Description

Technical Field

[0001] The invention belongs to the technical field of chopstick packaging, and in particular relates to a paper bag semi-packaging device and a semi-packaging method for chopsticks. Background Art

[0002] On the dining tables of many hotels, there are usually some chopsticks half-packed in exquisite paper bags neatly placed. Each paper bag contains a pair of chopsticks, with the front half of the chopsticks inserted into the paper bag and the back half exposed outside the paper bag. When using, diners can pull out the chopsticks from the paper bag and use them.

[0003] Usually, the size of the head and tail of chopsticks is different, and the center of gravity of chopsticks deviates from the midpoint of the chopsticks. Restaurant workers need to sort the cleaned and dried chopsticks by head and tail first, and then insert the sorted chopsticks into paper packaging bags one by one. The semi-packaging process of paper bags for chopsticks is usually done manually by restaurant workers, with many steps and a cumbersome process, which requires a lot of manpower and time costs.

[0004] The prior art discloses a chopstick packaging device, the working process of which is to use a conveyor chain to convey chopsticks into a chopstick storage box. When the number of chopsticks reaches the packaging number, the control valve opens the baffle to make the chopsticks in the chopstick storage box fall onto the rack; the horizontal manipulator on the rack conveys the chopsticks that have fallen onto the rack to the packaging table, and then the chopsticks are pushed to the packaging and packaging mechanism through the longitudinal pushing arm. The opening end of the packaging bag used to package the chopsticks is pressed under the packaging bag pressure plate, and the packaging bag is blown open by the air flow blown out of the air jet nozzle, and then the motor drives the rotating pillar to rotate 90 degrees to open the packaging bag, and then the chopsticks are pushed into the packaging bag for packaging.

[0005] The above-mentioned chopstick packaging device is mainly used for the factory to mass-produce disposable chopsticks in plastic bags. It does not have the function of sorting the head and tail ends of chopsticks. The method of using airflow to blow open the plastic bag mouth is not suitable for paper bags. Using a rotating support to open the packaging bag is likely to hinder the chopsticks from being pushed into the paper bag. Therefore, the chopstick packaging device is not suitable for semi-packaging of chopsticks in paper bags. And there has been no report on semi-packaging devices for chopsticks in paper bags so far. Summary of the invention

[0006] In view of the technical problems existing in the prior art, one of the purposes of the present invention is to provide a paper bag semi-packaging device for chopsticks, which can smoothly enter the paper bag when the mouth of the paper bag is opened, thereby realizing paper bag semi-packaging of chopsticks, having a simpler structure and control, and saving labor costs and time costs.

[0052] The present invention is described in further detail below.

[0053] like Figure 1 As shown, a paper bag semi-packaging device for chopsticks includes a frame 5 and a control device, and the frame 5 is provided with a chopstick sorting device, a chopstick receiving device, a paper bag storage device 61, a paper bag pushing device, a paper bag opening device and a chopstick pushing device;

[0054] The chopstick sorting device is used to sort the heads and tails of chopsticks and convey them to the chopstick receiving device;

[0055] The chopstick receiving device can accommodate multiple layers of chopsticks, and each layer can accommodate a pair of chopsticks;

[0056] The paper bag storage device 61 is arranged on one side of the chopstick receiving device;

[0057] The paper bag pushing device is arranged corresponding to the paper bag storage device 61, and is used to push out one paper bag in the paper bag storage device 61 each time;

[0058] The paper bag opening device is arranged corresponding to the paper bag pushing device, and is used to clamp the side wall of the paper bag pushed by the paper bag pushing device to open the bag mouth of the paper bag;

[0059] The chopstick pushing device is arranged on one side of the chopstick receiving device and is arranged corresponding to the paper bag opening device, and is used to push a pair of chopsticks in the chopstick receiving device into the paper bag with the bag opening opened;

[0060] The control device is used for controlling the actions of the chopstick sorting device, the paper bag pushing device, the paper bag opening device and the chopstick pushing device.

[0061] The prior art firstly needs to use a pressing plate to press the open end of the plastic bag for packaging and packaging chopsticks, then use an air nozzle to blow open the opening of the plastic bag, and then use a pillar to open the plastic bag. During this process, not only multiple components need to be set and the mutual coordination of each component needs to be controlled, but also when the plastic bag is opened with a pillar, the pillar in the plastic bag blocks the path of the chopsticks entering the plastic bag, which will inevitably hinder the chopsticks from entering the plastic bag, affecting the packaging speed and effect of the chopsticks. This embodiment cleverly utilizes the characteristic that the paper bag is harder than the plastic bag material, and clamps the side wall of the paper bag through the paper bag opening device to automatically open the paper bag mouth, which can not only fix the paper bag, but also quickly open the paper bag mouth, and because the paper bag opening device clamps the side wall of the paper bag, it does not need to enter the paper bag, so it will not block the path of the chopsticks entering the paper bag, and will not hinder the process of the chopsticks entering the paper bag, so that the chopsticks can enter the paper bag smoothly. There is no need to set too many components, the control is simpler, and the paper bag semi-packaging speed and effect of the chopsticks are better.

[0062] The chopsticks sorting device automatically sorts and arranges the heads and tails of the chopsticks, avoiding the trouble of manual sorting. At the same time, the paper bag opening device clamps the side wall of the paper bag to automatically open the bag mouth, and the chopstick pushing device automatically pushes a pair of chopsticks in the chopstick receiving device into the paper bag. This process is repeated, and multiple pairs of sorted and arranged chopsticks can be automatically semi-packed in paper bags, thereby saving a lot of labor costs and time costs, and improving the service efficiency of the restaurant.

[0063] The chopstick sorting device includes a feed hopper 51 and a vibration motor fixed to the frame 5. The width of the feed hopper 51 matches the length of the chopsticks, and the vibration motor is connected to the feed hopper 51. Specifically, the feed hopper 51 is arranged on the top of the frame 5, and includes an inclined slope and vertical plates arranged on both sides of the slope. The distance between the two vertical plates is equal to the length of the chopsticks, and the chopsticks to be sorted are placed between the two vertical plates. A fan is arranged on the vertical plate to dry the chopsticks on the slope. In addition, a disinfection lamp is also arranged on the slope to disinfect the chopsticks.

[0064] An outlet is provided at the end of the slope of the feed hopper 51, and a horizontally arranged dividing rod 13 is externally connected to the middle of the outlet of the feed hopper 51, and the dividing rod 13 is perpendicular to the outlet of the feed hopper 51; guide plates 12 are symmetrically provided on both sides of the dividing rod 13, and the two guide plates 12 gradually narrow from top to bottom and along the extending direction of the dividing rod 13. Specifically, the distance between the two guide plates 12 gradually decreases from top to bottom, and a guide gap is left between the lower ends of the two guide plates 12, and the guide gap gradually decreases from the end close to the feed hopper 51 to the end away from the feed hopper 51; inclined planes 11 are respectively provided below the two guide plates 12, and the slope of the inclined plane 11 is smaller than the slope of the guide plate 12, and the distance between the two inclined planes 11 gradually decreases from top to bottom, and a discharge gap is left between the lower ends of the two inclined planes 11, and the discharge gap corresponds to the chopstick receiving device.

[0065] When in use, a plurality of chopsticks to be sorted are placed horizontally on the slope of the feed hopper 51. The vibration motor is installed at the bottom of the feed hopper 51, and the chopsticks on the slope slide down along the slope after being vibrated. Since the width of the feed hopper 51 matches the length of the chopsticks, when the chopsticks slide down to the dividing rod 13 at the outlet of the feed hopper 51, the midpoint of the chopsticks is located on the dividing rod 13, and the two ends are suspended. Due to the difference in size between the head and the tail of the chopsticks, the center of gravity of the chopsticks deviates from the midpoint of the chopsticks, so the chopsticks will tilt and fall on the heavier side on the dividing rod 13. During the falling process, the chopsticks will first collide with the two guide plates 12 on both sides of the dividing rod 13. Since the two guide plates 12 gradually narrow along the extension direction of the dividing rod 13, their cross-section presents an inverted eight-shaped shape, and the inverted eight-shaped shape gradually shrinks from top to bottom. After the chopsticks collide with the guide plate 12, the motion trajectory is adjusted, and the adjusted chopsticks continue to fall from the guide gap at the lower end of the guide plate 12 to the two inclined surfaces 11 below the guide plate 12. The longitudinal sections of the two inclined surfaces 11 are in an inverted eight-shaped shape, and the inverted eight-shaped shape remains unchanged along the extending direction of the material dividing rod 13. The slope of the inclined surface 11 is smaller than the slope of the guide plate 12, which has the effect of buffering and further adjusting and straightening the movement of the chopsticks, so that the chopsticks are sorted by the head and tail and fall from the discharge gap at the lower end of the inclined surface 11 to the chopstick receiving device below.

[0066] In this embodiment, a guide plate 12 that gradually narrows in both horizontal and vertical directions is set between the dividing rod 13 and the inclined surface 11, so that the movement trajectory of the chopsticks when they fall from the dividing rod 13 is adjusted, thereby avoiding the problem of some chopsticks rolling over when falling from the dividing rod 13 and causing incorrect sorting of the head and tail ends.

[0067] The chopstick receiving device is arranged below the material distribution rod 13, and includes a middle plate 21 arranged in the middle of the discharging gap and two side plates 22 respectively arranged on both sides of the middle plate 21, the top ends of the two side plates 22 are respectively connected to the lower ends of the corresponding inclined planes 11, the middle plate 21 and the two side plates 22 are vertically arranged and parallel to each other, the height of the middle plate 21 is greater than the height of the side plates 22 and the lower ends of the inclined planes 11, and the distance between each side plate 22 and the middle plate 21 matches the outer diameter of the chopsticks. After adopting this structure, each side plate 22 and the middle plate 21 can accommodate a plurality of single chopsticks stacked vertically, and the chopsticks that fall from the discharging gap at the lower end of the inclined plane 11 will be neatly stacked between the side plates 22 and the middle plate 21 by sorting the head and tail, so that the chopstick pushing device can push a pair of chopsticks from the chopstick discharging channel between the bottoms of the two side plates 22 to the paper bag opening device at a time.

[0068] The paper bag storage device 61 is arranged on one side in front of the chopstick receiving device, and is provided with an inner cavity matching the width of the paper bag, and can accommodate multiple layers of single paper bags stacked vertically. A paper outlet gap is provided at the bottom of the inner cavity to allow the paper bag to pass through, and the paper bag pushing device is arranged corresponding to the paper outlet gap, so that an empty paper bag can be pushed out from the paper outlet gap each time, and the bag mouth of the pushed paper bag faces the chopstick receiving device.

[0069] like Figure 2 , Figure 4 As shown, the paper bag opening device is arranged on one side of the paper bag storage device 61, and is arranged corresponding to the paper bag pushing device, including a first servo 31 and a second servo 32 which are arranged on one side of the paper discharge gap in sequence, the first servo 31 and the second servo 32 are respectively provided with a first rocker arm 311 and a second rocker arm 321, the first rocker arm 311 and the second rocker arm 321 are respectively arranged on both sides of the chopstick discharge channel, and the first rocker arm 311 is perpendicular to the second rocker arm 321.

[0070] Specifically, the first steering gear 31 is located on the moving passage after the paper bag is pushed out from the paper discharge gap. When in use, the first steering gear 31 first rotates the first rocker arm 311 so that the first rocker arm 311 gives way to the moving passage of the paper bag, and then the paper bag pushing device pushes the paper bag out of the paper discharge gap to between the first steering gear 31 and the second steering gear 32. Then, the first rocker arm 311 rotates in the opposite direction to reset to the moving passage of the paper bag, blocking behind the paper bag. Since the second rocker arm 321 is perpendicular to the first rocker arm 311, when the second rocker arm 321 rotates toward the first rocker arm 311, the first rocker arm 311 and the second rocker arm 321 clamp the side of the paper bag together, which can not only fix the paper bag, but also open the bag mouth after the paper bag is pressed. There is no need to set up a pressing plate to press the paper bag. The first rocker arm 311 and the second rocker arm 321 do not need to enter the inside of the paper bag to open the bag mouth of the paper bag, and will not occupy the moving route of the chopsticks entering the paper bag. The chopsticks can be pushed into the paper bag more smoothly.

[0071] In this embodiment, the second rocker arm 321 includes a first arm and a second arm connected to each other in an L shape. The L-shaped structure can not only clamp the paper bag, but also prevent the paper bag from slipping out from between the first rocker arm 311 and the second rocker arm 321 during the clamping process, thereby facilitating maintaining the opening state of the paper bag and allowing the chopsticks to enter the paper bag more smoothly.

[0072] The paper bag pushing device is arranged behind the paper bag storage device 61, and includes a third steering gear 33, a gear 34 and a rack 35 that are meshed and driven. The third steering gear 33 is fixed to the frame 5 and is drivingly connected to the gear 34. The rack 35 is arranged corresponding to the paper discharge gap to push the paper bag at the bottom layer in the paper bag storage device 61 out of the paper discharge gap. Preferably, the rack 35 is fixed with a flat plate of the same length as the paper bag. The flat plate is used to push the paper bag out, and the movement of the paper bag is more stable, which is conducive to aligning the bag opening with the chopstick receiving device after the paper bag is pushed out.

[0073] like Figure 3 As shown, the chopstick pushing device is arranged behind the chopstick receiving device, and includes a stepping motor 41, a synchronous belt 44 and a push rod 47. The stepping motor 41 is fixed to the frame 5 and is driven and connected to the synchronous belt 44. The synchronous belt 44 is clamped to the push rod 47, and the push rod 47 is arranged corresponding to the chopstick discharging channel.

[0074] Specifically, a driving wheel 42 and a driven wheel 43 are fixedly provided on the frame 5 , a synchronous belt 44 is wrapped around the driving wheel 42 and the driven wheel 43 , and a stepper motor 41 is connected to the driving wheel 42 to drive the driving wheel 42 to rotate.

[0075] The frame 5 is fixed with a linear guide rail 45 parallel to the push rod 47, and a moving block 46 is slidably connected to the linear guide rail 45. The moving block 46 is fixed to one end of the push rod 47 and is provided with grooves matching the synchronous belt 44 to be clamped to the synchronous belt 44. The extension direction of the push rod 47 is parallel to the chopstick outlet channel and the other end of the push rod 47 is aligned with the chopstick outlet channel.

[0076] When the synchronous belt 44 moves, it drives the moving block 46 to move on the linear guide rail 45, and then drives the push rod 47 to move back and forth on the chopstick outlet channel, pushing the pair of chopsticks at the bottom layer of the chopstick receiving device from the chopstick outlet channel into the paper bag with the bag opening opened, thereby completing the paper bag semi-packaging process of the chopsticks.

[0077] After the chopsticks are pushed into the paper bag, the first rocker arm 311 and the second rocker arm 321 release the paper bag, and the push rod 47 continues to push forward to push out the semi-packaged chopsticks together with the paper bag.

[0078] A limit switch 48 is fixedly mounted on the frame 5 . The limit switch 48 is disposed on one side of the linear guide rail 45 , corresponding to the moving block 46 , and is used to limit the moving distance of the push rod 47 when being pushed forward.

[0079] A paper bag semi-packaging method for chopsticks, using a paper bag semi-packaging device for chopsticks, comprises the following steps:

[0080] The chopstick sorting device sorts the chopstick heads and tails and conveys them to the chopstick receiving device;

[0081] The paper bag pushing device pushes a paper bag in the paper bag storage device 61 toward one side of the chopstick receiving device;

[0082] The paper bag opening device receives the paper bag pushed by the paper bag pushing device and clamps the side wall of the paper bag to open the bag mouth;

[0083] The chopstick pushing device pushes a pair of chopsticks in the chopstick receiving device into the paper bag with the bag opening opened.

[0084] By clamping the side wall of the paper bag with the paper bag opening device, the paper bag can be fixed and stabilized so that the paper bag will not move when the chopsticks are inserted, and the paper bag opening can be opened without entering the paper bag, so as not to block the chopsticks from entering the paper bag. By coordinating the action steps of the chopstick sorting device, the paper bag pushing device, the paper bag opening device and the chopstick pushing device, the paper bag semi-packaging of the chopsticks can be achieved, saving labor costs and time costs.

[0085] Furthermore, the paper bag pushing device pushes the paper bag in the paper bag storage device 61 toward the chopstick receiving device in the following manner:

[0086] The first rocker arm 311 rotates to allow the paper bag to be pushed out of the paper discharge gap to the rear passage;

[0087] The rack 35 moves toward the first rocker arm 311 to push the paper bag out of the paper discharge gap;

[0088] After the paper bag moves to between the first rocker arm 311 and the second rocker arm 321 , the rack 35 moves in the opposite direction to reset.

[0089] The first rocker arm 311 rotates to push the paper bag out of the paper outlet gap, so that the paper bag can reach the position corresponding to the chopstick receiving device from the paper outlet gap without hindering the subsequent clamping and opening action of the first rocker arm 311 and the second rocker arm 321 on the paper bag.

[0090] Furthermore, the paper bag opening device receives the paper bag pushed by the paper bag pushing device and opens the bag mouth of the paper bag in the following manner:

[0091] The first rocker arm 311 rotates in the opposite direction to press against one side of the paper bag;

[0092] The second rocker arm 321 rotates toward the first rocker arm 311 and presses against the other side of the paper box, clamping the paper bag together with the first rocker arm 311 to open the mouth of the paper bag.

[0093] Since the second rocker arm 321 is perpendicular to the first rocker arm 311, by adjusting the rotation amplitude of the second rocker arm 321, the distance between the first rocker arm 311 and the second rocker arm 321 can be expanded, making it easier for the paper bag to enter between the first rocker arm 311 and the second rocker arm 321; at the same time, the pressure applied to the paper bag by the second rocker arm 321 can be adjusted when clamping the paper bag, making it easier to open the bag mouth of paper bags of different paper materials.

[0094] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
