Fig. 11 to 22 are schematic views of a process of grabbing a plate by a swing frame of a loading and unloading device of a machining center, wherein the plate represented by a dotted line is a plate to be machined, and the plate represented by a solid line is a machined plate.
When the extension 121 moves between the first rack 165 and the fourth rack 168, one of the first unidirectional gear 161 and the fourth unidirectional gear 164 is idle, and the other is engaged with the rack to turn the swing frame 10. Specifically, when the swing frame 10 is driven to move upward by the lifting power mechanism 26, the first one-way gear 161 is engaged with the first rack gear 165 to turn the swing frame 10 clockwise by approximately 90 °, and at this time, the fourth one-way gear 164 idles on the fourth rack gear 168. When the elevating power mechanism 26 drives the swing frame 10 to move downward, the fourth one-way gear 164 is engaged with the fourth rack 168 to transmit power, and the first one-way gear 161 is idled on the first rack 165, at this time, the swing frame 10 is turned clockwise by approximately 90 °.
When the lifting power mechanism 26 drives the swing frame 10 to move to the gap between the first rack 165 and the third rack 167, the second rack 166 and the fourth rack 168, the swing frame 10 does not rotate, at which time the brake mechanism 28 fixes the extension shaft 121, and the horizontal power mechanism 24 drives the swing frame 10 to horizontally move above the processing table 40.
When the extension 121 moves between the third rack 167 and the second rack 166, one of the third unidirectional gear 163 and the second unidirectional gear 162 is idle, and the other is engaged with the rack to turn the swing frame 10. Specifically, when the elevation power mechanism 26 drives the swing frame 10 to move upward, the second unidirectional gear 162 is engaged with the second rack gear 166 to transmit power to turn the swing frame 10 counterclockwise by approximately 90 °, and at this time, the third unidirectional gear 163 idles on the third rack gear 167. When the swing frame 10 is driven to move downward by the lifting power mechanism 26, the third one-way gear 163 is engaged with the third rack 167 to transmit power, and the second one-way gear 162 is idly rotated on the second rack 166, at this time, the swing frame 10 is turned counterclockwise by approximately 90 °.
The invention also discloses a plate feeding and discharging method, which adopts the plate feeding and discharging device to arrange the plate to be processed and the processed plate in the same trough and are arranged in a way of being nearly vertical; when the suction tool of the swing frame sucks the plate to be processed, the plate rises to a set height, and when the processing position is moved, the swing frame rotates forward by about 90 degrees, the plate is in a horizontal direction, and the plate to be processed is positioned above the swing frame; after the processed plate is sucked, the swing frame is lifted and reversely rotated for about 180 degrees and then is lowered to a processing position, and the plate to be processed is released to the processing position; the swinging frame horizontally moves to the processed plate material area of the trough, and synchronously rotates forward for about 90 degrees to release the processed plate into the trough. The concrete explanation is as follows:
As shown in fig. 11 to 12, after the swing frame 10 sucks the plate material in the trough 21, the lifting power mechanism 26 drives the swing frame 10 to rise to a predetermined position above the trough 21, at which time the first one-way gear 161 is engaged with the first rack 165 to rotate the swing frame 10 clockwise through a certain angle (75 to 85 degrees from the vertical) so that the plate material is inclined by 75 to 85 degrees, at which time the plate material is positioned slightly higher than the processing table 40 in height. The horizontal power mechanism 24 drives the horizontal slide table 22 to move toward the processing table 40.
As shown in fig. 13 to 15, after the swing frame 10 moves the sheet above the processing table 40, the sheet is in a horizontal state, where the extension shaft 121 is lowered by a small distance between the first rack 165 and the fourth rack 168 by the lifting power mechanism 26, the fourth rack 168 is engaged with the fourth one-way gear 164, the swing frame 10 is rotated clockwise by a small distance to rotate the sheet by 5 to 15 ° close to the horizontal state, and the first one-way gear 161 and the first rack 165 are idle at this time. Then, the lifting power mechanism 26 drives the swing frame 10 to continue to descend for a small distance, the suction nozzle at the other side of the swing frame 10, which is not used for sucking the plate, sucks the processed plate on the processing table 40, and the plate rises to a certain height (the plate is in an approximately horizontal state), at this time, the extending shaft 121 does not do any movement in the gap between the two racks. The horizontal power mechanism 24 drives the horizontal sliding table 22 to move away from the processing table 40 so that the swing frame 10 does not touch the processing table 40 when being turned over.
As shown in fig. 16 to 19, the swing frame 10 is further raised to a certain height by the elevating power mechanism 26 so that the extension shaft is located between the third rack 167 and the second rack 166, and the second unidirectional gear 162 is engaged with the second rack 166 to transmit power so that the swing frame 10 is turned counterclockwise by about 90 ° (the plate is in the vertical state), at which time the third unidirectional gear 163 idles on the third rack 167. After the extension shaft 121 rises to the highest point, it descends under the action of the lifting power mechanism 26, the third unidirectional gear 163 is meshed with the third rack 167 to transmit power, the second unidirectional gear 162 idles on the second rack 166, the swing frame 10 continues to turn counterclockwise by about 90 °, the swing frame 10 is in a horizontal state, and at this time, the extension shaft 121 is in a gap between racks.
As shown in fig. 20 to 22, the horizontal power mechanism 24 drives the horizontal sliding table 22 to move toward the processing table 40, the lifting power mechanism 26 drives the swing frame 10 to descend, and when the plate to be processed approaches the processing table 40, the suction nozzle breaks the vacuum, so that the plate falls on the processing table 40. After the plate is placed on the processing table 40, the swing frame 10 slightly rises a distance, and then the horizontal power mechanism 24 drives the horizontal sliding table 22 to move away from the processing table 40. When the swinging frame 10 is above the trough 21, the lifting power mechanism 26 drives the swinging frame 10 to descend, the extension shaft 121 moves between the first rack 165 and the fourth rack 168, the fourth one-way gear 164 is meshed with the fourth rack 168 to transmit power, the first one-way gear 161 idles on the first rack 165, at this time, the swinging frame 10 turns clockwise by about 90 degrees, the processed plate is in a vertical state, then the swinging frame 10 is continuously descended, the suction nozzle breaks vacuum, and the plate is placed at one end of the trough to finish feeding and discharging of one plate.
In other embodiments of the swing type plate loading and unloading device and the machining center of the present invention, the installation seat may be provided with a rotating rod and a rotating block mounted on the rotating rod, and both front and rear sides of the rotating block are provided with a picking and placing part for picking and placing plates (such as the rotating rod and rotating block structure as in the patent document No. cn2015196790. X). On the basis of the patent document of the No. CN201512996790. X, a rotating mechanism (namely a motor) is omitted, and four unidirectional transmission gear rack sets are used instead, so that the rotating rod is driven to reciprocally turn by the lifting of the mounting seat. The specific contents are as follows:
