Not having intermittently, cardboard switches feedway
Technical field
The utility model relates to the conveying technology of cardboard in packing, the printing production line, and especially a kind of nothing intermittently cardboard is switched feedway.
Background technology
In the cardboard course of conveying of packing, printing production line, the cardboard model of being carried needs conversion according to processing request, the mode that the cardboard feedway of prior art adopts when changing the cardboard model is: in the time of will being replaced by another model cardboard after carrying certain model cardboard, when last branch by load-transfer device of certain model cardboard is piled up neatly roller, divide the buttress roller to lift, stop the cardboard of another model to pass through, and another model cardboard heap before minute buttress roller is piled up, when last breaks away from load-transfer device fully until certain model cardboard, divide the buttress roller to put down, another model cardboard recovers normal and carries.The problem that this kind mode of movement exists is: easily produce the whole phenomenon of pile in heap pile process, produce crookedly during conveying, impact to later process, for this reason, need to add manual sorting, work capacity is big, speed is slow, is forced to when serious interrupt carrying, and causes production line downtime.
Summary of the invention
The purpose of this utility model is that a kind of nothing cardboard at intermittence that provides at the deficiencies in the prior art switches feedway, and it does not have intermittently the switching of cardboard model, has improved the cardboard transport efficiency, has reduced productive costs.
The concrete technical scheme that realizes the utility model purpose is:
A kind of nothing intermittently cardboard is switched feedway, it comprises fixed mount, trolley, depiler structure, load-transfer device, described fixed mount both sides are provided with shrouding, two ends are provided with driving rolls, parallelly between two shroudings be provided with four return idlers with two driving rollss, two shroudings are provided with pinion stand, and two gears are housed on the pinion stand; Trolley is located on two gears; The depiler structure is located at the trolley middle part; Load-transfer device is two, and a load-transfer device and a driving rolls, two return idlers, trolley constitute closed loop, another load-transfer device and a driving rolls, two return idlers, trolley formation closed loop.
Described trolley comprises cant board, tooth bar and four rolling, and cant board is two and is symmetrical arranged that tooth bar is located on the vertical plates on both sides base, and four rolling is located between the vertical plates on both sides.
Described depiler structure is made up of cylinder, branch buttress roller, and cylinder is fixed on the cant board, divides the buttress roller to be located on the cylinder.
Described two driving rollss and a gear connect motor respectively.
The utility model need not artificial letter sorting, arrangement in the cardboard course of conveying, eliminated the manufacturing line disruption that produces when changing because of cardboard effectively, has improved the cardboard transport efficiency, has reduced productive costs.

The specific embodiment
Consult Fig. 1, Fig. 2, the utility model comprises fixed mount 1, trolley 2, depiler structure 3, load-transfer device, fixed mount 1 both sides are provided with shrouding 11, two ends are provided with driving rolls 12,13, between two shroudings 11 with driving rolls 12, the 13 parallel return idlers 4,5,6,7 that are provided with, two shroudings 11 are provided with pinion stand 18, and gear 14,19 is housed on the pinion stand 18; Trolley 2 is located on the gear 14,19; Depiler structure 3 is located at trolley 2 middle parts; Load-transfer device is two 16,17, and load-transfer device 16 constitutes closed loop with driving rolls 12, return idler 4,5, trolley 2, and load-transfer device 17 constitutes closed loop with driving rolls 13, return idler 6,7, trolley 2; Trolley 2 comprises cant board 21, tooth bar 24, roller 25,26,27,28, and cant board 21 is two and is symmetrical arranged that tooth bar 24 is located on vertical plates on both sides 21 bases, and roller 25,26,27,28 is located between the vertical plates on both sides 21; Depiler structure 3 is made up of cylinder 31, branch buttress roller 32, and cylinder 31 is fixed on the cant board 21, divides buttress roller 32 to be located on the cylinder 31; Driving rolls 12, driving rolls 13, gear 19 connect motor respectively.
The utility model is work like this: start driving rolls 12,13, drive load-transfer device 16 and rotate around driving rolls 12, return idler 4,5,25,26 annulars, load-transfer device 17 rotates around driving rolls 13, return idler 6,7,27,28 annulars; In the normal transportation process, cardboard is positioned on the load-transfer device 17 and is delivered to next procedure by driving rolls 13 to driving rolls 12 directions.When needing to change the different model cardboard on the load-transfer device 17, control system is sent instruction, starting driven wheel 19 is moved to driving rolls 12 directions by driving rolls 13 by tooth bar 24 drive trolleys 2, the cardboard of changing keeps normal and carries on load-transfer device 17, when last base board enters load-transfer device 16, opening cylinder 31 will divide buttress roller 32 to lift, stop the cardboard of changing to pass through, because the effect of trolley 2, the cardboard of changing moves on load-transfer device 17, when last base board breaks away from load-transfer device 16 fully, cylinder 31 will divide buttress roller 32 to put down, and trolley 2 is return initial position, and stop motion, the cardboard of changing enters normal feed status, and is reciprocal according to this.
