Description

Technical Field

[0001] The invention relates to the technical field of box folding machines, and in particular to an automatic forming box folding machine. Background Art

[0002] After the production and manufacturing of existing electronic products such as watches and cameras are completed, they need to be packaged in packaging boxes. The processed cardboard is folded in half by a box folding machine to form a packaging box, and the cardboard is placed in a discharge box of the box folding machine. The cardboard in the discharge box is transported to the conveying mechanism in the box folding machine by a suction cup picker. During the conveying process, the cardboard is folded into the shape of a packaging box by a forming mold. When the existing box folding machine uses the suction cup picker to pick up materials, the suction cup picker first needs to move to the discharge box, and then the suction cup on the suction cup picker generates suction through an air pump, and the bottom of the discharge box is sucked by suction. The cardboard on the upper part is adsorbed on the suction cup, and then the suction cup picker moves to the conveying mechanism of the folding machine. At this time, the suction on the suction cup is closed, and the cardboard falls onto the conveying mechanism by gravity, thereby completing the picking and unloading of the folding machine. The movement trajectory of the suction cup picker is realized through program programming, which causes the suction cup picker to have a certain stroke and poor continuity when picking and unloading. The suction cup picker will have a certain sense of pause in the process of picking and unloading, which leads to more time spent in the process of picking and unloading, thus affecting the working efficiency of the folding machine. Summary of the invention

[0011] Furthermore, the driving assembly is mounted on the frame and acts on the four rotating rods. When the rotating disk rotates continuously, the driving assembly causes the four rotating rods to rotate continuously and in the same direction.

[0012] Furthermore, the driving assembly comprises an inner gear ring mounted on the frame and coaxial with the rotating disk, and a driving gear meshing with the inner gear ring is fixedly mounted on one end of the rotating rod away from the arc-shaped abutment plate.

[0013] Furthermore, a ventilation piece is installed between the frame and the rotating disk, and an air suction pipe is connected between the four suction cup material picking arms and the ventilation piece. When the rotating disk continues to rotate, the ventilation piece is used to form a state where two suction cup material picking arms located above the axis of the rotating disk are in an air suction state, and two suction cup material picking arms located below the axis of the rotating disk are in an air-stopping state.

DETAILED DESCRIPTION

[0032] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] Embodiment 1

[0034] like Figure 1-Figure 7As shown, the automatic forming box folding machine 1 comprises a box folding machine 1, a conveying mechanism 2 is mounted on the box folding machine 1, a frame 3 is mounted on the box folding machine 1, and further comprises: a rotating disk 4, which is mounted on the frame 3 in a vertical direction and is located above the conveying mechanism 2, and the rotating disk 4 is driven by a driving force to form a rotating disk 4 rotating around its own central axis; preferably, as Figure 4 As shown, a reduction motor is installed on the frame 3, and a rod body is installed on the output shaft of the reduction motor through the frame 3, and one end of the rod body is connected to the center of the plane end of the rotating disk 4 to realize the rotation of the rotating disk 4 around its own central axis. The feeding mechanism 8 includes four mounting sleeves 801 installed on the rotating disk 4, and the four mounting sleeves 801 are distributed in a circular array around the central axis of the rotating disk 4. A suction cup material picking hand 802 is slidably installed on one end of the mounting sleeve 801, and the sliding paths of adjacent suction cup material picking hands 802 are perpendicular to each other, and the sliding paths of two suction cup material picking hands 802 spaced from each other are parallel to each other. Mutual spacing refers to two non-adjacent suction cup material picking hands 802, that is, there is a spacing between the two suction cup material picking hands 802. The discharge rack 9 is installed on the frame 3 and has a feeding port 10 at the bottom. Cardboard is stacked in the discharge rack 9 along the vertical direction; that is, the suction cup material picking hand 802 can pass through the feeding The opening 10 sucks and extracts the cardboard at the bottom of the material discharging rack 9. It should be noted that the material discharging opening 10 is slightly smaller than the size of the cardboard. When the suction cup material discharging hand 802 sucks the cardboard at the bottom of the material discharging rack 9, because the cardboard has certain bending properties and elastic reset characteristics, when the suction cup material discharging hand 802 drives the cardboard during the movement, the cardboard will be pulled out from the bottom of the material discharging rack 9 without destroying the shape of the cardboard. The linkage component 11 is installed between the mounting sleeve 801 and the frame 3 and acts on the suction cup material discharging hand 802. When the rotating disk 4 rotates, the linkage component 11 is used to make the suction cup material discharging hand 802 move along the length direction of the corresponding mounting sleeve 801. Specifically, when the rotating disk 4 is rotating, because the mounting sleeve 801 is installed on the rotating disk 4, the rotating disk 4 will cause the mounting sleeve 801 to rotate during the rotation, thereby causing multiple suction cup material discharging hands 802 to rotate around the axis direction of the rotating disk 4. Figure 3 As a reference, for the convenience of explanation, the suction cup material taking hand 802 on the left side above the central axis of the rotating disk 4 is taken as the starting point, and is named A, B, C, and D in a clockwise direction. Figure 3In the state shown, the linkage assembly 11 will make A away from the corresponding installation sleeve 801, so that A is vertically upward, B is close to the corresponding installation sleeve 801, C is away from the corresponding installation sleeve 801, so that C is vertically downward, and D is close to the corresponding installation sleeve 801. That is to say, A is in the state of adsorbing the cardboard, B is in the state of transporting the cardboard, C is in the state of placing the cardboard, and D is in the state of preparing to adsorb and transport the cardboard. During use, the movement state of D is used for explanation, and the movement states of A, B and C are all consistent with D. Figure 3 As shown, the rotating disk 4 continues to rotate clockwise, and when D moves to the state A, the linkage assembly 11 will cause D to move away from the corresponding installation sleeve 801, so that D gradually approaches the discharge port. In the process of D moving to the A state, D (suction cup material picker 802) is in the suction state until D moves to the A state, at which time the suction cup of D is located directly below the stacked cardboard. At this time, the cardboard at the bottom is adsorbed on D by the suction cup on D, and D moves to the B state at this time. In the process of D moving to the B state, D moves in the direction close to the corresponding installation sleeve 801, which is referred to as "retraction" here. At this time, the suction cup of D is still in the suction state. When D moves to and forms the B state, D moves in the direction of C. In the process of D moving to the C state, D is in the direction of moving away from the corresponding installation sleeve 801, which is referred to as "protrusion" here. When D moves to the C state, the suction cup on D does not generate suction, so that the cardboard on D falls onto the conveying mechanism 2 under the action of gravity. , thus completing the material discharge, at this time D returns to the initial starting state with the movement of the rotating disk 4, and during the movement of D, D will shrink and no suction will be generated, and so on, so that the movement law of the four suction cup material taking hands 802 after the rotating disk 4 rotates one circle is to extend forward, shrink backward, extend forward, shrink backward... and the suction cup material taking hand 802 is always in the suction state when it is located above the central axis of the rotating disk 4, ensuring that the cardboard is adsorbed on the suction cup material taking hand 802 and will not fall off, and the suction cup material taking hand 802 located below the central axis of the rotating disk 4 2 does not generate suction when it moves to the C state and the D state, that is, the suction cups in the A state and the B state are in the suction state, and the C state and the D state are in the air-off state, so that the rotating disk 4 is continuously rotating, and the four suction cup material picking hands 802 are always continuously picking up and putting down materials through the linkage assembly 11 when the rotating disk 4 is continuously rotating, and the action is continuous, there is no jamming phenomenon in the process of conveying cardboard, and the movement stroke is short, which reduces the time required for picking up and putting down materials, so as to improve the working efficiency of the box folding machine 1.

[0035] like Figure 1-3 and Figure 5As shown, in some embodiments, one end of the suction cup material picking hand 802 is movably inserted in the installation sleeve 801, and the linkage assembly 11 includes a rotating rod 1101 rotatably installed on the installation sleeve 801, and a through slot 1102 is opened on one side of the installation sleeve 801 along its length direction. A column 1105 passing through the through slot 1102 and located outside is constructed on one side of the suction cup material picking hand 802, one end of the rotating rod 1101 is located outside and is constructed with an arc-shaped abutment plate 1103, and a return spring 1104 is installed between the installation sleeve 801 and the suction cup material picking hand 802. Specifically, as shown in FIG. Figure 3 As shown, the suction cup material picking hand 802 is composed of a connecting frame, four suction cups distributed in a rectangular shape, and a transmission plate. The four suction cups are installed on the connecting frame, and the transmission plate is installed on the side of the connecting frame away from the suction cups. The transmission plate is slidably inserted in the installation sleeve 801, and the column 1105 is installed on the transmission plate. Every two adjacent ones of the four suction cups are connected by an air pipe. In this embodiment, one of the air pipes is connected to a connecting pipe, and the connecting pipe can be connected to an external air source to control the air suction and air stop of the four suction cups. A driving component 12 for driving the rotating rod 1101 to rotate continuously is installed on the frame body 3, so that the outer arc surface of the arc-shaped abutment plate 1103 intermittently abuts against the corresponding column 1105, so as to form the suction cup material picking hand 802 to move along the length direction of the corresponding installation sleeve 801, as shown in FIG. Figure 2 As shown, during the continuous clockwise rotation of the rotating disk 4, the arc-shaped abutment plate 1103 will continue to rotate counterclockwise. During the process of D rotating to the A state, the arc-shaped abutment plate 1103 rotates 180 degrees counterclockwise, so that when D rotates to A, the outer arc surface of the arc-shaped abutment plate 1103 contacts with the column 1105. When D rotates to the A state, it is in the extended state. At this time, the rotating disk 4 rotates continuously, and the arc-shaped abutment plate 1103 also rotates continuously, so that the arc-shaped abutment plate 1103 is disengaged from the corresponding column 1105, thereby achieving intermittent contact. When the A state rotates to the B state, as the rotation progresses, the column 1105 is disengaged from the arc-shaped abutment plate 1103. The corresponding suction cup material picking hand 802 is retracted through the return spring 1104, so when A rotates to B, the suction cup material picking hand 802 is in a retracted state, and when the A state is rotated to the B state, the arc-shaped support plate 1103 also continues to rotate with the rotation of the rotating disk 4. However, in the process of rotating from the A state to the B state, the arc-shaped support plate 1103 does not form a conflict with the column rod 1105 during the rotation process, so the suction cup material picking hand 802 is in a contracted state at this time. In the process of rotating from D to B at this time, the arc-shaped support plate 1103 just rotates one circle, thereby realizing the back and forth switching of A, B, C, and D between the two states of extension and retraction during the rotation process.

[0036] like Figure 1 , Figure 4 and Figure 5As shown, in some embodiments, the driving component 12 is installed on the frame 3 and acts on the four rotating rods 1101. When the rotating disk 4 rotates continuously, the driving component 12 is used to make the four rotating rods 1101 rotate continuously and in the same direction. The driving component 12 makes the four rotating rods 1101 rotate continuously, thereby realizing the continuous rotation of the four arc-shaped abutment plates 1103. There is no need to install multiple electric driving elements on the rotating disk 4 to keep the four arc-shaped abutment plates 1103 rotating continuously, thereby saving energy consumption.

[0037] like Figure 1-5 As shown, in some embodiments, the driving assembly 12 includes an inner gear ring 1201 installed on the frame 3 and coaxial with the rotating disk 4, and a driving gear 1202 meshing with the inner gear ring 1201 is fixedly installed at one end of the rotating rod 1101 away from the arc-shaped abutment plate 1103. When the rotating disk 4 continues to rotate, because the four driving gears 1202 are all meshed with the inner gear ring 1201, the four driving gears 1202 will rotate simultaneously during the rotation of the rotating disk 4, thereby realizing the simultaneous rotation of the four rotating rods 1101 It should be noted that the ratio of the number of teeth on the outer ring of the driving gear 1202 to the number of teeth on the inner ring of the inner gear ring 1201 is one to two. In this way, when the driving gear 1202 rotates ninety degrees along with the rotating disk 4, the driving gear 1202 itself rotates one hundred and eighty degrees. That is to say, when D rotates to the A state, the corresponding driving gear 1202 rotates to one hundred and eighty degrees, which not only realizes the simultaneous rotation of the four arc-shaped abutment plates 1103, but also ensures that the four suction cup material picking hands 802 repeat the two states of extending and retracting in sequence.

[0038] like Figure 1-5 As shown, in some embodiments, a ventilation piece 13 is installed between the frame 3 and the rotating disk 4, and an air suction pipe 14 is connected between the four suction cup material taking hands 802 and the ventilation piece 13. When the rotating disk 4 continues to rotate, the ventilation piece 13 is used to form that the two suction cup material taking hands 802 located above the axis of the rotating disk 4 are in an air suction state, and the two suction cup material taking hands 802 located below the axis of the rotating disk 4 are in a stop state. That is to say, the ventilation piece 13 can be used to realize that during the continuous rotation of the rotating disk 4, Figure 3 As shown, state A and state B are in the suction state at this time, so as to keep the cardboard adsorbed on the suction cup picking hand 802 and prevent it from falling off, and state C and state D are in the air-stop state, so as to place the adsorbed cardboard on the conveying mechanism 2 and prepare to adsorb the cardboard again. The design of the ventilation piece 13 makes it unnecessary to install a pneumatic solenoid valve on the pipeline of the suction cup picking hand 802 to realize the timed control of suction and air-stop, thereby improving the continuity of picking and discharging, and at the same time, there is no need to use multiple pneumatic solenoid valves, thereby further saving energy consumption.

[0039] like Figure 1-7As shown, in some embodiments, the ventilator 13 includes a ventilator 1301 installed at the center of one side of the rotating disk 4, four air intake pipes 14 are distributed in a circular array and connected to the outer peripheral side of the ventilator 1301, and an air intake pipe 1302 with one end inserted into the interior of the ventilator 1301 is horizontally installed on the frame 3. Specifically, one end of the air intake pipe 1302 located inside the ventilator 1301 contacts with one end inside the ventilator 1301, and the air intake pipe 1302 is located inside the ventilator One end of the interior of 1301 is sealed and one side is provided with a vent hole 1303 located inside the vent cylinder 1301. One side of the air inlet pipe 1302 is configured with a blocking block 1304 that fits the inner wall of the vent cylinder 1301. In other words, the vent hole 1303 is not opened on the blocking block 1304, and the connection between the suction pipe 14 of the two suction cup material picking hands 802 located below the axis of the rotating disk 4 and the vent cylinder 1301 is blocked by the blocking block 1304. Figure 3 As shown, that is, C and D block the connection between the air hole 1303 and the air pump 15 through the blocking block 1304, and the frame 3 is equipped with an air pump 15, which is connected to the free end of the air inlet pipe 1302. The air pump 15 is in a continuously open state and the suction end is connected to the air inlet pipe 1302. When the air pump 15 provides suction to the air inlet pipe 1302, at this time, because the suction pipes 14 of A and B are connected to the air cylinder 1301, the A state and the B state are always in a state of adsorbing the cardboard, thereby ensuring that the cardboard will not fall from A and B. The rotating disk 4 will drive the air cylinder 1301 to rotate during the rotation process, and the air inlet pipe 1302 is always in a stationary state, so A and B located above the central axis of the rotating disk 4 are always in a suction state, while C and D are kept in a stopped state because their connection is blocked by the blocking block 1304.

[0040] like Figure 1-5 As shown, in some embodiments, the air inlet pipe 1302 is a hard pipe and an annular groove 5 is opened on the outer side, a sealing ring 6 is installed in the annular groove 5, and a connecting sleeve 7 is constructed at one end of the vent tube 1301. The connecting sleeve 7 is sleeved on the air inlet pipe 1302 and the sealing ring 6 is in contact with the inner wall of the connecting sleeve 7. The design of the sealing ring 6 prevents leakage from occurring on the contact surface between the connecting sleeve 7 and the air inlet pipe 1302 during the rotation of the rotating disk 4, and prevents A and B from falling off during the process of adsorbing the cardboard. Preferably, the connecting sleeve 7 and the air inlet pipe 1302 can also be connected by a rotating joint, which can also achieve a sealing effect.

[0041] like Figure 2 , Figure 3 and Figure 5As shown, in some embodiments, a holding plate 16 is vertically slidably installed on the top of the unloading rack 9, and a transmission member 17 is installed on the unloading rack 9 to drive the holding plate 16 to move in the vertical direction. The holding plate 16 is formed to contact the top of the stacked cardboard through the transmission member 17. The design of the transmission member 17 can make the holding plate 16 always contact the top of the stacked cardboard, ensuring that the cardboard located below is fully in contact with the bottom end of the unloading rack 9. It should be noted that the resistance force provided by the transmission member 17 will not affect the normal adsorption of the suction cup material picking hand 802. The design of the transmission member 17 mainly prevents the suction cup material picking hand 802 from not being able to fully contact the bottom of the cardboard located below when moving to the bottom of the cardboard located below, thereby indirectly improving the adsorption effect.

[0042] like Figure 1-4 As shown, in some embodiments, the transmission member 17 includes a driving plate 1701 with one end rotatably mounted on the material unloading rack 9 in a vertical direction, and a guide rod 1703 is vertically configured on the top of the holding plate 16, such as Figure 3 As shown, the guide rod 1703 is slidably sleeved on the material rack 9, and the guide rod 1703 is quadrilateral, so the guide rod 1703 can only move vertically and will not rotate along its own central axis. A resistance rod 1702 is constructed on one side of the guide rod 1703. When the driving plate 1701 rotates upward, the driving plate 1701 and the resistance rod 1702 form a resistance to make the guide rod 1703 move vertically. A counterweight block 1704 is installed on the holding plate 16. The transmission member 17 is in the first embodiment. The design of the counterweight block 1704 can make the holding plate 16 always aligned with the stacked The cardboard forms a resistance force, thereby ensuring that the suction cup on the suction cup material picker 802 can better contact with the cardboard, thereby improving the adsorption effect, and when the folding machine 1 needs to add cardboard during operation, it only needs to lift the driving plate 1701. Preferably, a handle is installed on the free end of the driving plate 1701 to facilitate the staff to use the driving plate 1701, and when the driving plate 1701 rotates upward, it will form a resistance force with the resistance rod 1702, so that when the driving plate 1701 is lifted upward, the holding plate 16 is indirectly lifted through the resistance rod 1702, thereby facilitating the addition of cardboard.

[0043] Embodiment 2

[0044] Different from the transmission member 17 in the first embodiment, another transmission member 17 is disclosed in this embodiment. The remaining technical features are the same as those in the first embodiment, and the difference lies in that a different transmission member 17 is used.

[0045] like Figure 5 like Figure 8As shown, in some embodiments, the transmission member 17 includes a sleeve plate 18 vertically constructed on the top of the holding plate 16, a baffle plate 19 is vertically slidably installed inside the sleeve plate 18, a resisting spring 20 is installed between the bottom of the baffle plate 19 and the sleeve plate 18, a connecting rod 21 is constructed on the top of the baffle plate 19, one end of the connecting rod 21 is located outside and a transmission frame 22 is installed, a threaded rod 23 is vertically and rotatably installed on the discharge rack 9, the transmission frame 22 is threadedly sleeved on the threaded rod 23, when the threaded rod 23 is rotated, the transmission frame 22 and the threaded rod 23 are threadedly matched, the connecting rod 21 will move downward, and the connecting rod 21 will drive the baffle plate 19 installed on the connecting rod 21 to move downward, because the baffle plate 19 and the sleeve plate 18 The two are connected by the resistance spring 20, so the holding plate 16 will also move downward. When the holding plate 16 contacts the stacked cardboard, the threaded rod 23 is continuously rotated to move the connecting rod 21 downward, thereby stretching the resistance spring 20. The pressing force generated by the elastic deformation of the resistance spring 20 is used to make the holding plate 16 contact the stacked cardboard. Compared with the transmission member 17 in the first embodiment, it has a certain self-locking property and is not easily affected by external collisions to cause the holding plate 16 to move on its own. It has higher safety. The transmission member 17 in the first embodiment is more convenient when adding cardboard.
