Description

Technical Field

[0001] The invention relates to the field of packaging machinery and equipment, in particular to an auxiliary device for a blister packaging production line, and more particularly to a roll receiving device for a blister packaging production line. Background Art

[0002] The main part of the blister packaging production line of the existing technology is the blister packaging machine, which mainly includes four devices: blistering, blanking, packaging and punching. Specifically, the blank film reel unwinding will form a strip blank film. The blistering device is responsible for pulling the head end of the strip blank film, pulling it into the blistering device to heat it to soften it, and using vacuum negative pressure suction or high-pressure air blowing to produce blisters, that is, the heated and softened strip blank film is made into a strip-shaped molding film with multiple blisters, and continues to be transported forward to the blanking device; the blanking device is responsible for automatically transporting the packaged particles (generally pills) to fill the corresponding blisters on the molding film; the packaging device is responsible for covering the strip-shaped covering film on the surface of the strip-shaped molding film, and heat-sealing or gluing the covering film and the molding film to form a strip-shaped packaging film, so as to seal the pills in each blister corresponding to the packaging film; finally, the punching device cuts the strip-shaped packaging film encapsulating the pills into multiple small unit plates in sections.

[0003] For the convenience of expression, the blank film reel of the present application will be referred to as a reel in the subsequent text.

[0004] The present application relates to a front auxiliary device on a blister packaging production line, which functions as a reel. Specifically, in the prior art, the reel is suspended on the shaft of the unwinding station. After the worker manually pulls out the strip of blank film from the reel, the head end of the blank film is pulled into the range of the blistering device, and is clamped and wrapped by the relevant mechanism in the blistering device, and pulled into the blister packaging machine for subsequent processes such as blistering, unloading, and packaging. However, in the prior art, whenever the blank film of the old reel is pulled out and only the inner lining tube is left, a worker is required to temporarily fix the rear section of the blank film with a quick pressing clamp, and because the tail end of the blank film was originally bonded to the inner lining tube, after the tail end of the blank film is forcibly pulled off the inner lining tube, it will be uneven and bonded with paper scraps of the inner lining tube, so a worker is also required to cut off the tail end of the blank film to form a smooth fracture; then the worker removes the inner lining tube of the old reel from the shaft of the unwinding station, picks up the new reel and replaces it on the shaft of the unwinding station, then pulls out a strip of new blank film from the new reel, and pulls the head end of the new blank film over the fracture of the old blank film and covers the rear section of the old blank film, then manually presses down the hot pressing plate to heat-seal and bond the overlapping parts of the new and old blank films, then releases the hot pressing plate pressing the overlapping parts and the quick pressing clamp pressing the rear section of the old blank film, and the reeling is completed at this time.

[0005] Two concepts need to be clarified here, namely the tail end and the rear section of the blank film. As the name suggests, the tail end refers to the last end of the blank film, and the rear section refers to a short distance in front of the tail end.

[0006] The above existing technology has a low degree of automation in the coiling process and relies entirely on manual operation. The steps are complicated, the speed is slow, the time is long, the efficiency is low, and it is easy to make mistakes. Moreover, a special person is required to manually coil the coils, which has high labor costs and poor economic benefits. Moreover, in the coil changing process before coiling, each new coil generally weighs more than 20 kilograms, and the process of workers carrying and changing the coils is also relatively laborious. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a reeling device for a blister packaging production line which can automatically and firmly connect the head end of a new blank film of a new reel with the rear end of an old blank film.

[0008] The technical solution of the present invention is to provide a reeling device for a blister packaging production line, which includes a frame, a horizontal partition is installed on the frame, and a driving shaft driven by a reeling motor is arranged above the horizontal partition; a front hinge seat is fixed on the upper surface of the horizontal partition, and a front inclined pressure plate is hinged on the front hinge seat; the driving shaft drives the sleeved reels to unwind to form a strip-shaped blank film, and an air pipe nozzle for blowing the blank film to the front inclined pressure plate is also arranged above the horizontal partition;

[0009] The frame is also fixed with a coil receiving platform connected with the transverse partition; the coil receiving platform is rotatably equipped with a pair of active pressing rollers for clamping and pulling the blank film blown over the front inclined pressing plate, and the pair of active pressing rollers are driven by a stepping motor;

[0010] The reeling platform is also equipped with three downward pressure cylinders, front, middle and rear. The piston of the front downward pressure cylinder is provided with a front pressure plate for pressing the tail end of the old blank film after the old reel is unwound; the piston of the rear downward pressure cylinder is provided with a rear pressure plate for pressing the rear section of the old blank film after the old reel is unwound; the reeling platform is hollowed out with a knife slit parallel to the front pressure plate, and a knife blade for cutting off the tail end of the old blank film pressed by the front and rear pressure plates is slidably matched in the knife slit, and the knife blade is driven by the cutting cylinder; the reeling platform is provided with a waste opening for discharging the cut part of the old blank film on the table surface below the front pressure plate, and the waste opening is provided with a valve driven by a rotating cylinder;

[0011] Replace the new reel and unwind to form a new blank film. The head end of the new blank film passes over the fracture of the old blank film and covers the rear section of the old blank film under the blowing of the air pipe nozzle and the clamping of the active pressure roller, and is pressed by the front pressure plate; the pistons of the middle and lower pressure cylinders are provided with hot pressing plates for hot pressing and bonding the overlapping parts of the new and old blank films.

[0012] Compared with the prior art, the roll-taking device adopting the above structure has the following advantages.

[0013] First analyze the working process of the device.

[0014] The normal unwinding process is that the unwinding motor drives the nested reels to rotate through the active shaft of the unwinding station, unwinding the strip of blank film, and the strip of blank film is moved close to the front inclined pressure plate under the blowing of the air pipe nozzle above the diaphragm. Then the strip of blank film is pressed down by the front inclined pressure plate and guided into the gap between the front inclined pressure plate and the upper surface of the diaphragm. In other words, the head end of the blank film moves forward along the upper surface of the diaphragm until it reaches the range of the active pressure roller, and is clamped and engulfed by the active pressure roller to continue moving forward, and is transported to the inside of the blister packaging machine of the blister packaging production line for subsequent processes such as blistering, unloading, and packaging.

[0015] When the old reel is unwound, that is, the tail end of the old blank film is torn off from the inner lining tube of the old reel, the front pressing plate and the rear pressing plate are pressed down at the same time to press the tail end and the rear section of the old blank film respectively, and then the blade is driven to cut off the tail end of the old blank film to form a smooth fracture, and then the front pressing plate is lifted and the valve is rotated to allow the cut part of the old blank film, that is, the tail end of the old blank film, to be discharged from the waste outlet.

[0016] The inner liner tube is removed manually or automatically and the new reel is put on the driving shaft of the unwinding station, and the unwinding motor is driven to unwind to form a new blank film. The head end of the new blank film is blown by the air pipe nozzle and clamped by the active pressure roller, and is pulled over the fracture of the old blank film and covers the rear section of the old blank film. The front pressing plate is pressed down again to position the head end of the new blank film, and the hot pressing plate is pressed down to heat-seal and bond the overlapping parts of the new and old blank films. After the new and old blank films are firmly heat-sealed, the three pressing plates are lifted upwards, and the reeling is completed. The active pressure roller continues to transport the extended strip blank film to the inside of the blister packaging machine of the blister packaging production line.

[0017] From the above analysis, it can be seen that the device can completely replace manual labor and automatically complete the function of firmly connecting the head end of the new blank film of the new reel with the back end of the old blank film; and compared with manual splicing, the mechanical splicing action is fast, efficient and accurate, with a low error rate; it reduces labor costs and labor intensity, and improves economic benefits.

[0018] As a gain, the frame is rotatably mounted with a turntable, the cross partition is fixed in the middle of the turntable, and the driving shaft is rotatably mounted on the turntable; the driving shaft, unwinding motor, front hinge seat, front inclined pressure plate and air pipe nozzle, which are also located above the cross partition, constitute a set of unwinding components; another set of the same unwinding components is also arranged under the cross partition;

[0019] The device also includes a slideway with a high front and a low rear, on which a row of continuous reels are placed, and at the end of the slideway are provided a first stop fork for blocking the first reel and a first locking cylinder for driving the stop fork;

[0020] When the reel above the diaphragm has been unwound and only the inner liner is left, the turntable rotates 180 degrees, so that the driving shaft with the inner liner reaches the reel changing station;

[0021] The frame is also provided with a discharge arm for grabbing the inner liner tube located at the coil changing station;

[0022] The device also includes two cantilevers for supporting the reel that falls from the slide and a slide cylinder for pulling the cantilever backwards, each cantilever is provided with a hook at the front end, and each cantilever is connected to the slide of the slide cylinder at the rear end; the frame is also provided with a lifting platform for installing the slide cylinder; the lifting platform is provided with a lifting component for adjusting the height of the cantilever to ensure that the center hole of the reel supported by the cantilever is aligned with the axis of the driving shaft of the reel changing station.

[0023] The gain portion of the device operates as follows.

[0024] When the reel above the diaphragm is unwound and only the inner liner is left, the turntable rotates 180 degrees to make the inner liner reach the reel changing station; then the unloading arm is driven to remove the inner liner on the driving shaft of the reel changing station. At this time, the old reel is automatically disassembled.

[0025] Before the old reel is unwound, the first position cylinder lowers the first fork, so that the first reel on the slide slides out of the slide under its own weight and falls onto the two cantilevers; then the lifting assembly moves to adjust the cantilever height to ensure that the center of the reel supported by the cantilever is aligned with the axis of the driving shaft of the reel-changing station; then the slide cylinder is driven to pull the reel backward through the cantilever and hook, so that its center hole is tightly sleeved on the driving shaft of the reel-changing station. When the old reel above the diaphragm is unwound and the turntable rotates 180 degrees, the new reel that has been tightly sleeved under the diaphragm will rotate synchronously to the unwinding station above the diaphragm to start a new round of unwinding. At this time, the new reel is automatically replaced and reaches the unwinding station.

[0026] From the above analysis, it can be seen that the gain part of the device can automatically remove the old reel that has been unwound from the unwinding station, and automatically replace the new reel to the unwinding station; there is no need to rely on manual handling of the heavy new reel, which reduces labor intensity and realizes full automation of the reel changing and rewinding process. Therefore, the factory completely saves the labor at the front station of the blister packaging production line, reduces labor costs, and improves economic benefits.

[0027] Preferably, a second fork for blocking the second reel and a second positioning cylinder for driving the fork are also provided at the end of the slide; the second fork and the first fork are used in combination with each other. Specifically, when the first fork falls and the second fork rises, the first reel falls out of the slide, while the second and subsequent reels are blocked. The purpose of this action is to block the pushing of the first reel by the reels above, ensure that the first reel falls smoothly to the cantilever, avoid the situation where the first reel falls out of the cantilever due to excessive pushing from the upper part, and improve the movement accuracy and stability; after the first reel falls out of the slide, the first fork rises and the second fork falls, and the subsequent series of reels move downward the distance of one reel to achieve filling.

[0028] The power input of the turntable part is preferably that two upper and lower brackets are fixed on the rear surface of the turntable, and the two unwinding motors of the two unwinding assemblies are respectively fixed on the two brackets, and the first output gear of each unwinding motor is meshed with the transmission gear on the driving shaft of the same unwinding assembly; the frame is fixed with a bow-shaped frame with an opening facing forward via a tripod, and a transposition motor is fixed on the upper beam of the bow-shaped frame, and an inner gear ring is provided in the center of the turntable, and the second output gear of the transposition motor is meshed with the inner gear ring; in this way, firstly, it is ensured that the power input of the two driving shafts and one turntable is continuous and stable; and the hollow inner gear ring in the middle of the turntable combined with the eccentric input method saves the material in the middle of the turntable and reduces the cost of the turntable; and the backward bending design of the bow-shaped frame not only ensures that the suspended transposition motor is installed firmly and reliably, but also just makes room to avoid the bracket and the unwinding motor rotating with the turntable, so that the various transmission components can operate in coordination with each other without interfering with each other.

[0029] The connection structure of the turntable and the frame is preferably that the frame is rotatably mounted with a circle of multiple mounting wheels, each mounting wheel is provided with a wheel groove, the outer circumference of the turntable is provided with an annular convex strip, and the annular convex strip is accommodated in each wheel groove of the circle of mounting wheels; the wheel grooves of the above-mentioned circle of multiple mounting wheels have an ideal effect on the straightening and centering of the turntable, and can ensure that the rotatable connection between the turntable and the frame is firm and stable. In this way, the process of eccentric torque transmission can be ensured to be smooth and stable. Otherwise, only a large rigidity, large torque, large size motor and a thicker central transmission shaft can be used to input torque from the center of the turntable; therefore, after solving the problem of rotatable connection between the turntable and the frame, the turntable can be hollowed out to save middle materials, and small-sized, small rigidity, small torque, cheaper transposition motor and small-sized transmission shaft can be selected for eccentric transmission, which can significantly reduce the cost while ensuring stable transmission.

[0030] The connecting structure of the mounting wheel and the frame is preferably that the rear section of the wheel axle of the mounting wheel is a small diameter section with a thread, and a step surface is formed between the normal section of the wheel axle and the small diameter section; the frame is provided with long through holes corresponding to the mounting wheels one by one, and each long through hole extends radially along the turntable; the small diameter section passes through the long through hole and is screwed with a locking nut; in this way, tightening the nut makes the step surface of the wheel axle press against the orifice of the long through hole, thereby quickly realizing the positioning of the wheel axle of the mounting wheel, and loosening the nut can quickly unlock the wheel axle, so that the position of the mounting wheel can be freely adjusted along the long through hole, that is, the radial direction of the turntable; in this way, the positions of the mounting wheels at the lower part of the turntable are first fixed, and then the lower part of the turntable is clamped and supported on the mounting wheels that have been clamped at the lower part, and finally, the remaining upper mounting wheels are moved radially inward, so that the wheel grooves of the upper mounting wheels clamp the annular convex strips of the turntable, and then the nut is tightened to lock the wheel axle position of the upper mounting wheel; in summary, the turntable can be quickly and conveniently installed on the frame and the rotatable connection relationship between the turntable and the frame is firm and stable.

[0031] The above three features cooperate and complement each other. Only by using a wheel axle with a nut and a step surface can the large turntable be clamped in the wheel groove of each mounting wheel quickly and conveniently, and the radial position of each mounting wheel can be flexibly adjusted, so as to flexibly adjust the radial limited clamping degree of each mounting wheel to each point of the turntable to ensure that the turntable is centered and firmly and reliably connected to the frame for rotation; in this way, the equipment foundation and premise can be provided for the eccentric input of power; and only by achieving stable and reliable eccentric input can a series of advantages be derived, such as hollowing out the center of the turntable to save materials, selecting small-power and small-size transposition motors and drive shafts, and thus significantly reducing the cost while ensuring stable transmission.

[0032] The connection structure between the cantilever and the slide cylinder is preferably that a connecting beam is fixed on the slide of the slide cylinder, and the two ends of the connecting beam are respectively fixed to the rear ends of the two cantilevers, and two sliders are respectively fixed at the two ends of the connecting beam, and the lifting platform body is provided with two slide rails parallel to the cantilever, and each slider is slidably matched on the slide rail on the same side; the lifting platform body is also provided with two reinforcing beams, each reinforcing beam is provided with a guide groove, and a supporting beam is slidably matched in each guide groove, and each supporting beam is fixed to the cantilever on the same side through an angle steel; first, the two cantilevers are fixed to the connecting beam, and the two ends of the connecting beam are slidably matched with the two slide rails through two sliders, so that The cantilever provides strong guidance, ensuring that the process of the slide pulling the cantilever backward is stable, smooth and reliable, and effectively improving the movement accuracy of the new reel being squeezed into the driving shaft of the reel changing station; moreover, each cantilever is connected to a support beam via an angle steel, and the support beam also slides in a guide groove parallel to the cantilever, and the support beam can effectively support the cantilever, thereby improving the strength and rigidity of the cantilever and preventing its cantilevered end from deforming and sagging under the load of the reel; in this way, it is ensured that the two cantilevers can firmly support the reel without the need to use a whole support plate, which vacates the area between the two cantilevers, making it easier for the unloading arm to discharge the inner liner of the old reel from the gap between the two cantilevers.

[0033] The unloading arm preferably includes an x-direction cylinder fixed on the frame, a y-direction cylinder fixed on the piston of the x-direction cylinder, and an air claw fixed on the piston of the y-direction cylinder; the arm drives the air claw along the y-direction to cover the inner liner of the roll changing station, then grasps the inner liner, and then moves the air claw along the x-direction to make the inner liner reach between the two cantilevers, releases the air claw to make the inner liner fall, then retreats along the x-direction, and finally retreats along the y-direction. It is precisely because the strength and stiffness of the two cantilevers are ideal and there is no need to select a solid support plate, so there is enough space between the cantilevers for the unloading arm to unload materials; in this way, only x-direction and y-direction movement are required to realize the unloading and resetting process, which simplifies the structure of the unloading arm to the greatest extent and further reduces the cost.

[0034] As a further preferred embodiment, the frame chassis is provided with a lifting motor, and the lifting motor is connected to a vertical screw through a corner reduction box, the threaded hole of the lifting platform body cooperates with the screw, and the four corners of the lower surface of the lifting platform body are provided with four guide columns and the frame chassis is provided with four guide sleeves, and each guide column is slidably sleeved in the corresponding guide sleeve; two infrared sensors are provided at the 0 o'clock position and the 6 o'clock position of the front end face of each driving shaft, and the winding device also includes a PLC chip, and the infrared sensor and the lifting motor are both connected to the PLC chip signal. First of all, the ball screw pair operates firmly and reliably as a lifting device; and, as the platform body of the lifting platform rises, if the upper and lower infrared sensors of the active shaft of the reel changing station do not receive a rebound signal, it means that the active shaft is just facing the center of the new reel, so the alignment result is reported to the PLC, the lifting is stopped, and the height of the reel is locked to ensure the accuracy of the action of pulling the reel into the active shaft of the reel changing station to avoid jamming.

[0035] As a further preferred embodiment, a ratchet pawl structure is provided between the driving shaft and the transmission gear to ensure that the torque is output unidirectionally from the transmission gear to the driving shaft; during normal unwinding, when the strip-shaped blank film passes over the front inclined pressure plate and the rear inclined pressure plate and is clamped by the active pressure roller, since the stepper motor of the active pressure roller is faster than the unwinding motor, once the blank film is clamped by the active pressure roller, the unwinding motor will stop immediately. This is to avoid the unwinding motor from stopping in time or restarting unexpectedly after stopping, thereby affecting the precise feeding speed of the blank film; it also avoids the torque of the stepper motor from being reversely transmitted to the unwinding motor through the blank film, which protects the unwinding motor.

[0036] The connection relationship between an upper active pressing roller and a winding platform is preferably that the winding platform is provided with two left and right first guide frames, a tensioning cylinder with a piston downward is installed on the first crossbeam of each first guide frame, an axle seat is fixed on the piston of each tensioning cylinder, each axle seat is slidably matched with the first column of the first guide frame on the same side, and the two ends of an upper active pressing roller are rotatably matched with the left and right axle seats respectively; in this way, the height of the two axle seats on both sides can be effectively adjusted by synchronously extending and retracting the two tensioning cylinders on both sides, thereby adjusting the height of the upper active pressing roller, and then adjusting the spacing between the two active pressing rollers in the same group, that is, the degree of clamping of the strip blank film, to adapt to different batches of blank films of different thicknesses, and ensure that the active pressing roller can always clamp the blank film and step accurately.

[0037] The mounting structure of each pressing plate is preferably such that each pressing cylinder is connected to the roll receiving platform via a second guide frame; the cylinder body of each pressing cylinder is fixed on the second crossbeam corresponding to the second guide frame; the piston of each pressing cylinder is fixed with a sliding beam, and the sliding beam is slidably matched with the second column of the corresponding second guide frame; a guide rod is fixed on the pressing plate of each pressing cylinder, the upper end of the guide rod passes through the corresponding sliding beam and a nut is screwed on the upper end of the guide rod, a compression spring is sleeved on the guide rod, and the two ends of the compression spring are respectively pressed against the corresponding sliding beam and the pressing plate; first, the sliding beam and the second column are fixed The design of column sliding fit can ensure that the vertical downward pressing action of each pressure plate is smooth and stable; moreover, the pressure plate is connected to the sliding beam via a compression spring. Under normal conditions, the compression spring is stretched, and the pressure plate is hooked on the sliding beam via a guide rod and a nut. When the pressure plate is pressed downward, there will be an elastic compression buffering process, that is, as the sliding beam descends, the pressure plate first contacts the blank film, and then the pressure increases continuously, and finally the blank film is compressed; the process of buffering and elastic compression of the blank film can effectively protect the blank film, and avoid the blank film being crushed or even broken due to excessive downward pressure and direct rigid contact with the blank film.

[0038] As a further gain, a rear hinge seat is fixed on the table surface of the roll-joining table located in front of the active pressure roller, and a rear inclined pressure plate is hinged on the rear hinge seat; a pair of driven pressure rollers are provided on the table surface of the roll-joining table located behind the rear downward pressure cylinder; the presence of the rear hinge seat and the rear inclined pressure plate can further press down the blank film, making it closer to the upper surface of the roll-joining table, which is conducive to the blank film being accurately clamped and wrapped by the active pressure roller, further improving the accuracy of the roll-joining operation; and the driven pressure roller added behind the rear downward pressure cylinder makes the blank film after joining the roll more smoothly, more smoothly and more stably transported to the inside of the blister packaging machine of the blister packaging production line, further ensuring the normal and stable progress of subsequent blistering, unloading, packaging and other processes.
