Description

Horizontal oral liquid cartoning machine

Technical Field

The utility model relates to the technical field of packaging equipment, in particular to a horizontal oral liquid boxing machine.

Background

In the beverage and oral liquid production industry, various boxing machines for external packing boxes are needed, wherein book-type packing boxes are generally used for completing the procedures of putting and boxing bottled contents in the packing boxes on a horizontal boxing machine, and oral liquid packaged by the packing boxes is one of the main forms of the bottled contents. The existing horizontal boxing machine generally comprises an oral liquid feeding conveyer belt for conveying upright packaging bottles, a bottle inverting mechanism for enabling the upright packaging bottles to lie flat, a bottle inverting conveyer belt for conveying the flat packaging bottles, a paper box feeding conveyer belt for conveying packaging boxes and a boxing robot for putting the packaging bottles into the packaging boxes.

For the packing procedure of the oral liquid adopting the book-shaped packing box, the important step is to open the cover, namely to rotate and open the upper cover of the packing box. It is known that a so-called book-type package comprises a bottom box having a peripheral edge, a lid closing the bottom box, and a plurality of separating ribs provided in the bottom box for receiving a corresponding number of packages. Wherein one side of the box cover is connected with the side of the bottom box, and the joint of the side of the box cover and the side of the bottom box forms a rotating axis of the box cover. When the box cover needs to be opened or closed, the box cover needs to rotate relative to the rotating shaft.

In addition, in the existing horizontal oral liquid boxing machine, people usually adopt corresponding 'manipulators' to open the box cover or close the box cover so as to improve the boxing production efficiency. Vacuum chucks are typically included on the robot to securely hold the bottom and lid.

However, the existing horizontal oral liquid boxing machine has the following technical defects: firstly, the oral liquid feeding conveyer belt, the bottle inverting mechanism, the bottle inverting conveyer belt and other mechanisms are customized according to the specific requirements of specific packaging boxes, so that the application range is narrow, when the specifications and models of products are more, different box packing machines need to be configured, the early investment and the production cost are increased, and the regulation and control which are not beneficial to the production rhythm are realized. In addition, since the overall size of the book-type packing box may vary and accordingly the rotation axis thereof may vary, it is difficult for the robot to be concentric with the rotation axis after the robot sucks the box cover. Therefore, in the process that the manipulator drives the box cover to rotate, certain displacement exists between the vacuum chuck of the manipulator and the box cover, so that the displacement of the packaging box is easily caused, particularly, the vacuum chuck of the manipulator is easily separated from the box cover, and the box cover can fall off from the manipulator in serious conditions.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a horizontal oral liquid cartoning machine, including the oral liquid feeding conveyer belt that is used for carrying upright packing bottle, bottle mechanism, the bottle conveyer belt that falls that is used for carrying the packing bottle of keeping flat, carton feeding conveyor, the cartoning robot, characterized by, be equipped with the lane dividing plate between oral liquid feeding conveyer belt and bottle mechanism, be equipped with the parting bead that a plurality of extension degree directions extend on the lane dividing plate at intervals, form the lane dividing groove that can hold the packing bottle between the adjacent parting bead, the end that is connected at oral liquid feeding conveyer belt and lane dividing plate is equipped with the adjustment mechanism that can block up the lane dividing groove, thereby will the lane dividing groove divide into open lane dividing groove and confined lane dividing groove.

The utility model comprises an oral liquid feeding conveyer belt for conveying upright packaging bottles and a paper box feeding conveyer device for conveying packaging boxes. Therefore, when the packaging bottles are conveyed forwards to be close to the corresponding packaging boxes, the boxing robot can grab the packaging bottles with the set number and place the packaging bottles into the packaging boxes to complete the boxing procedure of the oral liquid.

It can be understood that the so-called horizontal oral liquid boxing box is mainly used for placing packaging bottles of oral liquid and the like into book-shaped packaging boxes. For this reason, a bottle pouring mechanism is required to be arranged so that the upright packing product can be turned on one side and is called a flat packing bottle; a bottle inverting conveyer belt for bearing the packing bottles which are horizontally placed; the carton feeding and conveying device should comprise a carton opening mechanism for opening the upper cover of the carton. Because the existing horizontal boxing machine is provided with the mechanism and the device, namely, the existing mechanism and the device can be adopted to complete the boxing process of the packaging bottles.

In addition, the utility model is provided with a channel plate between the oral liquid feeding conveyer belt and the bottle pouring mechanism, and the channel plate is provided with a plurality of channel grooves formed by separating sheets. Like this, when upright placing the packing bottle on oral liquid feeding conveyer belt and being carried oral liquid feeding conveyer belt end, the packing bottle is in the lane groove that the difference is different respectively to make packing bottle separate each other, and form the row number that matches with required packing bottle quantity in the packing carton, so that follow-up dress box robot accurately snatchs the packing bottle.

In particular, the utility model is provided with an adjusting mechanism which can block the channel dividing groove at the tail end of the oral liquid feeding conveyer belt connected with the channel dividing plate. Therefore, the number of the branch grooves can be set according to the maximum number of the packaging bottles which can be accommodated by the packaging box, and when the packaging box needs to be packaged, the corresponding branch grooves are plugged by the adjusting mechanism according to the number of the packaging bottles which can be accommodated by the packaging box, so that the opened branch grooves which are equal to the number of the packaging bottles which can be accommodated by the packaging box are formed, and the packaging box can be suitable for packaging of packaging boxes with different specifications.

Preferably, the adjusting mechanism comprises a door-shaped frame positioned above the oral liquid feeding conveying belt, and a blocking block used for blocking the channel dividing groove is detachably arranged on the door-shaped frame.

The plugging blocks with corresponding quantity can be arranged according to the requirement so as to conveniently open the required quantity of the shunting grooves.

Preferably, the carton feeding and conveying device comprises a carton feeding and conveying belt for conveying upright packages, an equidistant conveying belt for conveying flat packages, a box turning mechanism for converting the upright packages into the flat packages, and a box pushing mechanism for pushing the upright packages to the box turning mechanism.

The paper box feeding and conveying device comprises a paper box feeding conveying belt, an equidistant conveying belt, a box turning mechanism and a box pushing mechanism. The packing carton gets into carton feeding conveyer belt earlier and moves forward, because the packing carton on the carton feeding conveyer belt is upright placing, consequently can "bundle into the packing carton of placing of pile", reduces the occupation space of carton feeding conveyer belt packing carton greatly to the packing carton that makes things convenient for is placed on carton feeding conveyer belt. When the packaging box belt moves forwards to the box pushing mechanism, the box pushing mechanism acts, and therefore the packaging box with the most upright front end is pushed to the box turning mechanism transversely. At the moment, the box turning mechanism acts to enable the upright packing boxes to rotate 90 degrees to be in a flat-laying state, and the packing boxes are horizontally laid on the equidistant conveying belt to move forwards at intervals. That is to say, carton feeding conveyor on the one hand changes packing carton from upright state into the state of keeping flat to conveniently put into the packing bottle and box. On the other hand, the packing boxes can be conveyed forwards at intervals, so that a subsequent box packing robot can accurately place the packing products into the packing boxes.

Preferably, the bottle inverting mechanism comprises a bottle inverting roller, a plurality of cylindrical accommodating grooves capable of accommodating packaging bottles are formed in the circumferential surface of the bottle inverting roller, each accommodating groove corresponds to the corresponding lane groove, the axis of each accommodating groove is located in the tangential direction of the bottle inverting roller, the bottle inverting roller is provided with a bottle receiving position and a bottle inverting position, and when the bottle inverting roller is located at the bottle receiving position, the openings of the accommodating grooves are vertically upward; when the bottle-pouring roller rotates 95-110 degrees to the bottle-pouring position, the opening of the accommodating groove inclines downwards.

When the upright packaging bottle moves to the bottle inverting roller, the packaging bottle can enter the corresponding accommodating groove, and the bottle inverting roller rotates at least 90 degrees at the moment, so that the packaging bottle is changed from an upright state to a flat state, slides out of the accommodating groove and enters the bottle inverting conveyer belt to move forwards continuously. Particularly, when the bottle inverting roller rotates by 95-110 degrees, the packaging bottles can be rotated to a state that the front ends of the packaging bottles are inclined downwards, so that the packaging bottles can slide out of the accommodating grooves under the action of self gravity and enter the bottle inverting conveying belt, and meanwhile, the packaging bottles are prevented from sliding out of the accommodating grooves forwards firstly when the bottle inverting roller is not rotated in place.

Preferably, the box opening device also comprises a box opening mechanism for opening the cover of the packing box, the box opening mechanism comprises a lower sucker for adsorbing the bottom box of the packing box, an upright frame, a mounting plate arranged on the frame, a stepping motor arranged on one side of the mounting plate, a driving rod arranged on the other side of the mounting plate and a driven shaft, a transverse output shaft of the stepping motor is connected with one end of the driving rod, one end of the driven rod is connected with the driven shaft, the other end of the driving rod is rotatably connected with one end of a long connecting rod, the middle part of the long connecting rod is rotatably connected with the middle part of the driven rod so as to enable the driven rod to be parallel to the driving rod, the other end of the driven rod is rotatably connected with one end of a short connecting rod, the other end of the short connecting rod is rotatably connected with one end of a box opening rod, the other end of the box opening rod is rotatably connected with the other end of the long connecting rod so as to enable the short connecting rod to be parallel to the long connecting rod, and the box opening rod is parallel to the driven rod, the box opening rod is provided with a box opening arm, the box opening arm is provided with a box opening sucker, and the intersection point of the connecting line between the output shaft and the driven shaft and the extension line of the box opening rod coincides with the rotation center of the box cover.

Book-type packages are known as the primary packaging form for oral liquids. Accordingly, when packaging, the lid of the packaging box needs to be grasped and rotated open by the corresponding robot. The component of such a robot gripping cassette lid is usually a vacuum chuck. Because the lid has fixed rotation center when rotating to open, consequently, vacuum chuck need rotate around the rotation center with the rotation center coincidence, when the size specification of packing carton changes, rotation center and rotation center are difficult to effective coincidence to lead to producing the displacement between vacuum chuck and the lid, and then make vacuum chuck and lid have the risk of breaking away from each other, influence the success rate that the lid was opened.

The cover opening mechanism comprises a lower sucker, a box opening sucker and a parallelogram connecting rod structure consisting of a plurality of rod pieces. The lower sucker firstly adsorbs the bottom box of the fixed packing box, the stepping motor drives the box opening arm to rotate through the parallelogram connecting rod structure, then the box opening sucker on the box opening arm drives the box cover to rotate and open, and the intersection point of the connecting line between the output shaft and the driven shaft and the extension line of the box opening rod is the rotation center of the box opening arm and the box opening sucker. Because the intersection point of the connecting line between the output shaft and the driven shaft and the extension line of the box opening rod coincides with the rotation center of the box cover, namely, the rotation center of the box opening sucker coincides with the rotation center of the box cover, the relative displacement between the box opening sucker and the box opening sucker can be avoided in the process of opening the box cover in a rotating mode, and then reliable adsorption and grabbing of the box cover by the box opening sucker can be guaranteed. That is, in this aspect, the parallelogram linkage structure corresponds to a transmission mechanism between the stepper motor and the box opening arm and the box opening suction cup.

When the size specification of packing carton changes, that is to say, when the rotation center position of lid has the adjustment, we can conveniently adjust the position of rotation center through adjusting the position of mounting panel in the frame. It should be noted that, if the output shaft of the stepping motor directly drives the box opening arm and the box opening suction cup to rotate, that is, the output shaft of the stepping motor is the rotation center of the box cover, and the size of the packing box is limited, collision interference among the output shaft of the stepping motor, the box opening arm, the box opening suction cup and the packing box is very easy to cause. The stepping motor is connected with the box opening arm and the box opening sucker through the parallelogram connecting rod structure, so that an output shaft of the stepping motor can deviate from the box opening arm, the box opening sucker and the packaging box, the assembly is convenient, and the collision interference among the output shaft of the stepping motor, the box opening arm, the box opening sucker and the packaging box can be effectively avoided. When the position of the mounting plate on the rack is adjusted, the positions of the box opening arm and the box opening sucker connected to the quadrilateral connecting rod structure need to be adjusted again to ensure that the box opening sucker can adsorb the proper position of the box cover, namely, the rotating radius of the box opening sucker needs to be adjusted. Because the driving rod, the driven rod and the box opening rod on the parallelogram connecting rod structure are always kept parallel, the rotation angle of the box opening sucker is equal to the rotation angle of the box opening rod, the rotation angle of the driving rod and the rotation angle of the stepping motor. Therefore, the rotating radius of the box opening sucker can be conveniently adjusted only by adjusting the included angle between the initial position of the driving rod and the long connecting rod, and meanwhile, the rotating angle of the stepping motor does not need to be reset, so that the use and the regulation are convenient.

As preferred, the equidistance conveyer belt includes equidistant transfer chain, connects the linking transfer chain of equidistant transfer chain front end, the equidistant transfer chain includes by step motor driven two spacing hold-in ranges of the left and right sides, and spacing ground is equipped with a plurality of preceding spacing blocks on one of them spacing hold-in ranges, is equipped with the back spacing block that corresponds with preceding spacing block on another spacing band, form the interval that holds that matches with packing carton width size on the antedisplacement direction between preceding spacing block and the back spacing block that corresponds, link up the transfer chain and include by motor drive two about linking hold-in ranges, link up the upper strata of hold-in ranges and be higher than spacing hold-in ranges upper strata, be equipped with the transport guide rail that is higher than spacing hold-in ranges upper strata outside spacing hold-in ranges interval.

In the scheme, the packing box which is turned to be in a flat state by the box turning mechanism enters and is borne on two connecting synchronous belts of a connecting conveying line and moves forwards to the tail end of the connecting conveying line; at the moment, the packing boxes sequentially fall into the accommodating gaps on the left and right spacing synchronous belts and are accurately positioned, a fixed space is formed between the front and back adjacent packing boxes, the stepping motor drives the left and right spacing synchronous belts to move forwards, and the conveying guide rail is higher than the upper layer of the spacing synchronous belts, so that the left and right sides of the packing boxes are slidably supported on the conveying guide rails on the left and right sides. That is to say, two preceding spacing piece on the spacing hold-in range of controlling, back spacing piece play the effect that makes the accurate location of packing carton on the one hand, and on the other hand starts the effect that promotes packing carton and move forward on conveying guide. Because the two sides of the packing box are supported on the conveying guide rail, the stability of the packing box can be ensured, the packing box manipulator can conveniently place the packing bottle into the packing box, the phenomenon that the packing box supported on the limiting synchronous belt is easy to shake left and right and up and down is avoided, and the accurate positioning of the packing box is facilitated.

It can be understood that a plurality of equidistant conveying lines are arranged, the conveying lines are connected, and long-distance equidistant conveying of the packing boxes can be conveniently realized.

Therefore, the utility model has the following beneficial effects: the method is suitable for the production of various packing box specifications; the rotation center of the manipulator can be ensured to be coincided with the rotation axis of the box cover all the time, and the packing box is prevented from falling off from the manipulator.

Detailed Description

The utility model is further described with reference to the following detailed description and accompanying drawings.

As shown in fig. 1 and 2, a horizontal oral liquid boxing machine is suitable for packing oral liquid and other packaging bottles into book-shaped packaging boxes. The oral liquid packing box packing machine comprises an oral liquid feeding conveyer belt 1 for conveying upright packing bottles, a bottle inverting mechanism 2, a bottle inverting conveyer belt 3 for conveying flat packing bottles, a paper box feeding conveyer device 4 and a box packing robot 5, wherein a plurality of separating sheets 61 extending in the extension direction are arranged above the oral liquid feeding conveyer belt close to the bottle inverting mechanism at intervals, a channel dividing groove 62 capable of containing packing bottles is formed between every two adjacent separating sheets, and an adjusting mechanism 7 capable of plugging the channel dividing groove is arranged at the tail end of the oral liquid feeding conveyer belt connected with the channel dividing plate, so that the channel dividing groove is divided into an open channel dividing groove and a closed channel dividing groove, and the box packing of the horizontal oral liquid packing machine comprises the following steps:

a. a plurality of packaging bottles 91 vertically placed on the oral liquid feeding conveyer belt are conveyed to the tail end of the oral liquid feeding conveyer belt, and at the moment, the vertical packaging bottles enter the opened shunting grooves;

b. the subsequent packaging bottles push the packaging bottles in front of the lane dividing groove to move to the tail end of the lane dividing plate, and the bottle inverting mechanism enables the packaging bottles to turn over to be in a flat state;

c. the packing bottles which are horizontally placed enter a bottle inverting conveyer belt;

d. simultaneously with the movement of the packaging bottles, the carton feeding and conveying device enables the packaging boxes 90 to move forwards synchronously along with the packaging bottles, and at the moment, the packaging boxes are positioned beside the packaging bottles;

e. and the boxing robot grabs the horizontally placed packaging bottles and puts the required number of packaging bottles into the corresponding packaging boxes, so that boxing of the horizontal boxing machine is completed.

The boxing robot can grasp the packaging bottle by suction through a vacuum chuck. In addition, the packing bottle is placed on oral liquid feeding conveyer belt at the initial state vertically, can avoid the random roll of packing bottle on the one hand, on the other hand, is favorable to reducing the arrangement space of packing bottle. Therefore, a corresponding bottle pouring mechanism needs to be arranged, so that the upright packaging bottles turn on one side and are called flat packaging bottles, and the boxing robot can grab the bottles conveniently.

Because the bottle inverting conveyer belt, the bottle inverting mechanism and the like are existing mechanisms and devices in the existing horizontal boxing machine, namely, the existing mechanisms and devices can be adopted to complete the boxing procedure of the packaging bottles.

In particular, a plurality of dividing grooves formed by dividing sheets are arranged between the oral liquid feeding conveyer belt and the bottle pouring mechanism. Like this, when the packing bottle of placing upright on oral liquid feeding conveyer belt was carried oral liquid feeding conveyer belt end, the packing bottle gets into different minute inslot respectively to make packing bottle separate each other and pinpoint, and form the column number that matches with required packing bottle quantity in the packing box, so that follow-up dress box robot accurately snatchs the packing bottle.

Because the tail end of the oral liquid feeding conveying belt connected with the channel dividing grooves is provided with the adjusting mechanism capable of plugging the channel dividing grooves, the number of the channel dividing grooves can be set according to the maximum number of packaging bottles which can be contained in the packaging box. When the packaging box needs to be packaged, the corresponding lane grooves can be plugged through the adjusting mechanism according to the number of the packaging bottles which can be accommodated by the packaging box, so that the opened lane grooves which are equal to the number of the packaging bottles which can be accommodated by the packaging box are formed, and the packaging box can be further suitable for packaging of packaging boxes with different specifications.

Preferably, the adjusting mechanism comprises a portal frame 71 positioned above the oral liquid feeding conveying belt, and a plurality of blocking blocks 72 for blocking the channel dividing grooves are detachably arranged on the lower side of a cross beam of the portal frame. When the plugging block is removed, the corresponding lane dividing groove becomes an open lane dividing groove; when we install the plugging block, the corresponding shunting groove becomes a closed shunting groove. Of course, a transverse sliding shaft can be arranged on the lower side of the door-shaped frame, and the plugging block is connected to the sliding shaft in a sliding mode. The blocking block is moved to the corresponding lane dividing groove to block the lane dividing groove; or, the redundant plugging blocks can be moved to the two sides of the sliding shaft, so that the corresponding channel dividing grooves are opened.

As a preferable scheme, as shown in fig. 3, the bottle inverting mechanism includes a frame 21, and a bottle inverting roller 22 transversely disposed on the frame, the bottle inverting roller being associated with a stepping motor, two groups of circumferentially and uniformly distributed accommodating groove sets being disposed on a circumferential surface of the bottle inverting roller, each group of accommodating groove sets including a plurality of circumferentially and uniformly distributed cylindrical accommodating grooves 23 for accommodating packaging bottles, each accommodating groove corresponding to the lane dividing groove, so that the packaging bottles in the lane dividing groove can enter the corresponding accommodating groove. Furthermore, the axis of the accommodating groove is positioned in the tangential direction of the bottle inverting roller.

Thus, in step b, when the packaging bottles move to the tail end of the lane plate, the axes of the accommodating grooves of one group of accommodating groove groups are in a vertical state, and after the packaging bottles enter the accommodating grooves, the bottle inverting roller rotates slightly more than 90 degrees to enable the packaging bottles to be in a roughly flat state and slide into the bottle inverting conveyor belt to move forwards continuously. When the stepping motor drives the bottle inverting roller to rotate 180 degrees, the axis of the accommodating groove of the other accommodating groove group is in a vertical state, so that subsequent packaging bottles can rotate to a flat state.

Preferably, the rotation angle of the bottle inverting roller can be controlled between 95 and 110 degrees. Like this, when the cylinder of falling the bottle rotated, can make the packing bottle rotate to the state of front end downward sloping to the packing bottle is in the effect of self gravity from holding the recess roll-off and get into the conveyer belt of falling the bottle, avoids simultaneously when the cylinder of falling the bottle is not rotated in place yet, and the packing bottle is earlier from holding the recess and preceding roll-off.

As another preferable scheme, the carton feeding and conveying device comprises a carton feeding and conveying belt 41 for conveying upright packages, an equidistant conveying belt 42 for conveying flat packages, a box overturning mechanism 43 for converting the upright packages into the flat packages, and a box pushing mechanism 44 for pushing the upright packages to the box overturning mechanism.

In step d, the upright packing boxes which are stacked together in a bundle are moved forward along the paper box feeding conveyor belt to the box pushing mechanism, the box pushing mechanism pushes the upright packing box at the forefront transversely to the box turning mechanism, and the box turning mechanism rotates the upright packing box for 90 degrees and then moves forward flatly on the equidistant conveyor belt. The packaging boxes are conveyed forwards at intervals on the equidistant conveying belt, so that a follow-up box packing robot can accurately place the packaging bottles into the packaging boxes.

Furthermore, the packing box comprises a bottom box and a box cover, wherein one side edge of the box cover is connected with one side edge of the bottom box, so that the box cover can rotate around a rotating center, namely, the packing box is a book-shaped packing box. For this purpose, a cover opening mechanism 8 for opening the lid of the packing box is required, as shown in fig. 4 and 5, the cover opening mechanism comprises a lower sucker 81 for sucking the bottom box of the packing box, an upright frame, a mounting plate 82 arranged on the frame, a stepping motor arranged on one side of the mounting plate, a driving rod 83 arranged on the other side of the mounting plate, and a driven shaft 84, wherein a transverse output shaft of the stepping motor is connected with one end of the driving rod, one end of a driven rod 85 is connected with the driven shaft, the other end of the driving rod is rotatably connected with one end of a long connecting rod 86, the middle part of the long connecting rod is rotatably connected with the middle part of the driven rod, so that the driven rod is parallel to the driving rod, the other end of the driven rod is rotatably connected with one end of a short connecting rod 87, the other end of the short connecting rod is rotatably connected with one end of a box opening rod 88, and the other end of the box opening rod is rotatably connected with the other end of the long connecting rod, so that the short connecting rod is parallel to the long connecting rod, and the box opening rod is parallel to the driven rod. That is, the long connecting rod, the short connecting rod, the driven rod and the box opening rod are connected into a parallelogram structure; and the long connecting rod, the driving rod, the driven rod, the center of the output shaft of the stepping motor and the driven shaft are connected to form a parallelogram structure.

In addition, a box opening arm 89 is provided on the box opening lever, and a box opening suction cup 891 is provided on the box opening arm. In addition, the intersection point of the connecting line between the output shaft and the driven shaft and the extension line of the box opening rod is coincided with the rotation center of the box cover. The steps when the cover opening mechanism opens the cover of the packing box are as follows:

the lower sucker adsorbs and fixes the bottom boxes of the packing boxes on the equidistant conveying belt, and then the stepping motor drives the driving shaft to rotate in the positive direction, so that the box opening rod is driven to rotate synchronously through the long connecting rod, the driven shaft and the short connecting rod, and the box opening sucker on the box opening arm is attached to the box cover and adsorbs the box cover; the stepping motor rotates reversely, and then the box cover can be driven to rotate in the direction to be opened.

When the size specification of packing carton changes, that is to say, when the rotation center position of lid has the adjustment, we can conveniently adjust the position of rotation center through adjusting the position of mounting panel in the frame. Specifically, a vertical adjusting groove can be formed in the rack, a transverse adjusting groove is formed in the mounting plate, and a fastening screw is arranged at the intersection of the transverse adjusting groove and the numerical adjusting groove, so that the mounting plate is fixed on the rack. When the position of the mounting plate on the rack needs to be adjusted, the fastening screw can be loosened, then the mounting plate is moved up and down, and the position of the fastening screw in the vertical adjusting groove is changed; or the mounting plate is moved left and right, the position of the fastening screw in the transverse adjusting groove is changed, then the fastening screw is tightened, the position of the mounting plate can be adjusted, and the position of the rotating center is changed.

The stepping motor is connected with the box opening arm and the box opening sucker through the parallelogram connecting rod structure, so that an output shaft of the stepping motor can deviate from the box opening arm, the box opening sucker and the packaging box, the assembly is convenient, and the collision interference among the output shaft of the stepping motor, the box opening arm, the box opening sucker and the packaging box can be effectively avoided.

When the position of the mounting plate on the rack is adjusted, the positions of the box opening arm and the box opening sucker connected to the quadrilateral connecting rod structure need to be adjusted again to ensure that the box opening sucker can adsorb the proper position of the box cover, namely, the rotating radius of the box opening sucker needs to be adjusted. Because the driving rod, the driven rod and the box opening rod on the parallelogram connecting rod structure are always kept parallel, the rotation angle of the box opening sucker is equal to the rotation angle of the box opening rod, the rotation angle of the driving rod and the rotation angle of the stepping motor. Therefore, the rotating radius of the box opening sucker can be conveniently adjusted only by adjusting the included angle between the initial position of the driving rod and the long connecting rod, and meanwhile, the rotating angle of the stepping motor does not need to be reset, so that the use and the regulation are convenient.

In order to realize the equidistant transmission of packing carton that the long distance of packing carton was carried and ensure to keep flat packing carton, as shown in fig. 6, fig. 7, the equidistance conveyer belt includes equidistant transfer chain 421, connects the linking transfer chain 422 of equidistant transfer chain front end, the equidistant transfer chain includes by step motor driven two spacing hold-in ranges 423 about, and one of them spacing hold-in range goes up the interval and is equipped with a plurality of preceding spacing pieces 424, is equipped with the back spacing piece 425 that correspond with preceding spacing piece on another spacing band, form the interval that holds that matches with packing carton width size on the antedisplacement direction between preceding spacing piece and the back spacing piece that corresponds.

The link conveying line comprises a left link synchronous belt 426 and a right link synchronous belt 426 which are driven by a motor, the upper layer of the link synchronous belt is higher than the upper layer of the limit synchronous belt, and conveying guide rails 427 which are higher than the upper layer of the limit synchronous belt are arranged on the outer side of the limit synchronous belt at intervals.

Like this, in step d, the packing carton that is turned over into the state of keeping flat by turning over box mechanism gets into earlier and bears on two linking synchronous belts that link up the transfer chain and move forward, moves to the end that links up the transfer chain until the packing carton, and the packing carton falls into in the accommodation gap on two spacing synchronous belts in proper order this moment to form fixed interval between the messenger adjacent packing carton, two spacing synchronous belts antedisplacement about step motor drove, make the left and right sides sliding support of packing carton on the transport guide rail of the left and right sides.

Because the conveying guide rail is higher than the upper layer of the limiting synchronous belt, the left side and the right side of the packing box can be supported on the conveying guide rails on the left side and the right side in a sliding mode. That is to say, two preceding spacing piece on the spacing hold-in range of controlling, back spacing piece play the effect that makes the accurate location of packing carton on the one hand, and on the other hand starts the effect that promotes packing carton and move forward on conveying guide. Because the two sides of the packing box are supported on the conveying guide rail, the stability of the packing box can be ensured, the packing box manipulator can conveniently place the packing bottle into the packing box, the phenomenon that the packing box supported on the limiting synchronous belt is easy to shake left and right and up and down is avoided, and the accurate positioning of the packing box is facilitated.

It should be noted that, we can set up 2 or even many equidistant transfer chains and corresponding linking transfer chain according to the actual production needs to make linking transfer chain, equidistant transfer chain connect gradually. That is, the pack enters the front-most engaging conveyor line and then the subsequent equidistant conveyor line. Connect gradually through linking up transfer chain, equidistant transfer chain, both can realize the steady transmission of long distance of packing carton, can realize the equidistant transmission of packing carton again.

In addition, the conveying belt in the oral liquid feeding conveying belt extends to the lower part of the channel dividing groove; the conveying belt of the bottle-inverting conveying belt is also provided with a shunting groove, and the length of part of the shunting groove is shorter.
