Description

Technical Field

[0001] This disclosure relates to the fields of semiconductor and photovoltaic technology, and in particular to a sheet stop mechanism and a sheet loading and unloading system. Background Technology

[0002] With the development of photovoltaic technology, solar cells are widely used in various fields. During the processing of solar cells, the finished cells need to be conveyed into baskets by a conveyor mechanism when unloading. When the cells are conveyed to their last position, positioning errors can easily occur, causing the edges of the silicon wafers into the basket to collide with the bottom rod of the basket, resulting in chipped or even broken cells. These chips are difficult to clean manually and seriously affect working hours and production capacity. Utility Model Content

[0003] In view of this, the present disclosure provides a sheet stop mechanism and a sheet loading and unloading system to solve the problem that after the battery cells are processed, they are prone to chipping or even breaking when they are transported to the basket in the related art.

[0004] In a first aspect, one embodiment of this disclosure provides a sheet stop mechanism configured to stop a sheet being conveyed from the conveying end of a sheet conveying mechanism to a carrying mechanism. The sheet stop mechanism includes: a connecting bracket connected to the side of the sheet conveying mechanism near the conveying end; one or more stop members connected to the connecting bracket, the stop members being arranged at intervals from the conveying end in the conveying direction of the sheet conveying mechanism, and the stop members being flexible members. When the sheet conveying mechanism conveys the sheet from the conveying end to the carrying mechanism, the sheet moves to a stop and stops after contacting the stop member, so that the sheet is unloaded into the carrying mechanism.

[0005] In some embodiments, the carrying mechanism includes a plurality of base rods, each base rod having a plurality of vertically arranged toothed grooves, the openings of which face the conveying end of the sheet conveying mechanism. Each toothed groove includes a tooth base and a tooth tip. When a stop member extends into the carrying mechanism, a stop member is located between two adjacent base rods. When the sheet moves to the point of contact with the stop member, the stop member is located at a preset position. The preset position is any position in the conveying direction between the tooth base and the tooth tip.

[0006] In some embodiments, when the sheet conveying mechanism conveys the sheet from the conveying end to the carrying mechanism, along the conveying direction, the preset position has a first distance from the tooth root, and the ratio of the first distance to the distance from the tooth root to the tooth tip is in the range of 1 / 3 to 2 / 3.

[0007] In some embodiments, the sheet stop mechanism includes two or more stop members spaced apart along a first direction, the first direction being perpendicular to the conveying direction in a horizontal plane. The connecting bracket includes: a connecting portion extending along the first direction, the connecting portion being detachably connected to the sheet conveying mechanism; and two or more mounting portions connected to the side of the connecting portion away from the sheet conveying mechanism, each mounting portion being connected to a stop member.

[0008] In some embodiments, the connecting portion is connected to the side of the sheet conveying mechanism away from the conveyed sheet, and the mounting portion includes: a first connecting section extending along the conveying direction, one end of the first connecting section being connected to the connecting portion; a second connecting section extending in a vertical direction, one end of the second connecting section being connected to the other end of the first connecting section, and the other end of the second connecting section being connected to a stop member facing one side of the sheet conveying mechanism, the two ends of the stop member in the vertical direction being located on both sides of the sheet conveyed by the sheet conveying mechanism.

[0009] In some embodiments, the stop is detachably connected to the connecting bracket.

[0010] In some embodiments, the stop is made of polyoxymethylene or polyurethane.

[0011] In some embodiments, the distance from the stop member to the conveying end of the sheet conveying mechanism is adjustable. The sheet stop mechanism further includes a drive member connected to the sheet conveying mechanism and connected to the connecting bracket. The drive member is configured to drive the connecting bracket to move along the conveying direction of the sheet conveying mechanism to adjust the distance from the stop member to the conveying end.

[0012] Secondly, embodiments of this disclosure also provide a sheet material loading and unloading system, including: a sheet material conveying mechanism configured to convey a sheet material along a conveying direction, the sheet material conveying mechanism having a conveying end; a bearing mechanism disposed along the conveying direction on the side of the sheet material conveying mechanism facing the conveying end, the bearing mechanism being configured to bear the sheet material conveyed from the conveying end; and the sheet material stop mechanism described above, the sheet material stop mechanism being connected to the sheet material conveying mechanism, the sheet material stop mechanism being configured to stop the sheet material conveyed from the conveying end of the sheet material conveying mechanism to the bearing mechanism.

[0013] In some embodiments, the sheet conveying mechanism includes: a first conveying component configured to convey a sheet; a second conveying component disposed on one side of the first conveying component, the second conveying component conveying the sheet from the first conveying component, the conveying end being located at the end of the second conveying component away from the first conveying component, a sheet stop mechanism disposed on the second conveying component, the second conveying component being extendable along the conveying direction to drive the sheet at the conveying end into the carrying mechanism, and the sheet stop mechanism being able to stop the sheet extending into the carrying mechanism.

[0014] This disclosure provides a sheet stop mechanism and a sheet loading / unloading system. By setting the sheet stop mechanism on the sheet conveying mechanism, the stop member in the sheet stop mechanism is set as a flexible member and is set in a preset position. When the sheet conveying mechanism conveys the sheet from the conveying end to the carrying mechanism, the stop member will abut against the sheet before the edge of the sheet collides with the carrying mechanism and stop the sheet from moving. The stop member provides a buffer for the stop of the sheet being guided to the carrying mechanism, avoiding hard collision between the sheet and the carrying mechanism, thereby avoiding the sheet from breaking or fragmenting.

[0025] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0026] Figure 1 The diagram shown is a schematic diagram of a sheet loading and unloading system provided in an embodiment of this disclosure. Figure 2 The diagram shown is a schematic diagram of the cooperation between a sheet stop mechanism and a sheet conveying mechanism provided in an embodiment of this disclosure. Figure 3 for Figure 2 The diagram shows a partial enlarged view of part A in the cooperation between the sheet stop mechanism and the sheet conveying mechanism. Arrow X points to the conveying direction X of the sheet conveying mechanism 2. This conveying direction X can be a straight line in the horizontal plane and can be adaptively adjusted according to the input and output positions of the conveyed sheet; it is not specifically limited. Arrow Y points to the vertical direction Y, which is perpendicular to the conveying direction X, and will not be emphasized separately thereafter.

[0027] This disclosure provides a sheet material stop mechanism, such as... Figures 1 to 3The sheet stop mechanism 1 is configured to stop the sheet material being conveyed from the conveying end 221 of the sheet conveying mechanism 2 to the carrying mechanism 3. Specifically, the sheet stop mechanism 1 includes a connecting bracket 11 and one or more stop members 12. The connecting bracket 11 is connected to the side of the sheet conveying mechanism 2 near the conveying end 221, and the stop members 12 are connected to the connecting bracket 11. The stop members 12 are arranged at intervals from the conveying end 221 in the conveying direction X of the sheet conveying mechanism 2, and the stop members 12 are flexible. When the sheet conveying mechanism 2 conveys the sheet material from the conveying end 221 to the carrying mechanism 3, the sheet material moves to a stop and stops after contacting the stop member 12, so that the sheet material is unloaded into the carrying mechanism 3.

[0028] Optionally, the sheet material can be, for example, silicon wafers or silicon carbide wafers used to make solar cells, without specific limitations. For ease of description, it will be referred to as "silicon wafer" from now on.

[0029] Optionally, the carrying mechanism 3 can be, for example, a basket for carrying multiple silicon wafers 4 after processing, and the wafer conveying mechanism 2 is used to convey the processed silicon wafers 4 and unload them into the basket. The wafer conveying mechanism 2 may include a first conveying component 21 and a second conveying component 22, with the first conveying component 21 located on one side of the second conveying component 22 and the conveying end 221 located at the end of the second conveying component 22 away from the first conveying component 21. The wafer conveying mechanism 2 may also include a conveyor belt assembly 24. The first conveying component 21 and the second conveying component 22 may share a single conveyor belt assembly 24, or they may be provided as independent conveyor belt assemblies, allowing the processed silicon wafers 4 to move along the conveying direction X from the unloading position to the basket position under the drive of the conveyor belt assembly 24. In addition, the second conveying assembly 22 is configured to extend and retract along the conveying direction X. When a silicon wafer 4 moves to a position close to the conveying end 221, the second conveying assembly 22 can extend so that the conveying end 221 and the silicon wafer 4 on its position enter the receiving space of the basket along the conveying direction X, thereby guiding the silicon wafer 4 into the basket.

[0030] It should be emphasized that in this embodiment, the first conveying component 21 and the second conveying component 22 share a conveyor belt assembly 24. The sheet conveying mechanism 2 may also include a belt adjustment component 23, which is configured to adaptively adjust the conveyor belt in the conveyor belt assembly 24 as the second conveying component 22 extends and retracts, so that the conveyor belt can always be kept in a taut state, thereby ensuring that the conveyor belt is not affected by the extension and retraction of the second conveying component 22 and can always be kept in a taut state for conveying the silicon wafer 4. The specific mechanism of the sheet conveying mechanism 2 will not be described in detail here.

[0031] It is understood that the wafer insertion port of the wafer basket faces the conveying end 221 of the sheet conveying mechanism 2. The wafer basket has multiple insertion positions in the vertical direction Y. During the process of inserting wafers into the wafer basket by the sheet conveying mechanism 2, each time the sheet conveying mechanism 2 completes an extension, the wafer basket will move upwards along the vertical direction Y by the distance of one insertion position. The sheet conveying mechanism 2 can drive the sheet stop mechanism 1 to retract to its initial position. This operation is repeated multiple times so that multiple silicon wafers 4 are inserted into different insertion positions in the wafer basket. The specific cooperation method and working process of the wafer basket and the sheet conveying mechanism 2 are not described in detail.

[0032] Optionally, the flower basket may include, for example, a plurality of bottom rods 31 and a plurality of top rods 32 enclosing a receiving space for accommodating silicon wafers 4. Both the bottom rods 31 and top rods 32 extend in the vertical direction Y. Adjacent top rods 32 enclose an insertion port 3a. The bottom rods 31 are positioned opposite to the insertion port 3a. The conveying end 221 of the sheet conveying mechanism 2 can extend into the receiving space from the insertion port 3a to convey the silicon wafers 4 from the sheet conveying mechanism 2 into the flower basket. Specifically, at least one of the bottom rods 31 has a plurality of grooves 311 arranged in the vertical direction Y on the side facing the insertion port 3a. Each groove 311 forms an insertion position. The sheet conveying mechanism 2 can insert the silicon wafers 4 conveyed to the conveying end 221 from the insertion port 3a into the grooves 311 of the flower basket by telescoping. The specific structure of the flower basket is not described in detail.

[0033] In this embodiment, a sheet stop mechanism 1 is provided on the sheet conveying mechanism 2. The stop member 12 in the sheet stop mechanism 1 is set as a flexible member and is set in a preset position so that the sheet conveying mechanism 2 extends to convey the silicon wafer 4 from the conveying end 221 into the basket. Before the edge of the silicon wafer 4 enters the insertion position of the bottom rod 31 of the basket and contacts the bottom rod 31, the silicon wafer 4 will first abut against the stop member 12. The flexible stop member 12 can generate a slight deformation when it contacts the edge of the silicon wafer 4, thereby providing a buffer for the silicon wafer 4 to stop, avoiding hard collision when the silicon wafer 4 stops, and thus avoiding the situation of the silicon wafer 4 breaking or fragmenting.

[0034] Optionally, the material of the stop 12 can be polyoxymethylene or polyurethane, or other non-metallic parts with deformability, without specific limitation.

[0035] Optionally, the preset position of the stop 12 can be understood as follows: along the conveying direction X, the distance between the stop 12 and the conveying end 221 can be pre-adjusted to a preset distance L according to the cooperation relationship between the basket and the sheet conveying mechanism 2. At this time, the stop 12 is in the preset position. During the process of the sheet conveying mechanism 2 extending to convey the silicon wafer 4 to the basket, the silicon wafer 4 is stopped by the stop 12 at the preset position and can be carried by the basket. It is understood that the preset distance L can be adaptively adjusted according to the specific size of the basket, the cooperation relationship between the basket and the sheet conveying mechanism 2, etc., as long as the silicon wafer 4 can be stopped by the stop 12 at the preset position and can be carried by the basket, without specific limitations.

[0036] Figure 4 The diagram shown is a simplified schematic of the cooperation between the sheet stop mechanism and the bearing mechanism 3 provided in an embodiment of this disclosure. Figure 5 The diagram shown is a simplified schematic of the sheet stop mechanism and the base rod provided in an embodiment of this disclosure. Figure 6 The diagram shown is a simplified schematic of the sheet stop mechanism and the base rod provided in another embodiment of this disclosure. Figure 7 The diagram shown is a schematic of a sheet stop mechanism provided in an embodiment of this disclosure. Arrow Z points to a first direction Z, which is a direction perpendicular to the conveying direction X in the horizontal plane. The first direction Z can change according to the change of the conveying direction X, and will not be emphasized separately thereafter.

[0037] In some embodiments, such as Figures 4 to 7 The multiple toothed grooves 311 provided on the bottom rod 31 of the flower basket can include tooth bottom 311a and tooth top 311b respectively. The orthogonal projection of the stop member 12 along the conveying direction X on the bearing mechanism 3 is at least non-overlapping with the bottom rod 31, that is, each stop member 12 is located between two adjacent bottom rods 31, so that the stop member 12 avoids the bottom rod 31. When the silicon wafer 4 moves to the point of contact with the stop member 12, the stop member 12 is located in a preset position. The preset position is any position in the conveying direction X between tooth bottom 311a and tooth top 311b. By setting the stop 12 so that its orthogonal projection in the conveying direction X does not overlap with the bottom rod 31 and setting the preset position at any position between the tooth bottom 311a and the tooth top 311b, the stop 12 can stop the silicon wafer 4 extending into the basket while ensuring that the edge of the silicon wafer 4 can at least extend into the tooth groove 311 of the bottom rod 31. However, the edge of the silicon wafer 4 extending into the tooth groove 311 will not contact the bottom rod 31, thus preventing the silicon wafer 4 from having a hard collision with the basket. After the stop 12 is released from the silicon wafer 4, the stopped silicon wafer 4 can abut against the inner wall of the tooth groove 311 under the action of gravity, thereby realizing the support of the bottom rod 31 on the silicon wafer 4.

[0038] Optionally, such as Figure 4 and Figure 5When the wafer conveying mechanism 2 conveys the silicon wafer 4 from the conveying end 221 to the carrying mechanism 3, along the conveying direction X, there is a first distance L1 from the preset position to the tooth root 311a, and a second distance L2 between the tooth root 311a and the tooth tip 311b. The ratio of the first distance L1 to the second distance L2 is in the range of 1 / 3 to 2 / 3. This is so that after the stop member 12 disengages from the silicon wafer 4, the silicon wafer 4, which has stopped moving, can more stably abut against the inner wall of the tooth groove 311 under the action of gravity, preventing the silicon wafer 4 from detaching from the tooth groove 311 and improving the stability of the base rod 31 in carrying the silicon wafer 4.

[0039] It is understandable that the ratio of the first distance L1 to the distance from the tooth root 311a to the tooth tip 311b can be, for example, 1 / 3, 1 / 2, 2 / 3, etc., and can be adjusted adaptively according to actual needs without being specifically limited.

[0040] In some embodiments, two or more stop members 12 are arranged at intervals along the first direction Z. The connecting bracket 11 includes a connecting portion 111 and two or more mounting portions 112. The connecting portion 111 extends along the first direction Z and is detachably connected to the sheet conveying mechanism 2. The two or more mounting portions 112 are connected to the side of the connecting portion 111 away from the sheet conveying mechanism 2, and each mounting portion 112 is connected to a stop member 12. By providing the connected connecting portion 111 and the two or more mounting portions 112, the connecting bracket 11 forms a U-shaped, E-shaped, or other structure with the opening facing the flower basket when viewed from the vertical direction Y. This ensures that the stop member 12 connected to each mounting portion 112 will not interfere with the bottom rod 31 when entering the flower basket along the conveying direction X, thereby allowing the stop member 12 to be adjusted to a preset position.

[0041] In this embodiment of the disclosure, two mounting portions 112 are provided, and the connecting portion 111 and the mounting portion 112 can be integrally formed to form a U-shaped structure with the opening facing the flower basket when viewed from the vertical direction Y.

[0042] In addition, the connecting part 111 has a mounting point 111a at the center position in the first direction Z. The connecting part 111 is detachably connected to the sheet conveying mechanism 2 at the mounting point 111a so that the sheet stop mechanism 1 can be easily and quickly loaded and unloaded through the mounting point 111a. Furthermore, the multiple connecting parts 111 and the stop members 12 are symmetrically arranged on both sides relative to the mounting point 111a to improve the support stability of the stop members 12.

[0043] Specifically, the connecting part 111 is connected to the side of the sheet conveying mechanism 2 away from the conveyed sheet. The mounting part 112 includes a first connecting section 1121 and a second connecting section 1122. The first connecting section 1121 extends along the conveying direction X, and one end of the first connecting section 1121 is connected to the connecting part 111. The second connecting section 1122 extends along the vertical direction Y, and one end of the second connecting section 1122 is connected to the other end of the first connecting section 1121. The other end of the second connecting section 1122 is connected to a stop member 12 on the side facing the sheet conveying mechanism 2. The two ends of the stop member 12 in the vertical direction Y are respectively located on both sides of the silicon wafer 4 conveyed by the sheet conveying mechanism 2. By setting the first connecting section 1121 and the second connecting section 1122, the connected sheet stop mechanism 1 can be prevented from interfering with the conveyor belt of the sheet conveying mechanism 2, while the stop member 12 can be set at the position for stopping the silicon wafer 4.

[0044] Optionally, the end of the second connecting segment 1122 that is away from the first connecting segment 1121 in the vertical direction Y is flush with the upper end of the stop member 12, and the two ends of the stop member 12 in the first direction Z are flush with the two ends of the second connecting segment 1122 in the first direction Z. That is, the shape and size of the stop member 12 can be matched according to the shape of the second connecting segment 1122, and are not specifically limited.

[0045] It is understood that the first connecting segment 1121 and the second connecting segment 1122 can be integrally formed, and the straight segment can be bent into an L-shaped structure by bending, so that the first connecting segment 1121 and the second connecting segment 1122 extend in different directions after bending. Optionally, the length of the first connecting segment 1121 in the conveying direction X can be 2 / 3 of the length of the second connecting segment 1122 in the vertical direction Y, so as to ensure the bending strength during bending.

[0046] For example, the stop member 12 is positioned at a height higher than the upper surface of the silicon wafer 4 in the vertical direction Y, so that the stop member 12 can be used to stop the silicon wafer 4. Further, the height of the stop member 12 above the upper surface of the silicon wafer 4 in the vertical direction Y is a first height H1, and the height from the center of the tooth tip 311b connected to the upper sidewall of the tooth groove 311 where the silicon wafer 4 is located to the upper surface of the silicon wafer 4 is a second height H2. The second height H2 is higher than the first height H1, so that after the basket rises one insertion position in the vertical direction Y, the stop member 12 can disengage from the previous silicon wafer 4, and when the sheet conveying mechanism 2 drives the sheet stop mechanism 1 to retract in the conveying direction X, the stop member 12 can retract in the conveying direction X without interfering with the silicon wafer 4.

[0047] It is understandable that the second height H2 is at least 5mm higher than the first height H2, such as 5mm, 7mm, 9mm, etc. It can be adaptively adjusted according to the gap between adjacent toothed grooves 311 set on the bottom rod 31 and the size of the toothed grooves 311, without being specifically limited.

[0048] In some alternative embodiments, the stop member 12 is detachably connected to the connecting bracket 11. For example, the stop member 12 can be detachably connected to the side of the second connecting section 1122 facing the conveying end 221 by bolts, or it can be glued to the second connecting section 1122 by adhesive, or it can be achieved by snap-fit ​​connection, etc., without specific limitation. In the embodiments of this disclosure, the stop member 12 is detachably connected to the second connecting section 1122 by bolts, and the bolts are not exposed from the side of the stop member 12 facing the conveying end 221 along the conveying direction X, thereby ensuring that the silicon wafer 4 always only abuts against the stop member 12, avoiding hard collision between the silicon wafer 4 and the bolt.

[0049] Optionally, the thickness of the stop member 12 in the conveying direction X can be adaptively adjusted according to the material, deformation, etc. of the stop member 12, without being specifically limited.

[0050] In some alternative embodiments, such as Figure 5 and Figure 6 The distance between the two stoppers 12 in the first direction Z can be adaptively adjusted according to the actual width of the silicon wafer 4 in the first direction Z and the arrangement of the bottom rods 31 in the basket. The distance between the two stoppers 12 in the first direction Z is not greater than the width of the silicon wafer 4 in the first direction Z. For example, when the interval between the two bottom rods 31 in the basket is large in the first direction Z, the two stoppers 12 can be located between the two bottom rods 31 in the first direction Z. Alternatively, when the interval between the two bottom rods 31 in the basket is small in the first direction Z, the two stoppers 12 can be located on the outside of the two bottom rods 31 respectively in the first direction Z, so as to meet the stopping of silicon wafers 4 of different specifications and sizes and increase the range of use.

[0051] Optionally, along the first direction Z, there is a third distance L3 between the edge of the stop 12 and the edge of the bottom rod 31. The third distance L3 is at least greater than or equal to 10mm, such as 10mm, 12mm, 15mm, etc. It can be adaptively adjusted according to different specifications of the flower basket and is not specifically limited.

[0052] In some embodiments, the distance from the stop member 12 to the conveying end 221 of the sheet conveying mechanism 2 is adjustable. The sheet stop mechanism 1 further includes a drive member 13, which is connected to the sheet conveying mechanism 2 and connected to a connecting bracket 11. The drive member 13 is configured to drive the connecting bracket 11 to move along the conveying direction X of the sheet conveying mechanism 2 to adjust the distance from the stop member 12 to the conveying end 221. The drive member 13 allows for convenient and quick matching of the stop member 12's position in the conveying direction X according to the actual needs of different working conditions, enabling the stop member 12 to be used to stop the silicon wafer 4.

[0053] Optionally, the drive component 13 can be, for example, an electric push rod or a cylinder, and can be adapted to meet actual needs without being specifically limited. In this embodiment, the drive component 13 is set as an electric push rod so that the stop component 12 can be easily and quickly adjusted in the conveying direction X distance.

[0054] Understandably, the drive unit 13 may also include a mounting plate 131 for removable connection to the bottom of the sheet conveying mechanism 2 to facilitate the loading and unloading of the sheet stop mechanism 1.

[0055] This disclosure also provides a sheet loading and unloading system, such as Figure 1 and Figure 2 The sheet feeding and unloading system 10 includes a sheet conveying mechanism 2, a carrying mechanism 3, and a sheet stop mechanism 1. The sheet conveying mechanism 2 is configured to convey sheets along the conveying direction X and has a conveying end 221. The carrying mechanism 3 is disposed along the conveying direction X on the side of the sheet conveying mechanism 2 facing the conveying end 221 and is configured to carry the sheets conveyed from the conveying end 221. The sheet stop mechanism 1 is connected to the sheet conveying mechanism 2 and is configured to stop the sheets conveyed from the conveying end 221 of the sheet conveying mechanism 2 to the carrying mechanism 3.

[0056] It is understood that the sheet material stop mechanism 1 can be referred to the relevant descriptions of the above embodiments, and will not be repeated here.

[0057] Specifically, the sheet conveying mechanism 2 includes a first conveying component 21 and a second conveying component 22. The first conveying component 21 is configured to convey sheet material. The second conveying component 22 is disposed on one side of the first conveying component 21 and conveys the sheet material from the first conveying component 21. The conveying end 221 is located at the end of the second conveying component 22 away from the first conveying component 21. A sheet stop mechanism 1 is disposed on the second conveying component 22. The second conveying component 22 can extend along the conveying direction X to drive the sheet material at the conveying end 221 into the bearing mechanism 3. The sheet stop mechanism 1 can stop the sheet material extending into the bearing mechanism 3. Optionally, the specific structure of the sheet conveying mechanism 2 and its cooperation with the bearing mechanism 3 and the sheet stop mechanism 1 can be referred to the relevant descriptions in the above embodiments, and will not be repeated here.

[0058] In the embodiments of this disclosure, unless otherwise specified, the connection can be a detachable connection using bolts and nuts, screws, clips, magnetic attraction, etc. In some connections where there is no particular requirement for a detachable fit, a non-detachable connection can be achieved through welding, bonding, or other methods.

However, it should be noted that the advantages, benefits, and effects mentioned in this disclosure are merely examples and not limitations, and should not be considered as essential features of each embodiment of this disclosure.
