[0032] Example

[0033] Please refer to Figure 1-5 The cardboard loading machine provided in this embodiment includes a frame 1, a lifting silo and a loading robot. The lifting silo includes a silo plate 21, a first drive motor 22 and two sets of lifting mechanisms. The first drive motor 22 is installed on the top of the frame 1. The first drive motor 22 is connected to a drive shaft, and two first driving wheels 23 are installed on the drive shaft; the two sets of lifting mechanisms are respectively arranged on both sides of the silo plate 21, and the first drive motor 22 is used to realize the synchronous lifting of the two sets of lifting mechanisms. Specifically, the lifting mechanism includes a first driven wheel 24, a driving wheel shaft 25, a second driving wheel 26 and a second driven wheel 27. The driving wheel shaft 25 is fixed on the top of the frame 1, and the driving wheel shaft 25 adopts a segmented splicing structure, that is, the driving wheel shaft 25 includes a main wheel The main wheel shaft 251 and two secondary wheel shafts 252 are respectively connected to the two ends of the main wheel shaft 251 through couplings. Since the size of the warehouse plate 21 is relatively large, if the driving wheel shaft 25 adopts a whole shaft made of a blank, the whole shaft is relatively long, which causes the whole shaft to bend during the processing due to the combined force of radial cutting force and radial separation of the clamping, resulting in an increase in the processing cost of the driving wheel shaft 25. This embodiment adopts a three-section driving wheel shaft 25, and the lengths of the main wheel shaft 251 and the secondary wheel shaft 252 are both relatively short, which can easily control the bending deformation of the main wheel shaft 251 and the secondary wheel shaft 252, thereby achieving the purpose of reducing the processing cost.

[0034] In this embodiment, the driving wheel shaft 25 of each lifting mechanism is equipped with a first driven wheel 24, and the first driven wheel 24 and the first driving wheel 23 are driven by a chain 29. When the driving motor rotates, the driving motor realizes synchronous driving of the two lifting mechanisms through the chain 29.

[0035] In this embodiment, each lifting mechanism is provided with two second driving wheels 26, that is, a second driving wheel 26 is respectively installed on the two secondary wheel shafts 252 of a driving wheel shaft 25, and correspondingly, two second driven wheels 27 are provided at the bottom of the frame 1, and a lifting chain 29 is wound between a second driving wheel 26 and a second driven wheel 27, and the warehouse plate 21 is fixed to the lifting chain 29. When the driving motor drives the driving wheel shaft 25 to rotate through the chain 29, the rotation of the driving wheel shaft 25 is converted into the rotation of the chain 29 through the second driving wheel 26 and the second driven wheel 27. Since the warehouse plate 21 is fixed to the chain 29, the rotation of the chain 29 is converted into the lifting movement of the warehouse plate 21.

[0036] In the actual production process, the frame 1 is also provided with a laser sensor or a photoelectric sensor for detecting the amount of remaining cardboard on the storage board 21, and the controller controls the rotation of the drive motor through the detection data of the sensor, so that the storage board 21 rises as needed, ensuring that the top layer of cardboard in the cardboard stack on the storage board 21 can be obtained by the loading robot.

[0037] The feeding robot is used to obtain the cardboard on the storage plate 21 and transfer the cardboard to the external conveyor belt. The feeding robot includes a base 41, a connecting plate 42, a lifting type vacuum suction nozzle 45 fixing frame and a feeding drive mechanism. The base 41 is a T-shaped structure. The wing plate 412 of the base 41 is fixed on the frame 1. The web 411 of the base 41 is arranged horizontally. A second driving motor 46 is installed on the web 411 of the base 41. At the same time, an active synchronous wheel 47 and a driven synchronous wheel are installed on the web 411. A driving synchronous wheel 47 and a driven synchronous wheel are arranged between the active synchronous wheel 47 and the driven synchronous wheel. There is a synchronous belt, and the second drive motor 46 drives the active synchronous wheel 47 to rotate. The synchronous belt is connected to the connecting plate 42, and the upper end of the connecting plate 42 is connected to the wing plate 412 of the base 41 through a slide rail. The connecting plate 42 is connected to a liftable vacuum suction nozzle 45 fixing frame, and the liftable vacuum suction nozzle 45 fixing frame includes a lifting cylinder 43 and a fixing frame 44 on which a plurality of vacuum suction nozzles 45 are installed. The lifting cylinder 43 is installed at the lower end of the connecting plate 42, and the piston rod of the lifting cylinder 43 is connected to the fixing frame 44. The lifting cylinder 43 drives the fixing frame 44 to rise and fall. When loading cardboard, the loading robot moves to the top of the cardboard pile, the lifting cylinder 43 extends downward, the vacuum suction nozzle 45 contacts and sucks the cardboard, then the lifting cylinder 43 retracts upward, the vacuum suction nozzle 45 sucks a cardboard and moves upward, thereafter the loading robot moves to the top of the conveyor belt outside the loading machine, the lifting cylinder 43 extends downward, the vacuum suction nozzle 45 breaks the negative pressure, the cardboard is separated from the vacuum suction nozzle 45, the cardboard is placed on the conveyor belt, then the lifting cylinder 43 retracts and resets, the loading robot resets and moves into the loading machine, ready for the next cardboard loading.

[0038] It should be noted that the fixing frame 44 and the connecting plate 42 may be connected via a slide rail, and the slide rail is used to ensure the straightness of the lifting and lowering of the fixing frame 44 and avoid abnormal shortening of the service life of the lifting cylinder 43.

[0039] In this embodiment, the cardboard loading machine also includes a limiting device located above the storage plate 21, the limiting device includes a limiting plate 51 and a connecting rod 52, one end of the connecting rod 52 is fixed to the frame 1, and the other end of the connecting rod 52 is fixed to the limiting plate 51, and the limiting plate 51 is provided with a guiding inclined surface 53. When placing cardboard on the storage plate 21, several cardboards on the upper layer of the cardboard stack are in contact with the vertical plane of the limiting plate 51, which plays a role in positioning the cardboard stack, preventing the cardboard from deviating too far from the loading robot, and preventing the loading robot from being unable to normally absorb the cardboard. In addition, in this embodiment, a guiding inclined surface 53 is provided on the limiting plate 51. Even if the position of the lower part of the cardboard stack deviates a little, as long as it is within the error range, the guiding inclined surface 53 can move the cardboard to the preset position during the rising of the storage plate 21, ensuring that the loading robot can normally absorb the cardboard.

[0040] In this embodiment, casters are also provided at the bottom of the frame 1 to facilitate the movement of the loader.

[0041] It should be noted that the cardboard feeder is also equipped with a controller, such as a PLC, to control the start and stop of the first drive motor 22, the second drive motor 46 and the lifting cylinder 43, as well as the on and off of the negative pressure.

[0042] The utility model realizes automatic loading of paperboards by adopting a paperboard loading machine, realizes synchronous driving of two lifting mechanisms by a driving motor, and realizes lifting and lowering of the storage plate 21 by utilizing the two lifting mechanisms.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
