ABSTRACT
The invention relates to an apparatus for moving items, and in particular, for moving a stack of wrappers or envelopes to be packed from a delivery device to a packing station with a connecting-rod-less cylinder comprising compressed air supply ducts, seals, and guiding rollers in its cylinder heads and tension means which connect the piston to a carrier for a sliding member, characterized in that the piston, at the beginning of its operating stroke, bears on the pressure side against a pressure-chamber.
Description
~2~6~
The invention relates to an apparatus for moving items, and in particular, for moving a stack of envelopes to be packed from a delivery device to a packing station with the aid of a connecting-rod-less cylinder comprising compressed air supply ducts seals and guiding rollers in its cylinders heads, together with a tension means which connects the piston to a sliding member carrier.
An apparatus of this kind is known from German Vtility Model 86 32 668. In order to move the stack away from the delivery device, a piston is triggared in a connecting-rod-less cylinder by a pressure line connected thereto causing a sliding member to be moved very quickly. It has ~een ascertained that the time available to move the st~ck away from the delivery device is very short when individual envelopes are arriving extremely quickly from the delivery device. It is, therefore, a purpose o~ the invention to desicin an apparatus of the type in question in such a manner that, even with extremely shork cycle times, the delivery device is capable of sliding one end o~ the stack out of the working range of the delivery device.
; ~ According to the present invention, this object is accomplished in that the piston in the connecting-rod-less cylinder at the beginning of its operating stroke forms a pressure-chamber and is at a distance from its associated cylinder head.
At the beginning of the operating stroke, the pressure ~chambe~ located between the piston and the cylinder head is ~filled with an expansible pressure medium, for example, ~C/jj 1 :, ,': ..
~!326~
compressed air. Expansion of the pressure medium forces the piston to move extremely quickly at the beyinning of the operating stroke. The piston is held in its starting position by a braking device and can be moved by the pressure medium contained in the pressure chamber only when the braking device is releasPd. Thus, the velocity of the piston at the beginning of the operating stroke is not dependent upon the supply of compressed air but upon the magnitude of the volume of compressed air contained in the pressure chamber between the cylinder head and the piston. This substantially larger volume causes the piston to accelerate more quickly at the beginning of its operating stroke than the piston acceleration near the end of the stroke. ~he result is that the carrier is pulled along by the piston, and the sliding member which is secured thereto pushes the stack very rapidly out of the working range of the delivery device.
Further characteristics of the invention may be yathered from the specification and claims in conjunction with the drawing.
The invent~on is described hereinafter in greater detail in conjunction with the preferred embodiment illustrated in the drawing, wherein:
Fig. 1 is a side elevation of an apparatus for packing ; ~ envelopes:
Fig. 2 is a section through a connecting-rod-less cylinder;
Fig. 3 is a section through the connecting-rod-less cylinder showing a first sliding member; and ~. ...:
YC/jj 2 ~..
~32~
Fig. 4 is a section through the connecting-rod-less cylinder showing an alternate sliding member.
An apparatus 1 for packing envelopes 2 in cartons 3, cardboard boxes or the like comprises a machine frame 4, a delivery device 5 for individually arriving envelopes 2, a stack section 6, a station 7 for filling the envelopes 2 into cartons 3, and means for driving the moving parts.
Delivery device 5 places envelopes 2, as they arrive at one end of stack section 6, upon a table 8. In this area, stack section 6 may comprise brushes, not shown in Fig. 1, -which are arranged in parallel with each other and at the side of a slot 11 located in table 8. The two brushes hold the envelopes after they have been delivered and prevent them from falling over. The envelopes move automatically between the brushes, away from delivery device 5, as they are delivered.
The two brushes are o~ limited length in the longitudinal direction of the stack. As soon as stack 12 is longer than the brushes, a freely sliding stack support 13, urged by a constant force towards delivery device 5, holds the envelopes emerging ~rom between the brushes. This stack support 13 is arranged upon a carriage 14 which is adapted to move along the underside of table 8 in the longitudinal directisn of slot 11, with the stack support 13 extending through the slot 11.
: ~ ~ .:, A constant force is applied to stack support 13 by a freely suspended weight 15. It engages with carriage 14 by means of a cable 17 guided over a roller 16. Apparatus 1 also comprises a sliding member 18 which is adapted to move upon ~
. '-YC/j~ 3 -- ~ 3 ~
table 8 and which approaches stack 12 as soon as the stack 12 reaches a predetermined size. When a definite number of envelopes 2 has passed from delivery device 5 to table 8, sliding member 18 moves stack 12 against the resistanc~ offered by stack support 13 and weight 15 to filling and boxing station 7 (Fig. 1).
Sliding part 18 is caused to move by a piston-cylinder device 19 located on the underside of table 8. The cylinder of device 19 is a connecting-rod-less cylinder or a slotted packing cylinder 20.
Controlled throttle valves 21 are arranged in compressed air line 22 running to slotted cylinder 20 and are triggered in such a manner that sliding member 18 and the end of stack 12 leaves the delivery area within the cycle time of delivery device 5, i.e. very rapidly. The sliding member 18 moves stack 12 to filling and boxing station 7 which it reaches at a lesser, i.e. normal, speed. A stationary stack-support 23 and, for example, a retaining part 24, mounted pivotably upon table 8 and capable o~ being lowered and adjusted, accept the compressed stack between them in such a manner that a carton or box 3 can be pushed onto stack 12 in a manner which is of no consequence here. On the return stroke, mobile stack support 13 and sliding member 18 descend under table 8 and return to their starting positions in the vicinity of stack section 6.
More specifically, stack support 13 travels back under ; filling and boxing station 7, while sliding member 18 moves under the new stack 12 now being formed to the holding position , ,:,.

shown in Fig. 1, i.e. in front of stack 12. When stack support13 and sliding member 18 are located in the vicinity of stack section 6 in front of delivery device 5, they ascend again upwardly through slot 11 in table 8.
In order to move front stack support 13 and sliding member 18 out of th2 path of travel of stack 12, i.e. to lower and to raise them, the whole piston-cylinder device 19 is lowered and raised accordingly by means of a hoist 25 which may be in the form of an additional piston-cylinder device, for example. -Piston-cylinder device 19 (Fig. 2), serving to displace sliding member 18, comprises the above-mentioned cylinder 20 having a cylinder bore 26~ a rod~less piston 27 and two cylinder heads 28, 29 with guiding rollers 30. Extending in parallel with cylinder bore 26 is a cross-sectionally C- -shaped guide 31 fvr a carrier 32 which is connected to piston 27 by a tension means or strips 33, 34 passing over guiding rollers 30. Located in the cylinder heads 28, 29 are compressed air supply ducts 35 and passages 36 with seals 37 for strips 33, 34.
The one strip 33 extends from carrier 32 running in :
guide 31, over left hand guide roller 30 (Fig. 2), to piston 27. The other strip 34 extends from carrier 32, over right hand guide roller 30, to piston 27. Both strips 33, 34 pass, hefore and after rollers 30, through passages 36, 37 before entering cylinder bore 26. The interior of cylinder bore 26 ; is connected, through suitable lines, to throttle valves 21, , a control valve 38 or a control device 38 (Fig. 1), through ;--.
YC/jj 5 ~l 3 2 ~
compressed air supply ducts 35, and to a compress~d air source not shown in the figures.
Strips 33, 34, arranged between piston 27 and carrier 32, are of different lengths. Thus in the embodiment shown in Fig. 2, strip 33 is longer than strip 34. This ensures that at the beginning of its operating stroke piston 27, forming a pressure chamber 39, is at a distance from the associated cylinder head 28 in connecting-rod~less cylinder 20. This pressure chamber is a part of cylinder bore 26 and possesses a correspondingly large cross-section and a large volume in comparison with the cross-section and volume o~ compressed air supply duct 35 in associated cylinder head 28. At the beginning of the operating stroke, a very large compressed air mass acts upon piston 27 which results in the piston 27 moving very rapidly from its position of rest in low pressure cylinder chamber half 40. The movement of carrier 32, connected by strips 33, 3~ to piston 27 and carrying sliding member 18, as shown in Figs. 3 and 4, is correspondingly rapid at the beginning of the operating stroke.
In Fig. 2, carrier 32 is shown only in principle.
Details thereof may be gathered from Figs. 3 and 4.
In order to ensure that at the beginning of its operating stxoke piston 27 remains in the position shown in Fig. 2 (with a higher pressure contained on the one side in pressure chamber 39 and a lower pressure contained on the other . . .
side ln pressurP chamber 40), carrier 32 comprises a controlled braking device 41. This operates preferably with compressed air and is provided, through a connector 42 (Fig. 2) on carrier YC/jj 6 ,.:

32 and through lines not shown, with compressed air or hrake-air.
According to Fig. 3, carrier 32 comprises a member 43 which projects from U-shaped guide 31 and serves as a carrier for sliding member 1~, and components located in the interior of guide 31. These components include a centrepiece 44 and lateral parts 45 arranged symmetrically and in mirror image therewith and comprising externally a plurality of radial passages 46. Member 43, centrepiece 44 and lateral parts 45 are connected to each other through elements not shown.
Passages 46 lead to at least one centrally arranged channel which is secured ko connector 42 (Fig. 2) in a manner not shown.
Located between lateral parts 45 and contour 48 of guide 31 are cross-sectionally U-shaped sliding and braking elements 49. As soon as pressure is huilt up in a channel 47 -~-and passages 46 in lateral parts 45, sliding and braking elements 49 are locked to contour 48 o~ guide 31, thus locking carrier 32 and piston 27 simultaneously. However, if the brake pressure is abruptly lowered, piston Z7 is free to begin an operating stroke and to move carrier 32.
As also shown in Fig. 3, cylinder 20 comprises lateral walls 50, 51 carrying longitudinal guide grooves 52 in which ~-arms 53 of carrier 32 are guided with rollers 54.
For the purpose of controlling braking device 41, use -is made, among other things, of sensors 55, 56 arranged on carrier 32, sliding member 18 (Fig. 3) and machine frame 4.

Accordiny to Fig. 3, sliding member 18 comprises two parting fingers 57, which pass through slot ll in table 8. An alternate sliding part 18a according to FigO 4 comprises four parting fingers 57 arranged side-by-side, the two outer fingers being adjustable and lockable in a guid~ 58 in relation to inner parting fingers 57.
Because of the greater width of alternate sliding parts 18a, support pieces 59 are arranged at the side of cylinder 20 and serve as carriers for brackets 60 and linear guides 61. Also pertaining to sliding parts 18a is an angle member 62 with guide bushings 63 which slide upon linear guides 61. Finally, anglè member 62 is connected appropriately to member 43 of carrier 32, as shown in detail in Fig. 4.
According to the example ilIustrated in the figures, cylinder 20 is longer than the operating stroke. However, the invention is not restricted to a design of this kind, and amendments and modifications are possible within the scope of the invention. For instance, pressure chamber 39, defined by the terminal position of piston 27 in cylinder 20, may be replaced by a separate pressure chamber for piston 27 which is independent of cylinder 20.
