Description

Technical Field

[0001] The utility model relates to the field of counting equipment, in particular to a counting structure. Background Art

[0002] When packaging materials of a certain size, a conveying device is required to transfer the materials between two devices. In this process, accurate counting of materials is particularly critical. For example, in the packaging process, it is necessary to ensure that the number of materials in each packaging bag of the same specification is exactly the same. In order to improve production efficiency, automatic counting systems are now widely used. Its working principle is that under the drive of the conveying device, the materials pass through the counting unit in turn, and the counting unit accurately counts the materials passing through.

[0003] However, when placing materials on the conveying device, the two adjacent materials are prone to be stacked head to tail. Such materials are prone to cause undercounting or missing of the counting unit when passing through the counting unit, thereby causing counting errors. Utility Model Content

[0004] The purpose of the utility model is to provide a counting structure to reduce the phenomenon of counting errors in view of the above problems.

[0005] To achieve the above objectives, the technical solution adopted in the present application is a counting structure, including a front detection unit and a rear detection unit arranged at intervals along the material conveying direction, and the front detection unit and the rear detection unit are both connected to a counting control system; the material moves to the rear detection unit after passing through the front detection unit, and the front detection unit and the rear detection unit detect the material respectively. When the material is detected by the rear detection unit, the counting control system only receives the detection signal of the rear detection unit and counts one number. When the rear detection unit detects the material and the front detection unit also detects the material at the same time, the counting control system receives the detection signals of the front detection unit and the rear detection unit and counts two numbers.

[0006] Furthermore, the distance between the front detection unit and the rear detection unit is adjustable to accommodate materials of different specifications.

[0007] Furthermore, the front detection unit and the rear detection unit are respectively arranged on a bracket, and the bracket is movably arranged on a frame of the conveying mechanism.

[0008] Furthermore, the bracket is provided with an elongated hole, and the frame of the conveying mechanism is provided with a bolt, and the bolt passes through the elongated hole and is connected with a locking nut.

[0009] The beneficial effects of the present application are as follows: the material moves under the action of the conveying mechanism. When the material moves to be detected by the rear detection unit, if the front detection unit does not detect the material, it is counted as one material. When both the front and rear detection units detect the material, it is counted as two materials to reduce the phenomenon of counting errors. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0014] Embodiment 1, as Figure 1-2 As shown, the structure of this embodiment is: a counting structure, including a front detection unit 1 and a rear detection unit 2 arranged at intervals along the material conveying direction, the front detection unit 1 and the rear detection unit 2 can adopt proximity switches, gratings, photoelectric sensors, etc., the distance between the front detection unit 1 and the rear detection unit 2 is greater than the single size of the detected material but less than twice the size of the detected material; the front detection unit 1 and the rear detection unit 2 are both connected to the counting control system, the counting control system can adopt a single chip microcomputer, etc., which can receive the detection signals of the front detection unit 1 and the rear detection unit 2, and analyze the detection signals, and complete the counting through the analysis results; the counting principle is that the material passes through the front detection unit 1 and the rear detection unit 2 ( Figure 2 The arrow in the figure indicates the direction of material movement), the conveying mechanism can adopt a belt conveyor, a transmission roller, etc. When the front detection unit 1 and the rear detection unit 2 adopt a through-type photoelectric sensor, the conveying mechanism adopts transmission rollers arranged at intervals to facilitate the passage of the light beam. The front detection unit 1 and the rear detection unit 2 detect the material respectively. When the material is detected by the rear detection unit 2 in a single manner, the counting control system only receives the detection signal of the rear detection unit 2 and counts one number. When the material moves in two ways to be detected by the rear detection unit 2, the counting control system receives the detection signals of the front detection unit 1 and the rear detection unit 2 and counts two numbers.

[0015] Specific working process: Materials are placed on the conveying mechanism one by one manually or by feeding equipment. When the materials pass through the front detection unit 1 and are detected by the rear detection unit 2, the rear detection unit 2 sends a signal to the counting control system, and the counting control system analyzes and records the signal of the rear detection unit 2. At this time, the front detection unit 1 also detects the materials. If the front detection unit 1 does not detect the materials, it means that the materials do not overlap, and the counting control system counts one number. If the ends of two adjacent materials overlap, and such materials pass through the front and rear detection units, both the front detection unit 1 and the rear detection unit 2 will detect the materials. At this time, it means that the size of the material between the front detection unit 1 and the rear detection unit 2 is larger than the size of the material itself, and two numbers are counted.

[0016] Embodiment 2, as Figure 1-2 As shown, other structures and working processes of this embodiment can refer to embodiment 1, but in this embodiment, the distance between the front detection unit 1 and the rear detection unit 2 is adjustable to adapt to materials of different specifications. The adjustment method can be to adopt one of the front detection unit 1 and the rear detection unit 2 to be movable, or to adopt both to be movable; in this embodiment, the front detection unit 1 and the rear detection unit 2 are respectively arranged on the bracket 3, and the bracket 3 is movably arranged on the frame 4 of the conveying mechanism. A plurality of screws can be arranged at intervals along the material moving direction on the frame 4 of the conveying mechanism, and a through hole matching the screw is arranged on the bracket 3. The distance between the front detection unit 1 and the rear detection unit 2 can be adjusted by installing the through hole on different screws; in this embodiment, the bracket 3 is provided with a long hole 5, and the frame 4 of the conveying mechanism is provided with a bolt, and the bolt passes through the long hole 5 and is connected with the locking nut. When it is necessary to adjust the distance between the front detection unit 1 and the rear detection unit 2, loosen the locking nut, move the bracket 3, and after the movement is completed, tighten the locking nut again.
