Background technology
Carton generally is folding sheet after manufacturing is finished, carton is shaped to be carton is strutted sequence of operations process for the three-dimensional shape that is suitable for the object vanning from the sheet rugosity.Send acting as of case apparatus that stacked set up box separated piecewise and send into carton shaping streamline.The case apparatus that send in the past comprises folded case baffle plate or divider, form folded case space between folded case baffle plate or the divider, the sheet carton overlays on the frame in the case space, the bottom in folded case space is provided with the carton pushing mechanism, when sending the case operation, the carton pushing mechanism moves back and forth, and the acting in conjunction by conveying roller, carton is gone out to fold the case space from the bottom push-and-pull of folded case space piecewise, finish the case work of sending, this case apparatus that send is during the carton of push-and-pull bottom, the frictional resistance that is subjected to is very big, send the live load of case apparatus big.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel case apparatus that send that is used for the carton shaping that more in the past sent the case load to reduce.For this reason, the utility model by the following technical solutions: it comprises the reciprocating carton pushing mechanism of being located at bottom, folded case space, and in the central region of bottom, folded case space, described carton pushing mechanism also is provided with reciprocating carton supporting plate or carriage.Owing to adopt the technical solution of the utility model, the sheet carton overlays reciprocating carton supporting plate or carriage and along with supporting plate or carriage move together, can greatly reduce the suffered frictional force of cardboard, reduce to send the case load, and reduce the impaired possibility of carton.
On the basis of adopting technique scheme, the utility model also can adopt following further technical scheme simultaneously:
Described carton pushing mechanism is provided with the carton pushing block that is connected with described supporting plate or carriage.In bottom, folded case space, described carton pushing mechanism also can be provided with liftable sucker down.
The middle part of described supporting plate has the step of protrusion.
It is provided with the initial bit front and back governor motion of carton pushing mechanism.
The reciprocating motion driving mechanism of carton pushing mechanism is connected with supporting plate or carriage.
The specific embodiment
With reference to accompanying drawing.The utility model comprises the reciprocating carton pushing mechanism of being located at bottom, folded case space, and in the central region of bottom, folded case space, described carton pushing mechanism also is provided with reciprocating carton supporting plate 2.Described supporting plate also can be replaced by carriage.
In the present embodiment, the carton pushing mechanism comprises the carton pushing block 22 that is connected with described supporting plate.In bottom, folded case space, described carton pushing mechanism also can be provided with liftable sucker 1 down.Drawing reference numeral 11 is the lift cylinder of following sucker.By the synergy of their carton pushing blocks, following sucker, supporting plate, it is stronger that cardboard is promoted, and resistance is also littler, further reduces the impaired possibility of carton.
In the present embodiment, the middle part of described supporting plate 2 has the step 21 of protrusion.Like this, more help the part setting and the layout of carton pushing mechanism, make more reasonable structure, described down sucker 1 and carton pushing block 22 are located on the supporting plate outside the boss both sides.
In the present embodiment, described carton pushing mechanism adopts cylinder 23 as reciprocating driving mechanism, and like this, structure, control are more simple.Described cylinder 23 is connected with supporting plate, to move back and forth driving mechanism can also be cam mechanism, the transmission mechanism of cranking arm, by chain or belt gear, the oil cylinder etc. of driven by motor.
Present embodiment also is provided with the initial bit front and back governor motion of carton pushing mechanism.Drawing reference numeral 6 is adjustment seat, by the cooperation of screw rod and nut, rotates handgrip 61, can be in the position of sending case direction adjusted adjustment seat 6, and cylinder 23 is installed on the adjustment seat 6, also is provided with the slide rail 62 of supporting plate on the adjustment seat 6, and supporting plate is supported on the slide rail.Like this, by regulating adjustment seat 6, the initial bit that can regulate the carton pushing mechanism is to adapt to the carton of different sizes.
Drawing reference numeral 3 for send case apparatus about folded case baffle plate, about be the folded case space of sheet carton between folded case baffle plate.Drawing reference numeral 4 is for sending the backboard of case apparatus.Drawing reference numeral 5 is a conveying roller.When sending case, the bottom carton is supported on the supporting plate 2, following sucker by cylinder jack-up and hold the bottom carton, under the effect of reciprocating mechanism, supporting plate reaches down, and sucker, pushing block travel forward together, carton is pushed conveying roller, following sucker is removed the absorption to the bottom carton, the carton output that to fold case space bottom by conveying roller will be folded the case space again, finish the case work of sending, and this moment, lift cylinder 11 is fallen sucker, under the drive of reciprocating mechanism, supporting plate and down sucker, pushing block retreat and carry out the next one to starting point and send the case action.
