DETAILED DESCRIPTION

[0025] To make the purposes, methods, solutions, and advantages of the embodiments of the present invention more clear, the methods and solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the figures herein can be arranged and designed in various different configurations.

[0026] Example 1: Figure 1 As shown, a bag-picking mechanism includes a base 51 and a bag-picking claw 52 arranged on the side wall of the base 51, and also includes: a clamping component 53 for clamping the bag cloth, and the clamping component 53 and the bag-picking claw 52 are arranged on the same side wall of the base 51.

[0027] During the specific implementation process, the clamping assembly can be provided with a group of parallel clamping jaws, and the clamping jaw structure is the existing technology and will not be described in detail.

[0028] like Figure 1 and Figure 5 As shown, in this embodiment, the purse-picking claw 52 includes: an upper clamping member 521; a lower clamping member 522, wherein the upper clamping member 521 and the lower clamping member 522 are symmetrically arranged on the same side wall of the base 51; the lower clamping member 522 includes a plurality of fingers; a driving device, wherein the driving device is arranged in the inner cavity of the base 51; the upper clamping member 521 and the finger portions partially pass through the side wall of the base 51 and are connected to the driving device, and the distance between the upper clamping member 521 and the finger portions is adjusted by the driving device.

[0029] In the specific implementation process, the function of the bag-picking mechanism 5 is to clamp the packaged object. The upper clamping member 521 and the lower clamping member 522 can be clamped by two plates, or they can be clamped by two plates. Figure 5As shown, the lower clamping member 522 is configured as a claw with multiple fingers. Of course, both the upper clamping member 521 and the lower clamping member 522 can also be configured as claws. The driving device can be a bidirectional telescopic cylinder or hydraulic cylinder. A through hole is provided at the connection between the base 51 and the bag-picking claw 52 to allow the upper clamping member 521 and the lower clamping member 522 to move up and down. The upper and lower clamping members pass through the through hole and are connected to the output shaft of the telescopic cylinder.

[0030] like Figure 1 As shown, a bag-pulling and cloth-pulling device includes a vertical guide rail 2 arranged on a first frame 1, a vertical clamping mechanism 3 slidably connected to the vertical guide rail 2, and also includes: a bag-pulling mechanism 5; the clamping assembly corresponds to the placement surface of the packaged object.

[0031] During specific implementation, the clamping assembly needs to clamp the wrapping cloth and lay it on the placement surface of the packaged object. Therefore, the height of the clamping assembly and the placement surface of the packaged object should be as close as possible. After the vertical clamping mechanism 3 transports the laying wrapping cloth to the lower wrapping cloth laying surface, the bag-picking mechanism 5 performs the bag-picking operation. When the bag-picking mechanism 5 extends into the frame 1 to clamp the packaged object, the clamping assembly clamps the edge of the wrapping cloth. When the bag-picking mechanism 5 removes the packaged object, the clamping assembly pulls the wrapping cloth to unfold horizontally. After moving to the appropriate position, the clamping assembly releases the wrapping cloth, and the lower wrapping cloth is laid. The bag-picking mechanism 5 then moves the packaged object to the second frame 4 for side wrapping.

[0032] like Figure 2-4 As shown, in this embodiment, it includes: a placement table 11 for placing packaged objects, the placement table 11 is connected to the bottom wall of the frame 1; the upper surface of the placement table 11 is provided with a groove 111 for the finger to pass through.

[0033] In the specific implementation process, in order to facilitate the lower clamping member 522 in the bag-picking mechanism 5 to extend into the bottom of the packaged object while ensuring the stability of the packaged object, the placement table 11 is provided with a groove 111. If the lower clamping member 522 is set to a plate shape, the placement table 11 is as follows. Figure 3 As shown in the figure, the groove 111 is set. At this time, the stability of the packaging and the flatness of the lower packaging cloth are difficult to ensure. Therefore, the present invention sets the lower clamp 522 to a claw shape including multiple fingers. At this time, the groove 111 on the placement table 11 is as shown in the figure. Figure 4 The arrangement shown increases the contact area between the packaged object and the placement table 11, ensuring the placement stability of the packaged object while ensuring the flatness of the lower wrapping cloth.

[0034] like Figure 2 and Figure 6As shown, in this embodiment, the vertical clamping mechanism 3 includes: an upper clamping member 31; a lower clamping member 32; a connecting rod 33, and the upper clamping member 31 is connected to the lower clamping member 32 through the connecting rod 33; at least one component among the upper clamping member 31, the lower clamping member 32 and the connecting rod 33 is slidably connected to the vertical guide rail 2.

[0035] In the specific implementation process, the vertical clamping mechanism 3 can be as follows Figure 2 As shown in FIG, the whole is set in a square frame shape, and the upper and lower edges of the wrapping cloth are clamped by the upper clamping member 31 and the lower clamping member 32 respectively. Figure 6 As shown from left to right: when the lower clamping piece 32 in the vertical clamping mechanism 3 reaches the upper surface of the placement table 11, the clamping assembly in the bag-picking mechanism 5 clamps the lower edge of the wrapping cloth, and then the lower clamping piece 32 is released; the clamping assembly moves to the right with the bag-picking mechanism 5, pulling the wrapping cloth to be laid horizontally, and at this time the vertical clamping mechanism 3 also descends synchronously; when the upper clamping piece 31 in the vertical clamping mechanism 3 reaches the upper surface of the placement table 11 and the clamping assembly pulls the wrapping cloth horizontally to the right side of the placement table 11, the upper clamping piece 31 and the clamping assembly release the wrapping cloth.

[0036] In this embodiment, the bottom end of the vertical guide rail 2 is lower than the placement surface of the packaged objects.

[0037] During the specific implementation, since the upper clamping member 31 in the vertical clamping mechanism 3 needs to be moved to the upper surface of the placement table 11, the vertical guide rail 2 needs to extend below the packaging placement surface.

[0038] In this embodiment, the height difference between the placement surface of the packaged objects and the bottom end of the vertical guide rail 2 is not less than the length of the connecting rod 33 .

[0039] During the specific implementation process, in order to ensure that the lower wrapping cloth is laid flat, the upper clamping member 31 in the vertical clamping mechanism 3 is lowered to the optimal level with the surface on which the packaged object is placed.

[0040] like Figure 1 As shown, in this embodiment, a second frame 4 is included; the second frame 4 includes: a horizontal movable guide rail 41, the first frame 1 is connected to the horizontal movable guide rail 41; a connecting column 42, the bag-picking mechanism 5 is slidably connected to the horizontal movable guide rail 41 through the connecting column 42.

[0041] In a specific implementation process, the horizontal movable guide rail 41 is used to move the bag-picking mechanism 5 and drive the clamping assembly to pull the lower bag cloth.

[0042] like Figure 1 As shown, in this embodiment, the connecting column 42 is rotatably connected to the bag-picking mechanism 5 .

[0043] During the specific implementation, when taking out a package, the mechanical claw of the bag-picking mechanism 5 faces the left frame. After the packaged object is taken out, the bag-picking mechanism 5 rotates so that the mechanical claw faces the right frame, and then the packaged object is sent to the right frame.

[0044] In this embodiment, the bag-picking mechanism 5 rotates horizontally with the connecting column 42 as the rotation axis.

[0045] In the specific implementation process, both vertical and horizontal rotation of the bag-picking mechanism 5 can change the direction of the mechanical claw, but horizontal rotation can better ensure the stability of its clamping of the packaged object. Figure 1 In the illustrated arrangement, the connecting column 42 comprises a fixed section 421, one end of which is slidably connected to the horizontally movable guide rail 41; a motor housed at the other end of the fixed section 421; a rotating section 422, one end of which is connected to the motor; and the other end of the rotating section 422, which is connected to the bag-picking mechanism 5. An inner cavity is defined at the end of the fixed section 421, into which the motor is fixed. The motor drives the horizontal rotation of the rotating section 422, thereby achieving the desired direction of the bag-picking mechanism 5.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations are readily apparent to those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
