Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for manufacturing elongated products such as rods, tubes, profiles, etc., having a product feeding section, a cutting saw that operates transversely thereto, and a length cutting stop that is adjustable in the forward direction. It relates to a stacking device that cuts lengths and transports them to a stacking section by a product transport device.

Generally, elongated products come in long lengths and are then separated for further processing and stacked in layers in transport or annealing racks or frames, commonly formed as sideboard pallets.

If the products are stacked closely together, the transport frame can be used effectively. In particular, the internal width of the frame must be utilized as fully as possible.

Generally, a cutting saw is used to cut the length of a product manufactured to a process length, and a length cutting device is used to cut the length with the cutting saw to the desired process length.

The products cut to process length are then typically manually stacked in layers in a transport frame. This creates a significant burden on workers in today's production volumes and often becomes a production net. On the other hand, manual stacking often cannot be avoided for various reasons.

It is an object of the present invention to provide an apparatus for cutting and stacking lengths of elongated products, which can optionally be used for mechanical or manual stacking in transport frames such as sideboard pallets. It is also an object of the invention to provide a device which allows switching from mechanical to manual operation or vice versa without requiring structural changes.

According to the invention, this object is achieved in a device of the type mentioned at the outset, in which the conveying device comprises a plurality of rollers forming a roller carpet supporting the products moving above, the rollers being wound in parallel. At the same time, the chain itself does not move when the product is conveyed, and only the rollers can be rotated to convey the product. This can be accomplished by means of a cutting-to-length and stacking device, characterized in that the roller carpet is removed from the conveying path by movement of a chain driven by sprocket wheel means. In a first embodiment of the invention, the stacking device is arranged following the feed section and immediately adjacent to the cutting. This arrangement has the advantage that this operator stands close to the stacking unit and can monitor the mechanical stacking operation and intervene if necessary in case of trouble. Furthermore, this arrangement requires only a small amount of space, is inexpensive and easy to work with. In this case, length-cutting sections can also be combined with stacking sections.

In another embodiment of the invention, a length cutting section is provided in line with the feed section between the stacking section and the cutting. The length-cutting section has a product transport device, a length-cutting stop is adjustable along the length-cutting section;
This length-cutting section can be adjusted for laterally discharging the products for manual stacking, and the stacking section transport device is driven.

In a second embodiment having the above-mentioned characteristics, the length-cutting section and the stacking section are arranged in line, the length-cutting stop is formed as a gate structure, and the gate structure is hinged to the top of the gate and It has a stop plate that can be pivoted upwardly to allow cut products to pass through the stacking section.

In a third embodiment, a longitudinal conveyor, which is used specifically for raising and lowering and is laterally adjustable, is arranged next to the length-cutting section, and a stacking section is arranged in line with the longitudinal conveyor.
The horizontal conveyor conveys the cut product from the length cutting section to the vertical conveyor.

In a fourth embodiment, the stacking section is arranged next to the length-cutting section, and the cut products are conveyed directly from the length-cutting section to the stacking section by means of a cross-feed conveyor, thus providing an additional longitudinal section. The feed conveyor is omitted.

Although these embodiments require more space and have more complex structures than the first embodiment, they concentrate the products at a high density in the center in an arrangement that cannot be easily implemented in the first embodiment. be able to.
If these embodiments are used for manual stacking, this involves moving the products laterally from the length cutting section and layering them onto the transport frame (second and third embodiments). Should I put it on?
Alternatively, it can be carried out very easily either by feeding the product across the stacking section and then placing the product by hand (fourth embodiment).

If desired, the length cutting stop in the third and fourth embodiments can be formed as a gate structure for the product path with a stop plate as described above. If the cross-feeding conveyor is also arranged in the first embodiment together with the stacking section, this device must be moved upwardly to ensure that the conveying frame remains accessible from the side for mechanical stacking operations. It must be able to swing. Additionally, the side stops must be removed to allow manual stacking, which is not required in other embodiments for manual stacking.

The conveyor of the fourth embodiment has a conveyor arm which is advantageously used for moving transversely to the longitudinal direction of the products and for raising and lowering with respect to the level of the supply section and the stacking section. It is advantageous if the conveyor arm is synchronously driven by a rack pinion drive and is supported elastically in the lifting direction by a flexible stop.

All embodiments of the invention provide that the conveying device of the stacking section is formed by rollers supported on both sides by chains, which chain together with the rollers can be moved out of the stacking device by means of a guide device and a guide sprocket wheel. It is characterized by being designed. In this way the so-called "roller carpet" is created for stacking.
The rollers forming the product are simply pulled out from under the elongated product, whereby the product or finished product is lowered onto a lifting support arranged below.
This allows a very careful and fully automatic stacking of the products into the transport frame. Lateral stops, at least one of which is adjustable, are provided for laterally defining the product. It is particularly economical to drive the rollers of the stacking device by means of friction belts. In order to convey the product into the stacking device and to stop it when these rollers are moved away from under the product, one friction belt is pressed against all rollers and It is sufficient to drive it.

A common sideboard pallet can be used as the transport frame. These transport frames must have openings at the bottom to allow the supports used for raising and lowering to pass through to the stacking position.

The pallets can be moved on the carriage at right angles to the direction of advance, so that an empty pallet is always already ready when the previous pallet is in a stacking position on the underside of the roller carpet.

, if the rollers of the stacking device extend transversely to the direction of advance, diagonal rollers are provided on the length-cutting section arranged in the form of vanes at an angle with respect to the direction of advance and are at least partially driven. ing.

These diagonal rollers are advantageously driven by a belt drive comprising pulleys angularly offset with respect to each other via a common axis extending in the forward direction.

The present invention will be explained in detail below based on some embodiments shown in the drawings.

In the apparatus for length cutting and stacking shown in FIG. 1, a feed section 1 is followed by a cutting saw 2, which is followed in the forward direction by a length cutting section 3, which cuts the length 3. A length-cutting stop 4 is adjustable along the length-cutting stop 4 and is followed by a stacking section 5.

The feed section 1 of the elongate product 6 as well as the length-cutting section 3 are equipped with driven diagonal rollers 7, which are arranged at an angle with respect to the advance direction A and in the form of a feather.
This arrangement causes the elongated products 6 to be concentrated in the pile width b toward the center of the conveyance path.

When the product fed in the forward direction A is moved against the length cutting stopper 4 which is adjusted to the desired production length l, the product is cut along the dash-dotted line 8 by the cutting saw 2.

The length cutting stop 4 is designed in the form of a gate consisting of a bridge carrier 9 and a pedestal 10 on both sides. A stop plate 12 is rotatably mounted on the bridge carrier 9 at a location 11 (see FIG. 3). This stop plate 12 is pivoted upwards about a hinge point 11 in order to allow the cut products to pass into the stacking section 5 under the conveying action of the diagonal rollers 7 in the length cutting section 3. Ru. In the stacking section 5 the products are fed by rollers 13, in which the rollers 13 are arranged at right angles to the direction of advance A, and the products pass between lateral stops 14, 15, at least one of which is laterally adjustable. do.
In the stacking section 5, rollers 13 transport the products as will be explained in more detail with reference to FIGS. 6 and 7 below. In this way, the product 6 is lowered onto a support as will be described in more detail below.
This support stacks the products in layers or stacks within the transport frame 16. Figure 1 shows a transport frame fully loaded with products 6 on the lower side;
An empty transport frame 16 is shown at the top. The transport frame can be moved in the direction of arrow B in FIG.

The products are automatically stacked in the stacking section 5, while manual stacking onto the transport frame 16 can take place in the length cutting section 3. To facilitate this operation, a cross-feeding conveyor 18 is provided which facilitates the removal of the elongated product from the conveying path and conveys it in the direction of arrow C towards the conveying frame 16.

In the embodiment shown in FIG. 2, the cutting saw 2 is immediately followed by a stacking section 5 similar to that described with reference to FIG. Here, the length cutting stop 4 is integrally integrated into the stacking section 5, the position of which can be adjusted by moving the spindle drive 4' along this stacking section 5. In other words, there is no length-cutting section 3 with driven diagonal rollers; in this case the length-cutting section is combined with the stacking section 5.

After the length cutting of the products that have been moved towards the length cutting stop 4, stacking takes place automatically in the stacking section 5, similar to the embodiment shown in FIG. However, if manual stacking is required, the lateral stops 15 must be removed in order to be able to remove the elongated products 6 in the direction of arrow B.

In this case, the length cutting stopper 4 does not need to have a gate structure as shown in FIG. In other words, the stop plate 12 that swings upward is unnecessary. Instead, a stop device with a fixed stop plate is provided.

FIG. 4 shows the drive of the oblique roller 9 in the length cutting section according to FIG.

The belt pulley 20 is arranged to rotate concentrically with and together with each diagonal roller 7.
Each belt pulley 20 is provided near the center of the length cutting section 3 at the inner end of the diagonal roller. Each belt pulley 20 is associated with a large diameter belt pulley 21 mounted on a shaft 22 extending in the forward direction A. belt pulley 20,
21 are arranged one above the other in such a way that belts (not shown in FIG. 4) are placed over the belt pulleys 20 and 21 for driving the belt pulleys 20 and the diagonal rollers 7. Since the axes of the belt pulleys 20 and 21 intersect, the belt must follow a twisted path. In this way a common drive of all oblique rollers from the central shaft 22 is easily ensured.

5 to 7 show in detail the stacking device located in the stacking section 5, which will be described in detail below.

The rollers 1 of the stacking section 5 are rotatably supported in ball bearings 30 at both ends. This ball bearing 30 is provided on a joint plate 32, which forms part of a chain side bar of two chains 34 that are movable laterally in the forward direction A. The chain 34 has rollers 36 between its chain side bars, by means of which the chain 34 runs on the lower leg 38 of the U-shaped guide 40. As shown in FIG. 5, these guides 40 are curved upwardly and rearwardly at the ends of the stacking section 5, following the outer diameter of the sprocket wheel 42, shown in dashed lines. These guides 40 also have a length at the rear such that both chains 34 are conveyed over their entire length to the upper section under the action of the sprocket wheels 42, so that the rollers 13
is moved away from under the product path indicated by dash-dotted line 44 in FIG.

In the conveyance state, each roller 13, 13... is driven by a belt drive device or the like so that the roller itself rotates in the circumferential direction without moving in the conveyance direction, and the product A passes on this rotating roller.
It is designed to be driven in the direction. This drive belt 50 is shown in FIGS. 5-7. . The upper path of the drive belt running around the synchronously driven rollers 51, 52 moves in a direction opposite to the forward direction A. Drive belt 5 together with side stopper 14
0 can be adjusted laterally in the direction of arrow S and vertically in the direction of arrow h, while the other lateral stop 15 can only be adjusted laterally in the direction of arrow t. chain 34
When the product is conveyed to the upper section, i.e. when the "roller carpet" consisting of chain 34 and rollers 13 is withdrawn from under the product, drive belt 50 is stopped, thereby causing roller 13 to move in contact with the product. The circumferential speed applied to is made zero. The product thus remains in place without the need for braking or holding devices.

An elongated recess 54 is provided on the underside of the stacking section 5. This recess 54 accommodates an elongated beam 56, which consists of two bars of U-shaped cross section arranged back to back. This elongated beam supports a support 58 which has a transverse carrier 60 at its upper end. The cross carrier 60 is designed in such a way that it passes through an opening 16' formed in the bottom of the transport frame or pallet 16. The transverse beam 56 runs around sprocket wheels 61, 63.
It is suspended by book chains 62,64. These chains 62, 63 are mounted at locations 6 on piston rods 66 of hydraulic cylinders 67, which are arranged horizontally beside sprocket wheels 61, 63.
It is installed as shown in 5.

In this way the support 58 and the lateral carrier 60
is raised and lowered within the recess 54 by actuating the hydraulic cylinder 67;
It passes through the opening 16' of the pallet 16, which is placed in a stacked position above the recess 54 as shown in FIGS. 6 and 5.

FIG. 6 shows not only the sideboard pallet 16 in the stacking position, but also another empty pallet in a waiting position on the left side of the stacking section. Both of these pallets are placed on trolley 70.
The carriage 70 can be moved by means of wheels 72 on rails extending perpendicularly to the forward direction A. The support 58 on the bottom of the trolley 70 is raised and lowered.
An opening 70' is formed to allow passage of the transverse carrier 60 at the free end of.

FIG. 6 shows the situation in which the transverse carrier 60 already supports two product stacks 6. When the "roller carpet" is moved away from the underside of the next stacked layer 6' in FIG. 6, this stacked layer 6' is lowered onto the top layer 6 of the product stack.
Operation of hydraulic cylinder 67 then lowers beam 56 by the height of one stacked layer. This is repeated until all pallets are placed in the stacking position or are fully loaded. When the truck 70 is moved to the right, the empty pallet 16 shown on the left side of FIG. 6 is moved to the stacking position. The stacking process then begins again.

All the steps described with reference to FIGS. 5 and 7 can be controlled fully automatically to save labor and allow for rapid stacking. However, in the same way, the stacking operation can also be carried out manually, as already mentioned with reference to FIGS. 1 and 2, if this is required for special reasons.

In the embodiment shown in FIG. 8, the same parts as those in FIG. In this case the stacking section 5 is laterally offset with respect to the length-cutting section 3 and is aligned with the longitudinal conveyor 80.
This longitudinal conveyor 80, designed as a roller bed and arranged next to the length-cutting section 3, is used for lifting and lowering the transverse conveyor belt 1.
8 is provided with an opening to allow it to pass through.

Vertical conveyor 80 used for raising and lowering
The roller bed of can be adjusted laterally so that the stacked pile of stacked products can be separated exactly as desired from the wide pile of cut products.

In this way, the embodiment shown in FIG. 8 allows the predetermined width of the stack to be adjusted during automatic operation, regardless of the width of the pile of cut products.

Furthermore, the apparatus shown in FIG. 8 allows for easy selection of unusable materials after product division and before stacking.

Manual operation without automatic stacking is also possible by lowering the vertical conveyor 80 and removing the products from the horizontal conveyor 18.

9 and 10 show another embodiment. In these drawings, parts that are the same as those in FIG.

As in the embodiment shown in FIG. 1, the length cutting section 3 is arranged in line with the feed section and next to the cutting saw 2. The length cutting stop 4 is movable along the length cutting section 3. However, unlike in FIG. 1, this length cutting stop 4 is not aligned with the product path, although it is provided as required.

Stacking section 5 is cut to length section 3
extends beside and parallel to it. This stacking section 5 is designed in the same way as described with respect to FIGS. 5 and 6. The difference is that the transport frame 16 in this case cannot be moved laterally of the stacking section 5 in the direction of arrow B as in FIG. 1, but can be moved longitudinally of the stacking section 5. However, the transport frame 16 can also be moved laterally. Carriage 70 with rollers 72 has been replaced by a car (not shown) for transporting transport frame 16. This carriage can be moved in the longitudinal direction of the stacking section and perpendicularly to this direction as indicated by the arrow.

A cross conveyor 18 is arranged between the length cutting section 3 and the stacking section 5.
This traverse conveyor 18 has an arm 118,
These arms 118 are movable by a rack and pinion drive (or sprocket wheel and pin drive) having a pinion 120 and rack 121. A pinion 120 and a rack 121 are fixed to each arm 118 for movement laterally synchronously in the direction of arrow B with respect to the two sections 3, 5, thereby adjusting the width of both sections 3, 5 as well as the width of both sections 3, 5. It can be moved over the entire width, including the spacing between sections. A pinion 120 connected to each arm 118 is provided on a through shaft 122 . The crank arm 119 has a through shaft 12 that is in line with the rotation axis for the vertical movement of the arm 118.
This through-shaft 122 is supported for rotational movement around the axis of No. 4. The through shaft 122 and pinion 120 are rotated together by a shaft 124 operating via a belt or chain drive 123. The crank arms 119 support at their free ends guide members 125 for the forward movement of the conveyor arm 118. These conveyor arms 118 are raised and lowered by a separate compressed air drive 126, which at the same time constitutes a resilient stop. These are the length cutting stopper 4 and the arm 118.
This is necessary to prevent a collision between one of the The elastic stops 126 individually follow up if the length cutting stop 4 becomes obstructed.
If the length cutting stop 4 collides with one arm 118, this arm 118 will lag behind the other arm. A common shaft 124 is placed at the axis of rotation for the lifting and lowering movements to prevent difficulties in this relationship.

FIG. 10 shows arm 118 in its fully extended position, with it swung downwardly by an angle ε. When swung into its upper position, arm 118 projects above the surface of the section 3,5 roller bed by a dimension a.

If manual stacking is desired, the products are conveyed by a transverse conveyor past the stacking section 5, from which they are drawn and lowered onto a conveying frame 16'' arranged beside it. be done.

The apparatus shown in FIG. 9 can also be used to stack several short stacked layers one after the other.
For this purpose, manual positioning is carried out by means of movable slides (not shown) in the stacking section 5, and the stacking layer consisting of several part-length products is lowered in one step onto the remaining stacking layer. .

FIG. 11 shows an embodiment similar to FIG. 9, in which the pile of cut product and the pile of stacked product are different, as is sometimes required in practice. They differ in that they can be stacked even if they have a wide width. The width of the pile of cut products is designated by s in FIGS. 11 and 12, while the width of the stacked product is designated by b.

Length cutting section 3 and stacking section 5
The transverse conveyor 130 disposed between the sections is a belt conveyor 130 disposed beside these sections.
have. The belt conveyor 130 has at least a cut pile width s and a stacked pile width b.
has a conveyance length equal to the sum of . The lateral feed conveyor can rotate around a rotation axis 131, which coincides with the axis of the right drive roller 132 as shown in FIG. 12, and its rotational movement is performed in the direction of arrow C. It will be done. In this way the pile of cut products is lifted outside the length cutting section 3 and the drive roller 132 is then operated to move the pile of cut products in the cross-feeding direction D. When the pile of cut products reaches the top of the belt conveyor 130 at the location marked s on the right in FIG.
All conveyor belts are stopped. A lifting conveyor, generally designated 135, is located between the belt conveyors 130. The structure of this lifting conveyor is particularly shown in FIGS. 11, 12 and 13. As can be seen in the figures, each lifting conveyor 135 has a crank lifting arm 134.

This lifting arm 134 has a support surface whose length corresponds to the pile width b. Lifting arm 134 can be moved in lifting rail 137 by means of rollers 136 in the direction of double arrow D, that is to say in particular in the transverse conveying direction as shown in FIG. The lifting rail 137 is a parallel link 13
It is used for raising and lowering by means of a drive (not shown) operating via 8. The movement of the lifting arm 134 that can be achieved in this way is indicated by the rectangular arrow X. During this movement, the lifting arm 134 moves the stacked product upwardly from the pile of cut products to form the maximum pile width b. The lifting arm 134 then moves over its rollers 136 in the direction of arrow D to the right in FIG. 12, where it lowers the lifted pile of pile width b onto the stacking section 5. This stacking section basically has the same structure as described with reference to FIGS. 5 through 7, so a description thereof will be omitted. If necessary, the stacked pile can be made narrower than the maximum pile width b as follows. For this purpose, an adjustable stop 139 is provided, which reduces the pile width b, for example to the position indicated by the break in FIG.
can be adjusted together in the direction of

In operation as described above, products of width s-b always remain on the belt conveyor 130. During each working step, another residual product is added to the next pile of cut products, so that this residual product continues to increase until it constitutes a total stack of width b.

The apparatus described with reference to FIGS. 11 to 13 is suitable if the stacked pile width b is the cut pile width s.
It can also be used if it is larger.

The apparatus described with reference to FIGS. 11 to 13 may be used in combination with the embodiment according to FIG. 9, but not with the embodiment shown in FIGS. 1 and 2.

The device according to the invention can be used not only for stacking operations but also for non-stacking operations. For this purpose, the stacking device described with particular reference to FIGS. 5 to 7 must be operated in such a way that a sufficiently stacked pile is introduced into the stacking section. For this purpose, the accessories shown schematically in FIG. 14 are required. Lifting hooks are provided to lift the top layer off the pile as shown in FIG. This hook has a horizontal hook part 140 which lifts the top layer 141 of the stacked product so that the rollers 13 move between the top layer 141 and the next layer 142.
You can get in between.
