Description

Technical Field

[0001] This utility model relates to the field of irregular-shaped bottle technology, and in particular, to an irregular-shaped bottle feeding device. Furthermore, this utility model also relates to a detection device having the aforementioned irregular-shaped bottle feeding device. Background Technology

[0002] When using a vacuum decay leak detection device, the bottles arranged sequentially on the bottle inlet track need to be separated into individual bottles at a certain distance for testing in a relatively independent manner.

[0003] In existing technologies, standard-shaped round bottles (such as ampoules, oral liquid bottles, and vials) are usually separated using an auger (also known as a screw) and then fed into the testing area individually by a bottle feeding wheel.

[0004] However, some non-circular, irregularly shaped bottles also exist in the existing technology. These irregularly shaped bottles cannot currently be separated and transported for independent inspection using existing conventional devices. Utility Model Content

[0005] This utility model provides a bottle feeding device for irregularly shaped bottles and a detection device with the same, so as to solve the technical problem in the prior art that irregularly shaped bottles cannot be separated and transported for independent detection using conventional devices.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A bottle feeding device for irregularly shaped bottles includes: a frame, and a conveying device, a bottle clamping device, a photoelectric detection component, a bottle feeding wheel, and a control device mounted on the frame. The conveying device, the bottle clamping device, the photoelectric detection component, and the bottle feeding wheel are respectively connected to the control device. The conveying device is used to convey groups of irregularly shaped bottles to be detected forward in sequence. The bottle feeding wheel is connected to the output end of the conveying device. The bottle clamping device and the photoelectric detection component are respectively mounted in the conveying path of the conveying device. The photoelectric detection component is used to detect whether any groups of irregularly shaped bottles have passed through at set positions. The bottle clamping device is used to clamp or release the passing groups of irregularly shaped bottles according to the detection results of the photoelectric detection component, so that the groups of irregularly shaped bottles enter the bottle feeding wheel in a single-group, interval-wise manner. The bottle feeding wheel is used to convey the groups of irregularly shaped bottles that enter in a single group forward in a sequential, interval-wise manner.

[0008] Furthermore, the conveying device includes a conveyor belt for conveying irregularly shaped bottle groups, and two limiting rails disposed on both sides of the conveyor belt along the length of the conveyor belt. The two limiting rails work in conjunction with the conveyor belt to ensure that the irregularly shaped bottle groups on the conveyor belt are conveyed forward in sequence. The bottle clamping device and photoelectric detection component are respectively disposed on the conveying path of the conveyor belt.

[0009] Furthermore, the bottle clamping device includes a first clamping mechanism located near the output end of the conveyor belt. The first clamping mechanism is used to clamp or release the clamped irregular bottle group under the action of the control device. The photoelectric detection component includes two sets of first photoelectric switches that work together. The two sets of first photoelectric switches are located on both sides of the first clamping mechanism to detect whether there is an irregular bottle group passing upstream and downstream of the first clamping mechanism.

[0010] Furthermore, the bottle clamping device also includes multiple sets of second clamping mechanisms arranged sequentially at intervals along the conveying direction of the conveyor belt. The second clamping mechanisms are located upstream of the first clamping mechanisms to clamp or release the passing irregularly shaped bottle groups under the action of the control device. The photoelectric detection component also includes multiple sets of second photoelectric switches corresponding to each second clamping mechanism. Each set of second photoelectric switches is located downstream of the corresponding second clamping mechanism to detect whether an irregularly shaped bottle group has passed through the set position.

[0011] Furthermore, the first clamping mechanism and the second clamping mechanism have the same structure, both including a servo motor mounted on the frame, a transmission screw connected to the output end of the servo motor, and two clamping blocks that cooperate to clamp the passing irregular bottle group; the outer circles at both ends of the transmission screw are respectively machined with external threads in opposite directions; the two clamping blocks are respectively threaded through the outer circles at both ends of the transmission screw.

[0012] Furthermore, the irregularly shaped bottle feeding device also includes a mounting plate disposed on the frame and located above the conveyor belt; two sets of first photoelectric switches and multiple sets of second photoelectric switches are arranged sequentially at intervals along the extension direction of the mounting plate to detect irregularly shaped bottle groups whose height is lower than the limit fence; or, two sets of first photoelectric switches and multiple sets of second photoelectric switches are arranged sequentially at intervals along the outer side of the limit fence, and through holes are provided on the limit fence corresponding to the first and second photoelectric switches.

[0013] Furthermore, the bottle feeding wheel includes a rotating wheel body and a bottle feeding grid surrounding the outer side of the wheel body; the outer periphery of the wheel body is machined with recessed grooves arranged sequentially along the circumference, the grooves are used to feed a group of irregularly shaped bottles from the conveyor belt outlet into the grooves during the rotation of the wheel body, and at the same time cooperate with the bottle feeding grid to confine the irregularly shaped bottles in the grooves so that they move forward with the wheel body.

[0014] Furthermore, the shape of the dial groove is adapted to the shape of the irregular bottle group; the dial wheel body is detachably fixed to the frame, so that dial wheel bodies with different dial grooves can be replaced to correspond to irregular bottle groups with different shapes.

[0015] Furthermore, the irregular bottle group includes a single irregular bottle, or a group of irregular bottles connected in sequence.

[0016] According to another aspect of the present invention, a detection device is also provided, having a bottle feeding device for irregularly shaped bottles as described in any of the above.

[0017] This utility model has the following beneficial effects:

[0018] When using the irregular-shaped bottle feeding device of this utility model, the irregular-shaped bottles supplied from upstream first enter the conveying device in sequence. Under the action of the conveying device, they are arranged sequentially and conveyed forward (in actual operation, the output of the downstream conveying device is higher than that of the upstream device, so that the irregular-shaped bottle groups are arranged sequentially and at intervals in the conveying device, and the spacing is also related to the output of the conveying device and the output of the upstream device). At this time, the photoelectric detection component detects whether there is an irregular-shaped bottle group at its respective setting position and feeds the detection information back to the control device. After receiving the detection information, the control device correspondingly causes the bottle clamping device to clamp the bottle, which is about to pass through. The device can handle the loading of irregularly shaped bottles, either by clamping the penultimate group of irregularly shaped bottles or by releasing the already clamped group. For example, by clamping the penultimate group of irregularly shaped bottles, the last group of bottles can be moved individually into the loading wheel. Once the last group of bottles approaches or enters the loading wheel, the clamping device can release the penultimate group of irregularly shaped bottles, allowing them to move individually into the loading wheel. This achieves the purpose of separating and transporting irregularly shaped bottles for subsequent independent inspection, thus solving the technical problem of not being able to independently inspect non-circular irregularly shaped bottle groups in existing technologies. Furthermore, the entire loading device has a simple structure, a simple operating principle, and low manufacturing cost.

[0019] The detection device of this utility model allows irregularly shaped bottle groups to enter the bottle feeding wheel separately, so as to separate and transport the irregularly shaped bottle groups for subsequent independent detection. This solves the technical problem that the existing technology cannot independently detect non-circular irregularly shaped bottle groups. Moreover, the entire bottle feeding device has a simple structure, simple operating principle, and low manufacturing cost.

[0020] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0034] Reference Figure 1-3 A preferred embodiment of this utility model provides a bottle feeding device for irregularly shaped bottles, including: a frame, and a conveying device 1, a bottle clamping device 2, a photoelectric detection component, a bottle feeding wheel 4, and a control device disposed on the frame. The conveying device 1, the bottle clamping device 2, the photoelectric detection component, and the bottle feeding wheel 4 are respectively connected to the control device. The conveying device 1 is used to convey the irregularly shaped bottle groups 5 to be detected forward in sequence. The bottle feeding wheel 4 is connected to the output end of the conveying device 1. The bottle clamping device 2 and the photoelectric detection component are respectively disposed in the conveying path of the conveying device 1. The photoelectric detection component is used to detect whether irregularly shaped bottle groups 5 have passed through at each set position. The bottle clamping device 2 is used to clamp or release the passing irregularly shaped bottle groups 5 according to the detection result of the photoelectric detection component, so that the irregularly shaped bottle groups 5 enter the bottle feeding wheel 4 in a single-group interval sequence. The bottle feeding wheel 4 is used to convey the irregularly shaped bottle groups 5 that enter in a single group forward in sequence at intervals.

[0035] When using the irregularly shaped bottle feeding device of this utility model, the irregularly shaped bottle group 5 supplied from the upstream first enters the conveying device 1 in sequence, and is arranged sequentially and conveyed forward under the action of the conveying device 1 (in actual operation, the output of the downstream conveying device 1 is made higher than that of the upstream device, so that the irregularly shaped bottle group 5 is arranged sequentially and at intervals in the conveying device 1, and the spacing is also related to the output of the conveying device 1 and the output of the upstream device). At this time, the photoelectric detection component detects whether there is an irregularly shaped bottle group 5 at its respective setting position and feeds back the detection information to the control device. After receiving the detection information, the control device accordingly causes the bottle clamping device 2 to clamp the bottle about to pass. The irregularly shaped bottle group 5 is either released or the already clamped irregularly shaped bottle group 5 is released. That is, the bottle clamping operation of the bottle clamping device 2 is used to clamp the second to last irregularly shaped bottle group 5, so that the last irregularly shaped bottle group 5 enters the bottle feeding wheel 4 alone. After the last irregularly shaped bottle group 5 approaches or enters the bottle feeding wheel 4, the clamping device 2 is released to allow the irregularly shaped bottle group 5 to enter the bottle feeding wheel 4 alone. This achieves the purpose of separating and conveying the irregularly shaped bottle group 5 for subsequent independent inspection, thereby solving the technical problem in the prior art that it is impossible to independently inspect non-circular irregularly shaped bottle groups 5. Moreover, the entire bottle feeding device has a simple structure, simple operating principle, and low manufacturing cost.

[0036] Optionally, the irregularly shaped bottle group 5 includes a single irregularly shaped bottle, such as Figure 1 As shown, or including multiple irregularly shaped bottles connected in sequence, such as Figure 2 As shown.

[0037] Optionally, such as Figure 4 As shown, the conveying device 1 includes a conveyor belt 11 for conveying irregularly shaped bottle groups 5, and two limiting rails 12 disposed on both sides of the conveyor belt 11 along its length. The two limiting rails 12 cooperate with the conveyor belt 11 to ensure that the irregularly shaped bottle groups 5 on the conveyor belt 11 are conveyed forward in sequence. In actual installation, the arrangement of the two limiting rails 12 ensures the sequential order of the irregularly shaped bottle groups 5. At the same time, by setting the conveying speed of the conveyor belt 11, the irregularly shaped bottle groups 5 entering the conveyor belt 11 from the upstream device are arranged sequentially at intervals on the conveyor belt 11 to facilitate the clamping operation of the subsequent bottle clamping device 2. The bottle clamping device 2 and the photoelectric detection component are respectively disposed on the conveying path of the conveyor belt 11.

[0038] Optionally, such as Figure 3 and Figure 4As shown, the bottle clamping device 2 includes a first clamping mechanism 21 located near the output end of the conveyor belt. The first clamping mechanism 21 is used to clamp or release the irregularly shaped bottle group 5 under the action of the control device. The photoelectric detection component includes two sets of first photoelectric switches that work together. The two sets of first photoelectric switches are located on both sides of the first clamping mechanism 21 to detect whether there is an irregularly shaped bottle group 5 passing upstream and downstream of the first clamping mechanism 21. In this optional scheme, the first photoelectric switch located downstream is photoelectric switch 1A, and the first photoelectric switch located upstream is photoelectric switch 2A. During operation, when photoelectric switch 1A detects the first group of irregularly shaped bottles 5, if the first clamping mechanism 21 has a second group of irregularly shaped bottles 5 passing through, when photoelectric switch 2A detects the second group of irregularly shaped bottles 5, the information is fed back to the control device. The control device causes the first clamping mechanism 21 to clamp the second group of irregularly shaped bottles 5, and the second group of irregularly shaped bottles 5 stops moving and becomes stationary. The first group of irregularly shaped bottles 5 continues to move and enters the bottle feeding wheel 4. After the first group of irregularly shaped bottles 5 moves and leaves the field of view of photoelectric switch 1A, the control system causes the first clamping mechanism 21 to release the second group of irregularly shaped bottles 5 so that the second group of irregularly shaped bottles 5 can continue to move forward. In this way, the first group of irregularly shaped bottles 5 and the second group of irregularly shaped bottles 5 are separated by a distance so that they can smoothly enter the bottle feeding wheel 4. After passing through the action of the bottle feeding wheel 4, they enter the downstream detection area for individual detection.

[0039] Preferably, such as Figure 3-4 As shown, when the irregularly shaped bottle groups 5 conveyed by the conveying device 1 are close to each other, in order to avoid bottle blockage on the conveying device 1 and to ensure that the irregularly shaped bottle groups 5 enter the bottle feeding wheel 4 in a single group, in the preferred embodiment of this utility model, the bottle clamping device 2 further includes multiple sets of second clamping mechanisms 22 arranged sequentially and at intervals along the conveying direction of the conveyor belt 11. The second clamping mechanisms 22 are located upstream of the first clamping mechanism 21, and are used to clamp or release the passing irregularly shaped bottle groups 5 under the action of the control device. The photoelectric detection component also includes multiple sets of second photoelectric switches corresponding to each second clamping mechanism 22. Each set of second photoelectric switches is located downstream of the corresponding second clamping mechanism 22, and is used to detect whether an irregularly shaped bottle group 5 has passed through the set position. In this embodiment, both the bottle clamping device 2 and the photoelectric detection component have simple structures and simple operation processes.

[0040] During operation, taking the setup of a second clamping mechanism 22 and a second photoelectric switch as an example, and assuming that the second photoelectric switch is photoelectric switch 3A; when photoelectric switch 3A detects that there is no irregularly shaped bottle group 5, the control device causes the second clamping mechanism 22 to release, allowing the third irregularly shaped bottle group 5 to pass through. When the third irregularly shaped bottle group 5 enters the field of view of photoelectric switch 3A and is detected, the control device causes the second clamping mechanism 22 to clamp the incoming fourth irregularly shaped bottle group 5; when the third irregularly shaped bottle group 5 continues to move forward and leaves the field of view of photoelectric switch 3A, when photoelectric switch 3A detects that there is no irregularly shaped bottle group 5, it instructs the second clamping mechanism 22 to release, allowing the fourth irregularly shaped bottle group 5 to pass through. The second clamping mechanism 22 is clamped and released by photoelectric switch 3A, thereby controlling the total number of irregular bottle groups 5 between the second clamping mechanism 22 and the first clamping mechanism 21, so that the tightly packed bottle rows become loosely arranged irregular bottle groups 5; when the loose irregular bottle groups 5 pass through the first clamping mechanism 21, they are separated into irregular bottle groups 5 with equal distance between them by photoelectric switch 3A and photoelectric switch 7A, so that they can smoothly enter the bottle feeding wheel 4 to the detection area for detection.

[0041] Optionally, such as Figure 5-6 As shown, the first clamping mechanism 21 and the second clamping mechanism 22 have the same structure, both including a servo motor 201 mounted on the frame, a transmission screw 202 connected to the output end of the servo motor 201, and two clamping blocks 203 that cooperate to clamp the passing irregularly shaped bottle group 5. The outer circumferences at both ends of the transmission screw 202 are respectively machined with external threads in opposite directions; the two clamping blocks 203 are respectively threaded onto the outer circumferences at both ends of the transmission screw 202. During operation, the servo motor 201 rotates, causing the two clamping blocks 203 to move closer together to clamp the irregularly shaped bottle group 5, or to move away from each other to release the clamped irregularly shaped bottle group 5; the operation is simple.

[0042] Optionally, the irregularly shaped bottle feeding device also includes a mounting plate disposed on the frame and located above the conveyor belt 11; such as Figure 3-4 As shown, two sets of first photoelectric switches and multiple sets of second photoelectric switches are arranged sequentially and at intervals along the extension direction of the mounting plate, such as photoelectric switches 1A, 2A, and 3A, to detect irregularly shaped bottle groups 5 whose height is lower than the limit fence 12, such as those attached to the mounting plate. Figure 1 The irregularly shaped bottle group 5 shown is inspected; alternatively, two sets of first photoelectric switches and multiple sets of second photoelectric switches are arranged sequentially at intervals along the outer side of the limiting fence 12, and through holes are provided on the limiting fence 12 corresponding to the first and second photoelectric switches, so as to inspect the irregularly shaped bottle group 5 with a higher height, as shown in the attached figure. Figure 2 The irregularly shaped bottle group 5 shown includes photoelectric switches 1B, 2B, and 3B.

[0043] Optionally, such as Figure 4As shown, the bottle feeding wheel 4 includes a rotating wheel body 41 and a bottle feeding grid 42 surrounding the outer side of the wheel body 41. The outer periphery of the wheel body 41 is machined with recessed grooves arranged sequentially along the circumference. The grooves 410 are used to feed a group of irregularly shaped bottles 5 from the outlet of the conveyor belt 11 into the wheel body 41 during rotation. At the same time, the bottle feeding grid 42 helps to confine the irregularly shaped bottles 5 in the grooves 410 so that they can move forward with the wheel body 41.

[0044] Preferably, the shape of the groove 410 is adapted to the shape of the irregular bottle group 5 so that the irregular bottle group 5 can be stably conveyed forward by the dial wheel body 41; the dial wheel body 41 is detachably fixed to the frame so that the dial wheel body 41 with different grooves 410 can be replaced to correspond to irregular bottle groups 5 with different shapes.

[0045] An inspection device is provided, which has a bottle feeding device for irregularly shaped bottles as described above. The inspection device of this utility model allows the irregularly shaped bottle group 5 to enter the bottle feeding wheel 4 separately, so as to separate and transport the irregularly shaped bottle group 5 for subsequent independent inspection. This solves the technical problem in the prior art that it is impossible to independently inspect non-circular irregularly shaped bottle groups 5. Moreover, the entire bottle feeding device has a simple structure, simple operating principle, and low manufacturing cost.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
