It is supported. On the other hand, in the second belt conveyor 12, the first idle pulley 43 is rotatably supported by the connecting member 54, and the second to fifth idle pulleys 44 to 47 are rotatably supported by the frame 2. Therefore, when the connecting members 53 and 54 move integrally, the end members 32 and 41 and the idle pulley 3
4 and 43 are also configured to move together. As a result, the slack or elongation of the conveyor belts 21 and 22 caused by the movement of the end members 32 and 41 is absorbed by the change in the shape of the conveyor belts 21 and 22 caused by the movement of the idle pulleys 34 and 43. Will be.

Further, above the vicinity of the downstream end of the first belt conveyor 11, a conveyed object detecting sensor 58 for detecting the passage of the sheet-like confectionery W is provided. When the passage of the confectionery W is detected, it is determined that the transfer of the confectionery sheet from the first belt conveyor 11 to the second belt conveyor 12 is started. At this timing, the first rotating disk 57 is rotationally driven, whereby the connecting members 53 and 54 and the connecting rod member 55 are moved in the transport direction, and the vicinity of the downstream end of the first belt conveyor 11 and the second The transfer of the sheet-like confectionery is performed by partially moving the vicinity of the upstream end of the belt conveyor 12 to widen the conveyance interval.

Pulley support portion 67c for rotatably supporting the idle pulley 63 of FIG.
2 is attached and fixed. The support member 67
Is mounted on a movable member 68 which is slidably supported in the transport direction. Although the third belt conveyor 13 is configured so that the downstream end is inclined so that the transfer of the sheet-like confectionery is smooth, the downstream end may be in a horizontal state. Although not specifically shown, the movable member 68
Are slidably engaged with guide rails and guide rods arranged vertically in the transport direction.

One end of a connecting rod member 69 is rotatably connected to the movable member 68, and the other end of the connecting rod member 69 is connected to a second position located upstream in the transport direction.
Is rotatably connected to the rotating disk 70 of the first embodiment. Therefore,
When the rotating disk 70 is rotationally driven by a driving means (not shown), the downstream end of the third belt conveyor 13 partially moves when the movable member 68 moves in the transport direction. . Therefore, the third belt conveyor 13 is configured as a floating type in which the downstream end can be partially moved by moving the belt receiving member (the second end member 62 and the support member 67) in the transport direction. It will be. In addition, since the second end member 62 and the first idle pulley 64 are supported by the common movable member 68, the slack and the elongation of the conveyor belt 23 are increased in the same manner as in the case of the deflection absorbing means described above. Is absorbed in the vicinity of the first idle pulley 64.

The fourth belt conveyor 14 has an end pulley 71 and an end member 7 located at the upstream and downstream ends thereof.

Further, first and second idle pulleys 73 and 74 are provided between the first end pulley 71 and the drive pulley 20, and a third idle pulley is provided between the end member 72 and the drive pulley 20. 75 are provided respectively. An elevating plate 81 is provided below a portion of the fourth conveyor belt 24 that receives the sheet-like confectionery W from the third belt conveyor 13. By means, the sheet confectionery W is moved up and down in accordance with the number of sheets confectionery W to be stacked.

Above the downstream end of the third belt conveyor 13, a conveyed object detection sensor 59 for detecting passage of the sheet-shaped confectionery W is provided. When the passage of the class W is detected, the third
It is determined that the operation of transferring and stacking the sheet-like confectionery W from the belt conveyor 13 to the fourth belt conveyor 14 is started, and the control means (not shown) controls the second rotating disk at a certain timing. 70 is driven to rotate,
By moving the movable member 68 forward and backward in the transport direction, the vicinity of the downstream end of the third belt conveyor 13 is partially moved, and the fourth belt conveyor 14 is moved.
The sheet-shaped confectioneries W are sequentially stacked on the portion for receiving the sheet-shaped confectionery W (the upper part of the elevating plate 81). At this time, in addition to the step of raising and lowering the lifting plate 81, the fourth belt conveyor 14 moves up and down stepwise in accordance with the number of stacked articles, and the fourth belt conveyor 14 When receiving the sheet-like confectionery, the conveyor belt 2 is moved so that the portion for receiving the sheet-like confectionery moves forward and backward in the transport direction.
4 runs.

Subsequently, the first to fourth belt conveyors 1
The transport operation using 3 to 16 will be described. (Operation for Adjusting Conveyance Interval) First, a sheet of a large confectionery is cut into a required size to form a sheet-like confectionery. It is transported at the speed V1.

When the sheet-like confectionery reaches the vicinity of the downstream end of the first belt conveyor 11, the passage of the sheet-like confectionery W is detected by the conveyed object detection sensor 58, and the first belt conveyor 11 outputs the confectionery. Second belt conveyor 12
It is determined that the transfer of the sheet-like confectionery to the start is started, and the control means (not shown) starts the rotation driving of the first rotating disk 57 at a certain timing. The rotation of the first rotating disk 57 causes the connecting rod member 5 to rotate.
6, connecting members 53 and 54 and connecting rod member 55
Are moved to the first belt conveyor 11 side in the transport direction, and the vicinity of the downstream end of the first belt conveyor 11 and the vicinity of the upstream end of the second belt conveyor 12 are partially and integrally moved, Transfer of sheet-shaped confectionery is performed smoothly without difficulty.

Specifically, the connecting member 5 as the connecting means
Due to the movement of the connecting rod members 55 to the first belt conveyor 11 side, first, the downstream end of the first belt conveyor 11 and the upstream end of the second belt conveyor 12 move. become. At this time, the moving speed is a speed substantially corresponding to a speed difference between the second set speed and the first set speed (that is, the first set speed).
When viewed locally at the connection portion between the second belt conveyors 11 and 12, the downstream end of the first belt conveyor 11 retreats at the moving speed (first set speed) of the connecting members 53 and 54 and the like. And the upstream end of the second belt conveyor 12 is driven by the traveling speed of the second belt conveyor 12 (the second set speed) such that the moving speed of the connecting members 53 and 54 (the first set speed). ), So that the second conveyor belt 22 operates as if it is rotating at the first set speed.

As a result, the sheet-like confectionery W to be transferred from the first belt conveyor 11 to the second belt conveyor 12 is moved backward from the end by the retreat of the downstream end of the first belt conveyor 11. The sheet-shaped confectionery is continuously delivered at the set speed of 1 and is received by the upstream end of the second belt conveyor 12 which is rotating at the first set speed. Transfer is performed without any unnecessary force acting on W. After the transfer, the portion other than the upstream end of the second belt conveyor 12 has the second conveyor belt 12 running at the second set speed higher than the first set speed, so that the transfer interval is shorter. The sheets are spread and conveyed, which is a conveyance interval necessary for performing the following stacking.

As described above, the transfer interval of the sheet-like confectionery W is widened when the sheet confectionery W is transferred from the first belt conveyor 11 to the second belt conveyor 12.
Is transferred to the belt conveyor 13. At this time, since the second belt conveyor 12 and the third belt conveyor 13 are driven to rotate at the same speed, the transfer of the sheet-like confectionery from the second belt conveyor 12 to the third belt conveyor 13 is performed. , Without disruption. (Stacking operation) The sheet-like confectionery W being conveyed by the third belt conveyor 13 is located near the downstream end.
By the forward and backward operations, a predetermined number of sheet-like confectioneries W are sequentially stacked on the receiving portion of the fourth belt conveyor 14.

Specifically, the sheet-like confectionery W is the third confectionery.
2 reaches the vicinity of the downstream end of the belt conveyor 13 of FIG.
As shown in (a) and (b), the passage of the sheet confectionery W is detected by the conveyed object detection sensor 59 (see FIG. 1), and the fourth
It is determined that the stacking of the sheet-like confectionery W on the belt conveyor 14 is started, and the control means (not shown) rotates the second rotating disk 70 at a certain timing to convey the movable member 68. Move in the opposite direction. That is, the downstream end (end member 62) of the third belt conveyor 13 is retracted by a certain distance. At the same time, the conveyor belt 24 of the fourth belt conveyor 14 also travels by a certain distance in the transport direction.

With the retreat of the downstream end of the third belt conveyor 13, the sheet-like confectionery W is placed on the receiving portion of the fourth belt conveyor 14, as shown in FIGS. 3 (a) and 3 (b). . At this time, since the conveyor belt 24 of the fourth belt conveyor 14 is also configured to travel in the transport direction by a certain distance, a force in the transport direction acts on the first portion of the sheet-shaped confectionery. Is placed along the conveying surface of the conveyor belt 24, so that the above-mentioned portion does not bend downward and round.
If the sum of the moving distances of the downstream end of the third belt conveyor 13 and the fourth conveyor belt 24 is a distance substantially corresponding to the length of the sheet confectionery, useless movement is eliminated.

Then, after the transfer is completed, until the transfer of the next sheet-like confectionery is started, the vicinity of the downstream end of the third belt conveyor 13 moves forward, and changes as if the downstream end of the bell conveyor is extended. Therefore, the next sheet-like confectionery is in a state where it is partially retracted with respect to the downstream end, and the transfer does not affect the next sheet-like confectionery.

In this manner, the fourth belt conveyor 14
After the sheet-shaped confectionery is placed on the upper side, the downstream end of the third belt conveyor 13 and the conveyor belt 24 move in opposite directions, and as shown in FIGS. (A position where the downstream end of the third belt conveyor 13 is opposed to the end of the confectionery) and a lifting plate (not shown) moves up and down by a distance corresponding to the thickness of the confectionery. 81 descends and the downstream end and the fourth end
Is increased by a distance corresponding to the thickness of the sheet confectionery.

The same operation is repeated (FIG. 5)
(See (a) and (b)), the required number of sheet-shaped confectioneries are stacked. After the sheets are stacked, they are moved by a predetermined distance and stopped by the fourth belt conveyor 14, and the next stacking operation is performed. This is repeated, and a predetermined number of sheets are sequentially conveyed to the next step (not shown) (see FIGS. 6A and 6B).

In the above embodiment, the feed conveyor is constituted only by the third belt conveyor 13, but the first conveyor for conveying the conveyed articles at a constant conveyance interval, and the first conveyor A second conveyor may be provided below the downstream end to receive the conveyed product from the first conveyor.

In this case, as shown in FIG. 7, the first and second conveyors 101 and 102 are respectively composed of first and second idle pulleys 103 and 102 forming an upstream end and a downstream end.
104, 105, 106, and the driving pulley 10
7 and 108, and third and fourth idle pulleys 109, 110, 111 and 112, and conveyor belts 113 and 114 are rotatably provided. Then, the first and second idle pulleys 105 and 106 of the second conveyor 102 are linked to the end moving means, and the two idle pulleys 105 and 106 move integrally, whereby the second conveyor 102 is moved. Is moved in the transport direction.

In this way, both conveyors 101, 1
When the sheet-like confectionery is transferred from the first conveyor 101 to the second belt conveyor 14,
From the start to the end of the transfer of the sheet-like conveyed material to the first conveyor 102, the second idle pulley 106 constituting the downstream end of the second conveyor 102 is transferred to the first conveyor 101 together with the first idle pulley 105. In the conveying direction (the fourth belt conveyor 14 which is a receiving conveyor)
Side), while receiving the conveyed material from the first conveyor 101, the leading end of the sheet-shaped confectionery does not bend when transferring to the second conveyor 102. When the transfer is transferred from the second conveyor 102 onto the fourth belt conveyor 14 after the transfer, the second conveyor 102
From the start of transfer of the conveyed object to the fourth belt conveyor 14 to the end of transfer, the first and second idle pulleys 105 and 106 of the second conveyor 102 are both the first idle pulleys 105 and 106.
The sheet-like confectionery is transferred onto the fourth belt conveyor 14 while moving in the direction opposite to the conveyance direction with respect to the conveyor 101, and after the transfer is completed, the confectionery is moved in the conveyance direction until the transfer of the next conveyed object is started. Thus, it is possible to stack the confectionery sheets in order without causing any disorder. In the second conveyor 102, since the first and second idle pulleys 105 and 106 move together, the belt does not slack.

In the above embodiment, when the sheet-like confectionery is stacked by the third belt conveyor 13 which is the feeding belt conveyor, the receiving portion of the fourth belt conveyor 14 which is the receiving conveyor is moved in the transport direction. Although not intended to be limiting, the invention is not so limited and it is possible to move only the downstream end of the infeed belt conveyor and leave the receiving belt conveyor stationary.

In the above embodiment, when the third belt conveyor 13 serving as the feed conveyor stacks the confectionery sheets, the receiving portion of the fourth belt conveyor 14 serving as the receiving conveyor is moved up and down by the elevating plate 81.
Although the receiving part is raised and lowered by utilizing the present invention, the present invention is not limited to this, and it is also possible to raise and lower the entire receiving belt conveyor. Formed between the belt conveyor and the receiving belt conveyor, it is also possible to prevent the receiving part of the receiving belt conveyor from rising and falling unless it is too large.

Is moved partly, so that the conveyed goods are sent from the belt conveyor and transferred on the conveyor smoothly without applying excessive force as if a skilled person holds it by hand, It can be automatically stacked in order. By the elevating means, since the portion of the receiving belt conveyor that receives the conveyed material is configured to be stepped up and down in accordance with the number of laminations of the conveyed material,
The distance between the downstream end portion of the feed belt conveyor and the portion for receiving the conveyed material is reduced, and the impact when transferring from the feed belt conveyor to the receiving belt conveyor is further reduced.

According to a second aspect of the present invention, when the article is transferred from the infeed belt conveyor to the receiving belt conveyor, the article is first transferred from the infeed belt conveyor to the receiving belt conveyor by the end moving means. From the start to the end of transfer, the downstream end of the feed belt conveyor is moved in the reverse direction to the transport direction, and after the transfer is completed, in the transport direction until transfer of the next transported object is started. The transfer belt can be moved from the infeed belt conveyor to the receiving belt conveyor without exerting excessive force, and can be stacked in the same manner as a manual operation by a skilled person.

According to the third aspect of the present invention, since the belt receiving member which is located below the conveyor belt near the downstream end of the feed belt conveyor and forms a belt turning point is provided, the belt receiving member is moved. Thus, the vicinity of the downstream end of the feed belt conveyor can be partially and easily moved, and the change in the deflection of the conveyor belt caused by this partial movement includes the first and second idle pulleys. It can be absorbed by the flexure absorbing means and does not affect the conveyance of the conveyed object.

According to a fourth aspect of the present invention, when the receiving belt conveyor receives a conveyed product from the infeed belt conveyor, at least a portion for receiving the conveyed product moves forward and backward in the conveying direction. In this case, the leading ends of the sheet-like conveyed products can be prevented from being bent downward, and can be stacked neatly.

According to a fifth aspect of the present invention, a downstream end portion of a feed belt conveyor which conveys a conveyed article at a constant conveyance interval on a receiving belt conveyor is moved forward and backward in the conveying direction, thereby providing a downstream side of the feed belt conveyor. Because we move part near the side end part,
Similar to the first aspect, the objects can be stacked regularly without exerting an excessive force on the objects.

According to a sixth aspect of the present invention, while the downstream end of the second conveyor is moved in the conveying direction with respect to the first conveyor, the conveyed article is once received from the first conveyor, and then the first conveyed object is moved to the first conveyor.
The transfer belt conveyor is configured so that the transfer object is transferred to the receiving belt conveyor while moving in the direction opposite to the transfer direction with respect to the conveyor of, so that the transfer of the transfer object due to the movement of the transfer belt conveyor is not disturbed. Can be avoided.
