Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical machinery, in particular to a round bottle supporting mechanism. Background Art

[0002] In the pharmaceutical industry, round bottles such as ampoules and vials are widely used. Due to the popularity of automated production, the production and inspection processes of round bottles have become automated. Round bottles need to be transported within and between various devices through transportation units. According to the requirements of different equipment or processes, the transportation of round bottles includes multiple states, such as transporting round bottles in a vertical or horizontal state.

[0003] For example, a Chinese utility model patent with authorization announcement number CN208902365 U discloses a rotary bottle leak detection device and a leak detection machine for use on a leak detection machine, the rotary bottle leak detection device includes a first guide rail for supporting the bottle body; a second guide rail for supporting the bottleneck; a rotating assembly for driving the bottle body to rotate; a conveying member arranged above the rotating assembly; a driving member for driving the rotating assembly to rotate; and a detection assembly arranged on the first guide rail and the second guide rail for detecting whether the bottle body is leaking; the rotating assembly includes a plurality of synchronous wheels arranged on the side of the first guide rail away from the second guide rail, a plurality of rollers located between the first guide rail and the second guide rail and corresponding to the number of the synchronous wheels, a plurality of connecting shafts, and a synchronous belt wound around the synchronous wheels and a driving wheel installed on the output shaft of the driving member, and the rollers are connected to the corresponding synchronous wheels through the connecting shaft.

[0004] At present, when conveying round bottles lying flat, the method in the above patent is used, in which the bottle body and the bottleneck are supported by two guide rails at the bottom respectively, and then the round bottle is pushed to move by the auger at the top. However, due to the different diameters of the body and the bottleneck of the round bottle, the distance moved by the round bottle rotating on the first guide rail and the second guide rail is the circumference of the bottle body, and the diameter of the bottleneck is obviously smaller than the diameter of the bottle body, that is, when the round bottle rotates one circle, the effective rolling stroke of the bottleneck on the guide rail is smaller than the moving stroke of the round bottle, and sliding friction will occur between the guide rail in contact with the bottleneck and the bottleneck, causing the guide rail in contact with the bottleneck to wear. If there is an error in the length of the body of the round bottle, the contact position of the guide rail and the bottleneck will change. Since the bottleneck is U-shaped, when the contact position of the guide rail and the bottleneck changes, it will cause one end of the head of the round bottle to tilt up. The greater the error in the length of the body of the round bottle, the higher the tilting angle will be. In this way, the round bottle will break when the auger contacts the round bottle. Since the auger is subjected to great force here, the groove of the auger here will wear. After wear, the broken bottle will be more serious.

[0005] Based on this, the utility model designs a circular bottle supporting bottle mechanism to solve the above problems. Utility Model Content

[0027] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0028] See also Figure 1-5 The utility model provides a technical solution: a round bottle supporting mechanism, comprising a support rail assembly and a driving unit for driving the round bottle to move, the support rail assembly comprising a bottle bottom support rail 1 and a bottle head support rail 2 which are parallel to each other, the bottle bottom support rail 1 and the bottle head support rail 2 are both provided with a lifting part for contacting the round bottle at the top, the lifting part of the bottle bottom support rail 1 and the lifting part of the bottle head support rail 2 are used to contact the bottle body of the round bottle at the same time to lift the round bottle, to ensure that the driving unit will not generate sliding friction with the lifting part when driving the round bottle to roll, to prevent the bottle bottom support rail 1 or the bottle head support rail 2 from wearing.

[0029] Specifically, the bottle bottom support rail 1 and the top of the bottle head support rail 2 form a lifting part, and both are in contact with the bottle body of the round bottle to lift the round bottle. The driving unit adopts a screw dragon, and the screw dragon is located above the round bottle to push the round bottle to move. The lifting parts formed on the top of the bottle bottom support rail 1 and the bottle head support rail 2 are preferably of the same height, so that the stability of the round bottle during rolling can be guaranteed to the greatest extent. However, due to errors in the production and assembly of parts, a height difference is allowed between the two lifting parts. The maximum allowable height difference varies according to the size of the round bottle and the size of the screw dragon. Since the body of the round bottle is cylindrical, the round bottle is used to contact the two lifting parts The diameters of the contact positions are the same, that is, no matter how many times the round bottle rolls on the two lifting parts, its rolling stroke on the two lifting parts is the same, and there will be no sliding friction between the round bottle and the lifting parts, which can reduce the wear on the lifting parts and extend the service life of the bottle head support rail 2 and the bottle bottom support rail 1. At the same time, no matter how large the error of the round bottle is in the length direction, as long as the length of the round bottle body is greater than the distance between the two lifting parts, the round bottle can be placed flat on the lifting parts at the top of the bottle bottom support rail 1 and the bottle head support rail 2. Slight errors will no longer cause the round bottle to tilt, reducing the possibility of the round bottle being squeezed and damaged by the auger, thereby extending the service life of the auger.

[0030] The device lifts the round bottle by the lifting part on the top of the bottle bottom rail 1 and the lifting part on the top of the bottle head rail 2, and the contact positions between the two lifting parts and the round bottle are both the bottle body of the round bottle. In this way, when the round bottle rolls on the two lifting parts during subsequent use, there will be no inconsistent rolling stroke, and there will be no sliding friction, thereby extending the service life of the bottle head rail 2 and the bottle bottom rail 1, and slight errors of the round bottle will not cause the round bottle to tilt as a whole, thereby preventing the auger from breaking and damaging the auger when the auger is driving the round bottle.

[0031] like Figure 5 As shown, the lifting portion is the top surface of the bottle bottom support rail 1 and the bottle head support rail 2, and the top surfaces of the bottle bottom support rail 1 and the bottle head support rail 2 are fixedly mounted with protrusions 3 to limit the axial movement of the round bottle.

[0032] In this embodiment, the top surface of the bottle head support rail 2 and the top surface of the bottle bottom support rail 1 are used as the lifting parts, and the round bottle is placed on the top surface of the bottle head support rail 2 and the bottom surface of the bottle bottom support rail 1. The protrusions 3 are fixedly installed on the top surfaces of the bottle head support rail 2 and the bottle bottom support rail 1, and the axial position of the round bottle is limited by the protrusions 3. The protrusions 3 on the bottle bottom support rail 1 can contact the bottom surface of the round bottle to place the round bottle toward the bottom surface. The protrusions 3 on the bottle head support rail 2 can contact the bottle head or the bottle shoulder to prevent the round bottle from moving toward the bottle head. The axial position of the round bottle is limited by the two protrusions 3 on the top surfaces of the bottle head support rail 2 and the bottle bottom support rail 1 to ensure the stability of the round bottle during rolling.

[0033] like Figure 4 As shown, the top of the side where the bottle bottom support rail 1 and the bottle head support rail 2 are close to each other is respectively provided with a first groove 11 and a second groove 21, the supporting portion is the bottom surface of the first groove 11 and the second groove 21, the side edge of the first groove 11 and the side edge of the second groove 21 are used to limit the axial movement of the round bottle, and the side edge of the second groove 21 is used to limit the position of the bottle shoulder, and a boss 22 is fixedly provided on the bottle head support rail 2, and the second groove 21 is provided on the top surface of the boss 22, so that the bottom surface of the second groove 21 is not lower than the top surface of the bottle head support rail 2.

[0034] In this embodiment, a first groove 11 and a second groove 21 are respectively provided on the top of the bottle bottom support rail 1 and the bottle head support rail 2, and the bottom surfaces of the first groove 11 and the second groove 21 serve as the lifting parts of the round bottle. When in use, the body of the round bottle is placed on the bottom surfaces of the first groove 11 and the second groove 21 respectively, and the axial movement of the round bottle is limited by the side edges of the first groove 11 and the second groove 21 to ensure the stability of the round bottle during rolling. The side edges of the first groove 11 can be used to limit the position of the bottle bottom, and the side edges of the second groove 21 can be used to limit the position of the bottle shoulder or the bottle head, so as to achieve the effect of preventing the axial movement of the round bottle. When the side edges of the second groove 21 are used to limit the shoulder of the round bottle, a boss 22 is provided on the top of the bottle head support rail 2, and the second groove 21 is provided on the surface of the boss 2, so that the bottom height of the second groove 21 is not lower than the top surface of the bottle head support rail 2 to prevent the bottle head from being lifted up by the bottle head support rail 2.

[0035] like Figure 3 As shown, the support rail assembly is installed on the adjustment assembly, and the adjustment assembly is used to adjust the height and spacing of the bottle bottom support rail 1 and the bottle head support rail 2. The adjustment assembly includes a vertical frame 4 fixed on the base, a first lead screw 41 vertically installed in the vertical frame 4 and capable of self-rotation, and a transverse frame 5 threadedly engaged with the first lead screw 41. The support rail assembly is installed on the transverse frame 5, and the first lead screw 41 is rotated to control the height of the transverse frame 5. The adjustment assembly also includes a second lead screw 51 horizontally installed in the transverse frame 5 and capable of self-rotation and a slide 52 threadedly engaged with the second lead screw 51. The bottle head support rail 2 is fixedly installed on the slide 52. A fixed platform 53 for installing the bottle bottom support rail 1 is also fixedly installed on the transverse frame, and the position of the bottle head support rail 2 is controlled by rotating the second lead screw 51.

[0036] Specifically, the height and spacing of the bottle bottom support rail 1 and the bottle head support rail 2 can be adjusted by the adjustment component to adapt to round bottles of different sizes. The adjustment component includes a vertical frame 4, a first screw 41 rotatably installed in the vertical frame 4, and a transverse frame 5 threadedly engaged with the first screw 41. The first screw 41 is vertically arranged and a first slide rail parallel to the first screw 41 is fixed in the vertical frame 4. The transverse frame 5 slides with the first slide rail, so that the height of the transverse frame 5 can be controlled by rotating the first screw 41. The bottle head support rail 2 and the bottle bottom support rail 1 are both installed on the transverse frame 5. The height of the transverse frame 5 can be controlled by rotating the first screw 41 to adjust the height of the transverse frame 5, so as to control the height of the bottle head support rail 2 and the bottle bottom support rail 1, thereby adjusting the spacing between the bottle head support rail 2 and the bottle bottom support rail 1 and the top auger, so as to adapt to round bottles of different diameters. There are a slide 52 and a fixed platform 53. The slide 52 is slidably set on the second slide rail inside the transverse frame 5, and the fixed platform 53 is directly fixed in the transverse frame 5. The slide 52 and the fixed platform 53 are respectively used to install the bottle head support rail 2 and the bottle bottom support rail 1, and the second screw 51 is rotatably installed in the transverse frame 5. The slide 52 is threadedly engaged with the second screw 51, and the second screw 51 is parallel to the second slide rail. By rotating the second screw 51, the slide 52 can be controlled to slide on the second slide rail. By adjusting the position of the slide 52, the bottle head slide rail installed on the slide 52 can be driven to move. The axial direction of the second slide rail is perpendicular to the axial direction of the bottle head support rail 2 and the axial direction of the bottle bottom support rail 1. In this way, when the slide 52 drives the bottle head support rail 2 to move along the axial direction of the second slide rail, the distance between the bottle head support rail 2 and the bottle bottom support rail 1 can be changed, so that the bottle head support rail 2 and the bottle bottom support rail 1 can adapt to round bottles of different lengths.

[0037] like Figure 3 As shown, a clamping block 6 is installed at one end of the vertical frame 4 and one end of the horizontal frame 5. The two clamping blocks 6 are used to clamp the first screw 41 and the second screw 51 respectively.

[0038] In this embodiment, the height and spacing of the bottle head support rail 2 and the bottle bottom support rail 1 can be adjusted respectively by rotating the first screw 41 and the second screw 51. In order to prevent the first screw and the second screw from rotating during operation, the first screw 41 and the second screw 51 are respectively clamped by two clamping blocks 6 during operation to ensure that the first screw 41 and the second screw 51 do not rotate during operation, thereby ensuring the stability of the bottle head support rail 2 and the bottle bottom support rail 1. The clamping blocks 6 are fastened to the vertical frame 4 and the horizontal frame 5 by bolts.

[0039] like Figure 1-2As shown, the entrance end of the rail assembly for the round bottles to enter is provided with a guide mechanism for guiding the round bottles, the guide mechanism includes a guide bevel 7 and a spring 8, the guide bevel 7 and the spring 8 are respectively arranged on both sides of the entrance end of the rail assembly, for locating the position of the round bottles, and the spring 8 is made of elastic material.

[0040] In this embodiment, a guide mechanism is provided at the inlet end of the rail assembly. The guide mechanism is a guide bevel 7 and a spring 8 respectively provided on both sides of the inlet end of the rail assembly. The round bottle is guided to enter the rail assembly in the correct position through the inclined design of the guide bevel 7 and the spring 8. The spring 8 is made of elastic material. The spring 8 is installed on the side of the bottle head rail 2 for squeezing the bottle head. The spring 8 is made of elastic material to prevent the bottle head from being squeezed and broken.

[0041] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
