Description

Technical Field

[0001] The invention relates to the technical field of assembly lines, and in particular to a multi-stage assembly line for factory processing and an operation method thereof. Background Art

[0002] In the modern food industrial processing industry, large-scale processing plants have a huge throughput for agricultural product processing. Ordinary factories process farm products in two steps, namely manual processing and equipment processing. One reason for manual processing is the lack of equipment, and some processes such as sorting are difficult to complete perfectly with equipment. Therefore, some factories will still set up a manual sorting and pre-processing before equipment processing. Of course, some factories still use the method of full manual assembly line processing and only use equipment for packaging and other operations in the final stage.

[0003] The existing agricultural product processing lines are generally relatively simple, such as Figure 1 In the circular assembly line or the simpler straight assembly line, workers sit upright at their workstations, which are set on one side of the assembly line. The assembly line drives agricultural products past the workers' workstations. The operating workers need to grab the agricultural products from the assembly line, and then put them back to the original assembly line or a specific assembly line or temporarily store them in the finished product frame after processing. The assembly line provides a relatively simple conveying function. Under the above-mentioned method, taking and putting materials on the assembly line invisibly increases the workload and improves the work intensity. Similarly, putting them into the second assembly line and the finished product frame is the same. Moreover, the method of setting up the finished product frame is quite unsuitable for some multi-step division of labor processing processes, which will cause repeated transportation problems. Moreover, when the workers' efficiency cannot keep up with the above-mentioned existing simple assembly line conveyor belt, the products to be processed will continue to circulate on the assembly line until they are taken down by the operating staff. When multiple employees are located on the same assembly line, there will be a problem that the front takes away the processed raw materials and the employees at the back have nothing to do.

[0004] Based on the above-mentioned problems of the assembly line, there is a need for a more mature assembly line that is suitable for multi-stage processing of agricultural products, which can meet and solve the various shortcomings of the existing technology and meet the factory's processing process requirements for agricultural products including marine crops. Summary of the invention

[0005] In view of the prior art, an object of the present invention is to provide an assembly line device that can flexibly meet the needs of agricultural product processing and a method of using the same.

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: a multi-stage production line for factory processing, including an annular raw material conveying line, the annular raw material conveying line includes an annular conveying belt, and a plurality of raw material bearing members fixedly installed on the conveying belt;

[0008] A feeding conveyor line and a finished product conveyor line, wherein the feeding conveyor line and the finished product conveyor line are arranged side by side and connected to the annular raw material conveyor line, and the inlet and outlet ends of the station conveyor belt are respectively connected to the annular raw material conveyor line;

[0009] A control system, the control system comprising a plurality of sensing units and a control switch, the control switch being located at a working position of a workstation conveyor belt, the sensing unit being used to scan a barcode located on a raw material carrier;

[0010] The conveyor belt is also provided with a plurality of side push devices which are triggered by control and are used to push the raw material carrier;

[0011] The side push device includes a power cylinder and a push arm, and the push arm is arranged directly opposite to the raw material carrier;

[0012] A set of side pushing devices for pushing the raw material carrier to flow to the next assembly line are provided at the connection between the annular raw material conveyor line and the workstation conveyor belt, the connection between the annular raw material conveyor line and the finished product conveyor line, and the connection between the loading conveyor line and the annular raw material conveyor line.

[0013] As a further configuration of the above scheme, the sensing unit includes a loading sensor located on the circular raw material conveyor line relative to its connection with the workstation conveyor belt for reading the material status information of the raw material carrier, and an infrared sensor located at the connection between the finished product conveyor line and the workstation conveyor belt and at the connection between the circular raw material conveyor line and the loading conveyor line for determining whether there are raw material carriers at corresponding positions.

[0014] As a further configuration of the above scheme, a lifting workbench is provided at the work position, and a high-frequency oscillation device is provided on the lifting workbench, and the high-frequency oscillation device is used to evenly disperse the products in the raw material carrier.

[0015] As a further configuration of the above scheme, a loading platform is arranged on the annular raw material conveying line, each loading platform corresponds to a raw material carrier, and the number of raw material carriers circulating on the annular raw material conveying line and the workstation conveyor belt is greater than the total number of loading platforms of the annular raw material conveying line.

[0016] As a further arrangement of the above scheme, the side walls of the annular raw material conveyor line facing the side thrust device are provided with side thrust steps, the support platform is provided with guide wheels at the four corners relative to the raw material support member, and the annular raw material conveyor line, the work station conveyor belt, the loading conveyor line and the finished product conveyor line are provided with guide angles matching the guide wheels at corresponding locations.

[0017] The present invention also provides a method for operating a multi-stage assembly line for factory processing, comprising the following steps:

[0018] S1: With the assistance of external employees, the circular raw material conveyor line is uniformly loaded with materials, and the process of raw materials is entered into the control system;

[0019] S101: The control system reads the barcode of the raw material carrier based on the sensing unit and enters the preset current state of the material into the database;

[0020] S2: After the worker enters the corresponding process station conveyor belt, he selects the corresponding operation process and the working station conveyor belt number in the control system. The linkage feeding sensor of the station conveyor belt reads the raw material carrier code on the circular raw material conveyor line and feeds the material through the side push device;

[0021] S201: After the operator enters the workstation conveyor belt and officially starts working, he selects the processing procedure by operating the control system on the current workstation conveyor belt. The control system sends the worker's working procedure to the main server, and the control system integrates the worker's process technology and calculates to ensure uniform flow distribution;

[0022] S202: At this time, the circular raw material conveyor line is already in circulation, and the sensing unit of the current station scans the raw material carrier passing by and continuously compares it with the processing steps of the conveyor belt of the current station;

[0023] S203: When the raw material carrier corresponds to the processing step, the control system controls the side push device to start, the power cylinder drives the push arm to extend, pushes the raw material carrier into the waiting seat of the workstation conveyor belt, and then the push arm is reset;

[0024] S3: After the workstation conveyor belt is loaded, the stepper motor drives the workstation conveyor belt to move, and the raw material carrier is transferred between the waiting seat, the working seat and the finishing seat, and waits at the finishing seat to be sent back to the circular raw material conveying line by the side push device;

[0025] S301: After the raw material carrier is pushed into the workstation conveyor belt by the side push device on the circular raw material conveyor line, it will enter the waiting seat first. At this time, if there is no raw material on the workstation, the stepper motor of the driving unit of the workstation conveyor belt will start to send the raw material carrier on the waiting seat to the workstation;

[0026] S302: When there is no raw material carrier on the waiting seat, the sensing unit of the control system will feedback a signal. When the feeding sensor detects that the raw material carrier passing by meets the feeding requirement, the side push device will be immediately started to fill the position;

[0027] S303: When the worker finishes processing the raw materials in the raw material carrier on the working position and presses the control switch, the stepper motor starts again to transport the raw material carrier on the waiting seat to the working position, and at the same time, the raw material carrier on the working position moves backward to the finishing seat;

[0028] S304: When the infrared sensor of the circular material conveyor line detects an empty position, the side pusher arranged at the completion seat side is activated to push the material carrier into the circular material conveyor line to complete the processing;

[0029] S4: After the raw material carrier passes through the workstation conveyor belt, the processing information of the raw material carried on the barcode of the raw material carrier in the database of the control system is updated according to the processing steps of the current workstation process when the control switch is pressed. After it flows to the workstation conveyor belt of the next corresponding process, the side push device is triggered to push it into the loading according to whether the waiting seat on the corresponding workstation conveyor belt is vacant;

[0030] S5: The upper and lower raw material carriers of the loading conveyor line and the finished product conveyor line are set to act in correspondence. When the sensing unit arranged on the annular raw material conveyor line reads that the raw material in the raw material carrier is processed, when it reaches the finished product conveyor line, the corresponding side push device is started to push it out of the annular raw material conveyor line and into the finished product conveyor line. At the same time, the loading conveyor line located behind it pushes the raw material carrier containing new raw materials into the annular raw material conveyor line.

[0031] As a further arrangement of the above scheme, an off-position switch is also provided on the work station, and the off-position switch is used to be triggered after the operator leaves the work station conveyor belt. The control system sends a command to start the stepper motor to return the unfinished processed raw material carrier on the work station conveyor belt to the annular raw material conveyor line 1, and closes the loading sensor and side thrust device of the corresponding work station conveyor belt.

[0032] Beneficial effects: The assembly line structure of the present invention is based on the deficiencies of the prior art, and improves the processing efficiency by optimizing the flow mode of the assembly line. The assembly line structure scheme of the present invention can ignore the arrangement of the process positions, and can flexibly adjust the processing operations of the workers' processes according to the flow of the process. The setting of waiting seats, etc. can facilitate the flow of materials for workers and improve work efficiency. In addition, it can effectively avoid the problem that the downstream process cannot be carried out due to accumulation at a certain place during the process flow;

[0033] In addition, the multi-stage assembly line used in the factory processing of this embodiment can improve the operating standards. During the process flow, information is updated through barcodes, and the person in charge can also trace the source based on the barcodes to know the processing number, personnel and processing status of each process, ensuring that each process is clear.

[0039] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0040] like Figure 2-4A multi-stage assembly line for factory processing is shown, and the assembly line structure of the present invention includes a main annular raw material conveying line 1. The annular raw material conveying line 1 of this embodiment includes an annular conveyor belt 10, a plurality of raw material carriers 5 fixedly installed on the conveyor belt 10; a station conveyor belt 4, wherein a plurality of station conveyor belts 4 are arranged relative to the annular raw material conveying line 1, and each of the station conveyor belts 4 is provided with a waiting seat 12, a working position 13 and a finishing seat 14, a loading conveyor line 9 and a finished product conveyor line 3, wherein the loading conveyor line 9 and the finished product conveyor line 3 are arranged side by side and connected to the annular raw material conveying line 1, and the inlet and outlet ends of the station conveyor belt 4 are respectively connected to the annular raw material conveying line 1; a control system, wherein the control The system includes a plurality of sensing units 6 and a control switch 7, wherein the control switch 7 is located at the working position 13 of the workstation conveyor belt 4, and the sensing unit 6 is used to scan the barcode located on the raw material carrier 5; the conveyor belt 10 is also provided with a plurality of side pushing devices 8 which are triggered by control to push the raw material carrier 5; the side pushing device 8 includes a power cylinder 81 and a push arm 82, and the push arm 82 is arranged directly opposite to the raw material carrier 5; a group of side pushing devices 8 for pushing the raw material carrier 5 to flow to the next assembly line are all provided at the connection between the annular raw material conveyor line 1 and the workstation conveyor belt 4, the connection between the annular raw material conveyor line 1 and the finished product conveyor line 3, and the connection between the loading conveyor line 9 and the annular raw material conveyor line 1.

[0041] As described above, the assembly line of the present invention is provided with a relatively long circular raw material conveying line 1 to circulate and transport raw materials, semi-finished products and finished products, and is provided with a plurality of workstation conveyor belts 4 connected to the circular raw material conveying line 1. Workers are located at the workstation conveyor belts 4, and the supply and unloading of raw materials are realized through the cooperation of the sensing unit 6 of the control system and various driving structures including the side thrust device 8;

[0042] The side push device 8 connected to the control unit has a simple structure, and is composed of a power cylinder 81 and a push arm 82. The power cylinder 81 can be a commercially available air cylinder, hydraulic cylinder, electric cylinder, etc., and its purpose is to drive the push arm 82 to extend and retract to push the raw material carrier 5 to a set position.

[0043] The control unit is also connected to a sensing unit 6, which includes but is not limited to a feeding sensor 61 and an infrared sensor 62 of the present embodiment. It is worth noting that the feeding sensor 61 is configured as a machine vision camera assembly for quickly photographing and scanning a barcode, and triggering the status information in the control system database through the barcode, so that the control system quickly obtains the raw material status information in the current raw material carrier 5, thereby quickly determining whether to perform an operation such as starting the side thrust device 8. The setting of the infrared sensor 62 includes but is not limited to the position mentioned in the present invention, and its main function is to provide the control system of the assembly line with information on whether there is a raw material carrier 5 at the current position. When setting up the assembly line, multiple components can be set or replaced with other functional components according to actual needs and sensing sensitivity;

[0044] As a further configuration of the above scheme, the sensing unit 6 includes a loading sensor 61 located on the annular raw material conveyor line 1 relative to the connection between it and the workstation conveyor belt 4 for reading the material status information of the raw material carrier 5, and an infrared sensor 62 located at the connection between the finished product conveyor line 3 and the workstation conveyor belt 4 and on the annular raw material conveyor line 1 relative to the connection between it and the loading conveyor line 9 for determining whether there is a raw material carrier 5 at the corresponding position.

[0045] As a further arrangement of the above scheme, a lifting workbench is provided at the work station 13, and a high-frequency oscillation device is provided on the lifting workbench. The high-frequency oscillation device is used to evenly disperse the products in the raw material carrier 5. It is worth noting that what is not clearly drawn in the figure is that the main structure of the work station conveyor belt 4 of this embodiment is divided into three parts, the waiting seat 12, the work station 13 and the completion seat 14. On the basis of the above three, they are connected by setting a ring-shaped conveyor belt structure. It is worth noting that the conveyor belt is connected on both sides with a middle hollow. The width of the raw material carrier 5 on both sides is larger than the size of the middle hollow of the conveyor belt. The two sides are stuck on the conveyor belts on both sides for transportation, and the lifting workbench located at the work station 13 is lifted and lowered by a hydraulic or pneumatic power cylinder. The staff can adjust its lifting height according to its height adjustment, so that the position of the raw material carrier 5 it holds up is suitable for the workers to operate. Secondly, the high-frequency oscillation device is also provided on the support plate of the lifting workbench that is raised and abuts against the bottom of the raw material carrier 5 and is engaged with the bottom groove thereof. The purpose of setting the high-frequency oscillation device is to vibrate the raw materials to disperse them and alleviate some raw material stacking problems.

[0046] As a further configuration of the above scheme, a loading platform 19 is provided on the annular raw material conveying line 1, each loading platform 19 corresponds to a raw material carrier 5, and the raw material carriers 5 circulating on the annular raw material conveying line 1 and the workstation conveyor belt 4 are greater than the total number of loading platforms 19 of the annular raw material conveying line 1.

[0047] As a further arrangement of the above scheme, the side walls of the annular raw material conveyor line 1 facing the side push device 8 are provided with side push steps, the four corners of the raw material carrier 5 are provided with guide wheels 51, and the corresponding positions of the annular raw material conveyor line 1, the work station conveyor belt 4, the loading conveyor line 9 and the finished product conveyor line 3 are provided with guide bevels 52 matching the guide wheels 51. The guide wheels 51 and the guide bevels 52 in this embodiment are arranged so that once a small deviation occurs during the pushing of the side push device 8, it can be automatically returned to the center through the guide bevel 52, and the guide wheel 51 reduces the sliding friction and makes it perform rolling friction. The purpose of setting the side push steps is to guide the raw material carrier 5 from the annular raw material conveyor line 1 into the work station conveyor belt 4 for guidance.

[0048] Embodiment: The present invention also provides a method for operating a multi-stage production line for factory processing using the above device, comprising the following steps:

[0049] Based on the fact that the assembly line of the present invention belongs to processing, therefore, before the assembly line works, it is necessary to connect the feeding conveyor line 9, such as Figure 2 As shown, a group of feeding conveyor lines 9 are connected to one side of the circular raw material conveyor line 1. In this embodiment, the feeding conveyor line 9 needs to be equipped with an infrared sensor 62 on the circular raw material conveyor line 1 to ensure that the raw material carrier 5 with raw materials will be fed in only when the carrier platform 19 on the circular raw material conveyor line 1 is missing. The raw material conveying of the raw material carrier 5 on the feeding conveyor line 9 can be fed manually or mechanically according to the actual situation.

[0050] S1: With the assistance of external employees, the circular raw material conveyor line 1 is uniformly loaded, and the process technology of the raw materials is entered into the control system. For example, in the control system of the present invention described above, targeted processing strategies are pre-set for different agricultural products or material processing, and the process technology required for processing is entered into the database of the control system. When the assembly line is running, the person in charge selects the type of raw materials currently loaded on the circular raw material conveyor line 1, thereby debugging the process technology in the control system;

[0051] S101: In the present invention, the main functions of the control system include debugging the process and integrating the control information of the entire assembly line, among which the control system mainly plays a role in triggering feedback of the control information, that is, the barcode printed at the corresponding position of each raw material carrier 5. Further, when the raw material carrier 5 is circulated on the assembly line, the barcode of the raw material carrier 5 is read based on the sensing unit 6, and the preset current state of the material is entered into the database. It is worth noting here that the raw material carrier 5 is directly circulated on the annular raw material conveyor line 1. After the barcode is read, the raw material information in the raw material carrier 5 in the database remains unchanged. When the raw material carrier 5 enters the workstation conveyor belt 4 each time, the information data is automatically updated in the process of entering the finishing step 14 from the working position 13 through the triggering of the control switch 7. When the barcode information is read again, it is updated and changed. At this time, the sensing unit 6 can judge according to the changed information that the raw material carrier 5 should comply with the process of a certain workstation conveyor belt 4 or the output of the finished product conveyor line 3;

[0052] S2: It is worth noting that in the embodiment of the present invention, each workstation conveyor belt 4 complies with a specific process (under the premise that the raw materials need to be processed through multiple processes). In the design of the present invention, it is preferred that each workstation conveyor belt 4 is arranged in a process along the flow direction of the annular raw material conveyor line 1. However, the design different from the prior art is that the process station position of the present invention can be arranged in disorder. Under the conditions permitted (generally, the process will not cause complicated processing, that is, there will not be too many people in a certain process and no one in some processes), workers can arbitrarily choose to change the current processing process according to their preferences or expertise without changing workstations. At the beginning of work, after the worker enters the corresponding process station conveyor belt 4, he selects the corresponding operation process and the workstation conveyor belt 4 number in the control system (the purpose of the number is to facilitate the corresponding process), and the linkage feeding sensor 61 of the workstation conveyor belt 4 reads the code of the raw material carrier 5 on the annular raw material conveyor line 1, and feeds the material through the side push device 8;

[0053] S201: As mentioned above, after the operator enters the workstation conveyor belt 4 and officially starts working, he selects the number of the processing procedure by operating the control system on the current workstation conveyor belt 4. The control system sends the worker's working procedure to the main server, and the control system integrates the worker's process technology and calculates to ensure uniform flow distribution. The purpose of the integration is as mentioned above, which is to avoid uneven process distribution, thereby causing the problem of accumulation of raw materials in the process of processing some processes;

[0054] S202: At this time, the annular raw material conveyor line 1 is already in circulation. The circulation here means that the raw materials mentioned in S1 have entered the annular raw material conveyor line 1 to ensure the supply of raw materials. The sensing unit 6 of the current station scans the raw material carrier 5 passing by. The scanning target is a barcode. The present invention sets a loading sensor 61, which can scan the barcode and feed back to the database of the control system to quickly obtain the information of the raw material in the current raw material carrier 5, so as to determine whether to start the side push device 8 to send it into the station conveyor belt 4, and constantly compare it with the processing procedure of the current station conveyor belt 4. It is worth noting that there are two determining factors for determining whether to start the side push device 8: ① Whether the processing requirements of the next process of the raw material correspond to the process number on the current station conveyor belt 4; ② The waiting seat 12 on the current station conveyor belt 4 is vacant, allowing the raw material carrier 5 to be pushed in;

[0055] S203: When the material carrier 5 corresponds to the processing step, the control system controls the side push device 8 to start, the power cylinder 81 drives the push arm 82 to extend, pushes the material carrier 5 into the waiting seat 12 of the workstation conveyor belt 4, and then the push arm 82 is reset;

[0056] S3: After the workstation conveyor belt 4 is loaded, the stepper motor is not shown in the figure of this embodiment. In the scheme of the present invention, the workstation conveyor belt 4 can circulate by itself. The only purpose of the circulation is to transfer the raw material carrier 5 on the waiting seat 12 to the working position 13, and to transfer the raw material carrier 5 on the working position 13 to the finished seat 14. Therefore, any conveyor belt driving device of the prior art that meets the above requirements can be used. The driving workstation conveyor belt 4 of this embodiment is activated to transfer the raw material carrier 5 between the waiting seat 12, the working position 13 and the finished seat 14. It is worth It is noted that after the raw material carrier 5 is pushed into the finishing seat 14, the raw material carrier 5 waits here to be sent back to the annular raw material conveying line 1 by the side push device 8. It is worth noting here that the raw material carrier 5 is pushed back to the annular raw material conveying line 1 by the side push device 8 arranged on the station conveyor belt 4 on the premise that a carrier 19 capable of accommodating the raw material carrier 5 appears on the annular raw material conveying line 1. When the extreme occurs, that is, before the raw material carrier 5 is pushed into the annular raw material conveying line 1, and the raw material on the working station 13 is processed, the worker can manually remove it from the station conveyor belt 4;

[0057] S301: The raw material carrier 5 is pushed into the workstation conveyor belt 4 by the side push device 8 on the circular raw material conveyor line 1 and enters the waiting seat 12 first. When there is no raw material on the workstation 13, the stepper motor of the driving unit of the workstation conveyor belt 4 is started to send the raw material carrier 5 on the waiting seat 12 to the workstation 13;

[0058] S302: When there is no raw material carrier 5 on the waiting seat 12, the sensing unit 6 of the control system will feedback a signal, and when the loading sensor 61 detects that the raw material carrier 5 passing by meets the loading requirement, the side pusher 8 will be immediately started to fill the position;

[0059] S303: When the worker finishes processing the raw material in the raw material carrier 5 on the working position 13 and presses the control switch 7, the stepper motor starts again to transport the raw material carrier 5 on the waiting seat 12 to the working position 13, and at the same time, the raw material carrier 5 on the working position 13 moves backward to the finishing seat 14;

[0060] It is worth noting that the purpose of the above-mentioned setting is to ensure the continuity of the processing process on the workstation 13. Compared with the prior art, the workpiece needs to be taken from the assembly line after completion. Once multiple people take materials at the same time, there will be a problem of raw material supply gap. The present invention proposes a method of automatically reserving processing raw materials to ensure that the supply on the workstation 13 will not have a shortage of materials during the process flow and processing. After the worker completes the processing, press the control switch 7, and the control system simultaneously transfers the processed raw material carrier 5 on the workstation 13 to the completion seat 14 to wait for entering the annular raw material conveying line 1, updates the database status information scanned by the barcode, and transfers the materials on the waiting seat 12 to the workstation 13 for the worker to continue processing.

[0061] S304: When the infrared sensor 62 of the circular material conveying line 1 detects an empty position, the side pusher 8 arranged on the side of the finishing seat 14 is started to push the material carrier 5 into the circular material conveying line 1 to complete the processing. The completed processing at this time includes the processing of a certain process among the multiple processes of the material. The purpose of pushing the material carrier 5 back to the circular material conveying line 1 is to make it re-enter the circulation for the corresponding process station to take, and secondly, if the last process is completed, that is, to return to the circular material conveying line 1 and move to the finished product conveying line 3 to unload it;

[0062] S4: After the raw material carrier 5 passes through the workstation conveyor belt 4, the processing information of the raw material carried on the barcode of the raw material carrier 5 in the database of the control system is updated according to the processing steps of the current workstation process when the control switch 7 is pressed. After it passes to the workstation conveyor belt 4 of the next corresponding process, the side push device 8 is triggered to push it into the loading according to whether the waiting seat 12 on the corresponding workstation conveyor belt 4 is vacant;

[0063] S5: The upper and lower raw material carriers 5 of the loading conveyor line 9 and the finished product conveyor line 3 are arranged to act in correspondence. When the sensing unit 6 arranged on the annular raw material conveyor line 1 reads that the raw material in the raw material carrier 5 is processed, when it reaches the finished product conveyor line 3, the corresponding side pushing device 8 is started to push it out of the annular raw material conveyor line 1 and into the finished product conveyor line 3. At the same time, the loading conveyor line 9 located behind it pushes the raw material carrier 5 containing new raw materials into the annular raw material conveyor line 1.

[0064] Furthermore, an off-position switch 75 is also provided on the work station 13. The off-position switch 75 is used to be triggered after the operator leaves the work station conveyor belt 4. The control system sends a command to start the stepper motor to return the unfinished processed raw material carrier 5 on the work station conveyor belt 4 to the annular raw material conveyor line 1, and closes the loading sensor 61 and the side thrust device 8 of the corresponding work station conveyor belt 4.

[0065] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
