The invention relates to a device for stacking with horizontal conveyor belts fed forms, which are taken over by a set of vertical conveyor belts, from which one from the height of the feed level to the top of the full joint to be formed and a second shorter band extends to the intermediate level storing the stack.

The invention is based on the technical problem of designing such a device in such a way that that even slack forms can be reliably conveyed and stacked. This was with the previous ones Devices not possible. According to the knowledge according to the invention is namely a limp Always keep the form and take it with you. It must not leave a moment to itself will.

This is achieved according to the invention in that in the above-mentioned conveying device bendable forms an additional one lying on the same side of the shorter conveyor belt and with support rollers mounted on a slider, clamping band is arranged vertically in Guides can be moved up to the highest stacking level, and that on the slide by means of a rigid Frame a horizontal conveyor belt lying above the stack is attached, which the delivered Forms deposits on top of the pile and at the same time gradually lifted by the growing pile will.

This device according to the invention for stacking forms is particularly advantageous in sorting devices applicable.

How this is intended in detail will now be explained in more detail with reference to the drawings using an exemplary embodiment:

F i g. 1 shows a stacking device for flexible materials Forms;

Fig. 2 shows a sorting device for flexible ones Forms or mixing device in which a stacking device according to FIG. 1 is used will.

The stacking device according to FIG. 1 receives piece by piece pliable forms (Sf) from a source 24 (not shown) between a horizontal upper belt 3 running over rollers on axes 8 and 10 and a single printing belt 2, which is in its horizontal part with belt 3 and after an upward curve around rollers on axes 8 and 12, in its vertical part extending to the counter roller on axis 13 , cooperates with two vertical pressure belts 4 and 5, from device for stacking with horizontal ones

which the former has a roller on axis 8 and a Roll on axis 9 runs.

The axes 8 and 9 are fixed in the frame.

The other vertical printing belt 5 runs over rollers on axles 6 and 7, which are mounted at a fixed distance from each other in a slide in guides 25 and running. This slide forms a whole with the horizontal arm 14, which carries a horizontal belt 16, as well as an inclined counter-plate 15 for inserting forms that have been imposed from the conveyor belts.

The arm 14 rises a little with each excluded form (the highest position

of parts 14 to 18 is indicated with 74 to 78), since each form is deposited on the pile formed on the stacking plate 28. On the output side of the plate 28 there is an inhibiting roller 21. This stands still normally, as do the rollers 29 and 30 over which the output belt 27, which is used to output the shock, runs. The roller 21 is located at the bottom of the fixed vertical end plate 22 which forms the boundary. The forms can only be output when the belt 27 is driven (see below).

The axes 6 and 7 are located in Fig. 1 in their low-

most position. If this joint is completely filled, the axes 6 and 7 take the positions 61 and 71. You then also lifted the hatched band 5 upwards. The conveyor device described works between a fixed feeder beep _: 24 and the variable surface of a pile from which forms can be delivered again at the fixed level 23.

The sorting device (FIG. 2) consists of ten conveying devices according to FIG ) with a photocell F.

In these devices, zO to III represent insertion devices. A 0 to A 10 are removal devices, OO to O12 are stacking locations and SO to SLO changeover contacts, which go down when the stacking locations are empty. Wl to WIl represent switches. The sorting process proceeds as follows: A pile of forms to be sorted in sequence is placed in device 11 at stacking location Oll, causing contact 510 to rise. The + voltage activates the consumer ^ 410 via contact SlO. The issued forms pass the reading device F, which reads the unit number and passes it on to one of the switches W1 to W10 .

The drawing shows the moment in which the stacking place Oll is empty, whereby the contact SlO goes down and thereby unit 12 reports this emptiness.

This switches the photocell to the tens position, and at the same time a + voltage is switched to the tongue of contact SO, whereby the pick-up device is switched on (assuming that device O has been assigned some forms). As soon as stacking set OO is empty, contact SO goes down and worries about the decrease of stacking location Ol etc. via contact S1 Knowledge sets. This now instructs the photocell F to look at the hundreds and at the same time sets all contacts SO to S 9, if the relevant stacking locations have received forms, upwards, and now stacking location OO is emptied again, etc. As soon as the photocell F moves to the last one Digit is switched, contact S 9 not only switches the output device on normally when the contact is made downwards, but also sets the switch WU in the working position, whereby all forms are delivered to the stacking location 012. Here they arrive in sequence.

Forms which the photocell F cannot read accurately are transferred to the error magazine by the device 12 ΟΙΟ led.

It is clear that as soon as this space is empty after the forms have been placed in the stacking location Oll and the allocation process has begun, a new batch of forms to be sorted can already be placed in the stacking location Oll. As soon as the first pile has been deposited in stack set 0 12 (ie after the last drop of contact S 9), sorting (without interruption) of the second group of forms can begin.

Claims (2)

Patent claims: 1. Device for stacking forms fed by horizontal conveyor belts, which are taken over by a set of vertical conveyor belts, one of which is from the Height of the feeding level to the top of the full joint to be formed and a second, shorter one Belt extends to the intermediate level storing the stack, characterized in that that for the promotion of flexible forms an additional, on the same side of the shorter conveyor belt and mounted on a pusher with support rollers (6 and 7), clamping band (5) is arranged, which is vertically displaceable in guides (25, 26) up to the highest stacking level, and that on the slide by means of a rigid frame (14) a horizontal conveyor belt (16) lying above the stack is attached, which stores the delivered forms on top of the stack and at the same time through the growing pile is gradually raised. 2. Apparatus according to claim 1, characterized in that this stacking device in Sorting devices is applicable. Considered publications:
