Abstract
Description
Technical Field
[0001] This utility model relates to a placing device with a lifting frame for placing bar stock. Background Technology
[0002] It is well known that metal produces a lot of noise when it falls and hits the ground. Utility Model Content
[0003] Therefore, the purpose of this invention is to design a low-noise storage method for bar stock.
[0004] An important feature of this invention in the placement device is that the placement device is provided with a lifting frame for placing bars (especially round bars) in a receiving unit, especially a box, of the placement device. The lifting frame is capable, especially periodically and repeatedly, moving from a first lifting position, especially a vertical position, to a second lifting position, especially a vertical position, and especially back. A hollow roller is rotatably mounted in the lifting frame, and the rotation position of the roller can be controlled by a drive device, especially a stepping drive device, arranged in the lifting frame. The roller has an opening through which at least one bar, especially a round bar, can be received.
[0005] One advantage is that it reduces noise generated when receiving and lowering bars, especially metal bars. This is because lowering bars solely by gravity, while fast, also generates significant noise. According to this invention, low-noise operation can be achieved by controlling the descent of the bars.
[0006] In an advantageous embodiment, a ramp, particularly designed as a plate, is provided on the support frame of the placement device. Through this ramp, especially when the lifting frame is in the second lifting position, the bar can be conveyed to the lifting frame, specifically to the rollers. The advantage here is that the bar can be passively conveyed to the lowering area.
[0007] In one advantageous embodiment, the first lifting position is lower than the second lifting position. Advantageously, downward conveying from the higher position to the lower position can be achieved with low noise.
[0008] In an advantageous embodiment, in the second lifting position, the roller is located or can be located in a rotatable position that allows the bar material fed on the inclined plane to enter the roller through an opening and be received within it. Advantageously, a simple mechanism can be used here.
[0009] In one advantageous embodiment, the roller, or at least the receiving area for the bar formed within the roller, is made of plastic or textile fiber material. This has the advantage of further reducing noise.
[0010] In an advantageous embodiment, the first lifting position is located in the receiving unit, particularly at the bottom of the receiving unit, especially where the receiving unit is a box, particularly a grid box. The advantage here is that the corresponding rod can descend from the second lifting position to the first lifting position and from the first lifting position into the receiving unit with low noise.
[0011] In one advantageous embodiment, the lifting frame has a rod structure that, when the lifting frame is in a first position or in a lifting position between a first and a second lifting position, restricts, in particular, the bars, especially bars rolling down the inclined plane. The advantage here is that the bars are not blocked only when the filling rollers are in operation. Therefore, during the lifting motion, the bars are blocked and will not fall.
[0012] In one advantageous embodiment, the lifting frame has a rod structure, wherein the bar, especially the bar rolling down the inclined plane, is either directly or indirectly restricted, particularly blocked, by the rod structure, or received in the rollers, depending on the lifting position of the lifting frame. The advantage here is that the bar can only be conveyed to the rollers when the lifting frame is in the second lifting position. In the case of indirect restriction, a blocking mechanism is fixed to the support frame, which remains between the bar and the lifting frame until the lifting frame reaches the second position. At this point, the blocking mechanism is deactivated by the lifting frame. When leaving the second position or thereafter, the blocking mechanism will automatically activate.
[0013] In one advantageous embodiment, a linear drive device is mounted on the support frame, which enables the lifting frame to move relative to the support frame. The advantage of this is that the lifting frame can be moved in a controlled manner.
[0014] In one advantageous embodiment, the lifting frame extends beyond the inclined plane. This has the advantage that the lifting frame is arranged in a straddle-like manner on the support frame. Therefore, the support frame can be arranged on the side of the inclined plane opposite to the rollers.
[0015] In one advantageous embodiment, the placement device is erected on a flat surface, with the conveying direction, perpendicular to the roller's rotation axis, oriented parallel to the ground. The area covered by the vertical projection of the lifting frame onto the ground in the conveying direction includes the area covered by the vertical projection of the inclined plane onto the ground in the conveying direction. This has the advantage that the roller can move from the lifting frame to the internal space of the receiving unit, where the bar can roll out.
[0016] In one advantageous embodiment, the vertical projection of the receiving unit onto the ground includes the vertical projection of the roller onto the ground. This has the advantage that the roller can descend into the internal space region of the receiving unit.
[0017] In one advantageous embodiment, the vertical projection of the receiving unit onto the ground overlaps / interlocks with the vertical projection of the lifting frame onto the ground. This has the advantage that the lifting frame can be fixed to the support frame, and the rollers can descend into the receiving unit.
[0018] In one advantageous embodiment, a stepper drive device enables the roller's rotational position relative to the lifting frame to move from at least a first rotational position to a second rotational position. This has the advantage of enabling controlled operation.
[0019] In an advantageous embodiment, the stepper drive is designed to be passive, particularly with an elastic element. The advantage here is that no additional energy is required; instead, the rotational position of the rollers can be controlled using the gravitational potential energy released during descent. However, it is particularly necessary to activate the mechanical locking unit when the lifting frame descends to the first lifting position. This activation allows the rollers to rotate due to the weight of the bar, thus enabling the bar to roll downwards from the rollers. After rolling out, the elastic element must return the rollers to their previous rotational position and reactivate the mechanical locking device. This activation can be performed by the elastic element itself or by a second elastic element. This allows for purely passive / passive control of the rollers' rotational position.
[0020] In an advantageous alternative implementation, the stepper drive has a motor. The advantage here is that the rotational position of the rollers can be actively / actively controlled, thereby ensuring reliable operation.
[0021] This invention is not limited to the claimed combination of features. Those skilled in the art, based on the purpose of this invention and / or the task presented by comparison with the prior art, can derive other reasonable combinations. Attached Figure Description
[0022] The present invention will now be described in detail with reference to the schematic diagram:
[0023] exist Figure 1 The oblique view shows a placement device with a lifting frame 4 according to the present invention, used to assist the bar 2 (especially round bar) into the receiving unit 5 of the placement device, especially the box, wherein the lifting frame 4 is in a first lifting position.
[0024] exist Figure 2 Compared to Figure 1 The receiving unit 5 was hidden.
[0025] exist Figure 3 Compared to the middle lifting frame 4 Figure 1 It is located in the second lifting position.
[0026] exist Figure 4 Compared to Figure 3 The receiving unit 5 was hidden. Detailed Implementation
[0027] As shown in the figure, the placement device has a lifting frame 4 that can reciprocate in the lifting direction via a linear motor 1, and the lifting frame can move relative to the support frame 6.
[0028] An inclined surface 3 is provided on the support frame 6, and the conveyed bar 2, especially the round bar, is rolled down towards the lifting frame 4 by means of the inclined surface 3.
[0029] The hollow roller 20 is rotatably mounted in the lifting frame 4. With the aid of the linear motor 1, the lifting frame 4 can move from a first lifting position to a second lifting position and then back.
[0030] In the second lifting position, the roller is at approximately the same height as the bar 2 that has reached the lower end of the inclined plane 3.
[0031] The roller 20 has an opening extending in the axial direction, that is, parallel to the axis of rotation of the roller 20, through which the bar 2 rolls into the hollow interior space of the roller 20.
[0032] After the lifting frame 4 descends to the first lifting position, in the first lifting position, the lifting frame is located in the receiving unit 5, especially in the receiving area of the box. The roller is rotated by a circumferential angle value by the stepping drive device 21 or is allowed to rotate by that circumferential angle value. As a result, the opening is rotated downward, thereby allowing the bar 2 to roll out automatically.
[0033] In this way, the bar 2 is conveyed from the inclined plane 3 to the receiving area of the receiving unit 5 with low noise, because the bar is prevented from falling off the inclined plane 3.
[0034] During the descent of the lifting frame 4, other bars rolling on the inclined plane 3 are prevented from falling because the rod structure of the lifting frame 4 restricts the bars from reaching the lower end of the inclined plane 3. Only after the lifting frame 4 moves upward from the first lifting position to the second lifting position can the next bar 2 roll into the roller 20, which is brought to the corresponding circumferential position by the stepper drive device.
[0035] In other embodiments of the present invention, the stepper drive device 21 has an elastic element acting on the roller in a circumferential direction, wherein the elastic force generated by the elastic element is numerically greater than the weight of the rod 2, such that when the rod 2 rolls in, the roller 20 rotates from a first circumferential position to a second circumferential position, and further rotation to a third circumferential position can only be released by contact with the receiving unit 5. After the rod 2 rolls out of the roller 20, the elastic element pushes the roller 20 back to the first circumferential position.
