The invention relates to the field of metal forming and can be used for mecanized. loading with small-sized flat blanks of punching machines. Closest to the invention is a hopper for flat blanks, comprising a base, a housing with an annular cavity, a vibratory drive with an annular groove and size. A movable disc in it, a spring rod with an adjustable active length, connected at one end to the casing Ct. 3. The disadvantage of the known hopper is insufficient reliability. due to the fact that a ratchet mechanism was used for its rotation, the vibratory drive is connected with the base; The aim of the invention is to increase reliability. The aim is achieved in that a hopper for flat blanks comprising a base, a housing with an annular cavity, a vibration drive with an annular groove and placed. in it, a movable disk, a pinning rod with an adjustable active length, one end connected to the housing, is provided with a hollow annular insert freely placed in the annular cavity of the housing, the other end of the spring rod is fastened directly on the base, and the vibration drive is rigidly fixed on the case. Figure 1 shows the bunker dl. flat blanks, longitudinal section in figure 2 - section aa in figure 1. . The hopper for flat workpieces comprises a housing 1 with a horizontal annular cavity 2, in which an annular insert 3 is freely placed with a gap between the side walls 4 and 5 of the horizontal strip 2 and the walls 6 and 7 of the hollow annular insert 3, in which the insert 8 is located on which the bulk of the blanks 9 is placed, the upper layer 10 of which is horizontal during the operation of the bunker. The housing 1 is fixed on the upper end of the spring rod 11, the lower end of which is fixed on the base 12. The stiffness of the spring rod 11 is adjustable: it changes by changing its active length. Vibration drive 13 is rigidly fixed on the chrpus 1, in the ring groove 14 of which there are gaps 5 and the rolling body is placed in the form of a disk 15, moving along the ring groove 14 along arrow B. Vibrating drive ring 14 is connected by channels 16 and 17. with a source of compressed air as well. channel 18 - with the atmosphere. The hopper for flat blanks works in an efficient manner. The compressed air arriving from the source through channels 16 and 17 into the annular groove 14 moves along arrow B to the disk 15. And it is released into the atmosphere through Channel 1.8. As a result of the movement of the disk 15, the active mass, including the vibration drive 13, the housing 1, the hollow annular insert 3, the insert 8 and the channel of the blanks 9, oscillates annularly, as a result of which the upper blanks of the pile 10 layer 9 move in mutual directions the smallest resistances are arranged in horizontal layers. Such an arrangement of the upper blanks of the layer 10 is advantageous for capturing them. for example, a vacuum gripping body (not shown). Due to the gaps between the walls 4 and 5 of the horizontal annular cavity 2 and the walls 6 and 7 of the hollow annular insert 3, when working with an offset 2e in the annular cavity 2, the next blanks of the upper layer 10 rotate and feed under the vacuum gripper. rotation of the hollow annular insert 3 and the amplitude of the annular oscillations of the housing 1 is provided by varying the pressure of the compressed air entering the annular groove 14 and changing. active length o. spring rod 1 1. The hopper is intended for loading blanks with a thickness of 0.05-0.5 mm with dimensions in the plan from 5 to 12. The proposed bunker is reliable in operation.
