First, I will briefly explain the separation station B, which separates cake pieces sliced in the thickness direction and layered in the vertical direction in the front-to-back direction in order to apply a creamy confectionery material to the top surface of each cake piece. In the figure, 1 is a transfer comparer that circulates near the upper end of the frame 2 to form a cake piece transfer path R, and 3 is a transfer comparer that circulates near the upper end of the frame 2 to form a transfer path R for the cake pieces. A pair of left and right rails 4 are arranged in parallel along the direction of movement, and are constructed so as to be slidable on the rail 3, and move parallel to the front in synchronization with the transfer conveyor 1 via a chain 5, and to the rear. A base plate 6 is rotatably supported perpendicularly to the base plate 4 and is driven to rotate in forward and reverse directions by a motor 7. A screw shaft 8 is located near the upper end of the screw shaft 6. This support frame is screwed together and is moved up and down by the forward and reverse rotation of the screw shaft 6. The upper part thereof is formed in a front shape, and surrounds both sides and the lower surface of the transfer conveyor 1.

The racks 14 to 14 are engaged with each other and are moved forward and backward in a symmetrical inclined manner, and the upper part k of the cake layer k is provided at the tip of each rack 14 in order to pierce the upper surface of the cake layer k in an inclined manner from the front-rear direction or the left-right direction. When the cake layer k, which is equipped with fixed separation needles 15 to 15, etc. and is transferred in layers on the transfer conveyor 1, passes below the separation unit 9, this passage is detected and the base plate 4 is transferred. While starting to move forward in synchronization with the conveyor 1, each separation needle 15 is rotationally controlled via a rotary encoder 10 so as to pierce the upper layer k of the cake layer k, leaving the bottom cake piece k2. Motor 1
1, each separation needle 15 moves forward and pierces the upper layer k while following the passage of the cake layer k, and furthermore, each separation needle 15 raises the upper layer k and leaves behind the cake layer k. A series of separation operations in which the cake layer k is rapidly retracted together with the base plate 4 and moved up and down together with the support frame 8 are repeated, and the cake layer k is spaced apart from each other in the front and back direction on the transfer comparer. It is separated and transported forward from separation station B.

A pair of left and right rails are arranged in parallel along the moving direction of the transfer conveyor 1 downward near a, and on the upper side, a rectangular base plate 18 extends in the front and back direction via sliding pieces 19 to 19. It is horizontally mounted so that it can slide.

It is a double clutch brake disposed behind the base plate 18, and its output shaft 20a is rotatably driven to be stopped via an electromagnetic clutch by a first motor (not shown) for driving the transfer conveyor 1. The forward rotation of the intermediate shaft 21 and the reverse rotation of the second motor 22 provided in front of the double clutch brake 20 are selectively transmitted, and the output shaft 20a is rotationally driven in the forward and reverse directions.

Reference numeral 23 denotes a chain for driving the base plate 18, which is iron-bonded to the output shaft 20a of the double clutch brake 20, and then connects to a sprocket wheel 24 and a front sprocket wheel 26 rotatably supported near the front end of the wheel 17. When the leading cake piece of the cake pieces that is hung on the base plate 18 and is connected to the front and rear ends near the center of the base plate 18 and is separated and transferred in the front and rear direction passes near the starting end of the stacking station J. The double clutch brake 20 is excited by the signal from the first detection device 37 to detect this passage, the output koji 20a rotates forward, and the base plate 18 moves forward in synchronization with the transfer conveyor 1 via the chain 23. While moving in parallel, when the double clutch 20 is demagnetized and the second motor 22 is activated at the end of this parallel movement, the chain 2
3, the base plate 18 is moved backward at an increased speed compared to when it is moving forward.

Reference numeral 26 denotes a screw shaft that is rotatably supported perpendicularly to the center of the base plate 18, and a third motor that is attached to the lower surface of the base plate 18 and whose rotation is controlled via a rotary encoder 27. 28, which is rotated in the forward and reverse directions, and has a threaded portion 26a formed near the top thereof, and when the cake pieces reach the vicinity of the front end la of the transfer conveyor 1, the third
A second detection device 38 provided near the front end la of the motor 28
is activated by the detection signal, and the screw steel 26 is rotated in the forward direction for a predetermined period of time.

Reference numeral 29 denotes a support stand that is screwed onto the threaded portion 26a of the screw steel 26 and is disposed above the base plate 18 so as to be movable up and down via guide pieces 30, 30, and is capable of rotating the screw shaft 26 in the forward and reverse directions. The right and left threads are screwed into the right and left threads of an adjusting screw 31, which is rotatably operated via a handle 31a, on both sides of its upper surface, and are compressed into the same zero shape. Leg pieces 32, 32 are erected to face each other with the transfer conveyor 1 in between.

Reference numerals 33 to 33 designate a plurality of pairs (three pairs in this example) of air cylinders that are arranged in parallel to face each other with the support frame 34 interposed between the upper ends of both leg pieces 32, and a sliding cylinder 33a is provided at the back portion of the air cylinders. Each of them is equipped with iron so that it can move forward and backward in a direction perpendicular to the cake piece transfer path R, and is moved substantially in synchronization with the movement of the base plate 18.

Reference numerals 33 to 35 indicate stinging needles attached in a cantilevered manner to the lower end of each sliding tube 33a, and when the sliding tube 33a advances or retreats, the base plate 18 moves in parallel with the cake piece and synchronizes with the cake piece. While moving in the transfer direction of the cake piece, it is projected toward the side of the cake piece, and the cake piece is pierced by each puncture needle 35 from both sides so that it can be raised and transferred.

Reference numeral 36 denotes a double mirror conveyor installed in front of the front end la of the transfer conveyor 1, which is stopped during the loading operation of cake pieces, and is circulated when transferring the stacked cake pieces to a subsequent process (not shown). Rotated.

39 is a third detection device, which detects when the cake pieces pierced by the pricking needle 35 and carried out to the front of the transfer conveyor 1 reach a predetermined volume position L on the cloud accumulation stage 36. The electromagnetic clutch of the drive system of the intermediate shaft 21 is demagnetized by this detection signal, and the rotation of the output shaft 20a of the double clutch brake 20 is stopped. , the movement of the base plate 18 and the stabbing needle 35 is stopped, and the detection signal is input to the rotary encoder 27, the third motor 28 is reversely rotated for a predetermined period of time, and the stabbing needle 35 is moved through the support base 29. After leaving work, the cake pieces are placed in the drying position L.

Furthermore, after the cake piece has been placed in place, the sliding tube 33a of the air cylinder 33 is retracted by the output signal of the rotary encoder 27, the puncture needle 35 is removed from the cake piece, and the second motor 22 is activated. Then, the double clutch brake 20 is demagnetized, the output shaft 20a starts to rotate in reverse, and the stinging needle 35 that moves together with the base plate 18 retreats backward along the transfer path R and returns to its original position, and the leading cake piece is removed. Wait for the subsequent cake piece to pass through. Next, a method of implementing the present invention using the apparatus having the above-described configuration will be explained.

First, when the leading cake piece K among the cake pieces K separated and transferred in the front-back direction reaches the dosing station J, it moves forward in synchronization with the transfer conveyor 1 based on the detection signal of the first detection device 37. Along with the base plate 18 being moved in parallel, each needle 35 synchronizes with the leading cake piece K and starts parallel movement in the moving direction of the leading cake piece K, and during this movement, the sliding tube 33a of the air cylinder 33 moves. As the needles move forward, each needle 35 projects in a direction across the cake piece transfer path R, and the leading cake piece K is pierced from both sides.

Then, the leading cake piece K, is the front end la of the transfer conveyor 1.
, that is, when the needle 35 reaches near the end of its parallel movement,
The third motor 28 is started to rotate forward in response to a signal from the second detection device 38, and each pricking needle 35 moves upward, and the leading cake piece K is raised to the car stacking position L of the stacking conveyor 36. Further, the base plate 18 is stopped by signals from the third detection device 39 and the rotary encoder 27, and the third motor 28 is started in reverse to move each needle 35 downward, and the leading cake piece is moved upward. K, is placed at the vehicle counterfeit position L (see Figure 9A). Thereafter, each needle 35 is removed from the leading cake piece K by the retraction of the sliding tube 33a of the air cylinder 33, and then retracted along the transfer path R together with the base plate 18, which is retracted rearward. It returns to the original position and waits at the original position in order to pierce the leading cake piece K, with the following cake piece K2.
Then, the above-mentioned stacking operation is repeated for the succeeding cake piece K2, and each cake piece is stacked at the stacking position L' (see Figure 9), and after the stacking is completed, the subsequent process transported to. In addition, the vertical movement distance of the pricking needle 35 for placing the cake pieces in the stacking position L', that is, the forward and reverse rotation time of the third motor 28, corresponds to the number of cake pieces placed in the stacking position L'. Next, the operation and effects of the embodiment having the above-described configuration will be explained.

Now, in this example, the leading cake piece K, is stacked at the stacking station J.
When passing through the cake piece, the needle 35 is moved parallel to the transfer direction of the cake piece, and during this parallel movement, it is moved toward the side of the leading cake piece K to pierce the leading cake piece K. Then, near the end of the parallel movement, the needle 35 is moved up and down to remove the leading cake piece K. The stacking position L on the litter conveyor 36 provided in front of the transfer path R
The needle 35 is placed in place, and after this placement, the needle 35 is returned to its original position.

For this reason, each interlocking operation of the pricking needle 35 with respect to the cake pieces is smoothly controlled, and each cake piece can be accurately positioned relative to the vehicle bond position L', thereby improving the consistency of the dowel state.
It is possible to prevent the cake pieces from being damaged during the stacking operation and to reliably stack each cake piece.

In particular, the forward and backward movement of the pricking needle 35 in the cake piece transfer direction and the
By effectively combining the forward and backward movement in the orthogonal direction of the transfer path R and the vertical movement, each cake piece can be smoothly and automatically moved, which has the effect of contributing to labor saving in the cake manufacturing process. .

That is, in the present invention, when the leading cake piece of a plurality of cake pieces that are separated and transferred in the front-rear direction passes through the piling station, the cake piece is moved in a direction that crosses the transfer path with respect to the side of the transfer path of the cake pieces. A pricking needle, which is arranged to move forward and backward, is moved in parallel in the transfer direction in synchronization with the transfer of the cake piece, and during this parallel movement, the pricking needle is moved toward the side surface of the cake piece. After stabbing the same piece of cake, near the end of the parallel movement, the needle is moved up and down to lift the cake piece and place it in front of the transfer passage, and after this positioning, move the needle back to the original position. By configuring it so that each movement to return to the position is repeated,
Each cake piece is smoothly and accurately placed one after another and loaded onto a car.
This invention is extremely excellent as a method for stacking cake pieces because it can contribute to labor saving in the cake manufacturing process.
