Description

Technical Field

[0001] The utility model belongs to the field of detection devices, in particular to a counting device and a detection mechanism using the device. Background Art

[0002] In the production of large-volume injections, plastic bottles / glass bottles are widely used to contain injections. A production line is equipped with multiple channels for conveying plastic bottles / glass bottles. When the number of bottled products in each channel reaches a certain number, the system will switch the conveying channel to improve production efficiency.

[0003] In the prior art, the lever principle is usually used in combination with a photoelectric switch for counting. The photoelectric switch is the abbreviation of a photoelectric proximity switch. The photoelectric switch converts the input current into a light signal on the transmitter and then emits it. The receiver then detects the target object based on the intensity or presence of the received light. The object being detected blocks or reflects the light beam, and the synchronous circuit connects the circuit to detect the presence of the object. The output path of the light signal is fixed, and the lever principle is used for measurement on the output path. However, due to the indefinite size and shape of the detected object, the detection piece and the paddle disclosed in the CN215932667U patent are arranged into a linear counting mechanism. After the detection object is replaced, the distance between the paddle and the photoelectric switch needs to be determined to ensure that the detection piece does not block the light signal output path of the photoelectric switch after the paddle is rotated. The adjustment is complicated and it is easy to miss the detection. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a counting device which can ensure that the pick is always on the output path of the light signal when the detection object is replaced and will not cause measurement errors.

[0005] The technical solution adopted by the utility model to solve its technical problem is: the counting device includes a detection piece, a paddle, a detection switch and a limit structure, the paddle is arranged vertically, the detection piece is horizontally connected to the upper part of the paddle, the detection piece is arranged on one side of the detection switch, the limit structure is arranged on the lower side of the detection piece and is in contact with the lower side of the detection piece, and the paddle is driven by the detection object and drives the detection piece to swing together.

[0006] Preferably, the paddle and the detection piece are arranged perpendicular to each other.

[0007] Preferably, the paddle is bent at a certain angle along the moving direction of the detection object.

[0008] Preferably, a plurality of weight-reducing holes are provided on the detection piece and the paddle.

[0009] Preferably, the limiting structure is a paddle limiting shaft.

[0010] Preferably, the detection piece and the paddle are fixedly connected via a connecting sleeve.

[0011] A detection mechanism includes a paddle fixing shaft, a detection switch fixing frame, a bracket and a baffle. A conveying channel is formed between two adjacent baffles. The paddle fixing shaft and the detection switch fixing frame are arranged on the bracket in parallel. The connection between the detection piece and the paddle is rotatably set on the paddle fixing shaft. The paddle is set above the conveying channel, and the detection switch is set on the detection switch fixing frame.

[0012] Preferably, the bracket is provided with a height adjustment structure for adjusting the paddle fixing shaft, the detection switch fixing frame and the limit structure.

[0013] Preferably, the height adjustment structure is an adjustment slot vertically arranged on the bracket, and the paddle fixing shaft, the detection switch fixing frame and the limit structure are arranged in the adjustment slot.

[0014] Compared with the existing technology, the beneficial effects of this technical solution are:

[0015] The present invention limits the detection piece by providing a limiting structure on the lower side of the detection piece. The detection switch is provided on one side of the detection piece. When the paddle is driven by the detection object and rotates along the axis of the connecting sleeve, the detection piece does not block the light signal of the detection switch. When the paddle returns to its original position, the detection piece follows the paddle and rotates to the limiting structure, blocking the detection piece from continuing to rotate due to inertia. This prevents excessive inertial rotation from blocking the light signal of the detection switch, causing measurement errors by the detection switch. Furthermore, regardless of the size of the detection object, the detection piece always maintains its initial position at a position that blocks the detection switch due to the limiting action of the paddle limiting shaft, and no adjustment is required.

DETAILED DESCRIPTION

[0021] Figures 1 to 4This is the best embodiment of the present invention, Figures 1 to 4 The utility model is further described.

[0022] Reference Figure 1 The counting device includes a detection switch 4, a detection piece 2, a paddle 3, a connecting sleeve 1, and a paddle limiting shaft 5. The detection piece 2 and the paddle 3 are connected by the connecting sleeve 1. The detection switch 4 is disposed on one side of the detection piece 2. In this embodiment, the limiting structure is the paddle limiting shaft 5, which is disposed on the underside of the detection piece 2 and abuts against the underside of the detection piece 2. Driven by the detection object 6, the paddle 2 rotates along the axis of the connecting sleeve 1. The detection piece 2 blocks or does not block the electrical signal of the detection switch 4, thereby counting the number of detection objects 6.

[0023] The paddle 3 and the detection piece 2 are two rectangular paddles arranged perpendicular to each other, with the paddle 3 arranged vertically and the detection piece 2 arranged horizontally. The lower end of the paddle 3 is provided with an angle where it contacts the detection object 6, so that the detection object 6 can easily leave the paddle 3 after it drives the paddle 3.

[0024] When the detection object 6 drives the paddle 3 to deflect a certain angle in the direction of movement, the detection piece 2 moves away from the detection switch 4 until the light signal is unblocked. After the detection object 6 passes the paddle 3, the paddle 3 rotates to the vertical direction due to its own gravity, and the detection piece 2 follows and rotates to the paddle limit axis 5. The detection piece 2 blocks the light signal of the detection switch 4, thereby measuring once.

[0025] The detection piece 2 and the paddle 3 are provided with a plurality of weight-reducing holes to reduce their own weight.

[0026] The detection mechanism of the counting device is used to measure whether the detection objects 6 of each production line on the multi-line transport production line have reached a preset number. The control system will switch to another conveying channel to improve the efficiency of transport and filling.

[0027] The detection mechanism includes a paddle fixing shaft 8, a detection switch fixing frame 9, a detection switch mounting bracket 10, a bracket 7 and a baffle 12. The conveyor frame 13 of the production line is divided into multiple columns of conveying channels by the baffle 12. The two brackets 7 are symmetrically fixed on both sides of the conveyor frame 13. The paddle fixing shaft 8 and the detection switch fixing frame 9 are arranged parallel to the upper side of the bracket 7 and the upper side of the baffle 12. Multiple connecting sleeves 1 are arranged on the paddle fixing shaft 8 and correspond to the conveying channels divided by the baffle 12 respectively. The detection switch 4 is arranged on the detection switch fixing frame 9 and has the same height as the detection piece 2.

[0028] The paddle fixing shaft 8 is set on the side close to the detection object 6, and the detection switch fixing frame 9 is set on the side away from the detection object 6. The two sides of the connecting sleeve 1 are fixed to the paddle fixing shaft 8 through the shaft with a retaining ring 11. The detection piece 2 is horizontally perpendicular to the paddle fixing shaft 8 and is set between the paddle fixing shaft 8 and the detection switch fixing frame 9. The wide side of the detection piece 2 blocks the light signal of the detection switch 4. The paddle 3 is set vertically perpendicular to the paddle fixing shaft 8, corresponding to each column of conveying channels.

[0029] The detection switch 4 is fixed to the detection switch mounting bracket 9 via the detection switch mounting bracket 10 and is also located between the detection switch mounting bracket 9 and the paddle fixing shaft 8. The detection switch mounting bracket 10 has two layers of parallel fixing plates, fixed by a vertical plate between the two fixing plates, with a certain distance between the two fixing plates. One fixing plate is fixed to the detection switch mounting bracket 9, and the other fixes the detection switch 4. In other words, the detection switch 4 extends horizontally a distance and horizontally overlaps one side of the detection plate 2. This allows the detection plate 2 to block the light signal of the detection switch 4 in its initial position.

[0030] Multiple adjustment slots 14 are vertically defined along the upper side of the bracket 7. In this embodiment, three vertical bar-shaped adjustment slots 14 are provided. The paddle fixing shaft 8, the detection switch fixing bracket 9, and the paddle limiting shaft 5 are each mounted within these adjustment slots 14 via nuts. The heights of the paddle fixing shaft 8, the detection switch fixing bracket 9, and the paddle limiting shaft 5 are adapted to the height of the detection object 6, enabling measurement of detection objects 6 of varying sizes.

[0031] Working process:

[0032] The control system of the conveyor line sets the number of detection objects 6 per column. When this number is reached and the system determines that the conveyor channel is full of bottles, the detection objects 6 drive the paddle 3 to deflect a certain angle along the conveying direction. The detection plate 2 deflects upward by the same angle along the paddle fixed axis 8. At this time, the detection plate 2 cannot block the light signal of the detection switch 4. When the detection object 6 continues to move forward and passes through the paddle 3, the paddle 3 rotates back to the vertical position due to its own gravity. At this time, the detection plate 2 also rotates to the paddle limit axis 5, blocking the light signal of the detection switch 4, thus measuring once. After repeated measurement, when the bottle is full, the control system controls the conveyor to switch the conveying channel, improving the efficiency of conveying and filling.

[0033] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
