Description

Technical Field

[0001] This utility model relates to a swing-type finished product transfer mechanism for a vertical bag making and packaging integrated machine. Background Technology

[0002] The existing vertical bag making and packaging machine has an unreasonable structure. When the irregularly shaped bags are sent out, a vacuum suction cup moves horizontally to remove the packaged products from the film that is conveyed vertically downward (by breaking the multiple point connections between the packaged products and the film). Then, the packaged products fall freely under their own weight. As a result, the falling packaged products are messy and must be sorted manually for subsequent processing steps (such as stacking, boxing, etc.). Utility Model Content

[0003] The purpose of this utility model is to provide a swing-type finished product transfer mechanism for a vertical bag-making and packaging machine. This swing-type finished product transfer mechanism can quickly, smoothly, and accurately complete the removal and placement of packaged finished products. The technical solution adopted is as follows:

[0004] A swing-type finished product transfer mechanism for a vertical bag-making and packaging integrated machine includes a frame, a reciprocating swing unit, and at least one vacuum suction cup. The frame has a bag-picking station and a bag-placing station. The reciprocating swing unit is installed at the bottom of the frame, and all vacuum suction cups are mounted on the reciprocating swing unit. The mechanism is characterized by further including a swing stability limiting unit. The frame has supporting side plates. The reciprocating swing unit includes a rotating shaft, a drive swing rod, a swing frame, and a swing drive component. The rotating shaft is mounted on the supporting side plate, and its extension direction is parallel to the film. The swing frame is mounted on the rotating shaft, and all vacuum suction cups are mounted on... On the swing frame, an active swing rod is installed at one end of a rotating shaft, and a swing drive is installed on a supporting side plate. The swing drive has an actuating end, which is connected to the active swing rod and drives the active swing rod to rotate around the rotating shaft, causing all vacuum suction cups to swing back and forth between the bag picking station and the bag placing station. The swing frame includes a swing side plate, a bushing, and a rotating shaft. The swing side plate is fixed on the rotating shaft, the bushing is installed at the end of the swing side plate, and the rotating shaft is rotatably set inside the bushing. The swing stability limiting unit includes a limiting rod and a limiting swing plate. One end of the limiting swing plate is connected to one end of the rotating shaft, and the two ends of the limiting rod are respectively hinged to the other end of the limiting swing plate and the supporting side plate. The function of the swing stability limiting unit is to ensure that all vacuum suction cups extend towards the film when the swing frame's rotation axis rotates to the front of the bag picking station, so as to pick up the packaged product. During the swing, it ensures the stability of the vacuum suction cups' movement and avoids deformation caused by excessive force during the process of breaking the multiple point connections between the packaged product and the film, which would affect the quality of the packaged product. When the swing frame's rotation axis rotates to the top of the bag placing station, it ensures that all vacuum suction cups extend vertically downward to accurately place the packaged product (ensuring that the position and angle of the packaged product are accurate when it is placed).

[0005] In a preferred embodiment, the swing drive component is a cylinder, and the actuating end is the piston shaft of the cylinder, which is connected to the active swing rod.

[0006] In a preferred embodiment, the swing-type finished product transfer mechanism of the vertical bag making and packaging integrated machine further includes a finished product delivery device, which is a conveyor belt. The conveyor belt is located below the reciprocating swing unit and passes through the bag placement station.

[0007] The advantages of this invention compared to the prior art are that the reciprocating swing unit drives all vacuum suction cups to pick up the packaged product at the bag-picking station and swing it, breaking the connection points between the packaged product and the film in sequence, causing the packaged product to detach from the film. The reciprocating swing unit then drives all vacuum suction cups to swing to the bag-laying station to place the packaged product, which is lying flat. The swing stability limiting unit ensures the stability of the vacuum suction cups' movements, preventing deformation caused by excessive force during the process of breaking the multiple point connections between the packaged product and the film, which would affect the quality of the packaged product. Therefore, the combination of the two can accurately place the packaged product on the bag-laying station, and can quickly complete the removal and flattening of the packaged product.

[0017] like Figure 1-9As shown, the swing-type packaging finished product transfer mechanism of the vertical bag making and packaging integrated machine in one embodiment of this application includes a frame 4, a reciprocating swing unit 1, and at least one vacuum suction cup 2. The frame 4 is provided with a bag picking station A and a bag placing station B. The reciprocating swing unit 1 is installed at the bottom of the frame 4, and all vacuum suction cups 2 are installed on the reciprocating swing unit 1. The reciprocating swing unit 1 drives all vacuum suction cups 2 to swing back and forth between the bag picking station A and the bag placing station B.

[0018] like Figure 1-3 As shown, in an optional embodiment of this application, the frame 4 has a supporting side plate 401, and the reciprocating swing unit 1 includes a rotating shaft 101, an active swing rod 102, a swing frame 103, and a swing drive 104. The rotating shaft 101 is mounted on the supporting side plate 401 and extends in a direction parallel to the film. The swing frame 103 is mounted on the rotating shaft 101, and all vacuum suction cups 2 are mounted on the swing frame 103. The active swing rod 102 is mounted on one end of the rotating shaft 101, and the swing drive 104 is mounted on the supporting side plate 401 and has an actuating end. The actuating end is connected to the active swing rod 102 and drives the active swing rod 102 to rotate around the rotating shaft 101, thereby driving all vacuum suction cups 2 to reciprocate between the bag taking station A and the bag placing station B.

[0019] like Figure 1 , 3 As shown, in an optional embodiment of this application, the reciprocating swing unit 1 further includes a swing stability limiting unit 105. The swing frame 103 includes a swing side plate 1031, a bushing 1032, and a rotating shaft 1033. The swing side plate 1031 is fixed on the rotating shaft 101. The bushing 1032 is installed at the end of the swing side plate 1031. The rotating shaft 1033 is rotatably disposed in the bushing 1032. The swing stability limiting unit 105 includes a limiting rod 1051 and a limiting swing plate 1052. One end of the limiting swing plate 1052 is connected to one end of the rotating shaft 1033. The two ends of the limiting rod 1051 are respectively hinged to the other end of the limiting swing plate 1052 and the supporting side plate 401.

[0020] like Figure 2 As shown, in one alternative embodiment of this application, the swing drive 104 is a cylinder, and the actuating end is the piston shaft of the cylinder, which is connected to the active swing rod 102.

[0021] like Figure 1-3 As shown, in an optional embodiment of this application, the swing-type finished product transfer mechanism of the vertical bag making and packaging integrated machine further includes a finished product delivery device, which is a conveyor belt 3. The conveyor belt 3 is located below the reciprocating swing unit 1 and passes through the bag placement station B.

[0022] like Figure 3As shown, in one alternative embodiment of this application, the conveyor belt 3 extends at an angle from below the bag-taking station A toward below the bag-laying station B.

[0023] like Figure 3 As shown, in one alternative embodiment of this application, an inclined slide plate 301 is installed at the outlet of the conveyor belt 3.

[0024] like Figure 1 As shown in an optional embodiment of this application, the frame 4 further includes a pad 402, which is disposed vertically at the bag-picking station A. Thus, when the vacuum suction cup 2 picks up a bag, the pad 402 provides support for the packaged product, preventing it from moving outwards and facilitating bag picking by the vacuum suction cup 2.

[0025] The following is combined Figure 1-9 The working process of this embodiment is described below:

[0026] The packaged product 5 and film 6, which are moving from top to bottom, stop moving, and the packaged product 5, which is waiting to be bagged, stops at the bag-taking station A.

[0027] When picking up a bag, the swing drive 104 drives the active swing arm 102 to rotate around the rotating shaft 101, moving all the vacuum suction cups 2 to the bag picking station A. Each vacuum suction cup 2 picks up the corresponding packaged product 5 (in a vertical position). Then, the swing drive 104 drives the active swing arm 102 to rotate in the opposite direction around the rotating shaft 101, moving all the vacuum suction cups 2 to the bag placing station B. Each vacuum suction cup 2 carries the corresponding packaged product 5, detaches from the film 6, and moves to the bag placing station B. At this time (i.e., when placing the cup), the packaged product 5 is in a flat position, and each vacuum suction cup 2 stops working, allowing the corresponding packaged product 5 to fall flat onto the conveyor belt 3. In this way, the packaged products 5 are distributed regularly and orderly, making it easy for the conveyor belt to send them to the next station for processing (such as stacking, packaging, etc.).

[0028] Because the packaged product 5, moving vertically downwards, is connected to the film 6 by at least one connection point, it will not fall off the film 6. All vacuum suction cups 2 of the swing-type packaged product transfer mechanism pick up the packaged product 5 at the bag-picking station A and swing it, sequentially breaking the connection points between the packaged product 5 and the film 6. Only then will the packaged product 5 detach from the film 6. When the reciprocating swing unit 1 drives all vacuum suction cups 2 to swing to the bag-laying station B, all vacuum suction cups 2 stop working, and the packaged product 5, which is lying flat, is placed down. In this way, the packaged product 5 can be accurately placed on the bag-laying station B (i.e., the packaged product 5 is in a preset position and angle). Due to the assistance of the swing stability limiting unit 105, the vacuum suction cups 2 can avoid the influence of large tensile forces during the swinging and breaking of the connection points, stably completing the swinging action and ensuring that the quality of the packaged product 5 is not adversely affected by indecisive breaking.
