Description

Technical Field

[0001] This utility model relates to sorting technology, and more particularly to a roll film feeding mechanism, a wide and narrow film coating equipment, and a sorting machine. Background Technology

[0002] Earphone shells and other paired injection-molded parts are formed in the same mold. However, to avoid mixing up the left and right earphone shells during transit, they need to be packed separately. Currently, workers typically sort the left and right earphone shells and then place them into different packaging boxes. This entire process is done manually and is extremely inefficient.

[0003] To address the aforementioned technical problems, Chinese Patent Application No. CN202311473924.9 discloses a sorting machine for paired injection molded parts, comprising a feeding section, a sorting section, a coating section, and a packing section connected in sequence. The feeding section is used to feed the injection molded parts in pairs. The sorting section is used to sort and arrange the paired injection molded parts on the coating section, including two pickers arranged side-by-side, and an arrangement motion mechanism connecting and driving the two pickers between the feeding section and the coating section. The coating section is used to cover the sorted and arranged injection molded parts with a protective film to form two coated injection molded parts, including two coating channels arranged side-by-side, one coating channel corresponding to one picker. The packing section is used to pack the two coated injection molded parts separately. Placed in a packaging box; wherein, the laminating section includes a laminating table, two laminating channels formed on the laminating table, and a lower film roll located below the laminating table for loading two rolls of lower protective film side by side, one roll of lower protective film corresponding to one laminating channel; an upper film roll located above the laminating table for loading two rolls of upper protective film side by side, one roll of upper protective film corresponding to one laminating channel; an edge sealing module and a film cutting module located behind the laminating table for sealing the corresponding edges of the two sets of upper and lower protective films and cutting the edge seals on the two sets of upper and lower protective films, respectively; a film pulling module located behind the edge sealing module and the film cutting module for pulling the two sets of upper and lower protective films with single-sided edge sealing, together with the injection molded parts sorted and arranged on the two rolls of lower protective film, into the packing section.

[0004] In the sorting machine described above, the lower film roll and the upper film roll each load two protective films side by side. After leaving the roll, the two protective films are prone to shifting in position during the feeding process due to uneven tension and other factors, which can cause them to become tangled together, requiring the machine to be stopped for processing and affecting efficiency. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides a film feeding mechanism that can effectively prevent two parallel protective films from becoming entangled due to positional shifts after leaving the roll shaft.

[0006] This utility model also provides a wide and narrow film coating equipment and a sorting machine, including the above-mentioned roll film feeding mechanism.

[0007] The technical problem to be solved by this utility model is achieved through the following technical solution:

[0008] A film feeding mechanism includes a film spool and a guide roller arranged relatively parallel to each other. The film spool has a first roll position and a second roll position arranged side by side along the axial direction. The guide roller is fitted with a guide spacer. The guide spacer is perpendicular to the axial direction of the guide roller and can be adjusted in position along the axial direction of the guide roller to divide the guide roller into a first guide position and a second guide position corresponding to the first roll position and the second roll position, respectively.

[0009] Furthermore, the guide roller is fitted with two first clamping members, which respectively abut against the two side surfaces of the guide spacer and are clamped and fixed to the guide roller.

[0010] Furthermore, a material spacer is sleeved on the roll shaft. The material spacer is perpendicular to the axial direction of the roll shaft and can be adjusted in position along the axial direction of the guide roller to divide the roll shaft into the first roll position and the second roll position in the axial direction.

[0011] Furthermore, two second clamping members are sleeved on the roll shaft, and the two second clamping members abut against the two side surfaces of the roll spacer and are clamped and fixed to the roll shaft.

[0012] Furthermore, a first baffle ring and a second baffle ring are also sleeved on the roll shaft. The first baffle ring is located on the side opposite to the first roll position and the roll spacer ring, and the second baffle ring is located on the side opposite to the second roll position and the roll spacer ring.

[0013] Furthermore, the film feeding mechanism also includes a feeding bracket, on which the film roll shaft and the guide roller are rotatably mounted.

[0014] A wide and narrow film laminating device includes a laminating table, two laminating channels formed on the laminating table, and

[0015] The upper film feeding mechanism is located above the film coating table and is used to load two rolls of upper protective film side by side along the axial direction. One roll of lower protective film corresponds to one film coating channel.

[0016] The lower roll film loading mechanism is located below the film coating table and is used to load two rolls of lower protective film side by side along the axial direction. One roll of lower protective film corresponds to one film coating channel.

[0017] The edge sealing mechanism and the film cutting mechanism are located behind the film covering table and are used to seal the corresponding edges of the two sets of upper and lower protective films and to cut the edges on the two sets of upper and lower protective films, respectively.

[0018] The film pulling mechanism, located behind the sealing mechanism and the film cutting mechanism, is used to pull the two sets of upper and lower protective films for sealing one side of the edge backward from the sealing mechanism and the film cutting mechanism;

[0019] At least one of the upper film feeding mechanism and the lower film feeding mechanism adopts the film feeding mechanism described above.

[0020] Furthermore, the widths between the two upper protective films are different, the widths between the two lower protective films are different, and the widths between the upper and lower protective films corresponding to the same coating channel are the same.

[0021] Furthermore, the film-pulling mechanism includes two sets of film-pulling grippers and a film-pulling motion assembly that connects and drives the two sets of film-pulling grippers to move relative to the sealing mechanism and the film-cutting mechanism. Each set of film-pulling grippers corresponds to a film-coating channel. The positions of the two sets of film-pulling grippers on the film-pulling motion assembly are adjustable to adapt to the widths of the upper and lower protective films of the corresponding film-coating channels, respectively.

[0022] A sorting machine includes a product feeding device, a product sorting device, the aforementioned wide and narrow film coating device, and a finished product packing device connected in sequence.

[0023] The product feeding equipment is used for feeding injection molded products in pairs;

[0024] The product sorting equipment is used to sort and arrange the injection molded products that are fed in pairs on the wide and narrow film coating equipment. It includes two pickers arranged side by side, and a sorting motion mechanism that connects and drives the two pickers to move between the product feeding equipment and the wide and narrow film coating equipment. One picker corresponds to the sorting of one coating channel.

[0025] The wide and narrow film coating equipment is used to cover the injection molded product with an upper protective film and a lower protective film respectively to form two coated finished products;

[0026] The finished product packing equipment is used to place two laminated finished products into their respective packaging boxes.

[0027] The present invention has the following beneficial effects: The film feeding mechanism of the present invention, by sleeved with the guide spacer on the guide roller, divides the guide roller into a first guide position and a second guide position in the axial direction, which correspond to the first roll position and the second roll position on the roll shaft, respectively. When feeding the film, two rolls of protective film are loaded side by side on the first roll position and the second roll position on the roll shaft, respectively. Then, the two rolls of protective film are pulled out and wound onto the first guide position and the second guide position on the guide roller, respectively. Since the two rolls of protective film are separated by the guide spacer on the guide roller after leaving the roll shaft, they can be prevented from tangling together due to positional displacement.

[0039] Example 1

[0040] like Figure 1 and 2 As shown, a film feeding mechanism includes a film winding shaft 301 and a guide roller 302 arranged relatively parallel to each other. The film winding shaft 301 has a first film winding position 301a and a second film winding position 301b arranged side by side along the axial direction. The guide roller 302 is fitted with a guide spacer 303, which is perpendicular to the axial direction of the guide roller 302 and can be adjusted in position along the axial direction of the guide roller 302 to divide the guide roller 302 into a first guide position 302a and a second guide position 302b corresponding to the first film winding position 301a and the second film winding position 301b, respectively.

[0041] The film feeding mechanism of this utility model divides the guide roller 302 into a first guide position 302a and a second guide position 302b along the axial direction by sleeved with the guide spacer 303 on the guide roller 302. These positions correspond to the first roll position 301a and the second roll position 301b on the roll shaft 301, respectively. During film feeding, two rolls of protective film 30a and 30b are loaded side by side on the first roll position 301a and the second roll position 301b of the roll shaft 301, respectively. Then, the two rolls of protective film 30a and 30b are pulled out and wound onto the first guide position 302a and the second guide position 302b of the guide roller 302, respectively. Since the two rolls of protective film 30a and 30b are separated by the guide spacer 303 on the guide roller 302 after leaving the roll shaft 301, they can be prevented from tangling together due to positional displacement.

[0042] In this embodiment, the guide roller 302 is located below the roll shaft 301. However, depending on the different feeding and conveying requirements of the protective films 30a and 30b, the guide roller 302 may also be located above, in front of, or behind the roll shaft 301.

[0043] In this embodiment, there is only one guide roller 302. However, depending on the different feeding and conveying paths of the protective films 30a and 30b, there may be two or more guide rollers 302, and at least one guide roller 302 is fitted with the guide spacer 303.

[0044] The guide ring 303 can be adjusted in position along the axial direction of the guide roller 302, thereby adjusting its position on the guide roller 302 according to the width of the two rolls of protective film 30a and 30b, and fixing its position after the position adjustment is completed.

[0045] Two first clamping members 305 are sleeved on the guide roller 302. The two first clamping members 305 abut against the two side surfaces of the guide spacer 303 and are clamped and fixed to the guide roller 302.

[0046] The first clamping member 305 can clamp or loosen relative to the guide roller 302, and after clamping the guide roller 302, the position between it and the guide roller 302 is fixed; after the two first clamping members 305 clamp the guide roller 302 respectively, they abut from the left and right sides to clamp the guide spacer 303, thereby fixing the position of the guide spacer 303 on the guide roller 302.

[0047] In this embodiment, the first clamping member 305 may be, but is not limited to, a clamp or a rubber ring.

[0048] In some examples, the guide ring 303 may not be fixed in position. Its position on the guide roller 302 may be maintained by the tension of the two rolls of protective film 30a and 30b during the output feeding, or it may be offset synchronously according to the offset of the two rolls of protective film 30a and 30b on the guide roller 302, as long as the two rolls of protective film 30a and 30b can be separated.

[0049] Preferably, a material spacer 304 is sleeved on the material roll shaft 301. The material spacer 304 is perpendicular to the axial direction of the material roll shaft 301 and can be adjusted in position along the axial direction of the guide roller 302 to divide the material roll shaft 301 into the first material roll position 301a and the second material roll position 301b in the axial direction.

[0050] The roll spacer 304 is used to separate the two rolls of protective film 30a and 30b on the roll shaft 301 from each other to prevent the two rolls of protective film 30a and 30b from contacting each other due to positional misalignment, and to further prevent the two rolls of protective film 30a and 30b from tangling together due to positional misalignment.

[0051] The spacer ring 304 can be adjusted in position along the axial direction of the roll shaft 301, thereby adjusting its position on the roll shaft 301 according to the width of the two rolls of protective film 30a and 30b, and fixing its position after the position adjustment is completed.

[0052] Two second clamping members 306 are sleeved on the roll shaft 301. The two second clamping members 306 abut against the two side surfaces of the roll spacer 304 and are clamped and fixed to the roll shaft 301.

[0053] The second clamping member 306 can be clamped or released relative to the roll shaft 301, and after clamping the roll shaft 301, its position with the roll shaft 301 is fixed; after the two second clamping members 306 are respectively clamped on the roll shaft 301, they abut from the left and right sides to clamp the roll spacer 304, thereby fixing the position of the roll spacer 304 on the roll shaft 301.

[0054] In this embodiment, the second clamping member 306 may be, but is not limited to, a clamp or a rubber ring.

[0055] In some examples, the roll spacer 304 may not be fixed in position. Its position on the roll shaft 301 may be maintained by the support force of the two rolls of protective film 30a and 30b in the width direction, or it may be offset synchronously according to the offset of the two rolls of protective film 30a and 30b on the roll shaft 301, as long as the two rolls of protective film 30a and 30b can be separated.

[0056] Preferably, the roll shaft 301 is further fitted with a first baffle ring 307 and a second baffle ring 308. The first baffle ring 307 is located on the side opposite to the first roll position 301a and the roll spacer 304, and the second baffle ring 308 is located on the side opposite to the second roll position 301b and the roll spacer 304.

[0057] The first baffle ring 307 and the second baffle ring 308 can cooperate with the roll spacer ring 304 to define the position and width of the first roll position 301a and the second roll position 301b on the roll shaft 301, and respectively limit the position of the two rolls of protective film 30a and 30b on the roll shaft 301 to prevent the two rolls of protective film 30a and 30b from shifting position on the roll shaft 301.

[0058] Similar to the roll spacer 304, the first baffle ring 307 and the second baffle ring 308 can also be adjusted in position along the axial direction of the roll shaft 301, so as to adjust their position on the roll shaft 301 according to the width of the two rolls of protective film 30a and 30b, and fix their position by clamps or rubber rings after the position adjustment is completed.

[0059] The film feeding mechanism also includes a feeding bracket 309, on which the film shaft 301 and the guide roller 302 are rotatably mounted.

[0060] The feeding bracket 309 includes two bracket sidewalls 309a and 309b. One bracket sidewall 309a is located on one end of the winding shaft 301 and the guide roller 302 along the axial direction and is rotatably connected to one end of the winding shaft 301 and the guide roller 302. The other bracket sidewall 309b is located on the other end of the winding shaft 301 and the guide roller 302 along the axial direction and is rotatably connected to the other end of the winding shaft 301 and the guide roller 302.

[0061] In some examples, if the guide roller 302 is located in front of or behind the roll shaft 301, the two support sidewalls 309a and 309b can be divided into front and rear sidewalls. One end of the roll shaft 301 and the guide roller 302 are respectively rotatably connected to the two sidewalls of the support sidewall 309a on one side, and the other end of the roll shaft 301 and the guide roller 302 are respectively rotatably connected to the two sidewalls of the support sidewall 309b on the other side.

[0062] In some examples, the feeding bracket 309 further includes a bracket base (not shown in the figure), and the bracket sidewalls 309a and 309b are fixedly disposed on the bracket base.

[0063] Example 2

[0064] like Figure 3 As shown, a wide and narrow film laminating device includes a laminating table 31, two laminating channels formed on the laminating table 31, and

[0065] The upper film feeding mechanism 32 is located above the film coating table 31 and is used to load two rolls of upper protective film 320 in parallel along the axial direction. One roll of lower protective film 330 corresponds to one film coating channel.

[0066] The lower roll film loading mechanism 33 is located below the film coating table 31 and is used to load two rolls of lower protective film 330 in parallel along the axial direction. One roll of lower protective film 330 corresponds to one film coating channel.

[0067] The sealing mechanism 34 and the film cutting mechanism 35 are located behind the film covering table 31 and are used to seal the corresponding edges of the two sets of upper protective films 320 and lower protective films 330 and to cut the sealed edges on the two sets of upper protective films 320 and lower protective films 330, respectively.

[0068] The film pulling mechanism 36 is located behind the sealing mechanism 34 and the film cutting mechanism 35, and is used to pull the two sets of upper protective film 320 and lower protective film 330 of the single-sided sealing mechanism backward from the sealing mechanism 34 and the film cutting mechanism 35.

[0069] In this embodiment, at least one of the upper film feeding mechanism 32 and the lower film feeding mechanism 33 adopts the film feeding mechanism described in Embodiment 1.

[0070] During lamination, two rolls of lower protective film 330 are loaded side-by-side onto the roll shaft 301 of the lower film loading mechanism 33, and two rolls of upper protective film 320 are loaded side-by-side onto the roll shaft 301 of the upper film loading mechanism 32. Then, the two rolls of lower protective film 330 and the two rolls of upper protective film 320 are pulled out via the guide rollers 302 of the lower film loading mechanism 33 and the upper film loading mechanism 32, respectively. The two rolls of lower protective film 330 are then fed through their respective lamination channels on the lamination table 31. The two rolls of upper protective film 320 are directly fed into the sealing mechanism 34 and the film cutting mechanism 35, so that the two sets of upper protective film 320 and lower protective film 330 are respectively stacked together in the sealing mechanism 34 and the film cutting mechanism 35. Then, initialization is performed. The sealing mechanism 34 seals the edges of the two sets of upper protective film 320 and lower protective film 330, and the film cutting mechanism 35 cuts the sealed edges of the two sets of upper protective film 320 and lower protective film 330 from the middle (leaving half of the sealed edge in each set). The upper protective film 320 and lower protective film 330 serve as the edge seals for one side of the two laminated finished products, with half of the edge seal removed as waste. After the sorting equipment completes the sorting of injection-molded products on the two rolls of lower protective film 330 on the laminating table 31, the edge sealing mechanism 34 loosens the edge seals on the two sets of upper protective film 320 and lower protective film 330, and the film pulling mechanism 36 pulls the edge seals on the two sets of upper protective film 320 and lower protective film 330 together to pull out the two sets of upper protective film 320 and lower protective film 330 with one side sealed (until packaging). (Inside the equipment); Finally, the sealing mechanism 34 seals the other side of the two sets of upper protective films 320 and lower protective films 330 again, and the film cutting mechanism 35 cuts the sealing edge on the other side of the two sets of upper protective films 320 and lower protective films 330 from the middle (half of the sealing edge is left on the two sets of upper protective films 320 and lower protective films 330 located in the film coating table 31 as one side sealing edge of the next film coating product, and half of the sealing edge is left on the two sets of upper protective films 320 and lower protective films 330 that have been pulled out as the other side sealing edge of the previous film coating product).

[0071] In some examples, the widths between the two rolls of upper protective film 320 are different, the widths between the two rolls of lower protective film 330 are different, and the widths between the upper protective film 320 and the lower protective film 330 corresponding to the same coating channel are the same.

[0072] Preferably, Figure 4As shown, the film-pulling mechanism 36 includes two sets of film-pulling grippers 361a and 361b, and a film-pulling motion assembly 362 that connects and drives the two sets of film-pulling grippers 361a and 361b to move relative to the sealing mechanism 34 and the film-cutting mechanism 35. Each set of film-pulling grippers 361a corresponds to one film-coating channel. The positions of the two sets of film-pulling grippers 361b on the film-pulling motion assembly 362 are adjustable to adapt to the widths of the upper protective film 320 and the lower protective film 330 of the corresponding film-coating channel, respectively.

[0073] Example 3

[0074] like Figure 5 and 6 As shown, a sorting machine includes a product feeding device 1, a product sorting device 2, a wide and narrow film coating device 3 as described in Embodiment 2, and a finished product packing device 4, connected in sequence.

[0075] The product feeding equipment 1 is used for feeding injection molded products in pairs;

[0076] The product sorting equipment 2 is used to sort and arrange the injection molded products that are fed in pairs on the wide and narrow film coating equipment 3. It includes two pickers 21 arranged in parallel, and a sorting motion mechanism 22 that connects and drives the two pickers 21 to move between the product feeding equipment 1 and the wide and narrow film coating equipment 3. One picker 21 corresponds to the sorting of one coating channel.

[0077] The wide and narrow film coating equipment 3 is used to cover the injection molded product with an upper protective film 320 and a lower protective film 330 respectively to form two coated finished products;

[0078] The finished product packing equipment 4 is used to put the two laminated finished products into their respective packaging boxes.

[0079] like Figure 7 As shown, the finished product packing equipment 4 includes a finished product picking and placing mechanism 41 located above the film pulling mechanism 36 of the wide and narrow film coating equipment 3, a box placement mechanism 42 located below the film pulling mechanism 36 of the wide and narrow film coating equipment 3, a picking and placing lifting mechanism 43 connected to drive the finished product picking and placing mechanism 41 to lift and lower, and a box translation mechanism 44 connected to drive the box placement mechanism 42 to translate.

[0080] When the film-pulling motion component 362 drives the two sets of film-pulling grippers 361a and 361b to move closer to the sealing mechanism 34 and the film-cutting mechanism 35, the two sets of film-pulling grippers 361a and 361b are located on the side of the finished product packaging equipment 4 closest to the wide and narrow film laminating equipment 3, so as to grab one side of the two sets of upper protective film 320 and lower protective film 330 respectively for sealing; when the film-pulling motion component 362 drives the two sets of film-pulling grippers 361a and 361b to move away from the sealing mechanism 34 and the film-cutting mechanism 35, the two sets of film-pulling grippers 361a and 361b are located on the side of the finished product packaging equipment 4 away from the wide and narrow film laminating equipment 3, so as to pull the two sets of upper protective film 320 and lower protective film 330 together to the space between the finished product picking and placing mechanism 41 and the box placement mechanism 42.

[0081] When the lifting mechanism 43 raises the finished product picking and placing mechanism 41, the finished product picking and placing mechanism 41 is positioned above the film pulling mechanism 36 to grab the two sets of upper protective film 320 and lower protective film 330 pulled out by the film pulling mechanism 36; when the lifting mechanism 43 lowers the finished product picking and placing mechanism 41, the finished product picking and placing mechanism 41 is positioned below the film pulling mechanism 36 to place the two sets of upper protective film 320 and lower protective film 330 into the packaging box located on the box placement mechanism 42; the box translation mechanism 44 then drives the box placement mechanism 42 to translate, so that the packaging box placed on the box placement mechanism 42 is aligned with the finished product picking and placing mechanism 41.

[0082] The finished product picking and placing mechanism 41 includes two sets of telescopic pins, with each set of telescopic pins arranged crosswise. Each set of telescopic pins corresponds to a film-coating channel. The positions of the two sets of telescopic pins on the picking and placing lifting mechanism 43 are adjustable to adapt to the widths of the upper protective film 320 and the lower protective film 330 of the corresponding film-coating channel, respectively.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present utility model, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the present utility model.
