Description

Technical Field

[0001] This utility model relates to the field of paper cup collection technology, specifically to a curved surface printed paper cup collection mechanism. Background Technology

[0002] After the curved surface printing, the paper cups will enter the packaging process. Before packaging, a quantitative count needs to be performed to prepare for the subsequent packaging.

[0003] The common counting methods of collection mechanisms often use sensors to collect weight data or count data. Before the paper cups are taken away after being stacked and counted on the collection mechanism, an isolation mechanism is needed to isolate the subsequent paper cups. After the collection mechanism is put back into use, the isolation mechanism is removed and the next round of counting and collection begins.

[0004] The paper cup collecting mechanism designed in this scheme integrates paper cup counting and isolation through structural integration. Utility Model Content

[0006] This invention aims to at least solve the problem of simplifying and integrating the functions of paper cup quantitative collection, counting, and quantitative separation.

[0007] (II) Technical Content

[0008] This solution provides a curved surface printed paper cup collecting mechanism, achieved through the following specific technical means: including...

[0009] The receiving conveyor is connected at the front end to the discharge end of the curved surface printing machine;

[0010] The sequential release mechanism is located in the middle of the receiving and conveying frame. The sequential release mechanism includes two sets of U-shaped forks, which are symmetrical in the upper and lower parts and staggered in the front and back. The sequential release mechanism also includes a reciprocating lifting mechanism connected to the two sets of U-shaped forks. The reciprocating lifting mechanism is used to drive the two sets of U-shaped forks to move up and down at the same time. The sequential release mechanism is used to block and release paper cups one by one.

[0011] Preferred technical solution 1: The inner diameter of the U-shaped fork is smaller than the outer diameter of the convex edge of the paper cup, but not smaller than the outer wall diameter of the paper cup near the convex edge. The two sets of U-shaped forks work together to block the paper cups being conveyed from the front, and the paper cup is released backward by the two sets of U-shaped forks moving back and forth once.

[0012] Preferred technical solution 2: The receiving and conveying frame includes a bracket located below and a limiting frame located above;

[0013] The bracket consists of two sets of supporting slide rods.

[0014] Meanwhile, the limiting frame consists of two sets of limiting slide rods;

[0015] Two sets of support slide rods and two sets of limiting slide rods are parallel to each other and their front ends are fixed at the discharge port of the curved surface printing machine. The two sets of support slide rods and two sets of limiting slide rods form a channel for conveying the paper cups that are lying down. At the same time, the length of the tail end of the support slide rod is longer than that of the limiting slide rod, forming a stacking station at the tail end of the support slide rod.

[0016] Preferred technical solution 3: The reciprocating lifting mechanism includes a mounting frame located next to the receiving and conveying frame. A lifting rod slides through the mounting frame. The top and bottom crossbars of the lifting rod are fixedly connected to two sets of upper and lower U-shaped forks, respectively. The telescopic end of the top of a set of push rods fixed on the mounting frame is fixedly connected to the protruding plate on the lifting rod.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4 The curved printed paper cup 3 receiving mechanism includes a receiving conveyor frame 1 and a sequential release mechanism 2, wherein:

[0032] The receiving and conveying frame 1 includes a lower bracket 11 and an upper limiting frame 12; the bracket 11 consists of two sets of supporting slide rods 111, and the lower two sides of the lying paper cup 3 slide in contact with the two sets of supporting slide rods 111 respectively; at the same time, the limiting frame 12 consists of two sets of limiting slide rods 121, and the upper two sides of the lying paper cup 3 slide in contact with the two sets of limiting slide rods 121 respectively.

[0033] Two sets of support slide rods 111 and two sets of limiting slide rods 121 are parallel to each other and their front ends are fixed at the discharge port of the curved surface printing machine. The two sets of support slide rods 111 and two sets of limiting slide rods 121 form a channel for conveying the paper cups 3 lying down. At the same time, the length of the tail end of the support slide rod 111 is longer than that of the limiting slide rod 121, and a baffle 112 is fixed between the tail ends of the two sets of support slide rods 111, so that the tail end of the support slide rod 111 cooperates with the baffle 112 to form a stacking station 113. The released paper cups 3 move toward the tail end of the support slide rod 111 and are blocked by the baffle 112, realizing stacking at the stacking station 113.

[0034] The receiving conveyor frame 1 also includes a belt conveyor 13 located directly below the two sets of support slide bars 111. The top surface of the conveyor belt of the belt conveyor 13 is located between the two sets of support slide bars 111 and in contact with the bottom side of the paper cup 3. The paper cup 3 is moved from front to back along the channel by the top surface of the conveyor belt moving from front to back. (It is worth noting that the belt conveyor 13 mentioned in this embodiment can also be provided by the manufacturer. The frictional resistance between the conveyor belt and the paper cup 3 is greater than the sliding resistance of the paper cup 3 in the channel.)

[0035] The sequential release mechanism 2 is located in the middle of the receiving and conveying frame 1 and is used to block and release the paper cups 3 one by one. The sequential release mechanism 2 includes two sets of U-shaped forks 21 (the fork teeth on both sides of the U-shaped fork 21 are perpendicular to the axis of the paper cup 3 to ensure that the fork mouth of the U-shaped fork 21 is parallel to the cup mouth of the paper cup 3). The inner diameter of the fork mouth of the U-shaped fork 21 is smaller than the outer diameter of the outer convex cup edge of the paper cup 3 but not smaller than the outer wall diameter of the paper cup 3 near the outer convex cup edge. The two sets of U-shaped forks 21 are symmetrical in the upper and lower parts and staggered in the front and back. The staggered distance is not less than the axial thickness of the outer convex cup edge. The thickness of the U-shaped fork 21 is not greater than the distance between the outer convex cup edges of the two sets of paper cups 3 when the two sets of paper cups 3 are fully stacked. This ensures that only one paper cup 3 can be released at a time during the up and down movement of the two sets of U-shaped forks 21. At the same time, the fork teeth of the U-shaped fork 21 are at the same height or partially overlap in height.

[0036] The sequential release mechanism 2 also includes a reciprocating lifting mechanism 22 connected to the upper and lower sets of U-shaped forks 21. The reciprocating lifting mechanism 22 is used to simultaneously drive the two sets of U-shaped forks 21 to move up and down. The two sets of U-shaped forks 21 cooperate to block the paper cup 3 being conveyed from the front, and the paper cup 3 is released backward by the two sets of U-shaped forks 21 moving back and forth together once.

[0037] In one set of embodiments

[0038] Please see Figure 1 The fork teeth on both sides of the U-shaped fork 21 are located outside the two sets of support slide rods 111 and the two sets of limiting slide rods 121, so that the U-shaped fork 21 will not interfere with the movement of the support slide rods 111 and the limiting slide rods 121 when it moves up and down.

[0039] In one set of embodiments

[0040] Please see Figure 2 The reciprocating lifting mechanism 22 includes a mounting frame 221 located on the side of the receiving and conveying frame 1. A lifting rod 222 slides through the mounting frame 221. The top and bottom crossbars of the lifting rod 222 are fixed to the upper and lower sets of U-shaped forks 21 respectively. The lifting rod 222 slides and lifts on the mounting frame 221 to achieve the technical effect of driving the two sets of U-shaped forks 21 to lift synchronously.

[0041] The telescopic ends of the top of a set of push rods 223 fixed on the mounting bracket 221 are fixedly connected to the protrusions 2221 on the lifting rod 222. The telescopic movement of the push rods 223 is used to control the lifting and lowering of the lifting rod 222. The number of telescopic movements of the push rods 223 is recorded by connecting a linear encoder (such as a grating ruler) or a rotary encoder (which converts motion through a lead screw) to the push rods 223. The encoder converts the displacement into a pulse signal, and the counter accumulates the number of pulses. The numerical feedback display of the encoder count needs to be displayed through a matching display device. It is worth noting that the push rods 223, the specific model of the encoder, and its matching power supply and control switch mentioned in this embodiment can also be provided by the manufacturer. The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. Furthermore, the telescopic range of the push rods 223 is obtained through actual testing.

[0042] During use, this solution requires daily maintenance of each component according to the established maintenance plan to ensure its working condition.

[0043] In practical use:

[0044] Step 1: In the initial state, push rod 223 is in the retracted state. At this time, the upper set of U-shaped forks 21 extends to the middle and lower part of both sides of the channel, and the lower set of U-shaped forks 21 moves away from the channel. At this time, the paper cups driven by the conveyor belt are blocked by the upper U-shaped forks 21, and the front wall of the upper U-shaped forks 21 contacts the outer convex edge of the nearby paper cup.

[0045] Step two, the push rod 223 extends, causing the upper U-shaped fork 21 to move to the middle of both sides of the channel, while the lower U-shaped fork 21 moves up and extends to the middle of both sides of the channel. At this time, the upper and lower U-shaped forks 21 cooperate to be located on the front and back sides of the outer rim of the paper cup on the last side that is blocked, thereby clamping the paper cup. At this time, the multiple paper cups in front are changed from being blocked by the upper U-shaped fork 21 to being blocked by the lower U-shaped fork 21.

[0046] Step 3: Push rod 223 continues to extend, causing the bottom of the upper U-shaped fork 21 to move away from the channel, and the top of the lower U-shaped fork 21 to move to the middle and upper part of both sides of the channel, releasing the obstruction of the last paper cup on the blocked side. The paper cup is released and can continue to move backward along the channel with the conveyor belt to the stacking station 113, while the remaining paper cups in front are still blocked.

[0047] Step four, push rod 223 begins to retract and reset, causing the upper U-shaped fork 21 to move down and the lower U-shaped fork 21 to move down, so that the paper cup that was blocking is once again in contact with the upper U-shaped fork 21 (i.e., the state in step one).
