Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a dry matter carrier supply device in a drying oven for pulp-molded paper products.

"Prior art" In the conventional drying oven, the size of the dried product was a small size, such as an egg tray, and it was one type of product, so it was directly dried on the support frame erected on the continuous moving endless chain circulating inside and outside the drying room. A product (immediately after papermaking) was supplied, transferred into a drying chamber, dried, and then the supporting frame was tilted outside the drying chamber to drop the dried product on the supporting frame onto a carry-out conveyor. However, when making large-sized pulp-molded products with a depth of 10 mm and a wall thickness of 5 to 6 mm, such as cushioning materials that cover the upper and lower surfaces of Western-style toilets, and when making different shapes, large-sized intermittent papermaking It must depend on the device.
There is a problem that it is difficult to use the conventional continuous feeding device because several kinds of paper products need to be placed on the supporting frame which is stopped.

[Problems to be Solved by the Invention] The object of the present invention is to obtain a dry matter carrier supply device that smoothly supplies dry matter of a plurality of shapes to a drying furnace by using a carrier.

"Means for solving the problem" In order to achieve the above-mentioned object, the present invention has an inlet at the upper part of the front of the drying chamber, an outlet at the lower part, an endless circulation chain that enters the drying chamber from the inlet and goes out of the drying chamber from the outlet In a drying furnace in which a support frame for dry matter is installed on the chain at equal intervals and a dry matter supply device is provided in front of a front of a drying chamber, the support frame is a rectangular frame lacking a front frame, It is formed to mount a carrier of dry matter on it, a vertical rising part of the chain and a horizontal support lifting device of the support frame are provided in front of the front face, and an end part of the carrier supply conveyor is arranged in the middle of the vertical rising part. However, the horizontal width of the conveyor is smaller than the width of the front frame lacking portion of the support frame, and the terminal end portion is arranged at an internal position of the support frame that rises horizontally, and the support frame rises. Lever upright by & This is constituted by a dry matter carrier supply device in a drying furnace in which a stopper for a standby carrier is pivotally supported and the lever and the stopper are connected by a connecting rod.

[Operation] Accordingly, the support frame 1 is carried out from the outlet 12 to the front side of the front along with the chain 5 moved from the lower outlet 12 of the drying chamber 11 to the front side of the front, and the vertical rising portion 5'of the chain 5 is horizontally supported. The supporting device 1 rises while maintaining the horizontal state by the raising device 6 and the supporting frame 1 raises the lever 8 in the middle of the vertical raising portion 5'and the stopper 9 is raised accordingly, and the stopper 9 stands by on the conveyor 7. 4th carrier 4 '
It is slightly pushed to the right in the drawing to stop, and in this state, the support frame 1 moves the carrier 4 on the end portion 7'of the conveyor 7 to the first position.
Place and lift as shown. When the support frame 1 moves up to a predetermined position (above the dry matter 3 on the carrier 4'on standby), the lever 8 is disengaged from the support frame 1 by its own weight and the rearward pressing of the stopper 9 by the standby carrier 4 '. Since the lever 8 and the stopper 9 are tilted rearward, the standby carrier 4'moves directly below the support frame 1 raised by the conveyor 7, waits for the next support frame 1 to rise, and repeats this. The carrier 4 that has risen enters the drying chamber 11 through the inlet 13 as the chain 5 moves.
The above dried product 3 is dried and the operation which appears from the outlet 12 to the front of the front is repeated.

[Example] An inlet 13 is provided at the upper part of the front of the drying chamber 11 installed on the floor surface 14, an outlet 12 is provided at the lower part, and the inlet 13 enters the drying chamber 11 and the outlet
Continuous endless circulation chains 5 and 5 that exit from the drying chamber 11 are provided in parallel with each other, and support frames 1 of the carrier 4 are installed at equal intervals on the chains 5 and 5. This installation is center pin on both sides of the support frame 1.
The support frames 1 are kept horizontal by guiding one of the guide rollers 16 and 17 at the front and rear ends on both sides by guide guides 18, which support 15 and 15 on chains 5. The support frame 1 appears in front of the drying chamber 11 along with the chains 5 and 5, and a dry matter unloading device 19 is provided at the lower front portion thereof.
Is provided to form a drying oven. The support frame 1 is a rectangular frame lacking a front frame 2, on which a carrier 4 of a dried product 3 can be placed. A vertical rising portion 5'of the chain 5 is formed in front of the front face by the guide sprockets 21 and 22. The upright endless rotating chain 23 provided in front of the rising portion 5'includes front guide rollers 17 on both sides of the support frame 1. The holding claws 24 are projected at equal intervals to form the horizontal support raising device 6 for the support frame 1. The terminal end 7'of the supply conveyor 7 of the carrier 4 is arranged in the middle of the vertical rising portion 5 ', and the conveyor 7 is a roller chain conveyor, and the lateral width thereof is larger than the width of the front frame lacking portion 2 of the supporting frame 1. It is also small, and the end portion 7'is arranged at an internal position of the horizontal state rising support frame 1. Then, the lever 8 which rises by hitting the rear guide roller 16 on one side of the ascending support frame 1 is pivotally supported by the machine frame 25 by a support shaft, and the front end lateral rod 4 of the carrier 4'standby on the conveyor 7 stands by. A stopper 9 for pressing "" forward is pivotally supported on a support shaft, and a lever 8 and a downward arm 8'of the stopper 9 are
9'is connected by a connecting rod 10 so that when the lever 8 is erected, the stopper 9 is also erected so that the front end lateral rod 4 "of the standby carrier 4'can be pushed and slid forward. Length of the lever 8 Is at a position where the lower surface of the support frame 1 rises above the upper surface of the dried material 3 on the standby carrier 4 '.
It is possible to prevent the dried material 3 on the standby carrier 4 ′ from colliding with the ascending support frame 1 by setting the length so as to be out of the range. Reference numeral 26 in the figure denotes a telescopic stopper of the carrier 4, 27 is a telescopic cylinder, 28
Is operated by the support frame 1 which is raised from below by the limit switch for operation of the cylinder 27 (see FIGS. 4 and 5). Reference numeral 29 is a spring for sudden fall braking of the lever 8.

[Effect] Since the present invention is configured as described above, it is possible to smoothly supply the carrier 4 that is intermittently fed onto the support frame 1 that continuously rises with the chains 5 and 5 that are continuously rotating. The effect of being able to smoothly supply a plurality of dried products 3 on the carrier 4 together with the carrier 4 into the drying chamber 11 is provided.
