Description

Technical Field

[0001] This invention relates to the field of facial mask production technology, and in particular to an immersion device for facial mask production. Background Technology

[0002] Facial masks are a type of carrier for beauty and skincare products. Currently, facial masks made of powder, kaolin, non-woven fabric, silk, tencel, bio-cellulose, and non-woven fabric are widely used.

[0003] During the production process of face masks, the mask needs to be packaged in a bag before the mask liquid is added. This results in some parts of the mask being folded so that the mask liquid cannot be soaked in, causing the mask liquid to not be evenly distributed on the mask. Furthermore, the amount of mask liquid absorbed by the mask is less than intended, failing to provide the moisturizing effect of the mask bag and thus reducing the quality of the mask.

[0004] CN216378712U discloses a mask soaking device for mask production. This device sprays mask liquid to ensure that the mask liquid can be evenly absorbed. The sprayed mask liquid is collected in a soaking box and then soaked in a placement tank to allow the mask to absorb more mask liquid. This prevents the mask from having too little mask liquid after packaging, which would not provide the moisturizing effect of the mask bag.

[0005] However, in actual use, it was found that the mask soaking device used in mask production uses a spraying method to soak the mask. Due to the existence of the perforated parts of the mask, it cannot guarantee uniform spraying, and it often requires manual placement and removal, which is complicated to operate. Summary of the Invention

[0006] Therefore, it is necessary to provide a new type of mask production soaking device to address the problems of uneven spraying and complex operation of current mask production soaking devices.

[0007] The above objectives are achieved through the following technical solutions:

[0008] An immersion apparatus for producing face masks, the immersion apparatus for producing face masks comprising:

[0009] An immersion tank is provided with a receiving cavity inside, which is filled with a mask liquid of a preset depth during use;

[0010] A conveyor belt assembly is disposed inside the soaking tank. The conveyor belt assembly includes a first conveyor belt and a second conveyor belt. Both the first and second conveyor belts are provided with mesh holes. The first and second conveyor belts form a closed conveying loop inside the soaking tank. The first and second conveyor belts are partially in contact with each other. The contact portion of the first and second conveyor belts is used to transport the face mask through the face mask liquid.

[0011] Furthermore, the portion where the first conveyor belt and the second conveyor belt abut each other includes a first horizontal section, a first vertical section, an annular section, a second vertical section, and a second horizontal section connected sequentially from the inlet end to the outlet end of the mask. The first horizontal section and the second horizontal section are located on the same horizontal line. The first vertical section and the second vertical section abut each other and are located between the first horizontal section and the second horizontal section. The first horizontal section is connected to the first vertical section. The first vertical section is connected to one end of the annular section. The other end of the annular section is connected to the second vertical section. The second vertical section is connected to the second horizontal section. The annular section is immersed in the mask liquid.

[0012] Furthermore, the impregnation device for mask production also includes a pressing cylinder, a first pressing roller, a second pressing roller, a first driving roller, a first follower roller, a second follower roller, a third follower roller, and a fixed roller. The first pressing roller is disposed within the impregnation chamber, and the pressing cylinder is located directly below the first pressing roller and disposed within the impregnation chamber. The second pressing roller is disposed within the impregnation chamber. The first driving roller and the first follower roller are both rotatably disposed within the impregnation chamber and located on either side of the first pressing roller. The second follower roller and the third follower roller are both rotatably disposed within the impregnation chamber. The first conveyor belt is placed inside the immersion tank and is located between the pressing cylinder and the first pressing roller. The second follower roller and the third follower roller are arranged opposite to each other. There are multiple fixed rollers, and all of the fixed rollers are arranged inside the immersion tank. The first conveyor belt passes around the first pressing roller, the first drive roller, the first follower roller, the second follower roller, the third follower roller and the pressing cylinder to form a conveying loop. The second conveyor belt passes around the fixed roller, the second follower roller, the third follower roller, the pressing cylinder and the second pressing roller to form a conveying loop.

[0013] Furthermore, the immersion device for mask production also includes a first driving member, which provides driving force for the rotation of the first driving roller and the second follower roller, wherein the first driving roller and the second follower roller rotate in opposite directions.

[0014] Furthermore, the first pressing roller is rotatably and slidably disposed in the impregnation tank in a vertical direction, and the first pressing roller is used to tension the first conveyor belt; the pressing cylinder is rotatably and slidably disposed in the impregnation tank in a vertical direction, and the second pressing roller is rotatably and slidably disposed in the impregnation tank in a horizontal direction, and the pressing cylinder and the second pressing roller cooperate to tension the second conveyor belt; the impregnation device for mask production also includes a second driving member, which is used to provide driving force for the rotation of the third follower roller; the mask is spaced between the abutting portions of the first conveyor belt and the second conveyor belt.

[0015] Furthermore, the pressing cylinder, the first pressing roller, and the second pressing roller move at the same speed, and the moving speed of the pressing cylinder is positively correlated with the conveying speed of the first conveyor belt.

[0016] Furthermore, the diameter of the mesh openings on the first conveyor belt is larger than the diameter of the mesh openings on the second conveyor belt, and the mesh openings on the second conveyor belt can only allow materials of a preset size to pass through.

[0017] Furthermore, the abutting portions of the first and second conveyor belts surround the receiving cavity to form a first liquid cavity, and the second conveyor belt divides the receiving cavity into a second liquid cavity and a third liquid cavity; the immersion tank is provided with a first one-way pipe and a second one-way pipe, one end of the first one-way pipe is connected to the first liquid cavity and the other end is connected to the third liquid cavity, and the flow direction of the first one-way pipe is from the third liquid cavity to the first liquid cavity; one end of the second one-way pipe is connected to the first liquid cavity and the other end is connected to the second liquid cavity, and the flow direction of the second one-way pipe is from the first liquid cavity to the second liquid cavity.

[0018] Furthermore, a scraper is provided inside the soaking tank to scrape the mask off the second conveyor belt.

[0019] Furthermore, an observation window is provided on the side wall of the immersion chamber.

[0020] The beneficial effects of this invention are:

[0021] This invention provides an immersion device for facial mask production, comprising an immersion tank and a conveyor belt assembly. The conveyor belt assembly is disposed inside the immersion tank and includes a first conveyor belt and a second conveyor belt. Both the first and second conveyor belts have mesh openings and form a closed transport loop inside the immersion tank. The first and second conveyor belts partially abut each other, and this abutting portion is used to transport the facial mask through the mask liquid. By providing a first and second conveyor belt with a closed transport loop inside the immersion tank, during use, the facial mask is held between the first and second conveyor belts and immersed in the mask liquid within the immersion tank as the first and second conveyor belts move, thereby ensuring uniform immersion of the facial mask.

[0022] Furthermore, by setting the contact portion of the first conveyor belt and the second conveyor belt to include a first horizontal section, a second horizontal section, a first vertical section, a second vertical section, and a ring section, the dry mask and the wet mask can come into contact, so that the wet mask is not over-soaked and the dry mask is pre-soaked, thereby improving the adhesion of the mask liquid to the dry mask.

[0023] Furthermore, by setting the diameter of the mesh on the first conveyor belt to be larger than the diameter of the mesh on the second conveyor belt, and ensuring that the mesh on the second conveyor belt can only allow substances of a preset size to pass through, debris and impurities can only float in the mask liquid between the second conveyor belts, thus preventing debris and impurities from contaminating the mask liquid.

[0024] Furthermore, by setting the abutting portion of the first and second conveyor belts to surround and form a first liquid chamber within the receiving cavity, the second conveyor belt divides the receiving cavity into a second liquid chamber and a third liquid chamber. The soaking tank is equipped with a first one-way tube and a second one-way tube. One end of the first one-way tube is connected to the first liquid chamber, and the other end is connected to the third liquid chamber. One end of the second one-way tube is connected to the first liquid chamber, and the other end is connected to the second liquid chamber. During use, the pressing cylinder moves up and down vertically, causing the volume of the first liquid chamber to periodically increase and decrease. This allows the debris attached to the mask to float only in the second liquid chamber, ensuring that the mask liquid in the first liquid chamber can be replenished in a timely manner and guaranteeing the cleanliness of the mask soaking.

[0025] Furthermore, by installing a scraper inside the soaking tank, the mask can be scraped off the second conveyor belt, facilitating subsequent processing.

[0026] Furthermore, by setting an observation window on the side wall of the soaking tank, the level of the mask liquid in the soaking tank can be monitored in real time, and the mask liquid can be replenished in time to avoid incomplete soaking of the mask due to insufficient mask liquid in the soaking tank.

[0043] like Figures 1 to 8 As shown, an embodiment of the present invention provides an immersion device for mask production, used to immerse a mask. In this embodiment, the immersion device includes an immersion tank 100 and a conveyor belt assembly. The immersion tank 100 has a top opening and a receiving cavity 140 is provided inside the immersion tank 100. The receiving cavity 140 is filled with a mask liquid of a preset depth. The conveyor belt assembly is disposed inside the immersion tank 100 and includes a first conveyor belt 410 and a second conveyor belt 420. Both the first conveyor belt 410 and the second conveyor belt 420 are provided with mesh holes. The first conveyor belt 410 and the second conveyor belt 420 form a closed conveying loop inside the immersion tank 100. Both the first conveyor belt 410 and the second conveyor belt 420 are partially immersed in the mask liquid. The first conveyor belt 410 and the second conveyor belt 420 are partially in contact. The part of the first conveyor belt 410 and the second conveyor belt 420 in contact is used to transport the mask and pass through the mask liquid.

[0044] To improve the automation level of the saturation device in mask production, the conveyor belt assembly can be configured to also include a feeding belt 400 and a discharging belt 430. Both the feeding belt 400 and the discharging belt 430 are located above the surface of the mask liquid. The feeding belt 400 and the discharging belt 430 are arranged on both sides of the first conveyor belt 410. The feeding belt 400 is used to transport the cut dry mask to the second conveyor belt 420, and the discharging belt 430 is used to receive the mask after it has been saturated with mask liquid from the second conveyor belt 420 and transport it to a designated area.

[0045] In use, the cut dry face mask is continuously placed on the feeding belt 400 and transported to the second conveyor belt 420 by the feeding belt 400. Then, the dry face mask is held between the first conveyor belt 410 and the second conveyor belt 420, and is soaked in the face mask liquid in the soaking tank 100 as the first conveyor belt 410 and the second conveyor belt 420 move, so that the face mask is completely soaked. Then, the face mask moves from the second conveyor belt 420 to the discharge belt 430, and is moved to the set area by the discharge belt 430, so as to facilitate the next process.

[0046] In some embodiments, such as Figure 5 As shown, the part where the first conveyor belt 410 and the second conveyor belt 420 abut together includes a first horizontal section, a first vertical section, an annular section, a second vertical section, and a second horizontal section connected sequentially from the inlet end to the outlet end of the mask. The first horizontal section and the second horizontal section are located on the same horizontal line. The first vertical section and the second vertical section abut together and are located between the first horizontal section and the second horizontal section. The first horizontal section is connected to the first vertical section. The first vertical section is connected to one end of the annular section. The other end of the annular section is connected to the second vertical section. The second vertical section is connected to the second horizontal section. The annular section is immersed in the mask liquid.

[0047] When using, such as Figure 5 As shown, the cut dry face mask is continuously and without interval placed on the feeding belt 400 and transported to the second conveyor belt 420 under the drive of the feeding belt 400. Then the dry face mask is clamped between the first conveyor belt 410 and the second conveyor belt 420 and moves synchronously with the first conveyor belt 410 and the second conveyor belt 420. After the dry face mask passes through the first horizontal section, the first vertical section and the circular section, it is soaked in face mask liquid to become a wet face mask. After the wet face mask passes through the second vertical section and the second horizontal section, it moves to the discharge belt 430 and moves to the set area under the drive of the discharge belt 430 to facilitate the next process.

[0048] During the movement of the mask, the dry and wet masks come into contact at the first and second vertical sections, preventing the wet mask from becoming overly wet and pre-wetting the dry mask, thus improving the adhesion of the mask liquid to the dry mask. This process is repeated so that the wet mask can continuously come into contact with the dry mask, thereby pre-wetting the dry mask with the wet mask.

[0049] In a further embodiment, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the immersion device for mask production also includes a first pressing roller 260, a pressing cylinder 250, a second pressing roller 270, and a connecting assembly 200. The connecting assembly 200 includes a first driving roller 210, a first follower roller 211, a second follower roller 220, a third follower roller 230, and a fixed roller 240. The first pressing roller 260 is positioned above the surface of the mask liquid and is located inside the immersion tank 100. The pressing cylinder 250 is positioned below the surface of the mask liquid, providing pressure. The cylinder 250 is disposed inside the immersion tank 100, and the pressing cylinder 250 is located directly below the first pressing roller 260. The second pressing roller 270 is disposed above the liquid surface, and is located inside the immersion tank 100 between the pressing cylinder 250 and the first pressing roller 260. The first driving roller 210 and the first follower roller 211 are both disposed above the liquid surface of the mask liquid, and are rotatably disposed inside the immersion tank 100 and located below the first pressing roller 260. The clamping roller 260 has two sides; there are two second follower rollers 220 and two third follower rollers 230. Both the two second follower rollers 220 and the two third follower rollers 230 are rotatably arranged within the immersion tank 100 and are located between the clamping cylinder 250 and the first clamping roller 260. The two second follower rollers 220 and the two third follower rollers 230 are arranged vertically, corresponding one-to-one and relatively close to each other. The number of fixed rollers 240 is multiple, and multiple fixed rollers 240 are arranged in the immersion tank 100; the first conveyor belt 410 passes around the first pressing roller 260, the first drive roller 210, the first follower roller 211, the second follower roller 220, the third follower roller 230 and the pressing cylinder 250 to form a conveying loop; the second conveyor belt 420 passes around the fixed roller 240, the second follower roller 220, the third follower roller 230, the pressing cylinder 250 and the second pressing roller 270 to form a conveying loop.

[0050] It is understood that the portion of the first conveyor belt 410 and the second conveyor belt 420 that abuts between the first drive roller 210 and the second follower roller 220 is the first horizontal section; the portion of the first conveyor belt 410 and the second conveyor belt 420 that abuts between the two second follower rollers 220 is the first vertical section; the portion of the first conveyor belt 410 and the second conveyor belt 420 that abuts between the two third follower rollers 230 is the second vertical section; the portion of the first conveyor belt 410 and the second conveyor belt 420 that abuts around the outside of the pressing cylinder 250 is an annular section; and the portion of the first conveyor belt 410 and the second conveyor belt 420 that abuts between the third follower roller 230 and the first follower roller 211 is the second horizontal section.

[0051] In a further embodiment, such as Figure 1 and Figure 2 As shown, the immersion device for mask production also includes a drive assembly 300, which further includes a first drive member. The first drive member is used to provide driving force for the rotation of the first drive roller 210 and the second follower roller 220. In this embodiment, the first drive member is a first drive motor 310. The first drive motor 310 is fixedly connected to the side wall of the immersion tank 100 by bolts. A first drive wheel 311 is fixedly sleeved on the motor shaft of the first drive motor 310. A first gear is provided on the first drive wheel 311, and a second gear is provided on the third follower roller 230. The first gear and the second gear mesh. In use, the first drive motor 310 drives the third follower roller 230 to rotate through gear engagement, and drives the second conveyor belt 420 on the right side of the pressing cylinder 250 to rotate through the third follower roller 230, so that the first drive roller 210 and the second follower roller 220 rotate in opposite directions.

[0052] In a further embodiment, such as Figure 4 and Figure 5As shown, a first mounting groove 101, a second mounting groove 102, and a third mounting groove 103 are provided on the side wall of the immersion tank 100. The first mounting groove 101 is arranged vertically and contains a compression spring. The second mounting groove 102 is also arranged vertically and is located directly below the first mounting groove 101. The third mounting groove 103 is arranged horizontally and is located between the first and second mounting grooves 101 and to the right of the first mounting groove 101. A drive cylinder is provided in both the second and third mounting grooves 102 and 103. 150; The first pressing roller 260 is connected to the compression spring via a mounting block. Under the drive of the compression spring, the first pressing roller 260 can slide vertically up and down. The first pressing roller 260 is used to tension the first conveyor belt 410; One end of the pressing cylinder 250 is rotatably connected to the output shaft of the drive cylinder 150 in the second mounting groove 102. Under the drive of the drive cylinder 150 in the second mounting groove 102, the pressing cylinder 250 can slide vertically up and down; One end of the second pressing roller 270 is rotatably connected to the output shaft of the drive cylinder 150 in the third mounting groove 103. The second pressing roller 270 is rotatably connected to the output shaft of the drive cylinder 150 in the third mounting groove 103. Driven by the drive cylinder 150 in the loading slot 103, the second drive assembly 300 can slide left and right in the horizontal direction. The clamping cylinder 250 and the second clamping roller 270 cooperate to tension the second conveyor belt 420. The drive assembly 300 also includes a second drive member, which provides the driving force for the rotation of the third follower roller 230. In this embodiment, the second drive member is a second drive motor 320. The second drive motor 320 is fixedly connected to the side wall of the immersion tank 100 by bolts. A second drive wheel 321 is fixedly sleeved on the motor shaft of the second drive motor 320. The second drive wheel 321 drives the first drive roller 321 through the synchronous belt 322. Roller 210 rotates, a third gear is provided on the second drive wheel 321, and a fourth gear is provided on the second follower roller 220. The third gear and the fourth gear mesh. In use, the second drive motor 320 drives the second follower roller 220 to rotate through the gear engagement, and drives the second conveyor belt 420 on the left side of the pressing cylinder 250 to rotate through the second follower roller 220. On the other hand, it drives the first conveyor belt 410 to rotate through the synchronous belt 322. The masks are transported between the parts where the first conveyor belt 410 and the second conveyor belt 420 abut, and the distance between adjacent masks is the width L of one mask.

[0053] Understandably, the drive cylinder 150 can be any of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0054] When using, such as Figure 5As shown, along the direction perpendicular to the paper (front to back), the mask is positioned on the feeding belt 400, the first conveyor belt 410, the second conveyor belt 420, and the discharge belt 430 such that the mouth cutout of the mask is after the eye cutout, or vice versa. The mask has a width, assuming the width of the mask is L, and the interval between adjacent masks is set to L. The length of the contact portion between the first conveyor belt 410 and the second conveyor belt 420 is set to N times the width of the mask, where N is... Natural numbers; the cut dry face masks are continuously placed on the feeding belt 400 and transported to the second conveyor belt 420 by the feeding belt 400. The dry face masks are then clamped between the first conveyor belt 410 and the second conveyor belt 420, and move synchronously with the first and second conveyor belts 410 and 420. When the wet face mask reaches the horizontal abutment portion of the first and second conveyor belts 410 and 420 on the right side of the axis of the pressing cylinder 250, it is pressed... A dry face mask is placed between the horizontal contact portions of the first conveyor belt 410 and the second conveyor belt 420 on the left side of the axis of the pressing cylinder 250. The second conveyor belt 420 on the left side of the axis of the pressing cylinder 250 rotates forward at a constant speed, causing the dry face mask to move downward. The second conveyor belt 420 on the right side of the axis of the pressing cylinder 250 rotates in the opposite direction at a constant speed, causing the wet face mask to move downward, so that the wet face mask and the dry face mask come into contact, thereby pre-soaking the dry face mask with the wet face mask. This prevents the wet face mask from being over-soaked and improves the adhesion of the face mask liquid to the dry face mask. At the same time, the first pressing roller 260 can slide downward vertically under the action of the compression spring, so that the first conveyor belt 410 is always taut. The pressing cylinder 250 can slide downward vertically under the action of the drive cylinder 150 in the second mounting groove 102. The second pressing roller 270 can slide horizontally to the left under the action of the drive cylinder 150 in the third mounting groove 103, so that the second conveyor belt 420 is always taut.

[0055] After the dry and wet face masks are fully adhered, the second conveyor belt 420 on the left side of the axis of the pressing cylinder 250 rotates forward, causing the pre-soaked dry face mask to continue moving downward. The second conveyor belt 420 on the right side of the axis of the pressing cylinder 250 rotates forward at three times the original speed, causing the wet face mask to move upward by three times L. At the same time, the first pressing roller 260 can slide upward vertically under the action of the compression spring, so that the first conveyor belt 410 is always taut. The pressing cylinder 250 can slide upward vertically under the action of the drive cylinder 150 in the second mounting groove 102. The second pressing roller 270 can slide horizontally to the right under the action of the drive cylinder 150 in the third mounting groove 103, so that the second conveyor belt 420 is always taut. The wet face mask moves onto the discharge belt 430. This process is repeated so that the wet face mask can continuously come into contact with the dry face mask, thereby pre-soaking the dry face mask with the wet face mask.

[0056] In a further embodiment, during the application and separation of the wet and dry face masks, the pressing cylinder 250, the first pressing roller 260, and the second pressing roller 270 move synchronously and at the same speed. The moving speed of the pressing cylinder 250 is positively correlated with the conveying speed of the first conveyor belt 410, so that the first conveyor belt 410 and the second conveyor belt 420 are taut throughout the process.

[0057] In some embodiments, since the mask may have debris and impurities attached during processing, in order to avoid the debris and impurities from contaminating the mask liquid, the diameter of the mesh on the first conveyor belt 410 is set to be larger than the diameter of the mesh on the second conveyor belt 420. The mesh on the second conveyor belt 420 can only allow substances of a preset size to pass through, so that the debris and impurities can only float in the mask liquid between the second conveyor belts 420, thus avoiding the debris and impurities from contaminating the mask liquid.

[0058] In a further embodiment, such as Figure 5 and Figure 7As shown, the abutting portions of the first conveyor belt 410 and the second conveyor belt 420 surround and form the first liquid chamber 141. The second conveyor belt 420 divides the impregnation tank 100 into a second liquid chamber 142 and a third liquid chamber 143. A first one-way pipe 110 and a second one-way pipe 120 are provided on the impregnation tank 100. One end of the first one-way pipe 110 is connected to the first liquid chamber 141, and the other end is connected to the third liquid chamber 143. The flow direction of the first one-way pipe 110 is from the third liquid chamber 143 to the first liquid chamber 142. 1; One end of the second one-way tube 120 is connected to the first liquid chamber 141, and the other end is connected to the second liquid chamber 142. The flow direction of the second one-way tube 120 is from the first liquid chamber 141 to the second liquid chamber 142. In use, the pressing cylinder 250 moves up and down vertically, causing the volume of the first liquid chamber 141 to periodically increase and decrease. When the volume of the first liquid chamber 141 increases, under the action of the internal and external pressure difference, the mask liquid in the third liquid chamber 143 enters the first liquid chamber through the first one-way tube 110. In step 141, on the other hand, the mask liquid enters the second liquid chamber 142 through the mesh on the second conveyor belt 420. The mask liquid in the second liquid chamber 142 enters the first liquid chamber 141 through the mesh on the second conveyor belt 420 and the mesh on the first conveyor belt 410. When the volume of the first liquid chamber 141 decreases, the mask liquid in the first liquid chamber 141 enters the second liquid chamber 142 through the mesh on the first conveyor belt 410, the mesh on the second conveyor belt 420, and the second one-way tube 120. Meanwhile, debris and impurities in the first liquid chamber 141 enter the second liquid chamber 142 through the second one-way tube 120. The mask liquid in the second liquid chamber 142 enters the third liquid chamber 143 through the mesh on the second conveyor belt 420. Since the mesh on the second conveyor belt 420 can only allow substances of a preset size to pass through, the debris and impurities attached to the mask can only float in the second liquid chamber 142, so that the mask liquid in the first liquid chamber 141 can be renewed in time, ensuring the cleanliness of the mask soaking.

[0059] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, a scraper 130 is provided inside the soaking tank 100. The scraper 130 is located between the second conveyor belt 420 and the discharge belt 430. The scraper 130 is used to scrape the mask off the second conveyor belt 420 for subsequent processing.

[0060] In some embodiments, an observation window is provided on the side wall of the soaking tank 100. The height of the mask liquid in the soaking tank 100 can be monitored in real time through the observation window, and the mask liquid can be replenished in the soaking tank 100 in a timely manner to avoid incomplete soaking of the mask due to lack of mask liquid in the soaking tank 100.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
