DETAILED DESCRIPTION

[0048] The present invention is further described in detail below in conjunction with the accompanying drawings of the specification. The accompanying drawings schematically and simply show the structure of the marker pen box packaging system and the marker pen box packaging method.

[0049] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0050] The embodiment of the present invention provides a marker pen box packaging system, see Figure 1 and Figure 2 As shown, it includes a work platform 1, and the work platform 1 has at least one loading station 1a, at least one unloading station 1b, and multiple writing stations 1c located between the loading station 1a and the unloading station 1b. A track assembly 2 is arranged on the work platform 1, and the track assembly 2 includes a track 21 and a trolley 22. The track 21 extends along the line connecting the writing stations 1c, and there are multiple trolleys 22, and the multiple trolleys 22 can move along the track 21 and pass through at least one loading station 1a, multiple writing stations 1c, and at least one unloading station 1b in sequence.

[0051] The marker pen box packaging system also includes a pen box assembly 3, which is composed of a plurality of pen boxes 31 and a pen box driving member 32. The pen box driving member 32 can drive the pen box 31 to move, drive the blank pen box 31 to the trolley 22 at the loading station 1a, and drive the pen box 31 filled with markers to leave the trolley 22 at the unloading station 1b. The pen box 31 has a plurality of pen slots 311, and the pen slots 311 are used to load markers. The pen box 31 is located on the trolley 22 and moves with the trolley 22, so as to pass through at least one loading station 1a, a plurality of pen dropping stations 1c, and at least one unloading station 1b in sequence.

[0052] Combination Figure 1 and Figure 3 As shown, the marker pen box packaging system further includes a pen drop assembly 6, which includes a plurality of pen drop buckets 61 for loading bulk marker pens, and the plurality of pen drop buckets 61 are arranged along the connecting line of the plurality of pen drop stations 1c. The outlets of the pen drop buckets 61 correspond to different positions of the pen drop stations 1c, and when the pen box 31 moves to different pen drop stations 1c, the outlets of the plurality of pen drop buckets 61 correspond to different positions of the pen slots 311 on the pen box 31.

[0053] The marker pen box packaging system further includes a control unit 10, which is in communication with the track assembly 2, the pen box assembly 3 and the pen drop assembly 6, and controls the actions of the track assembly 2, the pen box assembly 3 and the pen drop assembly 6. The control unit 10 is a computer or a control cabinet.

[0054] According to the marker pen box packaging system provided in this embodiment, the pen box driving member 32 drives the blank pen box 31 to the trolley 22 located at the loading station 1a, and the trolley 22 drives the pen box 31 to move along the track 21, and passes through multiple pen-dropping stations 1c in sequence before arriving at the unloading station 1b. At each pen-dropping station 1c, the pen-dropping assembly 6 drives a marker pen in the pen-dropping bucket 61 to drop into one of the pen slots 311 of the pen box 31 until the pen slot 311 of the pen box 31 is filled with marker pens. When the pen box 31 filled with marker pens arrives at the unloading station 1b, the pen box driving member 32 drives the pen box 31 filled with marker pens to move and detach from the trolley 22. The marker pen box packaging system can realize the automatic box packaging of marker pens, reduce manual participation, greatly reduce labor costs, and also reduce the error rate caused by manual labor. The marker pen box packaging system adopts fully automated and mechanized operations, which greatly improves the efficiency of marker pen box packaging. It has been verified through experiments that, using the marker pen boxing and packaging system in this embodiment, each pen-dropping assembly 6 can box 6-20 marker pens per minute. With the cooperation of multiple pen-dropping assemblies 6, each marker pen boxing and packaging system can box hundreds to nearly a thousand marker pens per minute.

[0055] In this embodiment, combined with Figure 1 and Figure 4 As shown, the track 21 is a circular track 21, and at least one loading station 1a, a plurality of writing stations 1c and at least one unloading station 1b are arranged in a circular shape. The track assembly 2 also includes a circular chain 23 (the circular chain 23 has many lines, which are only shown in FIG. Figure 4 and Figure 5The schematic diagram shows the positional relationship between the circular chain 23 and the trolley 22 and the track motor 24 that drives the circular chain 23 to move. The circular chain 23 is located in the inner circle of the circular track 21. The side end of the trolley 22 is fixed to the chain link of the circular chain 23. When the circular chain 23 moves, the trolley 22 moves accordingly. The trolley 22 starts to move from the loading station 1a, and driven by the circular chain 23, it passes through multiple writing stations 1c in sequence and arrives at the unloading station 1b, and then moves to the loading station 1a again, and repeats the above path. The track 21 is set to be circular and the circular chain 23 is set, so that the circular movement of the trolley 22 can be realized. The trolley 22 can automatically reset to the loading station 1a and perform a circular movement, which further improves the automation of box packaging and improves the efficiency of box packaging. The trolley 22 reciprocates and automatically resets to the initial state, which can simplify the operation procedure of the trolley 22 and facilitate the efficient operation of the trolley 22.

[0056] Preferably, the bottom of the trolley 22 is provided with pulleys 221, and there are four pulleys 221 arranged in pairs on both sides of the track 21. The provision of the pulleys 221 can reduce the friction between the trolley 22 and the track 21, and the trolley 22 can move on the track 21 flexibly, and the trolley 22 can also be limited to move on the track 21 to prevent the trolley 22 from slipping off the track 21.

[0057] The pen case driving member 32 includes a pen case slot seat 41, a loading push rod 42 and a loading motor 43. The pen case slot seat 41 is close to the loading station 1a and is used to store blank pen cases 31. The loading motor 43 is used to drive the loading push rod 42 to extend and retract. The loading motor 43 drives the loading push rod 42 to extend and push the blank pen case 31 located at the pen case slot seat 41 onto the trolley 22 that moves to the loading station 1a. In this way, the automatic loading of the blank pen case 31 can be realized, manual work can be reduced, and the loading of the blank pen case 31 can be automatically performed. The pen case driving member 32 has a simple structure and precise action.

[0058] The pen box driving member 32 also includes a feeding push rod 51 and a feeding motor (blocked in the figure, the feeding motor is a motor of simple structure, and the marking is omitted in the figure). Connected to the feeding station 1b, the feeding motor drives the feeding push rod 51 to extend and retract. The feeding motor drives the feeding push rod 51 to extend, push the pen box 31 full of markers on the trolley 22 moved to the feeding station 1b to the top, and transport the pen box 31 full of markers away. With such a setting, the pen box 31 full of markers can be automatically dropped, reducing manual work, and automatically unloading the pen box 31 full of markers. The pen box driving member 32 has a simple structure and precise action.

[0059] The pen drop assembly 6 also includes a pen outlet bin 71, the inlet of the pen outlet bin 71 is connected to the outlet of the pen drop bucket 61, the outlet of the pen outlet bin 71 corresponds to the pen drop station 1c, and the pen outlet bin 71 includes an inclined section 71a and a vertical section 71b, the inclined section 71a is close to the pen drop bucket 61 and the inner bottom is inclined, and the vertical section 71b is close to the pen drop station 1c and the inner wall is vertical. The marker pen can fall from the pen drop bucket 61 into the pen outlet bin 71, then tilt under the inclined inclined section 71a, and then enter the vertical section 71b to become a vertical state, and fall in a vertical state. With this arrangement, the marker pen falls vertically into the pen slot 311, which can increase the accuracy of the marker pen falling into the pen slot 311.

[0060] In particular, see Figure 3 As shown, a pen-dropping slide bar 72 is slidably provided at the outlet of the pen outlet bin 71. The interior of the pen-dropping slide bar 72 is hollow and has openings at both ends. The pen-dropping slide bar 72 is vertically provided, and an electromagnetic valve 62 is provided at the bottom of the pen-dropping slide bar 72. The top opening of the pen-dropping slide bar 72 is connected to the bottom of the inclined section 71a, and the outlet corresponds to the pen-dropping station 1c. One end of the pen-dropping slide bar 72 is connected to the cylinder 73, and the telescopic rod of the cylinder 73 is telescopic in the same direction as the length of the pen-dropping slide bar 72. When the cylinder 73 works, the telescopic rod drives the pen-dropping slide bar 72 to move downward, thereby driving the marker pen that falls into the pen-dropping slide bar 72 to fall, and the pen-dropping slide bar 72 moves into the pen slot 311 of the pen box 31. The electromagnetic valve 62 opens the bottom of the pen-dropping slide bar 72, so that the marker pen falls vertically into the pen slot 311. This arrangement reduces the travel of the marker pen from the pen-dropping slide bar 72 to the pen slot 311, further allowing the marker pen to accurately drop into the pen slot 311. More preferably, the pen-dropping slide bar 72 can extend into the pen slot 311 of the pen case 31 under the drive of the cylinder 73, and the pen-dropping slide bar 72 moves into the pen slot 311 to correct the position of the pen slot 311 and the marker pen, further ensuring the accurate drop of the marker pen.

[0061] The pen drop assembly 6 also includes a pen drop conveyor belt 81 and a transmission motor 82 for driving the pen drop conveyor belt 81. The outlet of the pen drop bucket 61 is horizontal and located directly above the pen drop conveyor belt 81. The markers in the pen drop bucket 61 are placed horizontally, and when they reach the outlet of the pen drop bucket 61, they are received by the pen drop conveyor belt 81. The transmission motor 82 works to drive the pen drop conveyor belt 81 to move, and the markers are driven to fall into the pen outlet bin 71. The markers are transmitted by the pen drop conveyor belt 81, and the accuracy of the horizontal transmission of the markers is improved.

[0062] There is a pusher bin 84 between the pen drop conveyor 81 and the pen outlet bin 71, and a pusher motor 85 is provided on the pusher bin 84, and the pusher motor 85 is configured to be able to extend to push the marker pen dropped into the pusher bin 84 into the pen outlet bin 71. By providing the pusher motor 85 to push the marker pen into the pen outlet bin 71, the marker pen can be automatically dropped into the pen outlet bin 71 one by one, so that the marker pen can be orderly moved and the marker pen can be prevented from being blocked. At the same time, it is also convenient to detect the status of the marker pen in each link, and to detect and feedback the status of the marker pen in time.

[0063] In particular, a pen drop sensor 83 is provided at the exit of the pen drop bucket 61 and / or a pen outlet sensor 74 is provided at the exit of the pen outlet bin 71, and the pen drop sensor 83 and / or the pen outlet sensor 74 are connected to the control unit 10 for communication. In the present embodiment, the pen drop sensor 83 is provided at the exit of the pen drop bucket 61 and detects the presence of a marker pen at the pen drop opening, and the pen outlet sensor 74 is provided at the bottom of the pen drop slide bar 72 and detects the presence of a marker pen in the pen drop slide bar 72. In the present embodiment, the pen drop sensor 83 is provided at a position close to the push bin 84, so that the presence of a marker pen in the push bin 84 can be detected. If the presence of a marker pen is incorrect in a specific stroke, an alarm will be issued in time and the action will be suspended. In addition, a pen outlet confirmation sensor 86 is also provided below the pen outlet sensor 74 to detect the presence of a marker pen at the position below the slide bar 72.

[0064] Combination Figure 1 and Figure 3 As shown, at least one writing station 1c on the working platform 1 is provided with a retractable correction block 9, and the extension and retraction of the correction block 9 is driven by a correction motor 91, and the correction motor 91 is in communication with the control unit 10. A correction seat 93 is provided on the trolley 22, which is used to abut against the extended correction block 9. When the trolley 22 drives the pen box 31 to move to a certain writing station 1c, the correction motor 91 drives the correction block 9 to extend for N seconds, and the correction block 9 abuts against the correction seat 93, and the trolley 22 is confined to the writing station 1c, thereby preventing the trolley 22 from sliding incorrectly and improving the stop accuracy of the trolley 22. Of course, in other embodiments of the present invention, it is sufficient as long as a correction block 9 is provided at at least one writing station 1c.

[0065] Corresponding to the correction block 9, a correction sensor 92 is provided at the writing station 1c on the working platform 1 (see Figure 2 ), the correction sensor 92 is connected in communication with the control unit 10 to detect whether the trolley 22 stops at the correct position each time it stops.

[0066] In particular, in this embodiment, the sum of the writing station 1c, the loading station 1a, and the unloading station 1b is not less than the number of the trolleys 22, and the number of the writing stations 1c is not less than the number of the pen slots 311 of the pen box 31. This ensures that the trolley 22 can move along the track 21 in an orderly manner, and also ensures that the pen slots 311 of the pen box 31 can be filled.

[0067] Based on this, this embodiment also provides a marker pen box packaging method, see Figure 6 As shown, the following steps are included:

[0068] Step 1: The loading motor 43 drives the loading push rod 42 to extend, and the loading push rod 42 pushes the blank pencil case 31 onto the trolley 22 located at the loading station 1a;

[0069] Step 2: The trolley 22 is driven by the ring chain 23 and moves along the track 21, passing through a plurality of writing stations 1c in sequence;

[0070] Step 3: The trolley 22 moves to the adjacent writing station 1c, the correction block 9 extends out and abuts against the trolley 22, and the correction sensor 92 senses whether the trolley 22 has stopped at the writing station 1c;

[0071] Step 4: The conveying motor 82 drives the pen-dropping conveyor belt 81 to move, so that a marker pen in the pen-dropping bucket 61 falls into the pen-discharging bin 71 along with the pen-dropping conveyor belt 81, and the pen-discharging sensor 74 detects whether there is a marker pen on the pen-dropping conveyor belt 81, thereby detecting whether the marker pen falls into the pen-discharging bin 71;

[0072] Step 5: The marker pen passes through the inclined section 71a and the vertical section 71b in sequence, and automatically enters the pen-dropping slide bar 72 in a vertical state. The cylinder 73 drives the pen-dropping slide bar 72 to move downward to one of the pen slots 311 of the pen box 31. The solenoid valve 62 opens the bottom of the pen-dropping slide bar 72, and the marker pen falls into the pen slot 311. The discharge sensor detects whether there is a marker pen in the pen-dropping slide bar 72, thereby detecting whether the marker pen falls into the pen slot 311.

[0073] Repeat the above steps 3-5 until the pen slot in the pen box 31 is filled with markers;

[0074] Step 6: The trolley 22 moves to the unloading station 1b, and the unloading motor drives the unloading push rod 51 to extend, and the unloading push rod 51 pushes out the pen box 31 filled with markers.

[0075] In particular, in this embodiment, the motor or the cylinder as the driving element can be easily replaced.
