Description

[Detailed explanation of the invention] This invention involves transporting a steamer loaded with small fish by holding it close to the heel.
In a continuous small fish processing device equipped with a so-called steamer conveyor device, which passes through processing steps such as boiling and drying, empty steamers and steamers filled with small fish are transferred using a belt conveyor. This invention relates to a steamer feeding device for automatically feeding a steamer to the starting end of a conveyor device.

In any case, in a continuous small fish processing device equipped with a bamboo steamer conveyor device, it is necessary to feed the bamboo steamer to the starting end of the bamboo steamer conveyor device. As is well known, the bamboo steamer is
Because of their shallow bat-like shape, many steamers are usually stacked on top of each other before being fed to a conveyor device.

Therefore, in the past, workers had to completely remove one sheet from the stacked steamers and feed it to the starting end of the conveyor device, which was extremely inefficient, and efforts were made to mechanize the above-mentioned picking and feeding operation. However, there were various difficulties as follows.

In other words, with synthetic resin bat-shaped steamers, when the steamers are normally stacked, the upper steamers are fitted into the lower steamers in order, and especially with wooden steamers, the wire mesh stretched on the bottom Because the wire protrudes, it is difficult to mechanize it using a simple horizontal transfer device such as a pusher device, and even if a pick-up device with another mechanism (for example, a clamp device) is used,
For example, in the case of wooden steamers, the individual steamers are uneven in size, making it easy for clamping errors to occur, and the method of clamping the steamers from both sides has the problem of easily damaging the steamers. .

This invention overcomes the above-mentioned difficulties, has a simple structure, automatically picks up one steamer stacked in front of the starting end of the conveyor device, and transfers it to the starting end of the conveyor device. In particular, the stacked steamers are stacked on a lifting device for stacked steamers, and the steamers are stacked on the lifting device. Each time one of the highest ranking items is taken away,

Directly below the steamer lifting device 20 (solid line in the figure), steamers 2 are always stacked up and waiting, so each pair of torque motors 12, 12' is driven to lift the clamp arm. 14.14' by an appropriate angle in the opposite direction of the arrow in FIG.
When 14' is in the open state shown in FIG. 5, a gap of width α is created between each clamp arm 14 and 14', so in this state, the swing frame 4 is brought to the swing start position. The left and right frames 2a of the top steamer 2 are connected to each of the clamp arms 14.
, 14', and then if the clamp arms 14 and 14' are rotated in the direction toward each other (indicated by the arrows in Figure 5), the steamer 2 will be positioned within the interval α shown in Figure 6. As shown, four pairs of clamp arms 1 are used to hold the four parts of the frame 2a.
4.14' makes it securely clamped.

At this time, if the frame 2a of the steamer 2 is located within the distance α between the four pairs of clamp arms 14 and 14',
Even if the orientation and position of the steamer 2 are greatly deviated, for example as shown by the dashed line in FIG. 5, the clamp arm 14.
The frame 2a portion is reliably clamped by the clamping operation of the clamping device 14', and the steamer 2 held by the frame 11 of the clamping device 18 is then rotated forward and upward when the swing frame 4 swings forward and upward.
The clamping device frame 11 will be lifted upwards and transferred onto the front roller conveyor 1, but as described above, the clamping device frame 11 of this embodiment is fitted onto the second shaft 10. sprocket wheel 15
Since the sprocket wheel 16 fixed to the machine frame 5 has a larger diameter, the clamping device frame 11 that clamps the steamer 2 gradually tilts downward toward the front as it swings, and the roller conveyor 1, the roller conveyor 1 assumes the same inclination angle as the inclination angle.

When the clamp device frame 11 reaches the force button and the sea conveyor 1, the torque motors 12, 12' are driven in reverse to open the clamp arms 14 and 14' of each pair, and swing the swing frame 4 backward and upward. Once the steamer 2 is moved, it remains on the roller conveyor 1 and is conveyed to the next process by the roller conveyor 1.

As is clear from the above explanation, the steamer feeding device according to this invention uses the clamp device or the clamp arms eccentrically fitted to the motor shafts of multiple pairs of torque motors to separate the frame portions of the steamer from each other. Since the steamer is designed to be clamped, if the frame part of the steamer is located within the interval α between the clamp arms in the open state, there may be slight differences in the size of the steamers or the steamers may be stacked. Even if the bamboo steamers are not organized and are brought to the top in different positions and orientations, it is possible to reliably hold the steamers and separate them from the stacked steamers accurately. It can be transported by

The clamping device frame also includes a sprocket wheel fitted to the second shaft, a sprocket wheel fixed to the machine frame concentric with the first shaft, and a chain suspended between them. Since the control mechanism is provided, the steamer clamped by the clamping device is fed to the next process in a parallel movement with the net-shaped bottom facing downward without being reversed. When the diameters of the wheel and the 1 sprocket wheel are different, the attitude of the clamping device frame at the swing end position (shown by the two-dot chain line in Figure 1), i.e. the transfer of the clamped steamer to the next process. Another advantage is that the posture can be changed to any tilted posture.
