Description

Technical Field

[0001] The utility model relates to the technical field of bottled product conveying lines, in particular to a bottle-falling rejection structure and a conveying device on a production line. Background Art

[0002] After some bottled materials are processed on the production line, they need to be transported to the next process flow through a conveying structure, such as some medicine packaging bottles, beverage packaging bottles, food packaging bottles, etc. These bottled materials usually tip over on the conveyor belt during the transportation process. As the conveying mechanism transports them, if the tipped bottles are not straightened or removed in time, it is likely to cause the next process of the production line to get stuck. If the bottles are stuck, the machine needs to be stopped and they need to be straightened or removed manually, which seriously affects production efficiency.

[0003] Patent CN201520579056.7 discloses a bottle conveying device, including a bottle conveying mesh belt and guardrails arranged on both sides of the bottle conveying mesh belt, a transition turntable is arranged at the turning point of the bottle conveying mesh belt to drive the bottle to turn, and the guardrail adjacent to the transition turntable is provided with a curved guide wall, and the inner side of the curved guide wall is provided with a falling bottle collection port, and the opening direction of the falling bottle collection port is opposite to the bottle conveying direction of the bottle conveying mesh belt. When the falling bottle reaches the turning point under the drive of the bottle conveying mesh belt, the falling bottle directly enters the falling bottle collection port, and no longer moves forward with the mesh belt.

[0004] Although the inverted bottle rejection structure installed on some current transport devices can reject some inverted bottles, it still has some functional defects. For example, in the above-mentioned patent, only the inverted bottles that are aligned with the inverted bottle collection port can be rejected and collected, while the inverted bottles that are not aligned with the inverted bottle collection port are difficult to collect. In addition, the current inverted bottle rejection device usually does not have a structure for detecting inverted bottles, making it difficult to achieve the effect of automatic rejection. Therefore, the inverted bottle collection structure on the current conveying device still has certain technical defects. Utility Model Content

[0005] Based on the problem pointed out in the background technology that the inverted bottle rejection device on the existing production line has no structure for detecting inverted bottles and is difficult to achieve automatic rejection, the purpose of the present application is to propose a inverted bottle rejection structure and a conveying device on the production line. The inverted bottle rejection structure can accurately detect whether there are inverted bottles on the production line by setting a inverted bottle detection structure. At the same time, the upper photoelectric detector on the detection structure is set to a structure that can move up and down, so that the detection structure can detect bottles of different heights, so that the inverted bottle rejection structure has a wider range of application and stronger functionality, and can achieve the effect of automatically rejecting inverted bottles.

[0006] The utility model is realized by the following technical solutions:

[0007] In the first aspect, the present application provides a structure for rejecting a fallen bottle on a production line, comprising support frames installed on both sides of a conveyor belt, wherein the support frame on one side is connected to a bottle receiving structure, and the support frame on the other side is connected to a bottle pushing structure; the support frame on either side is connected to a fallen bottle detection structure; the fallen bottle detection structure comprises a vertical support plate connected to the support frame, the lower end of the vertical support plate is connected to a lower photoelectric detector, and the upper end of the vertical support plate is connected to an upper photoelectric detector via a sliding structure; the lower photoelectric detector, the upper photoelectric detector, and the bottle pushing structure are all communicatively connected to a PLC controller.

[0009] Furthermore, the locking structure includes bolt holes arranged on the slider and the vertical support plate, and a plurality of bolt holes are arranged at intervals on the vertical support plate. When the bolt hole on the slider is aligned with any bolt hole on the vertical support plate, a locking bolt is inserted into the bolt hole and tightened to fix the slider on the vertical support plate.

[0010] Furthermore, the bottle pushing structure includes any one of an electric telescopic rod, a gas cylinder, and a hydraulic cylinder connected to the support frame.

[0011] If an electric telescopic rod is used, a push plate is connected to the telescopic end of the electric telescopic rod, and a buffer pad for protecting the inverted bottle can also be connected to the push plate.

[0012] If a pneumatic cylinder or a hydraulic cylinder is used, a push plate is connected to the movable rod of the pneumatic cylinder or the hydraulic cylinder, and a buffer pad for protecting the inverted bottle can also be connected to the push plate.

[0013] Furthermore, the bottle receiving structure includes a placement plate connected to the support frame, and a bottle receiving frame is placed on the placement plate.

[0015] Furthermore, a gravity sensor is connected to the placement plate, and an alarm is connected to the support frame for communication with the gravity sensor.

[0016] Furthermore, the support frame is also connected to a bottle tilting correction structure.

[0018] In a second aspect, the present application proposes a conveying device, including a production line inverted bottle rejection structure of any one of the above-mentioned technical solutions.

[0019] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0020] (1) The inverted bottle rejection structure of the present application can accurately detect whether there are inverted bottles on the production line by setting up an inverted bottle detection structure. At the same time, the upper photoelectric detector on the detection structure is set to a structure that can move up and down, so that the detection structure can detect bottles of different heights, making the inverted bottle rejection structure more applicable and more functional, and can achieve the effect of automatically rejecting inverted bottles;

[0021] (2) The present application connects a gravity sensor to the bottle receiving frame placement plate, and can detect the weight of the received bottle through the gravity sensor. By first predicting the weighing method, the gravity value generated when the bottle receiving frame is full of inverted bottles is determined, and the gravity value is set on the gravity sensor.

[0022] (3) The present application connects a bottle-inverting correction structure to the support frame.

Not only can the push plate smoothly push the inverted bottle into the bottle receiving frame, but also the inverted bottle can be placed more neatly when entering the bottle receiving frame, thereby reducing the work of subsequent adjustments by the staff.

[0035] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, a connection or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Example 1

[0037] like Figures 1 to 4 As shown, this embodiment provides a conveying device, including a bottle-falling rejection structure and a conveyor belt 01, wherein the bottle-falling rejection structure is installed on support frames 02 on both sides of the conveyor belt 01, wherein the support frame 02 on one side is connected with a bottle receiving structure, and the support frame 02 on the other side is connected with a bottle pushing structure 03; the support frame 02 on either side is connected with a bottle-falling detection structure; the bottle-falling detection structure includes a vertical support plate 07 connected to the support frame 02, the lower end of the vertical support plate 07 is connected with a lower photoelectric detector 12, and the upper end of the vertical support plate 07 is connected with an upper photoelectric detector 11 through a sliding structure; the lower photoelectric detector 12, the upper photoelectric detector 11, and the bottle pushing structure 03 are all communicatively connected to a PLC controller.

[0038] Specifically, the sliding structure in this embodiment includes a slide rail 08 provided on the vertical support plate 07, a slider 09 is connected to the slide rail 08, and an upper photodetector 11 is connected to the slider 09; the slider 09 is connected to the vertical support plate 07 via a locking structure. The locking structure includes bolt holes 13 provided on the slider 09 and the vertical support plate 07, and a plurality of bolt holes 13 are provided at intervals on the vertical support plate 07. When the bolt holes 13 on the slider 09 are aligned with any bolt holes 13 on the vertical support plate 07, a locking bolt 10 is inserted into the bolt hole 13 and tightened to fix the slider 09 on the vertical support plate 07.

[0039] Specifically, the bottle pushing structure 03 in this embodiment is an electric telescopic rod, a push plate 04 is connected to the telescopic end of the electric telescopic rod, and a buffer pad is connected to the push plate 04 for protecting the inverted bottle and reducing the collision between the push plate 04 and the inverted bottle.

[0040] Specifically, the bottle receiving structure in this embodiment includes a placement plate 05 connected to the support frame 02, and a bottle receiving frame 14 is placed on the placement plate 05. A fixing structure for fixing the bottle receiving frame 14 is connected to the support frame 02; the fixing structure includes an L-shaped fixing block 06 slidably connected to the support frame 02; a slide groove 15 is provided on the support frame 02, and a compression spring 16 is connected in the slide groove 15, one end of the compression spring 16 is fixed to the top of the slide groove 15, and the other end is connected to the L-shaped fixing block 06.

[0041] Before using the conveying device to transport the bottle, the staff adjusts the height of the upper photoelectric detector 11 according to the actual height of the bottle, so that the upper photoelectric sensor can just detect the top of the bottle. When both the upper photoelectric sensor and the lower photoelectric sensor detect the bottle, it means that the detected bottle has not fallen. When the upper photoelectric sensor does not detect the bottle, and only the lower photoelectric sensor detects the bottle, it means that the bottle has fallen. At this time, the lower photoelectric sensor transmits a signal to the electric telescopic rod. Through the extension of the electric telescopic rod, the fallen bottle can be pushed into the bottle receiving frame 14 by the push plate 04 connected to the electric telescopic rod, thereby completing the collection of the fallen bottle.

[0042] The upside-down bottle rejection structure installed on the conveying device can accurately detect whether there are upside-down bottles on the production line by setting up an upside-down bottle detection structure. At the same time, the upper photoelectric detector 11 on the detection structure is set to a structure that can move up and down, so that the detection structure can detect bottles at different heights, making the upside-down bottle rejection structure have a wider range of applications and stronger functionality, and can achieve the effect of automatically rejecting upside-down bottles.

[0043] Example 2

[0044] like Figure 5 As shown, based on Example 1, this example provides a conveying device. The difference from Example 1 is that the conveying device in this example is connected to a gravity sensor 17 on the placement plate 05, and an alarm is connected to the support frame 02 for communication with the gravity sensor 17.

[0045] Compared with Example 1, the conveying device of this embodiment has the advantages that: by connecting the gravity sensor 17 to the placement plate 05 of the bottle receiving frame 14, the weight of the received bottle body can be detected by the gravity sensor 17, and the gravity value generated when the bottle receiving frame 14 is full of inverted bottles is determined by first predicting the weighing method, and the gravity value is set on the gravity sensor 17. When the gravity sensor 17 detects the gravity value, it transmits a signal to the alarm, and the alarm is used to inform the staff that the bottle receiving frame 14 is full of bottles to avoid overflow of bottles.

[0046] Example 3

[0047] like Figure 6 As shown, based on Example 2, this embodiment provides a conveying device, which is different from Example 2 in that a bottle tilting correction structure is also connected to the support frame 02 in this embodiment; the bottle tilting correction structure includes an arc plate 18 connected to the support frame 02, and the arc plate 18 is connected between the bottle pushing structure 03 and the bottle tilting detection structure. It can also be connected to the front end of the bottle tilting detection structure.

[0048] Compared with Example 2, the conveying device of this embodiment has the advantage that: by connecting the inverted bottle correction structure to the support frame 02, when the inverted direction of the bottle body is not parallel to the conveying direction of the conveyor belt, the inverted bottle can be adjusted to be parallel to the conveying direction of the conveyor belt through the arc plate 18, and then made parallel to the push plate 04 of the bottle pushing structure 03, not only the push plate 04 can smoothly push the inverted bottle into the bottle receiving frame 14, but also the inverted bottle can be placed more neatly when entering the bottle receiving frame 14, reducing the work of subsequent adjustments by the staff.
