[0003] However, some customers still need single medicine bottles. It costs a lot to design a production line specifically for single medicine bottles. Most of them will separate the linked medicine bottles manually, but this is time-consuming and labor-intensive. Manual separation requires more people, is slow, and has high labor intensity. If you are not careful during the separation process, it may cause quality defects such as product damage and leakage. Summary of the invention

[0004] An object of the present invention is to solve at least the above problems and to provide at least the advantages which will be described hereinafter.

[0005] The purpose of the present invention is to provide a device for separating connected medicine bottles, so as to solve the problem that the separation of existing connected medicine bottles is time-consuming and labor-intensive.

[0006] In order to achieve these purposes and other advantages according to the present invention, a device for separating connected medicine bottles is provided, including a conveyor belt and a limiting mechanism, wherein a plurality of push plates are arranged at intervals along the extension direction of the conveyor belt, and the extension direction of the push plates is perpendicular to the conveyor belt, and the limiting mechanism includes a fixed rod and a plurality of limiting bars, wherein the fixed rod is located directly above the conveyor belt, and the limiting bars are respectively fixed to the bottom of the fixed rod by a connecting rod, and the limiting bars are all located at the same horizontal position, and the limiting bars are arranged at equal intervals, and their extension direction is consistent with the conveyor belt, and passages are formed between adjacent limit bars, and cutters are arranged between adjacent passages, and the blade of the cutter faces the direction of incoming materials.

[0007] In a possible design, baffles are provided on both sides of the conveyor belt, and a channel is also formed between the baffles and the nearest limiting strip.

[0008] In a possible design, a guide opening is provided at the front end of the above-mentioned limiting mechanism, and the guide opening includes two side panels. The two side panels form a trumpet-shaped structure, and the two side panels are respectively fixed on two limiting strips that are farthest apart. The side panels are parallel to the conveyor belt below, and the side panels and the limiting strips are located at the same horizontal position, and the guide opening expands evenly from one end close to the limiting mechanism to the other end.

[0009] In a possible design, the above-mentioned cutters are all installed on a mounting frame located above the limiting bar, and the cutters pass through the limiting bar and extend to the bottom of the limiting bar.

[0010] In a possible design, the cutter is installed below the limiting strip between adjacent passages.

[0011] In a possible design, the upper end of the cutter is inclined toward the incoming material direction.

[0012] In a possible design, the distance between the limiting strip and the cutter and the conveyor belt is greater than the height of the push plate.

[0017] (1) The device is designed with a guide mechanism to limit the moving direction of the row of medicine bottles, and a cutter is designed in the guide mechanism. When the row of medicine bottles is pushed by the push plate through the guide mechanism, it is cut by the cutter, and each medicine bottle is automatically separated, replacing manual separation, saving manpower and time.

[0037] like Figure 1-15 The device for separating medicine bottles from connected plates comprises a conveyor belt 100 and a limiting mechanism 200. The conveyor belt 100 is provided with a plurality of push plates 101 at intervals along its extension direction. The extension direction of the push plates 101 is perpendicular to the conveyor belt 100. The limiting mechanism 200 comprises a fixed rod 201 and a plurality of limiting strips 202. The fixed rod 201 is located directly above the conveyor belt 100. The limiting strips 202 are respectively fixed to the bottom of the fixed rod 201 through a connecting rod 203. The limiting strips 202 are all located at the same horizontal position. The limiting strips 202 are arranged at equal intervals, and their extension direction is consistent with that of the conveyor belt 100. Passageways 204 are formed between adjacent limiting strips 202. A cutter 300 is provided between adjacent passageways 204, and the blade of the cutter 300 faces the direction of incoming materials.

[0038] Connected board medicine bottles are also called row medicine bottles, which are formed by blow molding a whole piece of plastic during processing. When the processing is completed, the medicine bottles are connected in a row with a fixed number of 3 to 6 medicine bottles. This embodiment uses 5 connected board medicine bottles as an example.

[0039] like Figure 1 In this embodiment, push plates 101 are arranged at intervals on the end surface of the conveyor belt 100, and the push plates 101 are fixed to the conveyor belt 100 by screws. In the limiting mechanism 200, a fixed rod 201 is arranged directly above the conveyor belt 100, and is arranged horizontally and perpendicular to the conveying direction of the conveyor belt 100. Support legs are arranged at both ends of the fixed rod 200, and the support legs are fixed on the support frame 102 of the conveyor belt 100. A limiting strip 202 is arranged under the fixed rod 200 so that the limiting strip 202 is suspended in the air.

[0040] like Figure 3When setting it specifically, you first need to know that the cross section of the medicine bottle 400 is elliptical (the lower and upper ends of the medicine bottle are flat, which is convenient for placing the medicine bottle). The medicine bottle 400 is placed horizontally, and there is a connecting block 401 between the medicine bottles 400. The thickness of the connecting block 401 is relatively thin, much smaller than the thickness of the medicine bottle 400. In general use, it can be bent back and forth manually and broken for use. Therefore, the height of the limit strip 202 (that is, the distance from the limit strip 200 to the conveyor belt 100) should be greater than the distance from the upper end face of the connecting block to the lower end face of the medicine bottle, but the height of the limit strip also needs to be less than the thickness of the medicine bottle. Of course, the thickness of the limit strip 202 also needs to be designed so that when the medicine bottle 400 is located in the passage 204, its two sides are respectively attached to the two limit strips 202, and at this time the connecting block 401 is located directly below the limit strip 202.

[0041] The design of the cutter 300 is such that the tip of the cutter 300 is located at the lower end, and the lowest point of the cutter 300 should exceed the connecting block 401 so that the connecting block 401 can be completely cut off.

[0042] The device provides two ways to install the cutter 300:

[0043] The first way of installing the cutter 300 is as follows: Figure 2 , the cutter 300 is mounted on a mounting frame 301 located above the limit strip 202, the cutter passes through the limit strip 202 and extends to the bottom of the limit strip 202. Specifically, a mounting frame 301 is designed directly above the limit strip, the mounting frame 301 is an L-shaped structure, the vertical rod is connected to the support frame 102, the horizontal rod is located above the limit strip 202, and a mounting plate 302 is designed, the handles 303 of the cutter 300 are arranged on the mounting plate 302, so that the cutter 300 is located in the same vertical position, and the cutting can be started at the same time, and the cutting is completed at the same time, avoiding the jumping of the medicine bottle 400, and the influence of the cutting completed first on the cutting completed later, because the limit strip 202 is preferably completely fitted with the medicine bottle 400, but in practice, there must be a margin, the height of the limit strip 202 is slightly high, and the medicine bottle 400 is somewhat loose inside.

[0044] Since the installation point of the cutter 300 is located above the limit strip 202, the blade of the cutter 300, or the tip of the cutter 300, should be located below the limit strip 202 to cut the connecting block 401 that is located directly below the limit strip 202. Therefore, a slot 205 is designed on the limit strip 202, and the tip of the cutter 300 passes through the slot 205 and extends to the bottom of the limit strip 202.

[0045] The second method of installing the cutter 300 is as follows: Figures 5 to 8The cutter 300 is installed below the limit strip 202 between adjacent passages 204, that is, the cutter 300 is set directly below the limit strip 202, and a mounting hole 206 can be designed on the limit strip 202, and a screw 304 is designed on the upper end of the cutter 300. The screw 304 passes through the mounting hole 206 and then is fixed by a nut.

[0046] The screw rod 304 is cylindrical, but at least one flat side 305 is designed on the peripheral wall, and the mounting hole 206 is also arranged in a matching manner, so that the screw rod 304 cannot rotate in the mounting hole 206, thereby ensuring the fixed installation of the cutter 300. In addition, the designed flat side 305 will not affect the fixed connection between the nut and the screw rod 304.

[0047] However, no matter how the cutter 300 is installed, its upper end is inclined toward the direction of the incoming material. This design is convenient for cutting the connecting block 401, and the oblique cutting can increase the cutting surface.

[0048] In the first mode, the cutter 300 is a long cutter and is not easily damaged. In the second mode, the cutter 300 is a short cutter and is easily broken, but is easy to install.

[0049] As for the design of the height of the push plate 101, there are two situations:

[0050] The first case, such as Fig. 9 , the distance between the limit bar 202 and the cutter 300 and the conveyor belt 100 is greater than the height of the push plate 101. In this way, when the push plate 101 passes under the limit bar 202 and the cutter 300, they will not touch each other. Therefore, the height of the push plate 101 must be lower than the lower end surface of the connecting block 401. After all, the cutter 300 needs to completely cut off the connecting block 401, and its lowest point must be lower than the lower end surface of the connecting block 401.

[0051] The second case, such as Fig.10 The push plate 101 is provided with a slot 103 that cooperates with the limit strip 202 and the cutter 300. The slot 103 is used to pass the limit strip 202 and the cutter 300. If the push plate 101 is designed with the slot 103, the height of the push plate 101 may not be excessively restricted.

[0052] When the device is working, the staff will place the connected medicine bottles horizontally on the conveyor belt 100. When the connected medicine bottles enter the limiting mechanism 200, it can ensure that one medicine bottle faces one passage 204. This requires the following design scheme:

[0053] The first design, such as Figures 1 to 4, baffles 104 are arranged on both sides of the conveyor belt 100, and a channel 105 is also formed between the baffles 104 and the nearest limit strips 202. As mentioned above, it is used to cut 5-piece medicine bottles, so 4 limit strips 202 are designed, plus the baffles 104 on both sides to form 3 passages 204 and 2 channels 105. As shown in the figure, the width of the passage 204 is consistent with that of the channel 105; as shown in the figure, the width of the channel 105 is slightly larger than the width of the passage 204.

[0054] The connected medicine bottles are placed on the conveyor belt 100, which means they are restricted and cannot rotate or deviate. The medicine bottles 400 enter the passage 204 or the channel 105, which is further restricted and cannot move up and down. When passing through the cutter 300, the push plate 101 restricts them from retreating, so that the connected medicine bottles are cut into separate medicine bottles 400.

[0055] The second design, such as Figures 11 to 14 A guide opening 500 is provided at the front end of the limiting mechanism 200, and the guide opening 500 includes two side panels 501. The two side panels 501 form a trumpet-shaped structure. The two side panels 501 are respectively fixed on the two limiting strips 202 that are farthest apart. The side panels 501 are parallel to the conveyor belt 100 below, and the side panels 501 and the limiting strips 202 are located at the same horizontal position. The guide opening 500 expands evenly from one end close to the limiting mechanism 200 to the other end.

[0056] This is a commonly used shaping structure in the processing line. Through the trumpet-shaped guide port 500, the connected plate medicine bottles are slowly adjusted, and the medicine bottles 400 will be aligned with the passage 204 one by one. In this design, the number of the limiting strips 202 is 6, forming 5 passages 204.

[0057] like Figure 1 , Figure 5, the above-mentioned limiting mechanism 200 extends to the rear end of the conveyor belt 100. That is, the limiting strip 202 extends to the end of the conveyor belt 100, ensuring that the medicine bottle 400 maintains a compact and parallel formation when leaving the conveyor belt 100, which is convenient for subsequent operations. In this embodiment, the limiting mechanism 200 is designed as two sections, including a front-end limiting mechanism 207 and a rear-end limiting mechanism 208. Because the cutter 300 is designed in the middle of the limiting strip 202, it is necessary to design a groove on the limiting strip, either for the cutter 300 to pass through, or for the cutter 300 to be installed. This will make the limiting strip 202 easy to break at this point. Therefore, in this embodiment, two sections are designed. In the front-end limiting mechanism 207, the cutter 300 is designed at the end of the limiting strip 202, so that it is not easy to break from the middle when carried. And the cutter 300 is not easy to be located at the end of the conveyor belt 100. In the process of being cut, the medicine bottle 400 must be kept moving in a straight line to ensure the cutting effect. Therefore, it is most reasonable to design it into two sections. The front limit strip 202 keeps the medicine bottle 400 stable, because the medicine bottle 400 is still on the conveyor belt 100 when being cut, ensuring that the medicine bottle 400 is cut smoothly. Then the medicine bottle enters the rear end limit mechanism 208 to ensure that the medicine bottle 400 leaves the conveyor belt 100 in formation.

[0058] like Figures 11 to 15 A self-inspection mechanism 600 is arranged at the rear end of the above-mentioned limiting mechanism 200, and the self-inspection mechanism 600 includes a plurality of detection strips 601, and the detection strips 601 are arranged at equal intervals. The extension direction of the detection strips 601 is consistent with the conveying direction of the conveyor belt 100, and a detection path 602 is formed between adjacent detection strips 601. The detection path 602 is consistent with the width of the passage 204, and the width of the detection strip 601 is greater than that of the limiting strip 201. A pressure sensor 700 is arranged on the end face of the push plate 101 facing the material removal direction, and the signal output end of the pressure sensor 700 is connected to the conveying motor 106 of the conveyor belt 100.

[0059] The self-inspection mechanism 600 is suitable for the second design scheme mentioned above. The self-inspection mechanism 600 is a larger limit mechanism 200, but the width of the detection strip 601 is larger. The height of the detection strip 601 is consistent with the height of the limit strip 202, and the width is slightly larger. The distance between the end faces of adjacent detection strips 601 is consistent with the distance between the end faces of adjacent limit strips 202. Therefore, two adjacent medicine bottles 400 must be separated to enter the detection channel 605 respectively.

[0060] If the adjacent medicine bottle 400 is not cut (maybe the cutter 300 is damaged), the medicine bottle 400 will be stuck between the self-checking mechanism 600 and the limit mechanism 200, so the push plate 101 will feel a large pressure, and the pressure sensor 700 will send a signal to the conveying motor 106, and the conveying motor 106 will stop working, and the conveyor belt 100 will no longer operate. The staff can check, take out the unseparated medicines, and run the device again.

[0061] Generally, a processor 107 is set up for central management. The signal of the pressure sensor 700 is output to the processor 107, and the processor 107 sends a control signal to the transmission motor 106. In addition, an audible and visual alarm 108 is set up. The processor also sends a signal to the audible and visual alarm 108, and the audible and visual alarm 108 emits an alarm sound to let the staff know. The pressure sensor 700 will continuously send pressure data to the processor 107, and a threshold value is set in the processor 107. When the pressure value is greater than a certain value, the transmission motor 106 will be controlled to stop and an alarm will be sounded.

[0062] In the self-inspection mechanism 600, the front end of the detection strip 601 is designed as a tip 604, which is connected and fixed to the detection frame 602 above through a connecting plate 603. The tail end of the self-inspection mechanism 600 is located at the tail end of the conveyor belt 101, which plays a shaping role to ensure that the medicine bottles 400 are always in a formation state before leaving the conveyor belt 101.

[0063] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
