[0002] At present, the feeding device for bags in the prior art generally includes a storage rack and a material taking mechanism. The storage rack is used to store bags, and the material taking mechanism is generally a suction cup or a manipulator, etc., which can take the bags on the storage rack and send them to the subsequent stringing machine for processing. The above structure can better realize the feeding function when the bag is hard, but when the bag is soft, the suction cup or manipulator of the prior art does not have enough restraint on the bag, and the soft bag will shake and deviate during the process, resulting in the subsequent inability to smoothly send the bag to the stringing machine. Therefore, when dealing with the feeding of soft bags, the devices of the prior art cannot well realize automatic feeding. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a bag feeding device that can well meet the feeding requirements of relatively soft bags.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a bag feeding device, comprising a storage rack for placing bags, a transfer device connected to the storage rack outlet and a loading device connected to the transfer device outlet, the loading device comprising a rotating rack and a bag picking clamp, the rotating rack is provided with a plurality of bag grooves in the circumference, the bag picking clamp is provided above the rotating rack, the transfer device transfers the bag into the bag groove at its outlet, and the rotating rack delivers the bag to the bag picking clamp by rotating.

[0005] The present invention is further configured as follows: the rotating frame is arranged vertically, the bag body groove is arranged to extend along the rotation radius direction of the rotating frame, and both sides of the bag body groove are connected to the outside.

[0006] The present invention is further configured as follows: the rotating frame includes a plurality of rotating plates coaxially arranged at intervals, and gaps are formed between the plurality of rotating plates; the transfer device includes a conveyor belt, the conveyor belt is used to carry the bag body and drive it to move, and the conveyor belt extends into the gap.

[0007] The present invention is further configured as follows: a raised stopper is provided on the conveyor belt, and the stopper is abutted against the bag body.

[0008] The present invention is further configured as follows: an adjusting groove is arranged beside the bag body groove, an adjusting pin is arranged in the adjusting groove, a limiting portion extending to the bag body groove is arranged on the adjusting pin, and the limiting portion is matched with the bag body in the bag body groove.

[0009] The present invention is further configured as follows: the rotating frame comprises a rotating shaft and a rotating motor driving the rotating shaft to rotate; a plurality of rotating sheets are arranged on the rotating shaft and are positionally adjustable on the rotating shaft.

[0010] The present invention is further configured such that: the material storage rack is arranged tilted toward one side of the outlet.

[0011] The present invention is further configured as follows: a flipping mechanism is provided between the material storage rack and the transfer device, and the flipping mechanism is used to flip the bag body on the material storage rack and place it on the transfer device.

[0012] The present invention is further configured as follows: the flipping mechanism includes a suction cup frame for adsorbing the bag body, a synchronous belt for driving the suction cup frame to move linearly, and a motor B for driving the suction cup frame to rotate.

[0013] The present invention is further configured as follows: an adjustment limit mechanism is provided at the outlet of the storage rack, and the adjustment limit mechanism includes a crossbeam with a track, an adjustment block matched with the track on the crossbeam, and a limit plate and a limit rod fixed on the adjustment block, and the limit plate is matched with the bag body.

[0014] The present invention is further configured as follows: the bag taking clamp is provided with a guide piece in a trumpet-shaped manner facing the bag body, and the guide piece is used to guide the bag body to enter the bag taking clamp.

[0015] In summary, the present invention has the following beneficial effects:

[0016] Compared with the prior art, the present invention provides a rotating frame for feeding the bag body, and the bag body is fed into the bag body groove by a transfer device. Since the groove structure of the bag body groove can well constrain the two sides and the bottom of the bag body, even a very soft bag body can remain stable during the feeding process. After the bag body is rotated upward, the bag clamp can stably clamp the top position of the bag body leaking out of the bag body groove to complete the feeding.

[0017] The rotating frame of the present invention is also provided with an adjusting groove, an adjusting pin and a limiting portion structure. By changing the positions of the adjusting pin and the limiting portion, the groove depth of the bag body groove can be changed, and the bag bodies of different lengths can be adapted. At the same time, the rotating frame is also composed of a plurality of rotating plates, and the positions of the rotating plates on the rotating shaft can also be adjusted, thereby adapting to bags of different widths; it can meet the use of bags of different specifications and has strong versatility.

[0018] The present invention provides a transfer device as a transition between the rotating frame and the storage rack. When the bag body is just taken off the storage rack by the flipping mechanism, the softer bag body still shakes, so it needs to be placed flat on the conveyor belt of the transfer device first. The bag body becomes stable by relying on the conveying time on the conveyor belt, and then it can be smoothly sent into the bag body slot, thereby realizing the stable transportation of the softer bag body.

[0019] The present invention also provides an inclined storage rack. Since a softer bag body is prone to bending and deformation when moving laterally, an inclined setting is adopted to use gravity to allow the bag body to naturally lean towards the outlet, thereby ensuring that the bag body is always located at the outlet of the storage rack without undergoing significant deformation.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0027] This embodiment discloses a bag feeding device, such as Figure 1-5As shown, it includes a storage rack 1 for placing bags, a transfer device 2 connected to the outlet of the storage rack 1, and a loading device 3 connected to the outlet of the transfer device 2. The loading device 3 includes a vertical rotating rack 4 and a bag taking clamp 5 arranged above the rotating rack. The rotating rack 4 is circumferentially provided with a plurality of bag body grooves 6. The transfer device 2 transfers the bag body to the bag body groove 6 at its outlet, and the rotating rack 4 delivers the bag body to the bag taking clamp 5 by rotating. Through the above structure, for a softer bag body 17, the bag body groove 6 can well restrain and support the two sides and the bottom of the bag body 17. At the same time, the bottom of the bag body 17 has a folded part when it is not unfolded, which is thicker and has a certain opening force. Therefore, the bottom of the bag body 17 can be supported in the bag body groove 6, ensuring that the soft bag remains stable during transportation and can be accurately clamped by the bag taking clamp 5 at the top position. At the same time, the bag body groove 6 is provided with an opening in the bag taking direction of the bag taking clamp 5, so after the bag taking clamp 5 clamps the bag body, it can directly move to the rope threading machine 16 to take the bag, so that the bag body 17 is directly pulled out from the side of the bag body groove 6, and the bag body 17 is smoothly sent into the rope threading machine 16. In this embodiment, the bag taking principle of the bag taking clamp 5 is to clamp the bag body with the clamp block through the cylinder, and then move horizontally to drive the bag body to the next station in the rope threading machine.

[0028] Further, see Figure 3 In order to ensure that the transfer device 2 can smoothly transfer the bag 17 to the bag slot 6, the rotating frame 4 includes a plurality of rotating plates 7 coaxially arranged at intervals, and a gap 8 is formed between the plurality of rotating plates 7. The transfer device 2 includes a conveyor belt 9, which is used to carry the bag and drive it to move, and the conveyor belt 9 extends into the gap 8. The bag can extend into the rotating plate along with the conveyor belt 9, and then the bag 17 enters the bag slot 6. The advantage of this is that the part of the bag entering the bag slot 6 is actually supported by the conveyor belt, and is not easy to deform in the process of entering the bag slot 6, ensuring that the soft bag can also smoothly enter the bag slot 6.

[0029] Further, a raised stopper 10 is provided on the conveyor belt 9, and the stopper 10 is matched with the bag body. The stopper 10 is provided to push the bag body, thereby ensuring the interval between the bag bodies.

[0030] Further, see Figure 4 Since the bag body has different lengths, an adjustment slot 11 is provided beside the bag body slot 6, and an adjustment pin 12 is provided in the adjustment slot 11. The adjustment pin 12 is provided with a limiter 13 extending to the bag body slot 6, and the limiter 13 is matched with the bag body in the bag body slot 6. By changing the position of the adjustment pin 12, the position of the limiter 13 can be adjusted synchronously, and the bottom of the bag body will hit the limiter 13, thereby changing the depth of the bag body that can enter the bag body slot 6. In this way, no matter whether the bag body is long or short, its top can be extended out of the bag body slot 6, so that the bag taking clip 5 can clamp it.

[0031] Furthermore, the rotating frame 4 includes a rotating shaft 401 and a rotating motor 402 for driving the rotating shaft 401 to rotate. A plurality of rotating plates 7 are arranged on the rotating shaft 401 and the positions of the rotating plates 7 are adjustable. Through the above-mentioned structural arrangement, the positions of the rotating plates 7 on the rotating shaft 401 can be adjusted for bags of different widths. When the bag is narrow, the rotating plates 7 are adjusted closer, and when the bag is wide, the rotating plates 7 are adjusted farther away. If necessary, the number of rotating plates 7 can be increased or decreased, but it should be noted that a gap 8 for the conveyor belt 9 to enter is always left. In this way, the rotating frame 4 can provide stable restraint support regardless of the width of the bag.

[0032] Furthermore, the storage rack 1 is tilted toward the outlet side thereof. Since the softer bag is prone to bending and deformation when moving horizontally, the tilted setting is adopted to use gravity to make the bag naturally lean toward the outlet, so that the bag can be always located at the outlet of the storage rack without significant deformation.

[0033] Further, see Figure 5 A flipping mechanism 14 is provided between the storage rack 1 and the transfer device 2, and the flipping mechanism 14 is used to flip the bag on the storage rack 1 and place it on the transfer device 2. The flipping mechanism 14 includes a suction cup frame 1401 for adsorbing the bag, a synchronous belt 1402 for driving the suction cup frame 1401 to move linearly, and a motor B1403 for driving the suction cup frame 1401 to rotate. Through the above structure, the direction of the synchronous belt 1402 is set to be consistent with the tilt direction of the storage rack 1, so that the movement of the synchronous belt 1402 can drive the suction cup frame 1401 to approach the bag 17 on the storage rack 1 in parallel, and then the suction cup is used to adsorb the bag, and then the synchronous belt drives the suction cup frame 1401 to pull out the adsorbed bag, and the motor B1403 is used to turn the bag to a position parallel to the conveyor belt 9 of the transfer device, and then the synchronous belt continues to tilt downward, and the suction cup releases the bag, and the bag is placed flat on the conveyor belt. Since the softer bag body still shakes when the bag body is just taken off the storage rack by the flipping mechanism, the flipping mechanism 14 and the transfer device 2 are set to allow the soft bag to be laid flat for a transition after being taken off the storage rack 1, and after it is stabilized by gravity, it can be smoothly sent to the bag body slot 6 by the transfer device 2. At the same time, in addition to being set horizontally, the transfer device 2 can also feed materials at a certain inclined angle within the range of the angle a18, which can be adjusted according to the spatial layout of the actual device.

[0034] Furthermore, an adjustment and limiting mechanism 15 is provided at the exit of the storage rack 1. The adjustment and limiting mechanism 15 comprises a crossbeam 1501 with a track, an adjustment block 1502 matched with the track on the crossbeam, and a limit plate 1503 and a limit rod 1504 fixed on the adjustment block 1502. The limit rod 1504 connects the limit plate 1503 and the adjustment block 1502, and the limit plate 1503 is matched with the bag body. The limit plate 1503 is used to block the bag body at the exit to prevent it from escaping by itself, and when pulled by the flip mechanism, the bag body can smoothly escape from the blockage of the limit plate 1503 by virtue of its deformation. The adjustment block 1502 and the crossbeam 1501 are used to adjust the width to adapt to bags of different specifications. At the same time, the limiting rod 1504 can be further provided with a pressing wheel and other components not shown in the figure to limit the bag body, and the pressing wheel can also block the bag body when the bag body is in the material storage state, and when the bag body is pulled, the pressing wheel can rotate to allow the bag body to escape. It cooperates with the limiting plate 1503 to better limit the bag body on the material storage rack 1, and also facilitates the unloading of the bag body from the material storage rack 1.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
