Technical Field

[0001] This utility model belongs to the field of packaging machines and relates to a three-station bag picking and transferring device. Background Technology

[0002] A traditional three-station packaging machine includes a bag-picking station, a material-discharging station, and a sealing station, as well as a conveyor mechanism that transports the packaging bags sequentially from the bag-picking station to the material-discharging station and the sealing station. The traditional conveyor mechanism consists of a feed belt. Feed belts are large in size, complex in structure, and expensive. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a three-station bag-picking and bag-transferring device, which has the advantages of simple structure, small footprint, and low cost.

[0004] The objective of this invention is achieved as follows:

[0005] A three-station bag picking and transferring device includes a frame with a feeding platform. The feeding platform has a bag picking station, a material dispensing station, and a sealing station. A bag picking frame is provided on the feeding platform corresponding to the bag picking station. The bag picking frame has a placement slot for placing packaging bags. A bag picking mechanism is provided below the feeding platform. The bag picking mechanism includes a suction cup and a bag picking drive mechanism that drives the suction cup to move up and down. The suction cup is correspondingly arranged with the placement slot. The feeding platform is formed with a suction cup groove for the suction cup to extend out. The device also includes a bag transferring mechanism, which includes a bag transferring bracket with two bag transferring plates and an opening and closing drive mechanism that drives the two bag transferring plates to open and close. The two bag transferring plates are respectively arranged on the upper and lower sides of the feeding platform. A clamping plate is fixed to the opposite end of each of the two bag transferring plates. The bag transferring mechanism also includes a transverse transfer seat with a transverse transfer drive mechanism that drives the bag transferring bracket to move laterally. The feeding platform is formed with a transverse transfer groove corresponding to the clamping plate, and the transverse transfer groove runs through the three stations.

[0006] With the above setup, the suction cup rises through the suction cup groove to pick up the packaging bag in the placement groove, and then moves down to place it on the feeding platform. Next, the opening and closing drive mechanism controls two clamping plates to move closer together to clamp the packaging bag. Then, the lateral drive device drives the clamping plates to move within the lateral chute, thereby conveying the packaging bag from the bag-picking station to the feeding station, or from the feeding station to the sealing station. Compared to conveyor belt feeding, this clamping plate feeding method occupies less space, has a simpler structure, and lower cost.

[0007] The present invention is further configured such that: the bag picking drive mechanism includes a bag picking seat, a servo linear module is fixed on the bag picking seat, the slide of the servo linear module moves up and down, a suction cup frame is fixed on the slide, and a suction cup is fixed on the suction cup frame.

[0008] With the above settings, the suction cup, under the control of the servo linear module, can accurately pick up the packaging bag from below the placement slot, accurately deliver the packaging bag to the feeding platform, and finally reset. The distance of each movement can be adjusted through the servo linear module to adapt to different size requirements.

[0009] The present invention is further configured such that: the bag retrieval rack includes two baffles and a rear baffle, the two baffles and the rear baffle surrounding to form a placement groove.

[0010] The present invention is further configured such that: two guide strips are fixed on the bag-retrieving frame, and adjusting blocks are fixed at the lower ends of the two baffles; the two adjusting blocks are slidably sleeved on the two guide strips; an adjusting screw is also provided between the two adjusting blocks, and an adjusting handle is connected to one end of the adjusting screw.

[0011] With the above settings, the adjustment lever can be turned to move the two adjustment blocks relative to each other, thereby adjusting the distance between the two baffles to accommodate packaging bags of different sizes.

[0012] The present invention is further configured such that: the rear baffle is formed with an adjustment groove, and the bag picker is formed with an adjustment hole, and the adjustment groove and the adjustment hole are connected by bolts for adjustment.

[0013] By loosening the bolts, the relative positions of the adjusting groove and adjusting hole can be moved to adjust the position of the back stop bar, thus adapting to the requirements of packaging bags of different sizes.

[0014] The present invention is further configured such that: there are three suction cups, including two bottom corner suction cups and one top corner suction cup, and the suction cup grooves of the feeding platform corresponding to the two bottom corner suction cups are connected to the transverse movement groove.

[0015] The three suction cups ensure more stable bag removal. Furthermore, the interconnected suction cup slots and transverse sliding slots save space.

[0016] The present invention is further configured such that: the opening and closing drive mechanism includes a servo motor fixed on the bag transfer bracket, the output end of the servo motor is fixed with an output wheel, the bag transfer bracket is also provided with a driven wheel corresponding to the output wheel, the output wheel and the driven wheel are arranged vertically and fitted with a synchronous belt, the synchronous belt is divided into two sub-belts with the axis formed by the axis connecting the axes of the output wheel and the driven wheel, and the two bag transfer plates are respectively fixed on the two sub-belts.

[0017] By fixing the bag-transfer plates to the two belts respectively, the motor can rotate, and the two bag-transfer plates can move closer or further apart to achieve the opening and closing action.

[0018] The present invention is further configured such that: the transverse drive device includes a transverse servo module fixed on the transverse base, and the bag transfer bracket is fixed on the slider of the transverse servo module.

[0019] The present invention is further configured such that: each bag transfer plate is fixed with two clamping plates, and every two upper and lower corresponding clamping plates form a bag clamping group, and the two bag clamping groups correspond to two adjacent workstations.

[0020] With the above setup, the two bag clamping groups can work simultaneously. One group of bag clamping groups will send the packaging bags from the bag picking station to the material feeding station, while the other group will send the packaging bags from the material feeding station to the sealing station. This will improve work efficiency and reduce the lateral movement distance of the bag transfer bracket.

[0021] The present invention is further configured such that a bag pusher is fixed on the side of the bag transfer plate facing the discharge direction.

[0022] The design of the pusher plate allows the sealed packaging bags to be pushed into the collection box at the sealing station, making it convenient to collect the finished products.

[0023] The significant and beneficial technical advantages of this invention compared to existing technologies are as follows: A suction cup rises and passes through a suction cup groove to pick up the packaging bag in the placement groove, then lowers it onto the feeding platform. Next, an opening and closing drive mechanism controls two clamping plates to move closer together and clamp the packaging bag. Then, a lateral drive device drives the clamping plates to move within a lateral groove, thereby conveying the packaging bag from the bag-picking station to the feeding station, or from the feeding station to the sealing station. Compared to conveyor belt feeding, this clamping plate feeding method occupies less space, has a simpler structure, and lower cost. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0032] A three-station bag picking and transferring device includes a frame 1, a feeding platform 2 on the frame 1, a bag picking station 3, a material dispensing station 4, and a sealing station 5 on the feeding platform 2. A bag picking frame 6 is provided on the feeding platform 2 corresponding to the bag picking station, and the bag picking frame 6 has a placement slot 7 for placing packaging bags. A bag picking mechanism 8 is provided below the feeding platform 2. The bag picking mechanism 8 includes a suction cup 9 and a bag picking drive mechanism that moves the suction cup up and down. The suction cup 9 is correspondingly arranged with the placement slot 7. The feeding platform 2 has suction cup grooves 10 for the suction cup 9 to extend out. The device also includes a bag transferring mechanism 1. 1. The bag transfer mechanism includes a bag transfer bracket 12, on which two bag transfer plates 13 are provided and an opening and closing drive mechanism for driving the two bag transfer plates 13 to open and close. The two bag transfer plates 13 are respectively provided on the upper and lower sides of the feeding platform 2. Clamping plates 14 are fixed at the opposite ends of the two bag transfer plates 13. The bag transfer mechanism 11 also includes a transverse transfer seat 15, on which a transverse transfer drive device is provided to drive the bag transfer bracket 12 to move laterally. The feeding platform 2 is formed with a transverse transfer groove 16 corresponding to the clamping plate. The transverse transfer groove 16 passes through three workstations.

[0033] With the above setup, suction cup 9 rises through suction cup groove 10 to pick up the packaging bag 17 in placement groove 7, and then moves down to place it on feeding platform 2. Then, the opening and closing drive mechanism controls the two clamping plates 14 to move closer together to clamp the packaging bag. Next, the lateral drive device drives the clamping plates 14 to move within the lateral groove 16, thereby conveying the packaging bag from bag picking station 3 to feeding station 4, or conveying the packaging bag from feeding station 4 to sealing station 6. Compared to conveyor belt feeding, the clamping plate feeding method occupies less space, has a simpler structure, and lower cost.

[0034] The bag-picking drive mechanism includes a bag-picking seat 18, on which a servo linear module 19 is fixed. A slide 20 of the servo linear module moves up and down, and a suction cup frame 21 is fixed on the slide 20. A suction cup 9 is fixed on the suction cup frame 21. Through this setup, the suction cup 9, under the control of the servo linear module 19, can accurately pick up the packaging bag from below the placement slot 7 and accurately deliver the packaging bag to the feeding platform 2, finally resetting. The distance of each movement can be adjusted via the servo linear module 19 to adapt to different size requirements.

[0035] The bag retrieval rack 6 includes two baffles 22 and a rear baffle 23, which surround and form a placement groove 7.

[0036] Two guide bars 24 are fixed on the bag-retrieving frame 6, and adjusting blocks 25 are fixed to the lower ends of the two baffles 22. The two adjusting blocks 25 are slidably sleeved on the two guide bars 24. An adjusting screw 26 is also provided between the two adjusting blocks 25, and one end of the adjusting screw is connected to an adjusting handle 27. With the above configuration, the adjusting screw 26 can be rotated by adjusting the adjusting handle 27, thereby causing the two adjusting blocks 25 to move relative to each other, and finally adjusting the distance between the two baffles 22 to accommodate packaging bags of different sizes.

[0037] The rear baffle 23 has an adjustment groove 28, and the bag holder 6 has an adjustment hole 29. The adjustment groove 28 and the adjustment hole 29 are connected by bolts for adjustment. With the above settings, the bolts can be loosened and the relative positions of the adjustment groove 28 and the adjustment hole 29 can be moved to adjust the position of the rear baffle 23 to meet the requirements of packaging bags of different sizes.

[0038] There are three suction cups 9, including two bottom corner suction cups and one top corner suction cup. The suction cup grooves of the two bottom corner suction cups on the feeding platform are connected to the transverse movement groove 16. The arrangement of three suction cups 9 makes bag picking more stable. Furthermore, the connection between the suction cup grooves and the transverse movement groove saves space.

[0039] The opening and closing drive mechanism includes a servo motor 30 fixed on the bag transfer bracket. An output wheel 31 is fixed to the output end of the servo motor 30. A driven wheel 32 is also provided on the bag transfer bracket 12 corresponding to the output wheel 31. The output wheel 31 and the driven wheel 32 are arranged vertically and fitted with a synchronous belt 33. The synchronous belt is divided into two sub-belts along the axis connecting the axes of the output wheel 31 and the driven wheel 32. Two bag transfer plates 13 are respectively fixed on the two sub-belts. Preferably, the bag transfer plates are fixed to the sub-belts by clamping blocks 37, thereby enabling the motor to rotate and the two bag transfer plates to move closer or further apart, thus achieving the opening and closing action.

[0040] The transverse drive device includes a transverse servo module 34 fixed on the transverse base 15, and the bag transfer bracket is fixed on the slider 35 of the transverse servo module.

[0041] Each bag transfer plate 13 is fixed with two clamping plates 14. Every two vertically corresponding clamping plates 14 form a bag clamping group, and the two bag clamping groups correspond to two adjacent workstations. With the above configuration, the two bag clamping groups can work simultaneously. One bag clamping group delivers the packaging bag from the bag picking workstation to the material feeding workstation, and the other bag clamping group delivers the packaging bag from the material feeding workstation to the sealing workstation. This can improve work efficiency and reduce the lateral movement distance of the bag transfer bracket.

[0042] A bag-pushing plate 36 is fixed to the side of the bag-transfer plate 13 facing the discharge direction. The design of the bag-pushing plate allows the sealed packaging bags at the sealing station to be pushed into the collection box for easy collection of finished products.

[0043] This invention features a simple structure, small footprint, and low cost.

[0044] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
