Method and device for filling containers

The invention relates to a method and a device for filling containers and is particularly directed to a device for Insertion of bales of soft, resilient material into containers directed.

During the manufacture of rubber and similar materials, particulate matter is formed under pressure into rectangular prismatic shapes called "balls". Usually these bales have an elongated configuration with a pair of wide rectangular side surfaces and a pair of narrow rectangular side surfaces. A typical rubber bales measures about JQ cm (28 inches) in length, 35 C (14 inches) in width and 17.5 ^cm (7 inches) in height and weighs about 33 kg (75 pounds).

Because of the air, which is under pressure during training; . the bale is trapped, a go ~ occurs in the ropes know relaxation, which causes the air bubbles to expand, stretch the rubber and cause the pads to swell. This effect is known as "pad swelling". It occurs a few minutes after the agglomeration and. leads to larger maximum dimensions of length, width and height, while at the same time a certain deformation of the original. rectangular prism shape occurs.

If these pads are flat for a week or more When they are stored on the surface, they change their shape Pages move under the through the top ™ portion of the bale superimposed outward pressure, u.nrl the bale possesses then the properties of a viscous liquid, indeia he flows into a larger surface in contact with the substrate, whereof a reduction in strength results and a deformation 3oi its original form. This is commonly known as "cold flow".

Under certain circumstances, these bales can be wrapped in foils or wrappers, which require transport to be cost-effective however, that they are in larger containers, firsts or ice creams be packed for handling with forklifts. It's beneficial j if this can happen immediately after the formation of the lobes, so that cold flow effects on a Kinimura can be restricted.

Furthermore, it is desirable that the Bales are stored on a wide rectangular surface for transport. This arrangement is also from a cold flow standpoint preferable, which solidifies the bales and makes pulling away the bales difficult. To pull away the

In λ ore erf indungsgemäßeii Bshälterlader sine Bejiäiter tiltable bearing means is provided which is designed so as to the 3rd-container-s holding the container on its side with the open Ilünduiig in a vertical plane in the zero position. A conveyor device is provided to arrange the bales lying on their usually rectangular surfaces in front of the opened mouth of the container, and a pressure device is also provided to push the bales from the conveyor into the container. Furthermore, means are vague for tilting the filled container into the upright position so that the bales are stacked on their broad rectangular sides when the container is in the upright position.

The container may have a number of separate cells or chimneys designed to individually withstand the hydraulic bridge of cold flow, and they may be arranged in a box or crate. Alternatively, the container may be without chambers and may be designed to be able to withstand the hydraulic pressure caused by the cold flow or may be enclosed for this purpose by a crate Preferably the container is provided with a number of vertical compartments so that when it is loaded while lying on its side, a number of horizontal compartments are available to receive the bales, and the container holder is vertically adjustable so that each ^{compartment can be aligned with the di 1} UCk facility to load the bales.

The bales are conveniently transferred from the conveyor to the container promoted on a ball carrier guide, preferably in the form of a metal plate with low side walls. These The carrier guide is preferably horizontal into and out of the container opening that receives the bale movable out. According to one embodiment, this extends End of tour while loading a series of bales only a little way into the container and is after Loading the row moved out of engagement with the container, to allow the container to move vertically. It then moves back into engagement with the bin to load the next row of bales.

According to a further embodiment, the guide extends in its fully extended position to the bottom of the Container. With this arrangement, a full row of bales are pushed into the container one at a time while they are still stay on the lead and when the entire row is brought in

is, it is vrird- by the pressure device in its position held and the guide withdrawn from engagement with the introduced bales and the container. When withdrawn Guide, the container can be moved vertically to the next loading position, and the guide will turn up introduced to the bottom of the container, and the process is repeated then. This arrangement is particularly advantageous when the container is not de-oiling internal compartments.

According to a further embodiment of the invention, the pressure device for pressing the bales into the containers has a raised perimeter. So it turned out that the use,. The use of a flat pressure device caused such deformations in the bale that the entry area was increased and that the bale weight tended to adhere to the leading edges of the bale. This is a typical phenomenon that occurs with materials that are easily stretchable, such as rubber. By placing a pressure plate with a raised perimeter on the surface in contact with the bale, the force at the perimeter is applied to the bale, with the result that the center of the surface of the bale tilts against the pressure plate. This causes the front surface of the bale to contract so that the front edges are raised and the -m

Bales with most or all of your weight moved on the trailing edges. This prevents the bale from sticking or jumping on the bale guide.

The bale pressure device can also be provided with an opening for Spraying a powdered powder such as talcum onto the bales. This helps to avoid that the bales stick to the pressure plate and also improves the sliding of the bale aif the bale guide or the Container department. The opening can expediently in one

A simplified illustration of the main components of the egg is given in FIGS. 1-4. _{It can be seen from} these figures that a container 1 is on a pallet 2 in the in 4 is brought onto a container holding and tilting mechanism 3. The mechanism is then tilted by 90 ° so that ^ assumes the position shown in FIG.

The illustration shows a three-chamber container and a scissors lift mechanism 4, which the container 1 in raises its upper position. A ball guide 5 extends in and lies on the edge of the bottom chamber of the container. In this position the container is for receiving Bales ready.

The bales 6 to be loaded are for example aufgenoruiiien from a roller conveyor by clicking on rest on a wide rectangular surface and are transported upwards via the inclined conveyor 7. If this The feeder is actuated, the bale 6 moves upwards and over the upper end of the conveyor, tilts in the direction of the arrow and falls onto the transfer conveyor 8, namely on a narrow rectangular surface (position 6a), with its longitudinal axis lying in the direction of movement.

The transfer conveyor can be in the form of a belt or a chain conveyor or a pair of banks of short rollers may be used with a transmission rail extending lengthways in a passageway between the banks the roles are moving. The transfer conveyor 8 is preferably designed so that the bales sequentially along it are moved and that they are attached to a ball guide 5 in front of a Printing plate 9 are passed.

As can be seen from FIG. 3, the one with the bale 6 Contacting surface of the pressure plate 9 is preferably provided with a raised peripheral edge 10. This allows that the bale can tilt towards the center of the pressure plate, as shown, with the front surface 11 of the bale 6 contracts. As explained above, "this prevents sticking or jumping of the bale on the bale guide 5 · The pressure plate 9 comprises preferably also an opening 12 for spraying dust powder onto the bale. This opening is with a flexible hose

_ 13 connected, which with a source of the dust powder below ™ pressure is connected.

During operation, the conveyor holds 7 £ Φ ·> after the bale 6 has migrated up the conveyor 7 and tipped into position 6a, and the conveyor 8 is actuated, which brings the bale one position forwards (position 6b). This leaves the position 6a unoccupied, and the conveyor 7 is operated again, bringing another bale into position 6a, so that now bales are in positions 6a and 6b. The conveyor is operated again, with the bale in position 6b brings into the bale guide 5 and brings the bale from position -6a to position 6b, so that on this Veise the £ position under the conveyor 7 remains empty. In this stadium the conveyor 7 is actuated again, wherein it fills the position 6a. Now the printing device .9 is actuated, which the The bale on the guide 5 is pressed a short distance into the container and pulled back around the area in front of the printing device (see Fig. 2) for the entry of the to release the next bale. Now move "all bales one position further so that the next bale in the Bale guide 5 enters and he gets with the first bale pressed a bit in front of him. This process will last as long xfrepeated until a specified number of bales in the loading

holder has entered. The entry of the last bale in the row signals a long stroke, and the row of The bale is in contact with the pressure device Pressed the bottom of the container. The printing device 9 remains in this position and the guide 5 is withdrawn, after which the printing device 9 is also withdrawn. This signals the downward movement of the container into the second chamber, by means of the scissor lift device 4, so that it assumes the position shown in FIG. In this position, the entire process described above is repeated until the second chamber is filled, whereupon the container goes down again and the third chamber is filled.

after all the chambers of the container are filled and the I ¹ UhX ¹ UiIg 5- and the pressure device 9 are withdrawn, the tilting mechanism J is actuated, tilts the container back into the vertical position, which is shown in Fig. 4- in which it can be closed, tied with a tape and removed, for example replaced by a forklift truck and another empty container. The entire process is then repeated with a new container.

This system can be easily carried, photoelectric cell, limit switch, clock, etc. to automate, so that when a leaer container is placed on the tilting mechanism 3, by the operator merely a button must be printed, to set the cycle in motion, and the entire cycle is automatic until the container is filled and returned to the upright position for removal. The system can also be completely automated by providing an automatic feed conveyor for empty containers and an automatic conveyor device for discharging the filled containers.
