Description

Packing and unpacking machine for bottles and the like.

The innovation relates to a packing and unpacking machine for bottles and the like. With horizontally displaceable over the vessels Carrier trolleys and associated vertical lifting devices for the holding frames equipped with packing heads. It is already known to arrange a carrier carriage over the vessels and to seem to move it back and forth on a horizontal path

on

ben. It is also known / this carrier trolley vertical lift cylinder to be provided as lifting devices for the bottle holder frame. So while the carrier trolley is making horizontal movements, the lifting cylinders arranged on the carrier carriage convey the vertical component of the movement for the bottle holder frame. the The entire conveyor track for the holding frame is therefore made up of the horizontal and the lifting cylinders conveyed by the carrier trolley mediated vertical component composed and can be completely as desired according to the local conditions in their Shape to be determined.

It is also already known to provide separate lifting paths for the forward and return of the bottle holder frame, so that one loop-like conveyor track for the bottle holder frame comes about.

The vertical movement of the holding frame is usually not neglected borrowed and, accordingly, require beyond the carrier car stationary lifting cylinder for the vertical movement a considerable height of the machine; it also creates a closed construction

wisely prevented.

The task of the innovation is now to create a device with which the holding frame on its hook-shaped trajectory without any gear units protruding upwards or to the side that increase the overall height or overall length of the machine and can be guided without machine parts provided in the movement area. The innovation should make the machine more compact and can be kept smaller in dimensions both to the side and to the top. In addition, the easy changeability of the trajectory is sought for the purpose of adapting to bottle and box size, what so far with the well-known four-bar linkage with extended boom arm because of the unchangeable Motion curve was not possible.

The solution to this problem takes place according to the innovation in that as a vertical lifting device for the holding frame equipped with packing heads on or on a carrier carriage that is horizontally displaceable in a known manner, a coupling gear that can be driven separately from it is arranged, which has a lowerable arm under the carrier carriage, the end of which is straight and is articulated to the holding frame.

The inventive device can in a known manner, the horizontal component of the movement of the holding frame through the known horizontally displaceable carrier car are generated while the vertical movement by a linear guide coupling gear takes place, which is stored in the carrier trolley. Just the boom the linkage reaches under the carrier trolley. The entire range of motion of the plasma frame is thus of more Drive elements released. The end of this cantilever arm will

including the holding frame articulated with it, vertically and straight up and down below the carrier trolley. The entire Coupling mechanism including drive can be arranged in or on the carrier car, so that any downwardly protruding supports for the coupling gear itself is completely omitted = there are neither since = borrowed at the end of the carrier car track nor upwards over the carrier car Far protruding drive parts available. By assembling the carrier carriage and the in or on it and with it displaceable straight guide coupling gear a compact design with small external dimensions is achieved. According to the innovation, it is also proposed that as a vertical lifting device a separately drivable straight thrust crank gear is provided on or on the carrier carriage, which is under the Carrier trolley lowerable boom arm (extended coupling) is articulated to the holding frame.

According to the innovation is therefore as simple and at least approximately and piece-wise straight coupling gear a straight thrust crank gear intended. Only that part of the movement that has just been carried out can be used that is below the carrier carriage runs. That is mostly only a part of the whole generated by the straight throttle gears. Straight lines.

According to the innovation, it is further proposed that an isosceles straight thrust crank gear is provided for exact straight-line guidance, in which the extension arm that is straight on the upper side in the carrier car has twice the length of the crank and the articulation point of the crank on the extension arm divides it into two equal pieces.
Will au? the carrier trolley an identical straight lifting crank

I gearbox built according to the innovation, then the holding frame I is exactly straight and, as desired, also perpendicular to the carrier trolley

leads. Only the half of the generated guide line that extends downwards under the carrier carriage is used. Because of the internal relationships of the isosceles straight thrust crank with a straight guide through a pair of cardan circles and the cross-loop gear known as the elliptical compass the exact straight-line guidance can be carried out at least in part by a straight-line crank with the help of the isosceles straight thrust crank are replaced, the crank arm as a so-called elliptical link with the radius of a vertex circle of curvature of the corresponding Ellipse is formed.

According to the innovation, it is further proposed that with the first cantilever arm which can be lowered under the carrier car, the second corresponding arm Cantilever arm is coupled to a parallel crank mechanism and that its lower oscillating end is articulated with the holding frame connected is. As a result, a parallelogram and thus horizontal guidance for the holding frame is achieved in a simple manner.

According to the innovation it is further proposed that the upper ends the cantilever arms are articulated on a ride-on trolley that can be moved horizontally forwards and backwards on the carrier trolley and that the cranks of the linkage acting on the cantilever arms are articulated to the bearing parts firmly connected to the carrier carriage are. Since the upper part of the arm of the coupling gear must be guided horizontally at the height of the carrier carriage, the innovation suggests especially with regard to the parallel crank mechanism for the horizontal guidance of the holding frame

-D-

Ride-on car in front of the carrier car horizontally and straight ahead. and is provided such that it can be pushed back and on which the extension arms are mounted with their upper end so as to be displaceable in the carrier carriage. Although it is already known to subdivide the holding frame itself and a part of the holding frame like a carriage to the other part of the holding frame to be slidable. As a result, however, only the packing heads of the holding frame itself can be pulled apart in this way be that the bottles received in a bundle in two juxtaposed bottle crates with the appropriate Center-to-center spacing can be used. A lifting movement for the bottle holder frame cannot be achieved by this known device can be achieved.

According to the innovation, it is also proposed that as a drive for moving the ride-on car back and forth on the carrier car a mechanical drive is provided. A mechanical drive provided on the ride-on trolley can be used as a mechanical drive Motor drive as well as a chain drive are provided, the ride-on trolley being arranged on the carrier trolley via chains Drive motor is moved. A rack and pinion or screw drive can also be provided, with the front and rear Moving back the direction of rotation of the drive element, for example the pinion, the screw or the chain, is changed. By pushing the ride-on trolley away from the storage area of the crank arm, the Flasohenhaiterrahmen is raised and through the approach of the ride-on car to the bearing point of the crank is lowered.

According to the innovation, it is also proposed that the ride-on car is guided horizontally straight without its own drive and the course

with the coupling gear by a mechanical, pneumatic or hydraulic drive is provided so that it can swing back and forth. The crank itself can be used, for example, via a helical gear, which is fixedly arranged on the carrier trolley, can be pivoted back and forth. The then rises and falls Haiterrahmen and the horizontally guided ride-on car without its own drive moves away from the paddock on the carrier trolley or is brought back to it after switching. According to the innovation, it is further proposed that the carrier carriage independent of the movements of the ride-on carriage in a known manner Way can be pushed back and forth. For the drive of the carrier car, a lifting cylinder or motor train or can be used in a known manner also a rotating mechanical gear that moves the carrier car back and forth - similar to that of the ride-on car hen will.

According to the innovation, it is further proposed that both for the carrier car and for the ride-on car independently of one another adjustable limit switches or limit stops are provided for the respective displacement movements. By the adjustable limit switches can adjust the size of the horizontal and vertical components of the movement of the bottle holder frames be set, changed and adapted, with a certain through the reachable end position of the ride-on car The height of the bottle holder frame above the bottle table is achieved regardless of the horizontal that has just been reached Carrier position. By adjusting the limit switch, both the vertical and the horizontal maximum deflection of the bottle holder frame can be set,

while the curve shape by the temporal superposition of the two Car movements can be changed within wide limits. As far as pneumatic or hydraulic drives for the shifting devices the carrier and ride-on trolleys are used, can be used in place of or together with limit switches also limit stops, preferably with braking or damping of movement. The timing of the drives of the two cars is expediently controlled by a be-1 annte program control that controls the individual drive units Impulses for acceleration, braking, forward and reverse travel are given.

According to the innovation it is further proposed that two or more the carrier carriage including the lifting device are arranged next to one another or one behind the other in the direction of movement of the carrier carriage. As a result, modular, larger machines can be built by arranging corresponding carrier trolleys next to one another, including the ones according to the innovation Devices are built.

It can be provided according to the innovation that two bottle holder frames simultaneously or one after the other on mirror-inverted, hook-shaped or gamma-shaped conveyor tracks Are movably arranged over the Gefäßförderereinrio.itungen.

It is also part of the innovation that the drives for the carrier car and coupling gear in the carrier car receiving _? Upper machine days are arranged.

All drives for one or more plate holder frames according to of the innovation are arranged directly in the plane of the support frame or a little above it, which means that they are also mirror images working against each other or modular construction

In the drawing, the innovation is shown as an example and schematically.,

Figure 7 shows the mirror image movement of two bottle holder frames in a double machine with a common drive deck.

The isosceles straight thrust crank mechanism shown as an example in FIG has a crank 1 and a cantilever arm 2. The extension arm 2 is twice as large as the crank arm 1. If the crank arm is size a, then the cantilever arm is 2 a size of 2 · a. The upper end of the cantilever arm 2 is on a straight line 3 running through the pivot point 4 of the crank 1 guided. A role or a sliding block 3a and guide rails 3b cause this straight guidance of the upper end of the extension arm 2. Under these conditions, the lower end point 5 of the cantilever arm 2 always moves exactly perpendicular to the straight line back and forth; at the same time, the crank arm 1 swivel movements

in the sense of the figure 7 and the sliding block 3a forwards and backwards movements in the sense of the arrow 7a. The fla-saw holder bracket 6 linked at point 5 carries out a mathematically precise linear movement perpendicular to the straight line 3. If the straight line 3 runs horizontally, the bottle holder frame 6 carries out precise vertical up and down movements on the straight line 8 of the lift. For the lifting movement of the frame 6, only the part of the lifting line 8 lying below the straight line 3 is used.

As long as an approximate straight line is sufficient, the straight thrust crank according to FIG. 1 can also vary somewhat in its dimensions, for example the front part of the cantilever arm 2 can be longer than a. Likewise if the other dimensions of the crank mechanism vary somewhat or if the crank 1 is designed as an elliptical link and the articulation point 9 leads on the log circle of an ellipse belonging to the cardan circle, γόη point 5 piecewise approximated straight lines are described, which, however, are at the top and bottom deviate more and more and turn into loaves, loops or loops. On the other hand, with an isosceles straight thrust crank mechanism with the dimensions according to FIG. 1, trajectories 8 for point 5, which are mathematically precisely straight in the end pieces, are obtained. For use in accordance with the innovation, the coupling gear according to FIG. The crank arm 1 is rotatably arranged in the bearing 11, which in turn is firmly connected to the carriage 10. The extension arm 2 is articulated to a ride-on trolley 12 at the upper end.

de to and fro movement on or in the carrier carriage 10 is restricted. If, as shown in FIG. 2, the ride-on carriage 12 is in the position 12a, the lower end point 5 of the boom arm 2 is in its upper position 5a. However, if the ride-on carriage 12 is in position 12b (crank 1 ^!, Dashed), then the lower end point 5 of the extension arm 2 'is in the lower position 5 ) 15 moved in the direction of arrow 16 in the position 10b (crank 1 ", boom 2"), then the end point 5a of the boom 2 moves a piece to this side exactly corresponding to the displacement of the carriage 10 in the position 10b, whereby the on Point 5 hinged bottle holder frame 6 experiences a sideways movement. If the ride-on trolley is now approached from position 12a approximately to position 12b, then sisii the PuEotfc 3 "rfieacif cvwes äa tsid initially lowers into position 5c. In this way, for example, a hook-shaped movement curve 22 with the extreme positions 5 *> * 5a, 5c. If the movement of the outside carriage 12 takes place at least partially at the same time as the carrier carriage 10, an arbitrarily rounded, arcuate trajectory (dashed) can be generated instead of an almost right-angled trajectory curve 22. The size of the horizontal component of the trajectory 5a, 5c can be changed by moving the carrier trolley from position 10a to position 10b and back to different lengths. The differently large displacement of the ride-on trolley from position 12a to position 12b and back causes a different-sized vertical component of the part of the movement babn 5a, 5b. In this way, the lifting curve 22 can in -wide sizes zen and

the. It is therefore only necessary to shift the carrier carriage 10 and change the displacement of the ride-on vehicle 12 by arranging adjustable limit switches or stops su and the Overlay of the shifting movements of the car 12 and 10 set respectively. to vary.

Figure 3 shows the extension of the straight thrust crank mechanism a second cantilever arm 2a and the connection to a parallel crank mechanism. The lower ends 5 of the cantilever arms 2 and 2a are arranged on the holding frame 6 by a coupling 17 * is connected to each other.

In this way, the holding frame 6 is inevitably always guided horizontally on the trajectory 22 (FIG. 2).

As the Mgis = 5 shows, in addition to the crank i, a second crank la νχιύ a parallel coupling 17a connecting the two crank articulation points 9 and <? a can be provided.

upper ends of the cantilever arms 2 _S 2a, these ends with RoI- | len 13 are guided on straight line 3. The spread of the straight | Slider crank mechanism according to FIG. 4b is indicated by arrow 20. The bottle holder frame 6 lifted upwards according to FIG. 4b is then shifted to the side as far as above the bottle table 21 according to FIG. Typically, the FIasahenhalterahmen 6 is then lowered again slightly down and relieves the hanging on the bottle grippers bottles, so that the \ bottles are placed on the bottle table 21 downward NEN kön-%. During this movement (Figure "4a to 4c) of the bottles \ describes rule holding frame 6 that is, a hook-like web 22 (vergl.auch Fig.2) on which the bottle holding frame 6 then runs back into the starting position (4a). During the return movement, the bottle holder frame 6 can also describe a shortened shape that differs somewhat from the curve 22 because it then does not carry any bottles. This can be set in advance by a program control. Instead of a hook-like movement path 22 of the bottle holder frame, a portal-like movement can also be implemented. In the position of the bottle holder frame 6 indicated in FIG. 4c, only the bottle holder frame 6 then has to be brought back down to the starting height. Such a curve is particularly useful, for example, for the implementation of a packing and unpacking process according to patent 1,217,850 and realizes the web shape required there without complicated guide devices. Insofar as the device according to the invention is to be used as a packer, the bottles are accumulated on the bottle table 21 in accordance with FIG. 4c, removed from this bottle accumulation table, in accordance with FIG

Page over the box station 18 and into the boxes 19 used, similar to Figure 4a. However, the direction of movement when packing (Fig. 4c, 4a) is, as usual, the opposite of when unpacking (Fig.4a, 4c). The entire drive for moving the holding frame 6 is arranged in the drive tier 23 above the bottle table 21 and the crate station l8. The extension arms 2, 2a reach from top to bottom, whereby neither up nor to the side protruding gear devices are required, accordingly the machine has small external dimensions, works quickly and easily and is clearly structured. FIG. 5 shows a reciprocating piston device 24 as a displacement device for the carrier carriage 10 and the ride-on carriage 12. The cylinder is stored on the machine frame of the drive floor 23 and the end of the reciprocating piston is connected to a driver 24a of the carrier carriage 10. By introducing a print medium into the cylinder the carrier trolley 10 can optionally bezw. alternately after both Richtimgen are moved, he through the rails 15 straight is led. On the carrier carriage 10 is a separate, hydraulic or pneumatic displacement device 25 with a cylinder and arranged piston which engages the ride-on carriage 12 and moves it back and forth on the carrier carriage. In Figure 5 are adjustable stops and / or limit switches 27a and 27b for the carrier carriage 10 and adjustable stops or Limit switches 28a and 28b for the ride-on trolley 12 are provided. As far as stops are provided, they are the stroke of the sliding elements 24 and 25 and limit switches cause reversal or stroke limitation of the sliding elements. The control is therefore carried out in a known manner by known switching devices
