Description

Technical Field

[0001] The utility model relates to the technical field of medicine filling, in particular to a detection mechanism and bottle washing equipment. Background Art

[0002] Pharmaceutical filling is a very important link in the production process of pharmaceutical preparations, which mainly involves filling drugs or reagents into containers for subsequent storage, transportation and use.

[0003] When the bottle washer is cleaning bottles used to fill medicines or drugs, the bottles move in a circle along the turntable under the clamping action of the mechanical claws, and the spray needle below makes a tracking motion and penetrates into the bottle up and down to wash the inner wall of the bottle.

[0004] The turntable of the existing bottle washing machine mechanical claw assembly adopts an internal gear meshing transmission structure. The turntable itself will cause certain wear on the tooth surface due to long-term operation. Although maintenance personnel will regularly replace easily worn parts such as the turntable as required, the actual wear of the mechanical claw assembly is difficult to accurately control. During the use of the equipment, the wear of the transmission mechanism of the mechanical claw assembly is still easy to cause the spray needle to collide with the bottle, thereby causing equipment downtime, production delays and cost waste. Utility Model Content

[0005] The utility model aims to provide a detection mechanism and bottle washing equipment, which are used to detect the wear state of the mechanical claw transmission mechanism, so as to prevent the problems such as the collision between the spray needle and the bottle, equipment downtime, production delay and cost waste caused by the wear of the turntable.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0008] A detection gear meshed with the rotating disk of the mechanical claw transmission mechanism, and an identification portion is provided on the end surface of the detection gear;

[0009] A switch assembly, the switch assembly comprising a detection switch, the detection switch being arranged opposite to the end surface of the detection gear with the identification portion, the turntable being able to drive the detection gear to rotate so that the identification portion triggers the detection switch, and the detection switch being used to record the time interval between two consecutive triggerings;

[0010] The working state includes a normal working state and an abnormal working state. When the time for the mechanical claw transmission mechanism to execute a working step is equal to the time interval, the mechanical claw transmission mechanism is in the normal working state; when the time for the mechanical claw transmission mechanism to execute a working step is not equal to the time interval, the mechanical claw transmission mechanism is in the abnormal working state.

[0011] As an optional solution for a detection mechanism, the detection gear is made of a self-lubricating plastic material.

[0012] As an optional solution of the detection mechanism, the identification part is a fastening bolt threaded on the detection gear, and the head of the fastening bolt protrudes from the end surface of the detection gear.

[0013] As an optional solution of the detection mechanism, the detection mechanism further includes a mounting base, and the detection gear is rotatably connected to the mounting base.

[0014] As an optional solution of the detection mechanism, a fixed shaft is vertically provided on the mounting base, and the detection gear is rotatably connected to the fixed shaft.

[0015] As an optional solution of a detection mechanism, a rolling bearing is provided between the detection gear and the fixed shaft.

[0016] As an optional solution of the detection mechanism, a retaining ring is sleeved on the fixed shaft, and the retaining ring is arranged at an end of the detection gear away from the mounting base, for axially limiting the detection gear.

[0017] As an optional scheme of the detection mechanism, the mounting base is a plate-shaped member, and a fastener passes through the bottom of the mounting base and is threadedly connected to an end of the fixed shaft away from the detection gear to fix the fixed shaft on the mounting base.

[0018] As an optional solution of a detection mechanism, the switch assembly further includes a switch seat, the detection switch is fixed on the switch seat, and the switch seat is fixed on the mounting base.

[0019] The bottle washing equipment comprises a mechanical claw transmission mechanism, a driving wheel and a support seat, wherein the turntable is arranged on the support seat, the driving wheel is meshed with the turntable for transmission, and the driving wheel is used to drive the turntable to rotate. The equipment also comprises a detection mechanism as described in any of the above schemes, and the detection mechanism is fixed on the support seat.

[0020] Beneficial effects:

[0021] First, the rotating disk of the mechanical claw transmission mechanism is arranged with multiple installation positions for placing bottles along the circumference. Under normal working conditions, the mechanical claw transmission mechanism performs a step, and the corresponding rotating disk rotates a preset angle. At this time, the bottle is just switched to be opposite to the spray needle. Under normal working conditions, the equipment can continue to operate normally. Correspondingly, under abnormal conditions, the equipment may have the risk of collision between the bottle and the spray needle, and timely adjustment is required to avoid this risk. By comparing the time for the mechanical claw transmission mechanism to perform a step with the time interval between two consecutive triggering of the detection switch, it is determined whether the state of the mechanical claw transmission mechanism is a normal working state or an abnormal working state. Specifically, by making the outer teeth of the detection gear match the inner teeth of the turntable, under normal working conditions, the time for the mechanical claw transmission mechanism to perform a step is just equal to the time for the detection gear to rotate one circle, and the identification part of the detection gear rotates one circle, and the time for the mechanical claw transmission mechanism to perform a step is also equal to the time interval for the identification part to trigger the detection switch twice in a row; under abnormal working conditions, due to the wear of the components inside the mechanical claw transmission mechanism, for example, the inner tooth surface of the turntable begins to wear, causing the original meshing state of the detection gear and the turntable to change, at this time The time interval for the identification part to trigger the detection switch twice in a row is not equal to the time for the mechanical claw transmission mechanism to perform a step. According to the wear state, this time interval may be less than the time for the mechanical claw transmission mechanism to perform a step, or it may be greater than the time for the mechanical claw transmission mechanism to perform a step. Through this mechanism, the wear state of the mechanical claw transmission mechanism can be detected at the early stage of wear. Within this initial time span, the equipment can continue to work, effectively preventing the accident of the spray needle and the bottle colliding due to the wear of the turntable, preventing equipment downtime and production delays, and saving costs at the same time.

[0022] Secondly, the bottle washing equipment equipped with this mechanism can effectively avoid the risk of collision between bottles and spray needles, improve the operating efficiency of the equipment, prevent equipment downtime, and save costs. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] Please see attached Figure 1 -Attached Figure 3The first aspect of the present embodiment relates to a detection mechanism (hereinafter referred to as "mechanism"), which is used to detect the working state of the mechanical claw transmission mechanism 100. Specifically, the mechanism includes a detection gear 1 and a switch assembly 2. The detection gear 1 is meshed with a rotating disk 110 of the mechanical claw transmission mechanism 100, and an identification portion 11 is provided on the end surface of the detection gear 1; the switch assembly 2 includes a detection switch 21, and the detection switch 21 is arranged opposite to the end surface of the detection gear 1 with the identification portion 11. The rotating disk 110 can drive the detection gear 1 to rotate so that the identification portion 11 triggers the detection switch 21, and the detection switch 21 is used to record the time interval between two consecutive triggerings; the working state includes a normal working state and an abnormal working state. When the time for the mechanical claw transmission mechanism 100 to perform a step is equal to the time interval, the mechanical claw transmission mechanism 100 is in a normal working state; when the time for the mechanical claw transmission mechanism 100 to perform a step is not equal to the time interval, the mechanical claw transmission mechanism 100 is in an abnormal working state.

[0036] In this embodiment, the turntable 110 of the mechanical claw transmission mechanism 100 is arranged along the circumference with multiple installation positions for placing bottles. Under normal working conditions, the mechanical claw transmission mechanism 100 performs a working step, and the corresponding turntable 110 rotates a preset angle. At this time, the bottle is switched to be opposite to a certain spray needle 400, so as to facilitate the spray needle 400 to penetrate into the bottle for cleaning. Under normal working conditions, the equipment can continue to operate normally. For example, each bottle rotates 6° to complete a cleaning task, that is, the preset angle of rotation of the turntable 110 is 6°. Accordingly, under abnormal conditions, the equipment may have the risk of collision between the bottle and the spray needle 400, and timely adjustment is required to avoid this risk.

[0037] This embodiment compares the time it takes for the mechanical claw transmission mechanism 100 to execute a step with the time interval between two consecutive triggerings of the detection switch 21, so as to determine whether the state of the mechanical claw transmission mechanism 100 is a normal working state or an abnormal working state. Specifically, by making the outer teeth of the detection gear 1 cooperate with the inner teeth of the turntable 110, under an ideal working state, the time it takes for the mechanical claw transmission mechanism 100 to execute a step should be exactly equal to the time it takes for the detection gear 1 to rotate one circle, that is, the recognition part 11 of the detection gear 1 rotates one circle, and the time it takes for the mechanical claw transmission mechanism 100 to execute a step is also equal to the time interval between two consecutive triggerings of the detection switch 21 by the recognition part 11. Of course, the coordination of the mechanism is within a certain error range. Therefore, within the allowable range of the time error, the time interval between two consecutive triggerings of the detection switch 21 can float within a small range of tolerance. That is to say, when the time interval does not exceed When the mechanical claw transmission mechanism 100 is within the preset range, it can also indicate that the entire mechanism is still in a normal working state; in an abnormal working state, due to the wear of the components inside the mechanical claw transmission mechanism 100, for example, the inner teeth of the turntable 110 begin to wear, causing the original meshing state of the detection gear 1 and the turntable 110 to change. At this time, the time interval between the identification unit 11 triggering the detection switch 21 twice in a row is not equal to the time for the mechanical claw transmission mechanism 100 to perform a step. According to the wear state, the time interval may be less than the time for the mechanical claw transmission mechanism 100 to perform a step, or it may be greater than the time for the mechanical claw transmission mechanism 100 to perform a step. Of course, if the mechanism does not meet the allowable error range of the time interval between triggering the detection switch 21 twice in a row, it means that the inner teeth of the turntable 110 have not only worn but also reached the predicted limit, and continuing to work is likely to cause a collision accident.

[0038] It should be noted that when an abnormal working state occurs, that is, by judging that the time interval for the detection gear 1 to complete a circle has changed significantly, this change may be ahead of or behind the time it takes for the mechanical claw transmission mechanism 100 to actually execute a work step. For example, when the time difference between the advance or lag time and a work step is more than 1s, it is judged that the time interval for the detection gear 1 to complete a circle has changed significantly. Therefore, it can be determined that a certain amount of wear has occurred inside the mechanical claw transmission mechanism 100, and maintenance personnel are required to promptly maintain or replace key parts in the equipment.

[0039] This mechanism can complete the detection of the wear status of the mechanical claw transmission mechanism 100 at the early stage of wear. During this initial time span, the equipment can continue to work, which can effectively prevent the spray needle 400 from colliding with the bottle due to the wear of the turntable 110, prevent equipment downtime and production delays, and save costs at the same time. In addition, this mechanism can not only detect the wear problem of the mechanical claw transmission mechanism 100, but also further determine whether there is a problem in the assembly process of the mechanical claw transmission mechanism 100 at the early stage of product assembly.

[0040] In this embodiment, the turntable 110 is driven by a servo motor, and the rotation speed of the servo motor is controlled by a pulse signal of a PLC (Programmable Logic Controller). The rotation speed of the servo motor determines the time it takes for the mechanical claw transmission mechanism 100 to complete a step. Therefore, by manually setting in advance, the rotation speed of the servo motor remains unchanged, and the time it takes for the mechanical claw transmission mechanism 100 to complete a step also remains unchanged. Under normal working conditions, the mechanical claw transmission mechanism 100 is free of wear, and the time it takes for the mechanical claw transmission mechanism 100 to complete a step is always equal to the time interval for the detection switch 21 to receive a signal; once the mechanical claw transmission mechanism 100 is worn, the wear state causes the time interval for the detection switch 21 to receive a signal to change, and thus causes the time it takes for the mechanical claw transmission mechanism 100 to complete a step to no longer be equal to the time interval for the detection switch 21 to receive a signal. After the maintenance personnel obtain the signal, they can further replace or adjust the parts to avoid the risk of collision between the bottle and the spray needle 400 in time, thereby ensuring continuous production of the equipment.

[0041] Optionally, the detection gear 1 is made of self-lubricating plastic material.

[0042] In the present embodiment, the meshing teeth of the detection gear 1 and the turntable 110 are designed to have no displacement, that is, the pitch circle and the pitch circle are equal, and the number of teeth passed by the mechanical claw transmission mechanism 100 in completing a working step is equal to the number of teeth of the detection gear 1. Usually, the tooth surface of the meshing gear teeth is prone to wear, so the meshing gears need to be replaced after a certain working time. The general design principle is that the hardness of the small gear is greater than that of the large gear. However, considering that it is easier to disassemble the detection gear 1 on the bottle washing equipment than to disassemble the turntable 110, the hardness of the detection gear 1 is less than that of the detection gear 1; in the present embodiment, the detection gear 1 is made of self-lubricating plastic material. During the meshing transmission of the detection gear 1 and the turntable 110, the self-lubricating performance improves the transmission smoothness and life of the detection gear 1, and can further avoid the application of grease or lubricating oil in the meshing area to cause bottle contamination.

[0043] Optionally, the identification portion 11 is a fastening bolt threadedly connected to the detection gear 1 , and the head of the fastening bolt protrudes from the end surface of the detection gear 1 .

The fastening bolt is screwed into the threaded hole, and the head of the fastening bolt is made to protrude from the end face of the detection gear 1 so that the head of the fastening bolt presses against the detection switch 21. Of course, technicians in this field can adaptively adjust the position of the identification part 11 according to the position of the detection switch 21.

[0045] Optionally, the mechanism further includes a mounting base 3 , and the detection gear 1 is rotatably connected to the mounting base 3 .

[0046] In this embodiment, the mounting base 3 is used to provide a mounting position for the detection gear 1 .

[0047] Furthermore, a fixed shaft 31 is vertically provided on the mounting base 3 , and the detection gear 1 is rotatably connected to the fixed shaft 31 .

[0048] One end of the fixed shaft 31 is fixed on the mounting base 3, and the other end is rotatably connected to the detection gear 1. The detection gear 1 and the fixed shaft 31 are connected via a rolling bearing 32. Since the detection gear 1 is basically not subjected to axial force, two deep groove ball bearings can be selected for the rolling bearing 32. The rolling bearing 32 is installed by setting a corresponding step on the detection gear 1.

[0049] Furthermore, a retaining ring 33 is sleeved on the fixed shaft 31 . The retaining ring 33 is arranged at one end of the detection gear 1 away from the mounting base 3 , and is used to limit the axial position of the detection gear 1 .

[0050] In this embodiment, the fixed shaft 31 is a stepped shaft, and the small diameter end of the fixed shaft 31 is connected to the detection gear 1. One end of the detection gear 1 is arranged on the end face of the large diameter end of the fixed shaft 31, and the other end is completely limited on the fixed shaft 31 by a retaining ring 33.

[0051] Optionally, the mounting base 3 is a plate-shaped member, and the fastener 34 passes through the bottom of the mounting base 3 and is threadedly connected to an end of the fixed shaft 31 away from the detection gear 1 , so that the fixed shaft 31 is fixed on the mounting base 3 .

[0052] In this embodiment, the fastener 34 is a screw, and a through hole is provided on the mounting base 3. The screw passes through the through hole and is threadedly connected to one end of the fixed shaft 31 to fix the fixed shaft 31 on the mounting base 3. The threaded connection method is simple and convenient.

[0053] Optionally, the switch assembly 2 further includes a switch seat 22 , the detection switch 21 is fixed on the switch seat 22 , and the switch seat 22 is fixed on the mounting base 3 .

[0054] In this embodiment, the switch seat 22 is a sheet metal part arranged vertically and having a through hole on the top, and the detection switch 21 is opposite to the through hole.

[0055] The second aspect of the present embodiment also relates to a bottle washing device, which includes a mechanical claw transmission mechanism 100, a driving wheel 200, a support seat 300 and the above detection mechanism. Among them, the turntable 110 is arranged on the support seat 300, the driving wheel 200 is meshed with the turntable 110 for transmission, the driving wheel 200 is used to drive the turntable 110 to rotate, and the detection mechanism is fixed on the support seat 300.

[0056] The support base 300 is used to provide support for the detection assembly, the mechanical claw transmission mechanism 100 and the driving wheel 200. The driving wheel 200 is connected to the driving end of the servo motor to drive the turntable 110 to rotate, and the mounting base 3 of the detection mechanism is screwed to the support base 300.

[0057] The bottle washing equipment equipped with this mechanism can effectively avoid the risk of collision between the bottle and the spray needle 400, improve the operating efficiency of the equipment, prevent equipment downtime, and save costs.
