The separating device 1 comprises a fan 16, a negative pressure pipe 17, a suction pickup mechanism 11, a discharging mechanism 13 and a mounting frame 12, wherein the fan 16 is communicated with the negative pressure pipe 17 through a flexible connection to provide negative pressure for the suction pickup mechanism 11. The pick-up mechanism 11 includes a pick-up member 111 for picking up tobacco leaves, and a moving member 112 for changing a moving direction of the tobacco leaves picked up by the pick-up member 111, and the discharge mechanism 13 for separating the picked-up tobacco leaves from the pick-up mechanism 11.

The suction pick-up mechanism 11 is matched with the unloading mechanism 13, so that tobacco leaves needing to be separated into bins fall onto the conveying mechanism of the collecting device 2.

After the tobacco leaves are graded, the tobacco leaves are placed into the same conveying device 3 one by one, the conveying device 3 conveys the tobacco leaves towards the direction of the sorting device 1, when the tobacco leaves reach the position of the sorting device 1, the suction pick-up part 111 of the suction pick-up mechanism 11 sucks the tobacco leaves, the moving part 112 of the suction pick-up mechanism 11 is matched with the suction pick-up part 111 to change the moving direction of the tobacco leaves, and when the tobacco leaves move to the unloading mechanism 13, the suction pick-up part 111, the moving part 112 and the unloading mechanism 13 are matched to separate the tobacco leaves from the suction pick-up part 111 and fall onto the conveying surface of the conveying mechanism of the collecting device 2.

In the invention, the conveying device 3 mainly refers to a tobacco conveying belt conveyor, and the running speed of a conveying belt of the tobacco conveying belt conveyor is relatively high so as to improve the conveying efficiency. Of course, the running speed of the conveying belt is matched with the speed of the suction pickup mechanism 11, so that the sorting efficiency is affected due to too low speed, and the sorting effect is possibly affected due to the fact that part of tobacco leaves are not sucked by the suction pickup mechanism 11 due to too high speed.

The distance between the frame and the conveyor belt can not be too large, if the distance is too large, the time for picking up tobacco leaves by the picking-up component 111 can be increased, so that the efficiency of the picking-up mechanism 11 is affected, even the picking-up mechanism 11 can not pick up all tobacco leaves, and the sorting effect is greatly affected.

The pick-up mechanism 11 of the cartridge device 1 comprises a pick-up member 111 and a moving member 112.

The number of the suction pipes 1111 mounted on the suction pipe holder 1112 may be 1 or more, and the cross-sectional shape of the suction pipe 1111 may be circular, square or triangular, and may be set according to actual needs. The suction pipe holder 1112 may be provided in various forms as long as the suction pipe 1111 mounted thereon can be positioned above the conveying direction of the tobacco conveying belt conveyor while the suction pipe 1111 and the quick cylinder 1123 can be connected therethrough. The cylinder mount 1122 may be provided in various forms as long as it enables the quick cylinder 1123 mounted thereon to be connected to the diagonal cylinder 1121. In the present invention, the number of the negative pressure suction pipes 1111 is preferably 2, and the cross-sectional shape thereof is circular. The suction pipe bracket 1112 is composed of a horizontal mounting plate and a vertical mounting plate, the horizontal mounting plate and the vertical mounting plate are connected to form an inverted T-shaped member, two mounting through holes are formed in the horizontal mounting plate, and two negative pressure suction pipes 1111 are mounted on the suction pipe bracket 1112 through the two mounting through holes; a screw hole is provided between the two mounting holes, through which the quick cylinder 1123 is connected to the suction pipe holder 1112. The length of the horizontal mounting plate is matched with the length of most tobacco leaves after grading. The cylinder bracket 1122 is an integrally formed bending plate, and includes a horizontal portion and an upwardly inclined portion, the upwardly inclined portion extending toward the vertical mounting plate of the suction pipe bracket 1112; the horizontal portion is provided with a through hole through which the quick cylinder 1123 is mounted on the cylinder mount 1122; the upward inclined portion is provided with a screw hole or a bolt through hole, and the diagonal cylinder 1121 is connected to the cylinder mount 1122 through the screw hole or the bolt through hole.

The mounting frame 12 of the sorting device 1 is mainly intended to bring the pick-up mechanism 11 and the discharge mechanism 13 into a suitable position so as to be able to cooperate with each other for sorting tobacco leaves, so that the mounting frame 12 can be provided in various forms as long as the above-mentioned object is achieved. In the present invention, the mounting frame 12 of the cartridge device 1 spans the conveying direction of the conveying device 3, comprising side brackets 122 and mounting plates. The side bracket 122 is disposed on one side of the conveying surface of the conveying device 3, and includes a side plate 1224, where the side bracket 122 is shaped as a side-turned right trapezoid: and the right-angle waist of the right trapezoid is turned 90 degrees by taking the vertex of the base angle with the right angle in the right-angle trapezoid as a supporting point. The right-angle waist of the right trapezoid is a side bracket bottom edge 1221, the upper bottom edge of the right trapezoid is a side bracket first side edge 1223, the lower bottom edge of the right trapezoid is a side bracket second side edge, the hypotenuse waist of the right trapezoid is a side bracket top edge 1222, and the side bracket bottom edge 1221 extends along the conveying direction of the tobacco conveying belt conveyor. Side panels 1224 included in side brackets 122 are also right trapezoid shaped to roll over, fully engaging the sides of side brackets 122. The bottom edge 1221 of the side bracket is provided with a mounting hole, and the bin separation device 1 is mounted on the frame above the tobacco conveying belt conveyor through the mounting hole. The mounting plates comprise a first mounting plate 1 and a second mounting plate 2. The first mounting plate 1 is a V-shaped angle plate, the shaft of the V-shaped angle plate extends along the width direction of the tobacco conveying belt conveyor, and the V-shaped angle plate rotates anticlockwise by taking the vertex of the angle part as a supporting point, so that the projections of the two outer edges of the opening of the V-shaped angle plate on the axial direction are overlapped on the horizontal plane; the V-shaped angle plate is positioned in the conveying direction of the tobacco conveying belt conveyor, and the opening of the V-shaped angle plate faces away from the conveying direction of the conveying device 3. The V-shaped gusset ends are connected to side panels 1224 of side brackets 122 and the openings are connected to side bracket first side edges 1223. The second mounting plate 2 is connected with the edge of the V-shaped opening of the V-shaped angle plate, which is far away from the tobacco leaf conveying belt machine in the axial direction, the adjacent side of the edge of the second mounting plate 2 connected with the V-shaped angle plate is connected with the side bracket 122, and the projection of the second mounting plate 2 on the side plate 1224 of the side bracket 122 is parallel or coincident with the top edge 1222 of the side bracket. The above is the optimal arrangement for mounting the frame 12. The mounting frame 12 may be provided in other ways as well. For example, side brackets 122 are provided in the form of pure brackets, not including side panels 1224; the first mounting plate 1 is perpendicular to the tobacco conveying belt conveyor, the edge of the first mounting plate 1 far away from the tobacco conveying belt conveyor is connected with the second mounting plate 2, and in the conveying direction of the tobacco conveying belt conveyor, the first mounting plate 1 and the second mounting plate 2 form an inclined upward slope; an adjacent side of the edge of the first mounting plate 1 far away from the tobacco conveying belt machine is connected with a first side 1223 of a side bracket equivalent to the upper bottom edge of the right trapezoid, and an adjacent side of the edge of the second mounting plate 2 connected with the first mounting plate 1 is connected with a top edge 1222 of the side bracket equivalent to the hypotenuse of the right trapezoid; the side bracket 122 has no bottom edge, and only the bottoms of the first side 1223 and the second side of the side bracket are provided with mounting holes, and the bin splitting device 1 is mounted on the frame above the tobacco conveying belt conveyor through the mounting holes at the bottoms of the two sides. In addition, the mounting frame 12 spans the conveying direction of the conveying device 3, and the mounting frame 12 may or may not be perpendicular to the conveying direction of the conveying device 3, that is, the angle at which the longitudinal direction of the mounting frame 12 intersects the conveying direction of the conveying device 3 may be 90 °, or may be less than 90 °, or may be greater than 90 ° and less than 180 °.

The diagonal-pulling air cylinder 1121 in the moving part 112 of the suction pickup mechanism 11 is installed on the second installation plate 2 along the direction of the top edge 1222 of the side bracket, and the lower end of the diagonal-pulling air cylinder 1121 is connected with the air cylinder bracket 1122, so that the suction pickup mechanism 11 can pick up tobacco leaves and move the tobacco leaves under the support of the installation frame 12. After the tobacco leaves are picked up by the suction pick-up mechanism 11, the tobacco leaves are matched with the unloading mechanism 13 to fall on the conveying mechanism of the collecting device 2. The unloading mechanism 13 is an unloading plate, the length direction of the unloading plate is intersected with the conveying direction of the tobacco conveying belt conveyor, namely, the unloading plate spans across the tobacco conveying belt conveyor, is connected with the edge of the first mounting plate 1 close to the tobacco conveying belt conveyor, and extends in the direction away from the first mounting plate 1 and in the conveying direction back to the tobacco conveying belt conveyor. The stripper plate is formed by bending a horizontal plate 131 obliquely upwards, namely the stripper plate comprises the horizontal plate 131 and a bending part 132, wherein the bending part 132 is far away from the first mounting plate 1. The inclined upward bending portion of the stripper plate cannot be excessively high, that is, the outer edge of the bending portion 132 is located at a height, that is, the outer edge of the stripper plate away from the first mounting plate 1 cannot be excessively high; when the inclined cylinder 1121 extends out and the lower end thereof reaches the lowest position, the inclined cylinder 1121 forms a certain distance with the edge of the bending part 132 far away from the first mounting plate 1, and the formed distance is enough to enable the suction pickup mechanism 11 to smoothly operate. Because if the inclined upward bending portion is too high, the operation of the suction pickup mechanism 11 may be hindered, and the task of sorting tobacco leaves cannot be completed. The edge of the bent part 132 of the stripper plate far away from the first mounting plate 1 is provided with a notch 133, the notch 133 extends towards the direction of the first mounting plate 1, and the notch 133 extends a certain distance towards the direction of the first mounting plate 1 after reaching the horizontal plate 131 of the stripper plate. The width of the notch 133 is slightly longer than the diameter of the suction pipe 1111, so long as the suction pipe 1111 can be smoothly entered into the notch 133. The discharge plate corresponding to one suction mechanism 11 is provided with notches 133, and the number of the notches 133 is matched with that of the negative pressure suction pipes 1111 of the suction mechanism 11. In the present invention, two vacuum pipettes 1111 with two notches 133 are preferred. The transport mechanism of the collecting device 2, i.e. the collecting belt, is located below the stripper plate and the outer edge of the collecting belt is further away from the mounting frame 12 than the outer edge of the stripper plate fold 132.

When the equipment is in an initial state and is not started to operate, the inclined pulling air cylinder 1121 is in an extending state, the quick air cylinder 1123 is in a retracting state, the suction pickup component 111 of the suction pickup mechanism 11 is positioned on one side of the stripper plate far away from the mounting frame 12, and the bottom of the negative pressure suction pipe 1111 is far away from the tobacco conveying belt conveyor. After the equipment is operated, the fan 16 provides negative pressure for the negative pressure suction pipe 1111 through the negative pressure pipe 17, and after receiving a system instruction, the quick cylinder 1123 is quickly extended to enable the suction pipe rack to be quickly downwards so as to enable the negative pressure suction pipe 1111 to be quickly close to the tobacco conveying belt machine, wherein the distance between the negative pressure suction pipe 1111 and the conveying belt just accommodates smooth passing of tobacco leaves; the tobacco leaves move below the negative pressure suction pipe 1111 along with the conveying belt, the negative pressure suction pipe 1111 sucks the tobacco leaves, at the moment, the quick cylinder 1123 is quickly retracted, so that the negative pressure suction pipe 1111 is quickly far away from the tobacco conveying belt machine, and then the oblique pulling cylinder 1121 starts to retract, so that the suction pickup part 111 is driven to move obliquely upwards towards the mounting frame 12; when two negative pressure suction pipes 1111 enter the opening 133 of the stripper plate, tobacco leaves sucked by the negative pressure suction pipes 1111 are under the stripper plate, the inclined pulling cylinder 1121 continues to retract, the negative pressure suction pipes 1111 continue to incline upwards, the tobacco leaves are blocked by the stripper plate and are separated from the negative pressure suction pipes 1111, and fall onto the collecting belt due to self gravity, and the collecting belt conveys the tobacco leaves falling onto the collecting belt to the corresponding collecting frame.

In the invention, the fan 16 is a variable frequency fan, and the wind speed, the wind quantity and the wind pressure are all adjustable. The weight range of each tobacco leaf may be different for different batches or different varieties of tobacco leaves, and the parameters of the blower 16 may be adjusted to provide a suitable negative pressure for the suction pickup mechanism 11, so that the suction pickup mechanism 11 can smoothly pick up and move the tobacco leaves.

In the preferred embodiment of the present invention, the suction member 111 of the suction mechanism 11 is provided with two suction pipes 1111, so that the tobacco leaves passing under the suction member 111 can be smoothly sucked by the suction pipes 1111. When a piece of tobacco leaves passes under the suction pickup part 111 of the suction pickup mechanism 11, since the passing position is not necessarily just under the horizontal mounting plate of the suction pipe bracket 1112, for example, more than one half of the horizontal mounting plate is located outside the passing position of the tobacco leaves, if only one negative pressure suction pipe 1111 is provided at the central position of the horizontal mounting plate, the negative pressure suction pipe 1111 cannot suck the tobacco leaves successfully, but if two negative pressure suction pipes 1111 are provided, both negative pressure suction pipes 1111 are located at the quarter length position of the horizontal mounting plate, and the negative pressure suction pipe 1111 close to the piece of tobacco leaves can suck the piece of tobacco leaves smoothly. The two suction pipes 1111 are not necessarily located in the quarter length of the horizontal mounting plate, but may be located in the fifth or sixth length of the horizontal mounting plate, but the quarter length is the most preferable because the suction by the other suction mechanism 11 is better when the area of one tobacco close to three quarters is not located under the horizontal mounting plate. In addition, if a relatively large piece of tobacco passes directly under the suction pickup member 111 of the suction pickup mechanism 11, if only one negative pressure suction pipe 1111 is provided at the center position of the horizontal mounting plate, there is a possibility that the suction force provided by the negative pressure suction pipe 1111 cannot firmly pick up the tobacco, and two negative pressure suction pipes 1111 can firmly pick up the tobacco; if the tobacco leaves are smaller, it is possible that the two negative pressure suction pipes 1111 each pick up one tobacco leaf, and the tobacco leaf pick-up efficiency is improved. The angle between the negative pressure suction pipe 1111 and the tobacco conveying belt is 45-90 degrees, and the preferable scheme is that the negative pressure suction pipe 1111 is perpendicular to the tobacco conveying belt, because the suction force of the negative pressure suction pipe 1111 to the tobacco is maximum when the negative pressure suction pipe 1111 and the tobacco conveying belt are perpendicular.

In the invention, the quick cylinder 1123 is arranged on the moving part 112 of the suction pickup mechanism 11, and the quick cylinder 1123 is connected with the negative pressure suction pipe 1111 through the suction pipe bracket 1112, so that the negative pressure suction pipe 1111 can be quickly close to the tobacco conveying belt conveyor, and can be quickly far away from the tobacco conveying belt conveyor after the tobacco is picked up, thereby saving time and improving efficiency. Even if the quick cylinder 1123 is not provided, the suction pickup part 111 and the moving part 112 can cooperate to pick up and convey tobacco leaves, but the tobacco leaves can only be slowly conveyed by the acting force of the oblique-pulling cylinder 1121, the consumed time is long, and the efficiency is relatively low. The moving part 112 of the suction pickup mechanism 11 is provided with a diagonal cylinder 1121, so that the tobacco picked up by the suction pickup part 111 changes the moving direction, thereby smoothly moving the tobacco above the tobacco collecting belt. Compared with a gear train and other commutators, the diagonal cylinder 1121 has the advantages of simple structure, small occupied space and relatively low cost.

In the invention, the discharging mechanism 13 is a discharging plate, the discharging plate is provided with the opening 133, the depth of the opening 133 is larger than the width of the bending part 132 of the discharging plate, and the opening 133 is matched with the negative pressure suction pipe 1111, so that when the tobacco leaves move to the position of the discharging plate along with the inclined-pull air cylinder 1121, the whole tobacco leaves can be completely positioned below the bending part 132 of the discharging plate, and the tobacco leaves are ensured to be separated from the negative pressure suction pipe 1111 and smoothly fall onto the tobacco leaf collecting belt. If the stripper plate is not provided with the opening 133, when the tobacco leaves move to the position where the stripper plate is located, only a part of the tobacco leaves is located below the bent portion 132 of the stripper plate, it is possible that the force applied to the tobacco leaves by the stripper plate cannot separate the tobacco leaves from the negative pressure suction pipe 1111, even if the tobacco leaves can separate from the negative pressure suction pipe 1111, the tobacco leaves may drift out of the tobacco leaf collecting belt in the falling process due to uneven stress of the tobacco leaves. The depth of the opening 133 is greater than the width of the bent portion 132 of the stripper plate, that is, after the opening 133 extends to the horizontal plate 131, it still continues to extend a certain distance toward the direction of the first mounting plate 1211, so that the negative pressure suction pipe 1111 can be prevented from colliding with the horizontal plate 131 in the process of tilting upwards. The suction pick-up mechanism 11 is matched with the unloading mechanism 13, so that after tobacco leaves are separated from the negative pressure suction pipe 1111 and fall onto the collecting belt, the inclined pulling cylinder 1121 continues to move obliquely upwards for a certain distance, and the upward movement is stopped when the negative pressure suction pipe 1111 is positioned above the horizontal plate 131 of the unloading plate. At this time, the negative pressure in the negative pressure suction pipe 1111 has little influence on the tobacco leaves, and the tobacco leaves can smoothly drop onto the collecting belt. If the stripper plate is only a horizontal plate 131 without the bending portion 132, the tobacco leaves can be separated from the negative pressure suction pipe 1111, but the tobacco leaves are just below the negative pressure suction pipe 1111 after being separated from the negative pressure suction pipe 1111, i.e. within the negative pressure influence range of the negative pressure suction pipe 1111, the tobacco leaves may not smoothly and rapidly fall onto the collecting belt. The discharging mechanism 13 may be other arrangements, such as a valve arranged in the negative pressure suction pipe 1111 or at the position where the negative pressure suction pipe 1111 is communicated with the negative pressure pipe 17, and the opening and closing of the valve is controlled to make the negative pressure suction pipe 1111 suck and release tobacco leaves.

The side bracket 122 of the mounting frame 12 is a side bracket 122 comprising a side plate 1224. This structure comprises the side bracket 122 and the side plate 1224 cooperating with the side bracket 122, so that the side bracket 122 is more stable. The side bracket 122 is arranged to be a pure bracket structure, and can also support the suction pick-up mechanism 11 and the stripper plate to finish tobacco leaf sorting, but the stability is poor. The first mounting plate 1211 of the mounting frame 12 is a side-turned V-shaped gusset that provides sufficient space for the pick-up mechanism 11 to operate so that the moving member 112 of the pick-up mechanism 11 does not rub or impact the first mounting plate 1211, reducing wear. If the first mounting plate 1211 of the mounting frame 12 is a straight plate perpendicular to the tobacco conveying belt, the suction pickup mechanism 11 and the discharge plate can be supported to complete the tobacco sorting, but the moving part 112 of the suction pickup mechanism 11 may rub or collide with the first mounting plate 1211, so that abrasion is caused, and the service life is affected.

In the present invention, the sorting device 1 includes the plurality of pick-up mechanisms 11, and the plurality of pick-up mechanisms 11 are sequentially distributed above the tobacco conveying belt along the length direction of the mounting frame 12, so that each tobacco can be picked up and moved onto the tobacco collecting belt, that is, the projection of the plurality of pick-up mechanisms 11 on the axis in the length direction of the mounting frame 12 coincides with the projection of the first mounting plate 1211 on the axis in the length direction of the mounting frame 12. All suction pick-up mechanisms 11 of the sorting device 1 can be arranged on the same straight line, namely on the same side of the mounting frame 12, but the distribution is too dense, and when two adjacent suction pick-up mechanisms 11 operate, friction or collision can occur, so that the sorting process of tobacco leaves is influenced. In order to make the two adjacent suction pickup mechanisms 11 have enough space to operate without interfering with each other, the suction pickup mechanisms 11 may be disposed on both sides of the mounting frame 12, that is, as shown in fig. 1,2 and 4, the suction pickup mechanisms 11 are uniformly disposed on both sides of the mounting frame 12 in the conveying direction of the tobacco conveying belt. The suction pickup mechanisms 11 on the same side are arranged, a distance capable of accommodating one suction pickup part 111 is reserved between the suction pickup parts 111 of two adjacent suction pickup mechanisms 11, and the position on the other side of the mounting frame 12 symmetrical to the position where the distance is positioned is the position where the suction pickup part 111 of the suction pickup mechanism 11 arranged on the other side of the mounting frame 12 is positioned. Accordingly, the position on the other side of the mounting frame 12 opposite to the position that is left between the moving members 112 of the adjacent two pick-up mechanisms 11 is the position where the moving member 112 of the pick-up mechanism 11 provided on the other side of the mounting frame 12 is located. The arrangement is such that tobacco leaves which are not picked up by the pick-up mechanism 11 on one side of the mounting frame 12 are smoothly picked up by the pick-up mechanism 11 on the other side of the mounting frame 12, i.e., each tobacco leaf can be picked up by the pick-up mechanism 11 and moved to the tobacco leaf collecting belt.

In the case that the suction pick-up mechanism 11 is disposed at both sides of the mounting frame 12, in order to make the binning mechanism more stable, the side bracket of the mounting frame 12 is also changed, as shown in fig. 2 and 4, on one side of the mounting frame 12, the aforementioned second side edge of the side bracket, which is equivalent to the lower bottom edge of the right trapezoid, extends for a certain distance along the conveying direction of the tobacco conveying belt, and the aforementioned mounting plate and side bracket 122 are disposed in the conveying direction of the conveying belt with the second side edge at the position as the symmetry axis. At this time, a new side bracket is formed, and the second side of the side bracket extending a certain distance in the conveying direction of the tobacco conveying belt is positioned on the vertical axis section of the new mounting frame 12, and the side plate on the side bracket is also formed in the above-described manner. Of course, the above is just a description mode, and in the new side bracket, the second side edge is not necessarily existed due to the symmetrical structure and the side plate, and the side plate is not formed by splicing two original side plates after extension. In the new side bracket, the first side 1223 of the original side bracket, which is equivalent to the upper bottom edge of the right trapezoid, becomes the new two sides, and the side plate is a plate matched with the shape of the new side bracket.

Through holes are formed in the side plates of the side brackets of the mounting frame 12, the negative pressure pipe 17 penetrates through the through holes and penetrates through the mounting frame 12, and the axis of the negative pressure pipe 17 is located on the vertical axis section of the mounting frame 12, so that the preferable negative pressure pipe 17 arrangement scheme is adopted. The negative pressure pipe 17 may be provided above the mounting frame 12 or at other positions as long as it communicates with the blower 16 and provides negative pressure to the negative pressure suction pipe 1111.

The tobacco leaf separating device comprises a plurality of units, namely a plurality of separating devices and a plurality of collecting devices are sequentially arranged above the tobacco leaf conveying belt conveyor along the conveying direction, and the separating devices are matched with the collecting devices. When the tobacco leaves of the same grade are conveyed by the tobacco leaf conveying belt conveyor, only one unit operates, namely one bin separating device and a collecting device matched with the bin separating device operate, and the rest units are stationary; when the tobacco conveying belt conveyor simultaneously conveys tobacco leaves with multiple grades, the multiple units are operated, namely the multiple bin dividing devices and the multiple collecting devices matched with the multiple bin dividing devices are operated, the belt conveyor simultaneously conveys tobacco leaves with two grades, the belt conveyor simultaneously conveys tobacco leaves with three grades, and the like. In order to improve the efficiency, when the tobacco conveying belt conveyor conveys tobacco leaves of the same grade, more than two units (including units) can be operated. Each suction means of each unit performs suction and movement of tobacco leaves according to the received system command.

The tobacco leaf separating equipment also comprises a compressor, an air source processor 14 and an electromagnetic valve 15, wherein the compressor is communicated with the air source processor 14, the air source processor 14 is communicated with the electromagnetic valve 15, and the electromagnetic valve 15 is communicated with the inclined pulling cylinder 1121 and the quick cylinder 1123, which belong to the prior art and are not described in detail. How to operate the diagonal cylinder 1121 and the fast cylinder 1123, and how to provide negative pressure for the suction pickup mechanism 11 by the fan 16 through the negative pressure pipe 17, which also belong to the prior art, are not described here again.

The foregoing is merely illustrative of the preferred embodiments of this invention, and it will be appreciated by those skilled in the art that variations and modifications may be made without departing from the principles of the invention, which is also intended to be considered as a limitation of the invention.
