Description

The invention relates to a device for the metered pouring of liquid from a barrel, which has at least one handle accessible from above.

In the chemical industry, mainly medium-sized barrels, so-called barrel or balloon barrels with a capacity of 60 und and also smaller containers, so-called canisters with a capacity of up to 30 sind, are known for the transport of acids, alkalis or other working liquids, each of them rectangular, with rounded edges are designed so that they can be combined to form a transport container in a space-saving manner by means of a foil strip or a collecting trough designed for 6 containers, for example.

These containers differ from each other in addition to their capacity mainly by the number of handles arranged on the top of the barrel, on which they can be gripped and lifted either by hand or a hoist hook. Common to all containers is an upper pouring opening and a recessed grip molded into the container bottom on the side opposite the pouring opening. Conventional balloon barrels can be divided into two main types, one of which has an upper horizontal central handle and the other two upper horizontal handles near the opposite circumferential sides.

Such barrels are poured into galvanic immersion baths, for example, in order to compensate for liquid losses or concentration deviations in a solution. Since only small amounts of substance are often required for such refills, the relatively small containers are particularly suitable for this purpose, even if they are too heavy when filled to be able to be handled manually with sufficient certainty.

It is therefore customary to hang the container onto a crane hook with one of its handles, to pull it up and to move it over the basin to be refilled. Since a suspended barrel cannot be tipped over by hand, it is usually placed on the edge of the pool and then tipped over by lowering the crane hook. This creates the risk that the barrel slides off the edge of the pool and causes damage to the device or injuries to the operator if dangerous content escapes in an uncontrolled manner. Above all, the barrel contents cannot be emptied in a metered manner, since the hoist cannot be adjusted with sufficient sensitivity. In addition, when refilling from the edge of the pool, the concentration of an immersion bath is only greatly changed in the edge area, which requires a longer homogenization of the bath content by stirring.

Although the problems described above can be avoided if the drum contents are conveyed into the plunge pool by means of a pump for emptying the doses, residual quantities remain in expensive pumps suitable for this purpose, which can react with the substances of subsequent pumping processes. Since the often very aggressive residual amounts leak and pose a danger to the environment, the pump and its suction and Conveying lines require complex cleaning measures after each use.

From US 5 425 614 a lifting and emptying device for balloon-like water bottles with a large capacity is known in order to refill permanently installed tanks of public drinking water dispensers. The device consists of a mobile frame with a deflection roller mounted on an upper boom, over which a winch-operated rope for pulling up a hanger suspended thereon runs. On the ring beads of the water bottle to be emptied, a cuff is attached, which carries two diametrically arranged pivot pins, with which the water bottle enclosed by the cuff is rotatably suspended in the hooks of the bracket. Then the water bottle can be pulled up by means of a winch and moved with the frame over a tank to be refilled, so that after the water bottle has been pivoted through 180 °, its neck-like mouth protrudes into the receiving opening of the tank.

From US 2 937 836 a mobile frame for handling bulbous barrels is known, on which a barrel holding frame is pivotally mounted about a horizontal axis. The holding frame, which has a diametrical trunnion, consists of a support ring which encompasses the bulbous barrel near its lower end face, a semicircularly curved support part lying laterally against the largest circumference of the foot, and a rod running parallel to the barrel axis with an adjustable clamping device in order to reach over the upper barrel edge , so that the now clamped barrel with the holding frame can be tilted or pivoted about its axis of rotation.

The object of the invention is to provide a device for the metered pouring of liquid from at least one upper handle containers, in particular balloon drums of the aforementioned type, which is characterized by simple, inexpensive construction and user-friendly easy handling and with which a standing barrel quickly and safely detected , raised and transported to the point of consumption and emptied in doses.

According to the invention, this object is achieved by a device having the features of claim 1.
In order to empty a barrel over a plunge pool or bath, the device is placed over the barrel laterally, the adjustable frames being aligned with one another. After the barrel has been grasped by simple gripping of the holding device on its handle or handles, the device with the barrel secured therein can be raised and transported to the point of use, whereupon the tilting frame with barrel and the supporting frame parts is pivoted relative to the supporting frame, until the liquid flows out, the device being able to be moved over the basin or another collecting container during the pouring with the aid of a lifting device or a lifting truck.

The device according to the invention is further developed in that the holding device has at least one horizontal bolt rotatably mounted on the tilting frame above the associated gripping handle, to which the at least one gripping hook is fastened such that its opening in a plane perpendicular to the bolt between a Release and one engaging position engaging the barrel handle is pivotable.

Preferably, both the pivot pivot bearing (s) and a stop extending into the swiveling path of the gripping hook are attached to an upper crossmember of the tilting frame as a resting rest for the gripping hook (s) pivoted into the release position.

A parallel retaining pin can be attached laterally to the bolt, which can be displaced with respect to its pivot bearing due to axial play, which acts in the engaged position of the gripping hook by longitudinal displacement as an anti-rotation lock coming into engagement with the cross member. Furthermore, a safety stop can be arranged on the pivot bearing at a point in the pivoting path of the holding pin activated by unintentional longitudinal displacement, at which the gripping hook is located near its release position.

According to another embodiment, the holding device can have at least one vertical bolt mounted above the associated gripping handle on an upper cross member of the tilting frame. To secure drums with two upper side handles, this holding device can be provided with two vertical bolts, which are mounted in the area of the crossbeam ends and extended by gripping hooks, to which a spring-loaded lever system is connected for joint rotation adjustment, which is operated by means of a hand lever between the release and engagement Positions of the gripping hook defining stops can be actuated.

In a further development of the invention, a simplified transporting and handling of the drum emptying device proposes a transport trolley which can be moved on rollers and on whose holding frame the device provided with a drum is suspended at such a height, optionally by means of a winch is brought to such a height that the barrel can be emptied with a variable tendency to tip over.

1, a dimensionally stable support frame 10, similar to an inverted U, has two parallel vertical frame legs 14 which are stiffened against one another at the top by means of a crossbar 16 and are connected above them by a curved bracket 17, for example, which has an eyelet 12 for attachment to a hoist. Carries the hook. A normally vertical tilting frame 20 is rotatably mounted on the lower ends of the frame legs 14 and, like an inverted U, also has two parallel legs 21. The bearing connection between the outer support frame and the inner tilt frame consists of two axially aligned, one tilt axis 18 forming bolts that hold the adjacent frame legs together in an articulated manner.

The lower ends of the tilting frame legs 21, which are extended over the tilting axis 18, are connected to one another by a first bracket 22, the shape of which is adapted either to the entire or half the circumference of a barrel (cf. FIGS. 1 and 6). Approximately midway between their ends, the legs 21 are connected to one another by a second bracket 24, which is only adapted to half a barrel circumference. Both mutually parallel brackets 22 and 24 are stiffened against each other by a vertical connecting web 26. The upper ends of the legs 21 are connected by a cross member 28 to which holding devices 30 and 32 for different gripping handles and a ventilation device 88 are attached. One of the two legs 21 is extended upwards by an extension 36, to which a laterally projecting handle 38 is fastened for manual actuation of the tilting movement.

If the supporting frame 10 and the tilting frame 20 are aligned with one another as in FIG. 1, the device is slipped over the side or from above over a standing barrel. This transport state of the device is ensured in that a latch bolt 40 which can be pivoted on the support frame 10 engages over the extension 36 on the tilting frame.

In order to pivot the tilt frame 20 relative to the suspended support frame 10 in accordance with FIG. 2, the latch bolt 40 is opened and the desired tilt angle is set on the handle 38. The maximum tilt angle> 90 ° is due to on the tilt frame legs 21 below the tilt axis 18 fixed stops 42 limited, which lie on the support frame.

According to FIGS. 1, 3, first holding devices 30 for barrels with two side handles each have a vertical bolt 44, which is mounted in the region of the ends of the cross member 28 and is covered on its upper side by a sleeve 48 and, for example, spinned with the latter. The bolts 44 each continue downward into a bent gripping hook 46.

For the purpose of jointly actuating the gripping hooks 46, the sleeves 48 are connected to one another via a lever system 50. A handle 52 starts from a main lever 56 which is pivotably mounted on a vertical pin 54 arranged centrally with respect to the crossmember 28 and is connected at its ends via links 58 to levers 60 fixed to the sleeves 48. Fig. 3 shows the lever system 50 in the state in which the gripping hooks 46 are in the release position defined by the fact that a link 58 or the main lever 56 rests against a stop 68 fixed to the cross member 28, against which the lever system 50 by a between a shoulder 66 of the handle 52 and the stop 68 extending spring 64 is biased.

In order to bring the gripping hooks 46 into engagement position, the main lever 56 is pivoted counterclockwise by means of a handle, the spring 64 moving over the dead center formed by the pin 54. The lever system 50 is now biased into the engagement position in which the lever 60, which is firmly connected to the right bolt 44 (FIG. 3), bears against a stop 62. This state is shown in FIG. 3, where the holding devices 30 secure a barrel 70 which, in the vicinity of the circumference, carries two handles 72 which are gripped by a gripping hook 46.

According to FIGS. 1 to 5, an additional holding device 32 is provided for securing balloon barrels with only one middle handle, which in FIG. 6 is part of a e.g. simplified device variant is shown for 30ℓ canisters. This holding device 32 comprises a bolt 74 which is extended by a handle 78 and carries a hook 76 on either side of the cross member 28. The horizontal bolt 74 is received in a pivot bearing 75 fastened centrally on the cross member 28. Starting from the release position, in which the hooks 76, which are open at the top, rest on a stop 80, they pivot downward when the bolt 74 is actuated in order to engage under the middle handle 82.

In order to secure the hooks 76 in the engaged position, a parallel displaceable holding pin 86 is attached to the side of the bolt 74, which is pushed forward to block the rotatability of the bolt 74 and thereby rests on the upper side of the cross member 28. Instead of a displaceable retaining pin 86, the bolt 74 itself can have sufficient longitudinal play with respect to its pivot bearing sleeve 75, so that the retaining pin 86 comes into locking engagement with the cross member 28 by displacing the bolt 74 including the gripping hooks securing the gripping handles.

In order to empty a barrel secured in the suspended device by the holding device, the tilting frame 20 is pivoted on the handle 38 after opening the latch bolt 40. As soon as the tilting frame tilts, the barrel 84 rests on the brackets 22 and 24. Since the tilt axis 18, preferably close, is above the center of gravity formed by the tilt frame 20 and barrel 84, when the handle 38 is released, the tilt frame 20 and barrel 84 in the support frame 10 automatically straighten up again.

In order to improve the metered drum emptying, a ventilation device 88 is attached to a suitable point of the cross member 28 and consists of a holder 90 and a pipe 92 bent at right angles. After securing the barrel in the tilting frame 20, the one pipe leg 94 is inserted into the barrel so that it points under the top thereof in the direction opposite to the opening 96. The vertical pipe leg 98 is clamped above the barrel opening 96 in a spring clip 100 of the holder 90. A shoulder 102 projecting laterally from the pipe leg 98 limits the distance of the horizontal pipe leg 94 from the barrel cover wall when resting on the edge or connecting piece of the opening 96 and prevents the pipe 92 from falling through the barrel opening when the spring clamp 100 is released. The adjustable holder 90 can be pivoted, moved along its elongated slot 104 and fixed at a suitable point on the cross member 28 by means of a button screw. The ventilation 88 ensures a constant pressure equalization in the barrel during the pouring process.

5, the gripping hooks 76 of the unused middle holding device 32 rest on a stop 80, while the gripping hooks 46 of the holding device 30 secure the two lateral gripping handles. Since the frame legs of the support frame 10 and tilting frame 20 have a low material thickness, the device need only be slightly wider than the widest barrel to be handled. Consequently, the device can be placed over each individual barrel of a crowded barrel group and fixed on it, since all handles and actuating elements are accessible from above and are not covered or obstructed by the neighboring barrels.

The drum emptying device can be used by means of a transport carriage 110 shown in FIGS. 8 to 11, regardless of whether a crane or a hoist is available.

The chassis of the transport carriage 110 consists of a rectangular base frame 112 which is open on one side, for example of a tube which is bent twice by 90 ° and is supported on four rollers 114. The rollers arranged at the open end of the base frame 112 can be fastened to the base frame with their axle bearing supports, while the two rear rollers 114 can be steered about vertical axes and are provided with a locking device. The distance between the side parts of the base frame 112 is sufficient to drive the trolley over a collecting trough 120 which is standing on the floor and is customary for balloon barrels.

On the base frame 112, two upright legs 126 of a holding frame 124 are fastened by means of connecting pieces 128 corresponding to FIG. 8. The upper ends of the legs 126 are connected by a crosspiece 130, to which an approximately U-shaped receptacle 132 is fastened in the height in the case of the windless variant shown broken off, so that the support frame 10, which is suspended from its bracket 17, including the barrel secured in the tilting frame 20, is free are located above a collecting pan 120 carried on the base frame 112 as in FIG. 10. The device is lifted by means of a crane or stacker and inserted into the receptacle 132.

The holding frame 124 is preferably inclined with respect to the vertical so far in the direction pointing away from the open side of the base frame 112 and the receptacle 132 jumps so far into that of the inclination of the holding frame on account of a connecting piece 134 connecting it to the transverse web 130 opposite direction that the center of gravity of the suspended device is approximately above a connecting line between the base points of the legs 126.

Horizontal strips 116 are provided above the side parts of the base frame 112 as a support for the outwardly curved edges 122 of the collecting trough 120 to be carried. According to FIG. 8, the strips are welded onto the frame sides via integrally inclined support parts 118.

In order to handle a device for metered drum emptying that has already been combined with a drum in a more versatile manner, the transport carriage 110 has a winch which has a winch frame 138 fastened to the crossbar 130 for mounting a winch shaft 136. The winch shaft 136 is connected via a backstop, possibly via a gear, to a hand crank 140 which can be folded over or removed when the trolley is being moved. With the aid of a cable pull 142 fastened on the winch shaft 136, a slide 144 guided on the legs 126 of the holding frame with rollers is adjusted in height. In the case of the shown lightweight construction of the transport carriage, the carriage 144 consists of two sheet metal strips that start at an angle from the two carriage guides 146 and are welded to one another via a round iron, which form a support projecting in the direction opposite to the inclination of the holding frame for fastening the receptacle 132. When the carriage 144 reaches its end position defined by a stop 148, the receptacle 132 is in approximately the same positional relationship to the holding frame 124 as in the winchless transport trolley shown.

The practical use of the trolley 110 is described in connection with a balloon barrel 70 with two side handles 72 as shown in FIG. 7, on which a device according to the invention is placed from a barrel side so that the cross member 28 of the tilting frame 20 rests on the top of the barrel and the Tilting frame attached horizontal bracket 23, 24 rest on the same half barrel circumference. The device can be set up by means of a crane or stacker or manually.

Of the three holding devices 32 guided on the cross member 28 in rotary bearings 75, the two outer ones are actuated to secure the side handles 72, for which purpose the bolts 74 carrying two gripping hooks 76 are rotated on their handles 78 until the gripping hooks have reached the engagement position shown . In this rotational position, the bolts 74 are shifted using their axial play in the pivot bearings 75 - to the left in FIG. 7 - so that the retaining pin 86, which runs parallel to the bolt, passes over the cross member 28 and thus acts as a back-up safety device.

The middle holding device 32 shown in FIG. 7 remains in its release position, in which it is locked by the ventilation device 88 which, when the middle holding device 32 is used, as shown in FIG. 6, is further fastened laterally to the cross member 28. In order to prevent a barrel with a central handle and use of the three identical holding devices 32 having the device according to FIG. 7, to prevent the two outer holding devices, whose gripping hooks 76 each rest on a stop 80 in the release position, due to the axial play of their bolts 74 in the tilted position of the barrel unintentionally rotate and their free gripping hooks interfere with the barrel, is a fixed safety stop 87 on the pivot bearing 75 at such a point in the swivel path of the by unintentional longitudinal displacement up to the pivot pin retaining pin 86 provided that the gripping hooks 76 can not leave their release position. In other words, the bolts and gripping hooks which are not in use, ie in the release position, are prevented from rotating due to the safety stop 87 when they are longitudinally displaced by the barrel being tilted.

7, the winch lift truck is moved up to where the support frame bracket 17 is gripped by the receptacle 132 of the carriage and the device is raised with the help of the winch to the stop 148 . According to FIG. 10, the barrel has reached a height at which the collecting trough 120 can be placed on the strips 116 of the base frame 112 and inserted up to a rear stop 150. When the trolley reaches a point of use, the drum can be emptied into a container which is in the collecting tray 120 available on the trolley. To tilt the barrel, the tilting frame 20 is freed from the supporting frame 10 by loosening the latch bolt 40 and the barrel is inclined by means of the handle for metered pouring.
