Description

Technical Field

[0001] The present application relates to the technical field of paper container manufacturing, and in particular to a paper cup machine unloading, stacking and collecting device and paper cup production equipment. Background Art

[0002] Paper tableware is becoming a fashion trend and is now widely used in business, aviation, mid- to high-end fast food restaurants and other fields. According to an industry data report provided by Betzers Consulting, the global market size of disposable paper cups and paper lids reached 22.723 billion yuan in 2022, and it is predicted that by 2028, the global market size will reach 30.754 billion. The market demand for disposable paper cups is constantly increasing, which puts forward new requirements for efficient and fast collection of paper cups.

[0003] After the paper cups on the market are produced by the forming machine, they need to be collected and packaged. In order to achieve efficient and fast packaging of paper cups, the paper cups are generally transported to the packaging table through a conveying pipe by wind power, and the operators then quantitatively package the collected paper cups. Therefore, the quality and shape of the paper cups are continuously controlled during the paper cup feeding process. The cups are easily stuck during the transportation process, resulting in low paper cup feeding and collection efficiency. In addition, the collected paper cups are relatively scattered, requiring manual participation in sorting and quantitative packaging, and high production costs. Summary of the invention

[0004] Based on this, it is necessary to provide a paper cup machine unloading, stacking and collecting device and paper cup production equipment that can improve the paper cup unloading speed and collection efficiency.

[0005] In order to solve the above technical problems, this application provides the following technical solutions:

[0007] A conveying carrier, on which a plurality of cup placement slots for accommodating paper cups are arranged at intervals and penetrated, and the conveying carrier is configured to drive the cup placement slots to flow among a loading area, a correction area, a waste cup collection area and a qualified cup collection area in sequence;

[0008] A correction component, disposed in the correction area, for adjusting the position of the paper cup in the cup placement groove;

[0009] A waste cup unloading assembly, disposed in the waste cup collecting area, for moving the waste cup out of the conveying carrier; and

[0010] The qualified cup unloading assembly includes a cup storage structure and a cup transfer assembly arranged in the qualified cup collection area. The cup storage structure is used to transfer the qualified cups in the cup placing groove and stack a specified number of qualified cup tubes into cup tubes. The cup transfer assembly is used to transfer the stacked cup tubes to the cup tube storage area.

[0011] It can be understood that the cup placing slot is driven by the conveying carrier to flow among the loading area, the correction area, the waste cup collection area and the qualified cup collection area in sequence, so that a single paper cup is placed in the cup placing slot in the loading area, and the paper cup in the cup placing slot is adjusted to a specified posture under the action of the correction component. Then, the waste product is moved out of the conveying carrier by the waste cup unloading component, and the qualified cups are stacked one by one at the cup storage structure to form a cup tube. After the specified number of cups are stacked, the cup tube is sent to the cup tube storage area by the qualified cup unloading component, thereby realizing the efficient flow of the fully automated paper cup unloading, stacking and collection process. By adjusting the posture of the paper cup, the cup jamming phenomenon is avoided, the production efficiency is improved, the waste products and qualified products are collected separately, and the product quality is improved.

[0012] In one embodiment, the cup transfer assembly includes a cup transfer member and a collecting slide, one end of the collecting slide is arranged close to the cup transfer member, and the other end is connected to the cup tube storage area. The cup transfer member transfers the cup tube to the collecting slide, and the cup tube slides to the cup tube storage area through the collecting slide.

[0013] It is understandable that by providing a cup transfer member to move the cup tube into the collecting slide, the cup tube slides to the cup tube storage area through the collecting slide, and the slide is used to realize the long-distance transmission of the cup tube, while also ensuring the integrity of the cup tube.

[0014] In one embodiment, the cup moving member includes a cup gripper for grabbing the cup tube, a translation structure drivenly connected to the cup gripper and used to drive the cup gripper to move in a horizontal direction, and a lifting structure drivenly connected to the translation structure and used to drive the translation structure to move in a vertical direction.

[0015] It can be understood that by arranging the translation structure and the lifting structure to cooperate with driving the cup grabbing gripper to grab the cup tube, and being able to move in the vertical direction and the horizontal direction to transfer the cup tube to the cup tube storage area, automatic collection of the cup tube is achieved.

[0016] In one of the embodiments, the cup gripper includes a gripper frame fixed on the translation structure and a pair of cup gripper clamps symmetrically arranged on the gripper frame, and the cup gripper clamps include a first cylinder arranged in a vertical direction, a second cylinder connected to the output shaft of the first cylinder and arranged horizontally, and clamping teeth connected to the output shaft of the first cylinder.

[0017] It can be understood that by arranging the first cylinder to drive the clamping teeth to move up and down, the clamping teeth can clamp the cup tube at a suitable position, and the stroke of the lifting mechanism can also be effectively reduced.

[0018] In one embodiment, the cup storage structure includes a cup-lifting member disposed below the conveying carrier and a cup-storing member disposed above the conveying carrier, and the cup-lifting member is used to push and stack the qualified cups in sequence into the cup-storing member.

[0019] It can be understood that by pushing the paper cups from bottom to top into the cup storage member through the cup pushing member so as to be stacked to form a specified number of cup tubes, stacking and storage of paper cups is achieved, and the stacking and collection efficiency of paper cups is effectively improved.

[0020] In one of the embodiments, the cup storage member includes a guide ring and an elastic clamping plate arranged on the upper surface of the guide ring, and the elastic clamping plate is configured to be stretched open by the large diameter end of the qualified cup and then clamped at the small diameter end of the qualified cup.

[0021] It can be understood that by providing a guide ring to guide the lifted paper cup to move upward to open the elastic clamp, after the lifting force disappears, the elastic clamp is clamped on the small diameter end to prevent the paper cup from falling, and at the same time it is convenient for the subsequent paper cup to be sleeved on the outside of the previous paper cup, thereby achieving the stacking of paper cups to form a cup tube.

[0022] In one embodiment, a pair of elastic clamps are symmetrically arranged, and the elastic clamps include a clamping plate and an elastic member radially arranged along the guide ring, one end of the elastic member is connected to the guide ring, and the other end is connected to the clamping plate. When the elastic member is in a normal state, at least a portion of the clamping plate is held against the guide ring.

[0023] It can be understood that by providing an elastic member to hold the clamping plate in the guide ring, when the paper cup is lifted to the elastic clamping plate, the clamping plate is pushed to both sides to compress the elastic member, so that the two clamping plates are held against the cup wall, thereby realizing the collection of paper cups, and after repeated actions, multiple paper cups are stacked into a cup tube.

[0024] In one embodiment, the correction component is disposed above the conveying carrier, and the correction component includes a clapper and a power member that drives the clapper to move closer to or away from the cup placing groove in a vertical direction.

[0025] It can be understood that by providing a power member to drive the clapper to move toward the cup placing groove, paper cups of different shapes in the cup placing groove can be pressed into the cup placing groove, so that all paper cups can maintain the same posture during the subsequent collection process, and the paper cups can be stacked into cup tubes.

[0026] In one embodiment, the waste cup unloading assembly includes a cup blowing member disposed below the conveying carrier and an inverted U-shaped collecting tube disposed above the conveying carrier, and the cup blowing member is used to blow the waste cup into and collect it into the U-shaped collecting tube.

[0027] It can be understood that the paper cups pressed into the cup placing groove are blown upward by the cup blowing member so as to move from one end of the U-shaped collecting tube to the other end. Under the action of gravity, the paper cups are stacked and collected into waste cup tubes, which is convenient for subsequent storage and processing of the waste cups.

[0028] In one embodiment, the conveying carrier is a five-hole disk that can rotate around the center of a circle, and a plurality of the cup placement grooves are arranged at intervals along the circumference of the five-hole disk.

[0029] It can be understood that by providing a rotatable five-hole disk to drive the cup placement groove to rotate along the center of the five-hole disk, the loading area, correction area, waste cup collection area and qualified cup collection area can be arranged centrally, thereby reducing the volume of the entire mechanism.

[0030] In one embodiment, the cup tube storage area includes a storage table, a cup receiving assembly arranged near the edge of the storage table, and a cup pushing assembly arranged at the edge of the storage table, the cup receiving assembly is docked with the other end of the collection slide, and is configured to be switchable between a first docking state with the collection slide at an inclined angle and a second docking state flush with the upper surface of the storage table.

[0031] It can be understood that by setting up the collecting slide, it is convenient for the cup tube to slide from the cup transferring assembly to the storage platform. At the same time, the cup receiving assembly is arranged to dock with the collecting slide at an inclined angle in a first docking state to avoid excessive collision of the cup tube during sliding. After the cup receiving assembly receives the cup tube, it is in a second docking state flush with the upper surface of the storage table and is pushed into the storage table by the action of the cup pushing assembly, which facilitates the storage of the cup tube on the storage table and avoids its retention at the exit end of the collecting slide, thereby causing other cup tubes to be unable to fall or fall outside the storage platform.

[0032] This application also provides the following technical solutions:

[0033] A paper cup production device comprises the paper cup machine unloading, stacking and collecting device as described above.

[0034] It can be understood that by providing the above-mentioned paper cup machine unloading, stacking and collecting device, the full automation of the paper cup production process is achieved, thereby improving the production efficiency and product quality.

[0036] It can be understood that the formed paper cup is moved to the top of the cup placing groove by the paper cup mold, and the paper cup is blown into the cup placing groove by the blow mold member arranged in the paper cup mold, which shortens the conveying path of the paper cup and is conducive to improving production efficiency. The paper cups are conveyed one by one, avoiding the cup jamming phenomenon during the paper cup conveying process.

[0037] Compared with the prior art, the paper cup machine unloading, stacking and collecting device drives the cup placing groove to flow among the loading area, the correction area, the waste cup collection area and the qualified cup collection area in sequence through the conveying carrier, so that a single paper cup is placed in the cup placing groove in the loading area, and the paper cup in the cup placing groove is adjusted to a specified posture under the action of the correction component, and then the waste is moved out of the conveying carrier by the waste cup unloading component, and the qualified cups are stacked one by one at the cup storage structure to form a cup tube, and after the specified number of cups are stacked, the cup tube is sent to the cup tube storage area by the qualified cup unloading component, thereby realizing the efficient flow of the fully automated paper cup unloading, stacking and collection process, avoiding the cup jamming phenomenon by adjusting the posture of the paper cup, improving the production efficiency, collecting the waste and qualified products separately, and improving the product quality.

[0058] See also Figure 1 to Figure 2 The present application provides a paper cup machine blanking, stacking and collecting device 100, which is used in the finished paper cup blanking and collecting link in the paper cup production process to realize the stacking and collection of single paper cups to form a specified number of cup tubes.

[0059] Specifically, the paper cup machine unloading, stacking and collecting device includes a conveying carrier 120, a correction component 130, a waste cup unloading component 140 and a qualified cup unloading component 150. The conveying carrier 120 is used to receive formed paper cups in the loading area, and convey a single paper cup to the correction area, the waste cup collection area and the qualified cup collection area in sequence. After the posture is corrected by the correction component 130, the paper cup is stacked and collected into cup tubes by the waste cup unloading component 140 or the qualified cup unloading component 150, thereby improving the unloading, stacking and collection efficiency of the paper cups.

[0060] In this embodiment, the paper cup machine unloading, stacking and collecting device also includes a loading assembly 110 arranged in the loading area and located above the conveying carrier 120. The loading assembly 110 includes a ten-hole plate 112, a plurality of paper cup molds 114 arranged at intervals along the circumference of the ten-hole plate 112, and a blow mold part arranged in the paper cup mold 114. The ten-hole plate 112 is configured to rotate so that the paper cup mold 114 can dock with the cup placement groove 124, and the paper cup is blown into the cup placement groove under the action of the blow mold part. The loading area overlaps with the unloading area of ​​the paper cup forming machine, that is, the loading assembly 110 in this application can also be a unloading assembly on the paper cup forming machine. After the paper cups on the paper cup forming machine are formed on the paper cup mold 114, they are directly unloaded to the conveying carrier 120 through the blow mold part. The ten-hole disk 112 is a disk that can rotate around the center of a circle. Ten paper cup molds 114 are arranged on the ten-hole disk 112 at equal intervals along the circumferential direction. Under the rotation of the ten-hole disk 112, when one of the paper cup molds 114 moves to the top of the conveying carrier 120, the paper cup on the paper cup mold 114 is blown down to the conveying carrier 120 by the blow mold part, thereby completing the loading process of the paper cup machine unloading stacking collection device 100. Among them, the blow mold part includes a blowing nozzle arranged on the paper cup mold 114 and a gas generating part connected to the blowing nozzle. Of course, in order to facilitate the separation of the paper cup from the paper cup mold 114, a demolding structure can also be provided to assist the demolding of the paper cup, such as a push gripper. The paper cup forming machine is a prior art and will not be described in detail here.

[0061] A plurality of cup placement grooves 124 for accommodating paper cups are arranged at intervals on the conveying carrier 120, and the conveying carrier 120 is configured to drive the cup placement grooves 124 to flow between the loading area, the correction area, the waste cup collection area and the qualified cup collection area in sequence. In this embodiment, the conveying carrier 120 is a five-hole disk 122 that can rotate around the center of a circle, and a plurality of cup placement grooves 124 are arranged at intervals along the circumference of the five-hole disk 122. The center of the five-hole disk 122 is connected to a rotating shaft, which is connected to a motor. There are five cup placement grooves 124, and the five cup placement grooves 124 are arranged at equal intervals along the circumference of the five-hole disk 122. The five-hole disk 122 is driven by a motor to rotate, so that the five cup placement grooves 124 rotate around the center of the five-hole disk 122, and the loading area, the correction area, the waste cup collection area and the qualified cup collection area are arranged in sequence along the rotation direction. Such an arrangement can effectively reduce the space required for the conveying carrier 120, which is conducive to centralized layout. In other embodiments, the conveying carrier 120 is also a conveying line, such as an elliptical turning line, etc., as long as it can realize the circulation of paper cups, and no specific limitation is made here.

[0062] It should be noted that the paper cup includes a large diameter end and a small diameter end. Most of the existing paper cups have a trend of gradually decreasing diameter from the cup mouth to the cup bottom, that is, the cup mouth is the large diameter end and the cup bottom is the small diameter end. The cup placement groove 124 is mostly a columnar hole. In order to prevent the paper cup from falling from the cup placement groove 124, the diameter of the cup placement groove 124 is slightly smaller than the large diameter end of the paper cup. Therefore, when the paper cup falls into the cup placement groove 124, the axis of the paper cup cannot be consistent with the axis of the cup placement groove 124. In order to facilitate the collection and stacking of the paper cups, the position of the paper cup needs to be adjusted.

[0063] Please refer to Figure 3 , the correction component 130 is arranged in the correction area to adjust the position of the paper cup in the cup placement groove 124. In this embodiment, the correction component 130 is arranged above the five-hole plate 122, and the correction component 130 includes a clapper 132 and a power member 134 that drives the clapper 132 to approach or move away from the cup placement groove 124 in the vertical direction. The power member 134 is a cylinder, and the cylinder is suspended above the five-hole plate 122 through a fixed rod 136. The output shaft of the cylinder is arranged along the axial direction of the cup placement groove 124. The clapper 132 is a circular plate, which is fixedly connected to the cylinder output shaft and arranged parallel to the five-hole plate 122. The clapper 132 is driven by the cylinder to move toward the five-hole plate 122 to press the paper cup part protruding from the upper surface of the cup placement groove 124 in the cup placement groove 124 into the cup placement groove 124, so that the position of the paper cup after passing through the correction area remains consistent, so as to facilitate subsequent collection and stacking.

[0064] Please refer to Figure 4, the waste cup unloading component 140 is arranged in the waste cup collection area to move the waste cups out of the conveying carrier 120. In the conventional paper production process, there is basically no problem of waste cups, but the paper cups formed after the emergency stop button of the paper cup forming machine is pressed are basically waste cups. Therefore, the waste cup unloading component 140 does not work in the general production process, but is manually or automatically started to work for a period of time after the emergency stop button of the paper cup forming machine is pressed, so as to collect the waste cups produced after the emergency stop is pressed. Of course, in some high-demand paper cup production processes, when there are strict requirements on the quality of paper cups, the paper cups can also be inspected by arranging detection parts in the waste cup collection area. The detection parts can be image detection systems, etc., which detect paper cups through paper cup images, so that waste cups and qualified cups can be collected separately.

[0065] In this embodiment, the waste cup unloading assembly 140 includes a cup blowing member 142 disposed below the five-hole plate 122 and an inverted U-shaped collection tube disposed above the five-hole plate 122. The cup blowing member 142 is used to blow the waste cup into and collect it in the U-shaped collection tube. The cup blowing member 142 is similar in structure to the film blowing member, except that the cup blowing member 142 is disposed on the five-hole plate 122, and blows air from bottom to top to blow the waste cup into the U-shaped collection tube. In addition, in order to ensure that the paper cup enters the U-shaped collection tube, a lifting cylinder is provided to push the cup blowing member 142 to first push the paper cup into the U-shaped collection tube, and then the paper cup is blown into the U-shaped collection tube through the cup blowing member 142. In addition, the inlet end of the U-shaped collection tube can also be configured as a trumpet-shaped guide tube 146 to facilitate the entry of the paper cup. The U-shaped collecting tube is a mesh tube 144, and the other end of the U-shaped collecting tube is a collecting end of a longer straight section, and a closing plate is provided at the end. The collecting end is connected to the trumpet-shaped guide tube 146 through a 180° curved tube section, so that the paper cups enter the U-shaped collecting tube from the inlet end and flip 180° upside down in the collecting end, and a side door 148 is provided on the side wall of the collecting end to facilitate the removal of the waste cups after a certain number of stacking. Of course, in other embodiments, the closing plate can also be set as an openable closing door for the removal of the waste paper cup tube.

[0066] The qualified cup unloading component 150 includes a cup storage structure and a cup transfer component 156 arranged in the qualified cup collection area. The cup storage structure is used to move the qualified cups in the cup placement groove 124 out and stack a specified number of qualified cup tubes into cup tubes. The cup transfer component 156 is used to send the stacked cup tubes to the cup tube storage area 160.

[0067] Please refer to Figures 5 and 6In this embodiment, the cup storage structure includes a cup lifting member 152 disposed below the five-hole plate 122 and a cup storage member 154 disposed above the five-hole plate 122. The cup lifting member 152 is used to push qualified cups to be stacked in the cup storage member 154 in sequence. The cup lifting member 152 includes a push rod 1524 arranged along the axis direction of the cup placement groove 124, a head 1522 fixed to the end of the push rod 1524, and a driving member 1528 connected to the other end of the push rod 1524. The driving member 1528 is a crank structure driven by a motor. The push rod 1524 is inserted into the sliding bearing seat 1526, and reciprocates along the axis of the push rod 1524 under the drive of the driving member 1528 to lift the paper cups to the cup storage member 154 for storage. Of course, in other embodiments, the driving member 1528 may also be a cylinder or other forms of driving member 1528, as long as it can lift the paper cup to the cup storage member 154 for storage, and no specific limitation is made here.

[0068] Please refer to Figure 7 In this embodiment, the cup storage member 154 includes a guide ring 1541 and an elastic clamping plate arranged on the upper surface of the guide ring 1541. The elastic clamping plate is configured to be clamped at the small diameter end of the qualified cup after being stretched open by the large diameter end of the qualified cup. Two elastic clamping plates are provided, and the two elastic clamping plates are symmetrically arranged on the top of the guide ring 1541. The elastic clamping plate includes a fixing block 1542 arranged near the outer edge of the guide ring 1541, an elastic member 1544 arranged on the fixing block 1542, and a clamping plate 1543 arranged at the end of the elastic member 1544. The elastic member 1544 includes a connecting rod penetrating the fixing block 1542 and a spring sleeved on the connecting rod. The spring is connected to the fixing block 1542 and the clamping plate 1543. The spring is in an uncompressed state under normal conditions. The clamping plate 1543 is held at a position close to the inner ring of the guide ring 1541, and part of the clamping plate 1543 extends into the inner ring of the guide ring 1541. The clamping plate 1543 is an arc-shaped plate, and the clamping surface of the arc-shaped plate is an inclined surface, and gradually approaches the axis of the guide ring 1541 from the end close to the upper surface of the guide ring 1541 to the end away from the guide ring 1541. When the paper cup is lifted to the clamping plate 1543 by the cup-lifting member 152, the large diameter end of the paper cup moves along the bottom of the inclined surface of the guide ring 1541, and the cup-lifting member 152 drives the paper cup to continue to move upward, and the large diameter end of the paper cup opens the clamping plate 1543 to both sides, and the spring is compressed. When the large diameter end of the paper cup extends from the top of the inclined surface, as the paper cup continues to move upward, the diameter of the paper cup against which the top of the inclined surface abuts gradually decreases, so that the clamping plate 1543 continues to abut against the wall of the paper cup under the action of the spring. When the paper cup stops moving upward, the spring abuts the clamping plate 1543 against the small diameter end of the paper cup, thereby preventing the paper cup from falling. This process is repeated to achieve stacking and collection of paper cups. Preferably, the slope of the inclined surface of the clamping plate 1543 is consistent with the slope of the wall of the paper cup.

[0069] The guide ring 1541 is fixed on the fixed column 1545 through a connecting structure so that the guide ring 1541 is located above the five-hole disk 122. The connecting structure includes a mounting plate 1546 fixed on the fixed column 1545 and an adjusting plate 1547 connected between the mounting plate 1546 and the guide ring 1541. The position of the guide ring 1541 is adjusted by adjusting the mounting angle between the mounting plate 1546 and the adjusting plate 1547, so that the guide ring 1541 is collinear with the axis of the cup placement groove 124.

[0070] A retaining bar 1548 is provided on the upper surface of the guide ring 1541. The retaining bar 1548 is used to make the axis of the paper cup colinear with the axis of the guide ring 1541 to prevent the cup tube from tilting. In addition, when producing some special paper cups, such as when a crack is opened in the cup wall at the upper end of the paper cup so that the cup mouth is petal-shaped, the retaining bar 1548 can also prevent the cup mouth from being opened too much and deformed when the paper cups are stacked.
