As shown in figure 1, the device for stacking and counting gloves in the utility model realizes the stacking of gloves through the working platform 1 placed on the horizontal plane. The bottom of the working platform 1 is provided with a supporting leg 18 for supporting the working platform 1, and the supporting leg 18 and the working platform 1 can be relatively folded and fixed, or adopt the structural form of a telescopic supporting leg, and the folding and telescopic functions are superposed.
The utility model discloses in, in order to realize stacking of gloves in 1 different positions department of work platform, can be provided with lateral shifting base 2 in one side that work platform 1 kept away from the export of glove knitting machine, lateral shifting base 2's effect lies in fixed lateral driving structure 3 and makes to move actuating mechanism 3 and can drive lateral shifting slider 5 steadily and move on lateral shifting base 2. In the above working process, different transverse driving mechanisms 3 can be selected according to actual situations, for example, when the transverse driving mechanism 3 is set to be a transmission lead screw structure driven by a transverse driving motor, a transmission form of a lead screw nut pair is adopted between the transverse driving mechanism 3 and the transverse moving slider 5, and in order to ensure the stability of the transverse moving slider 5 in transverse movement, the transverse moving slider 5 generally needs to be set to be a structure form sliding along the guide polished rod or sliding along the transverse moving slide rail 6. The guide polished rod or the transverse moving slide rail 6 is fixed on the transverse moving base 2. When the transverse driving mechanism 3 is configured as a rack-and-pinion driving mechanism, the rack structure needs to be fixed on the transverse moving base 2, and the gear structure and a transverse driving motor for driving the gear to move are disposed on the transverse moving slide block 5.
The utility model discloses in, in order to realize accepting and stacking of gloves, need the fixed longitudinal movement base 6 that is provided with and sets up with work platform 1 is perpendicular on lateral shifting slider 5, install the longitudinal movement drive mechanism 11 of drive longitudinal movement slider 10 at vertical motion on the longitudinal movement base 6, and different drive structures can be selected as required to longitudinal movement drive mechanism 11. The driving structure of the longitudinal driving mechanism 11 is preferably selected by referring to the arrangement mode of the transverse driving mechanism 3 under the premise of considering stability. When a transmission lead screw structure is adopted, a longitudinal driving motor 12 on the longitudinal moving base 6 is required to drive a longitudinal driving mechanism 11 adopting the transmission lead screw, and a transmission form of a lead screw nut pair is used for driving the longitudinal moving slide block 10 to move vertically. Meanwhile, in order to ensure the operation stability of the longitudinally moving slide block 10, a guide polished rod or a longitudinally moving slide rail 7 can be arranged in an auxiliary manner. The guide polished rod and the longitudinal moving slide rail 7 are arranged on the longitudinal moving base 6.
The utility model discloses in, in order to realize accepting the gloves that the export of gloves braider landing, need set up pull support body 15 on longitudinal movement slider 10, be provided with on the pull support body 15 and accept tray 8 by pull drive unit 13, the gloves of pull drive gear 14 driven, gloves accept tray 8 have for work platform 1 with the same incline direction of gloves braider export to satisfy the landing of gloves.
The utility model discloses at the during operation, need be through the count sensor on the pull support body 15, for example photoelectric sensor, realize whether landing in gloves bearing tray 8 go on responding to and count to weaving the gloves that accomplish the landing. When the counting sensor senses that the gloves slide down to the glove bearing tray 8, the signal is transmitted to the control unit, the control unit controls the transverse driving motor to start working, and the transverse moving sliding block 5 moves towards one end of the working platform 1 through the transverse driving mechanism 3 and the transverse moving sliding rail 4. When the transverse driving motor moves to a set position and is sensed by the proximity sensor, the control unit receives a signal and controls the transverse driving motor to stop working. At this time, the control unit sends a control command, such as a pulse signal, to the longitudinal driving motor 12, so that the longitudinal driving motor 12 drives the longitudinal driving mechanism 11 to drive the longitudinal moving slider 10 to move downward to a distance close to the working platform 1, and then stops. At this time, the drawing driving unit 13 on the longitudinal moving slider 10 starts to work under the control of the control unit, so that the drawing driving gear 14 starts to rotate, the rotation of the drawing driving gear 14 starts to move the drawing driving rack 9 engaged with the drawing driving gear, and the drawing driving rack 9 drives the glove carrying tray 8 connected or integrated with the drawing driving gear to move towards one side relative to the drawing frame body 15. In the course of the relative movement of the glove carrying tray 8 and the drawer body 15, the glove on the glove carrying tray 8 is limited by the drawer body 15 and falls onto the work platform 1 below the drawer body 15. After gloves drop on work platform 1 below pull support body 15, pull drive unit 13 can drive pull drive gear 14 to rotate under the effect of the control unit for pull drive rack 9 drives gloves bearing tray 8 and resets. The reset glove bearing tray 8 and the drawing frame body 15 can continuously move downwards for a small distance under the action of the longitudinal driving motor 12 and the longitudinal driving mechanism 11 to drive the longitudinal moving slide block 10 so as to flatten the gloves dropped on the working platform 1. After the flattening is finished, the control unit controls the executing components in the transverse moving unit, the longitudinal moving unit and the drawing unit to reset, and the next glove operation process is executed. It should be noted that, because the number of gloves is gradually increased during the glove stacking process, and the height of the gloves relative to the horizontal workbench is gradually increased, the control unit controls the longitudinal driving motor 12 to make the distance that the longitudinal driving mechanism 11 drives the longitudinal moving slide block 10 to move downwards gradually decrease until the control unit obtains that the number of the stacked gloves exceeds the set number through the counting sensor, and then the next glove stack is performed.
The utility model discloses in, if what adopt is that the conveyer belt 16 that records in embodiment 2 is as work platform, then need not to set up the lateral shifting unit for work platform 1 motion, and only need rotate the displacement distance through conveyer belt drive unit 17 drive conveyer belt 16, can realize the demand that different positions department gloves become to pile up and stack. The transmission form of the mechanical structure in the automatic glove stacking counting can be further simplified.
Finally, although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description of the present description is for clarity reasons only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
