Description

[Detailed description of the invention] This invention relates to a device for transferring bread to a spreading plate in a bread making line, and automatically arranges the products that are aligned and conveyed after unwrapping work etc. on the spreading plate in the bread manufacturing process. The present invention relates to a device for transferring bread to a spreading plate in a bread making line.

In the bread manufacturing process, there is work such as unwrapping and shaping the bread, arranging it on a rolling board and moving it to the next process. Although it depends on the capacity of the equipment, the work of arranging the sheets on the spread plate is usually done manually by at least two people.

This idea was devised for the purpose of mechanizing the above-mentioned work of arranging products on a spreading plate, improving efficiency and automation in the bread-making process, and contributing to streamlining the production line. ,
A horizontally movable driven shaft and a drive shaft connected to a drive part via a brake part are mounted parallel to each other in a horizontal plane within the machine frame, and a transfer belt is provided that is endless around these horizontally movable driven shaft and drive shaft. and an outwardly movable driven shaft is mounted near the drive shaft within the transfer belt, and the horizontally movable driven shaft is movable in the horizontal plane and in the belt conveying direction while remaining parallel to the drive shaft. The horizontally moving driven shaft and the outwardly moving driven shaft are provided to be movable outward of the transfer belt while being parallel to the drive shaft, and the horizontally moving driven shaft and the outwardly moving driven shaft are linked to a moving mechanism. The moving mechanism is made to operate when the drive shaft is stopped.

An embodiment of this invention will be described below based on the drawings.

In the figure, 1 is a machine frame, and within this machine frame 1, a receiving belt 2 for receiving a product B from a workpiece conveyor A, and a transfer belt 3 continuous with this receiving belt 2 are arranged horizontally.

The transfer belt 3 is an endless belt with excellent flexibility, and is looped around a horizontally moving driven shaft 4 and a drive shaft 5 that is connected to a drive section (both not shown) via a brake section. An outwardly movable driven shaft 6 is mounted in the vicinity of the drive shaft 5 within the transfer belt 3.

The horizontally moving driven shaft 4 is provided parallel to the drive shaft 5 and movable in the same horizontal plane as the drive shaft 5 and in the belt conveyance direction. That is, for example, a guide path 7 is horizontally formed with a rail or the like on the side plate of the machine frame 1, and a shaft support 8 is provided to be guided by this guide path 7.
The shaft support 8 supports the shaft end of the driven shaft 4 and is movable in a horizontal plane. Similarly, a shaft support 8 is provided which is guided by a guide path (not shown) so that the outwardly movable driven shaft 6 also moves downward, and this shaft support 8 supports the shaft end of the driven shaft 6. It is movable downward.

Further, the shaft support 8 is provided with a moving mechanism. The moving mechanism connects the shaft supports 8 on the same side plate of the machine frame 1 with an endless chain 9, loops the chain 9 around a sprocket 10, and synchronizes the chains 9 on both sides. It is formed in conjunction with a drive section (not shown). Therefore, each driven shaft 4, 6
can move while always maintaining parallel to the drive shaft 5.

The drive section, brake section, and moving mechanism of the drive shaft 5 are controlled by a control mechanism (not shown). The control mechanism connects a detection switch consisting of a sensor etc. that detects the product B on the belts 2 and 3 and a switch (both not shown) that confirms the position of each driven shaft 4 and 6, and controls the drive section of the drive shaft 5. and actuates the brake section and the drive section of the moving mechanism. That is, the product B conveyed from the receiving belt 2 is detected near the connection between the receiving belt 2 and the transfer belt 3, and the signal is used to operate the motor of the drive unit to rotate the transfer belt 3 and receive the product B. Transfer from belt 2 to transfer belt 3. When the product B on the transfer belt 3 is conveyed to a predetermined position, the product B is detected and the drive shaft 5 is stopped. Next, the product B sent from the receiving belt 2 is received again in the same manner as described above, and the transfer belt 3 is rotated to convey it to a predetermined position. By repeating this process, a plurality of product rows are arranged on the transfer belt 3 at predetermined intervals. A counting section (not shown), such as a counter, is formed in the control mechanism and stores the number of rows of the products, and when a predetermined number of rows is reached, a signal is issued to divide the group consisting of the rows of products. It is conveyed to a predetermined position (a position above the spreading plate C that is moved and placed below the transfer belt 3), and then the transfer belt 3 stops rotating. At the same time,
The driving part of the moving mechanism operates and the horizontally moving driven shaft 4 moves toward the driving shaft 5, and the outwardly moving driven shaft 6 moves outward (in the illustrated example) in response to the movement of the horizontally moving driven shaft 4. (downward). Therefore, as the horizontal movement driven shaft 4 and the outward movement driven shaft 6 move, the horizontal surface portion of the transfer belt 3 decreases, and since the rotation of the drive shaft 5 is braked by the brake section, the transfer belt 3 does not rotate, so the product B falls onto the spreading plate C below as the horizontal surface decreases without changing its relative position with respect to the spreading plate C.

Incidentally, the transfer belt 3 is provided with a take-up unit (not shown) for adjusting the tension of the belt as necessary.
This prevents the belt from slipping. Also,
In the figure, reference numeral 11 denotes a guide roller that guides the transfer belt 3 when it is projected outward by the outward moving driven shaft 6. This roller 11 is elastically inwardly repelled by a coil spring or the like (not shown). The take-up unit may also be formed by pressing it down.

Further, the above-mentioned receiving belt 2 is provided with a deceleration switching mechanism (not shown) so that its conveyance speed can be switched to two stages. Therefore, the receiving belt 2 first rotates at the same speed as the workpiece conveyor A and receives the shaped product B sent from the workpiece conveyor A. When the product B is completely transferred to the receiving belt 2, the receiving belt 2 increases its rotation and rapidly transports the product B to the transfer belt 3. The transfer of the product B from the receiving belt 2 to the transfer belt 3 is also carried out by rotating the transfer belt 3 at the same speed as the receiving belt 2 in the same manner as described above. When this transfer is completed, the receiving belt 2 rotates at the original speed, that is, the same speed as the workpiece conveyor A, and waits for the next product B. Such receiving belt 2
By providing this, the conveying speed of the conveying belt 3 can be increased and processing capacity can be improved. Moreover, product B can be transferred reliably between the belts, and product B can be transferred between belts.
Never break the line.

In other words, when transferring product B, especially semi-finished products (unsolidified dough, etc.) during production, it is important to ensure that the speed of each belt is the same to ensure that the product itself and the product row retain their shape. Therefore, if the transfer belt 3 is directly connected to the workpiece conveyor A, the transfer speed of the transfer belt 3
However, if the receiving belt 2 is provided, the conveyance speed of the transfer belt 3 can be increased compared to the workpiece conveyor A, and the throughput can be improved. It is.

In addition, D in the figure is a spread plate supply chain conveyor that conveys the spread plate C to a predetermined position below the transfer belt 3, and E in the figure is a spread plate discharge chain conveyor that conveys the spread plate C on which the spread plate B is placed to the next process. It is.

Constructed as described above, in the horizontal plane inside the machine frame 1,
A horizontally movable driven shaft 4 and a drive shaft 5 connected to a drive part via a brake part are mounted parallel to each other, and an endless transfer belt 3 is wrapped around these horizontally movable driven shaft 4 and drive shaft 5. And this transfer belt 3
An outwardly movable driven shaft is mounted near the inner drive shaft 5, and the horizontally movable driven shaft 4 is provided so as to be movable in the horizontal plane and in the belt conveyance direction while remaining parallel to the drive shaft 5. The horizontally moving driven shaft 6 is provided so as to be movable outwardly of the transfer belt 3 while remaining parallel to the drive shaft 5, and these horizontally moving driven shaft 4 and outwardly moving driven shaft 6 are linked to a moving mechanism. Since the moving mechanism is made to operate when the drive shaft 5 is stopped, the product B can be accurately and reliably dropped and placed at a predetermined position on the spreading plate C placed below the transfer belt 3. . Moreover, since the horizontal surface portion of the transfer belt 3 is reduced and dropped by the movement of the horizontally moving driven shaft 4, the device configuration can be made simple and compact, and the head difference between the top surface of the transfer belt 3 and the spreading plate C can be reduced. Not only does it not cause deformation of product B due to its small size, it also does not destroy the product line.

In addition, since it can be dropped and placed without touching the product B, it is extremely hygienic.

Furthermore, since the drive shaft 5 is connected to the drive section via the brake section, the transfer belt 3 will not rotate when the horizontal surface area decreases. Therefore, the product B can reliably fall to a predetermined position on the spreading plate C without changing its relative position with respect to the spreading plate C.

As explained above, according to this invention, unwrapped products, etc. can be reliably and accurately dropped to predetermined positions on the spreading plate in the bread making process, and the work of arranging them on the spreading plate manually as in the past can be avoided. This is an extremely useful idea in practical terms, as it can be done extremely hygienically without the need for it, improves work efficiency and automates the production line, and contributes to the rationalization of the bread-making process.
