Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag stringing, in particular to an automatically lifted packaging bag stringing machine. Background Art

[0002] After production, packaging bags usually need to be threaded to improve their portability.

[0003] However, the current equipment used for stringing packaging bags is generally used for paper packaging bags. In this type of equipment, paper packaging bags are usually stacked front to back and moved horizontally in sequence to perform stringing work on the front and back sides. However, this equipment cannot be transferred to flexible packaging bags for the following reasons: flexible packaging bags are generally stacked up and down, and the existing front and back stacking pushing and moving material stringing methods for paper packaging bags are not applicable. In addition, the rope in the flexible packaging belt is generally inserted horizontally, which is more difficult to locate and perform stringing work. Therefore, it is necessary to improve and design the existing equipment. Utility Model Content

[0044] Reference Figures 1-12 According to an embodiment of the present invention, an automatic lifting packaging bag stringing machine includes a machine platform 11, such as Figure 1 As shown, the machine 11 is provided with a bag supporting assembly 101, a bag transverse movement assembly 102 and a bag string threading assembly 103. The bag supporting assembly 101 is used to support the packaging bags in a stacked state, and cooperate with the bag transverse movement assembly 102 to move the packaging bags 111 transversely into the bag string threading assembly 103 for stringing.

[0045] like Figure 2 As shown, the bag supporting assembly 101 includes a lifting platform 51 arranged on the machine 11, a No. 1 cylinder is fixedly provided in the machine 11, and the piston rod in the No. 1 cylinder is upwardly connected to the bottom surface of the lifting platform 51, the machine 11 is also provided with a baffle distributed around the lifting platform 51, and the machine 11 is also provided with a telescopic rod connected to the bottom surface of the lifting platform 51.

[0046] The bag body transverse movement assembly includes a No. 1 slide module 61 connected to the machine 11 through a No. 1 fixed frame, a No. 2 slide module 62 is fixed on the No. 1 slider that can slide left and right in the No. 1 slide module 61, a No. 2 cylinder 63 is fixed on the No. 2 slider that can slide back and forth in the No. 2 slide module 62, and a lifting frame 64 is fixed on the piston rod in the No. 2 cylinder 63, and a plurality of No. 1 vacuum suction cups 65 are installed in the lifting frame 64.

[0047] In this embodiment, the baffles include side baffles 53 installed on the left and right sides of the lifting platform 51, a rear baffle 54 installed on the rear side of the lifting platform 51, and a front baffle 55 installed on the front side of the lifting platform 51. The side baffles 53 and the rear baffle 54 are both provided with two groups with gaps between them, and the front baffle 55 is only provided with one and is widened laterally to prevent the staff operating at the front side of the machine 11 from accidentally touching the packaging bags on the lifting platform 51.

[0048] The bag supporting assembly and the bag transverse moving assembly transfer the packaging bag as follows:

[0049] First, the packaging bags are stacked on the lifting platform 51 and limited by the baffle to avoid tilting. When the lifting frame 64 is on the upper side of the lifting platform 51, the lifting frame 64 descends until the No. 1 vacuum suction cup 65 is attached to the uppermost packaging bag on the lifting platform 51. Then, negative pressure is generated in the No. 1 vacuum suction cup 65 and the packaging bags are adsorbed. After that, the lifting frame 64 moves to the left after moving to the upper side of the baffle, and then the No. 2 slider that can slide back and forth can transfer the packaging bag adsorbed by the No. 1 vacuum suction cup 65 to the bag body threading assembly 103, and perform the threading work.

[0050] Furthermore, in order to enable the lifting platform 51 to automatically rise a certain distance after a certain amount of packaging bags on the lifting platform 51 are consumed, so as to avoid the topmost packaging bags being on the lower side of the stroke of the No. 1 vacuum suction cup 65, the left and right side baffles 53 are respectively equipped with opposing photoelectric sensors 56. When the receiver in the opposing photoelectric sensor 56 receives the light signal emitted by the transmitter, it indicates that the topmost packaging bags are in a too low position. At this time, the No. 1 cylinder causes the lifting platform 51 to move up a certain distance to cover the transmitter.

[0051] In this embodiment, the bag threading assembly includes a suction bin 21, a suction square tube 24 and a locking plate 25 which are arranged upward in sequence and are arranged above the machine 11 through a No. 1 positioning assembly;

[0052] There are two suction bins 21 distributed on the left and right. A horizontal plate 22 is fixed on the top of the two suction bins 21. The horizontal plate 22 on the upper side of the suction bin 21 is provided with a plurality of first suction holes 23 that pass through the upper and lower sides and are connected to the suction bin 21.

[0053] The locking plate 25 is provided with two second vacuum suction cups 26 which are vertically installed and distributed on the left and right sides;

[0054] A negative pressure groove is provided in the square suction pipe 24, and a plurality of second suction holes 34 are provided on the left and right edges of the upper and lower sides of the negative pressure groove.

[0055] The suction bin 21, the suction square tube 24 and the second vacuum suction cup 26 can all generate negative pressure to adsorb the packaging bag, and the solution for generating negative pressure therein is existing technology, which can adopt mechanical exhaust or direct connection to a vacuum pump, etc., which will not be elaborated here.

[0056] The packaging bag includes an upper bag surface and a lower bag surface, and both the upper bag surface and the lower bag surface are provided with rope threading holes. The automatically lifting packaging bag rope threading machine is used to pass the rope through the rope threading hole. The left and right edges of the packaging bag opening are respectively provided with arc grooves. Before the rope threading work is performed and the packaging bag is clamped, the suction square tube 24 is horizontally inserted into the packaging bag. At this time, the left and right edges of the upper and lower side surfaces outside the packaging bag are respectively adsorbed by the left and right No. 2 vacuum suction cups 26 and the left and right No. 1 suction holes 23, while the left and right edges of the upper and lower side surfaces inside the packaging bag are respectively adsorbed by the No. 2 suction holes 34 distributed up and down and left and right. There is a certain gap between the horizontal plate 22 and the suction square tube 24, and between the suction square tube 24 and the No. 2 vacuum suction cup 26, so that the rope threading hole is in an expanded state, which is convenient for rope threading.

[0057] The size of the gap can be changed under the control of the No. 1 positioning component, thereby facilitating the negative pressure clamping of the packaging bag and avoiding the occurrence of air adsorption after the packaging bag is in place. Specifically, the No. 1 positioning mechanism can control the upper and lower positions of the suction bin 21, the suction square tube 24 and the locking plate 25, and can control the front and rear positions of the suction square tube 24. The specific negative pressure adsorption process of the packaging bag is as follows:

[0058] After the packaging bag is transported to the transverse plate 22 by the bag body transverse movement assembly, suction is generated in the No. 1 suction hole 23 and the left and right edges of the outer lower side surface of the packaging bag are locked. After the suction square tube 24 moves backward, the locking plate 25 sinks and causes suction to be generated in the No. 2 vacuum suction cup 26 and the left and right edges of the outer upper side surface of the packaging bag. Then, the locking plate 25 is lifted up and the packaging bag is opened. Then, the suction square tube 24 enters the packaging bag forward. Then, the locking plate 25 and the suction square tube 24 sink a certain distance until the upper and lower sides of the packaging bag are attached to the upper and lower sides of the suction square tube 24. Then, negative pressure is generated in the suction square tube 24 and locks the left and right edges of the upper and lower sides of the packaging bag through the No. 2 suction hole 34. Then, the locking plate 25 and the suction square tube 24 rise to expand the rope threading hole in the packaging bag. Specifically, the locking plate 25 moves up a distance of two units, and the suction square tube 24 moves up a distance of one unit to facilitate rope threading.

[0059] In addition, the bag body rope threading assembly also includes two rope threading guns 91 arranged vertically and mounted on the upper side of the machine 11 through a No. 2 positioning mechanism, and two No. 1 pneumatic clamps 84 arranged vertically and mounted on the upper side of the machine 11 through a No. 3 positioning mechanism, and also includes a rope supply assembly for supplying the rope into the rope threading gun 91. The No. 2 positioning mechanism is used to control the left and right positions of the rope threading gun 91 and the upper and lower spacing between the rope threading guns 91, and the No. 3 positioning mechanism is used to control the left and right positions of the No. 1 pneumatic clamps 84 and the upper and lower spacing between the No. 1 pneumatic clamps 84, and the No. 1 pneumatic clamps 84 and the rope threading gun 91 are respectively mounted on the left and right sides of the suction warehouse 21.

[0060] The specific rope threading process in this embodiment is as follows:

[0061] First, the packaging bag on the top layer in the bag support assembly will be transferred to the bag string assembly by the bag transverse movement assembly. Then, the packaging bag will be sucked and the string hole in it will be in an expanded state. Then, the string gun 91 on the right side of the packaging bag will clamp the rope (specifically, the two ends of a rope are clamped by the upper and lower string guns 91, and the middle part of the rope hangs naturally). Then, the string gun 91 will go to the left and penetrate the two upper and lower string holes in the packaging bag (the suction warehouse 21 and the suction warehouse 21). The upper and lower positions of the square tube 24 and the locking plate 25 can be adjusted to adapt to the upper and lower positions of the rope threading gun 91), and then the No. 1 pneumatic clamp 84 moves horizontally and clamps the end of the rope. After that, the rope threading gun 91 unlocks the rope and moves right to complete the single-sided rope threading of the packaging bag. That is, at this time, the suction warehouse 21, the suction square tube 24 and the No. 1 vacuum suction cup 26 can no longer be adsorbed, and the No. 1 pneumatic clamp 84 no longer clamps, so that the rope-threaded packaging bag falls naturally.

[0062] In this embodiment, there is only one rope supply assembly and it is arranged on the right side of the suction bin 21. The rope supply assembly includes a No. 3 slide module 27 connected to the machine 11 through a No. 2 fixed frame. The No. 3 slider in the No. 3 slide module 27 that can be raised and lowered is fixed with a No. 2 pneumatic clamp 28 that can clamp the rope. The No. 3 slide module 27 on the upper side of the No. 3 slider stroke (specifically, the slide seat in the No. 3 slide module 27) is also fixed with a rope threading plate 29. The rope threading plate 29 is provided with a through hole that passes through the top and bottom for the rope to pass through. The through hole serves to limit the rope.

[0063] In addition, the rope supply assembly also includes a No. 4 slide module 30 connected to the machine 11 through a No. 3 fixing frame. The No. 4 slider that can slide back and forth in the No. 4 slide module 30 is equipped with two No. 3 pneumatic clamps 31 distributed up and down through a No. 1 connecting plate. The No. 2 pneumatic clamp 28 is used to deliver the rope to the No. 3 pneumatic clamp 31, and the No. 3 pneumatic clamp 31 is used to deliver the rope forward to the rope threading gun 91.

[0064] In order to enable the rope to be cut automatically, the rope supply assembly also includes a No. 3 cylinder 32 fixed on the No. 3 slide module 27 through the No. 2 connecting plate. The piston rod in the No. 3 cylinder 32 is equipped with a knife seat, and the knife seat is connected to the No. 1 connecting plate by sliding back and forth. The knife seat is equipped with a pneumatic scissors 33, and the knife head in the pneumatic scissors 33 is facing the rope after passing through the rope threading plate 29.

[0065] In order to enable the rope threading gun 91 to automatically cooperate with the rope supply assembly, the specific structure of the rope threading gun 91 is that the rope threading gun 91 includes a gun seat 92, which is fixedly installed. A sleeve 93 is fixed on the gun seat 92, and a groove is provided on the rear side of the curved surface of the sleeve 93 so that the vertical side surface of the bottom of the sleeve 93 is exposed, and a push rod 94 is connected to the sleeve 93 for sliding left and right. A small cylinder 95 is also fixed on the gun seat 92, and a small piston rod in the small cylinder 95 is connected to the push rod 94.

[0066] The specific rope supply process of the rope supply component for the rope threading gun 91 is as follows:

[0067] After the rope passes through the rope threading plate 29 downward, it is clamped by the No. 2 pneumatic clamp 28 on the uppermost side (the lower end of the rope is on the lower side of the No. 2 pneumatic clamp 28), and then the No. 2 pneumatic clamp 28 moves downward (under the control of the No. 3 slide module 27) and pulls the rope downward. After the No. 2 pneumatic clamp 28 is on the lower side of the two No. 3 pneumatic clamps 31, the No. 4 slide block drives the No. 3 pneumatic clamp 31 forward, and then the No. 3 pneumatic clamp 31 on the lower side clamps the rope and makes the lower end of the rope be on the lower side of the No. 3 pneumatic clamp 31, and then the No. 2 pneumatic clamp 28 opens and moves upward (the movement of the No. 2 pneumatic clamp 28 after opening will not interfere with the No. 3 pneumatic clamp 31), and then Then, the rope is clamped and dragged downward for a short distance, so that the No. 2 pneumatic clamp 28 is located below the pneumatic scissors 33. Then, the No. 3 cylinder 32 controls the pneumatic scissors 33 to move forward, and makes the pneumatic scissors 33 retreat after cutting the rope, so that the upper end of the rope is located above the No. 2 pneumatic clamp 28. Then, the No. 2 pneumatic clamp 28 moves downward again until it is close to the No. 3 pneumatic clamp 31 on the upper side. Then, the No. 3 pneumatic clamp 31 on the upper side can clamp the rope in the No. 2 pneumatic clamp 28, and make the upper end of the rope be above the No. 3 pneumatic clamp 31 on the upper side. Then, the No. 2 pneumatic clamp 28 is released and moves upward, and the No. 3 pneumatic clamp 31 completes the clamping of the two ends of a rope.

[0068] Afterwards, the No. 2 positioning mechanism controls the longitudinal distance between the two rope threading guns 91 to reach the maximum, and then the No. 4 slider controls the No. 3 pneumatic clamp 31 to move forward and make the No. 3 pneumatic clamp 31 between the two rope threading guns 91, and make the two ends of the rope enter the notches in the upper and lower rope threading guns 91, and then the small cylinder 95 controls the movement of the push rod 94, and makes the two ends of the rope pressed in the notches, and then the No. 3 pneumatic clamp 31 opens, and the No. 4 slider and the No. 3 pneumatic clamp 31 reset backward, at this time completing the rope supply process of fixing a section of rope in the rope threading gun 91, and then the rope threading guns 91 can adjust the distance again to adapt to the distance between the upper and lower rope threading holes in the packaging bag.

[0069] The No. 1 positioning mechanism includes a No. 4 fixing frame fixed to the machine table 11, and the No. 4 fixing frame is equipped with a fixing plate 41, a mounting plate 43 is slidably connected to the front side of the fixing plate 41, and a No. 4 cylinder 42 for controlling the up and down position of the mounting plate 43 is installed on the front side of the fixing plate 41, a No. 1 slide bar is slidably connected to the mounting plate 43, and the suction square tube 24 is connected to the front end of the No. 1 slide bar, and a No. 5 cylinder 44 for controlling the front and rear position of the No. 1 slide bar is fixed on the mounting plate 43;

[0070] A T-shaped plate 45 is fixed on the mounting plate 43, and a No. 2 slide bar is connected to the T-shaped plate 45 for sliding forward and backward, and a cylinder seat 46 is connected to the front end of the No. 2 slide bar. A No. 6 cylinder 47 is fixed on the cylinder seat 46, and the locking plate 25 is fixed to the lower end of the piston rod in the No. 6 cylinder 47. A No. 7 cylinder 48 for controlling the front and rear position of the No. 2 slide bar is also fixed on the back side of the T-shaped plate 45.

[0071] The No. 1 positioning mechanism also includes a No. 3 slide bar fixed on the machine platform 11, and a slide seat 49 is slidably connected to the No. 3 slide bar. A horizontal plate is fixed on the slide seat 49 through a vertical rod, and the two suction bins 21 are fixed on the horizontal plate. A No. 8 cylinder 50 is fixed on the machine platform 11 for controlling the lifting of the slide seat 49.

[0072] That is, the No. 4 cylinder 42 can control the upper and lower positions of the mounting plate 43, the No. 5 cylinder 44, the locking plate 25 and the suction square tube 24. The locking plate 25 can be independently adjusted in the upper and lower positions under the control of the No. 6 cylinder 47, while the No. 7 cylinder 48 and the No. 5 cylinder 44 can independently control the front and rear positions of the locking plate 25 and the suction square tube 24. The No. 8 cylinder 50 can control the upper and lower positions of the suction bin 21 and the horizontal plate 22. It should be additionally noted that the mounting groove in the fixed plate 41 for accommodating the No. 5 cylinder 44 has a margin for the upper and lower positions to avoid interference between the No. 5 cylinder 44 and the fixed plate 41 when the mounting plate 43 moves up and down.
