Description

Technical Field

[0001] The utility model relates to the field of conveying, in particular to a conveying device with a counting mechanism. 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 in front and behind are prone to be connected end to end and stacked together. Such materials are prone to cause the counting unit to undercount or miss when passing through the counting unit, thereby causing counting errors. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems and provide a conveying device with a counting mechanism, which can reduce the phenomenon of counting errors.

[0005] To achieve the above objectives, the technical solution adopted in the present application is a conveying device with a counting mechanism, comprising a loading section, a transport section and a counting section arranged in the same direction, the loading section comprising a conveyor and a limiting mechanism for limiting the height of materials passing through the conveyor; the transport section comprises a conveying part arranged along the material moving direction, and the conveying speed of the conveying part gradually increases along the material moving direction; the counting section comprises a transmission part and a detection unit for detecting materials, two of the detection units are arranged at intervals along the material moving direction, and the distance between the detection units is adapted to the size of the material, and it also includes a control unit for judging the amount of material between the two detection units by analyzing the signals from the two detection units.

[0006] Furthermore, the limiting mechanism includes a rotating part arranged above the conveyor belt of the conveyor, the rotating part is arranged along the width direction of the conveyor, and a limiting plate is arranged on the outer side wall of the rotating part.

[0007] Furthermore, material baffles are arranged at intervals on the conveyor belt of the conveyor along its conveying direction, and the material baffles are arranged along the width direction of the conveyor.

[0008] The beneficial effects of the present application are as follows: the feeding mechanism and the like place the material in the feeding section, and the feeding section moves the material to the transport section. When the material passes through the limiting mechanism, the limiting mechanism blocks the material pile that is too high due to complete overlap or the number of stacks exceeding two, and pushes down the material pile through the limiting mechanism to avoid the material from completely overlapping. Then the material moves to the transport section. Since the conveying speeds of the conveying parts in the transport section are different, even if two materials partially overlap, when the two materials move to different conveying parts, due to the different speeds, the two materials have a speed difference, and then the two materials are pulled apart, further avoiding the overlapping of the materials. Subsequently, the material passes through the counting section, and the material continues to move under the action of the transmission part. At this time, when the detection unit in front of the material moving direction detects the material, and the other detection unit does not detect the material, one material is counted. When two detection units detect the material, it is counted as two materials to reduce the phenomenon of counting errors. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[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 1-3As shown, the structure of this embodiment is: a conveying device with a counting mechanism, which includes a feeding section 1, a transport section 2 and a counting section 3 arranged in the same direction, the feeding section 1 includes a conveyor 101 and a limiting mechanism for limiting the passing height of materials on the conveyor, and the limiting mechanism can adopt a fixed height limit plate, etc.; the transport section 2 includes a conveying part 201 arranged along the material moving direction, and the conveying part 201 in this embodiment is provided with three sections, and the conveying speed of the conveying part 201 gradually increases along the material moving direction; the counting section 3 includes a transmission part 301, and two brackets 302 are arranged above the transmission part 301 along the material moving direction at intervals, and a detection unit 303 for detecting the material is arranged on the bracket 302, and two detection units 303 are arranged along the material moving direction at intervals, and the detection unit 303 can adopt a proximity switch, a grating, etc. For the convenience of describing the working process, the detection unit 303 is named as a front detection unit and a rear inspection unit, and the distance between the front detection unit and the rear inspection unit is greater than the size of the material in the transportation direction.

[0015] The conveyor 101, the conveying part 201 and the transmission part 301 can adopt linear conveying mechanisms such as belt conveyors; the transmission part 301 can also adopt rollers arranged at intervals. The upper end surface of the conveyor 101 on the side of the transport section 2 is not lower than the upper end surface of the conveying part 201, and baffles are arranged on both sides of the conveyor 101 and the conveying part 201 (for schematic structure, Figure 2 , Figure 3 The baffle on one side is hidden) to ensure that the materials move in the same direction.

[0016] Specific working process: Materials are placed on the conveyor belt of conveyor 101 manually or by a feeding mechanism, and conveyor 101 moves to transport section 2 carrying the materials. The distance between the limiting mechanism and the conveyor belt of conveyor 101 is greater than the height of one material, but less than the height when two materials completely overlap. In this way, when the materials pass through the limiting mechanism, the material pile whose height exceeds the distance between the conveyor belt of conveyor 101 and the limiting mechanism is pushed down to prevent two materials from completely overlapping. Conveyor 101 carries the materials to the conveying section 201 of transport section 2. Since the conveying speeds of the conveying section 201 are different, even if the two materials partially overlap, when the two materials move to different conveying sections 201, the two materials will have a speed difference, which will cause the two materials to be pulled apart, further preventing the materials from overlapping.

[0017] The material is sent to the transmission part 301 by the transport section 2, and the transmission part 301 continues to move with the material. When the front side of the material passes through the rear inspection unit and moves to the front detection unit, the front detection unit detects the material and sends a signal to the control unit connected to the front detection unit and the rear inspection unit. The control unit analyzes and records the signal of the front detection unit. At this time, the rear inspection unit also detects the material. When the rear inspection unit does not detect the material, it means that the material does not overlap. At this time, the control unit analyzes the signals of the two detection units 303 and counts a number.

[0018] If after the materials pass through the loading section 1 and the transport section 2, there are still a few adjacent materials that overlap head to tail, and when such two materials pass through the front and rear inspection units 303, both the front and rear inspection units 303 will detect the materials. At this time, it means that the size of the material between the front inspection unit and the rear inspection unit is larger than the size of the material itself, and two numbers are counted.

[0019] Embodiment 2, as Figure 1-3 As shown, other structures and working processes of this embodiment can refer to Example 1, but the limiting mechanism described in this embodiment includes a rotating part 103 arranged above the conveyor belt of the conveyor 101, the cross-section of the rotating part 103 is circular and rotates under the drive of a motor, etc., the rotating axis of the rotating part 103 is arranged along the width direction of the conveyor 101, and a limiting plate 104 is arranged on the outer side wall of the rotating part 103; the conveyor belt of the conveyor 101 is provided with baffle plates 102 at intervals along its conveying direction, and the baffle plates 102 are arranged along the width direction of the conveyor 101.

[0020] Specific working process: the conveyor 101 carries the material and moves to the transport section 2. The conveying speed of the conveyor 101 is adapted to the rotation speed of the rotating part 103, so that when the limit plate 104 is facing downward, a baffle plate 102 moves to the bottom of the limit plate 104. At this time, the distance between the limit plate 104 and the baffle plate 102 can limit the height that the material can pass through. Through the movement of the conveyor 101 and the rotation of the rotating part 103, the material above the two baffle plates 102 is swept down, or the two materials are prevented from completely overlapping.
