Description

Technical Field

[0001] This invention relates to a spout bag assembly device, and more specifically to a rotary spout bag welding machine that can quickly and accurately push out spout bags from a turntable, arrange them in sequence, and then feed them into another turntable in sequence. Background Technology

[0002] Currently, the production of spout pouches is usually completed using a bag-making production line. The spout pouches produced by the production line are then transported to the packaging site by transportation equipment. The equipment then feeds the spout pouches into the packaging machine for filling, and finally, a sealing cap is installed to obtain the finished spout pouch packaging product.

[0003] However, this production method is problematic because the finished spout pouches are difficult to sort and stack. The bag production line needs to sort the finished spout pouches, hang them on rods for storage and transport, and then send the rods to the packaging machine. A special bag feeding mechanism for the rods is then used to feed the pouches into the packaging machine. This results in excessive equipment and processing steps, high logistics and production costs, and low work efficiency, making it difficult to meet the needs of large-scale industrial production. Furthermore, the hygiene of the rods is difficult to guarantee during the production, transportation, storage, and transfer of the spout pouches, which in turn makes it difficult to ensure the hygiene of the spout pouches. This negatively impacts the quality of the finished packaged spout pouches (i.e., spout pouches containing materials and sealed with a cap).

[0004] To address this, the applicant improved upon the traditional technology by first bagging the nozzle and the nozzle bag (with an installation opening at the top) together, and then sealing the connection between the nozzle and the nozzle bag at at least one point to obtain a semi-finished nozzle bag. This semi-finished nozzle bag is then fed into a sealing unit for sealing to obtain the finished nozzle bag. Furthermore, the applicant sets up the processing equipment for the semi-finished nozzle bags on a single intermittently moving turntable, the processing for obtaining the finished nozzle bag on a second intermittently moving turntable, and the filling and packaging equipment on a third intermittently moving turntable. Therefore, existing bag-pushing devices are insufficient to meet the requirements of accurately transferring nozzle bags between adjacent turntables in a production line consisting of three turntables, leading to potential transfer failures and low efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a rotary spout bag welding machine that can quickly and accurately push out, arrange, and sequentially feed spout bags from one rotary table to another. The technical solution adopted is as follows: A rotary spout bag welding machine includes a rotary table, a first driving component, a rotary table transmission mechanism, a cam divider, a spout bag ejection mechanism, and a support plate mounted on the frame of the rotary table spout bag welding production line. The first driving component, the rotary table transmission mechanism, the cam divider, and the spout bag ejection mechanism are respectively mounted on the top surface of the support plate. The first driving component is connected to the input shaft of the cam divider through the rotary table transmission mechanism. The rotary table is mounted on the vertically upward-extending output shaft of the cam divider. The rotary table has an ejection station, and the spout bag ejection mechanism is located below the ejection station of the rotary table. The edge of the rotary table has multiple spout hanging groove groups, each of which has multiple spout hanging grooves. The spout bag ejection mechanism includes... The bag pushing unit simultaneously pushes out multiple nozzle bags from the same nozzle suspension slot group that is suspended on the edge of the turntable at the ejection station; The packaging bag conversion and conveying unit receives multiple spout bags pushed out by the aforementioned bag pushing unit, arranges them in sequence in a row, and then sends them out. The multi-bag transfer unit uses a transfer channel to receive multiple spout bags and delivers them to a transfer area at the front of the transfer channel where a turntable for receiving spout bags can automatically scrape them away. This spout bag ejection mechanism sequentially feeds all spout bags (multiple) from the spout hanging slots at one station on the edge of the turntable into and out of the transfer channel, allowing the receiving turntable to automatically pick up these spout bags sequentially and suspend them in the surrounding spout clamping slots.

[0006] In a preferred embodiment, the bag pushing unit includes a second driving component, a first horizontal push rod, a horizontal moving positioning plate, and multiple suction bag pushing components. The horizontal moving positioning plate is mounted on the frame of the rotary suction bag welding production line, which can move horizontally along the pushing direction (radial direction of the turntable). The second driving component is mounted on the frame of the rotary suction bag welding production line. The first horizontal push rod is hinged to the second driving component and the horizontal moving positioning plate at both ends, and the multiple suction bag pushing components are respectively mounted on the horizontal moving positioning plate.

[0007] An even better solution is to have the same number of nozzle bag pushers as the number of nozzle suspension slots in the same nozzle suspension slot group.

[0008] A better embodiment is that the suction bag pusher includes a pusher frame and a cylinder. The cylinder is fixed on the rear side of the horizontally moving positioning plate, and the piston shaft of the cylinder extends horizontally in the direction of the inner side of the turntable (radial direction of the turntable) and is connected to the pusher frame.

[0009] In a better configuration, the movement trajectory of the pusher frame is aligned with the movement trajectory of the horizontally moving positioning plate. During operation, the second drive unit moves the horizontally moving positioning plate towards the outside of the turntable, while the cylinder drives the pusher frame towards the inside of the turntable. When a spout bag has a quality problem (i.e., the testing agency detects that the spout bag's airtightness does not meet the requirements and it is unqualified), and it is a waste bag, the cylinder of the corresponding spout bag pusher component moves the pusher frame towards the inside of the turntable, and the distance of movement is the same as the distance of movement of the horizontally moving positioning plate. The cylinders of the spout bag pushers for other spout bags remain stationary, preventing the waste bag from being pushed out, while other spout bags (that pass the inspection) are pushed out and sent to the packaging bag conversion and conveying unit.

[0010] In a preferred embodiment, the packaging bag transfer and conveying unit includes a first movable intermediate bag receiving plate, a second movable intermediate bag receiving plate, a first bag receiving plate lateral moving component, a second bag receiving plate lateral moving component, a first lever for pulling out and sending the spout bag into the multi-packaging bag transfer unit, and a first lever drive rod. The first movable intermediate bag receiving plate is laterally movable and mounted on the frame. The first movable intermediate bag receiving plate has multiple first spout bag hanging and positioning slots. The second movable intermediate bag receiving plate is laterally movable and mounted on the frame. The second movable intermediate bag receiving plate has a second spout bag hanging and positioning slot and is in close contact with the first movable intermediate bag receiving plate. The first bag receiving plate lateral moving component drives the first movable intermediate bag receiving plate to move laterally, and the second bag receiving plate lateral moving component drives the second movable intermediate bag receiving plate to move laterally. The first lever is mounted on the frame and can move toward the entrance of the multi-packaging bag transfer unit. The first lever drive rod is hinged to the first lever and drives the first lever to move.

[0011] A better solution is that the number of the first nozzle bag suspension positioning slots is two, and each nozzle suspension slot group of the turntable has two nozzle suspension slots.

[0012] A better solution is that the packaging bag conversion and conveying unit has a distribution state and a sorting and pushing state. In the distribution state, the first bag receiving plate lateral movement component drives the first movable intermediate bag receiving plate to move laterally until the two first suction bag hanging positioning slots move to the pushing station and correspond one-to-one with the two suction bag hanging slots of a suction bag hanging slot group located on the edge of the turntable at the pushing station, and they are connected to each other. At the same time, the second bag receiving plate lateral movement component drives the second movable intermediate bag receiving plate to move laterally and connects the second suction bag hanging positioning slot with a first suction bag hanging positioning slot. Then the bag pushing unit suspends the two suction bags. The suction bags in the hanging slots are simultaneously pushed out and delivered to the second suction bag hanging positioning slot and the first suction bag hanging positioning slot. In the sorted push-out state, the first bag receiving plate lateral movement component drives the two first suction bag hanging positioning slots to move laterally, while the second bag receiving plate lateral movement component drives the second movable middle bag receiving plate to move laterally until the second suction bag hanging positioning slot with the suction bag, the first suction bag hanging positioning slot with the suction bag, and the multi-packaging bag transfer unit entrance are connected. The first lever drive rod drives the first lever to move, sequentially pushing out the two suction bags and sending them into the multi-packaging bag transfer unit entrance.

[0013] In a preferred embodiment, the multi-packaging bag transfer unit further includes a second lever, a second lever lifting component, and a second lever drive component. The transfer channel is fixed on the frame, and the rear entrance of the transfer channel receives the nozzle bag. The front part of the transfer channel is a transfer area that coincides with the movement trajectory of the nozzle clamping groove located on the edge of the turntable receiving the nozzle bag. The second lever drive component is mounted on the frame, the second lever lifting component is mounted on the second lever drive component, and the second lever is mounted on the second lever lifting component. The second lever drive component drives the second lever lifting component and the second lever to move along the rear part of the transfer channel. The second lever lifting component drives the second lever to rise and fall, so that the second lever inserts into or leaves the rear part of the transfer channel.

[0014] In a preferred embodiment, the nozzle bag ejection mechanism further includes a forced-displacement unit, which includes a third driving component, a second horizontal push rod, and a forced-displacement frame. The forced-displacement frame is horizontally mounted on the frame of the rotary nozzle bag welding production line and can move horizontally along the pushing direction (radial direction of the turntable). The third driving component is mounted on the frame and is connected to the forced-displacement frame through the second horizontal push rod, thereby driving the forced-displacement frame to move.

[0015] In one embodiment, the second driving component, the first bag receiving plate lateral moving component, the second bag receiving plate lateral moving component, the first lever driving rod, and the third driving component are all selected as independent driving devices.

[0016] In another embodiment, the spout bag ejection mechanism further includes an ejection mechanism transmission unit. This transmission unit is connected to a turntable transmission mechanism and provides power to the bag pushing unit, the packaging bag conversion and conveying unit, and / or the forced-displacement unit. The ejection mechanism transmission unit obtains power from the first driving component through the turntable transmission mechanism and supplies it to the bag pushing unit, the packaging bag conversion and conveying unit, and the forced-displacement unit. This saves on driving devices, simplifies the structure, and enables automatic control of all or part of the actions of each unit.

[0017] A better embodiment is that the push mechanism transmission unit includes a first cam linkage transmission mechanism and a second cam linkage transmission mechanism. The first cam linkage transmission mechanism is connected to the bag pushing unit and the forced discharge unit respectively and drives the bag pushing unit and the forced discharge unit to move. The second cam linkage transmission mechanism is connected to the packaging bag conversion and conveying unit and drives the packaging bag conversion and conveying unit to move.

[0018] The advantages of this invention compared to the prior art are that, because the bag pushing unit, packaging bag conversion and conveying unit, and multi-packaging bag transfer unit of the spout bag ejection mechanism can cooperate with each other, it can automatically, quickly, and accurately eject spout bags from the turntable, arrange them, and then send them sequentially to another turntable, resulting in high work efficiency. Furthermore, the ejection mechanism transmission unit can use the turntable's drive device to replace the drive devices of each unit, greatly reducing the number of drive devices, effectively saving energy, and significantly reducing manufacturing and production costs. The entire spout bag ejection device has a reasonable structure and precise coordination between its components, enabling it to effectively transport spout bags from one turntable to another.

Detailed Implementation

[0020] like Figure 1-9 As shown, a rotary nozzle bag welding machine according to one embodiment of this application includes a first rotary table 1, a first driving component 2, a rotary table transmission mechanism 3, a cam divider 4, a nozzle bag ejection mechanism 5, and a support plate 6 mounted on a frame (not shown) of a rotary table nozzle bag welding production line. The first driving component 2, the rotary table transmission mechanism 3, the cam divider 4, and the nozzle bag ejection mechanism 5 are respectively mounted on the top surface of the support plate 6. The first driving component 2 is connected to the input shaft of the cam divider 4 through the rotary table transmission mechanism 3. The first rotary table 1 is mounted on the vertically upward-extending output shaft of the cam divider 4. The first rotary table 1 has an ejection station, and the nozzle bag ejection mechanism 5 is located below the ejection station of the first rotary table 1. The edge of the first rotary table 1 has multiple nozzle suspension slot groups 101, each nozzle suspension slot group 101 having two nozzle suspension slots 1011. The first driving component 2 is a servo motor. The rotary table transmission mechanism 3 is a gear set.

[0021] The spout bag ejection mechanism 5 includes The bag pushing unit 501 simultaneously pushes out two nozzle bags located at the ejection station and suspended in the same nozzle suspension groove 101 on the edge of the first turntable 1. The packaging bag conversion and conveying unit 502 receives the two spout bags pushed out by the bag pushing unit 501 and arranges them in a row in sequence before sending them out. The multi-packaging bag transfer unit 503 uses a transfer channel 5031 to receive the two spout bags and transfer multiple packaging bags (two spout bags can be pushed forward immediately, or four or more spout bags can be collected before pushing to reduce the number of actions and save energy) to the transfer area 50311 at the front of the transfer channel 5031, where the second turntable 7 that receives spout bags can automatically scrape them away. With such a spout bag ejection mechanism 5, all spout bags (multiple) in the spout hanging slots 1011 on one station (ejection station) at the edge of the first turntable 1 can be sequentially fed into and out of the transfer channel 5031, allowing the second turntable 7 that receives spout bags to automatically pick up these spout bags sequentially and suspend them in the spout clamping slots around them.

[0022] The bag pushing unit 501 includes a second driving component, a first horizontal push rod 5011, a horizontal moving positioning plate 5012, and two suction bag pushing components 5013. The horizontal moving positioning plate 5012 is horizontally mounted on the frame of the rotary suction bag welding production line, which can move horizontally along the pushing direction (radial direction of the first turntable 1). The second driving component is mounted on the frame of the rotary suction bag welding production line. The two ends of the first horizontal push rod 5011 are respectively hinged to the second driving component and the horizontal moving positioning plate 5012. The two suction bag pushing components 5013 are respectively mounted on the horizontal moving positioning plate 5012.

[0023] In an alternative embodiment, the spout bag pusher 5013 includes a pusher frame 50131 and a first cylinder 50132. The first cylinder 50132 is fixed on the rear side of the horizontally movable positioning plate 5012. The piston shaft of the first cylinder 50132 extends horizontally in the direction of the inner side of the first turntable 1 (radial direction of the first turntable 1) and is connected to the pusher frame 50131.

[0024] In an alternative embodiment, the movement trajectory of the pusher 50131 is on the same straight line as the movement trajectory of the horizontal moving positioning plate 5012. During operation, the second driving member drives the horizontal moving positioning plate 5012 to move outward toward the first turntable 1, while the first cylinder 50132 drives the pusher 50131 to move inward toward the first turntable 1. When the quality of the spout bag is problematic (i.e., the testing agency detects that the airtightness of the spout bag does not meet the requirements and it is unqualified), it is a waste bag. The first cylinder 50132 of the spout bag pusher 5013 corresponding to the waste bag drives the pusher 50131 to move inward toward the first turntable 1, and the distance of movement is the same as the distance of movement of the horizontal moving positioning plate 5012. The first cylinder 50132 of the spout bag pusher 5013 corresponding to other spout bags does not move, so that the waste bag is not pushed out, while other spout bags (which pass the test) are pushed out and sent to the packaging bag conversion conveying unit 502.

[0025] The packaging bag transfer and conveying unit 502 includes a first movable intermediate bag receiving plate 5021, a second movable intermediate bag receiving plate 5022, a first bag receiving plate lateral moving component 5023, a second bag receiving plate lateral moving component 5024, a first lever 5025 for pushing out and sending the spout bag into the multi-packaging bag transfer unit 503, and a first lever drive rod 5026. The first movable intermediate bag receiving plate 5021 is laterally movable and mounted on the frame. The first movable intermediate bag receiving plate 5021 has two first spout bag hanging positioning slots 50211. The second movable intermediate bag receiving plate 5022 is laterally movable and mounted on the frame. The second movable intermediate bag-connecting plate 5022 has a second suction bag hanging positioning groove 50221, and the second movable intermediate bag-connecting plate 5022 is closely attached to the first movable intermediate bag-connecting plate 5021. The first bag-connecting plate lateral moving member 5023 drives the first movable intermediate bag-connecting plate 5021 to move laterally, and the second bag-connecting plate lateral moving member 5024 drives the second movable intermediate bag-connecting plate 5022 to move laterally. The first lever 5025 is mounted on the frame and can move toward the entrance of the multi-packaging bag transfer unit 503. The first lever drive rod 5026 is hinged to the first lever 5025 and drives the first lever 5025 to move.

[0026] In an alternative embodiment, the packaging bag conversion and conveying unit 502 has a distribution state and a sorting and pushing state. In the distribution state, the first receiving plate lateral movement member 5023 drives the first movable intermediate receiving plate 5021 to move laterally until the two first suction bag hanging positioning slots 50211 move to the pushing station and correspond one-to-one with the two suction bag hanging slots 1011 of a suction bag hanging slot group 101 located on the edge of the first turntable 1 at the pushing station, and they are connected to each other. At the same time, the second receiving plate lateral movement member 5024 drives the second movable intermediate receiving plate 5022 to move laterally and connects the second suction bag hanging positioning slot 50221 with one of the first suction bag hanging positioning slots 50211. Then the bag pushing unit 501 pushes the two suction bag hanging slots... The 1011 spouts are simultaneously pushed out and placed into the second spout hanging positioning slot 50221 and the first spout hanging positioning slot 50211. In the sorted push-out state, the first receiving plate lateral movement member 5023 drives the two first spout hanging positioning slots 50211 to move laterally, and at the same time, the second receiving plate lateral movement member 5024 drives the second movable intermediate receiving plate 5022 to move laterally until the second spout hanging positioning slot 50221 with the spout, the first spout hanging positioning slot 50211 with the spout, and the entrance of the multi-packaging bag transfer unit 503 are connected. The first lever drive rod 5026 drives the first lever 5025 to move, and pushes out the two spouts in sequence and puts them into the entrance of the multi-packaging bag transfer unit 503.

[0027] like Figure 1 , 4As shown in Figure 5, in an alternative embodiment, the multi-packaging bag transfer unit 503, in addition to the aforementioned transfer channel 5031, also includes a second lever 5032, a second lever lifting component 5033, and a second lever driving component 5034. The transfer channel 5031 is fixed on the frame. The rear inlet of the transfer channel 5031 (i.e., the inlet of the aforementioned multi-packaging bag transfer unit 503) receives the spout bags. The front of the transfer channel 5031 is a transfer path that coincides with the movement trajectory of the spout clamping groove located on the edge of the second turntable 7 that receives the spout bags. In section 50311, the second lever drive 5034 is mounted on the frame, the second lever lifting component 5033 is mounted on the second lever drive 5034, and the second lever 5032 is mounted on the second lever lifting component 5033. The second lever drive 5034 drives the second lever lifting component 5033 and the second lever 5032 to move along the rear of the transfer channel 5031. The second lever lifting component 5033 drives the second lever 5032 to rise and fall, causing the second lever 5032 to insert into or leave the rear of the transfer channel 5031. The second lever drive 5034 is a cylinder.

[0028] In an alternative embodiment, the multi-bag transfer unit 503 further includes a spring, with both ends of the spring connected to the frame and the second lever 5032. In this embodiment, the tension of the spring drives the second lever 5032 forward, pushing the spout bag forward, while the second lever drive member 5034 is used to return the second lever 5032 to the rear of the transfer channel 5031.

[0029] In an alternative embodiment, the nozzle bag ejection mechanism 5 further includes a forced-displacement unit 504, which includes a third drive member, a second horizontal push rod 5042, and a forced-displacement frame 5041. The forced-displacement frame 5041 is horizontally mounted on the frame of the rotary nozzle bag welding production line along the pushing direction (radial direction of the first turntable 1). The third drive member is mounted on the frame and is connected to the forced-displacement frame 5041 through the second horizontal push rod 5042, thereby driving the forced-displacement frame 5041 to move.

[0030] In one alternative embodiment, the second drive member, the first bag-receiving plate lateral movement member 5023, the second bag-receiving plate lateral movement member 5024, the first lever drive rod 5026, and the third drive member are all selected with independent drive devices. In this embodiment, the drive device is a cylinder. Other reciprocating motion mechanisms can also be selected.

[0031] like Figure 1As shown, in an alternative embodiment, the spout bag ejection mechanism 5 further includes an ejection mechanism transmission unit 505. The ejection mechanism transmission unit 505 is connected to the turntable transmission mechanism 3 via a gear set 8 and provides power to the bag pushing unit 501, the packaging bag conversion and conveying unit 502, and the forced discharge unit 504, respectively. The ejection mechanism transmission unit 505 obtains power from the first driving member 2 through the turntable transmission mechanism 3 and provides it to the bag pushing unit 501, the packaging bag conversion and conveying unit 502, and the forced discharge unit 504, thereby saving on driving devices, simplifying the structure, and enabling automatic control of all or part of the actions of each unit.

[0032] In an alternative embodiment, the ejection mechanism transmission unit 505 includes a first cam-linkage transmission mechanism 5051 and a second cam-linkage transmission mechanism 5052. The first cam-linkage transmission mechanism 5051 is connected to the bag pushing unit 501 and the forced discharge unit 504 respectively, and drives the bag pushing unit 501 and the forced discharge unit 504 to move respectively. The second cam-linkage transmission mechanism 5052 is connected to the packaging bag conversion and conveying unit 502 and drives the packaging bag conversion and conveying unit 502 to move. Therefore, the second driving member, the first bag receiving plate lateral moving member 5023, the second bag receiving plate lateral moving member 5024, the first lever driving rod 5026, and the third driving member are all replaced by the linkages of the ejection mechanism transmission unit 505 or connected to the driving components of the ejection mechanism transmission unit 505.

[0033] like Figure 1 As shown, in an alternative embodiment, the first cam-linkage transmission mechanism 5051 includes a first cam 50511, a first rocker arm 50512, a first connecting rod 50513, a second rocker arm 50514, a first rotating shaft 50515, a first triangular connecting rod 50516, a second connecting rod 50517, and a second triangular connecting rod 50518. The first triangular connecting rod 50516 replaces the second driving member, and the second triangular connecting rod 50518 replaces the third driving member.

[0034] like Figure 1As shown, in an alternative embodiment, the second cam-linkage transmission mechanism 5052 includes a first cam-linkage transmission unit 50521 and a second cam-linkage transmission unit 50522. The first cam-linkage transmission unit 50521 includes a second cam 505211, a second rocker arm 505212, a third link 505213, and a third rocker arm 505214. The third rocker arm 505214 is hinged to the frame in the middle, and its two ends are respectively hinged. The first receiving plate transverse moving component 5023 and the second receiving plate transverse moving component 5024; the second cam linkage transmission unit 50522 includes a third cam 505221, a fourth rocker arm 505222, a fourth connecting rod 505223, a sixth rocker arm 505224, a second rotating shaft 505225, a seventh rocker arm 505226, a third rotating shaft 505227, and an eighth rocker arm 505228, the eighth rocker arm 505228 being connected to the first lever drive rod 5026.

[0035] The following is combined with Figure 1-9 Let me introduce the work process: The push mechanism transmission unit 505 drives the receiving and pushing bag unit 501, the packaging bag conversion and conveying unit 502, and the forced discharge unit 504 to operate.

[0036] Turntable 1 rotates intermittently. When turntable 1 stops, a suction nozzle suspension groove 101 on its edge is located at the ejection station.

[0037] First, the bag pushing unit 501 pushes out the two mouthpiece bags in the above-mentioned mouthpiece hanging slot group 101 at the same time, and the forced discharge unit 504 also works. Then, the packaging bag conversion and conveying unit 502 receives the two spout bags pushed out by the bag pushing unit 501 and arranges them in a row in sequence before sending them out (if the detection device of the rotary spout bag welding machine detects that one of the two spout bags is defective, the spout bag pusher 5013 corresponding to that spout bag will work when the horizontal moving positioning plate 5012 moves forward and drive the pusher frame 50131 to move backward, so that the spout bag will not be pushed out). Next, the transfer channel 5031 of the multi-packaging bag transfer unit 503 receives the two spout bags mentioned above, and after accumulating four bags, pushes them forward to the transfer area 50311 at the front of the transfer channel 5031, where the second turntable 7 that receives spout bags can automatically scrape them away. With such a spout bag ejection mechanism 5, all spout bags (multiple) in the spout hanging slots 1011 on one station (ejection station) at the edge of the first turntable 1 can be sequentially fed into the transfer channel 5031 and ejected, allowing the second turntable 7 that receives spout bags to automatically pick up these spout bags sequentially and suspend them in the spout clamping slots around them.

[0038] Finally, turntable 1 rotates intermittently, with the nozzle suspension slot assembly 101 rotating to the forced discharge unit 504, and the next nozzle suspension slot assembly 101 rotating to the ejection station. This cyclical operation continuously feeds the nozzle bag out for the second turntable 7 to automatically scrape it away. Meanwhile, the forced discharge unit 504 discharges the waste products during operation.

[0039] Furthermore, it should be noted that the names of the various parts of the specific embodiments described in this specification may differ. All equivalent or simple variations made to the structure, features, and principles described in this invention are included within the scope of protection of this invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this invention or exceed the scope defined in these claims, all of which should fall within the scope of protection of this invention.
