A continuous bag vending machine

Abstract

This invention relates to the field of bag conveying technology, and more particularly to a continuous bag vending machine. The continuous bag vending machine, due to its internal storage space for storing folded bags, increases the machine's bag capacity. Furthermore, the number of continuously folded bags is 3 to 5 times that of roll-type continuous bags, thereby reducing the frequency of manual bag filling. Simultaneously, because the bag joints do not need to withstand the force of overcoming their own weight during the unwinding and rotation of the bag roll during output, the connection force can be appropriately reduced, facilitating bag removal and tearing, and improving the reliability of bag dispensing.

Description

Technical Field

[0001] This invention relates to the field of bag conveying technology, and more particularly to a continuous bag vending machine. Background Technology

[0002] Most existing bag vending machines use roll-type continuous roll bags, which consists of continuous roll bags wound onto an empty roll with a certain diameter, and the continuous roll bags have discontinuous joints to facilitate selling bags by the number of bags. The bag capacity of the roll-type continuous roll bags is directly reflected in the radial distance of the continuous roll bags, and further reflected in the increased roll diameter when wound onto the empty roll, which is the maximum roll diameter. Therefore, the maximum roll diameter is limited by the space available for its placement, resulting in a small bag capacity per cycle.

[0003] Furthermore, the strength at the joint between the roll-type continuous bags in the bag vending machine is limited by the quality of the bag roll sleeve and the deformation limit of the bag. If the joint force between the bags is too large, it will be difficult to tear, which will lead to the bag being deformed or damaged. If the joint force between the bags is too small, the bag will break off from the joint during the unrolling process. The joint will not be outside the box, which will prevent the next bag from being delivered smoothly.

[0004] Therefore, there is an urgent need for a bag vending machine with large capacity and high bag dispensing reliability. Summary of the Invention

[0040] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 1-3 As shown, this embodiment of the invention provides a continuous bag vending machine including a main body 1, a display unit 2, a control unit 3, a guide unit 4, and a mechanism 5. The display unit 2 is disposed on the main body 1, while the control unit 3, guide unit 4, and mechanism 5 are all disposed within the main body 1. The display unit 2 and mechanism 5 are electrically connected to the control unit 3. The main body 1 has a bag-containing space for storing continuously folded bags 9 formed by sequentially folded bags. One end of the continuously folded bags 9 enters the input end of the mechanism 5 through the guide unit 4. The mechanism 5 transports the bags and outputs them from its output end into the bag outlet slot 111 of the main body 1. In practical applications, after receiving user input information, the display unit 2 sends the input information to the control unit 3 connected to the display unit 2. The control unit 3 controls the mechanism 5 to operate according to the input information. The input information is the quantity of bags the user wishes to purchase.

[0042] The control unit 3 provides working power and working signals to the mechanism 5. The mechanism 5 feeds back the real-time signal of the bag to the control unit 3. The control unit 3 is equipped with a backlight panel, which is connected to the display unit 2 and can control the brightness of the display unit 2 and provide screen content to the display module through the backlight panel. The power of the display unit 2 is provided by the control unit 3.

[0043] Of course, the continuous bag vending machine can also include a human-machine interaction unit 8. The human-machine interaction unit 8 includes a camera 81 and a scanning dock 82 mounted on the main body 1. Both the camera 81 and the scanning dock 82 are electrically connected to the control unit 3. The camera 81 can be used for facial recognition. After receiving the signal, the control unit 3 can control the mechanism 5 to operate and thus dispense the bag. Furthermore, it can facilitate remote video communication with customer service to resolve any issues. The scanning dock 82 is mainly used in hospital settings such as for CT scan bags. The device is connected to the hospital's intranet, and users can scan the CT scan barcode or QR code issued by the hospital. After receiving the signal, the control unit 3 can control the mechanism 5 to operate and thus dispense the bag.

[0044] The continuous bag vending machine of this embodiment has an internal storage space for folded bags, which increases the machine's bag capacity. Furthermore, the number of continuous folded bags 9 is 3 to 5 times that of roll-type continuous bags, thus reducing the frequency of manual bag filling. Additionally, since the continuous folded bags 9 do not need to withstand the force of their own weight at the bag joints during the unwinding and rotation process, the joint force can be appropriately reduced, facilitating bag removal and tearing, and improving the reliability of bag dispensing.

[0045] like Figure 2 As shown, the main body 1 includes a cover 11 and a housing 12, which together form a space for accommodating the control unit 3, the guide unit 4, and the mechanism 5. The cover 11 and the housing 12 are arranged opposite each other in the vertical direction, with one side of the cover 11 hinged to one side of the housing 12. The display unit 2 is disposed on the cover 11, and a bag outlet groove 111 is provided on the cover 11. The mechanism 5 is laterally connected to the housing 12, with its input end located at the top and its output end located at the bottom and corresponding to the bag outlet groove 111. A guide plate 13 is provided between the bag outlet groove 111 and the outlet end of the mechanism 5 to facilitate the bag being output from the outlet of the mechanism 5 to the bag outlet groove 111. The control unit 3 is disposed on the side wall of the cover 11, and the two ends of the guide unit 4 are respectively connected to the opposite side walls of the housing 12.

[0046] like Figure 2 As shown, the guide unit 4 includes a roller 41 and a connecting shaft 42. The roller 41 is sleeved on the connecting shaft 42 and rotatably connected to the connecting shaft 42. The two ends of the connecting shaft 42 are respectively connected to the opposite side walls of the housing 12. The top surface of the roller 41 is higher than the input end of the mechanism 5. In practical applications, the continuous bag vending machine also includes a bag sweeping unit 6. The bag sweeping unit 6 includes a brush 61 and a mounting base 62. The brush 61 is connected to the cover 11 through the mounting base 62. The brush 61 abuts against the roller 41 and can brush away bags that are stuck together, so that the bags can pass evenly through the roller 41 to the mechanism 5.

[0047] like Figure 3 As shown, the continuous bag vending machine also includes a limiting side plate 7, which is disposed inside the housing 12 and detachably connected to the housing 12. The limiting side plate 7, together with the side wall and bottom wall of the housing 12, forms a bag-containing space. A groove is machined on the limiting side plate 7, and a hook is welded to the housing 12. The limiting side plate 7 is fixed to the hook of the housing 12 through the groove. A continuous folding bag 9 is placed in the bag-containing space, and at least three sides of the bag stack of the continuous folding bag 9 are basically in contact with three sides of the bag-containing space. The bottom wall of the housing 12 is provided with a drag plate, and three recesses 121 are formed on the drag plate. The three recesses 121 are arranged at equal intervals. The bottom of the bag stack is placed on the drag plate to facilitate the removal of the strapping of the continuous folding bag stack of the continuous folding bag 9.

[0048] like Figure 4 As shown, the mechanism 5 includes a mounting frame 51, a pressure knife assembly 52, and a roller assembly 53. The mounting frame 51 is laterally connected to the housing 12. The roller assembly 53 includes an active roller 531 and a passive roller 532 disposed within the mounting frame 51. The active roller 531 drives the passive roller 532 to rotate to convey the bag between the active roller 531 and the passive roller 532. Both the active roller 531 and the passive roller 532 are cylindrical structures, meaning that the roller surfaces of the active roller 531 and the passive roller 532 are integral structures without segmentation. As shown, the pressure knife assembly 52 includes an active roller pressure knife unit 521 and a passive roller pressure knife unit 522. The active roller pressure knife unit 521 and the passive roller pressure knife unit 522 are arranged vertically opposite each other and installed at the output end of the mounting frame 51. The blade of the active roller pressure knife unit 521 abuts against the roller surface of the active roller 531, and the blade of the passive roller pressure knife unit 522 abuts against the roller surface of the passive roller 532.

[0049] The input end of the mounting frame 51 is the input end of the mechanism 5, and the output end of the mounting frame 51 is the output end of the mechanism 5. To facilitate the accurate entry of the bag from the roller 41 into the input end of the mounting frame 51, a guide plate 58 is also provided on the mounting frame 51. The bag enters the mounting frame 51 through the guide plate 58.

[0050] like Figure 4 and Figure 7 As shown, since the core mechanism 5 is equipped with a pressure knife assembly 52, after the bag enters from the input end of the mounting frame 51, it passes between the active roller 531 and the passive roller 532. Since the active roller pressure knife unit 521 abuts against the active roller 531 and the passive roller pressure knife unit 522 abuts against the passive roller 532, even if the bag and the active roller 531 or the passive roller 532 in the roller assembly 53 stick together, the pressure knife assembly 52 can scrape the bag off, thereby avoiding the phenomenon of bag roll-up. At the same time, since both the active roller 531 and the passive roller 532 are straight cylindrical structures, the phenomenon of bag clamping in the existing segmented rollers is avoided, increasing the redundancy of the equipment for bags.

[0051] like Figure 4 As shown, the movement mechanism 5 includes a drive unit 57, which includes a power motor 571, a drive gear 572, and a driven gear 573. The drive gear 572 is fixedly connected to the output end of the power motor 571, and the driven gear 573 is fixed to the end of the drive roller 531. The drive gear 572 meshes with the driven gear 573, and the power motor 571 drives the drive gear 572 to rotate so as to drive the driven gear 573 to rotate.

[0052] As shown in Figure 8, the mounting frame 51 includes a base plate 511, a first side plate 512, and a cover plate 513. The first side plate 512 is disposed on both sides of the base plate 511, and the cover plate 513 is disposed on the top of the first side plate 512. The two sides of the cover plate 513 are integrally formed with second side plates 514 perpendicular to the cover plate 513. The base plate 511, the first side plate 512, the second side plate 514, and the cover plate 513 enclose a frame, and the two second side plates 514 in the cover plate 513 are respectively hinged to one side of the two first side plates 512.

[0053] The passive roller pressing unit 522 is disposed between the two second side plates 514, and the active roller pressing unit 521 is disposed between the two first side plates 512. The passive roller pressing unit 522 and the active roller pressing unit 521 are located on the same side. The active roller 531 is disposed between the two first side plates 512 via a bearing seat 574 and is rotatably connected to the first side plate 512. The cover plate 513 is hinged to one side of the first side plate 512, and the cover plate 513 is detachably connected to the other side of the first side plate 512. That is, when the cover plate 513 rotates around one side of the first side plate 512, it can simultaneously drive the passive roller pressing unit 522 and the passive roller 532 on it to separate from the active roller pressing unit 521 and the active roller 531, so as to make the bag flat when changing bags. In this embodiment, the hinge of the cover plate 513 to one side of the first side plate 512 is achieved by a locking pin 515, as shown in the figure, which shows the state when the locking pin 515 is opened.

[0054] like Figure 4 and Figure 8 As shown, the passive roller 532 is disposed between the two second side plates 514 and is rotatably connected to the adjustment component 54 via the adjustment component 54. The adjustment component 54 can drive the passive roller 532 away from or closer to the active roller 531 in the vertical diameter direction, thereby facilitating the adjustment of the roller surface adhesion force between the active roller 531 and the passive roller 532.

[0055] As shown in Figure 8, the active roller pressing unit 521 includes a first pressing blade 5211, a first pressing shaft 5212, a connecting rod 5213, and a plurality of first spring plates 5214. The first pressing blade 5211 is mounted between the first side plates 512 via the first pressing shaft 5212, and the cutting edge of the first pressing blade 5211 abuts against the roller surface of the active roller 531. The plurality of first spring plates 5214 are spaced apart on the connecting rod 5213, and the two ends of the connecting rod 5213 are respectively connected to the two first side plates 512. The abutting part of the first spring plate 5214 abuts against the inner side of the first pressing blade 5211 so that the first pressing blade 5211 is in contact with the roller surface of the active roller 531.

[0056] The passive roller pressing unit 522 includes a second pressing blade 5221, a second pressing shaft 5222, and multiple second spring plates 5223. The second pressing blade 5221 is mounted between the second side plates 514 via the second pressing shaft 5222, and the cutting edge of the second pressing blade 5221 abuts against the roller surface of the passive roller 532. Multiple second spring plates 5223 are spaced apart at the top of the cover plate 513, and the abutting portion of the second spring plates 5223 abuts against the inner side of the second pressing blade 5221 to ensure that the second pressing blade 5221 is in contact with the roller surface of the passive roller 532. In other words, adjusting spring plates are provided to adjust the contact force between the pressing blade and the roller surface by changing the position of the spring plates.

[0057] As shown in Figure 8, the adjustment assembly 54 includes an adjustment fixing plate 541, an adjustment L-plate 542, and a tightening unit 543. The passive roller 532 is rotatably connected to the adjustment L-plate 542 on both sides. The adjustment fixing plate 541 is mounted on the cover plate 513 and extends horizontally beyond the cover plate 513. The tightening unit 543 includes a nut 5431 fixed to the top plate of the adjustment L-plate 542 and a tensioning screw 5432 threadedly connected to the nut 5431. The top of the tensioning screw 5432 extends beyond the nut 5431 and abuts against the adjustment fixing plate 541. By adjusting the tightening force between the tensioning screw 5432 and the adjustment fixing plate 541, the tensioning screw 5432 drives the adjustment L-plate 542 to move up and down, thereby causing the roller surface of the passive roller 532 on the adjustment L-plate 542 to move closer to or further away from the active roller 531, adjusting the adhesion force between the two roller surfaces and preventing the bag from deviating during transport.

[0058] The mechanism 5 also includes a locking assembly 55, which includes a buckle 551 disposed on the second side plate 514 and a hook 552 disposed on the first side plate 512. When the mechanism 5 is in operation, the buckle 551 and the hook 552 engage, thereby fastening the second side plate 514 and the first side plate 512 on the cover plate 513. Since the active roller 531 is covered with a non-metallic material and the passive roller 532 is a steel roller, the static electricity generated by the friction between the bag and the roller surface can be discharged through the passive roller 532.

[0059] The mechanism 5 also includes a sensing component 56 electrically connected to the control unit 3. The sensing component 56 includes a signal line interface terminal 561 and a sensor 562. The signal line interface terminal 561 and the sensor 562 are connected to the outlet end of the mounting bracket 51 through an arc plate 563.

[0060] When the mechanism 5 is working, the second side plate 514 on the cover plate 513 is in a closed state with the first side plate 512. The buckle 551 and the hook 552 are locked together. The signal line interface terminal 561 is connected to the control unit 3 and can receive commands. The active roller 531 and the passive roller 532 are in contact to clamp and send the bag out. The sensor 562 senses the bag and provides feedback on the bag's exit status.

[0061] A power adapter is also provided on the main body 1. After the power adapter is connected to the power source, the entire device is powered on and starts up. The sensor 562 and control unit 3 of the core mechanism 5 are both powered by the power adapter. The control unit 3 integrates a communication module and an Android board module. The communication module enables the control unit 3 to remotely interact with the R&D center and complete real-time data transmission and system upgrades.
