The new transport device generally comprises a continuously "movable (approximately advancable) main track, which in principle consists of a belt 1 (or belt) which is formed from a relatively stiff material with a low coefficient of friction, for example from acetal plastic, and in an in Mg ₀ 3 and 4, which clearly defines the length of the path of the transport device The belt 1 fitted from the sides has stops 3 which have a bevel 4 at their front end. The belt points along its entire length perforations 5 for cooperation with a preferably semi-circular feed teeth of two transport or _o sprockets 6 and 7 for driving the belt about the belt to move at a low expenditure of energy to achieve the desired strikes, the -. as can be seen from Fig. 1 - can have relatively sharp curvatures, the drive is carried out according to the! inflation so that the belt is both a push and is also subjected to a pulling action by means of the toothed drums 6, 7, which for this purpose each act via their part of the belt and are driven, for example, by means of belts 8 and 9 from a pulley 10 which is keyed on the drive shaft of a vertically arranged machine. The drive shaft 11 can drive these two tracks (or lines) in the version with two tracks inserted one above the other - as shown

For this purpose, a support 129 is attached to the tube 37 by means of a yoke 128 "and with this one Guide plate 130 pivotally connected to an inclined edge 131. The guide plate 130 is typically used in the position shown in Pig * 21 by means of a not illustrated spring} this weak spring allows the plate 130 over the passage up to a wearer swing. However, if the wearer reaches his position after. 20, the plate swings back under the rod 50 of the wearer and thereby holds the wearer firmly against the Swinging movements. To prevent the carrier from being lifted from the tube by inserting the object into it a spring-loaded yoke 132 is used, which acts on the flange 62 of the carrier approximately via the rod.

The carriers pass the scanning apparatus so that they are exposed to the action of actuating members 65 which are under the influence of parts 155 of the scanning plates. The actuating members 65 operated by the actuating elements of the addressing apparatus then act on the correspondingly attached plates 135 and 136. If these plates - as can be seen from FIG. 26 - are of different types, the pin 140 can only be adjusted to the left in this figure if both the plate 135 and the plate 156 have been actuated, with a number or _{0 for this purpose} Elective level code is suitable. Those carriers that have a code that does not correspond to the code set in the scanning station naturally pass through the scanning station without influencing (or disturbing) the same, i.e. different from scanning in which the arms 142 are pivoted counterclockwise , whereupon they return to their original position by gravity. If, on the other hand, a carrier has the same code as the scanning device, the actuating elements first bring about an opening between the scanning splices, whereby the pin 140 is pivoted into its position shown in dashed lines in FIG. This pivoting movement can be brought about by the dead weight of the structure (or set) 139-142 or by a weak spring. During the pivoting movement, the arm 141 runs along the inclined

by actuating one of the actuating elements of the in in this case is the only carrier bearing the number 0. The respective actuating element "is located on the hone the tongue 169 'so that it will actuate said tongue when the wearer arrives at the holding device. In the initial position shown "are the holding levers 163rd in a position in which they allow the carriers ^ -sn, the Holding device to pass. However, if the holding device is reached by a carrier carrying the code Hull, so "his zero-actuator actuates the tongue 169, which moves the holding plate 168 counter-clockwise, so that the rod 166 is from the top edge of the plate 168 is resolved.

Group traverse the device, so that this at the same time came into their provision for the implementation of a new operating process

As already stated in connection with 5 ¹ Xg, 17, the downward forward. The carrier is only pushed by the loading arm 38 if no carrier is spatially in front of the feed claw, after which the downward advance takes place. For this purpose, the charger 103 is set up in such a way that it detects, in particular scans, the presence of a carrier spatially in front of the feed claw by means of a device illustrated in FIG.

The charger contains a cover 174 of essentially the same type as that of the scanning device 135. A shaft 175 is mounted in this cover, around which a sleeve 178 is rotatable, on the periphery of which a retaining stop 177 is provided A holding stop is assigned a hook-shaped part 178 of a plate 179, which is articulated at 180 to another plate 181 attached to the cover 174. The plate 179 serves as the armature of an electromagnet 183. On the sleeve 176, a bell crank 183 and an obliquely extending tongue 184 is also mounted, is mounted so that according to the drawing, Figure 28, that t ^ e namely from the hub portion of a support however, it cannot be influenced by the flanges of the same. At its lower end, the sleeve 176 has a partial ring groove 185 which extends around

extends more than 180 °. The sleeve is under the influence of a torsion spring 186 which tends to rotate the sleeve clockwise. Another sleeve 187 is also provided on the shaft 175 and is intended to be rotated. Said sleeve has an axially extending portion 187a which is received by the cap 185 of the sleeve 178, allowing limited mutual movement between the sleeves, _etc. A downwardly directed rod 188 is attached to the sleeve 187, to which an L-shaped part 189 is attached, so that two parallel downwardly directed legs 188 and 189 are formed. These legs are arranged to extend inside the effective surface of the flanges of the beams. Both the tongue 184 and the legs 188, 189 protrude from an opening 195 in the cover 175. In addition, an arm 190 is attached to the sleeve 87, the part of which is not illustrated and corresponds to the lock 150 according to FIG. The actuation plate belonging to the charger is, however, denoted by in accordance with the illustration in FIG. A lock 192 that is used is attached to its front end by means of a lock attached to the cover 174.

"brought thread-like or" tape-like device 193 out; As can be seen from FIG. 29, the barrier has an inclined surface 194.

The charger works as follows: One arriving on track 37 and through holding means 107 a stopped carrier gives a microswitch, only shown in Fig. 17, an impulse, which in turn alone energizes the electromagnet 182, whereby its armature 179 falls off, which until then the sleeve 176 in its inoperative Position of Fig. 28 has retained and at which the

j legs 188 and 189 caused by means of continuous carriers

are to perform an oscillating movement only during the passage time of the carrier. The sleeve 176 and the with their connected links 183, 184 are pivoted down into the readiness position shown in FIG a carrier can be scanned.

If there is no carrier behind the first one on the charger = If the feed pawl is present, the tongue 184 is moved in the counterclockwise direction by the feed pawl The arm 183, which when excited (or acti-f four) of the magnet slides down below the lock, comes into contact with the same, so that the lock to the left is moved. The components shown in Figure 24 cause the actuator plate 104 of the charger to move back, whereby, in turn, the loading arm 38 (see Fig. 18)

'"30 **** * *" ** ** * · falls and the downward thrust of the carrier - as was explained in connection with FIG. 17 - can take place.

However, if there is a carrier in front of the feed claw which arrived at the loading device first, then guide legs 188 and 189 are the first to pivot in the counterclockwise direction. The arm 190 thereby abuts the inclined edge 194 of the lock notch, whereby the lock is brought into a position in which the arm 183 at the contact with the * lock notch ge * * is prevented because this arm has moved in the counterclockwise direction because the hub of the wearer is the tongue bumps; in this way the wearer is not exposed to the action of the arm 183. In this case, the actuator plate not withdrawn and as a result there is no encumbrance.

The innovation can be modified in some respects without relying on the principle on which it is based go off ,, For example - as was noted at the beginning - it can be advantageous to provide two main lines, the in particular are arranged one above the other. The upper main track can contain reserve carriers that run down at the points; can be brought here as they are needed, for what For example, an excess of carriers can be applied to the upper web by means of pulses. This train can also be used for transportation of so-called urgent products are used · But also in particular analogous deviations from the wording of claims are quite possible «,
