Description

[0035] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 1 The up and down directions are consistent with the Figure 1 The left and right directions are consistent with the Figure 1 The projection direction itself is consistent.

[0036] like Figures 1 to 4 As shown, this embodiment provides a cup holder conveying device, comprising a pick-up mechanism 1 and a feeding mechanism 2 having a feeding channel. The feeding channel of the feeding mechanism 2 is used to convey the cup holders. The pick-up mechanism 1 is used to pick up the cup holders from the feeding channel and place them on the production line. Each cup holder is provided with at least one cup. Finally, the cup holders and cup holders are wrapped with packaging film to complete the packaging process.

[0037] The retrieving mechanism 1 includes a base 101, a rotating base 102 rotatably mounted on the base 101, a retrieving seat 103 rotatably mounted on the rotating base 102, a first suction assembly 104, a second suction assembly 105, and a driver 106. The rotating base 102 is disposed such that its rotational axis and the retrieving seat 103's rotational axis are spaced apart and parallel to each other. The retrieving seat 103 is mounted eccentrically. The rotational axis of the rotating base 102 and the retrieving seat 103 are both horizontally disposed, and the rotational axis of the retrieving seat 103 rotates around the rotational axis of the rotating base 102. The driver 106 is directly or indirectly connected to the rotating seat 102 and the material picking seat 103, so that the rotating seat 102 and the material picking seat 103 rotate respectively. The driver 106 can be a motor that drives the rotating seat 102 and the material picking seat 103 to rotate at the same time. The driver 106 can also be two motors that drive the rotating seat 102 and the material picking seat 103 to rotate respectively. In this embodiment, one motor is used to drive the rotating seat 102 and the material picking seat 103 to rotate at the same time, which not only saves costs and reduces the volume of the material picking mechanism 1, but also allows the rotating seat 102 and the material picking seat 103 to rotate or stop at the same time, ensuring the rotation coordination of the rotating seat 102 and the material picking seat 103.

[0038] The first suction component 104 and the second suction component 105 can both be used to absorb a cup holder, which is generally a piece of paper or a paper holder. In this embodiment, the cup holder is a piece of paper and has a paper surface to be sucked. The first suction component 104 and the second suction component 105 are arranged on the material picking seat 103 at intervals along the circumference of the rotation axis of the material picking seat 103. The first suction component 104 and the second suction component 105 each have one, and the first suction component 104 and the second suction component 105 are distributed at 180 degrees. The first suction component 104 and the second suction component 105 are mirror-symmetrical. Since the material picking seat 103 is eccentrically installed, the first suction component 104 and the second suction component 105 can be closer to the feeding channel when sucking the cup holder and closer to the production line for cup holder packaging when transporting and placing the cup holder. The feeding channel is located along the travel path of the first and second suction assemblies 104, 105. A driver 106 is in transmission connection with the rotating base 102 and the material retrieving base 103 to drive the first and second suction assemblies 104, 105 to alternately approach and move away from the feeding channel. When the first suction assembly 104 approaches the feeding channel, the second suction assembly 105 moves away from it. When the first suction assembly 104 moves away from it, the second suction assembly 105 approaches it. By driving the rotating base 102 and the material retrieving base 103 to rotate, the driver 106 causes the first and second suction assemblies 104, 105 to alternately approach the feeding channel, allowing them to alternately pick up cup holders from the feeding channel and transport them to designated locations.

[0039] When the cup holder conveying device is in operation, the feeding mechanism 2 first conveys the cup holder along the feeding channel. The pick-up mechanism 1 is then activated, and the driver 106 drives the rotating base 102 to rotate, thereby driving the eccentrically mounted pick-up base 103 on the rotating base 102 and the first and second suction assemblies 104, 105 on the pick-up base 103 to alternately approach the feeding channel. This allows the first and second suction assemblies 104, 105 to alternately pick up the cup holder from the feeding channel. Because the pick-up base 103 can rotate relative to the rotating base 102, i.e., the pick-up base 103 can rotate either driven by the rotating base 102 or on its own, both the first and second suction assemblies 104, 105 can attract the cup holder in a direction perpendicular to the paper surface of the cup holder. This ensures that the first and second suction assemblies 104, 105 are perpendicular to the paper surface of the cup holder when picking up the cup holder. This allows the first and second suction assemblies 104, 105 to place the cup holder vertically on the production line. Exemplarily, the feed channel is located above the pick-up mechanism 1, and the production line for packaging cup holders is located below the pick-up mechanism 1. The cup holders are tilted downward with their paper-decorated surfaces facing downward. Driven by the rotating base 102, the first and second suction assemblies 104, 105 alternately approach the feed channel and absorb the cup holders. Driven by the pick-up base 103, the first and second suction assemblies 104, 105 rotate, causing them to absorb the cup holders in a direction perpendicular to the paper-decorated surfaces of the cup holders. After absorbing the cup holders, the first and second suction assemblies 104, 105 alternately approach the production line and place the cup holders on the production line from top to bottom, facilitating packaging of the cup holders and cup bodies together on the production line. By driving the rotating base 102 to rotate, the first suction component 104 sucks the cup holder upward while the second suction component 105 places the cup holder downward on the production line. The first suction component 104 sucks the cup holder upward while the second suction component 105 places the cup holder downward on the production line. When the first suction component 104 places the cup holder on the production line, the second suction component 105 is on a moving path close to the feeding channel. When the second suction component 105 places the cup holder on the production line, the first suction component 104 is on a moving path close to the feeding channel, thereby realizing continuous conveying of the cup holders, improving the conveying efficiency of the cup holders, and thereby improving the production efficiency of cup products.

[0040] Further, the base 101 is rotatably provided with an axle, the rotating seat 102 is in transmission connection with the driver 106 through the axle, the taking-out seat 103 is provided with a connecting shaft, the rotating seat 102 is provided with a shaft hole, the taking-out seat 103 is installed in the shaft hole of the rotating seat 102 through the cooperation of the connecting shaft, the bearing and the expansion sleeve and the connecting shaft is in transmission connection with the driver 106, so that the driver 106 can drive the rotating seat 102 and the taking-out seat 103 to rotate, the taking-out seat 103 can rotate around the rotating seat 102 at the same time, and the rotating seat 102 and the taking-out seat 103 complete one adsorption or placement of a paper tray every 120° and 180° respectively.

[0041] In one embodiment, the taking-out mechanism 1 further comprises a first driving wheel 107 rotatably provided on the base 101, a first driven wheel 108 rotatably provided on the rotating seat 102, and a first transmission belt 109 sleeved on the first driving wheel 107 and the first driven wheel 108. The base 101 is provided with a first tension wheel 119 to tension the first transmission belt 109, the driver 106 is in transmission connection with the first driving wheel 107 through a speed reducer 118, the first driven wheel 108 is in transmission connection with the rotating seat 102, so as to drive the rotating seat 102 to rotate, and when the rotating seat 102 rotates, the taking-out seat 103 can rotate around the rotating axis of the rotating seat 102. The diameter of the first driven wheel 108 is greater than that of the first driving wheel 107, the first driving wheel 107 and the first driven wheel 108 are driven to rotate by the driver 106, so as to drive the taking-out seat 103 and the rotating seat 102 to rotate around the rotating axis of the first driven wheel 108.

[0042] Further, the base 101 comprises a plurality of support plates, the plurality of support plates are connected in sequence to form an accommodation space, and the first driving wheel 107, the first driven wheel 108, the first transmission belt 109 and the first tension wheel 119 are located in the accommodation space to prevent dust.

[0043] Optionally, the base 101 is provided with an origin detection sensor 120. The origin detection sensor 120 is used to detect the position of the rotating seat 102, so as to facilitate the driver 106 to control the rotating seat 102 to rotate, and then the first taking-out assembly 104 and the second taking-out assembly 105 can be accurately controlled to take out the cup tray alternately.

[0044] Optionally, the retrieving mechanism 1 further includes a counterweight 110 disposed on the rotating seat 102. The counterweight 110 and the retrieving seat 103 are spaced apart along the radial direction of the first driven wheel 108, and the rotation axis of the rotating seat 102 is located between the counterweight 110 and the rotation axis of the retrieving seat 103. The projection of the rotating seat 102 along the rotation axis is elliptical or racetrack-shaped. The retrieving seat 103 is mounted on the end face of the rotating seat 102, close to one of the outer arc surfaces, and the counterweight 110 is sleeved on the other outer arc surface of the retrieving seat 103. Because the retrieving seat 103 is eccentrically mounted on the rotating seat 102, the counterweight 110 is provided on the rotating seat 102 to balance the weight of the retrieving seat 103 and the first and second suction assemblies 104, 105, thereby making the rotation of the rotating seat 102 more stable and improving the life of the rotating seat 102 and the wheel axle.

[0045] In one embodiment, the first suction assembly 104 includes a plurality of first suction elements 111. The second suction assembly 105 includes a plurality of second suction elements 112. The first suction elements 111 and the second suction elements 112 are suction cups or nozzles. The material picking base 103 has a first mounting surface 113 and a second mounting surface 114 facing away from each other. The plurality of first suction elements 111 are arranged at intervals on the first mounting surface 113, and the plurality of second suction elements 112 are arranged at intervals on the second mounting surface 114. The plurality of first suction elements 111 are arranged at intervals along the rotation axis of the material picking base 103, and the plurality of second suction elements 112 are arranged at intervals along the rotation axis of the material picking base 103. The plurality of first suction elements 111 and the plurality of second suction elements 112 improve the stability of the cup holder suction.

[0046] Furthermore, the material picking seat 103 has a first mounting surface 113 and a second mounting surface 114 that are opposite to each other, a plurality of first adsorbents 111 are mounted on the first mounting surface 113, and a plurality of second adsorbents 112 are mounted on the second mounting surface 114. When the material picking seat 103 rotates, the first adsorbents 111 and the second adsorbents 112 can alternately adsorb the cup holder in a direction perpendicular to the paper surface of the cup holder.

[0047] Optionally, the material picker 103 includes a U-shaped frame 121 and a first picker board 122 and a second picker board 123, both mounted on the U-shaped frame 121. The first picker board 122 and the second picker board 123 are respectively mounted on two outer sides of the U-shaped frame 121 that face away from each other, with the first mounting surface 113 located on the first picker board 122 and the second mounting surface 114 located on the second picker board 123. When the first picker board 122 and the second picker board 123 are mounted on the U-shaped frame 121, an avoidance groove is formed. One end of the first absorber 111 and one end of the second absorber 112 are both located within the avoidance groove, preventing interference between the first absorber 111 and the second absorber 112 and the U-shaped frame 121, thereby facilitating the installation of the first absorber 111 and the second absorber 112.

[0048] The U-shaped frame 121 forms a pipe groove. The inner wall of the pipe groove is provided with a first pipe joint 125, a second pipe joint 126, and a third pipe joint 127, which facilitate the connection of the pipes to the first and second absorbers 111, 112. The pipe groove not only reduces the weight of the U-shaped frame 121 but also prevents interference between the pipes and other components, facilitating pipe routing. By connecting the pipes to the pump, negative pressure is generated in the first and second absorbers 111, 112, thereby sucking the cup holder.

[0049] Furthermore, a rotating slip ring 124 is mounted on the base 101. This is an electrical component responsible for connecting the rotating body and transmitting energy and signals. A fourth pipe joint 128 is provided on the rotating slip ring 124. This connection connects the pipes and provides negative pressure to the first and second adsorbers 111, 112 on the retrieving seat 103. The rotating slip ring 124 is connected to the vacuum generator via the fourth pipe joint 128. The first and second pipe joints 125, 126 are each connected to the fourth pipe joint 128 via a third pipe joint 127. This allows the cup holder conveyor device to be routed using only four air pipes.

[0050] In one embodiment, the retrieving mechanism 1 further includes a positioning pulley 115 mounted on the base 101, a second driven pulley 116 rotatably mounted on the retrieving seat 103, and a second transmission belt 117 sleeved over the positioning pulley 115 and the second driven pulley 116. The positioning pulley 115 is fixedly mounted on the base 101 and is coaxially arranged with the first driven pulley 108. The axle of the first driven pulley 108 directly passes through the wheel hole in the positioning pulley 115 and is in transmission connection with the rotating seat 102, driving the rotating seat 102 to rotate. The positioning pulley 115 is fixed. The rotating seat 102 has an axial hole, and the retrieving seat 103 has a connecting shaft.

[0051] The driver 106 is in transmission connection with the rotating base 102 via a wheel axle. The retrieving base 103 is in transmission connection with the second driven pulley 116 via a connecting shaft extending through an axial hole. The rotating base 102 is equipped with a second tensioning pulley to tension the second transmission belt 117. The rotating base 102 is in transmission connection with the driver 106 to achieve rotation. Since the retrieving base 103 is mounted on the rotating base 102, it can rotate with the rotating base 102 around its axis. In addition, since the connecting seat on the material picking seat 103 passes through the axial hole on the rotating seat 102, the rotating seat 102 directly pushes the material picking seat 103 to rotate around the axis of the rotating seat 102 when it rotates. At the same time, through the cooperation of the positioning pulley 115, the second driven wheel 116, and the second transmission belt 117, the material picking seat 103 rotates around the rotation axis of the second driven wheel 116, realizing the self-rotation of the material picking seat 103, that is, the present application can simultaneously drive the rotating seat 102 and the material picking seat 103 to rotate around the rotation axis of the rotating seat 102 through the driver 106 to realize the revolution of the material picking seat 103, and can also drive the material picking seat 103 to revolve around its own axis to realize the self-rotation of the material picking seat 103.

[0052] Optionally, the gear ratio of the positioning pulley 115 and the second driven pulley 116 is 3:2, and the transmission ratio of the positioning pulley 115 and the second driven pulley 116 is 2:3, so that when the first suction assembly 104 or the second suction assembly 105 absorbs the cup holder, the first suction assembly 104 or the second suction assembly 105 rotates 120 degrees along with the wheel shaft and the rotating base 102, ensuring that the first suction assembly 104 or the second suction assembly 105 is perpendicular to the paper surface of the cup holder.

[0053] Optionally, the feeding mechanism 2 comprises a frame 201, a conveying wheel set rotatably mounted on the frame 201, a conveying belt set 202 mounted on the conveying wheel set, a transmission shaft 203 rotatably mounted on the frame 201, a one-way bearing set mounted on the transmission shaft 203 and in driving connection with the conveying wheel set, and a pusher 204 having an extension rod. The extension rod of the pusher 204 is in driving connection with the transmission shaft 203 to drive the one-way bearing set to rotate in one direction. A feeding channel is located on the conveying belt set 202, and has a feeding end 205 and a discharging end 206. The cup holder is stacked on the feeding channel from the feeding end 205 along the extension direction of the feeding channel, and then moves to the discharging end 206. The first suction assembly 104 and the second suction assembly 105 are alternately close to / away from the discharging end 206 of the feeding channel, and the taking mechanism 1 sucks the cup holder from the discharging end 206. Specifically, the one-way bearing set comprises at least one one-way bearing body 207, which can rotate freely in one direction and is locked in the other direction. The one-way bearing is also called overrunning clutch. The conveying belt set 202 comprises a plurality of conveying belts and conveying wheels for driving the conveying belts to move. The conveying belt can be a belt or a conveying chain. The one-way bearing set is in driving connection with the conveying wheels through the transmission shaft 203, so that the conveying belt can drive the cup holder to move. The pusher 204 is a pneumatic cylinder. By using the characteristic that the one-way bearing set can only rotate in one direction, the extension rod of the pusher 204 is extended, the extension rod drives the one-way bearing set to rotate in one direction through the transmission of the transmission shaft 203, so that the conveying belt drives the cup holder on the conveying belt to move in the direction close to the discharging end 206. When the extension rod of the pusher 204 is retracted, the transmission shaft 203 and the conveying belt are stationary. When the extension rod of the pusher 204 is extended again, the conveying belt continues to convey the cup holder, and finally realizes the intermittent feeding of the cup holder.

[0054] Further, the conveying belt group 202 has straight sections and inclined sections arranged in sequence. The straight sections extend horizontally, the inclined sections extend downwardly in a direction away from the straight sections, the feeding end 205 is located at one end of the straight sections, the other end of the straight sections extends in a direction close to one end of the inclined sections, and the discharging end 206 is located at the other end of the inclined sections. Specifically, the conveying belt group 202 includes a first conveying belt 209 and a second conveying belt 210.

The hexagonal shaft is a kind of transmission mechanism. It has the characteristics of compact structure, light weight, high stiffness and high speed performance, high carrying capacity, stiffness and bending resistance, long service life, etc. It is suitable for occasions that need to transmit large torque and large load. The hexagonal shaft of the present application can better maintain the shape unchanged when bearing torque and axial force, thereby improving the transmission stability and reliability of the feeding mechanism 2. The stress surface of the hexagonal shaft has six surfaces, which can better disperse stress and thus bear greater torque and pressure.

[0060] In one embodiment, the cup holder conveying device further comprises a blowing nozzle 208. The blowing nozzle 208 is installed on the rack 201 and located above the material falling end 206. The blowing nozzle 208 blows open the gap between adjacent cup holders, ensuring that the cup holder suction mechanism 1 does not suck two cup holders at the same time.

[0061] The cup holder conveying device of the present application has the characteristics of small size, simple maintenance and replacement, and low cost. The cup holder conveying device has high conveying speed, and can take 150 to 300 cup holders per minute, with high conveying efficiency.
