SU134372A1 - Semiautomatic line for the primary processing of hides for salt cleaning, weighing, visual inspection and stacking on racks - Google Patents

Description

The proposed semi-automatic line for the primary processing of raw materials for salt cleaning, weighing, visual inspection and laying of hides on shelves facilitates the working conditions of workers and increases productivity.

The semi-automatic line is made in the form of carriages automatically stopped at the place of unloading, mixed by a conveyor at a given address and) layers, each of them grips, used for clamping leathers; On the path of the carriages, machines for cleaning the hides of SALT, scales for weighing the hides and racks for their laying are installed. Each grip consists of a yoke attached to the carriage, carrying clips fixed on it, made in the form of a bracket, on one end of which a cam is fixed, which interacts when clamping the skins with one shoulder of a double-arm lever, which is pivotally mounted on the other end of the bracket; the other tsolo of this double arm is equipped with a finger.

On the traverse there are several other two shoulders, one shoulder of which, made in the form of a cam, interacts with the fingers of the two shoulders of the clamps, while the other shoulders are connected by a common thrust; one of the shoulders, connected with one another by a common thrust, is made elongated and interacts with an emphasis established in the path of movement of the carriages.

At the location of the weights, a second conveyor is mounted, moving with greater speed and equipped with fingers for removal

No. 134372- 2 carriages from the pushing stops of the traction chain and for feeding the carriages to the scales.

In a semi-automatic line, freight elevators are used to lift racks with skins to a level convenient for weighing and inclined w above racks, for proper laying of skins freed from grips.

 FIG. 1 shows a diagram of a semi-automatic line; in fig. 2 is a diagram of a carriage with gripping and stirring, Ayush: its their conveyor, a cross-sectional view; in fig. 3 - traverse scheme with clamps clamps; in fig. 4 - clamping scheme; in fig. 5 - the second conveyor; in fig. 6 - the scheme of laying skins with inclined shitov on the rack.

The semi-automatic line consists of the following main assemblies: chain suspension conveyor 1, pushing type with a machine 2 mounted on it to clean the hides from the salt, scales 3 to weigh the hides, racks 4 to lay the hides, small conveyor 5, freight elevators 6 to lift racks with skins, sloping shields 7 for proper placement of skins on racks. The freight carriages 8 mounted on the conveyor 1 move freely along the monorail 9 to a given address, automatically stopping at the unloading point. The carriages are made as clips and have three grooved rollers 10. Of these, the lower two roll along the monorail 9, and the third upper roller for stability of the carriage moves along the guide rail 11 located above it.

In order to transport the hides in a suspended and flattened state, the yoke 12 is attached to the carriage with the clamps as follows.

A bracket 13 is attached to the traverse, with a cam 14 and a double-arm lever 15 hinged at the ends, one arm of which interacts with the cam / 4, and the other (upper) arm has a hole in which a finger 16 is pressed. To ensure simultaneous opening of all the clamps of the beam 12 equipped with double-shouldered levers / 7, seated on axis 18. The upper arms of the levers / 7 are pivotally connected to a common thrust 19, and the middle arm of the two double-shouldered levers is extended and interacts with the carriage movement set on the shaft. The lower arms of the levers 17 are made in the form of cams having shaped grooves that interact with the finger 16, turning the two shoulders with the arm 20 to open the clamps, in order to release the skin and shed it, is carried out near the place of laying the skins by an automatic device of known design, the rod a resetter 21 of which, when pulled out, causes the lever to rotate with the arm 20, as a result of which the thrust rod 19 is mixed and the clips open, releasing the hides. The clamps are returned to their original position by an abutment set in the path of the carriage.

The conveyor 5, mounted on the scale location, consists of a chain 22, the links of which are attached to the fingers 23, sprockets 24, tensioning device 25, drive shaft 26 and frame 27. The drive shaft 26 receives rotation by means of a chain gear 28 (Fig. 1 ) from the drive pivoting device of the conveyor. One of the branches of the conveyor chain 22 with a length of 2 m is parallel and adjacent to the conveyor chain (Fig. 1). Using fingers 23 and a high speed of small movement of the conveyor, the carriages of the carriages 8 are withdrawn from the pushes of the drag chain of the suspension conveyor 1 and fed to the scales 3 for weighing the hides.

The inclined shields 7, represented by “a FIG. 6, are mounted pivotally under the monorail 9 against each place where the hides are placed on the racks 4 and are designed to give them the necessary direction during the release of the hides from the grips, ensuring that the rack is properly laid on the rack. A screw 29 is hinged to it to change the angle of the shield. The angle of the shield varies from 40 to 50 ° depending on the weight of the skins.

A rack with hides by an electric forklift is fed to the lift truck platform 6.

The claws are filled in succession with the paw, the rump and the second paw of the skin so that it moves with the conveyor in the stretched and flattened state. The skin thus suspended at several points in a straightened form is conveyed into the machine 2 by means of a conveyor to remove salt, where the salt deposited on it during canning is applied with soft twigs of the rotating shaft. From the machine 2, the shchkura moves to the weighing area, where the conveyor 5 fingers 23 automatically captures the cargo carriage 8 with the skin pulls it away from the ball: a low pushing end of the conveyor chain and installs it on the weighing monorail 3 (Fig. 1). The rollers 10 (Fig. 2) of the freight carriage fall into the well and the carriage with the skin stops. By weighing the handle, the weigher opens the scale 3 and the skin is weighed.

After weighing and closing the scales, the articulated pushing end of the conveyor drag chain pushes the cargo carriage off the monorail 9 (Fig. 2) and transports the hide to the sorting area. Sorting hides produced two workers, each on the site of its lift. To inspect the skins over their entire height, workers have the option of pushing the trigger buttons to raise or lower on the lifts.

After sorting, the skin is guided to the picking area in a state bent across the edge, where it is automatically dropped and laid down (against the bend) through the inclined shield 7 (Fig. 6) onto the rack 4.
