Description

A known hanging dryer for drying the skins on the frames, consisting of a horizontally positioned frame fixed on the frame of the chamber for heating the air, including a fan and a heater mounted in the frame of a two-valued closed conveyor, hooks are attached to the chain links for hanging frames with skins secured in the frame of the upper and lower guides for the frames and the drive.

In this dryer, the frames with leathers are hooked onto the conveyor hooks manually, and the air preheating chamber is mounted on one side of the dryer, which prevents an increase in the intensity of skin drying and a reduction in the number of frames.

In the described overhead dryer these disadvantages are eliminated. In it, for the automatic capture of frames with leathers when moving from workplace B to the drying chamber and from the end of the drying chamber to the workplace, the transparter is equipped with figured plates mounted into each of its DE.um chains, each of which replaces two chain links with hinged there are hooks on them, which serve to grip the frames, and rollers rotating on the hooks, interacting with guides installed in the path of the conveyor, ensuring that the hooks turn and guide the frames into the slots of the figured planes. ting, in which the frame is transmitted from the drying chamber to a workstation and from a workstation in suschilnuyu camera, but in order to accelerate the drying chamber for leathers podogreE.a air dryer set at both ends.

from the frame, on which are fixed at both its ends of the chamber 2 for heating the air. Each chamber 2 has an axial fan 3 and a heater 4. In the frame of the dryer 1, a closed double-chain conveyor 5 is mounted. It is pulled over four pairs of sprockets 6, -7, 8 and 9, of which BZ-6 is rigidly seated on the shaft 10 and are leading, sprockets 7 are tensioned and can move in the horizontal direction under the action of tension bolts 11. The remaining two pairs of sprockets 8 and 9 freely sit on the pinch x attached to the frame of the cigar 1. The double-chain conveyor 5 receives movement from the electric motor 12 through gearbox 13 and chain drive 14.

In order to automatically grip the frames 15 with leathers, the conveyor 5 is provided with a built-in data in each of its chains with two figured plates 6, each of which replaces two chain links. The plates 16 carry hooks 17 hinged on them that grip the suspensions ifi frames 15. The hooks 17 are provided with rotating rollers IV, cooperating with guides 20 and 21 installed in the conveyor path 5 to turn the hooks 17 and guide the suspensions 18 of the frames 15 into the grooves 22 shaped plates 16, EI of which frame 15 with leather is transferred from substance 1 to a work station for fastening leathers and from a work station to a surface 1.

Suspension 18 of each frame 15 carries rollers 23 at the ends of its horizontal rods, supported by guides 24 mounted inside a substance L To each horizontal rod (suspension 18) vertical rods are rigidly attached on both sides, terminating in sockets under the trunnion of frame 15 and buffers 25, defining the pitch between adjacent frames 15 in the nest. On the upper horizontal rod of each suspension 18, two clamps 26 are installed, which fix the position of the frame 15 in the suspension 18 in a vertical position. The tabs 26 consist of a spring-loaded lever 27, carrying a roller 28 at its free end and hingedly connected to a rod 29 terminating in a fork with a rotating roller 30. When the frame 15 is rotated. Within the suspension bracket 18, the roller 30 enters the slot of the bevel 31 fixed to the frame 15, fix the last upright.

Work on the overhead dryer when drying the leather is as follows.

Before moving the frame 15 into the substance / on it, the skin is fixed, placing for this the frame 15 into the device 32 for releasing and automatically fixing the frames in a horizontal position. Then, the pedal 33 of the device 32 is depressed and the frame 15 with leather is brought into a vertical position. In this case, the frame 15 with a bevel bevel 31 presses on the roller 30 of the lock 26. The roller 30 drops into the hole of the bevel 31 by fixing the frame 15 inside its suspension 18 in a vertical position. After that, an electric motor 12 is turned on, which drives a double-chain conveyor 5. At the same time, the figured plates 16 of the conveyor 5 capture the suspension 18 of the frame 15 and transport the frame 15 into the existing chamber 1. At the top of the dryer / suspension 18 with the frame 15, the sprocket 9 rolls around the suspensions 18 slide out of the grooves 22 of the plates 16, and the suspension 18 with the frame 15 rolls down the rollers 23 onto the guides 24 until its buffer 25 is bumped into the buffers of the previous frame. At the same time, the roller 19 finds the directional 20, raises the hook 17 and the figured plates 16 passes over the suspensions 18 without touching them.

At that time, when the figure 16 of the moving conveyor 5 is fed to the frame 1, the frame 15 is fed in, the second pair of figured plates 16 approaches the guides 21 (shown in Fig. 3 by a dotted line). Wherein

the roller 19 is lowered together with the hooks 17, which grip the suspension 18 of the frame 15 in such a way that the ends of the suspension 18 move into the grooves 22 of the plastic 16. The frame 15 captured by the figured plates 16 bypasses the asterisk 8 and lowers along the vertical branch of the guide 24. Upon encountering pin 34- on its way, frame / 5-tilts, roller 28 of lock 26 locates on guide 35, due to which lever 27 raises rod 2i with roller jf and it comes out of bevel hole 5 / frame 15, freeing it from vertical fixation in the suspension. and the conveyor drive 5 at the approach of the frame 15 to the workplace under the dryer is turned off by a limit switch (not shown in the drawing). The released frame 15 with the treated skin is manually brought into the horizontal position and so it is fixed in the device 32. The treated skin with the frames 15 is removed, the new skin is filled in its place, the frame 15 is again placed in the vertical position inside the suspension 18 as described above, include motor 12, which drives the movement of the conveyor 5. The conveyor 5 introduces the frame 15 into the dryer 1 and the cycle continues in the same order.

The subject matter of the invention 1. A hanging dryer for drying skins on frames, consisting of a horizontal frame fixed to the frame of the chamber for heating the air, including a fan and a heater mounted in the frame of a double-chain closed conveyor, to which chain links are attached hanging

frames with skins fixed in the frame of the upper and guides for the frames and the drive, characterized in that, in order to automatically grip the frames with the skins when moving the frames from the workplace to the drying chamber and from the end of the drying chamber to the workplace, the conveyor is equipped with built-in B. Each of its chains with two figured plates, each of which replaces two chain links, carrying hooks attached to them pivotally attached to them, and rollers rotating on the hooks, interacting with movement mounted on the track. The guide rails guide the hooks, and the frames are guided into the grooves of the shaped plates in which the frame is transferred from the drying chamber to the workplace and from the working place to the drying chamber.

2. The form of the dryer according to claim 1,., Is about the fact that, in order to accelerate the drying of the leather, air heating chambers are installed at both ends of the dryer.
