Description

Floating mechanism and money detector of money detector

[0001] The present invention belongs to the technical field of financial equipment, and particularly relates to a floating mechanism and a money detector of a money detector.

[0002] In the existing financial cycle machine, there is a banknote verification module, and the banknote detection module has a banknote passage, and a roller wheel is arranged above and below the banknote passage, so as to avoid banknote abrasion and banknote, one of the rollers Need to be mounted on a floating shaft. There are discretely arranged detection points between the rollers. When the banknotes are pushed by the rollers and passed through the distributed detection points, each of the detection points detects the designated position of the banknotes to determine whether it is a counterfeit banknote. When the banknotes have a deviation in the position of the channel, the accuracy of the detection will be affected. In addition, installation and maintenance are difficult due to the large number of inspection points and the need to install different locations.

[0003] The floating structure of the floating detector of the existing money detector module is realized by a pair of torsion springs to ensure that the floating shaft slides up and down in the design track groove; under normal circumstances, the bending arms of the left and right torsion springs act on the rib bearing Outside, during the actual working process of the money detector module, that is, the bending arm of the torsion spring on both sides of the floating shaft may have a position away from the bearing of the rib bearing, that is to say, the floating spring effect of the torsion spring structure has a potential risk, resulting in a potential risk When the banknotes enter and leave the magnetic mechanism, the magnetic mechanism cannot accurately collect the magnetic information of the banknotes, and the banknotes may also cause the banknotes to be banknotes at the position of the magnetic mechanism, thereby causing equipment failure;

[0004] The contact between the torsion spring and the rib bearing is point contact, and the design of the bending arm is limited by the position of the rib bearing rib, so it should not be too long, and the bending end of the same torsion spring is not well controlled. The components will be different from each other, which is reflected on the outer side of the rib bearing on both sides of the floating shaft. The force points on the left and right sides of the floating shaft are inconsistent due to different force points, and the position of the torsion spring can not be adjusted;

[0005] In addition, the torsion spring is easily deformed due to the wire diameter (generally designed to be 0.8-lmm), which is also a problem in the logistics process, so that the force of the torsion spring assembled on the left and right sides acts on the rib bearing, The torsion spring processing technology must be strictly controlled, which will increase the cost of individual components;

[0006] The torsion spring is a symmetrical structure, that is, the left and right torsion springs are two parts, which cannot be replaced, and need to manage two parts, resulting in an increase in processing cost and maintenance cost.

Embodiments of the invention

[0041] In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the application and are not intended to be limiting.

[0042] It should be noted that when an element is referred to as being "fixed" or "in" another element, the element can be directly on the other element or possibly the same. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or.

[0043] As shown in FIG. 1 , the floating mechanism of the money detector of the present invention includes a bracket 1 and a floating shaft 3 that can float up and down with respect to the bracket 1 , and two elastic pieces 2 are also provided, and the floating shaft is provided. Each of the left and right ends of the sleeve 3 is provided with a rib bearing 4, and the bracket 1 includes two support plates 11 parallel to each other and a fixing plate 12 disposed between the two support plates 11, and the left end of the floating shaft 3 passes through the corresponding block The side bearing 4 is mounted on a support plate 11 , and the right end is mounted on the other support plate 11 via a corresponding rib bearing 4 . One end of each elastic piece 2 is fixed on the fixed plate 12 , and the other end abuts against the corresponding rib bearing 4 is close to the side of the fixed plate 12, so that the floating shaft 3 floats in a direction perpendicular to the transport direction of the banknote (ie, the floating shaft 3 floats up and down), so that the side bearing 4 is close to the side of the fixed plate 12, that is, the fixed plate 12 on the radially outer edge of the opposite rim bearing 4.

[0044] The floating shaft 3 is supported by the two supporting plates 11 which are parallel to each other, and the floating shaft 3 is floated up and down by the one end of the fixing plate 12, and the two elastic pieces 2 act on the action point of the corresponding rib bearing 4. On the side of the rib bearing 4 close to the fixing plate 12, the elastic force of the left and right elastic pieces 2 acting on the left and right rib bearing 4 is ensured, thereby ensuring the normal and stable operation of the floating shaft 3, thereby ensuring reliable collection of the money detector. The magnetic information of the banknote, especially when the banknote enters or leaves the floating mechanism, the floating mechanism can work normally; since the elastic piece 2 does not deform in a plane parallel to the axial direction of the floating shaft 3, it is more beneficial to ensure the left and right The elastic force of the elastic piece 2 acting on the left and right rib bearing 4 is uniform, that is, the consistency of the force of the floating shaft 3 is further improved, and the floating shaft 3 has better working stability. The left and right elastic pieces 2 can adopt the same structure (as shown in Fig. 2), and there is no need to distinguish between the processes. Only one part needs to be managed in the component management, which reduces the processing cost and maintenance cost of the parts.

Further, in the embodiment of the present application, the fixing position of the elastic piece 2 on the fixing plate 12 is adjustable in the left-right direction. It is beneficial to ensure that the elastic force of the left and right ends of the elastic piece 2 acting on the left and right ends of the floating shaft 3 is consistent, in particular, the processing cost of the parts of the elastic piece 2 is reduced, because the bending angle of the processing of the elastic piece 2 has a certain tolerance, so In the same installation position, the force of the different elastic pieces 2 acting on the extension of the corresponding rib bearing 4 is inconsistent, and the installation position of the elastic piece 2 is designed to be an adjustable mode, thereby compensating for the machining deviation of the parts and avoiding the action of the elastic piece 2 due to the machining deviation. The elastic force of the floating shafts 3 on both sides is inconsistent, which reduces the control of the processing precision of the shrapnel 2 and reduces the processing cost. If the processing deviation of the elastic piece 2 occurs, and the deviation is not compensated, the following problem occurs: In the rational state, the banknote is rushed between the magnetic sensor 5 and the floating roller 6 provided on the floating shaft 3, The force of the banknote medium on the floating roller 6 at both ends of the floating shaft 3 and the reaction force of the floating roller 6 at the two ends of the floating shaft 3 on the banknote are different, and then the medium is inclined from the floating roller 6吋, and the tilting is severe, and the banknote cannot be caused. Lifting the floating shaft 3 causes the problem of banknotes; if the processing precision of the shrapnel 2 is increased, the processing technology of the shrapnel 2 needs to be strictly controlled, not only the processing efficiency is lowered, but also the yield rate is lowered, which inevitably causes the cost of the shrapnel 2 to be high; The arrangement of the elastic piece 2 in the left-right direction of the fixing plate 12 is adjustable, which is advantageous for reducing the cost of the elastic piece 2 and ensuring normal and stable operation of the floating shaft 3.

[0046] Specifically, the fixing position of the elastic piece 2 on the fixing plate 12 can be adjusted in the left-right direction by adopting the following structure: the elastic piece 2 and the fixing plate 12 are slidably engaged, and the fixing plate 12 is provided with a locking member, and the locking device is locked.吋 The positioning of the elastic piece 2 and the fixing plate 12 is realized, and the lock is unlocked, and the positions of the elastic piece 2 and the fixed plate 12 are adjusted. Of course, the fixed position of the elastic piece 2 on the fixing plate 12 can be adjusted in the left-right direction by using the following structure: a spring mounting portion is disposed at both ends of the fixing plate 12, and each elastic piece mounting portion is arranged at intervals in the left-right direction. A plurality of sets of elastic fixing positions (each of the elastic fixing positions may include one elastic fixing position, and may also include a plurality of elastic fixing positions), and the elastic piece 2 is selectively detachably fixed to a set of elastic fixing positions, that is, according to It is necessary to fix the elastic piece 2 to any one of the elastic pieces of the elastic piece mounting portion corresponding to the elastic piece 2.

[0047] Further, in the embodiment of the present application, the fixed position of each elastic piece 2 on the fixing plate 12 is adjustable in the left-right direction to a range of 2-3 mm. That is, the principle of the left and right adjustment of the position of the elastic piece 2 on the fixed plate 12 is floating. The left and right axes 3 allow the elastic piece 2 to move within a range of 2-3 mm, so as to ensure that the end of the elastic piece 2 cannot be separated from the radial outer edge of the rib bearing 4, thereby ensuring that the floating shaft 3 is stably floated in the vertical direction, and the inspection is performed. The banknote device reliably collects data information.

[0048] Further, as shown in FIG. 3, in the embodiment of the present application, the elastic plate 2 is provided with a first adjusting hole 21, and the fixing plate 12 is provided with a first fixing hole 121, of course, the first adjusting hole 21 and the first The position of a fixing hole 121 is also interchangeable, that is, the elastic piece 2 is provided with a first fixing hole 121, and the fixing plate 12 is provided with a first adjusting hole 21; the elastic piece 2 and the fixing plate 12 can pass only the first screw For example, the first screw passes through the first adjusting hole 21 and is screwed to the first fixing hole 121. Of course, the elastic piece 2 and the fixing plate 12 can also be fixed by the first screw, for example, the first screw runs through. The first adjusting hole 21 and the first fixing hole 121 are screwed to the first nut, or the first screw is threaded through the first fixing hole 121 and the first adjusting hole 21 and then screwed to the first nut; the first adjusting hole The length of 21 is larger than the outer diameter of the first screw, and the longitudinal direction of the first adjustment hole 21 coincides with the axial direction of the floating shaft 3. The first screw functions to fix the elastic piece 2 and the fixing plate 12 on the one hand, and also guides the left and right movement of the elastic piece 2 relative to the fixed plate 12 on the other hand, and needs to adjust the installation of the elastic piece 2 in the left-right direction of the fixed plate 12. Position 吋, just loosen the first screw and move the first screw relative to the first adjusting hole 21, then the adjusting elastic piece 2 can be slid to the required mounting position, and then the first screw can be tightened, the structure is simple and easy Adjusting the position of the elastic piece 2 in the left and right direction is easy to operate.

The elastic piece 2 includes three portions of a head portion 22, a middle portion 23 and a tail portion 24, and the head portion 22 is parallel to the fixing plate 12, which is advantageous for fixing the elastic piece 2 to the fixing plate 12 stably and reliably, and bending the tail portion 24 with respect to the fixing plate 12. The angle is greater than the bending angle of the middle portion 23 relative to the fixed plate 12, On the one hand, it can reduce the elastic force of the elastic plate 2 deformation fixing plate 12, and on the other hand, it can increase the reliable contact between the rib bearing 4 and the elastic piece 2, greatly increasing the stability of the structure and ensuring the elastic force at both ends of the floating shaft 3. Consistently, the floating roller 6 on the banknote detecting floating shaft 3 is fully pressed against the banknotes, so that the magnetic sensor 5 of the money detector device collects the information of the banknotes, and the banknotes are smoothly carried out smoothly.
