Description

Technical Field

[0001] This utility model relates to automated production line equipment, and more specifically, to a fully automatic linear spout bag filling and screw-on machine. Background Technology

[0002] In recent years, with the rapid development of the packaging industry and the increasing demand from consumers for portable and environmentally friendly packaging, spout pouch packaging has gradually become the mainstream in the market. Due to its advantages of being lightweight, having good sealing properties, being easy to carry, and suitable for various liquid and semi-liquid products, spout pouch packaging is widely used in food, beverages, daily chemicals, and many other fields. To meet market demand, various types of spout pouch filling equipment have emerged, among which rotary equipment is the most common.

[0003] Currently, rotary spout bag filling and capping machines are widely used due to their relatively mature technology and stable performance. While rotary equipment can achieve a high level of automation, some shortcomings have also been revealed in actual production:

[0004] (1) Rotary spout bag filling and capping machines typically employ complex rotary mechanisms, resulting in a relatively complex mechanical structure. This complex design not only increases manufacturing costs but also raises the difficulty of maintenance and repair.

[0005] (2) In actual production, rotary equipment is prone to bag jamming, especially when the bag supply or conveying system is unstable. At the junction of the bag conveying mechanism from the straight section to the rotary station, bag jamming is very likely to occur, which will cause the production line to stop, reduce production efficiency, and increase the uncertainty in the production process.

[0006] (3) Rotary equipment has poor adaptability to spout bags of different sizes and specifications. When switching production lines or changing production specifications, it may take a long time to adjust and modify.

[0007] To address the aforementioned issues, it is necessary to provide a fully automatic linear spout bag filling and screw-on machine to solve these problems. Utility Model Content

[0010] Furthermore, the bag moving plate is provided with multiple bag openings at equal intervals along the straight conveying track.

[0011] Furthermore, the filling mechanism includes multiple filling stations equally spaced along the linear conveying track; the capping mechanism includes multiple capping stations equally spaced along the linear conveying track; the spacing between the multiple filling stations, the spacing between the multiple capping stations, the spacing between the multiple bag openings, and the spacing by which the equally spaced bag separating mechanism divides the spout bags are all equal; the number of filling stations and capping stations are equal.

[0012] Furthermore, the linear drive component includes a first drive motor, a first slide rail arranged along the linear conveying track, and a first slider arranged on the first slide rail; the first slider is connected to one end of the card bag moving plate via a connecting rod.

[0013] Furthermore, the bag-moving mechanism also includes a telescopic drive component, and the bag-moving plate also includes a second slide rail and a second slider disposed on the second slide rail along the direction of the linear conveying track; the output shaft of the telescopic drive component is fixedly connected to the second slider, and the telescopic drive component drives the bag-moving plate to move back and forth in a direction perpendicular to the second slide rail.

[0014] Furthermore, the connecting rod is rotatably connected to the first slider and the card bag moving plate, respectively.

[0015] Furthermore, the bag conveying mechanism includes a bag guide plate and a bag pushing component. One end of the bag guide plate is open, and the other end is connected to the bag conveying track inlet of the linear conveying track. The bag pushing component is fixed above the bag conveying track and pushes multiple spout bags located on the bag conveying track in close arrangement sequentially into the linear conveying track inlet.

[0016] Furthermore, the bag-pushing component includes a third slide rail, a third slider, and a spout pusher plate. One end of the spout pusher plate is rotatably connected to the third slider, and the other end can push the spout bag to move.

[0017] Furthermore, the equally spaced bag-separating mechanism includes a bag-separating component located above the linear conveying track and a lifting drive component that controls the overall height of the bag-separating component; the bag-separating component unfolds multiple closely arranged spout bags at equal intervals on the linear conveying track.

[0018] Furthermore, the bag-separating component includes a fourth drive motor, a fourth slide rail, and multiple fourth sliders, each of which is fixed with a guide shaft; the guide shaft can be inserted into the spout of the spout bag and drive the spout bag to move; the fourth drive motor drives the multiple fourth sliders to extend and retract at equal intervals on the fourth slide rail; the fourth slide rail is parallel to the linear conveying track.

[0019] By adopting the above technical solution, this utility model has the following beneficial effects:

[0020] (1) This utility model features a linear layout. The spout bags are arranged in a straight line from the bag conveying mechanism to each functional station. There is no change in the direction of the spout, which avoids the probability of handover and bag jamming. The equipment debugging work is simpler, and it can run smoothly in actual production. Compared with other equipment, it is both stable and efficient. The linear layout, compared with the rotary structure, allows for greater room for functional expansion when customized for customers.

[0021] (2) The linearly distributed card bag moving plate of this utility model is designed with multiple card bag openings, which can cooperate with the spout of the spout bag to transfer the spout bags in batches at equal intervals along a straight line.

[0022] (3) This utility model can simultaneously fill and cap multiple spout bags. Compared with the traditional rotary structure, which can only fill or cap one by one, the efficiency is greatly improved. The equal spacing also enables the spout bags to be accurately connected with the filling station and the capping station.

[0023] (4) The driving mechanism of the card bag moving plate of this utility model can realize the card bag moving plate to move back and forth along the straight conveying track and convey it forward in batches.

[0024] (5) This utility model has a telescopic drive mechanism, which can move the card bag moving plate backward, detach it from the spout bag and return it, which can greatly shorten the distance of the first slide rail, save design costs, and realize multi-batch progressive transmission, thereby improving transmission efficiency and production efficiency.

[0025] (6) This utility model can realize reciprocating linear movement and linear extension through a rotatable connecting rod. It is simple and efficient, with high precision in reciprocating movement. It can effectively connect to the spout bag during the reciprocating extension process.

[0026] (7) The spout of the spout bag of this utility model is stuck in the guide plate of the bag guide mechanism. Under the limiting action of the bag guide plate, each spout bag is arranged in a straight direction in sequence. Under the action of the bag pushing component, the spout bags are pushed into the inlet of the straight conveying track in a tight arrangement.

[0027] (8) The spout push plate of this utility model is rotatably mounted on the third slider. When the spout push plate returns, it can be flipped upward to avoid accidentally pushing the spout bag back.

[0028] (9) This utility model can ensure the precise docking of the spout bags continuously fed by the bag conveying component with the bag by positioning and grouping them at equal intervals, so as to ensure that the subsequent filling and capping station can proceed smoothly.

[0029] (10) The bag-separating component of this utility model will drive the spout bags that are close together to be separated one by one by a certain distance, with the distance between them being consistent. Until the set fixed distance is reached, the drive motor of the bag-separating mechanism stops running, and the lifting drive component drives the bag-separating component to rise as a whole, and the guide shaft disengages from the spout of the spout bag.

The connecting rod 22-4 is rotatably connected to the first slider 22-3 and the bag-carrying moving plate 21, respectively.

[0051] See Figure 3 The bag conveying mechanism 3 includes a bag clamping guide plate 31 and a bag pushing component 32. The bag clamping guide plate 31 is open at one end and connected to the bag conveying track 31-1 at the other end. The bag pushing component 32 is fixed above the bag conveying track 31-1 and pushes multiple spout bags located on the bag conveying track 31-1 in a tightly arranged manner into the inlet of the straight conveying track 1. The spouts are clamped in the guide plate of the bag clamping guide mechanism, and each spout bag is arranged sequentially in one direction according to the guide direction under the limiting action of the bag clamping guide plate. Under the action of the bag pushing component, the spout bags are pushed into the inlet of the straight conveying track in a tightly arranged manner.

[0052] The bag-pushing component 32 includes a third slide rail 32-1, a third slider 32-2, and a spout pusher plate 32-3. One end of the spout pusher plate 32-3 is rotatably connected to the third slider 32-2, and the other end can push the spout bag to move. The spout pusher plate is rotatably mounted on the third slider and can flip upwards when the spout pusher plate returns to prevent the spout bag from being accidentally pushed back.

[0053] See Figure 4 The equally spaced bag-separating mechanism 4 includes a bag-separating component 41 located above the linear conveyor track 1 and a lifting drive component 42 that controls the overall height of the bag-separating component 41. The bag-separating component 41 unfolds multiple closely arranged spout bags at equal intervals on the linear conveyor track 1. The bag-separating component 41 includes a fourth drive motor 41-1, a fourth slide rail 41-2, and multiple fourth sliders 41-3. Each of the multiple fourth sliders 41-3 is fixed with a guide shaft 41-4. The guide shaft 41-4 can be inserted into the spout of the spout bag and drive the spout bag to move. The fourth drive motor 41-1 drives the multiple fourth sliders 41-3 to extend and retract at equal intervals on the fourth slide rail 41-2. The fourth slide rail 41-2 is parallel to the linear conveyor track 1. The equally spaced bag-separating mechanism 4 groups the spout bags continuously fed in by the bag-feeding component 3 at equal intervals through positioning, ensuring precise docking with the bag-transferring mechanism and ensuring smooth operation of subsequent filling and capping stations.

[0054] See Figure 1 The filling mechanism 5 includes multiple filling stations 51 that are equally spaced along the linear conveying track 1; the capping mechanism 7 includes multiple capping stations 71 that are equally spaced along the linear conveying track 1; the spacing between the multiple filling stations 51, the spacing between the multiple capping stations 71, the spacing between the multiple bag openings 21-1 and the spacing between the equal-spacing bag separating mechanism 4 that separates the spout bags are all equal; the number of filling stations 51 and capping stations 71 are equal.

[0055] The bag moving plate 21 drives the equally spaced spout bags to pass through the filling mechanism 5, the cap feeding mechanism 6 and the cap screwing mechanism 7 in batches, completing the filling, cap feeding and cap screwing actions in batches.

[0056] Preferably, the filling station 51 of the filling mechanism 5, the capping station 71 of the capping mechanism 7, and the guide shafts 41-4 of the bag separating component 41 are all configured to be six.

[0057] The filling mechanism 5 in this embodiment is existing equipment, which may include a primary filling and feeding mechanism and a secondary filling and feeding mechanism, with each feeding mechanism having six feeding nozzles.

[0058] In this embodiment, the cap feeding mechanism 6 is an existing device, including a vibrating cap sorter, a cap conveying track, and a cap dropping component. The vibrating cap sorter sorts out a batch of caps and feeds them into the cap conveying track in a consistent direction. The caps pass through the cap conveying track and are delivered to the cap dropping component. The bag transfer component 2 drives the filled spout bags to pass through the cap dropping component station one by one. The caps on the cap dropping component are placed on the spout bags, completing the capping action.

[0059] The capping mechanism 7 in this embodiment is an existing device, equipped with six liftable capping heads.

[0060] The device workflow in this embodiment is as follows:

[0061] (1) Manually hang the spout bag into the bag guide plate 31 of the bag conveying mechanism 3; the bag pushing component 32 moves back and forth to push the spout bags tightly into the entrance of the linear conveying track in sequence;

[0062] (2) The spout bag is pushed into the equidistant bag separating component 4. The design is set so that six spout bags are pushed into the designated work position and are detected by photoelectric detection. The lifting drive component 42 drives the bag separating component 41 to descend as a whole. The six guide shafts are inserted into the mouths of the six closely arranged spout bags in the retracted state. Driven by the fourth drive motor of the bag separating component 41, the six closely arranged spout bags are driven to separate one by one to the set fixed distance. The fourth drive motor stops running, the lifting drive component 42 drives the bag separating component 41 to rise as a whole, and the six guide shafts disengage from the spouts of the spout bags.

[0063] (3) The latch on the moving plate 21 of the bag clamps the edge of the spout of the spout bag, thereby driving a group of six spout bags to enter the next operating station respectively;

[0064] (4) The bag transfer mechanism 2 moves back and forth, and the batches are transferred sequentially until the filling, capping and capping are completed, and then the bag is transferred out of the production line.

[0065] In this embodiment, a linearly distributed bag-carrying moving plate with multiple bag-carrying openings is designed to cooperate with the spouts of the spout bags, allowing for the batch transfer of spout bags along a straight line at equal intervals. A telescopic drive mechanism is designed to move the bag-carrying moving plate backward, detaching it from the spout bags and returning it to its original position. This significantly shortens the distance of the first slide rail, saving design costs and enabling multi-batch progressive transfer, improving transmission and production efficiency. A rotatable connecting rod enables reciprocating linear movement and linear telescopic movement, which is simple, efficient, and provides high precision in reciprocating movement, effectively engaging the spout bags during telescopic movement. This equipment features a linear layout; the spout bags are arranged in a straight line from the bag conveying mechanism to each functional station. There is no change in the direction of the spouts, thus avoiding the probability of handover and bag jamming. Equipment debugging is simpler, and it operates smoothly in actual production, greatly improving production efficiency.

It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
