Description

TECHNICAL FIELD

[0001] The utility model relates to a bottle sorting equipment technical field, specifically, relates to a filling machine bottle automatic rejection device. BACKGROUND

[0002] The special filling and sealing integrated machine is one of the commonly used equipment in the pharmaceutical industry, which is used for filling, capping and sealing oral liquid medicine. The special filling and sealing integrated machine has the advantages of fast production speed, high efficiency, stable filling amount, etc., and can be connected with the front plastic bottle washing machine or glass bottle washing and drying equipment and the rear packaging line equipment through the conveying track to form an automatic production line. After the medicine bottles are cleaned by the bottle washing machine, they enter the filling track through the bottle conveying track, the bottle feeding auger and the bottle feeding wheel. The medicine liquid is filled into the medicine bottles by the peristaltic pump on the filling track. Then the bottles enter the capping station through the bottle discharging auger and the wheel. After capping and sealing, the bottles are conveyed to the packaging line through the conveying track to complete the product packaging. The whole automatic production line has high automation degree and stable and reliable product quality.

[0003] At present, most medicine bottles are plastic bottles, and the empty plastic bottles are relatively light in weight. When the medicine bottles pass through the production line, especially during the conveying process of the net belt on the conveying track after the bottles are cleaned, the conveying speed is fast, and the medicine bottles are prone to fall over. The fallen bottles cannot be smoothly conveyed to the filling station through the auger and the wheel for normal filling, but will be directly stuck in the bottle feeding auger in front of the filling station, causing production stoppage, and even the risk of auger misalignment or damage, greatly reducing the production efficiency. Therefore, to ensure smooth production, a person needs to be arranged to check whether the medicine bottles fall over when the bottles are on the conveying net belt before filling. This method greatly increases the labor cost.

[0004] In order to automatically reject the fallen medicine bottles, the utility model patent with the application number 202320549973.5 discloses a full-automatic material sorting machine for pesticide bottles. A corner belt is arranged on the conveying belt, and an opening is formed on the outer side of the corner belt. A push plate is installed on the corner belt. The length of the medicine bottle in the fallen state is greater than the diameter of the medicine bottle in the upright state, so that the fallen medicine bottle is automatically discharged from the opening through the guidance of the push plate during the conveying process on the conveying belt. Although this method can reject the fallen medicine bottles, the upright medicine bottles are prone to be directly discharged from the opening due to the inertial force when passing through the corner, causing the upright medicine bottles to be mistakenly rejected. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a filling machine bottle automatic rejection device, which can effectively and accurately reject the fallen medicine bottles, solve the problem of production stoppage caused by the fallen bottles of the special filling and sealing integrated machine, keep the filling line production smooth, improve the production efficiency, and reduce the labor cost.

[0006] The technical scheme that the utility model discloses is adopted as follows: a filling machine bottle automatic removing device, including a conveying belt, guide plates installed on both sides of the conveying belt, the inner side of the two guide plates is all guide surface, the guide surface has a bending surface, the conveying channel with the bending part is formed between the two guide surfaces, the distance between the lower surface of the guide plate located on the outer side of the bending part and the conveying surface of the conveying belt is greater than the diameter of the medicine bottle and less than the height of the medicine bottle, and the distance between the lower surface of the guide plate located on the inner side of the bending part and the conveying surface of the conveying belt is less than the diameter of the medicine bottle.

[0007] Further, the bending part is at least one, and the bending part comprises an inclined section and a straight section, the straight section is parallel to the feeding end of the conveying channel, and the inclined directions of the inclined sections in the adjacent two bending parts are opposite.

[0008] Further, the included angle between the inclined section and the straight section is 105-150 degrees.

[0009] Further, the bending point of the conveying channel is in arc transition.

[0010] Further, the edge of the conveying surface of the conveying belt corresponds to the central axis of the straight section.

[0011] Further, a collecting frame is arranged below the conveying channel.

[0012] Further, the two sides of the conveying belt also have a baffle bar connected with the two ends of the guide surface, and the distance between the baffle bar and the conveying surface of the conveying belt is less than the diameter of the medicine bottle.

[0013] Further, the conveying belt is a mesh belt conveyor.

[0014] The utility model discloses the beneficial effect is:

[0015] By installing the guide plate on the two sides of the conveying belt, and setting the guide surface on the inner side of the guide plate, the conveying channel with the bending part is formed between the two guide surfaces, and the distance between the lower end of the conveying channel and the conveying surface of the conveying belt is set, so that the medicine bottle in the upright state can be normally conveyed forward when passing through the conveying channel, and since the medicine bottle is cylindrical, the medicine bottle in the pouring state will roll out and fall through the gap between the conveying channel and the conveying surface of the conveying belt when passing through the bending part, so that the medicine bottle in the pouring state is accurately removed.

[0022] The utility model will be further explained in detail in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related content, and not limited to the utility model. In addition, it needs to be explained that, in order to facilitate the description, only the part related to the utility model is shown in the drawings.

[0023] It needs to be explained that, in the case of no conflict, the embodiments and the features in the embodiments in the utility model can be combined with each other. The utility model will be explained in detail in combination with the drawings and embodiments.

[0024] As shown in Figure 1 , Figure 2 The utility model provides a kind of automatic rejecting device of filling machine bottle pouring, including the conveying belt 1 for conveying medicine bottle, the two sides of conveying belt 1 are provided with guide plate 2, the width direction of guide plate 2 is consistent with the width direction of conveying belt 1, and guide plate 2 is installed, and the both ends of guide plate 2 are fixed and supported on the body of conveying belt 1 by support 6;At the same time, after installation, the both ends of guide plate 2 are at a certain distance from the both ends of conveying belt 1, so that guide plate 2 is located in the middle section of conveying belt 1, so that medicine bottle enters the input end of conveying belt 1 first in the process of conveying by conveying belt 1, and enters between two guide plates 2 by the conveying of conveying belt 1, finally, it is sent out from the output end of conveying belt 1 by the conveying of conveying belt 1.

[0025] It should be noted that the conveying belt 1 in the utility model refers to a whole conveying belt 1, not one conveying section, that is, the conveying belt 1 can be formed by sequentially connecting a plurality of conveying sections, or be a conveying belt 1 formed by only one conveying section, but the conveying belt 1 is formed by sequentially connecting a plurality of conveying sections or only one conveying section, and the guide plates 2 are located at the middle section of the conveying belt 1; therefore, when the conveying belt 1 is formed by sequentially connecting a plurality of conveying sections, the guide section can be located at the feeding end or the discharging end of one conveying section, and since the conveying section is also connected with other conveying sections, the medicine bottles can normally enter or be discharged between the two guide plates 2.

[0026] When the medicine bottles pass between the two guide plates 2, the guide surfaces 3 of the guide plates 2 can adjust the medicine bottles in the width direction of the conveying belt 1, specifically, when the medicine bottles pass through the conveying belt 1, the inner side surface of the guide plate 2 is taken as the guide surface 3 to guide the position of the medicine bottles on the conveying belt 1, and through the cooperation of the two guide plates 2, a conveying channel 4 is formed between the guide surfaces 3 of the two guide plates 2. When the guide plate 2 is designed, a bending surface is arranged on the guide surface 3 of the guide plate 2, so that the conveying channel 4 formed by the cooperation of the two guide plates 2 has a bending part 5.

[0027] In order to ensure that the medicine bottles in the pouring state can be removed during the guiding process of the medicine bottles through the two guide plates 2, when the guide plate 2 is installed, the gap between the lower surface of the guide plate 2 located outside the bending part 5 and the conveying surface of the conveying belt 1 is greater than the diameter of the medicine bottle and less than the height of the medicine bottle, and the gap between the lower surface of the guide plate 2 located inside the bending part 5 and the conveying surface of the conveying belt 1 is less than the diameter of the medicine bottle. It should be noted that the outside of the bending part 5 and the inside of the bending part 5 are based on the bending point of the bending part 5, and the bending point here refers to the bending point in the bending part 5, not the junction point of the junction of the bending part 5 and the input end of the conveying channel 4, nor the junction point of the junction of the bending part 5 and the output end of the conveying channel 4, and the guide plate 2 outside the bending part 5 refers to the guide plate 2 deviating from the extension direction of the bending point of the bending part 5, and the guide plate 2 inside the bending part 5 refers to the guide plate 2 located on one side of the extension direction of the bending point of the bending part 5.

[0028] When the medicine bottle is conveyed through the conveying belt 1, the conveying belt 1 drives the medicine bottle to advance, and the medicine bottle gradually enters the conveying channel 4 in the advancing process; when the medicine bottle enters the bending part of the conveying channel 4, since the length occupied by the medicine bottle in the dumping state and the medicine bottle in the vertical state on the conveying belt 1 is different, and the gap between the lower surface of the guide plate 2 located outside the bending part 5 and the conveying surface of the conveying belt 1 is greater than the diameter of the medicine bottle and is less than the height of the medicine bottle, the medicine bottle in the dumping state cannot continue to keep consistent with the path of the conveying channel 4 when passing through the bending point of the bending part 5, while the medicine bottle in the vertical state continues to keep consistent with the path of the conveying channel 4 when passing through the bending point of the bending part 5; with the continuous conveying of the conveying belt 1, the medicine bottle in the dumping state completely separates from the conveying channel 4, and the medicine bottle in the dumping state is precisely removed.

[0029] In order to ensure that the medicine bottle in the dumping state can be completely removed, the bending surface on the guide surface 3 can be multiple, the bending part 5 on the conveying channel 4 can be multiple, and the length of the conveying channel 4 is longer, so that the medicine bottle in the dumping state can be completely rolled out; meanwhile, the input end of the conveying channel 4 is consistent with the conveying direction of the conveying belt 1, and the bending part 5 comprises an inclined section 51 and a straight section 52, one end of the inclined section 51 is connected with the input end of the conveying channel 4, the other end of the inclined section 51 extends to the edge of the conveying belt 1, and the straight section 52 is connected with the extension direction of the inclined section 51, and the extension direction of the straight section 52 is consistent with the conveying direction of the conveying belt 1; when the bending part 5 is multiple, the inclined section 51 in the next bending part 5 is connected with the straight section 52 in the previous bending part 5, and in order to avoid that the medicine bottle loses the conveying of the conveying belt 1 in the process of guiding the advancement through the conveying channel 4, the inclined directions of the inclined sections 51 in the adjacent two bending parts 5 are opposite, that is, the inclined section 51 in the previous bending part 5 and the inclined section 51 in the next bending part 5 are arranged in an "eight" shape. When the bending part 5 of the conveying channel 4 is multiple, the outside of the bending part 5 and the inside of the bending part 5 are taken as the reference of the bending point of the first bending part 5.

[0030] In the utility model, the included angle between the inclined section 51 and the straight section 52 in the bending part 5 is 105°-150°, preferably, the included angle between the inclined section 51 and the straight section 52 in the bending part 5 is 150° or 135°, which not only ensures that the medicine bottle in the vertical state can smoothly pass through the bending point of the bending part 5, but also ensures that the medicine bottle in the dumping state can completely deviate from the conveying channel 4 when passing through the bending point of the bending part 5, thereby avoiding the phenomenon that the medicine bottle in the vertical state is stuck when the medicine bottle in the dumping state is precisely removed.

[0031] In order to prevent the vertical state medicine bottle from being stuck when passing through the bending points, the bending points can be circular arc transition, so that the vertical state medicine bottle passes through the bending points more smoothly.

[0032] In order to make the medicine bottle in the pouring state completely discharge the conveying belt 1 when passing through the bending point of the bending section, the edge of the conveying belt 1 can be designed to correspond to the center line of the straight section 52 in the bending part 5, that is, when the medicine bottle in the pouring state and the vertical state medicine bottle passes through the bending point of the bending section and enters the straight section 52 in the bending part 5, only half of the medicine bottle is in contact with the conveying section of the conveying belt 1. In this process, the contact area between the vertical state medicine bottle and the conveying surface of the conveying belt 1 does not change during the conveying process, so that the vertical state medicine bottle can normally advance when passing through the straight section 52 in the bending part 5. The advancing direction of the medicine bottle in the pouring state is consistent with the extension direction of the inclined section 51 in the bending part 5, and the height of the medicine bottle is greater than the diameter of the medicine bottle, so that when the medicine bottle in the pouring state enters the bending point of the bending section, the part of the medicine bottle in the pouring state supported by the conveying surface of the conveying belt 1 is less than the part of the medicine bottle in the pouring state supported by the conveying surface of the conveying belt 1. At this time, the center of the medicine bottle in the pouring state is located outside the conveying surface of the conveying belt 1, and the continuous conveying of the conveying belt 1 makes the medicine bottle in the pouring state automatically discharge from the gap between the lower surface of the guide plate 2 inside the bending part 5 and the conveying surface of the conveying belt 1 when the medicine bottle in the pouring state automatically passes through the bending point of the bending part 5, avoiding that the medicine bottle in the pouring state remains on the conveying surface of the conveying belt 1.

[0033] In order to facilitate the collection of the rejected medicine bottles, a collection frame is arranged on the rack of the conveying belt 1 or the ground, and the collection frame corresponds to the conveying channel 4. Specifically, since the medicine bottle in the pouring state is discharged from the gap between the lower surface of the guide plate 2 inside the bending part 5 and the conveying surface of the conveying belt 1, the collection frame needs to be arranged to correspond to the gap between the lower surface of the guide plate 2 inside the bending part 5 and the conveying surface of the conveying belt 1, so as to ensure that the rejected medicine bottle can accurately enter the collection frame.

[0034] In order to ensure that the medicine bottle in the pouring state and the vertical state medicine bottle can enter the conveying channel 4, the two sides of the conveying belt 1 are provided with a blocking strip 7 connected with the two ends of the guide surface 3. The distance between the two blocking strips 7 on the two sides of the conveying belt 1 is matched with the diameter of the medicine bottle, and the distance between the lower end of the blocking strip 7 and the conveying surface of the conveying belt 1 is less than the diameter of the medicine bottle, so as to avoid that the medicine bottle rolls out from the two sides of the conveying belt 1 during the conveying process.

[0035] In the utility model, the conveying belt 1 selects the mesh belt conveyor.

[0036] When the medicine bottle needs to be conveyed, the medicine bottle enters the input end of the conveying belt 1, and through the conveying of the conveying belt 1, the medicine bottle enters the input end of the conveying channel 4, and the medicine bottle advances through the guidance of the conveying channel 4, with the continuous advancement of the medicine bottle, the medicine bottle enters the inclined section 51, and through the guidance of the inclined section 51, the position of the medicine bottle in the vertical state in the width direction of the conveying belt 1 changes, the medicine bottle in the dumping state is inclined relative to the conveying direction of the conveying belt 1, when the medicine bottle enters the bending point of the bending part 5, the medicine bottle in the vertical state smoothly enters the straight section 52, and the medicine bottle in the dumping state is discharged from the gap between the lower surface of the guide plate 2 inside the bending part 5 and the conveying surface of the conveying belt 1 and falls into the collecting frame, or the medicine bottle in the vertical state is discharged from the output end of the conveying belt 1 after entering the output end of the conveying channel 4 through the subsequent bending part 5 after passing through the straight section 52.
