(54) DEVICE FOR TRANSPORTATION OF PRODUCTS

I

The invention relates to continuous transport machines, in particular to chain conveyors, and can be used in the wire industry to feed wire coils in a vertical position to the bracing machines.

A device for transporting articles is known, which includes a bunker and a vertical conveyor, made in the form of two: parallel traction chains with plate carriers, tensioning and drive sprockets (1).

. However, the device does not provide for the transportation of wire bundles in an upright position, which is necessary to automate the binding process on the binding machine.

It is also known a device for transporting articles, including a horizontal conveyor, a bunker and a vertical conveyor mounted on the uprights of the frame in front of the receiving tray, with drive and driven shafts connected by a supporting beam and having sprockets around infinitely closed chains with load grippers 2).

A disadvantage of the known device is the lack of reliability of operation due to the possible jamming of the coils of the wire in the bunker, which leads to disruption of the normal operation of the device when it is captured by the vertical conveyor.

The purpose of the invention is to improve the reliability of the device when a vertical conveyor bays the wire from the bunker.

This goal is achieved by the fact that the vertical conveyor is installed on the frame by means of a drive shaft fixed in bearings with the possibility of swinging motion.

In addition, the vertical conveyor has a balancing device.

The balancing device is made in the form of weights connected by means of cables and guide rollers to the carrier beam.

FIG. 1 shows the device, a general view; in fig. 2 - the same plan view; in fig. 3 - vertical conveyor and receiving tray; in fig. 4 is a view A of FIG. 3i in FIG. 5 is a diagram of the operation of the vertical conveyor; in fig. 6 - Seeked B-B on

FIG. one; in fig. 7 is a diagram of the installation of a vertical conveyor in an inclined position.

The device consists of a horizontal conveyor 1 and a vertical conveyor 2 mounted on a common frame 3. Each conveyor has an individual drive 4 and 5. Between the conveyors there is a bunker 6.

The horizontal conveyor includes leading 7 and driven 8 shafts with asterisks 9, mounted on sub-supports 10. Asterisks are covered by infinitely closed roller chains 11 with thrust supports fixed on them 12 serving as separating links of the load-carrying body to keep the coils in an inclined position ( 10-15 °) and the ability to load the conveyor on the go. The chains are a tail and load-carrying organ and rest on the longitudinal bars 13. The thrust pillars 12 are pivotally connected to the chains 11 and self-aligning in a fixed position on the upper branches of the chains at the transition from the lower ones.

A vertical conveyor (FIGS. 3 and 4) is mounted on the frame 14 in front of the receiving chute 15, on the racks of which a drive shaft 17 with sprockets 18 is mounted on bearings 16. A support beam 20 terminating at the bottom of the sprockets on bearings 19 to which is attached a knotted sprocket assembly consisting of a yoke 21 with threaded rods 22 serving to adjust the tension of the chains. Shaft 24 with bearings 23 pockets with cantilevered sprockets 25, covered with closed chains 26, supported on bars, carrying hinge-mounted carriages 28 on the connecting rollers 27, are mounted in bearings. Carriages are made in the form of platforms connected to chains in the front and tail parts, moreover, in the tail part of the roller 27 passes through a longitudinal groove 29, which serves to ensure the transition of the carriages through sprockets. In the central part of the carriage there is a longitudinal shaped protrusion (horn) to grip the coil from the hopper 6 and transfer to the receiving tray 15 (Fig. 1 and 3).

The collection tray consists of a box with a sloped bottom (10-15 °) towards the side of the dressing belt. The inner sidewall of the box at a height from the bottom equal to 1 / 2-3 / 4 of the diameter of the bay is inclined towards the sprockets at an angle of 30-45 ° and has slots for free passage of the carriages. The tray is equipped with automation elements: a spring-loaded plate with a shank interacting with a limit switch, controlling the starting and stopping of the section is pivotally fixed on the bottom. An electromagnet is mounted on the outer side, which controls the limiter 30, which holds the coil in the tray. The vertical conveyor is made in the form of a tambourine, balanced by movable loads 31, on cables 32, thrown over the rollers 33, which are a balancing device (Fig. 1). The frame has adjustable stops limiting deviations of the movable unit.

sections.

The bunker 6 (Fig. 1) is attached to the frame 3 under the ANGLE of 30-45 ° and is equipped with automation elements similar to the receiving tray 15, controlling the starting and stopping of the load-carrying body 1. The bunker has shaped cutouts for the passage of the uprights 12 and the carriages 28.

The device works as follows.

In the initial position horizontal

the conveyor 1 is loaded with coils 34, the carriage 28 of the vertical conveyor 2 is below the hopper 6 (Fig. 5), and the stopper 30 of the receiving tray 15 is fixed in the vertical position — the tray is closed. A horizontal conveyor is turned on from the control panel. The bay 34 slides into the bunker 6 and switches off the load-carrying body through the automation element. The upper part of the bay, located in the bunker, overlaps the lower part of the bay, located on the load-carrying

organ, preventing its arbitrary slipping. A vertical coivier is included. The carriage 28 moves upwards and picks up the coil from the silo. From position to position from the bay, it describes an arc around a certain point w, the deviation of the lifting member from the vertical position. In the deflection angle position, "t is the maximum. The magnitude of the thrust forces depends on the masses of the lifting body and the balancing weights 31. In the area from position to position with a bay on the load carrying body it is kept from an arbitrary fall into the bunker. From the position from the bay goes to the vertical position and describes the arc from the point m. With respect to the arc, the plane of the bunker is

the tangent, therefore, between the lower point of the bay, located on the carriage, and the plane of the bunker, free space is formed (Fig. 5). In the event of a spontaneous fall into the bunker of the next bay, it will not touch the previous bay located

on the carriage. .

When exiting the bunker, the bay through the automation element turns on the load-carrying body — the next bay is fed.

In the upper position “d (fig. 5) bay

It begins to descend from the carriage 28 to the receiving tray 15. For an uninterrupted descent, it is necessary that the length of the protrusion “/ s on the carriage be less than the internal diameter D of the bay.

In the receiving chute, through the automation element, the coil disconnects the load-lifting section and is held by the limiter 30.

Upon a command from the control panel to the "feed", the electromagnet of the limiter is triggered, and the coil rolls into the binding machine, simultaneously turning on the lifting device. From this moment the device enters the automatic mode of operation. The supply of the coils to the drying machine, is only activated by a command from the control panel.

H3o6peTjeHHe allows you to reduce time losses and load the load carrying body, load on the go, thereby improving the performance of the automated baying line, as well as increased reliability and operating conditions.
