Grabbing device 3 comprises pedestal 9, base plate 10 and claw-plate 11, pedestal 9 is fixed on crane 1, the cross-sectional plane of base plate 10 is the V-arrangement that Open Side Down, claw-plate 11 is arranged on both sides before and after base plate 10, multiple pawl toe 21 can be provided with inside claw-plate 11, and base plate 10 also can be provided with the pawl hole 22 that pawl toe 21 can be made to insert thereupon, on pedestal 9, left and right is provided with Liang Zu bindiny mechanism 12.
Bindiny mechanism 12 comprises two side plates 13 that left and right is arranged, side plate 13 top is fixed on pedestal 9, between two side plates 13 of bindiny mechanism 12, jointed shaft 14 is installed, claw-plate 11 is all provided with multiple pawl arm 15, pawl arm 15 one end is connected with claw-plate 11, the other end is hinged on corresponding jointed shaft 14, be positioned at bottom the side plate 13 outside bindiny mechanism 12 and be all connected with base plate 10, leave space bottom side plate 13 inside bindiny mechanism 12 and between base plate 10, bindiny mechanism 12 is provided with driver train 16.
Driver train 16 comprises cylinder 17, slide-bar 18, slide-bar 18 two ends are arranged in the vertical chute 19 arranged of corresponding side plate 13 respectively, cylinder 17 to be fixed on pedestal 9 and push-and-pull slide-bar 18, make it be elevated, multiple pipe link 20 is installed between slide-bar 18 and each claw-plate 11, pipe link 20 one end is hinged on slide-bar 18, and the other end is hinged on the pawl arm 15 of corresponding claw-plate 11.
Between slide unit 2 and crane 1, elevation synchro drive 8 is also installed, elevation synchro drive 8 comprises the rotatable rotating shaft 23 being arranged on crane 1 top, in rotating shaft 23, left and right is symmetrically installed with sprocket wheel 24, each sprocket wheel 24 is equipped with chain 25, chain 25 one end is connected with crane 1, and the other end is connected with slide unit 2.Because rotating shaft 23 is horizontally disposed with, sprocket wheel 24 is symmetrical arranged, and chain 25 one end is all connected on fixed crane 1, and when slide unit 2 is elevated, the change in location of chain 25 other end is identical, thus makes the slide unit both sides synchronization lifting that is attached thereto.
In use, servomotor 5 is by elevating screw 4, slide unit 2 is driven to drop to lower, the piston rod of cylinder 17 is retracted, and make slide-bar 18 rise to extreme higher position, the slide-bar 18 of rising is by pulling pipe link 20, also pawl arm 15 has been pulled, two claw-plates 11 are lifted, open-shaped state, between claw-plate 11 and base plate 10, occur the space of a horizontal direction.
Be positioned at the airing machine of the back lower place, the front end of film is sent in this space between claw-plate 11 and base plate 10, piston rod is released by cylinder 17, slide-bar 18 moves down, promote pipe link 20, lower pressing claw arm 15, claw-plate 11 is all fallen, in closure state, film is clamped between claw-plate 11 and base plate 10, because two claw-plates 11 extrude former and later two upper surfaces of base plate 10 respectively, the cross-sectional plane of film front end is also clamped forming V-shape, if claw-plate 11 has installed pawl toe 21, pawl toe 21 will pierce through film, more firmly be fixed by film.
After film clamping, servomotor 5 is by elevating screw 4, and drive slide unit 2 to be raised to eminence, then control cylinder 17, retracted by piston rod, two claw-plates 11 open, thus unclamp film, film front end is delivered to and is positioned on the conveyer of front upper place.
