Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lid conveying equipment, and in particular to a pre-positioning conveying equipment for irregularly shaped lids. Background Technology
[0002] In the packaging container manufacturing industry, especially in food and daily chemical industries, irregularly shaped container caps with handles (hereinafter referred to as "irregular caps") are commonly used. These caps are usually designed with handle-like structures for easy gripping, opening, or positioning with the bottle body. To improve product appearance and brand recognition, patterns, text, or logos are often printed on the top of the cap during the production process. This requires the printed pattern to be centered and at a consistent angle relative to the cap body (especially its handles) to meet aesthetic and standardization requirements.
[0003] Currently, the automated conveying and printing of large quantities of stacked irregularly shaped caps presents the following common technical challenges: After the caps are output one by one from the hopper or stack via a vibratory feeder or conveyor line, the orientation of their handles is random. If the handle orientation is not standardized and corrected before entering the printing station, printing will result in significant deviations in the position of the printed pattern relative to the handles, such as the pattern deviating from the center or rotating. This not only severely affects the consistency of the product's appearance but may also render the product unusable due to pattern misalignment (e.g., alignment marks becoming ineffective), and even increase the scrap rate.
[0004] In existing technologies, two methods are typically used to solve the orientation problem of irregularly shaped caps: One is to install complex mechanical steering or picking mechanisms in the middle of the conveyor line or before the printing station, using sensors to detect the position of the cap's "ear" and then correcting it one by one using a robotic arm or rotating mechanism. This method involves complex equipment structure, occupies a large space, is inconvenient to adjust and maintain, and significantly affects the cap's conveying speed, resulting in low efficiency. The second method relies on subsequent stations (such as vision-positioning printing machines) for high-precision online identification and dynamic adjustment. However, this greatly increases equipment cost and system complexity, places extremely high demands on the control system, and still cannot fundamentally solve the initial positioning problem caused by the chaotic state of the caps before entering the printing unit, resulting in insufficient stability before printing.
[0005] Therefore, how to automatically guide the ears of irregularly shaped caps in a simple, efficient and reliable manner during the early stages of forward conveying, especially in the continuous and stable conveying process, to achieve precise pre-positioning and thus provide caps with consistent orientation and centered position for subsequent printing processes, has become a technical problem to be solved in this field. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide a pre-positioning conveying device for irregularly shaped covers.
[0007] To achieve the above objectives, this utility model discloses a pre-positioning conveying device for irregularly shaped caps, comprising a pair of rotary belts, a frame, a guiding module, and a cap-picking module. The pair of rotary belts are symmetrically tensioned on the frame. Side baffles are provided on the outer surfaces of the rotary belts, forming a first receiving channel between the side baffles and the rotary belts, and a second receiving channel between the pair of rotary belts. Stacked irregularly shaped caps are horizontally arranged in the first receiving channel, and the ears of the irregularly shaped caps are arranged in the second receiving channel. The cap-picking module is fixedly arranged at the end of the first receiving channel. The cap-picking module is used to pick up the irregularly shaped cap located at the end of the first receiving channel and place it on the conveying device.
[0008] The guiding module is located at the end of the second accommodating channel. The guiding module includes an adjusting rod and a pair of guiding plates. The adjusting rod is rotatably mounted in the second accommodating channel. The pair of guiding plates are symmetrically mounted on the adjusting rod, and a guiding channel is formed between the pair of guiding plates.
[0009] The rotary belt is driven by the drive module to rotate, thereby causing the stacked irregularly shaped covers to slide along the first accommodating channel and the second accommodating channel. When the ear of the irregularly shaped cover moves to the end of the second accommodating channel, it slides along the guide channel. At this time, the two sides of the ear are limited between a pair of guide plates to achieve alignment.
[0010] Furthermore, it also includes a separation module, which is disposed above the first accommodating channel. The separation module includes a separation shaft, which is connected to the drive module via a linkage module. The separation shaft is provided with a screw groove. When the separation shaft rotates, it separates the stacked irregular-shaped covers laterally so that the top of the irregular-shaped covers is in the screw groove.
[0011] Furthermore, the outer periphery of the adjusting rod has a positive tooth section and a negative tooth section, and a pair of guide plates are respectively connected to the positive tooth section and the negative tooth section for transmission.
[0012] Furthermore, the guide plate is provided with a first guide slope and a second guide slope on the side of the guide channel, so that the beginning and end of the guide channel are respectively flared.
[0013] Furthermore, a plurality of baffle plates are provided at the end of the first accommodating channel, and a support frame is fixedly provided on the frame. The plurality of baffle plates are distributed on the support frame with the irregularly shaped cover as the center, and the baffle plates are used to support the last irregularly shaped cover at the end of the first accommodating channel.
[0014] The side of the cover plate that is tangent to the irregularly shaped cover is arranged in an arc shape.
[0015] Furthermore, the separation module also includes a pair of brushes, which are symmetrically fixed on both sides of the separation shaft. The brushes are in contact with the irregularly shaped cover in the first accommodating channel to assist in fixing.
[0016] Furthermore, the end of the separating shaft extends to the end of the first receiving channel, and the outer periphery of the separating shaft is provided with helical blades. The helical blades form the helical grooves on the separating shaft, and the stacked irregular caps are spirally conveyed forward through the helical blades and separated one by one into the corresponding helical grooves.
[0017] Furthermore, the width of the screw groove is greater than or equal to the width of the irregular cap.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. Utilizing the structural features (ears) of the irregularly shaped caps, each stacked irregularly shaped cap is simultaneously transported during the conveying process to achieve a pre-positioning effect of the printed pattern on the printing surface of the irregularly shaped cap (calibration of printing direction and angle).
[0020] 2. When conveying irregularly shaped caps of different specifications, rotate the adjusting rod to make a pair of guides close or far apart, and change the width of the guide channel to adapt to the ear. This equipment has good adaptability and is easy to adjust.
[0021] 3. The stacked irregularly shaped caps are separated by spiral blades and placed into the corresponding screw grooves, thereby controlling the spacing between two adjacent caps and avoiding the suction of two caps at once and the empty suction action. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will be combined with... Figures 1-4 The accompanying drawings provide a further detailed description of this utility model.
[0027] Reference Figures 1-3As shown, a pre-positioning conveying device for irregularly shaped caps includes a pair of rotary belts 1, a frame 2, a guiding module 3, a separating module 4, and a cap-retrieving module 5. The pair of rotary belts 1 are symmetrically tensioned on the frame 2, specifically, the top surface of the rotary belts 1 is higher than the top of the frame 2. A drive module 6 is fixedly installed at the bottom of the frame 2, and the drive module 6 is connected to one end of the rotary belts 1 for transmission, driving the two rotary belts 1 to rotate synchronously.
[0028] It should be noted that the connection structure between the rotary belt 1 and the frame 2 in this embodiment is a known technology; the connection structure between the rotary belt 1 and the drive module 6 is a known technology and will not be described here.
[0029] Each of the two rotary belts 1 has a side baffle 11 on its outer side. Specifically, the side baffle 11 is fixedly installed on the top of the frame 2, and a first receiving channel 7 is formed between the side baffle 11 and the top surface of the rotary belt 1. The cap picking module 5 is installed on the side of the frame 2 along the conveying direction of the irregular cap 9. The cap picking module 5 is used to pick up the last irregular cap 9 located at the end of the first receiving channel 7 and pick it up and place it on the conveying equipment (not shown in the figure) to convey it forward into the printing process.
[0030] In this embodiment, the cap-removing module 5 is a cap-removing structure using a robotic arm and a suction rod. This is a well-known technology and will not be described further here.
[0031] Furthermore, the space between the two rotating belts 1 forms a second receiving channel 8, which is connected to the first receiving channel 7. During operation, the stacked irregularly shaped covers 9 are placed in the first receiving channel 7. At this time, the outer periphery of the irregularly shaped covers 9 is tangent to the rotating belt 1 and the side baffle 11. Meanwhile, the ear portion 91 of the irregularly shaped covers 9 is located in the second receiving channel 8.
[0032] Reference Figure 2 , Figure 4 As shown, the guide module 3 is located at the end of the second receiving channel 8. The guide module 3 includes an adjusting rod 31 and a pair of guide plates 32. In this embodiment, the adjusting rod 31 is a forward and reverse threaded rod. The adjusting rod 31 is longitudinally arranged in the second receiving channel 8, and the outer peripheries of both ends of the adjusting rod 31 are rotatably connected to the frame 2 through bearing seats (not shown in the figure). A pair of guide plates 32 are symmetrically arranged on the adjusting rod 31. Specifically, the two guide plates 32 are respectively connected to the forward and reverse threaded sections on the adjusting rod 31. When the adjusting rod 31 rotates, it drives the pair of guide plates 32 to move closer or further apart.
[0033] A guiding channel 321 is formed between a pair of guiding plates 32. A first guiding slope 322 and a second guiding slope 323 are provided on the side of the guiding plates 32 within the guiding channel 321. The first guiding slope 322 and the second guiding slope 323 are respectively arranged at the beginning and end of the inner side of the guiding plate 32 along the conveying direction of the irregularly shaped cover 9. In this embodiment, the first guiding slope 322 and the second guiding slope 323 make the beginning and end of the guiding channel 321 flared outwards, thereby facilitating the input and output of the ear portion 91 of the irregularly shaped cover 9.
[0034] Reference Figure 1 As shown, further, a plurality of baffle plates 71 are provided at the end of the first receiving channel 7. In this embodiment, the number of baffle plates 71 is three. Specifically, a support frame 21 is fixedly provided on the frame 2. The three baffle plates 71 are distributed on the support frame 21 with the irregular cover 9 as the center, and they are respectively tangent to the outer periphery of the irregular cover 9 at the end of the first receiving channel 7. The baffle plates 71 abut against the irregular cover 9 at the end of the first receiving channel 7 to prevent it from tilting downward.
[0035] The side of the baffle plate 71 that is tangent to the irregular cover 9 is set in an arc shape to prevent the irregular cover 9 from being damaged or deformed due to interference between the irregular cover 9 and the baffle plate 71 when the cover removal module 5 performs a suction action to take the irregular cover 9 away from the first receiving channel 7.
[0036] Reference Figures 1-4 As shown, during operation, the drive module 6 drives a pair of rotary belts 1 to rotate, and at the same time drives the irregular cover 9 to move forward in the first receiving channel 7. At this time, the ear 91 of the irregular cover 9 moves along the second receiving channel 8.
[0037] As the irregularly shaped cap 9 moves to the end of the first receiving channel 7, the ear portion 91 of the irregularly shaped cap 9 gradually enters the guiding channel 321 for guiding. Specifically, the side of the ear portion 91 of the irregularly shaped cap 9 slides along the guiding plate 32. The rotational freedom of the irregularly shaped cap 9 is restricted by a pair of guiding plates 32, thereby achieving the pre-positioning function of the irregularly shaped cap 9 before printing. This embodiment utilizes the structural characteristics (ear portion 91) of the irregularly shaped cap 9 to synchronously guide each stacked irregularly shaped cap 9 during the conveying process, so as to achieve the pre-positioning effect of the printed pattern on the printing surface of the irregularly shaped cap (calibration of printing direction and angle).
[0038] When conveying irregularly shaped covers 9 of different specifications, the adjusting rod 31 is rotated to bring a pair of guide plates 32 closer or further apart, thereby changing the width of the guide channel 321 to accommodate the ear 91, making the equipment adaptable and easy to adjust.
[0039] Reference Figure 3As shown, the separation module 4 includes a separation shaft 41 and a pair of brushes 42. The separation shaft 41 is rotatably positioned above the first accommodating channel 7, and the pair of brushes 42 are symmetrically fixed on both sides of the separation shaft 41. The brushes 42 are in contact with the irregularly shaped cover 9 inside the first accommodating channel 7 to provide auxiliary fixation. Specifically, the end of the separation shaft 41 is connected to the drive module 6 via a linkage module (not shown in the figure) to achieve linkage between the separation shaft 41 and the rotary belt 1 to ensure synchronization.
[0040] The linkage module in this embodiment uses common connection methods such as belts and chains, which are known technologies and will not be described further here.
[0041] The end of the separating shaft 41 extends to the end of the first receiving channel 7. A helical blade 411 is provided on the outer periphery of the separating shaft 41, and the helical blade 411 forms a screw groove 412 in the separating shaft 41. In this embodiment, the width of the screw groove 412 is greater than or equal to the width of the irregular cover 9.
[0042] During operation, the separating shaft 41 rotates synchronously with the rotating belt 1. The irregularly shaped cover 9 in the first accommodating channel 7 slides along the outer periphery of the separating shaft 41. As the separating shaft 41 rotates, the spiral blades 411 separate two adjacent irregularly shaped covers 9 and accommodate them in the corresponding screw grooves 412. Specifically, the bottom of the irregularly shaped cover 9 slides along the rotating belt 1, its two sides slide along the side baffles 11, and its top is in the corresponding screw groove 412. At the same time, the screw groove 412 limits the irregularly shaped cover 9.
[0043] In this embodiment, the stacked irregularly shaped caps 9 are spirally conveyed and separated by setting spiral blades 411 and accommodated in the corresponding spiral grooves 412, thereby controlling the spacing between two adjacent caps and avoiding the suction of two caps at once and the empty suction action.
[0044] It should be noted that the ear shape of the irregularly shaped cover in this embodiment is not limited to the shape shown in the attached drawings. This device can adapt to irregularly shaped covers with ear shapes such as triangles, squares and trapezoids.
[0045] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They cannot be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit of the main technical solution of this utility model should be covered within the protection scope of this utility model.
