Device for mounting tires on containers, in particular barrels

The invention relates to a machine for the production and maintenance of containers or barrels, which consist of several wooden panels held together by metal tires.

In the manufacture of barrels, the wooden staves are carefully processed so that they are after they have been put together result in a barrel shape. However, in order to keep the staves in their position and to achieve a leak-free one To press the barrel tightly together, the metal hoops must be inflated onto the tapered end portions of the barrel will. In addition, with used barrels it is often necessary to tighten the staves to a certain extent * by advancing the tires on the corresponding barrel sections.

So far, the metal hoops have been driven on barrels done by hand, which is time consuming and difficult.

The purpose of the invention is to create a machine that allows the production and maintenance of passports mechanical mounting of the tires accomplished.

This object is achieved according to the invention by a device with a base on which a frame is mounted that carries a press head that can be moved up and down to the base and by several push arms attached to each one end is articulated to the press head and can be moved with it, and their free ends are connected to it attack a tire placed around a barrel placed on the base while propelling it.

The push arms are preferably arranged distributed around a circumference and each become the center of the circle held down.

Preferably, a plate is provided on the press head which engages with the arms and toward the base up and down and relative to the arms along this is movable to the distance between the free ends of these Change arms from the center of the circle.

The plate can be pressed against the end rim of a barrel in a driving manner.

The device for expanding barrel hoops also has means for lifting the barrel from the base and for supporting the keg so that it is reversible by rotation.

The invention is explained in more detail using an exemplary embodiment shown in the drawing. It demonstrate:

Fig. 1 is a diagrammatic front view of the device according to the invention for mounting barrel hoops, wherein the press head is raised and out of operation,

FIG. 2 shows a view of the device according to FIG. 1, but with the press head lowered and engaging a barrel grip Push arms,

3 is a fragmentary front view of the lifting device on a larger scale.

The device for mounting tires on a barrel or the like. Essentially consists of one on a not shown Rectangular base 1 placed on a concrete foundation, from the corners of which there are vertical square uprights 2 tower, the upper ends of which are connected by means of a platform 3 in the manner of a frame. Any stand carries a vertical guide rod 4 on each of which one corner of a press head 5 is slidably mounted., so that the head can be moved up and down to the base 1 within the frame.

Two double-acting hydraulic pistons 6 actuate the press head 5 · The cylinders 6A become the hydraulic pistons supported by the top of the platform 3 of the frame, while their piston rods 6b attack the press head 5. To ensure uniform operation the piston rods and the cylinder bores are hard chrome-plated.

The hydraulic pressure for actuating the piston-cylinder units is generated by a hydraulic pump 7, which from a fully encapsulated 15 HP 440 V electric motor is driven.

On the press head 5, the upper ends 8A of ten are upright distributed over a circumference at a distance Articulated thrust arms 8, which are each spring-loaded towards the center of the circle, so that the lower arm ends after be pressed inside. Each arm 8 carries at its lower end a gripper 9 'which consists of a barrel hoop Applicable blade part 10 made of hardened steel and an edge part located below the blade part 11 is formed over which the blade part 10 protrudes inward. Each gripper 9 is via a hinge point 12 connected to its push arm 8 and provided with an outwardly directed approach 1}, which is attached to its free end is movably connected to the lower end of a rod which is essentially parallel extends to the arm 8 and is screwed at its upper end into one end of a fork 15, the other end of which is connected to the press head 5 by means of a clevis pin 16. The position of the blade part 10 and the edge part 11 can therefore by removing the clevis pin 16, rotating the fork 15 and reattaching adjust the fork by means of the bolt 16. The position of the arms 8 is controlled by a hydraulic piston 17, which is mounted on the press head 5 and whose piston rod engages centrally on a circular plate 18 whose Circumferential surface of each of the arms 8 touches and their perpendicular movement the arms 8 to the center of the of them enclosed circle, i.e. swings back and forth to the vertical axis of the entire device.

Fig. 3 shows a machine provided on the frame Device for lifting and reversing a barrel 19 » which has two clamping tips 20, which are arranged opposite to the barrel and each on a parallelogram linkage 21 are grown, which can be actuated hydraulically in such a way that the barrel is clamped between the tips 20 and in this state is raised so far that

it is rotated about the bearing tips 20 in the reverse position can be ', whereupon it is reset back to the base i. Each paralleiogram linkage 21 is from a vertical guide bar 23 displaceable Console 22 worn. Each console 22 is from eleventh Hydraulic piston 24 on the guide rods 23 upwards or slidable downwards so that the height of the tips 20 is changed, which in turn is controlled by a hydraulic piston 25, which is attached to a link of the 'linkage 21 engaging lever 26 acts against the passport 19 or from. are movable this way.

All hydraulic pistons are operated by control valves, which are housed in a housing 27 located on one side of the frame, with valve control levers 28, 29, 3Ö * 31 are grouped so that they are one Operator are accessible at the same time.

According to Pig. 2, for example, a barrel tire 32 is attached to the passport 19 placed on the base 1; De ^r press head IB Lower this purpose by the KöibeÜ 6 and the arms 8 are by the piston 1? and dei? Plate 18 adjusted with respect to the fitting diameter, so that the edge parts 11 of the gripping organs 9 ^{slide down on the outer surface of the barrel staves 1} until the cooling parts 10 come to rest against the tire 32. The press head 5 is then lowered further down by the piston 6 until the tire 32 has been slipped over the upper tapering part of the passport and pressed into the desired position * while the drum 3 ^ · is preferably placed on the passport and pushed by the plate 18 itself into the desired position. Then the drum mounted on the tips 20 is lifted, rotated and the same process of tire removal.

subject to drawing.

With used barrels you can go to the gieichö tighten the tires. The one acting on the tires hydraulic pressure can vary between about 5 to 50 tons.

Before the tires mentioned were fitted, the FäM became better known Provide with a working tire.
