SU57571A1 - Machine for viewing raw materials and other materials for scrap - Google Patents

Description

The invention relates to machines for viewing scrap of raw leather and other materials in the form of a drum with transparent walls and internal light sources with a tick-borne device for grabbing hides for the duration of the drum movement.

In the proposed machine, in order to enable continuous consecutive examination of the skins on both sides, the drum is connected to a drive that communicates a return movement to it.

In order to remove salt and dirt from the go-to skin, the machine is equipped with a spring-loaded adjustable grooved bar, between which and the roller interacting with it is laid the skin.

In FIG. 1 shows a front view of a machine for viewing raw materials and other materials for scrap; FIG. 2 is a side view; FIG. 3 - its top view; FIG. 4 is a bottom view of the grooved bar; FIG. 5 is a side view.

On two racks / with bearings 2 a drum 3 is installed, consisting of metal discs and

glass side cylindrical surface. Inside the drum there are several rows of light bulbs 4 with reflectors. At the rear of the machine, on brackets 5, there is a freely rotating wooden roller 6, to which the slide bar 7 is pressed during the working stroke, on the concave surface of which the knives 8 are mounted at an angle. Each bracket has a finger with a roller 10 that rolls along the drum disk 11 drive curve. The other end of each bracket 9 is all the time under the action of the spring 12, pressing the strap 7 to the roller 6. The clamping mechanism for the skins consists of a grooved strap 13 fixedly mounted and the strap 14 fixed pivotally on the drum discs 15, the second end of which is attached to the drum.

To loosen the bars / 3 and 14 serves as an emphasis 16. The machine is driven from the electric motor 17 by

double gear 18 and chain transmission 20.

To change the direction of rotation of the drum are two friction clutches 21.

The machine is started by pressing the pedal 22 mounted on the shaft 23, on which also sits the clamp 24, which translates the switch-on cone 25 and the track-hold sector 26.

The tail end of the skin - the middle part upwards is laid on the roller 6 and the bar 13, after which the pedal 22 is pressed. and wound it on the glass surface of the drum. When the clamping bar rotates 350 ° and the second end of the skin falls from the drum to the floor, the drum automatically reverses and, turning the skin on the other side, moves to the starting point, where it automatically stops, simultaneously raising the drawbar 7 and the presser 14.

During the slow movement of the drum, the sorter has the opportunity to inspect the skins on both sides while scanning through it. When the drum is stopped, the de-skinned skin is removed and transferred to the scale, and the next is laid in the machine.

The subject matter of the invention.

Claims (2)

1. A machine for viewing raw materials and other materials for rejection, equipped with a drum with transparent walls and light sources located inside it and with a ticker device for grabbing hides for the duration of the drum movement, characterized in that the drum is connected to a drive that tells it back - rotational movement for continuous, consistent inspection of the skin on both sides. 2. In the machine according to claim 1, the use of a spring-loaded adjustable grooved bar 7, which interacts with the roller 6 and is designed to remove salt and dirt from going to the skin. "about.
