Definitions

  • the invention relates to a device for adjusting the receiving volume of a workpiece carrier held on an intermittently moving strand, which has at least one outer side wall which is essentially flat, which is closest to the strand and extends parallel to this and to the conveying direction of the workpiece carriers.
  • a wide variety of conveying devices are known for the transport of workpieces, with the focus here being on conveyors in which the workpiece is received and conveyed in a carrier held on the conveying strand.
  • conveying devices preference is given to liquid packs which are transported directly on conveyor belts even without a carrier, and whose processing, in particular filling and closing, is preferred in a workpiece carrier; for positioning purposes alone.
  • This object is achieved in that on the inner surface of the workpiece carrier in the direction of its longitudinal center axis at a distance from each other recesses for inserting a stop part at different heights with the aid of the stop part engaging adjusting device for positioning the workpiece that the workpiece holder is in the form of both Has open ends sleeve and that the stop member carries the bottom of the workpiece and is movable relative to the workpiece carrier in the vertically offset recesses such that it can be inserted or pulled out from one side in the direction of the longitudinal central axis of the workpiece carrier at a certain height can.
  • recesses are arranged at various points, with which one or more stop parts can come into engagement.
  • Such a stop part can for example be a base plate, a pin or the like be, the function of the stop is important, namely that the workpiece in the workpiece carrier approaches a certain stop. It goes without saying that when the workpiece is moved deeper into the carrier, larger workpieces or those with a larger volume can be picked up and transported; and vice versa, when moving in by only a shorter piece into the workpiece holder, only workpieces with a smaller volume can be carried, picked up, conveyed and possibly processed.
  • the recesses can be grooves, slots, holes of various shapes, etc.
  • Another advantage is the shape of the workpiece carrier, namely a sleeve that is open at both ends. Because the present invention is particularly useful in transporting and holding plastic paper or cardboard fluid packs, the advantages of the various embodiments are described in connection with such packs. Any sleeve-shaped workpieces and in particular such packs have a sleeve shape at a certain stage of manufacture. The similar geometry of the workpiece and its carrier clearly results in the workpiece being held well in the carrier. Especially in the above-described in-house testing of workpiece carriers, it has been shown that the good accessibility of recesses from the outside, for example that base plates in grooves can be pushed into the workpiece carrier from the outside, requires the creation of large free areas on the side walls of the workpiece carrier.
  • the stop part is a base plate, the edges of which can be brought into engagement with the recesses on the workpiece carrier.
  • the base plate is inserted from the outside via a slot arranged at a certain height with respect to the longitudinal central axis of the workpiece carrier and can be readjusted to a different position from this special position by pulling it out, moving it in the direction of the longitudinal central axis of the carrier and reinserting it at another location with similar recesses. As a result, the receiving volume of the workpiece carrier is adjusted.
  • the sleeve-shaped workpiece carrier is mentally set up vertically so that its longitudinal central axis runs vertically.
  • the different heights for different holding volumes of the workpiece carrier thus mean the arrangement of a stop part, e.g. a base plate, vertically above, vertically in the middle or after vertical adjustment downwards in the lower area of the workpiece carrier.
  • the workpiece preferably the package to be machined
  • the workpiece carrier is inserted from above through the free end of the workpiece carrier and pressed vertically downward until the bottom of the package, which is preferably open on one side at the top, touches the stop part, preferably the base plate , strikes and is supported there.
  • the movement of the stop part into or out of the interior of the workpiece carrier is also important for the invention, and the person skilled in the art can when using a base plate as a stop part, easily imagine that the base plate is inserted in the horizontal direction, which in the sense of the invention means nothing other than perpendicular to the longitudinal central axis of the workpiece carrier; and, incidentally, also perpendicular to the conveying direction of the strand on which the conveyor the member with which the workpiece carrier is connected.
  • An embodiment with a direction of movement of the stop parts in the horizontal direction is particularly expediently designed according to the invention in that the stop part can be moved with at least one movement component perpendicular to the conveying direction of the workpiece carrier and perpendicular to its longitudinal central axis relative to the workpiece carrier, partially penetrating it.
  • a preferred embodiment is characterized in that the recesses are designed as parallel, straight grooves opposite one another in pairs, in which the base plate can be loosely displaced by an adjusting device arranged at a distance next to the strand with the workpiece carriers.
  • the base plate is selected as the embodiment of the stop part.
  • the setting device can have a simple structure, as shown by some exemplary embodiments described below.
  • the adjusting device has a lifting part for moving a gripping system which can be connected to the base plate in a direction parallel to the longitudinal central axis of the workpiece carrier and a sliding part which can preferably be moved by the lifting part for moving the gripping system transversely to the longitudinal central axis of the workpiece carrier and transversely to its conveying direction.
  • the movement of the stop part is divided into the vertical movement defined above on the one hand and the horizontal movement on the other hand.
  • the lifting part ensures vertical movement and the sliding part ensures horizontal movement.
  • the sliding part is carried by the lifting part and moved up and down in the desired position parallel to the longitudinal central axis of the workpiece carrier. If this position is reached, the sliding part is actuated and moves the gripping system towards the stop part still in the workpiece carrier, pulls it out, is moved again by the lifting part to move and, after stopping the movement of the lifting part, pushes it horizontally back into another position Workpiece carrier into it, so that the receiving volume of the carrier is adjusted as quickly as possible.
  • the stop part is designed as a switching pin that can be inserted into the interior of the workpiece carrier and can be pulled out of the interior of the workpiece carrier, that at least two switching pins are provided and by two corresponding ones as the workpiece carrier wall Completely penetrating holes are displaceable by means of control bodies.
  • No bottom plate is used in this embodiment.
  • Many workpieces can be inserted into a carrier with a certain amount of friction so that they stop more or less at the desired position after the pushing force has ended.
  • the pack should move against a stop part, in the present case, for example, against a switching pin. The volume the workpiece carrier is then precisely adjusted.
  • the recesses on the inner surface of the workpiece carrier are holes in this embodiment, which completely penetrate the respective workpiece carrier wall. It is expedient to provide at least two holes spaced apart from one another and thus also switching bolts, so that stops for the inserted pack are provided at two different locations or at different heights in the workpiece carrier.
  • a third position can be automatically achieved, for example, in that the lower end of the workpiece carrier has at least partially a fixed stop in the form of an edge or a bottom. At this end, the sleeve can still be open, but there is a fixed stop for all those cases where the workpiece carrier is to be set to the largest volume, i.e. where the pack is pushed from above through the entire carrier down to the end stop shall be. In this case, both switching pins are then withdrawn from the holes in the workpiece carrier walls or the side walls of the workpiece carrier in such a way that no faults occur when the workpieces or packs are pushed in and sliding past.
  • Control bodies are provided in order to switch the switching bolts in the simplest possible way.
  • two separate control bodies can be moved back and forth independently of one another by a lifting part in the direction parallel to the longitudinal central axis of the workpiece carrier and each carry a control cam in which outer stops of the switching bolts are slidably guided.
  • the outer stop can be, for example, a head of one piece with the switching pin, as with a screw head, but an L-shape would also suffice in the longitudinal section of the switching pin.
  • the only thing that matters is that the side flank of a control cam interacts with a part of the switching bolt which extends in the so-called vertical direction in order to actuate it.
  • Two separate control bodies are arranged vertically one above the other, the control cams facing each other for better protection, but can be moved separately in the vertical direction with a corresponding lifting part. This movement makes it possible to provide for an engagement of the control cam with the switching pin or to avoid such.
  • the control of the switching pins is practically carried out by the conveying movement of the strand and thus the movement of the workpiece carrier itself. This is namely because the strand is moved in the second horizontal direction described, which is perpendicular to the horizontal sliding movement of the stop part.
  • the control curves also have an extension component in this second horizontal direction, but also a component in the first horizontal direction for pulling out or pushing in the switching pin from or into the workpiece carrier. If the workpiece carriers move with the strand in the second horizontal direction, then the switching pin is pulled out or pushed into the workpiece carrier via the respective control cam when it is brought into engagement with the switching pin.
  • the control of the lifting part decides whether both or only one switching pin is moved.
  • the change in the volume of the workpiece carrier is therefore advantageously carried out automatically by the further transport of the strand with the workpiece carriers.
  • the cross section of the workpiece carrier can have different shapes, as has already been indicated variously.
  • it is preferred for special types of packaging if the cross section of the workpiece carrier is circular.
  • This embodiment can be used in particular if the switching bolts described above are used, because a round packing of switching bolts in a sleeve-shaped workpiece carrier with a circular cross section can also be set precisely.
  • the cross section of the workpiece carrier is formed from at least two opposite straight sections and rounded corners connecting the latter from two semicircular or four quarter-circular round sections. Packings which are essentially square in cross section but whose corners are rounded can be accommodated particularly well in such workpiece carriers. Then two pairs of opposite straight sections connect four quarter-circular round sections. If all these sections are placed next to one another, the cross-section of the workpiece carrier has the same shape as the outer shape of the package to be accommodated, which is why it is firmly seated in the workpiece carrier and can be precisely adjusted to the correct volume by the stop parts. It is easily conceivable that irrespective of the cross-sectional shape of the workpiece carrier, a side wall of the workpiece carrier can be flattened on the inside in order to connect the workpiece carrier to the link of the conveyor line via this flat outer surface.
  • an elongated hole running parallel to the longitudinal center axis is formed in two opposite side walls of the workpiece carrier. This is an opening penetrating the outer wall of the workpiece carrier, through which pins located on the base plate can protrude from the interior of the workpiece carrier to the outside thereof, so that a gripping system provided with forks via the pins protruding outward is nevertheless located in the interior of the workpiece carrier Bottom plate can engage.
  • This gripping system with fork and pins attached to the base plate has already been indicated above. Specific embodiments are described below.
  • a workpiece carrier 3 is attached to the link, generally designated 1, of a strand consisting of several links and moving in the conveying direction 2 (according to the illustration in FIG. 1, for example on both sides). It has a square cross-section with rounded corners. Here you can see four straight sections 3a, which are connected by four quarter-circular, round sections 3b.
  • a flat side wall 4 is arranged on the outside, which is identical to one of the four straight sections 3a, but is pulled somewhat outward from the composite of the entire cross section in order to provide a better possibility of fastening the workpiece carrier 3 to the link 1 of the strand.
  • FIG. 1 and 2 also show the recesses made on the inner surface of the workpiece carrier, which are generally designated by 5 and are formed here in this first embodiment as parallel, straight grooves 5a lying opposite one another, also in alignment with these grooves 5a slots 5b which completely cross the outer wall must be provided. In the illustration in FIG. 2, these lie in the area of the left two partial sections 3b drawn in broken lines and the straight section 3a of the workpiece carrier 3.
  • the longitudinal central axis of the workpiece carrier 3 is designated 6 and is perpendicular to the conveying direction 2 of the strand and thus also the workpiece carrier 3, but is also perpendicular to the so-called horizontal direction of movement 7, which is illustrated in FIG. 1 by the straight double arrow below.
  • the recesses 5a, 5b must be arranged at a distance from one another at different heights in the direction of the longitudinal center axis 6 in order to specify the desired adjustment positions.
  • the upper side of the sleeve of the workpiece carrier 3, which is formed from continuous casting, is at the bottom in FIG.
  • a base plate 9 is used as a stop part, which is a Cross-section L-shaped gripping edge 9a has to give a starting point for gripping claws 10a so that the horizontal movement in the direction of the double arrow 7 for the base plate 9 is made possible.
  • the edge 9b of the base plate 9 comes into engagement with the recesses 5 on the workpiece carrier 3, in particular as shown in FIG. 2, in that the base plate 9 is pushed horizontally into or into these grooves 5a. It is not necessary for the base plate 9 to completely disappear in the interior of the workpiece carrier 3 in such a way that it does not protrude outwards through the openings 5b.
  • the stop function for those who fail The pack to be prevented is fully achieved even if it is partially pushed in and stopped.
  • the base plate 9 is pulled horizontally, for example, from position II to the left in the direction of arrow 7 so that it is completely free of the workpiece carrier 3. Then it must be in the vertical direction according to double arrow 8 e.g. moved up or down to position III or I and there again horizontally pushed in the direction of arrow 7 into the next recess 5.
  • the adjusting device 10 has a lifting part (not shown in FIGS. 1 and 2) and a sliding part 11 with a holding body 12 and two guide rods 13 arranged vertically one above the other and guide strips 14 on the outside, in which there are notches 15. At the front end there is an end plate 16 on which the gripping hook 10a is attached.
  • the operation is now as follows:
  • the strand member 1 moves continuously according to FIG. 2 in the conveying direction 2 from bottom to top and according to FIG. 1 accordingly in the direction of view of the paper plane.
  • the workpiece carrier 3 moves with the inserted base plate 9 with its gripping edge 9a into the gripping hook 10a and remains at a certain time due to the intermittent operation of the strand.

  • the holding body 12 can remain in this position III, and the transport with the strand members 1 can continue in its direction 2.
  • This implementation is very time-saving, so that the standstill of the strand links 1 requires very little time. This short time can dictate the cycle time of a packaging machine.

If the lower switching pin 9b shown in FIG. 5 is extended (as not shown in FIG. 5), the pack can only be moved into the workpiece carrier 3 by the shortest length, namely to position I. It does not matter which position the upper one has of the two switching pins 9b shown in FIG. 5, on the other hand, if the lower switching pin 9b is retracted, but the upper switching pin is provided so as to protrude into the interior of the workpiece carrier 3, then the package can reach position II.
