Description

Technical Field

[0001] The invention relates to the technical field of drug production, and in particular to an automatic quantitative charging device for chemical drug powder. Background Art

[0002] In pharmaceutical production, large bags of finished chemical drug powders need to be packaged using quantitative loading equipment. Small amounts of powder are more convenient for subsequent storage and transportation, and are also convenient for doctors, nurses or patients to use directly. This not only improves the accessibility of drugs, but also reduces the waste that may be caused by large packaging. Quantitative loading can also ensure the consistency and repeatability of drug production, and meet the requirements of pharmaceutical production quality management standards.

[0003] Based on the above situation, in the prior art, the patent with publication number CN118701390A discloses a quantitative powder filling device, including a storage cylinder and a filling mechanism for quantitatively filling powder, a shielding plate that can block the discharge port can be slidably fixed at the discharge port of the storage cylinder, a cylindrical cavity is arranged in the storage cylinder, and the filling mechanism is arranged in the cylindrical cavity, the filling mechanism includes a fixed block in the shape of an annular plate, a quantitative plate and a rotating block, the outer ring of the annular plate of the fixed block is fixed against the inner wall of the cylindrical cavity of the storage cylinder, the upper plate surface of the fixed block is a concave surface, the quantitative plate is fixed and blocks part of the inner circle of the fixed block, the rotating block can be rotatably fixed below the quantitative plate, a plurality of quantitative grooves are provided on the upper surface of the rotating block, the notches of the quantitative grooves can be completely covered by the quantitative plate, the discharge port is arranged directly below the quantitative plate, and during the rotation of the quantitative groove, the through hole at the bottom can be directly opposite to the discharge port, the above-mentioned quantitative powder filling device solves the problem of inconvenience in using the powder in piles, and the present invention can facilitate users to fill the powder.

[0004] The above-mentioned powder quantitative packaging device has achieved the quantitative packaging function of powder to a certain extent, but it still has certain shortcomings in the accuracy of packaging drugs. Accurate quantitative packaging cannot be achieved between each portion of powder. Specifically, although the device quantifies the powder through the quantitative groove on the upper surface of the rotating block, it lacks an accurate weighing mechanism and packaging control mechanism to ensure that the amount of powder in each quantitative groove is completely consistent. Since the packaging only relies on the volume of the quantitative groove, and the volume of the quantitative groove may be affected by factors such as wear and tear, as well as the humidity of the powder, the density of the filling and other factors, there are relatively obvious errors between each portion of powder.

DETAILED DESCRIPTION

[0025] The implementation mode of the present invention is described below in conjunction with relevant embodiments. The implementation mode of the present invention is not limited to the following embodiments, and the present invention relates to relevant necessary components in the technical field, which should be regarded as the known technology in the technical field and can be known and mastered by the technical personnel in the technical field.

[0026] like Figures 1 to 8As shown, an automatic quantitative charging device for chemical powder includes a frame 1, a storage component 2 and a quantitative component 4, the storage component 2 is provided with a bucket-shaped material bin 21, the lower end of the bucket-shaped material bin 21 is provided with a discharge cylinder 22, the inside of the bucket-shaped material bin 21 is provided with a discharge rod 23, the discharge end of the discharge cylinder 22 is provided with a blocking component 3 fixedly connected to the frame 1, the blocking component 3 is provided with a blocking component 31, a mounting structure 32, and a collecting box 33, the collecting box 33 is installed at the rear end of the blocking component 31 through the mounting structure 32, A quantitative component 4 fixedly connected to the frame 1 is provided below the material blocking component 3, and the quantitative component 4 includes a material holding component 41 and an opening and closing component 42 arranged outside the material holding component 41, the opening and closing component 42 is symmetrically provided with an opening and closing plate 420 at the discharge end of the material holding component 41, the opening and closing component 42 is provided with a transmission component 43 fixedly connected to the opening and closing plate 420, and a discharge hopper 5 connected to the frame 1 is provided below the discharge end of the material holding component 41, and the frame 1 is installed with a control panel 6 for controlling the operation of the equipment.

[0027] The storage component 2 of the present invention is used for storing and supplying medicinal powder. The bucket-shaped silo 21 of the storage component 2 has a large capacity and can accommodate sufficient medicinal powder for continuous packaging. The discharge cylinder 22 is located at the lower end of the bucket-shaped silo 21. The discharge rod 23 is driven by the driving motor 25 to rotate in the discharge cylinder 22. The discharge rod 23 controls the movement speed of the medicinal powder in the discharge channel 27 through the external thread 231, thereby realizing precise adjustment of the medicinal powder discharge speed and ensuring the stability and continuity of the medicinal powder during the packaging process.

[0028] The material blocking assembly 3 of the present invention is used to control the flow of medicine powder and prevent the medicine powder from continuing to fall when it is not needed. The material blocking assembly 3 is located at the discharge end of the discharge barrel 22. The material blocking component 31 of the material blocking component 3 drives the L-shaped material blocking plate 312 to slide in the sliding groove 315 of the bottom plate 314 through the first electric cylinder 313, thereby realizing the blocking and opening of the discharge end of the discharge barrel 22. When it is necessary to stop the medicine powder from falling, the L-shaped material blocking plate 312 slides between the discharge channel 316 and the discharge end of the discharge barrel 22 to cut off the medicine powder. At the same time, the collecting groove 317 of the L-shaped material blocking plate 312 can also scrape off the medicine powder remaining at the discharge end of the discharge barrel 22 to avoid waste of medicine powder. The mounting structure 32 is responsible for mounting the collecting box 33 at the tail end of the material blocking component 31 to facilitate the collection of the medicine powder scraped off by the L-shaped material blocking plate 312.

[0029] The quantitative component 4 of the present invention is used for accurately measuring and packaging medicinal powder. The material containing component 41 of the quantitative component 4 has a material containing barrel 411 which passes through from top to bottom and is used for receiving the medicinal powder falling from the discharge barrel 22. The opening and closing component 42 controls the opening and closing of the opening and closing plate 420 through the transmission component 43, thereby realizing the falling of the medicinal powder in the material containing barrel 411 into the discharge hopper 5. When the medicinal powder in the material containing barrel 411 reaches the specified weight, the annular weighing sensor 414 will send a signal to stop the discharge rod 23 in the discharge barrel 22 from rotating. At the same time, the material blocking component 31 blocks the discharge end of the discharge barrel 22. Then, the opening and closing component 42 and the transmission component 43 operate in conjunction with each other, so that the opening and closing plate 420 is symmetrically tilted downward to open and pour the medicinal powder in the material containing barrel 411 into the discharge hopper 5.

[0030] The discharge hopper 5 of the present invention is located below the quantitative component 4, and is used to receive and output the quantitative medicine powder, and allow the medicine powder to fall smoothly into the container below. The outside of the discharge hopper 5 is also provided with a fixedly connected fixing ring 52 and a second fixing rod 53, which is connected to the frame 1 through the second fixing rod 53 to ensure the stability and reliability of the discharge hopper 5. At the same time, a vibration motor 51 is symmetrically installed on the outer wall surface of the bottom of the discharge hopper 5, which helps the medicine powder to fall better through vibration, thereby avoiding accumulation or blockage of the medicine powder in the discharge hopper 5.

[0031] The control panel 6 of the present invention is used to control and monitor the operating status of each component. The control panel 6 integrates various control buttons, display screens, controllers and other components, which facilitates the operator to accurately control and monitor the device in real time. Through the control panel 6, the operator can conveniently adjust the discharge speed, quantitative weight and other parameters of the powder, and monitor the operating status of the device in real time to ensure that the device can operate stably and efficiently. Specifically, in the structure of the present invention, the control panel 6 can control the start, stop and speed adjustment of the drive motor 25 by being electrically connected. The drive motor 25 drives the discharge rod 23 to rotate in the discharge barrel 22, and controls the movement speed of the powder in the discharge channel 27 through the external thread 231, thereby realizing the control of the powder discharge speed.

[0032] The control panel 6 is electrically connected to the first electric cylinder 313, and can control the extension and retraction of its telescopic rod. The first electric cylinder 313 drives the L-shaped material blocking plate 312 to slide in the sliding groove 315 of the bottom plate 314, thereby sealing and opening the discharge end of the discharge barrel 22, and scraping off the powder remaining at the discharge end of the discharge barrel 22.

[0033] The control panel 6 can control the up and down movement of the telescopic rod of the second electric cylinder 425 by electrically connecting the second electric cylinder 425 and the electromagnet 426. The second electric cylinder 425 drives the electromagnet 426 to attract or separate from the permanent magnet 424 on the top of the sliding sleeve 421, thereby controlling the rise and fall of the sliding sleeve 421, and then controlling the opening and closing of the opening and closing plate 420 through the transmission component 43.

[0034] The control panel 6 is electrically connected to the annular weighing sensor 414, and the annular weighing sensor 414 can receive the weighing signal sent by it in real time. The annular weighing sensor 414 weighs the powder falling into the material holding barrel 411. When the powder reaches the specified weight, a signal is sent to the control panel 6, and the control panel 6 then controls the storage component 2, the blocking component 3 and other components to perform corresponding actions.

[0035] The control panel 6 can control the start and stop of the vibration motor 51 by being electrically connected to the vibration motor 51. The vibration motor 51 is installed on the bottom outer wall surface of the discharge hopper 5 to help the powder fall better through vibration to avoid the powder from accumulating or clogging in the discharge hopper 5.

[0036] As one of the preferred embodiments of the present invention, Figure 1 , Figure 3 and Figure 4 As shown, the top of the bucket-shaped silo 21 is connected to a radially arranged mounting frame 26, a driving motor 25 is installed at the center position of the mounting frame 26, the upper end of the discharging rod 23 is connected to the power output shaft of the driving motor 25, the lower end of the discharging rod 23 is placed in the discharging barrel 22 and is arranged flush with the discharging end of the discharging barrel 22, the discharging rod 23 is connected to a stirring frame 24 inside the bucket-shaped silo 21, a discharging channel 27 is provided between the discharging rod 23 and the discharging barrel 22, and the discharging rod 23 is provided with an external thread 231 on the outer surface corresponding to the discharging barrel 22 section.

[0037] The medicine powder is stored in the bucket-shaped silo 21. When the medicine powder needs to be packaged, the driving motor 25 is started to drive the discharging rod 23 to rotate, and the discharging rod 23 drives the stirring frame 24 to rotate together, thereby stirring the medicine powder in the bucket-shaped silo 21 to ensure that the medicine powder is evenly distributed and avoid agglomeration or uneven accumulation. While the discharging rod 23 is rotating, the external thread 231 on its outer surface will produce friction with the medicine powder, thereby controlling the discharge speed of the medicine powder through the discharge channel 27. Specifically, when the discharging rod 23 rotates, the external thread 231 will push the medicine powder to move downward along the discharge channel 27. Due to the existence of the external thread 231, the discharge speed of the medicine powder will be subject to a certain limit, thereby achieving precise control of the discharge speed. After stirring and speed control, the medicine powder will smoothly fall from the discharge end of the discharging barrel 22 and enter the subsequent quantitative component 4 for packaging.

[0038] As one of the preferred embodiments of the present invention, Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the material blocking component 31 includes a fixed plate 311 arranged above the discharge end of the discharge barrel 22 and connected to the outer wall of the discharge barrel 22, a bottom plate 314 arranged at the discharge end of the discharge barrel 22, an L-shaped material blocking plate 312 arranged in the bottom plate 314 and capable of sliding freely on the bottom plate 314, and a first electric cylinder 313 symmetrically arranged on the upper surface of the fixed plate 311.

[0039] In the structure of the present invention, the upper surface of the horizontal section of the L-shaped material blocking plate 312 is tightly attached to the discharge end of the discharge barrel 22, and the bottom plate 314 is provided with a sliding groove 315 that can slide with the L-shaped material blocking plate 312, the telescopic rod of the first electric cylinder 313 is connected to the top of the vertical section of the L-shaped material blocking plate 312, and the bottom plate 314 is provided with a discharge channel 316 corresponding to the discharge end position of the discharge barrel 22 in the sliding groove 315.

[0040] During the powder packaging process, when the powder in the storage component 2 falls through the discharge barrel 22, the L-shaped material blocking plate 312 can prevent the powder from continuing to fall, thereby ensuring that the amount of powder packaged each time is accurate. During the sliding process of the L-shaped material blocking plate 312, a collecting groove 317 is provided at the edge of the horizontal section close to the collecting box 33. When the L-shaped material blocking plate 312 slides toward the collecting box 33, the powder remaining at the discharge end of the discharge barrel 22 can be scraped into the collecting groove 317, and as the L-shaped material blocking plate 312 slides further, it falls into the collecting box 33, which helps to reduce the waste and pollution of the powder.

[0041] When the powder in the material holding part 41 in the metering component 4 reaches the specified weight, the control panel 6 will issue an instruction to make the first electric cylinder 313 drive the L-shaped material blocking plate 312 to slide on the bottom plate 314, thereby blocking the discharge end of the discharge barrel 22. At this time, the metering component 4 can start the unloading operation to discharge the powder in the material holding part 41 into the discharge hopper 5. When the powder needs to be packaged again, the first electric cylinder 313 will drive the L-shaped material blocking plate 312 to slide in the opposite direction, so that the discharge channel 316 and the discharge end of the discharge barrel 22 are reconnected, thereby allowing the powder to continue to fall.

[0042] As one of the preferred embodiments of the present invention, Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, the mounting structure 32 includes an L-shaped fixed groove 321 arranged on both sides of the rear end of the bottom plate 314, a fixed abutment plate 323 slidably arranged in the L-shaped fixed groove 321, and a fixed spring 324 arranged along the sliding direction of the fixed abutment plate 323 and connecting the fixed abutment plate 323 and the inner wall of the L-shaped fixed groove 321; the inner wall surface of the L-shaped fixed groove 321 is provided with an L-shaped sliding groove 322 that can slide in cooperation with the fixed abutment plate 323.

[0043] In the structure of the present invention, the left and right sides of the collection box 33 are provided with an outer protrusion 333 that can slide in the L-shaped fixed groove 321, and the fixed abutment plate 323 abuts against the collection box 33 at the rear surface of the outer protrusion 333 through a fixed spring 324. The top of the collection box 33 is provided with a movably opened and closed top cover 331, and the top of the top cover 331 is provided with a hinge 332 at the edge position close to the rear surface of the collection box 33. The upper surface of the top cover 331 is movably connected to the rear surface of the collection box 33 through the hinge 332, and the front surface of the collection box 33 is provided with a collection port 334 that is flush with and connected to the sliding groove 315.

[0044] The L-shaped fixing groove 321 is arranged on both sides of the tail end of the bottom plate 314, providing a sliding track for the outer protrusions 333 on both sides of the collection box 33. The fixed abutment plate 323 is slidably arranged in the L-shaped fixing groove 321 and is connected to the inner side wall of the L-shaped fixing groove 321 through the fixing spring 324. When the collection box 33 is placed in the L-shaped fixing groove 321, the fixed abutment plate 323 will move outward under the action of the fixing spring 324 until it abuts against the outer protrusions 333 on both sides of the collection box 33, thereby ensuring the stability and firmness of the collection box 33 during installation. The fixing spring 324 slides along the fixed abutment plate 323 The direction setting provides necessary elastic force for the fixed abutment 323. When the collection box 33 is placed in the L-shaped fixed groove 321 and slides forward, the fixed spring 324 will be compressed; and when the collection box 33 reaches the predetermined position, the fixed spring 324 will release the elastic force and push the fixed abutment 323 to move outward, thereby tightly against the outer protrusion 333 of the collection box 33. The L-shaped slide groove 322 is set on the inner wall surface of the L-shaped fixed groove 321, and slides with the fixed abutment 323 to ensure that the fixed abutment 323 can slide along the predetermined trajectory, and also prevent the fixed abutment 323 from deviating or falling off during the sliding process.

[0045] When installing the collecting box 33, it is only necessary to align the outer protrusions 333 on both sides of the collecting box 33 with the L-shaped fixing grooves 321 and push the collecting box 33 forward. As the collecting box 33 slides, the fixed abutment plate 323 will gradually move outward under the action of the fixing spring 324 until it is in close contact with the outer protrusions 333 of the collecting box 33. At this time, the collecting box 33 is stably installed on the base plate 314 and is ready to receive the residual powder from the L-shaped blocking plate 312.

[0046] During the powder packaging process, the L-shaped blocking plate 312 slides toward the collecting box 33 and scrapes the residual powder collected on its horizontal section into the collecting groove 317. During this process, the L-shaped blocking plate 312 blocks the discharge end of the discharge barrel 22 and the discharge channel 316 of the bottom plate 314, thereby sealing the discharge end of the discharge barrel 22. As the L-shaped blocking plate 312 slides further, the collecting groove 317 enters the collecting box 33 from the collecting port 334 of the collecting box 33. When the discharge end of the discharge barrel 22 and the discharge channel 316 of the bottom plate 314 need to be connected again, the first electric cylinder 313 drives the L-shaped blocking plate 312 to move in the opposite direction in the sliding groove 315. At this time, due to the effect of inertia, the powder in the collecting groove 317 falls into the collecting box 33. This process not only reduces the waste of powder, but also improves the accuracy and efficiency of powder packaging.

[0047] The collecting box 33 is conveniently mounted on the bottom plate 314 through the mounting structure 32, and is also convenient for disassembly and cleaning. When the powder in the collecting box 33 accumulates to a certain amount, the operator can easily take it out from the L-shaped fixing groove 321, and clean and replace it. The hinge 332 is used to connect the top cover 331 and the rear surface of the collecting box 33, and allows the top cover 331 to be on the top of the collecting box 33. The existence of the hinge 332 also makes the opening and closing operation of the top cover 331 more convenient. The operator only needs to gently push or pull the top cover 331 to open and close the top cover 331 by rotating the hinge 332, thereby facilitating the operator to pour out the powder collected in the collecting box 33.

[0048] As one of the preferred embodiments of the present invention, Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, the material holding component 41 is provided with a material holding barrel 411 which passes through from top to bottom, the material holding barrel 411 is connected to a receiving hopper 412 at the feeding end, the opening and closing plate 420 is symmetrically arranged on the surface of the discharging end of the material holding barrel 411, the material holding barrel 411 is provided with a connecting ring 416 at the feeding end, a mounting ring 413 which is movably sleeved on the outside of the material holding barrel 411 is provided below the connecting ring 416, an annular weighing sensor 414 is installed between the connecting ring 416 and the mounting ring 413, the left and right surfaces of the mounting ring 413 are connected to first fixing rods 415, and the mounting ring 413 is connected to the frame 1 via the first fixing rods 415.

[0049] When the powder in the discharge barrel 22 falls into the receiving hopper 412 through the discharge channel 316 of the material blocking component 31, the powder will slide downward through the receiving hopper 412 and finally enter the interior of the material barrel 411. As the powder is added, the annular weighing sensor 414 will monitor the weight of the powder in the material barrel 411 in real time, and feed back this information to the control panel 6. When the powder reaches the preset weight, the control panel 6 will issue an instruction to stop the discharge action of the discharge barrel 22. After the powder reaches the preset weight, the opening and closing component 42 will open the opening and closing plate 420 through the transmission component 43 under the instruction of the control panel 6, so that the powder in the material barrel 411 can fall smoothly into the discharge hopper 5 below, and then the powder in the discharge hopper 5 falls into the container below it accordingly.

[0050] After one sub-packaging is completed, the opening and closing component 42 will close the opening and closing plate 420 under the instruction of the control panel 6 to prepare for the next sub-packaging. At the same time, the annular weighing sensor 414 will also be reset and ready to monitor the weight of the medicine powder added next time.

[0051] As one of the preferred embodiments of the present invention, Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, the opening and closing component 42 is also provided with a sliding sleeve 421, a mounting plate 422, a reset spring 423 and a second electric cylinder 425. The sliding sleeve 421 is slidably sleeved on the outside of the material barrel 411. The mounting plate 422 is arranged below the sliding sleeve 421 and is fixedly connected to the outer wall of the material barrel 411. The two ends of the reset spring 423 are respectively fixedly connected to the lower surface of the sliding sleeve 421 and the upper surface of the mounting plate 422. The second electric cylinder 425 is symmetrically arranged on the left and right sides of the material barrel 411 and is connected to the bottom plate 314. The telescopic rod end of the second electric cylinder 425 is connected with an electromagnet 426. The sliding sleeve 421 is provided with a permanent magnet 424 corresponding to the position of the electromagnet 426 at its top edge.

[0052] In the structure of the present invention, the transmission component 43 includes a second connecting rod 432 correspondingly connected to the opening and closing plate 420, a hinge seat 434 symmetrically arranged on the outer wall surface of the lower end surface of the sliding sleeve 421, a first connecting rod 431 whose two ends are respectively hinged to the second connecting rod 432 and the hinge seat 434, a connecting rod 436 symmetrically connected to one side of the lower surface of the mounting plate 422, and a rotating cylinder 435 connected to the lower end of the connecting rod 436, the second connecting rod 432 is correspondingly arranged between the connecting rods 436, the surface of the second connecting rod 432 is connected to a rotating support rod 433 corresponding to the position of the rotating cylinder 435, and the rotating support rod 433 is movably sleeved inside the rotating cylinder 435.

[0053] At the beginning of the powder packaging process, the opening and closing component 42 is in its initial state. At this time, the sliding sleeve 421 is held in a fixed position outside the material barrel 411 by the return spring 423, and the second connecting rod 432 is held in a horizontal position under the support of the connecting rod 436 and the rotating cylinder 435, so that the opening and closing plate 420 is closely attached to the lower end of the material barrel 411 through the connection between the hinge seat 434 and the first connecting rod 431.

[0054] When it is necessary to release the powder in the material holding barrel 411, the second electric cylinder 425 starts to move and drives the permanent magnet 424 to descend. The electromagnet 426 generates magnetism under the action of electricity and is attracted to the permanent magnet 424 on the top of the sliding sleeve 421. As the electromagnet 426 and the permanent magnet 424 are tightly attracted, the second electric cylinder 425 drives the electromagnet 426 (and the sliding sleeve 421 attracted thereto) to rise together. The rising motion of the sliding sleeve 421 is transmitted to the first connecting rod 431 through the hinge seat 434. Since one end of the first connecting rod 431 is hinged to the bottom of the sliding sleeve 421, the second electric cylinder 425 drives the electromagnet 426 (and the sliding sleeve 421 attracted thereto) to rise together. The first end of the sliding sleeve 421 is connected to the seat 434, and the other end is connected to the second connecting rod 432. Therefore, the rise of the sliding sleeve 421 will cause the first connecting rod 431 to tilt and rise, and the tilting and rising of the first connecting rod 431 further drives the tilting of the second connecting rod 432. The surface of the second connecting rod 432 is connected with a rotating support rod 433. The tilting of the second connecting rod 432 will cause the rotating support rod 433 to rotate in the rotating cylinder 435. As the second connecting rod 432 tilts, the opening and closing plate 420 gradually separates from the lower end of the material barrel 411, forming an opening, allowing the powder in the material barrel 411 to fall into the discharge hopper 5.

[0055] When the powder in the material barrel 411 is completely released, the power is cut off to the electromagnet 426 of the second electric cylinder 425. At this time, the attraction of the electromagnet 426 to the permanent magnet 424 disappears, and the reset spring 423 pulls the sliding sleeve 421 down and resets. As the sliding sleeve 421 descends, the first connecting rod 431 and the second connecting rod 432 also move in the opposite direction and reset, and finally the opening and closing plate 420 is blocked at the lower end of the material barrel 411 again.

[0056] As one of the preferred embodiments of the present invention, Figure 2 and Figure 8 As shown, a fixed ring 52 is fixedly connected to the outside of the discharge hopper 5, and a second fixed rod 53 is symmetrically connected to the left and right sides of the fixed ring 52. The fixed ring 52 is connected to the frame 1 through the second fixed rod 53, and a vibration motor 51 is symmetrically installed on the outer wall surface of the bottom of the discharge hopper 5.

[0057] When the opening and closing component 42 opens the opening and closing plate 420 at the lower end of the material barrel 411, the powder in the material barrel 411 will fall into the discharge hopper 5, and then the vibration motor 51 will start and generate high-frequency vibrations. These vibrations will act on the bottom and side walls of the discharge hopper 5 to help the powder to be discharged more smoothly. As the vibration continues, the powder will gradually be discharged from the bottom of the discharge hopper 5 and fall into the container below it. When the powder in the discharge hopper 5 is completely discharged, the vibration motor 51 will stop working. At this time, the discharge hopper 5 is in an idle state, waiting for the next powder discharge task.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
