Description

Technical Field

[0001] This invention belongs to the technical field of paper product packaging equipment, and particularly relates to a push-packing conveyor device. Background Technology

[0002] In the packaging and printing industry, gluing machines are widely used to fold and glue die-cut cardboard into shape. The output material is usually a compressed paperboard, such as cup sleeves, boxes, or trays made of corrugated cardboard. After being compacted and stacked at the discharge end of the gluing machine, this material is continuously output in a flat, plate-like form.

[0003] Currently, the industry generally uses manual operation for the post-packaging process of the materials output from the aforementioned carton gluing machine. That is, the operator stands at the discharge port of the carton gluing machine, manually groups the materials according to a predetermined quantity, and puts them into cartons to complete the packaging.

[0004] However, with the continuous improvement of the automation level of carton gluing machines, their production speed has increased rapidly, and the amount of material output per unit time is extremely large. To keep up with the production line pace, operators need to maintain a high level of concentration and perform frequent picking, stacking, and packing actions for extended periods, resulting in extremely heavy workloads. Furthermore, prolonged repetitive manual operations can easily lead to counting errors or packing chaos due to fatigue, not only reducing packaging efficiency but also making it difficult to ensure consistent product packaging quality. This has become a bottleneck restricting further improvement in the automation level of the entire carton gluing production line.

[0005] Therefore, it is necessary to provide a device that can automatically group and pack the sheet materials output by the box gluing machine to replace the existing manual operation method, reduce the labor intensity of workers, and improve production efficiency. Summary of the Invention

[0006] Based on this, and to address the aforementioned technical problems, a packing and conveying device is provided.

[0007] The technical solution adopted in this invention is as follows: A box-packing conveyor, characterized in that it comprises: A conveying channel for horizontally conveying paperboard-shaped materials arranged in a vertically stacked state from back to front, the conveying channel including a pair of first conveyor belts arranged at intervals in the left and right directions and running synchronously. A grouping mechanism includes a baffle, a grouping insert, and a first sensor. The baffle is used to: insert its head between the edge of the grouping marker material and the edge of the preceding material when the first sensor detects that the protruding edge of the grouping marker material is in contact with the rear side of the baffle head; and to push the preceding material forward to widen the gap when the grouping insert is inserted into the gap between the grouping marker material and the preceding material, and to shield the edges of the grouping marker material and the preceding material on the front and rear sides of the grouping insert. The grouping insert is used to insert into the gap after the head of the baffle is inserted between the edge of the grouping marker material and the preceding material to form a material group on its front side. Two alternating transport mechanisms are respectively located above and below the conveying channel. Each transport mechanism is used to clamp the material group from the front and back and transport it forward in a straight line to the transfer position. The transport mechanism includes a front stop and a rear stop that can move up and down and horizontally back and forth. The front stop is located in front of the rear stop. A transfer and packing mechanism is used to transfer and pack the material group located at the transfer position.

[0008] This invention can automatically group and pack the sheet materials output by the box gluing machine, reducing the labor intensity of workers and improving production efficiency. At the same time, during the grouping process, the elastic sheet first widens the gap between the grouping mark material and the previous material, and then the grouping insert plate is inserted between the grouping mark material and the previous material to prevent the paper material from being damaged by the grouping insert plate.

Detailed Implementation

[0010] The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be noted that the embodiments described in this specification are not exhaustive and do not represent the only embodiments of the present invention. The corresponding embodiments below are only for clearly illustrating the inventive content of this patent and are not intended to limit its implementation. For those skilled in the art, different variations and modifications can be made based on the embodiments described. Any variations or modifications that fall within the technical concept and inventive content of this invention and are obvious are also within the protection scope of this invention.

[0011] like Figure 1 As shown in the figure, this application provides a box-packing and conveying device, including a frame 1100, a conveying channel 1200, a grouping mechanism 1300, two handling mechanisms 1400, and a box-packing transfer mechanism 1500.

[0012] The conveyor channel 1200, the grouping mechanism 1300, the two handling mechanisms 1400, and the transfer and packing mechanism 1500 are all mounted on the frame 1100.

[0013] The conveyor channel 1200 is used for horizontally conveying paper sheet materials arranged in a vertically stacked state from back to front. It should be noted that, as... Figure 1 As shown in this application, the front-back direction refers to the x-direction, and the left-right direction refers to the y-direction.

[0014] In this context, the vertical stacking arrangement refers to the arrangement of each paper-board material in a vertical posture along the conveying direction, with the front and rear surfaces of adjacent paper-board materials touching each other. In this embodiment, the paper-board material refers to a cup sleeve made of corrugated paper, which is in a pressed state after being output from the gluing machine, thus forming a board shape. At intervals, 1-3 sheets of continuous paper-board materials will protrude in the left-right direction. These protruding materials (hereinafter referred to as group marking materials) are formed by the counting device of the gluing machine. In this embodiment, the left edge of the group marking material protrudes to the left.

[0015] In this embodiment, as Figure 2 As shown, the conveying channel 1200 includes a pair of first conveyor belts 1210.

[0016] A pair of first conveyor belts 1210 are arranged at intervals in the left and right directions, and are respectively fixed on the right support plate 1220 and the left support plate 1230. The first conveyor belts 1210 are driven by the same motor to achieve synchronous operation. This technology is conventional, and its specific structure and principle will not be described in detail here.

[0017] A transfer position is set at the front of the conveying channel 1200. A connecting rod 1240 in the left-right direction is connected between the right support plate 1220 and the left support plate 1230 at the position corresponding to the transfer position. A fall arrestor 1250 in the front-back direction is fixed on the connecting rod 1240. The upper surface of the fall arrestor 1250 is flush with the conveyor belt surface of the conveying channel 1200.

[0018] like Figure 2 and Figure 3 As shown, a right baffle 1221 corresponding to the rear and middle sections of the conveying channel 1200 is fixed on the right support plate 1220, and a left baffle 1231 corresponding to the middle section of the conveying channel 1200 is fixed on the left support plate 1230.

[0019] The grouping mechanism 1300 is located on the left side of the rear end of the conveying channel 1200, such as... Figure 4 As shown, it includes a base 1310, a baffle 1320, a grouping insert plate 1330, a first sensor 1340, a first linear drive module 1350, a mounting plate 1360, and a push plate 1370.

[0020] The base 1310 is a horizontal plate used to move closer to or further away from the conveyor channel 1200 in the left or right direction under the drive of the first linear drive module 1350. The first linear drive module 1350 is fixed on the mounting plate 1360, which is fixed to the frame 1100. The lower surface of the base 1310 has a slide, and the upper surface of the mounting plate 1360 has a slide rail that slides with the slide, serving as a guide when the base 1310 moves closer to or further away from the conveyor channel 1200 in the left or right direction.

[0021] like Figure 4 As shown, the baffle 1320 includes a baffle body 1321 and an elastic piece 1322 located on the front side of the baffle body 1321. Both are located above the base 1310 and face the front-back direction.

[0022] like Figure 5 As shown, the baffle body 1321 is fixed to the base 1310 by the first bracket 1323 and extends in the left and right direction, and the front side of its head has a first groove.

[0023] like Figure 4 As shown, the elastic sheet 1322 includes a straight section 1322a and an inclined section 1322b. As... Figure 6 As shown, the straight section 1322a is located within the first groove. The distance between the inclined section 1322b and the baffle body 1321 gradually increases from right to left away from the conveying channel 1200. The head end of the inclined section 1322b is integrally connected to the tail end of the straight section 1322a, and the tail end of the inclined section 1322b is fixed to the base 1310 via the second bracket 1324. (See Figure 1322b for details.) Figure 4 .

[0024] The grouping insert plate 1330 is parallel to the baffle body 1321 and is connected to the second linear drive module 1325. It is initially located between the baffle body 1321 and the inclined section 1322b. The second linear drive module 1325 is fixed on the base 1310.

[0025] like Figure 4 and Figure 7 As shown, the front side of the grouping insert plate 1330 has two vertically open second grooves 1331 arranged at left and right intervals, for the front and rear stops of the conveying mechanism 1400 to be inserted in the vertical direction.

[0026] The first sensor 1340 uses a photoelectric sensor, such as... Figure 4 and Figure 5 As shown, it is fixed to the mounting plate 1360 by the third bracket 1341, so that the first sensor 1340 is located just above the rear side of the head of the baffle 1320.

[0027] The pusher plate 1370 is used to push the grouped marking material in the left and right direction under the drive of the third linear drive module 1380 when the grouping insert plate 1330 and the baffle plate 1320 return to their original positions, so that the grouped marking material is flush with other materials and blocks the materials to prevent them from being carried out by the grouping insert plate 1330 and the baffle plate 1320. The third linear drive module 1380 is fixed on the base 1310.

[0028] Based on the above description of the grouping mechanism 1300, its process of completing one material grouping is as follows: The head of the baffle 1320 is initially located on the moving path of the left protruding edge of the grouping marker material. When the first sensor 1340 senses the left protruding edge of the grouping marker material, the grouping marker material just contacts the rear side of the head of the baffle 1320. At this time, the first linear drive module 1350 drives the baffle 1320 to move to the right via the base 1310, so that its head is inserted between the edge of the grouping marker material and the edge of the material preceding it. Then, the grouping insert plate 1330 approaches the material to the right under the drive of the second linear drive module 1325, passing the baffle... When the head of the sheet 1320 is reached, it pushes open the straight section 1322a, causing the straight section 1322a to push forward the previous material, thus widening the gap between the grouping marking material and the previous material for the grouping insert plate 1330 to insert. The elastic sheet 1322 and the baffle body 1321 respectively block the front and rear sides of the grouping insert plate, preventing the grouping insert plate 1330 from damaging the edges of the grouping marking material and the previous material when it is inserted into the gap. As the distance between the grouping marking material and the previous material is widened, the grouping insert plate 1330 is inserted between the previous material and the grouping marking material, thereby forming a material group on its front side. This material group is located exactly between the left baffle 1231 and the right baffle 1221. After the baffle 1320 and the grouping insert 1330 clamp the material group in front and behind the conveying mechanism 1400, they return to their original positions. During the return process, the push plate 1370 moves. When the grouping insert 1330 returns to its original position, the straight section 1322a of the elastic sheet 1322 returns to the first groove under the action of elastic self-restoring force.

[0029] To facilitate smooth insertion between materials and further prevent material damage, the vertical width of the heads of the baffle 1320 and the grouping insert 1330 gradually narrows in the direction approaching the conveying channel (i.e., from left to right). Furthermore, the front side of the head of the grouping insert 1330 is an arc-shaped surface whose distance from its rear side gradually decreases in the direction approaching the conveying channel. The straight section 1322a of the elastic sheet 1322 has its head angled forward. See [reference needed]. Figure 6To prevent the elastic sheet 1322 from folding backward during the process of the grouping insert plate 1330 returning to its original position, thus preventing the straight section 1322a from returning to the first groove, and at the same time, the length of the straight section 1322a in the left-right direction is greater than the length of each second groove 1331 in the left-right direction, to prevent the straight section 1322a from being stuck in the second groove 1331.

[0030] Two conveying mechanisms 1400 are respectively positioned above and below the conveying channel 1200 to operate alternately. Each conveying mechanism 1400 is used to clamp the material group from the front and rear and convey it forward in a straight line to the aforementioned transfer position.

[0031] The two conveying mechanisms 1400 have the same structure. In this embodiment, the upper conveying mechanism 1400 is taken as an example. Figure 8 As shown, it includes a front gear socket 1410, a rear gear socket 1420, a second conveyor belt 1430, two first guide rails 1440 in the front-to-back direction, a fourth linear drive module 1450, a first lifting module 1460, a second lifting module 1470, a front gear plug 1480, and a rear gear plug 1490.

[0032] like Figure 9 As shown, the front deflector socket 1410 is fixed to the belt of the second conveyor belt 1430 by a belt clip 1411. The front deflector socket 1410 is located in front of the rear deflector socket 1420, and both are slidably mounted on two first guide rails 1440. A fourth linear drive module 1450 is fixed to the upper surface of the front deflector socket 1410. The fourth linear drive module 1450 is connected to the upper surface of the rear deflector socket 1420 through a connecting arm 1451, so that the front deflector socket 1410 is connected to the rear deflector socket 1420 through the fourth linear drive module 1450.

[0033] The front gear plug 1480 is located in front of the rear gear plug 1490. The two are connected to the front gear socket 1410 and the rear gear socket 1420 respectively through the first lifting module 1460 and the second lifting module 1470.

[0034] Both the front deflector 1480 and the rear deflector 1490 have two insert rods arranged at left and right intervals, and the two insert rods correspond to the two second grooves 1331 respectively.

[0035] Based on the above description, the front stop 1480 and the rear stop 1490 can move horizontally back and forth synchronously under the drive of the second conveyor belt 1430. Of course, in other possible embodiments, the front stop 1480 and the rear stop 1490 can move horizontally back and forth independently. The front stop 1480 and the rear stop 1490 can approach or move away from each other under the drive of the fourth linear drive module 1450, thereby clamping or releasing the material group. The front stop 1480 and the rear stop 1490 can also be lifted and lowered under the drive of the first lifting module 1460 and the second lifting module 1470, respectively.

[0036] The alternating operation process of the two handling mechanisms 1400 is as follows: First, for ease of understanding, the front and rear stops of the upper and lower conveying mechanisms are distinguished below: The front and rear stops of the upper conveying mechanism are defined as S1 and S2, respectively, and the front and rear stops of the lower conveying mechanism are defined as X1 and X2, respectively.

[0037] like Figure 10 As shown in STEP 1, the front derailleur S1 is initially in the extended state and located slightly in front of the grouping plate 1330 (defined as initial position P1), while the rear derailleur S2 is initially in the retracted state, with its initial position set to P2. The front derailleur X1 and the rear derailleur X2 are waiting at the front waiting position P3 and the rear waiting position P4, respectively.

[0038] After exiting the box-gluing machine, the material enters the conveying channel 1200. When the material encounters the front stop S1, the upper conveying mechanism 1400 is activated, causing the front stop S1 and the rear stop S2 to move forward at a speed consistent with the conveying channel 1200. When the front stop S1 reaches the blocking position P5, it stops moving. At this time, the rear stop S2 is exactly at the front waiting position P3. (See below) Figure 10 STEP2.

[0039] At the same time, the grouping plate 1330 of the grouping mechanism 1300 is fully inserted between the grouping mark material and the previous material to form a material group. At this time, the rear stop S2 and the front stop X1 are simultaneously inserted into the second groove from the front waiting position P3 in the vertical direction. See below. Figure 10 STEP3.

[0040] After the rear deflector S2 is inserted into the second groove 1331, it moves forward slightly and clamps the material group via the fourth linear drive module 1450. Then, the front deflector S1 and rear deflector S2 quickly move the material group forward to the transfer position. (See below) Figure 10 Step 4. After the transport is completed, the front gear lever S1 and the rear gear lever S2 retract and move to the front waiting position P3 and the rear waiting position P4 to wait.

[0041] After the front insert X1 is inserted into the second groove 1331, it also moves forward slightly quickly. The purpose of this forward slight movement is to avoid the group insert plate 1330 and provide space for the group insert plate 1330 to exit and return to its original position. The position after the slight movement can be the initial position P1.

[0042] After the grouping plate 1330 returns to its original position, the blocked material continues to move forward. When it encounters the front stop X1, the front stop X1 and the rear stop X2 begin to move forward, with the moving speed consistent with the conveying channel 1200.

[0043] like Figure 10 As shown in STEP5, when the front stop X1 moves to the blocking position P5, it stops moving. At this time, the rear stop X2 just stops at the front waiting position P3, and the grouping mechanism 1300 groups a material group again. Meanwhile, the front stop S1 and the rear stop S2 are waiting at the front waiting position P3 and the rear waiting position P4.

[0044] Subsequently, the action of the lower conveying mechanism 1400 clamping and moving the material group can be referred to the action description of the upper conveying mechanism 1400 above. In this way, the two conveying mechanisms work alternately to efficiently move the material group to the transfer position.

[0045] The transfer and packing mechanism 1500 is used to transfer and pack material groups located at the transfer position.

[0046] In this embodiment, as Figure 11 As shown, the transfer and packing mechanism 1500 includes a material transfer channel 1510, a pushing unit 1520, a traversing unit 1530, a second sensor 1540, and a packing unit 1550.

[0047] The material transfer channel 1510 is arranged in a left-right direction, located to the right of the conveying channel 1200, such as... Figure 12 As shown, its inlet A is connected to the conveying channel 1200 at the transfer position, and the channel surface of the material transfer channel 1510 is flush with the conveying surface of the conveying channel 1200 in the left-right direction. Figure 12 As shown, the material transfer channel 1510 has a front baffle 1511 and a rear baffle 1512, and the distance between the two is equal to the length of the material group in the front-back direction.

[0048] The feeding unit 1520 is located on the left side of the conveying channel 1200 and is used to push the material group located at the transfer position into the material transfer channel 1510 in the left and right direction.

[0049] The feeding unit 1520 includes a docking frame 1521 and a feeding plate 1522.

[0050] The docking frame 1521 is U-shaped, lying flat with its opening facing right. It is used to move in the left-right direction under the drive of the fifth linear drive module 1523 to dock with the inlet A of the material transfer channel 1510 and to hold the material group located at the transfer position within it. The docking frame 1521 has guide grooves 1521a in the left-right direction on its front and rear sides, respectively.

[0051] The pusher plate 1522 is located inside the docking frame 1521 and is used to horizontally push the material group enclosed in the docking frame 1521 into the material transfer channel 1510 in the left-right direction under the drive of the sixth linear drive module 1524. The front and rear ends of the pusher plate 1522 are slidably engaged with the corresponding guide grooves 1521a.

[0052] The fifth linear drive module 1523 is fixed on the first frame 1525, the second frame 1526 is fixed on the first frame 1525, and the sixth linear drive module 1524 is fixed on the second frame 1526.

[0053] The transverse unit 1530 is used to horizontally push the material group pushed into the material transfer channel 1510 by the pusher unit 1520 to the box-to-pack position on the material transfer channel 1510 in the left and right direction.

[0054] In this embodiment, as Figure 12 As shown, the transverse unit 1530 includes a transverse frame 1531, a third lifting module 1532, a fourth lifting module 1533, a transverse pusher plate 1534, and a transverse baffle plate 1535.

[0055] The transverse frame 1531 is used to move horizontally in the left-right direction under the drive of the seventh linear drive module 1536. The transverse frame 1531 has a U-shaped plate 1531a. See below. Figure 13 and Figure 14 .

[0056] The third lifting module 1532 and the fourth lifting module 1533 are fixed on the left and right sides of the U-shaped plate 1531a, respectively, and are used to drive the horizontal pusher plate 1534 and the horizontal stop plate 1535 to lift.

[0057] The transverse pusher plate 1534 and the transverse baffle plate 1535 are respectively connected to the third lifting module 1532 and the fourth lifting module 1533. The transverse pusher plate 1534 is located behind the transverse baffle plate 1535 in the pushing direction, and the distance between the two is equal to the width of the material group in the left and right direction.

[0058] In this embodiment, the loading positions on the material transfer channel 1510 can accommodate three material groups spaced apart on the left and right. Correspondingly, the second sensors 1540 are photodetectors, and there are three of them. Figure 11 and Figure 12As shown, the three second sensors 1540 are all fixed on the outside of the rear baffle 1512 of the material transfer channel 1510, and the rear baffle 1512 has notches corresponding to the three second sensors 1540.

[0059] The packing unit 1550 is used to grab the material group from the packing position and pack it into a carton after all three second sensors 1540 have sensed the material group at the packing position.

[0060] In this embodiment, as Figure 15 As shown, the packing unit 1550 includes an eighth linear drive module 1551, a fifth lifting module 1552, and a gripper 1553.

[0061] The eighth linear drive module 1551 is used to horizontally drive the gripper 1553 to move between the pick-up position and the unload position in the front-back direction.

[0062] The fifth lifting module 1552 is used to drive the gripper 1553 to lift, and it is connected to the eighth linear drive module 1551 through the upper fixed plate 1551a.

[0063] The gripper 1553 is used to pick up material groups from the loading position or release material groups into the carton, such as... Figure 16 It includes a mounting plate 1553a, two first crossbeams 1553b, two sixth lifting modules 1553c, two second crossbeams 1553d, three pairs of clamps 1553e, and an upper push plate 1553f.

[0064] Mounting plate 1553a is a horizontal plate, which is connected to the fifth lifting module 1552 by bolts (and indirectly connected to the eighth linear drive module 1551). See [link / reference] Figure 15 .

[0065] Two first crossbeams 1553b are arranged at intervals in the left-right direction and are both fixed to the lower surface of the mounting plate 1553a by bolts. A connecting plate 1553g connects the two first crossbeams 1553b. (See attached image) Figure 16 .

[0066] Each first crossbeam 1553b has a hanging rail on its lower side.

[0067] The two sixth lifting modules 1553c correspond one-to-one with the two first crossbeams 1553b, and are symmetrically fixed to the outer surface of the corresponding first crossbeams 1553b by bolts.

[0068] Each of the two ends of the second crossbeam 1553d has a sliding seat on its upper surface. The two sliding seats cooperate with the hanging rails of the two first crossbeams 1553b to allow the second crossbeam 1553d to slide back and forth on the two first crossbeams 1553b.

[0069] Each second crossbeam 1553d has a ninth linear drive module 1553h on its upper surface. The two ninth linear drive modules 1553h are respectively connected and fixed to the flanges 1553g-1 formed on the front and rear edges of the connecting plate 1553g. See [reference needed]. Figure 17 It is used to drive the two second crossbeams 1553d to approach or move away from each other in the front-back direction.

[0070] Each second crossbeam 1553d is also provided with a left-right rotating shaft 1553i, such as... Figure 16 As shown, each rotating shaft 1553i is driven to rotate in the forward and backward direction by a drive source 1553j. Two clamping plates 1553e in each pair of clamping plates are symmetrically fixed to the rotating shafts 1553i of the two second crossbeams 1553d. The drive source 1553j is a linear drive source in the forward and backward direction (such as a cylinder), which is fixed to the upper surface of the corresponding second crossbeam 1553d and connected to the corresponding rotating shaft 1553i through a connecting rod 1553k.

[0071] The upper push plate 1553f is connected to two sixth lifting modules 1553c. Its vertical cross-section in the front-back direction is arched, and the front and rear edges of the upper push plate 1553f have clearance notches to avoid the clamping piece 1553e.

[0072] Based on the above description of the transfer and packing mechanism 1500, its working process is as follows: After the material handling mechanism 1400 moves the material group to the transfer position, as follows: Figure 12 , Figure 18 and Figure 19 As shown, the feeding unit 1520 first docks with the inlet A of the material transfer channel 1510 and clamps the material group. At the same time, the material group at the transfer position is detected by the sensor 1537 (photosight), causing the transverse baffle 1535 of the transverse unit 1530 to extend. Then, the feeding unit 1520 pushes the material group horizontally into the inlet A of the material transfer channel 1510.

[0073] The material group entering the material transfer channel 1510 through inlet A is stopped by the extended transverse baffle 1535. At this time, the sensor 1537 cannot detect the material group at the transfer position, which means that the material group has been pushed into inlet A. At this time, the transverse pusher 1534 of the transverse unit 1530 extends out and, together with the transverse baffle 1535, clamps the material group on the left and right sides of the material group and moves it horizontally, so that the material group moves to the boxing position.

[0074] Once the three second sensors 1540 detect that there are three material groups at the packing position, the packing unit 1550 starts to operate: First, the gripper 1553 moves horizontally from the feeding position to the picking position and then descends to the gripping position.

[0075] Then, the two ninth linear drive modules 1553h drive the two second crossbeams 1553d to approach each other in the front-back direction, so that the three pairs of clamping plates 1553e clamp the three material groups on the front and back sides. At the same time, the clamping plates 1553e swing inward under the drive of the drive source 1553j, arching the three material groups until they are held up by the upper push plate 1553f. At this time, the three material groups are all arched and firmly held, so they cannot fall off even if they shake.

[0076] Finally, the gripper 1553 retracts carrying the three material groups and moves horizontally to the unloading position before descending to the release position. Upon reaching the release position, the gripper 1553 releases the material groups into the carton. Simultaneously, the upper push plate 1553f descends to push the material groups, ensuring that the materials remain flat after entering the carton.

[0077] In this embodiment, each linear drive module uses an electric cylinder or a pneumatic cylinder.

[0078] As can be seen from the above, the packing and conveying device provided in this application embodiment can automatically group and pack the plate-shaped materials output by the gluing machine, reducing the labor intensity of workers and improving production efficiency. At the same time, when grouping, the grouping mechanism first uses an elastic sheet to widen the gap between the grouping mark material and the previous material, and then inserts a grouping insert plate between the grouping mark material and the previous material to avoid damage to the paper material by the grouping insert plate.

[0079] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
