Description
CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Taiwanese Patent Application No. 107145999, filed on Dec. 19, 2018, and Taiwanese Patent Application No. 108136662, filed on Oct. 9, 2019.


FIELD

The disclosure relates to a loading and unloading system, more particularly to an automatic loading and unloading device.


BACKGROUND

A loading and unloading device of a conventional stitching machine includes a work platform, a loading unit and an unloading unit. The work platform defines a loading area, a processing area, and a receiving area. A stitching machine is provided on the processing area. During processing, an operator can put a plate loaded with two shoe components on the loading area, and the plate is delivered to the processing area for processing the shoe components loaded thereon through the loading unit. Finally, the plate with the processed shoe components is delivered to the receiving area through the unloading unit for the operator to collect the product at the receiving area.


Since the loading area of the loading and unloading device of the conventional stitching machine is away from and is not adjacent to the receiving area, the operator must continually move between the loading area and the receiving area. If two operators must be provided, the labor cost is increased. If an additional receiving device is provided, an additional drive mechanism is required, thereby increasing the cost of the drive mechanism.


SUMMARY

Therefore, an object of the present disclosure is to provide an automatic loading and unloading device that is capable of alleviating at least one of the drawbacks of the prior art.


According to this disclosure, an automatic loading and unloading device is suitable for automatically moving at least one plate. The automatic loading and unloading device includes a frame, an unloading unit, a receiving unit and a receiving link unit. The frame defines a processing area that is suitable for receiving the at least one plate along a transferring direction, an unloading area disposed on one side of the processing area, and a receiving area disposed on one side of the unloading area that is away from the processing area. The unloading unit is disposed on the frame, and includes an unloading slide rail extending along an unloading direction perpendicular to the transferring direction, and an unloading drive group movably disposed on the unloading slide rail for driving the at least one plate to move from the processing area to the unloading area along the unloading direction. The receiving unit is disposed on the frame, and includes a receiving slide rail extending along the transferring direction, and a receiving lift group movably disposed on the receiving slide rail for driving the at least one plate to move from the unloading area to the receiving area along the transferring direction. The receiving link unit interconnects the unloading drive group and the receiving lift group such that when the unloading drive group moves along the unloading slide rail, the unloading drive group can synchronously drive the receiving lift group to move along the transferring direction.

The receiving link member 91 is a rope wound around the pulleys 92, and interconnects the unloading drive member 721 and the sliding member 822 of the receiving lift group 82.


The loading, unloading and receiving operations of a plurality of the plates 3 using the automatic loading and unloading device of this disclosure will be sequentially described below. Each plate 3 may be loaded with two shoe components, for example, an upper 11 and a decorative piece 12, as shown in FIG. 1.


1. Loading operation: Referring to FIGS. 1, 2 and 3 to 7, when an operator or a machine arm places one of the plates 3 loaded with the shoe components 11 and 12 on the preparation area 401 of the platform 42, the loading link member 61 is activated to pull the loading lift group 52 from a loading position, as shown in FIG. 3, in which the loading lift group 52 is located in the preparation area 401 away from the loading area 402, to a preparing position, as shown in FIG. 4, in which the loading lift group 52 is adjacent to the loading area 402. At this time, the loading push rods 525 extend out of the loading channels 424, and push the one of the plates 3 to move from the preparation area 401 to the loading area 402 along the transferring direction (X).


During movement of the loading lift group 52 from the loading position (see FIG. 3) to the preparing position (see FIG. 4), the rollers 524 roll on the upper rail surfaces 501 of the lift tracks 50, and move from the upper ends 504 to the lower ends 505 of the inclined surfaces 503 when in contact with the inclined surfaces 503 that are proximate to the loading area 402, thereby overcoming the blocking forces of the limiting members 526, so that the lifting plate 523 can descend toward the lower rail surface 502 until the rollers 524 are located between the upper and lower rail surfaces 501, 502 of the lift tracks 50. At the same time, each loading push rod 525 is driven to descend from a loading exposed position (the loading push rods 525 being shown in imaginary lines in FIGS. 5 and 6) to a loading hidden position (the loading push rods 525 shown in solid lines in FIGS. 5 and 6), so that each loading push rod 525 is located below a horizontal surface of the one of the plates 3. Since a height of each loading push rod 525 in the loading hidden position is lower than its height in the loading exposed position, the loading push rods 525 can move along with the loading lift group 52 back to the loading position, as shown in FIG. 3, without interfering with the plate 3.


It is worth to mention herein that, during movement of the loading lift group 52 from the preparing position to the loading position, the rollers 524 located below the upper rail surfaces 501 of the lift tracks 50 will move until they contact the inclined surfaces 503 which are adjacent to the preparation area 401, and move from the lower ends 505 to the upper ends 504 of the inclined surfaces 503, so that the lifting plate 523 ascends in a direction away from the sliding member 522 until the limiting members 526 contact the ring grooves 5251 of the loading push rods 525 and generate blocking forces that prevent the loading push rods 525 from moving further upward. At this time, the rollers 524 contact the upper rail surfaces 501 of the lift tracks 50, and drive each loading push rod 525 to ascend from the loading hidden position to the loading exposed position through the lifting plate 523.


2. Preparation Operation:


Referring to FIGS. 1 to 4 and 7, when the preparation drive member 54 is in a feeding position, as shown in FIG. 4, in which the preparation drive member 54 is proximate to the loading area 402, the preparation drive cylinder 551 will push the conveying push rod 552 to move from a conveying hidden position (the conveying push rod 552 being shown in imaginary line in FIG. 7), in which the conveying push rod 552 is hidden beneath the platform 42, to a conveying exposed position (the conveying push rod 552 being shown in solid line in FIG. 7), in which the conveying push rod 552 extends out of the conveying channel 423 of the platform 42. Through this, when the preparation drive member 54 is moved along the preparation slide rail 53 from the feeding position (see FIG. 4) to an unloading position (see FIG. 3), in which the preparation drive member 54 is proximate to the processing area 403, the conveying push rod 552 that extends out of the conveying channel 423 can push the one of the plates 3 located at the loading area 402 to enter the processing area 403 along the transferring direction (X). At the same time, the loading push rods 525 extending out of the loading channels 424 can synchronously push the next plate 3 from the preparation area 401 to the loading area 402 along the transferring direction (X). By repeating the aforesaid steps, only one preparation drive member 54 is used to push each plate 3 from the preparation area 401 to the loading area 402, and to synchronously push the plate 3 located originally at the loading area 402 to enter the processing area 403 for processing.


3. Unloading Operation:


Referring to FIGS. 1, 2 and 8, after the processing of the shoe components 11 and 12 loaded on the one of the plates 3 by the stitching machine 2 is completed, the unloading drive member 721 is moved along the unloading slide rail 71 from a processing position (the unloading pushing member 722 being shown in solid line in FIG. 8), in which the unloading drive member 721 is away from the unloading area 404, to a processing completion position (the unloading pushing member 722 being shown in imaginary line in FIG. 8), in which the unloading drive member 721 is proximate to the unloading area 404, and drives the unloading pushing member 722 to push and move the one of the plates 3 loaded with the processed shoe components 11 and 12 from the processing area 403 to the unloading area 404.


4. Receiving Operation:


Referring to FIGS. 1, 2, and 8 to 12, when the unloading drive member 721 is moved from the processing completion position back to the processing position along the unloading slide rail 71, the receiving link member 91 will pull the receiving lift group 82 to move from an unloading position (the receiving lift group 82 being shown in solid lines in FIGS. 9 and 10), in which the receiving lift group 82 is located at the unloading area 404 and is proximate to the processing area 403, to a receiving position (the receiving lift group 82 being located at the rightmost side of FIG. 10), in which the receiving lift group 82 is located at the receiving area 405 and is adjacent to the preparation area 401. At this time, the receiving push rods 825 are located at a receiving exposed position (the receiving push rods 825 being shown in solid lines in FIGS. 10 and 11) that extend out of the receiving channels 422 of the platform 42, and push the one of the plates 3 loaded with the processed shoe components 11 and 12 to move from the unloading area 404 to the receiving area 405 along the transferring direction (X).


During movement of the receiving lift group 82 from the unloading position to the receiving position, as shown in FIG. 10, the rollers 824 rolling on the upper rail surfaces 801 of the lift tracks 80 will contact the inclined surfaces 803 of the lift tracks 80 which are proximate to the receiving area 405, and sequentially move from the upper ends 804 to the lower ends 805 of the inclined surfaces 803, thereby overcoming the blocking forces of the limiting members 826, so that the lifting plate 823 descends toward the sliding member 822, until the rollers 824 contact the lower rail surfaces 802 of the lift tracks 80, and drive each receiving push rod 825 to descend from the receiving exposed position to a receiving hidden position (the receiving push rods 825 being shown in imaginary lines in FIGS. 10 and 11) located beneath the horizontal surface of the plate 3. Through this, the height of each receiving push rod 825 at the receiving exposed position is higher than its height at the receiving hidden position along the lifting direction (Z).


During movement of the unloading drive member 721 from the processing completion position back to the processing position along the unloading slide rail 71, the receiving lift group 82 is pulled by the receiving link member 91 to move from the receiving position to the unloading position. At this time, since each receiving push rod 825 is located at the receiving hidden position and does not extend out of the platform 42, each receiving push rod 825 can move along with the receiving lift group 82 back to the unloading position without interfering with the plate 3.


During movement of the receiving lift group 82 from the receiving position to the unloading position, the rollers 824 located on the upper rail surfaces 801 of the lift tracks 80 will move until they contact the inclined surfaces 803 of the lift tracks 80 which are proximate to the unloading area 404, and then sequentially move from the lower ends 805 to the upper ends 804 of the inclined surfaces 803, so that the lifting plate 823 ascends in a direction away from the sliding member 822, until the limiting members 826 contact the ring grooves 8251 of the receiving push rods 825 to generate blocking forces. Further, the rollers 824 contact the upper rail surfaces 801, and drive each receiving push rod 825 to ascend from the receiving hidden position to the receiving exposed position through the lifting plate 823. By repeating the aforesaid steps, only one unloading drive group 72 is used to push each plate 3 loaded with the processed shoe components 11 and 12 to move from the unloading area 404 to the receiving area 405, and tp synchronously push the plate 3 located originally at the processing area 403 to enter the unloading area 404.


Through this, the operator or the machine arm that faces the preparation area 401 and the receiving area 405 does not need to change his/its position, and can place the plate 3 loaded with shoe components 11 and 12 to be processed on one side and receive the plate 3 loaded with shoe components 11 and 12 that have been processed on another side.


It is worth to mention herein that the loading link unit 6 and the receiving link unit 9 composed of the aforementioned ropes and pulleys may also achieve the purpose of linkage through a brake line group.


Referring to FIG. 13, the second embodiment of the automatic loading and unloading device of this disclosure is shown to be identical to the first embodiment. However, in this embodiment, the frame 4 further includes a plurality of roller shafts 43 and a plurality of gears 44. The roller shafts 43 are journalled on the frame body 41, and are arranged from the unloading area 404 to the receiving area 405 along the transferring direction (X). Each gear 44 is connected to one side of a corresponding one of the roller shafts 43 located at the unloading area 404. Each gear 44 rotates coaxially with the corresponding roller 43.


The receiving unit 8 further includes a sliding member 83 connected to the receiving link member 91 (see FIG. 2). The sliding member 83 has a meshing portion 831 meshing with a corresponding one of the gears 44. Due to linkage with the receiving link member 91, the sliding member 83 can move reciprocally within the unloading area 404, so that the meshing portion 831 of the sliding member 82 can sequentially drive the gears 44 to rotate, and sequentially drive the roller shafts 43 to rotate, thereby facilitating movement of the plate 3 loaded with the processed shoe components 11 and 12 to the receiving area 405 through the roller shafts 43.


It should be noted herein that the automatic loading and unloading device of this disclosure is not limited to installing the stitching machine 2. In other variations of this embodiment, processing equipment, such as spot welding machine, roughing machine, etc, may also be installed. The purpose of loading, automatic preparation, automatic unloading and automatic receiving may be similarly achieved.


While the disclosure has been described in connection with what are considered the exemplary embodiments, it is understood that this disclosure is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
