Description

one

The invention relates to loading devices for supplying blanks to a machine and can be used, for example, for loading aggregate machines.

A device that feeds the blanks from the loading position into the working area of the machine, made in the form of a movable and fixed base prismatic jaws. In the base prismatic sponge, a floating gland sponge 1 is additionally installed.

The disadvantage of such a device is the relative complexity and low rigidity of the structure. ,

The aim of the invention is to simplify the design of the boot device and increase its reliability in operation.

This is achieved by the fact that the proposed device is provided with wedge clamps that mate with the side walls of a tray having corresponding wedge surfaces, and the feed carriage is installed with the possibility of rotation about its axis and the fastening fingers attached to the wedge clamps are installed on it.

FIG. 1 schematically shows the proposed device, a longitudinal section; FIG. 2 is the same, view along arrow A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows an arrow B in FIG. one; in fig. 5 is a view along arrow G in FIG. 1. The proposed device comprises a bottom 1 of the feed carriage, a cheek 2 rigidly fastened with a petal 3. A blank is placed in the carriage 4. The bottom 1 is rigidly fastened with a rail 5 which is rigidly connected to the sliding

a plate 6 located in the guide plate 7, the pusher 8 is located in the drive sleeve 9 with the drive bristle 10 rigidly connected to it 10. On the sleeve 9 there is fixed the drive pin 11 enclosed in the helical groove of the control sleeve 12, on which there is a control pin 13. The latter is located in the helical groove of the body control of the sleeve 14 fixed on the base 15. The device also contains limit switches 16, 17

and 18, the stop 19 mounted on the mechanical part of the machine 20 containing the clamping mechanism 21, tightening fingers 22 (Fig. 2, 3), interchangeable pads 23, - clamps 24, tray cover 25, tray bottom 26, bracket 27 ( 2), guide pins 28, carriage end 29 constituting 30 trays, base 31 of the tray. The boot device operates as follows. Pre-oriented blanks 4 are continuously fed along the bottom 26 of the collecting feed tray (FIG. 2). The tray installation angle a must ensure the natural sliding of the bale along the arrow a. Since the assembly feed carriage consisting of the bottom 1, cheek 2, petal 3, and the initial position of the device is an extension of the tray, it will be constantly loaded with workpiece 4. The stop 19 attached to the mechanical part of the machine 20 acts on the limit switch 18 (Fig. 2): The stop acts in the direction of arrow b (Fig. I, 2). The switch 18 is connected to an electro-hydraulic-hydraulic system, which drives the drive sleeve 9 to the left according to the arrow in. By means of a driving pin 11 rigidly mounted on the sleeve 9, placed in the helical groove of the control sleeve 12, the sleeve 9 is turned clockwise. Cutting the groove (-left) and the angle in the helix lift ensure self-unraveling By means of the gear wheel 10 rigidly fastened with the sleeve 9, the rail 5, rigidly fastened with the bottom 1 to the rail 5, is set in motion, the feeding carriage is also retracted (arrow d) to the left. Wherein . The rail 5 slides in the guide plates 7 and adjusts the other sleeve 12 until it is disconnected: After disconnection, the feed carriage is turned counterclockwise (arrow d) to a position in which the feed axis of the workpiece 4 in the tray becomes vertical. With the start of the movement of the feeding carriage, the tightening fingers 22 and the interchangeable pads 23 rigidly fastened with the bottom 1 compress the components 30 of the tray, stopping the next workpiece 4 from random sliding in the feeding tray. . When moving the feed carriage on the plate 7 at the same time pushing the gear 10 on the rail 5 to the left (arrow 6). The finger 11 rests on the limit switch 16 associated with the electro-hydraulic system Ioi, by means of which the control sleeve 12 is set in motion with the control finger fixed on it 13. Push the finger 13 in the screw-shaped groove of the body control sleeve 14 to the left ( arrow fl) at the same time turn it counterclockwise (Fig. 2). The cutting of the groove (right) and the angle of the helix lift are provided for unscrewing. Thus, the workpiece 4, placed in the feeding carriage, is separated from the total flow of workpieces in the feeding tray, and the workpiece 4 with the feeding carriage is turned and pre-fed into the area of the clamping mechanism 21 of the machine 20. The control pin 13 abuts against the limit switch 17 associated with the electro-pneumatic hydraulic system, by means of which the pusher-8 moves to the left (arrow 6). The pusher 8 advances the workpiece 4 to the centering section .1-1, where it is centered by means of a spring lobe and fed into the clamping mechanism 21 of the machine 20 until it stops. By means of an electro-pneumatic device, such as a pressure switch, the device is returned to the pump. Petal 3 has an inclined surface in section I-I, which ensures a clear fixation and subsequent correct direction of the workpiece 4 into the clamping mechanism 21 when exposed to the pusher 8, and also prevents the workpiece 4 from accidentally falling out of the centering section when the pusher 8 is in the initial position. Section II-IP prevents accidental jamming of workpieces at their arbitrary sliding into the sub-1-first carriage. Claims of the invention The loading device is mainly for body blanks with a tray consisting of a bottom, a lid and side walls and a feed carriage mounted for movement along the axis of the tray, characterized in that, in order to gain grip and reliability, the structure is simplified with wedge clamps mating with the side walls of the tray having corresponding wedge surfaces, and the feed carriage is installed with the possibility of rotation about its axis and the tightening fingers are mounted on it, hooks Wedge clamps.
