Abstract

FIELD OF THE INVENTION The invention relates to a lifting and transport machinery, namely, devices for loading and unloading a conveyor, and improves productivity. On the movable from the actuator 3 relative to the fixed frame / P / 1 of the upper tier P 2, a lifting unit P 4 is installed. Under P 1 there is an additional fixed P 6 and a movable set relative to the latter from the actuator 8 an additional P 7 with an additional lifting P 9. Before and from the rear P 6 is equipped with lifting tables / C / 11, 13 passing through P 2.7. Above P 1, suspensions 15 of the overhead conveyor pass. The device manipulates pallets / P / 16-21. As the suspension 15 approaches, P 4.9 is lifted and P 2 moves to the right and P 7 moves to the left. In this case, P 18 occupies the right end of P 2, P 16 becomes in place of the suspension 15, and P 17 is placed under P 1. In addition, P 21 is placed above C 11, and P 19, 20 - under P 6. When lowering P 4 , 9, P 16 is mounted on suspension 15, P 17 on P 1, P 21 on C 11, and P 19, 20 on P 6. When lifting C 13 and 11 P 21, they are placed at the level of the upper tier, while P 19 is set to P 13. The P 2 moves left and its left end is under P 21. When C 11 is lowered, P 4 is set to P 21, and when C 13 is lowered, P 18 mounted on it is placed at the level of the lower rus . 5 il.

FIELD OF THE INVENTION The invention relates to lifting and transport machinery, namely, devices for loading and unloading an overhead conveyor.

The purpose of the invention is to increase productivity,

Fig. 1-5 schematically shows the proposed loading-loading device in various phases of the operating cycle.

The device contains two equipment rus. The equipment of the upper tier includes a fixed frame 1, a frame 2 movable along it with an input of 3 movements and an articulated frame 4 mounted on the last lifting frame with a lifting drive 5. The equipment of the lower tier includes an additional fixed frame 6, an additional movable frame 7 with a drive of 8 movement and an additional lift frame 9 with a drive of 10 lifting about it. A lifting table 11 with a drive of lift 12 S is installed before the frame 6 and behind the frame 6 is installed -lift table 13 with a drive 14, With the help of a loading and unloading device load suspension 15 overhead conveyor. The device manipulates with pallets 56-2

The device operates in the following way.

Starting position (Fig, 1). The movable frame 2 of the upper tier is in the left position. Additional movable frame 7 lower russia is in the right position. Lifting frames 4 and 9 are lowered. On frame 4, pallet 16 is installed, Lifting tables 11 and 13 are lowered, and pallet 19 is mounted on table 13,

Loading the suspension 15 and the lifting table 11 (FIG. 2). When approaching the suspension 15 of the overhead conveyor, the drives 5 and 10 of the lifting frames 4 and 9 turn on to the loading and unloading device. When the lifting frames reach the pallet overload level, the drives 5 and 10 turn off . Pallets 17 and 18 are mounted on frame 4, and pallets 19-21 are placed on additional frame 9. Drives 3 and 8 of moving frames 2 and 7 are turned on, Frame 2 is moved to the right to failure, and drive 3 is turned off. The pallets are moved in the same way that 18 is occupied by the right

the frame 2, the pallet 16 becomes the suspension 15, and the pallet 17 over the fixed frame 1, the additional movable frame 7 moves to the left until failure, and its drive 8 is turned off, the pallets are placed as follows: the pallet 21 over the lifting table 11 , and pallets 19 and 20 are above the additional fixed frame 6. Drives 5 and 10 are activated to lower pallets. Pallet 16 lowers Aa suspension 15, pallet 17 to frame U, pallet 21 to mobile table M, and pallets 19 and 20 to additional fixed frame 6. Suspension. And the conveyor moves suspension 15 from the place of overload.

Overloading pallets 18 to the lower rus, pallets 21 - to the upper one. The actuator 12 is turned on to the table P with the pallet 2S rises to the level of the upper tier. Drive 12 is turned off. The actuator 14 is turned on and the GB table also rises to the level of the upper tier. Drive 4 is turned off. The actuator 3 is turned on, and the movable frame 2 moves to the left to failure. The pallet 18 remains on the table 13 j postddon 7 - on the frame 1 "and the left end of the frame 2 fits under the pallet 2 i on the table 1 1 (Fig. 4)." The drives 12 and 14 turn on. Table 11 is lowered onto the lower floor; as is the table 13 with the pallet 18 (Fig. 5), the Pallet 21 is mounted on the lifting frame 4, and the pallet 18 remains on the table 13. Then the operation cycle repeats.
