Below with reference to Fig. 1 to 6 summarily and consider that it is described the glued board unit mahine 1 according to first structure functionally.For better diagram, just partly show glued board unit mahine 1 here.Glued board unit mahine 1 comprises that in known manner one has the transmitting device of bottom chain 19 and top chain 21.Bottom chain 19 is driven by axle 14 and gear 20a, 20b on the direction of arrow (Fig. 1).Top chain 21 is driven by axle 12 and

gear

22a, 22b on the direction of arrow (Fig. 1).Between two

chains

19,21, transmit two gummed laths side by side in known manner at least to the heater (not shown), so that these two gummed laths interconnect.

Glued board unit mahine 1 also comprises an input equipment 2, and it at length illustrates in Fig. 6 at Fig. 4.Input equipment 2 comprise two parts stop device 3, it is made of first stop element 4 and second stop element 7, they contact at contact point K.Can see clearly that from Fig. 4 first stop element 4 comprises that a roller 5 and an operating element 6, the second stop elements 7 comprise an armed lever 8 and an operating element 9.First stop element 4 can be in movement in vertical direction, and second stop element 7 can be around swing swivel point S swing.Armed lever 8 has one and favours the surperficial 8a that glues together lath transport plane or transmission direction X, and it is configured to U-shaped (Fig. 6) basically.

In addition, input equipment 2 comprise one have around the belt driver of driving-belt 10, and be bearing in first deflecting roller 11 on the axle 12 and be bearing in second deflecting roller 13 on the axle 14.Belt driver is by common axle 14 and second deflecting roller 13 of gear 20a, 20b, to be driven with the same speed of bottom chain 19.

Input equipment 2 also comprises an input area 15, it especially in Fig. 3 as can be seen, and be arranged on and the contiguous place of first directive wheel 11.Input area 15 comprises the substrate that does not illustrate among the figure, and gummed lath 16 can be placed on this above substrate.18, two gummeds of one dividing plate lath 16 has been installed on substrate can be placed in the mode of Fig. 3 by this dividing plate.On this external input area 15 two wheel for inputting 17a, 17b have been installed, wherein a wheel for inputting is installed in dividing plate 18 the right or the left side separately.As shown in Figure 2, two wheel for inputting 17a, 17b install (about 5 ° to 10 °) slightly obliquely with respect to dividing plate 18, and when pushing gummed lath 16, the gummed lath is transfused to the direction that

wheel

17a, 17b are pressed to dividing plate 18 respectively like this.Because their self gravity, wheel for inputting 17a, 17b apply predetermined power to gummed lath 16.It should be noted that in order to support the thrust of wheel for inputting 17a, 17b, can additionally increase spring force, hydraulic coupling or aerodynamic force.

Function at this input equipment 2 is as follows: as shown in Figure 1, the exit of stop device 3 between first stop element 4 and second stop element 7 constituted a backstop of shrinking gradually.Shown in Fig. 2 and 3, when two will its side to edge fit on the gummed lath 16 that is pasted together be placed into and by the operator with hand when direction X pushes, two wheel for inputting 17a, 17b reciprocally move two gummed laths 16.When gummed lath 16 further pushed, they met the inclined plane 8a of armed lever 8, and then by a little upwards guiding.

As shown in Figure 1, stop device 3 has formed a backstop of shrinking gradually in its original position, this backstop is made up of the housing department section and the inclined plane 8a of roller 5, so that not only recline there, and be easy to be clipped between first stop element 4 and second stop element 7 at two gummed laths of stop device 3 places butt joint.The stop dog position that arrives or by operator's identification perhaps is provided with a sensor, such as a grating or detecting sensor, and the stop dog positions of two gummeds of its identification laths 16.Next step by the operator manually, perhaps by to the identification of stop dog position and automatically by means of operating element 9 make second retainer 7 around pivot S to lower swing.Like this, second stop element 7 just be arranged in driving-belt 10 below, promptly accurately below the top set of driving-belt.Between the roller 5 of first stop element 4 and armed lever 8, just formed a passage like this, thereby two gummed laths are contacted with lasting driven driving-belt 10.Gravity at the operating element 6 of this first stop element 4 and first stop element 4 is pressed on the driving-belt 10 gummed lath 16, and such two gummed laths 16 can be imported equably by means of driving-belt 10.

As shown in Figures 2 and 3, belt driver is installed between gear 20a, the 20b of bottom chain 19, makes by belt driver, can be input between bottom and the

top chain

19,21 at the gummed lath 16 that is transfused on the transmission direction X.Because belt driver is identical with the speed of

chain

19,21, so two gummed lath invariant position ground continues to be transferred to heater by the transmitting device of glued board unit mahine, and two abutting edges that glue together laths 16 are bonded together.

Special in Fig. 3 and shown in Figure 6, the inclined plane 8a of armed lever 8 has substantially and is the shape of U-shaped, thereby free leg is arranged in a side of the driving-belt 10 of belt driver.Can realize like this armed lever 8 around axis of oscillation 10 to lower swing.The width of the roller 5 of first stop element 4 is greater than the width of driving-belt 10 in addition, and roller 5 to small part is located in the zone of U-shaped leg of inclined plane 8a of armed lever 8 like this.The stop device 3 of input equipment 2 is to be provided with like this in the driving-belt conveyer, and promptly backstop 3 is at the summit R that departs from the belt driver on input area in the transmission direction 15 in the transmission direction slightly.Or rather, especially as shown in Figure 4, the stop dog position of backstop 3 (contact point K) is following selected: this stop dog position is positioned at a plane vertical with transmission direction X, and this plane is positioned at a straight line left side of passing axle 12 the rotation of first deflecting roller 11 and roller 5 in Fig. 4.Can guarantee that like this after armed lever 8 swings, gummed lath 16 abuts on the driving-belt 10 with predetermined length, thereby and can be transmitted by means of the transmitting device direction of belt driver towards machine 1 reliably.

When two gummed laths 16 that are transfused to fully by after the backstop 3, armed lever 8 by means of by for example can be pneumatic or the operating element 9 that drives of surging come back to original position among Fig. 1 or Fig. 4.At gummed lath 16 when having passed through stop device 3, this can or manually be carried out by the operator, is perhaps detected by sensor.Thus in this input equipment, and then pass and after stop device 3 resets, import two new gummed laths 16 immediately again and continue transmission by belt driver at two gummed laths 16.In this way, make glued board compared with prior art pitch time greatly shorten.Because belt driver is driven together by the transmitting device of glued board unit mahine 1, so just no longer need to be used for the individual drive or the expensive clutch of input equipment 2.The manufacturing cost of input equipment can significantly reduce like this.The structure space of glued board unit mahine has also reduced in this way in addition.

The driving-belt 10 of belt driver can use cingulum, such as the cingulum that is made of plastics.Can stipulate that in addition continue transmission in case the gummed lath 16 that is transfused to is transmitted

chain

19,21, first stop element 4 just moves upward, be used for making frictional resistance when transmission gummed lath, to keep as much as possible little and do not hinder gummed lath input chain.Can also prevent from like this to glue together and occur stress and projection on the lath.Be noted that further the sensor that detects the stop dog position of gummed lath 16 on backstop 3 also can be used to detect the trailing edge that glues together lath 16 and when pass through this sensor, so that make stop device 3 come back to its original position subsequently.

Next in conjunction with the glued board unit mahine 1 of Fig. 7 to 10 description according to second kind of structure.Part identical or identical function is used with Reference numeral same in first kind of structure described and is represented.

Different with first kind of structure is, according to the input equipment 2 of second kind of structure armed lever is not set.The backstop 3 of second kind of structure is made up of first stop element 4 and second stop element 27.Second stop element 27 is one to be essentially the element 28 of U-shaped, respectively has an inclined plane 28a on two leg.Inclined plane 28a is still with respect to transmission direction X inclination (referring to Fig. 7).Second stop element 27 comprises an operating element 29 in addition.Shown in arrow among Fig. 7 and Fig. 9, second stop element 27 is not to swing as among first embodiment, but move both vertically.

Original position has been shown among Fig. 7, and first stop element 4 of stop device 3 contacts with second stop element 27 on this position, and provides a backstop of shrinking gradually to gummed lath 16.Shown in Fig. 9 is the second place (channel position) of backstop 3, and second stop element 27 descends downwards in vertical direction on this position, makes to form a passage between first stop element 4 and second stop element 27.Gummed lath 16 is imported on the driving-belt 10 by means of the extruding of first stop element 4, and transmits to the transmitting
