Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a device for detecting crooked bottles. Background Art

[0002] When using a filling machine for production and processing, if the bottle body is tilted, it is easy to cause damage to the star wheel guard plate, filling valve, bottle support cylinder, etc., resulting in serious collision accidents. If manual real-time monitoring is used to check whether the bottle body is tilted, it is very labor-intensive. Utility Model Content

[0003] The purpose of the utility model is to provide a device for detecting crooked bottles, so as to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems is: a bottle crooked detection device for detecting crooked bottles in bottle body processing equipment, the detection device comprising: a bracket, comprising a connected cross bar and a longitudinal bar; a detection frame, rotatably mounted on the cross bar, the detection frame forming a detection channel for the bottle body to pass through; a sensor, communicatively connected to the processing equipment, the sensor being configured to generate a detection signal and send it to the processing equipment when the detection frame rotates, thereby stopping the processing equipment.

[0005] This technical solution has at least the following beneficial effects: the bracket is installed on the bottle conveying equipment of the processing equipment so that the detection channel of the detection frame corresponds to the bottle conveying path. When a bottle is crooked, the crooked bottle will hit the detection frame and cause the detection frame to swing. After the sensor detects the swing of the detection frame, it can generate a detection signal and send it to the processing equipment. After the processing equipment receives the detection signal, it indicates that a crooked bottle has occurred, so it needs to be shut down. The worker can remove the crooked bottle and reset it and restart it. This can prevent the crooked bottle from causing serious collision accidents to processing equipment such as filling machines, and reduce the losses caused by damage to the star wheel guard plate, filling valve, bottle supporting cylinder, etc.

[0006] As a further improvement to the above technical solution, the detection frame is mounted with a first screw, the crossbar is provided with a slide groove for the first screw to slide, and the first screw is threadedly mounted with a first nut and a second nut, which clamp the crossbar. By rotating the first and second nuts, the height of the detection frame can be adjusted, thereby improving adaptability to the detection of bottles of different sizes or transport heights. After loosening the first and second nuts, the first screw can slide within the slide groove to adjust the position of the detection frame relative to the bracket, that is, the installation position of the bracket can be adjusted to adapt to bottle transport scenarios of different processing equipment, further improving adaptability.

[0007] As a further improvement to the above technical solution, the inspection frame includes a top plate and two side plates slidably mounted on either side of the top plate. The top plate is equipped with fixings for securing the side plates. Adjusting the distance between the two side plates accommodates bottle inspections of varying widths and also adjusts the error in detecting bottle skew.

[0008] As a further improvement to the above technical solution, the fixing member includes a second screw disposed on the side panel and a third nut threadedly connected to the second screw. The top panel defines an adjustment slot for the second screw to pass through, and the side panel and the third nut are configured to clamp the top panel. Loosening the third nut allows the side panel to be moved, allowing the second screw to slide within the adjustment slot to adjust the position of the side panel. Tightening the third nut secures the adjusted side panel.

[0009] As a further improvement to the above technical solution, the fixing member includes a third screw rotatably mounted on the top plate, an adjustment block being threadedly mounted on the third screw, and connecting rods rotatably mounted on both sides of the adjustment block, with the ends of the connecting rods on both sides, distal from the adjustment block, being rotatably connected to the corresponding side plates. Rotating the third screw drives the adjustment block to move, and the transmission action of the connecting rods drives the side plates on both sides toward or away from each other, thereby facilitating simultaneous adjustment of the positions of the two side plates, and improving the overall stability of the detection frame after adjustment.

[0010] As a further improvement to the above technical solution, the top plate is provided with a dovetail groove, and the side plates are provided with dovetail blocks slidably arranged in the dovetail groove. The dovetail groove is used to limit the sliding of the side plates, thereby improving the stability of the movement of the side plates.

[0011] As a further improvement of the above technical solution, the sensor is a proximity switch, which is mounted on the crossbar with its sensing surface facing the detection frame. Proximity switch technology is mature and can ensure detection sensitivity and reliability.

[0012] As a further improvement to the above technical solution, the longitudinal rod includes a latch, a first rod, and a second rod slidably mounted on the first rod. The first rod has a first positioning hole, and the second rod has multiple second positioning holes arranged side by side along its length. The latch is inserted into the first positioning hole and one of the second positioning holes. After releasing the latch, the height of the detection frame can be adjusted over a wide range by sliding the first rod. The height of the detection frame can be adjusted by aligning the first positioning hole of the first rod with the second positioning hole at a nearly appropriate height and then inserting the latch.

[0013] As a further improvement to the above technical solution, an inclined rod is connected between the top of the longitudinal rod and the transverse rod, and the top end of the inclined rod is tilted away from the detection frame. The inclined rod can balance the weight of the detection frame and improve the stability of the longitudinal rod.

[0014] As a further improvement of the above technical solution, a reinforcing rib is connected between the longitudinal rod and the transverse rod, and a triangular structure is formed between the reinforcing rib, the longitudinal rod and the transverse rod, thereby improving the support for the transverse rod.

The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0024] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0025] Example 1:

[0026] Reference Figure 1-2 The crooked bottle detection device includes a bracket 100, which includes a longitudinal rod 110 and a transverse rod 120, so that the bracket 100 is in the shape of a "7". A support plate is installed at the bottom of the longitudinal rod 110, and the support plate has holes for bolt installation, so that the longitudinal rod 110 can be firmly installed in the desired position.

[0027] The inspection frame 200 includes a top plate 220 and two side plates 230, one located on either side of the bottom of the top plate 220. A fixing member 400 is mounted on the top plate 220, comprising a second screw 411 and a third nut 412. The second screw 411 is vertically mounted at one end of the top of the side plate 230, while a guide post 414 is vertically mounted at the other end of the top of the side plate 230. Adjustment slots 413 are defined on both sides of the top plate 220, with their lengths parallel to the lengths of the slide slots 121. The guide post 414 on one side plate 230 slides in the first adjustment slot 413, while the second screw 411 on that side slides in the second adjustment slot 413. The guide post 414 on the other side plate 230 slides in the second adjustment slot 413, while the second screw 411 on that side slides in the first adjustment slot 413. This results in the guide posts 414 and second screws 411 in the side panels 230 being arranged in opposite positions. The guide posts 414 and second screws 411 can slide in their corresponding adjustment slots 413, allowing the relative positions of the side panels 230 to be adjusted. After passing through the corresponding adjustment slots 413, the second screws 411 in the side panels 230 are threadedly connected to the third nuts 412. Tightening the third nuts 412 restricts the position of the side panels 230, maintaining their relative position. It should be noted that the space between the two side panels 230 forms the inspection channel 210, through which the transport line for bottles to be inspected passes.

[0028] Axle seats 240 are fixedly mounted on both sides of the top of the top plate 220. A rotating shaft 250 is disposed between the two shaft seats 240. Both ends of the rotating shaft 250 are rotatably mounted in the corresponding shaft seats 240 via bearings. A first screw 300 is vertically mounted in the middle of the rotating shaft 250. The first screw 300 is sequentially threadedly connected to a first nut 310 and a second nut 320 in a direction away from the rotating shaft 250. A sliding groove 121 is defined at the top of the crossbar 120, running parallel to its length. When the inspection frame 200 is installed as a whole on the cross bar 120, the first nut 310 is first screwed into the first screw rod 300, and the first nut 310 is at the bottom position. Then, the first screw 300 is passed through the slide groove 121 from bottom to top and then screwed into the second nut 320. The position of the second nut 320 on the first screw 300 is adjusted according to the height requirement of the inspection frame 200. The overall lateral position of the inspection frame 200 is adjusted by sliding the first screw 300 in the slide groove 121 so that the transport line path of the bottle to be inspected can be located in the middle of the two side plates 230 in the inspection frame 200. Finally, the first nut 310 is tightened upward until it contacts the bottom of the cross bar 120, so that the first nut 310 and the second nut 320 clamp the cross bar 120, and the inspection frame 200 is maintained at a suitable height and lateral position.

[0029] A sensor connected to the processing equipment is mounted on crossbar 120. When inspection frame 200 rotates, the sensor generates a detection signal and sends it to the processing equipment. This detection signal is then fed into the equipment's PLC control program, triggering an alarm and shutdown on the HMI. Upon receiving the detection signal, the processing equipment determines that a skewed bottle has struck the side panels 230 of inspection frame 200 in the bottle transport line. This force causes inspection frame 200 to rotate, triggering the sensor to generate a detection signal. Because a skewed bottle's support ring or thread position can be damaged to varying degrees, rendering the bottle useless, the processing equipment is shut down upon receiving the detection signal, allowing workers to remove any unacceptable bottles and then reset and restart the machine to prevent the unacceptable bottles from affecting subsequent processing and damaging the equipment.

[0030] In this embodiment, the sensor may be a proximity switch 500. The proximity switch 500 is a position switch that can be operated without direct mechanical contact with moving parts. When an object approaches the sensing surface of the switch to the operating distance, the proximity switch 500 is activated without mechanical contact or the application of any pressure, generating a signal. A support bar 510 is mounted horizontally on the rotating shaft 250, and the length of the support bar 510 is perpendicular to the length of the rotating shaft 250. The proximity switch 500 is mounted on the end of the support bar 510 away from the rotating shaft 250, and the sensing surface of the proximity switch 500 faces the top plate 220. Regardless of which side panel 230 is impacted, the top plate 220 will swing closer to the sensing surface of the proximity switch 500, causing the proximity switch 500 to generate a detection signal and transmit it to the processing equipment.

[0031] In other embodiments, the sensor can also be an angle sensor, which is installed on the rotating shaft 250, and the sensing end of the angle sensor is used to detect the rotation angle of the shaft seat 240. When the shaft seat 240 rotates relative to the rotating shaft 250, the angle sensor generates a detection signal and sends it to the processing equipment.

[0032] Example 2:

[0033] Reference Figure 3-4This embodiment differs from the first embodiment in the specific structures of the detection frame 200 and the bracket 100. In this embodiment, the fixing member 400 includes a third screw 421, which is rotatably mounted at the bottom of the top plate 220. The length of the third screw 421 is perpendicular to the length of the rotating shaft 250. A handle is mounted on one end of the third screw 421 to facilitate rotation of the third screw 421. The third screw 421 is threadedly connected to an adjustment block 422. Connecting rods 423 are rotatably mounted on both sides of the adjustment block 422. The ends of the connecting rods 423, distal from the adjustment block 422, are rotatably connected to the corresponding side plate 230. When the operating handle rotates the third screw 421, the adjustment block 422 slides, pulling or pushing the connecting rods 423 on both sides, moving the side plates 230 closer or further apart. This facilitates adjustment of the relative position of the side plates 230.

[0034] A dovetail groove 431 is provided at the bottom of the top plate 220, the length direction of which is perpendicular to the length direction of the third screw 421. The two ends of the dovetail groove 431 pass through both sides of the top plate 220. A dovetail block 432 is installed on the top of the side plate 230. The dovetail block 432 can be slidably embedded in the dovetail groove 431, so that the side plate 230 can slide stably relative to the top plate 220.

[0035] The longitudinal rod 110 includes a vertically disposed first rod 112, a vertically disposed second rod 114, and a latch 111. The bottom of the second rod 114 is fixedly connected to the support plate. The second rod 114 is a hollow tube, allowing the bottom end of the first rod 112 to be inserted and slidable within the interior of the second rod 114. A first positioning hole is defined at the bottom of the first rod 112, and multiple second positioning holes 115 are defined in parallel along the vertical direction of the second rod 114. After the first rod 112 is inserted into the second rod 114 and adjusted to a nearly appropriate position, the first positioning hole is aligned with the closest second positioning hole 115. The latch 111 is then inserted into the first and second positioning holes 115, completing the relative fixation between the first and second rods 112, 114. This allows for a wide range of adjustment of the installation height of the detection frame 200. The height of the detection frame 200 can then be adjusted within a smaller range using the first screw 300, the first nut 310, and the second nut 320 to meet varying height requirements for the detection frame 200.

[0036] In order to improve the supporting stability of the bracket 100, an inclined rod 600 is installed on the top of the longitudinal rod 110. The top of the inclined rod 600 is connected to the cross bar 120. The top of the inclined rod 600 is tilted away from the detection frame 200. A reinforcing rib 700 is also installed between the longitudinal rod 110 and the cross bar 120. An inverted isosceles triangle structure is formed between the reinforcing rib 700, the inclined rod 600 and the cross bar 120, thereby improving the supporting stability of the bracket 100 for the detection frame 200.

[0037] In other embodiments, if the tilt rod 600 is not provided but the reinforcing rib 700 is provided, an equilateral right-angled triangle structure is formed between the reinforcing rib 700, the longitudinal rod 110 and the transverse rod 120, which can also improve the support stability of the bracket 100 for the detection frame 200.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
