[0035] The technical content of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] <First Embodiment>

[0037] See also Figure 2-3As shown, an embodiment of the present invention provides a securities sorting device 100 for sorting securities, comprising a stacking process mechanism 1, a sorting and lifting mechanism 2, and a bundling process mechanism 3 arranged in sequence according to the production process. The stacking process mechanism 1 is used to stack a number of bales specified by the production process and then send them to the sorting and lifting mechanism 2, the sorting and lifting mechanism 2 is used to lift the bales and simultaneously complete the sorting and centering, and the bundling process mechanism 3 is used to bundle the sorted bales;

[0038] Among them, the sorting and lifting mechanism 2 includes: a frame 21; a product pallet 22 arranged above the top plate 211 of the frame 21; a lifting electric cylinder 23 located below the top plate 211 of the frame 21, and the push rod of the lifting electric cylinder 23 passes through the top plate 211 of the frame 21 and is connected to the product pallet 22; a guide shaft assembly 24 arranged between the product pallet 22 and the top plate 211 of the frame 21; a left-side sorting assembly 25 is provided on the left side of the product pallet 22, and the left-side sorting assembly 25 is connected to the left side of the frame 21 via a left-side roller guide assembly 26; a right-side sorting assembly 27 is provided on the right side of the product pallet 22, and the right-side sorting assembly 27 is connected to the right side of the frame 21 via a right-side roller guide assembly 28. The left-side sorting assembly 25 and the right-side sorting assembly 27 and the left-side roller guide assembly 26 and the right-side roller guide assembly 28 symmetrically arranged on both sides of the sorting and lifting mechanism 2 are used to complete the centering and aligning actions of the bags.

[0039] It should be noted that, in the embodiment of the present invention, the stacking process is the preceding process, the sorting and lifting process is the middle process, and the bundling process is the following process. Figure 1 The layout is arranged in the front direction A (i.e., the front and rear direction) as shown in the figure. The working process is that the push rod of the previous process pushes the Baibao product onto the product pallet of the sorting and lifting mechanism. When the push rod is withdrawn to the initial position, the lifting cylinder starts to lift. In the process of lifting the product from the first position (initial position) to the second position (final position), the left sorting component and the left roller guide component, the right sorting component and the right roller guide component cooperate to complete the sorting action of aligning and centering the product according to the preset trajectory. When the product is about to reach the second position, the left and right sorting components retreat from the product to prepare for the subsequent process. The entire sorting action does not occupy the process time alone, and the production efficiency is high.

[0040] In addition, in the embodiment of the present invention, Figure 3 The B direction (i.e., left and right direction) is the left roller guide assembly, the left sorting assembly, the product pallet, the right sorting assembly, and the right roller guide assembly. The sorting and lifting mechanism in the embodiment of the present invention has a simple structure, few drive units, simple control, reliable operation, and low cost.

[0041] Alternatively, see Figure 4As shown, the left-side sorting assembly 25 in the sorting device 100 in the embodiment of the present invention includes: a base 251, a slide bar 252 arranged on the base 251, a sorting rod 253 is arranged at the first end of the slide bar 252, the sorting rod 253 is connected to the slide bar 252 through a sorting rod mounting plate 254, a cam roller 255 capable of maintaining continuous contact with the left-side roller guide assembly 26 is arranged on the side of the first end of the slide bar 252, a buffer spring 256 is arranged on the sorting rod mounting plate 254, and a first rear support 25 is arranged above the second end of the slide bar 252. 71. A second rear support 2572 is provided above the base 251. The first rear support 2571 and the second rear support 2572 as well as the second rear support 2572 and the sorting rod mounting plate 254 are connected via a spring slide bar 258. A compression return spring 2591 is provided on the spring slide bar 258 between the first rear support 2571 and the second rear support 2572. Spring supports 2573 are provided above the first rear support 2571 and the second rear support 2572. The two spring supports 2573 are connected via a tension return spring 2592.

[0042] It should be noted that the tidying rod in the embodiment of the present invention includes two tidying parts. In addition, the side of the slide bar in the embodiment of the present invention is provided with one or two grease storage grooves.

[0043] In the embodiment of the present invention, the base is used to support the entire sorting assembly and keep the sorting assembly in the correct position; the slide rod drives the sorting rod installed at the front end to move left and right in the horizontal direction to complete the functions of aligning and centering the products; the cam roller is combined with the working surface a (see Figure 5 As shown in the figure, the upper working position always maintains continuous contact (except the initial position and the upper working position) and maintains appropriate contact force, so that the movement trajectory of the sorting rod connected thereto meets the design requirements and achieves the purpose of sorting the products.

[0044] The working surface a contains at least two depressions and one protrusion between the depressions. When the cam roller moves to the depression position, under the combined action of the spring, the slide bar moves to the left, driving the sorting bar to move to the left and away from the product; when the cam roller moves to the protrusion, under the combined action of the spring, the slide bar moves to the right, driving the sorting bar to move to the right to squeeze the product, so that the positions of all products tend to be consistent in the horizontal direction, achieving the purpose of aligning and centering the product. In this way, the product can be sorted three times using one protrusion and two depressions on the working surface a and the curved surfaces of the initial and final sections of the working surface a. N (N>=1) protrusions can be set according to the product status and production needs. The value of N is determined by the distance the product is lifted and the size of the structure such as the cam roller. The travel between the depression and the protrusion can be determined by factors such as the slope of the rising and falling of the depression curved surface, the depth of the depression, the distance the product is lifted, and the production process requirements.

[0045] Below Figure 5 Take as an example to explain the process and effect of the cam roller working on the working surface a. In the figure, two protrusions and three depressions are taken as an example. The thin solid line on the working surface a is used to mark the virtual boundary line of the curved surface.

[0046] Figure 5 The working surface a in the figure is composed of a1, a2, a3 and a4. The curvature of the a1 part is small and the surface is relatively gentle. When the cam roller moves on the a1 surface from the initial position, it drives the slide rod and the sorting rod to slowly approach the product and squeeze the product. The sorting function of this part of the surface is: to squeeze the irregularly placed package as a whole to the correct position; to slowly squeeze the loose and horizontally irregular single banknotes in the package, so that the position of the product in the package tends to be uniform. The surface a2 shown in the figure contains 1 protrusion and two depressions, and the depressions are divided into the first depression and the second depression in order from bottom to top. The slope of the descending part of the two depressions is small (the descent is relatively gentle), and the slope of the rising part of the two depressions is large (the rise is relatively rapid). The depth of the first depression is greater than that of the second depression, and the rising slope of the first depression is less than that of the second depression. The cam roller moves from surface a1 to curved surface a2. When it enters the descending part of the first depression, it drives the slide bar and the sorting bar to slowly leave and detach from the product. This process can further correct the position of the loose banknotes in the hundred bags; when the roller enters the ascending part of the first depression, it drives the slide bar and the sorting bar to approach the product at a faster speed again, forming a knocking vibration effect on the product, further squeezing the hundred bags and the loose single products in the hundred bags; when it enters the descending part of the second depression, the roller drives the slide bar and the sorting bar to slowly leave and detach from the product again. In this process, the sorting bar further corrects the loose products in the hundred bags, and the distance of the sorting bar detaching is less than the first time it detaches; when it enters the ascending part of the second depression, the cam roller drives the slide bar and the sorting bar to quickly approach the product, further knocking and vibrating the product, squeezing the hundred bags and the loose products in the hundred bags, so that the banknotes in the hundred bags and the hundred bags are further consistent. Curved surface a3 contains a depression, called the third depression. The depth of the third depression is the smallest, and the slopes of the ascending and descending surfaces are relatively small (the ascending and descending are relatively gentle). When the cam roller moves on a3, it is used to correct the skew of the hundred-pack caused by abnormal conditions and further organize the loose banknotes in the hundred-pack. The curved surface of a4 is a plane. When the roller moves on it, it completes the final arrangement and limit of the hundred-pack and is ready to completely separate from the product. At this point, a complete arrangement process is completed. When the cam roller moves on the a surface, the arrangement rod combines fast and slow, squeezes multiple times, and returns to a position closer and closer to the product to complete multiple alignment and centering of the product. It can conveniently arrange the position of the hundred-pack, effectively align the loose single products in the hundred-pack, and achieve high-quality alignment and centering of banknotes.

[0047] It should be noted that a flat surface is allowed to exist on the top of the protrusion between the two recesses.

[0048] When there are multiple protrusions, the top height of each protrusion may gradually increase from bottom to top.

[0049] In particular, the arranging action of the arranging rod in the horizontal direction to approach or separate from the product quickly or slowly can also be formed by the combined effect of the shape of the curved surface a of the roller guide plate and the motor speed curve.

[0050] The tension return spring provides pulling force for the sorting rod when it retracts and resets, and the compression return spring provides thrust for the sorting rod when it resets on the lower side; the buffer spring allows the sorting rod to be slightly adjusted within a certain range, reducing the impact on the product. At the same time, on the premise of ensuring alignment and centering, it can increase the redundancy of the mechanism to accommodate product dimensional deviations and reduce the jamming failure rate caused by factors such as dimensional abnormalities during the sorting process.

[0051] Alternatively, see Figure 4 As shown, the left sorting component 25 in the sorting device 100 in the embodiment of the present invention also includes a product adjustment knob 2541 arranged on the sorting rod mounting plate 254, and the product adjustment knob 2541 is used to adjust the initial position of the sorting rod 253 to adapt to products of different sizes.

[0052] Alternatively, see Figure 4 As shown, the left arranging assembly 25 in the arranging device 100 in the embodiment of the present invention further includes a spring adjustment nut 2581 which is arranged on the spring slide bar 258 and connected to the compression return spring 2591. The spring adjustment nut 2581 is used to adjust the relative force of the tension return spring 2592 and the compression return spring 2591, so that the cam roller is kept at a specific position when it is at the upper and lower limit positions, and during the whole action process, the cam roller maintains an appropriate contact force with the working surface a of the roller guide plate;

[0053] Alternatively, see Figure 5 As shown, the left roller guide assembly 26 in the sorting device 100 in the embodiment of the present invention includes a roller guide plate bracket 261 and a roller guide plate 262 arranged on the roller guide plate bracket 261. The roller guide plate bracket 261 is connected to the left side of the frame 21. When the cam roller 255 moves along the roller guide plate 262, the sorting rod 253 moves in the first direction ( Figure 3 Reciprocating motion is performed in the direction B as shown. Figure 5 The middle working surface a is a curved surface. The curved surface is used to dynamically align and center the product multiple times during the lifting process to improve the finishing effect. Figure 5 The middle arrow indicates the movement direction of the cam roller when the finishing and lifting mechanism is working, wherein the lower side is the initial position of the cam roller, and the upper side is the position of the cam roller when the finishing and lifting module is in the second position (i.e., the upper working position). Figure 6The slide groove of the roller guide plate can be in the form of a closed slide groove. As an alternative, Figure 7 and Figure 8 The roller guide plate shown in the figure can also be used as the slideway Figure 7 The structure shown achieves the purpose of reversing the sorting assembly between the upper station and the lower station. At this time, the sorting lifting mechanism can achieve the purpose of one-way circulation of the cam roller without compressing the return spring.

[0054] Optionally, the sorting device 100 in the embodiment of the present invention further includes two limit position sensors, which are respectively arranged at the upper and lower parts of the lifting cylinder 23, and are used to force shutdown when an abnormal condition occurs in the actual stroke of the lifting cylinder during production.

[0055] Alternatively, see Figure 2 As shown, in the arranging device 100 in the embodiment of the present invention, the bottom of the legs 212 of the frame 21 is provided with adjusting casters 213, and the adjusting casters 213 are used to adjust the position of the arranging lifting mechanism 2 in the vertical direction.

[0056] Optionally, the stacking process mechanism 1 in the sorting device 100 in the embodiment of the present invention includes an outward push cylinder and an outward push rod connected to the outward push cylinder, and the outward push cylinder is provided with a first extending end magnetic sensor and a retracting end magnetic sensor. When the outward push rod is extended to a preset stroke, the extending end magnetic sensor is triggered, and when the outward push rod is retracted to the initial position of the outward push rod, the retracting end magnetic sensor is triggered.

[0057] Optionally, the bundling process mechanism 3 in the sorting device 100 in the embodiment of the present invention includes a feeding cylinder and a feeding assembly connected to the feeding cylinder, and a second extending end magnetic sensor is provided on the feeding cylinder. When the feeding assembly pushes the bales on the product pallet to the preset station of the bundling process, the second extending end magnetic sensor is triggered.

[0058] To sum up, the lifting, sorting and centering actions of the sorting device in the embodiment of the present invention are completed in one process, and the entire mechanism has a compact structure, small footprint, high integration and high efficiency; and only one driving unit is needed to complete the lifting of the product, which is simple to control and low in cost; in addition, the embodiment of the present invention realizes precise centering of the product from the mechanical structure, and the position of the final product is stable and reliable. The sorting rod has a buffer element and has good tolerance for dimensional errors of the product. The sorting rod moves with the product and has no relative movement with the product, so it will not cause damage such as wear to the product, and the product can still be sorted multiple times during the lifting process.

[0059] <Second Embodiment>

[0060] The embodiment of the present invention further provides a control method of a securities arrangement device, which is used for securities arrangement. The method comprises the following steps:

[0061] Step S1: In the initial state, the lifting electric cylinder is in the lower working position specified by the program. When the first extension end magnetic sensor and the retracted end magnetic sensor of the outward push cylinder of the stacking process mechanism are detected to be triggered in sequence, the lifting electric cylinder starts to rise according to the speed curve and trajectory curve set by the program, and drives the left and right sorting components to move synchronously, and cooperates with the left and right roller guide components to realize the alignment and centering of the bags;

[0062] Step S2: When the lifting cylinder rises to the upper working position, the left finishing assembly and the right finishing assembly retreat to the initial position under the action of the tension return spring and the compression return spring. At this time, the left finishing assembly and the right finishing assembly are separated from the bag;

[0063] Step S3: The lifting cylinder continues to move upward to the end position set by the program and then stops.

[0064] Specifically, the lifting electric cylinder pushes the product pallet to move upward, driving the left and right sorting components to move upward, the cam roller contacts the inner working surface of the roller guide plate and rolls along the curved surface, and its horizontal movement drives the sorting rod to move in the horizontal direction. The movement trajectories of the left and right sorting components are symmetrical, so as to realize the alignment and centering of the products. When it reaches the second position (i.e. the upper working position), the cam roller disengages from the roller guide plate and resets to the initial position (i.e. the lower working position) under the action of the tension return spring. At this time, the sorting rod disengages from the product and retreats. After the product is transferred, the lifting electric cylinder starts to descend, and the cam roller contacts the outer working surface of the roller guide plate again and moves along the curved surface. The sorting rod further retreats and descends at the same time. When it descends to the initial position, the cam roller disengages from the working surface of the roller guide plate and resets to the initial position under the action of the compression return spring, waiting for the next working cycle.

[0065] In the embodiment of the present invention, the working process of the sorting and lifting mechanism and the preceding and following processes is as follows: after the stacking process mechanism (i.e., the preceding process) completes the stacking of the specified number of bags of the production process, its push rod (the driving element is the push cylinder) pushes outward, and when the push cylinder extends to the preset stroke (i.e., when the product is pushed to the set position on the product tray in the sorting and lifting mechanism), the extended end magnetic sensor on the push cylinder is triggered, and the push cylinder stops pushing outward and reverses and retracts, and when the push rod retracts to the initial position (reset), the retracted end magnetic sensor on the initial position of the push cylinder is triggered, and the push cylinder stops moving. Then, the stacking process proceeds to the next working cycle, and the sorting and lifting mechanism starts working at the same time. After the lifting electric cylinder of the sorting lifting mechanism reaches the final position, the control program notifies the bundling process mechanism (i.e. the subsequent process) to start the action, and the feeding assembly of the bundling process mechanism (the driving element is the feeding cylinder) begins to extend, pushing the product from the product pallet of the sorting lifting mechanism to the preset position of the bundling process mechanism. At this time, the extending end magnetic sensor on the feeding cylinder of the bundling process mechanism is triggered, and the lifting electric cylinder of the sorting lifting mechanism begins to descend and returns to the initial position to wait for the next working cycle. At the same time, the feeding cylinder retracts to the initial position of the cylinder to wait for the next working cycle.

[0066] In the embodiment of the present invention, the upper and lower working positions (i.e., the initial position and the final lifting position) of the lifting electric cylinder are set by the program and can be flexibly modified according to the actual needs of the previous and next processes. In the process of lifting the product from the first position (initial position) to the second position (final lifting position), the sorting components on the left and right sides complete the sorting actions such as aligning and centering the product. Among them, the speed curve and motion trajectory of the lifting electric cylinder between the initial position and the final lifting position can be adjusted and configured according to production needs, and can be coordinated with the roller guide components on both sides to complete sorting actions of different frequencies and forces and repeated multiple times, so as to facilitate the alignment and centering of products with different face qualities and ensure the neatness and consistency of the produced products.

[0067] In summary, the present invention can realize the alignment and centering of products during the lifting process, does not occupy the process time separately, and has high efficiency; the sorting action is realized in conjunction with the lifting action, with fewer drive units and simple control; multiple dynamic alignment and centering of products can be realized during the lifting process of the products; and a variety of sorting actions of the sorting rod can be realized by designing the working surface of the roller guide plate.

[0068] The above is a detailed description of the securities arrangement device and control method provided by the present invention. For those skilled in the art, any obvious changes made to the present invention without departing from the essence of the present invention will constitute an infringement of the patent right of the present invention and will bear corresponding legal responsibilities.
