Description

The invention relates to a standing baler for bundling, for example, packaging material, cardboard, wood, sheet metal, etc., with a group consisting of a bottom and four would find ä pressing chamber, and a movable press table in the chamber. The press table is moved in the vertical direction with the aid of a drive device with spindles provided outside the press chamber and nuts interacting with these.

Balers of the type mentioned above are already known. According to a known construction, the press is in essentially comparable to a box that is open at the top. The main weakness of this type of press was that it did not have the strength required to withstand the pressing forces or the impact of the press table. Around to remedy this deficiency, one saw above the,

Press chamber before a movable upper part, which the vertically movable press table in the press chamber and the for the Movement of the press table required drive and guide devices fcaltert.

In presses of this type, the upper part can either be swiveled horizontally about a vertical swivel axis provided on the side of the press chamber, or it can be swiveled around. a horizontally arranged axis can be pivoted. In both cases , a significant part of the top of the pressing chamber is exposed for the purpose of supplying material to be pressed. The disadvantage associated with these arrangements is that the baler,

corresponding to the swiveling or folding out of the upper part space required over the footprint of the press, requiring a substantial dead floor space. In addition, this is Pivoting or flaps to open the press or to close it ■ again, laborious and time-consuming.

The drive device supported by the upper part has in the today presses used either a hydraulic working cylinder on, which cooperates with a piston attached to the press table, or racks, which with corresponding Pinions cooperate and in turn attached to the press table are. Both hydraulic working cylinders and racks extend vertically upwards from the top and are stressful towards the top, the · essentially the maximum Corresponds to the stroke of the press table. Which of these construction methods you also use, you have to accept the disadvantage, assume that only about half the height of the room can be used for moving the press table.

Other disadvantages with previous balers are that the Attaching twine or wire after the pressing process is completed is extremely cumbersome. In addition, the Do not check the bale size or, with certain material, the weight of the bales.

A main purpose of the present invention is to provide a baler which does the baling much larger Allows bales within a given volume. Another essential task is to make a baler in which the time required for filling and pressing can be significantly reduced. Next one becomes easy A manageable press aimed at, which can therefore also be operated by female staff. Furthermore, the attachment of Tying twine or wire is made easier and a controllable bale size or a controllable bale weight is possible be made.

Advantages of the invention listed above and others

Equipment.

According to the description above, the pressing chamber is 3 like a box to the side and to the top and bottom too limited. You get access to chamber 3 in that the Forehand 5 forms a door which is pivotably suspended on one side wall. Furthermore, one has one in the upper part the door 5 recessed, pivotable at its lower edge stored hatch 13 access to the chamber.

The opened hatch 13 is made predominantly more horizontal by an arrangement provided on the outside of the door 5 Held in position, as can be seen from FIG.

The rear wall of the pressing chamber 3 has a number of grooves 15 running vertically over the entire height of the wall, as can best be seen from FIGS. 2 and k. Through these grooves 15, firmly attached, hook-like noses l6 protrude on the rear edge of the press table k. Similar hooks 17 are provided next to the grooves 15 on the outside of the rear wall 6.

At the top of the bale chamber floor 2 15 U-irons 18 are provided corresponding to the number of grooves. These U-irons extend parallel to the side walls 7 ₅ 8, to one of the grooves 15 each. M den der ^; Door 5 facing end, the U-iron are pivotably mounted on the floor 2 and can be pivoted in a vertical plane, parallel to the side walls. A chain 19 is attached to the free end of each U-iron 18 on the rear wall 6. During the pressing process, the upper ends of the chains 19 are attached to the hooks 17> when the bales are tipped out, they are attached to the lugs 16 of the press table.

The vertically movable prose table k provided horizontally in the pressing chamber 3 consists of U-iron 20 or the like, which extend between the front and rear walls 5 ₅ 6. This U-iron 20 are through one on their top, about

held together at half the length of the beam. • In the vertical plane in which the U-iron 18 can be pivoted and in which the grooves 15 are located Gaps 21 are present between the U-iron 20. The width of the spaces is in the order of magnitude of 20 mm.

During its movement, the press table k maintains its horizontal position all the time. This is made possible by a special guide device that monitors the position of the press table. The guide device consists of a carriage 31 which is stably fastened to each end of the beam and which preferably has two rollers provided with guide edges. These carriages 31 run along the beam structures 9 and 10, which simultaneously serve as guide tracks. The carriages 31 running outside the side walls 7, 8 are firmly attached to the tree of the press table h with the aid of a projection 33 fixedly attached to each tree end. These projections 33 extend through openings provided in the side walls Sehlitze 22 shown in Fig. H, therethrough.

The drive device has a drive motor 23 fixedly attached to the upper part, as can be seen from FIG. 6. is. From the drive motor 23 the drive is transmitted via V-belt 2k to an intermediate shaft 25 and further via chains 26 to two spindles 27, which are rotatably mounted in two corresponding guides 9, 10 and protrude with their upper ends above the upper part. The spindles 27 each interact with a nut 28 provided with grooves for lugs 32. The lugs 32 are attached to the projections 33 of the tree ends which protrude through the side walls 7, 8.

The baler described above is operated from a control panel 30. This switchboard 30 has switches for Switching on the upward or downward movement of the press table, as well as to stop these movements. Furthermore are a voltage divider on the control panel, as well as some end position

2 09812/117 1

Switches, indicator lights, various types of relays, etc. are provided.

The baling press according to the invention works in the following way. After preparing the press before starting work with the press table k in its upper position, the hatch 13 is opened and folded down until it is stopped in the horizontal position ^{by the arrangement I 1 +.} A suitable amount of material to be pressed is now introduced into the pressing chamber 3 and the hatch 13 is then closed. The switch for the downward movement of the press table k is then actuated.

The press table k- now moves downwards and compresses the material located in the chamber k . As soon as the pressing pressure set with the voltage divider has been reached, the press table h automatically returns to its upper end position. This is followed by renewed filling and renewed pressing as before. As soon as the compressed bale has reached a height at which the press table reaches the sensor of the middle, height-adjustable limit switch under maximum pressure during its pressing movement, the feedback pulse from the voltage divider to the motor is blocked and the press table k remains in its lower position. At the same time, a signal lamp lights up on the control panel.

Now you open the door 5. When preparing the press before the pressing process, binding thread or wire is inserted into the U-iron 18, pulled further up along the rear wall 6, where it is hooked into place at the top. After opening the door, the upper end of the yarn or wire is detached from the rear wall and pulled out through the spaces 21 of the press table h under the beam of the press table and connected to the other end of the yarn or wire, which is caught at the front end of the U-iron 18 will.

The upper ends of the chains 19 are then released from the hooks 17 firmly attached to the rear wall and attached to the through the Rear wall protruding lugs 16 attached to the press table. Of the

2 0 9 812/1171

The switch for the upward movement of the press 1 is then operated. The table h now extends the upward movement
Chains 19 ₅ with the continued movement upwards have the consequence that the free ends of the U-irons 18 located on the rear wall are pivoted upwards and outwards and in this way eject the bale.
