Description

The invention relates to the field of mechanical engineering and can be used for the automatic unloading of automated lines, metal-cutting and assembly machines.

According to the main author. St. No. 944869 is known a loading device containing a carriage equipped with a puller and installed with the possibility of reciprocating movement along the vertical p, and inclined trays of the magazine, track automation elements, a spring-loaded stop ruler and a lever probe, hinged on the puller with the possibility of one end interacting with parts on inclined trays, and the other with a resistant ruler when lifting the carriage.

This device is intended for the unloading of blanks from the store and their transfer to the transport device of the serviced machine (machine, line, etc.), and the magazine is of the gravity type, i.e. with inclined trays 1.

A disadvantage of the known device is that it cannot be used for reverse cargo operation - loading parts from the vehicle transport device into the store.

The aim of the invention is to expand the technological capabilities of the boot device.

This goal is achieved by the fact that the loading device containing a carriage equipped with a puller and installed, with the possibility of reciprocating movement along the vertical row of trays of the magazine and elements of track automation, is equipped with a component loader from the carriage puller to the magazine, made in the form of hinged on, the rack slats installed with the ability to move along the trays of the store, and an additional spring-loaded lever mounted at the end of the lever probe, interacting with and a puller carriage configured to nest parts and slots for the passage and is mounted horizontally reloader and lower probe-arm at a distance between the trays schaga store.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; FIG. 3 shows the moment of controlling the filling of the magazine; in fig. 4 - option of loading case-type parts to the store with horizontal trays.

The loading device consists of a magazine 1 for parts. 2, carriages 3 with a puller 4 and a two-arm lever probe 5, a ruler 6 with stops 7 and cams 8 and 9 interacting with the throttle 10 and the sensor 11, the reloading part with the bars 12 and the mechanism controlling the filling of the magazine with the sensor 13.

Store 1 is a frame with inclined (or horizontal) tray 14 with rigid stops 15. To increase capacity, it can be made multi-fold. FIG. 2 depicts stores with two vertical rows of trays. The carriage 3 has the ability to reciprocate along the vertical row of the trays of the magazine along the guides of the rack 16 with the help of a plunger hydraulic cylinder 17.

The puller 4 is rigidly fixed on the carriage and has a slot that provides fixation

parts 2. In the puller there are grooves for the possibility of movement along the row of trays of the slats 12 of the part reloading device. The manipulator 18 is designed to load parts on the puller.

made in the form of two levers, freely mounted on the axis 19 and having a kinematic closure with each other through the spring 20 and the protrusions on the levers. An additional lever 22 is fastened to the end of the lever probe 5. On the axis 21, a torsion spring (not shown) is pressed to the stop 23. The sensor control lever lobe 24 is also fixed on the axis 21. In the lower (initial) position of the carriage 3 the lever is probe 5 spring 25 is installed on the carriage stop (the position shown in Fig. 1

dash-dotted lines).

The ruler 6 is installed in the directions fixed on the rack 16, and the spring 26 is set to its initial position against the stop in the bottom of the lower guide. Top

the position of the ruler is limited by the adjustable stop 27. The stops 7 on the ruler 6 are made according to the number and in steps equal to the number and vertical step of the trays 14 of the magazine 1. The cam 8 presses when lifting the ruler until it stops on the roller of the lever of the hydraulic cylinder 17 braking 17 and the cam 9 includes in the upper position of the ruler sensor 11.

Reloader parts 2 with puller 4 carriage in the store 1 consists of slats

The magazine filling control device consists of a sensor (contactless switch) 13 (Fig. 3) mounted on a rack 16 and a petal 24 mounted on an axis 21. The petal 24 turns on the sensor 13 after the vertical filling is complete

P Yes Trays Store 1 item 2.

The magazine 1 is mounted on the trolley 31, which can move across the magazine trays along the rails 32 (Fig. 1) from the drive 33. The cart has two places for installing two magazines at once 1. Parts are loaded into one store, another store can be replaced, i.e. the filled magazine is removed and installed empty. For such work, the stores are made in the form of removable cassettes with elements for fixing them in the required position on the trolley 31. A support 34 is fixed on the rack 16. The trays 14 of the store have limiting bars 35 on top.

The device works as follows.

Before the parts are loaded into the magazine, the carriage 3 is in the lower position, the slats 12 of the reloader are driven to the left by the drive 29 (in Fig. 1 they are shown by dash-dotted lines). The manipulator 18 feeds the loaded part to the puller 4 of the carriage 3, after which the carriage by the hydraulic cylinder 17 moves upward along the guides of the rack 16 until the lever 22 stops in the upright 34 when loading the upper tray of the magazine, or into the last part of the first, from the bottom of the filled tray, as shown in figure 1. In this case, the lever probe 5 rotates on the axis 19 (the npykHHa 25 is extended) and with the other arm engages with the stop 7 of the ruler 6. The latter, together with the carriage 3, moves to the adjustable stop 27, and its cam 8, interacting with the throttle 10, performs smoothly braking the hydraulic cylinders 17. Since the end of the horizontal arm of the lever-probe 5 is located on the stop 34 (or rests on the part of the filled tray 14), and the axis 19 continues to move with the carriage and the ruler 6 to the stop 27, the protrusions of the shoulders of the lever-probe 5 with stretch m springs 20, that allows to have a stroke of the carriage, necessary for braking and soft stop on the stop 27. At the end of the movement range of the cam 6 9srabatyvaet sensor 11, commands the actuation reloader parts. At this point, the puller 4 of the carriage 3 is aligned (or slightly higher) vertically with the tray of the magazine 1. From the drive 29 through tgu 30 and the articulated parallelogram of the suspension 28, the slider 12 of the reloader moves from the left (shown in FIG. 1) to the right, push up part 2 from the puller 4 carriages on the tray

14 stores. Then the carriage 3 under the action of its own weight, and the thrust ruler 6 and under the action of the spring 26 is lowered down to its original position. Team on

The switching of the hydraulic cylinder for the downward movement (connection of its cavity with the drain) can be supplied from the track automation elements (not shown) that are triggered at the end of the stroke of the reloader plates, which are then also retracted to the original (left)

FIG. 1) position. In the initial position of the carriage 3, the manipulator 18 reloads the part onto its puller 4, and the cycle of loading the part into the magazine repeats until the tray 14 is completely filled, after which, during the next run of the carriage 3 with the part up, the lever 22 abuts the last part of the filled tray and fills downstream magazine tray To avoid dropping parts of light weight when the lever is pressed into them 22 the magazine trays have

0 restrictive slats 35.

When lowering the carriage 3 down after filling any of the trays of the magazine 1, the lever 22, interacting with the last part of the just-filled tray, rotates around axis 21, ensuring unhindered lowering of the carriage. Moreover, if the last (lower) tray 14 of the magazine is filled, the tab 24, turning on the axis 21 together with the lever 22, enters the slit of the sensor 13, which causes it to trigger and issue a command to fill the row of magazine 1 (Fig. 3) and moving the cart 31 from the drive 33 to the pitch. Opposite the puller of the carriage 3, an empty magazine row is installed, and the magazine loading cycle is repeated. Loading of parts into the empty magazine always starts from the top tray and ends with filling the bottom one. After the store is fully loaded, the cart moves to a position where an empty row of another is placed opposite the carriage puller.

 store. The filled magazine is replaced by an operator using workshop lifting equipment.

The proposed loading device can also be used to load parts into a store with horizontal trays, as well as body (non-ramming) type parts, which also expands its technological capabilities.
