Description

Technical Field

[0001] The present invention relates to the technical field of packaging, especially the technical field of gummy candy packaging. Background Art

[0002] Strip-shaped gummy candies are packaged in boxes. When using this packaging method, the traditional method is to manually put the gummy candies into the box body. Such a method has a high labor intensity and low production efficiency.

[0003] Currently, there are devices on the market for automatically packaging candies. For example, CN222098001U discloses a candy automatic feeding and packaging system, which includes a weighing and detecting machine. The weighing and detecting machine is arranged between the feeding and folding box machine and the conveyor belt material transfer machine; the weighing and detecting machine includes a front conveyor belt, a rear conveyor belt, a weighing device and a pushing and dropping robotic arm; the front conveyor belt, the weighing device and the rear conveyor belt are arranged in sequence to form a detection channel; the input end of the detection channel is communicated with the output end of the first conveyor belt, and the output end of the detection channel is communicated with the input end of the second conveyor belt; the pushing and dropping robotic arm is arranged beside the rear conveyor belt and faces above the rear conveyor belt; by setting the weighing and detecting machine, the device can achieve the fixed-weight packaging of candies, but it does not have a candy counting function and cannot achieve the fixed-quantity packaging of candies.

[0004] In order to achieve the fixed-quantity output of candies, the existing patent CN220640393U discloses an equal-quantity intermittent and uniform feeding device. By providing an outer plate between the device frame plate and the outer plate, when feeding, starting the servo motor will drive the connecting material channel to rotate. When feeding, it flows into the connecting material channel through the feeding pipeline. When the height is reached, it will be exported from the material dividing cylinder opening. The equal-quantity partition plate evenly divides the internal space of the material dividing bottom frame. When the connecting material channel drives the material dividing cylinder opening to continuously rotate, the candies fall into the internal compartments of the material dividing bottom frame in sequence. There is a packaging material opening at the bottom of the material dividing bottom frame, and the candies are poured into the corresponding packaging box for packaging operation. The above can perform the packaging action when the gummy candies are evenly released in equal quantities; if the equipment jams or runs out of materials during operation, there will be a problem that the expected output and the actual output are inconsistent.

[0031] The working process of the present invention: During the operation of the gummy candy automatic boxing line of the present invention, the device is mainly used for boxing strip-shaped gummy candies. The entire operation process is controlled by a control device. The candy feeding mechanism conveys the gummy candies one by one onto the telescopic first conveyor belt 2. When the first induction probe 20 detects that a gummy candy has passed by, the pushing and pulling device drives the movable frame 22 to move once. Each time the movable frame 22 moves, the length of the telescopic first conveyor belt 2 experiences a change from the longest to the shortest and then back to the longest. The gummy candies fall into the first receiving box 3. When the number of gummy candies falling into the first receiving box 3 reaches the preset number, if the third induction probe 53 senses the box body 6, the automatic control door opens, and the gummy candies in the first receiving box 3 fall into the lower box body 6. The automatic control door closes after opening for a period of time. When the automatic control door is not fully closed, if the first induction probe 20 detects that a gummy candy has passed by, the pushing and pulling device does not drive the movable frame 22 to move, and at this time the gummy candies will fall into the second receiving box 4; when the number of gummy candies falling into the first receiving box 3 reaches the preset number, if the third induction probe 53 does not sense the box body 6, even if the first induction probe 20 detects that a gummy candy has passed by, the pushing and pulling device does not drive the movable frame 22 to move, and at this time the gummy candies will fall into the second receiving box 4 until the third induction probe 53 detects the box body 6.

[0032] After the gummy candies in the first receiving box 3 fall into the lower box body 6 and the automatic control door closes again, the second cylinder 510 drives the first blocking rod 511 to retreat. When the retreat is completed, the first blocking rod 511 no longer blocks the box body 6, and the box body 6 is taken away by the second conveyor belt 5. After the second cylinder 510 drives the first blocking rod 511 to retreat for a period of time, it resets. Then the third cylinder 520 drives the clamping plate 521 to retreat. When the retreat is completed, the clamping plate 521 no longer clamps the box body 6. The box body 6 originally clamped by the clamping plate 521 moves along with the second conveyor belt 5 until it is blocked by the first blocking rod 511. At this time, the third induction probe 53 can sense the box body 6. Then the clamping plate 521 resets under the drive of the third cylinder 520, and the clamping plate 521 clamps a new box body 6.

[0033] The above embodiments are illustrative of the present invention, not limiting of the present invention. Any solution obtained by simply transforming the present invention belongs to the protection scope of the present invention.
