Description

Warenzwischenlaaervorrichtuna

The present invention relates to a goods intermediate storage device with a transfer device for transferring goods to a manipulator.

For the storage of goods, such as medicines in pharmacies, various types of bearings are known. In so-called automatic warehouses, manipulators fill storage areas, such as canal warehouses with storage channels. For removal, the manipulator removes the corresponding goods from the storage area.

For some types of goods, which are only rarely used, so-called slow-moving devices, or even for goods that are used very frequently and are therefore often present in large numbers, so-called fast-moving parts, it is sometimes necessary to temporarily store the goods for a longer period of time, before they are supplied to the further flow of goods.

From DE 20 2015 006 649 Ul it is known that goods are stored in roll containers or box-shaped containers with several compartments. These serve as a loading device for an automatic warehouse. In the roll containers or box-shaped containers, the goods are received disorderly in subjects. A disadvantage of such intermediate storage devices is that the goods are stored on the one hand disorderly and beyond a single removal of goods is not possible.

It is therefore an object of the present invention to provide a goods intermediate storage device, which can allow an orderly storage of goods and moreover advantageously a removal of goods, especially of individual goods. The invention is defined by the features of claim 1.

The goods intermediate storage device according to the invention has a plurality of storage channels in which goods can be stacked on top of each other. The goods intermediate storage device further comprises a manipulator for dispensing the goods and a transfer device for transferring goods to the manipulator. The bearing channels each have a side wall, a guide wall opposite the side wall, and a rear wall connecting the side wall and the guide wall. The storage channels are each arranged above a transfer channel, wherein each transfer channel has a transport surface on which the goods can be transported to an output side for transferring the goods to the manipulator. A transport device transports a product lying on the transport surface in the direction of the output side.

The bearing channels are preferably arranged parallel to one another.

The goods intermediate storage device according to the invention allows an orderly storage of goods by being stacked one above the other in the storage channels. Here, similar or different goods can be stored in a warehouse channel. About the manipulator, the goods can be outsourced advantageously individually or in groups. The manipulator may transport the goods to an exit location or, for example, be part of an automatic warehouse to transfer the goods to their final storage position.

About the transport device, the goods can be pushed individually from the storage channels in an advantageous manner and get over the transfer channel to the manipulator.

Preferably, each bearing channel has a nominal width, wherein at least two of the plurality of bearing channels have a different nominal width. Under nominal width of the bearing channel is in the invention In a ground state of the storage channel usable width understood. A storable in the storage channel in the ground state goods can thus have a maximum of the nominal width corresponding width. For storage channels that have a variable, for example, reducible width for adaptation to different goods, the nominal width is the width of the storage channel, which has these in a ground state, for example, the maximum achievable width. In embodiments in which the width of a bearing channel is increased from the ground state, the nominal width is, for example, the minimum achievable width. By providing storage channels with different nominal width, goods of different sizes, for example of different widths, can thus advantageously be stored in the goods intermediate storage device.

It is preferably provided that some or all of the bearing channels each have a width adjustment device, by means of which the width of the respective bearing channel can be adapted to different product sizes, the sidewall of the respective bearing channel being movable in the direction of the guide wall of the respective bearing channel by the respective width adjustment device. About the adjustment of the side wall in the direction of the guide wall of a bearing channel, the width of the respective bearing channel is advantageously adjustable. Of course, it is also possible that the side wall is movable in a direction away from the guide wall. The side wall does not necessarily have to be adjusted over its entire height. Basically, there is also the possibility that only a portion of the respective storage channel is adjusted in width by means of Breitenverstelleinrichtung or that the adaptation to different sizes of goods takes place only in a section above the transport surface and above this section, the width of the storage channel, for example, is wider than a Width of a commodity. When adapting to the different product sizes, an adjustment to the widths of the goods can be made in principle. Of course, it is also possible that, depending on the storage direction of the goods an adjustment to the goods length or height of goods takes place. By providing bearing channels with a nominal width, wherein two or more bearing channels have a different nominal width and the provision of Breitenverstelleinrichtungen a very compact design of the Warenzwischenlagervorrichtung can be realized by the Breitenverstelleinrichtung provides only a relatively small change in width, for example a maximum of 20% the nominal width of the bearing channel. For the displacement of the side wall in the width direction of each bearing channel, a clearance is necessary in which the side wall for the width adjustment is displaceable. The free space is in the setting of widths of the storage channel smaller than the maximum possible width unused, but must be maintained for the adjustment to the maximum possible width. The provision of different nominal widths allows a flexible adaptation of the goods intermediate storage device to different goods, without each storage channel must be adjustable to a maximum width and each a correspondingly large space must be maintained. In other words, there may be provided some large nominal width storage channels which are adaptable for the adaptation of large size goods, and smaller nominal width storage channels which are adaptable to smaller size goods. Thus, a plurality of channels can be provided in a relatively small space, without leaving too much unused space for the width adjustment necessary in addition to a side wall space.

In a goods intermediate storage device with a width adjustment to one or more storage channels can be provided that the side wall of a storage channel is rotatably mounted at an end facing away from the transport surface, wherein the side wall for width adjustment of the bearing channel is pivotable. In other words, for width adjustment, the side wall is not displaced over its entire length, which extends in the height direction of the goods intermediate storage device, but merely pivoted. As a result, an adaptation of the bearing channel to a product size substantially in the lower region of the bearing channel and the side wall extends in an oblique upward direction. This has the advantage that the side wall is very long and thus the Warenzwischenlagervorrichtung can be made very high, without causing difficulties in the width adjustment of the bearing channel due to a parallel displacement of the side wall. The side wall is to be stored by the pivotable embodiment in an advantageous manner and only at a few points. For example, sufficient storage at the respective ends, for example, a pivot bearing at one end and an arcuate guide the pivoting movement of the side wall at the other end. In addition, a pivotable side wall can advantageously be actuated at the end facing the transport surface, so that the width adjustment device can be operated in an advantageous manner.

As an alternative to the pivotable mounting, it is also possible that the side wall is elastically bendable, wherein the side wall is clamped at its end facing away from the transport surface. Such a configuration has the advantage that no pivot bearing on the side wall is necessary. On the other hand, an elastically bendable material is necessary for the side wall. Furthermore, the adjustment of the side wall by the application of a force for elastic bending slightly more complex. However, an elastically bendable side wall has the advantage that it automatically returns to a basic position upon release of the width adjustment by the return action due to the elastic bending.

During the pivoting or bending of the side wall, this together with the guide wall forms a kind of funnel shape, so that the goods stacked in the storage channel are sorted by the transport device during removal of the lowermost goods and without tilting, and are guided in the direction of the transfer channel.

It is preferably provided that each side wall is connected in each case to a transfer channel side wall of the respective transfer channel assigned to the corresponding storage channel, the width of the transfer channel being adjustable via the adjusting device of the storage channel. The invention thus advantageously provides that the width of the transfer channel can also be adapted to the size of the goods. Thus, it is ensured that a commodity, which is transported along the transfer channel to the output side, not tilted. The fact that the width of the transfer channel is adjustable via the Breitenverstellvorrichtung of the bearing channel, the width of the transfer channel can be adjusted simultaneously advantageously with the width of the bearing channel.

Characterized in that the side wall of the bearing channel is connected to the transfer channel side wall, it is ensured that in the section of the storage channel directly above the transport surface and in the transfer channel, the same or approximately the same width is set. This ensures that the goods can be reliably guided and transported to the output side.

It is preferably provided that a sliding support is formed on the end remote from the side wall of the transfer channel side wall, which is supported on the transport surface. About the sliding support, the weight of the transfer channel side wall can be supported in an advantageous manner, at the same time by the configuration as a sliding support the transfer channel side wall can be moved in the width adjustment. The sliding support slides over the transport surface. The transport surface can thus be formed continuously in the region of a transfer channel, that is to say without recesses or the like for guiding the transfer channel side wall, so that there are no obstacles formed thereby for the goods sliding over the transport surface.

It can be provided that the sliding support has a height adjustment. This ensures that the transfer channel side wall is securely supported on the transport surface. The height adjustment device allows fine adjustment of the slide support. Due to the inherent weight of the side wall and transfer channel side wall, it may come to a deformation of this, in particular in a storage of the side wall in its upper Area. The deformation can cause the width adjustment is not reliable actuated. Due to the adjustable sliding support this can be counteracted.

Opposite the transfer channel side wall may be arranged a transfer channel guide wall. The transfer channel side wall and the transfer channel guide wall define the transfer channel laterally.

It is preferably provided that the width adjustment device has an actuating device which is displaceable in the longitudinal direction of the transfer channel, wherein the width-adjustment actuating device presses against the transfer channel side wall and / or side wall via at least one adjustment surface extending obliquely to the transfer channel side wall and / or side wall. Such a width adjustment has been found to be particularly advantageous, since by a simple actuation of the actuator in the longitudinal direction of the transfer channel width adjustment of the side wall or the transfer channel side wall can be done. Such an actuating device can also be designed to save space.

The adjustment surface may be formed by a slot in the actuator, wherein the transfer channel side wall and / or the side wall has a pin which engages in the slot. The adjustment is in this case formed by the boundary surfaces of the slot. In particular, the adjustment can run vertically. By forming the adjustment surface through a slot, the desired width adjustment is advantageously possible because the slot in which engages the pin, on both sides of the pin forms an adjustment surface and thus a guide on both sides of the pin. Thus, an adjustment in two adjustment directions in an advantageous manner possible without the need for a separate device for applying a return force. In principle, it can also be provided that the adjustment surface is formed by a wedge surface, wherein a counter surface is formed on the transfer channel side wall and / or the side wall. In such an embodiment is However, a return force necessary to effect in the width adjustment, a return of the side wall or the transfer channel side wall. An embodiment with an adjustment surface, which is formed by a wedge, is advantageously possible, for example, in the case of an elastically deformable side wall, the width adjustment being effected by the elastic deformation of the side wall, since a restoring force is provided by the elastic deformation.

In a preferred embodiment of the invention it is provided that in the transfer channel side wall and / or in the side wall, a clamping device is arranged, which presses a product arranged on the transport surface against the guide wall and / or against the transfer channel guide wall, which is preferably attached to the guide wall , This ensures that the goods arranged on the transport surface do not automatically slide on the transport surface in the direction of the discharge side, without the transport device moving the goods accordingly. The clamping device may, for example, be a leaf spring that protrudes from the transfer channel side wall and / or the side wall. Of course, it is also possible that the clamping device is arranged in the guide wall or the transfer channel guide wall and presses the goods against the side wall and / or transfer channel side wall.

The invention may provide that some or all of the transfer channels each have a height adjustment device, via which the height of the respective transfer channel in at least one section of the transfer channel can be adapted to different product sizes. Thus, it can be ensured that only one lying on the transport surface goods is transported to the output end of the transfer channel by means of the transport device. By adjusting the height by means of the height adjustment not only goods of a product size can be stored in a storage channel, but after the adjustment of the height and stack of goods with a different product size. The height adjustment device may have a plate which is arranged on the rear wall of the transfer channel associated with the bearing channel and is adjustable in the direction of the transport surface. For example, the plate can be guided over a slot. In this way, a height adjustment in a particularly simple manner can be realized.

The width adjustment device and / or the height adjustment device are advantageously operable from the front side of the goods intermediate storage device, that is to say from the side remote from the delivery side. For this purpose, for example, the actuating device may comprise an actuating element which is guided through a recess in the rear wall, for example a screw. With a similar actuator and the height adjustment can be operated.

It is preferably provided that the transport surface of some or all of the transfer channels is divided into two parts and consists of a bottom element, which is at least partially below the respective storage channel and a chute element, wherein the chute member has a greater inclination relative to the horizontal than the bottom element. This has the advantage that goods which are conveyed onto the chute element move independently in the direction of the discharge side due to the inclination of the chute element. The transport device must thus move only one arranged on the bottom element goods, so that the way that must be covered driven by the goods driven by the transport device, can be kept short. As a result, the transport device can be made compact and short in length.

It is preferably provided that the transport surfaces, preferably the bottom elements, each having an elongated recess, wherein the transport device comprises a below several of the transport surfaces, preferably the bottom elements, movable Auslagerungsschlitten, wherein the Auslagerungsschlitten has a Auslagerseinrichtung having a projection in each one of Recesses to outsource one engages the corresponding transport surfaces, preferably on a corresponding bottom element, resting product. In other words, it can be provided in the intermediate goods storage device according to the invention that the transport device can serve several of the storage channels or transfer channels. For this purpose, the transport device is moved below the transport surfaces, preferably the bottom elements, the transfer channels. To outsource a product of a storage channel, the transport device is moved to the corresponding storage channel and can outsource the corresponding product by means of the removal device. As a result, a cost-effective construction is made possible in the case of the intermediate goods storage device according to the invention, since a transport device serves a plurality of storage channels or transfer channels and thus avoids the expense of a large number of transport devices.

It is preferably provided that the removal slide is movably mounted on a rail arranged under a plurality of the transport surfaces, preferably under a plurality of the floor elements. In this way, the paging carriage is advantageously below the transport surfaces, preferably below the floor elements, movable. The rail may for example be formed by a plate. In this way, the removal slide can be performed on the rail in an advantageous manner by the rail formed as a plate at least partially surrounds.

The invention may advantageously provide that the removal device has a circumferential cam band, wherein the projection is formed by a cam of the cam band. By means of a cam belt can be outsourced on the transport surfaces, preferably on the floor elements, resting goods in a particularly advantageous manner. In addition, the removal device with a revolving cam belt has the advantage that it can be driven in a simple manner with a rotary drive. As a result, a structurally simple embodiment of the goods intermediate storage device is possible. On the transport surfaces, preferably the bottom elements, facing side of the paging slide can be arranged on opposite sides of the cam belt extending parallel to the cam band Klemmschutzleisten, each on their transport surfaces, preferably the floor elements, facing side of the cam belt in the longitudinal direction of the rail to the outside fall off. In the transport areas or the floor elements, where the transport device is not at a time, an operator can accidentally reach into the recess for the Auslagerseinrichtung. Now, if the retrieval slide is moved in the direction of this transport surface or this bottom element, there is a risk that the inserted into the recess body part of the operator, such as a finger, is trapped or injured. By providing the clamping strips, it is ensured that, during the process of the removal slide, one of the clamping strips is pushed under the corresponding recess under the corresponding body part, and this is thus lifted out of the recess. As a result, injuries are largely avoided.

The invention may advantageously provide that the cam band has a plurality of cams. A cam lobe with several cams has the advantage that when several goods of a storage channel are to be stored one behind the other, this can be done at a higher speed, because the cam belt does not have to completely circulate before the next product can be outsourced by the cam.

It is preferably provided that the distance A of two successive cams is selected such that the cam belt engages in a displacement position with no cam in one of the recesses of the bottom elements. The removal slide can thus be moved from one floor element to another floor element only when no cam engages in a recess, since the cam otherwise gets caught in the recess. The positioning position ensures that the removal carriage can be moved. Preferably, the distance between two cams greater than the length of a portion of the cam band extending directly below the bottom member and preferably parallel to the bottom member. A cam, which is located in this section of the cam belt, projects from the cam belt in the direction of the bottom element and engages in the recess. If the distance A between the cams is greater than the length of this portion of the cam belt ensures that the cams can be moved to the travel position in which the cams are already submerged relative to the bottom plate. Preferably, the distance A between two cams is at least 1.1 times the length of the part of the cam band extending directly below the bottom element. For example, in a cam belt, which is guided over deflecting paths of deflection rollers, wherein a first guide roller and a second guide roller guide the cam belt to form the directly below the bottom member extending portion of the cam belt, the distance A of the cam may be greater than the distance D of Axes of the first and second pulleys. Preferably, the cam A applies> (D + V ^ -n-Ri + ^1/2 · P · R ₂₎ for the distance A, wherein Ri and R ₂ denote the radii of the reversal tracks of the first and second pulleys. It is thereby achieved that, for example, for the displacement position, the cams can be brought into a position extending parallel to the floor element.

In a cam belt with two cams, the cams are preferably arranged in both directions at the same distance A.

Distance A of the cams is understood in the context of the invention to extend between two cams length of the cam belt.

By providing the distance according to the invention between two successive cams, it can be ensured that in a travel position of the cam belt, none of the cams are located in the recess in the bottom element and thus a method of the removal slide is possible. Preferably, the transport device has a motor-driven belt drive for the removal slide, which is arranged below the rail, wherein the removal slide partially surrounds the rail. About such a construction of the retrieval slide is drivable in a particularly advantageous manner.

The rail is preferably mounted at both ends and thus self-supporting. This ensures that the removal slide can be moved freely over the entire length of the rail and no complicated construction due to additional supports of the rail is necessary. The rail can be profiled for this purpose, for example, whereby the stability of the rail is increased and sagging of the rail due to its own weight is avoided.

The design of the transport device with a motor-driven belt drive for the paging carriage also has the advantage that a drive of the paging carriage can be done without the paging carriage has to carry the drive. As a result, the removal slide can be made very compact. In principle, however, it is also possible for the removal carriage to have a traveling drive which cooperates, for example, with a threaded spindle or rack arranged on the rail.

It is preferably provided that a mechanical emergency shut-off valve is arranged on the removal slide on the side facing the operator and / or a side facing away from the operator, which actuates a mechanical lock of the removal slide and / or a power interruption of a drive motor of the removal slide. The side of the paging carriage facing away from the operator is the side facing the discharge side and the side facing the operator is the side of the goods intermediate storage device facing away from the delivery side. In the operation of the goods intermediate storage device according to the invention, it may occur that an operator accidentally with a body part, such as with his hand, in an area near the longitudinal edges of the rail and thus in the travel of the paging carriage. When the pusher carriage is moved in this case, the paging carriage abuts against the body part of the operator with the mechanical emergency stop pusher, and the paving carriage is immediately stopped by the power interruption and / or mechanical pawl. This avoids injuries. The mechanical lock can intervene, for example, in the rail.

Preferably, the Notabschaltschieber is actuated on both sides, so that the Notabschaltschieber can be triggered regardless of the direction of travel of the paging carriage.

The emergency shut-off valve preferably has a return spring, which returns the emergency shut-off slide to a basic position when the mechanical lock is unlocked. This will ensure that once the mechanical lock is released, the emergency shut-off valve will be "in focus" by returning it to its home position and will function by re-moving the emergency exit skid. In one embodiment of Notabschaltschiebers only for power interruption of the drive motor can be provided that the Notabschaltschieber is manually returned to its basic position.

The invention may further provide that at an upper end of the bearing channels sensors are provided which sense a level of the bearing channels. About a computer-aided warehouse management system, for example, the level of the storage channels can be determined and specified when refilling a storage channel with goods is necessary. In principle, a sensor can be arranged on each bearing channel. It is also possible that at the upper ends of the bearing channels, a rail is arranged, via which a sensor is movable, so that with one sensor, the level of several Storage channels can be monitored. It can also be provided that at least one sensor is arranged on the removal carriage, which senses whether a product is arranged in a storage channel. By way of example, it can be ascertained during a paging operation that the last goods have been removed, so that the cam belt can be stopped. The at least one sensor can be designed as an optical sensor and "look", for example, through corresponding holes in the transport surface, preferably the bottom element. It can also be provided that the at least one sensor is arranged on a part of the paging carriage located below the rail. In the embodiment of the sensor as an optical sensor, in this case, the rail also has holes which are aligned with the holes in the transport surface.

It is preferably provided that on the output side each transfer channel has a safety flap. Also, several transfer channels may have a common safety flap. The or each safety flap, for example, serve as a stop for goods that are transported in the direction of the output side. Once the manipulator has moved to the discharge end of a transfer channel, the safety flap can be opened to transfer the goods to the manipulator. Since manipulators of goods flow systems are often movable at high speed, the safety flap serves as protection, so that the operator can not reach with his hand through the transfer channel in the travel of the manipulator. Thus injuries are avoided. In addition to the security flap, the transfer channel can also have a separate stop for the goods, so that when the goods are transferred to the manipulator, the security flap is first opened, before the goods can then be transferred to the manipulator via removal of the stop. The safety flap can for example be unfolded, pivoted on an arcuate path or linearly displaced.

On the output side, the transfer channels can have sensors that ensure that the goods have been completely transferred to the manipulator is, so that the manipulator can be moved, without causing jamming due to stuck between the transfer channel and the manipulator goods.

In the goods intermediate storage device according to the invention, it is basically possible that several goods are transferred from a transfer channel to the manipulator. The manipulator is designed such that it can accommodate several goods. The goods can be outsourced via the transport device initially from the storage channel and remain briefly in the chute element. When the manipulator subsequently stops at the discharge side of the corresponding transfer channel, the goods can slide out of the chute element onto the manipulator. It is also possible that the goods are outsourced from the storage channel when the manipulator is already positioned on the output side of the corresponding transfer channel and, if necessary, the safety flap is already open. By means of the transport device goods are then outsourced at a high frequency and slide over the chute element on the manipulator. There is also the possibility that the manipulator has several parallel transport places, so that the manipulator can receive goods from several transfer channels simultaneously.

The invention will be explained in more detail with reference to the following drawings. Show it :

FIGS. 3 to 3b are schematic detailed representations of the width and height adjustment of a storage channel of the invented goods storage device according to the invention,

FIGS. 4

to 6 are schematic detailed representations of the transport device of the goods intermediate storage device according to the invention and

7 shows a rear view of the goods intermediate storage device according to the invention.

In Fig. 1, a Warenzwischenlagervorrichtung invention 1 is shown schematically in an overall view. The Warenenzwlagerlager- device 1 has a plurality of bearing channels 3, which are arranged parallel to each other. The bearing channels 3 partially have a different nominal width. The bearing channel 3a shown on the far right in FIG. 1 has, for example, a significantly larger nominal width than the bearing channel 3b shown on the leftmost side. The nominal width determines, for example, the maximum width of a product that can be received in the corresponding storage channel 3.

As is apparent from Fig. 1, the goods intermediate storage device may be modular and be composed of individual elements la, lb of different width, for example. In the exemplary embodiment illustrated in FIG. 1, the module 1a has, for example, 13 bearing channels 3, whereas the module 1b has 9 bearing channels. As a result, the goods intermediate storage device 1 according to the invention is flexibly expandable and adaptable to needs.

The bearing channels 3 are each arranged above a transfer channel 4.

The bearing channels 3 each have a side wall 5, a side wall of the opposite guide wall 7 and a side wall 5 and the Guide wall 7 connecting rear wall 9. As best seen in Fig. 2, in which a detailed representation of several parallel bearing channels 3 is shown, the goods intermediate storage device 1 for at least some of the storage channels 3, a width adjustment device 11, via which the width of the corresponding storage channel 3 is adaptable to different product sizes. For this purpose, the side wall 5 is moved in the direction of the guide wall 7 of the respective bearing channel 3 by means of the width adjustment device 11 (see arrow).

The side wall 5 is rotatably mounted on the end facing away from the transfer channel 4 end 5a, so that the side wall 5 for width adjustment of the bearing channel 3 is pivotable. Thus, at least a portion of the storage channel 3 is adjusted immediately above the transfer channel 4 to the goods size. The displaced side wall 5 together with the guide wall 7 forms a kind of funnel shape, so that goods stacked in the storage channel 3 can advantageously advance through the side wall 5 and the guide wall 7 in the direction of the transfer channel without tilting.

As is apparent from Fig. 2, the side walls 5 extend in the unadjusted ground state almost parallel to the guide wall 7 of the adjacent storage channel 3. About the width adjustment is only a relatively small width adjustment, for example, a maximum of 20% of the nominal width. This has the consequence that when adjusting the width adjustment 11 by pivoting the side wall 5 of the remaining between the side wall 5 and the adjacent guide wall 7 space 13, which must be kept free for a provision of the side wall 5, is relatively low, so that a total a very compact intermediate goods storage device can be created. In other words, without the provision of storage channels with different nominal widths, all storage channels would have to be designed for the maximum goods size in order to be able to receive goods of this size, even if often only goods with smaller product sizes are stored. Such a configuration would require unused space, which the present invention avoids. On the rear wall 9 of the bearing channels 3 each have a height adjustment device 15 is arranged, via which the height of the respective transfer channel 4 is adjustable. The height adjustment device 15 has for this purpose a plate 17 which can be moved parallel to the rear wall 9 and the height of the transfer channel 4 at least partially limited. Thereby, the transfer channel 4 can be adapted to different sizes of goods, so that it is ensured that in a removal of a commodity through the transfer channel in each case only one commodity is moved.

In the Fign. 3 to 3b, detailed illustrations of the width adjustment device 11 are shown. At the transfer channel 4 facing the lower end 5b of the side wall 5, a transfer channel side wall 19 is attached. The transfer channel side wall 19, together with a transfer channel guide wall, not shown, delimits the transfer channel 4 on both sides. The transfer channel side wall 19 is designed to be movable together with the side wall 5, so that over the width adjustment device 11 in addition to the width of the storage channel 3 and the width of the transfer channel 4 can be adjusted.

As is apparent from Fig. 3, the transfer channel 4 has a transport surface 21 which is divided into two parts. The transport surface 21 consists on the one hand of a bottom element 23, which forms the bottom of the storage channel 3 and a chute 25, which has a greater inclination relative to the horizontal than the bottom element 23. Goods to be outsourced from the storage channel 3, on the Floor element 23 are pushed to get to the slide element 25. On the slide element 25, the goods then slip due to gravity to the output side.

In Fig. 3a, the width adjustment 11 and the height adjustment 15 are shown in detail. The width adjustment device 11 has an actuating device 27 which is displaceable in the longitudinal direction of the transfer channel 4. For this purpose, an actuating element 29 can be actuated. The actuating device 27 has an adjusting surface 31 running obliquely to the transfer channel side wall 19, which in the case of FIG the fig. 3 to 3a illustrated embodiment is formed by a slot 33. In the slot 33, a pin 35 is guided, which is part of the transfer channel side wall 19. Upon actuation of the actuator 27 in the longitudinal direction of the transfer channel 4, the transfer channel side wall 19 and thus the side wall 5 is moved transversely to the longitudinal direction of the transfer channel 4, so that a width adjustment is possible. The embodiment of Betätigungsvorrichtrung 27 with a slot 33 in which a pin 35 is guided, provides two parallel Verstellflächen 31 so that upon actuation of the actuator 27 in the reverse direction, the transfer channel side wall 19 and thus the side wall 5 is returned in the other direction , As a result, a particularly advantageous adjustment is possible.

The height adjustment device 15 also has an actuating element 37 in the form of a screw. The plate 17 has a slot 39 through which the actuator 37 of the height adjustment device 15 is guided. By releasing the actuating element, the plate 17 can be moved to adjust the height.

The configuration of the height adjustment device 15 and the width adjustment device 11 have the advantage that they can be operated by a simple tool from the operator facing side of the goods intermediate storage device 1 according to the invention. The operator-facing side is, for example, the side to which one looks in FIG.

As is apparent from Fig. 3b, the transfer channel side wall 19 is supported on the side remote from the side wall 5 end via a sliding support 41. The slide support 41 in this case has a height adjustment device 43, which is shown in Fig. 3b. The height adjustment device 43 is formed by a screw which has a sliding head 45 at its lower end. By means of the sliding head 45, the sliding support 41 can slide over the chute element 25 of the transport surface 21 in the width adjustment. Since the side wall 5 is mounted at its upper end 5a, it may cause deformation of the side wall. 5 and the transfer channel side wall 19 come, the function of

Width adjustment can affect. By the height adjustment device 43 of the slide support 41 a fine adjustment is possible, so that the

Transfer channel side wall 19 is always securely supported and reliable operation of the width adjustment device 11 is ensured.

As can be seen from FIG. 3 a, the transfer channel side wall 19 has a clamping device 46 which presses a product lying on the transport surface 21 against the transfer channel guide wall. This ensures that no product is unintentionally conveyed by the bottom element 23 of the transport surface 21 in the direction of the chute element 25.

The goods intermediate storage device 1 according to the invention also has a transport device 47, which is shown in Fig. 4 in detail. FIG. 4 also shows the transport surface 21, the side walls 5, guide walls 7, transfer channel side walls 19 and transfer channel guide walls not being shown for clarity. The guide walls 7 and

Transfer channel guide walls extend approximately along the illustrated mounting holes in the respective transport surface 21. In the bottom element 23 of the transport surface 21 each elongated recesses 49 are arranged. These are in the assembled state of the goods intermediate storage device 1 approximately below the plate 17 of

Height adjustment 15 a transfer channel 4 arranged so that it is ensured that goods with the smallest dimensions reliably outsourced individually, d. H. from a floor member 23 to the associated chute member 25 can be conveyed.

Below the bottom elements 23 of the transfer channels 4 is a

Removal carriage 51 of the transport device 47 movable. For this purpose, a rail 53, which is shown in Fig. 5, arranged below the bottom elements 23. The removal slide 51 surrounds the rail 53, which is formed as a profile plate, at least partially and is freely movable on the rail 53. For this, the rail 53 is cantilevered at both ends. To drive the paging carriage 51, a motor-driven belt drive is arranged below the rail 53, which is not shown in Fig. 5. Via the belt drive, the removal carriage 51 can be driven in a particularly advantageous manner, since the drive does not have to be carried along by the removal carriage 51.

As shown in FIGS. 4 to 6, the unloading carriage 51 has a revolving cam belt 55. The cam belt is part of a retrieval device of the retrieval carriage 51. After moving the retrieval carriage 51 under a recess 49, the cam belt 55 can be driven, so that a projection in the form of a cam 57 dives through the recess 49 and projects over the transport surface 21 upwards. As a result, the cam 57 can press against a product lying on the transport surface 21 and convey it in the direction of the delivery side of the goods intermediate storage device 1. At the end of the recess 49, the cam 57 emerges during the circulation of the cam belt 55, so that it no longer protrudes through the recess 49. As a result, a method of the removal carriage 51 is possible.

The cam belt 55 may have a plurality of cams 57, for example two cams 57. The distance A of two successive cams 57 is selected such that the cam belt 55 engages in a displacement position with no cam in the recess 49.

In the displacement position it is ensured that the removal carriage 51 can be moved without the cam 57 getting caught in the recess 49.

The distance A, not shown, between two cams 57 may, for example, be greater than the length of a section 55a of the cam band 55 extending directly below the bottom element 23 and parallel to the bottom element 23. A cam 57, which is in this section 55a of the Cam belt 55 is, projects from the cam belt 55 in the direction of the bottom element 23 and engages in the recess 49 a. If the distance A between the cams 57 is greater than the length of this portion 55a of the cam belt 55, the cam belt 55 can be moved to the displacement position in which the cams 57 are already submerged relative to the bottom element 23.

By providing a plurality of cams 57 on a cam belt 55, a faster outsourcing of goods can take place since the cam belt 55 does not have to completely circulate before the next product can be displaced by means of the cam 57 on the transport surface 21 for removal.

For example, as shown in FIG. 4, an operator could insert his finger into a recess 49 and then touch the underlying rail 53. In a method of the paging slide 51, injuries could be caused by, for example, the cam belt 55. Therefore, as shown in FIG. 6, laterally of the cam belt 55, clamping guard rails 59 are arranged on the unloading carriage 51, which are parallel to the cam belt 55. The Klemmschutzleisten 59 fall from the outside, so that they form a kind of ramp. An operator's finger placed on the rail 53 is therefore lifted by the clamping protection strips 59 and pushed out of the recess 49, so that the risk of injury is reduced.

Furthermore, the transport device 47 has a arranged on the Auslagerungsschlitten 51 mechanical Notabschaltschieber 61. This is, as shown in Fig. 4, movable on both sides. When an operator now grips the traverse area of the paging carriage 51 adjacent to the rail 53, the emergency shut-off valve 61 abuts against the corresponding body part of the operator and is triggered. The Notabschaltschieber 61 acts together with a mechanical lock 63 and a power interruption, not shown, of the drive motor. As a result, the unloading carriage 51 is stopped immediately. The mechanical lock 63 engages after being triggered from below into the rail 53. The mechanical lock 63 can then be released manually. The emergency shut-off also has a return spring 66 shown schematically, via which it is returned after unlocking the mechanical lock 63 in a basic position.

In Fig. 7, the invented goods storage device 1 is shown from its rear side. On the output side 65 moves a manipulator 67 to which the outsourced goods can be transferred. The manipulator 67 moves the outsourced goods either to an issuing office or transfers them, for example, to an automatic warehouse. The transfer channels 4 are closed at the output side 65 by means of a safety flap 69. This serves as protection that an operator who grips with his hand through the transfer channel 4 can not get into the travel of the manipulator 67. The safety flap 69 may be driven in translation, for example, so that it is lifted or, for example, guided along a curved path, so that it is pivotable.

At the end facing the output side 65, the transfer channels 4 may comprise sensors, not shown, which sense whether a product is completely transferred to the manipulator 67 in order to prevent goods from jamming between the manipulator 67 and the delivery end of the transfer channel 4.

Furthermore, at least one sensor, not shown, can be arranged on the removal carriage 51, via which it can be sensed whether goods are located in one of the storage channels 3. The sensor is arranged, for example, on a part of the paging slide 51 located below the rail 53 and is designed as an optical sensor. In the rail 53 sensor holes 54 are formed through which the sensor can look. Further, in the bottom member 23 second sensor holes 54 a are arranged, which are aligned with the sensor holes 54 in the rail 53. If the removal carriage 51 is arranged below a storage channel 3, the sensor can be replaced by the Sensor holes 54,54a sense whether goods in the storage channel 3 is present. In particular, in a paging operation can thus be determined when the last goods has been outsourced, so that the cam belt 55 can be stopped immediately after removal of the last goods.
