A method for peeling raw film

Abstract

The present invention discloses a method for stripping raw rubber sheets. The separator is a flexible flat plate structure, comprising a first side surface and a second side surface; the roughness of the first side surface is greater than that of the second side surface; and the raw material pile comprises a plurality of the separators and a plurality of raw rubber sheets arranged in an alternating manner. The method includes placing the raw material pile with the first side surface of each separator facing upward; flipping the separator at the top of the raw material pile to separate it from the adjacent raw rubber sheets below it; and repeatedly flipping the separator at the top of the raw material pile to separate it from the adjacent raw rubber sheets below it, so that the raw rubber sheets adhered to the upper side of the separator are placed downward. By placing the raw material pile with the first side surface of the separator having a greater roughness facing upward, the raw rubber sheets on the upper side of the separator are less likely to fall off when the separator is flipped from its upper side to its lower side, thereby improving the reliability of the raw rubber sheet stripping process.

Description

Technical Field

[0001] The invention belongs to the technical field of rubber plug vulcanization, and in particular relates to a method for stripping a raw rubber sheet. Background Art

[0002] In the current production process of pharmaceutical rubber plugs, the raw rubber sheets before vulcanization are very sticky. To prevent the raw rubber sheets from sticking together, they are separated by partitions. That is, the raw rubber sheets and the partitions are stacked one by one, and the partitions are manually separated from the rubber sheets when they are used.

[0003] In existing technology, thicker separators are easier to separate from the raw film. However, their poor flexibility makes flipping difficult and prone to damage during flipping, making automation difficult. Furthermore, when the stack of films and separators is formed, the lower raw film is under pressure, causing the raw film to randomly stick to the upper or lower separator when flipped open. This creates uncertainty about the location of the raw film when flipped and separated, making flipping and separation difficult. Therefore, the automation and reliability of the separation process for the raw film and separators are urgently needed. Summary of the Invention

[0004] The invention provides a method for stripping raw rubber sheets, which adopts a flexible partition and places the side of the partition with greater roughness upward in a raw material pile, thereby improving the reliability and production efficiency of separating the raw rubber sheets and the partition by turning the partition.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A method for stripping a raw film, comprising:

[0007] The partition is a flexible flat plate structure, including a first side surface and a second side surface; the roughness of the first side surface is greater than the roughness of the second side surface; at least one raw material pile is placed with the first side surface of each partition facing upward; the raw material pile includes a plurality of the partitions and a plurality of raw rubber sheets arranged in an alternating manner;

[0008] Turning over the partition located at the uppermost layer of the raw material pile to separate it from the adjacent raw rubber sheet located therebelow;

[0009] Repeatedly flip the partition located at the top of the raw material pile to separate it from the raw rubber sheet located below and adjacent to it, and place the raw rubber sheet adhered to the upper side of the partition downward.

[0010] In a specific embodiment, it also includes:

[0011] placing the separator with the raw film adhered thereto with the raw film facing downward on a raw film placement table;

[0012] The raw film placement table absorbs the raw film on its upper side;

[0013] The partition on the raw film placement table is flipped from one end to the other end to separate it from the raw film located below it.

[0014] In a specific embodiment, it also includes:

[0015] After the raw film is completely separated from the partition, the raw film placement table cancels the adsorption of the raw film thereon.

[0016] In a specific embodiment, it further includes:

[0017] placing the separator with the raw film adhered thereto with the raw film facing downward on a raw film placement table;

[0018] Turning over the partition on the raw film placement table from one end to the other end until one end of the raw film on the lower side thereof is exposed and the partition stops;

[0019] The raw film placement table presses the exposed end of the raw film located on the upper side thereof;

[0020] Continue to flip the partition on the raw film placement table from one end to the other end to completely separate it from the raw film located below it.

[0021] In a specific embodiment, it further includes:

[0022] After the raw film is completely separated from the partition, the pressing of one end of the raw film on the raw film placement table is cancelled.

[0023] In some specific embodiments, the method further includes stacking the raw material piles;

[0024] The raw rubber sheet is rectangular; the partition is a rectangle whose length is greater than that of the raw rubber sheet; when the raw material pile is stacked, the length of the raw rubber sheet corresponds to the length of the partition, and the margin of the partition located on the outside of one end of the raw rubber sheet is greater than the margin located on the outside of the other end of the raw rubber sheet.

[0025] In some specific embodiments, stacking the raw material pile further comprises:

[0026] The same corner of each partition is set as a missing corner structure; the partitions are located in the same orientation as the missing corner structure and are stacked alternately with the raw film.

[0027] In some specific embodiments, the notched corner structure is provided by cutting corners along a straight line.

[0028] In some specific embodiments, stacking the raw material pile further includes: arranging the notched structure at the end of the partition with a smaller residual amount of the raw rubber sheet.

[0029] In some specific embodiments, when flipping the partition, the end of the partition with a larger margin relative to the raw film is grasped and flipped 180° toward the other end.

[0030] Compared with the prior art, the advantages and positive effects of the present invention are as follows: since the contact and connection area between the first side of the partition with greater roughness and the raw rubber sheet is greater than the contact and connection area between the second side of the partition with less roughness and the raw rubber sheet, the connection between the raw rubber sheet in the raw material pile and the first side of the partition is tighter than the connection between the second side and the raw rubber sheet, making it more difficult for the raw rubber sheet to separate from the first side; while the second side is relatively easier to separate from the raw rubber sheet. The raw rubber sheet stripping method of the present invention places the raw material pile with the first side of the partition with greater roughness facing upward, so that when the partition on the raw material pile is flipped from one end to the other during the raw rubber sheet stripping process, it is easier to separate from the raw rubber sheet on the lower side thereof, and the raw rubber sheet on the upper side thereof is flipped from its upper side to its lower side without falling, thereby improving the reliability of the raw rubber sheet stripping process and improving production efficiency.

[0042] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0043] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 The raw film stripping method of the present invention comprises:

[0044] S1, placing at least one raw material pile with the first side 12 of the partition 1 facing upward;

[0045] S2, flipping the partition 1 on the top layer of the raw material pile to separate it from the adjacent raw film 2 located below it;

[0046] S3. Repeatedly flip the partition 1 located at the top of the raw material pile to separate it from the adjacent raw film 2 located below it; at the same time, place the raw film 2 adhered to the upper side of the partition 1 downward.

[0047] The raw material pile includes a plurality of partitions 1 and a plurality of raw films 2, and the partitions 1 and the raw films 2 are stacked in an alternating manner; the partitions 1 are located at the top and bottom of the raw material pile, so as to isolate the raw material pile from the surrounding objects and protect the raw films 2 during transportation and / or handling;

[0048] The separator 1 is a flexible flat plate structure, including a first side surface 12 and a second side surface 13; the roughness of the first side surface 12 is different from that of the second side surface 13, and the roughness of the first side surface 12 is greater than that of the second side surface 13;

[0049] S2 flips over the partition 1 at the top of the raw material pile. The partition 1 is the partition 1 at the top of the raw material pile in the initial operation. That is, the partition 1 above the raw material pile is used to isolate the environment during transportation and / or handling;

[0050] S3 repeatedly flips over the partition 1 located at the top of the raw material pile, and the partition 1 is located below the uppermost partition 1 and has the raw film 2 adhered to its upper side.

[0051] In the solution of the present invention, because the contact and connection area between the first side surface 12 of the separator 1 with greater roughness and the raw rubber sheet 2 is greater than the contact and connection area between the second side surface 13 of the separator 1 with less roughness and the raw rubber sheet 2, the raw rubber sheet 2 in the raw material pile is more tightly connected to the first side surface 12 of the separator 1 than to the second side surface 13, making it more difficult for the raw rubber sheet 2 to separate from the first side surface 12; while the second side surface 13 is relatively easier to separate from the raw rubber sheet 2. The raw rubber sheet stripping method of the present invention places the raw material pile with the first side surface 12 of the separator 1 with greater roughness facing upward. This allows the separator 1 on the raw material pile to be more easily separated from the raw rubber sheet 2 below it when it is flipped from one end to the other during the raw rubber sheet stripping process, and the raw rubber sheet 2 above it is less likely to fall off when it is flipped from its upper side to its lower side, thereby improving the reliability of the raw rubber sheet stripping process and increasing production efficiency.

[0052] When multiple raw material piles are placed, the raw material piles are placed adjacent to each other, so that the partitions 1 of the raw material piles can be turned over at the same time and placed at the same time.

[0053] The specific content and principle of the raw film stripping method of the present invention are described in detail below through specific embodiments.

[0054] In a specific embodiment, referring to Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 In the raw film stripping method, turning over the partition 1 on the raw film 2 placement table to separate it from the raw film 2 below it includes:

[0055] S3, placing the separator 1 with the raw film 2 attached thereto together with the raw film 2 on the raw film placement table 3 with the raw film 2 facing downward;

[0056] S41, the raw film placement table 3 absorbs the raw film 2 located on its upper side;

[0057] S42, flip the partition 1 on the top layer of the raw film placement table 3 to separate it from the raw film 2 located below it; and the separated raw film 2 remains on the raw film placement table 3, completing the separation of the partition 1 and the raw film 2.

[0058] Among them, the raw film placement table 3 can adsorb the raw film 2 located on its upper side through an adsorption device 5 arranged on the raw film placement table 3; for example, the adsorption device 5 includes at least one vacuum suction nozzle and an exhaust fan connected to the vacuum suction nozzle.

[0059] The raw film stripping method of this embodiment uses the raw film placement table 3 to absorb the raw film 2 located on its upper side to ensure that the top partition 1 is separated from the raw film 2 located on its lower side when it is flipped from one end to the other end, thereby improving the reliability of separation between the partition 1 and the raw film 2.

[0060] Of course, the raw film placement table 3 can place multiple partitions 1 with raw films 2 side by side, and at the same time flip the partitions 1 on the raw film placement table 3 to separate the multiple raw films 2 from the corresponding partitions 1.

[0061] In a specific embodiment, referring to Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 The method for stripping the raw film further includes: turning over the partition plate 1 on the raw film placement table 3 to separate the raw film 2 therefrom;

[0062] S43. After the raw film 2 is separated from the partition 1, the raw film placement table 3 removes the adsorption of the raw film 2 thereon.

[0063] In a specific embodiment, referring to Figure 2 、 Figure 3 、 Figure 5 、 Figure 8 The method for stripping the raw film further includes: turning over the partition plate 1 on the raw film placement table 3 to separate the raw film 2 therefrom;

[0064] S3, placing the separator 1 with the raw film 2 attached thereto together with the raw film 2 on the raw film placement table 3 with the raw film 2 facing downward;

[0065] S42, the raw film placement table 3 presses one end of the raw film 2 located on its upper side;

[0066] S43, flip the partition 1 on the top layer of the raw film placement table 3 to separate it from the raw film 2 located below it; and the separated raw film 2 remains on the raw film placement table 3, completing the separation of the partition 1 and the raw film 2.

[0067] The raw film placement table 3 can press one end of the raw film 2 located on the upper side thereof by a pressing plate device 4 provided on the raw film placement table 3. For example, the pressing plate device 4 includes at least one pressing plate 41 and a lifting drive device 42 connected to the pressing plate 41.

[0068] The pressing plate 41 is arranged above one end of the raw film placement table 3; when the raw film 2 is placed on the raw film placement table 3, it is located above one end of the raw film 2;

[0069] To separate the separator 1 from the film stock 2 on the film stock placement table 3, the process begins with S41: grabbing one end of the separator 1 below the pressure plate 41 and flipping it so that the end of the film stock 2 is exposed directly below the pressure plate 41. At this point, the flipping is stopped, and S42, the pressure plate 41 is driven downward by the film stock driving device to press on the end of the film stock 2. S43, the flipping of the partially flipped separator 1 is continued to completely separate it from the film stock 2 below. The film stock 2 separated from the separator 1 remains on the film stock placement table 3, completing the separation of the film stock 2 from the separator 1.

[0070] The raw film stripping method of this embodiment uses the raw film placement table 3 pressure plate device 4 to press one end of the raw film 2 located on the upper side thereof to ensure that the upper layer partition 1 on the raw film placement table 3 is separated from the raw film 2 located on the lower side thereof when it is flipped from one end to the other end, thereby improving the reliability of the separation of the partition 1 and the raw film 2.

[0071] Of course, the raw film placement table 3 can place multiple partitions 1 with raw films 2 side by side, and at the same time flip the partitions 1 on the raw film placement table 3 to separate the multiple raw films 2 from the corresponding partitions 1.

[0072] In a specific embodiment, referring to Figure 2 、 Figure 3 、 Figure 5 、 Figure 8 The method for stripping the raw film further includes: turning over the partition plate 1 on the raw film placement table 3 to separate the raw film 2 therefrom;

[0073] S44. After the raw film 2 is separated from the partition 1, the raw film placement table 3 is removed from pressing one end of the raw film 2 thereon.

[0074] In some specific embodiments, referring to Figure 3 The raw film stripping method further includes stacking a raw material pile S0, which includes:

[0075] The first side surfaces 12 of the partitions 1 in the raw material pile are oriented in the same direction, that is, the first side surfaces 12 of the partitions 1 are all facing upward or downward; correspondingly, the second side surfaces 13 of the partitions 1 are all facing downward or upward.

[0076] In some specific embodiments, referring to Figure 6 、 Figure 7 The raw material pile S0 further includes:

[0077] S01, setting a corner of the partition 1 in the same direction as the corner structure 11;

[0078] S02. Stack the partitions 1 with the raw film 2 in an staggered manner so that the notched corner structures 11 thereof are located in the same orientation.

[0079] The raw film stripping method of this embodiment reduces the stacking errors in the side direction of the partition 1 and improves the accuracy and efficiency of the raw material stacking.

[0080] In some specific embodiments, the notched corner structure 11 is achieved by cutting corners along a straight line.

[0081] In some specific embodiments, referring to Figure 3 、 Figure 7 The stacked green film S0 further comprises:

[0082] The raw film 2 is rectangular; the partition 1 is a rectangle whose length is greater than that of the raw film 2; the raw film 2 and the partition 1 are stacked correspondingly in length, and the margin of the partition 1 on the outside of one end of the raw film 2 is greater than the margin on the outside of the other end of the raw film 2.

[0083] The raw film stripping method of this embodiment increases the margin of the outer partition 1 at one end of the raw film 2 so that this end of the partition 1 can be grasped when the partition 1 is turned over, making grasping more convenient and reliable.

[0084] In some specific embodiments, referring to Figure 8 The stacking of raw materials also includes: arranging the notched structure 11 at the end of the partition 1 with a smaller outer margin relative to one end of the raw film 2.

[0085] In some specific embodiments, referring to 8, when flipping the partition 1 on the raw material pile and / or flipping the partition 1 on the raw material placement table 3, grab the end of the partition 1 with a larger outer margin extending beyond one end of the raw film 2 and flip it 180° toward the other end.
