Abstract
Description
Technical Field
[0001] The utility model relates to the field of material transportation, in particular to a packaging system with a counting mechanism. Background Art
[0002] When packaging materials with certain size values, multiple materials are often put into one packaging bag. In order to ensure that the number of materials in each packaging bag is exactly the same in the packaging of the same specification, an automatic counting system is generally used in the process of automated packaging. Its working principle is that under the drive of the conveying device, the materials pass through the detection unit in turn, and the detection unit accurately counts the materials passing through.
[0003] However, when conveying materials, it is easy for two adjacent materials to be stacked end to end. When the stacked materials pass through the counter, it is easy for the counter to undercount or miss a count, which in turn causes the quantity of materials loaded into the packaging bag to fail to meet the requirements. Utility Model Content
[0004] The purpose of the utility model is to provide a packaging system with a counting mechanism to improve the counting accuracy in view of the above problems.
[0005] To achieve the above purpose, the technical solution adopted in the present application is a packaging system with a counting mechanism, which includes material channels arranged side by side, the material channels include a transport mechanism and a material discharge mechanism, the transport mechanism includes a connecting section, a separation section and a counting section in sequence along the material moving direction, the connecting section includes a connecting conveying mechanism and a material blocking mechanism, the material blocking mechanism is arranged above the connecting conveying mechanism, and the material passes through the space between the connecting conveying mechanism and the material blocking mechanism and moves to the separation section; at least two conveying sections are arranged in the separation section, and the conveying speeds of different conveying sections gradually increase along the material moving direction; the counting section includes a transmission section and a detection unit for detecting materials, and two detection units are arranged at intervals along the material moving direction; the material discharge mechanism includes a material discharge pipe with an open upper end, and a material blocking plate group is arranged at the lower end of the material discharge pipe.
[0006] Furthermore, the conveyor belt of the connecting conveying mechanism is provided with partitions at intervals along its conveying direction, and the partitions are provided along the width direction of the connecting conveying mechanism. The material blocking mechanism includes a rotating part, and the rotating part is provided along the width direction of the connecting conveying mechanism. A limiting plate is provided on the outer side wall of the rotating part. The material passes through the space between the limiting plate and the conveyor belt of the connecting conveying mechanism to avoid two materials from completely overlapping each other.
[0007] Furthermore, the baffle plate group includes baffle plates that are arranged opposite to each other in the transverse direction, and the upper ends of the baffle plates are rotatably connected to the side walls of the discharge pipe.
[0008] Furthermore, the feeding pipes are arranged in a vertical direction to carry out layered feeding.
[0009] Furthermore, in order to improve the accuracy of material discharge and adapt to the packaging mechanism during high-speed movement, the conveying part near the counting section and other conveying parts are driven by different driving mechanisms, so that the conveying part close to the counting section can work independently, so that when other conveying parts and the connecting conveying mechanism stop working, the material located on the conveying part close to the counting section can be put into the upper discharge pipe.
[0010] Furthermore, it also includes a feeding mechanism, which includes a silo and a feeding conveying mechanism. The lower part of the feeding conveying mechanism is located in the silo, and the upper part of the feeding conveying mechanism extends upward to be located above the connecting conveying mechanism to achieve automatic feeding and improve the level of automation.
[0011] Furthermore, the feeding mechanism also includes a side conveying mechanism and a lower conveying mechanism. The side conveying mechanism is arranged on one side of the feeding conveying mechanism and is located above the silo, and the lower conveying mechanism is located below the connecting conveying mechanism. The side conveying mechanism is connected to the lower conveying mechanism to return the excess material on the connecting section to the feeding area of the feeding conveying mechanism of the silo.
[0012] The beneficial effects of the present application are as follows: the connecting conveying mechanism moves the material to one side of the feeding mechanism, and the distance between the connecting conveying mechanism and the material blocking mechanism can limit the height that the material can pass through, so as to avoid two materials from completely overlapping each other. Then the material moves to the separation section. Since the conveying speeds of the conveying parts in the separation section are different, even if the 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, so that the materials can be passed through the detection unit one by one as much as possible; then 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, and when two detection units detect the material, it is counted as two materials to reduce the phenomenon of counting errors.

[0022] 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.
[0023] Embodiment 1, as Figure 1-8 As shown, the structure of this embodiment is: a packaging system with a counting mechanism, which includes a material channel arranged side by side, the material channel includes a transport mechanism 1 and a feeding mechanism 2, the transport mechanism includes a connecting section, a separation section and a counting section in sequence along the material moving direction, the connecting section includes a connecting conveying mechanism 3 and a material blocking mechanism, the material blocking mechanism is arranged above the connecting conveying mechanism 3, and the material passes through the space between the connecting conveying mechanism 3 and the material blocking mechanism and moves to the separation section; the material blocking mechanism can adopt a fixed height limit plate, etc. In this embodiment, the material blocking mechanism includes a rotating part 8, the rotating part 8 is arranged along the width direction of the connecting conveying mechanism 3, and a limiting plate 9 is arranged on the outer side wall of the rotating part 8, and at the same time, the conveyor belt of the connecting conveying mechanism 3 is provided with partitions 7 at intervals along its conveying direction, and the partitions 7 are arranged along the width direction of the connecting conveying mechanism 3; at least two sections of conveying parts 4 are arranged in the separation section, and the conveying speeds of different conveying parts 4 gradually increase along the material moving direction. The conveying part 4 in this embodiment is provided with three sections.
[0024] The counting section includes a transmission part 10 and a detection unit 6 for detecting materials. Two detection units 6 are arranged at intervals along the material moving direction. The detection unit 6 in this embodiment is arranged on a bracket 11. The detection unit 6 can adopt a proximity switch, a grating, etc. For the convenience of describing the working process, the detection units 6 are named as front detection units and rear inspection units in this embodiment. The distance between the front detection unit and the rear inspection unit is greater than the size of the material in the transportation direction, but less than the length of the two materials connected end to end; the unloading mechanism 2 includes an unloading pipe 5 with an open upper end, and a baffle plate group is arranged at the lower end of the unloading pipe 5. The baffle plate group includes baffle plates 13 arranged opposite to each other in the transverse direction, and the upper end of the baffle plate 13 is rotatably connected to the side wall of the unloading pipe 5. The transmission part 10, the connecting conveying mechanism 3 and the conveying part 4 can adopt linear transmission mechanisms such as belt conveyors.
[0025] Specific working process: the upper end surface of the connecting conveying mechanism 3 on the separation section side is not lower than the upper end surface of the conveying part 4, and baffles 12 (for schematic structure, Figure 5 , Figure 6 The baffle on one side is hidden) to ensure that the materials move in the same direction. The materials are placed on the conveyor belt of the connecting conveying mechanism 3 manually or by a feeding device. The connecting conveying mechanism 3 carries the materials to the separation section. The conveying speed of the connecting conveying mechanism 3 is adapted to the rotation speed of the rotating part 8, so that when the limit plate 9 is facing downward, a partition 7 moves below the limit plate 9. At this time, the distance between the limit plate 9 and the partition 7 is greater than the height of a single material, but less than the height when the two materials completely overlap, so as to achieve the effect of limiting the height of the material passing. Through the movement of the connecting conveying mechanism 3 and the rotation of the rotating part 8, the materials between the two partitions 7 on the upper side are swept down, or the two materials are prevented from completely overlapping. The connecting conveying mechanism 3 carries the materials to the conveying part 4 of the separation section. Due to the different conveying speeds of the conveying part 4, even if the two materials partially overlap, when the two materials move to different conveying parts 4, the two materials have a speed difference, which will cause the two materials to be pulled apart, further ensuring that the materials will not completely overlap.
[0026] The material in the separation section then moves to the transmission section 10 of the counting section. Then, driven by the transmission section 10, the material moves to the front detection unit after passing through the rear inspection unit. At this time, 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 6 and counts one number.
[0027] If the ends of two adjacent materials overlap, and such materials pass through the front and rear inspection units 6, both the front and rear inspection units 6 will detect the materials. This 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.
[0028] The counted material enters the feeding tube 5 from the upper end thereof, and is first blocked by the blocking plate 13 in the blocking plate group, and the connecting conveying mechanism 3 and the conveying part 4 in the material channel stop working. When the material in the material channel is needed, the blocking plates 13 on both sides are opened by the cylinder, the electric push rod, etc., so that the material falls out. After the material falls out, the blocking plate 13 is reset to the closed state, and the transmission part 10, the connecting conveying mechanism 3 and the conveying part 4 start working again.
[0029] Embodiment 2, as Figure 4-8 As shown, the other structures and working processes of this embodiment can refer to Example 1, but the feed pipes described in this embodiment are arranged vertically, and the two upper and lower adjacent feed pipes 5 are sleeved. In this embodiment, two feed pipes 5 are set for illustration, and they are named as the first feed pipe and the second feed pipe from top to bottom. The conveying part 4 at the proximal end of the counting section is driven by an independent motor, so that it uses a different driving mechanism from other conveying parts 4.
[0030] Specific working process: eight materials are required at a time. Before packaging, the baffle plate group of the first feeding tube is in an open state, and the baffle plate group of the second feeding tube is in a closed state. The transport mechanism 1 in different material channels transports the materials to the feeding mechanism 2. When the number of materials in the second feeding tube in a material channel is two, the single chip microcomputer in the control unit records the data, and the baffle plate group of the first feeding tube moves to a closed state. At the same time, the connecting conveying mechanism 3 in the material channel and the remaining conveying parts 4 except the conveying part 4 closest to the transmission part 10 stop working. The transmission part 10 and the conveying part 4 closest to the transmission part 10 continue to work to put the materials carried on them into the first feeding tube. At this time, the materials in the remaining material channels are also transporting materials at the same time. The control unit counts and calculates the materials in the second feeding tubes in all material channels respectively. When the sum can be eight, the control unit controls the baffle plate groups on the second feeding tubes in these material channels to open, so that the materials in these object channels fall onto the feeding belt together. After the material in the second feeding pipe falls out, the baffle plate group in the second feeding pipe is closed again, and the baffle plate group in the first feeding pipe is opened, so that the material falls into the second feeding pipe for packaging. When there is no material in both the first feeding pipe and the second feeding pipe, the connecting conveying mechanism 3 and the stopped conveying part 4 resume operation.
[0031] Embodiment 3, as Figure 1-3As shown, other structures and working processes of this embodiment can refer to embodiment 1 or 2, but in this embodiment, it also includes a feeding mechanism 14, the feeding mechanism 14 includes a silo 15 and a feeding conveying mechanism 16, the feeding conveying mechanism 16 can adopt an elevator, a belt conveyor, etc., the lower part of the feeding conveying mechanism 16 is located in the silo 15, and the upper part of the feeding conveying mechanism 16 extends upward to be located above the connecting conveying mechanism 3.
[0032] The feeding mechanism 14 further includes a side conveying mechanism 17 and a lower conveying mechanism 18 . The side conveying mechanism 17 is arranged on one side of the feeding conveying mechanism 16 and located above the silo 15 . The lower conveying mechanism 18 is located below the connecting conveying mechanism 3 . The side conveying mechanism 17 is connected to the lower conveying mechanism 18 .
[0033] Specific working process: the side conveying mechanism 17 and the lower conveying mechanism 18 can adopt belt conveyors, and the excess materials on the connecting conveying mechanism 3 fall onto the lower conveying mechanism 18. Under the conveyance of the lower conveying mechanism 18, the materials fall onto the side conveying mechanism 17, and then the side conveying mechanism 17 delivers the materials to the loading area of the loading conveying mechanism 16 in the silo 15, and the loading conveying mechanism 16 delivers the materials to the connecting conveying mechanism 3 again.

The above examples are only used to help understand the method and core ideas of the utility model. The above is only the preferred implementation method of the utility model. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures.
