The end of a plurality of glass tube 20 is inserted, to supply with in the rail groove 111a that is placed on place, higher position and the glass tube material end supports 111 on first whirligig 210 side farthest.The end of the glass tube 20 of supply alignment stand 110 is supported by the downside of rail groove 111a, and central authorities are supported by glass tube material center support 112, make glass tube 20 roll to first whirligig 210 along the inclined-plane, glass tube 20 in extreme lower position stops by the provisioning component 120 that is installed between the alignment stand 110 and first whirligig 210, so that pile up nattily and evenly distributed glass tube 20 otherwise.Next supplies with first whirligig 210 by provisioning component 120 1 to be arranged in a plurality of glass tube 20 in the alignment stand 110.
Provisioning component 120 is used for the glass tube 20 that next supply is arranged in alignment stand 110 between the adjacent disc 211a and 212a of first whirligig 210.Each of provisioning component 120 all comprises guider 121, two arresting levers 122 and 123, link rod 124 and arresting lever drivers 125.
Guider 121 supports arresting lever 122 and 123, so that these two arresting levers 122 and 123 can move up and down repeatedly.Guider 121 is arranged in below the nearest axle of alignment stand 110 (this is corresponding to the axle 212 of accompanying drawing), and is fixed to the predetermined base (not shown).Arresting lever 122 and 123 two guide holes that the insert axle around guider 121 tops parallel to each other (axle 212 among the figure) is symmetrically formed.
These two arresting levers 122 and 123 are inserted in the guide hole, so that can carry out moving up and down repeatedly.The raised zones of each is higher than axle 212 extensions of first whirligig 210 in the arresting lever 122 and 123 that protrudes above guider 121, and axle 212 is between arresting lever 122 and 123 simultaneously.In other words, the axle 212 of first whirligig 210 is between the arresting lever above the guider 121 122 and 123.And arresting lever extension 122a and 123a are respectively installed on the arresting lever 122 and 123 that extends as mentioned above.Arresting lever extension 122a and 123a extend to and are higher than arresting lever 122 and 123 above being positioned at the axle of guider 121 toward each other.Arresting lever extension 122a and 123a extend to till the glass tube 20 of the upper/lower positions on the inclined-plane of alignment stand 110 is met arresting lever extension 122a and 123a always.And the upper end of arresting lever extension 122a and 123a forms a little, so that take out glass tube 20.Each guide hole one side all is an opening, so that the central authorities of arresting lever 122 and 123 are exposed to a side.Arresting lever 122 and 123 central authorities that expose are by link rod 124 interconnection, so that these two arresting levers 122 and 123 move in the opposite direction.In other words, the end of link rod 124 is pivotally connected to the central authorities of these two arresting levers 122 and 123, and the central authorities of link rod 124 are pivotally mounted to the link rod rotating shaft 124a that installs and are installed to guider 121 1 sides between guide hole.Therefore, (or downwards) moves if one of them of these two arresting levers 122 and 123 makes progress, and the link rod 124 that then hingedly is connected to arresting lever 122 and 123 rotates around link rod rotating shaft 124a, and another arresting lever 123 (or 122) downward (or making progress) moves.In other words, by the connection to link rod 124, these two arresting levers 122 and 123 simultaneously but move in the opposite direction always.Arresting lever driver 125 drives arresting lever 122 and 123 repeatedly on direction up and down, and is connected to one of them bottom of arresting lever 122 and 123.Because by driving repeatedly fast of these two arresting levers 122 and 123, provisioning component 120 1 next supply glass tube 20 to first whirligigs are so pneumatic cylinder is suitable as arresting lever driver 125.Arresting lever driver 125 is worked by receiving from the signal of transducer 160 transmission.
Since provisioning component 120 the axle 211 and 212 of first whirligig 210 axially on be installed to both sides between first whirligig 210 and the alignment stand 110, so the two ends of arresting lever 122 and 123 support glass tube materials 20.
Gou Zao provisioning component 120 is according to work as described below as mentioned above.
If glass tube 20a is supplied with first whirligig 210, continuous feed cutter sweep 200 cuts then, but still do not separate with alignment stand 120, the glass tube 20 that then is arranged on the alignment stand 110 remains on the appropriate location by upwards being provided with of arresting lever 123 of placing farthest.Therefore, the glass tube 20 that is arranged on the alignment stand 110 is stopped by arresting lever 123, so that they are not supplied with first whirligig 210.If the glass tube 20a that supplies with first whirligig 210 and be fed into cutter sweep 200 becomes separate fully with alignment stand 110, then transducer 160 detects that this is true and transmit corresponding signal and give arresting lever driver 125.The arresting lever driver 125 of receiving this signal drives arresting lever 123 downwards, and another arresting lever 122 simultaneously moves up.As a result, a plurality of glass tube 20 of running on the arresting lever 123 move down along the inclined-plane of alignment stand 110.Lower glass tube material is farthest crossed arresting lever 123 and is rolled down, between two adjacent disc 211a and 212a of first whirligig 210, to supply with it.Yet, immediately following on the arresting lever 122 that a glass tube of this lower glass tube material back farthest runs into to move up.Behind one of them supply whirligig 210 of glass tube 20, arresting lever driver 125 is carried out control, to return initial condition.In other words, arresting lever 123 moves up, and another arresting lever 122 moves down.Therefore, a plurality of glass tube 20 that before stopped by arresting lever 122 stop further to move by the arresting lever 123 that moves up now.
Feeder 140 is used for the glass tube 20a that will supply with on the adjacent disc 211a of first whirligig 210 and 212a predetermined length is fed into cutter sweep 200.Each feeder 140 all comprises feed unit, pressure unit and stop block.
Feed unit applies the glass tube 20a that power give to be supplied with first whirligig 210 vertically, and wherein glass tube 20a just rotates on the dish 211a of first whirligig 210 and 212a.Feed unit comprises feed rolls 141, feeding pedestal 142, roller rotating driver and base driver.
The bottom of the upper outer circumferential surface of feed rolls 141 contact glass tube 20a, and rotating, thus glass tube 20a axially on apply power, wherein glass tube 20a rotates on the dish 211a of first whirligig 210 and 212a.In other words, the direction of the linear velocity of the upper outer circumferential surface of feed rolls 141 is axial consistent with glass tube 20a's, and feed rolls 141 rotations, makes this direction become the direction that stop block is faced.By the friction that produces by the zone that contacts with glass tube 20a, glass tube 20a axially on apply power and give glass tube 20a.If during the glass tube 20a that supplies with on first whirligig 210 rotates by first whirligig 210, the predetermined length of glass tube 20a is fed into cutter sweep 200 and cuts, then glass tube 20a contacts feed rolls 141, and because the friction that feeding produces, first whirligig can smooth rotation.Therefore, feed rolls 141 must move up and down below glass tube 20a, so that it only contacts feeding glass tube 20a during feeding glass tube 20a, and is separating with glass tube 20a At All Other Times.This realizes by the base driver that describes below.The roller rotating driver rotates feed rolls 141, and comprises motor 143c.Motor 143c is fixed to feeding pedestal 142, and produces the revolving force that can rotate feed rolls 141.The revolving force that motor 143c produces is delivered to feed rolls 141 by predetermined shaft, chain 143a and the belt 143b that is connected these two axles.Feeding pedestal 142 is installed on the pedestal 148, makes it to move up and down by base driver.In other words, feeding pedestal 142 supports feed rolls 141 and motor 143c mounted thereto, moves up and down repeatedly with these parts.Base driver is carried out and is moved up and down the operation of feeding pedestal 142, and comprises cylinder (cylinder) 144, guide rod 145 and guider 146.The middle body of guider 146 is formed with the access opening that inserts and guide rod 145 is installed.Above being fixed to, the upper end of guider 146 is installed into lower surface to the pedestal 148 of pedestal 142.The hole that is communicated with the access opening of guider 146 forms in pedestal 148 (guider 146 is fixed to the upper).Guide rod 145 is inserted in the access opening of guider 146, makes the upper end to protrude above pedestal 148, thereby can move up and down.The upper end of the guide rod 145 that protrudes above pedestal 148 is fixedly connected to the lower surface of feeding pedestal 142.Therefore, if guide rod 145 moves up and down, then feeding pedestal 142, the motor 143c and the feed rolls 141 that are connected to into a pedestal 142 also move up and down.Cylinder 144 is connected to the bottom of guide rod 145, moving up and down guide rod 145, and is installed on the pre-determined constant part.Referring to accompanying drawing, cylinder 144 is fixed on the side upwardly extending cylinder fixed support 146a below guider 146, and the bottom of the columnar shaft of cylinder 144 is connected to the bottom of guide rod 145 via columnar shaft fixed support 144a.
Pressure unit applies downward pressure and give the glass tube 20a that moves by feed unit on it is axial, so that glass tube 20a closely touches feed rolls 141, also comprises repeatedly the structure of mobile feeder pressure roller 151.
Feeder pressure roller 151 is pivotally mounted on first tumbler 210, so that the upper area of the glass tube 20a that contact is being fed by touching feed rolls 141.As shown in FIG., feeder pressure roller cursor pillar 153 is installed on the pedestal 148, extends so that make the one side be higher than whirligig 210.Feeder pressure roller turning arm 152 hingedly is connected to the upper area of feeder pressure roller cursor pillar 153, makes feeder pressure roller turning arm 152 to rotate around the rotating shaft consistent with the major axis of glass tube 20a.Feeder pressure roller 151 is installed in rotation on an end of the side of feed rolls 141 upwardly extending feeder pressure roller turning arm 152.And the columnar shaft of cylinder 154 is connected to the other end of the feeder pressure roller turning arm 152 relative with the end that feeder pressure roller 151 is installed.Cylinder 154 is fixed to upper area from feeder pressure roller cursor pillar 153 at the upwardly extending extension bracket 153a towards the side of cylinder 154.Therefore, if cylinder 154 work, then feeder pressure roller turning arm 152 carries out the back rotation of coming repeatedly, so feeder pressure roller 151 also moves up and down repeatedly.Feeder pressure roller 151 moves up and down repeatedly, so that it does not hinder the new glass tube material 20 of supplying with first whirligig 210, and make feeder pressure roller 151 away from glass tube 20a, when not having feeding glass tube 20a, realize smooth rotation by first whirligig 210.
Glass tube 20a must be by feeder 140 feeding predetermined length amounts.Therefore, each feeder 140 can further comprise stop block, and described stop block is installed on the forward facing position in the path that the glass tube 20a about feeding advances.Stop block comprises retainer 156, the end in contact of described retainer 156 and the glass tube 20a that moves by feeder 140, thereby the feeding length of restriction glass tube 20a.Retainer 156 is by stop driver 156a axially moving forward and backward along glass tube 20a.Retainer 156 moves forward and backward, make that supplying with enlarging at be cut into two sections glass tube 20a by cutter sweep 200 one section (corresponding to the glass tube 21 with predetermined length) forms device 300, the one end is run on the end of retainer 156 owing to retainer 156 moves backward.In other words, as glass tube 20a during by feeder 140 feedings, retainer 156 moves forward, when the glass tube 21 with predetermined length when cutter sweep 200 takes out and supplies with enlarging and forms device 300, retainer 156 moves backward.
Point according to the cutting knife 230 that cutter sweep 200 is installed is installed to two feeders 140 and the relative side of a side that retainer 156 is set.One of them feeder 140 is installed near cutter sweep 200, and 20a shortens gradually along with glass tube, and glass tube 20a finally is fed into cutter sweep 200.
