Description

[Detailed Description of the Invention] This invention relates to a bottom paper pasting device for individually pasting bottom papers to the bottom of food products.

In this specification, the term "bottom paper" specifically refers to a piece of paper or a thin piece of other material that is attached to the bottom of a food product.

The purpose of this invention is to individually attach bottom paper to fixed positions on the bottom of foods that are fed in at irregular intervals by a feeding conveyor, and then transfer them to a receiving conveyor and send them out. Work,
It is an object of the present invention to provide a device that can perform the operation automatically and with high accuracy by using a simple configuration.

The structure of the device according to the present invention will be explained in detail based on drawings showing embodiments. In FIGS. 1 to 3, 1 is a cylindrical body, which is rotatably fitted loosely on a fixed shaft 2, and has a driving force. It is rotated in a fixed direction via a motor 3 as a source, an electromagnetic clutch 4, and pulleys 5 and 6. The electromagnetic clutch 4 is used to intermittently force the cylindrical body 1 to rotate at a constant rotation angle in response to commands. Reference numeral 7 denotes a sector-shaped piece, which is fixed on the fixed shaft 2, and whose outer circumferential surface is arranged so as to always maintain contact with a part of the inner circumferential surface of the cylindrical body 1, and a recess 8 is formed on the outer circumferential surface. be done. The recess 8 is connected to a pump 10 as a pressure reducing means by a pipe 9.
connected to. By configuring like this,
No matter what phase the cylindrical body rotates, negative pressure can always be generated on the contact surfaces of the inner and outer peripheral surfaces to which the recesses 8 belong. Reference numeral 11 denotes a tape-shaped bottom paper, which is pressed to an appropriate position on the outer peripheral surface of the cylinder 1 by a roll 12 serving as a bottom paper supply means, and the bottom paper 11 is automatically supplied as the cylinder 1 rotates. be done. As is clear from the figure, the position of the roll 12 on the cylindrical body rotation phase needs to be selected further upstream than the upstream end 8a of the recess 8 of the fan-shaped piece 7. If they are not arranged in this manner, there will be a large number of holes drilled on the outer peripheral surface of the cylinder 1 within the range hidden by the bottom paper 11 so as to penetrate through the thickness of the cylinder and reach the inner peripheral surface. The suction holes 13, 13, . This is because there is a risk that negative pressure may be prevented from being generated due to the presence of air and air intake from this area.

Reference numeral 14 indicates a groove carved in the axial direction on the outer peripheral surface of the cylindrical body 1. When the cylindrical body 1 rotates at a certain rotation angle and comes to rest, the cutter 15 for the bottom paper is inserted into the groove 14.
This is for cutting the bottom paper 11 into a predetermined size by moving it forward and backward. In the illustrated example, the predetermined dimension of the bottom paper 11 is approximately 1/6 of the total circumferential length of the cylindrical body 1. Reference numeral 16 denotes a feed conveyor for the food A, and the food A fed by the conveyor 16 rides on the bottom paper 11' as a short piece adsorbed on the outer peripheral surface of the cylindrical body 1 with its leading end. When the food A reaches this position, the proximity detector 17 installed near the feed conveyor 16 detects the proximity of the food A and sends a signal to the electromagnetic clutch 4, which connects the clutch. The cylindrical body 1 is further rotated by a constant rotation angle. At this time, the food A is completely placed in the fixed position on the bottom paper 11', and the food A
The bottom paper 11' is attached to the base paper 11'. In this state, there is no need to keep the bottom paper 11' attracted to the outer circumferential surface of the cylindrical body 1 by negative pressure, and the bottom paper 11' is released from the negative pressure area caused by the recess 8. Reference numeral 18 denotes a pressing plate, which is a circular plate that can freely rotate around a fixed shaft 19, and is especially provided when a certain amount of pressing force is required to adhere the food and the bottom paper.

20 is a receiving conveyor for receiving the food A to which the bottom paper 11' is attached, and 21 is a scooping piece placed stationary near the receiving conveyor. As shown in FIG. 3, the tip 21a of the scooping piece 21 is installed in a ring-shaped groove 22 provided on the outer circumferential surface of the cylindrical body 1 in a inserted state, and as the cylindrical body 1 rotates. Accordingly, the bottom paper 11' and the confectionery A placed thereon
The tip 21a scoops up the liquid and transfers it onto the receiving conveyor 20. In the illustrated example, three ring-shaped grooves 22 are provided in the cylindrical body 1, and accordingly, the number of fork-shaped tips 21a provided on the scooping piece 21 is also three. show.

Since the proposed device is constructed as described above, the bottom paper is individually pasted at fixed positions on the bottom of the food items sent at irregular intervals by the feeding conveyor, and then the food items are received. The work of transferring the product onto a conveyor and sending it out can be done automatically and with high precision using a simple configuration, which can cause deformation due to excessive external force due to manual work. It is extremely effective when applied to flexible foods or foods where manual handling is prohibited for food hygiene reasons.
