Definitions

  • the invention relates to a magazine for plate-shaped objects, which is oriented essentially horizontally and in which the plate-shaped objects are arranged next to one another to form a stack, preferably with a slight inclination to the rear, with devices associated with the magazine for advancing the stack to its removal point. which is associated with a removal device which removes a plate-shaped object individually, and with a holding-down device which is arranged above the stack in the region of the removal point and acts on the objects from above.
  • Magazines with devices for removing plate-shaped objects from a column of such objects accommodated in a magazine are, for example, from AT-B. 241 565, 329 124 and 352 198 are known.
  • the plate-shaped objects are accommodated one above the other in them.
  • This superimposed arrangement of the plate-shaped objects in the stack has the result that considerable friction forces occur, particularly in the case of larger stacks, when removing the bottom plate-shaped object in each case, which hinder the separation of the plate-shaped objects.
  • This is particularly the case when the plate-shaped objects accommodated in the magazine are plates or separators for accumulators.
  • AT-B 352 198 it has therefore already been proposed to provide a clamping device that can be actuated independently of the removal devices at a distance above the removal point in order to absorb the weight of the stack during the removal process.
  • a magazine of the type mentioned is known for example from GB- B 1 581 764.
  • the hold-down device known from GB-B 1 581 764 can be moved up and down in a movement plane which is invariable with respect to the magazine, so that the end of the stack of plate-shaped objects facing the removal point must be precisely defined so that the known hold-down device also fulfill the function assigned to it can.
  • retractable retaining plates are provided in the magazine known from GB-B 1 581 764 at the end of the same on the removal side.
  • retention plates hinder the removal process.
  • a precisely coordinated interplay of the movements of the removal gripper of the retaining plates and the holding-down device is required.
  • the invention has for its object to provide a magazine of the type mentioned, in which the hold-down device aligns itself automatically with respect to the removal end of the stack of plate-shaped objects accommodated in the magazine.
  • this is achieved in that the hold-down device is suspended in an oscillating manner about a horizontal axis oriented transversely to the longitudinal extent of the magazine, and in that the hold-down device has a stop to be placed at the front end of the stack, which is spaced from the hold-down device of the hold-down device essentially by the thickness of a plate-shaped object .
  • the inventive design of the hold-down device adapts itself automatically and without any control to the removal end of the stack of plate-shaped objects.
  • the distance between the stop and the hold-down device of the hold-down device provided according to the invention also reliably ensures in the invention without any special control that the hold-down device is arranged exactly above the upper edge of the second plate-shaped object as seen from the removal-side end of the stack.
  • the hold-down device known from GB-B 1 581 764 which acts on a plurality of plate-shaped objects arranged at the removal end of the magazine, this reliably ensures that only one plate-shaped object is removed at a time. This is particularly important in the production of plate stacks in the course of the production of batteries.
  • the preferred area of application of the magazine according to the invention is therefore also its use in devices for producing plate stacks from positive and negative battery plates and the separators to be arranged between them.
  • Several magazines according to the invention can be arranged next to one another in a device of this type, the magazines, for example, containing positive and negative battery plates on the one hand.
  • the stop is designed as a leaf spring. Since the stop has no other task than aligning the hold-down device above the second plate-shaped object, the leaf spring can be made soft so that it does not impede the removal process without impairing its function.
  • the stop is designed as a stop which can be pulled upwards.
  • This embodiment is preferably used for removal grippers which remove the foremost plate-shaped object at least at the beginning of the removal process with a movement path oriented parallel to the longitudinal extent of the magazine.
  • the hold-down device controlled by the stop of the hold-down device, can align itself again above the second plate-shaped object after a removal process, it has to be temporarily pulled upwards away from the plate stack.
  • An embodiment of the invention has proven itself for this purpose, according to which the hold-down device can be pushed back and forth by a pressure medium cylinder.
  • the stop can be pushed back and forth by a pressure medium cylinder.
  • the hold-down device and the stop are assigned a common actuating member for the opposite movement of the stop and hold-down device.
  • This embodiment has the advantage that only a single actuating element, for example a pressure medium cylinder, is required to carry out the opposite movements of the stop and hold-down device.
  • the hold-down device, the stop and the actuating device (s) are mounted on a pivotable plate, which in its upper end region has a cantilever arm, possibly loaded by a weight, from the side opposite the stack sticking out of the plate.
  • This embodiment has the advantage that the hold-down device swings back into its functional position quickly after the removal process has taken place and when the hold-down device is retracted upwards.
  • the contact pressure of the stop against the front ie. H. end of the stack on the removal side, by selecting the size, the weight or by moving the same relative to the delivery arm to the most favorable value.
  • the reliable function of the magazine according to the invention is supported by an embodiment of the invention, according to which the device for advancing the stack in the magazine has endless conveyor chains or conveyor belts associated with the two vertical edges of the plate-shaped objects forming the stack, with resilient drivers which rest on the vertical side surfaces of the stack , are trained.
  • the device for advancing the stack in the magazine has endless conveyor chains or conveyor belts associated with the two vertical edges of the plate-shaped objects forming the stack, with resilient drivers which rest on the vertical side surfaces of the stack , are trained.
  • the driver flaps of the conveyor chains or conveyor belts are designed to be resilient, the magazine can be loaded with plate-shaped objects by simply inserting stacks of plate-shaped objects from the end of the magazine opposite the removal point.
  • This insertion of the plate-shaped objects into the magazine is particularly simple if the insertion end of the magazine is assigned a slide-in carriage for a package of plate-shaped objects, the surface of which facing the package is inclined to the rear.
  • the lateral distance of the conveyor chains or conveyor belts and of the guide rails assigned to the high edges of the plate-shaped objects forming the stack can be changed is. It has proven itself in the context of the invention if the guide rails arranged on both sides of the magazine and the conveyor chains or conveyor belts are arranged on slides which can be displaced transversely to the longitudinal extent of the magazine.
  • the slides are slidably guided on rails oriented transversely to the longitudinal extent of the magazine and via handlebars with one in the middle of the magazine arranged, for example pneumatically operated actuator are coupled.
  • the conveyor chains or conveyor belts are deflected out of engagement with the plate-shaped objects in front of the removal point of the magazine.
  • a particularly suitable within the scope of the invention is characterized in that the removal device is pivotably mounted on the frame of the magazine via pairs of connecting rods. With such a suspension of the removal device, it is useful if the handlebars engaging at the lower end of the removal device in the removal position on Frame are mounted higher up than the handlebars articulated at the other end of the removal device. As a result, the removal device is moved from its essentially to the side removal position into the downward-facing, associated with the conveyor device without additional control means Delivery position tilted.
