Description

Technical Field

[0001] This utility model belongs to the technical field of laser perforation, rewinding, and printing of tipping paper in the tobacco industry, and specifically relates to a clamp for tipping paper trays. Background Technology

[0002] Currently, in the tobacco tipping paper industry, especially in laser perforation equipment, rewinding equipment, and printing equipment, it is necessary to transfer the cake-shaped material from the feeding rack to the unwinding shaft. After the operation is completed, the material tray on the take-up shaft needs to be transferred to the unloading rack. Currently, both of these actions are done manually.

[0003] To address the issues of high labor intensity and frequent operation of existing manual loading and unloading trays, an automated loading and unloading device is adopted to replace manual loading and unloading. However, the existing clamps do not have an ideal clamping effect on the splicing paper trays, and there are problems such as unstable clamping that makes them easy to fall, and excessive clamping force that damages the splicing paper.

Multiple clamping members are distributed in a ring on the carrier plate, so that the multiple clamping arc plates form a circular clamping ring, and some or all of the clamping members are provided on the carrier plate through the drive assembly; the drive assembly drives the clamping members to run radially along the clamping ring to clamp or release the trays.

[0006] Furthermore, the support rod has a hollow structure, and its front end is vertically fixed to the center of the carrier plate. An inlet hole is opened at the center of the carrier plate corresponding to the front end of the support rod. Multiple clamping members are distributed in a ring around the inlet hole.

[0007] Furthermore, an outlet hole is provided on the side wall of the support rod, and the outlet hole and the inlet hole are connected through the hollow inner cavity of the support rod; a sensor for detecting the position of the material tray is provided at the center of the carrier plate, and the sensor is suspended above the inlet hole.

The stop plate is parallel to the carrier plate, and the mounting plate is vertically disposed below the stop plate. The outer edge of the stop plate is arc-shaped, and the clamping arc plate is vertically disposed at the outer edge of the upper side of the stop plate.

[0010] Furthermore, the driving assembly is fixed to the carrier plate radially along the clamping ring, and the telescopic end of the driving assembly faces outward; the telescopic end is fixed to the inner side of the mounting plate, so that the clamping arc plate faces the center of the clamping ring, and the lower end face of the mounting plate just slides in contact with the carrier plate; the driving assembly drives the clamping member to run radially along the clamping ring through the extension and retraction of the telescopic end.

[0011] Furthermore, the clamping member is vertically fixed to the carrier plate via the mounting plate, so that the stop plate is parallel to the carrier plate and the clamping arc plate faces the center of the clamping ring.

[0012] Furthermore, the drive assembly includes multiple parallel telescopic structures and connecting plates. The telescopic strokes of the two telescopic structures are the same, and the telescopic ends of the two telescopic structures are fixedly connected to the connecting plate. The connecting plate is fixedly connected to the mounting plate.

The limiting block is fixed at the front end of the telescopic structure.

[0013] Furthermore, the carrier plate is equipped with two clamping members, both of which are mounted on the carrier plate via the driving assembly.

[0014] Furthermore, the carrier plate is equipped with two clamping members, one of which is mounted on the carrier plate via the drive assembly.

[0015] Furthermore, the two clamping members are symmetrically distributed around the center of the carrier plate, and the maximum distance between the two clamping members exceeds the diameter of the tray.

[0021] To more clearly illustrate the technical solutions in the embodiments of this utility model and the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0022] This utility model embodiment provides a clamp for receiving paper trays. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 It mainly includes a support rod 5, a drive assembly 4, and a clamping member 3 for clamping the material tray 1. The end of the support rod 5 is provided with a carrier plate 51. The clamping member 3 is provided with an arc-shaped clamping arc plate 31. Multiple clamping members 3 are distributed in a ring on the carrier plate 51, so that multiple clamping arc plates 31 form a circular clamping ring. Some or all of the clamping members 3 are provided on the carrier plate 51 through the drive assembly 4. The drive assembly 4 drives the clamping members 3 to run radially along the clamping ring to clamp or release the material tray 1.

[0023] In this application, the support rod 5 serves as the carrier of the clamp. The support rod 5 can be connected to other displacement devices, such as robotic arms or three-dimensional displacement structures. These other displacement devices drive the clamp to grasp, hold, and release the material tray 1, transferring it from its storage position to the feeding position of the punching machine, thus maintaining normal operation of the punching machine. Furthermore, when replacing the material tray 1, it is transferred from the feeding position to the unloading frame or other designated unloading position.

[0024] In the embodiments of this application, the support rod 5 may be a hollow structure with an open front end and a connecting end for connection with other displacement devices. The front end of the support rod 5 is vertically fixed to the center of the carrier plate 51. An inlet hole 52 is opened at the center of the carrier plate 51 corresponding to the front port of the support rod 5. At the same time, an outlet hole is opened on the side wall of the support rod 5. The outlet hole and the inlet hole 52 are connected through the hollow inner cavity of the support rod 5, so that the wire of the drive component 4 mounted on the carrier plate 51 can be introduced into the support rod 5 through the inlet hole 52 and led out from the outlet hole on the side wall, so as not to occupy the clamping operation space on the front side of the carrier plate 51 and to eliminate the interference of the wire to the clamping operation.

[0025] Multiple clamping components 3 are arranged in a ring around the inlet hole 52, so that multiple clamping arc plates 31 form a circular clamping ring, and the material tray 1 is clamped in the clamping ring. Therefore, the maximum diameter of the clamping ring should be greater than the diameter of the material tray 1.

[0026] When multiple clamping components 3 are used to clamp the material tray 1, the multiple clamping components 3 can have two installation forms: one is to be installed based on the drive component 4 to achieve radial operation; the other is to be installed based on its own structure and fixed on the carrier plate 51.

[0027] In a preferred embodiment, all clamping components 3 can be installed based on the drive assembly 4, so that the clamping components 3 can expand and shrink the clamping ring when running radially on the carrier plate 51. When shrinking the clamping ring, the material tray 1 is clamped; when expanding the clamping ring, the material tray 1 is released.

[0028] As a feasible embodiment, some clamping members 3 can be fixedly mounted on the carrier plate 51, and other clamping members 3 can be mounted on the carrier plate 51 based on the drive assembly 4. The two clamping members 3 cooperate to achieve clamping and release. At this time, the clamping ring does not expand and shrink as a whole, but only partially expands and shrinks. Meanwhile, preferably, the clamping members 3 fixed on the carrier plate 51 are required to be distributed in a continuous and adjacent manner. For example, the fixed clamping members 3 are distributed on the left side, and the movable clamping members 3 are distributed on the right side. The two cooperate to form a clamping ring. The left side of the clamping ring is fixed and unchanged, while the right side can expand and shrink. When the right clamping ring expands, the material tray can be released; when the right clamping ring shrinks, the material tray can be clamped.

[0029] It is understandable that when clamping the material tray 1, the clamping ring can be expanded first so that the material tray 1 can be placed within the clamping range of the clamping ring, and then the clamping ring can be contracted to achieve the clamping effect.

[0030] Preferably, the drive assembly 4 drives the clamping members 3 synchronously, enabling multiple clamping members 3 to operate simultaneously. Specifically, the drive assembly 4 can be a telescopic structure, such as a cylinder or a telescopic motor.

[0031] As a feasible embodiment, each clamping member 3 can correspond to a driving component 4, and multiple driving components 4 can have the same stroke and be driven synchronously.

[0032] As another feasible embodiment, a driving component 4 can work with a transmission structure to drive multiple clamping members 3 simultaneously to achieve synchronous driving; for example, the transmission structure may include a guide rail provided on the carrier plate 51 and a driving link connecting the clamping member 3 and the driving component 4. The clamping member 3 is slidably provided on the guide rail, and the driving component 4 can drive the clamping member 3 to run on the guide rail through the driving link; the multiple guide rails may be distributed in a radial ring.

[0033] It is understandable that when multiple clamping parts 3 are driven synchronously by one driving component 4, the consistency of the ring diameter change of multiple clamping parts 3 during operation should be considered.

[0034] However, in practical applications, two clamping parts 3 on the carrier plate 51 are sufficient to complete the clamping operation of the material tray 1, without the need to set too many clamping parts 3. The following explanation will take setting two clamping parts 3 on the carrier plate 51 as an example.

[0035] In the embodiments of this application, the clamping member 3 clamps the tray 1 using a clamping arc plate 31. The clamping position is the annular wall of the tray 1. The refill paper is wound around the tray 1 in a winding manner. When the clamping arc plate 31 clamps the tray 1, it will directly contact the refill paper. Therefore, this application designs the clamping arc plate 31 as an arc shape so that the clamping arc plate 31 can better fit against the annular wall of the tray 1 for clamping without damaging the refill paper.

[0036] In one specific embodiment, please refer to Figure 4 The clamping member 3 also includes a stop plate 32 and a mounting plate 33. The stop plate 32 is parallel to the carrier plate 51, and the mounting plate 33 is vertically disposed below the stop plate 32. The outer edge of the stop plate 32 is arc-shaped, and the clamping arc plate 31 is vertically disposed at the outer edge of the upper side of the stop plate 32.

[0037] When installing the clamping component 3, adjust the orientation of the clamping arc plate 31 so that it faces the center of the clamping ring, such as... Figure 1 , Figure 3 As shown, the inner side of the arc is clamped to the annular wall corresponding to the material tray 1.

[0038] Due to the radial expansion and contraction of the clamping arc plate 31, the ring diameter of the clamping ring is variable. Preferably, when the clamping ring is at its minimum ring diameter, any two adjacent clamping arc plates 31 do not contact each other.

[0039] Based on the structure of the clamping member 3, when the clamping member 3 is placed on the carrier plate 51, it can be done through the vertical mounting plate 33 to achieve both fixed and movable installation effects.

[0040] The movable installation effect is achieved based on the drive component 4, which can be fixed to the carrier plate 51 radially along the clamping ring, with the telescopic end of the drive component 4 facing outward; the telescopic end is fixed to the inner side of the mounting plate 33, so that the clamping arc plate 31 faces the center of the clamping ring, and the lower end face of the mounting plate 33 just slides in contact with the carrier plate 51; the drive component 4 drives the clamping member 3 to run radially along the clamping ring through the telescopic extension of the telescopic end.

[0041] Specifically, the base structure of the drive assembly 4 is fixed to the carrier plate 51 in a flat, radially fixed manner, while the telescopic shaft is horizontally suspended. The front end of the telescopic shaft can be vertically fixed to the inner center of the mounting plate 33, and the mounting plate 33 slides on the carrier plate 51 in a vertical state. Preferably, the structure of the drive assembly 4 does not extend beyond the stop plate 32 and can be embedded in the carrier plate 51.

[0042] The installation effect during fixation is achieved based on the mounting plate 33. The clamping member 3 is vertically fixed on the carrier plate 51 through the mounting plate 33, so that the stop plate 32 is parallel to the carrier plate 51, and the clamping arc plate 31 faces the center of the clamping ring.

[0043] The vertical height of the mounting plate 33 is used as the installation space for the drive assembly 4, so that the clamping parts 3 installed in two ways can be at the same height, that is, the stop plate 32 is at the same height; when clamping the material tray 1, the material tray 1 can simultaneously abut against the stop plate 32 at different installation positions to maintain the stability of the clamping state.

[0044] In the embodiments of this application, when the drive assembly 4 drives the clamping member 3 to run radially, the clamping of the material tray 1 should be set with a minimum ring diameter to limit the shrinkage limit of the clamping ring and avoid damage to the material tray 1.

[0045] A limit block can be set between the drive assembly 4 and the mounting plate 33. When the telescopic shaft retracts, the limit block will be the first to abut against the mounting plate 33, thereby controlling the retraction limit of the clamping ring.

[0046] In one feasible embodiment, a baffle structure is provided at the front end of the retractable shaft, and the limiting block abuts against the baffle structure to control the shrinkage limit of the clamping ring and prevent the clamping member 3 from falling off the retractable shaft.

[0047] In a preferred embodiment, the drive assembly 4 may include multiple parallel telescopic structures and a connecting plate 41. The telescopic strokes of the two telescopic structures are the same, and the telescopic ends of both telescopic structures are fixedly connected to the connecting plate 41. The connecting plate 41 is fixedly connected to the mounting plate 33. A limiting block for limiting the minimum diameter of the clamping ring is provided between the telescopic structure and the connecting plate 41. The limiting block is fixed to the front end of the telescopic structure and can be located between two telescopic structures. Figure 3 As shown in the image.

[0048] At this time, the connecting plate 41 is fixed by two telescopic shafts, and the limiting block is located between the two telescopic shafts, which can effectively avoid the problem of limiting failure caused by the tilt of the connecting plate 41. Meanwhile, the mounting plate 33 is a vertical straight plate structure, and the connecting plate 41 and the mounting plate 33 can be fitted and fixed together to enhance the fixing effect.

[0049] In the embodiments of this application, the clamping operation of the tray 1 can be completed by simultaneously mounting two clamping members 3 on the carrier plate 51. The installation methods between the two clamping members 3 and the carrier plate 51 include: Firstly, both clamping components 3 are mounted on the carrier plate 51 via the drive assembly 4; that is, all clamping components 3 are mounted on the carrier plate 51 via the drive assembly 4. Secondly, one of the clamping parts 3 is mounted on the carrier plate 51 via the drive assembly 4, while the other is fixed via the mounting plate 33; that is, part of the clamping parts 3 is mounted on the carrier plate 51 via the drive assembly 4.

[0050] Both of the above methods can achieve the clamping operation of the material tray 1. However, it should be clear that the two clamping parts 3 are symmetrically distributed around the center of the carrier plate 51, and the maximum distance between the two clamping parts 3 exceeds the diameter of the material tray 1. That is, the maximum distance between the two clamping arc plates 31 should exceed the diameter of the material tray 1. The minimum distance is limited by the limiting block and can be less than the diameter of the material tray 1 to ensure the stability of clamping.

[0051] In the embodiments of this application, a sensor 2 for detecting the arrival of the tray 1 is provided at the center of the carrier plate 51. The sensor 2 is suspended above the inlet hole 52, and the wire of the sensor 2 can also be introduced through the inlet hole 52.

[0052] Sensor 2 can specifically be a pressure sensor, proximity switch, photoelectric sensor, rangefinder, etc.

[0053] The sensor 2 is located at the center of the clamping ring. When all the clamping parts 3 are installed through the drive assembly 4, the center of the clamping ring is the base of the drive assembly 4. The sensor 2 can be positioned and installed based on the base of the ring-shaped drive assembly 4 or the base of two symmetrically distributed drive assemblies 4.

[0054] For example, the sensor 2 can be mounted between or on the two drive components 4. Depending on the detection requirements of the sensor 2, taking a pressure sensor as an example, the upper surface of the sensor 2 can be flush with the stop plate 32. The sensor 2 corresponds exactly to the central structural ring of the tray 1. When the side of the tray 1 abuts against the stop plate 32, the central structural ring can press on the sensor 2.

[0055] like Figure 1 As shown, the sensor 2 is mounted on two drive components 4. The thickness of the sensor 2 can be the same as the thickness of the stop plate 32 or the thickness of the sensor 2 can be the same as the distance between the upper surface of the drive component 4 and the upper surface of the stop plate 32.

[0056] like Figure 2 As shown, sensor 2 is mounted between two drive components 4, and sensor 2 is suspended above the inlet hole 52.

[0057] When the clamping component 3 is set by the drive assembly 4, the sensor 2 can be installed and fixed based on the clamping component 3 in a fixed state, and can also be set at the center position of the clamping ring.

[0058] When performing the clamping operation of the material tray 1, the drive component 4 can clamp according to the detection signal of the sensor 2 and will not perform invalid clamping actions.

[0059] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0060] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
