Description

Technical Field

[0001] This application relates to the field of canning and packaging technology, and in particular to a pull-tab cap feeder. Background Technology

[0002] The function of a cap sorter is to quickly organize and arrange disordered caps and accurately deliver them to the capping position to ensure smooth capping. The accuracy and speed of cap sorting directly affect the capacity of the filling production line. Pull-ring caps are a type of irregular cap, and ordinary cap sorters are not suitable for sorting pull-ring caps.

[0003] In existing technologies, common pull-ring cap feeders mainly use a motor to drive a support plate, rotary table, pad, and pull-ring caps in the cap hopper to rotate together, achieving automatic feeding of pull-ring caps. Through an air pipe, quick-connect coupling, and outlet upper limit block, the pull-ring caps continuously change direction while moving, so that the cap part matches the cap through the cap groove. The pull-ring part continuously adjusts and adapts to the pull-ring groove, ensuring that the pull-ring cap can move smoothly within the outlet upper limit block. The cap channel limit block and cap channel cover plate transport the pull-ring caps to the baffle plate, which then stops and releases the caps, thus achieving the needs of rapid sorting, sequencing, and feeding of pull-ring caps.

[0004] However, the capacity of the rotary table is limited. After running for a period of time, once all the bottle caps in the device have been conveyed, bottle caps need to be added back to the rotary table. In the traditional technology, during the production process of the cap feeder, the number of pull ring caps in the rotary table is mainly monitored manually in real time, and the pull ring caps are stopped when the stock in the rotary table is low so that they can be replenished. This is quite labor-intensive and needs improvement. Utility Model Content

[0005] In order to achieve the technical effect of automatically monitoring the inventory of pull ring caps in the rotary table, this application provides a pull ring cap sorting device.

[0006] The pull-ring cap unloader provided in this application adopts the following technical solution:

[0007] A pull-tab lid unloader mainly includes a lid unloader and a mounting bracket. The mounting bracket is fixedly installed on the ground beside the lid unloader. A mounting arm is rotatably and adjustablely mounted on the mounting bracket. A locking structure for locking or releasing the mounting arm is installed on the mounting bracket; and:

[0008] The counting unit is fixedly installed on the side of the cap channel of the cap feeder, and is used to detect the number of pull ring caps passing through the cap channel and output a detection control signal when the number of caps reaches a set value or an integer multiple of the set value.

[0009] An image detection unit is fixedly mounted on the mounting arm and connected to the signal output terminal of the counting unit. It is used to receive the detection control signal, detect the amount of pull ring covers in the rotary table, and output an alarm control signal when the amount of pull ring covers in the rotary table is too low.

[0010] A buzzer is fixedly mounted on the mounting arm and connected to the signal output terminal of the image detection unit. It is used to receive the alarm control signal and emit an alarm sound.

[0011] By adopting the above technical solution, before the cap feeder is put into use, the operator can place the pull-ring caps inside the rotary table and adjust the position of the mounting arm so that the image detection unit on the mounting arm is mounted above the rotary table. During the actual operation of the cap feeder, the counting unit monitors the number of pull-ring caps sent out through the cap channel in real time. When the number of pull-ring caps sent out reaches a set value or an integer multiple of the set value, the counting unit outputs a detection control signal. The image detection unit receives the detection control signal and collects image data inside the rotary table, and calculates the amount of pull-ring caps in the rotary table based on the obtained image data. When the amount of pull-ring caps in the rotary table is too low, the image detection unit controls the buzzer to sound an alarm, prompting the on-site operator to replenish the pull-ring caps in the rotary table in time. This eliminates the need for the operator to monitor the quantity in the rotary table in real time, saving manpower.

[0012] Preferably, the mounting arm is rotatably mounted on the top of the mounting bracket via a pivot. The locking structure includes a slot, a positioning hole, and a positioning rod. The slot is located on the top of the mounting bracket, the positioning hole extends through the mounting arm, and the positioning rod is inserted into the positioning hole and the slot.

[0013] By adopting the above technical solution, when the operator needs to rotate the mounting arm so that the image detection unit on the mounting arm is mounted above the rotary table, the operator can insert the positioning rod into the positioning hole and slot, and the positioning rod locks the position of the mounting arm.

[0014] Preferably, a connecting seat is fixedly installed on the cover channel, and the counting unit includes:

[0015] The sensor hole is opened through the side wall of the cover channel, connecting the pull ring groove inside the cover channel with the external space;

[0016] An ultrasonic ranging sensor is fixedly installed on the connector, with the sensing end facing the sensing hole, and is used to detect the distance between itself and the obstructing surface in front and output a sensing distance signal.

[0017] The comparator chip is connected to the signal output terminal of the ultrasonic ranging sensor to receive the sensing distance signal and output a high-level signal when the sensing distance is less than a set value.

[0018] The first microcontroller is connected to the signal output terminal of the comparator chip and is used to receive the high-level signal, calculate the number of times the high-level signal occurs, and output the detection control signal when the number of times the high-level signal occurs is a set number or an integer multiple of the set number.

[0019] By adopting the above technical solution, when the pull-ring cover is sent out through the cover channel, the pull ring on the top of the pull-ring cover is sent out from the pull-ring groove and passes through the ultrasonic ranging sensor, which reduces the sensing distance measured by the ultrasonic ranging sensor. The comparator chip outputs a high-level signal. After receiving the high-level signal, the first microcontroller calculates the number of occurrences of the high-level signal, which can realize the counting effect of automatically detecting the number of pull-ring covers sent out. At the same time, the first microcontroller can also output a detection control signal when the number of covers sent out reaches a set value or an integer multiple of the set value, so as to control the image detection unit to detect the number of pull-ring covers in the rotary table.

[0020] Preferably, a cover plate is detachably mounted on the top of the rotating disk of the cover feeder, and a through hole is provided in the middle of the cover plate. The image detection unit includes:

[0021] A CCD camera is detachably mounted on the mounting arm, positioned above the rotary table, and connected to the signal output terminal of the first microcontroller. It is used to receive the detection and control signals and acquire image data within the rotary table.

[0022] An image processor, connected to the data output terminal of the CCD camera, is used to receive the image data and calculate the amount of pull ring cover in the rotating disk;

[0023] The second microcontroller is connected to the signal output terminal of the image processor and is used to output the alarm control signal when the number of pull ring covers in the rotary disk is less than a set value.

[0024] By adopting the above technical solution, the CCD camera can collect image data inside the rotating disk. The data processor performs grayscale processing and calculation on the image data. When the number of pull ring covers in the rotating disk is too small, the proportion of the pull ring covers in the image data becomes smaller, and the grayscale value calculated by the image processor becomes smaller. When the grayscale value is less than the set value, it can be determined that the number of pull ring covers in the rotating disk is too small. The second microcontroller can control the buzzer to emit a warning sound to prompt the operator to replenish the pull ring covers.

[0025] Preferably, the cover plate is made of transparent plastic.

[0026] Preferably, a fill light is fixedly mounted at the bottom of the mounting arm, and the fill light is located next to the CCD camera.

[0027] By adopting the above technical solution, the supplementary light can provide a clear and bright field of view for the CCD camera to acquire image data from the rotating disk.

[0028] In summary, the pull-ring cap dispenser of this application has at least one of the following beneficial technical effects:

[0029] 1. When the pull-ring cover is sent out through the cover channel, the pull ring on the top of the pull-ring cover is sent out from the pull-ring groove and passes through the ultrasonic ranging sensor, which reduces the sensing distance measured by the ultrasonic ranging sensor. The comparator chip outputs a high-level signal. After receiving the high-level signal, the first microcontroller calculates the number of occurrences of the high-level signal, which can realize the counting effect of automatically detecting the number of pull-ring covers sent out. At the same time, the first microcontroller can also output a detection control signal to control the image detection unit to detect the number of pull-ring covers in the rotary table when the number of covers sent out reaches a set value or an integer multiple of the set value.

[0030] 2. The CCD camera can capture image data inside the rotating disk. The data processor performs grayscale processing and calculation on the image data. When the number of pull ring covers in the rotating disk is too small, the proportion of the pull ring covers in the image data becomes smaller, and the grayscale value calculated by the image processor becomes smaller. When the grayscale value is less than the set value, it can be determined that the number of pull ring covers in the rotating disk is too small. The second microcontroller can control the buzzer to emit a warning sound to prompt the operator to replenish the pull ring covers. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0036] Example

[0037] This application discloses a pull-ring cap dispenser. (Refer to...) Figures 1-3It mainly includes a lid feeder and a mounting bracket 1. The mounting bracket 1 is fixedly installed on the ground next to the lid feeder. The mounting bracket 1 is rotatably and adjustablely mounted with a mounting arm 11. The mounting bracket 1 is equipped with a locking structure for locking or releasing the mounting arm 11.

[0038] In addition: a counting unit, fixedly installed beside the cap channel 4 of the cap feeder, used to detect the number of pull-ring caps passing through the cap channel 4 and output a detection control signal when the number of caps reaches a set value or an integer multiple of the set value; an image detection unit, fixedly installed on the mounting arm 11 and connected to the signal output terminal of the counting unit, used to receive the detection control signal and detect the amount of pull-ring caps in the rotary table 3, and output an alarm control signal when the amount of pull-ring caps in the rotary table 3 is too low; and a buzzer 2, fixedly installed on the mounting arm 11 and connected to the signal output terminal of the image detection unit, used to receive the alarm control signal and emit a warning sound.

[0039] Before the cap feeder is put into use, the operator can place the pull-ring caps inside the rotary table 3 and adjust the position of the mounting arm 11 so that the image detection unit on the mounting arm 11 is mounted above the rotary table 3. During the actual operation of the cap feeder, the counting unit monitors the number of pull-ring caps sent out through the cap channel 4 in real time. When the number of pull-ring caps sent out reaches the set value or an integer multiple of the set value, the counting unit outputs a detection control signal. The image detection unit receives the detection control signal and collects image data inside the rotary table 3, and calculates the amount of pull-ring caps in the rotary table 3 based on the obtained image data. When the amount of pull-ring caps in the rotary table 3 is too low, the image detection unit controls the buzzer 2 to sound an alarm, prompting the on-site operator to replenish the pull-ring caps in the rotary table 3 in time. This eliminates the need for the operator to monitor the number of pull-ring caps in the rotary table 3 in real time, saving manpower.

[0040] Reference Figure 1 and Figure 2 The mounting arm 11 is rotatably mounted on the top of the mounting bracket 1 via a pivot. The locking structure includes a slot 12, a positioning hole 13, and a positioning rod 14. The slot 12 is opened on the top of the mounting bracket 1, the positioning hole 13 is opened through the mounting arm 11, and the positioning rod 14 is inserted into the positioning hole 13 and the slot 12.

[0041] When the operator needs to rotate the mounting arm 11 so that the image detection unit on the mounting arm 11 is mounted above the rotary table 3, the operator can insert the positioning rod 14 into the positioning hole 13 and the slot 12, and the positioning rod 14 locks the position of the mounting arm 11.

[0042] Reference Figure 1 and Figure 3A connecting base is fixedly installed on the cover channel 4. The counting unit includes: a sensing hole 41, which is opened through the side wall of the cover channel 4 and connects the pull ring groove 42 inside the cover channel 4 with the external space; an ultrasonic ranging sensor 5, which is fixedly installed on the connecting base, with the sensing end facing the sensing hole 41, for detecting the distance between itself and the obstructing surface in front and outputting a sensing distance signal; a comparator chip, which is connected to the signal output terminal of the ultrasonic ranging sensor 5, for receiving the sensing distance signal and outputting a high-level signal when the sensing distance is less than a set value; and a first microcontroller, which is connected to the signal output terminal of the comparator chip, for receiving the high-level signal and calculating the number of occurrences of the high-level signal, and outputting a detection control signal when the number of occurrences of the high-level signal is a set number or an integer multiple of the set number.

[0043] When the pull-ring cover is sent out through the cover channel 4, the pull ring on the top of the pull-ring cover is sent out from the pull-ring groove 42 and passes through the ultrasonic ranging sensor 5, which reduces the sensing distance measured by the ultrasonic ranging sensor 5. The comparator chip outputs a high-level signal. After receiving the high-level signal, the first microcontroller calculates the number of times the high-level signal appears, which can realize the counting effect of automatically detecting the number of pull-ring covers sent out. At the same time, the first microcontroller can also output a detection control signal when the number of covers sent out reaches a set value or an integer multiple of the set value, so as to control the image detection unit to detect the number of pull-ring covers in the rotary disk 3.

[0044] Reference Figure 1 and Figure 2 The top of the rotating disk 3 of the lid sorter is detachably fitted with a transparent plastic cover 31. A through hole 32 is provided in the middle of the cover 31. The image detection unit includes: a CCD camera 6, which is detachably mounted on the mounting arm 11 and erected above the rotating disk 3. It is connected to the signal output terminal of the first microcontroller and is used to receive detection control signals and collect image data inside the rotating disk 3; an image processor, which is connected to the data output terminal of the CCD camera 6 and is used to receive image data and calculate the number of pull ring covers inside the rotating disk 3; and a second microcontroller, which is connected to the signal output terminal of the image processor and is used to output an alarm control signal when the number of pull ring covers inside the rotating disk 3 is less than a set value.

[0045] The CCD camera 6 can acquire image data within the rotary disk 3. The data processor performs grayscale processing and calculation on the image data. When the number of pull ring covers in the rotary disk 3 is too small, the proportion of the pull ring covers in the image data becomes smaller, and the grayscale value calculated by the image processor becomes smaller. When the grayscale value is less than the set value, it can be determined that the number of pull ring covers in the rotary disk 3 is too small. The second microcontroller can control the buzzer 2 to emit a warning sound to prompt the operator to replenish the pull ring covers.

[0046] Reference Figure 2A supplementary light 7 is fixedly mounted on the bottom of the mounting arm 11, and the supplementary light 7 is located next to the CCD camera 6. The supplementary light 7 provides a clear and bright field of view for the CCD camera 6 to acquire image data from the rotating disk 3.

[0047] The implementation principle of the pull-ring cap dispenser in this application embodiment is as follows: When the pull-ring cap is delivered through the cap channel 4, the pull ring on the top of the pull-ring cap is delivered from the pull-ring groove 42 and passes through the ultrasonic ranging sensor 5, causing the sensing distance measured by the ultrasonic ranging sensor 5 to decrease. The comparator chip outputs a high-level signal. After receiving the high-level signal, the first microcontroller calculates the number of occurrences of the high-level signal, which can realize the counting effect of automatically detecting the number of pull-ring caps dispensed. At the same time, the first microcontroller can also output a detection signal when the number of dispensing caps reaches a set value or an integer multiple of the set value. The control signal controls the image detection unit to detect the number of pull ring covers in the rotary disk 3; the CCD camera 6 can collect image data in the rotary disk 3, and the data processor performs grayscale processing and calculation on the image data. When the number of pull ring covers in the rotary disk 3 is too small, the proportion of the pull ring covers in the image data becomes smaller, and the grayscale value calculated by the image processor becomes smaller. When the grayscale value is less than the set value, it can be determined that the number of pull ring covers in the rotary disk 3 is too small. The second microcontroller can control the buzzer 2 to emit a warning sound to prompt the operator to replenish the pull ring covers.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
