Description

Technical field

The present invention relates to a rotary adhesive-edging machine operating in an intermittent (start-stop) mode of movement and intended for metal covers of large size and various shapes, having an average size and non-circular geometry, including oval, rectangular, square, etc.

The machine according to the invention is intended for combining adhesive and edge-bending operations in one device and closes a very specific market segment related to the production of medium / large format covers. It is important for the lid manufacturer to have a device in which the transition between different sizes can be made quickly and easily, taking into account that the need for large lids is much lower than for other, more standard lids.

In order to make such production profitable, downtime when changing the format should be reduced as much as possible. Therefore, a simple, practical machine with a simple transition between sizes has been developed. By combining edge bending and adhesive blocks in one device, the cost and space savings are significant.

In addition, by performing two operations without removing the lid from the machine, the time lost between the machines and the need to accumulate and stack the lids for one and the other operation are eliminated.

State of the art

Currently, there are various types of machines on the market that are adapted to perform the functions for which the machine of the invention is intended, but these actions are performed at a low speed (40/50 covers per minute) and are not combined in one unit. Until now, only one machine is known, specifically designed for the production of small format covers, and which is almost impossible to adapt for large sizes. Therefore, we are not aware of the existence on the market of glue-edge bending machines with non-circular geometry, adapted for such sizes of covers.

In this regard, this invention is intended to fill the gap in meeting the needs of manufacturers of caps.

Disclosure of invention

To achieve the goals and eliminate the disadvantages mentioned in the previous sections, the invention proposes an intermittent rotary adhesive-edging machine designed for large-sized and variously shaped metal caps, which has a prismatic geometry and is equipped with various drive means providing the devices required for flanging covers and applying glue.

In its upper part, it has an upper platform serving as a working table, mainly of a square shape and equipped in its center with a rotary discontinuous rotary disk for attaching covers and at least four substations, which are capable of processing over one hundred and fifty per minute covers up to 300 mm in size diagonally and more than two hundred and fifty per minute of covers with a diagonal of approximately 150 mm.

The number of substations will depend on the size of the cover, for example, as a guideline for medium-sized covers, the machine will have eight substations, and for large covers four. Four symmetric and interacting workstations that are located on the periphery of the disk with a 90 ° angle offset between each other, performing the process using a lid feeder, a hemming device, an adhesive device, and a lid removal device from the machine. Substations correspond to radial recesses or windows in a rotary disk into which covers are placed for moving in a circle by means of said disk.

To facilitate the synchronized action of the mechanisms, the rotary disk of the cover fastening is set in motion by a stepping mechanism, which informs it of intermittent movement, consisting of continuous turns of 90 °, 45 °, 22.5 °, etc. (depending on the number of substations) to move the cover from one station to another and stop to perform a specific operation: feeding, flanging, applying glue or removing covers from the device through the conveyor. The advance time and stop time at each substation are 50%, that is, at each substation, the time taken to turn a certain angle is the same as the stop time for flanging, applying glue, feeding or removing covers from the machine.

The four operating devices of the machine are 90 ° apart relative to each other on the periphery of the lid mounting disk. The order of operations performed on the covers is as follows: feeding, flanging, applying glue and transportation. In this process, the cover travels a total angular distance of 270 ° until it is removed from the machine. Each of the various processes performed over the lid is performed on a separate workstation.

Through the use of means for transmitting synchronized movements, the rotary disk of the lid fastening rotates with stops at four workstations to simultaneously perform various operations on the corresponding covers placed according to such workstations, while at least part of these work operations are also carried out by means of synchronized transmission with continuous movement .

Means of transmission of synchronized movements are based on a motor element that transmits its movement to the cam shaft, the rotation of which is transmitted to the stepper mechanism by means of a chain paired with the lower gear connected to the cam shaft and the upper gear connected to the side shaft of the stepper mechanism containing the upper shaft, transmitting movement to the rotary disk mounting the covers.

The edging device is characterized in that it contains the matrix holder body as a female element facing the punch as a male element, alternately moving up and down in the inner cavity of the matrix to form a cover by stamping, the punch moving by connecting with a crank mechanism that receives movement from the cam shaft.

The cam shaft is characterized in that it has a front eccentric tide, with which a front movable connection is fastened, articulated with a threaded end part of a threaded rod, pivotally connected at its free end to a cylindrical body part fastened to a base that is integral with the said punch.

On the other hand, the articulation between the threaded rod and the cylindrical body portion is a ball joint.

The reciprocating vertical movement of the punch is provided by at least two rods along which the base of the punch is guided, and which are connected at one of their ends to the upper platform serving as a working table.

The matrix holder housing is characterized in that it is retractable, for which it is connected to the transverse axis, and at the same time has a locking rod for fixing in the working position.

The fixing means for securing the matrix holder body includes a fixing rod with an extreme head part inserted into the inner socket of the matrix holder body, this fixing rod being connected to a gearbox provided with a fixing / releasing handle.

The glue device is characterized in that it comprises a copying mechanism defined by at least one carriage, including an injector of rubber material connected to parallel rods guiding its movement in the lower part and provided with at least one roller copier inserted in its groove in its upper part with a closed circuit corresponding to the trajectory of the outer groove of the cover, and the groove is made in the stationary main part of the copy cam located above the main pulley, including parallel w Angie and carriage.

The rotational movement of the adhesive device is transmitted from the servomotor through the main gear belt, coupled with the teeth of the main pulley and small pulleys connected along the perimeter connected to the side shafts.

Another difference of the invention is that the main pulley rotates the main shaft, mating in its upper part with a link operating without friction of rotation containing a reservoir for rubber material in a liquid state and connected to a distributor combined with nozzles including injectors and independently supplied with liquid rubber and air.

A cam groove is characterized in that it comprises an eccentric channel including three cam profiles: an upper profile acting as a cam, an intermediate profile acting as a counter-cam, and a lower profile also acting as a cam, with the eccentric channel being added by three copier rollers, so that the upper and lower rollers abut against the inner surfaces of the upper and lower cam profiles, while the intermediate roller comes into contact with the outer surface of the intermediate cam profile.

The adhesive device assembly is moved upward by means of a rear lifting assembly comprising a linear drive for pulling the adhesive device connected to the vertical guides.

It should be understood that the injectors of rubber material and roller copiers are placed in the same vertical direction.

The lid removal device includes a pusher with a vertical reciprocating movement that moves the lid upward from its position in the radial recess or the window of the rotary disk, and also includes a magnetic conveyor belt coupled to the pulleys to remove the lid from the machine when its processing is completed.

The reciprocating movement of the pusher is provided by a crank mechanism driven by a cam shaft.

The mentioned crank mechanism, creating a reciprocating movement of the pusher, is determined from an external eccentric tide, with which the lower swivel joint is articulated, fastened to a shaft connected in turn at its free end to another movable joint, fastened to the pusher, guided by vertical barbells.

The feeding device is characterized in that it includes a rack as a hopper for feeding covers located one above the other and facing the corresponding radial window of the rotary disk, the base of this rack containing, as a bottom and a holder for covers, upper supports and lower supports installed in different planes and connected to the drive units, the actuation of which causes the antidirectional and simultaneous linear displacement of the upper supports in relation to the lower supports and vice versa.

The machine also includes a front lifting unit, vertically moving along two guides, the feeder assembly of the covers under the action of a linear drive.

The machine also contains a group of magnets under the rotary table for attaching the covers, radially located inside the chambers and designed to fix the covers.

Further, in order to facilitate and better understand the above description and as an integral part of it, the drawings are shown, which reflect the essence of the invention, given by way of illustration, and not to limit the scope of the invention.

The implementation of the invention

When considering the drawings, it can be noted that the invention relates to a glue-edging machine 6 for metal covers 56 of non-circular geometry, the main difference of which is the simultaneous execution of glue and flanging operations in one unit due to the use of medium / large sizes and any form of glue for covers 56 devices 4 and hemming devices 3, adapted to be adapted due to the simple and quick change in the size of the rotary disk 1 for fixing the covers, stamp 16-17, copy copy Single flow racks 63 and 12. The rotary disc 1 is situated above the upper platform 51 serving as a desk.

The movement of various mechanical gears of the glue-edging machine begins with the main drive motor 9, which, due to the toothed drive belt 10, provides movement of the cam shaft 11, which, in turn, is responsible for performing independent movements of the following nodes: rotary disk 1 for attaching covers, stamp 16-17 pusher 40 and cover removal device 5.

The central node of the glue-edging machine 6 is an intermittently rotatable lid mounting disk 1, equipped with at least four substations for installing lids 56 and distributing them to various stations with machine devices. It is driven by a stepping mechanism 8, providing intermittent forward rotation and stopping, the forward movement being used to move cover 56 from one station to another station, and stopping the movement to apply the various actions described below. The movements of the various components of the machine and the rotary disk of the cover fastening are synchronized, so that all the stations act in concert.

The device 2 feed covers consists of a rack 12, acting as a hopper for the accumulation of covers 56 and feeding them to the rotary disk mounting lids. The assembled covers are separated from one another and placed in the substation of the rotary disk 1 (radial recesses or windows 61 into which the covers 56 are installed), while the corresponding radial recess 61 is located directly under the rack 12 with two nodes. One of them consists of an upper support 13, a lower support 14 and a pneumatic clamp 15. The other assembly consists of two upper supports 13, two lower supports 14 and a pneumatic clamp 15.

Each support moves linearly, being individually mounted on each of the two radial carriages provided on the clamp 15. These nodes are located at the bottom of the feed rack 12 and on opposite sides, therefore providing uniformly distributed fastening of the covers 56 at three contact points to thereby eliminate vibration rack covers 12.

First, the covers lie on the upper support 13, partially entering the inner part of the rack 12. Due to the pneumatic action of the clamp 15, the upper 13 and lower 14 supports simultaneously move in opposite directions, so that when the upper support leaves the plane inside the rack 12, the lower support 14 moves inward this plane.

In this way, the accumulated covers 56 fall onto the lower support 14, which acts as a latch. After this, the new cycle of action of the pneumatic gripper 15 leads to the reverse movement of both supports, changing their roles, so that the upper support 13 is pushed into the rack 12, while the lower support 14 moves in the opposite direction, providing individual lids 56 to the rotary disk 1 of the lid attachment , on which, thanks to the radial arrangement of the magnets 47 placed on the table 51, the covers 56 are fixed in the substation for further movement by the rotary disk 1.

To simplify the adjustment, installation and execution of work on changing the size, a device 2 for supplying covers with a lifting unit 48 is provided, which greatly facilitates these operations. This assembly of the cover feeding device 2 moves vertically along two linear guides provided with bearings under the action of a pneumatic cylinder not shown in the drawings, as well as linear guides. All of these elements are fastened to the lifting unit 48.

As for the resizing, it will only be necessary to replace the feed rack 12 with another, the geometry of which corresponds to the size of the installed cover.

The operation of bending the edge is performed by applying pressure using a stamp 16-17. It consists of two conjugated main parts, one fixed, with a female profile, the so-called matrix 16, and another movable main part with a male profile, the so-called punch 17. The edge of the lid 56 is bent in one pass by applying the force developed by clamping in the inner cavity of the stamp 16-17, leading to the formation of a shelf. This method provides excellent flanging, ending with editing the border of the lid and thus contributing to its final entry into the package.

The vertical movement of the punch 16 up and down is created due to the connecting crank mechanism. The cam shaft 11 has at its end a front eccentric tide 54 provided with a movable joint 18, which includes a threaded rod 19 with a spherical end. The upper end of the threaded rod 19 is inserted inside the cylindrical main body 20 having a spherical cavity and thus forming a new hinge. The cylindrical part 20 is screwed to the base 21 of the punch 17, so that when the cam shaft 11 rotates, the rotation of the front eccentric tide or protrusion 54 causes the threaded rod 19 to move up and down, which in turn pushes the punch 17 to the boundary position corresponding to the location of the matrix 16.

To ensure strict vertical movement of the up and down punch 17, the main part 21 of this punch 17 is guided by at least two rods 22 located on it. Similarly, the matrix 16 is fixed in the housing 23 of the matrix holder, made with the possibility of removal for installation operations and provided on its lower base with a lower socket 58, which includes a locking rod 24, driven by a one-sided handle 26 through a gearbox 25 to fix / release the device .

With such a fixation system, there is confidence that, with the pressure applied to the die 16 during the stamping process, complete immobility is ensured, guaranteeing an impeccable completion of the bending of the edge of the lid. In this embodiment, to change the size of the cover, it is only necessary to replace the die 16 and the corresponding punch 17 with others corresponding to the new geometry of the cover installed in the machine. Therefore, the process is quick and easy to execute.

The head portion 24 of the fixation rod is included in the internal socket 58 of the housing 23 of the matrix holder, and the housing 23 of the matrix holder is pivotally connected to the transverse axis 57 to retract it.

The new adhesive device 4 performs its operation by applying liquid rubber directly to the peripheral groove 60 of the cover 56 at a certain flow rate through the injector 27 of the nozzle 28 adapted to perform this operation. The basis of the adhesive device is the mechanism 63 of the copy cam and the roller copier 31, which however have interesting distinctive properties and advantages described below.

This operation begins with a stationary disk copy cam 63 provided with a groove and a roll copier 31 moving with its profile inside the channel or groove 62 having a closed loop. Roller copier 31 consists of three angular contact bearings. To ensure constant contact, the copy cam 63-31, the eccentric groove 62 is made up of three profiles (internal “cam” profiles 29-29 ′ and an external “cam” profile 30). The connection of the three roller copiers 31 is made in such a way that the bearings are forced to be pressed at three contact points opposite each other, so that two of them rest on the inner cam profiles 29-29 ′, while the other is in contact with the outer profile of the so-called counter-cam 30 With such profiles of the cam and counter-cam 30, the channel, which is slightly larger than the roller of the roller copier 31, is machined, and its center passes along the axial line of the groove 62.

When using three rollers in a roll copier 31 in combination with a groove 62 having a closed contour and an eccentric, play and errors in copying the cam profile 29-29′-30 are eliminated, which creates an effective replacement for the double-sided disk cam mechanism with the advantage that in this In this case, it is possible to save on the cost of manufacturing a cam and a copier.

With this design, it is possible to guarantee that at all 360 ° of rotation, the roller copier 31 will reliably and accurately follow the cam profiles 29-29′-30, in contact with them with uniform pressure all the way. In the developed copying mechanism, it is worth noting that the geometric center of the roller copier 31 moves along the cam-counter-cam-cam 29-30-29 ′ contour, identical to the path traveled by the center of the nozzle 28 along the peripheral groove 60 of the cover 56, which can be confirmed by the fact that the centers of the roller the copier 31 and the nozzle 28 are on the same vertical.

During processing, the lid is stationary, and two nozzles 28 move above it, following a given cam profile 29-29′-30. The movement of the adhesive device 4 is triggered by a servomotor 32, which, through a transmission including the main belt 64 and the small pulleys 65, signals the movement of the main pulley 33. The small pulleys 65 are mounted on the side shafts 66.

The main pulley 33 encloses a carriage 34, placed in a longitudinal groove 34 and serving as a connection between the roller copier 31 and the nozzle 28, and its movement is guided by two rods 35 mounted parallel and symmetrical to the center of the main pulley 33. When it rotates, the roller copier 31 moves along the groove 62 of the cam 29-29′-30, informing the carriage 34 linear movement along the guide rods 35 and turning it when the main pulley 33 rotates. The groove 62 passes in the copy cam 63 and includes three cam profiles cam-cam 29-30-29 ′, hairstyle itself copying cam 63 is located above the main pulley 33.

Thus, by combining with the carriage 34, the nozzles 28 also linearly move along with the rotation. Therefore, copying of the cam profile 29-30-29 ′ is achieved, which in this case coincides with the center of the peripheral groove 60 of the cover 56, on which the adhesive is applied.

The results obtained with such a system based on copying with a triple contact cam-copier are very satisfactory, since with one copy cam 63 and a roller copier 31 a system free of backlash and torque is guaranteed, which guarantees reliable and accurate profile copying and longer service life of copiers.

The supply and distribution of the filler material (liquid rubber) to the glue / edge bending machine is carried out through the acting without friction rotation link 7 located at the top of the glue device 4. It includes a reservoir 36 connected to the distributor 37 through the main shaft 38 of the glue device. This main shaft 38 has two holes for supplying air and rubber, which in turn branch into four inputs when the distributor 37 is reached. Through this distributor, rubber and air are independently supplied to the nozzles 28.

To facilitate adjustment, installation and resizing, the adhesive device 4 is provided with a lifting unit 39 located at the rear, which greatly facilitates these operations. The adhesive device 4 is vertically moved along two linear guides provided with bearings, under the action of a pneumatic cylinder, not shown in the drawings, as well as linear guides.

It is interesting to emphasize the simplicity and speed with which the change in the size of the cover can be made, for which you only need to replace the copy cam 63 with another one suitable for the new cover installed in the machine.

The lid removal device 5 performs a synchronized removal of the lids from the machine to the drying oven. Such a removal device 5 mainly comprises two elements: a pusher 40 and a belt 41 of a magnetic conveyor with pulleys. The pusher 40, made with the possibility of vertical reciprocating movement, lifts the cover from the corresponding substation (radial recess 61) of the rotary disk 1, bringing it closer to the removal device 5. Due to the magnetic field created by the aforementioned removal device 5, the lid is attracted to the evacuation belt 41, fastened to it to be removed from the machine.

The vertical reciprocating movement of the pusher 40 is carried out by a crank mechanism driven by a cam 42 located at the end of the cam shaft 11. The cam 42 formed by the rear eccentric tide and the pusher 40 are fastened together by a rod 43 having the upper 44 and lower 44 ′ movable joints at their ends. When the cam shaft 11 is rotated, the rear eccentric tide 42 rotates, causing the pusher 40 to move vertically through the vertical movement of the stem 43 and the movable joints 44-44 ′, in which the cover is lifted from the rotary disk substation 1 to the magnetic conveyor belt 41.

The movement of the pusher 40 is guided by vertical rods 55.

The cover removal device 5 is provided with a group of magnets that create a magnetic field and attract the cover, preventing it from coming off the conveyor belt 41. In addition, the removal device 5 is driven through a gearbox 45 with a ratio of 1/1, which receives movement from the kinematic chain 50, moved by the lateral output shaft 46, extending on the right side of the stepping mechanism 8. This part of the machine is not subject to any changes before a possible change in the size of the cover.

The engine element 9 transmits its movement to the camshaft 11, and the rotation of the latter is transmitted to the stepping mechanism 8 by a chain 50 coupled to the lower gear 53 connected to the cam shaft 11 and the upper gear 52 connected to the side shaft 46 of the stepping mechanism 8, including the upper shaft 49, which reports the movement of the rotary disk 1 mounting the covers.
