A bottle separating screw and a bottle separating device

Abstract

The application discloses a bottle separating screw and a bottle separating device. The screw thread of the bottle separating screw forms a spiral groove. The bottle separating screw comprises a taper thread section L1 and a column thread section L2 which are fixedly connected and serve as the bottle entering end and the bottle discharging end of the bottle separating screw respectively. The width and the depth of the spiral groove of the taper thread section L1 gradually increase until they are equal to the width and the depth of the spiral groove of the column thread section L2 respectively. The width of the spiral groove of the column thread section L2 matches the outer diameter of the medicine bottle, and the depth matches the radius of the medicine bottle. By setting the bottle separating screw as the taper thread section L1 and the column thread section L2 which are fixedly connected, and by making the width of the taper thread section L1 smaller than the outer diameter of the medicine bottle, a single medicine bottle can smoothly enter the spiral groove of the taper thread section L1, so that the phenomenon of bottle extrusion caused by multiple medicine bottles simultaneously extruding into one spiral groove can be avoided.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medicine bottle conveying, in particular to a bottle separating screw and a bottle separating device. BACKGROUND

[0002] In the medicine bottle labeling production line, it is usually necessary to convey the medicine bottles at a certain interval. The bottle separating screw, as a member of the conveying equipment, has the main function of separating the medicine bottles by a certain distance through power rotation to achieve the purpose of precise positioning and labeling. The patent with the application number 202211168009.4 discloses a bottle separating screw and a bottle separating mechanism. The bottle separating screw comprises a screw body, the screw thread of the screw body is composed of an equal pitch section at the front side and a variable pitch section at the rear side, the equal pitch section contains at least two equal pitch screw threads, the thread of the screw thread is a sharp thread, and the pitch of the variable pitch section gradually increases from front to back. The bottle separating mechanism comprises the bottle separating screw and a track block arranged in parallel with the bottle separating screw.

[0003] Since the bottles are arranged in a single row, they are not arranged in a straight row, but are slightly staggered to the two sides, so that the distance between the adjacent bottles along the axial direction of the screw is less than the outer diameter of the bottle. Since the width of the screw groove is generally matched with the outer diameter of the bottle, at this time, two bottles may be squeezed into one screw groove, which may cause bottle jamming or even breakage of the bottles due to squeezing.

[0004] In the prior art, a screw with a smaller width screw groove is selected to solve the above problems. However, since the cross section of the screw groove is generally arc-shaped, when the width is small, the depth of the screw groove will be shallow (the height of the screw thread will be low). When separating the bottles, the screw thread needs to provide a pushing force to the bottles to move them forward. Since the bottle is cylindrical, when the screw thread pushes the bottle forward, it will inevitably generate a pressure on the bottle towards the track block, which will increase the friction between the bottle and the track block and cause wear of the bottle. SUMMARY

[0005] The present application aims to overcome the above technical deficiencies and provide a bottle separating screw and a bottle separating device to solve the technical problems that, in the prior art, two bottles may be squeezed into one screw groove when the bottle separating screw is used, which may cause bottle jamming, and when the bottle separating screw pushes the bottles forward, it will inevitably generate a pressure on the bottle towards the track block, which will increase the friction between the bottle and the track block and cause wear of the bottle.

[0008] Further, the thread starting end of the taper thread section L1 has a point.

[0009] Further, the width of the outermost spiral groove of the taper thread section L1 does not exceed 2 / 3 of the outer diameter of the medicine bottle.

[0011] Further, the bottle separating device further comprises a rack, the bottle separating screw is rotatably arranged on the rack, and the driving mechanism is fixedly arranged on the rack and has its output end in transmission or fixed connection with one end of the bottle separating screw.

[0023] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0024] The present application provides a bottle separating screw, the structure of which is shown in Figure 1 The helical groove 101 is formed between the threads 102 of the bottle separating screw 1, the bottle separating screw 1 comprises a taper thread segment L1 and a column thread segment L2 as the bottle entering end and the bottle discharging end of the bottle separating screw respectively, and the taper thread segment L1 and the column thread segment L2 are fixedly connected.

[0025] The width and depth of the helical groove 101 of the taper thread segment L1 gradually increase until they are equal to the width and depth of the helical groove 101 of the column thread segment L2, respectively, the width of the helical groove 101 of the column thread segment L2 matches the outer diameter of the medicine bottle, and the depth matches the radius of the medicine bottle; specifically, the width of the outermost helical groove 101 of the taper thread segment L1 is not more than 2 / 3 of the outer diameter of the medicine bottle.

[0026] By setting the bottle separating screw 1 as the taper thread segment L1 and the column thread segment L2 fixedly connected as the bottle entering end and the bottle exiting end of the bottle separating screw 1 respectively, and gradually increasing the width and depth of the helical groove 101 of the taper thread segment L1 until they are equal to the width and depth of the helical groove 101 of the column thread segment L2, respectively, the width of the taper thread segment L1 is less than the outer diameter of the medicine bottle, so that a single medicine bottle can smoothly enter the helical groove 101 of the taper thread segment L1, to avoid the squeezing bottle phenomenon when multiple medicine bottles are squeezed into one helical groove 101 at the same time; meanwhile, the width of the helical groove 101 of the column thread segment L2 matches the outer diameter of the medicine bottle, which can improve the precision of bottle separation, and the depth matches the radius of the medicine bottle, so that the medicine bottle can obtain the parallel axial thrust exerted by the bottle separating screw 1, to avoid the medicine bottle being damaged due to the oblique thrust caused by the shallow depth of the helical groove 101.

[0027] In order to facilitate the separation of a medicine bottle from a row of closely arranged medicine bottles, as a preferred embodiment, the thread 102 of the taper thread segment L1 has a tooth tip 110 at the starting end.

[0028] It can be understood that the tooth tip 110 can be squeezed from two closely arranged medicine bottles, and the separation of the medicine bottles can be realized by rotating the bottle separating screw 1.

[0029] The application also provides a bottle separating device, as shown in Figure 2 the drawings, comprising the bottle separating screw 1, the conveying line 2, the blocking strip 3 and the driving mechanism 4, wherein the lead of the thread 102 at the bottle entering end of the bottle separating screw 1 is less than the lead of the thread 102 at the bottle exiting end, the bottle separating screw 1 is rotatably arranged on one side above the conveying line 2, the blocking strip 3 is fixedly arranged on the other side above the conveying line 2, and the bottle separating channel 20 is formed between the bottle separating screw 1 and the blocking strip 3 and above the conveying line 2; the output end of the driving mechanism 4 is in transmission or fixed connection with one end of the bottle separating screw 1, for driving the bottle separating screw 1 to rotate, so as to drive the medicine bottle in the bottle separating channel 20 to move at the same speed as the conveying line 2.

[0030] It can be understood that when the driving mechanism 4 drives the bottle separating screw 1 to rotate, the bottle separating screw 1 can separate the bottle closest to the bottle separating screw 1 from other bottles, and the bottle can be pushed to move synchronously with the conveying line 2, and because the pitch of the screw thread 102 at the bottle entering end is smaller than that at the bottle discharging end, the distance between the bottles gradually increases when the bottles move, thereby achieving the bottle separating action.

[0031] Please continue to refer to Figure 2 , specifically, the bottle separating device further comprises a rack 5, the bottle separating screw 1 is rotatably arranged on the rack 5, and the driving mechanism 4 is fixedly arranged on the rack 5 and is in transmission or fixed connection with one end of the bottle separating screw 1.

[0032] Further, the driving mechanism 4 comprises a reducer 41 and a motor 42, both of which are detachably arranged on the rack 5, and the input end of the reducer 41 is in fixed connection with the output shaft of the motor 42, and the output end of the reducer 41 is in transmission connection with one end of the bottle separating screw 1.

[0033] In order to achieve the transmission connection between the reducer 41 and the bottle separating screw 1, as a preferred embodiment, the driving mechanism 4 further comprises a transmission sleeve 43, one end of the transmission sleeve 43 is in fixed connection with the output end of the reducer 41.

[0034] The bottle separating screw 1 comprises a fixedly connected screw rod 11 and a connecting rod 12, the connecting rod 12 can be inserted into the transmission sleeve 43 to achieve the transmission connection between the screw rod 11 and the output end of the reducer 41. As a specific embodiment, the rack 5 is provided with a mounting hole (not shown in the figure), and the end of the screw rod 11 away from the connecting rod 12 is fixedly provided with a connecting shaft matched with the mounting hole. When the bottle separating screw 11 is installed, the connecting rod 12 can be first inserted into the transmission sleeve 43, and then the connecting shaft is installed in the mounting hole, thereby achieving the quick installation and replacement of the bottle separating screw 11.

[0035] It can be understood that by fixing the transmission sleeve 43 to the output end of the reducer 41 and arranging the bottle separating screw 1 as a fixedly connected screw rod 11 and a connecting rod 12, the screw rod 11 can be inserted into the transmission sleeve 43 to achieve the transmission connection with the reducer 41.

[0036] As a preferred embodiment, the driving mechanism 4 further comprises an elastic member (not shown in the figure), which is fixedly arranged in the interior of the transmission sleeve 43 and cooperates with the rack 5 to avoid the axial movement of the bottle separating screw 1. Specifically, the elastic member is a spring.

[0037] It can be understood that, by fixing the elastic member in the transmission sleeve 43, the size allowance is reserved in the transmission sleeve 43 by the stretchability of the elastic member, thereby facilitating the quick installation and replacement of the bottle separating screw 1.

[0038] In order to enable the width of the bottle separating channel 20 to be adjusted according to the outer diameter of the medicine bottle, as a preferred embodiment, the bottle separating device further comprises a telescopic driving mechanism 6, the output end of the telescopic driving mechanism 6 being fixedly connected with the blocking strip 3, for driving the blocking strip 3 to move close to or away from the bottle separating screw 1, so as to adjust the width of the bottle separating channel 20; specifically, the telescopic driving mechanism 6 is a pneumatic cylinder, a hydraulic cylinder or an electric push rod.

[0039] In order to facilitate the understanding of the present application, the following will be described in combination with Figure 1 and Figure 2 The working principle of the present scheme will be described in detail:

[0040] In operation, the motor 42 is turned on to drive the bottle separating screw 1 to rotate; the medicine bottles are closely arranged in a column on the conveying line 2 for conveying, when the frontmost medicine bottle is conveyed to the bottle entering end of the bottle separating screw 1, the tooth tip 110 can be squeezed into the space between the frontmost two medicine bottles to separate the frontmost medicine bottle to enter the spiral groove 101.

[0041] With the rotation of the bottle separating screw 1, the thread 102 pushes the medicine bottle in the spiral groove 101 to move forward; since the pitch of the thread 102 at the bottle entering end of the bottle separating screw 1 is smaller than that of the thread 102 at the bottle exiting end, the distance between the medicine bottles in the spiral groove 101 gradually increases, thereby achieving the purpose of separating the medicine bottles.

[0042] When it is necessary to replace the bottle separating screw 1, the screw rod 11 can be held and moved towards the transmission sleeve 43 to squeeze the elastic member, at this time, the other end of the screw rod 11 can be taken off from the rack 5 (this operation is similar to the replacement of the battery in a remote control device).

[0043] The specific embodiments of the present application described above do not constitute a limitation on the protection scope of the present application. Any various other corresponding changes and modifications made according to the technical concept of the present application shall be included in the protection scope of the claims of the present application.
