[0002] With the progress of the times, various technologies have made rapid progress, the competition in the pull-open lid industry has become increasingly fierce, and the production speed of the production line has become faster and faster. With the increase in production speed and output, the problem of counting the number of pull-open lids has become more and more troubling for various companies. In the past, the counting of pull-open lids was mostly done by measuring the total mass of the pull-open lids divided by the mass of a single pull-open lid. With the density problem of different batches of iron sheets, this weighing and counting method has a large error.

[0003] In the related art, physical technical methods are used to count the round covers in the stack. For example, Chinese utility model patent CN207817774U discloses a physical counting device for easy-open lids, which uses a probe to constantly abut against the round covers in the stack, and as the round covers move or the probe moves through the gaps between the round covers in the stack, a lever is driven to trigger a counting sensor, thereby calculating the number of round covers. However, the device is easy to scratch the round covers and is easy to get stuck on some round covers without chamfered edges, so it has poor versatility. Utility Model Content

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference below Figure 1 , the implementation of the counting device proposed in the embodiment of the utility model is described in detail.

[0024] The counting device according to the embodiment of the utility model comprises: a conveying channel (not shown) and a counting component 1.

[0025] Specifically, the conveying channel is suitable for conveying a stack of round caps formed by a plurality of round caps 2 arranged in an array; the counting component 1 has a gear 11 and an encoder 12; the gear 11 is rotatably arranged, and a plurality of teeth 111 are evenly distributed on the outer circumference of the gear 11; the tooth pitch between two adjacent teeth 111 is consistent with the thickness of a single round cap 2; when the stack of round caps is continuously conveyed, the plurality of round caps 2 abut against the plurality of teeth 111 one by one to rotate the gear 11; the encoder 12 is connected to the gear 11 to detect the rotation angle of the gear 11.

[0026] That is to say, there is a gap between adjacent stacks of round caps 2, and the round caps 2 in the stack have several gaps. When the edge of the first round cap 2 abuts against the first tooth 111 of the gear 11, the gear 11 rotates as the round caps 2 are transported, and the second tooth 111 extends into the gap between the first round cap 2 and the second round cap 2, so that the tooth 111 extends into the gap one by one according to the rotation direction. The encoder 12 is connected to the gear 11 to detect the rotation angle of the gear 11, and then transmits it to the PLC for conversion, and calculates the number of round caps 2. It can also be understood that the several gaps formed by the stacking of round caps 2 are equivalent to the rack, the round caps 2 are equivalent to the tooth 111 of the rack, the transport of the round caps 2 is equivalent to the movement of the rack, and when the round caps 2 are transported, the tooth 111 of the rack corresponds to the tooth 111 of the gear 11 one by one.

[0027] Thus, when a plurality of round caps 2 are conveyed, they contact a plurality of teeth 111 on the gear 11 one by one, so that the gear 11 rotates passively; the encoder 12 detects the rotation angle of the gear 11 and calculates the number of round caps 2. The counting device has a simple structure, can accurately count the round caps 2 in the stack, has strong versatility, and does not cause damage to the round caps 2.

[0028] Optionally, the gear 11 is movably disposed between a position close to and a position far from the round cover 2. It can be understood that by movably disposing the gear 11 between a position close to and a position far from the round cover 2, the count of round covers 2 of different specifications and sizes can be matched, thereby improving versatility. The gear 11 may be a nylon gear 11, or a metal gear 11 with rubber coating on the tooth portion 111, thereby further ensuring that the round cover 2 is not damaged.

[0029] Optionally, the counting assembly 1 includes a first mounting seat 13, the gear 11 is mounted on a rotating shaft 18, the rotating shaft 18 is rotatably connected to the first mounting seat 13, and the encoder 12 is connected to the rotating shaft 18. The arrangement of the rotating shaft 18 facilitates the mounting of the gear 11 on the first mounting seat 13 and the connection of the encoder 12. One end of the rotating shaft 18 is connected to the mounting seat through a bearing, the other end of the rotating shaft 18 is connected to the encoder 12, and the fixed end of the encoder 12 is mounted on the first mounting seat 13.

[0030] Furthermore, the counting assembly 1 further includes a second mounting seat 14 and an adjusting member 15, the first mounting seat 13 is movably connected to the second mounting seat 14, and the adjusting member 15 connects the first mounting seat 13 and the second mounting seat 14 to adjust the distance between the first mounting seat 13 and the second mounting seat 14. It can be understood that by cooperating with the second mounting seat 14, the relative distance between the first mounting seat 13 and the second mounting seat 14 can be adjusted, thereby adjusting the relative distance between the gear 11 and the round cover 2, thereby improving the versatility of the counting assembly 1. The connection between the adjusting member and the first mounting seat 13 and the second mounting seat 14 can be through a threaded connection.

[0031] Further, the first mounting seat 13 is mounted on the second mounting seat 14 via a moving pair 16. It can be understood that the moving pair 16 can facilitate the first mounting seat 13 to move relative to the second mounting seat 14, thereby adjusting the distance between the gear 11 and the round cover 2.

[0032] Furthermore, the adjustment assembly further includes a connecting plate 17, the adjustment member 15 is disposed on the connecting plate 17, and the adjustment member 15 is connected to the first mounting seat 13. It can be understood that the connection plate 17 is provided to facilitate the installation of the adjustment member and facilitate the connection of the adjustment member to the first mounting seat 13, thereby reducing the processing cost of the first mounting seat 13 and the second mounting seat 14. The adjustment member can be an adjustment screw.

[0033] Furthermore, the rotating shaft 18 is connected to the first mounting seat 13 in a damped rotational manner. It can be understood that when the round cover 2 drives the gear 11 to rotate, the gear 11 has inertia, and the gear 11 may continue to rotate after the round cover 2 finishes counting, thereby affecting the accuracy of the counting. The damping setting of the rotating shaft 18 can make the gear 11 stop rotating immediately after it is out of contact with the round cover 2, thereby ensuring the accuracy of the counting.

[0034] Optionally, the gear 11 is arranged just above the conveying passage. It is understandable that by arranging the gear 11 just above the conveying passage, the upper space of the device can be fully utilized, and the meshing degree between the tooth portion 111 and the round cover 2 can be improved.
